Description

Technical Field

[0001] This utility model relates to the field of instrument cleaning technology, and more specifically, to a cleaning device for chemical analysis instruments. Background Technology

[0002] In the field of chemical analysis, the cleanliness of chemical analysis instruments directly affects the accuracy of analytical results. However, existing cleaning devices for chemical analysis instruments have many problems. For example, the cleaning method is limited and cannot thoroughly clean all parts of the instrument; the way the instrument is fixed is not flexible enough to adapt to instruments of different shapes and sizes; and the recycling efficiency of the cleaning solution is low, resulting in resource waste.

[0003] For example, utility model patent CN219723901U discloses a cleaning device for chemical analysis instruments, including a housing, a cleaning tank inside the housing, a movable plate inside the cleaning tank, and a lifting structure connected to the movable plate. The upper surface of the movable plate is provided with a placement tray and a water spray assembly for rinsing. The placement tray has a slot for accommodating the chemical analysis instruments to be cleaned. This utility model's cleaning device can automatically clean multiple chemical analysis instruments at once, significantly improving cleaning efficiency compared to manual cleaning of only one instrument at a time. The utility model uses a lifting structure to move the movable plate and placement tray up and down within the cleaning tank. During actual cleaning, the chemical analysis instruments are simply placed in the placement slot, and the lifting structure lowers the movable plate and placement tray to the lowest position within the cleaning tank before cleaning. This avoids splashing of cleaning fluid and prevents environmental pollution.

[0004] While the aforementioned device can clean multiple instruments simultaneously and lowers them to the bottom for cleaning to prevent splashing and contamination, its open top means that some cleaning solution may still splash out when cleaning taller instruments. Furthermore, it cannot adapt to the size of the instruments, potentially causing wear and tear during cleaning. Additionally, the cleaning solution is for single use, which is not environmentally friendly and results in high operating costs. Therefore, designing an efficient, flexible, and environmentally friendly cleaning device for chemical analysis instruments is of significant practical importance. In light of this, we propose a cleaning device for chemical analysis instruments. Utility Model Content

Detailed Implementation

[0038] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] Please see Figures 1-6 A cleaning device for chemical analysis instruments includes a cleaning tank 1, a water tank 2 on one side of the cleaning tank 1 for storing cleaning solution, the water tank 2 being connected to the interior of the cleaning tank 1 via a connecting pipe 3, the inner end of the connecting pipe 3 being connected to a flow pipe 4, and several rotary spray heads 5 being installed on the flow pipe 4. The connecting pipe 3 connects the water tank 2 to the subsequent flow structure, and the rotary spray heads 5 achieve multi-angle, all-round spray cleaning to improve the cleaning effect. Inside the cleaning tank 1, four supports 7 are arranged in a matrix, and the four supports 7 are slidably connected to the same support plate 10, which is used to support the chemical analysis instrument. A fixing mechanism 11 is installed on the top surface of the support plate 10 via a turntable 12. A water circulation mechanism 13 is also provided between the cleaning tank 1 and the water tank 2.

[0041] In this embodiment, as Figure 2 As shown, a first liquid pump 6 is provided between the connecting pipe 3 and the water tank 2, and several rotary spray heads 5 are all facing the fixing mechanism 11; the first liquid pump 6 is used to pump the cleaning liquid in the water tank 2 into the flow pipe 4, and spray it out through the rotary spray heads 5.

[0042] Furthermore, such as Figure 2As shown, each of the four supports 7 has an electric slide rail 8 inside at the end away from the side wall of the cleaning tank 1. An electric slider 9 is slidably connected inside the electric slide rail 8. The four electric sliders 9 are fixedly connected to the four corners of the support plate 10. By controlling the electric slide rail 8, the electric sliders 9 can move inside the slide rail.

[0043] At the same time, such as Figure 3 As shown, a servo motor 16 is installed at the center of the bottom of the support plate 10. The output end of the servo motor 16 passes through the support plate 10 and is coaxially connected to the turntable 12. The servo motor 16 can drive the turntable 12 to rotate, thereby driving the instrument placed on the turntable 12 to rotate, which facilitates all-round cleaning.

[0044] like Figures 2-6 As shown, in this embodiment, the fixing mechanism 11 includes a ring-shaped fixing seat 1101. A ring rack 1102 is rotatably engaged with the inner side wall of the fixing seat 1101. A plurality of gears 1104 are meshed at equal intervals on the inner side of the ring rack 1102. The upper half of each gear 1104 is meshed with a rack 1108 that is slidably connected to the side wall of the fixing seat 1101. A movable plate 1109 is fixedly installed on the top end of the rack 1108.

[0045] Among them, the number of gears 1104, racks 1108 and moving plates 1109 are equal and their positions correspond one-to-one. The number of them is at least two, and in this embodiment, six are preferred.

