Description

Technical Field

[0001] This utility model relates to the technical field of refractory material production equipment, and in particular to a microporous lightweight refractory brick production device. Background Technology

[0002] Refractory bricks are shaped refractory materials with standard and regular shapes. According to the manufacturing process, they can be divided into fired bricks, unfired bricks, electrofused bricks, and refractory insulating bricks. According to shape and size, they can be divided into standard bricks, ordinary bricks, and special-shaped bricks. They can be used as high-temperature building materials and structural materials for building kilns and various thermal equipment. They can withstand various physical and chemical changes and mechanical actions at high temperatures. Existing microporous high-temperature lightweight refractory bricks can be made by mixing materials such as pore-forming agents, silica powder, calcium aluminate, kaolin, silica aerogel, and alumina powder. They have the characteristics of being fire-resistant, corrosion-resistant, hard, and not easily deformed. During the processing of refractory bricks, the raw materials are mixed by a mixing device.

[0003] Existing technologies have the following problems: After production, the inner walls of the mixing chamber and the stirring components of existing equipment often require frequent cleaning due to the adhesion of refractory material particles. Currently, the common practice is to manually disassemble the stirring components and scrub them. This operation is not only time-consuming and labor-intensive, but may also lead to contamination of the next batch of materials due to incomplete cleaning, affecting the quality stability of refractory bricks. For example, the device disclosed in the patent application document with application number CN202220755545.3 requires operators to enter the mixing chamber to wipe it, which is inconvenient and poses significant safety hazards. Furthermore, the stirring blades of traditional stirring devices are usually fixed at a certain height, making it impossible to adjust the stirring position according to the amount or characteristics of the material. When processing materials of different batches or volumes, a fixed-height stirring blade may result in insufficient mixing of the upper layer of material and excessive compression of the lower layer of material, leading to poor uniformity of the refractory brick raw material mixing and ultimately affecting the density and refractory performance of the finished product. For example, in the patent application number CN202421193017.9, the stirring structure lacks a height adjustment function, which can easily lead to stirring dead zones when processing high-viscosity materials. The cleaning and stirring processes of existing devices mostly rely on manual intervention and lack an integrated automated control design. This not only increases labor costs but also makes it difficult to achieve standardized and intelligent management of the production process, failing to meet the requirements of modern industrial production for high efficiency and precision.

[0004] To address these shortcomings, we have proposed a microporous lightweight refractory brick production device. Utility Model Content

[0005] The purpose of this invention is to provide a microporous lightweight refractory brick production device to overcome the shortcomings of existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a microporous lightweight refractory brick production device, comprising a mixing box, a box cover detachably mounted on the top of the mixing box by bolts, a bracket fixedly mounted on the top surface of the box cover, a servo electric cylinder fixedly mounted on the top surface of the bracket, a lifting frame mounted on the telescopic end of the servo electric cylinder, a guide groove formed on the surface of the bracket, the lifting frame slidably connected to the guide groove, the telescopic end of the servo electric cylinder fixedly connected to the top surface of the lifting frame, a drive motor fixedly mounted on the top surface of the lifting frame, a rotating rod mounted on the output end of the drive motor, and a stirring blade fixedly mounted on the surface of the rotating rod, a cleaning pump fixedly mounted on the outer wall of the box cover, a cleaning pipe suspended on the inner wall of the box cover, and a cleaning nozzle inclinedly arranged on the surface of the cleaning pipe, the cleaning pipe being connected to the outlet of the cleaning pump via a water pipe.

[0007] The surface of the box cover is fixedly equipped with a feed inlet, and a sealing cap is installed on the feed inlet.

[0008] The bottom surface of the mixing tank is fixedly equipped with support legs, and there are several support legs.

[0009] A control switch is fixedly installed on the outer wall of the mixing tank, and the control switch is electrically connected to the servo cylinder, the cleaning pump and the drive motor through wires.

[0010] The cleaning nozzles are provided in multiples, and the multiple cleaning nozzles are distributed in a ring array on the surface of the cleaning pipe.

[0011] The angle between the cleaning nozzle and the cleaning pipe is 15°-45°.

