Technical Field

[0001] The present application belongs to the technical field of coating compounding, and specifically relates to a multi-element nano coating compounding device and a compounding method. Background Art

[0002] During the construction process of refractory spray coating, the constituent materials are repeatedly and continuously impacted to compact the sprayed materials, so the spray coating has good density and mechanical strength. It can be applied to hot air duct system, blast furnace throat, furnace top and gas outlet pipe system, furnace bottom foundation, blast furnace and hot blast furnace lining. The construction of refractory spray coating actually combines transportation, pouring or tamping into one process, without or only requiring single-sided template, simple process, high efficiency and good adaptability.

[0003] During the construction process of refractory spray coating, repeated and continuous impacts of cement, aggregate and other constituent materials cause the sprayed materials to be compacted, so that the spray coating has good density and mechanical strength. Heavy refractory spray coating is relative to lightweight refractory spray coating. Lightweight spray coating refers to a density of 0.5-1.3g / cm3, and medium-heavy spray coating refers to a density of 1.3-1.8g / cm3. Then the density of heavy spray coating is the largest, greater than 1.8g / cm3. Lightweight spray coating is used as thermal insulation and heat insulation lining. Medium-heavy spray coating can be used as heat insulation lining and low and medium temperature atmosphere furnace working lining, while heavy spray coating is mainly used as high temperature working lining. Refractory spray coating is mainly used as sealing material for the lining of industrial kiln thermal equipment, and can be applied to hot air duct system, blast furnace throat, furnace top and gas outlet pipe system, furnace bottom foundation, blast furnace and hot blast furnace lining.

[0005] Chinese invention patent CN108097102A provides a coating batching device, which solves the technical problems that the existing mixer has a too simple structure, cannot quickly complete the mixing of the coating, and has a slow mixing speed.

[0007] As the amount of material added inside the batching kettle changes, the height of the paint inside the batching kettle keeps changing.

[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] First embodiment

[0045] The use of high-speed airflow as a refractory material carrier for spraying construction of refractory materials is called sprayed refractory materials, which include spray coatings for repairing damaged linings and spray coatings for constructing new linings. People now call this type of construction method a moldless construction method, which has become one of the future development directions of amorphous refractory materials.

[0046] Spraying refractory materials, whether spraying to repair furnace lining or spraying to build new lining, can be divided into two categories according to the state of the sprayed material on the sprayed working surface: cold material spraying method and molten material spraying method.

[0047] There are five types of cold material injection methods:

[0048] ① Mud injection method;

[0049] ②Dry spraying method;

[0050] ③ Semi-wet spraying method (also called tidal spraying method);

[0051] ④Mixed injection method;

[0052] ⑤Wet spraying method.

[0053] The molten material spraying method is divided into: flame spraying method, plasma spraying method, and slag splashing furnace protection method.

[0054] Cold material injection materials are mainly composed of various granular and powdery refractory materials. The binder content is generally low, and it often contains an appropriate amount of solvent to promote sintering. A small amount of water is added during construction and stirring.

[0055] The material of the fine powder used for the spraying material should be selected according to the maximum possible operating temperature in the furnace, the temperature fluctuation range, and the requirements of the slag properties on the lining properties. When the spraying material is used to coat the lining, its material should be equivalent to the original lining, and the chemical properties, refractoriness, high temperature strength deformation, linear expansion, etc. of the two should be similar. The limit particle size of the granular material should be appropriately selected according to the thickness of the spraying layer of the spraying machine structure and the spraying method (such as wet method or dry method).

[0056] Improper particle size selection has a great impact on the rebound loss of the spray material. The rebound loss refers to the amount of material that rebounds when sprayed on the substrate and fails to adhere to it. The particle grading not only affects the density of the spray layer structure, but also has a great relationship with the level of rebound loss of adhesion.

[0057] Generally speaking, if the wet spraying material is too coarse or has too many or too few coarse particles, it is not good for the density of the spraying layer. Moreover, coarse particles and a large number of coarse particles often lead to large rebound losses.

[0058] Wet jetting construction has been widely used in the construction or repair of linings of blast furnace tapping hooks, torpedo tanks, steel ladle, interlayer, rotary kiln waste incinerator, etc.

[0059] Flame spraying materials are composed of metal powder, corundum, magnesia and other refractory raw materials. Metal powder is both a fuel and a molten binder. Sometimes only a small amount of solvent is added to facilitate its rapid sintering. The flame spraying method (melt spraying method) uses propane gas as a fuel flame spraying method. It uses propane gas and oxygen to burn to form a flame to heat the spray refractory material powder to a molten state (or semi-molten state) and spray it on the surface of the lining to be repaired. After curing, the coating strength is equivalent to or higher than the original lining strength, and it has a strong bonding force with the original lining and a high density, so its refractoriness is higher than that of the cold material spray coating.

