Description

The present invention is an apparatus for making indoor heat treatment conditions uniform by moving up and down a blower for air circulation arranged in a room in an air conditioning room represented by a drying room and a freezing room.

Usually, the drying room requires high-temperature heat. In this case, the relationship between the temperature of the object to be dried and the temperature of the heat source is based on the relationship of air density (specific gravity). Stay. This causes a temperature difference between the upper part and the lower part of the room, and the heat treatment conditions vary depending on the part, resulting in unevenness of the material to be dried.

Moreover, in the indoor air circulation by the fixed air blower, the strength of the air volume received by the object to be dried is born. This causes non-uniformity of the object to be dried.

In order to process a large amount of dry matter at a time, the drying chamber has a large size and a large capacity, and the higher the indoor height, the more uneven the indoor temperature.

The method of indoor air circulation in a general drying room is that the blower that sends out air is fixed, so there is a difference in the drying time and the product to be dried at a place close to the wind sent by the blower and a place far away. As a result, it took a man-hour to change the position of the object to be dried in the room and to make the drying conditions uniform.

In an air-conditioned room represented by a drying room and a freezing room, the necessity of indoor air circulation is a factor that greatly affects the performance of the heat-treated product. The present invention is an apparatus in which an elevating function of a blower is constructed so as to provide uniform air circulation in the air-conditioned room.

The drying room plays a major role in moisture management in agricultural products, marine products, building materials and industrial products. Variations in the specifications of the dry-processed product and the product must be avoided, and the work of changing the arrangement of the product during the drying process affects the product price.

The present invention has been made based on such a background. The purpose of the present invention is to circulate air such as a difference in heat treatment products in an air-conditioned room space due to variations in temperature distribution, variations in the amount of air sent from a blower and received by a workpiece. It is an object of the present invention to provide a device for uniforming the heat treatment conditions in the air-conditioned room space.

In the air circulation raising and lowering apparatus in the air-conditioned room according to the present invention, the difference in the heat treatment product in the air-conditioned room is regarded as a phenomenon caused by non-uniformity of the circulating air. By moving the positional relationship with the workpiece to be processed back and forth while maintaining a certain distance from the bottom to the top, and continuously operating it, the room air is agitated, and uniform heat treatment conditions are maintained at any part of the top and bottom. It is an apparatus provided with feeding to a to-be-processed object.

The air circulation raising / lowering device repeatedly moves up and down while applying air to the object to be heat-treated with a blower. For the vertical movement of this blower, a general-purpose motor with a clutch brake and a speed reducer are combined to use an electric motor that is integrated with the switch. I do.

In order to match the processing conditions with the specifications required for the material to be heat-treated, this general-purpose electric motor is controlled by inverter control of the vertical movement speed of the blower, thereby making it possible to cope with it. Further, the rotational speed of the blower is also variable, and can be adjusted even when, for example, a breeze is an optimum processing condition for the object to be heat treated.

In addition to dealing with an increase in capacity in the air-conditioned room, the indoor arrangement of the blower is set to be opposed and the blower standby position is placed in an upside down position to increase the efficiency of indoor air circulation.

Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a front view and a side view of a room including a processing chamber to which the present invention is applied. The drive motor 1 is mounted outside the room, and an output shaft extends from the speed reducer. The output shaft is concentrically extended, and has a drive shaft 3 disposed in the upper part of the room. The rotation transmission with the drive motor is coupled by a coupling 2. Two sprockets 4 that transmit rotation are rationally arranged on the drive shaft 3, and bearings 7 that support rotation and load support are mounted on both sides of the sprocket to construct a drive system.

The blower 11 is fixed to the lifting frame 12. The up and down movement of the elevating frame 12 has a range of movement between the sprocket mounted on the drive shaft 3 in the upper portion and the sprocket 4 mounted on the driven shaft 13 in the lower portion. Also in the lower driven shaft 13, bearings 7 for rotation support are arranged on both sides of the sprocket.

The elevating frame 12 is located between the sprockets mounted on the drive shaft side and the driven shaft side, and one end portion of the chain 5 mounted on the sprocket 4 is coupled to the upper portion of the elevating frame 12 by a chain connection fitting 14. ing. The other side of the chain is connected to the lower part of the elevating frame 12 by a chain connection bracket 14 and connected to the lower surface of the balance weight 6 via a driven shaft side sprocket. In order to complete the chain connection, a chain connection fitting 14 is attached to the upper part of the balance weight 6 to connect the chain 5, and a connection wheel is formed by connection to the upper part of the lifting frame 12 via the drive shaft side sprocket 4.

The lifting weight with the blower 11 fixed to the lifting frame 12 reduces the load on the drive motor 1 by connecting the balance weight 6 in the chain wheel, thereby contributing to miniaturization of the motor output.

The bearing 7 that supports the rotation of the drive shaft 3 and the driven shaft 13 is fixed to the column 9 in order to ensure a required movement range of the blower 11 in the room. The support column 9 is fixed to a floor surface and an inner wall surface in order to perform a general load and a stable movement of the elevating frame 12 in the installation room. The fixing to the inner wall surface is connected by a mounting bracket 8. In the present embodiment, the required dimension of the mounting bracket 8 secures an installation space for the radiator 18 for the purpose of indoor heating between the support column 9 and the inner wall surface.

The elevating frame 12 in which the blower 11 is incorporated is connected to a guide rail unit 10 fixed to the support column 9 with a required length for stable movement. This guide rail unit is composed of a track rail and a slider having a bearing fitted to the track rail, and the track rail side is mounted on the support column 9 and the slider is mounted on the lifting frame 12 so that the swing of the lifting frame 12 can be smoothly moved. Is possible.

In order to repeatedly move the lifting frame 12 incorporating the blower 11, a bottom dead center limit switch 16 and a top dead center limit switch 15 are arranged on the support column 9 as electric signal sensor means, and the drive motor 1 is controlled by electric control. The raising / lowering frame 12 is repeatedly moved up and down by forward rotation and reverse rotation to enable continuous repeated operation.
