Description

Technical Field

[0001] The utility model belongs to the technical field of powder mixing devices, and in particular relates to a powder mixing device capable of preventing dust from spreading. Background Art

[0002] Powder generally refers to fine powder, such as powder for cosmetics, crushed powder, food made from starch, and finely divided solid raw materials for various industrial products. In the production and manufacturing process of various industries, powder raw materials account for a large proportion, and generally multiple powder raw materials need to be stirred and mixed with water or other liquid raw materials.

[0003] Chinese patent CN221182588U discloses a production mixing device, which relates to the field of coating production technology. The production mixing device includes a frame, a mixing tank is installed in the middle of the frame, a stirring shaft is provided in the mixing tank, the stirring shaft is directly connected to the output shaft of the stirring motor installed on the top of the mixing tank, stirring rods are installed on both sides of the stirring shaft, a scraper is installed at the bottom of the stirring shaft, a feed hopper is installed on one side of the upper part of the mixing tank, a baffle is installed in the feed hopper, a dust-proof component is installed at the bottom of the baffle, a discharge pipe is installed at the bottom of the mixing tank, and a discharge valve is installed on the discharge pipe.

[0004] When adding raw materials to the tank, the dust raised from the raw materials inside the tank can easily leak out of the feed port and pollute the surrounding air environment. Workers who inhale large amounts of dust can easily develop pneumoconiosis. In the above document, when the feeding stops, the dust prevention component will automatically pop up, blocking the feed channel, thereby preventing the dust inside the tank from being blown out. However, the descent of the dust prevention component requires the powder raw materials to press down the dust cover. The weight of powder raw materials is generally light. To press down the dust cover, a large amount of powder raw materials must be poured into the hopper. Excessive powder raw materials can easily overflow from the hopper. If the dust cover cannot be opened in time, dust will still fly out.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
