[0041] like Figure 1-2 , a filter for a cloth wool washing device, comprising: a filter cartridge 1, a filter screen 2, an inner screen pressure sensing device 3, an outer screen pressure sensing device 4 and a screen flushing component 5;

[0042] The filter cartridge 1 is provided with a cartridge cavity 11; the filter screen 2 is installed in the cartridge cavity 11, and the filter screen 2 surrounds and forms a filter area 12; the input end of the cartridge cavity 11 is located outside the filter area 12, and the output end of the cartridge cavity 11 is located inside the filter area 12;

[0043] The net-inside pressure sensing device 3 is installed in the cylinder cavity 11 and is located in the filtering area 12; the net-outside pressure sensing device 4 is installed in the cylinder cavity 11 and is located outside the filtering area 12;

[0044] The flushing assembly 5 comprises: a flushing inlet pipe 51 and a flushing outlet pipe 52;

[0045] The output end of the flushing inlet pipe 51 is connected to the barrel cavity 11, and is used to output liquid to the barrel cavity 11 to flush the filter screen 2; the input end of the flushing outlet pipe 52 is connected to the barrel cavity 11, and is used to discharge the liquid for flushing the filter screen 2; the flushing outlet pipe 52 and the flushing inlet pipe 51 are respectively provided with flushing valves 53, and the internal pressure sensing device 3, the external pressure sensing device 4 and the flushing valve 53 are communicatively connected.

[0046] The present invention provides a filter for a wool washing device for cloth, wherein an inner-net pressure sensing device 3 and an outer-net pressure sensing device 4 are respectively arranged at the inner and outer positions of the filter screen 2, and the filter cartridge 1 is provided with a flushing inlet pipe 51 and a flushing outlet pipe 52. The flushing assembly 5 can be mobilized according to the real-time pressure difference feedback between the inner-net pressure sensing device 3 and the outer-net pressure sensing device 4 to flush the filter screen 2, thereby solving the problem that the wool fibers in the filter block the filter screen 2, resulting in a low flushing pressure output by the filter cartridge 1 and unstable wool washing effect.

[0047] Specifically, the filter screen 2 is arranged in the cylinder cavity 11 of the filter cartridge 1; the filter screen 2 occupies a certain space in the cylinder cavity 11, thereby surrounding a specific space and forming a filter area 12; the filter cartridge 1 inputs liquid from the area outside the filter area 12, the liquid passes through the filter screen 2 and enters the filter area 12, and the wool fibers will remain in the filter screen 2, and the liquid in the filter area 12 is then discharged through the output end of the filter cartridge 1; under normal conditions, the flow rates at the input end and the output end of the filter cartridge 1 are the same or close; but after the filter screen 2 has been used for a long time, the filter screen 2 will accumulate impurities such as wool fibers, and the wool fibers will block part of the mesh openings of the filter screen 2, resulting in a large difference in the flow rates at the input end and the output end of the filter cartridge 1; in this regard, the present scheme sets an internal pressure sensing device 3 at the filter area 12, and sets an external pressure sensing device 4 outside the filter area 12. When the water pressure detected in real time by the internal pressure sensing device 3 and the external pressure sensing device 4 is greatly different, it indicates that When the liquid level difference between the filter area 12 and the liquid level outside the filter area 12 is large, the filtering work of the filter can be suspended; the system can be based on the real-time pressure difference between the pressure sensing device 3 inside the network and the pressure sensing device 4 outside the network; when the number of wool fibers is large, the pressure of the pressure sensing device 4 outside the network is greater than that of the pressure sensing device 3 inside the network, and the system can control the flushing valve 53 to open, and input liquid into the flushing inlet pipe 51, and the liquid can be tap water, etc. The liquid flushes the filter screen 2, and the wool fibers on the filter screen 2 fall under the impact of the liquid and finally separate from the filter screen 2, and the wool fibers are then output from the filter cartridge 1 through the flushing outlet pipe 52 with the liquid; when the water pressure difference detected in real time by the pressure sensing device 3 inside the network and the pressure sensing device 4 outside the network is within a specific range, the system controls the flushing valve 53 of the flushing inlet pipe 51 to be closed to stop flushing the filter screen 2, and after the liquid for flushing the filter screen 2 is discharged, the flushing valve 53 of the flushing outlet pipe 52 is closed, and the filtering work of the filter is restarted. In this way, the linkage of the pressure sensing device 3 inside the net, the pressure sensing device 4 outside the net and the flushing valve 53 can ensure that the input and output of the filter cartridge 1 always maintain a specific pressure difference, and the water output of the filter cartridge 1 is stable, which can ensure a stable wool washing effect.

[0048] In this solution, the communication connection method refers to the communication between connected devices through signal transmission interaction, which can be divided into wired connection and wireless connection; wired connection includes conventional data cable connection; wireless connection includes conventional WiFi, Bluetooth, infrared, NFC, etc.