[0012] A discharge pipe is fixedly installed on the bottom surface of the mixing tank, and a valve is installed on the surface of the discharge pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention incorporates a cleaning pump and cleaning nozzles, enabling a self-cleaning process to be initiated after production. The cleaning pump pressurizes the cleaning fluid and delivers it to each cleaning nozzle through a cleaning pipe. The cleaning nozzles spray high-pressure cleaning fluid onto the inner wall of the mixing tank and the stirring blades, quickly removing adhering material particles. Compared to traditional manual disassembly and cleaning, this design eliminates the need for manual contact with contaminated parts, and the cleaning process is completed automatically. This saves significant cleaning time, reduces the labor intensity of operators, and avoids material contamination caused by incomplete manual cleaning, thereby improving product qualification rates.

[0014] In this invention, the height of the lifting frame can be precisely controlled by a servo electric cylinder, which drives the stirring blade to move up and down in the mixing chamber. When processing materials of different volumes, the height of the stirring blade can be adjusted by a control switch to cover the entire material layer. For example, when the amount of material is small, the stirring blade is lowered to a lower position to ensure that the bottom material is fully mixed. When the amount of material is large, the height of the stirring blade is raised to avoid insufficient mixing of the upper material. This adjustable design greatly improves the uniformity of mixing, effectively solves the dead corner problem of traditional fixed mixing structures, and ensures the consistency of refractory brick raw materials.

[0020] Please refer to Figure 1 and Figure 2A microporous lightweight refractory brick production device includes a mixing chamber 1. A chamber cover 2 is detachably bolted to the top of the mixing chamber 1. A bracket 3 is fixedly mounted on the top surface of the chamber cover 2. A servo cylinder 4 is fixedly mounted on the top surface of the bracket 3. A lifting frame 5 is mounted on the telescopic end of the servo cylinder 4. A guide groove 6 is formed on the surface of the bracket 3. The lifting frame 5 is slidably connected to the guide groove 6. The telescopic end of the servo cylinder 4 is fixedly connected to the top surface of the lifting frame 5. A drive motor 7 is fixedly mounted on the top surface of the lifting frame 5. A rotating rod 8 is mounted on the output end of the drive motor 7, and a stirring blade 9 is fixedly attached to the surface of the rotating rod 8. A cleaning pump 11 is fixedly mounted on the outer wall of the chamber cover 2. A cleaning pipe 12 is suspended on the inner wall of the chamber cover 2. A cleaning nozzle 13 is inclinedly arranged on the surface of the cleaning pipe 12. The cleaning pipe 12 is connected to the outlet of the cleaning pump 11 via a water pipe. Refractory brick raw materials such as pore-forming agent, silica powder, calcium aluminate, kaolin, silica aerogel, and alumina powder are fed through the feed inlet 10. Add the mixture into the mixing tank 1, tighten the sealing cover, and start the servo cylinder 4 via control switch 16. The telescopic end of the servo cylinder 4 drives the lifting frame 5 to slide in the guide groove 6, thereby adjusting the height of the stirring blade 9 to a position suitable for the current material quantity. Then, start the drive motor 7. The output end of the drive motor 7 drives the rotating rod 8 to rotate. The rotating rod 8 drives the stirring blade 9 to stir the material in the mixing tank 1, making the material evenly mixed. After stirring, open the valve on the discharge pipe 15 to discharge the mixed material, and then close the valve on the discharge pipe 15. Start the cleaning pump 11 via control switch 16. The cleaning pump 11 pressurizes the cleaning liquid and delivers it to the cleaning pipe 12 through the water pipe. The cleaning nozzle 13 on the cleaning pipe 12 sprays high-pressure cleaning liquid onto the inner wall of the mixing tank 1 and the stirring blade 9 to clean the inner wall of the mixing tank 1 and the stirring blade 9, removing adhering material particles. After cleaning, turn off the cleaning pump 11. The stirring blade 9 can be adjusted again as needed. The device is cleaned by raising the height of the pump and starting the drive motor 7, which causes the stirring blades 9 to rotate and spin dry the remaining liquid.

