[0036] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , and Figure 7 The present disclosure provides a waste ballast treatment vehicle, which comprises a vehicle 7, a screen cleaning module 5, a crushing module 1, a stone washing and screening module 2 and a storage module 6.

[0037] It can be understood that the ballast on the driving line is separated from the discarded ballast after being screened by the screening module 5, and the discarded ballast is sequentially crushed by the crushing module 1 and washed and screened by the stone washing and screening module 2, and can be converted into clean sandstone of at least one particle size range and stored in the storage module 6, thereby realizing the recycling of discarded ballast while realizing the treatment of discarded ballast, avoiding the land resource occupation problem caused by the stacking and burying of discarded ballast, and avoiding the waste of stone resources, thereby effectively improving the treatment quality of discarded ballast and reducing the treatment cost of discarded ballast.

[0038] Among them, since the screening module 5 is connected with the vehicle 7, and the crushing module 1, the stone washing and screening module 2 and the storage module 6 are respectively arranged on the vehicle 7, the crushing module 1, the stone washing and screening module 2 and the storage module 6 can follow the screening module 5, thereby realizing the screening work while synchronously processing the discarded ballast, thereby saving the transportation cost of discarded ballast and improving the processing efficiency of discarded ballast.

[0039] It should be noted that the driving line of the vehicle 7 can be a road with ballast such as a highway or a railway, and the vehicle 7 advances under the traction of the screening module 5, and the screening module 5 digs out the ballast in the line and screens it. The ballast meeting the standard is discharged from the first discharge end of the screening module 5 and backfilled into the driving line, and the ballast not meeting the standard is discharged from the second discharge end of the screening module 5 as discarded ballast. Among them, the discarded ballast includes stones with more dirt and stones with a particle size range that is too small.

[0040] The specific type of the screening module 5 can be set according to actual needs, and is not limited.

[0041] The crushing module 1 is used for crushing the discarded ballast, so that the discarded ballast can be converted into sandstone of a required particle size range, and the specific type of the crushing module 1 can be set according to actual needs, and is not limited.

[0042] The stone washing and screening module 2 is used for washing and screening the crushed discarded ballast, and the specific type of the stone washing and screening module 2 can be set according to actual needs, and is not limited.

[0043] The storage module 6 is used for storing the discharge of the stone washing and screening module 2, and the specific type of the storage module 6 can be set according to actual needs, and is not limited.

[0044] The crushing module 1, the stone washing and screening module 2 and the storage module 6 are respectively modularly configured, which can facilitate the overall installation on the vehicle 7.

[0045] As Figure 2 , Figure 3 , Figure 6 andFigure 7 As shown, in some embodiments, the vehicle 7 comprises a first flatcar 71, a second flatcar 72 and at least one fifth flatcar 75, the first flatcar 71 is connected with the screen module 5, the crushing module 1 is arranged on the first flatcar 71, the second flatcar 72 is connected with an end of the first flatcar 71 away from the screen module 5, the stone washing and screening module 2 is arranged on the second flatcar 72, and the fifth flatcar 75 is connected with an end of the second flatcar 72 away from the first flatcar 71, and the storage module 6 is arranged on the fifth flatcar 75.

[0046] It can be understood that, since the first flatcar 71 is connected with the screen module 5, and the second flatcar 72 is connected with an end of the first flatcar 71 away from the screen module 5, and the fifth flatcar 75 is connected with an end of the second flatcar 72 away from the first flatcar 71, the crushing module 1 on the first flatcar 71, the stone washing and screening module 2 on the second flatcar 72 and the storage module 6 on the fifth flatcar 75 can follow the screen module 5, so that the abandoned track ballast can be processed synchronously while the screen work is realized, thereby saving the transportation cost of the abandoned track ballast, and improving the processing efficiency of the abandoned track ballast.

[0047] Among them, the crushing module 1 is carried by the first flatcar 71, the stone washing and screening module 2 is carried by the second flatcar 72, and the storage module 6 is carried by the fifth flatcar 75, so that the modules for processing the abandoned track ballast are dispersed on multiple flatcars, which not only facilitates the maintenance of each module, but also enables the vehicle 7 to adapt to curved lines, gradient lines and the like.

