A differential pressure densitometer consists of two manometers, mounted at either end of the device, to measure the static pressure at different locations.

[0031] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4The utility model provides an acid density measuring device, comprising:

[0032] Support frame 1, on which a density measuring mechanism 2 is provided. It should be noted that the density measuring mechanism 2 is used to measure the density of the acid solution;

[0033] The density measuring mechanism 2 includes a storage protection box 201, a vertical rod 202, a pressure gauge 203, a sleeve plate 204, a pressure gauge 205, a vertical rod 206, a threaded barrel 207, a screw 208 and a connecting plate 210;

[0034] The storage protection box 201 is fixedly installed on the support frame 1, the vertical pole 1 202 and the vertical pole 206 are both vertically slidably installed on the storage protection box 201, the pressure gauge 1 203 is fixedly installed on the vertical pole 1 202, the sleeve 204 is fixedly connected to the pressure gauge 2 205 and the connecting plate 210, the top of the connecting plate 210 is fixedly connected to the threaded barrel 207, the threaded barrel 207 is vertically slidably installed on the vertical pole 206, the screw 208 is threadedly connected to the threaded barrel 207, and the screw 208 is rotatably installed on the vertical pole 206.

[0035] By rotating the screw 208 through the density measuring mechanism 2, the threaded barrel 207 can be moved vertically, and the sleeve plate 204 drives the pressure gauge 2 205 to move, so that the distance between the pressure gauge 1 203 and the pressure gauge 2 205 can be adjusted conveniently, and the average density at different heights can be measured conveniently.

[0036] Specifically, the density measuring mechanism 2 also includes a pull rod 211 and a controller 212. The pull rod 211 is fixedly installed between the vertical pole 1 202 and the vertical pole 2 206. The controller 212 is fixedly installed on the side of the storage protection box 201. The controller 212 is electrically connected to the pressure gauge 1 203 and the pressure gauge 2 205.

[0037] By using the density measuring mechanism 2, the pull rod 211 is moved downward, so that the pressure gauge 1 203 and the pressure gauge 2 205 are moved into the acid solution, and the pressure value is sent to the controller 212, so that the density of the acid solution can be measured and processed.

[0038] Specifically, the density measuring mechanism 2 also includes a limiting shaft 213 and a tightening block 214. The limiting shaft 213 is fixedly installed on the bottom of the storage protection box 201, and the tightening block 214 is rotatably sleeved on the outside of the limiting shaft 213. A damping pad is embedded in the top of the tightening block 214, and the damping pad is in contact with the vertical rod 202.

[0039] Through the above-mentioned density measuring mechanism 2, the pressure gauge 1 203 and the pressure gauge 2 205 are moved into the storage protection box 201, and the tightening block 214 is rotated so that the damping pad on the tightening block 214 abuts against the vertical rod 1 202.

It should be noted that the density of the acid liquid in the acid liquid placement cup 4 can be measured by the density measuring mechanism 2.

This makes it easy to adjust the distance between the first pressure gauge 203 and the second pressure gauge 205, and to measure the average density at different heights.

[0045] S2: Move the pull rod 211 downward so that the pressure gauge 1 203 and the pressure gauge 2 205 are moved into the acid solution. The pressure value is sent to the controller 212, and the density of the acid solution can be measured and processed. The operation is relatively simple.

[0046] S3: Move the pressure gauge 1 203 and the pressure gauge 2 205 into the storage protection box 201, rotate the tightening block 214 so that the damping pad on the tightening block 214 abuts against the vertical pole 1 202, so that the vertical pole 1 202 can be limited, and it is convenient to store it after use. The damping pad can provide greater friction to ensure the stability of the position.
