The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0026] When the salt solution in the current configuration device is exhausted or needs to be replaced, it is necessary to stop outputting the salt solution and dissolve the salt particles in pure water again by stirring. This method is more time-consuming. Therefore, the utility model designs such an automatic salt concentration configuration system;

[0027] Embodiment 1:

[0028] like Figure 1As shown, it includes a configuration barrel 2, on which a first pipe 3 and a second pipe 4 are provided, the first pipe 3 is used to input pure water into the configuration barrel 2, and the second pipe 4 is used to output the salt solution in the configuration barrel 2 to the salt spray chamber, and also includes a saturation barrel 1, on which a third pipe 5 and a fourth pipe 6 are provided, the third pipe 5 is used to input pure water into the saturation barrel 1, and the fourth pipe 6 is used to input the saturated salt solution in the saturation barrel 1 into the configuration barrel 2, and high-precision metering pumps are provided on the first pipe 3, the second pipe 4, the third pipe 5 and the fourth pipe 6. In order to facilitate the control of the solution in the barrel and the high-precision For the control of the metering pump, a first liquid level sensor 7 is provided in the saturated barrel 1, and a second liquid level sensor 8 is provided in the configuration barrel 2. The first liquid level sensor 7 is used to detect the amount of solution in the saturated barrel 1, and the second liquid level sensor 8 is used to detect the amount of solution in the configuration barrel 2. Compared with the traditional salt solution configuration device, the saturated barrel 1 added in the utility model can continuously transport the dissolved high-concentration salt solution to the configuration barrel 2 to increase the configuration speed of the salt solution of the required concentration, and then control the amount of solution in the barrel by the height of the liquid level to ensure that the salt concentration in the saturated barrel 1 is always saturated and consistent.

[0029] In addition, the first liquid level sensor 7 and the second liquid level sensor 8 in the present invention are both two ball valve components, and the two ball valve components in the saturation barrel 1 and the two ball valve components in the configuration barrel 2 are both arranged with a height difference.

[0030] Its working principle is as follows: define the high-precision metering pump on the first pipe fitting 3 as A, the one on the second pipe fitting 4 as B, the one on the third pipe fitting 5 as C, and the one on the fourth pipe fitting 6 as D. Define the two ball valves in the saturated barrel 1 as A1 and B1, and the two ball valves in the configuration barrel 2 as C1 and D1; when the water level in the saturated barrel 1 is lower than A1, open C to inject pure water into the saturated barrel 1, and when the water level is higher than B1, close C to stop injecting pure water. At this time, the salt content in the saturated barrel 1 always reaches a saturated state, and there is undissolved salt in the solution. When the water level in the configuration barrel 2 is lower than C1, open A and D at the same time, and the saturated brine and pure water in the saturated barrel 1 are injected into the configuration barrel 2 at the same time. At this time, it is only necessary to control the flow ratio of A and D, and control the injection flow rate ratio of the two, that is, to achieve the salt concentration content in the configuration barrel 2. When the water level in the configuration barrel 2 reaches D1, close A and D at the same time. When the configured salt solution needs to be used, open B to extract the configured salt solution into the salt spray chamber.

[0031] In order to make the salt solution in the saturation barrel 1 always reach a saturated state, salt needs to be replenished at the same time when pure water is injected. Therefore, the saturation barrel 1 also includes a salt replenishing structure, which can continuously replenish salt into the saturation barrel 1.

[0032] Specifically, Figure 2As shown, the salt replenishing structure includes a salt storage container 9 arranged on the outer side wall of the upper end of the saturated barrel 1, and salt particles (granular salt particles) are placed in the salt storage container 9. A salt drop opening 10 communicating with the salt storage container 9 is opened on the side wall of the saturated barrel 1, and a switch door 11 for opening and closing the salt drop opening 10 is provided on the salt storage container 9. The inner bottom surface of the salt storage container 9 is inclined toward one end of the salt drop opening 10. When the switch door 11 is automatically opened, the salt particles inside will slide into the saturated barrel 1 from the salt drop opening 10 because the bottom surface of the salt storage container 9 is an inclined surface. In addition, a salt pushing mechanism or a shaking mechanism can be arranged in the salt storage container 9, and the salt particles can be pushed into the saturated barrel 1 by the salt pushing mechanism, or the salt particles can be shaken into the saturated barrel 1 by the shaking mechanism.

[0033] Correspondingly, a stirring mechanism may be provided in the saturation barrel 1 to continuously stir the saturation barrel 1 so that the salt concentration in the saturation barrel 1 reaches a saturated state.

[0034] Embodiment 2:

[0035] On the basis of Example 1, the salt replenishing mechanism is replaced by a placing box 13, as shown in the following example. Figure 3 As shown, a salt block (a salt block with larger particles) is placed in the placing box 13, and a plurality of dispersion holes are opened on the side wall of the placing box 13. When the solution penetrates the placing box 13, the solution enters the dispersion holes and contacts the salt block to dissolve the surface of the salt block, so that the salt content of the solution reaches saturation.

[0036] A pair of pull rods 12 are provided on the side walls of the placement box 13, and a snap ring detachably connected to the placement box 13 is provided on the pull rod 12, that is, the snap ring can limit the relative position of the pull rod 12 and the placement box 13, and a hook is provided at the end of the pull rod 12 away from the placement box 13, and the hooks of the two pull rods 12 are in opposite directions. The two hooks can be hooked on the upper opening edges of the saturation barrel 1 respectively, so that the placement box 13 is suspended inside the saturation barrel 1. When the salt block in the placement box 13 is too little dissolved, the pull rod 12 can be lifted upward to make the placement box 13 out of the saturation barrel 1, and the salt block in the placement box 13 can be replaced.

[0037] In order to limit the position of the placement box 13 and prevent the placement box 13 from shaking in the saturation barrel 1, as shown in FIG. Figure 4 As shown, an avoidance groove 16 cooperating with the hook is provided on the edge of the upper opening of the saturation barrel 1, and a limiting groove 15 for inserting the end of the hook is also provided on the side wall of the saturation barrel 1. The placement box 13 is limited by limiting the position of the pull rod 12. In addition, when the hook of the pull rod 12 is located in the avoidance groove 16, the end of the hook can be inserted into the limiting groove 15. If the strength of the pull rod 12 is too high and the tightness in the limiting groove 15 is greater, the hook at this time can also be used as a lifting ear of the saturation barrel 1.

[0038] In addition, in order to fix the two pull rods 12, a connecting rod is provided between the two pull rods 12 for position limiting and reinforcement.

[0039] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
