Description

Technical Field

[0001] The invention relates to the technical field of calcium-zinc composite stabilizers, in particular to an auxiliary material proportioning device for producing calcium-zinc composite stabilizers. Background Art

[0002] Calcium zinc stabilizers are generally divided into solid and liquid types. They are synthesized using a special composite process with calcium salts, zinc salts, lubricants, and antioxidants as the main components. They can not only replace toxic stabilizers such as lead-cadmium salts and organotin compounds, but also exhibit excellent thermal stability, light stability, transparency, and tinting strength.

[0003] The auxiliary material proportioning device used in the production of traditional calcium-zinc composite stabilizers is mainly composed of a storage bin, a volumetric metering mechanism, a conveying component and an ordinary stirring tank. During operation, the operator manually sets the metering parameters, and the volumetric metering mechanism conveys the auxiliary material according to the preset volume, which is sent into the stirring tank through the conveying component, and the stirring paddle rotates at a low speed for mixing.

[0004] However, the traditional device adopts volumetric metering. Due to changes in the moisture, density and other characteristics of the auxiliary materials, the weight deviation of the same volume of materials is large, the ratio is inaccurate, and there is a lack of precise temperature control system during mixing. Extensive heating or no temperature control can easily lead to overheating and decomposition of materials or insufficient reaction, affecting product quality. Equipment lubrication relies on manual labor, and there are problems such as untimely lubrication and difficult quantity control. Gears and other components wear out more, the risk of failure is high and maintenance costs increase, and it is difficult to adapt to continuous production. Traditional storage tanks are complicated to fix and difficult to disassemble. The inner wall and pipeline of the mixing tank are prone to residual materials. Manual cleaning is time-consuming and easy to contaminate subsequent batches. The lack of dust treatment in production not only endangers the health of operators and poses an explosion risk, but also faces environmental penalties for substandard emissions. In addition, traditional storage tanks are complicated to fix and difficult to disassemble. The inner wall and pipeline of the mixing tank are prone to residual materials. Manual cleaning is time-consuming and easy to contaminate subsequent batches. Summary of the Invention

[0032] Specifically, the storage tank 3 is fixed at the four corners of the support frame 2, specifically by aligning the flange base 41 with the mounting flange 42, then inserting the fixing bolts 43 and tightening the nuts 44 to complete the fixation. The electronic scale 6 inside the storage tank 3 weighs the auxiliary material in real time and transmits the data to the controller 22. The controller 22 controls the solenoid valve 8 on the connecting pipe 9 on the right side of the storage tank 3 to open according to the preset ratio parameters, and the auxiliary material falls into the mixing chamber 13 of the stirring tank 12 through the feeding port 7 through the feeding pipe 5. After the filling is completed, the sealing cover 11 on the outside of the feeding port 7 is tightened, and the feeding pipe 5 is locked by the clamp 10 on the lower side of the connecting pipe 9 to ensure the system sealing.

[0035] Please see the attached Figure 7 -Attached Figure 8 A mixing chamber 13 is provided inside the stirring tank 12, a stirring rod 15 is rotatably connected to the inside of the mixing chamber 13, a heating assembly 21 is provided on the outside of the stirring tank 12, and the heating assembly 21 includes a jacket 211, the jacket 211 is fixedly connected to the outside of the stirring tank 12, a heating block 212 is fixedly installed inside the jacket 211, and a temperature sensor 213 is installed in the inner cavity of the stirring tank 12;

[0036] Specifically, a heating block 212 is integrated in the jacket 211 on the outside of the stirring tank 12, which can uniformly heat the material in the mixing chamber 13. The temperature sensor 213 collects the temperature data in the mixing chamber 13 in real time and synchronously feeds back to the controller 22.

[0037] Please see the attached Figure 1 and attached Figure 6 The inner wall of the mixing tank 12 is provided with a cleaning assembly 23, the cleaning assembly 23 includes a connecting rod 231 fixedly connected to the outer side of the stirring rod 15, a scraper 232 fixedly connected to the outer side of the connecting rod 231, and a water inlet pipe 233 fixedly connected to the upper side of the storage tank 3.

The left side of the fan 251 is fixedly connected to a collection box 252, and the side of the collection box 252 away from the fan 251 is fixedly connected to a dust cover 253. , an electric push rod 255 is fixedly installed on the inner wall of the support frame 2, the telescopic end of the electric push rod 255 is fixedly connected to the dust cover 253, the interior of the collection box 252 is slidably connected to the extraction box 254, the lower side of the mixing tank 12 is fixedly connected to the discharge pipe 24, the dust cover 253 is slidably connected to the upper side of the discharge pipe 24, and a controller 22 is fixedly installed on the upper side of the base 1.

[0038] Specifically, after the mixing process is completed, water is injected into the mixing tank 12 through the water inlet pipe 233, and at the same time, the stirring rod 15 drives the outer connecting rod 231 and the scraper 232 to rotate. The scraper 232 moves close to the inner wall of the mixing tank 12 to scrape off the residual material and complete the cleaning. When discharging, the material is discharged through the discharge pipe 24 on the lower side of the mixing tank 12, and the fan 251 on the base 1 is started to drive the dust hood 253 to move to the top of the discharge pipe 24 under the adjustment of the electric push rod 255 to absorb the dust generated during the discharging process. The dust is filtered by the collection box 252 and temporarily stored in the extraction box 254, so as to ensure the safety and cleanliness of the production environment.

[0039] Working principle: When using this device, fix the storage tank 3 at the four corners of the support frame 2, align the flange base 41 with the mounting flange 42, and then fix it with fixing bolts 43 and nuts 44.

The controller 22 controls the solenoid valve 8 on the connecting pipe 9 on the right side of the storage tank 3 to open according to the preset ratio. The auxiliary material enters the mixing chamber 13 of the stirring tank 12 through the feeding pipe 5 and the feeding port 7. After the filling is completed, the sealing cover 11 on the outside of the feeding port 7 and the clamp 10 on the lower side of the connecting pipe 9 are connected to ensure sealing;

[0040] Then, the motor 14 is started to drive the stirring rod 15 to rotate in the mixing chamber 13. At the same time, the motor 2 18 on the connecting frame 19 is engaged with the outer gear ring 17 of the stirring tank 12 through the gear 16, driving the stirring tank 12 to rotate itself, forming a composite stirring motion of revolution and rotation. The heating block 212 in the outer jacket 211 of the stirring tank 12 heats the material, and the temperature sensor 213 feeds back the temperature to the controller 22 in real time to maintain a constant temperature. When the gear 16 needs to be lubricated, oil is supplied to the gear 16 through the oil tank 201 and the oil outlet pipe 202, and the control valve 203 adjusts the oil amount to reduce wear.

[0041] After mixing is completed, the outer connecting rod 231 of the stirring rod 15 drives the scraper 232 to rotate, and cooperates with the water inlet pipe 233 to inject water to clean the inner wall of the stirring tank 12. When discharging, the material is discharged through the discharge pipe 24 on the lower side of the stirring tank 12. The fan 251 on the base drives the dust hood 253 to adjust the position of the electric push rod 255 to absorb the dust at the discharge port. The dust is filtered by the collection box 252 and stored in the extraction box 254 to ensure production safety and environmental cleanliness.
