Description

Technical Field

[0001] This utility model relates to the field of reaction equipment technology, and in particular to a reaction vessel. Background Technology

[0002] The reaction between materials is the core of chemical production, and the chemical reactor that carries out the reaction is also a core component of chemical equipment. The reaction vessel is one of the most commonly used chemical reactors. In the production process, the vast majority of reactions are liquid-solid phase reactions. The two phases of materials undergo stirring, mixing, pressurization, and heating inside the reaction vessel to complete the reaction and finally obtain the desired product.

[0003] After the reaction in the reactor is complete, the materials need to be separated into solid and liquid phases for further processing. However, in existing technologies, solid-liquid separation is often achieved by installing a filter plate at the reactor's outlet. The liquid phase is filtered through the filter plate first, then the filter plate is removed, and the remaining solid material in the reactor is collected. This method is cumbersome, has low filtration efficiency, and does not allow for the collection and testing of the solid material during the reaction process. Utility Model Content

[0004] This invention provides a reaction vessel to solve the problems mentioned in the background art.

[0005] This utility model provides a reaction vessel, including a support and a distribution box disposed below the support. The reaction vessel body is mounted on the support through a circular hole. The bottom of the reaction vessel body has a discharge port, which is connected to the inlet at the top of the distribution box via a discharge valve. A drain port is also provided at the bottom of one side wall of the distribution box. A filter box communicating with the inlet is fixedly installed inside the distribution box. At least two drawers are movably installed inside the filter box, one above the other. A handle is installed on the outer side of one side wall of each drawer. The drawers are accessed and removed through slots on the distribution box and the filter box. When the drawers are closed, the side wall with the handle is flush with the slot. Filter holes are provided on the left and right side walls and bottom of the filter box and the drawers.

[0006] Optionally, a motor is installed on the top of the reactor body, and the output end of the motor passes through the top of the reactor body and is connected to the stirring device. The top of the reactor body is also provided with a solid material inlet and a liquid material inlet.

[0007] Optionally, the bottom of the reactor body is an inverted cone-shaped structure, and the discharge port is located at the end of the inverted cone-shaped structure.

A straight scraper abutting against the inner wall of the reactor body is connected to the end of each horizontal support rod. An inclined support rod is installed below the horizontal support rods, and an inclined scraper abutting against an inverted conical structure is connected to the end of each inclined support rod. Stirring blades are also installed in the middle section of the horizontal support rods.

[0009] Optionally, the length of the filter box is the same as the width of the inner wall of the distribution box, and the length and width of the drawer are the same as the length and width of the inner wall of the filter box.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this utility model.

[0026] like Figure 1-5As shown, this utility model provides a reaction vessel, including a support 1 and a distribution box 2 disposed below the support 1. The reaction vessel body 3 is installed on the support 1 through a circular hole 10. The bottom of the reaction vessel body 3 has a discharge port 30, which is connected to the inlet 20 on the top of the distribution box 2 through a discharge valve 31. A drain port 33 is also provided on the bottom of one side wall of the distribution box 2. A filter box 4 communicating with the inlet 20 is fixedly installed inside the distribution box 2. At least two drawers 41 are movably installed inside the filter box 4. A handle 42 is installed on the outer side of one side wall of the drawer 41. The drawer 41 is taken out and put in through the slot 43 opened on the distribution box 2 and the filter box 4. After the drawer 41 is closed, the side wall with the handle 42 is flush with the slot 43. Filter holes 44 are provided on the left and right side walls and bottom of the filter box 4 and the drawers 41.

[0027] The reactor includes a support 1, on which a circular hole 10 is provided for mounting the reactor body 3. Installation can be performed using welding, threaded connection, or other connection methods, which are not limited here.

[0028] During operation, the reactants react inside the reactor body 3. After the reaction is complete, the discharge valve 31 is opened, and the material is discharged from the reactor body 3 through the discharge port 30. The material discharged from the discharge port 30 enters the distribution box 2 through the feed port 20 for solid-liquid phase separation.

