Technical Field

[0001] The utility model belongs to the technical field of sodium acetate production, and particularly relates to a by-product sodium acetate dissolving device. Background Art

[0002] In the water treatment industry, sodium acetate trihydrate (also known as sodium acetate trihydrate) is usually used as an effective carbon source in the biochemical treatment system for wastewater purification. Because it has a single molecular formula and molecular structure and is easy to be utilized by microorganisms, it is often used as a carbon source to provide nutrients for the growth and metabolism of microorganisms in the sewage biochemical treatment system, improving the biodegradability of the biochemical denitrification and nitrogen removal process of sewage.

[0003] Sodium acetate trihydrate can be prepared from by-product sodium acetate (also known as sodium acetate mother liquor). By-product sodium acetate is a waste produced in the factory production process, which not only contains various salt substances, organic substances, but also has many heavy metal substances. It not only pollutes the environment but also causes waste of resources. Therefore, by-product sodium acetate is recycled, and through processes such as impurity removal and centrifugation, sodium acetate trihydrate is prepared for use in the water treatment industry.

[0004] During the production and preparation of by-product sodium acetate, it is necessary to dissolve by-product sodium acetate. By-product sodium acetate is solid at room temperature, such as powder, broken block crystal, large block crystal, and part of by-product sodium acetate is in solution. During the dissolution process, by-product sodium acetate and water are mixed to form a mixed solution, which is added to the dissolution tank for dissolution. To accelerate the dissolution rate, the dissolution tank is equipped with a stirring paddle. However, during the initial dissolution process, due to the presence of undissolved large block crystal by-product sodium acetate in the mixed solution, during the stirring process of the stirring paddle, the stirring paddle collides with the undissolved large block crystal by-product sodium acetate, and during the long-term collision process, the stirring paddle will be bent, and the connection part of the stirring paddle will become loose, resulting in a high damage rate of the stirring paddle.

For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0027] Please refer to Figures 1 to 7 , a by-product sodium acetate dissolving device, including a dissolving tank 100 and an adjustable stirring assembly 200. A seat body 110 is arranged at the bottom of the dissolving tank 100, and the seat body 110 fixes and supports the dissolving tank 100. A detachable cover body 140 is arranged at the top of the dissolving tank 100, and a liquid discharge port 150 is opened at the bottom of the dissolving tank 100. The adjustable stirring assembly 200 includes a connecting shaft 210, a stirring paddle 220, a crushing paddle 230, a driving motor 240 and a lifting member 250. The connecting shaft 210 is vertically suspended in the dissolving tank 100. The stirring paddle 220 is installed on the connecting shaft 210 and is located inside the dissolving tank 100. The crushing paddle 230 is installed on the connecting shaft 210 and is located below the stirring paddle 220. The driving motor 240 is arranged at one end of the connecting shaft 210, and the lifting member 250 is connected to the driving motor 240 and drives the driving motor 240 to move up and down in the vertical direction.

[0028] The dissolving tank 100 is an existing tank for dissolving by-product sodium acetate. Open the cover body 140, place the by-product sodium acetate solution or by-product sodium acetate crystals in the dissolving tank 100, add an aqueous solution, and make the two mix to form a mixed solution. For the dissolved mixed solution, even if the mixed solution contains a large amount of impurities, it does not matter. Only the by-product sodium acetate solution needs to be dissolved, and the subsequent process will remove the impurities in the mixed solution.

[0029] The crushing paddle 230 is a relatively hard paddle blade, with relatively low stirring efficiency but strong crushing effect and not easily damaged.

[0030] The lifting member 250 is a driving member that can rise in the vertical direction, which can be a pushing cylinder or an electric push rod.

[0031] The specific working process is as follows:

[0032] Drive the lifting member 250 to move vertically upward, drive the stirring paddle 220 to move upward, and move to a position close to the top of the dissolution tank 100. Open the cover body 140, place the by-product sodium acetate solution or the by-product sodium acetate crystal in the dissolution tank 100, add an aqueous solution, and mix the two. Close the cover body 140 to make the dissolution tank 100 in a closed state. Drive the lifting member 250 to move again and move vertically downward for a preset distance. First, make the crushing paddle 230 enter the mixed solution, start the motor to rotate, drive the crushing paddle 230 to rotate, and the crushing paddle 230 crushes the by-product sodium acetate crystal existing in the uppermost layer of the mixed solution. After crushing for a preset time, drive the lifting member 250 to move again and move vertically downward for a preset distance. The crushing paddle 230 crushes the by-product sodium acetate crystal existing in the middle layer of the mixed solution. After crushing for a preset time, drive the lifting member 250 to move again and move vertically downward for a preset distance. The crushing paddle 230 crushes the by-product sodium acetate crystal existing in the middle layer of the mixed solution. At the same time, the stirring paddle 220 also completely immerses in the mixed solution for mixing and stirring. After crushing and stirring for a preset time, drive the lifting member 250 to move again and move vertically downward for a preset distance. The crushing paddle 230 crushes the by-product sodium acetate crystal existing in the lowermost layer of the mixed solution. At the same time, the stirring paddle 220 stirs the mixed solution until all are dissolved.

[0033] Achieved effects:

[0034] By adding the crushing paddle 230 and the lifting member 250, the lifting member 250 drives the crushing paddle 230 and the stirring paddle 220 to move up and down in the vertical direction, so that the crushing paddle 230 first crushes the large crystal by-product sodium acetate into small crystal by-product sodium acetate, accelerates the dissolution of the by-product sodium acetate crystal, improves the dissolution rate. At the same time, it avoids the collision between the stirring paddle 220 and the large crystal by-product sodium acetate, prevents the damage of the stirring paddle 220, and prolongs the service life of the stirring paddle 220.

