During the sliding process of the leaf 11, the leaf 11 will drive the guide block 18 to move. Since the guide block 18 is slidably connected to the inside of the guide groove, the leaf 11 will rotate slightly and generate an inclination angle during the expansion process. The leaf 11 in this state has a better stirring effect on the original liquid. When the leaf 11 merges with each other, the leaf 11 is leveled again, which is convenient for cleaning the surface of the leaf 11.

[0026] A pressure regulating plate 19 is provided at the top of the reaction chamber, and the pressure regulating plate 19 is slidably connected to the stirring shaft 3; a receiving plate 20 is fixedly connected to the top of the support ring; a connecting groove is provided on the bottom surface of the pressure regulating plate 19; a first connecting groove is provided on the side of the receiving plate 20; a first sliding groove is provided on the side of the connecting groove; a first connecting pipe 17 is connected between the first sliding groove and the air guide ring 14; a first control valve is provided inside the first connecting pipe 17; a first slider 21 is slidably connected inside the first sliding groove; a second sliding groove is provided on the side of the pressure regulating plate 19; a second connecting pipe 17 is connected between the second sliding groove and the air guide ring 14; a second control valve is provided inside the second connecting pipe 17; a second slider 22 is slidably connected inside the second sliding groove; the reaction chamber A second connecting groove is provided on the side; when working, by setting the first slider 21 and the second slider 22, by controlling the first connecting pipe 17 and the second connecting pipe 17 to be connected, the first slider 21 and the second slider 22 will be driven to slide under the action of air pressure.

A large number of solid particles can be effectively filtered through the filter screen 35 to ensure the long-term stable operation of the pressure regulating tube 31. At the same time, when the fluid flows forward and backward inside the pressure regulating tube 31, it can also promote the cleaning of the filter screen 35.

[0032] The inside of the pressure regulating pipe 31 is rotatably connected to a spray disc near the bottom filter 35; the spray disc is provided with an inclined hole 36 on one side relative to the filter 35; the spray disc is fixedly connected to a nozzle 37 on one side relative to the filter 35; during operation, by setting the spray disc, when the fluid flows into the pressure regulating pipe 31, the fluid will pass through the spray disc, and when the fluid flows downward, the flow will be ejected through the inclined hole 36, which promotes the rotation of the spray disc, so that the liquid ejected by the nozzle 37 can be evenly sprayed onto the surface of the filter 35 at high pressure, further improving the cleaning effect of the surface of the filter 35, and when the flow moves upward, the fluid will pass through the inclined hole 36 and pass through the spray disc to flow upward normally. Since the surface of the filter 35 at the bottom position is easily in direct contact with the sediment, the surface is easy to firmly adhere to and fix the sediment, and this design can be used exclusively for effective cleaning of the surface of the filter 35 at the bottom position.

[0033] Working principle: first, the raw materials are introduced through the feed pipe 4, and then the motor 2 is started. The rotation of the motor 2 will drive the stirring shaft 3 and the stirring block 9 to rotate. At the same time, through the first telescopic rod 6, the first telescopic rod 6 will drive the connecting block 7 to move up and down, the connecting block 7 will drive the fixed ring 8 to move, and the fixed ring 8 will drive the stirring block 9 to move up and down, so that the stirring block 9 can be adjusted up and down while rotating, so as to promote the rapid mixing of different raw liquid layers inside the reactor; by setting the support block 10, the leaf 11 and the elastic sheet 12, by controlling the gas conduction, the gas will enter the air guide ring 14 through the air guide pipe 15, and then enter the connecting hole 16 through the air guide ring 14, and then enter the connecting hole 16 through the connecting hole 16 is introduced into the connecting pipe 17, and finally into the pressure tank, and the internal pressure of the pressure tank of the leaflets 11 is adjusted, so that the leaflets 11 can be quickly dispersed and merged, and the merged leaflets 11 are convenient for cleaning their surfaces, and the leaflets 11 in a dispersed state can be convenient for fully mixing the inside of the reactor, and the fully expanded leaflets 11 can directly fit with the inner wall of the reactor, and when the leaflets 11 rotate, the inside of the reactor can be automatically cleaned; by providing a guide groove inside the pressure tank, and the guide groove is designed in a spiral structure, when the internal air pressure of the pressure tank increases, the leaflets 11 and the guide pillars 13 will slide relative to each other, and the leaflets 1 During the sliding process, the leaf 11 will drive the guide block 18 to move.

