Description

Technical Field

[0001] The invention belongs to the technical field of agitators, and in particular relates to an energy-saving long-axis permanent magnet synchronous motor connection mechanism for agitators. Background Art

[0002] The stirring system is widely used in various fields. It uses mechanical means to replace manual stirring to maximize the stirring efficiency. The stirring system has different output powers according to the stirring volume and working conditions.

[0003] However, the traditional mixing system has the disadvantages of large size, low transmission efficiency, easy oil leakage, and high maintenance. In particular, the larger the motor power or the larger the reducer, the higher the subsequent maintenance cost and the greater the maintenance workload. At the same time, the transmission efficiency is significantly reduced after the reducer and other components are matched. This leads to the high operating cost of the traditional mixing system, which is not suitable for the long-term development and use of the enterprise.

[0004] A Chinese patent application with publication number CN112371032A discloses a permanent magnet direct-drive energy-saving stirring system, in which the output shaft of the permanent magnet direct-drive motor and the stirring shaft are connected by a coupling. The setting of the coupling makes the connection between the output shaft and the stirring shaft simpler, without relying on traditional transmission mechanisms for transmission, avoiding friction losses caused by the operation of the transmission mechanism, and ensuring the strength required for transmission, thereby improving transmission efficiency and reducing costs.

[0005] However, this technical solution still has at least the following defects: when the coupling is used for connection, the agitator shaft may fall due to the loose connection of the coupling, which may cause danger. At the same time, when the agitator is working, the stirring material may splash onto the coupling. After the water evaporates, the residue may block the coupling, making it inconvenient to disassemble the coupling. In addition, the coupling is located close to the motor, making it inconvenient to clean it. In view of this, the present invention is proposed. Summary of the invention

[0027] like Figure 5 , Figure 6 As shown, further, a full-covering mosaic plate 108 is fixedly mounted on one end of the support plate 1141, and two symmetrically distributed mounting plates 1132 are arranged on one side of the full-covering mosaic plate 108. One end of each of the two mounting plates 1132 is rotatably connected to a guide plate 113, and a magnetic strip 1131 is fixedly mounted on one side of the guide plate 113. The magnetic strips 1131 on the two guide plates 113 attract each other. In this configuration, the guide plates 113 can maintain an adjustable opening and closing state through the magnetic strip 1131, which is convenient for operation.

[0028] like Figure 4-Figure 6 As shown, further, two guide grooves 131 are provided on the full-coverage mosaic plate 108, the paths of the guide grooves 131 are spiral, and the two guide grooves 131 are slidably connected with sliders 130, and one end of the slider 130 is fixedly mounted on one side of the mounting plate 1132. In this configuration, the mounting plate 1132 drives the slider 130 to rotate, and the slider 130 moves outward through the action of the guide grooves 131, and drives the mounting plate 1132 to move, and at this time, the mounting plate 1132 slides relative to the rotating plate 132.

[0029] Example 3

[0030] like Figure 3-Figure 6 As shown, in a specific embodiment, a rotating plate 132 is movably inserted on each of the two mounting plates 1132, a support ring 142 is fixedly installed between the two rotating plates 132, the support ring 142 is located outside the water spray ring 127, a fixed ring 1143 is fixedly installed on the full-coverage inlay plate 108, two movable blocks 140 are slidably connected to the fixed ring 1143, the two movable blocks 140 are respectively fixedly installed at one end of the two rotating plates 132, and a pull rod 141 is fixedly installed on one side of the movable block 140. In this setting, the pull rod 141 is rotated, and the pull rod 141 drives the two rotating plates 132 to rotate through the movable block 140, and the rotating plate 132 drives the mounting plate 1132 to rotate.

[0031] like Figure 3-Figure 5 As shown, further, a fixing frame 134 is fixedly installed on one side of the mounting plate 1132, and two limit blocks 135 are slidably connected inside the fixing frame 134. A blocking rod 136 is fixedly installed on one end of the limit block 135. An inclined sliding groove 133 is provided on the rotating plate 132, and the blocking rod 136 is slidably connected in the inclined sliding groove 133. A support frame 137 is fixedly installed on the other end of the limit block 135. A through groove 139 is provided on the guide plate 113, and pads 138 are fixedly installed on both sides of the through groove 139, and the pads 138 are adapted to the support frame 137. In this arrangement, the mounting plate 1132 slides relative to the rotating plate 132 and drives the fixing frame 134 to follow the movement. The fixing frame 134 drives the blocking rod 136 to move through the limit block 135. The two blocking rods 136 move toward each other under the action of the inclined slide groove 133 and drive the support frame 137 to move toward each other through the limit block 135 until the support frame 137 is offset from the pad 138. At this time, the support frame 137 is aligned with the through groove 139, thereby facilitating the opening of the guide plate 113.

