[0041] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0042] Embodiment 1

[0043] refer to Figure 1-10 As shown, the present invention proposes a reaction kettle with a filtering mechanism, including a kettle body mechanism, which includes a kettle body 1, a kettle cover 2 and a driving member 3. The upper end of the kettle body 1 is fixedly docked with the lower end of the kettle cover 2. The driving member 3 is fixed on the top of the kettle cover 2. When the stirring action is in progress, the driving member 3 is driven by the driving member 3. In this embodiment, the driving member 3 adopts the existing technology, specifically a motor and a differential, which will not be described in detail in this embodiment. The bottom of the kettle body 1 has an open end extending inward;

[0044] Among them, reference Figure 2 The kettle cover 2 is provided with a plurality of inlet and outlet pipe ports, and an observation window and corresponding pressure sensors and temperature sensors are provided at the same time, which are all prior art and meet the actual use requirements. They are not the invention points of the present invention and will not be described in detail. This is only an exemplary description, and other prior art components can also be added as auxiliary. A discharge pipe and a control valve are also provided on the outside of the kettle body 1.

[0045] refer to Figure 3 and Figure 5 An inner kettle cylinder 4 is arranged between the kettle body 1 and the kettle cover 2, and grooves are arranged on the sides of the kettle body 1 and the kettle cover 2 close to the inner kettle cylinder 4, and a sealing gasket is arranged in the groove to seal and fix with the inner kettle cylinder 4 tightly; the lower end of the inner kettle cylinder 4 is fixedly sealed with the opening end, a first accommodating cavity is formed between the inner wall of the kettle cover 2 and the inner wall of the inner kettle cylinder 4, and a second accommodating cavity is formed between the inner wall of the kettle body 1 and the outer wall of the inner kettle cylinder 4;

[0046] It should be noted that the first accommodating chamber can be used to contain the working material of the reactor, and the second accommodating chamber wraps the first accommodating chamber to reduce heat loss;

[0047] refer to Figure 5 The inner kettle cylinder 4 includes a cylinder body 41 and an extension cylinder 42. The extension cylinder 42 is fixed at the lower end of the cylinder body 41 and is connected thereto and is arranged in the open end. The cylinder body 41 includes a radial extension portion and an axial extension portion. The radial extension portion is fixed between the kettle body 1 and the kettle cover 2. The lower end of the axial extension portion narrows toward the axis and is connected to the extension cylinder 42. The material in the cylinder body 41 can slide and fall conveniently through its own gravity and in coordination with its structure to avoid the accumulation of the material on the cylinder body 41. The outer peripheral side of the cylinder body 41 is fixed with an outer heat exchange shell 43 and forms a cavity therewith. Two butt joint ports 44 are arranged on the cylinder body 41. The top of the kettle cover 2 is provided with an external pipe corresponding to the butt joint port 44, and the external pipe is connected to an external circulation device.

[0048] It should be noted that when the outside needs to be heated or cooled, the circulating medium is filled into it through the circulation action of the circulation device and then discharged; the temperature of the cylinder 41 can be easily increased or decreased.

[0049] refer to Figure 3 , Figure 4 and Figure 6 The output end of the driving member 3 is connected to a floating stirring assembly 5, which can adjust the stirring position according to the height of the liquid level in the inner kettle cylinder 4 during operation; the floating stirring assembly 5 includes a plug-in rod 51, a floating empty cylinder 52 and a docking piece 53. The plug-in rod 51 is adapted to be plugged in with the floating empty cylinder 52 and is fixed to the output end of the driving member 3. A hollow cavity is provided in the floating empty cylinder 52. In this embodiment, the plug-in rod 51 is configured as a regular hexagonal rod, and its function is to enable the floating empty cylinder 52 to rotate with the plug-in rod 51 when the plug-in rod 51 rotates, and the plug-in rod 51 and the floating empty cylinder 52 can also slide. In order to achieve the above-mentioned purpose, the plug-in rod 51 can be configured as any prism shape to achieve the above-mentioned purpose. The floating empty cylinder 52 is configured to be hollow, and specific reference is made to Figure 3The purpose of setting it to be hollow is that after the cylinder 41 is filled with materials, the floating hollow cylinder 52 and the plug rod 51 can be adjusted and slid by the buoyancy. The docking piece 53 is fixed to the lower end of the floating hollow cylinder 52 and a plurality of stirring plates 54 are arranged on the outer peripheral side. The stirring plates 54 are arranged obliquely and fixedly formed with the docking piece 53 at an acute angle, which is 60° in this embodiment. The extension path of the stirring plates 54 is centrifugally curved;