[0060] The production process of refractory spray coating is quite flexible. It can be freely composed of various refractory raw materials according to scientific basis. We can divide it into:

[0061] 1. Corundum spray coating: corundum is used as raw material, and its Al2O3 content is generally greater than 90%;

[0062] 2. Aluminum-silicon spray coating: Depending on the aluminum content and the raw materials used, it can be divided into mullite spray coating (using electric baking or sintering mullite as raw material), high-aluminum spray coating (using alumina clinker as raw material), and clay spray coating (using coke as the main raw material);

[0063] 3. Silicon spray coating: using silica as raw material, its SiO2 content is above 90%;

[0064] 4. Magnesium spray material: sintered or fused magnesia is used as raw material, and its MgO content is usually greater than 80%.

[0065] In addition, if the spray coating is made of magnesia sand as aggregate and magnesia sand powder and chrome ore powder as the matrix, it is a magnesia-chrome spray coating;

[0066] If the matrix of the spray coating is composed of magnesia powder and alumina powder, it is a magnesium-aluminum spray coating.

[0067] The spray coating made of alumina clinker, mullite or corundum as aggregate and adding appropriate amount of zircon powder into the matrix (or small particles) is called aluminum zirconium spray coating. There are also silicon carbide spray coating, spinel spray coating, etc.

[0068] The binders used are: aluminate cement, phosphate, polyphosphate, metaphosphate, magnesium sulfate, magnesium chloride, sodium sulfate, sodium silicate and other materials. In order to obtain good construction performance, an appropriate amount of plastic clay is usually added. Compared with other amorphous refractory materials, the main differences are particle ratio, trace additives and water addition.

[0069] The physical and chemical indicators of refractory spray coating are as follows:

[0070]

[0071] According to the physical and chemical index chart of refractory spray coatings, we can see that the refractoriness of both FN-130 and FN-140 products is extremely high, reaching up to 1620°C. At the same time, their long-term refractory temperature is also around 1400°C. They are two products with excellent properties among refractory spray coating products.

[0072] This material has a certain plasticity and is in paste form. It is usually required to have high strength, excellent resistance to melt or gas erosion, good applicability and adhesion to the protected material, good thermal shock resistance and chemical stability, and no cracking, no peeling, and no chemical reaction with the parent material during use.

[0073] There are many types of refractory spray coatings with very different performances, but in general, we generally use it as a protective layer on the inner surface of blast furnaces and hot blast stove shells, as well as as a working lining for blast furnace heads, gas outlet pipes, and dust collectors.

[0074] The experimental results are shown in the following table:

[0075]

Qualitatively, a feed port 19 is provided on the upper side of the batching kettle 1, and the input end of the feed port 19 is connected to a feed hopper 4, and the top of the feed hopper 4 is connected to a discharge pipe 3, and a certain amount of various coatings are put into the discharge pipe 3, and the coating enters the feed port 19 along the feed hopper 4, and finally enters the batching kettle 1 along the feed port 19 for subsequent stirring and batching. A discharge port 20 is provided at the lower side of the batching kettle 1, and the output end of the discharge port 20 is connected to a discharge hopper 5, and the lower side of the discharge hopper 5 is connected to a recovery pipe 6, and the coating after stirring and batching is discharged along the discharge port 20, and finally reaches the recovery pipe 6 through the discharge hopper 5 for subsequent recovery treatment. Solenoid valves are provided inside the feed port 19 and the discharge port 20, and the solenoid valves are mainly used to regulate the on-off status of the feed port 19 or the discharge port 20.

[0077] A fixing frame 7 is provided on one side of the batching kettle 1, and a driving motor 8 is provided on the other end of the fixing frame 7. A driving wheel 9 is provided on the bottom output end of the driving motor 8. The controller controls the driving motor 8 to start and drive the driving wheel 9 to rotate. The bottom of the hydraulic telescopic rod 12 passes through the batching kettle 1 and is provided with a driven wheel 11. A conveyor belt 10 is provided on the outer surfaces of the driving wheel 9 and the driven wheel 11. The driving wheel 9 rotates and drives the conveyor belt 10 to rotate. The conveyor belt 10 rotates and drives the driven wheel 11 to rotate. The driven wheel 11 drives the hydraulic telescopic rod 12 to rotate. The hydraulic telescopic rod 12 rotates and drives the transmission shaft 13 on the top to rotate to stir and batch the paint.

