Description

Technical Field

[0001] This utility model relates to the field of oil purification technology, and more specifically, it relates to a purification device for oil used in the chemical industry. Background Technology

[0002] In the chemical industry, oil purification equipment is a crucial step in ensuring oil quality, especially the purification and filtration of industrial oils. Purification equipment removes impurities, mixed oils, and other contaminants from the oil, ensuring its purity and performance. However, existing oil purification equipment presents significant inconveniences in terms of oil discharge and the installation and removal of filter plates.

[0003] The design of the purification oil discharge channel in existing equipment is often rudimentary, resulting in resistance and poor flow of the purified oil during discharge. Due to unreasonable structure or angle of the discharge pipe, oil can easily accumulate in the container during discharge, leading to incomplete discharge. This not only wastes the purified oil but may also leave residual oil inside the equipment, affecting the next purification process.

[0004] In oil purification equipment used in the chemical industry, filter plates are key components in the purification process. Current filter plate installation and removal processes are typically complex, often requiring multiple steps. These steps include manually disassembling the filter plate, cleaning the filter element, and reinstalling the filter plate, which is tedious and requires certain skills and experience. This process is not only time-consuming but also prone to operational errors, affecting the normal operation of the equipment. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a purification device for oil in the chemical industry, which has the following beneficial effects:

[0018] This utility model is equipped with a purification extraction mechanism. The purification extraction mechanism forms a closed and efficient oil purification system through the coordinated work of the purification box and the extraction pump. The dual-set refueling pipe design improves refueling efficiency, and the extraction pump generates stable suction to ensure that the oil is fully filtered.

[0030] Please see Figures 1-5 A chemical industrial oil purification device includes a chassis 1, a purification extraction mechanism, a filter plate clamping mechanism, and a clamping auxiliary mechanism. The purification extraction mechanism includes a purification box 2 and an extraction pump 3. The purification box 2 and the extraction pump 3 are installed at the top end of the chassis 1. An extraction pipe 4 is installed at the bottom end of the purification box 2, and the extraction pump 3 is installed on the extraction pipe 4. A collection pipe 5 is installed at the top end of the chassis 1, and the collection pipe 5 is connected to the extraction pipe 4. The filter plate clamping mechanism includes a clamping pipe 6 and a clamping rod 7. A friction groove 8 is formed on the outer wall of the clamping rod 7. A counter-tension spring rod 9 is slidably installed laterally on the outer wall of the clamping pipe 6. An elastic frame 10 is installed between adjacent counter-tension spring rods 9. A rotating sleeve 11 is rotatably installed on the upper limit of the outer wall of the clamping pipe 6. A slope groove 12 is formed on the inner wall of the rotating sleeve 11. The slope groove 12 presses against the counter-tension spring rod 9, so that the elastic frame 10 is embedded in the friction groove 8.

[0031] In this embodiment, the purification extraction mechanism works in concert with the purification tank 2 and the extraction pump 3. First, the industrial oil to be purified is injected into the purification tank 2 through the filling pipe 22 at the top of the purification tank 2. The extraction pump 3 is installed on the extraction pipe 4 connected to the bottom of the purification tank 2. After starting, it generates suction force, causing the industrial oil to flow from the purification tank 2 through the filter assembly 101 for filtration and purification. The purified oil enters the manifold 5 installed at the top of the vehicle panel 1 through the extraction pipe 4, and then is discharged through the discharge hose 23 and the discharge valve pipe 24. Throughout the process, the extraction pump 3 provides continuous and stable suction force to ensure that the industrial oil can fully pass through the filter assembly 101 to achieve effective purification. The filter plate clamping mechanism uses the clamping pipe 6 and the clamping rod 7 to fix and replace the filter assembly 101. The outer wall of the clamping rod 7 The filter assembly 101 is provided with a friction groove 8, one end of which passes through the longitudinal plate 26 and the purification box 2 and engages with the clamping pipe 6. Multiple anti-tension spring rods 9 are slidably installed on the outer wall of the clamping pipe 6, and an elastic frame 10 is installed between adjacent anti-tension spring rods 9. A rotating sleeve 11 is installed on the outer wall of the clamping pipe 6 to limit rotation. A slope groove 12 is provided on the inner wall of the rotating sleeve 11. When it is necessary to install or replace the filter assembly 101, the rotating sleeve 11 is rotated, and the slope groove 12 releases the pressure on the anti-tension spring rods 9. The elastic frame 10 is withdrawn from the friction groove 8. At this time, the clamping rod 7 can be pulled out. After installing the new filter assembly 101, the rotating sleeve 11 is rotated in the opposite direction, and the slope groove 12 presses against the anti-tension spring rods 9, so that the elastic frame 10 is embedded in the friction groove 8, and the clamping rod 7 is firmly fixed to ensure the stable operation of the filter assembly 101.

