Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust removal equipment for graphite electrode production. Background Technology

[0002] Graphite electrodes are made from petroleum coke and pitch coke as aggregates and coal tar pitch as binder through multiple processes, including raw material calcination, crushing and grinding, batching, kneading, molding, baking, impregnation, graphitization and machining. During these production processes, especially the crushing, grinding and machining stages, a large amount of graphite dust is generated. This dust is characterized by high concentration, easy combustion and toxicity.

[0003] Existing technologies, such as the utility model patent with publication number CN210331987U, disclose a dust removal device for graphite electrode production. This patent uses a carrier plate, with a fan fixedly installed on the upper surface of the carrier plate. A first air collecting hood is fixedly installed on the air inlet side of the fan, and a second air collecting hood is provided on the lower end of the carrier plate. The second air collecting hood and the first air collecting hood are connected by an L-shaped air inlet pipe. Limit buckles are fixedly installed at the contact points between the L-shaped air inlet pipe and the upper and lower surfaces of the carrier plate. A third air collecting hood is fixedly installed on the exhaust side of the fan. A dust collector shell is provided on one side of the fan. The dust collector shell is vertically embedded in the upper surface of the carrier plate. A dust collection hopper is provided at the lower end of the dust collector shell. A cross-shaped mounting piece is fixedly installed at the conical position of the lower end surface of the dust collection hopper. This invention solves the problem of dust collection efficiency being affected by excessive dust inside the dust collector shell, which is a problem in traditional dust removal equipment technology.

[0004] In the use of existing dust removal equipment, such as the aforementioned dust removal equipment, the threaded connections need to be loosened or tightened by rotation. Especially after long-term use, due to dust accumulation, corrosion, or thread wear, the threads may seize up. Disassembly requires a lot of time and effort, which in turn affects the maintenance efficiency of the equipment and causes the problem of low disassembly efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the existing technology that threaded connections need to be loosened or tightened by rotation, especially after long-term use, due to dust accumulation, corrosion or thread wear, which may cause the threads to seize up. Disassembly requires a lot of time and effort, which in turn affects the maintenance efficiency of the equipment and causes low disassembly efficiency. Therefore, a dust removal device for graphite electrode production is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dust removal device for graphite electrode production, comprising a support plate, a fan, and a disassembly assembly. The fan is fixedly mounted on the upper surface of the support plate. A first air collecting hood is fixedly connected to one side of the fan. An L-shaped air inlet pipe is fixedly connected to the end of the first air collecting hood away from the fan.

A third air collecting hood is fixedly connected to the side of the fan away from the first air collecting hood. A dust collector shell is fixedly mounted on the upper surface of the support plate. A dust collection hopper is movably mounted on the lower surface of the dust collector shell. A disassembly assembly is fixedly mounted on the lower surface of the disassembly assembly. A linkage assembly is fixedly mounted on the lower surface of the disassembly assembly. A connecting pipe is fixedly connected to the side of the third air collecting hood away from the fan. The connecting pipe is inserted into the dust collector shell. An exhaust pipe is inserted into the side of the dust collector shell away from the connecting pipe. The disassembly assembly includes a first mounting groove. A first mounting groove is formed on the lower surface of the dust collector shell. A first sealing ring is fixedly connected to the inner wall of the first mounting groove.

[0007] Preferably, a second mounting groove is provided on the upper surface of the dust collection hopper, and a second sealing ring is fixedly connected to the inner wall of the second mounting groove. The surfaces of the second sealing ring and the first sealing ring are in contact. Both the first sealing ring and the second sealing ring are arc-shaped. The cooperation between the first sealing ring and the second sealing ring facilitates the increase of the sealing between the dust collector shell and the dust collection hopper, so as to ensure long-term stable sealing performance.

[0008] Preferably, a mounting block is fixedly connected to the lower surface of the support plate, and a U-shaped groove is formed on the side surface of the mounting block. A slider is slidably connected to the inner wall of the U-shaped groove. The slider is rectangular and has a chamfered side near the dust collection hopper. There are two sliders, which are symmetrically arranged at the center of the dust collection hopper. The sliders facilitate the support of the limiting block to ensure the stability of the limiting block during support.

