Description

Technical Field

[0001] This utility model relates to the field of water-based solvent production, and in particular to a water-based solvent quantitative filling device. Background Technology

[0002] With the booming development of numerous industries such as chemicals, pharmaceuticals, and daily chemicals, the application of water-based solvents in production processes is becoming increasingly widespread. For example, in coating production, water-based coatings, due to their superior environmental performance, are gradually gaining a larger market share based on water-based solvents. In the formulation of pharmaceutical preparations, water-based solvents are also frequently used as carriers to dissolve active ingredients. These industries have extremely high requirements for the precision of water-based solvent dosage. Traditional rough estimation and manual filling methods are no longer sufficient to meet the needs of large-scale, high-precision production, thus creating an urgent need for equipment capable of accurately quantitatively filling water-based solvents.

[0003] In current industrial production applications, existing water-based solvent quantitative filling equipment has many unresolved problems. On the one hand, many devices perform poorly in the mixing stage, failing to adequately agitate the water-based solvent. This leads to solute precipitation and stratification, making it difficult to achieve uniform solvent composition in the filled product, significantly impacting the quality and performance of subsequent products. On the other hand, their filter devices often lack effective anti-clogging designs. In actual use, impurities easily clog the filters, requiring frequent and labor-intensive cleaning, severely disrupting the normal filling process, and reducing overall filling efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quantitative filling device for water-based solvents. This device solves the problems of insufficient mixing, easy clogging of the filter screen, and inability to adjust the filling height in existing quantitative filling devices for water-based solvents.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A water-based solvent quantitative filling device includes a base plate, a fixed frame fixedly connected to the top of the base plate, a stirring tank fixedly connected to the rear top of the fixed frame, a tank lid installed at the top of the stirring tank, a motor installed at the top of the tank lid, a rotating shaft fixedly connected to the drive end of the motor, several stirring plates fixedly connected to the front and rear outer walls of the rotating shaft, a sleeve fitted on the top outer wall of the rotating shaft, a cam connected to the rotating shaft via a rotating assembly, multiple fixed blocks fixedly connected to the top inner wall of the stirring tank, filter plates connected to the fixed blocks via elastic components, a mounting frame fixedly connected to the front outer wall of the fixed frame, an electric push rod installed at the top of the mounting frame, a push plate fixedly connected to the drive end of the electric push rod, a quantitative tank fixedly connected to the bottom end of the mounting frame, a connecting pipe slidably connected to the bottom inner wall of the quantitative tank, and a moving plate connected to the quantitative tank via an adjusting assembly.

[0008] Furthermore, the elastic component includes a fixed rod fixedly connected to the top of the fixed block, a first spring is provided on the inner wall of the fixed rod, a sliding rod is slidably connected to the inner wall of the fixed rod, and the bottom end of the filter plate is fixedly connected to the top end of the sliding rod.

[0009] Furthermore, the bottom end of each of the first springs is connected to the inner wall of the fixed rod, and the top end of each of the first springs is connected to the bottom end of the sliding rod.

[0010] Furthermore, the adjustment assembly includes mounting blocks fixedly connected to the left and right sides of the bottom of the metering barrel, each mounting block having a slidable insert rod on its inner wall, each mounting block having a second spring on its inner wall, and the inner wall of the moving plate being fixedly connected to the outer wall of the insert rod.

[0014] This utility model has the following beneficial effects:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a water-based solvent quantitative filling device, comprising: a base plate 1; a fixing frame 2 fixedly connected to the top of the base plate 1; a stirring tank 3 fixedly connected to the rear top of the fixing frame 2; a tank cover 4 installed on the top of the stirring tank 3; a motor 5 installed on the top of the tank cover 4; a rotating shaft 6 fixedly connected to the drive end of the motor 5; several stirring plates 7 fixedly connected to the outer walls of the front and rear sides of the rotating shaft 6; a sleeve 8 fitted onto the outer wall of the top of the rotating shaft 6; and a cam 12 connected to the rotating shaft 6 via a rotating assembly. The moving assembly includes a first bevel gear 9 fixedly connected to the top outer wall of the rotating shaft 6, a second bevel gear 10 meshing with the bottom left and right outer walls of the first bevel gear 9, a rotating rod 11 fixedly connected to the inner wall of the second bevel gear 10, the inner wall of the cam 12 fixedly connected to the outer wall of the rotating rod 11, the opposite side of the rotating rod 11 rotatably connected to the inner wall of the mixing tank 3, a connecting pipe 25 fixedly connected to the bottom of the mixing tank 3, a valve 26 installed on the outer wall of the connecting pipe 25, and the front end of the connecting pipe 25 connected to the metering tank 19.

[0027] Specifically, the base plate 1 serves as a support frame 2, stabilizing the entire equipment structure. The support frame 2 supports the mixing tank 3, positioning it for easy operation. The tank lid 4 seals the mixing tank 3, preventing internal liquid from splashing out or debris from entering. The motor 5 provides power for stirring and transmits power to the rotating shaft 6, causing it to rotate. When the rotating shaft 6 rotates, the stirring plate 7 rotates accordingly, stirring the aqueous solvent inside the mixing tank 3. The sleeve 8 protects the first bevel gear 9 and the second bevel gear 10 on the outer wall of the top of the rotating shaft 6. The rotation of the rotating shaft 6... The rotation direction of the first bevel gear 9 is changed and transmitted to the second bevel gear 10 through gear meshing. The rotation of the second bevel gear 10 is then transmitted to the rotating rod 11. When the rotating rod 11 rotates, it drives the cam 12 to rotate, thereby causing the filter screen plate 13 to vibrate to prevent the filter screen plate 13 from clogging. This allows the aqueous solvent in the mixing tank 3 to flow out through the connecting pipe 25. The flow rate and flow of the liquid in the connecting pipe 25 are controlled. The aqueous solvent in the mixing tank 3 is then transported to the metering tank 19 through the connecting pipe 25 for metering operation.

