[0002] With the rapid development of the waste incineration power generation industry, environmental protection control has gradually been strengthened. Maintaining 850℃ and 2S is the most basic operating indicator of the waste incineration power generation industry. This high temperature not only ensures the full oxidation of most of the chemically active components in the garbage, but also effectively reduces the generation of toxic gases.

[0003] However, in order to ensure that the environmental protection requirements of 850℃ and 2S are maintained in the furnace during waste incineration, a large amount of auxiliary fuel needs to be put into the site to stabilize the combustion when the combustion conditions are not good.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The embodiment of the present invention provides an underground garbage bin leachate back-spray heating snow melting device, such as Figure 1-11 As shown, the underground garbage bin leachate back-spray heating and snow-melting device includes: a leachate collecting tank 1, used to collect the leachate from the garbage bin; a leachate lifting pump 2, arranged in the leachate collecting tank 1; a heating water tank 8, connected to the garbage bin, the leachate collecting tank 1 and the leachate lifting pump 2 by a leachate recycling pipeline system 3, and the leachate recycling pipeline system 3 is used to control the flow of leachate; a heat exchange coil 9, arranged in the heating water tank 8, with the water inlet end connected to the heating network water supply and the drainage end connected to the heating network return water, for heating the leachate entering the heating water tank 8.

[0035] In this embodiment, the operation of the device first starts from the leachate collection pool 1, which is responsible for collecting leachate from the garbage bin. Subsequently, the leachate lifting pump 2 extracts the leachate and transports it to the heating water tank 8 through the leachate recirculation pipeline system 3. The heat exchange coil 9 in the heating water tank 8 is connected to the heat network, and the heat energy of the heat network is used to heat the leachate. The heated leachate is then sprayed back into the garbage bin through the leachate recirculation pipeline system 3 to increase the temperature and humidity inside the garbage bin, heat the boiler fixed-discharge and continuous-discharge hot water used, and improve the heat utilization rate.

[0036] The core principle of this device is to use heat energy to heat the leachate and improve the environment in the garbage bin by circulating and spraying the leachate back. As a medium, the leachate can not only carry heat energy, but also moisten the garbage and promote fermentation. At the same time, by controlling the flow and heating temperature of the leachate, the temperature and humidity inside the garbage bin can be accurately adjusted.

[0037] The device is particularly suitable for underground garbage bins in northern regions during winter, especially those waste incineration power plants that are affected by low temperatures and low-quality garbage. In such an environment, the device can effectively increase the temperature and humidity in the garbage bin, solving the problem of difficult garbage fermentation.

[0038] By using this device, the speed and effect of garbage fermentation can be significantly improved, and the deterioration of combustion conditions caused by poor fermentation can be reduced. This can not only reduce the input of auxiliary fuel and reduce operating costs, but also help reduce the emission of harmful gases and improve environmental protection effects.

[0039] In a further preferred embodiment of the present invention, pressure sensors 6 are provided on the water inlet and outlet pipes of the leachate recirculation piping system 3 and the heat exchange coil 9, a heating network water supply valve 16 corresponding to the pressure sensor 6 is provided at the near end of the heating network water supply, and a temperature sensor 7 and a sewage pipe 10 are provided on the heating water tank 8.

[0040] In this embodiment, pressure sensors 6 are provided on the water inlet and outlet pipes of the leachate recirculation pipe system 3 and the heat exchange coil 9. These sensors can monitor the pressure changes in the pipes in real time, ensure that the flow of leachate and hot water is within a safe pressure range, and avoid safety problems such as pipe rupture or leakage caused by excessively high or low pressure.

[0041] A heat network water supply valve 16 is provided near the corresponding pressure sensor 6 at the near end of the heat network water supply. This valve can automatically adjust the supply of hot water according to the feedback signal of the pressure sensor 6, so as to achieve accurate control of the heating temperature. When the pressure sensor 6 detects abnormal pressure, the valve can automatically close or adjust the opening to prevent damage to the device due to pressure fluctuations.

