[0002] With the booming development of the textile printing and dyeing industry, while creating huge economic benefits, printing and dyeing wastewater has also had a significant impact on the environment. Printing and dyeing wastewater is characterized by large volume, large fluctuations, poor biodegradability, and high color intensity. It contains a large number of complex chemical substances. Strengthening research on wastewater treatment in the printing and dyeing industry, improving treatment efficiency, and expanding water-saving measures are of positive practical significance. Printing and dyeing wastewater is a general term for all kinds of wastewater discharged during the production process of various textile printing and dyeing enterprises. The harm of printing and dyeing wastewater to the environment and human beings has attracted increasing attention.

[0003] Patent CN221207054U discloses a wastewater treatment device for knitting and dyeing. This utility model discloses a wastewater treatment device for knitting and dyeing, including a fixed filter box. The fixed filter box has connecting ports on both its left and right sides. Inside these ports, an inlet pipe and an outlet pipe are respectively connected at different heights. A fixed top plate is detachably connected to the top of the fixed filter box, and an installation frame is fixedly installed at the bottom of the fixed top plate. In this solution, by setting up the installation frame, filter side plates, fixed top plate, connecting holes, and strip-shaped slots, and utilizing the cooperation of these components, the operator can fully filter and block the flocculent cotton lint sediment inside the textile wastewater discharged through the inlet pipe via the filter side plates within the installation frame inside the fixed filter box.

[0004] However, the seal between the filter side plate and the mounting frame cannot be well guaranteed, and there will be gaps between the filter side plate and the mounting frame. Some impurities will flow out from the gaps between the filter side plate and the mounting frame, affecting the filtration effect. Utility Model Content

[0005] The purpose of this utility model is to provide a dyeing and printing wastewater treatment device, in which the sealing ring abuts against the bottom surface of the fixed groove, thereby increasing the sealing between the sealing ring and the fixed groove and preventing wastewater from flowing out from the gap between the filter plate and the fixed groove.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dyeing and printing wastewater treatment device, comprising:

[0007] A filter housing, wherein the filter housing is provided with an upward-facing filter chamber;

[0008] A fixed frame is fixed inside the filter chamber, and a fixing groove is provided on one side of the fixed frame;

[0009] A filter plate is provided with a plurality of filter holes. A sealing ring is fixed on one side of the filter plate. The filter plate is detachably inserted into the fixing groove, and the sealing ring abuts against the bottom surface of the fixing groove.

[0010] A limiting device is provided, which can be operably switched between a limiting position and an unlocking position. In the limiting position, the limiting device limits the filter plate within the fixing groove. In the unlocking position, the filter plate can be removed from the fixing groove.

[0011] Furthermore, the limiting device includes:

[0012] Two fixing seats are fixed to the inner wall of the filter cavity;

[0013] A rotating shaft is rotatably connected between the two fixed seats;

[0014] A limiting protrusion is fixed on the rotating shaft. The limiting protrusion has a limiting end. When in the limiting position, the limiting end abuts against the side of the filter plate opposite to the sealing ring. When in the unlocking position, the limiting end moves away from the side of the filter plate opposite to the sealing ring.

[0015] Furthermore, a fixed seat extends from the upper end of the rotating shaft, and a positioning rod is fixed to the upper end of the rotating shaft. A positioning block corresponding to the positioning rod is fixed to the upper side of the filter box. The positioning block is provided with a positioning threaded hole, and a positioning bolt is internally threaded into the positioning threaded hole.

[0017] Furthermore, the limiting device is provided in two sets, with the two limiting devices located at both ends of the filter plate.

[0018] Furthermore, the filter plate is provided with a sealing groove, and one end of the sealing ring is inserted into the sealing groove.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) The dyeing and printing wastewater enters the filter chamber through the inlet, and then is discharged from the outlet after being filtered by the filter plate, thus realizing the recycling of wastewater. Since the sealing ring abuts against the bottom surface of the fixed groove, it can increase the sealing between the sealing ring and the fixed groove, and prevent wastewater from flowing out from the gap between the filter plate and the fixed groove.

[0021] (2) The limit protrusion can be rotated by rotating the rotating shaft, so that it can be quickly switched between the limit position and the unlock position, which is very convenient;

[0022] (3) During the process of screwing the positioning bolt into the positioning rod, the rotating shaft can be driven to rotate by squeezing the positioning surface. During the rotation of the rotating shaft, the limiting end of the limiting protrusion will rotate towards the filter plate side, thereby pressing the filter plate into the fixed groove. At this time, it is in the limiting position, and the sealing ring is in the compressed state, which has a good sealing effect and the limiting is very convenient.

