[0002] In the field of environmental protection, with the acceleration of urbanization and the increase of industrial activities, the amount of solid waste generated has increased dramatically, and its effective treatment has become an urgent problem to be solved. Traditional solid waste treatment devices mostly use a single crushing or compression method to reduce the volume of waste for easy transportation and storage. However, with the improvement of environmental protection requirements and the increase in the demand for resource utilization, simple crushing or compression can no longer meet the requirements of modern waste treatment for high efficiency, cleanliness and resource utilization.

[0003] In response to this challenge, a series of improved solid waste treatment devices have emerged in the existing technology. These devices usually combine multiple processes such as crushing, screening, and classification to improve the treatment efficiency and waste separation effect. Among them, some devices use a design that combines a conveyor belt with a cutting component. The continuous movement of the conveyor belt sends the waste to the cutting area for bag breaking, which is convenient for subsequent crushing and other operations.

[0004] However, this type of processing device in the prior art has exposed some significant problems in practical application. First, the processing efficiency still needs to be improved, especially when processing large amounts of high-density waste, which is prone to blockage and affects continuous operation. Second, waste is prone to accumulate inside the equipment during the cutting process, increasing the difficulty of cleaning and maintenance.

[0035] Embodiment 1: Figures 1 to 13 As shown, the environmentally friendly solid waste treatment device of the present application includes a housing 100, a transmission component 200, a plurality of bag breaking components 300, a power assembly and a control unit.

[0036] The shell 100 is a hollow box as a whole, and a feeding port 110 for feeding is opened at the top of the shell 100.

[0037] The transmission component 200 is installed inside the housing 100 , and the transmission component 200 includes a driving wheel 210 , a driven wheel 220 , a conveyor belt 230 , a driving component 250 and a plurality of pushing plates 240 .

[0038] The driving wheel 210 and the driven wheel 220 are both rotatably connected in the housing 100, the conveyor belt 230 is sleeved on the driving wheel 210 and the driven wheel 220, and the feed port 110 is located above the conveyor belt 230 to facilitate transmission.

[0040] Specifically, in this embodiment, the end of the conveyor belt 230 close to the feed inlet 110 may be higher than the end away from the feed inlet 110 (the conveyor belt 230 is in an inclined state as a whole).

[0041] like Figure 2 As shown, the driving component 250 is installed on the outer wall of the housing 100, and the output shaft of the driving component 250 passes through the outer wall of the housing 100 and is connected to the driving wheel 210, and the driving component 250 drives the driving wheel 210 to rotate.

[0042] It should be noted that the driving component 250 in this embodiment may be a driving motor.

[0043] A plurality of push plates 240 are evenly fixed on the conveyor belt 230 .

[0044] It should be noted that the plurality of push plates 240 may be 10, 11, 12, 13, 14 push plates 240, etc., and the specific number is selected according to actual needs.

[0045] like Figure 2 , Figure 3 and Figure 4 As shown, the bag breaking component 300 is located in the middle of the conveyor belt 230 , and the bag breaking component 300 includes a mounting rod 310 , a sliding sleeve 320 and a blade 330 .

[0046] The mounting rod 310 is fixed in the housing 100 , and the mounting rod 310 is arranged parallel to the driving wheel 210 .

[0047] The sliding sleeve 320 is sleeved on the mounting rod 310 . The blade 330 is an annular cutter, and the blade 330 is sleeved on the sliding sleeve 320 .

[0048] The conveyor belt 230 includes a plurality of sub-belt bodies 231 , and a gap is left between two adjacent sub-belt bodies 231 . The gap is a knife groove, and the blade 330 passes through the corresponding knife groove and extends to the top of the conveyor belt 230 .

[0049] It should be noted that the mounting rod 310 is located below the upper conveyor belt 230 , and the number of blades 330 on one mounting rod 310 is at least one, and the number of blades 330 is the same as the number of blade grooves.

[0050] It should be noted that in this embodiment, the distance between the side wall of the blade 330 and the inner wall of the blade groove is 1 to 5 mm.

[0051] It should be noted that the height of the blade 330 above the corresponding position of the conveyor belt 230 is 1 to 3 centimeters.

[0052] The pushing plate 240 is provided with an opening corresponding to the blade 330 to prevent the blade 330 from colliding with the pushing plate 240 .

[0053] It should be noted that the knife groove in this embodiment is linear.

[0054] like Figure 5 As shown, both the driving wheel 210 and the driven wheel 220 are provided with a limiting ring block 221, and the sub-belt body 231 is provided with a corresponding slot, and the limiting ring block 221 is embedded in the corresponding slot, so that the sub-belt body 231 will not be offset.

