[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0017] like Figure 1-2As shown, an adjustable self-mixing tank includes a closed tank A and an electric ball valve 3, an oil supply pump 2, and a control cabinet 1 located outside the tank A. The tank A contains a softened water chamber 10 for storing clean water, an automatic liquid mixing device chamber 11 for installing liquid mixing equipment, an emulsified oil chamber 12 for storing emulsified oil, and an emulsified liquid chamber 13 for storing emulsion. The softened water chamber 10, the automatic liquid mixing device chamber 11, the emulsified oil chamber 12, and the emulsified liquid chamber 13 are separated by a sealing partition. An external water source is connected to the inlet of the electric ball valve 3 through an external water inlet pipe, and the outlet of the electric ball valve 3 is connected to the inlet of the softened water chamber 10 in the tank A. An external oil source is connected through a pipeline... The oil supply pump 2 is connected to the oil inlet. The oil outlet of the oil supply pump 2 is connected to the oil inlet of the emulsified oil chamber 12 of the housing A through an oil inlet pipe. The automatic liquid dispensing device chamber 11 of the housing A is equipped with a softened water pump 4, an emulsified oil pump 5 and a mixing agitator 8. The water inlet of the softened water pump 4 is connected to the water outlet of the softened water chamber 10 through a water pipe. The water outlet of the softened water pump 4 is connected to the mixing agitator 8 through a water pipe. The oil inlet of the emulsified oil pump 5 is connected to the oil outlet of the emulsified oil chamber 12 through an oil pipe. The oil outlet of the emulsified oil pump 5 is connected to the mixing agitator 8 through an oil pipe. The mixing agitator 8 is equipped with a concentration sensor 9. The outlet of the mixing agitator 8 is connected to the emulsified liquid chamber 13 through a liquid pipe.

[0018] The concentration sensor 9 is connected to the PLC controller in the control cabinet 1. The PLC controller in the control cabinet 1 is connected to the electric ball valve 3, the oil supply pump 2, the softened water pump 4, the emulsified oil pump 5, and the mixing agitator 8. The PLC controller is also connected to the PLC main control panel.

[0019] In this embodiment, a liquid level sensor 7 is provided in each of the softened water chamber 10, the emulsified oil chamber 12 and the emulsified liquid chamber 13. The liquid level sensor 7 is connected to the control cabinet 1.

[0020] In this embodiment, the oil supply pump 2 is a remote oil supply pump 2, the softened water pump 4 is a horizontal centrifugal pump, and the emulsified oil pump 5 is a gear pump.

[0021] In this embodiment, a one-way valve 6 is installed on the water pipe. Alternatively, a one-way valve 6 can be installed on the oil pipe as needed.

[0022] In this embodiment, a power supply is also included. The electric ball valve 3, oil supply pump 2, centrifugal pump, gear pump, mixing agitator 8, concentration sensor 9, liquid level sensor 7 and control cabinet 1 are all connected to the power supply.

[0023] In this embodiment, control cabinet 1 is used to control the start and stop of the equipment and has functions such as automatic liquid preparation and low liquid level protection. Automatic water and oil inlet and liquid preparation are controlled via an explosion-proof intrinsically safe PLC main control panel. The emulsion concentration, liquid level, and oil level are all integrated and displayed on the main control cabinet 1 display panel, and users can modify these parameters as needed. A remote oil supply pump is used to deliver emulsified oil to the emulsified oil chamber 12. The electric ball valve 3 is controlled via the PLC main control panel; that is, by operating the PLC main control panel, a signal is sent to the PLC controller, which controls the electric ball valve 3 to start and close, and to start and stop the water inlet of the softened water chamber 10 as required. A horizontal centrifugal pump is used to draw clean water and send it to the mixing agitator 8. A gear pump is used to draw emulsified oil and send it to the mixing agitator 8. A one-way valve 6 prevents liquid backflow. Liquid level sensor 7 is used to measure the liquid level in the softened water chamber 10, emulsified oil chamber 12, and emulsion chamber 13 in real time, and displays the liquid level value on the PLC main control panel of control cabinet 1 in real time via a data cable. Mixing agitator 8 is used to mix a certain proportion of softened water and emulsified oil to prepare an emulsion of a certain concentration. Concentration sensor 9 is used to monitor the concentration of the emulsion and upload the data in real time.

