Description

Technical Field

[0001] The utility model relates to the technical field of vacuum feeding, in particular to a vacuum feeding device for a mixer. Background Art

[0002] In the fields of food, medicine, chemical industry, etc., mixing is the most common process. Mixing equipment is needed to mix two or more materials evenly to meet the requirements of subsequent product processing technology. At present, the commonly used mixing equipment on the market mainly includes three-dimensional mixers, two-dimensional mixers, lifting mixers, spiral mixers and other mechanical mixing devices, as well as pulse airflow mixers and circulating airflow mixers. The materials of these mixers are generally fed by manual feeding, spiral feeding, gas positive pressure feeding and vacuum negative pressure extraction. Among them, the vacuum negative pressure extraction method has been widely used due to its low energy consumption, good airtightness and high extraction efficiency. However, at present, the vacuum feeder that uses the vacuum negative pressure extraction method has only a single extraction port. When multiple materials need to be fed at the same time, they can only be extracted one by one, which is inefficient and cannot achieve material pre-mixing, which prolongs the material mixing time and increases the operating cost of the mixing equipment.

[0003] In order to solve the above technical problems, the Chinese utility model patent with the authorization announcement number CN207076428U discloses a tangential vacuum feeding device for a mixer. The utility model connects a vacuum valve to the mixing tube and sets a double tangential feeding port on the tube wall of the mixing tube, so that the material can enter the mixing tube tangentially under vacuum conditions, and then perform centrifugal motion along the tube wall of the mixing tube. The material is dispersed and crossed during the rotation process, and the mutual movement realizes the pre-mixing of the material. Therefore, the use of this feeding device not only shortens the time of feeding the material into the mixer during mixing, but also realizes the pre-mixing during the material feeding process, shortens the mixing time required for the material in the mixer, improves the mixing efficiency, and reduces energy consumption;

[0004] Although the technical solution provided by the utility model solves the problem that some existing vacuum feeders have only a single feeding port, the material transported by the vacuum feeding device is generally powdered material, and a portion of the powdered material is often adsorbed on the inner wall of the storage tank after the transportation is completed. The above solution does not solve this problem well, which will cause waste of materials, increase costs, and is not convenient to use. Utility Model Content

[0005] The purpose of the utility model is to provide a vacuum feeding device for a mixer to solve the problems raised in the above background technology.

[0006] The present application embodiment adopts the following technical solutions:

[0007] A vacuum feeding device for a mixer comprises a storage tank, wherein the storage tank is connected to a vacuum feeding bin via a feeding hose, and the vacuum feeding bin is connected to a vortex air pump via a vacuum extraction pipe. A mounting seat which can be raised and lowered is arranged inside the storage tank, a deformable scraper ring is arranged on the outer side of the mounting seat, and a driving mechanism for driving the mounting seat to be raised and lowered is arranged on the top of the storage tank.

[0008] Beneficial effects:

[0009] The utility model provides a mounting seat which can be lifted up and down inside the storage tank. When it is necessary to scrape the material adsorbed on the inner wall of the storage tank, the mounting seat can be controlled to descend, so that the scraping ring in contact with the inner wall of the storage tank can be driven to descend synchronously, thereby scraping the material inside the storage tank and avoiding the waste of material.

[0012] Preferably, the mounting seat is circular, and four telescopic rods are fixedly mounted on the arc-shaped outer surface of the mounting seat. The four telescopic rods are evenly arranged in a ring shape with the center of the mounting seat as the center. One end of the telescopic rod is fixedly connected to the mounting seat, and the other end of the telescopic rod is fixedly connected to the inner wall of the scraper ring.

Through the matching setting between the connecting rod 12 and the lifting plate 13, the internal threaded column 11 can be limited to prevent the internal threaded column 11 from rotating with the threaded rod 10;

Four arc-shaped plates are fixedly mounted on the inner wall of the scraper ring 8.
