Description

Technical Field

[0001] The utility model relates to the field of filling, in particular to an anti-drip filling head for water reducing agent filling. Background Art

[0002] In the construction industry, the use of water reducing agents plays a crucial role in improving the performance of concrete. With the continuous improvement of the quality requirements for concrete in the construction industry, as well as the increasing emphasis on environmental protection and cost control, the emergence of an anti-drip filling head for water reducing agent filling is of great significance.

[0003] However, for traditional anti-drip filling heads for water reducing agent filling, after long-term use, the sealing components may be worn or aged, resulting in a decline in the anti-drip performance and drip leakage. Due to the complex composition of water reducing agents, impurities may accumulate inside the filling head, causing blockages and affecting the filling efficiency. The complex structure makes the cleaning and maintenance work cumbersome, increasing the maintenance cost and downtime.

[0004] Therefore, aiming at the problems of easy blockage, difficult cleaning, and frequent maintenance of the traditional anti-drip filling head for water reducing agent filling, an anti-drip filling head for water reducing agent filling can be designed. By adding a primary filter screen, a secondary filter screen, a tertiary filter screen, and a material removal plate, the filtration effect of the water reducing agent is significantly improved, avoiding the influence of impurities on the filling head and subsequent use processes, reducing the risk of blockage of the filling head, improving the fluency and stability of filling. The good filtration effect and impurity removal function can also reduce the wear and corrosion inside the filling head. The reduction of impurities reduces the damage to the internal components of the filling head, extends the service life of the filling head, and reduces the frequency of replacement and repair. Summary of the Utility Model

[0005] In order to overcome the problems of easy blockage, difficult cleaning, and frequent maintenance of the traditional anti-drip filling head for water reducing agent filling.

[0006] The technical solution of the utility model is: an anti-drip filling head for water reducing agent filling, including a filling pipeline, a one-way ball valve, a funnel, a primary filter screen, a liquid storage cylinder, and a liquid sensor. A one-way ball valve for outputting water reducing agent is installed on the left side of the filling pipeline. A liquid sensor for intelligently controlling the one-way ball valve is arranged on the left side of the one-way ball valve. A liquid storage cylinder for recycling water reducing agent is installed in front of the liquid sensor. The right side of the filling pipeline is movably connected to a funnel for increasing the entry of water reducing agent. A primary filter screen for screening water reducing agent is arranged inside the funnel. A material removal assembly is arranged inside the filling pipeline.

[0007] Preferably, through the added primary filter screen, secondary filter screen, tertiary filter screen and material removal plate, the filtering effect of the water reducing agent is significantly improved, the influence of impurities on the filling head and the subsequent use process is avoided, the risk of filling head blockage is reduced, the fluency and stability of filling are improved. The good filtering effect and impurity removal function can also reduce the wear and corrosion inside the filling head. The reduction of impurities reduces the damage to the internal components of the filling head, extends the service life of the filling head, and reduces the frequency of replacement and maintenance.

[0008] As a preference, for the filling pipeline, groove and first mounting plate, the first mounting plate with a connection hole is fixedly connected to the left side of the filling pipeline. A groove surrounding the filling pipeline is formed on the surface of the filling pipeline. The inside of the filling pipeline is polished with high precision. The high-precision polishing can reduce the residue of the water reducing agent in the pipeline, avoid dripping and waste caused by the residual liquid. The smooth inner wall is not easy to adhere to impurities and dirt, which is convenient for cleaning and maintenance, keeps the filling pipeline hygienic and pure, and ensures that the quality of the water reducing agent is not affected.

[0009] As a preference, for the funnel, primary filter screen, secondary filter screen and tertiary filter screen, the smooth-surfaced primary filter screen, secondary filter screen and tertiary filter screen are installed horizontally and equidistantly step by step inside the funnel. The design of the funnel helps to concentrate and guide the flow of the water reducing agent, making the filling process smoother and reducing the possibility of liquid splashing and overflowing. The primary filter screen, secondary filter screen and tertiary filter screen arranged step by step can achieve gradual and fine filtration of the water reducing agent. The primary filter screen can first intercept larger impurity particles, and the secondary filter screen and tertiary filter screen can further remove smaller impurities, thus greatly improving the purity of the water reducing agent. The smooth surface reduces the adhesion and accumulation of impurities on the filter screen surface.

[0010] As a preference, the connecting sleeve is installed on the left side of the funnel and the right side of the filling pipeline. The connecting sleeve is made of polytetrafluoroethylene material. Polytetrafluoroethylene has excellent chemical corrosion resistance and can effectively resist the erosion of various chemical substances in the water reducing agent, ensuring that the connecting sleeve will not be damaged due to chemical corrosion during long-term use, thus maintaining good sealing performance and reducing the risk of dripping.

