Embodiment Construction
[0027] Below in conjunction with accompanying drawing, the present invention will be further described:
[0028] figure 1 A schematic structural view of a large-capacity concentrated sulfuric acid metering device is shown, including a metering tank 1 , a load cell 2 , a safety buttress 3 and a support beam 4 . There are four safety buttresses 3, which are placed on the ground, and the four safety buttresses 3 are arranged at 90 degrees successively to form fan blades. With the safety pier 3 as the base, the metering tank 1 is placed on the safety pier 3 through the support beam 4 , and a load cell 2 is arranged between the support beam 4 and the safety pier 3 .
[0029] The metering tank 1 is a large-capacity flat-bottomed metering tank with a capacity greater than or equal to 300 tons. The top of the metering tank 1 is provided with an acid inlet 11, and the side of the metering tank 1 near the bottom is provided with an acid outlet. The acid outlet is provided with an acid ...

The invention relates to a large-capacity concentrated sulfuric acid metering device comprising a metering pot (1), wherein the metering pot (1) is a large-capacity flat-bottom metering pot with the capacity which is not less than 300 tons; the metering pot (1) is placed on a safety support; and a weighing sensor (2) is arranged between the metering pot (1) and the safety support. The safety support comprises four safety support piers (3) which are uniformly distributed along the circumference of the metering pot (1); each safety support pier (3) is of a multi-grade step structure; and an anti-falling step structure (32) and anti-sideslip step structure (31) guarantee that the metering pot (1) neither sideslips nor inclines. An acid feeding opening (11) is arranged at the top of the metering pot (1); an acid discharging opening is arranged on the side face of the metering pot (1), which is close to the bottom; the acid discharging opening is provided with an acid discharging valve (12); and the metering pot (1) is not connected with an acid feeding / discharging pipeline to guarantee metering precision. A supporting beam (4) is further arranged between the bottom of the metering pot (1) and each safety support pier (3). The large-capacity concentrated sulfuric acid metering device is simple in structure, high in safety and high in metering efficiency.
Description
technical field [0001] The invention belongs to the metering field of concentrated sulfuric acid, in particular to a large-capacity concentrated sulfuric acid metering device. Background technique [0002] At present, the main metering methods of concentrated sulfuric acid are as follows: [0003] 1. The geometric scale measurement method is the method of measuring with a liquid level gauge. This method is to measure the one-to-one relationship between the liquid level height of concentrated sulfuric acid in the metering tank and the volume in the tank, and then through calculation, that is, the volume of concentrated sulfuric acid Multiply by the density of concentrated sulfuric acid to get the weight of concentrated sulfuric acid. [0004] 2. The method of flow measurement is to install a flow meter or a metering pump on the pipeline, and calculate the weight of the concentrated sulfuric acid by measuring the flow rate and capacity of the concentrated sulfuric acid flowin...
