Description

Technical Field

[0001] The utility model belongs to the technical field of heat transfer oil dehydration, in particular to a heat transfer oil dehydration exhaust tank. Background Art

[0002] Thermal oil is a kind of special oil with good thermal stability used for indirect heat transfer. It has been widely used in various occasions in recent years because of its uniform heating, accurate temperature control, ability to generate high temperature under low vapor pressure, good heat transfer effect, energy saving, convenient transportation and operation, etc., and its uses and usage are increasing. In the production process of thermal oil, the staff needs to use a dehydration exhaust tank to remove the moisture in the thermal oil to avoid a large amount of water in the thermal oil. When the thermal oil enters the hot coal system, the water will evaporate and expand instantly to form a steam-water mixture, resulting in system tank expansion, oil overflow, impact and other phenomena.

[0003] However, there are some problems with the existing technology: the existing dehydration exhaust tank heats the heat transfer oil to evaporate the water in the heat transfer oil and discharge it outward. However, during the exhaust process, the evaporated water will condense when it contacts the top of the inner wall of the exhaust tank, causing part of the water to condense into water droplets and then drip into the heat transfer oil, thereby reducing the dehydration efficiency of the heat transfer oil. Therefore, we propose a heat transfer oil dehydration exhaust tank. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a heat transfer oil dehydration exhaust tank, which can collect condensed water droplets by scraping them off, thereby preventing the water droplets from falling into the heat transfer oil and affecting the dehydration efficiency.

[0006] Optionally, the annular groove is inclined, and a curved pipe is fixedly connected to the bottom of the annular groove, and the other end of the curved pipe extends to the outside of the heating tank.

[0009] Optionally, there are two exhaust pipes, the two exhaust pipes are symmetrically distributed, and a filter plate is fixedly installed on the top of the exhaust pipe.

[0010] Optionally, the pad strip has an arc-shaped appearance, and the curvature of the pad strip is the same as the curvature of the top of the inner wall of the heating tank.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 6 As shown, a heat transfer oil dehydration exhaust tank provided by an embodiment of the utility model includes a heating tank 1 and an exhaust pipe 9, the exhaust pipe 9 is fixedly connected to the heating tank 1, a driving motor 2 is fixedly installed on the top of the heating tank 1, the output shaft of the driving motor 2 is fixedly sleeved with a rotating shaft 3, and the bottom end of the rotating shaft 3 extends to the interior of the heating tank 1, a scraper 4 is fixedly installed on the top of the outer surface of the rotating shaft 3, a guide groove 5 is fixedly installed on the scraper 4, a conduit 7 is fixedly connected to the guide groove 5, a pad 6 is also fixedly installed on the scraper 4, the pad 6 is attached to the top of the inner wall of the heating tank 1, and an annular groove 8 located below the scraper 4 is fixedly installed on the inner wall of the heating tank 1.

[0023] Furthermore, the annular groove 8 is inclined, and a curved pipe 10 is fixedly connected to the bottom of the annular groove 8 , and the other end of the curved pipe 10 extends to the outside of the heating tank 1 .

[0024] By arranging the elbow 10 on the lower side of the bottom of the annular groove 8 , the water flow in the annular groove 8 can flow along the inclined inner cavity of the annular groove 8 to the inside of the elbow 10 and finally flow out from the elbow 10 .

[0025] Furthermore, a frame 11 located below the curved pipe 10 is fixedly mounted on the outer wall of the heating tank 1 , and a square box 12 is movably mounted in the inner cavity of the frame 11 .

[0026] The water flowing out of the elbow 10 can be gathered inside the square box 12, and the staff can remove the square box 12 to process the collected water.

[0027] Furthermore, stirring blades 13 are fixedly mounted on the bottom of the outer surface of the rotating shaft 3 , and the stirring blades 13 are evenly distributed on the bottom of the outer surface of the rotating shaft 3 .

[0028] Through the design of the stirring blade 13, when the driving motor 2 is running so that the shaft 3 drives the stirring blade 13 to rotate, the heat transfer oil in the heating tank 1 can be stirred, so that the heat transfer oil is heated more evenly, thereby improving the dehydration effect.

[0029] Furthermore, there are two exhaust pipes 9 , which are symmetrically distributed, and a filter plate 14 is fixedly installed on the top of the exhaust pipe 9 .

[0030] The design of the filter plate 14 can prevent external dust and impurities from entering the heating tank 1 and affecting the quality of the heat transfer oil.

[0031] Furthermore, the pad strip 6 has an arc-shaped appearance, and the curvature of the pad strip 6 is the same as the curvature of the top of the inner wall of the heating tank 1 .

[0032] The pad strip 6 can be made of high temperature resistant silicone. Since silicone has good elasticity, the pad strip 6 can fit tightly against the inner wall of the heating tank 1, thereby maintaining a good scraping effect on water drops on the inner wall of the heating tank 1.

[0033] During use, the staff adds heat transfer oil into the heating tank 1 to heat it. The water in the heat transfer oil evaporates due to the heat and flows upward, and is discharged outward from the exhaust pipe 9 through the top of the inner wall of the heating tank 1. Part of the water will condense on the top of the inner wall of the heating tank 1. The staff can start the drive motor 2 to make the rotating shaft 3 drive the scraper 4 and the pad 6 to rotate, and the condensed water droplets will be hung down and flow to the inside of the guide groove 5, and finally flow from the conduit 7 to the inside of the annular groove 8. Since the annular groove 8 is inclined, the water flow converges above the bend 10 and flows from the bend 10 to the inside of the square box 12, so as to prevent water droplets from dripping into the heat transfer oil and affecting the dehydration efficiency. At the same time, due to the rotation of the rotating shaft 3, the stirring blade 13 will be driven to rotate together, so that the heat transfer oil can be stirred, so that the heat transfer oil is heated more evenly to improve the dehydration effect.

[0034] The above embodiments are only used to help understand the method and core idea of ​​the utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made to the utility model without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
