Description

Technical Field

[0001] This utility model relates to the field of wastewater filtration and treatment technology, and in particular to a ceramic membrane filtration device. Background Technology

[0002] Inorganic ceramic membrane filtration devices are commonly used in wastewater treatment systems. Small water molecules pass through the ceramic membrane and are separated from impurities on the other side, thus achieving wastewater filtration. Ceramic membrane filtration devices have advantages such as high strength, high temperature resistance, corrosion resistance, and good filtration effect, and are widely used in wastewater filtration.

[0003] Existing ceramic membrane filtration devices typically consist of a housing and a filter element. The filter element is installed inside the housing, which has an inlet and an outlet, and a sludge discharge port at the bottom. Because wastewater contains many impurities, these impurities tend to accumulate at the bottom of the housing, easily clogging the inorganic ceramic membrane filter element or the sludge discharge port, thus affecting the normal operation of the filtration device. Utility Model Content

[0004] The purpose of this invention is to provide a ceramic membrane filtration device that facilitates the discharge of impurities from the bottom, which is beneficial for the stable use of the ceramic membrane filtration device.

The rotating shaft is rotatably arranged along the central axis of the housing. The scraper is connected to the rotating shaft and fits into the inner wall of the bottom of the housing.

[0008] Furthermore, the rotary input component includes an input shaft, the rotary shaft is connected to a first bevel gear, the input shaft is connected to a second bevel gear meshing with the first bevel gear, and the input shaft passes through the housing and protrudes outside the housing.

[0009] Furthermore, the bottom of the housing is provided with a mounting hole, and a mounting sleeve is provided in the mounting hole, through which the input shaft passes; an annular groove is provided on the periphery of the input shaft, and a sealing ring is nested in the annular groove, the sealing ring abutting against the inner wall of the mounting sleeve.

[0010] Furthermore, a rotating bracket is connected to the bottom of the mounting bracket. The rotating bracket includes a support rod and a support ring. The rotating shaft is rotatably inserted through the support ring, and the support rod is connected between the support ring and the mounting bracket.

[0011] Furthermore, a ring-shaped limiting groove is provided around the circumference of the rotating shaft, and the support ring is fitted into the limiting groove.

[0012] Furthermore, the mounting bracket includes a first mounting plate and a second mounting plate. The first mounting plate is mounted on the upper inner wall of the housing and encloses the upper part of the housing to form an upper chamber. The second mounting plate is mounted on the lower part of the housing and encloses the lower inner wall of the housing to form a lower chamber. A clear water chamber is formed between the first mounting plate and the second mounting plate. The water inlet is connected to the lower chamber, the clear water outlet is connected to the clear water chamber, the wastewater outlet is connected to the upper chamber, and both ends of the ceramic membrane filter tube are connected to the upper chamber and the lower chamber, respectively.

[0013] Furthermore, a water inlet pipe is provided at the bottom of the lower chamber, and the water inlet pipe is connected to the sewage source; the water inlet pipe is connected to the water inlet, and the end of the water inlet pipe away from the water inlet forms the slag discharge port, and a slag discharge valve is provided at the slag discharge port.

[0014] Furthermore, the inlet pipe includes a vertical pipe section, a horizontal pipe section, and a sewage connection pipe section; the vertical pipe section is connected to the inlet at the bottom of the outer casing, and the end of the vertical pipe section away from the inlet forms the sludge discharge port; the horizontal pipe section is connected to the vertical pipe section, and the sewage connection pipe section is connected to the sewage source;

[0015] The sewage outlet is connected to a drain pipe, and the drain pipe is connected to the horizontal pipe section; a first shut-off valve is installed on the horizontal pipe section, and the first shut-off valve is located between the drain pipe and the inlet pipe.

[0016] Furthermore, the scraper is an arc-shaped plate.

[0017] Furthermore, a handwheel is connected to the portion of the input shaft that extends beyond the housing.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. In the ceramic membrane filtration device of this utility model, the wastewater to be treated enters the outer shell through the inlet. After the wastewater flows through the ceramic membrane filter tube on the mounting bracket, the filtered clean water obtained after water permeates through the ceramic membrane filter tube is discharged from the clean water outlet, and the wastewater left in the ceramic membrane filter tube flows out from the wastewater outlet, thus achieving wastewater filtration. A scraping assembly is installed inside the bottom of the outer shell. This assembly drives a rotating shaft to rotate via a rotating output component. The rotating shaft then drives a scraper plate to rotate along the inner wall of the bottom of the outer shell, scraping off the deposited impurities inside the bottom wall of the outer shell. This allows the impurities to be smoothly discharged from the slag discharge port, preventing the accumulation of impurities at the bottom of the outer shell from clogging the ceramic membrane filter tube or the slag discharge port, and facilitating the normal operation of the ceramic membrane filtration device.

