Description

Technical Field

[0001] The utility model relates to the technical field of garbage recycling, in particular to a pneumatic recycling system for garbage in multi-story buildings. Background Art

[0002] In the past, downstairs garbage was regularly collected by property management staff, which was time-consuming and labor-intensive. Furthermore, when garbage collection wasn't done promptly, large amounts of garbage accumulated in vertical garbage chutes, which not only easily became clogged, requiring subsequent manpower to clear, but also became breeding grounds for pests, bacteria, and viruses, leading to odor and air pollution. Furthermore, if garbage isn't cleaned promptly, vertical garbage chutes can easily become breeding grounds for pests, bacteria, and viruses. Furthermore, if garbage isn't properly managed or residents don't properly dispose of their garbage, it can lead to sanitation issues, impacting the hygiene of the entire residential complex. Furthermore, property management staff often use garbage trucks to assist in garbage collection, which inevitably generates high-decibel noise. Furthermore, garbage chutes are often located in the core areas of multi-story buildings, which inevitably impacts residents' living experience, especially late at night and early in the morning. Therefore, technical personnel are urgently needed to address these issues. Utility Model Content

[0003] Therefore, in view of the above-mentioned existing problems and defects, the designers of the present invention collected relevant information, conducted multiple evaluations and considerations, and continued to experiment and modify after many years of R&D experience by technicians engaged in this industry, which ultimately led to the emergence of the pneumatic waste recovery system for multi-story buildings.

[0004] To address the above-mentioned technical problems, the present invention relates to a pneumatic waste recovery system for multi-story buildings. It utilizes airflow energy to collect solid waste deposited at various locations within the multi-story building. Each building unit in the multi-story building is equipped with a vertical shaft-type waste delivery channel. Along the height of the vertical shaft-type waste delivery channel, a linear array of indoor waste delivery openings is arranged for receiving solid waste deposited by residents on different floors. At least one outdoor waste delivery location is located on the periphery of the multi-story building for receiving solid waste deposited by passersby. The pneumatic waste recovery system for multi-story buildings includes a waste collection box, a negative pressure generating unit, and a waste collection pipeline. Along its length, the waste collection pipeline is equipped with both an outdoor waste receiving port compatible with the outdoor waste delivery location and an indoor waste receiving port compatible with the vertical shaft-type waste delivery channel. The waste collection box is connected to the waste collection pipeline and, supplemented by the negative pressure generating unit, allows solid waste collected through the indoor waste delivery openings and / or the outdoor waste delivery location to be collected in the waste collection box under the continuous action of negative pressure.

[0005] As a further improvement of the technical solution disclosed in the present utility model, the pneumatic garbage recovery system for multi-story buildings also includes a garbage temporary storage pipeline, a garbage temporary storage device, and a garbage guide pipeline.

The feed port of the garbage temporary storage pipeline is connected to the vertical shaft type garbage delivery channel. The discharge port of the garbage guide pipeline is connected to the garbage recovery pipeline. The garbage temporary storage device remains in a normally closed state. As time goes on, the amount of garbage temporarily stored in the garbage temporary storage pipeline increases day by day, and the garbage temporary storage device is switched to an open state, so that the temporarily stored garbage can enter the garbage recovery pipeline through the garbage guide pipeline.

[0006] As a further improvement of the technical solution disclosed in the present invention, the garbage temporary storage device includes a shell, a swing mechanism, a flat-opening material retaining unit and a power unit.

The flat-opening material retaining unit is used to realize / remove the isolation of the garbage flow path, and it uses the shell as the assembly basis. The swing mechanism is matched with the flat-opening material retaining unit, and it is assembled in the cavity of the shell. The power unit is used to drive the swing mechanism, and it uses the outer wall of the shell as the assembly basis. The swing mechanism swings due to the rotational torque from the power unit, and the opening and closing degree of the flat-opening material retaining unit is changed.

