Description

Technical Field

[0001] This utility model belongs to the field of polyaluminum impurity removal technology, and in particular relates to a desludge removal device for polyaluminum production. Background Technology

[0002] In the production of chemical slurries such as polyaluminum chloride, traditional solid-liquid separation processes have significant bottlenecks: static filtration is easily clogged by high-viscosity sludge, requiring frequent shutdowns for cleaning, which severely restricts continuous production efficiency; meanwhile, gravity sedimentation is difficult to completely separate ultrafine particles, and residual sludge can damage the product's crystal structure, affecting purity indicators. Existing technologies cannot simultaneously achieve efficient sludge removal, anti-clogging operation, and micron-level separation precision. Centrifuges have complex flow channels that are prone to material accumulation, while vibrating screening exacerbates crystal breakage. This leads to low recovery rates of high-value solutions, increased energy consumption, and accelerated equipment corrosion.

[0003] Therefore, we provide a desliming device for polyaluminum production to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a desludge removal device for polyaluminum oxide (PAO) production. The device involves placing a funnel-shaped plate above a support platform. A set of L-shaped separation tubes are fixedly connected in a circumferential array to the outer side of the connecting wall at the upper end of the funnel-shaped plate. The PAO solution requiring desludge removal is poured into the funnel-shaped plate. A drive motor rotates the funnel-shaped plate, causing the PAO solution in the funnel-shaped plate to move upwards along the inner wall of the funnel-shaped plate under centrifugal force to the filter ring on the inner wall of the connecting wall. The PAO solution passes through the filter ring under centrifugal force, leaving the sediment in the funnel-shaped plate, thus completing the desludge removal process. A liquid collection ring groove is set on the support platform, and one end of the separation tube extends into the liquid collection ring groove. The filtered PAO solution enters the liquid collection ring groove from the separation tube, completing the collection of the PAO solution.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a desliming device for polyaluminum production, including a funnel plate, a support platform, a liquid collection ring groove, and a set of separation tubes. A drive motor is installed below the support platform, and the output end of the drive motor passes through the platform surface. The funnel plate is a funnel structure that gradually expands outwards upwards. The lower closed end of the funnel plate is fixedly installed on the output end of the drive motor. The upper open end of the funnel plate extends upwards and is fixedly provided with a docking wall. A filter ring is sleeved inside the docking wall. The separation tubes are L-shaped tube structures. A set of separation tubes is circumferentially arrayed and fixedly connected to the outer wall of the docking wall at one horizontal end. The liquid collection ring groove is set at the upper end of the support platform, and one end of the separation tube extends into the liquid collection ring groove.

[0006] A further feature of this invention is that a set of ball bearing seats are fixedly arranged in a circumferential array on the surface of the support platform. A hemispherical groove is formed on the upper end face of the ball bearing seat, and a ball bearing is rolled in the hemispherical groove of the ball bearing seat. The lower closed end of the funnel plate is attached to the ball bearing.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0015] Please see Figure 1 and Figure 2This utility model is a desludge removal device for polyaluminum production, including a funnel plate 1, a support platform 2, a liquid collection ring trough 3, and a set of separation pipes 4. The funnel plate 1 is placed above the support platform 2, and a set of L-shaped separation pipes 4 are fixedly connected in a circumferential array to the outer side of the docking wall 101 at the upper end of the funnel plate 1. The polyaluminum solution to be desludged is poured into the funnel plate 1, and the funnel plate 1 is driven to rotate by the drive motor 201. Under the action of centrifugal force, the polyaluminum solution in the funnel plate 1 moves up along the inner wall of the funnel plate 1 to the filter ring 101a on the inner wall of the docking wall 101. Under the action of centrifugal force, the polyaluminum solution passes through the filter ring 101a, leaving the mud and sand in the funnel plate 1, thus completing the desludge removal of polyaluminum. By setting the liquid collection ring trough 3 on the support platform 2, one end of the separation pipe 4 extends into the liquid collection ring trough 3, and the filtered polyaluminum solution enters the liquid collection ring trough 3 from the separation pipe 4, thus completing the collection of polyaluminum solution.

