Description

Technical Field

[0001] This application relates to the field of waste treatment technology, and in particular to a waste bin drainage auxiliary device. Background Technology

[0002] In the waste incineration process, waste is first collected and piled up in a waste storage area for fermentation. The purpose of this fermentation is to remove moisture from the waste and increase its calorific value. A drain outlet is located on one side of the waste storage area, covered by a grating. The grating's function is to filter the waste and allow leachate to drain smoothly. However, during waste storage, the grating at the drain outlet is easily clogged by waste, preventing leachate from draining and causing it to accumulate inside the waste storage area. This can lead to excessively high water levels in the waste storage area, which can affect the fermentation process, reduce the waste's calorific value, and ultimately negatively impact the incineration efficiency.

[0003] In the existing technology, when dealing with the problem of leachate discharge from landfills, the main method used is to directly place a submersible pump to pump out the water. The transportation of the submersible pump mainly relies on manpower. Specifically, the existing technology directly places the submersible pump in the leachate of the landfill to pump out the water.

[0004] However, due to the large amount of garbage in the garbage bin, this garbage may entangle and clog the impeller, inlet and other parts of the submersible sewage pump. Once the submersible sewage pump is clogged or entangled, its pumping efficiency will drop significantly, or it may even fail to work properly. Frequent shutdowns for cleaning and maintenance will be required, increasing labor costs and working time.

[0005] Meanwhile, since the handling of submersible sewage pumps in existing technologies mainly relies on manual labor, and the space inside the garbage bin is large, the position of the submersible sewage pump is difficult to adjust flexibly after it is fixed. When the liquid level of leachate changes or a large amount of leachate accumulates in a local area, the submersible sewage pump cannot be moved to a suitable position in time to pump water, which may still result in some leachate not being effectively discharged. The problem of excessively high water level in the garbage bin and affecting the calorific value of the garbage still exists. Furthermore, the submersible sewage pump placed directly may shift in position during operation due to collisions with garbage, further affecting the pumping effect. Moreover, moving the submersible sewage pump requires manual handling, which is not only laborious but also poses certain safety hazards. Utility Model Content

[0006] The purpose of this application is to provide a waste bin drainage auxiliary device to solve the problems existing in the prior art, such as the submersible pump being easily clogged, affecting its pumping efficiency or even causing it to be damaged and unusable, and the submersible pump being unable to be flexibly adjusted to the appropriate position for pumping water, resulting in some leachate not being effectively discharged, leading to excessively high water levels in the waste bin and affecting the calorific value of the waste.

[0008] A protective cage, and a submersible pump placed inside the protective cage, wherein the protective cage is configured as a perforated mesh frame structure, and the mesh openings are sized to prevent debris from entering; and

[0009] A mobile control mechanism located outside the waste storage area, and a transmission connector that is connected to the mobile control mechanism, wherein the transmission connector is also connected to the protective cage.

[0010] Furthermore, the transmission connector is configured as a cable, which is a steel cable or steel wire rope. One end of the cable is fixedly connected to the top of the protective cage, and the other end is connected to the movement control mechanism.

[0011] Furthermore, the top of the protective cage is provided with a lifting ring, and one end of the cable is provided with a hook for use in conjunction with the lifting ring.

[0012] Furthermore, the mobile control mechanism includes a mobile frame and a lifting device and a control device mounted on the mobile frame. The control device is controlled to the mobile frame and the lifting device, and the mobile frame is provided with pulleys.

[0013] One end of the cable is fixedly connected to the top of the protective cage, and the other end passes around the pulley on the mobile frame and is connected to the lifting device. The control device controls the mobile frame to move so as to drive the protective cage to move horizontally, and the control device controls the lifting device to drive the protective cage to move vertically up and down.

[0014] Furthermore, the mobile control mechanism is configured as a crane, which includes the mobile frame, the lifting device, and the control device;

[0015] The mobile frame includes a frame body and a front end protrusion extending forward from the top of the frame body. A first pulley is provided at the front end of the front end protrusion away from the frame body, and a second pulley is provided at the top of the frame body. The lifting device is located near the side of the frame body away from the front end protrusion, and the cable passes around the first pulley and the second pulley in sequence and is connected to the lifting device.

[0016] Furthermore, the lifting device includes a drum and a motor driven by the drum; one end of the cable is wound and fixedly connected to the drum; and the control device is controlled by the motor; and / or

[0017] The mobile frame also includes a reinforcing support rod, one end of which is fixedly connected to the front end of the front protrusion, and the other end of which is connected to the bottom front side of the frame body.

