Description

Technical Field

[0001] The utility model relates to the technical field of curdlan processing, in particular to a curdlan mixing device. Background Art

[0002] Curdlan is a polysaccharide produced by specific microorganisms through a fermentation process. During the production of curdlan, the fermentation broth contains a large amount of curdlan and other impurities. To separate the curdlan from the fermentation broth, an appropriate amount of alcohol is usually added.

[0003] Under the influence of alcohol, the solubility of curdlan molecules decreases, causing them to gradually precipitate from the fermentation broth. This precipitation process is caused by changes in the interaction between the curdlan molecules and the alcohol molecules. When the alcohol concentration reaches a certain level, the interaction between the curdlan molecules strengthens, forming larger aggregates that eventually precipitate.

[0004] The Chinese utility model patent application number 202222947877.4 proposes a stirring device for curdlan processing. The main problem with this patent is that the structure of the stirring mechanism is complex. During the mixing process, a large amount of curdlan solution adheres to the stirring mechanism and the threaded rod, which not only causes a large amount of curdlan waste but also makes it very difficult to clean up.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A curdlan mixing device comprises a mixing tank, wherein a plurality of bidirectional stirring flow components are sequentially arranged inside the mixing tank from top to bottom, the bidirectional stirring flow components are connected to a nitrogen source through an air inlet pipeline, a solution inlet and an alcohol inlet are provided at the top of the mixing tank, and a discharge port is provided at the bottom of the mixing tank.

A first air vent pipe and a second air vent pipe are provided in the tank wall of the mixing tank. All forward air outlet pipes are connected to the air outlet end of the forward air intake pipe through the first air vent pipe, and all reverse air outlet pipes are connected to the air outlet end of the reverse air outlet pipe through the second air vent pipe.

[0023] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 3 As shown together, a curd rubber mixing device includes a mixing tank 1. Several two-way stirring components 2 are arranged in sequence from top to bottom inside the mixing tank 1. The two-way stirring components 2 are connected to a nitrogen source 4 through an air inlet pipe 3. A solution inlet 5 and an alcohol inlet 6 are provided at the top of the mixing tank 1, and a discharge port 7 is provided at the bottom of the mixing tank 1.

[0025] In this embodiment, no complicated moving parts are provided inside the mixing tank 1 and the structure is simple, which simplifies the internal structure of the mixing tank 1 and facilitates subsequent cleaning, maintenance and operation of the mixing device.

[0026] In this embodiment, the curdlan solution is injected into the mixing tank 1 through the solution inlet 5 , and the alcohol is injected into the mixing tank 1 through the alcohol inlet 6 .

[0027] In this embodiment, the nitrogen source 4 is used to introduce pure high-pressure nitrogen into the bidirectional stirring component 2 .

[0028] In this embodiment, the bidirectional stirring assembly 2 is used to intermittently inject high-pressure nitrogen into the mixing tank 1 in opposite directions.

[0029] like Figure 1 As shown, the bidirectional stirring flow component 2 includes a forward air outlet pipe 21 and a reverse air outlet pipe 22 coaxially arranged above and below. The side wall of the forward air outlet pipe 21 is provided with a number of forward air outlets 23 arranged at equal intervals, and the side wall of the reverse air outlet pipe 22 is provided with a number of reverse air outlets 24 arranged at equal intervals. Both the forward air outlet pipe 21 and the reverse air outlet pipe 22 are connected to the air inlet pipe 3, and a reversing air intake mechanism 8 is installed on the air inlet pipe 3.

[0030] In this embodiment, only a plurality of forward air outlet pipes 21 and reverse air outlet pipes 22 are arranged at intervals inside the mixing tank 1, so there are very few parts for the curdlan solution to adhere to, thereby greatly reducing the adhesion of the curdlan solution inside the mixing tank and solving the problem of curdlan being easily adhered to by complex structures and causing waste.

[0031] Moreover, the curdlan solution adhering to the surfaces of the forward air outlet pipe 21 and the reverse air outlet pipe 22 can be cleaned by a simple flushing operation, which is very convenient.

[0032] In this embodiment, the optimal number of the forward air outlets 23 is three.

[0033] In this embodiment, the optimal number of the reverse air outlets 24 is three.

[0034] In this embodiment, the reversing air intake mechanism 8 is used to control the direction in which the high-pressure nitrogen gas enters the mixing tank 1 .

[0035] The forward air outlet 23 and the reverse air outlet 24 are both oblique openings, and the air outlet direction of the forward air outlet 23 is opposite to the air outlet direction of the reverse air outlet 24 .

[0036] In this embodiment, the gas outlet directions of the forward gas outlet 23 and the reverse gas outlet 24 are both arranged along the tangential direction of the inner wall of the mixing tank 1 .

[0037] In this embodiment, high-pressure nitrogen is injected into the curdlan solution in a tangential direction. The high-speed flow of nitrogen generates strong kinetic energy, which can be converted into shear force and impact force on the curdlan solution.