[0048] It should be noted that the specific types of the first flatcar 71, the second flatcar 72 and the fifth flatcar 75 can be set according to actual needs, and no limitation is made thereto, for example, the first flatcar 71, the second flatcar 72 and the fifth flatcar 75 can all be rail flatcars.

[0049] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, in some embodiments, the screening module 5 includes a screening device 51, the screening device 51 is connected with the first flat car 71, the feeding end of the screening device 51 is connected with the ballast on the running line, the first discharging end of the screening module 5 is towards the running line, the crushing module 1 includes a crushing device 11, the crushing device 11 is arranged on the first flat car 71, the feeding end of the crushing device 11 is connected with the second discharging end of the screening module 5, the stone washing and screening module 2 includes a stone washing device 21 and a screening device 22, the stone washing device 21 and the screening device 22 are arranged on the second flat car 72 respectively, the feeding end of the stone washing device 21 is connected with the discharging end of the crushing device 11, the feeding end of the screening device 22 is connected with the discharging end of the stone washing device 21, the storage module 6 includes a first storage bin 61 and a second storage bin 62, the first storage bin 61 and the second storage bin 62 are arranged on the fifth flat car 75 respectively, the feeding end of the first storage bin 61 is connected with the first discharging end of the screening device 22, the feeding end of the second storage bin 62 is connected with the second discharging end of the screening device 22.

[0050] It can be understood that the ballast on the running line is separated from the waste ballast after being screened by the screening device 51, the waste ballast is crushed by the crushing device 11, washed by the stone washing device 21 and screened by the screening device 22 in turn, and can be converted into clean sand and gravel with at least two particle size ranges and stored in the first storage bin 61 and the second storage bin 62 respectively, thereby realizing the recycling of the waste ballast while realizing the treatment of the waste ballast, avoiding the land resource occupation caused by the stacking and burying of the waste ballast, and avoiding the waste of stone resources, thereby effectively improving the treatment quality of the waste ballast and reducing the treatment cost of the waste ballast.

[0051] Among them, since the screening device 51 is connected with the first flat car 71, and the crushing device 11 is arranged on the first flat car 71, the stone washing device 21 and the screening device 22 are arranged on the second flat car 72 respectively, and the first storage bin 61 and the second storage bin 62 are arranged on the fifth flat car 75 respectively, the crushing device 11, the stone washing device 21, the screening device 22, the first storage bin 61 and the second storage bin 62 can follow the screening device 51, thereby realizing the screening work while synchronously processing the waste ballast, thereby saving the transportation cost of the waste ballast and improving the processing efficiency of the waste ballast.

[0052] It should be noted that the specific type of the screening device 51 can be set according to actual needs, which is not limited, for example, the screening module 5 can include a screening machine.

[0053] The specific type of the crushing device 11 can be set according to actual needs, which is not limited, for example, the crushing device 11 can be a vertical shaft impact crusher.

[0054] The feeding end of the vertical shaft impact crusher is located at the top thereof, and the discharging end of the vertical shaft impact crusher is located at the bottom thereof. The vertical shaft impact crusher has different modes according to different structures and functions, such as a center feeding mode, a waterfall feeding mode, a stone hitting stone mode, and a stone hitting iron mode. In the completely center feeding mode, the waste ballast enters the center rotor of the vertical shaft impact crusher, and the waste ballast is thrown out by the high-speed rotor. The thrown waste ballast rebounds on the material lining of the surrounding guard plate or the impact guard plate, and collides with the waste ballast thrown out of the center rotor again when falling. The waste ballast is broken by multiple collisions and friction in the crushing cavity, and the broken waste ballast is discharged under the action of gravity. In the waterfall feeding mode, the waste ballast is divided into two parts, including the center waste ballast and the surrounding waterfall waste ballast. The waste ballast thrown out by the center rotor collides with the surrounding waterfall waste ballast first, and then collides with the material lining of the surrounding guard plate or the impact guard plate. In the stone hitting iron mode, the waste ballast directly collides with the surrounding guard plate. In the stone hitting stone mode, the waste ballast in the crushing cavity is stacked in the shell to form a material lining at a natural rest angle, and the high-speed waste ballast collides with the material lining.

