[0002] In the field of reaction vessel technology, stirred tanks are widely used mixing reaction equipment in industries such as chemical, pharmaceutical, and food processing. Their feeding efficiency and stirring effect directly affect the continuity of the production process and product quality. Traditional stirred tanks often require shutdown during the feeding process, which greatly reduces production efficiency. Furthermore, existing stirring structures have poor adaptability to material properties and stirring stages, making it difficult to flexibly adjust the stirring intensity and range. This easily leads to stirring dead zones and adhesion to the inner wall, resulting in difficult cleaning, high maintenance costs, and potential cross-contamination. Consequently, they cannot meet the urgent needs of modern production for high efficiency, high uniformity, and automated control. Therefore, this application provides a stirred tank with rapid feeding capability. Summary of the Invention

Detailed Implementation
[0033] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0034] like Figures 1 to 15 As shown in the figure, the rapidly feeding mixing vessel described in this embodiment mainly includes a support base 101. A first annular shell 102 and a second annular shell 106 are disposed on the support base 101. The first annular shell 102 is located directly below the second annular shell 106. An annular rotating frame 107 is movably disposed between the first annular shell 102 and the second annular shell 106. Both the first annular shell 102 and the second annular shell 106 are fixedly mounted on the support base 101. The annular rotating frame 107 is rotatably connected to the upper end face of the first annular shell 102 and the lower end face of the second annular shell 106. Next, the inner walls of the first annular shell 102, the second annular shell 106, and the annular rotating frame 107 are on the same circumferential surface. A circular base plate 103 is slidably installed on the lower end face of the first annular shell 102. A separation screw 104 is provided between the first annular shell 102 and the circular base plate 103. The separation screw 104 is rotatably installed on the outer wall of the first annular shell 102. A separation motor 105 is also fixedly installed on the outer wall of the first annular shell 102. The output shaft of the separation motor 105 is fixedly connected to the separation screw 104. The separation screw 104 and the circular base plate 103 form a helical pair.
[0035] A stirring assembly is provided on the second annular shell 106. The stirring assembly includes a circular rotating plate 120 rotatably mounted on the second annular shell 106. A shifting circular plate 121 is symmetrically rotatably mounted on the circular rotating plate 120. A strip-shaped stirring plate 114 is fixedly mounted at the eccentric position of the shifting circular plate 121. When the strip-shaped stirring plate 114 is at the position farthest from the axis of the linkage gear ring 133, the surface of the strip-shaped stirring plate 114 farthest from the axis of the linkage gear ring 133 is on the same circumferential surface as the inner wall of the second annular shell 106. When the circular bottom plate 103 is located directly below the first annular shell 102, a sealed stirring cylinder is formed between the first annular shell 102, the circular bottom plate 103, the second annular shell 106, the annular rotating frame 107, and the circular rotating plate 120. Starting the separation motor 105 drives the separation screw 104 to rotate, which causes the circular bottom plate 103 to slide relative to the first annular shell 102, thereby controlling the opening and closing of the lower end face of the stirring cylinder.
[0036] A feeding assembly is provided on the second annular shell 106. The feeding assembly includes a storage cone 108 and a feed pipe 109, as well as an opening and closing unit located between the storage cone 108 and the feed pipe 109. The storage cone 108 and the feed pipe 109 are both fixedly mounted on the support base 101. The opening and closing unit includes a switching circular plate 112. Circular sealing plates 111 are fixedly mounted on the lower end face of the storage cone 108 and the upper end face of the feed pipe 109. The circular sealing plates 111 and the switching circular plate 112 have the same size. The switching circular plate 112 is located between the two circular sealing plates 111. The switching circular plate 112 is... Two circular sealing plates 111 are rotatably connected. The eccentric positions of the circular sealing plates 111 and the switching circular plate 112 are provided with through holes with the same inner diameter as the feed pipe 109. The through holes on the two circular sealing plates 111 are respectively connected to the storage cone 108 and the feed pipe 109. The distance from the through hole on the circular sealing plate 111 to the axis of the circular sealing plate 111 is equal to the distance from the through hole on the switching circular plate 112 to the axis of the switching circular plate 112. An opening and closing motor 110 is fixedly installed on the circular sealing plate 111 on the storage cone 108. The output shaft of the opening and closing motor 110 is fixedly connected to the switching circular plate 112.
