Description

Technical Field

[0001] The utility model relates to the technical field of acetylene carbon production, in particular to a dust prevention device used in the acetylene carbon black production process. Background Art

[0002] In the process of acetylene carbon black production, the produced acetylene carbon black needs to be packaged. A certain amount of acetylene carbon black is introduced into the packaging bag, and then the packaging bag is sealed. During the packaging process, the workers need to work with the packaging bag containing acetylene carbon black for a long time. The tiny acetylene carbon black near the packaging needs to be absorbed by a dust suction device to prevent the acetylene carbon black from polluting the environment and ensure the health of the workers.

[0003] After searching, the patent number "CN215904764U" mentioned in the text that "the utility model provides a dust collection device for acetylene carbon black production. The utility model relates to the technical field of acetylene carbon black processing equipment, including a packaging machine, one side of the packaging machine is provided with a discharge port, the surface of the discharge port is covered with a first mounting block, both sides of the first mounting block are provided with dust collection ports, one end of the dust collection port is provided with a connecting block, the packaging machine is provided with a dust collection machine on the side opposite to the discharge port, and the output end of the dust collection machine is provided with a bellows". When in use, the utility model sets the first mounting block and the dust collection port. The dust suction port is installed on the outside of the discharge port through the first installation block. When the packaging bag leaves the discharge port, the dust suction port is used to collect the acetylene carbon black floating out of the discharge port immediately through the vacuum cleaner. This can effectively reduce the acetylene carbon black near the discharge port, ensure that the environment will not be polluted, and increase the personal safety of the staff. However, in the production process of acetylene carbon black, a large amount of carbon ash will be generated due to the production of carbon black, and the weight of this carbon ash is relatively light. During the work of the staff, if this carbon ash is not handled in time, it will cause great harm to the health of the staff and cause serious environmental pollution.

[0004] Therefore, we provide a dust prevention device for the acetylene carbon black production process to solve the above problems. Utility Model Content

[0024] Embodiment 1

[0025] See also Figure 1-4 As shown, the utility model provides a technical solution: a dustproof device for acetylene carbon black production process, comprising a dustproof box 1 and a carbon ash filtering mechanism 2, wherein the carbon ash filtering mechanism 2 is installed inside the dustproof box 1;

[0026] The charcoal ash filtering mechanism 2 includes a primary filtering component 21, a fine filtering component 22 and a dustproof pipe 23. The primary filtering component 21 is arranged on the inner side of the dustproof box 1, the fine filtering component 22 is arranged on the left side of the primary filtering component 21, and the dustproof pipe 23 is arranged on the right end of the dustproof box 1.

[0027] Furthermore, the primary filter assembly 21 includes a mounting frame 211, a support plate 212, a flushing inclined plate 213, a large particle filter screen 214 and a large particle collection bin 215. The mounting frame 211 is welded to the inner side of the dust box 1, and the inner side slot of the mounting frame 211 is connected to the support plate 212. A flushing inclined plate 213 is arranged on the lower side of the support plate 212, and a large particle filter screen 214 is installed on the lower side of the flushing inclined plate 213. A large particle collection bin 215 is arranged on the right side of the large particle filter screen 214. When it is needed, the support plate 212 is inserted into the mounting frame 211, and after entering the dust box 1 through the dust pipe 23, it will collide with the flushing inclined plate 213 at the first time, and after blocking large particles or heavy carbon ash, it will fall into the large particle collection bin 215. In this way, during use, large particles of carbon ash can be effectively separated from small particles of carbon ash, and the problem of rapid passage of carbon ash, resulting in poor filtering effect, can be avoided.

[0028] Furthermore, the large particle filter 214 is welded to the scouring ramp 213 and is made of porous stainless steel. The large particle filter 214 can isolate the carbon ash that has not been scoured by the scouring ramp 213 and has fallen due to its own weight, thereby playing a role in checking for leaks and filling gaps.

