Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand processing equipment, in particular to a quartz sand high-temperature purification equipment. Background Art

[0002] The preparation and purification process of high-purity quartz sand includes ore crushing, ore pickling, roasting and water quenching, sand making and screening, magnetic separation (mechanical iron, mica and other impurities), acid flotation and drying (baked sand), magnetic separation (weak magnetic impurities), high-temperature purification and other processes.

[0003] After the pre-treatment, the quartz sand enters the high-temperature calcining furnace for purification. The process is as follows: the feeding equipment transports the quartz sand material to the purification tube in the calcining furnace. Under high temperature conditions, the high-purity quartz sand raw material and the purified gas are fully mixed and reacted to reduce the impurity elements to achieve the purpose of purification.

[0004] In the prior art, the following problems exist during the operation of the calcining furnace:

[0005] The calcining furnace is placed horizontally. In order to improve the feeding and purification effects, the furnace body is tilted and the angle is adjustable. The feeding port of the calcining furnace is larger than the discharging port of the feeding equipment to reserve space for movement, so that the furnace body can still maintain docking with the materials of the feeding equipment during the rotation and tilting process. However, since the position of the feeding equipment is fixed, the rotatable angle of the calcining furnace is limited by the diameter difference between the feeding port of the calcining furnace and the discharging port of the feeding equipment.

[0006] There is only one purification tube for carrying quartz sand in the calcining furnace. After the purification of the quartz sand material in the furnace tube is completed, the material is unloaded for cooling, and then reloaded for high-temperature purification. This cycle operation has low efficiency.

[0007] The two ends of the purification tube carrying quartz sand are set at the two ends outside the furnace body and supported by a tugwheel. The tugwheel abuts against the outer ring surface of the roller on the purification tube and rotates by friction. The purification tube runs at high temperature. Under the action of heat conduction, the temperature of the roller is high, and the tugwheel and the roller surface are in contact and friction. The roller and the tugwheel are in a high temperature working environment, and the tugwheel and the roller wear quickly, affecting the transmission effect.

[0052] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0053] like Figure 1 As shown, a quartz sand high-temperature purification device includes a calcining furnace 2 and a feeding device 1. The feeding device 1 feeds the supporting tube 4 in the calcining furnace 2, and the quartz sand after high-temperature purification is discharged into the cooling device 3 for cooling; at least two supporting tubes 4 are arranged in the calcining furnace 2, and the supporting tubes 4 are extended along the length direction of the calcining furnace 2, and both ends of the supporting tubes 4 extend to the outside of the calcining furnace 2 and are respectively configured as a feeding end 41 and a discharging end 42.

[0054] The calcining furnace 2 is placed horizontally. Under the pushing action of the second pushing mechanism 5, the loading end of the calcining furnace 2 is rotated and tilted upward relative to the unloading end, so that loading and unloading are convenient.

[0055] See attached Figure 2 , the calcining furnace 2 is tilted downward by the pushing action. During the tilting process, the supporting tube 4 and its feeding end 41 are equivalent to moving on an arc trajectory with the feeding end 42 as a fixed point and the length of the supporting tube 4 as a radius. The relative position of the feeding end 41 and the discharge port of the feeding device 1 changes, the height of the feeding end 41 increases, and the horizontal distance increases. Similarly, at the feeding end of the calcining furnace 2, the relative position of the supporting tube 4 and the feeding port of the cooling device also changes.

[0056] In this embodiment, the feeding device 1 and the cooling device 3 are matched with a first pushing mechanism 14 and a third pushing mechanism 8 in a one-to-one manner. Figure 2 Combined with Figure 3The feeding device 1 moves with the calcining furnace 2 under the pushing action of the first pushing mechanism 14, and the cooling device 3 moves with the calcining furnace 2 under the pushing action of the third pushing mechanism 8, so that when the calcining furnace 2 is rotated to any appropriate tilt angle, it can still dock with the devices on both sides to maintain loading and unloading.

[0057] The second pushing mechanism 5 and the third pushing mechanism 8 use lifting cylinders, which are arranged at the bottom of the furnace body of the calcining furnace and the bottom of the box body of the cooling device 3 to lift the whole and change the inclination angle.

[0058] Specifically, as attached Figure 4 As shown in FIG. 1 , the feeding device 1 includes a silo 11 , a feeding pipe 12 , a pipe body bracket 13 , a first pushing mechanism 14 , and an equipment support 15 having horizontal and vertical beams.

[0059] The silo 11 is suspended and fixed above the feeding pipe 12 through an equipment bracket 15. The silo 11 is funnel-shaped, and the discharge end 110 at the bottom of the silo 11 discharges materials vertically. The discharge end 110 of the silo 11 is connected to the loading port of the calcining furnace 2 through the feeding pipe 12, and the tube body bracket 13 provides support and fixation for the feeding pipe 12 at the top; the first pushing mechanism 14 is arranged at the bottom of the tube body bracket 13 and fixedly installed on the equipment bracket 15. The first pushing mechanism 14 drives the tube body bracket 13 and the feeding pipe 12 to move up and down as a whole, so that the discharge pipe mouth of the feeding pipe 12 keeps docking with the loading port of the calcining furnace 2.