[0042] A temperature sensor 7 is provided on the heating water tank 8. This sensor can monitor the temperature in the water tank in real time to ensure that the leachate is heated to a suitable temperature before being sprayed back into the garbage bin. By cooperating with the control system, the temperature sensor can help realize automatic adjustment and control of the heating temperature.

[0043] The heating water tank 8 is also provided with a sewage pipe 10. This pipe is used to regularly discharge the accumulated water and impurities in the water tank to prevent blockage or pollution problems caused by long-term accumulation. By regularly discharging sewage, the inside of the water tank can be kept clean and unobstructed to ensure the normal operation of the device.

[0044] When using the device, operators can monitor and adjust the status of each sensor and valve in real time through the control system. When the leachate flows in the recirculation pipeline system, the pressure sensor will monitor the pressure changes in the pipeline in real time and transmit the signal to the control system. If the pressure is abnormal, the control system will automatically adjust the opening of the heating network water supply valve to maintain the pressure in the pipeline stable. At the same time, the temperature sensor will monitor the temperature in the heating water tank to ensure that the leachate is heated to the appropriate temperature before being sprayed back into the garbage bin.

[0045] Through the improvement of this preferred embodiment, the underground garbage bin leachate back-spray heating snow melting device has been significantly improved in terms of operation accuracy, safety and environmental protection performance. The setting of the pressure sensor and the heating network water supply valve enables the device to more accurately control the heating temperature and pressure, avoiding safety problems caused by pressure fluctuations. The addition of the temperature sensor 7 enables the operator to more intuitively understand the temperature in the heating water tank 8, so as to make more accurate adjustments. The setting of the sewage pipe 10 helps to keep the inside of the water tank clean and unobstructed, and prolong the service life of the device.

[0046] In a further preferred embodiment of the present invention, the leachate recycling pipeline system 3 is provided with an automatic cleaning rotary filter 5, a recycling injection pipe 11 and a frequency conversion controlled injection pump 15, the automatic cleaning rotary filter 5 is provided with a flushing pipeline 4, the automatic cleaning rotary filter 5 is arranged in combination with the flushing pipeline 4, the recycling injection pipe 11 and the frequency conversion controlled injection pump 15 are located on the injection pipeline of the leachate recycling pipeline system 3, and an overflow pipe 12 is provided on the top of the heating water tank 8, and the drainage end of the overflow pipe 12 is connected to the garbage bin.

[0047] In this embodiment, an automatic cleaning rotary filter 5 is provided on the leachate recirculation pipeline system 3. This filter can effectively intercept impurities and particulate matter in the leachate and prevent them from entering the pipeline system and the heating water tank 8, thereby ensuring the stable operation of the device. At the same time, the filter is equipped with a flushing pipeline 4, which can automatically clean the filter regularly to avoid filter blockage and impurity accumulation, and reduce the frequency and cost of manual maintenance.

[0048] Recirculation injection pipe 11 and frequency conversion control injection pump 15: The recirculation injection pipe 11 and frequency conversion control injection pump 15 are arranged on the injection pipeline of the leachate recirculation pipeline system 3. These components can inject the heated leachate into the garbage bin at an appropriate pressure and flow rate, ensuring that the leachate can evenly cover the garbage surface and improve the effect of garbage fermentation. The frequency conversion control injection pump can adjust the injection flow and pressure as needed to adapt to different garbage fermentation requirements and environmental conditions. The frequency conversion control injection pump 15 can modify the pressure of the injection outlet mother pipe in the PLC as needed. At the same time, the injection pipe outlet mother pipe adds a recirculation pipeline, which can effectively protect the injection pump and avoid pump suffocation; the injection nozzle adopts a shower form, which can effectively adjust the injection area. At the same time, the injection port inlet is connected with a hose, which can reduce wear and tear and modify the injection angle at will.

[0049] An overflow pipe 12 is provided on the top of the heating water tank 8, and its drainage end is connected to the garbage bin. This pipe is used to automatically discharge excess water when the water level in the heating water tank 8 is too high to prevent the water tank from overflowing. At the same time, the overflowed water can re-enter the garbage bin to participate in the fermentation process, realizing the recycling of water resources and reducing waste and environmental pollution.