[0020] 2. The input shaft and the rotating shaft are driven by the meshing of the first bevel gear and the second bevel gear, so that when the rotating shaft is rotating around the central axis of the housing, the input shaft can be set perpendicular to the rotating shaft and pass through the housing. This allows the input shaft to avoid the filter element assembly in the middle of the housing and avoids interference between the input shaft and the filter element assembly.

[0021] 3. In this utility model, a water inlet pipe is provided at the bottom of the lower chamber. The water inlet pipe is connected to a sewage source to introduce sewage into the outer shell for filtration. At the same time, the water inlet pipe forms a slag discharge port. When the sewage source is connected to the outer shell, the slag discharge valve is closed, and sewage can enter the outer shell from the water inlet pipe. When the sewage source is turned off, impurities at the bottom of the outer shell can enter the water inlet pipe from the water inlet. At this time, the slag discharge valve is opened, and the impurities can be discharged from the slag discharge port. Thus, only one water inlet pipe needs to be provided at the bottom of the outer shell to realize the slag discharge and water intake of the shell, reducing the number of interfaces, lowering the sealing requirements of the outer shell, and reducing production costs.

[0022] 4. The inlet pipe includes a vertical section, a horizontal section, and a sewage connection section. The sewage outlet is connected to the horizontal section via a drain pipe. Therefore, when the first shut-off valve is opened, sewage from the source can enter the casing through the sewage connection section, the horizontal section, and the vertical section. The sewage filtered by the casing flows back to the horizontal section from the sewage outlet and the drain pipe, mixing with the sewage from the sewage connection section before continuing to be filtered in the casing, improving the filtration effect. Simultaneously, when the first shut-off valve is closed, water from the sewage connection section enters the upper chamber from the horizontal section and the drain pipe, and flows downwards through the ceramic membrane filter tube to flush the ceramic membrane filter tube and the lower chamber. Opening the sludge discharge valve allows the flushed water and impurities to be discharged, thus cleaning the ceramic membrane filter device. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] This embodiment discloses a ceramic membrane filtration device 1000, referencing... Figure 1 and Figure 2 The ceramic membrane filtration device 1000 includes a filter element assembly 200 and a housing 100, with the filter element assembly 200 installed inside the housing 100. The housing 100 is provided with an inlet 110, a clean water outlet 120, and a wastewater outlet 130. When using the ceramic membrane filtration device 1000, wastewater from the wastewater source flows into the housing 100 through the inlet 110, flows through the filter element assembly, and the filtered clean water flows out through the clean water outlet 120. The remaining wastewater, rich in impurities, flows out through the wastewater outlet 130.

[0031] Reference Figure 2The filter assembly 200 includes a ceramic membrane filter tube 210 and a mounting bracket 220. The mounting bracket 220 is detachably fixed inside the housing 100, and the ceramic membrane filter tube 210 is fixed to the mounting bracket 220 parallel to the circumference of the housing 100. The ceramic membrane filter tube 210 is a common tubular ceramic membrane with multiple through holes arranged axially at both ends. When sewage flows through the through holes of the ceramic membrane filter tube 210, water molecules can permeate to the outside of the ceramic membrane filter tube 210, while large molecular impurities remain inside the through holes and flow with the sewage, thereby achieving sewage filtration.

[0032] The mounting bracket 220 includes a first mounting plate 221 and a second mounting plate 222. The first mounting plate 221 and the second mounting plate 222 are arranged parallel to each other. The first mounting plate 221 is mounted on the upper inner wall of the outer casing 100 and encloses the upper part of the outer casing 100 to form an upper chamber 140. The second mounting plate 222 is mounted on the lower part of the outer casing 100 and encloses the lower inner wall of the outer casing 100 to form a lower chamber 150. The first mounting plate 221 and the second mounting plate 222 enclose a clear water chamber 160. The water inlet 110 is located at the bottom of the outer casing 100 and communicates with the lower chamber 150. The clear water outlet 120 is located in the upper middle part of the outer casing 100 and communicates with the clear water chamber 160. The wastewater outlet 130 is located in the upper part of the outer casing 100 and communicates with the upper chamber 140. The two ends of the ceramic membrane filter tube 210 are respectively connected to the upper chamber 140 and the lower chamber 150.