[0078] When in use, first, the controller controls the solenoid valve at the end of the feed port 19 to open, and pours each coating into the feed hopper 4 along the discharge pipe 3 in turn, and enters the batching kettle 1 along the feed port 19 at the bottom of the feed hopper 4.

[0079] When the mixing and batching of the mixture is completed, the controller controls the solenoid valve in the discharge port 20 to open, and the paint inside the batching kettle 1 is continuously discharged along the discharge port 20, and enters the recovery pipe 6 through the discharge hopper 5 for recycling.

[0081] Second embodiment

[0082] like Figure 5-10As shown, in the prior art, when the transmission shaft 13 is used to drive the rotating shaft 21 to rotate and stir and mix the paint inside the batching kettle 1, the stirring efficiency is low and the stirring effect is poor, which cannot meet the actual processing requirements; and when the paint is fed into the batching kettle 1, since each paint is fed in sequence, different paints are easily stacked inside the batching kettle 1, and then the subsequent horizontal rotation of the rotating shaft 21 driven by the transmission shaft 13 cannot achieve uniform and thorough stirring and mixing of the paint; at the same time, when the paint is continuously added to the batching kettle 1, the height of the paint inside the batching kettle 1 is continuously increased, and if the height of the rotating shaft 21 does not change, the transmission shaft 13 cooperates with the rotating shaft 21 to rotate. The shaft 21 has a poor stirring and mixing effect on the paint inside the batching kettle 1; and the paint inside the batching kettle 1 will accumulate at some positions during stirring and mixing, and the accumulated paint cannot be quickly mixed only by the rotation of the rotating shaft 21, further reducing the effect of subsequent stirring and mixing; and when the stirring and mixing of the paint is completed, the mixture inside the batching kettle 1 needs to be discharged, but the gravity of the paint itself cannot achieve rapid discharge, and part of the mixture is easily attached to the inner wall of the batching kettle 1 and the inner wall of the discharge hopper 5, and the mixture accumulates and clogs inside the discharge hopper 5, making it impossible to discharge the subsequent mixture and reducing the stirring and mixing effect of the subsequent paint.

The outer surface of the sliding sleeve 14 is evenly provided with a plurality of L-shaped frames 16, and the bottom of the L-shaped frame 16 is provided with an annular gear frame 17.

The connecting shaft 23 rotates and drives the rotating tooth 24 to mesh with the annular gear frame 17 and drives the connecting shaft 23 to rotate. The rotation of the connecting shaft 23 drives the rotating shaft 21 to rotate around the transmission shaft 13. The rotating shaft 21 not only revolves inside the batching kettle 1, but also rotates itself, further improving the stirring and mixing effect of the rotating shaft 21 on the coating inside the batching kettle 1.

[0084] The interior of the rotating shaft 21 is uniformly arrayed with a plurality of through holes 42, and the interior of the through holes 42 is slidably connected with stirring blades 22, so that the stirring blades 22 can slide inside the through holes 42, thereby ensuring that the rotating shaft 21 drives the stirring blades 22 to rotate when it rotates, and the stirring blades 22 can exert a vertical stirring function on the paint inside the batching kettle 1 when it rotates, ensuring that the paint at the bottom of the batching kettle 1 can be turned upward, thereby improving the stirring and mixing effect of the paint inside the batching kettle 1, and the plurality of through holes 42 are spirally distributed vertically with each other, as shown in the figure, when the rotating shaft 21 rotates, the plurality of stirring blades 22 on the outer surface of the same rotating shaft 21 rotate in turn and vertically stir and mix the paint inside the batching kettle 1, so that the paint inside the batching kettle 1 can flow in any direction, further improving the irregularity and thoroughness of the stirring and mixing.

[0085] A groove 25 is provided at the top of the middle through hole 42, and an upper plate 26 is provided inside the groove 25. The bottom of the upper plate 26 is fixedly connected to the top of the stirring blade 22. The size of the groove 25 matches the size of the upper plate 26. The groove 25 and the upper plate 26 cooperate and limit the stirring blade 22 to prevent the stirring blade 22 from sliding out along the middle through hole 42. At the same time, when the upper plate 26 is located inside the groove 25, the outer surface of the rotating shaft 21 is still a smooth curved surface, further improving the scraping and cleaning effect of the inner wall of the batching kettle 1.

