Description

Technical Field

[0001] This utility model relates to the field of ultrafiltration membrane filtration technology, specifically to a deep water purification ultrafiltration membrane filtration device. Background Technology

[0002] Ultrafiltration is a pressure-driven membrane separation technology. Under certain pressure, small molecule solutes and solvents are forced to pass through a specially designed membrane with a specific pore size, while large molecule solutes cannot pass through and remain on one side of the membrane. This process partially purifies the large molecules. The principle of ultrafiltration is also a membrane separation process. Ultrafiltration uses a pressure-activated membrane to retain colloids, particles, and substances with relatively high molecular weights in water under external driving force (pressure), while water and small solute particles pass through the membrane.

[0003] In the prior art, such as the deep water purification ultrafiltration membrane filtration device disclosed in Chinese Patent No. CN220265516U, there are three filtration chambers arranged laterally: a first filtration chamber, a second filtration chamber, and a third filtration chamber. Each of the three filtration chambers contains an ultrafiltration membrane tube. Multiple micropores are formed through the outer wall of the ultrafiltration membrane tube, and a membrane cavity is formed inside the ultrafiltration membrane tube. A cavity is formed between the outer wall of the ultrafiltration membrane tube and the inner walls of the first, second, and third filtration chambers. Wastewater within the cavity is simultaneously filtered through the three ultrafiltration membrane tubes. Water molecules flow into the membrane cavity, while microorganisms, suspended particles, and colloids are trapped on the outer wall of the ultrafiltration membrane tube, thus achieving the effect of wastewater filtration and purification. Furthermore, the filtered water allows the adsorption cylinder to adsorb and filter wastewater while rotating. The filtered water flows into the filter box and is filtered through the activated carbon adsorption plate and filter elements, thereby achieving the effect of wastewater filtration and purification.

[0004] While the aforementioned patents can filter and purify wastewater, some problems still exist. The fixed position of the cavity for wastewater means that the wastewater passes through the ultrafiltration membrane tube from one side, resulting in uneven distribution of pollutants on the membrane surface. Some areas are prone to rapid accumulation of dirt, which affects the overall filtration efficiency. In addition, the filter screen is prone to clogging due to the filtration of wastewater impurities. Therefore, this utility model provides a deep water purification ultrafiltration membrane filtration device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a deep water purification ultrafiltration membrane filtration device, which solves the problems of uneven distribution of pollutants on the membrane surface, rapid accumulation of dirt in some areas, which affects the overall filtration efficiency and the filtration of wastewater impurities by the filter screen, and easily leads to material clogging of the filter screen.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: it includes an impurity filtration mechanism, which is used to filter impurity particles in sewage, and a multi-layer filtration mechanism is provided on one side of the outer wall of the impurity filtration mechanism for multi-layer filtration of sewage.

[0007] The multi-layer filtration mechanism includes a second filter cartridge, a top cover fixedly installed at the top of the second filter cartridge, a rotating connecting pipe rotatably installed at the top of the top cover, an external gear ring fixedly sleeved on the outer wall of the rotating connecting pipe, the output end of the rotating connecting pipe passing through the top of the top cover and fixedly connected to an ultrafiltration membrane tube, a rotary joint fixedly connected at the top of the rotating connecting pipe, a first connecting pipe fixedly connected at the top of the rotary joint, an L-shaped plate fixedly installed at the top of the top cover, a motor fixedly installed at the top of the L-shaped plate, the output end of the motor passing through the top of the L-shaped plate and fixedly installed with an incomplete gear, the incomplete gear meshing with the external gear ring;

[0008] The impurity filtration mechanism includes a first filter cylinder, the top of which has two slots. Each slot has a movably inserted block on its inner wall, and a filter screen is fixedly installed between the opposite sides of the two blocks.

[0009] Preferably, a support frame is fixedly installed on the inner wall of the filter screen cylinder, a rotating rod is rotatably installed on the top of the support frame, and the bottom end of the rotating rod passes through the top of the support frame and is fixedly installed with a connecting rod.

[0010] Preferably, a spiral scraper is fixedly installed at one end of the outer wall of the connecting rod, the spiral scraper is fitted to the inner wall of the filter screen cylinder, and three fan blades are fixedly installed at the top end of the rotating rod.

[0011] Preferably, the top end of the first filter cylinder is threadedly connected to a screw cap, the top end of the screw cap is fixedly connected to a liquid inlet pipe, the bottom end of the first filter cylinder is fixedly connected to a threaded connecting pipe, and the outer wall of the threaded connecting pipe is threadedly connected to a collection cap.

