[0054] Example Two

[0055] As Figures 1 - 13 shown, a preparation device, an outer ball sleeve 3 and an inner ball sleeve 21 are rotatably arranged in the evaporation kettle 1, and the outer ball sleeve 3 is sleeved outside the inner ball sleeve 21 and rotates in the opposite direction to the inner ball sleeve 21;

[0056] An inner flow cavity is formed between the outer ball sleeve 3 and the inner ball sleeve 21;

[0057] The outer flow cavity formed between the evaporation kettle 1 and the outer ball sleeve 3 is communicated with the inner flow cavity;

[0058] An outer spiral plate 32 fixedly installed on the outer wall of the outer ball sleeve 3 and located in the outer flow cavity, and an inner spiral plate 24 fixedly installed on the outer wall of the inner ball sleeve 21 and located in the inner flow cavity.

[0059] Specifically, through slots 31 arranged in a circumferential array are formed on the outer wall of the outer ball sleeve 3, a support sleeve 15 is fixedly installed at the bottom in the evaporation kettle 1, a plurality of upper through slots 17 communicating with the inner flow cavity are formed on the support sleeve 15, and a plurality of lower through slots 16 communicating with the outer flow cavity are further formed on the support sleeve 15. Therefore, the upper through slots 17 and the lower through slots 16 on the support sleeve 15 and the through slots 31 on the outer ball sleeve 3 are used to communicate the outer flow cavity and the inner flow cavity. At the same time, the inner ball sleeve 21 is rotatably arranged at the top of the support sleeve 15, and the outer ball sleeve 3 is sleeved and rotates on the outer wall of the support sleeve 15.

[0060] When the inner ball sleeve 21 rotates forward, the outer ball sleeve 3 rotates in the opposite direction at this time. Since the outer spiral plate 32 moves in the outer flow cavity formed between the evaporation kettle 1 and the outer ball sleeve 3, the outer spiral plate 32 rotates with the reverse rotation of the outer ball sleeve 3 to push the liquid in the outer flow cavity upward, and enters the inner flow cavity along a plurality of through slots 31. At the same time, the inner ball sleeve 21 rotates forward so that the inner spiral plate 24 rotates with the forward rotation of the inner ball sleeve 21 to push the liquid in the inner flow cavity downward.

[0061] Furthermore, under the rotation and promotion of the inner spiral plate 24 and the outer spiral plate 32, the liquid in the outer flow cavity is pushed upward and flows into the inner flow cavity, while the liquid in the inner flow cavity is pushed downward and enters the support sleeve 15 along the upper through slot 17. The liquid in the support sleeve 15 accumulates and enters the outer flow cavity along the lower through slot 16. Furthermore, under the rotation and promotion of the inner spiral plate 24 and the outer spiral plate 32, the circulation of the liquid between the outer flow cavity and the inner flow cavity is realized.

[0062] Further, the side of the outer spiral plate 32 can be attached to the inner wall of the evaporation kettle 1. Furthermore, during the rotation of the outer spiral plate 32, the inner wall of the evaporation kettle 1 is scraped, so as to prevent the liquid heated on the inner wall of the evaporation kettle 1 from adhering to the inner wall of the evaporation kettle 1, so as to affect the heating between the overall liquid and the inner wall of the evaporation kettle 1.

[0063] At present, for the evaporation container of the evaporation liquid, when the liquid contacts the inner wall of the container, due to the evaporation of water, the liquid is concentrated, and the concentrated liquid is easy to adhere to the inner wall, and the adhered liquid will affect the heating of the overall liquid. Therefore, the side of the outer spiral plate 32 is attached to the inner wall of the evaporation kettle 1, and during the rotation of the outer spiral plate 32, the inner wall of the evaporation kettle 1 is scraped, so as to avoid the problem that the concentrated liquid is easy to adhere to the inner wall of the evaporation kettle 1.

[0064] Furthermore, for the heating method of the evaporation kettle 1, the outer wall of the evaporation kettle 1 can be burned to transfer heat to the inside of the evaporation kettle 1; or the outer wall of the evaporation kettle 1 can be heated by an electric heating wire to transfer heat to the inside of the evaporation kettle 1; or any heating method known to those skilled in the art for heating the liquid in the evaporation kettle 1 can be used.

[0065] Moreover, the evaporation kettle 1 can be made of a stainless steel kettle.

[0066] The way that the outer ball sleeve 3 and the inner ball sleeve 21 rotate and maintain opposite directions can be to drive the outer ball sleeve 3 and the inner ball sleeve 21 to rotate and maintain opposite directions respectively through two motors and gears; or to drive the outer ball sleeve 3 and the inner ball sleeve 21 to rotate and maintain opposite directions through a motor cooperating with planetary gears; or any way known to those skilled in the art to drive the outer ball sleeve 3 and the inner ball sleeve 21 to rotate and maintain opposite directions can be used.

