[0002] According to the "Hazardous Waste Landfill Pollution Control Standards" that will be implemented soon, when the site is located in a highly compressible silt, peat and soft soil area, or when the saturated permeability coefficient of the natural base layer does not meet the requirements, a rigid landfill with visual inspection function must be built; some other hazardous wastes, such as hazardous wastes with a total arsenic content greater than 5%, also need to be placed in a rigid landfill; therefore, the construction of rigid landfills will inevitably increase.

[0003] Most rigid landfills are above ground, more than 7m above the ground. Currently, there is no mature operating method to bury waste in rigid landfills.

[0004] Therefore, it is necessary to propose a device and method for semi-automatic landfill operation in a rigid landfill to at least partially solve the above problems. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a device for semi-automatic landfill operation in a rigid landfill, characterized in that the rigid landfill comprises at least one rigid landfill unit row, the rigid landfill unit row comprises at least one rigid landfill unit connected in sequence and having the same size and shape,

[0006] The equipment includes a loading platform, a track and a feeding device, wherein:

[0007] The loading platform is connected to one end of the rigid landfill unit row.

[0008] The track is arranged on two opposite sides of the top of the rigid landfill library unit row and its extension direction is the same as the extension direction of the rigid landfill library unit row.

[0009] The feeding device is arranged on the loading platform and can move from the loading platform to the top of any rigid landfill unit along the track, and fill the waste into the rigid landfill unit.

[0010] In one example, a movable top cover is further included, which is disposed on the top of the row of rigid landfill storage units and shares the track with the feeding device.

[0011] In one example, the movable top cover includes a panel and a driving wheel disposed below two opposite ends of the panel and connected to the panel.

[0012] The driving wheel is connected to a motor, and driven by the motor, the driving wheel rotates in the track, and the movable top cover moves on the top of the rigid landfill unit to cover the predetermined rigid landfill unit.

[0013] In one example, the removable roof includes an emergency stop brake and a parking brake handle.

[0014] In one example, railings are provided around the top of the movable top cover.

[0015] In one example, the loading platform includes a loading plate with a loading hole in the center of the loading plate, and the bottom of the feeding device is fixed at the four corners of the loading plate. During feeding, the waste passes through the loading hole.

[0016] In one example, the feeding device comprises a gantry crane.

[0017] In one example, the track comprises an electric single girder crane track.

[0018] In one example, a first monitor is further included. The bottom of the rigid landfill unit is higher than the ground. The first monitor is arranged between the bottom of the rigid landfill unit and the ground.

[0019] In one example, a second monitor is further included, and the second monitor is disposed on the feeding device.

[0020] The present invention also provides a method for semi-automatic landfill operation in a rigid landfill, characterized in that the rigid landfill comprises at least one rigid landfill unit row, the rigid landfill unit row comprises at least one rigid landfill unit connected in sequence and having the same size and shape,

[0022] The method comprises the following steps:

[0023] 1) transporting the waste to be landfilled to the bottom of the loading platform;

[0024] 2) starting the feeding device located on the loading platform, wherein the feeding device lifts the waste to be landfilled to a level higher than the top surface of the loading platform;

[0025] 3) The feeding device moves forward along the track to the top of any rigid landfill unit and fills the waste into the rigid landfill unit;

[0026] 4) The feeding device moves backward along the track until it returns to the loading platform, picks up new waste again, and performs landfilling operation again until the rigid landfill unit is filled with waste; and

[0027] 5) The feeding device performs the same operation as above to landfill the remaining rigid landfill units with waste until all the rigid landfill units in the rigid landfill unit row are filled with waste.

[0028] In one example, a movable top cover sharing the track with the feeding device is further provided on the top of the rigid landfill unit row.

[0052] It should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or combinations thereof. The singular forms "a", "an" and "said / the" are also intended to include plural forms, unless the context clearly indicates otherwise.

[0053] According to the "Hazardous Waste Landfill Pollution Control Standards" that will be implemented soon, when the site is located in a highly compressible silt, peat and soft soil area, or when the saturated permeability coefficient of the natural base layer does not meet the requirements, a rigid landfill with visual inspection function must be built; some other hazardous wastes, such as hazardous wastes with a total arsenic content greater than 5%, also need to be placed in a rigid landfill; therefore, the construction of rigid landfills will inevitably increase.

