Technical Field

[0001] This utility model relates to the technical field of dewatering devices, and in particular to a high-efficiency dewatering device for secondary pressure rolling and filtration of turbid circulating water in steelmaking. Background Technology

[0002] A large amount of turbid circulating water is typically generated during steelmaking. To meet discharge standards, this circulating water usually needs to be filtered. Secondary pressure filtration of steelmaking turbid circulating water is a process for further treatment of this water. It is mainly used to further remove suspended solids, impurities, and some oils and other pollutants from the water, thereby improving water quality and enabling water recycling or discharge that meets standards.

[0003] However, some existing secondary pressing and filtration dewatering devices (such as plate and frame filter presses) require periodic shutdowns for unloading during operation, which is time-consuming and results in low dewatering efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a high-efficiency dewatering device for secondary pressure rolling and filtration of turbid circulating water in steelmaking, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

A rotating support frame for driving is fixedly installed inside the dewatering support frame. One end of the rotating support frame is provided with an inlet connector for introducing the turbid circulating water to be treated in steelmaking. One end of the inlet connector is connected to a water delivery tank for water supply. An electromagnetic water guide valve for water supply control is installed inside the water delivery tank. The electromagnetic water guide valve is signal-connected to a dewatering control module for automated control. The dewatering control module is signal-connected to a hydraulic system for driving. One end of the hydraulic system is provided with two sets of plate and frame filter press assemblies for secondary pressing and filtration. A drainage trough for drainage is provided on one side of each plate and frame filter press assembly. Drainage sealing strips for sealing are fixedly installed at both ends of the drainage trough.

[0007] The above technical solution employs the following: the rotating slots at both ends of the dewatering support provide stable support and a foundation for rotation, enabling the rotating support to rotate smoothly inside the dewatering support. The water delivery tank is located inside the dewatering support, which not only saves space but also effectively prevents leakage during water delivery. The water delivery connection slot at one end precisely accommodates the water inlet connector, ensuring that the water inlet connector is installed securely, allowing the turbid circulating water from steelmaking to be treated to flow smoothly into the water delivery tank, thus facilitating subsequent treatment processes.

This enables the precise rotation of the tilting fixed frame, which facilitates the adjustment of the position of the plate and frame filter press assembly. This ensures that one set performs dewatering operation while the other set performs unloading operation, thereby improving dewatering efficiency. The water inlet at one end of the tilting fixed frame provides a channel for the steelmaking turbid circulating water to be treated to enter the plate and frame filter press assembly.

Under the drive of the hydraulic system, the steelmaking turbid circulating water is subjected to secondary pressure, filtration and dewatering treatment. The drainage trough and drainage sealing strip are both set inside the tilting and fixing frame. The drainage sealing strip ensures the sealing of the drainage trough and prevents water leakage after dewatering.

[0041] The working principle of this utility model of a high-efficiency dewatering device for secondary pressure filtration of turbid circulating water in steelmaking is as follows:

[0042] First, the dewatering control module controls the electric push rod 31 of the inlet connector 3 to connect the water supply pipe 32 to the water delivery tank 9. Then, the dewatering control module controls the control motor 41 of the electromagnetic water guide valve 4 to rotate the water guide seat 42, opening the water delivery channel. The turbid circulating water from steelmaking to be treated flows into the water delivery tank 9 through the inlet connector 3, and then into one of the plate and frame filter press components 5. Simultaneously, the dewatering control module activates the hydraulic system to apply pressure to the plate and frame filter press component 5 for secondary pressing and dewatering. The water produced during dewatering flows into the drainage tank 6 and is discharged... The water seal strip 7 prevents water leakage. When the plate and frame filter press assembly 5 completes dewatering, the dewatering control module controls the drive motor 21 of the rotating bracket 2 to operate, which drives the tilting fixing frame 23 to rotate through the pulley group 22, so that the plate and frame filter press assembly 5 that has completed dewatering moves to the unloading position. At the same time, another plate and frame filter press assembly 5 moves to the water inlet position, and repeats the above water inlet and filter press process. When draining, the dewatering control module controls the adjusting motor 101 of the adjusting baffle 10 to rotate the sealing plate 102, open the outlet hole 8, and drain the water in the drainage tank 6.
