Description

Technical Field

[0001] The utility model belongs to the technical field of belt cleaning equipment, and particularly relates to a scraping type belt cleaner. Background Art

[0002] In industries such as mines, metallurgy, and chemical engineering, belt conveyors, as the main equipment for material transportation, their operating efficiency and stability directly affect the production capacity and quality of the entire production line. However, during long-term operation, belts often adhere to a large amount of materials. If these materials are not removed in a timely manner, it will not only increase the running resistance of the belt, resulting in increased energy consumption, but may also cause serious consequences such as belt deviation, increased wear, and even breakage. Therefore, the application of belt cleaners is particularly important.

[0003] Traditional scraping type belt cleaners usually use a whole rubber plate as the scraping component, and achieve material scraping by adjusting the contact pressure and angle between it and the belt. However, this design often seems powerless when facing large and highly viscous materials. Large materials are prone to driving the overall deformation of the rubber plate during the scraping process, resulting in poor scraping effect, and even damaging the rubber plate and the cleaner itself. In addition, in a high-temperature environment, the rubber plate is prone to thermal expansion, further reducing its scraping effect and service life.

[0004] To overcome these problems, some improved scraping type belt cleaners have emerged on the market, such as using multi-layer composite rubber plates and adding spring pressing devices. However, although these improvement schemes have certain effects in improving the cleaning efficiency and extending the service life, they still have not fundamentally solved the problems of difficult scraping of large materials and easy deformation of rubber plates in high-temperature environments. Summary of the Utility Model

[0005] Aiming at the above problems, the purpose of the utility model is to provide a scraping type belt cleaner, which solves the problems that the rubber plate is prone to overall deformation when scraping large materials in the existing belt cleaner, and in addition, in a high-temperature environment, the rubber plate is prone to thermal expansion, reducing the scraping effect and service life.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a scraping type belt cleaner, including a body base, double-headed bolts are inserted at both ends of the web of the body base, a tensioning mechanism is arranged on the double-headed bolts below the body base, rubber plates are fixed on both sides of the flange of the body base through fastening bolts, a pressure strip is arranged between the head end of the rubber plate and the fastening bolt, a plurality of ventilation holes are opened on the body base, and a plurality of notches are spaced apart at the top end of the rubber plate to form a serrated structure.

[0007] The beneficial effects of the present utility model are as follows: Multiple evenly distributed notches are cut on the surface of the rubber plate to form an effective serrated structure, so as to more effectively cut into the material and prevent the overall deformation of the rubber plate driven by large pieces of material; Multiple ventilation holes are opened on the body base inside the rubber plate to achieve an effective heat dissipation effect.

[0008] To ensure the heat dissipation effect of the ventilation holes on the rubber plate;

[0009] As a further improvement of the above technical solution: The multiple ventilation holes are arranged at equal intervals parallel to the rubber plate.

[0011] To ensure the installation stability of the rubber plate;

[0012] As a further improvement of the above technical solution: Through holes for slidingly sleeving fastening bolts are opened on the pressing strip, and both ends of the pressing strip are flush with the ends of the rubber plate.

[0015] As a further improvement of the above technical solution: The body base is of channel steel structure, the tensioning mechanism includes a spring, the spring is sleeved outside the double-headed bolt and is arranged between the body base and the nut, and the nut is threadedly connected to the double-headed bolt.

[0016] The beneficial effect of this improvement is that the double-headed bolt can be fixed on the belt conveyor, and then with the support of the nut and the spring, the end of the rubber plate can be pressed against the belt surface with appropriate pressure for cleaning.

[0017] To conveniently adjust the pressing force of the rubber plate on the belt;

[0018] As a further improvement of the above technical solution: A partition is sleeved on the double-headed bolt between the spring and the nut.

[0019] The beneficial effect of this improvement is that by rotating the nut, the partition can be pushed to move, and then the partition squeezes the spring, enabling the spring to support the body base with appropriate elasticity, so that the rubber plate is pressed against the belt with appropriate force.

[0020] To effectively improve the connection stability between the double-headed bolt and the body base;

[0021] As a further improvement of the above technical solution: a sliding sleeve is sleeved on the outer side of the stud bolt, the sliding sleeve is welded to the body base, and the spring is sleeved on the outer side of the sliding sleeve.