[0032] The snap-fit ​​auxiliary mechanism includes a connecting plate 13 and a pair of shrink blocks 14. The connecting plate 13 is installed at the bottom end of the outer wall of the snap-fit ​​tube 6. Multiple sets of shrink blocks 14 are slidably installed at the top end of the connecting plate 13. The shrink blocks 14 are arranged in multiple pairs. A shrink spring 15 is installed between the pairs of shrink blocks 14. A rotating ball block 16 is installed at the bottom end of the rotating sleeve 11. Multiple sets of rotating ball blocks 16 are arranged. The rotating ball blocks 16 pass through the pairs of shrink springs 15 in sequence to make the rotating sleeve 11 rotate stably. A rotation limiting ring 17 is threadedly connected to the outer wall of the snap-fit ​​tube 6. A clamping ring 18 is slidably installed on the outer wall of the snap-fit ​​tube 6. The clamping ring 18 and the rotation limiting ring 17 are threadedly pushed together. The clamping ring 18 can press against the top of the rotating sleeve 11.

[0033] In this embodiment, the snap-fit ​​auxiliary mechanism enhances the stability of the rotating sleeve 11 through the connecting plate 13 and the countersinking blocks 14. The connecting plate 13 is installed at the bottom of the outer wall of the snap-fit ​​tube 6. Multiple sets of paired countersinking blocks 14 are slidably mounted on the countersinking rails 28 at the top of the connecting plate 13. Countersinking springs 15 are installed between the pairs of countersinking blocks 14. Multiple sets of rotating ball blocks 16 are installed at the bottom of the rotating sleeve 11. The rotating ball blocks 16 pass through the pairs of countersinking springs 15 in sequence. When the rotating sleeve 11 is rotated, the rotating ball blocks 16 run stably under the elastic action of the countersinking springs 15, ensuring smooth rotation. At the same time, a limiting rotating ring 17 is threadedly connected to the outer wall of the snap-fit ​​tube 6, and a clamping ring 18 is slidably mounted thereon. By rotating the limiting rotating ring 17, it engages with the clamping ring 18 and is threadedly pushed forward. The clamping ring 18 presses against the top of the rotating sleeve 11, further fixing the position of the rotating sleeve 11 and preventing loosening during operation.

[0034] Please see Figures 1-5 As a supplementary embodiment of a chemical product industrial oil purification equipment for the purification extraction mechanism, filter plate clamping mechanism and clamping auxiliary mechanism: Wheels 19 are installed around the bottom of the vehicle plate 1, and a push handle 20 is installed at one end of the vehicle plate 1. A box cover 21 is installed at the top of the purification box 2. A filling pipe 22 is installed through the box cover 21, and two sets of filling pipes 22 are provided. One end of the manifold 5 is connected to a discharge hose 23 and a discharge valve pipe 24, and two sets of discharge valve pipe 24 and discharge hose 23 are provided respectively. Sealing gaskets 25 are installed on both sides of the purification box 2. The clamping pipe 6 is connected to the sealing gaskets 25. Longitudinal plates 26 are installed at both ends of the filter assembly 101. An end plate 27 is installed at one end of the clamping rod 7. One end of the clamping rod 7 passes through the longitudinal plate 26 and the purification box 2 and is clamped with the clamping pipe 6. A shrinking rail 28 is installed at the top of the connecting plate 13, and the shrinking block 14 is slidably installed on the shrinking rail 28.

[0035] More specifically, the equipment is moved to the working position by the wheels 19 around the bottom of the vehicle platform 1 and the push handle 20 at one end. The locking rod 7 is passed through the longitudinal plates 26 at both ends of the filter assembly 101 and the purification box 2, and locked in place with the locking pipe 6. The rotating sleeve 11 is rotated so that the slope groove 12 presses against the anti-tension spring rod 9, and the elastic frame 10 is embedded in the friction groove 8 and fixed firmly. The rotation limiting ring 17 is rotated so that the clamping ring 18 presses against the top of the rotating sleeve 11, further fixing the position of the rotating sleeve 11. The box cover 21 on the top of the purification box 2 is opened, and the industrial oil to be purified is injected into the purification box 2 through the oil filling pipe 22. The extraction pump 3 is started, and the industrial oil is purified through the filter assembly 101 under the action of suction. The purified oil enters the manifold 5 through the extraction pipe 4, and then is discharged through the discharge hose 23 and the discharge valve pipe 24. When the filter assembly 101 needs to be replaced, the clamping ring 18 is loosened first, then the rotating sleeve 11 is rotated to release the locking mechanism, the locking rod 7 is taken out, and a new filter assembly 101 is replaced.

