Description

Technical Field

[0001] This utility model relates to the field of vacuum degassing mixer technology, specifically to a vacuum degassing mixer with dust recovery function. Background Technology

[0002] Vacuum degassing and mixing equipment is widely used in many fields such as chemical, electronics, food, and pharmaceutical industries due to its superior performance in removing bubbles and homogenizing liquid materials. In addition to degassing, this equipment also has a mixing function, which can thoroughly mix materials of different components.

[0003] However, in actual production processes, dust is easily generated inside the working chamber during operations such as stirring high-hardness powder raw materials and mixing dried materials. This dust adheres to the inner walls of the equipment, is difficult to clean, and is also difficult to collect, resulting in waste.

[0004] Therefore, based on this, a design or technical improvement is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned shortcomings and provide a vacuum degassing and mixing device with dust recovery function.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A vacuum degassing and mixing device with dust recovery function includes a vacuum degassing and mixing body, a working chamber is provided on the vacuum degassing and mixing body, a support frame is fixedly provided on the vacuum degassing and mixing body, and a cylinder is fixedly provided on the support frame. An adsorption cover is fixedly connected to the bottom end of the cylinder, and a cover is fixedly provided on the adsorption cover.

[0008] A shell is fixedly installed on one side of the vacuum degassing and stirring body, and a fan is fixedly installed inside the shell. A shell is fixedly installed in the middle of the inner wall of the shell, and the top of the shell is connected to a rubber air pipe. One end of the rubber air pipe is connected to the adsorption hood, and a dust collection bag is installed at the end of the rubber air pipe. An air outlet is opened at the bottom of the shell, and a first filter plate is fixedly installed inside the shell.

[0009] The cover is equipped with a cleaning mechanism for cleaning the inner wall of the working chamber;

[0010] The vacuum degassing and stirring body is equipped with a stirring component for stirring materials.

[0011] Furthermore, the cover has a cavity, and the inner wall of the cover has a limiting groove. A positioning ring is fixedly installed in the cavity. The cleaning mechanism includes a toothed ring that is rotatably installed in the limiting groove. The bottom end of the toothed ring is fixedly connected to an annular tube. Multiple sets of sleeves are fixedly installed on the outer surface of the annular tube. A round rod is slidably installed in each of the multiple sets of sleeves. A round plate is fixedly installed at one end of the round rod, and a brush is fixedly installed at one end of the round plate.

[0012] Furthermore, a protective tube is fixedly installed between the cover and the positioning ring, and a first motor is fixedly installed at the top of the cover. The output shaft of the first motor is fixedly connected to a shaft rod, and the shaft rod passes through the protective tube. A gear is fixedly installed at the end of the shaft rod, and the gear meshes with the gear ring.

[0013] Furthermore, the stirring assembly includes a second motor mounted on the vacuum degassing stirring body, and the output shaft of the second motor is fixedly connected to a rotating plate, with multiple sets of stirring blades fixedly installed on the top of the rotating plate.

[0014] Furthermore, a spring is fixedly connected to one side of the circular plate, and the end of the spring is fixedly connected to the outer surface of the annular tube.

[0015] Furthermore, a second filter plate is fixedly installed inside the cover.

[0016] Furthermore, multiple sets of limiting rods are slidably installed on the outer surface of the support frame, and the bottom ends of the multiple sets of limiting rods are fixedly connected to a cover.

[0017] Furthermore, the outer casing is fixedly connected to a mounting plate by multiple sets of bolts.

[0018] Compared with existing technologies, the beneficial effects of this solution are:

[0019] 1. By activating the drive cylinder, the sealing cap closes to the top of the working chamber, forming a sealed structure that effectively prevents dust and debris from leaking out. This creates an ideal closed environment for subsequent cleaning work, ensuring both safety and environmental friendliness. After the fan is turned on, the rubber hose and adsorption hood work together to quickly collect residual dust, debris, and other impurities inside the working chamber into a dust bag, achieving initial deep cleaning. As the cylinder is activated again to lower the sealing cap, the adsorption hood descends simultaneously, allowing for a more thorough adsorption of the bottom of the working chamber.

[0020] 2. The first motor drives the shaft and gear to rotate, which in turn drives the gear ring and annular tube to rotate, so that the brush can fully contact the inner wall of the working chamber and brush off stubborn dust and stains. It can comprehensively and efficiently remove various impurities in the working chamber, greatly improve the cleaning quality, and provide a strong guarantee for the stable operation of the equipment and subsequent production.

[0031] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] like Figure 1-7 The vacuum degassing and mixing equipment with dust recovery function shown includes a vacuum degassing and mixing body 1, a working chamber 2 on the vacuum degassing and mixing body 1, a support frame 3 fixedly mounted on the vacuum degassing and mixing body 1, and a cylinder 5 fixedly mounted on the support frame 3. An adsorption hood 6 is fixedly connected to the bottom end of the cylinder 5, and a cover 7 is fixedly mounted on the adsorption hood 6. A shell 9 is fixedly mounted on one side of the vacuum degassing and mixing body 1, and a fan 912 is fixedly mounted inside the shell 9. A [missing information - likely a device or component] is fixedly mounted in the middle of the inner wall of the shell 9. The outer shell 9 has a rubber air pipe 8 connected to its top end. One end of the rubber air pipe 8 is connected to the adsorption cover 6. A dust collection bag 915 is provided at the end of the rubber air pipe 8. An air outlet 913 is provided at the bottom of the outer shell 9. A first filter plate 914 is fixedly installed inside the outer shell 9. The first filter plate 914 plays a filtering role to prevent dust from entering the fan 912. A cleaning mechanism is provided on the cover 7 for cleaning the inner wall of the working chamber 2. A stirring component is provided on the vacuum degassing stirring body 1 for stirring the material.

