Abstract
Description
Technical Field
[0001] The utility model belongs to pharmaceutical processing equipment, and particularly relates to a vacuum automatic feeding device supporting a white sugar crusher. Background Art
[0002] As a common food raw material and pharmaceutical excipient, white sugar is refined from molasses squeezed from sugarcane or sugar beet through a series of processes. It has a white appearance, clean texture, high sweetness, and the sugar components it contains are one of the important nutritional sources for the human body, occupying an indispensable position in people's daily lives. It can not only add sweetness to food but also has various key applications in the field of pharmaceutical production, specifically reflected in improving the taste of drugs, acting as a shaping agent, stabilizing drug properties, promoting drug dissolution, and regulating drug efficacy, etc.
[0003] In the process of pharmaceutical production, to meet the process requirements of different pharmaceutical preparations, white sugar usually needs to be pulverized before use. By operating a crusher on white sugar, the particle size of white sugar can be gradually reduced until it reaches the particle size standard required by a specific process. Subsequently, the pulverized white sugar will be transported to subsequent relevant workshops and participate in the subsequent links of pharmaceutical production.
[0004] However, in the relevant technical practice, taking the white sugar crusher involved in the utility model patent with the publication number CN221638404U as an example, the current feeding method of the white sugar crusher still mainly relies on manual operation. In the case of a large-scale pharmaceutical production, for example, when the average daily consumption of white sugar reaches 300KG, the manual feeding method has obvious drawbacks. On the one hand, the labor intensity of manual feeding is extremely high, and long-term operation is likely to cause fatigue of workers, thereby affecting the feeding efficiency; on the other hand, the speed and accuracy of manual feeding are difficult to guarantee, which may have an adverse impact on the subsequent pulverization process and the stability and efficiency of the entire pharmaceutical production process. Therefore, aiming at the problem of high labor intensity of manual feeding in the existing white sugar crusher technology, it is necessary to explore a more efficient and convenient feeding method to improve the overall efficiency and quality of white sugar pulverization and subsequent pharmaceutical production.
[0005] The above information disclosed in the background art part is only used to strengthen the understanding of the technology described in this article. Therefore, the background art may contain certain information that is not known prior art to those skilled in the art. Content of the Utility Model

[0026] See Figure 2 The mounting frame 302 includes a rectangular frame 3021 composed of steel pipes. A support plate 3022 is installed inside the rectangular frame 3021, and a through groove 3023 is provided in the middle of the support plate 3022. The hopper 4 is fixed above the through groove 3023 of the support plate 3022. The rectangular frame 3021 is welded from stainless steel round pipes, and a reinforcing rib 3024 is provided between the rectangular frame 3021 and the outer column. The reinforcing rib 3024 is made of 5 mm thick stainless steel plate, is triangular in shape, and is welded to the outer column on one side and to the rectangular frame 3021 on the other side, enhancing the stability of the entire support structure 3. The support plate 3022 is made of 8 mm thick stainless steel plate, and its dimensions match the internal dimensions of the rectangular frame 3021. The through groove 3023 in the middle of the support plate 3022 is a circle with a diameter of 20 cm, used for the passage of the bottom discharge port 10 of the hopper 4.
[0027] The hopper 4 is a cylindrical structure made of stainless steel. A filter box 13 is located on top of the hopper 4 and is connected to the hopper body. The vacuum pump 6 is connected to the filter box via a suction pipe 5. The filter box 13 is also made of stainless steel. Inside the filter box is a filter element made of high-efficiency filter material, which effectively filters fine particles in the air and prevents dust from entering the vacuum pump 6. The filter element is removable for easy cleaning or replacement.
[0028] The hopper 4 has an interface on its side, which connects to the vacuum pump 6 via a suction pipe 5. The suction pipe 5 is a pressure-resistant hose with a diameter of 25 mm, and its length is determined according to the actual installation location, typically 150-200 cm. The vacuum pump 6 is an industrial-grade vacuum pump with a power of 1.5 kW and a maximum vacuum degree of -0.08 MPa, capable of generating sufficient negative pressure for material suction.
[0029] The top of the hopper 4 has a feed inlet, which connects to the storage tank 8 via a suction pipe 7. The suction pipe 7 is a 40mm diameter wear-resistant flexible hose, and its length is determined based on the actual operating environment, typically 200-300cm. A suction gun 9, made of stainless steel and 30cm long, is installed at the end of the suction pipe 7. The suction gun has an opening at the front end with an anti-clogging mesh to prevent large pieces of material from clogging the suction pipe 7. The storage tank 8 is a standard white sugar storage container, with its volume determined based on actual production needs.
[0030] The bottom of the hopper 4 is equipped with a discharge port 10, which has a diameter of 15 cm. A rotary valve 11 is installed at the discharge port 10.

[0033] The working process of this sugar grinder equipped with a vacuum automatic feeding device is as follows:
[0034] First, install the main body 1 of the crusher on the workbench 2, adjust the height of the support legs of the workbench 2 to make the crusher a suitable working height, and lock the support leg brake device to ensure the stability of the workbench 2.
[0035] Next, vacuum pump 6 is started. Vacuum pump 6 generates negative pressure inside silo 4 through suction pipe 5. The operator holds suction gun 9 and inserts it into the sugar in storage bucket 8. Under the action of negative pressure, the sugar is sucked into silo 4 through suction pipe 7. Upper level gauge 12 monitors the material height in silo 4. When the set height is reached, vacuum pump 6 is automatically stopped, completing the feeding process.
[0036] Then, rotate bracket 3 so that hopper 4 is directly above the feed inlet of the crusher. The rotation of bracket 3 is achieved by a rotary bearing between the inner and outer columns. The operator can manually rotate the outer column to adjust hopper 4 to the appropriate position.
[0037] Finally, open the rotary valve 11 to control the sugar to fall from the discharge port 10 of the hopper 4 into the feed port of the crusher. The level gauge 12 at the discharge port 10 monitors the discharge status. When the material in the hopper 4 is lower than the set value, the system will prompt that material needs to be added again. The opening degree of the rotary valve 11 can be adjusted according to the processing capacity of the crusher to ensure that the feeding speed matches the crushing speed.
[0038] This sugar pulverizer is equipped with a vacuum automatic feeding device, which automatically feeds sugar through vacuum suction, reducing the labor intensity of operators and improving production efficiency. The rotating design of the support 3 makes the position of the hopper 4 adjustable, facilitating feeding and unloading operations. The level gauge 12 ensures automated control of the feeding and unloading process, avoiding material overflow or insufficient supply. The filter box 13 and filter element protect the vacuum pump 6, extending the service life of the equipment. The movable support legs on the underside of the worktable 2 give the entire device good mobility, facilitating workplace adjustment and cleaning.
