Description

Technical Field

[0001] This utility model relates to the field of landfill leachate treatment technology, specifically a biological treatment device for landfill leachate. Background Technology

[0002] Landfill leachate is a high-concentration organic wastewater that originates from the moisture contained in the waste itself, rainwater and snowmelt entering the landfill, and other moisture, after deducting the saturated water holding capacity of the waste and the cover soil layer, and passing through the waste layer and the cover soil layer. Existing landfills need to treat leachate before landfilling to prevent leachate from seeping into the soil and causing pollution to the land and water sources.

[0003] A search revealed that Chinese patent application number 202222357926.9 discloses a landfill leachate treatment device, including a collection tank. The top of the collection tank is bolted to a leachate extrusion tank. The top of the leachate extrusion tank has an inlet, and a feeding plate is hinged to the side of the top of the leachate extrusion tank near the inlet. A fixed platform is bolted to the other side of the top of the leachate extrusion tank near the inlet, and a first cylinder is bolted to the top of the fixed platform.

[0004] While the aforementioned patent facilitates the extraction of wastewater from garbage, it still has the following shortcomings during use:

[0005] 1. During long-term use, when the garbage is placed in the filter rack for wastewater squeezing, the first and second filter holes are prone to blockage due to the accumulation of impurities, making it difficult for the wastewater in the garbage to be fully squeezed out. This not only reduces the wastewater treatment efficiency, but may also cause residual wastewater from landfilling to seep into the soil, causing environmental pollution.

[0006] 2. When wastewater is drawn by a liquid pump, solid impurities may remain in the wastewater due to incomplete filtration. These impurities can easily cause wear or blockage inside the pump body after entering the liquid pump, thereby affecting the normal operation of the equipment and reducing the wastewater extraction efficiency.

This not only reduces wastewater treatment efficiency but may also allow residual wastewater from landfilling to seep into the soil, causing environmental pollution. Furthermore, when wastewater is extracted using a pump, incomplete filtration may leave solid impurities in the wastewater. These impurities, once inside the pump, can easily cause internal wear or blockage, affecting the normal operation of the equipment and reducing wastewater extraction efficiency.

[0011] Preferably, the triangular block is triangular in shape, one side of the guide block is inclined, and the guide block and the triangular block are in contact and engaged.

[0012] Preferably, the vibration component includes a rotating rod rotatably connected inside the separation hopper, a pair of vibration blocks fixedly connected to the rotating rod, a vibration groove formed on the inner wall of the separation hopper, a second spring fixedly connected below the filter plate, the end of the second spring away from the filter plate being fixedly connected to the vibration groove, a pair of reset plates fixedly connected inside the separation hopper, the reset plates being elastically connected to the filter plate through a third spring, and a drive motor fixedly connected to the separation hopper, the output end of the drive motor being fixedly connected to the rotating rod.

[0013] Preferably, a first water outlet pipe is fixedly connected to the separation hopper, and a second water outlet pipe is fixedly connected to the processing hopper. The first water outlet pipe is connected to the separation hopper, and the second water outlet pipe is connected to the filter box. Both the first water outlet pipe and the second water outlet pipe are equipped with solenoid valves.

[0014] Preferably, a first anti-clogging rod is rotatably connected inside the filter box. One end of the first anti-clogging rod, which is located inside the first water outlet pipe, is also fixedly connected to a plurality of evenly distributed first scrapers. One end of the first anti-clogging rod, which passes through the treatment bucket, is connected to the drive motor via a first pulley set.

[0018] This utility model provides a biological treatment device for landfill leachate, which has the following advantages compared with the prior art:

[0019] 1. The inclined filter plate can vibrate to prevent clogging. The cleaning pad rotates along the outer wall of the separation ring to clean impurities inside the separation ring. In addition, the scraper removes impurities from the filter box, thereby improving the removal efficiency of sewage from garbage. It is more convenient to use and solves the problem in the existing technology that, during long-term use, when garbage is placed in the filtrate rack for wastewater squeezing, the first and second filter holes are easily blocked by the accumulation of impurities. This makes it difficult to fully squeeze out the wastewater from the garbage, which not only reduces the wastewater treatment efficiency, but may also cause residual wastewater from landfill to seep into the soil and cause environmental pollution.

