Description

Technical Field

[0001] The utility model relates to the technical field of multi-layer filtration, in particular to a multi-layer filtration mechanism for demulsifier production. Background Art

[0002] Demulsifier is a surfactant that can destroy the structure of emulsified liquid to separate the phases in the emulsion. Crude oil demulsification refers to the use of the chemical action of demulsifier to separate the oil and water in the emulsified oil-water mixture to achieve the purpose of dehydrating crude oil to ensure the water content standard of crude oil export. Demulsifier is easily soluble in water, and the aqueous solution is milky white. When the demulsifier is produced, it will contain a certain amount of particulate matter. It is necessary to use a filtering device to filter the particulate matter in the demulsifier, so as to facilitate subsequent production and ensure the production quality of the demulsifier.

[0003] After searching, the Chinese patent publication number CN213643242U discloses a multi-layer filter for demulsifier production, which mainly realizes multi-stage filtration of materials through multiple layers of filter frames with different apertures, and guides the filtered particles out through a lifting pipe.

[0004] By comparing with the existing technologies in related fields, it can be seen that when the emulsifier is subjected to multi-stage filtration, some particles will be blocked in the filter holes of the filter screen, and the demulsifier is an emulsion-like material with a certain viscosity. The emulsifier will form a certain liquid film in the smaller filter holes, affecting the filtration of the emulsifier. Only scraping the surface of the filter screen cannot clean the blockage in the filter holes, which affects the efficiency of emulsifier filtration. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-layer filtering mechanism for demulsifier production in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A multi-layer filtering mechanism for demulsifier production comprises a production box, a guide mechanism and a driving mechanism are arranged on the side of the production box, a discharge valve is arranged on the lower surface of the production box, filters are arranged at equal distances inside the production box, the aperture of the filters decreases from top to bottom, a rotating drum and a feeding pipe are installed on the upper surface of the production box, the rotating drum is rotatably connected to the production box and the filter, the rotating drum is connected to the driving mechanism, an anti-blocking mechanism is arranged on the part of the rotating drum located in the production box, the anti-blocking mechanism is slidably connected to the filter, the feed pipe is connected to an external conveying device, the external conveying device conveys the demulsifier into the production box through the feeding pipe, the demulsifier is filtered through the filter screens arranged at equal distances, the filtered particles remain on the filter screen, the filtered demulsifier is discharged through the discharge valve, during the filtering process, the driving mechanism drives the anti-blocking mechanism to rotate through the rotating drum, the filter screen is processed by the anti-blocking mechanism to avoid blockage of the filter screen, and the filtering efficiency is ensured, after the filtering is completed, the filtered particles on the filter screen are discharged and collected through the guide mechanism;

[0008] The anti-clogging mechanism includes a valve seat, an upper scraper and a lower scraper. The valve seat is installed on the upper surface of the production box, the valve seat is rotatably connected to the rotary drum, the upper scraper and the lower scraper are equidistantly installed on the rotary drum, the upper scraper is an arc-shaped plate, the upper scraper is slidably connected to the upper surface of the filter screen, the lower scraper is slidably connected to the lower surface of the filter screen, an air guide cavity is arranged in the lower scraper, nozzles are equidistantly arranged on both sides of the lower scraper, a one-way valve is installed on the nozzle, the valve seat is connected to an external air supply device, the upper scraper and the lower scraper are installed at a certain angle, and there is a staggered height difference between the lower end of the upper scraper and the upper end of the lower scraper, and the rotary drum drives the upper scraper and the lower scraper along When the filter rotates, the upper scraper scrapes the debris filtered on the filter. At the same time, when the upper scraper and the lower scraper rotate, the filter between the upper scraper and the lower scraper forms a certain distortion to prevent the particles from clogging the filter holes on the filter. At the same time, the external gas supply device conveys the gas to the nozzle through the rotating drum and the air guide cavity, and sprays it through the one-way valve. The gas sprayed through the one-way valve blows out the particles in the filter holes of the filter, and can prevent the emulsifier from forming a tensioned liquid film in the filter holes to affect the demulsifier from passing through the filter holes, effectively avoiding the blockage of the filter and ensuring the filtering efficiency of the filter for the demulsifier.