[0009] Preferably, a baffle is fixedly connected to the side surface of the slider. The baffle is rectangular and contacts the side surface of the mounting block. There are two baffles, which are symmetrically arranged at the center of the slider. The baffles can block the position of the limiting block to prevent the limiting block from sliding down from both sides above the slider.

[0010] Preferably, the mounting block has a through hole on its side surface, and a shaft is slidably connected to the inner wall of the through hole. A guide block is fixedly connected to the side of the shaft away from the mounting block. The guide block is chamfered, and a limit spring is fixedly connected to the side of the guide block away from the dust collection hopper. The side of the limit spring away from the guide block is fixedly connected to the mounting block. The limit spring facilitates the application of a reset force to the guide block, ensuring that the guide block can drive the slider to support the position of the limit block.

[0011] Preferably, a limiting block is fixedly connected to the outer arc surface of the dust collection hopper. The limiting block is chamfered and contacts the upper surface of the slider and the side surface of the baffle. There are two limiting blocks, which are symmetrically arranged at the center of the dust collection hopper. The limiting blocks facilitate the restriction of the position of the dust collection hopper.

[0012] Preferably, the lower surface of the mounting block is provided with a linkage component, the linkage component includes a long plate, the lower surface of the mounting block is fixedly connected to the long plate, the long plate is rectangular, there are two long plates, the two long plates are located at the center of the dust collection hopper and are arranged symmetrically from left to right, the upper surface of the long plate is provided with a guide groove, the guide groove facilitates the direction of movement of the connecting rod, so as to ensure that the connecting rods on both sides can move synchronously.

[0013] Preferably, the long plate is slidably connected to a connecting rod on the inner wall of the guide groove. The side of the connecting rod away from the long plate is fixedly connected to a shaft. A pull rod is fixedly connected to one side of the long plate. The pull rod allows the operator to move the long plates on both sides simultaneously.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] In this utility model, by setting up a disassembly component, when the dust collection hopper needs to be disassembled, the worker holds the pull rod with one hand and pulls the pull rod outward. The pull rod is forced to move the long plate, and the long plate moves and then engages with the guide groove, which in turn moves the connecting rod. Under the action of the long plate, the connecting rod moves along the guide groove, and the movement causes the shaft to move synchronously. Then the shaft moves outward, and the movement causes the guide block to move. The movement of the guide block compresses the limiting spring, and the limiting spring deforms under the pressure, causing the slider to move synchronously. The movement causes the slider to gradually move away from the limiting block.

[0016] Then, until it is completely away from the limit block and loses all constraint on the limit block, the dust collection hopper can be disassembled. The staff can then separate the dust collection hopper from the dust collector shell and clean the inside of the dust collector shell. By setting up the disassembly components, the disassembly process of the dust collection hopper can be changed from tedious screw tightening to simply loosening the clamps or opening the buckles. The installation process is also convenient, which greatly shortens the downtime during equipment maintenance and improves production efficiency. Attached Figure Description

[0024] Please see Figures 1-5This utility model provides a technical solution: a dust removal device for graphite electrode production, including a support plate 1, a fan 2, and a disassembly assembly 9.

A connecting pipe 11 is fixedly connected to the side of the third air collecting hood 6 away from the fan 2. The connecting pipe 11 is inserted into the dust collector shell 7. An exhaust pipe 12 is inserted into the side of the dust collector shell 7 away from the connecting pipe 11.

[0025] The following section will explain the specific settings and functions of its disassembly component 9 and linkage component 10.

[0026] In this embodiment: the disassembly component 9 includes a first mounting groove 91. The lower surface of the dust collector housing 7 is provided with the first mounting groove 91, and the inner wall of the first mounting groove 91 is fixedly connected with a first sealing ring 92.

[0027] Specifically, a second mounting groove 93 is provided on the upper surface of the dust collection hopper 8, and a second sealing ring 94 is fixedly connected to the inner wall of the second mounting groove 93. The surfaces of the second sealing ring 94 and the first sealing ring 92 are in contact, and both the first sealing ring 92 and the second sealing ring 94 are arc-shaped.

[0028] The effect achieved by the above components is that the cooperation between the first sealing ring and the second sealing ring 94 facilitates the increase of the sealing between the dust collector housing 7 and the dust collection hopper 8, so as to ensure long-term stable sealing performance.