[0067] As an embodiment provided by the present invention, it further includes an air guide cylinder 4 fixedly installed on the evaporation kettle 1, and the inner ball sleeve 21 is rotatably arranged on the outer wall of the air guide cylinder 4. A blower 41 is connected and arranged at the top end of the air guide cylinder 4.

[0068] Specifically, as Figure 1 shown, the air guide cylinder 4 is respectively fixedly installed on the top of the evaporation kettle 1 through the support rods 14 symmetrically and fixedly installed thereon. At the same time, a liquid inlet 42 arranged obliquely upward is fixedly connected to the air guide cylinder 4. An exhaust pipe 12 communicating with the inside of the evaporation kettle 1 is fixedly installed on the top of the evaporation kettle 1. The air outlet end of the blower 41 is inserted into the top end of the air guide cylinder 4, and the blower 41 is fixedly installed on the air guide cylinder 4.

[0069] Furthermore, the liquid material is poured along the liquid inlet 42, and then under the action of the inclination of the liquid inlet 42, it flows into the air guide cylinder 4. By driving the outer ball sleeve 3 and the inner ball sleeve 21 to rotate in the evaporation kettle 1, and then turning on the blower 41 to blow air into the liquid material in the evaporation kettle 1. The blower 41 can be a temperature-controlled blower. By blowing hot air through the temperature-controlled blower, the evaporation of water vapor in the liquid material can be further accelerated. Secondly, the boiling liquid material will evaporate water vapor. Since the blower 41 blows air into the liquid material, the air blown in will be discharged along the exhaust pipe 12 at this time. At the same time, the steam in the evaporation kettle 1 is accelerated to leave the evaporation kettle 1 under the action of the blower 41, thereby reducing the influence of the water vapor contacting the inner wall of the evaporation kettle 1 and condensing into liquid again on the evaporation of the moisture of the liquid material.

[0070] As a further embodiment provided by the present invention, it further includes a planetary gear assembly for driving the outer ball sleeve 3 and the inner ball sleeve 21 to rotate synchronously and in opposite directions, and the planetary gear assembly includes a main shaft rod 63 that rotates synchronously with the outer ball sleeve 3 and the inner ball sleeve 21.

[0071] Specifically, as Figure 2 shown, a fixed sleeve 2 is fixedly installed on the inner ball sleeve 21, and the fixed sleeve 2 and the inner ball sleeve 21 are respectively sleeved on the air guide cylinder 4. The fixed sleeve 2 is rotatably arranged on the evaporation kettle 1. The planetary gear assembly further includes a main planetary gear 5 fixedly installed on the outer wall of the fixed sleeve 2; a sun gear 51 axially rotatably arranged on the inner wall of the evaporation kettle 1; a cylindrical gear 52 fixedly installed on the inner wall of the outer ball sleeve 3. As Figure 7 shown, the sun gear 51 meshes with the main planetary gear 5 and the cylindrical gear 52 respectively. At the same time, as Figure 8As shown, the planetary gear assembly further includes a drive shaft rod 61 axially rotatably arranged at the top of the evaporation kettle 1 and a force-bearing gear 65 fixedly installed on the outer wall of the fixed sleeve 2. A sealing sheath 13 is fixedly installed at the top of the evaporation kettle 1. A main motor 6 is fixedly installed on the inner wall of the sealing sheath 13, and the top end of the drive shaft rod 61 is fixedly installed on the output end of the main motor 6. A main shaft rod 63 is axially rotatably arranged at the top of the evaporation kettle 1. Pulley members 62 are respectively fixedly installed on the outer walls of the main shaft rod 63 and the drive shaft rod 61, and the two pulley members 62 are driven by a belt. An auxiliary gear 64 fixedly installed on the outer wall of the main shaft rod 63 meshes with the force-bearing gear 65.

[0072] Further, the drive shaft rod 61 is driven to rotate by the main motor 6, and then the two pulley members 62 between the main shaft rod 63 and the drive shaft rod 61 are driven by a belt to rotate the main shaft rod 63. Then, the auxiliary gear 64 on the main shaft rod 63 meshes with the force-bearing gear 65 to rotate the fixed sleeve 2 on the evaporation kettle 1. Due to the rotation of the fixed sleeve 2, the main planetary gear 5 meshes with the sun gear 51 to rotate the sun gear 51. Then, the rotation of the sun gear 51 causes the cylindrical gear 52 to rotate. Thus, the main planetary gear 5, the sun gear 51, and the cylindrical gear 52 in the planetary gear assembly cause the outer ball sleeve 3 and the inner ball sleeve 21 to rotate synchronously and reversely in the evaporation kettle 1. At the same time, when the outer ball sleeve 3 and the inner ball sleeve 21 rotate synchronously and reversely.

