3results about How to "Eliminate concentration differences" patented technology

The application discloses an electrolytic cell testing device. The electrolytic cell testing device comprises a cathode pipeline, an anode pipeline and a mixing pipeline. The cathode pipeline can be connected with a cathode chamber of an electrolytic cell to form a cathode circulation loop. The anode pipeline can be connected with an anode chamber of the electrolytic cell to form an anode circulation loop. The mixing pipeline comprises a mixing tank, a first branch and a second branch. The mixing tank is connected in parallel with the cathode circulation loop through the first branch and can be connected with or cut off from the cathode circulation loop. The mixing tank is also connected in parallel with the anode circulation loop through the second branch and can be connected with or cut off from the anode circulation loop. The electrolytic cell testing device can expand the performance testing conditions of the electrolytic cell.

This invention discloses a liquid manure spraying system suitable for various land conditions, comprising a flexible traction mechanism and a self-balancing application device. The flexible traction mechanism includes a traction motor, a control coil driven by the traction motor, and a flexible traction rope mounted on the control coil. The self-balancing application device includes a chassis, a spraying rod, and a rubber-plug nozzle. The chassis has a rubber tire structure and is connected to the flexible traction rope. During spraying, the flexible traction rope pulls the chassis upwards at an angle. A shock-absorbing structure is installed inside the chassis. The spraying rod includes a fixed rod and a telescopic rod. The fixed rod is fixedly mounted on the chassis and connected to a storage tank via a liquid inlet pipe. The lower end of the telescopic rod cooperates with the fixed rod, and the upper end is equipped with a rubber-plug nozzle. This invention can solve the problems of pipe blockage, uneven spraying, poor spraying effect, and intelligent farmland fertilization in existing equipment, promoting the development of agricultural fertilization towards a more intelligent, convenient, and precise direction.

The application relates to the technical field of fertilizer production, in particular to a selenium-containing water-soluble fertilizer production device. The device comprises a treatment tank, a rotating shaft is rotatably arranged in the treatment tank, the rotating shaft is driven to rotate by an external driving device, a plurality of driving discs are arranged on the rotating shaft in an axial direction, a plurality of radial rails are arranged on the outer edge surface of each driving disc, stirring blades are slidably arranged on the rails, elastic members I are arranged between the stirring blades and the rails, a guide plate is arranged on one end of the stirring blades facing the rotating shaft, a ring rail corresponding to each driving disc is arranged on the inner wall of the treatment tank, one end of the stirring blades away from the rotating shaft abuts against the inner wall of the ring rail, and a plurality of arc-shaped convex blocks are arranged on the inner wall of the ring rail. The stirring blades are designed to be separated from the rotating shaft, the stirring blades can move in the radial direction while synchronously rotating with the rotating shaft, the radial material pushing of the guide plate is realized while realizing horizontal layer material shearing diffusion stirring, material convection between the inside and outside of the horizontal layer is realized, and the horizontal layer concentration difference is eliminated.
