The present invention relates to an upper burst prevention structure of the sediment feeder using air pressure, and in particular, a large amount of sediment (almost sand) lifted by the sedimentation lifter installed in the sedimentation site of the sewage treatment plant is stored in the sedimentation storage box or the sedimentation storage hopper outside the settlement. It relates to an upper burst prevention structure of the needle transport device using the air pressure configured to prevent the upper portion of the needle transport device using the air pressure to be transported to the burst by the impingement of the needle.

It is well known that in modern industrial societies, the population continues to grow and the sewage of sewage continues to increase.

The raw sewage is treated in a sewage treatment plant, the sedimentation lifting device for removing the sedimentation of sand and the like introduced into the sewage sediment in the main facilities of the sewage treatment plant plays an important role as one of the purification means, The sedimentation lifter is to scrape sand and other traces of foreign matter accumulated on the bottom of the settlement, which is a rectangular concrete structure, into a bucket and discharge it to the outside of the settlement.

In general, the method of transferring the sedimentation from the sedimentation basin installed in the sewage treatment plant underground to the sedimentation storage box or the sedimentation hopper on the ground is a bucket type salvage lifter and scrapes the sedimentation from the settlement. When put into the flight conveyor, the flight conveyor drops the sand back to the bucket of the wire rope-type immersion skip hoist, and the bucket is pulled up using the wire rope above the immersion storage box or immersion storage hopper installed on the ground. It is stored in the inside of the settling storage hopper or the settling storage box.

However, there has been a problem in that pollution of the surrounding environment and sanitary adverse effects due to the generation of odors due to the exposure of the bucket of the acupuncture skip hoist or scattering of the acupuncture were adversely affected.

In order to solve the above problems, the application of the registered patent application No. 20-228972, "Applied to the dewatered contaminant transfer apparatus using the air pressure in which the crushing quantity transfer device is installed," conveys the sediment by using the contaminant transfer apparatus using the air pressure. The method is to install the acupuncture device using the air pressure at the rear end of the flight type flight conveyor of the acupuncture lifted by the acupuncture lifter in the sedimentation basin of the sewage treatment plant between the flight conveyor and the needle feeder and the sealed needle of the needle feeder It is configured to directly inject sedimentation without contamination of surrounding environment such as odor occurrence or scattering of sediment into the inside of the external sedimentation storage box or the sedimentation storage hopper through the pipe.

That is, as shown in Fig. 1, the needle feeder using the pneumatic pressure is provided with a hemispherical valve 13 formed with a sealed holding portion 12 around the lower portion of the hopper 11, An air passage 17 for injecting compressed air in an inward direction of the immersion receiving portion 14 is formed at a predetermined portion of the immersion receiving portion 14 having a shape of the upper and lower straits, and is formed below the immersion receiving portion 14. A venturi portion 15 is formed to narrow the transfer passage, and a tubular transfer passage 16 is configured to be connected to the venturi portion 15 to the outside, and the outer side of the immersion receiving portion 14 is provided. The support part 19 is comprised in the outer side of the reinforcement part 18 comprised in this, and since sintering can be conveyed by the air pressure of the air compressed by the compressor to an external immersion storage box or immersion storage hopper, it is a bad smell. Surrounding environment such as outbreak or scatter of sedimentation It is possible to transport long distances without any pollution to it, and it is possible to install the transfer path freely.

However, in the upper portion of the cylindrical wall, by the air pressure injected through the compressed air passage 17, only the remaining portion except the upper portion of the sediment receiving portion 14 is accumulated, the compressed air passage 17 From the position where the immersion receiving portion 14 is installed, the immersion does not accumulate and the space portion is generated, so that phenomena such as sand continue to collide with the wall surface of the portion where the space portion is formed, thereby causing an impact.

Therefore, the portion of the upper part of the wall of the needle feeder (C) using the air pressure made of metal of a predetermined thickness is ruptured by the collision of the needles, and the needle feeder can no longer be used continuously. There was a problem that must be replaced or repaired.

The present invention was devised to solve the above problems, and the upper part of the wall of the needle piercing device using the air pressure to transfer the sand, such as sand from the needle to the needle tip storage box or the needle storage hopper It is an object of the present invention to provide an upper burst prevention structure of the needle sifting feeder using air pressure, which is configured so as not to be rigid, so as to prevent rupture of the upper portion of the wall of the needle feeder.
