Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a sewage treatment solid waste separation device. Background Art

[0002] Domestic sewage contains a large amount of organic matter and suspended solids. During the treatment of this type of sewage, these organic matter and suspended solids will be separated to form sludge. Belt-type sludge dewatering machine is a kind of equipment used for sludge dewatering, usually composed of filter belt, roller cylinder, filter belt tensioning system, filter belt deviation adjustment system, filter belt flushing system and filter belt drive system. The working principle of belt-type sludge dewatering machine is based on physical filtration and mechanical extrusion. It uses two filter belts running continuously up and down to sandwich the flocculated sludge in the middle, and repeatedly squeezes it through several squeezing rollers to achieve dehydration.

[0003] The patent document with announcement number CN118993484B discloses a sludge dehydration and drying device for river sludge used for land reclamation, the device includes a drying structure, the drying structure includes a drying box and a conveying assembly, the conveying assembly includes a conveyor belt 1 and a conveyor belt 2 arranged in the drying box, a forward and reverse motor 1, two drive rollers 1 and a conveyor belt 1 form an upper conveying device, a forward and reverse motor 2, two drive rollers 2 and a conveyor belt 2 form a lower conveying device, the conveyor belt 1 rotates counterclockwise, and the conveyor belt 2 rotates clockwise, so as to convey the sludge, the two drive rollers 2 are arranged one high and one low, the distance between the conveyor belt 1 and the conveyor belt 2 is smaller as the distance is farther from the discharge elbow, and the sludge is squeezed and dehydrated during the transportation by the lower conveying device and the upper conveying device.

[0004] When the above-mentioned sludge dewatering and drying device dewaters the sludge, the sludge will spread around under the pressure when it is squeezed by the upper and lower conveyor belts, and the sludge will overflow from the edge of the conveyor belt. At this time, in order to avoid the sludge from being squeezed out from the side of the conveyor belt, there is usually a gap between the edge of the sludge and the edge of the conveyor belt, which leads to a decrease in the utilization rate of the conveyor belt. Moreover, when the sludge is squeezed, the density of the sludge in the middle of the conveyor belt will be greater due to its poor fluidity after being squeezed, while the sludge at the edge of the conveyor belt has better fluidity and can diffuse outward when squeezed. The density of the sludge is smaller, resulting in poor dewatering effect of the sludge at the edge. Summary of the invention

[0005] In view of this, the present invention provides a sewage treatment solid waste separation device to solve the technical problems in the prior art that there is a gap between the edge of the sludge and the edge of the conveyor belt, resulting in a decrease in the utilization rate of the conveyor belt and poor dehydration effect at the edge of the sludge.

The axes of the two driving rollers 1 41 and the two driving rollers 2 42 are parallel, and the distance between the two driving rollers 2 42 is greater than the distance between the two driving rollers 1 41, so that the length of the conveyor belt 2 3 is greater than the length of the conveyor belt 2.

[0037] like Figure 1 and Figure 2 As shown, the driving motor 43 is arranged on the frame 1, and the driving motor 43 drives one of the driving rollers 2 42 to rotate. A bridge wheel 44 is rotatably connected to one side of the driving roller 2 42 on the frame 1. The driving roller 2 42 and the bridge wheel 44 are connected via gear transmission, and the bridge wheel 44 and the driving roller 1 41 are connected via belt transmission. In this way, the driving roller 1 41 and the driving roller 2 42 rotate in opposite directions, so that the conveying directions of the conveyor belt 1 2 and the conveyor belt 2 3 are opposite, so that the conveyor belt 1 2 and the conveyor belt 2 3 squeeze the sludge between the conveyor belt 1 2 and the conveyor belt 2 3.

The feed port 175 is arranged in a line, which is conducive to the sludge falling into the rubber frame 31 evenly, thereby facilitating the sludge to be evenly squeezed and facilitating improving the consistency of the moisture content of the mud cakes after dehydration in each rubber frame 31.

[0045] like Figure 2As shown, a plurality of squeezing blocks 22 are arranged at intervals on the inner surface of the conveyor belt 2, and the side of the squeezing block 22 away from the inner surface of the conveyor belt 2 is arc-shaped. A plurality of squeezing rollers 11 are rotatably mounted on the frame 1, and the squeezing rollers 11 are located inside the conveyor belt 2 and are evenly distributed between two driving rollers 41, and the axis of the squeezing roller 11 is parallel to the axis of the driving roller 41. Squeezing rings 111 that can abut against the squeezing blocks 22 are rotatably mounted on the squeezing rollers 11 and the driving rollers 41. The plurality of squeezing rings 111 intermittently squeeze the squeezing blocks 22, and then the rubber blocks 21 squeeze the sludge in the rubber frame 31, leaving time for the water after the sludge is squeezed to be discharged.
