Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a three-tank automatic PAM medicine-brewing device. Background Technique

[0002] PAM (polyacrylamide) is a flocculant, generally used for raw water treatment, sewage treatment and industrial water treatment in industrial water treatment. PAM plays the role of coagulation, clarification of suspended particles and sludge dewatering in water treatment, and can increase the utilization rate of water reuse cycle. However, PAM dry powder is difficult to dissolve, and it is difficult to dissolve manually, which is easy to cause lumps. And because the addition amount of dry powder medicine in the PAM solution is small, the requirement for the dosing amount is more precise, and the medicament solution prepared manually is difficult to control accurately.

[0003] For example, the patent application with the publication number of CN111229066A in the prior art discloses a single-cylinder six-tank full-automatic medicine-brewing machine. The first and second tanks of this patent application are for stirring, the third, fourth and fifth tanks are for aging, and the sixth tank is for temporary storage. It is easy to cause lumps during aging and temporary storage, and all tanks are in one cylinder, with a small medicine-brewing capacity and a waste of time. Therefore, a three-tank automatic PAM medicine-brewing device is needed to solve the above technical problems. Content of the Utility Model

The inside of the medicine box 1 is respectively provided with a water inlet pipeline 2 and a drain pipeline 4. One end of the water inlet pipeline 2 and the drain pipeline 4 is communicated with the medicine box 1, and the other end is communicated with the outside. The controller 5 is electrically connected to the medicine box 1, the water inlet pipeline 2 and the dry powder feeding mechanism 3 respectively. The medicine box 1 is welded by stainless steel plates, with strong corrosion resistance and long service life of the equipment. Stirrers are provided in all three tanks, which can ensure uniform preparation of the liquid medicine.

[0027] Preferably, a partition 14 is further provided inside the medicine box 1. The medicine box 1 is sequentially divided into a dissolution tank 11, a ripening tank 12, and a storage tank 13 from left to right by the partition 14. Stirrers are respectively provided in the dissolution tank 11, the ripening tank 12, and the storage tank 13. An overflow port is opened above the partition 14. A liquid level gauge is provided in the storage tank 13, and the liquid level gauge is in signal connection with the controller 5. First, the liquid medicine is prepared in the dissolution tank 11 according to the concentration requirement to determine the relationship between the water inflow and the dry powder medicine dosage. Then, water is fed and dry powder medicine is added in the same proportion. When the liquid level of the liquid medicine in the dissolution tank 11 reaches the overflow port, it flows to the ripening tank 12 through the overflow port. In the ripening tank 12, the liquid medicine is further stirred. When the liquid level of the liquid medicine in the ripening tank 12 reaches the overflow port, it flows to the storage tank 13 through the overflow port.

[0028] Preferably, the water inlet pipeline 2 is sequentially provided with a pressure gauge 21, a three-way valve 22, a solenoid valve 23, and a flow meter 24. One end of the water inlet pipeline 2 close to the pressure gauge 21 is communicated with the outside, and the other end is communicated with the dissolution tank 11. A pipeline is connected in parallel on the water inlet pipeline 2 between the pressure gauge 21 and the flow meter 24. When water needs to be inlet, all the manual ball valves 22 on the water inlet pipeline 2 are opened, the solenoid valve 23 is opened through the PLC in the controller 5, and the opening time of the solenoid valve 23 is set according to the water inlet flow rate displayed by the flow meter 24. When the total water inlet volume reaches the requirement, the solenoid valve 23 is closed and the water inlet stops.

[0029] Preferably, the drain pipeline 4 includes a drain main pipe, a drain branch pipe 41, and an overflow pipeline 42. The bottom sides of the dissolution tank 11, the ripening tank 12, and the storage tank 13 are all connected to the drain main pipe through the drain branch pipe 41. An overflow pipeline 42 is further connected to the drain main pipe. The overflow pipeline 42 penetrates through the outer wall of the dissolution tank 11 and extends to the upper part inside. The manual ball valves 22 on the drain branch pipe 41 are all in a normally closed state, and the manual ball valve 22 on the drain main pipe is in a normally open state. When too much water is inlet in the dissolution tank 11, the excess liquid medicine can be discharged through the overflow pipe to prevent the liquid medicine from overflowing from the feeding port.

[0030] Preferably, the dry powder feeding mechanism 3 includes a storage hopper, a variable-frequency screw conveyor, a vibrator, and a level switch. The variable-frequency screw conveyor is connected to the bottom of the storage hopper. The vibrator and the level switch are installed on the side plate of the storage hopper. The level switch is used to transmit a signal to the controller 5 and output a signal to the variable-frequency screw conveyor and the vibrator. The variable-frequency screw conveyor can control the proportioning amount of the dry powder medicine by controlling the motor frequency. The vibrator is installed on the side wall of the storage hopper and can vibrate the dry powder medicine attached to the side wall into the storage hopper. The level switch is used to detect the amount of dry powder medicine in the storage hopper. When the amount of dry powder medicine is lower than the position of the level switch, a signal is transmitted to the PLC, and then the PLC issues a signal to stop the operation of the variable-frequency screw conveyor.

[0031] Preferably, an auxiliary heating coil is wrapped around the variable-frequency screw conveyor rod to keep the variable-frequency screw conveyor rod dry and prevent the dry powder agent in the rod from being affected by moisture and caking.

[0032] Preferably, the controller 5 includes a PLC, a knob switch and an indicator light. A control program is written in the PLC. By receiving the signals of each sensor, it outputs control signals. The PLC receives the working states of the mixer, the variable-frequency screw conveyor rod, the solenoid valve 23 and the vibrator. The knob switch controls the motors of the three mixers, the dry powder feeding mechanism 3, the vibrator and the solenoid valve 23, and sets three working modes, corresponding to "manual on", "stop" and "automatic" respectively. In the "automatic" mode, the programs written in the PLC automatically control each electric actuator and are displayed through the indicator light.

[0033] Preferably, both the water inlet pipeline 2 and the drain pipeline 4 adopt UPVC pipe fittings.