[0055] Since the crushing module occupies a small space, the electric control module in the waste ballast treatment vehicle can also be transported by the first flat car 71. The electric control module can include a power distribution cabinet, a controller, and other electrical facilities.

[0056] The specific type of the stone washing device 21 can be set according to actual needs, and no limitation is made thereto. For example, the stone washing device 21 can be a spiral stone washing machine.

[0057] The spiral stone washing machine is a device for separating mud and sand by stirring the broken waste ballast through a spiral device. The spiral stone washing machine is arranged obliquely, and the tail of the spiral is immersed in a sedimentation tank at the lower part of a water tank. The broken waste ballast enters the sedimentation tank from a feeding tank, and rolls and grinds each other under the action of the spiral blade to remove impurities on the surface of the waste ballast and to destroy the water vapor layer covering the waste ballast, so as to facilitate dehydration. The particles with a larger specific gravity sink to the bottom of the tank and are pushed upward by the spiral blade. Since the length of the water tank exceeds the horizontal line at the lower part, the excess water in the waste ballast can be removed in this process. The overflow water is discharged into a tail sand recovery machine through an overflow tank, and the waste ballast is discharged from the discharge port at the upper end of the water tank.

[0058] The specific type of the screening device 22 can be set according to actual needs, and no limitation is made thereto. For example, the screening device 22 can be a vibrating screen.

[0059] The vibration screen adopts a self-synchronization principle. The centrifugal force generated at each moment along the vibration direction is always superimposed, and the centrifugal force along the normal direction is always counteracted, so as to form a single exciting force along the vibration direction, so that the screen box makes a reciprocating linear motion. The vibration screen of the screening device 22 can be equipped with double-layer screen meshes to separate out stones in a first particle size range and stones in a second particle size range, and can also realize a dehydration function.

[0060] The specific types of the first storage bin 61 and the second storage bin 62 can be set according to actual needs, and are not limited. For example, the first storage bin 61 and the second storage bin 62 can both be box structures. The first storage bin 61 and the second storage bin 62 can be arranged on the same fifth flat car 75, or can be arranged on two fifth flat cars 75, respectively.

[0061] As shown in Figure 7 some embodiments, the crushing module 1 further includes a first conveying device 12 arranged on the first flat car 71 and the second flat car 72. The feeding end of the first conveying device 12 is arranged below the discharging end of the crushing device 11, and the discharging end of the first conveying device 12 is arranged above the feeding end of the stone washing device 21.

[0062] It can be understood that the crushed waste ballast is conveyed by the first conveying device 12 and then enters the stone washing device 21, so as to ensure the continuous performance of the crushing, cleaning, screening and other processes in the waste ballast treatment vehicle, and further ensure the efficient treatment of the waste ballast as a whole.

[0063] The first conveying device 12 can adapt to the height difference between the discharging end of the crushing device 11 and the feeding end of the stone washing device 21, and further ensures the stable conveying of the waste ballast from the crushing device 11 to the stone washing device 21.

[0064] It should be noted that the specific type of the first conveying device 12 can be set according to actual needs, and is not limited. For example, the first conveying device 12 can include a turning belt conveyor. One end of the turning belt conveyor is arranged on the first flat car 71, and the other end of the turning belt conveyor is arranged on the second flat car 72. The turning node structure of the turning belt conveyor can be the same as the hinge structure between the first flat car 71 and the second flat car 72, and the turning center axis of the turning belt conveyor coincides with the hinge center axis between the first flat car 71 and the second flat car 72. Thus, by using the free turning of the turning belt conveyor, the waste ballast can be conveyed while meeting the turning needs of the vehicle 7.

