A low-damage test tube cleaning and drying device

Abstract

The invention relates to a low-damage test tube cleaning and drying device applied to the field of test tube cleaning and drying. The device controls the extended length of adjustable bristles on a brush assembly and gradually extends the bristles at a relatively short length in the initial stage of cleaning, so that the bristles are not easily entangled with larger impurities.

In the cleaning process, the test tube body can be repeatedly moved up and down and the adjustable sleeve can be driven to move synchronously, so that the adjustable bristles are repeatedly extended and shortened, thereby reducing the cleaning dead angle of the inner wall of the test tube body during the cleaning process, thereby improving the cleaning efficiency of the inner wall of the test tube body and reducing the situation in which impurity particles generated during the cleaning process are entangled in the bristles and damage the inner wall of the test tube body. The blown hot air enters the hot air circulation cylinder through a pipeline, and the hot air is recycled to save energy.

Description

Technical Field

[0001] The invention relates to the technical field of test tube cleaning and drying, and in particular to a low-damage test tube cleaning and drying device. Background Art

[0002] Test tubes are commonly used instruments in chemical laboratories. They are used as reaction containers for small amounts of reagents and are used at room temperature or when heated (they should be preheated before heating, otherwise the test tubes are prone to bursting). Test tubes are divided into ordinary test tubes, support test tubes, centrifugal test tubes, etc.

[0003] Test tubes are commonly used equipment in chemical experiments or inspections. Test tubes need to be cleaned in time after use. When cleaning the test tubes, the outer wall of the test tube can be easily cleaned by using a brush or an ultrasonic cleaner with a cleaning solution; as for the inner wall of the test tube, since the test tube is relatively long and the opening is small, it is very inconvenient to clean. In order to improve efficiency, an automatically rotating long-handled brush is used to clean the inner wall of the test tube. In order to achieve a better cleaning effect, the bristles of the brush are usually longer, so that the front end of the bristles is against the inner wall of the test tube for cleaning, which will cause the front end of the bristles to bend and intertwine with each other, causing impurities washed out by the bristles to enter the bent and intertwined bristles, and the impurities will remain in the bristles, causing secondary pollution and scratches to the test tubes cleaned later; the cleaned test tubes are quickly dried by hot air, but the hot air cannot effectively enter the longer test tubes for drying, and the low drying efficiency leads to high energy consumption. Summary of the invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the front ends of the bristles are bent and intertwined with each other, causing impurities washed out by the bristles to enter the bent and intertwined bristles, and the impurities will remain in the bristles, causing secondary pollution and scratches to the test tubes cleaned later; the cleaned test tubes are quickly dried by hot air, but the hot air cannot effectively enter the interior of the longer test tubes for drying, and the drying efficiency is low, resulting in high energy consumption.

[0032] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1-Figure 7 A low-damage test tube cleaning and drying device is shown, which includes: a cleaning chamber 1, a water tank chamber 3 and a hot air circulation chamber 2. A placement opening 4 is opened on the side wall of the cleaning chamber 1, which is convenient for taking the test tube body 8 to be cleaned and the test tube body 8 that has been cleaned through the placement opening 4. A main shaft 15 is rotatably connected to the middle of the cleaning chamber 1, and a rotating disk 10 rotatably connected to the cleaning chamber 1 is fixedly connected to the bottom of the main shaft 15. A driving ring 12 is arranged on the outer ring of the main shaft 15, and a plurality of movable bases 20 vertically plugged with the rotating disk 10 are arranged around the outer ring of the driving ring 12. The top is rotatably connected to a synchronous chassis 11 in contact with the outer wall of a driving ring 12. The main shaft 15 is used to control the rotating disk 10 to rotate in the inner cavity of the cleaning chamber 1, thereby driving the movable base 20 on the rotating disk 10 to move along the circumferential direction of the cleaning chamber 1, and synchronously driving the synchronous chassis 11 to move. The synchronous chassis 11 can be driven to rotate by controlling the rotation of the driving ring 12, so that the synchronous chassis 11 rotates on itself and revolves along the circumferential direction of the cleaning chamber 1 at the same time. Since the movable base 20 is vertically plugged into the rotating disk 10, the movable base 20 and the synchronous chassis 11 can move in the vertical direction.

