[0038] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0039] Combine the following Figures 1 to 9 A soil disposal system according to an embodiment of the present invention is described.

[0040] The vehicle-mounted slag treatment system of the embodiment of the present invention includes a first vehicle 01, a screening device 1, a second vehicle 02, a sand washing device 2, a third vehicle 03, a conditioning device 4, a fourth vehicle 04, a filter press device 3, a fifth vehicle 05 and a water treatment device 5.

[0041] The screening device 1 is provided on the first vehicle 01, and the screening device 1 is suitable for screening the slag into crushed stone and mortar. Specifically, the screening device 1 is connected to the first vehicle 01, and the first vehicle 01 can move the screening device 1 to a set site. The screening device 1 includes a hopper and a drum screen.

[0042] The slag enters the screening device 1 through the feed hopper, the screening device 1 adds water to the slag to mix the water and the slag, the soil, sand and water in the slag are mixed to form mortar, the screening device 1 separates the debris such as crushed stone and garbage in the slag that are not easy to form mortar from the mud, and transports the crushed stone out of the slag processing system of the embodiment of the present invention to recycle the crushed stone.

[0043] The sand washing device 2 is arranged on the second vehicle 02, and the sand washing device 2 includes a sand washing component 22 and a dehydration component 23. The sand washing component 22 is suitable for processing mortar into sand and mud, and the dehydration component 23 is suitable for dehydrating sand.

[0044] Specifically, the sand washing device 2 is connected to the second vehicle 02, and the second vehicle 02 can move the sand washing device 2 to a set site. The sand washing component 22 can separate the sand and gravel particles in the mud produced by the screening component 11 from the mud, so as to facilitate the recycling of the sand and gravel in the slag.

[0045] The conditioning device 4 is provided on the third vehicle 03, and the conditioning device 4 is suitable for conditioning the mud. Specifically, the conditioning device 4 is connected to the third vehicle 03, and the third vehicle 03 can move the conditioning device 4 to a set site. The conditioning device 4 is suitable for conditioning the mud produced by the sand washing device 2, thereby increasing the concentration of the mud, so as to facilitate the filter press device 3 to perform filter press treatment on the mud.

[0046] The conditioning device 4 is connected to the water treatment device 5. When the conditioning device 4 performs conditioning treatment on the mud, a supernatant is produced. The supernatant is transported to the water treatment device 5 and recovered.

[0047] The filter press device 3 is arranged on the fourth vehicle 04, and the filter press device 3 is suitable for filtering the mud into mud cake and filtrate. Specifically, the filter press device 3 is connected to the fourth vehicle 04, and the fourth vehicle 04 can move the filter press device 3 to a set site. The filter press device 3 is a diaphragm plate and frame filter press. The filter press device 3 places the mud in a high-pressure diaphragm filter bag, and then pressurizes the high-pressure diaphragm filter bag to squeeze the mud so as to separate the soil and water in the mud, thereby forming a mud cake and filtrate.

[0048] The vehicle-mounted slag handling system of the embodiment of the present invention transports various parts of the vehicle-mounted slag handling system of the embodiment of the present invention to the vicinity of the construction site by setting up a first vehicle 01, a second vehicle 02, a third vehicle 03 and a fourth vehicle 04. Near the construction site, the screening device 1, the sand washing device 2, the conditioning device 4, and the filter press device 3 are detachably connected by pipelines, and the slag produced at the construction site is processed.

[0049] Therefore, on the one hand, the vehicle-mounted muck handling system of the embodiment of the present invention can be transported to the vicinity of the construction site by vehicle and assembled, which shortens the transportation distance of the muck and reduces the transportation cost of the muck; on the other hand, the vehicle-mounted muck handling system of the embodiment of the present invention is transported to the vicinity of the construction site by vehicle and connected, and there is no need to set up a flat station site, thereby reducing the layout cost of the vehicle-mounted muck handling system of the embodiment of the present invention.

[0050] In addition, the vehicle-mounted slag processing system of the embodiment of the present invention processes the slag into recyclable gravel and sand, so that part of the slag can be recycled and the cost of transporting the slag is reduced. Therefore, the vehicle-mounted slag processing system of the embodiment of the present invention has the advantages of being easy to be arranged near the construction site and having a low installation cost.

[0051] In some embodiments, the screening device 1 includes a lifting assembly 12 and a screening assembly 11 , the screening assembly 11 has a storage state and a working state, and the lifting assembly 12 is suitable for driving the screening assembly 11 to switch from the storage state to the working state.