[0009] Furthermore, the air guide cavity is a conical shape with one end narrow and the other end wide, and the nozzles on both sides of the lower scraper are staggered. Since the gas flow rate is slow in the wide part and fast in the narrow part, the air guide cavity is designed with a conical shape with one end narrow and the other end wide, which ensures that the airflow in the air guide cavity can be evenly dispersed into the nozzles. Through the staggered nozzles, the filter can be effectively blown to ensure normal filtration of the filter.

[0010] Furthermore, the driving mechanism includes a motor, a belt and a driven pulley. The motor is installed on the side of the production box. A driving pulley is installed on the output shaft of the motor. The driven pulley is installed on the rotating drum. The driven pulley is connected to the driving pulley through a belt transmission. The motor and the external controller are electrically connected. The motor works using existing technology. The motor drives the rotating drum to rotate through the driving pulley, belt and driven pulley, thereby driving the scraper and the lower scraper to clean the filter.

[0011] Furthermore, the impurity guiding mechanism includes an impurity guiding pipe and an impurity outlet. The impurity guiding pipe is arranged on the side of the production box, and the impurity outlets are arranged at equal distances at the installation position of the impurity guiding pipe on the production box. The impurity outlet connects the production box and the impurity guiding pipe. The impurity outlet and the upper surface of the filter are at the same height. A sealing mechanism is arranged in the impurity guiding pipe, and the impurity outlet is closed or opened by the sealing mechanism, and the filtered particulate matter on the filter is guided out and collected by the impurity outlet and the impurity guiding pipe.

[0012] Furthermore, the sealing mechanism includes a hydraulic cylinder, which is installed on the side of the impurity guiding pipe, and the telescopic end of the hydraulic cylinder is slidably connected to the impurity guiding pipe. A sealing plate is installed on the end of the telescopic end of the hydraulic cylinder located in the impurity guiding pipe, and the sealing plate is slidably and sealingly connected to the impurity outlet. The hydraulic cylinder and an external controller are electrically connected. The hydraulic cylinder works using existing technology, and the sealing plate is driven by the hydraulic cylinder to close or open the impurity outlet, thereby preventing the demulsifier from flowing out through the impurity outlet during the demulsifier filtration process, and can export the filtered particulate matter through the impurity outlet after the demulsifier filtration is completed.

[0013] Furthermore, an exhaust pipe is installed on the upper surface of the production box, and the exhaust pipe is connected to an external exhaust gas treatment device. The gas in the production box is exported to the external exhaust gas treatment device through the exhaust pipe to avoid pollution to the external environment and ensure the pressure balance in the production box.

[0014] Furthermore, an observation window is provided on the side of the production box, and a transparent plate is installed in the observation window. The filter inside the production box can be easily viewed through the observation window and the transparent plate, so as to determine the number of filtered particles on the filter, thereby facilitating the discharge of filtered particles according to the number of filtered particles on the filter.

[0015] The beneficial effects compared with the prior art are as follows:

[0016] 1. The upper scraper is used to scrape the filtered particles on the filter screen to avoid the accumulation of filtered particles. The upper and lower scrapers are used to twist the butterfly filter screen. The external air supply device sprays air to the filter screen through the valve seat, the rotating drum, the air guide cavity, the nozzle and the one-way valve, so that the particles and debris in the filter holes on the filter screen can be blown out. The ejected airflow prevents the emulsifier from forming a tensioned liquid film in the filter hole to affect the demulsifier from passing through the filter hole, effectively avoiding the filter screen from being blocked and ensuring the filter efficiency of the filter screen for the demulsifier.

[0017] 2. The upper scraper rotates in the opposite direction to guide and push the filtered particles on the filter, so that the filtered particles enter the impurity guide pipe through the impurity outlet for export and collection, thereby effectively improving the efficiency of exporting and collecting the filtered particles on the filter.