[0050] When the device is used, the leachate is first filtered through the automatic cleaning rotary filter 5 to remove impurities and particulate matter. Then, the clean leachate is driven by the variable frequency controlled jet pump 15 and sprayed into the garbage bin through the recirculation spray pipe 11 at an appropriate pressure and flow rate. During the spraying process, the pressure sensor 6 and the temperature sensor 7 will monitor the pressure in the pipeline and the temperature in the heating water tank in real time to ensure that the leachate is sprayed back under appropriate conditions. When the water level in the heating water tank 8 is too high, the overflow pipe 12 will automatically discharge the excess water and reintroduce it into the garbage bin.

[0051] The improvement of this preferred embodiment has significantly improved the operating efficiency, maintenance cost and environmental performance of the underground garbage bin leachate back-spray heating and snow melting device. The setting of the automatic cleaning rotary filter 5 reduces the frequency and cost of manual maintenance, while improving the cleanliness of the leachate. The synergistic effect of the recirculating injection pipe 11 and the variable frequency controlled injection pump 15 ensures that the leachate can evenly cover the garbage surface, improving the effect of garbage fermentation. The setting of the overflow pipe 12 realizes the recycling of water resources, reducing waste and environmental pollution.

[0052] In a further preferred embodiment of the present invention, the snow melting device also includes a door opening radar interlocking system 13, a temperature control interlocking system 14 and a PLC control system. The door opening radar interlocking system 13 and the temperature control interlocking system 14 are both arranged on the unloading door of the garbage bin and are used to control the injection according to the opening of the unloading door on site. The PLC control system is used to automatically control according to the injection temperature and pressure.

[0053] In this embodiment, the door opening radar joint control system 13 and the temperature control interlocking system 14 are arranged on the unloading door of the garbage bin, and the opening state of the unloading door is monitored in real time by radar technology. When the unloading door is opened, the system can quickly sense and trigger the corresponding control logic to ensure that the injection of leachate can be suspended or adjusted during the unloading process to avoid injection onto the working area or the operator, thereby ensuring the safety of the operation.

[0054] The temperature control interlocking system 14 works in conjunction with the door opening radar interlocking control system. The temperature control interlocking system 14 monitors the temperature in the garbage bin through a temperature sensor. When the temperature reaches a preset threshold, the system automatically adjusts the injection amount, frequency or temperature of the leachate to maintain a suitable fermentation temperature in the garbage bin. This interlocking control can ensure the stability and efficiency of the garbage fermentation process.

[0055] As the core control system of the entire device, the PLC control system is responsible for receiving and processing signals from various sensors and actuators, and automatically controlling according to the preset control logic. It can compare the actual values ​​of the injection temperature and pressure with the target values, and achieve precise control of the leachate injection by adjusting the states of actuators such as valves and pumps in the leachate recirculation pipeline system. In addition, the PLC control system can also achieve linkage control with other systems (such as the ventilation system and deodorization system of the garbage bin), further improving the intelligence level of the entire garbage treatment process.

[0056] During the operation of the device, the door opening radar joint control system 13 and the temperature control interlocking system 14 monitor the unloading door status and internal temperature of the garbage bin in real time, and transmit the relevant information to the PLC control system. The PLC control system automatically adjusts the injection state of the leachate, including the injection amount, frequency, temperature, etc., based on this information and the preset control logic. At the same time, the PLC control system can also accurately control the actuators in the leachate recirculation pipeline system based on the real-time feedback of the pressure sensor 6 and the temperature sensor 7 to ensure that the leachate is sprayed back under appropriate conditions.

[0057] The improvement of this preferred embodiment has significantly improved the safety, control accuracy and intelligent level of the underground garbage bin leachate back-spray heating snow melting device. The introduction of the door opening radar joint control system 13 and the temperature control interlocking system 14 ensures the safety and stability of the device during the unloading process; and the application of the PLC control system realizes the precise control and intelligent management of the leachate injection.

