Description

Technical Field

[0001] This invention relates to the field of construction waste treatment technology, and in particular to a waste crushing and recycling device and crushing method. Background Technology

[0002] Properly disposing of construction waste is an important aspect of urban management in municipal engineering. It is related to the aesthetics and sanitation of the urban environment, as well as the rational use of resources and environmental protection.

[0003] Currently, construction waste is generally processed by crushing it with a crushing device before recycling. However, existing crushing devices can only coarsely crush all types of waste, failing to achieve targeted crushing for different types of waste, resulting in poor crushing efficiency. Furthermore, the waste crushed by existing crushing devices retains a large amount of moisture, which wastes water resources and makes the crushed waste difficult to process. Summary of the Invention

[0004] The purpose of this invention is to provide a waste crushing and recycling device and a crushing method to solve the technical problems of poor crushing effect and inability to remove moisture from waste in the prior art.

[0005] Based on the above concept, the technical solution adopted by this invention is as follows:

[0006] A waste shredding and recycling device, comprising:

[0007] A crushing chamber is provided with an inlet and an outlet. A crushing space is formed inside the crushing chamber, which is divided into an upper crushing space and a lower crushing space from top to bottom. The upper crushing space and the lower crushing space are interconnected. The upper crushing space is connected to the inlet, and the lower crushing space is connected to the outlet.

[0008] The first crushing component includes a crushing drum. At least two crushing drums are arranged in the upper crushing space. The crushing drums are rotatable around their own axis. A crushing gap is formed between two adjacent crushing drums. Waste can be crushed in the crushing gap and put into the lower crushing space.

[0009] The second crushing component is disposed in the lower crushing space. The second crushing component includes a rotating shaft and crushing blades. A plurality of crushing blades are disposed circumferentially around the rotating shaft. The rotating shaft can rotate along its own axis to drive the crushing blades to cut the waste.

[0010] The water removal tank has a water removal space inside, which is connected to the discharge port. The water removal tank can remove moisture from the waste.

[0011] The first crushing component further includes a first motor, a driving gear, and a driven gear. There are two crushing drums. The driving gear and the driven gear are each connected to one of the crushing drums. The driving gear and the driven gear mesh with each other. The first motor can drive the driving gear to rotate.

[0012] The rotating shaft is provided in two parallel configurations, and the crushing blades on the two rotating shafts are arranged in an alternating pattern.

[0013] It also includes a spraying assembly, which includes a water pump and a nozzle. The nozzle is connected to the pulverizing chamber, and the water pump can supply water to the nozzle. The nozzle is used to clean the pulverizing space.

[0014] The pulverizing chamber has an installation port on at least one side, which communicates with the pulverizing space. An installation plate is detachably connected to the installation port. A nozzle is provided on the front side of the installation plate, and a sealing block is provided on the back side of the installation plate. The front and back sides can selectively face the pulverizing space.

[0015] The device has two mounting ports, which are respectively located on two opposite side walls of the crushing chamber.

[0016] The discharge port and the dewatering tank are connected by a guide channel, which is inclined at a first angle. The upper end of the guide channel is connected to the discharge port, and the lower end of the guide channel is connected to the dewatering space.

[0017] The bottom of the guide groove is equipped with a vibrating element.

[0018] The dewatering tank is equipped with a telescopic rod and a squeezing plate. The telescopic rod is located on the inner wall of the dewatering space, and the squeezing plate is located on the telescopic end of the telescopic rod. The telescopic rod can extend and retract along its own axis, so that the squeezing plate squeezes the waste, thereby removing the water from the waste.

[0019] A waste shredding method, employing the aforementioned waste shredding and recycling device, includes:

[0020] Step 1: First, drive the crushing drum and the rotating shaft to rotate;

[0021] Step 2: Put the waste to be crushed into the feed inlet;

[0022] Step 3: After being crushed, the waste is discharged from the outlet and enters the dewatering tank;

[0023] Step 4: Remove water from the waste through the dewatering tank. After the water is removed from the waste, open the dewatering tank and take out the waste.

