Description

Technical Field

[0001] This invention relates to a production equipment for coated tannic acid feed additives. Background Technology

[0002] Tannic acid produced from gallnut is used as a feed additive to improve animal growth performance and intestinal health. To address issues such as tannic acid's moisture absorption, oxidation inactivation, and poor palatability, a coating treatment method is currently used. To enhance the effectiveness of tannic acid in feed, the extraction and purification of tannic acid is crucial.

[0003] To facilitate the extraction and purification of tannic acid from gallnuts, patent application CN213951050U provides a tannic acid purification and extraction device. This device, through the coordinated use of a housing, insulation shell, temperature sensor, heating element, water inlet pipe, support rod, crushing box, feeding pipe, crushing roller, feed pipe, second motor, rotating rod, crushing blade, temperature controller, stirring rack, discharge pipe, filter box, filter frame, slide rail, valve, connecting rod, first motor, gear, fixing rod, frame, ultrafiltration membrane, and liquid pump, solves the problems of poor purification and extraction efficiency, inconvenience in multi-stage crushing of gallnuts, which easily affects the purification and extraction effect of tannic acid, and difficulty in separating gallnut residue and extract after gallnut extraction, thus reducing the practicality of the tannic acid purification and extraction device. However, in existing technologies, after the gallnuts are crushed and soaked in the filter chamber before filtration, the initial liquid level in the chamber is high when the valve is opened, resulting in a high flow rate from the valve to the filter chamber. As the liquid gradually flows out, the pressure at the bottom of the chamber decreases, and the flow rate also decreases. Therefore, the flow rate of the liquid to the filter chamber can be too fast or too slow, leading to insufficient filtration and unstable quality of the produced tannic acid. In addition, the filter screen used for tannic acid extraction is only a single layer and is fixed. Even after a short period of use, impurities can clog the filter screen, necessitating shutdown for cleaning or replacement, thus reducing the efficiency of tannic acid production. In order to achieve online cleaning of the filter screen, the wastewater treatment device provided by patent CN207024776U provides a multi-layer automatic sewage discharge filter screen. However, this device still has the problems of impurity leakage caused by all filter plates opening at the same time, and the inability to close the filter plates in time by spring force alone after they have opened. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art by providing a production equipment for coated tannic acid feed additives that produces stable quality and high production efficiency.

A disc spring is provided between the upper end face of the second conical sleeve and the lower end face of the support part. A first channel is provided in the upper part of the second conical sleeve, and a second channel is provided in the lower part of the second conical sleeve. The first channel connects the first annular cavity and the second annular cavity, and the second channel connects the second annular cavity and the outlet of the discharge pipe. A diverting cone is formed on the bottom inner surface of the second conical sleeve. The cone angle of the first conical sleeve relative to the center line of the discharge pipe is smaller than the cone angle of the second conical sleeve relative to the center line of the discharge pipe. The filtration device includes an upper filter screen, an upper pin, an upper stop block, an upper collection trough, an upper drain valve, a lower filter screen, a lower pin, a lower stop block, a lower collection trough, and a lower drain valve. The upper filter screen is rotatably connected to the inner wall of the filter box via the upper pin. A coil spring is fitted onto the upper pin. An upper collection trough is located below the end of the upper filter screen away from the upper pin. An upper stop block is fixed to the inner wall of the filter box above the upper collection trough. A lower filter screen is located below the upper filter screen and is rotatably connected to the inner wall of the filter frame via the lower pin. A coil spring is fitted onto the lower pin. The filter is equipped with a coil spring. A lower collection trough is located below the end of the lower filter screen away from the upper pin. A lower stop block is fixed on the inner wall of the filter box and above the lower collection trough. An interlocking device is provided between the upper and lower filter screens. The interlocking device includes an upper magnetic block fixed on the lower surface of the upper filter screen and a lower magnetic block provided on the upper surface of the lower filter screen. The upper magnetic block is connected to the upper filter screen through a connecting rod. A return water component with a triangular cross section is provided below both the upper and lower filter screens. The length of the return water component extending inward is greater than the length of the upper and lower collection troughs extending inward. A liquid pump is fixedly connected to the rear side of the filter box. The inlet of the liquid pump is connected to the bottom of the filter box cavity through a pipe. An ultrafiltration membrane is fixed on the box body. The outlet of the liquid pump is connected to the inlet of the ultrafiltration membrane through a pipe. The filter box also includes a drying box and a fluidized bed. The outlet of the ultrafiltration membrane is connected to the inlet of the drying box through a pipe. A powder outlet is provided at the bottom of the drying box, which is connected to the inlet of the fluidized bed.

