[0029] Next, in conjunction with the drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

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

[0031] As 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] Adopting the above solution: The starting motor 42 drives the output shaft to drive the rotating plate 43 to rotate circumferentially. Under the clockwise rotation of the rotating plate 43, the rotating plate 43 drives the transmission plate 44 through the first transmission rod 441. The transmission plate 44 drives the sliding plate 45, the second scissors block 47, and the reciprocating plate 48 downward through the transmission of the second transmission rod 451. The sliding plate 45 and the second scissors block 47 slide downward at the sliding port 464. Through the reciprocating power of the rotating plate 43, the second scissors block 47 quickly shears the waste.

[0039] As Figure 6 As shown in the figure, a shearing box 46 is connected to the upper part of one side of the low-temperature thermal decomposition bin 1. An inclined slideway 461 is arranged inside the shearing box 46. A guide block 462 is fixedly connected to the upper wall of the inclined slideway 461. A first scissors block 463 is fixedly connected to one side surface of the guide block 462. A sliding port 464 is arranged inside one side of the inclined slideway 461. A plurality of reciprocating grooves 465 are connected equidistantly along the width direction on one side surface of the sliding port 464.

[0040] Adopting the above solution: It is beneficial to guide the waste to the shearing position through the inclined slideway 461.

[0041] As Figure 7 As shown in the figure, a second scissors block 47 is fixedly connected to the upper part of the sliding plate 45. A plurality of reciprocating plates 48 are connected equidistantly along the width direction on the upper part of one side surface of the sliding plate 45. The sliding plate 45 and the second scissors block 47 are slidably matched inside the sliding port 464. The reciprocating plate 48 is slidably matched inside the reciprocating groove 465. The lower end surface of the first scissors block 463 is directly opposite to the upper end surface of the second scissors block 47.

[0042] Adopting the above solution: After the reciprocating plate 48 slides downward inside the reciprocating groove 465, the rotating plate 43 has rotated more than half clockwise. When it continues to rotate, the power of the pushing plate 283 changes from downward to upward, causing the sliding plate 45, the second scissors block 47, and the reciprocating plate 48 to move upward. During the upward movement of the second scissors block 47, it cooperates with the first scissors block 463 to shear the waste pushed by the pushing plate 283. Utilizing the high-speed operation of the motor 42, the volume of the sheared waste becomes smaller, making the volume of the waste uniform. After shearing, the waste will fall on one side of the inner bottom surface of the inclined slideway 461. To prevent the sheared waste from remaining on one side of the inner bottom surface of the inclined slideway 461, through the cooperation of the reciprocating plate 48 and the reciprocating groove 465, under the high-speed reciprocating movement of the reciprocating plate 48 and the inclined surface on the reciprocating plate 48, the remaining waste will fall into the low-temperature thermal decomposition bin 1. It can effectively shear waste of different sizes into uniform sizes, enabling the waste to be heated evenly and the decomposition speed to increase, thereby improving the treatment effect of the waste. Among them, after 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 waste sheared off can be pushed towards the inside of the low-temperature thermal decomposition bin 1 and dropped, avoiding the waste remaining on one side of the inclined slideway 461;

[0044] Such as Figure 6 As shown, one side of the closing plate 33 closes at the port where the shearing box 46 communicates with the low-temperature thermal decomposition bin 1, and the other port of the shearing box 46 is obliquely facing one side of the waste material hopper 27.

[0045] Adopting the above scheme: it is beneficial to the work of automatically opening and closing, without manual operation, saving time and increasing the work progress.

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

[0047] First of all, the worker loads the waste into the inside of the waste material hopper 27 through tools. At this time, the waste material hopper 27 is in a horizontal state. After the waste is filled, the first hydraulic cylinder 22 is started to drive the output rod 23 upward. The connecting frame 24 is stressed and drives the sliding track 26 and the waste material hopper 27 to move upward through the rotating rod 251 and the T-shaped plate 25. The waste material hopper 27 slides vertically upward inside the first guide rail plate 273 and the second guide rail plate 274 by using the first sliding rod 271 and the second sliding rod 272 on both sides. After the waste material hopper 27 moves upward for a certain distance, the second sliding rod 272 touches the inner top wall of the second guide rail plate 274. Taking the second sliding rod 272 as the center point, under the continuous output of the first hydraulic cylinder 22, the T-shaped plate 25 slides to one side inside the T-shaped groove 261. The other side of the waste material hopper 27 is stressed, and taking the second sliding rod 272 as the center point, the first sliding rod 271 gradually rotates clockwise in the upper part of the inner side of the first guide rail plate 273. As the waste material hopper 27 rotates clockwise, among them, the first hydraulic cylinder 22 also rotates with the rotation of the waste material hopper 27 on the rotating frame 21 until the rotation angle of the waste material hopper 27 is parallel to the angle of the inclined slideway 461, such as Figure 6 As shown, stop the first hydraulic cylinder 22.

[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. The closing plate 33 slides upward in the closing groove 34, gradually opening the port where the shearing box 46 communicates with the low-temperature thermal decomposition bin 1.

[0049] Then, start the second hydraulic cylinder 281 to drive the pushing rod 282 to move to one side. The pushing plate 283 is forced to push the loaded waste to move to one side. The pushed waste falls onto the inner bottom surface of the inclined chute 461. With continuous pushing, it is pushed to the first shear block 463 and the second shear block 47. While the pushing plate 283 is pushing, start the motor 42 to drive the output shaft to drive the rotating plate 43 to rotate circumferentially. Under the clockwise rotation of the rotating plate 43, the rotating plate 43 drives the transmission plate 44, the second transmission rod 451, the sliding plate 45, the second shear block 47, and the reciprocating plate 48 downward through the first transmission rod 441. The sliding plate 45 and the second shear block 47 are forced to slide downward at the sliding port 464. Among them, the reciprocating plate 48 also slides downward inside the reciprocating groove 465. After the rotating plate 43 rotates clockwise more than half, change the downward power of the pushing plate 283 to upward power, so that the sliding plate 45, the second shear block 47, and the reciprocating plate 48 move upward. During the upward movement of the second shear block 47, it cooperates with the first shear block 463 (as Figure 6 shown), and the waste pushed by the pushing plate 283 can be sheared. By using the high-speed operation of the motor 42, the volume of the sheared waste is reduced, so that the volume of the waste is uniform. After the waste is sheared, it will fall on one side of the inner bottom surface of the inclined chute 461. Through the high-speed reciprocating movement of the reciprocating plate 48 up and down and the inclined surface on the reciprocating plate 48, the remaining waste falls into the interior of the low-temperature thermal decomposition chamber 1.

[0050] Then, start the first hydraulic cylinder 22 to move downward, so that the waste hopper 27 returns to its original position. Moreover, it also drives the closing plate 33 to slide downward inside the closing groove 34, and gradually closes the port where the shear box 46 communicates with the low-temperature thermal decomposition chamber 1 for sealing. Then, start the ignition device, the air magnetization device, the tail gas treatment device, etc. to work in sequence.
