Description

Technical Field

[0001] The present invention relates to the technical field of centrifuges, and particularly to a centrifuge for the preparation of lotus leaf dew health drink. Background Art

[0002] Lotus leaf is a green natural raw material with low price, strong functionality and wide availability. There are rich lotus leaf resources in some areas, which are widely distributed and inexpensive. Due to the strong seasonality of harvesting, the resources are extremely wasted because they cannot be fully utilized and effectively developed. Therefore, the development and research of a lotus leaf dew health drink can make more full use of effective resources and achieve sustainable economic development. The existing production process of lotus leaf dew is as follows: mint heating extraction, filtering of crude lotus leaf, ultra-fine processing, heating extraction, filtering, blending, filtering, sterilization, filling and sealing, sterilization, cooling, finished product and inspection.

[0003] During the production of lotus leaf dew, a centrifuge can carry out the filtering work for it. The existing document with the publication number of CN116532250B discloses a pull-bag type scraper lower discharge centrifuge, which belongs to the technical field of discharge centrifuges. The present invention is provided with: a centrifuge housing, an inner cylinder, an inner cylinder motor, a filter cloth bag, a pull-bag unit, a feeding unit, a distributor, a scraper unit, an image detection unit, an inner cylinder weight detection device, a washing and sprinkling device, and a central control system. The central control system can analyze the feeding situation through the inner cylinder weight transmitted back by the inner cylinder weight detection device, so as to control whether the feeding unit continues to receive the raw material input, and determine the raw material distribution situation through the cloth image in the inner cylinder collected by the image detection unit, so as to adjust the rotation speed of the distributor, and adjust the rotation speed of the inner cylinder motor according to the fluidity of the raw material, so that the raw materials in the filter cloth bag are evenly distributed, reducing the equipment failure rate and improving the efficiency of the centrifugal work.

[0004] For the above-mentioned centrifuge, when discharging the filter bag, it can only rely on pulling the filter bag up and down to make the filter cake residue inside the filter bag fall off from the filter bag. When pulling the filter bag, although the lumpy filter cake will fall along the filter bag by its own gravity, it is inevitable that some fine powder residues will be left and adsorbed on the filter bag. Over time, the residual powder will gradually accumulate, resulting in a reduction in the filtering area of the filter bag, thereby reducing the penetrability and flow rate of the liquid, and further reducing the separation efficiency of the centrifuge. Summary of the Invention

Four mounting grooves are opened inside the discharge barrel; An auxiliary discharge assembly, which is used to help the residue of the filter cake layer inside the filter bag break away from the filter bag. The auxiliary discharge assembly includes a driving member, an auxiliary discharge member, and a displacement member. The driving member is used to drive the auxiliary discharge member and the displacement member by means of the driving force of the bag-pulling discharge mechanism. The displacement member is used to help the auxiliary discharge member change its position in the filter bag; The driving member includes a driving ring sliding on the inner surface of the centrifugal barrel and driving rod heads respectively rotating inside the four mounting grooves. The driving ring is connected to the connecting ring frame. One end of each of the four driving rod heads is fixed with a hollow strip, and a driving rod frame slides inside each of the four hollow strips.

[0007] Preferably, the auxiliary discharge member includes two air storage shells fixed above the mounting base and a plurality of mounting frames fixed inside the housing. Two of the hollow strips are both below one of the air storage shells, and the other two hollow strips are both below the other air storage shell. Piston plates slide inside the two air storage shells. One end of two of the driving rod frames extends into the same air storage shell and is fixed below the piston plate; A plurality of air inlets and a plurality of air outlets are opened above the two air storage shells. Solenoid valves are arranged inside the plurality of air inlets and the plurality of air outlets. Pressure sensors are arranged inside the two air storage shells. One end of each of the plurality of mounting frames is provided with a telescopic tube. One end of each of the plurality of air outlets is fixedly connected to one end of the plurality of telescopic tubes through a hose.

