Description

Technical Field

[0001] The utility model belongs to the technical field of oxygen-free copper rod production, and particularly relates to a drying device for oxygen-free copper rod production. Background Technique

[0002] An oxygen-free copper rod is pure copper that contains no oxygen and no residues of any deoxidizer. However, in fact, it still contains a very small amount of oxygen and some impurities. According to the standard regulations, the oxygen content is not more than 0.02%, the total impurity content is not more than 0.05%, and the purity of copper is greater than 99.95%.

[0003] Most drying devices for oxygen-free copper rod production have some disadvantages when in use. For example, before drying the oxygen-free copper rod, water droplets and dirt adhere to the surface of the oxygen-free copper rod, resulting in a reduction in the drying efficiency of the oxygen-free copper rod. At the same time, harmful gases are generated when the oxygen-free copper rod is dried, and the direct dispersion of the harmful gases to the outside may pollute the environment. In view of this, we propose a drying device for oxygen-free copper rod production. Content of the Utility Model

[0004] The purpose of the utility model is to provide a drying device for oxygen-free copper rod production to solve the problems raised in the above background technique.

[0007] A driving component, which is located on the drying shell and is used to drive the two rectangular frames to rotate;

[0008] A plurality of electric heating rods, all of the plurality of electric heating rods are fixedly installed in the other working cavity and are located below the rectangular frame. Ventilation shells are fixedly installed on the upper and lower sides of the drying shell and on the other working cavity. A fixing block is inserted and installed in the ventilation shell, an activated carbon filter screen is fixedly installed on the fixing block, and a negative pressure fan is fixedly installed on the top of the ventilation shell located above;

[0009] Two fixing components, which are respectively located in the two fixing blocks and are respectively used to fix the positions of the two fixing blocks.

[0010] In this technical solution, when the oxygen-free copper rod needs to be dried, first insert one end of the oxygen-free copper rod into one of the working chambers. Through the provided driving component, the two rectangular frames can be driven to rotate. The two rectangular frames respectively drive the four cleaning blocks to rotate. Then one end of the oxygen-free copper rod will enter between the two front cleaning blocks. The oxygen-free copper rod will squeeze the two front cleaning blocks to slide and move away from each other. The two front cleaning blocks respectively drive the corresponding two sliding plates to slide and move away from each other. At the same time, a number of corresponding first springs are compressed and contracted to ensure that the two cleaning blocks can always be in close contact with the oxygen-free copper rod. The two front cleaning blocks can wipe the dirt on the oxygen-free copper rod, and the two rear cleaning blocks can wipe the water droplets on the oxygen-free copper rod, so that there will be no more water droplets and dirt on the surface of the oxygen-free copper rod during drying, accelerating the drying speed;

[0011] Then the oxygen-free copper rod enters another working chamber. At this time, a number of electric heating rods will be powered on for heating, and at the same time, the negative pressure fan is started. The negative pressure fan will filter the outside air through the activated carbon filter screen at the bottom and then enter another working chamber. Subsequently, the air is heated by a number of electric heating rods and blown onto the oxygen-free copper rod to dry the oxygen-free copper rod and remove the moisture on the oxygen-free copper rod. Then the hot air and harmful gases generated by drying will be filtered by the activated carbon filter screen above to ensure that the harmful gases generated by drying will not pollute the environment;

[0012] When the activated carbon filter screen needs to be cleaned, through the provided fixing component, the operator can pull out the fixing block, and the fixing block drives the activated carbon filter screen to be taken out. When a new activated carbon filter screen needs to be installed, the operator inserts the fixing block into the corresponding ventilation shell. Through the provided fixing component, the position of the fixing block can be fixed, which is convenient for the operator to disassemble and install the activated carbon filter screen without using tools.

[0013] In the above technical solution, further, the driving component includes:

[0014] A motor, the motor is fixedly installed on the drying shell and is located on one side of one of the working chambers. The output shaft of the motor penetrates the drying shell and two fixing plates and two rotating grooves. On the output shaft of the motor and within the two rotating grooves, a first gear is fixedly installed respectively. The two first gears are respectively rotatably connected to the two rotating grooves;

[0015] Two second gears, the two second gears are respectively fixedly installed on one side of the two rectangular frames. The two second gears are respectively rotatably connected to the two rotating grooves. The two first gears are respectively located on one side of the two second gears, and the two first gears are respectively meshed with the two second gears.

[0016] In this technical solution, when the oxygen-free copper rod needs to be dried, first insert one end of the oxygen-free copper rod into one of the working cavities, and then start the motor. The motor is powered on and drives the two first gears to rotate. The two first gears respectively drive the two second gears meshing with them to rotate. The two second gears respectively drive the two rectangular frames to rotate. The two rectangular frames respectively drive the four cleaning blocks to rotate. Then one end of the oxygen-free copper rod will enter between the two front cleaning blocks. The oxygen-free copper rod will squeeze the two front cleaning blocks to slide and move away from each other. The two front cleaning blocks respectively drive the corresponding two sliding plates to slide and move away from each other. At the same time, the corresponding several first springs are compressed and contracted to ensure that the two cleaning blocks can always be in close contact with the oxygen-free copper rod. The two front cleaning blocks can wipe the dirt on the oxygen-free copper rod, and the two rear cleaning blocks can wipe the water droplets on the oxygen-free copper rod, so that there will be no more water droplets and dirt on the surface of the oxygen-free copper rod during drying, and the drying speed is accelerated.

