Description

Technical Field

[0001] This utility model relates to the field of tail gas treatment liquid production, and in particular to a tail gas treatment liquid production filling conveyor. Background Technology

[0002] Exhaust gas treatment fluid is the core reducing agent of SCR technology, used to reduce nitrogen oxide emissions in diesel vehicle exhaust. Its production and filling process must ensure high purity and no impurities to avoid clogging the delivery system or affecting catalytic efficiency. In existing technologies, filling equipment typically includes basic structures such as storage tanks, conveyor belts, and filling nozzles.

[0003] Chinese utility model patent discloses a high-purity tail gas treatment liquid quantitative filling device (application number: 202421117499X). This application draws the treatment liquid from the storage tank into the packaging tank by opening the filling mechanism to carry out quantitative filling; it achieves the goal of facilitating automatic adjustment of the filling height of the filling device.

[0004] Although the above application achieved precise quantitative filling through dynamic adjustment of the filling mechanism, there are still technical defects in the process connection. The filling unit and the capping process adopt a physical separation design. The semi-finished product after filling needs to be transferred to the work station via an open conveyor belt. During the transfer process, the container shakes and liquid overflows easily. In addition, the volatile components (mainly ammonia substances) in the tail gas treatment liquid are prone to escape during the transfer stage, which seriously affects the reliability of the device operation.

[0005] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0030] The working process and principle of this utility model are as follows:

[0031] In use, the square bucket 14 is first conveyed to the top of the conveyor belt 12 by the conveying mechanism. At this time, the distance between the limit plates 13 is adjusted so that the square bucket 14 is conveyed in the center. At the same time, the vibrating feeder 16 is started. The vibrating feeder 16 conveys the bucket lid 15 to one end of the feeding rack 17. After the square bucket 14 is conveyed to the bottom of the gantry 21, the stepper motor 11 is turned off and the lead screw motor 25 is started. When the lead screw motor 25 is started, it drives the lead screw nut 28 to move towards the side closer to the vibrating feeder 16 until the clamp 39 reaches the top of the bucket lid 15 and the filling head 33 reaches the top of the filling port of the square bucket 14.

[0032] At this time, the electric push rod 30 is activated, which drives the mounting plate 32 to move downward, so that the filling head 33 contacts the filling port of the square barrel 14. At the same time, the clamp 39 is fitted on the outside of the barrel cover 15, and the barrel cover 15 is limited by friction. Then, the metering pump 23 is activated, and the metering pump 23 fills the exhaust gas treatment liquid in the storage tank 24 into the square barrel 14. After filling is completed, the electric push rod 30 is activated to drive the mounting plate 32 to rise, and the screw motor 25 is activated to drive the clamp 39 to move above the filling port of the square barrel 14. Then, the electric push rod 30 is activated to drive the mounting plate 32 and the clamp 39 to press down until the filling port of the square barrel 14 contacts the barrel cover 15. At this time, the stepper motor 34 is activated, and the stepper motor 34 drives the spur gear 37 to rotate through the spur gear 35. The spur gear 37 drives the clamp 39 to rotate through the spline shaft 36, thereby completing the integrated filling and capping operation of the exhaust gas treatment liquid.
