Description

Technical Field

[0001] This utility model relates to the technical field of rotary kilns, and in particular to a rotary kiln waste heat recovery device. Background Technology

[0002] A rotary kiln is a cylindrical piece of equipment, usually placed horizontally or slightly inclined. It uses rotational motion to perform heat treatment and chemical reactions on materials. Depending on the materials being processed, rotary kilns can be classified into various types, such as cement kilns, metallurgical and chemical kilns, and lime kilns. Rotary kilns are typically used in conjunction with waste heat recovery devices to improve energy efficiency, reduce production costs, and minimize environmental pollution.

[0003] When recovering waste heat from a rotary kiln using a waste heat recovery device, the waste heat is usually mixed with some dust particles. Over a long period of time, these dust particles may cause blockage inside the waste heat recovery device, thus affecting its normal use. Therefore, relevant personnel will install some dustproof nets inside to prevent dust. However, relying solely on a single dustproof net cannot achieve a good dust prevention effect. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a rotary kiln waste heat recovery device. When recovering waste heat from the rotary kiln through the waste heat recovery device, multiple dustproof nets work together and the filter holes on the filter plate are staggered to better prevent dust from entering the interior of the rotary kiln and causing blockage, thus affecting its normal use.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The rotary kiln waste heat recovery device of this utility model is described below with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, the rotary kiln waste heat recovery device of this utility model embodiment includes: a waste heat recovery unit 1 and a filter assembly 2.

[0023] The filter assembly 2 includes an installation assembly 21, a first filter plate 22, a first filter screen 23, a second filter plate 24, a second filter screen 25, an installation ring 26, and a filter element 27. The installation assembly 21 is located inside the waste heat recovery unit 1. The installation assembly 21, the first filter plate 22, the first filter screen 23, the second filter plate 24, the second filter screen 25, and the installation ring 26 are sequentially installed in the installation assembly 21, and the filter element 27 is installed in the installation ring 26.

[0024] Mounting component 21 includes a connecting ring 211 and a handle 212.

[0025] The connecting ring 211 is located inside the waste heat recovery unit 1, and the handle 212 is located inside the connecting ring 211.

[0026] The waste heat recovery unit 1 includes a body 11, a heat inlet pipe 12, and a connecting pipe 13.

[0027] The heat inlet pipe 12 is disposed on the outer wall of the vessel body 11, and the connecting pipe 13 is disposed on the outer wall of the vessel body 11 adjacent to the heat inlet pipe 12.

[0028] Specifically, when it is necessary to recover heat from the rotary kiln through the waste heat recovery unit 1, relevant personnel can connect the rotary kiln to the vessel body 11 through the heat inlet pipe 12 to recover heat.

[0029] During the recovery process, the heat first passes through filter element 27, where filter element 27 performs the first layer of filtration on the dust and particles that have gathered in the heat. The heat passing through filter element 27 continues to pass through the second filter screen 25, where it undergoes a second filtration. The heat passing through the second filter screen 25 then passes through the second filter plate 24 and undergoes a third filtration, before passing through the first filter plate 22. The filter holes on the first filter plate 22 and the second filter plate 24 are staggered, which can reduce the entry of some fine dust particles into the container 11, which could cause blockage due to long-term accumulation.

[0030] When the internal filtration mechanism needs to be cleaned, the relevant personnel can rotate the handle 212 to rotate the connecting ring 211 and remove it from the inside of the heat inlet pipe 12. Then, the first filter plate 22, the first filter screen 23, the second filter plate 24, the second filter screen 25 and the mounting ring 26 are rotated in sequence to remove them for cleaning or replacement.

[0031] A sealing gasket 3 is provided at the other end of the connecting pipe 13.

[0032] It is understandable that by setting the sealing gasket 3, the connection point of the device 11 can be sealed during the process of connecting it to other devices through the connecting pipe 13.

[0033] A sealing ring 4 is provided on the inner wall of the heat inlet pipe 12, and the sealing ring 4 is fitted on the outer wall of the connecting ring 211.

[0034] It is understandable that the sealing ring 4 provided on the inner wall of the heat inlet pipe 12 can seal the connection point between the connecting ring 211 and the heat inlet pipe 12.

[0035] In summary, the rotary kiln waste heat recovery device of this utility model, when recovering waste heat from the rotary kiln, relies on multiple dustproof nets working together and the filter holes on the filter plate being staggered to prevent dust from entering the interior of the rotary kiln and causing blockage, thus affecting its normal use.
