Problems solved by technology

The disadvantage of this heating method is that when the heat exchanger is heated by steam, condensed water with a higher temperature is discharged, which wastes a certain amount of energy; , and the temperature of the discharged cooling water is also high, and as the temperature of the dye liquor decreases, the temperature of the discharged cooling water also gradually decreases. The high temperature cooling water and the low temperature cooling water are discharged in the same water pipe, wasting a certain amount of water. energy

Embodiment 1

[0022] Embodiment 1: As shown in Figure 1, the present invention comprises dyeing cloth vat 1, is provided with water level pipe 2 in the dyeing cloth vat 1, and its upper side is then provided with cloth inlet and outlet 3, and dyeing cloth vat 1 passes through The pipes are respectively connected with the filter 4 and the dye liquor supply and drainage valve 5, and the other end of the filter 4 is connected with the feeding barrel 6 and the circulating water pump 7 through the pipes, and there is a passing flange between the dyeing cloth cylinder 1 and the circulating water pump 7 10 into one water cooling exchanger 8 and oil heating exchanger 9.

[0023] As shown in Figure 5, the water cooling exchanger 8 and the oil heating exchanger 9 have the same structure, and both include a cylinder 16, which is provided with layered heating tubes 11, and the heating tubes 11 can be metal round tubes or heat transfer coefficients. It is made of high special-shaped metal pipe, and the ...

Embodiment 2

[0029] Embodiment 2: The basic structure of this embodiment is the same as that of Embodiment 1, except that a water cooling exchanger 8 and an oil heating exchanger 9 connected in series are connected between the dyeing cloth cylinder body 1 and the circulating water pump 7, as shown in the figure 2. As shown in Figure 6. Its working process is with embodiment 1.

Embodiment 3

[0030]Embodiment 3: The basic structure of this embodiment is the same as that of Embodiment 1, except that the outlet 14 provided on the cylinder 16 of the water cooling exchanger 8 can be divided into a main outlet 14a and a secondary outlet 14b, wherein the main outlet 14a Located above the cylinder 16, the auxiliary outlet 14b is located below the cylinder 16, and the diameter of the auxiliary outlet 14b is smaller than that of the main outlet 14a. The main outlet 14a is connected with a pipe 22 , the auxiliary outlet 14b is connected with a pipe 21 , and the other end of the pipe 21 communicates with the pipe 22 . As shown in Figure 3 and Figure 5. The working process of this embodiment is the same as that of Embodiment 1, the difference is that when the cooling water is discharged, it can flow out from the main outlet 14a with a large flow rate, and flow out from the auxiliary outlet 14b with a small flow rate, and then divert to the diversion device after being aggregat...

Abstract

The invention discloses a oil-heat thermal recovery dyeing machine, which comprises: a dyeing cylinder body connected with a filtrator that links to a circulating water pump, linking a water-cool exchanger with a shunt device and oil-heat exchangeer integrated by flange or in series between said cylinder body and pump. This invention can make good use of hot water, and increases utility for heat energy.

Description

technical field [0001] The invention discloses an oil heating and heat recovery type dyeing machine, which belongs to the technical field of textile printing and dyeing equipment. Background technique [0002] A dyeing machine is a machine that dyes and pre-treats textiles. Its basic principle is to use heated dye liquor to dye and pre- and post-treatment textiles. At present, two heating methods, direct heating and indirect heating, are generally used for heating the dye liquor. Direct heating is to put high-temperature and high-pressure steam directly into the dyeing machine to reach the temperature required for the dyeing liquid. Its advantage is that the heating method is simple, and its disadvantage is that after the steam heats the dyeing liquid, condensed water will be generated and mixed with the dyeing liquid, changing the temperature of the dyeing liquid. The ratio of the dye solution may affect the quality of dyeing. Indirect heating uses steam to pass through ...