[0023] (4) Simply rotate the locking nut to make it abut against the outer side plate of the positioning block, thereby locking the positioning bolt. Attached Figure Description

[0030] 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.

[0031] Please see Figures 1-5 This utility model provides a technical solution for a dyeing and printing wastewater treatment device.

[0032] A dyeing and printing wastewater treatment device, comprising:

[0033] The filter box 1 has an upward-facing filter chamber 2, with an inlet 19 and an outlet 20 at each end.

[0034] A fixed frame 3 is fixed inside the filter chamber 2, and a fixing groove 4 is provided on one side of the fixed frame 3;

[0035] The filter plate 5 has several filter holes 6 and a sealing ring 7 is fixed on one side of the filter plate 5. The filter plate 5 is detachably inserted into the fixing groove 4 and the sealing ring 7 abuts against the bottom surface of the fixing groove 4.

[0036] The limiting device can be operably switched between a limiting position and an unlocking position. In the limiting position, the limiting device limits the filter plate 5 within the fixing groove 4. In the unlocking position, the filter plate 5 can be removed from the fixing groove 4.

[0037] The dyeing and printing wastewater enters the filter chamber 2 through the inlet 19, and then is discharged from the outlet 20 after being filtered by the filter plate 5. Because the sealing ring 7 abuts against the bottom surface of the fixing groove 4, the sealing performance between them is increased, preventing wastewater from flowing out through the gap between the filter plate 5 and the fixing groove 4. When it is necessary to disassemble the filter plate 5 for cleaning, the limiting device switches to the unlocked position, allowing the filter plate 5 to be removed from the fixing groove 4.

[0038] The limiting device includes:

[0039] Two fixing seats 8 are fixed to the inner wall of the filter chamber 2;

[0040] Rotating shaft 9 is rotatably connected between two fixed seats 8;

[0041] The limiting protrusion 10 is fixed on the rotating shaft 9. The limiting protrusion 10 is provided with a limiting end 11. When in the limiting position, the limiting end 11 abuts against the side of the filter plate 5 facing away from the sealing ring 7. When in the unlocking position, the limiting end 11 leaves the side of the filter plate 5 facing away from the sealing ring 7.

[0042] By rotating the rotating shaft 9, the limiting protrusion 10 can be rotated, thus enabling quick switching between the limiting position and the unlocking position, which is very convenient.

[0043] The upper end of the rotating shaft 9 extends to a fixed seat 8 located above. A positioning rod 12 is fixed to the upper end of the rotating shaft 9. A positioning block 13 corresponding to the positioning rod 12 is fixed to the upper side of the filter box 1. The positioning block 13 is provided with a positioning threaded hole 14. A positioning bolt 15 is internally threaded into the positioning threaded hole 14. A positioning surface 16 is provided on the positioning rod 12. When in the limited position, the end of the positioning bolt 15 abuts against the positioning surface 16.

[0044] The position of the positioning rod 12 can be restricted by rotating the positioning bolt 15. As the positioning bolt 15 is screwed into the positioning rod 12, it compresses the positioning surface 16, causing the rotating shaft 9 to rotate. During this rotation, the limiting end 11 of the limiting protrusion 10 rotates towards the filter plate 5, thus pressing the filter plate 5 tightly into the fixing groove 4. At this point, it is in the limited position, and the sealing ring 7 is compressed, achieving a good sealing effect. When it is necessary to disassemble the filter plate 5, simply rotate the positioning screw in the opposite direction. After rotating to a certain position, the positioning rod 12 can be freely rotated, allowing the limiting protrusion 10 to rotate away from the filter plate 5, at which point the filter plate 5 can be removed.

[0045] To lock the positioning bolt 15, a locking nut 17 is threaded onto the positioning bolt 15. When it is not necessary to rotate the positioning bolt 15, it is only necessary to rotate the locking nut 17 so that the locking nut 17 abuts against the outer side plate of the positioning block 13, thereby locking the positioning bolt 15.

[0046] There are two sets of limiting devices, which are located at both ends of the filter plate 5, so that both ends of the filter plate 5 can be pressed tightly, resulting in a better pressing effect and ensuring the stability of the filter plate 5 during operation.

[0047] The filter plate 5 is provided with a sealing groove 18. One end of the sealing ring 7 is inserted into the sealing groove 18, and the other end protrudes from the sealing groove 18, thereby enabling the sealing ring 7 to be installed on the filter plate 5. When the sealing ring 7 needs to be replaced, it can be removed from the sealing groove 18.

[0048] The fixing frame 3 can be fixed inside the filter chamber 2 by welding, thus firmly fixing the fixing frame 3 inside the filter chamber 2. Welding is not only simple and quick, but also provides stable connection strength, ensuring that the fixing frame 3 will not loosen or shift during use.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
