Description

Technical Field

[0001] This utility model relates to the field of hot-dip galvanizing furnace technology, specifically a preheating gas-fired hot-dip galvanizing furnace. Background Technology

[0002] Hot-dip galvanizing, also known as hot-dip zinc plating, is an effective method of metal corrosion protection. It is mainly used in metal structures in various industries. It involves immersing rust-removed steel parts in molten zinc at around 500°C, so that a zinc layer adheres to the surface of the steel parts, thereby achieving the purpose of corrosion protection.

[0003] For example, an existing Chinese patent (publication number: CN114703438A) discloses a preheating gas-fired hot-dip galvanizing furnace. The side of the heating furnace is fixedly connected to the side of the heating shell. A nozzle is provided on one side of the inner wall of the heating shell. The heating shell can store some hot gas, which can improve the heating efficiency to a certain extent.

[0004] However, the above-mentioned preheating side-heating gas-fired hot-dip galvanizing furnace has some drawbacks in use: the preheating side-heating gas-fired hot-dip galvanizing furnace is equipped with heating mechanisms on both sides of the furnace. Although both sides of the furnace can be heated simultaneously, improving the preheating of the molten zinc inside, the other sides of the furnace cannot be preheated, resulting in uneven heating inside the furnace and thus reducing the hot-dip galvanizing effect on the metal.

[0005] To address these issues, we designed a preheating gas-fired hot-dip galvanizing furnace. Utility Model Content

[0006] The purpose of this invention is to provide a preheating gas-fired hot-dip galvanizing furnace to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a preheating gas-fired hot-dip galvanizing furnace, including a hot-dip galvanizing tank containing molten zinc. A connector is fixedly installed at the bottom of one side of the hot-dip galvanizing tank. A rotating shaft is rotatably mounted at the bottom of the connector. A limiting component is fixedly installed at the bottom end of the rotating shaft. A connecting rod is fixedly installed at one end of the bottom of the limiting component. A heating component is provided at the other end of the connecting rod. The heating component abuts against the outer surface of the hot-dip galvanizing tank. A drive motor is fixedly installed at the top of the connector. The drive shaft of the drive motor is connected to the top end of the rotating shaft.

[0008] Furthermore, the heating assembly includes a heating cover, which is fixedly installed at the bottom end of a connecting rod. A gas cylinder is fixedly installed on one side of the connecting rod, and an ignition gun is provided on one side of the gas cylinder. A three-way pipe is provided at the other end of the ignition gun, and the other end of the three-way pipe is fixedly inserted into one side of the heating cover. A flame head is provided on the other side of the heating cover, and the flame head is fixedly connected to the three-way pipe.

[0009] Furthermore, a flame shield is fixedly installed at the end of the flame head away from the tee pipe, and the diameter of the flame shield is much larger than the diameter of the flame head.

[0010] Furthermore, the connecting rod is made of high-carbon steel.

[0011] Furthermore, a filter screen hopper is slidably inserted into the hot-dip galvanizing tank, and an L-shaped component is fixedly installed on the top of the filter screen hopper. The other end of the L-shaped component abuts against the top of the hot-dip galvanizing tank, and the filter screen hopper is completely immersed in the zinc liquid.

[0012] Furthermore, there are two L-shaped components, and the two L-shaped components are symmetrically fixedly installed on the top of the filter hopper.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By turning on the drive motor, the drive shaft of the drive motor can drive the rotating shaft to rotate, which in turn drives the limiting parts, connecting rods and even the heating components to rotate. This allows the heating components to move in an arc around the outer surface of the hot-dip galvanizing tank. Then, in conjunction with the heating components, flames can be sprayed onto the hot-dip galvanizing tank, achieving a uniform heating effect and improving the hot-dip galvanizing effect on metal parts.

[0015] 2. By placing the hot-dip galvanized metal into the filter hopper, the metal is immersed in the zinc liquid, which facilitates hot-dip galvanizing of the metal. By pulling the L-shaped part, the filter hopper can be slid out of the hot-dip galvanizing tank, which facilitates unloading the hot-dip galvanized metal. Attached Figure Description

[0021] Please see Figure 1-4 This utility model provides a preheating gas-fired hot-dip galvanizing furnace, including a hot-dip galvanizing tank 1 containing molten zinc. A connector 2 is fixedly installed on the bottom of one side of the hot-dip galvanizing tank 1. A rotating shaft 3 is rotatably installed on the bottom of the connector 2. A limiting member 4 is fixedly installed at the bottom end of the rotating shaft 3. A connecting rod 5 is fixedly installed at one end of the bottom of the limiting member 4. A heating component is installed at the other end of the connecting rod 5. The heating component abuts against the outer surface of the hot-dip galvanizing tank 1. A drive motor 6 is fixedly installed on the top of the connector 2. The drive shaft of the drive motor 6 is connected to the top end of the rotating shaft 3.

