Description

Technical Field

[0002] In the field of building materials, polycarboxylate water reducer is a high-performance concrete admixture. Its granulation process directly affects the dispersion and performance of the product. Traditional water reducer granulation devices mostly use static cooling or simple stirring methods, which makes it difficult to achieve uniform heating and efficient cooling of the material. It is easy to cause particle agglomeration or uneven temperature distribution, affecting the fluidity and stability of the final product. Existing equipment often relies on external air cooling or water cooling systems in the cooling process, which not only has high energy consumption, but also has limited cooling efficiency and cannot accurately control the material temperature. Especially when processing high-viscosity water reducers, local overheating or insufficient cooling problems are prone to occur. In addition, the discharge process of traditional granulation devices is often accompanied by material residue, which is inconvenient to clean, not only causing waste, but also may affect the purity of the next batch of products. Although some equipment is equipped with a scraping mechanism, most of them adopt an independent drive design, which has a complex structure and high maintenance cost, and it is difficult to meet the needs of continuous production. In response to these problems, the industry urgently needs a granulation device that can achieve dynamic cooling, automatic cleaning and stable operation to improve production efficiency and ensure product quality.

DETAILED DESCRIPTION

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1-Figure 5 The technical solution provided by the present invention specifically includes the following embodiments: Embodiment: A granulation processing device for polycarboxylate water-reducing agent and its components, including a base 1, a first support plate 2 fixedly connected to the four corners of the top of the base 1, a second support plate 3 fixedly connected to the inner side of the first support plate 2, a lightweight barrel 5 fixedly connected to the inner wall of the second support plate 3, an outer gear ring 7 fixedly connected to the surface of the lightweight barrel 5, a cooling component 6 is provided on the front side of the second support plate 3; the cooling component 6 includes a third support plate 601, the front side of the second support plate 3 is fixedly connected to the rear side of the third support plate 601, the inner wall of the third support plate 601 is rotatably connected to a first rotating rod 603, and the surface of the first rotating rod 603 is fixedly connected to a first gear 604; Driven by the rotating motor 602, the barrel rotation and the axial reciprocating motion of the condensing ring 610 are synchronized through the cylindrical cam 605-gear composite mechanism, forming a dynamic golden ratio cooling system, which can stably control the material temperature within the range of 45±2℃ and the cooling coverage rate exceeds 98%. The modularly designed cooling components are installed in a quick-release manner, equipped with a split copper tube condensing ring 610 and a precision gear transmission system. After 2000 hours of continuous operation, it still maintains excellent durability with a wear amount of less than 0.05mm. The self-cleaning system driven by the kinetic energy of the material during the discharge stage shows unique advantages: the falling material impacts the impeller 15 to drive the gear-rack mechanism, so that the cleaning ring 22 of the composite material completes the up and down scraping motion. When the material is not discharged, the impeller 15 stops rotating. The cleaning ring 22 is affected by its own gravity and falls naturally, completing the scraping below and its own reset. Its combined structure of a 3mm thick rubber layer with anti-slip grooves and a 2mm metal support layer can still maintain a stable scraping force of 15 to 20N at a high temperature of 150°C. Combined with the inclined diversion design, the barrel wall residue rate is reduced to less than 0.3%. The intelligent electric control valve 21 system achieves a quick response and quantitative discharge of 1 second through the linkage of pulse switch and speed sensor. At the same time, it uses inertial vibration to remove the material attached to the pipe wall, reducing the material residue by 12% compared with traditional valves. The mechanical transmission system has been precisely optimized. The return groove 606 of the cylindrical cam 605 adopts an alternating layout of annular groove sections and straight groove sections, combined with the oil-containing bearing sleeve 608 and linear guide rail to reduce operating noise. The cooling component 6 adopts a quick-release design. The third support plate 601 is fixed by hexagonal bolts. Only four M8 bolts need to be removed for replacement. The condensation ring 610 is a split copper tube structure with an embedded Φ6mm flow channel. It is connected to the external circulation system through a rotary joint. It is measured that when the inlet water temperature is 20°C, the material temperature in the barrel can be maintained at 45±2°C. The first gear 604 has a module of 2.5, and the side clearance with the outer gear ring 7 is controlled at 0.1mm to ensure smooth transmission. After 2000 hours of full-load operation, the gear wear of this module is less than 0.05mm.

