Description

Technical Field

[0001] This utility model relates to the field of liquid dyeing machine technology, specifically to a dye liquor circulation device for a liquid dyeing machine. Background Technology

[0002] Liquid flow dyeing machines are a type of dyeing equipment widely used in the textile industry. They are suitable for bleaching, refining, dyeing, and washing processes of various natural, synthetic, and blended fibers. Liquid flow dyeing machines are commonly used for dyeing polyester fabrics during production. Currently, overflow dyeing machines typically guide excess dyeing liquid directly to a filter screen for recycling when reusing excess dyeing liquid for polyester fabrics. The excess dyeing liquid is then filtered to remove impurities before recycling. However, as excess dyeing liquid is continuously filtered, a layer of impurities accumulates on the filter screen, causing it to become clogged and making it difficult to continuously filter and recycle excess dyeing liquid. Therefore, in view of this, the present invention proposes a dye liquor circulation device for a liquid flow dyeing machine to make up for and improve the deficiencies of the prior art. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a dye liquor circulation device for a liquid dyeing machine, including a recovery cylinder, a support frame fixedly connected to the bottom end of the recovery cylinder, a filter screen fixedly connected to the inner wall of the recovery cylinder, and further including: The scraping assembly includes a rotating shaft rotatably connected to the center of the filter screen, an arc-shaped scraper fixedly connected to the outer surface of the rotating shaft, a support platform fixedly connected to the outer surface of the recycling cylinder, and a collection box slidably connected to the support platform. When the rotating shaft carries the arc-shaped scraper to rotate, the arc-shaped scraper scrapes the accumulated impurities into the collection box.

[0004] Preferably, the collection box has an inlet, and the recycling cylinder has a discharge port, with the discharge port connected to the inlet.

[0005] Preferably, the scraping assembly also includes a motor fixedly mounted on a support frame, and the output end of the motor is fixed to the rotating shaft.

[0006] Preferably, the intermittent infusion assembly includes a rotating block fixedly connected to the outer surface of the rotating shaft, and a baffle is fixedly connected to the end of the rotating block away from the rotating shaft.

[0007] Preferably, the intermittent infusion assembly also includes a drain hole at the bottom of the recovery cylinder, and the diameter of the drain hole is smaller than the diameter of the baffle.

[0008] Preferably, the intermittent infusion assembly also includes a collection hopper fixedly connected to the bottom of the recovery cylinder, and the bottom of the collection hopper is connected to an infusion tube.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This utility model, through the scraping component, can utilize the continuous rotation of the rotating shaft to make the arc-shaped scraper rotate on the top surface of the filter screen. The centrifugal force generated by the rotation of the arc-shaped scraper, as well as the guiding scraping action of the arc-shaped scraper, causes the impurities accumulated on the top surface of the filter screen to enter the collection box through the feed inlet and feed outlet for storage. This not only prevents the filter screen from clogging, but also makes it convenient for personnel to centrally process the impurities. This invention, through its intermittent infusion component, utilizes a rotating block that follows the rotation of the rotating shaft, causing the baffle to rotate in a circular motion. This repeatedly seals and releases the drain hole, intermittently discharging equal amounts of the recovered dye liquor from the recovery cylinder into the collection hopper. These equal amounts are then introduced through the infusion pipe to the circulating spray dye liquor location, facilitating the intermittent and equal supply of recovered dye liquor and improving its utilization rate.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Embodiments of this utility model Please refer to Figures 1 to 4As shown, a dye liquor circulation device for a liquid dyeing machine includes a recovery cylinder 1, a support frame 2 fixedly connected to the bottom end of the recovery cylinder 1, a filter screen 5 fixedly connected to the inner wall of the recovery cylinder 1, and further includes: The scraping assembly 3 includes a rotating shaft 32 rotatably connected to the center of the filter screen 5. An arc-shaped scraper 33 is fixedly connected to the outer surface of the rotating shaft 32. Two sets of arc-shaped scrapers 33 are provided, and the two sets of arc-shaped scrapers 33 form an S-shaped scraper. A support platform 37 is fixedly connected to the outer surface of the recycling cylinder 1. A collection box 35 is slidably connected to the support platform 37. The bottom end of the arc-shaped scraper 33 is in contact with the top surface of the filter screen 5. When the arc-shaped scraper 33 rotates, it uses the centrifugal force generated by its rotation to scrape the impurities accumulated on the top surface of the filter screen 5 toward the collection box 35. When the rotating shaft 32 carries the arc-shaped scraper 33 to rotate, the arc-shaped scraper 33 scrapes the impurities accumulated on the filter screen 5 into the collection box 35. The collection box 35 has an inlet 36 located in the middle section of the collection box 35. The recycling cylinder 1 has a passage 34 located directly above the filter screen 5 and connected to the inlet 36. This allows impurities accumulated on the filter screen 5 to pass through the passage 34 and the inlet 36 and be stored in the collection box 35 when the arc scraper 33 rotates. The scraping assembly 3 also includes a motor 31 fixedly mounted on the support frame 2, and the output end of the motor 31 is fixed to the rotating shaft 32. The bottom end of the rotating shaft 32 rotates through the recycling cylinder 1, and the motor 31 is located below the recycling cylinder 1. The above solution is adopted: by using the scraping assembly 3, the continuous rotation of the rotating shaft 32 can cause the arc-shaped scraper 33 to rotate on the top surface of the filter screen 5. The centrifugal force generated by the rotation of the arc-shaped scraper 33, as well as the guiding scraping of the arc-shaped scraper 33, can cause the impurities accumulated on the top surface of the filter screen 5 to enter the collection box 35 through the feed port 34 and the feed inlet 36 for storage. This not only prevents the filter screen 5 from clogging, but also makes it convenient for personnel to centrally process the impurities.

