Furthermore, the drain pipe and the liquid inlet pipe are both welded on the intermediate tank, and the outer end of the drain pipe and the lower end of the liquid inlet pipe are respectively provided with a flange plate for connecting other pipelines.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings needed to be used in the embodiments will be briefly described below, and obviously, the drawings in the following description are only embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts;

fig. 1 is a schematic structural view of a specific embodiment of a drainage structure for a prestressed steel strand production plant.

In the figure: 100-centrifugal pump, 200-intermediate tank, 210-liquid outlet pipe, 220-liquid inlet pipe, 230-flange plate, 300-pipeline and 400-water storage tank.

Detailed Description

In order to make the technical purpose, technical solution and advantageous effects of the present invention clearer, the technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

Drainage structure for prestressing force steel strand wires workshop, as shown in fig. 1, including centrifugal pump 100 that is arranged in taking liquid in the tank 400 away and the pans 200 of setting in the tank 400 top, centrifugal pump 100 is current equipment, pans 200 are the cylinder structure, pans 200 are supported in the tank 400 top by the support frame, and be vertical state, be equipped with the drain pipe 210 that a level set up on the lateral wall of pans 200, the pans are connected to drain pipe 210 one end, centrifugal pump 100's import is connected to the other end, the pans 200 bottom is equipped with the feed liquor pipe 220 of a vertical setting, the pans 200 are stretched out to feed liquor pipe 220 lower extreme, feed liquor pipe 220 upper end stretches into the pans and the upper end is higher than drain pipe 210, the lower extreme of feed liquor pipe 220 passes through ring flange 230 connecting tube 300, pipeline 300 stretches into tank 400.
