[0002] Mechanical processing refers to the process of changing the shape, size or performance of a workpiece through a mechanical equipment. It can be divided into cutting processing and pressure processing according to the difference in processing methods. With the continuous development of society, there are more and more mechanical processing methods. Some mechanical equipment will generate a lot of exhaust gas when in use, so there are more and more exhaust gas waste heat recovery devices.

[0003] Since there are a lot of impurities in the exhaust gas during automobile processing, the device will use a filter plate to filter out the impurities in the exhaust gas so that the exhaust gas can be better reused. However, in the process of the filter plate filtering harmful impurities and other substances in the exhaust gas, pollutants are easy to adhere to the filter plate and easily cause pollutants to accumulate on the surface of the filter plate, causing the mesh of the filter plate to become clogged and causing the exhaust gas to pass through the filter plate. The speed is affected, thereby reducing the utilization rate of waste heat from the exhaust gas to a certain extent. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-4 , an exhaust gas waste heat treatment device for automobile processing, comprising a heating pipe 1, an air intake pipe 101 is fixedly connected to the right side wall of the heating pipe 1, a spiral pipe 102 is fixedly connected to the end of the air intake pipe 101 located inside the air intake pipe 101, and further comprising:

[0023] A servo motor 2 is fixedly connected to the inner wall of the air inlet pipe 101, a rotating shaft 201 is fixedly connected to the end of the servo motor 2, a circular plate 202 is slidably connected to the inner wall of the air inlet pipe 101, a plurality of first springs 203 are fixedly connected between the circular plate 202 and the inner wall of the air inlet pipe 101, a filter plate 204 is fixedly connected to the end of the circular plate 202, a rotating column 205 is fixedly connected to the side wall of the rotating shaft 201, the rotating column 205 and the filter plate 204 are fitted, and a semicircular ball 206 is fixedly connected to the side wall of the filter plate 204;

[0024] The end of the spiral tube 102 is fixedly connected with a connecting tube 207, the connecting tube 207 passes through the heating tube 1, and the side wall of the connecting tube 207 is fixedly connected with an air outlet pipe 208;

[0025] It should be noted that the exhaust gas passes through the air inlet pipe 101 to the inside of the spiral tube 102 located inside the heating tube 1. Due to the characteristics of the spiral tube 102 itself, the contact area between the spiral tube 102 and the water inside the heating tube 1 is large, which facilitates the use of the exhaust gas to heat the water inside the heating tube 1. Then, the exhaust gas passes through the spiral tube 102 to the outside of the exhaust pipe 208 arranged on the side wall of the connecting tube 207. When the exhaust gas passes through the inside of the air inlet pipe 101, the impurities in the exhaust gas will be filtered out by the filter plate 204, and the impurities will adhere to the surface of the filter plate 204. The servo motor 2 is turned on, and the servo motor 2 drives the rotating shaft 201 to rotate the rotating column 205. The rotating column 205 removes impurities on the surface of the filter plate 204 when rotating, and collides with the semi-circular ball 206 while rotating, so that the filter plate 204 drives the circular plate 202 to slide toward the inner wall of the intake pipe 101, squeezing the first spring 203, causing the first spring 203 to generate a rebound force, and then the filter plate 204 vibrates under the rebound force of the first spring 203, thereby vibrating the impurities in the filter holes inside the filter plate 204 out of the filter holes, so that the filter plate 204 is always in a connected state, avoiding impurities from blocking the filter holes inside the filter plate 204.

