Description

Technical Field

[0001] This utility model relates to the field of filling technology, and in particular to a filling device for acrylamide production with a metering mechanism. Background Technology

[0002] Acrylamide is a white crystalline chemical substance that is toxic and readily soluble in water. It is commonly used in the production of polymers such as polyacrylamide. Due to its properties, it requires explosion-proof equipment during bottling. Acrylamide is usually in a liquid state at this time and must be filled using specialized filling equipment.

[0003] Meanwhile, to ensure consistent filling volume each time, a metering mechanism is typically used to guarantee a fixed amount added each time, thus filling the container completely. However, in actual filling, because the volume of the metering mechanism is fixed, the amount of acrylamide that can be held in a single batch also remains constant. Since acrylamide containers come in various sizes, it becomes impossible to flexibly adjust the metering parameters when filling containers of different specifications. This affects the compatibility of filling with different containers and limits the versatility of the filling operation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that affect the adaptability of filling to different containers and limit the versatility of filling operations, and to propose a filling device for acrylamide production with a metering mechanism.

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

[0006] Design a filling device for acrylamide production with a metering mechanism, including a base, a storage tank fixedly connected to the base, a storage cylinder fixedly connected to the base, a piston abutting inside the storage cylinder, a threaded column fixedly connected to the lower end of the piston, a threaded cylinder threadedly connected to the lower end of the threaded column, the threaded cylinder being rotatably connected to the base via a bearing, multiple gears connected to the threaded cylinder via an adjusting mechanism, the number of teeth of the multiple gears decreasing sequentially from top to bottom, a rack meshing with the gears, the rack being moved by a moving mechanism, a connecting pipe connecting the lower end of the storage tank to the upper end of the storage cylinder, an injection pipe connecting the upper end of the storage cylinder, and a one-way valve provided on both the injection pipe and the connecting pipe.

[0007] Preferably, the storage cylinder is made of a transparent material.

[0008] Preferably, a positioning rod is fixedly connected to the lower end of the piston, and a positioning sleeve is fitted onto the lower end of the positioning rod, which is fixedly connected to the base.

[0009] Preferably, the moving mechanism includes a motor mounted on a base, a threaded rod fixedly connected to the output shaft of the motor, a moving block fixedly connected to the lower end of the rack, the threaded rod threaded through the moving block, and the moving block being limited by a limiting mechanism.

[0010] Preferably, the limiting mechanism includes a limiting rod, which is fixedly connected to the base and passes through the moving block.

[0011] Preferably, the adjusting mechanism includes a connecting sleeve, which is fixedly connected to multiple gears. The connecting sleeve is connected to the threaded cylinder via a coaxial rotation mechanism. A bolt is threaded through the connecting sleeve. Multiple threaded holes are equally spaced on the outer wall of the threaded cylinder. The bolt is threadedly connected to one of the threaded holes.

[0012] Preferably, the coaxial rotation mechanism includes a limiting strip, and a limiting groove is formed on the inner wall of the connecting sleeve, with the limiting strip slidably disposed in the limiting groove.

[0013] Preferably, a protective box is fixedly connected to the base, the protective box is rotatably connected to the threaded cylinder via a bearing, and a placement seat is provided on the protective box.

[0014] This invention discloses a filling device for acrylamide production with a metering mechanism. The advantages are as follows: by adjusting the position of the gears through the adjustment mechanism, the gear meshing with the rack can be switched. Due to different transmission ratios, the number of rotations of the threaded cylinder can be adjusted when driving the threaded cylinder to rotate, thereby adjusting the reciprocating displacement of the piston. This, in turn, adjusts the capacity of the storage cylinder when the piston is at its lowest point. Different gears correspond to different capacities to adapt to filling different containers, ensuring the versatility of the filling operation. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-5 A filling device for acrylamide production with a metering mechanism includes a base 1, a storage tank 2 fixedly connected to the base 1, a storage cylinder 3 fixedly connected to the base 1, a piston 18 abutting inside the storage cylinder 3, a threaded column 19 fixedly connected to the lower end of the piston 18, and a threaded cylinder 6 threadedly connected to the lower end of the threaded column 19. The piston 18 moves downward to draw acrylamide liquid from the storage tank 2 from the connecting pipe 4 into the storage cylinder 3.

