Description

Technical Field

[0001] This utility model belongs to the field of waste collection technology, specifically relating to an outdoor negative pressure waste collection station with shredding function. Background Technology

[0002] Negative pressure waste collection stations are advanced waste management facilities that utilize negative pressure technology to automatically collect waste through an underground pipeline system. After residents deposit their waste into the hoppers, the system activates periodically, using vacuum suction to transport the waste to a central collection station for compression and processing. This technology effectively reduces waste exposure and odor spread, lowers the risk of secondary pollution, and improves environmental sanitation. Simultaneously, the stations eliminate the need for frequent transport by traditional garbage trucks, reducing traffic congestion and carbon emissions, making them suitable for high-density urban areas. Negative pressure waste collection stations not only improve waste management efficiency but also promote intelligent urban management, serving as crucial infrastructure for achieving green environmental protection and sustainable development.

[0003] Currently, negative pressure garbage collection stations on the market have some defects. Existing garbage collection stations do not have garbage shredding functions, and garbage blockage often occurs. This utility model optimizes the structural design, reduces the volume of garbage, and greatly reduces the occurrence of blockage. Utility Model Content

[0028] Example

[0029] like Figures 1-2 As shown, this embodiment provides an outdoor negative pressure waste collection station with shredding function, including an equipment installation chamber 1, which is embedded below the ground, with its upper surface flush with the ground. A dispensing mechanism 2 is located on the outside of the equipment installation chamber 1, extending through the upper surface into the chamber. A shredding mechanism 3 is connected to the lower end of the dispensing mechanism 2, and a waste conveying pipe 4 is connected below the shredding mechanism 3. An air inlet valve 5 is located at the inlet end of the waste conveying pipe 4, and its outlet end passes through the side wall of the equipment installation chamber 1 and connects to an outer transport pipe. A discharge valve 6 is also provided between the waste conveying pipe 4 and the shredding mechanism 3, and a height sensor 7 is provided between the discharge valve 6 and the shredding mechanism 3. The shredding mechanism 3, waste conveying pipe 4, air inlet valve 5, discharge valve 6, and height sensor 7 are all located within the equipment installation chamber 1.

[0030] The feeding mechanism 2 and the shredding mechanism 3, as well as the shredding mechanism 3 and the discharge valve 6, are connected by pipes. The discharge valve 6 and the waste conveying pipe 4 are connected by a T-joint.

[0031] It also includes a vacuum power system. When the vacuum power system is running, a negative pressure is formed inside the pipe, creating a pressure difference between the inside and outside of the pipe. Air is drawn into the pipe, and at the same time, the waste is also carried into the pipe by the air for crushing. The vacuum power system is existing technology and will not be described in detail here. Please refer to existing technology.

[0032] This utility model adopts fully automated control, including a controller, an intake valve 5, an exhaust valve 6, and a height sensor 7 electrically connected to the controller.

[0033] In practical application, citizens deposit garbage through the disposal mechanism 2. The garbage is first crushed by the shredding mechanism 3 to reduce its volume and prevent blockage during subsequent transportation. The crushed garbage is temporarily stored in the pipe between the discharge valve 6 and the shredding mechanism 3. When the garbage height reaches the system set value, the height sensor 7 is triggered. The height sensor 7 sends a signal to the controller to open the discharge valve 6, and the stored garbage is discharged into the garbage conveying pipe 4, which is then transported to the collection station for processing through an external conveying pipe. At the same time as the discharge valve 6 opens, the air inlet valve 5 also opens. After the operation is completed, the air inlet valve 5 and the discharge valve 6 automatically close.

[0034] In one embodiment, the equipment installation chamber 1 has an entrance that is large enough to allow an adult to pass through.

[0035] Specifically, the entrance is surrounded by a protrusion 8 with an opening at the top. The opening is large enough for an adult to pass through and has a door. A ventilation device is provided around the protrusion 8.

[0036] The ventilation device is a louver 9.

[0037] The entrance allows maintenance personnel to easily access the equipment installation room 1 for repairs, and the ventilation system ensures air circulation within the equipment installation room 1.

[0038] To facilitate the work of maintenance personnel, a ladder 10 is provided on the inner wall of the equipment installation chamber 1, and the ladder 10 is located below the entrance; when in use, maintenance personnel open the door on the boss 8, enter from the entrance, and climb down to the bottom of the equipment installation chamber 1 via the ladder 10.

[0039] In one embodiment, the shredding mechanism 3 includes a housing 31. A motor 32 is disposed on the outer side of the housing 31. A gear 33 is connected to the output shaft of the motor 32. The gear 33 meshes with a gear 34. The gear 34 is synchronously connected to a gear 36 via a transmission shaft 35. The gear 36 meshes with a gear 37. The gear 37 is synchronously connected to a transmission shaft 38. The transmission shafts 35 and 38 are both located inside the housing 31. Blade rollers 39 and 310 are respectively connected to the transmission shafts 35 and 38, and the blade rollers 39 and 310 are cross-corresponding to each other. The gears 33, 34, 36, and 37 are all located outside the housing 31.

[0040] In practical applications, the motor 32 is started, and the rotation of the motor 32 drives the first gear 33 to rotate. The rotation of the first gear 33 drives the second gear 34 to rotate. The rotation of the second gear 34 drives the first transmission shaft 35 to rotate. The rotation of the first transmission shaft 35 drives the third gear 36 to rotate. The rotation of the third gear 36 drives the fourth gear 37 to rotate. The rotation of the fourth gear 37 drives the second transmission shaft 38 to rotate. The rotation of the first transmission shaft 35 and the second transmission shaft 38 respectively drives the first blade roller 39 and the second blade roller 310 to rotate in opposite directions, thus crushing and breaking up the waste.

[0041] To facilitate the maintenance of the waste conveying pipeline 4, an inspection port 11 is provided on the waste conveying pipeline 4 near the outlet end. Specifically, the inspection port 11 is an opening on the waste conveying pipeline 4.

[0042] In one embodiment, a support 12 is provided on the inner side of the bottom of the equipment installation chamber 1, and the waste conveying pipe 4 is supported on the support 12.

[0043] In one embodiment, the discharge valve 6 is positioned close to the waste conveying pipe 4, and the height sensor 7 is positioned close to the bottom of the shredding mechanism 3. The placement of the discharge valve 6 close to the waste conveying pipe 4 and the height sensor 7 close to the bottom of the shredding mechanism 3 maximizes the pipe distance between the discharge valve 6 and the height sensor 7, allowing for the storage of more waste and preventing frequent start-ups and shutdowns of the equipment.

[0044] In one embodiment, multiple dispensing mechanisms 2 are provided, each dispensing mechanism 2 being connected to a shredding mechanism 3, a waste conveying pipe 4, an air inlet valve 5, an exhaust valve 6, and a height sensor 7. With multiple dispensing mechanisms 2, and each dispensing mechanism 2 corresponding to a separate shredding mechanism 3, waste conveying pipe 4, air inlet valve 5, exhaust valve 6, and height sensor 7, the pipes corresponding to each dispensing mechanism 2 operate independently. By setting up multiple dispensing mechanisms 2, waste can be classified, and different types of waste can be shredded and transported separately, facilitating subsequent waste recycling and processing.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
