Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing equipment technology, and in particular to a discharge device and a reaction vessel. Background Technology
[0002] In the chemical industry, reactors are core equipment, undertaking key processes such as material mixing and reaction. As industrial production demands increasingly higher product quality, production efficiency, and equipment stability, the stability and safety of the reactor discharge process have become crucial aspects of the overall process flow.
[0003] In existing technologies, the discharge port of a reactor is located at the bottom or lower side wall of the reactor body. Its basic structure involves a circular or square opening at the corresponding location within the reactor body, connected to a discharge pipe via a flange. The discharge pipe is typically a straight pipe, directly connected to the discharge port. After the material completes its reaction within the reactor, it is propelled from the discharge port into the discharge pipe by its own gravity or external pressure (such as compressed air), and then discharged from the reactor. Some discharge port structures may incorporate simple valves to control the discharge of material.
[0004] From the existing structure described above, when material enters the discharge pipe directly from the reactor, it is propelled out of the pipe at a high velocity under the influence of gravity or pressure. When material suddenly enters the relatively narrow discharge pipe from the larger space inside the reactor, the flow velocity increases instantaneously. This high-speed flow of material exerts a significant impact force on the container wall. Firstly, the high-speed impact easily leads to splashing. In chemical production, splashed material can pollute the surrounding environment, especially for toxic, harmful, flammable, or explosive materials. Splashing not only causes safety accidents but also wastes materials and increases production costs. Secondly, continuous high-intensity impact can damage the container. Long-term exposure to such impact forces can cause wear, deformation, and even cracks in the container wall, shortening its service life. Utility Model Content
[0005] The purpose of this invention is to provide a discharge device and a reaction vessel, which solves the problem that in the prior art, when the reaction vessel discharges materials, the material flow rate is relatively fast and the impact force is large, which on the one hand easily causes material splashing and accidents, and on the other hand easily damages the container.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] In a first aspect, this utility model provides a discharge device, which includes:
[0008] The discharge pipe is connected at one end to the discharge port of the reactor;
[0009] A buffer block is provided at the other end of the discharge pipe and has a buffer space and a discharge hole, the discharge hole being connected to the container;
[0010] A buffer assembly is disposed within the buffer space to buffer the material discharged from the discharge pipe.
[0011] Optionally, the buffer component includes:
[0012] A buffer section is provided in the buffer space and extends partially into the discharge pipe. The end of the buffer section extending into the discharge pipe has an outwardly convex buffer arc surface.
[0013] Optionally, the buffer component further includes:
[0014] The column is fixedly connected at one end to the buffer part and at the other end to the buffer block, so that a discharge space communicating with the discharge hole is formed between the buffer part and the buffer block.
[0015] Optionally, the discharge device further includes:
[0016] A protective cover is fitted onto the end of the discharge pipe furthest from the reactor and fixedly connected to a buffer block. The protective cover is detachably connected to the discharge pipe.
[0017] Optionally, the discharge hole extends in a curved manner along the material flow channel direction.
[0018] Optionally, the bottom wall of the buffer space has a protrusion such that the bottom wall of the buffer space is inclined toward the discharge hole.
[0019] Optionally, the sidewalls of the buffer space extend at an angle.
[0020] Optionally, the inner diameter of the discharge pipe decreases from the end closer to the reactor to the end closer to the buffer block.
[0021] Optionally, both the buffer block and the buffer assembly are provided with a smooth layer.
[0022] Secondly, this utility model also provides a reaction vessel, which includes:
[0023] The vessel body has a discharge port;
[0024] The discharge device as described in any one of the first aspects is connected to the discharge port to guide the material inside the kettle into the container.
[0025] The beneficial effects of this utility model are:
[0026] Firstly, during use, the material in the reactor enters the discharge pipe through the outlet and is guided by the discharge pipe to the buffer block. The material first contacts the buffer component, slowing its flow rate. After the flow rate is slowed, it enters the buffer space for further slowing before gradually flowing into the container through the discharge hole. Therefore, this discharge device can significantly slow down the material flow rate during the discharge process. On the one hand, it reduces the possibility of splashing when the material enters the container, reducing the possibility of safety accidents and material waste. On the other hand, it reduces the intensity of the continuous impact of the material on the container, reducing the possibility of wear, deformation, or even cracks, effectively improving the service life of the container and reducing the overall maintenance and replacement costs.
