[0001] The utility model belongs to the technical field of chemical equipment, and particularly relates to a devolatilization device. Background Art
[0002] The redistribution plate is one of the essential parts in the devolatilization equipment.

At the same time, in order to ensure that the downward liquid has a large enough surface area so that the volatile medium contained therein can be completely removed. In addition, the existing redistribution devolatilization plate has a thick plate thickness, a large amount of material, and a small fluid channel area per unit cross-sectional area, resulting in high production costs.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0040] like Figure 1-Figure 5 As shown, a devolatilization device is provided in this embodiment, including an equipment body 1, a support ring plate 2, an arch plate 3 and a feed pipe assembly 4, wherein an air suction port 6 is provided on the upper part of the equipment body 1. The support ring plate 2 is provided on the inner side wall of the equipment body 1, and is spaced apart from the air suction port 6 by a first preset distance in the vertical direction. The arch plate 3 is provided on the support ring plate 2, and the arch plate 3 includes at least two groups of side plates 32, and a horizontal plate 33 connected to the bottom end of the side plate, and the tops of two adjacent groups of side plates 32 are connected, and a first devolatilization hole 38 is provided on the horizontal plate 33, and a second devolatilization hole 37 is provided on the side plate 32. A discharge port 40 is provided on the feed pipe assembly 4, and the discharge port 40 is provided above the arch plate 3 and located between two adjacent groups of arch plates 3.
[0041] In this embodiment, the arched plate 3 includes at least two groups of side panels 32, and the top ends of the two adjacent groups of side panels 32 are connected. The top ends of the two adjacent groups of side panels 32 can be directly connected or indirectly connected. Specifically, the top ends of the side panels 32 are all arc structures, and the arc structures of the two adjacent groups of side panels are connected. The arc radius of the arc structure of each group of side panels can be the same or different. It is also possible that a flat plate is provided between the top ends of the two adjacent groups of side panels 32, and the two groups of side panels 32 are connected via the flat plate. It is also possible that an arc plate 31 is provided between the top ends of the two adjacent groups of side panels 32, and the two groups of side panels 32 are connected via the arc plate 31.
[0042] In this embodiment, the arch plate 3 is arranged on the support ring plate 2, and the arch plate 3 is fixedly connected to the support ring plate 2. Since the distance between the support ring plate 2 and the air outlet 6 is a first preset distance, the arch plate 3 is located at a specific position in the middle of the equipment body 1 after installation.
[0043] In addition, because the feed pipe assembly 4 is connected to an external liquid conveying structure, the material flows out through the discharge port 40, and the material will flow and spread on the arch plate 3, and the material will flow downward to the bottom of the equipment body 1 through the first devolatilization hole 38 on the horizontal plate of the arch plate 3. Because the material has a certain viscosity, part of the material will accumulate between the two groups of arch plates 3. When the material accumulates to a certain extent, it will flow downward through the second devolatilization hole 37 on the side wall of the arch plate 3 to avoid the accumulation of the material on the arch plate 3.
[0044] A liquid outlet is provided near the bottom of the equipment body 1, through which the material in the equipment body 1 is discharged. The gas generated during the devolatilization of the material goes up through the second devolatilization holes 37 on the side wall of the arch plate 3 and is discharged through the exhaust port 6. This process further concentrates the material and increases the mass fraction of the material, and the generated gas is discharged through the exhaust port 6.
[0045] Preferably, the arched plates 3 include at least two groups, and the arched plates 3 are arranged in parallel and side by side. By increasing the number of the arched plates 3 and providing the side plates 32, the surface area of the material devolatilization is further increased, and the devolatilization efficiency is improved. The distance between two adjacent groups of arched plates 3 can be the same or different. The installation is adjusted according to actual needs.
[0046] In this embodiment, the additional arch plate 3 makes the devolatilization area of the material larger than the cross-sectional area of the equipment body 1, and the second devolatilization hole 37 is opened on it, which can greatly increase the surface area of the material, thereby increasing the devolatilization area of the material. At the same time, the arched structure of the arch plate 3 is conducive to the downward movement of liquid in the material and the upward movement of gas, which can fully improve the devolatilization efficiency of the material.
[0047] Compared with the existing redistribution plates, the arched plate 3 in this embodiment is configured to be arched, and therefore, the thickness requirement of the arched plate 3 is low, thereby saving materials and reducing production costs.
[0048] Preferably, the size and number of the arched plates 3 are selected and determined according to the size of the device body 1 .
[0049] Preferably, the device body 1 comprises a device cylinder and a device head 5 , and the device head 5 is welded to the upper end of the device cylinder. The air extraction port 6 is provided in the device head 5 .
