Description

Technical Field

[0001] This application belongs to the field of crushers, and particularly relates to a cage crusher row wheel striking rod and a cage crusher. Background Art

[0002] The cage crusher is designed based on the impact crushing principle and consists of main components such as a frame, a casing, a large cage wheel group, a small cage wheel group, and two motors. During operation, one motor drives the large cage to rotate forward, and the other motor drives the small wheel to rotate backward. The material enters the inner cage through the hopper, and the steel bars repeatedly impact and crush the material, thereby achieving the effect of finely crushing the material. The cage crusher can crush various single materials with a water content of less than 40%, especially suitable for materials with relatively high hardness. It has the advantages of simple and compact structure, small floor area, convenient maintenance, good crushing effect, stable operation, and easy cleaning, and is widely used in industries such as chemical fertilizers, building materials, petrochemicals, and fine chemicals.

[0003] The cage is composed of two relatively rotating cages, a large one and a small one. Each cage has a steel disc vertically fixed on the shaft, and two circles of striking rods are assembled concentrically perpendicular to the steel disc. The striking rod is an important component and a vulnerable working part of the cage crusher, playing an important role in the material processing and effective operation of the equipment. However, the main disadvantages of the cage crusher are that the row wheel striking rod is prone to wear, has a short service life, high production and replacement costs, and produces a large amount of noise during production operation, which is not conducive to green environmental protection production and the occupational health of workers.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0019] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0020] In the embodiments of the present application, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

[0021] The cage mill is designed according to the impact crushing principle and consists of main components such as a frame, a casing, a large cage wheel group, a small cage wheel group and two motors. When working, one motor drives the large cage to rotate forward, and the other motor drives the small wheel to rotate backward. The material enters the inner cage through the hopper, and the steel bars repeatedly impact and crush the material, so as to achieve the effect of finely crushing the material. The cage mill can crush various single materials with a water content of less than 40%, especially suitable for materials with a relatively large hardness. It has the advantages of simple and compact structure, small floor area, convenient maintenance, good crushing effect, stable operation and easy cleaning, and is widely used in industries such as chemical fertilizers, building materials, petrochemicals, and fine chemicals.

[0022] The squirrel cage is composed of two relatively rotating cages of different sizes. Each cage has a steel disc vertically fixed on the shaft. Two circles of striking rods are assembled concentrically perpendicular to the steel disc. The striking rods are important components and vulnerable working parts of the squirrel cage crusher, playing an important role in the material processing and effective operation of the equipment. However, the main disadvantages of the squirrel cage crusher are that the striking rods of the running wheels are prone to wear, have a short service life, high production replacement costs, and produce a lot of noise during production operation, which is not conducive to green environmental protection and occupational health.

[0023] See Figure 1 , this application provides a striking rod for the running wheel of a squirrel cage crusher, including a tungsten steel cylinder 2 and a rubber buffer layer 1.

[0024] The outer wall of the tungsten steel cylinder 2 is provided with limiting holes 20. The rubber buffer layer 1 is attached to the inside of the tungsten steel cylinder 2 through a hot vulcanization process. The rubber buffer layer 1 is provided with limiting nails 10, and the limiting nails 10 are nested in the limiting holes 20.

[0025] This kind of striking rod for the running wheel makes full use of the wear resistance of tungsten steel material and the shock absorption and high elasticity of rubber material. It adopts an overall design of the inner and outer layer composite process structure. The rubber buffer layer 1 is vulcanized and attached inside the tungsten steel cylinder 2, increasing the wear resistance of the striking rod for the running wheel and protecting the rubber buffer layer against puncture and tearing. It effectively reduces the problems of wear and noise of the striking rod for the running wheel, improves the service life of the striking rod for the running wheel, and at the same time reduces the overall weight of the striking rod for the running wheel, greatly reducing the energy consumption of equipment use.

[0026] In addition, when the rubber buffer layer 1 is severely damaged after being used for a period of time, the rubber buffer layer 1 can be directly replaced, and a new rubber buffer layer 1 is vulcanized on the inner wall of the tungsten steel cylinder 2 instead of replacing the entire striking rod for the running wheel, so the replacement cost is effectively reduced.

[0027] In this application, the rubber buffer layer 1 is of a cylindrical structure. Similarly, the tungsten steel cylinder 2 is also of a cylindrical structure. Of course, the rubber buffer layer 1 can also be set as a square cylinder structure, and the corresponding tungsten steel cylinder 2 can also be set as a square cylinder structure. In addition, the rubber buffer layer 1 can also be set as a cylindrical structure of other polygons, so the tungsten steel cylinder 2 also needs to be set as the corresponding polygonal cylindrical structure.

[0028] In order to further ensure the connection performance between the rubber buffer layer 1 and the tungsten steel cylinder 2, in some embodiments, the outer wall of the rubber buffer layer 1 is covered with limiting nails 10, the tungsten steel cylinder 2 is covered with limiting holes 20, and each limiting hole 20 is inlaid with a limiting nail 10.

[0029] Specifically, in the embodiments shown in the present application, each limiting nail 10 is distributed in an array on the outer wall of the rubber buffer layer 1. The limiting hole 20 is a through-hole structure, and the limiting holes 20 are also distributed in an array on the tungsten steel cylinder 2. Each limiting hole 20 is inlaid with a limiting nail 10, so that the overall connection between the rubber buffer layer 1 and the tungsten steel cylinder 2 is more firm.

[0030] In some embodiments, the limiting nail 10 is vertically inlaid in the limiting hole 20. This improves the integrity of the rubber buffer layer 1 and the tungsten steel cylinder 2.

[0031] Of course, in other embodiments, the limiting nail 10 can also be inclined on the outer wall of the rubber buffer layer 1, or the inclination angles of the limiting nails 10 are different and connected to the outer wall of the rubber buffer layer 1.

[0032] In some embodiments, the end face of the limiting nail 10 is flush with the outer wall of the rubber buffer layer 1.

[0033] Specifically, the depth of the limiting hole 20 is the same as the height of the limiting nail 10, and the end face of the limiting nail 10 is set to an arc structure adapted to the outer wall of the tungsten steel cylinder 2. In this way, when the limiting nail 10 is inlaid in the limiting hole 20, the end face of the limiting nail 10 is flush with the outer wall surface of the rubber buffer layer 1, and the appearance flatness of the overall rat cage crusher row wheel striking rod is better.

[0034] In addition, the present application also provides a cage mill, including any one of the above-mentioned cage mill row wheel striking rods.

[0035] In the description of this specification, the descriptions with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example.
