Description

Technical Field

[0001] The utility model relates to the technical field of enteral nutrition preparation production, in particular to a filtering device for enteral nutrition preparation production. Background Art

[0002] Enteral nutrition preparations are a type of nutritional support provided through tube feeding to patients who are unable or unwilling to take nutrition through normal oral intake. Such preparations are usually made of a mixture of carbohydrates, fats, proteins, vitamins and minerals. In the production process of enteral nutrition preparations, the filtration device is a key equipment to ensure the safety and quality of the final product;

[0003] Traditional filtration equipment for enteral nutrition preparation production typically uses multiple layers of filter screens bolted together within a filter barrel. Each filter screen layer has different functions and characteristics, typically including coarse and fine filters for filtering impurities and microorganisms of varying sizes. The preparation enters the filter barrel by free fall and passes through the filter screens layer by layer, starting from the top.

[0004] Traditional filtration devices for the production of enteral nutrition preparations have the following problems: Since the flow of liquid during free-fall filtration mainly depends on gravity, it can lead to uneven liquid distribution, especially in the case of multi-layer filter screens. This may cause some filters to be overloaded while other parts are not fully utilized, thereby reducing the overall filtration efficiency. In addition, the multi-layer filter screens are fixed and installed by bolts, which increases the complexity and time-consuming maintenance process when replacement or maintenance is required. For this reason, we propose a filtration device for the production of enteral nutrition preparations. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a filtering device for the production of enteral nutrition preparations, which can ensure that the enteral nutrition preparations are evenly distributed on each layer of the filter screen and accurately control their contact time and position. At the same time, the filter screen can be quickly replaced and maintained, thereby improving the overall efficiency and operational convenience of the enteral nutrition preparation production process, and can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned object, the present utility model provides the following technical solutions: a filtering device for producing enteral nutrition preparations, comprising a first mounting plate, a shaking mechanism, and a mounting seat;

[0007] First mounting plate: a U-shaped seat 1 is fixedly connected to the middle of its upper surface, a fixed block is rotatably connected to the interior of the U-shaped seat 1 through a pin shaft, a filter barrel is fixedly connected to the top of the fixed block, and a sealing cover is clamped at the feed port on the top of the filter barrel;

[0008] Rocking mechanism: It is arranged on the left side of the first mounting plate, and the right end of the rocking mechanism extends to the outside of the right side of the first mounting plate, and the right end of the rocking mechanism is mounted in conjunction with the left end of the outer surface of the filter barrel;

[0009] Mounting seats: There are three of them, which are fixedly connected to the inner wall of the filter barrel respectively. The upper surface of the mounting seats is provided with mounting grooves, and the inner walls of the mounting grooves are installed with filters through mounting mechanisms, which can ensure that the enteral nutrition preparations are evenly distributed on each layer of the filter and accurately control their contact time and position. At the same time, the filters can be quickly replaced and maintained, thereby improving the overall efficiency and operational convenience of the enteral nutrition preparation production process.

[0010] Furthermore, it also includes a single-chip microcomputer, which is arranged at the front end of the upper surface of the first mounting plate, and the input end of the single-chip microcomputer is electrically connected to the external power supply to facilitate the regulation of the operation of the electrical appliance.

[0011] Furthermore, it also includes a discharge pipe, which is fixedly connected to the lower end of the filter barrel, and a valve is connected in series in the middle of the discharge pipe to facilitate the delivery of the enteral nutrition preparation to the required container or system.

[0012] Furthermore, the rocking mechanism includes a rotating shaft, a second mounting plate, a roller, a rotating shaft, a connecting plate and a limiting groove. The second mounting plate is fixedly connected to the left end of the outer surface of the filter barrel, and a limiting groove is provided on the left side of the second mounting plate. The rotating shaft is rotatably connected to the upper end of the right side surface of the first mounting plate. The right end of the rotating shaft is fixedly connected to the connecting plate. The eccentric part of the connecting plate is rotatably connected to the rotating shaft. The right end of the rotating shaft is rotatably connected to the roller. The roller is located inside the limiting groove, so that the filter barrel as a whole produces a back and forth rocking motion.

[0013] Furthermore, the shaking mechanism also includes a motor, which is installed on the left side of the first mounting plate by bolts. The right end of the motor's output shaft is fixedly connected to the left end of the rotating shaft. The input end of the motor is electrically connected to the output end of the microcontroller to drive the shaking mechanism to operate.