[0022] The heating assembly includes a heating cover 7, which is fixedly installed at the bottom of the connecting rod 5. A gas cylinder 8 is fixedly installed on one side of the connecting rod 5. An ignition gun 9 is provided on one side of the gas cylinder 8. A three-way pipe 10 is provided at the other end of the ignition gun 9. The other end of the three-way pipe 10 is fixedly inserted into one side of the heating cover 7. A flame head 11 is provided on the other side of the heating cover 7. The flame head 11 is fixedly connected to the three-way pipe 10.

[0023] In practice, turning on the drive motor 6 causes the drive shaft of the drive motor 6 to drive the rotating shaft 3 to rotate, which in turn causes the limiting part 4, the connecting rod 5, and even the heating cover 7 to rotate. This allows the heating cover 7 to move in an arc around the outer surface of the hot-dip galvanizing tank 1. Then, turning on the ignition gun 9 allows the three-way pipe 10 to spray the ignited flame onto the hot-dip galvanizing tank 1 through the flame nozzle 11 and the flame cover 12, achieving a uniform heating effect on the hot-dip galvanizing tank 1 and improving the hot-dip galvanizing effect on the metal parts.

[0024] See Figure 1-4 A flame shield 12 is fixedly installed at the end of the flame head 11 away from the tee pipe 10. The diameter of the flame shield 12 is much larger than the diameter of the flame head 11. This increases the size of the emitted flame, thereby further improving the preheating effect on the hot-dip galvanizing tank 1.

[0025] See Figure 1-4 The connecting rod 5 is made of high-carbon steel. High-carbon steel has high strength, which improves the tensile strength of the connecting rod 5.

[0026] See Figure 1-4A filter basket 13 is slidably inserted into the hot-dip galvanizing tank 1. An L-shaped part 14 is fixedly installed on the top of the filter basket 13. The other end of the L-shaped part 14 abuts against the top of the hot-dip galvanizing tank 1. The filter basket 13 is completely immersed in the zinc liquid.

[0027] In specific implementation, based on the above implementation, by putting the hot-dip galvanized metal into the filter hopper 13, the metal is immersed in the zinc liquid, which facilitates hot-dip galvanizing of the metal. By pulling the L-shaped part 14, the L-shaped part 14 can drive the filter hopper 13 to slide out of the hot-dip galvanizing tank 1, which facilitates unloading the hot-dip galvanized metal.

[0028] See Figure 1-4 There are two L-shaped parts 14, and the two L-shaped parts 14 are symmetrically fixedly installed on the top of the filter hopper 13. The two L-shaped parts 14 make it convenient for personnel to pull both ends of the filter hopper 13 at the same time, and can apply force better when personnel lift the filter hopper 13.

[0029] Before use, all electrical appliances involved in the hot-dip galvanizing furnace need to be connected to an external power source, or a battery pack needs to be installed in an area outside the connector 2 and heating cover 7 that does not obstruct other components. Then, the battery pack is connected to the electrical appliances through wiring. It is also necessary to avoid the wiring from getting tangled due to the movement of the components. Wiring needs to be buried and planned and organized to provide power to the electrical appliances, thereby ensuring the normal operation and switching of the electrical appliances. Since connecting the electrical appliances to an external power source or setting up a battery pack for power supply are existing technologies and are not problems that need to be solved in the background technology of this manual, they will not be explained in detail.

[0030] In use, first turn on the drive motor 6, which will cause the drive shaft of the drive motor 6 to drive the rotating shaft 3 to rotate. The rotating shaft 3 will then drive the limiting part 4, the connecting rod 5, and even the heating cover 7 to rotate. This will allow the heating cover 7 to move in an arc around the outer surface of the hot-dip galvanizing tank 1. Then turn on the ignition gun 9, which will allow the three-way pipe 10 to spray the ignited flame onto the hot-dip galvanizing tank 1 through the flame nozzle 11 and the flame cover 12. This will achieve the effect of uniform heating of the hot-dip galvanizing tank 1 and improve the effect of hot-dip galvanizing of metal parts.

[0031] By placing hot-dip galvanized metal into the filter hopper 13, the metal is immersed in the zinc liquid, which facilitates hot-dip galvanizing of the metal. By pulling the L-shaped part 14, the L-shaped part 14 can drive the filter hopper 13 to slide out of the hot-dip galvanizing tank 1, which facilitates unloading the hot-dip galvanized metal.
