Description

Technical Field

[0001] This utility model relates to the field of crude oil purification technology, and in particular to a crude oil purification device for methylpyrimidine phosphorus. Background Technology

[0002] Crude methyl pyrimidine phosphate is mainly used to process various formulations, such as emulsifiable concentrates, powders, and granules, and is widely used in agriculture, warehousing, and sanitation. In agriculture, it is used to control pests on rice, wheat, and corn, such as aphids, planthoppers, and leafhoppers. In warehousing, it is used to control storage pests, such as rice weevils, grain borers, and red flour beetles, protecting grains and other agricultural products from insect damage. In sanitation, it is used to control flies, mosquitoes, and cockroaches, improving environmental hygiene.

[0003] Crude methylpyrimidine phosphorus contains impurities, byproducts, and unreacted raw materials, resulting in low purity. Purification equipment uses various purification processes such as distillation, extraction, crystallization, and filtration to remove these impurities, thereby improving the purity of methylpyrimidine phosphorus and meeting the purity requirements of different application fields.

[0004] Commercially available crude oil refining equipment can achieve efficient separation of components in crude methylpyrimidine phosphorus by precisely controlling temperature and pressure based on the differences in boiling points, thus obtaining high-purity methylpyrimidine phosphorus. However, crude methylpyrimidine phosphorus contains some impurities. During the distillation process, these impurities will deposit on the inner wall of the equipment, the trays, or the packing, forming scale, which affects heat and mass transfer, and may even cause equipment blockage. Regular cleaning and maintenance are required, increasing production costs and downtime. Existing technology pre-treats the crude methylpyrimidine phosphorus before it is fed into the refining unit by using filtration to remove solid impurities, reduce impurity content, and improve the quality of the raw material. However, the pore size of the filter screen is relatively small, making it easy to be blocked by these impurities. The blockage problem is more serious when processing high-viscosity crude oil. Filter screen blockage leads to increased fluid resistance, reduced flow rate, and affects production efficiency. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a crude oil purification device for methylpyrimidine phosphorus, comprising a filter tank 1 for filtering impurities in the crude oil. A lid 3 is provided on the top of the filter tank 1 to seal it. A delivery pipe 4 is connected to the bottom wall of the filter tank 1, and the end of the delivery pipe 4 is connected to a distillation column 5. The distillation column 5 utilizes the difference in boiling points between methylpyrimidine phosphorus and other impurities in the crude oil, separating the methylpyrimidine phosphorus from the mixture through multiple partial vaporization and partial condensation processes, thereby improving its purity. The delivery pipe 4 is used to transport the filtered crude oil to the distillation column 5. The top wall of the filter barrel 1 has a circular groove 6, inside which a filter screen 7 is placed. The circular groove 6 is used to hold the filter screen 7. A fixing block 8 is fixedly connected to the middle of the front and rear sides of the bottom wall of the filter screen 7. A movable block 9 is slidably connected to the outer wall of the fixing block 8, and the movable block 9 is used to help pull out the filter screen 7. A sliding groove 10 is provided on the middle of the front and rear sides of the inner bottom wall of the circular groove 6. The sliding groove 10 is slidably connected to the fixing block 8 and is used to slide the fixing block 8. A sliding groove 11 is provided on the left and right sides of the middle of the inner wall of the sliding groove 10. A locking block 12 is slidably connected to the inner wall of the sliding groove 11 and is used to slide the locking block 12. A spring 13 is installed on the outer wall of the locking block 12. The spring 13 is used to rebound the locking block 12. A limit plate 14 is slidably connected to the outer wall of the locking block 12. The limit plate 14 is used to limit the movement distance of the locking block 12. The limit plate 14 is fixedly connected to the left and right sides of the inner wall of the slide trough 11. A cleaning mechanism 2 is provided inside the distillation column 5. The cleaning mechanism 2 is used to prevent scale formation on the inner wall and trays of the distillation column 5. A handle 19 is fixedly connected to the middle of the top wall of the bucket lid 3. The handle 19 is used to open the bucket lid 3. An anti-slip sleeve 20 is installed on the outer wall of the handle 19. The special texture or material on the surface of the anti-slip sleeve 20 can greatly increase the friction between the anti-slip sleeve and the hand. To ensure that the operator can firmly grip the handle 19 under various postures and forces, a fastening buckle 17 is fixedly connected to the middle of the front side of the outer wall of the filter bucket 1. The function of the fastening buckle 17 is to guide the buckle to the installation position smoothly, correctly and quickly during installation, and to provide an accurate positioning reference for the installation of the buckle, so as to ensure the precision and accuracy of the installation. A positioning buckle 18 is fixedly connected to the middle of the front side of the outer wall of the bucket cover 3. After a certain separation force is applied to the positioning buckle 18, the buckle will disengage, so that the two connecting parts are separated. The fastening buckle 17 and the positioning buckle 18 engage. The engagement of the fastening buckle 17 and the positioning buckle 18 can lock the bucket cover 3 and the filter bucket 1.

[0033] Specifically, the movable block 9 presses against the locking block 12, causing it to move on the slide groove 11. The locking block 12 rebounds through the spring 13, locking the movable block 9. Pulling the filter screen 7 upwards causes the movable block 9 to slide to the upper limit of the fixed block 8. The curvature of the movable block 9 increases the space of the locking block 12, allowing the filter screen 7 to be pulled out. Finally, the locking block 12 rebounds back to its original position through the spring 13. The handle 19 is used to open the bucket lid 3. The special texture or material on the surface of the anti-slip sleeve 20 can greatly increase the friction between the handle and the hand, ensuring that the operator can firmly grip the handle 19 under various postures and forces. The fastening buckle 17 guides the buckle to reach the installation position smoothly, correctly, and quickly during installation, providing an accurate positioning reference for the installation of the buckle and ensuring the precision and accuracy of the installation. After the positioning buckle 18 applies a certain separation force, the buckle will disengage, separating the two connecting parts. The combination of the fastening buckle 17 and the positioning buckle 18 can lock the bucket lid 3 and the filter bucket 1.

