Two groups of fixed blocks 18 are installed on the outer wall of the guide frame 3, and screw rods 19 are rotatably installed on the two groups of fixed blocks 18. A knob 20 is installed on the bottom side of the screw rod 19, and the screw rod 19 passes through the third lifting block 15; when working, the existing sewage treatment drug delivery device cannot accurately weigh the drugs when delivering the drugs because it does not have a weighing structure, resulting in poor accuracy of the delivery amount, affecting the delivery efficiency. By rotating the knob 20, the screw rod 19 is driven to rotate, and the screw rod 19 drives the third lifting block 15 thereon to move vertically, and the third lifting block 15 drives the second lifting block 12 to move vertically, and the second lifting block 12 drives the second electrode sheet 14 to move vertically, thereby realizing the adjustment of the distance between the second electrode sheet 14 and the first electrode sheet 13, and according to the scale line 16, the distance between the second electrode sheet 14 and the first electrode sheet 13 is accurately adjusted, thereby realizing accurate adjustment of the drug amount;

[0020] Afterwards, the second solenoid valve 31 on the storage box 29 is controlled to open through the control panel 32, and the drug particles fall from the guide tube 30 into the weighing bucket 6.

At this time, the internal circuit of the indicator light 17 is connected, and the indicator light 17 sends an electrical signal to the control panel 32.

[0021] See also Figure 4-5As shown, the fixing plate 2 is mounted with a support rod 21, a support plate 22 is mounted on the support rod 21, a circular groove 23 is provided on the support plate 22, an assembly groove 24 is provided on the inner wall of the circular groove 23, a pulse electromagnet 25 is mounted on the inner wall of the assembly groove 24, the pulse electromagnet 25 is connected to the control panel 32 through an internal circuit, a plurality of second springs 26 are mounted on the inner wall of the assembly groove 24, a connecting plate 27 is mounted on the second spring 26, an iron sheet 28 is mounted on the connecting plate 27, the pulse electromagnet 25 and the iron sheet 28 are annular structures, and the connecting plate 2 7 is provided with a storage box 29, in which medicine particles are placed, a guide tube 30 is provided at the bottom of the storage box 29, and a second solenoid valve 31 is provided on the guide tube 30, and the second solenoid valve 31 and the first solenoid valve 8 are connected to the control panel 32 through an internal circuit; when working, when the existing sewage treatment medicine delivery device delivers medicine, the stored medicine particles are prone to agglomeration, and since the agglomerated medicine particles cannot be dispersed, the storage effect of the medicine particles is poor, which affects the delivery effect, and a sinusoidal current is passed through the control panel 32. The wire is passed into the pulse electromagnet 25, so that the pulse electromagnet 25 is magnetized, and the sinusoidal current switches between positive and negative half cycles. Whenever the positive and negative half cycles of the sinusoidal current are switched, the sinusoidal current disappears. The frequency of the switching between the positive and negative half cycles of the sinusoidal current is very high, so the frequency of the magnetic field generated by the pulse electromagnet 25 is also very high. The magnetic force generated by the pulse electromagnet 25 is also instantaneous. The moment the pulse electromagnet 25 generates magnetic force, it attracts the iron sheet 28 to move toward the pulse electromagnet 25, and the iron sheet 28 drives the connecting plate 27 to move vertically upward, and the connecting plate 27 drives the storage The material box 29 moves vertically upward, and then the magnetic force disappears. Under the pulling force of the second spring 26, the second spring 26 pulls the connecting plate 27 to move vertically downward, and the connecting plate 27 drives the material storage box 29 to move vertically downward. Since the switching frequency of the generation and disappearance of the magnetic field is extremely high, the material storage box 29 generates high-frequency vibrations, and the material storage box 29 drives the drug particles placed inside it to vibrate, so that the locking force between the drug particles is destroyed, and the drug particles are prompted to be redispersed, which is beneficial to improving the dispersion efficiency of the drug particles and the storage effect of the drug particles.

[0022] Working principle: when the existing sewage treatment drug delivery device delivers drugs, it is not possible to accurately weigh the drugs because it does not have a weighing structure, resulting in poor accuracy of the delivery amount, affecting the delivery efficiency. By turning the knob 20, the screw rod 19 is driven to rotate, and the screw rod 19 drives the third lifting block 15 thereon to move vertically, and the third lifting block 15 drives the second lifting block 12 to move vertically, and the second lifting block 12 drives the second electrode sheet 14 to move vertically, thereby realizing the adjustment of the distance between the second electrode sheet 14 and the first electrode sheet 13. According to the scale line 16, the distance between the second electrode sheet 14 and the first electrode sheet 13 is accurately adjusted, thereby realizing the accurate adjustment of the drug amount; then the control panel 32 is used to control the first lifting block 15 on the storage box 29 When the second solenoid valve 31 is opened, the drug particles fall from the guide tube 30 into the weighing hopper 6. The overall weight of the weighing hopper 6 increases, and the weighing hopper 6 moves vertically downward. The weighing hopper 6 presses the first spring 9 downward, and at the same time, the weighing hopper 6 drives the first lifting block 11 to move vertically downward, and the first lifting block 11 drives the first electrode sheet 13 to move vertically downward until the first electrode sheet 13 and the second electrode sheet 14 contact. At this time, the internal circuit of the indicator light 17 is connected, and the indicator light 17 sends an electrical signal to the control panel 32. After receiving the electrical signal, the control panel 32 controls the second solenoid valve 31 on the storage box 29 to close, and at the same time controls the first solenoid valve 8 on the weighing hopper 6 to open, thereby achieving accurate weighing of the drug. The drug falls from the weighing hopper 6 into the sewage treatment tank, achieving In order to deliver the medicine, this structure can accurately weigh the medicine, which is beneficial to improving the accuracy of the delivery amount and the delivery efficiency. When the existing sewage treatment medicine delivery device delivers the medicine, the stored medicine particles are prone to agglomeration. Since the agglomerated medicine particles cannot be dispersed, the storage effect of the medicine particles is poor, which affects the delivery effect. The control panel 32 is used to pass the sinusoidal current through the wire to the pulse electromagnet 25, so that the pulse electromagnet 25 is magnetized, and the sinusoidal current will switch between positive and negative half cycles. Whenever the positive and negative half cycles of the sinusoidal current are switched, the sinusoidal current disappears. The frequency of the positive and negative half cycles of the sinusoidal current is very high, so the frequency of the magnetic field generated by the pulse electromagnet 25 is also very high. The magnetic force generated is also instantaneous. The pulse electromagnet 25 generates magnetic force at the moment it attracts the iron sheet 28 to move toward the pulse electromagnet 25. The iron sheet 28 drives the connecting plate 27 to move vertically upward, and the connecting plate 27 drives the storage box 29 to move vertically upward. Then the magnetic force disappears. Under the pulling force of the second spring 26, the second spring 26 pulls the connecting plate 27 to move vertically downward, and the connecting plate 27 drives the storage box 29 to move vertically downward. Since the switching frequency of the generation and disappearance of the magnetic field is extremely high, the storage box 29 generates high-frequency vibrations, and the storage box 29 drives the drug particles placed inside it to vibrate, so that the locking force between the drug particles is destroyed, prompting the drug particles to be redispersed, which is beneficial to improving the dispersion efficiency of the drug particles and improving the storage effect of the drug particles.
