Description

Technical Field

[0001] This application relates to the field of alkali reduction machines, and more particularly to a wastewater recovery device for an alkali reduction machine. Background Technology

[0002] The alkali reduction process for polyester woven fabrics is a crucial step in textile pretreatment. It involves etching the fiber surface with sodium hydroxide solution to improve fabric softness and dyeing uniformity. Currently, the alkali reduction process is typically performed using an alkali reduction machine.

[0003] Chinese patent CN208328411U discloses an alkali reduction machine that solves the problem of alkali waste caused by alkali being carried out during fabric output in existing alkali reduction machines. The machine includes a housing and an alkali tank inside the housing. An mounting rod is provided on the side wall of the housing, and multiple driven pressure rollers are rotatably mounted on the mounting rod, all positioned on the same plane. A sliding groove parallel to the mounting rod is provided on the side wall of the housing, and a driving pressure roller is slidably connected to the sliding groove. An alkali recovery device is provided inside the housing, comprising a recovery tank and a guide tank. An outlet is provided on the side wall of the recovery tank, and a filter screen is installed at the outlet. When the fabric comes out of the alkali tank, it will carry a large amount of alkali, which will cause the active and driven pressure rollers to press the fabric together. The drive mechanism drives the active pressure roller to reciprocate along the chute to squeeze the fabric, thereby squeezing out the alkali. The squeezed-out alkali is collected by the alkali recovery device, thus achieving the purpose of alkali recovery and preventing waste of alkali.

[0004] Regarding the aforementioned technologies, with prolonged use, impurities tend to accumulate on one side of the filter screen, potentially clogging it and affecting the filtration efficiency of the alkaline solution. Utility Model Content

[0005] In order to reduce the clogging of the first filter plate by impurities and improve filtration efficiency, this application provides a wastewater recovery device for an alkali reduction machine.

[0006] The wastewater recovery device for an alkali reduction machine provided in this application adopts the following technical solution:

[0007] A wastewater recovery device for an alkali reduction machine includes a filter box and a first filter plate. The filter box has an opening at the top, and the first filter plate is disposed inside the filter box. The filter box is located below a driven pressure roller. A scraper is provided inside the filter box, and a moving component is connected inside the filter box. The moving component is used to drive the scraper to move and scrape impurities off the surface of the first filter plate.

[0008] By adopting the above technical solution, during use, the active pressure roller and the driven pressure roller squeeze the fabric, and the excess alkali solution drips into the filter box and is initially filtered by the first filter plate. When impurities are stuck to the surface of the first filter plate, the moving component drives the scraper to move, so that the scraper pushes the impurities on the surface of the first filter plate, so as to avoid the accumulation of impurities and blockage of the first filter plate and improve the filtration efficiency.

[0009] Optionally, a cleaning port is provided at one end of the filter box along the moving direction of the scraper. The filter box is connected to a lifting component, which is used to move the first filter plate and drive the first filter plate closer to or away from the cleaning port. When the first filter plate is close to the cleaning port, the scraper contacts the first filter plate.

[0010] By adopting the above technical solution, when in use, the first filter plate is located below the cleaning port. When cleaning the first filter plate, the lifting component moves the first filter plate closer to the cleaning port, and the scraper pushes the impurities on the surface of the first filter plate out of the cleaning port, thereby facilitating the cleaning of impurities on the first filter plate, preventing filter screen blockage, improving filtration efficiency, and reducing the discharge of alkaline solution from the cleaning port during cleaning.

[0011] Optionally, the filter box is connected to a collection box, the collection box having an opening at the top and being located below the cleaning port.

[0012] By adopting the above technical solution, the scraper inside the filter box pushes impurities on the surface of the first filter plate toward the cleaning port, and the collection box can collect the impurities falling from the cleaning port, avoiding the impurities from falling randomly and polluting the environment, and facilitating centralized treatment of impurities.

[0013] Optionally, the lifting component includes a first cylinder and a sliding block. The first cylinder is connected to the filter box, the piston rod of the first cylinder is connected to the sliding block, and the first filter plate is detachably connected to the sliding block.

