Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ventilation device for a dam weighter for a high-rise building.

"Prior Art" Conventionally, a dust chute and a dam weighter as described in JP-A-59-149201 have been considered as an example of a waste treatment facility in a high-rise building.

Explaining an example of a waste treatment facility by a dam waiter,
In the hoistway that penetrates each floor of the building (high-rise building) up and down, a garbage cage suspended by the wire of the hoisting device is provided so that it can be raised and lowered, and a garbage entrance is provided on the wall of each floor of the hoistway. Furthermore, a structure is provided in the lower part of the hoistway to provide a waste storage device that temporarily stores the waste in the waste cage.

Then, when throwing in the garbage, call the garbage cage to the floor where the garbage dumper is located, and after the garbage cage arrives, throw the garbage into the garbage cage through the garbage loading port, so that the garbage can be dumped. It is a thing. In addition, the garbage cage moves between floors in response to a call, and when the inside garbage becomes full, it descends the hoistway and discharges the inside garbage to the waste storage device. .

"Problems to be solved by the device" However, in the above-mentioned dam waiter-type waste treatment facility, the air in front of the waste cage is compressed as the waste cage moves up and down, which causes odors in the hoistway. There is a risk that air containing air will leak to the floors, which are living quarters, from the gaps such as the dust entrance, and spread the bad odor.

The present invention has been made in view of the above circumstances, and prevents the malodor from spreading when the dam waiter type waste treatment facility is stopped or operating, and also minimizes the operation of the facility to prevent the malodor from spreading. The purpose is to save energy.

"Means for Solving Problems" The present invention proposes means for solving these problems, and is suspended by a wire of a hoisting device in a hoistway that vertically penetrates each floor of a building. A dust cage is installed in a high-rise building dam weighter that can be raised and lowered, and an upper intake pipe and a lower intake pipe are provided in communication with the upper position and the lower position of the hoistway, and Dam for a high-rise building, which is connected to both intake pipes and has exhaust means for sucking and discharging air in the hoistway and control means for selectively operating the exhaust means in synchronization with the hoisting operation signal of the hoisting device. It is used as a waiter ventilation system.

[Action] When the dam waiter is inactive, a weak air upward flow occurs due to the chimney effect inside the hoistway, and the air is discharged to the outside of the building to spread the foul odor to the living area. I can't.

On the other hand, when the dam waiter is activated, the evacuation operation signal selectively activates the exhaust means, and the intake pipe located in front of the movement of the dust cage sucks air in the hoistway and discharges it outside. . For this reason, as the garbage cage moves up and down, the air in front of the movement is prevented from being compressed and the pressure is prevented from increasing, and the pressure inside the hoistway is kept lower than in the living area. No foul odor spread.

In the hoistway located at the back of the moving direction of the garbage cage, moving the garbage cage creates a decompressed atmosphere and does not adversely affect the living area.When the garbage cage stops, it will return to the initial state. .

[Embodiment] An embodiment of the ventilation device for a dam weighter for a high-rise building according to the present invention will be described below with reference to FIG.

In each drawing, reference numeral 1 is a building (high-rise building), 2 is a hoistway, 3 is a dam weighter, 4 is a hoisting device, 5 is a wire, 6 is a garbage cage, 7 is a ventilation device, 8 is an upper intake pipe,
9 is a lower intake pipe, 10 is an exhaust means, 11 is a control means, 12 is a container for storing dust, 13 is a container entrance / exit, 14 is an opening / closing door (fire door), 15 is a dust input part, 16 is a dust transfer device, 17 is a container reversing device, 18 is a storage and discharge facility, 19 is a garbage truck, and 20 is a conveyor section.

The hoistway 2 has a cross-sectional area of, for example, about 2.5 m ² , and the garbage cage 6 has a size such that it can be freely hoisted at a distance from the inside of the hoistway 2. It is attached to the hoisting device 4 in a suspended state.

Explaining the details of the ventilation device 7, the upper intake pipe 8 and the lower intake pipe 9 are arranged in communication with the upper position and the lower position of the hoistway 2, and the switching valve A A deodorizing device 21 having an activated carbon adsorption function or the like is inserted between the upper intake pipe 8 and the lower intake pipe 9 and the exhaust means 10 with B, C and D interposed.

The exhaust means 10 is provided in a connected state with respect to the upper intake pipe 8 and the lower intake pipe 9, and its intake exhaust amount is larger than the air transfer amount per unit time when the dust cage 6 is moved. It is equipped with, for example, a blower, and a garbage cage 6
Is moving at a speed of 60 m / min and the cross-sectional area of hoistway 2 is 2.5
Taking the case of m ² as an example, a device having an intake / exhaust volume of about 150 m ³ per minute is applied.

The control means 11 raises and lowers the hoisting device 4 on the basis of an instruction to call the dust cage 6, and transmits a signal synchronized with this raising and lowering operation signal to the exhaust means 10 by the signal cable 22 so that the dust cage 6 moves upward. When the waste cage 6 moves to the front, the exhaust means 10 connected to the upper intake pipe 8 at the forward position is operated, and when the waste cage 6 moves downward, the one connected to the lower intake pipe 9. Exhaust means
It is supposed to activate 10. Incidentally, in FIG. 1, the signal cable 22 of the lower exhaust means 10 is not shown.

