Description

Technical Field

[0001] This application relates to the field of dyeing machine technology, and in particular to a device for removing impurities from the liquid surface of a dyeing machine. Background Technology

[0002] Fabric dyeing machines are indispensable pieces of equipment in the textile industry, widely used in the printing and dyeing of various fabrics. In actual production, impurities often appear on the surface of the dyeing tank, such as fiber scraps falling from the fabric. These impurities not only affect the uniform distribution of dye but may also cause a decline in product quality.

[0003] A common device for removing impurities from the liquid surface of a dyeing machine in related technologies includes a dyeing machine housing, a collection tank at the top inside the dyeing machine housing, a through hole inside the collection tank that penetrates the dyeing machine housing and extends to the outside of the dyeing machine housing and is connected to a filter, a filter screen inside the filter, and a storage tank connected to the side of the filter away from the collection tank, and the storage tank is connected to the inside of the dyeing machine housing through a water pump.

[0004] When the dyeing machine is working, fiber debris in the dye liquor floats to the surface and flows into a collection tank level with the surface of the dye liquor. Impurities, along with the dye liquor, enter the filter through the through-holes. After being filtered by the filter screen, the clean dye liquor enters the storage tank and is then pumped back into the interior of the dyeing machine.

[0005] In the process of developing this application, it was found that the technology has at least the following problems: when the filter screen filters fiber debris, the fiber debris will accumulate on the surface of the filter screen to form a fiber debris layer. The fiber debris layer will reduce the efficiency of the dye liquor passing through the filter screen. At this time, it is necessary to disassemble the filter and clean the filter screen, which is inconvenient. Therefore, it needs to be improved. Utility Model Content

[0006] To facilitate filter cleaning and ensure the filtration effect of the filter, this application provides a liquid surface impurity removal device for a fabric dyeing machine.

[0007] The liquid surface impurity removal device for a dyeing machine provided in this application adopts the following technical solution:

[0008] A device for removing liquid surface impurities in a dyeing machine includes a dyeing machine housing. A collection tank is located at the top of the interior of the dyeing machine housing. A through-hole is located inside the collection tank, extending through the dyeing machine housing and outwards, and is connected to a filter. A filter screen is installed inside the filter. A storage tank is connected to the side of the filter away from the collection tank. The storage tank is connected to the interior of the dyeing machine housing via a water pump. A cleaner is fixed to the filter. A connection port is provided on the filter, connecting to the interior of the cleaner. A movable rod slides within the cleaner, extending into the filter through the connection port. A rake claw is provided on the movable rod, extending towards the filter screen, with the end of the rake claw adhering to the surface of the filter screen.

[0009] By adopting the above technical solution, when a large amount of fiber debris accumulates on the filter screen surface, the operator can drive the movable rod to slide, causing the rod to move the rake claws across the filter screen surface. The ends of the rake claws push away the accumulated fiber debris, minimizing its accumulation and clogging, thus ensuring the filter's filtration efficiency. This allows for filter screen cleaning without disassembling the filter, making the operation convenient and quick.

[0010] Preferably, the rake claw is hinged to the movable rod, and the rake claw is also provided with an opening and closing component, which is used to drive the rake claw to rotate.

[0011] By adopting the above technical solution, when cleaning the filter screen, if the rake claw is located at one end of the filter screen, the opening and closing component drives the rake claw to rotate, preventing it from contacting the filter screen. Then, the rake claw slides to the other end of the filter screen with the movable rod. During this process, the rake claw does not contact and clean the fiber debris on the filter screen. When the rake claw reaches the other end of the filter screen, the opening and closing component drives the rake claw to rotate in the opposite direction, allowing it to re-contact the filter screen. Then, the rake claw slides in the opposite direction with the movable rod. During this process, the rake claw cleans the fiber debris on the filter screen. This ensures that the rake claw cleans the fiber debris in only one direction during the reciprocating sliding process, making it easier to concentrate the fiber debris.

[0012] Preferably, the opening and closing assembly includes a toggle block, an opening block, and a closing block. The toggle block is fixed at the end of the rake claw away from the filter screen. The opening block is fixed inside the filter and located on the side of the filter away from the cleaner. The closing block is fixed inside the cleaner. The toggle block moves between the opening block and the closing block. The toggle block can abut against the opening block and the closing block can also abut against the closing block.

[0013] By adopting the above technical solution, when the agitator block moves with the rake claw to abut against the opening block, the opening block pushes the agitator block, causing the rake claw to rotate to a state of contact with the filter screen. Then, the rake claw moves closer to the cleaner along with the movable rod, cleaning the surface of the filter screen and causing fiber debris to be scooped into the cleaner by the rake claw. When the agitator block moves with the rake claw to abut against the gathering block, the gathering block pushes the agitator block, causing the rake claw to rotate in the opposite direction to a state of no contact with the filter screen. Then, the rake claw moves away from the cleaner along with the movable rod, and the rake claw no longer cleans the surface of the filter screen, thus achieving automatic deflection of the rake claw.

