Abstract
The utility model discloses an industrial ammonium nitrate fine crusher. A plurality of ring grooves are provided on the inner wall of a machine body, a plurality of layers of annuli racks are arranged on a main shaft and provided with a plurality of pins, and each pin is sheathed in an annulus capable of being pressed towards the ring grooves of the machine body under centrifugal action. By the industrial ammonium nitrate fine crusher, when the main shaft rotates, the annuli are pressed towards the ring grooves under the centrifugal action, so as to generate autorotation and revolution motion around the main shaft. The ammonium nitrate granules are fed into the machine from a feeding port in the upper part of the machine body, finely ground under the strong friction, extrusion and shearing actions of the annuli when passing through the annuli and the ring grooves on the inner wall of the machine body, and discharged from a discharge port in the lower part of the machine body. Each layer of annuli rack is provided with a plurality of annuli, a certain phase angle is provided between the annuli in the adjacent annuli racks, so that the ammonium nitrate granules are subjected to rolling action of the annuli in the course of moving from top to bottom. Therefore, the fineness of the ammonium nitrate at the discharge port is about 200 mesh.
Description
Technical field
The utility model is used for the in small, broken bits of industrial ammonium nitrate.
Background technology
Industrial ammonium nitrate is the primary raw material of manufacture explosive, according to the commercial explosive production technology, at first will carry out coarse crushing to industrial ammonium nitrate, carries out in small, broken bits again.The more little performance that just can guarantee commercial explosive more of ammonium nitrate fineness.
At present, generally adopt two kinds of equipment in small, broken bits in the commercial explosive manufacturing enterprise: 1. cam pulverizer: by the high speed rotation (2900rpm) of impeller, material is produced the intense impact shear action, but only can be crushed to about 80 orders, 2. crushing mill: the rotation by rolling wheel and around the revolution of main shaft produces friction, extruding and shear action to material.But it belongs to the discontinuous production equipment, and production efficiency is low, and because rotating speed low (25rpm), its pulverization is not strong, and fineness also only can be about 80 orders.
The utility model content
For improving at present industrial ammonium nitrate unfavorable situation in small, broken bits, technical problem to be solved in the utility model is to provide a kind of ammonium nitrate smashing fineness to surpass 200 purpose fine crushers.
The further technical problem to be solved of the utility model is that a kind of safe and reliable industrial ammonium nitrate fine crusher is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of industrial ammonium nitrate fine crusher is provided, at the body inwall multiple tracks annular groove is arranged, main shaft is provided with multilayer ring wheel support, on multilayer ring wheel support a plurality of bearing pins are arranged, one in cover can be pressed to the ring wheel of body annular groove under the action of the centrifugal on each bearing pin.
The beneficial effects of the utility model are: during main axis rotation, ring wheel is pressed in the annular groove of body under action of centrifugal force, produces rotation and around the revolution motion of main shaft.Ammoniumnitrate prill is fallen in the machine by the charging aperture of body upper, during through ring wheel and body inwall annular groove, is encircled the strong friction extruding of wheel and shear action and in small, broken bits, by the discharging opening outflow of underpart.Because a plurality of ring wheels are arranged in each layer ring wheel support, ring wheel in the adjacent ring wheel support is provided with certain phase angle again, therefore ammoniumnitrate prill constantly is subjected to encircling the spreading effect of wheel, so the ammonium nitrate fineness of discharging opening reaches about 200 orders in the process of motion from top to bottom.
As further improvement in the technical proposal, above-mentioned body is different with the material of ring wheel, and one hard one is soft, and body is a cast iron, and the ring wheel is cast aluminium.Can guarantee so not produce spark in the running process, so there is not potential safety hazard.
Description of drawings
Fig. 1 is the front projection figure of commercial explosive raw material ammonium nitrate fine crusher.
Among the figure: 1, synchronous pulley, 2, main shaft, 3, the ring wheel support, 4, bearing pin, 5, the ring wheel, 6, body, 7, base plate, 8, charging aperture, 9, discharging opening.
The specific embodiment
In the accompanying drawing, processing multiple tracks annular groove on the inwall of circular body 6, be enclosed within main shaft 2 and be provided with multilayer ring wheel support 3, be provided with a plurality of bearing pins 4 in multilayer ring wheel support 3, ring wheel 5 of each bearing pin 4 overhead cover, during main shaft 2 rotations, ring wheel 5 is under action of centrifugal force, press in the annular groove of body 6, produce rotation and around the revolution motion of main shaft 2.Ammoniumnitrate prill is fallen in the machine by the charging aperture 8 on body 6 tops, during through ring wheel 5 and body 6 inwall annular grooves, strong friction, extruding and the shear action of being encircled wheel 5 are and in small, broken bits, and by discharging opening 9 outflows of body 6 bottoms, the ammonium nitrate fineness of discharging opening 9 has reached about 200 orders.
The stepless speed regulation in 200 ~ 350rpm scope of the rotating speed of main shaft 2, ring wheel 5 and body 6 no percussions.Body 6 is different with the material of ring wheel 5, and one hard one is soft, and body 6 is a cast iron, and ring wheel 5 is a cast aluminium.Above-mentioned fine crusher can guarantee not produce spark in the running process, so there is not potential safety hazard.Because a plurality of ring wheels 5 are arranged in each layer ring wheel support 3, ring wheel 5 in the adjacent ring wheel support 3 is provided with certain phase angle again, therefore ammoniumnitrate prill constantly is subjected to encircling the spreading effect of wheel 5, so the ammonium nitrate fineness of discharging opening 9 reaches about 200 orders in the process of motion from top to bottom.
