A kind of hopper that is used for cold dyeing batching
Technical field
The utility model relates to a kind of printing and dyeing hopper, refers more particularly to a kind of hopper that is used for cold dyeing batching.
Background technology
Cold rolling batch-dying process (cold dyeing) does not need to resemble the pad-dry-cure dyeing (heat tinting) and the later fabric of dyeing must be dried, and can save baking operation, thereby can save a large amount of energy; Simultaneously, cold dyeing also has the degree of fixation height, pollutes advantages such as few, has obtained using widely at dyeing.But, because the hopper that uses all is original traditional big capacity hopper at present, and the used dye liquor of cold dyeing all is the mixed liquor of REACTIVE DYES and alkaline agent, its chemical property is very unstable, if long just very easy decomposition of holdup time, the Dry Sack rate will reduce greatly in hopper; Simultaneously, fabric holdup time in hopper is long also to be easy to produce phenomenons such as sagging, thereby influences dyeing quality.In addition, present printing and dyeing enterprise is faced with huge environmental protection pressure, and energy cost is constantly soaring, quantity of order is more and more littler, quality requirements is more and more higher, and the time of delivery is also shorter and shorter, makes traditional big capacity hopper can not satisfy this demand of current dyeing.
The utility model content
Technical problem to be solved in the utility model is: the holdup time of the dye liquor that a kind of shortening mixes by REACTIVE DYES and alkaline agent and the hopper of the holdup time of fabric in this dye liquor are provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of hopper of cold dyeing batching, comprise: dye liquor tank, the below of dye liquor tank is provided with cooling bath, and dye liquor tank and cooling bath are isolated fully, and dye liquor tank is provided with charging aperture and overfall, and charging aperture is positioned at the top of overfall, the bottom of dye liquor tank also is provided with discharging channel, and the top of cooling bath is provided with water inlet, and the bottom of cooling bath is provided with drainage gallery; The bottom of described dye liquor tank is semicylindrical cavity, and the radius of semi-cylindrical shaped cavity is 70 to 80 millimeters, and the center of circle of semi-cylindrical shaped cavity to the height of overfall is 55 to 65 millimeters.
Above-mentioned cooling bath is a semi-cylindrical shaped.
The beneficial effects of the utility model are: because shape and radius that the utility model is contained the sap cavity body to the dye liquor tank bottom have been done strict qualification, thereby make the overall control of dye liquor in the dye liquor tank in a reasonable range, the time that dye liquor is detained in dye liquor tank can be very not long, and can not decompose because of the REACTIVE DYES in the dye liquor influences the cold dyeing quality; Simultaneously, the holdup time of fabric in dye liquor is also more suitable, thereby can not produce phenomenons such as sagging because of the fabric material feeding too much.

The specific embodiment
The utility model will be further described below in conjunction with above-mentioned accompanying drawing, but the utility model should not only limit to this embodiment.
As shown in Figure 1 and Figure 2, the hopper of a kind of cold dyeing batching described in the utility model, comprise: dye liquor tank 1, the below of dye liquor tank 1 is provided with cooling bath 4, and dye liquor tank 1 is isolated fully with cooling bath 4, and dye liquor tank 1 is provided with overfall 5 and charging aperture 2, and charging aperture 2 is positioned at the top of overfall 5, bottom at dye liquor tank 1 also is provided with discharging channel 7, and the top of cooling bath 4 is provided with water inlet 6, and the bottom of cooling bath 4 is provided with the passage 41 that discharges water; The bottom of above-mentioned dye liquor tank 1 is semicylindrical cavity, and the radius R of semi-cylindrical shaped cavity is 70 to 80 millimeters, and the center of circle 18 of semi-cylindrical shaped cavity to the height H of overfall 5 is 55 to 65 millimeters.In addition, in order to adapt with dye liquor tank 1, in the actual fabrication, cooling bath 4 is also made semi-cylindrical shaped; During practical application, fabric guide roll 8 can be arranged on 18 positions, the center of circle of semi-cylindrical shaped cavity.
As shown in Figure 3, operation principle of the present utility model is: at first, the discharging channel 7 that will be positioned at dye liquor tank 1 bottom respectively blocks up with the drainage channel 41 that is positioned at cooling bath 4 bottoms, after pouring into cold water in the cooling bath 4, with being housed, the dye liquor pipe of dye liquor and the charging aperture 2 of dye liquor tank 1 connect, and control flow, make the dye liquor liquid level in the dye liquor tank 1 just in time be under the overfall 5 of dye liquor tank 1, in order to avoid cause unnecessary waste, to need the fabric 9 of cold dyeing to enter into dye liquor tank 1 then along advancing cloth rewinder roll 13, under fabric guide roll 8 guiding,, enter among a pair roller 15 through draw-out roller 14.
Because shape, radius and the center of circle 18 to the height of overfall 5 that the utility model is contained the sap cavity body to dye liquor tank 1 bottom has been done strict qualification, make the overall control of dye liquor in the dye liquor tank 1 in a reasonable range, like this, dye liquor in the hopper just need carry out replenishing quickly, the time that dye liquor is detained in dye liquor tank 1 can be very not long, and can not decompose because of the REACTIVE DYES in the dye liquor influences the cold dyeing quality; Simultaneously, the holdup time of fabric 9 in dye liquor is also more suitable, thereby can not produce phenomenons such as sagging because of fabric 9 material feedings too much.