[0052] Specifically, Figure 1 and Figure 2 As shown, the lifting assembly 12 is located at the lower side of the screening assembly 11, and the lifting assembly 12 includes a column 121 and a driver 122. The column 121 is located at the rear of the first vehicle 01 and is rotatably connected to the screening assembly 11. One end of the driver 122 is rotatably connected to the first vehicle 01, and the other end of the driver 122 is rotatably connected to the screening assembly 11. The length of the driver 122 is adjustable so as to drive the screening assembly 11 to rotate relative to the first vehicle 01, thereby switching the screening assembly 11 between a storage state and a working state.

[0053] Therefore, on the one hand, the inclination angle of the screening component 11 relative to the first vehicle 01 can be adjusted by adjusting the length of the driver 122, so as to facilitate the screening component 11 to screen the screened materials of different particle sizes. On the other hand, the driver 122 can lift the screening component 11 in the working state to screen the debris, and reduce the height of the screening component 11 to the minimum in the storage state, thereby improving the passability of the first vehicle 01 and the screening device 1.

[0054] In some embodiments, the sand washing device 2 has a feed end 21 , and the screening device 1 has a discharge end 13 . The discharge end 13 of the screening device 1 can be overlapped above the feed end 21 of the sand washing device 2 .

[0055] Specifically, Figure 2 As shown, the sand washing device 2 includes a spiral sand washing machine, and the feed end 21 of the sand washing device 2 is the feed end 21 of the spiral sand washing machine. The spiral sand washing machine is arranged at an angle to screen the sand and mud in the slag by gravity. The height of the feed end 21 of the sand washing device 2 is lower than the discharge end 13 of the screening device 1.

[0056] When the sand washing device 2 and the screening device 1 are spliced, the discharge end 13 of the screening device 1 is located on the upper side of the feed end 21 of the sand washing device 2, so that the mortar flowing out of the screening device 1 flows into the sand washing device 2 under the action of gravity. Therefore, in the process of transporting the mortar from the screening device 1 to the sand washing device 2, no equipment pumping is required, which reduces the power consumption of the slag processing system of the embodiment of the present invention, thereby reducing the operating cost of the slag processing system of the embodiment of the present invention.

[0057] In some embodiments, the sand washing device 2 includes a cyclone 24 , which is connected between the sand washing assembly 22 and the conditioning device 4 . The cyclone 24 is suitable for separating fine sand from the mud and transporting it to the dewatering assembly 23 .

[0058] Specifically, the sand washing component 22 is suitable for separating the coarse sand and medium sand with larger particle size in the mortar from the mortar under the action of water flow, and conveying the mixture of washed sand and mud in the mortar to the cyclone 24. The cyclone 24 further separates the fine sand and mud under the action of centrifugal force, thereby separating the fine sand in the mortar from the mortar.

[0059] Thus, the cyclone 24 separates the sand and gravel particles in the mud with a small amount of sand and gravel particles filtered out in the sand washing component 22 from the mud to form fine sand and sends the fine sand to the dehydration component 23. On the one hand, it improves the sand and gravel production of the vehicle-mounted slag treatment system of the embodiment of the present invention when treating slag, and on the other hand, it reduces the sand and gravel content in the mud, avoiding the sand and gravel in the mud from affecting the mud conditioning or the operation of the filter press 3.

[0060] In some embodiments, the sand washing component 22 includes a first sand washing component 221 and a second sand washing component 222. The second sand washing component 222 is connected between the first sand washing component 221 and the dewatering component 23 to be suitable for fine washing of sand and gravel produced by the first sand washing component 221. The first sand washing component 221 is connected to the cyclone 24, and the second sand washing component 222 is connected to the cyclone 24.

[0061] Specifically, the first sand washing component 221 is a spiral sand washing machine, and the second sand washing component 222 is an impeller sand washing machine. After being processed by the first sand washing component 221, the mortar enters the second sand washing component 222. The second sand washing component 222 finely processes the mortar roughly processed in the first sand washing component 221. The first sand washing component 221 and the second sand washing component 222 are both connected to the cyclone 24, and the mud in the mortar is sent to the cyclone 24 for cyclone treatment.

[0062] Thus, the mortar is processed in two stages by the first sand washing component 221 and the second sand washing component 222, which reduces the mud carried on the sand and gravel particles in the dehydration component 23, improves the cleanliness of the sand and gravel, and facilitates the recycling of the sand and gravel.

[0063] In some embodiments, the conditioning device 4 includes a dosing component 41 and a flocculation component 42. The dosing component 41 is connected between the flocculation component 42 and the sand washing device 2. The dosing component 41 is suitable for adding agents to the mud and stirring it, and the flocculation component 42 is suitable for flocculating and settling the mud.