[0023] The threaded cylinder 6 is rotatably connected to the base 1 via bearings. Multiple gears 14 are connected to the threaded cylinder 6 via an adjusting mechanism. The number of teeth on each gear 14 decreases sequentially from top to bottom. A rack 11 meshes with each gear 14, and the rack 11 moves via a moving mechanism. A connecting pipe 4 connects the lower end of the storage tank 2 to the upper end of the storage cylinder 3. An injection pipe 5 connects to the upper end of the storage cylinder 3. Both the injection pipe 5 and the connecting pipe 4 are equipped with one-way valves, which allow liquid to exit but not enter. The position of the gears 14 is adjusted via the adjusting mechanism, thereby switching the gear 14 meshing with the rack 11. Due to different transmission ratios, the number of rotations of the threaded cylinder 6 can be adjusted when driving it to rotate, thus adjusting the reciprocating displacement of the piston 18. This, in turn, adjusts the capacity of the storage cylinder 3 when the piston 18 is at its lowest position. Different gears 14 correspond to different capacities to accommodate different containers and ensure the versatility of the filling operation.

[0024] The storage cylinder 3 is made of transparent material and has scale lines on it to measure the amount of liquid inside.

[0025] A positioning rod 21 is fixedly connected to the lower end of the piston 18. A positioning sleeve 20 is sleeved on the lower end of the positioning rod 21. The positioning sleeve 20 is fixedly connected to the base 1. The positioning rod 21 and the positioning sleeve 20 limit the piston 18 and prevent the piston 18 from rotating.

[0026] Example 2: Refer to Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 1, the moving mechanism includes a motor 9, which is mounted on the base 1. A threaded rod 12 is fixedly connected to the output shaft of the motor 9, and a moving block 10 is fixedly connected to the lower end of the rack 11. The threaded rod 12 passes through the moving block 10, and the moving block 10 is limited by a limiting mechanism. When the threaded rod 12 rotates, it drives the moving block 10 to move back and forth, which in turn drives the rack 11 to move back and forth, causing the piston 18 to move back and forth, thereby drawing out or squeezing out the liquid in the storage cylinder 3.

[0027] The limiting mechanism includes a limiting rod 13, which is fixedly connected to the base 1. The limiting rod 13 passes through the moving block 10 and limits the moving block 10 to prevent the moving block 10 from rotating along with the threaded rod 12.

[0028] Example 3: Reference Figure 1-5 As another preferred embodiment of this utility model, based on embodiment 2, the adjustment mechanism includes a connecting sleeve 15, which is fixedly connected to multiple gears 14. The connecting sleeve 15 is sleeved on the threaded cylinder 6, and the connecting sleeve 15 and the threaded cylinder 6 are connected by a coaxial rotation mechanism. A bolt 16 is threaded through the connecting sleeve 15. Multiple threaded holes 17 are equally spaced on the outer wall of the threaded cylinder 6. The bolt 16 is threadedly connected to one of the threaded holes 17. By adjusting the position of the connecting sleeve 15 on the threaded cylinder 6, the bolt 16 is threadedly connected to the threaded hole 17, thereby realizing the switching of the gear 14 meshing with the rack 11, thus changing the transmission ratio between the gear and the rack.

[0029] When filling containers of different sizes, first switch the gear 14 that meshes with the rack 11, and then use bolts 16 to connect and fix it to the threaded hole 17. When the motor 9 rotates forward and backward, it drives the rack 11 to move back and forth, which in turn drives the gear 14 and the threaded cylinder 6 to rotate, thereby adjusting the position of the threaded column 19 in the threaded cylinder 6, and driving the piston 18 to move. When the piston 18 moves downward, it draws liquid from the storage tank 2 into the storage cylinder 3; when it moves upward, it discharges liquid from the injection tube 5 and injects it into the container to complete the filling.

[0030] Example 4: Reference Figure 5As another preferred embodiment of this utility model, based on embodiment 3, the coaxial rotation mechanism includes a limiting strip 22, which is fixedly connected to the outer wall of the threaded cylinder 6. A limiting groove is opened on the inner wall of the connecting sleeve 15, and the limiting strip 22 is slidably disposed in the limiting groove. When the threaded cylinder 6 rotates, it drives the limiting strip 22 to rotate, thereby causing the connecting sleeve 15 to rotate coaxially with the threaded cylinder 6. This can prevent the bolt 16 from rotating with the component in the fixed state and avoid damage to the bolt 16.

[0031] Example 5: Refer to Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 4, a protective box 8 is fixedly connected to the base 1. The protective box 8 is rotatably connected to the threaded cylinder 6 through a bearing. A placement seat 7 is provided on the protective box 8 for placing containers. The protective box 8 can prevent gears and other components from being exposed.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
