Description

Technical Field

[0001] The invention relates to the field of additive production, and more specifically to a coating additive production preheating device. Background Art

[0002] Coating additives, also known as paint auxiliary materials, are auxiliary materials for preparing coatings. They can improve coating performance and promote coating film formation. Common ones include driers, emulsifiers, dispersants, etc. Different coating additives have different raw materials for production, and they are in solid, liquid, powder, solid-liquid mixed states, etc. Coating additives need to be preheated during production. Preheating can speed up the movement of reactant molecules and increase the frequency of collisions between molecules, thereby increasing the rate of chemical reactions. In the production process of coating additives, many reactions need to be carried out at a certain temperature. Preheating can ensure that the reaction is carried out within the optimal temperature range, thereby improving production efficiency. When traditional preheating devices preheat materials in different states, thermal stratification is prone to occur during preheating because the fluidity of the materials is different due to their different states, causing part of the material to react extremely quickly while the other part of the material has not yet reached the preheating temperature, resulting in incomplete reaction.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0025] See also Figures 1 to 9A coating additive production preheating device comprises a heat preservation tank body 1, a plurality of uniformly distributed heating rods 17 are fixedly mounted on the inner upper surface of the heat preservation tank body 1, a dispersing component 2 is provided on the inner sliding card of the heat preservation tank body 1, and the dispersing component 2 is used to disperse materials in different states, a grinding component 3 is rotatably mounted on the inner bottom end of the heat preservation tank body 1, and the grinding component 3 is used to cooperate with the dispersing component 2 to grind the agglomerated materials and bulk materials, and the dispersing component 2 divides the inner part of the heat preservation tank body 1 into two upper and lower chambers, and the upper part of the dispersing component 2 The second chamber is located below the first chamber dispersion component 2, a one-way valve 14 is fixedly installed on the top of the insulation tank body 1, and the one-way valve 14 is connected to the first chamber. A solid feed port 11 and a liquid feed port 12 connected to the first chamber are fixedly installed on the external upper surface of the insulation tank body 1, and a discharge port 13 connected to the second chamber is fixedly installed on the external lower end of the insulation tank body 1. Valves 16 are installed on the solid feed port 11, the liquid feed port 12 and the discharge port 13, and a spindle motor 15 is fixedly installed on the external bottom end of the insulation tank body 1.

[0026] During actual use, first close the valve 16 on the discharge port 13, add solid materials into the interior of the heat-insulating tank body 1 through the solid feed port 11, or use the liquid feed port 12 to add liquid raw materials into the interior of the heat-insulating tank body 1, or add them at the same time. In the initial state, the dispersing component 2 is in contact with the inner bottom end of the heat-insulating tank body 1, and the second chamber is completely covered. At this time, the material will fall on the top of the dispersing component 2. When the adding is completed, close the valves 16 on the solid feed port 11 and the liquid feed port 12, and then drive the spindle motor 15 to work. The operation of the spindle motor 15 can drive the dispersing component 2 to rise and fall reciprocally. When the dispersing component 2 rises and falls, it can continuously change the states of the first chamber and the second chamber. When the dispersing component 2 rises, the first chamber changes from a balanced state to a positive pressure state, and the second chamber changes to a negative pressure state. At this time, the material will be sucked into the interior of the second chamber. If the material is solid, it will be carried by the air through the dispersing component 2 into the interior of the second chamber until the first chamber and the second chamber return to a state of equilibrium. When the dispersing component 2 descends, the material in the second chamber can be scattered into the interior of the first chamber. If the material is in a liquid state or a solid-liquid mixture, the liquid will be driven by the dispersing component 2 to be sprayed into the interior of the first chamber. If the material is a powdered solid, it will be carried by the air to be blown into the interior of the first chamber as the dispersing component 2 moves. Because the dispersing component 2 drives the material to be sprayed, the contact area between the sprayed material and the air inside the first chamber increases. Under the action of the heating rod 17, the material can be quickly preheated. Whether it is a solid material, a liquid material, or a solid-liquid mixture, it can be preheated evenly, thoroughly, and quickly. It can handle materials in different states, and there will be no situation where materials in different states are not preheated thoroughly during preheating.

