Description

Technical Field

[0001] This application relates to the technical field of filtration equipment, and in particular to a low-loss filtration device for nutritional oral liquids. Background Art

[0002] Nutritional oral liquid is a nutritional supplement provided in liquid form, usually containing nutrients such as vitamins, minerals, amino acids, plant extracts, etc., aiming to provide additional nutritional support for the human body.

[0003] In the current nutritional oral liquid production technology, after various nutrients and pure water are fully mixed and stirred, the filter residue is filtered out, and the final obtained liquid is the nutritional oral liquid. Among them, the filtration link is a key step to ensure product quality. In high-clarity oral liquids, the distribution of nutritional components is more uniform, which helps to improve the absorption efficiency of nutritional components by the human body and ensure the health benefits of nutritional products; moreover, the clarified oral liquid has a clearer and more transparent appearance, which can enhance the attractiveness of the product and the acceptance of consumers; at the same time, the clarification process can reduce the impact of suspended substances on the taste, making the oral liquid smoother and easier to swallow. When the clarity of the oral liquid is higher, the possibility of microbial growth in the oral liquid is lower, which not only reduces the risk of product spoilage, but also can extend the shelf life of the oral liquid, thereby improving the stability and safety of the product during the shelf life.

[0004] In the prior art, usually after various nutrients and pure water are fully mixed and stirred, precipitation and filtration are carried out to separate the particulate matter and impurities in the solution from the solution. Common filtration methods include plate and cloth interception filtration, sand filter rod microporous filtration, centrifugal separation, and diatomaceous earth adsorption filtration, etc. Although these methods can remove impurities, in the continuous production process of nutritional oral liquids, the filtration efficiency often decreases due to filter material blockage or wear. In order to ensure the filtration accuracy in production, it is necessary to frequently stop the equipment for cleaning or replacing the filter material, and replacing the filter material during the production process is extremely likely to cause product loss, thus greatly reducing the product yield and production efficiency. Utility Model Content

[0005] In order to improve the product yield and production efficiency of nutritional oral liquid filtration production, this application provides a low-loss filtration device for nutritional oral liquids.

[0006] The low-loss filtration device for nutritional oral liquids provided by this application adopts the following technical solutions:

[0007] A low-loss filtration device for nutritional oral liquid, comprising a liquid preparation tank and a filter. The filter includes a tank body, a tank cover, and a mesh frame disposed inside the tank body. The mesh frame divides the tank body vertically into two chambers, and the two chambers are communicated through the mesh holes on the mesh frame. An inlet is communicated with the side wall of the upper chamber inside the tank body, and a liquid inlet pipe is connected between the inlet and the liquid outlet end at the bottom of the liquid preparation tank. An outlet is communicated with the bottom of the lower chamber inside the tank body, and a liquid outlet pipe is connected between the outlet and the liquid inlet end at the top of the liquid preparation tank. Solenoid valves are connected in series on both the liquid inlet pipe and the liquid outlet pipe.

[0008] By adopting the above technical solution, during the continuous production process of nutritional oral liquid, a closed system is formed between the liquid preparation tank and the filter through the liquid inlet and outlet pipes. Driven by a precisely controlled pressure difference, the original liquid of the oral liquid flows out from the bottom of the liquid preparation tank when various nutrients are stirred and mixed in the preparation tank, enters the upper chamber of the filter through the liquid inlet pipe, then filters through the mesh holes on the mesh frame and enters the lower chamber, and finally returns to the top of the liquid preparation tank through the liquid outlet pipe. Through cyclic filtration, while continuously improving the clarity of the nutritional oral liquid, the nutritional components in the nutrients are also evenly dispersed into the solution of the oral liquid as much as possible. When the filter material needs to be replaced during the continuous production process of nutritional oral liquid, the solenoid valve can be closed to stop the liquid from flowing to the filter, so that the stirring work in the liquid preparation tank can still continue, and then the mesh frame can be replaced, avoiding the disadvantages of the traditional filtration method that requires shutdown to replace the filter material, not only reducing the loss during the production process, but also improving the stability and production efficiency of the filtration process.