[0086] A bottom plate 28 is provided at the bottom of the stirring blade 22, and a plurality of pulse holes 40 are evenly provided inside the bottom plate 28. A one-way exhaust valve 41 is provided inside the pulse hole 40. Then, the gas inside the pulse hole 40 is continuously discharged along the one-way exhaust valve 41 in pulses, which not only cooperates with the stirring blade 22 in the vertical direction to improve the irregular mixing effect of the paint inside the batching kettle 1, but also improves the subsequent feeding efficiency of the paint along the discharge port 20, and avoids the adhesion of part of the mixture between the inner wall of the batching kettle 1 and the inside of the discharge hopper 5 and affects the stirring and mixing of the subsequent paint. A bottom groove 51 is provided at the bottom of the through hole 42, and the size of the bottom groove 51 matches the size of the bottom plate 28. Similarly, the bottom groove 51 cooperates with the bottom plate 28 and limits the stirring blade 22, so that when the bottom plate 28 reaches the inside of the bottom groove 51, the outer surface of the rotating shaft 21 is a smooth curved surface, thereby improving the scraping and cleaning effect of the inner wall of the batching kettle 1.

[0087] An elastic sleeve 27 is provided at the bottom of the bottom groove 51 and on both sides of the stirring blade 22. Gas is stored in the elastic sleeve 27. A connecting hole 36 is provided between the elastic sleeve 27 and the pulse hole 40. When the elastic sleeve 27 is squeezed, the internal gas enters the pulse hole 40 along the connecting hole 36 and is discharged to both sides of the bottom plate 28 along the one-way exhaust valve 41 inside the pulse hole 40, further improving the stirring and mixing effect of the coating inside the batching kettle 1. A side groove 37 is provided on one side of the connecting hole 36. A blocking plate 39 is slidably connected inside the side groove 37. The blocking plate 39 blocks the connecting hole 36. When the blocking plate 39 moves along the side groove 37 and opens the connecting hole 36, the gas inside the elastic sleeve 27 can The elastic sleeve 27 is arranged in a horizontal direction with respect to the rotation shaft 21, and the stirring blade 22 is driven to rotate when the rotation shaft 21 rotates. The front and rear ends of the stirring blade 22 are squeezed and contacted with the coating inside the batching kettle 1. Since the elastic sleeve 27 is parallel to the axis of the rotation shaft 21, the elastic sleeve 27 will not be squeezed by the coating inside the batching kettle 1. The deformation of the elastic sleeve 27 is only related to the movement of the bottom plate 28. An inner cavity spring 35 is arranged at the bottom of the bottom groove 51. The bottom of the inner cavity spring 35 is fixedly connected with the top of the bottom plate 28. The inner cavity spring 35 is arranged inside the elastic sleeve 27. The arrangement of the inner cavity spring 35 further improves the elastic reset performance of the bottom plate 28.

[0088] A plurality of air inlet holes 29 are evenly arranged on the top of the bottom groove 51. The air inlet holes 29 are mainly used to replenish air inside the elastic sleeve 27. The bottom of the air inlet hole 29 is connected to the top of the elastic sleeve 27, and the top of the air inlet hole 29 is connected to the bottom of the groove 25. Then, the gas inside the groove 25 enters the elastic sleeve 27 along the air inlet hole 29 for air replenishment. A one-way air inlet valve 30 is arranged inside the air inlet hole 29. The air inlet direction of the one-way air inlet valve 30 is from the end of the groove 25 to the end of the elastic sleeve 27, and the exhaust direction of the one-way exhaust valve 41 is from the end of the pulse hole 40 to the outside. With the arrangement of the one-way air inlet valve 30 and the one-way exhaust valve 41, the unidirectionality of the gas circulation is further improved to prevent the paint inside the batching kettle 1 from polluting the internal structure in the reverse direction.

[0089] The dimensions of the two sides of the middle through hole 42 parallel to the elastic sleeve 27 are the same as the dimensions of the stirring blade 22, and the dimensions of the two sides of the middle through hole 42 perpendicular to the elastic sleeve 27 are larger than the dimensions of the stirring blade 22. This arrangement ensures that when the stirring blade 22 rotates inside the middle through hole 42, it will not shake in the left and right directions, but will move in the front and back directions due to the squeezing of the paint inside the batching kettle 1, thereby improving the stability of the stirring blade 22 moving inside the middle through hole 42 and the stirring and mixing effect on the paint.