[0034] Reference Figure 1 and Figure 5 The cleaning mechanism 2 includes a motor 201, which is located in the middle of the top wall of the distillation column 5. A fixing frame 202 is fixedly connected to the bottom wall of the motor 201, and the fixing frame 202 is used to fix the motor 201. The bottom wall of the fixing frame 202 is fixedly connected to the middle of the top wall of the distillation column 5. A rotating shaft 203 is fixedly connected to the output end of the motor 201, and the motor 201 is used to rotate the rotating shaft 203. A connecting frame 204 is fixedly connected to the end of the rotating shaft 203, and the rotating shaft 203 drives the connecting frame 204 to rotate. Scrapers 205 are equidistantly installed around the outer wall of the connecting frame 204. The scrapers 205 effectively prevent the formation of scale and maintain... The cleanliness of the inner surface of the column ensures smooth heat transfer and material flow. A nozzle 206 is installed in the middle of the inner top wall of the connecting frame 204. The high-pressure water flow generated by the nozzle 206 impacts the inner wall and can wash away the dirt in the distillation column 5. An observation hole 23 is opened in the lower middle part of the front side of the outer wall of the distillation column 5. The operator can directly observe the gas-liquid flow state, liquid level, material color and transparency in the column through the observation hole 23. A glass plate 24 is fixedly connected to the outer wall of the observation hole 23. The glass plate 24 needs to fit tightly with the frame of the observation hole 23 to form a good sealing structure to prevent material and gas leakage in the column.

[0035] Specifically, when the equipment stops operating, the motor 201 is started. The motor 201 drives the rotating shaft 203 to rotate, and the rotating shaft 203 drives the connecting frame 204 to rotate. The connecting frame 204 has a scraper 205 and a nozzle 206. The rotation of the connecting frame 204 drives the scraper 205 and the nozzle 206 to rotate. The scraper 205 slowly and evenly scrapes the inner wall, and the high-pressure water flow generated by the nozzle 206 impacts the inner wall, which can wash away the dirt in the distillation column 5. The operator can directly observe the gas-liquid flow state, liquid level, material color and transparency in the column through the observation hole 23. The glass plate 24 needs to fit tightly with the frame of the observation hole 23 to form a good sealing structure to prevent material and gas leakage in the column.

[0036] Reference Figure 1 and Figure 2 A hinge 15 is installed on the rear side of the outer wall of the filter barrel 1. A bolt 16 is threaded on the rear side of the outer wall of the hinge 15. The bolt 16 is used to fix the hinge 15. The filter barrel 1 is rotatably connected to the barrel cover 3 through the hinge 15. The hinge 15 is used to rotate the barrel cover 3. A discharge pipe 21 is connected to the left side of the outer wall of the distillation column 5. The discharge pipe 21 is used to discharge the product that meets the purity requirements out of the distillation column 5 for subsequent processing, storage or further processing. A valve 22 is installed inside the discharge pipe 21. The valve 22 is used to control the discharge flow of the product or intermediate product, thereby maintaining the material balance in the distillation column 5. Support legs 25 are fixedly connected to the four corners of the bottom wall of the filter barrel 1 and the distillation column 5. The support legs 25 are used to support the filter barrel 1 and the distillation column 5 to ensure that the device remains stable during operation. Anti-slip pads 26 are installed on the bottom wall of the support legs 25. The anti-slip pads 26 can effectively prevent the support legs 25 from sliding on the ground and ensure that the filter barrel 1 and the distillation column 5 maintain a stable position during operation.

[0037] Specifically, hinge 15 allows the lid 3 to rotate on the filter barrel 1, bolt 16 is used to fix hinge 15 to the filter barrel 1, discharge pipe 21 is used to discharge products that have reached a certain purity requirement out of the distillation column 5 for subsequent processing, storage or further processing, valve 22 is used to control the discharge flow of products or intermediate products, thereby maintaining the material balance in the distillation column 5, support leg 25 is used to support the filter barrel 1 and the distillation column 5 to ensure that the device remains stable during operation, and anti-slip pad 26 can effectively prevent the support leg 25 from sliding on the ground, ensuring that the filter barrel 1 and the distillation column 5 maintain a stable position during operation.

[0038] Working principle: First, press down the filter screen 7 inside the filter canister 1. The movable block 9 presses against the locking block 12, causing it to move on the slide groove 11. The spring 13 rebounds and the locking block 12 locks the movable block 9. Pull the filter screen 7 upward so that the movable block 9 slides to the upper limit of the fixed block 8. The curvature of the movable block 9 increases the space of the locking block 12, allowing the filter screen 7 to be pulled out. Finally, the locking block 12 rebounds to its original position via the spring 13. Through the above operations, the filter screen 7 can be cleaned and replaced.

[0039] When the equipment stops running, the motor 201 is started. The motor 201 drives the rotating shaft 203 to rotate, and the rotating shaft 203 drives the connecting frame 204 to rotate. The connecting frame 204 has a scraper 205 and a nozzle 206. The rotation of the connecting frame 204 drives the scraper 205 and the nozzle 206 to rotate. The scraper 205 slowly and evenly scrapes the inner wall, and the high-pressure water flow generated by the nozzle 206 impacts the inner wall, which can wash away the dirt in the distillation column 5.