[0073] As the optimal embodiment provided by the present invention, a discharge pipe 11 communicating with the inside of the evaporation kettle 1 is fixedly installed at the bottom of the evaporation kettle 1, and a sealing block 8 movably arranged in the vertical direction in the discharge pipe 11 is lifted to open the discharge pipe 11 when the outer spiral plate 32 rotates to push the liquid material.

[0074] Specifically, the discharge pipe 11 communicates with the support sleeve 15.

[0075] Further, by using the main motor 6 to rotate forward to drive the drive shaft rod 61 to rotate, and then through the belt drive of the two pulley members 62 between the main shaft rod 63 and the drive shaft rod 61, the main shaft rod 63 is rotated. Then, the auxiliary gear 64 on the main shaft rod 63 meshes with the force-bearing gear 65 to rotate the fixed sleeve 2 on the evaporation kettle 1. Due to the rotation of the fixed sleeve 2, the main planetary gear 5 and the sun gear 51 mesh to rotate the sun gear 51. Then, the rotation of the sun gear 51 causes the cylindrical gear 52 to rotate. Thus, through the main planetary gear 5, the sun gear 51 and the cylindrical gear 52 in the planetary gear assembly, the inner ball sleeve 21 rotates forward, and the outer ball sleeve 3 rotates in the reverse direction. Since the outer spiral plate 32 moves in the outer flow cavity formed between the evaporation kettle 1 and the outer ball sleeve 3, at this time, the outer spiral plate 32 rotates with the reverse rotation of the outer ball sleeve 3 to push the liquid in the outer flow cavity upward and enter the inner flow cavity along a plurality of through slots 31. At the same time, the inner ball sleeve 21 rotates forward to cause the inner spiral plate 24 to rotate with the forward rotation of the inner ball sleeve 21 to push the liquid in the inner flow cavity downward.

[0076] Furthermore, under the rotational pushing of the inner spiral plate 24 and the outer spiral plate 32, the liquid in the outer flow cavity is pushed upward and flows into the inner flow cavity, while the liquid in the inner flow cavity is pushed downward and enters the support sleeve 15 along the upper through slot 17. The liquid in the support sleeve 15 accumulates and then enters the outer flow cavity along the lower through slot 16. Thus, under the rotational pushing of the inner spiral plate 24 and the outer spiral plate 32, the circulation of the liquid between the outer flow cavity and the inner flow cavity is realized.

[0077] Similarly, when the liquid in the evaporation kettle 1 is completely evaporated, by driving the main motor 6 to rotate in the reverse direction, and then under the reverse rotation of the main motor 6, the inner ball sleeve 21 rotates in the reverse direction and the outer ball sleeve 3 rotates in the forward direction, as Figure 4 shown. At this time, the outer spiral plate 32 rotates with the forward rotation of the outer ball sleeve 3 to push the liquid in the outer flow cavity downward and accumulate at the bottom of the evaporation kettle 1, as Figure 5 shown. Through the lower through slot 16 on the support sleeve 15, the liquid in the outer flow cavity enters the support sleeve 15 along the lower through slot 16. At this time, by driving the sealing block 8 to lift vertically to open the discharge pipe 11, the liquid in the support sleeve 15 is discharged from the evaporation kettle 1 along the opened discharge pipe 11. Therefore, the rotation of the outer ball sleeve 3 accelerates the discharge of the liquid in the outer flow cavity from the evaporation kettle 1.

[0078] Further, when the inner ball sleeve 21 rotates in the reverse direction and the outer ball sleeve 3 rotates in the forward direction, as Figure 4 shown. At this time, the inner spiral plate 24 rotates with the reverse rotation of the inner ball sleeve 21 to push the liquid in the inner flow cavity upward, and then enters the outer flow cavity along a plurality of through slots 31.

[0079] Furthermore, the way the sealing block 8 is driven to lift vertically can be by an electric push rod; it can also be by a motor cooperating with a lead screw and a nut; or any other way known to those skilled in the art to drive the sealing block 8 to lift vertically is acceptable.

[0080] As another embodiment provided by the present invention, the pull rod 73 provided on the sealing block 8 moves vertically within the air guide cylinder 4, and there is a transmission cooperation between the toothed rod 72 fixedly installed on the pull rod 73 and the main shaft rod 63 to have an upper end position and a lower end position in the vertical direction.

[0081] Specifically, the sealing block 8 is rotatably arranged at the bottom end of the pull rod 73, the toothed rod 72 is fixedly installed on the pull rod 73, and the toothed rod 72 is slidably arranged on the air guide cylinder 4.

