Description

Technical Field

[0001] This utility model patent design pertains to the structural design technology of special equipment for vacuum pipeline waste collection systems. Specifically, it relates to the structural design of a waste collection and separation device. Background Technology

[0002] With the continuous improvement of people's living standards, new and higher requirements have been placed on the collection, storage, and transportation of community household waste. In response to this change, vacuum collection technology for waste pipes has begun to be piloted in some developed areas. Currently, the collection of waste, whether in residential areas or public places, relies on garbage trucks to collect it from various collection points. This is time-consuming, labor-intensive, and unsanitary, and can easily cause secondary environmental pollution during operation. Furthermore, it fails to meet the requirements for waste sorting and collection, and the presence of garbage trucks in residential areas adds safety risks. To improve the problems caused by waste collection, pneumatic piped waste collection systems have become the best solution. These systems use high-powered fans connected to pipes to collect waste through negative pressure into the garbage truck's container in the machine room. The entire operation can achieve a fully automated and fully enclosed working mode.

[0003] A pneumatic piped waste collection system requires a waste collection and separation device, which is the core equipment of the vacuum piped waste collection system. The function of the separation device is to draw solid waste through a negative pressure pipe into the separation device, where it settles. Appropriate separation technologies, such as filter screens, are designed to ensure effective separation of different types and sizes of waste. While filter screens can accurately separate particles of different sizes, they are prone to clogging, necessitating a self-cleaning mechanism. This invention's separation device uses a filter screen to achieve waste flow and separation, while also facilitating self-cleaning. It allows waste to fall naturally under gravity, reducing the possibility of accumulation and clogging, thus achieving waste collection and facilitating volume compression and storage.

[0004] This utility model designs the waste collection and separation device in sections. The air outlet and air filter are independently designed in an outwardly protruding structure. The filter structure has an inner arc shape, and its radius of curvature is the same as that of the spiral scraper. When the spiral scraper rotates, the scraper surface runs against the inner arc surface, and the waste stuck to the filter screen is pushed off towards the waste outlet by the spiral scraper, reducing the accumulation of waste at the bottom of the collection box and facilitating the collection of waste from the box. Since the scraper shaft is installed on the frame of the air outlet at the top of the triangular cavity collection box, it is convenient for the production and assembly of the device and for maintenance after long-term operation.

[0005] To achieve the above objectives, this application provides the following technical solution: Utility Model Content

[0006] A pneumatic pipeline waste collection and separation device and structure includes a triangular cavity collection box, a waste inlet, a waste outlet, an air exhaust outlet, and an air filter. The structure also includes a waste container and a waste compression mechanism. The waste inlet and outlet are located on the same side of the triangular cavity collection box. The air exhaust outlet is located above the air filter, away from the waste inlet. The air filter includes a filter screen and a spiral scraper. The waste compression mechanism is located directly below the triangular cavity collection box. The waste container is located below the waste outlet of the triangular cavity collection box, on the side of the compression head of the waste compression mechanism. The separation device includes a scraper driver, a waste compression mechanism driver, and a waste container traction driver. The separation device also includes a detection element.

[0007] The waste inlet pipe is bent inward and downward within the triangular cavity collection box. The outer pipe opening of the waste inlet is designed with a flange. A waste baffle is designed in front of the waste inlet pipe. The waste baffle designed within the triangular cavity collection box is only installed on the pipe directly opposite the waste inlet and does not affect the airflow from the side and bottom.

[0008] The waste outlet is designed at the lowest position of the bottom plate of the triangular cavity collection box. It is the intersection of the waste inlet of the waste container and the compression head and compression chamber. The area of ​​the waste outlet is larger than the horizontal area of ​​the compression chamber, and the waste inlet and waste outlet are not in the same vertical position.

[0009] The air outlet and the filter screen of the air filtration device are independently designed in an outwardly protruding structure. The filter screen is in the shape of an inner arc, and its radius of curvature is the same as that of the spiral scraper. When the spiral scraper rotates, the scraper surface runs against the inner arc surface. The air outlet is horizontally installed on the side plate outside the arc of the filter screen.