[0009] Optionally, a lap joint ring with an L-shaped cross-section is provided on the inner ring side wall of the tank body. The mesh frame is made of stainless steel, and a positioning ring inserted and matched with the lap joint ring is provided at the top end of the mesh frame.

[0010] By adopting the above technical solution, the mesh frame can be quickly installed by simply inserting the positioning ring into the lap joint ring. It not only simplifies the installation process but also improves the stability of the mesh frame.

[0011] Optionally, a filter bag fitting the inner wall of the mesh frame is detachably provided inside the tank body. A top support protrusion is coaxially provided on the bottom wall of the inner circle of the positioning ring, and an installation ring made of latex material is coaxially provided at the top end of the filter bag. When the installation ring is inserted into the positioning ring, the installation ring abuts against the top support protrusion.

[0012] By adopting the above technical solution, according to the filtration requirements, the filter bag can be selected and installed as needed to further improve the filtration effect. When the installation ring is inserted into the positioning ring, it will be abutted by the top support protrusion, thus realizing the stable fixation of the filter bag and also facilitating the replacement of the filter bag.

[0013] Optionally, a plurality of anti-slip ridges are circumferentially distributed on the outer peripheral side wall of the mounting ring, and the plurality of anti-slip ridges are in contact with the inner side wall of the mounting ring.

[0014] By adopting the above technical solution, the anti-slip ridges can enhance the stability of the filter bag after installation, prevent it from slipping during use, and further improve the stability and reliability of the filtering device.

[0015] Optionally, two clamping blocks are circumferentially distributed on the side wall of the tank body near the upper side of the overlapping ring. A clamping groove is formed on the side wall of each clamping block. The two clamping blocks are centrosymmetrically arranged along the axial direction of the tank body. A limiting ring is arranged in the tank body. The limiting ring is used to jointly limit the mesh frame and the filter bag in the overlapping ring. Corresponding to each clamping groove, a plugging rod is arranged on the outer side wall of the limiting ring. A single plugging rod is in clamping fit with a single clamping groove, and the limiting ring is jointly pressed against the top walls of the overlapping ring, the positioning ring and the mounting ring, and the limiting ring is rotated to make the plugging rod clamped in the corresponding clamping groove.

[0016] By adopting the above technical solution, the limiting ring can effectively limit the mesh frame and the filter bag, prevent them from shifting or falling off during the filtering process, not only improve the stability of the filtering device, but also provide convenience for the disassembly and installation of the mesh frame and the filter bag.

[0017] Optionally, flow meters are serially arranged on the liquid inlet and outlet pipes on the side close to the tank body of the corresponding solenoid valves. An alarm is arranged on the tank cover. The flow meters are electrically connected to the alarm. When the flow difference between the two flow meters reaches a certain value, the flow meters transmit electrical signals to the alarm, and the alarm emits a warning sound.

[0018] By adopting the above technical solution, the combination of the flow meters and the alarm can monitor the liquid inlet and outlet flow rates in real time. When the flow difference between the two flow meters reaches a certain value, it means that the mesh holes of the mesh frame or the filter bag are blocked by solid impurities and reach the bottom where it is difficult to continue the good filtering work. At this time, the alarm emits an alarm in time to remind the operator to replace the mesh frame or the filter bag in time to ensure the smooth progress of the production process.

[0019] Optionally, a pressure gauge is connected to the chamber above the tank body on the tank cover, and the pressure gauge is electrically connected to the alarm.

[0020] By adopting the above technical solution, the pressure gauge can monitor the pressure change in the chamber in real time and trigger the alarm to emit a warning sound when the pressure is abnormal, thereby ensuring the safety of the production process.

[0021] Optionally, a liquid suction pipe is arranged in parallel at a position of the liquid outlet pipe close to the liquid outlet, and a liquid suction pump is arranged in the liquid suction pipe. When it is necessary to replace the filter bag in the filter, the liquid suction pump is started to suck the accumulated liquid in the tank.

[0022] By adopting the above technical solution, the addition of the liquid suction pipe and the liquid suction pump can quickly suck the accumulated liquid in the tank when it is necessary to replace the filter bag in the filter, thereby reducing the product loss during the replacement process.

