Equipment and method for conveying solid materials through vacuum draught fan positive and negative pressure

Abstract

The invention provides an equipment and method for transporting solid materials by using the positive and negative pressure of a vacuum fan, which belongs to the technical field of industrial equipment. The equipment and method realize the transportation of solid materials by using the negative pressure function of the vacuum fan (2), and at the same time The air with a certain pressure at the outlet of the vacuum fan (2) is stored in the air storage tank (5), and the air with a certain pressure in the air storage tank (5) is used to purge the discharge pipe of the small hopper (14) when feeding , to ensure the smooth delivery of solid materials. The equipment and method ensure smooth feeding of solid materials, solve the problem that when solid materials are added to a container containing high-temperature liquid, the steam in the container overflows, condenses on the pipeline, sticks solid materials, and blocks the pipeline. Improve the working environment, save energy and reduce production costs.

Description

technical field [0001] The invention belongs to the technical field of industrial equipment, and in particular relates to equipment and a method for conveying solid materials by positive and negative pressure of a vacuum blower. technical background [0002] Reverse osmosis technology is the most economical and applicable water treatment technology with mature production technology and excellent treatment effect. It has been widely used in various fields such as sewage treatment, seawater desalination, and household drinking water treatment. In the reverse osmosis production line, the function of automatically conveying solid materials is usually realized by a vacuum feeder. First, the weighed solid materials are put into the hopper, and then the air in the small hopper is drawn by a vacuum fan to form a negative pressure. The hopper is sucked into the small hopper, and finally, the discharge valve is opened, and the solid material is added into the container. [0003] Howe...

AI Technical Summary

Problems solved by technology

[0003] However, this technology currently has the following problems: 1. The size of the feeding port is small, which is easy to cause the material to arch and make the feeding difficult; 2. There is a high-temperature liquid of about 70 degrees in the container. When feeding, the steam overflows and condenses on the pipe and On the hopper, solid materials are bonded, and then blockage occurs; 3. When feeding, the steam overflows into the room through the feeding port, which may be harmful to the human body and pose a safety hazard; 4. The discharge port of the vacuum fan has a certain pressure energy and cannot be used. use, waste energy
