Description

Technical Field

[0001] The present invention relates to the technical field, and specifically to a closed - type carpet transmission dust recovery and purification device. Background Technique

[0002] A carpet is a floor covering made of natural fibers such as cotton, linen, wool, silk, grass or chemical synthetic fiber raw materials, and is woven, tufted or knitted by hand or mechanical processes. It is one of the art and craft categories with a long historical tradition worldwide. Most carpet fabrics have relatively thick warp and weft threads and large gaps, making them prone to dust accumulation and especially lint absorption. Generally, a vacuum cleaner is used for cleaning.

[0003] During the processing and production of carpets, tiny particles such as dust and lint will continuously accumulate on the surface and inside the fibers of the carpet. These accumulations may fly due to friction and extrusion during the winding process, causing air pollution and secondary pollution of the carpet, affecting the processing environment, and dust is very harmful to human health. Therefore, we propose a closed - type carpet transmission dust recovery and purification device to solve the above problems. Summary of the Invention

The baffle plate 22 is installed on the inner wall of the separation box 21, and a transmission box 4 is installed at one end of the baffle plate 22;

[0031] A fixing groove is opened at the top of the dust - settling box 1, and a limiting plate 13 is installed at the top of the fixing groove. The auxiliary transmission mechanism 3 is arranged at the bottom of the limiting plate 13. When it is necessary to transmit and wind the carpet, one end of the carpet can be clamped on the winding shaft 33. The rotation of the winding shaft 33 can drive the carpet to be transmitted inside the dust - settling box 1. With the help of the auxiliary transmission mechanism 3, the carpet can be stretched and cleaned.

[0032] As Figure 5 shown, in order to ensure the separation effect of the device and prevent fluff in the air flow from entering the external air - pressure device along the pipeline, the dust - suction and separation mechanism 2 further includes a dust - settling box 23. The dust - settling box 23 is clamped inside the separation box 21. A gas - transmission plate 231 is arranged on one side of the dust - settling box 23. The gas - transmission plate 231 is installed on one side of the transmission box 4. One end of the gas - transmission plate 231 is provided with a plurality of one - way conveying pipes, and the one - way conveying pipes communicate with the dust - settling box 23. A sedimentation liquid is arranged inside the dust - settling box 23, and the one - way conveying pipes can also play a role in isolation to prevent the back - flow of the sedimentation liquid;

[0033] A fixing cover 25 is installed at the top of the dust - settling box 23 for sealing. A plurality of compression pipes 251 are installed at the bottom of the fixing cover 25.

A grid sieve plate 29 is arranged at the bottom of the fixing frame 26. The grid sieve plate 29 can float below the liquid level under the buoyancy of the fixing frame 26, and can block fluff impurities, etc. in the sedimentation liquid. Moreover, the grid sieve plate 29 can also move with the fixing frame 26 when the air flow stirs the sedimentation liquid, and can reduce the blockage of the grid sieve plate 29 under the action of water flow impact.

[0034] As Figure 6As shown, in order to reduce the situation of wool floc debris with effective rate in the overflowing settling liquid, a plurality of buffer rods 27 are installed inside the fixing frame 26. The buffer rods 27 are rectangular and elastic. The buffer rods 27 are arranged in a uniform array between the fixing frames 26. A plurality of reset balls 28 are clamped inside the buffer rods 27. The reset balls 28 are elastic and annular grooves are formed on the side walls. And a plurality of adsorption plates 281 are installed inside the annular grooves.

The overflowing settling liquid can impact on the outside of the reset balls 28, and can quickly adsorb the internal wool flocs and the like under the action of the adsorption plates 281, making them clamped between the metal hooks, and with the subsequent negative pressure, they are dried and adhered to the metal hooks.

[0035] As Figure 4 shown, during the negative pressure transmission process, some moisture is likely to enter the connecting pipe of the external device along with the air flow. A through groove is provided at the top of the separation box 21, and a sealing plate 24 is clamped inside the through groove. A plurality of transmission pipes 241 are installed on the sealing plate 24. The transmission pipes 241 are connected to the external air pressure device. A plurality of exhaust holes are provided on the fixed cover 25, and sponge blocks can be clamped inside the exhaust holes. The transmission pipes 241 are clamped inside the exhaust holes, and can play a role in moisture absorption under the action of the sponge blocks to prevent the situation of excessive moisture content in the air flow.

[0036] As Figure 3 shown, for the stability of carpet transmission, the auxiliary transmission mechanism 3 includes a clamping frame 31. A pair of welding plates are fixedly connected to the inner wall of the clamping frame 31, and a winding shaft 33 is rotatably arranged between the welding plates. One end of the carpet can be clamped on the winding shaft 33. As the winding shaft 33 rotates, it can pull the carpet to slowly transmit inside the dust reduction box 1.

