Based on the embodiments of the present utility model, any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art to all other embodiments obtained without creative effort should be included within the protection scope of the present utility model.

[0016] like Figure 1 , Figure 2 As shown, this embodiment discloses a multifunctional reaction device, including a reaction tank 1. The top of the reaction tank 1 is set with a conical structure.

The bottom of the reaction tank 1 is detachably connected to a bottom plate 2, and a filter mechanism is provided on the bottom plate 2. The outer side of the reaction vessel 1 is equipped with a rotating mechanism, which drives the reaction vessel 1 to rotate.

[0017] The filtration mechanism includes a filter screen 10 and a protective net 8.

Several positioning sleeves 801 are provided at the bottom of the protective net 8, with their tops fixedly connected to the protective net 8. The bottom ends of the positioning sleeves 801 pass through the filter screen 10 and the base plate 2 in sequence and are connected to positioning bolts 802. Several filter coils 9 are evenly arranged on the upper end of the base plate 2, positioned between the base plate 2 and the filter screen 10. The top of each filter coil 9 is open and in contact with the bottom of the filter screen 10. A liquid outlet pipe 901 is provided at the bottom of each filter coil 9, penetrating the bottom end face of the base plate 2. A control valve is provided on the liquid outlet pipe 901. A spacer block 11 is provided between the protective net 8 and the filter net 10 so that a filter cavity 13 is formed between the protective net 8 and the filter net 10; the bottom end of the spacer block 11 is in contact with the top end of the filter net 10, and the top end of the spacer block 11 is in contact with the bottom end of the protective net 8.

The top end of the central pipe 201 passes through the base plate 2 and the filter screen 10 and is connected to the filter chamber 13. A central valve is provided on the central pipe 201.

[0019] In the filtration mechanism, the pore size of the protective mesh is larger than that of the filter mesh to intercept larger solid particles. The protective mesh protects the filter mesh, preventing damage from larger solid particles and extending its service life. Under the initial interception effect of the protective mesh, smaller solid particles and liquid materials enter the filtration chamber. The liquid material is then filtered through the filter mesh, and the filtrate is discharged from the filter coil and outlet pipe. The last remaining liquid in the filtration chamber can be discharged through the central pipe. Next, the control valve and central valve are closed, and water is introduced into the reaction tank. The reaction tank is rotated multiple times to clean the solid particles. After cleaning, the control valve and central valve are opened to discharge the cleaning solution. Finally, the reaction tank is inverted, and the solid particles are discharged through the outlet at the top of the filter tank.

[0020] The edges of the base plate 2 and the reaction vessel 1 are provided with connecting ears 202 and are bolted together. A sealing gasket 12 for sealing is provided between the top of the base plate 2 and the bottom of the reaction vessel 1.

[0022] The rotating mechanism includes a feed pipe 5, a discharge pipe 6, a support platform 3, and a power motor 7. The feed pipe 5 and the discharge pipe 6 are symmetrically arranged on both sides of the center position of the reaction tank 1, and the axial direction of the feed pipe 5 and the discharge pipe 6 is perpendicular to the axial direction of the reaction tank 1. One end of the feed pipe 5 and the discharge pipe 6 is fixedly connected to the outer wall of the reaction tank 1, and the inside of the feed pipe 5 and the discharge pipe 6 is connected to the inside of the reaction tank 1.

[0023] The reaction vessel can be rotated by a motor to clean the filtered solid particles with the washing water flow. At the same time, the rotating mechanism can invert the reaction vessel to facilitate the discharge of the cleaned solid particles.

[0024] The butterfly valve 4 has an exhaust port 401 at its center, and the exhaust port 401 is connected to the air passage interface 501 located on the outer side of the feed pipe 5.

[0025] During feeding, materials can be supplied under positive pressure through the feed pipe. The supplied materials include nitrogen, liquid materials, etc. After the reaction is completed, if the pressure inside the reaction tank is too high, the gas inside the reaction tank can be discharged and collected through the exhaust port.

[0026] The outer circumference of the discharge pipe 6 is provided with a liquid filter interface 601, which is connected to the bottom pipe of the discharge pipe 901.

[0027] During discharge, materials can be discharged through the discharge pipe without affecting the rotation of the rotating mechanism. The discharged materials include filtrate, washing water, etc.

Clean water is then supplied to the filter tank, and a rotating mechanism causes the tank to rotate, cleaning the residual solids. After cleaning, the cleaning water is discharged again through the filtration mechanism. Finally, the rotating mechanism rotates the filter tank until the discharge port faces downwards, and the butterfly valve is opened to remove the cleaned residual solids. This design achieves both filtration of the mixture and cleaning and removal of residual solids, allowing for the selection of either filtrate or solid filter material removal according to reaction requirements, effectively improving the efficiency of the reaction equipment.
