Preferably, a back washing device is further arranged on the water return pipe, the back washing device comprises back washing pipelines, and the end of each back washing pipeline extends into the upper end of the spray water recovery device.

Compared with the prior art, the detailed description of the application is as follows:

the application discloses kind of shearing machine automatic spray cooling system is through spraying the cooling to the shearing machine tap hole for steel rod that the tap hole was cuted and is sent out in time cool down, has reduced the steel temperature, avoids the phenomenon of blackening because of steel oxidation leads to, has guaranteed shearing quality and production stability.

Drawings

Fig. 1 is a schematic structural diagram of the system.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following detailed description is made with reference to the accompanying drawings and specific embodiments.

As shown in the figure, an automatic spray cooling system of shears is arranged at a steel tapping hole of the shears.

This cooling system includes spray header (1), spray header (1) sets up in the top of the steel-tapping hole of shearing machine, and when the steel-tapping of shearing machine, spray header (1) spray water smoke downwards, cools down the steel that the shearing machine was cuted.

Be provided with temperature-detecting device (2) above the tap hole, temperature-detecting device (2) are infrared temperature-detecting device, temperature-detecting device (2) are used for detecting the temperature field of steel that the tap hole department sheared the seeing off, temperature-detecting device (2) are connected automatically controlled valve (3) on spray header (1), and the temperature of the steel that detects as temperature-detecting device (2) is higher than the settlement temperature, and automatically controlled valve (3) receive the signal of telecommunication, open valve , and spray header (1) begins to spray.

The spray water is a saline solution with the concentration of 5% or an aqueous solution containing 5-8% of quenching liquid, and because the temperature is too high when the steel is sheared, a bluish black surface is easily formed on the surface, so the spray water is the saline solution or the solution with constant-concentration quenching liquid, the spray water can carry out proper quenching treatment on the high-temperature steel surface, and the problems that the austenite is changed into martensite on the steel surface due to chilling and fine cracks are generated due to stress change are avoided.

Be provided with spray water recovery unit (5) under spray pipe (1), the bottom of spray water recovery unit (5) is domatic, because spray water when spraying steel surface, probably has smugglied solid particle thing secretly, or makes the oxide skin on steel surface drop, gets into spray water recovery unit (5), makes solid particle thing deposit at the low level through domatic.

The bottom of shower water recovery unit (5) is provided with wet return (4), and wet return (4) insert in the relatively higher side in the bottom position of shower water recovery unit (5), wet return (4) are connected to through circulating pump (9) shower pipe (1) because solid particulate matter deposit is in domatic bottom for wet return (4) are difficult for blockking up, in addition, still be provided with filter screen (6) on wet return (4), filter screen (6) are detachable metal filters (6), filter screen (6) are used for preventing solid particulate matter from following wet return (4) inflow pipeline, still be provided with reverse flushing device on wet return (4).

The water return pipe (4) is further provided with a back flushing device, the back flushing device comprises back flushing pipelines (9), flushing pumps (7) are arranged on the back flushing pipelines (9), the end of each back flushing pipeline (9) extends to the upper end of the spray water recovery device (5), the back flushing pipelines (9) can extract relatively clean water from the top, the back flushing is conducted on the water return pipe (4) at the bottom, solid particles attached to a metal filter screen (6) accumulated at the tail end of the water return pipe (4) are removed, a stop valve (8) is further arranged on the water return pipe (4), the stop valve (8) is arranged at the end of far away from the spray water recovery device (5), when the back flushing is needed, the stop valve (8) is closed, and the back flushing water sent by the water return pipe (4) flows into the spray water recovery device (5).
