Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing technology, specifically to a double-barrel mixing device for an overflow dyeing vat. Background Technology
[0002] An overflow dyeing vat is an intermittent dyeing device widely used in the textile printing and dyeing industry. It is mainly used for dyeing fabrics (especially knitted fabrics, towels, elastic fabrics, etc.). During dyeing, dyes and auxiliaries are mixed and then fed into the overflow dyeing vat. As the dyeing process progresses, the amount of dye and auxiliaries gradually decreases, so it is necessary to intermittently replenish the overflow dyeing vat with dyes and auxiliaries.
[0003] The usual practice is to prepare a temporary storage tank, mix the dye and auxiliaries together in the temporary storage tank, and pump it into the overflow dyeing tank when it is necessary to replenish it. However, this method of pre-mixing the dye and auxiliaries can cause the dye and auxiliaries to react and coagulate over a long period of time, which will affect the use. Utility Model Content
[0004] To address the shortcomings of the existing technology, this utility model proposes a double-barrel mixing device for overflow dyeing vat.
[0005] To achieve the above-mentioned technical effects, the present invention adopts the following solution:
[0006] A dual-barrel mixing device for an overflow dyeing vat includes a dye barrel, an auxiliary agent barrel, a dye delivery pipe, an auxiliary agent delivery pipe, a first metering pump, a second metering pump, and a mixing delivery pipe. One end of each of the dye delivery pipe and the auxiliary agent delivery pipe extends into the dye barrel and the auxiliary agent barrel, respectively. The other end of each of the dye delivery pipe and the auxiliary agent delivery pipe is connected to the mixing delivery pipe via a T-junction. The first metering pump is connected to the dye delivery pipe, and the second metering pump is connected to the auxiliary agent delivery pipe. A filter screen is provided at the upper end of the dye barrel, and waste discharge pipes are connected to the lower ends of both the dye barrel and the auxiliary agent barrel. Valves are provided on the waste discharge pipes.
[0007] In a preferred embodiment, the filter screen is detachably mounted on the upper end of the dye barrel, and the edge of the filter screen is provided with a hanging edge for hanging on the upper end of the dye barrel, and the filter screen is located inside the dye barrel.
[0008] In a preferred embodiment, both the dye tank and the auxiliary agent tank are connected to a gas mixing mechanism. The gas mixing mechanism includes a porous gas outlet pipe near the bottom of the dye tank and the auxiliary agent tank. The porous gas outlet pipe has multiple air holes and is connected to a blower located outside the dye tank and the auxiliary agent tank via an air inlet pipe.
[0009] In a preferred embodiment, the dye barrel and the auxiliary agent barrel are mounted on a support frame, the support frame has a base and several legs at the lower end of the base, and the upper end of the base has a limiting groove that matches the dye barrel and the auxiliary agent barrel respectively, and the dye barrel and the auxiliary agent barrel are respectively locked in a limiting groove.

[0011] In a preferred embodiment, the heating element is arranged in a spiral shape.
[0012] Compared with existing technologies, the beneficial effects are:
[0013] This invention has a simple structure and is easy to use. By setting up dye tanks and auxiliary agent tanks to temporarily store dyes and auxiliary agents respectively, when replenishment is needed, the first metering pump and the second metering pump respectively draw out the dyes and auxiliary agents and send them into the mixing and conveying pipe and inject them into the overflow dyeing tank.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] A dual-barrel mixing device for an overflow dyeing vat includes a dye barrel 1, an auxiliary agent barrel 2, a dye delivery pipe 3, an auxiliary agent delivery pipe 4, a first metering pump 6, a second metering pump 7, and a mixing delivery pipe 5. One end of each of the dye delivery pipe 3 and the auxiliary agent delivery pipe 4 extends into the dye barrel 1 and the auxiliary agent barrel 2, respectively. The other end of each of the dye delivery pipe 3 and the auxiliary agent delivery pipe 4 is connected to the mixing delivery pipe 5 via a T-junction. The first metering pump 6 is connected to the dye delivery pipe 3, and the second metering pump 7 is connected to the auxiliary agent delivery pipe 4. A filter screen 8 is provided at the upper end of the dye barrel 1, and a waste discharge pipe 17 is connected to the lower end of both the dye barrel 1 and the auxiliary agent barrel 2. A valve is provided on the waste discharge pipe 17.
[0021] By setting up dye tank 1 and auxiliary agent tank 2 to temporarily store dye and auxiliary agents respectively, when it is necessary to replenish the overflow dyeing tank, the first metering pump 6 and the second metering pump 7 respectively draw dye and auxiliary agents and send them into the mixing and conveying pipe 5, which is then injected into the overflow dyeing tank. The first metering pump 6 and the second metering pump 7 can precisely control the amount of dye and auxiliary agents drawn, thus ensuring that dye and auxiliary agents are drawn according to a certain ratio. This method avoids pre-mixing of dye and auxiliary agents, thereby preventing agglomeration.
[0022] In addition, a filter screen 8 is installed at the top of the dye tank 1. When the dye is poured into the dye tank 1, it can be filtered through the filter screen 8 to remove large undissolved particles and residues in the dye.
[0023] Waste discharge pipe 17 can discharge wastewater when cleaning dye tank 1 and auxiliary agent tank 2, and discharge residual fuel and auxiliary agents after dyeing is completed.
[0024] In a preferred embodiment, the filter screen 8 is detachably mounted on the upper end of the dye tank 1, and the edge of the filter screen 8 is provided with a hanging edge 9 that hangs on the upper end of the dye tank 1. The filter screen 8 is located inside the dye tank 1.
[0025] To facilitate direct removal of the filter screen 8 for cleaning, it is even better to have a handle on the filter screen 8.
[0026] In a preferred embodiment, both the dye tank 1 and the auxiliary agent tank 2 are connected to a gas mixing mechanism. The gas mixing mechanism includes a porous gas outlet pipe 15 near the bottom of the dye tank 1 and the auxiliary agent tank 2. The porous gas outlet pipe 15 has multiple air holes 16. The porous gas outlet pipe 15 is connected to a blower located outside the dye tank 1 and the auxiliary agent tank 2 through an air inlet pipe 12.
[0027] The blower arches through the air inlet pipe 12 to the multi-hole air outlet pipe 15, so that the gas is sent into the dye and auxiliaries through multiple air holes 16. The gas is used as a power source to drive the liquid flow and mixing, and to prevent the dye and auxiliaries from settling and precipitating.
[0028] In a preferred embodiment, the dye barrel 1 and the auxiliary agent barrel 2 are mounted on a support frame, the support frame base 13 and a plurality of legs 14 are located at the lower end of the base 13, and the upper end of the base 13 is provided with limiting grooves 18 that respectively match the dye barrel 1 and the auxiliary agent barrel 2, and the dye barrel 1 and the auxiliary agent barrel 2 are respectively locked in a limiting groove 18.
[0029] In a preferred embodiment, an electric heating tube 19 is embedded in the bottom of the limiting groove 18 corresponding to the dye barrel 1, and the bottom of the dye barrel 1 is made of a material with good thermal conductivity; a digital display temperature sensor 11 is installed on the upper end of the dye barrel 1 through a bracket 10, and the detection end of the digital display temperature sensor 11 extends into the dye barrel 1.
[0030] The dye tank 1 is heated by the electric heating tube 19, so that the dye is kept at a certain temperature. Since the overflow dyeing tank requires high temperature, it can avoid the temperature inside the overflow dyeing tank from dropping too low when adding dye and auxiliaries.
[0031] In a preferred embodiment, the heating element 19 is arranged in a spiral shape.
