Description

Technical Field

[0001] This invention relates to the field of pipeline cleaning technology, and in particular to a filter rod conveying pipeline cleaning device and method. Background Technology

[0002] In the field of cigarette processing and packaging machinery, filter rod conveying pipes in cigarette filter rod manufacturing equipment connect the filter rod transmitter and receiver. Powered by high-pressure air, the filter rods are transported from the transmitter to the receiver for use by the cigarette rolling machine. The inner diameter of the conveying pipe is slightly larger than the outer diameter of the filter rod. When the filter rod passes through the pipe at high speed for a long time, plasticizers and adhesives may seep out due to insufficient curing time, adhesive seepage from the filter paper, or localized overheating in the pipe. This residue mixes with filter paper powder, dust, and other impurities, forming scale buildup in the pipe. Excessive scale buildup increases the resistance to filter rod emission, preventing even emission and potentially causing the filter rod to tear and burst, ultimately leading to blockage of the filter rod conveying pipe.

[0003] Currently, cleaning the scale buildup in the launch pipes mainly relies on manual cleaning methods, which are time-consuming, inefficient, and have poor results in removing scale buildup from the pipes. Summary of the Invention

[0004] The first objective of this invention is to provide a filter rod conveying pipeline cleaning device. This device starts the main pump to allow organic solvent to flow through the filter rod conveying pipeline, dissolving the scale buildup in the pipeline without damaging it. Then, high-pressure gas is introduced into the filter rod conveying pipeline through a gas pipeline for pulse cleaning, which generates a powerful pulse cleaning effect on the organic solvent and allows the organic solvent to be discharged after the filter rod conveying pipeline is cleaned.

[0005] The second objective of this invention is to provide a method for cleaning filter rod conveying pipelines, which aims to solve the problem of how to thoroughly clean pipelines without damaging the inner wall of the pipeline.

[0006] This invention provides a filter rod conveying pipeline cleaning device, including a housing;

[0007] The chamber contains an organic solvent, and one end of the main pump is connected to the chamber via a pipe at the bottom of the chamber.

[0008] The other end of the main pump is connected to the filter rod conveying pipeline through the lower pipe of the housing;

[0009] The lower pipe of the housing is also connected to a gas pipe, one end of which is connected to the filter rod conveying pipe, and the gas pipe is also connected to a solenoid valve.

[0010] Preferably, a heating element is installed at the bottom of the housing.

[0011] Preferably, the enclosure includes an inner enclosure and an outer enclosure, with insulation material filling the space between the outer enclosure and the inner enclosure.

[0012] Preferably, the housing is also connected to an auxiliary pump, which is connected to a lower pipe of the housing.

[0013] Preferably, the gas pipeline is also equipped with a pressure gauge, which is connected to a pressure adjustment knob.

[0014] Preferably, a temperature sensor is connected to the housing, and the temperature sensor is connected to a temperature controller.

[0015] Preferably, a pressure gauge is connected to the lower pipe of the housing.

[0016] The present invention also provides a method for cleaning a filter rod conveying pipeline, comprising the filter rod conveying pipeline cleaning device described in any of the above claims and using the following steps to clean the filter rod conveying pipeline:

[0017] S1: The heating element is powered on and heats up, while the temperature controller keeps the organic solvent in the chamber at the set temperature.

[0018] S2: Press the main pump button to start the main pump. The organic solvent flows back to the chamber through the lower pipe of the chamber, the main pump, the filter rod delivery pipe, and the upper pipe of the chamber.

[0019] S3: Press the pulse button to allow high-pressure gas in the gas pipeline to enter the filter rod delivery pipeline for pulse cleaning;

[0020] S4: Press the replenishment button to start the auxiliary pump. The organic solvent is replenished through the first tee port of the lower pipe of the tank, the auxiliary pump, and the second tee port of the lower pipe of the tank.

[0021] S5: Press the replenishment + pulse button to perform the replenishment function and pulse cleaning function simultaneously;

[0022] S6: Turn off the main pump switch and start the pulse button. High-pressure pulse gas enters the filter rod delivery pipe through the lower pipe of the box and discharges the residual organic solvent in the pipe to the box through the upper pipe of the box.

[0023] In a further preferred embodiment, in step S6, the used organic solvent in the tank is discharged through the tank's drain pipe.

[0024] In a further preferred embodiment, in step S3, the gas pressure is controlled by a gas pressure regulating knob.

