Description

Technical Field

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

[0002] Garden waste generally includes dead leaves, dead branches of bushes, dry grass leaves, and some tree branches and leaves with high water content that are actively pruned by garden maintenance personnel for aesthetic reasons. That is, there are two types of waste with large differences in water content in garden waste.

[0003] In the relevant technical solution, the garden waste treatment system includes a wood crusher. The waste is roughly funnel-shaped from the inlet of the crusher, and the inlet is covered with a dust suppression cover. When in use, the waste is crushed by the crushing roller inside the crusher, and then used as raw materials for feed or biomass fuel. However, in actual use, the waste is easily mixed with dry plant branches and fallen leaves with very low water content, causing this part of the waste to easily form dust after crushing, causing air pollution in the work site.

[0004] The inventor tried to install a bag filter at the rear of the crusher, and use the bags in the bag filter to separate the gas and some dust fragments. However, this solution requires stopping the bag filter at regular intervals to remove the fragments and dust accumulated at the bottom of the bag filter. That is, the bag filter is not easy to operate without stopping the machine, which affects the efficiency of the crusher in processing garden waste. Summary of the invention

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

[0006] In order to solve the above-mentioned 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 assembly and a bag assembly are installed, the crushing assembly is used to crush the waste, the feed port of the bag assembly is connected to the outlet position of the crushing assembly, the air outlet of the bag assembly is connected to the exhaust device, the bag assembly includes an outer shell with an inner cavity, the cross-section of the inner cavity is circular, the inner cavity of the outer shell is divided into an upper cavity and a lower cavity by a circular horizontal plate, the upper cavity is provided with an air outlet, the lower cavity is provided with a feed port, the lower end of the outer shell is provided with a discharge port, the horizontal plate is provided with a plurality of circles of through holes along its circumference, the through holes are radially arranged in multiple rows along the center of the horizontal plate, a filter cartridge is inserted in the through hole, the filter cartridge is provided with an electric on-off valve at the installation port, and a vibrator is respectively installed at the lower end of the inner cavity of the filter cartridge.

[0007] A vertical partition is rotatably installed in the lower chamber, the rotation axis of the partition coincides with the central axis of the horizontal plate, and a plurality of notches are provided on the partition, which are used to avoid the filter cartridge when the partition rotates. The partition can separate the lower chamber of the housing into a feed space and a discharge space, the feed space is connected to the discharge port, and the discharge space is not connected to the discharge port, the on-off valve of the filter cartridge in the feed space is opened, and the on-off valve of the filter cartridge in the discharge space is closed, and the partition can rotate to change the distribution range of the feed space and the discharge space.

[0008] The present invention also provides a monitoring method for a garden waste treatment system, comprising the following steps: Step 1: Use the monitoring module to obtain the gas flow data at each filter cartridge.

[0009] Step 2: Use the first comparison module to arrange the gas flow data of each filter cartridge in order from small to large.

[0010] Step 3: Use the control module to select the gas flow data Q1 with the smallest value, and compare the value of Q1 with the lowest gas flow data Q preset in the second comparison module.

[0011] Step 4: If Q1 is greater than Q, no instruction to clean the filter cartridge is issued; if Q1 is less than Q, a cleaning instruction to clean the filter cartridge is issued.

[0012] The present invention also provides a method for processing a cleaning instruction of a garden waste treatment system, comprising the following steps: Step 1, determine whether the control module obtains a cleaning instruction; if a cleaning instruction is obtained, execute step 2, otherwise continue to wait.

[0013] Step 2, using the third comparison module to select a number of filter cartridges on both sides of the filter cartridge with the smallest gas flow data, and form a selected range; the space occupied by the selected range is equal to the space size of the discharge space.

[0014] Step 3: Drive the partition to rotate so that the partition separates the corresponding discharge space and feed space in the lower chamber. The filter cartridge in the discharge space is the same as the filter cartridge in the selected range. Step 4, controlling the rapper 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 is discharged.

[0015] Beneficial effects of one or more of the above technical solutions: In this solution, a crushing component and a bag component are installed on the frame, and the crushing component can be used to crush garden waste with different water contents, so as to facilitate their compression and collection. In this process, in order to prevent the debris and dust formed by dead branches and fallen leaves with low water content from affecting the surrounding environment, this solution connects the feed port of the bag component with the outlet position of the crushing component, and the air outlet of the bag component is connected to the exhaust device. At this time, it is convenient to use the bag component and the exhaust device to suck out the debris and dust in the crushing component, thereby preventing this part of the material from entering the packaging boxes and packaging bags for subsequent recycling. That is, the output from the crushing component is basically large-volume materials, which reduces the probability of generating dust during transportation and subsequent processing.