[0006] Furthermore, connecting rods are fixedly connected to the four corners of the bottom of the box, and filter boxes are fixedly connected to the bottom of the connecting rods.

[0007] Furthermore, several rows of discontinuous support protrusions are provided on the inner surface of the second cone sleeve.

[0008] Furthermore, an upper drain valve for controlling sewage discharge is installed on the pipe connecting the upper collection tank to the outside, and a lower drain valve for controlling sewage discharge is installed on the pipe connecting the lower collection tank to the outside.

[0009] Furthermore, the upper surfaces of both the upper and lower blocks are inclined.

[0010] Furthermore, a base is provided at the bottom of the filter box.

[0011] The beneficial effects of this invention are as follows: 1. An automatic adjustment device is installed at the lower part of the discharge pipe, including a first conical sleeve and a second conical sleeve with different tapers. The first conical sleeve can slide into the second conical sleeve. A first annular cavity is formed between the outer surface of the first conical sleeve and the inner surface of the second conical sleeve. A second annular cavity is formed between the outer surface of the second conical sleeve and the inner surface of the discharge pipe. The first conical sleeve includes an L-shaped support part and a flexible part. A disc spring is installed between the upper end face of the second conical sleeve and the lower end face of the support part. The device automatically reduces the flow area at high liquid levels and automatically increases the flow area at low liquid levels. This achieves a smaller fluctuation in the velocity of the liquid flowing into the filter box under different liquid level conditions, solving the problem of insufficient filtration caused by excessively fast or slow liquid flow into the filter box, resulting in unstable quality of tannic acid.

[0012] 2. An automatic cleaning filtration device is installed inside the filter box. The filtration device includes a rotatable upper filter screen and a lower filter screen. An interlocking device is installed between the upper and lower filter screens. When the upper filter screen is tilted downwards to open, the upper magnetic block fixed on the lower surface of the upper filter screen will move downwards accordingly. The attraction between the upper and lower magnetic blocks increases, preventing the lower filter screen from falling. This ensures that the lower and upper filter screens do not open at the same time, improving the reliability of the filtration device. A triangular cross-section return water component is installed below both the upper and lower filter screens. This can cause turbulence and backflow of the media in the upper and lower filter screens. The upward backflow of the media can help the opened upper and lower filter screens to quickly abut against the upper and lower baffles, solving the problem that the filter plates cannot be closed in time by spring force alone after opening. At the same time, the backflow of the media can also help impurities on the filter screen to better detach from the filter screen and slide into the collection tank. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0018] Figure 1-4 A production device for coated tannic acid feed additives is shown. The device includes a housing 1, with a water inlet pipe 5 connected to the left side of the top of the housing 1 and a feed pipe 10 connected to the left side of the top of the housing 1. Crushed gallnut powder is fed into the housing 1 through the feed pipe 10. A motor 11 is fixedly connected to the center of the top of the housing 1. The output shaft of the motor 11 extends to the top of the inner cavity of the housing 1 and is fixedly connected to a rotating rod 12. A stirring blade 13 is fixedly connected to the top of the surface of the rotating rod 12 to facilitate stirring of the gallnut at the bottom of the inner cavity of the housing 1 and increase the extraction effect. A discharge pipe 16 is connected to the bottom of the housing 1. A valve 20 is fixedly installed on the upper part of the discharge pipe 16. An automatic adjustment device 100 is provided at the lower part of the discharge pipe 16. The four corners of the bottom of the housing 1 are fixed. The system includes a connecting rod 21, with a filter box 17 fixedly connected to its bottom. The filter box 17 contains an automatic cleaning filter. The bottom of the discharge pipe 16 extends to the top of the filter box 17's inner cavity. A liquid pump 27 is fixedly connected to the rear of the filter box 17, with its inlet pipe extending to the bottom of the filter box 17's inner cavity. An ultrafiltration membrane 26 is fixedly connected to the rear of the filter box. The outlet of the liquid pump 27 is connected to the inlet of the ultrafiltration membrane 26 via a pipe. A controller is fixedly installed on the right side of the filter box 17, and its output is electrically connected to the input of the motor 11. The system also includes a drying chamber and a fluidized bed. The outlet of the ultrafiltration membrane is connected to the inlet of the drying chamber via a pipe. A powder outlet is located at the bottom of the drying chamber, connected to the inlet of the fluidized bed. A base 2 is provided at the bottom of the filter box 17 to ensure stable placement of the equipment.

