Stone powder mill
The utility model relates to a device for making powder with building stones.
The pulverizer is widely applied to the industries of chemical industry, mines, steel, thermal power, coal and the like, and aims to pulverize ores, coal and the like into powder for use. The existing flour mill is complex in structure, after a crusher crushes massive materials to required feeding granularity, a bucket elevator conveys the materials to a storage bin, then the materials are uniformly conveyed into a grinding cavity of the flour mill by an electromagnetic vibration feeder, a scraper knife shovels the materials in the process of rotating with a grinding roller and throws the materials into a space between grinding rings of the grinding roller to form a padding layer, and the materials are ground between the grinding roller and the grinding rings, so that the purpose of milling is achieved. The ground powder is carried to an analyzer by the airflow of a fan for powder selection, fine powder meeting the fineness requirement enters a cyclone collector along with the airflow through a pipeline for separation and collection, the fine powder is discharged by a discharger to obtain finished powder, and the airflow is sucked into a blower by a return air pipe at the upper end of the cyclone collector. The undesirable powder is thrown to the outer wall by the blades and separated from the airflow, and the coarse powder particles fall into the grinding chamber for re-grinding under the action of self gravity.
The pulverizer is large in size and high in manufacturing cost, and is suitable for large-scale industrial production. And for some small businesses the cost is unacceptable.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a stone material pulverizer, its simple structure smashes effectually.
In order to solve the technical problem, the technical scheme of the utility model is to adopt a stone material pulverizer, which comprises a shell, wherein a feed inlet and a discharge outlet are arranged on the shell; the method is characterized in that: a horizontal rotating shaft is arranged in the shell, and a hammer head rotating along with the rotating shaft is arranged on the rotating shaft; a plurality of arc toothed plates which are connected end to end are arranged in the shell along the outer edge of the rotating track of the hammer head; one surface of each toothed plate, which is close to the hammer, is provided with teeth, and a gap is reserved between the toothed plate and the hammer; the toothed plates are arranged in a step shape, and the gap between each toothed plate and the hammer head is from wide to narrow along the rotating direction of the hammer head to form a plurality of independent crushing cavities; the discharge hole is connected with an exhaust fan. The utility model discloses a principle utilizes tup and pinion rack to smash the building stones step by step, recycles the air exhauster and absorbs the powder through the screen cloth filtration. The pinion rack is the echelonment and arranges to the interval of every pinion rack and tup is littleer gradually, makes the building stones beat into the powder by smashing along with the rotation of tup gradually. Multistage pinion rack can form a plurality of broken chambeies, smashes into the powder and has improved crushing efficiency. The number of crushing chambers can be designed according to the actual situation.
As an improvement, a buffer spring is arranged between the toothed plate and the shell. Avoid unable kibbling material to damage pinion rack and tup.
As a further improvement, an adjusting screw is fixed on the back of the toothed plate, and the buffer spring is sleeved on the adjusting screw; the adjusting screw penetrates through the shell and is locked by a nut. So that the spacing between the toothed plate and the housing is adjustable.
As another further improvement, the feed inlet is arranged at the top of the shell, and a rebound toothed plate is arranged in the feed inlet; and a baffle is arranged between the toothed plate on the side opposite to the rebounding toothed plate and the shell. The rebound toothed plate is used for rebounding thrown stones during extrusion, and the baffle is used for preventing the stones from entering a cavity between the toothed plate and the shell, so that objects can be sufficiently crushed in the machine and are not easy to throw out of the machine.
As an improvement, the baffle extends to the motion trail of the hammer head to form a V-shaped backflow cavity. The airflow lifted by the hammer head is blocked by the baffle to rotate, so that the air pollution caused by the gushing of the airflow from the feeding hole is avoided.
As an improvement, the discharge port is arranged at the top of the shell and is communicated with the crushing cavity; and a screen is arranged in the discharge port. The screen mesh filters the pulverized powder, and only the powder meeting the requirements can pass through the screen mesh.
As an improvement, the pinion rack of pivot top is for being curved monoblock, and pivot side is the echelonment with the pinion rack of transferring and arranges.
As an improvement, the rotating shafts are two parallel shafts, and no toothed plate is arranged between the rotating shafts.
As an improvement, the rotating directions of the two rotating shafts are opposite. The effect is achieved through the mode that the plate hammers strike each other, the abrasion of the hammers can be reduced, and the consumption of electric energy is reduced.
The utility model discloses an useful part lies in: the stone pulverizer with the structure has the advantages of simple structure and good pulverizing effect. The effect is achieved through the crushing mode of the tooth plate hammer, the rotary hammer and the tooth plate form a crushing cavity, the abrasion of the hammer can be reduced through the crushing mode, the consumption of electric energy is reduced, and therefore the production cost is reduced; the yield is high; the prismatic shape of the crushed product is good; the wearing parts consume little, are suitable for ferrosilicon, coal grinding, have high efficiency, output large, characteristic such as being low of energy consumption.
