Description

Technical Field

[0001] The present application relates to the technical field of equipment for waste treatment, and more specifically, to a device for treating agricultural and forestry waste. Background Art

[0002] The anaerobic pyrolysis carbonization technology refers to placing waste in a carbonization device, using external heating in an oxygen-free environment to pyrolyze the organic matter in the waste into gas, and the generated gas is directly introduced into the incinerator to be fully burned, and the residue in the carbonization device is finally carbide and inorganic matter. The use of anaerobic pyrolysis carbonization technology to treat agricultural waste can reduce the generation of pollutants from the source, and at the same time facilitate the secondary utilization of waste. Therefore, there are treatment devices that use anaerobic pyrolysis carbonization technology to treat agricultural and forestry waste. For example, the patent document with the prior art publication number CN215799324U provides a continuous treatment device for agricultural and forestry waste using anaerobic pyrolysis carbonization, which uses a guide roller to guide the waste that is not in the correct position on the first conveyor belt to the correct direction, and uses a total collection pipe body and negative pressure equipment to extract the smoke inside the treatment equipment. Although the device has many beneficial effects, the following problems still exist: the sizes and shapes of various types of agricultural and forestry waste vary greatly. In this device, the agricultural and forestry waste is directly put into the processing equipment, which makes it difficult to ensure that wastes of different sizes and shapes can be processed at the same time. This method of processing is difficult and requires high technical capabilities of the equipment for anaerobic pyrolysis and carbonization. It is not conducive to the rapid and smooth processing of agricultural and forestry waste, and the completion of the processing of different wastes in sequence will greatly reduce the processing efficiency. Although CN215404022U can demolish larger agricultural and forestry wastes through demolition rods, it can only narrow the size gap to a certain extent, and still fails to properly solve the above problems. In view of this, we propose a device for processing agricultural and forestry wastes. Summary of the invention

DETAILED DESCRIPTION

[0028] See also Figure 1-6The device for processing agricultural and forestry waste in a preferred embodiment of this application document provides a technical solution:

[0029] A device for processing agricultural and forestry wastes, comprising a housing 1, such as Figure 1 As shown, a processing device body 3 is provided on one side of the shell 1, and a discharge port 101 is provided on the outer wall of the shell 1 near the processing device body 3. Figure 2 and Figure 3 A processing barrel 2 is provided in the shell 1, and a plurality of filter holes 201 are densely distributed on the outer wall of the processing barrel 2. A cutting assembly 7 is provided on one side of the processing barrel 2. The cutting assembly 7 includes a driving shaft 702 and a driving mechanism which are provided on one end face of the processing barrel 2 and extend to the inner cavity thereof. A plurality of cutting blades 706 are provided on the portion of the driving shaft 702 located in the inner cavity of the processing barrel 2. The driving mechanism can drive the driving shaft 702 to rotate. A feeding pipe 10 which is connected to the processing barrel 2 is provided on the other end face of the processing barrel 2. A conveyor belt 5 is provided on the lower side of the processing barrel 2. The conveyor belt 5 passes through the discharge port 101 and extends to the upper side of the processing equipment body 3.

[0030] In this embodiment, the agricultural waste to be processed is fed into the inner cavity of the processing barrel 2 through the feed pipe 10. The driving shaft 702, driven by the driving mechanism, drives the cutting blade 706 to rotate, thereby cutting and crushing the agricultural and forestry waste in the processing barrel 2. The crushed agricultural and forestry waste falls downward from the filter hole 201.

[0031] Specifically, Figure 4 As shown, the driving mechanism includes a mounting frame 704 fixedly arranged on one side of the processing barrel 2, a first gear 713 fixedly sleeved on the driving shaft 702 located on the outer side of the processing barrel 2, a driving shaft 708 is rotatably connected to the mounting frame 704, a first motor 705 is arranged on the mounting frame 704, a driving gear 709 is connected and fixed to the output end of the first motor 705, driving disks 715 with a symmetrical structure are arranged on both sides of the driving gear 709, one of the driving disks 715 is sleeved and fixed on the outer side of the driving shaft 708, a tooth groove 718 matched with the driving gear 709 is opened on the driving disk 715, the driving gear 709 is meshedly connected with the tooth groove 718, a second gear 710 is sleeved and fixed on the driving shaft 708, and the second gear 710 is meshedly connected with the first gear 713.

[0032] In this embodiment, under the action of the first motor 705, the driving gear 709 rotates and drives the driving plate 715 to drive the driving shaft 708 to rotate, and the second gear 710 follows the rotation. Since the second gear 710 is meshed and connected with the first gear 713, the driving shaft 702 will rotate under the drive of the first gear 713.

