Description

Technical Field

[0001] The present invention relates to the technical field of chemical engineering, and specifically relates to a multifunctional reactor for biofuel. Background Art

[0002] The market of bio-alcohol fuel and alcohol-based fuel is booming. After nearly 30 years of development, emulsified fuel has gradually matured at home and abroad. Emulsified fuel is made by adding an appropriate amount of water to fuel oil (heavy oil, diesel, gasoline, residue oil), then adding additives (surfactants), and applying mechanical action (vibration, stirring, mixing) to emulsify the oil into water-in-oil particles (0.3nm), namely "hydrogen oil".

[0003] A multifunctional reactor for biofuel disclosed in a Chinese patent with the publication number of "CN202063888U" is characterized in that: it includes a mixing container and a pump group. Each pump in the pump group sucks fuel oil, water and emulsifier respectively, and each pump pumps fuel oil, water and emulsifier into the mixing container along the tangential direction of the container, and forms a vortex in the container for mixing.

[0004] When the above patent is in use, various liquids flow into the container along the tangent to form a vortex for mixing, but the mixing uniformity is insufficient, which leads to the reduction of the overall performance of the emulsified fuel. Therefore, a multifunctional reactor for biofuel is proposed to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a multifunctional reactor for biofuel aiming at the deficiencies in the above-mentioned prior art.

[0006] To solve the above technical problem, the technical solution adopted by the present invention is: a multifunctional reactor for biofuel, including a reaction tank. A feed port is arranged at the top of the reaction tank, a discharge pipe is arranged at the bottom of the reaction tank, a hydraulic motor is fixedly connected to the top of the reaction tank, and a radial stirring mechanism is arranged inside the reaction tank;

[0007] The radial stirring mechanism includes a transmission shaft, two threaded sleeves, two lead screws, a cross bar, a first stirring rod, a curved slide rail, a first slider, a first vertical rod, and a second vertical rod;

[0008] The upper and lower ends of the transmission shaft are rotatably connected to the inner walls of the upper and lower sides of the reaction tank through bearings respectively. The top end of the transmission shaft is fixedly connected to the bottom output end of the hydraulic motor. The threaded sleeves are fixedly connected to the middle of the transmission shaft. The lead screws are threadedly penetrated through the threaded sleeves. The cross bar is fixedly connected to both ends of the lead screws. The first stirring rod is fixedly connected to the other end of the cross bar away from the lead screws. The upper and lower ends of the second vertical rod are rotatably connected to the left two cross bars through bearings respectively. When the bottom cross bar moves left and right, the top cross bar is driven to move left and right through the second vertical rod;

[0009] The curved slide rail is provided on the inner wall of the bottom of the reaction tank. The first slider is slidably connected inside the curved slide rail. The bottom end of the first vertical rod is fixedly connected to the top of the first slider. The top end of the first vertical rod is rotatably connected to the right-bottom cross bar through a bearing.

[0010] Preferably, an axial stirring mechanism is provided inside the reaction tank. The axial stirring mechanism includes two sliding sleeves. The two sliding sleeves are sleeved outside the transmission shaft. A straight sliding groove is provided on the inner wall of the sliding sleeve. Second sliders are fixedly connected to the left and right sides of the transmission shaft. The second sliders are slidably connected inside the straight sliding groove. Second stirring rods are fixedly connected to the front and back sides of the sliding sleeve. By providing the straight sliding groove and the second slider, the up and down movement of the sliding sleeve and the second stirring rod is limited.

[0011] Preferably, a fixing block is fixedly connected to the middle of the second vertical rod. Two movable rods are hinged to the right side of the fixing block. The other ends of the two movable rods away from the second vertical rod are respectively hinged to the two sliding sleeves. When the second vertical rod moves, the sliding sleeves and the second stirring rods are driven to move up and down through the movable rods.

[0012] Preferably, first sleeves are fixedly connected to the opposite sides of the two sliding sleeves. The opposite sides of the two first sleeves are fixedly connected with a second sleeve through two connecting rods. The two connecting rods are respectively arranged on the front and back sides of the transmission shaft. The first sleeve and the second sleeve are sleeved outside the transmission shaft. Scrapers are fixedly connected to the inner walls of the first sleeve and the second sleeve. The fuel oil attached to the surface of the transmission shaft is scraped off by the up and down movement of the scraper.

