Description

Technical Field

[0001] The present application belongs to the field of pulverizer manufacturing technology, and specifically relates to a vertical pulverizer. Background Art

[0002] In currently used vertical shaft impact mills, after the material is fed into the crushing chamber, it is accelerated horizontally by a high-speed rotating body, achieving a crushing operation in which the material hits the material and the material hits the iron. In vertical shaft hammer mills and vertical shaft plate hammer mills, the material fed into the crushing chamber is successively crushed by the hammers or plate hammers on the high-speed rotating body. The disadvantages are: 1. In vertical shaft impact mills, the material is crushed in the chamber in a unidirectional motion, and the material is crushed only a few times, resulting in incomplete crushing. 2. In vertical shaft hammer mills and vertical shaft plate hammer mills, the material passes through the crushing hammers in the crushing chamber in sequence, but there is a certain gap between the hammers or plate hammers and the inner wall of the crushing chamber. Once the material is crushed to below 3-5 mm, it is difficult to crush it further, resulting in low crushing efficiency and high consumption of wearing parts. Summary of the Invention

[0003] The purpose of this application is to address the shortcomings of the existing technology. A vertical crusher is designed by installing a gathering hammer on a rotating body. Not only can the material be hammered and crushed by the high-speed rotating gathering hammer in the crushing chamber, but also because the high-speed rotating gathering hammer has the function of intercepting the material in the crushing chamber and throwing it up at high speed, the gathering hammer intercepts the material in the crushing chamber and throws it up at high speed. The material that is continuously thrown up at high speed is in the shape of an inverted cone and covers the discharge channel, so that the material in the chamber can fully realize the crushing operation of material hitting material and material hitting iron, and the power consumption is small, the consumption of wearing parts is low, and the crushing efficiency is high, thereby overcoming the problem that there is a certain gap between the inner wall of the crushing chamber and the crushing hammer, which makes the material cannot be effectively crushed.

[0004] To achieve the above object, the technical solution of the present invention is:

[0005] A vertical crusher comprises a crusher body. A crushing cavity of the crusher body is provided with a rotary body and a rotary hammer, and the rotary hammer is mounted on the rotary body.

[0006] Preferably, the rotary hammer comprises a hammer body and a protrusion, the hammer body is provided with the protrusion, and the protruding direction of the protrusion is in the working rotation axial direction of the hammer body.

[0007] Preferably, the outer edge of the protrusion is acute-angled in the rotation direction of the rotating body.

[0008] Preferably, the side of the protrusion which is consistent with the rotation direction of the rotating body is in the shape of an inwardly concave arc.

[0009] Preferably, the outer edge of the protrusion and the outer edge of the hammer body have the same hammering function.

[0010] Preferably, the outer edge of the protrusion is aligned with the outer edge of the hammer body.

[0011] Preferably, it further comprises a base, the pulverizer body and the driving mechanism are both mounted on the base, and the driving mechanism is connected to the rotating body in a transmission manner.

[0012] Preferably, an upper hopper is provided at the top end of the pulverizer body, and a lower hopper is provided at the bottom end of the pulverizer body.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The present application adopts the method of installing the gathering hammer on the rotating body to design a vertical crusher, which not only makes the material in the crushing chamber be hammered and crushed by the high-speed rotating gathering hammer, but also because the high-speed rotating gathering hammer has the function of intercepting the material in the crushing chamber and throwing it up at high speed, the gathering hammer intercepts the material in the crushing chamber and throws it up at high speed. The material thrown up continuously at high speed is in the shape of an inverted cone and covers the discharge channel, so that the material in the chamber can fully realize the crushing operation of material hitting material and material hitting iron, and the power consumption is small, the consumption of wearing parts is low, and the crushing efficiency is high, thereby overcoming the problem that there is a certain gap between the inner wall of the crushing chamber and the crushing hammer, which makes the material cannot be effectively (finely) crushed.

[0015] 2. The present application intercepts the material falling in the crushing cavity through the protrusion, thereby throwing the material up and crushing it.

[0016] 3. The acute angle on the protrusion in this application can be inserted between the falling material and the inner lining plate. At the same time, during the rotation of the hammer body, the acute angle gathers the material onto the hammer body during rotation. The rotating hammer body generates centrifugal force on the material, thereby throwing the material up. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1-3As shown, a vertical crusher includes a crusher body 1 , a crushing cavity of the crusher body 1 is provided with a rotary body 2 and a rotary hammer, and the rotary hammer is installed on the rotary body 2 .

[0022] As a preferred embodiment, the rotary hammer comprises a hammer body 3 and a protrusion 4, wherein the protrusion 4 protrudes in the axial direction of the working rotation of the hammer body 1. The protrusion 4 intercepts the material falling in the crushing cavity and realizes the effect of throwing the material up.

[0023] As a preferred method, Figure 3 As shown, the outer edge of the protrusion 4 forms an acute angle in the rotation direction of the rotating body 2. This arrangement, on the one hand, causes the falling material to be hammered and crushed between the liner 9 and the hammer body 3 in the crushing chamber. On the other hand, the acute angle of the protrusion 4 on the hammer body 3 gathers the falling material into the hammer body 3 at an acute angle. The centrifugal force generated by the high-speed rotation of the hammer body 3 throws the material gathered in the hammer body 3 at an acute angle, achieving a crushing operation in which the material hits the material and the material hits the iron (the liner 9, that is, the inner wall of the crushing chamber).

[0024] In this embodiment, during pulverization, after the material enters the pulverizing chamber from the upper hopper 7 above the pulverizer body 1, the rotor 2 in the pulverizing chamber rotates, driving the gathering hammer to rotate. The gathering hammer then strikes the material entering the pulverizing chamber. Simultaneously, the rotation of the gathering hammer causes the protrusion 4 on the hammer to gather some of the falling material onto the hammer. Under the action of centrifugal force, the material is thrown up in an inverted cone shape (the shape of the material thrown up is an inverted cone shape), thereby achieving a pulverization operation between the high-speed thrown material and the liner 9, the falling material, or other rotating bodies. Part of the pulverized material is continuously gathered by the protrusion 4 of the gathering hammer during its falling process. The high-speed thrown material is pulverized, overcoming the problem of a certain gap between the inner wall of the pulverizing chamber and the pulverizing hammer, which prevents the material from being effectively (finely) pulverized.

[0025] As a preferred embodiment, the protrusion 4 is in an inwardly concave arc shape facing the same side as the rotating body 2 in the same rotation direction.

[0026] As a preferred embodiment, the outer edge of the protrusion 4 and the outer edge of the hammer body 3 have the same hammering function.

[0027] As a preferred embodiment, the outer edge of the protrusion 4 is aligned with the outer edge of the hammer body 3. This arrangement allows the hammer body 3 to be fully utilized, so that the material between the outer edge of the hammer body 3 and the inner lining plate 9 is fully hammered and crushed.

[0028] As a preferred embodiment, the pulverizer further comprises a base 5, on which the pulverizer body 1 and the driving mechanism 6 are mounted, and the driving mechanism 6 is connected to the rotating body 2. The driving mechanism 6 is a motor.

[0029] As a preferred embodiment, an upper hopper 7 is provided at the top of the pulverizer body 1 , and a lower hopper 8 is provided at the bottom of the pulverizer body 1 .
