Description

Technical Field

[0001] This utility model relates to the field of raw material mixing technology, specifically a mixing device for ceramic glaze raw materials. Background Technology

[0002] The building and sanitary ceramics industry places great emphasis on adopting advanced glaze technology. A large number of highly specialized ceramic glaze, ceramic frit, and colorant companies have emerged in China. The glazes used in building and sanitary ceramic products are becoming increasingly diverse, and the glaze products used in most ceramics are also different. In order to obtain better ceramic glazes, a mixer is generally used to stir and mix the raw materials of the ceramic glaze to ensure that the raw materials are mixed evenly. This is the only way to obtain high-quality ceramic glazes. Currently, when adding auxiliary materials to the mixed raw materials, the mixing process is prone to splashing, requiring the machine to be stopped to add the materials, which reduces the mixing efficiency.

[0003] For example, a mixing device for ceramic glaze raw materials disclosed in Chinese patent literature (publication number: CN218981162U) involves adding ceramic glaze raw materials to the main body of the mixing device for stirring. When adding auxiliary materials, the sealing cap is turned to pour the auxiliary materials into the feed port, and then the sealing cap is covered. The baffle is then lifted so that the auxiliary materials flow into the main body of the mixing device for stirring. The baffle is then lowered to prevent the raw materials from splashing out during stirring.

[0004] However, when there is a lot of raw material in the main body of the mixing device, it will cause residual blockage when the auxiliary materials are added through the through hole. Taking the addition of various auxiliary materials such as colorants, fluxes, and opacifiers commonly used in glaze production as an example, it is necessary to repeatedly operate to add various auxiliary materials in sequence according to the time requirements, which greatly increases the problem of manual labor. Utility Model Content

[0005] The purpose of this invention is to provide a mixing device for ceramic glaze raw materials, in order to solve the problem of inconvenience in adding auxiliary materials and increased manual labor during the mixing of existing ceramic glaze raw materials.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mixing device for ceramic glaze raw materials, comprising a mixing tank, wherein a feeding mechanism is provided at the upper end of the mixing tank, and the feeding mechanism includes a rectangular material frame, wherein the lower end of the rectangular material frame is fixedly connected to the upper end of the mixing tank; The rectangular material frame has partition plates arranged in a linear array fixedly connected to its front and rear inner walls. A slot is provided on one side of the rectangular material frame, and a baffle is movably inserted into the inner wall of the slot. One end of the baffle contacts the inner wall of one side of the rectangular material frame, and the front and back of the baffle contact the front and rear inner walls of the rectangular material frame, respectively. A movable plate is fixedly connected to the other end of the baffle. A symmetrically distributed servo electric cylinder is fixedly installed on the front and back of the rectangular material frame, and one end of the piston rod of each of the two servo electric cylinders is fixedly connected to one side of the movable plate. The mixing tank is equipped with a mixing scraping mechanism inside.

[0007] As a further improvement of this utility model: a cover plate is hinged to the back of the rectangular material frame, and the lower end of the cover plate contacts the upper end of the rectangular material frame.

[0008] As a further embodiment of this utility model: the mixing and scraping mechanism includes a hollow rotating tube, the outside of which is rotatably connected to the center of the inner top wall of the mixing tank via a bearing, and the upper end of the hollow rotating tube extends through and to the top of the mixing tank.

[0009] As a further embodiment of this utility model: a worm gear is fixedly sleeved on the upper end of the hollow rotating tube, a first servo motor is fixedly installed on the upper end of the mixing tank, and a worm is fixedly installed on the output shaft of the first servo motor through a coupling, the outer surface of the worm meshing with the tooth surface of the worm gear.

[0010] As a further embodiment of this utility model: the lower end of the hollow rotary tube is fixedly connected to a symmetrically distributed connecting block, and one end of the connecting block is fixedly connected to an arc-shaped scraper, the outer surface of the arc-shaped scraper being in contact with the inner wall of the mixing tank.

[0011] As a further embodiment of this utility model: a mounting bracket is fixedly connected to the upper end of the mixing tank, a second servo motor is fixedly mounted on the upper end of the mounting bracket, and a rotating shaft is fixedly mounted on the output shaft of the second servo motor through a coupling. One end of the rotating shaft passes through the mounting bracket and extends through the hollow rotating tube into the interior of the mixing tank.

