Description

Technical Field

[0001] This utility model relates to the field of quartz sand impurity removal technology, and in particular to a quartz sand impurity removal device. Background Technology

[0002] Quartz sand is a silicon dioxide crystal with high hardness, wear resistance and corrosion resistance. It is widely used in glass, ceramics, casting and water treatment. Its impurity removal process usually involves washing with water to remove surface mud and sand, then acid washing to dissolve metal oxide impurities, and finally magnetic separation to remove magnetic minerals. However, water stains are easily left on the surface of quartz sand after washing, requiring additional drying treatment. Traditional processes cannot achieve efficient screening at the same time, resulting in a mixture of large and small particles.

[0003] Chinese patent discloses a cleaning and impurity removal device for quartz sand preparation (authorization announcement number CN217797682U). This patented technology includes a cleaning tank, with multiple water tanks fixedly connected to its lower surface; a nozzle connected to the water tanks via a water pump, the nozzles being staggered in position; a conveying auger movably connected inside the cleaning tank; and a drying tank with an inclined plate fixedly connected inside, the bottom of which is equipped with a heating wire. This structure allows for the cleaning of quartz sand raw materials using a smaller water source through the staggered nozzles and water tanks, thus saving water resources.

[0004] However, this patent still has shortcomings. While it saves water resources during use, the quartz sand undergoes significant wear on the inner wall of the equipment during the washing and impurity removal process due to the conveying action. Furthermore, it cannot be screened after washing, resulting in a mixture of large and small quartz sand particles. Additionally, a large amount of water stains remain on the outer wall of the quartz sand, requiring additional drying equipment. This discontinuous impurity removal process increases the production time of quartz sand and affects subsequent magnetic separation and acid washing for further impurity removal. Therefore, those skilled in the art have provided a quartz sand impurity removal device to solve the problems mentioned in the background section. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a quartz sand impurity removal device, comprising a base, a spiral groove one, a spiral groove two, a spiral groove three, a hopper, a hot air blower, a water pump, and a transfer box. The base has a spiral groove one positioned above it, a spiral groove two sleeved on the outer side of the spiral groove one, and a spiral groove three sleeved on the outer side of the spiral groove two. Support rods arranged in a circular array and longitudinally penetrating the spiral grooves one, two, and three are provided at the upper end of the base. A hopper is positioned above the base, and a transfer box is positioned below the hopper. The lower end of the transfer box is equipped with… The system includes a guide frame with a discharge port at its lower end that slopes inward toward the inner side of the spiral groove. A hot air blower and a water pump are mounted on the upper end of the base. A spiral tube (first section) located above the lower half of the spiral groove's processing area is mounted on the output end of the hot air blower. An air outlet is mounted on the lower end of the spiral tube. A spiral tube (second section) located above the upper half of the spiral groove's processing area is mounted on the output end of the water pump. A nozzle is mounted on the lower end of the spiral tube (second section).

[0008] Furthermore, a baffle is provided at the upper opening of the spiral groove, and an assembly groove that fits onto the outside of the spiral tube is provided inside the guide frame.

[0009] Specifically, when the quartz sand raw material output through the discharge port falls into the upper part of the spiral channel one, the baffle prevents the quartz sand raw material from falling to the outside, and the assembly groove ensures that the spiral tube two and the guide frame do not interfere with each other.

[0010] Furthermore, a conveying pipe is provided at the lower end of the hopper, an inlet communicating with the conveying pipe is provided at the upper end of the transfer box, and an outlet communicating with the guide frame is provided at the lower end of the transfer box.

[0011] Specifically, the hopper transports the quartz sand raw material through the feed inlet to the transfer box via the conveying pipe, and discharges it through the discharge outlet, thus realizing the transfer of the quartz sand raw material.

[0012] Furthermore, a motor is provided at one end of the transfer box, and a rotating shaft is provided at the output end of the motor and rotatably installed inside the transfer box. Rotating plates arranged in a ring array are sleeved on the outer wall of the rotating shaft, and wear-resistant heads that slide and fit against the inner wall of the transfer box are provided on the outer wall of the rotating plates.

[0013] Specifically, during the transfer of quartz sand raw materials, the wear-resistant head increases the strength of the rotating plate during the friction process with the inner wall of the transfer box, thereby controlling the feed rate of the quartz sand raw materials.

[0014] Furthermore, a discharge groove one is provided on one side of the lower end of the spiral groove two, a discharge groove two is provided on one side of the lower end of the spiral groove three, and a discharge groove three is provided on one side of the lower end of the spiral groove three.

