This invention relates to the field of agricultural machinery technology and discloses a mechanism for adjusting the speed of a star wheel. The mechanism includes a steel frame with star wheel shafts evenly distributed from bottom to top. Star wheel bodies are evenly fitted onto the star wheel shafts along their axial direction. Sprockets and chains are provided between adjacent star wheel shafts. A hydraulic motor is mounted on the outside of the steel frame. The mechanism also includes a centrifugal wheel, with its main body fixed to one end of the star wheel shaft. A radial groove is formed on the centrifugal wheel, and a centrifugal counterweight and a cam are connected within the groove via a first serpentine spring. The main body is connected to one end of the star wheel shaft via a bearing, and a first torsion spring is provided between its outer wall and the star wheel shaft. A connecting arm is provided between the cam and the centrifugal counterweight. The mechanism utilizes a hydraulic motor to independently drive the star wheel, achieving stepless speed regulation. Through the triple synergistic effect of centrifugal force adaptive clamping force adjustment, automatic jamming clearance, and eccentric linkage vibration unblocking, it effectively prevents the star wheel body from jamming and corn kernel damage, resulting in a high peeling rate, low kernel loss rate, and stable operation.

The invention belongs to the technical field of recovery of valuable metal from iron-cobalt alloy and production of metal cobalt, and particularly relates to a method for producing metal cobalt from waste iron-cobalt alloy, which comprises the following steps: (1) atomizing to prepare powder; (2) oxidizing and leaching; (3) extracting iron; (4) reverse extraction of iron; and (5) cobalt recovery. According to the method, step-by-step extraction and separation of iron and cobalt can be achieved only through one extracting agent, excessive iron carbonate is added during reverse extraction of iron, the obtained ammonia soap P507 can be directly used for next-step cobalt extraction, the process is simple and convenient, operation is easy, and the using amount of the extracting agent is small; according to the method, the ammonium carbonate solid is adopted as the iron stripping agent, the stripping rate of iron is high, and the hydrolysis reaction of iron carbonate and water can be inhibited, so that iron hydroxide colloid is not generated, and the subsequent cobalt extraction effect of the ammonia soap P507 is not influenced.

The invention discloses a rapid extraction and detection method for phosphorus form in water, and particularly relates to the field of analytical chemistry. The method comprises the steps of preparation of a solid-phase extraction column, solid-phase extraction of water-soluble phosphorus, back extraction and purification of extract liquor. The solid-phase extraction column filler disclosed by the invention adopts the lanthanum-zirconium-aluminum-based composite adsorbent, so that the solid-phase extraction column filler is large in adsorption capacity and high in rate, and has a relatively good adsorption effect on inorganic phosphorus and organic phosphorus; an iron-manganese-based adsorbent is not used as a solid-phase extraction column filler, so that the influence of paramagnetic substances such as iron and manganese in an extraction solution on nuclear magnetic resonance is greatly reduced, and the resolution ratio is improved; compared with a method for freeze-drying a large-volume water sample, the solid-phase extraction method for determining the form of the water-soluble phosphorus has the advantages of simplicity, convenience and large-scale determination.

The present invention uses ReO 4 ‑ and / or 99 T8h 4 ‑ The amide extractant with unique extraction effect is used for liquid phase extraction, with high extraction and stripping rates, which can achieve ReO 4 ‑ and / or 99 T8h 4 ‑ This type of extractant has good selectivity under high acid conditions. For example, D2EHAG extractant is different from previous extractants in that it can 3 ‑ with ReO 4 ‑ The selectivity of D2EHAG to ReO 4 ‑ The removal rate is still close to 70%, and the extraction effect is very good). This type of extractant has a good extraction effect under high acid conditions (when the acid concentration is 1-6 mol / L), among which PELLAG extractant has the best extraction effect under high acid conditions of 1 mol / L. This type of extractant can directly separate ReO with an alkaline stripping agent in one step. 4 ‑ and / or 99 T8h 4 ‑ The process is simple, requires few equipments and is suitable for industrial use.