In the exhaust means 10 shown in the lower part of FIG. 1, in the vicinity of the container reversing device 17 and in the vicinity of the loading conveyor 23 for transferring the waste from the storage and discharge facility 18 to the waste collection vehicle 19, An intake hood 24 connected to the lower intake pipe 9 is provided.

Hereinafter, collection of dust using the dam weighter 3 and ventilation by the ventilation device 8 will be described.

When the dam waiter 3 is in a non-operating state, a weak air upflow due to the chimney effect is generated based on the temperature difference between the inside of the hoistway 2 and the atmosphere, and is appropriately provided above the hoistway 2. Since the air in the hoistway 2 is discharged to the outside of the building 1 via a small ventilation port (not shown), the living environment is maintained without the malodorous spread to the living areas on each floor. .

General waste dumping is done by the waste dumper 15 installed on each floor.
Therefore, regardless of the position of the dam waiter 3, the waste is put in the waste container 12 to carry out the waste.

Then, when the garbage storage container 12 is full, when the garbage cage 6 is called up on a floor requiring garbage collection, the dam waiter 3 is activated, and the garbage cage 6 is moved up and down. The exhaust means 10 is selectively operated in synchronization with the signal. For example, when the dust cage 6 is moved upward, the switching valve D is opened and the exhaust means 10 of the upper ventilation device 7 in FIG. 1 is opened.
Is in an operating state, the air above the inside of the hoistway 2 is sucked by the upper intake pipe 8, and is discharged into the atmosphere in a state where the deodorizing device 21 removes a bad odor.

Therefore, with the upward movement of the garbage cage 6,
Although the internal air of the hoistway 2 located above the garbage cage 6 is compressed, if the condition that the exhaust amount by the ventilation device 7 exceeds the compressed air amount by the garbage cage 6 is satisfied,
The internal pressure of the hoistway 2 is kept lower than that of the living area, and the malodor is not diffused into the living area.

The capacity of the exhaust means 10 of the ventilation device 7 (intake and exhaust volume)
Should be set to be larger than the compressed air amount in consideration of the backflow of air around the dust cage 6 when it moves.

On the other hand, when the garbage cage 6 is moved, the inside of the hoistway 2 located on the back side in the moving direction is in a decompressed atmosphere, but since the air in the living area is taken in from the container entrance 13 etc. When the dust cage 6 is brought into a stopped state without adversely affecting it, the exhaust means 10 is stopped, so that the original state is naturally restored.

Then, when the garbage cage 6 is stopped in a state of being aligned with the container entrance / exit 13 of the calling floor, the opening / closing door 14 is pulled up to open the container entrance / exit 13, and thereafter, by the operation of the garbage transfer device 16, the first As shown by the chain line in the figure, the waste container 12 is stored in the waste cage 6, and the container entrance / exit 13 is opened / closed by a door 14.
Is blocked by.

Next, by operating the dam waiter 3, the dust cage 6 containing the dust container 12 is lowered to the lower part of the hoistway 2. In this case, the exhaust means 10 of the lower ventilation device 7 in FIG. 1 is in the operating state, the switching valve D is in the closed state, and the switching valve A is in the open state,
The air in the lower part of the inside of the hoistway 2 is sucked by the lower intake pipe 9, and is discharged into the atmosphere with the odor removed by the deodorizing device 21.

In the state where the garbage cage 6 is lowered to the lowest position of the hoistway 2, the switching valve A is returned to the closed state, and
The waste container 12 is pulled out onto the conveyor section 20, and only the waste in the waste container 12 is transferred to the storage and discharge facility 18 via the container reversing device 17, and by the transfer of the waste [ Empty container for garbage storage
12 is returned to the waste cage 6 again and is stored therein. In this case, even when the raising / lowering operation of the dust cage 6 is stopped, the switching valve B is opened, and the air in the vicinity of the container reversing device 17 is sucked by the intake hood 24 to diffuse the malodor. Prevention is made.

In addition, a conveyor that is installed from the storage and discharge facility 18 to the garbage truck 19
When the dust is transferred via 23, the switching valve C is opened and the intake hood 24 sucks the air in the vicinity of the transfer position to prevent the malodor from spreading.

Then, the garbage cage 6 accommodating the [empty] garbage container 12 is returned to an arbitrary floor by operating the dam waiter 3. In this case, the garbage cage 6
, The upper ventilator 7 in FIG. 1 is operated in the same manner as described above, and parallel operation with the lower ventilator 7 in FIG. 1 is possible.

When the downward movement of the waste cage 6 and the operation of the container reversing device 17, the storage and discharge facility 18, and the waste collection vehicle 19 overlap, the intake by opening the switching valve A is prioritized. .

On the other hand, when a fire alarm is issued based on the occurrence of a fire, the switching valves A and D are closed and the hoistway 2 is shielded.

[Advantages of Device] As described above, the ventilation device for a dam weighter for a high-rise building according to the present invention has the following excellent effects.

(1) Since the upper intake pipe and the lower intake pipe are connected to the hoistway and the exhaust means is selectively operated in synchronization with the lifting operation of the hoisting device, the generation of compressed air accompanying the vertical movement of the dust cage is suppressed. Then, the odorous air in the hoistway is prevented from diffusing a bad odor due to leaking from the gap such as the dust entrance to each floor which is a living area, and does not disturb the living environment.

(2) Since the raising and lowering of the garbage cage and the operation of the ventilation device are interlocked with each other, it is possible to operate the equipment for preventing the malodorous diffusion for a required time to save energy and prolong the service life.
