Abstract
Description
Technical Field
[0001] This application relates to the field of sludge agricultural waste treatment, and in particular to a sludge agricultural waste co-treatment device. Background Technology
[0002] Sludge contains large amounts of organic matter, heavy metals, pathogens, and other harmful substances. Improper handling not only occupies vast amounts of land resources but can also cause serious pollution to soil, water, and air, threatening ecological balance and human health. Meanwhile, the large amounts of waste generated during agricultural production, such as crop straw and livestock manure, also face disposal challenges. Statistics show that my country produces over 1 billion tons of crop straw and approximately 4 billion tons of livestock manure annually. If these agricultural wastes are arbitrarily dumped or burned, they will not only waste resources but also cause environmental pollution and safety hazards.
[0003] Currently, the main methods for treating sludge include landfill, incineration, and composting. However, both sludge and agricultural waste contain usable elements, which can be mixed with combustion aids to obtain biofuel. However, in the process of treating sludge and agricultural waste in traditional co-processing devices, the mixing effect of sludge and agricultural waste is poor because sludge and agricultural waste are often solidified, resulting in unreliable composition of the mixture. Utility Model Content
[0004] In order to improve the problem that traditional sludge agricultural waste co-processing devices often have poor mixing and stirring effects with combustion aids during the treatment of sludge agricultural waste, which is often in solid form, resulting in unreliable composition of the mixture, this application provides a sludge agricultural waste co-processing device.
[0005] The sludge agricultural waste co-treatment device provided in this application adopts the following technical solution:
[0006] A sludge-agricultural waste co-treatment device includes a sludge-agricultural waste co-treatment tank, a sludge-agricultural waste co-treatment tank cover installed at the top of the tank, a feeding chamber connected to one end of the cover, a plug-in cavity opened at one end of the feeding chamber, a connecting block movably connected inside the plug-in cavity, and crushing blades installed at equal intervals at one end of the connecting block, a discharge solenoid valve provided at the bottom of the sludge-agricultural waste co-treatment tank, and a base installed at the bottom of the tank.
[0007] By adopting the above technical solution, the connecting block and the crushing blades circulate left and right, thereby enabling the crushing blades to crush the sludge and agricultural waste put into the feeding chamber, so as to ensure better subsequent heating and mixing effect.
[0008] Preferably, the sludge agricultural waste co-processing tank is equipped with an electric heating tube inside the tank body, and the two ends of the electric heating tube are respectively connected to the output end and the input end of the electric heater.
[0009] By adopting the above technical solution, the heating operation is completed by using an electric heating element in conjunction with an electric heater.
[0010] Preferably, a first motor is installed at the top of the sludge-agricultural waste co-processing tank cover, and the output end of the first motor passes through the interior of the sludge-agricultural waste co-processing tank cover and is connected to the top of the transmission column. An auger plate is installed on the outer wall of the transmission column.
[0011] By adopting the above technical solution and using the auger blades, the auger blades can drive the mixture at the bottom of the sludge and agricultural waste co-processing tank to turn upwards during use, thereby effectively ensuring uniform heating.
[0012] Preferably, mounting frames are symmetrically installed on both sides of the transmission column, and a mixing plate is installed inside the mounting frame. The mixing plate has several through holes, and a silicone scraper is installed at one end of the mounting frame.
[0013] By adopting the above technical solution, the inner wall of the sludge agricultural waste co-processing tank is scraped off with a silicone scraper, which reduces the waste of resources and avoids hindering the heating effect.
[0014] Preferably, guide grooves are installed on both outer walls of the feeding chamber, and guide sliders are movably connected through the inside of the guide grooves. The guide sliders are installed on the inner walls of both sides of the mounting frame.
[0015] By adopting the above technical solution, the guide slider moves synchronously inside the guide groove, thereby making the movement of components such as the mounting bracket and connecting block more stable.
[0016] Preferably, one end of the connecting block is connected to the inner wall of one end of the mounting frame, and the outer wall of one end of the mounting frame is symmetrically hinged with a transmission arm via a rotating shaft.
[0017] By adopting the above technical solution, the transmission arm moves left and right in a cyclic manner, and then the transmission arm pushes the connecting block and the mounting frame to move left and right synchronously.
[0018] Preferably, the other end of the transmission arm is hinged to the outer wall of one end of the rotating disk, the rotating disk is rotatably connected to the inner side wall of the connecting frame, and the inner bottom end of the connecting frame is connected to the outer side wall of the feeding chamber through a fixing plate.
[0019] By adopting the above technical solution, the rotating disk drives the transmission arm to move during the rotation process, so that the transmission arm can move left and right.