[0033] Furthermore, the cutting assembly 7 also includes a rapid filtration mechanism, which includes a drive sleeve 703 rotatably sleeved on the drive shaft 702 located on the outer side of the processing barrel 2 and fixedly connected to the processing barrel 2, and a driving mechanism, which can drive the drive sleeve 703 to rotate.

[0034] In this embodiment, the driving sleeve 703 can drive the processing barrel 2 to rotate under the drive of the driving mechanism, which can prevent the filter hole 201 from being blocked, effectively improve the falling efficiency of the cut and crushed agricultural and forestry waste, and improve the efficiency of processing agricultural and forestry waste.

[0035] Further, if Figure 4 As shown, the driving mechanism includes an active sleeve 707 rotatably connected to the mounting frame 704 and a third gear 712 sleeved and fixed on the outside of the driving sleeve 703, a driving plate 715 on the other side is sleeved and fixed on the outside of the active sleeve 707, and a fourth gear 719 is also sleeved and fixed on the outside of the active sleeve 707, and the fourth gear 719 is meshingly connected with the third gear 712.

[0036] In this embodiment, when the driving disk 715 on the other side rotates under the drive of the driving gear 709, the driving sleeve 707 will drive the fourth gear 719 to rotate. Since the fourth gear 719 is meshed with the third gear 712, the fourth gear 719 will drive the driving sleeve 703 and the processing barrel 2 to rotate.

[0037] Furthermore, the diameter of the second gear 710 is larger than the diameter of the first gear 713 , and the diameter of the fourth gear 719 is smaller than the diameter of the third gear 712 .

[0038] In this embodiment, the purpose of such a configuration is to enable the cutting blade 706 to maintain high-speed rotation, so as to facilitate the rapid cutting and crushing of agricultural and forestry waste, while the processing barrel 2 can maintain a relatively low-speed rotation, which can not only allow the cut and crushed agricultural and forestry waste to quickly pass through the filter hole 201, but also prevent the cut and crushed agricultural and forestry waste in the processing barrel 2 from splashing everywhere.

[0039] It is worth noting that see Figure 5 The rapid filtration mechanism also includes an oscillating mechanism, which includes a driving block 714 and a lifting mechanism arranged on the outside of the processing barrel 2. The lifting mechanism can drive the driving block 714 to move up and down.

[0040] In this embodiment, under the action of the lifting mechanism, the driving block 714 will drive the processing barrel 2 to oscillate up and down, further improving the efficiency of agricultural and forestry waste passing through the filter hole 201.

[0041] It is worth noting that Figure 5As shown, the lifting mechanism includes a fixed frame 701 arranged on the outside of the driving block 714 and connected and fixed to the shell 1, and a counterweight block 717 arranged on the processing barrel 2. The driving block 714 is limited by the fixed frame 701 and is slidably connected to the fixed frame 701. The upper and lower end surfaces of the driving block 714 are provided with a plurality of first springs 716 connected and fixed to the fixed frame 701. The driving block 714 on one side is connected and fixed to the feed pipe 10, and the driving block 714 on the other side is connected and fixed to the mounting frame 704.

[0042] In this embodiment, as the processing barrel 2 rotates, the counterweight block 717 rotates accordingly, and under the limiting effect of the fixing frame 701 and the restoring effect of the first spring 716, the driving block 714 will drive the processing barrel 2 to oscillate up and down.

[0043] Further, combined with Figure 2 and Figure 6 As can be seen, the conveyor belt 5 is densely covered with multiple leakage holes 501, a drain pipe 4 is provided on one side of the shell 1, a material guide plate 6 with a symmetrical structure is provided on the lower side of the processing barrel 2, and an extrusion assembly 9 is provided on the lower side of the material guide plate 6. The extrusion assembly 9 includes two extrusion rollers 901 and a rotating mechanism, and the rotating mechanism can drive the two extrusion rollers 901 to rotate towards each other.

[0044] In this embodiment, the cut and pulverized agricultural and forestry waste enters between the two squeezing rollers 901 under the action of the guide plate 6. Under the action of the rotating mechanism, the squeezing rollers 901 rotate in opposite directions, which can squeeze the agricultural and forestry waste and remove part of the moisture contained in the agricultural and forestry waste, thereby further improving the efficiency of agricultural and forestry waste treatment and effectively reducing the energy consumption required for agricultural and forestry waste treatment.

