Description

Technical Field

[0002] Reactors are multifunctional equipment widely used in industries such as chemical, pharmaceutical, food processing, coating and resin synthesis. They are mainly used to carry out chemical reactions under controlled conditions. They can provide a closed and controllable environment to allow the raw materials to undergo chemical changes under specific pressure and temperature to produce the desired products. Before feeding the materials into the reactor, people usually preheat the materials in order to increase the reaction rate and reduce the viscosity of the materials.

This invention sets a heat exchange component, so that solid materials can enter the interaction bin from the feed port, and at the same time, the steam in the steam chamber can be connected to the heat exchange component through the reflux pipe to provide heat in the interaction bin. Therefore, the heat exchange component rotates and contacts with the material for stirring, and also drives the spiral fins to rotate to transport the material through the first path, thereby achieving uniform preheating of the material.

DETAILED DESCRIPTION

[0038] The following will be combined with the 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.

[0039] Example 1, a reactor with external raw material heating function, such as Figure 1-Figure 8As shown, it includes a frame 1, a material pump 11, a reactor 12, a spiral rotating shaft 1201, a connecting pipe 13, a driving motor 14, an extrusion plate 15, a heating pipe 16, a crankshaft 17, a mobile frame 18, a mounting plate frame 19 and a protective shell 110. The material pump 11 is fixedly connected to the right side of the frame 1, and the reactor 12 is fixedly connected to the top of the frame 1. The reactor 12 and the material pump 11 are connected through a pipeline. The spiral rotating shaft 1201 is rotatably connected inside the reactor 12. The connecting pipe 13 is threadedly connected to the right side of the material pump 11. The middle part of the connecting pipe 13 is fixedly connected and connected to the mounting plate 19. A mounting plate frame 19 is fixedly connected to a protective shell 110 in the middle part of the mounting plate frame 19, a driving motor 14 is fixedly connected to the upper side of the inner part of the protective shell 110, a crankshaft 17 is rotatably connected to the upper side of the inner part of the protective shell 110, an output end of the driving motor 14 is fixedly connected to the crankshaft 17 through a coupling, a moving frame 18 is slidably connected to the upper side of the inner part of the protective shell 110, the moving frame 18 is movably connected to the crankshaft 17, extrusion plates 15 are fixedly connected to the left and right sides of the lower part of the moving frame 18, the extrusion plate 15 is slidably connected to the mounting plate frame 19, and heating tubes 16 are fixedly connected to the left and right sides of the mounting plate frame 19.

[0040] like Figure 7 and Figure 8 As shown, the two extrusion plates 15 are provided with evenly distributed oblique stripe grooves on the sides away from each other, so as to make the material flow and disperse evenly.

[0041] When workers need to use the reactor 12 to pyrolyze materials such as oil sludge to separate water, oil and mud in the oil sludge, the materials can be input into the reactor 12 through the material pump 11 and pyrolyzed. During this period, the spiral rotating shaft 1201 will continuously rotate and stir the materials. If it is necessary to preheat the materials to increase the pyrolysis rate, the rear end of the connecting pipe 13 can be connected to the material pump 11 by means of a thread, and then the front end of the connecting pipe 13 can be connected to the external feeding device. After that, the material pump 11 can be started to allow the materials to pass through the connecting pipe 13 and the mounting plate frame 19 and finally enter the reactor 12. When the materials pass through the mounting plate frame 19, the heating pipe 16 can be started to preheat the materials. 9 has two extrusion plates 15, so the material can only pass through the two narrow channels on the left and right formed by the mounting plate frame 19 and the two extrusion plates 15, so that the sludge and other materials can be evenly spread, thereby increasing the heating area of ​​the material to improve the heating rate. At this time, the drive motor 14 can also be started to drive the crankshaft 17 to rotate continuously, and the protruding part of the crankshaft 17 is squeezed with the moving frame 18, so that when the crankshaft 17 rotates continuously, it will drive the moving frame 18 and the left and right extrusion plates 15 to move up and down continuously, thereby improving the fluidity of the material in the up and down directions, so that the material can be heated more evenly, thereby improving the preheating effect of the device, and the heating tube 16 and the drive motor 14 can be turned off when preheating is not required.