[0054] Most rigid landfills are above ground, more than 7m above the ground. Currently, there is no mature operating method to bury waste in rigid landfills.

[0055] The present invention provides a novel device and method for semi-automatic landfill operation in a rigid landfill, wherein a loading platform is arranged on one side of the top of a rigid landfill unit located at one end of a rigid landfill unit row, a feeding device is arranged on the loading platform, the feeding device and a movable top cover share a track arranged on the top of the rigid landfill unit row, the feeding device is movable on the track, the feeding device fills waste into the rigid landfill unit by moving along the track, and the movable top cover covers the top of a predetermined rigid landfill unit by moving along the track.

[0056] The present invention provides equipment and method for semi-automatic landfill operation in rigid landfills, which effectively saves manpower and performs landfill operation more safely and quickly. At the same time, the method can more effectively separate rainwater and sewage, and is convenient for operators to control.

[0057] Figure 1-Figure 8 A structural diagram of a device 200 for semi-automatic landfill operation in a rigid landfill according to an embodiment of the present invention is shown.

[0058] like Figure 1-Figure 3 As shown, the rigid landfill includes at least one rigid landfill unit row 100, and the rigid landfill unit row 100 includes n rigid landfill units 110 arranged side by side and having the same size and shape, n is greater than or equal to 1, and from the first rigid landfill unit 111 to the nth rigid landfill unit, the distance between the rigid landfill unit and the loading platform becomes farther and farther.

[0059] like Figure 1-Figure 3 and Figure 5-Figure 6As shown, the semi-automatic landfill operation equipment 200 includes a track 210, a loading platform 220 and a feeding device 230. The track 210 is arranged on two opposite sides of the top of the rigid landfill unit row 100, and its extension direction is the same as the extension direction of the rigid landfill unit row 100. The loading platform 220 is arranged on one side of the top of the rigid landfill unit located at one end of the rigid landfill unit row 100, that is, the loading platform 220 is connected to one end of the rigid landfill unit row 100 in the extension direction. At the beginning of feeding, the feeding device 230 is located on the loading platform 220, and the feeding device 230 is movable on the track 210. By moving along the track 210, the feeding device 230 fills the waste into any rigid landfill unit.

[0060] In one example, the track 210 is an electric single-beam crane track. In one example, the feeding device 230 includes a crane, and in one example, the feeding device 230 includes a gantry crane. In one example, the loading platform 220 includes a loading plate, and the center of the loading plate has a loading hole 221. The bottom of the feeding device 230 is fixed at the four corners of the loading plate. When feeding, the waste passes through the loading hole 221. The feeding device 230 is provided with an automatic unhooking device. When the waste drops to the bottom of the rigid landfill unit, the waste is automatically unhooked without the need for human assistance.

[0061] In one example, a movable top cover 240 (a steel structure movable canopy) is further included on a track 210 disposed on the top of the rigid landfill storage unit row 100, and the movable top cover 240 covers the top of the predetermined rigid landfill storage unit by moving along the track 210. In one example, the movable top cover 240 includes a panel and a driving wheel disposed below two opposite ends of the panel and connected to the panel, wherein the driving wheel is connected to a motor, and driven by the motor, the driving wheel rotates in the track 210, and the rainproof top cover moves on the top of the rigid landfill storage unit to cover the predetermined rigid landfill storage unit.

[0062] In one example, the removable roof 240 includes an emergency stop brake and a parking brake handle.

[0063] In one example, railings 241 (safety guardrails) are provided around the top of the movable top cover 240. Figure 7 and Figure 8 In this way, when the observer is located on the movable top cover 240 to perform observation and other operations, it can be safer.

[0064] In one example, a first monitor 250 (eg, Figure 6 and Figure 7 shown) and a second monitor (not shown).

[0065] In one example, the bottoms of n rigid landfill units are higher than the ground, and the first monitor 250 is disposed between the bottom of the rigid landfill unit and the ground, and when landfilling waste, the bottom of the rigid landfill unit is monitored by the first monitor 250. The first monitor 250 monitors whether there is leakage at the bottom of the rigid landfill unit.

[0066] In one example, the second monitor is disposed on the feeding device 230, and when the waste is landfilled, the landfilling condition is monitored by the second monitor. The second monitor monitors the landfilling condition inside the rigid landfill storage unit.