[0024] The beneficial effects of this invention are:

[0025] The waste shredding and recycling device proposed in this invention features two sets of shredding components within the shredding chamber. A shredding roller in the upper shredding space initially crushes the waste, while shredding blades in the lower shredding space further refine and cut it. The shredding roller's crushing action facilitates the shredding of hard waste such as plastics and wood panels, while the shredding blades' cutting action facilitates the shredding of soft waste such as fabrics and paper. Through the coordinated operation of the shredding roller and blades, more precise shredding can be achieved according to the characteristics of different types of waste, resulting in high shredding efficiency. Furthermore, the dewatering tank effectively removes moisture from the shredded waste, ensuring that the processed waste is drier and easier for subsequent processing or resource recycling. This not only saves water resources but also reduces the processing difficulty and cost caused by high water content in the waste. Attached Figure Description

[0046] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0047] This invention provides a waste shredding and recycling device that can perform targeted shredding of various types of waste with good shredding effect.

[0048] See Figures 1 to 3 The waste crushing and recycling device provided in this embodiment of the invention includes a crushing box 10, a first crushing component 20, a second crushing component 30, and a water removal tank 70. The crushing box 10 has an inlet 11 and an outlet 12. A crushing space is formed inside the crushing box 10, which is divided into an upper crushing space and a lower crushing space from top to bottom. The upper and lower crushing spaces are interconnected; the upper crushing space is connected to the inlet 11, and the lower crushing space is connected to the outlet 12. The first crushing component 20 includes crushing rollers 21. At least two crushing rollers 21 are arranged in the upper crushing space. The crushing rollers 21 can rotate around their own axis, and a crushing gap is formed between adjacent crushing rollers 21, allowing the waste to be crushed in the crushing gap and fed into the lower crushing space. The second crushing component 30 is located in the lower crushing space. The second crushing component 30 includes a rotating shaft 31 and crushing blades 32. Multiple crushing blades 32 are arranged circumferentially around the rotating shaft 31. The rotating shaft 31 can rotate axially, driving the crushing blades 32 to cut the waste. A dewatering tank 70 has a dewatering space connected to the outlet 12, and the dewatering tank 70 can remove moisture from the waste.

[0049] By incorporating two sets of crushing components within the crushing chamber 10, the crushing roller 21 in the upper crushing space initially crushes the waste, while the crushing blades 32 in the lower crushing space further refine and cut the waste. The crushing roller 21 facilitates the crushing of hard waste such as plastics and wood panels, while the crushing blades 32 facilitate the crushing of soft waste such as fabrics and paper. Through the coordinated operation of the crushing roller 21 and the crushing blades 32, more precise crushing can be achieved according to the characteristics of different types of waste, resulting in high crushing efficiency. Furthermore, the water tank 70 effectively removes moisture from the crushed waste, ensuring that the treated waste is drier and easier for subsequent processing or resource recycling. This not only saves water resources but also reduces the processing difficulty and cost caused by high water content in the waste.

[0050] In this embodiment, the crushing box 10 is rectangular and placed horizontally on the ground. The crushing roller 21 and the rotating shaft 31 are arranged in parallel and both extend along the length of the crushing box 10. For the convenience of describing in conjunction with the accompanying drawings, the directions in the following description are based on the directions shown in the accompanying drawings, but are not limited thereto.

[0051] See Figure 3 and Figure 4 Regarding the first crushing component 20, it further includes a first motor 22, a driving gear 23, and a driven gear 24. Two crushing drums 21 are provided, with the driving gear 23 and driven gear 24 each connected to one crushing drum 21. The driving gear 23 and driven gear 24 mesh with each other, and the first motor 22 drives the driving gear 23 to rotate. Through the cooperation of the first motor 22, driving gear 23, and driven gear 24, precise speed and direction control can be achieved, ensuring that the crushing drum 21 operates at an appropriate speed and force. The meshing of the driving gear 23 and driven gear 24 provides high stability. The first motor 22 directly drives the driving gear 23, transmitting power to the driven gear 24 and its connected crushing drum 21 through gear meshing, thereby driving the crushing drum 21 to rotate and achieve the crushing effect. This has higher transmission efficiency, reduces energy loss, and achieves a more environmentally friendly and economical waste treatment process.

