Description

Technical Field

[0001] This invention belongs to the field of separation technology, and specifically provides a garden waste treatment system, monitoring method, and treatment method. Background Technology

[0002] Garden waste generally includes withered leaves, dead shrub branches, dry grass, and tree branches and leaves with high normal moisture content that garden maintenance personnel have actively pruned for aesthetic reasons. In other words, garden waste is likely to contain two categories of waste with significantly different moisture contents.

[0003] In the relevant technical solutions, the garden waste treatment system includes a wood shredder. The waste enters the shredder in a roughly funnel-shaped manner, covered by a dust suppression cover. During operation, the waste is crushed by the shredder's internal crushing rollers and then used as raw material for feed or biomass fuel. However, in actual use, the waste easily contains dried plant branches and fallen leaves with very low moisture content, causing this portion of the waste to generate dust after crushing, resulting in air pollution at the work site.

[0004] The inventor attempted to install a baghouse dust collector at the rear of the crusher, utilizing the filter bags to separate the gas from some of the dust and debris. However, this solution requires periodically stopping the baghouse dust collector to remove the accumulated debris and dust at the bottom. In other words, the baghouse dust collector is not suitable for continuous operation, affecting the crusher's efficiency in processing garden waste. Summary of the Invention

[0005] The purpose of this invention is to provide a garden waste treatment system that can at least solve one of the above-mentioned technical problems.

[0006] To address the aforementioned problems in the prior art, one or more embodiments of the present invention provide a garden waste treatment system, including a frame on which a crushing component and a bag assembly are mounted. The crushing component is used to crush waste. The inlet of the bag assembly is connected to the outlet of the crushing component, and the outlet of the bag assembly is connected to an air extraction device. The bag assembly includes a shell with an inner cavity. The cross-section of the inner cavity is circular. The inner cavity of the shell is divided into an upper cavity and a lower cavity by a circular horizontal plate. The upper cavity has an air outlet, and the lower cavity has a feed inlet. The lower end of the shell has a discharge outlet. The horizontal plate has multiple through holes along its circumference, and the through holes are arranged radially in multiple rows along the center of the horizontal plate. Filter cartridges are inserted into the through holes. The filter cartridges are equipped with electrically operated on / off valves at their installation ports. Vibrators are installed at the lower ends of the inner cavities of the filter cartridges.

[0007] A vertical baffle is rotatably mounted in the lower cavity. The axis of rotation of the baffle coincides with the central axis of the horizontal plate. The baffle has multiple slots to allow the filter cartridge to pass through when the baffle rotates. The baffle divides the lower cavity of the outer shell into a feeding space and a discharging space. The feeding space is connected to the discharge port, while the discharging space is not connected to the discharge port. The on / off valve of the filter cartridge is open in the feeding space and closed in the discharging space. The baffle can rotate to change the distribution range of the feeding and discharging spaces.

[0008] This invention also provides a monitoring method for a garden waste treatment system, comprising the following steps:

[0009] Step 1: Use the monitoring module to obtain gas flow data at each filter cartridge.

[0010] Step 2: Use the first comparison module to arrange the gas flow data of each filter cartridge in ascending order.

[0011] Step 3: Use the control module to select the gas flow rate data Q1 with the smallest value, and compare the value of Q1 with the preset minimum gas flow rate data Q in the second comparison module.

[0012] Step 4: If Q1 is greater than Q, then no cleaning command for the filter cartridge is issued; if Q1 is less than Q, then a cleaning command for the filter cartridge is issued.

[0013] This invention also provides a method for processing cleaning instructions in a garden waste disposal system, comprising the following steps:

[0014] Step 1: Determine if the control module has received a cleanup command; if it has, proceed to Step 2; otherwise, continue waiting.

[0015] Step 2: Use the third comparison module to select several filter cartridges on both sides of the filter cartridge with the smallest gas flow rate data, and form a selected range; the space occupied by the selected range is equal to the space of the discharge space.

[0016] Step 3: Drive the partition to rotate, so that the partition divides the lower cavity into corresponding discharge space and feed space. The filter cartridge in the discharge space is the same as the filter cartridge in the selected range.

[0017] Step 4: Control the vibrator at the filter cartridge in the discharge space to open and the on / off valve to close, so that the filter cartridge in the discharge space can discharge material.

