At this time, the equipment controls the drive motor to start, so that the angle between the stirring plate and the horizontal plane increases but does not exceed 60°. When the angle between the stirring plate and the horizontal plane increases, the stirring effect of the stirring plate on the liquid raw material in the storage tank is enhanced as the rotating rod rotates, so that the viscous liquid raw material can be better mixed and heated.

[0018] 3. By setting components such as stirring plates, pressure sensors and rotating rods, as the filling proceeds, the liquid level of the raw materials in the storage tank gradually decreases.

[0022] In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0023] Polyurethane foam sealant needs to be seasoned before production. During the seasoning process, the purchased chlorinated paraffin and polyether polyol liquid raw materials are stored in storage tanks, and the purchased barreled silicone oil (silicone surfactant) and catalyst (dimorpholino diethyl ether) are temporarily stored in the seasoning workshop. When mixed, the metering ratio is automatically controlled by the pipeline with valves connecting the storage tank, plastic barrel and automatic control metering hopper. The ingredients are pumped from the storage tank and plastic barrel into the controlled metering hopper respectively, and the entire feed pipeline and the controlled metering hopper are kept closed.

[0024] The liquid raw materials polyether polyol and chlorinated paraffin mixed in the controlled hopper enter the seasoning kettle equipped with a heating rod at the bottom through a closed pipe and a control valve (the heat source is provided by the heat-conducting oil after electrical heating through the pipe at the bottom of the tank, and the heating temperature does not exceed 40°C. The purpose of heating is to make the viscosity of the liquid raw materials thinner without affecting their physical and chemical properties) for pre-mixing. At the same time, the liquid raw materials silicone oil (organic silicon surfactant) and catalyst (bismorpholinyl diethyl ether) mixed in the controlled hopper enter the seasoning kettle equipped with a heating rod at the bottom through a closed pipe and a control valve. (The heat source is provided by the electrically heated heat transfer oil through the pipeline at the bottom of the tank, and the heating temperature does not exceed 40°C. The purpose of heating is to thin the viscosity of the liquid raw materials without affecting their physical and chemical properties) for pre-mixing, and then the two groups of pre-mixed raw materials are pumped into the white material storage tank with a heating rod at the bottom through the unloading pipeline at the bottom of the seasoning kettle and the control valve (the heat source is provided by the electrically heated heat transfer oil through the pipeline at the bottom of the tank, and the heating temperature does not exceed 40°C. The purpose of heating is to thin the viscosity of the liquid raw materials without affecting their physical and chemical properties), and then filled after mixing evenly.

[0025] During the process of discharging the liquid raw material in the storage tank 1 for filling, as the liquid raw material in the storage tank 1 is discharged, the raw material will adhere to the inner wall of the storage tank 1, and the adhered raw material will affect the ratio of the next raw material, affecting the effect of polyurethane foam production, and when heating through the oil guide pipe 301 at the bottom of the tank body, it is difficult to uniformly heat the raw material in the storage tank 1, and after the liquid raw material in the storage tank 1 is discharged, the liquid raw material will adhere to the oil guide pipe 301 and the stirring plate 404. Therefore, the following solution is proposed: like Figures 1 to 6 As shown, the filling and storage equipment of the present invention comprises a storage tank 1 and a filling component 2, a heating component 3 is arranged in the storage tank 1, a stirring component 4 is arranged on the top of the heating component 3 in the storage tank 1, and a scraping component 5 is also arranged on the inner wall of the storage tank 1, the storage tank 1 is used to store liquid raw materials, and the filling component 2 is used to fill the liquid raw materials, the heating component 3 is used to heat the liquid raw materials in the storage tank 1, and the heating temperature does not exceed 40°C, the stirring component 4 is used to stir and mix the liquid raw materials in the storage tank 1 so that the liquid raw materials can be evenly mixed and heated, and the scraping component 5 can scrape off the liquid raw materials adhered to the inner wall of the storage tank 1 to prevent the residual liquid raw materials from affecting the subsequent production.

