Description

Technical Field

[0001] This utility model relates to the field of refrigeration oil treatment technology, specifically a high-efficiency filtration device for the pretreatment of refrigeration oil raw materials. Background Technology

[0002] With the rapid development of the refrigeration industry, refrigeration oil, as an important partner of refrigerants, plays a crucial role in the operation of refrigeration equipment. It not only provides necessary lubrication for the compressor but also helps remove heat and impurities generated within the system. However, refrigeration oil often requires a series of pretreatment steps before production, transportation, and use to ensure its purity meets high standards. Among these, filtration is a key step in removing solid particles, moisture, and other contaminants from the raw material.

[0003] In existing cooling oil filtration processes, the fixed feed location leads to impurities accumulating in specific areas of the filter screen, preventing even distribution across the entire surface. Over time, these impurities accumulate in certain sections of the screen, reducing filtration efficiency and increasing the burden on the screen. Even more problematic is the difficulty in quickly and effectively cleaning the accumulated residue. Typically, manual cleaning or screen replacement is required after a complete shutdown, which is time-consuming, significantly reduces the efficiency of the entire production process, and increases maintenance costs. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a high-efficiency filtration device for the pretreatment of refrigerated oil raw materials, which achieves high-efficiency filtration and automatic cleaning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency filtration device for pretreatment of refrigerated oil feedstock includes a housing with a drain pipe embedded in it. A main filter plate is fixedly installed inside the housing, with neither side of the main filter plate abutting against the housing. Side support filter plates are fixedly installed on both sides of the main filter plate, and a slag collection and leakage box is provided on the side support filter plate. A hollow block is slidably installed on the housing, with an inlet pipe embedded in the hollow block. An outlet is equidistantly embedded on the side of the hollow block facing the main filter plate. A drive mechanism is provided inside the housing, and cleaning mechanisms are provided on both sides of the hollow block.

[0007] Preferably, the drive mechanism includes two fixed frames, which are respectively fixedly installed on the front and rear sides of the housing. Threaded rods are rotatably installed inside each of the two fixed frames. A synchronous chain is installed between the two threaded rods via a sprocket. Nut pairs are threadedly installed on each of the two threaded rods. Connecting blocks are fixedly installed on each of the two nut pairs. The two connecting blocks are fixedly connected to the hollow block.

[0008] Preferably, a servo motor is mounted on one of the mounting brackets, and the output end of the servo motor shaft is fixedly connected to the axis of one of the threaded rods.

[0009] Preferably, the cleaning mechanism includes a mounting frame, which is fixedly mounted on a hollow block. A fixed plate is fixedly mounted on the mounting frame, and springs are fixedly mounted at equal intervals inside the fixed plate. A movable plate is fixedly mounted on the other side of the springs. The movable plate is slidably mounted inside the fixed plate. A cleaning brush is embedded in the side of the movable plate away from the fixed plate, and the cleaning brush directly abuts against the main filter plate.

[0010] Preferably, a positioning block is fixedly installed on the side wall of the slag collection and leakage box, and a positioning groove adapted to the positioning block is opened in the corresponding position of the box body.

[0011] Preferably, a handle is fixedly installed on the slag collection and leakage box.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention achieves high-efficiency filtration and automatic cleaning functions through a meticulously designed structure. The main filter plate and its two side support filter plates ensure that impurities in the refrigeration oil feedstock are effectively intercepted. Simultaneously, the slag and liquid collection tank collects these impurities and achieves solid-liquid separation. The hollow block and its liquid outlet design ensure that the liquid to be filtered is evenly distributed on the surface of the main filter plate, improving filtration efficiency. The drive mechanism uses servo motors, threaded rods, and synchronous chains to precisely control the position of the hollow block, ensuring uniform liquid coverage while supporting cleaning operations without stopping the machine. The cleaning mechanism uses spring-adjustable pressure to ensure that the cleaning brush continuously and effectively removes impurities from the main filter plate, preventing clogging and maintaining filtration performance. Furthermore, the easy-to-disassemble design of the slag and liquid collection tank facilitates cleaning or replacement by users, reducing cleaning time and improving overall work efficiency and ease of use. This design not only improves filtration effect but also significantly reduces maintenance costs, making it ideal for industrial applications. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 6 A high-efficiency filtration device for pretreatment of refrigeration oil feedstock includes a housing 1, on which a drain pipe 3 is embedded. The housing 1 serves as the main structure of the entire filtration device, accommodating and supporting other components. The drain pipe 3 is used to discharge the filtered liquid, facilitating subsequent collection or further treatment of the filtered refrigeration oil.