[0012] Preferably, the multi-layer filtration mechanism further includes a third filter cylinder, the inner wall of which is provided with a set of activated carbon filter plates, the bottom end of which is fixedly connected to a liquid outlet valve, and the top end of which is fixedly connected to one end of the first connecting pipe.

[0013] Preferably, a second connecting pipe is fixedly connected to one end of the outer wall of the first filter cylinder, and the end of the second connecting pipe away from the first filter cylinder is fixedly connected to the second filter cylinder.

[0014] Beneficial effects

[0015] This invention provides a deep water purification ultrafiltration membrane filtration device. Compared with the prior art, it has the following advantages:

[0016] (1) When the ultrafiltration membrane tube filters sewage, in order to prevent uneven distribution of pollutants on the membrane surface, the motor can be turned on. The motor drives the incomplete gear to rotate, which in turn drives the outer gear ring to rotate. The outer gear ring then drives the rotating connecting pipe and the ultrafiltration membrane tube to rotate. The rotation of the ultrafiltration membrane tube can make the water flow and the membrane surface more uniform, avoiding excessive accumulation of pollutants in local areas, thereby improving the overall filtration efficiency. At the same time, due to the incomplete gear, the ultrafiltration membrane tube can rotate intermittently, so that the ultrafiltration membrane tube has a short pause after rotating for a period of time, allowing impurities in the sewage to have more time to contact the surface of the ultrafiltration membrane tube and be filtered, thus improving the filtration accuracy.

[0017] (2) When the wastewater impurities need to be filtered, the wastewater is introduced into the filter cylinder through the inlet pipe. The wastewater passes through the inner wall of the filter cylinder, while the impurities remain in the inner wall of the filter cylinder. Since there are fan blades and rotating rods, when the water flows from top to bottom through the fan blades, it will drive the fan blades and rotating rods to rotate. When the rotating rods rotate, they will drive the connecting rods to rotate. The connecting rods can then drive the spiral scraper to rotate on the inner wall of the filter cylinder. Due to the special shape of the spiral scraper, the spiral scraper can scrape off the impurities attached to the inside of the filter cylinder during the rotation process and push them into the collection cover below for easy collection of impurities.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides two technical solutions:

[0028] Figures 1-7 The first embodiment is shown: a deep water purification ultrafiltration membrane filtration device, including an impurity filtration mechanism 1, which is used to filter impurity particles in sewage, and a multi-layer filtration mechanism 2 is provided on one side of the outer wall of the impurity filtration mechanism 1 for multi-layer filtration of sewage.

[0029] The multi-layer filtration mechanism 2 includes a second filter cartridge 201. A top cover 202 is fixedly installed at the top of the second filter cartridge 201. A rotating connecting pipe 206 is rotatably installed at the top of the top cover 202. An external toothed ring 207 is fixedly sleeved on the outer wall of the rotating connecting pipe 206. The output end of the rotating connecting pipe 206 passes through the top of the top cover 202 and is fixedly connected to an ultrafiltration membrane tube 208. When water flows over the surface of the ultrafiltration membrane tube 208, water molecules can pass through the inner wall of the ultrafiltration membrane tube 208, while microorganisms, suspended particles, bacteria, viruses, and colloids are trapped on the outer wall of the ultrafiltration membrane tube 208. A rotary joint 209 is fixedly connected at the top of the rotating connecting pipe 206. A first connecting pipe 210 is fixedly connected at the top of the rotary joint 209. The rotary joint 209 is existing technology and allows liquid to flow between the first connecting pipe 210 and the rotating connecting pipe 206. The body allows the rotating connecting pipe 206 to rotate. An L-shaped plate 203 is fixedly installed on the top of the top cover 202. A motor 204 is fixedly installed on the top of the L-shaped plate 203. The output end of the motor 204 passes through the top of the L-shaped plate 203 and is fixedly installed with an incomplete gear 205. The incomplete gear 205 meshes with the external gear ring 207. The motor 204 drives the incomplete gear 205 to rotate, which in turn drives the external gear ring 207 to rotate. The external gear ring 207 then drives the rotating connecting pipe 206 and the ultrafiltration membrane tube 208 to rotate. The rotation of the ultrafiltration membrane tube 208 can make the water flow and the membrane surface more uniform, avoiding excessive accumulation of pollutants in local areas, thereby improving the overall filtration efficiency. Due to the incomplete gear 205, the ultrafiltration membrane tube 208 can rotate intermittently.

[0030] The impurity filtration mechanism 1 includes a first filter cylinder 101. Two slots 102 are provided at the top of the first filter cylinder 101. A locking block 104 is movably inserted into the inner wall of each of the two slots 102. A filter screen cylinder 103 is fixedly installed between the opposite sides of the two locking blocks 104. The slots 102 are designed to facilitate the fixing of the locking blocks 104 and also facilitate the removal of the filter screen cylinder 103 from the first filter cylinder 101.

