beneficial effect

Beneficial effects of the present invention:

(1) The ceramic vacuum filter with automatic adjustment function of backwashing pressure according to the present invention is arranged at the bottom end of the main body through the placement mechanism, and the placement of the placement mechanism facilitates the fixing and placement of the main body in the desired position, The connection mechanism is arranged on both sides of the main body, and the connection mechanism is arranged to facilitate the quick connection of the external pipes, thereby improving the connection speed between the pipes and improving the connection efficiency. The limit holes are aligned with the fixing holes that need to be connected, and then the main body is limited and fixed through the connecting parts. The arrangement of multiple pillars improves the firmness of the main body when it is fixed, and thus facilitates the main body to be fixed and placed in the desired position, that is, Because when the liquid outlet pipe or liquid inlet pipe needs to be quickly docked to the external pipeline, the flange is first docked to the external flange, a plurality of limit bolts are inserted into the holes of the external flange, and the rotating rod is rotated. The rotating rod causes the first screw rod to displace inside the limit bolt, then the bottom end of the first screw rod abuts against the first slider, and the passively compressed first spring causes the contact block to squeeze a plurality of limit balls, and the limit The ball protrudes to the outside of the limit bolt, so as to complete the current fixing operation, and operate multiple rotating rods in this way to complete the pipe docking work, which facilitates the rapid docking of external pipes, thereby improving the docking speed between pipes and improving its connection efficiency.

The setting of the filter mechanism facilitates the filtering of the circulating liquid, and can also perform backwashing on the filter components at the same time. The components can be recycled, which improves the user experience of the main body, that is, when the liquid mixed with gas enters the inside of the gas choke chamber through the liquid inlet hole, because the gas cannot cause the floating ball to rise, the sealing plate always seals the liquid outlet hole, Make the gas unable to pass through. When the liquid enters through the liquid inlet hole, the liquid causes the float ball to rise under the action of buoyancy, and the deflection of the connecting rod drives the sealing plate not to seal the liquid outlet hole, thereby preventing the gas mixed in the liquid from passing through. , to avoid gas oxidation of the internal parts of the main body, to ensure the service life of the main body, that is, because the differential motor is started before the liquid passes through the main body, the differential motor drives the turntable to rotate at a constant speed through the rotating shaft, and the ceramic filter plate inside the turntable rotates at the same time.

(3) A ceramic vacuum filter with automatic adjustment function of backwash pressure according to the present invention. The filter element inside the filter mechanism is intermittently backwashed, which improves the use effect of the main body. That is, because the pressure inside the adjustment column is first set before backwashing, and the handle is turned, the second screw rod passes through the second slide. When the block compresses the second spring, the second spring causes the blocking block to be far away from the first flow pipe, thereby increasing its pressure value. When there are many impurities on the ceramic filter plate, the liquid pressure inside the liquid inlet hole increases, and the liquid pushes the block. The block enters the inside of the first flow hole, so as to perform backwashing on the ceramic filter plate. When the pressure value inside the liquid inlet hole is reduced, the blocking block is reset and blocked, and the flushing stops, which is convenient for manual pressure setting. The differential automatic intermittently backwashes the filter components inside the filter mechanism, which improves the use effect of the main body.
