Description

Technical Field

[0001] This utility model relates to the field of precipitation separation technology, specifically a high-purity arsenic precipitation separator. Background Technology

[0002] Arsenic is a metalloid element with three allotropes: gray arsenic (metallic arsenic), yellow arsenic, and black arsenic. It mainly forms alloys with copper, lead, and other metals. It is also used to manufacture arsenates, pharmaceuticals, and pesticides. High-purity arsenic can also be used in semiconductor and laser technology. In the preparation of arsenic, it often forms insoluble compounds with other metal ions. For example, arsenate ions can form insoluble salts with calcium and ferric ions. These impurities can be removed by precipitation, thus obtaining relatively pure arsenic compounds. In addition, precipitation separation can also help remove other impurities in the solution and improve the purity of the product.

[0003] Currently, the precipitation separators used for the preparation of high-purity arsenic require manual periodic opening of the valve to discharge the precipitate collected at the bottom of the precipitation separator, as they cannot be discharged automatically. This can easily lead to excessive accumulation of precipitate at the bottom of the precipitation separator, which overflows with the clear liquid and reduces the precipitation separation effect. Therefore, we propose a high-purity arsenic precipitation separator. Utility Model Content

[0004] The purpose of this invention is to provide a high-purity arsenic precipitation separator that can automatically discharge the precipitate collected at the bottom of the precipitation separator during the arsenic preparation process, ensuring the precipitation separation effect and improving the purity of arsenic preparation. This invention solves the problem that current high-purity arsenic preparation precipitation separators require manual periodic opening of valves to discharge the precipitate collected at the bottom of the precipitation separator, which cannot be automatically discharged. This can easily lead to excessive accumulation of precipitate at the bottom of the precipitation separator, which overflows with the clear liquid and reduces the precipitation separation effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-purity arsenic precipitation separator, comprising a precipitation separation cylinder, a vertical tube fixedly installed inside the precipitation separation cylinder by a fixing plate, a movable rod provided inside the vertical tube, a slider fixedly installed on the outer surface of the movable rod, a conical sealing block fixedly connected to one end of the movable rod below the vertical tube, a conical tube fixedly connected to the lower surface of the precipitation separation cylinder, a float fixedly installed on the outer surface of the movable rod below the slider, an annular liquid collection tank fixedly installed at the edge of the upper surface of the precipitation separation cylinder, a drain pipe fixedly connected to the outer surface of the annular liquid collection tank, and an inlet pipe fixedly installed on the outer surface of the precipitation separation cylinder, with the two ends of the inlet pipe located inside and outside the precipitation separation cylinder, respectively.

[0006] Preferably, four support plates are fixedly connected in a ring array at equal intervals near the edge of the lower surface of the sedimentation separation cylinder.

[0007] Preferably, one end of the inlet pipe located inside the sedimentation separation cylinder is fixedly connected to an annular pipe, and the annular pipe is fixedly sleeved on the outer surface of the vertical pipe, and an annular outlet is provided on the outer surface of the annular pipe.

[0008] Preferably, a sealing ring is fixedly installed on the outer surface of the movable rod at a position above the float, and the sealing ring is located inside the vertical tube.

[0009] Preferably, a helical spring is spirally wound on the outer surface of the movable rod above the slider, and a limit ring is fixedly inserted into the end of the vertical tube above the slider.

[0010] Preferably, the limiting ring and the vertical tube are fixedly connected by threads.

[0011] Preferably, a lifting cap is fixedly connected to one end of the movable rod located above the vertical tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a sedimentation separation cylinder, an annular collection tank, a drain outlet, a conical tube, a vertical pipe, a movable rod, a slider, a float, and a conical sealing block, achieves the effect of automatically discharging the precipitate collected at the bottom of the sedimentation separation cylinder during the arsenic preparation process, ensuring the sedimentation separation effect and improving the purity of arsenic preparation. The liquid produced during arsenic preparation enters the sedimentation separation cylinder through the inlet pipe. Solid impurities sink and are collected at the bottom of the sedimentation separation cylinder, while the clear liquid overflows from the upper part of the sedimentation separation cylinder and is collected in the annular collection tank, and then discharged through the drain pipe. When the amount of precipitate collected at the bottom of the sedimentation separation cylinder increases, the float will cause the conical sealing block to rise. When the conical sealing block rises, the precipitate is discharged from the conical tube. When the amount of precipitate decreases, the float descends, and the conical sealing block enters the conical tube to seal, thereby automatically discharging the precipitate at the bottom of the sedimentation separation cylinder 2.