[0018] The beneficial effects of one or more of the above technical solutions:

[0019] In this solution, a crushing component and a bag filter assembly are installed on the frame. The crushing component breaks down garden waste with varying moisture content, facilitating its compression and collection. To prevent dust and debris from low-moisture branches and fallen leaves from impacting the surrounding environment, the feed inlet of the bag filter assembly is connected to the outlet of the crushing component, and the air outlet of the bag filter assembly is connected to an extraction system. This allows for the removal of debris and dust from the crushing component using the bag filter assembly and extraction system, preventing this material from entering the subsequent recycling packaging boxes and bags. In other words, the output from the crushing component is primarily large-volume material, reducing the probability of dust generation during transportation and subsequent processing.

[0020] In addition, to facilitate continuous operation of the crushing component, this solution includes a rotating baffle in the lower chamber of the bag assembly. The baffle divides the lower chamber into a feeding space and a discharging space. The filter cartridges in the feeding space are ventilated, while those in the discharging space are not. The feeding space is connected to the inlet of the bag assembly, while the discharging space is not. The vibrator is activated. During operation, the rotation of the baffle allows any filter cartridge to switch between ventilated dust filtration and closed-loop dust discharge. In other words, this solution enables the discharge of filtered dust from the bag assembly without stopping the machine, thus improving the overall processing efficiency of the waste treatment equipment.

[0036] Example 1

[0037] like Figures 1-8As shown, this embodiment provides a garden waste treatment system, including a frame 4. A crushing component 2 and a bag assembly 23 are mounted on the frame 4. The crushing component 2 is used to crush waste. The inlet 8 of the bag assembly 23 is connected to the outlet of the crushing component 2, and the outlet 10 of the bag assembly 23 is connected to an air extraction device. The bag assembly 23 includes a shell 9 with an inner cavity. The cross-section of the inner cavity is circular. The inner cavity of the shell 9 is divided into an upper cavity and a lower cavity by a circular horizontal plate 22. The upper cavity has an air outlet 10, and the lower cavity has an inlet 8. The lower end of the shell 9 has an outlet 7. The horizontal plate 22 has multiple through holes 221 along its circumference, arranged radially in multiple rows along the center of the horizontal plate 22. Filter cartridges 18 are inserted into the through holes 221. Each filter cartridge 18 has an electrically operated on / off valve 182 at its installation port. Vibrators (not shown in the figure) are installed at the lower end of the inner cavity of the filter cartridge 18.

[0038] A vertical partition 21 is rotatably installed in the lower cavity. The rotation axis of the partition 21 coincides with the central axis of the horizontal plate 22. The partition 21 is provided with multiple slots 2103, which are used to avoid the filter cartridge 18 when the partition 21 rotates. The partition 21 can divide the lower cavity of the outer shell 9 into a feeding space 2101 and a discharging space 2102. The feeding space 2101 is connected to the discharge port 7, while the discharging space 2102 is not connected to the discharge port 7. The on / off valve 182 of the filter cartridge 18 in the feeding space 2101 is open, and the on / off valve 182 of the filter cartridge 18 in the discharging space 2102 is closed. The partition 21 can rotate to change the distribution range of the feeding space 2101 and the discharging space 2102.

[0039] Generally, garden waste includes both dried leaves and branches that have naturally fallen to the ground, as well as green leaves and branches with high water content that gardeners actively prune. The crushing, recycling, and reuse of waste such as withered leaves easily generate a lot of debris and dust, which can easily cause environmental pollution at the work site.

[0040] In this embodiment, the outlet of the crushing component 2 is used to discharge the crushed material, while the inlet 8 of the bag assembly 23 is not directly connected to the outlet of the crushing component 2, and the bag assembly 23 does not obstruct the normal discharge of the crushing component 2. Specifically, a connecting port 3 is provided on the shell of the crushing component 2. The connecting port 3 is higher than the outlet of the crushing component 2. During the process of the crushed material moving towards the outlet under gravity, the fragments and dust in the material will pass through the connecting port 3 and be attracted into the bag assembly 23 by the negative pressure at the connecting port 3.

[0041] Specifically, the frame 4 here is the chassis of the mobile trolley, and the lower part of the trolley is equipped with a wheeled or tracked walking mechanism 5. Taking the tracked trolley 5 as an example, drive wheels 6 are installed on the front and rear sides of the frame 4, and tracks 5 are fitted over the drive wheels 6. An upwardly inclined handrail 1 is installed on the rear side of the frame 4, and the top of the handrail 1 forms a handle, which the user can use to control the forward and backward direction of the entire trolley. A mounting base 13 is formed on the top of the frame 4, which is used to support and fix the crushing component 2 and the bag assembly 23.

