Specific embodiments
[0033] The present utility model will be further described in detail below in conjunction with embodiments:
[0034] Embodiment 1
[0035] As Figures 1-6 shown, the present utility model provides a chain scraper feeding type continuous pyrolysis device, including an outer box 1 of the device and a conveying component 8.
[0036] Inside the outer box body 1 of the device, a pyrolysis chamber 2 is provided; a conveying assembly 8 is arranged inside the pyrolysis chamber 2; the conveying assembly 8 includes a driving motor II 801, a connecting rod 802, two first chain guides 803, a scraper drive chain 804, and two second chain guides 805; the output end of the driving motor II 801 is fixedly installed with a connecting rod 802, the surface of the connecting rod 802 is fixedly installed with two first chain guides 803, the surface of the two first chain guides 803 is rotatably connected with a scraper drive chain 804, and the other end of the scraper drive chain 804 is rotatably connected with two second chain guides 805.
[0037] In this embodiment, the conveying assembly 8 is arranged inside the pyrolysis chamber 2, so that the slag can be conveyed and pyrolyzed through the conveying assembly 8. A support frame is installed on one side of the outer box body 1 of the device, which can support the installation of the conveying assembly 8. The driving motor II 801 can be fixedly installed through the support frame. During use, the operation of the driving motor II 801 can drive the connecting rod 802 to rotate. At this time, the two first chain guides 803 fixedly installed on the connecting rod 802 rotate accordingly. At this time, both the two first chain guides 803 and the two second chain guides 805 rotate, and the connected scraper drive chain 804 can be driven to convey. And a plurality of scrapers are provided on the surface of the scraper drive chain 804. The plurality of scrapers can push and convey the slag when it falls onto the scraper drive chain 804, and the scrapers can push and convey more slag to avoid its accumulation.
[0038] As Figures 1-6 shown, in this embodiment, preferably, it further includes a burner 3 and a support frame body 4; the burner 3 is arranged at one end of the outer box body 1 of the device; the support frame body 4 is fixedly connected to one side of the outer box body 1. By starting the burner 3, the inside of the furnace of the device can be heated at a high temperature, so as to facilitate the pyrolysis treatment of the slag during the conveying process. The support frame body 4 is fixedly installed on one side of the outer box body 1 and is relatively firmly installed, and can support the installation of the feeding assembly 5, so that the feeding assembly 5 and the feeding hopper 6 can be used in cooperation.
[0039] As Figures 1-6As shown, preferably, it further includes a feeding component 5, which is arranged on the support frame 4; the feeding component 5 includes a driving motor 501, a feeding bin 502, a spiral feeding rod 503, and a feeding bin 504; the driving motor 501 is fixedly installed on one side of the feeding bin 502, the output end of the driving motor 501 is fixedly installed with a spiral feeding rod 503, and the top of the driving motor 501 is connected to the feeding bin 504 through penetration. The feeding component 5 is arranged on the support frame 4, and the support frame 4 can support and fix the installation of the feeding component 5. Before pyrolyzing the slag, the slag can be added through the feeding bin 504, and the driving motor 501 is started. The operation of the driving motor 501 can drive the spiral feeding rod 503 to rotate and cut the slag, and push and convey the slag during the cutting process of the slag, so that the slag is pushed and conveyed into the internal of the blanking bin 6. Since the blanking bin 6 communicates with the pyrolysis chamber 2, the cut slag can fall into the internal of the pyrolysis chamber 2 through the blanking bin 6, and the conveying component 8 is just located below the blanking bin 6, so that the fallen slag is transmitted and pyrolyzed through the conveying component 8.
[0040] As Figures 1-6 shown, preferably, it further includes a blanking bin 6 and a pyrolysis chamber manhole 7; the blanking bin 6 is installed through the top of the outer box body 1 of the device, and one end of the spiral feeding rod 503 is rotatably connected to the inner wall of the blanking bin 6; a pyrolysis chamber manhole 7 is installed through one end of the outer box body 1 of the device. By cooperating with the feeding component 5, the blanking bin 6 enables the cut slag to enter the internal of the blanking bin 6 through transportation after being cut by the feeding component 5. Since the internal of the blanking bin 6 communicates with the internal of the pyrolysis chamber 2, the transported slag enters the pyrolysis treatment through the pyrolysis chamber 2. The pyrolysis chamber manhole 7 is installed at one end of the outer box body 1 of the device and communicates with the internal of the pyrolysis chamber 2. By opening the pyrolysis chamber manhole 7, the internal of the pyrolysis chamber 2 can be observed, which is convenient for the later staff to maintain and clean the internal of the pyrolysis chamber 2.