[0020] 2. By using the first anti-blocking rod to drive the first scraper to clear the first outlet pipe and the second anti-blocking rod to drive the second scraper to clear the second outlet pipe when discharging sewage through the first and second outlet pipes, the wastewater discharge efficiency can be improved, thereby increasing work efficiency. This solves the problem in the prior art where, when wastewater is drawn by a liquid pump, incomplete filtration may leave solid impurities in the wastewater. These impurities, once they enter the liquid pump, can easily cause internal wear or blockage of the pump body, thus affecting the normal operation of the equipment and reducing the wastewater extraction efficiency.

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.

[0035] Please see Figure 1-5This utility model provides a technical solution: a biological treatment device for landfill leachate, including a treatment hopper 100 and a separation ring 124. A movable frame 101 is fixedly connected above the treatment hopper 100. A pair of sliding grooves 102 are provided above the movable frame 101.

The gear 106 meshes with the rack 107. A connecting frame 108 is fixedly connected below the gear 106. A cleaning pad 109 for cleaning the outer wall of the separation ring 124 is fixedly connected below the connecting frame 108. A first driving screw 112 is rotatably connected to the movable frame 101. The drive screw 112 is threadedly connected to the adjusting plate 103. A filter component is connected inside the processing hopper 100. A separation hopper 110 is fixedly connected to the processing hopper 100. A filter plate 111 is inclinedly arranged inside the separation hopper 110. A vibration component for driving the filter plate 111 to move up and down is connected inside the separation hopper 110. A squeezing component for squeezing the garbage is connected to the moving frame 101. When the adjusting plate 103 slides above the moving frame 101, the gear 106 rotates under the action of the rack 107 and drives the cleaning pad 109 to rotate along the outer wall of the separation ring 124 through the connecting frame 108, thereby cleaning the impurities on the separation ring 124. The cleaning pad 109 is made of flexible material and has brush strips on its surface, which makes it easier to contact the outer wall of the separation ring 124, which is beneficial to improving the continuous treatment of sewage inside the garbage and making it more convenient to use.

[0036] like Figure 1-8 As shown, in a preferred embodiment, based on the above method, the filter component further includes a filter box 120 fixedly connected inside the processing hopper 100. The filter box 120 has multiple evenly distributed filter grooves 121. A pair of push grooves 122 are provided on the inner side wall of the processing hopper 100. A slider 123 is slidably connected in the push groove 122. A separation ring 124 is fixedly connected between the two sliders 123. A plurality of evenly distributed water outlet grooves 132 are provided in the separation ring 124. A cleaning pad 109 contacts and cooperates with the outer wall of the separation ring 124. A second drive screw 133 is rotatably connected in the push groove 122. The second drive screw 133 is threadedly connected to the slider 123. The second drive screw 133 drives the slider 123 to move, thereby adjusting the position of the separation ring 124, thereby cleaning the garbage squeezed inside the separation ring 124 and improving the ease of use.

[0037] like Figure 1-12As shown, in a preferred embodiment, based on the above method, a deflection plate 125 is rotatably connected to the slider 123, and a scraper 126 is rotatably connected between the two deflection plates 125. A pair of guide grooves 127 are provided on the inner side wall of the processing bucket 100. The guide groove 127 includes an inclined part, a vertical part and two horizontal parts. A reset groove 128 is provided in the guide groove 127. A triangular block 129 is slidably connected in the reset groove 128. A first spring 130 is fixedly connected between the reset groove 128 and the triangular block 129. A guide block 131 is slidably connected in the guide groove 127. The guide block 131 is also fixedly connected to the scraper 126. When the guide block 131 contacts the triangular block 129, the triangular block 129 is squeezed into the reset groove 128. When the guide block 131 moves away from the triangular block 129, the first spring 130 drives the triangular block 129 to reset. When the scraper 126 resets, the guide block 131 is pushed into the inclined part, thereby improving the usage effect.