[0016] In addition, in order to facilitate the continuous operation of the crushing assembly in this solution, a rotatable partition is provided in the lower chamber of the bag assembly, and the partition divides the lower chamber into a feed space and a discharge space. The filter cartridge in the feed space is ventilated, and the filter cartridge in the discharge space is not ventilated. At the same time, the feed space is connected to the feed port of the bag assembly, and the discharge space is not connected to the feed port of the bag assembly, and the vibrator is turned on. When in use, the rotation of the partition can be used to change any filter cartridge between ventilation dust filtration and wind-off dust discharge in turn. In other words, this solution can achieve the discharge of the dust and debris filtered in the bag assembly without stopping the bag assembly, which is convenient for improving the treatment efficiency of the entire waste treatment equipment.

For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0028] Example 1 like Figure 1-Figure 8As shown, a garden waste treatment system provided in this embodiment includes a frame 4, on which a crushing assembly 2 and a bag assembly 23 are installed. The crushing assembly 2 is used to crush waste. The feed port 8 of the bag assembly 23 is connected to the outlet position of the crushing assembly 2, and the air outlet 10 of the bag assembly 23 is connected to the exhaust device. The bag assembly 23 includes a shell 9 with an inner cavity, the cross section of the inner cavity is circular, and the inner cavity of the shell 9 is divided into an upper cavity and a lower cavity by a circular cross plate 22. The upper cavity is provided with an air outlet 10, and the lower cavity is provided with a feed port 8. The lower end of the shell 9 has a discharge port 7, and the cross plate 22 is provided with a plurality of circles of through holes 221 along its own circumference, and the through holes 221 are arranged in multiple rows radially along the center of the cross plate 22. A filter cartridge 18 is inserted in the through hole 221, and the filter cartridge 18 is provided with an electric on-off valve 182 at the installation port. The lower ends of the inner cavity of the filter cartridge 18 are respectively installed with vibrators (not shown in the figure).

[0029] A vertical partition 21 is rotatably installed in the lower chamber, the rotation axis of the partition 21 coincides with the central axis of the horizontal plate 22, and a plurality of notches 2103 are provided on the partition 21, and the notches 2103 are used to avoid the filter cartridge 18 when the partition 21 rotates. The partition 21 can separate the lower chamber of the housing 9 into a feed space 2101 and a discharge space 2102, the feed space 2101 is connected to the discharge port 7, and the discharge space 2102 is not connected to the discharge port 7, the on-off valve 182 of the filter cartridge 18 in the feed space 2101 is opened, and the on-off valve 182 of the filter cartridge 18 in the discharge space 2102 is closed, and the partition 21 can rotate to change the distribution range of the feed space 2101 and the discharge space 2102.

[0030] Generally, garden waste includes both dried leaves and branches that naturally fall to the ground, and green leaves and branches with high water content that are actively pruned by gardeners. For waste such as withered leaves, it is easy to generate a lot of debris and dust during the process of crushing, recycling and reuse, which can easily cause environmental pollution in the workplace.

[0031] In this embodiment, the outlet of the crushing assembly 2 is used to discharge the crushed material, and the feed port 8 of the bag assembly 23 is not directly connected to the outlet of the crushing assembly 2, and the bag assembly 23 does not hinder the normal discharge of the crushing assembly 2. Specifically, a connecting port 3 is provided on the shell of the crushing assembly 2. The connecting port 3 is higher than the outlet of the crushing assembly 2. When the crushed material moves toward the outlet under gravity, the fragments and dust in the material will pass through the connecting port 3 and be attracted by the negative pressure at the connecting port 3 and enter the bag assembly 23.

[0032] Specifically, the frame 4 here is the frame of a mobile trolley, and the lower part of the trolley is provided with a wheeled or tracked 5 type walking mechanism. Taking the tracked 5 type trolley as an example, the front and rear sides of the frame 4 are respectively provided with driving wheels 6, and the outer cover of the driving wheels 6 is provided with a track 5. An upwardly inclined handrail 1 is installed on the rear side of the frame 4, and a handle is formed at the top of the handrail 1. The user can control the forward and backward direction of the entire trolley by holding the handle. A mounting seat 13 is formed above the frame 4 here, and the mounting seat 13 is used to support and fix the crushing assembly 2 and the bag assembly 23.

