[0002] During the operation of garbage power generation equipment, the leachate in the incinerator directly enters the leachate collection pipeline through the collection hopper, and then directly enters the leachate collection tank through the flushing of a large flow of industrial water. Since there are a large number of filter residues in the leachate, it is easy to cause blockage of the leachate pipeline, resulting in low leachate treatment efficiency. At the same time, the amount of leachate is increased, leading to an increase in the consumption of production water and an increase in cost.

[0003] Therefore, how to improve the leachate treatment efficiency has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Utility Model

[0032] The core of the present utility model lies in providing a filtration device for a leachate collection hopper to improve the leachate treatment efficiency.

[0033] Another core of the present utility model lies in providing a waste treatment device having the above filtration device.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0035] During the operation of the waste-to-electricity generation equipment, the leachate in the incinerator directly enters the leachate collection pipeline through the collection hopper, and then directly enters the leachate collection tank through the flushing of a large flow of industrial water. Since there are a large number of filter residues in the leachate, it is easy to cause blockage of the leachate pipeline, resulting in a low leachate treatment efficiency. At the same time, the amount of leachate is increased, leading to an increase in the consumption of production water and an increase in costs.

[0036] In order to avoid blockage of the leachate pipeline, usually a drawer method is adopted at the lower part of the leachate collection hopper to separate water and filter residues. However, since the leachate collection hopper has a conical structure, the lower part of the leachate collection hopper has a small size, resulting in limited design size of the drawer, and the leachate is extremely easy to overflow from the pulling part.

[0037] For this reason, as Figures 1 to 4 shown, an embodiment of the present invention discloses a filtering device for a leachate collection hopper 200, including a box body 100. The accommodation cavity 102 formed by surrounding through the filtering hole mesh 101 of the box body 100 can leave the filter residues in the leachate in the accommodation cavity 102 by the filtering hole mesh 101 of the box body 100, thereby reducing the risk of blockage caused by the filter residues entering the leachate pipeline, improving the leachate treatment efficiency. At the same time, due to the reduction of the leachate volume, the consumption of production water is reduced and the cost is lowered.

[0038] Next, the filtering device for the leachate collection hopper 200 disclosed in the embodiment of the present invention will be specifically explained and described in conjunction with Figures 1 to 7 this.

[0039] As Figures 1 to 4 shown, the box body 100 includes a filtering hole mesh 101, and an accommodation cavity 102 is formed by surrounding through the filtering hole mesh 101. Among them, the box body 100 can adopt shapes such as a cuboid, a cylinder, a cone, etc. Of course, the accommodation cavity 102 formed by surrounding through the filtering hole mesh 101 can also adopt shapes such as a cuboid, a cylinder, a cone, etc. that are the same as the shape of the box body 100. At the same time, an opening 103 is provided on the box body 100 to facilitate the discharge of leachate into the accommodation cavity 102, so that the filter residues of the leachate are left in the accommodation cavity 102, thereby reducing the risk of blockage caused by the filter residues entering the leachate pipeline, improving the leachate treatment efficiency. At the same time, due to the reduction of the leachate volume, the consumption of production water is reduced and the cost is lowered.

[0040] In order to ensure that the filter residues of the leachate can be left in the accommodation cavity 102, the aperture of the filtering hole mesh 101 needs to be smaller than the diameter of the filter residues, and the aperture of the filtering hole mesh 101 should not be too small so that the leachate can flow out smoothly through the filtering hole mesh 101 and then enter the leachate collection pipeline.

[0041] To fix the filtering device within the leachate collection hopper 200, as Figures 5 to 7 shown, a limiting portion 104 is provided on the box body 100, and a supporting portion 201 is provided on the inner wall of the leachate collection hopper 200, such that the limiting portion 104 cooperates with the supporting portion 201 of the leachate collection hopper 200, thereby fixing the filtering device within the leachate collection hopper 200.

[0042] In some embodiments, as Figure 5 shown, there are two supporting portions 201 symmetrically arranged on the inner wall of the leachate collection hopper 200. The two supporting portions 201 can be inclined towards the central axis direction of the leachate collection hopper 200 to prevent filter residues from remaining on the supporting portions 201. At the same time, there are two limiting portions 104 on the box body 100, and they respectively correspond to the two supporting portions 201 on the inner wall of the leachate collection hopper 200. For the convenience of understanding, the three side edges where the supporting portion 201 is connected to the inner wall of the leachate collection hopper 200 are defined as connecting edges, and the side edge where the supporting portion 201 is not connected to the inner wall of the leachate collection hopper 200 is defined as the free edge. The free edges of the two supporting portions 201 are symmetrically arranged. Moreover, there is an opening for installing the filtering device between the free edges of the two supporting portions 201, and the distance between the free edges of the two supporting portions 201 is not greater than the maximum distance between the two limiting portions 104 on the box body 100, so that the two limiting portions 104 on the box body 100 can respectively support on the two supporting portions 201 of the leachate collection hopper 200, thereby fixing the filtering device within the leachate collection hopper 200.

