[0002] The preparation process of carbon molecular sieve includes a carbonization step, that is, a heating furnace is used to carbonize the semi-finished material of carbon molecular sieve (carbon molecular sieve extruded strips). The structure of the existing heating furnace includes a furnace body, which is provided with a heating device, an exhaust device and a feed door. When in use, the semi-finished material of carbon molecular sieve is put in through the feed door, and the furnace body is heated by the heating device to carbonize the semi-finished material. The carbonized fume is discharged from the exhaust device. After the carbonization is completed, the carbonized material is taken out.

[0003] The existing heating furnace is used by putting semi-finished materials into the furnace and taking out the carbonized materials after heating for a period of time. Frequent shutdowns for taking out and unloading materials consume a lot of time, which not only has low production efficiency, but also cannot achieve continuous production, which is not conducive to the subsequent automation improvement of the entire production line. With the popularization of carbon molecular sieves, the amount of carbon molecular sieves used has increased, and the existing heating furnaces have been able to fully meet market demand.

[0009] In the aforementioned carbon molecular sieve carbonization continuous furnace, water is injected into the container, and the lower end of the oil discharge port extends below the liquid level of the container.

[0013] By arranging an oil discharge port at the bottom of the feed bin, the oily substances in the carbonization fume of the semi-finished product will not overflow from the feed bin to the heating tube, thus ensuring the good carbonization quality of the semi-finished product.

[0014] In summary, the utility model has the advantages of high production efficiency, being beneficial to the subsequent automation improvement of the entire production line, low maintenance frequency and good carbonization quality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0019] Embodiment. A continuous furnace for carbonizing a carbon molecular sieve, such as Figure 1 As shown, it includes a long strip furnace body 1, which is fixed to the ground. A heating tube 2 is arranged in the furnace body 1, and both ends of the heating tube 2 extend outward to the outside of the furnace body 1. The heating tube 2 is rotatably connected to the furnace body 1, and a driving mechanism is arranged on the heating tube 2.

A sealing treatment should be performed between the heating tube 2 and the feeding bin, and a feeding hopper 7 is arranged on the feeding bin 6. The discharge end of the feeding hopper 7 extends into the heating tube 2, and a smoke extraction pipe 8 is arranged on the feeding bin 6.

[0020] The outer side of the heating tube 2 is provided with a plurality of axially distributed support rings 9 , and the bottom of the support ring 9 is provided with two support wheels 19 , which are connected to the ground through a support frame 10 , and the support wheels 19 are rotatably connected to the support frame 10 .

[0022] The bottom of the feed bin 6 is conical, and an oil discharge port 14 is provided at the lowest point of the feed bin 6. A container 15 with an open top is provided below the oil discharge port 14. Water is filled in the container 15, and the lower end of the oil discharge port 14 extends below the liquid level of the container 15. Due to the water seal effect, the outside air cannot enter the feed bin 6 through the oil discharge port 14, and the liquid in the feed bin 6 can enter the container 15.

[0023] The furnace body 1 is provided with an air inlet 16 and a smoke exhaust port 17, and the smoke exhaust port 17 is connected to the chimney. The heating unit includes a flame nozzle 18 fixed inside the furnace body 1, and the flame nozzle 18 is connected to a gas source through a pipeline, and the gas source is natural gas.

[0024] Working principle: The semi-finished material of carbon molecular sieve (carbon molecular sieve extruded material) is pumped into the feed hopper 7, discharged from the bottom of the feed hopper 7, and enters the heating tube 2. As a further optimization, a valve or a screw conveyor can be set at the bottom of the feed hopper 7 to achieve uniform speed output of the material.

[0025] The motor 13 drives the driving gear 12 to rotate, and the driving gear 12 drives the heating tube 2 to rotate through the outer gear ring 11. Under the action of the spiral feeding plate 4, the semi-finished product passes through the heating tube 2 and is discharged from the discharge port 5.

[0026] The natural gas burns at the flame nozzle 18, heats the heating tube 2, and carbonizes the semi-finished material in the heating tube 2, and the carbonized material is discharged from the discharge port 5.