[0037] Both the transposition circular plates 121 are provided with arc-shaped notches, and the circular rotating plate 120 is provided with through holes of the same inner diameter as the feed pipe 109. When the arc-shaped notches on the two transposition circular plates 121 are located at the closest position, the arc-shaped surfaces of the arc-shaped notches on the two transposition circular plates 121 and the through holes on the circular rotating plate 120 are on the same circumferential surface.
[0038] When it is necessary to add material into the mixing cylinder, first make the arc-shaped notches on the two switching discs 121 be in the closest position, and then start the opening and closing motor 110 to drive the switching disc 112 to rotate, so that the position of the through hole on the switching disc 112 can be adjusted. When the through hole on the switching disc 112 and the through hole on the circular sealing plate 111 are connected, the storage cone 108 and the feed pipe 109 can be connected, thereby connecting the storage cone 108 and the inside of the mixing cylinder. The cylinder to be added in the storage cone 108 enters the inside of the mixing cylinder along the feed pipe 109. The arc-shaped notch on the switching disc 121 is used to make way for the material during addition, thereby ensuring the flow of material addition and ensuring that the strip agitator 114 on the switching disc 121 can move to the center position of the mixing cylinder, that is, ensuring the maximum displacement of the strip agitator 114 on the switching disc 121.
[0039] The lower end face of the strip-shaped stirring plate 114 and the upper end face of the circular base plate 103 are on the same plane. A linkage unit is provided between the two shifting circular plates 121. The linkage unit includes a circular cover plate 132 fixedly installed on the circular rotating plate 120. The circular cover plate 132 is used to cover the shifting circular plates 121, that is, to ensure that the internal and external environments of the stirring cylinder are not connected due to the arc notch on the shifting circular plates 121 during rotation. The shifting circular plates 121 are all rotatably connected to the circular cover plate 132. A linkage gear ring 133 is rotatably installed on the circular cover plate 132. A linkage gear 134 is fixedly installed on each shifting circular plate 121. The linkage gear 134 meshes with the linkage gear ring 133 to form a gear pair. A linkage motor 135 is fixedly installed on the circular cover plate 132. The output shaft of the linkage motor 135 is fixedly connected to the corresponding linkage gear 134.
[0040] In the initial position, the arc-shaped notches on the two interchangeable circular plates 121 are at their closest positions, and the two strip-shaped stirring plates 114 are at their farthest positions. The surface of the strip-shaped stirring plate 114 furthest from the axis of the second annular shell 106 is in contact with the inner wall of the second annular shell 106. At this time, the driving circular rotating plate 120 rotates relative to the second annular shell 106, and the components on the circular rotating plate 120 rotate synchronously, so that the two strip-shaped stirring plates 114 rotate synchronously. During the rotation, the strip-shaped stirring plates 114 scrape off the inner wall of the stirring cylinder, thereby preventing the raw materials from always adhering to the inner wall of the stirring cylinder without reacting.
[0041] The linkage motor 135 is started to drive the corresponding linkage gear 134 to rotate. Under the action of the linkage gear ring 133, the two linkage gears 134 rotate synchronously, that is, the two shifting circular plates 121 rotate synchronously, and the strip stirring plates 114 on the shifting circular plates 121 rotate synchronously. This adjusts the distance between the strip stirring plates 114 and the axis of the second annular shell 106, thereby changing the position of the strip stirring plates 114 in the mixing cylinder, thereby improving the stirring effect of the strip stirring plates 114, and enabling the lower end face of the strip stirring plates 114 to scrape off the adhering substances on the upper surface of the circular bottom plate 103, thereby improving the mixing effect of the raw materials in the mixing cylinder. When the two strip stirring plates 114 are in the closest position, they come into contact, but this does not affect the continued movement of the strip stirring plates 114.
