Description

Technical Field

[0001] The present application relates to the technical field of heating furnaces, and in particular to a vertical heating furnace. Background Art

[0002] A heating furnace is a device widely used in metal processing, petroleum refining and chemical industry, electronic manufacturing, laboratory research and other fields. It completes heating by converting various energies into heat energy and transferring it to the object to be heated.

[0003] Heating furnaces are divided into vertical heating furnaces and horizontal heating furnaces. In the chemical industry, heating furnaces are mainly used to heat liquid or gas raw materials. Therefore, vertical heating furnaces are usually used. By placing a heat source at the bottom of the heating furnace, the air temperature in the furnace body is increased, and a heat conduction pipe is arranged in the middle or upper part of the furnace body. The liquid or gas to be heated flows through the pipe at a certain flow rate. The heated hot air will move upward to complete the heating of the heat conduction pipe, so that the raw materials can be better used and meet the temperature required for production.

[0004] When using the heating furnaces currently used in the chemical industry, due to the large number of raw materials to be heated each time, it is usually necessary to arrange multiple heating furnaces at the same time to heat multiple raw materials at the same time. However, this method is costly, so the number of heating furnaces usually arranged is less than the number of raw materials.

[0005] Therefore, when the heating furnace is used, different raw materials need to be replaced. However, before heating different raw materials, it is usually necessary to clean the heat transfer pipe used last time to prevent the raw materials from remaining in the heat transfer pipe and affecting subsequent production.

[0006] Therefore, it is necessary to provide a vertical heating furnace with a detachable heat-conducting pipe to solve the above problems.

[0019] Among them, when heating different raw materials, it is suitable to remove and replace the heat conduction box.

[0020] When the technical solution of the utility model is implemented, by setting the heat transfer box and the outer shell to be detachably connected, when heating different raw materials, it is only necessary to replace the heat transfer box, and there is no need to flush the heat transfer tube, thereby preventing raw material residue from appearing in the heat transfer tube.

[0021] Furthermore, two sets of guide rails are arranged on the side of the heat conduction box, and guide grooves are correspondingly arranged on the inner side of the outer shell, and the guide rails are suitable for sliding along the guide grooves to realize the movement of the heat conduction box.

[0044] like Figure 2 As shown, in order to provide a heat source for the heating chamber of the furnace body 2, a heating mechanism is provided on the base 21, and the heating mechanism is a burner 22, and the burner 22 has a combustion end, and the combustion end is suitable for extending into the heating chamber of the furnace body 2, so as to heat the air in the heating chamber, and the burner 22 is connected to a fuel and a control system, and the control system controls the fuel to pass into the burner 22, so as to realize the combustion of the burner 22;

[0045] In some other embodiments of the utility model, the heating mechanism may also be a radiation heater, a steam heater, an electric heater, etc., which is not limited in the present embodiment;

[0046] Since the heating mechanism is arranged at the bottom of the furnace body 2, uneven heat may occur during operation.
