Description

Technical Field

[0001] The utility model relates to the technical field of scraper filters, in particular to an anti-clogging scraper filter. Background Art

[0002] In industrial production, scraper filters, as highly efficient self-cleaning filtration equipment, are widely used in the purification of various liquids in industries such as chemicals, petroleum, electricity, and waste disposal. Their primary function is to remove suspended solid particles from continuously flowing liquids to protect subsequent process equipment from damage and ensure smooth production processes.

[0003] While traditional scraper filters offer excellent filtering performance and self-cleaning capabilities, in practice, users are often plagued by drain valve clogging, a major obstacle to stability and efficiency. As a key component of scraper filters, the drain valve's primary task is to promptly discharge impurities removed by the scraper during the filter's self-cleaning process, maintaining the filter's interior clean. However, when processing fluids with high solids content and high impurity viscosity, traditional drain valves are prone to clogging, which not only increases filter maintenance costs and downtime, but also severely impacts filtration efficiency and system stability, reducing the economic benefits of the entire production process.

[0004] To this end, the present application proposes an anti-clogging scraper filter to solve the above technical problems. Utility Model Content

[0005] The main purpose of the present invention is to solve the above-mentioned deficiencies and provide an anti-clogging scraper filter, which significantly reduces the risk of clogging, improves the reliability and service life of the filter, and meets the needs of modern industrial production for efficient and stable filtration.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A blockage-resistant scraper filter comprises a filter body, and also includes: a filter cartridge, which is obliquely inserted on one side of the dirt collecting hopper at the bottom of the filter body; a separation sleeve, which is sleeved on the outside of the filter cartridge, and a baffle is provided in the separation sleeve, and the baffle is fixedly connected to the end of the filter cartridge, and the baffle separates the inner cavity of the separation sleeve into a sewage discharge part and a drain part, and a sewage discharge port is provided at the bottom of the sewage discharge part; a liquid collecting bin, which is connected and arranged at the bottom of the drain part; a spiral conveying shaft, which is passed through the filter cartridge, and one end is rotatably arranged on the dirt collecting hopper, and the other end is rotatably arranged at the end of the separation sleeve; a drive assembly, which is fixedly arranged at the end of the separation sleeve and is transmission-connected to the spiral conveying shaft.

[0008] Furthermore, it also includes a water pump, the water inlet of the water pump is connected to the liquid collecting bin, and the water outlet of the water pump is connected to the top of the liquid discharge port of the filter body.

[0009] Furthermore, the height of the sewage outlet is higher than the height of the liquid outlet.

[0010] Furthermore, the dirt collecting hopper is cylindrical as a whole, with two sides of the bottom narrowed and tangent to the outer wall of the filter cartridge.

[0011] Furthermore, an inspection port is provided on the dirt collecting hopper.

[0012] Furthermore, the edge of the spiral conveying shaft is in close contact with the inner wall of the filter cartridge.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The utility model sets a driving component to drive the spiral conveying shaft to rotate, and the spiral conveying shaft drives the impurities and liquid deposited at the bottom of the sewage collecting hopper to rise together and enter the filter cartridge. In the process of passing through the drain part, the liquid passes through the filter gap of the filter cartridge and flows into the liquid collecting bin, while the impurities are transported to the sewage discharge part by the spiral conveying shaft. The impurities are discharged from the sewage outlet under the action of their own gravity, thereby completing the sewage discharge work of the filter. Compared with the traditional solution of setting a sewage discharge valve at the bottom of the sewage collecting hopper, this solution avoids the setting of the valve, thereby reducing the possibility of blockage, and sets a driving component to drive the spiral conveying shaft to rotate, and uses the rotation of the spiral conveying shaft to move and discharge impurities. The structure is simple and reliable and the sewage discharge effect is good.

[0015] 2. The utility model sets a water pump between the liquid collecting bin and the liquid discharge port, pumps the liquid in the liquid collecting bin filtered by the filter cartridge into the liquid discharge port for discharge together, thereby improving the filtering efficiency of the filter body, so that the filter cartridge, separation sleeve, liquid collecting bin and spiral conveying shaft and other structures can not only discharge sewage efficiently but also take into account the role of auxiliary filtration.