[0026] The heating component 3 includes an oil guide pipe 301, on which a scraper ring 302 is slidably arranged. A micro hydraulic cylinder 303 is arranged on the inner wall of the storage tank 1 on both sides of the oil guide pipe 301. The output end of the micro hydraulic cylinder 303 is connected to the scraper ring 302. The electrically heated heat-conducting oil will pass through the oil guide pipe 301, so that the oil guide pipe 301 can heat the liquid raw material in the storage tank 1. After the liquid raw material in the storage tank 1 is discharged, the micro hydraulic cylinder 303 is started, and the output end of the micro hydraulic cylinder 303 will drive the scraper ring 302 to move along the oil guide pipe 301. The movement of the scraper ring 302 will scrape off the liquid raw material adhered to the oil guide pipe 301.

[0027] The stirring assembly 4 includes a rotating rod 401, a cavity 402 is provided in the middle of the rotating rod 401, a connecting shaft 403 is rotatably provided on the rotating rod 401, a stirring plate 404 is provided on the connecting shaft 403, a driving assembly is provided in the cavity 402, the driving assembly includes a driving motor 405, the driving motor 405 is provided in the cavity 402, a first bevel gear 406 is provided at the output end of the driving motor 405, a second bevel gear 407 is provided on one side of the connecting shaft 403 located in the cavity 402, the first bevel gear 406 and the second bevel gear 407 are meshed for transmission, and when the rotating rod 401 rotates, the connecting shaft 403 is used to drive the stirring plate 404. With the assistance of , the stirring plate 404 can rotate. The rotation of the stirring plate 404 can stir the liquid raw materials in the storage tank 1, so that the liquid raw materials in the storage tank 1 are evenly mixed. After starting the driving motor 405, the output end of the driving motor 405 will drive the rotation of the first bevel gear 406. The rotation of the first bevel gear 406 drives the rotation of the second bevel gear 407 through meshing transmission. The rotation of the second bevel gear 407 drives the rotation of the connecting shaft 403, thereby changing the inclination angle of the stirring plate 404. When the inclination angle of the stirring plate 404 changes, the stirring effect of the stirring plate 404 will also change accordingly.

[0028] A rotating motor 7 is arranged on the top of the storage tank 1, and the output end of the rotating motor 7 is connected to the rotating rod 401. A feeding pipe 8 is arranged on the upper side of the storage tank 1. When the rotating motor 7 is started, the output end of the rotating motor 7 will drive the rotation of the rotating rod 401. The rotating motor 7 provides power for the rotation of the rotating rod 401, so that the rotation of the rotating rod 401 is stable and controllable, and the liquid raw material can be assisted by the feeding pipe 8. Input into the storage tank 1.

[0029] The two sides of the stirring plate 404 are arc-shaped, and pressure sensors are provided on the arc-shaped surfaces on both sides of the stirring plate 404. When the stirring plate 404 rotates with the rotating rod 401, the liquid raw material in the storage tank 1 will generate pressure on the pressure sensor at the side end of the stirring plate 404, thereby increasing the detection value of the pressure sensor. The thicker the liquid raw material, the larger the corresponding detection value of the pressure sensor will be. In addition, when the inclination angle of the stirring plate 404 changes, since the two sides of the stirring plate 404 are arc-shaped, and the pressure sensor is also arc-shaped and fits on the side of the stirring plate 404, the change in the inclination angle of the stirring plate 404 will not have too much impact on the detection value of the pressure sensor.

