The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
A conveyor belt having a negative pressure sweeping function according to an embodiment of the present invention is described below with reference to fig. 1 to 4.
The conveyor belt with the negative pressure cleaning function according to the embodiment of the invention comprises a conveyor belt 100, a scraper 200 and an absorber 300. The conveyor belt 100 is suitable for conveying materials, the scraper 200 is installed at the end of the conveyor belt 100 and attached to the surface of the conveyor belt 100, openings are formed in the upper end and the lower end of the adsorber 300, the openings are perpendicular to the moving direction of the conveyor belt 100 and installed below the conveyor belt 100, a certain gap is reserved between the upper opening of the adsorber 300 and the conveyor belt 100, an air suction pipeline 310 is arranged on the side wall of the adsorber 300 and communicated with an air pump, and a filter screen 320 is arranged on the air suction pipeline 310. For example, referring to fig. 1, the end of the conveyor belt 100 refers to a position where the conveyor belt 100 moves in reverse after transporting the material to a designated position, for example, the right end as viewed in fig. 1. The flights 200 typically engage the belt 100 through resilient adjustment members. Since the blade 200 is easily worn, an elastic adjustment member is required to adjust the position of the blade 200, thereby extending the life span of the blade 200. In this embodiment, the scraper 200 is arranged in a tangential direction of the conveyor belt 100,
the adsorbers 300 are generally elongated and have a length greater than the width of the conveyor belt 100 to ensure complete cleaning of the conveyor belt 100. The adsorber 300 is disposed below the conveyor belt 100 and is mainly used for adsorbing dust remaining on the conveyor belt 100, and for larger particles, even if the scraper 200 is not scraped off in time, the lower surface of the conveyor belt 100 may fall due to gravity, and at this time, the remaining dust is mainly. The adsorber 300 sucks the dust remaining on the conveyor belt 100 from the upper port of the adsorber 300 by reducing the air pressure, and discharges the dust through the lower port of the adsorber 300. Specifically, the adsorber 300 is connected to the air pump through the air suction pipe 310, and the air pressure in the adsorber 300 can be reduced when the air pump works, and in order to prevent dust from entering the air pump through the air suction pipe 310 and affecting the work of the air pump, the air suction pipe 310 is provided with the filter screen 320 to prevent dust from entering the air pump.
In some embodiments of the present invention, the suction pipe 310 is disposed at one end of the adsorber 300, the filter screen 320 is cylindrical and disposed parallel to the conveyor belt 100, and the inside of the filter screen 320 communicates with the suction pipe 310. For example, referring to fig. 2, the screen 320 is rolled into a cylinder shape, and the suction duct 310 is connected to the inside of the screen 320. The rolling of the screen 320 into a cylindrical shape is mainly for uniformly distributing the negative pressure in the width direction of the conveyor belt 100 and sufficiently cleaning the conveyor belt 100.
In some embodiments of the present invention, an end of the filter screen 320 communicating with the air suction duct 310 is provided with a connection seat 321, and the connection seat 321 is fixed to the air suction duct 310 by a bolt so that the filter screen 320 and the air suction duct 310 can be fixedly communicated. For example, referring to fig. 2, the air suction duct 310, the connection seat 321, and the filter screen 320 are sequentially connected, wherein the filter screen 320 and the connection seat 321 are generally designed to be fixedly connected, and the connection seat 321 is provided with a hole communicated with the inside of the filter screen 320 and correspondingly connected with the air suction duct 310 when being connected. Connect fixedly through connecting seat 321, conveniently dismantle the change, the leakproofness is better simultaneously. The filter screen 320 is made of high-density breathable fiber cloth, so that the filter effect can be guaranteed, and the filter screen is convenient to process into a cylinder shape.
