Description

Technical Field

[0001] The utility model relates to the technical field of chemical instrument cleaning, in particular to a bottle washing machine. Background Art

[0002] Chemical analysis refers to the method of determining the chemical composition or composition of a substance. It can be divided into inorganic analysis and organic analysis according to the properties of the substance being analyzed. A large number of test tubes or reagent bottles are used in the chemical analysis process. Test tubes or reagent bottles are usually made of glass. Currently, the cleaning of test tubes or reagent bottles after use is done manually or in a single simple automatic cleaning station. This cleaning method is not only labor-intensive, but also has the problem of poor cleaning effect.

[0003] At present, the reagent residue cleaning agents commonly used in the market are mainly aqueous solutions and powders. However, for the convenience of transportation, for example, soda ash used to clean acidic reagent residues is transported and sold in powder form. In addition, in order to meet the cleaning needs of stubborn chemical stains, powders can be used to freely prepare cleaning solutions that match the concentration of the cleaning effect to improve the cleaning effect. Aqueous solutions are prone to oxidation and failure when left for a long time. Therefore, powders are widely used in reagent residue cleaning.

[0004] In chemical experiments, after the test tubes containing reactants have been subjected to high temperature or acid-base reactions, residues often adhere to the inner wall of the test tubes. Cleaning with water alone cannot completely clean them. Using a bottle washer can achieve the cleaning effect and greatly improve efficiency. In the prior art, the structure of the bottle washer includes a cleaning tank and a card plate disposed in the cleaning tank, the card plate is provided with a plurality of card holes, and a plurality of nozzles disposed above the card plate.

[0005] When the prior art is used, the powder is manually added into the test tube, and clean water is injected into the test tube through a nozzle. The powder is dissolved in the clean water to form a suspended mixed liquid. After soaking for a period of time, the mixed liquid dissolves the reagent residues on the inner wall of the test tube. However, due to the limited volume of clean water in the test tube, the amount of powder that can be dissolved is limited. If too little powder is added, it will not have a good cleaning effect. The amount of powder added manually will slightly exceed the standard usage amount, and the amount added cannot be accurately controlled. As a result, part of the powder cannot be dissolved and then precipitates at the bottom of the test tube; and in order to improve the cleaning effect, the soaking time is usually extended. The static placement during this period will cause part of the active ingredients of the powder to precipitate. At this time, manual stirring is required to dissolve the precipitated active ingredients in the clean water again, so as to continue to maintain the ability to remove the reagent residues; after the soaking is completed, the test tube is rinsed through the nozzle. Since the bottle mouth of the test tube is flushed upward, it cannot be rinsed thoroughly, thereby affecting the cleaning effect. Utility Model Content

[0006] The utility model aims to provide a bottle washing machine, which can provide a powder capable of stirring and precipitating, so that the precipitated powder can be redissolved in clean water, so as to improve the cleaning effect of reagent residues and avoid wasting the powder.

[0007] In order to achieve the above object, the utility model provides the following technical solutions:

[0008] A bottle washing machine comprises a cleaning tank, which is rotatably connected to a clamping plate, the cleaning tank is fixedly provided with a servo motor for driving the clamping plate to rotate, and the clamping plate is provided with a clamping hole; the cleaning tank is provided with a mounting plate located above the clamping plate, the cleaning tank is fixedly provided with a cylinder for driving the mounting plate to move, the mounting plate is fixedly provided with a first nozzle and a suction pipe aligned with the corresponding clamping hole, the bottom of the cleaning tank is provided with a second nozzle aligned with the clamping hole, the suction pipe is connected to a negative pressure pump, and the bottom of the suction pipe is located above the bottom of the first nozzle.

[0009] The working principle and beneficial effects of the utility model:

[0010] In this solution, since the servo motor has a self-locking function, the position of the clamping plate can be locked when the servo motor stops working so that it will not rotate. At this time, the clamping plate is in a horizontal state, and the test tube is clamped into the clamping hole. The mounting plate is located directly above the test tube, and the powder is added into the test tube respectively. The mounting plate is provided with a first nozzle and a suction tube aligned with the corresponding clamping hole, and the bottom of the cleaning tank is provided with a second nozzle aligned with the corresponding clamping hole. The mounting plate is driven downward by the cylinder so that the first nozzle and the suction tube at the bottom of the mounting plate are inserted into the test tube, and the first nozzle injects clean water into the test tube, and the clean water flushes the powder to dissolve it. The mounting plate is then driven upward by the cylinder so that the first nozzle and the suction tube are separated from the test tube, and the undissolved powder is precipitated at the bottom of the test tube.