[0033] As one of the specific structural forms, see Figure 1 , the crushing component 2 is a wood crusher, and the bag component 23 is a bag dust collector. The crushing component 2 is installed on the rear side of the mounting seat 13 near the handrail 1, and the bag component 23 is installed on the front side of the mounting seat 13 through the bracket 19. The feed port 8 of the bag component 23 and the connecting port 3 of the crushing component 2 are on the same side of the frame 4, so that the two can be connected by the air pipe 11. In addition, the crushed material outlet of the crushing component 2 is arranged on the other side of the crushing component 2, and the discharge port 7 at the lower end of the bag component 23 and the material outlet of the crushing component 2 are respectively installed with storage bags to respectively recover the crushed waste discharged from the crushing component 2 and the debris and dust discharged from the bag component 23.

[0034] In this embodiment, the outer shell 9 of the cloth bag assembly 23 includes an upper shell and a lower shell, and the upper shell and the lower shell are spliced ​​with each other to enclose the inner cavity of the outer shell 9. Specifically, the upper shell is cylindrical, and the lower shell is conical, and the diameter of the upper shell is equal to the diameter of the larger end of the lower shell. Here, the upper shell and the lower shell can be made in an integral molding manner, or they can be made in a manner of being welded and fixed after being made separately. Specifically, the upper end of the upper shell has a detachable cover plate 16, and the cover plate 16 is fixed to the upper end of the upper shell by bolts or snap-on connections. 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.

[0035] For details, see Figure 3 Here, 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 lower end of the upper shell is H2, where H1 is smaller than H2. In other words, the upper half of the internal space of the upper shell forms an upper cavity, and the lower half of the internal space of the upper shell and the internal space of the lower shell form a lower cavity. At this time, the air outlet 10 of the upper cavity is set on the upper shell, and the feed port 8 of the lower cavity can be set on the lower shell or the upper shell.

[0036] See also Figure 6-Figure 8Here, the horizontal plate 22 is a circular plate, and the central axis of the horizontal plate 22 is arranged vertically. Multiple circles of through holes 221 are arranged vertically around the central axis of the horizontal plate 22, and the multiple through holes 221 of each circle are evenly distributed around the circumference of the horizontal plate 22. The through holes 221 in the multiple circles of through holes 221 are arranged radially, for example Figure 6 and Figure 7 In some other embodiments, the through holes 221 may be set to other numbers such as twelve or sixteen, which can be set by those skilled in the art. In coordination, a plurality of notches 2103 are sequentially arranged along the lateral direction of the partition 21. When the partition 21 rotates, the filter cartridges 18 in a row can be synchronously inserted into the notches 2103 of the partition 21, thereby achieving the blocking of the notches 2103 and preventing the notches 2103 from causing the feed space 2101 and the discharge space 2102 to be directly connected.

[0037] Specifically, the filter cartridge 18 is inserted into the through hole 221, and the outer diameter of the filter cartridge 18 is equal to the inner diameter of the through hole 221, so that there is no air leakage due to the gap between the two, so that the gas carrying debris and dust must be filtered by the filter cartridge 18 before it can be discharged from the air outlet 10. The upper end of the filter cartridge 18 extends to the upper cavity, and the lower end of the filter cartridge 18 is in the lower cavity. The length of the filter cartridge 18 in the upper cavity is much smaller than its length in the lower cavity, so that the partial structure of the filter cartridge 18 in the lower cavity can be used for dust filtering.

[0038] In this embodiment, because the lower end of the filter cartridge 18 extends into the lower cavity, and the conical lower shell participates in forming the lower cavity. In order to fully utilize the conical space structure of the lower cavity, the filter cartridge 18 is arranged in unequal lengths. That is, the filter cartridge 18 at the circumferential edge of the outer shell 9 is shorter, while the filter cartridge 18 near the circumferential center of the outer shell 9 is longer. As a specific structural form, see Figure 4 , the number of filter cartridges 18 in each row is four, and the length of the outermost filter cartridge 18 is less than the length of the three inner filter cartridges 18. The lengths of the three inner filter cartridges 18 are the same. In some other structural arrangements, the multiple filter cartridges 18 arranged in a row are gradually lengthened in a step-like manner along the direction close to the center of the housing 9.

[0039] Specifically, a controller is provided here, and the controller independently controls the on and off of different on-off valves 182 through a relay module, and the controller can control the rotation and positioning of the partition 21.

