Description

Technical Field

[0001] The utility model belongs to the technical field of salt field brine detection, and in particular relates to a Baume meter with accurate measurement. Background Art

[0002] Salt production is the production of table salt (or industrial salt). The salt industry occupies an important economic position in the national economy and is an important part of the national economy. Salt is a necessity for human life and a basic raw material for the chemical industry. It is also widely used in other industrial sectors and agriculture, animal husbandry and fishery. Salt tax was once an important fiscal revenue for many countries. The total proven salt resource reserves in the world are about 64 million tons, of which the salt content of seawater (including seabed sediments) is 43 million tons, rock salt is 21 million tons, and salt lakes and underground natural brine are 310 billion tons. New rock salt deposits are still being discovered.

[0003] Baume meter, also known as Baume hydrometer, is a method of measuring solution concentration and density in degrees Baume. The Baume meter is used in the process of brine detection. Referring to the announcement number CN207923184U, an online detection device for salt-making brine is provided with a Baume hydrometer in the detection unit during the detection of brine. When the brine is detected, the detection head of the Baume hydrometer will be immersed in the brine. Due to the high salt content in the brine, salt scale will be deposited on the detection head during the immersion process. If it is not cleaned, it will affect the detection result of the Baume meter, thereby causing errors in the detection result. Utility Model Content

DETAILED DESCRIPTION

[0019] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1

[0021] like Figure 1 - Figure 5As shown, a Baume meter with accurate measurement includes a buoyancy box 1 and a working box 2 installed on the inner wall of the top of the buoyancy box 1. A fixing plate 5 is provided inside the working box 2. A detection mechanism is installed at the bottom of the fixing plate 5. The detection mechanism includes a Baume detection body 6 installed at the bottom of the fixing plate 5, a mounting rod 19 installed at the bottom of the Baume detection body 6, and a detection head 17 installed at the bottom of the mounting rod 19. Two sets of driving mechanisms are installed on the top of the working box 2 to make the fixing plate 5 move up and down. The driving mechanism includes a pneumatic cylinder 3 installed on the top of the working box 2 and a connecting plate 4 installed at the output end of the pneumatic cylinder 3. The driving mechanism is not only convenient for moving the detection head 17 into the cleaning box 10, but also when the detection mechanism needs to be repaired, the driving mechanism will drive the detection mechanism to move upward. At this time, the detection head 17 will pass through the first opening and move to the outside of the working box 2, so as to facilitate its maintenance. The bottom of the connecting plate 4 is fixedly connected to the top of the fixing plate 5, and the bottom inner wall of the working box 2 is equipped with a cleaning box 10 and a water tank 11 with an annular structure and a cover arranged outside the cleaning box 10, and the cleaning box 10 is rotatably connected to the working box 2. The top of the cleaning box 10 is provided with a first opening, and the inside of the cleaning box 10 is equipped with a cleaning mechanism for cleaning the detection mechanism. The cleaning mechanism comprises a cleaning sponge 18 mounted on the inner wall of one side of the cleaning box 10, one side of the cleaning sponge 18 is in contact with the outside of the detection head 17, a water cavity 16 is provided inside the cleaning box 10, and a plurality of nozzles 15 are mounted on the inner wall of the cleaning box 10 and connected to the water cavity 16. A rotating mechanism for driving the cleaning box 10 to rotate is installed inside the working box 2. The rotating mechanism comprises a mounting plate 13 mounted on the inner wall of the working box 2, a rotating motor mounted on the bottom of the mounting plate 13, a driving wheel 12 mounted on the output end of the rotating motor, and a driven wheel 8 mounted on the outside of the cleaning box 10 and meshing with the driving wheel 12. The working box 2 An extraction mechanism is installed inside the working box 2 to extract the cleaning liquid inside the water tank 11 into the water cavity 16. The extraction mechanism includes a water pump 7 installed on the inner wall of the working box 2, an annular plate 9 installed on one side of the mounting plate 13, and a notch opened at the bottom of the annular plate 9. The bottom of the annular plate 9 is rotatably connected to the top of the cleaning box 10. The inlet of the water pump 7 is installed with a water inlet pipe extending into the water tank 11, and the outlet of the water pump 7 is connected with the notch through the water outlet pipe. The bottom of the notch is connected with the water cavity 16. A drain port is opened outside the cleaning box 10, and the sprayed cleaning liquid will flow into the water tank 11 again through the drain port, so that it can be recycled.

[0022] It should be noted that when the detection head 17 needs to be cleaned during use, the pneumatic cylinder 3 will drive the connecting plate 4 to move upward, and then the fixing plate 5 will move upward. When the detection head 17 moves to one side of the cleaning sponge 18, the sealing block 14 at the bottom of the detection head 17 will seal the second opening, and then the water pump 7 and the rotating motor will be started. The water pump 7 will draw the cleaning liquid in the water tank 11 into the notch opened at the bottom of the annular plate 9. The water entering the notch will flow into the water cavity 16 and finally be sprayed out through multiple nozzles 15. The rotating motor will drive the driving wheel 12 to rotate. With the cooperation of the driving wheel 12 and the driven wheel 8, the cleaning box 10 will rotate. At this time, the cleaning sponge 18 will surround the detection head 17. Since one side of the cleaning sponge 18 is in contact with the outside of the detection head 17, the detection head 17 can be scrubbed at multiple angles during rotation to prevent the salt scale on the detection head 17 from affecting the detection result.

[0023] Example 2

[0024] like Figure 1 - Figure 5 As shown, a precise Baume meter is provided, wherein the bottoms of the cleaning tank 10, the working tank 2 and the floating tank 1 are provided with corresponding second openings 20, and the bottom of the detection head 17 and the outside of the mounting rod 19 are provided with sealing blocks 14 used in conjunction with the second openings 20.

[0025] It should be noted that, when this kind of Baume meter with precise measurement is in use, when the driving mechanism drives the detection mechanism to move downward and makes the detection head 17 located at the bottom of the floating tank 1, the second opening 20 can be blocked by the sealing block 14 outside the mounting rod 19; when the driving mechanism drives the detection mechanism to move upward and makes the detection head 17 located inside the cleaning tank 10, the sealing block 14 located at the bottom of the detection head 17 will block the second opening 20, thereby preventing brine from backflowing into the cleaning tank 10.

[0026] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