In some embodiments of the present invention, a sealing rubber gasket 322 is disposed between the connection seat 321 and the suction pipe 310, for example, referring to fig. 2, the sealing rubber gasket 322 is sandwiched between the connection seat 321 and the suction pipe 310, and in particular, an opening should be disposed in the middle of the sealing rubber gasket 322 so as not to block the suction pipe 310. The sealing rubber pad 322 is mainly used for enabling the connection between the connecting seat 321 and the air suction pipeline 310 to be tighter, and preventing the air leakage from occurring and reducing the adsorption force.
In some embodiments of the present invention, the suction pipe 310 is disposed on only one side wall of the adsorber 300, and one end of the filter screen 320 close to the suction pipe 310 communicates with the suction pipe 310 and the other end far from the suction pipe 310 is closed. For example, referring to fig. 2, the suction line 310 is disposed at the left end of the adsorber 300. Because the dust amount on the conveyor belt 100 is usually not much and the adhesive force is weak, only one air suction pipeline 310 needs to be arranged to meet the cleaning requirement on the conveyor belt 100, so that the pipeline wiring can be simplified, and the cost is reduced. Certainly, in some occasions where dust adheres firmly, the suction pipes 310 can be arranged at both ends to increase the negative pressure, so that the adsorption effect is better.
In some embodiments of the invention, the end of the adsorber 300 remote from the suction line 310 is provided with a bracket 330 for supporting the screen 320. Because only one end of the filter screen 320 is connected and the other end is not fixed, the filter screen is easy to bend and deform under stress after being placed for a long time, and the service life of the equipment is shortened. Therefore, a bracket 330 is provided at the other end of the screen 320 to support the screen 320 and prevent the screen 320 from being deformed by its own weight.
In some embodiments of the present invention, a screen frame 340 is disposed in the screen 320 to prevent the filter cartridge from deforming due to a large adsorption pressure. For example, referring to fig. 4, the screen holder 340 is mainly used to support the screen 320 and prevent the screen 320 from deforming due to a large suction pressure. In this embodiment, the screen frame 340 is supported by four support rods 341 along the length of the screen 320, and support rings 342 corresponding to the inner shape of the screen 320 are provided at both ends and the middle portion. The strainer holder 340 may have various structures, and only the inside of the strainer 320 needs to be ventilated and the strainer 320 can be deformed, for example, the strainer 320 is filled with cotton or iron wires, which can also achieve the corresponding effect.
In some embodiments of the present invention, the adsorber 300 has an inverted trapezoidal cross-section with a top side parallel to the conveyor belt 100, a bottom side disposed horizontally, and a side inclined from bottom to top toward the direction of movement of the conveyor belt 100 to enlarge the upper opening of the adsorber 300. For example, referring to fig. 4, the left side of the adsorber 300 is tilted outward to enlarge the upper opening of the adsorber 300, so that the adsorption surface of the adsorber 300 is enlarged, and dust having a larger area can be adsorbed, thereby improving the adsorption effect.
In some embodiments of the present invention, a rubber baffle 350 is disposed on an inclined side of the adsorber 300. For example, referring to fig. 4, the upper end of the rubber dam 350 is attached to the conveyor belt 100, so that the rubber dam is prevented from being attached to the conveyor belt 100 again when the dust of the filter screen 320 is blown out, and the surface of the conveyor belt 100 can be scraped again, thereby sufficiently cleaning the conveyor belt 100.
The working principle of the invention is as follows: the powder of adhesion on the conveyer belt 100 is earlier tentatively scraped through scraper blade 200, then passes through adsorber 300, and adsorber 300 reduces the atmospheric pressure of filter screen 320 department through the air pump and forms the negative pressure to adsorb the powder of adhesion on conveyer belt 100, adsorber 300 is after extracting a period, and the filter screen 320 surface can be covered with to the dust, and at this moment, the air pump can reverse outside blow off the air, makes the dust that adheres to on filter screen 320 surface drop, and discharges from adsorber 300 end opening, thereby realizes adsorbing the effect of cleaning.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
