Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically to wastewater filtration devices. Background Technology

[0002] With the acceleration of urbanization, the discharge of urban sewage has increased rapidly. Water pollution is severe and is becoming a significant factor restricting development. Sewage treatment is a crucial link in controlling water pollution, and filtration is an essential process in sewage treatment. Urban sewage contains a large amount of solids, and most of these solids must be removed before further treatment.

[0003] In the prior art, belt filter devices are usually used to filter water. These filter devices have perforated holes on the conveyor belt. The mixture to be filtered is poured into the input end of the belt. The fluid passes through the perforated holes and is discharged, while the solids, which cannot pass through the perforated holes, remain on the belt and follow it to the output end for discharge, thereby achieving filtration and separation.

[0004] When using belt filter devices for wastewater filtration, wastewater often contains thin, flaky impurities such as leaves and plastic bags. These impurities tend to adhere to the belt and cannot be removed on their own, thus clogging the perforated holes formed on the belt and affecting the filtration efficiency and effect. When impurities clog the perforated holes, they can only be cleaned manually, which is time-consuming, labor-intensive, and difficult to meet production requirements. Summary of the Invention

[0005] In view of this, the present invention provides a wastewater filtration device to solve the problem in the prior art that impurities easily adhere to the belt of the filtration device and cannot be removed on their own, thus affecting the filtration efficiency and effect.

[0006] The present invention provides a wastewater filtration device, including a separation tank, a conveying mechanism and a roller brush. The separation tank is provided with a fluid zone and a solid zone. The conveying mechanism is disposed in the separation tank, with one end of the conveying mechanism located above the fluid zone and the other end located above the solid zone. The conveying mechanism is provided with a plurality of perforated holes and is adapted to convey the medium from one side of the fluid zone to one side of the solid zone. The roller brush abuts against the end of the conveying mechanism located in the solid zone.

[0007] Beneficial effects: In this invention, the roller brush and the conveying mechanism are connected at one end in the solid zone. Water falls from the perforated hole into the fluid zone through the conveying mechanism. The solids remaining on the conveying mechanism are transported to the solid zone along with the conveying mechanism. Under the action of the roller brush, they are detached from the conveying mechanism and collected in the solid zone, thereby avoiding the blockage of the perforated hole by impurities adhering to the conveying mechanism and ensuring the efficiency and effect of sewage filtration.

[0008] In one alternative embodiment, the conveying mechanism includes a first roller, a second roller, and a conveyor belt. The first roller is disposed in the fluid zone, the second roller is disposed in the solid zone, the conveyor belt is sleeved on the first roller and the second roller, and the conveyor belt is provided with a plurality of perforated holes. The roller brush abuts against the conveyor belt.

[0009] In one alternative embodiment, a plurality of ejector pins are provided on the outer wall of the second roller, and the ejector pins correspond to the hollow holes.

[0010] Beneficial effects: The present invention has several pins on the outer wall of the second roller corresponding to the hollow holes. When the conveyor belt rotates on the second roller, the pins pass through the hollow holes on the conveyor belt, thereby removing impurities adhering to the conveyor belt from the hollow holes, avoiding impurities from clogging the hollow holes, and ensuring the efficiency and effect of sewage filtration.

[0011] In one alternative implementation, the first roller is installed at a height no higher than the second roller.

[0012] Beneficial effects: By setting the installation height of the first roller to be no higher than that of the second roller, the present invention can prevent water from flowing into the solid zone during sewage filtration, thereby achieving the separation of fluid and solid.

[0013] In one alternative implementation, the second roller is a drive roller.

[0014] In one optional embodiment, the outer wall of the conveyor belt is provided with a plurality of protruding ridges, the length direction of which is perpendicular to the moving direction of the conveyor belt.

[0015] Beneficial effects: The present invention provides several protruding ridges on the outer wall of the conveyor belt. The protruding ridges can increase the roughness of the outer surface of the conveyor belt, thereby improving the adhesion of impurities and facilitating the collection and transportation of impurities to the solid area.

