Problems solved by technology

However, the color fastness of nylon, silk, wool and blended textiles dyed with acid dyes is generally poor, and it is difficult to meet the requirements of customers and exports. Acid color fixing agents must be used to improve color fastness, so factories use acid color fixing agents in large quantities
[0003] At present, in the production and processing of acidic color fixing agents, the mixing rate of acidic curing agents between raw materials is slow during production, and corner deposits are prone to residues during mixing, and temperature detection in the reactor is prone to deviations
Especially in the existing reactors for the production of acidic curing agents, the raw materials produced by the acidic curing agent are usually added to the reactor. Due to the uneven particle size of the raw materials, the directly added large particles coagulate and settle to the bottom of the reactor , cannot be fully dissolved into the reaction, resulting in a decrease in the quality of the acidic color fixing agent, and cannot make the acidic color fixing agent achieve a good effect of improving color fastness

Embodiment 1

[0027] see Figure 1 ~ Figure 3 , a reaction kettle for producing an acid color fixing agent, comprising a reactor body 1, a reactor material guide cover 7, a filter screen 12, an upper edge cover 13 and a feed tank 19, the top of the reactor body 1 is connected to the reactor guide The material cover 7 and the upper end of the reactor material guide cover 7 are internally connected with a material guide ring 8. The material guide ring 8 is in a ring structure and is provided with a number of guide material through holes on its side, which is convenient for feeding liquid or material from the top of the material guide ring 8. The opening part or the guide through hole of the side wall of the guide ring 8 enters the inside of the reactor body 1; 1 is connected internally, and gaskets 11 are laid in the reaction kettle material guide cover 7 above the return hole 10, and a number of through holes are arranged on the gasket 11 at equal intervals along the circumference, so that t...

Embodiment 2

[0035] The reaction kettle for producing acidic color fixing agent as described in embodiment 1 comprises a reactor body 1, a reactor material guide cover 7, a filter screen 12, an upper edge cover 13 and a feed tank 19, and the top of the reactor body 1 is Connect the reactor material guide cover 7, the upper end of the reactor material guide cover 7 is connected with an upper edge cover 13, and a filter screen 12 is fixed between the reactor material guide cover 7 and the upper edge cover 13, and the upper edge cover 13 The top is connected to the feeding tank 19, the inside of the feeding tank 19 is connected to the inside of the reaction kettle body 1, the top of the feeding tank 19 is equipped with a servo motor 22, and the motor shaft of the servo motor 22 is connected to the rotating shaft 18 through a coupling, The rotating shaft 18 is arranged in the reactor body 1 after passing through the shaft through hole 16 in the middle part of the filter screen 12, and the rotat...

Abstract

The invention discloses a reaction kettle for producing an acid color fixing agent, and belongs to the technical field of acid color fixing agent production equipment. The reaction kettle comprises areaction kettle body and a feeding tank, the top of the reaction kettle body is connected with a reaction kettle material guide cover, the upper end of the reaction kettle material guide cover is connected with an upper edge cover, and the top of the upper edge cover is connected with the feeding tank; the reaction kettle body and the feeding tank are communicated with each other; and are assembled under the threaded connection of the reaction kettle material guide cover and the upper edge cover, so the reaction kettle is convenient and fast to install and good in sealing performance; raw materials for producing the acid color fixing agent can be effectively premixed and smashed in the feeding tank and enter the reaction kettle body for reaction after being filtered by a filter screen, sothe situation that large-particle raw materials are directly added into the reaction kettle body, and the reaction efficiency and effect are affected is avoided; and moreover, under the driving of thesame rotating shaft, crushing blades crush the raw materials in the feeding tank, and the stirring blades perform a mixing reaction on the raw materials in the reaction kettle body, so that the production efficiency of the acid color fixing agent is improved.

Description

technical field [0001] The invention relates to the technical field of acid color fixing agent production equipment, in particular to a reaction kettle for acid color fixing agent production. Background technique [0002] In recent years, with the improvement of people's economic level, the demand for textiles is increasing, and the requirements for textiles are also getting higher and higher, such as requiring more colorful clothing and textile production to meet various standards. With the rapid development of China's textile dyeing and finishing industry. In textile printing and dyeing, a large number of nylon, silk, wool and blended textiles are dyed with acid dyes. Nylon, silk, wool and blended textiles dyed with acid dyes have the advantages of excellent leveling performance, complete color spectrum, and convenient use. They have developed rapidly in recent years and their usage is increasing. However, the color fastness of nylon, silk, wool and blended textiles dyed...
