Description

Technical Field

[0001] The utility model relates to the technical field of sand and gravel separation, in particular to a sand and gravel separation and screening device. Background Art

[0002] Sand and gravel refers to a loose mixture of sand particles and crushed stone. In daily life, some people also call sandstone sand and gravel. Before the sand and gravel materials are used, a separation device is needed to separate large and small sand and gravel before they can be used.

[0003] The existing separation device generally pours sand and gravel into a screening box and screens them through an internal filter screen. Only one filtering component can separate large sand and gravel from small sand and gravel, but the dust contained inside cannot be separated, resulting in a decrease in the quality of the separated sand and gravel, and reducing the working quality of the screening device. At the same time, the long-term use of the filter screen can easily cause dust to accumulate in the filter holes, resulting in a decrease in the screening efficiency of sand and gravel, and reducing the working efficiency of the screening device.

[0004] According to the publication number: CN220803459U, a sand and gravel separation and screening device is provided, which includes a screening box body, and the screening box body includes an inner shell body and an outer shell body. A feed port is arranged above the screening box body, two rolling rollers are arranged inside the feed port, a dragon blade is arranged inside the inner shell body, a sieve hole is arranged on the inner shell body, the inner shell body is located inside the outer shell body, the feed port passes through the outer shell body to connect the inner shell body, a discharge port 1 is arranged at one end of the inner shell body away from the feed port, a discharge port 2 is arranged at one end of the outer shell body close to the feed port, a conveyor belt is arranged inside the outer shell body below the inner shell body, and a support leg is arranged below the outer shell body. The utility model crushes the agglomerated sand and soil by rolling rollers, and turns the sand and gravel materials evenly by the dragon blades, so that the sand and gravel materials are screened more evenly and fully, thereby increasing the screening efficiency.

[0005] According to the screening device introduced above, only large sand and gravel can be separated from small sand and gravel through only one filtering component, and the sand and gravel contained inside cannot be separated, resulting in a decrease in the quality of the separated sand and gravel, which reduces the working quality of the screening device. At the same time, the long-term use of the filter net is prone to accumulation of dust in the filter holes, resulting in a decrease in the screening efficiency of sand and gravel, which reduces the working efficiency of the screening device. Therefore, we need to propose a sand and gravel separation and screening device. Utility Model Content

[0027] Pour the sand and gravel into the screening box 1 from the feed inlet of the screening box 1, start the driving mechanism 4 to drive the two groups of guide plates 5 to push the sand and gravel to move. The sand and gravel fall on the primary filter screen 8. The small sand and dust pass through the filter holes and fall on the micro filter screen 9. The dust passes through the filter holes on the micro filter screen 9 and falls to the bottom of the screening box 1 and is discharged through the discharge port. During cleaning, start the water supply component 7 to send water flow into the high-pressure nozzle 3, and start the moving component 2 to drive the high-pressure nozzle 3 to move and wash the filter holes on the surfaces of the micro filter screen 9 and the primary filter screen 8, avoiding dust accumulation, thereby improving the quality of the separated sand and gravel, improving the working quality of the screening device, improving the screening efficiency of the sand and gravel, and increasing the working efficiency of the screening device.

[0028] The moving component 2 includes an electric push rod 21. The electric push rod 21 is bolted to the outer side wall of the screening box 1. The piston end of the electric push rod 21 penetrates through the screening box 1 and is fixedly connected with a moving seat 22.

The outer surface of the rotating rod 42 is inserted and fixed into the inner cavity of the material guiding plate 5. The shape of the material guiding plate 5 is spiral. When the servo motor 41 is started, the two groups of rotating rods 42 are driven to rotate through the transmission component. The two groups of rotating rods 42 drive the material guiding plate 5 to rotate at the same time. Because the material guiding plate 5 is spiral, the rotating rod 42 and the material guiding plate 5 can be combined into an auger conveyor frame, and the rotation of the material guiding plate 5 can push the sand and gravel to move towards the discharge port 10.

[0032] The transmission component includes a driving pulley 43. The surface of the driving pulley 43 is fixedly connected to the output shaft of the servo motor 41. The driving pulley 43 is connected to a driven pulley 44 through a belt. The inner walls of the driving pulley 43 and the driven pulley 44 are respectively fixedly connected to one ends of the two groups of rotating rods 42. The servo motor 41 drives the driving pulley 43 to rotate. The driving pulley 43 drives the driven pulley 44 to rotate through the belt, so that the driving pulley 43 and the driven pulley 44 drive the two groups of rotating rods 42 to rotate at the same time.

[0033] The water supply component 7 includes a water tank 71. The water tank 71 is fixedly connected to the upper surface of the base 6.

There are two groups of telescopic hoses 74. The cooperation of the high-pressure water pump 72 and the high-pressure nozzle 3 can realize the flushing of the filter holes on the filter net.

[0034] A notch is formed on the surface of the water tank 71. A glass plate 13 is embedded in the inner cavity of the notch of the water tank 71. The glass plate 13 is transparent. Through the setting of the glass plate 13, the staff can observe the water level height in the water tank 71 outside the water tank 71, avoiding the phenomenon that the water level in the water tank 71 is too low and the high-pressure water pump 72 cannot pump water.

[0035] During specific use: Pour the sand and gravel into the screening box 1 from the feeding port of the screening box 1. The sand and gravel fall on the primary filter screen 8. Start the servo motor 41 to drive the driving pulley 43 to rotate. The driving pulley 43 drives the guiding plate 5 to rotate through the rotating rod 42, and convey the sand and gravel on the primary filter screen 8. While the sand and gravel are moving, small particles and dust pass through the filter holes on the primary filter screen 8 and fall on the micro filter screen 9 at the bottom. At the same time, when the driving pulley 43 drives the driven pulley 44 to rotate through belt transmission, the guiding plate 5 drives the small particles and dust on the micro filter screen 9 to move. When moving, the dust passes through the filter holes on the micro filter screen 9 and falls into the bottom of the screening box 1, and is discharged through the discharge port. During cleaning, start the high-pressure water pump 72 to extract the water in the water tank 71 through the water suction pipe 73, and then the two groups of telescopic hoses 74 at the other end send the high-pressure water flow into the two groups of high-pressure nozzles 3. The high-pressure nozzles 3 spray the water flow on the surfaces of the primary filter screen 8 and the micro filter screen 9 to wash the dust. Start the electric push rod 21 to drive the moving seat 22 to move, so that the moving seat 22 drives the high-pressure nozzles 3 to move and wash the filter screen, thereby improving the quality of the separated sand and gravel, improving the working quality of the screening device, improving the screening efficiency of the sand and gravel, and increasing the working efficiency of the screening device.
