Description

Technical Field

[0001] This utility model belongs to the field of cement storage technology, and more specifically, it relates to a multi-functional cement storage tank that prevents solidification. Background Technology

[0002] Cement will gradually solidify after prolonged exposure to air and standing still. Therefore, when storing cement, stirring is used to continuously turn the cement to prevent it from solidifying. In addition, appropriate pipelines should be installed outside the storage tank to output or input cement.

[0003] Based on the above, the storage tanks currently in use only provide a sealing and containment effect, making it inconvenient to adjust the internal pressure, remove internal air to prevent cement from hardening, and monitor the total amount of cement. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a multi-functional cement storage tank designed to prevent solidification. This solves the problem mentioned in the background art that existing storage tanks only provide a sealing and containment effect, making it inconvenient to adjust the internal pressure, remove internal air to prevent cement solidification, and monitor the total amount of cement.

[0005] The purpose and function of this utility model, a multi-functional cement storage tank designed to prevent solidification, are achieved through the following specific technical means:

[0006] A multi-functional cement storage tank with anti-solidification features a tank body. A transmission chamber is fixedly mounted in the middle of the top of the tank body, and a stirring motor is fixedly mounted on the top of the transmission chamber. A stirring shaft is rotatably mounted in the middle of the tank body, and the top of the stirring shaft is connected to the stirring motor. A pressure sensor, valve A, and a one-way valve are fixedly mounted on the top of the tank body. A convex chamber is sealed on the top of the tank body, and a telescopic rod is fixedly mounted at the bottom of the convex chamber. A floating valve, which has a spherical structure, is fixedly mounted at the bottom of the telescopic rod and can slide into the convex chamber. A pressure sensor is fixedly mounted on one side of the tank body. A delivery pump is fixedly mounted on one side of the tank body, and three-way valves are respectively installed at both ends of the delivery pump, connecting valves D, E, F, and G. Pipes are connected to valves E and G and lead to the tank body.

[0007] Furthermore, an air pump is connected to the top of valve A, and the other end of the air pump is connected to an inert gas source; the other end of the one-way valve is connected to a water source.

[0008] Furthermore, a three-way connection is provided at the top of the convex chamber to connect valve B and valve C; a filter screen is provided outside valve B; and the other end of valve C is connected to an exhaust pipe.

[0009] Furthermore, the stirring shaft is integrally provided with two rows of arc-shaped stirring rods, the cross-section of which is inclined, and the outer end of which is fixedly provided with a scraping strip.

[0010] Furthermore, a slide cylinder is fixedly installed on the top of the floating valve, and the slide cylinder slides in the tee at the top of the convex compartment; an air hole is opened on the outer side of the bottom of the slide cylinder; and an interception cover is fixedly installed on the top edge of the floating valve.

[0011] Furthermore, a pressure sensor is fixedly installed outside the pressure sensor, and a piston block is fixedly installed at the detection end of the pressure sensor, with the piston block sliding inside the pressure sensor.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By inputting and discharging cement, and in conjunction with valve B, the internal air pressure of the tank can be naturally regulated. The air pump is started to input inert gas into the tank, compressing and outputting the air. The air is discharged to a designated location through the exhaust pipe, ensuring that there is no nitrogen-oxygen-containing air in the tank. Utilizing the principle that inert gas does not react with cement, the state of the cement can be maintained. The mixing motor drives the mixing shaft to rotate, which can continuously mix the cement and prevent it from solidifying.

[0014] A pressure sensor can be installed to monitor cement pressure. The cement can exert pressure on the piston block. By placing the piston block close to the pressure sensor, the pressure can be continuously fed back, thereby detecting the total amount of cement and facilitating pressure sensing.

[0015] The curved stirring rod is designed to facilitate mixing of cement. The cross-section of the curved stirring rod is inclined, which can lift the cement during rotation. A scraper is fixed to the outer end of the curved stirring rod. The scraper can rotate close to the inside of the tank to reduce dead zones in cement mixing. Attached Figure Description

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0025] Example 1:

[0026] As attached Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides a multi-functional cement storage tank with anti-solidification function, including a tank body 1. A transmission chamber 101 is fixedly installed in the middle of the top of the tank body 1, and a stirring motor 102 is fixedly installed on the top of the transmission chamber 101. A stirring shaft 2 is rotatably installed in the middle of the tank body 1, and the top of the stirring shaft 2 is connected to the stirring motor 102. A pressure sensor 103, a valve A104, and a one-way valve 106 are fixedly installed on the top of the tank body 1. A convex chamber 107 is sealed on the top of the tank body 1. A telescopic end rod 3 is fixedly installed at the bottom of the convex chamber 107, and a floating valve 4 is fixedly installed at the bottom of the telescopic end rod 3. The floating valve 4 has a spherical structure and can slide into the convex chamber 107. A pressure sensor 5 is fixedly installed on one side of the tank body 1. A delivery pump 6 is fixedly installed on one side of the tank body 1. A three-way valve D7, valve E8, valve F9, and valve G10 are respectively installed at both ends of the delivery pump 6. Pipes are provided on the outside of valve E8 and valve G10 to connect to the tank body 1.