[0052] In other embodiments, four, six, or other crushing components may be provided depending on the size of the crushing box 10 and the amount of waste to be crushed. It is worth noting that, in order to improve crushing efficiency, it is best to arrange multiple crushing rollers 21 in pairs, with the two crushing rollers 21 rotating in opposite directions, so as to facilitate crushing the waste from the crushing gap and moving it from top to bottom into the lower crushing space, resulting in higher crushing efficiency.

[0053] Furthermore, in this embodiment, the width of the pulverizing gap between the two pulverizing rollers 21 is greater than 20cm and less than 100cm. This avoids the pulverizing gap being too narrow, causing the waste to get stuck and unable to move downwards, or too wide, preventing the waste from being pulverized. In other embodiments, the width of the pulverizing gap can also be adjusted according to specific circumstances, and is not limited here.

[0054] Preferably, the outer surface of the crushing drum 21 can be provided with multiple blocking protrusions. The blocking protrusions can increase the friction force and prevent the garbage from slipping out of the crushing gap before it is crushed. At the same time, the blocking protrusions can also hit the garbage during the rotation of the crushing drum 21, so as to further crush the garbage.

[0055] Regarding the second crushing component 30, specifically, two rotating shafts 31 are provided, arranged in parallel, with the crushing blades 32 on the two rotating shafts 31 arranged in a staggered pattern. The staggered arrangement of the crushing blades 32 on the two parallel rotating shafts 31 allows for the processing of more waste in a shorter time, ensuring that each crushing blade 32 effectively cuts the waste during rotation, reducing blank areas in waste processing, and thus significantly improving crushing efficiency. Furthermore, the staggered arrangement of the crushing blades 32 ensures the uniformity of waste crushing during the crushing process. Compared to a single rotating shaft 31 design, the dual-shaft staggered configuration can process waste more effectively, ensuring that the waste is uniformly crushed and avoiding problems of localized over-crushing or insufficient crushing.

[0056] Furthermore, the second crushing assembly 30 also includes a second motor 33, which drives the rotating shaft 31 to rotate along its own axial direction, thereby driving the crushing blades 32 to rotate at high speed to improve the crushing efficiency of the waste.

[0057] Preferably, the rotation speed of the rotating shaft 31 of the second crushing component 30 is adjustable to adapt to the crushing requirements of waste with different hardness.

[0058] See Figure 5 and Figure 6After the waste is crushed, a large amount of waste residue remains in the crushing space of the crushing box 10. If not cleaned in time, it will clog the equipment and affect the next crushing process; on the other hand, long-term accumulation of waste will corrode the crushing box 10, thereby reducing its service life. Therefore, the waste crushing and recycling device provided in this embodiment also includes a spraying component 40, which includes a water supply pump 41 and a nozzle 42. The nozzle 42 is connected to the crushing box 10, and the water supply pump 41 can supply water to the nozzle 42, which is used to clean the crushing space. By spraying water to clean the crushing space after crushing, dust and residue generated during the crushing process can be effectively removed, keeping the inside of the equipment clean. This helps maintain a good working environment and reduces equipment failures caused by dust or residue. In addition, in some cases, water can be sprayed into the crushing space during the crushing process to reduce dust caused by waste and ensure air quality.

[0059] Preferably, the nozzle 42 is equipped with an adjustable nozzle so that the water pressure and spray pattern can be adjusted according to the type of waste and the need for pulverization, so as to achieve more effective cleaning and pre-wetting.

