Problems solved by technology

[0005] The object of the present invention is to provide a graphite expansion device with fast heating speed and uniform heating, so as to solve the existing graphite expansion proposed in the above-mentioned background technology. In this way, fuel combustion heating will use a large amount of fuel and will produce a large amount of combustion emissions, which is relatively polluting the environment. However, the heating speed of fuel combustion heating and electric heating is relatively slow, which cannot achieve fast and efficient heating of graphite, and the production efficiency is relatively slow. In addition, if the distribution of graphite is not uniform enough when it enters the puffing heating furnace, it will be heated unevenly, so there will be a problem of uneven expansion, which will affect the use effect of expanded graphite; Continuous cooling of graphite is also a problem that needs to be solved

[0029]SeeFigure 1-5, A graphite puffing device with fast heating speed and uniform heating, comprising a cylindrical shell 1, a screw feeder 2 is fixedly installed on the top side of the cylindrical shell 1, and the outer side of the screw feeder 2 A first motor 3 is fixedly installed, and the first motor 3 is drivingly connected to a screw 4 arranged transversely in the screw feeder 2. A hopper 5 is provided at the top and outer end of the screw feeder 2. The bottom inner end of the feeder 2 is provided with a discharging pipe 6 extending into the inside of the cylindrical shell 1, and a second motor 7 is fixedly installed on the other side of the top of the cylindrical shell 1. The output shaft 8 is fixedly sleeved with an eccentric wheel 9 arranged in the cylindrical shell 1, a sieve tray 10 is arranged under the lowering pipe 6, and the bottom of the sieve tray 10 is fixedly installed with a screen 11, so Slide rods 12 are fixedly installed on both sides of the sieve tray 10, an...

Embodiment example 2

[0033]SeeFigure 6 Specifically, the thin-walled guide tube 15 is made of high-temperature resistant ceramic material, and the thickness of the thin-walled guide tube 15 is 3-5 mm; and the top of the thin-walled guide tube 15 is provided with a horn-shaped expansion that is inclined to the outside.口26. The thin-walled guide tube 15 made of high-temperature resistant ceramic material can play a role of heat insulation when the graphite is heated, and it can also prevent the falling graphite from spilling out of the thin-walled guide tube 15, and the insulated thin-walled guide tube 15 is placed in the induction The inside of the hollow copper tube coil 16 will not be heated, and the thinner thickness will not affect the inductive heating effect of the induction hollow copper tube coil 16; and the top of the thin-walled guide tube 15 is provided with a flared opening 26 inclined to the outside. It can prevent the graphite that has fallen from the sun from falling to the outside of the ...

Abstract

The invention discloses a graphite puffing device high in heating speed and uniform in heating. The graphite puffing device comprises a cylindrical shell, a spiral blanking machine is fixedly mountedon one side of the top of the cylindrical shell, a first motor is fixedly mounted on the outer side of the spiral blanking machine, and the first motor is in driving connection with a screw rod transversely arranged in the spiral blanking machine; a hopper is arranged at the outer end of the top of the spiral blanking machine, a discharging pipe extending into the cylindrical shell is arranged atthe inner end of the bottom of the spiral blanking machine, a second motor is fixedly installed on the other side of the top of the cylindrical shell, and an eccentric wheel arranged in the cylindrical shell is fixedly connected to an output shaft of the second motor in a sleeving mode. A sieve tray is arranged below the discharging pipe, a sieve net is fixedly installed at the bottom of the sievetray, sliding rods are fixedly installed on the two sides of the sieve tray, and the sliding rods are installed in sliding rails fixedly installed on the inner wall of the cylindrical shell in a sliding mode. According to the invention, uniform and rapid heating of graphite can be realized, and expanded graphite can be effectively cooled.

Description

Technical field[0001]The invention relates to the technical field of graphite expansion, in particular to a graphite expansion device with fast heating speed and uniform heating.Background technique[0002]The main step in the production of graphite expanded flexible graphite is the process of instantaneously expanding the expandable graphite after chemical treatment into vermicular graphite at high temperature.[0003]Existing graphite expansion generally uses a graphite expansion furnace, and the heating method generally uses fuel combustion heating and electric heating wire heating. Fuel combustion heating will use a large amount of fuel and will produce a large amount of combustion emissions, which will pollute the environment. Both fuel combustion heating and electric heating wire heating methods have slow heating speeds, which cannot achieve rapid and efficient heating of graphite, and the production efficiency is slow; in addition, if the graphite enters the puffing heating furna...
