Description

Technical Field

[0001] The invention relates to the technical field of dust removal devices, and in particular to a textile dust removal device. Background Art

[0002] When textile workers use textile machines to work, a large amount of floc dust will be generated. Most of this dust is very fine natural or artificial fibers. Due to its low density, it will float in the air as the loom runs. If there is no corresponding dust removal device, it will not only affect the quality of textile workmanship, but also endanger the health of the textile workers themselves, and easily cause respiratory infections to the textile workers.

[0003] Traditional dust removal devices mostly use negative pressure machines, pipes, dust hoods and other structures. The dust hood is placed above the loom, and the negative pressure is generated by the negative pressure machine to suck the dust into the dust hood. However, if the sucked air is discharged directly without treatment, it will pollute the air in large quantities and will not meet the air emission standards. If filtering treatment is performed, since the dust contains a large number of long and thin fibers, it will easily clog the relevant filter components. In general, there are many looms in factories, so the dust generated is also large, and the filter components are easily clogged. When clogged, they need to be cleaned, which is not only troublesome but also costly. Therefore, a dust removal and filtering device that can be automatically cleaned can be designed. Summary of the invention

[0004] The object of the present invention is to provide a textile dust removal device, which can automatically clean the filter device, ensure the filtering efficiency and reduce the maintenance cost.

[0005] The present invention is achieved through the following technical solutions: the textile dust removal device of the present invention comprises a dust removal tank which is vertically arranged and opened at the lower end, a cleaning tank connected to the lower end of the dust removal tank, a filter assembly arranged in the dust removal tank, an air inlet pipe connected to the lower end side wall of the dust removal tank, a negative pressure pipe connected to the upper end side wall of the dust removal tank, a negative pressure machine connected to the negative pressure pipe, and a cleaning device arranged in the cleaning tank; the air inlet pipe is connected to a dust hood; the filter assembly comprises a connecting rod vertically arranged in the dust removal tank, a plurality of filter plates arranged on the connecting rod, and a driving device for driving the connecting rod to rise and fall; the plurality of filter plates are distributed in the vertical direction.

[0006] Furthermore, the filter plate includes a fixed block connected to the connecting rod, a fixed ring coaxially arranged with the connecting rod, a plurality of reinforcing rods for connecting the fixed block and the fixed ring, and a filter net laid between the fixed block and the fixed ring.

[0007] Furthermore, the filter plate and the connecting rod are both made of metal; and the connecting rod is connected to an electrostatic generator.

[0008] Furthermore, the driving device includes a pull rope connected to the upper end of the connecting rod, a winding roller arranged on the outer wall of the upper end of the dust removal tank, and a motor connected to the winding roller; the pull rope passes through the upper end wall of the dust removal tank and is wound around the winding roller.

[0009] Furthermore, the inner diameter of the cleaning tank is larger than the inner diameter of the dust removal tank.

[0010] Furthermore, the cleaning device includes an annular cleaning pipe arranged on the inner wall of the cleaning tank, a water supply pipe connected to the cleaning pipe, a first valve arranged on the water supply pipe, a water pump connected to the water supply pipe, and a plurality of nozzles arranged on the inner wall of the cleaning pipe.

[0011] Furthermore, the nozzle is arranged obliquely downward.

[0012] Furthermore, the cleaning device is provided in plurality, and the plurality of cleaning tanks are distributed in the vertical direction.

[0013] Furthermore, a drainage hopper is provided at the lower end of the cleaning tank, and a second valve is provided at the lower end of the drainage hopper.

[0014] The technical solution of the present invention has at least the following advantages and beneficial effects: the textile dust removal device of the present invention, when in use, the negative pressure machine extracts the air in the dust removal tank and the air inlet pipe through the negative pressure pipe, and then absorbs the dust, impurities, etc. generated by the textile machine during operation through the dust hood. The dust, etc. enter the dust removal tank and pass through the filter plate in the dust removal tank. The filter plate can leave the dust, etc., and the cleaned air flows out through the negative pressure pipe. After running for a certain period of time, the driving device drives the filter assembly to descend, so that part of the filter plate enters the cleaning tank, and the cleaning device is used to rinse the several filter plates located below (the power of the negative pressure machine can be appropriately reduced during the cleaning process). The cleaning liquid temporarily stays in the cleaning tank and is discharged uniformly after being stored to a certain amount. Since the several filter plates below undertake most of the filtering work, frequent cleaning of them can effectively ensure the filtering efficiency. After a certain period of time, all the filter plates in the entire filter assembly are lowered to the cleaning tank for cleaning. In this way, there is no need to clean all the filter plates all the time, which can effectively save the cleaning liquid. Moreover, the entire cleaning process does not require complete shutdown, and the filter plate does not need to be taken out for cleaning, thus achieving efficient and manual online cleaning.

