Description

Technical Field

[0001] The present invention relates to the technical field of solid waste treatment, and in particular to a solid waste treatment device for environmental protection machinery. Background Art

[0002] The mechanical structure used in the existing technology for processing solid waste is simple, the material is fed evenly, and the probability of failure can be reduced. However, due to the differences in the size of the solid waste, if they are crushed together, the crushing efficiency will be low.

[0003] In response to the above problems, a Chinese patent with publication number "CN112452404B" discloses a solid waste crushing device, which belongs to the field of solid waste treatment technology, and includes a crushing component, a shaking-off component and a crushing component. The crushing component, the shaking-off component and the crushing component are arranged in sequence from top to bottom, and the crushing component is used to perform the first crushing operation on the solid waste. The above scheme can mainly crush the solid waste once and then crush it twice. After the solid waste is crushed once, there will no longer be the problem of size differences, which is conducive to the subsequent crushing process. However, the above scheme still has certain problems. First, only a single crushing column is used during crushing, and solid waste with higher hardness cannot be crushed and decomposed. Secondly, the solid waste is prone to uneven force during crushing, resulting in poor crushing effect. In addition, the solid waste will emit a large amount of dust when crushed, and the above scheme does not process this large amount of dust, which is not environmentally friendly.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Example 1

[0033] Reference Figure 1-2 A solid waste treatment device for environmental protection machinery includes a bottom plate 1, an intermediate plate 2, a top plate 3, and a crushing assembly. The crushing assembly consists of a crushing sleeve 5, a crushing disc 16 and a plurality of blades 17, which are used to crush solid waste. The crushing sleeve 5 is rotatably connected to the upper end of the bottom plate 1, and the crushing disc 16 is located directly above the crushing sleeve 5. A plurality of blades 17 are all arranged at the lower end of the crushing disc 16. A driving mechanism for driving the crushing action of the crushing disc 16 is installed between the intermediate plate 2 and the top plate 3, and a driving motor 8 is fixedly installed on the upper end of the top plate 1.

[0034] The bottom plate 1, the middle plate 2 and the top plate 3 are fixedly connected by a connecting frame 7. Four supporting legs 4 are provided at the lower end of the bottom plate 1. The lower end of the bottom plate 1 is also provided with a solenoid valve cover 6 that cooperates with the crushing sleeve 5.

[0035] The driving mechanism includes a reciprocating screw 18 and a screw nut 19. The reciprocating screw 18 is rotatably connected between the middle plate 2 and the top plate 3 and is coaxially fixedly connected to the output shaft of the drive motor 8. The screw nut 19 is threadedly connected to the reciprocating screw 18, and the rolling plate 16 is fixedly connected to the screw nut 19 through a connecting rod 20. The connecting rod 20 passes through the middle plate 2 and is slidably connected to the middle plate 2.

[0036] In this embodiment, when the solid waste treatment device for environmental protection machinery is started, the driving motor 8 fixedly mounted on the upper end of the top plate 1 starts to operate.

[0037] When the drive motor 8 is running, its output shaft drives the reciprocating screw 18, which is coaxially fixedly connected to it, to rotate. Since the reciprocating screw 18 is rotatably connected between the intermediate plate 2 and the top plate 3, and the screw nut 19 is threadedly connected to the reciprocating screw 18, according to the principle of thread transmission, as the reciprocating screw 18 rotates, the screw nut 19 will reciprocate linearly on the reciprocating screw 18.

[0038] The screw nut 19 is fixedly connected to the rolling disc 16 through the connecting rod 20, and the connecting rod 20 passes through the middle plate 2 and is slidingly connected to the middle plate 2, so the reciprocating linear motion of the screw nut 19 can drive the connecting rod 20 and the rolling disc 16 connected thereto to perform reciprocating linear motion along the vertical direction.

[0039] As the crushing disc 16 reciprocates, several blades 17 at the lower end of the crushing disc 16 move up and down. As the crushing disc 16 moves downward, the blades 17 gradually approach the solid waste within the crushing sleeve 5, which is connected to the upper end of the base plate 1, crushing and crushing the solid waste. As the crushing disc 16 moves upward, the blades 17 move away from the solid waste, preparing for the next round of crushing.