[0060] Under the action of the first pushing mechanism 14, the tube bracket 13 and the feeding pipe 12 supported and fixed on the top of the tube bracket 13 move in the vertical direction to change the vertical height to match the height of the loading port of the calcining furnace 2 after it is rotated and tilted.

[0061] In one embodiment, the first pushing mechanism 14 adopts a scissor-type lifting platform, the top plane of the scissor-type lifting platform is directly set as the tube bracket 13 or the frame bracket supporting the tube bracket 13, and the bottom plane of the scissor-type lifting platform is set as a part of the frame body of the equipment bracket 15. The scissor-type bracket is set between the top plane and the bottom plane, and the upper and lower ends of one side of the scissor-type bracket are hinged and rotated at a fixed point, and the upper and lower ends of the other side are installed through a sliding module and slide in the horizontal direction.

[0062] As attached Figure 4 As shown, a stabilizing frame 16 is arranged on the top of the first pushing mechanism 14, and the stabilizing frame 16 is directly connected to the driving end of the first pushing mechanism 14. The tube body bracket 13 is fixed on the stabilizing frame 16 through a support rod 17; guide members 18 are arranged on the frame beams around the equipment support 15, and the four corners of the stabilizing frame 16 are respectively installed on the guide members 18 through guide wheels and can move along the guide members 18. During the lifting and lowering movement of the tube body bracket 13, the guide wheels always move along the guide members to ensure the movement stability.

[0063] The thrust force applied by the first thrust mechanism 14 acts on the stabilizing frame 16, and the four corners of the stabilizing frame 16 move along the guide members to ensure the smooth operation of the upper feeding pipe 12 in receiving and transferring materials, and avoid the thrust force directly acting on the tube body bracket 13 or a part of the feeding pipe 12, which may cause uneven force and lead to unstable equipment.

[0064] In another embodiment, the first pushing mechanism 14 adopts a telescopic cylinder (not shown in the drawings), which is fixed on the equipment bracket 15, and its driving end is connected to the top tube body bracket 13 or the bracket of the tube body bracket 13 to realize the lifting and lowering of the tube body bracket 13 (or the supporting frame of the tube body bracket 13, such as the stabilizing frame 16) and the feeding pipe 12.

[0065] In detail, as attached Figure 5 As shown, the feeding pipe 12 includes an internally connected material receiving portion 121, a transition portion 122 and a material transfer portion 123. The material receiving portion 121 is arranged on one side of the silo 11 to receive materials, the material transfer portion 123 is arranged on one side of the loading port of the calcining furnace 2 to feed materials to the calcining furnace 2, and the transition portion 122 is arranged in a curved pipe shape to adjust the material conveying direction.

[0066] Among them, the outer diameter of the discharge port of the material transfer part 123 is smaller than the caliber of the loading port of the calcining furnace 2, and the discharge port part of the material transfer part 123 is inserted into the loading port of the calcining furnace 2, and the insertion and overlapping arrangement is arranged to compensate for the horizontal position difference caused by the rotation and tilting of the calcining furnace 2, so that the discharge pipe port of the feeding pipe 12 is always connected with the loading port of the calcining furnace 2.

[0067] In one embodiment, the material receiving portion 121 is separately arranged from the material discharging end portion 110 , and the material discharging end portion 110 is arranged opposite to the material receiving portion 121 , and the docking port portions overlap in a sleeve-like manner.

[0068] In detail, the material receiving portion 121 is configured in a funnel shape, the material discharging end portion 110 is configured in a tube shape, and the bottom end of the material discharging end portion 110 is directly inserted into the material receiving portion 121 .

[0069] In another embodiment, the material receiving portion 121 is fixedly connected to the material discharging end portion 110, and the length of the material receiving portion 121 can be telescopically changed with the movement of the tube body bracket 13. The material receiving portion 121 is configured as an elastic telescopic tube (not shown in the drawings), and the elastic telescopic tube is fixedly connected to the material discharging end portion 110.

[0070] Specifically, refer to the attached Figure 4 Combined with Figure 5The tube body bracket 13 is configured as an "I"-shaped bracket, including a U-shaped sliding guide plate 131 and a pair of parallel support plates 132 installed at both ends of the U-shaped sliding guide plate 131; the opening of the U-shaped sliding guide plate 131 is upward, and a vibrator 134 is accommodated in the opening. The vibrator 134 is fixedly connected to the transfer part 123 of the feeding tube 12 through the partition seat 133. When the vibrator 134 is turned on, the feeding tube 12 is vibrated to feed the material.

[0071] After the loading of the support tube 4 is completed, the purified gas is introduced, and the quartz sand and the purified gas are fully mixed and reacted to reduce the impurity elements to achieve the purpose of purification. The support tube 4 is continuously rotated, which helps the quartz sand and the purified gas to fully contact and mix, thereby improving the purification effect.

