Description

Technical Field

[0001] This utility model relates to the field of material mixing technology, and in particular to a multifunctional intelligent negative pressure screw conveyor solid-liquid mixing device. Background Technology

[0002] A solid-liquid mixing device is a device used to thoroughly and uniformly mix solid and liquid materials, such as in the chemical, pharmaceutical, food, and coating industries. For example, in coating production, it is necessary to thoroughly mix solid pigment powder with liquid resin, solvent, etc., to obtain coating products with uniform color and stable performance, which is where a solid-liquid mixing device is used.

[0003] Traditionally, solid material powders are manually fed directly into the reactor. This method easily generates dust that pollutes the environment, and the material inside the reactor is difficult to dissolve, resulting in long deagglomeration and homogenization times. Furthermore, because the powder is lightweight, has small particles, and irregular shapes, it has poor flowability. When the powder has poor flowability, it tends to accumulate near the feed inlet when entering the screw conveyor, causing equipment blockage. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a multifunctional intelligent negative pressure screw conveyor solid-liquid mixing device, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A multifunctional intelligent negative pressure screw conveyor solid-liquid mixing device, comprising a solid material feeding station and a solid material temporary storage chamber. Both the solid material feeding station and the solid material temporary storage chamber are equipped with screw conveyors at their bottoms. The solid material feeding station, the solid material temporary storage chamber, and the screw conveyors are interconnected. The discharge end of the screw conveyor is connected to the inlet end of the solid material temporary storage chamber. Discharge pipes are provided on both sides of the outer wall of the screw conveyor connected to the bottom of the solid material temporary storage chamber. A powder-absorbing homogenizer is installed on the outer wall of each of the two discharge pipes. The outer walls of the two discharge pipes are interconnected with the powder-absorbing homogenizer. One end of each of the two powder-absorbing homogenizers is connected to a reaction vessel. The discharge ends of each of the two reaction vessels are connected to the other end of the powder-absorbing homogenizer. The solid material feeding station, screw conveyor, powder-absorbing homogenizer, reaction vessel, and solid material temporary storage chamber are all interconnected through sealed conveying pipes. A dredging component is provided inside the screw conveyor.

[0006] First, the material is fed into the solid material feeding station. The material is then conveyed to the solid material temporary storage chamber by a screw conveyor. From there, the material is conveyed at a constant speed by a screw conveyor at the bottom of the storage chamber to the powder homogenizer. The powder homogenizer continuously disperses the solid material online. Through the high-shear stator-rotor structure in the working chamber, any possible agglomerates are dispersed. The material is then conveyed to the reaction vessel by the powder homogenizer, effectively improving the material mixing efficiency and solving the problem of long deagglomeration and homogenization time. The material is transported entirely in a closed pipeline, eliminating the risk of dust flying and flash explosion. At the same time, one screw conveyor can be used by two powder homogenizers, simplifying the process and reducing costs. The screw conveyor is equipped with a dredging component.

[0007] In a preferred embodiment of this invention, the unblocking assembly includes a first gear and a second gear. One side of each gear is rotatably connected to the outer wall of the screw conveyor, and the first and second gears mesh with each other. An external motor is fixedly connected to the other side of the first gear. A support plate is fixedly connected to the inner wall of the screw conveyor, dividing the interior of the screw conveyor into two independent chambers. A discharge port is formed on the upper surface of the support plate, the size of which is adapted to the size of the material outlet on the lower surface of the solid material storage chamber. A connecting rod is fixedly connected to the inner wall of the second gear, one end of which penetrates and extends into the interior of the screw conveyor, and a worm gear is fixedly connected to the end of the connecting rod. The worm gear has a connecting rod two fixedly connected to its end, and a fixing plate rotatably connected to the end of the connecting rod two. The fixing plate is fixedly connected to the upper surface of the support plate. A worm wheel is meshed with the outer wall of the worm gear. A protective shell is installed on the outer walls of the worm gear and the worm wheel. The worm wheel is rotatably connected inside the protective shell. Both ends of the worm gear penetrate the protective shell and extend to the outside, where they are fixedly connected to connecting rod one and connecting rod two. Fixing rods are fixedly connected to both sides of the outer wall of the protective shell. The other end of each fixing rod is fixedly connected to the inner wall of the discharge port. A helical shaft is fixedly connected to the inner wall of the worm wheel. The helical shaft penetrates the protective shell and extends into the interior of the solid material temporary storage chamber. Helical blades are fixedly connected to the outer wall of the helical shaft.

