[0033] In order to make the technical means, creative features, purposes and effects achieved by the present application easy to understand, the present application will be further described below in conjunction with specific drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, not all.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0035] As shown in Figures 1 to 5 The spraying liquid distribution device of the present application comprises a spraying pipe 1, a head end sleeve 2, a tail flange seat 3, a sealing ring 4, a tail flange cover 5 and a spraying tank 6. The spraying tank 6 comprises a tank body plate 6a and a tank body end plate 6b. The bottom of the tank body plate 6a is connected in a V shape, and the tank body end plate 6b is connected to the two ends of the tank body plate 6a. The above is welded and fixed into a tank body. An arc-shaped notch is provided on the upper middle part of the tank body end plate 6b for embedding the spraying pipe 1.

[0036] A splash-proof connecting seat 6c is symmetrically welded on the inner wall of the upper part of the tank body end plate 6b. The splash-proof connecting seat 6c is a short angle steel, with a horizontal section on the top and a vertical wall extending downward. A splash-proof baffle 6d is fixed on the splash-proof connecting seat 6c. The splash-proof baffle 6d is a long angle steel, extending along the length direction of the spraying tank 6 and fixed on the splash-proof connecting seat 6c at both ends.

[0037] A tank body connecting seat 6e extending vertically is welded on both sides of the outer wall of the tank body end plate 6b. The tank body connecting seat 6e is fixed on the wall plate of the leaching device by bolts.

[0038] A row of round holes is opened in the bottom of the spraying pipe 1. A circular arc baffle 1d is provided on the lower side of each round hole. The cross section of the circular arc baffle 1d is a semicircular arc, and the opening end of each circular arc baffle 1d faces the inlet end of the spraying pipe 1. The upper end of the circular arc baffle 1d is inserted into the spraying pipe 1 by a certain height, which forms an obstruction to the solvent flowing towards the tail end, so that the solvent is diverted to be sprayed out of the round hole, avoiding the phenomenon of too small flow in the upstream round hole. The closer to the head end of the spraying pipe 1, the higher the insertion height of the circular arc baffle 1d, so that the liquid distribution along the length direction of the spraying pipe 1 is more uniform.

[0039] The lower end of the circular arc baffle 1d extends out of the bottom of the spray pipe 1 by a distance of 1 / 4-1 / 3 of the outer diameter of the spray pipe 1, so that the solvent sprayed from the circular hole flows vertically downward, avoiding the solvent flowing obliquely from the liquid surface of the spray tank 6 to the tail end, and making the liquid level at the head and tail ends of the spray tank 6 more balanced.

[0040] The spray pipe 1 is welded with a spray pipe connecting flange 1c near the outer periphery of the head end, the head end of the spray pipe 1 is welded with a tee 1a, the horizontal outer port of the tee 1a covers the head end flange cover 1b, and the downward port of the tee 1a serves as a liquid inlet.

[0041] During installation, first, the head end sleeve 2 and the tail flange seat 3 are respectively installed on the box wall plates on both sides of the extractor, then the spray pipe 1 is passed through the head end sleeve 2 and the tail end is passed out of the tail flange seat 3, the spray port of the spray pipe 1 is vertically downward; then the sealing ring 4 is installed, the tail flange cover 5 is installed on the tail flange seat 3, and the lip of the sealing ring 4 is embedded between the tail end of the spray pipe 1 and the tail flange seat 3; then the spray tank 6 is placed directly below the spray pipe 1, and the spray port of the spray pipe 1 is vertically downward against the bottom of the spray tank; the spray tank 6 is fixed on the box wall plates on both sides of the extractor through the tank body connecting seats 6e at both ends.

[0042] The upper edges of the two side tank body plates 6a are respectively provided with sawtooth grooves 6f in the full length direction, and the sawtooth grooves 6f on both sides are staggered.

[0043] The solvent enters from the middle port of the tee 1a, flows to the tail end along the spray pipe 1, is blocked by each circular arc baffle 1d in the middle, and then bends downward to flow out from each circular hole, avoiding excessive solvent flowing to the tail end and improving the uniformity of the first distribution. Most of the solvent entering the spray tank 6 flows out from the two side sawtooth grooves 6f, and a small amount flows out from each deslagging hole 6g.

[0044] The spray tank 6 can not only buffer the sprayed solvent, but also uniformly distribute the flow in the entire tank body, so as to ensure that the solvent flows out uniformly from both sides and the full length direction without impact, and the spraying directly covers a wide width and a large area.