[0010] The spiral scraper inside the air filtration device is designed in an S-shape with the same height as the plane. The spiral scraper and scraper shaft are installed on the frame of the air outlet at the top of the triangular cavity collection box. There are two sets of spiral scrapers arranged side by side. The driver of the spiral scraper is fixed on the outer box plate at the highest position of the bottom plate of the triangular cavity collection box. The driver of the spiral scraper is an AC geared motor. The driving wheel of the driver drives the two sets of driven scraper wheels through double belts.

[0011] The waste compression mechanism includes a compression head and a compression chamber, which is the space for compressing waste. It connects the waste inlet and the waste container, and plays a role in transition and compression. The compression head is shorter at the bottom and longer at the top. The total length of the compression chamber and the compression head is greater than the stroke of the drive. The external dimensions of the compression chamber and the compression head are smaller than the waste inlet. The detection element designed inside the waste compression mechanism is a pressure sensor.

[0012] The compression head has the same external dimensions as the compression chamber, the compression chamber is hollow, the drive arm is fixed inside the compression chamber, and a guide rail motion design is adopted. It adopts a horizontal direct pressure method, the gap between the compression head and the garbage inlet is small, the compression head and the compression chamber are reinforced by steel plates, the driver is a hydraulic cylinder, and the detection element for the stroke position of the hydraulic rod is a position sensor.

[0013] The horizontal direct pressure method is used to isolate the waste between the compression container and the compression host to prevent the waste from flowing back during the compression process. The gate is equipped with cutters on three sides. During the horizontal direct pressure process, the cutters can cut off the waste at the gate by recovering the pressure, thus preventing the waste from bouncing back.

[0014] The bottom of the garbage container is designed with pulleys, and the garbage container of the collection and separation device is placed on the ground with a track and a traction mechanism. The traction mechanism is driven by an AC geared motor. The garbage container and the garbage compression mechanism are designed with a locking mechanism, and the driver of the locking mechanism is a hydraulic cylinder.

[0015] This invention features a modular design for the waste collection and separation device. The air outlet and air filter are independently designed within an outwardly protruding structure. The filter structure has an inner arc shape, with its radius matching that of the rotating scraper. As the spiral scraper rotates, its surface runs along the inner arc, pushing the waste adhering to the filter towards the waste outlet. This reduces waste accumulation at the bottom of the collection box and facilitates the collection of waste from the box. Furthermore, the scraper shaft is mounted on the frame of the air outlet at the top of the triangular cavity collection box, which facilitates the production, assembly, and maintenance of the device after long-term operation.

[0016] To prevent waste from flowing back during compression, cutters are installed around the gate. During horizontal compression, the cutters cut the waste at the gate by recovering the pressure, thus preventing the waste from bouncing back. Attached Figure Description

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0023] See Figure 1 The garbage inlet 21 of the triangular cavity collection box 25 is designed at one end of the garbage outlet 23. The inlet pipe 211 of the garbage inlet 21 is bent inward at a downward angle. The outer pipe of the garbage inlet 21 is designed with an inlet flange 212. A garbage baffle 254 is installed directly in front of the pipe of the garbage inlet 21. The garbage baffle 254 is fixed to the upper box plate and the side box plate of the triangular cavity collection box 25, so as not to affect the air passage from the other side and the bottom.

[0024] See Figure 1The garbage outlet 23 is designed at the lowest position of the bottom plate 251 of the triangular cavity collection box 25. It is the intersection of the garbage gate 267 of the garbage container 29 with the compression head 262 and the compression chamber 268. The area of ​​the garbage outlet 23 is larger than the horizontal area of ​​the compression chamber 268. The garbage inlet 21 and the garbage outlet 23 are not in the same vertical position.

[0025] See Figure 2 , Figure 3 The air outlet 22 and the air filter device 221 are independently designed in an outwardly protruding structure. The filter screen structure 249 is in the shape of an inner arc, and its radius of curvature is the same as that of the spiral scraper 245. When the spiral scraper 245 rotates, the scraper surface runs against the inner arc surface. The air outlet 22 is horizontally installed on the side plate outside the arc of the filter screen.

[0026] See Figure 3 , Figure 4 The spiral scraper 245 inside the air filter device 221 is designed in an S-shape with the same height as the plane. The spiral scraper 245 and the scraper shaft 244 are installed on the frame of the air outlet 22 at the top of the triangular cavity collection box 25. There are two sets of spiral scrapers 245 arranged side by side. The driver of the spiral scraper 245 is fixed on the outer box plate at the highest position of the collection box bottom plate 251 of the triangular cavity collection box 25. The scraper driver 24 of the spiral scraper 245 is an AC geared motor. The drive wheel 241 of the scraper driver 24 is connected to the two sets of scraper driven wheels 243 through the double drive belt 248.

