Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will recognize without departing from the spirit and scope of the present invention.

In one embodiment, referring to fig. 1, a garbage chute exhaust apparatus 100, the garbage chute exhaust apparatus 100 comprises: standpipe 110, storage line 120, on-off valve 140, and exhaust assembly 130. Standpipe 110 includes a first orifice 111 and a second orifice 112 disposed opposite to each other. The first nozzle 111 is disposed near the top of the building 300 opposite the second nozzle 112 and communicates with the atmosphere. One end of the storage tube 120 is communicated with the second nozzle 112, and the other end of the storage tube 120 is adapted to be connected to the delivery tube 200 through the on-off valve 140. The exhaust assembly 130 includes an exhaust pipe 131 and a fan 132 installed in the exhaust pipe 131. One end of the exhaust pipe 131 is connected to the storage pipe 120, and the other end of the exhaust pipe 131 is connected to the delivery pipe 200. The fan 132 is used for driving the airflow to flow through the vertical pipe 110, the exhaust pipe 131 and the delivery pipe 200 in sequence.

In the exhaust device 100 for the vertical garbage chute, in the exhaust process, the on-off valve 140 is closed to block the communication between the storage pipe 120 and the conveying pipe 200, and at this time, the garbage in the vertical pipe 110 can fall into the storage pipe 120 from the second pipe opening 112 for buffering; the fan 132 is started, and the fan 132 drives the airflow to sequentially flow through the vertical pipe 110, the exhaust pipe 131 and the conveying pipe 200, so that the odor in the vertical pipe 110 is pumped into the conveying pipe 200 from top to bottom and is conveyed into the collection station along with the conveying pipe 200 for treatment. Therefore, the garbage vertical groove exhaust device 100 adopts a downward pumping mode, changes the traditional roof exhaust mode, does not need to arrange an activated carbon filter device on the roof, utilizes the filter device in the original collection station, and economically and effectively prevents the peculiar smell from overflowing. Meanwhile, one end of the exhaust pipe 131 is communicated with the storage pipe 120, and the other end of the exhaust pipe 131 is communicated with the conveying pipe 200, so that the fan 132 positioned in the exhaust pipe 131 is far away from the top of the building 300, and thus, the noise of the fan 132 is prevented from being diffused at high altitude, and the hidden trouble that the noise disturbs people is effectively avoided.

In addition, when the amount of the garbage in the storage pipe 120 reaches a preset amount, the on-off valve 140 is opened so that the storage pipe 120 communicates with the transfer pipe 200. The vacuum is now activated to draw waste into the duct 200 under negative pressure (and of course the valve structure above the storage tube 120 is closed accordingly) for concentrated transport to the collection station. Wherein, the end of the delivery pipe 200 far away from the storage pipe 120 is communicated with a vacuum device.

It should be noted that the standpipe 110 is vertically installed in the building 300, and the standpipe 110 should pass through each floor of the building 300, so that the garbage can be thrown into the standpipe 110 by the residents or renters on each floor. The first pipe opening 111 of the standpipe 110 can extend directly through the top of the building 300 (i.e., the roof), and may not extend through the top of the building 300. When the first nozzle 111 does not penetrate the top of the building 300, a ventilation pipe 310 is disposed on the top of the building 300 and is communicated with the first nozzle 111, so that the first nozzle 111 is communicated with the atmosphere. In addition, the second pipe port 112 of the vertical pipe 110 should extend to the bottom of the building 300, and the exhaust assembly 130 and the storage pipe 120 are located below the vertical pipe 110. Such as: the second nozzle 112 extends into the equipment room at the bottom of the building 300, and the exhaust assembly 130 and the storage pipe 120 are located in the equipment room, below the standpipe 110, and so on.

It should be further noted that the fan 132 is disposed in the exhaust pipe 131 and can drive the airflow to flow through the vertical pipe 110, the exhaust pipe 131 and the conveying pipe 200 in sequence, and the implementation manner can be as follows: the air outlet end of the fan 132 is disposed toward the end of the exhaust pipe 131 close to the delivery pipe 200, and the like. Meanwhile, when the exhaust pipe 131 is connected to the storage pipe 120, it can be connected to the end of the storage pipe 120 close to the second nozzle 112 as much as possible, so as to effectively enlarge the effective volume of the storage pipe 120. Of course, in other embodiments, one end of the exhaust pipe 131 may be connected to other parts of the storage pipe 120, even connected to a valve structure on the storage pipe 120, so as to achieve indirect communication with the storage pipe 120, etc. In addition, the other end of the exhaust pipe 131 may be in direct communication with the delivery pipe 200; or indirectly, such as: the exhaust pipe 131 communicates with a part of the on-off valve 140.

