Description

Technical Field

[0001] The present application relates to the technical field of chemical production, and in particular to a high-pressure atomization liquid supply structure. Background Art

[0002] In the chemical production process, in order to avoid insufficient reaction in various places in the reactor due to excessive concentration of liquid materials in the reactor after being added to the reactor, it is necessary to use atomization to supply liquid to add liquid materials into the reactor. At present, when adding liquid materials into the reactor by atomization, the main method is to extend the atomizing nozzle into the reactor body, and then pressurize the liquid material in the storage container to add the liquid material to the reactor body. For example, a spray-feeding reactor disclosed in patent document No. CN201520070727.7 and a sealed reactor atomization feeding device disclosed in patent document No. CN202120021763.X both use the above method to add liquid materials to the reactor.

[0003] The existing high-pressure atomizing liquid supply structure is prone to blockage of the liquid supply pipeline due to the presence of impurities in the liquid material during the atomizing liquid supply process, thereby causing the high-pressure atomizing liquid supply to be not smooth enough and the liquid supply efficiency to be relatively low in the chemical production process; some existing solutions adopt the form of removing and replacing or cleaning the filter to dredge it, but the cleaning requires shutdown and disassembly of the sealing shell such as the connecting nut, which consumes a lot of time. Some equipment uses backwashing to clean the filter and then reuse it, but this cleaning process also needs to be carried out in the shutdown state, which will also affect the actual production use. In order to solve the problem of not stopping the filter element or shortening the cleaning time, a high-pressure atomizing liquid supply structure is proposed. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present application is to provide a high-pressure atomization liquid supply structure that can achieve efficient removal of impurities from the filter element in the chemical production process through alternating filtration, and can automatically flush the double-sided filter screens by alternating flushing, thereby achieving short-term or no-stop shutdown and filter cleaning.

[0005] The above application objectives of this application are achieved through the following technical solutions:

[0006] A high-pressure atomization liquid supply structure comprises a material storage box, two fixed plates are installed in parallel on the material discharge side of the material storage box, a filter box is installed on the two fixed plates facing away from the material storage box, two storage sleeves are symmetrically installed in the middle of the two long side walls of the filter box, an alternating filter mechanism is installed between the filter box and the storage sleeve, the alternating filter mechanism comprises a screw, a linkage rod, a driving motor, a gear 1, a gear 2, a support plate, a sealing edge and a double-sided filter screen plate, wherein two support plates are symmetrically installed on both sides of the top of the filter box, a screw is rotatably installed between the two support plates, and the The two ends of the screw are respectively connected with the linkage rod, and the linkage rod consists of two, and the two linkage rods are respectively connected to the two ends of the double-sided filter screen plates, and the double-sided filter screen plates are slidably installed in the filter box and the storage sleeve, the gear 2 is located in the middle of the screw, the gear 1 is located on the lower side of the gear 2, the power input end of the gear 1 is connected to the drive motor, the sealing edge is installed on the two filter surface ends of the double-sided filter screen plates, and a flushing mechanism is also installed between the storage sleeve and the storage box, and the flushing mechanism includes a water storage tank, a flushing pump, a five-way pipe and a U-shaped spray hood.

[0007] Optionally, the double-sided filter screen plate has two filter surfaces, and the area of ​​each filter surface on the double-sided filter screen plate is the same as the vertical cross-sectional area inside the filter box.

[0008] By adopting the above technical solution, the filtering surfaces on the double-sided filter screen plates are specifically a mesh structure, so that impurities in the liquid material can be filtered through the filtering surfaces on the double-sided filter screen plates. When one filtering surface on the double-sided filter screen plates is located inside the filter box, the other filtering surface is located in one of the storage sleeves. In this way, after the filtering surfaces on the double-sided filter screen plates are adjusted after use, the double-sided filter screen plates can be aligned with the vertical area of ​​the filter box, so that the filter box can continue to be used for filtering, and the stability of the double-sided filter plates after installation in the filter box can be ensured.