[0021] Please refer to Figure 1 and Figure 2 The surface of the box cover 2 is fixedly equipped with a feed inlet 10, and a sealing cover is installed on the feed inlet 10. Through the feed inlet 10, refractory brick raw materials such as pore-forming agent, silica powder, calcium aluminate, and kaolin can be added into the mixing box 1. The sealing cover can prevent the materials from overflowing during the mixing process and prevent dust and other impurities from entering the mixing box 1.

[0022] Please refer to Figure 1As shown in Figure 2, the bottom surface of the mixing box 1 is fixedly equipped with support legs 14, and there are several support legs 14. The support legs 14 are used to support the mixing box 1, so that the mixing box 1 maintains a stable working state. The arrangement of several support legs 14 can evenly distribute the weight of the mixing box 1 and the internal materials, and enhance the stability of the device.

[0023] Please refer to Figure 2 A control switch 16 is fixedly installed on the outer wall of the mixing tank 1. The control switch 16 is electrically connected to the servo cylinder 4, the cleaning pump 11 and the drive motor 7 through wires. The operator can start or stop the servo cylinder 4, the cleaning pump 11 and the drive motor 7 through the control switch 16 to control the lifting and lowering of the stirring blade 9, the cleaning process, etc., and improve the automation level of the device.

[0024] Please refer to Figure 1 and Figure 3 Multiple cleaning nozzles 13 are provided, and the multiple cleaning nozzles 13 are arranged in a ring array on the surface of the cleaning pipe 12. The ring array of multiple cleaning nozzles 13 can make the cleaning liquid evenly sprayed onto the inner wall of the mixing tank 1 and all parts of the stirring blade 9, ensuring that there are no dead corners in the cleaning and improving the cleaning effect.

[0025] Please refer to Figure 1 and Figure 3 The angle between the cleaning nozzle 13 and the cleaning pipe 12 is 15°-45°. This angle allows the cleaning liquid to be sprayed onto the inner wall of the mixing tank 1 and the stirring blade 9 at a suitable angle. This ensures that the cleaning liquid has sufficient impact force to remove adhering material particles and also allows the cleaning liquid to form a good coverage area within the mixing tank 1.

[0026] Please refer to Figure 1 and Figure 2 A discharge pipe 15 is fixedly installed on the bottom surface of the mixing box 1, and a valve is installed on the surface of the discharge pipe 15. After the mixing is completed, the valve on the discharge pipe 15 is opened, and the mixed material can be discharged through the discharge pipe 15 for subsequent refractory brick production processes. The valve can control the discharge speed and discharge volume of the material.

[0027] Working Principle: During use, refractory brick raw materials such as pore-forming agent, silica powder, calcium aluminate, kaolin, silica aerogel, and alumina powder are added to the mixing chamber 1 through the feed inlet 10. The sealing cover is then tightened. The servo cylinder 4 is activated via control switch 16. The telescopic end of the servo cylinder 4 drives the lifting frame 5 to slide within the guide groove 6, thereby adjusting the height of the stirring blade 9 to a position suitable for the current material quantity. Next, the drive motor 7 is activated. The output end of the drive motor 7 drives the rotating rod 8 to rotate, which in turn drives the stirring blade 9 to stir the materials in the mixing chamber 1, ensuring uniform mixing. After stirring, the valve on the discharge pipe 15 is opened to discharge the mixed materials. Then, the valve on the discharge pipe 15 is closed. The cleaning pump 11 is activated via control switch 16. The cleaning pump 11 pressurizes the cleaning liquid and delivers it through a water pipe to the cleaning pipe 12. The cleaning nozzle 13 on the cleaning pipe 12 sprays water onto the inner wall of the mixing chamber 1 and the stirring blade 9. High-pressure cleaning fluid is sprayed to clean the inner wall of the mixing tank 1 and the stirring blade 9, removing adhering material particles. After cleaning, the cleaning pump 11 is turned off. The height of the stirring blade 9 can be adjusted again as needed, and the drive motor 7 can be started to make the stirring blade 9 rotate and spin dry the residual liquid, thus completing the cleaning work of the device.