Further, referring to fig. 1, the on-off valve 140 includes a housing 141 and a first valve 142. The storage tube 120 is used to connect with the delivery tube 200 through the housing 141. The first valve 142 is disposed in the casing 141 and is used for controlling the connection between the storage tube 120 and the delivery tube 200. In this way, the first valve 142 effectively controls the connection and disconnection between the storage pipe 120 and the delivery pipe 200, so that the garbage can be stably buffered and emptied.

Further, the exhaust pipe 131 is connected to the case 141. The exhaust pipe 131 is used to maintain a communication state with the delivery pipe 200 through the housing 141. Therefore, the exhaust pipe 131 is indirectly communicated with the delivery pipe 200, that is, in the exhaust process, the airflow is sucked into the vertical pipe 110 from the first nozzle 111 under the action of the fan 132; then flows into the exhaust pipe 131 from the second pipe opening 112 through the vertical pipe 110; finally, the exhaust gas flows from the exhaust pipe 131 into the casing 141 and the delivery pipe 200 in this order, thereby achieving stable exhaust. Among them, it should be understood that the exhaust pipe 131 is in communication with the delivery pipe 200 through the casing 141: the first valve 142 in the housing 141 does not affect the communication state between the exhaust pipe 131 and the delivery pipe 200, but only the connection and disconnection between the storage pipe 120 and the delivery pipe 200.

In one embodiment, referring to FIG. 1, the housing 141 has a first chamber 1411, a second chamber 1412, and a port 1413 between the first chamber 1411 and the second chamber 1412. The first valve 142 can be opened to cover the valve port 1413. The first sub-chamber 1411 is in communication with the storage tube 120, and the second sub-chamber 1412 is in communication with the exhaust tube 131 and the delivery tube 200, respectively. In this embodiment, the inside of the casing 141 is divided into two chambers, and the opening degree of the valve port 1413 is controlled by the first valve 142, so as to connect or disconnect the storage tube 120 and the delivery tube 200. Meanwhile, the exhaust pipe 131 and the delivery pipe 200 are both communicated with the second chamber 1412, so that the exhaust pipe 131 and the delivery pipe 200 are always kept in a communicated state through the second chamber 1412, and the peculiar smell in the vertical pipe 110 is stably discharged into the delivery pipe 200 under the action of the fan 132.

It should be noted that the opening and closing manner of the first valve 142 at the valve port 1413 may be a rotation manner or a translation manner. Meanwhile, the action of the first valve 142 may be automatically controlled, such as: the first valve 142 is connected to an output shaft of an air cylinder, a hydraulic cylinder, an electric cylinder, or the like.

In one embodiment, referring to fig. 1, the exhaust assembly 130 further includes a first control valve 133. The first control valve 133 is installed on the exhaust pipe 131 and used for controlling the on/off of the air flow in the exhaust pipe 131, that is, when the first control valve 133 is closed, the air flow in the exhaust pipe 131 is blocked, so as to block the communication between the exhaust pipe 131 and the delivery pipe 200. This closes the first control valve 133 when the waste is emptied, to effectively prevent the reverse flow of the air flow in the conveying pipe 200.

The first control valve 133 may be configured in various ways as long as the flow of the air in the exhaust pipe 131 can be turned on and off.

Specifically, referring to fig. 2, the first control valve 133 includes a driver 1331 and a plugging member 1332, the plugging member 1332 is rotatably installed in the exhaust pipe 131, and the driver 1331 is drivingly connected to the plugging member 1332. At this time, when the closing member 1332 is rotated, the inside of the exhaust pipe 131 can be closed or opened to block or block the flow of the air current in the exhaust pipe 131. The size of the blocking piece 1332 should be consistent with the inner size of the exhaust pipe 131, for example: the exhaust pipe 131 is circular, and the outer contour of the sealing piece 1332 is also circular. Meanwhile, the driver 1331 may be an air cylinder, a hydraulic cylinder, an electric cylinder, or the like.

