Description

Technical Field

[0001] This utility model relates to the field of water-reducing agent production technology, specifically to a water-reducing agent production device. Background Technology

[0002] Water-reducing agent is an important concrete admixture and one of the key products of the new building materials industry. In the production process of water-reducing agent, its raw materials need to be mixed and processed, which leads to the provision of a water-reducing agent production device.

[0003] For example, the device with announcement number "CN220940769U" incorporates a cleaning mechanism. When cleaning the inside of the mixing tank is required, cleaning water can be sent into the sealed sleeve via an external water pipe, then sequentially into the driven spiral agitator, and sprayed out through nozzles to rinse the inner wall of the mixing tank and the active spiral agitator, ensuring good cleaning effect and ease of use. However, in the above-mentioned device, the overall structure is relatively enclosed, and the agitator has significant obstruction inside the main body, making subsequent cleaning inconvenient and reducing its practicality. Furthermore, when mixing water-reducing agent raw materials, some monomers (such as acrylic acid) or sulfonated raw materials are low-viscosity liquids, but their viscosity may gradually increase after mixing with other additives (such as slow-release agents and stabilizers). Discharging solely through the outlet is slow and results in low production efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems of the relatively enclosed nature of the device and the large obstruction of the stirring rod inside the parent body, which makes it inconvenient to clean later and has low practicality. At the same time, when mixing water-reducing agent raw materials, some monomers (such as acrylic acid) or sulfonated raw materials are low-viscosity liquids, but their viscosity may gradually increase after being mixed with other additives (such as slow-release agents and stabilizers). Discharging through the outlet alone is slow and has low production efficiency. Therefore, this invention proposes a water-reducing agent production device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A water-reducing agent production device is designed, comprising a frame, a first outer shell, and a tank. The outer walls of the frame are fixedly connected to the first outer shell on both sides. The first outer shell has a discharge structure inside. The upper end of the outer wall of the tank is threadedly connected to a top cover. The tank has a mixing and receiving structure inside. The lower end of the outer wall of the tank is fixedly connected to a second outer shell.

[0007] Preferably, the hybrid retraction structure includes a second motor, a first gear fixedly connected to the end of the output shaft of the second motor, the outer wall of the first gear meshing with the second gear, a housing fixedly connected to the inner wall of the second gear, a slide rod fixedly connected to the upper end of the inner wall of the housing, the outer wall of the slide rod slidingly connected to a rack, the outer wall of the rack meshing with multiple third gears, the rotating shaft of the third gear rotatably connected to the housing through a sealed bearing, and an electric telescopic rod fixedly connected to the lower end of the inner wall of the second housing, the output end of the electric telescopic rod rotatably connected to the rack through a bearing.

[0008] Preferably, the outer wall of the second motor is fixedly connected to the second housing via a bracket, and the first gear rotating shaft is rotatably connected to the second housing and the tank via a bearing.

[0009] Preferably, the lower end of the outer wall of the shell is rotatably connected to the tank body via a sealed bearing, and the ends of the multiple third gear rotating shafts are fixedly connected with stirring rods.

[0010] Preferably, the discharge structure includes a first motor, a worm gear is fixedly connected to the end of the output shaft of the first motor, the two ends of the worm gear are rotatably connected to the first housing through bearings, the outer wall of the worm gear is meshed with a worm wheel, the rotating shaft of the worm wheel is rotatably connected to the first housing and the frame through bearings, the end of the rotating shaft of the worm wheel is fixedly connected to the tank body, and cylinders are fixedly connected to the lower ends of both sides of the tank body.

[0011] Preferably, the outer wall of the first motor is fixedly connected to the frame via a bracket, and the cylinder is slidably connected to the groove machined on the inner wall of the frame.

[0012] The water-reducing agent production device proposed in this utility model has the following advantages: Through the mixing and discharging structure, the second motor starts and drives the first gear to rotate through the bearings in the second outer shell and the tank. Then, the first gear drives the second gear to rotate. The rotation of the second gear drives the shell to rotate through the sealed bearings in the tank. The moving telescopic rod starts and drives the rack to slide downward on the outer wall of the slide rod. The rack is restricted by the slide rod and can only move up and down. Then, the rack drives multiple third gears to rotate relative to each other in the shell through the sealed bearings. The third gears drive multiple stirring rods to move upward to a vertical state. Finally, the electric telescopic rod drives multiple third gears to rotate. The third gears drive the stirring rods to move to a vertical state, reducing the obstruction of the stirring rods to the inside of the tank, making it easier to clean later and effectively improving practicality.