[0027] The dispersion component 2 includes a dispersion shell 21, a first conical cylinder 22 is fixedly installed at the bottom end of the dispersion shell 21, a leakage groove is provided at the bottom end of the dispersion shell 21, a lower sealing plate 211 is provided at a position of the dispersion shell 21 corresponding to the leakage groove, a plurality of evenly distributed guide rods 212 are fixedly installed on the upper surface of the lower sealing plate 211, the guide rods 212 are slidably clamped inside the dispersion shell 21, a spring 213 is fixedly connected between the guide rods 212 and the dispersion shell 21, the lower sealing plate 211 blocks the leakage groove, a plurality of evenly distributed sealing rubber rings 214 are fixedly installed at the outer ring of the dispersion shell 21, a central shell 23 is fixedly installed at the top end of the first conical cylinder 22, two mutually symmetrical support frames 231 are fixedly installed at the top end of the central shell 23, two symmetrical rotating plates 232 are provided between the two support frames 231, the two rotating plates 232 are hinged to each other, the hinged positions of the two rotating plates 232 are rotatably connected to the support frame 231, and a torsion spring 233 is fixedly connected between the two rotating plates 232.

[0028] When the material enters the heat preservation tank body 1, it will first fall into the dispersion shell 21. At this time, when the dispersion shell 21 rises, the material and air inside the first chamber will push the lower sealing plate 211. At this time, the leakage groove is in an open state. As the dispersion shell 21 rises, the material and air will pass through the leakage groove into the second chamber. At this time, the spring 213 is stretched. When the dispersion shell 21 descends, under the action of pressure and spring 213, the lower sealing plate 211 quickly returns to its original position to block the leakage groove. At this time, the material and air inside the second chamber will pass through the central shell 23 to push the two rotating plates 232. At this time, the rotating plates 232 are pushed open to make the central shell 23 in an open state, and the torsion spring 233 is stretched. Passing through the central shell 23, the second chamber enters the interior of the first chamber. Because of the central shell 23, the inner diameter of the central shell 23 is much smaller than the inner diameter of the heat preservation tank body 1. Therefore, when the dispersion shell 21 descends, the material and air inside the second chamber increase their flow rate due to the rapid decrease in the inner diameter of the pipeline, and can be quickly sprayed into the interior of the first chamber as the dispersion shell 21 descends. The torsion spring 233 and the spring 213 are provided to enable the rotating plate 232 and the lower sealing plate 211 to respond quickly to the rapid rise and fall of the dispersion shell 21 and close, so that the dispersion shell 21 is more stable during the rise and fall process, and prevent the situation that the lower sealing plate 211 and the rotating plate 232 are not closed in time due to the excessive speed of the dispersion shell 21.

[0029] A sliding shell 24 is movably mounted inside the central shell 23, and a plurality of evenly distributed second corrugated grooves 241 are provided on the outer surface of the sliding shell 24. A central rod 242 is fixedly mounted at the inner center of the sliding shell 24 via a bracket, and the central rod 242 is fixedly mounted on the grinding component 3. A plurality of spherical bumps 234 corresponding to the second corrugated grooves 241 are fixedly mounted inside the central shell 23, and the spherical bumps 234 are movably mounted inside the corresponding second corrugated grooves 241.

[0030] When the spindle motor 15 rotates, it will drive the grinding component 3 to rotate, and the rotation of the grinding component 3 will drive the center rod 242 to rotate. The rotation of the center rod 242 can drive the sliding shell 24 to rotate. When the sliding shell 24 rotates, the spherical protrusion 234 will slide along the inside of the second corrugated groove 241. Because the second corrugated groove 241 is wavy, and the dispersion shell 21 is slidably mounted inside the insulation tank body 1, and the center shell 23 is fixedly connected to the dispersion shell 21, as the sliding shell 24 rotates, the center shell 23 will be driven to rise and fall reciprocatingly, so as to facilitate the spraying of materials in different states for uniform preheating.

