AI Technical Summary
Traditional reciprocating grate devices cannot operate normally due to the expansion and jamming of the grate bars, and there are also problems such as material leakage, slag leakage and inconsistent material combustion.
An intermediate buffer is set between adjacent grate bars. The buffer plate and spring absorb the expansion and deformation of the grate, ensuring smooth movement of the grate bars. The intermediate buffer is designed to achieve flexible contact and avoid jamming.
This ensures the normal operation of the grate bars, avoids material and slag leakage, guarantees uniform combustion of materials, and reduces manufacturing costs.

Abstract
Description
Technical Field
[0001] This utility model relates to grate structures, and in particular to a reciprocating grate device with an intermediate buffer. Background Technology
[0002] When incinerating combustibles such as garbage, incineration equipment with an internal grate structure is required, namely a reciprocating grate device. The reciprocating grate is the core component of the incineration equipment. It is mainly used to support fuel (such as solid waste, biomass, etc.) and achieve efficient and complete combustion of fuel by controlling air flow, fuel movement and combustion rate.
[0003] Some incineration equipment requires the installation of multiple grate spans, with adjacent spans separated by intermediate wall panels. However, during operation, the equipment will inevitably expand due to heat. Since the effective inner diameter of the grate is fixed, when the overall width of the grate bars exceeds the effective width of the grate, the grate bars will jam, causing the equipment to malfunction.
[0004] Traditionally, to avoid the above situations, a sufficiently large gap needs to be reserved between two adjacent furnace bars before they leave the factory. This can lead to material leakage and slag leakage. In some cases, the gaps may be large in some areas and small in others during operation, resulting in inconsistent material combustion (i.e., some materials are completely burned while others are not).
[0005] Therefore, a method or apparatus is needed to solve the above problems. Summary of the Invention
[0006] The present invention addresses the aforementioned shortcomings of the existing technology by proposing a reciprocating grate device that is simple in structure, ingenious in design, and reasonable in layout, and that ensures the smooth operation of the movable grate plates without jamming during movement without affecting the air supply effect.
[0007] The technical solution of this utility model is: a reciprocating grate device with intermediate buffers, characterized in that: the grate device includes a multi-span grate body 1, an intermediate wall plate 2 is provided between adjacent grate bodies 1, and multiple intermediate buffers 3 are provided on the top of the intermediate wall plate 2.
[0008] The intermediate buffer 3 includes an intermediate support block 4 fixedly connected to the intermediate wall panel 2. Buffer grooves 5 are respectively provided on both sides of the intermediate support block 4. A buffer plate 6 is movably connected within each buffer groove 5. Two through holes 7 are symmetrically provided on the intermediate support block 4, and springs 8 are installed within each through hole 7. A connecting end 9 is provided on the inner wall of the buffer plate 6, and the buffer plate 6 is connected to the end of the spring 8 through the connecting end 9.
[0009] The grate body 1 includes a plurality of grate plates 10, the edges of which are in contact with the buffer plate 6 in the intermediate buffer 3.
[0010] The spring 8 is a high-temperature resistant spring.
[0011] Compared with the prior art, this utility model has the following advantages:
[0012] This type of reciprocating grate device with intermediate buffers is simple in structure, ingeniously designed, and rationally laid out. It addresses the problems existing in traditional grate devices by incorporating a unique structure. Multiple intermediate buffers, contacting the sides of the grate body, are installed on the wall between adjacent grate sections. The buffer plates within these intermediate buffers can displace laterally (perpendicular to the direction of grate movement), and springs inside the buffer plates absorb the displacement caused by thermal expansion of the grate. This creates a flexible contact between the grate sections and the intermediate buffers, ensuring the normal operation of the moving grate sections and the reciprocating grate device. Furthermore, the device is simple to manufacture and inexpensive, thus possessing numerous advantages and being particularly suitable for widespread application in this field, with a very broad market prospect.

[0015] Figure 3 This is a side view of the intermediate buffer in an embodiment of this utility model. Detailed Implementation
[0016] The specific embodiments of this utility model will be described below with reference to the accompanying drawings. Figures 1 to 3 As shown: A reciprocating grate device with intermediate buffers includes a multi-span grate body 1, intermediate wall plates 2 are arranged between adjacent grate bodies 1, and multiple intermediate buffers 3 are arranged on the top of the intermediate wall plates 2.
[0017] The intermediate buffer 3 includes an intermediate support block 4 fixedly connected to the intermediate wall panel 2. Buffer grooves 5 are respectively provided on both sides of the intermediate support block 4. A buffer plate 6 is movably connected within each buffer groove 5. Two through holes 7 are symmetrically provided on the intermediate support block 4, and springs 8 are installed within each through hole 7. A connecting end 9 is provided on the inner wall of the buffer plate 6, and the buffer plate 6 is connected to the end of the spring 8 through the connecting end 9.
[0018] The grate body 1 includes a plurality of grate plates 10, the edges of which are in contact with the buffer plate 6 in the intermediate buffer 3.
[0019] The spring 8 is a high-temperature resistant spring.
[0020] The working process of this type of reciprocating grate device with intermediate buffer is as follows: Intermediate buffers 3 are set between adjacent grate bodies 1, that is, the sides of these grate bodies 1 are in contact with the intermediate buffers 3. When the grate body 1 is heated and deformed, it will push the buffer plate 6 to move in the buffer groove 5, and the spring 8 will be compressed accordingly, thereby ensuring that the grate body 1 will not be stuck between the intermediate wall plates 2 on both sides (or the intermediate wall plate 2 and the inner wall of the combustion device) due to deformation; the movable grate plates in the grate body 1 rub against the buffer plate 6 when moving.
[0021] When the incineration device is not working for a period of time, the temperature of the grate body 1 drops and returns to the initial state. At this time, the buffer plate 6 returns to the initial position under the action of the spring 8. That is, the buffer plate 6 is always in contact with the side of the grate body 1. Since this device has such a buffering and resetting structure, it is not necessary to leave a large gap between adjacent grate plates, thereby avoiding the problem of material leakage and slag leakage, and also effectively ensuring the consistency of material combustion.
[0022] It should be noted that the intermediate buffer 3 described in this device can also be set on the side wall of the incineration device. That is, both sides of the grate body 1 at the side span (the side closer to other grate bodies 1 and the side closer to the inner wall of the incineration device) are in contact with the intermediate buffer 3. Even if the intermediate buffer is not set on the side wall of the incineration device, the intermediate buffer 3 on the other side of the grate body 1 can absorb the deformation caused by the thermal expansion of the grate body 1.
