DETAILED DESCRIPTION

[0020] like Figure 1-Figure 5 As shown, a solvent recovery device and recovery method include a furnace body 1 and a cover plate 101 arranged above the furnace body 1, a base 2 for heating the furnace body 1 is arranged below the furnace body 1, and in actual use, the furnace body 1 can be heated by direct fire heating or water bath heating, and a feed pipe and an exhaust pipe are fixedly installed on the furnace wall of the furnace body 1. Specifically, during the heating process, the solvent components in the furnace body 1 can evaporate and be discharged through the exhaust pipe, and can be liquefied when passing through the condenser, thereby completing the recovery and utilization of the solvent components in the original solution.

[0021] During actual use, as the solvent component evaporates, solid components will precipitate from the stock solution, and the solid components will accumulate at the bottom end of the furnace body 1. During the distillation process, as the stock solution is introduced into the furnace body 1 through the feed pipe, the stock solution will impact the solid components during its falling process, which may cause uneven distribution. In order to solve this problem, the present solution has a limit shaft 10 fixedly provided on the bottom end face of the cover plate 101, and an annular plate 8 is sleeved at a position close to the bottom end of the outer side of the limit shaft 10, and a collar 7 is rotatably sleeved on the outer side of the annular plate 8, and a lever 6 is fixedly installed on the outer side of the collar 7. Here, the collar 7 can only rotate relative to the annular plate 8 and cannot move in the vertical direction relative to the annular plate 8. Specifically, the annular plate 8 cooperates with the collar 7 through a plug-in assembly. Furthermore, a spiral limiting groove 1001 is provided on the outer circumferential surface of the limiting shaft 10. When the annular plate 8 rotates relative to the sleeve ring 7, the plug-in assembly is staggered with the sleeve ring 7 and cooperates with the limiting groove 1001, so that the annular plate 8 can be driven to move in the vertical direction during the rotation of the limiting shaft 10, thereby driving the sleeve ring 7 and the lever 6 to move upward. This structure is conducive to removing the lever 6 from the solid components precipitated from the bottom of the furnace body 1 and placing it above the solid components. Afterwards, when the plug-in assembly cooperates with the sleeve ring 7, the annular plate 8 can drive the sleeve ring 7 and the lever 6 on its outer side to rotate, so that the precipitated solid components can be evenly located at the bottom of the furnace body 1. On the one hand, it is conducive to the uniform heating of the raw liquid, and on the other hand, it is also conducive to the flow of the raw liquid in the furnace body 1, thereby avoiding affecting the normal distillation.

[0022] like Figure 2-Figure 10 As shown, the above-mentioned plug-in assembly includes a plug-in block 17 that elastically cooperates with the annular plate 8, and the plug-in block 17 is configured as a T-shape as a whole. Fig.10 As shown, the end of the plug-in block 17 close to the collar 7 is an arc surface 20 structure, and the inner wall of the collar 7 is provided with a notch 19 that matches the arc surface 20 structure on the plug-in block 17. When the pressure between the arc surface 20 on the plug-in block 17 and the side edge of the notch 19 increases, one end of the plug-in block 17 can be moved out of the notch 19, so that the connection between the annular plate 8 and the collar 7 is disconnected. In addition, a limit block 16 is elastically installed on the end of the plug-in block 17 away from the collar 7. When the plug-in block 17 is squeezed in a direction away from the collar 7, the limit block 16 can be inserted into the limit groove 1001, so that during the rotation of the limit shaft 10, the cooperation between the limit groove 1001 and the limit block 16 can drive the collar 7 and the annular plate 8 to move upward, thereby moving the lever 6 out of the solid component.