[0033] In one embodiment, a cavity 611 is provided on the cover 7, and a limiting groove 712 is provided on the inner wall of the cover 7. A positioning ring 613 is fixedly installed in the cavity 611. The cleaning mechanism includes a toothed ring 512 rotatably disposed in the limiting groove 712, and an annular tube 511 is fixedly connected to the bottom end of the toothed ring 512. Multiple sets of sleeves 414 are fixedly installed on the outer surface of the annular tube 511. A round rod 413 is slidably disposed in each of the multiple sets of sleeves 414. A round plate 412 is fixedly installed at one end of the round rod 413, and a brush 411 is fixedly installed at one end of the round plate 412. The limiting groove 712 ensures that the toothed ring 512 remains stable during rotation and does not undergo radial displacement, thereby ensuring the stability and reliability of the cleaning work of the brush 411.

[0034] In one embodiment, a protective tube 612 is fixedly installed between the cover 7 and the positioning ring 613. The positioning ring 613 increases the stability of the protective tube 612. A first motor 811 is fixedly installed at the top of the cover 7. The output shaft of the first motor 811 is fixedly connected to a shaft 812, and the shaft 812 passes through the protective tube 612. A gear 813 is fixedly installed at the end of the shaft 812, and the gear 813 meshes with the gear ring 512. By driving the first motor 811, the shaft 812 rotates, causing the gear 813 to rotate, so that the annular tube 511 rotates synchronously, and the brush 411 rotates for cleaning.

[0035] In one embodiment, the stirring assembly includes a second motor 211 disposed on the vacuum degassing stirring body 1, and the output shaft of the second motor 211 is fixedly connected to a rotating plate 212. Multiple sets of stirring blades 213 are fixedly installed on the top of the rotating plate 212. By driving the second motor 211, the rotating plate 212 drives the multiple sets of stirring blades 213 to rotate, thereby stirring the material.

[0036] In one embodiment, a spring 415 is fixedly connected to one side of the circular plate 412, and the end of the spring 415 is connected to the outer surface of the annular tube 511. The elastic deformation characteristics of the spring 415 enable the circular plate 412 to drive the brush 411 to extend and retract flexibly, ensuring that the brush 411 will not detach from the bin wall and always maintain effective contact.

[0037] In one embodiment, a second filter plate 711 is fixedly installed inside the cover 7. The second filter plate 711 prevents large debris from entering the gas tube 8 and prevents blockage.

[0038] In one embodiment, multiple sets of limiting rods 4 are slidably mounted on the outer surface of the support frame 3, and the bottom ends of the multiple sets of limiting rods 4 are fixedly connected to the cover 7. When the drive cylinder 5 drives the cover 7 to rise and fall, the limiting rods 4 slide along the support frame 3 to guide the cover 7 and prevent the cover 7 from tilting, shifting, or shaking during the rising and falling process. This ensures that the cover 7 can accurately and stably close to the top of the working chamber 2, forming a good sealing effect.

[0039] In one embodiment, a mounting plate 911 is fixedly connected to the upper part of the outer casing 9 by multiple sets of bolts 311. The outer casing 9 can be easily disassembled by simply unscrewing the bolts 311, making it convenient to replace the dust collection bag 915 inside the outer casing 9.

[0040] The specific workflow of this plan is as follows:

[0041] First, the drive cylinder 5 is activated. The piston rod of cylinder 5 extends downward, pushing the cover 7 to descend smoothly. When the cover 7 accurately closes on the top of the working chamber 2, a sealing structure is formed between the two, preventing dust and debris from leaking out during operation and providing a closed environment for subsequent work.

[0042] Then, the second motor 211 on the vacuum degassing and stirring body 1 is started. The output shaft of the second motor 211 drives the fixedly connected rotating plate 212 to start rotating. The multiple sets of stirring blades 213 fixedly installed at the top of the rotating plate 212 rotate synchronously to stir the material in the working chamber 2.

[0043] When dust collection is required after the mixing operation, the fan 912 inside the outer casing 9 is turned on, and the fan 912 runs at high speed to generate strong suction. The suction is transmitted to the adsorption hood 6 through the rubber air tube 8, and the adsorption hood 6 begins to adsorb residual dust, debris and other impurities inside the working chamber 2. These impurities are collected into the dust collection bag 915 through the rubber air tube 8.

[0044] While the adsorption operation continues, cylinder 5 is driven again, causing the cover 7 to slowly move towards the bottom of the working chamber 2. During this process, the position of the adsorption hood 6 descends with the cover 7, enabling deeper adsorption at the bottom of the working chamber 2. Simultaneously, the first motor 811 on the cover 7 is activated, driving the shaft 812 to rotate, and the gear 813 at the end of the shaft 812 rotates accordingly. The gear 813 meshes with the gear ring 512, and the rotation of the gear 813 drives the gear ring 512 to rotate around the central axis of the working chamber 2. The gear ring 512 is fixedly connected to the annular tube 511, thereby driving the annular tube 511 to rotate synchronously. During the rotation, multiple sets of brushes 411 evenly distributed on the annular tube 511 fully contact the inner wall of the working chamber 2, brushing off stubborn dust and stains adhering to the chamber wall.

[0045] When the brush 411 contacts the inner wall of the working chamber 2 for cleaning, the circular plate 412 is connected to the annular tube 511 through the spring 415. The spring 415 has a certain elastic deformation capability, ensuring that the brush 411 always fits tightly against the inner wall of the working chamber 2 and maintains a high-efficiency cleaning effect.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