[0046] Furthermore, such as Figures 5-6 As shown, the fixed base 1101 is fixed on the turntable 12 with the same center. Six limiting grooves 1106 are equally spaced on the top surface of the side wall of the fixed base 1101. The bottom end of the rack 1108 is integrally formed with a sliding column 1107 that slides and engages with the limiting grooves 1106.

[0047] like Figure 2 , Figure 4 As shown, six support plates 1103, equal in number and corresponding in position to gears 1104, are fixedly installed at equal intervals on the lower end of the inner side wall of the fixed base 1101. The central shaft of gear 1104 is rotatably inserted into the corresponding support plate 1103. A rotating motor 1105 is fixedly installed at the bottom of one of the support plates 1103. The output shaft of the rotating motor 1105 is coaxially fixedly connected to the gear 1104 at the corresponding position. The height of gear 1104 is greater than or equal to the sum of the heights of the ring rack 1102 and the rack 1108.

[0048] The rotating motor 1105 drives the gear 1104 to rotate, which in turn drives the ring rack 1102 to rotate through the meshing of the gear 1104 and the ring rack 1102; the rack 1108 meshes with the upper half of the gear 1104 at the corresponding position. When the ring rack 1102 rotates, the rack 1108 slides in the limiting groove 1106 through the gear 1104.

[0049] Specifically, the movable plate 1109 is fan-shaped, and several movable plates 1109 are distributed with the same center. An elastic rubber pad 1110 is fixedly connected to the top surface of the movable plate 1109. The elastic rubber pad 1110 can play a buffering and protective role when fixing the instrument. At the same time, by adjusting the position of the movable plate 1109, it can adapt to instruments of different sizes.

[0050] In this embodiment, as Figure 1 , Figure 3 As shown, the water circulation mechanism 13 includes a second liquid pump 1302 and a purifier 1303 sequentially connected and installed at the bottom of the water tank 2. The inlet end of the purifier 1303 is connected to a water pipe 1301 leading to the lower end of the cleaning tank 1. The second liquid pump 1302 is used to pump the cleaning liquid at the bottom of the cleaning tank 1 back to the water tank 2 through the water pipe 1301, and the purifier 1303 purifies the pumped-back cleaning liquid to achieve recycling of the cleaning liquid. The purifier 1303 is prior art and will not be explained in detail here.

[0051] In addition, such as Figure 1 As shown, in this embodiment, the top of the water tank 2 is provided with an injection port 14 for easy addition of cleaning fluid; a controller 15 is connected to one side of the cleaning tank 1. The controller 15 is electrically connected to the first liquid pump 6, the electric slide rail 8, the electric slider 9, the rotary motor 1105, the second liquid pump 1302 and the servo motor 16 through wires. The controller 15 is used to control the operation of the entire cleaning device, such as controlling the operation of the electric slide rail 8, the servo motor 16, the rotary motor 1105, the first liquid pump 6 and the second liquid pump 1302.

[0052] Among them, controller 15 can be a common PLC controller, etc.

[0053] Finally, it should be noted that the components involved in this utility model, such as the first liquid pump 6, electric slide rail 8, electric slider 9, rotary motor 1105, second liquid pump 1302, purifier 1303, controller 15, and servo motor 16, are all general standard parts or components known to those skilled in the art. Their structures and principles can be obtained by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0054] Working principle: First, place the analytical instrument on the fixed base 1101 and start the rotating motor 1105. The rotating motor 1105 drives the gear 1104 connected to it to rotate. Since the gear 1104 meshes with the lower half of the ring rack 1102, the ring rack 1102 begins to rotate. Then, the rotation of the ring rack 1102 drives the other gears 1104 that mesh with it to rotate, thereby causing the rack 1108 that meshes with the upper half of the gear 1104 to slide within the limiting groove 1106. The rack 1108 drives the moving plate 1109 to move. By adjusting the position of the moving plate 1109, the elastic rubber pad 1110 is made to fit tightly against the chemical analytical instrument, thus achieving a firm fixation of the instrument.

[0055] Then, the first liquid pump 6 is started. The first liquid pump 6 pumps the cleaning solution in the water tank 2 to the rotary spray head 5 through the connecting pipe 3 and the flow pipe 4. The rotary spray head 5 sprays and cleans the chemical analysis instrument. At the same time, the servo motor 16 is started. The servo motor 16 drives the turntable 12 to rotate, so that the instrument placed on the turntable 12 rotates accordingly, realizing all-round cleaning.

[0056] During the cleaning process, the electric slide rail 8 can be activated as needed, and the electric slider 9 can drive the support plate 10 to move, adjusting the position of the analytical instrument in the cleaning chamber 1 to ensure the cleaning effect.

[0057] During the cleaning process, the cleaning fluid gathers at the bottom of the cleaning tank 1. At this time, the second liquid pump 1302 can be started. The second liquid pump 1302 draws the cleaning fluid at the bottom of the cleaning tank 1 back to the water tank 2 through the water pipe 1301. During the return process, the purifier 1303 purifies the cleaning fluid. The purified cleaning fluid can be used for cleaning again.

[0058] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