[0009] Optionally, the screw rod is threadedly connected to the two linkage rods, and the portion on the side wall of the filter box that cooperates with the double-sided filter screen plates is a hollow structure.

[0010] By adopting the above technical solution, the linkage rod is specifically an L-shaped bending structure, and when the screw rod rotates, the linkage rod can be conveniently moved and adjusted along the length direction of the screw rod under the action of thread transmission.

[0011] Optionally, the U-shaped spray hood is nested in the inner wall of the storage sleeve.

[0012] Optionally, the U-shaped spray hood has two independent spray chambers, and the spray holes at each spray chamber of the U-shaped spray hood face the interior of the receiving sleeve.

[0013] By adopting the above-mentioned technical scheme, the U-shaped spray hood is embedded in the inner wall of the storage sleeve, so that a continuous and flat guide rail and plane can be formed inside the filter box and the storage sleeve, thereby preventing the U-shaped spray hood from being obstructed when the filter screen plates on both sides move, ensuring that the edges between the two are flush during the position adjustment process, and facilitating smooth movement. The sealing edge set during movement can achieve sealing to avoid leakage. The edge of the sealing plate is made of rubber material, which can maintain a certain elastic force to prevent liquid leakage.

[0014] In order to reduce the occurrence of leakage during cleaning, the machine can be stopped for a short time to move the filter plates on both sides. After moving, the machine can be started and used without waiting until the filter is completely cleaned. This form is relatively shorter than the existing shutdown flushing and better reduces the impact on continuous work.

[0015] When in use, the cleaning water in the water storage tank is pumped into the U-shaped spray hood by the flushing pump, so that the used filter surfaces on the double-sided filter screens can be flushed through the U-shaped spray hood in a single-sided or double-sided spraying manner.

[0016] By adopting the above technical solution, the U-shaped spray hood is embedded in the inner wall of the storage sleeve, which can avoid the U-shaped spray hood from hindering the movement of the double-sided filter screen plates.

[0017] Optionally, the five-way pipe is connected to the flushing pump and the U-shaped spray hood via flanges, and each independent spray chamber in the U-shaped spray hood on the five-way pipe is provided with a valve at the pipeline connected to the independent spray chamber in the U-shaped spray hood, thereby enabling the independent spray chamber in the U-shaped spray hood to achieve single-sided or double-sided spray effects.

[0018] By adopting the above technical solution, the five-way pipe can realize that the cleaning water pumped by the flushing pump can be delivered to the corresponding U-shaped spray hood as needed, and the valve is the main component for controlling the flow direction of water in the five-way pipe. The valve is used to control the water to be delivered to the corresponding independent spray chamber in the U-shaped spray hood to realize the water spraying function of the U-shaped spray hood.

[0019] Optionally, the discharge port of the filter box is also connected to a feed pipe, the discharge port of the feed pipe is connected to an atomizing nozzle, and a high-pressure pump is installed on the storage box at the lower side of the filter box.

[0020] By adopting the above technical solution, the high-pressure pump, the feed pipe and the atomizing nozzle share a common atomizing liquid supply mechanism. During liquid supply, the high-pressure pump is used to spray the liquid material in the storage box into the reactor body through the feed pipe and the atomizing nozzle.

[0021] Optionally, a feeding pipe is also installed on one side of the top of the storage box, and a mixing mechanism is also installed on the storage box, the mixing mechanism includes a mixing motor and a mixing rack, wherein the mixing rack is located in the middle of the top of the storage box, and the mixing rack is rotatably installed in the middle of the storage box.

