Description

Technical Field

[0001] This utility model belongs to the technical field of sewage treatment devices, specifically relating to a ceramic membrane filtration deep treatment device. Background Technology

[0002] The ceramic membrane filtration deep treatment device is a device used for deep filtration and treatment of liquids. It mainly consists of a ceramic membrane module, a filtration system, a cleaning system, and a control system. The vacuum pump creates a negative pressure inside the ceramic membrane module through the filtration pipe, causing the liquid to be treated to pass through the ceramic membrane under the action of the pressure difference, while impurities are trapped on the membrane surface, thereby achieving filtration and separation.

[0003] Patent document CN215822534U discloses a ceramic membrane filtration device, comprising: a connecting pipe having an inlet and an outlet; a filtration mechanism connecting the inlet and outlet, wherein liquid enters the filtration mechanism from the inlet and is filtered, and the filtered liquid flows out from the outlet; and a storage mechanism connected to the outlet, into which the filtered liquid enters. The storage mechanism includes a storage tank and a pipe connected to the storage tank, with a viewing window on the pipe. By including the storage mechanism, which comprises a storage tank and a pipe connecting the storage tank and the filtration mechanism, and a viewing window on the pipe, the operator can determine the degree of filtration of the liquid in the pipe through the viewing window, thus facilitating further operation.

[0004] The aforementioned device allows staff to assess the filtration level of the liquid within the pipes through a viewing window, facilitating further operations. However, when using this device, the core filtration components are easily clogged by various pollutants during wastewater treatment. This not only drastically reduces filtration efficiency but also requires prolonged equipment shutdown for cleaning, severely disrupting production efficiency and significantly impacting the continuity of wastewater treatment. Therefore, a novel ceramic membrane filtration deep treatment device is needed to improve upon the aforementioned device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a ceramic membrane filtration deep treatment device. Through the cooperation of the backwashing component and the sealing component, it effectively prevents the diffusion of impurities into the surrounding environment during backwashing, avoids secondary pollution, and creates a clean and safe environment for equipment operation. It solves the problem that existing filter components are easily attached and clogged by various pollutants during wastewater treatment. This situation not only drastically reduces filtration efficiency, but also requires the equipment to be shut down for a long time during cleaning, which seriously interferes with production efficiency and greatly affects the continuity of wastewater treatment.

[0006] To achieve the above-mentioned purpose of effectively preventing the diffusion of impurities into the surrounding environment during backwashing through the cooperation of the anti-cleaning component and the sealing component, avoiding secondary pollution, and creating a clean and safe environment for equipment operation, this utility model provides the following technical solution: a ceramic membrane filtration deep treatment device, including a water treatment component, a sealing component at the inner end of the water treatment component, an auxiliary component at the inner end of the sealing component, and an anti-cleaning component on one side of the sealing component;

[0007] The water treatment component includes a sewage tank, with a limiting frame fixedly connected to the inner end of the sewage tank, and a ceramic membrane plate installed between the upper and lower inner walls of the limiting frame.

[0008] The sealing assembly includes a corrugated sleeve fixedly connected to the inner wall of the limiting frame. The lower end of the corrugated sleeve is fixedly connected to an outer fence hollow plate. Side connecting blocks are symmetrically fixedly connected to the left and right ends of the outer fence hollow plate. Electric push rods are symmetrically fixedly connected to the left and right sides of the upper inner wall of the limiting frame. The output end of the electric push rod is connected to the corresponding side connecting block.

[0009] Furthermore, a water pump is fixedly connected to the upper right side of the limiting frame, and a water pump is connected to the outside of the water pump.

[0010] Furthermore, the anti-cleaning components include a pump located on the left side of the wastewater tank.

[0011] Furthermore, the pump's output end is connected to a backflow pipe, which is connected to the upper left side of the limiting frame.

[0012] Furthermore, the auxiliary components include an inner wall opening water outlet groove formed on the inner wall of the limiting frame, and a spring is fixedly connected to the inner end of the inner wall opening water outlet groove.

