Description

Sand unloading door of filter press box type pier column and modular stacked steel structure box type pier column

Technical Field

The invention belongs to the technical field of supporting facilities of a movable filter press (patent classification number B01D 25/12), and relates to a semi-automatic sand discharge door of a modular laminated steel structure box type pier column, which can be moved and reused.

Background

The filter press is a pressurized filtering device with multiple filtering chambers operated intermittently; a movable filter press is a filter press which can be repeatedly disassembled, moved and transferred to a new construction site (commonly called as a transition site) in a short period of time and is convenient to install and utilize, namely, components which need to be disassembled and transported have detachability; the filter mainly comprises a double-beam frame, a filter plate pressing mechanism, a multi-filter-chamber filtering mechanism, a plate pulling and cake unloading mechanism, a filter cloth cleaning mechanism, a liquid receiving and plate turning mechanism and a PLC program control system; the supporting facilities of the movable filter press comprise filter cake transportation equipment (namely a filter cake transportation truck or a filter cake conveyor belt mechanism) and filter press piers; the solid-liquid separation of various suspensions (i.e. mixtures of liquid and solid particles) suitable for mobile construction sites.

The filter press pier column is similar to a pier which is used in a disposable long-term fixed mode and can not be detached and reused, mainly comprises a reinforced concrete structural formula and a non-reusable steel structure which are integrated, the height of the filter press pier column is larger than that of filter cake transportation equipment, and the width of the filter press pier column corresponds to that of two support legs of a filter press; the device is used for installing a filter press at a high position and ensuring that the filter cake transportation equipment has enough operation space, and is not suitable for the transition recycling of the movable filter press. The filter press and the matched facilities thereof have the following relationship: the filter press is arranged on the double pier columns, and the filter cake transportation equipment is positioned below the filter press; the working process of the filter press is as follows: the feeding pump pressurizes and inputs the material into the filtering chamber through the feeding hole, low-pressure static filtration is carried out, particles in the material are intercepted by the filter cloth to form a filter cake in the filtering chamber, the filtrate passes through the filter cloth and flows out of the liquid outlet hole of the filtering chamber, the filter plate is pulled open to realize gravity cake unloading, and the filter cake falls onto the filter cake conveying equipment.

The existing disposable filter press pier column has the following defects: the existing reinforced concrete structural type or integral (integrated) steel structure type filter press pier stud is a disposable long-term fixed-use non-detachable and reusable facility and cannot be recycled along with a mobile filter press, so that not only is the waste of matched facilities caused, but also the occupied site influences the environment, and the requirement of short-term flow operation in the industries such as piling industry, dredging industry, wastewater treatment and the like cannot be met, once the filter press is transferred, repeated investment is required to construct the filter press pier stud, the construction difficulty of constructing the pier stud on site is higher, the construction period is long, and the transfer reuse cost is high; the user of the movable filter press urgently needs a matched movable pier column, which is a technical problem that people are eagerly to solve but are always unsuccessful.
