Description

Technical Field

[0001] This utility model relates to the field of water jet loom technology, and in particular to a water supply filtration mechanism for a water jet loom. Background Technology

[0002] In existing technology, water jet looms use a jet of water to propel the weft yarn, achieving warp and weft weaving. The nozzles of a water jet loom spray a rapid, fine stream of water, but in actual use, small impurities in the water often cause clogging. Current methods involve installing a filter screen on the water tank's outlet pipe to filter the water. However, this has a problem: after a certain period of use, some mesh areas of the filter screen become clogged, causing a decrease in water flow from the outlet pipe, affecting the normal operation of the nozzles, and requiring frequent cleaning of the filter screen. This disrupts the normal operation of the water jet loom and reduces production efficiency. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a water supply filtration mechanism for a water jet loom, which can filter the water supply to the water jet loom and intermittently clean the cylindrical filter screen to ensure the normal operation of the water jet loom.

[0004] This utility model discloses a water supply and filtration mechanism for a water jet loom, including a water tank, a filter box arranged on the side of the water tank, an inlet pipe arranged on the water tank, a cylindrical filter screen arranged inside the filter box, the upper and lower ends of the cylindrical filter screen being sealed to the filter box, forming an annular water outlet cavity between the filter box and the cylindrical filter screen, the filter holes of the cylindrical filter screen being located within the water outlet cavity, a first water pipe connected to the top of the cylindrical filter screen extending into the water tank, and a water pump arranged on the first water pipe inside the water tank, and an outlet pipe arranged on the side wall of the filter box within the water outlet cavity, the outlet pipe being connected to the water jet loom; a drain pipe arranged at the bottom of the filter box corresponding to the inside of the cylindrical filter screen, the drain pipe being equipped with a drain valve, a drive motor arranged at the center above the cylindrical filter screen, the output end of the drive motor being equipped with a rotating shaft, the rotating shaft extending into the inside of the cylindrical filter screen, and bristles arranged on the rotating shaft inside the cylindrical filter screen, the bristles contacting the inner wall of the cylindrical filter screen.

[0005] A sewage pump is installed on the sewage pipe.

[0006] A pressure balancing pipe is installed on the top of the water tank.

[0007] The upper end of the cylindrical filter screen extends upward to the outside of the filter box, and the top of the cylindrical filter screen is closed. No filter holes are provided on the cylindrical filter screen outside the filter box. The drive motor is located on the top of the cylindrical filter screen, and the first water pipe is located on the side wall of the cylindrical filter screen outside the filter box.

[0008] The water supply and filtration mechanism of the water jet loom obtained by this utility model delivers water to the inside of the cylindrical filter screen through a water pump. After filtration, the water is output from the outlet pipe. The drive motor at the top of the cylindrical filter screen can drive the rotating shaft and brush to rotate, so as to clean the impurities inside the filter screen and finally discharge them from the drain pipe. This achieves automatic cleaning and ensures the continuous and stable operation of the water jet loom. Attached Figure Description

[0013] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0014] Example 1:

[0015] like Figures 1-4 As shown, this utility model discloses a water supply and filtration mechanism for a water jet loom, including a water tank 1, a filter box 2 arranged on the side of the water tank 1, a water inlet pipe 4 arranged on the water tank 1, a cylindrical filter screen 3 arranged inside the filter box 2, the upper and lower ends of the cylindrical filter screen 3 being sealed to the filter box 2, forming an annular water outlet cavity 14 between the filter box 2 and the cylindrical filter screen 3, the filter holes of the cylindrical filter screen 3 being located within the water outlet cavity 14, a first water pipe 5 connected to the top of the cylindrical filter screen 3, the first water pipe 5 extending into the water tank 1, and the first water pipe inside the water tank 1... A water pump 10 is installed on the filter box 2 within the water outlet chamber 14. A water outlet pipe 7 is installed on the side wall of the filter box 2, and the water outlet pipe 7 is connected to the water jet loom. A drain pipe 8 is installed at the bottom of the filter box 2 corresponding to the inside of the cylindrical filter screen 3. A drain valve 9 is installed on the drain pipe 8. A drive motor 6 is installed at the center above the cylindrical filter screen 3. A rotating shaft 12 is installed at the output end of the drive motor 6. The rotating shaft 12 extends into the inside of the cylindrical filter screen 3. Brush bristles 13 are installed on the rotating shaft 12 inside the cylindrical filter screen 3. The brush bristles 13 are in contact with the inner wall of the cylindrical filter screen 3.

[0016] The filter box 2 can be fixed by a bracket or directly to the side wall of the water tank 1. The water inlet pipe 4 replenishes the water tank 1, ensuring that the water tank 1 has sufficient water for the water jet loom. During normal water supply, the water pump 10 delivers water from the water tank 1 to the cylindrical filter screen 3, and under pressure, it enters the outlet chamber 14, finally being output to the water jet loom through the outlet pipe 7. During this process, the water is filtered through the cylindrical filter screen 3, and some impurities will accumulate on the inner wall of the cylindrical filter screen 3. To achieve cleaning without stopping the machine, the drive motor 6 can drive the rotating shaft 12 to rotate, and the bristles 13 on the rotating shaft 12 brush the impurities accumulated on the inner wall of the cylindrical filter screen 3, causing them to detach from the cylindrical filter screen 3. At this time, the drain valve 9 is opened, and the impurities can be discharged from the drain pipe 8 under water pressure. The opening degree of the drain valve 9 can be adjusted and set according to actual needs so that the drain flow does not affect the output flow of the water outlet pipe 7, thereby achieving automatic cleaning of the cylindrical filter screen 3 while maintaining the normal and stable operation of the water jet loom, greatly improving the processing efficiency of the water jet loom.

[0017] A sewage pump is installed on the sewage pipe 8. The design of the sewage pump allows impurities inside the cylindrical filter screen 3 to be brushed off and quickly discharged, achieving active discharge and making the discharge of impurities more efficient and stable.

[0018] An air pressure balancing pipe 11 is installed on the top of the water tank 1. The air pressure balancing pipe 11 on the top of the water tank 1 can balance the air pressure inside the water tank 1, so as to make the process of water inlet and outlet in the water tank 1 more stable and reliable, and keep the pressure inside the water tank 1 stable and safe.

[0019] The upper end of the cylindrical filter screen 3 extends upward to the outside of the filter box 2, and the top of the cylindrical filter screen 3 is closed. No filter holes are provided on the cylindrical filter screen 3 outside the filter box 2. The drive motor 6 is located on the top of the cylindrical filter screen 3, and the first water pipe 5 is located on the side wall of the cylindrical filter screen 3 outside the filter box 2.

[0020] The upper end of the cylindrical filter screen 3 extends to the outside of the filter box 2, and the outer cylindrical filter screen 3 is not provided with filter holes. This allows the first pipe to be installed on the side wall of the cylindrical filter screen 3 outside the filter box 2, ensuring that the first pipe does not interfere with the rotating shaft 12, brush bristles 13, etc. inside the cylindrical filter screen 3, and that the water supply is stable. Meanwhile, during normal operation, the cylindrical filter screen 3 is filled with water. During the sewage discharge process, the water level inside the cylindrical filter screen 3 may drop slightly, but the water level will not drop to the filter holes, thus maintaining a stable water flow rate to the outlet pipe 7 and ensuring the stable operation of the water jet loom.
