[0002] The sand-water filter is also known as a sand-water separator, a spiral sand-water separator, a rotary filter, a spiral separator, a shafted sand-water separator, a shaftless sand-water separator, a spiral sand-water separator, etc.; the sand-water filter is an integrated device for separating and lifting organic sand in sewage, which can separate particles with a particle size ≥ 0.2 mm, has a high separation efficiency, adopts a shaftless spiral and has no water bearings in water, and has the characteristics of light weight, compact structure, reliable operation, convenient installation, etc., and is an ideal sand-water separation device.

[0003] The Chinese patent with the patent number CN202323322751.9 discloses a sand-water separator with an anti-blocking structure, which includes a separator main body. One side of the separator main body is fixedly connected with a sand discharge pipe. The bottom ends of the separator main body and the sand discharge pipe are fixedly connected with support legs. One side of the support legs is fixedly connected with a support frame. Casters are arranged inside the support frame. A filter screen plate is arranged inside the separator main body. A push rod shaft is movably installed inside the sand discharge pipe, and a sand pushing spiral blade is fixedly connected to the outside of the push rod shaft.

[0004] For the fracturing natural quartz sand water-sand separator described in the above patent, under the push of the feeding auger, the sand grains are lifted along the inclined bottom of the U-shaped groove, continue to be pushed for a certain distance after leaving the liquid surface, and are discharged into the sand bucket through the feeding pipe after the sand grains are fully dehydrated. Although the above method can realize the separation of quartz sand by the separator, when the sand-water mixture is input into the water tank from the top of one end of the separator, the particles with a larger specific gravity in the mixture, such as sand grains, will deposit at the bottom of the trough-shaped bottom. When discharging the separated water, the finer sand grains will still be carried out by the water pump. At the same time, after the quartz sand enters the sand collecting hopper, the accumulated quartz sand will still retain liquid, resulting in a reduction in the separation effect of the device on water and sand.

[0007] (II) Technical Solutions

[0008] The present utility model is realized through the following technical solutions: The present utility model provides a fracturing natural quartz sand water-sand separator, which includes a separation box.

Four self-locking universal wheels are installed at the four corners of the bottom end of the sand collecting hopper. A water pump is installed on the side wall of the separation box opposite to the extension pipe. The lower end of the water pump is fixed with a water tank. Two first clamping blocks are symmetrically arranged on the two side walls inside the water tank. A first-stage sieve plate is arranged above the first clamping blocks. Two second clamping blocks are symmetrically installed on the other two side walls inside the water tank, below the first clamping blocks. A second-stage sieve plate is fixed above the second clamping blocks.

[0009] Further, a wear-resistant lining is arranged on the inner side wall of the separation box, inside the feeding auger. The top end of the separation box is fixed with a sealing cover. One side of the top end of the sealing cover is equipped with a feeding hopper. Two limiting blocks are symmetrically installed on both sides of the top end inside the separation box.

Four support rods are symmetrically arranged at the four corners of the bottom end of the separation box. The bottom ends of the support rods are connected with anti-slip feet.

[0010] By adopting the above technical solutions, after the mixed liquid enters the separation box, particles with a larger specific gravity in the mixed liquid, such as sand grains, will deposit at the bottom of the separation box. Under the push of the feeding auger, the sand grains are lifted along the inclined extension pipe, continue to be pushed for a certain distance after leaving the liquid surface, and are discharged into the sand collecting hopper through the feeding pipe after the sand grains are fully dehydrated. The sealing cover realizes the sealing function of the separation box, facilitating the separation work inside the separation box.

[0011] Further, the sealing cover is connected to the separation box by a clamping groove, the feeding hopper is inserted into the sealing cover, and the limiting blocks are connected to the separation box by screws.

[0012] By adopting the above technical solutions, the design of the feeding hopper facilitates adding the water-sand mixed liquid to be separated into the separation box.

[0013] Further, the filter plate is connected to the limiting blocks by a clamping groove, the drain valve is connected to the separation box by a flange, the support rods are connected to the separation box by screws, and the anti-slip feet are connected to the support rods by screws.

[0014] By adopting the above technical solutions, the design of the limit clamping block facilitates the installation and disassembly of the filter plate, so as to facilitate the removal and inclination of the filter plate. The design of the filter plate can separate larger gravel, garbage, etc. in the water-sand mixture, avoiding the entry of gravel into the device and damaging the device. The design of the drain valve can empty the device when it is not working. The design of the support rod cooperating with the anti-slip support feet realizes the supporting effect on the separation box.