[0025] Example

[0026] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 3As shown, the textile dust removal device of this embodiment includes a dust removal tank 11 which is vertically arranged and opened at the lower end, a cleaning tank 14 connected to the lower end of the dust removal tank 11, a filter assembly 20 arranged in the dust removal tank 11, an air inlet pipe 12 connected to the lower end side wall of the dust removal tank 11, a negative pressure pipe 13 connected to the upper end side wall of the dust removal tank 11, a negative pressure machine connected to the negative pressure pipe 13, and a cleaning device 30 arranged in the cleaning tank 14; the air inlet pipe 12 is connected to a dust hood; the filter assembly 20 includes a connecting rod 21 vertically arranged in the dust removal tank 11, a plurality of filter plates 22 arranged on the connecting rod 21, and a driving device 40 for driving the connecting rod 21 to rise and fall; the plurality of filter plates 22 are distributed along the vertical direction. Specifically, when in use, the negative pressure machine extracts the air in the dust removal tank 11 and the air inlet pipe 12 through the negative pressure pipe 13, and then absorbs the dust, impurities, etc. generated by the textile machine during operation through the dust hood. The dust, etc. enter the dust removal tank 11 and pass through the filter plate 22 in the dust removal tank 11. The filter plate 22 can leave the dust, etc., and the cleaned air flows out through the negative pressure pipe 13. After running for a certain period of time, the driving device 40 drives the filter assembly 20 to descend, so that part of the filter plate 22 enters the cleaning tank 14, and the cleaning device 30 is used to rinse the several filter plates 22 located below (the power of the negative pressure machine can be appropriately reduced during the cleaning process). At this time, the several filter plates 22 located in the dust removal tank 11 still have a filtering effect, and the cleaning liquid temporarily stays in the cleaning tank 14, and is uniformly discharged after being stored to a certain amount. Since the several filter plates 22 below undertake most of the filtering work, frequent cleaning of them can effectively ensure the filtering efficiency. After a certain period of time, all the filter plates 22 in the entire filter assembly 20 are lowered to the cleaning tank 14 for cleaning. In this way, it is not necessary to clean all the filter plates 22 all the time, which can effectively save cleaning liquid. In addition, it is not necessary to completely shut down the machine during the entire cleaning process, and it is not necessary to take out the filter plates 22 for cleaning, thus achieving efficient and manual online cleaning.

[0027] The filter plate 22 in this embodiment includes a fixed block 221 connected to the connecting rod 21, a fixed ring 222 coaxially arranged with the connecting rod 21, a plurality of reinforcing rods 223 for connecting the fixed block 221 and the fixed ring 222, and a filter screen 224 laid between the fixed block 221 and the fixed ring 222. The filter plate 22 and the connecting rod 21 are both made of metal; the connecting rod 21 is connected to an electrostatic generator. Specifically, since the dust generated during the textile process is mostly short or long fibers, the filter screen 224 made of metal can well block it. At the same time, the filter plate 22 is continuously charged with static electricity through the electrostatic generator, which can better absorb the dust.

[0028] The driving device 40 in this embodiment includes a pull rope 41 connected to the upper end of the connecting rod 21, a winding roller 42 provided on the outer wall of the upper end of the dust removal tank 11, and a motor 43 connected to the winding roller 42; the pull rope 41 passes through the upper end wall of the dust removal tank 11 and is wound on the winding roller 42. Specifically, the winding roller 42 is driven to rotate by the motor 43 to achieve winding or loosening of the pull rope 41, thereby well driving the filter assembly 20 to rise and fall, wherein since the connecting rod 21 needs to be connected to the electrostatic generator, the relevant wires can be bound together with the pull rope 41.

[0029] In this embodiment, the inner diameter of the cleaning tank 14 is larger than the inner diameter of the dust removal tank 11 .

[0030] The cleaning device 30 in this embodiment includes an annular cleaning pipe 31 provided on the inner wall of the cleaning tank 14, a water supply pipe 32 connected to the cleaning pipe 31, a first valve provided on the water supply pipe 32, a water pump connected to the water supply pipe 32, and a plurality of nozzles 33 provided on the inner wall of the cleaning pipe 31. The nozzles 33 are arranged obliquely downward. Specifically, the water pump delivers the cleaning liquid into the cleaning pipe 31 through the water supply pipe 32, and then sprays the cleaning liquid onto the filter plate 22 through the nozzles 33 to clean the filter plate 22. Since the impurities are basically on the lower surface of the filter plate 22, when the nozzles 33 flush the upper surface of the filter plate 22, it has a backwashing effect, which can better flush the impurities from the filter plate 22.

[0031] In this embodiment, multiple cleaning devices 30 are provided, and multiple cleaning tanks 14 are distributed in the vertical direction. Specifically, multiple cleaning devices 30 can effectively improve the cleaning efficiency, and each cleaning device 30 is independent. When only the several filter plates 22 located at the bottom are cleaned, only the several cleaning devices 30 at the top can be started. When all the filter plates 22 need to be cleaned, all the cleaning devices 30 can be started at the same time.

[0032] In this embodiment, a drain bucket is provided at the lower end of the cleaning tank 14, and a second valve is provided at the lower end of the drain bucket.

[0033] In summary, in the textile dust removal device of this embodiment, when in use, the negative pressure machine extracts the air in the dust removal tank 11 and the air inlet pipe 12 through the negative pressure pipe 13, and then absorbs the dust, impurities, etc. generated by the textile machine during operation through the dust hood. The dust, etc. enter the dust removal tank 11 and pass through the filter plate 22 in the dust removal tank 11. The filter plate 22 can leave the dust, etc., and the cleaned air flows out through the negative pressure pipe 13. After running for a certain period of time, the driving device 40 drives the filter assembly 20 to descend, so that part of the filter plate 22 enters the cleaning tank 14, and the cleaning device 30 is used to rinse the several filter plates 22 located below (the power of the negative pressure machine can be appropriately reduced during the cleaning process). The cleaning liquid temporarily stays in the cleaning tank 14 and is discharged uniformly after being stored to a certain amount. Since the several filter plates 22 below undertake most of the filtering work, frequent cleaning of them can effectively ensure the filtering efficiency. After a certain period of time, all the filter plates 22 in the entire filter assembly 20 are lowered to the cleaning tank 14 for cleaning. In this way, it is not necessary to clean all the filter plates 22 all the time, which can effectively save cleaning liquid. In addition, it is not necessary to completely shut down the machine during the entire cleaning process, and it is not necessary to take out the filter plates 22 for cleaning, thus achieving efficient and manual online cleaning.
