Problems solved by technology

[0002] Diethyltoluenediamine is mainly used as a curing agent for waterproof coatings, and diethyltoluenediamine has strong corrosiveness and can cause severe burns. When the existing diethyltoluenediamine is produced, the raw materials need to be prepared according to a certain The ratio of the two valves is strictly matched, and the flow volume of the raw materials at the same time is usually changed by opening the valve. However, this method cannot accurately compare the opening sizes of the two valves. At the same time, the pressure in the lower part of the tank is different, which will also lead to two The flow rate of the two materials is different, and the artificial proportioning leads to inaccurate proportioning and large errors, resulting in poor production quality of diethyltoluenediamine
[0003] At the same time, in the production process of diethyltoluenediamine, a large amount of impurities will be attached to the reactor and the agitator. If the impurities cannot be cleaned up in time, the impurity layer on the reactor and the agitator will gradually become thicker, which will cause serious damage to the subsequent cleaning. Difficult and will affect the quality of diethyltoluenediamine at the same time

Embodiment 1

[0032] A diethyltoluenediamine production device with the function of accurate material proportioning, such as Figure 1-Figure 10 As shown, it includes a first support frame 1, and the first support frame 1 is bolted with a mixing chamber 2, the mixing chamber 2 gradually changes from a circle to a square from bottom to top, and a discharge pipe is embedded in the bottom of the mixing chamber 2. And a valve is installed on the discharge pipe of the mixing chamber 2, a top plate 3 is bolted on the upper side of the mixing chamber 2, and an intake valve 301 is embedded in the right part of the top plate 3, and the intake valve 301 enters the air to make diethyltoluene diethyl ether. The amine is quickly discharged from the mixing chamber 2 to reduce the discharge time. The left part of the top plate 3 is embedded with a water inlet pipe 4, and the right port of the water inlet pipe 4 is equipped with a nozzle for multi-angle water spraying. The nozzle on the right end of the wat...

Embodiment 2

[0035] On the basis of Example 1, as Figure 3-Figure 6 As shown, the quantitative proportioning mechanism includes a second support frame 601, the second support frame 601 is bolted to the rear side of the mixing chamber 2, the upper side of the second support frame 601 is bolted with a support column 602, and the upper part of the support column 602 There are two material boxes 603 connected by bolts, and feeding pipes are embedded in the upper parts of the two material boxes 603. The liquid raw material is pumped into the two material boxes 603, so that the two material boxes 603 are always filled with liquid raw materials. The first water distribution pipes 604 communicate with each other, the lower ends of the two first water distribution pipes 604 are welded with a plurality of cylindrical shells 605, and a first solenoid valve 606 is respectively installed between the plurality of cylindrical shells 605 and the adjacent first water distribution pipes 604, The upper par...

Embodiment 3

[0045] On the basis of Example 2, as Figure 11 and Figure 12 As shown, it also includes a filter mechanism, which is used to clean the impurities in diethyltoluenediamine. The filter mechanism includes a filter shell 901, which is slidably connected to the lower part of the rotating shell 701. The shape is truncated cone, and the filter shell 901 is set in a truncated cone shape for discharging the impurities on the upper part of the mixing chamber 2, so that the impurities on the upper side of the filter shell 901 converge to the middle, and the left and right sides of the sealing plate 705 are respectively slidably connected with sliding rods 902 , a seal is installed between the two sliding rods 902 and the sealing plate 705, the upper ends of the two sliding rods 902 are respectively welded with circular plates for limiting, and the outer sides of the two sliding rods 902 are respectively sleeved with a second spring 903 , the two ends of the two second springs 903 are ...

Abstract

The invention aims to provide a diethyltoluenediamine production device with an accurate material proportioning function, and relates to the field of diethyltoluenediamine production devices.The diethyltoluenediamine production device comprises a first supporting frame, a mixing cabin is fixedly connected to the first supporting frame, a quantitative proportioning mechanism is arranged on the first supporting frame, the quantitative proportioning mechanism communicates with the mixing cabin, and the mixing cabin communicates with the quantitative proportioning mechanism; a stirring mechanism is arranged in the mixing cabin, and an inner wall cleaning mechanism is arranged in the mixing cabin. The quantitative proportioning mechanism is arranged, so that the influence of the bottom pressure of the material box on feeding is avoided, and meanwhile, the situation that the production quality of a diethyl toluenediamine product is reduced due to inaccurate proportioning of two liquid materials caused by different feeding amounts of the two liquid materials is avoided; the stirring mechanism is arranged, so that the stirring time of two liquid materials is shortened, and the production efficiency of diethyltoluenediamine is improved; the inner wall cleaning mechanism is arranged, so that the influence of impurities on the inner wall of the mixing cabin on the next preparation of the diethyltoluenediamine is avoided, and the quality of the diethyltoluenediamine is improved.

Description

technical field [0001] The invention relates to the field of diethyltoluenediamine production devices, in particular to a diethyltoluenediamine production device with the function of accurate material proportioning. Background technique [0002] Diethyltoluenediamine is mainly used as a curing agent for waterproof coatings, and diethyltoluenediamine has strong corrosiveness and can cause serious burns. During the production of existing diethyltoluenediamine, it is necessary to use raw materials according to certain The proportion of the two valves is strictly matched, and the flow volume of the raw materials at the same time is usually changed by the size of the open valve. However, this method cannot accurately compare the opening sizes of the two valves, and the pressure at the lower part of the tank is different, which will also lead to two The flow rates of the various materials are different, and the artificial proportioning leads to inaccurate proportioning and there i...
