Technical Field

[0001] This utility model relates to the field of calcium carbonate processing technology, specifically a calcium carbonate precipitation device. Background Technology

[0002] Calcium carbonate is an inorganic compound and a major component of limestone, marble, and other stone materials. It is an important building material with wide industrial applications. In the production process of calcium carbonate, in order to ensure and adapt to the dewatering requirements of centrifuges or plate and frame filter presses in the downstream process.

[0003] Generally, calcium carbonate suspension emulsions need to be concentrated by sedimentation. Currently, sedimentation tanks are mainly used for this process. However, when the supernatant is extracted after sedimentation, some of the precipitated calcium carbonate is extracted, resulting in waste of raw materials. Furthermore, the supernatant cannot be extracted according to the liquid level of the calcium carbonate slurry, leading to poor practicality.

[0004] Therefore, it is necessary to design a calcium carbonate precipitation device to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a calcium carbonate precipitation device to solve at least one technical problem existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A calcium carbonate precipitation apparatus, comprising: A sedimentation tank, wherein a bracket is provided at the edge of the opening of the sedimentation tank, an extension rod is fixed to the surface of the bracket, a sleeve rod is provided on the outside of the extension rod, and a horizontal plate is installed at the end of the sleeve rod away from the extension rod; A vertical rod is installed on a horizontal plate. A float plate is installed at one end of the vertical rod inside the sedimentation tank. An installation sleeve is provided on the lower surface of the float plate. A support foot is provided inside the installation sleeve. A suction pipe is connected to the end of the vertical rod away from the float plate.

[0007] Preferably, the bracket is an inverted "U"-shaped structure, and the bracket is symmetrically inserted into the opening edge of the sedimentation tank.

[0008] Preferably, one end of the extension rod is located inside the sleeve rod, and the extension rod and the sleeve rod constitute a telescopic structure.

[0009] Preferably, a locking bolt is installed at the end of the sleeve rod near the extension rod.

[0010] Preferably, the horizontal plate has a through hole, the vertical rod is located in the through hole, and the vertical rod is slidably connected to the horizontal plate through the through hole.

[0011] Preferably, the bottom of the float plate is provided with a suction port.

[0012] Preferably, the vertical rod has a hollow structure and is connected to the suction port.

[0013] Preferably, the mounting sleeves are distributed at equal angles at the bottom of the float, and the support legs are threadedly connected to the mounting sleeves.

[0014] Preferably, a limit ring is also installed on the edge of the vertical rod away from the float.

[0015] Compared with the prior art, the beneficial effects of this utility model are: After the calcium carbonate suspension emulsion is poured into the sedimentation tank for sedimentation, a horizontal plate is installed at the opening of the sedimentation tank via a sleeve rod, an extension rod, and a hanger. The length between the extension rod and the sleeve rod can be adjusted. The float plate at the lower end of the hollow vertical rod floats on the liquid surface under the buoyancy of the upper clear liquid. An external liquid pump can extract the upper clear liquid through a suction pipe, the hollow vertical rod, and a suction port. As the liquid level drops, the float plate will descend synchronously with the liquid level, continuously extracting the upper clear liquid. When the float plate gradually approaches the sediment, the mounting sleeve and support feet will stand on the sediment, creating a gap between the float plate and the sediment, thus preventing the sediment from being extracted and wasting raw materials.

[0025] Please see Figures 1-4 One embodiment provided by this utility model: A calcium carbonate precipitation apparatus, comprising: A sedimentation tank 1 has a hanging bracket 2 at the opening edge. An extension rod 3 is fixed to the surface of the hanging bracket 2. A sleeve rod 4 is provided on the outside of the extension rod 3. A horizontal plate 6 is installed at the end of the sleeve rod 4 away from the extension rod 3. The hanging bracket 2 has an inverted "U" shaped structure. The hanging bracket 2 is symmetrically inserted at the opening edge of the sedimentation tank 1. The horizontal plate 6 can be suspended at the opening of the sedimentation tank 1 through the sleeve rod 4, the extension rod 3 and the hanging bracket 2. One end of the extension rod 3 is located inside the sleeve rod 4. The extension rod 3 and the sleeve rod 4 form a telescopic structure, which is conducive to adapting to the opening size of the sedimentation tank 1 and making it easy to adjust. A vertical rod 7 is installed on a horizontal plate 6. A float plate 8 is installed at one end of the vertical rod 7 inside the sedimentation tank 1. An installation sleeve 10 is provided on the lower surface of the float plate 8. A support foot 11 is provided inside the installation sleeve 10. A suction pipe 13 is connected to the end of the vertical rod 7 away from the float plate 8.

[0026] In one embodiment, a locking bolt 5 is installed at one end of the sleeve rod 4 near the extension rod 3. After the length between the extension rod 3 and the sleeve rod 4 is adjusted, the two can be locked by tightening the locking bolt 5.

[0027] In one preferred embodiment, a through hole 14 is provided on the horizontal plate 6, and the vertical rod 7 is located in the through hole 14. The vertical rod 7 is slidably connected to the horizontal plate 6 through the through hole 14, which facilitates the vertical rod 7 to move up and down on the horizontal plate 6 through the through hole 14.

[0028] In one embodiment, the bottom of the float plate 8 is provided with a suction port 9, and the vertical rod 7 is a hollow structure. The vertical rod 7 and the suction port 9 are interconnected, which is conducive to the external suction pump to stably extract the upper clear liquid through the suction pipe 13, the hollow vertical rod 7 and the suction port 9 on the float plate 8.

[0029] In one preferred embodiment, the mounting sleeves 10 are distributed at equal angles at the bottom of the float plate 8, and the support legs 11 are threadedly connected to the mounting sleeves 10, so that the support legs 11 can be turned to adjust the distance between the float plate 8 and the sediment by screwing them into the mounting sleeves 10 through the threads.

[0030] In one preferred embodiment, a limiting ring 12 is also installed on the edge of the vertical rod 7 away from the float plate 8 to prevent the vertical rod 7 from completely sliding out of the perforation 14 under the action of gravity, which is conducive to maintaining the connection between the vertical rod 7 and the horizontal plate 6.

[0031] The working principle of this utility model is as follows: First, the calcium carbonate suspension emulsion is poured into the sedimentation tank 1 for sedimentation. After sedimentation, according to the opening size of the sedimentation tank 1, the extension rod 3 is pulled out and adjusted inside the sleeve rod 4 until the extension rod 3 and the sleeve rod 4 are adjusted to a suitable length. After the adjustment between the extension rod 3 and the sleeve rod 4 is completed, the locking bolt 5 is tightened. Then, the horizontal plate 6 is installed at the opening position of the sedimentation tank 1 through the sleeve rod 4, the extension rod 3, and the bracket 2. At this time, the float plate 8 at the lower end of the vertical rod 7 will float on the liquid surface under the buoyancy of the upper clear liquid. The liquid pump can extract the upper clear liquid through the suction pipe 13, the hollow vertical rod 7, and the suction port 9. When the liquid level drops, the float 8 will drop synchronously with the liquid level to continuously extract the upper clear liquid. When the float 8 gradually approaches the sediment, the mounting sleeve 10 and the support leg 11 will stand on the sediment, so that a gap is formed between the float 8 and the sediment, avoiding the extraction of sediment and waste of raw materials. At the same time, the support leg 11 can be turned on the mounting sleeve 10 for adjustment, so as to adjust the required distance between the float 8 and the sediment according to the specific situation.