[0025] Beneficial effects:

[0026] The technical solution of this invention involves activating the main pump to allow organic solvent to flow through the filter rod delivery pipeline, dissolving the scale buildup within the pipeline without damaging it. Then, high-pressure gas is introduced through a gas pipeline for pulse cleaning, providing a powerful pulsed clean of the organic solvent and venting the solvent out after cleaning.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] like Figures 1 to 6 As shown, the present invention provides a filter rod conveying pipeline cleaning device, which includes a housing 7, an organic solvent placed inside the housing 7, one end of a main pump 8 connected to the housing through a lower pipe 9 of the housing, the other end of the main pump 8 connected to the filter rod conveying pipeline through the lower pipe 9 of the housing, the lower pipe 9 of the housing is also connected to a gas pipe 1, one end of the gas pipe 1 is connected to the filter rod conveying pipeline, and the gas pipe 1 is also connected to a solenoid valve 2.

[0040] The technical solution of this invention involves activating the main pump 8 to allow organic solvent to flow through the filter rod delivery pipeline, dissolving the scale buildup within the pipeline without damaging the pipeline itself. Then, high-pressure gas is introduced into the filter rod delivery pipeline through the gas pipeline 1 for pulse cleaning, providing a powerful pulsed cleaning of the organic solvent and venting the organic solvent after cleaning. The entire device effectively solves the problem of filter rod delivery pipeline blockage, reduces filter rod consumption due to blockage, and improves the quality of the delivered filter rods.

[0041] Specifically, in this embodiment, the housing 7 is made of 304 stainless steel with a thickness of 1.5mm, and is filled with heat insulation cotton to keep the organic solvent warm after heating and to prevent operators from being burned.

[0042] The main pump 8 has a power of 1100W, a head of 45m, a suction lift of 10m, and is a high-temperature resistant stainless steel core intelligent self-priming pump. It is used to provide pressure and head for the solvent, so that the solvent circulates in the filter rod delivery pipeline.

[0043] A heating tube 5 is installed at the bottom of the chamber 7. The heating tube 5 is used to heat the organic solvent inside the chamber 7. In this embodiment, the heating tube 5 is a 220V 3KW type and is connected in a star configuration.

[0044] The box 7 includes an inner box and an outer box. The space between the outer box and the inner box is filled with heat insulation cotton to keep the heated organic solvent warm and to prevent the operator from being burned.

[0045] A temperature sensor 6 is connected to the housing 7, and the temperature sensor 6 is connected to a temperature controller 30. The temperature sensor 6 is a PT100 temperature sensor, and the temperature controller 30 is model XMTD-82GK1. The temperature sensor 6 measures the temperature of the organic solvent and converts the temperature signal into an electrical signal, which is then transmitted to the temperature controller 30. The temperature controller 30 controls the on / off state of a solid-state relay connected to the heating tube 5 to maintain a certain temperature for the organic solvent.

[0046] The housing 7 is also connected to an auxiliary pump 10, which is connected to the lower pipe 9 of the housing. Specifically, the auxiliary pump 10 is a 24V / L1078-180W high-temperature diaphragm pump. The auxiliary pump connects to the filter rod delivery pipe inlet 13 via the lower pipe 9, the first tee port 4, and the second tee port 14, and is used to replenish the filter rod delivery pipe with organic solvent. The filter rod delivery pipe outlet 12 is located next to the filter rod delivery pipe inlet 13.

[0047] like Figure 3 As shown, the lower pipe 9 of the housing is divided into two parts. One part of the lower pipe 9 connects directly to the bottom of the housing and is connected to the inlet of the main pump 8. The other part of the lower pipe 9 connects to the outlet of the main pump 8. The organic solvent flows through the lower pipe 9 after passing through the outlet of the main pump 8, and then flows to the inlet 13 of the filter rod delivery pipe. The organic solvent then flows back to the housing 7 through the upper pipe 11. The upper pipe 11 and the lower pipe 9 have a wall thickness of 2.3 mm and a diameter of 20 mm, are made of stainless steel, and are connected by threads. They are used to transport the organic solvent. It should be noted that the main pump 8 is connected in series, while the auxiliary pump is connected in parallel.

[0048] like Figure 3 As shown, the T-junction in the middle of the lower pipe 9 of the tank is connected to the input port of the auxiliary pump 10, and the output port of the auxiliary pump 10 is connected to the T-junction of the lower pipe 9 of the tank to realize the liquid replenishment circuit.

