Description

Technical Field

[0001] This utility model relates to the field of filling device technology, specifically a water treatment agent grading filling machine. Background Technology

[0002] Water treatment agents refer to chemical agents used for water treatment. They are widely used in industries such as chemical, petroleum, textile, printing and dyeing, construction, medicine and health, transportation, and urban and rural environmental protection to achieve the goals of water conservation and prevention of water pollution. Liquid water treatment agents require bottling during the production and processing process to facilitate subsequent transportation and sales; this bottling process is widely used.

[0003] Conventionally, filling volume control is achieved by detecting changes in the liquid level within the container. Once the set level is reached, the filling switch is activated in real-time. However, due to the large cross-sectional area of ​​the container, there is a significant error in the filling volume. Furthermore, because the liquid flow rate is not controlled to slow down as each bottle is nearing completion, excess liquid overflows, resulting in low filling accuracy.

[0004] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a water treatment agent grading and filling machine, which solves the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a water treatment agent grading and filling machine, including a filling station to be filled, with a filling equipment body and a raw material box directly above it. The upper side of the filling equipment body is connected to the raw material box through a feed pipe. A vertically arranged straight pipe is provided in the filling equipment body, and a grading pipe with an appropriate inner diameter is provided inside the straight pipe. The top and bottom of the grading pipe are sealed. The grading pipe is lifted and lowered by a lifting cylinder. Multiple independently used temporary storage chambers are movably inserted into the bottom of the straight pipe. The different temporary storage chambers have different volumes. A piston is formed in each of the temporary storage chambers. The piston is pulled and pushed by external force.

[0009] Preferably, the bottom of the straight tube slopes and tapers from the outside to the inside to form a spray head, and the bottom of the grading tube is adapted to the shape of the bottom of the straight tube.

[0010] Preferably, the lifting cylinder is supported on the upper end of the straight pipe, and the lower part of the output end is connected to the top of the classifier pipe.

[0011] Preferably, the grading tube has an opening at its upper end and multiple long grooves at its lower end that correspond one-to-one with the positions of the temporary storage chamber.

[0012] Preferably, the length of the long groove is designed to be larger than the diameter of the connecting opening of the temporary storage cavity.

[0013] Preferably, the assembled temporary storage chamber is supported on the straight pipe by a connecting rod, and the temporary storage chamber can be sealed with a sealing cover to seal the corresponding part of the straight pipe.

[0014] (III) Beneficial Effects

[0015] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] 1. This utility model discloses a water treatment agent grading and filling machine. The main body of the filling equipment is equipped with multiple temporary storage chambers that can be flexibly switched and used individually. The different temporary storage chambers have different volumes and can be replaced and assembled as needed. Each temporary storage chamber contains a piston. Because the volume of water treatment agent drawn and pushed by the piston is always the same each time, different temporary storage chambers can be directly adapted to packaging bottles of different sizes to achieve grading and filling.

[0017] 2. The present invention relates to a water treatment agent grading and filling machine. In the main body of the filling equipment, the grading tube is lifted and blocked by the lifting cylinder. At this time, the piston of the temporary storage chamber returns to its original position, and the water treatment agent is filled from the nozzle downwards for the first time. Finally, the grading tube descends to the initial position, and its bottom sinks to the nozzle position to discharge the remaining water treatment agent for the second time until the filling is complete. The filling process is more accurate.

[0018] 3. The water treatment agent grading and filling machine of this utility model uses a filling equipment body in which the size of the long groove is designed to be as large as possible than the connecting diameter of the temporary storage chamber. This allows the piston in the temporary storage chamber to be quickly extracted in advance when the grading tube is lowered to its original position. In the ideal state, the grading tube is completely extracted the moment it is lowered to its original position. At this time, the grading tube can be directly lifted, reducing the filling time.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 As shown: A water treatment agent grading and filling machine includes a turntable 2 driven to rotate at its bottom by a motor. Multiple placement tanks 3 are circumferentially and evenly spaced on the turntable 2. One placement tank 3 to be filled serves as the filling station, with a lifting cylinder 4 located directly below it. A filling equipment body 7 is located axially above the placement tank 3. A raw material tank 6 is mounted on one side of the filling equipment body 7 via a bracket 5. The raw material tank 6 delivers the water treatment agent into the filling equipment body 7 through a feed pipe 9.

