Description

Technical Field

[0001] The invention relates to the technical field of insulating varnish production, in particular to integrated production equipment for polyurethane insulating varnish. Background Art

[0002] Polyurethane insulating paint is a highly efficient, corrosion-resistant and anti-oxidation insulating coating, mainly composed of polyurethane resin, solvent, filler, additives, etc. The main component of polyurethane insulating paint is polyurethane resin, which is a macromolecular long-chain compound formed by the reaction and polymerization of isocyanate groups and hydroxyl compounds, while solvents and additives are used to adjust the viscosity, fluidity and other properties of the paint, and ensure its stability and film-forming quality during the construction process;

[0003] The production process of polyurethane insulating paint mainly includes the steps of raw material preparation, mixing, grinding, dispersing, filtering, adjusting, and packaging. First, select the corresponding raw materials and proportion them; then add the raw materials into the mixing tank in turn and mix them thoroughly through the stirring equipment. As a kind of polymer, polyurethane has the characteristics of being intolerant to strong polar solvents and strong acid and alkali media. In the process of producing insulating paint, the molecular structure of the selected mixed solvent is similar to that of polyurethane, which can penetrate between polyurethane molecules and destroy its structure, resulting in changes in the physical and chemical properties of polyurethane, which will cause the polyurethane to swell. Then, put the mixed swelling material into the grinder, and further refine the solid particles through the action of friction and shear force to increase the fluidity and glossiness of the coating. Then, pass the ground swelling material through the filtering device to remove impurities and particles therein, so that the coating has better transparency and flatness. Then, according to the use requirements of the product, add appropriate amount of additives, such as antioxidants, ultraviolet absorbers, etc., to improve the weather resistance and anti-aging properties of the coating. Finally, package the produced insulating paint.

[0004] In the production of polyurethane insulating varnish, in order to reduce the time consumed in the transfer of raw materials, integrated production equipment is usually used to process the insulating varnish, and the mixing area is set above the grinding area. Since the raw materials are in fluid form and have fluidity, the driving source for injection can also be saved. During production, when the raw materials are not mixed evenly, the raw materials are easy to flow from the mixing area to the grinding area. Therefore, it is necessary to set a valve to block it during the production process. After mixing, the valve is opened to inject the mixed raw materials into the grinding area. When too much raw material is injected into the grinding area at one time, raw material blockage is likely to occur. At the same time, the pressure of the raw materials in the grinding area becomes greater, and the raw materials are easily squeezed out of the grinding tank, affecting the quality of grinding. Injection is performed by controlling the intermittent opening and closing of the valve, which increases the number of times the valve is opened and closed in a short period of time, which is easy to cause damage to the valve and affect the processing efficiency.

[0005] Therefore, an integrated production equipment for polyurethane insulating varnish is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide an integrated production equipment for polyurethane insulating varnish, which grinds the raw material by driving the connecting shaft to rotate, and makes the mixing component reciprocate up and down in the second mixing chamber during grinding, thereby improving the mixing effect and preliminarily crushing the raw material. The connecting shaft can also drive the conical disk to separate intermittently from the side wall at the bottom of the second mixing chamber, intermittently feed the grinding component, relieve the pressure on the top of the grinding component, and ensure the quality of grinding while improving the integrated production efficiency of the insulating varnish.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] An integrated production equipment for polyurethane insulating paint comprises a tank body, wherein the tank body is provided with a discharge pipe, a heater, a plurality of storage tanks, a quantitative valve at the bottom of the storage tanks and a feeding pipe, wherein the specific number of the storage tanks can be selected according to the types of raw materials of different formulas in the batching process, and the quantitative valve realizes the quantitative injection of the raw materials, thereby improving the batching efficiency, a filter screen is inserted in the discharge pipe, and a first mixing chamber, a grinding tank and a second mixing chamber are sequentially opened in the tank body from bottom to top, a mixing component is arranged in the second mixing chamber, a grinding component is arranged in the grinding tank, and the The central axes of the mixing assembly and the grinding assembly are both located at the axis center of the tank body. The grinding assembly includes a connecting shaft rotatably installed at the center of the tank body, and the connecting shaft is located on the inner side of the mixing assembly. During operation, the grinding assembly drives the mixing assembly to slide back and forth up and down in the second mixing chamber. A conical disk is also fixedly installed on the outer side of the connecting shaft. When the connecting shaft is stationary, the conical disk is in contact with the bottom end of the second mixing chamber and seals the second mixing chamber. During the rotation of the connecting shaft, the conical disk is intermittently separated from the side wall of the bottom end of the second mixing chamber and intermittently feeds the grinding assembly.

