Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, and in particular to a crushing device that is easy to maintain. Background Technology

[0002] Crushing equipment has a wide range of applications. It can be used to grind flour, crush feed, finely grind pigments and raw / cooked cement materials, grind slurries to prepare suspensions, and increase the flowability and filling properties of materials. Furthermore, crushing equipment can be used to grind materials awaiting artificial drying to accelerate the drying process, finely grind catalysts and adsorbents to enhance their catalytic efficiency and adsorption effects, and grind coal into coal powder to improve combustion speed and completeness. Crushing equipment is an indispensable part of modern industrial production, and its development and application play a vital role in improving production efficiency, reducing energy consumption, and improving product quality. However, crushing devices are prone to some problems during prolonged use:

[0003] Maintenance is relatively troublesome. During the processing of raw materials, the existing crushing equipment suffers from prolonged crushing of solid particles. This not only causes the crushing blades inside the equipment to be damaged by friction due to prolonged stress, leading to increased temperature and a higher failure rate, but also generates dust over time, which can easily cause problems such as jamming. To ensure the normal operation of the crushing equipment, regular maintenance is often required. However, most existing crushing equipment is a one-piece structure, which is not easy to disassemble and maintain. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pulverizing device that is easy to maintain.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0023] A convenient-to-maintain pulverizing device, as described in this embodiment, Figure 1-4 As shown, it includes a lower protective shell 1, a frame 2 welded to the bottom outer wall of the lower protective shell 1, and an upper protective shell 3 hinged to one side of the top of the lower protective shell 1. A rectangular feed inlet 4 is opened through the inner wall of one top end of the upper protective shell 3, and a feed hopper 5 is welded to the inner wall of the rectangular feed inlet 4. A rotating shaft 6 is rotatably installed at the axis of the lower protective shell 1, and a fixing slot 7 with equal spacing is welded to the outer wall of the rotating shaft 6. A crushing blade 8 is fixed to the inner wall of the fixing slot 7 by bolts, and a first pulley 9 is welded to one side of the outer wall of the rotating shaft 6. A fixing block 15 is welded to the same side of the outer wall of both the lower protective shell 1 and the upper protective shell 3, and a fixing pin 16 is inserted into the fixing block 15.

[0024] Its protective shell is designed to unfold from top to bottom, so if jamming occurs during the crushing process or internal maintenance is required, the internal parts can be quickly cleaned and maintained simply by opening the upper protective shell 3, greatly reducing the difficulty of subsequent maintenance work.

[0025] The outer wall of the first pulley 9 is fitted with a belt 10, and the bottom of the belt 10 is connected to a second pulley 11. The shaft of the second pulley 11 is connected to a servo motor 12. The bottom inner wall of the lower protective shell 1 is provided with a semi-cylindrical screen 13 along the inclined direction, and the inclination angle of the semi-cylindrical screen 13 is 5°-10°.

[0026] The lower protective shell 1 is located on the inner wall of the lowest end of the semi-cylindrical screen 13, and the unloading pipe 14 is welded thereon, and the unloading pipe 14 is arranged in an inclined direction.

[0027] A rectangular discharge port 17 is provided through the bottom outer wall of the lower protective shell 1, and a guide plate 18 is welded to one side of the bottom of the rectangular discharge port 17 along the inclined direction.

[0028] When crushing materials, multiple sets of detachable crushing blades 8 rotate continuously, which can effectively crush the materials. In addition, the inclined design of the semi-cylindrical screen 13 not only ensures that the crushed particles are of uniform size, but also allows impurities in the crushing process to be discharged from the bottom discharge pipe by gravity, so as not to affect the overall normal crushing process.

[0029] In this embodiment, the semi-cylindrical screen 13 is first fixed to the bottom inner wall of the lower protective shell 1 along the inclined direction. After fixing, the crushing blade 8 is fixed to the inside of the fixing slot 7 with bolts. After assembly, the upper protective shell 3 is covered, and the servo motor 12 is connected to the external power supply and started, thereby driving the internal crushing blade 8 to rotate continuously. Then, the raw material to be crushed is poured into the inside of the feed hopper 5. When the raw material comes into contact with the crushing blade 8, it will be continuously crushed to reduce the particle size. When the particles are crushed to the appropriate size, they are discharged from the semi-cylindrical screen 13. The remaining raw material particles will continue to roll downwards to be crushed. When there are solid particles that are difficult to crush or other impurities, they will roll down and be discharged from the discharge pipe 14 on one side. The qualified crushed solid particles at the bottom are directly discharged from the rectangular discharge port 17. When maintenance is required, simply stop the operation of the crushing device, remove the fixing pin 16, and open the upper protective shell 3 for maintenance. Example

[0030] A pulverizing device that is easy to maintain, such as Figure 1-4 As shown, this embodiment makes the following additions based on embodiment 1: the length of the crushing blade 8 is adapted to the inner wall radius of the semi-cylindrical screen 13, and the distance between the bottom outer wall of the crushing blade 8 and the inner wall of the semi-cylindrical screen 13 is 1-5 cm. The servo motor 12 is connected to an external switch through a wire, and the switch is connected to an external power source through a wire.