[0090] Two slots 43 are symmetrically provided on both sides of the through hole 42 near the stirring blade 22. The slots 43 are slidably connected with an insertion rod 44. When the stirring blade 22 is blocked by the paint and the insertion rod 44 is squeezed accordingly, the insertion rod 44 moves inside the slot 43 and squeezes the gas inside the slot 43. A top hole 46 is provided on the top of the slot 43. A push rod 48 is slidably connected inside the top hole 46. The top of the push rod 48 is in contact with the bottom of the upper plate 26. Then the corresponding gas inside the slot 43 enters the bottom of the top hole 46 upward, the internal air pressure of the top hole 46 increases and drives the push rod 48 to move upward along the top hole 46, and the push rod 48 drives the upper plate 26 to break away from the groove 25 and move upward.

[0091] The outer surface of the top rod 48 is sealed and slidably connected to the inner wall of the top hole 46, and the side wall of the slot 43 is provided with a transverse spring 45. The other end of the transverse spring 45 is fixedly connected to the side wall of the insertion rod 44. The outer surface of the insertion rod 44 is sealed and slidably connected to the inner wall of the slot 43. The provision of the transverse spring 45 further improves the elastic reset performance of the insertion rod 44.

[0092] A matching groove 31 is provided at the bottom of the groove 25, and the matching groove 31 is at the same position as the elastic sleeve 27. A bellows 32 is provided at the inner bottom of the matching groove 31. An air guide hole 34 is provided inside the stirring blade 22. The inside of the bellows 32 is connected with the air guide hole 34. When the upper plate 26 moves upward, the bellows 32 is stretched, the volume of the bellows 32 increases, and the air pressure decreases. Then, under the negative pressure of the bellows 32 itself, the gas inside the air guide hole 34 is extracted and reversely enters the inside of the bellows 32. The other end of the air guide hole 34 passes through the bottom plate 28 and is connected with the side groove 37 through the docking hole 50. Then, the air guide hole 34 extracts the gas inside the side groove 37 along the docking hole 50 to enter the inside of the air guide hole 34. The air pressure inside the side groove 37 decreases and the blocking plate 39 is correspondingly extracted to squeeze the reset spring 38 to move toward the inside of the side groove 37. The blocking area of ​​the blocking plate 39 to the connecting hole 36 is reduced, and the gas inside the elastic sleeve 27 can enter the pulse hole 40 along the connecting hole 36.

[0093] A connecting spring 33 is provided at the inner bottom of the matching groove 31, and the top of the connecting spring 33 is fixedly connected to the bottom of the upper plate 26. The setting of the connecting spring 33 further improves the elastic reset performance of the upper plate 26. A reset spring 38 is provided on one side of the side groove 37, and the other end of the reset spring 38 is fixedly connected to the side wall of the blocking plate 39. The setting of the reset spring 38 improves the elastic reset performance of the blocking plate 39. The outer surface of the blocking plate 39 is sealingly and slidingly connected to the inner wall of the side groove 37, and the blocking plate 39 matches the connecting hole 36. This setting further improves the sealing and blocking performance of the blocking plate 39 on the connecting hole 36, thereby correspondingly adjusting the amount of gas inside the elastic sleeve 27 entering the pulse hole 40 along the connecting hole 36, and using this gas amount to correspondingly adjust the gas mixing effect on the paint inside the batching kettle 1 and the pulse impact cleaning effect on the inner wall of the batching kettle 1 and the discharge port 20 end.

[0094] The bottoms of the two sides of the groove 25 and the elastic sleeve 27 that are perpendicular to each other are provided with a clearance groove 47, and the inner bottom of the clearance groove 47 is provided with an ejection spring 49, the top of the ejection spring 49 is fixedly connected to the bottom of the upper plate 26, and the ejection spring 49 is located on the outer surface of the ejector rod 48. This arrangement further improves the elastic reset performance of the upper plate 26, thereby ensuring the synchronization and stability of the movement of the ejector rod 48 and the upper plate 26.

[0095] When in use, the device is installed according to the first embodiment. At this time, the output end of the hydraulic telescopic rod 12 is at the lowest value, and the corresponding output end of the hydraulic telescopic rod 12 drives the transmission shaft 13 to move downward to the maximum distance. The multiple self-rotating shafts 21 on the outer surface of the transmission shaft 13 are squeezed and contacted with the bottom of the batching kettle 1, and then the paint is poured into the feed hopper 4 along the discharge pipe 3. The paint falls into the batching kettle 1 along the feed port 19. At this time, the distance value detected by the distance sensor 18 near the feed port 19 increases, and the controller controls the drive motor 8 to start and drive the driving wheel 9 to rotate. The driving wheel 9 drives the driven wheel 11 to rotate through the conveyor belt 10, and the driven wheel 11 drives the hydraulic telescopic rod 12 to rotate. The hydraulic telescopic rod 12 drives the self-rotating shaft 21 to rotate through multiple sets of transmission shafts 13. The self-rotating shaft 21 spreads the paint accumulated at the bottom of the batching kettle 1 to avoid the accumulation of paint at the feed port 19 and reduce the subsequent stirring and mixing effect of the paint.