[0040] In this embodiment, the notch 2103 penetrates the transverse plate 22 along the thickness direction of the transverse plate 22, the notch 2103 penetrates the upper end surface of the transverse plate 22, and a cleaning brush is provided on the inner wall surface of the notch 2103. Figure 3-Figure 5In order to adapt to the shape of the lower chamber, the partition 21 here includes a square upper part and a roughly triangular lower part. The side of the upper part of the partition 21 fits with the inner wall of the upper shell, and the side of the lower part of the partition 21 fits with the inner wall of the lower shell. Similarly, in order to adapt to the different lengths of the above-mentioned filter cartridge 18, the length of the slot 2103 here is also shorter on the outside and longer on the inside.

[0041] In this embodiment, the top surface of the partition plate 21 is in contact with the lower surface of the horizontal plate 22 , and the side surface of the partition plate 21 is in contact with the inner wall of the outer shell 9 .

[0042] Specifically, in order to achieve the partition effect of the partition 21 on the lower chamber and prevent the feed space 2101 and the discharge space 2102 from being connected through the gap between the inner wall of the lower chamber and the partition 21: elastic sealing pads are respectively provided on the side and top of the partition 21. The sealing pads here can be silicone pads or rubber pads, which can be provided by technicians in this field.

[0043] In this embodiment, the partition 21 includes two partitions arranged at an angle, and the angle between the two partitions 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 transverse plate 22 via a rotating shaft 20, the partition 21 is fixed to the rotating shaft 20, and the rotating shaft 20 is driven by a rotating drive assembly arranged on the transverse plate 22.

[0044] When the partition 21 is a whole flat plate, an axial hole is provided in the vertical center of the partition 21, and a rotating shaft 20 is fixedly passed through the axial 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 passes through the upper end of the partition 21. And the upper end of the rotating shaft 20 passes through the cross plate 22 upward and is connected to the rotating drive assembly. The rotating drive assembly here can adopt a driving motor 17, the casing of the driving motor 17 is supported by the upper surface of the cross plate 22, the output shaft of the driving motor 17 is arranged downward, and the output shaft and the rotating shaft 20 are coaxially fixed by a coupling. In some other embodiments, the rotating drive assembly can adopt a pneumatic motor, which can be set by those skilled in the art.

[0045] In some other embodiments, the lower end of the rotating shaft 20 passes through the partition 21 downward, 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 the support ring rotatably installed at the discharge port 7 of the lower shell through spokes. At this time, the support ring can receive the power of the rotating 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. In other words, through the support ring and the spoke structure, the power drive component when the partition 21 rotates can be installed at the lower end of the shell 9, so as to lower the center of gravity of the entire device.

[0046] For details, see Figure 7 or Figure 8 The partition 21 is composed of two sub-plates, namely the first sub-plate 211 and the second sub-plate 212 shown in the figure. The first sub-plate 211 and the second sub-plate 212 are respectively supported and fixed by the rotating shaft 20, but the angle between the first sub-plate 211 and the second sub-plate 212 can be adjusted, so that the size ratio of the feeding space 2101 and the discharging space separated by the partition 21 can be adjusted.

[0047] By adjusting the size of the feed space 2101 and the discharge space, it is possible to easily adapt to different situations in which the content of debris and dust after the waste is crushed in different application scenarios. For example, in applications with higher temperatures such as summer or in the south, the water content of branches and leaves in the waste is higher, and there are fewer debris that are easy to form dust after the waste is crushed, and then the bag dust removal assembly does not need to frequently discharge the debris separated in the lower chamber. At this time, the volume of the feed space 2101 can be made larger than the volume of the discharge space 2102. On the contrary, in applications with lower temperatures such as winter or in the north, there are more debris that are easy to form dust after the waste is crushed. At this time, the volume of the feed space 2101 can be made smaller than the volume of the discharge space 2102, so that the bag assembly 23 can fully discharge the debris it absorbs and avoid clogging of the bag assembly 23.

[0048] Specifically, in order to achieve the connection between the split plate and the rotating shaft 20, an external thread is provided on the rotating shaft 20, the split plate has a vertical screw hole, and the split plate and the rotating shaft 20 are connected through the external thread and the screw hole. More specifically, the first split plate 211 has a groove, and the second split plate 212 has a protrusion, and the vertical projection of the screw hole passes through the groove and the protrusion respectively. This arrangement can achieve position avoidance when the two split plates are connected to the rotating shaft 20 at the same time.