[0026] Reference Figure 1-4 The inner wall of the connecting tube 207 is slidably connected with a stopper 3, the top of the stopper 3 is fixedly connected with a connecting column 301, and the connecting column 301 passes through the connecting tube 207;

[0027] A connecting plate 302 is fixedly connected to the top of the connecting column 301, and a second spring 303 is fixedly connected between the connecting plate 302 and the connecting pipe 207, and the second spring 303 is located outside the connecting column 301;

[0028] It should be noted that: under the action of the elastic force of the second spring 303, the connecting column 301 drives the block 3 to be located below the air outlet pipe 208, so that the exhaust gas inside the spiral tube 102 stays inside the spiral tube 102, thereby increasing the time for the exhaust gas to heat the water outside the spiral tube 102, and when the air inlet pipe 101 continues to input exhaust gas into the spiral tube 102, the air pressure inside the spiral tube 102 increases, thereby causing the gas to drive the block 3 to move upward inside the connecting tube 207. At this time, the second spring 303 is squeezed and a rebound force is generated. Until the block 3 moves to the top of the air outlet pipe 208, the gas inside the spiral tube 102 is discharged and the air pressure is reduced. Under the action of the elastic force of the second spring 303, the block 3 returns to its original position, which can increase the time for the exhaust gas to stay inside the spiral tube 102, thereby increasing the time for the exhaust gas to heat the water, so as to enhance the utilization rate of the exhaust gas.

[0029] Reference Figure 1-4The inner wall of the air inlet pipe 101 is fixedly connected with a mounting frame 304, the servo motor 2 is fixed to the inner wall of the air inlet pipe 101 through the mounting frame 304, and the side wall of the air inlet pipe 101 below the filter plate 204 is fixedly connected with a collection box 305;

[0030] A water inlet pipe 306 is fixedly connected to the top of the side wall of the heating tube 1, and a water outlet pipe 307 is fixedly connected to the bottom of the side wall of the heating tube 1;

[0031] It should be noted that the servo motor 2 is fixed to the inner wall of the air inlet pipe 101 through the mounting bracket 304, the collecting box 305 is useful for collecting impurities filtered out by the filter plate 204 and then cleaning them, the water inlet pipe 306 can fill cold water into the heating tube 1, and the water outlet pipe 307 can discharge the hot water after being heated inside the heating tube 1.

[0032] Operation mode: the exhaust gas reaches the inside of the spiral tube 102 located inside the heating tube 1 through the air inlet pipe 101. Due to the characteristics of the spiral tube 102 itself, the contact area between the spiral tube 102 and the water inside the heating tube 1 is large, so it is convenient to use the exhaust gas to heat the water inside the heating tube 1. Then the exhaust gas passes through the spiral tube 102 to the outside of the exhaust pipe 208 arranged on the side wall of the connecting pipe 207. When the exhaust gas passes through the inside of the air inlet pipe 101, the impurities in the exhaust gas will be filtered out by the filter plate 204, and the impurities will adhere to the surface of the filter plate 204. Turn on the servo motor 2, and the servo motor 2 will drive the rotating shaft 201 to rotate the rotating column 205. The rotating column 205 removes impurities on the surface of the filter plate 204 when rotating, and collides with the semi-circular ball 206 while rotating, so that the filter plate 204 drives the circular plate 202 to slide toward the inner wall of the intake pipe 101, squeezing the first spring 203, causing the first spring 203 to generate a rebound force, and then the filter plate 204 vibrates under the rebound force of the first spring 203, thereby vibrating the impurities in the filter holes inside the filter plate 204 out of the filter holes, so that the filter plate 204 is always in a connected state, and the filter holes inside the filter plate 204 are prevented from being blocked by impurities;

[0033] And under the action of the elastic force of the second spring 303, the connecting column 301 drives the block 3 to be below the air outlet pipe 208, so that the exhaust gas inside the spiral tube 102 stays inside the spiral tube 102, thereby increasing the time for the exhaust gas to heat the water outside the spiral tube 102, and when the air inlet pipe 101 continues to input exhaust gas into the spiral tube 102, the air pressure inside the spiral tube 102 increases, thereby causing the gas to drive the block 3 to move upward inside the connecting tube 207. At this time, the second spring 303 is squeezed to generate a rebound force, until the block 3 moves to the top of the air outlet pipe 208, the gas inside the spiral tube 102 is discharged, the air pressure is reduced, and under the action of the elastic force of the second spring 303, the block 3 returns to its original position, which can increase the time for the exhaust gas to stay inside the spiral tube 102, thereby increasing the time for the exhaust gas to heat the water, so as to enhance the utilization rate of the exhaust gas.