[0032] like Fig.10As shown, further, a blade pressure plate 121 is provided at the end of the blade seat 120, and the blade pressure plate 121 is fixedly connected to the output long shaft 101 by bolts. The blade pressure plate 121 is adapted to the inner wall of the blade seat 120, and the diameter of the blade pressure plate 121 is larger than the diameter of the end of the output long shaft 101 close to the blade seat 120. A blade pressure cover 122 is fixedly installed at the end of the blade seat 120 away from the output long shaft 101 by bolts. The blade pressure cover 122, the blade seat 120 and the output long shaft 101 form a closed space, and the blade pressure plate 121 is located in the closed space. In this arrangement, when the blade 124 needs to be disassembled, the blade cover 122 is detached by unscrewing the bolts, and the blade pressure plate 121 is detached by loosening the bolts. At this time, the blade seat 120 can be separated from the output long shaft 101. During installation, it is only necessary to tighten the blade pressure plate 121 and the blade cover 122 with bolts. The enclosed space formed by the blade cover 122, the blade seat 120 and the output long shaft 101 can prevent the stirring liquid from entering the interior of the blade seat 120 and causing the residue after the water evaporates to block the blade seat 120.

[0033] like Figure 1 , Figure 2 , Fig.10 As shown, further, the blades 124 and the connecting disk 123 are both provided with a plurality of equal angles, and each connecting disk 123 is provided with an adjustment slot 125, and a plurality of bolts are installed on the blade seat 120, and the bolts are movable through the adjustment slot 125 and extend to the outside. In this setting, when the angle needs to be adjusted, the connecting disk 123 is loosened by loosening the bolts, and the angle of the blade 124 can be adjusted by rotating the connecting disk 123. When the angle is adjusted to a suitable angle, the bolts are tightened, and the bolts are pressed against the connecting disk 123 through the adjustment slot 125 to fix the blade 124.

[0034] The implementation principle of the energy-saving long-shaft permanent-magnet synchronous motor connection mechanism for a stirrer of this embodiment is as follows: when in use, the driving motor 100 directly drives the output long shaft 101 to rotate, and the output long shaft 101 directly drives the connecting plate 123 and the blade 124 to rotate through the blade seat 120, thereby realizing the stirring function. In this process, the stirrer does not need to have excessive transmission, avoiding the loss caused by the transmission mechanism, and improving the energy-saving efficiency of the stirrer; The liquid splashed out during the stirring process falls on the guide plate 113 to prevent the liquid from entering the stirrer part. At the same time, the inclined setting of the guide plate 113 allows the liquid to drip, and drives the shaft sleeve 112 to rotate during the rotation of the output long shaft 101. The shaft sleeve 112 increases the sealing performance with the packing machine sealing chamber 103 through the high water-based packing 111 and the sealing ring 110; When the use is finished, the water source is connected through the water inlet pipe 114, so that the water flows into the water spray ring 127 through the water inlet pipe 114 and the conduit 126, and the multi-angle cleaning of the guide plate 113 is realized through the water spray holes 128 on the water spray ring 127. At the same time, the water inlet pipe 114 can be used as a water replenishing device to replenish the mixing material; The guide plate 113 is manually cleaned by opening the guide plate 113, and the pull rod 141 is rotated. The pull rod 141 drives the two rotating plates 132 to rotate through the movable block 140, and the rotating plate 132 drives the mounting plate 1132 to rotate. The mounting plate 1132 drives the slider 130 to rotate, and the slider 130 moves outward through the action of the guide groove 131, and drives the mounting plate 1132 to move. At this time, the mounting plate 1132 slides relative to the rotating plate 132, and drives the fixing frame 134 to move. The fixing frame 134 drives the blocking rod 136 to move through the limit block 135. The two blocking rods 136 move toward each other under the action of the inclined slide groove 133, and drive the support frame 137 to move toward each other through the limit block 135 until the support frame 137 is staggered with the pad 138. At this time, the support frame 137 is aligned with the through groove 139, so as to facilitate the opening of the guide plate 113. When the angle needs to be adjusted, the connecting plate 123 is loosened by loosening the bolts. At this time, the angle of the blade 124 can be adjusted by rotating the connecting plate 123. When the angle is adjusted to a suitable angle, the bolts are tightened. The bolts press the connecting plate 123 through the adjustment slots 125 to fix the blade 124. When it is necessary to disassemble the blade 124, the blade cover 122 is detached by unscrewing the bolts, and the blade pressure plate 121 is detached by loosening the bolts. At this time, the blade seat 120 can be separated from the output long shaft 101. During installation, it is only necessary to tighten the blade pressure plate 121 and the blade cover 122 with bolts. The enclosed space formed by the blade cover 122, the blade seat 120 and the output long shaft 101 can prevent the stirring liquid from entering the interior of the blade seat 120 and causing the residue after the water evaporates to block the blade seat 120.