[0019] like Figure 2The diagram illustrates the specific structure of the automatic adjustment device 100 installed inside the discharge pipe 16. The automatic adjustment device 100 includes a first conical sleeve 110 and a second conical sleeve 120. The first conical sleeve 110 slidably extends into the second conical sleeve 120. A first annular cavity is formed between the outer surface of the first conical sleeve 110 and the inner surface of the second conical sleeve 120. A second annular cavity is formed between the outer surface of the second conical sleeve 120 and the inner surface of the discharge pipe 16. The first conical sleeve 110 includes an L-shaped support portion 111 and a flexible portion 120. The upper end face of the second conical sleeve 120 and the support portion 111... A disc spring 113 is provided between the lower end faces of the two conical sleeves 110 and 120. A first channel 123 is provided on the upper part of the second conical sleeve 120 and a second channel 122 is provided on the lower part of the second conical sleeve 120. The first channel 123 connects the first annular cavity and the second annular cavity, and the second channel 122 connects the second annular cavity and the outlet of the discharge pipe 16. A diversion cone 121 is formed on the bottom inner surface of the second conical sleeve 120. The cone angle of the first conical sleeve 110 relative to the center line of the discharge pipe 16 is smaller than the cone angle of the second conical sleeve 120 relative to the center line of the discharge pipe 16, that is, the size of the first annular cavity gradually decreases from top to bottom.

[0020] The working process of the automatic adjustment device 100 is as follows: In the initial stage of valve 20 opening, the liquid level in the tank 1 is high, and the flow velocity and pressure to the automatic adjustment device 100 are relatively large. At this time, under the action of the medium impact, the upper end face of the support part 111 compresses the disc spring 113, and the first cone sleeve 110 moves downward relative to the second cone sleeve 120. Since the size of the first annular cavity gradually decreases from top to bottom, the size of the flow channel between the first cone sleeve 110 and the second cone sleeve 120 is reduced, which reduces the speed of the medium flowing to the filter box. As the liquid level in the tank 1 gradually decreases, the flow velocity and pressure to the automatic adjustment device 100 also gradually decrease. The disc spring 113 gradually returns to its original position, and the size of the flow channel between the first cone sleeve 110 and the second cone sleeve 120 gradually increases, and the speed of the medium flowing to the filter box also increases accordingly. Meanwhile, since the lower flexible part 120 of the first cone sleeve is made of elastic material, and since a flow divider cone 121 is provided on the bottom inner surface of the second cone sleeve 120, the pressure of the medium will be lost to a certain extent, resulting in different pressures on the inner and outer sides of the flexible part 112, with the pressure on the inner side being greater than that on the outer side. Under the action of the pressure difference, the flexible part 120 expands outward, further reducing the size of the first annular cavity and further reducing the speed at which the medium flows to the filter box. As the liquid level in the box 1 gradually decreases, the flow rate and pressure decrease accordingly, and the pressure loss after the medium flows through the flow divider cone 121 also decreases accordingly, reducing the pressure difference between the inner and outer sides of the flexible part 120. Under the action of its own elasticity, the flexible part 112 gradually recovers, and the speed at which the medium flows to the filter box is further increased. In summary, the automatic adjustment device 100 automatically reduces the flow area when the liquid level is high and automatically increases the flow area when the liquid level is low. This achieves the effect of minimizing the fluctuation in the velocity of the liquid flowing into the filter box under different liquid level conditions. It solves the problem that the velocity of the liquid flowing into the filter box is too fast or too slow, resulting in insufficient filtration and unstable quality of tannic acid.

[0021] To prevent excessive pressure from completely flattening the flexible part and to ensure a certain flow area, several rows of discontinuous support protrusions 125 are provided on the inner surface of the second cone sleeve 120.