[0016] In one alternative implementation, the roller brush is located below the second roller and abuts against the outer side of the conveyor belt.

[0017] Beneficial effects: In this invention, the roller brush abuts against the outer side of the conveyor belt below the second roller. When the debris moves to the solid zone with the conveyor belt, the roller brush sorts the debris from the surface of the conveyor belt, and the impurities can fall into the solid zone, which facilitates the collection of impurities.

[0018] In one alternative embodiment, the separation tank is provided with a baffle that divides the separation tank into a fluid zone and a solid zone.

[0019] Beneficial effects: The present invention uses a partition to divide the pool into a fluid zone and a solid zone by setting a partition in a pool structure, which can reduce the space occupied.

[0020] In one alternative embodiment, the fluid zone is provided with a guide plate, and the conveying mechanism is located below the guide plate.

[0021] Beneficial effects: By setting up a guide plate, the present invention can guide sewage to the transmission mechanism, and the sewage can be filtered as the transmission mechanism operates, thus preventing unfiltered sewage from flowing directly into the fluid zone.

[0022] In one alternative implementation, the solids area is provided with a door.

[0023] Beneficial effects: The present invention features a compartment door so that solid impurities can be easily removed from the solid area, improving the ease of use of the equipment.

[0024] In one alternative embodiment, the fluid zone is provided with a drain outlet located below the conveying mechanism.

[0025] Beneficial effects: The present invention provides a drain outlet in the fluid zone, which allows the filtered fluid to be smoothly discharged from the fluid zone, avoiding fluid stagnation and backflow, and further improving filtration efficiency. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] If the background section does not describe the shortcomings of the prior art, this section analyzes the shortcomings of the prior art in detail to introduce this solution.

[0037] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0038] According to embodiments of the present invention, such as Figures 1 to 4 As shown, a wastewater filtration device is provided, including a separation tank 1, a conveying mechanism 2, and a roller brush 3. The separation tank 1 is provided with a fluid zone 101 and a solid zone 102. The conveying mechanism 2 is disposed in the separation tank 1, with one end of the conveying mechanism 2 located above the fluid zone 101 and the other end located above the solid zone 102. The conveying mechanism 2 is provided with a plurality of perforated holes 201. The conveying mechanism 2 is adapted to transport the medium from one side of the fluid zone 101 to one side of the solid zone 102. The roller brush 3 abuts against the end of the conveying mechanism 2 located in the solid zone 102.

[0039] Specifically, in this embodiment, the separation tank 1 is not specifically limited. For example, such as Figure 1 As shown, in this embodiment, the separation tank 1 can be a rectangular or circular tank with an open top. The tank contains a fluid zone 101 and a solid zone 102. The transmission mechanism is located inside the tank, with one end in the fluid zone 101 and the other end in the solid zone 102. When wastewater containing impurities is transported to the transmission mechanism 2, the water falls through the perforated hole 201 on the transmission mechanism 2 and is collected in the fluid zone 101. The impurities in the wastewater are transported to the solid zone 102 by the transmission mechanism 2.

[0040] In this embodiment, as Figure 1 and Figure 2 As shown, the roller brush 3 is rotatably mounted in the solid zone 102. The roller brush 3 abuts against one end of the conveying mechanism 2 located in the solid zone 102. When the conveying mechanism 2 transports impurities to the solid zone 102, the rotating roller brush 3 separates the impurities adhering to the conveying mechanism 2 from the conveying mechanism 2 and collects them in the solid zone 102.

[0041] In this invention, the roller brush 3 and the conveying mechanism 2 are connected at one end in the solid zone 102. Water falls from the hollow hole 201 into the fluid zone 101 through the conveying mechanism 2. The solids remaining on the conveying mechanism are transported to the solid zone 102 along with the conveying mechanism. Under the action of the roller brush 3, they are removed from the conveying mechanism 2 and collected in the solid zone 102, thereby avoiding the blockage of the hollow hole 201 by impurities adhering to the conveying mechanism 2, and ensuring the efficiency and effect of sewage filtration.

