Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a colorimetric tube cleaning device. Background Technology

[0002] With the continuous improvement of medical water quality standards and the rapid development of online water quality monitoring technology, water quality analysis equipment is shifting from intermittent laboratory testing to high-frequency, high-reliability online continuous monitoring. In this context, the detection accuracy of key indicators such as total chlorine and hardness directly affects water safety. As a core component of optical detection, colorimetric tubes are in constant contact with water samples and reagents, and their inner walls are prone to accumulating sediment or crystals. If not cleaned thoroughly and promptly, this will lead to absorbance measurement drift, severely affecting the accuracy of optical detection methods such as DPD spectrophotometry. Therefore, the cleanliness of the colorimetric tube directly determines the accuracy of the measurement results.

[0003] A search revealed that Chinese patent application CN223288683U discloses a colorimetric tube cleaning device, which mainly uses a first mounting frame, a cleaning drive mechanism, a clamping component, a cleaning roller, a second mounting frame, and a slide to clean the colorimetric tube, thereby improving cleaning efficiency.

[0004] Compared with existing technologies in related fields, it can be seen that existing cleaning devices are cumbersome to adjust when cleaning colorimetric tubes of different sizes. The rigid cleaning method is prone to abrading the glass tube wall, reducing optical transmittance. In addition, cleaning dead corners are easy to occur during cleaning. After long-term operation, the deposits on the inner wall of the colorimetric tube need to be wiped off manually with cotton swabs, which affects the quality of cleaning. Utility Model Content

[0005] The purpose of this invention is to provide a colorimetric tube cleaning device to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A colorimetric tube cleaning device includes a cleaning tank, a liquid outlet valve at the lower end of the cleaning tank, a clamping unit and a displacement unit fixedly installed inside the cleaning tank, a cover plate rotatably installed at the upper end of the cleaning tank, and a cleaning unit fixedly installed on the displacement unit.

[0008] The cleaning unit includes a support frame and a liquid guiding valve assembly. The support frame is fixedly mounted on the displacement unit. A drive mechanism is fixedly mounted on the support frame. A mounting frame is fixedly mounted on the output shaft of the drive mechanism. A hydraulic telescopic mechanism is fixedly mounted on the mounting frame. A placement frame is fixedly mounted on the telescopic end of the hydraulic telescopic mechanism. The placement frame is slidably connected to the mounting frame. A second disc spring assembly and a spray pipe are arranged relatively fixedly on the placement frame. A brush mechanism is fixedly mounted on the second disc spring assembly. The spray pipe is located on both sides of the brush mechanism. The liquid guiding valve assembly is fixedly mounted inside the cleaning tank. The liquid guiding valve assembly is connected to the spray pipe through the drive mechanism, the mounting frame, and the placement frame.

[0009] Furthermore, a guide component is fixedly installed on the support frame, and a guide groove is provided on the mounting frame, with the guide component slidably connected to the guide groove.

[0010] Furthermore, the clamping unit includes a positioning groove and a first lead screw mechanism. The positioning groove and the first lead screw mechanism are located on the inner side of the cleaning tank. A negative pressure hole is provided in the positioning groove. The two ends of the first lead screw mechanism have opposite thread directions. Movable frames are installed on the two ends of the first lead screw mechanism through threaded engagement. Support rods are fixedly installed on the opposite sides of the two movable frames. A first disc spring assembly is fixedly installed on the telescopic end of the support rod. A pressure sensor is fixedly installed on the first disc spring assembly. A clamping component is fixedly installed on the pressure sensor.

[0011] Furthermore, anti-slip pads are fixedly installed in both the clamping parts and the positioning groove.

[0012] Furthermore, the displacement unit includes a second lead screw mechanism, which is fixedly installed inside the cleaning tank. A movable frame is installed on the second lead screw mechanism via a threaded connection, and the movable frame is fixedly connected to the support frame.

[0013] Furthermore, a bracket is fixedly installed on the mounting frame, and a displacement detection sensor is fixedly installed on the bracket, with the displacement detection sensor corresponding to the mounting frame.

[0014] Furthermore, an observation window is provided at the center of the cover plate.

