Description

Technical Field

[0001] This utility model belongs to the technical field of sand-water separators, specifically relating to a sand-water separator that is easy to maintain. Background Technology

[0002] Sand-water separators are mechanical devices used to separate solid particles such as sand and silt from water in a mixture. They are widely used in sewage treatment, construction sites, sand quarries, and other fields. Their core principle is to achieve solid-liquid separation through gravity, spiral propulsion, or centrifugal action. Common types include spiral and centrifugal separators.

[0003] However, in actual use, sand particles easily adhere to the spiral blades of the sand separator. If not cleaned for a long time, it can lead to reduced material conveying efficiency or blockage. The existing spiral blades and drive motor are fixed structures. When cleaning is required, the connection between the spiral blades and drive motor must be disassembled first, and then the spiral blades must be disassembled, which is very troublesome. Now, a sand separator that is easy to maintain is provided to alleviate the above-mentioned problems. Summary of the Invention

[0004] This utility model achieves the purpose of convenient disassembly and installation of spiral blades by using a combination of a positioning rod, a mounting hole, a fixed bushing, and a mounting plate, which allows the positioning rod to be inserted into the mounting hole and one end of the fixed bushing to be inserted into the mounting plate through the mounting sleeve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sand-water separator that is easy to maintain includes a treatment tank and a drainage trough connected to the left side of the treatment tank. A sand settling port is connected to the bottom of the treatment tank, and a sand lifting pipe is connected to the bottom of the sand settling port. A motor is connected to the right side of the sand lifting pipe via a bracket. A connecting plate is installed on the inner wall of the sand lifting pipe. A rotating shaft is provided inside the sand lifting pipe. A support plate is sleeved on the outer side of the rotating shaft. Multiple positioning rods are connected to the periphery of the support plate on the side away from the motor. A fixing sleeve is sleeved on the outer side of the rotating shaft. A fixing plate is connected to one end of the fixing sleeve. An installation hole is opened in the fixing plate. A spiral blade is connected to the outer wall of the fixing sleeve. An installation plate is connected to the outer side wall of the bottom left end of the sand lifting pipe via fastening bolts. One end of the fixing sleeve is inserted into the installation plate via an installation sleeve.

[0007] Preferably, the end of the rotating shaft away from the motor has a slot, and the inner wall of the fixed bushing away from the fixed plate is connected to a locking block.

[0008] Preferably, one end of the rotating shaft passes through the connecting plate and is connected to the output end of the motor via a coupling. The rotating shaft and the connecting plate are rotatably connected by a bearing. The other end of the rotating shaft extends to the bottom left end of the sand lifting pipe. One end of the fixed bushing is inserted into the mounting sleeve via a bearing.

[0009] Preferably, a filter screen is provided inside the drainage trough, the top of the filter screen penetrates through the top of the drainage trough and is connected to a pull plate, the lower surface of the pull plate is in contact with the top of the drainage trough, and both ends of the pull plate are connected to the top of the drainage trough by fixing bolts.

[0010] Preferably, the top of the processing box is connected to a feed pipe, the right side of the processing box is connected to an input pipe, the outside of the sand lifting pipe is connected to a sand outlet, and a collection box is provided at the bottom of the sand outlet.

[0012] Compared with the prior art, the gain effect of this utility model is as follows:

[0013] This utility model uses multiple positioning rods that are inserted into corresponding mounting holes, and one end of the fixed bushing is rotatably inserted into the mounting plate through the mounting sleeve. When a lot of sand and gravel adheres to the spiral blades, affecting the conveying efficiency or causing blockage, the fastening bolts are rotated to disconnect the sand lifting pipe and the mounting plate, and the mounting plate is pulled out. The mounting plate then drives the mounting sleeve and the fixed bushing away from the sand lifting pipe. The disassembly process is simple, does not require removing the motor, and is convenient for cleaning the spiral blades. Attached Figure Description

[0032] Working principle: In use, sand and water are first injected into the feed pipe 2, and coagulant is poured in through the input pipe 26. After sedimentation at the bottom of the treatment tank 1, water flows out from the drainage trough 22, and sand and gravel sink into the settling port 3 and enter the sand lifting pipe 4. The motor 8 is started to drive the rotating shaft 9, the fixed bushing 15 and the spiral blade 16 to rotate. Under the action of the spiral blade 16, the sand and gravel in the sand lifting pipe 4 are driven to rise. Thus, under the action of the sand outlet 5, the rising sand and gravel enter the collection box 6, thereby achieving the separation of sand and water. When a lot of sand and gravel adheres to the spiral blade 16, affecting the conveying efficiency or causing blockage, the fastening bolt 21 is rotated to disconnect the sand lifting pipe 4 and the mounting plate 18, and the mounting plate 18 is pulled out. The mounting plate 18 drives the mounting sleeve 19 and the fixed bushing 15 away from the sand lifting pipe 4. The disassembly process is simple, without the need to remove the motor 8, and it is easy to clean the spiral blade 16.
