[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0043] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] For example, see Figure 1-5The present invention provides a technical solution: an environmentally friendly pulp wastewater efficient recycling device, comprising a recovery tower 1, an addition pipe 3 and a water inlet pipe 2 are fixedly connected to the upper end of the recovery tower 1, a manhole 4 is provided at the upper end of the recovery tower 1, and the manhole 4 can be opened to clean the inside of the recovery tower 1, a partition 6 is fixedly connected to the inner wall of the recovery tower 1, a lifting block is fixedly connected to the top of the partition 6, a water outlet hole 1 8 and a water outlet hole 2 9 are provided on the surface of the recovery tower 1, and further comprising:

[0045] The filtering mechanism 5 includes a transverse plate 51, which is fixedly connected to the inner wall of the recovery tower 1 through a vertical rod 52 fixedly connected at the top center axis thereof. The bottom of the transverse plate 51 is connected to a filter frame 53 through four groups of connecting ropes 54. The middle of the filter frame 53 is hollow, and a placement groove 57 is provided on the inner wall of the filter frame 53. A leakage hole 58 is provided inside the groove wall of the placement groove 57. A filter plate 56 is placed inside the groove wall of the placement groove 57 and is rotatably connected to the placement groove 57 through a rotating shaft. The filter plate 56 is elliptical in shape, and its outer surface does not completely fit the groove wall of the placement groove 57. It can rotate slightly under the restriction of the rotating shaft. When the wastewater is recycled, the wastewater is passed into the recovery tower 1 from the water inlet pipe 2. After the inflowing wastewater falls on the surface of the filter frame 53, it flows along the filter frame 53 to the filter plate 56. After the large particles of debris in the wastewater are blocked by the filter plate 56, the wastewater falls through the filter plate 56.

[0046] The filter mechanism 5 also includes a limit block 55, which is fixedly connected to the inner wall of the recovery tower 1. The limit block 55 is located above the filter frame 53. An opening 551 is provided at the bend of the surface of the limit block 55. A spring 552 is fixedly connected to the inner wall of the opening 551. The spring 552 protrudes from the limit block 55 and is close to the outer surface of the filter frame 53. The limit block 55 is used to protect the recovery tower 1. After the sewage is passed into the water inlet pipe 2, the filter frame 53 is buffered by the spring 552. The filter frame 53 is provided with a spring 552 to provide a rebound force. When the wastewater impacts the filter frame 53, the filter frame 53 is shaken by the connecting rope 54. Because the water inlet pipe 2 is arranged to the right, the wastewater drives the filter frame 53 to deflect toward the limit block 55 after it falls. After the filter frame 53 deflects, it contacts and squeezes the spring 1 552. After the impact range of the wastewater on the filter frame 53 is reduced, the rebound force of the spring 1 552 assists in driving the filter frame 53 to return to its original position, so that the filter frame 53 can be continuously deflected.

[0047] When the filter frame 53 is deflected, the filter plate 56 rotates slightly around the rotating shaft under the restriction of the placement groove 57, and part of the wastewater flowing into the placement groove 57 can leak out through the leakage hole 1 58.

[0048] Example 2, based on Example 1, please continue to refer to Figure 6-7The present invention provides a technical solution: a sedimentation mechanism 7 is fixedly connected to the top of the partition 6, and the sedimentation mechanism 7 includes a connecting frame 1 71 and a connecting frame 2 72.

The connecting frame 1 71 and the connecting frame 2 72 are provided with a barrier assembly 74 inside. Two sets of fixing blocks 73 are fixedly connected to the outer surface of the connecting frame 1 71. The two fixing blocks 73 are both in contact with the inner wall of the recovery tower 1. The sides of the connecting frame 1 71 and the connecting frame 2 72 are respectively provided with a collecting tank 1 71 1 and collecting tank 722, the collecting tank 1 711 and collecting tank 2 722 are combined into an inclined annular groove for storing the collected large particles of impurities, and then discharged through the water outlet 1 8. After the wastewater falls from above, part of the wastewater carries the large particles of impurities that fall due to the deflection of the filter frame 53 and falls into the collecting tank 1 711 and collecting tank 2 722 opened outside the connecting frame 1 71 and the connecting frame 2 72. During subsequent cleaning, the wastewater carrying the large particles of impurities can be discharged through the water outlet 1 8 and then cleaned and recycled again.

[0049] A limiting frame 76 is fixedly connected to the central axis of the top of the connecting frame 2 72, and the limiting frame 76 is biased towards the inside of the connecting frame 2 72. A water outlet hole 3 75 is opened on the surface of the connecting frame 1 71, and the water outlet hole 3 75 is connected to the partition 6. One-way valves are arranged in the water outlet hole 1 8, the water outlet hole 2 9 and the water outlet hole 3 75 to control the water flow. The water outlet hole 3 75 is used to discharge the sewage after sedimentation. The sewage flows to the next area through the partition 6 after passing through the water outlet hole 3 75. When the sewage is located inside the connecting frame 1 71, chemical reagents such as flocculants are added to the recovery tower 1 through the adding pipe 3. After the water inlet pipe 2 stops injecting water into the recovery tower 1, the wastewater is mixed with the chemical reagents, so that the fine suspended matter and colloidal particles in the wastewater are condensed into larger particles. After standing, the large particles are precipitated, and the scum floats up. The water after internal treatment is sent to the bottom of the recovery tower 1 through the water outlet hole 3 75.