[0067] In one example, the first monitor 250 and the second monitor are movable carts loaded with cameras, that is, the first monitor 250 includes a first automatic video cart, and the second monitor includes a second automatic video cart. Of course, those skilled in the art can use other devices to monitor the bottom and interior of the rigid landfill storage unit. A monitor track is also provided below the bottom of the rigid landfill storage unit, and the first monitor 250 moves along the monitor track.

[0068] Figure 1-Figure 3 A schematic diagram showing specific operation steps of method a for semi-automatic landfill operation on a rigid landfill according to an embodiment of the present invention is shown.

[0069] In one example, the rigid landfill includes at least one rigid landfill unit row 100, which are arranged side by side, and there is a certain gap between adjacent rigid landfill unit rows 100. Multiple rigid landfill unit rows 100 form a rigid landfill unit matrix.

[0070] like Figure 1-Figure 3 As shown, each rigid landfill storage unit row 100 includes n rigid landfill storage units 110 connected in sequence and of the same size and shape, n is greater than or equal to 1, and from the first rigid landfill storage unit 111 to the nth rigid landfill storage unit, the distance between the rigid landfill storage unit and the loading platform becomes farther and farther.

[0071] In one example, a track 210 is provided on the top of the rigid landfill storage unit row 100, and the extension direction of the track 210 is the same as the extension direction of the rigid landfill storage unit row 100, and the track 210 is located on two opposite sides of the rigid landfill storage unit row 100. In one example, the track 210 is an electric single-beam crane track. A loading platform 220 is provided on one side of the top of the rigid landfill storage unit located at one end of each rigid landfill storage unit row 100, and a feeding device 230 is provided on the loading platform 220 when feeding is started.

[0072] Method a includes the following main steps:

[0073] 1) transporting the waste to be landfilled to the bottom of the loading platform 220;

[0074] In one example, after the forklift is loaded, the waste is transported to the bottom of the starting platform. In one example, the waste is packed into bags and the waste is packaged and transported in bags.

[0075] 2) Start the feeding device 230 located on the loading platform 220, and the feeding device 230 lifts the waste to be landfilled to a level higher than the top surface of the loading platform 220;

[0076] In one example, the loading platform 220 includes a loading plate with a loading hole 221 in the center of the loading plate, and the bottom of the feeding device 230 is fixed at the four corners of the loading plate. When the feeding device 230 lifts the waste, the bagged waste passes through the loading hole 221, and the waste passes through the loading hole 221 and is lifted by the feeding device 230 to a level higher than the top surface of the loading platform 220. In one example, the loading platform 220 is higher than the top of the rigid landfill unit, so that it is ensured that the waste can be higher than the top of the rigid landfill unit after passing through the loading hole 221, so as to facilitate the smooth filling of the waste into the rigid landfill unit.

[0077] In one example, the feeding device 230 includes a gantry crane, which is also called a gantry crane. A mobile gantry crane is used for lifting operations. After loading by a forklift, the cargo is transported to the bottom of the starting platform and lifted by a lifting machine. No manpower is required and only one reversal is required.

[0078] 3) If Figure 2 As shown, the feeding device 230 moves forward along the track 210 to the top of the first rigid landfill unit 111, and fills the waste into the first rigid landfill unit 111 in sequence;

[0079] The feeding device 230 is provided with an automatic unhooking device. When the waste drops to the bottom of the rigid landfill unit, the waste is automatically unhooked without the need for human assistance.

[0080] 4) The feeding device 230 moves backward along the track 210 until it returns to the loading platform 220 and picks up new waste again to perform another landfill operation until the first rigid landfill unit 111 is filled with waste.

[0081] In one example, after any of the rigid landfill units is filled with waste, the step 41 of covering the top of the rigid landfill unit with a sealing structure is also included. In one example, the step 41 of covering the sealing structure includes: 411), sequentially pressing cover plates on the top of the rigid landfill units filled with waste; 412), after all the rigid landfill units are filled with waste, laying concrete on all the cover plates for leveling; Figure 3In the embodiment, the first rigid landfill unit 111 is filled with waste and partially sealed (the step of pressing the cover plate has been performed). Of course, those skilled in the art will know that the sealing structure can be various and is not limited to the above-mentioned method, and the steps for setting the sealing structure are not limited to the above-mentioned order.