[0082] As Figure 8 and Figure 12 shown, a follower gear 7 and a transmission shaft rod 67 are axially rotatably arranged on the inner wall of the sealing sheath 13. A first pulley 71 is fixedly installed on the shaft rod of the follower gear 7, and a second pulley 68 is fixedly installed on the outer wall of the transmission shaft rod 67. The first pulley 71 and the second pulley 68 are belt-driven, and at the same time, a wedge gear 66 that meshes with each other is fixedly installed at one end of the transmission shaft rod 67 and the top end of the main shaft rod 63 respectively.

[0083] As Figure 8 shown, elastic plates 43 are symmetrically and fixedly installed on the air guide cylinder 4 on the moving path of the toothed rod 72. At the same time, as Figure 11 shown, a sealing airbag pad 18 is fixedly installed on the inner wall of the discharge pipe 11.

[0084] Therefore, when the main motor 6 rotates forward to drive the drive shaft rod 61 to rotate, and then through the belt drive of the two pulley parts 62 between the main shaft rod 63 and the drive shaft rod 61, the main shaft rod 63 rotates. Then, in cooperation with the auxiliary gear 64, the force-bearing gear 65, the main planetary gear 5, the sun gear 51, and the cylindrical gear 52, the inner ball sleeve 21 rotates forward, and the outer ball sleeve 3 rotates reversely. Furthermore, by using the forward rotation of the inner ball sleeve 21 and the reverse rotation of the outer ball sleeve 3, the liquid material in the evaporation kettle 1 is stirred. At the same time, due to the rotation of the main shaft rod 63, the wedge gears 66 between the main shaft rod 63 and the transmission shaft rod 67 mesh with each other, and then the transmission shaft rod 67 rotates. Then, the first pulley 71 and the second pulley 68 are belt-driven to make the follower gear 7 rotate. When the follower gear 7 rotates, at this time, the follower gear 7 meshes with the toothed rod 72, and then the toothed rod 72 moves downward and presses the elastic plate 43 to store energy. At this time, the toothed rod 72 is at the lower end position, and at the same time, the sealing block 8 on the pull rod 73 moves downward with the toothed rod 72 to fit on the sealing airbag pad 18. Then, the discharge pipe 11 is blocked by the sealing block 8 and the sealing airbag pad 18. The sealing airbag pad 18 can adopt a high-temperature resistant airbag.

[0085] The liquid in the middle area of ​​the currently commonly used evaporation container is heated more slowly because it is far away from the inner wall of the container, which will affect the overall evaporation effect of the liquid.

[0086] Therefore, in order to uniformly heat the liquid in the evaporator 1, Figure 6 As shown, a coiled first heating wire 9 is fixedly installed in the evaporator 1, and a coiled second heating wire 91 is fixedly installed in the inner ball sleeve 21. The first heating wire 9 is used to heat the evaporator 1, and then the heat of the evaporator 1 is transferred to the liquid in the outer flow cavity. At the same time, the second heating wire 91 is used to heat the inner ball sleeve 21, and then the heat of the inner ball sleeve 21 is transferred to the liquid in the inner flow cavity.

[0087] The first heating wire 9 and the second heating wire 91 are used to heat the liquid in the inner flow cavity and the outer flow cavity at the same time, thereby enhancing the uniformity of the liquid being heated. The heating method of the first heating wire 9 and the second heating wire 91 is a well-known technical means for those skilled in the art, and will not be described in detail here.

[0088] When the liquid in the evaporator 1 is completely evaporated, the main motor 6 is driven to rotate in the reverse direction, and then the inner ball sleeve 21 rotates in the reverse direction under the reverse rotation of the main motor 6, and the outer ball sleeve 3 rotates forward, such as Figure 4 As shown, at this time, the outer spiral plate 32 rotates with the outer spherical sleeve 3 in the positive direction to push the liquid in the outer flow cavity to move downward and accumulate at the bottom of the evaporator 1, as shown in FIG. Figure 5 As shown, the liquid in the outer flow cavity flows into the support sleeve 15 along the lower groove 16 through the lower groove 16. At the same time, due to the reverse rotation of the main motor 6, the main shaft rod 63 rotates in the opposite direction. At this time, the elastic force of the elastic plate 43 and the sealing airbag cushion 18 pushes the gear rod 72 upward and meshes with the follower gear 7 again, so that the gear rod 72 moves upward and pushes the elastic plate 43 to store force under the rotation of the follower gear 7. At this time, the gear rod 72 is located at the upper end position, and then the teeth of the follower gear 7 continue to move the teeth of the gear rod 72 to keep the gear rod 72 in the state of compressing the elastic plate 43 to store force, as shown in FIG. Figure 9 and Figure 10 As shown, as the gear rod 72 moves upward, the sealing block 8 at the bottom of the pull rod 73 moves upward accordingly, and then the sealing block 8 moves up in the vertical direction to open the discharge pipe 11, so that the liquid in the support sleeve 15 is discharged from the evaporator 1 along the opened discharge pipe 11. Therefore, the main motor 6 is rotated forward and reversely to control the sealing block 8 to open and close the discharge pipe 11 and drive the inner ball sleeve 21 to rotate forward and the outer ball sleeve 3 to rotate reversely to stir the liquid; the inner ball sleeve 21 rotates reversely and the outer ball sleeve 3 rotates forward to squeeze and accelerate the liquid to gather in the support sleeve 15, and then enter the discharge pipe 11 along the support sleeve 15 to discharge the liquid.

