DETAILED DESCRIPTION

[0032] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0033] like Figure 1 As shown, a reaction kettle 1 comprises:

[0034] A feed inlet 11 is used to add solid and liquid substances into the inner cavity of the reactor 1;

[0035] The discharge port 12 is located at the bottom of the reactor 1;

[0036] The adapter 13 is detachably fastened to the discharge port 12 and is provided with a liquid discharge port 131;

[0037] A filter 14 is mounted on the top of the adapter 13;

[0038] The liquid substance can be discharged to the outside through the discharge port 12 , the filter plate 14 and the liquid discharge port 131 in sequence, and the solid substance can be accumulated on the filter plate 14 .

[0039] In the present application, the solid-liquid mixed product obtained after the reaction of the upstream reactor is completed enters the inner cavity of the reactor 1 through the feed port 11. The drain port 131 of the adapter 13 is opened, and the liquid substance in the solid-liquid mixed product is discharged to the outside through the discharge port 12, the filter plate 14 and the drain port 131 in turn under the action of gravity, while the solid substance is accumulated on the filter plate 14. The drain port 131 is closed, and detergent is injected into the inner cavity of the reactor 1 through the feed port 11. After the solid substance is cleaned, the drain port 131 is opened again to discharge the waste liquid to the outside; this is repeated until the cleaning requirements of the solid substance are met. Finally, the adapter 13 carrying the filter plate 14 is removed from the discharge port 12, and the cleaned and filtered solid substance accumulated on the filter plate 14 can be obtained. The present application sets a detachable adapter 13 on the discharge port 12 and sets a filter plate 14 on the top of the adapter 13, so that the solid matter in the solid-liquid mixed product is collected on the adapter 13 after repeated cleaning and filtration. The solid matter can be obtained by removing the adapter 13. The whole process does not require material transfer, thereby solving the problem of cleaning and filtering of solid matter in the solid-liquid mixed product, and achieving the effect of convenient operation and fast processing speed.

[0040] Those skilled in the art will appreciate that the detergent is generally an organic solvent. The reactants may also enter the reactor 1 through the feed port 11, directly undergo a chemical reaction in the reactor 1 and obtain a solid-liquid mixed product, and then continue to clean and filter the solid matter in the reactor 1.

[0041] Specifically, the reactor 1 further includes an air inlet 181 and an exhaust port 182 for introducing an inert gas or a dry gas. In addition to filtering and separating solid matter under normal pressure, the reactor 1 can introduce an inert gas through the air inlet 181 for pressurized filtering and separation, or extract internal gas through the air inlet 181 for vacuum filtering and separation. In addition, the reactor 1 can also introduce dry gas through the air inlet 181, or directly introduce dry gas through the drain port 131, to dry the solid matter collected by the adapter 13.

[0042] Specifically, the reactor 1 also includes a heating jacket (not shown in the figure) mounted on its outer wall surface. The heating jacket is used to increase the inner cavity temperature of the reactor 1, thereby controlling the temperature of the solid matter during cleaning, and also speeding up the drying speed of the solid matter after cleaning and filtration.

[0043] In some embodiments, the reactor 1 can be made of thick-walled glass. The top of the reactor 1 is provided with a plurality of feed ports 11, which are respectively connected to the external reactor and the container pipe filled with detergent, so as to controllably add the solid-liquid mixed product and the detergent into the inner cavity of the reactor 1; furthermore, the discharge port 131 is connected to the external recovery container pipe to controllably discharge the liquid substance from the inner cavity of the reactor 1; furthermore, the top of the reactor 1 is provided with an air inlet 181 and an exhaust port 182 to controllably introduce dry gas into the inner cavity of the reactor 1; thereby realizing the automatic operation of the entire treatment process. One reactor 1 can realize the functions of washing, filtering and drying without manual intervention, while reducing the volatilization of organic matter and ensuring personal safety. After the operation is completed, the solid substance can be obtained by removing the adapter 13, which is easy to operate and can significantly improve the efficiency of the simulation experiment.

[0044] Specifically, the top of the adapter 13 is provided with a first sinking portion 132 connected to the drain port 131, and the first sinking portion 132 is used to form a cavity between the top surface of the adapter 13 and the bottom surface of the filter plate 14. The formation of the cavity is conducive to the liquid material passing through the filter plate 14, flowing to the drain port 131 and being emptied, and avoiding being retained on the bottom surface of the filter plate 14. In addition, the size of the drain port 131 is usually smaller than the size of the filter plate 14, and the first sinking portion 132 can also converge the liquid material passing through the filter plate 14 to the drain port 131.

