[0001] This utility model belongs to the field of wastewater technology, specifically a filtration device for wastewater treatment. Background Technology

[0002] The production process of purified terephthalic acid (PTA) generates a large amount of wastewater containing complex pollutants (such as high concentrations of organic matter, benzene compounds, suspended solids, catalyst residues, acidic substances, etc.).

[0003] Wastewater treatment filtration equipment is specifically designed to remove solid impurities, suspended solids, and some colloidal pollutants from wastewater. Its core function is to reduce wastewater turbidity and pollutant load, providing qualified influent for subsequent biological treatment or deep purification, and ultimately achieving wastewater discharge or reuse that meets standards.

[0004] During the wastewater filtration process, a large amount of filter debris is generated inside the filter cartridge. When the debris accumulates, it needs to be cleaned. At this time, it is necessary to disassemble and install components such as the filter cartridge. If the operation is not done properly, it can easily lead to problems such as damage to the seals and deformation of the filter screen, which can shorten the service life of the equipment and increase maintenance and replacement costs. Therefore, a wastewater treatment filtration device is proposed to address the above problems. Utility Model Content

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a filtration device for sewage treatment. With the filter barrel and filter rack, when the filter barrel is driven to rotate at high speed around the central axis, the impurities that remain on the outer surface of the filter rack are thrown off the filter rack by the rotational force and fall into the collection mechanism due to the conical structure of the filter barrel, thus completing the cleaning and collection of impurities.

[0015] This utility model provides a filtration device for sewage treatment. During the filtration process, some of the water flows down the inclined surface of the filter rack. At this time, the water can be introduced back into the lower filter rack through the drainage hole, which avoids the situation where some water has poor filtration effect and improves the filtration effect of sewage.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Specific implementation examples are given below.

[0028] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a filtration device for sewage treatment, including a base frame 1; characterized in that: a wrapping frame 11 is fixedly installed on the top of the base frame 1; a feed hopper 12 and a motor 13 are fixedly installed on the top of the wrapping frame 11; a rotating rod 14 is installed at the output end of the motor 13; an upper drive plate 15 and a lower drive plate 16 are fixedly installed on the upper and lower sides of the rotating rod 14; a filter barrel 17 is fixedly installed between the upper drive plate 15 and the lower drive plate 16; a water filter rack 18 is fixedly installed inside the filter barrel 17 corresponding to the conical bottom; a water outlet 19 is opened at the bottom of the filter barrel 17; the upper drive plate 15 and the lower drive plate 16 are rotatably installed inside the wrapping frame 11; during operation, when sewage enters the filter barrel 17 through the feed hopper 12... After a period of time, the filter rack 18 inside the filter bucket 17 performs a three-layer filtration effect on the sewage. After the water passes through the three layers of the filter rack 18, it is discharged through the outlet 19. At the same time, the filtered impurities remain on the outer surface of the filter rack 18. After a period of time, when the water has been basically discharged, the motor 13 is started, which drives the upper drive plate 15 and the lower drive plate 16 to rotate at high speed through the rotating rod 14. At the same time, it can drive the filter bucket 17 to rotate at high speed around the central axis. During the high-speed rotation of the filter bucket 17, the impurities remaining on the outer surface of the filter rack 18 are thrown off the filter rack 18 by the rotational force and fall into the collection mechanism due to the conical structure of the filter bucket 17, thus completing the cleaning and collection of impurities.