[0029] Embodiment 1:

[0030] As Figure 1—3 shows: a scraper-type belt cleaner, comprising a main body base 1, stud bolts 2 are inserted at both ends of the web of the main body base 1, a tensioning mechanism 6 is arranged on the stud bolts 2 below the main body base 1, rubber plates 3 are fixed to both sides of the flange of the main body base 1 by fastening bolts 5, a pressure strip 4 is arranged between the rubber plate 3 and the head end of the fastening bolt 5, a plurality of ventilation holes 11 are opened on the main body base 1, a plurality of notches 31 are arranged at intervals at the top end of the rubber plate 3 to form a serrated structure, and a plurality of evenly distributed notches 31 are cut on the surface of the rubber plate 3 1, forming an effective sawtooth structure, so as to cut into the material more effectively and avoid the deformation of the rubber sheet as a whole caused by the large piece of material; a plurality of ventilation holes 11 are provided on the main body base 1 inside the rubber sheet 3 to achieve an effective heat dissipation effect, and a plurality of the ventilation holes 11 are provided parallel to the rubber sheet 3 and are equidistantly spaced, and the heat accumulated between the two rubber sheets 3 can be smoothly discharged to the outside through the plurality of ventilation holes 11, so as to achieve effective cooling; a through hole for slidingly sleeve-connecting the fastening bolt 5 is provided on the pressure strip 4, and the two ends of the pressure strip 4 are flush with the end of the rubber sheet 3, and the pressure strip 4 can have The pressure area of ​​the rubber sheet 3 is effectively increased, so that the fastening bolts 5 can more effectively fix the rubber sheet 3. The main body base 1 is a channel steel structure. The tensioning mechanism 6 includes a spring 62, which is sleeved on the outside of the stud bolt 2 and arranged between the main body base 1 and the nut 64. The nut 64 is threadedly connected to the stud bolt 2, and the stud bolt 2 can be fixed on the belt conveyor. Then, the support of the nut 64 and the spring 62 is used to press the end of the rubber sheet 3 on the belt surface with a suitable pressure for cleaning. The double between the spring 62 and the nut 64 A partition 63 is mounted on the head bolt 2. By rotating the nut 64, the partition 63 can be pushed to move, thereby causing the partition 63 to squeeze the spring 62, so that the spring 62 supports the main body base 1 with a suitable elastic force, so that the rubber plate 3 is pressed against the belt with a suitable force. A sliding sleeve 61 is mounted on the outer side of the stud bolt 2. The sliding sleeve 61 is welded to the main body base 1, and the spring 62 is mounted on the outer side of the sliding sleeve 61. The sliding sleeve 61 can effectively increase the contact area between the main body base 1 and the stud bolt 2, thereby improving the connection stability between the stud bolt 2 and the main body base 1.

[0031] The working principle of the present technical solution is as follows: when the rubber sheet 3 contacts the belt, the portion where the rubber sheet 3 and the belt meet forms a serrated structure due to the slots 31, which can more effectively cut into the material, especially the bulky and sticky material, thereby preventing the material from causing the rubber sheet 3 to deform as a whole. At the same time, the serrated structure also increases the contact area between the rubber sheet and the material, thereby improving the scraping effect. After the temperature of the rubber sheet 3 rises due to long-term friction with the belt, the heat in the rubber sheet 3 can be discharged to the outside through the ventilation holes 11 to avoid heat accumulation. When the end of the rubber sheet 3 is worn and shortened, the spring 62 releases part of the elastic potential energy to push the main body base 1 and drive the rubber sheet 3 to move upward, thereby enabling the rubber sheet 3 to effectively scrape off the attachments on the belt.

[0032] In addition, a plurality of through holes are formed in the supporting channel steel of the present invention for dissipating the heat generated by the friction between the rubber plate and the belt. These through holes are arranged corresponding to or staggered with the notch positions of the rubber plate to maximize the heat dissipation effect. In a high-temperature environment, the design of the through holes can significantly reduce the temperature of the rubber plate and prevent it from reducing the scraping effect and service life due to thermal expansion.
