ShinMaywa Vacuum Type Refuse Collecting and Transporting System "TECHNOCUUM"

(OUTLINE)

This highly advanced system uses a vacuum type underground pipe network to load household refuse from underground refuse storage tanks by way of a loading station into a dedicated refuse collecting vehicle, called refuse collector.

(FEATURES)

 1. Improved working condition Since the collecting work is carried out free
    from direct contact with the refuse that threatens contagions, ensuring a 
    better working condition.

2. Reduced collecting costs A vacuum refuse collector operated by a single person automatically collects the refuse by way of an loading station thus minimizing the collecting costs.

3. Satisfactory customer service Residents are allowed to put refuse into disposal chutes or posts at any time. It is not necessary to keep a refuse container or to remember the date of disposal of household refuse anymore.

4. Good urban landscapes Refuse-free streets provide a sanitary and good looking landscape and foul odors emitted from the rotting refuse in the past are entirely eliminated.

5. Low maintenance costs Simple design and components employed remarkably reduces maintenance costs.

6. Adaptability This system is flexibly adaptable for use at a single building as well as at huge apartment complexes and extensible depending on the needs and budgets.

"TECHNOCUUM" Refuse Collecting and Transporting System
Refuse is disposed of via an indoor disposal chute provided on each floor of a building or outdoor disposal posts in front of the building and then temporarily stored in underground storage tanks. The stored refuse is loaded, by utilizing vacuum suction force, into a refuse collecting vehicle through an underground pipe network and a loading station.

(OPERATION PROCESS)

a) Household refuse is directly disposed of either by putting it in an indoor refuse 
   disposal chute or outdoor refuse disposal post.

b) All refuse that have been disposed of via disposal chutes and posts are temporarily stored in storage tanks.

c) To load the refuse from a storage tank into the refuse collector, a suction hose is to be connected to the loading station which is provided at a proper location and intervals so as to fully cover all storage tanks belonging to the system.

d) IN or OUT gate of the storage tank opens or closes as a control signal is so sent from the refuse collector.

e) To suck refuse from the selected storage tank, a negative pressure of approximately minus 3,500 mmAq is to be applied from the collector so that an air intake valve of the tank is open and refuse in the tank is swirled away into the collector.

f) When the refuse contained in one of the tanks has been fully evacuated, the OUT gate of the tank is to be closed to proceed to the next tank to repeat the same procedure.

g) The refuse collection from each of the tanks belonging to a loading station is automatically controlled by the refuse collector connected to the station. In this event, electrical power supply from the building side is not required.

h) After completing all of the refuse collecting works, the suction hose is to be disconnected from the station and the refuse collector is ready for onward transportation.
