Description

Technical Field

[0001] This utility model relates to the field of wastewater pretreatment technology, and in particular to a cleaning component of a wastewater pretreatment device. Background Technology

[0002] Centralized wastewater treatment in industrial production enterprises and decentralized wastewater treatment processes in residential areas both require pretreatment of wastewater. The pretreatment stage is a crucial step before wastewater enters the advanced treatment stages such as flocculation, biological, or chemical treatment, and its importance is self-evident. If pretreatment fails to meet established standards, it will significantly exacerbate the wear and tear on subsequent treatment facilities, equipment, and even structures. Specifically, the core of wastewater pretreatment includes solid-liquid separation, which aims to effectively remove solid impurities from wastewater through preliminary filtration, thereby reducing the burden on subsequent wastewater treatment equipment and significantly improving the overall efficiency of wastewater treatment.

[0003] The applicant disclosed a filtration device for wastewater pretreatment in patent publication number CN221385468U, including a housing, an inlet pipe, a diversion assembly, and a filtration assembly. A filtration chamber is formed inside the housing, and an inlet and an outlet are respectively opened at both ends of the housing. The inlet pipe is installed inside the inlet. The diversion assembly includes a mounting rod, a diversion block, and a diversion plate. The mounting rod is mounted on the housing and connected to the diversion plate. The diversion block is installed on the side of the diversion plate away from the mounting rod, and at least partially extends into the inlet pipe. The radial dimension of the diversion block is smaller than the inner diameter of the inlet pipe, and the diversion block is used to evenly divert wastewater discharged through the inlet pipe to the diversion plate. The filtration assembly includes a first filter screen and a second filter screen. The first filter screen is sleeved on the mounting rod, and its periphery abuts against the inner wall of the housing. The second filter screen is formed in a ring shape, and it is sleeved outside the diversion plate, with the outer periphery of the first filter screen abutting against the inner wall of the housing.

[0004] During the actual operation of the filtration device, the applicant discovered that although this wastewater pretreatment filtration device can evenly distribute wastewater through the diversion component, ensuring that the wastewater can fully contact and flow through the filter component to effectively remove impurities, wastewater often contains various impurities of different properties, including suspended particulate matter, dissolved organic matter, grease, and fat. Among these impurities, viscous impurities, due to their unique adhesion and aggregation properties, easily form an adhesion layer on the surface of the diversion block. Over time, this adhesion layer gradually thickens and easily blocks the inlet channel between the diversion block and the inlet pipe, making it difficult for wastewater to be properly diverted and flow through the filter component. This not only reduces the diversion efficiency but also affects the overall filtration effect of the device. Utility Model Content

[0005] The main purpose of this utility model is to provide a cleaning component for a sewage pretreatment device, which aims to solve the problem that existing sewage pretreatment devices are prone to difficulty in properly diverting sewage due to sticky impurities, which not only reduces the diversion efficiency but also affects the filtration effect of the entire device.

[0006] To achieve the above objectives, this utility model provides a cleaning component for a wastewater pretreatment device, used to remove impurities from the diversion component and filter component in the wastewater pretreatment device. The wastewater pretreatment device has a drive component for driving the diversion component and filter component to rotate, including a connecting seat, a drive member, a scraper, and a pusher. The connecting seat is detachably installed on the inlet pipe of the wastewater pretreatment device. The drive member is disposed on the connecting seat. The power output end of the drive member is movably connected to the scraper. The scraper is used to scrape off impurities attached to the diversion component. One end of the pusher is movably connected to the scraper. The pusher is used to scrape off impurities accumulated on the filter component. The other end of the pusher extends into the sewage pipe.

[0007] Preferably, the scraper includes a connecting part and a pushing scraping part. One end of the connecting part is hinged to the power output end of the driving member through a locking member. The other end of the connecting part extends toward the diversion assembly and is bent to connect with the pushing scraping part. The pushing scraping part has a slope on the side facing the diversion assembly.

[0008] Preferably, a connecting rod is rotatably mounted on the end of the push plate away from the sewage pipe. An adjustment groove is provided on the connecting rod along its extension direction. A locking hole is provided on the push scraping part. The connecting rod is detachably connected to the push scraping part through a fastener that passes through the adjustment groove and the locking hole.

[0009] Preferably, the bottom surface of the connecting rod is flush with the bottom surface of the scraping part.

[0010] Preferably, a baffle is provided near the top of the push plate, the baffle extends in the same direction as the push plate, and the end of the baffle away from the scraper extends into the drain pipe.

[0011] Preferably, a guide slope is formed on the push plate, the guide slope is located below the baffle, and the bottom of the guide slope is located close to the sewage pipe.

[0012] Preferably, the push plate and the baffle are an integral structure.