[0030] The scraper assembly 5 includes a limiting ring 501. The inner wall of the storage tank 1 is provided with an annular groove. The limiting ring 501 rotates in the annular groove. A scraper plate 502 is provided on the limiting ring 501. A transmission rod 503 is provided inside the limiting ring 501. When the limiting ring 501 rotates in the annular groove, the limiting ring 501 drives the scraper plate 502 to move. The transmission rod 503 is elastic. The scraper plate 502 is attached to the inner wall of the storage tank 1. The stirring plate 404 moves with the rotating rod 401. During the rotation process, when the stirring plate 404 is deflected to an angle of 60° with the horizontal plane, it will contact the transmission rod 503. The movement of the scraper plate 502 will scrape off the liquid raw material adhering to the inner wall of the storage tank 1, and when the angle between the stirring plate 404 and the horizontal plane is greater than or equal to 60°, when the stirring plate 404 rotates with the rotating rod 401 and passes through the transmission rod 503, the stirring plate 404 will push the transmission rod 503 to move, thereby causing the limit ring 501 to rotate.

[0031] The filling component 2 includes a first hydraulic cylinder 201, a support rod 202 is arranged on the top of the first hydraulic cylinder 201, a mounting plate 203 is arranged on the upper end of the support rod 202, a sleeve 204 is arranged on the top of the mounting plate 203, a three-way valve 205 is arranged at the lower end of the storage tank 1, the three-way valve 205 is connected with the sleeve 204, a hose 206 is also arranged at the side end of the three-way valve 205, and an adjusting component 6 is also arranged at the side end of the three-way valve 205. The three-way valve 205 is controlled by the adjusting component 6 to connect the storage tank 1 with the sleeve 204, or to connect the sleeve 204 with the hose 206.

[0032] A connecting rod 207 is provided at the output end of the first hydraulic cylinder 201, a piston plate is provided in the sleeve 204, the connecting rod 207 passes through the mounting plate 203 and is inserted into the sleeve 204, the upper end of the connecting rod 207 is connected to the piston plate, a filling head 208 is provided at the end of the hose 206, the upper end of the filling head 208 is provided with a second hydraulic cylinder 209, the output end of the second hydraulic cylinder 209 is connected to the filling head 208, the three-way valve 205 is controlled by the regulating component 6, so that the storage tank 1 is connected with the sleeve 204, when the first hydraulic cylinder 201 is started in the forward direction, the connecting rod 207 will move downward, and the downward movement of the connecting rod 207 cooperates with the piston plate in the sleeve 204 and the sleeve 204, so that the liquid raw material in the storage tank 1 is sucked into the sleeve 204, Then, the three-way valve 205 is controlled by adjusting the component 6 to connect the hose 206 with the sleeve 204, and the first hydraulic cylinder 201 is started in reverse, and the connecting rod 207 moves upward. The upward movement of the connecting rod 207 cooperates with the piston plate in the sleeve 204 and the sleeve 204, so that the liquid raw material in the sleeve 204 is pressed into the hose 206, and then the liquid raw material in the hose 206 is sprayed and filled through the filling head 208. By controlling the first hydraulic cylinder 201, the amount of each filling can be accurately controlled, and the second hydraulic cylinder 209 is often installed on the transportation line of the empty finished product cans. After the second hydraulic cylinder 209 is started, the filling head 208 will be lowered to fit the empty finished product cans, so that the filling head 208 can be better filled.

[0033] The adjustment component 6 includes a control rod 601, which is inserted into the three-way valve 205. The three-way valve 205 is provided with a mounting plate 602 on one side of the control rod 601. A transmission plate 603 is provided on the control rod 601. A third hydraulic cylinder 604 is rotatably provided at the lower end of the mounting plate 602. The output end of the third hydraulic cylinder 604 is rotatably connected to the transmission plate 603. When the third hydraulic cylinder 604 is started, the output end of the third hydraulic cylinder 604 will drive the deflection of the transmission plate 603. When the transmission plate 603 deflects, the control rod 601 will rotate. The rotation of the control rod 601 will control the three-way valve 205, so that the storage tank 1 is connected to the sleeve 204, or the sleeve 204 is connected to the hose 206.