[0029] Furthermore, such as Figure 3 , Figure 6As shown, a connecting block 2 is fixedly installed at the conical part of the filter bucket 17 corresponding to the filter rack 18; the connecting block 2 separates the bottom of the conical part of the filter bucket 17 and correspondingly opens a placement groove 21; a collection box 22 is detachably installed at the placement groove 21; slots 3 are opened on the side walls of the connecting block 2; inserts 31 are fixedly installed on the side walls of the connecting block 2 corresponding to the slots 3; inserts 31 are engaged inside the slots 3; a handle 7 is fixedly installed at the bottom of the collection box 22; when impurities are removed from the filter rack 18 and blocked by the conical structure of the filter bucket 17, they will fall downwards due to their own gravity and fall into the collection box. Inside 22, after the impurities are collected, the collection box 22 is pulled outward by operating the handle 7, so that the insert block 31 is disengaged from the slot 3, and the disassembly of the collection box 22 is completed. After the collection box 22 is taken to the outside for cleaning, the handle 7 is operated again to move the collection box 22 to the outside of the placement slot 21, and then the insert block 31 is aligned with the slot 3 and inserted. The installation of the collection box 22 is completed by the locking and limiting of the slot 3 and the insert block 31. At the same time, the installation space of the collection boxes 22 on both sides is formed by the isolation of the connecting block 2, so that the collection box 22 and the filter barrel 17 are tightly fitted together, improving the sealing of the device.

[0030] Furthermore, such as Figure 4 As shown, a rotating track 4 is provided between the top of the base frame 1 and the bottom of the packaging frame 11; during the rotation of the filter barrel 17, the bottom of the filter barrel 17 passes through the rotating track 4, which also provides support for the bottom of the filter barrel 17, thereby ensuring the stability of the filter barrel 17 during rotation.

[0031] Furthermore, such as Figure 5 As shown, multiple sets of drainage holes 5 are opened on the inner side of the filter bucket 17 corresponding to the bottom connection of the filter rack 18. During the filtration process of the filter rack 18, some water flows down the slope of the filter rack 18. At this time, the water can be introduced back into the lower filter rack 18 through the drainage holes 5, so as to avoid the situation that some water has poor filtration effect and improve the filtration effect of sewage.

[0032] Furthermore, such as Figure 1 As shown, a filter screen 6 is detachably installed on the top of the feed hopper 12; wastewater is first poured into the feed hopper 12, and during this process, the filter screen 6 plays a preliminary filtering role, which can isolate some large impurities and prevent them from passing through the feed hopper 12.

[0033] Working principle: During operation, wastewater is first poured into the feed hopper 12. During this process, the filter screen 6 provides initial filtration, separating large impurities and preventing them from passing through the feed hopper 12. After the wastewater enters the filter tank 17 through the feed hopper 12, it waits for a period of time. During this time, the filter rack 18 inside the filter tank 17 performs a three-layer filtration of the wastewater. The water, after passing through the three layers of the filter rack 18, is discharged through the outlet 19. Meanwhile, the filtered impurities remain on the outer surface of the filter rack 18. After a period of time, once the water has been mostly drained, the motor 13 is started, driving the upper drive disc 15 and lower drive disc 16 to rotate at high speed via the rotating rod 14. Simultaneously, this drives the filter barrel 17 to rotate at high speed around its central axis. During this high-speed rotation, impurities remaining on the outer surface of the filter rack 18 are thrown off by the rotational force and blocked by the conical structure of the filter barrel 17, falling into the collection mechanism, thus completing the cleaning and collection of impurities. When the impurities detach from the filter rack 18 and are blocked by the conical structure of the filter barrel 17, they will... The material falls downwards under its own weight, thus entering the collection box 22. After the impurities are collected, the collection box 22 is pulled outwards by operating the handle 7, causing the insert 31 to disengage from the slot 3, completing the disassembly of the collection box 22. After the collection box 22 is taken outside for cleaning, the handle 7 is operated again to move the collection box 22 outside the placement slot 21. Then, the insert 31 is aligned with the slot 3 and inserted. The engagement between the slot 3 and the insert 31 completes the installation of the collection box 22. At the same time, the connection block 2 separates the two collection boxes 22. The installation space allows the collection box 22 to fit tightly against the filter barrel 17, improving the sealing of the device. During the rotation of the filter barrel 17, the rotating track 4 provides support for the bottom of the filter barrel 17, thus ensuring the stability of the filter barrel 17 during rotation. During the filtration process of the water filter rack 18, some water flows down the slope of the water filter rack 18. At this time, the water can be introduced back into the lower water filter rack 18 through the water leakage hole 5, avoiding the situation where some water has poor filtration effect and improving the filtration effect of sewage.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
