Description

Technical Field

[0001] This utility model belongs to the technical field of silicon brick production equipment, specifically relating to a uniform batching and mixing device for the production of high-strength silicon bricks. Background Technology

[0002] Silica bricks are refractory materials made primarily from siliceous materials and fired at high temperatures. They possess high refractoriness, good thermal shock resistance, and strong slag resistance, and are widely used in industrial equipment such as high-temperature smelting furnaces, glass kilns, and ceramic kilns. In the production process of silica bricks, different types of raw materials need to be precisely proportioned and thoroughly mixed to ensure the uniformity and stability of the physical properties and chemical composition of the finished product. The batching and mixing equipment is used to feed, distribute, and mix various materials before silica brick production, ensuring the raw materials achieve a preset level of uniformity, thus providing a stable material base for subsequent molding and firing processes.

[0003] However, there are still some shortcomings in the existing batching and mixing process for silica brick production. First, existing mixers typically introduce different materials sequentially into the mixing chamber through a single inlet, requiring a long stirring time to achieve a uniform effect, and even then, uneven material distribution may still occur. Second, the internal structure of existing mixers is relatively simple, usually only equipped with stirring rods for stirring, lacking optimized control over the movement path of materials during the mixing process. This can easily lead to insufficient mixing in certain areas, affecting the overall quality and performance of the finished silica bricks. Utility Model Content

[0004] This utility model provides a horizontal high-power mixer for mining, which solves the problems mentioned in the background art of existing mixers in silica brick production, such as single feeding method and simple internal structure, resulting in low mixing efficiency and uneven material mixing.

[0005] The technical solution adopted by this utility model is: a uniform batching and mixing device for the production of high-strength silica bricks, including a cylinder, a rotatable main shaft installed inside the cylinder, a spiral blade installed on the outer wall of the main shaft, a top cover installed on the top of the main shaft, and at least two batching mechanisms provided above the top cover. The batching mechanism includes a batching box. Inside the batching box, at the lower part, there are material distribution channels evenly distributed around the center of the batching box. Each material distribution channel is connected to a material distribution pipe at its lower end. The surface of the top cover has multiple inlets evenly distributed around its center. The ends of the material distribution pipes below the batching box are connected to the inlets. The material distribution pipes of different batching mechanisms are staggered on the surface of the top cover. This is designed so that different types of materials enter the corresponding batching boxes and are evenly distributed in their respective batching boxes through different material distribution channels. After being evenly distributed, they are transported to different positions inside the cylinder through the material distribution pipes, so as to achieve uniform feeding of materials inside the cylinder.

[0006] The lower end of the main shaft passes through the bottom of the cylinder and is connected to a drive mechanism.

[0007] The drive mechanism includes a hybrid motor installed on the side of the cylinder. A drive wheel is connected to the output shaft of the hybrid motor, and a driven wheel is connected to the lower end of the main shaft. The drive wheel and the driven wheel are connected by a conveyor belt.

[0008] Several evenly distributed rakes are installed on the outer circumference of the main shaft. The ends of the rakes extend toward the inner wall of the cylinder and are connected to inclined rake teeth.

[0009] The upper end of the main shaft is connected to a first guide component whose upper and lower surfaces are both tapered.

[0010] A second guide component with an overall annular structure and a triangular cross-section is installed above the inner wall of the cylinder.

[0011] Several supports are evenly distributed around the center of the feed box. A feed motor is installed at the center of the supports. The output end of the feed motor is connected to a dispensing shaft, and a dispensing disc is installed on the dispensing shaft.

[0012] The upper surface of the material distribution plate has a conical structure, and several evenly distributed ridges are provided on the upper surface of the material distribution plate, extending from the center of the material distribution plate to the edge.

[0013] A pipe is fixed at the top of the cover, and a nozzle is connected to the pipe, extending into the inner cavity of the cylinder.

[0014] The cylinder has a discharge port on its lower side and a support leg installed at the bottom of the cylinder.

[0015] The beneficial effects of this utility model are as follows: This invention features a feeding mechanism located above the cylinder, allowing materials to first enter the feeding box. The same material can be divided into multiple portions through the feeding channel, and then introduced into different areas of the cylinder through the feeding pipe. The materials are then distributed with other materials in the cylinder at intervals. In this way, the uniformity of material mixing can be achieved quickly during stirring and mixing, and the mixing time can be shortened, thus improving the mixing efficiency.

