Raw material grinding device with dust collection and recovery functions for mortar production

Abstract

The invention discloses a raw material grinding device with dust collection and recovery functions for mortar production. The raw material grinding device comprises a smashing shell, a dust collectionmechanism, a vibration separation mechanism, a power mechanism, a support, a box body and a lifting mechanism, wherein the left side and the middle part of the smashing shell are fixedly connected with the right side of the dust collection mechanism, the bottom of the smashing shell is fixedly connected with the left side of the top of the box body, the right side of the top of the box body is fixedly connected with the bottom of the lifting mechanism, and the middle part of the interior of the box body is fixedly connected with the front side and the rear side of the vibration separation mechanism. According to the raw material grinding device with the dust collection and recovery functions for mortar production, after raw materials are smashed through a first smashing roller and a second smashing roller, a large amount of dust is generated by the smashing shell falling into the box body, suction force is generated through the rotation of conveying blades, the generated dust is sucked into a dust collection annular pipe through a top washing pipe and a bottom suction pipe, then the sucked dust is conveyed into the box body through a first conveying pipe and a second conveying pipe, and then the dust is discharged out of the box body through a discharging groove in a centralized mode, so that the generated dust can be effectively treated.

Description

technical field [0001] The invention relates to the technical field of mortar production, in particular to a raw material grinding device for mortar production with the function of dust collection and recovery. Background technique [0002] According to the composition of the material, mortar can be divided into: ①lime mortar. It is made of lime paste, sand and water in a certain ratio, and is generally used for masonry and plastering layers that do not require high strength and are not subject to moisture; ②Cement mortar. It is made of cement, sand and water according to a certain ratio, and is generally used for masonry, walls or floors in humid environments or in water; ③Mixed mortar. Add appropriate admixtures such as fly ash, diatomaceous earth, etc. to cement or lime mortar to save the amount of cement or lime and improve the workability of the mortar. Commonly used mixed mortars include cement lime mortar, cement clay mortar and lime clay mortar. [0003] When mixi...

AI Technical Summary

Problems solved by technology

[0003] When mixing mortar, the raw materials need to be ground into fine powder, otherwise it is not convenient for the mortar to be fully mixed in the later stage, and the existing mortar raw materials will cause dust to fly during the grinding process, resulting in waste, and it is easy to pollute the atmosphere during the production process environment, and a large amount of dust accumulates in a space during the manufacturing process, which can easily cause a dust explosion. Therefore, it is necessary to invent a raw material grinding device for mortar production with dust recovery function