[0096] As the paint continuously enters the batching kettle 1 along the feed port 19, the amount of paint inside the batching kettle 1 continues to increase, and the corresponding paint height inside the batching kettle 1 continues to rise, then the distance value detected by the corresponding distance sensor 18 continues to decrease, and the controller controls the output end of the hydraulic telescopic rod 12 to continuously extend, and the output end of the hydraulic telescopic rod 12 continuously drives the transmission shaft 13 to move upward, and the transmission shaft 13 drives multiple rotation shafts 21 to continuously move upward, then the bottom of the rotation shaft 21 is on the same horizontal plane as the top of the paint, and the continuous stirring action of the rotation shaft 21 makes the paint inside the batching kettle 1 continuously spread, thereby improving the subsequent stirring and mixing effect of the paint.

[0097] And the rotating shaft 21 revolves around with the rotation of the transmission shaft 13, and the rotating shaft 21 drives the rotating teeth 24 to revolve synchronously through the connecting shaft 23. At the same time, the rotating teeth 24 are meshed with the annular gear rack 17 and drive the rotating teeth 24 to rotate themselves. The rotation of the rotating teeth 24 synchronously drives the rotating shaft 21 to rotate through the connecting shaft 23. The rotation of the rotating shaft 21 drives the stirring blades 22 to rotate synchronously. The stirring blades 22 stir the paint vertically and cooperate with the revolution of the rotating shaft 21, so as to further improve the stirring and mixing effect of the paint.

[0098] And during the rotation of the stirring blade 22, when the stirring blade 22 continuously rotates upward along the top of the rotation shaft 21, one side of the stirring blade 22 first comes into squeeze contact with the paint. At this time, the paint exerts a reverse force on the stirring blade 22, and the stirring blade 22 simultaneously drives the paint to move and mix in the vertical direction. Since the force exerted by the paint on the stirring blade 22 is relatively small at this time, the insertion rod 44 will not move under the elastic force of the transverse spring 45 inside the slot 43, and the stirring blade 22 can stir and push the paint in the vertical direction.

[0099] When the stirring blade 22 rotates continuously and drives the bottom of the bottom plate 28 and the bottom of the batching kettle 1 to be squeezed and contacted with each other, the stirring blade 22 squeezes the insertion rod 44 with the help of the force applied to the stirring blade 22 by the bottom of the batching kettle 1, and the insertion rod 44 squeezes the transverse spring 45 inside the slot 43 and moves inward, and the insertion rod 44 squeezes the internal gas of the slot 43 and makes it enter the top hole 46, and the internal air pressure of the top hole 46 increases and drives the ejector rod 48 to move upward, and the top of the ejector rod 48 and the bottom of the upper plate 26 are squeezed and contacted with each other and drive the upper plate 26 to stretch and eject the spring 49 to move upward, and when the upper plate 26 moves, it drives the stirring blade 22 to move upward along the middle through hole 42, and the bottom plate 28 at the bottom of the stirring blade 22 moves upward, and the bottom plate 28 and the bottom of the batching kettle 1 are separated from the squeeze contact with each other, further avoiding that the stirring blade 22 and the bottom of the batching kettle 1 are stopped when the rotation shaft 21 rotates, thereby reducing the stirring and mixing effect of the stirring blade 22 on the coating inside the batching kettle 1.

[0100] When the upper plate 26 moves upward, the bellows 32 is stretched synchronously, the volume of the bellows 32 increases and the internal pressure decreases, then the bellows 32 applies suction force to the air guide hole 34, and the air guide hole 34 draws the internal gas of the side groove 37 along the docking hole 50 into the air guide hole 34 under the action of negative pressure, the internal air pressure of the side groove 37 is reduced and drives the blocking plate 39 to squeeze the reset spring 38 and move in the opposite direction, the blocking area of ​​the connecting hole 36 by the blocking plate 39 is reduced, and the internal gas of the elastic sleeve 27 enters the pulse hole 40 along the connecting hole 36, and the internal gas of the pulse hole 40 is discharged to both sides along the one-way exhaust valve 41, and then the left and right sides of the paint are blown and mixed by wind, and the pushing effect of the stirring blade 22 on the front and rear directions of the paint is effectively improved, the stirring effect is better, and the mixing efficiency is higher.