[0058] In a further preferred embodiment of the present invention, a water inlet 17 is opened at the top of the leachate collection tank 1, and a suspended variable height water conducting mechanism is provided in the leachate collection tank 1. The suspended variable height water conducting mechanism includes an isolation plate 18 fixedly installed in the leachate collection tank 1, which is used to isolate the leachate lifting pump 2 and the water inlet side. The isolation plate 18 is located on the water inlet side of the water inlet 17 and is provided with a diversion variable height float 19. The water inlet end of the diversion variable height float 19 is fixedly installed with a water inlet pipe head 20, and the water inlet pipe head 20 can be semi-suspended on the water surface. The water inlet end of the water inlet pipe head 20 is fixedly installed with a pipe head isolation net 21.

[0059] In this embodiment, a water inlet 17 is provided at the top of the leachate collection tank 1, which is the main way for the leachate to enter the collection tank. Inside the leachate collection tank 1, a suspended variable height water conducting mechanism is installed.

[0060] The core component of the suspended variable height water conducting mechanism includes an isolation plate 18. The isolation plate 18 is fixedly installed in the leachate collection tank 1, and its main function is to isolate the leachate lifting pump 2 from the water inlet side to ensure that the leachate can be effectively pre-treated and separated before lifting.

[0061] On the water inlet side of the isolation plate 18, a diversion variable height floating pipe 19 is provided. The design of this floating pipe is very unique, and its height can be automatically adjusted according to the water level of the leachate. Specifically, when the water level of the leachate rises, the floating pipe will also rise accordingly, thereby maintaining a certain distance from the water surface, drawing the relatively clean water above and preventing the impurities precipitated below from entering. This design ensures that no matter how the water level of the leachate changes, the floating pipe can effectively guide the leachate into the designated treatment area.

[0062] The water inlet end of the floating pipe is fixedly installed with a water inlet pipe head 20. The design of the water inlet pipe head 20 is also very clever, and it can be semi-suspended on the water surface. This design allows the water inlet pipe head 20 to automatically adjust its position as the water level changes, and always maintain the best water inlet position. At the same time, the water inlet end of the water inlet pipe head 20 is also fixedly installed with a pipe head isolation net 21. The main function of the isolation net is to prevent garbage or other impurities from entering the water inlet pipe head, thereby ensuring the quality of the leachate entering the treatment system.

[0063] In a further preferred embodiment of the present invention, a support baffle 22 is fixedly installed in the leachate collection tank 1 and between the isolation plate 18, and a lower support plate 23 is also fixedly installed in the leachate collection tank 1, and the lower support plate 23 is located below the support baffle 22, and transmission ear blocks 24 are fixedly installed on both sides of the water inlet pipe head 20, and the same driving screw 25 is rotatably installed on the support baffle 22 and the lower support plate 23, and the driving screw 25 is threadedly connected to the corresponding transmission ear block 24, and a guide rod 26 is slidably installed on the other transmission ear block 24, and the two ends of the guide rod 26 are respectively fixedly connected to the support baffle 22 and the lower support plate 23.

[0064] In this embodiment, a support partition 22 is newly added between the leachate collection tank 1 and the isolation plate 18. This improvement not only enhances the stability of the entire structure, but also provides a solid foundation for the subsequent installation of components. At the same time, the addition of the lower support plate 23 further enhances the support force of the overall structure, ensuring that the structure will not be deformed or damaged during the leachate treatment process.

[0065] It is worth mentioning that transmission lugs 24 are installed on both sides of the water inlet pipe head 20. The two transmission lugs 24 not only provide additional fixing points for the water inlet pipe head 20, but also allow the water inlet pipe head 20 to be threadedly connected with the driving screw 25 through the transmission lugs 24. The driving screw 25 is installed on the supporting baffle 22 and the lower support plate 23, and drives the water inlet pipe head 20 to move up and down by rotating. This design makes the height adjustment of the water inlet pipe head 20 more convenient and accurate, and the position of the water inlet pipe head 20 can be adjusted at any time according to actual needs.

