Description

Technical Field

[0001] This application relates to the field of filtration device technology, such as a drainage grate reinforcement device. Background Technology

[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.

[0003] In the field of waste-to-energy incineration, the waste storage area, as the core area for waste fermentation and leachate drainage, directly affects the system stability due to the way its sidewall drainage grates are fixed. Current technology commonly uses expansion bolts to directly anchor the drainage grates to the inner wall of the waste storage area. This design has the following technical drawbacks: the expansion bolts are exposed to leachate containing high concentrations of organic acids and salts for extended periods, making them prone to electrochemical corrosion and stress corrosion cracking, leading to thread engagement failure and reduced preload. Furthermore, because the fixing points are located on the inner wall of the waste storage area, replacement requires clearing the accumulated waste around the grates beforehand (usually requiring a 2-3 day shutdown), making replacement cumbersome. Summary of the Invention

[0004] This application provides a drainage grate reinforcement device. By combining and installing a first fixing plate and a second fixing plate, the fixing points of the expansion bolts avoid the area directly flushed by leachate, thereby reducing the corrosion rate of metal parts and extending the life of the device. The drainage grate is not directly fixed to the inner wall of the garbage bin, so it can be disassembled and replaced without emptying the garbage during replacement, shortening maintenance time and reducing downtime losses.

[0005] A drainage grate reinforcement device includes: a first fixing plate and a second fixing plate;

[0006] The first fixing plate is set parallel to the side wall of the garbage bin, and the number of plates corresponds one-to-one with the side of the drainage grate. One side of the plate is connected to the drainage grate, and the other side is connected to the side wall of the garbage bin.

[0008] By combining the first and second fixing plates, the fixing points of the expansion bolts are positioned to avoid areas directly flushed by leachate, reducing the corrosion rate of metal parts and extending the life of the device. The drainage grate is not directly fixed to the inner wall of the waste bin, allowing it to be disassembled and replaced without emptying the waste during replacement, thus shortening maintenance time and reducing downtime losses.

[0009] In some embodiments, the length and width of the drainage grate are smaller than the corresponding dimensions of the leachate channel, and the drainage grate is connected to the side of the first fixing plate facing the channel.

[0010] In some embodiments, the first fixing plate is connected to the side wall of the waste bin by a first expansion bolt.

[0011] In some embodiments, the first fixing plate is connected to the drainage grate by stainless steel bolts or stainless steel expansion screws.

[0012] In some embodiments, the second fixing plate is connected to the leachate channel by a second expansion screw, and the second expansion screw is spaced apart from the bottom side of the drainage grate and / or the landfill leachate channel.

[0013] In some embodiments, the drainage grate reinforcement device further includes: a third fixing plate and a fourth fixing plate;

[0014] The third fixing plate is connected to any inner wall of the leachate channel;

[0015] The fourth fixing plate is set perpendicular to the drainage grate, with one end abutting against the side wall of the drainage grate facing the leachate channel, and the other end connected to the third fixing plate.

[0016] In some embodiments, one end of the third fixing plate abuts against or is fixedly connected to the second fixing plate.

[0033] The shape of the drainage grate is set according to the shape of the leachate channel. The leachate channel can be polygonal. In the figure, the leachate channel is a rectangular channel, and the drainage grate is a rectangular metal plate.

[0034] Combination Figure 1-7 As shown, this embodiment of the present disclosure provides a drainage grate reinforcement device, including: a first fixing plate 2 and a second fixing plate 6;

[0035] The first fixing plate 2 is set parallel to the side wall 1 of the garbage bin, and the number of them corresponds one-to-one with the side of the drainage grate 5. One side of the first fixing plate is connected to the drainage grate 5, and the other side is connected to the side wall 1 of the garbage bin. As shown in the figure, there are four first fixing plates 2, which are respectively connected to the four sides of the drainage grate 5. The length of the first fixing plate 2 is cut according to actual needs. The first fixing plate 2 is a rectangular metal plate with a certain thickness and is made of anti-corrosion material. A sealing gasket is provided between the contact surfaces of the first fixing plate 2 and the drainage grate 5. The sealing gasket can be a rubber gasket or a silicone gasket. A sealing adhesive layer or sealing gasket is provided between the contact surfaces of the first fixing plate 2 and the side wall 1 of the garbage bin. The sealing adhesive layer can be formed by applying a sealing structural adhesive.

[0036] The second fixing plate 6 is arranged parallel to any inner wall of the leachate channel 9, corresponding one-to-one with the first fixing plate 2. One end of the second fixing plate 6 is fixedly connected to the middle position of the first fixing plate 2, and the other end is connected to the leachate channel 9. A sealant layer is provided between the contact surfaces of the second fixing plate 6 and the leachate channel 9. The sealant prevents leachate from seeping into the expansion screws and corroding their interior, thus preventing loosening. Optionally, the first fixing plate 2 and the second fixing plate 6 can be combined to form a T-shaped steel structure.

[0037] Optionally, the two ends of the second fixing plate 6 are embedded in the side wall 1 of the waste compartment.

[0038] By combining and installing the first fixing plate 2 and the second fixing plate 6, the fixing points of the expansion bolts are positioned to avoid the area directly flushed by leachate, thereby reducing the corrosion rate of metal parts and extending the life of the device. The drainage grate 5 is not directly fixed to the inner wall of the garbage bin, allowing it to be disassembled and replaced without emptying the garbage during replacement, thus shortening maintenance time and reducing downtime losses.

[0039] In some embodiments, the length and width of the drainage grate 5 are smaller than the corresponding dimensions of the leachate channel 9, and the drainage grate 5 is connected to the side of the first fixing plate 2 facing the channel. With this design, the drainage grate 5 can be removed from the leachate channel 9 after being disconnected from the first fixing plate 2, and can be replaced between the channels.

[0040] In some embodiments, the first fixing plate 2 is connected to the side wall 1 of the waste bin by a first expansion screw 3.

[0041] In some embodiments, the first fixing plate 2 is connected to the drainage grate 5 by stainless steel bolts 4 or stainless steel expansion screws.

[0042] In some embodiments, the second fixing plate 6 is connected to the leachate channel 9 by a second expansion screw, which is spaced apart from the bottom side of the drainage grate 5 and / or the landfill leachate channel 9. This spacing prevents leachate from flowing onto the expansion screw.

[0043] In some embodiments, the drainage grate reinforcement device further includes: a third fixing plate 7 and a fourth fixing plate 8;

[0044] The third fixing plate 7 is connected to any inner wall of the leachate channel 9;

[0045] The fourth fixing plate 8 is installed perpendicular to the drainage grate 5. One end of the plate abuts against the side wall of the drainage grate 5 facing the leachate channel 9, and the other end is connected to the third fixing plate 7. The drainage grate 5 has multiple filter holes on its surface, resulting in a slightly lower structure and gaps. The fourth fixing plate 8 is fixed at one end and abuts against the drainage grate 5 at the other end for support. The fourth fixing plate 8 provides rigid restraint to the side wall of the drainage grate 5, effectively resisting the lateral thrust generated by garbage accumulation and preventing the grate from tipping over or shifting. A sealing gasket or sealant layer is provided between the contact surfaces of the third fixing plate 7 and the leachate channel 9.

[0046] In some embodiments, one end of the third fixing plate 7 abuts against or is fixedly connected to the second fixing plate 6. This can provide support for the second fixing plate 6.
