Description

Technical Field

[0001] The utility model relates to the technical field of rubber compound production equipment, in particular to a dust removal device for rubber compound production. Background Art

[0002] Currently, the mixing process for rubber compounding generally uses an open operation. After the raw rubber is put into the kneader, white carbon black is added to the kneader in batches for mixing. There is no dust removal device. Therefore, the white carbon black overflowing from the kneader during the mixing process will float into the air, causing inconvenience to the operators' work. At the same time, the scattered white carbon black will harm the health of the workers. However, due to the relatively simple structure of the traditional dust removal device used in rubber compound production, the dust removal device is unable to filter the dust sucked into the pipe during operation. At the same time, after long-term use, a lot of dust will accumulate inside the device, which is difficult to clean, affecting the user's normal use of the dust removal device.

[0003] Patent document No. 2015206555780 discloses a dust removal device for rubber compound production, comprising a kneading machine, a dust hood disposed directly above the kneading machine, the dust hood connected to an oil removal device via an air duct, the oil removal device connected to a dust removal tank via a pipeline, three layers of filter screens disposed from bottom to top within the dust removal tank, an air pump connected to the dust removal tank disposed above the filter screen, a dust collection tank connected to the dust removal tank disposed below the dust removal tank, a vibrator disposed on the periphery of the dust removal tank, and an air blowing mechanism disposed on the top surface of the dust removal tank. The utility model removes oil before dust removal, preventing the long-term accumulation of emulsified oil from clogging the filter screen, making it easier to clean the dust removal device. At the same time, dust particles are separated from gas under the three layers of filter screen, preventing the emission of dust from polluting the environment.

[0004] The above document discloses a dust removal device for rubber compound production that adds an oil removal function to the device, avoids filter clogging, and makes cleaning of the dust removal device easier. However, after long-term dust removal, some dust will adhere to the inner wall of the device, which is very difficult to clean.

[0005] It can be seen from this that the existing dust removal device for rubber compound production does not have the function of cleaning the dust attached to the inner wall of the device. It is necessary to improve the existing deficiencies and provide a function that can easily clean the dust on the inner wall. Utility Model Content

[0025] See also Figure 1 - Figure 4As shown, the utility model is a dust removal device for rubber compound production, comprising a dust box 1, air delivery pipe assemblies 2 are provided on both sides of the dust box 1, a dust cleaning assembly 3 and a filter element 4 are provided inside the dust box 1, the dust box 1 comprises a dust box body 101, a partition plate 105 is provided inside the dust box body 101, the partition plate 105 divides the dust box body 101 into two cavities, an upper and a lower cavity, the dust cleaning assembly 3 comprises a motor 301, the motor 301 is mounted on the top of the dust box body 101 through a bracket 302, and the output end of the motor 301 is connected to a rotary The shaft 303 passes through the top of the dust box body 101 and the partition plate 105 and extends to the interior of the dust box body 101. The upper part of the shaft 303 is fixedly connected to two cross beams 304, and one end of the cross beam 304 is fixedly connected to the first dust cleaning rod 305. The first dust cleaning rod 305 is attached to the inner wall of the dust box body 101. The bottom of the shaft 303 is fixedly connected to two inclined beams 306, and one end of the inclined beam 306 is fixedly connected to the second dust cleaning rod 307. The second dust cleaning rod 307 is attached to the conical inner wall of the lower part of the dust box body 101. The purpose of this arrangement is that after the dust removal device has been used for a long time, a lot of dust accumulates inside, and some dust adheres to the inner wall of the dust box body 101. At this time, the motor 301 can be turned on to make the motor 301 drive the rotating shaft 303 to rotate, and at the same time drive the first dust cleaning rod 305 and the second dust cleaning rod 307 to be installed. Since the first dust cleaning rod 305 and the second dust cleaning rod 307 are in contact with the inner wall of the dust box body 101, the dust attached to the inner wall of the dust box body 101 can be swept off and collected in the lower conical cavity of the dust box body 101.

[0026] The top of the dust box body 101 is provided with several mounting cylinders 104, and the bottom of the dust box body 101 is provided with a dust discharge port 102. The outside of the dust discharge port 102 is provided with an external thread. The dust box 1 includes a sealing cover 103, which is threadedly connected to the dust discharge port 102. The purpose of this arrangement is to prevent internal dust from overflowing.

[0027] The surface of the partition plate 105 is provided with a plurality of holes, and each hole is equipped with a sealing ring 106. The purpose of such arrangement is to be used for the installation of the filter element 4, and the sealing ring can effectively prevent the gas from flowing out from the gap.

[0028] The air supply pipe assembly 2 includes a dust hood 201, which is connected to the dust box body 101 through an air inlet pipe 202. The air supply pipe assembly 2 includes a fan 204, which is connected to the dust box body 101 through a first exhaust pipe 203, and the fan 204 is connected to the exhaust port 206 through a second exhaust pipe 205.

[0029] The filter element 4 includes a filter element body 401. A first filter screen 403 is disposed within the bottom interior of the filter element body 401. A second filter screen 404 is disposed above the first filter screen 403. An activated carbon plate 405 is disposed above the second filter screen 404. The purpose of this arrangement is that the first filter screen 403, the second filter screen 404, and the activated carbon plate 405 are disposed within the filter element. The double-layer filter screens intercept a significant portion of the dust, and the activated carbon plate 405 then filters and absorbs toxic substances in the air, thereby producing clean air. The clean air then flows out of the exhaust hole 406 and along the first and second exhaust pipes 203 and 205, ultimately being discharged from the exhaust port 206 back into the environment.

[0030] A plurality of vent holes 406 are evenly arranged around the upper portion of the filter element body 401, and a cap 402 is mounted on the top of the filter element body 401. The outer diameter of the cap 402 is larger than the outer diameter of the mounting cylinder 104. This arrangement is intended to facilitate the installation of the filter element 4.

[0031] During use, after the device is started, the fan 204 starts to rotate to generate negative pressure, thereby sucking the dust into the dust hood 201, and the dust enters the dust box 1 through the air inlet pipe 202. Large particles of dust will gradually settle into the conical cavity at the bottom of the dust box body 101 under the action of gravity, while small particles of dust float upward under the action of the airflow and enter the filter element 4 with the airflow. The filter element is provided with a first filter screen 403, a second filter screen 404 and an activated carbon plate 405. Most of the dust is intercepted by the double-layer filter screen, and then the toxic substances in the air are absorbed under the filtration of the activated carbon plate 405, thereby obtaining clean air. The clean air then flows out from the exhaust hole 406 and flows along the first exhaust pipe 203 and the second exhaust pipe 205, and is finally discharged from the exhaust port 206 back to the environment.

[0032] After the dust removal device has been used for a long time, a lot of dust accumulates inside, and some dust adheres to the inner wall of the dust box body 101. At this time, the motor 301 can be turned on to make the motor 301 drive the rotating shaft 303 to rotate, and at the same time drive the first dust cleaning rod 305 and the second dust cleaning rod 307 to be installed. Since the first dust cleaning rod 305 and the second dust cleaning rod 307 are in contact with the inner wall of the dust box body 101, the dust attached to the inner wall of the dust box body 101 can be swept off and collected in the lower conical cavity of the dust box body 101.

[0033] When the dust in the device accumulates to a certain amount, the sealing cover 103 at the bottom of the dust box body 101 can be opened to discharge the dust from the dust discharge port 102.

[0034] When the filter element 4 needs to be replaced, the entire filter element 4 only needs to be pulled out from the installation cylinder 104 and a new filter element is installed, thereby realizing rapid replacement of the filter element.
