Description

Technical Field

[0001] This utility model relates to the technical field of cement grinding aid production equipment, specifically a cement raw material grinding aid production and dilution equipment. Background Technology

[0002] Cement grinding aids are chemical additives that improve the grinding effect and performance of cement. They can significantly increase cement hourly output, cement strength at various ages, and improve its fluidity. Cement grinding aids can substantially reduce the electrostatic adsorption and balling phenomenon formed during the grinding process and reduce the tendency for ultrafine particles to re-agglomerate. Cement grinding aids can also significantly improve cement fluidity, enhance the grinding effect of the mill and the classifier efficiency, thereby reducing grinding energy consumption.

[0003] After purchasing the raw materials for liquid cement grinding aids, they need to be diluted according to requirements before use. After the raw materials are loaded into the dilution tank, the dilution process is accelerated by continuous stirring and water replenishment. However, traditional dilution equipment often uses straight blades or ordinary spiral blades in its stirring mechanism, with a certain gap between the blades and the inner wall of the dilution tank, and the stirring trajectory is relatively fixed. When mixing the grinding aid concentrate with dilution water, the concentrate usually has a certain viscosity, easily adhering to the inner wall of the dilution tank. Existing stirring structures cannot effectively clean the concentrate adhering to the inner wall. This not only wastes the concentrate but also causes the residual concentrate to mix with subsequently added raw materials, leading to deviations in the final diluted solution concentration and affecting the stability of the grinding aid product quality. Furthermore, it requires regular shutdowns for manual cleaning of the tank inner wall, severely reducing the equipment's operating efficiency. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a cement raw material grinding aid production dilution equipment. It features the advantages of achieving uniform mixing of the diluted solution, precise and controllable concentration, eliminating the need for additional manual cleaning of the inner wall of the dilution tank, improving equipment operating efficiency, and enhancing cooling or heating effects. This ensures the stability and economy of the cement raw material grinding aid dilution process. It solves the problems of traditional mixing methods, such as bottom sedimentation, grinding aid concentrate adhering to the inner wall of the tank leading to dilution concentration deviation, cumbersome manual cleaning of the inner wall of the tank, low equipment operating efficiency, and poor cooling or heating effects.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a cement raw material grinding aid production dilution equipment, comprising a dilution tank, wherein a feeding port is provided at the top of the dilution tank, a discharge port is provided at the bottom of the dilution tank, and a stirring mechanism is provided inside the dilution tank, wherein the stirring mechanism includes: The motor is fixedly mounted on the dilution tank; A rotating shaft is fixedly connected to the output end of the motor; A connecting rod, one end of which is fixedly connected to the periphery of the rotating shaft; A spiral blade is fixedly connected to the other end of the connecting rod, and the outer wall of the spiral blade is in contact with the inner wall of the dilution tank.

[0006] It should be noted that after the stock solution and dilution water are fed into the dilution tank through the feeding port, the feeding port is closed, the motor is turned on, and the rotating shaft is driven to rotate. This drives the connecting rod and the spiral blades to rotate, so that the spiral blades can transfer the raw materials at the bottom of the dilution tank to the top for secondary stirring. This reduces the precipitation of reactants at the bottom of the dilution tank and can also scrape off the stock solution adhering to the inner wall of the dilution tank, thus cleaning the inner wall of the dilution tank. The motor is equipped with a speed control controller, which can adjust the output speed of the motor according to the concentration of the original solution and the dilution process requirements, thereby changing the rotation speed of the rotating shaft and the spiral blades.

[0007] Preferably, the outer wall of the dilution tank is provided with a jacket, which has a double-layer structure. The inner wall of the jacket and the outer wall of the dilution tank form a water-cooling cavity, and the hollow area between the outer wall and the inner wall of the jacket forms a cooling cavity. The bottom of the water-cooling cavity is connected to a water inlet pipe, and the top of the water-cooling cavity is connected to a water outlet pipe. The top of the cooling cavity is provided with a steam inlet pipe, one end of which is connected to the inside of the dilution tank and the other end is connected to the inside of the cooling cavity, so as to realize the transportation of water vapor from the dilution tank to the cooling cavity. A water pump is fixedly installed at the bottom of the cooling cavity. The water inlet of the water pump is connected to the bottom of the cooling cavity to draw condensed water, and the liquid outlet pipe of the water pump is connected to the inside of the dilution tank.

