Description

Technical Field

[0001] The utility model relates to the technical field of on-site dust collection equipment, in particular to an on-site dust collection device for safety evaluation. Background Art

[0002] Safety evaluation refers to the process of evaluating the on-site working environment. Through safety evaluation, safety hazards in the production environment can be identified, evaluated and fed back, which can prevent dangers or reduce the occurrence of accidents. After the safety evaluation, reasonable suggestions and solutions can be provided to the construction unit to ensure the smooth progress of the project.

[0003] When conducting a safety assessment of on-site dust, staff are required to collect the dust on-site, which will be affected by the dust collection device. The dust collection device is internally installed with components such as a fan and a filter cartridge. The dust in the air sucked in by the fan will be collected into the interior of the device under the action of the filter cartridge, which can assist the collection work. However, when it is in use, the surface of the filter cartridge will continuously absorb dust, and the dust will cause clogging of the mesh holes on the filter cartridge. When the staff uses a scraper to clean it, the dust scraped off by the scraper will continue to be adsorbed on the filter cartridge under the influence of wind force, and the cleaning efficiency is not high. In order to solve this technical problem, the utility model proposes an on-site dust collection device for safety assessment. Utility Model Content

[0004] The main purpose of the utility model is to provide an on-site dust collection device for safety evaluation, which can effectively solve the problems mentioned in the background technology.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model cooperates between the fixed rope, the scraper and the No. 1 spring, and pulling the fixed rope can drive the two groups of scrapers to move and contact. At this time, the two groups of scrapers will be spliced ​​into a circle. When cleaning, the two groups of scrapers can scrape the dust on the filter cartridge. The fixed ring drives the scraper to move inside the fixed cartridge to drive the dust collected by the scraper to move. The cleaned dust will move with the scraper, and the cleaned dust will not continue to be adsorbed on the cleaned filter cartridge. When the scraper is moved in the reverse direction, the two groups of scrapers will be controlled to move in the reverse direction under the control of the No. 1 spring. At this time, the scraper will break away from the contact with the filter cartridge, which is convenient for moving the scraper to the top position of the fixed cartridge, thereby realizing the function of the scraper to effectively clean the filter cartridge, which is beneficial to improving the efficiency during cleaning and collection.

[0015] In the utility model, components such as the No. 2 spring are provided, so that when the fixing ring moves toward the inside of the fixing tube, the No. 2 spring is squeezed and the pressure is stored. When the control frame is not subjected to pressure, the No. 2 spring can push the fixing ring to automatically reset, which is convenient for the staff to operate, and the dust cleaned by the scraper can be collected through the collection box.

[0025] A fixing plate 3 is fixedly installed on the inner wall of the fixing cylinder 1, and a filter cartridge 4 is installed on the outer surface of the fixing plate 3. The filter cartridge 4 can be installed and limited by the fixing plate 3, and the mounting seat of the filter cartridge 4 is fixed to the outside of the fixing plate 3 by multiple sets of fixing bolts.

[0026] A limiting rod 5 is installed on one side of the fixed plate 3, and the outer surface of the limiting rod 5 is slidably connected with a fixing ring 6, and the moving direction of the fixing ring 6 can be limited by the limiting rod 5. The outer surface of the fixing ring 6 is slidably connected to the inner wall of the fixed cylinder 1, and a No. 2 spring 16 is sleeved on the outside of the limiting rod 5, and one end of the No. 2 spring 16 is connected to the outer surface of the fixing ring 6, and the other end of the No. 2 spring 16 contacts the outer surface of the filter cartridge 4 mounting seat. One end of the limiting rod 5 is detachably connected with a baffle 17, and the No. 2 spring 16 can push the fixing ring 6 to automatically move to the outside of the fixed cylinder 1, and can automatically adjust its own position when the fixing ring 6 is not subjected to external force.

[0027] A control frame 7 is fixedly mounted on the outer surface of the fixing ring 6 , and the fixing ring 6 can be pushed to move by the control frame 7 . After the No. 2 spring 16 pushes the fixing ring 6 , the top end of the control frame 7 will stay outside the fixing tube 1 .

[0028] A mounting plate 8 is fixedly mounted on the outer surface of the fixing ring 6, and a support rod 9 is slidably connected to the inside of the mounting plate 8. A No. 1 spring 10 is sleeved on the outside of the support rod 9, and a connecting plate 11 is fixedly mounted on one end of the support rod 9. A scraper 12 is fixedly mounted on the outer surface of the connecting plate 11. Two groups of scrapers 12 are arranged and are symmetrical to each other. One end of the No. 1 spring 10 is connected to one side of the mounting plate 8, and the other end of the No. 1 spring 10 is connected to one side of the connecting plate 11. When the scrapers 12 are not subjected to external force, they will move away from each other under the pull of the No. 1 spring 10.

[0029] A fixing rope 13 is installed at one end of the connecting plate 11, and the connecting plate 11 can be pulled to move by the fixing rope 13. At this time, the two groups of scrapers 12 will contact and be spliced ​​into a circular ring. The outer surfaces of the two groups of scrapers 12 are in contact with the outer surface of the filter cartridge 4. When the fixing ring 6 is moved, the scraper 12 can clean the dust on the filter cartridge 4 and drive the cleaned dust to move toward the inside of the fixed cylinder 1.

The dust scraped by the scraper 12 will enter the interior of the collecting box 20 under the push of the fixed ring 6 and the scraper 12, which is convenient for the staff to handle.

[0032] When in use, the two groups of scrapers 12 will move away from each other under the pull of the No. 1 spring 10. At this time, the various positions of the filter cartridge 4 work normally and can absorb dust in the air. When cleaning and collecting, pull the movable plate 18, and the movable plate 18 will pull one end of the fixed rope 13 to move and drive the two groups of scrapers 12 to move. At this time, the two groups of scrapers 12 will contact and form a circular ring. The control frame 7 pushes the fixed ring 6 to move and can drive the scraper 12 to move toward the inside of the fixed cylinder 1. The scraper 12 can clean the dust in the filter cartridge 4 and push the cleaned dust to move. The cleaned dust will be collected in the collection box 20. When the control frame 7 is not pushed, the No. 2 spring 16 can push the fixed ring 6 to reset. When the scraper 12 moves, the No. 1 spring 10 will drive the two groups of scrapers 12 away, and the inside of the fixed ring 6 will open.
