Description

Technical Field

[0001] The utility model relates to the technical field of chemical production equipment, in particular to a clarification reaction kettle for strontium carbonate production and desulfurization. Background Art

[0002] Strontium and strontium salts are widely used in electronics, chemicals, metallurgy, military industry, functional materials and fireworks manufacturing. Celestite is the main strontium ore raw material for the production of various strontium salt compounds. The production process of strontium salts produces a large amount of waste slag and waste gas. The main component of waste gas is SO2. In order to avoid direct emission of SO2 gas and cause air pollution, desulfurization towers are currently commonly used to desulfurize the waste gas. When the desulfurization tower is working, it is necessary to spray alkaline liquid to fully react with the waste gas passing through the desulfurization tower, thereby removing SO2 from the waste gas. Since industrial alkaline liquids are usually prone to precipitating precipitates, the alkaline liquid needs to be clarified when spraying it into the desulfurization tower. The existing industrial clarification process usually uses a clarification tank for static treatment, which not only has a long clarification cycle but also has poor clarification effect. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a clarification reactor for strontium carbonate production and desulfurization, aiming to provide a device that can quickly clarify alkaline liquids and improve the clarification effect.

The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figures 1 to 4 As shown, the utility model discloses a clarification reactor for strontium carbonate production and desulfurization, comprising a reactor body 100 and a mud scraping device 200, wherein the reactor body 100 is provided with an outer cylinder 110, an inner cylinder 120, an inlet pipe 130 and a water outlet pipe 140; the upper end of the inner cylinder 120 is fixedly connected to the top of the outer cylinder 110, and the lower end of the inner cylinder 120 is open; the inner cylinder 120 divides the outer cylinder 110 into a clarification chamber 101 and a sedimentation chamber 102; the inlet pipe 130 is provided at the upper end of the outer cylinder 110 and passes through the outer cylinder 110 and is connected to the sedimentation chamber 102, and the outlet pipe 140 is provided on the peripheral wall of the outer cylinder 110 and passes through the outer cylinder 110 and the inner cylinder 120 in sequence and is connected to the clarification chamber 101; the mud scraping device 200 is provided with a scraper 210, which can clean the sludge on the side wall of the outer cylinder 110.

[0032] Specifically, in this embodiment, the reactor body 100 is provided with an outer cylinder 110 and an inner cylinder 120. The lower end of the inner cylinder 120 is open, and the inner cylinder 120 divides the outer cylinder 110 into a clarification chamber 101 and a sedimentation chamber 102. The outer cylinder 110 serves as the outer shell of the entire reactor, providing not only physical support but also isolating the reactor from the external environment. The inner cylinder 120 is placed inside the outer cylinder 110, closely connected to the top of the outer cylinder 110 at the top, and open at the bottom to form an outlet. Located at the top of the outer cylinder 110, it directly connects to the sedimentation chamber 102 and is responsible for introducing the solution to be clarified. The outlet pipe 140 is sequentially interspersed between the outer cylinder 110 and the inner cylinder 120, ultimately connecting to the clarification chamber 101, ensuring the safe discharge of the purified liquid. This structural design effectively divides the clarification chamber 101 and the sedimentation chamber 102 into two relatively independent spaces, preventing fluid disturbance caused by the entry of external fluid from interfering with the operation of the clarification chamber 101. When the liquid to be clarified enters the sedimentation chamber 102 through the water inlet pipe 130, the heavier solid particles gradually sink to the bottom under the action of gravity. The inner cylinder 120 limits the flow path of the liquid to be clarified, so that the solid and liquid phases can be more fully separated in the clarification chamber 101. The clarified liquid is extracted from the outlet pipe 140, and the sedimentation material remains in the sedimentation chamber 102. Furthermore, in order to maintain the long-term and efficient operation of the reactor, the sludge accumulated on the side wall of the outer cylinder 110 must be regularly removed. To this end, a rotatable scraper 210 is configured through the scraping device 200. The scraper 210 can rotate and slide along the inner wall of the outer cylinder 110, effectively removing attachments on the inner wall of the outer cylinder 110, preventing blockage, and ensuring the internal cleanliness of the inner wall of the outer cylinder 110, thereby extending the service life.

[0033] In some embodiments of the present invention, an hourglass-shaped structure 103 is provided at the lower portion of the inner cylinder 120. The hourglass-shaped structure 103 is designed to guide the water flow upward, first converging and then slowly diffusing, thereby reducing the chance of the supernatant being disturbed and improving the purity of the liquid in the clarification chamber 101.

