Description

Technical Field

[0001] This utility model belongs to the technical field of fireproof material processing equipment, and in particular, it is a mixing device for fireproof sealing materials. Background Technology

[0002] In the production process of fireproof sealing materials, it is necessary to mix various raw materials to ensure the uniformity and fireproof performance of the materials. The raw materials include lumpy materials (such as recycled waste fireproof materials and agglomerated mineral fillers), which need to be crushed to a suitable particle size (such as ≤2mm) before they can be evenly dispersed. The existing fireproof sealing material mixing equipment has a weak crushing and screening capacity. Unqualified batches due to particle size or impurities need to be re-crushed and screened, which increases energy consumption and time costs.

[0003] A search revealed Chinese patent document (authorization announcement number CN221514152U), which discloses a mixing device for water-based expandable fireproof material, relating to the field of fireproof material production technology. This invention utilizes the synchronous rotation between the bearing and the mixing shaft to provide support during shaft rotation. Simultaneously, under centrifugal force, the movable rod causes the movable block and rod to move outwards, allowing the scraper to adhere closely to the inner wall of the mixing drum during shaft rotation, effectively scraping off material adhering to the inner wall. The scraper's inclined design directs the scraped material towards the center of the mixing drum, facilitating thorough mixing of the fireproof material. While this device meets basic usage requirements, its crushing and screening capabilities are weak. Unqualified batches due to particle size or impurities require re-crushing and screening, increasing energy consumption and time costs. Utility Model Content

[0004] The purpose of this invention is to provide a mixing device for fireproof sealing materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stirring device for fireproof sealing materials, comprising a base for supporting the raw materials of the fireproof sealing materials, wherein a protective bucket for preventing the raw materials of the fireproof sealing materials from splashing is installed on the top of the base;

[0006] The protective barrel has a fixed frame welded to its vertical inner wall for support. A hollow column is welded to the end of the fixed frame. A spring is connected inside the hollow column. U-shaped grooves for movement are symmetrically arranged on the outer periphery of the hollow column. One end of the spring is connected to a movable frame. The end of the movable frame is slidably disposed inside the U-shaped groove. A grinding wheel for crushing raw materials for fireproof sealing materials is installed on the outer periphery of the movable frame.

[0007] Preferably, the protective barrel has a rotatable container inside, and the vertical inner wall of the container is equipped with a screening plate for screening raw materials for fireproof sealing materials.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 5 The mixing device for fireproof sealing material shown includes a base 1 for supporting the raw material of fireproof sealing material, and a protective bucket 108 for preventing the raw material of fireproof sealing material from splashing out is installed on the top of the base 1.

[0027] A fixed frame 305 for support is welded to the vertical inner wall of the protective barrel 108. A hollow column 3 is welded to the end of the fixed frame 305. A spring 302 is connected inside the hollow column 3. U-shaped grooves 301 for movement are symmetrically arranged on the outer periphery of the hollow column 3. One end of the spring 302 is connected to a movable frame 303. The end of the movable frame 303 is slidably disposed inside the U-shaped groove 301. A grinding wheel 304 for crushing fireproof sealing material raw materials is installed on the outer periphery of the movable frame 303. The rotating column 2 drives the screening plate 204 to rotate. The screening plate 204 and the fixed frame 305 rotate relative to each other. The grinding wheel 304 presses the material on the screening plate 204. The raw materials are crushed by cylindrical rollers with toothed or grooved surfaces, driven by a motor (500-1500 r / min). The relative rotation between these rollers and the screen plate 204 creates a combined squeezing, shearing, and grinding action on the raw materials. A spring 302 continuously squeezes a movable frame 303, which in turn drives the grinding wheel 304 to continuously squeeze the fireproof sealing material raw materials. The crushed raw materials are discharged through the screen plate 204 and the discharge pipe 109. The screen plate 204 is a perforated plate below the grinding wheel 304, with apertures designed according to the target particle size (e.g., 0.5-5 mm), serving both crushing support and screening functions. When the raw materials are squeezed into the screen holes by the grinding wheel 304, particles that meet the particle size requirements fall through the screen holes into the bottom of the protective barrel 108, while coarse particles remain on the screen plate for further crushing.

[0028] The protective barrel 108 has a rotating container 205 inside. The vertical inner wall of the container 205 is equipped with a screening plate 204 for screening the raw materials of fireproof sealing material. The bottom of the screening plate 204 is connected to a rotating column 2. A connecting frame 201 is installed on the outer periphery of the rotating column 2. Two spiral plates 202 for stirring the raw materials of fireproof sealing material are rotatably installed at the bottom of the connecting frame 201. A limiting plate 203 for preventing the spiral plates 202 from falling off is installed on the top of the spiral plates 202. The stirring blade 104 drives the rotating column 2 and the connecting frame 201 to rotate. The spiral plates 202 come into contact with the raw materials. The rotation of the spiral plates 202 increases the fluidity of the raw materials and improves the stirring efficiency.

[0029] A rotating shaft 103 is welded to the bottom of the rotating column 2. Two stirring blades 104 for stirring the raw materials of fireproof sealing material are installed on the outer periphery of the rotating shaft 103. A motor 102 is installed inside the base 1. The output shaft of the motor 102 is connected to the end of the rotating shaft 103 through a coupling. When the motor 102 is turned on, the motor 102 drives the rotating shaft 103 and the stirring blades 104 to rotate. The stirring blades 104 stir the raw materials at the bottom of the protective barrel 108.

[0030] The top of the protective barrel 108 is equipped with a feed cover 105 for the entry of fireproof sealing material raw materials. A locking frame 106 is installed on the top of the feed cover 105. The locking frame 106 mainly drives the sealing cover 107 to contact and seal with the feed cover 105. The sealing cover 107 is installed on the movable part of the locking frame 106. The fireproof sealing material raw materials are added from the feed cover 105 into the holding barrel 205. The raw materials that meet the size requirements enter the bottom of the protective barrel 108 through the holding barrel 205. The bottom of the base 1 is equipped with moving wheels 101 for movement. The bottom of the protective barrel 108 is connected to the discharge pipe 109 for the discharge of fireproof sealing material.

[0031] Working principle

[0032] The mixing device for fireproof sealing materials works by first adding the raw material into the holding tank 205 through the feed cover 105. Raw materials of the correct size enter the bottom of the protective tank 108 through the holding tank 205. The motor 102 is then turned on, driving the rotating shaft 103 and the stirring blade 104 to rotate. The stirring blade 104 stirs the raw material at the bottom of the protective tank 108. The stirring blade 104 also drives the rotating column 2 and the connecting frame 201 to rotate. The spiral plate 202 contacts the raw material and rotates, increasing the fluidity of the raw material and improving the mixing efficiency. The rotating column 2 drives the screening plate 204 to rotate, causing relative rotation between the screening plate 204 and the fixed frame 305. The grinding wheel 304 crushes the raw material on the screening plate 204. The spring 302 continuously presses the movable frame 303, which in turn drives the grinding wheel 304 to continuously crush the fireproof sealing material raw material. The crushed raw material is discharged through the screening plate 204 and the discharge pipe 109 for the next process.