[0060] Regarding the specific installation location of the nozzle 42, in other embodiments, the nozzle 42 can be fixedly connected to the inner wall of the pulverizing chamber 10, and the water pump 41 is located outside the pulverizing chamber 10 and communicates with the nozzle 42. When cleaning is required, the water pump 41 supplies water to the nozzle 42 to achieve a cleaning effect. However, during the pulverization process, the pulverized waste residue is easily scattered onto the nozzle 42, clogging the nozzle and causing the nozzle 42 to malfunction, thus affecting the cleaning effect. Therefore, in this embodiment, at least one side of the pulverizing chamber 10 is provided with an installation port 13, which communicates with the pulverizing space. An installation plate 43 is detachably connected to the installation port 13. The nozzle 42 is provided on the front side of the installation plate 43, and a sealing block 44 is provided on the back side of the installation plate 43. The front and back sides can be selectively facing the pulverizing space, thus providing high flexibility and adaptability. Depending on the characteristics of the cleaning or pulverizing needs, the operator can choose to face the nozzle 42 towards the pulverizing space for cleaning, or face the sealing block 44 towards the pulverizing space to prevent waste from damaging the nozzle 42. The removable mounting plate 43 design makes the maintenance and replacement of the nozzles 42 much easier. When the nozzles 42 become clogged or need to be replaced, operators can easily remove the mounting plate 43 for cleaning or replacement without the need for cumbersome disassembly of the entire pulverizing chamber 10, greatly reducing maintenance costs and time. Furthermore, by providing the removable mounting plate 43, the device's functionality extends beyond water cleaning. By replacing components on the mounting plate 43, the device's capabilities can be expanded, such as adding different types of nozzles 42 for disinfection or adding specific chemical agents, enhancing the versatility of the spray assembly 40 and meeting a wider range of application needs. Further details will not be elaborated upon here.

[0061] Furthermore, a fixed housing 47 is provided on the front side of the mounting plate 43, and a water storage cavity 471 is formed inside the fixed housing 47. Multiple nozzles 42 are arranged at intervals on the outer surface of the fixed housing 47, and each nozzle 42 is connected to the fixed housing 47. In addition, the spraying assembly 40 also includes a connecting pipe 45. One end of the connecting pipe 45 passes through the mounting plate 43 and is connected to the water storage cavity 471; the other end of the connecting pipe 45 is located on the sealing block 44. A water inlet pipe 411 is installed at the input end of the water supply pump 41, and a water outlet pipe 412 is installed at the output end of the water supply pump 41. Conduits 413 are symmetrically installed at both ends of the water outlet pipe 412. A threaded connecting pipe 414 is installed at one end of the conduit 413, and the threaded connecting pipe 414 can be threadedly connected to the connecting pipe 45. When the pulverizing space needs to be cleaned, first, the front of the mounting plate 43 faces the pulverizing space, with the sealing block 44 on the outside. Then, the connecting pipe 45 is threadedly connected to the threaded connecting pipe 414 at one end of the sealing block 44. Water is supplied to the inlet pipe 411, and the water flows through the outlet pipe 412, then through the conduit 413 into the water storage chamber 471, and finally sprayed out through the nozzle 42, thus completing the cleaning process of the pulverizing space. When pulverizing operations are required in the pulverizing space, the threaded connecting pipe 414 and the connecting pipe 45 are screwed apart, and the mounting plate 43 is removed, flipped over, and then the mounting plate 43 is installed into the mounting port 13, so that the back of the mounting plate 43 faces the pulverizing space. The sealing block 44 then seals the pulverizing space. In addition, to prevent debris from splashing into the connecting pipe 45, a sealing cap 46 can be detachably installed on the end of the connecting pipe 45.

[0062] Furthermore, to improve the cleaning effect of the crushing space, two mounting ports 13 are provided, one on each of the two opposite side walls of the crushing chamber 10. By providing two mounting ports 13 on opposite side walls, all-around cleaning of the crushing space can be achieved. This allows the nozzles 42 to spray water from different angles, effectively improving cleaning efficiency and coverage, ensuring no blind spots, and thus more thoroughly removing residues and dust generated during the crushing process. In addition, greater operational flexibility is provided. Depending on the specific type of crushed waste and cleaning needs, one can choose to use one side of the nozzles 42 for localized cleaning, or simultaneously use both sides of the nozzles 42 for comprehensive cleaning, meeting different operational requirements.