[0065] As shown in Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, in some embodiments, the waste ballast treatment vehicle further comprises a flocculation module 3 and a filter pressing module 4, the flocculation module 3 comprises a flocculation device 31, the liquid inlet ends of the flocculation device 31 are connected with the liquid outlet ends of the screening device 22 and the washing device 21 respectively, the first liquid outlet end of the flocculation device 31 is connected with the liquid inlet end of the washing device 21, the filter pressing module 4 comprises a filter pressing device 41, the filter pressing device 41 is arranged on the fourth flat car 74, the liquid inlet end of the filter pressing device 41 is connected with the second liquid outlet end of the flocculation device 31, the liquid outlet end of the filter pressing device 41 is connected with the liquid inlet end of the washing device 21, and the discharge end of the filter pressing device 41 discharges solid material, wherein the storage module 6 further comprises a third storage bin 63, the third storage bin 63 is arranged on the fifth flat car 75, and the feeding end of the third storage bin 63 is connected with the discharge end of the filter pressing device 41.

[0066] It can be understood that, after the waste ballast is cleaned, the waste liquid sequentially undergoes flocculation of the flocculation device 31 and filter pressing of the filter pressing device 41, so that solid-liquid separation can be realized, and the generated solid material can be stored in the third storage bin 63, thereby avoiding the occurrence of environmental protection problems while treating the waste ballast, and facilitating the reuse of the waste liquid, thereby further improving the treatment quality of the waste ballast and reducing the treatment cost of the waste ballast.

[0067] It should be noted that the flocculation device 31 is used for flocculating the waste liquid generated by the washing device 21 and the screening device 22, and the specific type of the flocculation device 31 can be set according to actual needs, and no limitation is made thereto, for example, the flocculation device 31 can comprise a flocculation tank 311 and a dosing device 312, the liquid inlet ends of the flocculation tank 311 are connected with the liquid outlet ends of the screening device 22 and the washing device 21 respectively, the first liquid outlet end of the flocculation tank 311 is connected with the liquid inlet end of the washing device 21, the second liquid outlet end of the flocculation tank 311 is connected with the liquid inlet end of the filter pressing device 41, and the medicine inlet end of the flocculation tank 311 is connected with the medicine outlet end of the dosing device 312.

[0068] Among them, the waste liquid in the screening device 22 and the washing device 21 is pumped into the flocculation tank 311, the flocculation liquid in the dosing device 312 is pumped into the flocculation tank 311, the flocculation liquid and the waste liquid are mixed to make the suspended particles in the waste liquid gather and accelerate precipitation, and the solid-liquid mixture separated by precipitation enters the filter pressing device 41 from the second liquid outlet end of the flocculation tank 311 for filter pressing, and the clean liquid separated by precipitation enters the washing device 21 from the first liquid outlet end of the flocculation tank 311 for recycling. Therefore, the solid-liquid separation efficiency and separation quality of the flocculation module 3 and the filter pressing module 4 are effectively improved, and the treatment cost of the waste ballast is reduced.

[0069] The flocculation tank 311 is used to contain the waste liquid of the cleaned waste track ballast and the flocculation liquid. The specific type of the flocculation tank 311 can be set according to actual needs, and no limitation is made thereto. For example, the flocculation tank 311 can be a closed tank structure. The first liquid outlet end of the flocculation tank 311 is located at the top, and the second liquid outlet end of the flocculation tank 311 is located at the bottom.

[0070] The dosing device 312 is used to deliver the flocculation liquid into the flocculation tank 311. The specific type of the dosing device 312 can be set according to actual needs, and no limitation is made thereto. For example, the dosing device 312 can include a liquid tank and a liquid pump. The liquid tank is filled with the flocculation liquid. The liquid outlet end of the liquid tank is connected to the liquid inlet end of the liquid pump. The liquid outlet end of the liquid pump is connected to the liquid inlet end of the flocculation tank 311. Under the action of the liquid pump, the flocculation liquid is delivered into the flocculation tank 311.