[0013] Beneficial effects:

[0014] 1. In the cleaning component of the wastewater pretreatment device of this utility model, the adhesive layer formed by sticky impurities on the diversion component is scraped off by a scraper, which effectively prevents impurities from clogging the liquid inlet channel between the diversion block and the inlet pipe, ensuring the normal diversion of wastewater by the diversion component and improving the diversion efficiency.

[0015] 2. In the cleaning component of the wastewater pretreatment device of this utility model, the push plate can scrape the impurities on the filter component and guide the impurities into the sewage pipe, thereby not only ensuring the smooth flow of the filter component and the filtration effect on wastewater, but also improving the reliability and stability of the wastewater pretreatment device.

[0016] 3. Since the power output end of the drive component is movably connected to the scraper, and one end of the push plate is movably connected to the scraper, the operator can adjust the installation position of the scraper and push plate according to the different specifications and shapes of the diversion components. This not only ensures the cleaning effect of impurities, but also improves the applicability of this utility model to different sewage pretreatment devices, making it flexible and convenient to use.

[0030] Example 1:

[0031] This utility model proposes a cleaning component for a sewage pretreatment device.

[0032] In one embodiment of this utility model, a cleaning component of a sewage pretreatment device 100 is used to remove impurities from the diversion component 101 and the filter component 102 in the sewage pretreatment device 100. The sewage pretreatment device 100 has a drive component 103 for driving the diversion component 101 and the filter component 102 to rotate, including a connecting seat 201, a drive member 202, a scraper 203 and a pusher 204. The connecting seat 201 is detachably installed on the inlet pipe 104 of the sewage pretreatment device 100. The drive member 202 is disposed on the connecting seat 201. The power output end of the drive member 202 is movably connected to the scraper 203. The scraper 203 is used to scrape off the impurities attached to the diversion component 101. One end of the pusher 204 is movably connected to the scraper 203. The pusher 204 is used to scrape off the impurities accumulated on the filter component 102. The other end of the pusher 204 extends into the drain pipe 105.

[0033] It should be noted that, as Figure 1 and Figure 2 As shown, during the operation of the wastewater pretreatment device 100, wastewater flows through the inlet pipe 104 to the diversion component 101. The diversion component 101 is a frustum-shaped diversion plate in the prior art (refer to a filter device for wastewater pretreatment disclosed in the applicant's patent publication number CN221385468U). At this time, the diversion component 101 diverts the wastewater, so that the wastewater flows evenly to the filter component 102. The filter component 102 is a filter screen plate in the prior art, so that the wastewater can pass through the filter component 102. The filter removes impurities from the wastewater. Meanwhile, since the filtered impurities remain on the upper surface of the filter assembly 102, and for the sticky impurities remaining on the diversion assembly 101, the filter assembly 102 can be rotated relative to the inlet pipe 104 by the drive assembly 103 (which can be a motor and shaft as in the prior art). In conjunction with the cleaning assembly 200 of the wastewater pretreatment device of this utility model, the impurities can be guided to the drain pipe 105 for discharge and collection, thereby completing the cleaning operation of impurities and ensuring the filtration effect of the entire device.

[0034] Specifically, such as Figures 1 to 5 As shown, in the cleaning component 200 of the sewage pretreatment device of this utility model, since the connecting seat 201 is detachably installed on the inlet pipe 104 of the sewage pretreatment device 100, the detachable installation method of the connecting seat 201 and the inlet pipe 104 can be a clamp or clamp connection, which facilitates the disassembly and assembly of the connecting seat 201; furthermore, since the driving component 202 is set on the connecting seat 201, and the power output end of the driving component 202 is movably connected to the scraper 203, the driving component 202 can be a cylinder, hydraulic cylinder or linear drive mechanism in the prior art, so that the driving component 202 can drive the scraper 203 to move relative to the inlet pipe 104, and the structural design is simple and reasonable. When it is necessary to clean the impurities on the diversion component 101, the drive component 103 of the sewage pretreatment device 100 can drive the diversion component 101 to rotate relative to the inlet pipe 104, while the drive component 202 drives the scraper 203 to move and come into contact with the surface of the diversion component 101. The scraper 203 can then scrape off the layer of adhesive impurities on the diversion component 101, effectively preventing impurities from clogging the liquid inlet channel between the diversion block and the inlet pipe 104, ensuring the normal diversion of sewage by the diversion component 101, and improving the diversion efficiency.

