[0002] Setting machines are crucial equipment in the textile industry, primarily used for heat-setting fabrics to ensure dimensional stability and appearance quality. With the continuous development and technological advancements in the textile industry, the functions and performance of setting machines are constantly improving, particularly in increasing production efficiency, reducing energy consumption, and enhancing product quality. Efficient setting processes not only enhance product market competitiveness but also reduce resource consumption, aligning with the principles of sustainable development.

[0003] Chinese Patent CN204898319U discloses a steam setting machine, comprising a setting machine body, a setting machine inlet frame, a width limiter, a sizing machine, a speed compensation device, a central control panel, a steam circulation box, a width adjustment machine, an exhaust system, and an outlet device. The setting machine inlet frame is fixed to the rear of the setting machine body. The exhaust system is located at the bottom of the setting machine. The central control panel is located on one side of the setting machine body. The sizing machine is located at the top of the body. The central control panel is connected to a microcontroller to control the sizing machine, the width limiter, the speed compensator, and the steam circulation box, all electrically connected. The outlet device is located at the front of the setting machine body. The setting machine body is rectangular.

[0004] Regarding the aforementioned technologies, when the sizing machine is working, a large amount of lint and other impurities will remain in the sizing solution. In order to avoid affecting the quality of the fabric, the sizing solution in the sizing tank needs to be replaced continuously, resulting in a large waste of sizing solution. Utility Model Content

[0005] To reduce slurry waste, this application provides a slurry recovery device for a stenter.

[0006] The slurry recovery device for a setting machine provided in this application adopts the following technical solution:

[0007] A slurry recovery device for a setting machine includes a filter barrel. A slurry inlet pipe is connected to the top of the filter barrel, and a slurry outlet pipe is connected to the bottom of the filter barrel. A filter plate is connected inside the filter barrel, and the periphery of the filter plate is connected to the inner wall of the filter barrel. A scraper is connected to the filter barrel, with its length direction aligned with the radial direction of the filter barrel. A rotating component is connected to the filter barrel, which drives the scraper to rotate. The bottom of the scraper contacts the top of the filter plate, and the rotation axis of the scraper is collinear with the central axis of the filter barrel.

[0008] By adopting the above technical solution, during use, the slurry is raised into the filter tank through the slurry inlet pipe. The filter plate filters the slurry, thereby reducing impurities in the slurry, facilitating slurry recovery and reducing slurry waste. The slurry is stored in the filter tank. When the slurry passes through the filter plate, the rotating component drives the scraper to rotate, causing the scraper to push away the impurities accumulated on the top of the filter plate, minimizing the blockage of the filter plate by impurities, and thus increasing the rate at which the slurry rises to the filter plate.

[0009] Optionally, the filter canister has a movable opening at the top, and a mounting plate is connected to the top of the filter canister. The mounting plate covers the movable opening. The filter canister is connected to a bracket, and the bracket is connected to a movable component. The movable component is used to drive the mounting plate to move vertically.

[0010] By adopting the above technical solution, impurities tend to accumulate on the top of the filter plate after long-term use. When cleaning the impurities on the top of the filter plate, the moving component drives the mounting plate to move vertically, thereby moving the mounting plate away from the filter barrel and opening the moving port, which makes it easier for operators to clean the impurities on the top of the filter plate.

[0011] Optionally, the bracket has a movable groove, the length direction of which is consistent with the vertical direction. The movable component includes a lead screw, a first motor, and a slider. The length direction of the lead screw is consistent with the vertical direction, and the lead screw is rotatably connected in the movable groove. The first motor is connected to the bracket, and the output shaft of the first motor is connected to one end of the lead screw. The slider is threaded onto the lead screw and is slidably connected in the movable groove along the vertical direction. The slider is connected to the mounting plate.

[0012] By adopting the above technical solution, the first motor drives the lead screw to rotate, so that the slider slides vertically and is connected to the moving groove. The slider drives the mounting plate to move vertically, thereby moving the mounting plate closer to or away from the filter barrel, thereby opening or closing the moving port.

