[0026] Example 1

[0027] See also Figure 1-5A kind of economical and environmentally friendly non-powered chute for coke, including a bottom plate 1 and a screen box 2, crossbeam seats 8 are fixedly installed on the front and rear sides of the inner cavity of the screen box 2, a crossbeam body 7 is fixedly installed on the top of the crossbeam seat 8, an adjusting groove 16 is opened on the top of the crossbeam body 7, a connecting bolt 12 is arranged on the inner side of the adjusting groove 16, a bolt-fixed pipe seat 10 is fixedly installed on the top of the crossbeam body 7 through the connecting bolt 12, a T-shaped movable groove 11 is opened at one end of the bottom of the bolt-fixed pipe seat 10, a supporting square tube 6 is welded to the top of the bolt-fixed pipe seat 10, a saddle-shaped alumina corundum ceramic strip 5 is bonded to the top of the supporting square tube 6, a through hole 13 is opened on the inner surface of the saddle-shaped alumina corundum ceramic strip 5, a series of round steels 14 are arranged on the inner side of the through hole 13, and a clamping plate 9 is fixedly connected to the left and right sides of the supporting square tube 6.

[0028] A screen box 2 is fixedly mounted on the top of the bottom plate 1 , and a feed port 3 is provided at the right end of the top of the screen box 2 .

[0029] Through the above technical solution, the setting of the feed port 3 facilitates the entry of coke.

[0030] The lower end of the right side of the screen box 2 is movably connected to a sealing door 4 through a hinge, and a handle is fixedly installed at one end of the sealing door 4.

[0031] Through the above technical solution, the sealing door 4 is provided to facilitate the removal of the screened material.

[0032] There are multiple supporting square tubes 6 , and the distance between two adjacent supporting square tubes 6 is equal.

[0033] Through the above technical solution, the saddle-shaped alumina corundum ceramic strip 5 can be supported by setting the supporting square tube 6.

[0034] There are two cross beam seats 8 in a group, and the cross beam seats 8 in each group are distributed in a stepped manner.

[0035] Working principle: when the material is put into the screen box 2 through the feed port 3 during use, the material can pass through multiple saddle-shaped alumina corundum ceramic bars 5 in turn to achieve the ability of unpowered screening. When it is necessary to adjust the spacing (the spacing determines the particle size of the screened material) and the opening (the discharge end is slightly larger than the feed end opening along the material flow direction, which is convenient for the material to pass through the screen gap and is not easy to get stuck when passing through the mesh, and improves the mesh penetration rate), with the cooperation of the crossbeam 7 and the bolt-fixed pipe seat 10, the connecting bolts 12 are loosened. When the connecting bolts 12 slide in the adjusting groove 16, and with the assistance of the T-shaped movable groove 11, the supporting square tube 6 and the saddle-shaped alumina corundum ceramic bars 5 can be driven to move through the bolt-fixed pipe seat 10, thereby realizing the rapid adjustment of the spacing and opening of the saddle-shaped alumina corundum ceramic bars 5.

[0036] Example 2

[0038] Working principle: When in use, an adjustment pad 15 with a matching inclination angle is inserted between the crossbeam seat 8 and the crossbeam body 7 as needed, so that the crossbeam body 7 can be inclined after installation, making it convenient for people to quickly adjust the screen surface inclination of the non-powered chute as needed (the positive and negative changes in the screen surface inclination can adjust the total amount of screening).

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