[0007] As a further improvement of the technical solution disclosed in the present invention, the casement baffle unit includes a casement baffle plate and a hinge. The casement baffle plate is assembled in a rotationally articulated manner with the shell by means of at least two hinges. The rocking mechanism includes a rocking arm, a rotating shaft, and a roller assembly. The rotating shaft passes through the shell and serves as a mounting and fixing base for the rocking arm. The roller assembly is detachably fixed to the free end of the rocking arm. The roller assembly includes a mounting frame and a roller that contacts the bottom wall of the casement baffle plate. The rotating shaft performs circumferential rotational motion due to the action of the rotational torque, and the rocking arm performs a swinging motion. The opening and closing degree of the casement baffle plate changes due to the pushing force from the roller. At the same time, the roller continuously performs circumferential rotational motion due to the rolling friction force from the bottom wall of the casement baffle plate.

[0008] As a further improvement to the technical solution disclosed in the present invention, the power unit includes a load-bearing suspension frame, a first cylinder, and an L-shaped torque transmission member. The load-bearing suspension frame is used to support the first cylinder and is removably fixed to the top wall of the housing. One end of the L-shaped torque transmission member is hingedly connected to the piston rod of the first cylinder, and the other end is fitted onto the rotating shaft. During the extension and retraction movement of the piston rod of the first cylinder, the L-shaped torque transmission member performs a yaw motion due to the drag force, while the rotating shaft simultaneously performs a circumferential rotational motion due to the transmitted rotational torque.

[0009] As a further improvement to the technical solution disclosed in this utility model, the pneumatic waste recovery system for multi-story buildings also includes a pneumatic slide valve. This pneumatic slide valve is used to block the flow of solid waste within the temporary waste storage pipeline and prevent odor from the stored solid waste from spreading toward the indoor waste delivery port. It is compatible with the temporary waste storage pipeline.

[0010] As a further improvement of the technical solution disclosed in the present invention, the negative pressure generating unit includes a negative pressure blower and an air pipeline.

The anemometer is matched with the gas pipeline to measure the flow rate of the negative pressure gas in the gas pipeline. The opening adjustment valve is installed on the gas pipeline. The frequency converter is matched with the self-powered motor of the negative pressure fan. The valve controller is matched with the opening adjustment valve. The transmitter is used to convert the physical quantity of the flow rate measured by the anemometer into an electrical signal. Under the intervention of the frequency converter, the operating power of the self-powered motor of the negative pressure fan can be adaptively adjusted. At the same time, under the intervention of the valve controller, the opening and closing degree of the opening adjustment valve can be adaptively adjusted.

[0012] As a further improvement of the technical solution disclosed in the present invention, the negative pressure generating unit further includes a dust removal and deodorization device. The dust removal and deodorization device is matched with the negative pressure fan and is connected to the air outlet end of the negative pressure fan.

[0013] As a further improvement to the technical solution disclosed in this utility model, the pneumatic waste recovery system for multi-story buildings also includes an unpowered roof fan. The unpowered roof fan is used to support the vertical shaft-type waste delivery channel, allowing for free ventilation between the vertical shaft-type waste delivery channel and the external environment.

[0014] In practical applications, the pneumatic waste recovery system for multi-story buildings disclosed in this utility model can achieve at least the following beneficial technical effects, specifically:

[0015] 1) Abandoning the traditional mode in which the property staff is responsible for cleaning up the garbage downstairs, in the present invention, the negative pressure generating unit and the garbage recovery pipeline work together, and the negative pressure effect can be used to automatically gather the solid garbage piled at the bottom of the vertical garbage delivery channel into the garbage collection box. In this way, on the one hand, by utilizing the energy of the airflow, the solid garbage delivered from different points moves along the direction of the airflow in the garbage recovery pipeline, which has the advantages of large garbage transportation volume, long transportation distance, and fast transportation speed; on the other hand, the garbage in the vertical garbage delivery channel can be cleaned up in time, which can effectively avoid the blockage of the vertical garbage delivery channel and the breeding of mosquitoes and bacteria; on the other hand, a one-time investment and long-term benefits can greatly reduce the human and material costs required by the property company in garbage collection and transportation;

[0016] 2) After the solid waste is collected in the waste collection box, the negative pressure generating unit can continue to move for a period of time. With the help of high-speed wind, the waste collection pipeline and the inner wall of the shaft-type waste delivery channel can be quickly and efficiently cleaned by side blowing. This not only helps to completely remove the solid waste, but also prevents the accumulation of thick dirt or sticky or wet solid waste on the inner wall of the waste collection pipeline and the shaft-type waste delivery channel due to long-term use. It paves the way for reducing the total resistance of the pipeline network during the movement of solid waste along the airflow direction.