[0013] Optionally, the scraper is connected to a connecting cylinder, the length direction of which is consistent with the vertical direction, the central axis of which is collinear with the central axis of the filter barrel, the top end of which passes through and is rotatably connected to the mounting plate along its length direction, the rotating component includes a first gear, a second gear, and a second motor, the first gear is sleeved on the top end of the connecting cylinder, the first gear is located above the mounting plate, the central axis of the first gear is collinear with the central axis of the connecting cylinder, the second motor is connected to the top of the mounting plate, the second gear is connected to the output shaft of the second motor, and the first gear meshes with the second gear.

[0014] By adopting the above technical solution, when in use, the second motor drives the second gear to rotate, the first gear follows the second gear to rotate, the first gear drives the connecting cylinder to rotate, the scraper follows the connecting cylinder to rotate, and the scraper rotates and pushes the impurities on the top of the filter plate, thereby reducing the situation of impurities clogging the filter plate.

[0015] Optionally, the filter plate is slidably connected to the filter barrel in a vertical direction. A support ring is connected inside the filter barrel. The outer circumferential wall of the support ring is connected to the inner wall of the filter barrel. The central axis of the support ring is collinear with the central axis of the filter barrel. The top of the support ring is in contact with the bottom of the filter plate.

[0016] By adopting the above technical solution, impurities are easily adhered to the surface of the filter plate after long-term use, making it inconvenient to clean the filter plate inside the filter barrel. After the moving port is opened, the filter plate is moved vertically, thereby moving the filter plate away from the support ring and away from the filter barrel, thus facilitating the cleaning and replacement of the filter plate.

[0017] Optionally, a movable rod is slidably connected inside the connecting cylinder. The central axis of the movable rod is collinear with the central axis of the connecting cylinder. An mounting block is connected to the top of the filter plate. A limiting block is connected to the top of the mounting block. The length direction of the limiting block is consistent with the radial direction of the filter plate. The central axis of the mounting block is collinear with the central axis of the filter plate. A rotating groove is opened at the bottom of the movable rod for the mounting block and the limiting block to be embedded. A limiting groove is opened at the top of the rotating groove. The mounting block is rotatably connected to the rotating groove. The limiting block is rotatably connected to the limiting groove. When the filter plate is disassembled, the bottom of the limiting block contacts the inner wall of the bottom of the limiting groove. The movable rod is slidably connected to the connecting cylinder in the vertical direction. A locking component is connected to the movable rod to lock the movable rod in the connecting cylinder.

[0018] By adopting the above technical solution, when disassembling the filter plate, the moving rod slides vertically to the connecting cylinder, driving the mounting block and the limiting block to embed into the rotating groove. When the limiting block is embedded in the limiting groove, the moving rod is rotated, causing the limiting block to rotate and connect into the limiting groove, and the limiting block to contact the inner wall of the limiting groove. The moving rod is then locked in the connecting cylinder by the locking component, thus ensuring a stable connection between the limiting block and the moving rod. When the moving component moves the mounting plate away from the filter barrel, the filter plate moves with the mounting plate, moving away from the filter barrel, which facilitates the cleaning and replacement of the filter plate.

[0019] Optionally, a mounting groove is provided on the periphery of the moving rod, the length direction of the mounting groove being consistent with the radial direction of the moving rod. The locking assembly includes a first spring and a locking block. The length direction of the first spring is consistent with the length direction of the mounting groove. One end of the first spring along its length direction is connected to the inner wall of the mounting groove, and the other end of the first spring is connected to the locking block. The locking block is slidably connected to the mounting groove along its length direction. A first locking hole is provided on the periphery of the top end of the connecting cylinder. The first locking hole is located above the mounting plate. The length direction of the mounting groove of the locking block passes through the first locking hole. When the locking block passes through the first locking hole, the bottom of the limiting block contacts the inner wall of the bottom of the limiting groove.

