Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment, and in particular to a solid-liquid separation device for sludge treatment vehicles. Background Technology

[0002] A sludge treatment vehicle is a special vehicle designed for sludge treatment. It integrates the functions of sludge collection, transportation and treatment, and can quickly reach the source of sludge generation, such as sewage treatment plants and industrial wastewater discharge points, to perform preliminary treatment on the sludge.

[0003] Sludge solid-liquid separation facilitates the separate treatment of solids and liquids. The solid portion can be further processed, such as incineration, landfill, or resource recycling, while the liquid portion can be discharged or reused after treatment to meet standards, realizing resource reuse and environmental protection. At the same time, it reduces the volume and weight of sludge, thereby reducing subsequent treatment costs and environmental pressure.

[0004] In existing technologies, sludge solid-liquid separation mostly relies on its own gravity settling to achieve solid-liquid separation. However, due to the lack of external acceleration force, the liquid settling speed is relatively slow, resulting in low sludge treatment efficiency. When the amount of sludge is large, it is very easy for them to accumulate and block the flow path, affecting the solid-liquid separation efficiency of sludge. Utility Model Content

[0028] Reference Figure 1-4 This utility model provides a solid-liquid separation device for sludge treatment vehicles, comprising:

[0029] The main unit 100 includes a separation box 101. Multiple feed pipes 102 are fixedly connected to the top surface of the separation box 101, and a discharge pipe 103 is fixedly connected to one side surface of the separation box 101. A valve is provided on the discharge pipe 103. The feed pipes 102 and the discharge pipe 103 are used to allow sludge to enter and liquid to be discharged.

[0030] The roller pressing unit 200 includes a screen plate 201, which is fixedly connected to the inner wall of the separation box 101. A groove 202 is provided on the top inner wall of the separation box 101. A screw 203 is rotatably connected to both inner walls of the groove 202. A support plate 204 is threadedly connected to the wall of the screw 203. A pressing rod 205 is rotatably connected to the support plate 204. A reciprocating motor 206 is fixedly connected to the separation box 101. The output end of the reciprocating motor 206 is fixedly connected to one end of the screw 203. A material control component 207 is provided inside the separation box 101. The sludge is screened by the screen plate 201, and the reciprocating motor 206 drives the screw 203 to rotate, causing the support plate 204 to drive the pressing rod 205 to roll on the screen plate 201, squeezing the sludge and enhancing the solid-liquid separation effect of the sludge.

[0031] The material control component 207 includes multiple supports 207a, which are fixedly connected to the inner wall of the separation box 101. Inclined plates 207b are slidably connected to each of the supports 207a. The inclined plates 207b are movably arranged in the corresponding feed pipes 102. Contact blocks 207c are fixedly connected to both sides of the support plate 204. By moving the inclined plates 207b back and forth with the support plate 204, the inclined plates 207b on both sides are lifted up respectively, thereby controlling the sludge feeding rate and achieving the material control function to prevent excessive sludge from accumulating and clogging.

[0032] Furthermore, the support plate 204 is slidably connected in the groove 202, and the rolling rod 205 is in contact with the screen plate 201. The groove 202 guides and restricts the translation of the support plate 204, while the rolling rod 205 is beneficial for the rolling operation of sludge.

[0033] Furthermore, baffles 208 are hinged to both sides of the separation box 101, and collection frames 209 are fixedly connected to both sides of the separation box 101. By opening the baffles 208, the crushed sludge can be easily removed and dropped into the collection frames 209 for centralized processing.

[0034] Furthermore, two clamping plates 210 are rotatably connected to the two sides of the separation box 101. Both clamping plates 210 are in contact with the corresponding baffles 208. By rotating the clamping plates 210, they are made to fit with the baffles 208, thus blocking the baffles 208 and preventing them from opening and closing on their own due to the impact of sludge.

[0035] Furthermore, a pump body 211 is fixedly connected to the separation box 101. The output end and input end of the pump body 211 both move through the separation box 101 and are respectively arranged vertically. The pump body 211 circulates and transports the sludge, which facilitates the secondary separation of sludge solids and liquids and improves the separation accuracy of sludge.

[0036] During use, the sludge is screened by the screen plate 201, while the reciprocating motor 206 drives the screw 203 to rotate, causing the support plate 204 to drive the rolling rod 205 to roll on the screen plate 201, squeezing the sludge and enhancing the solid-liquid separation effect. At the same time, the inclined plate 207b moves back and forth with the support plate 204, lifting the inclined plates 207b on both sides respectively, controlling the sludge feeding rate, achieving the material control function, and preventing excessive sludge from accumulating and clogging.

[0037] By opening the baffle 208, the crushed sludge can be easily removed and dropped into the collection frame 209 for centralized processing. The rotating clamp 210 fits against the baffle 208, blocking it and preventing it from opening and closing automatically due to the impact of the sludge. The pump body 211 circulates and transports the sludge, facilitating secondary solid-liquid separation and improving the separation accuracy of the sludge.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
