Material bin with bridge breaking devices

Abstract

The invention discloses a material bin with bridge breaking devices. The material bin comprises a base of a frame structure, wherein a bin body is arranged on the base, the bin body comprises at leastone slope bottom face, a discharging opening is formed between the bottoms of the slope bottom faces, and one knife gate valve is transversely arranged below the discharging opening; and the materialbin further comprises at least one bridge breaking device arranged along the slope bottom surface, each bridge breaking device comprises a sliding frame which is arranged along the corresponding slope bottom surface and is opposite to the discharging opening and a first driving device which is connected with the corresponding sliding frame through one push rod and drives the corresponding slidingframe to do reciprocating motion along the corresponding slope bottom surface. The material bin has the following beneficial effects that 1), the purpose of bridge breaking is achieved through front-back movement of the sliding frames, so that it is ensured that materials are smoothly discharged; 2), a valve plate is limited through guide pressing blocks arranged above the valve plate, so that the sealing performance of the valve plate is improved; and 3), material discharging and the discharging amount can be accurately controlled through a spiral conveyor with two sets of spiral blades different in spiral direction.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a material bin with a bridge breaking device. Background technique [0002] At present, in order to facilitate storage, save space, protect the environment, and save energy, some enterprises put the produced or needed materials into airtight silos in various ways for storage. After a period of storage and collection, it is discharged from the silo when needed for subsequent processing. For liquids or granular solids with good fluidity and no compaction, there is no problem regardless of the storage volume and the size of the discharge port. However, for solid materials with poor fluidity, easy hardening, and easy bridging, it is very difficult to discharge materials due to their characteristics. Therefore, the storage bin volume is generally made smaller and the discharge port is made larger. The disadvantages of this type of silo are: 1. The volume is small, and it cannot...

Problems solved by technology

The disadvantages of this type of silo are: 1. The volume is small, and it cannot be stored in large quantities at one time; 2. The discharge port is large, and the discharge speed is fast and difficult to control; the discharge area is large, it is easy to scatter and is not easy to be sent into the container of the next process equipment; 3. Large discharge port, not easy to seal

Because the material accumulates on the support bar, the valve plate will deviate from the support bar, resulting in deformation of the valve plate, movement jamming and failure; in addition, the seal will not be tight, resulting in material leakage, waste and pollution of the environment
