Description

Technical Field

[0001] This application relates to the field of quartz sand processing, and more specifically, to a calcination apparatus for purifying quartz sand. Background Technology

[0002] Quartz sand is quartz particles produced by crushing and processing quartz stone. It is an important industrial mineral raw material, widely used in glass, casting, ceramics and fireproof materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter media, etc. In order to improve the utilization rate of quartz sand, it is necessary to calcine it at high temperature to remove volatile components, including hydroxyl groups.

[0003] Existing calcination devices for purifying quartz sand mostly adopt a fixed support structure, which cannot flexibly adjust the tilt angle of the outer cylinder according to the material characteristics or process requirements. As a result, the calcined quartz sand tends to accumulate at the bottom of the cylinder and is difficult to completely discharge. This design not only increases the difficulty of manual cleaning, but may also cause secondary pollution or equipment corrosion due to material residue. Therefore, a calcination device for purifying quartz sand is needed to help solve this problem. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] The purpose of this application is to address the shortcomings of existing technologies by providing a calcination device for purifying quartz sand. This addresses the problem that most existing calcination devices for purifying quartz sand use a fixed support structure, which cannot flexibly adjust the tilt angle of the outer cylinder according to the material characteristics or process requirements. As a result, the calcined quartz sand tends to accumulate at the bottom of the cylinder and is difficult to completely discharge. This design not only increases the difficulty of manual cleaning but may also cause secondary pollution or equipment corrosion due to material residue.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A calcination apparatus for purifying quartz sand includes a first base frame, a second base frame installed at the bottom of the first base frame, the first base frame and the second base frame being fixed together by hinges, a support cavity being provided on the side of the second base frame, a support component for assisting the support of the first base frame being installed in the support cavity, an outer cylinder being installed at the top of the first base frame, a calcination cylinder being rotatably disposed inside the outer cylinder, a receiving cavity being provided inside the calcination cylinder, a collection funnel for assisting feeding being installed at one end of the outer cylinder corresponding to the calcination cylinder, and a feed port communicating with the collection funnel being installed at the top of the outer cylinder;

[0008] One end of the outer cylinder is equipped with a servo motor that drives the calcining cylinder to rotate. A coupling is fixed to the front end of the servo motor. A fixing frame is fixed inside the calcining cylinder. The coupling and the fixing frame are connected and fixed by a connecting rod. A sealing plate is hinged to the end of the outer cylinder away from the servo motor. A protruding seat is provided on the outer side of the outer cylinder. A fixing component for fixing the sealing plate is installed on the protruding seat.

[0009] Furthermore, the support assembly includes a sliding block slidably disposed within the support cavity, a support rod is hinged between the first base frame and the sliding block, and an electric actuator for assisting the movement of the sliding block is installed on the side of the second base frame corresponding to the side of the support cavity.

[0010] Furthermore, a spiral heating wire is fixed to the inner edge of the outer cylinder, and the heating wire is fixedly connected by a fixing clamp.

[0011] Furthermore, a tilting plate is fixedly inclined inside the calcination cylinder cavity, and several tilting plates are arranged in a circular array with the axis of the cavity as the center.

[0012] Furthermore, a rotating guide rail is fixed on the outer side of the calcining cylinder, and a guide wheel is installed on the inner side of the outer cylinder, with the guide wheel and the rotating guide rail sliding together.

[0013] Furthermore, the fixing assembly includes a hinge seat hinged to the sealing plate and a hook fixed to the protruding seat. A pressing plate is hinged to the hinge seat, and a hanging ring is hinged to the pressing plate. The hanging ring and the hook are fixed together.

[0014] Furthermore, leveling knobs are installed at the four corners of the bottom of the second base frame, and the second base frame is threadedly connected to the leveling knobs.

[0015] The beneficial effects of this application are as follows: by setting up a support component, the support component drives the sliding block to move through the electric push rod, and cooperates with the support rod to achieve precise adjustment of the angle between the first base frame and the second base frame, so that the outer cylinder reaches a suitable tilt angle for material discharge, thereby improving the adaptability of the device to different operating requirements and the structural support stability, and avoiding problems such as the inability of materials inside the calcining cylinder to be effectively discharged.

[0016] The spiral heating wires are evenly distributed along the inner edge of the outer cylinder, and the fixing clamps ensure that the heating elements are firmly installed, forming a continuous and uniform heating area. This effectively improves the calcination efficiency of quartz sand and avoids local overheating. The sliding fit structure between the rotating guide rail and the guide wheel reduces the frictional resistance when the calcination cylinder rotates, reduces mechanical wear, and extends the service life of the equipment.

[0029] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Reference Figure 1-4 As shown, this utility model provides a calcination device for purifying quartz sand, including a first base frame 1, an outer cylinder 6 installed at the top of the first base frame 1, a calcination cylinder 9 rotatably arranged inside the outer cylinder 6, a receiving cavity opened inside the calcination cylinder 9, a collection funnel 8 for auxiliary feeding installed inside the outer cylinder 6 corresponding to one end of the calcination cylinder 9, a feed inlet 14 communicating with the collection funnel 8 installed at the top of the outer cylinder 6, a servo motor 4 for driving the calcination cylinder 9 to rotate installed at one end of the outer cylinder 6, a coupling 5 fixed at the front end of the servo motor 4, a fixing frame 52 fixed inside the calcination cylinder 9, the coupling 5 and the fixing frame 52 being connected and fixed by a connecting rod 51, and a tilting plate 10 being tilted and fixed inside the receiving cavity of the calcination cylinder 9, a plurality of tilting plates 10 being arranged in a circular array with the axis of the receiving cavity as the center.

