[0002] In fields such as petrochemicals, fine chemicals, pharmaceutical manufacturing, and specialty materials, reaction synthesis, washing, and filtration processes are common. These operations must be performed in a sealed environment protected by a special atmosphere. Furthermore, reaction, filtration, and washing must be performed in the same facility, requiring specialized equipment. Furthermore, since product preparation reactions generate numerous reaction byproducts, large quantities of solvents are required as washing fluids to produce qualified products. Some specialized products even have small reaction product particles that are difficult to separate during the washing process.

[0003] Due to the particularity of the above-mentioned production process, liquid-solid separation needs to be carried out in a closed environment protected by a special atmosphere. Currently, most traditional reactors use gravity sedimentation to separate liquids and solids. However, this sedimentation method takes a long time to separate liquids and solids, and has low separation efficiency. Especially during the washing process, when a large amount of washing liquid is used, the number of washing times is high, and the product particle size is small, the traditional gravity sedimentation method takes several days to separate, resulting in very low production efficiency of the entire product production line.

[0004] Therefore, it is particularly important to design a three-in-one reaction washing and filtering equipment to improve the washing and filtering effect and speed. Utility Model Content

[0034] refer to Figure 1 As shown, the three-in-one reaction washing and filtration equipment includes:

[0035] Reaction vessel 1;

[0036] The filter element 2 is disposed in the reaction vessel 1 and divides the inner cavity of the reaction vessel 1 into a reaction cavity 201 and a main filter cavity 205 . The filter element 2 is configured to allow the flow of filtrate and gas.

[0037] A pressure control unit 3 is provided on the upper portion of the reaction vessel 1 to adjust the pressure in the reaction vessel 1;

[0038] The material conveying unit includes a feeding assembly 4 and a discharging assembly 5. The feeding assembly 4 is arranged at the top of the reaction vessel 1 and is used to convey the material or washing solvent into the reaction vessel 1. The discharging assembly 5 is arranged at the bottom of the reaction vessel 1 and is used to discharge the washed material from the reaction vessel 1. Both the feeding assembly 4 and the discharging assembly 5 are in communication with the reaction chamber 201.

[0039] The drainage mechanism 6 is communicated with the main filter chamber 205 and is used to discharge the filtrate in the main filter chamber 205.

[0040] The feeding component 4 can also deliver the reacted material into the reaction container 1 .

[0041] Through the above technical solution, the feed component in the three-in-one reaction washing and filtering equipment provided by the present invention inputs the material into the reaction chamber 201 of the reaction vessel 1, and fills the gas through the pressure control unit 3 to increase the pressure in the reaction vessel 1, thereby accelerating the liquid in the material to pass through the filtering component into the total filter chamber 205, and the filtrate is discharged from the total filter chamber 205 in time through the drainage mechanism 6. Therefore, the problems of long liquid-solid separation time and low separation efficiency of the sedimentation method are avoided, and the production efficiency of the entire product production line is improved.

[0042] The filter element 2 in the present invention can be any suitable structure, such as Figure 1 In the illustrated embodiment, the filter element 2 may include a filter screen 204 , which may be disposed along the inner wall of the reaction vessel 1 to increase the filtering area and improve the filtering efficiency.

[0043] The filter screen 204 and the inner wall form a main filter cavity 205 , and a support structure may be provided in the main filter cavity 205 for supporting the filter screen 204 to ensure that the filter screen 204 will not be damaged due to the pressure increase in the reaction container 1 .

[0044] In which, filter holes can be set on the filter mesh 204 as a filter channel connecting the reaction chamber 201 and the main filter chamber 205, and the size of the filter holes can be smaller than the size of the solid particles placed in the reaction chamber 201, so that the filter holes can allow filtrate and gas to flow.

[0045] In addition, the present invention can increase the height of the filter screen 204 so that the filter screen 204 and the inner wall of the lower part and the side of the entire reaction container 1 form a total filter cavity 205 to increase the filtering area.

[0046] The filtration area of ​​the filter screen 204 arranged in the above manner is several dozen times greater than that of the conventional reaction vessel 1 . Therefore, the filtration efficiency of the present invention is faster and the production efficiency is higher.

[0047] The support structure in the present invention can have any appropriate structure, such as Figure 1 In the illustrated embodiment, the support structure includes a plurality of partitions 203 arranged in parallel and at equal intervals along the height direction of the reaction container 1 .

[0048] Among them, one end of each partition 203 can be fixedly connected to the filter screen 204, and the other end can be fixedly connected to the inner wall of the reaction vessel 1 to provide support force to the filter screen 204. Multiple partitions 203 can divide the total filter chamber 205 into multiple sub-filter chambers 202 horizontally and layeredly. Each sub-filter chamber 202 can be connected to the drainage mechanism 6 to timely discharge the filtrate in the sub-filter chamber 202, thereby improving work efficiency.