[0015] The advantages compared to existing technologies are as follows:

[0016] 1. The hydraulic telescopic mechanism and placement frame enable the brush mechanism to adapt to the deviation of the tube wall thickness, allowing for rapid adjustment and adaptation according to the size of the colorimetric tube. This facilitates cleaning different colorimetric tubes and effectively improves the convenience and efficiency of adjustment. The second disc spring assembly allows the brush mechanism to flexibly adhere to the colorimetric tube wall, buffering the force on the tube wall during cleaning. This ensures effective contact cleaning with the brush mechanism while preventing excessive force from causing wear on the colorimetric tube, thus maintaining the optical transmittance of the colorimetric tube. The spray pipe forms a micro-flow jet and gas-liquid mixture to rinse the tube wall, effectively improving the removal effect of adhesive deposits. The displacement unit drives the brush mechanism to reciprocate, increasing the movement trajectory of the brush mechanism. The entire cleaning unit uses double-sided spraying and rotating brushing to cover and clean, effectively avoiding dead corners and ensuring the cleaning effect.

[0017] 2. The clamping component is driven by the first lead screw mechanism, the movable frame, and the first disc spring assembly to center and clamp the colorimetric tube, preventing the colorimetric tube from tilting. The first disc spring assembly allows the clamping component to flexibly contact the colorimetric tube, avoiding damage caused by hard impacts. The pressure sensor detects the clamping force, effectively improving the firmness and stability of clamping colorimetric tubes of different sizes, and preventing movement during the cleaning process, thus ensuring the cleaning quality and effect.

[0030] like Figures 1-9 As shown, a colorimetric tube cleaning device includes a cleaning tank 1. A discharge valve is provided at the lower end of the cleaning tank 1. A clamping unit and a displacement unit are fixedly installed inside the cleaning tank 1. A cover plate 2 is rotatably installed at the upper end of the cleaning tank 1. A cleaning unit is fixedly installed on the displacement unit. The discharge valve is connected to an external waste liquid recovery device. The colorimetric tube to be cleaned is placed into the cleaning tank 1. The colorimetric tube is clamped and fixed by the clamping unit. The cleaning tank 1 is closed by the cover plate 2 to effectively prevent the cleaning liquid from splashing and protect the environment. The cleaning unit is moved to the position of the colorimetric tube by the displacement unit. The colorimetric tube is cleaned by the cleaning unit. The cleaning waste liquid is discharged to the external waste liquid recovery device through the discharge valve to achieve rapid discharge of waste liquid.

[0031] like Figures 3-5 , Figure 7 , Figure 8As shown, the cleaning unit includes a support frame 401 and a liquid guiding valve assembly 411. The support frame 401 is fixedly mounted on the displacement unit. A drive mechanism 402 is fixedly mounted on the support frame 401. A mounting frame 403 is fixedly mounted on the output shaft of the drive mechanism 402. A hydraulic telescopic mechanism 404 is fixedly mounted on the mounting frame 403. A placement frame 405 is fixedly mounted on the telescopic end of the hydraulic telescopic mechanism 404. The placement frame 405 is slidably connected to the mounting frame 403. A second disc spring assembly 406 and a spray pipe 408 are arranged relatively fixedly on the placement frame 405. A brush mechanism 407 is fixedly mounted on the second disc spring assembly 406. The spray pipes 408 are located on both sides of the brush mechanism 407. The liquid guiding valve assembly 411... 1. Fixedly installed inside the cleaning tank 1, the liquid guiding valve assembly 411 is connected to the spray pipe 408 via the drive mechanism 402, mounting bracket 403, and placement bracket 405. The drive mechanism 402, hydraulic telescopic mechanism 404, brush mechanism 407, liquid guiding valve assembly 411, second disc spring assembly 406, and spray pipe 408 operate using existing technology. The liquid guiding valve assembly 411 is connected to an external hydraulic control device and a gas-liquid conveying device. According to the size of the colorimetric tube, the external hydraulic control device controls the hydraulic telescopic mechanism 404 to operate. The hydraulic telescopic mechanism 404 drives the placement bracket 405 to move. The placement bracket 405 drives the brush mechanism 407 to move via the second disc spring assembly 406. The brush mechanism 407 is adjusted. Position 07 aligns the center of the two brush mechanisms 407 with the wall of the colorimetric tube, allowing for quick adjustment and adaptation to different tube sizes. This facilitates cleaning different colorimetric tubes and significantly improves the convenience and efficiency of adjustment. After adjustment, the displacement unit moves the support frame 401, positioning the brush mechanism 407 at the colorimetric tube. The drive mechanism 402 then rotates the mounting frame 403. The mounting frame 403, via the hydraulic telescopic mechanism 404 and the placement frame 405, rotates the brush mechanism 407, the second disc spring assembly 406, and the spray pipe 408. The second disc spring assembly 406 flexibly attaches the brush mechanism 407 to the wall. The brush mechanism 407 adheres to the wall of the colorimetric tube, buffering the force on the tube wall during the cleaning process. This ensures that the brush mechanism 407 effectively adheres to the tube for cleaning while preventing excessive force from damaging the colorimetric tube. The gas-liquid conveying device delivers the liquid into the spray pipe 408 through the liquid guide valve group 411, drive mechanism 402, mounting frame 403, and placement frame 405. The liquid is then sprayed onto the colorimetric tube through the spray pipe 408, forming a micro-flow jet and gas-liquid mixture flushing on the tube wall. This effectively improves the removal effect of adhesive deposits. The brush mechanism 407 performs full-range cleaning on both the inner and outer walls of the colorimetric tube. The entire cleaning unit uses double-sided spraying and rotating brushing to cover and clean the tube, effectively avoiding dead corners and ensuring the cleaning effect.

