Description

Technical Field

[0001] This utility model relates to the field of manganese ball screening technology, specifically a manganese ball screening dust removal device. Background Technology

[0002] The screening process for manganese balls generates a large amount of dust. This dust not only affects the health of operators but also pollutes the surrounding working environment and can even clog equipment, impacting screening efficiency. Existing technologies use dust removal devices to reduce dust dispersion and improve the working environment. The dust collection port of existing dust removal devices is usually located at the discharge port of the screening equipment to prevent dust from spreading outwards after the manganese balls are screened. However, the design of existing dust removal devices fails to fully cover all dust generation points during the screening process, especially the dust control during the feeding stage, which is significantly inadequate. A large amount of dust still diffuses outwards during the feeding stage, affecting the health of operators and polluting the surrounding environment. Utility Model Content

[0003] This invention provides a dust removal device for manganese ball screening, which can solve the problem that a large amount of dust still spreads outward during the feeding stage, affecting the health of operators and polluting the surrounding environment.

[0004] This application provides the following technical solution:

[0005] A manganese ball screening dust removal device includes a feeding hopper, the discharge port at the bottom of the feeding hopper corresponding to the feeding port at the top of the screening machine, a dust removal hood above the feeding hopper, the dust removal hood being connected to a dust collector via a dust removal pipe, a dustproof curtain on the dust removal hood extending downward to the outer periphery of the feeding hopper, a first opening on the feeding hopper, and a second opening on the dustproof curtain, the first opening and the second opening cooperating to form a feeding port.

[0006] Beneficial effects: A dust collector hood connected to the dust collector is installed above the feed hopper to promptly remove dust generated during the feeding stage. Simultaneously, the dust curtain extends downwards to enclose the feed hopper, forming a physical barrier that effectively reduces dust diffusion and minimizes environmental pollution. An inlet is located between the feed hopper and the dust curtain, maintaining a relatively enclosed feeding environment without affecting normal feeding, enhancing dust removal efficiency, and preventing external impurities from entering the feed hopper.

[0007] Furthermore, a support is provided below the feed hopper, and multiple support rods are provided between the feed hopper and the support.

[0008] Beneficial effects: The rigid support system of the bracket and support rod evenly distributes the weight of the feed hopper to the ground or installation foundation, preventing the feed hopper from tilting, deforming or even collapsing due to material accumulation or equipment vibration, thus ensuring the safe operation of the equipment.

[0009] Furthermore, the upper end of the feed hopper is a cylindrical tube, and the lower end is a conical tube. The cylindrical tube at the upper end of the feed hopper is provided with an upwardly extending baffle, and a first opening is provided on one side of the baffle.

[0010] Beneficial effects: The upper cylindrical section provides a large feeding space, facilitating rapid material pouring, while the lower conical section guides the material towards the discharge port, using gravity to accelerate its descent and reduce the risk of material retention and blockage. When the height of the upper cylindrical section of the feed hopper is low, a baffle can be used to increase the height of the cylindrical section, facilitating its integration with the dust curtain and effectively preventing dust from spreading outwards.

[0011] Furthermore, the dustproof curtain includes a first curtain fabric disposed directly below the dustproof cover, a second curtain fabric disposed on one side of the first curtain fabric, the second curtain fabric being fixed to one side of the dustproof cover by a support rod, and a second opening being provided on the second curtain fabric.

[0012] Beneficial effects: The first and second curtains form a semi-enclosed space with the outer perimeter of the feed hopper, which makes the negative pressure of the dust collector more concentrated, quickly removes dust, and prevents it from spreading.

[0013] Furthermore, the dust removal pipe includes a main dust removal pipe, on which a first pipe and a second pipe are provided. The first pipe is connected to the dust removal hood, and the second pipe is connected to two branch pipes through a first flexible hose. The two branch pipes are respectively set at the two discharge ports of the screening machine. A branch pipe is provided on the second pipe, and the branch pipe is set at the feed port at the top of the screening machine through a second flexible hose.

[0014] Beneficial effects: It fully covers the dust generation points in the screening process, improves dust removal efficiency, and protects the surrounding environment. Attached Figure Description

[0018] Example 1

[0019] like Figure 1As shown, the manganese ball screening dust removal device includes a feed hopper 1. The top of the feed hopper 1 is open, and the bottom of the feed hopper 1 is a discharge port. The upper end of the feed hopper 1 is a cylindrical tube, and the lower end is a conical tube. A support 3 is provided below the feed hopper 1 to provide stable support for the feed hopper 1. Multiple support rods 4 are provided between the feed hopper 1 and the support 3, and the support rods 4 are fixedly connected to the feed hopper 1 and the support 3 by welding. The discharge port at the bottom of the feed hopper 1 passes through the support 3 and corresponds to the feed port at the top of the screening machine 2. A dust removal hood 5 is provided above the feed hopper 1. The dust removal hood 5 is connected to an industrial dust collector located outside the workshop through a dust removal pipe 6. A dust curtain 8 is provided on the dust removal hood 5, which extends downward to the outer periphery of the feed hopper 1. A first opening 91 is provided on the side wall of the upper cylindrical tube of the feed hopper 1, and a second opening 92 is provided on the dust curtain 8. The first opening 91 and the second opening 92 cooperate to form a feed inlet 9.

[0020] The dustproof curtain 8 includes a first curtain 81 positioned directly below the dustproof cover. A second curtain 82 extending outwards is located on one side of the first curtain 81. The second curtain 82 is fixed to one side of the dustproof cover by a support rod and has a second opening 92. The first curtain 81 and the second curtain 82 are connected at their upper ends and separated at their lower ends, allowing the second curtain 82 to be adjusted up and down as needed via the support rod, thereby adjusting the size of the inlet 9. The dustproof curtain 8 can be made of flexible, wear-resistant materials, such as rubber curtains or PVC-coated fabric.

[0021] The dust collection pipe 6 is supported on the workshop ceiling by a hanger. The dust collection pipe 6 includes a main dust collection pipe 61, which connects to the dust collector. The main dust collection pipe 61 has a horizontally extending first pipe 62 and a vertically extending second pipe 63. The first pipe 62 connects to the dust collection hood 5. The second pipe 63 is connected to two branch pipes via a first flexible hose 65, which are respectively located at the two discharge ports of the screening machine. A branch pipe 64 is provided on the second pipe 63, and the branch pipe 64 is located at the feed inlet at the top of the screening machine 2 via a second flexible hose 66. The diameter of the first pipe 61 is larger than the diameter of the second pipe 62.

[0022] The usage method is as follows:

[0023] In operation, a forklift moves the transfer hopper containing the material, allowing it to enter through the inlet 9 and move above the feed hopper 1. The outlet below the transfer hopper is then opened, allowing the material to move from the transfer hopper into the feed hopper 1. Alternatively, a traveling crane can move the transfer hopper and tilt it to transfer the material into the feed hopper 1. During the screening process, the material enters the screening machine 2 through the feed hopper 1 for screening. Dust is removed from the feed hopper 1 and the screening machine 2 using a dust collector hood 5 and a dust collector pipe 6, protecting the surrounding environment.

[0024] Example 2

[0025] The difference between this embodiment and the previous embodiment is that the upper cylindrical section of the feed hopper 1 is provided with an upwardly extending baffle, and a first opening 91 is provided on one side of the baffle. When the height of the upper cylindrical section of the feed hopper 1 is low, the height of the cylindrical section can be increased by the baffle.
