DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention.

[0036] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0039] Example 1

[0040] This embodiment proposes a polyester low-elastic silk printing and dyeing wastewater treatment device, such as Figure 1 and Figure 2 As shown, it includes a sewage treatment pool 1, an air flotation pool 2 and a coagulation pool 3 are opened inside the sewage treatment pool 1, a guide plate is fixedly installed inside the sewage treatment pool 1, and the guide plate is located between the air flotation pool 2 and the coagulation pool 3. A dissolved air releaser 7 is fixedly installed inside the coagulation pool 3. By adding chemicals into the air flotation pool 2, small particles in the printing and dyeing wastewater in the air flotation pool 2 are condensed, and the dissolved air releaser 7 is used for flotation separation.

[0041] like Figure 4 and Figure 5 As shown, a pre-treatment component 4 is provided at the head of the sewage treatment tank 1, and the pre-treatment component 4 includes a secondary connecting pipe 43, one end of the secondary connecting pipe 43 is fixedly installed with a main pipeline 41, and the other end of the secondary connecting pipe 43 is connected to the flotation tank 2 inside the sewage treatment tank 1, and a spiral guide plate 42 is fixedly installed inside the main pipeline 41. Printing and dyeing wastewater flows along the spiral guide plate 42 inside the main pipeline 41. The printing and dyeing wastewater in the main pipeline 41 does not exceed one half of the volume of the main pipeline 41, and the printing and dyeing wastewater flows spirally along the spiral guide plate 42.

[0042] A filter cartridge 44 is fixedly installed inside the auxiliary connecting pipe 43. The filter cartridge 44 adopts a trumpet-shaped structure and has a filter hole area and a non-filter hole area on the filter cartridge 44. The non-filter hole area is located at the bottom of the filter cartridge 44 and close to the sewage treatment tank 1. The diameter of the filter cartridge 44 gradually increases. The printing and dyeing wastewater passes through the filter cartridge 44 to filter out large objects in the wastewater, such as fiber fragments and agglomerated pulp. After the limited fragments and agglomerated pulp are intercepted by the filter cartridge 44, the printing and dyeing wastewater continues to flow along the auxiliary connecting pipe 43 due to inertia. The limited fragments and agglomerated pulp on the outer wall of the filter cartridge 44 are driven by the printing and dyeing wastewater to continue moving, thereby bringing the fiber fragments and agglomerated pulp to the tail end of the filter cartridge 44.

[0043] When the printing and dyeing wastewater flows through the filter holes along the tangential direction of the filter cartridge 44, the fluid flow rate on the side of the filter hole close to the water flow is relatively fast and the pressure is relatively low; while the fluid flow rate on the other side of the filter hole, which is usually behind the blockage, is relatively slow and the pressure is high, resulting in a pressure difference from the side with high pressure to the side with low pressure, that is, in the direction of water flow, so the blockage in the filter holes of the filter cartridge 44 is brought out.

[0044] Furthermore, since the printing and dyeing wastewater does not directly impact the filter cartridge 44 for filtration, it takes a long time for the printing and dyeing wastewater to move from the outside of the filter cartridge 44 to the inside, resulting in a slow filtration process. Therefore, the fiber fragments and agglomerated slurry clog the filter cartridge 44 to a shallow depth, resulting in a low adhesion force between the fiber fragments and agglomerated slurry and the filter pores of the filter cartridge 44, allowing the printing and dyeing wastewater to remove the clogged materials from the filter pores of the filter cartridge 44. Furthermore, since the printing and dyeing wastewater does not directly impact the filter cartridge 44 for filtration, the impact force exerted by the printing and dyeing wastewater on the filter cartridge 44 is small, thereby extending the service life of the filter cartridge 44.

[0045] like Figure 3 and Figure 5 As shown, a gathering plate 46 is fixedly mounted on the outer wall of the filter cartridge 44. Gathering plate 46 is located above the axis of the filter cartridge 44. The top of gathering plate 46 is fixedly connected to the auxiliary connecting pipe 43. Gathering plate 46 adopts a spiral structure with a sixth of a turn, and its cross-sectional area gradually decreases from the opening to the tail end. A gathering tube 48 is fixedly mounted inside the auxiliary connecting pipe 43. Gathering tube 48 passes through the filter cartridge 44. The outer curved surface of gathering tube 48 is fixedly connected to gathering plate 46. An opening is formed at the connection between gathering tube 48 and gathering plate 46.

