Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile processing, in particular to a water-jet loom. BACKGROUND

[0002] The water-jet loom is a shuttleless loom that uses a jet of water to draw the weft thread through the shed. It is suitable for weaving with long, smooth filaments. Because it uses water as the weft-drawing medium, a large amount of water is required during use. In order to save the water consumed by the water-jet loom, the water after being sprayed is recycled and purified for reuse. The purpose of purifying the recycled water is to avoid the phenomenon of clogging the spray head when the impurities and fibers in the recycled water are reused. For example, in the patent with the application number CN201310738664.3, a water-jet loom wastewater filtration structure is disclosed, which includes a filter box. The filter box includes two parallel first and second side walls. A semi-permeable membrane is arranged in the middle of the first and second side walls to divide the filter box into a filter cavity and a purification cavity. The surface of the semi-permeable membrane on the filter cavity side is uniformly distributed with iron powder. First and second electromagnets are arranged in the first and second side walls. The first and second electromagnets are electrically connected to a control circuit. The filter cavity includes a sewage inlet and an impurity outlet arranged at opposite ends. The invention uses the magnetic properties of the first electromagnet to alternately exceed and be lower than the magnetic properties of the second electromagnet, so that the iron powder loosens the textile fibers accumulated on the semi-permeable membrane and separates the textile fibers from the impurity outlet, keeping the surface of the semi-permeable membrane clean and improving the permeability of the semi-permeable membrane, saving energy and improving textile efficiency.

[0003] As for the water recycling and purification structure of the existing water-jet loom, the filter disc does not have a reverse cleaning structure. That is, the filter disc is a disposable consumable. When the filter disc is clogged to a certain extent, the water resistance increases and the flow rate decreases, resulting in a decrease in the spray pressure, which affects the normal use of the water-jet loom. Therefore, when the filter disc is clogged to a certain extent, it needs to be removed for manual cleaning and then reinstalled for use, or a new filter disc is directly replaced, which is more troublesome and has low practicality.

[0042] The side of the purification filter disc 301 close to the cleaning pump 202 is provided with a function top spring 3013, and the two ends of the function top spring 3013 are respectively abutted against the side of the purification filter disc 301 and the inside of the switching seat 204, the function top spring 3013 can realize energy storage, monitoring of filter disc blockage and other functions, and is also one of the main components for triggering the switching action of the control mechanism 3.

[0045] The purifying pump 201, the cleaning pump 202, the displacement sensor 2035 and the contact switch 2034 are electrically connected with an external power supply and a control device, and the specific structure and working principle thereof are mature technologies and will not be described here.

[0046] The specific use and role of the embodiment are as follows: in the present application, two groups of control mechanisms 3 can be used alternately. In the normal state, one group of control mechanisms 3 and the functional channels 2041 installed thereon are in communication with the cleaning channel 2032, so that the control mechanisms 3 in communication with the cleaning channel 2032 can realize the purifying and discharging of the water collected in the collecting cavity 101 into the clean water cavity 102 for jetting. When the power supply of the purifying pump 201 is turned on, the purifying pump 201 can pump the water in the collecting cavity 101 into the clean water cavity 102 through the purifying assembly. In this process, the water can flow through the filter disc in the purifying filter disc 301, so as to intercept the impurities and fibers in the pumped water on one side of the filter disc, so as to ensure the cleanliness of the water pumped into the clean water cavity 102, thereby realizing the purifying and pumping operation of the water in the collecting cavity 101. The other group of control mechanisms 3 and the functional channels 2041 installed thereon are in communication with the purifying channel 2031, so that the control mechanisms 3 in communication with the purifying channel 2031 can realize the reverse cleaning operation of the filter disc. When the power supply of the cleaning pump 202 is turned on, the cleaning pump 202 can pump the clean water in the clean water cavity 102 into the collecting cavity 101 through the purifying assembly. In this process, the water can also flow through the filter disc in the purifying filter disc 301. At this time, the clean water is reversely pumped from the clean water cavity 102 into the collecting cavity 101, so that the water can clear the impurities blocked and accumulated on one side of the filter disc when flowing through the filter disc, thereby realizing the reverse cleaning operation of the filter disc. When the filter disc of the control mechanism 3 in the water purifying operation is seriously blocked, the two groups of control mechanisms 3 can automatically switch the use position, so as to realize the continuous purifying of the water and the cleaning operation of the seriously blocked filter disc. With the increase of the use time and the continuous accumulation of impurities, the resistance of the water flowing through the filter disc of the control mechanism 3 in the water purifying operation will become larger. When the resistance becomes larger, the water cannot flow smoothly through the filter disc. At this time, under the action of water pressure, the purifying filter disc 301 of the filter disc is moved to one side and compresses the functional top spring 3013. When the guide column 302 moves to the position of the sinking groove 2331 with the purifying filter disc 301, two mechanisms are triggered. One is that the guide column 302 enters the guide groove 233 through the sinking groove 2331 under the action of the guide top spring 3021. The other is that the control lever 3011 abuts against the pressing switch 2034, so that the pressing switch 2034 temporarily cuts off the power supply of the purifying pump 201. Under the cooperation of the two mechanisms, the water flow pressure on the side of the purifying filter disc 301 disappears at this time, and because the groove depth of the guide groove 233 and the positioning groove 232 is greater than the groove depth of the positioning groove 232, the guide column 302 cannot return to the inside of the positioning groove 232 again. At this time, under the action of the functional top spring 3013, the guide column 302 can drive the switching seat 204 to rotate one hundred and eighty degrees through the guide groove 233.Thus, the two sets of control mechanisms 3 can be switched and used, and the guide column 302 of the other set of control mechanisms 3 can be inserted into the connection end of the positioning groove 232 and the rotating groove 231 after the switching action is completed, so as to automatically trigger the switching function when the internal filter disc of the purification filter disc 301 is blocked in the future.

[0047] In Example 2, on the basis of Example 1, the side surface of the purification filter disc 301 is provided with a track block 3012 with a “T” shaped cross section, and the inside of the switching seat 204 is provided with a track groove 2042, the track block 3012 is inserted into the inside of the track groove 2042, in use, the track block 3012 can limit the moving track of the purification filter disc 301, so that the purification filter disc 301 will not be skewed and twisted during movement, causing the device to be stuck and fail, and the use is stable.

[0048] In another embodiment, the purification channel 2031 is located at one end of the clean water cavity 102 and the cleaning channel 2032 is located at one end of the collection cavity 101, and a one-way valve is arranged in the inside of the collection cavity 101 and the clean water cavity 102, which can prevent the water in the collection cavity 101 and the clean water cavity 102 from interacting and thus prevent the water in the clean water cavity 102 from being contaminated, ensuring that the water in the clean water cavity 102 is always clean, and ensuring the normal and stable production of the water jet loom.