[0042] A lifting assembly is provided on the annular rotating frame 107. The lifting assembly includes two semi-circular rotating seats 116 rotatably mounted on the annular rotating frame 107. The two semi-circular rotating seats 116 are arranged in a circumferential array relative to the annular rotating frame 107. Two semi-circular bottom plates 117 are also fixedly provided on the annular rotating frame 107. The semi-circular rotating seats 116 are respectively located inside the corresponding semi-circular bottom plates 117. The semi-circular bottom plates 117 are used to cover and protect the semi-circular rotating seats 116. That is, the semi-circular bottom plates 117 block the gap between the semi-circular rotating seats 116 and the annular rotating frame 107 when the semi-circular rotating seats 116 rotate relative to the annular rotating frame 107, thereby preventing leakage of the stirring cylinder when the semi-circular rotating seats 116 rotate relative to the annular rotating frame 107.
[0043] A transmission unit is provided between the two semicircular rotating seats 116. The transmission unit includes two sector racks 130 and two transmission gears 131. The sector racks 130 are respectively fixedly installed on the corresponding semicircular rotating seats 116. The axis of the sector racks 130 is on the same straight line as the center line of the rotational connection between the corresponding semicircular rotating seat 116 and the annular rotating frame 107. The transmission gears 131 are rotatably installed on the annular rotating frame 107. The transmission gears 131 and the corresponding sector racks 130 mesh to form a gear rack pair. A second transmission group 128 is provided between the two transmission gears 131. The second transmission group 128 includes a belt and two pulleys. The two pulleys in the second transmission group 128 are respectively fixedly installed on the corresponding transmission gears 131. The belt in the second transmission group 128 is located between the two pulleys in the second transmission group 128. An angle adjustment motor 129 is also fixedly installed on the annular rotating frame 107. The output shaft of the angle adjustment motor 129 is fixedly connected to the corresponding pulley.
[0044] The start-up angle adjustment motor 129 drives the corresponding pulley to rotate. Under the action of the second transmission group 128, the two transmission gears 131 rotate synchronously. Under the action of the sector rack 130, the two semi-circular rotating seats 116 rotate synchronously, and the two semi-circular rotating seats 116 rotate in opposite directions.
[0045] Each semicircular rotating base 116 is slidably mounted with a strip-shaped lifting plate 113. The two strip-shaped lifting plates 113 are staggered, meaning they do not contact each other. When the end face of the strip-shaped lifting plate 113 located inside the annular rotating frame 107 moves to its furthest position from the axis of the annular rotating frame 107, this end face of the strip-shaped lifting plate 113 and the inner wall of the annular rotating frame 107 are on the same circumferential surface. An adjustment unit is provided between the two strip-shaped lifting plates 113. The adjustment unit includes two adjustment racks 124 and two adjustment gears 126. A linkage plate 115 is fixedly installed at the end furthest from the axis of the annular rotating frame 107. An adjusting rack 124 is fixedly installed on the corresponding linkage plate 115. An adjusting gear 126 is rotatably installed on the corresponding semi-circular rotating seat 116. The adjusting rack 124 and the corresponding adjusting gear 126 mesh to form a gear rack pair, driving the adjusting gear 126 to rotate. Under the action of the linkage plate 115 and the adjusting rack 124, the strip lifting plate 113 can slide relative to the semi-circular rotating seat 116, that is, adjust the position of the strip lifting plate 113 inside the stirring cylinder.
[0046] A support frame 118 is fixedly installed on the outer side of the annular rotating frame 107. An arc-shaped strip 127 is symmetrically rotatably mounted on the support frame 118. A fan-shaped long strip 125 is also symmetrically fixedly mounted on the support frame 118. When both ends of the arc-shaped strip 127 engage with the fan-shaped long strip 125, a complete annular plate is formed between them. Adjusting blocks 143 are fixedly mounted on the adjusting gears 126. The adjusting blocks 143 are provided with arc-shaped grooves that mate with the arc-shaped strip 127. The arc-shaped strip 127 and the support frame 118 are rotatably connected at... The center line is on the same straight line as the axis of the corresponding sector rack 130. A first transmission group 123 is provided between the two arc-shaped strips 127. The first transmission group 123 includes a belt and two pulleys. The two pulleys in the first transmission group 123 are respectively fixedly installed on the corresponding arc-shaped strips 127. The belt in the first transmission group 123 is located between the two pulleys in the first transmission group 123. An adjustment motor 119 is also fixedly installed on the support frame 118. The output shaft of the adjustment motor 119 is fixedly connected to the corresponding pulley.
