Referring to fig. 1 and 2, a horizontal dyeing kettle for supercritical carbon dioxide comprises a dyeing kettle body 10 having a receiving space, and a dyeing support 20 installed in the receiving space.

The dyeing kettle body 10 is provided with a feed inlet 101, at least three discharge outlets 102 communicated with the containing space, and a collecting pipe 103 communicated with the at least three discharge outlets 102. In this embodiment, the inlet 101 and the outlet 102 are respectively located at two opposite ends of the dyeing kettle body 10.

Specifically, for the discharge ports 102, at least three discharge ports 102 are located in the same plane, and the plane is perpendicular to the flow direction of the supercritical carbon dioxide fluid in the dyeing kettle body 10. Moreover, in the plane, the included angle between any two adjacent discharge ports 102 is the same.

It should be understood that if the dyeing vessel body 10 is provided with three or at least four outlets 102. For example, if the dyeing kettle body 10 is provided with three discharge ports 102, the distribution included angle between two adjacent discharge ports 102 is 120 °; for another example, if the dyeing kettle body 10 is provided with four discharge ports 102, the distribution included angle between two adjacent discharge ports 102 is 90 °.

It should be understood that, between the discharge port 102 and the manifold pipe 103, the dyeing kettle body 10 is further provided with a confluence space 104 communicating the discharge port 102 and the manifold pipe 103, and the confluence space 104 is used for confluence of the carbon dioxide critical fluid flowing out from the plurality of discharge ports 102, so as to finally flow out of the dyeing kettle body 10 through the manifold pipe 103.

A guide channel 201 is formed inside the dyeing support 20, a plurality of guide holes 202 are formed in the side wall of the dyeing support 20, and each guide hole 202 is communicated with the guide channel 201 and the accommodating space. It should be understood that the plurality of diversion holes 202 are not only uniformly distributed in the circumferential direction of the dyeing support 20, but also uniformly distributed in the extending direction of the dyeing support 20.

In the dyeing support 20, the feed inlet 101 is communicated with the inlet of the flow guide channel 201 of the dyeing support 20. Moreover, the position of the dyeing support 20 for winding the cloth belt to be dyed is located between the feed opening 101 and the discharge opening 102.

When in use, a cloth belt to be dyed is wound on the outer side of the dyeing support 20, and the supercritical carbon dioxide fluid with the dye dissolved in the supercritical carbon dioxide fluid enters the flow guide channel 201 of the dyeing support 20 through the feed inlet 101 of the dyeing kettle body 10, enters the accommodating space through the flow guide hole 202, and finally flows out of the accommodating space through the at least three discharge ports 102 and flows out through the collecting pipe 103.

In the process that the supercritical carbon dioxide fluid flows into the accommodating space from the diversion hole 202 of the dyeing bracket 20, the dye dissolved in the supercritical carbon dioxide fluid can be used for dyeing the cloth belt to be dyed;

moreover, since the dyeing kettle body 10 is provided with at least three discharge ports 102 which are communicated with the accommodating space, and the at least three discharge ports 102 are uniformly distributed in the same plane, the supercritical carbon dioxide fluid in the dyeing kettle body 10 can uniformly flow to the corresponding discharge ports 102, and the siphon effect caused by only one discharge port is avoided.

Moreover, the structure of the at least three outlets 102 enables the supercritical carbon dioxide fluid on the plane perpendicular to the extending direction of the dyeing support 20 to be uniformly distributed, so that the cloth belt to be dyed on the plane perpendicular to the extending direction of the dyeing support 20 can be uniformly dyed.

While the foregoing description shows and describes the preferred embodiments of the present invention, it is to be understood that the invention is not limited to the forms disclosed herein, but is not to be construed as excluding other embodiments and is capable of use in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as described herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
