[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation on the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0037] As Figures 1 to 3 shown, the embodiment of the present invention provides a slime water treatment device. The slime water treatment device includes a treatment tank 10, a first stirring assembly 20, a scraping part 30, and a second stirring assembly 40. Among them, the treatment tank 10 has a reaction chamber 101 and a precipitation chamber 102 that communicate with each other. The reaction chamber 101 is located above the precipitation chamber 102, and the cross-sectional area of the reaction chamber 101 is larger than the cross-sectional area of the precipitation chamber 102. The treatment tank 10 also has a material inlet 103, a waste liquid outlet 104, and a sediment outlet 105. The material inlet 103 and the waste liquid outlet 104 are respectively communicated with the reaction chamber 101, and the sediment outlet 105 is communicated with the precipitation chamber 102. The first stirring assembly 20 is arranged in the reaction chamber 101, and the first stirring assembly 20 is used for stirring the materials in the reaction chamber 101. The scraping part 30 is movably arranged in the reaction chamber 101, and the scraping part 30 abuts against the side wall of the reaction chamber 101. The second stirring assembly 40 is arranged in the precipitation chamber 102, and the second stirring assembly 40 is used for stirring the materials in the precipitation chamber 102. During the reaction process, the waste liquid outlet 104 is in a blocked state. And in the embodiment of this solution, it also includes a first blocking cover, and the first blocking cover is used for blocking the sediment outlet 105. During the precipitation process, the blocking cover blocks the sediment outlet 105.

[0038] Applying the technical solution of the present utility model, a reaction chamber 101 and a precipitation chamber 102 that communicate with each other in the height direction are formed inside the treatment tank 10. The first stirring assembly 20 is arranged in the reaction chamber 101, the second stirring assembly 40 is arranged in the precipitation chamber 102, and the scraping part 30 is movably arranged in the reaction chamber 101. With such an arrangement, the situation where particulate matter adheres to the side wall of the reaction chamber 101 can be reduced, and the situation where the sediment clogs the sediment outlet 105 can also be reduced. Specifically, the first stirring assembly 20 fully mixes the slime and the flocculant in the reaction chamber 101, and the scraping part 30 scrapes the particles adhering to the side wall of the reaction chamber 101; under the action of gravity, the solid particulate matter falls into the precipitation chamber 102, and the second stirring assembly 40 stirs the particulate matter in the precipitation chamber 102, reducing the possibility of the solid particulate matter clogging the sediment outlet 105 and improving the smoothness of discharging the solid particulate matter. Compared with the traditional technical solution, in this solution, the scraping part 30 can timely scrape the particles adhering to the side wall of the reaction chamber 101. After the solid particulate matter falls into the precipitation chamber 102, under the action of the second stirring assembly 40, the solid particulate matter is in a disturbed state, reducing the possibility of the solid particulate matter clogging the sediment outlet 105.

[0039] Furthermore, the slime water treatment device further includes a transmission assembly 50. The transmission assembly 50 is arranged between the first stirring assembly 20 and the second stirring assembly 40. The first stirring assembly 20 and the second stirring assembly 40 are connected through the transmission assembly 50, and the first stirring assembly 20 is drivingly connected to the second stirring assembly 40 through the transmission assembly 50 to enable the second stirring assembly 40 to perform the stirring operation. The setting of the transmission assembly 50 realizes the power transmission and coordinated work between the first stirring assembly 20 and the second stirring assembly 40, and improves the efficiency of the slime water treatment device.

[0040] In the embodiment of this solution, the first stirring assembly 20 includes a stirring shaft 21 and a first stirring part 22. Among them, the stirring shaft 21 is rotatably arranged in the reaction chamber 101, and the extending direction of the stirring shaft 21 is the same as the direction from the reaction chamber 101 to the precipitation chamber 102. The first stirring part 22 is arranged on the stirring shaft 21. The transmission assembly 50 is arranged between the stirring shaft 21 and the second stirring assembly 40, that is, during the rotation of the stirring shaft 21, the second stirring assembly 40 is driven to perform the stirring operation through the transmission assembly 50.

