[0001] This utility model relates to the field of printing and dyeing technology, and in particular to a protective component of a gas heating device for dyeing vats. Background Technology

[0002] As a traditional high-energy-consuming industry, the dyeing and printing industry faces enormous pressure to reduce carbon emissions. Most regions are promoting the use of clean energy, thus creating a significant need for upgrading and retrofitting production enterprises that rely on coal-fired boilers. Currently, to reduce energy loss and environmental pollution, gas-fired heating devices for dyeing vats are being used.

[0003] In the prior art, application number CN202411170850.6, patent title: Gas Heating Device for Dyeing and Printing Vat, the device should have the characteristics of small size, low energy consumption, and safety and reliability. The technical solution is a gas heating device for dyeing and printing vats, including a heat exchange unit and a combustion unit; the heat exchange unit has a first channel and a second channel arranged internally and externally, and several heat exchange tubes passing through both the first and second channels; one side of the heat exchange unit has a water inlet, and the other side has a water outlet, a flue gas inlet, and a flue gas outlet; the flue gas inlet, the first channel, the second channel, and the flue gas outlet are connected sequentially, and the flue gas flow directions of the first and second channels are opposite; the combustion unit is connected to the flue gas inlet; the water inlet, the heat exchange tubes, and the water outlet are connected sequentially. The outer shell of the main structure in this design lacks protection and insulation, which cannot guarantee safe use and makes it easy for heat exchange units to lose heat. In addition, if high-temperature flue gas leaks at the exhaust port, it will affect the normal operation of the combustion unit and the heat exchange unit. More importantly, the leaked high-temperature flue gas can easily burn workers, posing a certain danger.

[0004] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop protective components for the gas heating device of the dyeing vat. Utility Model Content

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, a further detailed description of this utility model will be provided below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] See Figures 1 to 3 As shown;

[0027] This embodiment discloses a protective component for a dyeing vat gas heating device, including a dyeing vat gas heating device body 1, which is the device body referred to in the background art. This protective component effectively protects against potential dangers faced by the dyeing vat gas heating device. The dyeing vat gas heating device body 1 has an outer shell 2 and an annular pipe 3. If the outer shell 2 is subjected to a violent impact, at best the structure will deform, causing changes in the internal flue structure and affecting heat exchange, or even the internal heat exchange tubes will deform, affecting the smooth flow of dye liquor and affecting heat exchange. In severe cases, the structure will break, leading to leakage of high-temperature flue gas or dye liquor, affecting normal heat exchange. Furthermore, the outer shell 2 has no insulation material, which will cause the high-temperature flue gas temperature to drop rapidly, resulting in heat loss. The annular pipe 3 is provided with a smoke exhaust port 4, which is a smoke exhaust channel structure with a vertical pipe and a flange interface. The connection between the smoke exhaust port 4 and the external pipe has a risk of leakage, and the high-temperature flue gas can easily burn the workers. Therefore, the outer shell 2 is provided with an insulation and protection structure to insulate and protect the outer side of the outer shell 2.

[0028] High-temperature flue gas shield structures are installed at four exhaust outlets to prevent high-temperature flue gas from leaking out at these outlets. A secondary exhaust pipe 5 is installed on the high-temperature flue gas shield structure, which is connected to the high-temperature flue gas shield structure for discharging the high-temperature flue gas inside. Firstly, the high-temperature flue gas shield structure covers the four exhaust outlets. If high-temperature flue gas leaks from these outlets, the shield structure immediately prevents the gas from overflowing. Simultaneously, the secondary exhaust pipe 5 discharges the leaked high-temperature flue gas to a safe location, preventing the gas from spreading and causing burns or other injuries to workers, thus ensuring the safe operation of the dyeing vat gas heating device.

