Description

Technical Field

[0001] This utility model relates to the field of atomic fluorescence spectrophotometer technology, and in particular to an atomic fluorescence spectrophotometer draining device. Background Technology

[0002] An existing automatic draining device for an atomic fluorescence spectrometer (publication number CN221846429U) describes a process where waste liquid generated by the spectrometer is discharged into a collection tank via a drain pipe and then into a sedimentation tank. As the waste liquid increases, it compresses a first spring, causing the sedimentation tank to descend until a drain hole is moved into the inner cavity of the sedimentation tank. The waste liquid then drains through the drain hole and is discharged through a drain pipe. During the descent, a first gear is driven by a first toothed plate, which in turn drives a lead screw. The lead screw drives a threaded block, which in turn moves a brush roller. A second gear, driven by a second toothed plate, then rotates the brush roller to clean the bottom of the sedimentation tank, preventing impurities from adhering to the bottom and becoming difficult to clean. However, in this device, the brush rollers are located on both sides of the drain pipe. This limits the cleaning area at the bottom of the sedimentation tank, and the area parallel to the drain pipe cannot be cleaned, potentially leading to excessive sediment buildup and affecting the device's effectiveness. Utility Model Content

[0003] The purpose of this invention is to provide a liquid discharge device for an atomic fluorescence spectrophotometer in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] An atomic fluorescence spectrophotometer draining device includes a spectrophotometer body, a drain pipe connected to one side of the spectrophotometer body, and a draining mechanism disposed at the end of the drain pipe for collecting and storing the drained liquid. The draining mechanism includes a support assembly disposed on one side of the spectrophotometer body, and a cleaning assembly for processing the drained liquid is disposed within the support assembly. The support assembly includes a support base fixed to the side wall of the spectrophotometer body, a mounting base fixed on the support base, a support cylinder connected to the lower end of the mounting base, and an open upper end of the support cylinder communicating with the drain pipe. The support cylinder has a step at one end, and a filter screen is installed on the step. A liquid outlet pipe is installed at the center of the lower end of the support cylinder. The cleaning component includes a guide pipe fixed inside the liquid outlet pipe. The upper end of the guide pipe is shaped like a truncated cone. A guide hole is opened on the outer wall of the lower side of the guide pipe. A rotating cylinder is fitted on the outer diameter of the guide pipe. A spring is fitted on the lower side of the rotating cylinder on the outer diameter of the guide pipe and the liquid outlet pipe. A liquid storage cylinder is installed inside the support cylinder on the rotating cylinder. A cleaning scraper is installed at the upper end of the rotating cylinder through the liquid storage cylinder. A power component that makes the rotating cylinder rotate is installed at the lower end of the rotating cylinder.

[0006] Further configuration: The power assembly includes a worm gear mounted on the rotating cylinder, the worm gear being located on the lower side of the liquid storage cylinder, a worm being rotatably mounted on the lower side of the liquid storage cylinder, a gear being fixed at one end of the worm, and a vertical notch groove being provided on the inner wall of the support cylinder at a position corresponding to the gear, and a rack being vertically arranged in the notch groove to mesh with the gear.

[0007] Further configuration: The rotating cylinder is rotatably connected to the liquid storage cylinder and the guide pipe, and the worm gear meshes with the worm wheel for rotation.

[0008] Further configuration: The support cylinder and the mounting base are connected by threads, and the upper end of the liquid storage cylinder contacts the lower end of the filter screen after installation.

[0009] Further setting: The lower end face of the cleaning scraper is tangent to the inner bottom of the liquid storage tank.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] By incorporating the support and cleaning components of the drainage mechanism, the filtered liquid enters the storage tank. As the overall weight of the storage tank increases, it overcomes the spring support force and moves downwards. Alternatively, when the storage tank moves upwards after drainage, the power component converts the vertical movement into the rotation of the rotating drum and cleaning scraper. The cleaning scraper agitates the sediment at the bottom of the storage tank, facilitating the separation of the guide hole on the upper side of the guide pipe from the rotating drum. This allows the stored liquid in the storage tank to enter the guide pipe and flow out from the outlet pipe, improving the comprehensiveness of cleaning the bottom of the storage tank.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-5 As shown, an atomic fluorescence spectrophotometer draining device includes a spectrophotometer body 1, a draining pipe 2 connected to one side of the spectrophotometer body 1, and a draining mechanism disposed at the end of the draining pipe 2 for collecting and storing the drained liquid.

