[0002] Low-temperature pyrolysis of waste is a treatment technology that heats solid waste to a certain temperature under oxygen-free or oxygen-deficient conditions to cause it to decompose. In this process, the organic components in the waste are converted into products such as combustible gas, liquid fuel and coke.

[0003] The existing waste treatment device transports the waste to the interior of the low-temperature thermal decomposition bin through a hopper and then performs low-temperature thermal treatment. However, the waste transported has different volumes, which causes uneven heating of the waste, thereby reducing the waste treatment effect.

[0004] Therefore, a low-temperature pyrolysis waste treatment device is proposed to address the above problems. Summary of the invention

[0008] The cam is connected with the first hydraulic cylinder through the fixed shaft, and the output end of the first hydraulic cylinder is connected with the output rod, and the upper end of the output rod is connected with the connecting frame. The connecting frame is connected with a T-shaped plate through the rotating rod. The T-shaped plate is slidably matched with a sliding rail. A T-shaped slot is provided inside the sliding rail, and the T-shaped plate is slidably matched inside the T-shaped slot. A waste material bucket is fixedly connected with the upper end surface of the sliding rail, and both sides of the waste material bucket are fixedly connected with the first sliding rod and the second sliding rod. One end of the first sliding rod is slidably matched with the first guide rail plate, and the lower end surface of the first guide rail plate is fixedly connected to one side of the upper end surface of the bottom plate, and one end of the second sliding rod is slidably matched with the second guide rail plate, and the lower end surface of the second guide rail plate is fixedly connected to one side of the upper end surface of the bottom plate.

[0009] A support plate is fixedly connected to one side wall of the waste material hopper, a second hydraulic cylinder is fixedly connected to the upper end of the support plate, a push rod is connected to the output end of the hydraulic cylinder, one end of the push rod is fixedly connected to the push plate, and one end of the push rod extends through the interior of the waste material hopper, and the push plate is located on one side of the interior of the waste material hopper.

[0010] The automatic closing mechanism includes a rotating sleeve fixedly rotating at one end of the second sliding rod, a connecting rod fixedly connected to the upper outer side of the rotating sleeve, a closing plate fixedly connected to one end of the connecting rod, and a closing groove slidingly matched on the closing plate, which is opened on one side of the upper end surface of the low-temperature thermal decomposition chamber.

[0011] The shearing mechanism includes a support frame fixedly connected to the lower part of a side of the low-temperature thermal decomposition chamber, one side of the support frame is fixedly connected to a motor, the motor is rotated through an output shaft and is matched with a rotating plate, the rotating plate is connected to a transmission plate through a first transmission rod, and the upper part of the transmission plate is connected to a sliding plate through a second transmission rod.

[0012] A shear box is connected to the upper part of one side surface of the low-temperature thermal decomposition chamber, an inclined slide is provided inside the shear box, a guide block is fixedly connected to the upper wall of the inclined slide, a first scissors block is fixedly connected to one side of the guide block, a sliding opening is provided inside one side of the inclined slide, and reciprocating grooves are equidistantly connected to one side of the sliding opening along the width direction.

[0013] A second scissors block is fixedly connected to the upper part of the sliding plate, and a reciprocating plate is equidistantly connected to the upper part of one side surface of the sliding plate along the width direction. The sliding plate and the second scissors block are slidably fitted inside the sliding opening, and the reciprocating plate is slidably fitted inside the reciprocating groove.

[0016] The present invention, through the provision of the first guide rail plate and the second guide rail plate, is conducive to not only allowing the waste material bucket to move vertically upward, but also maintaining the waste material bucket in a horizontal state without a tilted state. During the movement, the waste material bucket can also be converted into an inclined state to dock with the inclination angle of the inclined slide, thereby improving working performance and multifunctionality.

[0017] In order to solve the problem, the present invention is provided with a rotating sleeve. When the second sliding rod rotates by itself, it can rotate inside the rotating sleeve without affecting the connecting rod and the closing plate. Secondly, the closing plate slides upward in the closing groove, gradually opening the port where the shear box communicates with the low-temperature thermal decomposition chamber 1, which is conducive to automatic opening and closing, without manual operation, saving time and increasing work progress.

[0018] The present invention prevents the waste from remaining in the waste material hopper through the pushing of the pushing plate, and further provides power in the shearing direction, thereby avoiding blockage at the shearing position and improving fluidity.

[0019] The present invention can effectively shear wastes of different sizes into uniform sizes through the shearing of the second scissor block and the first scissor block, so that the wastes can be heated evenly and the decomposition speed is increased, thereby improving the waste treatment effect. Among them, after the volume of the waste is reduced, the amount of waste loaded is increased.

