Description

Technical Field

[0001] This invention relates to the field of impregnating agent recovery technology, specifically to an impregnating agent recovery device and recovery process with a quantitative tank proportioning method. Background Technology

[0002] Currently, the typical process for recyclable impregnating agents on the market is as follows: vacuum pressure impregnation – six-dimensional centrifugal spooling – high-pressure spray cleaning (step one) – high-pressure spray cleaning (step two) – hot water tumbling and curing. A recycling system is installed at the cleaning station. By adding a certain proportion of separating agent, the impregnating agent in the wash water is recycled in layers and reused. The existing recycling system adds the separating agent by installing a pulse water meter on the water supply pipeline. The pulse water meter sends a signal to the PLC based on the water supply volume. The PLC sends a signal to the separating agent metering pump based on the pulse signal from the water meter. The metering pump then pumps the separating agent from the storage tank into the cleaning water according to the set proportion based on the pulse signal.

[0003] However, the existing pulse signal-based liquid replenishment method is prone to the following problems: 1) The replenishment signal is issued by the pulse water meter, and there is an error between the water meter reading and the actual replenishment amount, resulting in pulse signal error; 2) The separator metering pump replenishes according to the pulse, and after the ratio is set, there is also an error in the pumping amount each time, requiring frequent ratio calibration; 3) Once the pulse signal is given, it cannot be stopped, and the separator storage tank may be emptied while the metering pump continues to run dry, resulting in the actual addition ratio of separator being lower than the set ratio, leading to abnormal recovery. Therefore, a quantitative cylinder-proportioned impregnating agent recovery device and recovery process are designed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to avoid the inaccuracy and instability problems in the traditional pulse signal form by adopting a mechanical mechanism.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a quantitative cylinder proportioning impregnating agent recovery device, comprising: a water replenishment tank, a separating agent storage tank, a separating agent replenishment tank, a water replenishment tank quantitative mechanism, a separating agent replenishment tank quantitative mechanism, and a PLC control center;

[0006] The water replenishment tank and the separator storage tank are arranged side by side on the frame that supports both, and the separator storage tank is located on the side of the frame.

[0007] The water replenishment tank metering mechanism is installed in the water replenishment tank to quantitatively determine the outflow of water from the water replenishment tank, and the separator replenishment tank metering mechanism is installed in the separator replenishment tank to quantitatively determine the outflow of separator from the separator replenishment tank.

[0008] The bottom of the water replenishment tank is connected to one end of a water replenishment pipe, the bottom of the separation agent replenishment tank 3 is connected to one end of a separation agent replenishment pipe, and the other end of the water replenishment pipe and the other end of the separation agent replenishment pipe are connected to an overflow tank installed in the immersion cleaning station.

[0009] The overflow tank is equipped with an overflow tank level float for monitoring the liquid level inside the overflow tank;

[0010] The water supply pipe is equipped with a pneumatic valve, and the separator supply pipe is equipped with a pneumatic valve.

[0011] The PLC control center interacts with the pneumatic valve of the water supply pipe, the pneumatic valve of the separator supply pipe, the metering mechanism of the water supply tank, the metering mechanism of the separator supply tank, and the level float of the overflow tank.

[0012] The parameters of the water replenishment tank and the separator replenishment tank are set according to the amount of water and separator replenishment required each time the immersion cleaning station is replenished. When the liquid level at the immersion cleaning station is insufficient, causing the overflow tank to be low and requiring replenishment, the overflow tank level float receives a low liquid level signal. The PLC control center transmits a signal to the pneumatic valves of the water replenishment pipe and the separator replenishment pipe, causing them to open. Water from the water replenishment tank enters the overflow tank through the water replenishment pipe for quantitative water replenishment, and separator from the separator replenishment tank enters the overflow tank through the separator replenishment pipe for quantitative separator replenishment. Once the overflow tank replenishment is complete, the PLC control center transmits a signal to the pneumatic valves of the water replenishment pipe and the separator replenishment pipe, causing them to close and stop replenishment.

[0013] As a preferred embodiment of the present invention, the water replenishment tank quantitative mechanism includes a water replenishment tank level float, which is used to monitor the water level change in the water replenishment tank. The water replenishment tank level float interacts with the PLC control center to set parameters for the water replenishment tank level float. When the water level in the water replenishment tank changes quantitatively, the water replenishment tank level float transmits a signal to the PLC control center.