[0024] This embodiment of the adjustable self-mixing tank enables automatic mixing of emulsions to the required concentration and can automatically start and stop the tank based on the real-time liquid level. It features low liquid level, low oil level, emulsion concentration display, and fault diagnosis functions, and also supports online circulating monitoring and data uploading of the concentration. The tank A adopts a closed layout, effectively preventing dust and impurities from entering the tank and ensuring the cleanliness of the internal liquid. Sufficient internal steel supports ensure the strength of the entire tank A. Tank A is made of stainless steel, possessing high corrosion resistance and oxidation resistance, and has a stable support at the bottom for easy transportation. The adjustable self-mixing tank consists of five main parts: a softened water chamber 10, an automatic mixing device chamber 11, an emulsion oil chamber 12, an emulsion chamber 13, and a control cabinet 1. It is mainly used for automatically mixing emulsions of the required concentration for use with downhole hydraulic supports and other hydraulic equipment. Softened water and emulsified oil are transported by centrifugal pump and gear pump in automatic liquid preparation device chamber 11 to the liquid preparation device (i.e., mixing agitator 8) for mixing to complete the preparation.

[0025] The adjustable mixing tank can be paired with a remote oil supply pump 2 and a downhole online integrated reverse osmosis water treatment system to achieve automatic water replenishment, automatic oil addition, automatic emulsion preparation, and automatic delivery. It meets the needs of unattended operation, including remote command, one-button start / stop, automatic operation, automatic troubleshooting, and emergency shutdown.

[0026] Working principle: When the self-mixing tank is working, the electric ball valve 3, oil supply pump 2, softened water pump 4, emulsified oil pump 5 and mixing agitator 8 are controlled by the PLC controller. First, the electric ball valve 3 is opened to deliver clean water from the external water source to the softened water chamber 10. At the same time, the remote oil supply pump 2 is also started to deliver emulsified oil from the external oil source to the emulsified oil chamber 12. The softened water pump 4 and the emulsified oil pump 5 draw softened water and emulsified oil from the softened water chamber 10 and the emulsified oil chamber 12 respectively and send them to the mixing agitator 8. The mixing agitator 8 mixes a certain proportion of softened water and emulsified oil to prepare an emulsion of a certain concentration. Simultaneously, the prepared emulsion is monitored by a concentration sensor 9 within the mixing agitator 8 (the mixing agitator 8 is elongated and includes an inlet section, a mixing section, and an outlet section; both softened water and emulsified oil enter the mixing section through the inlet section, where an electric stirring mechanism is installed to agitate them, ensuring uniform mixing. The emulsion then flows into the outlet section under the pressure of the liquid behind it, where the concentration sensor 9 detects the emulsion concentration). The concentration is then sent to the PLC controller. When the concentration is lower than the set value, the PLC controller controls the emulsified oil pump 5, increasing its operating power and thus increasing the emulsion concentration. When the monitored concentration is higher than the set value, the PLC controller reduces the operating power of the emulsified oil pump 5, decreasing the emulsion concentration. The emulsion, after being agitated by the mixing agitator 8, then enters the emulsion chamber 13 through a liquid pipe. The emulsion chamber 13 is equipped with a drain outlet and a liquid outlet. The liquid level sensor 7 in the emulsion chamber 13 continuously monitors the liquid level. When the liquid level is below the set lower limit, the softening water pump 4 and the emulsion oil pump 5 are started to automatically dispense the liquid. When the liquid level is above the set upper limit, the softening water pump 4 and the emulsion oil pump 5 are stopped. The parameters can also be adjusted manually using the PLC main control panel on the control cabinet 1, providing both automatic and manual control modes. Liquid level sensors 7 are also installed in the softened water chamber 10 and the emulsified oil chamber 12. These sensors monitor the water and oil levels in real time. When the water level in the softened water chamber 10 is lower than the set lower limit, the PLC controller controls the electric ball valve 3 to open, allowing clean water to enter the softened water chamber 10 until the water level reaches the set upper limit. Similarly, when the oil level in the emulsified oil chamber 12 is lower than the set lower limit, the PLC controller controls the remote oil supply pump 2 to open, allowing oil to enter the emulsified oil chamber 12 until the oil level reaches the set upper limit. The external water source can be water treated by the downhole online integrated reverse osmosis water treatment system. The external oil source can also be an external oil tank. The control cabinet 1 is also equipped with a display screen connected to the PLC controller, used to display the emulsion concentration, water level information detected by the level sensor 7, oil level information, and liquid level information. The PLC controller on the control cabinet 1 is remotely connected to a server, allowing data to be uploaded to the server.In this embodiment, the PLC controller, electric ball valve 3, oil supply pump 2, softened water pump 4, emulsified oil pump 5, and mixing agitator 8 all adopt existing structures.