[0032] like Figure 4As shown, a guide 409 is fixedly installed on the support frame 401, and a guide groove 410 is provided on the mounting frame 403. The guide 409 is slidably connected to the guide groove 410. The guide 409 and the guide groove 410 operate using existing technology. During the rotation of the mounting frame 403, the stability of the mounting frame 403 is improved by the guide 409 and the guide groove 410, and the deflection of the mounting frame 403 during the rotation is reduced.

[0033] like Figure 2 , Figure 3 , Figure 6 , Figure 9 As shown, the clamping unit includes a positioning groove 301 and a first lead screw mechanism 303. The positioning groove 301 and the first lead screw mechanism 303 are located on the inner side of the cleaning tank 1. A negative pressure hole 302 is provided in the positioning groove 301. The two ends of the first lead screw mechanism 303 have opposite thread directions. Movable frames 304 are installed on both ends of the first lead screw mechanism 303 through threaded engagement. Support rods 305 are fixedly installed on the opposite sides of the two movable frames 304. A first disc spring assembly 306 is fixedly installed on the telescopic end of the support rod 305. A pressure sensor 307 is fixedly mounted on the first disc spring assembly 306. A clamping member 308 is fixedly mounted on the pressure sensor 307. Anti-slip pads 309 are fixedly mounted in both the clamping member 308 and the positioning groove 301. The first lead screw mechanism 303, the first disc spring assembly 306, the pressure sensor 307, and the anti-slip pads 309 operate using existing technology. The negative pressure hole 302 is connected to an external negative pressure device. The bottom of the colorimetric tube is placed into the positioning groove 301, and the colorimetric tube is positioned by the positioning groove 301, facilitating placement. The colorimetric tube, according to its size, is moved by a first lead screw mechanism 303 driving a movable frame 304. The movable frame 304, via a support rod 305, a first disc spring assembly 306, and a pressure sensor 307, moves a clamping member 308. The clamping member 308 centers and clamps the colorimetric tube, preventing it from tilting. The first disc spring assembly 306 ensures that the clamping member 308 makes flexible contact with the colorimetric tube, preventing damage from hard impacts. The pressure sensor 307 detects the force applied to the colorimetric tube and adjusts the applied pressure based on the detection results. This ensures effective clamping and fixation of the colorimetric tube while preventing damage from excessive force. Simultaneously, an external negative pressure device uses a negative pressure hole 302 to adsorb and fix the bottom of the colorimetric tube, and an anti-slip pad 309 provides cushioning protection and increases friction for the colorimetric tube, effectively improving the firmness and stability of clamping colorimetric tubes of different sizes and preventing movement during cleaning, thus ensuring cleaning quality and effect.

[0034] like Figure 1 , Figure 3As shown, the displacement unit includes a second lead screw mechanism 501, which is fixedly installed inside the cleaning tank 1. A movable frame 502 is threadedly installed on the second lead screw mechanism 501, and the movable frame 502 is fixedly connected to the support frame 401. The second lead screw mechanism 501 operates using existing technology. After the colorimetric tube is clamped and fixed for cleaning, the second lead screw mechanism 501 drives the movable frame 502 to move, which in turn drives the support frame 401 to move, facilitating the entry of the brush mechanism 407 into the colorimetric tube for cleaning. Simultaneously, during the cleaning process, the second lead screw mechanism 501 and the movable frame 502 drive the brush mechanism 407 to reciprocate, increasing the movement trajectory of the brush mechanism 407, ensuring the cleaning effect, and avoiding dead angles.

