Description

Technical Field

[0001] This utility model relates to the field of sodium acetate production technology, and in particular to a stirring device for by-product sodium acetate. Background Technology

[0002] In the water treatment industry, sodium acetate trihydrate (also known as sodium acetate trihydrate) is commonly used as an effective carbon source in biological treatment systems for wastewater purification. Due to its simple molecular formula and structure, and ease of utilization by microorganisms, it is frequently used as a carbon source to provide nutrients for microbial growth and metabolism in wastewater biological treatment systems, improving the biodegradability of the wastewater's biological denitrification process. Sodium acetate trihydrate can be prepared from by-product sodium acetate (also known as sodium acetate mother liquor), which is a waste generated during factory production. This by-product contains not only various salts and organic matter but also many heavy metals, polluting the environment and wasting resources. Therefore, by-product sodium acetate is recycled and processed through impurity removal and centrifugation to produce sodium acetate trihydrate for use in the water treatment industry.

[0003] Chinese utility model patent CN 223027222 U discloses a device for dissolving by-product sodium acetate, belonging to the field of sodium acetate production technology. It includes a storage tank and a stirring assembly. The stirring assembly comprises a connecting shaft, a stirring paddle, a stirring element, a drive motor, and a lifting element. The connecting shaft is vertically suspended inside the storage tank. The stirring paddle is mounted on the connecting shaft and located inside the storage tank. The stirring element is mounted on the connecting shaft and located below the stirring paddle. The drive motor is located at one end of the connecting shaft. The lifting element is connected to the drive motor and drives the drive motor to move up and down vertically. By adding the stirring element and the lifting element, the stirring element first breaks down large crystalline by-product sodium acetate into smaller crystalline pieces, accelerating the dissolution of the crystalline by-product sodium acetate and increasing the dissolution rate. Simultaneously, it prevents the stirring paddle from colliding with the large crystalline by-product sodium acetate, thus preventing damage to the stirring paddle.

[0004] However, in the aforementioned patented sodium acetate by-product dissolution device, the stirring element is prone to breakage during long-term processing, affecting the stirring efficiency. Therefore, a solution is needed to improve this problem. Utility Model Content

[0005] The purpose of this invention is to provide a stirring device for by-product sodium acetate, so as to quickly replace and install damaged stirring components.

[0006] This utility model provides a stirring device for by-product sodium acetate, including a base and a storage assembly fixed on the base, a lifting assembly fixed on the base, and a stirring assembly fixed on the lifting assembly. The storage assembly includes a storage tank, a heating pipe fixed to the inner wall of the storage tank, and a liquid outlet valve communicating with the bottom of the storage tank. The lifting assembly includes a lifting rod and a lifting component that drives the lifting rod to move up and down. The stirring assembly includes a fixing feature fixed on the lifting rod, a positioning component fixedly engaged with the fixing feature, and a stirring component fixed to the bottom of the positioning component. The fixing feature includes an inner cavity and multiple fixing components slidably disposed in the inner cavity, and a return component disposed between two fixing components.

[0007] Using the above technical solution, the lifting component is driven to move vertically upward, which in turn drives the stirring component to move upward and to a position close to the top of the storage tank. The by-product sodium acetate solution or by-product sodium acetate crystals are placed in the storage tank, and an aqueous solution is added to mix them. The lifting rod is then driven to move vertically downward for a preset distance, first allowing the stirring component to enter the mixture. The motor is then started, driving the stirring component to rotate. The stirring component breaks up the by-product sodium acetate crystals present on the uppermost layer of the mixture. After a preset breaking time, the stirring paddle is also fully submerged in the mixture for mixing and stirring. After a preset breaking and stirring time, the lifting component is driven to move vertically downward for a preset distance, and the stirring component breaks up the by-product sodium acetate crystals present on the lowermost layer of the mixture. Simultaneously, the stirring paddle stirs the mixture until it is completely dissolved. After dissolution, the dissolved mixture can be discharged through the outlet valve.

[0008] Optionally, the heating tube is spirally fixed to the inner wall of the storage tank, and the outlet and inlet of the heating tube are respectively fixed to the bottom and top of the storage tank.

