Description

Technical Field

[0001] This utility model belongs to the field of quartz sand desliming technology, and particularly relates to a quartz sand desliming device. Background Technology

[0002] Quartz sand, also known as silica sand, is a common non-metallic mineral raw material with a wide range of applications. It is mainly used in the construction, glass manufacturing, ceramics, and foundry industries, which have significant demand for it. Natural quartz sand typically contains impurities such as mud, necessitating desliming to improve its bonding strength and meet process requirements. Current technology uses agitation to scrub and deslim the quartz sand, but this method suffers from insufficient shear force, long desliming time, and low efficiency. Therefore, a more efficient quartz sand desliming device is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide a quartz sand desliming device to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A quartz sand desliming device includes: a scrubbing tank and a stirring device and a jetting device disposed on the scrubbing tank;

[0006] The stirring device includes a motor, a stirring shaft, and a stirring part. The motor is located at the top of the scrubbing tank and its output shaft is coaxially connected downward to the stirring shaft. The stirring part is provided on the stirring shaft, and both the stirring shaft and the stirring part are located inside the scrubbing tank.

[0007] The jetting device circulates and extracts the liquid from the scrubbing tank and sprays it into the interior of the scrubbing tank.

[0008] As a further improvement of this utility model, the stirring part includes stirring blades, which are longitudinally extending spirals and connected to the stirring shaft;

[0009] The stirring blade is provided with multiple sets of fan blades, the top of the fan blades is connected to the stirring blade, and each set of fan blades is arranged radially along the stirring shaft.

[0011] As a further improvement of this utility model, a fixing ring is provided in the lower part of the interior of the scrubbing tank. The fixing ring is rotatably connected to the bottom of the stirring shaft, and the outer wall of the fixing ring is connected to the inner wall of the scrubbing tank by a connecting rod.

[0012] As a further improvement of this utility model, the jetting device includes a material extraction pipe, a pressure pump, and a jetting pipe;

[0013] One end of the extraction pipe is connected to the lower part of the scrubbing tank, and the other end is connected to the inlet of the pressurizing pump.

[0024] To better understand the purpose, structure, and function of this utility model, a clear and complete description of this utility model will be provided below in conjunction with the accompanying drawings.

[0025] like Figures 1-3 The quartz sand desliming device shown includes: a scrubbing tank 1 and a stirring device and a jetting device disposed on the scrubbing tank 1.

[0026] The scrubbing tank 1 is a vertical cylindrical body with a funnel-shaped bottom and a lid that can be fitted on the top. The upper part of the scrubbing tank 1 has a feed inlet 13 and a water inlet 14 for introducing quartz sand and water, respectively. A discharge pipe 11 is located at the center of the bottom of the scrubbing tank 1, and a water outlet pipe 12 is connected to the discharge pipe 11. A filter screen is installed inside the water outlet pipe 12. The water outlet pipe 12 and the discharge pipe 11 are detachably connected by a flange, and both the water outlet pipe 12 and the discharge pipe 11 are equipped with valves. After desludge removal, the valve on the water outlet pipe 12 is opened first, allowing wastewater to pass through the filter screen and be discharged. Then, the valve on the discharge pipe 11 is opened, allowing the clean quartz sand to be discharged under gravity, achieving efficient sand-water separation. Additionally, the bottom of the scrubbing tank 1 has multiple support legs 15. In this embodiment, three support legs 15 are evenly distributed along the circumference of the scrubbing tank 1, providing stable support by raising the scrubbing tank 1 to allow space for material discharge.

[0027] The stirring device includes a motor 2, a stirring shaft 3, and a stirring part. The motor 2 is located at the top of the scrubbing tank 1. Specifically, the motor 2 is mounted on the top of the tank cover via a motor mount. The output shaft of the motor 2 passes downward through the tank cover and is coaxially connected to the stirring shaft 3 via a coupling. The stirring part is provided on the stirring shaft 3, and both the stirring shaft 3 and the stirring part are located inside the scrubbing tank 1. Further, a fixing ring 6 is provided in the lower part of the interior of the scrubbing tank 1. The fixing ring 6 is rotatably connected to the bottom of the stirring shaft 3 via a bearing to fix the bottom of the stirring shaft 3 and reduce shaft end shaking. The outer wall of the fixing ring 6 is connected to the inner wall of the scrubbing tank 1 via connecting rods 7, which provide support for the fixing ring 6 and distribute the force. Three connecting rods 7 are provided.

[0028] In this embodiment, the stirring unit includes stirring blades 4, which are longitudinally extending spirals and connected to the stirring shaft 3. Multiple sets of fan blades 5 are provided on the stirring blades 4, with the tops of the fan blades 5 connected to the stirring blades 4. Each set of fan blades 5 is arranged radially along the stirring shaft 3 to enhance radial shear force. Furthermore, the width of the fan blades 5 gradually increases along the radial direction of the stirring shaft 3 to adapt to different flow velocity regions and optimize fluid shear efficiency. During rotation, a three-dimensional turbulent flow field with both longitudinal circulation and radial shearing is formed inside the tank, increasing the particle collision frequency and enhancing the desliming effect.

[0029] The jetting device circulates and extracts the liquid in the scrubbing tank 1 and sprays it into the interior of the scrubbing tank 1. Specifically, the jetting device includes a suction pipe 8, a pressurizing pump 9, and a jetting pipe 10; one end of the suction pipe 8 is connected to the lower part of the scrubbing tank 1, and the other end is connected to the inlet of the pressurizing pump 9. The outlet of the pressurizing pump 9 is connected to the jetting pipe 10. The free end of the jetting pipe 10 extends through the upper part of the side wall of the scrubbing tank 1 into the interior of the scrubbing tank 1; and the free end of the jetting pipe 10 is inclined downward at an angle of 15-30° to form a directional high-speed jet. In use, the pressurizing pump 9 extracts the mud-containing slurry, pressurizes it, and then sprays it back, which not only replenishes the turbulent energy in the tank but also washes away the sediment in dead corners, preventing secondary adhesion of fine mud.

[0030] This invention incorporates a stirring device and a jetting device, which work synergistically to enhance the mud-sand separation effect and improve the desliming efficiency of quartz sand.