[0009] Through the above scheme, according to the characteristic that the fluid will flow downward under the action of its own gravity, during the processing, the insulating paint raw materials are gradually flowed from the second mixing chamber to the grinding trough and the first mixing chamber, thereby achieving the continuity of processing. When the grinding component is not working, the conical disk will seal the second mixing chamber, and the mixing component can ensure that the raw materials are mixed evenly. When the grinding component is running, the rotation of the connecting shaft will cause the mixing component to reciprocate up and down in the second mixing chamber, and at the same time, it can also drive the conical disk and the side wall of the bottom end of the second mixing chamber to be intermittently separated, thereby improving the mixing effect and being able to intermittently feed the grinding component, thereby achieving efficient linkage between grinding and mixing.

[0010] Preferably, the mixing assembly includes a first driven bevel gear, a fixed sleeve, a movable sleeve, a first mixing blade and a mixing head, the first driven bevel gear is fixedly mounted on the top end of the fixed sleeve, the movable sleeve is inserted in the fixed sleeve, a hexagonal groove is provided at the bottom end of the fixed sleeve, a hexagonal cylinder matching the hexagonal groove is fixedly mounted on the top end of the movable sleeve, a circular ring is rotatably mounted on the top end of the hexagonal cylinder, the fixed sleeve, movable sleeve, hexagonal cylinder and circular ring are all sleeved on the outside of the connecting shaft, a reciprocating thread groove is provided on the outer wall of the connecting shaft located in the fixed sleeve, and a convex ring matching the reciprocating thread groove is fixedly mounted on the inner wall of the circular ring.

[0011] Through the above scheme, when the connecting shaft rotates, the reciprocating threaded groove on the side wall of the top end of the connecting shaft cooperates with the convex ring in the circular ring, so that the movable sleeve can slide back and forth up and down in the fixed sleeve, further improving the mixing effect. The hexagonal cylinder and the hexagonal groove arranged in a hexagonal shape ensure that the movable sleeve can slide stably at the bottom end of the fixed sleeve, and the circular ring rotatably installed on the top end of the hexagonal cylinder will idle at the top end of the hexagonal cylinder when the connecting shaft does not rotate, thereby avoiding obstruction to the operation of the mixing component.

[0012] Preferably, the bottom end of the second mixing chamber is configured to be conical, the first mixing blade is fixedly mounted on the outside of the movable sleeve, the bottom wall and side walls of the first mixing blade are made of rubber material, and the bottom wall and side walls of the first mixing blade are in contact with the bottom wall and side walls of the second mixing chamber.

[0013] Through the above scheme, the outer wall is made of rubber material, which can improve the flexibility of the first mixing blade, and the first mixing blade can scrape the raw materials on the side wall of the second mixing chamber during the reciprocating movement of the movable sleeve up and down, thereby preventing the insulating paint from solidifying and forming on the side wall of the second mixing chamber.

[0014] Preferably, the mixing head is fixedly mounted on the bottom end of the movable sleeve, a plurality of small blades are evenly fixedly mounted on the top end of the mixing head, an impeller is fixedly mounted on the bottom end of the mixing head, and the gap between the outer walls of the impeller and the small blades and the inner wall of the bottom end of the first mixing blade is 2 cm.

[0015] Through the above solution, the 2 cm gap can provide a safe space for the impeller and the small blades, facilitate the flow of raw materials in the gap, and avoid the first mixing blade from hindering the high-speed shearing of the impeller and the small blades.

