Abstract
Description
Technical Field
[0001] This utility model belongs to the field of reaction vessel discharge technology, and in particular relates to a reaction vessel discharge anti-splash structure. Background Technology
[0002] In a broad sense, a reaction vessel is a container where physical or chemical reactions occur. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. From the initial feeding to the reaction to the discharge, the pre-set reaction steps can be completed with a high degree of automation. Important parameters such as temperature, pressure, mechanical control (stirring, blowing, etc.), and reactant / product concentrations during the reaction process are strictly controlled. Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. Examples include reactors, reaction vessels, decomposition vessels, and polymerization kettles. Materials generally include carbon manganese steel, stainless steel, zirconium, nickel-based alloys, and other composite materials.
[0003] However, some reactors have relatively simple discharge pipe structures and do not have anti-splash structures. When the reactor finishes the reaction and discharges the material, the raw material flows from top to bottom inside the reactor. Under the influence of gravity, the raw material flows quickly through the discharge pipe and out. At this time, raw material splashing is likely to occur, resulting in raw material spillage and waste, which will reduce the subsequent reaction yield to a certain extent. Utility Model Content
[0004] The purpose of this utility model is to provide a splash-proof structure for discharging material from a reactor. By setting up a double-valve mechanism, when the operator turns the valve handle one turn, a certain amount of raw material located at the upper sealing plate enters the discharge pipe. After being slowed down by the slow-flow mechanism, the material falls onto the lower sealing plate in the seal. The operator continuously turns the valve handle to discharge the slow-flowing raw material in the reactor in sections, thus solving the problem of material splashing that easily occurs when the raw material flows rapidly downward through the discharge pipe under the influence of gravity.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a splash-proof structure for discharge of a reaction vessel, including a discharge pipe, on which a double valve mechanism and a flow-slowing mechanism are provided;
[0007] The dual-valve mechanism includes a bidirectional component, a sealing component, and a limiting component. The bidirectional component includes a fixed shell fixedly connected to the outer wall of the discharge pipe. Two fixed blocks are fixedly connected to the inner wall of the fixed shell. A connecting shaft is rotatably connected to the inner wall of the two fixed blocks. A first bevel gear is fixedly connected to the top and bottom of the connecting shaft. Two rotating shafts are rotatably connected to the inner wall of the fixed shell. A second bevel gear is fixedly connected to the outer wall of the two rotating shafts. Both second bevel gears mesh with the first bevel gear.
[0008] Furthermore, the sealing assembly includes two trapezoidal buffer rings fixedly connected to the inner wall of the discharge pipe, and a sealing sheet is rotatably connected to the inner wall of each of the two trapezoidal buffer rings. The left ends of the two rotating shafts extend to the inner wall of the trapezoidal buffer rings and are fixedly connected to the sealing sheet. A valve handle is rotatably connected to the inner wall of the discharge pipe.
[0009] Furthermore, the right end of the valve handle is fixedly connected to the left end of the rotating shaft, the outer wall of the valve handle is rotatably connected to the inner wall of the discharge pipe, and the outer walls of both rotating shafts are rotatably connected to the inner wall of the discharge pipe.
[0010] Furthermore, the limiting component includes a first limiting groove formed on the inner wall of the discharge pipe, the left end of the upper rotating shaft extends to the inner wall of the first limiting groove and is fixedly connected to a limiting block, the outer wall of the limiting block is rotatably connected to the inner wall of the first limiting groove, and flange rings are fixedly connected to both the top and bottom ends of the discharge pipe.
[0011] Furthermore, the flow control mechanism includes a flow control component and a linkage component. The flow control component includes a second limiting groove formed on the inner wall of the discharge pipe, and a rotating cylinder is rotatably connected to the inner wall of the second limiting groove.
[0012] Furthermore, a plurality of spiral blades are fixedly connected to the inner wall of the rotating drum, and a serrated ring is fixedly connected to the outer wall of the rotating drum.
[0013] Furthermore, the linkage component includes a gear fixedly connected to the outer wall of the connecting shaft, the gear meshing with a sawtooth ring, and the outer wall of the sawtooth ring rotatably connected to the inner wall of the second limiting groove.
