Technical Field

[0001] The present invention relates to the technical field of industrial safety, and specifically provides an industrial safety device integrating dust removal and fire prevention functions. Background Art

[0002] The raw materials of cotton textile mills are mostly flammable items such as cotton and chemical fibers. In the preparatory spinning workshop, fire hazards or fire accidents are often caused by metal sparking of equipment, lint formation on the fan impeller, friction ignition of the wall panel inlay, aging and needle connection ignition of the card clothing, improper configuration and use of the card clothing, etc. After a fire breaks out in the blowing and carding equipment, the burning cotton will reach the dust filter chamber along with the negative pressure air flow. The dust filter chamber has no fire alarm detection function and cannot give an early warning in the first place, resulting in heavy losses. The industrial safety device integrating dust removal and fire prevention functions is a comprehensive safety system designed for the industrial environment, aiming to solve the problems of floating cotton control and fire prevention in the workplace at the same time.

[0003] The patent with the publication number CN219032491U discloses a carding machine dust filter unit that is convenient for cleaning. It is provided with a first dispersing wheel and a second dispersing wheel driven by a driving end to rotate in opposite directions, which can use the louver on it to disperse and knock down the dust in the ventilation, and the sedimentation tank can sediment the impurities in the air. Subsequently, the driving end operates to drive the screen to move up to extract the sediment, reducing the impurities in the discharged air and facilitating the subsequent cleaning of the sediment, bringing convenience to the work of the staff. However, when the existing dust filter unit is in use, its dust filter chamber has no fire alarm detection function, so it is impossible to detect and alarm the burning cotton in the factory workshop.

A double-shaft motor 20 is fixedly installed at the middle position of the top groove body 19. Both output ends of the double-shaft motor 20 are fixedly connected with horizontal screw rod shafts 21 penetrating through the top groove body 19.

The two groups of sliding plates 22 are both located inside the top groove body 19. The two groups of moving scrapers 24 are both located inside the dust suction pipe 3. And the two groups of moving scrapers 24 and the two groups of sliding plates 22 are symmetrically arranged with respect to the double-shaft motor 20.

[0042] Specifically, by starting the dual-axis motor 20 on the top groove body 19, the two transverse screw shafts 21 are driven to rotate together, so that the two sliding plates 22 are driven to move relatively along the top groove body 19 under the cooperation of the symmetric external threads and the moving screw holes 23, and then the two moving scraping plates 24 are driven to move relatively along the dust suction pipe 3 until the cotton wool in the dust suction pipe 3 is pushed into the top of the dust conveying pipe 4.

This can prevent the inhaled cotton wool from adhering to and accumulating on the inner walls of the dust suction pipe 3 and the dust conveying pipe 4, which affects the dust suction force of the device, significantly improves the dust suction efficiency of the device, and ensures the detection accuracy of the burning cotton.

[0043] As an implementation manner of the present invention, referring to Figure 1 , Figure 2 , Figure 8 , Figure 9 , a filter screen 36 is arranged on the lower surface of the device main body 1. A rotating shaft 38 penetrates through the middle position of the filter screen 36 movably. Four rotating scraping rods 39 are fixedly connected to the top of the rotating shaft 38. A water storage tank 34 is arranged below the device main body 1. A cover plate 35 with an opening is fixedly connected to the upper end of the water storage tank 34, and the device main body 1 is located on the upper surface of the cover plate 35 with an opening. A booster pump 40 is fixedly installed at the middle position of the inner bottom of the water storage tank 34.

[0044] A rotating motor 37 is fixedly installed at the middle position of the lower surface of the filter screen 36, and the rotating shaft 38 passes through the filter screen 36 and is fixedly connected to the output end of the rotating motor 37. The four rotating scraping rods 39 are equidistantly distributed on the upper surface of the filter screen 36, and the shapes of the four rotating scraping rods 39 are all arc-shaped.

[0045] Clear water is arranged inside the water storage tank 34. The shapes of the four connecting pipes 43 are all U-shaped, and the upper and lower ends of the connecting pipes 43 penetrate through the outer sides of the device main body 1 and the water storage tank 34 respectively.

A plurality of spray pipes 45 are equidistantly distributed on the lower surface of the annular pipe 44, and the annular pipe 44 is attached to the inner side wall of the device main body 1.