[0035] It is worth mentioning that see Figure 5-Figure 7A brush assembly 9 is provided on each synchronous chassis 11. The brush assembly 9 includes a central control tube 22 that penetrates the synchronous chassis 11 and the driving ring 12 and is fixed to the rotating disk 10, a plurality of adjustable bristles 24 fixed to the outer ring of the central control tube 22, and an adjustable sleeve 23 sleeved on the outer ring of the central control tube 22. The adjustable bristles 24 penetrate the outer wall of the adjustable sleeve 23 in an inclined upward direction. A plurality of through holes 25 are provided on the top of the central control tube 22. Since the adjustable bristles 24 fixed on the outer wall of the central control tube 22 penetrate the outer wall of the adjustable sleeve 23 in an inclined direction, the adjustable bristles 24 on the outer wall of the adjustable sleeve 23 are inclined in the inner cavity of the test tube body 8. At this time, the adjustable bristles 24 are deployed in the inner cavity of the test tube body 8 in a shorter length. When the position of the adjustable sleeve 23 relative to the central control tube 22 is controlled separately, the adjustable bristles 24 on the outer wall of the adjustable sleeve 23 are tilted. When moving downward, the distance that the adjustable bristles 24 extend to the outside of the adjustable sleeve 23 gradually becomes longer, and the adjustable bristles 24 can be controlled to gradually approach the inner wall of the test tube body 8 and gradually fit the inner wall of the test tube body 8. Therefore, the length of the adjustable bristles 24 extending to the inner cavity of the test tube body 8 can be controlled by vertically moving the adjustable sleeve 23. The synchronous chassis 11 and the movable base 20 at the bottom are driven downward by pressing the test tube body 8. At this time, the adjustable sleeve 23 is driven downward synchronously. Since the central control tube 22 is fixed to the rotating disk 10, the adjustable sleeve 23 and the movable base 20 can be controlled to be misaligned and move downward. A diversion channel corresponding to the central control tube 22 is opened at the lower end of the cleaning chamber 1. The hollow central control tube 22 can pass cleaning liquid or hot air to clean and dry the inner wall of the test tube body 8.

[0036] Through the above-mentioned structural design, when the test tube body 8 is inserted into the brush assembly 9, in the initial stage of cleaning, more impurities will remain on the inner wall of the test tube body 8, which are easily wrapped by the traditional longer curved and interwoven bristles. At this time, the adjustable sleeve 23 is driven to move downward synchronously by controlling the downward pressure distance of the test tube body 8, and the adjustable bristles 24 are controlled to gradually extend out with a relatively short length, so that the larger impurities on the inner wall of the test tube body 8 can be initially washed. At this time, the end of the adjustable bristle 24 and the inner wall of the test tube body 8 have a larger movable space, and the larger impurities are also easy to fall to the bottom, avoiding being entangled by the adjustable bristles 24; during the gradual cleaning During the cleaning process, the test tube body 8 drives the adjustable sleeve 23 to move downward continuously and synchronously, so that the end of the adjustable bristle 24 is gradually extended and more closely fits the inner wall of the test tube body 8, thereby increasing the cleaning intensity. In addition, the test tube body 8 can be repeatedly moved up and down during the cleaning process, driving the adjustable sleeve 23 to move synchronously, so that the adjustable bristles 24 are repeatedly extended and shortened, thereby reducing the cleaning dead corners of the inner wall of the test tube body 8 during the cleaning process. This not only improves the cleaning efficiency of the inner wall of the test tube body 8, but also reduces the situation where the impurity particles generated during the cleaning process are entangled in the bristles and cause damage to the inner wall of the test tube body 8.