[0050] Preferably, the arch plate 3 includes two sets of side plates 32, an arc plate 31 is arranged between the two sets of side plates 32, and the two sets of side plates 32 are symmetrically and obliquely arranged on both sides of the arc plate 31, and a first preset angle is formed between the two sets of side plates 32. The bottom ends of the two sets of side plates 32 are connected to a horizontal plate 33, and the horizontal plate 33 is provided with a first mounting hole 20, and the horizontal plate 33 is connected to the support ring plate 2 through the first mounting hole 20.
[0051] Preferably, along the length direction of the arch plate 3, first mounting holes 20 are provided at both ends of the horizontal plate 33, and the horizontal plate 33 is fixedly connected to the supporting ring plate 2 through the first mounting holes 20. Figure 4 As shown, a group of first mounting holes 20 are respectively provided at both ends of each horizontal plate 33. A connecting plate 34 arranged in the vertical direction is connected to one side of the horizontal plate 33, and a second mounting hole 36 is provided on the connecting plate 34. Two adjacent groups of connecting plates 34 are connected via the second mounting holes 36. The above-mentioned "one side of the horizontal plate 33" refers to an end of the horizontal plate 33 away from the side plate 32 in the width direction of the arch plate 3.
[0052] Alternatively, in other embodiments, the arch plate 3 includes two groups of side plates 32, the two groups of side plates 32 are connected via an arc plate 31, an arc plate 31 is arranged between the two groups of side plates 32, the two groups of side plates 32 are symmetrically and obliquely arranged on both sides of the arc plate 31, and a first preset angle is formed between the two groups of side plates 32. The bottom ends of the two groups of side plates 32 are connected to a horizontal plate 33, and the horizontal plate 33 is provided with a first mounting hole 20. The horizontal plate 33 is connected to the support ring plate 2 via the first mounting hole 20, and the two adjacent groups of arch plates 3 are connected via the second mounting hole 36. Further preferably, along the length direction of the arch plate 3, the first mounting holes 20 are respectively provided at both ends of the horizontal plate 33, and the horizontal plate 33 is fixedly connected to the support ring plate 2 via the first mounting hole 20.
[0053] Preferably, the second devolatilization holes 37 are arranged on the side plates 32, and multiple rows of second devolatilization holes 37 are arranged in sequence on each side plate 32 along the height direction of the side plates 32. Specifically, the number of the second devolatilization holes 37 in each row is determined according to actual needs. After the material flows out through the discharge port 40, it falls and is spread on the horizontal plate 33 of the arch plate 3. The material flows down through the first devolatilization holes 38 on the horizontal plate 33. Because the material has a certain viscosity, the material accumulated between the two adjacent groups of arch plates 3 flows down through the second devolatilization holes 37 on the side plates 32, which maximizes the devolatilization of the material. Because the material is spread on the arch plate 3, a material layer will be formed, and the upward gas is not easy to pass through the first devolatilization holes 38 and the second devolatilization holes 37 covered by the material layer. In this embodiment, multiple rows of second devolatilization holes 37 are arranged on the side plate 32 on each side, and the accumulated material layer is not sufficient to completely cover the second devolatilization holes 37, so that the gas generated below the arch plate 3 during the devolatilization process can go up through the second devolatilization holes 37, ensuring that the material is fully devolatilized.
[0054] Exemplarily, a plurality of rows of first devolatilization holes 37 arranged in parallel are provided on each side plate 32, and the central axes of the second devolatilization holes 37 in the adjacent upper and lower rows along the inclined direction of the side surface are coaxial.
[0055] The sizes and shapes of the second devolatilization holes 37 in each row may be the same or different. The sizes and shapes of the second devolatilization holes 37 in each row may be the same or different.
[0056] Further preferably, the first devolatilization hole 38 is a first strip hole, the long axis of which is arranged along a first direction, the first direction is located in a horizontal plane, and is perpendicular to the horizontal axis of symmetry of the arch plate 3. The first strip hole is arranged so that the material laid on the side plate 32 can flow downward quickly through the first strip hole for devolatilization. The length direction in this embodiment refers to Figure 3 Horizontal direction in .
[0057] The second devolatilization hole 37 is a second strip hole, and the projection of the long axis of the second strip hole in the horizontal plane is arranged along the first direction. For example, the long axis of the second strip hole can also be arranged along the length direction of the arch plate 3. The length direction in this embodiment refers to Figure 2 The installation direction of the arched plate 3 in.
[0058] Preferably, if Figure 4As shown, the first mounting hole 20 is a first circular hole. The arch plate 3 and the support ring plate 2 are fixedly connected through the first circular hole. Preferably, because the support ring plate 2 is annular, the first mounting holes 20 on all the arch plates 3 are arranged along the circumferential direction. Because multiple groups of arch plates 3 are arranged side by side and in parallel, the first mounting holes 20 are arranged at both ends and sides of the arch plates 3 on both sides of the edge, and the first mounting holes 20 are arranged at both ends of the arch plates 3 located in the middle.