[0049] In some embodiments, the multiple sub-filter chambers 202 may not be connected to each other. The drainage mechanism 6 includes a main drainage pipe 601 and multiple drainage branches 602 respectively connected to the main drainage pipe 601. The multiple drainage branches 602 are connected to the multiple sub-filter chambers 202 one by one. Each drainage branch pipe 602 is provided with a first liquid valve 603 to control its on and off.

[0050] The main drain pipe 601 may be provided with a second liquid valve 604 for controlling the on / off of the main drain pipe 601 .

[0051] In the present invention, as the solution in the reaction chamber 201 gradually decreases and the connection between the filter chamber and the drainage branch pipe 602 cannot be immersed, the first liquid valve 603 on the drainage branch pipe 602 is closed from top to bottom along the height direction of the reaction container 1 according to the page height of the filtrate in the reaction container 1, preventing the gas in the reaction container 1 from being discharged from the drainage branch pipe 602, ensuring that the gas pressure in the reaction container 1 does not decrease and the filtration speed of the filtrate will not decrease, thereby achieving the purpose of rapid filtration.

[0052] Among them, because each sub-filter chamber 202 is different from each other, after closing the first liquid valve 603 on the drainage branch 602 in the sub-filter chamber 202 located in the upper part of the reaction vessel 1, it is avoided that gas flows through the sub-filter chamber 202 to the sub-filter chamber 202 below that also contains filtrate, and flows out of the reaction vessel 1 through the drainage branch 602 in the sub-filter chamber 202 below, thereby ensuring the pressure stability in the reaction vessel 1.

[0053] In addition, the blockage of some filtrate channels on the filter screen 204, which causes the pressure in one or more sub-filter chambers 202 to be too low, is also avoided. The filtrate in other sub-filter chambers 202 flows to the sub-filter chamber 202 with too low pressure under the action of the pressure in the reaction chamber 201, and the gas will flow along with the filtrate. Since the filtrate cannot immerse the connection between the drainage branch pipe 602 and the filtrate during the flow process, gas leakage will occur.

[0054] Of course, in other embodiments, multiple sub-filter chambers 202 can be connected. It is worth noting that at this time, the drainage branch pipe 602 of the drainage mechanism 6 can be connected to the lowest point of the main filter chamber 205, so that the filtrate in the sub-filter chamber 202 is always immersed in the connection between the drainage branch pipe 602 and the main filter chamber 205, avoiding the above-mentioned air leakage.

[0055] In some embodiments, the three-in-one reaction washing and filtering equipment may further include a cleaning component 8, one end of which is connected to the medium source, and the other end is connected to the drainage mechanism 6 for timely backflushing and cleaning the clogged filter channel on the filter element 2.

[0056] The cleaning assembly 8 in the present invention can have any suitable structure, such as Figure 2 In the embodiment shown, the cleaning assembly 8 may include a delivery pipe 801, one end of which is connected to the medium source, and the other end is connected to the drainage mechanism 6, thereby communicating with each sub-filtration chamber 202, and each delivery pipe 801 is provided with a control valve 802 for controlling its on and off.

[0057] Of course, in some other embodiments, the cleaning component 8 may include multiple delivery pipes 801, each delivery pipe 801 is connected to multiple sub-filter chambers 202 one by one, and a control valve 802 may be provided on each delivery pipe 801 to control the on and off of the delivery pipe 801; a delivery main pipe 301 may also be provided, and multiple delivery branches are provided at the tail end of the delivery main pipe 301, and a main control valve 802 is provided on the delivery main pipe 301.

[0058] It is understandable that the structure of the cleaning component 8 in this embodiment is complex, and the three-in-one reaction washing and filtering equipment has a higher space requirement for the production site, which increases the production cost.

[0059] like Figure 1 As shown, when cleaning the clogged filter holes on the filter screen 204, after stopping filtration, first disconnect the drainage main pipe 601 from the drainage branch pipes 602, then open the control valve 802, connect the delivery pipe 801 with the drainage branch pipes 602, and use the delivery pipe 801 to deliver the medium into each sub-filter cavity 202 to reversely purge the filter screen 204 to clear the clogged filter holes on the filter screen 204.

[0060] Among them, because the multiple sub-filter chambers 202 set up in the utility model are not connected to each other, when backflushing into the sub-filter chamber 202 for cleaning, it is avoided that after other sub-filter chambers 202 are dredged, the medium in the undredged sub-filter chamber 202 flows into the dredged sub-filter chamber 202, thereby improving the dredging rate.

[0061] Among them, the utility model regularly starts the cleaning component 8, which can clean the blocked filter channel of the filter component in time and maintain a good filtering effect, thereby increasing the washing and filtering speed and improving the product production efficiency.

[0062] In addition, the medium source may include any one or a combination of more than one of nitrogen, helium, organic solvent and water.

[0063] In some embodiments, the three-in-one reaction washing and filtering equipment may include a stirring mechanism 7 for scraping off the filter cake formed on the filter screen 204 to prevent the filter cake from being too thick and obstructing the flow channel of the filtrate in the filter component, thereby increasing the washing and filtering speed and improving product production efficiency.