[0031] A crushing plate 25 is slidingly clamped at the upper end of the inner part of the dispersion shell 21, an inclined plate 251 is fixedly installed on the upper surface of the crushing plate 25, and a plurality of evenly distributed connecting plates 252 are fixedly installed on the side surface of the crushing plate 25. A slide groove for sliding the connecting plate 252 is opened on the dispersion shell 21, and the connecting plate 252 passes through the slide groove and is fixedly installed inside the heat-insulating tank body 1. A slide plate 253 for sealing the slide groove is fixedly installed on the upper and lower surfaces of the connecting plate 252. A first mesh plate 254 is provided below the slide plate 253, and the first mesh plate 254 is fixedly installed inside the dispersion shell 21. A conical mesh plate 255 is fixedly installed in the middle of the first mesh plate 254, and the conical mesh plate 255 is fixedly installed on the outer surface of the central shell 23. There is a leakage groove between the crushing plate 25 and the central shell 23.

[0032] When the material enters the insulation tank body 1, it will first fall on the inclined plate 251. Because the inclined plate 251 is inclined, the material will slide through the leakage trough and fall on the conical mesh plate 255. The material with a smaller diameter will directly pass through the conical mesh plate 255, while the material with a larger diameter will be blocked by the conical mesh plate 255 and roll down on the upper surface of the first mesh plate 254. When the dispersion shell 21 rises, because the crushing plate 25 is fixed to the inside of the insulation tank body 1 through the connecting plate 252, the dispersion shell 21 will drive the first mesh plate 254 and the conical mesh plate 255 to rise when it rises. At this time, the first mesh plate 254 is relatively close to the crushing plate 25. The slide plate 253 is used to ensure the sealing degree inside the dispersion shell 21 to prevent material leakage. The crushing plate 25 can crush the large particles on the first mesh plate 254 to prevent the material from containing large particles and causing incomplete heating, and prevent the material from agglomerating, thereby further increasing the preheating effect.

[0033] A first rotating ring 26 is provided below the first mesh plate 254, and the first rotating ring 26 is rotatably installed in the middle of the dispersion shell 21. An annular cone plate 261 is fixedly installed at the inner ring of the first rotating ring 26, and the annular cone plate 261 is rotatably clamped on the inner surface of the dispersion shell 21. Two symmetrically distributed round-head slide bars 262 are fixedly installed at the outer ring of the first rotating ring 26. A first corrugated groove 18 corresponding to the round-head slide bar 262 is provided at the inner ring of the heat-insulating tank body 1, and the round-head slide bar 262 is movably clamped inside the first corrugated groove 18. A central grinding disk 263 is provided at the center of the first rotating ring 26, and the central grinding disk 263 is fixedly installed on the central shell 23. A grinding groove 264 is provided between the annular cone plate 261 and the central grinding disk 263, and the interior of the annular cone plate 261 is separated by the central grinding disk 263 to form a transfer chamber 201.

[0034] When the material passes through the first mesh plate 254 and the conical mesh plate 255, it will fall on the central grinding disc 263. The material that meets the diameter standard will pass through the grinding groove 264 and enter the interior of the transfer chamber 201. If the diameter is larger and does not meet the standard, it will stay in the grinding groove 264. As the dispersion shell 21 rises and falls reciprocatingly, the round-headed slide bar 262 will continue to slide along the first corrugated groove 18. Because the first corrugated groove 18 is wavy, the round-headed slide bar 262 can be continuously driven to rotate. Because the lifting speed of the dispersion component 2 is fast, the round-headed slide bar 262 can cross the balance point under the action of inertia. Continuous rotation, and then the rotation of the round-headed slide bar 262 will drive the first rotating ring 26 and the annular cone plate 261 to rotate. When the annular cone plate 261 rotates, the material inside the grinding groove 264 will be ground. The gap of the grinding groove 264 gradually decreases from top to bottom. By setting the annular cone plate 261 and the round-headed slide bar 262, the device can automatically grind when in use, and crush particles with larger diameters into powdery materials, which are convenient for subsequent blowing and evenly dispersing inside the first chamber, preventing the occurrence of agglomeration or agglomeration of powder when encountering liquid, and further improving the efficiency of heating and mixing.