[0036] In summary, during the use or operation of the overall equipment: When the purification extraction mechanism is required to operate, the purification extraction mechanism works in concert with the purification tank 2 and the extraction pump 3. First, the industrial oil to be purified is injected into the purification tank 2 through the filling pipe 22 at the top of the purification tank 2. The extraction pump 3 is installed on the extraction pipe 4 connected to the bottom of the purification tank 2. After starting, it generates suction force, causing the industrial oil to flow from the purification tank 2 through the filter assembly 101 for filtration and purification. The purified oil enters the manifold 5 installed at the top of the vehicle plate 1 through the extraction pipe 4, and is then discharged through the discharge hose 23 and the discharge valve pipe 24. Throughout the process, the extraction pump 3 provides continuous and stable suction force to ensure that the industrial oil can fully pass through the filter assembly 101 to achieve the purpose of effective purification.

[0037] When the filter plate clamping mechanism is in operation, it fixes and replaces the filter assembly 101 through the clamping tube 6 and the clamping rod 7. The outer wall of the clamping rod 7 is provided with a friction groove 8, one end of which passes through the longitudinal plate 26 and the purification box 2 and cooperates with the clamping tube 6. Multiple anti-tension spring rods 9 are slidably installed on the outer wall of the clamping tube 6, and an elastic frame 10 is installed between adjacent anti-tension spring rods 9. A rotating sleeve 11 is installed on the outer wall of the clamping tube 6 to limit rotation. The inner wall of the rotating sleeve 11 is provided with a slope groove 12. When the filter assembly 101 needs to be installed or replaced, the rotating sleeve 11 is rotated, and the slope groove 12 releases the pressure on the anti-tension spring rods 9. The elastic frame 10 is withdrawn from the friction groove 8. At this time, the clamping rod 7 can be pulled out. After installing the new filter assembly 101, the rotating sleeve 11 is rotated in the opposite direction, and the slope groove 12 presses against the anti-tension spring rod 9, so that the elastic frame 10 is embedded in the friction groove 8, firmly fixing the clamping rod 7 and ensuring the stable operation of the filter assembly 101.

[0038] When the locking auxiliary mechanism is required to operate, it enhances the stability of the rotating sleeve 11 through the connecting plate 13 and the counterweights 14. The connecting plate 13 is installed at the bottom of the outer wall of the locking tube 6. Multiple sets of paired counterweights 14 are slidably mounted on the counterweight rails 28 at the top of the connecting plate 13. Counterweight springs 15 are installed between the pairs of counterweights 14. Multiple sets of rotating ball blocks 16 are installed at the bottom of the rotating sleeve 11. The rotating ball blocks 16 pass through the pairs of counterweight springs 15 in sequence. When the rotating sleeve 11 is rotated, the rotating ball blocks 16 run stably under the elastic action of the counterweight springs 15, ensuring smooth rotation. At the same time, a limiting rotating ring 17 is threadedly connected to the outer wall of the locking tube 6, and a clamping ring 18 is slidably mounted thereon. By rotating the limiting rotating ring 17, it engages with the clamping ring 18 and is threadedly pushed forward. The clamping ring 18 presses against the top of the rotating sleeve 11, further fixing the position of the rotating sleeve 11 and preventing loosening during operation.

[0039] Move the equipment to the working position using the wheels 19 around the bottom of the vehicle platform 1 and the push handle 20 at one end. Pass the locking rod 7 through the longitudinal plates 26 at both ends of the filter assembly 101 and the purification box 2, and lock it in place with the locking pipe 6. Rotate the rotating sleeve 11 so that the slope groove 12 presses against the anti-tension spring rod 9, and the elastic frame 10 is embedded in the friction groove 8 and firmly fixed. Rotate the limiting ring 17 so that the clamping ring 18 presses against the top of the rotating sleeve 11 to further fix the position of the rotating sleeve 11. Open the box cover 21 on the top of the purification box 2 and inject the industrial oil to be purified into the purification box 2 through the oil filling pipe 22. Start the extraction pump 3. The industrial oil is purified by the suction force through the filter assembly 101. The purified oil enters the manifold 5 through the extraction pipe 4 and is then discharged through the discharge hose 23 and the discharge valve pipe 24. When the filter assembly 101 needs to be replaced, first loosen the clamping ring 18, then rotate the rotating sleeve 11 to release the locking mechanism, take out the locking rod 7, and replace it with a new filter assembly 101.
