Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belt cleaning devices, in particular to a belt return cleaning device. Background Art

[0002] In the metallurgical industry, the frequent use of belt transportation, also known as conveyor belt transportation, makes the phenomenon of dust leakage particularly prominent. According to current environmental protection requirements, it is particularly important to take effective measures to reduce the material spillage and dust leakage during belt transportation. Usually, a material guide trough is installed at the material receiving point of the belt, and the use of dust removal facilities can further reduce the generation of dust. However, although the combination of the material guide trough and the dust removal facilities has greatly reduced the generation of dust, there are still some dust problems that have not been completely solved. This part of the dust mainly comes from the adhesion materials carried by the belt during the return process. When these adhesion materials rub against the rollers, tiny particles will be generated and then drift into the air, causing dust leakage. In this regard, the present application specifically proposes a belt return blowing device. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a belt return blowing device, which solves the problem. The technical solution is as follows: it includes a frame, a conveyor belt is installed on the frame, and is characterized in that a support frame is arranged below the conveyor belt, an adjustment bracket is arranged on the support frame, an upper end of the adjustment bracket is fixedly connected to an air knife, and the air outlet of the air knife faces the lower surface of the conveyor belt, a high-pressure fan is arranged on one side of the frame, the outlet end of the high-pressure fan is fixedly connected to the inlet end of a hose, and the outlet end of the hose is fixedly connected to the inlet end of the air knife;

[0004] The adjusting bracket includes a lower support plate fixedly connected to the support frame, the lower support plate is fixedly connected to two vertical rods arranged in a front-to-rear correspondence, the upper ends of the two vertical rods are fixedly connected to the upper support plate, the upper support plate and the lower support plate are rotatably connected at the opposite ends, the screw is located between the two vertical rods, the screw is threadedly connected to the middle part of the adjusting rod, the front and rear ends of the adjusting rod are respectively slidably connected to the two vertical rods, the adjusting rod is fixedly connected to two connecting rods arranged in a front-to-rear correspondence, the two connecting rods are fixedly connected to the lower end of the wind knife, and the upper support plate is fixedly connected to a motor for driving the screw.

[0005] Preferably, a bracket fixedly connected to the high-pressure blower is arranged on one side of the frame.

[0006] Preferably, the adjusting rod is integrally provided with a driven sleeve threadedly connected to the lead screw, and the adjusting rod is integrally provided with a guide sleeve slidably connected to the vertical rod.

[0007] Preferably, the support frame is fixedly connected to a chute corresponding to the air knife.

[0008] The beneficial effects of the utility model are:

[0009] 1. When the present application is in use, the wind knife is arranged below the belt, i.e., the conveyor belt, and the air outlet of the wind knife corresponds to the lower side of the conveyor belt, and then under the action of the high-pressure fan, the high-pressure airflow can enter the wind knife through the hose and be released from the air outlet of the wind knife. The high-pressure airflow released from the air outlet of the wind knife is like a scraper, which can be used to sweep the return part on the lower side of the conveyor belt when transporting materials, and then the sticky materials on the conveyor belt can be swept and cleaned to prevent the sticky materials from rubbing against the rollers and breaking and forming dust. The large particles of materials blown down fall into the chute below for centralized cleaning.

[0010] 2. Furthermore, the present application is provided with an adjustment bracket, by which the distance between the air knife outlet and the conveyor belt can be changed, and thus the intensity of the blowing can be changed to adapt to the cleaning of different materials.

[0017] The following is combined with Figure 1-4 The specific implementation methods of the present invention are further described in detail.

[0018] In the first embodiment, the technical solution is that when the present application is in use, the wind knife 5 is arranged below the belt, i.e., the conveyor belt 2, and the air outlet of the wind knife 5 corresponds to the lower side of the conveyor belt 2, and then under the action of the high-pressure blower 6, the high-pressure airflow can enter the wind knife 5 through the hose 7 and be released from the air outlet of the wind knife 5. The high-pressure airflow released from the air outlet of the wind knife 5 is like a scraper, which can be used to sweep the return part of the lower side of the conveyor belt 2 when the material is transported, and then the adhering materials on the conveyor belt 2 can be swept and cleaned to prevent the adhering materials from rubbing against the rollers and breaking and forming dust. The large particles of materials blown down fall into the chute 18 below for centralized cleaning. Furthermore, the present application is arranged with an adjustment bracket 4, by which the distance between the air outlet of the wind knife 5 and the conveyor belt 2 can be changed, and then the intensity of the blowing can be changed to adapt to the cleaning of different materials, to prevent the adhering materials on the conveyor belt 2 from being blown into pieces and generating dust.

[0019] Example 2, based on Example 1, when the present application is in use, the frame 1, support frame 3 and bracket 15 are cast and fixed in a suitable position in the workshop, thereby providing an installation position for related components. During use, the present application uses an industrial air knife 5, which can release a high-pressure airflow like a scraper under the action of the high-pressure blower 6, thereby powerfully blowing the return part of the lower side of the conveyor belt 2. When it is necessary to change the distance between the air outlet of the air knife 5 and the conveyor belt 2, the motor 14 can be started normally. The forward rotation of the motor 14 will drive the screw 11 connected between the upper support plate 10 and the lower support plate 8 to rotate forward. The forward rotation of the screw will act on the adjustment rod 12 through the driven sleeve 16, and the adjustment rod 12 is restricted by the sliding connection between the guide sleeve 17 and the vertical rod 9. Therefore, the forward rotation of the screw 11 will drive the adjustment rod 12 to move upward, and then the connecting rod 13 and the air knife 5 will move upward synchronously; accordingly, starting the motor 14 in reverse will drive the screw 11 to reverse, and then drive the air knife 5 to move downward, and then the air knife 5 can be adjusted.
