Description

Technical Field

[0001] The embodiments of the present utility model belong to the technical field of solid particle feeding, and more specifically, relate to a solid particle feeding gun integrated with a switch. Background Art

[0002] A solid particle feeding gun is a device used to automatically transport solid particle materials from a container to a processing device or a feed bin. It mainly uses the airflow generated by compressed air or other gases to carry and transport solid particles, and the conveying speed and conveying volume of the materials can be controlled by adjusting the air pressure and air flow rate. Such devices are widely used in various industrial production environments, such as the plastic processing, pharmaceutical, and food processing industries.

[0003] The traditional feeding gun has a simple pipeline structure, and compressed gas is introduced into it. The materials in the material bin are transported to a set position by the action of the compressed gas. When in use, the operator hangs the feeding gun on the feeding port, opens the valve, and the materials are fed through the feeding gun under the push of the compressed gas. When the bin is full, the valve is closed to stop the feeding. In order to reduce the dust flying generated during the feeding process and improve the working environment, a dust-free feeding gun has emerged. For example, a Chinese patent with the document number CN205838030U discloses a dust-free feeding gun, which includes a feeding pipe and a gun body. The gun body includes a containing cavity. The feeding port provided in the upper part of the containing cavity is connected to a material container for containing granular materials through a feeding pipe and a feeding valve. The lower part of the gun body is provided with a discharge port. One end of the feeding pipe is inserted into the containing cavity from the feeding port, and the other end of the feeding pipe is provided with a feeding valve. A dust removal port is provided on the gun body, and the dust removal port of the gun body is connected to a negative pressure system through a dust removal pipe. An air intake regulating device is provided at the balanced air intake port of the gun body.

[0004] The dust-free feeding gun of the above patent can use the dust removal pipe to suck away the dust generated during the feeding process through negative pressure, realizing a dust-free feeding process and greatly improving the working environment. However, it still cannot solve some problems faced during the use of traditional solid particle feeding guns: (1) The feeding gun usually uses a valve to control the switch. Due to the impact of solid particles, fine particles are easily ground by the valve and flow into the valve body gap, resulting in poor switching of the feeding gun and affecting its service life; (2) The traditional ball valve type feeding gun is made of an integral casting. When the valve is damaged and needs to be maintained, the whole gun must be replaced, resulting in high maintenance costs; (3) The dust removal component is located near the discharge port and is fixed in position, which easily causes the dust removal component to be blocked by solid particles, increasing the maintenance cost and affecting the feeding.
