Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment equipment, and in particular to an ultrafiltration membrane sewage guiding and filtering component. Background Art

[0002] Ultrafiltration membrane is a kind of efficient separation membrane, which is widely used in the field of sewage treatment. Under the action of high pressure, the solvent and some low-energy solutes in the solution can reach the other end of the membrane through the tiny holes on the membrane, which has an interception effect on molecular and high-quality dissolution, and screens colloidal substances. At the same time, the surface of the membrane has chemical properties to intercept a small amount of substances. When the solution is ultrafiltered, pressure is applied to the solution so that inorganic salts, water and low-molecular substances pass through the ultrafiltration membrane, and high-molecular substances and colloids are intercepted to achieve the purpose of water purification.

[0003] The prior art discloses some invention patents in the field of sewage treatment equipment technology, among which the invention patent with publication number CN118512910A discloses an ultrafiltration membrane sewage guiding and filtering assembly, including a bracket, a plurality of tank bodies are fixedly connected to the bracket, plugs are installed at both ends of the tank body, an ultrafiltration membrane is fixedly connected between the two plugs, a tank cover is fixedly connected to both ends of the tank body, a plurality of water inlet pipes are evenly arranged on the tank body, a plurality of water inlet pipes are fixedly connected to water guide pipes, a plurality of water guide pipes are fixedly connected to the ends of the water guide pipes, and a discharge pipe is fixedly connected to the bottom of the tank body. The above arrangement is relied on to improve the uniformity of sewage entering the tank body. The technical solution is provided with a plurality of water inlet pipes, wire guide pipes and water supply pipes. When in use, , relying on the above-mentioned arrangement, the sewage is distributed to multiple water inlets, so as to improve the uniformity of sewage entering the tank body, thereby reducing the situation where the filtration load in the local area of ​​the ultrafiltration membrane is too large, thereby reducing the impact on the filtration. This technical solution still has some shortcomings in the process of application. The sewage enters the tank body from multiple water inlet pipes, so as to improve the uniformity of sewage entering the tank body, but the position where the sewage enters the tank body is in a relatively static state with the ultrafiltration membrane. The sewage directly acts vertically on the ultrafiltration membrane, which is still easy to cause local blockage of the ultrafiltration membrane. The ultrasonic transducer technology is introduced, and the ultrafiltration membrane is cleaned by ultrasonic vibration, which increases the production cost of the ultrafiltration membrane sewage guiding filtration component, makes the structure more complicated, and is not practical.

[0004] Based on this, the present invention designs an ultrafiltration membrane sewage guiding filtration component to solve the above problems. Summary of the invention

[0044] The specific implementation method is as follows: the gear shaft 5062 drives the threaded rod 303 to move synchronously during the forward and reverse motion. The rotation of the threaded rod 303 will cause the threaded cylinder 302 to be displaced. The displacement of the threaded cylinder 302 is used to drive the middle cylinder to move through the transmission seat 301. Since the gear shaft 5062 automatically performs forward and reverse motion, the two ends of the middle cylinder will drive the piston ring A1046 and the piston ring B1047 to perform piston motion in the piston groove A1032 and the piston groove B1034 respectively.

[0045] Specifically, the drainage mechanism 4 includes a cache tank 401, the side end face of the cache tank 401 is connected to a rear support seat 402, the side end face of the cache tank 401 corresponds to the inner side of the rear support seat 402 and is connected to a sewage pipe A403, the cache tank 401 is connected to another support frame 101 through the rear support seat 402, the other end of the cache tank 401 is sealed and connected to a tank cover C404, the outer surface of the cache tank 401 is connected to a sewage pipe B405 near the tank cover C404, the other end of the sewage pipe B405 is connected to the inlet pipe 1048, the inner end face of the tank cover C404 is clamped with a sealing sleeve 406, the power conversion mechanism 5 includes a water wheel 501 rotatably connected to the cache tank 401, the side end face of the water wheel 501 is connected to a transmission shaft 502, the transmission shaft 5 The other end of 02 is connected to a wheel ring 503, and an arc-shaped tooth plate 504 is connected to the inner ring surface of the wheel ring 503.

After the arc-shaped tooth plate 504 is disengaged from the driven gear 5061, the fan gear 505 is in meshing relationship with the driven gear 5061, and the fan gear 505 will drive the driven gear 5061 to rotate in another direction, thereby being able to drive the gear shaft 5062 to automatically perform forward and reverse movements.

[0047] Working principle, when using:

[0048] The sewage to be treated is introduced into the sewage pipe A403. After the sewage enters the buffer tank 401 through the sewage pipe A403, it drives the water wheel 501 to rotate rapidly. During the rotational motion, the water wheel 501 drives the wheel ring 503 to rotate through the transmission shaft 502, and the wheel ring 503 drives the arc gear plate 504 and the fan gear 505 to rotate synchronously and move relative to the driven gear 5061. When the arc gear plate 504 in the rotating state is in meshing relationship with the driven gear 5061, the arc gear plate 504 will drive the driven gear 5061 to rotate in one direction on the gear frame 5063 through the gear shaft 5062. After the arc gear plate 504 is disengaged from the driven gear 5061, the fan gear 505 is in meshing relationship with the driven gear 5061, and the fan gear 505 will drive the driven gear 5061 to rotate in the other direction, thereby being able to drive the gear shaft 5062 to automatically perform forward and reverse motions.

[0049] The gear shaft 5062 drives the threaded rod 303 to move synchronously during the forward and reverse motion. The rotation of the threaded rod 303 will cause the threaded cylinder 302 to be displaced, and the displacement of the threaded cylinder 302 is used to drive the middle cylinder to move through the transmission seat 301. Since the gear shaft 5062 automatically performs forward and reverse motions, the two ends of the middle cylinder will drive the piston ring A1046 and the piston ring B1047 to perform piston motion in the piston groove A1032 and the piston groove B1034 respectively. The piston ring A1046 and the piston ring B1047 perform piston motion in the piston groove A1032 and the piston groove B1034 respectively. The inner wall pressure of the piston groove A1032 and the piston groove B1034 will change. When the internal pressure of the piston groove A1032 decreases, the internal pressure of the piston groove B1034 increases. At this time, the single The one-way valve A1 is opened, and the piston groove A1032 uses the degassing membrane A to extract the gas in the filtered water to the tank cover A1035 through the suction pipe A201, and the one-way valve B2 on the exhaust pipe B204 is opened. The gas in the piston groove B1034 enters the inlet pipe 1048 through the exhaust pipe B204. When the internal pressure of the piston groove A1032 increases, the internal pressure in the piston groove B1034 decreases. At this time, the one-way valve A1 on the suction pipe A201 is closed, the one-way valve A2 on the exhaust pipe A203 is opened, the one-way valve on the suction pipe B202 is opened, the one-way valve B2 on the exhaust pipe B204 is closed, and the piston groove B1034 uses the degassing membrane B to extract the gas in the filtered water to the tank cover B1036 through the suction pipe A201, and the gas in the piston groove A1032 enters the inlet pipe 1048 through the exhaust pipe A203.