[0027] See Figure 1 The compression head 262 and compression chamber 268 of the garbage compression mechanism 26 are positioned on the compression chamber guide rail 264. The gate 267 is the feed inlet of the garbage container 29. The space of the compression section adopts the compression chamber guide wheel 263 guide rail motion design. The compression head 262 connects the garbage gate 267 and the garbage container 29, playing the role of transition and compression. The compression head 262 is shorter at the bottom and longer at the top, which is conducive to the downward compression of garbage. The total length of the compression chamber 268 and the compression head 262 is less than the stroke of the driver. When the compression chamber 268 retracts to the end, the compression head 262 retracts completely back into the outer body of the compression chamber driver 260, and the garbage on the garbage outlet 23 can enter the space of the compression section without obstruction.

[0028] See Figure 1 The compression head 262 and the compression chamber 268 adopt a horizontal direct pressure method. The gap between the compression head 262 and the garbage inlet is small. The compression head 262 and the compression chamber 268 are reinforced by steel plates. The compression chamber driver 260 is a hydraulic cylinder body. Two sensors are installed in the stroke of the hydraulic rod drive arm 261.

[0029] See Figure 2The horizontal direct pressure method is used to isolate the waste between the compression container and the compression host to prevent the waste from flowing back during the compression process. The gate 267 is equipped with cutters 266 on all three sides. During the horizontal direct pressure process, the cutters 266 can cut off the waste at the gate 267 through pressure to prevent the waste from rebounding.

[0030] See Figure 1 The bottom of the garbage container 29 is equipped with container rollers 292. The ground is designed with a traction mechanism 290 and a container track 291. The traction mechanism 290 is driven by an AC geared motor. The locking mechanism driver 27 of the garbage container 29 and the garbage compression mechanism is fixed in the frame of the garbage compression mechanism 26. The lever arm brake 272 of the locking lever arm 271 is positioned on the locking track plate under the garbage compression mechanism 26. The lever arm hook 273 can be attached to the outer structure of the garbage container 29 after the locking lever arm 271 is extended. The locking mechanism driver 27 is a hydraulic cylinder.

[0031] The compression head is a key component for compressing waste. Its compression method is usually horizontal direct pressure, which can compress waste from a loose state into a more compact state, reducing the volume of waste.

[0032] The compression head and compression chamber are designed with a guide rail, which minimizes the gap between them, ensures accurate positioning, reduces friction, and allows for smooth operation with minimal wear. The compression head and compression chamber are made of reinforced steel plates to ensure sufficient strength and durability, enabling continuous operation under harsh conditions.

[0033] The compression chamber is the space where waste is compressed. It connects the waste inlet and the waste container, and serves as a transition and compression mechanism.

[0034] The hydraulic locking device of the garbage compressor mainly consists of a hydraulic cylinder, a locking track plate, and a lever arm hook. It is used to lock the garbage compressor host and the garbage container body to ensure that the two are firmly connected during the compression process.

[0035] Waste anti-rebound technology: During the compression process, waste may rebound due to the release of compressive force, resulting in poor compression. To solve this problem, compression machinery usually adopts some special structural designs, such as the guillotine blade of the gate and the special shape of the compression head, to prevent waste rebound.

[0036] To improve the efficiency and accuracy of garbage compression, the electronic control system is the control center of the entire compressor. All actions are controlled by PLC programs, which can realize hydraulic system protection, automatic compression cycle, and automatic fault diagnosis. The garbage compressor is designed with pressure sensors, full-load alarms and other functions. When the garbage container is full, the pressure sensor will automatically detect and send a signal, the control system will automatically stop compression and prompt the staff to replace the container.

[0037] The air outlet and air filter are independently designed in an outwardly protruding structure. The filter structure is in the shape of an inner arc, and its radius of curvature is the same as that of the spiral scraper. When the spiral scraper rotates, the S-shaped scraper surface runs against the inner arc surface. The garbage stuck on the filter screen will be pushed off towards the garbage outlet by the spiral scraper, which reduces the accumulation of garbage at the bottom of the collection box and facilitates the collection of garbage from the box.