[0008] It should be noted that injecting cold or hot water into the water-cooling chamber through the water inlet pipe can cool or heat the diluent inside the dilution tank according to the dilution process requirements, in order to achieve the best dilution effect in conjunction with the stirring process. When cooling or water vapor recovery is required, cold water is introduced into the water-cooling chamber. If the temperature inside the dilution tank is too high during stirring, the water in the tank may evaporate. The generated water vapor can enter the cooling chamber through the steam inlet pipe. The cold water in the water-cooling chamber exchanges heat with the cooling chamber, causing the water vapor in the cooling chamber to cool down and condense into liquid water. This liquid water can be pumped back into the dilution tank through the liquid outlet pipe to ensure that the concentration of the diluted solution meets the process requirements. The inlet and outlet pipes can be connected to external constant temperature water supply equipment to form a circulation of hot and cold water in the water-cooled chamber, so as to continuously and stably control the internal temperature of the dilution tank.

[0009] Preferably, a one-way valve is provided on the steam inlet pipe, and the one-way valve is directed from the inside of the dilution tank to the cooling chamber.

[0010] Preferably, the feeding port of the dilution tank is provided with a sealing cover, and a rubber sealing ring is fixedly provided on the contact surface between the sealing cover and the feeding port. One side of the sealing cover is rotatably connected to the top of the dilution tank by a hinge, and the other side is detachably fixedly connected to the top of the dilution tank by a buckle. The sealing cover can prevent the diluent from splashing out during the stirring process, and the rubber sealing ring can enhance the sealing of the feeding port and prevent external impurities from entering the dilution tank and affecting the purity of the diluent.

[0011] Preferably, a filter assembly is provided at the feeding port of the dilution tank. The filter assembly includes a filter screen support fixed to the inner wall of the feeding port and a metal filter screen detachably installed on the filter screen support. The filter assembly can filter the added grinding aid stock solution and dilution water to remove solid impurities or incompletely dissolved particles that may be present in the stock solution and dilution water. The detachable design of the metal filter screen facilitates regular cleaning or replacement to ensure the purity of the fed stock solution.

[0012] Preferably, the discharge port is provided with a detachable filter screen, which can remove impurities from the solution after stirring.

[0013] Preferably, the bottom of the dilution tank is fixedly connected to several support frames, and the bottom of the support frames is provided with foot pads made of rubber.

[0014] Furthermore, a temperature sensor is fixedly installed on the inner wall of the dilution tank. The signal output terminal of the temperature sensor is electrically connected to an external controller. The external controller is connected to the solenoid valves on the inlet pipe, the outlet pipe, and the external constant temperature water supply equipment. The temperature sensor can monitor the temperature of the diluent in the dilution tank in real time and transmit the temperature signal to the external controller. When the monitored temperature is higher than the upper limit of the process set temperature, the external controller controls the solenoid valve on the inlet pipe to increase the cold water input and the solenoid valve on the outlet pipe to speed up the hot water discharge. At the same time, it adjusts the external constant temperature water supply equipment to lower the water supply temperature. When the monitored temperature is lower than the lower limit of the process set temperature, the external controller adjusts the valves and water supply equipment in the opposite direction to realize automatic closed-loop control of the temperature in the dilution tank. Furthermore, an observation window is provided on the side wall of the dilution tank. The observation window is made of tempered glass that is resistant to high temperature and corrosion, and a removable dust cover is provided on the outside of the observation window. The staff can observe the stirring status, liquid level and any abnormal sedimentation in the dilution tank in real time through the observation window. The dust cover can prevent dust from accumulating on the glass surface and affecting the observation, while also protecting the observation window from external impact damage.

At the same time, the operator can flexibly adjust the rotation speed of the spiral blades according to the concentrate concentration and dilution process requirements through the speed control controller to adapt to the stirring needs under different working conditions, ultimately achieving uniform mixing of the diluted solution, precise and controllable concentration, and no need for additional manual cleaning of the inner wall of the dilution tank, improving equipment operating efficiency and ensuring the stability and economy of the cement raw material grinding aid dilution process; Third, when the outer wall of the dilution tank transfers heat to the dilution tank, the material adhering to the inner wall of the dilution tank can absorb or release heat more quickly, enhancing the cooling or heating effect.

[0016] 2. This cement raw material grinding aid production dilution equipment achieves multiple functions through a double-layer jacket on the outer wall of the dilution tank, coupled with an inlet water pipe, an outlet water pipe, a steam inlet pipe with a one-way valve, and a return water pump at the bottom of the cooling chamber: First, by introducing cold / hot water into the water-cooling chamber, the diluent in the tank can be cooled or heated as needed to meet the temperature requirements of different dilution processes; second, when the temperature inside the tank is too high and water evaporates, the water vapor enters the cooling chamber through the one-way valve, condenses into liquid water by the cooling capacity of the water-cooling chamber, and then flows back into the tank through the water pump, avoiding water loss that affects the concentration; ultimately, it achieves precise and stable temperature control inside the dilution tank, zero waste recovery of water vapor, and the diluent concentration always meeting the process standards, reducing raw material loss and improving the consistency of grinding aid production quality.