[0022] By adopting the above technical solution, liquid material can be conveniently added to the storage box through the feeding pipe. Before high-pressure atomization liquid supply, the mixing motor drives the mixing rack to rotate, so as to achieve sufficient stirring of the liquid material in the storage box to avoid precipitation during the storage of the liquid material.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] The utility model installs an alternating filtering mechanism consisting of a screw rod, a linkage rod, a driving motor, a gear 1, a gear 2, a support plate and double-sided filter screen plates on the filter box at the material discharge side of the storage box. When atomizing and supplying liquid to the reactor body in the chemical production process, the filter surfaces on the double-sided filter layer screen plates are alternately located in the middle of the filter box, thereby achieving effective removal of impurities in the liquid material during the atomizing and supplying process, avoiding the drawback that the liquid supply pipeline is blocked due to the presence of impurities in the liquid material during the atomizing and supplying process, ensuring the smoothness of the entire atomizing and supplying process, and improving the atomizing and supplying efficiency in the chemical production process.

[0025] The utility model symmetrically installs two storage sleeves on both sides of the filter box, and jointly installs a flushing mechanism composed of a water storage tank, a flushing pump, a five-way pipe and a U-shaped spray cover between the storage sleeve and the storage box. When the filter surfaces of the double-sided filter screen plates after use are located in the corresponding storage sleeves, the flushing pump can be used to spray water in the water storage tank through the feed pipe and the U-shaped spray cover onto the filter surfaces of the double-sided filter screen plates after use, thereby realizing automatic flushing of the single-sided or double-sided filter surfaces of the double-sided filter screen plates after use, thereby ensuring the rapid cleaning and use of the double-sided filter screen plates.

[0026] The utility model installs an alternating filter mechanism with double-station filtering on the filter box, and installs flushing mechanisms for cleaning the filter surface on the alternating filter mechanism on both sides of the filter box. When atomizing liquid into the reactor body in the chemical production process, the double-sided filter screen plates on the alternating filter mechanism can be adjusted in position by briefly stopping the device or not stopping the device, ensuring that when the filter surface of the alternating filter mechanism is cleaned after use, the other clean filter surface of the alternating filter mechanism can continue to be used for liquid supply, thereby reducing the downtime of the device when cleaning the filter screen surface, thereby making the entire liquid supply process of the device more continuous.

[0035] The present application is further described in detail below in conjunction with the accompanying drawings.

[0036] In order to more clearly understand the technical solutions presented in the embodiments of the present application, the existing high-pressure atomization liquid supply method in the chemical production process is first introduced.

[0037] At present, when adding liquid materials into the reactor by atomizing liquid supply, the liquid materials are mainly added into the reactor body by extending an atomizing nozzle into the reactor body and then pressurizing the liquid materials in the storage container.

[0038] See also Figures 1 to 7, is a high-pressure atomization liquid supply structure disclosed in an embodiment of the present application, including a storage box 11, two fixed plates 12 are installed in parallel on the discharge side of the storage box 11, and a filter box 7 is installed on the two fixed plates 12 facing away from the storage box 11. Two storage sleeves 8 are symmetrically installed in the middle of the two long side walls of the filter box 7, and an alternating filter mechanism 6 is installed between the filter box 7 and the storage sleeve 8. The alternating filter mechanism 6 includes a screw 61, a linkage rod 62, a drive motor 63, a gear 1 64, a gear 2 65, a support plate 66, a sealing edge 68 and a double-sided filter screen plate 67, wherein two support plates 66 are symmetrically installed on both sides of the top of the filter box 7, a screw 61 is rotatably installed between the two support plates 66, and both ends of the screw 61 They are respectively connected with linkage rods 62, and the linkage rods 62 consist of two, and the two linkage rods 62 are respectively connected to the two ends of the bilateral filter screen plates 67, and the bilateral filter screen plates 67 are slidably installed in the filter box 7 and the storage sleeve 8. Gear 2 65 is located in the middle of the screw 61, and gear 1 64 is located on the lower side of gear 2 65. The power input end of gear 1 64 is connected to the drive motor 63, and the sealing edge 68 is installed at the two filter surface ends of the bilateral filter screen plates 67. A flushing mechanism 5 is also installed between the storage sleeve 8 and the storage box 11. The flushing mechanism 5 includes a water storage tank 51, a flushing pump 52, a five-way pipe 53 and a U-shaped spray cover 54. The storage sleeve 8 also has a drainage pipe in the middle of the bottom end, which can facilitate the convenient discharge of waste liquid after flushing.

