Although this technology can realize the cleaning of the pipe wall, it still requires the operation of workers, is inconvenient to use, and the cleaning effect is not good. Summary of the Utility Model

[0004] The utility model aims to overcome at least one defect of the above prior art, and provides a pipeline cleaning device to achieve the purpose of simple structure and high cleaning efficiency.

[0005] The utility model provides a pipeline cleaning device, which includes a driving mechanism, a waste liquid collection buffer bottle, a first connecting pipe, a functional pipe, a second connecting pipe, and one set or multiple sets of lotion bottle groups connected in parallel in sequence; a spectrophotometric detection box is installed on the first connecting pipe; a cleaning box assembly is arranged below the functional pipe; it is judged whether the cleaning is completed according to the change of the absorbance on the first connecting pipe detected by the spectrophotometric detection box.

[0006] The driving mechanism is a pressure pump, which is connected to the waste liquid collection buffer bottle through a pipeline. The liquid outlet of the first connecting pipe is inserted into the bottom of the waste liquid collection buffer bottle, and the liquid inlet of the pipeline connected to the pressure pump is arranged below the opening of the waste liquid collection buffer bottle and is higher than the liquid outlet of the first connecting pipe. Using negative pressure, the detergent in a set of detergent bottles is pumped into the functional tube. When the spectrophotometric detection box detects a change in the absorbance on the first connecting pipe, it indicates that the functional tube is filled with detergent. At this time, the pump body is turned off, and the cleaning box assembly is started to clean the functional tube. Different washing times can be set according to different functional tubes. After the set washing time is completed, the valve of the first set of detergent bottles can be closed. If multiple cleaning agents are required, the valve of the second set of detergent bottles can be opened in the same way, and so on. When the absorbance of the first connecting pipe is close to the absorbance of the last detergent, it indicates that the cleaning is completed. At this time, the valve of the last set of detergent bottles is closed, and the pressure pump is started to evacuate the waste liquid.

[0007] Further, a heater is also connected to the end of the second connecting pipe; after the cleaning of the functional tube is completed, the external air is heated by the heater and then transported to the functional tube to achieve drying of the functional tube.

[0008] Since there is still residual organic solvent in the functional tube after cleaning, it can volatilize naturally. Preferably, the present invention designs a heater. By starting the pressure pump, at this time, the external air enters the entire pipeline system after being heated by the heater, and the entire pipeline system can be dried.

[0009] Preferably, the functional tube targeted by the present invention is a viscosity tube or a glass tube.

[0010] Further, the spectrophotometric detection box includes a box body, a light source, and a detector; the first connecting pipe passes through the box body; the light source and the detector are arranged opposite to each other, and the connection line between the two passes through the first connecting pipe.

[0011] Further, the cleaning box assembly includes an ultrasonic cleaning box and a heating source; the heating source is arranged at the bottom of the ultrasonic cleaning box. It can heat the water in the ultrasonic cleaning box to improve the cleaning efficiency. The ultrasonic cleaning box is filled with water as the ultrasonic medium, and the heating source can heat the water in the ultrasonic cleaning box to achieve water bath heating of the detergent in the functional tube.

[0012] Further, a storage rack is also arranged above the ultrasonic cleaning box. The storage rack is used to fix the functional tube. The cleaning box assembly also includes a temperature probe. The top of the temperature probe is fixed on the storage rack, and the other end extends into the ultrasonic cleaning box.

In addition, through the built-in algorithms and programs of the controller, relevant parameters of the spectrophotometric detection box can be pre-designed, so that the spectrophotometric detection box can directly feedback the detection results to the controller, and the controller can judge whether it is cleaned or whether the detergent needs to be replaced according to the results, and realize the intelligent regulation of the entire circuit by controlling the opening and closing of the valve.

[0015] Further, there are two sets of the detergent bottle groups, including a first detergent bottle and a second detergent bottle. The first detergent bottle and the second detergent bottle are connected in parallel with each other and are respectively connected to the second connecting pipe through a three-way valve.

[0016] Further, the detergents in the first detergent bottle and the second detergent bottle are kerosene and / or trichloroethylene.

[0017] Since the media used inside the functional tubes for different purposes are different, different detergents are also used. For the asphalt viscosity tube, two detergents are required, that is, it is washed once with the detergent kerosene in the first detergent bottle, then washed once with trichloroethylene in the second detergent bottle, and finally dried with hot air. For oils, it can be directly washed with one detergent and then dried with hot air. For ordinary glass, it can be dried with hot air.