[0017] 3) It is easy to adjust the location of the garbage collection bins, and only the length of the garbage collection pipe needs to be adjusted. Garbage collection bins are usually located in remote locations in residential areas, which effectively reduces the adverse impact of the noise generated by property staff when loading and transporting garbage on the residents' living experience;

[0018] 4) Outdoor garbage disposal points are also located outside multi-story buildings to facilitate solid waste disposal by passers-by within the community. These indoor garbage disposal points within multi-story buildings and the outdoor garbage disposal points outside multi-story buildings work together to form a multi-level, three-dimensional garbage disposal point system within the residential area.

DETAILED DESCRIPTION

[0027] In the 1970s and 1980s, a large number of multi-story residential buildings in my country were equipped with vertical shaft-type garbage disposal channels. Along the height of these shafts, a linear array of indoor garbage disposal outlets were arranged to receive solid waste from residents on different floors. Residents did not need to go downstairs; they simply threw their garbage into their own channels, and the garbage would slide down the channels to the lower floor. To accommodate passersby within the residential area, multiple outdoor garbage disposal points were also arranged within the residential areas to receive solid waste from passers-by. These indoor garbage disposal outlets located within multi-story buildings and the outdoor garbage disposal points located outside of them worked together to form a multi-layered, three-dimensional garbage disposal point system within the residential area.

[0028] In order to address various problems existing in the existing garbage collection process (described in detail in the background technology), the utility model discloses a pneumatic garbage recovery system for multi-story buildings, which uses the energy of air flow to collect solid garbage dropped from different points of the multi-story building.

[0029] The following is a further detailed description of the present invention in conjunction with specific embodiments. Figure 1 The schematic diagram of the first embodiment of the pneumatic waste recovery system for multi-story buildings disclosed in this utility model is shown. The system primarily comprises a waste collection box 1, a negative pressure generating unit 2, and a waste retrieval pipeline 3. Along its length, the waste retrieval pipeline 3 is provided with both an outdoor waste receiving port 31 compatible with the outdoor waste placement location and an indoor waste receiving port 32 compatible with the vertical shaft waste placement channel. The waste collection box 1 is connected to the waste retrieval pipeline 3 and, with the assistance of the negative pressure generating unit 2, solid waste collected via the indoor waste placement port and / or the outdoor waste placement location is continuously collected into the waste collection box 1 under the effect of negative pressure.

[0030] In practical applications, the pneumatic waste recovery system for multi-story buildings disclosed in the present utility model has achieved at least the following beneficial technical effects, specifically:

[0031] 1) In the present invention, the negative pressure generating unit 2 and the garbage recovery pipeline 3 work together, and the negative pressure effect can be used to automatically gather the solid garbage piled at the bottom of the vertical garbage delivery channel into the garbage collection box 1. This abandons the traditional operating mode in which the solid garbage that falls along the vertical garbage delivery channel and accumulates downstairs is cleaned up by the property staff. In this way, on the one hand, by utilizing the energy of the airflow, the solid garbage delivered from different points moves along the direction of the airflow in the garbage recovery pipeline 3, which has the advantages of large garbage transportation volume, long transportation distance, and fast transportation speed; on the other hand, the garbage in the vertical garbage delivery channel can be cleaned up in time, thereby effectively avoiding the blockage of the vertical garbage delivery channel and the breeding of mosquitoes and bacteria; on the other hand, a one-time investment and long-term benefits can greatly reduce the human and material costs required by the property company in garbage collection and transportation;

[0032] 2) After the solid waste is gathered in the waste collection box 1, the negative pressure generating unit 2 can continue to move for a period of time. With the help of high-speed wind force, the waste recovery pipeline 3 and the inner wall of the shaft-type waste delivery channel can be quickly and efficiently cleaned by side blowing. This not only helps to completely remove the solid waste, but also avoids the accumulation of thick dirt or sticky or wet solid waste on the inner wall of the waste recovery pipeline 3 and the shaft-type waste delivery channel due to long-term use, thereby paving the way for reducing the total resistance of the pipeline network during the movement of solid waste along the airflow direction.