[0009] Using the above technical solution, the water inlet of the heating tube is located at the top of the storage tank. Hot water is introduced into the water inlet of the heating tube and enters the heating tube. The high temperature can accelerate the dissolution of the by-product sodium acetate with water. For example, when the water temperature is 25°C, approximately 36g of sodium acetate can be dissolved per kilogram of water, while when the water temperature is 100°C, approximately 100g of sodium acetate can be dissolved per kilogram of water. Therefore, heating the by-product sodium acetate mixed solution can effectively improve the dissolution rate. At the same time, attaching the heating tube to the inner wall of the storage tank can increase the heating rate of the by-product sodium acetate mixed solution.

[0010] Optionally, the positioning member and the fixing member have an angled position at their mating position, the fixing member is convex in shape, and the top of the fixing member has a rounded corner.

[0011] By adopting the above technical solution, during the process of the positioning component and the fixing component cooperating, the rounded corner of the fixing component can facilitate the fixing component to be inserted into the hole of the positioning component, and the bevel of the positioning component can facilitate the release of the fixing component and the positioning component from the fixed state.

[0012] Optionally, the top opening of the positioning member is beveled.

[0013] By adopting the above technical solution, the beveled angle of the top opening of the positioning component can facilitate the positioning component and the fixing component to quickly enter the fixing state. Attached Figure Description

The stirring assembly includes a fixing feature 24 fixed on the lifting rod 12, a positioning component 23 fixedly engaged with the fixing feature 24 and a stirring component 26 fixed to the bottom of the positioning component 23. The fixing feature 24 includes an inner cavity and a plurality of fixing components 241 slidably disposed in the inner cavity and a return component 242 disposed between two fixing components 241.

[0020] See Figure 1 Figure 2 Figure 3 The lifting rod 11 is driven to move vertically upward, which in turn moves the stirring rod 26 upward to a position close to the top of the storage tank 21. The by-product sodium acetate solution or by-product sodium acetate crystals are placed in the storage tank 21, and an aqueous solution is added to mix them. The lifting rod 12 is then driven to move vertically downward for a preset distance, allowing the stirring rod 26 to enter the mixture. The motor is then started to rotate, causing the stirring rod 26 to rotate. The stirring rod 26 breaks up the by-product sodium acetate crystals on the uppermost layer of the mixture. After a preset time of breaking up, the stirring paddle is also fully submerged in the mixture for mixing and stirring. After a preset time of breaking up and stirring, the lifting rod 11 is driven to move vertically downward for a preset distance, allowing the stirring rod 26 to break up the by-product sodium acetate crystals on the lowermost layer of the mixture. Simultaneously, the stirring paddle stirs the mixture until it is completely dissolved. After dissolution, the dissolved mixture can be discharged through the outlet valve 25.

[0021] In some embodiments, the heating tube 22 is spirally fixed to the inner wall of the storage tank 21, and the outlet and inlet of the heating tube 22 are respectively fixed to the bottom and top of the storage tank 21.

[0022] In fact, the water inlet of the heating tube 22 is located at the top of the storage tank 21. Hot water is introduced into the water inlet of the heating tube 22 and enters the heating tube 22. The high temperature can accelerate the dissolution of the by-product sodium acetate with water. For example, when the water temperature is 25°C, about 36g of sodium acetate can be dissolved per kilogram of water, while when the water temperature is 100°C, about 100g of sodium acetate can be dissolved per kilogram of water. Therefore, heating the by-product sodium acetate mixture can effectively increase the dissolution rate. At the same time, attaching the heating tube 22 to the inner wall of the storage tank 21 can increase the heating rate of the by-product sodium acetate mixture.

[0023] In some embodiments, the positioning member 23 and the fixing member 241 are provided with an oblique angle at their mating positions, the fixing member 241 is convex in shape, and the top of the fixing member 241 is provided with a rounded corner.

[0024] In fact, during the engagement of the positioning member 23 and the fixing member 241, the rounded corner of the fixing member 241 facilitates the insertion of the fixing member 241 into the hole of the positioning member 23. In addition, the bevel of the positioning member 23 facilitates the release of the fixing state of the fixing member 241 and the positioning member 23.

[0025] In some embodiments, the top opening of the positioning member 23 is beveled.

[0026] In fact, the beveled opening at the top of the positioning member 23 facilitates the quick entry of the positioning member 23 and the fixing member 241 into the fixed state.

[0027] Although the embodiments of this utility model have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations fall within the scope and spirit of this utility model as described in the claims.
