Description

Technical Field

[0001] This invention relates to the field of anti-clogging technology for polycarboxylate superplasticizers, specifically to a pulverization process and pulverization equipment for polycarboxylate superplasticizers. Background Technology

[0002] Polycarboxylate superplasticizer (PCE) is a high-performance concrete admixture primarily used to improve concrete fluidity and reduce water consumption. Through its unique molecular structure design, it achieves highly efficient dispersion of cement particles, thereby significantly improving the workability and strength of concrete.

[0003] In the pulverization process of polycarboxylate superplasticizers, the raw materials are typically heated and compressed using thermal energy to form powdered granules. This process may involve burning fuel or using electricity to provide the necessary heat. During the subsequent operation of the pulverizing machine, the raw materials may contain volatile substances such as moisture and volatile organic compounds. In the high-temperature environment of the pulverizing machine, these substances may volatilize. The high temperature inside the pulverizing machine, combined with the squeezing and friction of the pressure rollers, causes the release of volatile substances from the raw materials. These substances evaporate at high temperatures, potentially forming polluting gases inside the pulverizing machine. This volatilization process not only affects the quality of the granules but may also cause environmental pollution. Therefore, appropriate measures need to be taken during the pulverization process to control the release of volatile substances and reduce the generation of polluting gases. Furthermore, during the granulation process of polycarboxylate superplasticizer, the raw material is continuously fed into the pulverizer through the feed port outside the processing cylinder. If the moisture content of the biomass raw material is uneven, it can cause stickiness inside the pulverizer, leading to particle adhesion and blockage. Both excessively high and low moisture content can cause this problem. If the polycarboxylate superplasticizer has inconsistent sizes, it may create a flow of particles of different sizes within the pulverizer, causing particle accumulation. This uneven particle flow leads to uneven pressure distribution within the pulverizer, further increasing the risk of blockage. Therefore, in view of this, the present invention proposes a pulverization process and pulverization equipment for polycarboxylate superplasticizer to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a pulverization process and pulverization equipment for polycarboxylate superplasticizers, thereby resolving the technical issues raised in the background section.

S1, Raw material preparation, the main raw materials include polycarboxylate ether monomers, stabilizers and additives; S2, reaction synthesis, involves mixing polycarboxylic acid ether monomers and auxiliary materials in a certain proportion and carrying out a polycondensation reaction at a set temperature to generate polycarboxylic acid ether polymers; S3, Drying treatment: The polycarboxylic acid ether polymer synthesized by the reaction is dried to remove residual solvent and moisture. The dried product needs to be pulverized to obtain a uniform powder. S4, Crushing and Sieving: The dried polycarboxylate ether polymer is crushed by crushing equipment to obtain uniform powder. The crushed powder is then sieved to ensure consistent particle size. S5. Packaging and Storage: The crushed and sieved polycarboxylate superplasticizer powder is packaged and stored in a dry, ventilated environment to prevent moisture absorption and clumping.

[0006] A pulverizing device for polycarboxylate superplasticizer includes a machine base, a motor mounted on top of the machine base, a processing cylinder mounted on one end of the motor, a material inlet on the outer wall of the processing cylinder, a rotating shaft rotatably connected inside the processing cylinder, a waste gas treatment mechanism above the processing cylinder, and a filtration and anti-clogging mechanism inside the processing cylinder. The waste gas treatment mechanism is used to purify the waste gas generated during the treatment process of the treatment cylinder; The filter anti-clogging mechanism is used for automatic shaking to prevent the raw materials inside the processing cylinder from becoming clogged.

[0007] Preferably, the exhaust gas treatment mechanism includes an adjusting shell fixedly connected to the top of the treatment cylinder, a pressure valve communicating with the top of the adjusting shell, a fixing plate fixedly connected to the inner wall of the adjusting shell, a storage cylinder slidably connected to the top of the fixing plate, an inclined plate fixedly connected to the lower surface of the storage cylinder, a prompting ring slidably connected to the inner wall of the adjusting shell, a roller rotatably connected to one end of the prompting ring near the inclined plate, and a spring sleeved on the outer wall of the prompting ring.

[0008] Preferably, the outer wall of the storage cylinder is uniformly provided with through grooves, and zeolite strips are placed inside the storage cylinder.

[0009] Preferably, the adjusting shell is a telescopic structure, the indicator ring is installed at the non-telescopic position of the adjusting shell, and the adjusting shell has a groove at the position corresponding to the indicator ring.

[0010] Preferably, the roller is located on the movement path of the inclined panel, and the two ends of the spring are fixedly connected to the prompting ring and the roller, respectively.

