Description

Technical Field

[0001] This utility model relates to the field of injection device technology, and in particular to an injection device for preparing defoamer. Background Technology

[0002] Defoamers are additives used to eliminate foam. In the production and application processes of coatings, textiles, medicine, fermentation, papermaking, water treatment, and petrochemicals, a large amount of foam is generated, which in turn affects product quality and the production process. To inhibit and eliminate foam, a specific amount of defoamer is usually added during production. Defoamers reduce the surface tension of water, solutions, suspensions, etc., preventing foam formation or reducing or eliminating existing foam. Defoamers have a wide range of applications, including in the food industry, papermaking industry, water treatment, oil extraction industry, printing and dyeing industry, coatings industry, detergent industry, rubber latex industry, aerosol industry, daily chemical industry, pharmaceutical industry, and dairy industry.

[0003] The existing injection device has only the middle part fixed to the fixed device, and its push rod and liquid outlet are not fixed. During the injection process, the push rod and liquid outlet may shake or shift, resulting in unstable extrusion of the spinning solution.

[0004] An existing patent (publication number: CN213009753U) discloses a stepping injection device for defoamer production. By setting a pushing structure, it is mainly used to push the auxiliary agent inside the injection cylinder. In use, by pressing the control switch, the piston head slowly pushes the auxiliary agent inside the injection cylinder, thereby realizing automatic ejection of the auxiliary agent. Compared with the traditional manual structure, it is more convenient and less labor-intensive to use. It only requires pressing the control switch. Even during long-term use, it will not cause wear and tear on the hands. Moreover, the ejection speed is faster, which further improves work efficiency and can well meet people's needs.

[0005] To address the aforementioned issues, existing patents offer solutions, but these solutions are inconvenient for adding raw materials. In practical use, due to the lack of a dispensing structure, it is impossible to filter and continuously add defoamer raw materials. Impurities in the raw materials can easily clog the pipes, leading to fluctuations in injection pressure and equipment shutdowns. At the same time, operators need to frequently stop the machine to manually add materials, which not only wastes a lot of time and energy but also allows contaminants to seep in, affecting the purity of the defoamer product and production efficiency, thus reducing the practicality of the device.

[0006] To address this, a dispensing device for preparing defoamers is proposed. Utility Model Content

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] An injection device for preparing defoamer includes an injection cylinder 1, a pushing component 2 fixedly connected to the right side inside the injection cylinder 1, and an adding component 3 fixedly connected to the right side of the top of the injection cylinder 1. The pushing component 2 includes a moving plate 201, a moving motor 202 fixedly connected to the right side of the moving plate 201, and slide rods 203 are provided on the front and rear sides inside the moving plate 201.

[0029] The addition component 3 includes an addition tank 301. A top cover 302 is movably connected to the top of the addition tank 301, and a drain plate 303 is fixedly connected to the bottom inside the addition tank 301. A rotating motor 304 is fixedly connected to the top of the top cover 302, and a rotating rod 305 is fixedly connected to the output end of the rotating motor 304. The other end of the rotating rod 305 extends into the interior of the addition tank 301 and is fixedly connected to a baffle plate 306, which contacts the drain plate 303. A spiral blade 307 is fixedly connected to the surface of the rotating rod 305, and the spiral blade 307 is located inside the addition tank 301.

[0030] In this embodiment: the rotating motor 304 drives the rotating rod 305 to rotate, which in turn drives the baffle plate 306 to rotate at the leakage plate 303, thus adjusting the discharge port. This controls the flow rate and start / stop of the raw material addition and also filters the raw material to prevent impurities from clogging the injection cylinder 1, ensuring the normal feeding of the raw material. At the same time, under the action of the spiral blade 307, the rotating rod 305 drives the spiral blade 307 to rotate in the addition tank 301, which pushes the raw material to flow along the spiral blade 307 and then into the injection cylinder 1 to complete the addition operation. This ensures the continuous and stable feeding operation and improves the ease of use of the addition component 3. Then, the moving motor 202 drives the threaded rod 204 to rotate. Under the action of the internal thread of the threaded sleeve 206, the moving plate 201 and the pushing block 205 move smoothly. At the same time, under the action of the sliding rod 203, a linear guiding system is formed, which converts the rotational motion of the threaded rod 204 into the linear motion of the moving plate 201, preventing shaking and deviation, ensuring the smooth feeding operation, and improving the ease of use of the pushing component 2.

[0031] Specifically, such as Figure 4 As shown, the output end of the mobile motor 202 is fixedly connected to a threaded rod 204, and the other end of the threaded rod 204 extends into the interior of the injection cylinder 1 and is rotatably connected to a push block 205. A threaded sleeve 206 is threadedly connected to the surface of the threaded rod 204, and the threaded sleeve 206 is fixedly connected to the right side of the inner wall of the injection cylinder 1. A rubber sealing ring 207 is fixedly connected to the surface of the push block 205, and the surface of the rubber sealing ring 207 is in contact with the inner wall of the injection cylinder 1.

