Description

Environment-friendly energy-saving loose wool dyeing and dewatering integrated machine
Technical Field
The invention relates to the field of textile printing and dyeing equipment, in particular to an environment-friendly energy-saving type loose wool dyeing and dewatering integrated machine.
Background
The traditional loose fiber dyeing process flow is as follows: bulk fiber enters a pot → pretreatment (drainage) → dyeing (drainage) → post-treatment (drainage) → dehydration (plug-in dehydration) → drying → finished product packaging. From the whole process, the water washing after the pre-treatment boiling-off (or boiling bleaching), the neutralization, the soap boiling, the hot water washing and the cold water washing are needed after the dyeing, the whole process flow needs a plurality of water washing processes, and a large amount of water needs to be consumed after water is fed and drained for a plurality of times. Before each washing, water can be drained before water is drained, but because of the high water absorption of the cotton fibers, a large amount of sewage is contained in the drained fibers and among the fibers, and in the subsequent washing process, the sewage can prevent impurities (stains washed down in the pretreatment process and loose colors in the dyeing process) among the fibers from diffusing outwards, so that the washing efficiency is greatly reduced. Most of the existing loose fiber dyeing machines adopt a circulating pump to carry out dyeing and water washing by utilizing circulating injection of dyeing liquid, the existing dyeing machines do not have a self-dewatering function due to the limitation of a mechanical structure, loose fibers are taken into other equipment for dewatering during dewatering, and the conventional method is to transfer the fibers into a loose fiber centrifugal dewatering machine for centrifugal dewatering. The process consumes a great deal of time and energy and has high labor intensity. Therefore, the environment-friendly and energy-saving type loose wool dyeing and dewatering integrated machine is invented under the environment-friendly and high-pressure background of the current printing and dyeing industry, and is in the forefront.

The technical scheme for realizing the invention is as follows: an environment-friendly energy-saving type loose wool dyeing and dewatering integrated machine comprises a base, wherein a dye liquor circulating pump and a main cylinder body are arranged on the base, the main cylinder body is fixed on the base through a supporting and connecting system, a dewatering motor is connected below the main cylinder body, and a loose wool cylinder cage and a dye liquor heating system are arranged in the main cylinder body; the main cylinder body is also provided with a feeding system, and the top end of the main cylinder body is provided with a dye liquor nozzle.
The dye liquor circulating pump is connected with the bottom end of the main cylinder body through a dye liquor circulating pipeline, a hose is further connected to the dye liquor circulating pipeline, and the other end of the hose is connected with a dye liquor nozzle at the top end of the main cylinder body.
The loose wool net cage is arranged on the net cage base, the net cage base is fixed on the mandrel, an output shaft of the dehydration motor is connected with a driving wheel, and the driving wheel is connected with a driven wheel connected with the mandrel.
And a dye liquor spraying pipe is arranged in the loose wool net cage, and the upper end of the dye liquor spraying pipe is connected with a dye liquor nozzle.
And a pressing plate is arranged on the fluffy net cage.
And a spring damper is arranged on the support connecting system.
The dye liquor heating system is composed of a heating coil and is arranged in the main cylinder body.
The invention has the beneficial effects that: the invention optimizes the loose fiber dyeing process, greatly shortens the total process time of the process, greatly improves the efficiency and saves a large amount of water resources. The optimized process flow is as follows: bulk fiber enters a pot → pretreatment (self-dehydration) → dyeing (self-dehydration) → post-treatment (self-dehydration) → drying → packaging of the finished product. This loose fiber dyeing dehydration all-in-one has reduced a large amount of washing times, and this all-in-one can be before each washing, and the centrifugation is dehydrated earlier, then washes. Centrifugal dewatering can remove most of non-combined water on the surface of fibre and between fibres. Compared with the water washing process with water inlet and drainage circulation after centrifugal dehydration, the water washing process saves time and water resources on the one hand, and has high efficiency. Dyeing dehydration all-in-one passes through a large amount of sewage of centrifugal dehydration discharge, and the pressure of washing that can significantly reduce forms certain negative pressure between the fibre in the dye vat after the dehydration simultaneously, and rivers permeate more easily during the washing, are favorable to the washing, the decontamination, the edulcoration to reduce the track number of washing, the water conservation reaches 30% -40%, has promoted the efficiency of washing. The technological process that the fibers need to be transferred to the centrifugal dehydrator after dyeing and washing is reduced, the technological operation of dyeing, dewatering and washing can be completed in the integrated machine, the technological process is simplified, a large amount of water resources and human resources are saved, the capital investment of equipment is reduced, the loose fiber dyeing process is optimized, and the method has revolutionary significance in the printing and dyeing industry.
The loose wool dyeing and dewatering integrated machine can optimize water circulation, improve efficiency, reduce waste of water resources, save water and energy, and reduce the number of washing; the loose wool dyeing and dewatering integrated machine has better stability and balance when treating loose fibers of more than 150 kg. The perfect combination of the dyeing equipment and the dewatering equipment into an integrated machine can shorten the process flow, reduce the labor intensity, reduce the equipment investment, reduce the environmental protection pressure, realize low investment and high productivity and maximize the benefit.