[0029] Furthermore, the thermal insulation and protection structure includes two sets of annular sleeves 6 fitted onto the two ends of the outer shell 2. Multiple support rods 7 are connected between the two sets of annular sleeves 6. The multiple support rods 7 are arranged parallel to each other. The two sets of annular sleeves 6 are used to support the installation of the multiple support rods 7. The multiple support rods 7 are also used to position the two sets of annular sleeves 6. Thus, the multiple support rods 7 surround the outer shell 2 for protection. External impacts will impact the support rods 7 to avoid direct impact on the outer shell 2. In addition, depending on the specific use environment, the multiple support rods 7 can be directly replaced with a cylinder that fully encloses the outer shell 2 to provide all-round protection for the outer shell 2.

[0030] The outer shell 2 is covered with an insulation layer 8, which is located between the outer side of the outer shell 2 and multiple support rods 7. The multiple support rods 7 are used to press the insulation layer 8 tightly onto the outer surface of the outer shell 2 to maintain the stability of the insulation layer 8 wrapped around the outer side of the outer shell 2, and to prevent heat energy from being lost from the outer shell 2 quickly through the insulation layer 8.

[0031] Furthermore, the insulation layer 8 is made of ceramic fiber material, which has excellent thermal insulation and high-temperature resistance. It is not limited to ceramic fiber material; other insulation materials capable of withstanding temperatures up to 1000 degrees Celsius can replace the ceramic fiber insulation layer 8.

[0032] Furthermore, the high-temperature flue gas protective cover structure includes a protective box, which is divided into a left box 9 and a right box 10. The left box 9 and the right box 10 can be separated from each other. The left box 9 and the right box 10 are interlocked and fixed by bolts to form the protective box. During installation, the left box 9 and the right box 10 are respectively placed on both sides of the flue gas outlet 4 and connected to form the protective box. The protective box is then placed over the flue gas outlet 4 at a place where leakage is likely, such as the flange interface of the flue gas outlet 4. The left box 9 and the right box 10 of the protective box are then fastened together by bolts to form a seal. The sealing performance of the joint between the left box 9 and the right box 10 can be ensured by setting a sealing ring.

[0033] Both the upper and lower ends of the protective box are provided with clearance holes 11 to allow the smoke exhaust port 4 and the main smoke exhaust pipe connected to the smoke exhaust port 4 to pass through. The clearance holes 11 are formed at the position where the left box 9 and the right box 10 are interlocked so that the left box 9 and the right box 10 are interlocked to form a complete clearance hole 11. The clearance holes 11 are provided to ensure that the smoke exhaust port 4 and the main smoke exhaust pipe connected to it can pass through normally and be installed so as to realize the installation of the protective box.

[0034] The secondary exhaust pipe 5 is connected to the right-side box 10 so that the secondary exhaust pipe 5 is connected to the protective box, thereby enabling the high-temperature flue gas entering the protective box to be discharged in a timely manner through the secondary exhaust pipe 5.

[0035] Furthermore, a sealing ring 12 is provided inside the clearance hole 11. The sealing ring 12 includes two sets of semi-circular annular sealing bodies corresponding to the left box 9 and the right box 10 respectively. That is, a whole sealing ring is divided in half. When the left box 9 and the right box 10 are engaged, the two sets of semi-circular annular sealing bodies are connected to form the sealing ring 12, thereby forming a seal between the clearance hole 11 and the smoke outlet 4.

[0036] Furthermore, a temperature sensor 13 is installed inside the right-side housing 10 to measure temperature changes. If high-temperature flue gas leakage causes the internal temperature of the protective housing to rise, it can be used in conjunction with external warning devices, such as warning lights, to provide timely alarms and facilitate timely maintenance. The use of the temperature sensor 13 is common knowledge familiar to those skilled in the art and will not be elaborated further.

[0037] In the above technical solution, the protective component of the dyeing vat gas heating device provided by this utility model has the following beneficial effects:

[0038] The thermal insulation and protection structure of this utility model can effectively protect the outer shell of the main body of the dyeing vat gas heating device, preventing external impacts from affecting the stable internal operation. In addition, its thermal insulation function prevents heat loss from the heat exchange unit, ensuring heat exchange efficiency. It also provides effective protection against potential risks caused by high-temperature flue gas leakage at the exhaust port, making the dyeing vat gas heating device safer and more stable in operation.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