[0066] In addition, a guide rod 26 is installed on the other transmission ear block 24. The two ends of the guide rod 26 are fixedly connected to the supporting partition 22 and the lower support plate 23 respectively, forming a stable guide structure. This design not only ensures the stability of the water inlet pipe head 20 during the lifting process, but also prevents the deviation or shaking caused by the rotation of the driving screw 25.

[0067] In summary, the improvement of this preferred embodiment makes the internal structure of the leachate collection tank 1 more stable and reliable. The addition of the support baffle 22 and the lower support plate 23 enhances the support force of the overall structure, and the combination of the transmission ear block 24, the drive screw 25 and the guide rod 26 makes the height adjustment of the water inlet pipe head 20 more convenient, accurate and stable.

[0068] In a further preferred embodiment of the present invention, a cleaning plate 27 is fixedly mounted on the supporting partition 22 , and the cleaning plate 27 is located on one side of the water inlet pipe head 20 and is provided with brush thorns 28 , and the brush thorns 28 can clean the pipe head isolation net 21 .

[0069] In this embodiment, a cleaning plate 27 is newly added to the supporting baffle 22. The design of the cleaning plate 27 is ingenious and practical. It is located on one side of the water inlet pipe head 20 and is equipped with brush thorns 28. The role of these brush thorns 28 is very critical. They can automatically clean the pipe head isolation net 21 as the water inlet pipe head 20 moves.

[0070] In actual use, when the water inlet pipe head 20 is lifted and lowered, the brush barbs 28 will come into contact with the pipe head isolation net 21 and brush, thereby effectively removing garbage, impurities or dirt attached to the isolation net. This automatic cleaning mechanism not only ensures the cleanliness of the pipe head isolation net 21, prevents blockage and damage, but also improves the efficiency and stability of the entire leachate collection and treatment system.

[0071] In a further preferred embodiment of the present invention, the flow-guiding variable-height floating tube 19 has a telescopic section 29, and the flow-guiding variable-height floating tube 19 is a hose.

[0072] In this embodiment, a telescopic joint 29 is added to the diversion variable height floating tube 19. The design of the telescopic joint 29 enables the floating tube to freely expand and contract within a certain range, thereby adapting to the changes in different water levels. This elasticity not only ensures that the floating tube can always maintain a certain distance from the water surface, but also enables the floating tube to have a certain buffering capacity when subjected to external forces, thereby preventing damage due to excessive stretching or compression.

[0073] In addition, the diversion variable height floating tube 19 itself is made of a hose material. This hose material has the characteristics of being soft and durable, so that the floating tube can be easily bent and deformed to adapt to various complex water flow environments and space restrictions.

[0074] In actual use, when the water level of the leachate changes, the expansion joint 29 can automatically adjust the length of the floating tube so that the floating tube always remains in the best working position. At the same time, the floating tube made of hose material can easily cope with the impact and fluctuation of water flow and maintain stable water conduction performance.

[0075] In summary, by adding the telescopic joint 29 and adopting the hose material, the present invention further improves the adaptability and flexibility of the diversion variable height floating tube 19, so that it can better adapt to various complex working environments and improve the efficiency and quality of leachate collection and treatment.

[0076] In a further preferred embodiment of the present invention, a plate seat 30 is fixedly installed in the support baffle 22, a universal joint coupling 31 is rotatably installed on the plate seat 30, the output end of the universal joint coupling 31 is fixedly connected to the input end of the driving screw 25, a conical gear disk 32 is fixedly installed on the input end of the universal joint coupling 31, a linkage shaft 33 is rotatably installed on the support baffle 22, a bevel gear 34 is fixedly installed on the output end of the linkage shaft 33, and the bevel gear 34 is meshed with the bevel gear disk 32.

[0077] In this embodiment, a fixed installation component, a plate seat 30, is newly added to the support partition 22. A rotatable universal joint coupling 31 is installed on the plate seat 30. This design enables the transmission mechanism to rotate flexibly in multiple directions, thereby adapting to different installation and working environments. The output end of the universal joint coupling 31 is fixedly connected to the input end of the driving screw 25, ensuring effective transmission of power.