[0029] like Figure 1-Figure 8 As shown, a multi-layer filtering mechanism for demulsifier production includes a production box 1, a guide mechanism and a driving mechanism 3 are arranged on the side of the production box 1, a discharge valve 2 is arranged on the lower surface of the production box 1, and filter screens 11 are arranged at equal intervals inside the production box 1. The apertures of the filter screens 11 decrease from top to bottom. A rotating drum 6 and a feeding pipe 7 are installed on the upper surface of the production box 1. The rotating drum 6 is rotatably connected to the production box 1 and the filter screen 11. The rotating drum 6 is connected to the driving mechanism 3. An anti-blocking mechanism 4 is arranged on the part of the rotating drum 6 located in the production box 1, and the anti-blocking mechanism 4 is slidably connected to the filter screen 11. Figure 1 , Figure 2 As shown, the feed pipe 7 is connected to the external conveying device, and the external conveying device conveys the demulsifier into the production box 1 through the feed pipe 7, and the demulsifier is filtered through the filter screen 11 arranged at equal distances, and the filtered particles remain on the filter screen 11. The filtered demulsifier is discharged through the discharge valve 2. During the filtering process, the driving mechanism 3 drives the anti-blocking mechanism 4 to rotate through the drum 6, and the filter screen 11 is processed by the anti-blocking mechanism 4 to avoid clogging of the filter screen 11, thereby ensuring the filtering efficiency. After the filtering is completed, the filtered particles on the filter screen 11 are discharged and collected through the impurity guide mechanism;

[0030] The anti-clogging mechanism 4 includes a valve seat 41, an upper scraper 42, and a lower scraper 43. The valve seat 41 is installed on the upper surface of the production box 1, and the valve seat 41 is rotatably connected to the rotating drum 6. The upper scraper 42 and the lower scraper 43 are evenly installed on the rotating drum 6. The upper scraper 42 is an arc-shaped plate. The upper scraper 42 is slidably connected to the upper surface of the filter screen 11, and the lower scraper 43 is slidably connected to the lower surface of the filter screen 11. An air guide cavity 46 is arranged in the lower scraper 43, and nozzles 44 are equidistantly arranged on both sides of the lower scraper 43. A one-way valve 45 is installed on the nozzle 44. Figure 1-Figure 8As shown, the valve seat 41 is connected to the external air supply device, the upper scraper 42 and the lower scraper 43 are installed at a certain angle, and the lower end of the upper scraper 42 and the upper end of the lower scraper 43 are staggered in height difference. When the filter 11 filters the demulsifier, the drum 6 drives the upper scraper 42 and the lower scraper 43 to rotate along the filter 11, and the debris filtered on the filter 11 is scraped by the upper scraper 42. At the same time, when the upper scraper 42 and the lower scraper 43 rotate, due to the certain height difference between the upper scraper 42 and the lower scraper 43, the filter 11 between the upper scraper 42 and the lower scraper 43 is twisted to a certain extent, thereby facilitating the removal of particles in the filter holes and avoiding the blockage of particles in the filter holes on the filter 11. At the same time, the external air supply device The gas is transported to the air guide chamber 46 through the rotating drum 6, and then transported to the nozzle 44 through the air guide chamber 46 and sprayed out through the one-way valve 45. The one-way valve 45 prevents the demulsifier from entering the nozzle 44 and the air guide chamber 46. The gas sprayed through the one-way valve 45 blows out the particles in the filter holes on the filter 11, and the inside of the filter holes is blown by the sprayed airflow to prevent the emulsifier from forming a tensioned liquid film in the filter holes that affects the demulsifier from passing through the filter holes, effectively preventing the filter 11 from being blocked, and ensuring the filtering efficiency of the filter 11 for the demulsifier. Since the upper scraper 42 is an arc-shaped plate, when the upper scraper 42 rotates in the opposite direction, the filtered particles are guided and pushed by the upper scraper 42, thereby effectively improving the efficiency of extracting and collecting the filtered particles.

