Description

A kind of injection production filter device

Technical field

The utility model relates to filter plant field, specifically a kind of injection produces filter device.

Background technique

Injection production need by concentrated compounding, it is dilute with etc. carry out after processes it is filling, injection dilute preparing tank and bottle placer it Between when being conveyed, intermediate generally to pass through multistage filtering, the general filter using 0.45 μm and 0.22 μm, which is connected, carry out Filter；Filter can block after filtering for a long time, and liquid medicine flow is unsmooth after plugged filter, filter effect decline, Working efficiency reduces；Staff directly cannot rapidly know the stopping state of filter in the prior art, therefore often occur Filter replacement not in time the problem of；In addition, filter needs to shut down once blocking to be replaced, and it is cumbersome, it influences just Often production, reduces working efficiency.

Utility model content

For above situation, for the defect for overcoming the prior art, the utility model provides a kind of injection production filtering Device, the current injection production filter of effective solution is readily replaceable not in time, replaces inconvenient problem.

Its technical solution solved is a kind of injection production filter device, including vertical columned shell, shell Left side wall on be provided with inlet, be provided with liquid outlet on right side wall, the lower ending opening of shell and be installed with first end cover through screw thread, Shell is provided with a rotatable columned strainer, and the outer wall of strainer is bonded with the inner wall of shell and strainer and shell inner cavity It is contour；It is equipped with a shaft at the axis of strainer, multiple connecting rods are connected between shaft and strainer inner wall, the lower end of shaft is stretched Out outside end cap；A vertical through-hole is provided on the left side wall of shell, through-hole lower end is communicated with inlet, and one is equipped in through-hole A vertical bar that can be gone up and down with the water pressure at inlet, vertical bar upper end is stretched out outside through-hole.

The utility model can easily know the stopping state of strainer, remind staff to handle in time, be by shaft Screen location can be quickly adjusted, the number for shutting down replacement strainer is greatly reduced, reduces workload, improve work efficiency.

Detailed description of the invention

Fig. 2 is the utility model front sectional view.

Fig. 3 is part A enlarged drawing in Fig. 2.

Specific embodiment

Further description is made to specific embodiment of the present utility model below in conjunction with attached drawing.

It is provided by Fig. 1 to Fig. 3, the utility model includes vertical columned shell 1, is provided on the left side wall of shell 1 Inlet 2, is provided with liquid outlet 3 on right side wall, the lower ending opening of shell 1 and is installed with first end cover 4 through screw thread, and shell 1 is built-in There is a rotatable columned strainer 5, the outer wall of strainer 5 is bonded with the inner wall of shell 1 and strainer 5 and 1 inner cavity of shell etc. It is high；It is equipped with a shaft 6 at the axis of strainer 5, is connected with multiple connecting rods 7 between 5 inner wall of shaft 6 and strainer, under shaft 6 End is stretched out outside end cap；A vertical through-hole 8 is provided on the left side wall of shell 1,8 lower end of through-hole is communicated with inlet 2, through-hole 8 One vertical bar 9 that can be gone up and down with the water pressure at inlet 2 is inside installed, 9 upper end of vertical bar is stretched out outside through-hole 8.

The vertical bar 9 is thick ladder-like in the thin lower end in upper end, and 8 upper end of through-hole is installed with second end cover 10, vertical bar 9 it is upper End is stretched out outside second end cover 10, and a pressure spring 11, the upper end of pressure spring 11 and second end cover 10 are set on the thin rod portion of vertical bar 9 Following table face contact, the upper end face contact of the wide bar section of lower end and vertical bar 9.

For the leakproofness for guaranteeing shell 1, first sealing ring 12, vertical bar are installed between the shaft 6 and first end cover 4 Second sealing ring 13 is installed between 9 and second end cover 10.

To be equipped with a turret head 14 convenient for the lower end of rotating shaft 6, the shaft 6.

For the axial position convenient for knowing strainer 5, the lower end of the shaft 6 be equipped with circumference to scale.

For the utility model when specifically used, inlet 2 connects inlet tube, and liquid outlet 3 connects outlet tube, injection liquid It flows into shell 1 through inlet 2, is flowed out after the filtering of strainer 5 by liquid outlet 3；When inlet 2 and liquid outlet 3 to position Strainer 5 is after filtering after a period of time is blocked, and liquid medicine flow is obstructed unsmooth, then the medical fluid pressure at inlet 2 can increase, With the medical fluid pressure rise at inlet 2, medical fluid increases the pressure of 9 bottom of vertical bar, then the pressure increased will push vertical bar 9 The elastic force of pressure spring 11 is overcome gradually to move upwards, vertical bar 9 moves upwards more, shows that strainer 5 blocks more serious, and work people Member can know the stopping state of strainer 5 by observing the height on 9 top of vertical bar, when the arrival of 5 chocking-up degree of strainer needs replacing When, staff twists the turret head 14 of 6 lower end of shaft by spanner, so that shaft 6 be made to rotate, shaft 6 passes through connection Bar 7 is rotated with electric filter 5, and 5 part of strainer being blocked at inlet 2 and liquid outlet 3 is replaced with not blocked part；Filter After net 5 rotates, liquid medicine flow be not obstructed, and the hydraulic pressure decline at inlet 2 reduces the pressure of 9 bottom of vertical bar, in pressure spring 11 Under the action of, vertical bar 9 declines.

Staff can know shaft 6 has rotated how many degree altogether by the scale in shaft 6, when 6 rotational angle of shaft reaches To after 180 degree, illustrate strainer 5 all using finishing, next time needs replacing new strainer 5 when blocking；Replacing options are as follows: first The switch for first closing inlet tube, then backs out first end cover 4, takes out strainer 5 and shaft 6, new strainer 5 and shaft 6 are installed In shell 1, first end cover 4 is then screwed on；The strainer 5 removed carries out cleaning in case replacement next time uses.

The utility model has the significant advantage that firstly, would know that the stopping state of strainer 5 by the height of vertical bar 9, with Just it is handled in time, prevents that the blocking of strainer 5 is answered to influence filter effect and working efficiency；In addition, strainer 5 is designed to column, The position of strainer 5 can easily be adjusted by rotating strainer 5 by shaft 6, can quickly be blocked strainer 5 when strainer 5 blocks Partial replacement fall, do not have to shutdown operation, it is simple and quick, after entire strainer 5 be blocked after shut down the strainer 5 more renewed again, Machine stop times are greatly reduced, and are replaced conveniently, it is easy to operate.