[0029] Furthermore, the fine filtering component 22 includes an electrostatic generator 221, an electrostatic adsorption net 222, a ceramic impact plate 223, an auxiliary collection bin 224, a multi-bend charcoal ash collection pipe 225 and a suction fan 226. The electrostatic generator 221 is arranged on the left side of the mounting frame 211, the electrostatic adsorption net 222 is welded to the lower side of the electrostatic generator 221, the ceramic impact plate 223 is arranged on the lower right end of the electrostatic adsorption net 222, the auxiliary collection bin 224 is arranged on the lower side of the ceramic impact plate 223, and the lower side of the auxiliary collection bin 224 is welded to the lower side of the auxiliary collection bin 224. A multi-bend charcoal ash collection pipe 225 is connected, and a suction fan 226 is arranged on the left side of the electrostatic adsorption net 222. When it is needed, the suction fan 226 will draw air inward, so that the charcoal ash passes through the dustproof pipe 23, through the primary filter component 21, and is washed onto the ceramic impact plate 223, and then static electricity is generated by the electrostatic generator 221 to electrostatically adsorb the electrostatic adsorption net 222, and smaller particles of charcoal ash will be adsorbed by the electrostatic adsorption net 222, thereby avoiding the discharge of tiny charcoal ash, which may cause damage to the staff.

[0030] Furthermore, the ceramic impact plate 223 is made of ceramic material and has an angle of 75°. When it needs to be used, the ceramic impact plate 223 is attacked by the first wave of wind, and the ceramic material has good corrosion resistance, so the service life can be extended. In addition, the surface of the ceramic impact plate 223 is relatively smooth, and the carbon ash will not hang on the surface of the ceramic impact plate 223. The carbon ash can directly slide into the auxiliary collection bin 224.

[0031] Furthermore, the multi-bend charcoal ash collecting pipe 225 is welded to the auxiliary collecting bin 224, and the multi-bend charcoal ash collecting pipe 225 is welded to the large particle collecting bin 215. When needed, the multi-bend charcoal ash collecting pipe 225 can reduce the problem of charcoal ash reversal.

[0032] Embodiment 2

[0033] See also Figure 1-4 As shown, in contrast to Example 1, as another embodiment of the utility model, an air filter assembly 3 is installed on the left side of the dustproof box 1, and the air filter assembly 3 includes a filter bin 31, a particle water mist generator 32, a drain pipe 33, a filter element dust collector 34 and a water mist collecting bin 35. A filter bin 31 is welded on the left side of the dustproof box 1, a particle water mist generator 32 is arranged on the upper side of the filter bin 31, a drain pipe 33 is welded on the lower side of the filter bin 31, a filter element dust collector 34 is arranged on the left side of the drain pipe 33, and a water mist collecting bin 35 is welded on the lower side of the drain pipe 33. When it is needed, the suction fan 226 draws the filtered air into the filter bin 31, at this time, the particle water mist generator 32 will spray out mist-like water mist, and the carbon ash that has not been adsorbed cleanly in the air will be adsorbed by the water mist, and thus fall into the water mist collecting bin 35 through the drain pipe 33 due to gravity.

[0034] Furthermore, the filter element dust collector 34 and the drain pipe 33 are welded, and the filter element dust collector 34 is a polyester fiber filter element. When it is needed, the filter element dust collector 34 uses a polyester fiber filter element, so the air can be discharged through the filter element dust collector 34 while the air can be finally filtered, and the polyester fiber filter element has a better adsorption effect on carbon ash.

[0035] Working principle: A dust-proof device for the production process of acetylene carbon black is moved to the working position. When in use, the first step is to connect the dust-proof pipe 23 to the acetylene carbon black production air exhaust system. After the connection is completed, the support plate 212 is inserted into the mounting frame 211. The second step is that the suction fan 226 starts to work, and the air line carrying carbon ash flows into the dust-proof box 1 through the dust-proof pipe 23, and the air will contact the flushing inclined plate 213 at the first time. The carbon ash with a larger volume will fall into the large particle collection bin 215 due to the influence of gravity, and the carbon ash with a smaller volume will contact the ceramic impact plate 223 through the large particle filter 214, and then contact the electrostatic adsorption net under the electrostatic generator 221. 222 contacts, in the third step, the filtered air will enter the filter bin 31, and the particulate water mist generator 32 will spray mist into it to adsorb the tiny carbon ash in the air, and fall into the water mist collection bin 35 through the drain pipe 33, and the filter element dust collector 34 will filter the air and then discharge it to the outside. Finally, after running for a period of time, the suction fan 226 is reversed, and the electrostatic generator 221 is disconnected from the electrostatic adsorption net 222. The carbon ash adsorbed on the electrostatic adsorption net 222 will be blown into the auxiliary collection bin 224 and discharged into the large particle collection bin 215 through the multi-bend carbon ash collection pipe 225. In this way, the use process of a dust prevention device for the acetylene black production process is completed.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
