Description

Technical field:

[0001] The utility model relates to the technical field of air suspension conveyors, in particular to a novel air suspension belt conveyor device. Background technology:

[0002] Air suspension belt conveyor is a new type of conveying equipment. At the beginning of the 21st century, air suspension conveyor entered China's grain storage and transportation system. After more than ten years of use, the excellent characteristics of air suspension conveyor have been fully demonstrated. Now it has been widely used in mining, coal, metallurgy, building materials, grain, chemical industry, port and other industries. It uses air film to support the conveyor belt and is used to convey density of 0.5~2.5t / m 3 For loose materials such as block, granular, powder, etc., it replaces the roller of the roller belt conveyor with an air chamber with holes. When the air source provides air with a certain pressure and flow rate to the air chamber, the air in the air chamber overflows through the air flotation holes on the disc groove (the arc-shaped groove on the upper part of the air chamber), forming a layer of air film with a certain pressure between the conveyor belt and the disc groove to support the conveyor belt and the material on it; in actual application, such as Figure 5 As shown, after the compressed air provides the conveyor belt with upward undulating power, it is discharged from the outer edges of both sides of the conveyor belt. If there are more materials on the conveyor belt, the discharged airflow will easily lift the powdered materials or small particles on the conveyor belt, resulting in serious dust in the conveyor cavity. Although this part of the dust is purified by the air filter, it will lead to a short service life of the air filter, and the air filter element needs to be replaced more frequently, affecting production efficiency. At the same time, when the air suspension conveyor is fed, it is easy for granular materials to splash into the space between the conveyor belt and the disc groove, causing the air flotation holes to be blocked. If the air flotation holes are blocked more, it will cause uneven airflow distribution, which will cause the conveyor belt to deviate, which is difficult to detect in time and prone to material spillage accidents. Utility model content:

[0003] The utility model aims to provide a novel air suspension belt conveyor device to solve the technical problems in the prior art that the amount of dust in the inner cavity of the air suspension belt conveyor is too large, resulting in a short service life of the air filter, requiring frequent replacement of the filter element, and affecting work efficiency.

[0004] The content of the utility model: A novel air suspension belt conveyor device, which includes a body, a disc groove and a conveyor belt installed in the body, an air filter and a fan assembly installed on the body, an inverted V-shaped air guide plate is arranged above the conveyor belt, the end of the air guide plate extends to above the outer edge of the conveyor belt, the distance between the end of the air guide plate and the outer edge of the conveyor belt is 20 mm, and the air guide plate is used to guide the compressed air discharged from the bottom of the conveyor belt to the air filter.

[0005] Furthermore, a conveyor belt position warning device is installed on the wind guide plate, and the conveyor belt position warning device is used to warn the suspension height and suspension position of the conveyor belt.

[0006] Furthermore, the conveyor belt position warning device includes a proximity sensor, the proximity sensor is electrically connected to the PLC controller, and the PLC controller is electrically connected to the alarm.

[0007] Furthermore, a plurality of dust shields are evenly distributed along the length direction on the air guide plate, and ventilation holes are provided on the dust shields.

[0008] Furthermore, the ventilation holes on the adjacent dust shield plates are arranged in an up-and-down staggered manner.

[0010] Furthermore, a rubber plug is plugged in the air flotation hole, and the air flotation hole is arranged in the rubber plug.

[0011] The beneficial effects of the utility model are as follows: the utility model designs an air guide plate above the conveyor belt, which can guide the airflow to flow more upwards, prevent excessive airflow from blowing the materials on the conveyor belt, thereby avoiding the generation of large dust, reducing the filtering pressure of the air filter, extending the service life, and greatly increasing the filter element replacement cycle, thereby improving the overall working efficiency of the air suspension conveyor. At the same time, a conveyor belt position early warning device is designed to timely detect conveyor belt deviation and ensure safe and smooth material transportation. Description of the drawings:

[0017] In the figure, the machine body 1, the disc slot 2, the conveyor belt 3, the air filter 4, the fan assembly 5, the air guide plate 6, the proximity sensor 8, the PLC controller 9, the alarm 10, the dust shield 7, the ventilation hole 11, the material storage slot 12, the air flotation hole 13, and the rubber plug 14. Specific implementation method:

[0018] Embodiment 1:

[0019] like Figure 1 As shown, a novel air suspension belt conveyor device includes a body 1, a disc groove 2 and a conveyor belt 3 are installed in the body 1, an air filter 4 and a fan assembly 5 are installed on the body 1, and an inverted V-shaped air guide plate 6 is arranged above the conveyor belt 3. The end of the air guide plate 6 extends to above the outer edge of the conveyor belt 3, and the distance between the end of the air guide plate 6 and the outer edge of the conveyor belt 3 is 20 mm. The air guide plate 6 is used to guide the compressed air discharged from the bottom of the conveyor belt 3 to the air filter 4.

[0020] like Figure 2 It is shown that a conveyor belt position warning device is installed on the air guide plate 6, and the conveyor belt position warning device is used to warn the suspension height and suspension position of the conveyor belt 3; the conveyor belt position warning device includes a proximity sensor 8, and the proximity sensor 8 is electrically connected to the PLC controller 9, and the PLC controller 9 is electrically connected to the alarm 10.

[0021] like Figure 3 As shown, in order to further prevent excessive dust particles from entering the air filter 4 (usually, an air suspension conveyor is only equipped with one fan assembly 5 and one set of air filters 4), a plurality of dust shields 7 are evenly installed along the length direction on the air guide plate 6, and ventilation holes 11 are opened on the dust shields 7; the ventilation holes 11 on adjacent dust shields 7 are staggered up and down.

[0022] During specific operation, the air flow is discharged from both sides of the conveyor belt 3. Since the air guide plate 6 flows more upward, the horizontal blowing is reduced, thereby reducing the dust of the material. At the same time, since the air flow and dust particles will flow for a distance before entering the air filter 4, the dust shield plate 7 is designed to further capture dust particles, thereby further reducing the dust particles entering the air filter 4, thereby increasing the service life of the air filter 4 and reducing the frequency of filter element replacement.

During specific operation, even if small particle materials block the air flotation hole 13, the particle materials will be temporarily stored in the material storage groove 12 to prevent the materials from scratching the conveyor belt 3.