[0042] As one specific structural form, see Figure 1 The crushing component 2 is a wood crusher, and the bag filter assembly 23 is a bag dust collector. The crushing component 2 is installed on the rear side of the mounting base 13 near the handle 1, and the bag filter assembly 23 is installed on the front side of the mounting base 13 via a bracket 19. The feed inlet 8 of the bag filter assembly 23 and the connecting port 3 of the crushing component 2 are located on the same side of the frame 4, facilitating communication between them via an air pipe 11. Furthermore, the crushed material outlet of the crushing component 2 is located on the other side of the crushing component 2. Collection bags are installed at the discharge port 7 at the lower end of the bag filter assembly 23 and the material outlet of the crushing component 2, respectively, to collect the crushed waste discharged from the crushing component 2 and the fragments and dust discharged from the bag filter assembly 23.

[0043] In this embodiment, the outer shell 9 of the filter bag assembly 23 includes an upper shell and a lower shell, which are spliced ​​together to enclose the inner cavity of the outer shell 9. Specifically, the upper shell is cylindrical and the lower shell is conical, with the diameter of the upper shell equal to the diameter of the larger end of the lower shell. The upper and lower shells can be manufactured as a single piece or separately and then welded together. Specifically, the upper shell has a removable cover plate 16 at its upper end, which is fixed to the upper end of the upper shell by bolts or clips. When the cover plate 16 is removed, the internal space of the upper shell can be exposed to facilitate the disassembly and assembly of the filter cartridge 18.

[0044] For details, see Figure 3 The partition 21 is installed on the upper part of the upper shell. The distance between the partition 21 and the top of the upper shell is H1, and the distance between the partition 21 and the bottom of the upper shell is H2, where H1 is less than H2. That is to say, the upper half of the internal space of the upper shell forms the upper cavity, and the lower half of the internal space of the upper shell and the internal space of the lower shell form the lower cavity. At this time, the air outlet 10 of the upper cavity is located in the upper shell, and the feed inlet 8 of the lower cavity can be located in either the lower shell or the upper shell.

[0045] See Figures 6-8Here, the horizontal plate 22 is a circular plate, with its central axis vertically oriented. Multiple rings of through holes 221 are vertically arranged around the central axis of the horizontal plate 22, with each ring containing multiple through holes 221 evenly distributed circumferentially around the horizontal plate 22. The through holes 221 in the multiple rings are arranged radially, for example... Figure 6 and Figure 7 The diagram shows four or eight rows of through holes 221. In other embodiments, the through holes 221 can also be set to twelve or sixteen rows, or other numbers, which can be determined by those skilled in the art. As a complement, multiple slots 2103 are arranged sequentially along the transverse direction of the partition 21. When the partition 21 rotates, the rows of filter cartridges 18 can be simultaneously inserted into the slots 2103 of the partition 21, thereby sealing the slots 2103 and preventing the slots 2103 from directly connecting the feed space 2101 and the discharge space 2102.

[0046] Specifically, the filter cartridge 18 is inserted into the through hole 221. The outer diameter of the filter cartridge 18 is equal to the inner diameter of the through hole 221, thus preventing air leakage due to gaps. This ensures that the gas carrying dust and debris must be filtered by the filter cartridge 18 before being discharged from the outlet 10. The upper end of the filter cartridge 18 extends into the upper cavity, and the lower end of the filter cartridge 18 is located in the lower cavity. The length of the filter cartridge 18 in the upper cavity is much shorter than its length in the lower cavity, so that the dust filtration operation can be carried out using the partial structure of the filter cartridge 18 in the lower cavity.

[0047] In this embodiment, because the lower end of the filter cartridge 18 extends into the lower cavity, the conical lower shell participates in forming the lower cavity. To fully utilize the conical space structure of the lower cavity, the filter cartridges 18 are arranged in an unequal length configuration. That is, the filter cartridges 18 located at the circumferential edge of the outer shell 9 are shorter, while the filter cartridges 18 closer to the circumferential center of the outer shell 9 are longer. See [link to specific structural form] for details. Figure 4 Each row of filter cartridges 18 contains four cartridges, with the outermost cartridge 18 being shorter than the three inner cartridges 18. The three inner cartridges 18 are of the same length. In other structural configurations, the multiple filter cartridges 18 arranged in a row are progressively longer in a stepped manner along the direction close to the center of the outer shell 9.

[0048] Specifically, a controller is provided here. The controller independently controls the on / off state of different on / off valves 182 through a relay module, and the controller can also control the rotation and positioning of the partition 21.

