Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coagulant preparation, and more specifically, it relates to a preparation device for an efficient coagulant. Background Technique
[0002] Coagulant preparation: Coagulants are commonly used agents in the water treatment process, which can promote the coagulation of suspended solids and colloidal particles in water into larger flocs, thus facilitating their separation from water. Coagulants can be divided into two categories: inorganic salts and polymers. Common inorganic salt coagulants include aluminum sulfate, polyaluminum chloride, ferric trichloride, etc., while polymers include polyacrylamide, etc.
[0003] Currently, the coagulant preparation devices on the market include coagulant dosing devices. Such devices can mix solid raw materials and liquid raw materials, enabling the outflow of the finished coagulant to provide a coagulation effect for subsequent sewage treatment. However, after long-term transportation and storage of solid coagulant raw materials, the internal powder will agglomerate and crystallize, resulting in a poor solution mixing effect, requiring longer stirring and mixing time, and reducing production efficiency.
[0004] Therefore, a preparation device for an efficient coagulant is proposed. This device crushes solid raw materials through a crusher to prevent raw material agglomeration and crystallization, initially mixes solid raw materials and liquid raw materials to form a solution through primary stirring, and prevents agglomerated and crystallized raw materials from flowing out through a filter screen to avoid waste of raw materials; subsequently, liquid raw materials are added to the preliminarily mixed solution for secondary stirring to fully mix the solution. The two stirrings improve the utilization efficiency of raw materials, reduce production costs. On the other hand, when the solution in the secondary stirring tank is full, the primary stirring tank can still prepare the solution, improving production efficiency. Summary of the Utility Model
[0005] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a preparation device for an efficient coagulant that reduces waste of raw materials, improves the utilization efficiency of raw materials, reduces production costs, and improves production efficiency.

The conveyor belt is far from the crusher and is provided with a frame. One side of the frame close to the conveyor belt is provided with a primary stirring assembly, and the bottom end of the primary stirring assembly is provided with a secondary stirring assembly.
[0008] By adopting the above technical solution, powdery raw materials are added to the crusher to break up the agglomeration or crystallization generated during transportation or storage and restore them to powder form, reducing the stirring and synthesis time in the subsequent preparation process and improving production efficiency.
[0009] The present utility model is further configured as follows: The primary stirring assembly includes a primary stirring tank, which is configured as a hollow tank-like structure. A solid feeding port is provided at the top end of the primary stirring tank, and the shape of the solid feeding port is adapted to the outlet of the conveyor belt.

The primary stirring rod is configured as a worm structure with fan blades. A primary stirring motor is provided at the top end of the primary stirring rod, and the primary stirring motor is provided at the center of the top end of the primary stirring tank.
[0011] By adopting the above technical solution, a concentrated solution is obtained through primary stirring, which accelerates the preparation time of the coagulant. On the other hand, when the secondary stirring assembly is filled with the finished coagulant solution, the concentrated solution can be prepared and stored in advance in the primary stirring assembly, improving the preparation efficiency of the coagulant and saving production time.
[0012] The present utility model is further configured as follows: A filter screen is provided at the bottom of the primary stirring tank. The filter screen is configured as a circular structure with multiple holes. A semi-finished product discharge port is connected to the bottom end of the filter screen. The semi-finished product discharge port is configured as a hollow cylindrical structure and is connected to communicate the primary stirring assembly and the secondary stirring assembly.
[0013] By adopting the above technical solution, primary stirring and filtration reduce the crystallization of the powder raw materials in the coagulant, reduce the raw material input, improve the utilization efficiency of the raw materials, and reduce the production cost.
[0014] The present utility model is further configured as follows: The secondary stirring assembly includes a secondary stirring tank, which is configured as a hollow tank-like structure. A circular liquid supplementing port is provided at the top of the secondary stirring tank. A finished product outlet is provided at a position of the secondary stirring tank away from the primary stirring assembly.

A secondary stirring rod is provided at the bottom end of the secondary stirring motor. The secondary stirring rod is configured as a worm structure with fan blades.
[0016] By adopting the above technical solution, through secondary stirring, the undissolved powder remaining in the concentrated solution is further dissolved, further improving the utilization efficiency of the raw materials and reducing the production cost.
[0017] In summary, the present application includes at least one of the following beneficial technical effects:
[0018] 1. After the powdered raw materials are transported or stored, they are crushed by a crusher to reduce the agglomeration and crystallization of the powdered raw materials. The conveyor belt transports the raw materials to the outlet and into the solid feeding port that matches their shape. The powdered raw materials enter the inside of the primary stirring tank. At the same time, the pipeline at the liquid feeding port inputs the liquid raw materials into the inside of the primary stirring tank. After the feeding is completed, the primary stirring motor starts to drive the primary stirring rod to rotate, so that the two raw materials are fully mixed to produce a concentrated solution. By obtaining the concentrated solution through primary stirring, the preparation time of the coagulant is accelerated. On the other hand, when the finished coagulant solution fills the secondary stirring component, the concentrated solution can be prepared and stored in advance in the primary stirring component, improving the preparation efficiency of the coagulant and saving production time.
[0019] 2. After the primary preparation is completed, the concentrated solution is filtered through a filter screen to remove the residual powdered raw materials. The concentrated solution inside the primary stirring tank is discharged through the semi-finished product outlet into the secondary stirring component. After being stirred and filtered once by the primary stirring component, the crystallization of the powdered raw materials in the coagulant is reduced, the raw material input is reduced, the raw material utilization efficiency is improved, and the production cost is reduced.
[0020] 3. The concentrated solution flowing in through the semi-finished product outlet enters the secondary stirring tank. At the same time, the pipeline inside the liquid supplement port inputs the liquid raw materials into the inside of the primary stirring tank. After the secondary stirring motor starts to drive the secondary stirring rod to rotate, the concentrated solution is fully diluted to produce the finished coagulant solution, and the finished coagulant solution flows out through the finished product outlet. Through secondary stirring, the undissolved powder residues in the concentrated solution are further dissolved, further improving the raw material utilization efficiency and reducing the production cost.
