Description

Built-in dual-purpose heat exchanger for dyeing machine

The invention relates to a dyeing machine, in particular to a double-layer heat exchanger provided in the body thereof, which can be used for elastically selecting a dyeing machine structure of one or two layers of the built-in dual-purpose heat exchanger used at the same time.

According to the general dyeing machine, a storage tank capable of accommodating the dyeing liquid is formed by the body, and a section of the cloth to be dyed is firstly dipped in the interior of the dyeing liquid, and then driven by the cloth wheel and the nozzle to make the cloth For continuous rotation, each piece of cloth can be evenly dipped in the dye solution to achieve the purpose of dyeing the cloth. Furthermore, in order to improve the quality and efficiency of the dyed fabric, the temperature profile of the dye liquor is usually set for the characteristics of the cloth, and the heat exchanger is the main device for providing the temperature change of the dye liquor.

Further, according to the general dyeing machine structure, as shown in FIG. 1, a storage tank 91 for accommodating the dyeing liquid L is formed inside a body 90, and the upper end of the body 90 is provided with an inlet and outlet port 92 and a guide device 93. And the nozzle 94; the dyeing liquid L is pressurized by the pump 95 and sent to the heat exchange device 96, wherein the steam T1 can raise the dye liquid L, and the cooling water T2 can lower the dye liquid L; after heat exchange The dye liquor L is then ejected by the nozzle 94 to push the cloth C back to the storage tank 91 for a cyclic dip operation. Since the heat exchange device 96 is disposed outside the body 90, the cycle of heating and cooling of the dyeing liquid becomes longer, and the cost of the pipe wiring and the dyeing liquid is relatively increased; and the heat exchange device 96 is disposed outside. It will occupy a large space, and its pipeline heat energy will be lost, which will increase the heat exchange time. Therefore, the dyeing machine structure of the external heat exchange device has many hidden defects in terms of resources and energy efficiency.

In recent years, some manufacturers have developed a dyeing machine structure with a built-in heat exchange device, such as the Republic of China patent M334849 "heat exchange device for dyeing machine", in which a group of heat exchange tubes 14 are placed under the inside of the body 100, such as 2, and an inner net 19 is axially spaced apart from the body 100, so that the bottom periphery of the dyeing machine body 100 and the lower portion of the inner net 19 are formed as a heat exchange space 15, and the heat exchange tube member 16 is Placed in the heat exchange space 15, as shown in FIG. However, it is checked that the cloth 17 will retain a lot of fibers and cloth dust in the dyeing liquid 18 in the dyeing space 16, so when the pump 17 pressurizes the dyeing liquid 18, the dyeing liquid 18 will pass through the inner net 19 to enter the heat. The exchange space 15 exchanges heat with the heat exchange tube member 16. However, the fiber and the cloth waste can not block the passage of the dye solution 18 due to the inability to pass through the inner net 19. Therefore, the dye solution 18 is not fully heat exchanged, and the pump 17 is pumped. The circulation of the dye liquor 18 will also be affected by the inability to draw the dye liquor 18. Furthermore, the mechanism is only provided with a set of heat exchange tubes 14 . For manufacturers without steam boilers, only the hot kerosene can be used to heat the dye liquor 18, and when the cooling process needs to be switched to cooling water, the residual hot kerosene will pollute. Cooling water also affects the accuracy of the temperature profile. Therefore, this patent cannot effectively improve the lack of dyeing machines for conventional external heat exchange devices.