[0015] Furthermore, the extension pipe is connected to the separation box by screws, the motor is key-connected to the feeding auger, and the feeding auger is rotatably connected to the separation box.

[0016] By adopting the above technical solutions, the extension pipe realizes the fixed installation of the feeding auger, facilitating the discharge of quartz sand by the feeding auger. The motor drives the feeding auger to rotate, thereby realizing the pushing of the deposited quartz sand.

[0018] By adopting the above technical solutions, the sand collecting hopper realizes the storage and placement of the separated quartz sand. With the design of the ultra-fine water drainage plate, it can drain the stored quartz sand, ensuring the separation effect of the device on the two. With the design of the self-locking universal wheels, it is convenient to move the sand collecting hopper at any time.

[0019] Furthermore, the water pump is connected to the separation box by screws, the water inlet pipe of the water pump is inserted into the separation box, both the first block and the second block are connected to the water tank by screws, and the density of the secondary sieve plate is greater than that of the primary sieve plate.

[0020] By adopting the above technical solutions, when the liquid level height of the water in the separation box reaches the height of the water inlet pipe of the water pump, the water pump will pump out the separated water and discharge it into the water tank. With the design of the primary sieve plate and the secondary sieve plate, it can perform secondary and tertiary separation on the finer sand particles in the water, ensuring the separation effect of the device between quartz sand and water.

[0021] (III) Beneficial effects

[0022] The present utility model has the following beneficial effects compared with the prior art:

[0023] To solve the problem that in the existing fracturing natural quartz sand water-sand separator, under the push of the feeding auger, sand grains are lifted along the bottom of the inclined U-shaped groove, continue to be pushed for a certain distance after leaving the liquid surface, and are discharged into the sand bucket through the feeding pipe after the sand grains are fully dehydrated. Although the above method can achieve the separation effect of the separator on quartz sand, when the sand-water mixture is input into the water tank from the top of one end of the separator, heavier particles such as sand grains in the mixture will deposit at the bottom of the trough-shaped bottom. When discharging the separated water, finer sand grains will still be taken out by the water pump. At the same time, after the quartz sand enters the sand collecting hopper, the accumulated quartz sand will still retain liquid, resulting in a reduction in the separation effect of the device on water and sand. Through the design of the primary sieve plate and the secondary sieve plate, the present utility model can perform secondary and tertiary separation on the pumped water, avoiding the discharge of finer sand grains with the separated water. At the same time, when the quartz sand enters the sand collecting hopper, combined with the design of the ultra-fine water drainage plate, during the accumulation process of the quartz sand, a small amount of liquid in the quartz sand can be screened out, effectively ensuring the separation effect of the device on water and sand.

When the liquid level height of the water in the separation tank 3 reaches the height of the water inlet pipe of the water pump 15, the water pump 15 will pump out the separated water and discharge it into the water tank 17. With the design of the upper-stage sieve plate 12 and the lower-stage sieve plate 16, the finer sand grains in the water can be separated twice and three times, ensuring the separation effect of the device between the quartz sand and the water. The different densities of the upper-stage sieve plate 12 and the lower-stage sieve plate 16 can effectively improve the separation effect of the device on the finer sand grains in the water.

The bottom of the support rod 4 is connected with an anti-slip foot 5. After the mixed liquid enters the separation box 3, the particles with a larger specific gravity in the mixed liquid, such as sand grains, will settle at the bottom of the separation box 3. Under the push of the feeding auger 18, the sand grains are lifted along the inclined extension pipe 22, continue to be pushed for a certain distance after leaving the liquid surface, and are discharged into the sand collecting hopper 9 through the feeding pipe 20 after the sand grains are fully dehydrated. The sealing cover 1 realizes the sealing function of the separation box 3, facilitating the separation work inside the separation box 3. The sealing cover 1 is connected to the separation box 3 by a clamping groove. The feeding hopper 6 is inserted into the sealing cover 1.

The water-sand mixture to be separated is added into the separation box 3 from the feeding hopper 6. When the sand-water mixture is input into the water tank 17 from the top of one end of the separator, the particles with a larger specific gravity in the mixture, such as sand grains, will settle at the bottom of the separation box 3. Under the push of the feeding auger 18, the sand grains are lifted along the inclined extension pipe 22, continue to be pushed for a certain distance after leaving the liquid level, and are discharged into the sand collecting hopper 9 through the discharge pipe 20 after the sand grains are fully dehydrated. With the design of the ultra-fine water drain plate 11, it can drain the sand grains. When the liquid level height of the water separated from the sand reaches the height of the water inlet pipe of the water pump 15, the water pump 15 will pump out the separated water and discharge it into the water tank 17.