[0016] This invention features spiral blades on the outer wall of the main shaft, which allow material in the middle position to move upwards when the main shaft rotates. Similarly, the inclined rake teeth cause material at the edge of the cylinder to move upwards. Once the material reaches the upper position, the first and second guide components allow it to move to the area between the center and edge of the cylinder, thereby accelerating the mixing efficiency and further improving the uniformity of the mixture.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As shown in the figure, a uniform batching and mixing device for the production of high-strength silica bricks includes a cylinder 1. A rotatable main shaft 2 is installed inside the cylinder 1. A spiral blade 17 is installed on the outer wall of the main shaft 2. The spiral blade 17 is welded to the outer wall of the main shaft 2 so that the material at the center of the cylinder 1 can move upward under the action of the spiral blade 17 during the rotation of the main shaft 2, so as to achieve a thorough mixing effect. A top cover 13 is installed on the top of the main shaft 2. At least two batching mechanisms 14 are provided above the top cover 13. Since multiple materials need to be mixed in the batching and mixing stage of silica bricks, the number of batching mechanisms 14 can be designed according to actual needs. The batching mechanism 14 includes a batching box 1401. The batching box 1401 has a conical structure in the middle and an opening at the top for introducing materials into the batching box 1401. Inside the lower part of the batching box 1401, there are evenly distributed material distribution channels 1406 around the center of the batching box 1401. Specifically, in this example, there are horizontally and vertically intersecting partitions 1407 at the lower part of the inner cavity of the batching box 1401. The partitions 1407 divide the material discharge channel of the batching box 1401 into four material distribution channels 1406. Materials can enter different material distribution channels 1406 to achieve a material distribution effect. The separated materials then enter different areas within the cylinder 1. It is understood that in other embodiments, different numbers of material distribution channels 1406 can be designed, such as three, five, or six, to meet different material distribution needs.

[0021] Each material distribution channel 1406 is connected to a material distribution pipe 1408 at its lower end. The surface of the upper cover 13 has multiple feed inlets 1301 evenly distributed around its center. The end of the material distribution pipe 1408 below the material distribution box 1401 is connected to the feed inlet 1301. The material distribution pipes 1408 of different material distribution mechanisms 14 are staggered on the surface of the upper cover 13. This is to allow different types of materials to enter the corresponding material distribution box 1401 and be evenly distributed in their respective material distribution boxes 1401 through different material distribution channels 1406. Then, the materials are transported to different positions inside the cylinder 1 through the material distribution pipe 1408 to achieve uniform material distribution inside the cylinder 1.

[0022] The lower end of the main shaft 2 passes through the bottom of the cylinder 1 and is connected to a drive mechanism. Specifically, in this example, the drive mechanism includes a hybrid motor 5 installed on the side of the cylinder 1. The output shaft of the hybrid motor 5 is connected to a drive wheel 6, and the lower end of the main shaft 2 is connected to a driven wheel 9. The drive wheel 6 and the driven wheel 9 are connected by a conveyor belt 8. Both the drive wheel 6 and the driven wheel 9 are synchronous pulleys, and the conveyor belt 8 is a synchronous belt, which is used to improve the efficiency of power transmission.

[0023] Several evenly distributed rakes 3 are installed on the outer circumference of the main shaft 2. The ends of the rakes 3 extend toward the inner wall of the cylinder 1 and are connected to inclined rake teeth 4. The inclined rake teeth 4 can stir and mix the material on the one hand, and drive the material located on the inner wall of the cylinder 1 to move upward, thereby turning the material inside the cylinder 1 and improving the uniformity of the mixture.

[0024] The upper end of the main shaft 2 is connected to a first guide member 11, both of which have conical upper and lower surfaces. The upper surface of the first guide member 11 is set with a conical structure so that the material will not accumulate above the first guide member 11 during the feeding process. The lower surface is set with a conical structure so that when the spiral blades 17 move the material at the center of the cylinder 1 to the top, the material can contact the lower surface of the first guide member 11. The conical structure of the lower surface of the first guide member 11 is used to transfer the material away from the center of the cylinder 1 (i.e., the area between the center of the cylinder 1 and the edge of the cylinder 1) to accelerate the mixing speed.