[0014] Preferably, a limiting block is also fixedly connected to the movable rod. The limiting block is located on the side of the rake claw away from the cleaner, and the limiting block abuts against the side wall of the rake claw.

[0015] By adopting the above technical solution, the limiting block plays a limiting role for the rake claw, restricting the rotation angle of the rake claw, preventing the rake claw from rotating excessively, ensuring the positional accuracy of the rake claw when in contact with the filter screen, and applying a supporting force to the rake claw when cleaning the fiber debris on the filter screen, preventing the rake claw from being excessively deflected by the fiber debris.

[0016] Preferably, the cleaner has a brush plate fixed inside, the brush plate is provided with bristles, and the rake claw can be pressed into the bristles.

[0017] By employing the above technical solution, when the rake claws finish cleaning the filter screen and retract with the movable rod, the rake claws will press into the bristles. The bristles can remove the fiber debris adhering to the rake claws, ensuring the cleanliness of the rake claws for better cleaning of the filter screen next time.

[0018] Preferably, the ends of the bristles are bent to form barbs.

[0019] By adopting the above technical solution, the bristle tips are bent to form barbs. The barbs make it easier for the bristles to retain fiber debris on the rake claws and keep the fiber debris on the bristles. The fiber debris is not easy to fall off, which further ensures the cleanliness of the rake claws and continuously collects fiber debris, which helps to improve the continuous effectiveness of filter cleaning.

[0020] Preferably, the cleaner has a slag discharge port on its side wall that extends through the inside and outside of the cleaner. A mounting plate is detachably fixed inside the slag discharge port. The mounting plate is fixedly connected to the brush plate, and the brush plate can pass through the slag discharge port.

[0021] By adopting the above technical solution, when a lot of fiber debris accumulates on the bristles, the mounting plate can be removed from the slag discharge port, so that the brush plate can be taken out for bristle cleaning or replacement. The operation is convenient and helps to maintain a good cleaning effect on the bristles, ensuring the cleaning ability of the rake claws.

[0022] Preferably, the cleaner has an electric push rod fixed inside, and the output end of the electric push rod is fixedly connected to the movable rod.

[0023] By adopting the above technical solution, the electric push rod can stably and accurately push the movable rod to move without manual operation, reducing labor intensity and improving the automation and efficiency of filter cleaning.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By setting up a cleaner, a movable rod, and rake claws, the movable rod can drive the rake claws to slide on the surface of the filter screen to clean the fiber debris on the surface of the filter screen. The filter screen can be cleaned without disassembling the filter, ensuring the filtration effect of the filter screen;

[0026] 2. By setting a toggle block, an opening block, and a gathering block, the contact and separation between the rake claw and the filter screen are automatically controlled, so that the rake claw cleans the fiber debris in the same direction, which facilitates the collection of fiber debris and improves the cleaning and collection effect of fiber debris;

[0027] 3. By setting up bristles with barbs, brush plates, slag discharge ports and detachable mounting plates, it is convenient to clean the rake claws and retain the fiber debris accumulated on the bristles, making it easy to collect the fiber debris and ensuring the continuous cleaning ability and working stability of the device.

[0035] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0036] This application discloses a device for removing impurities from the liquid surface of a fabric dyeing machine. (Refer to...) Figure 1 and Figure 2 It includes a dyeing machine housing 1, and a collection tank 11 is provided at the top inside the dyeing machine housing 1. The collection tank 11 has a through hole 12 inside. When the dyeing machine is working, the fiber debris in the dye liquor will float to the surface of the dye liquor and then flow into the collection tank 11, which is flush with the surface of the dye liquor.

[0037] Reference Figure 3 and Figure 4 A through-hole 12 penetrates the outer casing 1 of the dyeing machine and extends to the outside of the outer casing 1, and is connected to a filter 2. A filter screen 21 is installed inside the filter 2. A storage tank 3 is connected to the side of the filter 2 away from the collection tank 11. A control valve is also connected to the pipe between the storage tank 3 and the filter 2. The storage tank 3 is connected to the interior of the dyeing machine outer casing 1 via a water pump 4. Fiber debris and other impurities enter the filter 2 through the through-hole 12 along with the dye liquor. After being filtered by the filter screen 21 inside the filter 2, the clean dye liquor enters the storage tank 3 and returns to the interior of the dyeing machine outer casing 1 under the action of the water pump 4.

[0038] Reference Figure 4 and Figure 5 A cleaner 5 is fixed to the top of the filter 2, and a connection port 22 is provided on the top of the filter 2 to connect to the interior of the cleaner 5. A movable rod 51 slides vertically inside the cleaner 5, and an electric push rod 57 is fixed inside the cleaner 5. The output end of the electric push rod 57 is fixedly connected to the movable rod 51 to control the sliding of the electric push rod 57. The movable rod 51 extends into the filter 2 through the connection port 22, and a rake 52 extending towards the filter screen 21 is rotatably mounted on the movable rod 51. The end of the rake 52 is in contact with the surface of the filter screen 21, and the edge of the end of the rake 52 in contact with the surface of the filter screen 21 needs to be rounded to prevent scratching the filter screen 21.