[0031] The air guide cavity 46 is a frustum-shaped cavity with one end narrow and the other end wide. The nozzles 44 on both sides of the lower scraper 43 are arranged alternately. Figure 7 As shown, since the gas flow rate is slow in the wide part and fast in the narrow part, the gas guide cavity 46 is designed as a cone with one end narrow and the other end wide, so as to ensure that the gas flow in the gas guide cavity 46 can be evenly dispersed into the nozzle 44. Figure 6 , Figure 7 As shown, the staggered arrangement of the nozzles 44 can effectively blow air onto the filter screen 11 to ensure normal filtration of the filter screen 11 .

[0032] The driving mechanism 3 includes a motor 31, a belt 33 and a driven pulley 34. The motor 31 is mounted on the side of the production box 1. The output shaft of the motor 31 is mounted with a driving pulley 32. The driven pulley 34 is mounted on the drum 6. The driven pulley 34 is connected to the driving pulley 32 through the belt 33. Figure 1-Figure 3 As shown, the motor 31 is electrically connected to the external controller, and the motor 31 works by adopting the existing technology. The motor 31 drives the active pulley 32 to rotate, and the active pulley 32 drives the driven pulley 34 to rotate through the belt 33. The driven pulley 34 drives the rotating drum 6 to rotate, thereby driving the upper scraper 42 and the lower scraper 43 to rotate, and the filter 11 is cleaned.

[0033] The impurity guiding mechanism includes an impurity guiding pipe 9 and an impurity outlet 10. The impurity guiding pipe 9 is arranged on the side of the production box 1.

A sealing plate 52 is installed on the end of the telescopic end of the hydraulic cylinder 51 located in the impurity guide pipe 9. The sealing plate 52 is slidably and sealingly connected to the impurity outlet 10. Figure 1 , Figure 2 As shown, the hydraulic cylinder 51 is electrically connected to the external controller, and the hydraulic cylinder 51 works by using the existing technology. When filtering the demulsifier, the sealing plate 52 is driven by the hydraulic cylinder 51 to close the outlet 10, thereby preventing the demulsifier from flowing out through the outlet 10 during the demulsifier filtering process. After the demulsifier filtering is completed, the sealing plate 52 is driven by the hydraulic cylinder 51 to open the outlet 10, thereby facilitating the filtered particles on the filter screen 11 to enter the outlet 10 for extraction and collection.

[0035] An exhaust pipe 8 is installed on the upper surface of the production box 1. Figure 1 , Figure 2 As shown, the exhaust pipe 8 is connected to the external exhaust gas treatment device, and the gas in the production box 1 is discharged to the external exhaust gas treatment device through the exhaust pipe 8 to avoid pollution to the external environment and ensure the pressure balance in the production box 1.

The filtered demulsifier is discharged from the mobile phone through the discharge valve 2;

[0038] During the demulsifier filtration process of the filter screen 11, Figure 1-Figure 3 As shown, the motor 31 drives the driving pulley 32 to rotate, the driving pulley 32 drives the driven pulley 34 to rotate through the belt 33, and the driven pulley 34 drives the rotating drum 6 to rotate; Figure 2 , Figure 4 , Figure 5 As shown, the rotary drum 6 drives the upper scraper 42 and the lower scraper 43 to rotate along the filter screen 11, and the upper scraper 42 scrapes the debris filtered on the filter screen 11. At the same time, when the upper scraper 42 and the lower scraper 43 rotate, due to a certain height difference between the upper scraper 42 and the lower scraper 43, the filter screen 11 between the upper scraper 42 and the lower scraper 43 is twisted to a certain extent;

[0039] At the same time, if Figure 1-Figure 7 As shown, the external gas delivery device delivers the gas to the gas guide cavity 46 through the drum 6, and then delivers the gas to the nozzle 44 through the gas guide cavity 46, and sprays it out through the one-way valve 45.
