Problems solved by technology

Because the burner is located at one end of the kiln body, when the kiln body is long, it is difficult to control the temperature of each section in the length direction of the kiln body, and it is difficult to take into account factors such as equipment productivity, temperature distribution in the kiln body, and firing atmosphere at the same time. The productivity of the cross-sectional area is low, and the energy consumption per unit of finished product is high
[0004] In order to solve this problem, the patent No. 2017218534981 discloses a swing kiln, which solves the problem of inaccurate temperature control by setting the burner on the side wall of the kiln body, but the kiln body only It can swing, but cannot turn, and is greatly restricted in use

Embodiment 1

[0032] Such as figure 1 As shown, a rotary kiln capable of segmented temperature control includes a kiln body 1 , a kiln tail cover 2 is provided at the left end of the kiln body 1 , and a kiln head cover 3 is provided at the right end of the kiln body 1 . A base 4 is provided under the kiln body 1 , and the base 4 is rotatably connected to the kiln body 1 .

[0033] As a specific implementation, at least two wheel belts 14 are arranged on the kiln body 1 described in this embodiment, and two tires for bearing are arranged symmetrically under each wheel belt 14 on the base 4 . The support roller 41 of the kiln body 1 is supported, and the tire belt 14 is pressed against the support roller 41 .

[0034] The kiln tail cover 2 is provided with a feed port 21, and the feed port 21 communicates with the kiln body 1 through a feed pipe 22, and the feed pipe passes through the kiln tail The cover 2 extends to the inside of the kiln body 1 . The lower end of the kiln head cover 3 ...

Embodiment 2

[0045] Such as Figure 7 As shown, the rotating section 73 is arranged inside the kiln head cover 3 and arranged coaxially with the kiln body 1, and the right end of the rotating section 73 extends through the kiln head cover 3 to The outside of the kiln head cover 3 .

[0046] Further, since the temperature in the kiln body 1 at the feed end is lower than the discharge end during operation, and when the rotating section 73 is set in the kiln head cover 3, if the The connecting section 72 is arranged in the kiln body 1, and there is a potential safety hazard in a high-temperature environment. For this, as Figure 7 As shown, the connecting section 72 is arranged in the kiln head cover 3, and one end of the connecting section 72 is connected with the end of the rotating section 73, and the other end of the connecting section 72 is connected with the The ends of the supply section 71 are connected, and the ends of the supply section 71 extend into the kiln head cover 3 . Pre...

Abstract

The invention discloses a rotary kiln with a segmented temperature control. The kiln comprises a kiln body, a kiln head cover, a kiln tail cover, a base and a first fuel supply pipe formed by a supplysection, a connecting section and a rotating section; a drive device is arranged between the base and the kiln body; the supply section is fixedly arranged on the outer side wall of the kiln body; the rotating section and the kiln body are coaxially arranged and are connected with a fuel supply source through a rotary joint; the supply section and the rotating section are communicated with each other through the connecting section; the outer side wall of the kiln body is provided with multiple groups of combustion components; and fuel inlets of the combustion components are connected with thesupply section of the first fuel supply pipe through branch pipes respectively. The rotary kiln can realize segmented temperature control to enable control of a temperature field in the kiln body tobe accurate, is more convenient to control the temperature field compared with the traditional rotary kiln and is improved in heat efficiency and productivity.

Description

technical field [0001] The invention relates to a kiln, in particular to a rotary kiln capable of temperature control in sections. Background technique [0002] In many production industries such as building materials, metallurgy, chemical industry, environmental protection, etc., rotary cylinder equipment is widely used for mechanical, physical or chemical treatment of solid materials. This type of equipment is called rotary kiln. Its technical performance and operating conditions vary greatly To a certain extent, it determines the product quality and production cost of the enterprise. The structure of the existing rotary kiln is as follows: Figure 8 shown. [0003] The kiln body is supported by supporting wheels, and the driving device drives the kiln body to rotate around its axis. The burner is located at one end of the kiln body to provide the required heat for the establishment of the temperature field in the kiln body. The material is fed into the kiln body from t...