[0013] Preferably, a tank bottom stirring mechanism is provided inside the reaction tank. The tank bottom stirring mechanism includes two first movable plates. The right first movable plate is fixedly connected to the first vertical rod. A horizontal shaft is rotatably connected between the two first movable plates through a bearing. When the first vertical rod moves towards the transmission shaft, the first movable plate is driven to move. When the first movable plate moves, a thrust is generated to turn up the materials at the bottom of the reaction tank, reducing the stirring dead angle.

[0014] Preferably, rollers are fixedly connected to the horizontal shaft. The rollers are slidably connected to the inner wall of the bottom of the reaction tank. Brush hairs are fixedly connected to the horizontal shaft. The brush hairs are in contact with the inner wall of the bottom of the reaction tank. The emulsifier attached to the inner wall of the bottom of the reaction tank is cleaned by the brush hairs, and the emulsifier is turned up in cooperation with the first movable plate.

[0015] Preferably, telescopic rods are fixedly connected to the opposite sides of the two first movable plates. The other ends of the telescopic rods away from the first movable plates are fixedly connected to a second movable plate.

[0016] Preferably, an elastic liquid sac is arranged between the second movable plate and the first movable plate. The left and right ends of the elastic liquid sac are fixedly connected to the first movable plate and the second movable plate respectively. One end of the elastic liquid sac is provided with a nozzle. One end of the nozzle penetrates through the first movable plate. When the first movable plate moves towards the transmission shaft, it drives the telescopic rod and the second movable plate to move towards the transmission shaft. When the second movable plate contacts the transmission shaft, it moves towards the first movable plate and squeezes the elastic liquid sac. After being squeezed, the liquid inside the elastic liquid sac is ejected, and the emulsifier precipitated on the inner wall of the bottom of the reaction tank is lifted by the ejected liquid, further improving the mixing uniformity of the materials at the bottom of the reaction tank.

[0017] Adopting the above technical solutions, the present invention can bring the following beneficial effects:

[0018] 1. By setting the radial stirring mechanism, the invention drives the threaded sleeve to rotate through the transmission shaft, making the first stirring rod rotate around the transmission shaft and move left and right, improving the stirring uniformity of fuel oil, water and emulsifier. At the same time, the self-rotation of the lead screw drives the cross bar and the first stirring rod to rotate, and the multi-directional movement further improves the stirring uniformity of fuel oil, water and emulsifier, enabling the materials to be fully mixed in the reactor, laying a good foundation for subsequent reactions, and ultimately improving the overall performance of the emulsified fuel.

[0019] 2. By setting the axial stirring mechanism, the invention drives the sliding sleeve and the second stirring rod to move up and down through the movement of the second vertical rod driving the movable rod, and at the same time the rotation of the transmission shaft drives them to rotate. This compound movement improves the stirring effect of the second stirring rod. In addition, the sliding sleeve drives the scraper to move up and down, which can scrape off the fuel oil attached to the surface of the transmission shaft, avoiding the influence of fuel oil attachment on stirring and reaction, further enhancing the overall stirring effect, and making the material mixing more sufficient.

[0020] 3. By setting the tank bottom stirring mechanism, the invention drives the first movable plate to move through the first vertical rod, which can turn up the materials at the bottom of the reaction tank, reduce the stirring dead angle, and enable the bottom materials to also participate in sufficient mixing. The bristles on the cross shaft clean the emulsifier attached to the tank bottom, cooperate with the first movable plate to turn up the emulsifier, increasing the contact opportunity between the emulsifier and other materials. Moreover, the movement of the first movable plate squeezes the elastic liquid sac, and the ejected liquid lifts the emulsifier precipitated at the tank bottom, further improving the mixing uniformity of the materials at the tank bottom and ensuring the consistency of material mixing throughout the reactor.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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 efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-8 , one embodiment of the present invention is: a multifunctional reactor for biofuel, including a reaction tank 1, a feed inlet 2 is arranged at the top of the reaction tank 1, a discharge pipe 3 is arranged at the bottom of the reaction tank 1, a hydraulic motor 4 is fixedly connected to the top of the reaction tank 1, and a radial stirring mechanism 5 is arranged inside the reaction tank 1;

