Abstract
Description
Technical Field
[0001] This utility model relates to the field of crushing equipment, specifically to a roller surface cleaning device for a roller crusher and a roller crusher. Background Technology
[0002] Roller crushers, especially double-toothed roller crushers, are key equipment for medium and fine crushing operations and are widely used in industries such as sintered ore, coal, cement, silicate materials, glass and ceramics. They exhibit excellent crushing efficiency for brittle materials with medium to low hardness.
[0003] However, in traditional technologies, after completing the crushing task, these crushers often leave a large amount of crushed material residue on their roller surfaces. This residue not only occupies roller space but can also lead to decreased subsequent crushing efficiency and fluctuations in product quality. More significantly, the removal of this residue often relies on manual operation, which not only increases labor intensity but also prolongs equipment downtime for maintenance, reducing overall production efficiency and economic benefits.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention
[0005] (a) Technical problems to be solved
[0006] This utility model provides a roller surface cleaning device for a roller crusher and a roller crusher, and at least solves the technical problem of how to improve the efficiency of roller surface cleaning of a roller crusher.
[0007] (II) Technical Solution
[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0009] A roller surface cleaning device for a roller crusher includes:
[0010] The nozzle is disposed in the crushing chamber of the roller crusher and is provided with a buffer chamber, a main nozzle and a side nozzle. The buffer chamber is used to connect to an air source. The main nozzle and the side nozzle are connected to the buffer chamber and are arranged toward the roller in the crushing chamber. The main nozzle extends in the front direction toward the buffer chamber. The side nozzle is located in the same plane as the main nozzle and is provided on each side opposite to the main nozzle. The side nozzle is inclined to the main nozzle.
[0011] When the gas source supplies gas to the buffer chamber, the airflow from the main nozzle and the side nozzles is distributed in a fan shape.
[0012] In some embodiments, the nozzle includes a hollow stud tube communicating with the buffer chamber. The hollow stud tube is provided with external threads and is threadedly connected to the wall of the crushing chamber through the external threads for connecting to an air source.
[0013] In some embodiments, at least two nozzles are spaced apart along the length of the roller.
[0014] In some embodiments, the nozzles are located on both sides of the roller in the width direction.
[0015] In some embodiments, the main nozzle is arranged perpendicular to the axis of the roller.
[0016] In some embodiments, the diameter of the main nozzle gradually increases along the airflow direction.
[0017] This utility model also discloses a roller crusher, including the above-mentioned roller surface cleaning device, crushing chamber and roller.
[0018] In some embodiments, the crushing chamber is enclosed by four side plates, and the nozzle is disposed on the side plates.
[0019] (III) Beneficial Effects
[0020] Compared with the prior art, the roller surface cleaning device and roller crusher of the present invention have the following beneficial effects:
[0021] When the roller surface cleaning device and roller crusher are working, air is supplied to the buffer chamber through an air source. The airflow in the buffer chamber is then blown out simultaneously from the main nozzle and side nozzles. Since the side nozzles and the main nozzle are located in the same plane, and there is at least one side nozzle on each side opposite to the main nozzle, and the side nozzles are inclined to the main nozzle, the airflow from the main nozzle and the side nozzles is distributed in a fan shape. This fan-shaped airflow can blow the material off the roller surface, thereby reducing material residue. Compared with the existing manual cleaning method, the roller surface cleaning device and roller crusher of this invention can clean the roller surface by air blowing through nozzles, improving the efficiency of roller surface cleaning of the roller crusher.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0028] After crushing materials, existing double-toothed roller crushers often leave crushed material residue on their roller surfaces, affecting reuse. This usually requires manual cleaning, which is time-consuming and labor-intensive.
[0029] To solve the above-mentioned technical problems, this embodiment provides a roller surface cleaning device for a roller crusher. Please refer to [link to relevant documentation]. Figures 1 to 4 As shown, Figure 1 This is a perspective view of the roller crusher and roller surface cleaning device in the embodiment. Figure 2 This is a top view of the roller crusher and roller surface cleaning device in the embodiment. Figure 3 This is a perspective view of the nozzle in the embodiment. Figure 4 This is a cross-sectional view of the nozzle in the central plane in the embodiment.
[0030] The roller surface cleaning device of the roller crusher in this embodiment includes: a nozzle 1.
