Description

Technical Field

[0001] The invention relates to the technical field of tobacco, and in particular to a self-cleaning system for dehumidification pipelines of a loose dehumidification machine. Background Art

[0002] The tobacco industry's silk-making workshops are equipped with a number of high-temperature and high-humidity equipment, such as loosening and moisture recovery equipment and leaf moistening equipment, which are used to heat and humidify the materials in order to increase their flexibility and reduce breakage during the production process.

[0003] The outlet of drum equipment adopts a centralized dust removal and moisture removal system. During the moisture removal process, as the temperature drops below the dew point temperature, the water vapor in the moisture condenses and adheres to the wall of the moisture removal pipe. According to the distribution law of moisture in the circular pipe, the moisture removal pipe forms dust accumulation due to the combination of dust, broken smoke foam and other particulate matter in the moisture and condensed water on the pipe wall. As time goes on, the dust accumulation increases, forming a thick layer of smoke scale on the pipe wall.

[0004] This hidden warm and humid environment is a breeding ground for mold and odor.

[0005] In order to eliminate this quality risk, the workshop, on the one hand, has the operator flush the dehumidification pipeline with water after production. Since the pipeline is in the middle of the dehumidification hood and the inner diameter of the pipeline is small, the operator cannot visually check the cleaning situation and can only judge the flushing effect by sensory perception based on the color of the cleaning water, which takes about 33.9 minutes per flush. On the other hand, according to the production schedule every quarter, a professional cleaning company is invited to disassemble and maintain it, which takes a long time and has high maintenance costs. In summary, one is that the maintenance time is long, and the other is that the maintenance is not thorough. Third, the disassembly and maintenance takes a long time and is expensive. Summary of the invention

[0006] The present invention proposes a self-cleaning system for a dehumidification pipeline of a loose dehumidification machine. According to the cleaning requirements of the dehumidification pipeline, the present invention designs and manufactures an intelligent automatic cleaning device for the dehumidification pipeline, and the device is organically combined with a workshop production monitoring system.

[0007] Specifically, a self-cleaning system for a dehumidification pipeline of a loose dehumidification machine is proposed, comprising:

[0008] The cleaning module includes a dehumidification hood and a vertical pipeline. The dehumidification hood is connected to a vibration tank below. The vertical pipeline has an opening at 2 / 3, and a horizontal pipe is connected to the opening. One end of the horizontal pipe is connected to a surround nozzle, and the other end is connected to a three-way valve. The surround nozzle is arranged in the vertical pipeline, and the three-way valve is arranged outside the vertical pipeline. One end of the three-way valve is connected to a compressed air solenoid valve, and the other end is connected to a water solenoid valve. The water solenoid valve is connected to a water inlet pipeline. The waste water after cleaning flows into the vibration tank through the dehumidification hood and is discharged to the ground for treatment.

[0009] The detection module is connected to the cleaning module and includes a turbidity meter. The turbidity meter is arranged at the connection between the dehumidification pipeline and the dehumidification cover. The turbidity meter is used to detect the turbidity data of the cleaning water in real time. The turbidity meter includes a signal converter. The turbidity data is converted into a digital signal through the signal converter, and the data is smoothed and filtered to remove noise. The turbidity meter obtains the turbidity data of the cleaning water. The turbidity meter presets a first turbidity threshold and a second turbidity threshold, and the second turbidity threshold is greater than the first turbidity threshold. When the turbidity data obtained by the detection module is less than the first turbidity threshold, a signal is sent to the cleaning module to stop cleaning.

[0010] The air drying module is connected to the cleaning module and the detection module, and includes a compressed air solenoid valve. The compressed air solenoid valve is connected to the air compressor through a pipeline. After the cleaning module and the detection module stop, the air drying module is automatically started; after the compressed air solenoid valve is started, the electromagnetic coil generates electromagnetic force to lift the closing part from the valve seat, the valve opens, and compressed air enters the surround nozzle for 360° spraying to air dry the cleaning pipeline. The air drying program stops and the cleaning system ends.

[0011] As a preferred technical solution, the first turbidity threshold of the turbidity meter is set to 10.0 NTU.

[0012] As a preferred technical solution, the turbidity meter acquires turbidity data of the cleaning water at a frequency of one data point per second.

[0013] As a preferred technical solution, when the turbidity data of the cleaning water obtained by the turbidity meter is lower than the first turbidity threshold for 20 consecutive seconds, a first signal is sent to the cleaning module to stop cleaning; the cleaning module sends a second signal to the air drying module to air dry the pipeline.

[0014] As a preferred technical solution, the blowing time of the air-drying module is set to 110 to 120 seconds.

[0015] As a preferred technical solution, the pressure resistance of the surround nozzle is greater than or equal to 0.1 MPa.

