[0002] The cage crusher is a type of crusher that allows granular materials with appropriate moisture content to enter the inner and outer cage-shaped crushing rotors through the feed inlet. Through their high-speed relative motion, the materials are crushed to the fineness required by the customer. The crushed materials are then collected by a powder selection and dust collection system and transported in a dust-free manner by a screw conveyor.

Poor discharge efficiency can easily lead to material accumulation and blockage in the crushing chamber, which not only further reduces operating efficiency but may also cause equipment overload and accelerated component wear due to material retention, increasing maintenance costs and downtime risks. At the same time, inefficient crushing is often accompanied by high energy consumption, and dust overflow and material waste caused by poor discharge can also have adverse effects on the operating environment and production economy, making it difficult to adapt to high-requirement crushing scenarios and the diverse material processing needs.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Example 1:
[0037] Please see Figure 1 - Figure 5 This embodiment provides a cage crusher for efficient crushing, the specific idea of which is as follows:
[0038] A cage crusher includes a mounting base 1, and the cage crusher also includes a first cage rotor 2, a second cage rotor 208, and crushing components.
[0039] The first squirrel cage rotor 2 and the second squirrel cage rotor 208 are both located on the inner side of the top of the mounting base 1 and are used to crush materials.
[0040] The crushing component is used to drive the first squirrel cage rotor 2 and the second squirrel cage rotor 208 to rotate relative to each other. By driving the first squirrel cage rotor 2 and the second squirrel cage rotor 208 to move relative to each other through a single drive, the material is crushed efficiently.
[0041] As examples, in this embodiment, the broken component includes:
[0042] The motor 201, which plays a driving role, is installed on one side of the mounting base 1.
[0043] The speed reducer 202, which controls the speed, is installed on one side of the motor 201.
[0044] The mounting bracket 203, which serves to install the gearbox, is fixedly connected to the upper surface of the gearbox 202.
[0045] The first bevel gear 204, which serves as a connector, is rotatably connected to the inner side of one end of the mounting bracket 203. The connecting shaft 205, which serves as a fixing component, is fixedly connected to one side of the first bevel gear 204.
[0046] It should be noted that a second bevel gear 206 is rotatably connected to the inner side of one end of the mounting bracket 203, a bushing 207 is fixedly connected to the outer side of one end of the second bevel gear 206, a first squirrel cage rotor 2 is fixedly connected to the outer side of the end of the bushing 207, and the outer side of the connecting shaft 205 is rotatably connected to the inner side of the second bevel gear 206 and the bushing 207.
[0047] The housing 209 is fixedly connected to the inner top of the mounting base 1, and the second squirrel cage rotor 208 is located inside the housing 209.
[0048] In addition, a connecting channel 210 is connected to one side of the housing 209, and a cyclone dust collector 211 is installed on the outer side of the end of the connecting channel 210.
[0049] The other end of the connecting channel 210 is detachably connected to a dust collection cylinder 212 for receiving dust.
[0050] It should be noted that the working principle of the cyclone dust collector 211 is based on centrifugal force separation. The dust-laden airflow enters the cylindrical shell of the cyclone dust collector 211 tangentially. The high-speed rotation generates a strong centrifugal force, which causes the dust particles to be thrown against the cylinder wall of the cyclone dust collector 211 and fall down along the wall surface, and finally be discharged from the bottom ash hopper. The purified airflow moves upward along the central axis and is discharged from the top outlet, thus achieving air-dust separation. The remaining small dust particles enter the inner side of the dust collection cylinder 212 through the connecting channel 210.
[0051] Example 2:
[0052] Please see Figure 1 - Figure 5 This embodiment provides a cage-type pulverizer that facilitates dust collection, and its specific concept is as follows:
[0053] A cage crusher includes a mounting base 1, and the cage crusher also includes a spiral fan blade 3 and a discharge component.
[0054] The spiral fan blade 3 is located below the mounting base 1 and is used to discharge dust.
[0055] The discharge component, under the linkage of the first bevel gear 204, can drive the spiral fan blade 3 to rotate, thereby discharging the collected dust.