[0011] After the inner wall of the test tube is soaked for a period of time, the powder has enough time to fully dissolve most of the reagent residues on the inner wall of the test tube, resulting in a reduction in the ability of the powder dissolved in the clean water to remove the reagent residues. The static placement during this period will also cause a part of the effective ingredients of the powder to precipitate, resulting in a reduction in the ability to remove the reagent residues. The mounting plate is driven downward by the cylinder to insert the first nozzle and the suction tube into the test tube. The bottom of the suction tube is located above the bottom of the first nozzle. The negative pressure pump is started to allow the suction tube to extract the liquid on the top layer of the test tube from the test tube, and then clean water is injected through the first nozzle. The clean water flushes the precipitated powder and effective ingredients and dissolves them again, and continues to remove the remaining reagent residues. After completing the above process several times, the servo motor drives the card plate to rotate toward the bottom of the cleaning tank, and the bottle mouth of the test tube is aligned with the multiple second nozzles at the bottom of the cleaning tank. The second nozzle sprays water to flush the inside of the test tube for thorough cleaning.

[0012] In this solution, the liquid in the test tube is sucked by the suction tube, so that there is enough space inside the test tube for the first nozzle to inject clean water, and the clean water will flush the precipitated powder and active ingredients to dissolve them again, so as to improve the utilization rate of the powder and the ability to remove reagent residues. In addition, the mouth of the test tube can be adjusted downward for flushing, and the flushing is thorough, thereby improving the cleaning effect.

[0013] Furthermore, the number of the card holes is multiple and evenly spaced on the card plate. This optimization solution can clean multiple test tubes and improve the cleaning efficiency.

[0014] Furthermore, the cleaning tank is provided with a drain valve, the negative pressure pump includes a water inlet and a water outlet, the suction pipe is connected to the water inlet, and the water outlet is connected to the cleaning tank. The negative pressure pump generates a suction force so that the suction pipe discharges the liquid in the test tube into the cleaning tank through the water outlet, and the liquid is discharged to the outside through the drain valve.

[0015] Furthermore, the clamping hole is fixedly sleeved with a rubber sleeve. When the test tube squeezes the rubber sleeve, the rubber sleeve deforms and clamps the test tube, thereby improving the fixing effect.

[0016] Furthermore, the water outlet of the first nozzle is downwardly directed, and the precipitated powder is directly flushed from the water outlet of the first nozzle to promote the re-dissolution of the powder. BRIEF DESCRIPTION OF THE DRAWINGS

In practice, if the corresponding structures are changed in the same direction based on the directions while keeping the relative positions unchanged, it will not affect the implementation of the plan.

[0024] Embodiment: This embodiment takes cleaning of the test tube 11 as an example, and can also be applied to cleaning of reagent bottles.

[0025] A bottle washing machine, such as Figure 1 As shown, the cleaning tank includes a cleaning tank, which is rotatably connected to an adjusting shaft 2, a driven gear is fixedly sleeved on the adjusting shaft 2, a clamping plate 12 is fixedly sleeved on the adjusting shaft 2, the clamping plate 12 is provided with 7 clamping holes, each of which is fixedly clamped with a test tube 11, and sufficient space is reserved in the cleaning tank for the clamping plate 12 and the 7 test tubes 11 to rotate.

[0026] The cleaning tank is fixed with a servo motor, and the active end of the servo motor is fixedly sleeved with a driving gear 1 meshing with a driven gear. The servo motor is a commonly used mechanical transmission part in the field, and has a self-locking function. It is a motor that can convert electrical signals into mechanical motions. It can rotate the active end of the motor to a desired position and maintain the position by controlling the current of the motor. Since the active end of the servo motor is fixedly sleeved with a driving gear 1 meshing with a driven gear, the driving gear 1 keeps the adjustment shaft 2 and the card plate 12 stationary through the driven gear. In this embodiment, the servo motor adopts a servo motor of model MZ751A200 produced by Nidec Corporation, which can provide a sufficiently large self-locking force.

