本考案は、家畜類糞尿等の貯溜槽内における曝
気・消泡装置に関するものである。[Detailed Description of the Invention] The present invention relates to an aeration/defoaming device in a storage tank for livestock manure, etc.
家畜類の糞尿をそのまま肥料として圃場散布す

われている。 When livestock manure is directly used as fertilizer to be applied to fields, not only does it have a bad odor, but the Escherichia coli and parasite eggs contained in the manure are also spread, which poses an extremely hygienic problem. For this purpose, livestock excreta is aerated and agitated in a storage tank and stored for a certain period of time.During that time, the temperature rise in the tank kills Escherichia coli and parasite eggs, and it is applied as a hygienic, high-quality fertilizer that eliminates bad odors. things are being done.

焼損を来たす結果となる。 However, when forced aeration of livestock excreta in a storage tank occurs, the generation of air bubbles is significant, and the viscosity of the liquid is also high, making it difficult for air bubbles to disappear, and as shown in Figure 1, air bubbles are generated on the liquid surface. The bubble layer will overflow out of the tank. As a defoaming method, there is a technical idea of rotating a foam face with a motor in the upper part of the storage tank, but the known defoaming device 5' as shown in Fig. 2 eliminates air bubbles and foreign matter. It adheres to the motor frame and causes the motor 7' to lose its cooling function, resulting in burnout of the motor 7' due to long-term operation.

る。 The device of the present invention is equipped with an aeration device that sucks air from the atmosphere through an intake port and discharges it into the storage tank from a discharge port, and an antifoaming device that rotates a foam face with a motor in the upper part of the storage tank. By installing an air cooling outer shell around the outer periphery of the motor frame of the defoaming device, air bubbles and foreign matter are prevented from adhering to the motor frame, and the air inlet of the aeration device is connected to the air cooling device. By communicating with the atmosphere above the liquid surface through the outer periphery,
The structure is such that outside air passes through the outer shell while the aeration device is running, increasing the cooling effect of the motor.

る。 Referring to FIG. 3, which shows an example of an embodiment of the device of the present invention, 1 is a storage tank in which livestock excrement, etc. is stored, and 2 is an aeration device installed in the storage tank 1, which sucks air from the atmosphere. It has the effect of sucking in through the port 3 and discharging it in the form of bubbles into the storage tank 1 through the discharge port 4. Reference numeral 5 denotes a defoaming device installed in the upper part of the storage tank 1, and is configured in a sealed manner by surrounding the outer periphery of a frame of a motor 7 that rotates a foam face 6 with an air cooling outer body 8. Reference numeral 9 denotes an air intake conduit for communicating the air intake port 3 of the aeration device 2 to the atmosphere above the liquid level, and its inlet portion 9a into the tank is guided down from a part of the wall of the air cooling outer shell 8 to conduct the intake air. It is opened into the port 3, and the outlet portion 9b outside the tank is led out from a part of the wall of the air cooling outer shell 8 above the liquid level and opened into the atmosphere.

フレームに直接附着することを防止し得る。 The tank liquid sucked in through the liquid suction port 10 as the aeration device 2 is driven is discharged from the discharge port 4 and stored in the storage tank 1.
However, in response to this suction and exhaustion, atmospheric air sucked through the intake port 3 is injected into the storage tank 1 from the discharge port 4 in the form of bubbles. The bubble layer generated on the liquid surface by continuing to drive the aeration device 2 is defoamed by the drive of the defoaming device 5. The air above the liquid level sucked in from the outside-tank outlet portion 9b circulates inside the air-cooling outer shell 8, absorbs the heat of the motor 7, and reaches the inside-tank introduction portion 9a, where it acts as a heat dissipator. Therefore, the motor 7 is cooled and the temperature of the liquid in the tank is increased. In the treatment of livestock manure, a high liquid temperature is effective in speeding up the treatment, so the heat dissipation effect within the storage tank 1 results in accelerating the treatment of manure. Furthermore, the air cooling outer shell 8 that is provided around the outer periphery of the frame of the motor 7 can prevent air bubbles and foreign matter from directly adhering to the motor frame.

尿処理の効果を高め得るという利点がある。 As mentioned above, according to the device of the present invention, the defoaming device 5
By attaching the air-cooling outer shell 8 to the motor frame, air bubbles and foreign matter are not attached to the motor frame, and the cooling effect of the motor 7 is enhanced by the outside air circulating inside the air-cooling outer shell 8. Therefore, there is no risk of burnout of the motor 7 even if the defoaming device 5 is operated continuously for a long time. Further, there is an advantage that the absorbed motor heat can be converted into an effect of increasing the temperature of the liquid in the tank, thereby increasing the effectiveness of excrement treatment.