[0089] As another embodiment provided by the present invention, the gear rod 72 is in the upper stop position and the auger fixedly installed at the bottom of the lower sealing block 8 is located in the evaporating kettle 1.

[0090] Specifically, the auger includes a vertical rod 86 fixedly installed at the bottom of the sealing block 8 and a spiral blade 87 on the outer wall of the vertical rod 86 .

[0091] Due to the poor fluidity of the evaporated liquid, in order to accelerate the discharge of the evaporated liquid along the discharge pipe 11, when the inner ball sleeve 21 rotates in the reverse direction and the outer ball sleeve 3 rotates in the forward direction, the outer spiral plate 32 squeezes and accelerates the liquid to gather in the support sleeve 15, and then flows along the support sleeve 15 to the discharge pipe 11. At this time, the rotation of the follower gear 7 causes the gear rod 72 to move up and push the elastic plate 43 to store force. At this time, the gear rod 72 is located at the upper stop position, and then the teeth of the follower gear 7 continue to move the teeth of the gear rod 72 to keep the gear rod 72 in the state of compressing the elastic plate 43 to store force, as shown in FIG. Figure 9 and Figure 10 As shown, the sealing block 8 at the bottom of the pull rod 73 moves upward due to the upward movement of the gear rod 72, and then the sealing block 8 moves upward in the vertical direction to open the discharge pipe 11, and the upward movement of the sealing block 8 causes the auger to be located in the support sleeve 15 and the discharge pipe 11 in the evaporator 1. At this time, the sealing block 8 is driven to rotate to drive the auger to rotate, and then the spiral blade 87 pushes the evaporated liquid in the support sleeve 15 and the discharge pipe 11 to move downward under the rotation of the auger, and finally discharges the evaporator 1 along the discharge pipe 11. Therefore, the rotation of the auger can accelerate the outflow of the evaporated liquid.

[0092] The sealing block 8 may be driven by a motor to rotate and drive the auger to rotate; it may also be manually coordinated with a gear shaft, etc.; or any other method known to those skilled in the art to drive the sealing block 8 to rotate.

[0093] As another embodiment provided by the present invention, the gear rod 72 is in the upper stop position and the lower sealing block 8 is coupled and rotated with the inner ball sleeve 21 .

[0094] Specifically, in order to drive the sealing block 8 to rotate, the inner ball sleeve 21 is provided with a protrusion 22 inside the support sleeve 15 , and a high temperature resistant and non-slip rubber pad 23 is fixedly installed at the bottom of the protrusion 22 .

[0095] Therefore, when the main motor 6 is reversed to make the inner ball sleeve 21 rotate in the opposite direction, and the outer ball sleeve 3 rotates forward, the outer spiral plate 32 on the outer ball sleeve 3 squeezes, shovels and scrapes the evaporated liquid on the inner wall of the evaporator 1 to accelerate the evaporated liquid to be collected in the support sleeve 15, and then flows along the support sleeve 15 to the discharge pipe 11. At this time, the driven gear 7 rotates to make the gear rod 72 move up, as shown in FIG. Figure 9 and Figure 10As shown, as the blocking block 8 at the bottom of the pull rod 73 moves upward along with the toothed rod 72, the blocking block 8 moves upward in the vertical direction to open the discharge pipe 11. And due to the upward movement of the blocking block 8, the auger is located in the support sleeve 15 and the discharge pipe 11 inside the evaporation kettle 1. At the same time, along with the upward movement of the blocking block 8, the blocking block 8 gradually approaches the convex part 22, and finally the blocking block 8 closely fits on the high-temperature resistant anti-slip rubber pad 23 on the convex part 22. At this time, the toothed rod 72 pushes the elastic plate 43 to store energy, and the toothed rod 72 is located at the upper end position. Then, the teeth of the follower gear 7 continuously push the teeth of the toothed rod 72 to keep the toothed rod 72 in the state of compressing the elastic plate 43 to store energy, and at the same time, the blocking block 8 keeps fitting on the high-temperature resistant anti-slip rubber pad 23.

