Plant nutrient granulator using piston gas jet to prevent wall-sticking

Abstract

The invention discloses a plant nutrient granulator using a piston gas jet to prevent wall-sticking. The structure includes a driving device, a charging hopper, an wall-sticking preventing granulationdevice, a discharging port, a maintenance door, and a control cabinet. The driving device is mounted on the control cabinet and is connected to the control cabinet by bonding. The charging hopper isconnected to the wall-sticking preventing granulation device by welding. According to the invention, a gas guiding chamber and a gas pressure guiding chamber which are separated by a separating platefor preventing pressure release communicate with each other through the rotation of a main wheel. Meanwhile, a heat conduction layer and a pressing element heat and pressurize gas inside the pressureguiding chamber. A clearance between a self-weight piston and a valve port slowly decreases due to the gravity action of the piston, and so the pressure speed of sprayed hot air gradually increases. Agranulation groove and the surface of nutrient balls are pre-heated to reduce the moisture and viscosity, the thrust of the sprayed gas is used to smoothly separate the nutrient balls from the granulation groove, and then the sprayed hot gas dries the surface of the dropped nutrient balls to prevent the nutrient balls from sticking to each other.

Description

technical field [0001] The invention relates to the field of plant nutrient processing, more precisely, it relates to a plant nutrient granulator which uses piston air to spray the anti-sticking wall. Background technique [0002] The growth of garden plants requires sufficient nutrients. In addition to the photosynthesis of the leaves themselves, artificial fertilization is required to add nutrients. Fresh chicken and pig manure contain more nutrients and are mostly used as raw materials. In order to facilitate use, packaging and transportation, the nutrients are manufactured At present, most of them are processed and formed by double-roll granulator. The existing traditional technology is not comprehensive, and has the following disadvantages: [0003] Fresh chicken and pig manure contain more water after fermentation, and the nutrient mixture formed by stirring and mixing with plant ash has strong viscosity, which is easy to make the nutrient balls adhere to the grooves o...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a plant nutrient granulator that utilizes the piston air-spray anti-sticking wall to solve the problem that the fresh chicken and pig manure in the prior art contain more water after fermentation, which is different from the The nutrient mixture formed by stirring and mixing plant ash has strong viscosity, which is easy to make the nutrient balls adhere to the grooves on the surface of the granulation roller and cannot fall, or the nutrient balls are pulled by the sticky force, broken and scattered, which affects the quality of granulation , cause waste of nutrients, reduce the efficiency of granulation, and the nutrients adhere to the surface of the roller, which is easy to breed bacteria and pollute the nutrients