[0032] The radial stirring mechanism 5 includes a transmission shaft 501, two threaded sleeves 502, two lead screws 503, a cross bar 504, a first stirring rod 505, a curved slide rail 506, a first slider 507, a first vertical rod 508, and a second vertical rod 509;

[0033] The upper and lower ends of the transmission shaft 501 are respectively rotationally connected to the inner walls of the upper and lower sides of the reaction tank 1 through bearings. The top end of the transmission shaft 501 is fixedly connected to the bottom output end of the hydraulic motor 4. The threaded sleeve 502 is fixedly connected to the middle of the transmission shaft 501. The lead screw 503 is threadedly penetrated through the threaded sleeve 502. The cross bar 504 is fixedly connected to both ends of the lead screw 503. The first stirring rod 505 is fixedly connected to the other end of the cross bar 504 away from the lead screw 503. The upper and lower ends of the second vertical rod 509 are respectively rotationally connected to the two left cross bars 504 through bearings. When the bottom cross bar 504 moves left and right, it drives the top cross bar 504 to move left and right through the second vertical rod 509;

[0034] The curved slide rail 506 is opened on the inner wall of the bottom of the reaction tank 1. The first slider 507 is slidably connected to the inside of the curved slide rail 506. The bottom end of the first vertical rod 508 is fixedly connected to the top of the first slider 507. The top end of the first vertical rod 508 is rotationally connected to the lower right cross bar 504 through a bearing.

[0035] Working principle: First, fuel oil, water, and emulsifier are put into the reaction tank 1 from the feed port 2. Then, the hydraulic motor 4 is started to drive the transmission shaft 501 to rotate. The rotation of the transmission shaft 501 drives the threaded sleeve 502 to rotate. The rotation of the threaded sleeve 502 drives the first slider 507 to rotate through the first vertical rod 508. During the rotation of the first slider 507, it will repeatedly approach or move away from the transmission shaft 501 under the action of the curved slide rail 506, and drive the cross bar 504 and the lead screw 503 to move through the first vertical rod 508, and drive the first stirring rods 505 on both sides to move left and right when rotating around the transmission shaft 501, improving the stirring uniformity. During the movement of the lead screw 503 in the threaded sleeve 502, it rotates itself and drives the cross bar 504 and the first stirring rod 505 to rotate, thereby further improving the stirring uniformity.

[0036] Please refer to Figure 1-8 In another embodiment of the present invention on the basis of the above embodiment, an axial stirring mechanism 6 is provided inside the reaction tank 1. The axial stirring mechanism 6 includes two sliding sleeves 601. The two sliding sleeves 601 are sleeved outside the transmission shaft 501. A straight chute 602 is opened on the inner wall of the sliding sleeve 601. Second sliders 603 are fixedly connected to the left and right sides of the transmission shaft 501. The second sliders 603 are slidably connected to the inside of the straight chute 602. Second stirring rods 604 are fixedly connected to the front and rear sides of the sliding sleeve 601. The up and down movement of the sliding sleeve 601 and the second stirring rod 604 is limited by providing the straight chute 602 and the second sliders 603.

[0037] A fixing block 605 is fixedly connected to the middle of the second vertical rod 509. Two movable rods 606 are hinged to the right side of the fixing block 605. The other ends of the two movable rods 606 away from the second vertical rod 509 are respectively hinged to two sliding sleeves 601. When the second vertical rod 509 moves, the sliding sleeves 601 and the second stirring rod 604 are driven to move up and down through the movable rods 606.

[0038] On the opposite sides of the two sliding sleeves 601, a first sleeve 607 is fixedly connected. On the opposite sides of the two first sleeves 607, a second sleeve 609 is fixedly connected through two connecting rods 608. The two connecting rods 608 are respectively arranged on the front and back sides of the transmission shaft 501. The first sleeve 607 and the second sleeve 609 are sleeved on the outside of the transmission shaft 501. A scraping plate is fixedly connected to the inner walls of the first sleeve 607 and the second sleeve 609. The fuel oil adhering to the surface of the transmission shaft 501 is scraped off by the up and down movement of the scraping plate.