[0022] The automatic cleaning filtration device inside the filter box 17 includes an upper filter screen 210, an upper pin 212, an upper stop block 211, an upper collection tank 213, an upper drain valve 215, a lower filter screen 220, a lower pin 222, a lower stop block 221, a lower collection tank 223, and a lower drain valve 225. The upper filter screen 210 is rotatably connected to the inner wall of the filter box 17 via the upper pin 212. A coil spring (not shown in the figure) is fitted on the upper pin 212, causing the upper filter screen 210 to abut against the upper stop block 211. An upper collection tank 213 is located below the end of the upper filter screen away from the upper pin 212. An upper drain valve 215 is installed on the pipe connecting the upper collection tank to the outside to control the discharge of wastewater. A lower filter screen 220 is located below the upper filter screen 210 and is rotatably connected to the filter box 17 via the lower pin 222. On the inner wall of 7, a coil spring (not shown in the figure) is sleeved on the lower pin 212. The coil spring causes the lower filter screen 220 to abut against the lower stop block 221. A lower collection trough 223 is provided below the end of the lower filter screen away from the upper pin 222. A lower drain valve 225 is provided on the pipe connecting the lower collection trough to the outside to control the discharge of sewage. An interlocking device is provided between the upper filter screen and the lower filter screen. The interlocking device includes an upper magnetic block 232 fixed on the lower surface of the upper filter screen 210 and a lower magnetic block 233 provided on the upper surface of the lower filter screen. The upper magnetic block 232 is connected to the upper filter screen through a connecting rod 231. The upper magnetic block 232 and the lower magnetic block 233 are arranged to attract each other. A return water component with a triangular cross section is provided below the upper filter screen and the length of the return water component extending inward is greater than the length of the upper collection trough and the lower collection trough extending inward.

[0023] The upper surfaces of both the upper and lower baffles are inclined to prevent impurities from accumulating on their upper surfaces.

[0024] The automatic cleaning filtration device in filter box 17 operates as follows: the mixed medium flowing from discharge pipe 16 to filter box 17 passes through the upper filter screen and the lower filter screen for filtration. Since the mixed medium passes through the upper filter screen first, more impurities accumulate on the upper filter screen surface first. As the amount of impurities increases, the weight on the upper filter screen gradually increases, and the increased amount of impurities also clogs more filter holes on the upper filter screen. The resistance of the medium on the upper filter screen also gradually increases. When the spring force on the upper pin 212 can no longer support the weight and resistance of the impurities on the upper filter screen, the upper filter screen will tilt and open, allowing the impurities accumulated on the upper filter screen surface to slide into the upper collection groove 213. With reduced impurities and resistance, the upper filter screen automatically cleans itself under the action of a torsion spring. The lower filter screen is similarly configured to achieve the same online automatic cleaning process, preventing equipment shutdown due to impurity accumulation. To prevent a large leakage of impurities caused by the simultaneous opening of the upper and lower filters, an interlocking device is installed between them. When the upper filter screen tilts downward to open, the upper magnetic block 232 fixed on the lower surface of the upper filter screen 210 moves downward accordingly. The attraction between the upper magnetic block 232 and the lower magnetic block 233 increases, preventing the lower filter screen from falling. This ensures that the lower and upper filters do not open simultaneously, improving the reliability of the filtration device. The triangular cross-section return water components installed below both the upper and lower filter screens can cause turbulence and backflow of the media in the upper and lower filter screens. The upward backflow of the media can help the opened upper and lower filter screens to quickly abut against the upper baffle 211 and the lower baffle, solving the problem that the filter plates cannot be closed in time by spring force alone after opening. At the same time, the backflow of the media can also help the impurities on the filter screen to better detach from the filter screen and slide into the collection tank.

[0025] In use, the motor 11 is started by the controller, gallnut powder is added through the feed pipe 10, and water is added through the water inlet pipe 5. The output shaft of the motor 11 drives the rotating rod 12 to rotate, and the rotating rod 12 drives the blade 13 to rotate and stir, thus extracting the gallnut. During the extraction process, the stirring rack 15 stirs the gallnut to increase the extraction effect. After the extraction is completed, the valve 20 is opened so that the medium can flow stably to the filter box 17 through the automatic adjustment device 100. The automatic cleaning in the filter box 17 can reliably filter the gallnut waste. The liquid pump 27 draws the filtered liquid and discharges it into the ultrafiltration membrane 26. The ultrafiltration membrane 26 filters the fine residue in the extract to obtain tannic acid purified solution, thus realizing the extraction and purification of gallnut tannic acid. The tannic acid purified solution is added to the drying oven to dry it into tannic acid powder. The enteric coating material and tannic acid powder are added to the fluidized bed to obtain coated tannic acid as a feed additive.