[0014] Furthermore, the mounting mechanism includes an extrusion block and a U-shaped seat 2, the U-shaped seat 2 is fixedly connected to the upper surface of the mounting seat, the interior of the U-shaped seat 2 is rotatably connected to the extrusion block through a pin shaft, and the bottom end of the extrusion block is installed in cooperation with the filter screen in the vertically adjacent mounting groove, and the filter screen can be installed without using tools or tightening bolts.

[0015] Furthermore, the mounting mechanism also includes an arc-shaped sliding hole, an arc-shaped sliding column and a spring. The arc-shaped sliding holes are all opened on the upper surface of the mounting seat. The inner walls of the arc-shaped sliding holes are slidably connected with the arc-shaped sliding columns. The top ends of the arc-shaped sliding columns are fixedly connected to the lower surfaces of the vertically adjacent extrusion blocks. The lower surface of the extrusion block and the upper surface of the mounting seat on the same horizontal plane are fixedly connected with springs. The springs are all sleeved on the outer surface of the arc-shaped sliding columns to bear the pressure and stability between the extrusion block and the filter.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the filter device for producing enteral nutrition preparations has the following advantages:

[0017] 1. Pour the enteral nutrition preparation to be filtered into the filter barrel. The enteral nutrition preparation enters the upper filter screen from the top and the initial filtration begins. Then the single-chip microcomputer controls the operation of the motor. The output shaft of the motor rotates to drive the rotating shaft. The rotating shaft drives the rotating shaft at the eccentric position to start rotating through the connecting plate. The rotating shaft is centered on the rotating shaft and drives the roller to rotate and slide in the limit groove. As the angle of rotation of the roller changes, the fixed block on the filter barrel and the pin shaft in the U-shaped seat also rotate synchronously, causing the filter barrel as a whole to swing back and forth, thereby ensuring that the enteral nutrition preparation is evenly distributed on each layer of the filter screen, increasing the contact time and position of the enteral nutrition preparation on the filter screen, and helping to efficiently remove particles or impurities of different sizes and types, thereby improving the accuracy and efficiency of the filtration device used in the production of enteral nutrition preparations.

[0018] 2. After the filter has been used for a period of time, more impurities will accumulate on the surface, affecting the filtering effect. At this time, open the cover on the filter barrel and bend the extrusion block, which will cause the extrusion block to start rotating around the pin shaft in the U-shaped seat 2. The rotation of the extrusion block will also drive the arc-shaped slide column to move in the arc-shaped slide hole. At this time, the spring will be stretched. The stretching process of the spring makes the extrusion block and the adjacent filter screen no longer squeezed together, and the filter screen can move freely. The filter screen can be removed from the installation slot and replaced with a new one. After installing the new filter screen, release the extrusion block, and the rebound force of the spring will make the extrusion block contact with the upper surface of the filter screen again, restoring the extrusion state, ensuring that the newly installed filter screen can be effectively fixed in the installation slot for subsequent filtering operations, thereby allowing faster filter replacement and maintenance without the use of tools or tightening bolts, saving operation time and labor costs, and significantly improving the efficiency of the filtration device for the production of enteral nutrition preparations.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-4 , this embodiment provides a technical solution: a filtering device for the production of enteral nutrition preparations, comprising a first mounting plate 2, a shaking mechanism 3 and a mounting seat 10;

[0026] The first mounting plate 2: a U-shaped seat 8 is fixedly connected to the middle of its upper surface, and a fixing block 9 is rotatably connected to the interior of the U-shaped seat 8 via a pin shaft. The top of the fixing block 9 is fixedly connected to the filter barrel 1, and a sealing cover 4 is clamped at the feed port on the top of the filter barrel 1. It also includes a single-chip microcomputer 7, which is arranged at the front end of the upper surface of the first mounting plate 2. The input end of the single-chip microcomputer 7 is electrically connected to an external power supply. It also includes a discharge pipe 6, which is fixedly connected to the lower end of the filter barrel 1. A valve 5 is connected in series in the middle of the discharge pipe 6. When the valve 5 connected in series in the middle of the discharge pipe 6 is opened, the enteral nutrition preparation is discharged to the outside in sequence and delivered to the required container or system;