[0047] In the initial position, the strip lifting plate 113 is located at the position furthest from the axis of the annular rotating frame 107. At this time, the end face of the strip lifting plate 113 closest to the axis of the annular rotating frame 107 and the inner wall of the annular rotating frame 107 are on the same circumferential surface, and the strip lifting plate 113 is in a horizontal state. That is, at this time, the arc-shaped strip plate 127 and the arc-shaped groove on the corresponding adjusting block 143 are in an engaged state. At this time, the circular rotating plate 120 is driven to rotate, so that the strip stirring plate 114 scrapes and cleans the inner wall of the stirring cylinder, that is, the inner wall of the annular rotating frame 107 is cleaned. At this time, the strip lifting plate 113 will not affect the movement of the strip stirring plate 114.
[0048] When the adjusting motor 119 is started, under the action of the first transmission group 123, the two arc-shaped strips 127 rotate synchronously. The arc-shaped strips 127 rotate relative to the fan-shaped long strip 125, causing the two adjusting blocks 143 to rotate synchronously. This, in turn, causes the two adjusting gears 126 to rotate synchronously. Under the action of the adjusting gears 126, the two adjusting racks 124 move towards each other. Under the action of the linkage strip 115, the two strip-shaped lifting plates 113 move towards each other, ultimately causing the end face of the strip-shaped lifting plate 113 to contact the other side of the inner wall of the annular rotating frame 107. When the two ends of the arc-shaped strip 127 rejoin the corresponding fan-shaped strip 125 to form a complete ring plate, the angle adjustment motor 129 is started to drive the two semi-circular rotating seats 116 to rotate. The components on the semi-circular rotating seats 116 rotate synchronously, and the adjusting block 143 rotates relative to the corresponding arc-shaped strip 127. This ensures that the arc-shaped groove on the adjusting block 143 engages with the fan-shaped strip 125. Under the action of the fan-shaped strip 125, the adjusting block 143 will not rotate. That is, under the action of the fan-shaped strip 125, the position of the adjusting block 143 is prevented from changing during the movement.
[0049] Under the action of the semi-circular rotating seat 116, the strip lifting plate 113 rotates up and down inside the mixing cylinder, thereby lifting and mixing the raw materials inside the mixing cylinder. This allows the raw materials at the bottom of the mixing cylinder to move upward under the action of the strip lifting plate 113, thereby improving the mixing effect of the raw materials inside the mixing cylinder.
[0050] A drive unit is also provided between the circular rotating plate 120 and the annular rotating frame 107. The drive unit includes a drive ratchet ring 122, a driven gear ring 139, a driven gear 140, a drive ratchet wheel 141, and a third transmission group 142. The drive ratchet ring 122 is fixedly mounted on the circular rotating plate 120, and the driven gear ring 139 is fixedly mounted on the support frame 118. The driven gear 140 and the drive ratchet wheel 141 are both rotatably mounted on the outer wall of the second annular housing 106. The drive ratchet wheel 141 and the drive ratchet ring 122 engage to form a ratchet mechanism, and the driven gear 140 and the driven gear ring 139 mesh to form a gear pair. The third transmission group 141... 2. The third transmission group 142 is located between the driven gear 140 and the ratchet 141. The third transmission group 142 includes a belt and two pulleys. The two pulleys in the third transmission group 142 are respectively fixedly installed on the driven gear 140 and the ratchet 141. The belt in the third transmission group 142 is located between the two pulleys in the third transmission group 142. The drive motor 136 is also fixedly installed on the support base 101. The drive gear 137 is fixedly installed on the output shaft of the drive motor 136. The drive gear ring 138 is fixedly installed on the circular cover plate 132. The drive gear 137 and the drive gear ring 138 mesh to form a gear pair.