[0042] In one embodiment, such as Figures 1 to 4 As shown, the conveying mechanism 2 includes a first roller 202, a second roller 203, and a conveyor belt 204. The first roller 202 is disposed in the fluid zone 101, the second roller 203 is disposed in the solid zone 102, and the conveyor belt 204 is sleeved on the first roller 202 and the second roller 203. The conveyor belt 204 is provided with a plurality of perforated holes 201, and the roller brush 3 abuts against the conveyor belt 204.

[0043] Specifically, in this embodiment, the first roller 202 is rotatably disposed in the fluid zone 101, the second roller 203 is rotatably disposed in the solid zone 102, and the conveyor belt 204 is sleeved on the first roller 202 and the second roller 203. The conveying direction of the conveyor belt 204 is from the fluid zone 101 to the solid zone 102. Sewage is input into the conveyor belt 204 from the side closer to the fluid zone 101. The water in the sewage enters the fluid zone 101 through the perforated hole 201. Impurities in the sewage are transported to the solid zone 102 with the conveyor belt 204. The roller brush 3 abuts against the outer wall of the conveyor belt 204. Under the action of the roller brush 3, the impurities adhering to the conveyor belt 204 are separated from the conveyor belt 204 and into the solid zone 102.

[0044] In one embodiment, such as Figure 2 and Figure 4 As shown, the outer wall of the second roller 203 is provided with several ejector pins 205, and the ejector pins 205 correspond to the hollow holes 201.

[0045] Specifically, in this embodiment, the ejector pin 205 is not specifically limited. For example, in this embodiment, the ejector pin 205 is a protrusion protruding outward from the outer wall of the second roller 203, and the height of the protrusion is greater than the depth of the hollow hole 201. The arrangement of several ejector pins 205 on the outer wall of the second roller 203 corresponds to the arrangement of the hollow holes 201 on the conveyor belt 204. When the hollow hole 201 on the conveyor belt 204 rotates to the second roller 203, the ejector pin 205 at the corresponding position extends into the hollow hole 201, and the protruding protrusion separates the impurities adhering to the hollow hole 201 from the conveyor belt 204.

[0046] The present invention provides a plurality of ejector pins 205 on the outer wall of the second roller 203 corresponding to the hollow holes 201. When the conveyor belt 204 rotates on the second roller 203, the ejector pins 205 pass through the hollow holes 201 on the conveyor belt 204, thereby removing impurities adhering to the conveyor belt 204 from the hollow holes 201, avoiding impurities from clogging the hollow holes 201, and ensuring the efficiency and effect of sewage filtration.

[0047] In one embodiment, such as Figure 1 As shown, the installation height of the first roller 202 is not higher than that of the second roller 203.

[0048] Specifically, in this embodiment, the first roller 202 is installed at a lower height than the second roller 203, and the conveyor belt 204 is installed on the first roller 202 and the second roller 203 at an incline. Since the second roller 203 is higher than the first roller 202, when sewage is transported to the conveyor belt 204, the flow of water to the solid area 102 where the second roller 203 is located can be reduced, while the impurities separated by the perforated holes 201 move to the solid area 102 with the conveyor belt 204, thereby realizing the separation and collection of water and impurities in sewage.

[0049] The present invention sets the installation height of the first roller 202 to be no higher than that of the second roller 203, which can prevent water from flowing into the solid zone 102 during sewage filtration, thereby achieving the separation of fluid and solid.

[0050] In one embodiment, the second roller 203 is the drive roller.

[0051] Specifically, in this embodiment, the first roller 202 is configured as the driven shaft, and the second roller 203 is configured as the driving shaft. The second roller 203 is connected to a driver fixed outside the separation tank 1. The driver body is fixedly mounted on the outer surface of the side wall of the separation tank 1, and its output shaft is connected to the second roller 203 to transmit torque. Under the drive of the driver, the second roller 203 can rotate. Furthermore, because a conveyor belt 204 is fitted onto the first roller 202 and the second roller 203, and the conveyor belt 204 is in a taut state, the first roller 202 will also rotate under the action of friction.