[0055] Further, such as Figure 1 As shown, an oscillating component 120 is further provided on the inner wall of the housing 100 , and the oscillating component 120 is located below the discharge position of the conveyor belt 230 .

[0056] The oscillating component 120 includes a vibration plate 121 and a spring 122 , wherein the vibration plate 121 is hinged on the inner wall of the housing 100 , one end of the spring 122 is fixedly connected to the bottom surface of the vibration plate 121 , and the other end of the spring 122 is fixedly connected to the inner wall of the housing 100 .

[0057] It should be noted that a material pulling port may be opened at the bottom of the side wall of the shell 100 to carry away the solid waste scattered after the bag is broken.

[0058] It should be noted that the multiple bag breaking components 300 may be 2, 3, 4, 5, 6 bag breaking components 300, etc. The multiple bag breaking components 300 are arranged in parallel in sequence. The number of bag breaking components 300 is selected according to actual needs and will not be described in detail here.

[0059] The power assembly is used to provide energy for the operation of the processing device, preferably an AC power supply or a battery; the control unit is used to control the coordinated operation of various components of the processing device, preferably a programmable logic controller; both are prior arts and will not be described in detail here.

[0060] Preferably, the gap between the two sides of the conveyor belt 230 and the inner wall of the shell 100 is greater than the width of the knife groove, and a fan (not shown in the figure) is installed on the inner wall of the shell 100. The fan blows air toward the conveyor belt 230 and the lower position of the conveyor belt 230 to blow away the waste remaining on the conveyor belt 230 and the waste that falls into the conveyor belt 230 through the knife groove.

[0061] like Figure 1 As shown, when the processing device of the embodiment of the present application is actually running, the steps are as follows:

[0062] S1: Connect the power component (such as AC power or battery) and start the entire processing device through the control unit;

[0063] S2: Put the bag containing solid waste into the housing 100 from the feed port 110, and the bag falls on the inclined conveyor belt 230;

[0064] S3: The conveyor belt 230 starts to operate under the drive of the driving wheel 210, and the bag moves downward along with the conveyor belt 230;

[0065] S4: The bag slides over the blade 330, and the blade 330 cuts the bag. The blade 330 is not easy to hook the waste during the rotation process. At the same time, the push plate 240 pushes the bag and the waste stuck on the blade 330 to continue to slide down along the conveyor belt 230;

[0066] S5: After the cut bags and waste arrive at the discharge position of the conveyor belt 230, they fall onto the vibration plate 121. The vibration plate 121 vibrates under the action of the spring 122 to help further break up and separate the waste;

[0067] S6: The separated solid waste is transported away through the material pulling port at the bottom of the side wall of the shell 100 for subsequent processing.

[0068] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0069] 1. It solves the technical problems of low treatment efficiency, easy clogging and incomplete waste separation in the solid waste treatment device in the prior art; it realizes that the treatment device is not easy to be clogged when treating solid waste, and at the same time improves the treatment efficiency and waste separation effect;

[0070] 2. It realizes automatic cutting of the bag body and efficient treatment of waste, significantly improving the treatment efficiency;

[0071] 3. Reduced manual intervention and reduced the risk of secondary pollution during the treatment process;

[0072] 4. The number of blades 330, push plates 240 and bag breaking components 300 can be adjusted according to actual needs to meet the needs of waste treatment of different scales and types;

[0073] 5. The rotating setting of the blade 330 can prevent waste from accumulating near the blade 330, and the pushing plate 240 can also push away the waste remaining near the blade 330, so that the bag breaking effect of the bag breaking component 300 is more stable and efficient;

[0074] 6. The blade 330 rotates to cut the bag body, and the setting of the push plate 240 effectively avoids the problem of the bag body being retained during the cutting process;

[0075] 7. The provision of the oscillating component 120 helps to further break up and separate the garbage, thus improving the convenience of subsequent processing.

[0076] Embodiment 2: In the above embodiment, only a linear opening can be drawn on the bag body, and the opening is small, so that some waste in the bag body is difficult to be thrown out; the embodiment of the present application is optimized based on the above embodiment.

[0077] like Figure 6 and Figure 7 As shown, an annular movable magnetic sheet 340 is installed on both side walls of the blade 330, and a plurality of limiting magnetic sheets 232 are installed on the inner wall of the blade groove (the gap between two adjacent sub-belt bodies 231), and the limiting magnetic sheets 232 and the movable magnetic sheets 340 repel each other.

[0078] Further, such as Figure 6 and Figure 8 As shown, the sliding sleeve 320 is slidably mounted on the mounting rod 310, and the shape of the knife groove is a broken line.