[0017] The top of the first rotating rod 603 is fixedly connected to a cylindrical cam 605, and the surface of the cylindrical cam 605 is provided with a return groove 606 connected end to end. The surface of the outer gear ring 7 is meshed with the surface of the first gear 604. The top of the inner side of the first support plate 2 is fixedly connected to the fourth support plate 4, and the bottom of the fourth support plate 4 is fixedly connected to the first limit plate 609. The surface of the first limit plate 609 is slidably connected to the sliding sleeve 608. The front side of the sliding sleeve 608 is fixedly connected to the driven rod 607, and the rear side of the sliding sleeve 608 is fixedly connected to the condensation ring 610. The groove wall of the return groove 606 is slidably connected to the front end of the driven rod 607. When the rotating motor 602 is started, the cylindrical cam 605 and the first gear 604 are driven to rotate synchronously through the first rotating rod 603. Since the first gear 604 is engaged with the outer gear ring 7, the lightweight barrel 5 as a whole begins to rotate slowly. At the same time, the return groove 606 of the cylindrical cam 605 pushes the driven rod 607 to perform periodic reciprocating motion, so that the sliding sleeve 608 slides along the first limit plate 609, driving the condensation ring 610 to move up and down along the outer wall of the lightweight barrel 5. The lightweight barrel 5 made of aluminum alloy is evenly cooled during rotation, and the reciprocating motion of the condensation ring 610 covers the entire barrel wall to achieve dynamic cooling. This design realizes material tumbling and cooling at the same time through mechanical linkage, avoids local overheating, and improves granulation uniformity.

[0018] The bottom of the third support plate 601 is fixedly connected to a rotary motor 602 , and the output end of the rotary motor 602 is fixedly connected to the bottom of the first rotating rod 603 via a coupling.

[0019] The top of the lightweight barrel 5 is fixedly connected to a top cover plate 8, and a feed port is provided on the top of the top cover plate 8. The bottom of the lightweight barrel 5 is fixedly connected to a bottom sealing plate 13, and a discharge port is provided on the bottom of the bottom sealing plate 13. The bottom of the bottom sealing plate 13 is fixedly connected to an electric control valve 21, and the bottom of the electric control valve 21 is fixedly connected to a discharge pipe 19. When the valve body of the electric control valve 21 is in the open state, the discharge pipe 19 is connected to the interior of the lightweight barrel 5. The electric control valve 21 uses a 24V DC motor to drive the ball valve with a response time of less than 1 second. It is linked with the PLC to achieve quantitative discharge. The inner wall of the discharge pipe 19 is lined with PTFE coating, and the friction coefficient is as low as 0.04. When the sensor detects that the speed of the impeller 15 drops to the preset threshold, it automatically triggers the pulse switch 3 times, using inertial vibration to remove the material attached to the pipe wall.

[0020] A through hole 14 is provided through the top of the bottom sealing plate 13, and the bottom of the bottom sealing plate 13 is fixedly connected to the first L-shaped plate 10, and the inner wall of the first L-shaped plate 10 is slidably connected to the sliding rod 11, and the surface of the sliding rod 11 is slidably connected to the hole wall of the through hole 14, and the top of the first L-shaped plate 10 is fixedly connected to the connecting rod 9, and the top of the connecting rod 9 is fixedly connected to the bottom of the bottom sealing plate 13, and a mounting hole 20 is provided through one side of the first L-shaped plate 10, and the hole wall of the mounting hole 20 is rotatably connected to the second rotating rod 18, and the left end of the second rotating rod 18 is fixedly connected to the impeller 15, and the material of the lightweight barrel 5 is aluminum alloy; the bottom of the sliding rod 11 is fixedly connected to the second L-shaped plate 12, and the left end of the second L-shaped plate 12 is fixedly connected to the tooth plate 16, and the surface of the second rotating rod 18 is fixedly connected to the second gear 17, and the surface of the second gear 17 is meshed with the surface of the tooth plate 16; During discharge, the electrically controlled valve 21 is opened, and the falling material impacts the impeller 15, causing it to rotate. The second gear 17 is driven to rotate by the second rotating rod 18, and the toothed plate 16 meshing with the second gear 17 pushes the slide bar 11 to move up and down along the first L-shaped plate 10. The cleaning ring 22 fixed to the top of the slide bar 11 is activated accordingly. Its rubber outer layer scrapes off the residual material on the barrel wall, and the metal inner layer provides structural support. The inclined top design can guide the material to fall and prevent accumulation. This purely mechanical cleaning method does not require additional power and operates automatically using the kinetic energy of discharge. It is particularly suitable for polycarboxylate water reducers with higher viscosity and effectively reduces the risk of caking.

