Description

Technical Field

[0001] The utility model relates to the technical field of textile production, in particular to a water loom filtering device. Background Art

[0002] The water jet loom is a shuttleless loom that uses a jet of water to pull the weft yarn through the shed. The frictional traction of the weft yarn by water jet insertion is greater than that by air jet insertion, and the diffusion is small. It is suitable for the weft insertion of smooth-surfaced synthetic fibers, glass fibers and other filaments. At the same time, it can increase the conductivity of synthetic fibers and effectively overcome static electricity in weaving. In addition, the water jet weft consumes less energy and has the lowest noise.

[0003] At present, water jet looms have been widely used, and water jet looms continuously need water during use. It is necessary to ensure that there is sufficient water in the water tank of the water jet loom. The water in the water tank needs to be filtered before entering the nozzle, otherwise impurities in the water may cause the nozzle to be blocked or damaged. In the prior art, a filter net is used to filter water. For example, the existing patent CN202223344835.8 discloses a water tank for a water jet loom that is easy to clean, including a box body, a placement groove is opened on the top of the box body, a filter box is arranged in the box body, a first filter net is opened on all four sides of the filter box, handles are fixedly arranged on both sides of the filter box, and placement blocks are fixedly arranged on the front and rear surfaces of the filter box; two outer frames are fixedly arranged in the box body, and card frames are slidably arranged in the two outer frames, and second filter nets are opened in the two card frames, and handles are fixedly arranged on the tops of the two card frames. In the utility model, the water tank of the water jet loom usually enters the nozzle directly without any filtration, which can easily damage the nozzle. The water tank is provided with two layers of second filter screens for filtration in the tank body, and a filter box is provided at the lower end of the water outlet interface. The water finally used will pass through the first filter screens on the four sides of the filter box and be filtered again, which greatly reduces the impurities in the water.

[0004] In the above-mentioned public patent document, impurities will adhere to the filter nets during the process of filtering the water in the water tank by the first filter net and the second filter net. Paragraph 0036 of the specification indicates that when the water tank needs to be cleaned, the filter box can be taken out by two handles to clean the first filter net thereon, and the card frames in the two outer frames can also be taken out by the handles to clean them. When the card frames are taken out from the outer frames, the second filter net will come into contact with the outer frames, and impurities attached to the second filter net will fall into the water tank, so that the water tank needs to be cleaned after cleaning the filter nets, and during the use of the water tank, the first filter net and the second filter net may reduce the filtering efficiency of water due to excessive impurities, thereby affecting the normal use of the water jet loom. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a water loom filtering device, the purpose of which is to solve the problem that too many impurities are attached to the filter screen in the water tank during use, resulting in reduced filtering efficiency and affecting the normal use of the water jet loom.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is: a water loom filtering device, including a water tank and a filter screen, the water tank is respectively provided with a water inlet and a water outlet at both ends along the length direction, and the inner wall of the water tank is evenly provided with installation grooves along the length direction of the water tank, the filter screen is slidably installed in the installation groove, the filter screen includes a first filter screen and a second filter screen, the arrangement direction of the first filter screen and the second filter screen is consistent with the direction from the water inlet to the water outlet, and the mesh aperture of the first filter screen and the second filter screen in each installation groove decreases successively from the water inlet to the water outlet.

[0007] The principles of this solution are:

[0008] By opening an installation groove along the length direction on the inner wall of the water tank and installing a filter in the installation groove, the first filter and the second filter are installed in the same installation groove at the same time. When water is injected into the water tank from the water inlet, the water is filtered through the first filter and the second filter in each installation groove. During the use of the first filter and the second filter, water first passes through the first filter and then the second filter. Therefore, there will be more impurities on the first filter than on the second filter. After a period of use, the first filter can be taken out of the installation groove, the second filter can be pushed to the side closer to the water inlet, and then the new filter can be placed at the position of the original second filter to achieve the replacement of the filter without delaying the use of the water tank.

