Description

Technical Field

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

[0002] Pad dyeing is a method of dyeing fabrics. It involves briefly immersing the fabric in a dye bath, then pressing it with rollers to force the dye into the fabric's structure and gaps. Excess dye is then removed, resulting in a uniform distribution of dye on the fabric. Pad dyeing is primarily achieved using a pad dyeing machine, where the fabric undergoes immersion in the dye bath.

[0003] However, when existing pad dyeing machines are used to pad dye fabrics, the lint and other fibers adhering to the fabric are easily shed and left in the dye liquor. If there is too much lint in the dye liquor, it can easily lead to color defects in the fabric. Therefore, a filtration device for the dye liquor of the pad dyeing machine is needed. Summary of the Invention

[0004] To address the aforementioned shortcomings in the existing technology, this utility model provides a filtration device for dye liquor in a pad dyeing machine, which solves the problem that when existing pad dyeing machines are used to pad dye fabrics, lint and other lint adhering to the fabric are easily shed and left in the dye liquor. If there is too much lint in the dye liquor, it can easily lead to color defects in the fabric.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A filtration device for dye liquor in a pad dyeing machine includes a dye liquor tank, a pumping pump installed on the side of the dye liquor tank, a pumping pipe connected to the end of the pumping pump, a delivery pump installed on the side of the dye liquor tank, a delivery pipe connected to the end of the delivery pump, and a filter box connecting the pumping pipe and the delivery pipe.

[0007] A filter plate is installed inside the filter box, and a filter cylinder is installed between the filter plate and the inner wall of the filter box. A sieve cylinder is installed inside the filter cylinder. The surface of the sieve cylinder is evenly covered with sieve holes, and the surface of the filter cylinder is evenly covered with filter holes. The diameter of the filter holes is smaller than that of the sieve holes, which facilitates the filtration of fabric fibers from the dye liquor, reduces the frequency of dye liquor replacement, and avoids color defects in the fabric.

[0008] Furthermore, retaining rings are installed on the side walls of the filter plate and the inner walls of the filter box, and connecting pipes are installed at both ends of the filter cylinder. The connecting pipes can engage with the retaining rings, thereby facilitating the disassembly and cleaning of the filter cylinder and reducing the difficulty of the work.

[0009] Furthermore, sealing gaskets are installed at the connection points between the liquid extraction tube, the liquid delivery tube, and the filter box, thereby preventing dye leakage and contamination of the fabric dyeing environment.

[0010] Furthermore, a cover plate is detachably installed on the top surface of the filter box, which facilitates the removal of the cover plate and timely maintenance of the filter box. Attached Figure Description

[0017] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0019] Example:

[0020] like Figures 1-4 As shown, the present invention provides a filtration device for dye liquor in a dyeing machine, comprising a dye liquor tank 1, a pump 101 installed on the side of the dye liquor tank 1, a pump 102 connected to the end of the pump 101, a delivery pump 103 installed on the side of the dye liquor tank 1, a delivery pipe 104 connected to the end of the delivery pump 103, and a filter box 105 connecting the pump 102 and the delivery pipe 104.

[0021] A filter plate 201 is installed inside the filter box 105. A filter cylinder 202 is installed between the filter plate 201 and the inner wall of the filter box 105. A sieve cylinder 203 is installed inside the filter cylinder 202. The surface of the sieve cylinder 203 is evenly provided with sieve holes 204. The surface of the filter cylinder 202 is evenly provided with filter holes 205. The diameter of the filter holes 205 is smaller than that of the sieve holes 204, which facilitates the filtration of fabric fibers from the dye liquor, reduces the frequency of dye liquor replacement, and avoids color defects in the fabric.

[0022] The filter plate 201 is equipped with retaining rings 301 on its side wall and the filter box 105 on its inner wall. The filter cylinder 202 is equipped with connecting pipes 302 at both ends. The connecting pipes 302 can engage with the retaining rings 301, which makes it easy to disassemble the filter cylinder 202 for cleaning and reduces the difficulty of the work.

[0023] Sealing gaskets 4 are installed at the connection points of the liquid extraction pipe 102, the liquid delivery pipe 104 and the filter box 105, which can prevent the dye liquor from leaking and contaminating the dyeing environment of the fabric.

[0024] The top surface of the filter box 105 is detachably fitted with a cover plate 5, which facilitates the removal of the cover plate 5 and timely maintenance of the filter box 105.
