Conventional Haitai drying apparatus is simply in the processing chamber into which one type of hot air is blown, Haitai Bal (海 笞) Since the drying process was carried out by hot air of the same temperature by passing it on a conveyor, it did not adapt to the drying characteristics of Haitai, but rather caused the degradation of Haitai produced by drying. In order to adapt to the drying characteristics of Haitai, the primary treatment by constant temperature drying is carried out using relatively high temperature hot air for the drying process in the treatment chamber, followed by a relatively low temperature hot air. To the secondary treatment by the reduction ratio drying, and if necessary, the secondary treatment is continued to the secondary treatment, and then the return treatment is performed by using outside air to remove the damage caused by overdrying of the tai chi. Always ensure that the hot air for the treatment of temperature, humidity and wind speed for each treatment condition is used effectively. It is easy to form a device for obtaining hot air for processing that differs in terms of conditions, and a passage for appropriately acting these hot air for the haebata moving in the treatment chamber, thereby obtaining a high quality dry product and operating cost economically. An object of obtaining an apparatus, specific embodiments of the embodiments will be described with reference to the drawings.

The drying apparatus of the present invention, as shown in Figs. 1 and 6, has a hot air treatment for disposing a hot air blowout duct and a suction duct therein and moving the conveyor for maintaining the sea paw according to this arrangement. And a hot air exhaust box (12) having a heating device therein partitioning a passage for supplying and exhausting the hot air to the blowout duct and the suction duct in the processing chamber (12). It is composed of a combination of three enclosures (1), (11), (12) of the (), characterized in that the enclosures (1), (11), (12) can be assembled and disassembled at any time.

The hot air treatment chamber 1 is alternately formed with suction ducts 3a, 3b, and 3c and blowout ducts 2a and 2b at the front of the interior as shown in FIG. A flat plate-shaped blowout duct 4 and a suction duct 5 are disposed to face each other in a vertical direction along the lower surface of the direction, and the treatment hot air is blown out through the blowout ducts 2a, 2b, and 4. On the opposite surface of each duct to intake air into the ducts 3a, 3b, 3c, and 5, slits are provided or a punching plate having a plurality of small holes is formed, and the upper extraction duct 2a, By attaching the taper so that the upper light lower blowout duct 4 of (2b) is narrowed in the direction in which the wind blows, a blowout hot air of a uniform wind speed distribution is obtained. In the illustrated example, the upper extraction ducts 2a, 2b and the suction duct 3b are formed in an arc shape so as to conform to the circulating passage of the hataetae conveying conveyor 6 as described later. Except the suction duct 3C, each of the other blow-out suction ducts communicates with the air passages formed in the hot air generating 11 and the hot air exhaust box 12 directly or through a connection pipe, thereby forming a hot air circulation circuit. The suction duct 3C at the rear end communicates with the exhaust pipe 15.

In the hot air treatment chamber 1, the front entrance (7) is arranged so as to traverse the opposing intervals of the upper and lower ducts (2) and (3) and the opposing intervals of the lower flat plate and the ducts (4) and (5). Into the hot air treatment chamber (1), the construction of the Haitai bal conveying conveyor (6) mainly composed of the chain that is evicted from the exit (8) to the endless run, and to maintain the Haitai bal here at the inlet (7) and exit In (8) this is taken out, but the detailed description is abbreviate | omitted.

Therefore, the conveyor 6 holding the Haitai foot is meandered from the top to the top in the hot air treatment chamber 1, and then shifts to the horizontal state at the bottom, and moves away from the outside. Perform the first process by drying the frame with the period from point A to the room B as electricity, and from the point C to the second treatment section by bobbin drying, and again from the point C Up to point D of 8) was subjected to the return process by outside air to avoid the damage of excess drying by hot air. For this reason, the rear blowout duct 2b in the processing chamber 1 is divided into two chambers 2c and 2d before and after by the diaphragm, and the first half 2c is used as the primary treatment duct, and the latter half ( 2d) is a secondary processing duct, and the air intake fan 4a is partitioned by a diaphragm 4b at the front end of the lower plate-shaped blowout duct 4, and the intake fan 16 mounted on the front surface thereof. By returning the outside air directly into the duct 4a and taking them out on the screen, the secondary processing section B to C in the drawing is the secondary processing section and the C to D point is the return processing section by the outside air. Formed.

The hot air generation 11 is provided with an outside air inlet 17 having an opening / closing control lid on the upper surface as shown in FIG. 4 and surrounding the blower 9 and its blowout port downwards. If the heating furnace 10 is provided in the heating chamber 11a formed above, the outside air introduced into the blower chamber 9a from the outside air inlet 17 and returning hot air which will be described later are added to the heating furnace 10 and here. Heated by heat dissipation of the communicating heating tube 10a, and a part of the front blowout duct 2a in the processing chamber 1 is transferred to the upper air vent 18 of the heating chamber 11a as hot air at an appropriate temperature. ) To be sent.