[0037] In this embodiment, a clean water tank and a clean water pipe 16 connected to the clean water tank are provided in the water tank chamber 3. The clean water pipe 16 is connected to the diversion channel. The clean water tank is equipped with a water pump. The water pump draws water into the clean water pipe 16, and enters the diversion channel through the clean water pipe 16, and enters the inner cavity of the central control tube 22 through the diversion channel, inputs the cleaning liquid or clean water into the inner cavity of the central control tube 22, and is discharged through the top through hole 25 of the central control tube 22 to rinse and clean the inner wall of the test tube body 8.

[0038] In addition, a hot air circulation cylinder 17 and a circulation pump 19 are provided in the hot air circulation chamber 2. The input end of the circulation pump 19 is connected to the inner cavity of the hot air circulation cylinder 17. The input end of the hot air circulation cylinder 17 is connected to the inner cavity of the cleaning chamber 1 through a pipeline. The output end of the circulation pump 19 is connected to the diversion channel through a drying air duct 18. The circulation pump 19 inputs the hot air in the hot air circulation cylinder 17 into the diversion channel through the drying air duct 18 and inputs it into the inner cavity of the central control pipe 22. When the cleaned test tube body 8 is dried, the hot air can be quickly input to The residual moisture in the inner cavity of the test tube body 8 is blown out from top to bottom to improve the drying efficiency, and the blown hot air enters the hot air circulation cylinder 17 through the pipe, and the hot air is recycled to save energy. A gap is provided between the drying air duct 18 and the cleaning water pipe 16 on the diversion channel, and the bottom opening of the central control pipe 22 moves along the diversion channel, and passes through the drying air duct 18 and the cleaning water pipe 16 in turn, and the cleaning liquid and hot air are input into the test tube body 8 in turn, and the test tube body 8 is automatically cleaned, rinsed and dried.

[0039] In this implementation, see Figure 4-Figure 5 The main shaft 15 is installed on the rotating shaft of the driving member 15, and the driving member 2 is installed on the main shaft 15. The output end of the driving member 2 is installed with a gear ring meshing with the inner ring of the driving ring 12. The main shaft 15 is driven to rotate by the driving member 15, and the rotating disk 10 is driven to rotate synchronously, and at the same time, the brush assembly 9 and the test tube body 8 located on the synchronous chassis 11 are driven to move along the circumferential direction of the cleaning chamber 1, so that they automatically enter the cleaning and drying processes in turn, and the driving ring 12 is driven to rotate by the driving member 2, which can synchronously drive the synchronous chassis 11 and the test tube body 8 to rotate, and the test tube body 8 rotates and forms a relative motion with the brush assembly 9, so that the inner wall of the rotating test tube body 8 is cleaned by the bristles.

[0040] Also, see Figure 2-Figure 4A positioning pressure rod 7 is provided at the top of each brush assembly 9, and the outer ring of the positioning pressure rod 7 is provided with a guide ring 6. One side of the guide ring 6 is hinged to the outer wall of the main shaft 15 through a connecting plate, and a limiting plate 13 fixed to the main shaft 15 is provided below the guide ring 6. The front end of the limiting plate 13 is provided with a slot matching the positioning pressure rod 7. The top of the test tube body 8 is limited by the positioning pressure rod 7. The front end of the limiting plate 13 can limit the position of the positioning pressure rod 7 so that it can stably press down the top of the test tube body 8, and when the test tube body 8 moves to the placement port 4, the positioning pressure rod 7 can be pulled to drive the guide ring 6 to swing, and the limit on the top of the test tube body 8 can be released, so that the cleaned test tube body 8 can be taken out and the test tube body 8 to be cleaned can be loaded.