[0051] When the strip agitator 114 scrapes off the deposits on the inner wall of the annular rotating frame 107, the strip lifting plate 113 is first moved to the position furthest from the axis of the annular rotating frame 107. Then, the drive motor 136 is started to drive the drive gear 137 to rotate. Under the action of the drive gear ring 138, the circular cover plate 132 rotates, which causes the circular rotating plate 120 to rotate. At this time, the drive ratchet ring 122 rotates relative to the drive ratchet wheel 141. That is, the annular rotating frame 107 will not rotate at this time. Thus, under the action of the strip agitator 114, the deposits on the inner wall of the annular rotating frame 107 are scraped off.
[0052] When the strip-shaped lifting plate 113 and the strip-shaped stirring plate 114 simultaneously stir the raw materials inside the stirring cylinder, the drive motor 136 is first started to make the circular rotating plate 120 rotate relative to the annular rotating frame 107. That is, the position of the strip-shaped stirring plate 114 is first adjusted so that the two strip-shaped stirring plates 114 and the two strip-shaped lifting plates 113 are arranged in a circular array relative to the axis of the circular rotating plate 120. At this time, the strip-shaped lifting plates 113 and the strip-shaped stirring plates 114 are spaced apart. Then, the drive motor 136 is started to drive the drive gear 137 to rotate in the opposite direction. Under the action of the drive ratchet ring 122, the drive ratchet 141 rotates. Under the action of the third transmission group 142, the driven gear... When 140 rotates, the annular rotating frame 107 rotates relative to the first annular housing 102 and the second annular housing 106 under the action of the driven gear ring 139. Under the action of the transmission ratio between the drive ratchet ring 122, the driven gear ring 139, the driven gear 140, the drive ratchet wheel 141, and the third transmission group 142, the angular velocities of the drive ratchet ring 122 and the driven gear ring 139 are the same, that is, the angular velocities of the circular rotating plate 120 and the annular rotating frame 107 are the same. This causes the strip agitator plate 114 and the strip lifting plate 113 to rotate synchronously. During the rotation, the position of the strip agitator plate 114 is adjusted so that it does not come into contact with the strip lifting plate 113.
[0053] Working principle: The cylinder to be stirred is added into the storage cone 108. After the raw material to be stirred in the first annular shell 102 is discharged from the circular bottom plate 103, the linkage motor 135 is started, so that the arc-shaped notches on the two shifting circular plates 121 are in the closest position. Then, through the opening and closing unit, the storage cone 108 and the stirring cylinder are connected. The raw material in the storage cone 108 enters the stirring cylinder along the feed pipe 109. After the addition is completed, the feed pipe 109 is closed through the opening and closing unit.
[0054] Then, the drive motor 136 is started. Under the action of the drive unit, the circular rotating plate 120 and the annular rotating frame 107 rotate synchronously. The linkage motor 135 is started. Under the action of the linkage unit, the distance between the axis of the strip stirring plate 114 and the circular rotating plate 120 is changed, that is, the position of the strip stirring plate 114 in the stirring cylinder is changed. At the same time, the angle adjustment motor 129 is started. Under the action of the transmission unit, both semi-circular rotating seats 116 rotate relative to the first annular shell 102, so that the strip lifting plate 113 rotates up and down inside the stirring cylinder, thereby realizing the lifting and mixing of the raw materials inside the stirring cylinder.
[0055] When it is necessary to clean the inside of the annular rotating frame 107, the annular rotating frame 107 is first driven to rotate by the drive motor 136, so that both strip lifting plates 113 are facing the open position of the support base 101, which facilitates the unfolding of the strip lifting plates 113. Then, the angle adjustment motor 129 is started to make the strip lifting plates 113 horizontal. Then, the adjustment unit moves the two strip lifting plates 113 to the farthest position. At this time, the inner wall of the annular rotating frame 107 can be cleaned by the strip stirring plate 114.
