TECHNICAL FIELD
[0001] The utility model relates to the technical field of silica sand cleaning, especially to a silica sand pre-cleaning device. BACKGROUND
[0002] In the silica sand processing industry, silica sand is an important industrial raw material, widely used in construction, glass manufacturing, casting and many other fields. Before the subsequent processing of silica sand, it usually needs to be pre-cleaned to remove impurities such as soil and large particles, and its particle size also needs to be adjusted to meet the requirements of different production processes.
[0003] At present, the pre-cleaning process of silica sand generally involves multiple independent processing equipment and procedures, including conveying equipment, cleaning equipment, crushing equipment, screening equipment, and sedimentation separation equipment. These devices need to be purchased, installed and debugged separately, and need to occupy a large space. For example, the conveying equipment usually uses a conveyor belt or a simple screw conveyor to convey silica sand from the raw material pile to the cleaning equipment; the cleaning equipment uses water flow to wash the silica sand to remove the impurities on the surface; the crushing equipment crushes large pieces of silica sand or agglomerates into smaller particles; the screening equipment screens the silica sand according to different particle sizes; the sedimentation separation equipment processes the cleaning water containing impurities to separate the silica sand and soil.
[0004] In the prior art, the following problems exist:
[0005] 1) Since each process is completed by independent equipment, silica sand needs to be transferred between different equipment, which requires additional conveying equipment and complex connecting devices. In the material transfer process, silica sand is easy to spill and waste, not only wasting raw materials, but also increasing the difficulty and cost of cleaning work.

[0031] Please refer to the attached Figure 1 -Appendix Figure 4 As shown, the outer wall of the second pulley 308 is movably inserted into the interior of the support frame 2 and the crusher shell 4, and the functions are integrated: the rotating spray rod 302 integrates the material conveying (through the auger blade 303) and cleaning (through the water spray port 306) functions on one rod, which is movably inserted into the conveying cylinder 1, so that the material can be cleaned during the conveying process, improving the functionality and space utilization of the equipment, reducing the complexity and floor area of the equipment, and stable working: ensures the stable rotation of the rotating spray rod 302 in the conveying cylinder 1, avoids poor conveying and cleaning effect caused by unstable rotation, and at the same time can accurately adjust the position of the rotating spray rod 302 according to the size of the conveying cylinder 1 and the material conveying demand, improving the reliability and accuracy of the work.
[0032] The working principle is as follows: the motor 301 serves as a power source, and the output end of the motor 301 is fixedly connected to the rotating injection rod 302, and the outer wall of the rotating injection rod 302 is fixedly installed with the auger blade 303. When the motor 301 is started, the rotating injection rod 302 drives the auger blade 303 to rotate. Since the inner wall of the conveying cylinder 1 is in close contact with the auger blade 303, the rotation of the auger blade 303 can push the silica sand entering the conveying cylinder 1 to move along the conveying cylinder 1 in a certain direction, thereby realizing the conveying function of the silica sand. This auger conveying mode can ensure the continuous and stable transportation of the silica sand, and the rotation of the auger blade 303 can effectively prevent the silica sand from accumulating in the conveying cylinder 1, thereby ensuring the smoothness of the material conveying. The outer surface of the rotating injection rod 302 is provided with a water injection port 306. When the rotating injection rod 302 rotates, water can be supplied to the rotating injection rod 302 through an external water pipe or other water supply device. The water is sprayed out of the water injection port 306 to preliminarily wash the silica sand being conveyed in the conveying cylinder 1. While the silica sand is pushed by the auger blade 303, the water sprayed out of the water injection port 306 can wash away part of the impurities on the surface of the silica sand, thereby achieving the purpose of preliminary washing and improving the cleanliness of the silica sand. The first belt pulley 304 at one end of the rotating injection rod 302 drives the second belt pulley 308 to rotate through the transmission belt 307. When the second belt pulley 308 rotates, the first gear 309 fixedly connected to the outer wall of the second belt pulley 308 drives the second gear 310 engaged therewith to rotate. The outer surfaces of the first gear 309 and the second gear 310 are both fixedly connected to the stirring blade 311 through shafts. The two stirring blades 311 will rotate accordingly. Since the two stirring blades 311 are both movably inserted into the interior of the crusher shell 4 through shafts, when the silica sand is conveyed from the conveying cylinder 1 to the crusher shell 4, the rotating stirring blades 311 will perform a stirring operation on the silica sand to crush the silica sand or other impurities that may exist, so that the silica sand is more refined, which is helpful for subsequent washing and processing. The two ends of the second belt pulley 308 are both fixedly connected to the transmission rod 312 through shafts. The opposite sides of the two transmission rods 312 are fixedly connected to the screening plate 313 through shafts. The screening plate 313 cooperates with the discharge port 6 to move under the drive of the transmission rod 312 during the stirring and crushing process, so as to screen out the silica sand that has been crushed. The silica sand that does not meet the requirements will continue to be left in the crusher shell 4 for further crushing or other processing, so as to ensure that the silica sand finally discharged from the discharge port 6 meets certain particle size requirements. The outer wall of the conveying cylinder 1 is communicated with the crusher shell 4, and the bottom of the crusher shell 4 is fixedly connected to the yellow clay washing tank 5. When the silica sand and the washed wastewater flow into the yellow clay washing tank 5, the mud will be deposited at the bottom of the yellow clay washing tank 5 under the action of gravity and water flow due to the different densities of the silica sand and the mud, and the silica sand will be suspended in the water. The deposited mud can be discharged through the mud outlet 9 formed at the bottom of the yellow clay washing tank 5, and the silica sand can be discharged from the discharge port 6 of the yellow clay washing tank 5, thereby realizing the separation of the silica sand and the mud and further improving the purity of the silica sand.