[0052] In one embodiment, such as Figures 2 to 4 As shown, the outer wall of the conveyor belt 204 is provided with several protruding ribs 206, and the length direction of the protruding ribs 206 is perpendicular to the moving direction of the conveyor belt 204.

[0053] Specifically, in this embodiment, a receiving groove is formed between adjacent protrusions 206 on the conveyor belt 204. Impurities after the water is filtered out can be collected in the receiving groove and fall into the solid area 102 as the conveyor belt 204 moves to the second roller 203.

[0054] The present invention provides several protruding ridges 206 on the outer wall of the conveyor belt 204. The protruding ridges 206 can increase the roughness of the outer surface of the conveyor belt 204, thereby improving the adhesion of impurities and facilitating the collection and transportation of impurities to the solid area 102.

[0055] In one embodiment, such as Figure 1 and Figure 2 As shown, the roller brush 3 is located below the second roller 203, and the roller brush 3 abuts against the outer side of the conveyor belt 204.

[0056] Specifically, in this embodiment, the roller brush 3 is attached to the lower surface of the conveyor belt 204. The roller brush 3 rubs against the conveyor belt 204, thereby peeling off solid impurities adhering to the surface of the conveyor belt 204 and causing them to fall into the solid area 102. By setting the roller brush 3, the conveyor belt 204 can be self-cleaned, thereby effectively reducing the probability of the perforated holes 201 being blocked by solid impurities.

[0057] In this invention, the roller brush 3 abuts against the outer side of the conveyor belt 204 below the second roller 203. When the debris moves to the solid area 102 with the conveyor belt 204, the roller brush 3 sorts the debris from the surface of the conveyor belt 204, and the impurities can fall into the solid area 102, which is convenient for the concentrated collection of impurities.

[0058] In one embodiment, such as Figure 1 As shown, the separation tank 1 is equipped with a baffle 103, which divides the separation tank 1 into a fluid zone 101 and a solid zone 102.

[0059] Specifically, in this embodiment, a partition 103 is provided in the middle of the separation tank 1. The extension direction of the partition 103 is perpendicular to the movement direction of the conveyor belt 204. The partition 103 divides the separation tank 1 into a fluid zone 101 and a solid zone 102.

[0060] The present invention uses a partition 103 to divide the separation tank 1 into a fluid zone 101 and a solid zone 102 within a tank structure, which can reduce the space occupied.

[0061] In one embodiment, such as Figure 1 As shown, the fluid zone 101 is provided with a guide plate 104, and the conveying mechanism 2 is located below the guide plate 104.

[0062] Specifically, in this embodiment, the separation tank 1 is provided with an inlet, which is located on the side of the fluid zone 101 away from the solid zone 102. The height of the inlet is lower than the installation height of the second roller 203. The guide plate 104 is provided at the inlet and extends into the fluid zone 101. The first roller is located below the guide plate 104. Wastewater is input from the inlet along the guide plate 104 to the conveyor belt 204.

[0063] By setting the guide plate 104, the present invention can guide the sewage to the transmission mechanism. With the operation of the transmission mechanism, the sewage can be filtered, thus preventing unfiltered sewage from flowing directly into the fluid area 101.

[0064] In one embodiment, such as Figure 1 As shown, the solid area 102 is equipped with a door 105.

[0065] Specifically, a door 105 is provided on the side of the solid zone 102 away from the fluid zone 101.

[0066] The present invention provides a door 105 so that solid impurities can be easily removed from the solid area 102, thereby improving the ease of use of the equipment.

[0067] In one embodiment, such as Figure 1 As shown, the fluid zone 101 is provided with a drain outlet 106, which is located below the conveying mechanism 2.

[0068] Specifically, in this embodiment, a drain outlet 106 is provided at the bottom of the fluid region 101 on the side away from the solid region 102.

[0069] The present invention provides a drain outlet 106 in the fluid zone 101, so that the filtered fluid can be smoothly discharged from the fluid zone 101, avoiding fluid retention and backflow, and further improving the filtration efficiency.

[0070] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