[0033] During wastewater filtration, wastewater enters the lower chamber 150 through the inlet 110. After the lower chamber 150 is filled with wastewater, it enters the ceramic membrane filter tube 210. The clean water filtered by the ceramic membrane filter tube 210 enters the clean water chamber 160 and can be discharged from the clean water outlet 120. The remaining wastewater continues to flow upward to the upper chamber 140 and can be discharged from the wastewater outlet 130.

[0034] The mounting bracket 220 also includes a third mounting plate 223, which is parallel to the first mounting plate 221 and positioned between the first mounting plate 221 and the second mounting plate 222. The third mounting plate 223 supports the middle part of the ceramic membrane filter tube 210, further enhancing the strength of the filter element assembly 200. The third mounting plate 223 is permeable; specifically, it can have permeable holes or be made of a non-watertight material, ensuring that the third mounting plate 223 does not obstruct the clear water chamber 160, allowing water in the clear water chamber 160 to flow out from the clear water outlet 120.

[0035] Reference Figure 1 and Figure 2The lower part of the outer casing 100 is connected to a slag discharge port 310. Specifically, further, a water inlet pipe 300 is provided at the bottom of the lower chamber 150, and the water inlet pipe 300 is connected to a sewage source. The water inlet pipe 300 is connected to a water inlet 110, and the end of the water inlet pipe 300 away from the water inlet 110 forms a slag discharge port 310, at which a slag discharge valve 320 is provided. When the sewage source is connected to the outer casing 100, the slag discharge valve 320 is closed, and sewage can enter the outer casing 100 from the water inlet pipe 300. When the sewage source is shut off, impurities at the bottom of the outer casing 100 can enter the water inlet pipe 300 from the water inlet 110. At this time, the slag discharge valve 320 is opened, and the impurities can be discharged from the slag discharge port 310. Thus, only one water inlet pipe 300 needs to be provided at the bottom of the outer casing 100 to achieve slag discharge and water intake, reducing the number of interfaces, lowering the sealing requirements of the outer casing 100, and reducing production costs. In addition, in other embodiments, the slag discharge port 310 may also be independently disposed at the bottom of the housing 100 relative to the water inlet 110.

[0036] Reference Figure 2 and Figure 3 A scraping assembly 400 is provided inside the bottom of the outer casing 100. The scraping assembly 400 includes a scraper 410, a rotating shaft 420, and a rotation input component 430. The rotating shaft 420 is rotatably arranged along the central axis of the outer casing 100. The scraper 410 is connected to the rotating shaft 420 and fits against the inner wall of the bottom of the outer casing 100. The rotation input component 430 is engaged with the rotating shaft 420 and is used to drive the rotating shaft 420 to rotate around the axis. The rotating shaft 420 is driven to rotate by the rotation output component, thereby causing the rotating shaft 420 to drive the scraper 410 to rotate along the inner wall of the bottom of the outer casing 100, scraping off the impurities deposited inside the bottom wall of the outer casing 100. This allows the impurities to be smoothly discharged from the slag discharge port 310, preventing the accumulation of impurities at the bottom of the outer casing 100 from clogging the ceramic membrane filter tube 210 or the slag discharge port 310, which is beneficial to the normal use of the ceramic membrane filter device 1000.

[0037] In this embodiment, the rotating input component 430 includes an input shaft 431. A rotating shaft 420 is connected to a first bevel gear 421, and the input shaft 431 is connected to a second bevel gear 432 meshing with the first bevel gear 421. The input shaft 431 passes through the housing 100 and protrudes outside the housing 100. The input shaft 431 and the rotating shaft 420 are driven by the meshing of the first bevel gear 421 and the second bevel gear 432, so that when the rotating shaft 420 is rotating around the central axis of the housing 100, the input shaft 431 can be set perpendicular to the rotating shaft 420 and protrude outside the housing 100. This allows the input shaft 431 to avoid the filter element assembly 200 in the middle of the housing 100, thus preventing interference between the input shaft 431 and the filter element assembly 200.

[0038] In other embodiments, the rotary input 430 may also be a motor driveably connected to the rotating shaft 420. In other embodiments, the input shaft 431 may also be axially connected to the rotating shaft 420, in which case the input shaft 431 passes through the bottom of the housing 100.

[0039] Reference Figures 2 to 4 In this embodiment, a mounting hole is provided on the bottom periphery of the outer casing 100, and a mounting sleeve 170 is disposed in the mounting hole. The input shaft 431 passes through the mounting sleeve 170, and the input shaft 431 can rotate axially relative to the mounting sleeve 170, and there is a seal between the input shaft 431 and the mounting sleeve 170. Specifically, an annular groove 433 is provided on the periphery of the input shaft 431, and a sealing ring 434 is nested in the annular groove 433, and the sealing ring 434 abuts against the inner wall of the mounting sleeve 170.

