Description

Heated air circulation drying cabinet

Technical Field

The utility model relates to a drying cabinet technical field, concretely relates to heated air circulation drying cabinet.

Background

Red copper is also known as pure copper. The melting point is 1083 ℃, the conductive coating has good electrical conductivity and thermal conductivity, the plasticity is excellent, the hot-pressing and cold-pressing processing is easy, and the conductive coating is widely used for manufacturing products which require good electrical conductivity, such as wires, cables, electric brushes, special electric spark erosion copper and the like.

Before the copper block is processed and produced, in order to ensure the production quality, the copper block is soaked in a rust removing agent to remove the copper rust on the copper block. After the copper block is soaked in the rust removal agent, in order to prevent moisture in the agent from adhering to the copper block to cause secondary oxidation of the copper block, the copper block after rust removal can be placed into a drying box to be dried, and the moisture on the copper block is removed. In the prior art, when copper blocks are dried, the copper blocks are generally stacked in a drying oven, a door of the drying oven is closed, and then drying is started. However, when the copper blocks are dried by adopting the method, the following defects exist, the copper blocks at the centers of the stacked copper blocks cannot be directly contacted with warm air in the drying process, so that water adhered to the copper blocks at the positions is difficult to be quickly dried; and secondly, the drying oven needs to be operated for a long time for ensuring that all copper blocks can be dried, so that the electric energy consumed by drying is increased, and the drying cost is increased. Therefore, a drying oven capable of rapidly drying the copper blocks is needed.

In order to solve the technical problem, the utility model provides a following technical scheme: a hot air circulation drying box comprises a box body and a rotating mechanism, wherein a box door is hinged on the box body, a fan with an upward air outlet is arranged at the bottom of the box body, an electric heating net is arranged in the box body and positioned above the fan, a vent pipe is communicated with the top of the box body, the bottom end of the vent pipe is communicated with an air suction pump, and the air outlet of the air suction pump is communicated with the bottom of the box body; the rotating mechanism comprises a motor fixed to the top in the box body, an output shaft of the motor is vertically downward, a tray is fixedly connected to the bottom end of the output shaft of the motor, the circumference of the tray is in clearance fit with the inner wall of the box body, a spiral plate is arranged on the output shaft of the motor, the bottom end of the spiral plate is tangent to the upper surface of the tray, and a plurality of vent holes are uniformly distributed in the spiral plate and the tray.

The utility model discloses the theory of operation: during the use, put into the box through the copper billet that the chamber door will be dried, start the fan, the electric heat net, motor and aspiration pump, the air that blows during the fan operation flows upwards, the air flows upwards through the electric heat net, the electric heat net heats the air and makes the air be heated and become hot-air, because be equipped with a plurality of air vents on tray and the spiral plate, consequently, hot-air dries the copper billet on the tray after passing through the air vent, and the motor drives tray and spiral plate rotation during operation, because the bottom of spiral plate is tangent with the tray, the copper billet on the tray upwards slides along the spiral plate under inertial effect when tray and spiral plate rotate, drop on the tray from the spiral plate when the copper billet slides the top of spiral plate. When the air pump operates, air at the top of the box body is pumped into the vent pipe, hot air in the vent pipe is blown into the bottom of the box body by the air pump along the vent pipe, and is blown to the electric heating net by the fan again.

The utility model has the advantages that: this scheme passes through the motor and drives the spiral plate and the tray rotates for the copper billet constantly slides the top of spiral plate along the spiral plate under inertial effect on the tray, then falls to the tray from the top of spiral plate again on, so remove the copper billet repeatedly and make every copper billet can both be abundant with hot-blast even contact, consequently accelerated the stoving speed to the copper billet, improved drying efficiency. 2. The lower air of box top temperature is taken out through setting up breather pipe and the aspiration pump at the box top, lets in this part air bottom half again, blows the air to the electric heat net once more through the fan, carries out cyclic utilization to hot-blast, reduces the energy resource consumption of electric heat net when to air heating, improves thermal utilization ratio in the air simultaneously.

Further, the top of box is equipped with the feed inlet, and the intercommunication has feed hopper in the feed inlet. The purpose is to add copper blocks into the box body conveniently through the arrangement.

Furthermore, one end of the vent pipe close to the top of the box body is fixedly connected with a sponge, and the sponge is positioned in the vent pipe. The purpose is that the sponge is arranged in the vent pipe to suck out the moisture in the hot air flowing from the vent pipe through the water absorption characteristic of the sponge.

Furthermore, a drain hole is formed in the vent pipe and located right below the sponge, and a water accumulating bottle is communicated with the drain hole. The purpose is that when the moisture in the sponge is excessive, the moisture gradually moves downwards under the action of gravity and falls into the water accumulating bottle through the drain hole.

Further, the upper surface of the spiral plate is fixedly connected with a cross rod, and the cross section of the cross rod is arc-shaped. Its purpose makes the copper billet appear stirring when sliding on the spiral plate through this kind of setting for it is more even to the stoving of copper billet.

Furthermore, a heat-insulating layer is sleeved outside the vent pipe. Its purpose is, avoids the hot air heat in the breather pipe to run off.