[0082] In one example, a 12 cm thick prefabricated reinforced concrete cover is used to cover the waste on top of the waste sealed with the HDPE film. After the landfill pool is completely filled, concrete is sprayed to level the slope to avoid water accumulation on the top of the pool. In one example, the thickness of the plain concrete is 8 cm.

[0083] In one example, the interior of the rigid landfill library cell is a cube or a cuboid.

[0084] In one example, before landfilling waste into a rigid landfill unit, the HDPE film (high-density polyethylene film) is first cut into four HDPE films with the same area and shape as the four inner walls of the rigid landfill unit, and then the two opposite sides of the four HDPE films are welded to the sides of other HDPE films, and then a piece of HDPE film with the same area and shape as the bottom wall of the rigid landfill unit is cut out, and then the four bottom sides of the welded HDPE film are welded to the four sides of the HDPE film cut out later, and the whole is placed in the rigid landfill unit, so that the HDPE film is close to the inner wall and bottom wall of the rigid landfill unit, and the whole HDPE film forms the anti-seepage layer of the pool wall of the rigid landfill unit.

[0085] In one example, when the waste fills up the rigid landfill unit, a HDPE film is laid on the top of the waste, and the four sides of the HDPE film are welded to the four exposed top edges of the top of the HDPE film as a whole to seal the waste.

[0086] 5) The feeding device 230 performs the same operation as above to landfill waste from the second rigid landfill unit to the nth rigid landfill unit until all the rigid landfill units in the rigid landfill unit row 100 are filled with waste, wherein, from the first rigid landfill unit 111 to the nth rigid landfill unit, the distance between the rigid landfill unit and the loading platform 220 becomes farther and farther.

[0087] Of course, those skilled in the art will appreciate that the order of filling the n rigid landfill units can be adjusted arbitrarily, and the order of filling the n rigid landfill units cannot be used as a condition to limit the protection scope of the present invention.

[0088] In one example, a movable top cover 240 (a steel structure movable canopy) sharing a track 210 with a feeding device 230 is also provided on the top of the rigid landfill storage unit row 100. When the feeding device 230 landfills the first rigid landfill storage unit 111, the movable top cover 240 moves to the second rigid landfill storage unit. When the feeding device 230 landfills the second rigid landfill storage unit, the movable top cover 240 moves to the third rigid landfill storage unit, and so on. When the rigid landfill storage unit at the end is filled, the movable top cover 240 is removed from the top of the rigid landfill storage unit.

[0089] In one example, when landfilling is interrupted (for example, when sudden weather changes such as rain or snow occur), the movable top cover 240 moves to the top of the rigid landfill unit corresponding to the landfill interruption. In this way, it is ensured that the waste in the unfilled rigid landfill unit is not mixed with rainwater, snow, etc., and rainwater and sewage are separated more effectively, which is convenient for operators to control.

[0090] In one example, the movable roof 240 (canopy) is made of stainless steel plate structure, which is fully enclosed to prevent rainwater from entering laterally during rainfall. At the same time, the stainless steel canopy has a large weight and good typhoon resistance. The roof material is made of stainless steel, with a load capacity of ≥2t; coverage area: 7.2×7.2m; railing 241 height: ≥1.5m; running speed (m / min): ≥25; track 210 width and wheel diameter: shared with cranes; noise: <60 decibels.

[0091] In one example, the removable roof 240 (canopy), in addition to the brakes during normal operation, is provided with an emergency stop brake and a parking brake handle to ensure parking in the event of an accident.

[0092] In one example, railings 241 are arranged around the top of the movable cover 240, which can be used to carry people and conduct operations. Observers are located on the movable cover 240 to observe the landfill situation.

[0093] In one example, the bottoms of n rigid landfill units are higher than the ground, and a first monitor 250 is arranged between the bottom of the rigid landfill unit and the ground, and when landfilling waste, the bottom of the rigid landfill unit is monitored by the first monitor 250. The first monitor 250 monitors whether there is leakage at the bottom of the rigid landfill unit.

