[0011] The technical solution of the present invention achieves the following beneficial technical effects:

[0012] 1. This invention, by setting multiple filter support plates arranged side by side, and cooperating with multiple sets of first and second intercepting rods arranged in a cross pattern, forms an interlaced three-dimensional mesh structure in the gap space of the filter support plates. Compared with the traditional planar filter structure, it has the characteristics of being less prone to clogging and having a better fiber interception effect.

[0013] 2. This invention, by setting up a first driving component and a second driving component, enables multiple filter support plates to form a funnel shape with openings facing the water flow within the sewage tank when the interception resistance increases after a certain period of use. This changes the filter plates from being parallel to the water flow direction to having a certain angle with the water flow direction, thereby using the filter plates for auxiliary filtration and avoiding clogging. The structure, which is larger at the front and smaller at the back, can retain fibers within the treatment equipment after intercepting a large amount of fibers, preventing the fibers from being washed away by wastewater. Furthermore, after forming the funnel shape, the positions of the interception rods at the front end change, obtaining new interception space, allowing water to pass through while intercepting fibers, thus increasing the sewage treatment time.

[0014] 3. In this invention, by setting intersecting interception rods oriented towards the water flow direction, when a large amount of fiber is intercepted on the interception rods and subjected to greater pressure, the two interception rods move closer to each other, forming a new interception space in the intersection area, which effectively improves the wastewater treatment time.

[0015] 4. This invention, by setting up a lifting assembly, can gradually tighten the filter support plate when a certain amount of fiber is trapped inside the processing equipment and the resistance is constant, squeezing out the water in the trapped fiber and automatically lifting the processing equipment out of the sewage tank to achieve drainage, which facilitates the subsequent recycling of the fiber; the filter support plate can be manually separated later, and each filter support plate has only one trapping rod facing the same direction on one side, which can be separated from the trapping rod with a simple combing operation, which facilitates the recycling of the fiber.

Detailed Implementation

[0027] This embodiment describes a wastewater treatment device containing fiber. Please refer to [link / reference]. Figure 1-2The system includes a support frame 2 that slides within a wastewater tank 1. Two or more filter support plates 3 are mounted on the support frame 2, arranged along the direction of water flow within the wastewater tank 1. Racks 4 are mounted along the length of the top edges of both sides of the wastewater tank 1. A first drive assembly 5 is mounted at the top center of the support frame 2, and a second drive assembly 6 is mounted at the rear top of the support frame 2. The power input components of the first and second drive assemblies 5 and 6 are respectively connected to the racks 4. The first drive assembly 5 drives the middle portions of the two or more filter support plates 3 to move closer together, and the second drive assembly 6 drives the rear portions of the two or more filter support plates 3 to move closer together. The speed at which the rear sections approach each other is greater than the speed at which the middle sections of the filter support plates 3 are driven to approach each other by the first drive assembly 5; a first intercepting rod 10 and a second intercepting rod 11 are respectively installed on the opposite sidewalls of two adjacent filter support plates 3, and the first intercepting rod 10 and the second intercepting rod 11 are both facing the direction of water flow and are arranged to cross each other; an opening is opened on the sidewall of the filter support plate 3, and a filter plate 7 is installed in the opening. By setting multiple filter support plates 3 arranged side by side, and cooperating with multiple sets of first intercepting rods 10 and second intercepting rods 11 arranged to cross each other, an interlaced three-dimensional mesh structure is formed in the gap space of the filter support plate 3. Compared with the traditional planar filter mesh structure, it has the characteristics of being less prone to clogging and having a better fiber interception effect.

[0028] like Figure 4 As shown, two or more pairs of first intercepting rods 10 and second intercepting rods 11 are installed on the opposite sidewalls of two adjacent filter support plates 3, and the first intercepting rods 10 and second intercepting rods 11 that are vertically adjacent are staggered. The density of the first intercepting rods 10 and second intercepting rods 11 on the filter support plate 3 gradually increases from front to back. The first intercepting rods 10 and second intercepting rods 11 can swing along the water flow direction. The ends of the first intercepting rods 10 and second intercepting rods 11 connected to the filter support plate 3 are hinged, so that the intercepting rods can swing along the water flow direction. A rubber strip is fixed to the end of the intercepting rod, and the other end of the rubber strip is fixed to the filter support plate 3, so that the intercepting rods will not swing randomly and have a certain stabilizing effect. By setting the intercepting rods that are intersecting and facing the water flow direction, when the intercepting rods trap more fibers and are subjected to greater pressure, the two intercepting rods move closer to each other and form a new interception space in the intersection area, which effectively improves the sewage treatment time.

