Russian Automatic Plate Shifter VS Manual Plate Shifter of Filter Press
An automatic plate shifter filter press is a filter press equipped with an automatic plate shifter system. It automatically pulls the filter plate open through hydraulic, motor, or pneumatic devices, reducing manual intervention and improving work efficiency.
Working Principle
The filter plate is tightly pressed under the action of the hydraulic system, and the feed pump transports the slurry to the filter chamber for solid-liquid separation. After the filtration is completed, the system starts the automatic plate shifter mechanism, pulls the filter plates open in turn, and the filter cake falls off by gravity or vibration assistance; the filter plate automatically resets after being pulled open, ready for the next cycle.
Automatic Plate Shifter VS Manual Plate Shifter
Automatic plate shifter
The filter plates of the filter press can be opened automatically one by one or multiple plates can be pulled open at the same time, which saves effort in unloading the filter cake. High working efficiency, fast filter plate pulling speed, reduced intermittent time, and improved processing capacity. Suitable for large-scale, continuous operation conditions.
Especially suitable for harsh environments. The operator is relatively far away from the site and spends less time. Suitable for large-scale industrial production, such as chemical, metallurgical, mining, sewage treatment, and other industries that require high-efficiency filtration.
The automatic plate-pulling machine automatically pulls the filter plate open and close through the hydraulic system, motor, or pneumatic device. It is generally managed by the PLC control system, and the program can be set to execute automatically. The plate pulling time, unloading delay, and other times can also be adjusted through the time relay.
The automatic plate shifter basically does not require manual intervention. The operator only needs to monitor the operation of the equipment, which greatly reduces the labor intensity.
The cost of automatic plate pulling equipment is relatively high, mainly including automatic plate pulling mechanism, electronic control system, etc., but in the long run, it can reduce labor costs and improve production efficiency.
Compared with manual operation, the automatic plate shifter is slightly more likely to fail, and there will be corresponding maintenance costs, but the economic benefits are higher from the perspective of long-term interests.
Manual plate pulling
The manual plate pulling is done by the operator manually pushing or pulling the filter plate to open and close, and the entire process is completed by manpower. Two people are required to pull and move the filter plates on both sides of the machine at the same time to unload the filter cake, which is relatively labor-intensive.
The manual plate pulling operation is slow, and the filter plates need to be pulled open one by one and the filter cake needs to be unloaded manually with a discharge shovel, which takes a long time and is suitable for small or intermittent operations.
Manual plate pulling requires the full participation of operators, and the labor intensity is high. Especially when there are a large number of filter plates or a large amount of equipment, the workload increases significantly. It is suitable for small operations, such as laboratories, small sewage treatment plants, or occasions with low-efficiency requirements.
The manual plate-pulling equipment has a simple structure and low cost and is suitable for enterprises with limited budgets or small processing volumes.
The plate pulling time and slag unloading time can be controlled by workers (speed and pause), which is flexible and free.
Compared with automatic plate shifters, the probability of failure and problems of manual plate pulling is almost zero.
Conclusion
Automatic plate shifter and manual plate pulling have their own advantages, and you can choose according to your needs. If the company wants to improve production efficiency and reduce labor input, the automatic plate-pulling filter press is a better choice; if the budget is limited or the production capacity demand is not high, the manual plate-pulling filter press is also an economical and applicable solution.
