[0001] The utility model belongs to the technical field of mixing devices, and particularly relates to a premixing device for castable with a dust recovery structure. Background Art

[0002] A premixing device for castable is a device used to mix different components (such as aggregates, powders, binders, etc.) in proportion, and is widely used in industries such as construction, metallurgy, and ceramics. This device can ensure the uniformity and stability of the castable, thereby improving the performance of the final product. The premixing device is usually equipped with an automatic control system to precisely control the mixing process and achieve efficient production. In the existing premixing devices for castable, during the mixing and conveying processes, the equipment will have dust leakage, resulting in environmental pollution and safety hazards. The conventional solution is to install an efficient dust removal device on the equipment to ensure timely capture and treatment of dust during the mixing and conveying processes. However, the drawback of this method is that the complex design of the equipment may increase the maintenance difficulty, and professional personnel are required for operation and management. At the same time, the dust cannot be recycled. Therefore, a new structure is proposed to solve the above problems. Content of the Utility Model

Six groups of installation holes 190 are equidistantly opened at the top of the fixed ring 170 with the center of the circle as the base point;

[0025] A clamping ring 180 is provided below the fixed ring 170. The clamping ring 180 is made of rubber. A collection mechanism 160 is provided inside the fixed ring 170. The collection mechanism 160 is composed of an installation ring 200, a stabilizing ring 210, and a collection cloth bag 220. Six groups of installation cylinders 240 are equidistantly provided in the annular area away from the center of the circle of the installation ring 200. Two groups of handles 230 are equidistantly provided at the top of the installation ring 200.

[0026] Both the installation ring 200 and the stabilizing ring 210 are made of stainless steel. The bottom of the installation ring 200 is welded and fixed to the top of the stabilizing ring 210. The inner sides of the installation ring 200 and the stabilizing ring 210 are adhesively fixed to the outer side of the collection cloth bag.

[0028] The radius length of the installation ring 200 is greater than the radius length of the fixed ring 170. The tops of the installation cylinders 240 are respectively welded and fixed to the bottom of the installation ring 200. The bottom of the installation cylinder 240 is a hemispherical structure.

[0029] The radius length of the installation cylinder 240 is less than the radius length of the installation hole 190. The interval distance length of the six groups of installation cylinders 240 is equal to the interval distance length between the six groups of installation holes 190.

[0030] The outer side of the stabilizing ring 210 contacts the inner side of the clamping ring 180. The width of the stabilizing ring 210 is greater than that of the clamping ring 180, and the radius length of the stabilizing ring 210 is less than that of the mounting ring 200. During actual use, start the air extraction mechanism 150 and open the valve at the top of the feed pipe 140. The air extraction mechanism 150 operates to suck the dust particles diffused in the air inside the main body 100 of the mixing device into the collection box 110 through the air extraction pipe and the feed pipe 140. Under the action of the air extraction mechanism 150, the dust particles move downward inside the collection box 110. When the dust particles pass through the collection cloth bag 220, since the diameter length of the dust particles is less than the diameter length of the mesh holes on the surface of the collection cloth bag 220, the dust particles are intercepted and collected inside the collection cloth bag 220 through the collection cloth bag 220. Then, through the collection of the dust particles by the collection cloth bag 220, the recovery of the dust particles is realized, and at the same time, the waste of the dust particles is avoided.

[0031] A handle one is provided on the top of the top cover 120. The box door 130 is hinged to the left side of the front of the collection box 110 through a hinge post. A handle two is installed on the right side of the front of the box door 130. A valve is provided at the top of the feed pipe 140. The top of the air extraction mechanism 150 is connected to the bottom of the collection box 110 through an air extraction pipe. During actual use, hold the handle one and open the top cover 120 upward. Then, use tools such as hooks to insert two groups of hooks into the collection box 110, so that the two groups of hooks respectively hook the inner sides of the two groups of handles 230, and then pull upward to make the six groups of mounting cylinders 240 disengage from the six groups of mounting holes 190 upward, and at the same time make the stabilizing ring 210 disengage from the clamping ring 180, so as to take out the collection mechanism 160. Pour the dust particles in the collection cloth bag 220 into an external dust recovery mechanism for treatment, so as to recycle the dust particles. Then, the collection mechanism 160 can be maintained to ensure the collection effect of the collection mechanism 160. The final effect is to facilitate the recycling of dust particles, prevent resource waste, and at the same time facilitate the maintenance of the collection mechanism 160.

The six groups of installation cylinders 240 are fitted and connected with the six groups of installation holes 190. At the same time, the inner side of the clamping ring 180 is in contact with and closely fits the outer side of the stabilizing ring 210. Since the material of the clamping ring 180 is rubber, it has a stabilizing clamping effect on the stabilizing ring 210 and also has a sealing effect. Start the air extraction mechanism 150 and open the valve at the top of the feed pipe 140. The air extraction mechanism 150 works to suck the dust particles diffused in the air inside the mixing device main body 100 into the collection box 110 through the air extraction pipe and the feed pipe 140. Under the action of the air extraction mechanism 150, the dust particles move downward inside the collection box 110. When the dust particles pass through the collection cloth bag 220, since the diameter length of the dust particles is smaller than the diameter length of the surface mesh holes of the collection cloth bag 220, the dust particles are intercepted and collected inside the collection cloth bag 220 through the collection cloth bag 220. Then, through the collection of the dust particles by the collection cloth bag 220, the recovery of the dust particles is realized, and at the same time, the waste of the dust particles is avoided.

[0033] Embodiment 2: Please refer to Figure 3 and Figure 4 , after the premixing work of the castable is completed, hold the first handle and open the top cover 120 upward. Then, use tools such as hooks to insert two hooks into the collection box 110, so that the two hooks respectively hook the inner sides of the two handle grips 230, and then pull upward to make the six groups of installation cylinders 240 disengage from the six groups of installation holes 190 upward, and at the same time make the stabilizing ring 210 disengage from the clamping ring 180, so as to take out the collection mechanism 160. Pour the dust particles in the collection cloth bag 220 into an external dust recovery mechanism for treatment, so as to recycle and reuse the dust particles. Then, the collection mechanism 160 can be maintained to ensure the collection effect of the collection mechanism 160. The final effect is to facilitate the recycling and reuse of dust particles, prevent resource waste, and at the same time facilitate the maintenance of the collection mechanism 160.