[0072] The rotary drive mechanism 10 and the transmission mechanism 6 are arranged in pairs, and a set of the rotary drive mechanism 10 and the transmission mechanism 6 is arranged on at least one side of the loading end and the unloading end of the calcining furnace 2, and the rotary drive mechanism 10 is used as a power source to drive the support tube 4 to rotate through the transmission mechanism 6. No matter how many support tubes 4 are arranged, all the support tubes 4 keep running synchronously.

[0073] For ease of understanding, the transmission operation is described in detail below by taking two supporting tubes 4 arranged in parallel as an example.

[0074] Specifically, two supporting tubes 4 are arranged in parallel.

[0075] See attached Figure 6 The transmission mechanism 6 includes a main sprocket 62 carrying a chain 61, a tugwheel 63 and a roller 64 that cooperate with each other. The main sprocket 62 and the tugwheel 63 are coaxially mounted on a rotating shaft 65 and rotate synchronously. The rotary drive mechanism 10 adopts a motor, the driving end of the motor is connected to the rotating shaft 65, and the roller 64 is coaxially mounted on the loading end 41 or the unloading end 42; the rotating shaft 65 is vertically mounted on a pair of parallel support plates 66; the tugwheel 63 is installed between the support plates 66 on both sides, and the main sprocket 62 is installed on the outer side of the support plate 66 on one side.

[0076] The rotary drive mechanism 10 is used as a power source, and the chain 61 and the main sprocket 62 are combined to form a chain loop. A set of rollers 64 and tugs 63 are arranged at each support tube 4 to synchronously drive the two support tubes 4 to rotate around their own central axis. Figure 6 A guide sprocket 67 is provided between the two supporting tubes 4 to guide the chain 61 and avoid interference between the running components.

[0077] When the transmission mechanism 6 is only provided on one side, the feeding end 41 or the unloading end 42 on the other side is supported and driven by the tug 63. Therefore, on the same end side of the calcining furnace 2, all the supporting tubes 4 are driven by the transmission loop of the same chain 61 to rotate synchronously around their own central axis to keep the processing process consistent.

[0078] A cooling water channel 70 is constructed at the bottom of the tugboat 63 through a partition 7 . The partition 7 is in contact with at least the side walls of the support plates 66 on both sides. The tugboat 63 is cooled by water through the cooling water channel 70 .

[0079] In one embodiment, the partition 7 is configured as an independent pipeline, and an independent pipeline is provided between each set of support plates 66 to provide a cooling pipeline, such as the attached Figure 6 In the bottom space between the support plates 66, a partition 7 is arranged, and cooling water is passed through the internal water pipe.

[0080] In another embodiment, the partition 7 is configured as a continuous pipe, and the cavity inside the pipe forms a cooling water path; the continuous pipe is continuously extended with each group of support plates 66 as a support node, and all tugboats 63 share a cooling water path, see the attached Figure 7 .

[0081] Regardless of whether the partition 7 is configured as a continuous pipe or multiple independent short pipes, the side walls of the pipe are in close contact with the side walls of the support plate 66 to form a low-temperature semi-enclosed structural environment to cool the tugboat 63 placed therein. In addition, the close contact of the wall surface can increase the contact area and improve the heat conduction efficiency.

[0082] Furthermore, a thin layer plate 9 is arranged on the top of the partition 7 , and the thin layer plate 9 is arranged as a box-shaped slot frame, the bottom of the tugboat 63 is placed in the box-shaped slot frame, and the side plates on both sides of the thin layer plate 9 are in contact with the support plate 66 .

[0083] The bottom surface of the thin layer plate 9 is in direct or indirect contact with the surface of the partition member 7. Figure 6 A schematic diagram of an implementation method in which the thin layer plate 9 and the partition member are spaced apart is provided.

[0084] The cooling water channel at the bottom provides a cooling source, which changes the support plate 66 and the thin layer plate 9 that are most directly or indirectly attached thereto into a low-temperature environment, shortens the cooling distance between the tugboat 63 and the cooling source, and improves the cooling effect.

[0085] The first pushing mechanism in the feeding equipment provided by the utility model drives the feeding pipe to move up and down. During the angle adjustment process of the calcining furnace, the feeding pipe is lifted and lowered synchronously. The calcining furnace can be rotated and tilted to any required angle, and the discharge end of the feeding equipment can be kept docked with the feed port of the calcining furnace. Similarly, the cooling mechanism as a whole can also move with the calcining furnace through the third pushing mechanism to keep the unloading docking.

[0086] The feeding device provided by the utility model can be equipped with at least two supporting tubes in the calcining furnace. The supporting tubes rotate synchronously through the transmission mechanism, which can purify more quartz sand materials at the same time and improve the processing efficiency. All the supporting tubes share a set of transmission mechanism and rotation drive mechanism, which simplifies the equipment components.

[0087] The transmission mechanism provided by the utility model comprises a meshingly connected chain and a sprocket, a tugwheel and a roller arranged in coordination, the sprocket and the tugwheel are coaxially mounted on a rotating shaft mounted on a pair of support plates, the tugwheel is arranged between the support plates, and a partition is arranged at the bottom of the tugwheel to provide a cooling water path, the partition is at least in contact with the support plates, and the tugwheel, the sprocket and the chain can be cooled in time to extend the service life.

[0088] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