[0028] The first cleaning agent bottle 6 and the second cleaning agent bottle 7 are respectively connected to the second connecting pipe 5 in parallel through a first three-way valve 14 and a second three-way valve 15. The end of the second connecting pipe 5 is connected to a heater 8 and is communicated with the outside air through a short pipe 16. The first cleaning agent bottle 6 is close to the functional pipe 4 and contains kerosene inside. The second cleaning agent bottle 7 is close to the heater 8 and the cleaning agent inside is trichloroethylene.

[0029] The first connecting pipe 3 penetrates through the box body 9. The light source 10 and the detector 11 are oppositely arranged, and the connection line between the two passes through the first connecting pipe 3.

[0030] The functional pipe 4 in this embodiment is a viscosity pipe with a U-shaped structure, and the medium is asphalt.

[0031] A storage rack 17 is provided above the ultrasonic cleaning box 12. The storage rack 17 is used to fix the functional pipe 4. The cleaning box assembly further includes a temperature probe 18. The top of the temperature probe 18 is fixed on the storage rack 17, and the other end extends into the ultrasonic cleaning box 12. A high-temperature resistant camera 19 is also installed on the side wall of the cleaning box assembly. By connecting to a controller, it can transmit monitoring data in real time to judge the cleaning effect.

[0032] The controller of the present utility model can control the start and stop of electrical components such as the pressure pump 1, the detector 11, the camera 19, the heater 8, and the valves of the cleaning agent bottles, as well as the adjustment of parameters. The specific design of the controller is not the core invention point of the present utility model and can be a device in the prior art.

[0033] Connectors 20 are also provided at both ends of the functional pipe 4; a capillary tube 22 is inserted at the liquid outlet end of the functional pipe 4; drain ports 23 are provided at the bottom sides of the waste liquid collection buffer bottle 2 and the ultrasonic cleaning box 12. According to different pipes, the connector 20 can be in the shape of a plug or a pipe sleeve sleeved on the pipe opening, both of which are within the protection scope of this solution.

[0034] Place the tested functional tube 4 on the storage rack 17, connect the plug 20, press the start key of the controller to start cleaning, the instrument starts to run, and the heating source 13 starts the water bath to heat up; when the specified temperature is reached, the first three-way valve 14 opens, the pressure pump 1 starts, and the liquid in the first cleaning agent bottle 6 is sucked into the functional tube 4 under the action of pressure until the absorbance detected by the detector 11 changes significantly, then the pressure pump 1 stops, that is, the absorbance of air changes to the absorbance of kerosene and asphalt mixture, and at this time, ultrasonic waves start. After 3 minutes, stop the ultrasonic waves, close the first three-way valve 14, open the second three-way valve 15, start the pressure pump 1, quantitatively suck 20 mL of trichloroethylene into the functional tube 4, close the pressure pump 1, and at this time, measure the absorbance.

Within the framework of this solution, by changing the pipeline diameter, changing the volume of the sucked solvent, changing the solvent type, quantity, etc., all are within the protection scope of the present utility model.

[0036] Embodiment 2

[0037] The difference between this embodiment and Embodiment 1 is that in this embodiment, the substance to be cleaned is a non-asphalt petroleum product. The present utility model only designs a set of cleaning agent bottles, that is, the first cleaning agent bottle 6, with the internal solvent being trichloroethylene, which is connected to the second connecting tube 5 through the first three-way valve 14.

[0038] Embodiment 3

[0039] The difference between this embodiment and Embodiment 2 is that in this embodiment, the first cleaning agent bottle 6 has petroleum ether as the internal solvent.

[0040] It should be noted that for the cleaning methods in Embodiments 1 to 3, it can be judged whether ethanol rinsing is needed according to different substances to be cleaned. If ethanol rinsing is needed, just connect a parallel rinsing cleaning agent bottle. That is, if the substance to be cleaned is not asphalt but other petroleum products, then the cleaning agent bottle is filled with not kerosene but only cleaning agents (such as trichloroethylene, petroleum ether, etc.), and then it can be selected whether to rinse with ethanol; if the substance to be cleaned is a cleaner substance, then the cleaning agent can only be ethanol. The above cleaning principle is based on the principle of similar solubility, that is, the cleaning agent substance is not fixed. Therefore, on the basis of the present utility model, cleaning achieved by changing the solvent, changing the cleaning sequence, etc. is within the protection scope of the present utility model.

[0041] The above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it.

Those skilled in the art can also make other changes within the spirit of the present utility model for use in the design of the present utility model, as long as they do not deviate from the technical effects of the present utility model. These changes made in accordance with the spirit of the present utility model should all be included within the scope of protection required by the present utility model.