[0023] A main filter plate 20 is fixedly installed in the housing 1. The left and right sides of the main filter plate 20 do not abut against the housing 1. Side support filter plates 21 are fixedly installed on both sides of the main filter plate 20. A sludge collection and leakage box 8 is provided on the side support filter plate 21.

[0024] The main filter plate 20 is the main component of the filter, which can filter impurities in the refrigeration oil feedstock. Its left and right sides do not abut against the housing 1, which can ensure the smooth fall of the sludge. The side support filter plate 21 supports the main filter plate 20 and the sludge and liquid collection box 8. At the same time, the sludge and liquid collection box 8 can be used to collect the impurities intercepted during the filtration process. The bottom of the sludge and liquid collection box 8 is provided with an opening, which allows the liquid to seep out and flow into the housing 1 through the side support filter plate 21, so as to achieve solid-liquid separation.

[0025] It is worth noting that the liquid level inside the tank 1 must never exceed the bottom surface of the side-supported filter plate 21 in order to avoid buoyancy affecting the interception of impurities.

[0026] A hollow block 4 is slidably installed on the housing 1. An inlet pipe 5 is embedded in the hollow block 4. An outlet 17 is equidistantly embedded on the side of the hollow block 4 facing the main filter plate 20. The hollow block 4 can slide on the housing 1. The inlet pipe 5 is used to introduce the raw material of the refrigeration oil to be filtered into the hollow block 4. The outlet 17 sprays the raw material of the refrigeration oil in the hollow block 4 evenly onto the main filter plate 20, so that the raw material can come into more complete contact with the main filter plate 20 for filtration.

[0027] The housing 1 is equipped with a drive mechanism, and the hollow block 4 has cleaning mechanisms on both its left and right sides. The drive mechanism drives the hollow block 4 to slide on the housing 1, changing the position of the liquid outlet 17, so that the refrigeration oil feedstock can evenly cover the main filter plate 20, improving the filtration effect. The cleaning mechanisms are used to clean the main filter plate 20 during the sliding of the hollow block 4, preventing impurities from clogging the main filter plate 20 and ensuring continuous and efficient filtration.

[0028] The drive mechanism includes two fixed frames 2. The two fixed frames 2 are fixedly installed on the front and rear sides of the housing 1 respectively. Threaded rods 11 are rotatably installed inside the two fixed frames 2. A synchronous chain 7 is installed between the two threaded rods 11 through a sprocket. Nut pairs 12 are threadedly installed on the two threaded rods 11. Connecting blocks 13 are fixedly installed on the two nut pairs 12. The two connecting blocks 13 are fixedly connected to the hollow block 4.

[0029] A servo motor 6 is mounted on one of the mounting brackets 2, and the output end of the shaft of the servo motor 6 is fixedly connected to the shaft of one of the threaded rods 11.

[0030] After the servo motor 6 is started, it drives one of the threaded rods 11 to rotate, and the other threaded rod 11 rotates synchronously through the synchronous chain 7. The rotation of the threaded rod 11 causes the nut pair 12 to move along the threaded rod 11. The nut pair 12 drives the hollow block 4 to slide on the housing 1 through the connecting block 13, thereby adjusting the position of the liquid outlet 17.

[0031] Preferably, the sprocket and the synchronous chain 7 should be driven by a tooth or chain to ensure the transmission ratio and avoid slippage.

