Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a rapid separation charge-type chromium concentration measuring device for leather making, comprising a base 1, a first filter cup 2, a main mixing cup 3, a secondary mixing cup 4, a second filter cup 5, a measuring instrument 6, a filter cylinder 7, a filter screen 8, a support 9, a stirring rod 10, a square rod 11, a positioning rod 12, a rotating cap 13, a driving mechanism 14, a base plate 1401, a motor 1402, and a square sleeve 1403. The first filter cup 2, the main mixing cup 3, the secondary mixing cup 4, and the second filter cup 5 are sequentially installed on the inner wall of the base 1 from left to right, and the base 1 is positioned on the side of the second filter cup 5. A measuring instrument 6 is provided on the upper surface, and filter cylinders 7 are installed on the inner walls of the first filter cup 2 and the second filter cup 5. A filter screen 8 is fixedly connected to the lower inner wall of the filter cylinder 7. A bracket 9 is fixed on the upper outer wall of the main mixing cup 3 and the auxiliary mixing cup 4. A stirring rod 10 is movably installed on the inner wall of the middle part of the bracket 9. A square rod 11 is fixedly provided on the upper end of the stirring rod 10. Positioning rods 12 are fixed on both sides of the upper surface of the bracket 9. A rotating cap 13 is sleeved on the upper outer wall of the positioning rod 12. A drive mechanism 14 is installed on the outer wall of the positioning rod 12 below the rotating cap 13.

[0025] The first filter cup 2, the main mixing cup 3, the secondary mixing cup 4, and the second filter cup 5 are all slidably connected to the base 1, making it easy for the user to move the first filter cup 2, the main mixing cup 3, the secondary mixing cup 4, and the second filter cup 5 on the base 1 respectively.

[0026] Both the first filter cup 2 and the second filter cup 5 form a sliding structure with the filter cartridge 7, which makes it easy for the user to move the filter cartridge 7 to install or remove the filter screen 8.

[0027] The support 9 and the stirring rod 10 form a rotating structure, which facilitates the drive mechanism 14 to drive the stirring rod 10 to rotate relative to the support 9, thereby reducing the workload of the user by mixing the materials with the stirring rod 10.

[0028] The drive mechanism 14 includes a base plate 1401, a motor 1402, and a square sleeve 1403. The base plate 1401 is sleeved on the outer wall of the positioning rod 12, and the motor 1402 is installed in the middle of the upper surface of the base plate 1401. The lower end of the output shaft of the motor 1402 is fixedly connected to the square sleeve 1403, so that the stirring rod 10 can be driven by the drive mechanism 14, so that the device can automatically mix materials, thereby increasing the ease of use of the device.

[0029] The substrate 1401 and the positioning rod 12 are slidably arranged so that the substrate 1401 can slide relative to the positioning rod 12 when the user moves and disassembles the drive mechanism 14.

[0030] The substrate 1401 and the rotating cap 13 are attached to each other, and the rotating cap 13 is threadedly connected to the positioning rod 12, which makes it easy for the user to rotate the rotating cap 13 to disengage from the positioning rod 12, thereby facilitating the user to move and disassemble the drive mechanism 14.

[0031] The square sleeve 1403 and the square rod 11 are slidably connected, so that when the user moves and disassembles the drive mechanism 14, the square sleeve 1403 slides relative to the square rod 11.

[0032] Working principle: When using this rapid separation charge-type chromium concentration measuring device for leather tanning, firstly as follows... Figure 1-5As shown, the user moves the base plate 1401 onto the positioning rod 12 on the main mixing cup 3. As the base plate 1401 moves, it drives the square sleeve 1403 to be fitted onto the square rod 11. Then, the user fits the screw cap 13 onto the positioning rod 12 and tightens it. At this time, the screw cap 13 is in close contact with the base plate 1401, thereby stably fixing the drive mechanism 14 onto the main mixing cup 3. Subsequently, the user pours the tanning wastewater and anion exchange precipitant into the main mixing cup 3. Then, the user starts the motor 1402. Next, the motor 1402 drives the square sleeve 1403 to rotate, and then the square sleeve 1403 drives the square rod. Rotate the square rod 11, then drive the stirring rod 10 in the main mixing cup 3 to rotate relative to the support 9, thereby allowing the wastewater and precipitant to mix automatically in the main mixing cup 3. After the materials are mixed, the user turns off the motor 1402. At this time, the materials in the main mixing cup 3 are allowed to settle. After the settling is complete, the user moves the main mixing cup 3 away from the base 1. Next, the user pours the materials in the main mixing cup 3 into the first filter cup 2 and then puts the main mixing cup 3 back in its original position. At this time, the filter screen 8 on the first filter cup 2 filters the materials. Subsequently, the anionic chromium complex accumulates in the filter screen 8 on the first filter cup 2. Then the user... Anionic chromium complex is placed in measuring instrument 6 for concentration detection. Then, the user moves the filter cartridge 7 on the first filter cup 2 to detach it from the first filter cup 2. Next, the user pours the liquid in the first filter cup 2 into the secondary mixing cup 4. Then, the user rotates the cap 13 to detach it from the positioning rod 12. Subsequently, the user moves the substrate 1401 to detach it from the positioning rod 12 on the main mixing cup 3. Then, the user fixes the drive mechanism 14 on the secondary mixing cup 4 as described above. Next, the user pours the cationic precipitant into the secondary mixing cup 4. Then, the user starts the motor 1402 to make the stirring rod 10 in the secondary mixing cup 4 mix the waste liquid and the cationic precipitant. The device is designed to automatically mix tanning wastewater and precipitant, thus improving its ease of use. After the materials are mixed, the user turns off the motor 1402 and allows the materials to settle in the secondary mixing cup 4. After settling, the user moves the secondary mixing cup 4 to pour the materials into the second filter cup 5. At this time, the filter screen 8 on the second filter cup 5 filters the materials. Then, the cationic chromium complex accumulates in the filter screen 8 on the second filter cup 5. Next, the user puts the cationic chromium complex into the measuring instrument 6 for concentration detection, thereby performing charge separation and concentration detection of chromium-containing tanning wastewater.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
