Abstract

The utility model discloses a two-stage hammer type crusher without sieve bottoms. The utility model comprises a crushing depot; rotors are arranged between a feed inlet and a discharge hole of the crushing depot; a rotary disc of each of the rotors is hinged with a hammer head; the rotors are driven by a motor through belts; the rotors arranged in the crushing depot are an upper and a lower rotors, the axial lines of which are parallel; the lower rotor is arranged slantways below the upper rotor; a gap is arranged between the hammer head working surfaces of the upper and the lower rotors. Because the upper and the lower rotors are arranged, when falling, materials can be continuously beaten and crushed by the hammer heads on the upper and the lower rotors; a position where the mutual distance of the hammer heads of the two rotors is smallest has the largest crushing force, and materials can be entirely crushed into materials with granularity needed by technology. Because the crushing efficiency of the two rotors is higher, the materials can be completely crushed and no sieve bottom needs to be used.

Description

Twin-stage does not have sieve end beater grinder

Technical field

The utility model relates to a kind of beater grinder.

Background technology

Existing coal, sandstone size reduction machinery have multiple, beater grinder wherein is like this, the top, pulverizing storehouse of pulverizer is provided with feeding mouth, the bottom is provided with discharging opening, and the inside, pulverizing storehouse between feeding mouth and the discharging opening is provided with by motor-driven single rotor, is connected with tup on the circumference of rotor, because the power of single rotor is less, material moment pulverizing must can not be provided with the sieve end between the discharging opening of pulverizing the bottom, storehouse and rotor, fall to stop bulk materials.

This pulverizer is when work, material enters from the feeding mouth of pulverizing top, storehouse, tup rotates under the drive of rotor and beats material it is pulverized, and pulverizes only to hold the piece material of having pulverized at the bottom of the sieve of bottom, storehouse and fall from discharging opening output, and the sieve end can stop that bulk materials continues to pulverize in pulverizing the storehouse.The screening of material is carried out at this hammering type pulverizer utilization sieve end; when material ratio is wet; when wetting coal such as pulverizing, wet coal dust will stop up the sieve end, and material can't continue to fall; the material of pulverizing in the storehouse will be piled up more and morely; if do not shut down cleaning, rotor is stuck, and easily motor is burnt out; and frequently shut down cleaning, then reduced operating efficiency.In addition, the tup of this pulverizer and the link position of rotor are fixed, and the tup wearing and tearing shorten, and the back is just necessary to be changed, and the replacing of tup can consume a large amount of funds.

The utility model content

The purpose of this utility model is to provide a kind of crush efficiency height, the not susceptible to plugging twin-stage in pulverizing storehouse not to have sieve end beater grinder.

The technical solution of the utility model is: a kind of twin-stage does not have sieve end beater grinder, comprise and pulverize the storehouse, be provided with rotor between the charging aperture in pulverizing storehouse and the discharging opening, be hinged with tup on the rotating disk of rotor, rotor by belt by motor-driven, set rotor is upper and lower two rotors that axis is parallel in the pulverizing storehouse, and lower rotor part is located at the oblique below of upper rotor part, leaves the gap between the tup working face of upper and lower rotor.

Turning to of described upper and lower two rotors is identical.

The rotating disk of described upper and lower rotor is provided with the different tup installing hole of many group distances of shaft centers, and every group of tup installing hole all is to be evenly distributed on the equal diameter circumference of rotating disk.

Effect of the present utility model and advantage are: the utlity model has upper and lower two rotors, material falls can be pounded pulverizing by upper and lower epitrochanterian tup, has maximum pulverizing strength at the mutual nearest place of the tup of two rotors, can all be ground into the required granularity of technology to material, because two-spool crush efficiency is higher, material can be pulverized fully, need not to use the sieve end.

In addition, on the rotating disk of upper and lower rotor, be provided with distance of shaft centers many groups installing hole from the near to the remote, tup is after work a period of time, wearing and tearing shortened, efficient working range diminishes, the tup of wearing and tearing can be installed in apart from the installing hole far away of axle center, tup like this and the distance axle center are the state before efficient working range can return to wearing and tearing again, have prolonged the service life of tup, have saved fund.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the partial sectional view of Fig. 1.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, be provided with charging aperture 2 on the top of pulverizing storehouse 1, the bottom is provided with discharging opening 3, between charging aperture 2 and discharging opening 3, be provided with the

parallel rotor

4,5 of upper and lower two axis, lower rotor part 5 is installed in the oblique below of upper rotor part 4, rotor 4 is driven by motor 9 by belt transmission, and rotor 5 is driven by motor 10 by belt transmission.Upper rotor part 4 is to be made of three groups of coaxial rotating disks arranged side by side 6, all is hinged with 7, four tups 7 of four tups on the circumference of each rotating disk 6 and is hinged in four installing holes 8 of rotating disk 6, and four installing holes 8 are evenly to distribute on an equal diameter circumference of rotating disk 6.Lower rotor part 5 is identical with the structure of upper rotor part 4, hinged tup 13 on the rotating disk 12 of lower rotor part 5.Therefore upper and

lower rotor

4,5 is set as identical turning to, and two epitrochanterian tups 7 and the linear velocity direction of tup 13 at mutual nearest place are opposite, can produce bigger pulverizing strength.

In addition, except that installing hole 8, also be provided with distance of shaft centers apart from rotating disk 6 from far away and farther two groups of installing holes 14,15 on the rotating disk 6 of upper rotor part 4, installing hole 14,15 evenly distributes on two circumference of rotating disk 6 respectively.Tup 7 is after work a period of time, wearing and tearing shortened, efficient working range diminishes, the tup 7 of wearing and tearing can be installed in apart from the installing hole 14 far away of axle center, tup 7 like this and the distance axle center are the state before efficient working range can return to wearing and tearing again, in like manner after tup 7 continues wearing and tearing, tup 7 can be changed to apart from the farther installing hole 15 in axle center, make tup 7 can continue to use.Lower rotor part 5 is identical with upper rotor part 4 structures, also is provided with the different installing hole of many group distances of shaft centers on the rotating disk 12 of lower rotor part 5.

The utility model is when work, material is from the charging aperture input, material falls and is beaten pulverizing by 7 rotations of the tup on the upper rotor part 4, material continues to fall and is beaten pulverizing by 7 rotations of the tup on the lower rotor part 5 again, have maximum pulverizing strength at the mutual nearest place of the tup 7 of two rotors, can all be ground into the required granularity of technology to material, because the tup on the birotor has higher crush efficiency, material can be pulverized fully, need not to use the sieve end.
