By installing a diversion pipe and an extrusion duct on the dry powder storage tank, the extrusion fan blows the dry powder into the maturation and mixing component in a powder mist state, where it is fully mixed with the process water to avoid clumping. The prepared flocculant mother liquor is pumped into the mother liquor collection and storage tank by a water pump, and a certain amount of process water is added to the dilution tank to dilute it, thus completing the preparation of the flocculant.
This method achieves uniform mixing of dry powder and process water, avoids clumping, ensures efficient preparation of flocculants, and improves the quality and production efficiency of flocculants.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of flocculant production technology, and in particular relates to a flocculant production device for wastewater. Background Technology
[0002] The core role of flocculants in bauxite red mud slurry treatment is to aggregate fine suspended particles into large and dense flocs through physicochemical action, thereby significantly accelerating the settling speed and improving the solid-liquid separation effect. In the preparation process of flocculants, APAM dry powder needs to be dispersed in a certain amount of process water first, so that the APAM dry powder dissolves in the process water and is stirred and matured to form flocculant mother liquor. Subsequently, according to the needs of flocculation, the mother liquor is diluted with process water to form a certain proportion of flocculant. When preparing matured flocculant mother liquor, uneven distribution of APAM dry powder can easily cause a high-concentration viscous gel layer to form instantly on the outer layer of dry powder particles, which will coat the inner unwetted dry powder, prevent water from continuing to penetrate, and form insoluble hard lumps.
[0003] To address these issues, we provide a wastewater flocculant production apparatus. Utility Model Content
[0004] The purpose of this invention is to provide a flocculant production device for wastewater. A guide pipe is connected to a converging cover at the upper end of the dry powder storage tank of the powder-spreading assembly. The end of the guide pipe away from the converging cover extends downwards into the curing and mixing assembly. A set of agitator ducts is circumferentially connected to the side wall of the dry powder storage tank. An agitator fan is connected inside the agitator ducts, blowing external airflow into the dry powder storage tank. This causes the dry powder in the tank to be blown up and enter the guide pipe, ultimately allowing the dry powder to be blown downwards from the powder-spreading pipe, thus being blown into the curing and mixing assembly in a powder mist state. In the curing and mixing assembly, the dry powder is thoroughly mixed with the process water in the curing and mixing assembly to prevent clumping. A water pump is connected to the outlet of the curing and mixing assembly, and the outlet of the water pump is connected to the inlet of the mother liquor collection and storage tank. The outlet of the mother liquor collection and storage tank is connected to the dilution tank through a pipeline. The water pump pumps the prepared flocculant mother liquor into the mother liquor collection and storage tank. When flocculant needs to be prepared, the flocculant in the mother liquor collection and storage tank is collected into the dilution tank, and a certain amount of process water is added to the dilution tank to dilute the flocculant mother liquor, thereby completing the preparation of the required flocculant.

