AI Technical Summary

Technical Problem

The existing automatic filter presses are inefficient during the unloading process and lack the automatic auxiliary mud unloading function, which makes it difficult for filter cakes with strong viscosity to fall off on their own, and require manual cleaning, resulting in the equipment becoming semi-automatic, with low cycle production efficiency and high labor intensity for personnel.

Method used

A grouping pulling mechanism is used to connect multiple filter plates in series to form a filter plate group through the connecting components. The filter plate is vibrating and blasting the filter plate to achieve the vibration and knocking of the sludge on the filter plate, and the weight sensor is used to determine whether there are filter cake residues on the filter plate, and the mud unloading process is automatically adjusted.

Benefits of technology

It significantly improves the sludge unloading efficiency of the filter press, avoids the need for manual cleaning, reduces the equipment failure rate and operating costs, and improves the equipment automation and production efficiency.

Abstract

The invention discloses an automatic filter press utilizing grouped pull plates to assist in mud unloading and a mud unloading control method, the automatic filter press comprises a filter plate and pull plate mechanisms symmetrically arranged on two sides of the filter plate, and each pull plate mechanism comprises a pull plate trolley, a connecting assembly, a handle, a rapping assembly and a slide rail driving assembly; the handles are symmetrically arranged on the two sides of the filter plates, and the connecting assemblies are arranged on the sides of the handles in the moving direction of the filter plates so that at least two filter plates can be connected in series to form a filter plate set; the plate pulling trolley and the rapping assembly are both arranged on the sliding rail driving assembly, the plate pulling trolley is connected with a handle on the side portion of a first filter plate in the filter plate set in a hanging mode, when the plate pulling trolley pulls the first filter plate in the filter plate set to move, the connecting assembly drives the other filter plates to move along with the first filter plate, and when all the filter plates are pulled by a preset distance, the rapping assembly drives the filter plates to ascend and descend. Therefore, the filter plate is vibrated and unloaded. The filter press has the characteristics of compact structure, convenience in operation, high stability and the like, can realize vibrating and mud unloading of multiple filter plates at the same time, and improves the working efficiency of the filter press.
