Description
Technical Field
The invention belongs to the field of air draft devices of hosiery machines, and particularly relates to a dust absorption and noise reduction device for continuous working of the hosiery machine and a using method thereof.
Background
The hosiery machine produces a lot of waste silk and dust in the production process, and needs to be cleaned continuously, otherwise, the hosiery machine can work abnormally and cause workshop pollution. At present, a factory adopts a waste silk box to treat waste silk and dust; the waste silk box is provided with a cleaning door, a waste silk inlet and an air outlet, the waste silk inlet is provided with an air pipe, the end part of the air pipe is connected with a plurality of air suction pipelines, the air suction pipelines are connected with the hosiery machines, namely, one waste silk box is simultaneously connected with a plurality of hosiery machines, the waste silk box is internally provided with a fan and a frequency converter, the air suction end of the fan is connected with the waste silk inlet, the air exhaust end of the fan is positioned in the waste silk box, and the air outlet is provided with a filter screen; after the fan started through the effect of converter, waste silk and the dust that the hosiery machine produced entered into the waste silk incasement through the pipeline of breathing in, branch pipe and waste silk entry, before the waste silk of waste silk incasement was full of, the workman opened the clearance door and cleared up waste silk and dust. When the workman cleared up waste silk and dust in the waste silk incasement, need close the fan, corresponding hosiery machine can not carry out work again, also need close, the time of clearance waste silk and dust is about 10min, after clearing up, close the clearance door, restart fan, because the fan is frequency conversion start, the start-up speed is slower, need 20min just can the complete start-up, lead to the down time of hosiery machine long, once shut down and need 30min just can restart resume production. Aiming at different raw materials of the stocking yarn used by the stocking machine, the number of times of stopping the stocking machine every day is different from 1 to 3, the frequent times are more, and the production efficiency of the stocking machine is seriously reduced.
In order to reduce the number of times of shutting down of hosiery machine, the workman just can clear up when the silk waste case is deposited soon fully usually, and the silk waste and the dust that the silk waste case internal average was deposited are more in quantity, and the windage is big, leads to fan load to increase, energy consumption increase, noise grow.
In addition, the in-process that the waste silk got into and left the waste silk case passes through the fan, with the impeller contact of fan, leads to a large amount of waste silks to twine in the impeller, and the impeller is out of balance, and wearing and tearing aggravation leads to the life of fan to reduce, needs often to change the fan, leads to the maintenance frequency of equipment to be high.

b. after 2-5h, closing the first valve 13, opening the second valve 17, opening the first cleaning door 11, cleaning waste silk and dust in the third chamber 9, closing the first cleaning door 11,
c. after 2-5h, opening the first valve 13, closing the second valve 17, opening the second cleaning door 15, cleaning the waste silk and dust in the fourth chamber 10, and closing the second cleaning door 15
And d, taking the step b and the step c as a cycle, and continuously circulating to realize the non-stop cleaning of the waste silk and the dust by the air draft device.
The vibration damper 25 is a rubber block, and the vibration damper 25 is used for reducing the vibration of the fan 6 from being transmitted to the box body 1, so that the noise is reduced; the silencing material is silencing cotton, is laid on the inner wall of the box body 1, the third partition plate 18, the fourth partition plate 21 and the blades of the silencing shutter 26 and is used for reducing noise; one end of the gravity sealing plate 32 is provided with a cover plate capable of covering the corresponding waste wire inlet, the other end of the gravity sealing plate is provided with a balancing weight, the cover plate and the balancing weight are respectively positioned at two sides of a hinge point of the gravity sealing plate 32, and the gravity sealing plate is used for enabling the first cleaning door 11 and the second cleaning door 15 to be easily opened and playing roles in sound insulation and noise reduction; the noise-damping louver 26 is used for dissipating heat from the fan 6 and maintaining the air pressure in the eighth chamber 23 in equilibrium.
The working principle is as follows: when the first valve 13 is opened and the second valve 17 is closed, the fan 6 works to generate air flow, waste silk and dust generated by the hosiery machine sequentially pass through the air suction pipeline, the air pipe, the first waste silk inlet 31 and the third chamber 9 and pass through the first filter screen 12 under the action of the air flow, the waste silk and the dust are retained in the third chamber 9 under the action of the first filter screen 12, and the air flow passes through the first valve 13, the fifth chamber 19, the hose 27, the fan 6, the through hole 24 and the seventh chamber 22 in sequence after passing through the first filter screen 12 and then is discharged from the air outlet 5. In the process, because the second valve 17 is in the closed state, the waste silk and dust can not enter the fourth chamber 10, and the waste silk and dust enter the third chamber 9, namely, the third chamber 9 is in the waste silk recovery state, and the fourth chamber 10 is in the idle state. Under the effect of balancing weight, gravity sealing plate 32 covers second waste silk entry 14, makes fourth cavity 10 not influenced by the air current, prevents that the negative pressure that the air current flow produced from transmitting to fourth cavity 10 in, but the comparatively light second clearance door 15 of opening of workman clears up the waste silk in the fourth cavity 10. When workers clean the fourth chamber 10, the second waste wire inlet 14 is blocked by the gravity sealing plate 32, the waste wire and dust are recovered in a closed environment, air flow sound cannot be directly transmitted to a workshop, and noise can be reduced. In some cases, the sealing effect of the gravity sealing plate 32 may be poor, so that the negative pressure generated by the flow of the airflow is still transmitted into the fourth chamber 10, and the second cleaning door 15 is difficult to open, at this time, the fresh air valve 29 on the fourth chamber 10 is opened to eliminate the negative pressure, and the fresh air valve 29 is closed after the second cleaning door 15 is opened.
Similarly, when the first valve 13 is closed and the second valve 17 is opened, the worker can clean the third chamber 9.
The invention is used for the production of the hosiery machine and has the advantages of no reduction of the production efficiency of the hosiery machine, low energy efficiency, low noise and low maintenance frequency.