[0034] During use of the present invention, two groups of premixed raw materials are pumped into the storage tank 1 through the feed pipe 8, and then the rotating motor 7 is started. The output end of the rotating motor 7 drives the rotation of the rotating rod 401. The rotation of the rotating rod 401 causes the stirring plate 404 to rotate with the assistance of the connecting shaft 403 (the angle between the stirring plate 404 and the horizontal plane is 30° in the initial state). As the stirring plate 404 rotates with the rotating rod 401, the stirring plate 404 will stir and mix the raw materials in the storage tank 1. At the same time, the electrically heated heat transfer oil will pass through the oil guide pipe 301, so that the oil guide pipe 301 can heat the liquid raw material in the storage tank 1, and as the stirring plate 404 stirs the liquid raw material, the liquid raw material can be heated more evenly.

[0035] When the stirring plate 404 starts to stir the liquid raw material, the liquid raw material will act on the pressure sensor. At this time, the detection value of the pressure sensor corresponds to the viscosity of the liquid raw material. As the heating and stirring continue, the detection value of the pressure sensor will gradually decrease.

[0036] When the stirring plate 404 just starts to stir the liquid raw material, the detection value of the pressure sensor will increase and exceed the threshold value, indicating that the viscosity of the liquid raw material in the storage tank 1 is large at this time. At this time, the device controls the drive motor 405 to start, and the output end of the drive motor 405 will drive the rotation of the first bevel gear 406. The rotation of the first bevel gear 406 drives the rotation of the second bevel gear 407 through meshing transmission. The rotation of the second bevel gear 407 will rotate the connecting shaft 403, thereby increasing the angle between the stirring plate 404 and the horizontal plane but not exceeding 60°. The difference between the detection value of the pressure sensor and the threshold value corresponds to the angle between the stirring plate 404 and the horizontal plane. When the angle between the stirring plate 404 and the horizontal plane increases, the stirring effect of the stirring plate 404 on the liquid raw material in the storage tank 1 is enhanced as the rotating rod 401 rotates, so that the viscous liquid raw material can be better mixed and heated.

[0037] As stirring and heating proceed, the viscosity of the liquid raw material in the storage tank 1 will decrease, making the liquid raw material thinner, so the detection value of the pressure sensor will gradually decrease. When the detection value of the pressure sensor decreases to less than the threshold value, it indicates that the liquid raw material in the storage tank 1 has reached the filling requirement. At this time, the equipment controls the drive motor 405 to reverse, thereby reducing the angle between the stirring plate 404 and the horizontal plane but greater than 0°, thereby weakening the stirring effect of the stirring plate 404. On the one hand, it ensures that the liquid raw material in the storage tank 1 remains in a flowing state, and on the other hand, it avoids excessive stirring that makes the liquid raw material in the storage tank 1 low in the middle and high around, thereby avoiding an increase in the adhesion area of ​​the liquid raw material on the inner wall of the storage tank 1.

[0038] When the detection value of the pressure sensor is less than the threshold value, the third hydraulic cylinder 604 is started to deflect the transmission plate 603, thereby rotating the control rod 601. The rotation of the control rod 601 controls the three-way valve 205 to connect the sleeve 204 with the storage tank 1, and then the first hydraulic cylinder 201 is started to move the connecting rod 207 downward. The downward movement of the connecting rod 207 cooperates with the piston plate to draw the liquid raw material in the storage tank 1 into the sleeve 204, and then the three-way valve 205 is controlled again by controlling the third hydraulic cylinder 604 to connect the sleeve 204 with the hose 206. At the same time, the second hydraulic cylinder 209 is started to fit the filling head 208 with the tank mouth of the finished product tank, and then the first hydraulic cylinder 201 is reversed to move the connecting rod 207 upward, so that the liquid raw material in the sleeve 204 is pressed into the hose 206, and the filling head 208 fills the raw material into the finished product tank.

