Problems solved by technology

However, due to the large diameter of the rotary kiln and the rotation during operation, the conventional method is to use the rotary joint to transport the cooling water to the cooling water chamber, and then discharge it through the rotary joint after heat exchange. The disadvantage of this method is that the structure is complex and the rotation The service life of the joint is short and needs to be replaced frequently, which greatly reduces the working efficiency of the rotary kiln and increases the operating cost of the rotary kiln
There is also a method of spraying, which can only cool the shell of the rotary kiln, which is easy to pollute the environment and cause waste of water resources, and cannot cool the components in the rotary kiln, which has great limitation

Embodiment 1

[0026] Embodiment one: if figure 1 As shown, the rotary kiln cooling device is used to cool the shell of the rotary kiln 1, and includes a cooling water chamber 2 arranged on the shell of the rotary kiln 1, and the cooling water chamber 2 is divided into eight cooling water chambers. cavity 2, the cooling water cavity 2 is respectively provided with a water inlet device and a water return device. In this embodiment, the water inlet device includes eight water inlet pipes 3 fixedly arranged radially along the outer circumference of the rotary kiln 1, the water inlet pipes 3 communicate with the corresponding cooling water chambers 2, and the water inlet pipes 3 A water bucket 4 is installed at the outer end, and a water intake tank 5 is provided at a position corresponding to the water bucket 4 below the rotary kiln 1 .

[0027] In this embodiment, the water inlet device doubles as the water return device, the water inlet pipe 3 doubles as a water return pipe, and the water in...

Embodiment 2

[0029] Embodiment two: if Figure 4 As shown, the rotary kiln cooling device is used to cool the slag claws 6 extending into the rotary kiln 1, and includes a cooling water chamber 2 arranged in the cooling slag claws 6 of the rotary kiln. The cooling water chamber 2 There are water inlet device and water return device respectively. In this embodiment, the water inlet device includes eight water inlet pipes 3 fixedly arranged radially along the outer circumference of the rotary kiln 1, the water inlet pipes 3 communicate with the corresponding cooling water chambers 2, and the water inlet pipes 3 A water bucket 4 is installed at the outer end, and a water intake tank 5 is provided at a position corresponding to the water bucket 4 below the rotary kiln 1 . The structure and function of the slag claw 6 are not the focus of the present invention, and do not affect the disclosure of the present invention, so no detailed description will be given.

[0030] In this embodiment, the...

Embodiment 3

[0032] Embodiment three: as Figure 7 , Figure 8 and Figure 9 As shown, this embodiment has the same purpose as Embodiment 2, and the structure is basically the same, the difference is that: a water storage plate 7 is provided in the cooling water chamber 2; the function of the water storage plate 7 is to follow the With the rotation of the rotary kiln 1, when the cooling water gradually flows out to the water bucket 4 through the water inlet pipe 3 by gravity, a part of the cooling water is kept in the cooling water chamber 2, so that it will not be caused by the lack of cooling water in some positions. The components in the rotary kiln 1 are ablated and damaged; as the rotary kiln 1 rotates, when the cooling water gradually enters the cooling water cavity 2 through the water bucket 4 and the water inlet pipe 3 by gravity, the The water storage plate 7 prevents the remaining cooling water from flowing out and mixes with the new cooling water to keep the cooling temperatur...

Abstract

The invention discloses a rotary kiln cooling device, which is used for cooling rotary kiln parts. The rotary kiln cooling device comprises a cooling water chamber arranged on a rotary kiln part cooling part, the cooling water chamber is provided with a water inlet device and a water return device, the water inlet device comprises a water inlet pipe fixedly arranged along the periphery of a rotary kiln, the water inlet pipe is communicated with the cooling water chamber, the outer end part of the water inlet pipe is provided with a water bucket, and a water taking tank is arranged below the rotary kiln and corresponding to the position of the water bucket. According to the invention, through using the rotary characteristics of rotary kilns and using the principle of irrigation waterwheels, cooling water is filled in the cooling water chamber; the rotary kiln cooling device is simple in structure; no other power and mutual friction components are adopted; and the device is extremely reliable in use.

Description

technical field [0001] The invention relates to a rotary kiln, in particular to a cooling device for the rotary kiln. Background technique [0002] The rotary kiln is widely used and works at high temperature. The service life of the shell and the inner parts of the shell is short, and the failure rate is extremely high. Therefore, the cooling system is often added to improve the service life of the rotary kiln. However, due to the large diameter of the rotary kiln and the rotation during operation, the conventional method is to use the rotary joint to transport the cooling water to the cooling water chamber, and then discharge it through the rotary joint after heat exchange. The disadvantage of this method is that the structure is complex and the rotation The joint has a short service life and needs to be replaced frequently, which greatly reduces the working efficiency of the rotary kiln and increases the operating cost of the rotary kiln. There is also a method of sprayi...
