Description

Technical Field

[0001] This utility model relates to the field of high-purity quartz sand drying technology, and in particular to a high-purity quartz sand drying device. Background Technology

[0002] Quartz sand is quartz particles produced by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Quartz sand is milky white or colorless and translucent. It is an important industrial mineral raw material, a non-hazardous chemical, and is widely used in glass, casting, ceramics and fireproof materials, ferrosilicon smelting, metallurgical solvents, metallurgy, construction, chemicals, plastics, rubber, abrasives and filter media industries. In the production process, quartz sand needs to be thoroughly mixed with water and then floated. After the floatation is completed, the quartz sand, which is rich in water, needs to be dried.

[0003] For example, utility model application number 202322538087.5 discloses a high-purity quartz sand drying device. The device uses a motor to drive a rotating shaft, which in turn drives a partition plate to rotate. Quartz sand is then added to the drying body through a feeding port, ensuring that quartz sand is evenly distributed between adjacent partition plates. A heating fan is started to transfer heat into the drying body. Then, a cylinder is started, which drives a rack to move back and forth. The rack drives a gear to rotate, thereby causing the support shaft, support block, and drying body to swing back and forth. This achieves the goal of separating a large amount of quartz sand into layers and achieving high drying efficiency.

[0004] The above-mentioned applications still have shortcomings:

[0005] This high-purity quartz sand drying device fails to separate the moisture from the high-purity quartz sand during the drying process. The water remains inside the drying unit and is difficult to remove, resulting in a high water content and reduced subsequent drying efficiency. Furthermore, the hot air does not come into uniform contact with the quartz stone, further reducing the drying efficiency.

[0006] To address these issues, a high-purity quartz sand drying device was designed. Utility Model Content

[0007] The main purpose of this invention is to provide a high-purity quartz sand drying device to solve the related technical problems mentioned in the background art.

[0008] The objective of this utility model can be achieved by adopting the following technical solution:

[0009] A high-purity quartz sand drying device includes an outer shell, a feed hopper installed at the top of the outer shell, a screening frame installed inside the outer shell, an isolation plate located in the middle of the outer shell, a fixed barrel installed at the bottom of the isolation plate, a screening screen installed inside the screening frame, a rotary motor installed on one side of the outer shell, a screen cylinder fixed to the output shaft of the rotary motor and located inside the fixed barrel, scrapers evenly arranged on the outer side of the screen cylinder, a fan installed on the other side of the outer shell, the output end of the fan fixedly connected to one end of the screen cylinder, a heating chamber installed on one side of the outer shell above the fan, a heating pipe fixed inside the heating chamber, a through pipe fixed to the input end of the fan, and the top end of the through pipe penetrating and extending into the interior of the heating chamber.

[0010] Preferably, an air inlet pipe is fixedly connected to one side and the lower position of the heating chamber, and the top end of the air inlet pipe extends to the top of the outer shell. A dehumidification pipe is evenly installed at the bottom of the air inlet pipe, and the bottom of the dehumidification pipe penetrates and extends into the interior of the outer shell. A guide block is provided inside the heating chamber, and a water filter membrane is provided on one side of the guide block.

[0011] Preferably, a vibration motor is installed at the bottom of the screening frame, a fixing plate is fixed to the outside of the screening frame, fixing rods are evenly installed at the bottom of the fixing plate, a spring is sleeved on the outside of the fixing rod, a support plate is fixed inside the outer shell and below the fixing plate, and the bottom of the fixing rod extends through and to the bottom of the support plate.

[0012] Preferably, the bottom of the fixed barrel is provided with a discharge pipe, and a valve is provided on the discharge pipe.

[0013] Preferably, an arc plate is provided in the middle of the screening frame, and guide plates are provided on both sides of the arc plate at an incline.

[0014] Preferably, a collection frame is slidably installed inside the heating chamber and below the flow guide block, and a handle is provided on one side of the collection frame.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model provides a high-purity quartz sand drying device. Through the coordinated use of a shell, feeding hopper, screening frame, screening screen, rotary motor, screen cylinder, fan, connecting pipe, fixed barrel, scraper, heating chamber, heating pipe and air inlet pipe, the heated air inside the heating chamber can be transported to the screen cylinder by the fan. The hot air is fully and evenly contacted with the quartz sand through the mesh of the screen cylinder, which increases the drying area of ​​the quartz sand and makes the drying efficiency higher, thereby improving the drying efficiency of the high-purity quartz sand drying device.

