Description

Technical Field

[0001] The utility model relates to the technical field of disperse dye production equipment, in particular to a device for continuous diazo reaction of thiazole disperse dyes. Background Art

[0002] Disperse dyes containing multiple heteroatoms are mainly thiazoles, which contain nitrogen, sulfur and other heteroatoms in the molecules. Introducing such heterocycles into dye molecules can often improve certain properties, such as increasing the brightness of the dye, and have good light resistance and reddening effect. The difference between the two dyeing methods (high temperature and high pressure and hot melt dyeing) is small, and the fastness to light, sublimation, soaping and other aspects is good. The quality is stable and is valued. In the synthesis of thiazole disperse dyes, diazonium salts usually participate in the reaction as key intermediates. Through continuous operation, the reaction conditions can be precisely controlled.

[0003] In the existing diazo continuous reaction production device, when the material undergoes diazo reaction, due to the high viscosity of the material itself, the material is not only easy to adhere to the inner wall of the production device, but also the fluidity of the material is low, which makes the mixing efficiency of the two materials low, affecting subsequent production. Utility Model Content

The screw extends into the cavity of the tank body, the screw and the movable seat are threadedly connected, the spoiler ring is located in the cavity of the tank body, and the spoiler ring and the movable seat are fixedly connected. Through the design of the spoiler ring that can move back and forth up and down, the material produces turbulence during the mixing reaction process, and can drive the material to flow up and down, thereby improving the efficiency of the diazo continuous reaction.

[0009] In order to solve the problem of low stability of the spoiler ring during the up and down movement, the spoiler unit further includes a slide rod and a sliding seat matching the slide rod. The slide rod is located in the cavity of the tank body, the end of the slide rod is fixedly connected to the tank body, the axis of the slide rod is parallel to the axis of the screw rod, the sliding seat is slidably connected to the slide rod, and the sliding seat is fixedly connected to the spoiler ring.

[0010] In order to solve the problem that the material is easily adhered to the inner wall of the tank body, scrapers are further installed on the upper and lower end surfaces of the sliding seat.

[0011] In order to solve the problem of low turbulence generation efficiency of the spoiler ring, the spoiler ring is further provided with spoiler holes for fluid to pass through at intervals along its circumference.

[0012] In order to solve the problem of low turbulence generation efficiency of the spoiler ring, the spoiler ring further includes a plurality of spoiler protrusions formed at intervals on the inner wall surface, and the spoiler protrusions and spoiler holes are arranged in a staggered manner.

[0013] The invention further comprises a turbulent ring surrounding a stirring shaft of the stirring unit.

[0022] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0023] like Figure 1 The utility model is a schematic diagram of the structure of a device for continuous diazo reaction of thiazole disperse dyes, comprising a tank body 1, a stirring unit 2 and a flow disturbance unit 3.

[0024] The tank body 1 has a cavity, which is used to contain materials and provide a reaction space for the materials;

[0025] The stirring unit 2 is installed on the tank body 1. The stirring unit 2 is used to provide power for mixing the materials in the tank body 1. The stirring unit 2 includes a stirring motor, a stirring shaft, and a stirring paddle installed on the stirring shaft. The stirring paddle is located in the tank body 1. The output end of the stirring motor is connected to the input end of the stirring shaft by transmission.

[0026] like Figure 2 As shown, the spoiler unit 3 is used to cause turbulence in the material. The spoiler unit 3 includes a spoiler drive 31, a screw rod 32, a movable seat 33 matched with the screw rod 32, and a spoiler ring 34. The spoiler drive 31 is located outside the tank body 1, and the spoiler drive 31 and the tank body 1 are fixedly connected. The spoiler drive 31 is a motor. The output end of the spoiler drive 31 and the input end of the screw rod 32 are transmission connected. The spoiler drive 31 is used to provide power for the rotation of the screw rod 32. The screw rod 32 extends into the cavity of the tank body 1, and the screw rod 32 and the movable seat 33 are threadedly connected. The spoiler ring 34 is located in the cavity of the tank body 1, and the spoiler ring 34 and the movable seat 33 are fixedly connected. Through the design of the spoiler ring 34 that can move back and forth up and down, the material generates turbulence during the mixing reaction, and can drive the material to flow up and down, thereby improving the efficiency of the diazo continuous reaction, that is, the up and down reciprocating movement of the spoiler ring 34 itself can generate the first turbulence.

[0027] like Figure 2 , Figure 3 As shown, the spoiler ring 34 is provided with spoiler holes 341 for fluid to pass through at intervals along its circumference, the spoiler holes 341 can generate a second turbulent flow, and the material passing through the spoiler holes 341 undergoes a process of first contraction and then diffusion, thereby further enhancing the mixing of the materials, and the inner wall surface of the spoiler ring 34 is provided with a number of flow-interrupting protrusions 342 at intervals, the spoiler protrusions 342 and the spoiler holes 341 are arranged alternately, and the spoiler protrusions 342 can generate a third turbulent flow.

[0028] The spoiler ring 34 surrounds the stirring shaft of the stirring unit 2. The spoiler ring 34 is arranged obliquely in the tank body 1. It can generate a fourth turbulent flow, further increase the turbulence, and have a certain degree of obstruction in the height direction, thereby changing the flow direction of the material and preventing the flow of the material around the spoiler ring 34 during the up and down movement of the spoiler ring 34.

[0029] The spoiler unit 3 also includes a slide rod 35 and a sliding seat 36 matching the slide rod 35. The slide rod 35 is located in the cavity of the tank body 1. The end of the slide rod 35 is fixedly connected to the tank body 1. The axis of the slide rod 35 is parallel to the axis of the screw rod 32. The sliding seat 36 is slidably connected to the slide rod 35. The sliding seat 36 is fixedly connected to the spoiler ring 34. Through the cooperation of the slide rod 35 and the sliding seat 36, the stability of the movement of the spoiler ring 34 can be increased.

[0030] like Figure 2 As shown, scrapers 37 are installed on the upper and lower end surfaces of the sliding seat 36, and scrapers 37 are installed on the upper and lower end surfaces of the movable seat 33. The scrapers 37 can extend the inner wall of the tank body 1 to scrape off the material adhering to the inner wall. The scrapers 37 can be semi-annular, and the two scrapers 37 on the same side are spliced ​​to form an annular structure, so as to scrape the material.

[0031] When in use, the material enters from the feed port on the top surface of the tank body 1, the stirring unit 2 starts to mix the material, and in this process, the material undergoes a continuous diazo reaction, the spoiler driving member 31 starts to drive the screw 32 to rotate, driving the spoiler ring 34 to move downward, and the rotation direction of the spoiler driving member 31 changes to drive the spoiler ring 34 to move upward. In the process of the spoiler ring 34 moving up and down reciprocatingly, the material generates turbulence, thereby increasing its mixing efficiency, thereby improving its continuous diazo reaction efficiency.
