Abstract
Description
Technical Field
[0001] The present application relates to the field of ceramic production equipment, and particularly to a mixing device for ceramic part production. Background Art
[0002] During the production process of ceramic parts, the mixing uniformity of raw materials plays a crucial role in the quality and performance of the final product. Traditional mixing methods often rely on simple stirring or rolling mixing, but these methods are often difficult to achieve an ideal mixing effect when dealing with multiple raw materials with different particle sizes, densities, and humidities. Especially in the preparation of ceramic materials, the mixing uniformity of raw materials is directly related to key performance indicators such as the density, strength, and thermal stability of ceramic parts.
[0003] To solve this problem, people have started to explore more efficient mixing equipment and technologies. However, there are still some limitations in the design and function of existing mixing equipment. For example, the stirring device of some equipment is not reasonably designed, resulting in stirring dead corners during the mixing process, which affects the mixing uniformity; in some other equipment, the cooperation between the support device and the mixing drive device is not tight enough, making the flow of materials in the mixing chamber not smooth enough, further affecting the mixing effect.
[0004] In addition, there are also deficiencies in the pre-treatment and post-treatment of existing mixing equipment. For example, some equipment lacks effective pre-treatment devices, so that the raw materials are not fully settled and wetted before entering the mixing chamber, thus affecting the mixing uniformity and efficiency; at the same time, some equipment lacks a buffer device at the discharge port, resulting in the raw materials being prone to agglomeration during the rapid falling process, further reducing the mixing effect.
[0005] Therefore, there is an urgent need for a new type of mixing device for ceramic part production, which needs to have characteristics such as a reasonable design of the stirring device, a tight cooperation between the support device and the mixing drive device, effective pre-treatment and post-treatment devices, etc., to ensure that the raw materials can be fully and evenly mixed during the mixing process, thereby improving the production quality and efficiency of ceramic parts.

Detailed implementation manners
[0034] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application. It can be understood that the accompanying drawings are only for reference and illustration, and are not used to limit the present application. The connection relationships shown in the drawings are only for clear description and do not limit the connection methods.
[0035] Specifically, as Figures 1-6 shown, an embodiment of the present application provides a mixing device for ceramic part production, which is mainly used for fully mixing ceramic raw materials to facilitate ceramic production.
[0036] In this device, the main body is provided with a cylinder body 100, a mixing chamber 110 is opened in the cylinder body 100, and a feeding port 120 and a discharging port 130 are further provided on the cylinder body 100. Both the feeding port 120 and the discharging port 130 are communicated with the mixing chamber 110, which facilitates the material to enter the mixing chamber 110 from the feeding port 120 and also facilitates the material to be discharged from the cylinder body 100 through the discharging port 130.
[0037] In the embodiment of the present application, there are two feeding ports 120, and both of the two feeding ports 120 are located at the top of the cylinder body 100, which facilitates the material to enter the mixing chamber 110 by its own gravity.
[0038] In the embodiment of the present application, the feeding port 120 is obliquely arranged, and a stirring device 200 is arranged at one side position of the feeding port 120. As Figures 1-2 shown, the stirring device 200 is obliquely arranged at one side position of the feeding port 120. The stirring device 200 includes a stirring rod 210 and a driving member 220. The driving member 220 is mainly set as a driving motor, and the output end of the driving motor is connected with the stirring rod 210. Stirring blades are arranged on the stirring rod 210, and the stirring blades stir and crush the materials at the feeding port 120 under the driving action of the driving motor.
[0039] In the embodiment of the present application, the materials stirred by the stirring blades are mainly raw materials of ceramics, and its main components include kaolin, porcelain clay and other materials. The physical properties and chemical properties of different materials are different. The stirring rod 210 arranged in the present application can thoroughly crush the materials, so as to facilitate the full mixing of the crushed materials in the mixing chamber 110. In order to facilitate the full mixing of the materials, in the embodiment of the present application, one end of the stirring rod 210 is close to one side position of the inner wall of the feeding port 120, and the degree of closeness is close to the abutting degree. At the other end position of the stirring rod 210, it is close to the other side position of the inner wall of the feeding port 120, so that the stirring rod 210 can fully stir and break the materials in the feeding port 120. At the same time, the arrangement of the stirring blades can convey the materials, and the conveying direction is from the direction of the feeding port 120 towards the direction of the mixing chamber 110.
[0040] A supporting device 300 is arranged in the mixing chamber 110. The supporting device 300 supports the materials, which is convenient for the materials to be mixed on the supporting device 300. The supporting device 300 is mainly set as a supporting plate 310 in the embodiment of the present application. The supporting plate 310 is obliquely arranged in the mixing chamber 110, and one end position of the supporting plate 310 is rotationally connected with the cylinder body 100, so that the supporting plate 310 can rotate in the mixing chamber 110.