[0041] In an embodiment of this solution, the transmission assembly 50 includes a screw rod 51, a nut 52, and a transmission rod 53. Among them, the screw rod 51 is fixedly arranged in the precipitation chamber 102, and the extending direction of the screw rod 51 is the same as that of the stirring shaft 21. The nut 52 is sleeved on the screw rod 51 and is threadedly connected to the screw rod 51, and the second stirring assembly 40 is fixedly arranged on the nut 52. The transmission rod 53 is fixedly arranged on the stirring shaft 21 and is located on the side of the screw rod 51. The length direction of the transmission rod 53 is the same as that of the screw rod 51, and the second stirring assembly 40 is movably arranged on the transmission rod 53 along the length direction of the transmission rod 53. When performing the stirring operation, the rotation of the stirring shaft 21 drives the transmission rod 53 to rotate. Since the second stirring assembly 40 is movably arranged on the transmission rod 53 along the length direction of the transmission rod 53, under the action of the screw rod 51 and the nut 52, the rotation of the transmission rod 53 drives the second stirring assembly 40 to move along the length direction of the screw rod 51 during the rotation, realizing the stirring effect on the precipitation particles. Through the coordinated work of the screw rod 51, the nut 52, and the transmission rod 53, this solution realizes efficient, stable, and flexible stirring operations. This design not only improves the stability of the transmission and the effect of the stirring operation, but also optimizes the structural layout, making the entire slime water treatment device more compact, efficient, and easy to maintain.

[0042] Specifically, a guiding hole 531 is arranged on the transmission rod 53. The guiding hole 531 extends along the length direction of the transmission rod 53. Along the direction from the screw rod 51 to the transmission rod 53, the guiding hole 531 penetrates through the transmission rod 53. The second stirring assembly 40 is movably inserted into the guiding hole 531 and is in guiding cooperation with the guiding hole 531. The guiding hole 531 provides stable guidance for the second stirring assembly 40, reducing the vibration or deviation that may occur during the stirring process, thereby improving the stability of the entire system.

[0043] In an embodiment of this solution, the second stirring assembly 40 includes a plurality of stirring blades and a plurality of transmission rods 53. The transmission rods 53 and the stirring blades are arranged in one-to-one correspondence. The plurality of second stirring blades are distributed at intervals along the circumferential direction of the nut 52, and the plurality of transmission rods 53 are distributed at intervals along the circumferential direction of the screw rod 51 on the outer periphery of the screw rod 51. With such an arrangement, the stirring effect can be further improved, and the possibility of solid particle precipitation can be further reduced.

[0044] Furthermore, the transmission assembly 50 further includes a bearing 54. The bearing 54 is sleeved on the outer periphery of the screw rod 51. The inner ring of the bearing 54 is fixedly connected to the screw rod 51, and the outer ring of the bearing 54 is fixedly connected to the transmission rod 53. The setting of the bearing 54 provides stable support for the transmission rod 53, ensuring the stability of the transmission rod 53 during the rotation process.

[0045] In an embodiment of this solution, the screw rod 51 is coaxially arranged with the stirring shaft 21, and the screw rod 51 is rotatably connected to the stirring shaft 21. The slime water treatment device further includes a connecting rod 60, which is arranged in the sedimentation chamber 102. The connecting rod 60 is located at one end of the nut 52 away from the stirring shaft 21. One end of the connecting rod 60 is fixedly connected to the screw rod 51, and the other end is fixedly connected to the side wall of the sedimentation chamber 102. The coaxial arrangement of the screw rod 51 and the stirring shaft 21 makes the space occupied by the entire transmission system smaller, making the entire slime water treatment device more compact. The arrangement of the connecting rod 60 provides an additional support point for the screw rod 51, enhancing the stability of the transmission assembly 50 and the second stirring assembly 40.

[0046] Further, the first stirring part 22 includes a stirring frame. One end of the stirring frame is arranged on the side wall of the stirring shaft 21, and the other end extends towards the side wall of the reaction chamber 101. The scraping part 30 includes a scraping rod, and the scraping rod is arranged at one end of the stirring frame away from the stirring shaft 21. The shape of the scraping rod is adapted to the contour of the side part of the reaction chamber 101. With such an arrangement, the rotation of the stirring frame drives the rotation of the scraping rod, and there is no need to additionally arrange a driving component to drive the scraping rod for scraping operation, further improving the compactness of the structure.

[0047] This solution does not specifically limit the number of stirring frames.

[0048] In an embodiment of this solution, there are multiple stirring frames, and the multiple stirring frames are spaced apart along the circumferential direction of the stirring shaft 21.

[0049] Specifically, each stirring frame includes two horizontal rods and multiple vertical rods.

The multiple vertical rods are located between the two horizontal rods, and the multiple vertical rods are spaced apart along the length direction of the horizontal rods. The two ends of the vertical rods are respectively connected to the two horizontal rods. With such an arrangement, the stirring effect of the first stirring part 22 can be improved.

[0052] In an embodiment of this solution, the slime water treatment device further includes a partition plate 80. The partition plate 80 is arranged in the treatment tank 10 and above the reaction chamber 101. The partition plate 80 and the treatment tank 10 cooperate to form an installation cavity 106, and the driving end of the driving assembly 70 is arranged in the installation cavity 106.