[0023] A connecting ring 11 is sleeved on the outer side of the limiting shaft 10, and the connecting ring 11 can be rotatably connected to the limiting shaft 10 through a bearing, a plug rod 5 is fixedly arranged on the bottom end surface of the connecting ring 11, and a sliding sleeve 9 is fixedly arranged on the top end surface of the annular plate 8, the plug rod 5 passes through the annular plate 8 and the sliding sleeve 9 and slidably cooperates with the two, a clamping block 18 is elastically installed on the inner side surface of the plug rod 5, and a plurality of clamping grooves 901 cooperating with the clamping block 18 are opened on the sliding sleeve 9, and the plurality of clamping grooves 901 are evenly distributed in a linear array, and inclined surfaces 1801 are arranged on both sides of one end of the clamping block 18 placed in the clamping groove 901, and when the pressure between the upper side edge of the clamping block 18 and the inner wall of the clamping groove 901 increases, the clamping block 18 can be moved out of the clamping groove 901, so that the sliding sleeve 9 can move relative to the plug rod 5; The inner wall of the connecting ring 11 is elastically mounted with a protrusion 13, and the top and bottom end surfaces of the protrusion 13 are rotatably mounted with a roller 1301, and an annular groove 1002 is provided on the outer peripheral surface of the limiting shaft 10, and the cross section of the annular groove 1002 is set to be T-shaped, and the protrusion 13 and the roller 1301 are slidably set in the annular groove 1002. Through this structure, the connecting ring 11 and the limiting shaft 10 can be stably matched, refer to Fig. 9 As described, a protrusion 14 is fixedly provided on the inner wall of the annular groove 1002, and one side of the protrusion 14 is provided as an inclined guide surface. When the connecting ring 11 rotates, the protrusion 13 and the roller 1301 will pass through the protrusion 14 from the guide surface. A traction rope 12 is fixedly provided between the protrusion 13 and the block 18, and the traction rope 12 passes through the connecting ring 11 and the insertion rod 5 and slidably cooperates with the two.

[0024] In actual use engineering, as the solvent components in the stock solution gradually evaporate, the solid components in the stock solution will accumulate at the bottom of the furnace body 1 and cover the lever 6, so that the movement of the lever 6 is hindered. When it is necessary to flatten the solid components accumulated at the bottom of the furnace body 1, the connecting ring 11 can be driven to rotate, so that the plug 5 can drive the annular plate 8 to rotate. Since the lever 6 is covered by the precipitated solid components, the lever 6 and the collar 7 are subject to greater resistance and are difficult to move. At this time, during the rotation of the annular plate 8, the pressure between the arc surface 20 on the plug-in block 17 and the notch 19 increases, so that one end of the plug-in block 17 moves out of the notch 19, so that the connection between the annular plate 8 and the collar 7 is disconnected; When the plug-in block 17 is disengaged from the notch 19, the pressure of the inner wall of the collar 7 on the plug-in block 17 enables the plug-in block 17 to move toward the direction close to the limiting shaft 10, so that one end of the limiting block 16 can be inserted into the limiting groove 1001. Since the limiting groove 1001 is spiral, the limiting block 16 can drive the annular plate 8 to move upward during the sliding process along the limiting groove 1001, thereby driving the collar 7 and the lever 6 to move upward, which is conducive to bringing the lever 6 out to the top of the solid component. When the lever 6 moves to the top of the solid component at the bottom of the furnace, When the plug-in block 17 is moved to the slot 19 again so that the arc surface 20 structure on the plug-in block 17 is inserted into the slot 19, the annular plate 8 can drive the collar 7 and the lever 6 to rotate, and the solid components precipitated from the bottom of the furnace body 1 can be flattened by the rotating lever 6. Since the block 18 is provided with an inclined surface 1801, the block 18 can be moved out of the slot 901 during the process of driving the annular plate 8 to move upward by the cooperation between the limit block 16 and the limit slot 1001. When in use, the buoyancy of the lever 6, the ring 7, the sleeve 9 and other structures in the solution is greater than their own gravity, so that the lever 6, the ring 7, the sleeve 9 and other structures can be moved upward by the buoyancy of the solution. In this solution, when the lever 6 is removed from the solid components precipitated from the bottom of the furnace, the lever 6 has a tendency to move upward by the buoyancy of the solution. However, through the cooperation between the block 18 and the slot 901, the lever 6 and other structures will not move upward under the action of buoyancy. Specifically, when the protrusion 13 on the connecting ring 11 rotates to the protrusion 14, the pressure of the protrusion 14 on the roller 1301 can drive the protrusion 13 to move outward. In this process, the protrusion 13 will move one end of the block 18 out of the slot 901 through the traction rope 12, so that the insertion rod 5 and the sleeve 9 are out of cooperation. At this time, under the action of buoyancy, the sleeve 9 and other structures of the lever 6 can be prompted to move upward, and when the protrusion After 13 passes over the protrusion 14, the traction rope 12 is loosened, so that the block 18 can be reset. Therefore, when the sliding sleeve 9 moves upward to align another slot 901 with the block 18, the block 18 can pop out and be inserted into the slot 901, so that the sliding sleeve 9 can be repositioned to prevent it from moving. Repeat the above operation. As the connecting ring 11 rotates, the protrusion 13 and the protrusion 14 can intermittently cooperate, thereby prompting the sliding sleeve 9 to move upward intermittently. During this process, the lever 6 can also move upward intermittently, so as to further flatten the precipitated solid components, which is beneficial to uniformly heating the solution in the furnace body 1. In actual application, when the amount of solution in the furnace body 1 is reduced, the solution can be replenished in time into the furnace body 1 through the liquid inlet pipe. In addition, since the above-mentioned limit shaft 10, sliding sleeve 9, insertion rod 5 and other structures are all assembled on the cover plate 101, when the cover plate 101 is removed, it is beneficial to clean the residue at the bottom of the furnace.