[0035] The grinding component 3 includes a grinding plate 31, a second conical cylinder 32 is fixedly installed in the middle of the grinding plate 31, and the second conical cylinder 32 is in contact with the lower surface of the first conical cylinder 22. A gear ring 33 is fixedly installed in the middle of the grinding plate 31, and a plurality of evenly distributed planetary gears 34 are meshed at the inner ring of the gear ring 33. The planetary gears 34 are rotatably mounted on the inner bottom surface of the heat preservation tank body 1. A sun gear 35 is provided at the center of the gear ring 33, and the sun gear 35 is meshed with the plurality of planetary gears 34. The driving end of the spindle motor 15 passes through the heat preservation tank body 1. The tank body 1 is fixedly mounted on the lower surface of the sun gear 35, a connecting rod 36 is fixedly mounted on the upper surface of the sun gear 35, a second rotating ring 37 is rotatably mounted on the second conical cylinder 32, the connecting rod 36 is fixedly connected to the second rotating ring 37 through a bracket, a plurality of evenly distributed mating teeth 371 are fixedly mounted on the outer ring of the second rotating ring 37, a stirring blade 27 is rotatably mounted at a position corresponding to the first conical cylinder 22 and the second rotating ring 37, a plurality of latching teeth mating with the mating teeth 371 are fixedly mounted on the inner ring of the stirring blade 27.

[0036] When the dispersion shell 21 descends to the bottom, the first conical cylinder 22 and the second conical cylinder 32 are fitted together. When the spindle motor 15 is working, it will drive the sun gear 35 to rotate, and the rotation of the sun gear 35 will drive multiple planetary gears 34 to rotate. The planetary gears 34 are installed in the inside of the heat preservation tank body 1, which is equivalent to the planetary gears 34 being unable to revolve. Then, when the sun gear 35 rotates, the ring gear 33 will decelerate. When the ring gear 33 rotates, it can drive the grinding plate 31 and the second conical cylinder 32 to rotate. When the second conical cylinder 32 rotates, it can drive the center rod 242 to rotate. The center rod 242 drives the sliding shell 24 to rotate, thereby realizing the reciprocating lifting of the dispersion component 2.

[0037] During actual operation, the material will first pass through the crushing plate 25 and the grinding groove 264 to enter the interior of the transfer chamber 201. When the dispersion shell 21 descends, the latching teeth on the stirring blade 27 are pushed by the matching teeth 371 on the second rotating ring 37. Then, when the dispersion shell 21 descends to the bottom, the stirring blade 27 can be driven by the second rotating ring 37 to rotate. Because the rotation speed of the sun gear 35 is higher than that of the ring gear 33 and the grinding plate 31, the stirring blade 27 will be driven to rotate rapidly. When the stirring blade 27 is driven to rotate rapidly, the material inside the transfer chamber 201 will be pre-mixed, so that materials of different types and states are mixed evenly, which is convenient for subsequent spraying, so that each material can be evenly heated.

[0038] When unloading, it is only necessary to open the valve 16 on the discharge port 13. As the dispersion component 2 moves back and forth, the material will be squeezed out of the device through the discharge port 13, which not only enables unloading but also gives the material a certain output kinetic energy. As the dispersion shell 21 continues to rise and fall, the material on the inner wall of the insulation tank body 1 can also be scraped off.

[0039] Working principle: When actually using, first close the valve 16 on the discharge port 13, add solid materials to the inside of the heat preservation tank body 1 through the solid feed port 11, or use the liquid feed port 12 to add liquid raw materials to the inside of the heat preservation tank body 1. After adding, close all valves 16, and then open the spindle motor 15 at this time. The spindle motor 15 can drive the grinding component 3 to rotate. When the grinding component 3 rotates, it can drive the dispersion component 2 to achieve reciprocating lifting. When the dispersion component 2 rises, the material will be sucked into the second chamber. When the dispersion component 2 descends, the material in the second chamber can be thrown into the first chamber. Whether it is a powder material, a liquid material, or a solid-liquid mixture, it can be driven to spray into the first chamber. Because the spraying method increases the contact area between the material and the heating rod 17 and the air inside the first chamber, it can be better preheated. After the preheating and mixing are completed, there is no need to stop the machine. Just open the valve 16 on the discharge port 13. As the dispersion component 2 moves back and forth, the material will continuously enter the second chamber and be transported out of the device through the discharge port 13.

[0040] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
