The utility model provides an auxiliary type valve filter equipment is still including collecting lid 130 and baffle 131, collect lid 130 slidable mounting in shell 120, collect lid 130 slidable mounting in collecting box 140, baffle 131 is the L shape, baffle 131 includes vertical section and the horizontal segment with the perpendicular setting of vertical section, the shifting chute has been seted up on the shell 120 of row's cinder notch 127 lower extreme, vertical section slidable mounting is in the shifting chute, horizontal segment fixed mounting is in collecting lid 130, when collecting lid 130 and moving up, drive baffle 131 and shift up, block row's cinder notch 127. The collecting box 140 is detachably connected with the housing 120, and can be specifically designed to be clamped, inserted and the like, so that the collecting box 140 is convenient to clean.
The working process is as follows: in use, the housing 120 is flanged to a pipe to be installed. Since the flushing chamber is always sealed, in use, the liquid will only pass through the filter mesh of the first filter element 150 to filter the liquid in the pipe, the filtered liquid will pass through the valve 110, and the second filter element 160, the back flushing chamber 240 and the collection tank 140 will be filled. As the filtering process proceeds, the filter net disposed on the first filter 150 is gradually blocked, and when the filter net is blocked to a certain extent, the liquid will push the filter net on the first filter 150, and then push the first filter 150 to move along the first sliding slot 125, and the movement of the first filter 150 will drive the sealing member 170 to move upwards synchronously, so that the volume of the back washing chamber 240 between the second filter 160 and the sealing member 170 becomes smaller gradually.
The first filter plate moves upwards to extrude the pressure spring 220 in the elastic tube 124, hydraulic oil in the elastic tube 124 flows to the second transmission member 190 through the connecting tube 191, the second transmission member 190 pushes the first transmission member 183 to make the first transmission member 183 extrude the sliding block 181, the sliding block 181 contacts with the first stopper 182, due to the blocking of the first stopper 182, the spring between the first transmission member 183 and the sliding block 181 keeps continuously storing force, in this process, the first filter member 150 continues to move upwards along the first sliding slot, after the sliding block 161 arranged on the first filter member 150 slides to the first annular groove 123, the sliding block 181 can make the first stopper 182 compress over the first stopper 182 by setting, the sliding block 181 pushes the synchronous block 230 fixedly arranged on the first filter member 150 to rotate under the action of the pressure spring 220, and the synchronous block 230 rotates to drive the first filter member 150 to rotate.
The first filter 150 rotates to push the second filter 160 to rotate, when the sliding block 161 of the second filter 160 is located at the communication position between the first sliding slot 125 and the first annular slot 123 in the filter cavity when rotating, because the filter screen of the second filter 160 is not blocked, the pressure spring 220 resets at this time, under the action of the pressure spring 220, the second filter 160 moves down rapidly along the first sliding slot 125 in the filter cavity, and simultaneously drives the sealing element 170 at the lower end of the second filter to move down, so that the space of the backflushing cavity gradually increases, after the sliding block 161 of the second filter 160 moves to the lowest end of the first sliding slot 125 in the filter cavity, the second filter 160 starts to work normally instead of the first filter 150, the liquid flows out of the valve 110 after being filtered by the second filter 160, and simultaneously, the liquid backflushes the impurities on the first filter 150 downward from the opening at the upper end of the first filter 150. The impurities which are back-flushed down flow into the collecting box 140 through the first sealing plate 171 and settle at the bottom of the collecting box 140, so that the first circulation is completed, and after the filter screen of the second filter element 160 is blocked, the process is repeated by the cleaned first filter element 150, so that the work of the device is ensured.
When the impurities in the collection box 140 need to be cleaned, the operator moves the collection cover 130 upwards to move the baffle 131 upwards to seal the slag discharge opening 127, and then the collection box 140 is detached and cleaned and then installed again.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