[0043] In some embodiments, the distance H between the opening 103 of the box body 100 and the bottom of the manhole door 202 of the leachate collection hopper 200 can be 200 mm. At the same time, the horizontal distance L of the leachate collection hopper 200 at this position can be 2000 mm, and the width B of the leachate collection hopper 200 can be 190 mm. Among them, the supporting portion 201 can be made of a metal plate such as a steel plate and is welded and fixed to the inner wall of the leachate collection hopper 200. The supporting portion 201 is a rectangular structure, the thickness of the supporting portion 201 can be 3 mm, and the width of the supporting portion 201 is equal to the width B of the leachate collection hopper 200, that is, the width of the supporting portion 201 can be 190 mm, so that the supporting portion 201 can be fixed on three sides, ensuring the supporting strength. At the same time, the box body 100 can adopt a cuboid structure. To ensure that the filtering device can be installed in the leachate collection hopper 200 through the manhole door 202, as Figure 2 shown, the length l of the box body 100 can be 300 mm to 650 mm, and / or, the height h of the box body 100 can be 150 mm to 500 mm, to ensure that the filtering device can enter the leachate collection hopper 200 from the manhole door 202. And / or, as Figure 4As shown, the width b of the box body 100 is not greater than 190 mm so that the filtering device can be fixed within the leachate collection hopper 200.

[0044] Preferably, the length l of the box body 100 can be 400 mm, and the height h of the box body 100 can be 250 mm. Meanwhile, the width b of the box body 100 can be 190 mm to prevent the filter residue of the leachate from entering the leachate collection pipe through the gap between the box body 100 and the inner wall of the leachate collection hopper 200. At this time, the length of the support portion 201 can be 800 mm so that the limiting portion 104 on the box body 100 is fully supported on the support portion 201, improving the connection stability between the filtering device and the leachate collection hopper 200. Of course, when the support portion 201 is inclined, the length of the support portion 201 can be greater than 800 mm, and the specific length of the support portion 201 can be determined according to the inclination angle of the support portion 201.

[0045] As Figures 1 to 4 shown, in order to facilitate the disassembly and assembly of the filtering device, a lifting portion 105 is provided on the box body 100, so that when disassembling or installing the filtering device, a lifting device can move the filtering device to the installation position or remove it from the installation position through the lifting portion 105.

[0046] In some embodiments, as Figure 1 shown, the lifting portion 105 includes two symmetrically arranged lifting lugs 1051, and the lifting lugs 1051 can be welded to the box body 100, so that a lifting device can stably move the filtering device to the installation position or remove it from the installation position through the two lifting lugs 1051. Of course, the lifting portion 105 can also include four lifting rings arranged at the corners of the box body 100, and the lifting rings can be threadedly or welded to the box body 100, so that a lifting device can stably move the filtering device to the installation position or remove it from the installation position through the four lifting rings.

[0047] In some embodiments, as Figure 1 shown, the limiting portion 104 can adopt an L-shaped structure, and the limiting portion 104 has a first end and a second end arranged oppositely. The first end of the limiting portion 104 is connected to the outer wall of the box body 100, and the second end of the limiting portion 104 is supported on the support portion 201 of the leachate collection hopper 200. The limiting portion 104 can be continuously distributed along the width direction of the box body 100, as Figure 1 and Figure 4 shown, to increase the contact area between the limiting portion 104 and the support portion 201 and improve the connection stability between the filtering device and the leachate collection hopper 200. Of course, the limiting portion 104 can also be spaced along the width direction of the box body 100, which will not be elaborated herein.

[0048] Preferably, the second end of the limiting part 104 is on the same plane as the opening 103 of the box body 100, so as to avoid the accumulation of filter residues in the gap between the second end of the limiting part 104 and the box body 100, and at the same time facilitate the connection and fixation of the filtering device.

[0049] To fix the filter hole mesh 101, as Figures 1 to 4 shown, the box body 100 further includes a frame 106, and the filter hole mesh 101 is detachably arranged on the frame 106 so as to replace the damaged filter hole mesh 101.

[0050] In some embodiments, the filter hole mesh 101 can be made of a metal filter screen to ensure that the filter hole mesh 101 has a certain strength and improve the service life of the filtering device. At the same time, the filter hole mesh 101 can be fixed to the side and bottom surfaces of the frame 106 through fasteners to enclose and form a receiving cavity 102. To improve the strength of the frame 106 and at the same time increase the connection strength between the filter hole mesh 101 and the frame 106, pressing strips 1061 for fixing the filter hole mesh 101 are connected to two opposite side edges of the frame 106. The number of pressing strips 1061 on the same plane can be one, two, three or more, and the pressing strips 1061 can be arranged in a cross pattern, and the included angle can be 45°, 60°, 90°, etc., or can be arranged in parallel, which is not limited herein.

[0051] The embodiment of the present utility model also discloses a garbage treatment device, which includes a leachate collection hopper 200 and a filtering device arranged in the leachate collection hopper 200. The filtering device is the filtering device for the leachate collection hopper disclosed in the above embodiment, so it has all the technical effects of the above filtering device, which will not be elaborated herein.
