Description

Technical Field

[0001] The utility model belongs to the field of curtain printing and dyeing, and more specifically, relates to a curtain fabric printing and dyeing wastewater recycling device. Background Art

[0002] Printing and dyeing wastewater treatment is a process of purifying, removing color and cleaning the wastewater generated during the curtain fabric printing and dyeing production process through physical filtration and biochemical decomposition, ensuring that the purified printing and dyeing water can be recycled to reduce damage and pollution to the water resource environment. At present, the treatment of printing and dyeing wastewater requires physical barrier filtration of fiber impurities and sand and gravel substances mixed in the printing and dyeing wastewater through a screen, and then the oxidant is mixed into the filtered wastewater for soaking and dissolving to remove dyes and other substances. However, during the long-term filtration use of the screen for printing and dyeing wastewater, fiber impurities and sand and gravel will gradually accumulate on the sides and mesh of the screen. Since the screen itself does not have the cleaning ability, in order to ensure the water permeability and filtration performance of the screen, it is necessary to regularly shut down the wastewater treatment equipment and let workers use a small brush to repeatedly clean the impurities filtered on the surface of the screen. It can be seen that traditional manual cleaning of screen impurities is time-consuming and labor-intensive, and the cleaning efficiency is low. In addition, after the solid oxidant enters the printing and dyeing wastewater, some of the solid oxidant is deposited at the bottom of the printing and dyeing wastewater pool by gravity, causing the printing and dyeing wastewater in the middle part of the pool and the surface wastewater to be unable to fully contact the oxidant, resulting in poor dye decolorization effect.

[0023] In the disclosed embodiment, the outer side surface of the cleaning cylinder 13 is densely covered with a large number of plastic fiber brush heads, and the filter screen plate 9 is scraped and cleaned by the brush heads of the cleaning cylinder 13 .

[0024] In the embodiment of the present disclosure, the center part of the upper side surface of the filter screen plate 9 is densely covered with a large number of micropores that pass through from top to bottom. The micropores of the filter screen plate 9 are used to block and filter the dye impurities and sand and gravel mixed in the printing and dyeing wastewater. The upper side surface of the filter screen plate 9 is provided with convex plates near the left and right ends. Each set of convex plates is provided with a long through-groove structure that passes through left and right.

[0025] In the disclosed embodiment, the bracket 8 is a rectangular frame structure that runs through the top and bottom. The upper side surface of the bracket 8 frame structure is a sloped structure that tilts backward at an angle of 15 degrees. The filter screen plate 9 is connected to the sloped structure on the upper side surface of the bracket 8 by bolts, so that the filter screen plate 9 tilts backward at an angle of 15 degrees, ensuring that the printing and dyeing water that has not penetrated into the micropores of the filter screen plate 9 moves backward along the filter screen plate 9 under the influence of gravity, thereby preventing the printing and dyeing water from overflowing from the filter screen plate 9.

[0026] In the embodiment of the present disclosure, there are two groups of sliders 16, and the sliders 16 are symmetrically distributed on the left and right. The upper side surface of each group of sliders 16 is provided with a through hole that passes through from top to bottom.

The outer side surface of the threaded rod 21 is threadedly engaged with the threaded through hole of the right slider 16. The front side surface of the slider 16 on the left is provided with a through hole that passes through from front to back. The guide rod 22 is inserted into the through hole of the left slider 16. During the rotation process, the threaded rod 21 drives the slider 16 to move forward and backward along the guide rod 22. The slider 16 drives the shovel plate 12 hinged on the front side of the beam 27 through the connecting block 15 to move synchronously with the filter screen plate 9, thereby completing the shovel cleaning work of the sand and gravel on the filter screen plate 9.

[0027] In the embodiment of the present disclosure, there are two groups of connecting blocks 15, and the lower side of each group of connecting blocks 15 is provided with a boss. The boss on the lower side of the connecting block 15 is inserted into the through hole on the upper side of the slider 16, so that the connecting block 15 moves up and down along the through groove of the slider 16, ensuring that the beam frame 27 slides obliquely along the filter screen plate 9.

