Description

Technical Field

[0001] The utility model relates to the technical field of concrete admixture processing, in particular to a concrete admixture filling device. Background Art

[0002] The addition of admixtures plays a certain role in improving the performance of concrete. The purpose of adding concrete chemical admixtures is mainly to improve certain aspects of the performance of concrete mixtures or hardened concrete. Concrete admixture manufacturers mass-produce concrete admixtures and store them in storage tanks, and then fill and pack them into bags for sale. In order to improve the efficiency of filling, filling devices are now used for rapid filling.

[0003] According to a disclosed concrete admixture filling device (Announcement No.: CN220181143U), in the above application, the first air bag and the second air bag are inflated respectively by an air pump, so that the two expand and relatively seal the connection between the bag mouth and the filling pipe respectively. The small particles of admixture floating in the filling process cannot be dispersed into the external environment, which can effectively reduce the damage to the health of the workers.

[0004] However, in actual use of the above equipment, after the air bag seals the inside of the filling bag, when the admixture quickly enters the filling bag through the filling tube, dust will still be formed inside the filling bag due to the high-speed movement. When the seal inside the filling bag is released for unloading after the filling is completed, some of the flying dust will still fly into the outside air, causing environmental pollution. If the dust is waited for to fall completely, the processing progress will be affected. In view of this, we propose a concrete admixture filling device. Summary of the invention

[0026] The filling assembly includes: an electric push rod 501, a cylinder 505, a motor 509 and a retractable discharge pipe 511. The electric push rod 501 is fixedly installed on the inner top surface of the connecting cover 4. A hollow circular plate 502 is fixedly installed on the bottom end of the electric push rod 501. After the electric push rod 501 is started, it can drive the hollow circular plate 502 to move downward, so that the hollow circular plate 502 enters the interior of the filling bag. At this time, the hollow circular plate 502 can partially separate the internal space of the filling bag, block the flying dust during the filling process, reduce the degree of dust flying, and prevent the connecting cover 4 from quickly detaching from the filling bag after the filling is completed, so that the inside of the filling bag flies to the outside and affects the environment.

[0027] A circular hole 503 is provided on the upper surface of the hollow circular plate 502, and annular grooves 504 are provided at the upper and lower ends of the inner wall surface of the circular hole 503. The cylinder 505 is arranged at the inner center of the hollow circular plate 502, and sealing circular plates 506 are fixedly installed at the upper and lower ends of the cylinder 505. A sealing ring 507 is fixedly installed on the outer surface of the sealing circular plate 506. The two sealing rings 507 located at the upper and lower ends of the cylinder 505 are respectively slidably connected with the inner parts of the annular grooves 504 at the upper and lower ends of the circular hole 503. The cylinder 505 can be limited inside the circular hole 503 through the cooperation of the set annular groove 504, the sealing ring 507 and the sealing circular plate 506, and can rotate inside the circular hole 503. At the same time, the set sealing circular plate 506 can seal the interior of the hollow circular plate 502 to prevent dust from entering the interior of the hollow circular plate 502.

[0028] A large gear 508 is fixedly installed at the center of the cylinder 505, a motor 509 is fixedly installed on the left surface of the hollow circular plate 502, the bottom end of the motor 509 penetrates through the upper surface of the hollow circular plate 502 and a small gear 510 is fixedly installed, the tooth surface of the small gear 510 is meshed with the tooth surface of the large gear 508, when the motor 509 is started, the large gear 508 can be driven by the small gear 510 to rotate slowly, the retractable discharge pipe 511 is rotatably installed at the bottom of the front end of the filling machine 3, the bottom end of the retractable discharge pipe 511 penetrates through the sealing circular plate 506 and the upper surface of the large gear 508, the retractable discharge pipe 511 is connected to the sealing circular plate 506, and the large gear 508 is connected to the sealing circular plate 508. 6 is fixedly connected to the large gear 508. When the large gear 508 rotates, the retractable discharge pipe 511 can be driven to rotate synchronously. When the hollow circular plate 502 moves downward to the inside of the filling bag, the filling machine 3 can be started to fill the additive into the filling bag through the retractable discharge pipe 511. As the filling proceeds, the hollow circular plate 502 can be slowly lifted so that the bottom end of the retractable discharge pipe 511 always maintains a certain short distance from the surface of the additive inside the filling bag, thereby avoiding the retractable discharge pipe 511 being far away from the surface of the additive inside the filling bag, which may cause a large amount of dust to appear during the filling process.

[0029] During the filling process, the motor 509 can be started to drive the retractable discharge tube 511 to rotate, so that the additive can enter the interior of the filling bag evenly and completely, avoiding the additive being accumulated only in the inner center of the filling bag during filling, resulting in the need to shake the additive flat after the filling is completed, affecting the processing efficiency.

[0030] A fixed circular plate 601 is fixedly installed on the outer bottom end of the telescopic discharge tube 511, and a rubber ring 602 is fixedly installed on the upper surface of the fixed circular plate 601. The top of the rubber ring 602 fits with the bottom surface of the hollow circular plate 502. When the telescopic discharge tube 511 rotates, it can drive the fixed circular plate 601 to rotate synchronously, so that the rubber ring 602 always maintains a sealing effect on the bottom of the fixed circular plate 601, preventing a large amount of dust and impurities from entering the interior of the hollow circular plate 502 through the gap between the sealing circular plate 506 and the circular hole 503, affecting the transmission between the small gear 510 and the large gear 508.

[0031] In the present invention, when in use, the filling bag is placed on the outside of the placement rack 2, and the electric telescopic rod is started to drive the connecting cover 4 to move downward to press and fix the filling bag, then the electric push rod 501 is started to drive the hollow circular plate 502 to move downward to the bottom end of the filling bag, and then the filling machine 3 is started to fill the additive into the filling bag through the telescopic discharge pipe 511. During the filling process, the motor 509 can be started to drive the telescopic discharge pipe 511 to rotate, so that the additive can be evenly filled into the entire inner part of the filling bag. The hollow circular plate 502 is used to block the flying dust, thereby preventing the admixture from accumulating at the inner center of the filling bag, and during the filling process, the electric push rod 501 is started to drive the hollow circular plate 502 to move slowly upward, so that the bottom end of the telescopic discharge pipe 511 always maintains a short distance from the surface of the admixture, thereby preventing the telescopic discharge pipe 511 from being far away from the surface of the admixture, resulting in a large amount of dust during the filling process. The hollow circular plate 502 can block the flying dust, thereby preventing the dust inside the filling bag from flying to the outside and polluting the environment after the connection cover 4 is started and left immediately after the filling is completed.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
