Description

Technical Field

[0001] The utility model relates to an alkali adding device, in particular to a liquid ammonium sulfate automatic alkali adding device for adjusting pH value, belonging to the technical field of chemical test equipment. Background Art

[0002] Ammonium sulfate is an inorganic substance with the chemical formula (NH4)2SO4, colorless crystals or white particles, and no odor. It decomposes above 280°C. Solubility in water: 70.6g at 0°C, 103.8g at 100°C. It is insoluble in ethanol and acetone. The pH of 0.1mol / L aqueous solution is 5.5. The relative density is 1.77. The refractive index is 1.521. Ammonium sulfate is mainly used as a fertilizer and is suitable for various soils and crops. It can also be used in textiles, leather, medicine, etc.

[0003] Ammonium sulfate is an excellent nitrogen fertilizer (commonly known as fertilizer powder), suitable for general soil and crops. It can make branches and leaves grow vigorously, improve fruit quality and yield, and enhance the resistance of crops to disasters. It can be used as base fertilizer, topdressing and seed fertilizer. It can react with salt to produce ammonium chloride, react with aluminum sulfate to produce ammonium alum, and make refractory materials with boric acid. Adding it to the electroplating solution can increase conductivity. It is also a catalyst for food color, a nitrogen source for culturing yeast in fresh yeast production, an auxiliary dye for acid dyeing, and a leather deashing agent. In the existing liquid ammonium sulfate test, alkali is added to it, generally for pH adjustment experiments. However, most of the existing alkali addition work uses manual automatic alkali addition. After manual alkali addition, the mixed liquid needs to be fully mixed, which increases the intensity of manual testing and is not convenient for use. Utility Model Content

With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0022] According to an embodiment of the utility model, a device for automatically adding alkali to adjust the pH value of liquid ammonium sulfate is provided.

[0023] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4As shown, a liquid ammonium sulfate automatic alkali addition pH adjustment device according to an embodiment of the utility model comprises a lower bottom plate 1, a base 2 is fixedly installed at the center position of the upper surface of the lower bottom plate 1, one side of the upper surface of the base 2 is fixedly connected to the longitudinal vertical plate 3, a transverse plate 4 is fixedly installed at the top of the longitudinal vertical plate 3, the base 2, the longitudinal vertical plate 3 and the transverse plate 4 adopt an integrated structural design, the two ends of the longitudinal vertical plate 3 are respectively arranged perpendicular to the base 2 and the transverse plate 4, a mixing motor 16 is fixedly installed inside the base 2, a rotating disk 12 is fixedly installed on the output shaft of the mixing motor 16, an upper mounting seat is installed outside the mixing motor 16, a straight vibrator 14 is fixedly installed at the center position of the upper surface of the rotating disk 12, and a container fixing seat 13 is fixedly installed on the upper surface of the straight vibrator 14.

[0024] In one embodiment, a container fixing groove is provided inside the container fixing seat 13 , and the container fixing groove is a circular groove, and a plurality of inner silicone columns 15 are installed on the inner wall of the container fixing groove.

[0025] In one embodiment, the plurality of inner silicone columns 15 are distributed at equal intervals around the center point of the container fixing seat 13 .

[0026] In one embodiment, a plurality of hanging columns 5 are fixedly mounted on the lower surface of the horizontal plate 4 . The plurality of hanging columns 5 are circumferentially distributed at equal intervals. A liquid adding cylinder 6 is fixedly mounted between the bottom ends of the plurality of hanging columns 5 .

[0027] In one embodiment, a conical head 7 is fixedly connected to the outer wall of the bottom end of the liquid adding cylinder 6 , and the liquid adding cylinder 6 and the conical head 7 are integrally formed. An inner sealing ring 10 is slidably installed inside the liquid adding cylinder 6 .

[0028] In one embodiment, a drive cylinder 8 is fixedly installed on the upper surface of the cross plate 4 by fixing bolts. The drive cylinder 8 is a pneumatic cylinder or a hydraulic cylinder. The output end of the drive cylinder is movably connected to a drive rod 9, and the bottom end of the drive rod 9 is fixedly connected to the upper surface of the inner sealing ring 10.

[0029] Working principle: When it is necessary to conduct an automatic alkali addition test for adjusting the pH value of liquid ammonium sulfate, the liquid ammonium sulfate can be poured into a container that is adapted to the diameter of the container fixing seat 13 of the utility model, and the container filled with liquid ammonium sulfate is placed in the container fixing groove of the container fixing seat 13. An inner silica gel column 15 is installed inside the container fixing groove, and the container can be tightened on the side by the plurality of inner silica gel columns 15, so that the container can be stably fixed in the container fixing seat 13;

[0030] At the same time, an alkaline solution is injected into the liquid adding cylinder 6. When alkali addition is required, the driving cylinder 8 is set to work, and the driving cylinder 8 drives the driving rod 9 to extend one end distance. At this time, the driving rod 9 drives the inner sealing ring 10 at the bottom to drop a distance of several millimeters.

When the mixing motor 16 is working, the rotating disk 12 drives the container in the container fixing seat 13 to rotate slowly, and the straight vibrator 14 can synchronously drive the container in the container fixing seat 13 to vibrate while rotating, so that the repeated rotation and oscillation mixing of the acidic liquid and the alkaline liquid is completed through the rotation of the motor and the vibration of the straight vibrator 14.

[0032] When the utility model is actually used, the automatic addition of alkaline liquid can be completed extremely conveniently. At the same time, the addition amount of the alkaline liquid can be controlled by the extension distance of the driving rod 9. It is easy to use and has high precision. After the alkaline liquid is added, the rotation of the motor and the vibration of the straight vibrator 14 are used to complete the sufficient rotation and oscillation mixing of the acidic liquid and the alkaline liquid. It has a certain automatic filling and mixing effect, does not require manual operation, and the mixing effect is more uniform, freeing the hands of the test personnel, improving the test efficiency, and having a good use effect.

[0033] In summary, with the aid of the above-mentioned technical scheme of the utility model, the technical problem in the background technology that "most of the existing alkali adding work adopts manual automatic alkali adding treatment, and after manual alkali adding, the mixed liquid needs to be fully mixed, which increases the intensity of manual testing and is inconvenient to use" is solved.
