Description

Technical Field

[0001] The present application belongs to the field of thermal hydrolysis technology, and in particular relates to a device for preparing fertilizer by treating agricultural waste through thermal hydrolysis. Background Art

[0002] Thermal hydrolysis treatment is to hydrolyze organic waste such as livestock and poultry manure, straw, Chinese medicine residue, kitchen waste, urban sludge, etc. under high temperature and high pressure environment, so that large molecular fiber organic matter is decomposed into small molecular polysaccharide carbon-based nutrients, while killing various bacteria and pathogens, and becoming high-quality liquid or solid organic fertilizer.

[0003] When preparing fertilizer, the solid-liquid mixture after thermal hydrolysis needs to be separated through a separation mesh plate. However, in this process, it is easy for the separation mesh plate to be blocked by solid matter, resulting in the problem of being unable to continue separation. Therefore, frequent cleaning is required. During the cleaning process, continued separation work cannot be achieved, which greatly affects the efficiency of fertilizer preparation.

[0013] The device for preparing fertilizer by treating agricultural waste by thermal hydrolysis is provided with a base, a hydrolysis box and a filter frame. After the hydrolysis box hydrolyzes the agricultural waste, the electromagnetic valve on the feed opening is opened, and the solid-liquid mixture falls into the filter screen plate in the filter frame, thereby realizing solid-liquid separation.

[0019] The rotating support mechanism includes a U-shaped vertical plate 10 fixedly connected to the upper end of the base 1, the horizontal portion of the U-shaped vertical plate 10 and the upper end of the base 1 are rotatably connected with a support column 11 through a bearing, the upper end of the support column 11 is fixedly connected to the lower end of the cross plate 5, the lower end column wall of the support column 11 is fixedly sleeved with a driven gear 12, the upper end of the base 1 is fixedly installed with a rotating motor 13, and the upper end output end of the rotating motor 13 is fixedly connected with a driving gear 14.

[0020] A cam 15 is fixedly sleeved on the column wall of the support column 11, and two side plates 16 are symmetrically fixedly installed on the upper end of the base 1. A trigger switch 17 arranged opposite to the cam 15 is fixedly installed on the upper side wall of the side plate 16. The trigger switch 17 is used to control the opening and closing of the solenoid valve on the discharge port 4.

[0021] Both ends of the transverse plate 5 are fixedly connected with an outward expansion plate 18, and the side walls of the filter frame 6 are symmetrically fixedly connected with multiple connecting studs 19. The surface of the outward expansion plate 18 is provided with multiple sleeve holes for the connecting studs 19 to extend out, and the connecting studs 19 are also threadedly sleeved with locking nuts 20.
