Description

Crusher

The utility model relates to a pulverizer. Background technique

At present, there are a large variety of crushers on the market. It usually consists of a hammer, a rotor, a body, a casing, and a motor. The working principle is that the rotor is first driven by the motor to rotate the rotor and the hammer on the rotor. After the material is impacted by the hammer, the qualified pores are discharged from the sieve hole. However, the crushing efficiency of these conventional shredders is not high.

The patented product (Chinese Patent Publication No. CN 1830568A) proposes a novel structure of two rotors having two feed ports and two crushing chambers, and the rotors with hammers in the two crushing chambers are rotated at a high speed, and A flow guiding device for guiding and diverting the material is disposed between the two rotors. When the first crushing chamber is pulverized and the unqualified material enters the second crushing chamber under the action of the flow guiding device, the hammer is crushed by the hammer in the second crushing chamber, and the second crushing chamber is crushed and unqualified. Under the action of the flow guiding device, it enters the first pulverizing chamber, and is crushed by the hammer piece in the first pulverizing chamber. The unqualified material is pulverized and pulverized until it is qualified, and then sieved through a sieve provided at the bottom of the pulverization chamber. Although the pulverization efficiency is effectively improved, since the flow guiding device is fixed to the frame, in order to prevent the material from being bounced back by the flow guiding device, the rotor can only rotate in one direction and cannot change direction. This causes the material to hit only one side of the hammer and the other side of the hammer cannot be impacted. This greatly reduces the utilization of the hammer. Summary of the invention

The purpose of the utility model is to provide a pulverizer which can effectively improve the utilization rate of the hammer.

In order to achieve the above object, the utility model provides a pulverizer, which comprises a base and a frame fixed on the base. The frame is provided with a feeding port, and the frame is provided with an accommodating space for accommodating the space. A first rotor and a second rotor are disposed under the inlet, at least three sets of first hammers are arranged around the first rotor, and at least three sets of second hammers are arranged around the second rotor, and the bottom edge of the accommodating space extends continuously. To the sides of the feed inlets at both ends a screen is arranged on the edge, a gap is arranged on the frame, a turnable flow guiding device is arranged between the first rotor and the second rotor, and a connecting rod is arranged on the deflecting flow device, and the connecting rod is placed through the gap Outside the rack, the two ends of the deflectable flow guiding device are connected to the inner wall of the frame through a positioning shaft. When the rotor is reversing, the rotation of the connecting rod can be held by the connecting rod, so that the material can smoothly hit the other side of the hammer.

Among them, one of the two inlets of the pulverizer can be used to fill the air, and another feed port is fed.

Further, the top end of the connecting rod is provided with a fixed key. Because the material impact can be transferred to the deflector device very strongly, when the reversible deflector is reversed, the fixed button can make the turntable flow device fixed in one position without the impact of material collision.

Due to the flow guiding action of the deflectable flow guiding device, one side of the hammer piece is worn due to the impact of the material, and the pulverizing efficiency is greatly reduced. At this time, the rotor is moved in the reverse direction, and the deflectable flow guiding device is turned, so that the other side of the hammer is crushed by the impact of the material. In this way, both sides of the hammer can be utilized, which doubles the service life of the hammer.

The advantages of the utility model are:

1) causing both sides of the hammer to be impacted by the material, thereby improving the utilization of the hammer;

2) The rotor can change the direction of rotation, which is convenient for production. DRAWINGS

The present invention will be further described below in conjunction with the embodiments. It should be understood that these embodiments are for illustrative purposes only. The invention is not intended to limit the scope of the invention. In addition, it should be understood that various modifications and changes may be made to the equivalents of the present inventions. Within the required range.

Example 1

As shown in FIG. 1 and FIG. 2, the utility model provides a pulverizer comprising a base 1 and a frame 2 fixed on the base 1. The frame 2 is provided with a feeding port 4, and the frame 2 is provided with a receiving device. a space 3, a first rotor 5 and a second rotor 6 are disposed in the accommodating space 3 and below the feed port 4. A first hammer 7 is disposed around the first rotor 5, and a second hammer is disposed around the second rotor 6. 8. The bottom edge of the accommodating space 3 extends until the side edges of the feed ports 4 at both ends are provided with a screen 14, and the frame 2 is provided with a gap 12 between the first rotor 5 and the second rotor 6. A reversible flow guiding device 9 is provided.

As shown in FIG. 3 and FIG. 1, the deflectable flow guiding device 9 is provided with a connecting rod 10, and the connecting rod 10 is placed outside the frame 2 through the gap 12, and both ends of the deflectable flow guiding device 9 are connected through the positioning shaft 11 On the inner wall of the frame 2.

The material enters the accommodating space 3 by the two inlets 4 respectively. The first rotor 5 and the second rotor 6 in the accommodation space 3 are rotated at a high speed. The material entering the accommodating space 3 is pulverized by the impact of the first hammer 7 on the first rotor 5 and the second hammer 8 on the second rotor 6, respectively. The pulverized material is sieved through a screen 14. Due to the guiding action of the deflectable flow guiding device 9, when the material that has not been sieved by the first rotor 5 is crushed and hits the second hammer piece 8 on the second rotor 6, it is pulverized, and at the same time, due to the reversible flow guiding device 9 The guiding action is to pulverize when the material that has not been sieved by the second rotor 6 is crushed by the second hammer 7 on the first rotor 5. The unqualified material is pulverized and crushed until it passes, and then sieved through the sieve 14 provided at the bottom of the pulverization chamber.

However, when the first rotor 5 and the second rotor 6 are turned, due to the guiding action of the deflectable flow guiding device 9, when the first rotor 5 and the second rotor 6 are pulverized, the unqualified material will turn and collide. The flow device 9 is bounced back, so that the purpose of improving the pulverization efficiency is not achieved. At this time, the connecting rod 10 of the deflectable flow guiding device 9 can be pushed, so that the deflectable flow guiding device 9 can also be turned at the same time, and at this time, the material that is not sifted through the first rotor 5 will hit the second rotor 6 smoothly. The second hammer piece 8 is pulverized, and at the same time, the material which has been sifted by the second rotor 6 and sifted out will smoothly hit the first hammer piece 7 on the first rotor 5 to be pulverized. Example 2

As shown in FIG. 4 and FIG. 5, the second embodiment is different from the first embodiment in that the top end of the link 10 is provided with a fixed key 13, and both ends of the deflectable flow guiding device 9 are connected to the frame 2 through the positioning shaft 11. On the inner wall.

The working principle of the embodiment 2 is the same as that of the embodiment 1, except that after the deflectable flow guiding device 9 is turned, it can be fixed to the frame 2 by the fixing key 13.

Example 3

As shown in FIG. 6, the present embodiment is different from the first embodiment in that one end of the air supply device 14 is disposed in the axial direction of the accommodating space 3, and the other end of the air supply device 14 extends to the Outside the rack 2. The other structure is the same as that of the embodiment 1.