[0017] In the above technical solution, further, the fixing component includes:

[0018] A sliding groove is opened in the fixed block. A limiting block is slidably installed in the sliding groove. One end of the limiting block penetrates through the sliding groove and is fixedly installed with several second springs fixed to the fixed block;

[0019] Two sliding rods are both slidably installed in the sliding groove and are located on both sides of the limiting block. The mutually close ends of the two sliding rods are both in contact with the limiting block. The mutually far ends of the two sliding rods both penetrate through the sliding groove and extend into the ventilation shell. The mutually far ends of the two sliding rods are both inserted and matched with the ventilation shell. A tension spring fixed to the sliding groove is fixedly installed on the mutually close sides of the two sliding rods.

[0020] In this technical solution, when the activated carbon filter needs to be cleaned, first pull the limiting block. At the same time, several second springs are compressed and contracted. At this time, the limiting block no longer presses the two sliding rods. Under the pulling force of the two tension springs, the two sliding rods slide and approach each other. When both sliding rods are separated from the corresponding ventilation shells, the staff can pull out the fixed block, and the fixed block drives the activated carbon filter to be taken out. When a new activated carbon filter needs to be installed, the staff inserts the fixed block into the corresponding ventilation shell, and then releases the limiting block. Under the rebounding force of several second springs, the limiting block slides. Then the limiting block presses the two sliding rods to slide and move away from each other. At the same time, the two tension springs are pulled and elongated. When both sliding rods are inserted into the corresponding ventilation shells, the position of the fixed block can be fixed, which is convenient for the staff to disassemble and install the activated carbon filter without using tools.

[0021] In the above technical solution, further, both sides of the limiting block are inclined.

[0022] In this technical solution, it is ensured that the limiting block squeezes the two sliding rods to slide and move away from each other.

[0023] In the above technical solution, further, several of the electric heating rods are distributed at equal intervals.

[0024] In this technical solution, it is ensured that the heating is uniform.

The oxygen-free copper rod will squeeze the two front cleaning blocks to slide and move away from each other. The two front cleaning blocks respectively drive the corresponding two sliding plates to slide and move away from each other. At the same time, the corresponding several first springs are compressed and contracted, ensuring that the two cleaning blocks can always be in close contact with the oxygen-free copper rod. The two front cleaning blocks can wipe the dirt on the oxygen-free copper rod, and the two rear cleaning blocks can wipe the water droplets on the oxygen-free copper rod, so that there will be no more water droplets and dirt on the surface of the oxygen-free copper rod during drying, accelerating the drying speed.

[0071] Among them, it is ensured that the output shaft of the motor 14 can rotate within the drying shell 1, the two fixing plates 3, and the two rotating grooves 4.

[0072] It is worth noting that: the two front cleaning blocks 8 use sponge blocks to ensure that the two front cleaning blocks 8 can wipe off the dirt on the oxygen-free copper rod, and the two rear cleaning blocks 8 use absorbent cloth to ensure that the two rear cleaning blocks 8 can wipe off the large water droplets on the oxygen-free copper rod.

[0073] Working principle: When it is necessary to dry the oxygen-free copper rod, first insert one end of the oxygen-free copper rod into one of the working chambers 2, and then start the motor 14. The motor 14 is powered on and drives the two first gears 15 to rotate. The two first gears 15 respectively drive the two second gears 16 meshing with them to rotate. The two second gears 16 respectively drive the two rectangular frames 5 to rotate. The two rectangular frames 5 respectively drive the four cleaning blocks 8 to rotate. Then one end of the oxygen-free copper rod will enter between the two front cleaning blocks 8. The oxygen-free copper rod will squeeze the two front cleaning blocks 8 to slide and move away from each other. The two front cleaning blocks 8 respectively drive the corresponding two sliding plates 6 to slide and move away from each other. At the same time, the corresponding several first springs 7 are squeezed and contracted to ensure that the two cleaning blocks 8 can always be in close contact with the oxygen-free copper rod.

[0075] When it is necessary to clean the activated carbon filter net 12, first pull the limit block 20. At the same time, several second springs 21 are squeezed and contracted. At this time, the limit block 20 no longer presses the two sliding rods 18. Under the pulling force of the two tension springs 19, the two sliding rods 18 slide and approach each other. When both of the two sliding rods 18 are disengaged from the corresponding ventilation cases 10, the staff can pull out the fixing block 11, and the fixing block 11 drives the activated carbon filter net 12 to be taken out. When it is necessary to install a new activated carbon filter net 12, the staff inserts the fixing block 11 into the corresponding ventilation case 10, and then releases the limit block 20. Under the action of the rebounding force of several second springs 21, the limit block 20 slides. Subsequently, the limit block 20 presses the two sliding rods 18 to slide and move away from each other. At the same time, the two tension springs 19 are pulled and elongated.
