Abstract
Description
Technical Field
[0001] This utility model relates to the field of online detection and analysis technology, specifically to an automatic solid drug dosing reaction device. Background Technology
[0002] Online detection and analysis technology serves as a core support for industrial process control, environmental monitoring, and water quality treatment, providing data for production regulation, quality control, and environmental compliance. Currently, online analyzers are often limited to performing analyses after reagents have been prepared into liquids. Therefore, many analytical methods involving solid reagents are discarded. For example, in the titration analysis of metal ions such as calcium, copper, nickel, and zinc, ammonium purpurate indicators are used. The preparation method for ammonium purpurate indicators involves grinding ammonium purpurate and sodium chloride into powder in a specific ratio. Similarly, online monitoring of COD in water requires the addition of potassium dichromate oxidant, and the detection of heavy metals in soil requires the addition of chelating agents to enrich target ions. Therefore, achieving real-time, accurate, and continuous solid reagent dosing in online analyzers is crucial for expanding the development potential of online detection and analysis technology. Utility Model Content
[0003] The purpose of this invention is to provide an automatic solid drug dosing reaction device to achieve real-time, accurate, and continuous solid drug dosing in an online analyzer.

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] like Figure 1 and Figure 2 As shown, this utility model discloses an automatic solid drug dosing reaction device, including: an axial motion mechanism 1, a solid drug tube 2, and a reaction vessel 3. The solid drug tube 2 is installed on the axial motion mechanism 1, and the reaction vessel 3 is placed below the solid drug tube 2. The solid drug tube 2 moves towards the reaction vessel 3 under the control of the axial motion mechanism 1.
[0025] The solid medicine tube 2 has a dosing port 21 at its top and a dispensing port 22 at its bottom. A switch valve 23 is installed above the dispensing port 22. A medicine chamber 24 is located between the dosing port 21 and the switch valve 23. A miniature pressure sensor (not shown in the figure) is installed in the switch valve 23 to control the dosage. In this embodiment, the miniature pressure sensor has a range of 0-500 g and an accuracy of ±0.01 g, and is used in conjunction with a transmitter.
[0026] The top of the reactor 3 is provided with a solid dosing port 311, and several baffles 312 are movably installed on the solid dosing port 311. The solid drug tube 2 is fitted with a pull rope fixing seat 25 on the outer wall of the dosing port 22. Several pull ropes 251 are installed on the pull rope fixing seat 25. The pull ropes 251 are connected to the baffles 312 respectively. The opening and closing of the solid dosing port 311 is controlled by the change of tension between the pull ropes 251 and the baffles 312.
[0027] In this embodiment, to avoid redundant setting of the pull rope 251 and ensure the stability of the tension direction between the pull rope 251 and the baffle 312, the axial motion mechanism 1 is a single axial motion mechanism and a Z-axis motion mechanism. The reaction vessel 3 is placed below the solid drug tube 2, so that the solid drug addition port 311 is located directly below the drug inlet 22.
[0028] Secondly, combining Figure 3 and Figure 4 As shown, a groove 313 is provided around the solid dosing port 311. Baffles 312 are arranged in a circle around the solid dosing port 311. One end of the baffles 312 is connected to the groove 313 through a rotating shaft 314, and the other end is connected to the pull rope 251. A retaining spring (not shown in the figure) is installed on the rotating shaft 314 so that the baffles 312 are placed in the groove 313. When the pull rope 251 is tightened, the baffles 312 converge and close towards the solid dosing port 311.
[0029] In this embodiment, when the solid medicine tube 2 is in standby mode, the pull rope 251 between the pull rope fixing seat 25 and the baffle 312 is taut. At this time, the baffle 312 converges towards the solid medicine dispensing port 311 under the action of the pulling force, so that all the baffles 312 are assembled at the solid medicine dispensing port 311, and the solid medicine dispensing port 311 is in a closed state. When the solid medicine tube 2 is in operation mode, the distance between the pull rope fixing seat 25 and the baffle 312 decreases, and the pull rope 251 is in a relaxed state. At this time, the retaining spring on the rotating shaft 314 resets all the baffles 312, and the solid medicine dispensing port 311 opens. The shape and number of the baffles 312 are not limited here, as long as they can close the solid medicine dispensing port 311 when they converge.
[0030] In this embodiment, the reaction vessel 3 includes a shell 31 and a vessel body 32. A solid dosing port 311 is disposed on the shell 31, and the top of the vessel body 32 has an opening 321 corresponding to the solid dosing port 311. The solid dosing port 311 and the opening 321 are connected, and a valve 322 is installed on the opening 321. When a solid drug is added from the solid dosing port 311, the solid dosing port 311 closes, and at this time, the valve 322 at the opening 321 opens, allowing the solid drug stored between the solid dosing port 311 and the opening 321 to be added into the vessel body 32 for reaction.
[0031] Furthermore, the axial motion mechanism 1 includes: a motor mounting base 11, a motor 12, a lead screw 13, and a coupling 14. The motor 12 and the lead screw 13 are mounted on the motor mounting base 11 and connected to each other. The solid medicine tube 2 is mounted on one end of the coupling 14, and the other end of the coupling 14 is fitted onto the lead screw 13.
[0032] In this embodiment, the axial motion mechanism 1 further includes a flat plate fixing frame 15, which is fixed to one side of the motor mounting base 11. The flat plate fixing frame 15 is provided with a strip-shaped through slot 151, through which the coupling 14 passes. The coupling 151 is provided with limit switches at its upper and lower ends, with the upper end being a first limit switch 141 and the lower end being a second limit switch 142. Both the first limit switch 141 and the second limit switch 142 are located within the through slot 151 and are electrically connected to the motor 12.
[0033] When the solid medicine tube 2 descends to the preset position, the second limit switch 142 abuts against the inner wall at the lower end of the through-slot 151, thereby controlling the motor 12 to stop operating. After the solid medicine is added, the motor 12 reverses its direction, and the solid medicine tube 2 rises. When the solid medicine tube 2 rises to the highest position, the first limit switch 141 abuts against the inner wall at the upper end of the through-slot 151, thereby controlling the motor 12 to stop operating.
[0034] Typically, the motor 12 can be timed according to the time required for the drug addition process, and then reversed. By setting the reverse rotation time, the solid drug tube 2 is stopped at a set position without having to be reset to the highest position. At this time, the setting of the first limit switch 141 can also prevent the coupling 14 from continuing to repeatedly impact the flat plate fixing frame 15 upwards in the event of a motor 12 failure, thus preventing damage to the device.
[0035] Furthermore, the outer wall of the solid medicine tube 3 is provided with a positioning protrusion (not shown in the figure), and the coupling 14 is provided with a corresponding positioning groove (not shown in the figure). When the coupling 14 is fitted onto the solid medicine tube 2, the positioning protrusion is engaged in the positioning groove for limiting and fixing.
[0036] Furthermore, in this embodiment, to facilitate the addition and dispensing of solid medicines, the inner wall of the dosing port 22 is a funnel shape that converges inward and extends downward, while the dosing port 21 is a single-sided funnel shape that tilts inward on one side. Additionally, a micro-vibration device (not shown in the figure) is installed on the rope fixing seat 25, which can shake the solid medicines remaining on the inner wall of the dosing port 22 into the reaction vessel 3.
[0037] The above description is only a preferred embodiment of the present utility model. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
