Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 4, the diversion tower comprises a tower bottom surface 100 and a tower top portion 200, wherein the tower bottom surface 100 is formed by enclosing four bottom edges 110, the bottom edges 110 are in an inward concave arc shape to correspond to the inner contour of the exhaust pipe, the tower top portion 200 is projected on the tower bottom surface 100 and is located at the central point of the tower bottom surface 100, two adjacent bottom edges 110 are intersected at a connection point 120, each connection point 120 is connected with the tower top portion 200 through a separation edge 300, the bottom edges 110 and two separation edges 300 connected with the bottom edges are enclosed to form a tower surface 400, each tower surface 400 is convexly provided with a convex strip 500, and the convex strip 500 is located on the connection line of the tower top and the midpoint of the.

During the installation, the central axis of four cylindric blast pipes is arranged into the square, the central point of the bottom surface 100 of diversion tower and the central point of square put the coincidence, and the base 110 of bottom surface 100 of tower sets up with the interior contour laminating of blast pipe, make blast pipe inner wall and tower face 400 smooth transition, tower face 400 does main guide effect to exhaust emission, and when waste gas passes through tower face 400, sand grip 500 on the tower face 400 can play supplementary guide effect to exhaust emission, make exhaust emission more smooth and easy, engine exhaust efficiency is higher.

And aiming at the condition that the three exhaust pipes are arranged in a regular triangle, the bottom sides 110 of the diversion tower are three, the center of the tower bottom surface 100 is also coincided with the center of the regular triangle, and the inner walls of the exhaust pipes on the tower surface 400 are in smooth transition. Conceivably, when the number of the exhaust pipes is different, for example, 6, 8, or 12, the number of the bottom sides 110 of the guide tower and the shape of the bottom surface 100 of the tower are correspondingly changed.

Wherein, the sand grip 500 is the shape setting that both ends are narrow, the centre is wide, and sand grip 500 and tower face 400 circular arc transition for sand grip 500 is whole to be streamlined design, and the flow direction when obtaining waste gas discharge accords with aerodynamics more, and the water conservancy diversion effect is better, and the water conservancy diversion tower is lower to the resistance of waste gas.

The dividing edge 300 includes a first beveled edge 310 connected to the connection point 120, and a second beveled edge 320 connected to the tower tip 200, the second beveled edge 320 being located inwardly of the first beveled edge 310 and smoothly transitioning with the first beveled edge 310. Because the first inclined edge 310 is located outside the second inclined edge 320, the side of the tower surface 400 close to the exhaust pipe is wider, and different exhaust channels have a better separation effect, that is, the diversion tower has a better and significant effect of preventing generation of turbulent flow and turbulent flow.

The vertical distance between the top 200 and the bottom 100 is h, and the vertical distance between the center point of the bottom 100 and the bottom 110 is a, so that the diversion tower has better diversion effect when the value of h/a is 2.5 to 4.

In order to prevent the diversion tower from scratching workers, the tower tip 200 is arranged in a spherical shape, and the two arbitrary adjacent tower surfaces 400 are in arc transition, so that the diversion tower is convenient to process and assemble. The guide tower can be arranged in a solid manner or in a hollow manner. The hollow guide tower has light weight and low cost, and the hollow part of the guide tower can provide certain buffering space for high-speed airflow. And the solid diversion tower has good quality and strong stability.

In order to facilitate the positioning and installation of the diversion tower and the exhaust pipes, a positioning step 600 is convexly formed along the tower bottom surface 100, the shape of the positioning step 600 is similar to that of the tower bottom surface 100, and the edge of the positioning step 600 is attached to the outer contour of the exhaust pipes, so that the diversion tower can be embedded into gaps among the exhaust pipes through the positioning step 600, and the installation is more convenient. The position where the adjacent edges of the positioning step 600 intersect is concave, so that the phenomenon of difficult embedding caused by the clearance fit between the positioning step 600 and the exhaust pipes is avoided.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