[0020] Preferably, the inner walls on both sides of the connecting frame are rotatably connected with first bevel gears, and the opposite ends of the first bevel gears are driven to one end of the corresponding rotating disk. A linkage column is installed between the first bevel gears, and a second bevel gear is meshed with the outer wall of the bottom end of the first bevel gear. The bottom end of the second bevel gear is driven to the output end of the second motor.
[0021] By adopting the above technical solution, the first bevel gear and the linkage column cooperate with the second bevel gear to form a synchronous rotation structure, which drives the rotating disk to rotate synchronously.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. The shredding blades circulate and move left and right inside the feeding chamber to effectively shred the sludge and agricultural waste. This method allows the shredding blades to effectively shred the solid matter of the sludge and agricultural waste during feeding, which helps to improve the mixing uniformity and heat distribution, reducing the possibility of the middle part not being heated to the specified temperature. This avoids the problem of unreliable composition of the mixed mixture, and improves processing efficiency and effect.
[0024] 2. The mixture of sludge and agricultural waste and combustion accelerator at the bottom of the sludge-agricultural waste co-processing tank is turned upwards by the auger blades. The mixing plate rotates continuously, working in conjunction with the auger blades to complete the mixing operation. At the same time, the movement of the mixing plate drives the silicone scraper to scrape off the adhering substances on the inner side wall of the sludge-agricultural waste co-processing tank, reducing the occurrence of insufficient mixing and resource waste. Compared with traditional mixing methods, this method has a better mixing effect and is more thorough, effectively avoiding the problem of poor mixing effect of combustion accelerator.

[0033] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0034] This application discloses a co-processing device for sludge agricultural waste.
[0035] Reference Figure 1 and Figure 2 A sludge-agricultural waste co-treatment device includes a sludge-agricultural waste co-treatment tank 1. Electric heating tubes 2 are fixedly connected to the inside and bottom of the tank body of the sludge-agricultural waste co-treatment tank 1. The electric heating tubes 2 are arranged in a spiral structure. One end of the electric heating tube 2 is connected to the output flange of an electric heater 3, and the input end of the electric heater 3 is connected to the flange of the other end of the electric heating tube 2. The electric heater 3 is an electromagnetic induction heating structure. A discharge solenoid valve for discharging the mixture is provided at the bottom of the sludge-agricultural waste co-treatment tank 1. A base 25 is fixedly connected to the bottom of the sludge-agricultural waste co-treatment tank 1.
[0036] During use, the electric heater 3 is used to heat the sludge agricultural waste and the combustion aid according to the appropriate temperature of the mixture. This causes the heating liquid inside the electric heating tube 2 to flow, so that the temperature can continuously heat the sludge agricultural waste and the combustion aid inside the sludge agricultural waste co-processing tank 1. After the mixture is heated, the feeding operation is completed by controlling the feeding solenoid valve.
[0037] Reference Figure 1 and Figure 3The top flange of the sludge agricultural waste co-processing tank 1 is fixedly connected to the sludge agricultural waste co-processing tank cover 4, and the top of the sludge agricultural waste co-processing tank cover 4 is fixedly connected to the top of the sludge agricultural waste co-processing tank cover 4. The output end of the first motor 5 passes through the top of the sludge agricultural waste co-processing tank cover 4 and is fixedly connected to the top of the transmission column 6. The outer wall of the transmission column 6 is fixedly connected to the auger plate 7. Both sides of the auger plate 7 are provided with the mounting frame 8 fixedly connected to the outer wall of the transmission column 6. The interior of the mounting frame 8 is fixedly connected to the mixing plate 9, and the interior of the mixing plate 9 is provided with several through holes. The end of the mounting frame 8 away from the transmission column 6 is fixedly connected to the silicone scraper 10, and one end of the silicone scraper 10 abuts against the inner wall of the sludge agricultural waste co-processing tank 1.
[0038] When mixing sludge agricultural waste with combustion aid, the first motor 5 outputs power at a constant speed, driving the transmission column 6 to rotate synchronously. This causes the auger plate 7, which is fixedly connected to the outer wall of the transmission column 6, to rotate. The auger plate 7 then moves the mixture of sludge agricultural waste and combustion aid at the bottom of the sludge agricultural waste co-processing tank 1 upwards. The mixing plate 9 also rotates continuously, working in conjunction with the auger plate 7 to complete the mixing operation. During the movement of the mixing plate 9, the silicone scraper 10 scrapes off the deposits on the inner wall of the sludge agricultural waste co-processing tank 1, reducing incomplete mixing and resource waste. Compared with traditional mixing methods, this method has a better mixing effect and is more thorough, effectively avoiding the problem of poor mixing effect of combustion aid.