[0096] Since the blocking block 8 is rotatably arranged at the bottom of the pull rod 73, and due to the friction force between the high-temperature resistant anti-slip rubber pad 23 and the blocking block 8 and the upward pulling force of the pull rod 73 on the blocking block 8, the coupling of the blocking block 8 and the inner ball sleeve 21 is completed. At this time, the blocking block 8 and the inner ball sleeve 21 rotate in the same reverse direction. Thus, under the rotation of the blocking block 8, the blocking block 8 drives the auger to rotate so that the spiral blade 87 pushes the evaporated liquid material in the support sleeve 15 and the discharge pipe 11 to move downward, and finally discharges from the evaporation kettle 1 along the discharge pipe 11. Thereby accelerating the downward movement of the evaporated liquid material.

[0097] As another embodiment provided by the present invention, a plurality of valve components are arranged on the blocking block 8. When the toothed rod 72 is at the upper end position, the blocking block 8 is located at the bottom end of the air guide cylinder 4, and the valve components are communicated with the air guide cylinder 4.

[0098] Specifically, in order to be able to perform a certain cooling operation when the evaporated liquid material is discharged along the discharge pipe 11, when the main motor 6 reverses to make the inner ball sleeve 21 rotate in the reverse direction and the outer ball sleeve 3 rotates in the forward direction, the outer spiral plate 32 on the outer ball sleeve 3 squeezes and scrapes the evaporated liquid material on the inner wall of the evaporation kettle 1 to accelerate the collection of the evaporated liquid material in the support sleeve 15, and then flows into the discharge pipe 11 along the inside of the support sleeve 15. At this time, under the rotation of the follower gear 7, the toothed rod 72 moves upward, as Figure 9 and Figure 10As shown in the figure, as the tooth bar 72 moves upward, the sealing block 8 at the bottom of the pull rod 73 also moves upward. Then, the sealing block 8 moves upward in the vertical direction to open the discharge pipe 11. And because of the upward movement of the sealing block 8, the auger is located in the support sleeve 15 and the discharge pipe 11 inside the evaporation kettle 1. At the same time, along with the upward movement of the sealing block 8, the sealing block 8 gradually approaches the bottom end of the convex part 22 and the air guide cylinder 4, and then the sealing block 8 closely fits on the high-temperature resistant anti-slip rubber pad 23 on the convex part 22. At the same time, because the air guide cylinder 4 is located inside the inner ball sleeve 21, at this time, the sealing block 8 cooperates with the convex part 22 and the high-temperature resistant anti-slip rubber pad 23 to block the bottom end of the air guide cylinder 4. At the same time, because the sealing block 8 fits on the high-temperature resistant anti-slip rubber pad 23, at this time, the tooth bar 72 pushes the elastic plate 43 to store energy, and the tooth bar 72 is located at the upper stop position. Then, the teeth of the follower gear 7 continuously push the teeth of the tooth bar 72 to keep the tooth bar 72 in the state of compressing the elastic plate 43 to store energy. At the same time, the sealing block 8 keeps the state of fitting on the high-temperature resistant anti-slip rubber pad 23.

[0099] Since the sealing block 8 is rotatably arranged at the bottom of the pull rod 73, and due to the frictional force between the high-temperature resistant anti-slip rubber pad 23 and the sealing block 8 and the upward pulling force of the pull rod 73 on the sealing block 8, the coupling of the sealing block 8 and the inner ball sleeve 21 is completed. At this time, the sealing block 8 and the inner ball sleeve 21 rotate in the opposite direction synchronously. Thus, under the rotation of the sealing block 8, the sealing block 8 drives the auger to rotate, so that the spiral blade 87 pushes the evaporated liquid material in the support sleeve 15 and the discharge pipe 11 to move downward, and finally discharges from the evaporation kettle 1 along the discharge pipe 11.

[0100] At this time, the valve assembly can be controlled to be opened so that the valve assembly is communicated with the air guide cylinder 4. Then, the air blown by the blower 41 into the air guide cylinder 4 acts on the evaporated liquid material on the auger at the bottom of the sealing block 8 along the valve assembly. Thus, the air blown by the air guide cylinder 4 is used to cool the evaporated liquid material that is being discharged along the discharge pipe 11 to a certain extent. At the same time, the air blowing can also accelerate the flow and fall of the evaporated liquid material to increase the falling speed of the evaporated liquid material.

[0101] Furthermore, the valve assembly can adopt an electronic air valve; a pneumatic valve; or any valve assembly method well-known to those skilled in the art is acceptable.