[0008] The support plate divides the interior of the screw conveyor into two independent chambers. The unblocking component is located in the upper chamber of the screw conveyor. During operation, the motor drives gear one to rotate, and gear two meshes with gear one, causing gear two to rotate in tandem. Under the rotation of gear two, connecting rod one, connecting rod two, and worm also rotate. The rotation of the worm drives the worm wheel to rotate, and at the same time, the screw shaft and screw blades also rotate. Since the screw shaft and screw blades extend into the material outlet of the solid material storage chamber, the material accumulated in the material outlet is unblocked by the rotation of the screw shaft and screw blades. The material flows into the lower chamber of the screw conveyor through the discharge port on the surface of the support plate. The protective shell outside the worm wheel and worm prevents the material from affecting them, thus avoiding the problem of blockage caused by the light and poor flowability of the material in the storage chamber.

[0009] The beneficial effects of this utility model are: by conveying materials in a sealed pipeline, the risks of dust flying and flash explosion are effectively avoided. At the same time, it solves the problem of traditional manual feeding of materials directly into the reaction vessel. Solid materials are difficult to dissolve in slurry, the deagglomeration and homogenization time is long, and one screw conveyor can be used for two sets of powder suction homogenizers, saving costs.

[0010] This invention, through the cooperation of the conveying components, extends the screw shaft and screw blades into the material outlet of the solid material temporary storage chamber. At this time, the material accumulated in the material outlet is cleared by the rotation of the screw shaft and screw blades, avoiding the problem of blockage caused by the light weight and poor flowability of the material in the temporary storage chamber.

[0019] Example 1

[0020] Please see Figure 1 A multifunctional intelligent negative pressure screw conveyor solid-liquid mixing device includes a solid material feeding station 1 and a solid material temporary storage chamber 5. Both the solid material feeding station 1 and the solid material temporary storage chamber 5 are equipped with screw conveyors 2 at their bottoms. The solid material feeding station 1, the solid material temporary storage chamber 5, and the screw conveyors 2 are interconnected. The discharge end of the screw conveyor 2 is connected to the feed end of the solid material temporary storage chamber 5. Discharge pipes are provided on both sides of the outer wall of the screw conveyor 2 connected to the bottom of the solid material temporary storage chamber 5. A powder-absorbing homogenizer 3 is installed on the outer wall of each of the two discharge pipes, and the outer walls of the two discharge pipes are interconnected with the powder-absorbing homogenizer 3. One end of each of the two powder-absorbing homogenizers 3 is connected to a reaction vessel 4, and the discharge ends of each of the two reaction vessels 4 are connected to the other end of the powder-absorbing homogenizer 3. The solid material feeding station 1, screw conveyor 2, powder-absorbing homogenizer 3, reaction vessel 4, and solid material temporary storage chamber 5 are all interconnected through sealed conveying pipes. A dredging component 7 is installed inside the screw conveyor 2.

[0021] First, the material is fed into the solid material feeding station 1. The material is then conveyed at a constant speed to the solid material temporary storage chamber 5 by the screw conveyor 2. The material is then conveyed at a constant speed from the bottom of the solid material temporary storage chamber 5 to the powder suction homogenizer 3 by the screw conveyor 2. The powder suction machine continuously disperses the solid material online. Through the high-shear stator and rotor structure of the working chamber, any possible agglomerates are dispersed. The powder suction homogenizer 3 then conveys the material to the reaction vessel 4, effectively improving the material mixing efficiency and solving the problem of long material deagglomeration and homogenization time. The material is transported in a closed pipeline throughout the process, eliminating the risk of dust flying and flash explosion. At the same time, one screw conveyor 2 can be used by two powder suction homogenizers 3, which is simple and cost-effective. The screw conveyor 2 is equipped with a dredging component 7.