[0014] As a preferred embodiment of the present invention, the quantitative mechanism of the separator replenishment tank includes a separator replenishment tank level float. The separator replenishment tank level float is used to monitor the level change of the separator in the separator replenishment tank. The separator replenishment tank level float interacts with the PLC control center to set parameters. When the level of the separator in the separator replenishment tank changes quantitatively, the separator replenishment tank level float transmits a signal to the PLC control center.

[0015] As a preferred embodiment of the present invention, the parameters of the water replenishment tank level float are set so that when the water replenishment tank level float detects a first change in the water level, it interacts with the PLC control center. The parameters of the separator replenishment tank level float are also set so that when the separator replenishment tank level float detects a second change in the water level, it interacts with the PLC control center. The ratio of the volume of the first change in water level to the volume of the second change in water level is 100:8.

[0016] As a preferred embodiment of the present invention, the water tank is provided with a water supply pipe, and the water supply pipe is provided with a water supply pneumatic valve.

[0017] As a preferred embodiment of the present invention, a main water supply valve is provided at the end of the water supply pipe.

[0018] As a preferred embodiment of the present invention, the separating agent storage tank is connected to the replenishing separating agent tank via a connecting pipe, and a connecting pipe pneumatic valve is provided on the connecting pipe.

[0019] As a preferred embodiment of the present invention, a main valve for the water supply pipe is provided at the connection between the water supply pipe and the overflow box.

[0020] As a preferred embodiment of the present invention, a main valve for replenishing the separator is provided at the connection between the separator replenishment pipe and the overflow tank.

[0021] A recovery process for recovering impregnating agent using the above-mentioned quantitative cylinder proportioning impregnating agent recovery device includes the following steps:

[0022] S1: Replenish the water tank with water and replenish the separator tank with separator, so that the water in the water tank reaches the required amount and the separator in the separator tank reaches the required amount.

[0023] S2: The overflow tank level float is set so that when the liquid level in the overflow tank is insufficient due to insufficient liquid level in the immersion cleaning station, the overflow tank level float will communicate with the PLC control center to transmit a replenishment signal.

[0024] S3: Set parameters for the water replenishment tank level float and the separation agent replenishment tank level float, such that when the ratio of the volume change in the water replenishment tank level to the volume change in the separation agent replenishment tank level is 100:8, the water replenishment tank level float and the separation agent replenishment tank level float simultaneously interact with the PLC control center, which is located in the external control console of the impregnation process;

[0025] S4: When the liquid level at the cleaning station of the impregnation process is insufficient, resulting in insufficient liquid level in the overflow tank, the PLC control center obtains a liquid replenishment signal, and the pneumatic valves of the water replenishment pipe and the separator replenishment pipe are opened. The water in the water replenishment tank enters the overflow tank through the water replenishment pipe, and the separator in the separator replenishment tank enters the overflow tank through the separator replenishment pipe.

[0026] S5: When the water level change monitored by the float ball in the water replenishment tank and the separation agent level change monitored by the float ball in the separation agent replenishment tank simultaneously reach their respective set parameters, the pneumatic valves of the water replenishment pipe and the separation agent replenishment pipe close.

[0027] S6: The overflow tank level float determines whether the overflow tank has been replenished. If the replenishment has not been completed, repeat steps S4-S5.

[0028] S7: Complete the replenishment of the overflow tank, replenish the water tank with water, and replenish the separator tank with separator, so that the water in the water tank reaches the required amount and the separator in the separator tank reaches the required amount.

[0029] The beneficial effects of this invention are reflected in:

[0030] 1. An overflow tank level float is used to determine whether the overflow tank needs replenishment. By setting level floats in the water replenishment tank and the separator replenishment tank, the mechanical nature of these floats ensures accurate detection of level changes in both tanks. Combined with pneumatic valves on the water and separator replenishment pipes, this allows for precise and quantitative replenishment of water and separator in both tanks. This ensures the overflow tank can be replenished quantitatively, avoiding the instability and inaccuracy caused by traditional pulse signal-based replenishment methods. Furthermore, the mechanical structure increases overall reliability, reduces the need for frequent maintenance, and prevents waste of impregnating agent caused by abnormal separator replenishment leading to recovery anomalies.

[0038] The invention will now be described in further detail with reference to the accompanying drawings.