[0042] Embodiment 2, on the basis of embodiment 1, as Fig. 9 and Fig.10 As shown, a melting mechanism is also included, which is arranged in the protective shell 110. The melting mechanism includes an air pump 2, an air pipe 22, an air delivery pipe 23, a hollow heat conducting plate 24, a return pipe 25, a rotating blade 26, a rotating block 27 and a mounting cylinder 28. The air pump 2 is fixedly connected to the upper side of the inner part of the protective shell 110, and the mounting cylinder 28 is fixedly connected to the upper part of the rear side of the protective shell 110. The air pipe 22 is fixedly connected to the upper side of the inner part of the protective shell 110. The air pipe 22 is connected to the air pump 2, and the air pipe 22 is Y-shaped. One end of the connecting tube 13 is fixedly connected to and communicated with the bottom of the mounting tube 28, and the other two ends of the air guide tube 22 are respectively fixedly connected to and communicated with the left and right sides of the middle of the protective shell 110. A rotating block 27 is rotatably connected inside the mounting tube 28, and a rotating blade 26 is fixedly connected to the lower part of the rotating block 27. Hollow heat conducting plates 24 are fixedly connected to the front and rear sides of the connecting tube 13. The left and right air delivery pipes 23 are fixedly connected and communicated between the hollow heat conducting plate 24 and the protective shell 110, and a return pipe 25 is fixedly connected and communicated between the hollow heat conducting plate 24 and the upper part of the mounting tube 28.

[0043] like Fig. 9 and Fig.10 As shown, an expansion gas block 21 is also included, and the rear portion of the air guide pipe 22 is fixedly connected to and communicated with the expansion gas block 21 .

[0044] When the material is preheated by the heating tube 16, the air pump 2 can also be started. Since the heating tube 16 is located on the left and right sides of the space formed by the mounting plate frame 19 and the protective shell 110, there is hot air with a relatively high temperature in this space, and the air pump 2 can make the hot air in this space enter the hollow heat-conducting plates 24 on the front and rear sides through the air delivery pipe 23, and heat the front and rear parts of the connecting pipe 13 to prevent the material from gradually solidifying and agglomerating during transportation, thereby affecting the flow rate of the material and even causing the connecting pipe 13 to be blocked by the material, thereby ensuring the fluidity and transportation rate of the material, and the air flowing into the hollow heat-conducting plate 24 will also flow into the mounting tube 28 through the return pipe 25, and then flow back to the space formed by the mounting plate frame 19 and the protective shell 110 through the expansion gas block 21 and the air guide pipe 22 and other components. , thereby forming a circulating flow of gas, and when the air flows through the mounting tube 28, it will also drive the rotating blades 26 to rotate continuously, thereby driving the rotating block 27 to rotate continuously, and the rotation of the rotating block 27 will block the return pipes 25 on the front and rear sides in turn, so that the gas in the hollow heat conducting plates 24 on the front and rear sides can intermittently reflux, so that the hot air can stay in the hollow heat conducting plates 24 for a longer period of time, thereby improving the heating effect of the hollow heat conducting plates 24. When one of the return pipes 25 is blocked by the rotating block 27, it is difficult for the air pump 2 to inhale a sufficient amount of gas only through the other return pipe 25, so the air pump 2 will inhale the gas in the expansion gas block 21, thereby causing the expansion gas block 21 to deform and shrink, and when both return pipes 25 are not blocked, the expansion gas block 21 will deform and return to its original state under the action of its own elasticity.

[0045] like Fig.11 and Fig.12 As shown, a scraper mechanism is also included, which is arranged on the mounting plate frame 19. The scraper mechanism includes a guide frame 3, a limiting rod 31, a first connecting frame 32 and a scraper frame 33. The four first connecting frames 32 are respectively slidably connected to the front and rear sides of the left and right parts of the mounting plate frame 19. The scraper frame 33 is fixedly connected between the front and rear first connecting frames 32. The scraper frame 33 is slidably connected to the mounting plate frame 19. The guide frame 3 is fixedly connected between the tops of the front and rear first connecting frames 32. The limiting rods 31 are fixedly connected to the left and right sides of the movable frame 18. The limiting rods 31 are slidably connected to the adjacent guide frames 3.

[0046] like Fig.11 and Fig.12 As shown, the guide frame 3 is provided with an oblique sliding groove for the adjacent limiting rod 31 to slide.