[0045] Specifically, the top of the adapter 13 is provided with a second sinking portion 133 connected to the drain port 131, and the second sinking portion 133 is used to embed and install the filter 14. The second sinking portion 133 can prevent the filter 14 from being displaced, and can also form a space for collecting solid matter above the filter 14 to prevent the solid matter from accidentally spilling and being lost when the adapter 13 is removed.

[0046] Specifically, the adapter 13 further includes a transfer column 134 and a drain valve 135, and the two ends of the transfer column 134 are respectively connected to the drain port 131 and the drain valve 135. The drain port 131, the transfer column 134 and the drain valve 135 are connected in sequence, and the drain valve 135 can control the opening and closing of the drain port 131.

[0047] In some embodiments, the adapter 13 is sealed and connected to the discharge port 12 via a pipe thread. The top of the adapter 13 is provided with a second sinking portion 133, a first sinking portion 132 and a drain port 131 which are interconnected from top to bottom. The second sinking portion 133 is a countersunk hole, and the first sinking portion 132 is a tapered groove, the lowest position of which vertically penetrates downward to form the drain port 131. The drain port 131, the adapter column 134 and the drain valve 135 are connected and sealed via pipe threads in sequence.

[0048] Specifically, the reactor 1 further includes a support 15 stacked on the filter plate 14, and the support 15 is used to collect solid matter deposited on the filter plate 14. The support 15 is provided with a cavity for accommodating solid matter, which can support the solid matter, thereby increasing the amount of solid matter deposited on the filter plate 14, and preventing the solid matter from accidentally spilling and being lost when the adapter 13 is removed.

[0049] Specifically, the reactor 1 further includes a pressure ring 16 located above the bracket 15 , and the pressure ring 16 is engaged with the top of the adapter 13 , so that the bracket 15 and the filter plate 14 are fixed on the top of the adapter 13 .

[0050] Specifically, the reactor 1 further includes a sealing ring 17 located on the contact surface between the discharge port 12 and the adapter 13. The sealing ring 17 can further improve the sealing performance after the discharge port 12 and the adapter 13 are fastened and connected.

[0051] In some embodiments, the filter 14 is made of sintered glass, and has different aperture specifications according to the particle size of the solid matter to be cleaned and filtered. The bracket 15 is a mesh plate with a certain thickness, and the solid matter is collected in a number of mesh holes. The filter 14 and the bracket 15 are placed in the second sinking part 133 of the adapter 13 in sequence; the pressure ring 16 is a retaining spring, which is clamped in the annular groove of the second sinking part 133, thereby pressing the filter 14 and the bracket 15. The top size of the adapter 13 is reduced to form a step surface; a step surface is also formed at the corresponding position on the discharge port 12; the sealing ring 17 is located at the step surface, and an end face seal is formed after the discharge port 12 is fastened to the adapter 13.

The stirrer 3 drives the stirring shaft 19 to rotate, so that the paddle can stir the solid matter and detergent in the inner cavity of the reactor 1 to improve the cleaning effect of the solid matter, thereby reducing the number of repeated cleaning and filtration times and improving the operating efficiency.

[0056] Specifically, the solid matter cleaning and filtering device further comprises:

[0057] The upper plate 41 is installed on the main frame 2, encircles the upper part of the reaction kettle 1, and is provided with a fixed plate and a detachable clamping plate;

[0058] The lower plate 42 is installed on the main frame 2, supports the bottom of the reactor 1, and is provided with a notch for avoiding the reactor 1;

[0059] The fixing ring 43 is installed on the outer wall of the reactor 1 and is located above the upper plate 41 .

[0060] In the present application, the upper plate 41, the lower plate 42 and the fixing ring 43 are combined to form the installation structure of the reactor 1 on the main frame 2. When installing the reactor 1, first fix the fixing ring 43 on the reactor 1, and remove the clamping plate of the upper plate 41; then place the bottom of the reactor 1 on the lower plate 42, and its top against the fixing plate of the upper plate 41; finally, connect the clamping plate with the fixing plate, so that the reactor 1 is fixed between the upper plate 41 and the lower plate 42 through the fixing ring 43.

[0061] In some embodiments, the reactor 1 is installed in the middle of the main frame 2, and its stirring shaft 19 is arranged vertically.
