Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for food safety testing laboratories, and more specifically, to a condenser tube cleaning device for sulfur dioxide testing. Background Art

[0002] A condenser is a laboratory device used to promote condensation. It consists of an inner tube and an outer sleeve, available in straight, spherical, and serpentine shapes. The outer tube, which carries condensing water and features an inlet and outlet, facilitates condensation or reflux. The operating principle is based on heat exchange, with the cooling water in the outer tube exchanging heat with the airflow from the distillation flask, thereby cooling the airflow.

[0003] Currently, in food safety testing laboratories, a sulfur dioxide distiller comprises multiple distillation apparatuses, namely, multiple distillation flasks and multiple condensers. During pre-treatment experiments for sulfur dioxide testing, sample residue or residual liquid often enters the condenser through the distillation airflow from the distillation flask, clinging to the inner tube wall. If not cleaned promptly after the experiment, the accuracy of the next test result will be affected.

[0004] Currently, a common practice for cleaning the inner tube wall of a condenser is to dismantle multiple sets of distillation apparatuses and clean the inner tubes of the condenser one by one with a test tube brush. This is not only time-consuming and labor-intensive, but also consumes a lot of cleaning fluid and causes serious environmental pollution. Utility Model Content

[0005] In order to overcome the problems of time-consuming and labor-intensive cleaning of the inner tube of the condenser tube after sulfur dioxide detection and high consumption of cleaning liquid, the utility model provides a condenser tube cleaning device for sulfur dioxide detection.

[0015] a washing liquid barrel, wherein the washing liquid barrel contains washing liquid;

[0016] A water pump is placed in the washing liquid barrel, and the water pump is connected to the cleaning pipe through the drainage pipe and the adapter assembly.

[0017] The present invention according to the above solution further comprises a distillation device, which is connected to the outlet of the inner tube of the condenser.

[0018] According to the above solution of the present invention, the distillation apparatus is a round-bottom flask.

[0031] It's important to note that in food safety testing laboratories, a sulfur dioxide distiller consists of multiple distillation units, namely, multiple distillation flasks and multiple condensers. During pre-treatment experiments for sulfur dioxide testing, sample residue or residual nightshade often enters the condenser through the distillation airflow from the distillation flask, clinging to the inner tube wall. If not cleaned promptly after the experiment, the accuracy of the next test result will be affected.

[0032] At present, the common practice for cleaning the inner tubes of condensers is to dismantle all the distillation devices and clean the inner tubes of the condensers one by one with a test tube brush. This is not only time-consuming and labor-intensive, but also consumes a lot of cleaning fluid and causes great pollution to the environment.

[0033] like Figure 1-Figure 2 As shown, this embodiment provides a condenser tube cleaning device for sulfur dioxide detection. A cleaning tube 8 is mounted on a condenser tube 9 via a movable member 7. After drainage through a drainage tube 11, water is sprayed through a water outlet 81 of the cleaning tube 8 to clean the inner tube wall of the condenser tube 9. This avoids the time-consuming and labor-intensive manual cleaning of the condenser tube 9 required by conventional techniques by disassembling the entire distillation apparatus. Multiple cleaning tubes 8 can be connected in series to simultaneously clean multiple condenser tubes 9, saving time.

[0034] Specifically, the condenser tube cleaning device for sulfur dioxide detection includes a multi-connected cleaning device, which includes a plurality of cleaning tubes 8 and a switching assembly, and adjacent cleaning tubes 8 are connected through the switching assembly.

[0035] The upper end of each cleaning pipe 8 is sleeved with a movable part 7, which connects the cleaning pipe 8 and the condenser pipe 9. The lower end of the cleaning pipe 8 is provided with multiple water outlets 81, and the lower end of the cleaning pipe 8 is placed in the inner tube of the condenser pipe 9.

[0036] It also includes a drainage tube 11 , one end of which is connected to the external cleaning fluid, and the other end of which is connected to the plurality of cleaning tubes 8 .

[0037] In one embodiment, the adapter assembly includes an adapter and a connecting pipe 3, and the connecting pipe 3 connects the adapter and the cleaning pipe 8. Multiple cleaning pipes 8 are connected in series through the connecting pipe 3 and the adapter, and multiple condenser tubes 9 can be cleaned at the same time. Preferably, the adapter is a three-way joint 4 or a two-way joint 6. Specifically, the cleaning pipe 8 on the condenser tube 9 located at the edge is connected to the cleaning pipe 8 on the internal condenser tube 9 through the two-way joint 6, and the cleaning pipe 8 on the condenser tube 9 located in the middle position is connected to the cleaning pipe 8 on the adjacent internal condenser tube 9 through the three-way joint 4.

[0038] Preferably, the adapter assembly further includes a water-stop clamp 5 , the connecting pipe 3 is a hose, and the water-stop clamp 5 can be detachably clamped on the connecting pipe 3 . The provision of the water-stop clamp 5 facilitates control of the number of condenser tubes 9 that are cleaned simultaneously.

[0039] In one embodiment, the condenser tube cleaning device for sulfur dioxide detection further includes a liquid extraction device, which includes a washing liquid bucket 1 and a water pump 2. The washing liquid bucket 1 contains washing liquid; the water pump 2 is placed in the washing liquid bucket 1 and is connected to the washing pipe 8 via a drainage pipe 11 and an adapter assembly. Specifically, the water pump 2 is connected to the washing pipe 8 via the drainage pipe 11 and the three-way joint 4. The water pump 2 extracts the washing liquid from the washing liquid bucket 1, passes through the interior of the washing pipe 8, and then sprays it out from the water outlet 81 at the lower end of the washing pipe 8 to clean the inner tube wall of the condenser tube 9.

[0040] In one embodiment, the condenser tube cleaning device for sulfur dioxide detection further includes a distillation apparatus connected to the outlet of the inner tube of condenser tube 9. The distillation apparatus is a round-bottom flask 10. The cleaning liquid used to clean condenser tube 9 flows along the inner tube wall of condenser tube 9 and is collected in round-bottom flask 10. This liquid can also be used to clean round-bottom flask 10, thereby conserving cleaning liquid and reducing environmental pollution caused by the cleaning liquid.

[0041] When using, follow Figure 1 As shown, the device is connected in the order of left first, then right, and then bottom first, then top. Then, the water pump 2 switch is turned on to clean the inner tube walls of multiple condenser tubes 9.

[0042] In one embodiment, the cleaning tube 8 is made of a highly transparent material, such as glass, PVC, or PP, to facilitate observation of the flow of cleaning liquid within the cleaning tube 8 and to determine the cleaning effect. The cleaning tube 8 is designed with a smooth flow channel to reduce resistance to liquid flow and prevent clogging. The water outlets 81 provided at the lower end of the cleaning tube 8 are evenly arranged or staggered. The water outlets 81 are small circular holes to ensure that the cleaning liquid can fully cover the inner wall of the condenser tube 9, achieving a deep cleaning effect.

[0043] In one embodiment, the connecting tube 3 and movable member 7 are made of rubber. As the connecting component between the cleaning tube 8 and the condenser tube 9, the connecting tube 3 plays a crucial role. It ensures smooth transfer of cleaning fluid from the pump 2 to the condenser tube 9. The rubber connecting tube 3, with its excellent flexibility, corrosion resistance, and sealing properties, ensures a smooth cleaning process and maximizes cleaning effectiveness.

[0044] Preferably, the movable part 7 is a rubber plug, which can stably set the cleaning tube 8 at the upper end of the condenser tube 9.