[0011] Preferably, the filter anti-clogging mechanism includes a fixed shaft fixedly connected above the rotating shaft, a slide rail installed above the fixed shaft, and curved rods fixedly connected to both ends of the slide rail. Positioning plates are slidably connected to the outer walls of the curved rods. Limiting rings are fixedly connected to the lower surface of the positioning plates. The limiting rings are fixedly connected to the inner wall of the processing cylinder. A filter plate is fixedly connected above the curved rods.

[0012] Preferably, a cylindrical protrusion is fixedly connected at an eccentric position above the fixed shaft, and the slide rail and the fixed shaft are slidably connected through the cylindrical protrusion.

[0013] Preferably, the crank is L-shaped, and the surface of the filter plate is uniformly provided with arc grooves.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) Since a pressure valve is installed on the top of the regulating shell, when the gas inside the regulating shell exceeds the pressure value of the pressure valve, the pressure valve will be automatically triggered to change from the closed state to the open state, so that the purified gas inside the regulating shell can be discharged normally. The waste gas generated inside the automatic adsorption and purification polycarboxylate superplasticizer pulverizer can effectively remove particulate matter, harmful gases and pollutants in the waste gas. The waste gas emission after purification treatment can reduce the concentration of pollutants in the atmosphere and reduce the negative impact on the environment. In addition, the waste gas emission after purification treatment can improve the living and working environment of operators and nearby residents. (2) By observing the status of the indicator ring, the insufficient adsorption capacity of zeolite can be detected in time. Measures can be taken before the problem worsens to avoid greater losses due to equipment performance degradation. This helps to reduce operation and maintenance costs and repair expenses. In addition, timely detection of insufficient adsorption capacity can prompt staff to maintain, regenerate or replace zeolite to maintain the efficient operation of the equipment. This helps to maintain the stability and efficiency of the waste gas treatment system. (3) It can prevent the pulverizer of biomass polycarboxylate superplasticizer from being blocked when encountering impurities in the raw materials or the adhesion between particles during operation. This can increase the permeability between particles, prevent the raw materials from getting stuck or blocked during processing, and prevent internal blockage. It can also ensure the continuous and efficient operation of the pulverizer of biomass polycarboxylate superplasticizer, avoid reducing production efficiency due to internal blockage, and increase the frequency of maintenance and cleaning. In addition, it can also prevent the extra load caused by blockage during equipment operation, which can easily cause wear and damage to the equipment. By moving the filter plate, the load on the equipment can be reduced and the service life of the equipment can be extended. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] First Embodiment Please refer to Figure 1 and Figure 2 As shown, a pulverization process and pulverization equipment for polycarboxylate superplasticizer includes a machine base 1, a motor 11 installed above the machine base 1, a processing cylinder 12 installed at one end of the motor 11, a material conveying port opened on the outer wall of the processing cylinder 12, a rotating shaft 13 rotatably connected inside the processing cylinder 12, a waste gas treatment mechanism 2 installed above the processing cylinder 12, and a filter anti-clogging mechanism 3 installed inside the processing cylinder 12. Please refer to Figures 3 to 5As shown, the exhaust gas treatment mechanism 2 includes an adjusting shell 21 fixedly connected to the upper part of the treatment cylinder 12. A pressure valve 28 is connected to the upper part of the adjusting shell 21. A fixing plate 22 is fixedly connected to the inner wall of the adjusting shell 21. A storage cylinder 23 is slidably connected to the upper part of the fixing plate 22. An inclined plate 24 is fixedly connected to the lower surface of the storage cylinder 23. A prompting ring 25 is slidably connected to the inner wall of the adjusting shell 21. A roller 26 is rotatably connected to one end of the prompting ring 25 near the inclined plate 24. A spring 27 is sleeved on the outer wall of the prompting ring 25. Through grooves are evenly opened on the outer wall of the storage cylinder 23. Zeolite strips are placed inside the storage cylinder 23. The adjusting shell 21 is a telescopic structure. The prompting ring 25 is installed at the non-telescopic position of the adjusting shell 21. A sliding groove is opened on the adjusting shell 21 corresponding to the position of the prompting ring 25. The roller 26 is located on the movement path of the inclined plate 24. The two ends of the spring 27 are fixedly connected to the prompting ring 25 and the roller 26, respectively. Specifically, since a pressure valve 28 is installed on the top of the regulating shell 21, when the gas inside the regulating shell 21 exceeds the pressure value of the pressure valve 28, the pressure valve 28 will be automatically triggered, changing it from a closed state to an open state, so that the purified gas inside the regulating shell 21 can be discharged normally. The waste gas generated inside the pulverizer that automatically adsorbs and purifies polycarboxylate superplasticizer can effectively remove particulate matter, harmful gases and pollutants from the waste gas. The waste gas emission after purification treatment can reduce the concentration of pollutants in the atmosphere, reduce the negative impact on the environment, protect the atmospheric environment, and improve the living and working environment of operators and nearby residents. Please refer to Figure 6 and Figure 7 As shown, the filter anti-clogging mechanism 3 includes a fixed shaft 31 fixedly connected to the top of the rotating shaft 13. A slide rail 32 is installed above the fixed shaft 31. A crank rod 33 is fixedly connected to both the left and right ends of the slide rail 32. A positioning plate 34 is slidably connected to the outer wall of the crank rod 33. A limit ring 35 is fixedly connected to the lower surface of the positioning plate 34. The limit ring 35 is fixedly connected to the inner wall of the processing cylinder 12. A filter plate 36 is fixedly connected above the crank rod 33. A cylindrical protrusion is fixedly connected at an eccentric position above the fixed shaft 31. The slide rail 32 and the fixed shaft 31 are slidably connected through the cylindrical protrusion. The crank rod 33 is L-shaped in general. The surface of the filter plate 36 is uniformly provided with arc grooves. Specifically, this can prevent blockages caused by impurities in the raw materials or adhesion between particles when the biomass polycarboxylate superplasticizer pulverizer is working. This increases the permeability between particles, preventing the raw materials from getting stuck or blocked during processing. Furthermore, preventing internal blockages ensures the continuous and efficient operation of the biomass polycarboxylate superplasticizer pulverizer, avoiding reduced production efficiency and increased maintenance and cleaning frequency due to internal blockages. In addition, it can prevent additional loads on the equipment caused by blockages, which can easily lead to wear and damage. By moving the filter plate 36, the load on the equipment can be reduced, extending the service life of the equipment.

