[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] Reference Figure 1 As shown in the embodiment of this application, an inclined calcined petroleum coke dust removal device is disclosed, comprising: a housing 1, which is hollow inside; a first hopper 21, which is disposed on the housing 1 and connects to the interior of the housing 1 for receiving calcined petroleum coke; a plurality of sliding plates 3, which are inclined to the horizontal plane and disposed inside the housing 1 for guiding the calcined petroleum coke to slide; wherein, along the direction of gravity from top to bottom, the plurality of sliding plates 3 are staggered at fixed height intervals to form a return channel for the sliding of calcined petroleum coke; a plurality of negative pressure components are disposed on both sides of the housing 1, between any two adjacent sliding plates 3, for providing negative pressure to the falling calcined petroleum coke to suck away dust; a second hopper 22, which is disposed below the sliding plates 3; and a belt conveyor 4, which is disposed below the second hopper 22 for receiving and transporting the calcined petroleum coke.

[0022] In practical use, calcined petroleum coke is fed into the housing 1 through the first hopper 21. The calcined petroleum coke is spread flat on the slide plate 3, which disperses the calcined petroleum coke. The slide plate 3 is set at an inclination to the horizontal plane in the housing 1. Under the action of gravity, the calcined petroleum coke slides along the slide plate 3. As the calcined petroleum coke slides from one slide plate 3 to the next slide plate 3, the negative pressure component provides negative pressure to the calcined petroleum coke, sucking away the particulate dust in the calcined petroleum coke, thus completing the dust removal work of the calcined petroleum coke.

[0023] In this invention, the inclined sliding plate 3 guides the calcined petroleum coke to slide along the return channel inside the box 1 under the action of gravity. A negative pressure component is provided on the side where the calcined petroleum coke falls, which can provide negative pressure to the falling calcined petroleum coke, suck away the particulate dust in the calcined petroleum coke, perform dust removal operation on the calcined petroleum coke, reduce dust flying during subsequent transportation, and reduce the harm of dust to on-site personnel.

[0024] Preferably, one end of the slide plate 3 is connected to the inner wall of the box 1, and the other end of the slide plate 3 is spaced at a fixed distance from the inner wall of the box 1, so that the calcined petroleum coke can fall.

[0025] It is worth mentioning that the slide plate 3 is made of stainless steel, and the smooth surface of stainless steel prevents petroleum coke from accumulating on the slide plate 3 after calcination.

[0026] Preferably, a welded support rod can be installed under the slide plate 3 to support the slide plate 3 on the inner wall of the box 1.

[0027] Preferably, a vibration motor can be installed below the slide plate 3 to drive the slide plate 3 to vibrate, thereby preventing the calcined petroleum coke from accumulating on the slide plate 3.

[0028] Reference Figure 2 , Figure 4 and Figure 5 As shown, the device further includes: a first discharge plate 51, fixedly disposed inside the first hopper 21; a second discharge plate 52, slidably disposed inside the first hopper 21, located below the first discharge plate 51; a plurality of first discharge slots 53, spaced at fixed intervals, opened on the first discharge plate 51; a plurality of second discharge slots 54, spaced at fixed intervals, opened on the second discharge plate 52; and a telescopic component 55, the main body of which is fixedly installed on the outer wall of the housing 1, and the piston rod of the telescopic component 55 is connected to the second discharge plate 52.

[0029] In practical use, the first discharge plate 51 blocks the first hopper 21, and the second discharge plate 52 is stacked below the first discharge plate 51; the telescopic component 55 is activated periodically, and the piston rod of the telescopic component 55 performs one extension and retraction stroke, so that the second discharge chute 54 and the first discharge chute 53 are periodically connected; when the first discharge chute 53 and the second discharge chute 54 are connected, under the action of gravity, the calcined petroleum coke in the first hopper 21 can be sent into the box 1; when the first discharge chute 53 and the second discharge chute 54 are staggered, the first hopper 21 can be blocked.

[0030] In this embodiment, by setting the first discharge plate 51, the second discharge plate 52 and the telescopic component 55, the slide plate 3 can be fed intermittently, preventing too much calcined petroleum coke from entering the box 1 at one time, preventing the thickness of calcined petroleum coke on the slide plate 3 from being too large, and improving the negative pressure dust removal efficiency of the negative pressure component.

[0031] It is worth mentioning that the telescopic component 55 is a cylinder; when the piston rod of the cylinder is in the extended state, the first discharge chute 53 and the second discharge chute 54 are staggered and block the first hopper 21 to prevent the calcined petroleum coke from being discharged; when the piston rod of the cylinder is in the telescopic state, the first discharge chute 53 and the second discharge chute 54 are connected, and the calcined petroleum coke can fall from the first hopper 21 into the box 1.

[0032] Reference Figure 3 As shown, the negative pressure assembly includes: a negative pressure pump (not shown) for providing negative pressure; a dust removal pipe 61, one end of which is connected to the interior of the housing 1 and the other end of which is connected to the negative pressure pump; and a filter bag 62, which is disposed inside the dust removal pipe 61 for intercepting particulate dust.

[0033] It is understandable that a negative pressure pump can be a vacuum pump.

[0034] The negative pressure pump provides negative pressure to the dust removal pipe 61, which in turn provides negative pressure to the falling calcined petroleum coke, drawing the particulate dust in the calcined petroleum coke into the dust removal pipe 61, and then intercepting the particulate dust through the filter bag 62.

[0035] It is understandable that the suction force of the dust removal pipe 61 on the calcined petroleum coke can be adjusted by controlling the power of the negative pressure pump, so as to prevent the petroleum coke from being sucked into the dust removal pipe 61.

[0036] Specifically, the device also includes: a nut 63, which is welded and fixed to the outer wall of the housing 1; a flange 64, which is welded and fixed to the dust removal pipe 61; and a first mounting screw 65, which can pass through the flange 64 and be installed on the nut 63 by threaded connection.

[0037] In this embodiment, the dust removal pipe 61 is detachably installed on the housing 1 by the first mounting screw 65; this facilitates the disassembly and maintenance of the dust removal pipe and the filter bag 62 by the staff.

[0038] Specifically, the device also includes: a mounting frame 66, on which the filter bag 62 is mounted; a fixing frame 67, which is welded and fixed inside the dust removal pipe fitting 61; and a second mounting screw 68, which can pass through the fixing frame 67 and be installed on the fixing frame 67 by threaded connection.

[0039] It is worth mentioning that the cloth bag 62 can be glued to the mounting frame 66; the mounting frame 66 can be detachably installed on the fixed frame 67 by the second mounting screw 68, which makes it easy for staff to disassemble and assemble the mounting frame 66 and to clean and maintain the cloth bag 62.