[0041] In this implementation, see Figure 7-Figure 8 A return spring 27 is installed at the bottom of the movable base 20, so that after the test tube body 8 drives the synchronous chassis 11 and the movable base 20 to move downward, the elastic force can be used to push them upward. A track ring 14 corresponding to the moving track of the guide ring 6 is fixed to the top of the inner cavity of the cleaning chamber 1. A guide protrusion 28 is arranged at the bottom of the track ring 14. The guide protrusion 28 is a structure that gradually protrudes along the moving track direction of the guide ring 6. During the synchronous movement of the test tube body 8 and the guide ring 6, the top of the guide ring 6 moves along the track ring 14 and passes through the track ring 14. When the guide ring 6 passes through the guide protrusion 28, it will gradually be pushed downward by the guide protrusion 28, thereby achieving the purpose of controlling the downward movement of the test tube body 8, thereby synchronously controlling the adjustable bristles 24 to gradually extend. In addition, the guide protrusion 28 can be provided with a multi-section protruding corrugated structure, which can enable the test tube body 8 to move up and down synchronously during the movement, thereby driving the adjustable sleeve 23 to move synchronously through the test tube body 8, so that the adjustable bristles 24 are repeatedly extended and shortened, reducing the cleaning dead corners of the inner wall of the test tube body 8.

[0042] Also, see Figure 7 The top of the synchronous chassis 11 is a concave structure, and a plurality of collecting grooves 21 are vertically penetrated on the synchronous chassis 11. A collecting pipe 26 is provided at the bottom of the movable base 20 and penetrates to the bottom of the rotating disk 10. A receiving groove corresponding to the collecting groove 21 is opened on the top of the movable base 20. The top of the collecting pipe 26 is connected with the receiving groove. The cleaning liquid or hot air flowing in through the central control pipe 22 enters the synchronous chassis 11 through the test tube body 8, and will be collected by the collecting groove 21 on the synchronous chassis 11, and gradually enter the collecting pipe 26 through the receiving groove. The liquid or hot air is recovered through the collecting pipe 26, and the hot air can be recycled to save energy.

[0043] The second implementation method:

[0044] Figure 8-Figure 10As shown, unlike the first embodiment, in order to realize automatic cleaning and drying of the test tube body 8, the following technical scheme is additionally provided: a limiting ring 29 and a limiting ring 30 corresponding to the central control tube 22 and the collecting tube 26 are respectively arranged around the bottom of the rotating disk 10; a limiting groove 31 corresponding to the limiting ring 29 and a limiting groove 32 corresponding to the limiting ring 30 are provided on the cleaning chamber 1; a diversion channel is provided on the cleaning water tank 33; when the rotating disk 10 rotates, the limiting ring 29 and the limiting ring 30 at the bottom of the rotating disk 10 slide along the limiting groove 31 and the limiting groove 32 on the cleaning chamber 1, and the central control tube 22 located on the limiting ring 29 passes through the diversion channel and is connected with the corresponding cleaning liquid, flushing liquid and hot air in turn.

[0045] It is worth mentioning that the diversion channel includes a cleaning water tank 33 and a flushing water tank 35. The diversion channel is opened on the cleaning water tank 33, and the cleaning water tank 33 and the flushing water tank 35 are opened in sequence along the moving trajectory of the guide ring 6. The cleaning water tank in the water tank chamber 3 is divided into a cleaning liquid tank and a clean water tank. The cleaning liquid tank is connected to the inner cavity of the cleaning water tank 33 through a pipeline, and the clean water tank is connected to the inner cavity of the flushing water tank 35 through a pipeline. A water recovery tank 34 is opened on the limiting groove 32 at the corresponding position of the cleaning water tank 33 and the flushing water tank 35. The clean water tank in the water tank chamber 3 also includes a sewage collection tank, which is connected to the water recovery tank 34 through a pipeline. Two guide protrusions 28 are provided, one of which is fixed on the track ring 14 at the corresponding position of the cleaning water tank 33, and the other is fixed It is fixed on the track ring 14 at a position corresponding to the water recovery groove 34. Since the limit ring 1 29 and the limit ring 2 30 slide along the corresponding limit groove 1 31 and the limit groove 2 32, when the central control tube 22 moves to the position corresponding to the cleaning water groove 33 and moves along the cleaning water groove 33, the cleaning liquid in the cleaning liquid tank will enter the central control tube 22 through the cleaning water groove 33, and the cleaning liquid will be sprayed into the inner wall of the test tube body 8 to clean the test tube body 8. In addition, when the central control tube 22 moves along the cleaning water groove 33, the guide ring 6 on the top of the test tube body 8 moves along the guide protrusion 28. Therefore, when the central control tube 22 sprays the cleaning liquid, the test tube body 8 moves in the vertical direction, thereby controlling the adjustable bristles 24 to clean the inner wall of the test tube body 8, thereby improving the cleaning efficiency.

