DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] In order to optimize the gas dispersion effect in the central area and facilitate automatic adjustment of the stirring effect of the blades according to the rotation speed of the disk, as an embodiment of the present invention, Figure 1 As shown, a six-parabola disc turbine stirring blade described in the present invention includes a disc 1, which is assembled and connected by bolts and fixing plates, and a plurality of groups of mounting holes 2 are provided on the disc 1, and the mounting holes 2 are connected to the flange of the stirring shaft by bolts, and the upper surface of the disc 1 is provided with a plurality of groups of circumferentially distributed upper arc leaves 3, and the lower surface of the disc 1 is provided with a plurality of groups of lower arc leaves 4 corresponding to the upper arc leaves 3, and the upper arc leaves 3 and the lower arc leaves 4 are combined into a parabola, and the disc 1 is provided with a plurality of groups of through-set assembling holes 5, and one side of the upper arc leaves 3 and the lower arc leaves 4 are fixedly connected with a mounting plate 6, and the mounting plate 6 is provided with a plurality of groups of connecting holes, and the connecting holes are fixedly connected to the assembling holes 5 by bolts, and the upper arc leaves 3 and the lower arc leaves 4 are provided with a plurality of groups of through-set first openings 7.

[0029] When in use, the mounting hole 2 is connected to the flange of the stirring shaft by bolts. When the stirring shaft rotates, the disc 1 is driven to rotate. When the disc 1 rotates, the gas passes through the first opening 7. The gas dispersion effect in the central area is optimized by the first opening 7. Compared with the gas dispersed only outward, the gas concentration on the upper and lower sides of the parabola is significantly increased, and the stirring power is also reduced.

[0030] The installation positions of the upper arc leaf 3 and the lower arc leaf 4 are adjusted by means of the connection holes and the assembly holes 5, so that the sizes of the upper arc leaf 3 and the lower arc leaf 4 after installation can be changed according to actual usage conditions, thereby further improving the convenience of use.

[0031] For example, Figure 2 , Figure 3 , Figure 4As shown, the present invention also includes that a movable plate 8 is provided on the inner side of the upper arc leaf 3 and the lower arc leaf 4, and a slot 9 is provided on the movable plate 8. A slide groove 10 parallel to the radial direction of the disk 1 is provided on the outer side of the movable plate 8. A slider 11 is provided on the inner side of the upper arc leaf 3 and the lower arc leaf 4. The slider 11 is located in the slide groove 10 and is slidably connected to the slide groove 10. A first reset spring 12 is fixedly connected between the slide groove 10 and the inner wall of the slider 11.

[0032] When in use, the disc 1 rotates to drive the upper arc blade 3 and the lower arc blade 4 to rotate synchronously. As the rotation speed of the disc 1 increases, the centrifugal force generated by the rotation of the disc 1 drives the movable plate 8 to move outward, so that the distance the movable plate 8 moves outward can be adjusted according to the rotation speed of the disc 1, thereby improving the stirring effect in the fermentation tank and further improving the convenience of use.

[0033] When the moving plate 8 moves, the slider 11 is slidably connected with the slide groove 10, so as to improve the moving stability of the moving plate 8. At the same time, as the moving plate 8 moves, the slider 11 squeezes the first return spring 12 in the slide groove 10; when the stirring work is completed, the disc 1 no longer rotates, and the first return spring 12 is used to return and squeeze the moving plate 8, so as to facilitate the moving plate 8 to return to its initial state.

[0034] In order to automatically improve the stirring effect and the gas dispersion effect according to the rotation speed of the disk 1, for example, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the present invention also includes that the movable plate 8 is provided with a second opening 13 that is arranged through it; when the six-parabolic disc turbine stirring blade is stationary, the second opening 13 is staggered with the first opening 7; as the speed of the six-parabolic disc turbine stirring blade increases, the movable plate 8 moves radially outward along the disc 1 so that the number of the blocked second openings 13 gradually decreases.

[0035] During use, when the disc 1 rotates, it drives the movable plate 8 to move outward. After the movable plate 8 moves a certain distance, the second opening 13 coincides with the first opening 7. The first opening 7 can be used to improve the gas dispersion effect of the central area when the disc 1 rotates. At the same time, as the rotation speed of the disc 1 increases, the distance that the movable plate 8 is driven outward by the centrifugal force becomes larger. When the movable plate 8 continues to move outward for a certain distance, the second opening 13 on the movable plate 8 is no longer blocked by the upper arc leaf 3 and the lower arc leaf 4. The second opening 13 can be used to further optimize the gas dispersion effect in the central area, and it is convenient to automatically improve the stirring effect and the gas dispersion effect according to the rotation speed of the disc 1.

