Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical dilution technology, and in particular to a pharmaceutical dilution device for preventing scaling in anaerobic systems. Background Technology

[0002] Anaerobic systems can remove COD from leachate (leachate produced by waste incineration plants), reducing the load on subsequent leachate treatment processes. Because leachate contains a complex variety of substances and has a high salt content, it is highly prone to scaling. During long-term operation, the anaerobic tank and its auxiliary pipelines are susceptible to scaling, which reduces the overall circulation flow of the anaerobic system and affects its normal operation. Therefore, pretreatment of the leachate is necessary to reduce the risk of scaling in the anaerobic tank and auxiliary pipelines before the COD in the pretreated leachate is removed by the anaerobic system. Currently, a common leachate pretreatment method involves adding agents (scale inhibitors) to the leachate. These scale inhibitors disperse the sparingly soluble inorganic salts in the leachate, preventing or interfering with their precipitation and scaling. Scale inhibitors typically require specific formulation adjustments based on the application scenario before use.

[0003] In the process of preparing scale inhibitors, it is usually necessary to dilute the scale inhibitors according to a certain ratio. The existing operation method is to pour the scale inhibitor concentrate into the dissolving tank and open the dilution water valve at the same time to mix it according to a certain ratio. Although this preparation method is simple to operate, it has the problem that the control ratio of the added water to the scale inhibitor concentrate is not precise enough, which can easily lead to insufficient dilution or over-dilution, resulting in some unnecessary waste.

[0041] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0042] In this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0043] Given that the current technology has problems with the ratio of water to scale inhibitor stock solution not being precise enough, it is easy to cause insufficient or excessive dilution, resulting in some unnecessary waste.

[0044] like Figure 1-3 As shown in the figure, this utility model embodiment provides a dilution device for preventing scaling in anaerobic systems, including: a dilution tank 1 and a scale inhibitor stock solution tank 2 disposed on the dilution tank 1.

[0045] The dilution tank 1 has a cavity, referred to as the dilution chamber 11, within which a mixing component 3 is installed. The mixing component 3 is configured to thoroughly mix the different liquids within the dilution chamber 11. A first observation window 12 is located on the front of the dilution tank 1, and a first liquid level gauge 13 is marked on the outer wall of the first observation window 12. The liquid level within the dilution chamber 11 can be clearly and directly observed through the first observation window 12 and the first liquid level gauge 13. An inlet pipe 7 is located at the upper end of the dilution tank 1, configured to deliver the diluent, and an outlet pipe 8 is located at the lower end, configured to deliver the diluted scale inhibitor concentrate.

[0046] The scale inhibitor stock solution tank 2 has a cavity, which is divided into a liquid dispensing chamber 21 and a liquid storage chamber 22 from left to right.

[0047] The liquid dispensing chamber 21 is configured for quantitative dispensing of the scale inhibitor stock solution, and the liquid storage chamber 22 is configured as the main place for storing the scale inhibitor stock solution.

[0048] A liquid-taking tube 6 is provided on one side of the liquid-taking chamber 21. One end of the liquid-taking tube 6 penetrates the wall of the liquid-taking chamber 21, and the other end extends into the dilution chamber 11. The liquid-taking chamber 21 is connected to the dilution chamber 11 through the liquid-taking tube 6. A second observation window 23 is provided on one side of the liquid-taking chamber 21, above the liquid-taking tube 6. A second liquid level gauge 24 is marked on the outer wall of the second observation window 23. By comparing the liquid level of the scale inhibitor stock solution in the liquid-taking chamber 21 with the second liquid level gauge 24 on the second observation window 23, quantitative liquid taking is achieved, which facilitates the acquisition of the corresponding amount of scale inhibitor stock solution from the storage chamber 22 according to the actual situation. A conveying assembly 4 is provided on the scale inhibitor stock solution tank 2. One end of the conveying assembly 4 is located in the liquid-taking chamber 21, and the other end is located in the storage chamber 22. The liquid-taking chamber 21 and the storage chamber 22 are connected by the conveying assembly 4. The conveying assembly 4 is configured to convey the scale inhibitor stock solution from the storage chamber 22 to the liquid-taking chamber 21.

[0049] Specifically, such as Figure 2 As shown, the mixing component 3 includes several parts such as a motor 31, a rotating shaft 32, and a stirring rod 33.

[0050] The rotating shaft 32 is rotatably disposed inside the dilution chamber 11, with one end located on one side of the inner wall of the dilution chamber 11 and the other end extending from one side of the inner wall of the dilution chamber 11 to the other side of the inner wall of the dilution chamber 11. The rotating shaft 32 is configured to carry other components.