[0046] In addition, similarly, when the central control pipe 22 passes through the flushing sink 35, the test tube body 8 needs to be rinsed with clean water after cleaning. The clean water in the clean water tank will enter the test tube body 8 through the flushing sink 35 to rinse the inner wall of the test tube body 8, and the adjustable bristles 24 that can be extended and shortened can quickly clean the inner wall of the test tube body 8 to improve the flushing efficiency.

[0047] The sewage in the washing process will enter the collection pipe 26 through the synchronous chassis 11, and enter the sewage tank through the water recovery tank 34, and the cleaned sewage will be collected and processed to avoid polluting the environment.

[0048] In the present embodiment, the shunt channel further includes a drying air slot 36 and a hot air recovery slot 37. The drying air slot 36 is provided on the limiting slot 1 31 and is located at a downstream position of the flushing water slot 35. The hot air recovery slot 37 is provided on the limiting slot 2 32 and is located at a position corresponding to the drying air slot 36. The hot air recovery slot 37 is connected to the drying air duct 18 through a pipeline. The limiting slot 2 32 is provided with a hot air recovery slot 37 at a position corresponding to the drying air slot 36. The hot air recovery slot 37 is connected to the input end of the hot air circulation cylinder 17 through a pipeline. After the inner wall of the test tube body 8 is washed and rinsed, when it needs to be dried by circulating hot air, the central control pipe 22 enters the drying air slot 36, and the circulating hot air passes through the drying air duct 18. It enters the drying air slot 36 and enters the inner wall of the test tube body 8 through the central control pipe 22, and blows and dries the water stains remaining on the inner wall of the test tube body 8 from top to bottom, which can dry the inner wall of the test tube body 8 and greatly improve the drying efficiency. The hot air blown out by the drying enters the hot air recovery slot 37 through the collecting pipe 26, and is recovered into the hot air circulation cylinder 17 by the hot air recovery slot 37. The hot air is recovered and recycled through the hot air circulation cylinder 17 to save energy. When the inner wall of the test tube body 8 is dried by hot air, the water recovery slot 34 is controlled to be shortened, and a gap is formed between the end of the water recovery slot 34 and the inner wall of the test tube body 8, so that the hot air can quickly flow through the inner wall of the test tube body 8, thereby improving the hot air drying efficiency.

[0049] In addition, the cleaning water tank 33, the water recovery tank 34, the rinsing water tank 35, the drying air tank 36 and the hot air recovery tank 37 are all long arc-shaped structures, so that during the cleaning, rinsing and drying process of the test tube body 8, the corresponding cleaning liquid, clean water and hot air always enter the inner wall of the test tube body 8 while the test tube body 8 moves, and automatically cleans and dries it. The inner cavity of the hot air circulation cylinder 17 is installed with a heating module to always maintain the hot air inside the hot air circulation cylinder 17 at a suitable temperature to improve the drying efficiency of the circulating hot air. The input end of the hot air circulation cylinder 17 is located at its bottom, and the output end of the hot air circulation cylinder 17 is located at its top. A drain valve is provided at the bottom of the hot air circulation cylinder 17. The hot air collected by the collection pipe 26 contains a certain amount of moisture, which will remain at the bottom of the hot air circulation cylinder 17 and be discharged regularly through the drain valve to reduce the humidity of the hot air and improve the drying efficiency.

[0050] The heating module is a common component in the prior art, such as an air heater, which is used to heat the air and maintain the set temperature. It is well known to personnel in this technical field and is prior art. It is not within the protection scope of this technical solution. The specific working principle of this application will not be described in detail in the technical solution.

[0051] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
