Description

Technical Field

[0001] The utility model relates to the field of water quenching, in particular to a yellow phosphorus slag water quenching slag flushing tank. Background Art

[0002] In nature, phosphorus compounds are widely distributed. The earth's crust contains about 0.142% of phosphorus compounds, which mainly exist in minerals in the form of phosphates. At present, the main methods of extracting phosphorus include electric furnace method, blast furnace method, plasma method and fluidized bed reduction method, among which the electric furnace method is the most commonly used. After the electric furnace method is used for refining, a large amount of slag will be produced. In order to facilitate the recovery of the slag, the yellow phosphorus slag is usually subjected to water quenching.

[0003] The existing yellow phosphorus slag water quenching usually uses a slag conveying device to transfer the high-temperature slag, and a water flushing device is set at the discharge port of the slag conveying device to break up and cool the slag through the water flushing device. In order to facilitate the transportation of the slag, a slag flushing trough with a slope is usually set under the water flushing device to transport the slag to the slag flushing pool for slag-water separation. In order to recycle water resources, a pressure pump device is usually set next to the water flushing device and the slag flushing pool to circulate water resources.

[0004] Most of the existing slag flushing trough mechanisms are multi-structure welded into an integrated structure. Although this ensures that the slag flushing trough will not leak, it is difficult to disassemble. If it is disassembled violently, the slag flushing trough is likely to be damaged. Utility Model Content

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is as follows: a yellow phosphorus slag water quenching slag trough, comprising a slag conveying device, a slag trough mechanism and a slag trough pool, the discharge port of the slag conveying device is connected to the inlet of the slag trough mechanism by welding, a water flushing device is provided on one side of the discharge port of the slag conveying device, the water flushing device is connected to the slag trough pool by a pressure pump device, the slag trough pool is located below the slag trough mechanism, the slag trough mechanism comprises an inlet slag trough welded to the discharge port of the slag conveying device and a plurality of slag trough sub-troughs, the inlet A slope bracket for fixing is provided below the entrance slag flushing trough and the slag flushing trough sub-trough, and a plurality of fixed columns are provided on the supporting surface of the slope bracket, and the fixed columns pass through the connecting surface of the slag flushing trough sub-trough. A fixed A step groove and a fixed B step groove are respectively provided on both sides of the slag flushing trough sub-trough, and the notch of the fixed A step groove is opposite to that of the fixed B step groove, and the notch of the fixed A step groove is located at the inner wall end of the inlet of the slag flushing trough sub-trough, and a fixed B step groove is provided at one end of the outlet of the entrance slag flushing trough, and the fixed A step groove is connected with the fixed B step groove through body contact.

[0007] As an improvement, a spare slag flushing trough for extension is provided on one side of the discharge port of the slag flushing trough sub-trough located at the bottom of the slope bracket, and a support plate corresponding to the spare slag flushing trough is provided below the spare slag flushing trough.

[0008] As an improvement, the spare slag flushing trough and the discharge port of the slag flushing trough sub-trough as well as the support plate and the slope bracket are all connected by welding.

[0009] As an improvement, a foldable protective baffle is provided above the slope bracket to prevent slag from splashing, and a gas collecting device for collecting waste gas inside the slag flushing trough mechanism is provided on one side of the foldable protective baffle. The gas collecting device is connected to the gas outlet above the foldable protective baffle through a gas collecting pipe.

[0010] As an improvement, the interior of the foldable protective baffle is provided with a plurality of U-shaped frames for supporting the foldable protective baffle, and fixed sliders are provided at the open ends of the U-shaped frames.

[0011] As an improvement, a positioning plate is provided on one side of the fixed sliding block, and the positioning plate is connected to the connecting plates on both sides of the slope bracket through a pin structure.

[0012] The advantages of the utility model compared with the prior art are: the device is connected by the body contact of the fixed A step groove and the fixed B step groove, and because the groove of the fixed A step groove is located at the inner wall end of the slag flushing trough feed port, when the slag is flushed out, part of the water splash will not flow back into the gap between the fixed A step groove and the fixed B step groove, and because of the slope of the slope bracket, it can be ensured that the water quenching solution in the slag flushing trough will not remain, and the slag flushing trough mechanism will not leak; because of the sliding connection between the fixed column and the slag flushing trough through hole, the slag flushing trough can be freely disassembled.
