Description

Technical Field

[0001] The utility model relates to the technical field of raw material preheating furnaces, in particular to a raw material preheating furnace for zinc oxide production. Background Art

[0002] In the production process of zinc oxide, raw material preheating is a key step, which is directly related to the efficiency of subsequent reactions and product quality. The preheating furnace is designed to improve the overall efficiency and product quality of zinc oxide production by optimizing heat transfer efficiency, improving preheating uniformity and reducing energy consumption, thereby meeting the needs of modern industrial production for high efficiency, environmental protection and sustainable development.

[0003] However, the prior art still has the following problems:

[0004] First of all, in the existing technology, the zinc oxide production raw material preheating furnace often faces the problems of uneven heating and low efficiency. This is mainly due to the unreasonable design of the heating mechanism and the unstable installation of the heating box, which leads to uneven heat distribution and poor hot air discharge, affecting the temperature stability in the furnace.

[0005] Secondly, in traditional zinc oxide production raw material preheating furnaces, the air supply mechanism is often complex in structure and has low air supply efficiency, resulting in unstable hot air supply and affecting the preheating effect of the raw materials. In addition, unreasonable design of the air inlet and outlet systems may also cause energy waste and environmental pollution.

[0006] In response to the above problems, the inventors proposed a raw material preheating furnace for zinc oxide production to solve the above problems. Utility Model Content

[0007] In order to solve the problems of uneven heating, low efficiency, complex structure and unstable hot air supply often faced by raw material preheating furnaces for zinc oxide production, the purpose of the utility model is to provide a raw material preheating furnace for zinc oxide production.

[0008] In order to solve the above technical problems, the utility model adopts the following technical solutions: a raw material preheating furnace for zinc oxide production, comprising a box body, a box door is rotatably provided on one side of the box body, a heating mechanism is provided inside the box body, and the raw materials can be effectively preheated by the heating mechanism, a support frame is fixedly provided on one side of the box body, an air supply mechanism is fixedly provided on the upper end of the support frame, and the transmission of the heat source can be maintained by the air supply mechanism, the heating mechanism comprises two limit plates, a heating box is commonly provided on one side of the opposite surfaces of the two limit plates, a limit card plate used in conjunction with the two limit plates is fixedly provided on the upper end of the heating box, a heating pipe is fixedly provided on the inner surface of the box body, a plurality of heating air outlets are provided on the inner surface of the heating pipe, and an exhaust pipe is provided on one side of the inner surface of the box body.

[0009] Preferably, the air supply mechanism includes two fixed frames, a fixed base is commonly provided above the two fixed frames, a hot air blower is fixedly provided on the upper end of the fixed base, an air inlet pipe is fixedly provided on one side of the hot air blower, an air inlet port is fixedly provided on one side of the air inlet pipe, an air outlet pipe is fixedly provided on one side of the hot air blower, and an air outlet port is fixedly provided on one side of the air outlet pipe.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model ensures the stable installation and positioning of the heating box through the heating mechanism. The multiple heating air vents built into the heating pipe effectively improve the heating efficiency and uniformity. At the same time, the setting of the exhaust pipe promotes the discharge of hot air, which is conducive to maintaining the temperature in the furnace stable and improving the preheating effect and production efficiency of zinc oxide production raw materials.

[0012] 2. The utility model uses an air supply mechanism to firmly support the hot air blower with a fixed frame and a fixed base. The air inlet pipe and the air inlet ensure the effective intake of external air, while the air outlet pipe and the air outlet directly send the hot air into the heating pipe.