[0031] Figures 1-7The second embodiment is shown, and its main difference from the first embodiment is that: a support frame 105 is fixedly installed on the inner wall of the filter cylinder 103, a rotating rod 106 is rotatably installed on the top of the support frame 105, the bottom end of the rotating rod 106 passes through the top of the support frame 105, and a connecting rod 108 is fixedly installed thereon. A spiral scraper 109 is fixedly installed on one end of the outer wall of the connecting rod 108. The spiral scraper 109 is fitted against the inner wall of the filter cylinder 103. Three fan blades 107 are fixedly installed on the top of the rotating rod 106. When water flows from top to bottom through the fan blades 107, it will drive the fan blades 107 and the rotating rod 106 to rotate. When the rotating rod 106 rotates, it will drive the connecting rod 108 to rotate. The connecting rod 108 can thus drive the spiral scraper 109 to rotate within the filter cylinder 103. The spiral scraper 109 rotates on the wall. Due to its special shape, it can scrape off impurities attached to the inside of the filter cylinder 103 during rotation and push them into the collection cover 110 below for easy collection. The top of the first filter cylinder 101 is threadedly connected to a cap 111, which can be easily removed from the top of the first filter cylinder 101. The top of the cap 111 is fixedly connected to an inlet pipe 112, and the bottom of the first filter cylinder 101 is fixedly connected to a threaded connecting pipe 113. The outer wall of the threaded connecting pipe 113 is threadedly connected to a collection cover 110, which can be easily removed from the threaded connecting pipe 113. To improve the sealing performance of the collection cover 110 and the threaded connecting pipe 113, a sealing gasket or other structure to improve the sealing performance can be provided.

[0032] The multi-layer filtration mechanism 2 also includes a third filter cylinder 211. The inner wall of the third filter cylinder 211 is provided with a set of activated carbon filter plates 212, which can adsorb odors and heavy metal ions in the sewage. The bottom end of the third filter cylinder 211 is fixedly connected to an outlet valve 213, which facilitates the discharge of filtered and purified sewage from the third filter cylinder 211. The top end of the third filter cylinder 211 is fixedly connected to one end of the first connecting pipe 210.

[0033] One end of the outer wall of the first filter cylinder 101 is fixedly connected to a second connecting pipe 215, and the end of the second connecting pipe 215 away from the first filter cylinder 101 is fixedly connected to the second filter cylinder 201.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, when wastewater impurities need to be filtered, wastewater is introduced into the filter cylinder 103 through the inlet pipe 112. The wastewater passes through the inner wall of the filter cylinder 103, while impurities remain on the inner wall. Because of the fan blades 107 and rotating rod 106, when water flows down through the fan blades 107, it drives the fan blades 107 and rotating rod 106 to rotate. The rotating rod 106, in turn, drives the connecting rod 108 to rotate, which in turn drives the spiral scraper 109 to rotate on the inner wall of the filter cylinder 103. Due to the special shape of the spiral scraper 109, it can scrape off impurities adhering to the inside of the filter cylinder 103 during rotation and push them into the collection cover 110 below for easy collection. Wastewater from the filter cylinder 103 enters the second filter cylinder 201 through the second connecting pipe 215. When water flows through the ultrafiltration membrane... When water molecules pass through the inner wall of the ultrafiltration membrane tube 208, microorganisms, suspended particles, bacteria, viruses, and colloids are trapped on the outer wall of the ultrafiltration membrane tube 208. To prevent uneven distribution of pollutants on the membrane surface, the motor 204 can be activated. The motor 204 drives the incomplete gear 205 to rotate, which in turn drives the outer gear ring 207 to rotate. The outer gear ring 207 then drives the rotating connecting tube 206 and the ultrafiltration membrane tube 208 to rotate. The rotation of the ultrafiltration membrane tube 208 makes the contact between the water flow and the membrane surface more uniform, avoiding excessive accumulation of pollutants in local areas, thereby improving the overall filtration efficiency. Furthermore, the incomplete gear 205 allows the ultrafiltration membrane tube 208 to rotate intermittently, with brief pauses after a period of rotation. This allows impurities in the wastewater more time to contact and be filtered from the surface of the ultrafiltration membrane tube 208, improving the filtration precision. After filtration, the water can be connected to the third filter cylinder 211 through the first connecting pipe 210. The third filter cylinder 211 is equipped with a set of activated carbon filter plates 212, which can adsorb odors and heavy metal ions in the sewage. Through multiple filtrations, the purification effect of the sewage is improved. The treated sewage can be discharged through the outlet valve 213.
