[0002] In the production of ion membrane caustic soda, dissolving raw salt into saturated brine is an important process that affects ion membrane electrolysis. The current traditional salt dissolving process is that solid salt falls into the salt dissolving barrel through a conveyor or a forklift, and the water distributor continuously sprays hot water at the bottom of the salt dissolving barrel to dissolve the solid salt, and the brine overflows from the upper part of the salt dissolving barrel into the baffle tank.
[0003] Due to the different qualities of raw salt, there are bound to be powdered or fine particles in the raw salt. This type of raw salt is easy to float during the dissolution process. The current structure of the salt tank is limited, and the flow rate at the overflow terminal of the salt tank overflow port is large. The fine salt particles are entrained by the brine overflow into the baffle trough and the subsequent salt dissolution process before they have time to dissolve. The fine salt particles seriously scour and corrode the coarse brine pump and the coarse brine pipeline, causing equipment damage and affecting normal production operations. Utility Model Content
[0004] Purpose of the utility model: The purpose of the utility model is to provide a salt tank that can solve the corrosion problem of the inside of the coarse brine pump and the transportation pipeline and reduce the fine salt in the brine.

[0006] Wherein, the upper edge of the barrel body is flush with the top of the overflow trough.
[0007] Wherein, a support frame is provided between the lower part of the overflow trough and the outer wall of the cylinder.
[0008] Wherein, the support frame is welded to the embedded pad fixed to the side wall of the cylinder.
[0009] Wherein, inner angle grooves are respectively provided at corresponding positions of the bottom of the fixing plate and the top of the overflow groove, so as to enable the bottom of the fixing plate and the top of the overflow groove to be tightly welded.
[0010] Among them, the screen is provided with reinforcement rings for supporting the screen at intervals along the circumferential direction, and the screen is fixed between the fixing plate and the reinforcement ring; the positions of the fixing plate and the reinforcement ring correspond one to one; screw holes are respectively provided at corresponding positions of the upper and lower parts of the fixing plate and the reinforcement ring, and the screen is fixed to the top of the overflow trough by inserting bolts into the screw holes and tightening nuts.
[0011] Among them, the material of the body of the brine dissolving tank is metal and anti-corrosion material, or it is a concrete structure; the material of the overflow tank is metal and anti-corrosion material.
[0012] Among them, when the body of the brine dissolving tank is a concrete structure, the overflow tank backing plate is embedded in the concrete.
[0013] Among them, the overflow tank is detachably arranged, which is convenient for later cleaning or replacing the screen.
[0014] Beneficial effects: Compared with the prior art, the present utility model has the following remarkable effects: The present utility model is provided with an overflow tank on the outer periphery of the top of the body of the brine dissolving tank. The top of the overflow tank is open, and an overflow ring is provided upward around the top of the overflow tank. The overflow ring includes a screen surrounding the circumference of the top of the overflow tank; the cooperation of the overflow tank and the overflow ring enables the brine carrying fine salt particles in the brine dissolving tank to overflow into the overflow tank, reducing the terminal flow velocity of the overflow of the crude brine, causing the relatively large-diameter fine particles to settle in the overflow tank, and the overflow ring at the top of the overflow tank can filter the settled crude brine and then flow into the baffle tank in the prior art or the subsequent processes of brine dissolving. Therefore, the device of the present utility model reduces the particle size of the fine salt particles carried by the crude brine and the amount of entrained fine salt, solves the problem of a large amount of fine salt entrained by the crude brine, and alleviates the problems of internal abrasion of the crude salt water pump and erosion of the pipeline.

[0019] The technical solution of the present utility model will be further described below in conjunction with the drawings in the specification.
[0020] Such as Figure 1As shown in the figure, the utility model provides a brine dissolving tank for reducing fine salt carried by brine, which comprises a tank body 1. An overflow tank 4 is arranged on the outer periphery of the top of the tank body 1, and an overflow ring 6 is arranged on the top of the overflow tank 4. The overflow tank 4 is used for enabling the coarse brine carrying fine salt particles to overflow from the top of the tank body 1 into the overflow tank 4 and enabling the fine salt particles to settle. The overflow ring 6 is used for enabling the coarse brine to flow out after filtering fine salt particles. The upper edge of the tank body 1 is higher than the bottom of the overflow tank 4 and is flush with the top of the overflow tank 4. A support frame 5 is arranged between the lower part of the overflow tank 4 and the outer wall of the cylinder. The support frame 5 is welded on a pre-buried backing plate 3 fixed on the side wall of the cylinder body.
[0021] As Figure 2 , 3 shown, the overflow ring 6 comprises a screen 6-2 arranged around the top of the overflow tank. A fixing plate 6-1 and a reinforcing ring 6-3 are respectively arranged at intervals along the outer peripheral direction of the cylinder body. The positions of the fixing plate 6-1 and the reinforcing ring 6-3 correspond to each other one by one. The screen 6-2 can be directly fixed on the fixing plate 6-1. In this embodiment, the screen 6-2 is fixed between the fixing plate 6-1 and the reinforcing ring 6-3. In this embodiment, screw holes are respectively opened at the corresponding positions of the upper and lower parts of the fixing plate 6-1 and the reinforcing ring 6-3. Bolts 6-4 are respectively inserted into the screw holes of the upper and lower parts, and the screen 6-2 is fixed on the top of the overflow tank by using tightening nuts 6-5. Inner corner bevels 7 are respectively opened at the corresponding positions of the bottom of the fixing plate 6-1 and the top of the overflow tank 4 for enabling the bottom of the fixing plate 6-1 to be tightly welded to the top of the overflow tank 4.
[0022] The material of the brine dissolving tank body 1 is metal and anti-corrosion material, or is a concrete structure. The material of the overflow tank 4 is metal and anti-corrosion material. When the brine dissolving tank body 1 is a concrete structure, the pre-buried backing plate is pre-buried into the concrete. The overflow tank 4 is detachably arranged, which is convenient for later cleaning or replacing the screen.
[0023] In this embodiment, a water distributor 2 is arranged in the tank body 1, which comprises a conveying main pipe for connecting a water source and a shunt nozzle arranged on the conveying main pipe. The structure of the water distributor 2 is as Figure 4 shown in (a) and (b) of Figure 4 . The conveying main pipe of the water distributor 2 can form a circle as shown in (a) of Figure 4 , or form a rectangle as shown in (b) of
[0024] . The shape surrounded by the conveying main pipe can be diversified. A plurality of shunt nozzles are welded on the conveying main pipe, which is convenient for uniformly distributing the brine for dissolving salt. The raw salt is dissolved in the hot water sprayed by the water distributor 2 in the tank body 1. Fine particles of fine salt float on the upper part and the surface of the brine in the brine dissolving tank. The coarse brine carrying fine salt particles overflows from the top of the brine dissolving tank into the overflow tank 4 and flows into the baffle tank through the overflow ring 6. In the overflow tank 4, the overflow terminal velocity of the coarse brine is reduced, the fine particles with larger diameters settle, the particle size of the fine salt particles carried by the coarse brine is reduced, and the amount of entrained fine salt is reduced.