[0020] The present invention can push the sheared waste to the inside of the low-temperature thermal decomposition bin through the reciprocating motion of the reciprocating plate and the reciprocating groove, thereby preventing the waste from being left on one side of the inclined slideway.

DETAILED DESCRIPTION

[0029] The following will be used in conjunction with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1 , Figure 2 As shown, the present invention provides a low-temperature pyrolysis waste treatment device, including a low-temperature pyrolysis bin 1, a bottom plate 11 is fixedly connected to the upper part of one side of the low-temperature pyrolysis bin 1, and an automatic feeding mechanism 2 is arranged on the upper part of the bottom plate 11; an automatic closing mechanism 3 is arranged on the upper part of the low-temperature pyrolysis bin 1; and a shearing mechanism 4 is arranged on the upper part of one side of the low-temperature pyrolysis bin 1.

[0031] like Figure 2 , Figure 3As shown, the automatic feeding mechanism 2 includes a rotating frame 21, the lower end of which is fixedly connected to the upper end surface of the bottom plate 11, and the rotating frame 21 is connected to a first hydraulic cylinder 22 through a fixed shaft, the output end of the first hydraulic cylinder 22 is connected to an output rod 23, the upper end of the output rod 23 is connected to a connecting frame 24, the connecting frame 24 is connected to a T-shaped plate 25 through a rotating rod 251, the T-shaped plate 25 is slidably matched with a sliding track 26, the sliding track 26 is provided with a T-shaped slot 261, the T-shaped plate 25 is slidably matched with the T-shaped plate 25, and the T-shaped plate 25 is slidably matched with the T-shaped plate 25. Inside the groove 261, the upper end surface of the sliding track 26 is fixedly connected to a waste material bucket 27, and the first sliding rod 271 and the second sliding rod 272 are fixedly connected on both sides of the waste material bucket 27. One end of the first sliding rod 271 is slidably matched with a first guide rail plate 273, and the lower end surface of the first guide rail plate 273 is fixedly connected to one side of the upper end surface of the bottom plate 11. One end of the second sliding rod 272 is slidably matched with a second guide rail plate 274, and the lower end surface of the second guide rail plate 274 is fixedly connected to one side of the upper end surface of the bottom plate 11.

[0032] The above scheme is adopted: the first hydraulic cylinder 22 is started to drive the output rod 23 upward, and the connecting frame 24 is driven by the force through the rotating rod 251 and the T-plate 25 to move the sliding track 26 and the waste material bucket 27 upward. The waste material bucket 27 uses the first sliding rod 271 and the second sliding rod 272 on both sides to vertically move upward along the inside of the first guide rail plate 273 and the second guide rail plate 274, effectively making the waste material bucket 27 remain parallel when moving upward. After the waste material bucket 27 moves upward a certain distance, the second sliding rod 272 contacts the inner top wall of the second guide rail plate 274, making the second sliding rod 272 the center point of the circle, and then under the continued output of the first hydraulic cylinder 22, the T-plate 25 slides to one side inside the T-slot 261, so that the waste material bucket 27 can move upward. The other side of the material bucket 27 is subjected to force, and the center point of the second sliding rod 272 is used to make the first sliding rod 271 move along the inner upper part of the first guide rail plate 273, so that the waste material bucket 27 gradually rotates clockwise, wherein the first hydraulic cylinder 22 also rotates on the rotating frame 21 along with the rotation of the waste material bucket 27, until the rotation angle of the waste material bucket 27 is parallel to the angle of the inclined slide 461, and the first hydraulic cylinder 22 is stopped, which is conducive to not only allowing the waste material bucket 27 to move vertically upward, but also maintaining the waste material bucket 27 in a horizontal state without a tilted state. During the movement, the waste material bucket 27 can also be transformed into an inclined state to dock with the tilt angle of the inclined slide 461, thereby improving the working performance and multifunctionality.

[0033] like Figure 4As shown, a support plate 28 is fixedly connected to one side wall of the waste material hopper 27, and a second hydraulic cylinder 281 is fixedly connected to the upper end of the support plate 28. A push rod 282 is connected to the output end of the hydraulic cylinder 281, and one end of the push rod 282 is fixedly connected to a push plate 283, and one end of the push rod 282 extends through the interior of the waste material hopper 27, and the push plate 283 is located on one side of the interior of the waste material hopper 27.