[0039] Reference Figure 1 , Figure 4 and Figure 5 One end of the sludge-agricultural waste co-processing tank cover 4 is fixedly connected to the feeding chamber 11, and one end of the feeding chamber 11 is connected to one end of the sludge-agricultural waste co-processing tank cover 4. One end of the feeding chamber 11 is provided with an insertion cavity, and a connecting block 15 is movably connected through the insertion cavity. One end of the connecting block 15 is fixedly connected with crushing blades 16 at equal intervals, and the crushing blades 16 are located inside the feeding chamber 11. The other end of the connecting block 15 is fixedly connected to the mounting frame 14, and the inner walls of both sides of the mounting frame 14 are fixedly connected with guide sliders 13 with a "convex" structure. The guide sliders 13 are slidably connected inside the guide grooves 12, and the inner sidewalls of the guide grooves 12 are set with a "convex" structure. The guide grooves 12 are symmetrically fixedly connected to the outer walls of both sides of the feeding chamber 11.
[0040] When feeding into the feeding chamber 11, the connecting block 15 moves left and right in a circular motion within the insertion chamber, thereby driving the crushing blade 16 to move left and right within the feeding chamber 11, effectively crushing the sludge agricultural waste. While the connecting block 15 moves left and right in a circular motion within the insertion chamber, the mounting frame 14, in conjunction with the guide sliders 13 on both inner walls, moves synchronously within the guide groove 12. This ensures that the connecting block 15, driving the crushing blade 16, remains stable and has a good cutting effect when moving left and right within the feeding chamber 11, thus avoiding the problem of the large volume of sludge agricultural waste in its solid state and poor mixing effect with the combustion aid.
[0041] Reference Figure 1 and Figure 5 One end of the mounting bracket 14 is hinged to one end of the transmission arm 17 via a rotating shaft, and the other end of the transmission arm 17 is hinged and fixed to one end of the outer wall of the rotating disk 18. The rotating disk 18 is rotatably connected to the outer walls of both sides of the connecting bracket 19. The inner bottom end of the connecting bracket 19 is fixedly connected to the outer wall of the feeding chamber 11 via a fixing plate 24. The inner sides of the connecting bracket 19 are rotatably connected to the first bevel gear 20. The opposite ends of the first bevel gear 20 are connected to the corresponding end of the rotating disk 18. A linkage column 21 is fixedly connected between the two first bevel gears 20. The bottom end of the first bevel gear 20 is meshed with the second bevel gear 22, and the bottom end of the second bevel gear 22 is fixedly connected to the output end of the second motor 23.
[0042] During use, the second motor 23 outputs the work, drives the second bevel gear 22 to rotate, and then drives the meshing first bevel gear 20 to rotate. A linkage column 21 is fixedly connected between the two first bevel gears 20, so that both first bevel gears 20 rotate. The first bevel gear 20 then drives the rotating disk 18 to rotate, and the rotating disk 18 drives one end of the transmission arm 17 to move, so that the transmission arm 17 moves left and right, and then drives the connecting block 15 to drive the crushing blade 16 to move left and right inside the feeding chamber 11.
[0043] The implementation principle of the sludge agricultural waste co-treatment device in this application embodiment is as follows:
[0044] First, the sludge agricultural waste is fed into the inside of the feeding chamber 11 and then transported to the inside of the sludge agricultural waste co-processing tank 1 through the feeding chamber 11. While the rotating disk 18 is rotating, it drives one end of the transmission arm 17 to move, causing the transmission arm 17 to move left and right, which in turn drives the connecting block 15 to drive the crushing blade 16 to move left and right inside the feeding chamber 11.
[0045] Secondly, by moving the crushing blade 16 left and right inside the feeding chamber 11, the sludge agricultural waste is effectively shredded and treated. The mounting frame 14 works in conjunction with the guide sliders 13 on both inner walls to move synchronously inside the guide groove 12, thereby ensuring that the connecting block 15 drives the crushing blade 16 to move left and right inside the feeding chamber 11 and remains stable.
[0046] Subsequently, based on the appropriate temperature for the sludge agricultural waste to be mixed with the combustion aid, the electric heater 3 is used for heating, which drives the flow of the heating liquid inside the electric heating tube 2, so that the temperature continuously heats the sludge agricultural waste and the combustion aid inside the sludge agricultural waste co-processing tank 1.
[0047] Finally, the first motor 5 outputs power at a constant speed, driving the transmission column 6 to rotate synchronously. This causes the auger plate 7, which is fixedly connected to the outer wall of the transmission column 6, to rotate. The auger plate 7 then drives the mixture of sludge agricultural waste and combustion aid at the bottom of the sludge agricultural waste co-processing tank 1 to turn upwards. The mixing plate 9 continues to rotate, working in conjunction with the auger plate 7 to complete the mixing operation. At the same time, during the movement of the mixing plate 9, the silicone scraper 10 scrapes off the deposits on the inner wall of the sludge agricultural waste co-processing tank 1. In this way, the sludge agricultural waste co-processing device is completed.
[0048] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