[0021] A cleaning ring 22 is fixedly connected to the top of the slide rod 11. The cleaning ring 22 is divided into two layers. The outer layer of the cleaning ring 22 is rubber, and the inner layer of the cleaning ring 22 is a metal ring. The outer layer of the cleaning ring 22 is fixedly connected to the inner layer of the cleaning ring 22. The surface of the top of the cleaning ring 22 is inclined, and the outer surface of the cleaning ring 22 is in sliding contact with the inner wall of the lightweight barrel 5. The cleaning ring 22 adopts an outer layer of 70° Shore hardness nitrile rubber + an inner layer of 304 stainless steel composite structure. The rubber layer is 3mm thick and has a 0.5mm deep anti-slip pattern molded in it. The metal ring has a wall thickness of 2mm and is fixed with epoxy resin glue. Tests show that the structure remains elastic at 150°C and the scraping force is stable in the range of 15 to 20N. When the cleaning ring moves up and down, its inclined surface design causes the material to be subjected to a downward component of force. Combined with the rotation of the lightweight barrel 5, the residual rate is less than 0.3%. The metal ring also acts as a counterweight to ensure that the tooth plate 16 and the second gear 17 always maintain an optimal meshing clearance of 0.2mm.

[0022] The cylindrical cam 605 is coaxially arranged with the first rotating rod 603. The return groove 606 is composed of annular groove segments extending along the circumference of the cylindrical cam 605 and straight groove segments extending along the axial direction of the cylindrical cam 605, which are alternately connected. The annular groove segments and the straight groove segments are smoothly connected by a circular arc transition segment. The sliding sleeve 608 cooperates with the return groove 606 through the driven rod 607 to form a cam pair. When the first rotating rod 603 drives the cylindrical cam 605 to rotate, the driven rod 607 performs periodic reciprocating motion along the return groove 606, driving the condensation ring 610 to perform axial reciprocating motion along the outer surface of the lightweight barrel 5. The cylindrical cam 605 adopts an alternating design of annular groove sections and straight groove sections. The straight groove sections correspond to the rapid lifting and lowering stroke of the condensation ring 610, the annular groove sections realize the reversing pause, and the arc transition section reduces the impact of the driven rod 607. The sleeve 608 adopts an oil-containing bearing and cooperates with the linear guide rail of the first limit plate 609. When the speed of the lightweight barrel 5 is 5rpm, the condensation ring 610 can complete 20 complete reciprocating cycles per minute. Its moving speed forms a golden ratio with the barrel body speed to ensure the cooling coverage rate.

[0023] In the present invention, the polycarboxylate water-reducing agent granulation processing device realizes the full process automation control of granulation, cooling, cleaning and discharging through a highly integrated mechanical linkage design. By organically integrating the rotary cooling system, linkage cleaning mechanism and intelligent discharging control into an efficient whole, the device adopts a lightweight aluminum alloy barrel body combined with an external gear ring transmission structure. Under the drive of the rotating motor 602, the cylindrical cam 605-gear composite mechanism synchronously realizes the rotation of the barrel body and the axial reciprocating motion of the condensation ring 610, forming a dynamic golden ratio cooling system, so that the material temperature is stably controlled within the range of 45±2℃, and the cooling coverage rate exceeds 98%. The modularly designed cooling component adopts quick-release installation, equipped with a split copper tube condensation ring 610 and a precision gear transmission system, and maintains excellent durability with a wear amount of less than 0.05mm after 2000 hours of continuous operation. The self-cleaning system driven by the kinetic energy of the material exhibits unique Advantages: Falling material impacts the impeller 15, driving the gear-rack mechanism, causing the composite cleaning ring 22 to complete an upward and downward scraping motion. When material is not discharged, the impeller 15 stops rotating, and the cleaning ring 22, under the influence of its own gravity, naturally falls, completing the scraping below and its own reset. Its combined structure of a 3mm thick rubber layer with anti-slip grooves and a 2mm metal support layer can still maintain a stable scraping force of 15-20N at a high temperature of 150°C. Combined with the inclined diversion design, the barrel wall residue rate is reduced to less than 0.3%. The intelligent electric control valve 21 system achieves a rapid response and quantitative discharge of 1 second through the linkage of pulse switching and speed sensing. At the same time, it uses inertial vibration to remove material attached to the pipe wall, reducing material residue by 12% compared to traditional valves. The mechanical transmission system has been precisely optimized. The return groove 606 of the cylindrical cam 605 adopts an alternating layout of annular groove segments and straight groove segments, combined with an oil-containing bearing sleeve 608 and a linear guide to reduce operating noise.

[0024] While the 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 can be made to the embodiments without departing from the principles and spirit of the invention.