[0024] In this embodiment: the drainage mechanism includes a support component disposed on one side of the photometer body 1, and a cleaning component for processing the drainage is disposed inside the support component;

[0025] The support assembly includes a support base 3 fixed to the side wall of the photometer body 1, a mounting base 41 fixed on the support base 3, a support cylinder 42 connected to the lower end of the mounting base 41, the upper end of the support cylinder 42 being open and communicating with the drain pipe 2, a step provided at the upper end of the support cylinder 42, and a filter screen 44 provided on the step, and a drain pipe 43 provided at the center of the lower end of the support cylinder 42, the support cylinder 42 and the mounting base 41 being connected by threads, which facilitates the disassembly and installation of the support cylinder 42 and the mounting base 41, and the processing of the filter screen 44;

[0026] The cleaning assembly includes a guide tube 45 fixed inside the outlet pipe 43. The upper end of the guide tube 45 is shaped like a truncated cone. A guide hole is formed on the lower outer wall of the guide tube 45. A rotating cylinder 47 is fitted onto the outer diameter of the guide tube 45. A spring 46 is fitted onto the lower side of the rotating cylinder 47 on the outer diameter of both the guide tube 45 and the outlet pipe 43. A storage cylinder 48 is installed inside the support cylinder 42 on the rotating cylinder 47. A cleaning scraper 49 is installed at the upper end of the rotating cylinder 47 through the storage cylinder 48. A power assembly for rotating the rotating cylinder 47 is provided at the lower end of the rotating cylinder 47. 47 is rotatably connected to the liquid storage cylinder 48 and the guide pipe 45. After the upper end of the liquid storage cylinder 48 is installed, it contacts the lower end of the filter screen 44. The lower end face of the cleaning scraper 49 is tangent to the inner bottom of the liquid storage cylinder 48. During the up and down movement of the liquid storage cylinder 48, the up and down movement is converted into the rotation of the rotating cylinder 47 and the cleaning scraper 49 by the power component. The cleaning scraper 49 stirs the sediment at the bottom of the liquid storage cylinder 48. After the guide hole on the upper side of the guide pipe 45 is misaligned and separated from the rotating cylinder 47, the stored liquid in the liquid storage cylinder 48 enters the guide pipe 45 and flows out from the outlet pipe 43.

[0027] The power assembly includes a worm gear 410 mounted on the rotating cylinder 47. The worm gear 410 is located below the liquid storage cylinder 48. A worm 411 is rotatably mounted on the lower side of the liquid storage cylinder 48. A gear 412 is fixed to one end of the worm 411. A vertical notch is provided on the inner wall of the support cylinder 42 at a position corresponding to the gear 412. A rack 413 that meshes with the gear 412 is vertically arranged in the notch. The worm 411 meshes with the worm gear 410 and rotates. As the amount of liquid in the liquid storage cylinder 48 increases, the overall weight of the liquid storage cylinder 48 overcomes the supporting force of the spring 46 and moves downward. When the gear 412 at the end of the worm 411 on the lower side of the liquid storage cylinder 48 moves downward, it meshes with the rack 413, driving the gear 412 and the worm 411 to rotate. The meshing of the worm 411 and the worm gear 410 provides power for the rotation of the rotating cylinder 47.

[0028] The working principle and usage process of this utility model are as follows: The liquid generated during the use of the photometer body 1 is discharged into the cavity formed by the mounting base 41 and the support cylinder 42 through the drain pipe 2. It first passes through the filter screen 44 and enters the storage cylinder 48. As the amount of liquid in the storage cylinder 48 increases, the overall weight of the storage cylinder 48 overcomes the supporting force of the spring 46 and moves downward. When the gear 412 at the end of the worm 411 on the lower side of the storage cylinder 48 moves downward, it meshes with the rack 413, driving the gear 412 and the worm 411 to rotate. The worm 411 meshes with the worm wheel 410, driving the rotating cylinder 47 and the cleaning scraper 49 to rotate. The cleaning scraper 49 stirs the bottom of the storage cylinder 48 until the guide hole on the upper side of the guide pipe 45 is misaligned and separated from the rotating cylinder 47. The stored liquid in the storage cylinder 48 enters the guide pipe 45 and flows out from the outlet pipe 43.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