[0014] By adopting the above technical solution, the first cylinder drives the sliding block to move, thereby moving the first filter plate which is detachably connected to the sliding block. This enables the first filter plate to move closer to or further away from the cleaning port. When the first filter plate is close to the cleaning port, the scraper pushes away the impurities on the surface of the first filter plate, making it easier to clean the impurities. At the same time, the detachable connection method facilitates the individual maintenance and replacement of the first filter plate.

[0015] Optionally, the collection box is connected to a connecting block, and the filter box has a connecting groove. The connecting block is inserted into the filter box through the connecting groove, and the connecting block is detachably connected to the inner wall of the connecting groove by a locking component.

[0016] By adopting the above technical solution, the plug-in connection between the connecting block and the connecting groove, as well as the locking component, enables the detachable connection between the collection box and the filter box, which facilitates the subsequent disassembly and cleaning of the collection box and avoids excessive accumulation of impurities that could affect the normal operation of the device.

[0017] Optionally, the connecting block has an installation groove, and the locking assembly includes a first spring and a locking block. One end of the first spring is connected to the inner wall of the installation groove, and the other end of the first spring is connected to the locking block. A locking hole is provided on the inner wall of one end of the connecting groove. The first spring is used to push the locking block to move and drive the locking block through the locking hole.

[0018] By adopting the above technical solution, when disassembling the collection box, the locking block is pushed away from the locking hole, so that the connecting block is away from the connecting groove, thus facilitating the disassembly of the collection box. When installing the collection box, the connecting block is inserted into the connecting groove, and the mounting groove is close to the locking hole. The first spring pushes the locking block through the locking hole, so that the connecting block is stably connected to the filter box, and the collection box is stably connected to the filter box.

[0019] Optionally, a sliding groove is provided inside the filter box. The moving component includes a lead screw, a first motor, and a moving block. The lead screw is rotatably connected to the inner wall of the sliding groove. The first motor is used to drive the lead screw to rotate. The moving block is threaded onto the lead screw and slides against the inner wall of the sliding groove. The scraper is connected to the moving block.

[0020] By adopting the above technical solution, the first motor drives the lead screw to rotate, causing the moving block threaded onto the lead screw to slide in the sliding groove, thereby driving the scraper to move. This can push the impurities on the surface of the first filter plate into the collection box, preventing the impurities from accumulating and clogging the first filter plate, and improving the filtration efficiency.

[0021] Optionally, the collection box is connected to a drain pipe, and a second filter plate is connected inside the drain pipe.

[0022] By adopting the above technical solution, the collection box can collect impurities and some alkaline solution discharged from the cleaning port of the filter box, and the connected drain pipe can discharge the alkaline solution in the collection box, thereby reducing the accumulation of alkaline solution in the collection box and facilitating the recycling of alkaline solution.

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

[0024] 1. During use, the active pressure roller and the driven pressure roller squeeze the fabric, and excess alkali drips into the filter box. The alkali is then initially filtered by the first filter plate. When impurities adhere to the surface of the first filter plate, the moving component drives the scraper to move, so that the scraper pushes the impurities on the surface of the first filter plate, thus avoiding the accumulation of impurities and clogging the first filter plate, and improving the filtration efficiency.

[0025] 2. In use, the first filter plate is located below the cleaning port. When cleaning the first filter plate, the lifting component moves the first filter plate closer to the cleaning port, and the scraper pushes the impurities on the surface of the first filter plate out of the cleaning port. This facilitates the cleaning of impurities on the first filter plate, prevents the filter screen from clogging, improves filtration efficiency, and reduces the discharge of alkaline solution from the cleaning port during cleaning.

[0026] 3. The scraper inside the filter box pushes impurities on the surface of the first filter plate toward the cleaning port. The collection box can collect the impurities falling from the cleaning port, preventing impurities from scattering randomly and polluting the environment, and facilitating centralized treatment of impurities.