[0033] It should also be noted that the specific location of the garbage collection bin 1 can be easily adjusted by property management personnel by simply adjusting the length of the garbage collection pipe 3. Furthermore, the garbage collection bin 1 is typically located in a remote location within a residential complex, effectively reducing the adverse impact of noise generated by property management personnel during garbage loading and transport on the residents' living experience.

[0034] Depend on Figure 1As can be clearly seen, the negative pressure generating unit 2 is primarily composed of a negative pressure blower 21, an air duct 22, an anemometer 23, a transmitter 24, a frequency converter 25, a valve controller 26, and an opening adjustment valve 27. The negative pressure blower 21 has its own power motor and is connected to the garbage collection bin 1 via the air duct 22. The anemometer 23 is coupled to the air duct 22 to measure the flow rate of the negative pressure gas within the air duct 22. The opening adjustment valve 27 is mounted on the air duct 22. The frequency converter 24 is coupled to the power motor of the negative pressure blower 21. The valve controller 26 is coupled to the opening adjustment valve 27. The transmitter 24 is used to convert the physical quantity of flow velocity measured by the anemometer 23 into an electrical signal, and under the intervention of the frequency converter 25, the operating power of the self-equipped power motor of the negative pressure fan 21 can be adaptively adjusted, or, under the intervention of the valve controller 26, the opening and closing degree of the opening regulating valve 27 can be adaptively adjusted.

[0035] In actual use, a series of pressure sensors are positioned within the waste retrieval pipeline 3, opposite the outdoor waste receiving ports 31 and the indoor waste receiving ports 32. The moment solid waste falls into the waste retrieval pipeline 3 via the vertical waste channel or the outdoor waste placement area, the corresponding pressure sensors sense the real-time pressure change, instantly activating the negative pressure blower 21. The solid waste in the waste retrieval pipeline 3 is then drawn into the waste collection bin 1 under the continuous negative pressure effect. Furthermore, as the solid waste is drawn and collected, the anemometer 23 measures the flow rate of the negative pressure gas within the gas pipeline 22 in real time. When the flow rate exceeds the designed value, it indicates that the amount of solid waste remaining in the waste retrieval pipeline 3 is low or is about to be completely cleared. In this case, the operating power of the negative pressure blower 21's self-powered motor is reduced or even shut down. Simultaneously, under the intervention of the valve controller 26, the opening degree of the opening regulating valve 27 is reduced or even closed. When the flow rate is less than the designed value, it indicates that a large amount of solid waste remains in the waste collection line 3. In this case, the operating power of the self-powered motor of the negative pressure fan 21 is increased until it reaches full power. At the same time, under the intervention of the valve controller 26, the opening degree of the opening regulating valve 27 is increased to increase the amount of waste collected per unit time. When the flow rate is zero or close to zero, it means that the waste collection line 3 is blocked or severely blocked. In this case, the self-powered motor of the negative pressure fan 21 is immediately shut down, and property management personnel need to intervene to clear the waste collection line 3.

[0036] As can be seen from the above description, by optimizing the design of negative pressure generating unit 2, the energy consumption of negative pressure fan 21 can be significantly reduced while ensuring efficient and timely collection of solid waste, thus contributing to the national energy conservation, emission reduction and environmental protection plan. More importantly, this also prevents the occurrence of "burning" or "downtime" caused by prolonged overload operation of negative pressure fan 21 due to blockage of waste collection line 3.

