Description

Technical Field

[0001] The utility model relates to the technical field of humic acid fertilizer production, in particular to a raw material screening mechanism for producing humic acid fertilizer. Background Art

[0002] Humic acid fertilizers, also known as humic fertilizers, are organic fertilizers rich in humic acid and a certain amount of inorganic nutrients. These fertilizers are made primarily from peat, lignite, and weathered coal, processed through various processes, and blended with a certain amount of inorganic fertilizer. Humic acid is a group of black or brown, colloidal, amorphous, high-molecular-weight organic compounds containing elements such as carbon, hydrogen, oxygen, nitrogen, and sulfur. Humic acid has a large internal surface area, resulting in excellent adsorption, adhesion, and colloidal dispersion, as well as a high cation exchange capacity.

[0003] The prior art discloses a raw material screening device for producing humic acid fertilizer with application number CN202022308051.4, comprising a support frame, a screening mechanism for screening humic acid-containing waste raw materials fixed on the top of the support frame, a fixing mechanism fixed to one end of the screening mechanism, the screening mechanism comprising a spring, a vibration box, a vibration motor, a chute, a vibrating screen and a sieve hole, a spring symmetrically fixed to the top of the support frame, a vibration box fixed to the top of four of the springs, a vibration motor fixed to the middle of the lower surface of the vibration box, chute symmetrically opened on both sides of the inner wall of the vibration box, the inner walls of the two chutes are slidably connected with a vibrating screen, and the top of the vibrating screen is equidistant It is provided with sieve holes, and the fixing mechanism includes a sliding hole, a fixing plate, a screw, a threaded sleeve, a pressure plate and a motor.
