Description

Technical Field

[0001] This utility model relates to the field of mixing technology, and in particular to a dry mixing pot mixing device. Background Technology

[0002] Dry mixing pots are core equipment for mixing and processing powder and granular materials. They are used to achieve uniform mixing of various materials in a dry state through mechanical stirring, so as to meet the requirements of subsequent processing for the consistency of material composition. Dry mixing pots are widely used in the fields of food processing and building materials, and are usually set up in semi-enclosed workshops.

[0003] When it is necessary to mix multiple dry materials, a dry mixing pot agitator is required to achieve uniform mixing of these materials. Existing dry mixing pot agitators mostly use simple paddles to agitate dry materials, which creates dead zones in the mixing process. Material accumulation can easily form stagnant zones, preventing full participation in the circulating mixing process. Furthermore, the mixing efficiency of a single paddle is insufficient to meet the high-efficiency requirements of modern production. This leads to reduced production efficiency, decreased product quality, and shortened service life. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 5 An embodiment of this utility model provides a dry mixing pot stirring device, including a mixing tank 1. A support plate 3 is fixedly connected to the inner wall of the mixing tank 1. A motor 4 is fixedly connected to the top of the support plate 3. A first bevel gear 5 is fixedly connected to the output end of the motor 4. A second bevel gear 6 is meshed with the inner wall of the first bevel gear 5. A transmission shaft 7 is fixedly connected to the inner wall of the second bevel gear 6. A sun gear 8 is fixedly connected to the outer wall of the transmission shaft 7. Multiple planet gears 9 are meshed with the inner wall of the sun gear 8. A spiral impeller 10 is fixedly connected to the bottom of the planet gear 9. An internal gear ring 11 is meshed with the inner wall of the planet gear 9. A scraper 12 is fixedly connected to the outer wall of the internal gear ring 11. Multiple spiral blades 13 are fixedly connected to the lower part of the outer wall of the transmission shaft 7. A feeding mechanism 2 is connected to the inner wall of the mixing tank 1. The feeding mechanism 2 is used to transport and supply powder materials.

[0032] Specifically, a support plate 3 is fixedly connected to the inner wall of the mixing tank 1, providing an installation position for the motor 4. The motor 4 is fixedly installed on its top, outputting power. The inner walls of the first bevel gear 5 and the second bevel gear 6 mesh, forming a bevel gear transmission. The inner wall of the first bevel gear 5 is fixedly connected to the transmission shaft 7, and the outer wall of the transmission shaft 7 is fixedly connected to the sun gear 8. The sun gear 8, as the central gear of the planetary gear system, plays a key role in the transmission process. The inner wall of the sun gear 8 meshes with multiple planet gears 9, which are evenly distributed around the sun gear 8, forming a planetary gear set. The bottom of each planet gear 9 is fixedly connected to a spiral impeller 10. The spiral impeller 10 has a unique spiral shape, which can generate a strong stirring force when rotating, causing the material to form a complex flow path in the mixing tank 1, thereby achieving full mixing of the material. When the transmission shaft 7 drives the sun gear 8 to rotate, the sun gear 8 drives the planet gears 9 through meshing with them. The planetary gear 9 rotates on its own axis and revolves around the sun gear 8. This combination of rotation and revolution allows the spiral impeller 10 to perform all-round and multi-layered mixing within the mixing tank 1, greatly improving mixing efficiency and uniformity. The inner wall of the planetary gear 9 is also meshed with an internal gear ring 11, which is fixed to the inner wall of the mixing tank 1, providing a track for the movement of the planetary gear 9. The scraper 12 can promptly scrape off the attached materials, preventing them from accumulating on the tank wall and forming hard lumps, ensuring the cleanliness of the inner wall of the mixing tank 1. It also improves the utilization rate of materials and the mixing effect. Several spiral blades 13 are fixedly connected to the lower part of the outer wall of the drive shaft 7. These spiral blades 13 are installed at a certain angle. When they rotate under the drive of the drive shaft 7, they can generate an upward thrust, conveying the materials at the bottom of the mixing tank 1 upward. The rotation of the spiral blades 13 can also further stir and tumble the materials, enabling the materials to be fully mixed in the vertical direction as well.

[0033] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4 The feeding mechanism 2 includes a conveying pipe 201. The bottom end of the conveying pipe 201 is connected to the inner wall of the mixing tank 1. The top end of the conveying pipe 201 is connected to a valve 202.

[0034] Specifically, the conveying pipe 201 is a key component in the feeding mechanism 2 that connects the mixing tank 1 and the valve 202. The valve 202 is installed at the top of the conveying pipe 201 and is used to control the entry of powder material into the mixing tank 1. When the valve 202 is open, the powder material enters the conveying pipe 201 under the action of gravity. The hopper 203 is located at the top of the valve 202 and is in close communication with the valve 202. One end of the feeding pipe 204 is connected to the inner wall of the hopper 203, and the other end is connected to the vacuum pump 205. It is an important channel for extracting powder material from the storage bin 206 and conveying it to the hopper 203. The vacuum pump 205 is the power core of the entire feeding mechanism 2. When the vacuum pump 205... Upon startup, a negative pressure environment is created within the feed pipe 204 and the storage silo 206, causing the powder material in the storage silo 206 to be drawn into the feed pipe 204 under atmospheric pressure. The storage silo 206 is the main container in the feeding mechanism 2 used to store a large amount of powder material. A motor 207 is fixedly connected to the top of the storage silo 206. The motor 207 is the power source for driving the stirring device. A transmission rod 208 is fixedly connected to the output end of the motor 207. The transmission rod 208 extends vertically into the storage silo 206. Multiple stirring blades 209 are fixedly connected to the outer wall of the transmission rod 208, which can effectively break up clumps in the material, keeping the material in a loose state for easy extraction and conveying.

The controller 24 is electrically connected to the vacuum pump 205, the motor 207 and the motor 4 respectively.

[0038] Specifically, the inner wall of the mixing tank 1 is provided with a discharge port 20 to pour out the mixed material, and the outer wall of the discharge port 20 is threaded with a sealing cap 21, which can be closed during the mixing process to prevent material leakage from affecting the mixing work. The outer wall of the storage bin 206 is fixedly connected with a scale 22, which can be used to observe the remaining material in the storage bin 206.

Multiple planetary gears 9 are meshed through the inner wall of the sun gear 8. The spiral impeller 10 fixedly connected to the bottom stirs and mixes the mixture simultaneously through the guidance of the spirally rising blades and the assistance of the small blades. At the same time, the sun gear 8 drives the planetary gears 9 to revolve around the sun, and the planetary gears 9 also rotate on their own axes due to their own characteristics. The combination of these two processes achieves thorough stirring in the mixing tank 1. Furthermore, the inner wall of the planetary gear 9 is meshed with the internal gear ring 11, and the outer wall of the planetary gear 9 is fixedly connected with the scraper 12, which is close to the inner wall of the mixing tank 1.

The feeding mechanism 2 is used to transport and supply powder materials to achieve sealed transmission of powder materials and prevent leakage.

[0040] The bottom end of the conveying pipe 201 is connected to the inner wall of the mixing tank 1 and is used to convey the powder into the mixing tank 1. The vacuum pump 205 is started to extract the powder stored in the storage bin 206 connected to the bottom end through the connected feeding pipe 204 and transfer it to the hopper bin 203. When the required amount is reached, the valve 202 connected to the bottom end is opened to allow the powder to be conveyed into the mixing tank 1 through the conveying pipe 201. The motor 207 fixedly connected to the top of the storage bin 206 is started and drives the fixedly connected transmission rod 208.