[0022] Please see Figures 1 to 6 In this embodiment, the unblocking component 7 includes a first gear 701 and a second gear 702. One side of each gear 701 and the second gear 702 is rotatably connected to the outer wall of the screw conveyor 2. The first gear 701 and the second gear 702 mesh with each other. An external motor is fixedly connected to the other side of the first gear 701. A support plate 6 is fixedly connected to the inner wall of the screw conveyor 2, dividing the interior of the screw conveyor 2 into two independent chambers. A discharge port 710 is provided on the upper surface of the support plate 6. The size of the discharge port 710 is adapted to the size of the material outlet on the lower surface of the solid material storage chamber 5. A connecting rod 703 is fixedly connected to the inner wall of the second gear 702. One end of the connecting rod 703 penetrates and extends into the interior of the screw conveyor 2. A worm gear 707 is fixedly connected to the end of the connecting rod 703. A connecting rod 705 is fixedly connected to the upper surface of the support plate 6. A worm wheel 708 is meshed with the outer wall of the worm 707. A protective shell is installed on the outer walls of the worm 707 and the worm wheel 708. The worm wheel 708 is rotatably connected inside the protective shell. Both ends of the worm 707 penetrate the protective shell and extend to the outside, where they are fixedly connected to the connecting rod 703 and the connecting rod 705. A fixing rod 711 is fixedly connected to both sides of the outer wall of the protective shell. The other end of the fixing rod 711 is fixedly connected to the inner wall of the discharge port 710. A spiral shaft 709 is fixedly connected to the inner wall of the worm wheel 708. The spiral shaft 709 penetrates the protective shell and extends into the interior of the solid material temporary storage chamber 5. A spiral blade 704 is fixedly connected to the outer wall of the spiral shaft 709.

[0023] The support plate 6 divides the interior of the screw conveyor 2 into two independent chambers. The unblocking component 7 is installed in the upper chamber of the screw conveyor 2. During operation, the motor drives gear 1 701 to rotate, and gear 2 702 meshes with gear 1 701, causing gear 2 702 to rotate in conjunction. Under the rotation of gear 2 702, connecting rod 1 703, connecting rod 2 705, and worm 707 also rotate. The rotation of worm 707 drives worm wheel 708 to rotate. At the same time as worm wheel 708 rotates, screw shaft 709 and screw blade 704 also rotate. Since screw shaft 709 and screw blade 704 extend into the material outlet of solid material temporary storage chamber 5, the material accumulated in the material outlet is unblocked by the rotation of screw shaft 709 and screw blade 704. The material flows into the lower chamber of screw conveyor 2 through the discharge port 710 on the surface of support plate 6 for conveying, avoiding the problem of blockage caused by the light weight and poor flowability of the material in the temporary storage chamber.

[0024] Working principle: First, the material is fed into the solid material feeding station 1. The material is then conveyed to the solid material temporary storage chamber 5 by the screw conveyor 2. The material is then uniformly conveyed by the screw conveyor 2 at the bottom of the solid material temporary storage chamber 5 to the powder homogenizer 3. The powder homogenizer 3 then conveys the material to the reaction vessel 4. The support plate 6 divides the interior of the screw conveyor 2 into two independent chambers. The unblocking component 7 is installed in the upper chamber of the screw conveyor 2. During the operation of the screw conveyor 2, the motor drives the gear 1 701 to rotate. At the same time, the gear 2 702 meshes with the gear 1 701. At this time, the gear 2 702 is linked. Under the rotation of the gear 2 702, the connecting rod... 703, 705, and 707 rotate simultaneously. The rotation of 707 drives 708 to rotate. Simultaneously, 709 and 704 rotate. Since 709 and 704 extend into the material outlet of the solid material storage chamber 5, the material accumulated in the material outlet is cleared by the rotation of 709 and 704. The material flows into the lower chamber of the screw conveyor 2 through the discharge port 710 on the surface of the support plate 6 for conveying, thus avoiding the problem of blockage caused by the light weight and poor flowability of the material in the storage chamber.
