Abstract
Description
Technical Field
[0001] This utility model relates to the field of sand washing machine technology, specifically a sand washing machine for sand and gravel processing. Background Technology
[0002] During the mining process, sand and gravel often have a large amount of impurities such as mud and fine sand attached to their surface. If they are not effectively cleaned, these impurities will affect the bonding force between the sand and gravel and cement and other cementitious materials, resulting in a decrease in concrete strength and durability, which in turn poses a serious threat to the overall quality of the project.
[0003] Traditional sand and gravel washing equipment comes in various types, such as wheel bucket sand washers and spiral sand washers. However, these devices have many shortcomings in practical applications. Traditional material conveying methods mostly use simple funnels or conveyor belts for direct feeding, causing sand and gravel to fall in concentrated amounts and form localized accumulations within the washing tank, affecting the washing effect. On the other hand, the washing method is relatively simple, mainly relying on the flushing of water and the agitation of mechanical parts. This method has limited effectiveness in cleaning stubborn mud adhering to the surface of sand and gravel, as well as fine sand mixed within the sand and gravel. Utility Model Content

Two second springs 16 are fixedly connected to the upper surface of the support plate 15, and inclined cleaning plates 4 are fixedly connected to the upper surfaces of the two second springs 16.
[0034] The front end of the inclined cleaning plate 4 extends into the inner wall of the rectangular groove 3, and a baffle plate 12 is fixedly connected to the lower surface of the inclined cleaning plate 4. Two first springs 10 are fixedly connected to the lower surface of the inclined cleaning plate 4.
[0035] Among them, the two first springs 10 are fixedly connected to the inner wall of the rectangular groove 3, and the two rectangular grooves 3 and the two second springs 16 are all provided with auxiliary rods. The telescopic ends of the four auxiliary rods are fixedly connected to the upper surface of the inclined cleaning plate 4.
[0036] Among them, the two auxiliary rods located on the rear side are fixedly connected to the support plate 15, and the two auxiliary rods located on the front side are fixedly connected to the inner wall of the rectangular groove 3.
[0037] Furthermore, an installation groove 11 is provided on the front side of the upper surface of the inclined cleaning plate 4. The installation groove 11 penetrates the lower surface of the inclined cleaning plate 4, and a filter screen 18 is fixedly installed on the inner wall of the installation groove 11.
[0038] Four vibration motors 14 are fixedly installed on the lower surface of the inclined cleaning plate 4.
[0039] Furthermore, the cleaning assembly also includes multiple water supply pipes 6, all of which are fixedly connected to the upper surface of the cleaning tank 1;
[0040] Among them, the upper surface of multiple water pipes 6 is fixedly connected with two connectors 5 that communicate with their interiors, and the multiple connectors 5 are used to connect with external water pipes.
[0041] Furthermore, the lower ends of multiple water supply pipes 6 all penetrate into the interior of the cleaning tank 1, and multiple high-pressure nozzles 17 are fixedly installed at the lower ends of multiple water supply pipes 6.
[0042] Among them, the high-pressure nozzles 17 located at the front are vertically arranged, while the other high-pressure nozzles 17 are tilted backward.
[0043] Furthermore, the material conveying assembly includes a material conveying box 7, which is fixedly connected to the upper surface of the cleaning box 1. The material conveying box 7 communicates with the interior of the cleaning box 1, and a servo motor 8 is fixedly installed on the left side of the material conveying box 7.
[0044] Furthermore, the output end of the servo motor 8 is fixedly connected to a connecting shaft 19. The right end of the connecting shaft 19 rotates through into the interior of the feeding box 7 and is rotatably connected to the inner wall of the feeding box 7. The front and rear surfaces of the connecting shaft 19 are fixedly connected to a feeding plate 20.
[0045] Furthermore, a water outlet pipe 9 communicating with the interior is fixedly connected to the left side of the cleaning tank 1. A switch valve is installed on the water outlet pipe 9. An inclined plate 13 is fixedly connected to the front inner wall of the cleaning tank 1. The rear end of the inclined plate 13 is fixedly connected to the bottom of the cleaning tank 1.
[0046] Furthermore, when using this sand washing machine for sand and gravel processing, first connect the external water pipe to multiple connectors 5. In the initial state, the two unloading plates 20 are in a vertical state, and in the working state, they swing back and forth.
[0047] When cleaning sand and gravel, four vibrating motors 14, multiple high-pressure nozzles 17, and servo motors 8 are first started, and then the sand and gravel are put into the inside of the conveying box 7.
[0048] The output of the servo motor 8 drives the connecting shaft 19 to rotate, causing the front and rear unloading plates 20 to swing in a fan shape, which can break up the sand and gravel in the block, while slowing down the falling speed of the sand and gravel, and spreading the sand and gravel evenly on the inclined cleaning plate 4 to avoid the accumulation of feed. The four vibration motors 14 start synchronously, and through the elastic support of the first spring 10 and the second spring 16, the inclined cleaning plate 4 vibrates at high frequency. Under the action of vibration, the sand and gravel move forward along the inclined direction, and at the same time, they rub against each other to remove the surface dirt.
[0049] Multiple high-pressure nozzles 17 spray water to form a high-pressure water curtain, which washes away the sand and gravel, dispersing the mixed mud and fine sand. At the same time, the water flow pushes the sand and gravel towards the front of the washing tank 1. When the sewage and sand and gravel pass through the filter screen 18, the sand and gravel will pass through the filter screen 18, while the sewage carrying the mud will fall onto the inclined plate 13 and be discharged through the left-side water outlet pipe 9. It can be connected to the sedimentation tank for circulation treatment.
[0050] When the sand and gravel move to the front end of the inclined cleaning plate 4, they fall into the subsequent treatment area under the action of vibration and water flow, completing the cleaning process; the cooperation of the spring and the auxiliary rod buffers the vibration impact force, avoids damage to the cleaning plate due to rigid vibration, and at the same time ensures the stability of the tilt angle and optimizes the movement trajectory of the sand and gravel.
[0051] The device controls the oscillation frequency of the unloading plate 20 via the servo motor 8, which can adjust the sand and gravel feeding speed to meet different processing volume requirements. The multi-angle setting of the high-pressure nozzle 17 ensures thorough cleaning without dead angles. The synergistic effect of the vibration motor 14 and the inclined cleaning plate 4 improves the dispersion of sand and gravel and the cleaning efficiency. The device effectively separates impurities from sand and gravel, meeting the requirements of mining, construction and other industries for the cleanliness of sand and gravel. It has the advantages of high automation and uniform cleaning effect.