[0071] The flocculation module 3 further includes a liquid storage tank 32. The liquid storage tank 32 is arranged on the third flat car 73. The first liquid inlet end of the liquid storage tank 32 is connected to the first liquid outlet end of the flocculation device 31. The second liquid inlet end of the liquid storage tank 32 is connected to the liquid outlet end of the filter pressing device 41. The liquid outlet end of the liquid storage tank 32 is connected to the liquid inlet end of the stone washing device 21.

[0072] It can be understood that the clean liquid discharged from the first liquid outlet end of the flocculation device 31 and the clean liquid discharged from the liquid outlet end of the filter pressing device 41 are collected in the liquid storage tank 32, so as to be conveniently delivered to the stone washing device 21 for recycling. In this way, the recycling efficiency of the clean liquid is improved, and the efficient cleaning of the waste track ballast by the stone washing device 21 is ensured.

[0073] The specific type of the liquid storage tank 32 can be set according to actual needs, and no limitation is made thereto. For example, the liquid storage tank 32 is a closed tank structure. In addition to the first liquid inlet end, the second liquid inlet end and the liquid outlet end, the liquid storage tank 32 further includes a liquid supplement end. During the process of treating the waste track ballast, if the liquid level in the liquid storage tank 32 is insufficient, the nearby water source can be used for liquid supplement.

[0074] The filter pressing device 41 is used to separate the solid and liquid of the flocculated waste liquid. The specific type of the filter pressing device 41 can be set according to actual needs, and no limitation is made thereto. For example, the filter pressing device 41 can be a plate-and-frame filter press.

[0075] The plate-and-frame filter press includes filter plates, filter chambers, a hydraulic system, filter frames, a filter plate transmission system, an electrical system and the like. When the plate-and-frame filter press is working, the filter plates are pressed tightly by the hydraulic system. The solid-liquid mixture is pumped into the filter chambers and passes through the filter medium such as filter cloth. The solid stays on the filter cloth and gradually accumulates to form a filter cake. The filtrate passes through the filter cloth into the return pipe and returns to the stone washing device 21 for recycling. After the plate-and-frame pressure is released, the filter plates are opened. The filter cake falls under the action of gravity, and thus the solid-liquid separation is completed.

[0076] After flocculation by the flocculation device 31 and pressure filtration by the pressure filtration device 41, the clean liquid can be separated from the waste liquid, and the clean liquid is returned to the stone washing device 21 for recycling, thereby effectively reducing the processing cost of the waste ballast and reducing the environmental problems in the waste ballast processing process.

[0077] Since the dirt on the waste ballast is mainly sludge, and the clean liquid for cleaning the waste ballast is water, the products after solid-liquid separation are mud cake and clean water, respectively. The mud cake can be used for environmental landfill or other fields, and the mud cake discharged by the pressure filtration device 41 is stored in the third storage bin 63.

[0078] The specific type of the third storage bin 63 can be set according to actual needs, and no limitation is made thereto. For example, the third storage bin 63 can be a box structure, and the first storage bin 61, the second storage bin 62, and the third storage bin 63 can be arranged on the same fifth flat car 75 or can be arranged on two or three fifth flat cars 75, respectively.

[0079] As shown in Figure 1 and Figure 3 In some embodiments, the stone washing and screening module 2 further comprises a cyclone device 23 arranged on the second flat car 72. The liquid inlet end of the cyclone device 23 is connected to the liquid outlet end of the screening device 22 and the liquid outlet end of the stone washing device 21, respectively. The liquid outlet end of the cyclone device 23 is connected to the liquid inlet end of the flocculation device 31, and the discharge end of the cyclone device 23 is connected to the feeding end of the screening device 22.

[0080] It can be understood that the waste liquid screened in the screening device 22 and the waste liquid generated by cleaning the waste ballast in the stone washing device 21 are subjected to solid-liquid separation when passing through the cyclone device 23. The solid material returns to the first screening device 22 for further screening, and the liquid material enters the flocculation device 31 for flocculation to further separate the solid and liquid. Therefore, by arranging the cyclone device 23, not only the output of the sand and stone from the screening device 22 can be increased, but also the solid impurities in the waste liquid can be reduced, thereby improving the flocculation efficiency of the flocculation device 31 and the pressure filtration efficiency of the pressure filtration device 41.

