[0024] A liquid level monitoring device for preparing nitrile butadiene raw materials includes: a storage tank 1 and a liquid storage section 11. A support base 2 is provided at the lower part of the storage tank 1. A discharge pipe 3 is connected to the bottom of the storage tank 1 through the support base 2. A discharge valve 4 is provided on the discharge pipe 3. An insulation layer 5 and a control panel are provided on the outside of the storage tank 1 to maintain a stable material temperature inside the storage tank 1. A top cover 6 is provided at the top of the storage tank 1. A stirring assembly 7 is provided on the top cover 6 to prevent material from settling after prolonged standing. A trigger assembly 8 is provided on the inside of the top cover 6. A bracket 9 is fixedly connected to the upper part of the top cover 6. A control switch 10 is provided below the bracket 9 and is electrically connected to the liquid storage section 11.

[0025] During operation, changes in the liquid level inside storage tank 1 cause the trigger component 8 to perform mechanical linkage, and the control switch 10 controls the replenishment circulation. The stirring and scraping process of the stirring component 7 maintains the stability and uniformity of the material inside storage tank 1.

[0026] The stirring assembly 7 includes a drive motor 71, the output end of which is connected to a drive shaft 72. Two fixing members 73 are fixedly connected to the drive shaft 72. The fixing plates on both sides of the fixing members 73 are connected to stirring fans 74 for stirring the material at the bottom of the storage tank 1.

[0027] The stirring assembly 7 drives the stirring fan 74 to rotate via the drive motor 71, which can evenly mix the materials in the tank, prevent high-viscosity liquids or suspensions from settling or stratifying, and ensure the homogeneity of the raw materials.

[0028] A scraper 75 is fixedly connected to the outer side of the stirring fan 74. The outer side of the scraper 75 is made of soft material and is close to the inner wall of the storage tank 1.

[0029] A scraper 75 is fixedly connected to the outside of the stirring fan 74. The scraper 75 is made of soft material and is close to the inner wall of the storage tank 1. It can scrape off the residual material adhering to the inner wall during the stirring process and reduce scaling.

[0030] The triggering component 8 includes a first rotating seat 81, a first connecting rod 82 rotatably connected to the first rotating seat 81, a detection float 83 fixedly connected to the end of the first connecting rod 82, a second rotating seat 84 fixedly connected to the first connecting rod 82, a sliding rod 85 rotatably connected to the second rotating seat 84, a sleeve 86 slidably connected to the sliding rod 85, a spring 87 fixedly connected inside the sleeve 86, the other end of the spring 87 fixedly connected to the sliding rod 85, a third rotating seat 88 fixedly connected to the upper end of the sleeve 86, a lifting rod 89 rotatably connected to the third rotating seat 88, the lifting rod 89 slidably connected to the top cover 6, and the lifting rod 89 is located directly below the control switch 10, controlling the corresponding operation of the liquid storage section 11 according to the liquid level.

[0031] The inner side of the top cover 6 is provided with a trigger component 8. By detecting the rise and fall of the float 83 with the liquid level, the sliding rod 85 and the lifting rod 89 are driven to move, so that the lifting rod 89 moves upward in linkage, triggering the control switch 10, realizing the automatic replenishment or stopping of feeding of the liquid storage section 11 triggered by the high or low liquid level threshold, avoiding the risk of overflow or empty tank.

[0032] The liquid storage section 11 includes a liquid storage tank 111. A delivery pump 112 is provided on the upper part of the liquid storage tank 111. An inlet pipe 113 and a return pipe 115 are connected to the delivery pump 112.

[0033] The liquid storage tank 111 of the liquid storage section 11 realizes the circulation or replenishment of raw materials through the delivery pump 112, the inlet pipe 113 and the return pipe 115. The first control valve 114 and the second control valve 116 can adjust the feed and return flow rates respectively to ensure the replenishment accuracy. The return pipe 115 cooperates with the second control valve 116 to guide the excess material back to the liquid storage tank 111 when the delivery pump 112 supplies too much liquid, thereby reducing energy waste and maintaining system pressure balance, while reducing equipment wear caused by frequent pump start-stop.

[0034] The top cover 6 is equipped with an exhaust pipe 12, and the exhaust pipe 12 is equipped with a safety valve 13 to ensure the safety of raw material storage.

[0035] The exhaust pipe 12 and safety valve 13 installed on the top cover 6 can automatically release pressure when the pressure inside the tank is abnormal, preventing overpressure explosion caused by the accumulation of volatile raw material vapors. At the same time, the exhaust gas can be purified by connecting to an external treatment device, which meets environmental protection requirements.

[0036] The working principle of the liquid level monitoring device for preparing nitrile butadiene raw materials provided by this utility model is as follows:

[0037] During operation, changes in the liquid level inside storage tank 1 cause the trigger component 8 to perform mechanical linkage, and the control switch 10 controls the replenishment circulation. The stirring and scraping process of the stirring component 7 maintains the stability and uniformity of the material inside storage tank 1.

[0038] Compared with related technologies, the liquid level monitoring device for preparing nitrile butadiene raw materials provided by this utility model has the following beneficial effects:

[0039] The device mixes materials and removes residues from the tank wall through the stirring fan 74 and scraper 75 of the stirring assembly 7, triggering the float ball 83 of the assembly 8 to control the switch 10, thereby realizing liquid level monitoring and automatic replenishment of the storage section 11 or return of overflowing materials. The delivery pump 112, together with two control valves, regulates the flow rate and stabilizes the pressure of the return flow. Combined with the exhaust pipe 12 and the safety valve 13, it relieves pressure and prevents explosion, ensuring the homogeneity of raw materials, controllable liquid level and safe storage.