[0018] 2. Beneficial effects

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] This invention continuously outputs quartz sand raw material through a hopper. The output quartz sand raw material enters the interior of spiral groove one and slides downwards along the inner wall of spiral groove one. During this process, cleaning fluid continuously washes the quartz sand raw material inside spiral groove one. The screen inside spiral groove one intercepts large particles of quartz sand, while small particles of quartz sand and the cleaning dirt fall downwards and enter spiral groove two, which is connected to the outside of spiral groove one. The screen at the center of spiral groove two intercepts small particles of quartz sand raw material. The cleaning fluid passes through the screen one to wash the interior of spiral groove two. The cleaning liquid and dirt enter spiral groove three for output, realizing solid-liquid separation. After cleaning, a hot air blower delivers a drying hot airflow to dry the quartz sand raw material. The equipment is compact and occupies little space. Cleaning and drying are carried out continuously. Screening is achieved during the process to avoid mixing of large and small particles, which helps with subsequent impurity removal and processing. The equipment enables continuous cleaning production, reduces production time, and improves the efficiency of cleaning and impurity removal.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A hot air blower 25 and a water pump 28 are provided at the upper end of the base 1. A spiral tube 26 located above the lower half of the processing area of ​​the spiral groove 2 is provided at the output end of the hot air blower 25. An air outlet 27 is provided at the lower end of the spiral tube 26. A spiral tube 29 located above the upper half of the processing area of ​​the spiral groove 3 is provided at the output end of the water pump 28. A nozzle 30 is provided at the lower end of the spiral tube 29. A screen 8 is provided in the center section of the spiral groove 2, and a screen 9 is provided in the center section of the spiral groove 3.

[0037] A baffle 32 is provided at the upper opening of the spiral groove 2, and an assembly groove 23 is provided inside the guide frame 22 to fit the outside of the spiral tube 29.

[0038] The lower end of the hopper 14 is provided with a conveying pipe 15, the upper end of the transfer box 31 is provided with a feed inlet 16 connected to the conveying pipe 15, and the lower end of the transfer box 31 is provided with a discharge outlet 21 connected to the guide frame 22.

[0039] A motor 17 is provided at one end of the transfer box 31. A rotating shaft 18 is rotatably installed inside the transfer box 31 at the output end of the motor 17. A rotating plate 19 arranged in a ring array is sleeved on the outer wall of the rotating shaft 18. A wear-resistant head 20 is provided on the outer wall of the rotating plate 19 and slides against the inner wall of the transfer box 31.

[0040] A discharge trough 11 is provided on one side of the lower end of spiral groove 12, a discharge trough 22 is provided on one side of the lower end of spiral groove 23, and a discharge trough 33 is provided on one side of the lower end of spiral groove 34. The outlets of discharge trough 11, discharge trough 22 and discharge trough 33 are misaligned.

[0041] The inner walls of the spiral groove 1 2 are provided with guide plates 1 5 that are inclined towards the center; the inner walls of the spiral groove 2 3 are provided with guide plates 2 6 that are inclined towards the center; and the inner walls of the spiral groove 3 4 are provided with guide plates 3 7 that are inclined towards the center.

[0042] In this embodiment, the quartz sand impurity removal equipment, which integrates cleaning, screening, and drying functions, achieves efficient processing of the entire quartz sand process through the coordinated design of a multi-layer spiral groove structure and a dynamic feeding system. During operation, the quartz sand raw material is input through the hopper 14 and, through the rotating plate 19 and wear-resistant head 20 within the transfer box 31, is conveyed at a controllable rate through the discharge port 24 to the spiral groove 2. As the raw material slides down the inner wall of the spiral groove 2, the cleaning fluid drawn by the water pump 28 is conveyed through the spiral tube 29. The nozzle 30 at the lower end of the spiral tube 29 continuously sprays the cleaning fluid, performing an initial rinse on the quartz sand, and screening out large particles of impurities. Screen 18 intercepts and outputs along discharge trough 11. Small particles of quartz sand and wastewater pass through screen 18 into spiral trough 23. In spiral trough 23, screen 29 further separates small particles of quartz sand and wastewater. Wastewater carrying impurities enters spiral trough 34 and is discharged through discharge trough 33. Small particles of quartz sand are output through discharge trough 22, completing particle size classification. When the cleaned quartz sand continues to descend in spiral troughs 12 and 2, the hot air flow delivered by hot air blower 25 through spiral tube 26 is evenly blown through air outlet 27. With the guide plate design on the inner wall of the spiral trough, the quartz sand is in a thin-layer tumbling state, achieving rapid drying.

[0043] The equipment adopts a three-stage spiral channel with staggered screening. The nested spiral channel structure realizes the spatial overlap of the washing, screening and drying processes. The difference in screen aperture between spiral channel 1 2 and spiral channel 2 3 forms a double classification. Spiral channel 3 4 serves as an independent drainage channel to avoid solid-liquid mixing. The hot air drying and washing spray areas are staggered. The rotational inertia of the spiral channel extends the material processing path and improves energy efficiency. The inclined design of guide plate 1 5, guide plate 2 6 and guide plate 3 7 forces the material to converge towards the center, which not only prevents particles from sticking to the wall and ensuring screening efficiency.

[0044] This integrated washing, screening, and drying process eliminates intermediate steps in traditional processes, reducing production time. The spiral channel and guide structure force material to center itself, preventing direct friction between raw materials and the equipment sidewalls, thus reducing wear. The combination of hot air drying and spiral conveying eliminates the need for additional drying equipment. Dual-screen grading allows for independent output of large and small quartz sand particles, providing pure raw materials for subsequent magnetic separation and acid washing, increasing product added value. It overcomes the limitations of traditional quartz sand impurity removal processes, achieving efficient, low-consumption, and precise continuous production with a compact structure, significantly improving the quality and efficiency of quartz sand processing.
