Detailed Description
The invention will be described in further detail below with reference to the drawings and specific examples.
As shown in fig. 1: a device for reducing refined brine suspended matters comprises a first refined brine barrel, wherein the lower part of the first refined brine barrel is of a cone structure, and a pumping device for pumping and draining sediments is arranged at the cone structure; the height of the feeding hole of the first refined brine barrel is lower than that of the discharging hole of the first refined brine barrel.
The scheme has the following advantages: the lower part of the first refined brine barrel is of a cone structure, so that mud is precipitated and pumped and discharged; the pumping device is arranged, so that sediments collected by the cone part can be periodically pumped; the feeding hole of the first refined brine barrel is designed to be lower than the discharging hole of the first refined brine barrel, so that the feeding and discharging modes of the refined brine barrel are low in feeding and high out, the water disturbance during feeding can be reduced, and sediments at the bottom of the barrel are prevented from being carried away during discharging.
Specifically, the height of the feed inlet of the first refined brine barrel is arranged below the water level line of the first refined brine barrel. The water level line is the lowest water level line in the refined brine barrel, so that the disturbance to the water body in the material transferring process can be reduced.
The discharge port height of the first refined brine barrel is arranged above the water level line of the first refined brine barrel. The water level line is the lowest water level line in the refined brine barrel. Higher than the water level line, can avoid the discharge gate to take away barrel bottom deposit suction when the refined brine ejection of compact.
In this embodiment, the first refined brine barrel is newly added on the basis of the original refined brine barrel, rather than completely changing the original structure, that is, two refined brine barrels are usually adopted to separate refined brine in the prior art, that is, the second refined brine barrel and the third refined brine barrel; the second refined brine barrel is communicated with the third refined brine barrel through a communicating pipe. The feed inlet of the first refined brine barrel is connected with the reaction barrel; the lower part of the first refined brine barrel is provided with a slag discharge pipeline which is connected with the other reaction barrel through the pumping device. Because the first refined brine barrel is in a lower-in and higher-out mode, the height of the feeding hole of the second refined brine barrel is higher than that of the discharging hole of the second refined brine barrel, namely the position of a communicating pipe between the second refined brine barrel and the first refined brine barrel is not improved.
In this embodiment, the discharge port of the refined brine barrel at the end is provided with an upward-curved elbow at the part located in the barrel, that is, the third refined brine barrel of this embodiment is located at the end, and therefore an upward-curved elbow is provided at the part of the discharge port located in the barrel. The discharge gate of current terminal smart steamed bucket is the formula of cuting straightly usually, in the pipeline direct access bucket, is the vertical state with the ladle body promptly, now need lifting the height of ejection of compact pipeline in the bucket to the realization changes the disturbance of material process to the barrel head sediment material. Therefore, on the basis of not changing the position of the original discharge hole, the part of the original discharge pipe in the barrel is welded with a 90-degree elbow, and pipelines with different lengths can be welded on the basis of the elbow according to actual needs. Therefore, the lifting can be realized on the basis of not changing the position of the original discharge hole, so that the disturbance of the material transferring process on the sediment at the bottom of the barrel is realized.
A method for reducing fine halogen suspension comprising the steps of:
s101: the refined brine barrel with the cone structure is additionally arranged on the basis of the original refined brine barrel, and the feeding and discharging modes of the refined brine barrel with the cone structure are low in feeding and high out feeding.
Specifically, newly increase first smart steamed bucket on the basis of second smart steamed bucket and third smart steamed bucket, design for the cone structure, the feed inlet and the reaction barrel pipe connection of first smart steamed bucket, the row's of first smart steamed bucket cinder notch is through arranging the sediment pipeline and connecting another reaction barrel through pump drainage device. The three refined brine barrels are sequentially communicated through a communicating pipe, and a discharge port of the first refined brine barrel is connected with salt making equipment.

Preferably, the first refined brine bucket of this embodiment upper portion is the cylinder, and the lower part is the centrum, and the feed inlet is located on the inclined plane of centrum to reduce the disturbance to the water among the material transfer process.
S102: refined brine enters the first refined brine barrel, refined brine clear liquid enters the next original refined brine barrel, suspended matters in the refined brine are left in the refined brine barrel with the cone structure through natural sedimentation, and after the refined brine barrel is continuously produced for a period of time, the suspended matters form sediment in the refined brine barrel with the cone structure and are pumped and discharged.
Specifically, refined brine in the reaction barrel enters the first refined brine barrel through the feed inlet, refined brine clear liquid is generated in the first refined brine barrel, and the liquid level of the refined brine clear liquid is above the feed inlet. The smart steamed clear liquid of production is gone into in the smart steamed bucket of second through discharge gate and communicating pipe by the pump, the smart steamed bucket of second filters the sediment once more, because the discharge gate height of first smart steamed bucket is higher, can not inhale the smart steamed bucket of second with the precipitate, consequently, the smart steamed clear liquid that gets into the smart steamed bucket of second deposits the back once more in the smart steamed bucket of second, its precipitate is few almost, the scale deposit is few, very easily get rid of, consequently, the smart steamed bucket of second still adopts flat structure in the past, and the feed inlet and the discharge gate position of the smart steamed bucket of second also need not to improve, greatly reduced cost. And (3) the refined brine clear liquid after being filtered and clarified in the second refined brine barrel enters a third refined brine barrel to finally obtain clean refined brine clear liquid, and then the obtained refined brine clear liquid is conveyed to salt making equipment to enter a salt making process. In addition, the sediment collected by the cone at the lower part of the first refined brine barrel is automatically pumped and drained by the pumping and draining device every two days.
It is understood that the present invention may also be used with only two fine-marinating drums, for example, with the second drum eliminated, and still obtain a higher quality clear fine-marinated liquor.
In conclusion, the invention greatly reduces the SS content in the refined brine and improves the quality of the refined brine by the cone design of the refined brine barrel, the improvement of the feed inlet and the discharge outlet and the combination of the pumping device for discharging the mud, thereby ensuring the product quality and reducing the energy consumption cost of manual mud cleaning and salt making.