In one embodiment, referring to FIG. 2, the exhaust assembly 130 further includes a filter element 134. The filter 134 is disposed in the exhaust pipe 131. So, filter the air current that flows into in the blast pipe 131 through filtering piece 134, filter the solid particle who carries, avoid taking place long-pending material in the blast pipe 131 and easily leading to the jam, realize the primary filter effect.

In the present embodiment, referring to fig. 1 and fig. 2, the filter 134 is located between the first control valve 133 and the storage tube 120. During emptying of the waste, the on-off valve 140 is opened and the first control valve 133 is closed. At this time, the garbage in the storage pipe 120 is sucked into the transport pipe 200 by the negative pressure in the transport pipe 200. Because the first control valve 133 is in the closed state, the airflow between the first control valve 133 and the filter element 134 is subjected to the negative pressure in the storage tube 120, and impacts the filter element 134, so as to blow back the filter element 134. Thus, the cleaning effect of the filter member 134 is facilitated.

Of course, in order to enhance the cleaning effect of the filter members 134, a cleaning valve (not shown) may be provided on the exhaust pipe 131 between the first control valve 133 and the filter members 134. When first control valve 133 was closed, the clearance valve was the open mode for exhaust pipe 131 between first control valve 133 and the filter piece 134 communicates with the external world, thereby makes the external gas pass through clearance valve blowback filter piece 134, and then further improves the clearance effect of filter piece 134.

It should be noted that the cleaning valve may be, but not limited to, a butterfly valve, a ball valve, a proportional valve, etc. In this regard, the present embodiment is not particularly limited, and it is sufficient that when the purge valve is opened, the outside air can enter the exhaust pipe 131 between the first control valve 133 and the filter member 134 through the purge valve.

In another embodiment, the first control valve 133 is a three-way valve (not shown). A first end of the three-way valve is communicated with a portion of the exhaust pipe 131 close to the storage pipe 120, a second end of the three-way valve is communicated with a portion of the exhaust pipe 131 close to the delivery pipe 200, a third end of the three-way valve is used for communicating with the atmosphere, and the three-way valve is used for controlling the first end to be alternatively switched to be communicated with the second end and the third end. Therefore, in the exhaust process, the first end is selectively communicated with the second end, so that the storage pipe 120, the exhaust pipe 131 and the conveying pipe 200 are communicated with each other, and the peculiar smell in the garbage sequentially flows through the storage pipe 120, the exhaust pipe 131 and the conveying pipe 200 and is exhausted. When the filter element 134 is to be cleaned, the first end is selectively connected to the third end, so that the portion of the exhaust pipe 131 between the first control valve 133 and the filter element 134 is connected to the atmosphere. At this time, the gas in the atmosphere is sucked into the exhaust pipe 131 from the third end under the negative pressure in the delivery pipe 200, and flows back to the storage pipe 120 along the exhaust pipe 131, and blows the solid particles on the filter element 134 down to the storage pipe 120, so as to realize the back-blowing cleaning effect on the filter element 134.

In one embodiment, referring to FIG. 2, the inner diameter S of the exhaust 131 is at least partially defined by the inner diameter S of the exhaust 131 ₁ The size of the air outlet pipe 131 is gradually increased from the end connected to the storage pipe 120, so as to slow down the flow rate of the air flowing from the storage pipe 120 to the air outlet pipe 131 and reduce the impact on the structure (such as the filter 134) in the air outlet pipe 131. Meanwhile, one end of the exhaust pipe 131 is enlarged, so that the inflow air flow tends to be gentle, and the negative pressure effect at one end of the exhaust pipe 131 is reduced, so that the suction amount of solid garbage is reduced.

In one embodiment, referring to FIG. 2, the inner diameter S of the exhaust 131 is at least partially defined by the inner diameter S of the exhaust 131 ₂ Gradually increases from the end of the exhaust pipe 131 near the on-off valve 140 to accelerate the flow from the exhaust pipe 131The flow rate of the air flow flowing into the on-off valve 140 increases the impact on the residual garbage in the on-off valve 140, and avoids the blocking phenomenon caused by the accumulation of the garbage in the on-off valve 140.

