Abstract
Description
Technical Field
[0001] This utility model relates to the field of water-reducing agent production technology, and in particular to a stirring mechanism for water-reducing agent production. Background Technology
[0002] Water-reducing agents are a core category of concrete admixtures. They reduce the amount of mixing water without compromising the workability of concrete. Their core function is to adsorb surfactants onto the surface of cement particles, imparting a negative charge to the particles. This charge repulsion breaks up particle agglomeration, releasing trapped water and improving concrete fluidity. Based on chemical composition, they can be classified into lignin sulfonate, naphthalene-based, aliphatic, and polycarboxylate-based agents. Among these, polycarboxylate-based water-reducing agents are currently the mainstream product due to their high water reduction rate, good slump retention, and environmental friendliness. They are widely used in commercial concrete, precast components, and high-rise buildings, improving concrete strength and durability while reducing cement usage, thus offering both technical and economic value. Currently, the production of water-reducing agents requires mixing multiple raw materials. Solid raw materials are often added all at once, leading to low mixing efficiency, thus requiring improvement. Utility Model Content

[0024] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a stirring mechanism for the production of a water-reducing agent.
[0025] A mixing mechanism for water-reducing agent production includes a support base 1 and a mixing drum 2, the mixing drum 2 being disposed on the support base 1. It further includes: a mixing mechanism disposed on the mixing drum 2 for mixing operations; and a feeding mechanism disposed on the mixing drum 2 for controlling the feeding speed. The feeding mechanism includes: a feeding cylinder 3 disposed on the mixing drum 2 and fixedly connected to it; a feeding box 4 disposed on the mixing drum 2 and fixedly connected to it; a push rod 5 disposed on the feeding box 4 and rotatably connected to it; a feeding pipe 6 disposed on the feeding box 4 and fixedly connected to it; two feeding wheels 7 disposed within the feeding pipe 6 for controlling the feeding speed; two gears 8 disposed on the feeding wheels 7 and fixedly connected to them; a mounting shell 10 disposed on the feeding box 4 and fixedly connected to it; and a first motor 9 disposed within the mounting shell 10 and fixedly connected to it.
[0026] refer to Figure 1 and Figure 2 In a preferred embodiment, the feeding mechanism further includes: a drive unit disposed on the feeding box 4 for providing power to drive the push rod 5 to rotate; and a feeding unit disposed inside the feeding box 4 for moving the raw materials.
[0027] When operating with this setup, solid raw materials are added to the feed box 4 through the feed inlet 13, liquid raw materials are added to the feed cylinder 3, and solid raw materials enter the feed pipe 6. The first motor 9 drives one of the gears 8, which in turn drives the other gear 8 to rotate. The two feed wheels 7 rotate synchronously through the transmission of the two gears 8. The opening angle between the two feed wheels 7 is controlled by the rotation of the gears 8 to precisely control the speed of the raw materials passing through the feed pipe 6, so that the solid raw materials can continuously and evenly enter the mixing drum 2, while the liquid raw materials directly enter the mixing drum 2 precisely through the control valve in the feed cylinder 3. The push rod 5 has threaded rods at both ends with opposite thread directions, and the push rod 5 is fixedly connected to the output end of the second motor 12. At the same time, the feed pipe is fixedly connected to the mixing drum 2.
[0028] refer to Figure 4 and Figure 5 In a preferred embodiment, the drive unit includes: a fixed housing 11, which is disposed on the feed box 4 and fixedly connected to the feed box 4; and a second motor 12, which is disposed inside the fixed housing 11 and fixedly connected to the fixed housing 11.
[0029] refer to Figure 2 and Figure 4 In a preferred embodiment, the feeding unit includes: a feeding port 13, which is disposed on the feeding box 4 for feeding; and a conveyor belt 14, which is disposed inside the feeding box 4 for moving raw materials.
[0030] When the operation is set up in this way, the solid raw material is conveyed to the position of the push rod 5 by the conveyor belt 14 under the drive of the second motor 12. Under the action of the drive unit, the push rod 5 is driven to rotate by the second motor 12, so that the solid raw material moves towards the center until the raw material is pushed into the feed pipe 6.
[0031] refer to Figure 3 In a preferred embodiment, the stirring mechanism includes: a mounting part disposed on the stirring drum 2 for component mounting; and a stirring part disposed on the mounting part for stirring operation.
[0032] refer to Figure 3 In a preferred embodiment, the mounting unit includes: a mounting frame 15, which is disposed on the mixing drum 2 and fixedly connected to the mixing drum 2; and a third motor 19, which is disposed inside the mounting frame 15 and fixedly connected to the mounting frame 15.
[0033] refer to Figure 3 In a preferred embodiment, the stirring unit includes: a stirring shaft 16, which is disposed on the output end of the third motor 19 and fixedly connected to the output end of the third motor 19; a first stirring blade 17, which is disposed on the stirring shaft 16 and fixedly connected to the stirring shaft 16; and a second stirring blade 18, which is disposed on the stirring shaft 16 and fixedly connected to the stirring shaft 16.
[0034] When the equipment is set up in this way, the raw materials entering the mixing drum 2 are driven by the third motor 19, and the mixing shaft 16 drives the first mixing blade 17 and the second mixing blade 18 to rotate at high speed, so as to fully mix the raw materials and ensure that the various raw materials are mixed evenly. The second mixing blade 18 can also prevent the formation of a mixing dead zone at the bottom of the mixing drum 2.
[0035] This device, through its feeding mechanism, enables continuous and uniform feeding of solid raw materials, avoiding the low mixing efficiency caused by traditional one-time additions. Furthermore, the feeding wheel 7 and gear 8 transmission design within the feeding mechanism allow for precise control of the feeding speed, further improving the mixing effect and product quality. The mixing mechanism, with its combination of first and second mixing blades 17 and 18, increases the mixing area, allowing for more thorough mixing of the raw materials within the mixing drum 2. This improves the production efficiency and quality of the water-reducing agent, and the second mixing blade 18 also prevents dead zones from forming at the bottom of the mixing drum 2.
[0036] Working Principle: During operation, solid raw materials are added to the feed box 4 through the feed inlet 13, while liquid raw materials are added to the feed cylinder 3. The solid raw materials are conveyed to the push rod 5 position by the conveyor belt 14 under the drive of the second motor 12. Under the action of the drive unit, the push rod 5 is rotated by the second motor 12, causing the solid raw materials to move towards the center until they are pushed into the feed pipe 6. At this time, the first motor 9 drives one of the gears 8, which in turn drives the other gear 8 to rotate. The two feed wheels 7 rotate synchronously through the transmission of the two gears 8. The rotation of wheel 8 controls the included angle between the openings of the two feed wheels 7 to precisely control the speed at which the raw materials pass through the feed pipe 6, so that solid raw materials can continuously and evenly enter the mixing drum 2, while liquid raw materials directly enter the mixing drum 2 precisely through the control valve in the feed cylinder 3; the raw materials entering the mixing drum 2 are driven by the third motor 19, and the stirring shaft 16 drives the first stirring blade 17 and the second stirring blade 18 to rotate at high speed, so as to fully stir the raw materials and ensure that the various raw materials are mixed evenly. This effectively solves the problem that traditional stirring devices cannot continuously add solid raw materials, and improves the stirring efficiency and the production quality of water-reducing agents.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
