Description

Technical Field

[0001] The invention relates to the technical field of beer production, in particular to an automatically switched deoxygenated water pipeline CIP cleaning device. Background Art

[0002] Before the traditional deoxygenated water pipeline CIP cleaning device was modified, the four-way valve was installed at the location of two flexible cross-tubes. Each time deoxygenated water or deoxygenated water pipeline was CIP cleaned, the cross-tubes needed to be removed.

The residual oxygen in the cross-tubes would be incorporated into the deoxygenated water during the subsequent production of deoxygenated water, affecting the quality of the beer.

[0027] The disclosed automatic switching deoxygenated water pipeline CIP cleaning device operates as follows: The deoxygenated water CIP cleaning jumper panel modification is designed to reduce labor and facilitate operation, minimizing contact between residual oxygen and deoxygenated water caused by the removal of jumper pipes (vertical jumper pipe 3 and horizontal jumper pipe 4) during operation. Prior to the modification, two flexible jumper pipes were installed where the four-way valves were installed. Each time deoxygenated water or deoxygenated water pipelines were CIP cleaned, the jumper pipes had to be removed. During the installation and removal process, air trapped within the jumper pipes could not be removed, allowing residual oxygen to be incorporated into the deoxygenated water during subsequent production, impacting beer quality. By installing a four-way valve between the jumper pipes, the jumper pipes no longer need to be removed, allowing for flexible switching between the deoxygenated water pipeline and the CIP pipeline, eliminating dissolved oxygen in the deoxygenated water.

[0028] Specifically, it can be done by controlling the rotation direction and rotation speed of the drive motor 108. When the drive motor 108 is started at a low speed, the drive motor 108 rotates forward (specifically depending on the rotation direction of the thread setting on the drive screw 125) to drive the drive screw 125 to rotate (the drive screw 125 is driven to rotate by the spline shaft 114, the spline cylinder 117, the power input transfer plate 118, and the power output transfer plate 119). The rotation of the drive screw 125 will drive the intermediate transfer plate 122 to move axially through the nut friction block 124 (due to the permanent magnet column 123 provided in the intermediate transfer plate 122, the permanent magnet column 123 will be subject to the magnetic constraint of the permanent magnet ring 111, thereby limiting the rotation of the intermediate transfer plate 122), the intermediate transfer plate 122 will contact the upper ball valve transfer plate 126, and then the intermediate transfer plate 122 and The upper ball valve transfer plate 126 is engaged. Since the intermediate transfer plate 122 cannot rotate, the upper ball valve transfer plate 126 cannot rotate either. At this time, the driving screw 125 can no longer drive the nut friction block 124 to move downward, so it will drive the nut friction block 124 and the intermediate transfer plate 122 to rotate relative to each other. When the driving screw 125 rotates, the center gear 129 rotates. The rotation of the center gear 129 will drive the outer ring gear 131 to rotate through the planetary gears 128 (the upper ball valve transfer plate 126 and the planetary carrier 130 are restricted by the intermediate transfer plate 122 and cannot rotate). The rotation of the outer ring gear 131 will drive the transmission sleeve 133 to rotate. The rotation of the transmission sleeve 133 will drive the upper T-shaped channel ball valve 105 to rotate, and the channel in the upper T-shaped channel ball valve 105 will be rotated to the desired position.

[0029] When the drive motor 108 reverses, the intermediate transfer disc 122 moves upward, and the intermediate transfer disc 122 will engage with the lower ball valve transfer disc 120, limiting the rotation of the lower ball valve transfer disc 120. The inability of the lower ball valve transfer disc 120 to rotate will cause the lower ball valve transfer seat 121 to be unable to rotate, and the inability of the lower ball valve transfer seat 121 to rotate will cause the outer ring gear 131 to be unable to rotate. At this time, the rotation of the center gear 129 will drive the planetary carrier 130 to rotate (the planetary gear 128 revolves), and the rotation of the planetary carrier 130 will drive the center shaft 135 to rotate. The rotation of the center shaft 135 will drive the lower T-shaped channel ball valve 104 to rotate, and the channel in the lower T-shaped channel ball valve 104 will be rotated to the described position.

[0030] When the rotation speed of the drive motor 108 is increased, the rotation speed of the spline shaft 114 will increase, and the lead ball 116 will also rotate. The lead ball 116 will move outward under the action of centrifugal force, and then the spline cylinder 117 and the power input transfer plate 118 will be pulled up by the arc-shaped elastic rod 115. At this time, the power input transfer plate 118 will be disengaged from the power output transfer plate 119. At this time, the rotation of the power input transfer plate 118 cannot drive the power output transfer plate 119 to rotate, and thus cannot drive the drive screw 125 to rotate. At the same time, the power input transfer plate 118 will engage with the blocking plate transfer plate 113. At this time, the blocking plate transfer plate 113 rotates, and the blocking plate transfer plate 119 is disengaged. The rotation of the blocking plate transfer seat 127 will drive the rotation of the blocking plate transfer seat 127, which will drive the outer ring permanent magnet 132 of the blocking plate to rotate, which will drive the inner permanent magnet 134 of the blocking plate to rotate, which will drive the rotating shaft sleeve 136 to rotate, which will drive the upper blocking plate 106 and the lower blocking plate 107 to move away from or closer to each other (depending on the rotation direction of the drive motor 108). When the upper blocking plate 106 and the lower blocking plate 107 move away from each other, the communication chamber 103 is in an open state, and when the upper blocking plate 106 and the lower blocking plate 107 move closer to each other, the communication chamber 103 is in a closed state.

[0031] By controlling the position of the lower T-shaped channel ball valve 104, the upper T-shaped channel ball valve 105, the upper blocking plate 106 and the lower blocking plate 107, the pipeline where the liquid flows can be controlled, such as Figure 9 As shown, liquid can flow in from the left side of the top ball valve chamber 102 and out from the right side of the top ball valve chamber 102 (the communicating chamber 103 is closed). At the same time, liquid can flow in from the front side of the bottom ball valve chamber 101 and out from the back side of the bottom ball valve chamber 101. Liquid can also flow in from the left side of the top ball valve chamber 102, pass through the communicating chamber 103, and out from the front or north side of the bottom ball valve chamber 101. Similarly, if liquid flows in from the right side of the top ball valve chamber 102, the front side of the bottom ball valve chamber 101, or the north side of the bottom ball valve chamber 101, the same effect will be achieved.