In one embodiment, referring to fig. 2, the exhaust pipe 131 includes a first pipe segment 1311, a second pipe segment 1312 and a third pipe segment 1313 which are sequentially connected, and the first pipe segment 1311 is connected to the storage pipe 120. The third pipe segment 1313 communicates with the on-off valve 140 or the delivery pipe 200. The fan 132 is installed in the second pipe section 1312.

On the basis of the present embodiment, referring to fig. 2, the first control valve 133 is disposed on the second pipe segment 1312, and the fan 132 is located at a side of the first control valve 133 facing the first pipe segment 1311.

In one embodiment, referring to fig. 1, the refuse chute exhaust 100 further comprises a second control valve 150. The second nozzle 112 is connected to the reserve tube 120 through a second control valve 150. The second control valve 150 is used to control the connection and disconnection between the second nozzle 112 and the storage tube 120. When the amount of the garbage in the storage pipe 120 reaches a preset amount, the on-off valve 140 is opened, and the second control valve 150 is closed, so that the garbage in the storage pipe 120 is sucked into the conveying pipe 200 under the negative pressure.

It should be noted that the second control valve 150 may have various structures as long as the connection and disconnection between the second nozzle 112 and the storage tube 120 can be realized.

Specifically, referring to fig. 1, the second control valve 150 includes a valve body 151 and a second valve 152, and the second valve 152 is movably installed in the valve body 151. When the closing piece 1332 moves, it can close or open the second nozzle 112, so as to open or close the second nozzle 112 and the storage tube 120.

In addition to the present embodiment, referring to fig. 1, the garbage chute exhaust apparatus 100 further includes a fire-fighting module 160. Fire fighting assembly 160 is used to sense a fire condition within standpipe 110 and to extinguish a fire within standpipe 110. Therefore, when the fire fighting module 160 detects a fire in the vertical pipe 110, the second control valve 150 is closed, and a fire extinguishing operation (such as spraying fire extinguishing foam or spraying operation, etc.) is performed in the vertical pipe 110, so as to achieve an effective fire fighting effect. After fire extinguishing, the second control valve 150 is opened, and the blower 132 is turned on (at this time, the on-off valve 140 remains closed), so that the flue gas in the vertical pipe 110 is discharged from the exhaust pipe 131 in time. So, this rubbish erects groove exhaust apparatus 100 not only has the peculiar smell function of discharging, but also has the fire control function of discharging fume, greatly guarantees user or tenant's personal safety in the building 300.

In addition, when the exhaust pipe 131 is provided with the filter 134, the liquid for fire extinguishing can be filtered to remove the solid remaining in the liquid by the filter 134. And the filtered liquid is directly discharged into the conveying pipe 200 under the action of the fan 132.

In one embodiment, referring to FIG. 1, fire fighting assembly 160 includes a fire hose 161, a hose 164, an inductor 163, and a sprinkler head 162. The sprinkler head 162 is connected to the fire hose 161 through a connection pipe 164. The fire hose 161 is used for containing a disinfectant or a disinfectant. The sprayer 162 is mounted on the vertical pipe 110 and is used for spraying liquid into the vertical pipe 110. Sensor 163 and sprinkler head 162 are both adapted to be electrically connected to a controller, and sensor 163 is adapted to sense a fire condition within standpipe 110. When the sensor 163 senses a fire in the vertical pipe 110, the trigger controller controls the spray head 162 to operate to spray in the vertical pipe 110. In addition, when the fire box 161 contains disinfectant, the spray nozzle 162 can be used for regularly spraying and disinfecting the vertical pipe 110.

Alternatively, the controller may be a single-chip microcomputer, an editable logic controller, or the like. Meanwhile, the sensor 163 may be a smoke sensor or a temperature sensor, etc.

Of course, in addition to this embodiment, a spray head 162 may be added to the storage pipe 120 (e.g., the end of the storage pipe 120 near the standpipe 110, etc.). The spray head 162 communicates with a fire box 161. Thus, when the second control valve 150 is closed, the spray nozzle 162 can spray and extinguish fire in the storage pipe 120, and the fire-fighting performance of the garbage chute exhaust device 100 is further improved.

In one embodiment, referring to fig. 1, the refuse chute exhaust 100 further comprises a throwing structure 170.