[0046] The fiber fragments and agglomerated slurry are diverted through the gathering plate 46 and introduced into the gathering cylinder 48. At the same time, the printing and dyeing wastewater flows at the connection between the gathering plate 46 and the filter cylinder 44 and enters the interior of the filter cylinder 44. The filtered printing and dyeing wastewater is collected through the non-filter hole area at the bottom of the filter cylinder 44 and near the tail end, and is diverted into the interior of the sewage treatment tank 1.

[0047] A support cylinder 45 is fixedly installed on the end of the filter cartridge 44 with a smaller diameter, and the support cylinder 45 is fixedly connected to the spiral guide plate 42. A support ring 47 is fixedly installed on the end of the filter cartridge 44 with a larger diameter, and the outer arc surface of the support ring 47 is fixedly connected to the auxiliary connecting pipe 43.

[0048] In this embodiment, the printing and dyeing wastewater is guided by the spiral guide plate 42 to make the printing and dyeing wastewater flow in a spiral manner. The printing and dyeing wastewater passes through the filter cartridge 44 to filter out large objects in the wastewater. The printing and dyeing wastewater continues to flow along the auxiliary connecting pipe 43 due to inertia. The fiber fragments and agglomerated slurry on the outer wall of the filter cartridge 44 are driven by the printing and dyeing wastewater to continue moving, thereby bringing the fiber fragments and agglomerated slurry to the tail end of the filter cartridge 44. At the same time, when the printing and dyeing wastewater flows through the filter holes along the tangential direction of the filter cartridge 44, the blockages in the filter holes of the filter cartridge 44 are brought out.

[0049] Example 2

[0050] Based on Example 1, this example proposes a polyester low-elastic silk printing and dyeing wastewater treatment device, such as Figure 5 and Figure 6 As shown, the interior of the filter cartridge 44 is provided with a discharge assembly 5, which includes a three-part support plate 52. The interior of the filter cartridge 44 is fixedly mounted with the three-part support plate 52, and the side of the three-part support plate 52 is rotatably connected to the impeller 51, as shown in FIG. Figure 8 As shown, a vertical spiral blade 56 for conveying fiber debris and agglomerated slurry in the printing and dyeing wastewater is rotatably connected to the interior of the gathering cylinder 48 , and a transmission member is provided between the impeller 51 and the vertical spiral blade 56 .

[0051] The tail end of the gathering plate 46 faces the vertical spiral blade 56. An inclined discharge slide 58 is fixedly installed on the outer arc surface of the gathering cylinder 48 near the top. A discharge port 57 is provided at the connection between the gathering cylinder 48 and the discharge slide 58. A negative pressure exhaust pump is fixedly installed at the connection between the discharge slide 58 and the gathering cylinder 48 to assist in extracting fiber fragments and agglomerated slurry. The filtered printing and dyeing wastewater impacts the impeller 51, causing the impeller 51 to rotate. The impeller 51 uses a transmission member to rotate the vertical spiral blade 56, driving the fiber fragments and agglomerated slurry in the gathering cylinder 48 upward. After the fiber fragments and agglomerated slurry are transported to the discharge port 57, the fiber fragments and agglomerated slurry are discharged along the discharge slide 58. Since the vertical spiral blade 56 is vertical, the water in the fiber fragments and agglomerated slurry flows down along the vertical spiral blade 56 due to gravity.

[0052] like Figure 7As shown, the transmission member includes a first bevel gear 53, a second bevel gear 54 and a rotating rod 55. The first bevel gear 53 is fixedly mounted on the end of the rotating shaft of the impeller 51, and the center of the vertical spiral piece 56 is fixedly connected to the rotating rod 55. The second bevel gear 54 is fixedly mounted on the end of the rotating rod 55. The first bevel gear 53 is meshed with the second bevel gear 54. The first bevel gear 53 and the second bevel gear 54 are both located inside the three-part support plate 52.

[0053] The impeller 51 drives the first bevel gear 53 to rotate. Since the first bevel gear 53 and the second bevel gear 54 are engaged, the second bevel gear 54, the rotating rod 55 and the vertical spiral blade 56 rotate synchronously. The vertical spiral blade 56 is used to lift and remove fiber fragments and agglomerated pulp.