[0029] The material first falls into the filter box 4 from the distribution box 2, specifically into a drawer 41 located at the top of the filter box 4. A handle 42 is installed on the outer side of one side wall of the drawer 41 for easy access. The side wall of the drawer 41 with the handle 42 is flush with the opening 43 to prevent material leakage. The liquid phase material leaks through the filter holes 44 in the drawer 41 and the filter box 4 into the bottom of the distribution box 2 for collection, while the solid phase material remains on the drawer 41. After the material has been filtered for a period of time, to prevent excessive accumulation in the drawer 41, the upper drawer 41 can be removed to collect the solid phase material. After removing the upper drawer 41, the material discharged from the reactor body 3 falls into the lower drawer 41 for further collection and filtration. After all the solid phase material in the drawer 41 has been collected, it can be reinstalled into the filter box 4. It should be noted that when the drawer 41 is removed to collect the solid material, at least one drawer 41 must be installed in the filter box 4 to prevent the solid phase from falling directly into the filter box 4.

[0030] During the reaction, a portion of the material can be collected by controlling the opening of the discharge valve 31 and separated into solid and liquid components through the distribution box 2, so as to facilitate observation and detection of the reaction state of the material in the reactor.

[0031] The reaction vessel provided by this utility model, through the cooperation between the reaction vessel body 3, the discharge valve 31 and the distribution box 2, allows the material in the reaction vessel to be extracted and separated into solid and liquid at any time during the reaction process or after the reaction is completed. The process is simple, reduces the workload of operators, and improves the efficiency of solid-liquid separation.

[0032] like Figure 3 As shown, a motor 34 is further installed on the top of the reactor body 3. The output end of the motor 34 passes through the top of the reactor body 3 and is connected to the stirring device 35. The top of the reactor body 3 is also provided with a solid material inlet 36 and a liquid material inlet 37.

[0033] The motor 34 at the top of the reactor body 3 drives the stirring device 35 to stir the materials inside the reactor body 3, thereby making the material reaction more complete. The solid material inlet 36 and the liquid material inlet 37 are used for the input of solid and liquid materials, respectively.

[0034] Furthermore, the bottom of the reactor body 3 is an inverted cone-shaped structure, and the discharge port 30 is located at the end of the inverted cone-shaped structure.

[0035] Setting the bottom of the reactor body 3 into an inverted cone shape and setting the discharge port 30 at the bottom of the inverted cone structure helps the material to be discharged from the reactor body 3.

[0036] like Figure 3 As shown, the stirring device 35 further includes a stirring shaft 340 directly connected to the output end of the motor 34. A spiral blade 341 extending into the discharge port 30 is connected to the end of the stirring shaft 340. The blade diameter of the spiral blade 341 is 1 / 3 to 1 / 2 of the inner diameter of the discharge port 30. A horizontal support rod 342 is symmetrically installed along the axial direction on the stirring shaft 340. A straight scraper 343 abutting against the inner wall of the reactor body 3 is connected to the end of the horizontal support rod 342. An inclined support rod 344 is installed below the horizontal support rod 342. An inclined scraper 345 abutting against the inverted conical structure is connected to the end of the inclined support rod 344. A stirring blade 346 is also installed in the middle section of the horizontal support rod 342.

[0037] The stirring shaft 340 is directly connected to the output end of the motor 34, playing a major role in rotation, thereby driving the other components on the stirring device 35 to rotate. The spiral blades 341 have two functions: firstly, during the reaction process, they can overturn the material at the bottom of the reactor body 3, preventing material from accumulating near the discharge port 30, thus improving the material conversion rate. Secondly, since the spiral blades 341 extend into the discharge port 30, they rotate slowly during the discharge of material from the discharge port 30 after the reaction is complete, preventing excessive material from clogging the discharge port 30 and improving the smoothness of the device's operation.