[0049] In this embodiment, the rotary drive assembly is supported by the lifting assembly, and the lifting drive assembly can drive the rotary drive assembly, the rotating shaft 20 and the partition 21 to rise and fall synchronously, and the upper end of the partition 21 is made of elastic material.

[0050] Specifically, the lifting drive assembly here can adopt 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, so that the notch 2103 of the partition 21 can be used to clean the debris accumulated on the outer wall of the filter cartridge 18.

[0051] In this embodiment, the filter cartridge 18 includes a first cylinder 181 and a second cylinder 183, which are connected via 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.

[0052] Specifically, the first cylinder 181 and the second cylinder 183 are both cylinders, the upper end of the first cylinder 181 is communicated with the lower end of the on-off valve 182, and the lower end of the second cylinder 183 is communicated with the upper end of the on-off valve 182. The electric on-off valve 182 can be controlled by the above-mentioned controller to realize the on-off of the filter cartridge 18. More specifically, the on-off valve 182 is blocked at the above-mentioned through hole 221.

[0053] In this embodiment, a vertically arranged cyclone separator is also included. The lower end opening of the cyclone separator is provided with an openable and closable baffle door. The cyclone separator is arranged in series between the bag assembly 23 and the air extraction device.

[0054] Specifically, the structural setting of the cyclone separator can further process the gas discharged from the bag assembly 23 to reduce the discharge of dust. The gas inlet of the cyclone separator is connected to the gas outlet of the bag assembly 23, and the gas outlet of the cyclone separator is connected to the inlet of the exhaust device. The exhaust device here can be a fan.

[0055] In this embodiment, the crusher includes a shell, and a crushing space is formed inside the shell. A pair of crushing rollers 14 are installed in the crushing space, and the upper part of the shell is connected to the hopper for feeding. Garden waste from top to bottom enters the crushing roller 14 position from the funnel 12, and the crushing roller 14 crushes the waste. The crushed material falls downward onto the aggregate slope 15 at the bottom of the shell, and then the material is discharged from the outlet of the crusher at an angle downward. In the process of the material moving downward from the crushing roller 14, the crushed material moves from the connecting port 3 to the bag assembly 23 for separation and filtration. In order to avoid the formation of dust at the funnel 12 position, a detachable dust suppression cover can be installed at the top of the funnel 12.

[0056] Working principle: When the device is used, the garden waste is collected and sent to the crusher, and the crushing roller 14 crushes the waste and discharges it downward to the outlet. When the crushed waste passes through the connecting port 3 on the crusher shell, there is a certain negative pressure at the connecting port 3. The strength of the negative pressure is set to be able to suck the crushed material into the bag assembly 23, but cannot attract the heavier crushed material of normal particle size. The larger crushed material will still fall to the crusher outlet and be packaged and transported in a packaging bag.

[0057] The bag assembly 23 is evacuated by the vacuum device. In the initial stage, the on-off valves 182 of all the filter cartridges 18 are in an open state, the gas flows out of the filter cartridge 18, and the debris is blocked on the outer wall of the filter cartridge 18, so that the debris and dust are left in the bag assembly 23. After working for a period of time, the partition 21 is controlled to rotate 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. Close the on-off valve 182 in the discharge space 2102, so that the discharge space 2102 loses gas suction, and then start the rapper in the discharge space 2102, and the debris accumulated at this position will fall to the discharge port 7 at the lower end of the lower shell.

[0058] At regular intervals, the partition 21 is rotated by a certain angle to discharge the debris from different positions of the filter cartridge 18 in sequence.

[0059] Example 2 like Figure 9-10 As shown, this embodiment provides a monitoring method for a garden waste treatment system, which is used to monitor the treatment system in the above embodiment 1, and includes the following steps: Step 1: Use the monitoring module to obtain the gas flow data at each filter cartridge.

[0060] Step 2: Use the first comparison module to arrange the gas flow data of each filter cartridge in order from small to large.

[0061] Step 3: Use the control module to select the gas flow data Q1 with the smallest value, and compare the value of Q1 with the lowest gas flow data Q preset in the second comparison module.

[0062] Step 4: If Q1 is greater than Q, no instruction to clean the filter cartridge is issued; if Q1 is less than Q, a cleaning instruction to clean the filter cartridge is issued.

[0063] This embodiment also provides a method for processing a cleaning instruction of a garden waste treatment system, comprising the following steps: Step 1, determine whether the control module obtains the above-mentioned cleaning instruction; if the cleaning instruction is obtained, execute step 2, otherwise continue to wait.
