Description

Technical Field

[0002] Ammonium thioglycolate is a chemical used to straighten hair. It is a colorless or light red liquid with a special smell. It turns purple-red when it comes into contact with iron. It is hygroscopic and easily oxidized. It is used as a reagent for the determination of iron and in the pharmaceutical industry. In cosmetics, it is used as a curling agent and nutrient solution to play a styling role. It is mainly produced by the neutralization method, using thioglycolic acid and ammonium bicarbonate as raw materials, undergoing a neutralization reaction, and then filtered to obtain it.

[0003] In the process of using the existing neutralization device for ammonium thioglycolate production, the addition of raw materials is usually controlled manually according to the pH value of the reactants in the neutralization device, and the pH value of the reactants needs to be monitored multiple times during the mixing process, resulting in the need to repeatedly add the raw materials. In addition, the raw materials will agglomerate during storage, resulting in the blocking of the conveying pipe when entering the neutralization device or the phenomenon that the dissolution process is long, which is relatively time-consuming. Therefore, an ammonium thioglycolate mixed feeding structure is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the embodiment, Figure 1-7 A mixed feeding structure of ammonium thioglycolate is provided. The utility model comprises a jacketed reaction tank 1, a motor 2 is fixedly installed on the top of the jacketed reaction tank 1, a rotating shaft 3 located inside the jacketed reaction tank 1 is fixedly connected to the bottom of the output shaft of the motor 2, a stirring rod 4 is fixedly installed on the outside of the rotating shaft 3, a water pump 5 is fixedly installed on the top of the jacketed reaction tank 1, the right side of the water pump 5 is connected to the inside of the jacketed reaction tank 1 through a pipeline, a feeding box 6 is fixedly installed on the top of the jacketed reaction tank 1, a storage box 7 is slidably installed inside the feeding box 6, and a bottom of the feeding box 6 is fixedly installed. A weighing scale 8 is installed, and a telescopic rod 9 is fixedly installed on the top of the weighing scale 8, and the top of the telescopic end is fixedly connected to the bottom of the storage box 7. A feeding pipe 10 extending to the inside of the storage box 7 is fixedly installed on the top of the feeding box 6. An inclined filter plate 11 is fixedly installed inside the storage box 7. A discharge pipe 12 penetrating through and extending to the inside of the jacketed reaction tank 1 is fixedly installed on the bottom of the storage box 7. A recovery box 13 is fixedly connected to the rear side of the feeding box 6. The filter plate 11 penetrates and extends to the inside of the recovery box 13. A through hole 15 is opened between the feeding box 6 and the recovery box 13.

[0028] As a preferred embodiment of the present invention, the left side of the water pump 5 is connected to the inside of the external thioglycolic acid storage tank through a pipeline, and the feeding pipe 10 is connected to the discharge point of the external conveying auger.

[0029] Under the action of the water pump 5, thioglycolic acid is pumped into the jacketed reaction tank 1 to facilitate alignment for addition, and the speed at which ammonium bicarbonate enters the storage box 7 can be controlled by the auger when conveying ammonium bicarbonate, thereby facilitating the filter plate 11 to filter the ammonium bicarbonate.

[0030] As a preference of this embodiment, an exhaust pipe 16 communicating with the interior of the jacketed reaction tank 1 is fixedly installed on the top of the jacketed reaction tank 1 .

[0031] In the process of neutralization of thioglycolic acid and ammonium bicarbonate, G8-2 neutralized waste gas (VOCs, ammonia) will be produced, which is convenient for subsequent discharge.

[0032] As a preference of this embodiment, a liquid level sensor 17 is fixedly mounted on the top of the inner wall of the jacketed reaction tank 1 , and a temperature detector 18 located in front of the liquid level sensor 17 is fixedly mounted on the top of the inner wall of the jacketed reaction tank 1 .

[0033] The liquid position inside the jacketed reaction tank 1 can be detected by the liquid level sensor 17 to determine whether it is necessary to continue to inject thioglycolic acid. Heat will be generated during the neutralization process. The temperature inside the jacketed reaction tank 1 is detected by the temperature detector 18, so that cooling water is introduced into the jacket to facilitate alignment and cooling.

[0034] As a preferred embodiment of the present invention, a support plate 19 is fixedly installed on the outer side of the jacketed reaction tank 1, a cylinder 20 is fixedly installed on the top of the support plate 19, a connecting plate 21 is fixedly connected to the top of the telescopic end of the cylinder 20, a moving rod 22 is fixedly installed on the bottom of the connecting plate 21, and a pH detector 23 located inside the jacketed reaction tank 1 is fixedly connected to the bottom of the moving rod 22.

[0035] When it is necessary to detect the pH value of the reactants inside the jacketed reaction tank 1, it is only necessary to make the top of the telescopic end of the cylinder 20 act on the bottom of the connecting plate 21, so as to facilitate the control of the movement of the moving rod 22, so that the pH value detector 23 can better detect the pH value of the reactants and prevent the pH value detector 23 from being in the reactants for a long time and causing corrosion damage.

[0036] As a preferred embodiment of this embodiment, a vibration motor 24 is fixedly installed on the right side of the feeding box 6.

[0037] When filtering the ammonium bicarbonate, the filtering efficiency of the filter plate 11 is enhanced by the vibration motor 24, and the agglomerated ammonium bicarbonate can quickly enter the recovery box 13 for recycling.

[0038] Working principle:

[0039] First, thioglycolic acid is pumped into the interior of the jacketed reaction tank 1 by the water pump 5, and the position of the thioglycolic acid in the jacketed reaction tank 1 is detected by the liquid level sensor 17, so as to control the start and stop of the water pump 5. When adding ammonium bicarbonate, the ammonium bicarbonate is filtered by the filter plate 11, so that the agglomerated ammonium bicarbonate passes through the inclined filter plate 11 and enters the interior of the recovery box 13, and the weight of the raw material is detected by the weighing scale 8, which is convenient for subsequent discharge. When the pH value needs to be detected, the connecting plate 21 and the moving rod 22 are driven by the telescopic end of the cylinder 20 to move up and down, so as to complete the pH value detection of the reactant, and at the same time avoid corrosion caused by being inside the reactant for a long time.