[0027] The cleaning tank is provided with a mounting plate 4 located above the card plate 12, the cleaning tank is fixedly provided with a cylinder 3 for driving the mounting plate 4 to move, the mounting plate 4 is fixedly provided with a first nozzle 6 and a suction pipe 5 aligned with the corresponding card holes, the mounting plate 4 is also fixedly provided with a negative pressure pump 7 and a water pump 8, the input end of the negative pressure pump 7 is fixed and connected with a first connecting pipe 9, the first connecting pipe 9 and the 7 suction pipes 5 are fixed and connected, the output end of the water pump 8 is fixed and connected with a second connecting pipe 10, the second connecting pipe 10 and the 7 first nozzles 6 are fixed and connected, and the input end of the water pump 8 is connected to a water source, such as an indoor tap.

[0028] A second nozzle 13 aligned with the card hole is provided at the bottom of the cleaning tank. The water flow principle of the second nozzle 13 is the same as that of the first nozzle 6, which will not be repeated here. The bottom of the suction pipe 5 is located above the bottom of the first nozzle 6.

[0029] like Figure 2As shown, in this scheme, since the servo motor has a self-locking function, the position of the clamping plate 12 can be locked when the servo motor stops working, so that it will not rotate. At this time, the clamping plate 12 is in a horizontal state, the test tube 11 is clamped in the clamping hole, the mounting plate 4 is located directly above the test tube 11, and the powder is added into the test tube 11 respectively; the mounting plate 4 is provided with a first nozzle 6 and a suction pipe 5 aligned with the corresponding clamping hole, and the bottom of the cleaning tank is provided with a second nozzle 13 aligned with the corresponding clamping hole, and the mounting plate 4 is driven downward by the cylinder 3 to make the first nozzle 6 and the suction pipe 5 at the bottom of the mounting plate 4 inserted into the test tube 11, the water pump 8 pressurizes water toward the second connecting pipe 10, and then injects clean water into the test tube 11 through the first nozzle 6, the clean water flushes the powder to dissolve it, and then the mounting plate 4 is driven upward by the cylinder 3 to make the first nozzle 6 and the suction pipe 5 separate from the test tube 11, and the undissolved powder is precipitated at the bottom of the test tube 11.

[0030] like Figure 3 and Figure 4 As shown, after the inner wall of the test tube 11 is soaked for a period of time, the dissolved powder has enough time to fully remove most of the reagent residues on the inner wall of the test tube 11, resulting in a reduced ability of the powder dissolved in the clean water to remove the reagent residues. In addition, this long period of static placement will also cause a portion of the effective ingredients of the powder to precipitate, resulting in a reduced ability to remove the reagent residues. The mounting plate 4 is driven downward by the cylinder 3 to insert the first nozzle 6 and the suction tube 5 into the test tube 11, and the bottom of the suction tube 5 is located above the bottom of the first nozzle 6. The negative pressure pump 7 is started to generate suction between the first connecting tube 9 and the suction tube 5. The suction tube 5 draws the liquid on the top layer of the test tube 11 away from the test tube 11, and then pressurizes and sprays clean water into it through the first nozzle 6. The impact force of the clean water washes the precipitated powder and effective ingredients and dissolves them again, and continues to remove the remaining reagent residues. After completing the above process several times, the servo motor drives the card plate 12 to rotate toward the bottom of the cleaning tank, and the bottle mouth of the test tube 11 is aligned with the multiple second nozzles 13 at the bottom of the cleaning tank. The second nozzles 13 spray water to flush the inside of the test tube 11 for thorough cleaning.

[0031] In this solution, the liquid in the test tube 11 is sucked by the suction tube 5, so that there is enough space inside the test tube 11, so that the first nozzle 6 can spray clean water, and the clean water will flush the precipitated powder and active ingredients to dissolve them again, so as to improve the utilization rate of the powder and the ability to remove reagent residues. In addition, the mouth of the test tube 11 can be adjusted downward for flushing, and the flushing is thorough, thereby improving the cleaning effect.
