Description

Technical Field

[0001] The present invention relates to the technical field of pretreatment equipment for fibers, and specifically to a method for improving the operation efficiency of a lint cleaner, a make-up air adjustment device, and a cleaner. Background Art

[0002] At present, for the pneumatic lint cleaners in service on the market, although their model specifications are different, the lint removal method is fixed, and only the parameters for controlling the air flow selected by each are different, because the only criterion for evaluating the quality of this performance design is to use the minimum air volume on the premise of ensuring 100% lint removal.

[0003] For the convenience of description, let the minimum lint removal air volume required for each single machine be Q1. Then, for a production line composed of 6 gin stands, the most ideal designed air volume of the collecting fan is Q = 6Q1, and the air pressure P is responsible for overcoming the pipeline resistance. However, in practice, there will be an air leakage rate in the pipeline, so a supplementary designed air volume Q2 should be added, that is, Q = 6Q1 + Q2.

[0004] In the actual process, there is a complex problem. That is, although the structure of each machine is the same and the structural parameters of its lint pipeline are also the same, due to manufacturing errors and different relative positions with the collecting dust cage, the resistance values at the make-up air inlets of each machine are different. According to the principle of aerodynamics, the smaller the resistance of an air inlet, the larger the air volume entering through that port. And the cross-sectional dimensions of the air inlets are basically the same. A large air volume results in a high wind speed, and the high wind speed in turn increases the air resistance at that place. When the resistances of all 6 air inlets are balanced, make-up air starts to be supplied to all of them. Obviously, the air volumes entering each make-up air inlet are different, that is, Q1 is inconsistent in practice. When the actual make-up air volume of a certain machine is less than Q1, the lint removal rate of this machine will not reach 100%. Therefore, a supplementary designed air volume Q3 should be added, that is, Q = 6Q1 + Q2 + Q3. And this Q3 increases with the increase in the number of make-up air inlets (that is, the number of gin stands in the process), and the increased amount is definitely not linear. Therefore, this Q3 is the energy loss and waste caused by system errors or design defects. In the current cotton processing technology, the value of Q3 is very large. The intention of the present invention is to greatly reduce the value of Q3 to reduce energy waste, or to enable each lint cleaner to achieve a 100% lint removal rate when the air volume of the collecting fan is just sufficient.

[0024] Specifically, the circumferential positioning member 101 is provided with an axially penetrating circumferential locking hole, and a circumferential locking pin 101-1 is threadedly connected in the circumferential locking hole. The circumferential locking pin 101-1 is a flat cone head pin, and an internal flow angle or a cross-shaped tool groove is provided at the tail end of the circumferential locking pin 101-1.

[0029] Embodiment 2:

[0030] Based on Embodiment 1, in this embodiment, the air make-up adjustment device of the lint cleaner is applied to a lint cleaner with air flow cotton removal.

[0031] The lint cleaner with air current cotton stripping includes a box body. A dust chamber is arranged inside the box body, and the dust chamber is communicated with the outside of the box body. A dust cage 301 is arranged inside the dust chamber, and the dust chamber is open below the dust cage 301. A rear cotton pulling roller 302 and a front cotton pulling roller 303 are arranged in the opening of the dust chamber. A licker-in 309 is arranged below the rear cotton pulling roller 303 and the front cotton pulling roller 303. A waste discharging knife 308 is arranged on one side of the licker-in 309. A waste suction pipe 310 is arranged below the waste discharging knife 308 on the box body. A cotton suction channel is arranged on the side of the licker-in 309 away from the waste discharging knife 308 on the box body, and the cotton suction channel is communicated with a cotton collecting air duct 318.

[0032] Specifically, below the rear cotton pulling roller 302 and the front cotton pulling roller 303, a drafting roller 305 and a feed roller 306 are arranged above the licker-in 309.

[0033] Specifically, an upper roller scraper 304 and a lower roller scraper 307 are arranged between the rear cotton pulling roller 303 and the drafting roller 305. The upper roller scraper 304 is arranged tangentially to the rear cotton pulling roller 303, and the lower roller scraper 307 is arranged tangentially to the drafting roller 305.

[0034] Specifically, a licker-in lower cover 311 and a licker-in lower cover three 314 are arranged below the licker-in 309 on the box body. The cotton suction channel includes a cotton suction channel lower cover plate 315 and a cotton suction channel upper cover plate 316. The licker-in lower cover 311 extends to the outer wall of the waste suction pipe 310, and the licker-in lower cover three 314 extends to the cotton suction channel lower cover plate 315. A supplementary air inlet 312 is arranged between the licker-in lower cover 311 and the licker-in lower cover 314. The supplementary air adjustment device 10 described in Embodiment 1 is arranged at the supplementary air inlet 312 on the box body. The supplementary air adjustment plate 102 blocks the supplementary air inlet 312, and the backing plate 105, the circumferential locking pin 101-1 and the axial locking member 104 fix the supplementary air adjustment plate 102. The size of the supplementary air inlet 312 is controlled through the supplementary air adjustment device 10, and the supplementary air volume is controlled.

[0035] Specifically, the cotton suction channel upper cover plate 316 is connected to a licker-in gap adjustment plate 317. The licker-in gap adjustment plate 317 controls the size of the gap between the cotton suction channel upper cover plate 16 and the licker-in 309. The licker-in gap adjustment plate 317 is connected to the cotton suction channel upper cover plate 316 through a stud, an orbital hole and a nut. The licker-in gap adjustment plate 317 closes the gap between the cotton suction channel upper cover plate 16 and the licker-in 309 as much as possible.

[0036] Operation process of a lint cleaner with air current cotton stripping: Under the blowing of the air in the brush cotton air reservoir and the suction of the fan of the lint cleaner, the lint is sent to the surface of the dust cage 301. After the cleaned lint follows the saw-tooth roller 309 and turns past the lower cover 311 of the saw-tooth roller, due to the sharp expansion of the space around the saw-tooth roller 309, the cotton fibers hooked by the saw teeth tend to break away from the saw-tooth roller 309 under the action of air current and centrifugal force. The collecting fan generates sufficient negative pressure in the closed collecting pipeline through the collecting dust cage. Under the action of this negative pressure, as Figure 2 shown, under the sealing action of the lower cover plate 315 of the cotton suction channel, the upper cover plate 316 of the cotton suction channel, and the saw-tooth roller gap adjusting plate 317, the external air current can only flow in through the air supply opening 312, and a directional air current is formed in the channel formed between the lower cover 314 of the saw-tooth roller and the saw-tooth roller 309. And the speed of this directional air current should obviously be higher than the surface linear speed of the saw-tooth roller 309 to ensure that the air current brushes the cotton clean and avoid the saw-tooth roller from rewinding cotton. The air current speed is controlled by the air supply adjustment device 10.

[0037] In Embodiment 2 and Embodiment 3, by adjusting the sizes of the first air supply opening 215 and the air supply opening 312, the air resistance of the air supply opening of each lint cleaner reaches a balanced state, so as to ensure that the cotton stripping air volume of each one is basically the same, reduce the value of Q3 in the background technology, reduce energy waste, and enable each lint cleaner to reach a 100% cotton stripping rate when the air volume of the collecting fan is just sufficient. It should be noted that currently, the lint cleaners in service on the market do not have this functional design.