[0019] Second Embodiment A powdering process for a polycarboxylate superplasticizer, including... S1, Raw material preparation, the main raw materials include polycarboxylate ether monomers, stabilizers and additives; S2, reaction synthesis, involves mixing polycarboxylic acid ether monomers and auxiliary materials in a certain proportion and carrying out a polycondensation reaction at a set temperature to generate polycarboxylic acid ether polymers; S3, Drying treatment: The polycarboxylic acid ether polymer synthesized by the reaction is dried to remove residual solvent and moisture. The dried product needs to be pulverized to obtain a uniform powder. S4, Crushing and Sieving: The dried polycarboxylate ether polymer is crushed by crushing equipment to obtain uniform powder. The crushed powder is then sieved to ensure consistent particle size. S5. Packaging and Storage: The crushed and sieved polycarboxylate superplasticizer powder is packaged and stored in a dry, ventilated environment to prevent moisture absorption and clumping.

[0020] The following are the complete usage steps and working principle of the above embodiments: This device is mainly used for: The pulverizing machine for polycarboxylate superplasticizers is primarily used to dry liquid or semi-solid polycarboxylate superplasticizers and convert them into powder or granular products for easy storage, transportation, and use. It improves product stability and consistency through efficient drying technology, adapts to special engineering needs, enhances concrete performance, and also has environmental and energy-saving advantages, making it an indispensable piece of equipment in modern concrete technology.