[0040] Example 2

[0041] Reference Figure 1 and Figure 4-5 , which is different from the first embodiment in that it also includes a spray assembly, which consists of a through pipe 29 and several atomizing nozzles 30, which are used to spray atomized water for environmental protection and dust reduction. The through pipe 29 is fixedly connected to the side of the middle plate 2, and the several atomizing nozzles 30 are all inclined below the through pipe 29 and the spray range covers the opening area of the crushing sleeve 5. A water delivery mechanism for delivering water to the spray assembly is installed at the upper end of the top plate 1. The water delivery mechanism includes a water delivery cylinder 14, a piston 32, a water inlet pipe 15 and a water outlet pipe 28. The water delivery cylinder 14 is fixedly connected to the upper end of the top plate 3, and the piston 32 is sealingly and slidably connected between the inner wall of the water delivery cylinder 14. The water inlet pipe 15 is connected between the water delivery cylinder 14 and the external water source, and the water outlet pipe 28 is connected between the water delivery cylinder 14 and the through pipe 29.

[0042] The water delivery mechanism is connected to the drive motor 8 through a pushing mechanism, which includes a half gear 25, a rack 26, a push rod 27 and a return spring 31. The half gear 25 is coaxially fixedly connected to the output shaft of the drive motor 8, the rack 26 is slidably connected to the top plate 3 and meshes with the half gear 25, the push rod 27 is fixedly connected between the piston 32 and the rack 26, and the return spring 31 is elastically connected between the piston 32 and the inner wall of the water delivery cylinder 14.

[0043] A one-way valve is installed in the water inlet pipe 15 to only allow water to flow from the external water source to the water delivery cylinder 14 , and a one-way valve is installed in the water outlet pipe 28 to only allow water to flow from the water delivery cylinder 14 to the through-channel 29 .

[0044] In this embodiment, when the driving motor 8 is started, in addition to driving the reciprocating screw 18 to operate the crushing assembly, it also drives the half gear 25 coaxially fixedly connected thereto to rotate.

[0045] During the rotation of the half gear 25, it will engage with the rack 26 that is slidably connected to the top plate 3 for transmission. Since only half of the half gear 25 has teeth, it will intermittently engage with the rack 26 when the half gear 25 rotates. When the half gear 25 engages with the rack 26, it will push the rack 26 to slide on the top plate 3.

[0046] Because the push rod 27 is fixedly connected between the piston 32 and the rack 26, the sliding of the rack 26 drives the piston 32 to slide within the water delivery cylinder 14 via the push rod 27. When the piston 32 slides away from the water inlet pipe 15, the space within the water delivery cylinder 14 increases and the pressure decreases. Under the action of the pressure difference, water from the external water source flows into the water delivery cylinder 14 through the water inlet pipe 15. At this time, the one-way valve in the water inlet pipe 15 opens, and the one-way valve in the water outlet pipe 28 closes, preventing water from flowing out of the water outlet pipe 28.

[0047] When the half gear 25 continues to rotate and disengages from the rack 26, the piston 32 will slide toward the water inlet pipe 15 under the elastic action of the return spring 31. At this time, the space in the water delivery cylinder 14 decreases, the pressure increases, and water will flow into the through pipe 29 through the water outlet pipe 28. At this time, the one-way valve in the water outlet pipe 28 opens, and the one-way valve in the water inlet pipe 15 closes, preventing water from flowing back to the external water source.

[0048] The water entering the through-pipe 29 is sprayed out through a plurality of atomizing nozzles 30 obliquely arranged below it. Since the spraying range of the atomizing nozzles 30 covers the opening area of the crushing sleeve 5, the sprayed atomized water can reduce the dust generated when the solid waste is crushed in the crushing sleeve 5, thereby playing an environmental protection role.