[0049] In this embodiment, the slot 2103 penetrates the horizontal plate 22 along its thickness direction and extends through the upper end face of the horizontal plate 22. A cleaning brush is provided on the inner wall of the slot 2103. (See also...) Figures 3-5To accommodate the shape of the lower cavity, the partition 21 here includes a square upper half and a roughly triangular lower half. The side of the upper half of the partition 21 fits against the inner wall of the upper shell, and the side of the lower half fits against the inner wall of the lower shell. Similarly, to accommodate different lengths of the filter cartridge 18, the groove 2103 here is shorter on the outer side and longer on the inner side.

[0050] In this embodiment, the top surface of the partition 21 is attached to the lower surface of the horizontal plate 22, and the side surface of the partition 21 is attached to the inner wall of the outer shell 9.

[0051] Specifically, in order to achieve the separation effect of the partition 21 on the lower cavity and prevent the feeding space 2101 and the discharging space 2102 from communicating through the gap between the inner wall of the lower cavity and the partition 21, elastic sealing gaskets are respectively provided on the side and top edge of the partition 21. The sealing gaskets here can be silicone gaskets or rubber gaskets, which can be designed by those skilled in the art.

[0052] In this embodiment, the partition 21 includes two plates arranged at an angle, the angle of which can be adjusted and fixed to change the ratio of the discharge space 2102 and the feed space 2101. The partition 21 is rotatably connected to the horizontal plate 22 via a rotating shaft 20, and the partition 21 is fixed to the rotating shaft 20, which is driven by a rotation drive assembly provided on the horizontal plate 22.

[0053] When the partition 21 is a single flat plate, a shaft hole is provided at the vertical center of the partition 21, and a rotating shaft 20 is fixedly inserted through the shaft hole. The lower end of the rotating shaft 20 is flush with the lower end of the partition 21, and the upper end of the rotating shaft 20 extends out of the upper end of the partition 21. The upper end of the rotating shaft 20 passes upward through the horizontal plate 22 and connects to the rotary drive assembly. The rotary drive assembly here can be a drive motor 17. The housing of the drive motor 17 is supported by the upper surface of the horizontal plate 22. The output shaft of the drive motor 17 is positioned downward, and the output shaft is coaxially fixed to the rotating shaft 20 via a coupling. In other embodiments, the rotary drive assembly can be a pneumatic motor, which can be configured by those skilled in the art.

[0054] In other embodiments, the lower end of the rotating shaft 20 extends downward through the partition 21, and the rotating shaft 20 is fixed inside the shaft hole of the partition 21. The lower end of the rotating shaft 20 is fixed to a support ring rotatably mounted at the discharge port 7 of the lower shell via spokes. In this case, the support ring can receive power from the rotary motor through a gear mechanism or a sprocket mechanism, and the support ring can drive the rotating shaft 20 and the partition 21 to rotate synchronously through the spokes. That is to say, through the support ring and spoke structure, the power drive component for the rotation of the partition 21 can be installed at the lower end of the outer shell 9, so as to lower the center of gravity of the entire device.

[0055] For details, see Figure 7 or Figure 8 The partition 21 consists of two plates, namely the first plate 211 and the second plate 212 shown in the figure. The first plate 211 and the second plate 212 are supported and fixed by the rotating shaft 20, but the included angle between the first plate 211 and the second plate 212 can be adjusted, thereby allowing the size ratio of the feeding space 2101 and the discharging space separated by the partition 21 to be adjusted.

[0056] By adjusting the size of the feeding space 2101 and the discharging space, it is possible to adapt to different application scenarios with varying contents of fragments and dust after waste crushing. For example, in applications with higher temperatures, such as in summer or in southern regions, the waste contains more moisture, such as branches and leaves, resulting in less fragments that easily generate dust after crushing. Consequently, the bag filter assembly does not need to frequently discharge the fragments separated in the lower chamber. In this case, the volume of the feeding space 2101 can be larger than the volume of the discharging space 2102. Conversely, in applications with lower temperatures, such as in winter or in northern regions, there is more fragments that easily generate dust after waste crushing. In this case, the volume of the feeding space 2101 can be smaller than the volume of the discharging space 2102, allowing the bag filter assembly 23 to fully discharge the absorbed fragments and preventing clogging.

[0057] Specifically, to connect the partition plate to the rotating shaft 20, an external thread is provided on the rotating shaft 20, and the partition plate has a vertical threaded hole. The partition plate and the rotating shaft 20 are connected through the external thread and the threaded hole. More specifically, the first partition plate 211 has a groove, and the second partition plate 212 has a protrusion. The vertical projection of the threaded hole passes through the groove and the protrusion respectively. This arrangement allows for positional avoidance when both partition plates are connected to the rotating shaft 20 simultaneously.

