Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, specifically to a horizontal multi-rotor impact mill. Background Technology

[0002] With the rapid development of lithium-ion battery materials, lithium-ion power batteries have entered a golden age. This has led to the development of multi-rotor impact mills, which typically consist of multiple high-speed rotating rotors. After material enters the grinding chamber, it is propelled at high speed by hammers, blades, or other impact components on the rotors, colliding and impacting multiple times with other rotors, stators, or the inner wall of the chamber, thereby crushing and refining the material particles. The simultaneous operation of multiple rotors increases the contact area and the number of collisions between the material and the rotors, allowing the material to be thoroughly crushed and refined in a short time, thus improving production efficiency and meeting the needs of large-scale production.

[0003] A prior art patent with publication number CN120022975A discloses a solution including a grinding box, a grinding unit, and a powder selection unit. The grinding box is fixedly installed on a support base, and a first end cover and a second end cover are detachably installed at both ends of the grinding box. A feeding hopper for feeding material into the grinding box is fixedly installed on the first end cover. The grinding unit includes a coarse grinding component for receiving material from the feeding hopper and a fine grinding component for receiving the feeding port of the coarse grinding component. The coarse grinding component circulates and grinds the material while conveying it axially. The fine grinding component further circulates and grinds the material that was not fully ground by the coarse grinding component while conveying it axially. This invention aims to solve the problems of existing horizontal multi-rotor mills, which are difficult to achieve fine and uniform grinding of materials, are not convenient to meet the requirements of high-precision grinding, have low material grinding efficiency, and are difficult to control the quality of the final product.

[0004] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:

[0005] First, the material falling back from the existing grading zone cannot fall directly into the crushing zone, which affects the crushing effect.

[0006] Second, the internal material airflow path of the equipment cannot effectively improve the crushing efficiency.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] In view of the shortcomings of the existing technology, this utility model solves the problems that the material falling back from the existing grading zone cannot fall directly into the crushing zone, which affects the crushing effect; and that the material airflow path inside the equipment cannot effectively improve the crushing efficiency.

[0009] To solve the above problems, this utility model provides the following technical solution:

[0010] A horizontal multi-rotor impact mill includes two parallel grinding chambers, and a classifying chamber connected by a channel is provided in the upper region between the two grinding chambers.

[0011] The crushing chamber is equipped with a crushing component that rotates inside. One end of the crushing chamber is fixedly connected to a feeding channel that is coaxially arranged with the center of the crushing component. An air filter is also connected to the feeding channel.

[0012] As an optimized solution, a toothed ring covering the crushing component is fixedly connected to the circumferential inner wall of the crushing chamber, and a crushing gap is provided between the toothed ring and the crushing component.

[0013] As an optimized solution, the gear ring is provided with an avoidance gap in the area where the channel is located.

[0014] As an optimized solution, a feed inlet is vertically and upwardly fixed to the side wall of the feed channel.

[0015] As an optimized solution, a screw feeder is connected to the feed inlet.

[0016] As an optimized solution, the crushing chamber is connected to a crushing shaft assembly on the end wall opposite to the feed channel.

[0017] As an optimized solution, the grading cavity is equipped with a grading component for rotation.

[0018] As an optimized solution, a grading shaft assembly is connected to one end wall of the grading cavity.

[0019] As an optimized solution, the grading shaft assembly and the crushing shaft assembly are located on the same side.

[0020] As an optimized solution, the crushing chamber and the crushing shaft are supported on the base.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] By setting a toothed ring on the wall of the crushing chamber and looping it around the outside of the crushing component, with a gap between the toothed ring and the crushing component, the position of the toothed ring and the crushing component can be adjusted to improve the crushing efficiency of the material.

[0023] The feeding channel is located on the center line of the crushing component, which can ensure that the incoming material is evenly contacted and crushed with the crushing component, thereby improving the crushing uniformity.

[0024] An air filter connected to the feed channel ensures clean airflow and improves the quality of the crushed material.

[0025] A screw feeder is installed at the feed inlet for convenient automatic feeding and controllable feed rate;

[0026] By adjusting the overall structure, the movement trajectory of the material inside the cavity was changed, thereby improving the crushing efficiency of the crushing equipment. Attached Figure Description