[0028] Reference Figure 3 and Figure 5 Multiple fixing blocks 14 are fixedly connected to the inner wall of the top of the mixing tank 3. The fixing blocks 14 are connected to the filter screen plate 13 through elastic components. The elastic components include fixing rods 27 fixedly connected to the top of the fixing blocks 14. The inner wall of each fixing rod 27 is provided with a first spring 16. The inner wall of each fixing rod 27 is slidably connected with a slide rod 15. The bottom end of the filter screen plate 13 is fixedly connected to the top end of the slide rod 15. The bottom end of each first spring 16 is connected to the inner wall of the fixing rod 27, and the top end of each first spring 16 is connected to the bottom end of the slide rod 15.

[0029] Specifically, the fixing block 14 provides an installation base for the elastic component and the filter plate 13. The fixing block 14 supports the fixing rod 27 to fix its position. The first spring 16 provides elastic force. The sliding rod 15 can slide within the fixing rod 27 to connect the filter plate 13 to the sliding rod 15, so that the filter plate 13 can move with the sliding rod 15. When the sliding rod 15 moves, the first spring 16 can generate elastic deformation, which plays a role in buffering and elastic support. This allows the filter plate 13 to be buffered by the elastic component when subjected to external forces such as vibration, thus better filtering impurities in the water-based solvent.

[0030] Reference Figure 1 , Figure 2 and Figure 6 A mounting bracket 28 is fixedly connected to the front outer wall of the fixed frame 2. An electric push rod 17 is mounted on the top of the mounting bracket 28. A push plate 18 is fixedly connected to the drive end of the electric push rod 17. A metering tank 19 is fixedly connected to the bottom end of the mounting bracket 28. A connecting pipe 20 is slidably connected to the inner wall of the bottom end of the metering tank 19. A moving plate 23 is connected to the metering tank 19 through an adjusting assembly. The adjusting assembly includes mounting blocks 21 fixedly connected to the left and right sides of the bottom end of the metering tank 19. The inner wall of the mounting block 21... All are slidably connected with insert rods 22. The inner wall of each mounting block 21 is provided with a second spring 24. The inner wall of each moving plate 23 is fixedly connected to the outer wall of insert rods 22. The opposite ends of the second springs 24 are connected to the inner wall of mounting block 21. The opposite ends of mounting block 21 are connected to the opposite side of moving plate 23. The outer wall of moving plate 23 is slidably connected to the inner wall of mounting block 21. Several through holes are opened on the inner walls of both sides of connecting pipe 20. The size of the through holes is adapted to insert rods 22.

[0031] Specifically, the mounting bracket 28 provides mounting support for the electric push rod 17 and the metering container 19. The electric push rod 17 provides linear drive power, which is transmitted to the push plate 18, causing it to move linearly. The electric push rod 17 pushes the push plate 18 down, thereby squeezing out the aqueous solvent inside the metering container 19. The mounting bracket 28 supports the metering container 19, fixing its position. The connecting pipe 20 can slide within the metering container 19, allowing for position adjustment of the connecting pipe 20. The mounting block 21 provides a mounting base for the adjustment assembly, and the insertion rod 22 can be inserted into the mounting block 21. The inner sliding mechanism connects the insertion rod 22 to the moving plate 23, enabling them to move synchronously. The size of the through hole is adapted to the insertion rod 22. Its function is to fix the position of the connecting pipe 20 in the metering container 19 by inserting the insertion rod 22 into different through holes, thereby adjusting the height of the connecting pipe 20 to accommodate cans of different heights. Since the elastic force of the second spring 24 is greater than the frictional force of the insertion rod 22, it ensures that the insertion rod 22 can be stably inserted into the through hole and will not move on its own due to friction, thus ensuring the stability of the position of the connecting pipe 20 and the accuracy of the filling volume.

[0032] Working principle: Start motor 5, which drives rotating shaft 6 to rotate, causing stirring plate 7 to stir and mix the aqueous solvent in stirring tank 3. As rotating shaft 6 rotates, the meshing of first bevel gear 9 and second bevel gear 10 drives rotating rod 11 and cam 12 to rotate. Cam 12 pushes filter screen 13, causing it to vibrate under the action of elastic component fixing rod 27, slide rod 15, and first spring 16, preventing filter screen 13 from clogging and ensuring effective filtration of impurities in the aqueous solvent. Open valve 26, and the stirred and filtered aqueous solvent in stirring tank 3 flows into metering tank through connecting pipe 25. 19. Based on the height of the tank to be filled, pull the moving plate 23 to compress the second spring 24, causing the insertion rod 22 to exit from the through hole of the connecting pipe 20. After adjusting the connecting pipe 20 to a suitable height, release the moving plate 23. The elastic force of the second spring 24 pushes the insertion rod 22 into the corresponding through hole, fixing the position of the connecting pipe 20 to adapt to tanks of different heights. Start the electric push rod 17, which pushes the push plate 18 down, squeezing the water-based solvent in the metering tank 19 through the connecting pipe 20 to complete the filling operation. After filling is completed, the electric push rod 17 drives the push plate 18 to rise and reset, waiting for the next filling instruction.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
