Description

Technical Field

[0001] The utility model relates to the technical field of storage tanks, in particular to a storage tank. Background Art

[0002] Storage tanks are used to store refined chemicals such as acids, alkalis, alcohols, gases, and liquids. When storage tanks are located in coastal areas or areas with high solar radiation, solar radiation will cause the temperature of the tank top to rise. In order to reduce the impact of solar radiation on the temperature of the tank, a cooling spray ring is usually installed on the tank top. Therefore, when the temperature inside the tank rises, the spray ring is started to spray cooling water to cool the tank top. However, after long-term use of the tank, there will be a lot of oil on the tank top. The sprayed cooling water or rainwater will form oily wastewater after passing through the tank top, which will flow irregularly downward along the tank wall, forming oil stains on the surface of the tank wall, affecting the appearance of the tank and increasing the cost of tank cleaning. In addition, the oily wastewater flows irregularly in the cofferdam of the tank area, which is not conducive to the collection of wastewater. Usually, an oil film is formed in the low-lying area of ​​the tank floor, posing a safety hazard. Utility Model Content

[0028] See also Figure 1The embodiment of the present application provides a storage tank 1, comprising a tank body 100, a water collecting tank 200 and a water diversion pipe 300. The tank body 100 is used to store chemicals, and comprises a tank wall 110 and a tank top 120 arranged on the top of the tank wall 110. The water collecting tank 200 is arranged around the tank wall 110 and is spaced from the tank top 120. One end of the water diversion pipe 300 is connected to the water collecting tank 200, and the other end is connected to a sewage treatment facility. The water diversion pipe 300 is used to deliver oily sewage to the sewage treatment facility to achieve rainwater and sewage separation.

[0029] The present application provides a storage tank 1, in which the water collecting trough 200 is arranged around the tank wall 110 and is spaced apart from the tank top 120. Therefore, the oily wastewater formed after the cooling water or rainwater of the spray pipe 10 passes through the tank top 120 will flow into the water collecting trough 200 along the tank top 120 and the tank wall 110, and will not form oil stains on the surface of the tank wall 110, thereby ensuring the aesthetics of the storage tank 1; because one end of the water diversion pipe 300 is connected to the water collecting trough 200 and the other end is arranged in the sewage treatment facility, the oily wastewater in the water collecting trough 200 will directly enter the sewage treatment facility through the water diversion pipe 300, and will not form an oil film in the low-lying area of ​​the tank area floor, thereby reducing safety hazards and the pollution of the tank wall and the tank area by the oily wastewater.

[0030] It should be noted that the tank top 120 is arranged at an angle, so cooling water or rainwater can flow into the tank wall 110 along the tank top 120 , and then flow into the water collecting tank 200 from the tank wall 110 .

[0031] In some embodiments, see Figure 1 and Figure 2 The water collecting trough 200 includes a first reinforcement member 210, a transition member 220 and a water retaining member 230. The first reinforcement member 210 is connected to the tank wall 110. The transition member 220 is connected and arranged between the first reinforcement member 210 and the water retaining member 230. The transition member 220 and the water retaining member 230 are arranged at an angle.

[0032] The first reinforcement member 210 can ensure the overall strength of the water collection tank 200, the water retaining member 230 is used to prevent the oily sewage with a high flow rate from splashing out of the water collection tank 200 when flowing into the water collection tank 200 along the inclined tank top 120, and the transition member 220 is used for the transition between the first reinforcement member 210 and the water retaining member 230. Specifically, the first reinforcement member 210, the transition member 220 and the water retaining member 230 are all welded to ensure the structural strength, the transition member 220 and the water retaining member 230 are both plate-shaped structures, the transition member 220 and the water retaining member 230 can be vertically arranged, and the height of the water retaining member 230 can be 250 mm.

[0033] In some embodiments, the water guide pipe 300 is connected to the transition piece 220 .

[0034] Since the first reinforcement 210 is used to strengthen the overall strength of the water collection tank 200, if the water diversion pipe 300 is connected to the first reinforcement 210, it is necessary to open a hole in the first reinforcement 210, which will weaken the strength of the water collection tank 200. Therefore, the water diversion pipe 300 can be connected to the transition piece 220.

[0035] In some embodiments, the first reinforcement member 210 includes a first reinforcement plate 211 and a second reinforcement plate 212 that are arranged at an angle, the first reinforcement plate 211 is connected to the tank wall 110 , and the second reinforcement plate 212 is connected to the transition member 220 .

[0036] The first reinforcing plate 211 and the second reinforcing plate 212 can be arranged vertically, and the first reinforcing plate 211 is arranged below the second reinforcing plate 212, that is, the tank wall 110, the second reinforcing plate 212, the transition piece 220 and the water retaining piece 230 together form a groove structure for accommodating the oily sewage flowing down from the tank top 120, and the first reinforcing plate 211 can play a certain supporting role for the oily sewage. Specifically, the first reinforcing member 210 can be an angle steel ring.

[0037] In some embodiments, the upper portion of the first reinforcement member 210 is continuously and hermetically welded to the tank wall 110 , and the lower portion of the first reinforcement member 210 is intermittently welded to the tank wall 110 .

[0038] The upper portion of the first reinforcement 210 is continuously and sealingly welded to the tank wall 110 to prevent the liquid in the sump 200 from leaking along the tank wall 110. The lower portion of the first reinforcement 210 is intermittently welded to the tank wall 110 to prevent the first reinforcement 210 from being deformed due to welding stress when the upper end of the first reinforcement 210 is continuously welded to the tank wall 110, resulting in an uneven upper edge.

[0039] In some embodiments, the sump 200 further includes a plurality of second reinforcement members 240 spaced apart along the circumference of the tank wall 110 , and the second reinforcement members 240 are connected to both the first reinforcement member 210 and the transition member 220 .

[0040] The second reinforcement member 240 can be a reinforcement rib plate, which is used to strengthen the bearing capacity of the rainwater and sewage collection tank. Specifically, the circumferential interval between two adjacent second reinforcement members 240 is less than or equal to 1 meter, so as to ensure that when there is a certain liquid level in the water collection tank 200, the water collection tank 200 can maintain a level and the liquid flows smoothly.

[0041] In some embodiments, in order to improve the discharge efficiency of oily wastewater, at least two water diversion pipes 300 are provided, and the circumferential interval between two adjacent water diversion pipes 300 is less than or equal to 10 meters.

[0042] In some embodiments, the distance between the water collecting groove 200 and the tank top 120 is greater than or equal to 3 times the thickness of the tank wall 110 to reduce the mutual influence between the welding stress of the first reinforcement 210 and the welding thermal stress of the tank top 120. Specifically, the corner water collecting groove 200 is set at 50mm to 80mm from the top of the tank wall 110.

[0043] In some embodiments, the storage tank 1 further includes a heat-insulating layer 20 , which is disposed around the tank wall 110 and below the water collecting tank 200 , and the heat-insulating layer 20 is spaced apart from the water diversion pipe 300 .

[0044] Since the insulation layer 20 is surrounded by the tank wall 110 and disposed below the water collecting tank 200, the water collecting tank 200 can also serve as a rain cap on the top of the insulation tank, and the insulation layer 20 and the water diversion pipe 300 are spaced apart to facilitate the installation of the connecting flange on the water diversion pipe 300. Specifically, the spacing between the insulation layer 20 and the water diversion pipe 300 needs to be greater than or equal to 30 mm.

[0045] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0046] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
