Description

Technical Field

[0001] The utility model relates to the technical field of chain grate machine anti-blocking and cleaning, in particular to a dust cleaning structure for quickly cleaning the blockage of a shovel plate of a chain grate machine. Background Art

[0002] The chain grate rotary kiln system is an effective clinker production process. During operation, a shovel plate located above the chain grate plate is usually used to help the material be evenly distributed and pushed forward during the movement of the chain grate. However, in actual use, the shovel plate of the sintering chain grate is easily blocked. After blockage, cleaning is complicated, time-consuming and labor-intensive. The cleaning effect is not very ideal and the shovel plate is not easy to recover after blockage. There are many inconveniences in the existing cleaning methods. When the shovel plate of the sintering chain grate is blocked, one of the traditional cleaning methods is to stop the operation of the entire equipment, and then send staff to enter the equipment through the manhole to directly clean the blocked shovel plate manually. Although this method is direct, it has the following problems: long downtime, during which normal production cannot be carried out, which has a great impact on production efficiency and output; the internal environment of the equipment may be harsh, with dangerous factors such as high temperature and dust, posing a threat to the health and safety of workers; another cleaning method is to use a cleaning device with a shovel head to clean from both sides of the chain grate. Due to the structure of the chain grate and the position of the shovel plate, there may be poor angles when cleaning from both sides, resulting in poor cleaning effect. Utility Model Content

[0019] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0020] Embodiment 1 of the cleaning structure for quickly cleaning the blockage of the shovel plate of the chain grate provided by the utility model:

[0021] like Figure 1 to Figure 2 As shown,

[0022] It includes a chain grate 1 and a kiln structure 2 for sintering and drying materials conveyed by the chain grate 1. The top refractory layer 21 of the kiln structure 2 is located above the grate plate of the chain grate and a cleaning hole tube 22 is vertically arranged on the top refractory layer 21. The cleaning hole tubes 22 are a plurality of spaced-apart cleaning hole tubes 22. A shovel plate 11 is provided above the grate plate of the chain grate. The shovel plates 11 are a plurality of parallel arranged shovel plates. The central axis of the cleaning hole tube 22 is located between two adjacent shovel plates 11.

[0023] The lower end of the cleaning hole pipe 22 is on the same horizontal plane as the lower surface of the top refractory layer 21 .

[0024] The cross section of the cleaning hole tube 22 is circular and the diameter of the circle is 25 cm.

[0025] Specifically, when constructing the refractory material on the top refractory layer 21 of the chain grate, a cleaning hole tube 22 is welded on the top, which is evenly divided into five positions. The axis of each cleaning hole tube 22 is located between two shovel plates 11, and then the cleaning hole tube 22 is surrounded during the pouring construction. During normal production, the operator can use a cleaning shovel to reach into the cleaning hole tube 22 to clean the blocked pellets on the shovel plate 11. The problem can be solved by simple operation without stopping the machine.

[0026] In this embodiment, the top end of the cleaning hole pipe 22 extends out of the top refractory layer 21 , and a detachable hole cover 23 is provided at the upper end of the cleaning hole pipe 22 .

[0027] The hole blocking cover 23 includes a blocking block 231 extending into the cleaning hole tube 22 and a limiting plate 232 arranged at the top of the blocking block 231. The top of the limiting plate 232 is provided with an action piece 233 for hand-holding. The diameter of the limiting plate 232 is larger than the diameter of the cleaning hole tube 22.

[0028] The cross section of the blocking block 231 is trapezoidal, and the length of the bottom side of the trapezoid is smaller than the length of the top side.

[0029] Specifically, the plugging cover 23 can prevent dust, debris or other substances from entering the kiln body through the cleaning hole tube 22 when the kiln body structure 2 is in operation or not in use, thereby maintaining the cleanliness and stability of the kiln body, avoiding interference with production or safety hazards, and avoiding excessive heat loss.

[0030] The limiting plate 232 of the hole plugging cover 23 is provided with a hand-held action piece 233, so that the operator can easily hold the action piece to operate when installing or removing the hole plugging cover, thereby improving the convenience and safety of the operation.

[0031] The utility model sets spaced cleaning hole tubes 22 on the top refractory layer 21 of the kiln body structure 2, and the central axes of these cleaning hole tubes 22 are located between two adjacent shoveling plates 11, so that the operating workers can directly clean the blocked pellets on the shoveling plates 11 through these cleaning hole tubes 22. Compared with the traditional cleaning method, the operating difficulty is reduced and the labor intensity of the operating workers is reduced. In addition, the structure of the utility model can ensure the normal operation of the chain grate machine, avoid shutdown for cleaning, improve production efficiency and stability of equipment operation, and reduce the maintenance cost of the equipment as a whole.