[0011] As a preference, the material removal assembly includes a sliding track, a self-driven roller, an L-shaped connecting rod, a material removal plate and a straight connecting rod. The sliding track is installed inside the connecting sleeve. A self-driven roller is arranged inside the sliding track. The bottom of the self-driven roller is connected to the L-shaped connecting rod inserted into the hole formed on the right side surface of the material removal plate. The straight connecting rod can be inserted into the corresponding hole position in the L-shaped connecting rod. The cooperation of the sliding track and the self-driven roller makes the movement of the material removal plate smoother and more precise. The connection mode of the L-shaped connecting rod and the straight connecting rod provides a reliable transmission mechanism for the action of the material removal plate. The material removal plate can prevent impurities from accumulating in the pipeline for a long time.

[0012] Preferably, a one-way ball valve, a liquid sensor, a second mounting plate, rivets and a discharge cylinder are provided. The first mounting plate is movably connected to the second mounting plate through the rivets. The gap between the first mounting plate and the second mounting plate is filled with polyethylene material. The one-way ball valve is fixedly connected to the left side of the second mounting plate. A handle for switching is provided in front of the one-way ball valve. The discharge cylinder is installed on the left side of the one-way ball valve. A liquid sensor is arranged inside the discharge cylinder. The liquid sensor can monitor in real time parameters such as the flow rate and pressure of the flowing water reducer, which helps to accurately control the filling volume and timely detect abnormal situations during the filling process, such as too large or too small flow rate, so as to take corresponding measures for adjustment, improve the filling accuracy and quality, ensure that the liquid only flows out in the direction of the discharge cylinder, prevent backflow, and thus help to maintain the accuracy and stability of filling.

[0013] Preferably, a liquid storage cylinder and a cover plate are provided. The liquid storage cylinder is installed in front of the discharge cylinder. The liquid storage cylinder and the discharge cylinder form a 45° angle. The cover plate is installed directly in front of the liquid storage cylinder. In the case of rapid filling, the liquid storage cylinder can absorb excess liquid to avoid liquid overflow; at the end of filling, a small amount of liquid remaining in the liquid storage cylinder can pass through the holes opened in the cover plate into the external plastic hose for reflux absorption treatment, so that the excess water reducer will not be contaminated.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. The added primary filter screen, secondary filter screen, tertiary filter screen and material removal plate significantly improve the filtering effect of the water reducer, avoid the influence of impurities on the filling head and subsequent use process, reduce the risk of filling head blockage, improve the filling smoothness and stability. The good filtering effect and impurity removal function can also reduce the wear and corrosion inside the filling head. The reduction of impurities reduces the damage to the internal components of the filling head, extends the service life of the filling head, and reduces the frequency of replacement and maintenance;

[0016] 2. High-precision polishing can reduce the residue of the water reducer in the pipeline, avoid dripping and waste caused by the residual liquid. The smooth inner wall is not easy to adhere to impurities and dirt, which is convenient for cleaning and maintenance, keeps the filling pipeline hygienic and pure, and ensures that the quality of the water reducer is not affected;

[0017] 3. The design of the funnel helps to concentrate and guide the flow of the water reducer, makes the filling process smoother, reduces the possibility of liquid splashing and overflow. The primary filter screen, secondary filter screen and tertiary filter screen set step by step can achieve gradual and fine filtration of the water reducer. The primary filter screen can first intercept larger impurity particles, and the secondary filter screen and tertiary filter screen can further remove smaller impurities, thus greatly improving the purity of the water reducer. The smooth surface reduces the adhesion and accumulation of impurities on the filter screen surface;

[0018] 4. The bottom of the self-driven roller is connected to an L-shaped connecting rod inserted into a hole opened on the right surface of the material removal plate. The straight connecting rod can be inserted into the corresponding hole position in the L-shaped connecting rod. The cooperation of the sliding track and the self-driven roller makes the movement of the material removal plate smoother and more precise. The connection method of the L-shaped connecting rod and the straight connecting rod provides a reliable transmission mechanism for the movement of the material removal plate, and the material removal plate can prevent impurities from accumulating in the pipeline for a long time.

The primary filter screen 3 can first intercept larger impurity particles, and the secondary filter screen 9 and the tertiary filter screen 10 can further remove smaller impurities, thus greatly improving the purity of the water reducing agent. The smooth surface reduces the adhesion and accumulation of impurities on the filter screen surface. The connecting sleeve 11 is installed on the left side of the funnel 2 and the right side of the filling pipeline 1. The connecting sleeve 11 is made of polytetrafluoroethylene material.