[0049] like Figure 4 As shown, a pressure gauge 17 is also installed on the gas pipeline 1, and the pressure gauge 17 is connected to a pressure adjustment knob 18. According to the gas pressure displayed by the pressure gauge 17, the pressure is controlled by the pressure adjustment knob 18 to keep the gas pressure displayed by the pressure gauge 17 within a certain range, so as to prevent the cleaning device from being damaged due to excessive pressure.

[0050] The lower pipe 9 of the housing is connected to an internal pressure gauge 19 to detect the pressure of organic solvent in the filter rod conveying pipe, preventing excessive pressure from damaging the cleaning device.

[0051] The pulse controller 28 is model DH48S-S(H5CN), and the solenoid valve 2 is model 2W-025-08. Pressing the pulse button 22 activates the pulse controller 28, controlling the solenoid valve 2 to actuate, thereby controlling the compressed gas in gas pipeline 1 to enter the filter rod delivery pipeline, achieving powerful cleaning of the filter rod delivery pipeline. After cleaning, pressing the pulse button 22 releases high-pressure pulsed gas into the filter rod delivery pipeline, venting any residual organic solvent in the pipeline to the housing 7.

[0052] The liquid replenishment button 21 controls the auxiliary pump 10 to replenish the filter rod delivery pipeline.

[0053] The replenishment + pulse button 23 simultaneously enables pulse cleaning and replenishment functions.

[0054] Select the appropriate main switch 33, heating element switch 27, main pump switch 29, auxiliary pump switch 32, and DC power switch 31, according to... Figure 5 and Figure 6 Connect electrical wiring.

[0055] Manual control of the corresponding devices is achieved through the heating element switch 27, the main switch 33, the main pump switch 29, the auxiliary pump switch 32, and the DC power switch 31, which are used to protect the pipeline cleaning device.

[0056] like Figures 4 to 6 As shown, the replenishment button 21, the main pump switch 29, the auxiliary pump switch 32, and the replenishment + pulse button 23 are respectively equipped with indicator lights 20 corresponding to the replenishment button, 25 corresponding to the main pump button, 26 corresponding to the auxiliary pump button, and 24 corresponding to the replenishment + pulse button.

[0057] The DC power supply converts AC power into DC power to power the auxiliary pump 10 and the control circuit.

[0058] All materials used in devices that come into direct contact with organic solvents are corrosion-resistant.

[0059] The present invention also provides a method for cleaning a filter rod conveying pipeline, comprising the above-mentioned filter rod conveying pipeline cleaning device and using the following steps to clean the filter rod conveying pipeline:

[0060] S1: Close the main switch 33, heating element switch 27, main pump switch 29, auxiliary pump switch 32, and DC power switch 31. Temperature sensor 6 detects that the organic solvent has not reached the set temperature, the solid-state relay is energized, the heating element 5 is energized to heat, and the temperature controller 30 maintains the organic solvent at the set temperature.

[0061] S2: Press the main pump switch 29, the contactor 35 is energized, the corresponding contacts are engaged, the main pump 8 starts, and the organic solvent flows back to the box 7 through the lower pipe 9 of the box, the main pump 8, the filter rod delivery pipe and the upper pipe 11 of the box.

[0062] S3: Stubborn scale buildup appears in the filter rod delivery pipeline. Press the pulse button 22 to power on the pulse controller 28, which controls the opening and closing of the solenoid valve 2. High-pressure gas in the gas pipeline 1 enters the filter rod delivery pipeline for pulse cleaning. The gas pressure is controlled by the gas pressure regulating knob 18.

[0063] S4: After the gas enters the filter rod delivery pipeline, there will be insufficient organic solvent. The liquid pressure detection gauge in the pipe shows a pressure drop. At this time, press the liquid replenishment button 21, the auxiliary pump 10 starts, and the organic solvent is replenished through the first tee port 4 of the lower pipe 9 of the box, the auxiliary pump 10, and the second tee port 14 of the lower pipe 9 of the box.

[0064] S5: Press the replenishment + pulse button 23. The replenishment function and the pulse cleaning function are performed simultaneously, ensuring that the pressure inside the pipe is relatively stable while completing the powerful cleaning function.

[0065] S6: Turn off the main pump switch 29, start the pulse button 22, and the high-pressure pulse gas enters the filter rod delivery pipe through the lower pipe 9 of the housing, and discharges the residual organic solvent in the pipe to the housing 7 through the upper pipe 11 of the housing. Finally, the used waste organic solvent in the housing 7 is discharged through the housing drain pipe 16.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
