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)本发明所述的一种具有反冲洗压力自动调节功能的陶瓷真空过滤机,调压机构设于主体的一侧,通过调压机构的设置进而便于手动设定压力,利用压差自动间歇对过滤机构内部的过滤组件进行反冲洗作用,提高了主体的使用效果,即由于在进行反冲洗之前,首先设定调节柱内部的压力,转动转把,则第二丝杆通过第二滑块压缩第二弹簧,则第二弹簧致使阻塞块远离第一流通管,从而增加其压力值,当陶瓷滤板上的杂质较多时,则进液孔内部液体压力增大,则液体顶推阻塞块进入到第一流通孔的内部,从而对陶瓷滤板进行反冲洗作用,当进液孔内部的压力值减小后,阻塞块复位阻塞,则冲洗停止,进而便于手动设定压力,利用压差自动间歇对过滤机构内部的过滤组件进行反冲洗作用,提高了主体的使用效果。(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.