[0046] Specifically, by starting the booster pump 40 at the bottom inside the water storage tank 34, the clear water inside the water storage tank 34 is respectively introduced into the interiors of the four groups of connecting pipes 43 through the cooperation of the water suction pipe 41 and the drain pipe 42. Then, through the four groups of connecting pipes 43, the clear water is introduced into the interior of the annular pipe 44, and through a number of spray pipes 45, the clear water is evenly sprayed into the interior of the device main body 1. Next, start the rotary motor 37 on the lower surface of the filter net 36 to drive the rotating shaft 38 to rotate, thereby driving the four groups of rotary scraping rods 39 to rotate together. Furthermore, the clear water is filtered back into the interior of the water storage tank 34 without obstruction, which can quickly extinguish the ignited cotton inside the suction device and can reuse the clear water, ensuring the service life of the device and saving water resources at the same time.

[0047] Working principle: First, the operator starts the drive motor 6 on the top cover plate 2 to drive the vertical threaded shaft 7 and the driving gear 12 to rotate together. Thus, through the threaded connection between the vertical threaded shaft 7 and the lifting plate 8 and the cooperation of the limiting vertical rod 9 and the lifting slide hole 11, the lifting plate 8 is driven to move upward. Furthermore, under the cooperation of the movable ring 17 and the movable groove 18, the dust conveying pipe 4 and the dust suction pipe 3 are driven to move upward together. At the same time, the rotation of the driving gear 12 and the rotating ring 14 will drive the driven gear 13 engaged with it to rotate. Thus, through the cooperation of the first limiting block 15 and the first limiting groove 16 and the movable ring 17 and the movable groove 18, the dust conveying pipe 4 is driven to rotate, and then the dust suction pipe 3 is driven to rotate. At the same time, the air extraction fan 5 is started, and in cooperation with the fire alarm 25 (model: AMP-119F) and the buzzer 28, it can detect the fire of the inhaled cotton wool while removing dust from different positions around the device, preventing a fire accident caused by burning cotton in the factory workshop, significantly improving the detection range and safety. Moreover, the detection effect of full coverage can be achieved through the opposed shooting mode of the two groups of fire alarms 25. Secondly, by starting the double-shaft motor 20 on the top groove body 19 to drive the two horizontal screw shafts 21 to rotate together. Thus, under the cooperation of the symmetric external threads and the moving screw holes 23, the two sliding plates 22 are driven to move relatively along the top groove body 19, and then the two moving scrapers 24 are driven to move relatively along the dust suction pipe 3 until the cotton wool in the dust suction pipe 3 is pushed to the top of the dust conveying pipe 4. Then, the lifting motor 29 at the top inside the dust suction pipe 3 is started to drive the vertical screw shaft 30 to rotate. Thus, through the threaded connection between the vertical screw shaft 30 and the lifting push plate 31 and the cooperation of the two groups of second limiting blocks 32 and the two groups of second limiting grooves 33, the lifting push plate 31 is driven to move downward, and then the cotton wool is pushed into the interior of the device main body 1. This can prevent the inhaled cotton wool from adhering and accumulating on the inner walls of the dust suction pipe 3 and the dust conveying pipe 4, affecting the dust suction force of the device, significantly improving the dust suction efficiency of the device, and ensuring the detection accuracy of the burning cotton. Finally, when a fire alarm occurs, by starting the booster pump 40 at the bottom inside the water storage tank 34, the clear water in the water storage tank 34 is respectively introduced into the four connecting pipes 43 through the cooperation of the water extraction pipe 41 and the drain pipe 42. Then, through the four connecting pipes 43, the clear water is introduced into the annular pipe 44, and through a number of spray pipes 45, the clear water is evenly sprayed into the interior of the device main body 1. Then, the rotation motor 37 on the lower surface of the filter screen 36 is started to drive the rotating shaft 38 to rotate. Thus, the four rotating scraping rods 39 are driven to rotate together, and then the clear water can be filtered back into the water storage tank 34 unobstructed. This can quickly extinguish the burning cotton inhaled into the device interior and can reuse the clear water, ensuring the service life of the device and saving water resources at the same time, and completing the operation.
