[0010] Preferably, the diameter of the collecting cylinder opening is larger than the diameter of the discharge port, the bottom of the collecting cylinder is provided with a metal filter screen, and the bottom of the cylinder is hollow, so that the water can be automatically drained when the quartz sand falls into the collecting cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This device removes impurities from quartz sand by using a sand washing machine and a secondary cleaning device, which can effectively improve the cleaning effect and ensure the quality of subsequent quartz sand processing. In addition, the sand washing machine and the secondary cleaning device are connected by a fixing buckle during use. After use, the device is easy to disassemble and can be directly moved. After the move, it can not only increase the working space in the production workshop, but also better store the machine and extend its service life.

[0013] This device is a secondary treatment for quartz sand. The secondary cleaning device does not require manual intervention. The conveyor belt is equipped with scrapers. When the conveyor belt is transporting the quartz sand that has been cleaned by the sand washing machine in the first stage, water is sprayed from the nozzles at the same time. The water flow will wash the quartz sand a second time. Finally, the quartz sand falls into the collection cylinder through the discharge buckle of the bottom plate. The quartz sand can avoid secondary pollution during the transfer process. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 - Figure 4 As shown, this utility model provides the following technical solution:

[0021] The system includes a sand washing machine 1, which transfers the cleaned quartz sand to a secondary cleaning device 22. The secondary cleaning device 2 is located at the discharge point of the sand washing machine 1. The secondary cleaning device 2 is connected to the sand washing machine 1 via a fixing buckle 3. The fixing buckle 3 is installed on the sand washing machine 1 and a fence on the side near the sand washing machine 1. A fixing limit block is provided on the fence on the side near the sand washing machine 1. The fixing buckle 3 has two connecting legs 301 and a fixing block 302. The connecting legs 301 are fixed to the fixing block 302. The opposite sides of the two connecting legs 301 are provided with connecting grooves 303. One connecting groove 303 is used in conjunction with the limiting block. The limiting block is fixed to the secondary cleaning device 2 and the sand washing machine 1.

[0022] The secondary cleaning device 2 includes a base plate 201, a enclosure 202, and a conveyor belt 203. The enclosure 202 is installed on both sides of the base plate 201 and on the side of the base plate 201 closest to the sand washing machine 1. The conveyor belt 203 is located above the base plate 201 and fixed to the enclosure 202. Several nozzles 4 are provided on the enclosure 202 on both sides of the base plate 201 closest to the sand washing machine 1, spraying towards the conveyor belt. Several evenly arranged scrapers 204 are provided on the surface of the conveyor belt 203. The height of the scrapers 204 is similar to the distance between the conveyor belt 203 and the base plate 201. The sides of the scrapers 204 are close to but not touching the inner side of the enclosure 202. The secondary cleaning device 2 is inclined downward along the conveying path. Two sets of support legs 6 are provided on both sides below the base plate 201. The support leg on the side closer to the sand washing machine 1 is higher than the support leg on the other side. Rollers 7 are provided below the support legs.

[0023] The nozzles on the side walls 202 of the base plate 201 are connected to water pipes, and the other side of the water pipes is connected to a booster pump. After the quartz sand is washed by the sand washing machine 1, it is transferred to the secondary cleaning device 22. The impurities on the surface of the quartz sand are relatively cleaned, and then the surface is cleaned again by the nozzles.

[0024] The bottom plate 201 is provided with a discharge port 205 at the end of the conveying path of the conveyor belt 203. A collection cylinder 5 is provided below the discharge port 205.
