Description

Technical Field

[0001] This application relates to the field of wastewater treatment equipment, and more specifically, to a sand-water separator and pollution control equipment. Background Technology

[0002] Environmental pollution refers to natural or man-made damage, the act of adding a substance to the environment beyond its self-purification capacity, resulting in harm. It is a phenomenon in which human factors alter the composition or state of the environment, causing a decline in environmental quality, thereby disrupting and damaging the ecosystem and normal production and living conditions of humans. Environmental pollution includes air pollution, water pollution, soil pollution, etc. Due to insufficient anticipation of the negative impacts of highly developed industry, a large amount of dust-laden gas is generated during factory production.

[0003] Water pollution is generally treated at sewage treatment plants. Sewage usually contains a large amount of sand and gravel, which needs to be separated from the water. Sand-water separators are generally used for this separation. For example, a sand-water separation device for sewage treatment disclosed in Chinese application number 202020163972.3 has sand and water falling directly into the machine body and being transported by a screw conveyor. When the sand and water fall into the machine body, the impact force is large, which can easily cause damage to the equipment. Summary of the Invention

[0004] To overcome the shortcomings of the existing system, this application provides a sand-water separator and pollution control equipment, which can solve the problem that the sand and water fall directly into the machine body and are transported by a screw conveyor. When the sand and water fall into the machine body, the impact force is large, which can easily cause damage to the equipment.

[0005] On one hand, embodiments of this application provide a sand-water separator, including a sand-water separator and a material buffer assembly.

[0006] A sand-water separator includes a body, a feed pipe at the top of the body, a solid-liquid storage tank at the bottom of the body, and a screw conveyor on one side of the solid-liquid storage tank, wherein the screw conveyor is inclined.

[0007] The material buffer assembly includes a conical buffer body located directly below the feed pipe and connected to the machine body, wherein the conical end of the conical buffer body and the bottom end of the feed pipe form a discharge space.

Detailed Implementation

[0025] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0026] Please see Figures 1-7 This application provides a sand-water separator, including a sand-water separator 10 and a material buffer assembly 20.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7The sand-water separator 10 includes a body 110, specifically, a frame is installed on the side of the body 110. A feed pipe 111 is provided at the top of the body 110, and a solid-liquid collection tank 120 is connected to the bottom of the body 110. A screw conveyor 130 is connected to one side of the solid-liquid collection tank 120, and the screw conveyor 130 is inclined. A support frame 150 supports the bottom of the screw conveyor 130. Sand and water are fed into the body 110 through the feed pipe 111 and then fall into the solid-liquid collection tank 120. The screw conveyor 130 then transports the sand and gravel. Because the screw conveyor 130 is inclined, a liquid level difference is formed between it and the solid-liquid collection tank 120, thus separating the sand and gravel. The water remains inside the solid-liquid collection tank 120. When the sand and gravel are being transported, the water carried by the sand and gravel will fall into the solid-liquid collection tank 120 through the gaps, thereby achieving sand-water separation.

[0028] In this embodiment, a hot air blower 140 is installed at the discharge port of the screw conveyor 130. The screw conveyor 130 includes a conveying cylinder 131, which is inclinedly connected to the solid-liquid storage tank 120. A motor 132 is installed on the side of the conveying cylinder 131 away from the solid-liquid storage tank 120. A spiral blade 133 is installed at the output end of the motor 132, and the spiral blade 133 is rotatably disposed inside the conveying cylinder 131. A discharge bin 170 is provided at the bottom of the end of the conveying cylinder 131 away from the solid-liquid storage tank 120. The hot air blower 140 is installed on the top wall of the conveying cylinder 131, and the air outlet of the hot air blower 140 is located directly above the discharge bin 170. When the motor 132 is started, the spiral blade 133 rotates, and the sand and gravel are conveyed by the spiral, thereby conveying the sand and gravel out of the water inside the solid-liquid holding tank 120. The water is still in the solid-liquid holding tank 120, and due to the liquid level difference, the conveyed sand and gravel can fall into the solid-liquid holding tank 120 through the gap between the spiral blade 133 and the conveying cylinder 131, thus achieving sand-water separation.

[0029] In the specific setup, a liquid outlet pipe 160 is provided on the side of the solid-liquid holding tank 120. Open the liquid outlet pipe 160 to drain the water from the solid-liquid holding tank 120.

[0030] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6The material buffer assembly 20 includes a conical buffer body 210, which is located directly below the feed pipe 111 and connected to the machine body 110. The conical end of the conical buffer body 210 and the bottom end of the feed pipe 111 form a discharge space 230. When sand and water enter the machine body 110 from the feed pipe 111, they first come into contact with the conical buffer body 210 and then fall into the machine body 110. The conical buffer body 210 provides a buffering effect when the sand and water fall into the machine body 110, thereby reducing the impact force of the falling sand and water and improving the service life of the equipment. Furthermore, the conical shape of the buffer body 210 increases the area over which the sand and water fall during buffering.

[0031] In this embodiment, the conical buffer body 210 is provided with buffer connectors 220 arranged in a circular array, and the other end of each buffer connector 220 is connected to the inner wall of the body 110. Each buffer connector 220 includes a first connecting post 221, and each first connecting post 221 is arranged in a circular array on the outer side of the conical buffer body 210. The other end of each first connecting post 221 is provided with a spring 223, and the other end of each spring 223 is connected to a second connecting post 222, which is fixedly connected to the inner wall of the body 110. The springs 223 provide the conical buffer body 210 with a certain elasticity, thereby improving the service life of the conical buffer body 210.

[0032] Please see Figures 1-7 This application also provides a pollution control device, including the sand-water separator described above.

[0033] Among them, the sand-water separator 10 is used to separate sand and water in the sewage, thereby completing one step of sewage treatment.

[0034] The working principle of this sand-water separator and pollution control equipment is as follows: When sand and water enter the machine body 110 from the feed pipe 111, they first come into contact with the conical buffer body 210 and then fall into the machine body 110. The conical buffer body 210 provides a buffering effect when the sand and water fall into the machine body 110, thereby reducing the impact force and extending the service life of the equipment. Furthermore, the conical shape of the buffer body 210 increases the area over which the sand and water fall during the buffering process.

[0035] In summary, this application, through the setting of the conical buffer body 210, provides a buffering and supporting effect when sand and water fall into the machine body 110, thereby reducing the impact force of the falling sand and water and thus improving the service life of the equipment. Furthermore, due to the conical setting of the conical buffer body 210, the area of ​​sand and water falling can be increased during buffering.

[0036] It should be noted that the specific model and specifications of motor 132 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0037] The power supply and principle of motor 132 are clear to those skilled in the art and will not be described in detail here.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
