Abstract

The utility model relates to a multi-purpose solid-liquid separation cylinder, which is shaped by welding metal perforated plates. A screen bar is vertically welded on a screen pipe head, the flat surface of the screen bar faces inwards and the convex surface faces outwards, and bars for fixing the gaps of the screen bar is welded on the convex surface of the screen bar to shape a web cylinder. The screen pipe head is welded on the two ends of the web cylinder in order to improve the strength of the web cylinder. Reinforcement bars are vertically welded outside a cylinder after the cylinder is shaped. Materials can be chosen from common steel or alloyed steel according to use conditions. The screen pot is mainly applicable to the solid-liquid separation in sewage disposal.

Description

Multipurpose Separation of Solid and Liquid screen drum

The utility model relates to a kind of multipurpose Separation of Solid and Liquid screen drum, is used in particular for the device of the Separation of Solid and Liquid in the wastewater treatment.

At the big filter cylinder of usefulness, adopt woven wire cloth to add skeleton at present, its shortcoming is that intensity is low, fragile, service life short, inferior separating effect more.

For addressing this problem, Chinese patent ZL98211343.9 multipurpose particle separation screen drum, normally adopt horizontal boxing of grating or laterally sieve plate welding moulding, because grating is when using laterally, the upper surface of grating easily amasss thing and stops up the sieve seam, causes decline, pressure rising, energy consumption increase, the separating effect variation of disposal ability.

The purpose of this utility model is that the horizontal moulding of the grating of screen drum is changed into the vertical moulding of grating, promptly the horizontal boxing or the welding of grating, change the vertical welding of grating into, significantly reduce the horizontal table area of grating after this improvement, prevent that effectively grating top surface area thing from stopping up, and keeps filtering net cleaning, prolong backwashing period, disposal ability does not reduce, and pressure does not raise, energy consumption does not increase, separating effect variation not, and a kind of multipurpose Separation of Solid and Liquid screen drum of new structure is provided for Separation of Solid and Liquid.

Technical solution of the present utility model is, a kind of by metal sieve plate welding moulding, grating (3) is vertical welding, the plane of grating at the lining convex surface outside, be welded with the rib (4) of gravity flow screen interspace on the grating appearance convex surface, after the moulding of net tube, net tube two ends are welded with reinforcing joint (1), for improving the intensity of net tube, the outer reinforcement (2) that vertically is welded with of tube after the cylindrical shell moulding.

Advantage of the present utility model is that grating is vertical, and isolated foul can slide to the end down, and the not long-pending thing in grating surface stops up, keeps disposal ability not reduce, and backwashing period is long, energy consumption is low, good separating effect.

Description of drawings:

Fig. 1 is the assembly drawing of utility model; Fig. 2 is the transversal profile of assembly drawing; Fig. 3 is a rib transversal profile structure chart; Fig. 4 is grating and reinforcement transversal profile structure chart; Fig. 5 is that structure chart cuts open in the office of screen casing head.

Screen casing head (1); Reinforcement (2); Grating (3); Rib (4).

Embodiment:

It is like the △ type that the utility model is selected grating (3) for use, grating (3) vertically is welded on the screen casing head (1), the plane of grating at the lining convex surface outside, the baseplane width range of grating is 0.5～15mm, the altitude range of grating is 0.8～30mm, and vertical top sieve gap scope is 0.1～50mm.The rib of gravity flow screen interspace (4) is a ladder type, and rib bottom width degree is 1～20mm; Highly be 1.5～30mm, 1～180 of quantity is uniform, and rib is vertical with grating (3), rib and the flat shape of screen casing head (1); Vertically be welded with reinforcement (2) on the rib outside tube (4), both angles are 90 °; Reinforcement (2) is square, rectangle, triangle or circular four kinds, the span of the length of side, height or diameter is 3～100mm, 2～360 of quantity are uniform, multipurpose Separation of Solid and Liquid screen drum after the moulding vertically uses, isolated long-pending thing can slide to the end down, keep filtering net cleaning, prevent that effectively the top surface area thing of grating from stopping up, it is good especially to use effect.