[0038] The straight scraper 343 connected to the end of the horizontal support rod 342 is used to scrape off the material on the inner wall of the reactor body 3 to prevent the material from sticking to the side wall and causing material waste. The inclined scraper 345 connected to the end of the inclined support rod 344 scrapes off the material above the inverted conical structure at the bottom of the reactor body 3. The stirring plate 346 plays the main role in stirring and mixing the materials.

[0039] Through the synergistic effect of the various components in the stirring device 35, the uniformity of material mixing is improved, the contact between reactants is more thorough, and the reaction efficiency and reactant conversion rate are increased.

[0040] like Figure 4 and Figure 5 As shown, further, the length of the filter box 4 is the same as the width of the inner wall of the distribution box 2, and the length and width of the drawer 41 are the same as the length and width of the inner wall of the filter box 4. Further, a slide rail 45 is provided on the side wall of the filter box 4, and a slide groove 46 that cooperates with the slide rail 45 is provided on the side wall of the drawer 41.

[0041] The drawer 41 is installed in conjunction with the filter box 4 via the slide rail 45 and the slide groove 46, making the installation and removal process convenient and quick.

[0042] like Figure 4 and Figure 5 As shown, the side wall of the distribution box 2 is further provided with a filtration port 21, which is connected to the filtration pump 22. Furthermore, the distribution box 2 is also provided with an observation window 23.

[0043] By setting up a filtration port 21 and a filtration pump 22, filtration can be performed during the solid-liquid separation process, thereby improving the efficiency of solid-liquid separation. The observation window 23 facilitates observation of the state in the distribution box 2, making it easier for operators to control the device.

[0044] Furthermore, the inner wall of the reactor body 3 is made of fiberglass.

[0045] The following is the complete usage process of the reaction vessel provided by this utility model:

[0046] The reactants are fed into the reactor body 3 through the solid material inlet 36 and the liquid material inlet 37, respectively, and react inside the reactor body 3. During the reaction, the stirring device 35 driven by the motor 34 stirs the materials inside the reactor body 3. The stirring blades 346 play the main role in stirring the mixture, the straight scraper 343 is used to scrape the material off the inner wall of the reactor body 3 to prevent the material from sticking to the side wall, and the inclined scraper 345 scrapes the material above the inverted conical structure at the bottom of the reactor body 3. The spiral blades 341 tumble the material at the bottom of the reactor body 3 to prevent the material from accumulating near the discharge port 30.

[0047] During or after the reaction, the discharge valve 31 is controlled to discharge the material from the discharge port 30 into the reactor body 3. The material discharged from the discharge port 30 enters the distribution box 2 through the feed port 20 for solid-liquid phase separation.

[0048] The material first falls into the filter box 4 from the distribution box 2, specifically into a drawer 41 located at the top of the filter box 4. A handle 42 is installed on the outer side of one side wall of the drawer 41 for easy access. The side wall of the drawer 41 with the handle 42 is flush with the opening 43 to prevent material leakage. The liquid phase material leaks through the filter holes 44 in the drawer 41 and the filter box 4 into the bottom of the distribution box 2 for collection, while the solid phase material remains on the drawer 41. After filtration for a period of time, to prevent excessive accumulation of material in the drawer 41, the upper drawer 41 can be removed to collect the solid phase material. After removing the upper drawer 41, the material discharged from the reactor body 3 falls into the lower drawer 41 for further collection and filtration. After all the solid phase material in the drawer 41 has been collected, it can be reinstalled into the filter box 4. During the solid-liquid separation process, to improve efficiency, a vacuum filtration pump 22 can also be activated for vacuum filtration. During the process of material discharge from the reactor body 3, the spiral vane 341 rotates slowly to prevent excessive material from clogging the discharge port 30. The observation window 23 facilitates observation of the status in the distribution box 2 and allows operators to control the device.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