[0102] As the optimal embodiment further provided by the present invention, the valve assembly includes a plurality of exhaust ports 81 opened on the sealing block 8 and sealing plates 85 slidably arranged in the exhaust ports 81. The plurality of sealing plates 85 are respectively fixedly installed on a pressure ring 83 slidably arranged on the top of the sealing block 8. And the pressure ring 83 and the inner ball sleeve 21 are in a blocking and disassembling fit so that the sealing plates 85 slide to open the exhaust ports 81.

[0103] Specifically, as Figure 11As shown, a plurality of return springs 84 are fixedly installed at the bottom end of the pressing ring 83, and one end of each return spring 84 is fixedly installed on the sealing block 8. An inclined portion 82 is provided on the inner wall on one side of the exhaust port 81. The pressing ring 83 is pushed by the return springs 84 so that the pressing ring 83 protrudes from the top of the sealing block 8. At the same time, a plurality of sealing plates 85 move upward with the pressing ring 83 respectively and are respectively attached to the inclined portion 82 in the exhaust port 81, and then the exhaust port 81 is closed by the inclined portion 82 and the sealing plates 85.

[0104] When it is necessary to evaporate the liquid in the evaporation kettle 1, first start the main motor 6 to rotate forward, and then use the main motor 6 to drive the drive shaft 61 to rotate. Then, through the two pulley members 62 between the main shaft 63 and the drive shaft 61, belt transmission is carried out to make the main shaft 63 rotate. Then, in cooperation with the auxiliary gear 64, the force-bearing gear 65, the main planetary gear 5, the sun gear 51 and the cylindrical gear 52, the inner ball sleeve 21 rotates forward, and the outer ball sleeve 3 rotates reversely. Then, by using the forward rotation of the inner ball sleeve 21 and the reverse rotation of the outer ball sleeve 3 to stir the liquid in the evaporation kettle 1. At the same time, due to the rotation of the main shaft 63, the wedge-shaped gears 66 between the main shaft 63 and the transmission shaft 67 are engaged with each other, and then the transmission shaft 67 rotates. Then, the first pulley 71 and the second pulley 68 are in belt transmission to make the follower gear 7 rotate. When the follower gear 7 rotates, at this time, the follower gear 7 is engaged with the rack 72, and then the rack 72 moves downward and squeezes the elastic plate 43 to store energy. At this time, the rack 72 is located at the lower end position. At the same time, the sealing block 8 on the pull rod 73 moves downward with the rack 72 and is attached to the sealing airbag pad 18, and then the discharge pipe 11 is blocked by the sealing block 8 and the sealing airbag pad 18.

[0105] Then, the liquid is poured along the liquid inlet 42. Then, under the action of the inclination of the liquid inlet 42, it flows into the air guide cylinder 4 and finally flows into the evaporation kettle 1. Then, start the main motor 6 to rotate forward again. At this time, the inner ball sleeve 21 rotates forward and the outer ball sleeve 3 rotates reversely. Since the outer spiral plate 32 moves in the outer flow cavity formed between the evaporation kettle 1 and the outer ball sleeve 3, at this time, the outer spiral plate 32 rotates with the reverse rotation of the outer ball sleeve 3 to push the liquid in the outer flow cavity upward and enter the inner flow cavity along a plurality of through slots 31. At the same time, the inner ball sleeve 21 rotates forward to make the inner spiral plate 24 rotate with the forward rotation of the inner ball sleeve 21 to push the liquid in the inner flow cavity downward.

[0106] Then, under the rotation and pushing of the inner spiral plate 24 and the outer spiral plate 32, the liquid in the outer flow cavity is pushed upward and flows into the inner flow cavity, and the liquid in the inner flow cavity is pushed downward and enters the support sleeve 15 along the upper through slot 17. The liquid in the support sleeve 15 accumulates and enters the outer flow cavity along the lower through slot 16. Then, under the rotation and pushing of the inner spiral plate 24 and the outer spiral plate 32, the circulation of the liquid between the outer flow cavity and the inner flow cavity is realized.

[0107] Furthermore, the first heating wire 9 and the second heating wire 91 are used to heat the liquid in the inner flow cavity and the outer flow cavity at the same time, thereby enhancing the uniformity of the liquid being heated. At the same time, the blower 41 is turned on, and the air blown by the blower 41 is blown along the air guide tube 4 to blow air into the liquid in the evaporator 1. The blower 41 can be a temperature-controlled fan, and the temperature-controlled fan blows hot air to further accelerate the evaporation of water vapor in the liquid. Secondly, the boiling liquid will evaporate water vapor. Since the blower 41 blows air into the liquid, the gas blown in at this time will be discharged along the exhaust pipe 12. At the same time, the steam in the evaporator 1 is accelerated to leave the evaporator 1 under the action of the blower 41, thereby reducing the water vapor from contacting the inner wall of the evaporator 1 and condensing into liquid again to affect the evaporation of the water content of the liquid.