The leaf 11 in this state has a better stirring effect on the stock solution. When the leaf 11 merges with each other, the leaf 11 is re-leveled, which is convenient for cleaning the surface of the leaf 11. By setting the first slider 21 and the second slider 22, by controlling the first connecting pipe 17 and the second connecting pipe 17 to be connected, the air pressure will drive the first slider 21 and the second slider 22 to slide. Before this, the first telescopic rod 6 will drive the receiving plate 20 to move to the inside of the receiving groove, and then the first The slider 21 will automatically be inserted into the first connecting groove, so that the pressure regulating plate 19 is connected to the receiving plate 20, and the second slider 22 will be retracted into the corresponding second sliding groove, so that the second slider 22 is separated from the second connecting groove. The pressure regulating plate 19 will move up and down with the expansion and contraction of the first telescopic rod 6 to regulate the pressure inside the reaction chamber. When the pressure regulating plate 19 moves downward, the air pressure below it will increase, thereby promoting the conduction of the discharge pipe 5 in the blocked state; by providing a pressure regulating spray hole 23 on the surface of the pressure regulating plate 19, when the pressure regulating plate 19 moves up and down, the pressure regulating spray hole 23 can conduct gas up and down, avoiding excessive pressure difference between the upper and lower parts of the pressure regulating chamber, which affects the safe operation of the equipment;By setting the second telescopic rod 24, the extension and retraction of the second telescopic rod 24 will drive the push block 25 to move, the push block 25 will drive the inner ring 26 to move, and the movement of the inner ring 26 will drive the first spring 28 to extend and deform. When the first spring 28 is in a stretched state, the first spring 28 will squeeze the telescopic tube 27, so that the inner diameter of the elastic membrane 29 changes. When a blockage problem occurs at the position of the elastic membrane 29, the inner diameter of the elastic membrane 29 is reduced. At this time, the elastic membrane 29 will squeeze the blockage inside it, and then control the first spring 28 to extend, and at this time, the inside of the elastic membrane 29 will recover. , promoting the discharge of the blockage inside the discharge pipe 5; by setting the vibration block 30, when the first spring 28 is extended and retracted, the first spring 28 squeezes the vibration block 30, and generates vibration and partial retraction, thereby promoting the squeezing and vibration of the elastic membrane 29, increasing the squeezing of the blockage and improving the discharge promoting effect; by setting the pressure regulating tube 31, when the pressure regulating plate 19 moves up and down, a large pressure difference will be generated between the upper and lower parts of the pressure regulating plate 19, the fluid will move up and down through the pressure regulating spray hole 23, and the fluid will drive the pressure regulating block 34 to move up and down, so that the pressure regulating tube 31 in the blocked state will automatically open Due to the pressure of the second spring 33, automatic pressure regulation can be achieved, and the flow rate of the pressure regulating spray hole 23 can be adjusted; by setting the filter screen, when the pressure regulating plate 19 moves to the position of the raw liquid level, the fixed objects inside the raw liquid can easily pass through the inside of the pressure regulating tube 31 and block the pressure regulating tube 31. A large number of solid particles can be effectively filtered through the filter screen 35 to ensure the long-term stable operation of the pressure regulating tube 31. At the same time, when the fluid flows forward and backward inside the pressure regulating tube 31, it can also promote the cleaning of the filter screen 35; by setting the spray plate, when the fluid flows into the pressure regulating tube 31, the fluid When the fluid flows downward, it will be ejected through the inclined hole 36, which will promote the rotation of the spray plate, so that the liquid ejected by the nozzle 37 can be evenly sprayed at high pressure on the surface of the filter 35, further improving the cleaning effect on the surface of the filter 35. When the fluid moves upward, it will pass through the inclined hole 36 and pass through the spray plate to flow upward normally. Since the surface of the filter 35 at the bottom position is easily in direct contact with the sediment, the surface is easy to firmly adhere to and fix the sediment. Through this design, it can be used exclusively for the effective cleaning of the surface of the filter 35 at the bottom position. ;
