Method used

In the sand washing process, the sand source is generally processed from materials such as limestone, granite, basalt, gneiss, and these articles are put into the wheel type sand washing machine 1 for crushing after repeated crushing, and the wheel The sand washing machine 1 has a large processing capacity, high output, and is easy to install and operate during use. After being cleaned by the sand washing machine 1, the sand particles larger than the screen installed in the sand washing machine 1 will be removed by the sand washing machine. 1, it will drop onto the linear vibrating screen 5 with the rotation of the wheel bucket. At the same time, the sand particles smaller than the screen installed in the sand washing machine 1 will be brought to the cleaning tank 2 by the water flow for further cleaning. The tank is a mixture of mud and sand. The mud, sand and water mixture is pumped by the slurry pump 3 to the separator 7 f...

Abstract

The invention relates to a novel sand washer. The novel sand washer effectively solves the problems that the number of devices adopted in the traditional sand making process is too large, power is too high, cost is high, and fine sand runoff is severe. According to the technical scheme, the novel sand washer comprises a wheel type sand washer. The discharge side of the wheel type sand washer is fixedly communicated with a washing tank, one side of the washing tank is communicated with a slurry pump, a motor is fixed to the other end of the slurry pump, a linear vibrating screen is fixed to the portion above the washing tank, a vibrating motor is fixed to the upper end of the linear vibrating screen, the slurry pump is communicated with a separator arranged above the washing tank through a pipeline, the lower port of the separator is arranged above the linear vibrating screen, the separator is communicated with a return box through a downwards-reversed U-shaped pipe, and the lower port of the return box is arranged above the linear vibrating screen. The novel sand washer is ingenious in structure, the sand washer is combined with a dehydration type fine sand recoverer, the sand washing process is greatly simplified, and the fine sand utilization rate is increased.

Example Embodiment

[0009] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0010] by figure 1 Given that the present invention includes a wheel-type sand washer 1, the discharge side of the wheel-type sand washer 1 is fixedly connected with a cleaning tank 2, one side of the cleaning tank 2 is connected with a slurry pump 3, and a slurry pump 3 A motor 4 is fixed at one end, a linear vibrating screen 5 is fixed above the cleaning tank 2, and a vibrating motor 6 is fixed at the upper end of the linear vibrating screen 5. The slurry pump 3 is connected to a separator 7 placed above the cleaning tank 2 through a pipeline. The lower port of 7 is placed above the linear vibrating screen 5, the separator 7 is connected to a return box 9 through a U-shaped pipe 8 that is inverted downwards, and the lower port of the return box 9 is placed above the linear vibrating screen 5.
[0011] The material of the linear vibrating screen 5 is a polyurethane screen.
[0012] The inner wall of the separator 7 is covered with a polyurethane layer.
[0013] When the present invention is used,
[0014] In the sand washing process, the source of sand is generally processed from limestone, granite, basalt, gneiss and other materials. These items are crushed many times before being crushed in the wheel sand washing machine 1. The wheel sand washing The machine 1 has large processing capacity, high output, easy installation and easy operation during use. After being cleaned by the wheel sand washer 1, the sand particles larger than the screen installed in the sand washer 1 will be picked up by the wheel sand washer 1. , As the bucket rotates and falls onto the linear vibrating screen 5, at the same time, sand particles smaller than the screen installed in the sand washing machine 1 will be carried by the water flow to the cleaning tank 2 for another cleaning. The cleaning tank is The mixture of mud and sand is pumped by the slurry pump 3 to the separator 7 for separation. The sand that meets the specifications enters the linear vibrating screen 5 through the lower port of the separator, and the linear vibrating screen is excited by the vibrating motor 6. Under the action of force, the material is thrown up from the screen and moves in a straight line, and finally the clean and dry sand is output as a finished product.
[0015] The traditional sand making and washing process is crushed by a sand making machine, and then directly turned into a finished product after being cleaned by the sand washer 1, or after passing through the cleaning tank 2, and then processed by a separator 7, and the unqualified products are directly thrown away. This results in a waste of resources, and more equipment is used in the whole process, with high power, space occupation and high cost.
[0016] In the traditional wet processing technology of artificial sand, the spiral sand washing machine used in the washing and dewatering of artificial sand, the loss of fine sand in the artificial sand can hardly be controlled. By adopting the present invention, the loss of fine sand can be effectively reduced, and the amount of fine sand can be controlled within 5%-10%, which can well solve the problem of high fineness modulus of finished sand and partial stone powder content in the artificial aggregate processing system. Low puzzle.
[0017] The linear vibrating screen 5 adopts a polyurethane screen with a longer life than other types of screens, and it is not easy to block holes.
[0018] The separator 7 is lined with polyurethane, which improves the service life of the entire device and can smoothly complete the work of slurry concentration and liquid clarification.
[0019] The invention can recover up to 85% of the fine particulate material in the total discharge, and has unparalleled technical and economic advantages of other equipment.
[0020] The fine particles of the invention are fully recovered, the workload of the cleaning tank is reduced, and the cleaning cost of the cleaning tank is reduced.
[0021] The invention has an ingenious structure, combines a sand washing machine with a dewatering fine sand recovery machine, greatly simplifies the sand washing process and improves the utilization rate of the fine sand.
