Abstract
Description
Technical Field
[0001] This application relates to the field of sand-water separation technology, and in particular to a novel sand-water separator. Background Technology
[0002] At the company's production site, wastewater from coal mining and rainwater are systematically collected into the wastewater treatment system through a planned network of drainage ditches. The treated water resources are given a new purpose: some are used for on-site environmental protection, such as dust suppression spraying on factory roads and irrigation of green spaces, contributing to improving the environmental quality of the factory area; others are reserved for fire fighting, providing a critical water source in response to sudden fires. This recycling model, turning wastewater into valuable resources, not only effectively reduces the environmental pressure caused by wastewater discharge but also achieves efficient reuse of water resources, fully demonstrating the company's commitment to green development and resource conservation in its production and operations.
[0003] Current wastewater treatment practices primarily rely on the addition of polyaluminum chloride (PAC), polyacrylamide (PAM), and alkali for water purification. However, due to limitations in existing treatment processes, even after chemical treatment, a large amount of impurities and suspended solids remain in the effluent. These impurities, when introduced into on-site water-using equipment along with recycled water, easily cause pipe blockages and equipment wear, severely impacting equipment operational stability and lifespan. Frequent equipment failures not only significantly increase maintenance frequency but also lead to high repair costs, creating a dual dilemma of technical bottlenecks and economic burdens. Therefore, exploring efficient and economical solid-liquid separation technologies to completely remove impurities and solids from wastewater has become a key technical challenge for ensuring stable operation of on-site water-using equipment and reducing maintenance costs, urgently requiring in-depth research and technological breakthroughs from the industry. Summary of the Invention
[0004] This device provides a novel sand-water separator, the specific implementation of which is as follows:
[0005] A novel sand-water separator includes:
[0006] A water collection tank that opens upwards;
[0007] The inclined feeding screw has one end inserted into the bottom of the water collection tank and the other end connected to the drive assembly. Sand and water are put into the water collection tank, and the feeding screw rotates to transport the sand and gravel at the bottom of the water collection tank upward.
[0008] The water collection tank consists of an integrated butterfly box and an inclined tube. The feeding screw is rotatably connected to the inclined tube. The top of the inclined tube has a sand outlet facing downwards, and the upper part of the butterfly box has a liquid outlet. The separated water overflows from the liquid outlet.
[0009] Based on the above technical solution, the water collection tank consists of two parts. The first part is a butterfly-shaped tank with a preferred length of 4500mm and a width of 1200mm. The second part is an inclined pipe that serves as a feeding mechanism, with a preferred pitch angle of 25°.
[0010] Preferably, a filter screen is provided on the liquid outlet.
[0011] Preferably, the drive assembly consists of a reducer and a motor, with the output end of the motor connected to the feeding screw via the reducer.
[0012] Preferably, a feeding pipe is suspended above the butterfly box, and the opening of the feeding pipe corresponds vertically to the butterfly box.
[0013] Preferably, it also includes a mounting bracket, with the water collection tank mounted on top of the mounting bracket.
[0014] Preferably, the bottom of the butterfly box has a cleaning port.
[0015] Based on the above technical solution, the feeding structure composed of a reducer, motor and screw can transport sand and gravel upwards. During this process, water is left behind through gaps or fine holes all around the screw, thus achieving sand-water separation.
[0016] Preferably, a filter screen is installed at the liquid outlet via an installation cylinder;
[0017] The mounting cylinder includes a connecting pipe connected to the liquid outlet, and a lateral guide pipe is vertically intersected in the middle of the connecting pipe. The filter screen is slidably installed in the lateral guide pipe through a translation component, and both ends of the lateral guide pipe are open.
[0018] Preferably, the translation component is a frame structure with a pair of filters arranged side by side inside; the top of the translation component is provided with a limiting slider, and the top of the lateral guide tube is provided with a limiting groove along its length direction. The limiting slider is a T-shaped structure that is slidably connected to the limiting groove.
[0019] Preferably, the top of the limiting groove is provided with a waist-shaped opening, the top of the limiting slider is provided with a push plate that slides through the waist-shaped opening, and a locking key is provided between the two.
[0020] Based on the above technical solutions, the locking key is a conventional pin or push-button structure. When the push plate is pushed into place and the filter screen is replaced, closing the locking key can effectively prevent the filter screen from shifting laterally, thus improving the stability after replacement.
[0021] In summary, this application includes the following beneficial technical effects:
[0022] 1. In this utility model, by setting up a water collection tank and an inclined feeding screw, the sand and water in the water collection tank are separated by the rotation of the screw, and the sand and gravel are discharged through the top of the water collection tank. After the water body is left to stand, the clean water overflows and is discharged, which greatly reduces the turbidity of the sewage, reduces the damage to the drainage equipment caused by water quality problems, and also reduces personnel maintenance costs.
[0023] 2. This utility model has a simple structure. By installing a filter screen at the liquid outlet, the overflowing water is further filtered, thereby reducing the turbidity of the sewage again.
[0024] 3. By setting up a translation component and an installation cylinder, this utility model achieves quick replacement of the filter screen without affecting the filtration effect as much as possible. Attached Figure Description

Sand and water are put into the water collection tank 1, and the feeding screw 2 rotates to transport the sand and gravel at the bottom of the water collection tank 1 upward. The water collection tank 1 is installed above the mounting frame 4.
[0044] The water collection tank 1 is composed of an integrated butterfly box 104 and an inclined tube 105. The feeding screw 2 is rotatably connected to the inclined tube 105. The top of the inclined tube 105 is provided with a sand outlet 101 facing downwards. The upper part of the butterfly box 104 is provided with a liquid outlet 103.