[0034] The above scheme is adopted: the second hydraulic cylinder 281 is started to drive the pushing rod 282 to move to one side, and the pushing plate 283 is forced to push the loaded waste to one side along the inside of the waste material bucket 27, and the pushed waste falls onto the inner bottom surface of the inclined slide 461, and then continues to be pushed. Through the pushing of the pushing plate 283, the loaded waste is prevented from remaining in the inside of the waste material bucket 27. Moreover, by providing power in the shearing direction, blockage at the shearing position can be avoided, thereby improving smoothness.

[0035] like Figure 3 , Figure 6 As shown, the automatic closing mechanism 3 includes a rotating sleeve 31 fixedly rotating at one end of the second sliding rod 272, a connecting rod 32 is fixedly connected to the upper outer side of the rotating sleeve 31, and a closing plate 33 is fixedly connected to one end of the connecting rod 32. The closing plate 33 is slidably matched with a closing groove 34, and the closing groove 34 is opened on one side of the upper end surface of the low-temperature thermal decomposition chamber 1.

[0036] The above scheme is adopted: the second sliding rod 272 drives the rotating sleeve 31, the connecting rod 32, and the closing plate 33 to move upward. Firstly, in order to avoid the second sliding rod 272 from self-rotating when the second sliding rod 272 is the center point, which causes the closing plate 33 to be unable to open and close normally, in order to solve the problem, a rotating sleeve 31 is provided. When the second sliding rod 272 self-rotates, it can rotate inside the rotating sleeve 31 without affecting the connecting rod 32 and the closing plate 33. Secondly, the closing plate 33 slides upward in the closing groove 34, gradually opening the port where the shear box 46 communicates with the low-temperature thermal decomposition chamber 1.

[0037] like Figure 5 As shown, the shearing mechanism 4 includes a support frame 41 fixedly connected to the lower part of a side of the low-temperature thermal decomposition chamber 1, and a motor 42 is fixedly connected to one side of the support frame 41. The motor 42 is rotated through the output shaft and is matched with a rotating plate 43. The rotating plate 43 is connected to a transmission plate 44 through a first transmission rod 441, and the upper part of the transmission plate 44 is connected to a sliding plate 45 through a second transmission rod 451.

[0038] The above scheme is adopted: the starting motor 42 drives the output shaft to drive the rotating plate 43 to rotate in a circle. When the rotating plate 43 rotates clockwise, the rotating plate 43 is transmitted to the transmission plate 44 through the first transmission rod 441. The transmission plate 44 is driven downward by the sliding plate 45, the second scissor block 47, and the reciprocating plate 48 through the transmission of the second transmission rod 451. The sliding plate 45 and the second scissor block 47 are forced to slide downward at the sliding opening 464. The reciprocating power of the rotating plate 43 enables the second scissor block 47 to quickly shear the waste.

[0039] like Figure 6 As shown, a shear box 46 is connected to the upper part of one side surface of the low-temperature thermal decomposition chamber 1, and an inclined slide 461 is provided inside the shear box 46. A guide block 462 is fixedly connected to the upper wall of the inclined slide 461, and a first scissors block 463 is fixedly connected to one side of the guide block 462. A sliding opening 464 is provided inside one side of the inclined slide 461, and a reciprocating groove 465 is equidistantly connected to one side of the sliding opening 464 along the width direction.

[0040] The above solution is adopted to facilitate the movement of waste to the shearing position through the guidance of the inclined slide 461 .

[0041] like Figure 7 As shown, the second scissor block 47 is fixedly connected to the upper part of the sliding plate 45, and a reciprocating plate 48 is equidistantly connected to the upper part of one side surface of the sliding plate 45 along the width direction. The sliding plate 45 and the second scissor block 47 are slidably fitted inside the sliding opening 464, and the reciprocating plate 48 is slidably fitted inside the reciprocating groove 465. The lower end surface of the first scissor block 463 is opposite to the upper end surface of the second scissor block 47.

[0042] The above scheme is adopted: after the reciprocating plate 48 slides downward inside the reciprocating groove 465, its rotating plate 43 has rotated clockwise for more than half, and the downward power of the pushing plate 283 is changed to upward power under continued rotation, so that the sliding plate 45, the second scissor block 47, and the reciprocating plate 48 move upward, and the second scissor block 47 cooperates with the first scissor block 463 during the upward movement to shear the waste pushed by the pushing plate 283, and the high-speed operation of the motor 42 is used to reduce the volume of the sheared waste, so that the volume of the waste can be any size. The sheared waste will fall on one side of the bottom surface of the inclined slide 461. In order to prevent the sheared waste from remaining on one side of the bottom surface of the inclined slide 461, through the cooperation of the reciprocating plate 48 and the reciprocating groove 465, the reciprocating plate 48 moves up and down at a high speed and the inclined surface of the reciprocating plate 48, so that the remaining waste falls into the interior of the low-temperature thermal decomposition chamber 1. It can effectively cut wastes of different sizes into uniform sizes, allow the wastes to be heated evenly, and decompose faster, thereby improving the waste treatment effect. Among them, when the volume of the waste becomes smaller, the amount of waste loaded increases.

