[0002] Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering. In wastewater treatment, filtration technology is one of the most commonly used and crucial methods. It removes suspended solids, particulate impurities, and other pollutants from wastewater through physical interception.
[0003] The existing method of wastewater filtration involves mixing wastewater with chemicals and then introducing the wastewater into a filter assembly, where the filter screen removes impurities from the wastewater. This method requires larger machinery and a larger workspace, which is inconvenient for daily wastewater treatment. Utility Model Content
[0004] The purpose of this invention is to provide a filtration device for wastewater treatment, so as to solve the problem that the treatment method mentioned in the background art, which involves treating wastewater by treatment equipment and then introducing it into the filtration equipment for total filtration, requires larger mechanical equipment and a larger working space.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for sewage treatment, comprising a treatment tank and a filter frame;
[0006] The treatment tank has two drainage chambers inside, and each of the two adjacent drainage chambers is connected to a drain pipe. A sewage pipe is connected to the bottom of the treatment tank. A filter frame is inserted inside the treatment tank. The filter frame has an inlet, filter holes and guide grooves. The filter holes are symmetrically opened on both sides of the filter frame. Transmission gear blocks are equidistantly connected to the bottom of the filter frame. The outer side of the transmission gear blocks meshes with a drive gear. The middle part of the drive gear is connected to the output end of the drive motor through a coupling.
[0007] Preferably, the bottom of the treatment tank is inclined, the bottom of the drive motor is connected to the mounting plate by connecting bolts, one side of the mounting plate is welded to the outer wall of the treatment tank, and a control box is installed on the upper side of the mounting plate.
[0008] Preferably, the guide grooves are symmetrically opened at the top of the filter frame, and threaded guide rods are inserted into both guide grooves, with the bottoms of both threaded guide rods welded to the treatment tank.
[0009] Preferably, the upper sides of both threaded guide rods are threadedly connected to the limiting nut, and steel balls are equidistantly embedded at the bottom of the filter frame.
[0010] Preferably, the bottom of the treatment tank is provided with an insertion groove, the insertion size of the insertion groove matches the bottom size of the filter frame, and the bottom of the steel ball abuts against the inner wall of the insertion groove.
[0011] Preferably, multiple support rods are welded inside the filter frame, and the middle of each of the multiple support rods is welded to the central stirring rod.
[0012] Preferably, each of the multiple support rods is provided with a spiral stirring rod at its bottom. The spiral stirring rod is welded to the support rod via a connecting rod on its outer side, and the spiral stirring rods are evenly distributed inside the filter frame.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the wastewater treatment filtration device is equipped with a rotatable discharge filter frame, which can effectively intercept impurities in the wastewater while facilitating the wastewater treatment process. The filter frame is equipped with a central stirring rod and a spiral stirring rod to stir the wastewater, which can make the wastewater fully mixed with the reagent. This solves the problem that the treatment method of treating wastewater by the treatment equipment and then introducing it into the filtration equipment for total filtration requires larger mechanical equipment and a larger working space.
[0014] 1. This wastewater treatment filtration device, to facilitate wastewater filtration, uses a control box to control a drive motor during filtration. The output of the drive motor, via a coupling, drives a drive gear to rotate, which meshes with a transmission gear block connected to the upper side of the filter frame. This causes the filter frame to rotate smoothly under the action of the guide groove and threaded guide rod. By driving the drive gear and transmission gear block, the number of filter holes entering the drainage chamber can be adjusted, thereby regulating the wastewater discharge volume. When the wastewater needs to be left to settle, the drive gear and transmission gear block are engaged by the drive motor, which moves the filter holes away from the drainage chamber. This wastewater treatment filtration device is equipped with a rotatable discharge filter frame, which can effectively intercept impurities in the wastewater while facilitating wastewater treatment.
[0015] 2. In this wastewater treatment filtration device, to facilitate thorough mixing of wastewater with added chemicals, before the wastewater enters the treatment tank through the inlet, the drive motor is started to rotate in one direction. Through a coupling, the drive gear meshes with the transmission gear block. After adjusting the filter holes to the side away from the drainage chamber, the drive motor is started again, driving the drive gear to rotate reciprocally through the coupling and mesh with the transmission gear block. This causes the filter frame and support rod to rotate, thereby causing the wastewater to be stirred and mixed by the reciprocating movement of the central stirring rod at the bottom of the support rod and the spiral stirring rod connected by the connecting rod. The wastewater treatment filtration device has a central stirring rod and a spiral stirring rod inside the filter frame to ensure thorough mixing of the wastewater with the chemicals.

[0023] 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.
[0024] Please see Figures 1-5 This utility model provides a technical solution: a filtration device for sewage treatment, including a treatment tank 1 and a filter frame 2;
[0025] The treatment tank 1 has two drainage chambers 101 inside, and the adjacent sides of the two drainage chambers 101 are connected to the drainage pipes 102. The bottom of the treatment tank 1 is connected to the sewage pipe 103. A filter frame 2 is inserted inside the treatment tank 1. The filter frame 2 has an inlet 201, a filter hole 202 and a guide groove 203 inside. The filter hole 202 is symmetrically opened on both sides of the filter frame 2. The bottom of the filter frame 2 is equidistantly connected to the transmission gear 3. The outer side of the transmission gear 3 meshes with the drive gear 301. The middle part of the drive gear 301 is connected to the output end of the drive motor 302 through a coupling.