[0031] The quartz sand is continuously agitated by the rotating plates 10 in the annular array inside the calcining cylinder 9 during rotation, allowing the material to fully contact the heat source, promoting the effective separation of impurities from the quartz sand, and improving the purification effect.

[0032] A spiral heating wire 13 is fixed at the inner edge of the outer cylinder 6. The heating wire 13 is fixedly connected by a fixing clamp. A rotating guide rail 12 is fixed on the outer side of the calcining cylinder 9. A guide wheel 11 is installed on the inner side of the outer cylinder 6. The guide wheel 11 and the rotating guide rail 12 slide together.

[0033] The spiral heating wires 13 are evenly distributed along the inner edge of the outer cylinder 6, and the fixing clamps ensure that the heating elements are firmly installed, forming a continuous and uniform heating area. This effectively improves the calcination efficiency of quartz sand and avoids local overheating. The sliding fit structure between the rotating guide rail 12 and the guide wheel 11 reduces the frictional resistance when the calcination cylinder 9 rotates, reduces mechanical wear, and extends the service life of the equipment.

[0034] The first base frame 1 is mounted at the bottom of the second base frame 2. The first base frame 1 and the second base frame 2 are fixed together by a hinge. A support cavity is provided on the side of the second base frame 2. A support component 15 is installed in the support cavity to assist the support of the first base frame 1. The support component 15 includes a sliding block 16 that is slidably disposed in the support cavity. A support rod 18 is hinged between the first base frame 1 and the sliding block 16. An electric push rod 17 that assists the movement of the sliding block 16 is installed on the side of the second base frame 2 corresponding to the side of the support cavity.

[0035] The support component 15 is set up, and the sliding block 16 is driven to move by the electric push rod 17. In conjunction with the support rod 18, the angle between the first base frame 1 and the second base frame 2 is precisely adjusted so that the outer cylinder 6 reaches a suitable tilt angle for material discharge. This improves the adaptability of the device to different operating requirements and the structural support stability, and avoids problems such as the inability of materials inside the calcining cylinder 9 to be effectively discharged.

[0036] Furthermore, each of the four corners of the bottom of the second base frame 2 is equipped with a leveling knob 3. The second base frame 2 and the leveling knob 3 are threaded together. By adjusting the height of the four corners through the leveling knob 3, the device can maintain a horizontal and stable state even on uneven ground. This enhances the adaptability of the equipment to complex working environments, ensures the safe and reliable operation of the calcination process, and avoids excessive shaking of the device.

[0037] Furthermore, a sealing plate 7 is hinged to the end of the outer cylinder 6 away from the servo motor 4. A protruding seat is provided on the outer side of the outer cylinder 6. A fixing component 19 for fixing the sealing plate 7 is installed on the protruding seat. The fixing component 19 includes a hinge seat 20 hinged to the sealing plate 7 and a hook 23 fixed to the protruding seat. A pressing plate 21 is hinged to the hinge seat 20. A hanging ring 22 is hinged to the pressing plate 21. The hanging ring 22 and the hook 23 are fixed together.

[0038] Through the cooperation between the sealing plate 7 and the fixing component 19, the fixing component 19 achieves rapid opening and closing and firm fixation of the sealing plate 7 through the linkage design of the hinge seat 20, the pressing plate 21, the hanging ring 22 and the hook 23, ensuring the sealing of the cavity during the calcination process, preventing heat loss and material leakage, and facilitating the quick disassembly of the sealing plate 7 in subsequent work to facilitate material discharge.

[0039] Working principle: This calcination device for purifying quartz sand...

[0040] Quartz sand enters the calcining cylinder 9 through the inlet 14 and the collection funnel 8. The servo motor 4 drives the fixed frame 52 to rotate through the coupling 5 and the connecting rod 51, driving the calcining cylinder 9 to rotate inside the outer cylinder 6. The rotating guide rail 12 and the guide wheel 11 slide to ensure the smoothness of rotation. The spiral heating wire 13 inside the outer cylinder 6 is fixed by the fixing clamp. After being energized, it forms a uniform heat field to heat the calcining cylinder 9.

[0041] The rotating plates 10 in the annular array inside the calcining cylinder 9 continuously agitate the quartz sand during rotation, promoting heat penetration and impurity separation. After calcination, the fixing component 19, through the hinge seat 20, the pressing plate 21, the linkage hanging ring 22, and the hook 23, enables the sealing plate 7 to be opened and closed quickly and firmly fixed, ensuring the cavity is airtight.

[0042] During material discharge, the support assembly 15 drives the sliding block 16 to move through the electric push rod 17 in the support cavity of the second base frame 2, and supports the first base frame 1 to a preset tilt angle via the support rod 18, so that the outer cylinder 6 forms an tilted state that facilitates material discharge.

[0043] The leveling knobs 3 at the bottom of the second base frame 2 adjust the height of the four corners through threaded engagement, adapting to different ground conditions and ensuring the horizontal stability of the equipment.
