[0002] Polycarboxylate superplasticizers, as indispensable key admixtures in modern concrete engineering, are prepared by precisely compounding various chemical raw materials. These compounding devices are widely used in building materials, fine chemicals, and other fields. Their core function is to efficiently and uniformly mix and react various liquid or solid initial raw materials according to specific process ratios, thereby producing a stable and high-quality polycarboxylate admixture product. The performance of this device directly affects the uniformity of the admixture product and the final engineering performance of the concrete, and is of great significance for improving the workability, strength, and durability of concrete.

[0003] However, some existing polycarboxylate additive compounding devices still have some shortcomings in practical applications that urgently need improvement. For example, the mixing systems of some devices are relatively simple in design, which can easily lead to insufficient mixing of raw materials, resulting in uneven concentrations or incomplete reactions, affecting the stability of product quality. At the same time, some devices have unsatisfactory purification effects or inconvenient filter media replacement when handling volatile harmful gases generated during the mixing process. Furthermore, material adhesion easily occurs on the inner walls of some compounding devices, which not only reduces production efficiency but also increases the difficulty and frequency of cleaning and maintenance.

[0004] To address this issue, a multi-component compounding device for polycarboxylate additives is proposed. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a polycarboxylate additive multi-component compounding device, comprising an outer tank, an inner tank fixedly connected inside the outer tank, a stirring mechanism inside the inner tank, a purification mechanism on the outside of the outer tank, multiple feed pipes fixedly connected to the top of the inner tank, a discharge pipe fixedly connected to the bottom of the outer tank, and a heating wire sleeved on the outside of the inner tank;

[0007] The stirring mechanism includes a motor, which is fixedly connected to the top of the inner tank. A square rod is fixedly connected to the output end of the motor. A sleeve is slidably connected to the outside of the square rod. Multiple stirring rods are fixedly connected to the outside of the sleeve.

[0009] The purification mechanism includes a purification box, which is fixedly connected to the outside of the outer tank. A connecting pipe is fixedly connected to the outside of the purification box, and the end of the connecting pipe away from the purification box is fixedly connected to the top of the inner tank. An activated carbon plate is slidably connected inside the purification box, and a fixing block is fixedly connected to one side of the activated carbon plate. A fixing component is fixedly connected to the outside of the purification box, and an air outlet pipe is fixedly connected to the top of the purification box.

[0010] As a further description of the above technical solution:

[0011] The fixing component includes an outer shell, which is fixedly connected to the outside of the purification box. An inner shell is fixedly connected inside the outer shell. A U-shaped groove is opened on the outside of the inner shell. A pin is slidably connected inside the inner shell. A spring is sleeved on the outside of the pin. A pad is fixedly connected to the outside of the pin. A locking block is fixedly connected to the outside of the pad.

[0012] As a further description of the above technical solution:

[0013] One end of the discharge pipe extends through the bottom of the inner tank, and a valve is installed inside the discharge pipe.

[0014] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model employs a mixing mechanism where a swashplate and upper and lower rollers work together to drive the mixing rod in a combined rotational and reciprocating motion. Simultaneously, a scraper closely adheres to the inner tank wall for cleaning. This achieves the technical effect of deep and uniform mixing of multiple raw materials and real-time removal of adhering substances from the tank wall. Compared to existing mixing devices that only provide single-plane rotational stirring or lack effective anti-sticking measures, this design solves the shortcomings of insufficient mixing leading to stratification, material adhesion to the tank wall affecting mixing efficiency, and subsequent cleaning.

[0024] 2. In this utility model, by setting an activated carbon plate to adsorb gas in the purification mechanism and designing a locking mechanism for the pin, the function of temporarily fixing the pin after it is pulled out is achieved by using the cooperation of the locking block and the U-shaped groove. This achieves the technical effect of effectively purifying the gas generated during the production process and making the replacement of the activated carbon plate quick and labor-saving. Compared with some existing filter material replacement devices, which have complex locking structures or lack temporary positioning support during replacement, resulting in time-consuming and labor-intensive operations, this solution overcomes the defects of inconvenient maintenance and low replacement efficiency.

[0035] The outer tank 7 serves as the overall support and containment structure of the device, while the inner tank 3, fixedly connected inside, is the core container for the raw material mixing reaction.

A purification mechanism is located outside the outer tank 7 to handle gases generated during the mixing process. Multiple feed pipes 8 are fixed to the top of the inner tank 3 for feeding various raw materials into it. A discharge pipe 4 is fixed to the bottom of the outer tank 7 and extends through the bottom of the inner tank 3 to discharge the finished product after mixing; a valve 5 installed inside the pipe controls the discharge of materials.

The side of the scraper away from the stirring rod 6 abuts against the inner wall of the inner tank 3 to scrape off the material adhering to the tank wall and prevent sticking. The swash plate 26 fixedly connected to the outside of the sleeve 27 cooperates with the upper roller 23 and lower roller 25 on the connecting rod 24 fixedly connected to the top wall of the inner tank 3 to slide, realizing the axial reciprocating motion of the sleeve 27 during rotation, thereby driving the stirring rod 6 to stir up and down. The connecting rod 24 is fixedly connected to the upper roller 23 and lower roller 25 from top to bottom, which provide guidance and support for the swash plate 26.

[0036] Reference Figures 1-4 The purification mechanism includes a purification box 11, which is fixedly connected to the outside of the outer tank 7. A connecting pipe 10 is fixedly connected to the outside of the purification box 11. The end of the connecting pipe 10 away from the purification box 11 is fixedly connected to the top of the inner tank 3.