[0028] In the disclosed embodiment, six groups of arc-shaped curved plates are provided on the outer side of the stirring rack 25, and the arc-shaped curved plates are distributed in a circular array around the central axis of the stirring rack 25. The arc-shaped curved plates of the stirring rack 25 stir the wastewater in the wastewater pool 1, so that the solid oxidant deposited at the bottom of the wastewater pool 1 rolls upward with the water flow, so that the solid oxidant and the printing and dyeing wastewater are fully fused and contacted.

[0029] The specific usage and function of this embodiment are as follows:

[0030] When the utility model is performing purification and recycling of printing and dyeing wastewater, the printing and dyeing wastewater flows into the wastewater pool 1 from the micropores on the upper side of the filter screen plate 9, and the dye fiber impurities and sand and gravel materials in the printing and dyeing wastewater are blocked on the upper side of the filter screen plate 9. Then, an oxidant is injected from the injection slot 18, and the oxidant falls into the interior of the wastewater pool 1 through the through slot on the rear side of the wastewater pool 1. The controller 19 controls the stirring motor 23 to drive the rotating rod 24 on the rear side to rotate, and the rotating rod 24 drives the active sleeve 6 to rotate, and the active sleeve 6 drives the driven sleeve 7 to rotate through the belt 5. The driven sleeve 7 drives the rotating rod 24 on the front side to rotate synchronously, and the two sets of rotating rods 24 drive the stirring frame 25 installed on the outer side to rotate. The arc-shaped bent plate of the stirring frame 25 stirs the printing and dyeing wastewater and shovels the deposited oxidant at the bottom of the wastewater tank 1 to move upward, so that the oxidant and the printing and dyeing wastewater are fully mixed and the printing and dyeing wastewater is decolorized and purified. If it is necessary to clean the filter screen plate 9, the controller 19 controls the cleaning motor 20 to drive the threaded rod 21 to rotate. Since the outer side of the threaded rod 21 is threadedly engaged with the thread of the slider 16 on the right side, the cleaning motor 20 drives the threaded rod 21 to rotate. In the through hole, the threaded rod 21 drives the slider 16 on the right to pull the connecting block 15 to move synchronously, and the connecting block 15 drives the beam 27 to move forward along the filter screen plate 9, and the beam 27 drives the hinged shovel plate 12 on the front side to move forward. Since the lower side of the pressure plate frame 11 is in contact with the upper side of the shovel plate 12, the pressure plate frame 11 limits the upward flipping of the shovel plate 12, and the shovel plate 12 is in contact with the upper side of the filter screen plate 9 to collect the sand and gravel materials by shoveling. The beam 27 drives the support rod 26 connected to the rear side to move forward synchronously, and the support rod 26 The gear 14 is driven to move forward. Since the gear 14 is engaged with the rack structure on the upper side of the filter screen plate 9, the gear 14 drives the support rod 26 to rotate during the forward movement. The support rod 26 drives the brush on the outer side of the cleaning cylinder 13 to scrape the fiber impurities on the upper side of the filter screen plate 9. When the shovel plate 12 moves to the front end of the filter screen plate 9, since the shovel plate 12 is hinged to the beam 27, the shovel plate 12 flips downward, and the sand and gravel materials fall from the shovel plate 12 into the waste basket 3 by gravity, completing the cleaning work of the filter screen plate 9.

[0031] All of the above components are installed, connected, or configured using common mechanical methods, such as welding, threaded connections, and screw connections. The specific structures, models, and coefficients of all components are proprietary technologies, and any method that can achieve the desired effect may be employed. The controller 19, cleaning motor 20, and stirring motor 23 are all commercially available components. Upon purchase, they can be connected and used in accordance with the included instruction manual, so further description is omitted.