[0039] Combined with appendix Figure 1-6 As shown, a quantitative cylinder-proportioned impregnating agent recovery device and recovery process includes a water replenishment tank 1, a separating agent storage tank 2, a separating agent replenishment tank 3, a connecting pipe 4, a connecting pipe pneumatic valve 5, a water replenishment pipe 6, a separating agent replenishment pipe 7, a water replenishment pipe pneumatic valve 8, a separating agent replenishment pipe pneumatic valve 9, a water replenishment tank level float 10, a separating agent replenishment tank level float 11, a water replenishment pipe 12, a water replenishment pneumatic valve 13, a water replenishment main valve 14, a water replenishment pipe main valve 15, a separating agent replenishment main valve 16, and an overflow tank 17.

[0040] Combined with appendix Figure 1-6As shown, a quantitative impregnating agent recovery device includes: a water replenishment tank 1, a separating agent storage tank 2, a separating agent replenishment tank 3, a water replenishment tank metering mechanism, a separating agent replenishment tank metering mechanism, and a PLC control center. The water replenishment tank 1 and the separating agent storage tank 2 are arranged side-by-side on a frame supporting both. The separating agent replenishment tank 3 is located on the side of the frame. The water replenishment tank metering mechanism, located in the water replenishment tank 1, is used to quantitatively determine the outflow of water from the water replenishment tank 1. The separating agent replenishment tank metering mechanism, located in the separating agent replenishment tank 3, is used to... The outflow of the separating agent in the separating agent tank 3 is quantitatively determined. A water supply pipe 6 is connected to the bottom of the water supply tank 1, and a separating agent pipe 7 is connected to the bottom of the separating agent tank 3. The other ends of the water supply pipe 6 and the separating agent pipe 7 are connected to an overflow tank 17 installed in the immersion cleaning station. An overflow tank level float is installed in the overflow tank 17 to monitor the liquid level. A pneumatic valve 8 is installed on the water supply pipe 6, and a pneumatic valve 9 is installed on the separating agent pipe 7. The P... The LC control center interacts with the pneumatic valve 8 of the water replenishment pipe, the pneumatic valve 9 of the separator replenishment pipe, the metering mechanism of the water replenishment tank, the metering mechanism of the separator replenishment tank, and the level float of the overflow tank. Preferably, the PLC control center is located in the external control console of the impregnation process. The water replenishment tank 1 is equipped with a water replenishment pipe 12, and a water replenishment pneumatic valve 13 is installed on the water replenishment pipe 12. A main water replenishment valve 14 is installed at the end of the water replenishment pipe 12. The separator storage tank 2 is connected to the separator replenishment tank 3 through a connecting pipe 4, and the connecting pipe 4 is equipped with... There is a connecting pipe pneumatic valve 5. Before use, the water supply pipe 12 is connected to the external water supply device, the main water supply valve 14 is in the normally open state, the water supply pneumatic valve 13 is opened, the water in the external water supply device is supplied to the water supply tank 1, the separating agent is added to the separating agent storage tank 2, so that the connecting pipe pneumatic valve 5 is in the open state, and the separating agent is supplied to the separating agent tank 3. After the supply is supplied, the water in the water supply tank 1 is at the required level, and the separating agent in the separating agent tank 3 is at the required level. Then the water supply pneumatic valve 13 is closed, and the connecting pipe pneumatic valve 5 is closed.