[0064] The stirring mechanism 7 in the present invention can have any appropriate structure, such as Figure 3 In the embodiment shown, the stirring mechanism 7 may include a motor 701, a stirring shaft 702, a seal and a scraper. The motor 701 may be arranged at the top of the reaction vessel 1, and the output end of the motor 701 is connected to the stirring shaft 702. The stirring shaft 702 passes through the reaction vessel 1 and is connected to the scraper located in the reaction vessel 1.

[0065] Among them, the motor 701 drives the stirring shaft 702 to rotate, thereby driving the scraper to rotate to scrape off the filter cake formed on the filter screen 204. It can also be used to stir the material in the reaction vessel 1. The seal is provided at the connection between the stirring shaft 702 and the reaction vessel 1 to prevent the gas in the reaction vessel 1 from flowing out from the connection.

[0066] In addition, the stirring mechanism 7 may also include a reducer and a frequency converter. The reducer is used to reduce the speed of the motor 701 while increasing the torque output by the motor 701. The frequency converter is used to control the speed and torque of the motor 701 to provide smooth starting and stopping, thereby reducing the energy consumption of the stirring mechanism 7.

[0067] In some embodiments, the scraper may include a frame-type scraper 703, the shape of the frame-type scraper 703 matches the shape of the side of the filter screen 204 close to the reaction chamber 201, so as to better scrape the filter cake formed on the filter element 2; of course, in other embodiments, other styles of scrapers or scrapers may be selected, and the present invention will not be described in detail here.

[0068] In some embodiments, the height of the frame scraper 703 is the same as that of the filter element 2 and is as close to the filter element 2 as possible so as to be able to scrape off the filter cake formed on the entire filter element 2 .

[0069] The optimal distance between the frame scraper 703 and the filter element 2 is 10-100 mm.

[0070] In some embodiments, a medium cavity 9 may be provided on the outer wall of the reaction vessel 1, and a medium is introduced into the medium cavity 9 to heat or cool the reaction vessel 1 at the temperature of the medium to provide ambient temperature conditions for the reaction carried out in the reaction vessel 1; the washed material in the reaction vessel 1 may also be dried.

[0071] The medium cavity 9 may extend from the bottom of the reaction vessel 1 along its outer wall to the upper portion of the reaction vessel 1 to maximize the contact area between the medium in the medium cavity 9 and the outer wall of the reaction vessel 1 , thereby improving the heating efficiency of the reaction vessel 1 by the medium.

[0072] Of course, in other embodiments, other structures capable of generating heat or cooling may be provided on the outer wall of the reaction vessel 1; or the gas delivered to the reaction vessel 1 by the pressure delivery unit may be heated or cooled to change the temperature environment inside the reaction vessel 1, thereby meeting the reaction requirements for the ambient temperature. It is worth noting that at this time, the drainage mechanism 6 may be opened to maintain the pressure inside the reaction vessel 1 stable.

[0073] The liquid discharge mechanism 6 and / or the pressure control unit 3 may be used to discharge the gas generated by the reaction out of the reaction chamber 201 .

[0074] Among them, a medium input pipe 901 is provided at the bottom of the medium chamber 9 near one end of the unloading assembly 5, and the other end of the medium input pipe 901 is connected to an external medium conveying device for conveying the medium into the medium chamber 9. A medium output pipe 902 is provided on the side of the medium chamber 9 near the top of the reaction vessel 1, and the other end of the medium output pipe 902 is connected to an external medium extraction device for discharging the medium in the medium chamber 9.

[0076] In some embodiments, the drainage branch pipe 602 may pass through the medium cavity 9 and be connected to the sub-filtration cavity 202 , and the connection between the drainage branch pipe 602 and the medium cavity 9 is sealed to prevent the medium from overflowing from the connection.

[0077] In some embodiments, the outer wall of the medium cavity 9 may be made of thermal insulation material to reduce the heat exchange between the medium and the outside world.

[0078] The pressure delivery unit in the present invention can have any structure, such as Figure 1 In the embodiment shown, the pressure control unit 3 includes a pressure indicator 304 and a manifold 301. The pressure indicator 304 is arranged on the top of the reaction vessel 1 and is used to measure the pressure in the reaction vessel 1 to monitor the pressure value in the reaction vessel 1 in real time.

[0079] In some embodiments, one end of the main pipe 301 is connected to the reaction chamber 201, and the other end is connected to two branch pipes 302. Each branch pipe 302 can inflate and pressurize or exhaust and reduce the pressure in the reaction container 1 through the main pipe 301; of course, in other embodiments, any other number of branch pipes 302 can be set, and some of the branch pipes 302 can be set to inflate and pressurize, and other part of the branch pipes 302 can be set to exhaust and reduce the pressure.

It is worth noting that at this time, the intake or exhaust status of all branch pipes 302 must be the same.

[0081] The gas inputted into the reaction container 1 by the pressure control unit 3 may include nitrogen or helium; or gases participating in the reaction may be introduced into the reaction container 1 during the reaction.