[0028] Please refer to Figures 4 - 6, in this embodiment, the material removing assembly includes a sliding track 12, a self-driven roller 13, an L-shaped connecting rod 14, a material removing plate 15 and a straight connecting rod 16. The sliding track 12 is installed inside the connecting sleeve 11. A self-driven roller 13 is arranged inside the sliding track 12. The bottom of the self-driven roller 13 is connected to an L-shaped connecting rod 14 inserted into a hole opened on the right side surface of the material removing plate 15. The straight connecting rod 16 can be inserted into a corresponding hole position inside the L-shaped connecting rod 14. The cooperation between the sliding track 12 and the self-driven roller 13 makes the movement of the material removing plate 15 smoother and more accurate. The connection mode of the L-shaped connecting rod 14 and the straight connecting rod 16 provides a reliable transmission mechanism for the movement of the material removing plate 15. The material removing plate 15 can prevent impurities from accumulating in the pipeline for a long time. A one-way ball valve 4, a liquid sensor 6, a second mounting plate 17, rivets 18 and a discharge cylinder 19. The first mounting plate 8 is movably connected to the second mounting plate 17 through the rivets 18. The gap between the first mounting plate 8 and the second mounting plate 17 is filled with a polyethylene material. The one-way ball valve 4 is fixedly connected to the left side of the second mounting plate 17. A handle for switching is arranged in front of the one-way ball valve 4. The discharge cylinder 19 is installed on the left side of the one-way ball valve 4. A liquid sensor 6 is arranged inside the discharge cylinder 19. The liquid sensor 6 can monitor parameters such as the flow rate and pressure of the flowing water reducing agent in real time. This helps to accurately control the filling volume and timely detect abnormal situations during the filling process, such as too large or too small flow rate, so as to take corresponding measures for adjustment, improve the filling accuracy and quality, and ensure that the liquid only flows out in the direction of the discharge cylinder 19, preventing backflow, thus helping to maintain the accuracy and stability of filling. A liquid storage cylinder 5 and a cover plate 20. The liquid storage cylinder 5 is installed in front of the discharge cylinder 19. The liquid storage cylinder 5 and the discharge cylinder 19 form a 45° angle. The cover plate 20 is installed directly in front of the liquid storage cylinder 5. In the case of rapid filling, the liquid storage cylinder 5 can absorb excess liquid to avoid liquid overflow; at the end of filling, a small amount of liquid remaining in the liquid storage cylinder 5 can pass through the holes opened in the cover plate 20 and be connected to an external plastic hose for reflux absorption treatment, so that the excess water reducing agent will not be contaminated.

[0029] When working, the water reducing agent is filtered by the primary filter screen 3, the secondary filter screen 9 and the tertiary filter screen 10 in the funnel 2. When the filtered water reducing agent enters the filling pipeline 1 connected to the connecting sleeve 11, the self-driven roller 13 in the sliding track 12 starts to move through the induction module inside the L-shaped connecting rod 14 when it senses the water reducing agent. The self-driven roller 13 drives the material removing plate 15 to rotate through the L-shaped connecting rod 14 and the straight connecting rod 16. After the water reducing agent passes through the filling pipeline 1, the operator opens the one-way ball valve 4 to fill the water reducing agent through the discharge cylinder 19. The liquid sensor 6 checks the flow rate of the water reducing agent. When part of the water reducing agent that enters the liquid storage cylinder 5 will be recovered through the holes opened in the cover plate 20 and the connection of external equipment. After filling is completed, the operator closes the one-way ball valve 4 through the handle.

[0030] Through the above steps, the water reducing agent passes through the primary filter screen 3, secondary filter screen 9, tertiary filter screen 10 and the material removing plate 15 in the funnel 2, significantly improving the filtering effect of the water reducing agent, avoiding the influence of impurities on the filling head and the subsequent use process, reducing the risk of clogging of the filling head, improving the fluency and stability of filling. When the self-driven roller 13 in the sliding track 12 senses the water reducing agent through the induction module inside the L-shaped connecting rod 14, it starts to move. The self-driven roller 13 drives the material removing plate 15 to rotate through the L-shaped connecting rod 14 and the straight connecting rod 16, reducing the wear and corrosion inside the filling head. The reduction of impurities reduces the damage to the internal components of the filling head, extends the service life of the filling head, and reduces the frequency of replacement and maintenance to solve the problems of easy clogging, difficult cleaning and frequent maintenance of the traditional anti-drip filling head for water reducing agent filling.

[0031] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present invention.