[0008] Preferably, the displacement member includes a sliding frame sliding outside the housing and the two air storage shells and telescopic traction members respectively arranged below the plurality of mounting frames. Both sides below the sliding frame are fixed with lifting frames. One of the lifting frames is fixed between two of the driving rod frames, and the other lifting frame is fixed between the other two driving rod frames. A plurality of traction ropes are fixed above the lifting frames. One end of each of the plurality of traction ropes extends into the housing, and one end of each of the plurality of traction ropes is respectively connected to the plurality of telescopic traction members.

[0009] Preferably, the telescopic traction member includes a fixed guide bar fixed below the mounting frame and a connecting guide bar fixed to one end of the telescopic tube. A telescopic guide bar slides between the fixed guide bar and the connecting guide bar. One end of the traction rope extends below the mounting frame and is fixedly connected to one end of the connecting guide bar.

[0010] Preferably, the bag pulling and discharging mechanism includes a main shaft seat arranged inside the centrifugal barrel. An air control mechanism is arranged inside the main shaft seat.

Then the driving rod frame pushes the piston plate upward, and the gas will enter the telescopic tube through the exhaust port and the hose. The airflow ejected from the exhaust nozzle blows the residue on the filter bag towards the discharge cylinder, which helps to improve the sufficiency of discharging inside the filter bag, effectively reducing the reduction of the filtration area, liquid penetration, and flow velocity of the filter bag caused by the accumulation of residues on the filter bag, and improving the discharging efficiency and the separation efficiency of the centrifuge.

[0015] 2. During the rising of the driving rod frame, the lifting frame will be pushed to move the sliding frame upward. During the upward movement of the sliding frame, the traction rope will become loose, and the telescopic tube will slide downward through the gravity ring arranged at one of its ends. Restricted by the relative sliding of the fixed guide bar, the connecting guide bar, and the telescopic guide bar, the downward sliding direction and distance can evenly send the airflow to a position on the filter bag that is relatively far from the starting position of the telescopic tube, fully helping the filter bag to discharge.

[0018] The following further elaborates on the above and other technical features and advantages of the present invention with reference to the accompanying drawings.

[0019] The present invention provides a technical solution: a centrifuge for preparing a lotus leaf dew health drink, as Figures 1-6As shown in the figure, it includes a mounting base 1 and an auxiliary discharge assembly 8. Above the mounting base 1, there is a housing 2. Inside the housing 2, there is a centrifugal barrel 3. Inside the centrifugal barrel 3, there is a filter bag 4. One end of the filter bag 4 is fixed with a connecting ring frame 5. Below the housing 2, there is a discharge tube 6. The discharge tube 6 is communicated with the discharge port below the centrifugal barrel 3. Inside the centrifugal barrel 3, there is a bag-pulling and discharging mechanism 7. The bag-pulling and discharging mechanism 7 includes a main shaft seat 71 arranged inside the centrifugal barrel 3. Inside the main shaft seat 71, there is a pneumatic control mechanism 72. A protective cover 73 slides outside the main shaft seat 71. The inside of the protective cover 73 is connected to the telescopic end of the pneumatic control mechanism 72, and the protective cover 73 is fixedly connected to the connecting ring frame 5. Four mounting grooves 9 are opened inside the discharge tube 6. Two of the mounting grooves 9 are in a group. The four mounting grooves 9 can be regarded as two groups, and the two groups are arranged at equal intervals on the discharge tube 6. Above the housing 2, there is a sealing cover 10. Above the mounting base 1, there is a flip mechanism 11 for lifting or closing the sealing cover 10. The flip mechanism 11 is connected to the sealing cover 10. Inside the sealing cover 10, there is an inclined plate distributor 12, a feed pipe 13, a level detection and controller 14, a washing pipe 15, and a scraping mechanism 16. Below the housing 2, there is a drain pipe 17 for discharging the filtered liquid. Below the mounting base 1, there is a driving mechanism 18 for driving the centrifugal barrel 3 to rotate.