[0012] As a further embodiment of this utility model: the rotating shaft is fixedly connected to a stirring blade arranged in a ring array, and a spiral lifting plate is fixedly sleeved on the lower end of the rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this invention, a rectangular material frame in the feeding mechanism, in conjunction with a partition plate, allows multiple auxiliary materials to be pre-separated and stored according to the order of addition. The movement of the baffle is precisely controlled by a servo electric cylinder, which can open the corresponding area as needed, so that the auxiliary materials fall into the mixing tank in an orderly manner, reducing manual intervention and avoiding the problem of frequent machine stoppages for adding auxiliary materials.

[0014] In the mixing and scraping mechanism, the second servo motor drives the rotating shaft and stirring blades to rotate at high speed, which can strongly stir the raw materials. The spiral lifting plate conveys the raw materials at the bottom upwards, forming a three-dimensional circulating stirring effect, ensuring that the raw materials are mixed evenly and improving the quality of ceramic glaze. When discharging, the arc-shaped scraper moves close to the inner wall of the mixing tank, scraping off the material adhering to the tank wall. In conjunction with the opening of the solenoid valve at the bottom of the mixing tank, complete discharge is achieved, reducing material residue. Attached Figure Description

[0019] Reference Figures 1 to 5 In this embodiment of the present invention, a mixing device for ceramic glaze raw materials includes a mixing tank 1. The mixing tank 1 is made of high-strength, corrosion-resistant stainless steel and is precision welded and polished, giving it good sealing and wear resistance. It can effectively resist the erosion of chemical substances in the glaze raw materials and extend the service life of the equipment. A feeding mechanism is provided at the upper end of the mixing tank 1. The feeding mechanism includes a rectangular material frame 2. The rectangular material frame 2 is fixedly connected to the upper end of the mixing tank 1 by welding process to ensure a stable connection and prevent material leakage.

[0020] The front and rear inner walls of the rectangular material frame 2 are fixedly connected by welded partition plates 21 arranged in a linear array. The partition plates 21 divide the interior of the rectangular material frame 2 into multiple independent areas for storing different types of auxiliary materials, which are convenient to be added in the order of the formula. A slot 22 is provided on one side of the rectangular material frame 2. The slot 22 provides guiding space for the movement of the baffle 23. The baffle 23 is movably inserted into the inner wall of the slot 22. One end of the baffle 23 is tightly fitted to one side inner wall of the rectangular material frame 2. Its front and back sides are in contact with the front and rear inner walls of the rectangular material frame 2, respectively, forming a good sealing effect. The other end of the baffle 23 is fixedly connected by welded to a movable plate 24. The front and back sides of the rectangular material frame 2 are fixedly installed with bolts and symmetrically distributed servo electric cylinders 25. One end of the piston rod of each of the two servo electric cylinders 25 is fixedly connected to one side of the movable plate 24. Through the precise drive of the servo electric cylinders 25, the precise movement of the baffle 23 can be realized.

[0021] The mixing tank 1 is equipped with a mixing scraping mechanism.

[0022] A cover plate 26 is hinged to the back of the rectangular material frame 2. The cover plate 26 can be freely rotated around the hinge. When it is necessary to add auxiliary materials, the cover plate 26 can be opened. After the addition is completed, the cover plate 26 is closed. Its lower end is in close contact with the upper end of the rectangular material frame 2, which further enhances the sealing of the feeding mechanism and prevents dust from being blown out and debris from entering.

[0023] The mixing and scraping mechanism includes a hollow rotating tube 3. The outside of the hollow rotating tube 3 is rotatably connected to the center of the inner top wall of the mixing tank 1 through a high-precision bearing. The bearing ensures that the hollow rotating tube 3 rotates flexibly and stably, reducing friction loss. The upper end of the hollow rotating tube 3 passes through and extends to the top of the mixing tank 1, providing an interface for the connection of external transmission components.

[0024] A worm gear 31 is fixedly sleeved on the upper end of the hollow rotating tube 3 by an interference fit. The worm gear 31 is made of high-strength alloy steel and is precision machined, which has good wear resistance and transmission accuracy. A first servo motor 32 is fixedly installed on the upper end of the mixing tank 1 by bolts. The output shaft of the first servo motor 32 is fixedly installed with a worm 33 by a coupling. The worm 33 meshes with the tooth surface of the worm gear 31. Through the worm gear transmission pair, the rotational motion of the first servo motor 32 is transmitted to the hollow rotating tube 3.