[0009] The beneficial effects of this program are:

[0010] 1. By opening an installation slot in the water tank and installing the first filter and the second filter in the same installation slot at the same time, the filter can be replaced by replacing the filter closer to the water inlet during use, without affecting the normal use of the water tank, and without affecting the filtering effect of water, thereby not affecting the normal use of the water jet loom;

[0011] 2. By reducing the mesh diameter of the filter in the water tank in the direction from the water inlet to the water outlet, the filtration rate and filtration effect of water can be improved.

[0012] Further, a groove is provided on the side wall of each installation slot near the second filter screen, an electromagnet is fixedly installed at the bottom of the groove, a spring is fixedly installed on the electromagnet, an iron sheet is fixedly installed on the other end of the spring and extends out of the groove to abut against the filter screen, and the electromagnet is electrically connected to the power supply. By providing a groove on the side wall of each installation slot, and the spring in the groove abuts against the second filter screen when the electromagnet is not energized, when the staff takes the first filter screen out of the installation slot, the second filter screen drops under the action of the spring and pushes the second filter screen toward the side close to the water inlet, and the original second filter screen becomes a new first filter screen at this time, and then when the staff installs the new filter screen into the installation slot, the electromagnet is connected to the power supply to energize the electromagnet, and the spring shrinks into the groove under the attraction of the electromagnet to the iron sheet, thereby preventing the spring from hindering the installation of the new filter screen, and after the installation of the new filter screen is completed, the connection between the electromagnet and the power supply is disconnected, and the spring is retracted and abuts against the new second filter screen, and the above action is repeated when the filter screen is replaced.

[0013] Furthermore, a limiting groove is provided at the bottom of the water tank corresponding to the installation groove. The limiting groove provided at the bottom of the water tank where the installation groove is located can limit the first filter screen and the second filter screen in the installation groove to prevent the first filter screen and the second filter screen from tilting with the flow of water.

[0014] Furthermore, a handle is fixedly mounted on the top of each of the first filter screen and the second filter screen, and the first filter screen and the second filter screen can be replaced by pulling the handle.

[0015] Furthermore, a first lifting rod is fixedly installed between the handles of each first filter screen to fix each first filter screen together, and a second lifting rod is fixedly installed on the handle of each second filter screen to fix each second filter screen together, and the first lifting rod and the second lifting rod are arranged in parallel. The first lifting rod can realize the replacement of the first filter screen in each installation slot. When replacing the first filter screen, the staff can lift the first lifting rod to lift out the first filter screen in all the installation slots, so that all the first filter screens can be replaced in one action, and at this time, the springs in each installation slot will push the second filter screen to move to the side close to the water inlet. If the springs in some of the installation slots are damaged, as long as one spring pushes, all the second filter screens will move under the drive of the second lifting rod, thereby realizing the replacement of the first filter screen and the installation of the new second filter screen.

[0016] Furthermore, a drainage port is provided at the bottom of the water tank at the location of the water outlet, and a control valve is fixedly installed at the drainage port. In order to prevent the impurities that may exist in the water tank from being discharged from the water outlet into the nozzle of the water jet loom, the location where the water outlet is opened is a certain distance from the bottom of the water tank. Therefore, after the water tank is used up, a certain amount of water is still left in the water tank, and there may be impurities in the water. The drainage port can discharge the remaining water in the water tank out of the water tank, thereby preventing the water tank from becoming dirty and smelly due to the accumulation of water in the water tank for a long time.

DETAILED DESCRIPTION

[0021] The following is further described in detail through specific implementation methods:

