[0002] Flocculation sedimentation is an important operation unit in the production process, and is responsible for the main task of treating suspended particles in water sources. After the existing sedimentation tank has been working for a long time, the sludge is easy to stay on the mud channel, which makes the sludge discharge bucket easy to be blocked. At this time, it is necessary to drain the sedimentation water in the tank and flush the sludge in the sludge discharge bucket, which seriously affects the flocculation sedimentation efficiency of the sedimentation tank. Therefore, a flocculation sedimentation device for a sedimentation tank is proposed. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a flocculation sedimentation device for a sedimentation tank, which solves the technical problem of poor sedimentation efficiency of the sedimentation tank caused by flushing a sludge discharge pipe when emptying the sedimentation tank.

[0008] The inclination angle of the oblique fixing plate is consistent with the inclination angle of the inner side wall of the annular drainage sleeve;

[0009] A water inlet pipe is installed on the side wall of the top plate, a mud discharge hopper is fixedly connected to the bottom of the inclined plate, and a discharge hopper for taking out sediment is provided at the bottom of the mud discharge hopper.

[0010] By means of the above technical solution, the utility model provides a flocculation sedimentation device for a sedimentation tank, which has at least the following beneficial effects:

[0011] 1. The utility model realizes directional drainage of suspended matter in the sludge in the sedimentation tank through the sludge guide mechanism. At the same time, through the coordinated arrangement between the inclined plate and the arc-shaped guide plate, the sediment in the sedimentation tank is gathered in an oblique direction, which effectively improves the sludge discharge efficiency of the sedimentation tank.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] Please refer to Figure 1-Figure 3A flocculation sedimentation device for a sedimentation tank, the sedimentation device comprises an inclined plate 1 arranged on four sides of the sedimentation tank, a top plate 2 is fixedly connected to the top of the inclined plate 1, a motor 3 is installed on the top of the top plate 2, and a sludge guide mechanism 7 is arranged inside the inclined plate 1;

[0022] The sludge guide mechanism 7 includes two lifting cylinders 70 symmetrically fixedly connected to the bottom wall of the top plate 2. The adjacent inclined plates 1 are arranged equidistantly at 90 degrees. The bottom connection of the adjacent inclined plates 1 is provided with an arc guide plate 71. The arc guide plate 71 is set as a convex arc surface. The suspended matter and the sludge converge obliquely along the inclined plate 1 and the upper edge of the arc guide plate 71, which accelerates the sedimentation speed of the suspended matter and effectively improves the flocculation sedimentation efficiency of the sedimentation tank.

[0023] The output end of the motor 3 is fixedly connected to a rotating shaft 72, and a scraping assembly is provided at the bottom of the rotating shaft 72. A baffle plate 73 is slidably sleeved on the outer side of the rotating shaft 72. The output end of the lifting cylinder 70 is fixedly installed on the top wall of the baffle plate 73. When it is necessary to discharge mud from the sedimentation tank, the lifting cylinder 70 is turned on to move the baffle plate 73 downward. Since the inclined plate 1 is arranged as an inclined surface with a width at the top and a narrowness at the bottom, when the baffle plate 73 moves downward to the bottom of the inclined plate 1, the baffle plate 73 realizes the blockage between the inclined plate 1 and the annular drainage sleeve 78, which is convenient for the subsequent scraping assembly to scrape the sludge on the inner wall of the annular drainage sleeve 78.

[0024] Embodiment 2

[0025] Please refer to Figure 3-Figure 4 This embodiment is basically the same as the first embodiment. This embodiment is made on the basis of the first embodiment and has the same beneficial effects as the first embodiment. The same parts can be referred to each other and will not be described in detail here.

[0026] When the sedimentation tank starts to discharge mud, the motor 3 is turned on to drive the rotating shaft 72 to rotate, so as to scrape the accumulated mud. The inclined plate 1 is located above the baffle plate 73, and an annular drainage sleeve 78 is provided below the baffle plate 73 and located on the inner wall of the tank body. The annular drainage sleeve 78 is set in an inverted cone shape. After the mud enters the annular drainage sleeve 78, it is affected by the inclined inclined plate 1 and the oblique drainage of the arc-shaped guide plate 71, and continues to slide up and down along the annular drainage sleeve 78 and falls into the interior of the mud bucket 5. The scraping assembly includes a fixed sleeve 74 fixedly installed on the outside of the rotating shaft 72. The fixed sleeve 74 is located below the baffle plate 73, and a plurality of support rods 75 are equidistantly fixedly installed on the side wall of the fixed sleeve 74. The ends of the support rods 75 are fixedly connected to the oblique fixed plates 76. The outer sides of the oblique fixed plates 76 are provided with cleaning brushes 77. After the sedimentation tank has been working for a long time, the suspended matter adheres to the annular drainage sleeve 78. When cleaning, the motor 3 is turned on to drive the oblique fixed plate 76 to rotate synchronously, so that the cleaning brush 77 scrapes the inner wall of the annular drainage sleeve 78, effectively scrapes off the accumulated sludge, and the scraped sludge falls into the sludge discharge bucket 5 and finally falls into the inside of the discharge hopper 6.

[0027] As a preferred technical solution of this embodiment, the inclination angle of the oblique fixed plate 76 is consistent with the inclination angle of the inner wall of the annular drainage sleeve 78, ensuring that the cleaning brush 77 fits against the inner wall of the annular drainage sleeve 78 when the inclined oblique fixed plate 76 rotates, thereby effectively scraping off the sludge attached to the inner wall.

[0028] As a preferred technical solution of this embodiment, a water inlet pipe 4 is installed on the side wall of the top plate 2, a sludge hopper 5 is fixedly connected to the bottom of the inclined plate 1, and a discharge hopper 6 for removing sediment is provided at the bottom of the sludge hopper 5. The sewage enters the interior of the tank along the water inlet pipe 4, passes through the sludge diversion mechanism 7 and the interior of the sludge hopper 5, and finally falls into the interior of the discharge hopper 6.

[0029] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
