Supporting device for cloth supporting roller of belt filter

Technical Field

The utility model relates to a belt filter technical field, concretely relates to belt filter is strutting arrangement for fabric supporting roller.

Background

The belt filter is a novel filtering device with higher automation degree, takes filter cloth as a medium, realizes solid-liquid separation of slurry on the filter cloth through gravity and vacuum fine particles, and is widely used in wet-process phosphoric acid production. The core component of the belt filter is filter cloth, the filter cloth circularly moves according to a set route under the action of the power roller and the tension roller, in order to avoid the phenomenon that the filter cloth sags due to self gravity and causes uneven tensioning of the filter cloth due to speed difference, a plurality of cloth supporting rollers are arranged below the lowest position of the filter cloth in parallel, two ends of each cloth supporting roller are rotatably connected with the stand column of the frame through bearings, and the filter cloth drives the cloth supporting rollers to rotate through friction in the advancing process. The condition that the cloth supporting roller shaft is broken can occur in the using process, and the cloth supporting roller shaft is difficult to find in time because the cloth supporting roller shaft is positioned at the lowest part of the whole filtering equipment and can be found in the regular maintenance and overhaul process generally. The filter cloth droops because of the gravity after the carrier cloth roller breaks, can appear leading to the inhomogeneous condition of tensioning degree because of the speed difference in the filter cloth motion process, finally leads to the filter cloth to be torn, and it wastes time and energy and is expensive to change the filter cloth. Therefore, it is necessary to develop a cloth supporting device for a belt filter to solve the problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a belt filter holds in palm cloth roller strutting arrangement solves current belt filter and leads to the torn problem of filter cloth because of the fracture of holding in the palm cloth roller pivot is not in time discover.

In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a belt filter is strutting arrangement for fabric supporting roller which characterized in that: the cloth supporting roller comprises a fixed base, roller fixing frames and rollers, wherein the fixed base is composed of two straight rods arranged in parallel, one ends of the straight rods are welded on two sides of a stand column of the filter, a connecting plate is arranged at the top of the other end of each straight rod, the two roller fixing frames are arranged above the connecting plate in parallel, the rollers are arranged on the roller fixing frames, and the rollers are in contact with the outer side wall of a cloth supporting roller of the filter.

The technical scheme is that a vertical rod is vertically arranged at the top of one end, close to the upright post, of the straight rod, and the vertical rod is provided with a fixing hole which is fixed on the upright post through a fastener.

A reinforcing rod is arranged between the vertical rod and the straight rod.

A connecting rod is arranged at one end, far away from the upright post, of the straight rod.

The roller fixing frame is further characterized by comprising a bottom plate and a fixing plate, wherein the bottom plate is fixed on the connecting plate, the fixing plate is oppositely arranged on the bottom plate, a U-shaped shaft hole is formed in the top of the fixing plate, and a rotating shaft of the roller is fixed in the U-shaped shaft hole.

The working principle is as follows: when the filter cloth is used, the fixed base is fixed on the upright post of the filter, the position is adjusted to ensure that the idler wheel is just contacted with the cloth supporting roller, the cloth supporting roller is driven to rotate by the direct friction force between the cloth supporting roller and the filter cloth in the advancing process, and the idler wheel is driven to rotate by the friction force between the cloth supporting roller and the idler wheel in the rotating process of the cloth supporting roller. Effectively support the cloth supporting roller, prolong its life, when the fracture appears in cloth supporting roller both ends pivot, hold the cloth supporting roller, guarantee the normal motion of filter cloth in the short-term, avoid equipment unplanned parking number of times, guarantee whole apparatus for producing's normal operating.

Compared with the prior art, the beneficial effects of the utility model are that: the supporting device for the cloth supporting roller of the belt filter is simple in structure, the idler wheel for supporting is arranged below the cloth supporting roller, the phenomenon that a rotating shaft of the cloth supporting roller is broken due to uneven stress or overlong service time is avoided, the service life of the cloth supporting roller is greatly prolonged, meanwhile, when the rotating shaft of the cloth supporting roller is broken, the cloth supporting roller is effectively supported, normal movement of filter cloth in a short period is guaranteed, the number of times of unplanned stop of the belt filter is avoided, and normal production is guaranteed. The supporting device is fixed on the upright post through the straight rod, the upright post is further fastened, the strength between the upright post and the straight rod is increased through the reinforcing rod, and the straight rod is prevented from deforming under stress; the rollers are fixed through the U-shaped shaft holes, so that the rollers are convenient to disassemble and assemble, and the maintenance and the overhaul are convenient.