[0041] A driver 320 is arranged at the position of the supporting plate 310. The fixed end of the driver 320 is arranged at the inner wall position of the top of the mixing chamber 110, and the fixed end of the driver 320 is rotationally connected with the cylinder body 100, which is convenient for the relative rotation of the driver 320 and the cylinder body 100. The output end of the driver 320 is connected with the supporting plate 310, so that the supporting plate 310 can rotate in the mixing chamber 110 through the output end of the driver 320, which is convenient for the supporting plate 310 to process the materials.
[0042] For the effective support of the materials, as Figures 1-3As shown in the figure, in the embodiment of the present application, there are two support plates 310. The two support plates 310 are symmetrically arranged in the mixing chamber 110, and the ends of the two support plates 310 away from the inner wall of the mixing chamber 110 are in contact with each other, so that the internal space of the mixing chamber 110 is separated by the two support plates 310, and a mixing area 111 is formed at the upper position. At the same time, a driver 320 is respectively arranged on the two support plates 310 to drive and adjust the position of the support plates 310.
[0043] In the embodiment of the present application, the driver 320 is set as a hydraulic linear drive. The hydraulic linear drive can adjust the position of the support plate 310 in the mixing chamber 110, which is convenient for supporting and releasing the material.
[0044] The above treatment process mainly includes:
[0045] When the material enters the mixing chamber 110 through the feed inlet 120, since the two support plates 310 are in the lifted state in the initial position, the lifted support plates 310 separate a mixing area 111 in the mixing chamber 110. The material is located in the mixing area 111 and placed on the support plates 310. At this time, the support plates 310 are in a static state;
[0046] When mixing the material, it is necessary to mix the material through the mixing drive device 400. In the embodiment of the present application, the mixing drive device 400 is set as a stirrer. The stirrer is fixedly installed above the cylinder 100, and the part of the stirrer passing through the cylinder 100 is located in the mixing area 111, so that the stirrer can fully stir the material placed above the support plates 310, and the material entering through the feed inlet 120 can be fully stirred by the stirrer.
[0047] During the stirring process in the present application, due to the radius limitation of the output end of the stirrer and the support shape of the support plate 310 being an inverted triangle shape, some positions where the material is placed on the support plate 310 cannot be fully stirred, resulting in the material not being fully mixed. To avoid this situation, a fixing part 420 is fixedly arranged at the end position of the output end of the stirrer. The length of the fixing part 420 extends to the bottommost positions of the two support plates 310, so that the fixing part 420 can penetrate into the piled-up material.
[0048] Since in the embodiment of the present application, the cylinder 100 is integrally set as a cuboid structure, and the support plate 310 is a rectangular structure in the present application, in order to fully mix the material, the mixing drive device 400 performs linear drive on the cylinder 100, so that the mixing drive device 400 moves along the overall structure of the cylinder 100, which is convenient for fully stirring the material on the support plate 310.
[0049] In the embodiment of the present application, a limiting member 410 is also annularly arranged on the output end of the stirrer. The limiting member 410 is of an annular structure on the stirrer and is fixedly connected to the stirrer. When the stirrer rotates, the limiting member 410 rotates synchronously with the stirrer.
[0050] The whole limiting member 410 is arranged in an inverted frustum shape, as Figure 4 shown. The radius of the position of the limiting member 410 facing the feed inlet 120 is larger than the radius of the position of the limiting member 410 away from the feed inlet 120. And the inside of the limiting member 410 is hollow, and at the same time, the limiting member 410 is provided with a hollow-out structure, which facilitates the materials falling on the limiting member 410 to enter the bottommost position of the mixing area 111 to a certain extent.
[0051] In the above, the main body of the limiting member 410 is composed of structures such as steel wires. When the stirrer rotates, the limiting member 410 rotates along with the rotation of the stirrer. Under the rotation of the stirrer and the limiting member 410, the materials can be fully mixed in the mixing area 111.
[0052] In the embodiment of the present application, preferably, a baffle is formed on the periphery of the limiting member 410. The setting of this baffle can make the falling materials enter the position near the stirrer through the restraint of the baffle, so that more materials can be stirred by the stirrer. At the same time, to facilitate more materials to enter near the stirrer, the diameter of the end of the limiting member 410 facing the feed inlet 120 is larger than the distance between the top feed inlet 120.
[0053] Among them, in the embodiment of the present application, a spraying device 500 is also arranged on the cylinder body 100. There are multiple spraying devices 500, and all the multiple spraying devices 500 are arranged at the top position of the mixing cavity 110. When the materials enter the mixing cavity 110 through the feed inlet 120, the spraying device 500 is turned on. On the one hand, it can sediment the suspended materials in the mixing cavity 110, and on the other hand, it can partially moisten the materials above the support plate 310 to perform pre-treatment for the formation of mud in the later stage.
[0054] Among them, to facilitate the discharge of materials from the cylinder body 100, in the embodiment of the present application, the volume ratio of the liquid sprayed by the spraying device 500 to the volume of the materials in the mixing cavity 110 is 5% - 10%.
