Description

Technical Field

[0001] This utility model belongs to the field of waste incineration technology, specifically relating to a leachate filter box for a municipal solid waste incineration power generation incinerator. Background Technology

[0002] With the rapid development of China's economy and the continuous improvement of people's living standards, the amount of urban domestic waste in China has also increased rapidly. Compared with sanitary landfill and composting, waste incineration has great advantages in terms of volume reduction, harmlessness, and resource utilization. Especially in large and medium-sized cities with high population density, scarce land resources, and high calorific value of waste, as well as in economically developed coastal areas, waste incineration has been vigorously developed. Urban domestic waste in China contains a lot of kitchen waste, has a high water content, and a low calorific value, making the treatment of leachate in waste incineration particularly important.

[0003] Existing municipal solid waste incineration power plants typically have a leachate collection hopper below the grate feed hopper, with a leachate collection pipe below the hopper to collect the leachate from the waste. However, the leachate often contains impurities that enter the collection pipe, causing blockages. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a leachate filter box for a municipal solid waste incineration power generation incinerator, so as to solve the problem that leachate usually carries impurities into the collection pipe, thereby causing the collection pipe to become blocked.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model discloses a leachate filter box for a municipal solid waste incineration power generation incinerator, comprising a main body box and an inlet pipe. The inlet pipe is located on the side of the main body box. A filter device is connected inside the main body box. The filter device includes: a discharge pipe, a filter plate, a motor, a cam, a fixing block, a spring, a connecting rod, an impurity discharge port, and a control valve. The discharge pipe is connected to the bottom of the main body box. The filter plate is located inside the discharge pipe and is slidably connected to the discharge pipe. The fixing block is located on the inner wall of the discharge pipe. One end of the connecting rod is fixedly connected to the fixing block, and the other end of the connecting rod passes through the filter plate and is slidably connected to the filter plate. The spring is located between the fixing block and the filter plate. One end of the motor is fixedly connected to the outside of the discharge pipe. The motor output shaft passes through the discharge pipe and is fixedly connected to the cam. The cam is located below the filter plate. The impurity discharge port is located on one side of the discharge pipe, and the control valve is located inside the impurity discharge port.

[0007] Furthermore, two electric cylinders are connected inside the main body box, and a baffle is connected to the output shaft of the electric cylinder. A controller is connected to the outside of the main body box, and there are two discharge pipes, with the two baffles located above the discharge pipes.

[0008] Furthermore, the control valve includes: a fixed rod, a spiral rod, a guard plate, and a fixed plate. The impurity discharge port has a groove.

[0022] like Figures 1-6 As shown, this utility model discloses a leachate filter box for a municipal solid waste incineration power generation incinerator, comprising a main body box 1 and an inlet pipe 2. The inlet pipe 2 is located on the side of the main body box 1, through which leachate enters the main body box 1. A filter device 6 for filtering impurities is connected inside the main body box 1. The filter device 6 includes: a discharge pipe 61, a filter plate 64, a motor 66, a cam 65, a fixing block 62, a spring 63, a connecting rod 69, an impurity discharge port 67, and a control valve 68. The discharge pipe 61 communicates with the bottom of the main body box 1, allowing leachate to be discharged from the main body box 1. The filter plate 64 is located inside the discharge pipe 61 and slidably connected to it, and is angled to allow impurities to slide. The fixing block 62 is located on the inner wall of the discharge pipe 61. One end of the connecting rod 69 is fixedly connected to the fixing block 62, and the other end of the connecting rod 69 passes through the filter plate 64 and slidably connects to it, allowing the filter plate 64 to slide on the connecting rod 69. The spring 63 is located between the fixed block 62 and the filter plate 64, allowing the filter plate 64 to return to its original position. One end of the motor 66 is fixedly connected to the outside of the discharge pipe 61. The output shaft of the motor 66 passes through the discharge pipe 61 and is fixedly connected to the cam 65, which drives the cam 65 to rotate. The cam 65 is located below the filter plate 64, and its rotation causes the filter plate 64 to vibrate. The impurity discharge port 67 is located on one side of the discharge pipe 61 and is used to discharge impurities. The control valve 68 is located inside the impurity discharge port 67 to prevent leachate from flowing out.

[0023] Two electric cylinders 4 are connected inside the main body box 1. The output shaft of each electric cylinder 4 is connected to a baffle 5. The electric cylinder 4 moves the baffle 5 to block the discharge pipe 61. A controller 3 is connected to the outside of the main body box 1. The controller 3 controls the start and stop of the electric cylinders 4 and the motor 66. There are two discharge pipes 61, allowing leachate to be discharged alternately. The two baffles 5 are located above the discharge pipes 61 and are used to block the discharge pipes 61.

[0024] The control valve 68 includes a fixed rod 681, a spiral rod 683, a baffle plate 682, and a fixed plate 684. The impurity discharge port 67 has a groove 7. The baffle plate 682 passes through the groove 7 and is slidably connected to it, serving to block the impurity discharge port 67. One end of the fixed rod 681 is fixedly connected to the impurity discharge port 67, and the other end is fixedly connected to the fixed plate 684. The spiral rod 683 passes through the fixed plate 684 and is threadedly connected to it. One end of the spiral rod 683 is rotatably connected to the baffle plate 682.

[0025] The above-described working process is as follows: Leachate enters the main tank 1 through the inlet pipe 2. At this time, the controller 3 activates one of the electric cylinders 4 to move the baffle 5, allowing the leachate to enter the discharge pipe 61. The leachate and impurities fall onto the filter plate 64. The impurities are intercepted and slide along the inclined filter plate 64, while the leachate passes through the filter plate 64 and is discharged. When impurities accumulate on the filter plate 64, the electric cylinder 4 is activated to block the discharge pipe 61 with the baffle 5. At this time, the motor 66 is activated to drive the cam 65 to rotate. The cam 65 contacts the filter plate 64, causing the filter plate 64 to vibrate. At this time, the spring 63 is compressed. When the cam 65 is no longer in contact with the filter plate 64, the spring 63 drives the filter plate 64 to reset, thus causing the filter plate 64 to vibrate. The vibration of the filter plate 64 shakes the impurities into the impurity discharge port 67. At this time, the screw rod 683 is rotated, causing the baffle 682 to continuously block the impurity discharge port 67, allowing the impurities to be discharged.

[0026] The above solution has the following advantages: the filter device 6 filters impurities, and the cam 65 contacts the filter plate 64, causing the filter plate 64 to vibrate and carry the impurities to the impurity discharge port 67. At this time, the control valve 68 is opened to discharge the impurities. The controller 3 controls the operation of the electric cylinder 4 to open or close the discharge pipe. When one of the discharge pipes is closed, the motor 66 is started to discharge the impurities, thereby preventing leachate from being discharged from the impurity discharge port 67.

[0027] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
