Description

A kind of anti-device that dabbles of taper dissolvers

Technical field

Belong to environmental technology field, exactly, relate to be used for the environment protection sewage treatment technology and add technology about the dissolving of flocculant.

Background technology

In sewage treatment industry, the sludge dewatering operation that is absolutely necessary, yet, in the dewatering technology of mud flow process, must in sewage, add high molecular polymer (being commonly called as " flocculant "), can reach the purpose of Separation of Solid and Liquid.Because the high molecular polymer that adopts in the sewage industry mostly is solid matter at present, therefore, needs special equipment that it is dissolved the flocculant solution that is mixed with certain concentration.And " two-box type high polymer coagulant dissolving throwing device " is wherein a kind of, the flocculating polymer agent solution homogeneous of preparing for making has activity, and this device has been equipped with high polymer coagulant dry powder spiral powder conveying device, spiral powder conveying device outlet steam prevents valve, preliminary wetting device taper dissolvers, mixes accelerator (being commonly called as " water sprayer ").In process for preparation, after the circulation of the water in the preliminary wetting device taper dissolvers forms, spiral powder conveying device steam prevents that valve from opening earlier, high molecular polymer dry powder is put in the taper dissolvers by helix transporting device then, this subsequently high molecular polymer mixed solution that is soaked that has is transported in the make-up tank after accelerator (water sprayer) quickens by mixing, and stirs slaking.

But there are many problems that influences work in its device in practical work process, be summarized as follows:

1, because high molecular polymer solid powder water imbibition is very strong, very easily making moist, is something of extremely paying close attention in the industry to the dry powder protection against the tide before the obtain solution therefore;

2, owing to the mechanism and the big reason of molecular weight thereof of macromolecule polymer material, therefore in a single day its dry powder make moist, viscosity is very big, the machine driving and the hermetic unit of " dissolving throwing device ", if because of steam or the globule cause surface wetting, dry powder very easily is bonded on transmission device and the seal because of humidity, makes these parts cisco unity malfunctions when serious and causes the package unit paralysis;

3, mixing accelerator (water sprayer) is to utilize fluid to transmit energy and quality, it is sprayed at a high speed by nozzle by the working fluid with certain pressure (water), make pressure can change into the speed energy, form vacuum in the jet expansion zone, thereby another strand medium is sucked, two strands of media mix in diffuser pipe and energy exchange, and make speed can be reduced into the pressure energy, discharge to be higher than atmospheric pressure at last.When this strand mixed solution from the taper dissolvers enters the vacuum area that mixes accelerator, the vacuum that forms at the fluid that is sprayed at a high speed by nozzle sucks the moment of mixing, strong impaction takes place in the jet expansion zone of mixing accelerator in these two strands of media, produce a large amount of globules thus, because under the effect of pressure energy and speed energy, these globules carry out random motion in mixing accelerator jet expansion zone.Because of the circulation of the water in the taper dissolvers need form a huge vortex because of technological requirement, this provides the passage that moves upward with regard to the globule of giving random motion again.

4, prevent valve though installed steam additional in the outlet of dry powder helix transporting device, but just controlling table does not effect a permanent cure, when preparation flocculating polymer agent solution, mixing accelerator (water sprayer) starts working earlier, and prevent that valve from opening and when beginning defeated powder at steam, have the globule that moves upward from the mixing accelerator in a large number and make the spiral powder conveying device outlet, steam prevents that the sealing surface of valve and bottom from making moist, when defeated powder finishes after steam prevents that valve from cutting out, the steam that makes moist prevents that valve sealing surface can be stained with a large amount of high polymer coagulant dry powder in the spiral powder conveying device exit, treat down to be made moist again by sticking dry powder when task is opened, glue dry powder when closing again again in the spiral powder conveying device exit again.And so forth, make steam prevent that the high polymer coagulant dry powder of valve sealing surface is sticking more many more, also knot is big more more for piece, finally makes steam prevent that valve from can not cut out, and has lost the effect that sealing and steam prevent.

5, after steam prevents that valve is ineffective, the globule that moves upward just can make the powder screw rod that pushes away in the spiral powder conveying device make moist, in like manner, macromolecule dry powder can be bonded at again and push away on the powder screw rod, and in screw chamber, lump, make to push away the powder screw rod and can't work, and make the package unit paralysis.

6, because the globule that moves upward makes the dry powder of the screw chamber caking that makes moist, high polymer coagulant behind the caking mixes accelerator (water sprayer) suction chamber if fall into, the suction inlet that mixes accelerator (water sprayer) is stopped up, cause whole device to move.

7, be generally equipment is moved continuously, in equipment uses, be forced to remove steam and prevent valve, irregular then employing manual method is clear lumps, thereby has caused the waste (market price of macromolecule dry powder is very high) of a large amount of macromolecule dry powder, increases user's production cost.

Because the existence of the problems referred to above, be to perplex this kind equipment safety in the industry, a difficult problem stable, that move continuously always, so mixing accelerator (water sprayer) jet expansion zone, prevention moves upward by the vortex hole after the water circulation formation of taper dissolvers again because of the globule that two strands of media bumps produce random motion, it is this kind equipment problem demanding prompt solution in the industry, also be to guarantee that can " two-box type high polymer coagulant dissolving throwing device " operate as normal, can give play to should efficient unique measure.

Summary of the invention

The invention provides a kind of the change under the original device running status, use the simple possible way, the passage that the blocking-up globule moves upward is avoided dissolving throwing device and is made moist, and can bring into play the anti-device that dabbles of a kind of taper dissolvers of device efficiency again.

The technical scheme that the present invention takes:

A kind of anti-device that dabbles of taper dissolvers is made up of taper dissolvers, water sprayer, spiral powder conveying device and water inlet pipe; The taper dissolvers is for being inverted the hollow upright body of taper of installing, and little mouth down is by seal welding around outlet pipe and the water sprayer suction chamber opening up; Water sprayer is made up of the nozzle of an end, the suction chamber of centre and the diffuser pipe closed conduit of the other end; Cone towards upper shed facing to the meal outlet of spiral powder conveying device, the water dam that can push open when meal outlet has a feeding; Outward flange big mouthful of cone, along water inlet pipe that constitutes water circulation moisture film in the hollow cone of the parallel introducing of awl wall, constitute this device, its scheme is: the symmetrical centre in taper dissolvers and outlet pipe junction, an inverted T type support is arranged, the two ends of T font horizontal stroke and the welding of two tube walls, the vertical end of T is stretched in the conical vessel, there is screw thread the end, with settle it on steel ball on the nut that welded twist mutually and cooperate; Steel ball size is 3/4ths to 4/5ths of cone level position, a steel ball place diameter.Described steel ball, also can be and the flat board of steel ball with the horizontal setting of diameter, or with the dome of the diameter half steel ball of umbrella shape up.
