Description

  The present invention relates to an improvement of a dryer for drying a material to be dried such as a powder material in a container.

  2. Description of the Related Art Conventionally, there is known a drying apparatus that mixes a material to be dried such as a powder material in a container and feeds the warm air into the container to perform a drying process (see the following patent document).

Japanese Patent No. 3734985

  The drying device described in the above-mentioned patent document rotates the rotating drum in a state inclined at a predetermined angle, supplies hot air from the hot air supply port, and forces the hot air from the hot air exhaust port. Exhaust. As a result, the object to be dried accommodated in the rotating drum is blown away in the axial direction (length direction) of the rotating drum by the hot air, and is wound from the outside to the inside by the rotating motion of the rotating drum. Since it is uniformly in contact with the warm air, there is an advantage that a large amount of processed material can be dried with a relatively small amount of warm air.

  However, the drying apparatus having the above-described configuration can dry the object to be dried in contact with warm air evenly, but the rotating drum that accommodates the object to be dried tilts and rotates it. There is a problem that the apparatus becomes complicated and large.

  In addition, when discharging the object to be dried from the rotating drum, the object to be dried in the rotating drum is rotated by rotating the rotating drum with the warm air exhaust port inclined obliquely at a predetermined angle. A thing needs to be discharged from the hot air outlet, and a complicated operation is required.

  In view of the above problems, the present invention is an improved drying method that can simplify the operation of discharging the object to be dried from the container while keeping the drying capability of the object to be dried while simplifying the configuration of the apparatus as much as possible. The purpose is to provide a machine.

  The invention according to claim 1 is a container for storing an object to be dried such as a powder material, a supporting means for mounting the container, and a rotating means for rotating the container within a predetermined angle range with respect to the supporting means. The drying apparatus is characterized in that an intake means is provided on one of the rotating shafts constituting the rotating means, and an exhaust means is provided on the other rotating shaft constituting the rotating means.

  According to a second aspect of the present invention, the intake means of the first aspect of the invention is configured to rotate together with the container by inserting the rotary shaft rotatably supported by the support means and one end of the rotary shaft into the container. The container outside and the container communicate with each other through a flow path formed in the hollow portion of the rotating shaft, and the object to be dried in the container rotates at one end of the rotating shaft inserted into the container. It is characterized by comprising a filter that prevents leakage from the shaft channel to the outside of the container.

  According to a third aspect of the present invention, the exhaust means of the first aspect of the present invention is the same as the exhaust shaft of the first aspect of the invention, and a rotating shaft that is rotatably supported by the supporting means, and one end of the rotating shaft is inserted into the container. It is configured to rotate and communicates between the outside of the container and the inside of the container through a flow path formed in the hollow portion of the rotating shaft, and an object to be dried in the container is attached to one end of the rotating shaft inserted into the container. It is characterized by comprising a filter that prevents leakage from the flow path of the rotating shaft to the outside of the container, and a cover body that prevents the material to be dried from depositing around the filter.

  According to the first aspect of the present invention, the entire apparatus can be uniformly dried with a simple apparatus configuration while sufficiently expanding the rotation angle range of the container and sufficiently mixing the object to be dried by only the rotation operation. Is possible.

  According to the second aspect of the present invention, since the intake means is configured using the rotation shaft necessary for the rotation operation of the container, it is not necessary to provide the intake means separately from the rotation shaft, and the apparatus configuration can be further simplified. .

  According to the third aspect of the present invention, since the exhaust means is configured using the rotation shaft necessary for the rotation operation of the container, it is not necessary to provide the exhaust means separately from the rotation shaft, and the apparatus configuration can be simplified. Since the cover body is provided around the filter provided in the exhaust means, it is possible to prevent the material to be dried from being deposited around the filter of the exhaust means and reducing the exhaust efficiency.

It is a longitudinal cross-sectional view which expands and shows the suction means of the dryer of this invention. It is a longitudinal cross-sectional view which expands and shows the exhaust means of the dryer of this invention. It is a side view when rotating the dryer of this invention.

  Embodiments of the present invention will be described below with reference to FIGS. In FIG. 1, A shows a dryer according to the present invention, and 1 is a container (hereinafter referred to as a rotating drum) for storing a material to be dried such as a powder material, and one end in the longitudinal direction (FIG. 1). (To the upper side) is provided with an inlet / outlet 2 for a processed material (not shown).

  Reference numeral 3 denotes a support base formed by a frame made of angle steel or the like, and supports the rotating drum 1 via rotating shafts 6 and 7 rotatably supported on support seats 4 and 5 by bearings (not shown).

  Reference numeral 8 denotes a sprocket fixed to the rotary shaft 6, which rotates by receiving a rotational output of an electric motor 9 (geared motor or the like) installed at a lower portion of the support base 3 by a belt 10.

  FIG. 2 shows an intake means 11 which is one of the main parts of the present invention. The suction means 11 is configured by using the rotating shaft 7, and the hollow cylindrical rotating shaft 7 is inserted into the hollow portion 12 of the support seat 5 constituting the support base 3, and one end ( The outer peripheral portion at the left end in FIG. 2 is pivotally supported by the support seat 5 via a bearing 13. A hollow nozzle 15 is attached to the opening 14 at the left end of the rotary shaft 7, and hot air from a hot air generator composed of a heater and a blower as a heat source (not shown) is passed through the flow path of the rotary shaft 7. It is comprised so that it may feed in 16.

  The other end (the right end in FIG. 2) of the rotating shaft 7 is immersed and fixed in the rotating drum 1, and an unshown object to be dried in the rotating drum 1 is placed in the opening 17 of the rotating shaft 7. A filter 18 that prevents leakage to the outside of the rotating drum 1 through the flow path 16 is fixed.

