Abstract

The utility model relates to a ring hammer crusher with an air volume adjustment device; through an adjustable wind-guide board arranged on a machine cover and a gap between a controling rotor and a body, the flow direction and the flow capacity of the inner airstream of the ring hammer crusher can achieve an ideal state at a charge port and a discharge port to cause the charge port not to exhaust air outward. The exhaust air rate of the discharge port is minimum, and thereby, dust pollution produced by rotor rotating is reduced, and working environment is clarified.

Description

Ring hammer crusher

The utility model relates to a kind of ring hammer crusher, particularly a kind of ring hammer crusher that has the exhaust air rate adjusting device.

The ring hammer crusher that uses does not have the exhaust air rate adjusting device at present, and the gap between rotor and the casing is changeless.Because the air-flow that the rotation of rotor produces is discharged in a large number from feeding mouth, cause dust from flying, air pollution, in addition since when adjusting material granularity to the change in gap between sieve plate support and the rotor, exhaust air rate is changed, because there is not the exhaust air rate adjusting device that this variation is revised, make its Rational flow, also increased the weight of the pollution of dust.

The purpose of this utility model is to provide a kind of ring hammer crusher that has the exhaust air rate adjusting device.It can make the flow direction of air-flow and flow reasonably be adjusted, and reduces the pollution of dust to air.

The purpose of this utility model is achieved in that the exhaust air rate adjusting device is housed on the cover of ring hammer crusher, it is by tunable wind-guiding plate and connection thereof, securing member is formed, the adjustment of tunable wind-guiding plate can be for rotating or translation, link with gyroaxis between wind deflector that rotates and the cover, adjustment can be adopted manually or machine driving.Slide between manual wind deflector and the cover, can adopt screw adjustment and fixing, also can adopt machine driving, adjust the angle or the position of tunable wind-guiding plate, just can control the gap between rotor and the cover, thereby make the air quantity that flows to feeding mouth controlled, reduce the pollution of dust.

The utility model can make the flow direction of air-flow and flow reach perfect condition at feeding mouth and discharging opening place, make not outwards air draft of feeding mouth, the exhaust air rate of discharging opening is within bottom line, thereby reduce the dust concentration that produces by the rotor rotation, be beneficial to the work of deduster, solved the dust pollution question of ring hammer crusher, purified working environment, it is healthy to be of value to the workman.

Below in conjunction with embodiment and accompanying drawing thereof, the utility model is described in further detail.

Fig. 1 is the general illustration of the utility model embodiment one.Exhaust air rate adjusting device 3 shown in the figure is a rotation formula.

Fig. 2 is the general illustration of the utility model embodiment two.Exhaust air rate adjusting device 3 shown in the figure is the translation form.

Fig. 3 is the structural representation of the exhaust air rate adjusting device of embodiment one.

Fig. 4 is a B-B cutaway view among Fig. 3.

Fig. 5 is an A-A cutaway view among Fig. 3.

Fig. 6 is the structural representation of the exhaust air rate adjusting device of embodiment two.

Fig. 7 is the securing member schematic diagram of embodiment two.

With reference to Fig. 1～7, describe the concrete structure of embodiment in detail.

1 is feeding mouth among Fig. 1 and Fig. 2, and 2 is that crushing shell, 3 is that tunable wind-guiding plate, 4 is that cover, 5 is that rotor, 6 is that body, 7 is that sieve plate support, 8 is that sieve plate, 9 is that sieve plate adjuster, 10 is a discharging opening.

One end of the tunable wind-guiding plate 12 among the embodiment one is installed on the cover by rotating shaft 13.The other end is equipped with bolt 11, have the garden deep-slotted chip breaker on the casing, bolt 11 can move in groove, driving tunable wind-guiding plate 12 13 rotates around the shaft, can change the gap between rotor and the cover, play the effect that air quantity is adjusted, bolt 11 is screwed, just can tunable wind-guiding plate 12 is fixing, outside the deep-slotted chip breaker of the garden of casing, be provided with dust cover 14, be screwed and be installed on the casing, the rotation of tunable wind-guiding plate 12, also can drive, for example adopt versions such as gear drive, worm-drive by other mechanical type.

Bracing frame 16 is housed on the cover among the embodiment two, bolt 15 is housed on bracing frame 16, bolt 15 lower ends and tunable wind-guiding plate 17 link with screw thread, swivel bolt 15, can make tunable wind-guiding plate 17 with cover and support 16 as on the chute, move down, change the gap on rotor top, play the effect that air quantity is regulated, after tunable wind-guiding plate 17 is adjusted, with jackscrew 18 it is withstood, also can be with it is moved in chute, fix with jackscrew then, the adjustment of the tunable wind-guiding plate 17 of translation also can be by the rack-and-pinion transmission form, tunable wind-guiding plate 17 and tooth bar be fixed together or be made as one, pass through gear driven.

Claims

1, a kind of ring hammer crusher, it comprises body, sieve plate, rotor, crushing shell and cover, it is characterized in that being equipped with on the cover exhaust air rate adjusting device, it by be installed in tunable wind-guiding plate on the cover and connection thereof, securing member is formed.

2,, it is characterized in that the tunable wind-guiding plate connects with cover by gyroaxis according to the said ring hammer crusher of claim 1.