[0031] like Figure 1 As shown, nozzle 1 is located inside the crushing chamber 2 of the roller crusher, as... Figure 3 and Figure 4 As shown, the nozzle 1 is provided with a buffer chamber 11, a main nozzle 12 and a side nozzle 13. The buffer chamber 11 is used to connect to the air source. The main nozzle 12 and the side nozzle 13 are connected to the buffer chamber 11 and are arranged towards the roller 3 in the crushing chamber 2. The main nozzle 12 extends in the front direction of the buffer chamber 11. The side nozzle 13 is located in the same plane as the main nozzle 12 and is provided on each of the opposite sides of the main nozzle 12. The side nozzle 13 and the main nozzle 12 are inclined and have a certain angle, which is usually an acute angle. When the air source supplies air to the buffer chamber 11, the airflow of the main nozzle 12 and the side nozzle 13 is distributed in a fan shape.
[0032] The roller surface cleaning device described above utilizes an efficient air source to supply airflow to the buffer chamber 11 during operation. This airflow is then released synchronously through a carefully designed main nozzle 12 and side nozzle 13 system. Because the side nozzles 13 and main nozzle 12 are cleverly arranged on the same horizontal plane, and the side nozzles 13 are inclined relative to the main nozzle 12, this layout ensures that the airflow widely covers the roller surface in a fan-shaped pattern. This fan-shaped airflow distribution not only enhances the impact force of the airflow but also widens the cleaning range, effectively and quickly and thoroughly blowing away the material adhering to the roller surface, significantly reducing the amount of material residue. Compared to traditional manual cleaning methods, this roller surface cleaning device achieves automated cleaning, significantly improving the cleaning efficiency of the roller crusher's roller surface, significantly reducing the labor intensity of operators, shortening equipment downtime for maintenance, and thus improving overall production efficiency and economic benefits. Furthermore, the device has a simple structure, is easy to install and maintain, and provides a strong guarantee for the continuous and stable operation of the roller crusher.
[0033] In one embodiment where the nozzle 1 is disposed within the crushing chamber 2, see [reference needed]. Figure 1 and Figure 4 As shown, the nozzle 1 includes a hollow stud tube 14 that communicates with the buffer chamber 11 and is used to connect the air source. The hollow stud tube 14 is provided with external threads and is threadedly connected to the wall of the crushing chamber 2 through the external threads. This installation method is not only simple and quick to install, but also has a firm and reliable connection, effectively preventing loosening or falling off due to vibration or impact.
[0034] For example, the hollow stud tube 14 is integrally formed with or threadedly connected to the cavity wall of the buffer cavity 11.
[0035] To achieve better cleaning results and higher cleaning efficiency, the number and spacing of the nozzles 1 can be set according to the size of the roller 3. For example, see [reference needed]. Figure 2 As shown, at least two nozzles 1 are spaced apart along the length of the roller 3. Simultaneously, the nozzles 1 are located on both sides of the roller 3 in the width direction. This dispersed arrangement of multiple nozzles 1 ensures effective airflow scouring throughout the entire length of the roller 3, avoiding blind spots and significantly reducing material residue on the roller surface.
[0036] The direction of nozzle 1 can be set as needed; for example, see [reference needed]. Figure 2 As shown, the main nozzle 12 is arranged perpendicular to the axis of the roller 3. It can be understood that the main nozzle 12 can also be in the same axial direction as the roller 3.
[0037] To increase the coverage area of the airflow from the main nozzle 12, refer to... Figure 4 As shown, the diameter of the main nozzle 12 gradually increases along the airflow direction, forming an expanding orifice structure. This design makes the output airflow more uniform and covers a larger area.
[0038] This embodiment discloses a roller crusher, see reference. Figure 1 and Figure 2 As shown, the roller surface cleaning device, crushing chamber 2 and roller 3 mentioned above are included. The use of the roller surface cleaning device realizes automated cleaning, which not only greatly improves the cleaning efficiency of the roller crusher roller surface, but also significantly reduces the labor intensity of operators, shortens the equipment downtime for maintenance, and thus improves the overall production efficiency and economic benefits.
[0039] For example, the crushing chamber 2 is surrounded by four side plates 20, and the nozzle 1 is provided on the side plate 20, such as being connected to the pre-set threaded hole on the side plate 20 through the hollow stud tube 14 mentioned above.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
