Problems solved by technology

[0003] The purpose of the present invention is to address the deficiencies of the prior art and provide an independent cooling system for impregnation. After the inside of the impregnation tank is maintained at the rated pressure by introducing inert gas, the inert gas is driven to circulate by the airflow generator, combined with the cooling mechanism. The inert gas is uniformly circulated and cooled to realize the close combination of asphalt and the product while avoiding asphalt leakage, which solves the technical problem of low quality of the impregnated parts in the output process of the impregnated parts in the prior art.

Embodiment 1

[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0029] like figure 1 , 2 Shown in and 3, a kind of impregnation uses independent cooling system, comprises impregnation tank 1, also comprises:

[0030] A drainage mechanism 2, the drainage mechanism 2 includes a drainage assembly A21 and a drainage assembly B22 communicating with the inside of the dipping tank 1, and the hot gas in the dipping tank 1 is transported through the drainage assembly A21 to The airflow generator 23 in the drainage assembly B22, the said drainage assembly B22 is communicated with the interior of the ...

Embodiment 2

[0036] like image 3 and 4 As shown, the parts that are the same as or corresponding to those in Embodiment 1 adopt the reference numerals corresponding to Embodiment 1. For the sake of simplicity, only the differences between Embodiment 1 and Embodiment 1 are described below; the differences between Embodiment 2 and Embodiment 1 The difference is that: the heat conduction component 31 includes a cooling tube 311 sleeved on the drainage component B22, a connecting portion 312 provided on the cooling tube 311, connecting the cooling tube 311 and the refrigeration component 32, and a connecting portion 312 provided on the cooling tube 311 and the refrigeration component 32. The cooling medium 313 between the cooling pipe 311 and the drainage assembly B22; in this embodiment, the refrigeration assembly 32 is a compressor.

[0037] Among them, such as image 3 and 5 As shown, the connection part 312 includes a connection pipe A3121 and a connection pipe B3122 respectively arran...

Embodiment 3

[0041] like figure 1 , 6 and 7, wherein the same or corresponding parts as in the second embodiment adopt the corresponding reference numerals with the second embodiment, for the sake of simplicity, only the difference between the second embodiment and the second embodiment is described below; the third embodiment and the second embodiment The difference is that: it also includes an impurity removal mechanism 4, the impurity removal mechanism 4 is arranged on the drainage assembly B22, the hot air in the dipping tank 1 is cooled by the cooling mechanism 3, and then in the hot air. The tar gas in the airflow flows along the inner wall of the drainage assembly A21 into the impurity removal mechanism 4 during the ascent process; The exhaust gas mixture formed by oil and gas, and when the exhaust gas mixture is cooled by the cooling mechanism 3, it passes through the impurity removal mechanism 4. During the rising process, due to the oil and gas density (2.35kg / m 3 ) is greater ...

Abstract

The invention relates to the technical field of production of artificial graphite and in particular relates to an independent cooling system for impregnation. The independent cooling system comprisesan impregnation tank, a drainage mechanism and a cooling mechanism, wherein the drainage mechanism comprises a drainage assembly A, a drainage assembly B and a gas flow generator; the drainage assembly B is communicated with the inner part of the impregnation tank; the cooling mechanism comprises a heat-conducting assembly which is arranged on the drainage assembly B and is used for carrying out hot gas flow cooling treatment in the drainage assembly B in a heat transmission manner, and a refrigeration assembly which is arranged on the heat-conducting assembly and is used for carrying out cooling treatment on the heat-conducting assembly; after inert gas is introduced and the inner part of the impregnation tank keeps rated pressure, a gas flow generator drives the inert gas to cyclically flow; the cooling mechanism is combined and is used for carrying out uniform and cyclic cooling on the inert gas, so that asphalt and a product are tightly combined, and the asphalt is prevented from leaking out at the same time; the technical problem in the prior art that the quality of an impregnation part is low, caused by the fact that the asphalt leaks out in an output process of the impregnation part, is solved.

Description

technical field [0001] The invention relates to the technical field of artificial graphite production, in particular to an independent cooling system for impregnation. Background technique [0002] At present, graphite production enterprises mainly use heat in and heat out in the impregnation process. The heat out mentioned here refers to pulling the impregnated product out of the impregnation tank above the softening point of the asphalt in the high temperature state. The asphalt has not cooled to the softening point during the output of the impregnated product at high temperature, but under the pressure impregnation system, once the furnace shutdown pressure is relieved, a large amount of asphalt will seep back to the product surface and form on the product surface. A layer of 3-5mm thick solid bitumen. As a result, the bitumen bonded to the surface of the product cannot be recycled, and the impregnation uniformity and depth of the bitumen will be affected.