[0026] The turntable 2 has a through groove for placing the placement part of the trough cylinder 3. When the trough cylinder 3 is rotated to the filling station, it is pushed upward by the lifting cylinder 4 to the output position close to the main body 7 of the filling equipment, so as to achieve fast and accurate filling.

[0027] In this embodiment, the water treatment agent is filled in a liquid state.

[0028] like Figure 2 As shown, the main body 7 of the filling equipment has a vertically arranged straight pipe 71, which is supported by a support rod 1 connected to the bracket 5. The bottom of the straight pipe 71 slopes and narrows from the outside to the inside to form a spray head. A classifying pipe 73 with an inner diameter adapted to the straight pipe 71 is provided inside the straight pipe 71. The top and bottom of the classifying pipe 73 are sealed, and the bottom is adapted to the bottom shape of the straight pipe 71. A lifting cylinder 8 is provided above it. The lifting cylinder 8 is supported at the upper end of the straight pipe 71, and its output end is connected downward to the upper end of the classifying pipe 73.

[0029] Multiple temporary storage chambers 72 are circumferentially inserted into the bottom of the straight tube 71. These chambers have different volumes and can be interchanged as needed, and can be used independently. Each chamber 72 contains a piston, which is pulled or pushed by external force (not shown in the illustration, but a conventional cylinder can be used). Because the volume of water treatment agent pulled or pushed by the piston remains the same each time, different temporary storage chambers 72 can be directly adapted to different sizes of packaging bottles, achieving precise grading and filling.

[0030] As attached Figure 2As shown, when the temporary storage chamber 72 is not assembled, the corresponding part of the straight pipe 71 can be sealed with a sealing cover 10. Simultaneously, the assembled temporary storage chamber 72 can be supported on the straight pipe 71 via a connecting rod 74. Only five assembly positions are shown in the illustration; more or fewer can be added as needed.

[0031] The grading tube 73 has an opening 75 on the upper side and multiple long grooves 76 on the lower side that correspond one-to-one with the positions of the temporary storage chamber 72. The opening 75 is used to receive the water treatment agent output from the raw material box 6, and the long grooves 76 are adapted to the temporary storage chamber 72.

[0032] For usage instructions, please refer to the appendix. Figure 3-4 As shown, one of the suitable temporary storage chambers 72 is selected for use. The water treatment agent in the raw material tank 6 is first drawn into it by the piston. This state is as shown in the attached figure. Figure 3 As shown, it forms a passage with the feed pipe 9 through the classifier tube 73. Then, the classifier tube 73 is lifted and blocked by the lifting cylinder 8. At this time, the piston of the temporary storage chamber 72 returns to its original position, and the water treatment agent is filled from the nozzle downwards. Finally, the classifier tube 73 descends to the initial position, and its bottom sinks to the nozzle position to discharge the remaining water treatment agent for the second time until it is completely filled. The water treatment agent is then pre-stored for the next filling (pre-stored in the temporary storage chamber 72).

[0033] Since the amount of water treatment agent drawn by the piston is the same each time, the residual amount of water treatment agent in the grading tube 73 has little impact on the continuous filling process and can be disregarded.

[0034] To ensure extraction time, the size of the long groove 76 can be designed to be as large as possible than the diameter of the connecting port 75 of the temporary storage chamber 72. This allows the piston in the temporary storage chamber 72 to quickly extract the grading tube 73 before it is lowered to its original position. Ideally, the grading tube 73 should be completely extracted the moment it is lowered to its original position, allowing the grading tube 73 to be lifted directly, thus reducing filling time.

[0035] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
