[0002] Dyeing and printing auxiliaries refer to chemicals used in the textile dyeing and printing process to improve the dyeing and printing performance of textile materials, enhance processing efficiency, improve the quality of finished products, or endow textiles with special functions. The reaction vessel is the core reaction equipment in the production of chemical products. For dyeing and printing auxiliaries, it provides a controllable environment (temperature, pressure, stirring rate, etc.) in which various raw materials undergo stirring, heating, cooling, dispersion and other processes to achieve chemical reaction or physical mixing, and finally form qualified auxiliary products.
[0003] In existing dyeing and printing auxiliary reaction vessels, solid raw materials are directly poured into the vessel body through the feed inlet (manhole). During this process, the powdered raw materials generate dust inside the vessel body, which floats upward and adheres to the top or side wall of the vessel body, and does not participate in the subsequent reaction. Based on this, in order to avoid this situation, a dyeing and printing auxiliary reaction vessel is provided. Utility Model Content

[0015] Please see Figures 1-3 In this embodiment of the present invention, a dyeing and printing auxiliary reaction vessel includes a reaction vessel assembly 1 consisting of a vessel body 101 and a connecting cylinder 104. The connecting cylinder 104 is fixed to the top middle of the vessel body 101 and communicates with the inner cavity of the vessel body 101. An L-shaped feed port 105 is also fixed on one side of the top of the vessel body 101. The L-shaped feed port 105 extends into the interior of the vessel body 101. A mixing assembly 2 is installed inside the vessel body 101, the top of the connecting cylinder 104, and the L-shaped feed port 105. The mixing assembly 2 includes a stirring unit, a powder feeding unit, and a dust prevention unit. The stirring unit is used to stir the raw materials inside the vessel 101; The powder feeding unit is used to assist in feeding powdered dyeing and printing auxiliaries. The dust prevention unit uses the liquid material inside the vessel 101 to prevent dust from being generated by the powder material falling into the vessel 101. The stirring unit includes a dual-output shaft gearbox 201, a first rotating shaft 202, and stirring blades 203; A dual-output shaft gearbox 201 is installed on the top of the connecting cylinder 104. A first rotating shaft 202 is fixed to one output end of the dual-output shaft gearbox 201, and passes through the connecting cylinder 104 and extends into the interior of the vessel body 101. A stirring blade 203 is installed at the bottom of the connecting cylinder 104. The stirring blades 203 are driven to rotate by the dual-output shaft gearbox 201 to achieve the raw material stirring operation. The powder feeding unit includes a second rotating shaft 205 and a second spiral blade 206; The second rotating shaft 205 is fixed to the other conveying end of the dual output shaft gearbox 201 and extends from the top of the L-shaped feed port 105 to the interior of the vertical part of the L-shaped feed port 105; The second spiral blade 206 is distributed on the inner side of the vertical part of the L-shaped feed inlet 105 and fixed on the outer side of the second rotating shaft 205; The second spiral blade 206 is driven to rotate by the dual output shaft gearbox 201, which is used to convey the powdered raw material poured into the L-shaped feed port 105 downward to the inside of the reactor body 101. The dust prevention unit includes a first spiral blade 204, an infusion cylinder 207, a connecting column 208, an infusion pipe 209, an annular material box 210, and an annular discharge port 211; The infusion cylinder 207 is distributed inside the vessel body 101 and sleeved on the outside of the first rotating shaft 202. The top of the infusion cylinder 207 is welded and fixed to the top of the inner wall of the vessel body 101 through the connecting column 208. The first spiral blade 204 is distributed inside the infusion cylinder 207 and extends downward to the bottom of the infusion cylinder 207; The annular feed box 210 is distributed inside the vessel body 101 and fixed to the outside of the vertical part of the L-shaped feed inlet 105. The annular discharge port 211 is opened at the bottom of the annular feed box 210. The two ends of the drain pipe 209 are respectively connected to the top side of the delivery cylinder 207 and the top side of the annular feed box 210, and the drain pipe 209 is connected to the delivery cylinder 207 and the inner cavity of the annular feed box 210. The first spiral blade 204 is driven to rotate by the dual output shaft gearbox 201 to draw the liquid material in the vessel 101 upward and form a water curtain through the drain pipe 209, the annular material box 210 and the annular discharge port 211, thereby realizing the separation of the powder discharge area. The top of the vessel body 101 is also fixed with a manhole 102 and multiple flange connection ports 103, and the multiple flange connection ports 103 and the manhole 102 are distributed in a fan shape. The bottom of the vessel body 101 is fixed with a discharge port 106 that communicates with the inner cavity of the vessel body 101.
[0016] In this embodiment, it should be noted that: multiple flange connection ports 103 are used to install temperature sensors, liquid level sensors, and to connect liquid raw material feed pipes and water inlet pipes for dyeing and printing auxiliaries, etc.; in addition, a drive motor connected to the input shaft is installed on the top of the dual output shaft gearbox 201. The operating principle of this dyeing and printing auxiliary agent reaction vessel is as follows: The liquid raw materials of dyeing and printing auxiliaries and water are transported into the reactor body 101 through their respective flange connection ports 103 in a specific ratio. During this process, the drive motor is started, and the drive motor drives the first rotating shaft 202 and the second rotating shaft 205 to rotate synchronously and in the same direction through the transmission of the dual output shaft gearbox 201. The first rotating shaft 202 drives the stirring blades 203 to stir and mix the liquid raw materials of dyeing and printing auxiliaries and water. Afterwards, the printing and dyeing auxiliary powder is poured in through the L-shaped feed port 105 as needed. During this process, the second rotating shaft 205 drives the second spiral blade 206 to rotate, which can convey the powdered raw material falling into the L-shaped feed port 105 downwards, and finally fall into the reactor body 101 from the bottom port of the vertical part of the L-shaped feed port 105. (It should be noted that the liquid level inside the reactor body 101 is lower than the horizontal height of the bottom of the vertical part of the L-shaped feed port 105. The liquid level sensor can monitor the liquid level and control the liquid level accordingly.) At the same time, the first rotating shaft 202 drives the first spiral blade 204 to rotate, which can transport the mixture upward along the inner wall of the delivery cylinder 207 and transport it to the inside of the annular material box 210 through the discharge pipe 209, and then drop it through the annular discharge port 211. In this way, an annular water curtain can be formed on the outside of the vertical part of the L-shaped feed port 105, which can impact the dust generated during the downward fall of the powder, effectively avoiding the problem of dust floating upward and remaining on the top of the reactor body 101. In addition, the mixing efficiency of the mixture can be further improved by circulating the mixture along the pipeline consisting of the infusion cylinder 207, the drain pipe 209, and the annular feed box 210.
[0017] Please refer to this carefully. Figures 1-3 The spiral directions of the first spiral blade 204 and the second spiral blade 206 are opposite, and the distribution diameter of the annular discharge port 211 is larger than the outer diameter of the vertical part of the L-shaped feed port 105.
[0018] In this embodiment: by using the structure that the first spiral blade 204 and the second spiral blade 206 have opposite spiral directions, when the first spiral blade 204 and the second spiral blade 206 rotate synchronously in the same direction, the effect of conveying in opposite directions can be achieved; By using a structure where the diameter of the annular discharge port 211 is larger than the outer diameter of the vertical part of the L-shaped feed port 105, the annular water curtain can be prevented from contacting the outer wall of the L-shaped feed port 105, thus ensuring the integrity of the annular water curtain's shape.
[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