[0031] It should be noted that after the stock solution and dilution water are fed into the dilution tank 100 through the feed port 120, the feed port 120 is closed, the motor 210 is turned on, and the rotating shaft 220 is rotated, which in turn drives the connecting rod 230 and the spiral blade 240 to rotate. This allows the spiral blade 240 to transfer the raw material at the bottom of the dilution tank 100 to the top for secondary stirring, reducing the precipitation of reactants at the bottom of the dilution tank 100, and also scraping off the stock solution adhering to the inner wall of the dilution tank 100, which can clean the inner wall of the dilution tank 100. Among them, the motor 210 is equipped with a speed regulation controller, which can adjust the output speed of the motor 210 according to the concentration of the original solution and the dilution process requirements, thereby changing the rotation speed of the rotating shaft 220 and the spiral blade 240.

[0032] In an optional embodiment, the outer wall of the dilution tank 100 is provided with a jacket 300, which has a double-layer structure. The inner wall of the jacket and the outer wall of the dilution tank form a water-cooling cavity, and the hollow area between the outer wall of the jacket and the inner wall of the jacket forms a cooling cavity. The bottom of the water-cooling cavity 320 is connected to a water inlet pipe 321, and the top of the water-cooling cavity 320 is connected to a water outlet pipe 322. The top of the cooling cavity 310 is provided with a steam inlet pipe 311. One end of the steam inlet pipe 311 is connected to the inside of the dilution tank 100, and the other end is connected to the inside of the cooling cavity 310, so as to realize the transportation of water vapor from the dilution tank to the cooling cavity. A water pump 312 is fixedly installed at the bottom of the cooling cavity 310. The water inlet of the water pump 312 is connected to the bottom of the cooling cavity 310 to draw condensed water. The liquid outlet pipe 313 of the water pump 312 is connected to the inside of the dilution tank 100.

[0033] It should be noted that injecting cold or hot water into the water-cooling chamber 320 through the water inlet pipe 321 can cool or heat the diluent inside the dilution tank 100 according to the dilution process requirements, in order to achieve the best dilution effect in conjunction with the stirring process. When cooling or water vapor recovery is required, cold water is introduced into the water-cooling chamber 320. If the temperature inside the dilution tank 100 is too high during stirring, the water in the tank may evaporate. The generated water vapor can enter the cooling chamber 310 through the steam inlet pipe 311. The cold water in the water-cooling chamber 320 exchanges heat with the cooling chamber 310, causing the water vapor in the cooling chamber to cool down and condense into liquid water. This liquid water can be pumped back into the dilution tank 100 by the water pump 312 through the liquid outlet pipe 313, ensuring that the concentration of the diluted solution meets the process requirements. The inlet pipe 321 and outlet pipe 322 can be connected to an external constant temperature water supply device to form a circulation of hot and cold water in the water-cooled chamber 320, so as to continuously and stably control the internal temperature of the dilution tank 100.

A rubber sealing ring is fixedly provided on the contact surface between the sealing cover and the feeding port 120. One side of the sealing cover is rotatably connected to the top of the dilution tank 100 via a hinge, and the other side is detachably fixedly connected to the top of the dilution tank 100 via a snap fastener. The sealing cover can prevent the diluent from splashing out during the stirring process, and the rubber sealing ring can enhance the sealing performance of the feeding port 120 and prevent external impurities from entering the dilution tank 100 and affecting the purity of the diluent.

[0036] In an optional embodiment, a filter assembly is provided at the feed port 120 of the dilution tank 100. The filter assembly includes a filter screen support fixed to the inner wall of the feed port 120 and a metal filter screen that can be detachably installed on the filter screen support. The filter assembly can filter the added grinding aid stock solution and dilution water to remove solid impurities or incompletely dissolved particles that may be present in the stock solution and dilution water. The detachable design of the metal filter screen facilitates regular cleaning or replacement to ensure the purity of the feed stock solution.

[0037] In an optional embodiment, a removable filter screen 131 is provided on the outlet 130, which can remove impurities from the solution after stirring.

[0038] In an optional embodiment, a plurality of support frames 110 are fixedly connected to the bottom of the dilution tank 100, and the bottom of the support frame 110 is provided with foot pads made of rubber.

[0039] Furthermore, a temperature sensor is fixedly installed on the inner wall of the dilution tank 100. The signal output terminal of the temperature sensor is electrically connected to an external controller. The external controller is connected to the solenoid valve on the inlet pipe 321, the solenoid valve on the outlet pipe 322, and the external constant temperature water supply equipment. The temperature sensor can monitor the temperature of the diluent in the dilution tank 100 in real time and transmit the temperature signal to the external controller. When the monitored temperature is higher than the upper limit of the process set temperature, the external controller controls the solenoid valve on the inlet pipe 321 to increase the cold water input and the solenoid valve on the outlet pipe 322 to speed up the hot water discharge. At the same time, it adjusts the external constant temperature water supply equipment to lower the water supply temperature. When the monitored temperature is lower than the lower limit of the process set temperature, the external controller adjusts the valves and water supply equipment in the opposite direction to realize automatic closed-loop control of the temperature in the dilution tank 100. Furthermore, an observation window is provided on the side wall of the dilution tank 100. The observation window is made of tempered glass that is resistant to high temperature and corrosion. A removable dust cover is provided on the outside of the observation window. The staff can observe the stirring status, liquid level and whether there is any abnormal sedimentation in the dilution tank 100 in real time through the observation window. The dust cover can prevent dust from accumulating on the glass surface and affecting the observation, while protecting the observation window from external impact damage.