[0035] Further, refer to Figure 3 and Figure 4, the crushing paddle 230 includes a mounting plate 231, a first crushing rod 232 and a second crushing rod 233. The mounting plate 231 is arranged at one end of the coupling shaft 210 and on the side away from the driving motor 240. The first crushing rod 232 is detachably arranged on the mounting plate 231, and the second crushing rod 233 is detachably arranged on the mounting plate 231. A plurality of the first crushing rods 232 and / or the second crushing rods 233 can be arranged on the mounting plate 231. The first crushing rod 232 and the second crushing rod 233 are made of a material with high hardness, such as steel bars. A gap is reserved between the first crushing rod 232 and the second crushing rod 233. By providing the first crushing rod 232 and the second crushing rod 233, when the first crushing rod 232 and the second crushing rod 233 rotate, they can collide with the large crystal by-product sodium acetate, so as to break the large crystal by-product sodium acetate, thereby improving the crushing efficiency of the large crystal by-product sodium acetate. At the same time, the reserved gap can enable the crushed small crystal by-product sodium acetate to pass through the gap, preventing the by-product sodium acetate crystal block from being stuck between the first crushing rod 232 and the second crushing rod 233 and affecting the crushing efficiency of the crystal by-product sodium acetate.

[0036] Furthermore, the first crushing rod 232 includes a first straight rod 2321 and a first curved rod 2322. One end of the first straight rod 2321 is connected to the mounting plate 231, and the first curved rod 2322 is connected to the other end of the first straight rod 2321. The bending direction of the first curved rod 2322 is the same as the rotation direction of the coupling shaft 210. When the first straight rod 2321 and / or the first curved rod 2322 collide with the large crystal by-product sodium acetate and do not break the large crystal by-product sodium acetate, under the centrifugal rotation state of the mixed liquid, the large crystal by-product sodium acetate will rotate towards the side of the first curved rod 2322 and rotate to the rear, and will be continuously collided by the first straight rod 2321 and the first curved rod 2322 that rotate again, so as to break the large crystal by-product sodium acetate, avoiding the first crushing rod 232 from continuously driving the large crystal by-product sodium acetate to rotate.

[0037] For further description, see Figure 1, the lifting member 250 includes a support platform 251, a driving cylinder 252 and a bridge plate 253. The support platform 251 is installed on one side of the dissolution tank 100. The driving cylinder 252 is arranged on the support platform 251. One end of the bridge plate 253 is connected to the driving cylinder 252, and the other end of the bridge plate 253 is connected to the driving motor 240. The support platform 251 is used to lift the driving cylinder 252. The staff controls the driving cylinder 252 to move up and down in the vertical direction. The bridge plate 253 has a bridging function and connects the driving cylinder 252 and the coupling shaft 210 at the same time. That is, when the driving cylinder 252 rises, it drives the coupling shaft 210 to rise, and when the driving cylinder 252 descends, it drives the coupling shaft 210 to descend.

[0038] In a possible embodiment, refer to Figure 6 , in order to accelerate the dissolution of by-product sodium acetate, a first coil 120 is arranged in the dissolution tank 100. The first coil 120 is attached to the inner wall of the dissolution tank 100. The water inlet end and the water outlet end of the first coil 120 penetrate through the dissolution tank 100 and extend to the outside of the dissolution tank 100. The water inlet end of the first coil 120 is located at the bottom of the dissolution tank 100, and the water inlet end of the first coil 120 is located at the top of the dissolution tank 100. Hot water is introduced into the water inlet end of the first coil 120 and enters the first coil 120. High temperature can accelerate the mutual dissolution of by-product sodium acetate and water. For example, when the water temperature is 25 °C, about 36 g of sodium acetate can be dissolved in each kilogram of water, and when the water temperature is 100 °C, about 100 g of sodium acetate can be dissolved in each kilogram of water. Therefore, heating the by-product sodium acetate mixed solution can effectively improve the dissolution rate. At the same time, attaching the first coil 120 to the inner wall of the dissolution tank 100 can increase the heating speed of the by-product sodium acetate mixed solution.

[0039] Furthermore, a first valve 121 is arranged on the water inlet end of the first coil 120. The first valve 121 can control the flow rate of the hot water in the first coil 120.

[0040] Further, in order to further accelerate the dissolution rate of by-product sodium acetate in the dissolution tank 100 and improve the process efficiency, a second coil pipe 130 is further arranged in the dissolution tank 100. The second coil pipe 130 is attached to the inner wall of the dissolution tank 100. The second coil pipe 130 is arranged in a staggered manner with the first coil pipe 120. The water inlet end and the water outlet end of the second coil pipe 130 penetrate through the dissolution tank 100 and extend to the outside of the dissolution tank 100. After the first coil pipe 120 is opened for a preset time, the second coil pipe 130 is opened. The by-product sodium acetate mixed solution is heated by the first coil pipe 120 and the second coil pipe 130 at the same time, so that the by-product sodium acetate mixed solution is heated to a preset temperature and the preset temperature is maintained. When the preset temperature is maintained, the second coil pipe 130 is closed, and the preset temperature is maintained by the first coil pipe 120. When by-product sodium acetate is added into the dissolution tank 100 again, the second coil pipe 130 is opened to rapidly heat and dissolve it.

[0041] Furthermore, a second valve 131 is arranged on the water inlet end of the second coil pipe 130. The second valve 131 can control the hot water flow rate in the second coil pipe 130.

[0042] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