[0081] It should be noted that the specific type of the cyclone device 23 can be set according to actual needs, and no limitation is made thereto. For example, the cyclone device 23 can be a cyclone.

[0082] As shown in Figure 1 and Figure 3As shown in the drawings, in some embodiments, the stone washing and screening module 2 further comprises a collecting tank 24, the collecting tank 24 is arranged on the second flat car 72, a first liquid inlet end of the collecting tank 24 is arranged below a liquid outlet end of the screening device 22, a second liquid inlet end of the collecting tank 24 is connected with a liquid outlet end of the stone washing device 21, and a liquid outlet end of the collecting tank 24 is connected with a liquid inlet end of the cyclone device 23.

[0083] It can be understood that the waste liquid screened in the screening device 22 and the waste liquid generated by washing the waste ballast in the stone washing device 21 are collected in the collecting tank 24, so as to be conveniently transported to the cyclone device 23, thereby ensuring efficient separation of the waste liquid in the cyclone device 23, and reducing environmental problems caused by splashing and spilling of the waste liquid.

[0084] It should be noted that the specific type of the collecting tank 24 can be arranged according to actual needs, and no limitation is made thereto. For example, the collecting tank 24 can be a bucket structure, the larger end of the collecting tank 24 is located at the upper side, and the smaller end is located at the lower side. The waste liquid in the collecting tank 24 is pumped into the cyclone.

[0085] As shown in the drawings, Figure 4 , Figure 5 and Figure 7 In some embodiments, the vehicle 7 further comprises a third flat car 73 and a fourth flat car 74, the third flat car 73 and the fourth flat car 74 are arranged between the second flat car 72 and the fifth flat car 75, the third flat car 73 is connected with an end of the second flat car 72 away from the first flat car 71, the flocculation device 31 is arranged on the third flat car 73, the fourth flat car 74 is connected with an end of the third flat car 73 away from the second flat car 72, the fifth flat car 75 is connected with an end of the fourth flat car 74 away from the third flat car 73, and the filter pressing device 41 is arranged on the fourth flat car 74.

[0086] It can be understood that, since the third flat car 73 is connected with an end of the second flat car 72 away from the first flat car 71, and the fourth flat car 74 is connected with an end of the third flat car 73 away from the second flat car 72, the flocculation device 31 located on the third flat car 73 and the filter pressing device 41 located on the fourth flat car 74 can follow the cleaning and screening module 5, thereby realizing the cleaning and screening work while synchronously processing the waste liquid of the washed waste ballast, avoiding the occurrence of environmental problems, reducing the processing cost of the waste ballast, and improving the processing efficiency of the waste ballast.

[0087] Among them, the flocculation device 31 is carried by the third flat car 73, and the filter pressing device 41 is carried by the fourth flat car 74, so that the modules for processing waste liquid are dispersed on multiple flat cars, which not only facilitates the maintenance of each module, but also enables the vehicle 7 to adapt to curved lines, gradient lines, etc.

[0088] It should be noted that the specific types of the third flat car 73 and the fourth flat car 74 can be set according to actual needs, and no limitation is made thereto. For example, the third flat car 73 and the fourth flat car 74 can both be rail flat cars, and the screen cleaning device 51, the first flat car 71, the second flat car 72, the third flat car 73, the fourth flat car 74, and the fifth flat car 75 are sequentially connected.