[0063] See Figure 1 and Figure 7After the waste is shredded, it needs to be transported to the dewatering tank 70 for dewatering. To improve the efficiency of waste transportation, in this embodiment, the discharge port 12 and the dewatering tank 70 are connected by a guide channel 50. The guide channel 50 is inclined at a first angle, with its upper end connected to the discharge port 12 and its lower end connected to the dewatering space. The guide channel 50 provides a guiding effect for waste transportation, guiding all waste to slide into the dewatering tank 70, avoiding waste splashing everywhere and affecting the cleaning effect. The guide channel 50 ensures that the shredded waste can smoothly slide from the discharge port 12 to the dewatering tank 70, reducing possible blockages and delays during the process, especially for wet or sticky waste materials. The inclined design of the guide channel 50 allows the shredded waste to automatically flow into the dewatering tank 70 by gravity, preventing waste from sticking to the guide channel 50 and causing blockages. Furthermore, as the waste moves downwards under gravity, some moisture naturally separates and flows away, reducing the need for additional power and improving the efficiency of transportation and initial dewatering. In this embodiment, the first angle is greater than or equal to 30 degrees and less than or equal to 60 degrees, within which the guiding effect of the guide groove 50 is optimal. However, the first angle is not limited, and in other embodiments, different angles can be set according to actual conditions.

[0064] To further improve the transport efficiency of the guide trough 50, a vibrating element 51 is provided at the bottom of the guide trough 50. When waste flows through the guide trough 50, the vibrating element 51 can be controlled to vibrate, thereby causing the guide trough 50 to vibrate and shake off the waste attached to or adhering to the inner wall of the guide trough 50, allowing it to flow into the dewatering tank 70. This effectively reduces blockage and material accumulation during the transport process, maintaining the continuity and smoothness of material flow, especially for wet or sticky materials. In this embodiment, the vibrating element 51 is a vibrating motor. In other embodiments, a vibrating hydraulic cylinder, etc., can also be used; no limitation is made here.

[0065] Preferably, in order to facilitate the installation of the guide groove 50 and to facilitate the connection between the discharge port 12 and the dewatering tank 70 through the guide groove 50, a support component 60 is also provided in this embodiment. The support component 60 includes a support plate 61 and a support frame 62. The support frame 62 is fixedly connected to the support plate 61. The dewatering tank 70 is disposed on the support plate 61, and the crushing box 10 is disposed on the support frame 62, thereby creating a height difference between the crushing box 10 and the dewatering tank 70, which facilitates the inclined installation of the guide groove 50.

[0066] See Figure 8 and Figure 9After the waste flows into the dewatering tank 70 through the guide trough 50, it needs to be dewatered through the dewatering tank 70. Regarding the specific structure of the dewatering tank 70, in this embodiment, a telescopic rod 71 and a squeezing plate 72 are provided inside the dewatering tank 70. The telescopic rod 71 is located on the inner wall of the dewatering space, and the squeezing plate 72 is located on the telescopic end of the telescopic rod 71. The telescopic rod 71 can extend and retract along its own axial direction, allowing the squeezing plate 72 to squeeze the waste, thereby removing the moisture from the waste. Through physical squeezing, the squeezing plate 72 can effectively squeeze out the moisture from the waste. The telescopic rod 71's extension and retraction allows the squeezing plate 72 to adapt to different volumes of waste processing needs. Whether it's dewatering small batches or large quantities of waste, effective processing can be achieved by adjusting the extension and retraction of the telescopic rod 71, enhancing the adaptability of the dewatering tank 70. Furthermore, the design of the telescopic rod 71 and the squeezing plate 72 fully utilizes the internal space of the dewatering tank 70, optimizing the dewatering process through mechanization without requiring additional floor space, making the device more compact and efficient.