[0025] In summary, this device cooperates with the insertion rod 5 through the provided sliding sleeve 9, so that the sliding sleeve 9 can drive the lever 6 out of the precipitated solid component during the process of rotating the annular plate 8, which is beneficial to flattening the precipitated solid component, and by utilizing the buoyancy of the solution on the sliding sleeve 9 and other structures, the sliding sleeve 9 can move upward intermittently, which can further flatten the precipitated solid component, thereby facilitating uniform heating of the solution in the furnace body 1 and avoiding the solution being affected during flow.

[0026] like Figure 1-Figure 4 As shown, an L-shaped pressure plate is hinged on the outside of the furnace body 1 near the top, and a pressure rod is threadedly connected to the pressure plate. When the pressure plate is flipped over the cover plate 101, the rotating pressure rod can fasten the cover plate 101 to the top of the furnace body 1, thereby sealing the top of the furnace body 1.

[0027] In order to drive the connecting ring 11 to rotate, a connecting pipe 4 is fixedly provided at the top end face of the connecting ring 11, and the connecting pipe 4 can be rotatably connected to the cover plate 101. The connecting pipe 4 is sleeved on the outside of the limiting shaft 10, and a driven gear is fixedly sleeved on the outside of the connecting pipe 4. A rotating shaft 3 is rotatably installed at the cover plate 101, and a driving gear meshing with the driven gear is fixedly sleeved on the rotating shaft 3. Through this structure, the connecting ring 11 can be driven to rotate, and a motor is installed on the cover plate 101. The motor output shaft is connected to the rotating shaft 3 through transmission, so as to drive the rotating shaft 3 to rotate.

[0028] A stopper may be fixedly mounted on the bottom end of the insertion rod 5 to prevent the insertion rod 5 from being separated from the annular plate 8 .

[0029] The sliding sleeve 9 is provided with a through slot along its axial direction, so that the insertion rod 5 can pass through the through slot, and the above-mentioned clamping slot 901 is provided at the inner wall of the through slot.

[0030] like Figure 7-10 As shown, a groove is provided on the inner wall of the connecting ring 11 for slidingly cooperating with the protrusion 13, and a first spring is fixedly arranged between the inner end surface of the groove and the protrusion 13.