[0101] As the rotating shaft 21 continues to rotate, the rotating shaft 21 drives the stirring blade 22 to continue to rotate. Since the bottom of the batching kettle 1 is a horizontal surface, the bottom of the bottom plate 28 is constantly squeezed and contacted with the inner bottom of the batching kettle 1. The bottom plate 28 drives the stirring blade 22 to continue to move upward along the middle through hole 42. The bottom plate 28 continuously squeezes the elastic sleeve 27 upward, and the blocking plate 39 moves along the side groove 37 to increase the opening area of ​​the connecting hole 36. The amount of gas inside the elastic sleeve 27 entering the pulse hole 40 along the connecting hole 36 increases, and the amount of gas discharged to both sides of the pulse hole 40 through the one-way exhaust valve 41 increases, further improving the stirring and mixing effect of the coating. When the stirring blade 22 reaches the vertical state, the bottom plate 28 drives the stirring blade 22 to reach the maximum extent, the elastic sleeve 27 is squeezed to the maximum extent, and the amount of gas discharged to both sides of the elastic sleeve 27 along the connecting hole 36 and the pulse hole 40 reaches the maximum.

[0102] Afterwards, when the rotating shaft 21 drives the stirring blade 22 to continue to rotate, the stirring blade 22 drives the bottom plate 28 to continuously break away from the squeezed state with the bottom of the batching kettle 1, and the squeezing force applied by the stirring blade 22 to the insertion rod 44 is continuously reduced, and the insertion rod 44 is driven to move in the opposite direction under the elastic force of the transverse spring 45, and the internal space of the slot 43 is increased, then the corresponding bottom air pressure in the top hole 46 is reduced and drives the ejector rod 48 to move downward, and the supporting force applied by the ejector rod 48 to the bottom of the upper plate 26 is reduced, and the upper plate 26 is driven to move downward under the elastic force of the ejection spring 49, and at the same time, the tension applied by the upper plate 26 to the bellows 32 is reduced, and the bellows 32 moves downward and the volume is reduced, then the gas inside the bellows 32 is discharged along the air guide hole 3 4 and the docking hole 50 enter the side groove 37, and under the action of air pressure, the blocking plate 39 is driven to move and continuously block the connecting hole 36. At the same time, since the upper plate 26 continuously drives the stirring blade 22 to move downward, the stirring blade 22 moves downward through the bottom plate 28, and the bottom plate 28 stretches the elastic sleeve 27. The volume of the elastic sleeve 27 increases and applies suction force, so that the gas inside the groove 25 enters the inside of the air inlet hole 29 along the one-way air inlet valve 30, and finally enters the inside of the elastic sleeve 27 along the air inlet hole 29 for air replenishment. At this time, since the bottom of the stirring blade 22 is parallel to the top of the coating, the groove 25 is located at the top of the coating, so the coating will not enter the inside of the groove 25 and hinder the air intake of the air inlet hole 29.

[0103] As the stirring and mixing of the paint continues, the height of the paint inside the batching kettle 1 continues to rise to the maximum distance. At this time, the distance value detected by the distance sensor 18 continues to increase to the maximum distance. The corresponding controller controls the hydraulic telescopic rod 12 to continuously drive the transmission shaft 13 to move upward to the maximum distance. The transmission shaft 13 drives the sliding sleeve 14 to move upward along the sliding rod 15 to the maximum distance. The sliding sleeve 14 drives the annular gear rack 17 to move upward to the maximum distance through the L-shaped frame 16. The bottom of the annular gear rack 17 and the top of the rotating tooth 24 are always in a mutually meshing state to the maximum distance, further improving the rotation effect of the rotating shaft 21, and the above process is continuously repeated to achieve the stirring and mixing effect inside the batching kettle 1. Therefore, even if the amount of paint inside the batching kettle 1 is different, the bottom of the rotating shaft 21 can still always remain parallel to the top of the paint, the stirring blade 22 thoroughly and effectively stirs and mixes the paint inside the batching kettle 1 vertically, and the amount of gas discharged from the pulse hole 40 is correspondingly mixed by wind, which has stronger adaptability and better mixing effect.