[0078] In addition, the input end of the universal joint coupling 31 is fixedly connected to the bevel gear disc 32. A rotatable linkage shaft 33 is also installed on the support partition 22, and a bevel gear 1 34 is fixed to the output end of the linkage shaft 33, which meshes with the bevel gear disc 32. This gear transmission method not only has the advantages of high transmission efficiency and compact structure, but also can realize smooth power transmission and speed adjustment.

[0079] In actual use, the linkage shaft 33 is driven to rotate by an external power source, and the linkage shaft 33 drives the bevel gear 1 34 to rotate, and then drives the universal joint coupling 31 to rotate through the bevel gear plate 32. The rotation of the universal joint coupling 31 is finally transmitted to the driving screw 25, and the driving screw 25 drives the water inlet pipe head 20 to move up and down through the threaded connection. This transmission method not only ensures that the height adjustment of the water inlet pipe head 20 is accurate and reliable, but also improves the efficiency and stability of the entire transmission system.

[0080] In summary, this preferred embodiment of the present invention optimizes the driving mechanism in the leachate collection tank 1 and improves the transmission efficiency and flexibility by introducing components such as the plate seat 30, the universal joint coupling 31, the conical gear plate 32, the linkage shaft 33 and the conical gear 1 34. This improvement not only makes the height adjustment of the water inlet pipe head 20 more convenient and accurate, but also enhances the stability and reliability of the entire leachate treatment system.

[0081] In a further preferred embodiment of the present invention, a circular gear 35 is fixedly installed on the input end of the linkage shaft 33, and a lifting rack 36 is slidably installed on the top inner wall of the leachate collection tank 1. The lifting rack 36 is meshed with the circular gear 35, and a float 37 is fixedly installed on the bottom end of the lifting rack 36. The float 37 can be semi-suspended on the water surface and synchronized with the water inlet pipe head 20.

[0082] In this embodiment, a circular gear 35 is newly added to the input end of the linkage shaft 33. At the same time, a slidable lifting rack 36 is installed on the top inner wall of the leachate collection tank 1, and the rack is tightly meshed with the circular gear 35. When the circular gear 35 rotates, it drives the lifting rack 36 to perform corresponding lifting movements.

[0083] A float 37 is fixedly connected to the bottom end of the lifting rack 36. The design of the float 37 is very clever, and it can be semi-suspended on the water surface and keep synchronous movement with the water inlet pipe head 20. This design enables the float 37 to automatically adjust its position as the water level changes, thereby driving the lifting rack 36 to move up and down accordingly.

[0084] In actual application, when the water level of the leachate rises, the float 37 will also rise, driving the lifting rack 36 to rise. The rising movement of the lifting rack 36 will be transmitted to the linkage shaft 33 through the circular gear 35, thereby driving the water inlet pipe head 20 to rise to adapt to the new water level. Conversely, when the water level drops, the float 37 and the lifting rack 36 will also drop, driving the water inlet pipe head 20 to drop.

[0085] This design not only achieves automatic adaptation of the inlet pipe head 20 to water level changes, but also improves the operating efficiency and stability of the entire system. It reduces the need for manual intervention and reduces maintenance costs, while ensuring the continuity and efficiency of the leachate collection and treatment process.

[0086] In summary, this preferred embodiment of the present invention further optimizes the driving mechanism of the leachate collection tank 1 by introducing components such as the circular gear 35, the lifting rack 36 and the floating ball 37. This improvement not only improves the automation level of the system, but also enhances its adaptability and stability, providing strong support for the efficient collection and treatment of leachate.

[0087] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0088] In another embodiment of the present invention, an upper partition 38 is fixedly installed on the top inner wall of the leachate collection tank 1, and a filter screen 39 is fixedly installed on the bottom of the upper partition 38 and the inner wall of the leachate collection tank 1. The upper partition 38 and the filter screen 39 are located between the water inlet 17 and the float 37, and a water inlet screen 40 is detachably installed in the leachate collection tank 1 corresponding to the water inlet 17.

[0089] In this embodiment, an upper partition 38 is added to the top inner wall of the leachate collection tank 1. The main function of this newly added component is to divide the internal space of the leachate collection tank 1 so that the leachate can be pre-treated and filtered after entering the collection tank.