[0029] like Figure 2As shown, the first drive assembly 5 includes a first support base 501, a first gear 502, and a first bidirectional lead screw 503. The first support base 501 is fixedly installed on both sides of the top of the support frame 2. The smooth rods at both ends of the first bidirectional lead screw 503 pass through the first support base 501 and are rotatably connected to the first support base 501. The first gear 502 is fixedly installed on both ends of the first bidirectional lead screw 503 and meshes with the rack 4. The first pressure plate 504 is threadedly connected to both ends of the first bidirectional lead screw 503. The two first pressure plates 504 are respectively attached to the side walls of the two outermost filter support plates 3. The first pressure plate 504 is fitted with a first limiting sleeve, which is fixedly connected to the side wall of the filter support plate 3. A rotating shaft 506 is fixedly installed on the top of the filter support plate 3. A connecting block 505 is rotatably installed on the rotating shaft 506. A support spring 507 is fixedly installed between two adjacent connecting blocks 505.

[0030] like Figure 2 As shown, the second drive assembly 6 includes a second support base 601, a second bidirectional lead screw 602, a second gear 604, and an equidistant control assembly 605. The second support base 601 is fixedly installed on both sides of the top of the support frame 2. The two ends of the second bidirectional lead screw 602 pass through the two second support bases 601 respectively and are rotatably connected to them. The second gear 604 is fixedly installed on both ends of the second bidirectional lead screw 602, and the second gear 604 meshes with the rack 4. The two ends of the second bidirectional lead screw 602 are threadedly connected to second pressure plates 603. The two second pressure plates 603 are respectively attached to the side walls of the two outermost filter support plates 3. Second limiting sleeves are fitted onto the second pressure plates 603, and the second limiting sleeves are fixedly connected to the side walls of the filter support plates 3. The control component 605 is connected to the top of two or more filter support plates 3 respectively. By setting the first drive component 5 and the second drive component 6, after a certain period of use, when the interception resistance increases, the multiple filter support plates 3 are driven by the water flow to form a funnel shape with the opening facing the water flow in the sewage tank 1. The filter plate 7 is changed from being parallel to the water flow direction to having a certain angle with the water flow direction, so as to use the filter plate 7 for auxiliary filtration and avoid clogging. The structure of being larger in the front and smaller in the back can retain the fibers in the treatment equipment after intercepting more fibers, preventing the fibers from being washed away by the wastewater. Secondly, after the funnel shape is formed, the position of the interception rods at the front end changes, obtaining a new interception space, allowing water to pass through and intercepting fibers, increasing the sewage treatment time.

[0031] like Figure 3As shown, the equidistant control assembly 605 includes two or more interconnected hinge members. Each hinge member includes a first hinge rod 606 and a second hinge rod 607. The middle parts of the first hinge rod 606 and the second hinge rod 607 are hinged by a pin 608. The pin 608 is rotatably connected to the top of the filter support plate 3. The first hinge rod 606 and the second hinge rod 607 of two adjacent hinge members are hinged by the pin 608.

[0032] like Figure 5 As shown, a front-end sealing assembly 8 is installed between the front ends of two adjacent filter support plates 3. The front-end sealing assembly 8 includes a push rod 801, a sliding block 803, and a sealing plate 804. One end of the push rod 801 is hinged to one filter support plate 3. A groove 802 is provided on the side wall of the other filter support plate 3. The sliding block 803 is slidably installed in the groove 802. The other end of the push rod 801 is inserted into the groove 802 and abuts against the rear end of the sliding block 803. A drive wheel is rotatably installed in the groove 802. The circumferential side wall of the drive wheel is tightly fitted to the side wall of the sliding block 803. One side of the sealing plate 804 is fixedly connected to the drive wheel.

[0033] like Figure 9-10As shown, a lifting assembly 9 is installed on the sewage tank 1 behind the filter support plate 3. The lifting assembly 9 includes a first support rod 901, a second support rod 902, a connecting rod 903, and a lifting rod 904. One end of the first support rod 901 and the second support rod 902 are rotatably connected to the side wall of the sewage tank 1. The other ends of the first support rod 901 and the second support rod 902 are respectively hinged to both ends of the connecting rod 903. A telescopic support rod 906, which is a pneumatic spring, is hinged to the side wall of the second support rod 902. The telescopic rod and telescopic support rod 906 are hinged at one end to the side wall of the sewage tank 1. A fixing hook 905 is hinged to the side wall of the sewage tank 1. The hook of the fixing hook 905 is fastened to the top wall of the connecting rod 903. A fixing block 907 is fixedly installed on the side wall of the connecting rod 903. A hanging rod 904 is fixedly installed at the end of the fixing block 907 facing the support frame 2. A lifting ring 910 is installed on the top of the support frame 2. An installation groove is opened in the fixing block 907, and a trigger block 908 is installed in the installation groove. A trigger block 908 is installed in one side of the fixing block 907. The push rod 909 and the trigger block 908 have an inclined surface on the side facing the push rod 909. One end of the push rod 909 abuts against the inclined surface, and the other end abuts against the side wall of the fixed hook 905. An elastic pull strap 12 is fixedly connected to the support frame 2, and a fixed column is fixedly installed on the sewage tank 1. The other end of the elastic pull strap 12 is sleeved on the fixed column. Slider blocks 201 are fixedly installed on both sides of the support frame 2, and a sliding support groove 101 is provided on the top of the sewage tank 1. The slider 201 slides in the sliding support groove 101. On 01, by setting up the lifting component 9, when a certain amount of fiber is trapped in the processing equipment and the resistance is constant, the filter support plate 3 is gradually tightened to squeeze out the water in the trapped fiber and automatically lift the processing equipment out of the sewage tank 1 to achieve drainage, which is convenient for subsequent fiber recycling. The filter support plate 3 can be manually separated later. Each filter support plate 3 has only one trapping rod 11 facing the same direction on one side. Only a simple combing operation is needed to separate the recycled fiber from the trapping rod 11, which is convenient for fiber recycling.