[0016] Optionally, the small blades and impellers on the mixing head can be set to large sizes. However, due to high-speed rotation, large-sized blades and impellers increase their contact area with the raw materials during the mixing process, further increasing the resistance during the rotation of the blades and impellers, which will increase the load on the motor and affect the service life of the motor. Therefore, small blades and impellers of smaller sizes are selected.

[0017] Preferably, the grinding assembly also includes a plurality of grinding heads, a grinding base, a second mixing blade and a second driven bevel gear. The grinding base is rotatably installed in the grinding groove, and the central axis of the grinding base is fixedly connected to the central axis of the connecting shaft. The plurality of grinding heads are evenly and fixedly installed on the outside of the grinding base, and the grinding heads are all embedded in the grinding groove. The second driven bevel gear is vertically slidably installed on the top end of the connecting shaft. The second mixing blade is located on the outer wall of the bottom end of the connecting shaft. The outer wall of the second mixing blade is made of rubber material. The outer wall of the second mixing blade is tightly fitted with the inner wall of the first mixing chamber. The side wall of the top end of the second mixing blade is inclined inward, and the bottom end of the second mixing blade is fitted with the top wall of the filter.

[0018] Through the above scheme, the second mixing blade can stir and mix the raw materials ground in the first mixing chamber while the grinding head rotates, and the second mixing blade can push the particles intercepted on the filter to move, avoiding clogging of the filter, thereby improving the production rate of the product, while ensuring the filtering effect and the quality of the product.

[0019] Preferably, the specific number of the grinding heads is three, and the grinding accuracy of the three grinding heads increases from top to bottom, and the top of the grinding base is provided with a chamfer.

[0020] Through the above scheme, the chamfer setting provides a certain feeding space for the grinding component, and the accuracy of the grinding head is gradually increased, ensuring the grinding effect.

[0021] Preferably, the top end of the conical disk is arranged in an inclined arc shape from the inside to the outside, and a plurality of small convex balls are evenly and fixedly mounted on the arc surface of the top end of the conical disk.

[0022] Through the above scheme, the inclined arc surface helps the fluid to move from the middle position of the conical disk to the outside, avoiding the raw material from remaining on the conical disk. The small convex balls change the splashing direction of the raw material when the impeller pushes the raw material to contact the conical disk, further improving the mixing effect.

[0023] Preferably, two arc grooves are symmetrically opened at the bottom end of the conical disk, and an arc slide rail matching the arc groove is fixedly installed at the edge position of the bottom end of the second mixing chamber, and the length of a single arc slide rail is one tenth of the circumference of the bottom end of the second mixing chamber.

[0024] Through the above scheme, during the rotation of the conical disk, the arc groove can be separated from the arc slide rail for a certain period of time, thereby realizing intermittent feeding of the grinding assembly and alleviating the pressure on the bottom end of the grinding assembly.

[0025] Preferably, a motor and a hydraulic telescopic rod are fixedly installed on the top of the tank body, the output end of the motor is fixedly connected to a driving bevel gear, the extended end of the hydraulic telescopic rod is fixedly connected to a connecting frame, and the top end of the second driven bevel gear is rotatably mounted on the bottom wall of the connecting frame.

[0026] Through the above scheme, the height of the second driven bevel gear can be adjusted by the hydraulic telescopic rod to achieve the engagement and separation of the second driven bevel gear and the active bevel gear, thereby ensuring that the grinding assembly is in a stopped state during the mixing process, which is conducive to the full mixing of the raw materials.

[0027] Preferably, the front end of the active bevel gear teeth meshes with the first driven bevel gear, the rear end of the active bevel gear teeth meshes with the second driven bevel gear, and the transmission ratio of the first driven bevel gear to the second driven bevel gear is eight to one.