[0049] Example 3

[0050] Reference Figure 1 、 Figure 3 and Figure 6 The difference from Examples 1 and 2 is that it also includes a rotating assembly, which consists of a first gear ring 9 and a second gear ring 10, and is used to drive the crushing sleeve 5 to rotate intermittently. The first gear ring 9 and the second gear ring 10 are both rotatably connected to the upper end of the base plate 1 and mesh with each other, and the first gear ring 9 is sleeved on the outside of the crushing sleeve 5.

[0051] The rotating assembly is connected to the driving mechanism through a transmission mechanism. The transmission mechanism includes an internal threaded sleeve 11, a threaded rod 12 and a bent rod 13. The internal threaded sleeve 11 is rotatably connected to the upper end of the base plate 1 and is located at the inner ring of the second gear ring 10. The threaded rod 12 is threadedly connected in the internal threaded sleeve 11. One end of the bent rod 13 is fixedly connected to the screw nut 19, and the other end is fixedly connected to the upper end of the threaded rod 12. A one-way mechanism for controlling the one-way rotation of the second gear ring 10 is installed between the second gear ring 10 and the internal threaded sleeve 11.

[0052] The one-way mechanism includes a ratchet 22, a secondary wheel 21, a pawl 23 and a shift rod 24. The ratchet 22 is sleeved on the outer side of the lower end of the internally threaded sleeve 11. The secondary wheel 21 is fixedly connected to the inner ring side wall of the second gear ring 10. The three sets of pawls 23 and the shift rod 24 are all arranged on the inner side of the secondary wheel 21 and are rotatably connected to it. The pawl 23 and the shift rod 24 cooperate with the ratchet 22.

[0053] In this embodiment, based on the first and second embodiments, when the drive motor 8 is started, the drive motor 8 drives the reciprocating screw 18 to rotate, so that the screw nut 19 performs reciprocating linear motion on the reciprocating screw 18 .

[0054] Since one end of the bent rod 13 is fixedly connected to the screw nut 19 and the other end is fixedly connected to the upper end of the threaded rod 12 , the reciprocating linear motion of the screw nut 19 is transmitted to the threaded rod 12 through the bent rod 13 .

[0055] The threaded rod 12 is threadedly connected to the internal threaded sleeve 11. When the threaded rod 12 makes a reciprocating linear motion up and down along with the bent rod 13, the internal threaded sleeve 11 will be driven to rotate due to the action of the thread (because the internal threaded sleeve 11 is rotatably connected to the upper end of the base plate 1 and can only rotate).

[0056] As the internally threaded sleeve 11 rotates, the ratchet 22, which is mounted on the outside of the lower end of the internally threaded sleeve 11, also rotates. During this rotation, the ratchet 22 engages with a pawl 23 and a lever 24 (both mounted on the inside of and rotatably connected to the secondary gear 21 fixedly attached to the inner sidewall of the second ring gear 10).

[0057] When the ratchet wheel 22 rotates in a specific direction, the pawl 23 engages with the teeth of the ratchet wheel 22, thereby driving the auxiliary wheel 21 to rotate. The auxiliary wheel 21 is fixedly connected to the second ring gear 10, so the second ring gear 10 rotates with the auxiliary wheel 21. When the ratchet wheel 22 rotates in the opposite direction, the pawl 23 slides over the teeth of the ratchet wheel 22 and does not drive the auxiliary wheel 21 and the second ring gear 10 to rotate, thus achieving one-way rotation of the second ring gear 10.

[0058] Because the first gear ring 9 is sleeved on the outside of the crushing sleeve 5, and the first gear ring 9 and the second gear ring 10 are both rotatably connected to the upper end of the base plate 1, the first gear ring 9 and the second gear ring 10 are engaged through gears, so the unidirectional rotation of the second gear ring 10 will drive the first gear ring 9 to rotate, thereby making the crushing sleeve 5 sleeved in the first gear ring 9 realize intermittent rotation.

[0059] By setting up such a transmission mechanism and a one-way mechanism, the power generated by the driving motor 8 when the crushing assembly is working is utilized to realize the intermittent rotation of the crushing sleeve 5, so that the solid waste can be crushed at different positions in the crushing sleeve 5, thereby improving the uniformity and effect of the crushing, and further improving the working performance of the solid waste treatment device.

[0060] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
