DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the following preferred embodiments are cited with reference to the accompanying drawings for further detailed description of the present utility model. However, it should be noted that many details listed in the specification are only for enabling the reader to have a thorough understanding of one or more aspects of the utility model, and these aspects of the present utility model can be implemented even without these specific details.
[0019] Please refer to Figures 1 to 3 , the present utility model provides a multi-layer rapid sedimentation tank for sugar industry production, and the technical solution is as follows:
[0020] It includes a vessel body 1, a vessel top 2 is provided at the top of the vessel body 1, two feed pipes 3 are symmetrically provided on the vessel top 2, a driving unit 4 is provided at the top of the vessel body 1, and a speed reduction mechanism 5 is provided on the output shaft of the driving unit 4. The output shaft of the driving unit 4 extends into the vessel body 1. A central pipe shaft mechanism 6 is provided at the center in the vessel body 1. A plurality of inclined disk mechanisms 7 are evenly distributed on the central pipe shaft mechanism 6. A dial arm mechanism 8 is provided on each inclined disk mechanism 7, and the uppermost inclined disk mechanism 7 is a guide disk mechanism 701 that cooperates with the two feed pipes 3. A plurality of juice inlets 9 are provided at the connection between the guide disk mechanism 701 and the central pipe shaft mechanism 6. A plurality of juice discharge ports 10 are opened at the positions corresponding to the plurality of inclined disk mechanisms 7 on the central pipe shaft mechanism 6. A plurality of inner ring pipes 11 are evenly distributed on the inner side wall of the vessel body 1, and each inner ring pipe 11 is located at the top of the corresponding inclined disk mechanism 7. The plurality of inner ring pipes 11 all extend outside the vessel body 1, and the plurality of inner ring pipes 11 are all connected to a connecting pipe 12. A juice discharge trough 13 is provided at the lower end of the outer side wall of the vessel body 1, and the connecting pipe 12 extends into the juice discharge trough 13. A plurality of manholes 14 are evenly distributed on the outer side wall of the vessel body 1. A platform ladder 15 is wound around the vessel body 1.
[0021] External sugar juice enters the guide disk mechanism 701 from the two feed pipes 3 at the vessel top 2, and then is guided by the guide disk mechanism 701 to enter the central pipe shaft mechanism 6 through a plurality of juice inlets 9, flows to the positions of the lower several inclined disk mechanisms 7 by gravity, and is discharged through a plurality of juice discharge ports 10. A plurality of dial arm mechanisms 8 are started to rotate for sedimentation and clarification; the sugar juice after sedimentation and clarification flows out from the inner ring pipes 11 at the corresponding height, flows into the juice discharge trough 13, and finally flows to the curved screen clear juice pipe for the next process;
[0022] The sedimentation tank is designed with 5 layers and a buffer layer, arranged in sequence from bottom to top. Each layer is equipped with annular pipe juice extraction, and different operating modes can be adopted according to different squeezing capacities; when operating at a low squeezing capacity of about 6000 t / d, juice is extracted from the 1st - 2nd layers; when operating at a normal squeezing capacity of about 8000 t / d, juice is extracted from the 1st - 3rd layers; at the same time, juice extraction from the 1st - 4th layers is reserved for operation at a high squeezing capacity above 8000 t / d; the 5th layer serves as a gas - dispersing and juice - inlet buffer layer, improving the anti - interference ability, effectively avoiding "bottom - reversal" caused by temperature fluctuations, achieving a working mode close to "static" sedimentation, and operating stably; the clarified juice after being processed under normal process is clear, without obvious floating scum or debris; one of the main advantages of the multi - layer sedimentation tank is its flexibility. According to the changes in the amount of cane juice and the quality of clarified juice, the number of sedimentation layers used can be adjusted at any time. This flexibility enables the system to operate efficiently under different working conditions, meeting the requirements during both peak and trough periods. Moreover, the design of the multi - layer sedimentation tank can effectively save energy and operating costs; the flux of the juice inlet and outlet holes of each sedimentation layer is set according to the normal distribution. The flux setting of the normal distribution helps to optimize the treatment effect of the entire multi - layer sedimentation tank system.
