Detailed Description

The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.

As shown in fig. 1-3, to improve the sealing performance at the joint of the grooved brick 1. The utility model provides a sodium hexametaphosphate leakage-proof discharging chute, which comprises a chute brick 1 with continuously spliced ends, wherein a chute 2 is arranged at the top in the chute brick 1, two ends of the chute brick 1 are respectively provided with a male head 3 and a female head 4, the bottom of the male head 3 is provided with an adapting bulge 5, the bottom of the female head 4 is provided with an adapting groove 10 matched with the adapting bulge 5, the end face of the adapting bulge 5 is inclined, the bottom of the adapting bulge 5 is provided with a step, two sides of the step are provided with radial limiting structures, a concave structure 9 which is contacted with the top surface of the step and realizes splicing is arranged in the adapting groove 10, and the opposite walls of the concave structure 9 and the step are provided with engagement structures.

Splicing the groove bricks 1, and connecting the female heads 4 of the previous groove bricks 1 with the male heads 3 of the next groove bricks 1 to enable the outer walls of the adapting protrusions 5 to be attached to the inner walls of the adapting grooves 10, wherein the joints are inclined and bent lines when seen from the side; the step is located the kink, and after the butt joint, the top surface of step and the interior top surface laminating of concave structure 9 pass through the step, change the vertical seam of script into horizontal seam for high temperature molten sodium hexametaphosphate is difficult for flowing from the seam, reaches the purpose that reduces the product loss and improve product quality.

The radial limiting structures are arranged on two sides, so that the situation that the abutting groove bricks 1 are not parallel to each other, and the seam on one side is enlarged to cause leakage is avoided; the engagement structure is used for limiting the relative axial movement between the butted grooved bricks 1, and also preventing the joint from being enlarged.
