この発明は真空吸収式ごみ空気輸送管の清掃方法に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for cleaning a vacuum absorption type waste air transport pipe.

ている。Recently, central waste processing facilities have been set up in housing complexes, etc., and the waste generated from each sutra copying is thrown into a waste chute installed in each building, and this thrown waste is periodically pumped out from the discharge valve installed at the bottom of the sheet. Waste is discharged into a transport pipe, transported by suction through the air transport pipe by a suction blower, and then centrally processed in a waste disposal device, thereby streamlining waste disposal.

着した異物を清掃除去するため、管内壁に密着する外径
を有する円筒状ビグを用い、これを圧縮空気により圧送
して管内清掃を行なっている。By the way, since dirt may remain inside the transport pipe, it is necessary to clean the inside of the transport pipe. One possible cleaning method in this case would be to move a Vig into the pipe. In pipes that transport oil, gas, etc. under high pressure, in order to clean and remove foreign objects firmly attached to the inner wall of the pipe, a cylindrical VIG with an outer diameter that fits tightly against the inner wall of the pipe is used, and this is pumped with compressed air to clean the inside of the pipe. is being carried out.
しかし、この方法は吸引方式のごみ空気輸送管には適用

負荷がかかったり、ブロアの振動が激しくなったりして
ブロアの故障や破損につながるので従来型のビグは使用
できない。However, this method cannot be applied to vacuum-type waste pneumatic transport pipes. In other words, in the case of the suction method, the transport pipe is -0.5k.
Since it is manufactured for a vacuum pressure of about g/Crn2, it is not built to handle high pressure + f'f, so it is not possible to transfer the VIG with high pressure gas, and it is not possible to transfer it to the waste disposal equipment. When using a suction blower to transfer a vig, if a vig that is in close contact with the inner wall of the pipe is used, the suction blower will be overloaded and the blower will vibrate violently, leading to blower failure or damage. Type vig cannot be used.
そこで、発明者等は真空吸引方式のごみ幇気輸送管で、

じて適当な長さとする必要がある。Therefore, the inventors developed a vacuum suction type waste air transport pipe.
As a result of conducting experiments to find out how the inside of pipes could be cleaned using a VIG with a relatively simple configuration, the following findings were made clear. That is, by making the outer diameter of the VIG 0.95 to 0.6 times the inner diameter of the transport pipe, it is possible to transport the VIG at a speed of 60 to 80 inches of the air flow rate in the pipe without overloading the suction blower. can. Since the purpose is not to remove foreign matter stuck to the inner wall of the pipe, but to clean the dirt remaining inside the pipe, even if a pipe with a smaller diameter than the inner diameter of the transport pipe is used, the pipe will not be able to remove the foreign matter that has adhered to the inner wall of the pipe. ,
It performs vertical and horizontal oscillating and oscillating movements in the direction of the tube axis, making it possible to clean residual debris. Still shaking my head,
In order to prevent the VIG from rotating around an axis perpendicular to the tube and clogging the inside of the tube, its length needs to be appropriate depending on the outer diameter of the VIG.

ある。This invention was made based on the above-mentioned knowledge, and its purpose is to create a waste air transport pipe that can be cleaned inside the transport pipe using an existing suction blower using a simple-configured VIG. It is intended to provide a 1'1 cleaning method.

内を清掃することである。The heavy machinery of the present invention that uses the power cleaning method for waste pneumatic transport pipes has a cross-sectional area of the cylindrical pig that is transported in the vacuum suction type waste pneumatic transport pipe to a thickness that does not overload the suction blower, and transports the above-mentioned pig. This is to clean the inside of the transport pipe by vacuum suctioning the inside of the pipe.

にしても良い。In FIG. 1, reference numeral 2 denotes a cylindrical vig which is sucked and transferred within the waste air transport pipe 1. VIG 2 is preferably a foamable synthetic resin that has a relatively strong bond and is harmless even when burned over time (for example, an ethylene styrene car combination). Due to the drastic drop in price, two parts were added to make it possible to eliminate the need for outer skin reinforcement.
1 ratio is preferably 15 times or less. The outer diameter of the Vig 2 is set to 0.95 to 0.6 times the inner diameter of the pipe in order to maintain the porosity and avoid overloading the absorption blower. For example, the pipe inner diameter D is 390+mn and the outer diameter of the pipe is 350 mm. Furthermore, in order to reduce the gap between the inner surface of the pipe and the pipe, when the outer diameter of the pig is increased to 370 mm, a through hole 3 with an inner diameter of 100 mm is drilled in the center in order to maintain the porosity. In addition, in order to promote Big 2's neck and buttocks shaking movement, Big 2
A cut of 0.1 to 0.2D is formed on the tip esso part 3. In order to prevent the big 2 from rotating around the axis perpendicular to the tube and occluding the inside of the tube when swinging, its length is set to 1.5D or more. Furthermore, as shown in FIG. 2, spiral protrusions 5 or grooves 1 may be formed on the outer periphery of the big 2 to generate a spiral movement.

s, at a flow rate of 60 to 80 inches, without overloading the suction blower, the Big 2 is transferred through the pipe 1 with swinging and oscillating movements, and the debris remaining in the pipe is removed. Cleaned and removed. In addition, Pig 2 has just finished cleaning the inside of the pipe.
4th grader, the above ability 1) Example 3: If you mold ' with a synthetic resin that will not cause any harm even if it burns, like the case, it will be a garbage disposal! 11 equipment for incineration. If you want to collect Dou, use Zyclone etc. for 1 minute! All you have to do is collect i11.
