Description

Heated air circulation oven

Technical Field

The utility model belongs to the technical field of the technique of medicine semi-manufactured goods drying equipment and specifically relates to a heated air circulation oven is related to.

Background

The hot air circulation oven is an oven with a circulating fan, and is mainly used for heating, curing, drying and dehydrating materials in the industries of medicine, chemical engineering and the like, such as the production of raw materials, traditional Chinese medicine decoction pieces, extractum, fans, particles, dehydrated vegetables and other products.

For example, chinese patent with publication number CN205607050U, filed 2016, 4, and 23, discloses a hot air circulation oven, which comprises a box body and a drying chamber arranged in the box body. The lower parts of the two side surfaces piled on the box body are respectively provided with an air inlet controlled by the temperature of the heating device, and the inner side of the air inlet is arranged on the side wall of the drying cavity. An air outlet controlled by an air draft device is arranged above the box body. A wind shield is arranged between the air outlet and the drying cavity, and an air channel is reserved between the wind shield and the inner wall of the drying cavity. The air outlet is communicated with the drying cavity through an air channel. The box body is provided with double-open box doors for opening and closing the box body, and the double-open box doors are connected through buckles. Four slide rails are arranged on the bottom wall of the drying cavity, and a slidable drying vehicle is arranged on each two slide rails. The cross section of the sliding rail is in a trapezoidal arrangement, and the width between the upper ends of the sliding rail is smaller than the width of the roller on the drying trolley. One side of each sliding rail, which is close to the box door, is provided with a sample loading port. One side that is close to the chamber door on the diapire of drying chamber articulates there is the baffle that separates, separates the rotation direction of baffle for being close to the chamber door to keeping away from the direction of chamber door. The sample loading openings are all located on the projection surface of the side, far away from the box door, of the bottom wall of the separation baffle plate projected to the drying cavity. The end part of the limiting block is provided with an elastic block made of elastic material. One side of the blocking plate close to the limiting block is provided with a groove matched with the limiting block.

When the device is used, the baffle plate is rotated to one side close to the oven door, the baffle plate and the ground form an inclined angle for the oven car to move, the oven car passes through the inclined baffle plate to the sample loading port and then enters the drying cavity through the slide rail, and the cross section of the slide rail is in a trapezoidal arrangement, and the width between the upper ends of the slide rail is smaller than the width of the roller on the oven car, so that the oven car is not easy to move laterally; after the drying trolley completely enters the drying cavity, the baffle plate is rotated to one side far away from the box door, the baffle plate and the limiting block are clamped to form a certain inclination angle, and the drying trolley is not easy to move outwards. After the material on the drying trolley is dried, the drying cavity is cooled firstly, after the cooling is finished, the box door is opened, then the baffle is rotated, so that the baffle and the ground form an inclination angle for the drying trolley to move, and then the drying trolley is pulled out from the drying cavity. In order to promote the work efficiency of dry material, it is bigger with the bigger of box setting usually, dry intracavity also can be bigger, dry intracavity can dry four drying cars to the material that can dry can be more.

After the four drying vehicles are dried and the drying cavity is cooled down, the two drying vehicles close to the box door are pulled out from the box door by a worker, and then the two drying vehicles far away from the box door are separated from each other. When the drying cart far away from one side of the oven door needs to be pulled out, workers need to enter the drying chamber, and the space in the drying chamber is narrow, so that the operation of the workers is inconvenient.

SUMMERY OF THE UTILITY MODEL

Not enough to above-mentioned prior art exists, the utility model aims at providing a heated air circulation oven then, be provided with the drive assembly who blocks the pole and drive and block the pole and slide through sliding to can make the staff drive through operation drive assembly and block the pole, thereby can take out the drying oven from the drying cavity, avoid the staff to need enter into to the drying cavity and pull out the drying oven, make things convenient for the staff to pull out from the drying cavity keeping away from imported and exported drying oven.

The above object of the present invention is achieved by the following technical solutions:

the utility model provides a heated air circulation oven, includes the box, set up the dry chamber that supplies the drying cart to place in the box, set up the exit that supplies the drying cart to get into on the box, be provided with on the box and be used for plugging up the chamber door of exit, it is provided with the barrier rod to slide along the direction that is close to or keeps away from exit in the dry chamber, be provided with on the box and be used for the drive assembly that the barrier rod slided.

Through adopting above-mentioned technical scheme, when needs put into the drying oven to the box, through drive assembly, the drive blocks the pole and slides towards the direction of keeping away from exit, until block the pole and slide to keeping away from the inner chamber wall department of exit near the drying chamber, then the staff promotes the drying oven and makes the drying oven enter into to the drying chamber, and make the drying oven contact with blocking the pole, then promote the drying oven with other drying oven and get into the drying chamber again, make the drying oven that gets into afterwards to paste with the drying oven that gets into before and lean on, close the chamber door at last. After the materials in the drying chamber are dried, the drying chamber is cooled firstly, then the drying vehicle close to the inlet and the outlet is pulled out from the drying chamber firstly by a worker, then the blocking rod is driven by the driving assembly to move towards the direction close to the inlet and the outlet, along with the movement of the blocking rod, the blocking rod drives the drying vehicle which is collided with the blocking rod to move downwards towards the direction of the door of the drying chamber until the drying vehicle moves to the inlet and the outlet, and then the worker pulls out the drying vehicle from the inlet and the outlet. Be provided with the drive assembly who blocks the pole and drive and block the pole and slide through sliding to can make the staff drive through operating drive assembly and block the pole, thereby can take out the drying trolley from the drying intracavity, avoid the staff to need enter into and pull out the drying trolley to the drying intracavity, make things convenient for the staff to pull out from the drying intracavity keeping away from the drying trolley of exit.
