Description

Technical Field

[0001] The invention relates to the technical field of fine sand recovery machines, and in particular to a fine sand recovery machine. Background Art

[0002] The main function of the fine sand recovery machine is to clean, dehydrate and classify sand and gravel. It can effectively recover a large amount of fine sand lost by sand washing machines in the traditional sand making industry, thereby improving economic benefits and reducing the cost of tailings processing and the pollution and damage to the environment caused by the loss of fine sand.

[0003] At present, the existing fine sand recovery machine mainly has the following structural components: motor, vacuum high-pressure pump, sediment separator, TS dewatering screen, cleaning tank, return box. The vacuum high-pressure pump transmits power through the motor to transport the sand-water mixture to the sediment high-pressure separator. The tailings concentrated by centrifugal classification are provided to the dewatering screen through the sand settling nozzle. After dewatering by the dewatering screen, the tailings are effectively separated from the water. A small amount of tailings, mud, etc. are returned to the cleaning tank through the return box. When the liquid level in the cleaning tank is too high, it is discharged through the discharge port. Summary of the invention

[0004] In order to overcome the above disadvantages, the object of the present invention is to provide a fine sand recovery machine.

[0005] In order to achieve the above purpose, the technical solution adopted by the present invention includes a frame, a driving motor, a cyclone, a vibrating screen base, and a water tank, wherein: the water tank is installed in the vibrating screen base, and the upper surface of the water tank is flush with the upper surface of the vibrating screen base; the frame is installed above the vibrating screen base, and the driving motor is two symmetrically arranged parts, which are installed on the frame through the motor seat; a return box is also installed on the frame, and the cyclone is connected with the return box; the cyclone includes a feed port, a water outlet and a sand outlet, the feed port is connected with the water tank, and the water outlet is connected with the return box, and the waste water is discharged through the return box; the sand outlet is located above the frame; a slurry pump is also arranged between the feed port and the water tank, and the slurry pump is driven by the motor to suck the sand and water mixture in the water tank from the water tank into the feed port. The sand-water mixture in the water tank is sucked into the cyclone through the slurry pump. In the cyclone, due to the centrifugal force, the sand and water are separated. The separated sand is discharged through the sand outlet of the cyclone for recycling. The treated wastewater enters the return box through the water outlet of the cyclone and is finally discharged. The vibration function of the vibrating screen base helps to screen and recycle the sand and improve the processing efficiency of the equipment.

[0006] Furthermore, a plurality of support plates are arranged at intervals horizontally in the frame, and screens are laid on the support plates. The sand outlet can be directly opposite to the screen, and the screen is used to dehydrate the fine sand flowing out of the sand outlet again to obtain relatively drier fine sand.

[0007] Furthermore, it also includes an impurity filter box, which is connected to the water outlet. The impurity filter box is equipped with handrails and casters. The handrails and casters of the impurity filter box facilitate its movement, improve its convenience of use, and are suitable for more scenarios.

[0008] Furthermore, the impurity filter box includes a box body, the box body includes a box wall, a box bottom and a detachable box cover, and the box cover includes a water inlet, and the water inlet is provided with a plurality of filter holes. When wastewater enters the impurity filter box through the water inlet, they will first pass through the filter holes on the water inlet for preliminary filtration. Large impurities will be blocked outside the box cover by the filter holes, while liquid wastewater will continue to enter the box body.

[0009] Furthermore, a transparent observation window is provided on the box cover, and a drain port is provided on the box wall, which is connected to a ball valve, so that the operator can visually observe the situation inside the box, including the accumulation degree of impurities and the clarity of the filtered liquid, without opening the box cover.

[0010] Furthermore, the box body includes a first filter layer and a second filter layer, a bracket is symmetrically provided on the box wall, the first filter layer is placed on the bracket, and the drain port is provided below the second filter layer. The filtering accuracy of the second filter layer is usually higher than that of the first filter layer to ensure the purity of the liquid or material finally discharged. It is provided below the second filter layer to discharge the liquid or material after being filtered by the two layers. The drain port is connected to the ball valve to facilitate the operator to control the discharge of the liquid.

[0011] Furthermore, a receiving tray is placed on the first filter layer, and a handle is provided at the end of the receiving tray to facilitate operators to take the receiving tray out of the box body to clean and dispose of impurities.

[0012] The beneficial effects of the present invention are:

[0013] 1. Filter impurities through the impurity filtering water tank, so as to facilitate the screening of sand particles in the process of sand washing, so as to filter the fine sand. The filter box is divided into three layers. The first layer is the buffer layer, which buffers the sewage and has a beautiful appearance, and then it is convenient to scrape off the impurities on the filter net to prevent the filter net from being blocked; the second layer is the sewage sedimentation layer, which precipitates the sewage, and the clean water overflows and flows into the bottom drainage layer. By setting a water pump, it is convenient to extract the water in the fine sand, which helps to recover the fine sand; the third layer is the drainage layer, which drains the clean water and a small amount of impurities can be precipitated; through the fine sand recovery machine, it is convenient to recover the fine sand in the process of sand washing by the sand washing machine, avoiding the waste of fine sand, thereby achieving the purpose of saving resources. It is reasonably designed, easy to operate, meets social needs, and is worthy of promotion to sand washing machines.

[0014] 2. The fine sand recovery machine can filter out the large volume of garbage in the fine sand raw material, and make the remaining fine sand flow into the cleaning box through the filter box, so as to facilitate the filtering of large volume of garbage in the fine sand to improve the purity of the fine sand.

The sand-water mixture in the water tank 5 is sucked into the cyclone 3 through the slurry pump 6. In the cyclone 3, due to the centrifugal force, the sand and water are separated, and the separated sand is discharged through the sand outlet 33 of the cyclone 3 for recycling. The treated wastewater enters the return box 9 through the water outlet 32 ​​of the cyclone 3 and is finally discharged. The vibration function of the vibrating screen base 4 helps to screen and recycle the sand and improve the processing efficiency of the equipment.

[0023] In some embodiments, a plurality of support plates are arranged horizontally at intervals in the frame 1, and a screen 11 is laid on the support plates, and the sand outlet 33 can face the screen 11. The different apertures of the screen 11 can screen particles of different sizes, and the design of the sand outlet 33 facing the screen 11 is convenient for collecting and processing the screened materials, and the fine sand flowing out of the sand outlet 33 is dehydrated again by the screen 11 to obtain relatively drier fine sand.