[0094] In one example, a second monitor is provided on the feeding device 230, and when the waste is landfilled, the landfilling condition is monitored by the second monitor. The second monitor monitors the landfilling condition inside the rigid landfill unit.

[0095] In one example, the first monitor 250 and the second monitor use a movable trolley loaded with a camera. Of course, those skilled in the art may use other devices to monitor the bottom and interior of the rigid landfill unit. A monitor track is also provided below the bottom of the rigid landfill unit, and the first monitor 250 moves along the track 210. In one example, the monitoring range of the first monitor 250 is 170°.

[0096] Figure 4 A flow chart showing a method a for semi-automatic landfill operation on a rigid landfill according to an embodiment of the present invention.

[0097] In step 1), the waste to be landfilled is transported to the bottom of the loading platform 220;

[0098] In step 2), the feeding device 230 is started, and the feeding device 230 lifts the waste to be landfilled to a level higher than the top surface of the loading platform 220;

[0099] In step 3), the feeding device 230 moves forward along the track 210 to the top of the first rigid landfill unit 111 and fills the waste into the first rigid landfill unit 111 in sequence.

[0100] In step 4), the feeding device 230 moves backward along the track 210 until it returns to the loading platform 220, and picks up new waste again to perform another landfill operation until the first rigid landfill unit 111 is filled.

[0101] In step 5), the material device performs the same operation as above to landfill the second to nth rigid landfill units with waste, until all the sealed unit pool rigid landfill units in the rigid landfill unit row 100 are filled with waste.

[0102] Of course, those skilled in the art will appreciate that there may be multiple filling orders for the n rigid landfill units in the landfill method, and the order is not limited to the above-mentioned filling order, that is, the filling order for the n rigid landfill units cannot be used as a limitation on the scope of protection of the method of the present invention.

[0103] Using method a to fill the landfill in a rigid landfill, the following

[0104] Beneficial effects:

[0105] 1. Save raw materials. ① If a fixed canopy is used, the required coverage area is 7000m 2 , while the mobile canopy only needs to be arranged for 50m 2; ② The use of above-ground structures can reduce the surrounding blocking walls and reduce the amount of reinforced concrete; ③ The current visual inspection layer height is generally 2m (the observer goes to the visual inspection layer of the rigid landfill unit to observe whether there is leakage at the bottom of the rigid landfill unit). The use of video vehicles for inspection can reduce the layer height to 0.8m, reduce construction costs, reduce manpower inspections, and reduce the height of subsequent lifting operations.

[0106] 2. Reduce labor intensity. Use a mobile gantry crane for lifting operations. After the forklift loads the goods, it is transported to the bottom of the starting platform and lifted by the lifting machinery. No manpower is required and only one reverse transportation is required.

[0107] 3. Operation safety. Since the unit pool is not filled during operation, the personnel can only stand on the wall 40cm away, which poses a safety hazard. The steel cover canopy can provide an operating platform to ensure operation safety.

[0108] The purpose of the present invention is to provide a device and method for semi-automatic landfill operation in a rigid landfill, which can effectively save manpower and perform landfill operation more safely and quickly.

[0109] This method can separate rainwater and sewage more effectively and is easier for operators to control. The main contribution points are as follows:

[0110] (1) The gantry crane and the mobile awning share the same track.

[0111] (2) A stainless steel mobile canopy (with railings) is used as a standing platform during landfill operations.

[0112] (3) A starting platform is set at the end of the unit pool, which also serves as a platform for changing the track of the gantry crane and a loading platform.

[0113] (4) Use an automatic video vehicle to conduct inspections in the visual inspection room.

[0114] (5) The enclosure structure adopts the method of prefabricated cover plate + plain concrete.

[0115] The present invention provides a novel device and method for semi-automatic landfill operation in a rigid landfill, wherein a loading platform is arranged on one side of the top of a rigid landfill unit located at one end of a rigid landfill unit row, a feeding device is arranged on the loading platform, the feeding device and a movable top cover share a track arranged on the top of the rigid landfill unit row, the feeding device is movable on the track, the feeding device fills waste into the rigid landfill unit by moving along the track, and the movable top cover covers the top of a predetermined rigid landfill unit by moving along the track.

[0116] The present invention provides equipment and method for semi-automatic landfill operation in rigid landfills, which effectively saves manpower and performs landfill operation more safely and quickly.
