[0003] After the preliminary treatment, the quartz sand enters the high-temperature purification furnace for purification. The process is as follows: the feeding equipment transports the quartz sand material to the purification tube in the purification 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 order to facilitate loading and unloading, the purification furnace is placed horizontally, and in order to improve the feeding and purification effects, the furnace body can be rotated and tilted. The feed port of the purification furnace is larger than the discharge port of the loading equipment to reserve space for movement, so that the furnace body can still maintain docking with the material of the loading equipment during the rotation and tilting process.

[0005] However, due to the fixed position of the feeding equipment, the rotation angle of the purification furnace is limited by the diameter difference between the feeding port of the purification furnace and the feeding port of the feeding equipment; if the feeding port of the purification furnace is too large, it is easy to overflow, and it will affect the sealing of the purification furnace, the temperature and heat will be lost, and the calcination quality of quartz sand will be affected.

[0027] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0028] like Figure 1 As shown, a feeding mechanism of a high-temperature purification furnace comprises a silo 2, a feeding pipe 1 and a driving mechanism 6. The discharge end 20 of the silo 2 is connected to the feeding port of the purification furnace 3 through the feeding pipe 1, and the feeding pipe 1 is supported and fixed by a tube bracket 4 at the bottom.

[0029] The purification furnace 3 is placed horizontally, and under the pushing action of the push mechanism 5, the loading end of the purification furnace 3 is rotated and tilted upward relative to the unloading end, which is convenient for loading. The push mechanism 5 adopts a lifting cylinder and is installed at the bottom of the furnace body of the purification furnace 3.

[0030] In this embodiment, the silo 2 is suspended and fixed above the feeding pipe 1 by means of the equipment bracket 7. Figure 2 The silo 2 is funnel-shaped, and the discharge end 20 at the bottom of the silo discharges materials vertically. Under the action of the driving mechanism 6, the tube bracket 4 and the feeding pipe 1 supported and fixed on the top of the tube bracket 4 move in the vertical direction to change the vertical height to match the height of the feeding port of the purification furnace 3 after rotation and tilting. The driving mechanism 6 is connected to the tube bracket 4 and acts on the tube bracket 4.

[0031] Specifically, refer to the attached Figure 3 Combined with Figure 5The tube body bracket 4 is configured as an "I"-shaped bracket, including a U-shaped sliding guide plate 41 and a pair of parallel support plates 42 installed at both ends of the U-shaped sliding guide plate 41; the opening of the U-shaped sliding guide plate 41 is upward, and a vibrator 8 is accommodated in the opening. The vibrator 8 is fixedly connected to the transfer part 13 of the feeding tube 1 through a partition seat 43. When the vibrator 8 is turned on, the feeding tube 1 is vibrated to feed the material.

[0032] In one embodiment, the driving mechanism 6 adopts a scissor lift. Figure 3 Combined with Figure 5 The top plane of the scissor lift is directly set as the tube bracket 4 or the frame bracket supporting the tube bracket 4, and the bottom plane of the scissor lift is set as a part of the frame body of the equipment bracket 7. The scissor-shaped bracket is set between the top plane and the bottom plane. The upper and lower ends of one side of the scissor-shaped 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, thereby driving the top feeding pipe 1 to move up and down.

[0033] In the application scenario, a vertical guide member 10 is fixed on the equipment support 7, and guide wheels attached to at least two side surfaces of the guide member 10 are installed on the tube bracket 4. During the lifting and lowering movement of the tube bracket 4, the guide wheels always move along the guide members to ensure the movement stability. Of course, the tube bracket 4 is also installed on the mobile frame 9 (the mobile frame 9 serves as the top plane of the scissor-shaped lifting platform), and then the guide wheels that cooperate with the guide member 10 can be set on the mobile frame 9.

[0034] In another embodiment, the driving mechanism 6 adopts a telescopic cylinder (not shown in the drawings), which is fixed on the equipment bracket 7, and its driving end is connected to the top tube body bracket 4 or the bracket of the tube body bracket 4 (such as the mobile frame 9), so as to realize the lifting and lowering of the tube body bracket 4 (and the mobile frame 9) and the feeding pipe 1.

[0036] Among them, the outer diameter of the discharge port of the material transfer part 13 is smaller than the caliber of the loading port of the purification furnace 3, and the discharge port of the material transfer part 13 is partially inserted into the loading port of the purification furnace 3, and the insertion and overlapping arrangement is arranged to compensate for the horizontal position difference caused by the rotation and tilt of the purification furnace 3, so that the discharge pipe port of the feeding pipe 1 is always connected with the loading port of the purification furnace 3.

[0037] In one embodiment, the material receiving portion 11 and the material discharging end portion 20 are separately arranged, and the material discharging end portion 20 is arranged opposite to the material receiving portion 11 and the docking port portions overlap in a sleeve-like manner.

[0038] In detail, as attached Figure 4 As shown, the material receiving portion 11 is configured in a funnel shape, the material discharging end portion 20 is configured in a tube shape, and the bottom end of the material discharging end portion 20 is inserted directly into the material receiving portion 11 .

[0039] In another embodiment, the material receiving portion 11 is fixedly connected to the material discharging end portion 20, and the length of the material receiving portion 11 can be telescopically changed with the movement of the tube body bracket 4. The material receiving portion 11 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 20.

[0040] The present application is used for feeding quartz sand into a high-temperature purification furnace. The discharge end of the feeding device follows the rotation and inclination of the purification furnace. Regardless of the inclination angle of the purification furnace, the discharge end of the feeding device and the feed port of the purification furnace are always connected.

[0041] 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.
