Safety feeding system

Abstract

The invention discloses a safety feeding system. The safety feeding system comprises a feeding valve used for being fixed at the position, close to a port, of a feeding pipe. The feeding valve comprises a connecting plate arranged on the feeding pipe and a blocking piece hinged to the connecting plate. The blocking piece is used for opening and closing the port of the feeding pipe. The feeding valve comprises a locking piece for locking the blocking piece, the locking piece acts according to an electric signal about feeding allowing or an electric signal about feeding completion, and accordingly relative locking and locking releasing can be achieved for the blocking piece and the feeding pipe. According to the safety feeding system, when feeding is not needed, the blocking piece is used for blocking the port of the feeding pipe, and the situation that materials enter the feeding pipe without permission, mistaken feeding is caused, and the burdening performance is influenced is avoided;when feeding is needed, the locking piece acts, the locking relation between the blocking piece and the feeding pipe is released, the blocking piece is manually or mechanically driven to move, and the port of the feeding pipe is opened for feeding; and after feeding is finished, the blocking piece is manually or mechanically driven to move, the port of the feeding pipe is blocked, and then the blocking piece and the feeding pipe are locked through the locking piece.

Description

technical field [0001] The invention belongs to the technical field of safety feeding equipment, in particular to a safety feeding system. Background technique [0002] There are three kinds of dangers that inevitably exist during the use of the silo: overpressure, roof fall and lack of material. The so-called overpressure means that due to the positive pressure in the bin during the powder feeding process, the air is not discharged in time and the industry standard is exceeded; the roof fall means that there is no material level display during the powder feeding process, resulting in the material filling the bin body; lack of material means During the discharge of materials in the warehouse, there is no warning on the material level, which affects production. [0003] In the prior art, there is no protective measure for the port of the feeding pipe. In the prior art, the feeding process in the warehouse is as follows: the pipe joint on the tanker is manually connected to t...

Problems solved by technology

The so-called overpressure means that due to the positive pressure in the bin during the powder feeding process, the air is not discharged in time and the industry standard is exceeded; the roof fall means that there is no material level display during the powder feeding process, resulting in the material filling the bin body; lack of material means During the discharge of materials in the warehouse, there is no warning on the material level, which affects production

[0003] In the prior art, there is no protective measure for the port of the feeding pipe. In the prior art, the feeding process in the warehouse is as follows: the pipe joint on the tanker is manually connected to the port of the feeding pipe, and the powder is blown into or Press into the silo, when the powder reaches the maximum amount, stop feeding

[0004] In the prior art, debris is easy to drill into the feeding pipe through the port, causing the feeding pipe to be blocked, and because the feeding pipe is generally relatively long, it is troublesome to clean up and needs to be shut down, resulting in low production efficiency

[0005] And the loading workers must correctly find the position of the feeding tube that needs to be loaded before loading, and then load the material. When the worker is looking for the feeding tube to load, it is easy to load the wrong material, resulting in no need to load A roof fall accident occurred in the material silo, which seriously polluted the environment