[0055] A chute 311 is further provided on the support plate 310. The chute 311 is provided at both ends of the support plate 310 on the side away from the mixing area 111. A slider 312 is arranged in the chute 311. The slider 312 is restricted in the chute 311 and slides in the chute 311. An activity plate 150 is abutted and arranged on one side of the slider 312. The activity plate 150 is closely attached to one side of the support plate 310 and is movably connected to the support plate 310.
[0056] In the embodiment of the present application, the middle position of the support plate 310 is set as a hollow structure. A plurality of rollers are arranged side by side in the hollow structure. A groove 313 is formed between the plurality of rollers. The size of the groove 313 allows the material to pass through the groove 313 to pass through the support plate 310.
[0057] In the above, a scraping member 151 is arranged on the activity plate 150 at a position facing the support plate 310 and corresponding to the groove 313. The width of the scraping member 151 is smaller than the width of the groove 313, so that the scraping member 151 can move in the groove 313. When the material is placed on the support plate 310, the movement of the scraping member 151 can scrape the material out of the groove 313, preventing the material from caking in the groove 313 and affecting the functional use of the support plate 310.
[0058] Among them, the movement of the scraping member 151 in the groove 313 is mainly through the movement of the activity plate 150.
[0059] In the embodiment of the present application, the activity plate 150 is pushed by the slider 312 to realize the movement process. Under the pushing of the slider 312, the scraping member 151 on the activity plate 150 linearly moves in the groove 313.
[0060] In the embodiment of the present application, the movement of the slider 312 is through the connection of the sliding plate 140. Specifically:
[0061] As shown in the figure, a sliding plate 140 is arranged at the position between the slider 312 and the discharge port 130. One end of the sliding plate 140 is rotatably connected to the slider 312, and the other end of the sliding plate 140 is rotatably connected to the discharge port 130. The sliding plate 140 itself is set as a solid plate. Through the solid structure of the sliding plate 140, the material can enter the discharge port 130 along the sliding plate 140 and be discharged from the cylinder 100.
[0062] Specifically:
[0063] After the materials are sufficiently stirred and homogenized in the mixing zone 111, the driver 320 is started. The driver 320 pushes the support plate 310 in the mixing chamber 110, so that the end position of the support plate 310 away from the rotation axis of the support plate 310 moves towards the position in the direction of the discharge port 130, facilitating the discharge of the materials from the cylinder 100 through the discharge port 130. At the same time, due to the rotation of the support plate 310, the slide plate 140 arranged between the support plate 310 and the discharge port 130 pushes the slider 312 to move upward in the chute 311. The movement of the slider 312 in the chute 311 pushes the movable plate 150 to move, so that the scraping member 151 on the movable plate 150 scrapes the residual materials on the support plate 310, avoiding the retention of materials on the support plate 310. At the same time, the scraped materials directly pass through the support plate 310 in the direction of the groove 313 and fall to the lower position. At this time, in the embodiment of the present application, a storage box 160 is arranged directly below the support plate 310. When the materials pass through the support plate 310, the materials are exactly located in the storage box 160, facilitating the subsequent processing of the materials in the storage box 160.
[0064] In the above structure, a buffer device 170 is further arranged at the position of the discharge port 130. The buffer device 170 includes a buffer plate 171. A plurality of buffer plates 171 are provided, and the plurality of buffer plates 171 are distributed in a staggered manner in the discharge port 130, so that the falling materials can be buffered by the buffer plates 171 when falling, avoiding the too fast speed of the falling materials.
[0065] In summary, in the embodiment of the present application, the stirring device 200, the support device 300 and the mixing drive device 400 can fully mix and stir the materials. Combining the above structure, the operation in the embodiment of the present application is as follows:
[0066] Different types of materials enter the mixing chamber 110 through one or two feeding ports 120. The stirring device 200 at the position of the feeding port 120 can fully stir and crush the materials, facilitating the mixing of the materials. The rotation of the stirring blades on the stirring device 200 drives the materials to move towards the middle position of the mixing chamber 110, facilitating most of the materials to directly fall onto the limiting member 410. The materials on the limiting member 410 are fully stirred by the stirrer on the mixing driving device 400, facilitating the stirred materials to directly fall onto the support plate 310. At the same time, the falling materials will also be driven by the fixing member 420 to move and undergo three times of stirring to fully process the materials. During the falling process of the materials, a small part of the materials will directly fall onto the support plate 310 without passing through the limiting member 410. At this time, this part of the materials cannot be fully stirred and needs to be recycled and re-stirred. The recycling method is that when the materials are fully stirred, the driver 320 is started. The driver 320 pushes the support plate 310 to rotate, separating the two support plates 310, discharging most of the materials through the discharge port 130. At the same time, the rotation of the support plate 310 drives the slider 312 to move in the chute 311. The slider 312 pushes the movable plate 150 to move upward. The scraping member 151 on the movable plate 150 scrapes the materials on the support plate 310, causing the materials to fall from the groove 313 into the storage box 160. After the storage box 160 is taken out, the materials can be re-stirred fully. This process can ensure the full stirring of the materials.
[0067] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