[0021] The waste gas treatment unit 2, which generates waste gas during the purification treatment process (purification treatment cylinder 12), is used in the following ways: When workers use the polycarboxylate superplasticizer pulverizer to process raw materials, the raw materials are continuously fed into the interior of the processing cylinder 12 through the feed port opened on the outside of the processing cylinder 12. However, during the operation of the biomass polycarboxylate superplasticizer pulverizer, the polycarboxylate superplasticizer undergoes pyrolysis. During the pH adjustment process and the pyrolysis of internal additives, anti-caking agents (such as calcium stearate) may decompose at high temperatures to generate CO2 or low-molecular-weight organic matter. Silicate modifiers are generally stable, but sulfur / chlorine-containing additives may produce acidic gases such as SO2 and HCl, which can cause the organic matter in the biomass to decompose at high temperatures, producing gases such as carbon monoxide and carbon dioxide. Since the processing cylinder 12 is installed above the processing cylinder 12, the exhaust gas generated inside the polycarboxylate superplasticizer pulverizer during normal use will drift upwards into the interior of the regulating shell 21. Because the storage cylinder 23 is movably connected to the interior of the regulating shell 21 via the fixing plate 22, and the interior of the storage cylinder 23 is filled with sufficient zeolite strips, when the aforementioned exhaust gas drifts into the regulating shell 21, zeolite, being a porous mineral containing many tiny channels and pores of moderate size capable of accommodating molecules of different sizes, and with its surface typically possessing chemical functional groups such as oxygen and hydroxyl groups, can chemically interact with gas molecules, enhancing the adsorption effect. For gases such as carbon monoxide and carbon dioxide, van der Waals forces and hydrogen bonds may interact with the chemical functional groups on the zeolite surface, causing the gas to be adsorbed onto the zeolite surface. Zeolite is a good adsorbent, capable of adsorbing gas molecules on its surface and within its pores through physical adsorption. Therefore, when the waste gas generated inside the polycarboxylate superplasticizer pulverizer passes through the storage cylinder 23, the zeolite inside the storage cylinder 23 will automatically adsorb pollutants in the waste gas. Since a pressure valve 28 is installed above the regulating shell 21, when the gas inside the regulating shell 21 exceeds the pressure value of the pressure valve 28, the pressure valve 28 will be automatically triggered, changing it from a closed state to an open state, thereby allowing the purified gas inside the regulating shell 21 to be discharged normally. The automatic adsorption and purification of the waste gas generated inside the polycarboxylate superplasticizer pulverizer can effectively remove particulate matter, harmful gases, and pollutants from the waste gas. The purified waste gas emission can reduce the concentration of pollutants in the atmosphere, reduce the negative impact on the environment, protect the atmospheric environment, and improve the living and working environment of operators and nearby residents. During the operation of the polycarboxylate superplasticizer pulverizer, the zeolite inside the storage cylinder 23 is constantly adsorbing and purifying waste gas. Waste molecules enter its porous structure and adhere to its surface. Therefore, after prolonged adsorption of waste gas, the weight of the zeolite gradually increases, and its adsorption capacity gradually weakens. As the weight of the zeolite inside the storage cylinder 23 increases, the inclined plate 24 fixedly connected to the lower surface of the storage cylinder 23 moves downwards synchronously. At this time, the downward-moving inclined plate 24 continuously squeezes the roller 26. When the adsorption capacity inside the storage cylinder 23 is insufficient to purify the waste gas, the storage cylinder 23 will stop moving downwards, and a warning signal will be displayed. The 25 ring slides out completely from inside the regulating shell 21. When the staff checks the working status of the polycarboxylate superplasticizer pulverizer, the exposed indicator ring 25 can promptly indicate that the zeolite is in a failure state. By observing the state of the indicator ring 25, insufficient zeolite adsorption capacity can be detected in time, and measures can be taken before the problem worsens to avoid greater losses due to equipment performance degradation. This helps to reduce operation and maintenance costs and repair expenses. Furthermore, timely detection of insufficient adsorption capacity can prompt staff to perform maintenance, regeneration, or replacement of zeolite to maintain the efficient operation of the equipment, which helps to maintain the stability and efficiency of the waste gas treatment system. Since the regulating shell 21 is a retractable and adjustable structure, when the staff finds that the zeolite has failed by observing the indicator ring 25, they should first turn off the pulverizer of the polycarboxylate superplasticizer to stop it from running, and then slide the regulating shell 21 upwards to change the regulating shell 21 from the sealed state to the open state, so that the staff can replace the storage cylinder 23 later. The filter anti-clogging mechanism 3, used for automatic shaking to prevent material blockage inside the processing cylinder 12, is specifically used as follows: When the polycarboxylate superplasticizer pulverizer is initially in normal operation, the rotating shaft 13 inside the processing cylinder 12 will continuously rotate, crushing and discharging the untreated biomass raw materials. Since a fixed shaft 31 is fixedly connected above the rotating shaft 13, the fixed shaft 31 will rotate synchronously with it during normal rotation. Because a cylindrical protrusion is provided at an eccentric position above the fixed shaft 31, the cylindrical protrusion above the fixed shaft 31 will continuously press against the inner wall of the slide rail 32 during rotation, causing the slide rail 32 to reciprocate linearly along the inner wall of the positioning plate 34. Since a filter plate 36 is fixedly connected above the curved rod 33, during normal operation of the polycarboxylate superplasticizer pulverizer, the filter plate 36 located inside... The filter plate 36 of the part will continuously reciprocate linearly with the crank 33. Through the reciprocating movement of the filter plate 36, the pulverizer of biomass polycarboxylate superplasticizer can avoid blockage caused by impurities in the raw materials or adhesion between particles during operation. This can increase the permeability between particles, prevent the raw materials from getting stuck or blocked during processing, and prevent internal blockage. It can also ensure the continuous and efficient operation of the pulverizer of biomass polycarboxylate superplasticizer, avoid reducing production efficiency due to internal blockage, and avoid increasing the frequency of maintenance and cleaning. In addition, it can also avoid the extra load caused by blockage during equipment operation, which can easily cause wear and damage to the equipment. The movement of the filter plate 36 can reduce the load on the equipment and extend the service life of the equipment.
