Description

Technical Field

[0001] The invention relates to the field of garbage bin drainage, and in particular to a garbage bin drainage grille and application thereof. Background Art

[0002] After the garbage storage bin of the municipal domestic waste incineration power plant was put into use for 5-6 years, the bottom of the garbage bin could not be cleaned due to equipment limitations. At the same time, a large amount of domestic garbage (plastic bags) poured into the drainage steel grilles on the upper and lower layers, causing serious blockage. This situation seriously affected the drainage of the leachate in the garbage bin, resulting in a large amount of leachate in the bin for a long time. This not only had an adverse effect on the normal operation of the garbage bin, but also caused serious interference to the operation of the entire production system. Once a blockage occurs, staff are required to clean it. In serious cases, it is even necessary to replace the grille, which requires huge maintenance costs. In addition, blockages are relatively common, and staff are often required to clean it, which seriously affects work efficiency. Summary of the invention

[0003] In order to solve the problems existing in the background technology, the present invention provides a garbage bin drainage grille which can reduce the number of times the water grate is cleaned, improve intrinsic safety work, and reduce maintenance costs.

[0004] In response to the problems in the prior art, the present invention provides a garbage bin drainage grille, including a screen, wherein the connecting bamboo blocks are provided with multiple groups of notches, the connecting bamboo blocks are clamped on bamboo strips, the length of the connecting bamboo blocks is 0.8 meters, the bamboo strips are clamped in the notches provided on the connecting bamboo blocks, each group of the bamboo strips corresponds to a group of notches, the length of the bamboo strips is 1.2 meters, the first grille is formed by four groups of connecting bamboo fences clamped together, the second grille is formed by three groups of connecting bamboo fences clamped together, and the third grille is formed by two groups of connecting bamboo fences clamped together.

[0005] Specifically, the first grille, the second grille and the third grille are installed and positioned in three layers, namely, four rows on the lower layer, three rows on the middle layer and two rows on the upper layer, in front of the screen in the garbage bin.

[0006] Specifically, after the first grid is laid and passed the acceptance, the second grid is laid. The second layer is laid in three rows in total. The three rows of connecting bamboo fences are laid vertically with a laying width of 3.6 meters. The laying process needs to be kept flat, with staggered seams on the same layer and pressed seams on different layers, and the layers must be assembled tightly.

[0007] Specifically, the third grille is laid in two rows, and the two rows of connecting bamboo fences are laid horizontally with a laying width of 1.6 meters. A slide groove is provided at the contact position between the third grille and the second grille, and a slider is fixedly installed at the contact position between the second grille and the third grille, and the slider and the slide groove are slidably connected.

[0008] Specifically, the first grille and one side of the screen fit together, the other side of the first grille and one side of the second grille fit together, and the other side of the second grille and one side of the third grille fit together, with certain gaps between them.

[0009] Specifically, a plurality of slots are fixedly provided at one end of the bamboo fence, and a plurality of connection blocks are fixedly installed at the other end of the bamboo fence, and the slots and the connection blocks are slidably connected.

[0010] The present invention also provides an application of a garbage bin drainage grille in a garbage bin.

[0011] Beneficial effects of the present invention:

[0012] (1) A garbage bin drainage grille and its application of the present invention has multiple groups of grilles installed at the front end of the screen. The first layer has four rows in total, the second layer has three rows in total, and the third layer has two rows in total. During the laying process, the grilles need to be kept flat, with staggered seams on the same layer and compressed seams on different layers. The grilles are tightly assembled to effectively reduce the water level in the garbage bin, increase the calorific value of the garbage entering the furnace and reduce the moisture content of the garbage. After the normal backflow of the leachate in the garbage bin is stable, the number of full-time maintenance personnel entering the leachate corridor to clean the water grates can be effectively reduced, thereby fundamentally eliminating high-frequency limited space operations and greatly reducing the safety risks of operations.

[0013] (2) After laying the grating, it can ensure that the steel grating in the leakage corridor will not be blocked by garbage, and the water grate cleaning work is basically eliminated. At the same time, through bamboo fence isolation and filtration, garbage, sludge and other debris are directly blocked from the source to the leachate corridor, which can effectively keep the site clean and tidy.

[0020] In order to make the technical methods, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 and Figure 2 as well as Figure 4 As shown, a garbage bin drainage grille includes a screen 1, the connecting bamboo block 510 has multiple groups of slots, the connecting bamboo block 510 is clamped on the bamboo strips 511, the length of the connecting bamboo block 510 is 0.8 meters, the bamboo strips 511 are clamped in the slots opened on the connecting bamboo block 510, each group of the bamboo strips 511 corresponds to a group of slots, the length of the bamboo strips 511 is 1.2 meters, the first grille 2 is formed by four groups of connecting bamboo fences 5 clamped together, the second grille 3 is formed by three groups of connecting bamboo fences 5 clamped together, and the third grille 4 is formed by two groups of connecting bamboo fences 5 clamped together, which can effectively reduce the full-time maintenance personnel entering the leachate corridor to clean the water grate, fundamentally eliminate high-frequency limited space operations, and greatly reduce the safety risks of operations.