[0022] like Figure 1-3As shown, the structure of a water loom filtering device is as follows: it includes a water tank 101, and a water inlet 104 and a water outlet 105 are opened at both ends of the water tank 101, and the water inlet 104 and the water outlet 105 are respectively opened at both ends of the length direction of the water tank 101, and along the length direction of the water tank 101, the inner wall of the water tank 101 is evenly opened with a mounting groove 102, and the bottom of the water tank 101 corresponding to the mounting groove 102 is opened with a limiting groove 103, and the size of the limiting groove 103 is consistent with that of the mounting groove 102, and a filter screen is slidably installed in the mounting groove 102, and the filter screen is filtered. The filter comprises a first filter screen 201 and a second filter screen. The arrangement order of the first filter screen 201 and the second filter screen is consistent with the direction from the water inlet 104 to the water outlet 105, that is, the first filter screen 201 in each installation groove 102 is closer to the water inlet 104 than the second filter screen. A groove 107 is provided on the side wall of each installation groove 102 close to the second filter screen. An electromagnet 108 is fixedly installed at the bottom of the groove 107 by means of threaded connection or the like. A spring 109 is fixedly installed on the electromagnet 108. One end of the spring 109 is fixed by welding. The first filter 201 and the second filter 201 are fixedly mounted on the electromagnet 108 by means of fixing, welding or the like, and the other end of the spring 109 is fixedly mounted with an iron sheet 110 by means of fixing, welding or the like, and the iron sheet 110 extends out of a groove and abuts against the second filter screen. The electromagnet 108 is electrically connected to a power supply, and the power supply is used to turn on and off the electromagnet 108 to control whether the electromagnet 108 has magnetism. Whether the electromagnet 108 has magnetism controls the contraction and extension of the spring 109. A handle 202 is fixedly mounted on the top of each first filter screen 201 and the second filter screen by means of fixing, welding or integral molding or the like. A first lifting rod 203 is fixedly installed between the handles 202 of each first filter screen 201 by bolting or welding, and a second lifting rod 205 is fixedly installed between the handles 202 of each second filter screen by bolting or welding. After the first filter screen 201 and the second filter screen are installed in the installation groove 102, the first lifting rod 203 and the second lifting rod 205 are in a parallel state.

[0023] In order to ensure that impurities deposited at the bottom of the water tank 101 do not enter the water outlet 105 and flow into the nozzle of the water jet loom, the water outlet 105 is opened on the side wall of the water tank 101, and in order to discharge impurities in the water tank 101 and the accumulated water below the water outlet 105 out of the water tank 101, a debris discharge port 106 is opened at the bottom of the water tank 101, and a control valve is fixedly installed at the debris discharge port 106, and the control valve controls the opening and closing of the debris discharge port 106.

[0024] The mesh diameters of the first filter screen 201 and the second filter screen in each installation slot 102 in the water tank 101 are consistent. From the water inlet 104 to the water outlet 105 of the water tank 101, the mesh diameters of the first filter screen 201 and the second filter screen in each installation slot 102 gradually decrease, that is, the mesh diameters of the first filter screen 201 and the second filter screen in the installation slot 102 closest to the water inlet 104 are the largest compared with the mesh diameters of the first filter screen 201 and the second filter screen in other installation slots 102, and the mesh diameters of the first filter screen 201 and the second filter screen in the installation slot 102 closest to the water outlet 105 are the smallest compared with the mesh diameters of the first filter screen 201 and the second filter screen in other installation slots 102.

[0025] The specific implementation process is as follows:

[0026] When using the water jet loom, water is injected into the water tank 101 from the water inlet of the water tank 101, and the water passes through the first filter screen 201 and the second filter screen at the position of each installation slot 102. The first filter screen 201 and the second filter screen filter the water, and then the water is discharged from the water tank 101 from the water outlet 105 and enters the nozzle of the water jet loom. In the process of filtering the water by the first filter screen 201 and the second filter screen in each installation slot 102 of the water tank 101, impurities will be attached to the first filter screen 201 and the second filter screen. In the same installation slot 102, the second filter screen has fewer impurities than the first filter screen 201. After the water jet loom has worked for a period of time, the staff can remove the impurities by pulling each first filter screen 201. The first lifting rod 203 on the filter 201 takes out the first filter 201 in all the installation slots 102 from the installation slots 102. At this time, under the action of the spring 109, the second filter will move to the side close to the water inlet 104, and the second filter becomes a new first filter 201. The staff then prepares a new first filter 201 and connects the electromagnet 108 to the power supply. The electromagnet 108 is energized and has magnetism to retract the spring 109. The staff then puts the new first filter 201 into the installation slot 102 to replace the filter. The filter can be replaced without affecting the normal operation of the water jet loom to ensure the filtration efficiency of water, thereby ensuring the normal operation of the water jet loom.