[0037] The purification chamber 11 is fixedly connected to the outside of the outer tank 7 and is the main cavity for containing and purifying the gas. The connecting pipe 10 is fixedly connected to the outside of the purification chamber 11 and extends to the top of the inner tank 3; its function is to guide the gas generated in the inner tank 3 into the purification chamber 11 for treatment. The activated carbon plate 12, which is slidably connected inside the purification chamber 11, is the core adsorption and filtration material used to adsorb impurities and harmful components in the gas. The fixing block 16 fixedly connected to one side of the activated carbon plate 12 is a structure used to install and fix the activated carbon plate 12 inside the purification chamber 11 in conjunction with the fixing assembly. The fixing assembly fixedly connected to the outside of the purification chamber 11 is used to achieve quick loading and unloading and reliable locking of the activated carbon plate 12. The exhaust pipe 1 fixedly connected to the top of the purification chamber 11 is used to discharge the clean gas purified by the activated carbon plate 12 into the external environment.

[0038] Reference Figures 1-4 The fixing assembly includes an outer shell 17, which is fixedly connected to the outside of the purification box 11. An inner shell 19 is fixedly connected inside the outer shell 17. A U-shaped groove 18 is provided on the outside of the inner shell 19. A pin 20 is slidably connected inside the inner shell 19. A spring 13 is sleeved on the outside of the pin 20. A pad 14 is fixedly connected to the outside of the pin 20. A locking block 15 is fixedly connected to the outside of the pad 14. One end of the spring 13 is fixedly connected to the top of the pad 14, and the other end of the pad 14 abuts against the inner wall of the inner shell 19.

A pull ring is fixedly connected to the top of the pin 20.

[0039] The outer shell 17 is fixedly connected to the outside of the purification box 11, providing an installation base and external protection for the fixed components. The inner shell 19, fixedly connected inside the outer shell 17, is the main receiving and guiding structure for the pin 20. A U-shaped groove 18 on the outer side of the inner shell 19 cooperates with a locking block 15, allowing the pin 20 to be temporarily locked by rotating the pin 20 after it has been pulled out of the fixing block 16, causing the locking block 15 to engage in the U-shaped groove 18. The pin 20, slidably connected inside the inner shell 19, is a key component for locking the activated carbon plate 12; one end of it is inserted into the fixing block 16 of the activated carbon plate 12. A spring 13 sleeved on the outer side of the pin 20 provides a restoring force, allowing the pin 20 to automatically insert into the fixing block 16 when no external force is applied. The pad 14, fixedly connected to the outer side of the pin 20, serves as the bearing surface and limiting structure for the spring 13, allowing the pin 20 to slide smoothly within the inner shell 19. One end of the spring 13 is fixedly connected to the top of the pad 14, and the other end of the pad 14 abuts against the inner wall of the inner shell 19, ensuring the correct force application of the spring 13. The locking block 15, fixedly connected to the outer side of the pad 14, cooperates with the U-shaped groove 18 to temporarily lock the pin 20. The pull ring fixedly connected to the top of the pin 20 facilitates manual operation, used to pull the pin 20 out of the fixing block 16, thereby unlocking the activated carbon plate 12. The pad 14 is slidably connected inside the inner shell 19, ensuring the smooth movement of the pin 20.

[0040] Working principle: When the device is running, various raw materials are first precisely fed into the inner tank 3 through the feed pipe 8. Then, the motor 9 is started, driving the square rod 22 to rotate inside the inner tank 3. Since the square hole in the middle of the sleeve 27 matches the square rod 22, the sleeve 27 rotates synchronously, driving the stirring rod 6 fixed on it to perform efficient circumferential stirring of the raw materials in the inner tank 3.

[0041] As the sleeve 27 rotates, its outer scraper 2 moves synchronously against the inner wall of the inner tank 3, continuously scraping and cleaning the material adhering to the tank wall, effectively preventing raw material adhesion and ensuring uniform mixing. Because the swashplate 26 slides between the fixed upper roller 23 and lower roller 25, the sleeve 27, while rotating with the square rod 22, also experiences axial up-and-down reciprocating motion on the square rod 22. This combined motion allows the stirring rod 6 to fully mix the raw materials in three-dimensional space, greatly improving the mixing effect.

[0042] Throughout the mixing process, the heating wire 21 surrounding the inner tank 3 simultaneously heats the material inside the tank, thereby promoting rapid fusion and reaction between the raw material components by increasing the temperature.

[0043] Once the raw materials are mixed evenly and reach the predetermined state, the volatile gases generated during the cooling process will be guided into the purification chamber 11 through the connecting pipe 10. In the purification chamber 11, the gas passes through the activated carbon plate 12, where harmful components are effectively adsorbed and purified. The clean gas is finally discharged into the air through the exhaust pipe 1, and the cooled material is finally discharged through the discharge pipe 4.

[0044] When the activated carbon plate 12 becomes saturated and needs to be replaced, the operator first pulls the pull ring to disengage the pin 20 from the fixing block 16. Then, the pin 20 is rotated to engage the locking block 15 in the U-shaped groove 18, temporarily locking the pin 20 without requiring continuous force. At this point, the old activated carbon plate 12 can be easily removed and a new one installed. After replacement, the pin 20 is slightly pulled back and rotated in the opposite direction to disengage the locking block 15 from the U-shaped groove 18. After releasing the pull ring, the pin 20 automatically re-inserts into the fixing block 16 under the reset action of the spring 13, securely locking the new activated carbon plate 12.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