[0037] It is known that the negative pressure fan 21 will inevitably emit a large amount of malodorous gas, harmful gas or dust during actual operation, which will have a negative impact on the surrounding environment. In view of this, as a further optimization of the above technical solution, Figure 1 As shown in , the negative pressure generating unit 2 is also equipped with a dust removal and deodorization device 28. The dust removal and deodorization device 28 is matched with the negative pressure fan 21 and is connected to the air outlet end of the negative pressure fan 21.

[0038] According to the above description, although the negative pressure generating unit 2 has been transformed to be energy-saving by using components such as anemometer 23, transmitter 24, frequency converter 25, valve controller 26 and opening regulating valve 27, the design characteristics of the pneumatic waste recovery system for multi-story buildings determine that whenever solid waste is placed through the outdoor waste placement area or the vertical waste placement channel, the negative pressure fan 21 will be started and will not be used until the waste recovery pipeline 3 is completely collected. This will inevitably lead to high energy consumption of the negative pressure generating unit 2 and extremely high operating costs. In view of this, Figure 2 The schematic diagram of the structure of the second embodiment of the pneumatic garbage recovery system for multi-story buildings disclosed in the present invention shows that the difference compared with the first embodiment is that the pneumatic garbage recovery system for multi-story buildings is additionally provided with a garbage temporary storage pipeline 4, a garbage temporary storage device 5, and a garbage guide pipeline 6. The feed port and the discharge port of the garbage temporary storage device 5 are connected to the garbage temporary storage pipeline 4 and the garbage guide pipeline 6, respectively. The feed port of the garbage temporary storage pipeline 4 is connected to the vertical shaft type garbage delivery channel. The discharge port of the garbage guide pipeline 6 is connected to the garbage recovery pipeline 3. The garbage temporary storage device 5 is kept in a normally closed state. In this case, the negative pressure fan 21 is kept in a stopped state. As time goes on, the amount of garbage stored in the garbage temporary storage pipeline 4 increases day by day, and the garbage temporary storage device 5 is switched to the open state. The temporarily stored garbage can enter the garbage recovery pipeline 3 through the garbage guide pipeline 6. The pressure sensor opposite to it senses the real-time pressure change, and the negative pressure fan 21 is started. The solid garbage in the garbage recovery pipeline 3 can be continuously gathered into the garbage collection box 1 under the action of the negative pressure effect, thereby further reducing the energy consumption of the garbage pneumatic recovery system of multi-story buildings.

[0039] It is known that, according to common sense in design, the garbage temporary storage device 5 can adopt a variety of design structures to achieve the temporary isolation and retention of solid garbage in the garbage temporary storage pipeline 4. A few years ago, a foreign manufacturer developed a garbage temporary storage device 5 for purchase. However, its design structure is complex, the price is extremely high, and the actual application effect cannot meet the expected design requirements. In view of this, the technical staff of our company has newly developed a garbage temporary storage device with a simple design structure, easy to manufacture and implement, and good application effect. Figure 3 、 4 As shown in the figure, the garbage temporary storage device 5 is mainly composed of several parts such as a shell 51, a swing mechanism 52, a flat-opening material blocking unit 53 and a power unit 54. Among them, a garbage feed port adapted to the garbage temporary storage pipeline 4 is provided on the top wall of the shell 51. A garbage discharge port adapted to the garbage guide pipeline 6 is provided on the bottom wall of the shell 51. The flat-opening material blocking unit 53 is used to realize / remove the isolation of the garbage flow path, and it uses the shell 51 as the assembly basis. The swing mechanism 52 is matched with the flat-opening material blocking unit 53, and it is assembled in the cavity of the shell 51. The power unit 54 is used to drive the swing mechanism 52, and it uses the outer wall of the shell 51 as the assembly basis. The swing mechanism 52 swings due to the rotational torque from the power unit 54, and the opening and closing degree of the flat-opening material blocking unit 53 is changed.

