[0002] The existing heat treatment method of carbon products is usually to use high-temperature calcination in a roasting kiln to complete high-temperature carbonization of the blank. High-temperature calcination in a roasting kiln uses coal or a sand and gravel mixture as a medium to bury the carbon product blank in it, continuously burn and heat it to make its temperature reach more than one thousand degrees Celsius, and maintain it for a certain period of time, then place it to cool, and finally plan the carbon product out of the roasting kiln to complete the heat treatment process of the carbon product.

[0003] In the long-term production process, it was found that the process of using roasting kilns for heat treatment of carbon products production is not only troublesome, time-consuming and labor-intensive, but also fuel-consuming, which is the main reason for the high production cost. The calcination process has low utilization rate of thermal energy and serious pollution, which can no longer meet the production needs of modern green and environmentally friendly processes. Finally, the heat treatment temperature cannot be accurately controlled during the entire calcination process, and the operation is entirely based on experience. Large-scale systematic standard operations cannot be achieved, resulting in long production cycles and low quality control. Summary of the invention

[0004] The purpose of the present invention is to solve the problems of complex heat treatment process, high energy consumption and high pollution, long production cycle and poor calcination quality of traditional carbon products, and to provide a continuous heat treatment device for carbon products which uses electric heating to control the calcination temperature.

[0025] The cover 12 is hingedly mounted on the heat preservation box 1 , a lock buckle 121 is provided on the open side, and a lock groove 112 is provided at a portion of the heat preservation box 1 corresponding to the lock buckle 121 .

[0026] The insulated box 1 is made of high temperature resistant heat insulating material and needs to be able to withstand a temperature above 1500°C.

[0027] The roaster 2 is in a cylindrical structure, wherein the heating plate groove 22 is in an expanded structure that is larger at the top and smaller at the bottom.

[0028] The heating plate slot 22 is made of a high temperature resistant heat conductive material.

[0029] The heating rings 23 on the heating plate groove 22 of the roaster 2 are evenly arranged with 1-10 circles.

[0030] The heating plate groove 22 is provided with a temperature sensor 221 , and is data-connected to the temperature monitoring controller 3 .

[0031] The connection plug 24 of the roaster 2 and the connection socket 111 of the roasting chamber 11 are arranged in a trapezoidal structure to match each other, so that they can automatically focus and quickly complete the installation and connection during installation.

[0032] Example 2

[0033] Combined with Figure 1-5 As shown, the working principle and process of the continuous heat treatment device for carbon products of the present invention described in Example 1 are as follows:

[0034] The first step: lay a layer of quartz sand in the heating plate groove 22 of the roaster 2, load the carbon product blank 5 into the heating plate groove 22, cover the blank 5 with quartz sand, and make the quartz sand completely cover the blank 5, thereby completing the layout of the blank 5 in the roaster 2.

[0035] Step 2: Open the cover 12 of the insulation box 1, and load the roaster 2 with the blanks 5 arranged into the roasting chamber 11 of the insulation box 1 one by one, insert the connecting plug 24 of the roaster 2 into the connecting jack 111 of the roasting chamber 11, so that the roaster 2 and the temperature monitoring controller 3 complete the circuit connection, close the cover 12 of the insulation box 1, and install the lock buckle 121 of the cover 12 into the lock groove 112 of the insulation box 1 to close the roasting chamber 11.

[0036] Step 3: operate and set the temperature monitoring controller 3, and control the heating power of the heating ring 23 on the roaster 2 by adjusting the low temperature heating button 32, the medium temperature heating button 33 and the high temperature heating button 34, so as to control the temperature of the heating plate groove 22, and finally achieve the purpose of controlling and adjusting the temperature of the quartz sand in the heating plate groove 22, and perform continuous calcination heat treatment on the blank 5 in the roaster 2. The specific control process is as follows:

[0037] (1) First stage heating: Control the heating temperature to about 250° C. After the display 31 shows that the monitored temperature is stable, set the continuous heating time to 4 hours through the time adjustment button 35;

[0038] (2) Second stage heating: Control the heating temperature to about 400° C. After the display 31 shows that the monitored temperature is stable, set the continuous heating time to 4 hours through the time adjustment button 35;

[0039] (3) Third stage heating: Control the heating temperature to about 750° C. After the display 31 shows that the monitored temperature is stable, set the continuous heating time to 8 hours through the time adjustment button 35;

[0040] (4) Fourth stage heating: control the heating temperature to about 1000° C., wait until the display 31 shows that the monitored temperature is stable, and set the continuous heating time to 10 hours through the time adjustment button 35;

[0041] (5) Fifth stage cooling: turn off the low temperature heating button 32, the medium temperature heating button 33 and the high temperature heating button 34, stop the heating operation of the heating ring 23, and wait for the roaster 2 to cool naturally. Under the heat-collecting and heat-insulating effect of the heat-insulating box 1, the heating plate slot 22 cools slowly until the temperature drops to the outdoor temperature. The entire natural cooling cycle exceeds 60 hours.

[0042] Step 4: Open the cover 12 of the heat preservation box 1, use the clamping tool to take out the roaster 2 from the roasting chamber 11 in turn, plan the calcined carbon product out of the quartz sand in the heating plate groove 22, clean the dust on the surface of the carbon product, and the heat treatment operation is completed.

[0043] In the above process steps, the heat dissipation during the heating process can be minimized by the heat-resistant shell 21 of the heat preservation box 1 and the roaster 2, thereby reducing heat loss and achieving the technical effect of energy saving; during the entire calcination process, the calcination temperature can be accurately controlled through staged continuous calcination, thereby ensuring the calcination effect, so the heat treatment time can be accurately controlled, which not only ensures the quality of the product after heat treatment, but also saves heat treatment time and shortens the production cycle.