[0017] By using a combination of dehumidification pipes, guide blocks, filter membranes, isolation plates, fixing plates, fixing rods, springs, support plates, and a vibrating motor, after the quartz sand enters the screening frame, the vibrating motor is started to drive the screening frame. Under the elastic force of the springs, the screening frame shakes up and down, causing the quartz sand on the screening screen to shake and be heated and dried. At the same time, the hot air inside the fixing barrel flows upward to the inside of the screening frame, causing the moisture in the quartz sand to evaporate. When the fan is started, a negative pressure is created inside the heating chamber, which draws the water vapor from the screening frame into the heating chamber. The water vapor then flows upward and is filtered by the filter membrane. The filtered water falls downward from the guide blocks, while the air enters and contacts the heating pipe, thereby improving the energy-saving and environmental protection effect of this high-purity quartz sand drying device.

[0022] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0023] Example 1

[0024] like Figures 1-3As shown, this embodiment provides a high-purity quartz sand drying device, including a shell 1, a feed hopper 2 installed on the top of the shell 1, a screening frame 3 installed inside the shell 1, an isolation plate 17 set in the middle of the shell 1, a fixed barrel 9 installed at the bottom of the isolation plate 17, a screening screen 4 installed inside the screening frame 3, a rotary motor 5 installed on one side of the shell 1, a screen cylinder 6 fixed to the output shaft of the rotary motor 5, and the screen cylinder 6 located inside the fixed barrel 9, scrapers 10 evenly arranged on the outer side of the screen cylinder 6, and a fan 7 installed on the other side of the shell 1, the output end of the fan 7 being fixedly connected to one end of the screen cylinder 6. A heating chamber 11 is installed on one side of the outer casing 1 and above the fan 7. A heating tube 12 is fixed inside the heating chamber 11. A through pipe 8 is fixed at the input end of the fan 7, and the top end of the through pipe 8 passes through and extends into the interior of the heating chamber 11. An air inlet pipe 13 is fixedly connected to one side of the heating chamber 11 and below, and the top end of the air inlet pipe 13 extends to the top of the outer casing 1. A dehumidifying pipe 14 is evenly installed at the bottom of the air inlet pipe 13, and the bottom end of the dehumidifying pipe 14 passes through and extends into the interior of the outer casing 1. A guide block 15 is provided inside the heating chamber 11, and a water filter membrane 16 is provided on one side of the guide block 15.

[0025] The rotary motor 5 is started, and the quartz sand is poured into the feed hopper 2 and enters the screening frame 3. After being filtered by the screening screen 4, it enters the fixed barrel 9. The rotary motor 5 drives the screen cylinder 6 to rotate, and the screen cylinder 6 drives the scraper 10 to rotate, turning the quartz sand inside the fixed barrel 9. At the same time, the blower 7 inputs the air heated by the heating pipe 12 in the heating chamber 11 into the screen cylinder 6 through the pipe 8, and delivers it into the quartz sand through the mesh of the screen cylinder 6 to dry the quartz sand. After the quartz sand enters the screening frame 3, the hot air in the fixed barrel 9 flows upward to the screening frame 3, causing the moisture in the quartz sand to evaporate. When the blower 7 is started, the heating chamber 11 is made negatively pressurized, which draws the water vapor in the screening frame 3 into the heating chamber 11. The water vapor flows upward and is filtered by the water film 16. The filtered water falls downward from the guide block 15, while the air enters and contacts the heating pipe 12.

[0026] Example 2

A support plate 21 is fixed inside the outer shell 1 and below the fixing plate 18. The bottom of the fixing rods 19 passes through and extends to the bottom of the support plate 21.

[0028] The vibration motor 22 is started to drive the screening frame 3. Under the elastic force of the spring 20, the screening frame 3 shakes up and down, causing the quartz sand on the screening screen 4 to shake and be heated and dried. This shakes and screens the quartz sand inside the screening frame 3, further improving the drying efficiency.

[0029] In this embodiment, a discharge pipe is provided at the bottom of the fixed barrel 9, and a valve is provided on the discharge pipe.

[0031] In this embodiment, an arc plate is provided in the middle of the screening frame 3, and guide plates are provided on both sides of the arc plate at an angle.

[0032] The quartz sand entering the screening frame 3 through the feed hopper 2 is dispersed by the arc plate and the guide plate, making it easier for the quartz sand to disperse and come into contact with hot air, thus improving the drying efficiency.

[0033] In this embodiment, a collection frame is slidably installed inside the heating chamber 11 and below the flow guide block 15, and a handle is provided on one side of the collection frame.

[0034] The collection box and the handle on one side make it easy to collect moisture from inside the quartz sand, making the process simpler.

[0035] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