[0014] This utility model has the following beneficial effects:
[0015] By setting up a dual-valve mechanism, the operator can rotate the valve handle to rotate the two sealing plates and discharge the raw materials in sections. When the operator rotates the valve handle one turn, a certain amount of raw material located on the upper sealing plate enters the discharge pipe and is then treated by the slow-flow mechanism before falling onto the lower sealing plate. By continuously rotating the valve handle, the operator can discharge the slow-flowing raw materials in sections from the reactor, which to some extent avoids the situation where a large amount of raw material is discharged directly, which could easily lead to splashing and waste.
[0016] 2. By setting up a flow-slowing mechanism, in conjunction with the dual-valve mechanism, the operator can feed the raw materials into the discharge pipe in sections. Simultaneously turning the valve handle will drive several spiral blades to rotate in the opposite direction, which will slow down the flow of the raw materials in the discharge pipe, reduce the direct impact force of the falling raw materials, and facilitate the slow discharge of the raw materials from the discharge pipe through the lower sealing plate. This will reduce the possibility of splashing and further improve the practicality of the device.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-5 As shown, this utility model is a structure for preventing splashing during discharge of a reaction vessel, including a discharge pipe 1, on which a double valve mechanism 2 and a flow slowing mechanism 3 are provided;
[0028] The dual-valve mechanism 2 includes a bidirectional assembly, a sealing assembly, and a limiting assembly. The bidirectional assembly includes a fixed housing 21 fixedly connected to the outer wall of the discharge pipe 1. Two fixed blocks 22 are fixedly connected to the inner wall of the fixed housing 21. A connecting shaft 23 is rotatably connected to the inner wall of the two fixed blocks 22. A first bevel gear 24 is fixedly connected to the top and bottom ends of the connecting shaft 23. Two rotating shafts 25 are rotatably connected to the inner wall of the fixed housing 21. A second bevel gear 26 is fixedly connected to the outer wall of the two rotating shafts 25. Both second bevel gears 26 mesh with the first bevel gear 24.
[0029] Among them, such as Figure 3 , Figure 4 and Figure 5 As shown, the sealing assembly includes two trapezoidal buffer rings 27 fixedly connected to the inner wall of the discharge pipe 1. A sealing sheet 28 is rotatably connected to the inner wall of each trapezoidal buffer ring 27. The left ends of two rotating shafts 25 extend to the inner wall of the trapezoidal buffer rings 27 and are fixedly connected to the sealing sheet 28. A valve handle 29 is rotatably connected to the inner wall of the discharge pipe 1. The right end of the valve handle 29 is fixedly connected to the left end of the rotating shaft 25. The outer wall of the valve handle 29 is rotatably connected to the inner wall of the discharge pipe 1. The outer walls of both rotating shafts 25 are rotatably connected to the inner wall of the discharge pipe 1. The limiting assembly includes a first limiting groove 210 opened on the inner wall of the discharge pipe 1. The left end of the upper rotating shaft 25 extends to the inner wall of the first limiting groove 210 and is fixedly connected to a limiting block 211. The outer wall of the limiting block 211 is rotatably connected to the inner wall of the first limiting groove 210. Flange rings 212 are fixedly connected to both the top and bottom ends of the discharge pipe 1.
[0030] By setting up a dual-valve mechanism 2, the operator can rotate the valve handle 29 to rotate the two sealing plates 28 and discharge the raw materials in sections. When the operator rotates the valve handle 29 one turn, a certain amount of raw material located on the upper sealing plate 28 enters the discharge pipe 1 and is then treated by the slow-flow mechanism 3 before falling onto the lower sealing plate 28 in the seal. The operator can continuously rotate the valve handle 29 to discharge the raw materials in sections from the reactor after the slow-flow process, which to a certain extent avoids the situation where a large amount of raw material is directly discharged, which is prone to splashing and waste.
[0031] Among them, such as Figure 2 , Figure 3 and Figure 4 As shown, the flow control mechanism 3 includes a flow control component and a linkage component. The flow control component includes a second limiting groove 31 opened on the inner wall of the discharge pipe 1. A rotating cylinder 32 is rotatably connected to the inner wall of the second limiting groove 31. Several spiral blades 33 are fixedly connected to the inner wall of the rotating cylinder 32. A toothed ring 34 is fixedly connected to the outer wall of the rotating cylinder 32. The linkage component includes a gear 35 fixedly connected to the outer wall of the connecting shaft 23. The gear 35 meshes with the toothed ring 34. The outer wall of the toothed ring 34 is rotatably connected to the inner wall of the second limiting groove 31.