[0035] like Figure 7 As shown, a bracket 6 is fixedly installed on the mounting frame 403, and a displacement detection sensor 7 is fixedly installed on the bracket 6. The displacement detection sensor 7 corresponds to the placement frame 405. The bracket 6 and the displacement detection sensor 7 operate using existing technology. The bracket 6 supports the displacement detection sensor 7. During the adjustment of the placement frame 405, the displacement detection sensor 7 detects the position of the placement frame 405 in real time, which facilitates precise control of the adjustment position of the placement frame 405, ensuring that the brush mechanism 407 can effectively contact and clean the tube wall of the colorimetric tube, and preventing the placement frame 405 from colliding with the colorimetric tube and causing damage to the colorimetric tube.

[0036] like Figure 9 As shown, an observation window 8 is provided at the center of the cover plate 2. The observation window 8 operates using existing technology. During the cleaning process, the staff can easily observe the cleaning status of the inner wall of the colorimetric tube through the observation window 8, and adjust the cleaning parameters in a timely manner.

[0037] Working principle: such as Figure 2 , Figure 3 , Figure 6 , Figure 9 As shown, the colorimetric tube is positioned by the positioning groove 301. The bottom of the colorimetric tube is placed into the positioning groove 301. According to the size of the colorimetric tube, the movable frame 304 is moved by the first lead screw mechanism 303. The movable frame 304 moves the clamping member 308 by the support rod 305, the first disc spring group 306, and the pressure sensor 307. The clamping member 308 centers and clamps the colorimetric tube. At the same time, the external negative pressure device adsorbs and fixes the bottom of the colorimetric tube through the negative pressure hole 302. The anti-slip pad 309 buffers and protects the colorimetric tube and increases friction. After the colorimetric tube is fixed, the cleaning box 1 is closed by the cover plate 2.

[0038] like Figure 4 , Figure 5 , Figure 7 , Figure 8As shown, the placement rack 405 is moved by the hydraulic telescopic mechanism 404, and the placement rack 405 moves the brush mechanism 407 by the second disc spring group 406. The position of the brush mechanism 407 is adjusted so that the center position of the two brush mechanisms 407 corresponds to the tube wall of the colorimetric tube. The position of the placement rack 405 is detected in real time by the displacement detection sensor 7, so as to facilitate precise control of the adjustment position of the placement rack 405.

[0039] like Figure 1 , Figure 3 As shown, the second lead screw mechanism 501 drives the moving frame 502 to move, and the moving frame 502 drives the support frame 401 to move, so that the brush mechanism 407 moves to the position of the colorimetric tube.

[0040] like Figure 2 , Figure 3 , Figure 6 , Figure 9 As shown, the mounting frame 403 is rotated by the drive mechanism 402. The mounting frame 403 rotates the brush mechanism 407, the second disc spring group 406, and the spray pipe 408 through the hydraulic telescopic mechanism 404 and the placement frame 405. The stability of the mounting frame 403 is improved by the guide member 409 and the guide groove 410. The gas-liquid conveying device conveys the liquid into the spray pipe 408 through the liquid guide valve group 411, the drive mechanism 402, the mounting frame 403, and the placement frame 405, and sprays it onto the colorimetric tube through the spray pipe 408, forming a micro-flow spray and gas-liquid mixture to rinse the tube wall. The brush mechanism 407 performs full-range cleaning of the inner and outer tube walls of the colorimetric tube. The second disc spring group 406 makes the brush mechanism 407 flexibly fit against the tube wall, buffering the force on the tube wall during the cleaning process, so as to ensure that the brush mechanism 407 can effectively fit and clean.

[0041] like Figure 1 , Figure 3 , Figure 9 As shown, during the cleaning process, staff can easily observe the cleaning status of the inner wall of the colorimetric tube through the observation window 8, and adjust the cleaning parameters in a timely manner. The second screw mechanism 501 and the moving frame 502 drive the brush mechanism 407 to move back and forth, increasing the movement trajectory of the brush mechanism 407 and ensuring that the colorimetric tube is cleaned in its entirety. The cleaning waste liquid is discharged to the external waste liquid recovery device through the outlet valve.