[0047] When the movable frame 18 moves up and down and back and forth under the action of the crankshaft 17, the left and right limit rods 31 will also move up and down and back and forth with the movable frame 18, thereby driving the guide frame 3, the first connecting frame 32 and the scraper frame 33 on the left and right sides to move back and forth, so that the material adhering to the inner wall of the mounting plate frame 19 can be scraped off, avoiding the channel formed by the mounting plate frame 19 and the extrusion plate 15 being gradually blocked by the material, thereby ensuring the fluidity and conveying rate of the material, and the scraper frame 33 moving back and forth can also stir the material in the channel, so that the material is heated more evenly, thereby improving the preheating effect of the device.

[0048] like Fig.13 and Fig.14 As shown, a crushing mechanism is also included, which is arranged on the connecting tube 13. The crushing mechanism includes a rotating shaft 4, a cutter 41, a protective shell 42 and a double-axis motor 43. The protective shell 42 is fixedly connected to the front side of the connecting tube 13, and the double-axis motor 43 is fixedly connected to the inside of the protective shell 42. The output ends on both sides of the double-axis motor 43 are fixedly connected to the rotating shaft 4 through couplings, and the outside of the rotating shaft 4 is fixedly connected to a spirally distributed cutter 41.

[0049] When the material passes through the connecting pipe 13, the dual-axis motor 43 can also be started to drive the rotating shafts 4 on the left and right sides to rotate, thereby driving the cutter 41 on the rotating shaft 4 to rotate continuously, so that the material agglomerated in the connecting pipe 13 can be broken up to prevent the agglomeration from affecting the material transportation or even clogging the pipeline. The particle size of the agglomerated material can also be reduced to facilitate the subsequent melting of the agglomerates and preheating of the materials. Since the cutter 41 on the rotating shaft 4 is spirally distributed, the cutter 41 will not cause too much obstruction to the transportation and flow of the material, and can also cut and break the flowing material multiple times, thereby improving the crushing effect of the cutter 41, wherein the protective shell 42 is used to wrap and protect the dual-axis motor 43.

[0050] like Fig.15 and Fig.16 As shown, it also includes a feeding mechanism, which is arranged in the protective shell 110. The feeding mechanism includes a storage box 5, a second connecting frame 51, a piston rod 52 and a guide tube 53. The storage box 5 is fixedly connected to the left side of the protective shell 110. The front and rear sides of the upper part of the storage box 5 are slidably connected with the piston rod 52. The second connecting frame 51 is fixedly connected between the tops of the front and rear piston rods 52. The second connecting frame 51 is fixedly connected to the adjacent limit rod 31. The rear side of the storage box 5 is fixedly connected to the top of the rear side of the mounting plate frame 19 and is connected with the guide tube 53.

[0051] like Fig.15 and Fig.16 As shown, a one-way valve is fixedly connected to the top of the storage box 5 to maintain the internal air pressure of the storage box 5 stable.

[0052] like Fig.15 and Fig.16As shown, a one-way valve is fixedly connected to the front of the flow guide pipe 53 to prevent the additive from flowing back.

[0053] Before starting the material pump 11, the worker can first add additives such as inorganic acids or alkaline compounds into the storage box 5. When the limit rod 31 on the left moves back and forth with the moving frame 18, the limit rod 31 will first drive the second connecting frame 51 and the piston rod 52 to move downward and inject the additives in the storage box 5 into the material in the mounting plate frame 19 through the guide pipe 53. Then the limit rod 31 will drive the second connecting frame 51 and the piston rod 52 to move upward and reset. At this time, due to the one-way valve on the guide pipe 53, the additive will not flow back through the guide pipe 53, so When the piston rod 52 moves upward and resets, it will inhale external air through the one-way valve on the storage box 5, thereby maintaining the air pressure in the storage box 5 stable. In this way, additives can be intermittently added to the material through a cycle. During the upward and downward movement of the limit rod 31, the second connecting frame 51 and the piston rod 52, the material will continue to flow through the mounting plate frame 19 at a uniform speed. Therefore, the guide tube 53 can evenly add additives such as inorganic acids or alkaline compounds to materials such as oil sludge, help destroy the emulsified layer in the oil sludge, thereby promoting oil-water separation, thereby improving the oil-water separation effect of the device.

[0054] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