[0037] As Figure 4 shown, in order to reduce the residue of debris and dust in the carpet, slide rail grooves 32 are clamped on the outer walls at both ends of the clamping frame 31. Sliding plates 34 are movably clamped inside the slide rail grooves 32. Positioning disks 35 are installed on the inner parts of the sliding plates 34. Positioning rings 36 are installed on the inner parts of the positioning disks 35. Slots are formed on the inner walls of the positioning rings 36, and reset insertion rods 361 are inserted inside the slots. The reset insertion rods 361 are arranged in a uniform array inside the positioning rings 36;

[0038] A rotating disk 37 is rotatably provided on the inner wall of the positioning disk 35. Movable insertion rods 371 are inserted on the side walls of both ends of the rotating disk 37. A plurality of connecting rings 38 are clamped on the movable insertion rods 371. The connecting rings 38 are elastic. During the transmission process of the movable insertion rods 371, they can cooperate with and squeeze the bottom of the reset insertion rods 361. When the rotating disk 37 rotates, it can cause the movable insertion rods 371 to squeeze between the reset insertion rods 361 during the circular motion process, so that the movable insertion rods 371 make reciprocating motions during the transmission process, and can continuously pat and clean the pile surface of the carpet, quickly shake off the accumulated dust debris, etc. inside, and cooperate with the air flow to quickly export the dust, etc., to avoid the situation of secondary adsorption on the carpet.

[0039] As Figure 7 shown, during long-term operation, it is easy to have the situation of dust accumulation speed. A card slot is opened on one side of the transmission box 4 close to the dust suction and separation mechanism 2, and the position of the card slot corresponds to the air delivery plate 231. A rectangular frame 41 is clamped on the inner wall of the transmission box 4. An elastic sieve plate 42 is installed inside the rectangular frame 41. The cross-section of the elastic sieve plate 42 is wavy. A plurality of counterweight shafts 43 are fixedly connected to the elastic sieve plate 42. A plurality of annular grooves are opened on the counterweight shafts 43, and elastic sheets are clamped inside the annular grooves. Under the action of the air flow, the elastic sheets can swing under the action of the air flow, thereby driving the elastic sieve plate 42 to swing. The elastic sieve plate 42 can squeeze and shake off the adsorbed air guiding dust impurities, etc. on the surface, preventing blockage during the diversion and transmission process.

[0040] Preferably, a transmission slot is opened on the surface of the dust reduction box 1, and a positioning plate 11 is provided at the bottom of the transmission slot. A pair of vertical plates are installed on the positioning plate 11, and a transmission rod is rotatably provided between the vertical plates. Clamping shafts 12 are installed on the side walls at both ends of the dust reduction box 1. A transmission roller 14 is provided between the clamping shafts 12. The transmission roller 14 penetrates the side wall of the dust reduction box 1 and is rotatably arranged between the clamping shafts 12. Under the combined action of the transmission roller 14 and the clamping shafts 12, the transmission position of the carpet can be restricted, ensuring smooth transmission of the equipment, and also being able to keep away from the subsequent dust cleaning position, reducing the situation of a large amount of secondary dust adsorption.

[0041] Working principle: First, when it is necessary to transmit and wind up the carpet, one end of the carpet can be clamped on the winding shaft 33. The rotation of the winding shaft 33 can drive the carpet to be transmitted inside the dust reduction box 1. With the help of the auxiliary transmission mechanism 3, the carpet can be stretched and cleaned. Under the action of an external air pressure device, the dust inside the dust reduction box 1 can be conducted along the transmission box 4 and the dust suction and separation mechanism 2 and discharged under negative pressure. And the dust suction and separation mechanism 2 can filter and clean dust debris, etc. During the transmission of the carpet, it can be positioned under the action of the rotating roller and the transmission roller 14. And before being wound around the winding shaft 33, it can contact the plush surface of the carpet with the help of the movable insertion rod 371 and the connecting ring 38, and can play a role in cleaning and carding the plush during the transmission process. And as the movable insertion rod 371 moves in a circular motion, the reset insertion rods 361 can be squeezed, so that the movable insertion rod 371 makes a reciprocating motion during the transmission process, and can continuously pat and clean the plush surface of the carpet, quickly shaking off the dust debris and the like accumulated inside;

[0042] Then, under the action of an external air pressure device, the inside of the dust reduction box 1 can be quickly led out along the transmission box 4 and the dust suction and separation mechanism 2. And under the action of the airflow, the elastic sheet can swing under the action of the airflow, thereby driving the elastic sieve plate 42 to swing, preventing blockage during the diversion and transmission process;

[0043] Finally, after the airflow enters the dust reduction box 23, the fluff debris, etc. inside can be quickly separated under the action of the sedimentation liquid, playing a role in sieving and cleaning. And when the bottom sedimentation liquid flows under the action of the airflow during the separation process, when part of the sedimentation liquid and fluff pass through the mesh sieve plate 29, the adsorption plate 281 on the outer wall of the reset ball 28 can collect and adsorb the excess fluff, etc. in the sedimentation liquid, preventing it from entering the connecting pipe of the external air pressure device along the airflow.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