[0058] In this embodiment, the rotary drive assembly is supported by the lifting assembly. The lifting drive assembly can drive the rotary drive assembly, the rotating shaft 20 and the partition 21 to move up and down synchronously. The upper end of the partition 21 is made of elastic material.

[0059] Specifically, the lifting drive assembly here can be an electric push rod, a cylinder, or a hydraulic push rod. When the lifting assembly is in motion, the partition 21 scrapes the filter cartridge 18 vertically, making it easier to clean the debris and dirt accumulated on the outer wall of the filter cartridge 18 using the slot 2103 of the partition 21.

[0060] In this embodiment, the filter cartridge 18 includes a first cylinder 181 and a second cylinder 183. The first cylinder 181 and the second cylinder 183 are connected by an on / off valve 182. The first cylinder 181 includes a cylindrical frame and a cloth bag. The upper end of the cloth bag is open, and the cylindrical frame is inserted into the inner cavity of the cloth bag to open the cloth bag.

[0061] Specifically, both the first cylinder 181 and the second cylinder 183 are cylindrical. The upper end of the first cylinder 181 is connected to the lower port of the on-off valve 182, and the lower end of the second cylinder 183 is connected to the upper port of the on-off valve 182. The electrically operated on-off valve 182 can be controlled by the aforementioned controller to achieve the on / off switching of the filter cartridge 18. More specifically, the on-off valve 182 is blocked at the aforementioned through hole 221.

[0062] In this embodiment, a vertically arranged cyclone separator is also included. The lower opening of the cyclone separator is provided with an openable and closable baffle. The cyclone separator is connected in series between the bag assembly 23 and the air extraction device.

[0063] Specifically, the aforementioned cyclone separator structure further processes the gas discharged from the bag filter assembly 23, reducing dust emissions. The gas inlet of the cyclone separator is connected to the gas outlet of the bag filter assembly 23, and the gas outlet of the cyclone separator is connected to the inlet of an extraction device. This extraction device can be a fan.

[0064] In this embodiment, the crusher includes a shell, the interior of which forms a crushing space. A pair of crushing rollers 14 are installed in the crushing space. The upper part of the shell is connected to a hopper for easy feeding. Garden waste descends from top to bottom and enters the crushing rollers 14 through the funnel 12. The crushing rollers 14 crush the waste. The crushed material falls downwards onto the collecting ramp 15 at the bottom of the shell, and then is discharged inclined downwards from the crusher's outlet. As the material moves downwards from the crushing rollers 14, the fragmented material moves from the connecting port 3 to the bag filter assembly 23 for separation and filtration. To prevent dust from forming at the funnel 12, a removable dust suppression cover can be installed at the top of the funnel 12.

[0065] Working principle: When using this device, garden waste is collected and fed into the crusher. The crushing roller 14 crushes the waste and discharges it downwards to the outlet. When the crushed waste passes through the connecting port 3 on the crusher housing, there is a certain negative pressure at the connecting port 3. The strength of this negative pressure is set such that the fragments in the crushed material are drawn to the bag assembly 23, but the heavier crushed material of normal particle size cannot be attracted. The larger crushed material will still fall to the crusher outlet and be packaged and transported in packaging bags.

[0066] The bag assembly 23 is evacuated by the extraction equipment. In the initial stage, all the on / off valves 182 of the filter cartridges 18 are open, and the gas flows out of the filter cartridges 18. The debris is blocked on the outer wall of the filter cartridges 18, thus leaving the debris and dust in the bag assembly 23. After working for a period of time, the control baffle 21 is rotated at an angle, so that part of the original discharge space 2102 becomes the feed space 2101, and part of the original feed space 2101 becomes the discharge space 2102. The on / off valves 182 in the discharge space 2102 are closed, so that the discharge space 2102 loses gas attraction. Then the vibrator in the discharge space 2102 is activated, and the debris accumulated at this position will fall to the discharge port 7 at the lower end of the lower shell.

[0067] Every so often, the baffle 21 is rotated at a certain angle to sequentially discharge the debris from different positions of the filter cartridge 18.

[0068] Example 2

[0069] like Figures 9-10 As shown, this embodiment provides a monitoring method for a garden waste treatment system, used to monitor the treatment system in Embodiment 1 above, including the following steps:

[0070] Step 1: Use the monitoring module to obtain gas flow data at each filter cartridge.
