Description

Technical Field

[0001] This utility model relates to the field of filter presses, and in particular to a filter press working system. Background Technology

[0002] Currently, there are various types of coal slime on the market. Depending on the different mineral compositions of the coal slime, the corresponding filter presses and their process parameters also differ. If the parameters are incorrect, it will directly affect the filtration effect. Moreover, even if the material source is the same, the parameters will still fluctuate between different batches of material.

[0003] In existing technologies, acquiring relevant data requires a significant amount of manpower and time. Furthermore, manual sampling and testing can lead to data loss and contamination, while also increasing the workload for operators and impacting production efficiency. Particularly problematic is the inability to adjust the filtration process promptly when parameters fluctuate significantly in real time, resulting in poor filtration performance. Currently, there is a lack of corresponding solutions to this issue. Utility Model Content

[0018] The feeding unit includes a feeding pipe 1, which is connected to an upstream slurry pump for pumping in materials;

[0019] A feeding detection unit 2 is provided on the feeding pipe 1. The feeding detection unit 2 includes a particle size detector, a viscometer, and a hydrometer; the effect of this is to detect the parameters of the material in real time.

[0020] The feeding pipe 1 is connected to the coal slime mixing tank 5; that is, the uniformity of the material is ensured by the mixing of the coal slime mixing tank 5.

[0021] The coal slime mixing tank 5 is also equipped with an automatic dosing unit 6;

[0022] The coal slime mixing tank 5 is connected to the filter press via the filter press feeding pipe 4; the output unit of the filter press is equipped with an output detection unit 7.

[0023] The effect achieved is that the real-time parameters of the feeding detection unit 2 and the output detection unit 7 are used to adjust the process of the filter press host 8 in response to ensure stable material output.

[0024] In Example 1, a filtration system 3 is also provided between the feeding pipe 1 and the coal slime mixing tank 5.

[0025] This achieves the effect of coarse filtration of materials, preventing materials with excessively large particles from entering the filter press stage.

[0030] Preferably, the feeding pipe is also equipped with a pressure gauge, a vent valve and a water flushing pipe.

[0031] This ensures production safety and stable material feeding.

[0032] In Example 4, the filter press main unit 8 is also connected to the coal slime mixing tank 5 through a return pipeline.

[0033] The effect achieved is that the material in the backflushing pipe falls back into the material cylinder, avoiding pipe blockage and other issues.

[0035] The effect achieved is multi-unit linkage, controlling the filter press to adjust the process response.

[0036] In Example 6, the filter press main unit 8 is further provided with a secondary filter press unit, which includes a pressing water tank 9. The pressing water tank 9 is connected to the filter membrane in the filter press main unit 8 through a medium conveying pipeline, and the filter membrane is connected to the pressing water tank through a return water pipeline.

[0037] Preferably, the medium conveying pipeline connects two feeding branches, and each feeding branch is equipped with a medium conveying pump.

[0038] Example 7. The filter press main unit 8, the feeding unit, the output detection unit 7, and the secondary filter press unit are controlled collaboratively by the central control system.

[0039] Preferably, the central control system is one of PLC, MCU or microcomputer.

[0040] The effect achieved is that, through the coordinated control of the main control system, the filter press host 8 flexibly adjusts the filter pressing process based on the feedback from the feeding detection unit 2 and the output detection unit 7, and coordinates with the dosing unit and the media delivery pump to ensure stable output of the filter press.