[0056] As examples, in this embodiment, the discharge component includes:
[0057] The third bevel gear 301, which serves as a connector, is rotatably connected to the inner side of one end of the mounting bracket 203.
[0058] The first pulley 302, which serves as the connecting element, is fixedly connected to one side of the third bevel gear 301. In addition, a fixing plate 305 is fixedly connected to the inner side of the bottom end of the mounting base 1, and the fixing plate 305 is connected to the inner side of the discharge cylinder 304.
[0059] The discharge cylinder 304, which serves to discharge materials, is fixed to the inner side of the bottom end of the fixing plate 305.
[0060] The second pulley 303, which serves as a connector, is rotatably connected to the outer side of one end of the discharge cylinder 304. The second pulley 303 and the third bevel gear 301 are connected by a belt. The spiral fan blade 3 is rotatably connected to the inner side of the discharge cylinder 304. The second pulley 303 and the discharge cylinder 304 are fixedly connected.
[0061] One side of the discharge cylinder 304 is connected to the outer side of the bottom end of the cyclone dust collector 211.
[0062] It should be noted that the first bevel gear 204 can drive the spiral fan blade 3 to rotate under the linkage action. Without the need for an additional drive device, the spiral fan blade 3 can be used to discharge material, and the collected large particles of impurities can be discharged through the spiral fan blade 3, which increases the automation level of the device.
[0063] Working principle:
[0064] When using this device, the user can inject the material into the inside of the box 209 through the top of the box 209. At this time, the user can start the motor 201. The motor 201 drives the first bevel gear 204 to rotate through the reducer 202. The rotation of the first bevel gear 204 will drive the connecting shaft 205 to rotate. The rotation of the first bevel gear 204 will drive the second bevel gear 206 to rotate through the third bevel gear 301. At this time, the connecting shaft 205 drives the second squirrel cage rotor 208 to rotate. The second bevel gear 206 drives the first squirrel cage rotor 2 to rotate through the bushing 207. Thus, the material can be crushed by the relative rotation of the first squirrel cage rotor 2 and the second squirrel cage rotor 208. At the same time, the dust generated inside the box 209 can be absorbed by the cyclone dust collector 211 and then collected by the dust collection cylinder 212.
[0065] This cage crusher combines compactness and high efficiency in its design. The equipment occupies a small area and has a short manufacturing process, saving installation space and production costs. Driven by a multi-stage transmission mechanism driven by motor 201, the first bevel gear 204 simultaneously drives the connecting shaft 205 and the second bevel gear 206 to rotate, causing the second cage rotor 208 to rotate relative to the first cage rotor 2. Combined with the high wear resistance of the alloy first cage rotor 2 and the second cage rotor 208, the dual rotational shearing and impact action achieves high crushing fineness, ensuring that the injected material is fully crushed. The equipment has high airtightness, and with the cyclone dust collector 211, the dust generated during the crushing process is absorbed in real time, effectively controlling dust diffusion. This avoids environmental pollution or affecting the health of operators, and it can adapt to a wide range of applications such as fertilizers, feed, and other chemical products, achieving high efficiency, cleanliness, and multi-functionality in crushing operations.
[0066] When the third bevel gear 301 rotates, it can drive the first pulley 302 to rotate. The first pulley 302 drives the second pulley 303 to rotate via a belt. When the second pulley 303 rotates, it will drive the spiral fan blade 3 to rotate inside the discharge cylinder 304. At this time, the dust discharged by the cyclone dust collector 211 will fall into the inside of the discharge cylinder 304 and then be discharged through the spiral fan blade 3.
[0067] The third bevel gear 301 drives the second pulley 303 to rotate via transmission, allowing the dust falling into the discharge cylinder 304 to be smoothly discharged through the spiral fan blades 3, forming a complete dust treatment process of "absorption-transportation-discharge". This not only avoids dust accumulation inside the equipment affecting operating efficiency, but also simplifies subsequent cleaning work. This design, which organically combines crushing transmission and dust treatment transmission, improves the environmental protection and practicality of the equipment while ensuring crushing effect, and is suitable for operation scenarios with requirements for material crushing and dust control.
[0068] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