[0041] As Figures 1-6As shown, preferably, it further includes a pyrolysis gas outlet 1, a flue gas outlet 10, and a slag discharge bin 11; the pyrolysis gas outlet 1 and the flue gas outlet 10 are respectively installed through the top of the outer box body 1 of the device; the top of the flue gas outlet 10 is connected to a heating gas channel 1001, and the other end of the heating gas channel 1001 is connected to a pyrolysis gas outlet 2 1002; a slag discharge bin 11 is installed on one side of the outer box body 1 of the device, and the slag discharge bin 11 communicates with the inside of the pyrolysis chamber 2; the pyrolysis gas outlet 2 1002 is installed through the top of the slag discharge bin 11. The pyrolysis gas outlet 1 communicates with the pyrolysis chamber 2, so that the pyrolysis gas generated by the internal pyrolysis of the pyrolysis chamber 2 can enter the inside of the pyrolysis gas outlet 1. Similarly, the pyrolysis gas and smoke can also enter through the inside of the flue gas outlet 10 and the pyrolysis gas outlet 2 1002. Since the flue gas outlet 10 is connected to the pyrolysis gas outlet 2 1002 through the heating gas channel 1001, and a delivery pipe is connected to one side of the heating gas channel 1001, and one end of the pyrolysis gas outlet 1 is also transported to the condensation system through a connecting pipe, the pyrolysis gas generated by pyrolysis enters the condensation system for treatment. At this time, the condensed liquid fuel can be stored in a tank, and the non-condensable waste gas at normal temperature separated is burned and utilized by the gas burner 3. The waste gas after combustion enters the desulfurization and dust removal system for harmless treatment of the waste gas and then is discharged, which can reduce pollution. The slag discharge bin 11 can transfer the pyrolyzed waste residue to the inside of the slag discharge bin 11 during the pyrolysis process of the slag material transmission. At this time, the waste residue can be discharged orderly through the slag discharger 12 at the bottom.
[0042] As Figures 1-6 shown, preferably, it further includes a slag discharger 12, and the slag discharger 12 is arranged at the bottom end of the slag discharge bin 11. After the slag material is pyrolyzed through the pyrolysis chamber 2, the waste residue formed after the pyrolysis of the slag material can be discharged orderly through the slag discharger 12, which is convenient for the subsequent treatment of the waste residue.
[0043] As Figures 1-6 shown, preferably, it further includes a plurality of furnace body support legs 13, and the plurality of furnace body support legs 13 are respectively installed at the bottom of the outer box body 1 of the device. The entire pyrolysis device can be used under the support of the plurality of furnace body support legs 13, and each furnace body support leg 13 is symmetrically installed below the pyrolysis device, so that the operation of the entire pyrolysis device is relatively stable.
[0044] Next, the working principle of the chain scraper feeding type continuous pyrolysis device will be specifically described.
[0045] As Figures 1-6As shown in the figure, during use, first add the slag through the feed bin 504, and turn on the burner 3 so that the burner 3 adds heat to the furnace. After the pyrolysis chamber 2 reaches the pyrolysis temperature, turn on the second driving motor 801, the first driving motor 501, and the slag discharge machine 12 at the same time. At this time, the slag can be cut and pushed by the spiral feeding rod 503 inside the feeding bin 502, so that the cut slag falls downward through the inside of the blanking bin 6 onto the surface of the scraper drive chain 804. At this time, the operation of the second driving motor 801 can drive the scraper drive chain 804 for transportation and transmission. At this time, it is necessary to adjust the running speed of the pyrolyzed slag in the pyrolysis chamber 2 according to the pyrolysis time from front to back. The slag is transported through the scraper drive chain 804 and pyrolyzed. After the slag is fully pyrolyzed, the ash will be continuously discharged from the slag discharge machine 12, realizing continuous production in a safe and orderly state. At this time, the pyrolysis gas generated during operation can enter the condensation system, the condensed liquid fuel is stored in the tank, and the non-condensable waste gas at normal temperature separated is burned and utilized in the furnace through the gas burner 3. The exhaust gas after combustion enters the desulfurization and dust removal system for harmless treatment of the exhaust gas and then is discharged. By setting the transmission component 8, a large amount of waste slag can be subjected to transmission pyrolysis treatment. The entire pyrolysis process can be continuously produced, which can improve the efficiency of waste slag pyrolysis and has a high production benefit.
[0046] The above text has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
