Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a salt bath for producing high-quality saturated brine. Background Technology

[0002] In industrial production, the preparation of saturated brine is a crucial step in many processes, and it is currently commonly carried out using concrete tanks and mechanical mixers. However, this method has the following problems, which restrict further improvements in brine quality and preparation efficiency.

[0003] (1) Quality issues: During the feeding process, nylon bag residue and impurities on the surface of the pool are easily carried into the salt bath, which reduces the quality of the brine and affects the operation of the conveying equipment.

[0004] (2) Saturation problem: The solubility of salt is affected by many factors such as temperature and pressure. Therefore, it is difficult to calculate the accurate amount of salt to be added in the actual production process. If too little salt is added, the concentration will be insufficient. If too much salt is added, it will result in waste and the salt particles will enter the downstream production process, which will further affect the production quality.

[0005] (3) Liquid level control problem: Due to the presence of a stirrer, the fluctuation of the liquid level has a certain impact, making it difficult to remotely monitor and control the actual liquid level.

[0006] CN107285430A discloses a brine treatment tank and a chlor-alkali brine treatment system. The brine treatment tank includes a brine outlet and a salt layer laid at the bottom of the tank's inner cavity, with a brine collection pipe disposed within the salt layer. The outlet end of the brine collection pipe is connected to the inlet end of the brine outlet, and the pipe has multiple holes. This salt layer can filter saturated brine before it enters the brine outlet, effectively reducing the amount of sediment and fine salt particles carried in the discharged brine and preventing blockages in the brine pipes and downstream equipment. However, the salt layer in this brine treatment tank still cannot ensure effective filtration of other impurities, and the actual liquid level cannot be monitored.

[0007] Therefore, there is an urgent need to develop a new type of brine that can guarantee the quality of brine and more accurately monitor the brine level. Utility Model Content

[0008] The purpose of this invention is to overcome at least one of the defects of the existing technology, namely, the difficulty in ensuring the quality of saturated brine and the inability to accurately monitor the liquid level of the brine pool, and to provide a brine pool for producing high-quality saturated brine.

[0009] The objective of this utility model can be achieved through the following technical solutions: This utility model provides a salt-making tank for producing high-quality saturated brine, the salt-making tank including a main salt-making tank and a discharge tank that are set up independently; The bottom of the main salt tank is covered with a sand filter layer for filtering impurities, and a stirrer is installed on the top of the main salt tank. The discharge tank is equipped with a level gauge for monitoring the liquid level; The main brine tank and the discharge tank are connected by a first connecting pipe and a second connecting pipe; wherein, the first connecting pipe is laid horizontally in the sand filter layer and has several brine input holes along the axial direction, the first connecting pipe is connected to the second connecting pipe at one end of the discharge tank, and the first connecting pipe is connected to the air inlet pipe at one end of the main brine tank.

[0010] Furthermore, the thickness of the sand filter layer is 250~350 mm.

[0011] Furthermore, the sand filter layer is composed of quartz sand with a particle size of 1-2 mm.

[0012] Furthermore, the diameter of the brine inlet on the first connecting pipe is 3~5 mm.

[0013] Furthermore, the first connecting pipe has salt water inlet holes at equal intervals on both sides along the axial direction.

[0014] Furthermore, the first connecting pipe is provided in multiple parts, and the end of the first connecting pipe away from the discharge pool is connected to the main pipe.

[0015] Furthermore, the main pipe has a connection port in the middle, and the end of the air intake pipe is connected to the main pipe through the connection port.

[0016] Furthermore, the first connecting pipe and the second connecting pipe, as well as the first connecting pipe and the main pipe, are connected by bends.

[0017] Furthermore, the end of the first connecting pipe extending into the discharge pool is connected to the upward-extending second connecting pipe.

[0018] Furthermore, the outlet end of the second connecting pipe is an external thread interface, and the outlet end is detachably connected to the internal thread end cap.

[0019] Compared with the prior art, the present invention has the following technical advantages: This invention ensures brine saturation and reduces material waste by separating the main brine tank and the discharge tank. Furthermore, the absence of a stirrer in the discharge tank avoids the influence of a stirrer on the accurate level reading of the level gauge. In addition, the bottom of the main brine tank features a sand filter layer, which, together with the integrated first connecting pipe, forms a highly efficient filtration system. This system effectively traps and filters impurities and other insoluble substances that may be introduced during salt addition. Undissolved salt particles are retained within the main brine tank by the sand filter layer and continue to dissolve. Through the combined use of these components, this invention effectively ensures the quality of the saturated brine, accurately monitors the brine tank level, and enables efficient production of saturated brine.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1: This embodiment provides a salt treatment pond for producing high-quality saturated brine.

[0028] like Figure 1-3 As shown, the brine tank in this embodiment includes a main brine tank 1 and a discharge tank 2, which are set up independently. The bottom of the main brine tank 1 is covered with a sand filter layer 4 for filtering impurities, and a stirrer 5 is installed on the top of the main brine tank 1. A level gauge 6 is installed in the discharge tank 2 for monitoring the liquid level of the discharge tank 2.

[0029] In this embodiment, the main brine tank 1 and the discharge tank 2 are connected by a first connecting pipe 3 and a second connecting pipe 7. The first connecting pipe 3 is horizontally laid within the sand filter layer 4 and has several brine inlet holes 3.1 along its axial direction. One end of the first connecting pipe 3 in the discharge tank 2 is connected to the second connecting pipe 7, and one end of the first connecting pipe 3 in the main brine tank 1 is connected to the air inlet pipe 8.