[0043] Through the reciprocating motion of the reciprocating plate 48 and the reciprocating groove 465, the sheared waste can be pushed to the inside of the low-temperature thermal decomposition chamber 1 to avoid the waste being left on one side of the inclined slide 461.

[0044] like Figure 6 As shown, one side of the closing plate 33 is closed at the port of the shear box 46 communicating with the low-temperature thermal decomposition chamber 1 , and the other side port of the shear box 46 is tilted and facing one side of the waste material hopper 27 .

[0045] The above scheme is adopted: it is conducive to the work of automatic opening and closing, without the need for manual operation, saving time and increasing work progress.

[0046] The working principle and use process of the present invention:

[0047] First, the worker uses tools to load the waste into the waste material bucket 27. At this time, the waste material bucket 27 is horizontal. After the waste is fully loaded, the first hydraulic cylinder 22 is started to drive the output rod 23 upward. The connecting frame 24 is driven by the rotating rod 251 and the T-plate 25 to move the sliding rail 26 and the waste material bucket 27 upward. The waste material bucket 27 uses the first sliding rod 271 and the second sliding rod 272 on both sides to slide vertically upward inside the first guide rail plate 273 and the second guide rail plate 274. After the waste material bucket 27 moves upward a certain distance, the second sliding rod 272 pushes against the first guide rail plate 273 and the second guide rail plate 274. The inner top wall of the second guide rail plate 274 is made the second sliding rod 272 as the center point, and under the continued output of the first hydraulic cylinder 22, the T-plate 25 slides to one side inside the T-slot 261, and the other side of the waste material bucket 27 is subjected to force, and the center point of the second sliding rod 272 is used to make the first sliding rod 271 gradually rotate clockwise on the inner upper part of the first guide rail plate 273, and the waste material bucket 27 rotates clockwise, wherein the first hydraulic cylinder 22 also rotates on the rotating frame 21 with the rotation of the waste material bucket 27, until the rotation angle of the waste material bucket 27 is parallel to the angle of the inclined slide 461, as shown in FIG. Figure 6 As shown, the first hydraulic cylinder 22 is stopped.

[0048] At the same time, the second sliding rod 272 drives the rotating sleeve 31, the connecting rod 32, and the closing plate 33 to move upward, and the closing plate 33 slides upward in the closing groove 34, gradually opening the port where the shear box 46 communicates with the low-temperature thermal decomposition chamber 1.

[0049] The second hydraulic cylinder 281 is then started to drive the push rod 282 to move to one side. The push plate 283 is pushed to one side by the force to push the loaded waste to one side. The pushed waste falls onto the inner bottom surface of the inclined slide 461, and then continues to push to the first scissor block 463 and the second scissor block 47. While the push plate 283 is pushing, the motor 42 is started to drive the output shaft to drive the rotating plate 43 to rotate in a circle. Under the clockwise rotation of the rotating plate 43, the rotating plate 43 is driven downward on the transmission plate through the first transmission rod 441. 44, second transmission rod 451, sliding plate 45, second scissor block 47, reciprocating plate 48, the sliding plate 45 and the second scissor block 47 are forced to slide downward on the sliding passage 464, wherein the reciprocating plate 48 also slides downward inside the reciprocating groove 465, after the rotating plate 43 rotates more than half clockwise, the downward force of the pushing plate 283 is changed to the upward force, so that the sliding plate 45, the second scissor block 47, and the reciprocating plate 48 move upward, and the second scissor block 47 cooperates with the first scissor block 463 in the upward movement (such as Figure 6 As shown), the waste pushed by the shearing push plate 283 can be sheared, and the high-speed operation of the motor 42 can reduce the volume of the sheared waste, so that the volume of the waste can be any size. The sheared waste will fall on one side of the bottom surface of the inclined slide 461, and the remaining waste will fall into the interior of the low-temperature thermal decomposition chamber 1 through the high-speed up and down reciprocating movement of the reciprocating plate 48 and the inclined surface of the reciprocating plate 48.

[0050] The first hydraulic cylinder 22 is started up again to move downward, so that the waste material bucket 27 returns to its original position, and the closing plate 33 is also driven to slide downward inside the closing groove 34, gradually closing at the port where the shear box 46 communicates with the low-temperature thermal decomposition chamber 1, and then the ignition device, the air magnetization device, the exhaust gas treatment device, etc. are started up in sequence.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