[0025] A second guide component 12, which has an overall annular structure and a triangular cross-section, is installed above the inner wall of the cylinder 1. It functions similarly to the first guide component 11. Figure 1 As shown, the upper and lower surfaces of the second guide member 12 are inclined. The upper surface is inclined downward from the edge of the cylinder 1 towards the center, and the lower surface is inclined upward. This is so that when the material is moved upward by the rake teeth 4, the material can contact the lower surface of the second guide member 12, thereby transferring the material away from the inner wall of the cylinder 1 (i.e., the area between the center of the cylinder 1 and the edge of the cylinder 1), thus accelerating the mixing speed. The inclined structure of the upper surface of the second guide member 12 is to prevent the material from accumulating on the upper surface of the second guide member 12 during the feeding process.

[0026] Several supports 1402 are evenly distributed around the center of the feeding box 1401. In this example, there are three supports 1402. A feeding motor 1403 is installed at the center of each support 1402. The output end of the feeding motor 1403 is connected to a distributing shaft 1404. A distributing disc 1405 is installed on the distributing shaft 1404. More specifically, the upper surface of the distributing disc 1405 has a conical structure to prevent material from accumulating on the surface of the distributing disc 1405. The upper surface of the distributing disc 1405 is provided with evenly distributed... The fabric has several raised strips 1409, which extend from the center of the distribution plate 1405 to the edge. During operation, the material is first introduced into the batching box 1401, and then the batching motor 1403 drives the distribution plate 1405 to rotate. The material will fall on the rotating distribution plate 1405. Under the action of centrifugal force of the distribution plate 1405, the material can be evenly diffused in all directions, which helps to ensure that the amount of material falling into different distribution channels 1406 below is consistent, and is more conducive to improving the uniformity of feeding.

[0027] A pipe 15 is fixed at the top of the cover 13, and a nozzle 16 is connected to the pipe 15. The nozzle 16 extends into the inner cavity of the cylinder 1. The pipe 15 can be connected to an external pump to spray some liquid raw materials into the cylinder 1 to improve the uniformity of mixing. In this example, there are four nozzles 16.

[0028] The lower side of the cylinder 1 is provided with a discharge port 10, and a support leg 7 is installed at the bottom of the cylinder 1.

[0029] In use, this uniform batching and mixing device for high-strength silica brick production first enters the batching box 1401. The batching motor 1403 above the batching box 1401 drives the distribution plate 1405 to rotate. Under the centrifugal force of the distribution plate 1405 and the guiding action of the protrusions 1409 on its surface, the material is evenly thrown to all sides and falls into multiple distribution channels 1406 located at the bottom of the batching box 1401. The material distributed by the distribution channels 1406 enters the distribution pipe 1408 and is then transported to the corresponding feed inlet 1301 of the upper cover 13. The distribution pipes 1408 of different batching mechanisms 14 are staggered on the surface of the upper cover 13, so that different materials are put into different positions inside the cylinder 1, achieving the initial spatial distribution of raw materials.

[0030] Inside the cylinder 1, a drive mechanism rotates the main shaft 2. The spiral blades 17 on the outer wall of the main shaft 2 convey material at the center of the cylinder 1 upwards. Simultaneously, rakes 3 evenly distributed around the main shaft 2 and their inclined rake teeth 4 flip material near the inner wall of the cylinder 1 upwards, while material between the center and edge of the cylinder 1 moves downwards, achieving three-dimensional circulating mixing. When the spiral blades 17 lift the material upwards, it contacts the lower surface of the first guide member 11 and diffuses away from the center of the cylinder 1 under the guidance of the conical structure, accelerating the outward conveying speed of the central material. Correspondingly, when the rake teeth 4 lift material near the inner wall of the cylinder 1 upwards, the material contacts the lower surface of the second guide member 12 and, under the action of its inclined structure, moves towards the center of the cylinder 1, promoting the interaction and mixing of edge and central materials.

[0031] In addition, the nozzle 16 on the top of the cover 13 can be connected to an external pump to spray the required liquid raw materials into the cylinder 1 in an atomized form, and mix them synchronously with the solid materials to improve the uniformity and binding effect of the mixture. After the mixing is completed, the discharge port 10 on the lower side of the cylinder 1 can be opened to discharge the mixed material for subsequent molding and firing processes.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