[0013] Through the discharge structure, the two first motors start simultaneously, driving the worm gear to rotate through the bearings in the first housing. The rotation of the worm gear drives the worm wheel to rotate through the bearings in the first housing and frame. In turn, the worm wheel drives the tank to tilt forward. Finally, the two motors drive the tank forward to clean it, pouring the mixed water-reducing agent raw material support inside the tank into it, effectively speeding up the discharge speed and thus improving production efficiency.

[0026] The outer wall of the slide rod 7 is slidably connected to the rack 205. The rack 205 is restricted by the slide rod 7 to move only up and down. The outer wall of the rack 205 is meshed with multiple third gears 207. The rotating shaft of the third gear 207 is rotatably connected to the housing 204 through a sealed bearing.

The lower ends of both sides of the tank body 4 are fixedly connected with cylinders 104.

[0030] Working principle:

[0031] Water-reducing agent production mixing process:

[0032] When it is necessary to mix the water-reducing agent raw materials (such as acrylic acid, methacrylic acid, and polyethylene glycol, which need to be dissolved by heating), first rotate the top cover 6 outward to separate it from the tank body 4, pour the water-reducing agent raw materials into the tank body 4 and rotate the top cover 6 back. The upper end of the inner wall of the top cover 6 is fixed with an elastic sealing ring to ensure relative sealing with the tank body 4. Then connect the external power supply of the second motor 8. The second motor 8 starts and drives the first gear 202 to rotate through the bearings in the second outer shell 8 and the tank body 4.

[0033] Then, the first gear 202 drives the second gear 203 to rotate. The rotation of the second gear 203 drives the shell 204 to rotate inside the tank 4 through the sealed bearing. The rotation of the shell 204 drives the rack 205 and multiple third gears 207 to revolve. The rack 205 can rotate through the bearing at the output end of the electric telescopic rod 206. Then, the third gear 207 drives the stirring rod to revolve to stir the water-reducing agent raw materials. An observation window is provided on the front side of the tank 4 to observe the mixing of the water-reducing agent.

[0034] Water-reducing agent discharge process:

[0035] After the water-reducing agent raw materials are mixed, place the outer shell hopper on the front side of the tank 4, the second motor 201 stops moving and the top cover 6 is opened, and then connect the power lines of the two first motors 101 to a PLC controller. Through programming and other operations, the two first motors 101 can be started simultaneously. The simultaneous start of the two first motors 101 drives the worm gear 102 to rotate in the first outer shell 5 through the bearing. The rotation of the worm gear 102 drives the worm wheel 103 to rotate in the first outer shell 5 and the frame 3 through the bearing.

[0036] Then, the worm gear 103 drives the tank 4 to tilt forward, while the tank 4 drives the cylinder 104 to slide backward in the groove processed on the inner wall of the frame 3. The tank 4 can only tilt forward and backward due to the restriction of the cylinder 104. In addition, the worm gear 103 and the worm 102 mesh with a self-locking function. When the worm 103 stops rotating, the tank 4 can be positioned. The tank 4 tilts forward to the material box to discharge the mixed water-reducing agent. This movement can be used to discharge the mixed water-reducing agent.

[0037] Tank cleaning work:

[0038] When the inside of the tank needs to be cleaned, the first motor 101 is reversed to reset the tank 4 to a vertical position. Then, the external power supply of the electric telescopic rod 206 is connected. The electric telescopic rod 206 starts and drives the rack 205 to slide downward on the outer wall of the slide rod 7. The rack 206 can only move up and down due to the restriction of the slide rod 7. In turn, the rack 206 drives multiple third gears 207 to rotate relative to each other in the shell 204 through sealed bearings. The third gears 207 drive multiple stirring rods to move upward to a vertical position, which can reduce the obstruction of the stirring rods to the inside of the tank 4.

[0039] Then, the staff can use a high-pressure water gun to rinse the inside of the tank 4, the stirring rod, and the shell 204. The rinsing wastewater is the same as the above-mentioned water-reducing agent discharge method. Controlling the electric telescopic rod 206 to push the rack 205 upward to reset can reset multiple stirring rods laterally. Then, in the same way as the above-mentioned working method, the subsequent water-reducing agent raw materials can be mixed and produced.
