Description

[0002] Dye intermediates, also known as intermediates, refer to various aromatic hydrocarbon derivatives used in the production of dyes and organic pigments. They are made from aromatic hydrocarbons such as benzene, toluene, naphthalene and anthracene from coal chemical industry and petrochemical industry through a series of organic synthesis unit processes (see reaction process). With the development of the chemical industry, the application scope of dye intermediates has expanded to the pharmaceutical industry, pesticide industry, as well as auxiliary agents, surfactants, synthetic fibers and other production departments. There are many varieties of dye intermediates.

The dye intermediates are generally gathered into a pile, and it is difficult to effectively cool the dye intermediates gathered inside. As a result, the cooling time is long, which greatly increases the preparation time of the dye intermediates.

[0021] like Figure 2-3 As shown: the lifting cylinder 11 is connected from top to bottom, and a ring groove 2 is provided in the middle of the circumferential ring wall, a transverse notch 3 is provided at the bottom of the ring groove 2 and passes through the inside of the lifting cylinder 11, a soft board 4 (which can be made of a thin deformable sheet metal material) is inserted at the ring groove 2, and the bottom of the soft board 4 is passed to the transverse notch 3. The lifting assembly includes a vertically arranged support rod 5, a support column 6 is arranged transversely on the top of the support rod 5, and a cylinder 1 7 and a cylinder 2 8 are connected at the bottom of the support column 6, respectively, wherein the cylinder 1 7 is connected to the top of the lifting cylinder 11, and the output end of the cylinder 2 8 is connected to the top of the soft board 4 through an extension rod.

[0022] An isolation seat 9 is provided around the inner wall of the cooling cylinder seat 1. The interior of the isolation seat 9 is hollow. A heat dissipation fan 10 is provided on the top of the cooling cylinder seat 1. The air outlet 12 of the heat dissipation fan 10 faces the inner wall of the cooling cylinder seat 1 and corresponds to the top of the isolation seat 9. Fine holes are provided around the middle and lower part of the isolation seat 9 to allow cold air to penetrate into the interior to contact and dissipate heat for the intermediate. At the same time, the surface of the isolation seat 9 also has a continuously low temperature to allow the intermediate to be fully dissipated.

[0023] A receiving seat 13 is formed in the middle of the heat dissipation fan 10, and a hole array is arranged on the surface thereof to perform air exchange circulation for rapid cooling.

[0024] The method of using the lifting cylinder 11 is as follows: the dye intermediate is placed inside the lifting cylinder 11, and the lifting cylinder 11 and the soft board 4 are lifted upward by the cylinder 1 7 and the cylinder 2 8, wherein the rising speed of the cylinder 2 8 is greater than the rising speed of the cylinder 1 7, so that during the rising process of the lifting cylinder 11, the soft board 4 is gradually retracted into the annular groove 2, and then the dye intermediate is continuously and slowly scattered downward, and the contact heat dissipation is achieved with the cold wind, and the contact area is larger. After the lifting cylinder 11 falls back, it can be inserted into the dye intermediate again (only the circumferential inner wall is inserted, and the resistance is small), and the soft board 4 is moved out and pushed into the lifting cylinder 11 by the downward movement of the cylinder 2 8 to gather the dye intermediate for the next lifting, so as to achieve cyclic scattering and cooling.