[0051] The stirring rods 33 are fixedly arranged in the radial direction of the rotating shaft 32 and extend along the radial direction of the rotating shaft 32. There are multiple rods, which are arranged alternately and intermittently along the axial direction of the rotating shaft 32.

[0052] The motor 31 is mounted on the dilution tank 1, and its output end is connected to the rotating shaft 32.

[0053] Motor 31 drives shaft 32 to rotate, shaft 32 drives stirring rod 33 to rotate synchronously, stirring rod 33 to stir different liquids in dilution chamber 11 during rotation, so as to mix them thoroughly.

[0054] like Figure 3 As shown, the delivery assembly 4 includes: a U-shaped infusion hose 41 with its two ends connected to the storage chamber 22 and the dispensing chamber 21 respectively, and two sets of clamping plates 42 set at the lower end of the scale inhibitor stock solution tank 2 for clamping the infusion hose 41. When it is necessary to deliver the scale inhibitor stock solution in the storage chamber 22 to the dispensing chamber 21, the two sets of clamping plates 42 are opened, so that the channel inside the U-shaped infusion hose 41 is in a connected state, thereby allowing the scale inhibitor stock solution in the storage chamber 22 to be delivered to the dispensing chamber 21. After the delivery is completed, the infusion hose 41 is clamped by the clamping plates 42, so that the channel inside the infusion hose 41 is closed.

[0055] Furthermore, the two sets of buckle clamps 42 are hinged to each other. One set of buckle clamps 42 is provided with a protrusion 43, and the other set of buckle clamps 42 is provided with a buckle 44 that is matched and fastened to the protrusion 43. Through the cooperation of the protrusion 43 and the buckle 44, the opening and closing of the infusion tubing 41 channel can be controlled.

[0056] Furthermore, in order to more efficiently deliver the scale inhibitor stock solution in the storage chamber 22 to the liquid dispensing chamber 21, in this embodiment, a piston rod 5 is slidably disposed in the liquid dispensing chamber 21.

[0057] The piston rod 5 includes a piston plate 51 that slides against the inner wall of the liquid taking chamber 21 and a pull rod 52 that is disposed on the piston plate 51 and passes through the liquid taking chamber 21 to control the up and down movement of the piston plate 51. When the liquid taking chamber 21 takes a quantitative amount of liquid (scale inhibitor stock solution), it uses the piston rod 5 to extract the liquid, and then uses negative pressure to extract the scale inhibitor stock solution in the liquid storage chamber 22 into the liquid taking chamber 21.

[0058] Furthermore, to facilitate the control of opening and closing of the liquid collection tube 6 channels, in this embodiment, as follows... Figure 2 As shown, a first control valve 61 adapted to the liquid collection tube 6 is provided at one end of the liquid collection tube 6 near the liquid collection chamber 21. Similarly, a second control valve 71 is provided on the liquid inlet tube 7, and a third control valve 81 is provided on the liquid outlet tube 8.

[0059] Furthermore, to facilitate the extraction of the scale inhibitor stock solution from the storage chamber 22, in this embodiment, a vent cap 9 is provided on the wall of the storage chamber 22. During the extraction of the scale inhibitor stock solution from the storage chamber 22, the vent cap 9 is opened to allow external gas to fill the interior of the storage chamber 22, thereby balancing the pressure between the storage chamber 22 and the extraction chamber 21, thus achieving the purpose of facilitating the extraction of the scale inhibitor stock solution from the storage chamber 22.

[0060] In use, the external diluent is first delivered to the dilution chamber 11 through the inlet pipe 7. The level of the diluent is observed through the first level gauge 13 on the first observation window 12. When the required amount of diluent is reached, the inlet pipe 7 is closed, and then the vent cap 9 is opened. The U-shaped infusion hose 41 is connected through the two sets of clamps 42. Then, the access pipe 6 is closed through the first control valve 61. The piston rod 5 is used for extraction, and the scale inhibitor stock solution in the storage chamber 22 is extracted into the access chamber 21 through negative pressure. The amount of scale inhibitor stock solution in the access chamber 21 is obtained through the second level gauge 24 until the scale inhibitor in the access chamber 21 is reached. Once the required volume of the original solution is reached, extraction is stopped. Then, the U-shaped infusion hose 41 is closed using two sets of clamps 42, and the infusion pipe 6 is opened using the first control valve 61. The scale inhibitor original solution in the infusion chamber 21 is transported to the dilution chamber 11 through the infusion pipe 6 using the piston rod 5. The motor 31 is started, and the stirring rod 33 rotates under the drive of the motor 31. During the rotation, the stirring rod 33 stirs the diluent and scale inhibitor original solution in the dilution chamber 11 to ensure thorough mixing and dilution of the scale inhibitor original solution. Finally, the diluted scale inhibitor original solution is discharged through the outlet pipe 8 for further application.

[0061] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