[0064] Specifically, Figure 6 and Figure 7As shown, the conditioning device 4 has a transport form and an expanded form. In the transport form, the dosing component 41 and the flocculation component 42 extend along the length direction of the fourth vehicle 04 and are connected end to end. In the expanded form, the dosing component 41 and the flocculation component 42 extend in the vertical direction and are arranged in parallel, and the dosing component 41 and the flocculation component 42 are connected to transport the sludge treated with dosing in the dosing component 41 to the flocculation component 42 for flocculation treatment.

[0065] Therefore, the height of the conditioning device 4 in the transport form is relatively low, which is convenient for installation on the fourth vehicle 04 for transportation, thereby improving the passability of the fourth vehicle 04 and the conditioning device 4. In the expanded form, the dosing component 41 and the flocculation component 42 are arranged vertically, which is convenient for utilizing the height of the dosing component 41 to perform dosing and stirring treatment on the mud and utilizing the height of the flocculation component 42 to perform flocculation treatment on the mud.

[0066] In some embodiments, at least part of the water treatment device 5 is disposed in the fifth vehicle 05 , and the water treatment device 5 is suitable for purifying the filtrate and supplying water to the screening device 1 and the sand washing device 2 .

[0067] Specifically, part of the water treatment device 5 is connected to the fifth vehicle 05, and the fifth vehicle 05 can move the part of the water treatment device 5 to a set site.

[0068] Therefore, the water treatment device 5 is connected to the filter press device 3 to purify the filtrate produced by the filter press device 3, and the purified filtrate is transported to the screening device 1 and the sand washing device 2 for reuse.

[0069] In some embodiments, the water treatment device 5 includes a sedimentation tank 51, a water reservoir 52 and a backup water tank 53. The sedimentation tank 51 is connected between the water reservoir 52 and the filter press device 3. The sedimentation tank 51 is suitable for precipitating the filtrate into clean water. The water reservoir 52 is suitable for storing clean water. The backup water tank 53 is connected to the water reservoir 52 to adjust the amount of water in the water reservoir 52.

[0070] Specifically, Figure 8 and Fig. 9 As shown, the sedimentation tank 51 is connected to the water storage tank 52, and the filtrate produced in the filter press device 3 flows slowly in the sedimentation tank 51. A small amount of soil particles in the filtrate are deposited at the bottom of the sedimentation tank 51 under the action of gravity, thereby obtaining cleaner water. The water in the sedimentation tank 51 flows to the water storage tank 52 for storage and recycling. The standby water tank 53 can be connected to a clean water source to reserve a certain amount of clean water. The standby water tank 53 is connected to the water storage tank 52.

[0071] Thus, the sedimentation tank 51 can process the filtrate produced by the filter press device 3 into clean water and recycle it, which reduces the water consumption of the vehicle-mounted slag treatment system of the embodiment of the present invention, thereby reducing the operating cost of the vehicle-mounted slag treatment system of the embodiment of the present invention. When the amount of water in the water reservoir 52 is small, the standby water tank 53 can supply water to the water reservoir 52 to ensure that the water treatment system continues to work stably.

[0072] In some embodiments, the sedimentation tank 51 includes a first sedimentation tank 511 and a second sedimentation tank 512, the second sedimentation tank 512 is connected between the first sedimentation tank 511 and the water reservoir 52, the water reservoir 52 is connected to the conditioning device 4 to be suitable for supplying water to the conditioning device 4, and the second sedimentation tank 512 is connected to the sand washing assembly 22 and the screening device 1.

[0073] Specifically, the sedimentation tank 51 includes a first sedimentation tank 511 and a second sedimentation tank 512. The second sedimentation tank 512 is arranged downstream of the first sedimentation tank 511. The filtrate produced in the filter press device 3 passes through the first sedimentation tank 511 and the second sedimentation tank 512 in sequence for sedimentation treatment. The second sedimentation tank 512 is connected to the sand washing component 22 and the screening device 1 to supply water to the sand washing component 22 and the screening device 1.

[0074] Therefore, the cleanliness of the liquid in the second sedimentation tank 512 is higher than that of the liquid in the first sedimentation tank 511. The second sedimentation tank 512 supplies water to the sand washing assembly 22 and the screening device 1, thereby preventing the water with a high mud content in the first sedimentation tank 511 from flowing back into the sand washing assembly 22 and the screening device 11, thereby improving the cleanliness of the water supplied by the sedimentation tank 51 to the sand washing assembly 22 and the screening device 1, thereby improving the working efficiency of the screening device 1 and the sand washing device 2.

[0075] In some embodiments, the vehicle-mounted slag treatment system includes a sixth vehicle 06 , a first sedimentation tank 511 and a second sedimentation tank 512 are arranged on the fifth vehicle 05 , and a water storage tank 52 and a backup water tank 53 are arranged on the sixth vehicle 06 .

