Description

A diffusion formula dust remover for clay sand is handled

Technical Field

The utility model relates to a casting field especially relates to a diffusion formula dust remover for clay sand is handled.

Background

At present, each work part of casting workshop pouring, cooling, shakeout, sand treatment and the like can generate dust in the production process, and a dust remover is usually arranged at each dust point. The dust collector is a device for separating dust from flue gas, and the most commonly used dust collector at present is a bag-type dust collector, for example, a bag-type dust collector is disclosed in patent No. CN 200820217064.7. The air purifier is characterized in that a box body is divided into an upper purified air space and a lower filtering space through a pattern plate arranged in the horizontal direction, two flat partition plates extend downwards from the lower surface of the pattern plate along the vertical direction, the space between the two partition plates is an air channel, the space between the partition plates and the box body is a bag chamber, the air channel is divided into a channel containing an air inlet and a channel containing an air outlet by a guide plate, the air inlet is directly communicated with the filtering space, the air outlet is communicated with the purified air space through an air outlet branch opening on the pattern plate, and a plurality of filter bags are suspended in the bag chamber. The principle is that air containing dust is sucked into a filter chamber, particles directly fall into a dust bin when being large, the rest particles are blocked on the surface layer of the filter bag after being filtered by the filter bag, clean gas enters a gas purifying chamber and then is discharged into the atmosphere through a fan, however, a large number of filter bags are usually arranged in the equipment, when a single filter bag is damaged, the filter bag is not easy to pick out, and therefore the situation that part of dust is discharged into the air along with the gas can be avoided, and the dust-collecting device is inconvenient to use.

Current patent No. 201320395672.8 discloses a diffusion formula cyclone, including rotatory barrel, the air-supply line goes out the tuber pipe, goes out the ash door and unloads grey valve automatically, rotatory barrel divide into upper and lower two parts, upper portion is cylindrical, the lower part is big-end-up's taper shape, the air-supply line encircles and locates rotatory barrel top, with the tangent connection of the rotatory barrel that shows, it follows to go out the tuber pipe inside rotatory barrel top stretches into rotatory barrel, rotatory barrel lower part is equipped with the ash door, rotatory barrel lower extreme has the ash hole, and connects the automatic ash valve that unloads. The diffusion type cyclone dust collector disclosed by the invention has the characteristics of simple structure and obvious dust collection effect, but the dust collector needs to be stopped when discharging ash, so that the dust collection efficiency is influenced.

Therefore, to foretell problem, the utility model provides a diffusion formula dust remover for clay sand is handled, it need not to shut down can clear up dust in the ash bucket, improves deashing efficiency.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a diffusion formula dust remover for clay sand is handled, is including being cylindrical barrel, the air-supply line that sets up with the barrel is tangent, locate the play tuber pipe of barrel top and locate the ash bucket of barrel below, the bottom of ash bucket is equipped with the ash pipe, the inside both ends of ash pipe are equipped with the spiral discharge bar through the bearing, the spiral discharge bar includes the pivot and locates the epaxial helical blade of commentaries on classics, one side of ash pipe lower extreme is equipped with the ash hole, the one end that the ash hole was kept away from in the pivot extends to the barrel and forms the auxiliary shaft, be equipped with the blade on the free end of auxiliary shaft.

In a further improvement, the free end of the auxiliary shaft is lower than the lower end of the air outlet pipe.

Further improved, one end of the air outlet pipe communicated with the cylinder body is provided with an ash blocking device.

In a further improvement, the ash blocking device is a filter screen.

By adopting the technical scheme, the beneficial effects of the utility model are that: through the utility model discloses the ash can be unloaded to the ash bucket when removing dust, prevent that the dust that falls into the ash bucket from rolling up again and being taken out by the updraft, has improved dust collection efficiency greatly, and it is through the spiral discharge bar that sets up, when unloading the ash, can make the ash bucket cut off with outside atmospheric pressure, prevent that the gas from leaking when equipment moves, influence the dust removal effect, simultaneously, extend one end of spiral discharge bar to the barrel inside and form the auxiliary shaft and be equipped with the blade on the free end of auxiliary shaft, increase the cyclone velocity of flow in the feed cylinder, strengthen the purifying effect of dirty gas, the utility model discloses the structure is more simple, compact; furthermore, through setting up ash blocking device, further guarantee dust removal effect.