[0020] As Figures 1-6 shown, the auxiliary discharge assembly 8 is used to help the residue of the filter cake layer inside the filter bag 4 break away from the filter bag 4, increasing the sufficiency and efficiency of discharging. The auxiliary discharge assembly 8 includes a driving force member, an auxiliary discharge member, and a displacement member. The driving force member is used to drive the auxiliary discharge member and the displacement member by means of the driving force of the bag-pulling and discharging mechanism 7. The auxiliary discharge member, under the drive of the driving force member, blows the residue of the filter cake layer inside the filter bag 4 out of the filter bag 4 when the filter bag 4 is pulled. The displacement member is used to help the auxiliary discharge member change its position in the filter bag 4 so that the auxiliary discharge member can blow out the residue inside the filter bag 4 more fully and effectively. The driving force member includes a driving ring 81 sliding on the inner surface of the centrifugal barrel 3 and driving rod heads 82 respectively rotating inside the four mounting grooves 9. Since the four mounting grooves 9 are divided into two groups of two, a total of two groups, the driving rod heads 82 respectively installed in the four mounting grooves 9 can also be regarded as two groups of two, a total of two groups. Among them, the driving ring 81 is connected to the connecting ring frame 5. One end of each of the four driving rod heads 82 is fixed with a hollow bar 83. The hollow bars 83 are located below the mounting base 1, and a driving rod frame 84 slides inside each of the four hollow bars 83.

[0021] As Figures 1-6As shown in the figure, the air assisting component includes two air storage shells 85 fixed above the mounting base 1 and multiple mounting frames 86 fixed inside the outer shell 2. The two air storage shells 85 are respectively located above the driving rod frames 84 corresponding to the two groups of driving rod heads 82. Among them, the two hollow bars 83 grouped together are both located below one of the air storage shells 85, and the other two hollow bars 83 grouped together are both located below the other air storage shell 85. Piston plates 87 are slidably arranged inside the two air storage shells 85. One end of the two driving rod frames 84 grouped together extends into the same air storage shell 85 and is fixed below the piston plate 87. A plurality of air inlets 88 and a plurality of air outlets 89 are provided above the two air storage shells 85. Electromagnetic valves 810 are arranged inside the plurality of air inlets 88 and the plurality of air outlets 89. Pressure sensors 811 are arranged inside the two air storage shells 85 for real-time monitoring of the pressure change inside the air storage shells 85. Among them, the pressure sensors 811 and the electromagnetic valves 810 are both connected to an external PLC controller through the prior art to respond to control signals. The PLC controller processes the signals of the pressure sensors 811 and controls the opening and closing of the corresponding electromagnetic valves 810. First, it is necessary to set a threshold value, set the high and low threshold values of the pressure according to the system requirements to define the position and function of the piston plate 87. One end of each of the multiple mounting frames 86 is provided with a telescopic tube 812. One end of each of the multiple air outlets 89 is fixedly connected to one end of the multiple telescopic tubes 812 through a hose. The telescopic tubes 812 that are not connected to the air outlets 89 can be connected to other hoses that have been connected to the air outlets 89 through a hose.

[0022] As Figures 1-6 shown in the figure, the shifting component includes a sliding frame 813 slidably arranged outside the outer shell 2 and the two air storage shells 85 and telescopic traction components respectively arranged below the multiple mounting frames 86. Lifting frames 814 are fixedly arranged on both sides below the sliding frame 813. One of the lifting frames 814 is fixed between the two driving rod frames 84 grouped together, and the other lifting frame 814 is fixed between the other two driving rod frames 84 grouped together. A plurality of traction ropes 815 are fixedly arranged above the lifting frames 814. The traction ropes 815 can limit their trajectories through a plurality of traction wheels. One end of each of the plurality of traction ropes 815 extends into the inner part of the outer shell 2, and a sealing sleeve is arranged at the penetration point to increase the sealing performance of the penetration point. One end of each of the plurality of traction ropes 815 is respectively connected to the plurality of telescopic traction components. Among them, the telescopic traction component includes a fixed guiding bar 816 fixed below the mounting frame 86 and a connecting guiding bar 817 fixed at one end of the telescopic tube 812. A telescopic guiding bar 818 is slidably arranged between the fixed guiding bar 816 and the connecting guiding bar 817. The number of the telescopic guiding bars 818 can be adjusted and set according to specific dimensions. The fixed guiding bar 816, the telescopic guiding bar 818 and the connecting guiding bar 817 are slidably connected to each other. One end of the traction rope 815 extends below the mounting frame 86 and is fixedly connected to one end of the connecting guiding bar 817.

