4results about How to "Continuous and even feeding" patented technology

The present invention provides a structured flow filling process and filling system for the preparation of precise batching and forced homogenization of dewatered tailings. The filling system is composed of a feeding and metering subsystem, a stirring preparation subsystem, a slurry conveying and filling subsystem and an automatic control system; the feeding and metering subsystem includes a dewatered tailings feeding and metering system, a concentrated water feeding and metering system and a binder feeding and metering system. The filling process realizes advance material preparation, precise metering, forced activation cycle preparation-storage material adjustment and continuous discharge two-stage stirring. The invention can accurately control the filling material mix ratio and the mass concentration of the filling slurry, prepare high-concentration quasi-homogeneous steady-state structured flow filling slurry, and control the preparation quality of the filling slurry and the filling cost. The invention has strong adaptability to mines with uneven mining and filling, and can be used in mines where mechanical dewatered tailings and tailings pond sand are used as aggregates. It has low construction investment and short cycle, and is suitable for filling stations in mines of various sizes.

The present application relates to the technical fields of deep-sea mining, and especially relates to a deep-sea mining hydraulic conveying relay station and a hydraulic lifting mining system. The deep-sea mining hydraulic conveying relay station comprises a stock bin and a feeding pipe. The stock bin comprises an upper stock bin and a lower stock bin. The upper stock bin is provided with a fixed baffle. A sliding baffle is arranged between the upper stock bin and the lower stock bin. The sliding baffle and the fixed baffle separate the stock bin into independent injection space and settling space. The sliding baffle is in sliding connection with the stock bin and can rotate around the central axis of the stock bin, so that the injection space and the settling space are alternately changed. The feeding pipe comprises injection pipes respectively connected to the injection space and the settling space. The injection pipe connected to the injection space is in an open state. The present application can reduce the blockage and ore overflow in the stock bin, realize continuous and uniform feeding, and has low requirements for the structure pressure resistance and is environment-friendly.

The utility model discloses a seasoning crushing machine which comprises a crushing machine frame, a crushing chamber, a sealing cover, a discharging opening, a feeding opening, a crushing motor and a material guiding mechanism. The material guiding mechanism is used for feeding materials to a feeding port and comprises a material guiding rack, a material guiding hopper arranged on the material guiding rack and communicated with the feeding port and a dredging mechanism arranged in the material guiding hopper and used for dredging the material guiding hopper. A vibration motor is arranged on the outer side of the guide hopper; the dredging mechanism comprises two belt pulleys rotatably installed at the upper end of the inner side of the guide hopper, a conveying belt installed on the belt pulleys and a dredging motor arranged on the outer side of the guide hopper and in transmission connection with any belt pulley, and a plurality of dredging rake teeth evenly distributed in the length direction of the conveying belt are arranged on the conveying belt. According to the crusher with the design, the dredging mechanism is arranged in the guide hopper, so that the crusher is not easy to block, and the feeding is more uniform and continuous.