[0039] Working principle: When the second vertical rod 509 moves towards the transmission shaft 501, the sliding sleeves 601 and the second stirring rod 604 are driven to move up and down through the movable rods 606. When the transmission shaft 501 rotates, the sliding sleeves 601 and the second stirring rod 604 are driven to rotate through the straight sliding grooves 602 and the second sliders 603, thereby improving the stirring effect of the second stirring rod 604. The up and down movement of the sliding sleeve 601 drives the first sleeve 607, the connecting rods 608 and the second sleeve 609 to move up and down, and the fuel oil adhering to the surface of the transmission shaft 501 is scraped off by the up and down movement of the scraping plate, thereby further improving the stirring effect on the fuel oil, water and emulsifier.

[0040] Please refer to Figure 1-8 , on the basis of the above embodiment, in another embodiment of the present invention, a tank bottom stirring mechanism 7 is arranged inside the reaction tank 1. The tank bottom stirring mechanism 7 includes two first movable plates 701. The right first movable plate 701 is fixedly connected to the first vertical rod 508. A horizontal shaft 702 is rotatably connected between the two first movable plates 701 through a bearing. When the first vertical rod 508 moves towards the transmission shaft 501, the first movable plate 701 is driven to move. When the first movable plate 701 moves, a thrust is generated to turn up the materials at the bottom of the reaction tank 1, reducing the stirring dead angle.

[0041] A roller 703 is fixedly connected to the horizontal shaft 702. The roller 703 is slidably connected to the inner wall of the bottom of the reaction tank 1. A brush 704 is fixedly connected to the horizontal shaft 702. The brush 704 contacts the inner wall of the bottom of the reaction tank 1. The emulsifier adhering to the inner wall of the bottom of the reaction tank 1 is cleaned by the brush 704, and the emulsifier is turned up in cooperation with the first movable plate 701.

[0042] On the opposite sides of the two first movable plates 701, telescopic rods 705 are fixedly connected, and at the other end of the telescopic rod 705 away from the first movable plate 701, a second movable plate 706 is fixedly connected.

[0043] An elastic liquid sac 707 is arranged between the second movable plate 706 and the first movable plate 701. The left and right ends of the elastic liquid sac 707 are respectively fixedly connected to the first movable plate 701 and the second movable plate 706. One end of the elastic liquid sac 707 is provided with a nozzle 708. One end of the nozzle 708 penetrates through the first movable plate 701. When the first movable plate 701 moves towards the transmission shaft 501, it drives the telescopic rod 705 and the second movable plate 706 to move towards the transmission shaft 501. When the second movable plate 706 contacts the transmission shaft 501, it moves towards the first movable plate 701 and squeezes the elastic liquid sac 707. After being squeezed, the liquid inside the elastic liquid sac 707 is ejected, and the emulsifier precipitated on the inner wall of the bottom of the reaction tank 1 is lifted by the ejected liquid, further improving the mixing uniformity of the materials at the bottom of the reaction tank 1.

[0044] Working principle: When the first vertical rod 508 moves towards the transmission shaft 501, it drives the first movable plate 701 to move. When the first movable plate 701 moves, it generates a thrust to turn up the materials at the bottom of the reaction tank 1, reducing the stirring dead angle. While the first vertical rod 508 rotates around the transmission shaft 501, it drives the first movable plate 701 to rotate around the transmission shaft 501. When the first movable plate 701 rotates around the transmission shaft 501, it drives the cross shaft 702 and the roller 703 to rotate around the transmission shaft 501. Since the roller 703 contacts the inner wall of the bottom of the reaction tank 1, it rotates around its own axis while rotating around the transmission shaft 501, and drives the cross shaft 702 and the brush bristles 704 to rotate around their own axes, cleaning the emulsifier attached to the inner wall of the bottom of the reaction tank 1, and cooperating with the first movable plate 701 to turn up the emulsifier. When the first movable plate 701 moves towards the transmission shaft 501, it drives the telescopic rod 705 and the second movable plate 706 to move towards the transmission shaft 501. When the second movable plate 706 contacts the transmission shaft 501, it moves towards the first movable plate 701 and squeezes the elastic liquid sac 707. After being squeezed, the liquid inside the elastic liquid sac 707 is ejected, and the emulsifier precipitated on the inner wall of the bottom of the reaction tank 1 is lifted by the ejected liquid, further improving the mixing uniformity of the materials at the bottom of the reaction tank 1.

[0045] The present invention provides a multifunctional reactor for biofuel. There are many methods and ways to specifically implement this technical solution. The above description is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be realized by existing technologies.
