Description

Technical Field

[0001] The utility model relates to the field related to graphite processing, and more specifically to a graphite dust cover. Background Art

[0002] In the graphite processing, crushing is the first processing step. When the graphite raw materials enter the crusher for crushing, the feed port of the crusher will produce a lot of dust due to the crushing of graphite. A lot of dust not only makes the workshop environment worse, but also causes damage to the workers' health. Utility Model Content

[0003] The main technical problem solved by the utility model is to provide a graphite dust cover. The device can effectively seal the crusher feed port without affecting the feed, thereby solving the problem of dust flying out of the feed port.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A graphite dust cover comprises an outer frame, characterized in that: a dust door is installed on the outer frame, there are multiple dust doors, and a control component is installed on the dust door;

[0006] The dustproof door includes a triangular top, a connecting piece, a door panel, an axle rod and a spring. Connecting pieces are fixedly installed at both ends of the triangular top, a axle rod is fixedly installed between the two connecting pieces, a spring is mounted on the axle rod, the door panel is hinged between the two connecting pieces, the outwardly extending parts of the two broken ends of the spring are against the door panel, the connecting piece is slidably installed in a slide groove set on the outer frame, and the control component is installed in a through hole set in the connecting piece.

[0007] As a further optimization of the technical solution, the utility model provides a graphite dust cover, wherein the control assembly includes a connecting rod, two springs and a handle. The connecting rod passes through a through hole provided in the connecting piece. One end of the connecting rod passes through an outer frame and is fixedly installed with a handle. A plug is provided at the other end of the connecting rod. Two springs are provided between two adjacent connecting pieces and are sleeved on the connecting rod.

[0008] As a further optimization of the technical solution, the utility model provides a graphite dust cover, wherein the connecting rod is provided with a strip-shaped through hole, and a retaining bar is rotatably installed in the strip-shaped through hole.

[0009] As a further optimization of the technical solution, the outer surface of the baffle strip of the graphite dust cover of the utility model is provided with a rubber layer for increasing friction.

[0010] As a further optimization of the technical solution, the outer surface of the handle of the graphite dust cover of the utility model is provided with a rubber layer for increasing friction.

[0011] The beneficial effects of the graphite dust cover of the utility model are:

[0012] 1. When in use, the device is directly covered at the feeding port of the graphite crusher. When feeding, the graphite raw materials fall on the dustproof door. Relying on gravity, the graphite raw materials press down the two adjacent door panels and fall into the crusher below. At the same time, the door panels are closed under the action of spring 1 to ensure that they are sealed in the first time and the dust generated by the crushing will not fly out, thus achieving the purpose of not affecting the feeding and ensuring that the dust will not fly out.

[0013] 2. When the feed opening needs to be enlarged, pull the connecting rod through the handle to make the plug squeeze the connecting piece, thereby shrinking the multiple dust-proof doors to enlarge the feed opening. Rotate the baffle 90° to make the baffle stuck on the outer surface of the outer frame, so that the multiple dust-proof doors always remain in a retracted state. When restoration is needed, restore the position of the baffle, and spring 2 will unfold the multiple dust-proof doors to their original state. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Embodiment 2: Based on the embodiment 1, the following is described. Figure 7 As shown, a bar-shaped through hole 311 is provided on the connecting rod 31, and a baffle 34 is rotatably installed in the bar-shaped through hole 311. The outer surface of the baffle 34 is provided with a rubber layer for increasing friction, so that the baffle 34 will not unfold due to vibration when it is retracted into the bar-shaped through hole 311.

[0025] The working principle of the graphite dust cover of the present invention is as follows:

[0026] When in use, the device is directly covered at the feeding port of the graphite crusher. When feeding, the graphite raw material falls on the dustproof door 2. Relying on gravity, the graphite raw material presses down the two adjacent door panels 23 and falls into the crusher below. At the same time, the door panels 23 are closed under the action of the spring 25 to ensure that they are sealed in the first time and that the dust generated by the crushing will not fly out, thereby achieving the purpose of not affecting the feeding and ensuring that the dust will not fly out.

[0027] When the feed opening needs to be enlarged, the connecting rod 31 is pulled by the handle 33, so that the plug 35 squeezes the connecting piece 22, thereby shrinking the multiple dustproof doors 2 to enlarge the feed opening, and the baffle 34 is rotated 90° so that the baffle 34 can be stuck on the outer surface of the outer frame 1, so that the multiple dustproof doors 2 always remain in a retracted state. When restoration is needed, the position of the baffle 34 is restored, and the spring 2 32 will expand the multiple dustproof doors 2 and restore them to their original state.

[0028] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the protection scope of the present invention.
