Description

Technical Field

[0001] This utility model relates to the field of concrete additive technology, and more specifically, to a water-reducing agent concentration device. Background Technology

[0002] Water-reducing agent concentration equipment is mainly used to concentrate the original water-reducing agent solution to improve its concentration and performance. This equipment typically consists of components such as a reaction vessel, concentrator, cooler, and filter, and achieves the concentration and purification of the water-reducing agent through a series of physical and chemical processes.

[0003] Existing water-reducing agent concentration equipment typically concentrates the liquid in the reactor through heating and depressurization. During the concentration process, water and other volatile components evaporate, thereby increasing the concentration of the water-reducing agent. However, existing equipment generally only performs single-stage concentration, resulting in weak concentration effects. Furthermore, the equipment requires readjustment for different concentration operations, making it less versatile.

[0004] The currently published Chinese utility model patent, entitled "A Polycarboxylate Water-Reducing Agent Concentration Device" with publication number CN218529803U, includes a concentration tank, support legs, concentration chambers, heaters, and a vacuum pump. In use, the water-reducing agent is added to the concentration chambers for concentration. The concentration chambers are equipped with multiple sets, and the heating temperature of the heaters inside them gradually increases. Different concentration chambers reduce the pressure to different degrees. Through the changes in pressure and heating temperature, the water-reducing agent can be concentrated to different degrees, which has the advantages of multiple concentrations and good concentration effect.

[0005] Although the device can concentrate multiple times, the separation of the aqueous solution and the water-reducing agent during concentration still uses the working principle of heating and pressurizing to generate water vapor for separation. In the actual implementation process, the water-reducing agent may undergo partial reaction due to temperature changes, causing a decline in the quality of the concentrated water-reducing agent solution. Utility Model Content

[0006] The purpose of this application is to provide a water-reducing agent concentration device that solves the technical problem of multiple concentrations in water-reducing agent concentration devices and improves concentration efficiency and concentration quality.

[0010] Preferably, the inner cylinder is fitted with an outer cylinder, and there is a gap between the outer cylinder and the side of the inner cylinder to form a water-permeable space, while the inside of the inner cylinder is a solvent reaction space.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] Example

[0032] Please refer to Figures 1-5 This utility model provides a water-reducing agent concentration device, including an inner cylinder 1, an outer cylinder 2, a permeable membrane layer 3, a stirring structure 4, a heating component 5, a condensing component 6, a filter channel 7, a water collection pipe 8, a liquid inlet 9, a pressure boosting valve 10, a pressure reducing valve 11, a liquid outlet 12, and a groove 13.

[0033] Furthermore, the top of the inner cylinder 1 is connected to a liquid inlet 9, through which the water-reducing agent mixture and the reaction agent required for concentration are introduced into the inner cylinder 1. The inner cylinder 1 is equipped with a stirring structure 4, and a heating component 5 is installed inside the stirring structure 4. The heating component 5 is located inside the inner cylinder 1.

[0034] Heating by heating component 5 and stirring by stirring structure 4 accelerate various reactions in the water-reducing mixed solution, thereby precipitating impurities and facilitating subsequent concentration processes.

[0035] Furthermore, the top of the inner cylinder 1 is connected to a pressure boosting valve 10 and a pressure reducing valve 11. The lower layer of the inner cylinder 1 is provided with multiple permeable membrane layers 3, which are arranged circumferentially on the cylinder wall of the inner cylinder 1. The permeable membrane layer 3 has a semi-permeable membrane structure that allows only water molecules to pass through, and the semi-permeable membrane structure connects the inner and outer environments of the inner cylinder 1.

[0036] Preferably, after the reaction of the water-reducing agent mixture is completed, the pressure is increased inside the inner cylinder 1 by the pressure boosting valve 10. Under the pressure, the water molecules mixed in the inner cylinder 1 will be squeezed and added through the semi-permeable membrane structure to separate the water-reducing agent and the aqueous solution, thereby increasing the concentration of the water-reducing agent and achieving the concentration effect of the water-reducing agent.

[0037] It is worth noting that each time the water-reducing agent mixture solution is introduced into the inner cylinder 1, it must submerge the permeable membrane layer 3 at the bottom of the inner cylinder 1 to prevent air in the inner cylinder 1 from passing through the permeable membrane layer 3 under pressure and losing the pressure-boosting effect.

[0038] Furthermore, an outer cylinder 2 is fitted over the inner cylinder 1, with a gap between the outer cylinder 2 and the side of the inner cylinder 1, which serves as a water-permeable space. The interior of the inner cylinder 1 is the solvent reaction space. Water molecules passing through the permeable membrane layer 3 are temporarily stored in the water-permeable space, separating from the water-reducing agent.

[0039] The solvent reaction space and water permeable space formed by the inner cylinder 1 and the outer cylinder 2 together constitute the solvent concentration chamber, realizing the complete water-reducing agent concentration work.

[0040] In this embodiment, at least two solvent concentration chambers are arranged vertically, and the two solvent concentration chambers are connected by a filter channel 7, which is equipped with a valve assembly.