[0016] As a preferred technical solution, a wide-angle curved surface is provided at the water outlet of the surround-type nozzle, and a plurality of spray holes are provided on the wide-angle curved surface.

[0017] As a preferred technical solution, the water inlet pipeline is connected to a pressure pump.

[0018] As a preferred technical solution, the cleaning module also includes a timing controller, and the water solenoid valve and the pressure pump are connected to the timing controller.

[0019] As a preferred technical solution, it also includes a real-time control monitoring interface to display the acquired turbidity data; when the acquired turbidity data value is greater than the second turbidity threshold, the system automatically alarms and gives fault diagnosis suggestions.

[0020] Compared with the prior art, the present invention has achieved the following technical effects: the present invention has remodeled the dehumidification pipeline, and designed and manufactured an intelligent pipeline cleaning device using a cleaning module, a detection module, and an air drying module, and automatically performed cleaning tests. The pipeline cleaning time was reduced from an average of 33.9 minutes to an average of 5.9 minutes, with an average time reduction of 28 minutes and a labor efficiency improvement of 474.58%.

[0021] The cleaning effect was tested and the turbidity of the cleaning water was reduced from 42.9NTU to 9.6NTU, which significantly improved the cleaning effect.

[0022] The intelligent cleaning device for dehumidification pipelines of the present invention operates smoothly, has a significant cleaning effect, and reduces the cleaning time. The use of the device greatly reduces the labor intensity of front-line workers, reduces maintenance time, reduces the amount of cleaning water from 0.3 tons / time to 0.06 tons / time, and reduces the waste of water resources. This intelligent cleaning device for dehumidification pipelines is the first of its kind in the industry and has a high industry promotion value.

[0023] Other features and advantages of the present application will be set forth in the following description, and in part will become apparent from the description, or may be understood by practicing the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Example

[0038] like Figure 1 As shown in the figure, a self-cleaning system for the dehumidification pipeline of a loose dehumidifier is proposed, which is organically combined with the workshop I FIX monitoring system. It includes:

[0039] The cleaning module 20 includes a dehumidification cover 40 and a vertical pipeline 50. The dehumidification cover 40 is connected to a vibration tank below. The length of the vertical pipeline 50 is generally 108 cm. The test is carried out according to the golden section method. Figure 2-3As shown, the vertical pipeline 50 has an opening at 2 / 3, and a circular hole with a diameter of 25 mm is opened at 66.7 cm measured from the top of the pipeline. A horizontal pipe 60 is connected to the circular hole opening. The length of the horizontal pipe 60 can be 8 cm and the diameter of the stainless steel water pipe is 25 mm. One end of the horizontal pipe 60 is connected to the surround nozzle 205, and the other end is connected to the three-way valve 70; the surround nozzle 205 is arranged in the vertical pipeline 50, and the three-way valve 70 is arranged outside the vertical pipeline 50. One end of the three-way valve 70 is connected to the compressed air solenoid valve 301, and the other end is connected to the water solenoid valve 201. The water solenoid valve 201 is connected to the water inlet pipeline 203. The cleaned wastewater flows into the seismic tank through the dehumidification cover 40 and is discharged to the ground for treatment.

[0040] Detection module 10, detection module 10 is connected to cleaning module 20, and detection module 10 will automatically start when the cleaning program starts. Detection module 10 includes turbidity meter 101, turbidity meter 101 is arranged at the connection between dehumidification pipe and dehumidification cover 40, and turbidity meter 101 is used to detect turbidity data of cleaning water in real time. Use turbidity meter 101 with 0≤range≤400NTU and measurement accuracy≤1% to monitor cleaning water in real time. Turbidity meter 101 includes signal converter 102, through which turbidity data is converted into digital signal, data smoothing and filtering are performed to remove noise. Turbidity meter 101 obtains turbidity data of cleaning water, and turbidity meter 101 presets first turbidity threshold and second turbidity threshold, and the second turbidity threshold is greater than the first turbidity threshold; when the turbidity data obtained by detection module 10 is less than the first turbidity threshold, a signal is sent to cleaning module 20 to stop cleaning.

[0041] Preferably, the first turbidity threshold of the turbidity meter 101 is set to 10.0 NTU. When the turbidity data of the cleaning water is detected to be lower than 10.0 NTU for 20 consecutive seconds, the program calculates and determines that the cleaning effect of the inner wall of the pipeline meets the requirements, and the program issues an instruction, and the cleaning module 20 and the detection module 10 stop working at the same time. Preferably, the turbidity meter 101 obtains the turbidity data of the cleaning water at a frequency of collecting one data per second.