[0039] Reference Figure 5The bottom of the movable rod 51 is also fixedly connected to a limiting block 511 via a connecting bracket. The limiting block 511 is located on the side of the rake claw 52 away from the cleaner 5, and the limiting block 511 abuts against the side wall of the rake claw 52. Specifically, when the limiting block 511 abuts against the side wall of the rake claw 52, ​​the angle between the orientation of the rake claw 52 and the length direction of the movable rod is 90 degrees.

[0040] Reference Figure 4 The rake claw 52 is also equipped with an opening and closing assembly, which drives the rake claw 52 to rotate. Specifically, the opening and closing assembly includes a toggle block 521, an opening block 23, and a closing block 53. The toggle block 521 is fixed at the end of the rake claw 52 away from the filter screen 21. The toggle block 521 is a straight plate and is set at a 45-degree angle relative to the length direction of the movable rod 51. The opening block 23 is fixed inside the filter 2 and is located on the side of the filter 2 away from the cleaner 5. The closing block 53 is fixed inside the cleaner 5. The toggle block 521 moves between the opening block 23 and the closing block 53. The toggle block 521 can abut against the opening block 23 and can also abut against the closing block 53. The opening block 23 and the closing block 53 are round rods of equal diameter, and both the opening block 23 and the closing block 53 abut against the toggle block 521 on their peripheral walls.

[0041] When cleaning of filter screen 21 is required, the electric push rod 57 is activated, which drives the movable rod 51 to slide back and forth. The electric push rod 57 first moves the movable rod 51 upward. The rake claw 52 cleans the fiber debris on the surface of filter screen 21 and scoops the fiber debris into the cleaner 5. Then, the actuating block 521 abuts against the gathering block 53. Under the push of the gathering block 53, the actuating block 521 drives the rake claw 52 to deflect, and the rake claw 52 changes to a state where its end is not in contact with filter screen 21. Then, the movable rod 51 moves downward to reset. During this process, the rake claw 52 does not contact the fiber debris on filter screen 21. When the rake claw 52 moves to the bottom end near filter screen 21, the actuating block 521 abuts against the opening block 23. The opening block 23 pushes the actuating block 521, causing the rake claw 52 to rotate back to a state of contact with filter screen 21. At this time, the rake claw 52 abuts against the limiting block 511. This cycle repeats, allowing the rake claw 52 to clean the fiber debris in one direction (i.e. towards the cleaner 5), making it easier to collect the fiber debris.

[0042] To facilitate the collection of fiber debris, refer to Figure 4 and Figure 6 The cleaner 5 has a fixed brush plate 54 with bristles 55. A rake claw 52 can press into the bristles 55. The ends of the bristles 55 are bent to form barbs 551. The bristles 55 can be made of nylon. When the rake claw 52 presses into the bristles 55, the barbs 551 make it easier for the bristles 55 to retain fiber debris on the rake claw 52, ​​preventing the fiber debris from falling off and ensuring the cleanliness of the rake claw 52 while continuously collecting fiber debris.

[0043] To facilitate cleaning of fiber debris from brush bristles 55, refer to... Figure 4 The cleaner 5 has a slag discharge port 56 extending through the inside and outside of the cleaner 5 on its side wall. A mounting plate 561 is detachably fixed inside the slag discharge port 56. The mounting plate 561 is fixedly connected to the brush plate 54 via a connecting rod 562, and the brush plate 54 can pass through the slag discharge port 56. Specifically, the mounting plate 561 is fixed inside the slag discharge port 56 with bolts, and the mounting plate 561 seals the slag discharge port 56.

[0044] The implementation principle of the liquid surface impurity removal device for a dyeing machine according to an embodiment of this application is as follows: When the dyeing machine is working, fiber debris on the surface of the dye liquor flows into the collection tank 11 and enters the filter 2 through the through hole 12. After being filtered by the filter screen 21, the dye liquor enters the storage tank 3 and returns to the interior of the dyeing machine housing 1 under the action of the water pump 4.

[0045] When the filter screen 21 needs cleaning, the electric push rod 57 is activated, causing the movable rod 51 to reciprocate. When the movable rod 51 moves upward, the rake claw 52 contacts the filter screen 21, and the end of the rake claw 52 cleans the fiber debris and scoops it into the cleaner 5. In the cleaner 5, the rake claw 52, ​​carrying the fiber debris, presses it into the bristles 55. The barbs 551 on the bristles 55 can peel the fiber debris off the rake claw 52 and retain it. During this process, the actuating block 521 abuts against the gathering block 53, causing the rake claw 52 to deflect, so that when the movable rod 51 moves downward to its reset position, the rake claw 52 does not contact the filter screen 21. When the rake claw 52 moves to one end of the bottom of the filter screen 21, the actuating block 521 abuts against the opening block 23, causing the rake claw 52 to re-contact the filter screen 21. This cycle repeats, concentrating the fiber debris onto the bristles 55. When a large amount of fiber debris accumulates on the bristles 55, the mounting plate 561 can be removed, and the brush plate 54 can be taken out for cleaning or replacement.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
