Description
Technical Field
[0001] This utility model relates to the field of ceramic kiln technology, specifically to an energy-saving ceramic kiln with precise temperature control. Background Technology
[0002] A kiln is a firing tool used to fire ceramics or fuse enamel to the surface of metal objects. It is generally constructed of brick and stone and can be made in various sizes to meet specific needs. It can be powered by combustible gas, oil, or electricity. Electric kilns are easier to control in terms of temperature than kilns using combustible gas or oil, but some potters and sculptors believe that the temperature rises too quickly in electric kilns. The temperature inside the kiln is measured using a pyrometer or thermometer cone and can be observed through a peephole.
[0003] Currently, during the use of kilns, the relatively enclosed kiln area results in a low oxygen content inside. This often leads to incomplete combustion of fuel during the kiln's operation, producing smoke. Furthermore, the smoke generated during the kiln's production process often contains a large amount of heat, which is frequently released with the smoke, thus causing energy loss.
[0004] Existing methods recover heat through heat exchange equipment, but during long-term smoke transport, dust adheres to the heat exchange tubes and cannot be automatically cleaned, affecting heat exchange efficiency. Therefore, there is an urgent need to design an energy-saving ceramic kiln with precise temperature control to solve the above problems. Utility Model Content

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0031] like Figure 1-7 As shown in the figure, the present invention provides an energy-saving ceramic kiln with precise temperature control, including a furnace chamber 3, and a heat collection hood 4 installed above the furnace chamber 3 to collect the flue gas and heat energy at the top of the furnace chamber 3. The heat collection hood 4 is connected to the top of the furnace chamber 3 and is used at least to recover the heat of the flue gas inside the furnace chamber 3.
[0032] The upper part of the heat collection hood 4 is provided with a scraper assembly 6, which is used at least to clean the soot adhering to the inner wall of the top of the heat collection hood 4.
[0033] Self-closing seals 7 are provided on both sides of the top of the heat collector 4. The self-closing seals 7 are used to seal the top of the heat collector 4 at least.
[0034] The heat collection hood 4 is provided with ash discharge bins 8 on both sides, which cover the outer walls of the furnace 3. The top of the ash discharge bins 8 is connected to the inside of the heat collection hood 4.
[0035] In one embodiment of this utility model, a frame 1 is provided below the furnace chamber 3, and roller modules 2 are arranged in parallel on the top of the frame 1. The roller modules 2 include a lower drive wheel and an upper roller. The roller can be used to transport ceramic products and realize high-temperature sintering of ceramic products inside the furnace chamber 3.
[0036] In another embodiment of this utility model, both ends of the heat collection cover 4 are fixedly installed with recovery pipes 5 extending to the bottom of the furnace 3, and the recovery pipes 5 transport the collected heat to the heating device at the bottom of the furnace 3.
[0037] In another embodiment of this utility model, through holes 41 are provided on both sides of the top of the heat collection hood 4, and a recovery chamber 42 is provided in the upper middle part of the heat collection hood 4. An extension plate 43 is fixedly installed on both sides of the recovery chamber 42. The extension plate 43 is fixed on the outer wall of the top of the furnace 3. The extension plate 43 increases the area of the heat collection hood 4 for collecting flue gas and heat energy, thereby improving the heat collection effect.
[0038] In one embodiment of this utility model, the scraper assembly 6 includes a synchronization frame 61 located above the heat collection hood 4. A handle 62 is fixedly installed on the outer wall of the top of the synchronization frame 61, and a scraper 63 located inside the heat collection hood 4 is installed at the bottom of the synchronization frame 61. A dust collection hopper can be suspended below the scraper, so that the dust scraped off by the scraper 63 is collected by the dust collection hopper. The scraper 63 is in close contact with the inner wall of the top of the heat collection hood 4. When the operator holds the handle 62, the synchronization frame 61 can slide on the top of the heat collection hood 4. At the same time, the synchronization frame 61 drives the scraper 63 to slide close to the inner wall of the top of the heat collection hood 4, and the scraper 63 is used to clean the dust on the inside of the top of the heat collection hood 4.
[0039] In another embodiment of this utility model, the self-closing seal 7 includes a corrugated telescopic cover 71. One end of the corrugated telescopic cover 71 is fixedly installed with a connecting block 72 connected to the scraper assembly 6. The connecting block 72 is connected to the side wall of the synchronous frame 61. At the same time, when the synchronous frame 61 moves, it can drive the corrugated telescopic cover 71 to move synchronously.

[0041] In another embodiment of this utility model, the ash discharge bin 8 includes sealing plates 81 fixed to the bottom of both ends of the heat collection hood 4. The sealing plates 81 are fixedly attached to the outer walls of both sides of the furnace 3. An ash discharge port 82 is formed between the bottom end of the sealing plate 81 and the furnace 3. When the scraper assembly 6 scrapes the ash on the inner wall of the top of the heat collection hood 4 to both sides of the heat collection hood 4, the scraper 63 is shaken, causing the ash collection hopper below the scraper 63 to shake, so that the ash inside the ash collection hopper falls into the sealing plate 81 and is discharged from the ash discharge port 82.
[0042] Working steps: 1. The heat collection cover 4 can collect the heat energy and flue gas inside the furnace 3, and the heat energy is circulated to the heating device at the bottom of the furnace 3 through the recovery pipe 5, so as to better control the temperature of the furnace 3.
[0043] 2. After the heat collection cover 4 has been working for a period of time, dust will adhere to the inner wall of the heat collection cover 4. The operator can use the scraper assembly 6 to scrape off the dust.
[0044] Third, when the scraper assembly 6 moves, the self-closing seal 7 moves together with the scraper assembly 6 to achieve a self-closing seal on the top of the heat collection cover 4.
[0045] Fourth, when the scraper assembly 6 is about to move to the side of the heat collection cover 4, the guide rod 74 extends and is limited by the limiting head 75.
[0046] The foregoing description only illustrates certain exemplary embodiments of the present invention.