[0032] Specifically, such as Figure 1 , Figure 4 As shown, the left sides of the two slide rods 203 are fixedly connected to the two sides of the injection cylinder 1, and the moving plate 201 is slidably connected to the surface of the slide rods 203.

[0033] Specifically, such as Figure 4 As shown, the front and rear sides of the movable plate 201 are provided with movable holes 4 for use with the slide rod 203, and the surface of the slide rod 203 is in contact with the inner wall of the movable hole 4.

[0034] In this embodiment, the linear guide system formed by the cooperation of the slide bar 203 and the moving hole 4 can convert the rotational motion of the threaded rod 204 into the linear motion of the moving plate 201. This can limit the movement trajectory of the push block 205, prevent shaking and deviation, and also disperse the lateral force on the moving plate 201 during the movement, reduce jamming, ensure the smooth operation of the pushing component 2, and improve the stability of the pushing component 2.

[0035] Specifically, such as Figure 5As shown, a rubber sealing gasket 5 is fixedly connected to the side of the top cover plate 302 near the addition tank 301, and the surface of the rubber sealing gasket 5 is in contact with the inner wall of the injection cylinder 1. A feed pipe 6 is fixedly connected to the right side of the top of the top cover plate 302, and a filter frame 7 is movably connected inside the feed pipe 6.

[0036] Specifically, such as Figure 5 As shown, positioning plates 8 are fixedly connected to both sides of the top of the addition tank 301, and snap-fit ​​blocks 9 are rotatably connected to the top of the two positioning plates 8, and the top cover plate 302 is slidably connected to the surface of the positioning plates 8.

[0037] In this embodiment: the positioning plate 8 provides a guiding structure to the top cover 302, allowing the top cover 302 to move smoothly under the constraint of the positioning plate 8. This ensures that the rubber sealing gasket 5 is accurately embedded in the addition tank 301. The rubber sealing gasket 5 fills the gap between the top cover 302 and the addition tank 301, forming a sealed environment to prevent leakage. At the same time, rotating the buckle block 9 locks the top cover 302 in place, enabling quick installation and removal of the top cover 302 for easy maintenance and cleaning, thus improving the ease of use of the addition component 3. Furthermore, the combined use of the feed pipe 6 and the filter frame 7 not only allows the raw materials to be added smoothly into the addition tank 301, but also prevents impurities from entering, ensuring the cleanliness of the raw materials in the addition tank 301 and ensuring smooth material transport, thereby improving the practicality of the device.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a handle 10 is fixedly connected to the right side of the bottom of the injection cylinder 1, and the surface of the handle 10 is provided with anti-slip texture. A control button 11 is fixedly connected to the top left side of the handle 10, and the control button 11 is electrically connected to the push component 2 and the add component 3.

[0039] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, observation glass 12 is embedded in the front and rear sides of the injection cylinder 1, and the surface of the observation glass 12 is provided with scale.

[0040] In this embodiment, the combination of handle 10 and control button 11 not only provides a support point for the operator, making it easy for the operator to move the device, but also allows the operator to press control button 11 to control the operation of push component 2 and add component 3, ensuring the addition and push of raw materials. Furthermore, under the action of observation glass 12, the condition of raw materials in injection cylinder 1 can be observed in real time, and the amount of raw materials pushed can be observed and recorded with the help of scale, which improves the ease of use of the device.

[0041] Working Principle: When injecting raw materials, the operator first moves the device smoothly using handle 10. Then, the raw material is added to the addition tank 301 via the feed pipe 6. The raw material passes through the filter frame 7, which blocks impurities, ensuring the cleanliness of the raw material in the addition tank 301. When adding raw materials, the operator controls the addition component 3 using control button 11. The rotating motor 304 drives the rotating rod 305 to rotate, simultaneously rotating the baffle plate 306 at the leakage plate 303, thus adjusting the discharge port. This controls the flow rate and start / stop of the raw material addition and also performs secondary filtration. Simultaneously, the rotating rod 305 drives the spiral blades 307 to rotate, forming a spiral flow field that propels the raw material into the injection cylinder 1, completing the rapid addition of raw materials. After addition is complete, the rotating motor 304 is restarted to close the discharge port, and then the operation is controlled again via control button 11. The drive component 2 operates, starting the moving motor 202 to drive the threaded rod 204 to rotate. Under the action of the internal thread of the threaded sleeve 206, the moving plate 201, the pushing block 205, and the rubber sealing ring 207 move. At the same time, with the help of the linear guide system formed by the slide rod 203 and the moving hole 4, the rotational motion of the threaded rod 204 can be converted into the linear motion of the moving plate 201, preventing shaking and deviation, reducing jamming, and ensuring the smooth operation of the pushing operation. Meanwhile, with the help of the observation glass 12, the operator can observe the status of the raw material in the injection cylinder 1 in real time and record the data. After the pushing operation is completed, rotate the locking block 9 to release the lock on the top cover 302, remove it for cleaning and maintenance, reset it after maintenance, and rotate the locking block 9 to lock it, restoring the filtering and adding functions and ensuring the stable operation of the device.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