[0034] Work process: When treating fiber-containing wastewater, the wastewater is introduced into the sewage tank 1. In the initial state, there is a certain initial friction between the slider 201 and the sliding support groove 101 to ensure that the filter support plate 3 will not be driven by the water flow when no fibers are trapped.

[0035] Fibers in the wastewater enter the gaps between the filter support plates 3 along with the water flow and are trapped by the three-dimensional structure formed by the intersection of the first intercepting rod 10 and the second intercepting rod 11, thus achieving wastewater treatment; for example Figure 8As shown, the dashed line represents the initial crossing state of the first intercepting rod 10 and the second intercepting rod 11 without intercepting fibers. The distance from their free ends to the initial crossing point is c. After continuous interception, the fibers are intercepted and attached to segment c. The intercepting rods experience increasing resistance and are pushed by the water. The solid line represents the new crossing state of the first intercepting rod 10 and the second intercepting rod 11 after being pushed by the water flow. The distance between the initial crossing point and the new crossing point is d. Since there are no fibers attached to segment d, wastewater can pass through and continue to intercept the fibers.

[0036] As the wastewater is continuously trapped, the gaps between the filter plates and the support frame decrease, increasing the resistance and causing the filter support plate 3 and the support frame 2 to move with the water flow. This, in turn, pulls the elastic strap 12, causing it to move backward continuously. Figure 2 The first gear 502 and the second gear 604 rotate in cooperation with the rack 4, thereby driving the first bidirectional lead screw 503 and the second bidirectional lead screw 602 to rotate. When the second bidirectional lead screw 602 rotates, it pushes the rear end of the filter support plate 3 inward synchronously through the two second pressure plates 603. Under the action of the equidistant control component 605, the equidistant distance at the rear end of each filter support plate 3 decreases and narrows. After the filter support plate 3 is tilted, the filter plate 7 intersects with the water flow direction, which can play an auxiliary filtration role.

[0037] The first bidirectional lead screw 503 synchronously pushes the outermost filter support plate 3 inward through the two first pressure plates 504. Under the action of the support spring 507, a certain gap is maintained between each filter support plate 3, and each filter support plate 3 can swing to a certain extent, realizing a funnel-shaped structure with a large inlet and a small outlet; Figure 7 As shown, the dashed line represents the intersection state of the first intercepting rod 10 and the second intercepting rod 11 at their initial positions without movement of the filter support plates 3 on both sides. The distance between the position where the intercepting rod connects to the filter support plate 3 and the initial intersection point is 'a'. Fibers are continuously intercepted onto the intercepting rods. When the filter support plates 3 on both sides move, the black line represents the new intersection state after the filter support plates 3 are driven by the first driving component 5 and the second driving component 6, which in turn drive the intercepting rods to move. The distance between the initial intersection point and the new intersection point is 'b'. The first intercepting rod 10 and the second intercepting rod 11 pull against each other, squeezing the fibers in the intersection area to a certain extent. The extracted new segment b has fibers pushed on it, meaning there are no or few attached fibers, allowing for continued interception processing.

[0038] like Figure 1As shown, since the first gear 502 is located in front of the second gear 604, meaning the first gear 502 rotates more times than the second gear 604, as filtration continues, the number of fibers intercepted in the gap of the filter support plate 3 increases, resulting in greater resistance. These fibers are continuously pushed backward by the water flow. The second gear 604 gradually tightens the rear part of the filter support plate 3 to prevent the intercepted fibers from being washed away by the water. Subsequently, the second gear 604 disengages from the rack 4, and the first gear 502 continues to rotate and continuously presses against the filter support plate 3, squeezing out the water from the fibers. During this squeezing process, as... Figure 5 As shown, as the two filter support plates 3 gradually approach each other, the push rod 801 is squeezed and slides in the groove 802, pushing the sliding block 803. The sliding block 803 drives the drive wheel to rotate, causing the sealing plate 804 to close, thereby preventing the water squeezed out of the fiber from being carried out in the opposite direction. With continuous rotation, the sealing plate 804 eventually adheres to the filter support plate 3 in the opposite direction.

[0039] like Figure 1 , Figure 9 As shown, the support frame 2 moves backward, causing the lifting ring 910 to move, so that the lifting rod 904 inserts into the lifting ring 910, as... Figure 10 As shown, the lifting ring 910 then presses the trigger block 908, and uses the inclined plane to push the top rod 909, causing the fixing hook 905 to disengage. Under the action of the telescopic support rod 906, the first support rod 901, the second support rod 902 and the connecting rod 903 are unfolded, lifting the support frame 2 and causing the filter support plate 3 to be removed from the water surface for drainage.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
