Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explanation of the present invention and is not to be construed as limiting the present invention, and modifications to the present embodiment, which may not creatively contribute to the present invention as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present invention.
As shown in fig. 1-3, the pneumatic cleaning device of the DPF cleaning machine comprises a pneumatic assembly for providing gas to drive the pneumatic cleaning device to work, and the pneumatic assembly comprises a fixed box 1. The middle part of the fixed box 1 is sleeved with a control shaft 2, and the top of the control shaft 2 is provided with a high-pressure air inlet pipe 3. The control shaft 2 bottom one side fixedly connected with second belt pulley 4, second belt pulley 4 cooperation have belt 5, and the belt 5 opposite side cooperation has first belt pulley 6, and first belt pulley 6 fixedly connected with pneumatic step motor 7. The second belt pulley 4 of the control shaft 2 is fixedly connected with a fixed plate 8, and the fixed plate 8 is fixedly connected with an air ejector tube 9. The air ejector 9 is fixedly connected with a pneumatic valve 10, and the pneumatic valve 10 is fixedly connected with an air storage box 11. The gas storage box 11 is fixedly connected with a high-pressure gas pipe 12. The high-pressure air pipe 12 is connected with the residual high-pressure air inlet pipe 3. High-pressure gas is supplied into the control shaft 2 through the high-pressure gas inlet pipe 3. The high-pressure gas enters the air injection pipe 9 through the control shaft 2, and the air injection assembly carries out high-pressure air injection on the DPF to blow out the particles attached to the DPF.
The high-pressure gas enters the gas storage box 11 through the high-pressure gas pipe 12, and the gas in the gas storage box 11 is kept in a high-pressure state, so that the gas pressure of the output gas injection pipe 9 is kept stable. The absence of the gas storage box 11 results in high-pressure gas entering directly into the gas lance 9. When high-pressure gas in the gas spraying pipe 9 is blown out, a vacuum state exists between the high-pressure gas pipe 12 and the inside of the gas spraying pipe 9 for a certain time, and a certain time is needed for subsequent high-pressure gas filling, so that the pressure of the gas blown out of the gas spraying pipe 9 is unstable, and the cleaning effect is affected.
One side of the fixed plate 8 is provided with a guide rail 13, and the guide rail 13 is connected with a sliding block 14 in a matching sliding way. The slide block 14 is fixedly connected with a pneumatic stepping motor 15. A gear (not shown) is fixedly arranged at the bottom of one side of the pneumatic stepping motor 15, and the gear is meshed with a gear rod 16. Wherein the gear lever 16 is fixedly connected with the fixing plate 8. When the pneumatic stepping motor 15 works, the gear is driven to rotate. The gear rotation moves the gear lever 16. The gear rod 16 moves to drive the fixed plate 8 to move, so that the air ejector 9 is driven to move for a certain distance along the direction of the guide rail 13, and the purpose of adjusting the position of the air ejector 9 is achieved.
Preferably, the control shaft 2 is connected with a moving plate 17 through a bearing. The moving plate 17 is abutted with two pistons 18, and the pistons 18 are fixedly connected with a cylinder. 19
The working process comprises the following steps:
as shown in the figure, in the case of the whole machine, the DPF is placed on the whole machine of the DPF cleaning machine. At this time, when the pneumatic cleaning device starts to operate, the position of the air jet pipe 9 is adjusted to the position of the outer edge of the DPF by the high-pressure stepping motor, and then the gas is introduced. The gas enters the control shaft 2 through the high pressure inlet pipe 3. The gas in the control shaft 2 enters the gas storage box 11 along the high-pressure gas pipe 12. The pressure is kept stable by the gas storage box 11, and high-pressure gas in the gas storage box 11 enters the gas spraying pipe 9 through the pneumatic valve 10, so that the gas is sprayed out to impact the upper surface of the DPF, and the particulate matters on the inner surface of the DPF are separated from the DPF. At the same time, the pneumatic stepping motor 7 drives the first pulley 6 to rotate. The first pulley 6 moves the belt 5 and thus the second pulley 4. The second belt pulley 4 rotates to drive the control shaft 2 to rotate. When the control shaft 2 rotates, the air spraying pipe 9 is positioned at the outer edge of the DPF and is not positioned at the center, so that the air spraying pipe 9 rotates around the center for one circle around the outer edge of the DPF, and the outer ring of the DPF is cleaned. After one rotation, the pneumatic stepping motor 7 reverses to prevent the high-pressure air pipe 12 from knotting.
Then, the pneumatic stepping motor 15 works to drive the gear to rotate. The gear wheel rotates to drive the gear rod 16 to move, so that the fixed plate 8 is driven to move by a certain distance, and the distance is smaller than the diameter of the air injection pipe 9. The fixed plate 8 moves to drive the air jet pipe 9 to move towards the center of the DPF by the same distance. The steps are repeated, and the pneumatic stepping motor 7 drives the air spraying pipe 9 to rotate around the center of the DPF, so that the inside of the outer edge of the DPF is cleaned at a certain distance. After repeating the above steps a number of times, the surface of the DPF is completely cleaned, and the air lance 9 is located at the center of the DPF.
When the jet pipe 9 jets air each time, the air cylinder drives the moving plate 17 to move upwards for one displacement, so that the jet pipe 9 is not contacted with the surface of the DPF any more, and when the jet pipe 9 rotates for a small angle to clean another position, the air cylinder moves downwards for one displacement, so that the jet pipe 9 is abutted with the DPF for cleaning. By this arrangement, the air lance 9 is prevented from moving when directly contacting the surface of the DPF, abrasion of the air lance 9 is prevented, and the service life of the air lance 9 is prolonged.
The whole effect is as follows:
through the arrangement, the whole cleaning process is completely performed by high-pressure gas, the equipment mechanism is not complex, the DPF can be cleaned in an omnibearing manner, and the whole work is orderly performed under the control of a PLC program. The cleaning solution is not needed to be used for realizing a better cleaning effect, and the cost is lower.
