Description

Technical Field

[0001] This utility model relates to the field of rubber processing technology, specifically to a rubber processing exhaust gas treatment device. Background Technology

[0002] During rubber processing, processes such as mixing and vulcanization generate a large amount of complex exhaust gas. This exhaust gas contains not only sulfides with foul odors such as hydrogen sulfide and carbon disulfide, but also volatile organic compounds such as benzene, toluene, and xylene, as well as particulate matter such as carbon black. If these pollutants are directly released into the atmosphere, they will cause serious harm to the environment and human health.

[0003] There are various methods for treating exhaust gases from rubber processing, among which electrostatic adsorption is a relatively effective one. Traditional electrostatic adsorption equipment uses flat plates or pipes as anode adsorption plates, and then removes dust from the surface of the anode adsorption plates periodically by striking or washing. However, dust removal by striking is not only noisy but also difficult to effectively remove dust, while dust removal by washing is not only time-consuming but also poses a risk of electric leakage. Using flat plates or pipes as anode adsorption plates also requires the installation of a grid in front to even out airflow distribution and change the flow rate. Adding a grid not only increases the size of the equipment but also requires regular cleaning. Utility Model Content

[0009] Preferably, there are four blades, which are evenly welded in a cross shape around the hollow shaft. The width of the blades is greater than the diameter of the hollow shaft. When the blades of two adjacent anode shafts are perpendicular to the air intake direction, the distance between the blades is very small, and the distance between the blades and the inner wall of the air intake box is also very small.

[0010] Preferably, the upper and lower plates of the air intake box are provided with bearing mounting holes and wire thread holes. The lower plate of the air intake box is provided with ash discharge holes around the wire thread holes. The outer diameter of the retaining ring is larger than the inner diameter of the bearing mounting hole and the distance between the two is very small.

[0013] This utility model provides a device for treating exhaust gas from rubber processing, which has the following beneficial effects:

[0014] 1. This rubber processing exhaust gas treatment device, through the cooperation of the anode rotating shaft and the motor, enables the rubber processing exhaust gas treatment device to have good dust removal effect of anode plate and low noise. The centrifugal force generated by the high-speed rotation of the anode rotating shaft driven by the motor removes the dust adsorbed on the surface, which not only has a good effect but also does not generate much noise.

[0015] 2. This rubber processing exhaust gas treatment device, through the cooperation of the anode rotating shaft and the motor, enables the rubber processing exhaust gas treatment device to achieve high dust removal efficiency and safety of the anode plate. The centrifugal force generated by the high-speed rotation of the anode rotating shaft driven by the motor removes the dust adsorbed on the surface. This not only eliminates the need to spend time disassembling the anode for dust removal, thus improving efficiency, but also avoids leakage caused by human operation, thereby reducing the risk of electric shock.

[0016] 3. This rubber processing exhaust gas treatment device, through the coordinated arrangement of the anode shaft, shaft gear, transmission gear and motor, achieves the effect of reducing size and maintenance costs by eliminating the need for a grid. Since the anode shaft is rotatable and has cross-shaped blades around its perimeter, the rotation of all anode shafts and the change of the angle between the blades through the coordination of the shaft gear, transmission gear and motor can make the anode shaft have the effect of a grid, thus eliminating the need for a grid, reducing the size of the equipment and lowering maintenance costs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example

[0026] Please see Figures 1 to 6This utility model provides a technical solution: a rubber processing exhaust gas treatment device, including an air inlet box 1, a rotatable anode shaft 2 installed between the upper and lower plates of the air inlet box 1, the anode shaft 2 including a hollow shaft 201, blades 202 welded around the periphery of the hollow shaft 201, retaining rings 203 welded above and below the blades 202, a shaft gear 3 that rotates synchronously with the hollow shaft 201 installed on the top, a transmission gear 4 arranged between the two shaft gears 3 on the top of the air inlet box 1, and a fixed connection between the upper and lower plates of the air inlet box 1. The inlet box 1 is equipped with a cathode wire 5 located in the middle of four anode shafts 2. An inverted L-shaped plate 6 is fixedly installed on the top of the inverted L-shaped plate 6. A motor 7 is fixedly installed on the top surface of the inverted L-shaped plate 6. A bearing seat 8 is fixedly installed on the top wall of the inverted L-shaped plate 6. A drive gear 9 driven by the motor 7 and meshing with one of the shaft gears 3 is installed below the bearing seat 8. A signal sensing rod 10 that rotates synchronously with the drive gear 9 is set above it. A proximity switch 11 with the same height as the signal sensing rod 10 is threadedly connected to one side of the inverted L-shaped plate 6.

[0027] Specifically, the intake box 1 is made of metal and is grounded. The anode shaft 2 is in contact with the intake box 1 and grounded through a deep groove ball bearing 12. All cathode wires 5 are connected to high-voltage lines with a voltage between 30KV and 70KV. Exhaust gas flows in from one end of the intake box 1 and then flows out from the other end. The flow rate can be changed by changing the angle of the anode shaft 2. When the signal sensing rod 10 is sensed by the proximity switch 11, one of the blades 202 is perpendicular to the intake direction.

[0028] Please see Figure 4 The top of the hollow shaft 201 is sealed and has two threaded holes. The shaft gear 3 is sleeved on the top of the hollow shaft 201 and fixedly connected by two screws.