[0028] Among them, the top of valve A104 is connected to air pump 105, and the other end of air pump 105 is connected to an inert gas source. The inert gas can be any suitable type of gas that does not react with cement; the other end of one-way valve 106 is connected to a water source.

[0029] The top of the convex chamber 107 is equipped with a three-way connection to valves B108 and C109; a filter screen is installed outside valve B108; and the other end of valve C109 is connected to an exhaust pipe.

[0030] Among them, two rows of arc-shaped stirring rods 201 are integrally arranged outside the stirring shaft 2. The cross section of the arc-shaped stirring rods 201 is inclined, and the outer end of the arc-shaped stirring rods 201 is fixedly provided with scraper strips 202.

[0031] The top of the floating valve 4 is fixedly equipped with a slide cylinder 401, which slides in the top tee of the convex compartment 107; an air hole 402 is opened on the outer side of the bottom of the slide cylinder 401; an interceptor cover 403 is fixedly installed on the top edge of the floating valve 4; if the water is filled too much, the floating valve 4 can float up naturally to seal the tank 1 and prevent water or cement from flowing out.

[0032] The pressure sensor 501 is fixedly installed on the outside of the pressure sensor 5, and a piston block 502 is fixedly installed at the detection end of the pressure sensor 501. The piston block 502 slides in the pressure sensor 5. The pressure sensor 5 can monitor the pressure. Cement can exert pressure on the piston block 502. The piston block 502 is placed close to the pressure sensor 501 to continuously feed back the pressure, thereby detecting the total amount of cement.

[0033] like Figure 1-6 As shown, connect valve D7 to the cement manufacturing equipment, open valves D7 and G10, close valves E8 and F9, and start the delivery pump 6 to input cement into tank 1;

[0034] By opening valve B108, the air inside tank 1 can be squeezed out by increasing the filling volume;

[0035] After filling to the specified amount, turn off the delivery pump 6, valve D7 and valve G10, then open valve C109 and valve A104, close valve B108, start the air pump 105 to input inert gas into tank 1, compress the air and output it, and the air is discharged to the specified location through the exhaust pipe.

[0036] Inert gas does not react with cement. The tank 1 is filled with inert gas, which can maintain the state of the cement. The stirring motor 102 drives the stirring shaft 2 to rotate, which can continuously stir the cement and prevent it from solidifying. The pressure sensor 103 can help monitor whether the pressure is normal.

[0037] Example 2:

[0038] Based on Example 1, valves A104, B108, C109, D7, E8, F9, and G10 can all be selected according to their type and model. They can be controlled by a solenoid valve for centralized control or by a butterfly valve or gate valve for manual control to control the flow direction. The internal air pressure of tank 1 can be naturally adjusted by opening and closing the corresponding valves.

[0039] The specific usage and function of this embodiment are as follows:

[0040] In this utility model, when in use, valve D7 is connected to the cement manufacturing equipment, valves D7 and G10 are opened, valves E8 and F9 are closed, and the conveying pump 6 is started to input cement into tank 1; during this process, valve B108 is opened, and the air in tank 1 is squeezed out by increasing the filling volume.

[0041] After filling to the specified amount, turn off the delivery pump 6, valve D7, and valve G10. Then open valves C109 and A104, close valve B108, and start the air pump 105 to introduce inert gas into the tank 1, compressing and outputting the air. The air is discharged to the designated location through the exhaust pipe. At this time, there is no nitrogen-oxygen air in the tank 1, and the inert gas does not react with the cement, thus maintaining the state of the cement. The stirring motor 102 drives the stirring shaft 2 to rotate, continuously stirring the cement and preventing it from solidifying. The air pressure sensor 103 can help monitor whether the air pressure is normal.

[0042] Pressure can be monitored using pressure sensor 5. Cement can exert pressure on piston block 502. By placing piston block 502 close to pressure sensor 501, pressure is continuously fed back, thereby detecting the total amount of cement.

[0043] The one-way valve 106 is connected to a water source and can be replenished with tap water or other water sources controlled by the pump at regular intervals.

[0044] When cement needs to be discharged, connect valve F9 to the discharge point, open valves E8 and F9, keep valves D7 and G10 closed, and start the delivery pump 6 to output cement. During this period, the internal pressure of tank 1 drops, so valve A104 can be opened to continue to input inert gas to maintain the air pressure inside tank 1 and prevent the water in the cement from vaporizing under negative pressure.