[0090] A filter screen 39 is fixedly installed between the bottom of the upper partition 38 and the inner wall of the leachate collection tank 1. The design of the filter screen 39 is very critical, as it can effectively intercept and filter out large particles of impurities and suspended matter in the leachate, preventing these impurities from entering the subsequent treatment system, thereby ensuring the quality and treatment effect of the leachate.

[0091] It is worth mentioning that the upper partition 38 and the filter screen 39 are carefully arranged between the water inlet 17 and the float 37. Such a layout allows the leachate to enter the collection tank through the water inlet 17, and then be pre-treated and filtered by the upper partition 38 and the filter screen 39, and then the height of the water inlet pipe head 20 is adjusted by the driving mechanism of the float 37 and the lifting rack 36 to adapt to the water level change.

[0092] In addition, a detachable water inlet screen 40 is added to the leachate collection tank 1 at the position corresponding to the water inlet 17. The design of the water inlet screen 40 further enhances the pretreatment effect of the leachate, and it can further intercept and filter out impurities and particulate matter in the leachate, ensuring that the leachate entering the collection tank has a higher quality.

[0093] The improvement of this embodiment not only improves the effect of leachate collection and treatment, but also enhances the stability and reliability of the entire system. By adding components such as the upper partition 38, the filter screen 39 and the water inlet screen 40, the leachate collection tank 1 can better filter and pre-treat the leachate, providing higher quality raw materials for subsequent treatment processes.

[0094] In another embodiment of the present invention, a wave-raising plate 41 is slidably provided below the water inlet screen 40, the wave-raising plate 41 is slidably in contact with the inner wall of the leachate collection tank 1, and the water-facing surface of the wave-raising plate 41 is arc-shaped.

[0095] In this embodiment, a wave-raising plate 41 is additionally provided below the water inlet screen 40. The wave-raising plate 41 is in slidable contact with the inner wall of the leachate collection tank 1, which means that the wave-raising plate 41 can move freely within a certain range to adapt to the change of water flow when the leachate enters. This design not only enhances the stability of the wave-raising plate 41, but also enables it to function better.

[0096] It is worth mentioning that the water-facing surface of the wave-raising plate 41 is in an arc shape. This arc design enables the wave-raising plate 41 to better cope with the impact of the water flow and produce a greater stirring and mixing effect. When the leachate enters the collection tank through the water inlet 17, the water flow will first impact the arc-shaped water-facing surface of the wave-raising plate 41, thereby generating a strong disturbance and mixing effect, which can make the water surface fluctuate and avoid clogging of the pipe head isolation net 21.

[0097] In addition, the sliding design of the wave-raising plate 41 also allows it to be adaptively adjusted according to the change of water level. When the water level rises, the wave-raising plate 41 can slide upward to adapt to the new water level; when the water level drops, it can slide downward. This adaptive adjustment capability ensures that the wave-raising plate 41 can always achieve the best stirring and mixing effect.

[0098] In another embodiment of the present invention, a plurality of fixed plates 42 are fixedly installed on the side of the leachate collection tank 1, and the same input shaft 43 is rotatably installed on the plurality of fixed plates 42. A plurality of wire shafts 44 are rotatably installed in the leachate collection tank 1. A lifting rope 45 is slidably installed on the inner wall of the leachate collection tank 1, and the lifting rope 45 is wound around the input shaft 43 and the plurality of wire shafts 44. An output shaft 46 is rotatably installed on one side of the leachate collection tank 1, and the input end of the output shaft 46 is located in the supporting partition 22 and fixedly installed with a bevel gear 47, and the bevel gear 47 is meshed with a bevel gear disc 32. A pulley 48 is fixedly installed on the same end of the input shaft 43 and the output shaft 46, and the two pulleys 48 are sleeved with the same synchronous belt 49.

[0099] In this embodiment, a plurality of fixing plates 42 are fixedly mounted on the side of the leachate collection tank 1. These fixing plates 42 not only provide stable support, but also rotatably mount a common input shaft 43 thereon. This design enables the input shaft 43 to rotate stably and flexibly.

