[0030] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0031] Embodiment 1: Please refer to Figures 1 to 10 :

[0032] The present utility model provides a dyeing and finishing wastewater recycling device, which includes a sedimentation and separation conveyor belt 2 installed inside a wastewater recycling and sedimentation tank 1. A conveyor belt driving member 3 is fixedly connected to the front surface of the wastewater recycling and sedimentation tank 1 by bolts. The conveyor belt driving member 3 drives the sedimentation and separation conveyor belt 2. An auxiliary jitter roller 4 is rotatably connected inside the wastewater recycling and sedimentation tank 1. The auxiliary jitter roller 4 is perpendicular to the front surface of the wastewater recycling and sedimentation tank 1. A roller driving member 5 is fixedly connected to the front surface of the wastewater recycling and sedimentation tank 1 by bolts. The rotating shaft of the roller driving member 5 is connected to the front end of the shaft body of the movable auxiliary jitter roller 4 through a coupling. A movable sewage tank 6 is movably connected to the bottom inside the wastewater recycling and sedimentation tank 1. The wastewater recycling and sedimentation tank 1 is a cuboid tank body. A lower separation chamber 101 is provided below the wastewater recycling and sedimentation tank 1. The lower separation chamber 101 communicates with the space inside the wastewater recycling and sedimentation tank 1. A limit isolation strip 102 is fixedly connected to the front surface and the rear surface inside the wastewater recycling and sedimentation tank 1 respectively. The inside of the wastewater recycling and sedimentation tank 1 is used for storing dyeing and finishing wastewater. The bottom of the wastewater recycling and sedimentation tank 1 extends to form a lower separation chamber 101. The width of the lower separation chamber 101 is greater than the width of the wastewater recycling and sedimentation tank 1. It extends straight outwards at the bottom of the wastewater recycling and sedimentation tank 1. The upper surface of the lower separation chamber 101 is in contact with the separation bar 204, which can achieve an isolation effect and prevent the sewage inside the wastewater recycling and sedimentation tank 1 from leaking through the gaps on both sides above the lower separation chamber 101.

[0033] In the embodiment of the present disclosure, a separation belt lower support plate 103 is welded to the inner front surface and the inner rear surface of the lower separation chamber 101 respectively. A support plate roller 104 is rotatably connected to the upper surface of the separation belt lower support plate 103. Sewage tank support plates 105 are welded to the lower edges of the inner front surface and the inner rear surface of the lower separation chamber 101 respectively. The separation belt lower support plate 103 and the limit isolation strip 102 are respectively attached to the inner surface and the outer surface of the conveyor belt body 201, and the conveyor belt body 201 is closely attached, so as to prevent the water inside the wastewater recovery sedimentation tank 1 from leaking through the front edge and the rear edge of the conveyor belt body 201. By providing the support plate roller 104, the friction generated during the movement of the conveyor belt body 201 can be reduced, and the running resistance of the sediment separation conveyor belt 2 can be alleviated.

[0034] In the embodiment of the present disclosure, the sediment separation conveyor belt 2 includes a conveyor belt body 201, a driving support cylinder 202 and a driven support cylinder 203. The driving support cylinder 202 is located inside the wastewater recovery sedimentation tank 1, and the support shaft of the driving support cylinder 202 is rotatably connected to the tank wall of the wastewater recovery sedimentation tank 1. The axis of the driving support cylinder 202 is perpendicular to the front surface of the wastewater recovery sedimentation tank 1. The front end of the shaft body of the driving support cylinder 202 is connected to the rotating shaft of the conveyor belt driving member 3 through a coupling. The conveyor belt body 201 is installed on the driving support cylinder 202 and the driven support cylinder 203. The upper surface of the conveyor belt body 201 is closely attached to the lower surface of the limit isolation strip 102. The inner surface of the conveyor belt body 201 is in rolling connection with the support plate roller 104. The outer surface of the conveyor belt body 201 is fixedly connected with a separation bar 204, and the separation bar 204 is perpendicular to the front surface of the wastewater recovery sedimentation tank 1 and the outer surface of the conveyor belt body 201. By driving the driving support cylinder 202 to rotate through the conveyor belt driving member 3, the conveyor belt body 201 is driven to rotate by the friction between the driving support cylinder 202 and the conveyor belt body 201, and through the support of the driven support cylinder 203, the conveyor belt body 201 is kept highly tensioned, so as to prevent the sediment separation conveyor belt 2 from deforming under the action of water pressure.

[0035] In the embodiments of the present disclosure, the driven support cylinder 203 is located inside the wastewater recovery sedimentation tank 1, and the driven support cylinder 203 is parallel to the driving support cylinder 202. The support shaft of the driven support cylinder 203 is rotatably connected to the pool wall of the wastewater recovery sedimentation tank 1. The axis of the driven support cylinder 203 is perpendicular to the front surface of the wastewater recovery sedimentation tank 1, and the driven support cylinder 203 and the driving support cylinder 202 have the same height. During the operation of the sedimentation separation conveyor belt 2, the rotation of the conveyor belt body 201 drives the separation bar 204 to move horizontally, so that the sediment and impurities deposited on the surface of the conveyor belt body 201 are conveyed to one side along with the conveyor belt body 201 and the separation bar 204, and are output through the right end of the lower separation chamber 101. The impurities on the outer surface of the conveyor belt body 201 can be turned downward along with the movement of the sedimentation separation conveyor belt 2, so that the outer surface of the conveyor belt body 201 faces downward and automatically falls into the movable sewage tank 6 for concentration, realizing the function of automatic collection of sediment.

[0036] Embodiment 2, on the basis of Embodiment 1, the auxiliary jitter roller 4 is attached to the inner surface of the conveyor belt body 201, and the outer surface of the auxiliary jitter roller 4 is provided with a convex pattern structure; when the auxiliary jitter roller 4 is driven to rotate by the roller driving member 5, since the outer surface of the auxiliary jitter roller 4 is provided with convex strips, during the rotation of the auxiliary jitter roller 4, the convex strips frequently collide with the inner surface of the conveyor belt body 201, causing the conveyor belt body 201 to jitter, so that the sediment and impurities on the outer surface of the conveyor belt body 201 are more likely to be separated from the lower separation chamber 101.

[0037] The working principle of this embodiment: First, the dyeing and finishing wastewater is conveyed into the wastewater recovery sedimentation tank 1 and stored in the wastewater recovery sedimentation tank 1 for static settlement to precipitate the wastewater. After the wastewater is precipitated, the impurities and flocs in it fall on the upper surface of the conveyor belt body 201. At this time, the conveyor belt driving member 3 is started to slowly rotate the conveyor belt driving member 3, driving the sedimentation separation conveyor belt 2 to move slowly, so that the conveyor belt body 201 slowly rotates in the clockwise direction, and the rotation speed is controlled not to be higher than 1 m / min, so that the sediment in the wastewater passes through the side channel of the lower separation chamber 101 and is discharged from its right end. By adjusting the sedimentation separation conveyor belt 2, the precipitated impurities can be transferred out of the tank body. The impurities on the outer surface of the conveyor belt body 201 can be turned downward along with the movement of the sedimentation separation conveyor belt 2, so that the outer surface of the conveyor belt body 201 faces downward and automatically falls into the movable sewage tank 6 for concentration. At the same time, the wastewater with too high impurity concentration at the bottom of the tank body can be discharged synchronously, realizing the automatic cleaning of sediment. The outer surface of the conveyor belt body 201 located outside the wastewater recovery sedimentation tank 1 can also be cleaned by a brush, thereby improving the cleaning efficiency and cleaning convenience of the dyeing and finishing wastewater treatment device.