[0039] As the filling proceeds, the raw material liquid level in the storage tank 1 gradually decreases. When the liquid level drops below the stirring plate 404, the detection value of the pressure sensor at the side end of the stirring plate 404 will decrease to 0. At this time, the equipment controls the drive motor 405 to start, so that the inclination angle of the stirring plate 404 increases to more than 60° but not more than 90°. At this time, as the stirring plate 404 rotates with the rotating rod 401, the stirring plate 404 will contact the transmission rod 503, so the stirring plate 404 will push the transmission rod 503 to move, so that the limit ring 501 rotates, and the rotation of the limit ring 501 will move the scraper plate 502. The movement of the scraper plate 502 will scrape the raw material on the inner wall of the storage tank 1, and the scraped raw material will fall to the bottom of the storage tank 1.

[0040] When the inclination angle of the stirring plate 404 just increases to more than 60°, the contact between the stirring plate 404 and the transmission rod 503 cannot push the transmission rod 503 to move. Since the transmission rod 503 is elastic, the transmission rod 503 will cross the stirring plate 404 when it contacts the stirring plate 404, causing the stirring plate 404 to vibrate. The vibration of the stirring plate 404 will cause the raw materials adhered to the stirring plate 404 to fall off, and since the stirring plate 404 rotates with the rotating rod 401, the raw materials adhered to the stirring plate 404 will gradually move toward the transmission rod 503 due to the influence of centrifugal force. When the transmission rod 503 crosses over the stirring plate 404, the transmission rod 503 can scrape off the raw materials at the end of the stirring plate 404. When the inclination angle of the stirring plate 404 increases to nearly 90°, the stirring plate 404 can stably push the transmission rod 503 to move.

[0041] As the filling proceeds, when the raw materials in the storage tank 1 are lower than the stirring plate 404 at the lowest end, the detection values ​​of all the pressure sensors will drop to 0. At this time, the equipment controls the inclination angle of all the stirring plates 404 to be controlled at 60°, so that when the stirring plates 404 rotate with the rotating rod 401, the transmission rod 503 contacts the stirring plates 404 and crosses the stirring plates 404 due to the elastic effect, so that the stirring plates 404 and the transmission rod 503 vibrate, and the oil guide pipe 301 also vibrates slightly through the vibration transmission, and at the same time, the micro hydraulic cylinder 303 is started to reciprocate for a set time, so that the scraper ring 302 reciprocates. The reciprocating operation of the scraper ring 302 will push and stir the raw materials near the oil guide pipe 301, and when the liquid level is lower than the oil guide pipe 301, the reciprocating movement of the scraper ring 302 and the slight vibration of the oil guide pipe 301 cooperate to clean up and drop the raw materials adhering to the surface of the oil guide pipe 301, so as to ensure that the raw materials can be fully used.

[0042] The main functions achieved by the present invention are: by setting components such as a stirring plate 404, a transmission rod 503, a pressure sensor and a scraper plate 502, the viscosity of the raw material in the storage tank 1 can be indirectly detected with the assistance of a pressure sensor, and a plurality of pressure sensors can cooperate to detect the liquid level of the raw material in the storage tank 1. When the liquid level drops below the stirring plate 404, the detection value of the pressure sensor on the stirring plate 404 drops to 0. At this time, by controlling the inclination angle of the stirring plate 404, the scraper plate 502 can clean the inner wall of the storage tank 1, and the stirring plate 404 will also be knocked by the transmission rod 503 to form vibration to clean the stirring plate 404. When all the pressure sensors drop to 0, by controlling the micro hydraulic cylinder 303, the scraper ring 302 moves back and forth to ensure that the raw material at the bottom of the storage tank 1 remains flowing, and the oil guide pipe 301 can be cleaned, so that the raw material in the storage tank 1 is fully utilized.

[0043] The present invention also provides an application of a filling and storage device in the production of a polyurethane foam sealant, and the filling and storage device is used to perform filling processing on raw materials for producing the polyurethane foam sealant.
