Description

Technical Field

[0001] This utility model relates to the technical field of venting devices for liquid storage tanks, and in particular to a venting device for an industrial-grade mixed oil storage tank. Background Technology

[0002] Industrial-grade blended oil is usually a mixture of various oils and greases. Currently, waste cooking oil can be processed through steps such as heating, settling, and adding activated clay for degreasing to obtain industrial oil. This method can reuse waste oil, reduce resource waste, and improve resource utilization. After refining the cooking oil into industrial oil, it needs to be poured into a tank for storage. However, there is often a certain amount of gas in the tank, which prevents the industrial oil from flowing into the tank normally. Therefore, a vent pipe and a vent valve are usually added to the top of the tank. When oil is poured into the tank, the vent valve is opened to release the gas in the tank, so that the industrial oil can flow into the tank smoothly.

[0003] Since the mixed oil itself may contain volatile toxic aromatic hydrocarbons such as benzene, toluene, and xylene, these substances volatilize into gases and are discharged through the exhaust device. Moreover, the mixed oil may undergo chemical reactions such as oxidation and polymerization during long-term storage, generating new toxic substances such as hydrogen sulfide, aldehydes, and ketones. Directly discharging such harmful gases into the external environment will cause pollution, and the inhalation of these harmful gases by workers will cause serious harm to their health. Based on the above problems, this application proposes an exhaust device for industrial-grade mixed oil storage tanks. Utility Model Content

[0020] 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.

[0021] Reference Figure 1-5An exhaust device for an industrial-grade mixed oil storage tank includes a storage tank 1, a filter box 2 fixedly mounted on the top of the storage tank 1, a rotating assembly 3 inside the filter box 2, and a rotating sealing plate 4 overlapping inside the storage tank 1. The side of the rotating sealing plate 4 closest to the inside of the filter box 2 is arc-shaped. The rotating sealing plate 4 is made of metal, allowing it to fit more closely to the filter box 2, thus sealing and preventing gas from entering its right side. Placement assemblies 5 are provided on both sides of the rotating sealing plate 4. The filter box 2 includes a worm gear 31 rotatably mounted inside the filter box 2, a handle 32 fixedly mounted at the front end of the worm gear 31, a worm wheel 33 meshing with the surface of the worm gear 31, a rotating shaft 34 fixedly mounted inside the worm wheel 33, and a rotating shaft 34 fixedly mounted at its top end. At the bottom of the sealing plate 4, a fixed seat 35 is installed at the bottom end of the rotating shaft 34 via a bearing. The fixed seat 35 is fixedly installed inside the filter box 2. The handle 32 drives the worm gear 33 to rotate, so that the worm gear 33 drives the rotating sealing plate 4 to rotate via the rotating shaft 34, so that the positions of the left and right placement components 5 of the rotating sealing plate 4 are interchanged, thereby avoiding the inability to adsorb gas after the adsorbent is saturated. Moreover, during use, the adsorbent can be quickly rotated and replaced, so that the mixed oil delivery does not need to be interrupted. A sealing cover 6 is provided on the top of the filter box 2. An air inlet pipe 7 is fixedly provided on the left side of the filter box 2. The air inlet end of the air inlet pipe 7 is connected to the top of the liquid storage tank 1. An oil inlet pipe 8 is fixedly provided on the top of the liquid storage tank 1. An oil outlet pipe 9 is fixedly provided on the bottom of the liquid storage tank 1. Control valves are fixedly installed on both the oil inlet pipe 8 and the oil outlet pipe 9.

[0022] Specifically, the sealing cover 6 includes a fixed cover 61 fixedly installed on the top of the filter box 2. An exhaust pipe 62 is fixedly installed on the top of the fixed cover 61. A connecting groove 63 is opened on the right side of the fixed cover 61, and a connecting block 64 is overlapped inside the connecting groove 63. A movable cover 65 is fixedly installed on the right side of the connecting block 64. The movable cover 65 is installed on the top of the filter box 2 by bolts. The placement assembly 5 includes placement boxes 51 fixedly installed on the left and right sides of the rotating sealing plate 4. An installation groove 52 is opened on the top of the placement box 51, and a fixing magnet 53 is fixedly installed inside the installation groove 52. A box cover 54 is overlapped on the top of the placement box 51. There are two installation grooves 52 and two fixing magnets 53. The two installation grooves 52 are an arc-shaped groove and a rectangular groove, and the two fixing magnets 53 are an arc-shaped magnet and a rectangular magnet, respectively. The arc-shaped and rectangular magnets can be installed through the arc-shaped and rectangular grooves, and the arc-shaped and rectangular magnets attract the box cover 54, making the box cover 54 more stable after installation. Circular holes are provided through the top of the box cover 54 and the lower side wall of the placement box 51. The filter box 2 has several circular holes to facilitate gas entry and exit. The cover 54 is attracted to the fixed magnet 53. A handle 55 is fixedly installed on the top of the cover 54. By removing the bolt from the movable cover 65 and pulling it to the right, the movable cover 65 moves the connecting block 64 out of the connecting groove 63, allowing the movable cover 65 to be removed from the top of the filter box 2. Pulling the handle 55 moves the cover 54 upwards, separating it from the fixed magnet 53. The filter box 54 can then be placed... Remove the used adsorbent from the filter box 2 and replace it with unused adsorbent. Place the lid 54 on top of the placement box 51 using the handle 55 and attach the lid 54 to the top of the placement box 51 using the fixing magnet 53. Place the movable cover 65 on top of the filter box 2 so that the connecting block 64 is inserted into the connecting groove 63. Fix the movable cover 65 to the top of the filter box 2 using bolts. This facilitates the replacement of the adsorbent and prevents the gas from being unable to be adsorbed after the adsorbent is saturated.

[0023] In use: Connect the external oil pipeline to the oil inlet pipe 8. The mixed oil is delivered to the storage tank 1 through the oil inlet pipe 8. The gas inside the storage tank 1 moves upward under the push of the mixed oil and enters the filter box 2 through the air inlet pipe 7. Then it enters the placement box 51 through the circular hole. The gas is filtered by the adsorbent in the placement box 51, which absorbs the harmful gases in the gas. The filtered gas is discharged from the placement box 51 through the circular hole on the handle 55. Finally, the filtered gas is discharged to the outside through the exhaust pipe 62. When the adsorbent in the placement box 51 is full, the worm 31 is rotated by the handle 32. The worm 31 drives the worm wheel 33, which is meshed with it, to rotate. The worm wheel 33 drives the rotating shaft 34 to rotate inside the fixed seat 35 through the bearing. The rotating shaft 34 drives the rotating sealing plate 4 to rotate, so that the positions of the left and right placement components 5 of the rotating sealing plate 4 are interchanged. The discharged gas is filtered by the unused adsorbent.