[0050] It should be noted that when the floating empty cylinder 52 changes position, its stirring plate 54 is close to the bottom of the cylinder body 41 to avoid excessive scraping with the cylinder body 41 .

[0051] Among them, there are three stirring plates 54 in this embodiment. When it rotates, due to its inclined setting, when the floating empty cylinder 52 rotates, it can form a disturbance with the material filled in the cylinder 41, accelerate the circulation of the internal material and achieve the purpose of uniformity; and the final moving position of the floating empty cylinder 52 can be adjusted by different rotation directions. This includes when it rotates in one direction, due to the inclined setting, the stirring plate 54 contacts the material in the cylinder 41 and generates lift, so that the position of the floating empty cylinder 52 rises, and the disturbance position of the stirring plate 54 changes. When it rotates in the other opposite direction, the stirring plate 54 is close to the inner bottom of the cylinder 41, disturbing the material in the lower half; at the same time, when the cylinder 41 is in an empty state, it can also clean up the material trapped on the inner bottom wall of the cylinder 41, and guide and concentrate the material through the centrifugal bending state and acute angle of the stirring plate 54.

[0052] refer to Figure 3-Figure 5 A filter assembly 6 is movably arranged in the inner kettle cylinder 4, and the filter assembly 6 can be docked or separated with the floating stirring assembly 5. When the floating stirring assembly 5 is docked with the filter assembly 6 and driven by the driving member 3 to rotate in one direction, the filter assembly 6 itself is blocked and changes its shape to an impeller shape to cut with the fluid; when the filter assembly 6 rotates in the opposite direction or is detached from the docking with the floating stirring assembly 5, the filter assembly 6 is in a planar shape to filter the fluid in the first accommodating chamber entering the second accommodating chamber.

[0053] refer to Figure 4 , Figure 7-10 The filter assembly 6 includes a magnetic ring 61, an adjustment rod 62 and a transmission box 63. The magnetic ring 61 is rotatably connected to the inner wall of the extension tube 42. A ball bearing is arranged on the lower side of the magnetic ring 61. A magnetic ring is fixedly arranged on the inner wall of the extension tube 42. On the upper side of the magnetic ring 61, a receiving ring is arranged on the extension tube 42; the magnetic ring 61 can move up and down between the magnetic ring and the receiving ring.

[0054] The adjusting rod 62 is provided with a plurality of rods and one end thereof faces the axis of the magnetic ring 61 and penetrates the transmission box 63 to fix a bevel gear 65. A filter plate 64 is installed on the adjusting rod 62. The contact ends of two adjacent filter plates 64 are provided with inclined surfaces 641, and the surfaces of the same inclined surfaces 641 are parallel. In this embodiment, the number of the adjusting rods 62 is set to six, the transmission box 63 is set to a hexagonal column, and the filter plate 64 is set to a fan shape. For details, please refer to Fig.10 When the filter plates 64 are in a horizontal state, two adjacent filter plates 64 are attached to each other to form a plane and are sealed between the magnetic ring 61 and the transmission box 63. For details, refer to Figure 7 . An adapter column 66 that rotates with the transmission box 63 is provided through the top of the transmission box 63. The adapter column 66 is docked and adapted with the docking piece 53. The upper end of the adapter column 66 is chamfered to facilitate the docking of the adapter column 66 and the docking piece 53. A blocking ring is fixed in the middle of the adapter column 66 to block the docking piece 53 from continuing to descend, so that the docking piece 53 is received. A bevel gear 2 67 is fixed at the lower end of the adapter column 66 to mesh with a plurality of bevel gears 1 65 for transmission. A deflection column 68 is fixed at the lower end of the bevel gear 2 67. The internal fixed limiting member 69 of the transmission box 63 limits the rotation range of the deflection column 68; a deflection cavity 691 is provided in the middle of the limiting member 69, and the deflection column 68 is inserted in the deflection cavity 691 and limits the rotation range of the deflection column 68.

