Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of chemical reagent and auxiliary processing equipment, and more specifically, to a chemical reagent and auxiliary filling device that prevents leakage. Background Technology
[0002] Currently, chemical reagent filling is usually carried out using a filling production line, which mainly includes a frame equipped with several peristaltic pumps. The peristaltic pumps draw chemical reagents from the reagent barrels and transport them through pipelines to the filling tube. The filling tube is lowered by a lifting plate and extends into the auxiliary agent bottle for filling. The auxiliary agent bottles are then neatly arranged by a conveyor belt and transported sequentially to the labeling and packaging process.
[0003] The above filling process is applicable to common chemical reagents. However, for some toxic chemical reagent additives, such as alkylphenol polyoxyethylene ether (APEO), when APEO comes into contact with water, the EO chain of APEO is opened during the biodegradation process, and it is metabolized into short ethylene oxide chains, carboxylic acids and alkylphenols. As these accumulate in organisms, they are amplified in higher levels of the biological chain due to bioaccumulation, thus becoming toxic to humans.
[0004] In existing filling equipment, the opening area between the filling tube and the bottle mouth of the auxiliary agent is relatively large. When the filling tube is pulled out of the auxiliary agent bottle after filling, the filling tube vibrates during the upward movement of the lifting plate. In addition, there is residual auxiliary agent liquid on the filling tube body. Therefore, during the upward pulling process, chemical reagents and auxiliary agents are easy to overflow outside the auxiliary agent bottle and enter the surrounding environment of the equipment, causing toxic pollution to the factory area and affecting the health of the factory workers. This does not conform to the concept of green and environmentally friendly processing. Utility Model Content
[0005] The purpose of this invention is to provide a chemical reagent and auxiliary agent filling device that prevents leakage. This device uses an openable and closable sealing component at the contact point between the filling tube and the bottle opening to block and isolate any overflowing toxic auxiliary agents after filling, thereby preventing leakage and ensuring a safe environment for auxiliary agent production in the factory.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A leakage-preventing chemical reagent auxiliaries filling device includes a frame. Several peristaltic pumps are mounted on the front side of the frame. The inlets of these pumps are connected to the interior of an auxiliaries container via pipes, and the outlets are connected to different filling tubes via pipes. Each filling tube is connected to a rear lifting plate via a support plate. The lifting plate is mounted on columns on both sides. A top plate and a bottom plate are installed between the columns. A lifting drive cylinder connects the upper surface of the bottom plate and the lower surface of the lifting plate. A transport trough is located below each filling tube. The transport trough is used to achieve horizontal linear transport of several auxiliaries bottles after being limited and blocked by external limiting strips. L-shaped supports with inwardly oriented sections are located at the front and rear of the transport trough. Guide rods connect the two sides of the L-shaped supports, and leak-proof components are slidably mounted on the guide rods.
[0008] As a further optimization of this solution, the leak-proof component includes two parallel concave frames. The inner surface of the outer concave frame is provided with a number of outer seals at equal intervals, and the inner surface of the inner concave frame is provided with a number of inner seals at equal intervals. The lower outer ends of both sides of the two parallel concave frames are connected to the L-shaped bracket with a push cylinder. The telescopic piston rod of the push cylinder is connected and fixed to the outer surface of the two parallel concave frames.
[0009] As a further optimization of this solution, both the outer and inner sealing elements are composed of two semicircular rings, with the radius of the upper semicircular ring being smaller than that of the lower semicircular ring. The upper semicircular ring is attached to the outer side of the filling tube, and the lower semicircular ring is attached to the outer side of the mouth of the auxiliary agent bottle. After the outer and inner sealing elements are aligned and spliced, they seal the area between the filling tube and the auxiliary agent bottle. A semi-circular sealing ring is embedded in the middle of the inner side of both the upper and lower semicircular rings of the outer and inner sealing elements.
[0010] As a further optimization of this solution, a strip-shaped groove is machined at the inner edge of the inner side of the outer seal, and a strip-shaped sealing strip is bonded at the inner edge of the inner side of the inner side of the inner seal, with the strip-shaped sealing strip being aligned and embedded inside the strip-shaped groove.
[0011] As a further optimization of this solution, the filling tube is aligned downwards and inserted into the auxiliary agent bottle directly below by the lifting plate.
[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows:
[0013] This invention utilizes an L-shaped bracket and two parallel concave frame structures to equidistantly space several outer and inner sealing elements on the front and rear sides of the auxiliary agent bottle opening. By pushing the telescopic piston rod of a cylinder, the concave frame is moved inwards, causing the outer and inner sealing elements to fit together. The outer and inner sealing elements, after alignment and splicing, seal the area between the filling tube and the auxiliary agent bottle. The designed sealing ring and sealing strip structure further seals this area, preventing leakage of the auxiliary agent when the filling tube is pulled up after filling, thus ensuring a safe environment for auxiliary agent production in the factory.