[0027] Secondly, when the reactor is in use, the reactor body is used to stir, mix and react the materials. The processed materials are discharged into the discharge device through the discharge port. The discharge device buffers the materials multiple times to slow down the flow rate of the materials, which not only reduces the possibility of material splashing, but also reduces the impact of the materials on the container, effectively extending the service life of the container.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0038] This utility model discloses a discharge device and a reaction vessel.
[0039] Reference Figures 1 to 4 The discharge device includes a discharge pipe 1, a buffer block 2, and a buffer assembly 3. One end of the discharge pipe 1 is connected to the outlet of the reactor; the buffer block 2 is located at the other end of the discharge pipe 1 and has a buffer space 21 and a discharge hole 22, which is connected to the container; the buffer assembly 3 is located in the buffer space 21 to buffer the material discharged from the discharge pipe 1.
[0040] Specifically, the upper end of the discharge pipe 1 is sealed to the outlet of the reactor via a flange, and the buffer block 2 is connected to the lower end of the discharge pipe 1. The cross-sectional area of the buffer block 2 is larger than that of the discharge pipe 1, so that the discharge pipe 1 can be fully connected to the buffer space 21. The buffer space 21 is formed by the concave top wall of the buffer block 2, and its depth can be equal to or less than half the height of the buffer block 2. A through hole is opened in the bottom wall of the buffer space 21 as a discharge hole 22. The lower end of the discharge hole 22 can be directly connected to the opening of the container, or it can be connected to the container through a pipeline. A buffer assembly 3 is installed in the buffer space 21, corresponding to the discharge pipe 1. The top wall of the buffer assembly 3 can be inclined or curved, so that the material first contacts the buffer assembly 3 when falling, and then gradually enters the buffer space 21.
[0041] During use, the material in the reactor enters the discharge pipe 1 through the outlet and is guided by the discharge pipe 1 to the buffer block 2. The material first contacts the buffer component 3, slowing down its flow rate. After the flow rate is slowed down, it enters the buffer space 21 for further slowing down before gradually flowing into the container through the discharge hole 22. Therefore, this discharge device can significantly slow down the material flow rate during the discharge process. On the one hand, it reduces the possibility of splashing when the material enters the container, reducing the possibility of safety accidents and material waste. On the other hand, it also reduces the intensity of the continuous impact of the material on the container, reducing the possibility of wear, deformation, or even cracks in the container, effectively improving the service life of the container and reducing the overall maintenance and replacement costs.
[0042] Optionally, the buffer assembly 3 includes a buffer section 31. The buffer section 31 is disposed in the buffer space 21 and partially extends into the discharge pipe 1, and the end of the buffer section 31 extending into the discharge pipe 1 has an outwardly convex buffer arc surface.
[0043] Specifically, the buffer section 31 can be a hemispherical structure, so that its top forms a convex buffer arc surface. It should be understood that the buffer section 31 can also be a conical structure, etc., and its outer side wall can also form a buffer arc surface. Part of the buffer section 31 extends into the discharge pipe 1 to receive materials.
[0044] By setting a buffer section 31 with a buffer arc surface, when the material is discharged from the discharge pipe 1, the material can fall directly onto the buffer arc surface and gradually fall into the buffer space 21 along the buffer arc surface, so as to have a significant buffering effect on the material and effectively reduce the flow rate of the material.
[0045] Optionally, the buffer assembly 3 also includes a column 32. One end of the column 32 is fixedly connected to the buffer part 31, and the other end is fixedly connected to the buffer block 2, so that a discharge space communicating with the discharge hole 22 is formed between the buffer part 31 and the buffer block 2.
[0046] Specifically, the column 32 extends vertically, with its upper end fixedly connected to the buffer section 31 and its lower end fixedly connected to the bottom wall of the buffer space 21. The fixing method can be a detachable fixing connection such as snap-fit or screw-fit, or a non-detachable fixing connection such as welding or bonding. There can be only one column 32, or multiple columns can be arranged circumferentially around the buffer section 31.
[0047] By setting up the column 32, the buffer part 31 is suspended and supported in the buffer space 21, so that a discharge space is formed between the buffer part 31 and the bottom wall of the buffer space 21. This provides sufficient space for the opening of multiple discharge holes 22, thereby ensuring that the material can be discharged smoothly through the discharge holes 22 and reducing the possibility of material accumulation in the buffer space 21.
