Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1

[0033] like Figure 1 - Figure 7 As shown, a chemical synthesis material purification and separation device comprises a separation kettle 1, wherein a rotating rod 4 is rotatably connected inside the separation kettle 1, the rotating rod 4 penetrates the separation kettle 1 and extends to the upper part of the separation kettle 1, a plurality of stirring shafts 5 for fully reacting the materials are fixedly connected to the rotating rod 4, a cleaning mechanism for cleaning the stirring shafts 5 is arranged on the surface of the rotating rod 4, the cleaning mechanism comprises a moving ring 14 sleeved on the surface of the rotating rod 4, the moving ring 14 and the rotating rod 4 are movably connected, a plurality of fourth connecting plates 28 are rotatably connected to the moving ring 14, a cleaning sleeve 31 for cleaning the stirring shaft 5 is rotatably connected on the side of the fourth connecting plate 28 away from the moving ring 14, the cleaning sleeve 31 and the stirring shaft 5 are always kept in contact, the cleaning sleeve 31 and the stirring shaft 5 are slidably connected, a reciprocating mechanism is arranged on the upper part of the separation kettle 1, the reciprocating mechanism drives and controls the operation of the cleaning mechanism, a plurality of nozzles 29 for spraying water to clean the inside of the separation kettle 1 are arranged on the surface of the rotating rod 4, a water supply mechanism is arranged on the upper part of the separation kettle 1, and the water supply mechanism is used to provide a water source to the nozzles 29;

[0034] The reciprocating mechanism includes a fixed plate 2 arranged on the upper part of the separation kettle 1, a motor 9 is fixedly installed on one side of the fixed plate 2, a first rotating shaft 10 is arranged at the output end of the motor 9, the first rotating shaft 10 is rotatably connected to the fixed plate 2, a rotating disk 19 is fixedly connected to the first rotating shaft 10, and two first fixing rods 20 are fixedly connected to the edge of one side of the rotating disk 19 away from the fixed plate 2;

[0035] The side of the fixed plate 2 close to the rotating disk 19 is rotatably connected with the first connecting plate 21, and the first connecting plate 21 is movably connected to the first fixing rod 20. The side of the fixed plate 2 close to the rotating disk 19 is slidably connected with the second connecting plate 22, and the side of the second connecting plate 22 away from the fixed plate 2 is fixedly connected with the second fixing rod 23, and the second fixing rod 23 is slidably connected to the groove provided on the surface of the first connecting plate 21;

[0036] A third connecting plate 24 is fixedly connected to one side of the second connecting plate 22 close to the second fixing rod 23, and the third connecting plate 24 is movably connected to the first fixing rod 20. A push-pull rod 25 is fixedly connected to one side of the second connecting plate 22 close to the separation kettle 1, and a push-pull rod 25 is fixedly connected to the rotating rod 4 of the cleaning mechanism on one side away from the second connecting plate 22.

[0037] The water supply mechanism includes a water tank 3 fixedly connected to the upper part of the separation kettle 1, and a water inlet 16 for adding water to the inside of the water tank 3 is arranged on the upper part of the water tank 3. A water inlet pipe 18 is arranged on the side of the water tank 3 close to the rotating rod 4. The side of the water inlet pipe 18 away from the water tank 3 passes through the rotating rod 4 and extends to the lower part of the rotating rod 4. A water pump 17 is arranged at the connection between the water inlet pipe 18 and the water tank 3.

[0038] In this embodiment, when it is needed to clean the inside of the separation kettle 1 during use, the motor 9 fixedly installed on one side of the fixed plate 2 is started, and the motor 9 drives the first rotating shaft 10 arranged at its output end to rotate. The rotation of the first rotating shaft 10 drives the fixedly connected rotating disk 19 to rotate, and the rotating disk 19 causes the two first fixed rods 20 fixedly connected at the edges to rotate. When one of the first fixed rods 20 rotates to contact the first connecting plate 21, the first fixed rod 20 pushes the first connecting plate 21 to rotate. The rotation of the first connecting plate 21 causes the second connecting plate 22 to move away from the second fixed rod 23 fixedly connected to one side of the fixed plate 2 to slide inside the groove provided on the surface of the first connecting plate 21.