[0030] This embodiment ensures brine saturation and reduces material waste by separating the main brine tank 1 and the discharge tank 2. Furthermore, since the discharge tank 2 lacks a stirrer 5, it avoids the influence of the stirrer 5 on the accurate level reading of the level gauge 6. In addition, the bottom of the main brine tank 1, equipped with a sand filter layer 4, together with the first connecting pipe 3, forms a highly efficient filtration system. This system effectively traps and filters out impurities and other insoluble substances that may be introduced during salt addition. Undissolved salt particles are trapped within the main brine tank 1 by the sand filter layer 4 and continue to dissolve. The ingenious coordination of these components effectively ensures the quality of the saturated brine, accurately monitors the brine tank level, and achieves efficient production of saturated brine.

[0031] Example 2: This embodiment provides a salt treatment tank for producing high-quality saturated brine, specifically consisting of a main salt treatment tank 1, a discharge tank 2, a first connecting pipe 3, a sand filter layer 4, a stirrer 5, a level gauge 6, a second connecting pipe 7, an air inlet pipe 8, an internal threaded end cap 9, a main pipe 10, and a bend pipe 11.

[0032] In this embodiment, the main salt tank 1 and the discharge tank 2 are set up independently and are separated by a partition wall.

[0033] In this embodiment, the bottom of the main brine tank 1 is covered with a sand filter layer 4 for filtering impurities. The sand filter layer 4 is composed of quartz sand with a particle size of 1-2 mm, and the thickness of the sand filter layer 4 is 250-350 mm, preferably 300 mm. A stirrer 5 is installed at the top of the main brine tank 1 to accelerate the dissolution of solid salt and make the salt solution more uniformly mixed. The brine tank in this embodiment creatively achieves self-regulation and protection of brine saturation. Due to its high density, the saturated brine with sufficient dissolved salt will naturally sink and pass through the sand filter layer 4 into the first connecting pipe 3, and then be transported to the discharge tank 2.

[0034] In this embodiment, the discharge tank 2 is equipped with a level gauge 6. The level gauge 6 monitors the liquid level in the discharge tank 2 and provides a signal to interlock the corresponding discharge equipment. This embodiment physically separates the main brine tank 1 with a stirrer 5 from the discharge tank 2, completely isolating the surface fluctuations and eddies generated during the stirring process within the main brine tank 1. This ensures that the level gauge 6 in the discharge tank 2 can obtain highly accurate and stable readings. This provides a reliable data foundation for remote monitoring and automated control, greatly improving the accuracy and reliability of the entire system's level control.

[0035] In this embodiment, the main brine tank 1 and the discharge tank 2 are connected by a pipeline system consisting of several first connecting pipes 3 and several second connecting pipes 7. The first connecting pipes 3 are all laid horizontally in the sand filter layer 4. One end of the first connecting pipe 3 in the discharge tank 2 is connected to the second connecting pipe 7, and one end of the first connecting pipe 3 in the main brine tank 1 is connected to the air inlet pipe 8.

[0036] In this embodiment, the first connecting pipe 3 has several brine inlet holes 3.1 evenly spaced on both sides along the axial direction. The diameter of the brine inlet holes 3.1 is 3~5 mm, and the top is sealed with a pipe cap. The number of holes is set as needed.

[0037] To facilitate the convergence of multiple first connecting pipes 3, the ends of each first connecting pipe 3 furthest from the discharge pool 2 are connected to the main pipe 10. The main pipe 10 has a connection port in its middle, and the end of the air inlet pipe 8 is connected to the main pipe 10 through this connection port. In this embodiment, the first connecting pipe 3 and the second connecting pipe 7, as well as the first connecting pipe 3 and the main pipe 10, are connected by bends 11. The first connecting pipe 3, the second connecting pipe 7, the main pipe 10, and the bends 11 can all be made of conventional UPVC pipes.

[0038] In this embodiment, the outlet end of the second connecting pipe 7 is an external threaded interface, and the outlet end is detachably connected to the internal threaded end cap 9. In the event of blockage of the first connecting pipe 3 in this embodiment, the internal threaded end cap 9 can be tightened to the second connecting pipe 7, and then compressed air can be introduced through the air inlet pipe 8 for backwashing.

[0039] The working principle of the salt treatment tank in this embodiment is as follows: Salting is carried out in the main brine tank 1 by agitator 5, with an excess of solid salt (amount higher than that used to prepare saturated brine for both salt tanks) added to the main brine tank 1. Due to the presence of the sand filter layer 4, impurities are filtered out, and the excess salt remains in the main brine tank 1. The main brine tank 1 is filled with water and stirred until the liquid level is slightly below the top of the second connecting pipe 7. After thorough stirring, water is continued to be added to the main brine tank 1, while the agitator 5 continues to operate. Because of the high density of the saturated brine, it enters the first connecting pipe 3 through the brine inlet 3.1 at the bottom, and then flows into the discharge tank 2. Since the discharge tank 2 does not require an agitator, the level gauge 6 in the discharge tank 2 is not affected by the agitator's disturbance, resulting in a more accurate level reading. If the first connecting pipe 3 becomes blocked, it can be tightened with the second connecting pipe 7 using the internal threaded end cap 9, and compressed air is introduced through the air inlet pipe 8 for backwashing.

[0040] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