[0026] The bottom of the treatment tank 1 is inclined. The bottom of the drive motor 302 is connected to the mounting plate 303 by connecting bolts. One side of the mounting plate 303 is welded to the outer wall of the treatment tank 1. A control box 304 is installed on the upper side of the mounting plate 303. The guide grooves 203 are symmetrically opened on the top of the filter frame 2. Threaded guide rods 204 are inserted into both guide grooves 203. The bottoms of both threaded guide rods 204 are welded to the treatment tank 1. The upper sides of both threaded guide rods 204 are threadedly connected to the limit nut 205. Steel balls 401 are equidistantly embedded in the bottom of the filter frame 2. The bottom of the treatment tank 1 is provided with an insertion groove 4. The insertion size of the insertion groove 4 matches the bottom size of the filter frame 2. The bottom of the steel balls 401 abuts against the inner wall of the insertion groove 4.
[0027] In practice, to facilitate wastewater filtration, the drive motor 302 is controlled by the control box 304 during wastewater filtration. The output of the drive motor 302 drives the drive gear 301 to rotate via a coupling, which meshes with the transmission gear block 3 connected to the upper side of the filter frame 2. This causes the filter frame 2 to rotate smoothly under the action of the guide groove 203 and the threaded guide rod 204. By driving the drive gear 301 to mesh with the transmission gear block 3, the number of filter holes 202 entering the drainage chamber 101 at the filter frame 2 can be adjusted, thereby adjusting the wastewater discharge volume. Furthermore, when the filter frame 2 rotates back and forth, it can cause the wastewater to shake, thus preventing impurities from adhering to the inner wall of the filter frame 2 during the discharge process. When the wastewater needs to be allowed to settle, the drive motor 302 drives the drive gear 301 to mesh with the transmission gear block 3, which can move the filter holes 202 away from the drainage chamber 101. The position of the filter holes 202 can be adjusted after the wastewater and the agent are fully mixed.
[0028] The threaded connection between the limiting nut 205 and the threaded guide rod 204 is used to limit the filter frame 2 and the treatment tank 1, preventing the filter frame 2 from bouncing during use. The mounting plate 303 is used to install the drive motor 302 and the control box 304. The insertion groove 4 inside the treatment tank 1 is used to insert into the bottom of the filter frame 2, improving the sealing effect of the bottom of the filter frame 2. The inclined setting of the bottom of the treatment tank 1 facilitates the discharge of impurities inside the treatment tank 1 from the sewage pipe 103. This sewage treatment filtration device is equipped with a rotatable sewage discharge filter frame 2, which can effectively intercept impurities in sewage while facilitating sewage treatment.
[0029] See Figures 4-6 It is known that multiple support rods 5 are welded inside the filter frame 2. The middle of each of the multiple support rods 5 is welded to the central stirring rod 501. Each of the multiple support rods 5 is provided with a spiral stirring rod 502 at its bottom. The outer side of the spiral stirring rod 502 is welded to the support rod 5 through a connecting support rod 503. The spiral stirring rods 502 are evenly distributed inside the filter frame 2.
[0030] In specific implementation, to facilitate thorough mixing of wastewater with added chemicals, before the wastewater enters the treatment tank 1 through the inlet 201, the drive motor 302 is started to rotate in one direction. Through the coupling, the drive gear 301 meshes with the transmission gear block 3. After adjusting the filter hole 202 to the side away from the drain chamber 101, the drive motor 302 is started again, driving the drive gear 301 to rotate reciprocally through the coupling, meshing with the transmission gear block 3. This causes the filter frame 2 to rotate repeatedly inside the treatment tank 1. At this time, the support rod 5 inside the filter frame 2 rotates with the filter frame 2, thereby causing the central stirring rod 501 at the bottom of the support rod 5 and the spiral stirring rod 502 connected by the connecting rod 503 to move reciprocally, mixing the wastewater. The spiral arrangement of the spiral stirring rod 502 increases the contact area with the wastewater, allowing the wastewater to come into more thorough contact with the chemicals. This wastewater treatment filtration device, with a central stirring rod 501 and a spiral stirring rod 502 inside the filter frame 2, ensures thorough mixing of the wastewater with the chemicals.
[0031] In summary, when using this wastewater treatment filtration device, before the wastewater enters the treatment tank 1 through the inlet 201, the drive motor 302 is started to rotate in one direction. Through the coupling, the drive gear 301 is driven to mesh with the transmission gear block 3. After adjusting the filter hole 202 to the side away from the drain chamber 101, the wastewater and the agent are introduced into the treatment tank 1 through the inlet 201. After the wastewater and the agent are fully mixed and reacted, the output end of the drive motor 302 is started again to drive the drive gear 301 to rotate through the coupling and mesh with the transmission gear block 3 connected to the upper side of the filter frame 2. This drives the filter hole 202 at the filter frame 2 into the drain chamber 101. At this time, the wastewater will be filtered and discharged from the filter hole 202 at the filter frame 2 into the drain chamber 101, and finally discharged through the drain pipe 102. The steel ball 401 is used to reduce the friction when the filter frame 2 rotates. The contents not described in detail in this description are prior art known to those skilled in the art.
[0032] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