[0023] When in use, after the lotus leaf dew is heated and extracted for a certain period of time, the suspension is fed into the inclined disc distributor 12 through the feed pipe 13. Driven by the drive mechanism 18, the centrifugal barrel 3 rotates at a constant speed, and the inclined disc distributor 12 evenly distributes the suspension in the filter bag 4 and the centrifugal barrel 3, wherein the solid phase is intercepted by the filter bag 4, and a filter cake layer is formed in the filter bag 4, and the filtered liquid is discharged through the drain pipe 17. After the filter cake layer gradually thickens and touches the material level detection controller 14, the feeding is stopped, and the centrifuge dehydrates at high speed to discharge the filtered liquid, and then passes through the washing pipe. 15 washes the filter cake, centrifuges and dehydrates it again, and scrapes the filter cake off through the scraper mechanism 16. The material is discharged from the centrifuge through the discharge barrel 6. The scraper mechanism 16 is reset, and the remaining filter cake is pulled down by the air control mechanism 72 in the bag pulling discharge mechanism 7 to pull the protective cover 73 downward. The protective cover 73 pulls down one end of the filter bag 4 through the connecting ring frame 5 to straighten the filter bag 4, so that the remaining filter cake is peeled off from the filter bag 4 and discharged from the discharge barrel 6. After the air control mechanism 72 is reset, the filter bag 4 is pulled again through the protective cover 73 to discharge the residue inside the filter bag 4.

[0024] When the connecting ring frame 5 is pulled by the bag unloading mechanism 7, the connecting ring frame 5 will push the driving ring 81 connected to it to move downward, and the driving ring 81 will press the driving rod head 82 downward, thereby driving the hollow bar 83 connected to it to tilt upward, and the hollow bar 83 will push the piston plate 87 upward through the driving rod frame 84. At the same time, the pressure sensor 811 will transmit a signal to the PLC controller through the detected pressure value to control the solenoid valve 810 in the exhaust port 89 to open. At this time, the solenoid valve 810 of the air inlet 88 is closed, and then the gas in the air storage shell 85 will enter the telescopic tube 812 through the exhaust port 89 and the hose, and be ejected through the exhaust nozzle at one end of the telescopic tube 812. The ejected airflow blows the residue on the filter bag 4 toward the discharge barrel 6, helping to improve the adequacy of the internal discharge of the filter bag 4, effectively reducing the accumulation of residue on the filter bag 4, which causes the filter area, liquid penetration and flow rate of the filter bag 4 to decrease, thereby improving the discharge efficiency and the separation efficiency of the centrifuge. During the rising of the driving rod frame 84, the lifting frame 814 will push the sliding frame 813 upward. During the upward movement of the sliding frame 813, the traction rope 815 will loosen, and the telescopic tube 812 will slide down through the gravity ring provided at one end thereof. In this way, while blowing out the airflow, the airflow can be evenly sent to a position on the filter bag 4 that is relatively far from the starting position of the telescopic tube 812, thereby fully helping the discharge.

[0025] When the pulling bag discharging mechanism 7 is reset, the piston plate 87 will slide down to its original position due to the self - gravity of the sliding frame 813 and the lifting frame 814. When the piston plate 87 slides down, the PLC controller controls the solenoid valve 810 in the air inlet 88 to open and the solenoid valve 810 in the air outlet 89 to close by receiving the internal pressure value of the air storage shell 85 detected by the pressure sensor 811, so as to ensure that the external air can be pumped into the air storage shell 85 for storage and used for the next discharging.

[0026] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