[0032] The cleaning mechanism includes a mounting frame 14, which is fixedly mounted on the hollow block 4. A fixed plate 15 is fixedly mounted on the mounting frame 14. Springs 18 are fixedly mounted at equal intervals inside the fixed plate 15. A movable plate 19 is fixedly mounted on the other side of the springs 18. The movable plate 19 is slidably mounted inside the fixed plate 15. A cleaning brush 16 is embedded in the side of the movable plate 19 away from the fixed plate 15. The cleaning brush 16 directly abuts against the main filter plate 20.

[0033] When the hollow block 4 slides, the mounting bracket 14 installed on the hollow block 4 moves accordingly. The cleaning brush 16 is always in contact with the main filter plate 20 due to the action of the spring 18, and cleans the surface of the main filter plate 20 during the movement. The spring 18 can ensure that there is appropriate pressure between the cleaning brush 16 and the main filter plate 20, and make appropriate compensation for the extension length of the cleaning brush 16 after wear, thereby improving the cleaning effect.

[0034] A positioning block 22 is fixedly installed on the side wall of the slag collection and leakage box 8, and a positioning groove 10 adapted to the positioning block 22 is opened in the corresponding position of the box body 1.

[0035] A handle 9 is fixedly installed on the slag collection and leakage tank 8.

[0036] The cooperation between the positioning block 22 and the positioning groove 10 ensures that the slag collection and leakage box 8 can be accurately installed in the designated position inside the box 1, guaranteeing its stable operation. When impurities accumulate in the slag collection and leakage box 8 to a certain extent, the slag collection and leakage box 8 can be easily removed from the box 1 through the handle 9 for cleaning or replacement.

[0037] During the cleaning process, the hollow block 4 only needs to be moved directly above the main filter plate 20, without moving to the sides, to carry out the cleaning without stopping the machine.

[0038] The working process of this utility model is as follows: The raw material for filtering refrigeration oil enters the hollow block 4 through the inlet pipe 5. Since the hollow block 4 can slide on the housing 1 under the action of the drive mechanism, after the servo motor 6 is started, the motor drives one of the threaded rods 11 to rotate, and through the synchronous chain 7, the other threaded rod 11 rotates synchronously. The rotation of the threaded rod 11 causes the nut pair 12 to move along the threaded rod 11, and the nut pair 12 drives the hollow block 4 to slide through the connecting block 13. The raw material for refrigeration oil is evenly sprayed onto the main filter plate 20 from the outlet 17 on the hollow block 4.

[0039] The main filter plate 20 serves as the primary filtration component, filtering impurities from the refrigeration oil feedstock. The left and right sides of the main filter plate 20 do not abut against the housing 1, ensuring that the sludge intercepted during filtration can fall smoothly. The side support filter plates 21 support the main filter plate 20 and the sludge collection and leakage tanks 8. During the sliding of the hollow block 4, the cleaning mechanism functions. The mounting bracket 14 installed on the hollow block 4 moves accordingly, and the cleaning brush 16, due to the action of the spring 18, always abuts against the main filter plate 20, cleaning the surface of the main filter plate 20 during movement to prevent impurities from clogging it and ensuring continuous and efficient filtration. Impurities ultimately end up in the sludge collection and leakage tanks 8 on both sides, while the liquid continues to flow downwards through the side support filter plates 21 via the leakage function of the sludge collection and leakage tanks 8, achieving solid-liquid separation. The filtered liquid is discharged from the housing 1 through the drain pipe 3 (which can be connected to a corresponding pump to improve output), facilitating subsequent collection or further processing.

[0040] Spring 18 also ensures appropriate pressure between cleaning brush 16 and main filter plate 20, and provides appropriate compensation for the extension length of cleaning brush 16 after wear.

[0041] When the impurities in the slag collection and leakage box 8 accumulate to a certain extent, the slag collection and leakage box 8 can be easily removed from the box 1 for cleaning or replacement using the handle 9. During cleaning, the hollow block 4 can be moved only above the main filter plate 20 without moving to the sides, thus achieving cleaning without stopping the machine.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