[0041] Combined with appendix Figure 1-6As shown, the water replenishment tank metering mechanism includes a water replenishment tank level float 10, which monitors the water level changes in the water replenishment tank 1. The water replenishment tank level float 10 interacts with the PLC control center to set parameters. When a metered change occurs in the water level in the water replenishment tank 1, the water replenishment tank level float 10 transmits a signal to the PLC control center. The separator replenishment tank metering mechanism includes a separator replenishment tank level float 11, which monitors the separator level changes in the separator replenishment tank 3. The separator replenishment tank level float 11 interacts with the PLC control center to set parameters. When the level of the separating agent in the replenishing separating agent tank 3 changes quantitatively, the level float 11 of the replenishing separating agent tank transmits a signal to the PLC control center. The parameters of the level float 10 of the replenishing water tank are set so that when the level of the replenishing water tank 1 changes first, it interacts with the PLC control center. Similarly, the parameters of the level float 11 of the replenishing separating agent tank 3 are set so that when the level of the replenishing separating agent tank 3 changes second, it interacts with the PLC control center. The ratio of the volume of the first level change to the volume of the second level change is 100:8. A main valve 15 for the replenishing water pipe is installed at the connection between the replenishing water pipe 6 and the overflow tank 17. The level float 7 of the replenishing separating agent tank... A main valve 16 for replenishing the separating agent is installed at the connection point with the overflow tank 17. Specifically, the volume is set to the unit volume of liquid level change in this application. The parameters of the water replenishment tank level float 10 are set so that when the liquid in the water replenishment tank 1 changes by 100%, the water replenishment tank level float 10 sends a signal. The parameters of the separating agent tank level float 11 are set so that when the liquid in the separating agent tank 3 changes by 8%, the separating agent tank level float 11 sends a signal. When the PLC control center simultaneously receives the signals from the water replenishment tank level float 10 and the separating agent tank level float 11, the pneumatic valve 8 of the water replenishment pipe and the pneumatic valve 9 of the separating agent replenishment pipe open, and the overflow tank level float is set so as to prevent insufficient liquid level at the cleaning station in the immersion process. When the liquid level in overflow tank 17 is insufficient, the overflow tank level float communicates with the PLC control center to transmit a replenishment signal. When the liquid level is insufficient, the indicator light on the overflow tank level float is off. When replenishment is needed, the overflow tank level float remains off, the PLC control center receives the replenishment signal, and the pneumatic valves 8 and 9 of the water replenishment pipe and the separator replenishment pipe open. Under gravity, water from water replenishment tank 1 and separator replenishment tank 3 are replenished into overflow tank 17. During replenishment, due to the parameter settings of the water replenishment tank level float 10 and the separator replenishment tank level float 11, the ratio of water to separator is 100:8, and the replenishment is quantitative. After one quantitative replenishment is completed, the pneumatic valves 8 and 9 of the water replenishment pipe and the separator replenishment pipe close.If the overflow tank 17 still needs replenishment at this time, continue to replenish the water and separating agent at a ratio of 100:8. Once the overflow tank 17 has been replenished, the pneumatic valve 8 on the water replenishment pipe and the pneumatic valve 9 on the separating agent replenishment pipe will remain closed. Then, water will be added to the water replenishment tank 1, and separating agent will be added to the separating agent replenishment tank 3.

[0042] A recovery process for recovering impregnating agent using the above-mentioned quantitative cylinder proportioning impregnating agent recovery device includes the following steps:

[0043] S1: Replenish water to the water replenishment tank 1 and replenish the separating agent to the separating agent replenishment tank 3, so that the water in the water replenishment tank 1 reaches the required amount and the separating agent in the separating agent replenishment tank 3 reaches the required amount.

[0044] S2: The overflow tank level float is set so that when the liquid level in the overflow tank 17 is insufficient due to insufficient liquid level in the immersion cleaning station, the overflow tank level float will communicate with the PLC control center to transmit a replenishment signal.

[0045] S3: Set parameters for the water replenishment tank level float 10 and the separation agent replenishment tank level float 11, such that when the ratio of the volume change in the water replenishment tank 1 to the volume change in the separation agent replenishment tank 3 is 100:8, the water replenishment tank level float 10 and the separation agent replenishment tank level float 11 simultaneously interact with the PLC control center, which is located in the external control console of the impregnation process;

[0046] S4: When the liquid level at the cleaning station of the impregnation process is insufficient, resulting in insufficient liquid level in the overflow tank 17, the PLC control center obtains a liquid replenishment signal, and the pneumatic valve 8 of the water replenishment pipe and the pneumatic valve 9 of the separator replenishment pipe are opened. The water in the water replenishment tank 1 enters the overflow tank 17 through the water replenishment pipe 6, and the separator in the separator replenishment tank 3 enters the overflow tank 17 through the separator replenishment pipe 7.

[0047] S5: When the water level float 10 of the water replenishment tank and the separation agent level float 11 of the separation agent replenishment tank simultaneously reach their respective set parameters, the pneumatic valve 8 of the water replenishment pipe and the pneumatic valve 9 of the separation agent replenishment pipe are closed.

[0048] S6: The overflow tank level float ball determines whether the overflow tank 17 has been replenished. If the replenishment has not been completed, repeat steps S4-S5.

[0049] S7: Complete the replenishment of the overflow tank 17, replenish the water tank 1 with water, and replenish the separator tank 3 with separator, so that the water in the water tank 1 reaches the required amount and the separator in the separator tank 3 reaches the required amount.