In addition, the furnace chamber 11a is partitioned into partition walls, and the outside air inlet 17 is introduced into the outside air inlet. The outside air is heated in advance by contact with the partition walls, and in particular, the furnace chamber 11a. ) Can be considered as a heat insulating structure, so that the heat efficiency due to preheating is increased and the production of the furnace chamber 11a is simplified. The hot air exhaust box 12 may be formed integrally or separately from the hot air generation box 11 as shown in FIGS. 3 and 5 to be separated together with the hot air generation 11 on one side of the processing chamber 1. And a supply passage 13a for sending a part of the hot air sent out from the furnace chamber 11a to the first half portion 2c of the upper blowout duct 2b in the processing chamber 1 via the air vent 19; In the blower chamber 11 where hot air is generated in the vents 20, 21, and 26 by return air from the upper suction ducts 3a, 3b and the lower suction duct 5 in the processing chamber 1; A part of the return passages 13 and 13d of the return air passages to the return air passages 13b, 13c, and 13d are introduced into the communication port 22, and the outside air inlet 25 The low-temperature hot air mixed with the outside air introduced in the air) is blown by the air blower 27 through the air vents 23 and 24 to the second half 2d of the upper blowout duct 2b in the processing chamber 1 and the lower blowout duct ( A low temperature hot air supply passage 14 for secondary treatment, which is a supply passage 14a or 14b for sending air to 4), is provided.

In this way, the above-mentioned hot air generating box 11 and the hot air exhaust box 12 are connected to one side of the processing chamber 1, so that the blowout ducts 2a, 2c, 2d, and 4 in the processing chamber 1 are connected. The hot air at an appropriate temperature is supplied to the heat exchanger, and the return hot air from the suction ducts 3a, 3b, and 5 is returned to the heating chamber 11a via the heat transfer chamber 9a, and this is reprocessed again. Circulate). In addition, the lower suction duct 5 opens one side to the atmosphere by the opening 28, and about half of the return hot air is discharged from the opening 28 to the outside, while the other half is the other air vent 26 on the other side. Return to the blower chamber 9a from the aeration passage 13d joining the aeration passage 13c via (9), and recover the heat, and the front end of the lower plate-shaped suction duct 5 is taken out of the outside air duct. Corresponding to (4a), the exhaust duct 5a was partitioned and one side was directly opened and the other was opened to the atmosphere by the opening 29 through the bottom of the hot air generating box 11.

Again, the branch communication port 22 of the return hot air is provided with a dumper 31 which is linked to the operation mechanism 30 operated by the temperature detector built in the blowout duct 2d or the lower blowout duct 4, The amount of return of hot air and the amount of outside air at the outside air inlet 25 are adjusted to obtain low-temperature hot air at a suitable temperature for secondary processing, and the air is blown to blowout ducts 2d and 4 of the secondary processing unit.

In the figure (32) is installed facing the traveling path of the conveyor (6) at a position where it is difficult to suck the blow-out hot air from the blowout duct (2a), in the upper front position of the horizontal half-shaped blowout duct (4) One suction duct was displayed, and one end thereof was communicated with the air passage 13b by the air vent 33. Reference numeral 34 denotes an air volume adjusting damper installed in an air vent or aeration passage, 35 a burner of a heating furnace, and 36 a kite. In this apparatus, relatively high temperature hot air from the hot air generation 11 is sent to the blowout ducts 2a and 2c in the processing chamber 1 through the vents 18 and 19, and is blown out. Drying treatment is performed for the degenerated feces of the traveling conveyor 6, and the processing hot air is sucked into the suction ducts 3a and 3b and the auxiliary suction duct 32. As shown in FIG. Therefore, in the A-B section in the processing chamber 1 shown in FIG. 2, the primary treatment by the dryness of the coefficient to high temperature hot air is performed. The hot air sucked from the suction ducts 3a and 32 is refluxed into the blower chamber 9a of the hot air generating 11 from the vents 20 and 33 via the air passage 13b. Recirculated by 10) and circulated. In addition, the hot air sucked into the suction duct 3b is returned to the blower chamber through the air passage 21 through the air passage 13c, but a part of the air flows from the outside air inlet 25 after passing through the communication port 22. In the BC section in FIG. 2 by feeding air into the secondary processing blowout duct 2d and the lower flat blowout duct 4 of the processing chamber 1 by the blower 27 as a low temperature hot air. In the CD section, the secondary treatment by the reduction rate drying is performed by the relatively low temperature hot air, and then, in the CD section, the outside air drawn in from the blower 16 is taken out from the blowout duct 4a and subjected to the return treatment. Although the processing hot air blown out from the () is discharged from the rear suction duct (3c) via the exhaust pipe (15), approximately half the amount of hot air sucked into the suction duct (5) opposed to the flat-shaped blowout duct (4) To the atmosphere at the opening 28 The part returns from the air vent 26 to the air passage 13d, returns to the blower chamber 9a with the reflux heat of the air passage 13c, and uses the remaining heat.

In addition, the return processing air sucked by the suction duct 5a to the outside air blowout duct 4a is discharged to the atmosphere from the openings 29 on both sides.

In this way, the Haitai bal brought into the processing chamber 1 from the inlet 7 is required after the first treatment by the constant drying by high temperature hot air in the first step of the circumference, and then by the second treatment by the low temperature hot air. In some cases, a return treatment is carried out to remove the damage caused by overdrying, and is taken out of the outlet 8 and taken out as a product.

The blowers 9, 16, and 27 may be of any type, such as centrifugal type or axial flow type.

In this way, according to the present invention, the first and second drying treatments and the return treatment may be continuously performed in the treatment chamber 1, and the treatment hot air of the drying conditions suitable for each treatment can be easily obtained. Part of the waste water can be recycled to use the remaining heat, thereby reducing and saving fuel costs, and at the same time increasing the heat efficiency. Also, the hot air treatment chamber 1 and the hot air generator 11 and the hot air exhaust box 12 can be separated from time to time. It is effective in assembling, inspecting, maintaining, cleaning and preserving ventilation, etc., and obtaining an extremely effective drying device as part of Haitai manufacturing automation.