[0028] Through the above scheme, the driving bevel gear meshes with the first driven bevel gear and the second driven bevel gear at different positions of the teeth, and the speed ratio between the first driven bevel gear and the second driven bevel gear is adjusted, so that the mixing component can mix quickly while grinding slowly.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. By setting the grinding assembly and the conical disc, when the grinding assembly is running, the connecting shaft can drive the conical disc to rotate synchronously. At this time, the arc groove can be separated from the arc slide rail for a certain period of time, so that the bottom wall of the conical disc and the side wall of the bottom end of the second mixing chamber are intermittently separated, which facilitates the mixed raw materials to enter the grinding groove, realizes intermittent feeding of the grinding assembly, relieves the pressure on the top of the grinding assembly, and ensures the grinding effect while improving the integrated production efficiency of the insulating paint.

[0031] 2. By setting up a stirring component and a conical disk, during the process of the mixing component mixing the raw materials, the conical disk can seal the second mixing chamber to prevent unmixed raw materials from entering the grinding tank, so that the raw materials can be fully mixed and the mixing effect can be guaranteed. In addition, the small convex balls change the sputtering direction of the raw materials during the process of the impeller pushing the raw materials to contact the conical disk, further improving the mixing effect and ensuring the integrated production efficiency of the insulating paint.

[0032] 3. By setting up a stirring component and a grinding component, when the grinding component is not working, the mixing component can ensure that the raw materials are mixed evenly. When the grinding component is running, the continuous rotation of the connecting shaft will cause the mixing component to move up and down in the second mixing chamber, which can change the activity range of the small blades and impellers on the mixing head, and can improve the mixing effect. The high-speed rotating small blades and impellers can perform preliminary shearing on the raw materials in the second mixing chamber, which can reduce the grinding difficulty of the grinding component and reduce the wear of the grinding component. The impeller at the bottom of the mixing head can push the raw materials downward during high-speed rotation, and can provide a certain thrust for the raw materials at the bottom to enter the grinding component, which is conducive to the rapid loading of the grinding component.

[0061] In this embodiment, the height of the second driven bevel gear 506 can be adjusted by the hydraulic telescopic rod 3 to achieve the engagement and separation of the second driven bevel gear 506 and the active bevel gear 201. When the second driven bevel gear 506 is separated from the active bevel gear 201, the mixing component 4 operates normally and the grinding component 5 is in a stopped state, which is conducive to the full mixing of the raw materials. When the second driven bevel gear 506 is engaged with the active bevel gear 201, the mixing component 4 and the grinding component 5 operate simultaneously, so that the polyurethane insulating paint can be processed quickly.

[0062] As an embodiment of the present invention, refer to Figure 4The front end of the active bevel gear 201 is meshed with the first driven bevel gear 401, and the rear end of the active bevel gear 201 is meshed with the second driven bevel gear 506, and the transmission ratio of the first driven bevel gear 401 to the second driven bevel gear 506 is eight to one.

[0063] In this embodiment, the driving bevel gear 201 meshes with the first driven bevel gear 401 and the second driven bevel gear 506 at different positions of the teeth, thereby adjusting the speed ratio between the first driven bevel gear 401 and the second driven bevel gear 506, so that the mixing component 4 can mix materials quickly while grinding slowly.

[0064] Working principle: First, the proportioned raw materials are injected into the second mixing chamber 107 in the tank body 1 through the storage chamber 103 in conjunction with the quantitative valve 1031, and then the heater 102 is started, and then the motor 2 is started, and the motor 2 drives the active bevel gear 201 to rotate. At this time, the first driven bevel gear 401 meshed with the active bevel gear 201 rotates at the same time, and the fixed sleeve 402 and the movable sleeve 403 clamped at the bottom of the fixed sleeve 402 can rotate at the same time. At this time, the impeller 4052 and the small blade 4051 on the mixing head 405 at the bottom of the movable sleeve 403 can mix the raw materials injected into the second mixing chamber 107. The raw materials are stirred, and the impeller 4052 and the small blade 4051 on the mixing head 405 can efficiently mix the raw materials in the second mixing chamber 107 during the high-speed rotation of the movable sleeve 403, and the 2 cm gap can provide a safe space for the impeller 4052 and the small blade 4051, so that the raw materials can flow in the gap and avoid the first mixing blade 404 from hindering the high-speed shearing of the impeller 4052 and the small blade 4051. During the mixing process, when the grinding component 5 is not working, the conical disk 501 can seal the second mixing chamber 107 to ensure the mixing effect;