[0038] The tangentially injected high-pressure nitrogen produces a shearing effect in the curdlan solution, causing the curdlan solution to move relative to the horizontal direction, thereby increasing the contact area between the curdlan solution and the alcohol and improving the mixing efficiency.

[0039] At the same time, the impact force of high-pressure nitrogen on the curdlan will cause the curdlan solution to move in the vertical direction, further breaking the cohesion between the curdlan and making it mix more evenly with the alcohol.

[0040] Therefore, under the stirring of high-pressure nitrogen, the curdlan solution forms vortices and eddies, and the alcohol added thereto can be fully mixed with the curdlan.

[0041] like Figure 1-Figure 3 As shown in common, the air intake pipeline 3 includes an air intake manifold 31 connected to the air outlet end of the nitrogen source 4, the air intake end of the reversing air intake mechanism 8 is installed at the air outlet end of the air intake manifold 31, and the two air outlet ends of the reversing air intake mechanism 8 are respectively connected to the forward air intake pipe 32 and the reverse air intake pipe 33. A first air vent pipe 34 and a second air vent pipe 35 are provided in the tank wall of the mixing tank 1. All forward air outlet pipes 21 are connected to the air outlet end of the forward air intake pipe 32 through the first air vent pipe 34, and all reverse air outlet pipes 22 are connected to the air outlet end of the reverse air intake pipe 33 through the second air vent pipe 35.

[0042] like Figure 2 and Figure 3 As shown together, the reversing air intake mechanism 8 includes a three-way pipe 81, a connecting cavity 82 is provided inside the three-way pipe 81, a reversing column valve 83 is rotatably installed in the connecting cavity 82, the reversing column valve 83 is transmission-connected to a reversing drive motor 84, a reversing cavity 85 is provided at the axis of the reversing column valve 83, and a first air vent 86, a second air vent 87 and a third air vent 88 are provided on the circumference of the reversing column valve 83. The positions of the first air vent 86, the second air vent 87 and the third air vent 88 are respectively adapted to the air inlet end and the two air outlet ends of the three-way pipe 81.

[0043] In this embodiment, the motor housing of the reversing drive motor 84 is fixedly mounted on the outer wall of the three-way pipe 81 .

[0044] In this embodiment, the first vent 86 and the second vent 87 are coaxially arranged.

[0045] In this embodiment, the axis of the third vent 88 is perpendicular to the axis of the first vent 86 .

[0046] Moreover, the three-way pipe 81 is provided with an air inlet pipe port 811, a first air outlet pipe port 812 and a second air outlet pipe port 813. The air inlet pipe port 811 and the first air outlet pipe port 812 are coaxially arranged. The air inlet pipe port 811 is connected to the air outlet end of the air intake manifold 31, the first air outlet pipe port 812 is connected to the air inlet end of the forward air intake pipe 32, the axis of the second air outlet pipe port 813 is arranged perpendicular to the axis of the air inlet pipe port 811, and the second air outlet pipe port 813 is connected to the air inlet end of the reverse air intake pipe 33.

[0047] In this embodiment, the reversing drive motor 84 drives the reversing column valve 83 to rotate, so that the first air vent 86 is connected to the air inlet pipe 811, the second air vent 87 is connected to the first air outlet pipe 812, and when the third air vent 88 is facing away from the second air outlet pipe 813, the pure high-pressure nitrogen in the nitrogen source 4 enters the reversing chamber 85 through the air inlet manifold 31, the air inlet pipe 811 and the first air vent 86, and then enters the first air vent pipe 34 through the second air vent 87, the first air outlet pipe 812 and the forward air inlet pipe 32. The high-pressure nitrogen in the first air vent pipe 34 is then dispersed into each forward air outlet pipe 21, and the high-pressure nitrogen in the forward air outlet pipe 21 is sprayed into the mixing tank 1 along the tangential direction through the forward air outlet 23.

[0048] The reversing drive motor 84 drives the reversing column valve 83 to continue rotating, so that the first air vent 86 is connected to the second air outlet 813, and the third air vent 88 is connected to the air inlet 811. When the second air vent 87 is facing away from the second air outlet 813, the pure high-pressure nitrogen in the nitrogen source 4 enters the reversing chamber 85 through the air inlet manifold 31, the air inlet 811 and the third air vent 88, and then enters the second air vent pipe 35 through the first air vent 86, the second air outlet 813 and the reverse air inlet pipe 33. The high-pressure nitrogen in the second air vent pipe 35 is then dispersed into each reverse air outlet pipe 22, and the high-pressure nitrogen in the reverse air outlet pipe 22 is sprayed into the mixing tank 1 along the tangential direction through the reverse air outlet 24.

[0049] In this embodiment, an intermittent bidirectional airflow stirring operation is implemented, and the available sol solution is continuously subjected to bidirectional vortex mixing, thereby effectively improving the mixing efficiency and mixing effect of the available sol solution and alcohol.