[0067] Furthermore, to facilitate the drainage of water after the garbage is squeezed, in this embodiment, the drive motor 73 is installed on the outer wall of the water removal tank 70, and the telescopic rod 71 is installed on the top wall of the water removal space. The drive motor 73 can drive the telescopic rod 71 to extend and retract. The telescopic rod 71 can extend and retract in the vertical direction to drive the squeezing plate 72 to move. A support plate 74 is provided at the bottom of the water removal tank 70. A plurality of drainage holes 741 are provided on the support plate 74. The drainage holes 741 penetrate the support plate 74 along the thickness direction of the support plate 74. A drainage cavity 76 is formed between the support plate 74 and the bottom wall of the water removal space. The drainage holes 741 are connected to the drainage cavity 76. A drainage pipe 75 is provided on the outer wall of the water removal tank 70. The drainage pipe 75 is connected to the drainage cavity 76. In use, the garbage flowing from the guide trough 50 moves to the support plate 74 of the dewatering tank 70. The telescopic rod 71 is extended by remote control, which drives the squeezing plate 72 to move down and squeeze the garbage. The garbage is deformed after being compressed, and the water is squeezed out. The water flows from the drain hole 741 of the support plate 74 to the drain chamber 76 below, and then is discharged from the drain pipe 75.

[0068] In addition, the dewatering tank 70 is also equipped with a door 77, which is hinged to the side of the dewatering tank 70. The door 77 can open or close the dewatering tank 70, so that the garbage can be taken out of the dewatering tank 70 after the garbage has been dewatered.

[0069] Preferably, the water tank 70 is equipped with an ultraviolet disinfection lamp, which is used to disinfect the waste during the treatment process, kill bacteria and viruses in the waste, and improve the hygiene and safety level of waste treatment.

[0070] This invention also provides a waste shredding method, which uses the above-mentioned waste shredding and recycling device. The specific operation steps are as follows:

[0071] Step 1: First, drive the crushing drum 21 and the rotating shaft 31 to rotate;

[0072] In this step, the first motor 22 is driven by remote control to drive the drive gear 23 to rotate, and the power is transmitted to the driven gear 24 and the crushing drum 21 connected to it through gear meshing, thereby driving the crushing drum 21 to rotate; at the same time, the second motor 33 is driven by remote control to drive the rotating shaft 31 to rotate along its own axis, thereby driving the crushing blade 32 to rotate at high speed.

[0073] It is worth noting that before step 1, the threaded connecting pipe 414 and the connecting pipe 45 need to be screwed apart, and the mounting plate 43 needs to be removed, flipped over, and then the mounting plate 43 is installed into the mounting port 13 so that the back of the mounting plate 43 faces the crushing space. The sealing cap 46 is installed at the end of the connecting pipe 45, and the sealing block 44 seals the crushing space.

[0074] Step 2: Put the waste to be crushed into the feed inlet 11.

[0075] In this step, the operator evenly and gradually feeds the waste into the crushing box 10 from the feed inlet 11. After entering through the feed inlet 11, the waste is first crushed by the crushing roller 21 located in the upper crushing space. After crushing, it flows into the lower crushing space through the crushing gap, and is then cut and crushed by the crushing blades 32 in the lower crushing space before flowing out from the discharge outlet 12.

[0076] Step 3: After being crushed, the waste is discharged from the discharge port 12 and then enters the dewatering tank 70;

[0077] In this step, after the waste is crushed, it is discharged from the discharge port 12 and slides through the guide trough 50 into the dewatering space of the dewatering tank 70. At the same time, the operator remotely controls the vibrator 51 to vibrate, preventing the waste from adhering to the guide trough 50.

[0078] Step 4: Remove water from the garbage through the water removal tank 70. After the water in the garbage is removed, open the water removal tank 70 and take out the garbage.

[0079] In this step, the waste flowing from the guide trough 50 moves to the support plate 74 of the dewatering tank 70. The telescopic rod 71 extends via remote control, causing the squeezing plate 72 to move downwards and squeeze the waste. The waste deforms under pressure, squeezing out moisture. The moisture flows from the drain hole 741 of the support plate 74 to the drain chamber 76 below, and then exits through the drain pipe 75. After the moisture in the waste is removed, the cabinet door is opened, the waste is removed, and the waste is recycled.

[0080] Understandably, when there is too much moisture in the garbage, the telescopic rod 71 can be repeatedly extended and retracted to squeeze the garbage multiple times, thereby achieving a better water removal effect.