[0042] The air-drying module 30 is connected to the cleaning module 20 and the detection module 10, and includes a compressed air solenoid valve 301. The compressed air solenoid valve 301 is connected to the air compressor through a pipeline. After the cleaning module 20 and the detection module 10 stop, the air-drying module 30 is automatically started. After the compressed air solenoid valve 301 is started, the electromagnetic coil generates an electromagnetic force to lift the closing part from the valve seat, the valve opens, and the compressed air enters the surround nozzle 205 for 360° spraying to air-dry the cleaning pipeline. Those skilled in the art should understand that the surround nozzle 205 here can be achieved by driving the nozzle with a rotating motor. The air-drying program stops and the cleaning system ends. Preferably, the spraying time can be set to 110 to 120 seconds. It can also be specifically set according to the actual length of the pipeline.

[0043] Furthermore, a humidity sensor can be installed inside the pipeline, and when the humidity reaches a preset value, the drying process is stopped. This configuration can more accurately control the humidity in the pipeline and prevent bacteria from growing in the pipeline.

[0044] Preferably, the water inlet pipeline 203 is connected to the pressure pump 202 .

[0045] Preferably, the pressure resistance of the surround nozzle 205 is greater than or equal to 0.1 MPa. Further, a wide-angle curved surface is provided at the water outlet of the surround nozzle 205, and a plurality of spray holes are provided on the wide-angle curved surface.

[0046] Preferably, the blowing time of the air drying module 30 is 110 to 120 seconds. The air drying module 30 automatically opens after the cleaning module 20 and the detection module 10 stop. The compressed air solenoid valve 301 is energized, and the electromagnetic coil generates electromagnetic force to lift the closing member from the valve seat, the valve opens, and the compressed air enters the nozzle, and the cleaning pipeline is air-dried through 360° non-dead angle blowing. The air drying program stops and the cleaning system ends.

[0047] Preferably, the cleaning module 20 also includes a timing controller 204, and the water solenoid valve 201 and the pressure pump 202 are connected to the timing controller 204. By setting the timing controller 204, fully automatic cleaning can be achieved. Furthermore, it also includes a real-time control monitoring interface to display the acquired turbidity data. Furthermore, when the acquired turbidity data value is greater than the second turbidity threshold, the system automatically alarms, displays the alarm information on the monitoring screen, and gives fault diagnosis suggestions. The second turbidity threshold is used to characterize abnormal turbidity in the pipe, reminding production personnel that deep cleaning is required, for example, if necessary, the pipeline needs to be disassembled for cleaning.

[0048] like Figure 5 As shown, the working process of the intelligent cleaning device for dehumidification pipeline is as follows:

[0049] (1) System initialization, including setting the cleaning water turbidity threshold, when the cleaning water turbidity value is ≤10.0NTU for 20 consecutive seconds, the cleaning program ends and the spraying time is 114S.

[0050] (2) Click the Start button.

[0051] (3) The electronic valve that controls water is turned on, and the cleaning water is delivered to the cleaning nozzle.

[0052] (4) Start cleaning with the 360° nozzle without dead angles.

[0053] (5) The turbidity meter 101 starts to detect the turbidity of the cleaning water and transmits data in a timely manner.

[0054] (6) When the turbidity of the cleaning water is lower than 10.0 NTU for 20 consecutive seconds, the cleaning process will be stopped after calculation and judgment. If the cleaning requirements are not met, cleaning will continue until the turbidity of the cleaning water meets the requirements.

[0055] (7) The cleaning module 20 and the detection module 10 stop working.

[0056] (8) The air-drying module 30 starts working.

[0057] (9) The solenoid valve controlling the air pressure starts working.

[0058] (10) Air is pressed into the nozzle and air drying begins.

[0059] (11) The timer starts counting and stops automatically when the spraying time reaches 114s.

[0060] (12) The pipeline cleaning process is completed.

[0061] contrast Figure 4 The traditional cleaning process can be replaced by the cleaning system of the present invention, which is simple and convenient to operate and effectively improves the cleaning efficiency.

[0062] Tables 1 and 2 below show the cleaning time statistics and cleaning water turbidity statistics of the cleaning system. Tables 3 and 4 show the cleaning time and cleaning water turbidity statistics of the traditional cleaning technology. It can be seen that the present invention has designed and manufactured an intelligent pipeline cleaning device by modifying the dehumidification pipeline using the cleaning module 20, the detection module 10 and the air-drying module 30, and automatically performs cleaning tests. The pipeline cleaning time is reduced from the previous average of 33.9 minutes to an average of 5.9 minutes, and the average time is reduced by 28 minutes, and the labor efficiency is improved by 474.58%. The cleaning effect was tested, and the turbidity of the cleaning water was reduced from the original 42.9NTU to 9.6NTU, and the cleaning effect was significantly improved.

[0063] The intelligent cleaning device for dehumidification pipelines of the present invention operates smoothly, has a significant cleaning effect, and reduces the cleaning time. The use of the device greatly reduces the labor intensity of front-line workers, reduces maintenance time, reduces the amount of cleaning water from 0.3 tons / time to 0.06 tons / time, and reduces the waste of water resources.