[0029] Specifically, a mounting block 95 is fixedly connected to the lower surface of the bearing plate 1. A U-shaped groove 96 is opened on the side surface of the mounting block 95. A slider 97 is slidably connected to the inner wall of the U-shaped groove 96. The slider 97 is rectangular. The side of the slider 97 near the dust collection hopper 8 is chamfered. There are two sliders 97. The two sliders 97 are located at the center of the dust collection hopper 8 and are arranged symmetrically from left to right.

[0030] The effect achieved by the above components is that the slider 97 facilitates the support of the position of the limiting block 913, thereby ensuring the stability of the limiting block 913 when it is supported.

[0031] Specifically, a baffle 98 is fixedly connected to the side surface of the slider 97. The baffle 98 is rectangular and contacts the side surface of the mounting block 95. There are two baffles 98, which are symmetrically arranged at the center of the slider 97.

[0032] The effect achieved by the above components is that the baffle 98 can block the position of the limiting block 913 to prevent the limiting block 913 from sliding down from both sides above the slider 97.

[0033] Specifically, a through hole 99 is provided on the side surface of the mounting block 95. A shaft 911 is slidably connected to the inner wall of the mounting block 95 in the through hole 99. A guide block 910 is fixedly connected to the side of the shaft 911 away from the mounting block 95. The guide block 910 is chamfered. A limit spring 912 is fixedly connected to the side of the guide block 910 away from the dust collection hopper 8. The side of the limit spring 912 away from the guide block 910 is fixedly connected to the mounting block 95.

[0034] The effect achieved by the above components is that the limiting spring 912 facilitates the application of a reset force to the guide block 910, so as to ensure that the guide block 910 can drive the slider 97 to support the position of the limiting block 913.

[0035] Specifically, a limiting block 913 is fixedly connected to the outer arc surface of the dust collection hopper 8. The limiting block 913 is chamfered and contacts the upper surface of the slider 97. The limiting block 913 contacts the side surface of the baffle 98. There are two limiting blocks 913, which are symmetrically arranged at the center of the dust collection hopper 8.

[0036] The effect achieved by the above components is that the position of the dust collection hopper 8 can be easily restricted by the limiting block 913.

[0037] Specifically, a linkage component 10 is provided on the lower surface of the mounting block 95. The linkage component 10 includes a long plate 101. The long plate 101 is fixedly connected to the lower surface of the mounting block 95. The long plate 101 is rectangular. There are two long plates 101. The two long plates 101 are located at the center of the dust collection hopper 8 and are arranged symmetrically from left to right. A guide groove 102 is provided on the upper surface of the long plate 101.

[0038] The effect achieved by the above components is that the guide groove 102 facilitates the direction of movement of the connecting rod 103, so as to ensure that the connecting rods 103 on both sides can move synchronously.

[0039] Specifically, a connecting rod 103 is slidably connected to the inner wall of the guide groove 102 on the long plate 101. The side of the connecting rod 103 away from the long plate 101 is fixedly connected to the shaft 911, and a pull rod 104 is fixedly connected to one side of the long plate 101.

[0040] The effect achieved by the above-mentioned components is that, through the pull rod 104, it is convenient for the staff to move the long plates 101 on both sides at the same time.

[0041] Working principle: When the dust collection hopper 8 needs to be disassembled, the operator holds the pull rod 104 with one hand and pulls the pull rod 104 outward. The pull rod 104 is forced to move the long plate 101. The long plate 101 moves and then cooperates with the guide groove 102, which in turn drives the connecting rod 103 to move. Under the action of the long plate 101, the connecting rod 103 moves along the guide groove 102. The movement drives the shaft 911 to move synchronously. Then the shaft 911 moves outward, which drives the guide block 910 to move. The guide block 910 moves and squeezes the limiting spring 912. The limiting spring 912 is squeezed and deformed, which drives the slider 97 to move synchronously. The movement causes the slider 97 to gradually move away from the limiting block 913.

[0042] Then, until it is completely away from the limit block 913 and loses all restraint on the limit block 913, the dust collection hopper 8 is disassembled. The staff can then separate the dust collection hopper 8 from the dust collector housing 7 and clean the inside of the dust collector housing 7. By setting the disassembly component 9, the disassembly process of the dust collection hopper 8 can be changed from tedious screw tightening to simple loosening of the clamp or opening of the buckle. The installation process is also convenient, which greatly shortens the downtime during equipment maintenance and improves production efficiency.