[0038] like Figure 1-12 As shown, in a preferred embodiment, based on the above method, the triangular block 129 is triangular, and one side of the guide block 131 is inclined. The guide block 131 contacts and cooperates with the triangular block 129. Because one side of the guide block 131 is inclined, when it contacts one side of the triangular block 129, it is beneficial to squeeze the triangular block 129, which is beneficial to improve work efficiency.

[0039] like Figure 1-11 As shown, in a preferred embodiment, based on the above method, the vibration component further includes a rotating rod 140 rotatably connected inside the separation hopper 110, a pair of vibration blocks 141 fixedly connected to the rotating rod 140, a vibration groove 142 formed on the inner wall of the separation hopper 110, a second spring 143 fixedly connected below the filter plate 111, and the end of the second spring 143 away from the filter plate 111 is also fixedly connected to the vibration groove 142. A pair of reset plates 144 are fixedly connected inside the separation hopper 110, and the reset plates 144 are elastically connected to the filter plate 111 through a third spring 145. A drive motor 146 is fixedly connected to the separation hopper 110, and the output end of the drive motor 146 is fixedly connected to the rotating rod 140. Through the elastic action of the second spring 143 and the third spring 145, the filter plate 111 can shake up and down, preventing garbage from clogging the holes on the filter plate 111 and promoting the initial separation of wastewater in the garbage.

[0040] like Figure 1-6As shown, in a preferred embodiment, based on the above method, a first water outlet pipe 150 is fixedly connected to the separation hopper 110, and a second water outlet pipe 151 is fixedly connected to the processing hopper 100. The first water outlet pipe 150 is connected to the separation hopper 110, and the second water outlet pipe 151 is connected to the filter box 120. Solenoid valves 152 are provided on both the first water outlet pipe 150 and the second water outlet pipe 151. Through the provision of the first water outlet pipe 150 and the second water outlet pipe 151, the sewage inside the separation hopper 110 and the processing hopper 100 can be discharged, thereby improving the convenience of sewage discharge.

[0041] like Figure 1-7 As shown, in a preferred embodiment, based on the above method, a first anti-clogging rod 153 is rotatably connected inside the filter box 120. One end of the first anti-clogging rod 153, which is located inside the first water outlet pipe 150, is also fixedly connected to a plurality of evenly distributed first scraper strips 154. One end of the first anti-clogging rod 153, which passes through the treatment bucket 100, is connected to the drive motor 146 via the first pulley group 155. When the first anti-clogging rod 153 rotates, it can drive the first scraper strips 154 to rotate inside the first water outlet pipe 150, thereby better preventing the first water outlet pipe 150 from being blocked and improving the drainage effect.

[0042] like Figure 1-6 As shown, in a preferred embodiment, based on the above method, a second anti-blocking rod 156 is rotatably connected inside the separation hopper 110. One end of the second anti-blocking rod 156, located inside the second water outlet pipe 151, is also fixedly connected to a plurality of evenly distributed second scrapers 158. One end of the second anti-blocking rod 156, which passes through the filter box 120, is connected to the drive motor 146 via the second pulley group 157. The drive motor 146 drives the second anti-blocking rod 156 to rotate via the second pulley group 157. The arrangement of the second scrapers 158 can more effectively prevent the second water outlet pipe 151 from becoming blocked, thereby improving work efficiency.

[0043] like Figure 1-5 As shown, in a preferred embodiment, based on the above method, the extrusion component further includes a cylinder 160 fixedly connected to the upper part of the movable frame 101. The output end of the cylinder 160 passes through the bearing groove 105 and is also fixedly connected to an extrusion plate 161. The cylinder 160 pushes the extrusion plate 161 into the interior of the separation ring 124, thereby treating the sewage inside the garbage, which is beneficial to more thorough treatment of the sewage inside the garbage.

