Description

Technical Field

[0001] The utility model relates to the technical field of double-helix cone mixers, in particular to a double-helix cone mixer for lubricant production. Background Art

[0002] Double helix conical mixer is a kind of mixing equipment widely used in pharmaceutical, food, chemical, pesticide, feed, petroleum, metallurgy and mining, building materials industry, coating and other industries. In the production process of lubricant, it can quickly and evenly mix various powder materials to ensure product quality. The equipment adopts cantilever double helix shaft design without bottom bearing, which eliminates the failure caused by powder seepage of bottom bearing. At the same time, the double helix is ​​arranged asymmetrically, one large and one small, which expands the stirring range and makes it more suitable for mixing materials with different specific gravity and special mixing ratio.

[0003] The existing double-helix conical mixer, such as the double-helix conical mixer disclosed in publication number CN221182474U, although the turbulent screw can further strengthen the convection in the middle part, making the mixing more uniform during veterinary drug processing, and can effectively solve the problem of uneven mixing of traditional powders, but this double-helix conical mixer is inconvenient to discharge the sticky and residual materials on the inner wall of the double-helix conical mixer during direct discharge. For this reason, we propose a double-helix conical mixer for lubricant production. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0022] A double-helix cone mixer for lubricant production provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] Combination Figure 1-3 As shown, the utility model provides a double-helix cone mixer for lubricant production, comprising: a mixer body 100, a material discharge assembly 200; the mixer body 100 comprises a driving motor 101 fixedly mounted on the top thereof, a driving frame 102 driven by the driving motor 101 in the mixer body 100, spiral stirring rods 103 mounted on both sides of the driving frame 102, and a material discharge port 104 and a material feed port 105 fixedly mounted on the bottom and the top thereof respectively; the material discharge assembly 200 comprises a fixed cylinder 201 fixedly mounted at the lower end of the center of the driving frame 102, a slide groove 202 opened in the center of the fixed cylinder 201, a screw nut 203 movably matched and mounted in the slide groove 202, a connecting column 204 fixedly mounted on one side of the screw nut 203, A scraper 205 is fixedly installed on the outside of the connecting column 204, an opening 206 is provided in the connecting column 204, and a screw 207 is movably installed in the screw nut 203 and the opening 206. A micro motor 208 is also fixedly installed on one side of the connecting column 204 for driving the screw 207. Binding grooves 209 are also provided on both sides of the slide groove 202 in the connecting column 204. Binding blocks 210 are also fixedly installed on both sides of the outer end of the screw nut 203, and the binding blocks 210 on both sides are movably matched and installed in the binding grooves 209 on both sides. A protective cover 211 is also movably installed on the outer end of the micro motor 208, and the protective cover 211 is fixed to the outside of the connecting column 204. The fixed cylinder 201, the slide groove 202 and the connecting column 204 are all cylindrical structures.

[0025] Specifically, the double-helix conical mixer is a mixing equipment widely used in the pharmaceutical, food, chemical, pesticide, feed, petroleum, metallurgy and mining, building materials industry, coating and other industries. In the lubricant production process, it can quickly and evenly mix various powder materials to ensure product quality. When the lubricant after mixing and stirring inside the mixer body 100 is discharged, the micro motor 208 in the protective cover 211 can drive the scraper 205 on the outside of the fixed cylinder 201 to move and fit to the inner wall of the mixer body 100 during material discharge, so that the drive motor 101 at the upper end of the mixer body 100 drives the drive frame 102 to reduce speed, so as to rotate the scraper 205 fitted on the inner wall of the mixer body 100. Thereby, the lubricant adhering to the upper end of the inner wall of the mixer body 100 can be scraped off during the discharge, so as to ensure that there is less residue in the direct discharge of the mixer body 100, so as to improve its practicality and convenience in the discharge. At the same time, the protective cover 211 installed on the outer end of the micro motor 208 on the upper part of the fixed cylinder 201 can also provide safety protection for the micro motor 208 inside the mixer body 100 to ensure its service life. The restraining blocks 210 on both sides of the lead screw nut 203 in the fixed cylinder 201 are restrained in the restraining grooves 209 on both sides, which are mainly used to ensure the stability of the scraper 205 during driving. At the same time, the small-sized scraper 205 not in use can also be retracted and moved to the middle of the mixer body 100 to avoid affecting the mixing and stirring.

[0026] The working principle and use process of this utility model:

[0027] After the lubricant in the mixer body 100 is mixed and stirred, the discharge port 104 at the bottom can be opened to discharge the lubricant. When the lubricant is discharged, the micro motor 208 at the upper end of the fixed cylinder 201 can be started first. After the micro motor 208 is started, the screw rod 207 in the fixed cylinder 201 is driven to rotate. After the screw rod 207 rotates, the screw nut 203 and the connecting column 204 in the fixed cylinder 201 are driven to move outward, so that the scraper 205 at the outer end of the connecting column 204 is moved and attached to the mixer body 100 during the outward movement of the screw nut 203 and the connecting column 204. At the inner wall of the mixer body 100, after the scraper 205 is attached to the inner wall of the mixer body 100, the drive motor 101 on the top of the mixer body 100 can be started. When the drive motor 101 drives the drive frame 102 and the spiral stirring rod 103 at the bottom to rotate slowly, the scraper 205 adjusted to fit inside the mixer body 100 will also be driven to rotate, so that during the direct discharge of the lubricant in the mixer body 100, the residual and sticky parts of the material on the inner wall of the mixer body 100 are scraped off to ensure less residue in the direct discharge of the mixer body 100.

[0028] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
