Description

Raw material milling equipment is used in special mortar production

Technical Field

The utility model relates to the technical field of special mortar production, in particular to a raw material grinding device for special mortar production.

Background

Mortar is a binding substance used for brickwork in a building, and is prepared by adding water into sand and cementing materials (cement, lime paste, clay and the like) in a certain proportion, and is also called mortar and also used as mortar. The mortar is usually cement mortar, mixed mortar (or cement mortar), lime mortar and clay mortar. The special mortar is one kind of mortar and is mainly suitable for heat preservation, sound absorption, water resistance, corrosion resistance, radiation protection, decoration, adhesion and other special requirements.

In the production process of the special mortar, the raw materials are milled by a milling device so as to facilitate the later deep processing; although the existing grinding device can achieve the grinding effect, the grinding effect is not very good, and slightly larger particles are mixed in the grinding device, so that the grinding is not thorough, and the later processing is affected.

Therefore, the improvement of the prior art is carried out by those skilled in the relevant technical field, for example, a "raw material grinding device for special mortar production" proposed by chinese patent publication No. CN217614998U is provided, and the raw material grinding device for special mortar production is provided with two grinding rollers inside the main box, and the two grinding rollers are mutually rotated reversely through the cooperation of the main gear and the slave gear, so that the raw material can be firstly ground for the first time, so that the grinding rotor for the later grinding is enabled to grind the ground raw material more carefully, and by arranging the V-shaped filter plate inside the main box, the V-shaped filter plate can effectively filter the first ground raw material, the thinner raw material can flow into the inside of the arc-shaped storage tray through the V-shaped filter plate for grinding, slightly larger raw material flows out of the main box and falls into the inside of the collecting box, and staff can collect and grind again, so that the grinding effect is better and more thorough.

However, the technical solution in the application document still has the disadvantage that, for example, the large-particle raw materials after filtration in the utility model also need to be manually poured into the box again, which increases the workload of staff and reduces the efficiency of the whole equipment.

To achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a raw material grinding device for producing special mortar, which comprises a crushing box and a grinding box, wherein the crushing box is arranged at the top end of the grinding box; the crushing box comprises a shell and a filtering cylinder, the filtering cylinder is rotationally arranged in the inner cavity of the shell, two rotating crushing rollers are arranged in the filtering cylinder, a feeding disc is arranged at one end of the shell, a discharging hole is formed in the bottom end of the shell, and the discharging hole is located right above the feeding hole of the grinding box.

The utility model has the preferable technical scheme that the front end of the shell is hinged with a cover plate, the feeding disc is arranged on the cover plate, and the crushing roller is arranged on the cover plate.

The utility model has the preferable technical scheme that the crushing roller is arranged at the lower end of the feeding disc.

The cover plate and the shell are sealed by end faces, and sealing gaskets are arranged on the cover plate corresponding to the sealing faces.

The utility model has the preferable technical scheme that the rear end of the shell is provided with a driving motor, and the output end of the driving motor penetrates through the shell and is connected with the filtering cylinder.

The preferable technical scheme of the utility model is that a plurality of filter sieve holes are uniformly distributed on the filter cylinder, and a plurality of stirring teeth are arranged on the inner wall of the filter cylinder at intervals.

The beneficial effects of the utility model are as follows:

according to the raw material grinding device for producing the special mortar, the special mortar is crushed by the crushing box to be crushed for the first time, the massive raw materials are crushed, and then the later-stage grinding box is used for grinding, so that the grinding efficiency can be improved, and the grinding is finer. In broken incasement, carry out effectual filtration through the filter cylinder, thinner raw materials grinds from the milling box of discharge gate entering below, and thicker raw materials can roll through pivoted filter cylinder again and get into the crushing roller and break, so repeatedly until the whole milling box that gets into of last raw materials. The repeated pouring of unfiltered raw materials by manpower is reduced.
