Description

Technical Field

[0001] The utility model relates to the technical field of brine mining devices, in particular to a brine well anti-blocking mechanism. Background Art

[0002] Mine salt, also known as "well salt", "well mine salt" or "underground salt", is a type of salt extracted from underground salt mines. It generally refers to salt made by drilling and extracting underground natural brine and salt made by mining underground rock salt. In the mid-1950s, the hydraulic fracturing technology of oil fields was introduced to the mining of rock salt, that is, the solution cavity was connected through hydraulic fracturing, one well was injected with water, and another well or multiple wells produced brine to form a well group production, and gradually developed in the direction of automation.

[0003] When the brine is mined in a brine well, the temperature of the brine will drop as it returns to the surface. Substances such as sodium chloride in the brine will be partially oversaturated and form crystals, which can easily block the brine outlet channel. Back-injection of water is required to dissolve the crystals in time to prevent well blockage. However, the brine concentration is low for a period of time after the brine is returned after back-injection, which affects the stability and production capacity of brine mining and subsequent production.

[0004] Therefore, the above-mentioned brine wells are prone to crystallization and blockage of the brine outlet channel due to the drop in brine temperature, and the problem of producing a large amount of light brine after back injection needs to be solved urgently to improve the continuous and stable production capacity of the brine wells. Utility Model Content

When the water injection pipe is injecting water to dissolve brine crystals, the brine concentration after injection can be detected in real time by the salinometer, so that the water release speed of the solenoid valve can be controlled by the valve controller to adjust the water injection amount at any time, thereby preventing the brine well from being blocked and reducing the amount of light brine as much as possible.

[0010] Preferably, a positioning hole is provided on the upper side of the limit groove, the temperature and humidity sensor is located at the upper end of the brine outlet pipe, and the bottom passes through a fixing hole and a positioning hole. The temperature and humidity sensor can be fixed through the fixing hole, and the temperature inside the brine outlet pipe can be monitored through the temperature and humidity sensor, and the detection data can be sent to the valve controller, so that the valve controller can control the solenoid valve to adjust the water injection amount at different temperatures.

[0011] Preferably, a filter hole is opened inside the lower end of the brine outlet pipe at a position corresponding to the mounting groove, the water pump is located inside the filter hole, and the upper end passes through the mounting groove. Impurities in the brine can be filtered through the filter hole, thereby improving the accuracy of the salinity meter in measuring the brine concentration.

[0013] Preferably, a solenoid valve is installed on the outside of the threaded joint, and a valve controller is arranged on the top of the solenoid valve. The threaded joint can be convenient for connecting a water pipe, and the valve controller can be used to receive detection data from a temperature and humidity sensor and a salinity meter. The detection data can be used to control the solenoid valve to adjust the water injection volume in a targeted manner.
