Background technology:
In practice, to spinning room preparation machine with the key request of the trash eliminator on similar devices in ginning operation be: can separate reliably the impurity detecting as far as possible little with the loss amount of fashion fiber.
In this trash eliminator, detected material, i.e. cotton or synthetic fiber, also directed for example, through the detection sensor systems in scanning room, camera system by pneumatic conveying in rectangular channel.Subsequently the impurity being detected is separated to waste chamber by the bar of for example drying.In blowing bar, being furnished with a row can be by sniffer across width and by the valve that blows out of controlling respectively time response.Herein for reliable separation, important parameter is the quantity of actuated valve, required time delay and holds time.
The quantity of actuated valve is determined by the possible cross section flow from sensing point to burble point of material.Determined by the speed of impurity with holding time time delay.In the case, particularly the friction speed of impurity has caused usually having to keep long holding time, and flies over to meet reliably impurity.
But, for reliable separation, to a large amount of actuated valves and long hold time need to also mean high good fiber loss amount, this is owing to there being a large amount of good fibers to occur along with real impurity is transported in waste chamber.
Therefore, in trash eliminator in the prior art, between sniffer and separator, keep as far as possible little spacing, so that the quantity of the valve that will activated, and hold time and corresponding good fiber loss amount minimizes.
Second is reduced the factor of efficiency separator and is, a large amount of valves and long holding time have caused a large amount of air to be transported in waste chamber, and this has caused indoor air pressure to increase, and therefore has air to backflow to feed in passage.This just exists the separated impurity air that backflowed to be again transported to and to feed to the risk in passage.
The trap system with the device of the keeping system of being made up of sheet metal, all pressure passageway or intermittent running is known.The latter's object is that impurity separated and that be positioned at waste chamber is transferred out to waste chamber.For this purpose, for example, trap is opened with from the pneumatic absorption waste material of waste chamber.But for fear of simultaneously from feeding to aspirating more good fibrous material passage in waste chamber, other trap is opened and guides fresh air to be fed in waste chamber.The significant drawback of this scheme is, substantially prevent from being drained with other impurity and entering the pressure conditions change in the periodic process of waste chamber at waste chamber.In order to keep long waste chamber emptying time interval, it is very large that waste chamber is correspondingly done.
Known feasible pattern is that waste chamber is carried out to continuous suction in addition.But, for fear of being also inhaled into waste chamber from feeding to the good fibrous material of passage, must first fresh air be fed to waste chamber and waste disposal air capacity is adjusted to the pressure condition of feeding to passage, due to the pressure condition constantly changing, this is difficult to accomplish in practice, may limit in addition and feed to the air capacity that can have in passage.
Finally, the common trait of said method is, in order to ensure effect, must between sniffer and separator, keep little spacing.
Particularly in equipment because its function or structure and can not in the case of between sniffer and separator, select short spacing or wherein air conditions very difficult, said apparatus cannot become can received solution, select a large amount of valves and long holding time because have in order to actuate impurity, a large amount of so separated impurity by refunds again in passage.
At known device (in EP0989214 A1), separation container has the device of controlling the air of recalling from separation container for temporary transient.For the controlled air that withdraws, under conventional operating condition, it is to be sealed by the trap not returning that the air on separation container withdraws hole.In addition, this air withdraws device and leads to backward channel, and separation container is again connected to fiber transmission channel by this backward channel.Alternatively, backward channel is connected with outlet.In the time that compressed-air atomizer place sends pulse of compressed air, in order to discharge air from separation container, air feeder or syringe are turned round.The latter is connected to compressed-air line by valve.This valve receives the control signal of self-control device, obtains the swabbing action along the direction of arrow by opening valve.Can also use other applicable device, such as fan etc., with withdraw air from separation container; Under individual cases, it may be essential also air being withdrawn to hole controlled the closing of employing.This device is complicated aspect equipment, particularly owing to there being control device.Problem particularly in, aspect control, need in addition according to actual lock out operation.Finally, must accurately control the amount that withdraws air and have a negative impact aspect air balance avoiding, described negative effect meeting brings undesirable operation interrupted.
Summary of the invention:
Therefore, the problem to be solved in the present invention is to provide a kind of equipment as described in this paper beginning, and it has avoided the shortcoming in preceding method, and structurally simple especially, and removing impurities from fabaric mterial flow reliably, and can not have a negative impact to air balance.
By provide a kind of on spinning preparation machine or gin, be used for surveying and defibre material in or between the equipment of impurity can address this problem, this equipment has fiber conveying pipeline, be useful on sensing system and the separator of surveying impurity along this pipeline arranged in succession on direction of transfer, this separator has transverse to the work of fiber conveying pipeline, for at least one compressed-air atomizer of blow air is provided, this fiber conveying pipeline has and opposed the first opening of compressed-air atomizer, this first opening passes into the separation chamber being connected with junk remover, and the blow air from described at least one compressed-air atomizer can be again fed to conveying air stream from separation chamber by other opening in the system of sealing, separation chamber's integrated connection is to fiber conveying pipeline, and blow air will be passed through filter or sieve before turning back to conveying air stream, it is characterized in that, also comprise the induction element that blow air can be imported to separation chamber, be arranged in the described induction element of the separation chamber that is arranged in burble point, described filter or sieve and described junk remover collaborative work, make by the air that blows pulse actuating because vortex impacts the filter or the sieve that connect fiber conveying pipeline, and can again enter fiber conveying pipeline, and by the junk remover that blows fiber that impurity that pulse transports becomes reconciled and be sent to continuous operation, and be removed thus.
Because blow air directly turns back to conveying air stream from separation chamber, just obtain the balance between air capacity and air pressure in simple especially mode.Compared with known device, it does not have the complicated troublesome and control device that must accurately regulate.Because filter, sieve or analog that only can by air, impurity can not pass through be disposed between separation chamber and fiber conveying passage, impurity is separated and has been avoided the pollution to carrying air stream in simple and reliable mode.It is without the amount that regulates waste disposal air.Equipment of the present invention can continuous operation, and therefore can obtain higher impurity separative efficiency with low waste chamber height and large detection and separator spacing.Because separation chamber is connected to fiber conveying passage on the whole, thereby obtain compact structure.Therefore, save space on the one hand, obtained on the other hand the unit of high effect.