  FIG. 3 shows an exhaust means 19 which is another main part of the present invention. The exhaust means 19 is configured by using the rotary shaft 6, and the hollow cylindrical rotary shaft 6 is inserted into the hollow portion 20 of the support seat 4 constituting the support base 3, and one end ( The outer periphery of the right end in FIG. 3 is pivotally supported by the support seat 4. A sprocket 8 is attached to the outer periphery of the right end of the rotating shaft 6 so as to rotate together with the rotating shaft 6.

  The other end (left end in FIG. 3) of the rotating shaft 6 is immersed and fixed in the rotating drum 1, and an unillustrated object to be dried in the rotating drum 1 is placed in the opening 21 of the rotating shaft 6. A filter 23 is secured to prevent leakage to the outside of the rotating drum 1 through the flow path 22.

  Also, a cover body 24 is attached to the left end of the rotating shaft 6 to prevent unprocessed material to be dried in the rotating drum 1 from accumulating around the filter 23 and hindering exhaust. In addition, the right end of the rotating shaft 6 is connected to a hot air discharge device such as a wind exhauster (not shown).

  Next, the case where the drying object is dried in the dryer A will be described. When drying an object to be dried, such as a powder material, after the rotary drum 1 is tilted so that the inlet / outlet port 2 is obliquely upward from the vertically upward state, the object to be dried is charged / discharged. It is put into the rotary drum 1 from the outlet 2.

  When the input of the material to be dried is completed, the input / discharge port 2 is closed with a lid (not shown), and the motor 9 of the dryer A shown in FIG. 1 is driven to rotate the sprocket 8 via the belt 10. The rotation of the sprocket 8 is transmitted to the rotation shaft 6, and the rotation shaft 6 rotates using a bearing (not shown) provided in the support seat 4 of the support base 3.

  The rotary shaft 6 is connected to the rotary drum 1, and the rotary drum 1 is rotated by using the bearing 13 shown in FIG. 2 of the support seat 5 constituting the support base 3 by the other rotary shaft 7. The rotary drum 1 connected to the rotary shafts 6 and 7 rotates as shown in FIG.

  The rotation of the rotary drum 1 is realized by driving and controlling the electric motor 9 with a control program set in advance in a control device (not shown). It is set to an optimum value according to the type of the dried processed product and the input amount. In this embodiment, a case where the rotation angle range of the rotary drum 1 is set to a range of about 180 degrees shown in FIG. 4 will be described.

  When the rotating drum 1 rotates, hot air supplied from a hot air generator (not shown) is sent into the flow path 16 of the rotating shaft 7 through a nozzle 15 attached to the rotating shaft 7 shown in FIG.

  The warm air sent in is supplied into the rotary drum 1 through a filter 18 attached to the right end of the rotary shaft 7, comes into contact with the object to be dried in the rotary drum 1, and is dried. At this time, since the rotating drum 1 rotates in a wide angle range as described above, the dry matter to be dried in the rotating drum 1 is sprayed with warm air while being sufficiently mixed by the rotating operation of the rotating drum 1. As a result, the entire object to be dried comes into contact with warm air uniformly, and the drying efficiency can be improved.

  The hot air dampened by coming into contact with the object to be dried passes through the flow path 22 in the rotary shaft 6 from the filter 23 by the suction force of a wind exhauster (not shown) attached to the exhaust means 19 shown in FIG. It is discharged outside the rotary shaft 6.

  At this time, since the cover body 24 surrounding the filter 23 of the rotary shaft 6 is attached, the processed material does not accumulate around the filter 23 even by the rotating operation of the rotary drum 1. Exhaust through the filter 23 is not hindered. Further, the material to be dried in the rotary drum 1 is not leaked out of the rotary drum 1 by the filters 18 and 23 of the intake means 11 and the exhaust means 19.

  On the other hand, by repeating the above-described exhausting operation, an object to be dried made of a powder material or the like may adhere to the filter 23 of the exhausting unit 19 and clogging may occur. In this case, air is exhausted. What is necessary is just to eliminate clogging using backwashing sprayed from the right end side (exhaust fan side not shown) to the left end side (rotating drum 1 side) or vibration by a vibrator.

  When the object to be dried is sufficiently dried as described above, the driving of the electric motor 9 is stopped to end the rotation operation of the rotary drum 1, and the hot air generator and the hot air discharge device (not shown) are stopped. Thereafter, a lid (not shown) of the charging / discharging port 2 is opened, the rotary drum 1 is rotated in a vertically downward state, and the material to be dried is taken out from the charging / discharging port 2 to dry the processing material to be dried. Exit.

  As described above, according to the dryer A of the present invention, the rotary drum 1 can be rotated in a wide angle range, so that the material to be dried can be sufficiently mixed only by the rotating operation, as in the conventional case. In addition, the entire object to be dried can be uniformly dried without providing a complicated structure for realizing both the tilting and rotating operation of the rotating drum.

  Further, since the warm air for drying the object to be dried can be sucked and exhausted by using the rotary shafts 6 and 7, it is not necessary to provide a separate mechanism for realizing intake and exhaust, and the apparatus structure is simplified. Can do.

  Note that the wind speed of the warm air fed into the rotary drum 1 can be adjusted according to the size of the diameter (pipe diameter) of the flow path 16 of the rotary shaft 7 constituting the intake means 11. Even if the amount of warm air sent out from a hot air generator (not shown) connected to the intake means 11 is constant, for example, by increasing the diameter of the flow path 16, the speed of the warm air can be reduced, and conversely the diameter can be reduced. By making it small, the wind speed of the warm air can be increased. Therefore, it is possible to variously change the wind speed of the warm air according to the characteristics of the object to be dried.

  The present invention can be applied to any apparatus that performs a drying process on an object to be dried in a container.