[0059] Since the fixed connection between the arched plate 3 and the supporting ring plate 2 is only fixedly connected at the two ends of the arched plate 3 and the supporting ring plate 2, when the outflow of the material from the discharge port 40 of the feed pipe assembly 4 is large, it accumulates between the two adjacent groups of arched plates 3, generating pressure on the arched plates 3. Therefore, in order to improve the bearing capacity of the arched plate 3, the two adjacent groups of arched plates 3 are fixedly connected via the second mounting holes 36.
[0060] Further preferably, the second mounting hole 36 is a second circular hole. Figure 2 As shown, the second mounting hole 36 is a fourth strip hole, and the long axis of the fourth strip hole is arranged in the vertical direction. Alternatively, the second mounting hole 36 is a U-shaped hole. The relative positions of the two adjacent groups of arch plates 3 are adjusted by the second mounting hole 36 to avoid position interference when the two adjacent groups of arch plates 3 are installed. Exemplarily, the second mounting hole 36 is a U-shaped hole, and along the length direction of the arch plate 3, the two adjacent groups of U-shaped holes are spaced apart by a third preset distance, and the long axis of the U-shaped hole is arranged in the vertical direction. The purpose of setting it as a U-shaped hole is to facilitate installation and disassembly. The two adjacent groups of arch plates 3 are connected by bolts passing through the U-shaped hole.
[0061] Preferably, along the length direction of the arched plate 3 , the second mounting holes 20 on the connecting plate 34 on the same side of the same arched plate 3 are evenly distributed.
[0062] Preferably, the horizontal plate 33 is further provided with first devolatilization holes 38, which are evenly arranged on the horizontal plate 33. The material flowing out of the discharge port 40 first passes through the horizontal plate 33, and flows down through the first devolatilization holes 38 on the horizontal plate 33. The material that does not flow down in time accumulates on the horizontal plate 33 to form a material layer. After the material gradually accumulates to the height of the second devolatilization holes 37, it flows down through the second devolatilization holes 37, further improving the devolatilization efficiency of the material.
[0063] For example, Figure 2 As shown, the first devolatilization hole 38 and the second devolatilization hole 37 are consistent in shape and size.
[0064] In addition, the support ring plate 2 is welded to the side wall of the equipment body 1 to ensure the connection strength of the support ring plate 2. Preferably, a reinforcing rib 21 is provided between the support ring plate 2 and the equipment body 1 to improve the structural strength of the support ring plate 2. Further preferably, the reinforcing rib 21 is evenly distributed along the circumference of the support ring plate 2 to ensure that the support ring plate 2 is evenly stressed. In other embodiments, no reinforcing rib may be provided between the support ring plate 2 and the equipment body 1.
[0065] In other embodiments, a mounting piece is further provided on the support ring plate 2, and both ends of the mounting piece 2 are fixed on the support ring plate 2, and the arch plate 3 is fixed to the mounting piece. The supporting strength of the arch plate 3 is increased by providing the mounting piece.
[0066] Further preferably, the horizontal plate 33 is also provided with a fixing hole, through which the fixing hole is fixedly connected to the mounting member. The fixing hole is a circular hole. Or the fixing hole is a fifth bar hole, and the size and shape of the fifth bar hole are determined according to actual needs.
[0067] Preferably, the arched plate 3 is made of steel plate.
[0068] Preferably, the openings at both ends of the arched plate 3 are provided, or the openings at both ends of the arched plate 3 are provided with fully enclosed baffles or partial baffles at the same time.
[0069] Specifically, the openings at both ends of the arch plate 3 may be provided with no baffles, closed baffles, or partial baffles. Since there is a gap between the arch plate 3 and the inner wall of the equipment body 1, when the flow rate of the material is large, no baffles may be provided, or partial baffles may be provided, and the material inside the arch plate 3 flows out through the openings at the ends. When the flow rate of the material is small, closed baffles may be provided at the ends of the arch plate 3, and all the material flows down through the second devolatilization holes 37.
[0070] Preferably, the discharge port 40 provided on the feed pipe assembly 4 is directly opposite to the middle position of the two adjacent groups of arched plates 3. This arrangement ensures that the material flowing down from the discharge port 40 flows onto the horizontal plate 33 of the arched plate 3, so that the material is more evenly distributed on the arched plate 3, and the material accumulates above the horizontal plates 33 of the two groups of arched plates 3, and slowly flows down through the second devolatilization holes 37.
[0071] Preferably, the feed pipe assembly 4 comprises a main pipe section 41 and a plurality of branch pipe sections 42 connected thereto, and the opening of the branch pipe section 42 is a discharge port 40. Further preferably, the branch pipe section 42 is welded to the main pipe section 41. Further preferably, the plurality of branch pipe sections 42 are arranged in parallel.
[0072] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