Detailed Implementation
[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0021] In order to address the problem that the existing filling tubes and auxiliary bottle openings have large perforations, and that the filling tubes vibrate as they move up and down with the lifting plate, causing chemical reagents and auxiliary agents to easily spill out of the auxiliary bottle during the filling process, resulting in toxic pollution to the factory area and affecting the health of the factory workers;
[0022] like Figure 1As shown, this application includes a frame 1. Several peristaltic pumps 2 are installed on the front side of the frame 1. The inlets of the peristaltic pumps 2 are all connected to the inside of the auxiliary agent tank 3 through pipes 4, and the outlets of the peristaltic pumps 2 are all connected to different filling pipes 5 through pipes 4. The filling pipes 5 are all connected to the lifting plate 6 at the rear through a support plate. The lifting plate 6 is fitted on both sides of the column 7. A top plate and a bottom plate are installed between the columns 7. A lifting drive cylinder 13 is connected between the upper surface of the bottom plate and the lower surface of the lifting plate 6. A transport trough 8 is provided below the different filling pipes 5. The inside of the transport trough 8 is limited and blocked by the outer limit bar 9 to achieve horizontal straight transport of several auxiliary agent bottles 10. There are horizontally inward L-shaped brackets 11 at the front and rear of the transport trough 8. The two sides of the L-shaped brackets 11 are connected by guide rods 12. The guide rods 12 are slidably fitted with anti-leakage components.
[0023] like Figure 2 As shown, the leak-proof assembly includes two parallel concave frames 14, wherein the inner side of the outer concave frame 14 is provided with a number of outer seals 15 at equal intervals, and the inner side of the inner concave frame 14 is provided with a number of inner seals 16 at equal intervals.
[0024] like Figure 3 As shown, a push cylinder 17 is connected between the lower outer ends of the two parallel concave frames 14 and the L-shaped bracket 11. The telescopic piston rod of the push cylinder 17 is connected and fixed to the outer side of the two parallel concave frames 14.
[0025] like Figure 4 and Figure 5 As shown, both the outer seal 15 and the inner seal 16 are composed of two semicircular rings, with the radius of the upper semicircular ring being smaller than that of the lower semicircular ring. The upper semicircular ring is attached to the outer side of the filling tube 5, and the lower semicircular ring is attached to the outer side of the mouth of the auxiliary agent bottle 10. After the outer seal 15 and the inner seal 16 are aligned and spliced, they seal the area between the filling tube 5 and the auxiliary agent bottle 10. A semicircular sealing ring 18 is embedded in the middle of the inner side of the upper and lower semicircular rings of the outer seal 15 and the inner seal 16. A strip-shaped groove 20 is machined at the inner edge of the inner side of the outer seal 15, and a strip-shaped sealing strip 19 is bonded at the inner edge of the inner side of the inner side of the inner seal 16. The strip-shaped sealing strip 19 is aligned and embedded inside the strip-shaped groove 20.
[0026] Specifically, in the initial position, the filling tube 5 is positioned directly above the mouths of all the auxiliary agent bottles 10. The lifting drive cylinder 13 is activated via the control panel, pulling down the lifting plate 7. Driven by the lifting plate 7, the filling tube 5 extends downwards into the mouths of the auxiliary agent bottles 10 directly below. Then, the peristaltic pump 2 is activated, drawing auxiliary agents from the auxiliary agent container 3 and filling them into the corresponding auxiliary agent bottles 10 through the filling tube 5. After the peristaltic pump has filled the set amount of auxiliary agent, and the filling is complete, the push cylinder 17 is activated, pushing the concave frame 14 inwards from the front and rear sides of the auxiliary agent bottle 10. This causes the outer seal 15 and the inner seal 16 to fit inwards, thus... After the outer seal 15 and the inner seal 16 are aligned and spliced, the area between the filling tube 5 and the auxiliary agent bottle 10 is sealed. The sealing ring 18 and the sealing strip 19 are used to seal the area between the filling tube 5 and the auxiliary agent bottle 10. The peristaltic pump 2 is stopped. The lifting drive cylinder 13 is used to pull up the lifting plate 7 and pull the filling tube 5 out from between the outer seal 15 and the inner seal 16. The residual auxiliary agent will be blocked and isolated by the outer seal 15 and the inner seal 16 to prevent the residual auxiliary agent in the filling tube 5 from leaking. At the same time, the outer seal 15 and the inner seal 16 play a guiding role in the bottle mouth area, reducing the vibration and leakage during the up and down movement of the filling tube 5.