[0055] The deflection cavity 691 limits the rotation range of the deflection column 68, so that the deflection column 68 can move a certain angle in the deflection cavity 691, so that the adjustment rod 62 can reach a certain angle when rotating. In this embodiment, the maximum rotation angle of the filter plate 64 is a horizontal angle of 20°; Fig.10 For this reason, during cleaning, the inclined filter plate 64 is opened so that the surface of the filter plate 64 can directly contact the clean water. The inclined setting can increase the impact of the solid matter that has not been filtered on the surface of the filter plate 64 and the water, which is beneficial to the cleaning itself. At the same time, an opening is formed, which is beneficial to the discharge, so that it is convenient to clean itself and can speed up the cleaning efficiency. The inclined surface 641 set on the filter plate 64 is in the shape of a knife edge, which can cut the material and crush the crystals in the crystallization. At the same time, the filter cake formed by the filtration of ordinary solid substances can also be cut. The impact of the formed filter cake with the surface of the filter plate 64 during the crushing process can also be beneficial to the cleaning of the filter plate 64 itself.

[0056] In this embodiment, after the raw materials are fed into the inner kettle cylinder 4 through an external input pipeline, it takes a certain amount of time for the reaction to occur, during which a stirring operation is also required; the driving action of the driving member 3 drives the plug-in rod 51 to rotate, and the floating empty cylinder 52 matched with it rotates accordingly, and the docking member 53 fixed at the lower end of the floating empty cylinder 52 drives the stirring plate 54 to stir with the raw materials to stir the raw materials; and since the floating empty cylinder 52 is in the raw materials, the floating empty cylinder 52 is subjected to the buoyancy and slides with the plug-in rod 51, thereby adjusting the stirring position of the stirring plate 54. Due to the setting of the stirring plate 54, the moving position of the floating empty cylinder 52 is different according to the different stirring directions; wherein when rotating in one direction, the stirring plate 54 is subjected to the lift force due to the action of the stirring plate 54, and at the same time reaches a certain position, and when it reaches a certain position and cannot move up, the stirring plate 54 will be fixed at this position to disturb and stir the raw materials.

[0057] When the raw materials enter the filtering stage, since the solid matter in the raw materials needs to be filtered, the raw materials are discharged through the valve and the pipeline and filtered through the filter assembly 6; a large amount of solid matter will accumulate on the filter assembly 6, which reduces the filtering capacity. When all the raw materials in the cylinder 41 have passed the filtration, the solid matter accumulated on the filter assembly 6 needs to be cleaned; since the floating empty cylinder 52 is no longer affected by the buoyancy, the docking piece 53 docks with the adapter column 66. After the docking is completed, the magnetic ring 61 is separated from the contact with the magnetic ring and approaches the receiving ring. The filter assembly 6 is driven by the driving action of the driving member 3 through the floating stirring assembly 5 and rotates in one direction. Driven by the adapter column 66 In this way, the bevel gear 2 67 connected to the adapter column 66 meshes with the bevel gear 1 65 to transmit the adjustment rod 62 and the filter plate 64 thereon to deflect together, so that the filter plates 64 change from being in contact with each other to being staggered with each other, forming an impeller shape, and can be deflected to a certain angle by the restriction of the deflection column 68, the restriction member 69 and the deflection cavity 691; then a certain amount of clean water is input into the extension tube 42, so that the filter plate 64 and the clean water impact quickly to achieve self-cleaning effect; when cleaning is completed, a certain amount of clean water can be added, and then the driving member 3 is driven in the reverse direction to make the filter plate 64 return to its position and deflect, realize the closed state, and enter the filtering form; and the magnetic attraction ring 61 is contacted and locked in position with the magnetic attraction ring.