Example 1
[0025] Please see Figure 1 and Figure 2 This utility model relates to a flocculant production device for wastewater, comprising a powder spreading component 1, a maturation and mixing component 2, a mother liquor collection and storage tank 3, and a dilution tank 4. The powder spreading component 1 includes a dry powder storage tank 101, a diversion pipe 102, and a set of extrusion air ducts 103. A diversion pipe 102 is connected to a converging cover 101a at the upper end of the dry powder storage tank 101 of the powder spreading component 1. The powder spreading pipe 102a, which extends downward and is fixed at the end of the diversion pipe 102 away from the converging cover 101a, extends into the maturation and mixing component 2. A set of extrusion air ducts 103 are circumferentially connected to the side wall of the dry powder storage tank 101. An extrusion fan 103a is sleeved inside the extrusion air ducts 103, and the extrusion fan 103a blows external airflow into the dry powder storage tank 101, causing the dry powder storage tank 101 to... The dry powder is blown up and enters the drainage pipe 102, and finally blown downward from the powder spraying pipe 102a, so that the dry powder is blown into the maturation mixing component 2 in the form of powder mist, so that the dry powder is fully mixed with the process water of the maturation mixing component 2 and avoids agglomeration. By connecting the water pump to the outlet end of the maturation mixing component 2 and connecting the outlet end of the water pump to the inlet end of the mother liquor receiving and storage tank 3, and connecting the outlet end of the mother liquor receiving and storage tank 3 to the dilution tank 4 through the pipeline, the water pump pumps the prepared flocculant mother liquor into the mother liquor receiving and storage tank 3. When flocculant needs to be prepared, the flocculant in the mother liquor receiving and storage tank 3 is collected into the dilution tank 4, and a certain amount of process water is added to the dilution tank 4 to dilute the flocculant mother liquor, thereby completing the preparation of the required flocculant.
[0026] Specifically, a gathering cover 101a is fixedly covered on the upper end of the dry powder storage tank 101. The upper end of the gathering cover 101a is connected to one side of the diversion pipe 102. A set of circumferential air ducts 103 are fixedly sleeved on the side wall of the dry powder storage tank 101. The end of the duct 103 extending into the dry powder storage tank 101 extends downward. An air fan 103a is provided inside the outer end of the duct 103. The end of the diversion pipe 102 away from the gathering cover 101a is bent downward and fixedly provided with a powder spreading pipe 102a.

A drainage fan 102b-1 is installed inside the drainage machine cover 102b. The drainage fan 102b draws external air into the drainage tube 102, causing the powder mist dry powder entering the drainage tube 102 to be blown toward one end of the powder spreading tube 102a.
[0028] Furthermore, a funnel-shaped powder outlet cover 102c is fixedly installed at the lower end of the powder spraying pipe 102a.

The suction fan 101a-1 draws the dry powder blown up in the dry powder storage tank 101 into the diversion pipe 102. The diversion fan 102b draws external air into the diversion pipe 102, causing the powder mist dry powder entering the diversion pipe 102 to be blown toward one end of the powder spreading pipe 102a.

The mixed solution flows along the threaded water trough 202 towards the bottom of the outer sleeve 203, thereby mixing the dry powder and process water during the flow process and forming a flocculant mother liquor.
[0034] Specifically, the threaded water tank 202 is located at the lower end of the mixing disc 201 and is connected to the mixing disc 201. The outer sleeve 203 is sleeved on the lower outer side of the threaded water tank 202 and the mixing disc 201. The lower outlet end of the outer sleeve 203 is connected to a water pump through a pipe. The outlet end of the water pump connected to the outer sleeve 203 is connected to the mother liquor receiving and storage tank 3 through a pipe. The powder discharge cover 102c extends into the upper part of the mixing disc 201.
[0035] Furthermore, the upper end of the dilution tank 4 is covered with a tank cover 401, and a stirring motor 402 is installed at the upper end of the tank cover 401. The output end of the stirring motor 402 passes through the tank cover 401, and a stirring paddle 402a is fixedly connected to the output end of the stirring motor 402. The stirring paddle 402a extends into the interior of the dilution tank 4, and a process water inlet pipe 403 is connected to the upper end of the tank cover 401.
[0036] The operation process in this embodiment is as follows:
[0037] The powder mist emitted by the powder-spraying component 1 is evenly mixed into the mixing pan 201 with the process water, and the mixed solution flows along the threaded water groove 202 to the bottom of the outer sleeve 203, so that the dry powder and process water are mixed during the flow and form flocculant mother liquor; the flocculant mother liquor is pumped into the mother liquor collection tank 3; when flocculant needs to be prepared, the flocculant in the mother liquor collection tank 3 is collected into the dilution tank 4, and a certain amount of process water is added to the dilution tank 4 to dilute the flocculant mother liquor. The stirring motor 402 drives the stirring paddle 402a to rotate, so that the flocculant mother liquor and the process water added to the dilution tank 4 are fully mixed, thereby completing the preparation of the required flocculant.