[0079] It should be noted that in this embodiment, the interval between the side wall of the blade 330 and the inner wall of the knife groove is selected according to actual needs. When the blade 330 slides in the knife groove, driven by the movable magnetic plate 340 and the limiting magnetic plate 232, the width of the knife groove is large enough so that the blade 330 and the knife groove will not collide.

[0080] Preferably, the width of the knife groove may be 2 to 3 times the width of the blade 330 .

[0081] It should be noted that the shape of the knife groove depends on the shape of the sub-belt body 231. Therefore, when the present application defines the shape of the knife groove, it can be regarded as defining the shape of the sub-belt body 231 (especially the edge shape between adjacent sub-belt bodies 231) at the same time.

[0082] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0083] 1. By providing the movable magnetic sheet 340 and the limiting magnetic sheet 232, the blade 330 can be flexibly moved in the knife groove by magnetic repulsion, thereby avoiding direct collision between the blade 330 and the knife groove, reducing the noise and vibration caused by the collision, and improving the operation stability and service life of the device;

[0084] 2. The zigzag-shaped blade groove allows the blade 330 to generate a more complex motion trajectory during the cutting process, thereby forming a larger opening on the bag body, which helps to more thoroughly throw away the waste in the bag body;

[0085] 3. The adjustability of the knife groove width (through the interaction between the movable magnetic sheet 340 and the limiting magnetic sheet 232) enables the device to adapt to bags of different thicknesses and materials, thereby improving the versatility and adaptability of the device.

[0086] Embodiment 3: In the above embodiment, there is still room for improvement when breaking the bag body; the embodiment of the present application makes certain optimizations based on the above embodiment.

[0087] like Fig. 9 and Fig.10 As shown, in this embodiment, the number of blades 330 on each mounting rod 310 is at least 2; the shapes of two adjacent blade grooves are different, so that the movement trajectories of the two adjacent blades 330 are different, sometimes approaching each other and sometimes moving away from each other, thereby pulling the bag body.

[0088] It should be noted that, in the present embodiment, the number of blades 330 on each mounting rod 310 may be 2, 3, 4, 5, or 6, and the specific number is selected according to actual needs.

[0089] It should be noted that the bending degree of the knife groove track can be adjusted with reference to the volume of the bag containing the waste, so that the bag can be cut by multiple blades 330 in multiple tracks.

[0090] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0091] 1. The dual effects of cutting and pulling make the bag breaking process more efficient and thorough, reducing the waste residue caused by incomplete cutting;

[0092] 2. Increasing the number of blades 330 and changing the shape of the blade groove significantly improves the processing efficiency, allowing the device to open multiple openings in the bag body in a shorter time, and these openings will form larger openings after being pulled by the blades 330, and even two adjacent openings will be combined into a larger opening under the tearing of the blades 330, further improving the processing efficiency.

[0093] Embodiment 4: In the above embodiment, the blade 330 can only slide along the mounting rod 310. If the angle at the corner of the knife groove is large, it will affect the movement of the blade 330. This requires a larger width of the knife groove to meet the movement of the blade 330. The embodiment of the present application is optimized based on the above embodiment.

[0094] like Fig.11 , Fig.12 and Fig.13 As shown, the sliding sleeve 320 is a sphere as a whole, and the mounting rod 310 slides through the sliding sleeve 320; the blade 330 is rotatably connected to the sliding sleeve 320 via two rotating shafts 331.

[0095] It should be noted that the two rotating shafts 331 are relatively arranged at the top and bottom of the sliding sleeve 320, and the rotating shafts 331 are vertically arranged.

[0096] The knife groove in this embodiment can be a broken line or a smooth curve. The blade 330 can change with the angle of the knife groove and tear the bag containing waste. In this embodiment, the width of the knife groove can be 1.5 to 2 times the width of the blade 330.

[0097] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0098] 1. The spherical-shaped sliding sleeve 320 allows the blade 330 to move more flexibly in three-dimensional space, and is no longer limited to a two-dimensional plane, so that the blade 330 can better adapt to knife grooves of different shapes and angles. The blade 330 can penetrate the bag more deeply and generate greater destructive force during the tearing process, which helps to more thoroughly throw away the waste in the bag;

[0099] 2. Regardless of whether the blade groove is in the shape of a broken line or a smooth curve, the blade 330 can adapt to its angle change through the flexible rotation of the rotating shaft 331 on the sliding sleeve 320, which can ensure the stability and reliability of the blade 330 during movement and avoid collision and damage.

[0100] In summary, the environmentally friendly solid waste treatment device proposed in this application solves the technical problems of low treatment efficiency, easy clogging, and incomplete waste separation in the solid waste treatment device in the prior art; it realizes that the treatment device is not easy to be clogged when treating solid waste, and at the same time improves the treatment efficiency and waste separation effect.

[0101] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