[0044] like Figure 1-7As shown, in a preferred embodiment, based on the above method, at least four placement slots 162 are further provided in the adjustment plate 103. A movable wheel 163 is rotatably connected in the placement slot 162. The movable wheel 163 also slides in the slide groove 102. When the adjustment plate 103 slides, the movable wheel 163 rotates in the slide groove 102, thereby reducing the friction of the adjustment plate 103 and helping to extend the service life of the adjustment plate 103.

[0045] During operation (or use): First, the drive motor 146 is started, driving the rotating rod 140 to rotate. When the rotating rod 140 rotates, the vibrating block 141 squeezes the filter plate 111, causing the filter plate 111 to slide upwards. When the vibrating block 141 moves away from the filter plate 111, the second spring 143 and the third spring 145 drive the filter plate 111 to reset, allowing the waste to be poured into the filter plate 111 inside the separation hopper 110. The water inside the waste undergoes preliminary filtration through the holes in the filter plate 111. The filtered water enters the separation hopper 110, where the filter plate 111 is tilted and continuously vibrates, causing the waste to enter the separation ring 124. When the separation ring 124... Once the garbage inside reaches a certain height, the garbage dumping stops. The second drive screw 133 is activated, driving the slider 123 to move, causing the separation ring 124 to move to the top of the squeezing plate 161. The cylinder 160 is activated, pushing the squeezing plate 161 downwards, into the separation ring 124, and squeezing the garbage. This causes the liquid inside the garbage to be squeezed out through the water outlet 132 and then through the filter tank 121 into the filter box 120, achieving centralized wastewater treatment. After the water inside the garbage is completely squeezed out, the first drive screw 112 and the second drive screw 133 are activated simultaneously. The first drive screw 112 drives the adjusting plate 103 to move, and the moving wheel 163 slides in the slide groove 102, raising the adjusting plate. For ease of movement, the second drive screw 133 drives the separating ring 124 to move synchronously. When the adjusting plate 103 moves, the gear 106 rotates under the action of the rack 107, and drives the cleaning pad 109 to rotate along the outer wall of the separating ring 124 through the connecting frame 108, cleaning the blockage impurities in the water tank 132. When the separating ring 124 moves, the slider 123 drives the deflection plate 125 to move. The deflection plate 125 pulls the scraper 126 to slide on the filter box 120, cleaning the blockage impurities in the filter tank 121. When the separating ring 124 moves away from the filter box 120, the processed waste falls to one side of the processing bucket 100 under the action of gravity. 6. Impurities are scraped to the same side of the processing hopper 100. When the guide blocks 131 on both sides of the scraper 126 contact the triangular block 129, the triangular block 129 is squeezed into the reset groove 128. When the guide blocks 131 move away from the triangular block 129, the first spring 130 drives the triangular block 129 to reset. When the separation ring 124 resets, the guide blocks 131 slide along the triangular block 129 into the inclined part. The deflection plate 125 deflects to avoid affecting the movement of the scraper 126. When the guide groove 127 moves to the vertical part, the scraper 126 falls to the bottom horizontal part under the action of gravity, preventing impurities from being scraped to the side of the scraper 126 away from the garbage storage area, thus improving the usage effect.

[0046] Meanwhile, during use, when it is necessary to discharge wastewater from the separation hopper 110 and the treatment hopper 100, the solenoid valve 152 is opened, causing the first outlet pipe 150 and the second outlet pipe 151 to begin draining. Simultaneously, the drive motor 146 rotates, driving the first anti-blocking rod 153 to rotate via the first pulley assembly 155. The first scraper 154 rotates inside the first anti-blocking rod 153, preventing impurities from clogging the first outlet pipe 150. The second pulley assembly 157 drives the second anti-blocking rod 156 to rotate, causing the second scraper 158 to rotate inside the second outlet pipe 151, thus preventing impurities from clogging the second outlet pipe 151. This improves the smoothness of wastewater discharge and makes it more convenient to use.