[0018] Furthermore, the bottom of the main body of the mobile frame is provided with wheels, including a pair of front wheels and a pair of rear wheels respectively disposed on the front and rear sides of the bottom of the main body of the frame. The front wheels are fixed wheels, and the rear wheels are swivel wheels; and / or

[0019] A counterweight structure is installed at the rear of the main body of the vehicle frame; and / or

[0020] The control device is configured as a control box, and is also equipped with a remote control that can be remotely controlled from the control box.

[0021] Furthermore, the mesh openings of the protective cage are set to a size of 3-10cm; and / or

[0023] Furthermore, the waste bin drainage auxiliary device also includes a water pipe made of corrosion-resistant and flexible material, one end of which is sealed to the outlet of the submersible pump, and the other end extends to the leachate collection area.

[0024] Furthermore, the water pipe is provided with a pipe clamp structure for fixing the water pipe; and / or

[0026] Compared with existing technologies, the waste bin drainage auxiliary device provided in this application is equipped with a protective cage, and a submersible sewage pump (i.e., a submersible discharge pump) is placed inside the protective cage. When pumping is required, the pump enters the waste bin together. The protective cage is a mesh-like frame structure with mesh openings sized to block waste from entering, while allowing leachate to enter and be pumped away by the submersible sewage pump. The mesh of the protective cage effectively prevents waste from entering the waste bin, entangled in, and clogging the submersible sewage pump, ensuring its normal and effective operation. Furthermore, the frame structure of the protective cage effectively protects the submersible sewage pump from damage caused by grabs or other devices inside the waste bin, as well as large pieces or hard waste, or from collisions that could cause it to shift and affect its pumping efficiency, further ensuring the normal and effective operation of the submersible sewage pump and extending its service life.

[0027] Furthermore, it includes a mobile control mechanism located outside the waste storage area, and a transmission connector that is connected to the mobile control mechanism, and the transmission connector is also connected to the protective cage. This allows the protective cage and the submersible pump installed inside it to move flexibly under the drive of the mobile control mechanism via the transmission connector. When the leachate level changes or a large amount of leachate accumulates in a localized area, the submersible pump can promptly move to a suitable position to pump water, effectively discharging the leachate and preventing the problem of excessively high water levels inside the waste storage area from affecting the calorific value of the waste.

[0054] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0055] like Figure 1 As shown, this application embodiment provides a waste bin drainage auxiliary device for draining leachate from a waste bin. The waste bin drainage auxiliary device includes a protective cage 20 and a submersible pump 10 placed inside the protective cage 20, as well as a movement control mechanism located outside the waste bin and a transmission connector driven by the movement control mechanism. The transmission connector is also connected to the protective cage 20. The protective cage 20 is configured as a perforated mesh frame structure, and the size of the perforated mesh holes (i.e., the perforated mesh holes 21) is set to a size that can block waste from entering.

[0056] Compared with the prior art, the waste bin drainage auxiliary device provided in this application embodiment is equipped with a protective cage 20, and a submersible sewage pump 10 (i.e., a submersible sewage pump) is placed inside the protective cage 20. When the leachate in the waste bin accumulates due to blockage of the drain outlet and drainage is required, the protective cage 20 and the submersible sewage pump 10 enter the waste bin together. The protective cage 20 is set as a mesh-hole frame structure. The size of the mesh holes is set to be large enough to block the garbage from entering, and the holes allow the leachate to enter and be pumped away by the submersible sewage pump 10.

[0057] The mesh of the protective cage 20 can effectively prevent garbage in the garbage bin from entering, entangled, and clogging the submersible pump 10, ensuring the normal and effective operation of the submersible pump 10. Furthermore, the frame structure of the protective cage 20 can effectively protect the submersible pump 10 placed inside from being damaged by the grab bucket and other devices in the garbage bin, as well as large pieces of garbage and hard garbage, or from being collided with and shifted, thus affecting its pumping effect. This further ensures the normal and effective operation of the submersible pump 10 and extends its service life.

[0058] Furthermore, the waste bin drainage auxiliary device also includes a movement control mechanism located outside the waste bin, and a transmission connector connected to the movement control mechanism, which is also connected to the protective cage 20. This allows the protective cage 20 and the submersible pump 10 installed within it to move flexibly via the transmission connector, driven by the movement control mechanism. When the leachate level changes or a large amount of leachate accumulates in a localized area, the submersible pump 10 can promptly move to a suitable position to pump water, effectively discharging the leachate and preventing excessively high water levels in the waste bin from affecting the calorific value of the waste.