[0025] The lower end of the hollow rotating tube 3 is fixedly connected to a symmetrically distributed connecting block 34 by welding. One end of the connecting block 34 is fixedly connected to an arc-shaped scraper 35 by welding. The outer surface of the arc-shaped scraper 35 is in close contact with the inner wall of the mixing tank 1. Driven by the hollow rotating tube 3, the arc-shaped scraper 35 can scrape off the material adhering to the inner wall of the mixing tank 1.

[0026] The upper end of the mixing tank 1 is fixedly connected to the mounting bracket 36 by welding. The mounting bracket 36 provides a stable mounting base for the second servo motor 37. The upper end of the mounting bracket 36 is fixedly mounted with the second servo motor 37 by bolts. The output shaft of the second servo motor 37 is fixedly mounted with a rotating shaft 38 by a coupling. One end of the rotating shaft 38 passes through the mounting bracket 36 and extends through the hollow rotating tube 3 into the interior of the mixing tank 1, providing a power transmission channel for mixing and stirring.

[0027] The outside of the rotating shaft 38 is fixedly connected by welding with stirring blades 39 arranged in a ring array. The shape and angle of the stirring blades 39 are optimized to generate efficient stirring effect on the raw materials during rotation. The lower end of the rotating shaft 38 is fixedly sleeved with a spiral lifting plate 310 by interference fit. Driven by the rotating shaft 38, the spiral lifting plate 310 can transport the raw materials at the bottom of the mixing tank 1 upward, realizing three-dimensional circulation mixing of the raw materials.

[0028] The working principle of this utility model: Step 1: When adding raw materials, the piston rod of the servo electric cylinder 25 extends, driving the moving plate 24 and baffle 23 to the opening of the slot 22. At this time, the operator can pour the basic raw materials of ceramic glaze into the mixing tank 1 through the rectangular material frame 2. After the raw materials are added, the piston rod of the servo electric cylinder 25 retracts, and the baffle 23 re-seals the rectangular material frame 2 to prevent raw materials from splashing during mixing. Subsequently, the operator can add various auxiliary materials from left to right in the rectangular material frame 2 according to the formula requirements, and store them separately through the separator plate 21. Finally, the cover plate 26 is closed, and the second servo motor 37 is started. Its output shaft drives the rotating shaft 38 to rotate through the coupling. The stirring blades 39 on the rotating shaft 38 rotate at high speed to fully stir the raw materials in the mixing tank 1. At the same time, the spiral lifting plate 310 at the lower end of the rotating shaft 38 conveys the raw materials at the bottom upward, so that the raw materials form an up-and-down circulation in the mixing tank 1 to ensure uniform mixing. During this process, the auxiliary materials in the rectangular material frame 2 are stored separately and will not enter the mixing tank 1 in advance. Step two: When additional materials need to be added, the piston rod of the servo electric cylinder 25 extends to a preset length, driving the baffle 23 to move so that one end of the baffle 23 is below the first separator 21. At this time, the additional materials in the first separator area fall into the mixing tank 1 under gravity and mix with the raw materials being stirred. When a second additional material needs to be added, the servo electric cylinder 25 moves again, driving the baffle 23 to continue moving, causing the additional materials in the second separator area to fall into the mixing tank 1. This process is repeated to achieve the timely and orderly addition of multiple additional materials. After the raw materials and auxiliary materials are mixed, the solenoid valve at the bottom of the mixing tank 1 is opened. The mixed materials are discharged through the discharge pipe under the action of gravity. At the same time, the first servo motor 32 is started, and its output shaft drives the worm 33 to rotate. The worm 33 meshes with the worm wheel 31, causing the hollow rotating tube 3 to rotate. This, in turn, drives the connecting block 34 and the arc-shaped scraper 35 to rotate around the inner wall of the mixing tank 1. The arc-shaped scraper 35 scrapes off the material adhering to the tank wall and discharges it through the discharge pipe, ensuring that the material in the mixing tank 1 is completely discharged, preparing for the next mixing operation.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
