Abstract
Description
Technical Field
[0001] This utility model relates to the field of kiln waste heat recovery technology, specifically a kiln waste heat recovery heating device. Background Technology
[0002] A kiln is a furnace used to fire ceramics and sculptures or to fuse enamel onto the surface of metal objects. It is generally made of bricks and stones and can be made in various sizes as needed. Since kilns emit a large amount of high-temperature flue gas during operation, they are usually equipped with waste heat recovery devices to achieve the recovery and reuse of waste heat in order to save energy and protect the environment.
[0003] In existing technologies, flue gas is typically sent to the heating tubes inside the recovery device to heat the water within the device, thus recovering waste heat for heating. However, during actual use, as the recovery process continues for a long time, a lot of scale will accumulate on the surface of the heating tubes, reducing the efficiency of waste heat recovery. Furthermore, disassembling the heating tubes is cumbersome, making it inconvenient to disassemble and clean them in a timely manner, which has certain limitations. Therefore, it is necessary to improve the kiln waste heat recovery heating device to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a kiln waste heat recovery and heating device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a kiln waste heat recovery and heating device, comprising a recovery box and a cover plate, wherein a heating pipe is fixedly installed inside the cover plate, a water inlet pipe is fixedly installed at the left end of the recovery box, a water outlet pipe is fixedly installed at the right end of the recovery box, a positioning mechanism is provided outside the recovery box, and a purification mechanism is provided on the top of the cover plate.
[0006] Preferably, the positioning mechanism includes a positioning plate, which is fixedly installed at the bottom of the cover plate and slidably installed on the inner wall of the recycling bin. A support column is fixedly installed on the inner side of the positioning plate, and a support seat is fixedly installed on the outside of the recycling bin. A rotating plate is rotatably installed inside the support seat, and a horizontal plate is fixedly installed on the top of the rotating plate. A first threaded post is threaded inside the horizontal plate, and a pressure block is rotatably installed at the bottom of the first threaded post. A limit plate is fixedly installed on the outside of the pressure block, and a positioning frame is fixedly installed on the top of the cover plate. The pressure block is slidably installed on the inner wall of the positioning frame to facilitate positioning of the top of the cover plate.
[0007] Preferably, a through groove is provided inside the rotating plate at a position corresponding to the limiting plate, and the limiting plate is slidably installed in the through groove to facilitate the limiting operation of the pressure block.
[0008] Preferably, a through groove is provided inside the positioning frame at a position corresponding to the limiting plate, and the limiting plate is slidably installed in the through groove to facilitate the lifting and lowering of the limiting plate.
[0009] Preferably, the purification mechanism includes a purification box, which is fixedly installed on the top of a cover plate. The heating tube is fixedly installed with the purification box. A placement seat is fixedly installed on the inner wall of the purification box. A purification plate is slidably installed inside the placement seat. An exhaust pipe is fixedly installed at the right end of the purification box. A positioning column is slidably installed inside the purification box. A sealing cover is fixedly installed on the top of the positioning column. A handle is fixedly installed on the top of the sealing cover. A second threaded column is rotatably installed inside the horizontal plate. A threaded plate is threaded on the outer thread of the second threaded column. An L-shaped pressure plate is fixedly installed on the top of the threaded plate. A limit post is fixedly installed on the outer side of the L-shaped pressure plate. The limit post and the sealing cover are slidably installed to facilitate the purification of flue gas.
[0010] Preferably, a through groove is provided inside the horizontal plate at the position corresponding to the L-shaped pressure plate, and the L-shaped pressure plate is slidably installed in the through groove to facilitate the lifting and lowering of the L-shaped pressure plate.
[0011] Compared with the prior art, this utility model provides a kiln waste heat recovery and heating device, which has the following beneficial effects:
[0012] 1. This kiln waste heat recovery heating device, through its positioning mechanism, facilitates the positioning of the cover plate during use via the positioning plate. With the support column, it supports the heating tubes. By rotating the first threaded column, with the assistance of the limiting plate, the pressure block moves upward, moving away from the positioning frame. This facilitates the rotation of the horizontal plate and the rotating plate, allowing for quick release of the cover plate's limiting function and easy disassembly. The device is easy to operate and allows for timely cleaning of the heating tube surface, ensuring efficient waste heat recovery.
[0013] 2. This kiln waste heat recovery heating device, through its purification mechanism, facilitates the purification of flue gas during use via a purification plate. When the purification plate needs to be disassembled and cleaned, rotating the second threaded column allows the threaded plate and L-shaped pressure plate to move upwards, thus allowing the limiting column to move away from the sealing cover and releasing the limiting function of the sealing cover. This facilitates the lifting of the sealing cover and the disassembly of the purification plate. After the purification plate is installed, the positioning column facilitates the quick positioning of the sealing cover. Attached Figure Description

[0028] Example 2:
[0029] Please see Figure 5Furthermore, in conjunction with Embodiment 1, the purification mechanism 7 includes a purification box 701, which is fixedly installed on the top of the cover plate 2. The heating tube 3 is fixedly installed with the purification box 701. A placement seat 702 is fixedly installed on the inner wall of the purification box 701.