[0065] During the mixing process, the inclined arc surface helps the fluid to move from the middle position of the conical disk 501 to the outside, avoiding the raw material from remaining on the conical disk 501. In addition, the small convex balls 5011 change the sputtering direction of the raw material when the impeller 4052 pushes the raw material to contact the conical disk 501, further improving the mixing effect.

[0066] During the processing, the height of the second driven bevel gear 506 can be adjusted by the hydraulic telescopic rod 3 to achieve the meshing and separation of the second driven bevel gear 506 and the active bevel gear 201. When the second driven bevel gear 506 is separated from the active bevel gear 201, the mixing component 4 operates normally and the grinding component 5 is in a stopped state, which is conducive to the full mixing of the raw materials. When the second driven bevel gear 506 is meshed with the active bevel gear 201, the mixing component 4 and the grinding component 5 operate simultaneously, which can quickly process the polyurethane insulating paint, and the different positions of the active bevel gear 201 teeth are respectively meshed with the first driven bevel gear 401 and the second driven bevel gear 506, and the speed ratio between the first driven bevel gear 401 and the second driven bevel gear 506 is adjusted, so that the mixing component 4 can quickly mix while slowly grinding;

[0067] During grinding, the connecting shaft 504 can drive the grinding base 503 and the grinding head 502 to rotate in the grinding groove 106 to grind the mixed raw materials. During the grinding process, the chamfering allows a certain space between the grinding head 502 and the top of the grinding groove 106, providing a certain feeding space for the grinding assembly 5, and the precision of the grinding head 502 is gradually increased. The three grinding heads 502 are used to grind step by step to ensure the grinding effect, and the ground raw materials can fall from the bottom of the grinding groove 106 into the first mixing chamber 105. At the same time, additives are added to the first mixing chamber 105 through the feeding pipe 104. The second mixing blade 505 can stir and mix the ground raw materials in the first mixing chamber 105 while the grinding head 502 rotates;

[0068] During the grinding process, the connecting shaft 504 is in a rotating state, and the convex ring 4033 in the circular ring 4032 can slide along the reciprocating thread groove 5041 on the top side wall of the connecting shaft 504, so that the movable sleeve 403 can slide reciprocatingly up and down in the fixed sleeve 402, and the mixing head 405 can move reciprocatingly up and down in the second mixing chamber 107, thereby improving the mixing effect and mixing efficiency. The hexagonal cylinder 4031 and the hexagonal groove 406 arranged in a hexagonal shape ensure that the movable sleeve 403 slides stably at the bottom end of the fixed sleeve 402, and the circular ring 4032 rotatably mounted on the top end of the hexagonal cylinder 4031 will idle at the top end of the hexagonal cylinder 4031 when the connecting shaft 504 does not rotate, thereby avoiding obstruction of the mixing component 4 during operation.

[0069] During the rotation of the connecting shaft 504, the conical disk 501 can rotate synchronously. During the rotation of the conical disk 501, the arc groove 5012 can be separated from the arc slide rail 1071 for a certain period of time. At this time, the mixed raw materials in the second mixing chamber 107 can be injected into the grinding groove 106, so as to realize intermittent feeding of the grinding assembly 5, relieve the pressure at the bottom of the grinding assembly 5, and realize efficient linkage between grinding and mixing.

[0070] After the mixed insulating paint is filtered through the filter screen 1011, it can be filled from the discharge pipe 101, and the second mixing blade 505 can push the particles intercepted on the filter screen 1011 to move during the rotation process, avoiding clogging of the filter screen 1011, thereby improving the production rate of the product, and at the same time ensuring the filtering effect and the quality of the product.

[0071] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