[0104] After the mixing of the coating is completed, the controller opens the solenoid valve inside the discharge port 20. At this time, the mixture inside the batching kettle 1 enters the recovery pipe 6 through the discharge hopper 5 along the discharge port 20. The distance value detected by the distance sensor 18 continues to decrease, and the controller controls the output end of the hydraulic telescopic rod 12 to drive the transmission shaft 13 to continue to move downward. At the same time, the transmission shaft 13 drives the revolution of the rotation shaft 21 in the opposite direction to the rotation direction of the rotation shaft 21 itself. When the rotation shaft 21 drives the stirring blade 22 to rotate, it applies a thrust to the coating, thereby improving the stability and efficiency of the coating inside the batching kettle 1 entering the discharge hopper 5 along the discharge port 20. As the coating inside the batching kettle 1 is continuously discharged, when the bottom plate 28 and the bottom of the batching kettle 1 are squeezed and contacted with each other, the gas inside the elastic sleeve 27 is discharged along the pulse hole 40. With the help of the gas, a pulse force is effectively applied to the coating, thereby improving the pulse falling efficiency of the coating entering the discharge hopper 5 along the discharge port 20, ensuring that the coating falls stably and efficiently, with stronger adaptability and higher stability.

[0105] When the coating inside the batching kettle 1 enters the discharge hopper 5 along the discharge port 20, the mixture on the inner wall of the batching kettle 1 is scraped off by the continuous rotation of the rotating teeth 24, and the mixture at the bottom of the batching kettle 1 needs to be further scraped off. At this time, the distance value detected by the distance sensor 18 reaches the maximum value, and the controller controls the output end of the hydraulic telescopic rod 12 to drive the transmission shaft 13 to move downward to the maximum distance, and the transmission shaft 13 drives the rotation shaft 21 to move downward to the maximum distance and squeeze and contact with the bottom of the batching kettle 1. At this time, the revolution direction and the rotation direction of the rotation shaft 21 are opposite. For example, when the rotation shaft 21 rotates clockwise around the transmission shaft 13, the rotation shaft 21 on the left side rotates counterclockwise when viewed from the right side, and the rotation shaft 21 applies a scraping force to the bottom of the batching kettle 1, further improving the scraping and cleaning effect of the mixture at the bottom of the batching kettle 1, and when the rotation shaft 21 rotates and drives the stirring blade 22 to rotate and squeeze and contact with the bottom of the batching kettle 1, it can be known from the above The plate 26 drives the stirring blade 22 to move upward rapidly along the middle through hole 42, and the stirring blade 22 drives the bottom plate 28 to move upward, and the bottom plate 28 squeezes the elastic sleeve 27. At the same time, since the upper plate 26 moves upward to the maximum distance, the volume of the bellows 32 expands to the maximum distance. Under the air guiding action of the air guiding hole 34, the blocking plate 39 moves to the maximum distance along the side groove 37, and the blocking plate 39 no longer blocks the connecting hole 36. The gas inside the elastic sleeve 27 quickly enters the pulse hole 40 along the connecting hole 36, and the amount of gas discharged along the pulse hole 40 increases continuously, and cooperates with the rotation of the rotating shaft 21 itself to further improve the scraping effect of the pulse hole 40 on the bottom coating in the batching kettle 1. At the same time, the gas reaches the inside of the discharge hopper 5 along the discharge port 20, and the impact of the gas is used to ensure the circulation stability of the coating inside the discharge hopper 5 and the cleanliness of the inner wall. When the rotating shaft 21 rotates to the maximum angle, the bottom plate 28 enters the bottom groove 51, and thus will not hinder the rotation of the rotating shaft 21 itself.

[0106] After the mixture inside the batching kettle 1 is discharged, the controller controls the electromagnetic valve inside the discharge port 20 to close, and re-feeds new paint into the feed hopper 4 along the discharge pipe 3, and the above process is repeated continuously to continue stirring and mixing the subsequent paint.

[0107] The device effectively improves the stirring and mixing effect of the paint, ensures that the paint can be evenly and thoroughly batched, has higher batching precision and better batching accuracy, and in the batching process, not only the horizontal rotation mixing of the paint inside the batching kettle 1 is achieved, but also the stirring and mixing of the paint in the vertical direction is achieved when the stirring blade 22 rotates, and the stirring is more thorough; and when the stirring blade 22 stirs the paint, the gas ejected from the pulse hole 40 is cooperated to effectively improve the irregular mixing effect of the paint inside the batching kettle 1, and the adaptability is stronger and the stability is higher; and when the height of the paint inside the batching kettle 1 changes continuously, by adjusting the height of the transmission shaft 13, not only the precise stirring and mixing of the paint is achieved, but also the amount of gas ejected from the pulse hole 40 can be adjusted, thereby ensuring the stirring and mixing effect of the paint; after the stirring and mixing of the paint inside the batching kettle 1 is completed, the inner wall of the batching kettle 1 can be thoroughly and effectively scraped and cleaned, and the discharge port 20 and the discharge hopper 5 are cleared by gas pulse impact, so that the cleaning performance is higher and the dredging performance is better.