[0039] Specifically, in the chemical production process, liquid is supplied to the reactor body in a high-pressure atomization manner. First, the gear 1 64 is rotated under the action of the driving motor 63. After the gear 1 64 rotates, the screw 61 is rotated under the action of the gear 2 65. After the screw 61 rotates, it cooperates with the linkage rod 62 under the action of the threaded transmission to adjust the filtering surface on the double-sided filter screen plates 67 to the filter box 7, so that the liquid in the liquid supply process can be filtered under the action of the filtering surface of the double-sided filter screen plates 67 to prevent the liquid material from clogging the liquid supply pipeline during the transportation process.

[0040] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 The double-sided filter mesh plate 67 has two filter surfaces, and the area of ​​each filter surface on the double-sided filter mesh plate 67 is the same as the vertical cross-sectional area inside the filter box 7 , and the sealing edge 68 is installed at the two filter surface ends of the double-sided filter mesh plate 67 .

[0041] As an implementation method, two filter surfaces are designed on the double-sided filter screen plate 67. When one filter surface is blocked and needs to be cleaned, the other unused filter surface on the double-sided filter screen plate 67 can be adjusted by sliding to face the part inside the filter box 7 for liquid circulation, thereby ensuring continuous filtration of the liquid during high-pressure atomization liquid supply. When replacing the filter surfaces on the double-sided filter screen plate 67, the liquid material can be non-transported, or continuous transportation can be achieved. Continuous transportation is achieved by the edge of the sealing edge 68 cooperating with the inner wall of the filter box 7 and the storage sleeve 8 to achieve airtightness during movement, thereby achieving no leakage.

[0042] See also Figure 1 , Figure 3 , Figure 5 and Figure 7 The screw rod 61 and the two linkage rods 62 are both threadedly connected, and the portion on the side wall of the filter box 7 that cooperates with the double-sided filter screen plates 67 is a hollow structure.

[0043] As an implementation mode, both ends of the screw rod 61 are provided with threads, and under the action of the threads at both ends of the screw rod 61, the two linkage rods 62 can be synchronously moved along the axial direction of the screw rod 61 to achieve stable sliding adjustment of the double-sided filter screen plates 67; and the hollow portion on the side wall of the filter box 7, on the one hand, is to facilitate the convenient sliding of the double-sided filter screen plates 67 relative to the filter box 7 during sliding adjustment, and on the other hand, is to ensure that the filter surfaces on the double-sided filter screen plates 67 can be blocked at the middle structure of the side wall of the filter box 7 under the action of the baffle plates provided at the ends of the double-sided filter screen plates 67 after extending into the filter box 7, so as to ensure that the liquid material is filtered out of the filter box 7. The high-pressure pump 9 can also choose to stop working or continuously perform two working conditions according to the needs. That is to say, during the process of adjusting the double-sided filter screen plates 67, there will be no leakage of liquid material in the filter box 7. After the adjustment, the sealing edges 68 on the double-sided filter screen plates 67 are used to block and seal the hollow parts of the filter box 7, which can ensure the normal filtering sealing of the filter box 7 when the double-sided filter screen plates 67 are adjusted, and avoid the leakage and reflux of liquid material after the adjustment process and the cleaning process are carried out simultaneously.