[0100] A plurality of wire shafts 44 are rotatably mounted inside the leachate collection tank 1. The wire shafts 44 cooperate with the input shaft 43 to achieve force transmission and conversion through the lifting rope 45. The lifting rope 45 is not only wound around the input shaft 43, but also around the plurality of wire shafts 44. This arrangement enables the lifting rope 45 to move along a specific path under the drive of the input shaft 43.

[0101] In order to achieve stable sliding of the lifting rope 45 in the leachate collection tank 1, the lifting rope 45 is also slidably installed through the inner wall of the leachate collection tank 1. This design ensures that the lifting rope 45 will not be hindered during the movement, thereby ensuring the smooth operation of the entire transmission system, and the lifting rope 45 is passed out at a higher position, so that liquid leakage will not occur.

[0102] On one side of the leachate collection tank 1, an output shaft 46 is also rotatably mounted. The input end of the output shaft 46 is located in the support partition 22, and a bevel gear 2 47 is fixedly mounted. The bevel gear 2 47 meshes with the bevel gear disc 32 mentioned above, thereby forming a gear transmission system. When the bevel gear disc 32 rotates, it drives the bevel gear 2 47 and the output shaft 46 to rotate together, so that the floating ball 37 and the wave lifting plate 41 rise and fall synchronously.

[0103] It is worth noting that a pulley 48 is fixedly mounted on the same end of the input shaft 43 and the output shaft 46. A synchronous belt 49 is sleeved on the two pulleys 48, thereby forming a belt transmission system. This design enables the input shaft 43 and the output shaft 46 to rotate synchronously, ensuring the coordination and stability of the entire transmission system.

[0104] Through the improvement of this embodiment, the leachate collection tank 1 not only has a more complex transmission system, but also realizes the integration of multiple functions. The coordinated work of the lifting rope 45, the input shaft 43, the guide wire shaft 44, the output shaft 46, the bevel gear 2 47 and the synchronous belt 49 makes the leachate collection and treatment process more efficient and stable.

[0105] In another embodiment of the present invention, a cleaning pipe 50 with a valve is provided at the bottom of one side of the leachate collection tank 1, and a stabilizing support plate 51 is fixedly installed on the inner wall of the leachate collection tank 1, and the stabilizing support plate 51 is rotatably connected to the linkage shaft 33.

[0106] In this embodiment, first, a cleaning pipe 50 with a valve is added to the bottom of one side of the leachate collection tank 1. This design allows the staff to regularly clean and maintain the leachate collection tank 1 to ensure the cleanliness and sanitation of the tank. By opening the valve, the residues and dirt in the tank can be easily discharged, thereby maintaining the normal operation and high efficiency of the leachate collection tank 1.

[0107] Secondly, a stabilizing support plate 51 is fixedly installed on the inner wall of the leachate collection tank 1. The stabilizing support plate 51 is rotatably connected to the linkage shaft 33, providing a stable support for the linkage shaft 33. Since the linkage shaft 33 plays a key transmission role in the leachate collection process, its stability is crucial to the normal operation of the entire system.

[0108] In summary, compared with the relevant technologies, this device uses heat energy to heat the leachate, and improves the environment in the garbage bin by circulating and spraying the leachate back; the leachate, as a medium, can not only carry heat energy, but also moisten the garbage and promote fermentation; at the same time, by controlling the flow and heating temperature of the leachate, the temperature and humidity inside the garbage bin can be accurately adjusted;

[0109] The device is particularly suitable for underground garbage bins in northern regions in winter, especially those waste incineration power plants affected by low temperatures and low-quality garbage; in such an environment, the device can effectively increase the temperature and humidity in the garbage bin and solve the problem of difficult garbage fermentation.

[0110] By using this device, the speed and effect of garbage fermentation can be significantly improved, and the problem of deterioration of combustion conditions caused by poor fermentation can be reduced; this can not only reduce the input of auxiliary fuel and reduce operating costs, but also help reduce the emission of harmful gases and improve environmental protection effects.
