Description

Technical Field

[0001] This utility model relates to the field of reaction device technology, specifically to a raw material reaction device for copper di-n-butyldithiocarbamate. Background Technology

[0002] In the field of fine chemical production, the efficiency and purity of the synthesis reaction of copper di-n-butyldithiocarbamate are directly related to the quality stability of downstream products. Especially in applications such as rubber vulcanization accelerators and metal passivators, improper control of reaction conditions may lead to excessive impurities in the product, affecting the final use effect.

[0003] Traditional reaction equipment commonly used in workshops relies mainly on stirred tanks for raw material mixing and reaction. Temperature is controlled by simple heating or cooling jackets, which can basically meet the basic synthesis requirements.

[0004] However, in actual production, such devices always encounter thorny problems: the raw material vapors such as carbon disulfide that volatilize during the reaction process are easy to escape directly. At first, this only causes raw material loss and increases production costs. Over time, these toxic gases not only pollute the operating environment but also corrode equipment parts. At the same time, the single stirring structure often leads to uneven mixing of raw materials, excessive or insufficient local reaction, which further reduces the purity of the product.

[0005] To solve these problems, some manufacturers install simple condensation devices, but then they fall into new predicaments: either the condensation efficiency is low and most of the steam is still directly discharged; or the raw materials recovered by condensation cannot be accurately replenished, and the asynchrony between stirring and temperature control leads to large fluctuations in the reaction system and significant batch differences in the products, which in turn increases the difficulty of subsequent purification.

[0006] This not only leads to waste of raw materials and environmental pressure, but also makes it difficult to guarantee the stability of product quality. In order to solve the above problems, a raw material reaction device for copper di-n-butyl dithiocarbamate is proposed. Utility Model Content

[0023] Please see Figure 1-4 This utility model provides a new technical solution: a raw material reaction device for copper di-n-butyl dithiocarbamate, including two L-shaped support frames 11, which are arranged in a front-to-back manner.

A stirring assembly is arranged on the stirring tank 2. The condensing assembly is mounted on the heat insulation cover 1. The condensing assembly includes a condensing box 8, which is fixedly connected to the right side of the heat insulation cover 1. A partition 15 is fixedly connected inside the condensing box 8, and multiple curved cooling pipes 14 are fixedly connected to the rear surface of the partition 15. Among them, the front ends of multiple curved cooling pipes 14 all penetrate through the front surface of the partition 15, and the ends of multiple curved cooling pipes 14 away from the partition 15 all penetrate through the upper surface of the condenser box 8. Among them, each of the multiple curved cooling pipes 14 is located outside the condenser box 8 and is fixedly connected to a conveying box 6 that communicates with its interior. The upper surface of the conveying box 6 is fixedly connected to a conveying pipe 5 that communicates with its interior.

[0024] Furthermore, two connecting pipes 12 communicating with the interior are fixedly connected to the front side of the upper surface of the condenser box 8, and filter boxes 10 communicating with the interior are fixedly connected to the upper surface of the two connecting pipes 12. Two connecting pipes 12 are used to transport uncondensed carbon disulfide gas into the interior of the filter box 10.

[0025] Furthermore, the filter box 10 is equipped with an activated carbon filter plate inside, and an exhaust pipe is installed on the filter box 10.

[0027] Furthermore, the discharge pipe 9, the cooling medium inlet pipe 7, and the cooling medium outlet pipe 13 are all equipped with switch valves. The upper surface of the mixing tank 2 is fixedly connected to a steam outlet pipe 4 that communicates with its interior, and the conveying pipe 5 is fixedly connected to the steam outlet pipe 4.

[0028] Furthermore, the stirring assembly includes a servo motor 3, the output end of which is fixedly connected to a drive shaft 16, the lower end of which rotates through into the interior of the stirring tank 2, and four stirring plates 18 arranged in a cross shape are fixedly connected to the outer wall of the drive shaft 16.

[0029] Furthermore, multiple sawtooth blocks 19 are fixedly connected to the side of each of the four stirring plates 18 away from the drive shaft 16, and anchor-type stirring plates 17 are fixedly connected to the front and rear surfaces of the outer wall of the drive shaft 16.

[0030] Furthermore, both anchor-type mixing plates 17 are located below the four mixing plates 18.

[0031] Furthermore, a heat transfer component is installed on the upper part of the mixing tank 2. The heat transfer component adopts a composite structure of a half-pipe jacket and an internal spiral coil: the half-pipe jacket is circulated with -5℃ refrigerant to control the first-stage reaction temperature (15-20℃), and the spiral coil is circulated with 30℃ hot water to maintain the second-stage reaction temperature (40-45℃).

[0033] Furthermore, when using the raw material reaction device of copper di-n-butyl dithiocarbamate, the raw material is first put into the interior of the stirring tank 2 through the feed pipe, and then the heat transfer component and servo motor 3 are started. The output of the servo motor 3 drives the drive shaft 16 to rotate, and the drive shaft 16 drives four cross-shaped stirring plates 18 to rotate synchronously. During the rotation, the multiple serrated blocks 19 on the stirring plates 18 can cut and crush the raw materials in the mixing tank 2, increasing the contact area of ​​the raw materials. At the same time, the two anchor-type stirring plates 17 located below rotate with the drive shaft 16, which can fully stir the raw materials at the bottom of the mixing tank 2, preventing the raw materials from settling at the bottom of the tank. Through the overall action of the stirring components, the raw materials can be mixed more evenly and the reaction rate can be accelerated.

During the reaction, the steam generated enters the conveying pipe 5 through the steam outlet pipe 4 on the stirring tank 2, and is then conveyed to the conveying box 6 by the conveying pipe 5. Subsequently, it is dispersed into multiple curved cooling pipes 14. At this time, the cooling medium enters the condensing box 8 through the cooling medium inlet pipe 7. Under the separation of the baffle 15, the cooling medium comes into full contact with the curved cooling pipes 14, condensing and cooling the steam in the pipes. The heated cooling medium is discharged through the cooling medium outlet pipe 13. The condensed liquid substance adheres to the inner wall of the curved cooling pipes 14 and eventually collects at the bottom of the condensing box 8. It can be discharged and collected by opening the switch valve on the discharge pipe 9. Among them, the carbon disulfide gas that is not completely condensed enters the filter box 10 through the two connecting pipes 12 on the condensation box 8. After being adsorbed and purified by the activated carbon filter plate inside the filter box, it is discharged through the exhaust pipe to avoid the direct emission of harmful gases and environmental pollution. Once the raw materials have reacted, the valve on the discharge pipe on the lower surface of the mixing tank 2 can be opened to discharge the reaction products. The device features a stirring assembly to improve raw material mixing efficiency, a heat transfer assembly to precisely control temperature and ensure reaction conditions, and a condensation assembly to achieve steam recovery and exhaust gas purification. These features enable the device to improve reaction efficiency and product purity while reducing pollutant emissions during the reaction of copper di-n-butyldithiocarbamate, thereby enhancing the device's practicality and environmental friendliness.