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] like Figure 1-5 As shown, the utility model provides an anti-clogging scraper filter, including a filter body 1, and also includes:

[0025] The filter cartridge 3 is obliquely inserted into one side of the dirt collecting hopper 2 at the bottom of the filter body 1;

[0026] The separation sleeve 4 is sleeved on the outside of the filter cartridge 3. A baffle 5 is provided in the separation sleeve 4. The baffle 5 is fixedly connected to the end of the filter cartridge 3. The baffle 5 divides the inner cavity of the separation sleeve 4 into a sewage discharge portion 6 and a drain portion 7. A sewage outlet 8 is provided at the bottom of the sewage discharge portion 6.

[0027] The liquid collecting tank 9 is connected to the bottom of the draining part 7;

[0028] The spiral conveying shaft 10 is inserted into the filter cartridge 3, and one end is rotatably mounted on the dirt collecting hopper 2, while the other end is rotatably mounted on the end of the separation sleeve 4;

[0029] The driving assembly 11 is fixedly arranged at the end of the separation sleeve 4 and is in driving connection with the screw conveying shaft 10 .

[0030] During use, the impurities scraped off from the filter body 1 are deposited in the sewage collecting hopper 2, and the driving component 11 drives the spiral conveying shaft 10 to rotate. The spiral conveying shaft 10 drives the impurities and liquid deposited at the bottom of the sewage collecting hopper 2 to rise together and enter the filter cartridge 3. In the process of passing through the drain part 7, the liquid passes through the filter gap of the filter cartridge 3 and flows into the liquid collecting bin 9, while the impurities cannot pass through the filter gap of the filter cartridge 3 and are transported to the sewage discharge part 6 by the spiral conveying shaft 10. The impurities are discharged from the sewage outlet 8 under the action of their own gravity, thereby completing the sewage discharge work of the filter. Compared with the traditional scheme of setting a sewage valve at the bottom of the sewage collecting hopper 2, this embodiment avoids the setting of the valve, thereby reducing the possibility of blockage, and sets a driving component 11 to drive the spiral conveying shaft 10 to rotate, and uses the rotation of the spiral conveying shaft 10 to move and discharge impurities. The structure is simple and reliable and the sewage discharge effect is good.

[0031] In one embodiment, a water pump 12 is further included. The water inlet of the water pump 12 is connected to the liquid collecting chamber 9, and the water outlet of the water pump 12 is connected to the top of the liquid discharge port 13 of the filter body 1. The liquid entering the liquid collecting chamber 9 has been filtered by the filter cartridge 3 and has been separated from impurities. Therefore, it can be directly discharged as filtered liquid and enter the next process. Therefore, the water pump 12 is provided to pump the liquid in the liquid collecting chamber 9 into the liquid discharge port 13, and then discharged together with the filtered liquid of the filter body 1.

[0032] In one embodiment, the height of the sewage outlet 8 is higher than the height of the liquid outlet 13. Due to the effect of the liquid's own pressure, the liquid in the sewage hopper 2 will be pressed into the drain portion 7 even without the drive of the spiral conveying shaft 10. If too much liquid flows into the liquid collecting bin 9 until the entire drain portion 7 is soaked, the liquid may directly skip the drainage and filtration steps and enter the sewage outlet 6 directly. This design can ensure that the liquid flows out from the liquid outlet 13 first, and it is difficult to be discharged directly from the sewage outlet 8. In addition, this design is actually a safety redundant design. In actual use, due to the presence of the water pump 12, the liquid in the liquid collecting bin 9 will be continuously pumped out, so it is difficult for the liquid collecting bin 9 to be full.

[0033] In one embodiment, the hopper 2 is cylindrical in shape, with its bottom tapering to a point tangential to the outer wall of the filter cartridge 3. This design allows impurities that settle at the bottom of the hopper 2 to naturally converge within the conveying range of the screw conveyor shaft 10, reducing blind spots on the screw conveyor shaft 10 and ensuring efficient discharge of impurities.

[0034] In one embodiment, the dirt collecting hopper 2 is provided with an inspection port 14. This design allows for inspection and clearing of the blockage when the portion of the screw conveying shaft 10 inserted into the dirt collecting hopper 2 is accidentally clogged. When the filter body 1 is operating normally, the inspection port 14 is sealed.

[0035] In one embodiment, the edge of the screw conveying shaft 10 is in close contact with the inner wall of the filter cartridge 3. This design makes it difficult for impurities conveyed by the screw conveying shaft 10 to get stuck in the gap between the screw conveying shaft 10 and the filter cartridge 3, ensuring the normal operation of the screw conveying shaft 10 during long-term use.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.

[0037] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0038] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
