Background
At present, the production of ceramic wall and floor tiles adopts a technological method of slurry spray drying to prepare powder, then pressing and forming, and sintering to obtain the product. In the spray drying pulverizing section, it is necessary to atomize slurry by high pressure while injecting hot air at about 600 ℃ into the dryer, and spray the atomized slurry into the dryer. In the flow field in the dryer, under the action of strong surface tension, the high-pressure ceramic slurry automatically forms balls, countercurrent heat exchange reaction is carried out between the slurry and hot air flow in the rising process of the slurry, concurrent heat exchange reaction is carried out between the slurry and the hot air flow in the falling process of the slurry, and powder is formed after water is evaporated. The method is mature in technology, is widely adopted at present, has high energy consumption and high electricity consumption, takes about 130 yuan for preparing 1 ton of powder, brings great environmental pollution, needs to treat various harmful gases generated by combustion, has great CO2 emission and is a thing which is necessary for ceramic manufacturing industry.
The dry powder preparation is based on the wet dehydration of slurry, the drying by waste heat or the sun drying by solar energy, the low-temperature drying to form mud blocks with the water content of 8-10%, and the crushing to form powder by a crushing machine. Therefore, a pulverizer with simple structure, convenient assembly and maintenance and suitable for dry powder making needs to be developed.
Disclosure of Invention
The utility model aims to provide a pulverizer for pulverizing mud blocks through impact.
The technical scheme adopted for solving the technical problems is as follows: an impact pulverizer, characterized by: including vertical round tank body, a jar body central authorities installation pivot is installed in the pivot and is got rid of the chain that a plurality of axial intervals were laid, and the first motor of dust extraction mouth, feed inlet and drive pivot is installed at the top of jar body, and the discharge gate is installed to the bottom.
On the basis of the above, the tank body is internally provided with a wall scraping device which is used for scraping the inner wall of the tank body in a rotating way, the outer wall of the upper port of the tank body is provided with a rotary flange, the rotary flange is used for fixing the wall scraping device, and the wall scraping device is driven by a second motor.
On the basis, a plurality of chain hanging discs are axially and uniformly fixed on the rotating shaft, a plurality of chain hanging grooves for hanging the chain throwing are uniformly formed on the circumference of the chain hanging disc, the chuck is arranged on the chain hanging disc and is provided with a claw for blocking and preventing the chain throwing from being separated from the chain hanging groove.
The utility model has the beneficial effects that: the impact crusher adopts the chain throwing impact mud blocks to crush the mud blocks into powder, is particularly suitable for crushing mud blocks with high mud content and high water content, and has the characteristics of simple structure and convenient maintenance.

Detailed Description
As shown in fig. 1-5, an impact crusher comprises a vertical round tank body 1, a rotating shaft 2 is arranged in the center of the tank body 1, a plurality of chain slingers 3 which are distributed at intervals in the axial direction are arranged on the rotating shaft 2, a dust extraction port 1.1, a feed port 1.2 and a first motor 4 for driving the rotating shaft 2 are arranged at the top of the tank body 1, and a discharge port 1.3 is arranged at the bottom of the tank body. The can body 1 is mainly composed of a conventional can 11, a top cover 12 and a bottom cover 13. The dust extraction port 1.1 and the feeding port 1.2 are arranged on the top cover 12, and the discharging port 1.3 is arranged on the bottom cover 13. The top cover 12 and the bottom cover 13 are respectively provided with bearings for supporting the rotating shaft 2, and the bearings are additionally arranged for sealing and dust prevention. The mud blocks enter the tank body 1 from the feed inlet 1.2 and are impacted by the chain throwing 3 which runs at high speed, and the crushed particles are about 0.1-1 mm. The flexible chain throwing device is suitable for crushing mud blocks with large mud content and high water content, and can not cause accumulation and blocking of the chain. During the impact crushing of the ceramic clay blocks, a great amount of dust is inevitably generated, and the dust is sealed inside the tank body and pumped to the bag-type dust collector for treatment from a dust pumping port. Wherein, the bearing of the rotating shaft 2 arranged on the bottom cover 13 can adopt a floating bearing so as to adjust the concentricity of the upper bearing and the lower bearing.
In order to prevent powder from accumulating on the tank wall, a wall scraper 5 which rotates and scrapes the inner wall of the tank body 1 is arranged in the tank body 1, a rotary flange 6 is arranged on the outer wall of the upper port of the tank body 1, the wall scraper 5 is fixed by the rotary flange 6, and the wall scraper 5 is driven by a second motor 7. The main structure of the wall scraper 5 is a rotating frame, the periphery of which is fixedly provided with an axially extending scraper, and the scraper is supported by a rotating flange to rotate in the tank body 1, so that the wall scraper 5 is convenient to detach from the top of the tank body 1 during maintenance. The top end of the wall scraper 5 can form an outward-expanding cone hopper, which can guide feeding and can also prevent mud from scattering to the transmission mechanism of the wall scraper 5.
For the dismouting of convenient chain 3 that gets rid of, a plurality of chain hanging dish 8 are evenly fixed to pivot 2 axial, and a plurality of chain hanging groove 8.1 that are used for hooking chain 3 are evenly offered to chain hanging dish 8 circumference, install chuck 9 on the chain hanging dish 8, and chuck 9 is formed with and is used for blocking the jack catch 9.1 that prevents chain 3 from getting rid of chain hanging groove 8.1. During maintenance, the chain throwing 3 can be disassembled and assembled through the elastic chuck 9 from the maintenance hole of the tank body 1, and the chain throwing 3 is very convenient to maintain and replace.