[0059] One specific embodiment is, as follows: Figure 1 As shown, the aforementioned transmission connector can be specifically configured as a cable 40, which can be a steel cable or steel wire rope. One end of the cable 40 is fixedly connected to the top of the protective cage 20, and the other end is connected to the movement control mechanism. This provides high flexibility and convenient wiring.

[0060] In a further embodiment, the top of the aforementioned protective cage 20 may be provided with a lifting ring, and the end of the aforementioned cable 40 used for fixed connection with the protective cage 20 may be provided with a hook for use in conjunction with the lifting ring. Through the use of the hook and the lifting ring, the protective cage 20 and the submersible pump 10 can be lifted and lowered. It also facilitates the quick assembly and quick separation of the protective cage 20 and the cable 40, and facilitates the independent maintenance of the protective cage 20.

[0061] A preferred embodiment is, as follows: Figure 1 As shown, the aforementioned mobile control mechanism can specifically be a crane, which may include a mobile frame 50 and a lifting device 60 and a control device mounted on the mobile frame 50. The control device can specifically be a control box 70, and the mobile frame 50 is provided with pulleys.

[0062] Specifically, one end of the aforementioned cable 40 is fixedly connected to the top of the protective cage 20, and the other end passes around the pulley on the mobile frame 50 and is connected to the lifting device 60. The control device is connected to the mobile frame 50 to control the movement of the mobile frame 50 to drive the protective cage 20 and the submersible pump 10 inside it to move horizontally. The control device is also connected to the lifting device 60 to control the lifting device 60 to drive the protective cage 20 and the submersible pump 10 inside it to rise and fall vertically together, lift, lower or adjust the vertical position.

[0063] Through the coordination of horizontal movement and vertical lifting, the protective cage 20 and the submersible pump 10 inside it can be moved and adjusted flexibly within the garbage bin to a suitable pumping position so as to effectively discharge the leachate.

[0064] A further embodiment is, as follows: Figure 1As shown, the aforementioned mobile frame 50 may specifically include a frame body 51 and a front end extension 52 extending forward from the top of the frame body 51. The front end extension 52 is provided with a first pulley 531 at its front end away from the frame body 51, and a second pulley 532 is provided at the top inside the frame body 51. In the transverse direction, the second pulley 532 is located between the first pulley 531 and the lifting device 60, so that the cable 40 can complete the routing and pass through the first pulley 531 and the second pulley 532 in sequence to connect with the lifting device 60, thereby realizing the lifting and movement control of the protective cage 20 and the submersible pump 10. This method is simple to operate and highly reliable.

[0065] A further embodiment is, as Figure 1 As shown, the lifting device 60 is preferably located near the side of the main frame 51 away from the front extension 52, that is, near the rear of the main frame 51, to maximize the cable routing distance and increase the lifting height range. Furthermore, the control box 70 is preferably located at the rear of the main frame 51 to reduce the control distance to the motor of the lifting device 60.

[0066] In another further embodiment, the extension length of the front end protrusion 52 of the aforementioned mobile frame 50 can be determined according to the actual needs of the garbage bin. Specifically, depending on the height of the garbage bin, the front end protrusion 52 can extend into the upper part of the garbage bin or be located above the outside of the garbage bin. Preferably, the mobile frame 50 can be welded from steel to improve its rigidity and weight, preventing tipping.

[0067] Furthermore, such as Figure 1 As shown, a counterweight structure 56 can be installed at the rear of the main body 51 of the mobile frame 50 to balance the overall mobile frame 50 and prevent the crane from tipping over due to excessive weight of the submersible pump 10 and protective cage 20 connected to its front end.

[0068] Regarding the aforementioned lifting device 60, a specific embodiment is as follows: Figure 1 As shown, the lifting device 60 may specifically include a drum and a motor connected to the drum. One end of the aforementioned cable 40 is wound around and fixedly connected to the drum. The aforementioned control box 70 is connected to the motor and controls the motor to drive the drum to rotate, thereby driving the protective cage 20 and the submersible pump 10 to rise and fall longitudinally.

[0069] An alternative embodiment may also be configured with a remote controller that can be remotely controlled by the control box 70, enabling remote control of take-off and landing, and facilitating staff to remotely observe the internal condition of the waste bin at any time.

