Description

Technical Field

[0001] This utility model relates to the technical field of construction sludge treatment equipment, and in particular to a belt filter press for deep dewatering of construction sludge. Background Technology

[0002] During construction, a large amount of construction sludge containing moisture is generated. If discharged directly, it will not only cause environmental pollution but also waste resources. Therefore, construction sludge needs to be dewatered for subsequent transportation, storage or reuse. Belt filter press is one of the commonly used equipment in construction sludge dewatering. It separates the water from the sludge through the squeezing and conveying action of the filter cloth, thus achieving sludge dewatering.

[0003] However, the commonly used belt filter presses for dewatering construction sludge have certain drawbacks during use. These devices typically use a fixed housing to collect the dewatered sludge blocks. When too much sludge is collected in the housing, the heavy weight of the housing and the lack of a convenient moving mechanism make it difficult for workers to move the housing for cleaning. In this case, the machine needs to be stopped to handle the excess sludge. This not only leads to low machine efficiency and affects the overall progress of sludge treatment, but also requires more labor costs for housing cleaning and sludge transfer, bringing unnecessary economic burden to enterprises.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Because commonly used construction sludge dewatering equipment on the market usually uses a box to collect sludge, when too much sludge is collected in the box, the staff cannot move the box, which requires the staff to stop the machine to deal with the excessive sludge, resulting in low machine efficiency and increased labor costs. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the commonly used construction sludge dewatering equipment usually uses a box to collect sludge. When too much sludge is collected in the box, the staff cannot move the box, which requires the staff to stop the machine to deal with the excess sludge. This results in low machine efficiency and increased labor costs. To address this, we propose a belt filter press for deep dewatering of construction sludge.

[0006] To achieve the above objectives, this application adopts the following technical solution: a belt filter press for deep dewatering of construction sludge, comprising a frame, a feeding hopper fixedly connected to the surface of the frame, two rotating rods rotatably connected to the surface of the frame, filter cloth rotatably connected to the arc surfaces of the two rotating rods, a fixing block fixedly connected to the surface of the frame, a motor fixedly connected to the surface of the fixing block, the output end of the motor fixedly connected to the rotating rods, a vacuum device fixedly connected to the surface of the fixing block, a vacuum tube fixedly connected to the surface of the vacuum device, a suction tank fixedly connected to one end of the vacuum tube, a suction plate fixedly connected to the arc surface of the suction tank, the surface of the suction plate slidably connected to the surface of the filter cloth, two U-shaped plates fixedly connected to the surface of the frame, a collection cart slidably connected to the inner surfaces of the two U-shaped plates, a sliding rod slidably inserted into the surface of the U-shaped plates, an mounting block fixedly connected to one end of the sliding rod, and two fixing grooves formed on the surface of the collection cart.

[0007] Preferably, the arc surface of the slide rod is fitted with a spring, and the two ends of the spring are fixedly connected to the mounting block and the U-shaped plate, respectively.

[0008] Preferably, an L-shaped plate is fixedly connected to the surface of each of the two U-shaped plates, and the size of the L-shaped plate is adapted to the size of the collection vehicle.

[0009] Preferably, baffles are fixedly connected to the surfaces of the two U-shaped plates, and two upright plates are fixedly connected to the surfaces of the baffles. The upright plates are fixedly connected to the U-shaped plates.

[0010] Preferably, scrapers are fixedly connected to the surfaces of the two U-shaped plates, and the size of the slide rod is adapted to the size of the fixing groove.

[0011] Preferably, a fixing frame is fixedly connected to the surface of the frame, and a flat plate is fixedly connected to the surface of the fixing frame.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This invention achieves the effect of collecting mud lumps, avoiding the situation where commonly used construction sludge dewatering equipment on the market typically uses a box to collect sludge. When too much sludge is collected in the box, the staff cannot move the box, causing the staff to have to stop the machine to deal with the excess sludge. This results in low machine efficiency and increased labor costs, thus improving the practicality of the device. Attached Figure Description

The upright plate 19 is fixedly connected to the U-shaped plate 11. Through the cooperation of the baffle 18 of the U-shaped plate 11 and the upright plate 19, mud can be effectively prevented from being thrown out of the collection vehicle 12. Scrapers 20 are fixedly connected to the surfaces of the two U-shaped plates 11. The size of the sliding rod 13 is adapted to the size of the fixed groove 15.

A fixed frame 21 is fixedly connected to the surface of the frame 1. A flat plate 22 is fixedly connected to the surface of the fixed frame 21. Through the cooperation of the fixed frame 21, the flat plate 22 and the filter cloth 4, the flat plate 22 can be used to flatten the mud on the surface of the filter cloth 4 during the rotation of the filter cloth 4 for easy filtration.

[0023] Working principle: When the staff needs to pull out the collection cart 12, the staff pulls the two mounting blocks 14, the mounting blocks 14 drive the sliding rod 13 to slide, the sliding rod 13 slides inside the U-shaped plate 11, at this time the spring 16 is in a stretched state, the sliding rod 13 is away from the inner wall of the fixing groove 15, at this time the staff can pull the handle of the collection cart 12 to pull the collection cart 12, the collection cart 12 slides on the inner surface of the U-shaped plate 11 and the surface of the L-shaped plate 17, thus completing the removal of the collection cart 12.