[0014] 2. By setting up an annular pipe and an annular outlet, this utility model enables the liquid inside the inlet pipe to enter and be evenly distributed into the sedimentation separation cylinder along the annular pipe and annular outlet, reducing the fluctuations caused by the liquid entering the sedimentation separation cylinder to the original liquid inside the sedimentation separation cylinder, so as to facilitate sedimentation separation.

[0015] 3. This utility model utilizes a helical spring, which acts on the movable rod to improve sealing performance when the conical sealing block is inserted into the conical tube. Attached Figure Description

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figures 1-4 As shown, this utility model proposes a high-purity arsenic precipitation separator, including a precipitation separation cylinder 2. The precipitation separation cylinder 2 is cylindrical with an open top. A vertical pipe 4 is fixedly installed inside the precipitation separation cylinder 2 via a fixing plate 8. The vertical pipe 4 and the precipitation separation cylinder 2 are coaxial. A movable rod 12 is installed inside the vertical pipe 4, with its two ends located above and below the vertical pipe 4, respectively. A slider 16 is fixedly installed on the outer surface of the movable rod 12. A conical sealing block 13 is fixedly connected to the lower end of the movable rod 12 below the vertical pipe 4. A conical tube 7 is fixedly connected to the lower surface of the precipitation separation cylinder 2. A float 14 is fixedly installed on the outer surface of the movable rod 12 below the slider 16. A sealing ring 15 is fixedly installed on the outer surface of the 12 above the float 14, and the sealing ring 15 is located inside the vertical pipe 4. The sealing ring 15 can prevent the sediment from entering the area above the float 14. An annular liquid collection tank 5 is fixedly installed at the edge of the upper surface of the sedimentation separation cylinder 2. A drain pipe 6 is fixedly connected to the outer surface of the annular liquid collection tank 5. An inlet pipe 3 is fixedly installed on the outer surface of the sedimentation separation cylinder 2, and the two ends of the inlet pipe 3 are located inside and outside the sedimentation separation cylinder 2, respectively. The liquid generated during the arsenic preparation process enters the interior of the sedimentation separation cylinder 2 through the inlet pipe 3. Four support plates 1 are fixedly connected in an annular array at equal intervals near the edge of the lower surface of the sedimentation separation cylinder 2.

[0024] In use, the liquid produced during arsenic preparation enters the sedimentation separation cylinder 2 through the inlet pipe 3. Solid impurities settle and are collected at the bottom of the sedimentation separation cylinder 2, while the clear liquid overflows from the upper opening of the sedimentation separation cylinder 2 and is collected in the annular collection tank 5. It is then discharged through the drain pipe 6. When the amount of sediment collected at the bottom of the sedimentation separation cylinder 2 increases, the float 14 will cause the conical sealing block 13 to rise. When the conical sealing block 13 rises, the sediment is discharged from the conical tube 7. When the amount of sediment decreases, the float 14 descends, and the conical sealing block 13 enters the conical tube 7 to seal, thereby automatically discharging the sediment at the bottom of the sedimentation separation cylinder 2.

[0025] Example 2

[0026] like Figure 1 and Figure 3 As shown, the high-purity arsenic precipitation separator proposed in this utility model, compared with the first embodiment, further includes an inlet pipe 3 located inside the precipitation separation cylinder 2 with one end fixedly connected to an annular pipe 10, and the annular pipe 10 is fixedly sleeved on the outer surface of the vertical pipe 4, and an annular outlet 11 is provided on the outer surface of the annular pipe 10.

[0027] In this embodiment, the annular pipe 10 and the annular outlet 11 enable the liquid inside the inlet pipe 3 to enter and be evenly distributed into the sedimentation separation cylinder 2 along the annular pipe 10 and the annular outlet 11, thereby reducing the fluctuations caused by the liquid entering the sedimentation separation cylinder 2 to the original liquid inside the sedimentation separation cylinder 2, so as to facilitate sedimentation separation.

[0028] Example 3

[0029] like Figures 1-4 As shown, the high-purity arsenic precipitation separator proposed in this utility model, compared with Embodiment 1, further includes a spiral spring 17 spirally wound on the outer surface of the movable rod 12 above the slider 16, and a limiting ring 9 fixedly inserted into the end of the vertical tube 4 above the slider 16. The limiting ring 9 limits the spiral spring 17. The limiting ring 9 and the vertical tube 4 are fixedly connected by threads. A lifting cap 18 is fixedly connected to the end of the movable rod 12 above the vertical tube 4. The lifting cap 18 can pull the movable rod 12 to separate the conical sealing block 13 from the conical tube 7, so as to manually discharge the precipitate inside the precipitation separation cylinder 2.

[0030] In this embodiment, the elastic force of the helical spring 17 is applied to the movable rod 12 to improve the sealing performance when the conical sealing block 13 is inserted into the conical tube 7.

[0031] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