[0039] That is, the first connecting plate 21 will eventually drive the second connecting plate 22 to slide upward through the second fixing rod 23, and the second connecting plate 22 will drive the fixedly connected third connecting plate 24 to slide toward the second fixing rod 23 until the angle of the first connecting plate 21 changes to no longer contact the first fixing rod 20. At this time, the first fixing rod 20 continues to rotate and contacts the third connecting plate 24. At this time, under the action of the first fixing rod 20, the third connecting plate 24 will drive the second connecting plate 22 to slide downward, that is, the rotation of the rotating disk 19 will eventually drive the second connecting plate 22 to slide up and down reciprocatingly on the surface of the fixing plate 2;

[0040] The sliding of the second connecting plate 22 will drive the push-pull rod 25 to slide, and the push-pull rod 25 will drive the moving ring 14 to slide up and down. When the moving ring 14 slides downward, it will drive the rotatably connected fourth connecting plate 28 to rotate. The rotation of the fourth connecting plate 28 will cause the cleaning sleeve 31 rotatably connected to the side of the fourth connecting plate 28 away from the moving ring 14 to slide on the stirring shaft 5. The cleaning sleeve 31 and the stirring shaft 5 always maintain a close connection, which makes it easy for the cleaning sleeve 31 to fully clean the adhesion on the surface of the stirring shaft 5, so as to prevent the adhesion from continuing to participate in the reaction in the next reaction, resulting in a decrease in product purity.

[0043] There are three groups of cleaning mechanisms, the lower part of the cleaning mechanism is fixedly connected with a third fixing rod 30, and the side of the third fixing rod 30 away from the cleaning mechanism is fixedly connected with another group of cleaning mechanisms;

[0044] The first rotating shaft 10 is fixedly connected to a bevel gear set 11, the bevel gear set 11 is fixedly connected to a second rotating shaft 12, the second rotating shaft 12 is rotationally connected to the fixed plate 2, the second rotating shaft 12 is transmission-connected to a belt 13, and the belt 13 is transmission-connected to the rotating rod 4;

[0045] A cleaning head 27 for cleaning the inner wall of the separation kettle 1 and limiting the cleaning sleeve 31 is fixedly connected to the side of the stirring shaft 5 away from the rotating rod 4, and a limiting wheel 26 for limiting the second connecting plate 22 is provided on the side of the fixed plate 2 close to the second connecting plate 22, and the limiting wheel 26 and the second connecting plate 22 are in rolling connection.

[0046] In this embodiment, the feed port 15 provided at the upper part of the separation kettle 1 is convenient for adding materials into the separation kettle 1 during purification and separation. The support columns 8 provided at the lower part of the separation kettle 1 are multiple, which is convenient for supporting the separation kettle 1. The discharge pipe 6 and the suction pump 7 provided at the lower part of the separation kettle 1 are convenient for discharging materials after purification and separation and discharging cleaning liquid and residues after cleaning the inside of the separation kettle 1.

[0047] The two adjacent cleaning mechanisms are fixedly connected by the third fixing rod 30, so that the three cleaning mechanisms arranged inside the separation kettle 1 can be operated simultaneously. When the motor 9 is started to drive the reciprocating mechanism to operate, the first rotating shaft 10 can rotate the fixedly connected bevel gear set 11, and the bevel gear set 11 can rotate the fixedly connected second rotating shaft 12, and the second rotating shaft 12 can drive the rotating rod 4 to rotate through the belt 13, so that the rotating rod 4 can be rotated when the inside of the separation kettle 1 is cleaned, and the multiple nozzles 29 arranged on the surface of the rotating rod 4 can rotate to spray water, thereby solving the problem of cleaning dead corners and ensuring that all areas inside the separation kettle 1 can be fully cleaned;

[0048] The cleaning head 27 arranged on the side of the stirring shaft 5 away from the rotating rod 4 is convenient for cleaning the inner wall of the separation kettle 1, and can also limit the cleaning sleeve 31 attached to the surface of the stirring shaft 5 to prevent the cleaning sleeve 31 from detaching.