[0036] In order to facilitate cleaning of the first opening 7, for example, Figure 4 , Figure 5 , Figure 8 As shown, the present invention also includes that the upper arc leaf 3 and the lower arc leaf 4 are both installed with movable grooves 14, and a pressure supply structure is installed in the movable grooves 14, and the inner wall of the first opening 7 is provided with a mounting groove 15, and the mounting groove 15 is fixedly connected with an expansion ring 16, and the expansion ring 16 is connected to the pressure supply structure; when the movable plate 8 moves outward in the radial direction of the disc 1, the pressure of the pressure supply structure is reduced, thereby causing the expansion ring 16 to contract.

[0037] During use, when the disc 1 rotates, it drives the movable plate 8 to move outward. When the movable plate 8 moves outward, the pressure supply structure is used to shrink the expansion ring 16 in the first opening 7, so as to improve the ventilation efficiency of the first opening 7. When the gas in the central area passes through the first opening 7, the first opening 7 is used to improve the dispersion effect of the gas. When the stirring work is completed and the disc 1 no longer rotates, the first return spring 12 is used to drive the movable plate 8 to return to its original position. At this time, the pressure supply structure is used to drive the expansion ring 16 to expand. When the expansion ring 16 expands, it can squeeze the inside of the first opening 7 to prevent the material from clogging the first opening 7 during the stirring process. The expansion ring 16 is used to facilitate the cleaning of the first opening 7, and at the same time, it is convenient to stir the next group of materials when it is used again in the future to ensure the stirring effect.

[0038] In order to facilitate cleaning of the second opening 13, for example, Figure 4 , Figure 5 , Figure 7 As shown, the present invention also includes that a movable groove 17 is provided on the inner side of the upper arc leaf 3 and the lower arc leaf 4, and a movable block 18 is sealed and slidably connected in the movable groove 17, and several groups of the movable blocks 18 correspond to the moving direction of the second opening 13, and a second return spring 19 is fixedly connected between the movable block 18 and the inner wall of the movable groove 17, and the movable groove 17 is connected to the pressure supply structure through a channel.

[0039] When in use, when the disc 1 rotates, it drives the moving plate 8 to move outward. When the moving plate 8 moves outward, the pressure supply structure no longer squeezes the moving block 18 to move outward, and relies on the second return spring 19 to drive the moving block 18 to move inward into the moving groove 17, so as to facilitate the moving plate 8 to move outward. As the rotation speed of the disc 1 increases, the distance that the moving plate 8 moves outward increases. The second opening 13 can further improve the dispersion effect of the gas, so as to facilitate the automatic adjustment of the dispersion effect of the gas according to the rotation speed of the disc 1.

[0040] When the stirring work is completed and the disc 1 stops rotating, the first reset spring 12 drives the movable plate 8 to quickly reset to the initial state. At the same time, the pressure supply structure is connected with the movable groove 17 through the channel, and the movable block 18 is squeezed to move outward. When the movable block 18 moves outward, it corresponds to the second opening 13, and the inside of the second opening 13 is cleaned by the movable block 18, so that the next group of materials can be stirred when it is used again to ensure the stirring effect.

[0041] For example, Figure 4 , Figure 5 , Figure 6 As shown, the present invention also includes that the pressure supply structure includes an airbag 20 installed in the movable groove 14, the side of the airbag 20 away from the disc 1 is connected to the movable block 21, the side of the movable block 21 away from the airbag 20 and the inner wall of the movable groove 14 are fixedly connected with an extrusion spring 22, the airbag 20 is in extrusion contact with one side of the movable block 21 in the initial state, the end of the airbag 20 away from the movable block 21 is connected to an air outlet pipe 23, and the air outlet pipe 23 is connected to a plurality of groups of expansion rings 16 and the movable groove 17 through a channel.

[0042] When in use, when the disc 1 rotates, the centrifugal force generated by the rotation of the disc 1 drives the movable block 21 to move outward in the movable groove 14, and at the same time squeezes the squeezing spring 22, so that the squeezing spring 22 accumulates force, and the movable block 21 no longer squeezes the airbag 20 when moving. At this time, the expansion ring 16 contracts and no longer expands, thereby opening the first opening 7, and relying on the first opening 7 to improve the dispersion effect of the gas; when the airbag 20 is no longer squeezed, the second return spring 19 drives the movable block 18 to move inward, thereby driving the movable plate 8 to move outward after the rotation speed of the disc 1 reaches a certain value; when the movable plate 8 moves outward for a certain distance, relying on the second opening 13, the dispersion effect of the gas can be further improved, thereby facilitating the automatic adjustment of the number of the first opening 7 and the second opening 13 put into use according to the rotation speed of the disc 1;

