[0033] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0035] like Figure 1 , Figure 3 , Figure 7 , Figure 8 and Fig. 9 As shown, in one embodiment, a dust collecting and removing device for petroleum calcined coke production is proposed, and the device comprises:

[0036] The main furnace 1 comprises a furnace drum 101 arranged on the main furnace 1 , an air outlet pipe 102 is fixedly installed on the surface of the furnace drum 101 , and a mounting platform 103 is fixedly installed on the surface of the furnace drum 101 ;

[0037] Switching mechanism 2: comprising a switching turntable 201 rotatably connected to the mounting platform 103, a torsion spring 202 is coaxially fixedly installed inside the switching turntable 201, six rotating cylinders 203 are fixedly installed on the surface of the switching turntable 201, and a filter block 204 is attached to the inner wall of each rotating cylinder 203;

[0038] Energy storage mechanism 3: used to store energy before the switching disk 201 rotates;

[0039] Limiting mechanism 4: used to limit the switching turntable 201 before it rotates.

[0040] In actual application of the embodiment of the present invention, petroleum calcined coke is produced by calcining petroleum coke in the furnace drum 101. At this time, the gas containing dust is generated and enters the switching turntable 201 through the gas outlet pipe 102. Figure 1 As shown, at this time, the gas enters the first station a through the outlet pipe 102. At this time, the filter block 204 at the first station a filters the dust, and the filtered airflow is discharged through the rotating cylinder 203. As the dust gathers on the filter block 204, the weight of the filter block 204 gradually increases. At this time, under the action of the gravity of the filter block 204, the energy storage mechanism 3 drives the torsion spring 202 to store energy, and the limiting mechanism 4 works synchronously. When the dust weight of the filter block 204 reaches the replacement requirement, the limiting mechanism 4 no longer limits the switching turntable 201, and drives the switching turntable 201 to rotate rapidly through the torsion spring 202, thereby quickly rotating the filter block 204 at the first station a to the second station b, and the adjacent position is quickly supplemented to the first station a, thereby achieving the purpose of automatically and quickly replacing the filter block 204 without affecting the adjacent filter block 204, ensuring the stability of the switching, allowing the calcination work to continue, and increasing the calcination efficiency.

[0041] like Figure 3 , Figure 8 and Fig.11 As shown, as a preferred embodiment of the present invention, the energy storage mechanism 3 includes an energy storage turntable 301 rotatably connected to the mounting platform 103, the energy storage turntable 301 is meshed with a rotating gear 302, the energy storage turntable 301 contacts the inner wall of the switching turntable 201, the rotating gear 302 is rotatably connected to the inner wall of the switching turntable 201, a bevel gear set 303 is coaxially fixedly installed on the surface of the rotating gear 302, a secondary bevel gear 304 is fixedly installed on one end of the bevel gear set 303 away from the rotating gear 302, the secondary bevel gear 304 is meshed with a linkage bevel gear 305, the linkage bevel gear 305 is coaxially fixedly connected with a rotating gear cylinder 306, the rotating gear cylinder 306 is meshed with a moving rack 307, a connecting block 309 is fixedly installed on the surface of the moving rack 307, a tension spring 308 is fixedly installed on the surface of the connecting block 309, a support block 310 is fixedly installed on the surface of the connecting block 309, and the surface of the support block 310 contacts the filter block 204.

[0042] In actual application of the embodiment of the present invention, as the dust passing through the filter block 204 increases, Figure 3 As shown, from Figure 3From the front view direction, at this time, the support block 310 is squeezed downward by the gravity of the filter block 204, and the support block 310 drives the moving rack 307 to move downward through the connecting block 309, and the downward movement of the moving rack 307 drives the rotating gear cylinder 306 to rotate. It should be noted here that the moving rack 307 and the rotating gear cylinder 306 are not in a meshing state at the beginning, ensuring that the subsequent rotation generated at the first station a will not affect the moving rack 307 at other stations, resulting in motion interference problems. The purpose of setting the rotating gear cylinder 306 to a cylindrical shape is to always mesh with the rotating gear cylinder 306 when the moving rack 307 moves horizontally, such as Fig.11 As shown, at this time, the rotation of the rotating gear cylinder 306 drives the linkage bevel gear 305 to rotate synchronously, and the linkage bevel gear 305 drives the secondary bevel gear 304 to rotate through the meshing action with the secondary bevel gear 304, and then drives the rotating gear 302 to rotate through the bevel gear set 303. It should be noted here that the same group of bevel gear sets 303 are set in different directions, that is, one of the bevel gears in the bevel gear set 303 is symmetrically set, thereby ensuring that the rotating gears 302 in the same group rotate in the same direction, and the rotation of the rotating gear 302 drives the energy storage turntable 301 to rotate, as shown in FIG. Figure 8 As shown, at this time, the rotation of the energy storage rotating disk 301 drives the torsion spring 202 to rotate and store energy, thereby storing energy through the increase of the gravity of the filter block 204 during the filtering process to meet the power for subsequent rotation switching.

[0043] like Figure 3 , Figure 6 and Fig. 9 As shown, as another preferred embodiment of the present invention, the limiting mechanism 4 includes a sliding groove rod 401 slidably connected to the inner wall of the switching turntable 201, the sliding groove rod 401 is slidably connected to the movable rack 307, and the end of the sliding groove rod 401 away from the switching turntable 201 is in contact with the limiting turntable 402, and six limiting pins 403 are arranged on the surface of the limiting turntable 402, each limiting pin 403 is slidably connected to the switching turntable 201, and the side of the limiting turntable 402 away from the limiting pin 403 is fixedly connected to the mounting table 103 through a supporting spring 404, and the limiting turntable 402 is coaxially rotatably connected to the energy storage turntable 301.

