Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction cylinders, in particular to a dust reduction cylinder with a filtering function. Background Art

[0002] A dust suppression cylinder refers to a device that collects dust particles in the air. This device is usually used in the process of environmental monitoring. Its main function is to capture dust particles in the air, such as dust, smoke, etc., for subsequent analysis and detection. By collecting the air through the dust suppression cylinder, samples of suspended particulate matter in the atmosphere can be obtained, providing basic data for subsequent analysis and detection. By collecting and detecting these particles, the air quality status can be understood, and the presence of pollutants can be monitored, so that appropriate measures can be taken to protect the environment and human health.

[0003] At present, the existing device (such as patent number: CN218208793U) discloses an integrated dust suppression cylinder lifting structure. The device can adjust the height of the device at will to adapt to different working environments by setting a lifting mechanism. Then, a plurality of toggle rods are used to rotate the baffle plate and the rotating rod. The rotating rod can drive the screw to rotate. Under the cooperation between the screw and the two threaded sleeves, the two threaded sleeves can drive the support pipe 1 and the support pipe 2 to rise synchronously. Since the thread has self-locking properties, the dust suppression cylinder can be supported to the specified position after the support mechanism is adjusted.

[0004] However, during the implementation of the above technical solution, it was found that there are at least the following technical problems: when the device collects dust particles in the wild, it is unable to filter the dust reduction cylinder, which will cause some fallen leaves and mosquitoes and flies to easily enter the dust reduction cylinder during collection, making the final monitoring results distorted or inaccurate, and the practicality needs to be improved.

In addition, by arranging a guide ring groove and a circular ring, a guiding effect can be provided when installing the filter assembly, which is convenient for positioning the filter frame, and by pulling the L-shaped blocks toward the outside of the clamping grooves on the dust reduction cylinder body, the L-shaped blocks slide in the L-shaped through grooves and stretch the reset spring. At the same time, the L-shaped blocks will drive the sliding block and the limiting block to slide in the sliding groove and the limiting groove respectively, until the distance between the two clamping blocks is greater than the outer diameter of the dust reduction cylinder body, thereby completing the installation and disassembly of the filter assembly, which is convenient for subsequent maintenance.

[0025] Example

[0026] like Figure 1-Figure 4 As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that the existing device is not practical enough. The overall idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides a dust suppression cylinder with a filtering function, comprising a dust suppression cylinder body 11, a guide ring groove 12 is provided inside the dust suppression cylinder body 11, and clamping grooves 13 are symmetrically provided on the circumferential surface of the dust suppression cylinder body 11, and the two clamping grooves 13 are both located below the guide ring groove 12;

[0028] A filtering mechanism is provided at the upper end of the dust suppression cylinder body 11;

[0029] The filtering mechanism includes a filtering assembly 14, a filter frame 15 is fixedly installed on the outer side of the filtering assembly 14, a circular ring 16 is fixedly installed on the lower end of the filter frame 15, and the circular ring 16 is adapted to the guide ring groove 12. The filtering mechanism also includes a fixing block 17, a slide groove 18, a limiting groove 19, an L-shaped through groove 21, a return spring 22, a limiting block 23, a slider 24, an L-shaped block 25 and a clamping block 26. By arranging the filtering assembly 14 on the dust reduction cylinder body 11, it is possible to avoid that non-target particles such as leaves or some mosquitoes and flies are mistakenly caught when collecting dust particles, and ensure that only target particles can pass through, thereby improving the capture efficiency of the dust reduction cylinder body 11 and further improving the practicality. In addition, by arranging the guide ring groove 12 and the circular ring 16, a guiding effect can be provided when the filtering assembly 14 is installed, which facilitates the positioning of the filter frame 15.

[0030] The two fixed blocks 17 are both fixedly installed at the upper end of the filter frame 15, the two slide grooves 18 are both opened inside the fixed block 17, each set of limit grooves 19 is opened on the inner wall of the slide groove 18, the two L-shaped through grooves 21 are both opened on the side wall of the slide groove 18, the two L-shaped through grooves 21 are both located on the outside of the slide groove 18, the two reset springs 22 are both fixedly installed on the side wall of the slide groove 18, each limit block 23 is slidably installed inside the limit groove 19, the two sliders 24 are fixedly installed between the limit blocks 23, the two sliders 24 are fixedly installed with the ends of the reset springs 22, the two sliders 24 are slidably installed with the slide groove 18, and the two L-shaped blocks 25 are located at the slider 24 away from the reset The two L-shaped blocks 25 are fixedly installed on the side wall on one side of the spring 22, and the two L-shaped blocks 25 are slidably installed with the L-shaped through groove 21. The two clamping blocks 26 are located on the side wall of the L-shaped block 25 and are fixedly installed. The two clamping blocks 26 are adapted to the clamping groove 13. By pulling the L-shaped blocks 25 toward the outside of the clamping groove 13 on the dust reduction cylinder body 11, the L-shaped blocks 25 slide in the L-shaped through groove 21 and stretch the reset spring 22. At the same time, the L-shaped block 25 will drive the slider 24 and the limit block 23 to slide in the slide groove 18 and the limit groove 19 respectively, until the distance between the two clamping blocks 26 is larger than the outer diameter of the dust reduction cylinder body 11, thereby completing the installation and disassembly of the filter assembly 14, which is convenient for subsequent maintenance.

[0031] Working principle:

[0032] The first step is to place the dust removal cylinder body 11 as a whole at the outdoor location where dust particles need to be collected during use. Then, the dust removal cylinder body 11 can be picked up and the L-shaped blocks 25 can be pulled toward the outer sides of the clamping grooves 13 on the dust removal cylinder body 11, so that the L-shaped blocks 25 can slide in the L-shaped through grooves 21 and stretch the return spring 22. At the same time, the L-shaped blocks 25 will drive the slider 24 and the limit block 23 to slide in the slide groove 18 and the limit groove 19 respectively, until the distance between the two blocks 26 is larger than the outer diameter of the dust removal cylinder body 11. Then, the dust removal cylinder body 11 can be placed as a whole above the guide ring groove 12 and the circular ring 16 needs to be aligned with the guide ring groove 12 and inserted. Then, the L-shaped block 25 can be loosened, so that the return spring 22 is reset and drives the block 26 to be clamped into the clamping groove 13 to complete the installation of the filter assembly 14 and achieve the filtering of the dust removal cylinder body 11.

[0033] In the second step, when the dust particles are collected, the dust reduction cylinder body 11 can be brought into the working room, and then the L-shaped blocks 25 can be pulled toward the outside of the clamping grooves 13 on the dust reduction cylinder body 11, so that the distance between the two clamping blocks 26 is larger than the outer diameter of the dust reduction cylinder body 11, and then the filter assembly 14 can be directly picked up as a whole, and then the dust particles at the bottom of the dust reduction cylinder body 11 can be detected, and the filter assembly 14 can be cleaned as a whole.

[0034] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