[0041] The filter channel 7 includes a water pipe and a filter screen. The two ends of the water pipe are connected to the bottom surface of the upper inner cylinder 1 and the top surface of the lower inner cylinder 1, respectively. A filter screen is installed inside the water pipe.

[0042] Preferably, after the water-reducing agent mixture has been concentrated in a solvent concentration chamber, the valve assembly of the filter channel 7 can be opened. The filter screen will filter out the impurities generated after the reaction of the water-reducing agent mixture. Then, the concentrated water-reducing agent mixture will continue to be fed into the next solvent concentration chamber through the water pipe for further concentration, thereby improving the concentration quality (because when too many water molecules pass through the permeable membrane layer 3 of a single solvent concentration chamber, the water pressure from the water molecules will reduce the water permeability of the permeable membrane layer 3, so it is necessary to enter a new solvent concentration chamber for concentration).

[0043] It is worth noting that before the concentrated water-reducing agent mixture is introduced into the next solvent concentration chamber, the pressure-boosting valve 10 in the solvent concentration chamber that is currently undergoing pressure-boosting and concentration should be closed, and the pressure-reducing valve 11 should be activated to restore the pressure in the solvent concentration chamber to normal before it can be introduced into the next solvent concentration chamber.

[0044] Each solvent concentration chamber has an inlet 9 at the top, which is connected to the solvent reaction space. A valve assembly is installed at the inlet 9. The bottom solvent concentration chamber is connected to an outlet 12 at the bottom, which is also equipped with a valve assembly.

[0045] Preferably, when the device is concentrating the water-reducing agent mixture solution, the water-reducing agent mixture solution can be introduced into each solvent concentration chamber through the liquid inlet 9 to carry out the concentration work simultaneously, thereby improving the concentration efficiency of the water-reducing agent; when a higher concentration of water-reducing agent is required, the water-reducing agent mixture solution can be introduced only from the liquid inlet 9 of the top solvent concentration chamber, and then passed through multiple solvent concentration chambers in sequence for multiple concentrations to achieve high concentration of water-reducing agent.

[0046] Please refer to Figure 1 and Figure 2 In this embodiment, the inner wall of the inner cylinder 1 is a heat-conducting layer structure, and the outer wall of the inner cylinder 1 is a heat-insulating layer structure. When the heating component 5 in the inner cylinder 1 is heated, the inner cylinder 1 can be heated quickly through the heat-conducting layer structure, while the heat-insulating layer structure of the outer wall of the inner cylinder 1 can prevent excessively high temperatures from being conducted to the water-permeable space, making it difficult for water molecules that have passed through the permeable membrane layer 3 to cool and condense.

[0047] Preferably, the inner wall of the inner cylinder 1 is further provided with a plurality of grooves 13, which are arranged circumferentially inside the inner cylinder 1. The grooves 13 can increase the surface area of ​​the inner wall of the inner cylinder 1. Since the inner wall of the inner cylinder 1 is a heat-conducting layer structure, when the water-reducing agent mixture is stirred in the inner cylinder 1, the solution will have more contact with the heat-conducting surface of the inner wall of the inner cylinder 1, thereby improving the heating efficiency.

[0048] In this embodiment, a condensation component 6 is provided in the permeable space. The condensation component 6 is a refrigeration device, which is the prior art. The condensation component 6 includes a condenser tube and a refrigeration unit. The condenser tube surrounds the permeable space at least once, while the refrigeration unit cools the condensate and causes the condensate to flow in the condenser tube, thereby cooling the permeable space. This causes some water molecules that are active due to the heating of the inner cylinder 1 to quickly reduce their activity and condense into water droplets, which are easy to collect.

[0049] The outer cylinder 2, which forms the permeable space, is also equipped with a water collection pipe 8. The water collection pipe 8 includes a water pipe and a water storage tank. One end of the water pipe is connected to the bottom of the permeable space, and the other end of the water pipe is connected to the water storage tank. This allows the water that condenses in the permeable space to be collected and stored in the water storage tank through the water pipe, thus preventing excessive water accumulation in the permeable space and affecting the permeability function of the membrane layer 3.

[0050] Please refer to Figures 1-5 The stirring structure 4 includes a motor 401, a rotating shaft 402, and stirring blades 403.

[0051] Specifically, the motor 401 is fixedly and coaxially mounted on the top of the inner cylinder 1, the drive shaft of the motor 401 is fixedly connected to the rotating shaft 402, and the stirring blade 403 is fixedly mounted on the rotating shaft 402.

[0052] Preferably, the stirring blade 403 is configured as a spiral-shaped one-piece blade, and the one-piece blade is a heat-conducting structure.

[0053] The spiral blades increase the contact area between the blades and the water-reducing agent mixture, and the blades are a heat-conducting structure. When the heating component 5 is heated, the heat is conducted to the blades, thereby accelerating the rapid heating of the water-reducing agent mixture during the stirring process.

[0054] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description. The scope of this utility model is defined by the appended claims.