[0013] Furthermore, the upper end of the spring is fixedly connected to a sealing block that slides within the water outlet groove with an opening in the inner wall, and the front end of the hollow panel of the outer fence is fixedly connected to a linkage protruding rod.

[0014] Furthermore, the linkage protruding rod and the sealing pressure block are in contact with each other, and a water collection tank is fixedly connected to the lower end of the sewage tank, and a water guide pipe is fixedly connected to the lower end of the water collection tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. When this utility model is in use, the anti-cleaning component and the sealing component work together, and the two electric push rods are started synchronously to push the hollow outer fence plate to slide smoothly down along the outer wall of the limiting frame. The corrugated sleeve connected to the upper end of the hollow outer fence plate is stretched until it completely covers the ceramic membrane plate, creating a relatively sealed space. This effectively prevents impurities from spreading to the surrounding environment during the backwashing process, avoids secondary pollution, and creates a clean and safe environment for equipment operation.

[0017] 2. When this utility model is in use, by setting an auxiliary component, during the backwashing operation, the linkage protruding rod fixed at the front end of the hollow plate of the outer fence moves down synchronously, precisely squeezing the sealing block, exposing the water filtration position of the water outlet groove with openings on the inner wall. The wastewater containing impurities generated during backwashing can flow smoothly into the water collection tank through this channel, and then be discharged and treated through the water guide pipe. This design realizes the backwashing self-cleaning of the ceramic membrane plate without stopping the equipment, ensuring the continuity of equipment operation, without interrupting the work process due to cleaning and maintenance, significantly improving the overall work efficiency and reducing the economic losses caused by downtime.

Detailed Implementation

[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] Please see Figures 1 to 5 This utility model provides a technical solution: a ceramic membrane filtration deep treatment device, including a water treatment component 1, a sealing component 2 is provided at the inner end of the water treatment component 1, an auxiliary component 3 is provided at the inner end of the sealing component 2, and a back-cleaning component 4 is provided on one side of the sealing component 2.

[0028] The water treatment component 1 includes a sewage tank 100, with a limiting frame 101 fixedly connected to the inner end of the sewage tank 100, and a ceramic membrane plate 102 installed between the upper and lower inner walls of the limiting frame 101.

[0029] The sealing assembly 2 includes a corrugated sleeve 201 fixedly connected to the inner wall of the limiting frame 101. The lower end of the corrugated sleeve 201 is fixedly connected to an outer fence hollow plate 202. Side connecting blocks 203 are symmetrically fixedly connected to the left and right ends of the outer fence hollow plate 202. Electric push rods 204 are symmetrically fixedly connected to the left and right sides of the upper inner wall of the limiting frame 101. The output end of the electric push rod 204 is connected to the corresponding side connecting block 203.

[0030] like Figure 3-5 As shown, a water pumping pipe 103 is fixedly connected to the upper right side of the limiting frame 101, and a water pump 104 is connected to the outside of the water pumping pipe 103. The back cleaning component 4 includes a pump 400, which is located on the left side of the sewage tank 100. The output end of the pump 400 is connected to a backflow pipe 401, and the backflow pipe 401 and the upper left side of the limiting frame 101 are interconnected.

[0031] It should be noted that, through the cooperation of the back-cleaning component 4 and the sealing component, the two electric push rods 204 are started synchronously, pushing the outer fence hollow plate 202 to slide smoothly down along the outer wall of the limiting frame 101. The corrugated sleeve 201 connected to the upper end of the outer fence hollow plate 202 is stretched until it completely covers the ceramic membrane plate 102, creating a relatively sealed space. This effectively prevents impurities from spreading to the surrounding environment during the backwashing process, avoids secondary pollution, and creates a clean and safe environment for equipment operation.

