Detailed Description
The present application is described in further detail below with reference to figures 1-2.
The embodiment of the application discloses liquefied natural gas storage tank convenient to cooling. Referring to fig. 1, the liquefied natural gas storage tank includes a tank body 1, and a plurality of cooling ring covers 2 have been cup jointed to the lateral wall of tank body 1, and a plurality of cooling ring covers 2 are along tank body 1's length direction align to grid. An opening is formed in the inner side of the circle, close to the tank body 1, of the cooling ring cover 2, and the opening of the cooling ring cover 2 is fixedly connected with the outer side wall of the tank body 1. The bottom end of the tank body 1 is fixedly connected with four supporting legs 11 supported on the ground.
All be connected with connecting pipe 3 between the adjacent cooling ring cover 2, one side of jar body 1 is equipped with storage water tank 4, and the fixed intercommunication of a side of storage water tank 4 has pump water pipe 41, and pump water pipe 41 keeps away from the one end of storage water tank 4 and is located the fixed intercommunication of cooling ring cover 2 of jar body 1 top. The water pump 44 is installed on the water pumping pipe 41, a water return pipe 42 is fixedly communicated with one side surface of the water storage tank 4 far away from the water pumping pipe 41, and one end of the water return pipe 42 far away from the water storage tank 4 is fixedly communicated with the cooling ring cover 2 located at the lowest end of the tank body 1.
When the tank body 1 needs to be cooled, the water pump 44 is started, so that the water in the water storage tank 4 enters the interior of the cooling ring cover 2 at the uppermost end of the tank body 1 along the water pumping pipe 41. Since the adjacent cooling ring covers 2 are communicated with each other through the connection pipe 3, the water flows through the inside of each cooling ring cover 2 and finally flows back to the inside of the water storage tank 4 along the water return pipe 42. The water in the cooling ring cover 2 contacts the outer side wall of the tank body 1, so that the tank body 1 can be cooled.
The adjacent connecting pipes 3 are respectively positioned at two sides of the tank body 1, and the axes of the adjacent connecting pipes 3 are not positioned on the same straight line. Therefore, when water in one cooling ring cover 2 flows into the adjacent cooling ring cover 2 along the connecting pipe 3, the water can enter the connecting pipe 3 only by the distance of one end flowing in the cooling ring cover 2, and the situation that the water which just enters the cooling ring cover 2 immediately enters the next cooling ring cover 2 along the connecting pipe 3 is reduced.
The upper surface of the cooling ring cover 2 is provided with a plurality of through holes 21, so that rainwater can enter the cooling ring cover 2 through the through holes 21 in rainy days; finally, rainwater enters the water storage tank 4 along the water return pipe 42 to be collected, and the rainwater is fully utilized.
The upper surface of the cooling ring cover 2 is gradually inclined downwards towards the direction close to the tank body 1, so that rainwater can fall on the upper surface of the cooling ring cover 2 and penetrate through the through hole 21 to enter the cooling ring cover 2.
Referring to fig. 1 and 2, the upper surface of the water storage tank 4 is open, and a door 43 for sealing the opening of the water storage tank 4 is fastened to the opening of the water storage tank 4. The inside filter 5 that can dismantle of storage water tank 4 is connected with, and wet return 42 is located the top of filter 5 with the junction of storage water tank 4, and the pump water pipe 41 is located the below of filter 5 with the junction of storage water tank 4.
When the rainwater flowed into storage water tank 4 inside along wet return 42, filter 5 can filter the rainwater, and the rainwater after filtering is gone into cooling ring cover 2 inside along pump water pipe 41 pump, has reduced the condition emergence of impurity jam pump water pipe 41 in the rainwater.
Two inner side walls of the water storage tank 4 are respectively and fixedly connected with a lapping rod 6, and the filter plate 5 is lapped on the two lapping rods 6. When needs clear up filter 5, the pulling door body 43 makes a body 43 break away from storage water tank 4, and then to keeping away from the direction pulling filter 5 of overlap joint pole 6, make filter 5 break away from inside storage water tank 4, be convenient for clear up filter 5.
Two ends of the filter plate 5 are respectively and fixedly connected with a group of elastic suckers 51, and the number of the suckers 51 in the group of suckers 51 is two. The suction cup 51 is attached to the upper surface of the lapping rod 6, reinforcing the connection between the filter plate 5 and the lapping rod 6.
The implementation principle of a liquefied natural gas storage tank convenient to cool down of the embodiment of this application is: when the tank body 1 needs to be cooled, the water pump 44 is started, so that water in the water storage tank 4 enters the cooling ring cover 2 positioned at the uppermost end of the tank body 1 along the water pumping pipe 41, and the water flows back to the inside of the water storage tank 4 along the water return pipe 42 after passing through each cooling ring cover 2. The water in the cooling ring cover 2 cools the tank body 1.
When the weather is rainy, rainwater passes through the through holes 21 and enters the interior of the cooling ring cover 2, and the rainwater flows through each cooling ring cover 2 and then enters the interior of the water storage tank 4 along the water return pipe 42 for collection.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