[0035] Understandably, after the scraper 203 scrapes away the impurities on the diversion component 101, the impurities will fall onto the filter component 102. Since one end of the pusher 204 is movably connected to the scraper 203 and the other end of the pusher 204 extends into the drain pipe 105, as the drive component 103 drives the filter component 102 to rotate, the pusher 204 can push and scrape the impurities on the filter component 102 and guide the impurities into the drain pipe 105. This not only ensures the smooth flow of the filter component 102 and the filtration effect on sewage, but also improves the reliability and stability of the sewage pretreatment device 100. It is worth noting that, since the power output end of the drive component 202 is movably connected to the scraper 203, and one end of the push plate 204 is movably connected to the scraper 203, specifically, the movable connection between the scraper 203, the push plate 204 and the drive component 202 can all be made by rotating bolts. This allows the operator to adjust the installation position of the scraper 203 and the push plate 204 according to the different specifications and shapes of the diversion components 101. This not only ensures the cleaning effect of impurities, but also improves the applicability of this utility model to different sewage pretreatment devices 100, making it flexible and convenient to use.

[0036] In one embodiment, the scraper 203 includes a connecting portion 205 and a scraping portion 206. One end of the connecting portion 205 is hinged to the power output end of the drive member 202 via a locking member. The other end of the connecting portion 205 extends toward the diversion assembly 101 and is bent to connect with the scraping portion 206. The scraping portion 206 has a ramp 207 formed on the side facing the diversion assembly 101. Specifically, as shown... Figure 2 and Figure 3 As shown, the locking element can be a screw or stud, as is available in the prior art, allowing the scraper 203 to rotate relative to the drive component 202. This enables flexible adjustment of the installation angle of the scraper 203, allowing it to better adapt to the surface shape of the diversion component 101. This ensures that the scraper 203 can comprehensively and evenly scrape away impurities adhering to the surface of the diversion component 101, ensuring reliable operation. Furthermore, the ramp 207 reduces the contact area between the scraper 203 and the diversion component 101, thereby reducing the frictional resistance between the scraper 203 and the impurities and improving scraping efficiency.

[0037] In one embodiment, such as Figure 1 and Figure 5 As shown, a connecting rod 208 is rotatably mounted on the end of the push plate 204 away from the drain pipe 105. An adjustment groove 209 is provided on the connecting rod 208 along its extension direction, and a locking hole is provided on the scraping part 206. The connecting rod 208 is detachably connected to the scraping part 206 via a fastener passing through the adjustment groove 209 and the locking hole. Understandably, when the angle or height of the diversion assembly 101 changes, the operator can adjust the installation position of the connecting rod 208 on the scraping part 206, thereby ensuring that the push plate 204 always maintains tight contact with the filter assembly 102, thus guaranteeing the cleaning effect of the push plate 204 on the impurities on the filter assembly 102. Furthermore, since the connecting rod 208 is detachably connected to the scraping part 206 via a fastener that passes through the adjusting groove 209 and the locking hole, the fastener can be a set screw or the like in the prior art, which not only facilitates the disassembly and assembly of the connecting rod 208 and the push plate 204, but also facilitates the adjustment of the installation position of the connecting rod 208 on the scraping part 206.

[0038] In one embodiment, such as Figure 2 , Figure 3 and Figure 5 As shown, the bottom surface of the connecting rod 208 is flush with the bottom surface of the scraping part 206. Understandably, when the angle or height of the diversion component 101 changes, the connecting rod 208 can cooperate with the scraper 203 to simultaneously scrape away impurities on the diversion component 101, thereby ensuring the cleaning effect of impurities, reducing impurity residue, and the structural design is simple and reasonable.

[0039] In one embodiment, a baffle 210 is provided near the top of the push plate 204. The extension direction of the baffle 210 is consistent with the extension direction of the push plate 204, and the end of the baffle 210 away from the scraper 203 extends into the drain pipe 105. Specifically, as shown... Figures 1 to 5 As shown, the baffle 210 prevents impurities accumulated on the pusher 204 from overturning during the scraping process, thus improving the scraping efficiency of the pusher 204 and ensuring effective cleaning. Furthermore, since the end of the baffle 210 away from the scraper 203 extends into the drain pipe 105, it stably guides impurities into the drain pipe 105, improving the discharge efficiency.

[0040] In one embodiment, such as Figures 1 to 3 As shown, a guide slope 211 is formed on the push plate 204. The guide slope 211 is located below the baffle 210, and the bottom of the guide slope 211 is set close to the drain pipe 105, so that impurities can flow more smoothly along the guide slope 211 into the drain pipe 105, preventing impurities from accumulating on the push plate 204 or the filter assembly 102, and improving cleaning efficiency.

[0041] In one embodiment, the push plate 204 and the baffle 210 are an integral structure, thereby omitting the assembly steps between the push plate 204 and the baffle 210, avoiding assembly gaps, eliminating assembly errors, and being easy to manufacture.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
