[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-5 This utility model provides a technical solution: a marine biofuel production device, including a vessel body 1 and a cover body 2 connected to the upper end of the vessel body 1. A circulation assembly is provided at the lower end of the vessel body 1, including a first circulation pump 4 and a second circulation pump 5. The first circulation pump 4 and the second circulation pump 5 are symmetrically distributed. The output end of the second circulation pump 5 is connected to the upper side wall of the vessel body 1. A spray assembly is provided on the upper side wall of the vessel body 1, and the spray assembly is connected to the output pipe of the second circulation pump 5. The output end of the first circulation pump 4 extends into the vessel body 1, and the output end of the first circulation pump 4 is connected to an inner pipe 12. The inner end of the inner pipe 12 is connected to a communicating nozzle 11. There are multiple nozzles 11, and they are arranged at different pitch angles. The vessel body 1 and the lid 2 are equipped with raw material inlets and multiple auxiliary material inlets. This is existing known technology and will not be described in detail here. After all the materials inside the vessel body 1 are put in, the materials inside the vessel body 1 are circulated and mixed by the circulation component. Specifically, the first circulation pump 4 and the second circulation pump 5 are used to fully mix the materials inside the vessel body 1 from the bottom and the middle and upper parts of the vessel body 1. The upper part of the vessel body 1 is sucked and mixed by the spray component. The second circulation pump 5 circulates the materials at the bottom to the top of the vessel body 1 and sprays them into the vessel body 1 through the spray component. At the same time, the first circulation pump 4 sprays the materials inside through the nozzles 11 at the bottom. The different angles of the nozzles 11 can spray the materials out without dead angles, thereby achieving a better mixing effect.
[0022] like Figure 2 As shown, the spray assembly includes a spray pipe 7, which is fixed to both sides of the upper end of the vessel body 1, with the spray end located inside the vessel body 1. The outer wall of the vessel body 1 is fixedly connected to a first discharge port 8, a second discharge port 9, and a third discharge port 10, which are equidistantly distributed from top to bottom. The third discharge port 10 is connected to a second circulating pump 5. The spray pipe 7 extends into the interior of the vessel body 1, spraying the material down from the spray pipe 7 for mixing. At the same time, the material circulates through the first discharge port 8, the second discharge port 9, and the third discharge port 10, and then circulates again through the second circulating pump 5 before passing through the spray pipe 7 for further mixing. The material also achieves a good mixing effect in the pump chamber of the second circulating pump 5.
[0023] like Figure 5As shown, the nozzles 11 are designed with angles of 0°, 15°, 30° and 45°, and are distributed on the inner tube 12 in a periodic manner. The nozzles 11 are designed with a periodic design of 0°, 15°, 30° and 45°, so that the material can be sprayed upwards without dead angles inside the vessel 1, thereby achieving a better mixing effect.
[0024] like Figure 4 As shown, a second manhole 14 is fixedly connected to the side wall of the vessel body 1, and a first manhole 13 is fixedly connected to the upper end of the cover body 2. The interior of the vessel body 1 can be maintained and inspected from the side and top through the first manhole 13 and the second manhole 14, respectively, which facilitates operation and maintenance and improves maintenance efficiency.
[0025] like Figure 1 As shown, a protective frame 3 is fixedly connected to the upper edge of the cover 2; the protective frame 3 can prevent personnel from being in danger during maintenance and repair, and also facilitates personnel to get on and off.
[0026] like Figure 2 As shown, the lower end of the spray pipe 7 is provided with three rows of spray holes; within a radial range of 60° and an axial range of 1000mm, there are three rows of holes with a diameter of 10mm, 42 holes in each row, for a total of 126 holes. This makes the spraying effect better and the mixing effect of the materials better.
[0027] like Figure 2 As shown, a tube heat exchanger 6 is fixedly connected between the second circulation pump 5 and the spray pipe 7; adding a tube heat exchanger 6 to the pipeline can be used to control the temperature of the material, and to heat up and cool down.