[0089] As shown in FIG. 1, in some embodiments, the stone washing and screening module 2 further comprises a second conveying device 25 and a third conveying device 26. The second conveying device 25 is arranged on the second flat car 72, the third flat car 73, the fourth flat car 74, and the fifth flat car 75. The feeding end of the second conveying device 25 is arranged below the first discharging end of the screening device 22, and the discharging end of the second conveying device 25 is arranged in the feeding end of the first storage bin 61. The third conveying device 26 is arranged on the second flat car 72, the third flat car 73, the fourth flat car 74, and the fifth flat car 75. The feeding end of the third conveying device 26 is arranged below the second discharging end of the screening device 22, and the discharging end of the third conveying device 26 is arranged in the feeding end of the second storage bin 62. Figure 7 It can be understood that the first discharging end of the screening device 22 discharges the stones in the first particle size range to the first storage bin 61 through the second conveying device 25, and the second discharging end of the first screening device 22 discharges the stones in the second particle size range to the second storage bin 62 through the third conveying device 26. In this way, the refined output of the stones is realized, the overall stone output quality is improved, and different use requirements are met.

[0090] It should be noted that the specific type of the second conveying device 25 can be set according to actual needs, and no limitation is made thereto. For example, the second conveying device 25 can comprise a turning belt conveyor. The turning belt conveyor comprises a plurality of support ends, and the plurality of support ends are arranged on the second flat car 72, the third flat car 73, the fourth flat car 74, and the fifth flat car 75. The turning belt conveyor comprises a plurality of turning nodes, and the structure of the turning nodes can be the same as the hinge structure between adjacent flat cars. The turning center axis of the turning belt conveyor coincides with the hinge center axis between the corresponding adjacent flat cars. In this way, the free turning of the turning belt conveyor can meet the turning needs of the vehicle 7 while conveying the discarded ballast.

[0091]

[0092] ​The specific type of the third conveying device 26 can be set according to actual needs and is not limited thereto. For example, the third conveying device 26 may include a steering belt conveyor. The steering belt conveyor includes multiple support ends, which are respectively set on the second flatbed 72, the third flatbed 73, the fourth flatbed 74, and the fifth flatbed 75. The steering belt conveyor includes multiple steering nodes, and the structure of the steering nodes can be the same as the hinge structure between adjacent flatbed trolleys. The steering center axis of the steering belt conveyor coincides with the hinge center axis between the corresponding adjacent flatbed trolleys. Thus, by utilizing the free steering of the steering belt conveyor, the turning requirements of vehicle 7 can be met while conveying waste ballast.

[0093] like Figure 7 As shown, in some embodiments, the filter press module 4 further includes a fourth conveying device 42, which is disposed on the fourth flatbed trolley 74 and the fifth flatbed trolley 75. The feed end of the fourth conveying device 42 is disposed below the discharge end of the filter press 41, and the discharge end of the fourth conveying device 42 is disposed inside the feed end of the third storage bin 63.

[0094] It is understandable that the discharge end of the filter press module 4 discharges solid material to the third storage bin 63 through the fourth conveying device 42, thereby achieving temporary storage of solid material and avoiding the random discharge of solid material from affecting the travel route.

[0095] It should be noted that the specific type of the fourth conveying device 42 can be set according to actual needs and is not limited thereto. For example, the fourth conveying device 42 may include a steering belt conveyor, with one end of the steering belt conveyor mounted on the fourth flatbed car 74 and the other end mounted on the fifth flatbed car 75. The steering node structure of the steering belt conveyor can be the same as the hinge structure between the fourth flatbed car 74 and the fifth flatbed car 75, and the steering center axis of the steering belt conveyor coincides with the hinge center axis between the fourth flatbed car 74 and the fifth flatbed car 75. Thus, by utilizing the free steering of the steering belt conveyor, the turning requirements of the vehicle 7 can be met while conveying waste ballast.

[0096] After the various modules of the waste ballast treatment vehicle are installed, the inlet end of the stone washing equipment 21 and the outlet end of the water storage tank, the outlet end of the filter press equipment 41 and the second inlet end of the storage tank 32, and the outlet end of the cyclone equipment 23 and the inlet end of the flocculation equipment 31 can be connected by hoses to adapt to road conditions such as turning of the vehicle 7.

[0097] Because the particle size range of waste ballast is small and the mud content is low, the waste ballast processing vehicle uses relatively few devices to process waste ballast and produce usable sand and gravel. It has a strong overall processing capacity and low processing cost.