[0044] In some special cases such as when the production task is urgent, the double-sided filter screen plates 67 will be cleaned without stopping the machine. In this case, a certain amount of supply liquid will be lost, but the volume of liquid discharged with the waste liquid is smaller than the volume of the internal cavity of the storage sleeve 8 (the double-sided filter screen plates 67 on the cleaning side also occupy a certain volume). However, the lost liquid volume is small and the impact on production can be ignored. This is because when the edge of the double-sided filter screen plates 67 moves away from the edge of the filter box 7 during the movement, the liquid on one side will pass through the gap between the double-sided filter screen plates 67 and the filter box 7 that are not aligned and enter the storage sleeve 8 on the side to be cleaned. A pipeline is provided at the end, and a valve body is provided on the pipeline. It will not be connected to the outside when it is not cleaned. When the storage sleeve 8 is full, the internal liquid will not be continuously discharged to the outside, and the dirty liquid will be discharged along with the cleaning when it reaches the cleaning position. In actual use, the waste liquid after cleaning will be concentrated in the existing sewage treatment equipment in the workshop for subsequent treatment, and when the double-sided filter screen plate 67 is moved, the liquid entering through the gap on the other side will follow the movement into the filter box 7 and be used normally. Compared with the existing forms of disassembling bolts and cleaning after shutdown, the material loss generated by this form of cleaning is relatively small, which belongs to the normal loss range in production and will not affect the overall production.

[0045] In actual use, it can be used flexibly by short-term shutdown or no shutdown. Compared with similar equipment with cleaning function, it greatly shortens the time consumed in cleaning blockage, improves the efficiency of workshop production, and meets the needs of actual scenarios.

[0046] See also Figure 1 , Figure 2 and Figure 4 A flushing mechanism 5 is also installed between the storage sleeve 8 and the storage box 11 , and the flushing mechanism 5 includes a water storage tank 51 , a flushing pump 52 , a five-way pipe 53 and a U-shaped spray cover 54 .

[0047] As an implementation method, when the filtering surface used on the double-sided filter screen plates 67 is located in the storage sleeve 8, the cleaning water in the water storage tank 51 can be sprayed onto the used filtering surface of the double-sided filter screen plates 67 through the five-way pipe 53 and the U-shaped spray cover 54 in a single-sided or single-sided spray manner through the flushing pump 52, thereby flushing the double-sided filter screen plates 67. The storage sleeve 8 also has a drain pipe in the middle of the bottom end, which can facilitate the convenient discharge of waste liquid after flushing. A support leg 10 is provided at the lower end of the storage box 11, and the support leg 10 can firmly support the storage box 11 at a certain height, so that it is convenient to use at different heights.

[0048] See also Figure 1 , Figure 4 and Figure 6The U-shaped spray hood 54 is embedded in the inner wall of the storage sleeve 8, and the spray hole of the U-shaped spray hood 54 faces the inside of the storage sleeve 8.

[0049] As an implementation method, the flushing water can be sprayed onto the corresponding filter surfaces on the double-sided filter screen plates 67 through the spray holes on the U-shaped spray cover 54 to flush the rear filter surfaces on the double-sided filter screen plates 67.

[0050] See also Figure 1 and Figure 4 The five-way pipe 53 is connected to the flushing pump 52 and the U-shaped spray hood 54 through flanges. The two sides of each U-shaped spray hood 54 at the end of the five-way pipe 53 are divided into two chambers, namely: each independent spray chamber in the U-shaped spray hood 54 is respectively connected to one of the branches of the five-way pipe 53, and each connected branch pipeline has its own valve. When in use, one side or all of them can be opened as needed, thereby realizing the function of single-sided flushing or double-sided cleaning at the same time. The valve can be opened and closed according to the actual scene requirements.

[0051] As an implementation method, by controlling the opening and closing of the corresponding valve on the five-way pipe 53, the flushing pump 52 can be controlled to conveniently supply water to the corresponding independent spray chamber in the corresponding U-shaped spray hood 54, ensuring that water is supplied from one side or both sides of the U-shaped spray hood 54 and sprayed onto one side or both sides of the double-sided filter screen plate 67, thereby achieving different working conditions of cleaning requirements such as single-sided high pressure or double-sided high flow, with good flexibility in use and improved cleaning effect.

[0052] See also Figure 1 and Figure 2 The discharge port of the filter box 7 is also connected to the feed pipe 2, the discharge port of the feed pipe 2 is connected to the atomizing nozzle 1, and a high-pressure pump 9 is installed on the storage box 11 at the lower side of the filter box 7.