[0050] Example 3, based on Example 1 and Example 2, please continue to refer to Figure 8-9 , the present invention provides a technical solution: the barrier assembly 74 includes a pull rope 741, the top of the pull rope 741 passes through the filter plate 56 and is fixedly connected to the bottom of the horizontal plate 51, and the outer surface of the pull rope 741 is fixedly connected to a shaking component 742;

[0051] The barrier assembly 74 also includes a bracket 745, the shape of which is compatible with the shape of the inner wall of the connecting frame 1 71 and the connecting frame 2 72. The bottom of the bracket 745 is fixedly connected to a bottom plate 1 743, and the right side of the bottom plate 1 743 is rotatably connected to a bottom plate 2 744 through a bearing. The upper and lower ends of the bottom plate 1 743 and the bottom plate 2 744 are both located in the same horizontal plane. The bottom plate 1 743 and the bottom plate 2 744 are supported by a lifting block to collect large particles of impurities. The pull rope 741 passes through the bottom plate 1 743 and is fixedly connected to the bottom of the bottom plate 2 744. The outer surface of the bottom plate 1 743 is provided with a leakage hole 2 746. The bottom of the bottom plate 2 744 is fixedly connected to an arc plate 747. The arc plate 747 is used to limit the deflection angle of the bottom plate 2 744. When it is necessary to collect the large precipitated particles collected on the top of the bottom plate 1 743 and the bottom plate 2 744 , pull the bottom plate 743 upward by pulling rope 741, so that the bottom plate 743 moves upward along the connecting frame 71 until the bracket 745 contacts the limiting frame 76, and continue to pull the pulling rope 741. After the bracket 745 is blocked, the pulling rope 741 pulls the bottom plate 2 744 to deflect, and the large particles of sediment on the surface of the bottom plate 2 744 slide down its surface to the inside of the collecting tank 2 722 for collection. As the pulling rope 741 is continuously pulled up, the arc plate 747 is driven by the bottom plate 2 744 to deflect until it contacts the bottom of the bottom plate 1 743. Under the restriction of the arc plate 747, the bottom plate 1 743 is driven to deflect, and the large particles of sediment accumulated on the surface of the bottom plate 1 743 slide down to the inside of the collecting tank 2 722 for collection. After cleaning, loosen the pulling rope 741 to drive the bottom plate 1 743 and the bottom plate 2 744 to slide down to the top of the lifting block for reset.

[0052] Example 4, based on Example 1 and Example 2, please continue to refer to Figure 10-13The present invention provides a technical solution: the shaking component 742 includes a fixing sleeve 7421, the fixing sleeve 7421 is fixedly connected to the outer surface of the pull rope 741, the outer surface of the fixing sleeve 7421 is provided with a leakage groove 74211, the outer surface of the fixing sleeve 7421 is fixedly connected with a connecting plate 7422, the surface of the connecting plate 7422 is provided with a second opening 74221, the second opening 74221 and the leakage groove 74211 are communicated with each other, the top of the fixing sleeve 7421 is fixedly connected with a second spring 7425, the top of the second spring 7425 is fixedly connected with a connecting sleeve 7424, the upper end opening diameter of the connecting sleeve 7424 is larger than the lower end opening diameter, and is used to guide the water flow to the pull rope 741 The connection places where accumulation is easy to occur are flushed. When the filter frame 53 and the filter plate 56 are deflected, they can contact the pull rope 741, driving the pull rope 741 to shake, and when the pull rope 741 shakes, the fixed sleeve 7421 can be synchronously driven to shake, so that the shaking of the fixed sleeve 7421 can drive the connecting sleeve 7424 to shake, so that the water on the top of the connecting sleeve 7424 can flow to the fixed sleeve 7421 through the connecting sleeve 7424, and flush the top of the fixed sleeve 7421 to prevent the sediment from excessively adhering to the top of the fixed sleeve 7421. At the same time, when the fixed sleeve 7421 shakes, the connecting plate 7422 can be synchronously driven to shake, thereby increasing the mixing efficiency of the chemical agent and the wastewater.

[0053] The inner wall of the connecting plate 7422 is rotatably connected with the deflection plate 7423 through a rotating shaft, the top of the deflection plate 7423 is fixedly connected with a fixing frame 7426, one end of the fixing frame 7426 away from the deflection plate 7423 is fixedly connected to the surface of the connecting sleeve 7424, the fixing frame 7426 is fixedly connected with a connecting cover 7427 inside, a rectangular groove 7428 is provided on the surface of the fixing frame 7426, and a leakage hole 3 7429 is provided on the surface of the connecting cover 7427, and the leakage hole 3 7429 and the rectangular groove 7428 are located on the same vertical plane.