[0016] Specifically, a drive motor 201 is installed below the support platform 2. The output end of the drive motor 201 passes through the platform surface of the support platform 2. The funnel disk 1 has a funnel structure that gradually expands outwards. The lower closed end of the funnel disk 1 is fixedly installed on the output end of the drive motor 201. The upper open end of the funnel disk 1 extends upward and is fixedly provided with a docking wall 101. A filter ring 101a is sleeved inside the docking wall 101. The separation tube 4 is an L-shaped tube structure. A set of separation tubes 4 is circumferentially arrayed and fixedly connected to the outer wall of the docking wall 101. The liquid collection ring groove 3 is set at the upper end of the support platform 2. One end of the separation tube 4 extends into the liquid collection ring groove 3.

[0017] Furthermore, a set of ball bearing seats 202 are fixedly arranged in a circumferential array on the platform surface of the support 2. A hemispherical groove is formed on the upper end surface of the ball bearing seat 202. A ball bearing 202a is rolled in the hemispherical groove of the ball bearing seat 202. The lower closed end of the funnel plate 1 is attached to the ball bearing 202a. The weight of the funnel plate 1 is borne by the ball bearing 202a and the ball bearing seat 202. When the funnel plate 1 rotates, the bottom of the funnel plate 1 rolls and rubs against the ball bearing 202a, reducing the friction of the funnel plate 1.

[0018] Furthermore, a ball sleeve 202b is fixedly fitted to the outer side of the ball seat 202, and the ball 202a passes through the ball sleeve 202b.

[0019] The operation process in this embodiment is as follows: The polyaluminum chloride solution requiring sludge removal is poured into the funnel pan 1. The drive motor 201 drives the funnel pan 1 to rotate, causing the polyaluminum chloride solution in the funnel pan 1 to move upward along the inner wall of the funnel pan 1 under the action of centrifugal force to the filter ring 101a on the inner wall of the docking wall 101. Under the action of centrifugal force, the polyaluminum chloride solution passes through the filter ring 101a, leaving the sludge in the funnel pan 1, thus completing the sludge removal of the polyaluminum chloride solution. The filtered polyaluminum chloride solution enters the liquid collection ring trough 3 from the separation pipe 4, thus completing the collection of the polyaluminum chloride solution. Example 2

[0020] Please see Figures 1 to 5 Based on Example 1, a ring brush assembly 102 is provided inside the funnel disk 1. The ring brush assembly 102 includes a shaft 102a and a set of ring brushes 102b. By attaching the ring brushes 102b to the inner wall of the filter ring 101a, when the funnel disk 1 rotates, the impurity mud particles in the polyaluminum solution are filtered by the filter ring 101a, and the ring brushes 102b brush away the impurity mud particles on the inner wall of the rotating filter ring 101a, thereby preventing the filter holes of the filter ring 101a from becoming clogged.

[0021] Specifically, the outer wall of the docking wall 101 is fixed with an outer ring hoop 101b, and an inner buckle 101b-1 is fixed on the inner wall of the upper end face of the outer ring hoop 101b, which presses against the upper end face of the docking wall 101.

[0022] Furthermore, the ring brush assembly 102 is attached to the inner wall of the filter ring 101a.

[0023] Furthermore, a support rod 203 is fixed on each side of the upper end face of the support platform 2, and a crossbeam 203a is fixed between the upper ends of the two support rods 203. The ring brush assembly 102 is set on the lower end face of the middle section of the crossbeam 203a.

[0024] Furthermore, the upper end of the shaft 102a is fixedly installed at the lower end of the middle section of the crossbeam 203a. A set of brush sleeves 102a-1 are fixedly arranged in a circumferential array on the lower side wall of the shaft 102a. Each ring brush 102b is horizontally slidably sleeved in each brush sleeve 102a-1. The end of the ring brush 102b away from the shaft 102a is attached to the inner wall of the filter ring 101a. A compression spring 102a-2 is sleeved inside the brush sleeve 102a-1. The two ends of the compression spring 102a-2 are fixedly connected to one side of the ring brush 102b and the inner top surface of the brush sleeve 102a-1, respectively. The compression spring 102a-2 squeezes the ring brush 102b, so that the ring brush 102b is tightly attached to the inner wall of the filter ring 101a, thereby enabling the ring brush 102b to fully brush the filter ring 101a.

[0025] The operation process in this embodiment is as follows: When the funnel disk 1 rotates, the impurities and mud particles in the polyaluminum solution are filtered by the filter ring 101a. The compression spring 102a-2 squeezes the ring brush 102b, so that the ring brush 102b fits tightly against the inner wall of the filter ring 101a, thereby enabling the ring brush 102b to fully brush the filter ring 101a and prevent the filter holes of the filter ring 101a from becoming clogged.