[0076] Specifically, Figure 8 and Fig. 9 As shown, the vehicle-mounted slag treatment system of an embodiment of the present invention includes a sixth vehicle 06, the first sedimentation tank 511 and the second sedimentation tank 512 in the water treatment device 5 are arranged on the fifth vehicle 05, and the water storage tank 52 and the backup water tank 53 in the water treatment device 5 are arranged on the sixth vehicle 06.

[0077] Thus, on the one hand, the volume of the water treatment device 5 is increased to increase the processing capacity of the water treatment device 5, and on the other hand, it is convenient to connect the second sedimentation tank 512 with the sand washing assembly 22 and the screening device 1, and the water storage tank 52 with the conditioning device 4. In addition, part of the water treatment device 5 is located in the fifth vehicle 05, and the other part of the water treatment device 5 is located in the sixth vehicle 06, which improves the mobility of the vehicle-mounted slag treatment device of the embodiment of the present invention.

[0078] The following describes a method for treating slag according to an embodiment of the present invention.

[0079] The slag processing method of the embodiment of the present invention is based on the slag processing system of any of the above embodiments, and the slag processing method comprises the following steps:

[0080] The first vehicle 01, the second vehicle 02, the third vehicle 03, the fourth vehicle 04 and the fifth vehicle 05 are moved to a set area. Specifically, the first vehicle 01, the second vehicle 02, the third vehicle 03, the fourth vehicle 04 and the fifth vehicle 05 can be moved to the set area along a preset road surface, and the set area can be located near a construction site where slag is generated.

[0081] Therefore, the debris produced at the construction site can be directly transported to the vehicle-mounted debris processing system of the embodiment of the present invention, thereby reducing the transportation cost of the debris.

[0082] The screening device 1, the sand washing device 2, the conditioning device 4, the dehydration device and the water treatment device 5 are connected in sequence, and the conditioning device 4 and the water treatment device 5 are connected.

[0083] Specifically, the screening device 1 is connected to the sand washing device 2, the sand washing device 2 is connected to the conditioning device 4, the conditioning device 4 is connected to the dehydration device and the water treatment device 5, and the dehydration device is connected to the water treatment device 5 in a set area.

[0084] Therefore, the screening device 1, sand washing device 2, conditioning device 4, dewatering device and water treatment device 5 of the embodiment of the present invention are detachably connected. When processing slag, the screening device 1, sand washing device 2, conditioning device 4, dewatering device and water treatment device 5 are connected. In the transportation state, the screening device 1, sand washing device 2, conditioning device 4, dewatering device and water treatment device 5 are disconnected for easy transportation.

[0085] The slag is transported to the screening device 1 to be processed.

[0086] Specifically, the screening device 1 screens the slag into crushed stone and mortar, the sand washing device 2 processes the mortar into sand and mud, the conditioning device 4 conditions the mud, and the filter press device 3 is suitable for filtering the mud into mud cake and filtrate. The filter press device 3 filters the mud into mud cake and filtrate.

[0087] Therefore, after the screening device 1, the sand washing device 2, the conditioning device 4, the dehydration device and the water treatment device 5 are connected, the slag is processed into crushed stone, sand and gravel and mud cake. The crushed stone and sand can be recycled at the construction site, and the mud cake is small in size and flat in appearance for easy transportation, thereby reducing the cost of transporting the slag.

[0088] In some embodiments, the method for treating slag in the embodiment of the present invention further includes the following steps: using the clean water produced by the water treatment device 5 as the water source for the screening device 1 and the sand washing device 2 .

[0089] Specifically, in the screening device 1, under the impact of the water flow, the water and the slag are mixed, and the soil, sand and gravel in the slag are mixed with water to form mortar. The screening device 1 separates the debris such as crushed stone and garbage in the slag that are not easy to form mortar from the mud. In the sand washing device 2, under the action of the water flow, the mud in the mortar is diluted by the water flow, thereby improving the fluidity of the mud and facilitating the separation of the mud from the sand and gravel.

[0090] Therefore, the water treatment device 5 recycles the mud, supernatant and other liquids generated in the vehicle-mounted slag treatment system of the embodiment of the present invention, thereby reducing the water consumption of the vehicle-mounted slag treatment system of the embodiment of the present invention when treating slag. On the one hand, it is convenient for the vehicle-mounted slag treatment system of the embodiment of the present invention to work in areas where water is inconvenient to obtain, and on the other hand, it reduces the operating cost of the vehicle-mounted slag treatment system of the embodiment of the present invention.