[0032] like Figure 1 , Figure 3-5 As shown, the auxiliary component 3 includes an inner wall opening water outlet groove 302 formed on the inner wall of the limiting frame 101. A spring 304 is fixedly connected to the inner end of the inner wall opening water outlet groove 302. A sealing pressure block 303 that is slidably connected in the inner wall opening water outlet groove 302 is fixedly connected to the upper end of the spring 304. A linkage protrusion rod 301 is fixedly connected to the front end of the outer fence hollow plate 202. The linkage protrusion rod 301 and the sealing pressure block 303 are in contact with each other. A water collection tank 305 is fixedly connected to the lower end of the sewage tank 100. A water guide pipe 306 is fixedly connected to the lower end of the water collection tank 305.

[0033] It should be noted that by setting auxiliary components during backwashing, the linkage protruding rod 301 fixed at the front end of the outer fence hollow plate 202 moves down synchronously, precisely squeezing the sealing block 303, exposing the water filtration position of the inner wall opening water outlet trough 302. The wastewater containing impurities generated during backwashing can flow smoothly into the water collection tank 305 through this channel, and then be discharged and treated through the water guide pipe 306. This design realizes the self-cleaning of the ceramic membrane plate 102 by backwashing without stopping the equipment, ensuring the continuity of equipment operation, without interrupting the work process due to cleaning and maintenance, significantly improving the overall work efficiency, and reducing the economic losses caused by downtime.

[0034] The working principle of the above embodiment is as follows: In this ceramic membrane filtration deep treatment device, sewage first flows into the sewage tank 100. After the pump 104 is started, the suction force generated by it acts on the ceramic membrane plate 102 in the limiting frame 101 through the pumping pipe 103. Driven by the pressure difference, the sewage passes through the micropores of the ceramic membrane plate 102, while impurities, such as suspended particles, colloids, and large molecular organic matter, are intercepted by the ceramic membrane plate 102. The purified water filtered by the ceramic membrane plate 102 is extracted through the pumping pipe 103 and transported to the subsequent treatment stage or directly reused, thereby achieving the initial purification of sewage. As the treatment process continues, impurities gradually accumulate on the surface of the ceramic membrane plate 102, affecting its filtration effect. At this time, the backwashing component 4 is activated. After the pump 400 is turned on, cleaning water is transported to the ceramic membrane plate 102 through the backwash pipe 401 to backwash the ceramic membrane plate 102. Under pressure, the cleaning water flows from the clean water side to the wastewater side of the ceramic membrane plate 102, washing away the impurities attached to the surface and micropores of the ceramic membrane plate 102, achieving the purpose of self-cleaning and ensuring the continuous and stable filtration performance of the ceramic membrane plate 102. When the backwashing component 4 starts running, to prevent impurities from overflowing during the backwashing process, two... The electric push rods 204 are activated synchronously. The output end of the electric push rod 204 pushes the side connecting block 203, causing the outer fence hollow plate 202 to slide downward along the outer wall of the limiting frame 101. During this process, the corrugated sleeve 201 connected to the upper end of the outer fence hollow plate 202 is gradually stretched until it completely covers the ceramic membrane plate 102, forming a relatively sealed space around the ceramic membrane plate 102. At the same time, the linkage protrusion 301 fixed at the front end of the outer fence hollow plate 202 moves downward. When the linkage protrusion 301 contacts the sealing pressure block 303, the continuing downward movement of the linkage protrusion 301... The sealing block 303 applies pressure, compressing the spring 304 below, causing the sealing block 303 to slide downwards within the water outlet groove 302 with openings in the inner wall. As the sealing block 303 moves downwards, the filter water position in the water outlet groove 302 with openings in the inner wall is exposed. Wastewater containing impurities generated during the backwashing process flows into the water collection tank 305 through the exposed water outlet groove 302 with openings in the inner wall, and is then discharged through the water guide pipe 306 and transported to a special treatment facility for further treatment. With this design, the device can achieve backwashing self-cleaning operation of the ceramic membrane plate 102 without stopping operation, ensuring continuous and efficient operation of the equipment.

[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