[0044] In actual application of the embodiment of the present invention, as the gravity of the filter block 204 increases during the dust removal process, Figure 3 As shown, at this time, the filter block 204 drives the slide rod 401 to move downward by moving the rack 307, as shown in FIG. Fig. 9 As shown, from Fig. 9 From the front view direction, the downward movement of the slide rod 401 drives the limit turntable 402 to move downward, and the downward movement of the limit turntable 402 drives the limit pin 403 to move downward. Figure 6As shown, the support spring 404 is compressed. At this time, as the gravity increases, when the limit pin 403 reaches the limit limit of the switching dial 201, the increase in gravity makes the limit pin 403 no longer block the switching dial 201, and the switching dial 201 rotates under the elastic potential energy of the torsion spring 202, so that the first station a moves to the second station b, thereby achieving the purpose of automatic switching without affecting the filter block 204 at the adjacent end, ensuring the smoothness of the switching during movement.

[0045] like Figure 3 , Figure 4 and Figure 5 As shown, as another preferred embodiment of the present invention, the device also includes a release mechanism 6, which includes six sliding rods 601 installed on the switching turntable 201, and each sliding rod 601 has a moving block 602 fixedly installed at one end away from the unloading mechanism 5, and the moving block 602 is slidably connected to the surface of the switching turntable 201, and the surface of the moving block 602 is rotatably connected to two swing rods 604, and each swing rod 604 has an end away from the moving block 602 that is rotatably connected to a right-angle slider 605, and the right-angle slider 605 is slidably connected to the surface of the switching turntable 201, and the inner wall of the right-angle slider 605 is slidably connected to the connecting block 309, and the end of the tension spring 308 away from the connecting block 309 is fixedly connected to the right-angle slider 605.

[0046] In actual application of the embodiment of the present invention, when the switch dial 201 rotates, Figure 4 As shown, at this time, the sliding rod 601 is driven to move along the trajectory of the unloading mechanism 5. At this time, under the action of the unloading mechanism 5, the sliding rod 601 is driven to move away from the central axis of the switching turntable 201, as shown in FIG. Figure 5 As shown, from Figure 5 From the front view, the movement of the sliding rod 601 drives the moving block 602 to move away from the central axis of the switching turntable 201, thereby driving the swing rod 604 to swing. The swing of the swing rod 604 drives a set of right-angle sliders 605 to move in the opposite direction, such as Figure 3 As shown, from Figure 3 When reaching the second station b, the right-angle slider 605 drives the support block 310 to move to both sides through the connecting block 309, and no longer supports the filter block 204. At this time, the filter block 204 falls from the top, thereby achieving the function of automatically unloading the filter block 204.

[0047] like Figure 4As shown, as another preferred embodiment of the present invention, the unloading mechanism 5 includes a fixed disk 501 fixedly mounted on the mounting table 103, the inner wall of the fixed disk 501 is provided with an equal-diameter groove 502, the inner wall of the fixed disk 501 is also provided with a telecentric groove 503, the equal-diameter groove 502 and the telecentric groove 503 are connected end to end, the surface of the equal-diameter groove 502 is in contact with the sliding rod 601, the surface of the telecentric groove 503 is in contact with the sliding rod 601, and the fixed disk 501 is rotatably connected to the switching turntable 201.

[0048] In actual application of the embodiment of the present invention, when the switch dial 201 rotates, Figure 4 As shown, at this time, the release mechanism 6 moves along the trajectory of the equal-diameter groove 502 to the telecentric groove 503. Due to the trajectory of the telecentric groove 503, the sliding rod 601 is driven to move away from the central axis of the switching turntable 201, so that the support block 310 no longer supports the filter block 204, thereby achieving the purpose of automatically unloading the filter block 204. When it rotates again from the second station b to the adjacent station, the sliding rod 601 moves from the telecentric groove 503 to the equal-diameter groove 502, driving the support block 310 to reset. At this time, an automatic loading device can be set on this adjacent station to automatically load the filter block 204, thereby achieving the purpose of automatic cycle switching.

[0049] like Figure 4 As shown, as another preferred embodiment of the present invention, the device further comprises a collecting mechanism 7, the collecting mechanism 7 comprises a collecting box 701 fixedly mounted on the surface of the furnace drum 101, and a recovery door 702 is rotatably connected to the surface of the collecting box 701.

[0050] In practical application, the embodiment of the present invention is as follows: Figure 4 As shown, the filter block 204 unloaded at the second station b will directly fall into the collection box 701. When recycling is required, the employee only needs to open the recycling door 702 to recycle the used filter block 204, thereby realizing the function of rapid recycling by the employee.

[0051] like Figure 5 As shown, as another preferred embodiment of the present invention, the surface of the moving block 602 is connected to the inner wall of the switching turntable 201 through a return spring 603.

[0052] In practical application, the embodiment of the present invention is as follows: Figure 5 As shown, the sliding rod 601 is always in contact with the surfaces of the equal-diameter groove 502 and the telecentric groove 503 by the action of the return spring 603, thereby increasing the stability of the movement.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