[0029] Specifically, a slot is provided in the middle position below the shaft gear 3 to fit with the hollow shaft 201 with a small clearance. The shaft gear 3 is sleeved with the hollow shaft 201 through the slot and then locked with two screws. The two screws have a diameter of 6mm and also serve to transmit torque.

[0030] Please see Figures 4 to 6 There are four blades 202, which are evenly welded in a cross shape around the hollow shaft 201. The width of the blades 202 is greater than the diameter of the hollow shaft 201. When the blades 202 of two adjacent anode shafts 2 are perpendicular to the air intake direction, the distance between the blades 202 is very small, and the distance between the blades 202 and the inner wall of the air intake box 1 is also very small.

[0031] Specifically, because all the anode shafts 2 rotate synchronously, when the blades 202 around the anode shaft 2 are perpendicular to the air intake direction, the distance between the blades 202 is very small, that is, the airflow channel is very small, and the amount of gas flowing is very small. When the blades 202 around the anode shaft 2 are at 45° to the air intake direction, the distance between the blades 202 is the largest, and the amount of gas flowing is very large. Since the blades 202 of the anode shaft 2 are wide and interlaced, the blades 202 can block the airflow, which can make the airflow swirl and make the airflow more uniform.

[0032] Please see Figures 3 to 5 The upper and lower plates of the air intake box 1 are provided with bearing mounting holes 101 and wire thread holes 102. The lower plate of the air intake box 1 is provided with ash discharge holes 103 around the wire thread holes 102. The outer diameter of the retaining ring 203 is larger than the inner diameter of the bearing mounting hole 101 and the distance between the two is very small. A deep groove ball bearing 12 for connecting the hollow shaft 201 is installed on the outside of the bearing mounting hole 101. An insulating sleeve 13 for fixing the cathode wire 5 is connected to the inside of the wire thread hole 102 by threads.

[0033] Specifically, the bearing mounting hole 101 is a stepped hole with the larger end facing outward, so that the deep groove ball bearings 12 are all disassembled and installed from the outside for easy maintenance. When the dust in the exhaust gas is adsorbed into a clump by the anode shaft 2 and falls off, it is discharged through the ash outlet hole 103. Below the ash outlet hole 103 is a dust collection box. The function of the retaining ring 203 is to cover the inside of the bearing mounting hole 101 to prevent dust from entering the deep groove ball bearings 12. At the same time, all deep groove ball bearings 12 need to be equipped with a sealing cover. The insulating sleeve 13 is made of plastic.

[0034] Please see Figures 2 to 3 The transmission gear 4 is mounted on the stepped shaft above the air intake box 1 via bearings. The transmission gear 4 can rotate and mesh with the adjacent shaft gear 3. The transmission gear 4 is distributed between all the vertical shaft gears 3 and between a row of horizontal shaft gears 3.

[0035] Specifically, all shaft gears 3 rotate synchronously through the transmission gear 4, and all blades 202 of the anode shaft 2 need to be set in one direction so that all blades 202 rotate synchronously in the same direction, so that when the motor 7 drives the anode shaft 2 to rotate, the blades 202 can change the gas flow rate.

[0036] In use, firstly, the motor 7 is started to drive the anode shaft 2 to rotate, and the angle of the blades 202 is corrected by the signal sensing rod 10 and the proximity switch 11. The origin of the deflection angle of the blades 202 in one direction is set to be perpendicular to the air intake direction. That is, the result of the motor 7 correcting the blades 202 to the origin is the minimum air intake. Then, the blades 202 are deflected at a certain angle according to the exhaust gas flow rate. The deflection angle is set between 0 and 45°. When the blades 202 are deflected to 45°, the distance between the blades 202 of two adjacent anode shafts 2 is the largest, and the air intake channel is the widest. Therefore, the air flow rate can be changed by changing the angle of the anode shaft 2. Since the blades 202 of the anode shaft 2 are interlaced in the air intake box 1, the airflow pattern can be adjusted. To prevent interference, the airflow speed can be slowed down and evenly distributed. The anode shaft 2 can rotate and the angle of the blades 202 can be changed, making it function as a grille. When the airflow flows through the intake box 1 and passes between the blades 202, the dust particles in the exhaust gas will be attached to the free electrons and ions generated by the ionization of the air by the cathode wire 5 in the middle of the blades 202 and become charged. The negatively charged dust particles will move towards the blades 202 under the action of the electric field force and eventually be adsorbed on the blades 202. At this time, it is only necessary to periodically drive the anode shaft 2 to rotate at high speed through the motor 7 to throw the dust attached to the blades 202 out by centrifugal force. Compared with the traditional method of cleaning by knocking, cleaning by centrifugal force is not only quieter but also more effective.

[0037] In summary, this rubber processing exhaust gas treatment device removes adsorbed dust from the surface by using centrifugal force generated by the high-speed rotation of the anode shaft 2 driven by the motor 7. This method is not only effective but also produces minimal noise. Removing adsorbed dust from the surface by using centrifugal force generated by the high-speed rotation of the anode shaft 2 driven by the motor 7 eliminates the need for time-consuming anode dust removal, thus improving efficiency and avoiding leakage caused by human operation, thereby reducing the risk of electric shock. Since the anode shaft 2 is rotatable and has cross-shaped blades 202 around its perimeter, the shaft gear 3, transmission gear 4, and motor 7 work together to rotate all the anode shafts 2 and change the angle between the blades 202, enabling the anode shaft 2 to function as a grid. This eliminates the need for additional grids, reducing the equipment size and maintenance costs.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