[0027] The rocking mechanism 3 is arranged on the left side of the first mounting plate 2, and the right end of the rocking mechanism 3 extends to the outside of the right side of the first mounting plate 2. The right end of the rocking mechanism 3 is mounted in cooperation with the left end of the outer surface of the filter barrel 1. The rocking mechanism 3 includes a rotating shaft 32, a second mounting plate 33, a roller 34, a rotating shaft 35, a connecting plate 36 and a limiting groove 37. The second mounting plate 33 is fixedly connected to the left end of the outer surface of the filter barrel 1. The left side of the second mounting plate 33 is provided with a limiting groove 37. The rotating shaft 32 is rotatably connected to the upper end of the right side of the first mounting plate 2. The right end of the rotating shaft 32 is fixedly connected to the connecting plate 36. The eccentric part of the connecting plate 36 is rotatably connected to the rotating shaft 35. The right end of the rotating shaft 35 is rotatably connected to the roller 34. The roller 34 is located in the limiting groove 3 Inside 7, the rocking mechanism 3 also includes a motor 31, which is mounted on the left side of the first mounting plate 2 by bolts. The right end of the output shaft of the motor 31 is fixedly connected to the left end of the rotating shaft 32. The input end of the motor 31 is electrically connected to the output end of the single-chip microcomputer 7. The operation of the motor 31 is regulated by the single-chip microcomputer 7. The rotation of the output shaft of the motor 31 drives the rotating shaft 32 to operate. The rotating shaft 32 drives the eccentric rotating shaft 35 to start rotating through the connecting plate 36. The rotating shaft 35 is centered on the rotating shaft 32 and drives the roller 34 to rotate and slide in the limiting groove 37. As the angle of rotation of the roller 34 changes, the fixed block 9 on the filter barrel 1 and the pin shaft in the U-shaped seat 8 also rotate synchronously, so that the filter barrel 1 as a whole produces a back and forth rocking motion;

[0028] Mounting seats 10: There are three of them, and the three mounting seats 10 are fixedly connected to the inner wall of the filter barrel 1 respectively. The upper surface of the mounting seat 10 is provided with a mounting groove 13. The inner wall of the mounting groove 13 is installed with a filter screen 12 through a mounting mechanism 11. The upper filter screen 12 is specifically a glass fiber filter paper, which is used for primary filtration to remove larger particles. The middle filter screen 12 is specifically a polyamide membrane filter membrane, which is used for further filtration to improve the filtration accuracy. The lower filter screen 12 is specifically a polytetrafluoroethylene membrane filter screen, which serves as the final filter layer to ensure the purity of the product. The enteral nutrition preparation to be filtered is poured into the filter barrel 1, and the enteral nutrition preparation enters the upper filter screen 12 from the top. The preliminary filtration begins. Under the action of shaking, larger particles or impurities pass through the upper filter screen in turn. 12 is filtered out, and the finer particles or liquid part enters the middle filter screen 12 through the filter screen. The material entering the middle filter screen 12 is filtered again, and the finer particles are separated to the filter screen 12 at the lower end. The cleaner enteral nutrition preparation is finally filtered through the filter screen 12 at the lower end to remove the remaining tiny particles or impurities, making the enteral nutrition preparation cleaner and purer. After multiple filtrations, the cleaner enteral nutrition preparation flows from the lower filter screen 12 to the discharge pipe 6. The mounting mechanism 11 includes an extrusion block 114 and a U-shaped seat 115. The U-shaped seat 115 is fixedly connected to the upper surface of the mounting seat 10. The interior of the U-shaped seat 115 is rotatably connected to the extrusion block 114 through a pin shaft. The bottom end of the extrusion block 114 is connected to the vertically adjacent mounting The filter screen 12 in the mounting groove 13 is installed in cooperation, and the mounting mechanism 11 also includes an arc-shaped sliding hole 111, an arc-shaped sliding column 112 and a spring 113. The arc-shaped sliding hole 111 is opened on the upper surface of the mounting seat 10, and the inner wall of the arc-shaped sliding hole 111 is slidably connected with the arc-shaped sliding column 112. The top of the arc-shaped sliding column 112 is fixedly connected to the lower surface of the vertically adjacent extrusion block 114. The lower surface of the extrusion block 114 is fixedly connected to the upper surface of the mounting seat 10 on the same horizontal plane with a spring 113. The spring 113 is sleeved on the outer surface of the arc-shaped sliding column 112. When the filter screen 12 is used for a period of time, more impurities will accumulate on the surface, affecting the filtering effect. At this time, open the cover 4 on the filter barrel 1 and pry the extrusion block 114, which will make the extrusion block 114 The pin shaft in the U-shaped seat 115 starts to rotate, and the rotation of the extrusion block 114 drives the arc-shaped slide column 112 to move in the arc-shaped slide hole 111. At this time, the spring 113 will be stretched. The stretching process of the spring 113 makes the extrusion block 114 and the adjacent filter screen 12 no longer squeezed together, and the filter screen 12 can move freely. The filter screen 12 is taken out of the installation slot 13 and replaced with a new filter screen 12. After installing the new filter screen 12, the extrusion block 114 is released, and the rebound force of the spring 113 makes the extrusion block 114 contact the upper surface of the filter screen 12 again, restoring the extrusion state, ensuring that the newly installed filter screen 12 can be effectively fixed in the installation slot 13 for subsequent filtering operations, thereby allowing for faster replacement and maintenance of the filter screen.No tools or bolts need to be tightened, saving operation time and labor costs, significantly improving the efficiency of the filtration device used in the production of enteral nutrition preparations.