[0023] Optionally, a sampling inspection pipe is arranged in parallel at a position of the liquid inlet pipe close to the liquid outlet end of the liquid preparation tank, and a manual valve is arranged at the liquid outlet end of the sampling inspection pipe.

[0024] By adopting the above technical solution, the combined design of the sampling inspection pipe and the manual valve facilitates sampling inspection at any time during the production process to ensure that the product quality meets the standard requirements.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. During the continuous production process of the nutritional oral liquid, a closed system is formed between the liquid preparation tank and the filter through the liquid inlet and outlet pipes. Driven by the precisely controlled pressure difference, the original liquid of the oral liquid flows out from the bottom of the liquid preparation tank when various nutrients are stirred and mixed in the batching tank, enters the upper chamber of the filter through the liquid inlet pipe, then filters through the mesh holes on the mesh frame into the lower chamber, and finally returns to the top of the liquid preparation tank through the liquid outlet pipe. Through cyclic filtration, while continuously improving the clarity of the nutritional oral liquid, the nutritional components in the nutrients are also evenly dispersed into the oral liquid solution as much as possible. When it is necessary to replace the filter medium during the continuous production process of the nutritional oral liquid, the solenoid valve can be closed to stop the liquid from flowing to the filter, so that the stirring work in the liquid preparation tank still continues, and then the mesh frame can be replaced, avoiding the disadvantages of the traditional filtration method that requires shutdown to replace the filter medium, not only reducing the loss during the production process, but also improving the stability and production efficiency of the filtration process;

[0027] 2. The quick installation of the mesh frame can be realized only by inserting the positioning ring into the overlapping ring. This not only simplifies the installation process but also improves the stability of the mesh frame;

[0028] 3. According to the filtration requirements, selecting and installing the filter bag as needed further improves the filtration effect. When the installation ring is inserted into the positioning ring, it will be abutted by the top support protrusion, thereby realizing the stable fixation of the filter bag and also facilitating the replacement of the filter bag.

[0035] The embodiment of the present application discloses a low-loss filtering device for nutritional oral liquid.

The filter 2 is the core component, including a tank body 21, a tank cover 22, and a filter element 23 inside the tank body 21. The filter element 23 divides the tank body 21 into two chambers vertically. A liquid inlet 211 is fixedly connected and communicated with the side wall of the upper chamber inside the tank cover 22. An inlet pipe 3 is connected between the liquid inlet 211 and the liquid outlet end at the bottom of the liquid preparation tank 1; a liquid outlet 212 is fixedly connected and communicated with the bottom of the lower chamber inside the tank body 21. An outlet pipe 4 is connected between the liquid outlet 212 and the liquid inlet end at the top of the liquid preparation tank 1.

[0037] Referring to Figure 1 and Figure 2 , during the continuous production process of nutritional oral liquid, when the oral liquid stock solution is stirred and mixed, it flows out from the bottom of the liquid preparation tank 1, enters the upper chamber of the filter 2 through the inlet pipe 3, then passes through the filtration of the filter element 23, the clear liquid flows into the lower chamber, and finally returns to the top of the liquid preparation tank 1 through the liquid outlet 212 and the outlet pipe 4.

[0038] Referring to Figure 2 and Figure 3The inner ring side wall of the tank body 21 is integrally formed with a lap ring 5 having an L-shaped cross section. The filter element 23 in this embodiment includes a mesh frame 231 and a filter bag 232. The mesh frame 231 is made of stainless steel, and a positioning ring 2311 is integrally formed on the top of the mesh frame 231 to be plugged and matched with the lap ring 5. A top support protrusion 2312 is coaxially integrally formed on the bottom wall of the inner ring of the positioning ring 2311. The filter bag 232 is arranged in contact with the inner wall of the mesh frame 231, and a mounting ring 2321 made of latex material is coaxially arranged on the top of the filter bag 232. A plurality of anti-slip ridges 2322 are fixedly distributed along the circumferential direction on the outer peripheral side wall of the mounting ring 2321.

