Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically to an impact abrasive crusher. Background Technology

[0002] An impact crusher is a high-efficiency device that uses a high-speed rotating rotor to accelerate and propel materials, achieving crushing through impact and collision between the material and a fixed liner or other materials. Due to its advantages such as a large crushing ratio, good product particle shape, and high energy utilization, it is widely used in mining, building materials, metallurgy, chemical and other industries for medium and fine crushing and sand making of medium-hard and harder materials.

[0003] Currently, the mainstream impact crushers on the market are mainly divided into two types: vertical shaft impact crushers and horizontal shaft impact crushers. Their core working principle is to accelerate the material through the throwing heads or hammers on the rotor, giving it enormous kinetic energy, and then have it impact the peripheral guard plates or impact plates. Under the strong impact force, the material is crushed. Simultaneously, the material vortex formed within the crushing chamber also generates mutual collisions and friction between materials, further grinding and shaping them. However, existing impact crushers still have certain shortcomings in use: 1. The impact plates used for crushing are prone to damage during long-term use, but existing impact crushers do not have a structure for easy replacement and maintenance of the impact plates; 2. Crushed abrasive will produce a lot of waste chips. These waste chips mixed inside the crushed abrasive will affect the quality of the abrasive. The abrasive will need to be screened again later, which will increase the number of subsequent processing steps.

[0004] To address the aforementioned issues, we have implemented an innovative design based on the existing impact abrasive crusher structure. Utility Model Content

[0005] The purpose of this utility model is to provide an impact abrasive crusher to solve the problems mentioned in the background art, such as the impact plates of existing impact crushers being prone to damage during long-term use, the lack of a structure for easy replacement and maintenance of the impact plates, the generation of a large amount of waste chips during crushing, the impact chips mixed inside the crushed abrasive, which affects the quality of the abrasive and requires further screening, increasing the number of subsequent processing steps.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an impact abrasive crusher, comprising a machine body and support legs for supporting it; an upper cover plate is fixedly connected to the upper end of the machine body by fastening bolts, and a feed inlet is fixedly installed on the upper end of the upper cover plate; a protective cover is fixedly installed inside the machine body, and a servo motor is fixedly installed inside the protective cover; a throwing disc is fixedly connected to the output end of the servo motor, and a centrifugal plate is fixedly installed inside the throwing disc; a partition is fixedly installed inside the machine body, and an impact plate is provided between adjacent partitions; and a discharge assembly is provided at the bottom of the machine body.

[0007] Preferably, the centrifugal plates are distributed at equal angles on the inner side of the slinging tray, and the centrifugal plates are set at an angle of 45 degrees relative to the rotation plane of the slinging tray.

[0008] By adopting the above technical solution, the centrifugal plate can be set so that the abrasive material rotating at high speed inside the throwing disc can be thrown towards the inner wall along the inclined surface of the centrifugal plate.

[0009] Preferably, the partitions are distributed at equal angles on the circumference of the inner side of the machine body, dividing the crushing chamber into multiple independent crushing areas.

[0010] By adopting the above technical solution, the impact plate can be divided into multiple crushing zones through the setting of the partition, thereby facilitating the replacement of the impact plate.

[0011] Preferably, the working surface of the impact plate is covered with a high-chromium cast iron wear-resistant liner.

[0012] By adopting the above technical solution and installing high-chromium cast iron wear-resistant liners, the service life and crushing effect of the impact plate can be improved.

[0013] Preferably, the servo motor is connected to a frequency converter to precisely control the rotation speed of the material throwing disc.

[0014] By adopting the above technical solution and setting the frequency converter, the rotation speed of the throwing disc can be controlled, thereby changing the magnitude of the centrifugal force of the throwing disc and improving or changing the crushing effect of the abrasive.

[0015] Preferably, the discharge assembly includes a filter screen, which is fixedly installed at the bottom of the machine body and has an inverted cone shape when viewed from the front.

[0016] By adopting the above technical solution and setting up a filter screen, waste chips, dust and other impurities generated during crushing can be discharged through the filter screen.

[0017] Preferably, the discharge assembly includes a discharge pipe and a solenoid valve. The discharge pipe is fixedly installed at the center point of the filter screen, and the solenoid valve is fixedly installed on the outside of the discharge pipe. The solenoid valve is powered by an external power source.

[0018] By adopting the above technical solution and setting up a solenoid valve, the opening state of the discharge pipe can be controlled.

[0019] Compared with the prior art, the beneficial effect of this utility model is that the impact abrasive crusher is equipped with: 1. Crushing structure: In this structure, the abrasive falls into the throwing disc in the upper crushing chamber inside the machine body through the feed port. Then, the servo motor runs, and the output end of the servo motor drives the throwing disc to rotate at high speed, generating centrifugal force. The centrifugal force causes the abrasive to be thrown against the inner wall through the gap between the centrifugal plates and violently collide with the impact plates installed between the partitions. At the same time, the materials collide with each other, causing them to be crushed, thereby achieving the effect of impact crushing of the abrasive. 2. The structure facilitates the replacement of the impact plate. When the impact plate is damaged and needs to be replaced after a long period of use, the upper cover plate can be removed by rotating the fastening bolts in the opposite direction. After the upper cover plate is removed, the top of the impact plate is no longer restricted, and the impact plate can be removed from the adjacent partition for replacement. After replacement, the cover plate can be reinstalled on the upper part of the machine body by tightening the fastening bolts. Through the above structure, the impact plate can be quickly replaced. 3. Discharge structure: After the abrasive is ground, it enters the inner side of the lower crushing chamber. The powdery abrasive waste falls to the upper part of the filter screen and is discharged through the filter screen, while the granular abrasive rolls down the inclined surface of the filter screen to the upper part of the discharge pipe. When it is necessary to discharge the granular abrasive, the solenoid valve is operated to open the discharge pipe and discharge the granular abrasive from the discharge pipe.
