[0002] Automobile brake pipes are key components of automobile brake systems. During the processing, the original steel pipe surface is coated and then needs to be dried. The commonly used processing method is generally to use a fan to blow heated air into a drying box to dry the product. The dried gas diffuses into the air in large quantities, causing environmental pollution.

[0003] In order to avoid the dried gas from polluting the environment, the dried gas is often filtered before being discharged. However, since the dried gas still has a certain amount of heat, if it is directly discharged after filtering, it will cause energy waste and is not conducive to economic efficiency.

[0004] In order to ensure the economy of the operation process, we urgently need a galvanizing drying circulation device. Utility Model Content

[0025] It should be noted that the galvanized drying circulation device described in the present invention is used for but not limited to automobile parts processing, etc. For the convenience of explanation, in the present invention, only a galvanized drying circulation device applied to automobile parts processing is used as an example for explanation. The principle of applying a galvanized drying circulation device to other types of equipment is essentially the same as the principle applied to automobile parts processing, so they will not be described one by one here.

[0026] See also Figure 1 - Figure 4 ,in, Figure 1 This is a structural schematic diagram of a galvanized drying circulation device in one embodiment of the present invention, which includes a frame 100, a drying box 200, a circulation pipe 300, a heater 400 and a fan 500. The drying box 200 is fixedly installed on the top of the frame 100, the circulation pipe 300 is arranged in the frame 100 and connected to the bottom of the drying box 200, the circulation pipe 300 is used to circulate air, the heater 400 is arranged on the circulation pipe 300, and the fan 500 is connected to the circulation pipe 300;

[0027] In this embodiment, the fan 500 is started, and the fan 500 pumps external air into the circulation pipe 300. The air enters the drying box 200 after being heated by the heater 400. At the same time, the galvanized pipe is extended into the drying box 200 from one side thereof, and the hot air heats and passivates the galvanized pipe. At this time, the circulation pipe 300 draws in and circulates the air on the other side of the drying box 200. This part of the air passes through the heater 400 and re-enters the drying box 200, thereby continuously circulating and continuously passivating. By recycling the dried air, this device reduces the impact of such dried air on the environment and does not need to reheat the air at normal temperature, thereby ensuring the economy of the operation.

[0028] In one embodiment, see Figure 1 - Figure 3 The drying box 200 is in the shape of a rectangular parallelepiped, and a plurality of material holes 210 are opened on both ends of the drying box 200. A drying pipe 220 is provided in the middle of the drying box 200. The drying pipe 220 is in the shape of a frame, and a plurality of air nozzles 230 are penetrated from one end to the other end of the drying pipe 220. Two groups of material holes 210 are respectively arranged coaxially with the air nozzles 230. The circulation pipe 300 is connected to the bottom of the drying box 200. The inner wall of the air nozzle 230 is provided with a sliding sleeve 231. Both sides of the bottom of the drying pipe 220 are fixedly connected to support rods 221, and the bottoms of the two support rods 221 are fixedly connected to the bottom of the drying box 200. A feeding rack 240 is provided on one side of the drying box 200, and feeding rollers 241 are arranged on the feeding rack 240 opposite to each other. The symmetrical midlines of the two feeding rollers 241 are in the same horizontal plane as the axis of the air nozzle 230.

[0029] In this embodiment, the galvanized pipe fittings enter the drying box 200 through a plurality of material holes 210 on one end thereof, and the galvanized pipe fittings enter the drying pipe 220 through the air nozzle 230 at this end, thereby passing through the plurality of air nozzles 230 to complete the drying and passivation.

[0030] The sliding sleeve 231 in the air nozzle 230 is made of ceramic material, which greatly reduces friction.

[0031] In one embodiment, see Figure 1 - Figure 2The circulation pipe 300 includes an air inlet pipe 310, a suction pipe 320 and a connecting pipe 330. The air inlet pipe 310 is provided on one side of the bottom of the drying box 200. The top end of the air inlet pipe 310 passes through the drying box 200 and is connected to the drying duct 220. The bottom end of the air inlet pipe 310 is connected to one end of the heater 400. The suction pipe 320 is provided on the other side of the bottom of the drying box 200. The top end of the suction pipe 320 is connected to the bottom of the drying box 200. The bottom end of the suction pipe 320 is connected to the fan 500. The end of the connecting pipe 330 away from the heater 400 is connected to the fan 500. The middle part of the suction pipe 320 is connected to the air supply pipe 321, and the air supply pipe 321 is provided with a valve 322.

[0032] In this embodiment, the fan 500 is started, and the fan 500 takes in air through the air supply pipe 321 on the suction pipe 320, and pumps it into the heater 400 until it enters the drying pipe 220 in the drying box 200. As the galvanized pipe fittings are moved, the dry air will overflow into the drying box 200 through the air nozzle 230. At this time, the suction pipe 320 sucks in this part of the air and re-enters the heater 400, and the cycle continues.

[0033] In one embodiment, see Figure 2 , a flow monitor 600 is provided between the connecting pipe 330 and the heater 400;

[0034] In this embodiment, the flow monitor 600 can monitor the air flow. When the air flow drops below a standard value, the valve 322 on the air supply pipe 321 can be opened to allow rapid air supply.

[0035] In one embodiment, see Figure 1 , the top of the drying box 200 is provided with a split box cover 700;

[0036] In this embodiment, the split box cover 700 is convenient for opening the cover to observe the internal processing conditions, and can also prevent the internal air from overflowing over a large area when the cover is opened.

[0037] In one embodiment, see Figure 1 The bottom of the frame 100 is provided with a shock-absorbing foot 800.

[0038] In order to better understand the present invention, the following Figures 1 to 4The technical solution of the present invention is described in detail: start the fan 500, the fan 500 takes in air through the air supply pipe 321 on the suction pipe 320, and pumps it into the heater 400 until it enters the drying pipe 220 in the drying box 200. At this time, the galvanized pipe fittings enter the interior of the drying box 200 through the several material holes 210 on one end side, and the galvanized pipe fittings at this end enter the drying pipe 220 through the air nozzle 230, thereby passing through the several air nozzles 230 to complete the drying passivation. As the galvanized pipe fittings move, the dry air will overflow into the drying box 200 through the air nozzle 230. At the same time, the suction pipe 320 sucks in this part of the air and re-enters the heater 400, and the cycle is repeated, so as to continuously circulate and continuously passivate. This device reduces the impact of such dry air on the environment by recycling the dried air, and does not need to reheat the normal temperature air, thereby ensuring the economy of the operation.

[0039] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention.