[0020] By adopting the above technical solution, during use, the locking block is pressed into the mounting groove by the inner wall of the connecting cylinder, and the locking block presses the first spring, causing the first spring to deform. When the filter plate is disassembled, the moving rod is moved downward in the vertical direction. After the limiting block is embedded in the limiting groove, the moving rod is rotated so that the limiting block contacts the inner wall of the limiting groove and drives the locking block to approach the first locking hole. When the mounting groove is connected to the first locking hole, the first spring returns to its shape and pushes the locking block to slide and connect to the mounting groove along the length direction of the mounting groove. The first spring drives the locking block to pass through the first locking hole, thereby making the moving rod stably connected to the connecting cylinder and the limiting block stably connected to the moving rod. This facilitates the movement of the filter plate with the mounting plate and makes it easy to clean and replace the filter plate.

[0021] Optionally, a mounting ring is connected to the top of the filter plate, the central axis of the mounting ring is collinear with the central axis of the filter plate, and the outer circumferential wall of the mounting ring is in contact with the inner wall of the filter barrel.

[0022] By adopting the above technical solution and adding an installation ring, we can minimize the possibility of impurities falling from the top of the filter plate into the surrounding environment when the filter plate is disassembled, thereby reducing the pollution of the surrounding environment by impurities.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During use, the slurry is fed into the filter tank through the slurry inlet pipe. The filter plate filters the slurry to reduce impurities, facilitate slurry recovery, and reduce slurry waste. The slurry is stored in the filter tank. When the slurry is fed to the filter plate, the rotating part drives the scraper to rotate, which pushes the impurities accumulated on the top of the filter plate to avoid clogging the filter plate as much as possible, thereby increasing the rate at which the slurry is fed to the filter plate.

[0025] 2. With prolonged use, impurities tend to accumulate on the top of the filter plate. When cleaning the impurities on the top of the filter plate, the moving component moves the mounting plate vertically, thereby moving the mounting plate away from the filter barrel and opening the moving port, making it easier for operators to clean the impurities on the top of the filter plate.

[0026] 3. In use, the second motor drives the second gear to rotate, the first gear follows the second gear to rotate, the first gear drives the connecting cylinder to rotate, the scraper follows the connecting cylinder to rotate, the scraper rotates and pushes the impurities on the top of the filter plate, thereby reducing the situation of impurities clogging the filter plate.

A movable component 500 is connected to the bracket 400, and the mounting plate 300 is connected to the bracket 400 via the movable component 500.

[0038] When cleaning impurities from the top of the filter plate 200, the first motor 520 drives the lead screw 510 to rotate, causing the slider 530 to slide vertically into the moving groove 410, thereby driving the mounting plate 300 to move vertically, thus facilitating the opening and closing of the moving port 130.

A limiting block 222 is connected to the top of the mounting block 221, and its length is aligned with the radial direction of the moving rod 700. A rotating groove 720 is formed at the bottom of the moving rod 700 for the mounting block 221 and the limiting block 222 to be inserted. The length of the rotating groove 720 is aligned with the radial direction of the moving rod 700, and the mounting block 221 is rotatably connected within the rotating groove 720.

When the locking block 820 passes through the first locking hole 311, the bottom of the limiting block 222 contacts the inner wall of the bottom of the limiting groove 730. When the locking block 820 passes through the second locking hole 312, the moving rod 700 moves away from the limiting block 222. When the filter plate 200 is disassembled, the moving rod 700 moves downward along its length, so that the limiting block 222 is embedded in the limiting groove 730.

[0045] The implementation principle of the slurry recovery device for a setting machine according to an embodiment of this application is as follows: During use, the slurry enters the filter tank 100 through the slurry inlet pipe 110 and passes through the filter plate 200, thereby reducing impurities in the slurry and facilitating slurry recovery. When the slurry passes through the filter plate 200, the second motor 630 drives the second gear 620 to rotate, the second gear 620 drives the first gear 610 to rotate, and the second gear 620 drives the connecting cylinder 310 to rotate, causing the scraper 320 to rotate along with the connecting cylinder 310. The rotation of the scraper 320 pushes away impurities on the top of the filter plate 200, thereby reducing the clogging of the filter plate 200 by impurities and accelerating the rate at which the slurry passes through the filter plate 200.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