[0048] Optionally, the discharge device also includes a protective cover 4. The protective cover 4 is fitted onto the end of the discharge pipe 1 away from the reactor and is fixedly connected to the buffer block 2. The protective cover 4 is detachably connected to the discharge pipe 1.
[0049] Specifically, the lower end of the protective cover 4 is fixedly connected to the top wall of the buffer block 2. The fixing method can be snap-fit, screw connection, bonding or welding, etc. The upper end of the protective cover 4 is sleeved on the discharge pipe 1. The upper end of the protective cover 4 and the discharge pipe 1 can be detachably connected by snap-fit or threaded connection, etc. The specific connection method can be designed according to the actual installation difficulty. This utility model does not limit it.
[0050] By setting up a protective cover 4, the connection between the buffer block 2 and the discharge pipe 1 can be covered, thereby ensuring that the material will not overflow from the buffer space 21. The protective cover 4 and the discharge pipe 1 are detachably connected, which allows for quick assembly and disassembly of the buffer block 2 and the discharge pipe 1, making it convenient to maintain and clean the buffer block 2 and the protective cover 4.
[0051] Optionally, the discharge hole 22 extends in a curved manner along the material flow path.
[0052] Specifically, multiple discharge holes 22 can be distributed circumferentially along the buffer block 2, and each discharge hole 22 is curved and extended so that the material does not slide directly out of the discharge hole 22, but gradually falls down along the side wall of the discharge hole 22, so as to further buffer the flow rate of the material. The specific number and diameter of the discharge holes 22 can be designed according to the actual required discharge speed, and this utility model does not limit them.
[0053] Optionally, the bottom wall of the buffer space 21 has a protrusion such that the bottom wall of the buffer space 21 is inclined toward the discharge hole 22.
[0054] Specifically, the bottom wall of the buffer space 21, located between two adjacent discharge holes 22, protrudes upwards, so that the bottom wall of the buffer space 21 is partially tilted, thereby allowing the material in the buffer space 21 to slide into the discharge hole 22, reducing the possibility of material accumulation in the buffer space 21.
[0055] Optionally, the sidewalls of the buffer space 21 extend at an angle.
[0056] Specifically, the buffer space 21 is generally inverted cone shape, so that the side walls of the buffer space 21 are inclined and extended, thereby further guiding and gathering the material, ensuring that the material in the buffer space 21 can be concentrated in the area where the discharge hole 22 is opened.
[0057] Optionally, the inner diameter of the discharge pipe 1 decreases from the end closer to the reactor to the end closer to the buffer block 2.
[0058] Specifically, the inner diameter of the discharge pipe 1 decreases, resulting in a larger inner diameter and more space at the end of the discharge pipe 1 closest to the reactor. This prevents a significant increase in the flow velocity of the material upon entering the discharge pipe 1. As the inner diameter decreases, the material gradually comes into contact with the inner wall of the discharge pipe 1, providing a buffering effect and appropriately slowing down the flow velocity, further enhancing the buffering effect. The smaller inner diameter at the end of the discharge pipe 1 closest to the buffer block 2 helps to gather the material, allowing it to concentrate on the buffer assembly 3, thus improving the buffering effect.
[0059] Optionally, both buffer block 2 and buffer assembly 3 are provided with a smooth layer (not shown in the figure).
[0060] Specifically, the smooth layer can be a structure such as a smooth film, which can be coated on the side walls and bottom walls of the buffer space 21 and the outer surface of the buffer block 2. The smooth layer is made of corrosion-resistant material, which can reduce the possibility of material adhering to the surface of the buffer block 2 and the buffer assembly 3, saving material, and can also separate the material from the buffer block 2 and the buffer assembly 3, reducing the corrosion of the buffer block 2 and the buffer assembly 3 by the material.
[0061] The reactor includes a vessel body and a discharge device as described above. The vessel body has a discharge port; the discharge device is connected to the discharge port to guide the material inside the vessel body into a container.
[0062] When in use, the reactor body is used to stir, mix and react the materials. The processed materials are discharged into the discharge device through the discharge port. The discharge device buffers the materials multiple times to slow down the flow rate, which not only reduces the possibility of splashing but also reduces the impact of the materials on the container, effectively extending the service life of the container.
[0063] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