[0032] By setting up a flow-slowing mechanism 3, in conjunction with the double-valve mechanism 2, the operator can feed the raw material into the discharge pipe 1 in segments. Simultaneously, when the valve handle 29 is turned, it drives several spiral blades 33 to rotate in the opposite direction, which slows down the flow of the raw material in the discharge pipe 1, reduces the direct impact force of the falling raw material, and facilitates the slow discharge of the raw material from the discharge pipe 1 through the lower sealing plate 28. This reduces the possibility of splashing and further improves the practicality of the device.
[0033] A specific application of this embodiment is as follows: By setting a double-valve mechanism 2, the upper flange ring 212 of the discharge pipe 1 is fixed at the discharge port of the reactor. When the reactor needs to discharge after the reaction is completed, the operator can rotate the lower rotating shaft 25 by grasping the valve handle 29. The lower rotating shaft 25 drives the sealing plate 28 to rotate. Since the second bevel gear 26 meshes with the first bevel gear 24, the lower rotating shaft 25 drives the lower first bevel gear 24 to rotate synchronously through the lower second bevel gear 26. The lower first bevel gear 24 drives the upper first bevel gear 24 to rotate synchronously through the connecting shaft 23. Two fixing blocks 22 are set to limit the rotation of the connecting shaft 23. The upper first bevel gear 24 drives the upper second bevel gear 26 meshing with it to rotate synchronously. The upper second bevel gear 26 drives the upper sealing plate 28 to rotate through the upper rotating shaft 25. This completes the rotation of the valve handle 29 and drives the two valves to rotate synchronously. The sealing plate 28 rotates within the trapezoidal buffer ring 27. The inner ring of the trapezoidal buffer ring 27 is designed with an inclined trapezoidal shape, which slows down the flow of raw materials in the discharge pipe 1 and reduces the diameter of the raw materials flowing in and out of the discharge pipe 1, thereby reducing the amount of raw materials flowing out over a period of time. The limiting block 211 and the first limiting groove 210 limit the left end of the upper rotating shaft 25. This allows the operator to rotate the valve handle 29 to rotate the two sealing plates 28 and discharge the raw materials in sections. When the operator rotates the valve handle 29 one turn, a certain amount of raw materials located at the upper sealing plate 28 enters the discharge pipe 1 and is then slowed down by the flow-slowing mechanism 3 before falling onto the lower sealing plate 28 in the seal. By continuously rotating the valve handle 29, the operator discharges the slowed-down raw materials in sections from the reactor, thus avoiding the waste caused by the direct discharge of large amounts of raw materials that could easily splash.
[0034] By setting a flow-retarding mechanism 3, in conjunction with the double-valve mechanism 2, when the operator turns the valve handle 29, the connecting shaft 23 rotates, and the gear 35 on the connecting shaft 23 rotates synchronously. Since the gear 35 meshes with the sawtooth ring 34, the gear 35 drives the rotating drum 32 to rotate in the second limiting groove 31 through the sawtooth ring 34. The rotation of the rotating drum 32 drives several spiral blades 33 inside it to rotate. The operator can continuously turn the valve handle 29 to drive the two sealing plates 28 to flip in the trapezoidal buffer ring 27, so that the raw material on the discharge pipe 1 is intermittently switched between sealed and open states by the rotating sealing plates 28, so that the raw material enters the discharge pipe in segments within a certain period of time. Inside the discharge pipe 1, the continuously rotating valve handle 29 drives several spiral blades 33 to rotate in the opposite direction to the spiral trajectory of the material flow through the connecting shaft 23. While not affecting the flow of raw materials, the spiral blades 33 rotating upwards in the opposite direction help to further slow down the flow rate of the raw materials. This achieves the effect of cooperating with the double valve mechanism 2. When the operator feeds the raw materials into the discharge pipe 1 in sections, the simultaneous rotation of the valve handle 29 drives several spiral blades 33 to rotate in the opposite direction, which slows down the flow of the raw materials in the discharge pipe 1, reduces the direct impact force of the falling raw materials, and facilitates the slow discharge of the raw materials from the discharge pipe 1 through the lower sealing plate 28. This reduces the possibility of splashing and further improves the practicality of the device.