[0054] In this embodiment, the filtered printing and dyeing wastewater is used to impact the impeller 51 to make it rotate, so that the vertical spiral blades 56 rotate to lift the fiber fragments and agglomerated slurry in the gathering cylinder 48 to the discharge slide 58 and discharge them. Since the vertical spiral blades 56 are vertical, the water in the fiber fragments and agglomerated slurry flows down along the vertical spiral blades 56 due to gravity to separate solids and liquids, thereby preventing the fiber fragments and agglomerated slurry from accumulating in the gathering cylinder 48 and affecting the filtration of the filter cylinder 44.

[0055] Example 3

[0056] Based on the above embodiment 1 or embodiment 2, this embodiment proposes a polyester low-elastic silk printing and dyeing wastewater treatment device, such as Figure 9 As shown, a treatment control component 6 is fixedly installed at one end of the mainstream pipe 41 away from the auxiliary connecting pipe 43. The treatment control component 6 includes a wastewater inlet pipe 61. The end of the wastewater inlet pipe 61 is fixedly connected to the mainstream pipe 41. A push-type flow rate valve 62 is fixedly installed in the middle of the wastewater inlet pipe 61. The inside of the wastewater inlet pipe 61 is rotatably connected to a shock receiving plate 63. A reset counterweight block 64 is fixedly installed at the bottom end of the shock receiving plate 63. An adjustment part is provided between the reset counterweight block 64 and the push-type flow rate valve 62.

[0057] The diameter of the wastewater inlet pipe 61 is one-third of the diameter of the mainstream pipe 41, so the printing and dyeing wastewater flowing in the mainstream pipe 41 does not exceed one-half of the volume of the mainstream pipe 41. The flow rate of the printing and dyeing wastewater in the wastewater inlet pipe 61 is controlled by the push-type flow rate valve 62 so that the printing and dyeing wastewater still has inertia after flowing out of the mainstream pipe 41 and can maintain spiral flow. At the same time, the flow rate of the printing and dyeing wastewater is maintained within a fixed range to avoid excessive impact of the printing and dyeing wastewater on the filter cartridge 44, causing deformation of the filter cartridge 44 and affecting its filtering effect.

[0058] like Figure 10As shown, a guide support plate 67 is fixedly installed at the bottom of the wastewater inlet pipe 61, and an adjustment rod 66 is slidably connected to the inside of the guide support plate 67. A wedge block 68 is fixedly installed at the end of the adjustment rod 66. The inclined surface of the wedge block 68 contacts the pressing device of the press-type flow rate valve 62. An avoidance component is provided between the end of the adjustment rod 66 and the reset counterweight block 64.

[0059] Through the cooperation of the impacted plate 63 and the reset counterweight 64, the impacted plate 63 can be reset after being impacted by the printing and dyeing wastewater. The deflection of the impacted plate 63 drives the reset counterweight 64 to deflect. The reset counterweight 64 uses the intermediate plate 65 and the sliding column to drive the adjustment rod 66 to move, adjust the position of the wedge block 68 of the guide support plate 67, and use the inclined surface of the wedge block 68 to squeeze the pressing device of the press-type flow rate valve 62 to adjust the flow rate of the printing and dyeing wastewater in the press-type flow rate valve 62.

[0060] At the same time, if the content of fiber debris and agglomerated pulp in the printing and dyeing wastewater is high, the deflection angle of the impact plate 63 is large, at this time the flow velocity of the printing and dyeing wastewater is reduced, and the relative velocity between the printing and dyeing wastewater and the filter cartridge 44 is avoided, so as to improve the filtering effect.

[0061] The avoidance assembly includes a middle plate 65 and a sliding post. The middle plate 65 is fixedly mounted on the side of the reset counterweight 64 facing the push-type flow rate valve 62. A vertical slot is defined in the middle of the middle plate 65, and the sliding post slides within the slot. Both ends of the sliding post are fixedly connected to the adjustment rod 66. The movement of the reset counterweight 64 placed in the avoidance assembly is hindered by the adjustment rod 66.

[0062] In this embodiment, the printing and dyeing wastewater is used to impact the impacted plate 63 to deflect it, and the position of the wedge block 68 is adjusted by using the deflection angle of the impacted plate 63. The inclined surface of the wedge block 68 squeezes the pressing device of the press-type flow rate valve 62, thereby adjusting the flow rate of the printing and dyeing wastewater in the press-type flow rate valve 62 to reduce the impact force of the printing and dyeing wastewater on the filter cartridge 44, thereby preventing the filter cartridge 44 from being deformed and affecting its filtering effect.

[0063] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