[0049] Optimally, the number of the filter cartridges 1 is multiple; when the output ends of some of the filter cartridges 1 output liquid, some of the filter cartridges 1 flush the filter screen 2 through the flushing inlet pipe 51 .

[0050] The number of filter cartridges 1 in this solution is multiple, and each filter cartridge 1 is independently provided with a filter screen 2, a pressure sensing device 3 inside the screen, a pressure sensing device 4 outside the screen, and a screen flushing component 5; therefore, the filter can adjust the use status of multiple filter cartridges 1 as needed, for example, mobilizing one of the filter cartridges 1 to output the wool washing liquid to the wool washing tank 01, and mobilizing the screen flushing component 5 of one of the filter cartridges 1 to flush the filter screen 2, so that multiple filter cartridges 1 cyclically alternately output the wool washing liquid and flush the filter screen 2, and at least one filter cartridge 1 is in a stable output state, thereby ensuring a stable wool washing effect. For example, the first cartridge filter 03 is in a state of outputting liquid to the wool washing tank 01, and the second cartridge filter 04 is in a state of flushing the filter screen 2.

[0051] A cloth wool washing device, comprising: a wool washing tank 01, a water inlet pipe 02, a first cartridge filter 03, a second cartridge filter 04 and a spray pipe 05;

[0052] The first cartridge filter 03 and the second cartridge filter 04 are filters of the above-mentioned cloth wool washing device;

[0053] The output end of the wool washing tank 01 is connected to the input end of the water inlet pipe 02; one of the output ends of the water inlet pipe 02 is connected to the input end of the first cartridge filter 03, and a first control valve 031 is provided at the connecting position; one of the output ends of the water inlet pipe 02 is connected to the input end of the second cartridge filter 04, and a second control valve 041 is provided at the connecting position; the first cartridge filter 03 and the second cartridge filter 04 are respectively connected to one of the input ends of the spray pipe 05 within the filtering area 12 of the cartridge cavity 11, and the output end of the spray pipe 05 is connected to the wool washing tank 01.

[0054] Textile cloth is placed in the wool washing tank 01, and a large amount of liquid is needed to wash it to wash away the wool fibers on the textile cloth; the liquid in the wool washing tank 01 is also output to the first cartridge filter 03 and / or the second cartridge filter 04 through the water inlet pipe 02, and the input end of the filter cartridge 1 receives the liquid in the wool washing tank 01 outside the filtering area 12, and the liquid is accompanied by wool fibers; and the filter net 2 isolates the wool fibers, and the wool fibers will accumulate at the filter net 2, and will remain in the filter net 2 after using the filtering function for a long time; therefore, this solution can mobilize the flushing component 5, and the system can be based on the pressure sensing device 3 inside the net and the pressure sensing device outside the net. 4, controls the flushing valve 53 to open, inputs liquid into the flushing inlet pipe 51, and the liquid flushes the filter screen 2. The wool fibers on the filter screen 2 fall under the action of water flow and gravity and are finally separated from the filter screen 2; the wool fibers are then output from the filter cartridge 1 through the flushing outlet pipe 52 along with the liquid; when the water pressure difference detected in real time by the pressure sensing device 3 inside the screen and the pressure sensing device 4 outside the screen is within a specific range, the system controls the flushing valve 53 of the flushing inlet pipe 51 to close to stop flushing the filter screen 2, and after the liquid for flushing the filter screen 2 is discharged, closes the flushing valve 53 of the flushing outlet pipe 52, and thus restarts the filtering work of the filter. After the first cartridge filter 03 or the second cartridge filter 04 is flushed, it is in a state of stably outputting liquid. After the water inlet pipe 02 outputs liquid to the cylinder cavity 11 again, the liquid passes through the filter screen 2 and enters the filter area 12, and is output outside the filter cartridge 1 through the spray pipe 05; the output end of the spray pipe 05 faces the wool washing tank 01, and the spray pipe 05 flushes the textile fabric in the wool washing tank 01, thereby reusing the liquid in the wool washing tank 01 and being able to uniformly discharge the wool fibers outside the wool washing tank 01, thereby solving the problem that the existing wool washing device consumes a lot of water and requires manual cleaning of the filter screen 2, resulting in low wool washing efficiency and insufficient stability.

[0055] Generally, the wool washing tank 01 can use the hydraulic pressure difference to output the liquid to the filter cartridge 1 of the first cartridge filter 03 or the filter cartridge 1 of the second cartridge filter 04. For example, the wool washing tank 01 is set at a higher position than the filter cartridge 1 to output the liquid through the height difference.

[0056] In the most preferred embodiment, the cloth wool washing device further comprises: a booster pump 06;

[0057] The booster pump 06 is disposed on the water inlet pipe 02 and is used to pump the liquid in the wool washing tank 01 to the filter cartridge 1 .

