Description

Technical Field

[0001] This utility model relates to the field of gas purging technology, and in particular to a multi-point gas purging device. Background Technology

[0002] Multi-point air sweeping usually refers to using airflow to work at multiple points. An air sweeping device is a device that uses high-pressure gas to blow, clean, and prevent clogging of a specific object. For example, high-pressure air sweeping is performed on the device to be cleaned by combining high-pressure gas and a metal impact head to prevent materials from sticking to the wall and arching.

[0003] A multi-point air sweeping device typically consists of an air source supply device, a multi-channel distribution component, connecting pipes, and actuators at the sweeping points. During operation, the air source device generates a high-pressure airflow, which is precisely distributed to each pipe through the multi-channel distribution component. The actuators guide the airflow to the corresponding points according to a preset program. In pneumatic conveying scenarios, it propels the flow of materials; in gas sampling, it extracts gas samples; and in sweeping scenarios, it blows away dust and foreign objects, thus achieving efficient air sweeping at multiple points.

[0004] In the existing technology, some multi-point air sweeping devices have limited cleaning coverage due to the difficulty in adjusting the direction of the nozzles. This makes it difficult to thoroughly clean complex shapes and corners, easily resulting in cleaning dead spots. Furthermore, it is difficult to flexibly adjust the airflow direction according to different cleaning scenarios and the location of the device to be cleaned, thereby reducing cleaning efficiency and effectiveness. Therefore, a multi-point air sweeping device is proposed to solve the above problems. Utility Model Content

[0013] Reference Figure 1 and Figure 4The collection mechanism 3 includes a collection box 31, which is used to collect debris and other waste that falls during cleaning. A door 32 is rotatably connected inside the collection box 31. The door 32 can rotate around a connecting shaft to open and close the collection box 31. A retaining ring 33 is fixedly connected to the front exterior of the door 32. A plug 34 is slidably connected to the outside of the retaining ring 33. The retaining ring 33 engages with the plug 34 to lock and unlock the door 32. A limiting ring 35 is fixedly connected to the outside of the plug 34 to limit the sliding range of the plug 34 and prevent it from sliding excessively and disengaging from the retaining ring 33. A hollow tube 36 is fixedly connected to the top of the plug 34. The hollow tube 36 provides a sliding channel for the sliding tube 37. The sliding tube 37 is slidably connected inside the hollow tube 36. The sliding tube 37 can slide inside the hollow tube 36. With the help of the spring 38, the plug 34 can slide elastically. A spring 38 is provided on the adjacent side of the two plugs 34. The spring 38 is used to provide a restoring force for the plug 34. The outside of the spring 38 is sleeved on the outside of the sliding tube 37. A handle 39 is fixedly connected to the outside of the plug 34. The handle 39 is convenient for the operator to squeeze and drive the plug 34 to slide to unlock the door 32. Specifically, the collection box 31 is used to collect blown debris. Squeezing the handle 39 causes the plug 34 to slide. The sliding tube 37 moves inside the hollow tube 36 and compresses the spring 38. Pulling out the plug 34 from the collection box 31 unlocks the box door 32. The limiting ring 35 is used to prevent the plug 34 from disengaging from the retaining ring 33. After releasing the handle, the spring 38 returns to its original position and causes the plug 34 to engage, thus enabling convenient opening and closing of the box door 32.

[0014] The implementation principle of this application embodiment is as follows: First, the product to be cleaned is placed on the upper end of the collection box 31. Then, the cylinder 5 is turned on, and the connecting plate 1 drives the rotating mechanism 2 to descend, so that the isolation shell 21 covers the product to be cleaned. Then, the motor 222 is turned on, and the motor 222 drives the drive block 23 to drive the gear 1 24 to rotate. Since the gear 1 24 meshes with the gear 26, the gear 26 drives the force transmission mechanism 25 to rotate. Since the ball outside the driven rod 27 rotates inside the force transmission mechanism 25, the square ring 28 swings back and forth. The square ring 28 rotates inside the ring frame 29. Therefore, the force transmission mechanism 25 can drive the multi-head air pipe 2103 to rotate, which improves the blowing efficiency. The debris blown off falls through the mesh screen at the top of the collection box 31. When it is necessary to clean the debris, squeeze the handle 39 to compress the spring 38, causing the sliding tube 37 to slide inside the hollow tube 36, so that the plug 34 slides out of the collection box 31. Then, pull the handle 39 outward to open the box door 32 and clean the debris inside the collection box 31. During the sliding of the plug 34, the limiting ring 35 limits the plug 34, so that it can only slide between the two retaining rings 33.

[0015] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
