[0002] Vacuum batching tanks are widely used in the pharmaceutical, bioengineering, food, beverage, fruit wine, condiment, fine chemical, oil and other industries. The homogenous batching of the vacuum batching tank can effectively reduce the bubbles generated in the batching process. As shown in a vacuum homogenizing batching tank (public announcement number CN211800541U) disclosed on the China Patent Network, when such a device is in use, the air in the batching tank is extracted by a vacuum pump to make the batching tank in a vacuum state, and then the material and water are added to the batching tank through the feeding device, and the material and water in the batching tank are crushed and stirred by the crushing and stirring device to make the material fully crushed and mixed. Subsequently, the inner wall of the batching tank is cleaned by the cleaning device to prevent the residue from sticking to the batching tank and affecting the later batching.

[0003] However, there are still some shortcomings in the above-mentioned public patents and the vacuum homogenizing batching tanks adopted in the existing market: the existing method of using a combination of crushing blades and stirring blades to homogenize and stir the materials in the vacuum tank can only perform homogenizing and stirring work in the horizontal layer, and cannot effectively stir and mix the materials in the upper and lower layers, resulting in poor homogenizing and mixing efficiency of the materials. To this end, those skilled in the art provide a vacuum homogenizing batching tank to solve the problems raised in the above background technology. Utility Model Content

[0026] Please refer to Figure 1-4As shown, a vacuum homogenizing batching tank comprises a vacuum tank 1, a feed valve 2 is installed on the front side of the upper end of the tank body of the vacuum tank 1, a vacuum valve 4 is installed on the rear side of the upper end of the tank body of the vacuum tank 1, and a discharge valve 3 is installed on the bottom of the vacuum tank 1. Materials are added into the vacuum tank 1 through the feed valve 2 for homogenous mixing, and the vacuum tank 1 is evacuated through the vacuum valve 4 to avoid the presence of air causing bubbles and the like during the homogenous mixing of materials, and the homogenously mixed materials are subsequently discharged through the discharge valve 3.

[0027] A brake motor 5 driving the brake shaft 14 is installed at the upper end of the tank body of the vacuum tank 1. By controlling the operation of the brake motor 5 as a driving source, the brake shaft 14 is driven to rotate, and then the corresponding components are driven to operate, so as to homogenize and stir the materials in the vacuum tank 1.

[0028] A feeding tube 6 is installed in the middle of the tank body of the vacuum tank 1, and a brake shaft 14 is rotatably connected to the middle of the pipeline of the feeding tube 6, and a spiral auger 15 fitting with the feeding tube 6 is sleeved on the outer side of the shaft of the brake shaft 14, and a feeding pipe opening 12 is opened at the bottom end of the pipeline of the feeding tube 6, and a discharge pipe opening 13 is opened at the top end of the pipeline of the feeding tube 6. When the brake shaft 14 rotates, it drives the spiral auger 15 to rotate, and the material at the bottom of the vacuum tank 1 is pushed up along the feeding tube 6 through the feeding pipe opening 12, and discharged through the discharge pipe opening 13, so that the upper and lower layers of materials are circulated and mixed to ensure the comprehensiveness and uniformity of the homogeneous mixing of the materials.

[0029] The outer ring of the pipe of the feeding barrel 6 is provided with multiple groups of rotating sleeves 9, and the outer side of the ring of each group of rotating sleeves 9 is provided with a stirring impeller 10, the top of the shaft rod of the brake shaft 14 is provided with an arm frame 7, and the bracket edge of the arm frame 7 is provided with multiple groups of transmission shafts 8 that penetrate the rotating sleeves 9 along its circumferential direction, and the multiple groups of stirring impellers 10 are arranged at equal intervals. When the brake shaft 14 rotates, the combination of the arm frame 7 and the transmission shaft 8 rotates, which in turn drives the rotating sleeves 9 to rotate, and pushes the stirring impeller 10 to rotate, so as to perform synchronous horizontal homogeneous stirring on the upside-down mixed materials, thereby improving the multi-directional homogeneous mixing of the materials.

[0030] A scraper mechanism 11 that fits the wall of the vacuum tank 1 is sleeved on the outer side of the shaft of one group of transmission shafts 8, and the scraper mechanism 11 includes a compression frame 111, and a fixed bracket 112 fixedly connected to the transmission shaft 8 is installed on the back plate of the compression frame 111, and a compression support plate 115 is slidably connected inside the compression frame 111, and a cleaning scraper 116 that fits the wall of the vacuum tank 1 is arranged in the middle of the plate frame of the compression support plate 115. When the transmission shaft 8 rotates, the scraper mechanism 11 is driven to rotate synchronously, and the material on the wall of the vacuum tank 1 is scraped and cleaned by the cyclic scraping of the cleaning scraper 116 in the scraper mechanism 11, so as to prevent the material from adhering to the wall of the vacuum tank 1.

[0031] The back plate of the compression support plate 115 is arranged with multiple groups of compression guide rods 113 that pass through the compression frame 111, and the outer side of the support rod of each group of compression guide rods 113 is sleeved with a compression spring 114 that presses against the compression frame 111. During the scraping and cleaning process of the vacuum tank 1 wall, based on the elastic force combination of the compression spring 114 and the compression guide rod 113, the compression support plate 115 and the compression frame 111 are elastically pressed against each other, so that the cleaning scraper 116 elastically scrapes and cleans the tank wall of the vacuum tank 1.

[0032] The working principle of the utility model is as follows: when using a vacuum homogenizing batching tank to homogenize and mix materials, firstly, the materials are added into the vacuum tank 1 through the feed valve 2, and then the vacuum tank 1 is evacuated based on the vacuum valve 4 to avoid the presence of air causing bubbles to appear during the homogenization and mixing of materials;

[0033] The brake motor 5 is further controlled to work as a driving source, driving the brake shaft 14 to rotate. While the brake shaft 14 rotates, on the one hand, it drives the spiral auger 15 to rotate, and pushes the material at the bottom of the vacuum tank 1 along the feeding tube 6 through the feeding pipe opening 12, and discharges it through the discharge pipe opening 13, so that the upper and lower layers of materials are circulated and mixed. On the other hand, it drives the combined rotation of the arm frame 7 and the transmission shaft 8, and then drives the rotating shaft sleeve 9 to rotate, and drives the stirring impeller 10 to rotate, so that the materials that are turned upside down and mixed are synchronously horizontally homogenized, so that the materials are fully homogenized and mixed up and down and horizontally;

[0034] When the transmission shaft 8 rotates, the scraper mechanism 11 is driven to rotate synchronously, and the material on the wall of the vacuum tank 1 is scraped and cleaned by the cyclic scraping of the cleaning scraper 116 in the scraper mechanism 11, so as to prevent the material from adhering to the wall of the vacuum tank 1;

[0035] After the materials are homogenized and mixed, the discharge valve 3 is opened to discharge the materials in a circulation manner. The spiral auger 15 is synchronously controlled to rotate in the opposite direction to push out the residual materials in the feeding barrel 6 in the opposite direction. The bottom materials can also be stirred in a circulation manner to facilitate the unloading of the materials and avoid blockage.