[0029] The working principle of the filter device for the production of enteral nutrition preparations provided by the present invention is as follows: first, the enteral nutrition preparation to be filtered is poured into the filter barrel 1, and the enteral nutrition preparation enters the filter screen 12 at the upper end from the top, and the preliminary filtration begins. Then, the single-chip microcomputer 7 controls the operation of the motor 31, and the output shaft of the motor 31 rotates to drive the rotating shaft 32 to operate. The rotating shaft 32 drives the eccentric rotating shaft 35 to start rotating through the connecting plate 36. The rotating shaft 35 takes the rotating shaft 32 as the center and drives the roller 34 to rotate and slide in the limiting groove 37. As the angle of the roller 34 rotates, the fixed block on the filter barrel 1 is rotated. 9 and the pin shaft in the U-shaped seat 8 also rotate synchronously, causing the filter barrel 1 to swing back and forth as a whole. Under the shaking action, larger particles or impurities are filtered out through the upper filter screen 12 in turn, and smaller particles or liquids pass through the filter screen into the middle filter screen 12. The materials entering the middle filter screen 12 are filtered again, and the smaller particles are separated into the lower filter screen 12. The cleaner enteral nutrition preparation is finally filtered through the lower filter screen 12 to remove the remaining tiny particles or impurities, making the enteral nutrition preparation cleaner and purer. After multiple filtrations, the cleaner enteral nutrition preparation is discharged from the lower filter screen 12. The filter screen 12 flows to the discharge pipe 6, and then the valve 5 connected in series in the middle of the discharge pipe 6 is opened to discharge the outside in turn, and the enteral nutrition preparation is delivered to the required container or system. After the filter screen 12 has been used for a period of time, more impurities will accumulate on the surface, affecting the filtering effect. At this time, the cover 4 on the filter barrel 1 is opened, and the extrusion block 114 is moved, which will cause the extrusion block 114 to start rotating around the pin shaft in the U-shaped seat 115. The rotation of the extrusion block 114 also drives the arc-shaped slide column 112 to move in the arc-shaped slide hole 111. At this time, the spring 113 will be stretched, and the stretching process of the spring 113 causes the extrusion block 114 to move with the adjacent filter screen 1 2 is no longer squeezed together, and the filter screen 12 can move freely. The filter screen 12 is taken out of the installation groove 13 and replaced with a new filter screen 12. After the new filter screen 12 is installed, the squeezing block 114 is released. The rebound force of the spring 113 will make the squeezing block 114 contact the upper surface of the filter screen 12 again, and the squeezing state is restored, ensuring that the newly installed filter screen 12 can be effectively fixed in the installation groove 13 for subsequent filtering operations. This allows for faster replacement and maintenance of the filter screen without the need to use tools or tighten bolts, saving operation time and labor costs, and significantly improving the efficiency of the filtration device for the production of enteral nutrition preparations.
