Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a wastewater treatment dosing simulation device. Background Art

[0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. There are many types of industrial wastewater with complex components. For example, electrolytic salt industrial wastewater contains mercury, heavy metal smelting industrial wastewater contains lead, cadmium and other metals, electroplating industrial wastewater contains cyanide and chromium and other heavy metals, petroleum refining industrial wastewater contains phenol, pesticide manufacturing industrial wastewater contains various pesticides, etc. Since industrial wastewater often contains a variety of toxic substances, polluting the environment is very harmful to human health, so in the process of treating industrial wastewater, it is necessary to use industrial wastewater stations for purification.

[0003] At present, industrial wastewater stations need to use dry powder dosing devices when treating wastewater. The powder for purifying water sources is dissolved in water and then put into the wastewater pool for purification. However, during the use of the dry powder dosing devices currently used, the cost of automatic dosing is high, the efficiency of manual dosing is low, and the dosage of the drug cannot be controlled, resulting in excessive or insufficient dosage of the drug, affecting the treatment effect.

[0004] Therefore, there is an urgent need to provide a wastewater treatment dosing simulation device to solve the above problems. Summary of the invention

[0010] Through the above technical solution, the first filter plate and the second filter plate filter the wastewater entering the filter box, and the inclined plate guides the filtered wastewater to the through hole position, so that the wastewater enters the mixing box for mixing.

[0011] The present invention is further configured as follows: a guide rod is fixedly installed inside the mixing box, a water outlet is provided on one side of the mixing box, and a water inlet is provided on the upper surface of the mixing box.

[0012] Through the above technical solution, the setting of the guide rod facilitates the cleaning plate to move up and down inside the mixing box, the water outlet is used to discharge the purified wastewater, and the setting of the delivery port is used to transport the dry powder into the mixing box.

[0013] The present invention is further configured as follows: the medicine adding mechanism includes a medicine storage box, a lifting bracket is slidably connected to the inside of the medicine storage box, a rotating plate is rotatably connected to the inside of the medicine storage box, the rotating plate is in contact with one end surface of the lifting bracket, a medicine inlet is provided on one side of the medicine storage box, a fence is fixedly installed on one side of the medicine storage box, the delivery port is provided inside the fence, a scale is fixedly installed on the surface of the medicine storage box, and an extension plate is fixedly installed on one side of the medicine storage box.

The medicine inlet is used to replenish the dry powder inside the medicine storage box. The fence is set to protect the delivery port to prevent the dry powder from scattering and causing waste when it is delivered, and at the same time prevent external dust from entering the mixing box from the delivery port.

When the transmission rod rotates, the lower protrusion follows the rotation until it contacts the upper protrusion. The lower protrusion squeezes the upper protrusion so that the lifting bracket can be lifted and lowered inside the medicine storage box. When the lifting bracket rises, it drives the lifting baffle to rise inside the baffle groove, so that the medicine outlet is opened. At the same time, one end of the lifting bracket lifts one end of the rotating plate to tilt the rotating plate, and the dry powder inside the medicine storage box is discharged from the medicine outlet to the delivery port, thereby entering the mixing box to purify the wastewater.

At this time, the control box controls the motor to start, thereby mixing the wastewater and dry powder inside the mixing box. At the same time, the dosing mechanism can add dry powder to the inside of the mixing box, and the cleaning mechanism can further clean the inside of the mixing box.

[0023] The beneficial effects of the present invention are as follows:

The liquid level sensor 6 monitors the wastewater level inside the mixing box 2. When the wastewater level is detected to be appropriate, a signal is sent to the inside of the control box 7. At this time, the control box 7 controls the motor 41 to start. When the motor 41 starts, the transmission rod 42 rotates, so that the stirring piece 43 can stir the wastewater inside the mixing box 2. When the transmission rod 42 rotates, the lower protrusion 44 rotates with it until it contacts the upper protrusion 321. The lower protrusion 44 squeezes the upper protrusion 321 so that the lifting bracket 32 ​​can be inside the medicine storage box 31 The lifting bracket 32 ​​is lifted and lowered. When the lifting bracket 32 ​​rises, it drives the lifting baffle 322 to rise inside the baffle groove 312, so that the medicine outlet 311 is opened. At the same time, one end of the lifting bracket 32 ​​lifts one end of the rotating plate 33, so that the rotating plate 33 is tilted, and the dry powder inside the medicine storage box 31 is discharged from the medicine outlet 311 to the delivery port 23, so that it enters the mixing box 2 to purify the wastewater.
