SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a side connection formula membrane shell filter to solve the inside partial space of filter and be detained gaseous and occupy, lead to the inside atmospheric pressure of filter to increase, influence the problem of the filtration efficiency of filter.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a side connection formula membrane shell filter, includes first filter, install the second filter on the first filter, be equipped with pressure release hole and backward flow hole between first filter and the second filter, the downthehole cover of pressure release is equipped with the piston, install spring and movable rod on the piston, the one end of spring is installed on the inner wall in pressure release hole.
Preferably, the backflow hole is internally provided with a one-way valve, water inside the second filter flows into the first filter through the backflow hole, and the water flow direction inside the backflow hole is limited by the one-way valve, so that the situation that water inside the first filter enters the second filter through the backflow hole is avoided.
Preferably, the fixed column is installed in the pressure relief hole, a telescopic groove is formed in the fixed column, the movable rod is sleeved in the telescopic groove, the moving track of the piston is limited through the movable rod and the telescopic groove, and the situation that the pressure relief hole cannot be blocked due to piston dislocation is avoided.
Preferably, the inner wall of the second filter is provided with a first vent hole through which air above the second filter can be discharged.
Preferably, a second vent hole is formed in the inner wall of the second filter, one end of the second vent hole is communicated with the first vent hole, and air at the lower part of the second filter can be discharged through the second vent hole.
Preferably, a sealing bolt is installed at the upper end of the first vent hole, a sealing thread is arranged at the upper end of the first vent hole, and the sealing bolt is installed in the first vent hole through the sealing thread and can block the upper end of the first vent hole.
Compared with the prior art, the beneficial effects of the utility model are that: the piston is pushed by air pressure in the first filter, so that air and water flow in the first filter enter the second filter through the pressure relief hole, the pressure in the first filter can be relieved, and the condition that the filtration is influenced by overlarge air pressure in the first filter is avoided; through unscrewing sealing bolt for the inside gas of second filter is emitted through first air vent and second air vent, avoids appearing the inside atmospheric pressure of second filter and risees the condition that leads to the inside unable pressure release of first filter.

FIG. 1 is a front cross-sectional view of the overall structure of the present invention;
fig. 2 is an enlarged view of a point a in fig. 1 according to the present invention;
fig. 3 is a front cross-sectional view of the fixing column of the present invention.
In the figure: the device comprises a first filter 1, a second filter 2, a pressure relief hole 3, a backflow hole 4, a piston 5, a spring 6, a movable rod 7, a one-way valve 8, a fixed column 9, a telescopic groove 10, a first vent hole 11, a second vent hole 12 and a sealing bolt 13.
Detailed Description
Referring to fig. 1 and 2, a side-connected membrane shell filter includes a first filter 1, a second filter 2 is mounted on the first filter 1 through a screw, a pressure relief hole 3 and a backflow hole 4 are disposed between the first filter 1 and the second filter 2, a piston 5 is sleeved in the pressure relief hole 3, the piston 5 can block one end of the pressure relief hole 3, a spring 6 and a movable rod 7 are mounted on the piston 5 through a screw, and one end of the spring 6 is mounted on an inner wall of the pressure relief hole 3 through a screw.
Referring to fig. 1, a check valve 8 is installed in the backflow hole 4 through a screw, water inside the second filter 2 flows into the first filter 1 through the backflow hole 4, and the check valve 8 limits the direction of the water inside the backflow hole 4, so that the water inside the first filter 1 is prevented from entering the second filter 2 through the backflow hole 4.
Referring to fig. 2 and 3, a fixed column 9 is installed in the pressure relief hole 3 through a screw, a telescopic groove 10 is arranged in the fixed column 9, the movable rod 7 is sleeved in the telescopic groove 10, and the movable rod 7 and the telescopic groove 10 limit the moving track of the piston 5, so that the situation that the piston 5 is dislocated and cannot block the pressure relief hole 3 is avoided.
Referring to fig. 1, a first vent hole 11 is formed in an inner wall of the second filter 2, and air at an upper portion of the second filter 2 can be discharged through the first vent hole 11.
Referring to fig. 1, a second vent hole 12 is formed in an inner wall of the second filter 2, one end of the second vent hole 12 is communicated with the first vent hole 11, and air at a lower portion of the second filter 2 can be discharged through the second vent hole 12.
