Description

Technical Field

[0001] This utility model relates to the field of tank cleaning technology, and in particular to an automatic cleaning device for metering tanks. Background Technology

[0002] In the food industry, after being cut, materials are weighed in a metering tank and then filled into a storage tank. To facilitate filling and reduce intermediate piping, the storage tank is usually located directly below the metering tank. After a period of use, the metering tank needs to be sterilized and cleaned. Traditional cleaning methods typically involve a T-junction pipe located below the metering tank, connecting the storage tank and the metering tank. One T-junction serves as the material inlet, one as the material outlet, and one as the connection to the cleaning fluid line. Because of this T-junction, some pipes and valves are inevitably left uncleaned during cleaning. Therefore, there is a pressing need for an automatic metering tank cleaning device that eliminates the T-junction on the filling pipeline between the metering tank and the storage tank, reduces unsanitary areas, separates the cleaning and filling pipelines, automates cleaning, reduces workload, and improves production efficiency.

The storage tank 2 is located below the metering tank 1; the metering tank 1 is used for weighing, and the storage tank 2 is used for storing materials.

[0036] The cleaning fluid feeding assembly further includes a first valve 9 and a second valve 10.

The filling pipeline 3 connects the storage tank 2 and the metering tank 1, and a third valve 11 is installed on the filling pipeline 3. The third valve 11 is used to control automatic filling.

[0037] The cleaning fluid discharge assembly further includes a clamping block 12, which is disposed between the first row of cleaning fluid pipelines 6 and the cylinder 8. In this embodiment, the clamping block 12 connects the first row of cleaning fluid pipelines 6 and the cylinder 8. The cleaning fluid discharge assembly also includes a rotary joint 13, which is disposed between the first row of cleaning fluid pipelines 6 and the second row of cleaning fluid pipelines 7.

[0038] The cylinder 8 has a piston rod 14 at its output end, a first rotating shaft 15 between the piston rod 14 and the clamping block 12, and a second rotating shaft 16 at its tail end. A third rotating shaft 17 is provided on the rotary joint 13. The rotary joint 13 is hollow, with ports at both ends, and these ports can rotate 360° around the third rotating shaft 17. In this embodiment, one end of the piston rod 14 has a double elbow joint 18, and the first rotating shaft 15 connects the double elbow joint 18 to the clamping block 12. The double elbow joint 18 is Y-shaped, and both the double elbow joint 18 and the clamping block 12 can rotate around the first rotating shaft 15.

The rotary joint 13 can rotate 360 ​​degrees. The cylinder 8 can drive the first row of cleaning fluid pipes 6 to rotate. The cylinder 8 can rotate around the second rotating shaft 16. The piston rod 14 of the cylinder 8 is connected to the first row of cleaning fluid pipes 6 through the clamping block 12. The double elbow joint 18 and the clamping block 12 can rotate around the first rotating shaft 15. After the piston rod 14 of the cylinder 8 extends, it drives the rotary joint 13, the second rotating shaft 16 at the tail end of the cylinder, and the first rotating shaft 15 to rotate at three positions. The rotation at the rotary joint 13 can align the inlet axis of the first row of cleaning fluid pipes 6 with the outlet axis of the metering tank 1.

[0040] The automatic cleaning device for the metering tank also includes a metering tank support 21, which is disposed at the bottom of the metering tank 1. The automatic cleaning device also includes a PLC control system, which is electrically connected to the first valve 9 and the cylinder 8. In this embodiment, a first solenoid valve is provided between the PLC control system and the first valve 9, and the first solenoid valve is used to control the movement of the first valve 9. A second solenoid valve is provided between the PLC control system and the cylinder 8, and the second solenoid valve is used to control the movement of the cylinder 8.

[0041] When using the automatic cleaning device for the metering tank, firstly, the third valve 11 is opened to transport the material in the metering tank 1 to the storage tank 2 through the filling pipeline 3. When the metering tank 1 needs cleaning, the PLC control system sends a signal to the first solenoid valve that controls the movement of the first valve 9, which opens the first valve 9. The cleaning fluid flows from the cleaning fluid inlet pipeline 4 through the rotating spray head 5 to clean the inner wall of the metering tank 1. When discharging the cleaning fluid, the PLC control system sends a signal to the second solenoid valve that controls the movement of the cylinder 8, which extends the piston rod 14 of the cylinder 8, causing the first row of cleaning fluid pipelines 6 to rotate around the rotary joint 13, thus automatically connecting the first row of cleaning fluid pipelines 6 with the discharge port at the bottom of the metering tank 1.

[0042] In this embodiment, the automatic cleaning device for the metering tank also includes a loading machine. The second row of cleaning fluid pipelines 7 and the cylinder mounting base 19 are respectively fixed on the loading machine. The second row of cleaning fluid pipelines 7 is fixed on the loading machine by pipe clamps, and the cylinder mounting base 19 is fixed on the loading machine by a first screw. One end of the piston rod 14 of the cylinder 8 is provided with a Y-shaped double elbow joint 18, and the tail end of the cylinder 8 is mounted with a swing foot 20 by a second screw. The second rotating shaft 16 is connected to the swing foot 20 and the cylinder mounting base 19, and the cylinder 8 can rotate around the second rotating shaft 16. The first rotating shaft 15 is connected to the double elbow joint 18 and the clamping block 12, and the double elbow joint 18 and the clamping block 12 can rotate around the first rotating shaft 15. The first row of cleaning fluid pipelines 6 and the clamping block 12 are locked and fixed by a third screw. A bend is provided between the first row of cleaning fluid pipelines 6 and the rotary joint 13. One end of the bend is fixedly connected to the first row of cleaning fluid pipelines 6 (specifically, by welding), and the other end of the bend is fixedly connected to the rotary joint 13 (specifically, by welding). The horizontal axis of the first row of cleaning fluid pipelines 6 is converted into the direction perpendicular to the horizontal plane of the second row of cleaning fluid pipelines 7 through the bend. The rotary joint 13 has a hollow structure with ports at both ends, one for feeding and the other for discharging. The ports at both ends can rotate 360° around the third rotating shaft. When the cylinder 8 is started, compressed air is introduced into the air inlet of the cylinder 8, and the piston rod 14 extends. The positions of the first rotating shaft 15, the second rotating shaft 16, and the third rotating shaft 17 rotate, aligning the inlet axis of the top of the first row of cleaning fluid pipelines 6 with the outlet axis of the metering tank 1, thereby conveying the cleaning fluid. After the cleaning fluid is delivered, the piston rod 14 of the cylinder 8 retracts, and the positions of the first rotating shaft 12, the second rotating shaft 16 and the third rotating shaft 17 rotate in opposite directions, thereby driving the first row of cleaning fluid pipelines 6 to move, providing sufficient receiving space for the storage tank 2.

[0043] In summary, the automatic cleaning device for metering tanks provided by this utility model designs the cleaning fluid discharge pipeline as an independent pipeline and uses a PLC control system for automatic control, achieving automatic docking during use. When the storage tank needs to receive material, the first discharge cleaning fluid pipeline can be rotated and folded to avoid obstruction. This structure eliminates sanitary dead corners in integrated pipelines, achieving comprehensive automatic cleaning.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