[0108] Furthermore, when the evaporation process of the liquid is completed, the main motor 6 is driven to rotate in the reverse direction. At this time, the main motor 6 drives the shaft 61 again and makes the driving shaft 61 rotate in the reverse direction. Then, the two belt wheels 62 between the main shaft 63 and the driving shaft 61 are used for belt transmission to make the main shaft 63 rotate in the reverse direction. Then, the auxiliary gear 64, the force gear 65, the main planetary gear 5, the sun gear 51 and the cylindrical gear 52 are matched to make the inner ball sleeve 21 rotate in the reverse direction, and the outer ball sleeve 3 rotates in the forward direction. Figure 4 As shown, at this time, the outer spiral plate 32 rotates with the outer ball sleeve 3 in the positive direction to push the liquid in the outer flow cavity to move downward and accumulate at the bottom of the evaporator 1, as shown in FIG. Figure 5 As shown, the liquid in the outer flow cavity flows into the support sleeve 15 along the downward groove 16 through the downward groove 16 on the support sleeve 15. At the same time, due to the reverse rotation of the main motor 6, the main shaft 63 rotates in the opposite direction. At this time, the elastic force of the elastic plate 43 and the sealing airbag cushion 18 pushes the gear rod 72 upward and meshes with the follower gear 7 again, so that the gear rod 72 moves upward under the rotation of the follower gear 7, as shown in FIG. Figure 9 and Figure 10 As shown, as the gear rod 72 moves upward, the sealing block 8 at the bottom of the pull rod 73 moves upward accordingly, and then the sealing block 8 moves vertically to open the discharge pipe 11, so that the liquid in the support sleeve 15 is discharged from the evaporator 1 along the opened discharge pipe 11.

[0109] And due to the upward movement of the sealing block 8, the auger is located in the support sleeve 15 and the discharge pipe 11 inside the evaporation kettle 1. Meanwhile, along with the upward movement of the sealing block 8, the sealing block 8 gradually approaches the bottom end of the convex part 22 and the air guide cylinder 4, and then the sealing block 8 closely adheres to the high-temperature resistant anti-slip rubber pad 23 on the convex part 22. At this time, the tooth bar 72 pushes the elastic plate 43 to store energy, and the tooth bar 72 is located at the upper end stop position. Then, the teeth of the follower gear 7 continuously push the teeth of the tooth bar 72 to keep the tooth bar 72 in a state of compressing the elastic plate 43 to store energy. Due to the frictional force between the high-temperature resistant anti-slip rubber pad 23 and the sealing block 8 and the upward pulling force of the pull rod 73 on the sealing block 8, the coupling of the sealing block 8 and the inner ball sleeve 21 is completed. At this time, the sealing block 8 and the inner ball sleeve 21 rotate in opposite directions synchronously. Thus, under the rotation of the sealing block 8, the sealing block 8 drives the auger to rotate, so that the spiral blade 87 pushes the evaporated liquid in the support sleeve 15 and the discharge pipe 11 to accelerate downward movement, and finally discharges along the discharge pipe 11 out of the evaporation kettle 1. At the same time, because the sealing block 8 adheres to the high-temperature resistant anti-slip rubber pad 23, as Figure 9 and Figure 13 shown, the pressure ring 83 is blocked by the high-temperature resistant anti-slip rubber pad 23 on the inner ball sleeve 21 and retracts into the sealing block 8. Due to the sliding of the pressure ring 83, it drives a plurality of sealing plates 85 to move downward respectively with the pressure ring 83. At this time, the sealing plates 85 in the plurality of exhaust ports 81 move downward away from the inclined part 82 respectively, thereby causing a dislocation between the inclined part 82 and the sealing plate 85 to open the exhaust ports 81. And because the plurality of exhaust ports 81 are respectively located at the bottom end of the air guide cylinder 4, therefore, through the air blowing of the air guide cylinder 4, the evaporated liquid being discharged along the discharge pipe 11 is cooled to a certain extent. At the same time, the air blowing can also accelerate the flow and fall of the evaporated liquid, so as to increase the falling speed of the evaporated liquid.

[0110] Furthermore, by the forward rotation of the main motor 6, the stirring of the liquid material is realized; the sealing block 8 moves downward to block the exhaust port 81. By the reverse rotation of the main motor 6, the outer spiral plate 32 rotates to push the liquid material in the outer flow cavity to move downward and stack the material; the sealing block 8 opens the exhaust port 81; the sealing block 8 and the inner ball sleeve 21 are coupled to make the auger rotate to push the evaporated liquid to move downward; the opening and closing of the exhaust port 81 are controlled and other effects, thereby making the evaporation and discharge process of the liquid material faster and more convenient.
