Problems solved by technology

[0002] The traditional method of making carbon / graphite felt cylinders is to use manual winding. First, a layer of graphite paper is wrapped on the inner mold of the cylinder, and then carbon cloth is pasted on the graphite paper with an adhesive, and finally wrapped on the carbon cloth. Soft carbon felt, and finally stick a layer of carbon cloth and a layer of graphite paper in sequence, that is, the layers are wrapped by manual adhesive method, and the uneven force of manual wrapping will easily lead to poor adhesion between layers Tight, easy to produce delamination and cracking during use, and the thermal insulation performance is adversely affected, and this process generally requires 5-6 people to operate at the same time, the production operation time is too long, the production efficiency is low, and the labor cost is high

Embodiment 1

[0031] as attached figure 1 The shown automatic molding equipment for making hard carbon / graphite felt cylinders includes an impregnation device 1 connected to an extrusion device 2 , and the extrusion device 2 is connected to a winding device 3 .

[0032] The dipping device 1 includes a dipping tank 5 filled with an adhesive 4 , the bottom of the dipping tank 5 is provided with a stirring device 6 , the bottom of the dipping device 1 is connected to a wire filter 11 , and the wire filter 11 is located above the stirring device 6 . The purpose of stirring device 6 is to ensure that the graphite powder in the binder 4 does not precipitate during the process of immersing the soft carbon felt 12 into the binder 4 in the dipping tank 5, so that the sticky substance immersed in the soft carbon felt 12 The graphite powder of the mixture 4 has a stable composition ratio, so that the adhesive properties of the adhesive 4 can be fully exerted.

[0033] The extrusion device 2 includes ...

Embodiment 2

[0036] Utilize the automatic forming equipment described in embodiment 1 to make the working process of hard carbon / graphite felt cylinder material be:

[0037] The first step: Wrap a layer of sulfuric acid paper on the inner mold 9 of the cylinder, attach graphite paper, and then use an adhesive to attach a layer of carbon cloth to the surface of the graphite paper;

[0038] Step 2: Turn on the automatic forming equipment for the hard carbon / graphite felt tube material, select the target tube material diameter as 380 mm, and adjust the rotation speed of the motor 8 to 3 min / turn.

[0039] The third step: first dip the soft carbon felt 12 into the adhesive 4 in the dipping tank 5, and then extrude the excess adhesive 4 through the reverse rotation extrusion process of the upper and lower wheels of the extrusion wheel 7, Flow back into the dipping tank 5 through the deflector 10, and the extruded soft carbon felt 12 is evenly and tightly wound on the inner membrane 9 of the tub...

Embodiment 3

[0051] The basic process of the present embodiment and embodiment 2 is identical, and different parameters and steps are as follows:

[0052] 1. Step 2: Turn on the automatic forming equipment for the hard carbon / graphite felt tube material, select the target tube material diameter as 600mm, and adjust the rotation speed of the motor 8 to 5 min / turn.

[0053] 2. The fifth step: after the high-temperature carbonization heat treatment shown in Table 8, the hard graphite felt tube material is obtained.

Abstract

Automatic molding equipment and method for producing hard carbon / graphite felt tube material belong to the field of carbon / graphite felt preparation. The automatic molding equipment comprises an impregnating device connected with an extruding device, and the extruding device is connected to a winding device. The impregnating device comprises a dipping tank containing a binder; the bottom of the dipping tank is provided with an agitator; the extruding device comprises at least one group of extruding wheels in upper and lower structural arrangement; and the winding device comprises a motor connected to inner mold of a tube material. The invention adopts the automatic mode for producing the hard carbon / graphite felt tube material, which has, the closer bonding between layers, no layering, high precision, high strength and low ash content compared with a traditional hand-wrapped composite carbon / graphite felt material, so as to improve the insulation performance and prolong life. An automated production mode only needs 2-3 operator for feeding materials in an initial stage and monitoring in the production process, saves 70% of the operating time, greatly improves production efficiency, and reduces labor and material costs.
