Description

Technical Field

[0001] The invention relates to the technical field of defoamer production, and in particular to an intelligent production line and a production control system for a composition. Background Art

[0002] Silicone defoamer is a defoaming composition based on polydimethylsiloxane (PDMS) supplemented with white carbon black, emulsifier and other components. It is widely used in coatings, papermaking, fermentation and other fields. In the production process, white carbon black is a hydrophobic powder and is easy to agglomerate in liquid silicone oil. If it is directly added to the mixing kettle, it is easy to cause agglomeration and uneven dispersion, affecting product performance. Therefore, before putting it into the mixing kettle, a premixing device with a stirring function is required to fully wet and preliminarily disperse the white carbon black and silicone oil to reduce the viscosity of the system, ensure the efficiency and uniformity of the subsequent high-speed stirring process, and improve the quality stability of the final product.

[0003] In the prior art, after white carbon black and part of silicone oil are premixed in a premixing device, a pump is generally used to deliver the mixture into a mixing kettle. Since the viscosity of the mixture of white carbon black and silicone oil is relatively high, the feeding speed of the pump is slow, and the high-viscosity material has a large movement resistance in the pump, resulting in a significant reduction in the conveying speed, extending the feeding time, and reducing the cycle efficiency of the entire production line. In addition, the white carbon black in the mixture is in the form of micron-sized particles. Although the particle size is small, it is easy to aggregate and agglomerate in a viscous medium and easily clog the pump. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that in the prior art, after white carbon black and part of silicone oil are premixed in a premixing device, a pump body is generally used to feed the mixture into a mixing kettle. Due to the high viscosity of the mixture of white carbon black and silicone oil, the feeding speed of the pump body is slow, and the high-viscosity material has a large movement resistance in the pump, resulting in a significant reduction in the conveying speed, prolonged feeding time, and reduced beat efficiency of the entire production line. In addition, the white carbon black in the mixture is in the form of micron-sized particles. Although the particle size is small, it is easy to aggregate and agglomerate in a viscous medium and easily clog the pump body.

The premixing assembly rotates at the same time to assist in cleaning the premixing barrel.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The present invention has a premixing cylinder fixedly arranged above the mixing kettle, an extrusion disk movably inserted into the top of the premixing cylinder, a closing disk arranged at the bottom of the premixing cylinder for closing or opening the bottom of the premixing cylinder, and an extrusion assembly and a premixing assembly arranged on the extrusion disk. When the premixing assembly premixes the materials inside the premixing cylinder, the extrusion assembly and the closing disk are controlled by a safety interlock assembly. After the premixing work is completed, the mixed materials inside the premixing cylinder are automatically released into the mixing kettle, and uniform pressure is directly applied to the premix to release it from the bottom closing disk, thereby solving the problems of slow material delivery and easy clogging of traditional pumps, and is particularly suitable for high-viscosity systems such as white carbon black + silicone oil, and can achieve rapid emptying.

[0016] 2. The present invention is provided with a safety interlock assembly near the premixing barrel. The purely mechanical safety interlock assembly prevents the extrusion assembly from moving downward when the premixing barrel is performing a mixing action and the closing disk closes the bottom of the premixing barrel. The extrusion assembly can move downward only when the closing disk is removed from the bottom of the premixing barrel to open the bottom of the premixing barrel. The extrusion assembly is locked by a mechanical structure to prevent premature downward pressure from causing the mixture to be squeezed and hit the closing disk, thereby avoiding damage to the structure or causing equipment jamming. The interlock structure physically blocks this risky action, eliminating the need for personnel to judge the status, and greatly reducing the safety hazards caused by operational errors.

[0017] 3. The present invention is provided with a blocking arc rod on the top of the lower pressure plate. When the extrusion assembly moves downward to quickly release the mixed material into the mixing kettle, the simple structure of the blocking arc rod can automatically stop the entire premixing barrel from entering the material to be mixed, thereby preventing new material from mistakenly entering the premixing barrel during the discharge process. This structure does not require electronic control and realizes the physical interlocking of feeding and discharging, thereby ensuring the continuity of the premixing process and the purity of the material batch. It has a simple structure and reliable operation.

[0018] 4. The present invention is provided with a safety liquid guiding component near the premixing barrel. The safety liquid guiding component with a purely mechanical structure can prevent cleaning water from entering when the premixing barrel is mixing materials. After the bottom of the premixing barrel is closed by the closing disk, the safety liquid guiding component guides the cleaning water into the interior of the premixing barrel and cuts off the passage between the materials to be mixed and the premixing barrel to prevent the materials to be mixed from entering the interior of the premixing barrel. An interlocking mutual exclusion is formed among cleaning, closing and feeding to ensure that the three fluids (cleaning water, mixed materials and raw materials to be mixed) will never cross or be mixed by mistake, and the operation is more intelligent.

A release hole 291 is provided on the side of the blocking rod 29. A docking tube 32 is fixedly arranged on the top of the fixing ring 10.

[0042] The specific implementation steps and principles of the present invention are as follows: When the entire equipment is waiting for premixing and discharging, the safety liquid guiding assembly does not close the feed pipe 172, but closes the water pipe 33 and the drain pipe 24. The switching cylinder 26 extends out, the release hole 291 of the material blocking rod 29 is inside the feed pipe 172, the water blocking hole 310 of the water blocking rod 31 is outside the water pipe 33, the drain hole 252 of the switching rod 25 is outside the drain pipe 24, and the water inlet hole 271 is connected to the water inlet pipe 171.

[0043] When the entire equipment is performing premixing, the closing disk 22 is at the bottom of the premixing barrel 17, and the downward pressure cross bar 9 is not directly above the driven rod 13.