[0040] Working Principle: The working principle of this cement raw material grinding aid production and dilution equipment is as follows: During operation, the grinding aid concentrate and dilution water are first filtered through the filter assembly at the feeding port 120 and then fed into the dilution tank 100. The sealing cover with the rubber sealing ring is closed to ensure a seal. The stirring mechanism 200 is started, and the rotating shaft 220 is driven to rotate by the motor 210 equipped with a speed regulation controller, which drives the connecting rod 230 and the spiral blades 240 that are attached to the inner wall of the tank to rotate. On the one hand, the raw materials at the bottom of the tank are transferred to the top for secondary stirring to avoid sedimentation at the bottom. On the other hand, the residual concentrate on the inner wall of the tank is scraped off. At the same time, the speed of the motor 210 can be adjusted according to the concentrate concentration and process requirements to ensure uniform mixing. During the process, the double-layer jacket 3 on the outer wall of the tank... Working in concert, the system supplies cold / hot water to the water-cooling chamber 320 via the inlet pipe 321. Combined with the automatic closed-loop control of the internal temperature sensor and the external controller, it adjusts the water temperature and flow rate in real time to achieve precise temperature control of the diluent inside the tank. If the temperature inside the tank is too high, causing water evaporation, the water vapor enters the cooling chamber 310 through the steam inlet pipe 311 with a one-way valve. After being cooled and condensed into liquid water by the water-cooling chamber 320, it flows back into the tank through the outlet pipe 313 via the water pump 312 at the bottom of the cooling chamber 310, avoiding concentration deviation. After dilution is completed, the diluent that meets the process requirements is filtered again through the filter screen 131 at the outlet 130 and discharged. The state inside the tank can be monitored through the observation window throughout the process to ensure a stable and efficient dilution process.

[0041] In summary, this cement raw material grinding aid production and dilution equipment, by incorporating a stirring mechanism 200 within the dilution tank 100—comprising a motor 210, a rotating shaft 220, a connecting rod 230, and spiral blades 240 conforming to the inner wall of the tank—and equipping the motor 210 with a speed control controller, achieves two core functions: First, when the motor 210 drives the spiral blades 240 to rotate, it continuously transfers the raw material from the bottom of the dilution tank 100 to the top for secondary stirring, overcoming the bottom sedimentation problem that easily occurs with traditional stirring methods; second, the design of the spiral blades 240 conforming to the inner wall allows for simultaneous scraping away of the grinding aid concentrate adhering to the inner wall of the tank, preventing residue buildup. This reduces the deviation in dilution concentration caused by the residue. At the same time, the staff can flexibly adjust the rotation speed of the spiral blade 240 according to the original concentration and dilution process requirements through the speed adjustment controller to adapt to the stirring needs under different working conditions. Ultimately, the diluted liquid is mixed evenly and the concentration is accurately controllable. Moreover, the inner wall of the dilution tank 100 does not require additional manual cleaning, and the equipment operating efficiency is improved, ensuring the stability and economy of the cement raw material grinding aid dilution process. Thirdly, when the outer wall of the tank transfers heat to the dilution tank, the material adhering to the inner wall of the dilution tank 100 can absorb or release heat more quickly, enhancing the cooling or heating effect.

[0042] This cement raw material grinding aid production dilution equipment achieves multiple functions through a double-layer jacket 300 on the outer wall of the dilution tank 100, coupled with a water inlet pipe 321, a water outlet pipe 322, a steam inlet pipe 311 with a one-way valve, and a return water pump 312 at the bottom of the cooling chamber 310. Firstly, by introducing cold / hot water into the water-cooling chamber 320, the diluent in the tank can be cooled or heated as needed to meet the temperature requirements of different dilution processes. Secondly, when the temperature inside the tank is too high, causing water evaporation, the water vapor enters the cooling chamber 310 through the one-way valve, condenses into liquid water using the cooling capacity of the water-cooling chamber 320, and then flows back into the tank via the water pump 312, preventing water loss and ensuring the concentration remains consistent. Ultimately, this achieves precise and stable temperature control within the dilution tank 100, zero water vapor waste recovery, and a diluent concentration that always meets process standards, reducing raw material loss and improving the consistency of grinding aid production quality.
