Problems solved by technology

The process is relatively simple, but there are several problems as follows: 1. Static electricity generated by friction between powder and mechanical parts, and potential explosion caused by static electricity; 2. Dust is suspended in the air at an appropriate concentration to form a dust cloud, which is easy to cause Dust explosion; 3. The problem of powder flying caused by direct feeding requires adding dust removal equipment to increase operating costs. At the same time, after the flying powder is sucked away by the dust removal equipment, it cannot be reused, resulting in waste of powder. Feiyang will also cause certain physical hazards to the operator; 4. Direct feeding is easy to cause agglomeration of materials, resulting in uneven mixing

Embodiment Construction

[0028] Such as figure 1 As shown, a powder feeding system includes a feeding device 1, a circulation pipeline 2 sealed with the discharge end of the feeding device 1,

[0029] The inner diameter of the upper part of the feeding device 1 gradually decreases, and when one end of the powder bag 3 is placed on the feeding device 1, the powder bag 3 is in close contact with the inner wall of the feeding device 1,

[0030] The lower part of the feeding device 1 is provided with a cutting knife 4, which is used to cut the end of the powder bag 3 into the feeding device.

[0031] When the cutting knife 4 cuts the powder bag 3, the powder falls into the circulation pipeline 2, and at the same time, the liquid in the circulation pipeline 2 flows, forming a negative pressure at the outlet of the feeding device 1, and further sucking the powder In the circulation pipeline, it can also effectively prevent the powder from flying.

[0032] The feeding device 1 can be divided into upper and...

Abstract

The present invention provides a powder material feeding system, including a feeding device and a circulation pipeline which is in sealing connection with the discharge end of the feeding device, the inside diameter of the upper part of the feeding device is gradually reduced, when one end of a powder material bag is on the feeding device, the inner wall of the powder material bag is in close contact with the inner wall of the feeding device, the lower part of the feeding device is provided with a cutting knife, the cutting knife is used to put the powder material bag into a cutting opening of one end of the feeding device. The beneficial effects are that: the powder material feeding system is simple in structure, prevents the powder material to fly upward, and a material is evenly mixed.

Description

technical field [0001] The invention relates to the field of liquid and powder mixing process equipment, in particular to a powder feeding system. Background technique [0002] In modern industrial production, putting solid powder into liquid is the most common production process in the pharmaceutical, food, chemical and cosmetic industries. The traditional feeding method mostly adopts the direct feeding method, that is, the material is directly added to the reaction tank through the gravity of the solid material itself, and the powder is mixed with the liquid by using a stirring device. The process is relatively simple, but there are several problems as follows: 1. Static electricity generated by friction between powder and mechanical parts, and potential explosion caused by static electricity; 2. Dust is suspended in the air at an appropriate concentration to form a dust cloud, which is easy to cause Dust explosion; 3. The problem of powder flying caused by direct feeding...