[0022] like Figure 3As shown, the installation method and position of the first grille 2, the second grille 3, and the third grille 4 are laid in front of the screen 1 in the garbage bin in three layers, namely, four rows are laid in the lower layer, three rows are laid in the middle layer, and two rows are laid in the upper layer. After the first grille 2 is laid and passed the acceptance, the second grille 3 is laid. A total of three rows are laid in the second layer, and the three rows of connected bamboo fences 5 are all laid vertically with a laying width of 3.6 meters. During the laying process, it is necessary to keep it flat, with staggered seams on the same layer and pressed seams on different layers, and the assembly is tight. A total of two rows of the third grille 4 are laid, and the two rows of connected bamboo fences 5 are all laid horizontally with a laying width of 1.6 meters. A slide groove 512 is provided at the contact position between the third grille 4 and the second grille 3, and the contact position between the second grille 3 and the third grille 4 is fixedly installed There is a slider 513, and the slider 513 is slidably connected to the slide groove 512. The first grille 2 and one side of the screen 1 fit together, the other side of the first grille 2 and one side of the second grille 3 fit together, and the other side of the second grille 3 and one side of the third grille 4 fit together, with a certain gap between them. One end of the bamboo fence 5 is fixed with multiple groups of slots 514, and the other end of the bamboo fence 5 is fixed with multiple groups of connecting blocks 515. The slots 514 and the connecting blocks 515 are slidably connected to ensure that the steel grille in the seepage corridor will not be blocked by garbage, and the water grate cleaning work is basically eliminated. At the same time, through the isolation and filtration of the bamboo fence, garbage, sludge and other debris are directly blocked from the source to conduct the seepage corridor, which can effectively keep the site clean and tidy.

[0023] The present invention also provides an application of a garbage bin drainage grille in a garbage bin.

[0024] (1) The bamboo strips 511 in the present invention are selected to be bamboo strips with a width of 5 cm and a length of 120 cm, and the bamboo fence 5 is a standard 0.8-meter wide and 1.2-meter long. The plate-type bamboo fence is then combined into a square bundled bamboo fence with a height of 0.8 meters. This square bundled bamboo fence is laid in front of the steel grille of the garbage bin in three layers, namely, 4 rows are laid in the lower layer, 3 rows are laid in the middle layer, and 2 rows are laid in the upper layer. When fresh domestic garbage is dumped and piled on the bamboo fence, the precipitated leachate is filtered layer by layer through the upper, middle and lower layers of bamboo strips. A large amount of impurities are filtered on the surface of the upper bamboo fence. The leachate flows to the bottom of the bin through the 1-cm gap between the bamboo strips and is discharged into the leachate gallery through the steel grille at the bottom of the bin. The above method can effectively avoid the deposition of garbage at the bottom of the bin, and at the same time has a good filtering effect on the leachate discharged into the collection system.

[0025] (2) In the present invention, the first grid 2 is laid first, and the same layer must be laid tightly together and closely fit with the garbage bin grate. The first layer is laid in four rows, the first two rows are laid horizontally (i.e., the long sides of the first two rows are laid parallel to the grate), and the last two rows are laid vertically (i.e., the long sides of the last two rows are laid vertically to the grate). The laying width is 4.0 meters, and the height of each layer of bamboo fence in the free state is about 0.8 meters.

[0026] (3) After the first grid 2 is laid and passed the acceptance, the second grid 3 is laid. The second layer is laid in three rows in total. The three rows 5 are all laid vertically (that is, the long side is laid perpendicular to the water grate), with a laying width of 3.6 meters. During the laying process, it is necessary to keep it flat, stagger the seams on the same layer, press the seams on different layers, and assemble them tightly.

[0027] (4) The third grid 4 is laid in two rows, and both rows of bamboo fences 5 are laid horizontally (i.e., the long side is laid parallel to the water grate), with a laying width of 1.6 meters. Laying layer by layer according to the above requirements can cover the joint gap between the middle and lower bamboo fences, preventing part of the domestic garbage from entering the joint gap during unloading and affecting the filtration area, thereby ensuring and extending the use effect of the bamboo fence;

[0028] It can effectively reduce the water level in the garbage bin, increase the calorific value of the garbage entering the furnace and reduce the moisture content of the garbage. It is a necessary means and an important link to ensure the normal and efficient incineration of garbage. It is also a necessary means to increase the power generation per ton of garbage, reduce the power consumption rate of the plant, and reduce the unit consumption of fuel / gas. After the normal backflow of the leachate in the garbage bin is stable, it can effectively reduce the full-time maintenance personnel entering the leachate corridor to clean the water grate, fundamentally eliminate high-frequency limited space operations, and greatly reduce the safety risks of operations. After laying the grid, it can ensure that the steel grid in the leachate corridor will not be blocked by garbage, and the water grate cleaning work is basically eliminated. At the same time, through the isolation and filtration of the bamboo fence 5, garbage, sludge and other debris are directly blocked from the source to enter the leachate corridor, which can effectively keep the site clean and tidy.

[0029] It can also reduce the SS and conductivity of the raw leachate, which is a prerequisite for ensuring the stable operation of the leachate system. After the garbage bin is cleaned, the water flow from the collection tank to the leachate treatment system is more stable, and the raw liquid SS and conductivity have a downward trend, which can effectively reduce the load of the anaerobic system.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention.