[0058] The booster pump 06 can output the liquid in the wool washing tank 01 to the filter cartridge 1 through the water inlet pipe 02, specifically to the filter cartridge 1 of the first cartridge filter 03 or the filter cartridge 1 of the second cartridge filter 04, thereby accelerating the liquid delivery speed and further increasing the liquid circulation speed of the wool washing device.

[0059] It can be optimized to further include: a return pipe 07;

[0060] The input end of the return pipe 07 is connected to the spray pipe 05 , and the output end of the return pipe 07 is connected to the water inlet pipe 02 ; the return pipe 07 is provided with a return proportional valve 071 .

[0061] The spray pipe 05 is used to output liquid into the wool washing tank 01. In general embodiments, the liquid in the spray pipe 05 needs to first enter the wool washing tank 01 and then be output from the wool washing tank 01 to the water inlet pipe 02; and in the optimal embodiment, the return pipe 07 directly connects the spray pipe 05 and the water inlet pipe 02, that is, the liquid output from the spray pipe 05 can directly flow back from the return pipe 07 to the water inlet pipe 02; in particular, the return pipe 07 is provided with a reflux proportional valve 071, and the reflux proportional valve 071 can be adjusted to adjust the flow rate of the liquid through the reflux pipe 07, which can not only control the output flow rate of the spray pipe 05, but also shorten the path of the liquid returning to the water inlet pipe 02, so as to improve the utilization rate of the liquid.

[0062] Optimally, it also includes: a flow meter 08;

[0063] The flow meter 08 is disposed on the spray pipe 05 and is located between the input end of the reflux pipe 07 and the output end of the spray pipe 05 ; the flow meter 08 is communicatively connected to the reflux proportional valve 071 and / or the booster pump 06 .

[0064] The flow meter 08 is used to detect the flow at the output end of the spray pipe 05 in real time. An output flow rating can be set for the flow meter 08. When the flow detected by the flow meter 08 exceeds the output flow rating, the reflux proportional valve 071 can be controlled to increase the switch ratio of the reflux proportional valve 071, so that more liquid flows out of the reflux pipe 07, thereby reducing the flow output from the spray pipe 05, so that the real-time flow of the spray pipe 05 remains close to the output flow rating. When the flow detected by the flow meter 08 is lower than the output flow rating, the reflux proportional valve 071 can be controlled to reduce the switch ratio of the reflux proportional valve 071, thereby limiting the output of liquid from the reflux pipe 07, thereby increasing the flow output from the spray pipe 05, so that the real-time flow of the spray pipe 05 remains close to the output flow rating, so that the spray pipe 05 outputs a constant flow.

[0065] Similarly, the flow meter 08 can also control the booster pump 06. When the flow rate detected by the flow meter 08 is lower than the rated value of the output flow rate, the frequency of the booster pump 06 can be controlled to increase. Based on the environment of lower pressure difference provided by the pressure sensing device 3 inside the network and the pressure sensing device 4 outside the network, the booster pump 06 accelerates the circulation of liquid and allows the liquid to flow through the end of the spray pipe 05, thereby increasing the output pressure.

[0066] It can be optimized to further include: an output pressure sensing device 09;

[0067] The output pressure sensing device 09 is installed on the spray pipe 05 and is located between the input end of the return pipe 07 and the output end of the spray pipe 05 ; the output pressure sensing device 09 is communicatively connected to the booster pump 06 .

[0068] The output pressure sensing device 09 is used to detect the pressure of the output end of the spray pipe 05 in real time. An output pressure rated value can be set for the output pressure sensing device 09. When the pressure detected by the output pressure sensing device 09 exceeds the output pressure rated value, the output frequency of the booster pump 06 can be controlled, thereby controlling the pressure of the spray pipe 05, so that the pressure of the spray pipe 05 is maintained close to the output pressure rated value, thereby achieving a constant pressure output of the spray pipe 05.

[0069] It can be optimized to further include: a wool washing nozzle 010;

[0070] A plurality of wool washing nozzles 010 are arranged in the wool washing tank 01 , and an output end of the spray pipe 05 is connected to the wool washing nozzle 010 .

[0071] There can be multiple wool washing nozzles 010, which can be arranged in the wool washing tank 01 as needed, and can simultaneously flush multiple positions of the wool washing tank 01, thereby improving the wool washing efficiency; when the spray pipe 05 outputs liquid to multiple wool washing nozzles 010, it can ensure that the wool washing nozzles 010 output liquid with constant pressure and constant flow.

[0072] It can be optimized to further include: a waste recycling box 011;

[0073] The output end of the flushing outlet pipe 52 is connected to the waste recovery box 011.

[0074] The waste recovery box 011 can be used to receive the wool fibers output from the flushing outlet pipe 52, so that the wool fibers of the cloth wool washing device are finally concentrated and output to the waste recovery box 011, and the wool fibers in the waste recovery box 011 only need to be recycled.

[0075] A textile printing and dyeing system is provided with the above-mentioned cloth surface wool washing device.