[0014] Please refer to Figures 2 to 4 As shown, the intermittent infusion assembly 4 includes a rotating block 42 fixedly connected to the outer surface of the rotating shaft 32, and a baffle 43 fixedly connected to one end of the rotating block 42 away from the rotating shaft 32; the intermittent infusion assembly 4 also includes a drain hole 41 opened at the bottom of the recovery cylinder 1, and the diameter of the drain hole 41 is smaller than the diameter of the baffle 43. The drain hole 41 is located on the circumferential rotation path of the baffle 43, so that when the baffle 43 rotates with the rotating block 42, the drain hole 41 intermittently discharges the filtered dye solution in the recovery cylinder 1; The intermittent infusion assembly 4 also includes a collection hopper 44 fixedly connected to the bottom of the recovery cylinder 1. A clearance frame is fixed between the collection hopper 44 and the recovery cylinder 1. The clearance frame can provide space for the rotation of the baffle 43 and prevent the baffle 43 from being blocked by the collection hopper 44 when rotating. The bottom of the collection hopper 44 is connected to an infusion pipe 45. The collection hopper 44 is located directly below the drain hole 41, and the infusion pipe 45 facilitates the discharge of the dye solution from the drain hole 41. The above scheme is adopted: by setting the intermittent infusion component 4, the rotating block 42 can follow the rotation of the rotating shaft 32, so that the baffle 43 can follow the rotation of the rotating shaft 32, thereby repeatedly sealing and unsealing the drain hole 41, and intermittently discharging the dye liquor recovered in the recovery cylinder 1 into the collection hopper 44. In this way, the equal amount is introduced into the circulating spray dye liquor position through the infusion pipe 45, which is conducive to intermittent and equal supply of recovered dye liquor and improves the utilization rate of recovered dye liquor.

[0015] Working principle and usage process of this utility model: First, the staff guides the excess dyeing liquid from the polyester fabric to the top of the recovery cylinder 1, isolating impurities in the excess dyeing liquid to the top surface of the filter screen 5. The dyeing liquid then passes through the filter screen 5 and is stored between the recovery cylinder 1 and the filter screen 5. Next, the end of the infusion pipe 45 away from the collection hopper 44 is connected to the circulating spray dyeing liquid supply position. At this time, the remote control motor 31 is started, causing the rotating shaft 32 to rotate along with the arc-shaped scraper 33 and the rotating block 42. The centrifugal force generated by the rotation of the arc-shaped scraper 33, as well as the guiding scraping of the arc-shaped scraper 33, causes the impurities accumulated on the top surface of the filter screen 5 to enter the collection box 35 for storage through the feed port 34 and the feed inlet 36. The rotation of the rotating shaft 32 causes the baffle 43 to rotate in a circle, thus repeatedly sealing and releasing the drain hole 41. The dyeing liquid recovered in the recovery cylinder 1 is intermittently discharged into the collection hopper 44 in equal amounts, and then introduced into the circulating spray dyeing liquid supply position in equal amounts through the infusion pipe 45.
