Abstract

The utility model relates to an internal-cooling double-roller mill, which is composed of an upper and a lower box bodies, a gear and a pair of grinding rollers, wherein, coolant channels are arranged in a pair of grinding rollers of a double-roller mill in axial direction in a snake shape or a helical shape. The utility model can effectively solve the problem of the heating-up of the double-roller mill in use, and thus the processing temperature of material can not be higher than 8 DEG.

Description

The inner-cooled roller-crushing mill

The utility model relates to the roller-crushing mill of pulverizing oil plant and spice.

Traditional roller-crushing mill causes grinding roller and material to heat up simultaneously owing to rub with material at work, generally can reach seven, 80 degree.Have heat sensitive material for some, for example the material that oil content is high, contain the spice of escaping gas etc., processed under so high temperature, can destroy the quality of material.If can solve the intensification problem of grinding roller, just can finish process smoothly, improve the quality that grinds material.

The purpose of this utility model is to provide a kind of inner-cooled roller-crushing mill that improves thermo-responsive material processing quality effectively.

The utility model is made up of a pair of grinding roller (6), belt pulley (5), gear wheel (11), pinion (10), upper box (1) and lower box (8); Described belt pulley (5) is driven by power motor, drives grinding roller (6) work by bearing (4); It is characterized in that: in a pair of grinding roller (6) of roller-crushing mill, axially snakelike or spirality is placed with coolant channel; Coolant channel one end in the grinding roller (6), by the roll shaft internal channel of the same side, be connected the coolant channel other end with the refrigeration machine air entry by coolant outlet (2), by the roll shaft internal channel of this side, be connected with the refrigeration machine exhaust outlet by coolant inlet (9).

The inner-cooled roller-crushing mill structure that the utility model adopted utilizes cooling agent to finish the cooling of grinding roller, can solve roller-crushing mill effectively in the intensification problem in when work, makes the Gao Buhui of processing temperature of material be higher than 8 degree.

The drawing explanation:

Fig. 1 is that the overall structure that the utlity model has the spirality coolant channel is implemented illustration.

Fig. 2 is the integrally-built left view of the utility model.

Fig. 3 is the utility model overall structure A-A cutaway view.

Fig. 4 is the expansion schematic diagram that the utlity model has snakelike coolant channel.

Fig. 5 is the schematic diagram of the utility model roll shaft coolant outlet part.

Concrete structure of the present utility model can be referring to accompanying drawing: among Fig. 1, upper box (1) and lower box (8) constitute the shell of roller-crushing mill, and the grinding roller of roller-crushing mill is fixed its inside.The roll shaft of described grinding roller both sides exposes to upper and lower casing place coolant outlet (2) and coolant inlet (9) respectively, is provided with seal member (3) between described import and export (9), (2) and roll shaft.In the grinding roller (6), be arranged with coolant channel (7) along its axial screw.Described cold true agent passage (7) is connected with cooling agent import and export (9), (2) by both sides roll shaft passage, and described import and export (9), (2) are connected with row, the air entry of refrigeration machine.Also comprise belt pulley (5) among Fig. 1; Bearing (4).Among Fig. 2, pinion (10), gear wheel (11) are arranged.Among Fig. 4, reflection be another coolant channel embodiment of grinding roller (6), in grinding roller (6), along its axial snakelike coolant channel (12) that is arranged with, coolant channel is for launching schematic diagram among the figure.Other parts are identical with the structure of Fig. 1.Among Fig. 5, in the seal member (3), by spring (16) burnishing surface of two rotary packing rings (15) is pressed onto stationary seal ring (14) side in its outside, the other both ends of the surface of stationary seal ring (14) are close to sealer shell (17), (18) respectively, realize movable sealing.