[0039] Reference Figure 2 and Figure 3 When the filter bag 232 is inserted and installed in the mesh frame 231 , the installation ring 2321 is inserted in the positioning ring 2311 . At this time, the installation ring 2321 abuts against the top support protrusion 2312 , and the anti-slip ridge 2322 abuts against the inner side wall of the installation ring 2321 .

[0040] Reference Figure 2 and Figure 3 In order to prevent the mesh frame 231 and the filter bag 232 from shifting or falling off during the filtering process, a limiting ring 6 is provided in the tank body 21 for limiting the mesh frame 231 and the filter bag 232 in the lap ring 5. Two clamping blocks 213 are fixedly distributed along the circumferential direction on the side wall of the tank body 21 near the top of the lap ring 5. A clamping groove 2131 is provided on the side wall of each clamping block 213, and the two clamping blocks 213 are centrally symmetrically arranged along the axial direction of the tank body 21. A plug-in rod 61 is fixedly provided on the outer side wall of the limiting ring 6 corresponding to each clamping groove 2131, and a single plug-in rod 61 is clamped and matched with a single clamping groove 2131.

[0041] Reference Figure 2 and Figure 3 , press the limiting ring 6 against the top wall of the lap ring 5, the positioning ring 2311 and the mounting ring 2321, and rotate the limiting ring 6, so that the plug-in rod 61 can be clamped in the corresponding clamping groove 2131, thereby realizing effective positioning of the net frame 231 and the filter bag 232.

[0042] Reference Figure 1 In order to improve the safety of continuous production of nutrient oral liquid, electromagnetic valves 31 and flow meters 32 are arranged in series on the inlet and outlet pipes 4. The flow meters 32 are located on the side of the corresponding electromagnetic valves 31 close to the tank body 21 on the inlet and outlet pipes 4. A pressure gauge 221 and an alarm 222 are fixedly arranged on the top wall of the tank cover 22. The pressure gauge 221 is connected to the upper chamber in the tank body 21, and the flow meter 32 and the pressure gauge 221 are electrically connected to the alarm 222.

[0043] Reference Figure 1 and Figure 2, in order to reduce product loss during the replacement process, a liquid extraction pipe 7 is arranged in parallel at a position of the liquid outlet pipe 4 close to the liquid outlet 212, and a liquid extraction pump 71 is fixedly connected and arranged inside the liquid extraction pipe 7. When the filter bag 232 inside the filter 2 needs to be replaced, the liquid extraction pump 71 can quickly extract the accumulated liquid in the tank body 21.

[0044] Referring to Figure 1 , in order to facilitate sampling inspection at any time during the production process, a sampling inspection pipe 8 is arranged in parallel at a position of the liquid inlet pipe 3 close to the liquid outlet end of the liquid preparation tank 1, and a manual valve 81 is fixedly connected and arranged at the liquid outlet end of the sampling inspection pipe 8.

[0045] The implementation principle of a low-loss filtering device for nutritional oral liquid in an embodiment of the present application is as follows: During the continuous production process of nutritional oral liquid, a closed system is formed between the liquid preparation tank 1 and the filter 2 through the inlet and outlet pipes 4. Driven by a precisely controlled pressure difference, the original liquid of the oral liquid flows out from the bottom of the liquid preparation tank 1 when various nutrients are stirred and mixed in the batching tank, enters the upper chamber of the filter 2 through the liquid inlet pipe 3, then filters through the mesh holes on the mesh frame 231 and enters the lower chamber, and finally flows back to the top of the liquid preparation tank 1 through the liquid outlet pipe 4.

[0046] During the continuous production process, by simply controlling the on-off state of the solenoid valve 31 according to the set program, automatic filtration of the oral liquid can be achieved. At the same time, by real-time monitoring the data changes of the flow meter 32 and the pressure gauge 221, abnormal situations during the filtration process can be detected and processed in a timely manner to ensure the smooth progress of the production process. When the mesh frame 231 or the filter bag 232 needs to be replaced, just close the corresponding valve, start the liquid extraction pump 71 to suck out the accumulated liquid in the tank body 21, and then the mesh frame 231 or the filter bag 232 can be easily removed and replaced.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