[0023] Each of the swash - plate mechanisms 7 and the corresponding inner annular pipes 11 are horizontally arranged; the inner annular pipe 11 is located at the top of the corresponding swash - plate mechanism 7, and the swash - plate mechanism 7 and the corresponding inner annular pipe 11 are horizontally arranged. In this way, the clarified liquid can enter the inner annular pipe 11 more evenly. This uniform liquid supply helps to maintain the liquid flow and sedimentation effect in the sedimentation tank, avoiding local agitation or poor sedimentation in the tank caused by uneven liquid entry; if the top of the swash - plate mechanism 7 is not horizontally aligned with the outlet of the inner annular pipe 11, it may cause water flow impact or liquid jet, which may affect the sedimentation effect and liquid - level stability in the sedimentation tank. By horizontal alignment, this kind of impact can be reduced, helping to maintain a calm state in the tank.
[0024] A plurality of annular baffles 16 are evenly distributed on the central pipe shaft mechanism 6, and each annular baffle 16 cooperates with the juice - discharging port 10; a plurality of juice - discharging ports 10 on the central pipe shaft mechanism 6 cooperate with the corresponding swash - plate mechanisms 7, and an annular baffle 16 is provided at the juice - discharging port 10 of each swash - plate mechanism 7. The annular baffle 16 is arranged from top to bottom and from small to large. The design of the annular baffle 16 can effectively separate the clarified liquid in the upper layer and the muddy juice in the lower layer in the swash - plate mechanism 7. The clarified liquid is usually in the upper layer and is relatively clear, while the muddy juice contains more suspended substances and solid particles. Through the annular baffle 16, the clarified liquid in the upper layer can smoothly flow to the inner annular pipe 11 or the treatment area, while the muddy juice is guided into the inner apron, preventing the two from mixing or cross - affecting. The flow direction of the muddy juice is separated from that of the clarified liquid, without interference with each other, maintaining the effectiveness and stability of the water treatment process;
[0025] Separating the clear juice and the muddy juice helps reduce the possible pollution risk. If the clear juice is mixed with the muddy juice, it may affect the efficiency of subsequent processing steps and even lead to problems such as unqualified water treatment or equipment damage. The annular baffle 16 effectively avoids this risk and maintains the stability and continuous operation ability of the water treatment system.
[0026] The said arm-pulling mechanism 8 includes multiple arm-pulling parts, and the number of arm-pulling parts of the arm-pulling mechanism 8 at the upper end of the device body 1 is half of that of the arm-pulling mechanism 8 at the lower end; there are five inclined disk mechanisms 7 in the device body 1, and there is a guiding disk mechanism 701 at the upper end. The five inclined disk mechanisms 7 are distributed successively from bottom to top. The number of arm-pulling parts on the first, second, and third inclined disk mechanisms 7 from bottom to top is set to four, while the number of arm-pulling parts on the fourth and fifth inclined disk mechanisms 7 is set to two. The difference lies in the different amounts of mud to be processed. The amount of mud in the lower layers is relatively large. Setting different numbers of arm-pulling parts at different levels can better adapt to the sedimentation situation and mud layer thickness of each sedimentation tank. By setting different numbers of arm-pulling parts at different levels, the mud layer of each sedimentation tank can be more precisely controlled and managed, which helps maintain the normal operation state of the sedimentation tank and prevent the mud layer from being too thick and affecting the sedimentation effect and cleaning efficiency of the tank; and the fifth layer is the steam-dispersing, juice-inletting, and buffering layer.
[0027] The bottom of the said device body 1 is conical, and the inclination angle of the conical part of the device body 1 is between 15° - 20°; the design of the conical bottom can help effectively concentrate the mud layer in the sedimentation tank to the central position at the bottom. Since the bottom is inclined towards the center point, the precipitated solid particles and mud tend to concentrate at the lowest point, which can facilitate the subsequent removal and treatment of the mud layer; the inclination angle of the conical bottom helps reduce the liquid agitation at the bottom of the tank because the solid particles and mud will naturally flow towards the central area along the inclined surface of the bottom and will not oscillate upstream and downstream at the bottom, which helps maintain the sedimentation stability of the sludge and prevent it from resuspending in the water; setting the inclination angle of the sedimentation tank bottom between 15° - 20° can take into account improving the sedimentation effect, facilitating the removal of the mud layer, reducing energy consumption, and improving the stability of the liquid in the tank.
[0028] There is a gas-dispersing box outside the said device body 1; a highly efficient gas-dispersing box is equipped outside the device body 1 to fully disperse the gas dissolved in the cane juice after secondary heating of the cane juice and the overheated cane juice steam, preventing the cane juice from boiling and disturbing in the sedimentation tank and improving the sedimentation and clarification effect.
[0029] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