[0040] Likewise Figure 3 、 4As shown in FIG, the flat opening material retaining unit 53 includes a flat opening material retaining plate 531 and a hinge 532. The flat opening material retaining plate 531 is assembled in a rotationally articulated manner with the housing 51 by means of two hinges 532. The swing mechanism 52 includes a swing arm 521, a rotating shaft 522, and a roller assembly 523. The rotating shaft 522 passes through the housing 51 and serves as a mounting and fixing base for the swing arm 521. The roller assembly 523 is detachably fixed to the free end of the swing arm 521. The roller assembly 523 includes a mounting frame 5231 and a roller 5232 that contacts the bottom wall of the flat opening material retaining plate 531. The rotating shaft 522 performs circumferential rotational motion due to the action of the rotational torque, and the rocking arm 521 is able to perform a swinging motion. The opening and closing degree of the flat opening material baffle 531 changes due to the pushing force from the roller 5232. At the same time, the roller 5232 continuously performs circumferential rotational motion due to the rolling friction force from the bottom wall of the flat opening material baffle 531. In this way, on the one hand, the flat opening material baffle 531 is in a hinged form to achieve assembly with the shell 51, and it can change the opening and closing degree due to the coordinated pushing force from multiple rollers 5232, thereby ensuring that the flat opening material baffle 531 has good movement accuracy and strong supporting capacity, which is conducive to ensuring that the flat opening material baffle 531 reliably and effectively blocks the lower port of the garbage temporary storage pipeline 4; on the other hand, when the flat opening material baffle 531 is in a closed state, the swing arm 521 is maintained in a 90° upright posture, and the power unit 54 needs to output a very small torque at this time, and it is only necessary to maintain the upright posture of the swing arm 521 unchanged.

[0041] Depend on Figure 3 、 4 As can be clearly seen in the diagram, the power unit 54 primarily consists of a load-bearing suspension frame 541, a first cylinder 542, and an L-shaped torque transmission member 543. The load-bearing suspension frame 541 supports the first cylinder 542 and is removably secured to the top wall of the housing 51. One end of the L-shaped torque transmission member 543 is hingedly connected to the piston rod of the first cylinder 542, while the other end is fitted over the rotating shaft 522. As the piston rod of the first cylinder 542 retracts and retracts, the L-shaped torque transmission member 543 experiences a yaw motion due to the drag force. Simultaneously, the rotating shaft 522 experiences a circumferential rotation due to the torque transmitted. This allows the power unit 54 to stably drive the rotating shaft 522 while maintaining a minimalist design and low implementation costs. Furthermore, the first cylinder 542 can instantly provide a high torque output, making it particularly suitable for applications involving high loads and high torque on the rotating shaft 522.

[0042] Depend on Figure 2It can be clearly seen from the figure that the pneumatic recycling system for multi-story buildings is also equipped with a pneumatic slide valve 7. The pneumatic slide valve 7 is used to cut off the flow path of solid waste in the temporary waste storage pipeline 4 and prevent the odor of the temporary solid waste from spreading toward the indoor waste delivery port. It is equipped with the temporary waste storage pipeline 4. Figure 5 As shown in FIG, the pneumatic slide valve 7 primarily comprises a support bracket 71, a sliding plate 72, a roller guide assembly 73, and a second cylinder 74. The roller guide assembly 73 comprises two rows of Gothic-style circular-arc groove guide rollers detachably secured to the support bracket 71. The second cylinder 74 also utilizes the support bracket 71 as a mounting base. With the synergistic effect of the two rows of Gothic-style circular-arc groove guide rollers, the sliding plate 72 is subjected to push-pull forces to perform directional translational motion, thereby achieving / releasing the blockage of the solid waste flow path in the temporary waste storage pipeline 4.

[0043] Figure 6 A schematic diagram of the structure of the third embodiment of the pneumatic waste recovery system for multi-story buildings disclosed in the present invention is shown. It can be seen that the difference between the third embodiment and the pneumatic waste recovery system for multi-story buildings is that the system is further equipped with an unpowered roof fan 8. An unpowered roof fan 8 is installed at the top of each vertical waste delivery channel. In actual use, the unpowered roof fan 8 utilizes the natural wind speed to drive the fan turbine to rotate, and utilizes the principle of air convection inside and outside the vertical waste delivery channel to accelerate and convert any parallel air flow into vertical air flow from bottom to top, thereby significantly enhancing the ventilation effect between the vertical waste delivery channel and the external environment.

[0044] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