[0045] Furthermore, the rotating mechanism includes a second motor 905 arranged on the outside of the shell 1, and the output end of the second motor 905 is connected and fixed with a first rotating shaft 903 connected and fixed with one of the squeezing rollers 901, and a second rotating shaft 904 is provided on the other squeezing roller 901, and a fifth gear 906 is sleeved and fixed on the first rotating shaft 903 and the second rotating shaft 904, and the two fifth gears 906 are meshingly connected.

[0046] In this embodiment, under the action of the second motor 905, the first rotating shaft 903 will drive the fifth gear 906 on its upper side and the corresponding squeezing roller 901 to rotate. Since the two fifth gears 906 are meshed and connected, the fifth gear 906 on the other side will drive the second rotating shaft 904 and the corresponding squeezing roller 901 to rotate.

[0047] Furthermore, an extrusion sleeve 902 is provided on the outer side of the extrusion roller 901 , and a plurality of second springs 907 are provided between the extrusion sleeve 902 and the extrusion roller 901 .

[0048] In this embodiment, the purpose of providing the squeezing sleeve 902 and the second spring 907 is to enable the device to squeeze agricultural and forestry wastes while preventing the squeezing roller 901 from being damaged by the wastes that are too hard.

[0049] In addition, a scraper 8 is provided on the lower side of the extrusion sleeve 902 , and the upper side of the scraper 8 is in frictional contact with the extrusion sleeve 902 .

[0050] In this embodiment, as the squeezing roller 901 drives the squeezing sleeve 902 to rotate, the scraper 8 can scrape off the agricultural and forestry waste adhered to the squeezing sleeve 902 due to the frictional contact between the upper side of the scraper 8 and the squeezing sleeve 902, thereby ensuring the squeezing and dewatering effect of the device.

[0051] It should be noted that the mixing mechanism inside the extrusion roller 901 includes a carrier plate that slidably cooperates with the inner wall of the extrusion roller 901, and a plurality of mixing rods are provided on the carrier plate. The two ends of the extrusion roller 901 are rotatably connected to a feed pipe and a discharge pipe.

[0052] In this embodiment, the medium, reagents, etc. required in the processing process are input into the extrusion roller 901 for mixing through the feeding pipe. As the extrusion roller 901 rotates, the mixing mechanism inside the extrusion roller 901 is always at the inner bottom of the extrusion roller 901 under the action of friction and gravity and shakes to a certain extent, thereby mixing the medium, reagents, etc. evenly and achieving a better mixing effect.

[0053] When relevant staff need to use this device to process agricultural and forestry waste, first, the agricultural waste to be processed is put into the inner cavity of the processing barrel 2 through the feed pipe 10. Under the action of the first motor 705, the driving gear 709 rotates and drives the driving plate 715 to drive the driving shaft 708 to rotate, and the second gear 710 follows the rotation. Since the second gear 710 is meshed and connected with the first gear 713, the driving shaft 702 will drive the cutting blade 706 to rotate under the drive of the first gear 713, and the agricultural and forestry waste in the processing barrel 2 is cut and crushed. The crushed agricultural and forestry waste falls downward from the filter hole 201.

[0054] During this process, when the driving disk 715 on the other side rotates under the drive of the driving gear 709, the driving sleeve 707 will drive the fourth gear 719 to rotate. Since the fourth gear 719 is meshed with the third gear 712, the fourth gear 719 will drive the driving sleeve 703 and the processing barrel 2 to rotate to prevent the filter hole 201 from being blocked.

[0055] At the same time, as the processing barrel 2 rotates, the counterweight block 717 rotates accordingly. Under the limiting effect of the fixing frame 701 and the restoring effect of the first spring 716, the driving block 714 will drive the processing barrel 2 to oscillate up and down, further improving the efficiency of agricultural and forestry waste passing through the filter hole 201.

[0056] The cut and shredded agricultural and forestry waste enters between the two squeezing rollers 901 under the action of the guide plate 6. Under the action of the second motor 905, the first rotating shaft 903 will drive the fifth gear 906 on its upper side and the corresponding squeezing roller 901 and squeezing sleeve 902 to rotate. Since the two fifth gears 906 are meshed and connected, the fifth gear 906 on the other side will drive the second rotating shaft 904 and the corresponding squeezing roller 901 and squeezing sleeve 902 to rotate, thereby squeezing the agricultural and forestry waste and removing some of the moisture contained in the agricultural and forestry waste.

[0057] The pre-treated agricultural and forestry waste falls to the top surface of the conveyor belt 5 under the action of gravity, and the moisture leaks out from the leakage hole 501, and is transported to the processing equipment body 3 for subsequent processing under the action of the conveyor belt 5.