[0070] Another alternative embodiment is, as follows: Figure 1As shown, the bottom of the main body 51 of the aforementioned mobile frame 50 may be provided with wheels. Specifically, the wheels may include a pair of front wheels and a pair of rear wheels respectively disposed on the front and rear sides of the bottom of the main body 51. The front wheels may be fixed wheels 551 and the rear wheels may be casters 552, so as to facilitate the flexible movement and easy lifting of the entire device.

[0071] Another alternative embodiment is, as follows: Figure 1 As shown, the mobile frame 50 may also include at least one reinforcing support member for reinforcing the support frame, such as a first reinforcing support member 541 and a second reinforcing support member 542. One end of the first reinforcing support member 541 is fixedly connected to the front end of the front extension 52 of the mobile frame 50, and the other end is connected to the front bottom of the frame body 51 to provide stable support for the extended front extension 52 and prevent it from forming a cantilever beam stress structure that is easy to bend. The second reinforcing support member 542 may be disposed inside the frame body 51 with a larger frame to provide stable support for the frame of the frame body 51.

[0072] In one specific embodiment, the size of the mesh openings in the protective cage 20 can be set according to the size of the garbage in the garbage bin, to prevent garbage from entering the protective cage 20 and clogging or damaging the submersible pump 10, while ensuring that leachate can smoothly enter the cage and be extracted. Specifically, the size of the mesh openings in the protective cage 20 can be set to 3~10cm, preferably 5cm, to effectively prevent garbage in the garbage bin from entering the protective cage 20 and entangled in and clogging the submersible pump 10, thus ensuring its pumping performance.

[0073] Furthermore, the protective cage 20 can be made of high-strength stainless steel to improve its frame strength, thereby effectively blocking the submersible pump 10 inside and preventing it from being damaged by the grab bucket and other devices in the garbage bin, as well as large pieces of garbage and hard garbage, or from being deflected due to collision, thus affecting its pumping effect.

[0074] In a more specific embodiment, the aforementioned protective cage 20 can be a cuboid frame structure, a cube frame structure, or other regular or irregular shaped frame structures. Specifically, the size of the protective cage 20 needs to be slightly larger than the size of the submersible pump 10 to ensure that the submersible pump 10 can be stably placed inside the protective cage 20, and that there is sufficient space within the cage for easy installation and removal. Further preferably, the protective cage 20 may also be equipped with fixing clips for securing the submersible pump 10, effectively preventing displacement of the submersible pump 10 during movement.

[0075] Furthermore, a preferred embodiment is, as follows: Figure 1As shown, the waste bin drainage auxiliary device of this application embodiment may further include a water pipe 30, which is made of a corrosion-resistant and flexible material (such as plastic). One end of the water pipe 30 is sealed to the outlet of the submersible pump 10, and the other end extends to the leachate collection area, which may specifically be a leachate channel or the like. When the submersible pump 10 is working, the pumped leachate flows into the leachate collection area through the water pipe 30. The length of the water pipe 30 can be determined based on the distance between the waste bin and the leachate collection area.

[0076] In a further embodiment, the water pipe 30 may be provided with a pipe clamp structure for fixing the water pipe 30 in a suitable position to prevent it from shaking during the pumping process.

[0077] The specific drainage process can be as follows: When leachate in the waste bin accumulates due to blockage of the drain outlet and needs to be drained, firstly, the moving frame 50 of the crane is moved, and the protective cage 20 and the submersible pump 10 are moved to a suitable position in the waste bin according to the liquid level and distribution of the leachate; then, the lifting device 60 is started and controlled, and the protective cage 20 equipped with the submersible pump 10 is slowly lowered into the leachate in the waste bin. Through the movement of the crane (such as the moving frame 50) and the longitudinal adjustment of the lifting device 60, the submersible pump 10 is placed in a position with more leachate in the waste bin; then, the submersible pump 10 is started, and the submersible pump 10 begins to pump leachate, which is then transported to the leachate collection area through the water pipe 30.

[0078] During the pumping process, the position of the submersible pump 10 within the garbage bin can be adjusted at any time using a crane (such as a mobile frame 50) and a lifting device 60, to ensure maximum effective extraction of leachate. Once the leachate level has dropped to a suitable height, the submersible pump 10 is shut off, and the crane is used to lift the protective cage 20 and the submersible pump 10 from the garbage bin and move them to their storage location.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