[0043] When the stirring work is completed and the disc 1 no longer rotates, the first reset spring 12 drives the movable plate 8 to reset and move, and the extrusion spring 22 squeezes the movable block 21 to reset and move. When the movable block 21 resets and moves, it squeezes the airbag 20. The gas in the airbag 20 is connected with the expansion ring 16 and the movable groove 17 through the outlet pipe 23 and the channel, driving the expansion ring 16 to expand and the moving block 18 to move outward. The first opening 7 is cleaned by the expansion ring 16, and the second opening 13 is cleaned by the moving block 18, so as to prevent the material from clogging the first opening 7 and the second opening 13, affecting the stirring effect of the subsequent materials.

[0044] For example, Figure 2As shown, the present invention also includes that a plurality of groups of arc-shaped fixing plates 24 are fixedly connected between the upper arc leaf 3 and the lower arc leaf 4 , and the arc-shaped fixing plates 24 are located on the outer sides of the upper arc leaf 3 and the lower arc leaf 4 .

[0045] When in use, the arc-shaped fixing plate 24 can improve the stability between the upper arc leaf 3 and the lower arc leaf 4 .

[0046] As an embodiment of the present invention, the disc 1 of the present invention is formed by splicing two semicircles, and the upper arc leaf 3 and the lower arc leaf 4 both have 6 leaves. It should be noted that the disc 1 of the present invention can be spliced ​​by splicing four fan-shaped circles, in which case the upper arc leaf 3 and the lower arc leaf 4 both have 8 leaves.

[0047] The present invention also provides a stirring device, comprising the above-mentioned six-paraboloid disc turbine stirring blade. It should be noted that the device can be a fermentation tank, in which case the six-paraboloid disc turbine stirring blade is arranged on the rotating shaft at the bottom of the fermentation tank and is detachably connected through the disc 1 and the flange on the rotating shaft.

[0048] When the present invention is in use, the mounting hole 2 is connected to the flange of the stirring shaft by means of bolts. When the stirring shaft rotates, the disc 1 is driven to rotate. When the disc 1 rotates, the centrifugal force generated by the rotation of the disc 1 drives the movable block 21 to move outward in the movable groove 14, and at the same time squeezes the squeezing spring 22, so that the squeezing spring 22 accumulates force. When the movable block 21 moves, it no longer squeezes the airbag 20. At this time, the expansion ring 16 contracts and no longer expands, thereby opening the first opening 7. The gas dispersion effect in the central area is optimized by means of the first opening 7. Compared with the gas that is only dispersed outward, the gas concentration on the upper and lower sides of the parabola is significantly increased, and the stirring power is also reduced.

[0049] When the airbag 20 is no longer squeezed, the second return spring 19 drives the moving block 18 to move inward. As the rotation speed of the disc 1 increases, the centrifugal force generated by the rotation of the disc 1 drives the moving plate 8 to move outward, so that the distance the moving plate 8 moves outward can be adjusted according to the rotation speed of the disc 1, thereby improving the stirring effect in the fermentation tank and further improving the convenience of use.

[0050] When the disc 1 rotates, it drives the moving plate 8 to move outward. After the moving plate 8 moves a certain distance, the second opening 13 coincides with the first opening 7. The first opening 7 can improve the gas dispersion effect of the central area when the disc 1 rotates. At the same time, as the rotation speed of the disc 1 increases, the distance that the moving plate 8 is driven outward by the centrifugal force becomes larger. When the moving plate 8 continues to move outward for a certain distance, the second opening 13 on the moving plate 8 is no longer blocked by the upper arc leaf 3 and the lower arc leaf 4. The gas dispersion effect of the central area can be further optimized by the second opening 13. At the same time, it is convenient to automatically improve the stirring effect and the gas dispersion effect according to the rotation speed of the disc 1.

[0051] When the stirring work is completed and the disc 1 no longer rotates, the first reset spring 12 drives the movable plate 8 to reset and move, and the extrusion spring 22 squeezes the movable block 21 to reset and move. When the movable block 21 resets and moves, it squeezes the airbag 20. The gas in the airbag 20 is connected with the expansion ring 16 and the movable groove 17 through the outlet pipe 23 and the channel, driving the expansion ring 16 to expand and the moving block 18 to move outward. The first opening 7 is cleaned by the expansion ring 16, and the second opening 13 is cleaned by the moving block 18, so as to prevent the material from clogging the first opening 7 and the second opening 13, affecting the stirring effect of the subsequent materials.

[0052] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