[0034] In some embodiments of the present invention, a funnel-shaped cylinder 111 is provided at the lower end of the outer cylinder 110. In this embodiment, the design of the funnel-shaped cylinder 111 increases the bottom slope angle of the outer cylinder 110, accelerates the sliding speed of solid particles, promotes rapid sedimentation, and effectively improves the separation efficiency. The inclined funnel wall makes it difficult for residual matter to be retained, reduces the possibility of bottom accumulation, facilitates regular cleaning, and makes maintenance simple and quick. It can prevent sediment from silting. Furthermore, the design of the funnel-shaped cylinder 111 forms a streamlined channel that helps the liquid transition smoothly, avoids turbulence, protects the liquid in the clarification cavity 101 from secondary contamination, and maintains a high-quality clarification effect.

[0035] In some embodiments of the present invention, the scraper device 200 includes a rotary drive 220, a coupling 230, and a control rod 240. The rotary drive 220 is fixedly connected to the upper end of the outer cylinder 110. The rotary drive 220 is connected to the upper end of the control rod 240 through the coupling 230. The lower end of the control rod 240 extends through the outer cylinder 110 and is removably connected to the scraper 210. In this embodiment, the rotary drive 220 is mounted on the upper end of the outer cylinder 110 and serves as a power source, providing stable rotational force for the scraping action. The coupling 230 ensures smooth and efficient power transmission, connecting the rotary drive 220 and the control rod 240 to ensure precise connection during energy conversion. The upper end of the control rod 240 is tightly connected to the coupling 230, while the lower end of the control rod 240 extends into the interior of the reactor. The scraping action is implemented and adjusted through a removable connection with the scraper 210. This structural design allows the start and stop of the rotary drive 220 to be controlled by a preset program or manual command, enabling it to be activated as needed without human intervention, saving time and labor. The length of the control rod 240 and the rotation radius of the scraper 210 ensure that the scraper 210 reaches every part of the outer cylinder 110, leaving no blind spots and thoroughly removing dirt.

[0036] In some embodiments of the present invention, the scraper 210 includes an extension portion 211 and a working portion 212. The extension portion 211 and the working portion 212 are fixedly connected, and the length direction of the working portion 212 is parallel to the generatrix of the funnel-shaped cylinder 111. In this embodiment, the extension portion 211 serves as a connecting portion and is tightly integrated with the control rod 240, thereby achieving power transmission while increasing the operating distance and ensuring that the scraper 210 reaches every corner of the reactor. The working portion 212 is fixedly connected to the extension portion 211, and its length direction is parallel to the generatrix of the funnel-shaped cylinder 111. This design maximizes the coverage of the cleaning area, follows the principles of fluid mechanics, and avoids leaving any residue.

[0037] In some embodiments of the present invention, a serrated structure 213 is provided on the working portion 212. In this embodiment, the serrated structure 213 provided on the working portion 212 can improve the cleaning efficiency of the scraper device 200 and its ability to remove stubborn stains. The serrated structure 213 is introduced on the working portion 212 to increase friction and cutting force, ensuring a deep cleaning effect.

[0038] In some embodiments of the present invention, the outer cylinder 110 is provided with a mud discharge pipe 150 at the lower end of the funnel-shaped cylinder 111. This pipe is equipped with a ball valve 151. In this embodiment, the mud discharge pipe 150 directly connects to the lowest point of the funnel-shaped cylinder 111, utilizing gravity to smoothly discharge sediment, ensuring unobstructed flow within the interior and reducing the risk of clogging. The ball valve 151 serves as a control element within the mud discharge pipe 150. By turning a handle, the internal passageway's state is altered, enabling immediate control of material discharge, ensuring both efficient cleaning and ease of operation.

[0039] In some embodiments of the present invention, an insulating cavity 104 is provided on the peripheral wall of the outer cylinder 110. In this embodiment, by providing the insulating cavity 104 on the peripheral wall of the outer cylinder 110, antifreeze liquid can be injected into the insulating cavity 104 when the ambient temperature is too low to prevent the liquid inside the outer cylinder 110 from freezing.

[0040] In some embodiments of the present invention, a first water pump 131 is provided on the water inlet pipe 130, and a second water pump 132 is provided on the water outlet pipe 140. In this embodiment, the first water pump 131 is responsible for directing water into the outer cylinder 110, providing sufficient pressure to ensure a stable and even flow of water into the sedimentation chamber 102. The second water pump 132 is responsible for output, delivering the treated clarified liquid to its destination, thus providing both transportation and pressure boosting.

[0041] In some embodiments of the present invention, a first solenoid valve is provided on the water inlet pipe 130, and a second solenoid valve is provided on the water outlet pipe 140. The flow rate and opening state of the water inlet pipe 130 and the water outlet pipe 140 are intelligently controlled by the first solenoid valve and the second solenoid valve.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
