Description

Technical Field

[0001] The invention belongs to the field of material guide troughs, in particular to a double-sealed material guide trough. Background Art

[0002] The guide chute is mainly used in belt conveyors. Installing the guide chute at the receiving end of the belt conveyor can concentrate the material falling from the hopper to the middle of the conveyor belt before reaching the belt speed, thus preventing the material from spilling out.

[0003] There is an existing related patent, patent number CN201621203235.1, for "non-powered dust suppression double-sealed guide trough", which has the characteristics of "solving the problem of cleaning dust accumulation on the top plate; expanding the closing without increasing the height; the spacing between the conveyor belt bearing rollers makes the conveyor belt wave-shaped and sealed with the protective skirt, thereby improving the conveying efficiency and service life". However, it still has some shortcomings, such as the large width of the guide trough opening and no obstruction, which can easily cause a large amount of dust to move out of the guide trough cavity with the airflow, causing the on-site environment to deteriorate and the dust to exceed the standard, thereby endangering the health of workers and even causing dust explosions. Therefore, a double-sealed guide trough is proposed. Summary of the Invention

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0005] In view of the following technical problems in the existing technology: the opening width of the material guide trough is very large and unobstructed, which easily causes a large amount of dust to move out of the inner cavity of the material guide trough with the airflow, causing the on-site environment to deteriorate and the dust to exceed the standard, thereby endangering the health of workers and even causing dust explosions.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a double-sealed material guide trough, comprising a trough body and a roller support, wherein a support leg is provided on each side of the trough body, a bracket 1 is provided at both ends of the roller support, a roller 2 and a roller 1 are provided on the roller support, and a conveyor belt is movably connected to the roller 2;

[0007] The support leg is provided with a cross arm, and the cross arm is connected to the trough body through a sealing bent plate 1. The front and back sides of the trough body are provided with openings, and an inclined support plate is respectively arranged on both sides of the opening, and the top of the inclined support plate is connected to the sealing bent plate 1, and the bottom end of the inclined support plate is provided with a vertical plate. The sealing bent plate 1, the inclined support plate and the vertical plate form an L-shaped structure, and a dust curtain is arranged in the L-shaped structure. Several mounting holes are opened on the trough body, and an acrylic transparent plate 1 is respectively provided on both sides of the trough body, and the upper part of the acrylic transparent plate 1 is connected to the sealing bent plate 1, and the lower part of the acrylic transparent plate 1 is provided with a bent plate. The trough body and the roller bracket are connected through a bracket 1;

[0008] A plurality of bending cylinders are provided at the top of the trough body, the top of the bending cylinder is connected to an upper sealing cover, a hand wheel is hinged on the bending cylinder, and the hand wheel is threadedly connected to the upper sealing cover.

[0009] As a preferred technical solution for the double-sealed material guide chute, the two sides of the lower side of the support leg are respectively connected to a frame;

[0010] Improve the connection strength between the roller bracket and the support leg.

[0011] As an optimal technical solution for the double-sealed material guide trough, the bolt three is inserted from the top of the roller bracket and connected to the bracket one.

[0012] As an optimal technical solution for the double-sealed material guide trough, the outer side of the bending cylinder is threadedly connected with a bolt 1, and the end of the bolt 1 away from the bending cylinder is threadedly connected to the dust curtain.

[0013] As an optimal technical solution for the double-sealed material guide trough, a holder is provided on the vertical plate, and the bottom end of the holder is connected to an anti-clearing skirt through an aluminum angle plate;

[0014] The holder can adjust the tightness of the anti-clarification skirt. The anti-clarification skirt is installed using the holder and the angle aluminum plate. The anti-clarification skirt blocks liquid splashing on the side.

[0015] The double-sealed material guide trough of the present invention has the beneficial effects of narrowing the opening of the trough body by the inclined support plate and the vertical plate, making the air in the inner cavity of the trough body less likely to be disturbed, thereby reducing the outflow of airflow and preventing dust from entering the inner cavity of the trough body;

[0016] By setting a dustproof curtain at the opening of the trough body, dust is blocked outside the opening of the trough body. The dustproof curtain cooperates with the inclined support plate and the vertical plate to make the internal cavity of the trough body relatively closed, reducing dust from moving out with the airflow.
