Description

Technical Field

[0001] This utility model relates to the field of crude liquid ammonia technology, specifically to an oil removal and purification device for crude liquid ammonia. Background Technology

[0002] Crude liquid ammonia refers to liquid ammonia that has not been deeply purified. It usually contains impurities such as oil, water, sulfides, and dust. It mainly comes from synthetic ammonia production, coking by-products, or industrial recycling processes. It needs to undergo purification treatments such as oil removal, dehydration, and desulfurization to meet industrial or electronic grade standards for use in refrigeration, chemical synthesis, or fuel cells. Therefore, an oil removal and purification device for crude liquid ammonia is needed.

[0003] Although existing technologies for oil removal and purification equipment for crude liquid ammonia have many beneficial effects, the following problems still exist: In actual use, traditional crude liquid ammonia purification usually requires the addition of a chemical neutralizing agent under suitable conditions and temperature, followed by uniform mixing to achieve the purpose of purification. However, the required processing capacity of crude liquid ammonia varies, and the required stirring frequency is also different. Furthermore, during the stirring and mixing process, grease tends to accumulate on filter plates and other locations, requiring additional cleaning. Long-term accumulation can interfere with subsequent processing. Utility Model Content

[0024] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0025] This utility model provides an overall structural schematic diagram of an embodiment of an oil removal and purification device for crude liquid ammonia, including: Please see Figures 1-5 This utility model provides a technical solution: See also Figure 1 Figure 2 As shown, an oil removal and purification device for crude liquid ammonia includes a housing 1 and a discharge port 4 opened at the bottom of the housing 1. The housing 1 is equipped with a drive assembly 5, a rotating assembly 6 is provided on one side of the drive assembly 5, and an oil scraping assembly 7 is provided at the bottom of the rotating assembly 6. While the drive assembly 5 drives the rotating assembly 6 to rotate through a drive motor, the auxiliary rod 56 drives the stirring plate 65 to rotate in the inner barrel 9, and the inner barrel 9 rotates on the inner wall of the housing 1, driving the oil scraping assembly 7 to move horizontally, thereby achieving the effect of oil scraping during the mixing and purification process of crude liquid ammonia.

[0026] See also Figure 3As shown, the drive assembly 5 includes a drive rod 51, a square box 53 is fitted onto the outer circumference of the drive rod 51, a track 52 is fitted inside the square box 53, an auxiliary rod 56 is fitted onto the inner wall of the track 52, a gear 54 is fitted onto the top of the outer circumference of the drive rod 51, a gear ring 55 is meshed with the surface of the gear 54, an inner barrel 9 is bolted to the inner wall of the gear ring 55, a track 57 is fitted onto the bottom of the outer circumference of the drive rod 51, and a driven rod 58 is fitted onto the inner wall of the track 57.

[0027] See also Figure 3 and Figure 4 As shown, the rotating component 6 includes an inner barrel 9. A horizontal block 63 is bolted to the top of the inner barrel 9. A horizontal groove 64 is provided on the top of the inner circumference of the box body 1. The horizontal block 63 is slidably connected to the horizontal groove 64.

The locking block 61 is slidably connected to the locking groove 62. A stirring plate 65 is provided on the outer circumference of the auxiliary rod 56. Under the drive of the driving component 5, the auxiliary rod 56 drives the stirring plate 65 to rotate in the inner barrel 9. At the same time, the inner barrel 9 also rotates on the inner wall of the box body 1, thereby achieving a double rotation effect and accelerating the purification process of crude liquid ammonia.

[0028] See also Figure 4 and Figure 5 As shown, the oil scraping assembly 7 includes a second gear 71, a driven rod 58 sleeved on the inner circumference of the second gear 71, a third gear 72 meshing with the surface of the second gear 71, a crossbar 74 sleeved at one end of the third gear 72, a slider 75 slidably connected to the outer circumference of the crossbar 74, and a scraper 77 bolted to one end of the slider 75. Under the drive of the drive assembly 5, the second gear 71 and the third gear 72 mesh and rotate directly, causing the slider 75 to drive the scraper 77 to move on the inner wall of the groove 79, so that the top of the scraper 77 contacts the filter screen 10, thereby achieving the purpose of scraping oil.

[0029] See also Figure 4 and Figure 5 As shown, a filter screen 10 is bolted to the inner circumference of the outlet 4. A groove 79 is provided on the inner circumference of the outlet 4 below the filter screen 10. A brush 78 is bolted to the inner wall of the groove 79. The filter screen 10 facilitates the filtration of grease in the crude liquid ammonia, causing it to condense on the top of the filter screen 10, which is then cleaned in conjunction with the scraper 77.

[0030] See also Figure 5 As shown, a groove 76 is provided on one side of the groove 79. The inner wall of the groove 76 is slidably connected to the slider 75, which facilitates translation on the outer circumference of the crossbar 74, thereby maintaining balance during the movement of the scraper 77.

[0031] See also Figure 1 and Figure 2 As shown, the top of the box 1 is provided with a feed inlet 2. The inner circumference of the feed inlet 2 is connected to a diversion plate 3 by bolts. The diversion plate 3 facilitates the separate addition of crude liquid ammonia and the chemical agents required in the preparation process, so as to maintain the purity of both.

The content protected by this utility model does not involve any improvement to the internal structure and method.

[0036] Combination Figures 1-5 The specific usage process of the oil removal and purification equipment for crude liquid ammonia according to this embodiment is as follows: 1. In actual use, after the operator moves the container 1 to a suitable position, the crude liquid ammonia to be processed is added through the feed inlet 2. The diverter plate 3 separates the crude liquid ammonia from the chemical agents required for the processing. The drive motor causes the drive assembly 5 to start operating, that is, the drive rod 51 rotates. As a result, the gear 54 meshes with the gear ring 55. With the locking block 61 slidingly connected to the locking groove 62 and the cross block 63 slidingly connected to the cross groove 64, the inner barrel 9 can rotate inside the container 1. During the rotation of gear 54, track 52 drives auxiliary rod 56 to rotate synchronously with gear 54, so that stirring plate 65 can rotate in the opposite direction inside inner barrel 9. At the same time, track 57 drives driven rod 58 to rotate, so gear 72 can mesh with gear 71 on the outer circumference of driven rod 58, so that slider 75 can drive scraper 77 to move in translation on the inner wall of groove 76 and groove 79 respectively, thereby achieving the effect of scraping oil from filter screen 10 during stirring and rotation.

[0037] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