[0040] The input shaft 431 is provided with an inner limiting block 435 and an outer limiting block 436 on opposite sides of the mounting sleeve 170. The inner limiting block 435 is located inside the outer casing 100, and the outer limiting block 436 is located outside the outer casing 100. The inner limiting block 435 and the outer limiting block 436 abut against the two sides of the mounting sleeve 170, thereby axially limiting the input shaft 431 and making it difficult for the input shaft 431 to move axially relative to the mounting sleeve 170.

[0041] A handwheel 437 is fixedly connected to one end of the input shaft 431 that protrudes from the housing 100. Rotating the handwheel 437 drives the input shaft 431 to rotate, which is convenient for user operation.

[0042] Reference Figures 2 to 3 In this embodiment, a rotating bracket 500 is connected to the bottom of the mounting bracket 220. The rotating bracket 500 includes a support rod 510 and a support ring 520. A rotating shaft 420 is rotatably inserted through the support ring 520. The support rod 510 is connected between the support ring 520 and the second mounting plate 222 at the bottom of the mounting bracket 220. The rotating shaft 420 is supported by the support ring 520, which facilitates the installation of the rotating shaft 420. At the same time, when the mounting bracket 220 is removed, the rotating shaft 420 and the scraper 410 can be taken out simultaneously, which facilitates the disassembly and assembly of the scraper assembly 400.

[0043] A ring-shaped limiting groove 422 is provided around the circumference of the rotating shaft 420, and the support ring 520 is fitted into the limiting groove 422, thereby achieving axial limiting of the rotating shaft 420. The support ring 520 can be made of two half-rings spliced ​​together to facilitate the cooperation between the rotating shaft 420 and the support ring 520.

[0044] In this embodiment, the bottom of the outer shell 100 is arc-shaped, and the corresponding scraper 410 is an arc-shaped plate that fits with the bottom of the outer shell 100. In other embodiments, the bottom of the outer shell 100 may also be inverted conical, frustum-shaped, or other shapes, and the corresponding scraper 410 is shaped to fit with the inner wall of the bottom of the outer shell 100, so that the scraper 410 can fit against the bottom wall of the outer shell 100 to scrape the material.

[0045] Reference Figure 1 and Figure 2 In this embodiment, the inlet pipe 300 includes a vertical pipe section 330, a horizontal pipe section 340, and a sewage connection pipe section 350. The vertical pipe section 330 is connected to the inlet 110 at the bottom of the outer casing 100, and the end of the vertical pipe section 330 away from the inlet 110 forms a sludge discharge port 310. The horizontal pipe section 340 is connected to the vertical pipe section 330, and the sewage connection pipe section 350 is connected to the horizontal pipe section 340 and is used to connect to a sewage source.

[0046] Wastewater outlet 130 is connected to a drain pipe 600, which is connected to a horizontal pipe section 340. A first shut-off valve 341 is installed on the horizontal pipe section 340, located between the drain pipe 600 and the inlet pipe 300. A second shut-off valve 351 is installed on the wastewater connection pipe section 350, and a third shut-off valve 610 is installed on the drain pipe 600.

[0047] Therefore, when the first shut-off valve 341, the second shut-off valve 351, and the third shut-off valve 610 are opened, the sewage source water can enter the outer casing 100 through the sewage connection pipe section 350, the horizontal pipe section 340, and the vertical pipe section 330. The sewage filtered by the outer casing 100 flows back to the horizontal pipe section 340 from the sewage outlet 130 and the drain pipe 600, and mixes with the sewage from the sewage connection pipe section 350 before continuing to enter the outer casing 100 for filtration, realizing the circulation filtration of sewage and improving the filtration effect. When the first shut-off valve 341 is closed and the second shut-off valve 351 and the third shut-off valve 610 are opened, the water in the sewage connection pipe section 350 enters the upper chamber 140 from the horizontal pipe section 340 and the drain pipe 600, and flows downward from the upper chamber 140 through the ceramic membrane filter pipe 210 to flush the ceramic membrane filter pipe 210 and the lower chamber 150. Opening the slag discharge valve 320 can discharge the flushed water and impurities, realizing the flushing of the ceramic membrane filter device 1000. Preferably, the sewage connection pipe section 350 can be connected to a clean water source during flushing to improve the flushing effect.

[0048] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
