Description

A drying equipment for Bondi tubes

technical field

The invention belongs to the technical field of drying equipment, and particularly relates to a drying equipment for Bondi tubes.

Background technique

Bondi tube refers to a thin steel pipe with a diameter of 4.6 to 10.6. Generally, its surface is plated with copper mold. It is mainly used as a fluid guide and air guide tube for automobiles and refrigerators. The manufacturing process of Bondi tube is slitting, pickling and drying. , cold-rolled coils, welding and copper plating, because after pickling, the steel strips need to be dried and dried to remove water stains on the surface, but the current drying equipment for Bondi tubes is still in use. A few shortcomings.

The current drying equipment for Bondi tubes is generally in the form of a drying box. The steel bars are passed through and dried by feeding rollers and receiving rollers. However, in the actual drying process, the acid on the steel bars There is a lot of liquid adhesion, and when the steel strip is transported out of the dryer, there will still be water traces on the surface; and when it is dried by hot air, when the temperature of the heating tube reaches the rated value, the heating tube will be turned off after being detected by the temperature sensor. However, the internal high temperature dissipates slowly, which greatly reduces the utilization rate of heat energy; and generally, the steel strip is in a relatively static state during transportation, and the water stains need to be volatilized at high temperatures, resulting in slower removal of water stains on the steel strip. It greatly prolongs the drying time, and so on, we still need to solve the problem.

Working principle: When the present invention is used, the user first installs the pickled steel bar on the left support plate 2 of the drying equipment through the feeding roller 3, and then mounts the steel bar on the cotton roller 7, the guide roller 11, the guide roller Roller 2, and wrap its head on the take-up roller 13, then turn on the power, set the working time for the first fan 16 and the spiral heating tube 17 through the timer 31, and start the first fan 16 and the spiral heating Pipe 17, and transfer the hot air flow to the drying channel 10 to provide drying temperature, then start the feeding motor 24, the wiping motor 32 and the receiving motor 26, the feeding motor 24 makes the feeding roller 3 rotate slowly under the action of the reducer, and When the steel strip passes through the cotton roller 7, the sliding block 5 moves along the thread groove under the unidirectional rotation of the wiping motor 32, so that the reciprocating movement can be realized, so that the cotton roller 7 also moves back and forth. Rolling under contact friction greatly increases the working area of the cotton roller 7 and improves its utilization efficiency. It does not need to be replaced regularly, which makes the staff overworked. Then, the steel bar with a small amount of water stains is blown by hot air in the drying channel, so that the water stains are evaporated and dried, and the vibration motor 25 can be started to drive the The cam rotates 23, and presses the elastic plate 22 up and down, and the guide roller 20 under the elastic plate 22 drives the steel bar to vibrate continuously, which can make the remaining water stains shake, increase the contact area between the water stains and the hot air, and improve the volatilization of the water stains. At the same time, the temperature sensor 12 monitors the internal temperature in real time. When the internal temperature reaches the rated value, it can be fed back to the controller 30. The controller 30 will turn off the spiral heating tube 17, and then start the production process. The second fan 19 in the air duct 18, the airflow will blow on the steel bar, and stick to the steel bar to push the internal hot air to continue to flow, and speed up the flow of the internal hot air, and is separated from the drying channel 10. The steel strip contacts again, which greatly improves the utilization efficiency of heat energy, and also avoids the temperature concentration and excessively high, which will affect the steel strip. Finally, the dried steel strip is wound on the take-up roller 13, and the whole working process ends.