[0053] As an implementation mode, during high-pressure atomization liquid supply, the filtered liquid material will be transported to the atomizing nozzle 1 through the feed pipe 2, so that the liquid material can be atomized by the atomizing nozzle 1 and then sprayed into the reactor body, thereby realizing the atomization feeding of the liquid material.

[0054] See also Figure 1 and Figure 2 A feeding pipe 3 is also installed on one side of the top of the storage box 11, and a mixing mechanism 4 is also installed on the storage box 11. The mixing mechanism 4 includes a mixing motor 41 and a mixing rack 42, wherein the mixing rack 42 is located in the middle of the top of the storage box 11, and the mixing rack 42 is rotatably installed in the middle of the storage box 11.

[0055] As an implementation mode, liquid material can be conveniently added to the storage box 11 through the feeding pipe 3. Before the high-pressure atomization liquid supply, the mixing rack 42 is driven to rotate under the action of the mixing motor 41, so as to achieve sufficient stirring of the liquid material in the storage box 11 to avoid precipitation of the liquid material during storage.

[0056] The specific working principle is that when adding materials to the reactor body in the chemical production process by means of high-pressure atomization liquid supply, the mixing motor 41 is first started. After the mixing motor 41 is started, the mixing frame 42 is driven to rotate, so that the liquid material in the storage box 11 is stirred and mixed under the action of the mixing frame 42, and the mixed material is pumped into the filter box 7 through the high-pressure pump 9, so that the impurities in the liquid material are filtered when the liquid material flows through the filter box 7, and the filtered liquid material enters the atomizing nozzle 1 through the feeding pipe 2, so that the liquid material is sprayed into the reactor body in the form of high-pressure atomization under the action of the atomizing nozzle 1. Under the action of the double-sided filter screen plates 67, the impurities in the liquid material in the atomization liquid supply process are effectively removed, avoiding the disadvantage of the liquid supply pipeline being blocked by the impurities in the liquid material in the atomization liquid supply process, ensuring the smoothness of the entire atomization liquid supply process, thereby improving the atomization liquid supply efficiency in the chemical production process. At the same time, when a filter surface on the double-sided filter screen plates 67 is blocked and needs to be cleaned, the gear 1 64 is rotated under the action of the driving motor 63. After the gear 1 64 rotates, it will rotate the screw 61 through the gear 2 65. After the screw 61 rotates, it will drive the linkage rod 62 to move under the action of the threaded transmission, so that the double-sided filter screen plates can be moved with the help of the linkage rod 62. The used filter surface on 67 is moved to a storage sleeve 8, while the unused filter surface on the double-sided filter screen plates 67 is located inside the filter box 7. The sealing edge 68 provided during the movement can provide a good guarantee for the sealing of the double-sided filter screen plates 67 during the movement, thereby avoiding leakage at the edge of the filter box 7 or the storage sleeve 8 during the movement. The used filter surface of the double-sided filter screen plates 67 will be sprayed with the cleaning water in the water storage tank 51 through the five-way pipe 53 and the U-shaped spray cover 54 onto the used filter surface of the double-sided filter screen plates 67 under the action of the flushing pump 52, thereby realizing the cleaning of the used filter surface of the double-sided filter screen plates 67. When washing, by closing one side of the valve or opening both valves, high-pressure single-sided flushing can be achieved, and high-flow double-sided simultaneous cleaning can also be achieved, which meets the flexible use of different usage scenarios and ensures the continuous use of the double-sided filter screen plates 67. The waste liquid after flushing is discharged through the drain pipe at the bottom of the storage sleeve 8 without affecting the internal liquid supply. It should be noted that when cleaning is completed, the water used by the double-sided filter screen plates 67 adheres to the double-sided filter screen plates 67 and does not dilute the liquid transmitted by the high-pressure pump 9. Generally, the freshly cleaned side will not be used immediately after cleaning, so that the cleaning water can drip and reduce adhesion on the double-sided filter screen plates 67.

[0057] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
