Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pumps, in particular to a pre-pump exhaust gas treatment device. Background Art

[0002] In the field of battery manufacturing equipment, the widespread application of vacuum processes has made dry screw pumps and diaphragm pumps common choices. However, these pumps often face problems such as jamming, wear of internal structural parts, and blockage of the exhaust pipe. To address the above problems, the existing technology usually installs a filter device in front of the pump. Although the stainless steel filter element can filter larger foreign matter and some exhaust gas particles, the temperature of the stainless steel filter element itself is not much different from the exhaust gas temperature during long-term use, and it cannot effectively remove the aerosolized exhaust gas particles. The aerosolized exhaust gas particles can still enter the pump body and the exhaust pipe, causing the exhaust pipe behind the pump to be easily blocked. Especially in coating and boron expansion equipment, the wear and blockage of the pump body are particularly prominent, which directly affects the sedimentation efficiency of solid particles in the exhaust gas.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] In order to avoid clogging of the pump body, the existing technology usually installs a filter device for filtering exhaust gas in front of the pump. Although the stainless steel filter element can filter larger foreign matter and some exhaust gas particles, the stainless steel filter element cannot effectively remove aerosol exhaust gas particles. Aerosol exhaust gas particles can still enter the pump body and the waste discharge pipeline, causing the pump body to be blocked, affecting the sedimentation efficiency of solid particles in the exhaust gas.

[0024] To solve the defects of the above-mentioned filter device during use, please refer to Figure 1-Figure 5 The utility model provides a pre-pump exhaust gas treatment device that can fully deposit exhaust gas particles and reduce the amount of waste entering the pump, thereby reducing the risk of blockage. The exhaust gas treatment device is provided with a cylinder body 1, a water tank 2 is fixedly installed on the inner bottom wall of the cylinder body 1, a water cooling pipe 3 is provided on the top of the water tank 2, a water inlet 11 is provided at the bottom of the water tank 2, the lower end of the water inlet 11 extends to the outside of the cylinder body 1, which is convenient for connecting to the external water inlet pipe, the upper end of the water cooling pipe 3 extends to the outside of the cylinder body 1 and is provided with a water outlet 12, a water pump is provided in the water tank to supply water to the water cooling pipe 2, and the water flow direction is from bottom to top, which can more effectively enter the exhaust gas heat in the cylinder body 1, the outer rotating sleeve of the water cooling pipe 3 is provided with a sleeve 4, and the outer rotating sleeve of the sleeve 4 is provided with a plurality of baffles 5 The outer edge of the baffle 5 is fixedly connected to the inner wall of the cylinder body 1. The baffle 5 can be fixed to the inner wall of the cylinder body 1 by welding, and a notch 6 is opened on the baffle 5. The notch 6 is for the exhaust gas to flow, so as to realize the baffle 5's guiding effect on the airflow direction. At the same time, the baffle 5 can also be used as a heat absorber to cool the exhaust gas in conjunction with the water-cooling pipe 3. The above components are all made of quartz material to effectively resist acidic gas corrosion and improve temperature resistance. The openings of the notches 6 on two adjacent baffles 5 are in opposite directions. Multiple baffles 5 are equidistantly distributed in the longitudinal direction, and the number of baffles 5 is at least three. Figure 2As shown, an S-shaped airflow channel is formed between the baffle 5, the water-cooling tube 3 and the inner wall of the cylinder body 1. The S-shaped airflow channel can increase the residence time of the exhaust gas in the cylinder body 1. When the exhaust gas passes through the S-shaped airflow channel, the exhaust gas particles can be fully deposited under the action of the water-cooling tube 3, thereby reducing the waste entering the pump, thereby improving the operating environment of the pump body and achieving the purpose of extending the service life.

[0025] As the exhaust gas circulates, some of the sediment in the exhaust gas will fall on the baffle 5. In order to facilitate the cleaning of the sediment on the baffle 5, a plurality of cleaning members 7 are further provided on the sleeve 4. The plurality of cleaning members 7 are respectively arranged above the plurality of baffles 5, and a driving member 8 is provided on the cylinder body 1 to drive the sleeve 4 to rotate, wherein a servo motor 81 is fixedly mounted on one side of the top of the cylinder body 1, and the output end of the servo motor 81 extends to the cylinder body 1 and is fixedly connected to a gear 1 82. The upper end of the sleeve 4 is fixedly sleeved with a gear 2 83 meshing with the gear 1 82. The driving servo motor 81 can drive the gear 2 83 to rotate through the gear 1 82, and the rotation of the gear 2 83 can drive the sleeve 4 to rotate. The sleeve 4 drives the cleaning member 7 to rotate synchronously, and the cleaning member 7 rotates along the baffle 5 to clean the sediment on the baffle 5, so that the sediment falls from the notch 6, and the sediment can fall to the bottom of the cylinder body 1 layer by layer.

[0026] The cleaning member 7 is fixedly mounted on the outside of the frame 4 to clean the cleaning piece 7. The outer edge of the ring 71 is fixedly connected to an extension rod 72. The length of the extension rod 72 is adapted to the radius of the baffle 5. A plurality of connecting springs 73 are fixedly installed inside the extension rod 72. The lower ends of the plurality of connecting springs 73 are jointly installed with a scraper 74. The scraper 74 is slidably mounted inside the extension rod 72. The bottom of the scraper 74 abuts against the baffle 5. The scraper 74 can abut against the baffle 5 through the elastic force of the connecting spring 73. When the frame 4 drives the ring 71 to rotate, the scraper 74 can rotate closely on the baffle 5 to fully scrape off the deposits on the baffle 5.

[0027] Reference Figure 2 As shown, an air outlet 9 is provided on the other side of the top of the cylinder body 1, and an air inlet 10 is provided on one side of the cylinder body 1. The height of the air inlet 10 is 20cm-30cm higher than the bottom of the cylinder body 1, providing a space for accommodating sediments in the exhaust gas.

[0028] When the sediment accumulates to a certain amount, it is necessary to clean the sediment. Therefore, a visual door 13 is symmetrically installed on the outside of the cylinder body 1. The visual door 13 allows for convenient observation of the exhaust gas settling inside the cylinder body 1. When the sediment reaches the level that requires cleaning, the visual door 13 is opened to facilitate cleaning of the sediment. In addition, multiple brake wheels are installed at the bottom of the cylinder body 1. The brake wheels can support the cylinder body 1 and also facilitate the movement of the cylinder body 1.

[0029] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.
