The invention relates to a crushing, screening and washing process of high-mud and high-water surface mixed hematite. The crushing, screening and washing process comprises the steps of performing three crushing processes including coarse crushing, intermediate crushing and fine crushing on mixed hematite of which the iron grade is 30% to 35%, the slime content is 20% to 40% and the granularity is0 to 750 mm in a raw ore stock bin, wherein in the coarse crushing process, a roller type screening machine and a double-geared roller crusher are adopted to screen to deslime and crush, and then a rotary drum washer and a drum screen are adopted to wash to deslime and perform dry and wet separation; in the intermediate crushing process, an intermediate crushing cone crusher and a dry double-layervibrating screen closed loop are adopted to treat oversize products of the drum screen, and undersize products of the drum screen are treated by a two-stage wet single-layer vibrating screen, a cyclone unit and a dewatering screen so as to obtain selected pulp; and in the fine crushing process, a fine cone crusher and a linear vibrating screen are adopted to obtain feed raw materials. According to the crushing, screening and washing process, the problems of adhesion and blockage of minerals are effectively solved, and the energy consumption is greatly reduced.

The invention relates to a method for turning off a secondary absorption concentrated acid pump without stopping production, and belongs to the technical field of smelting flue gas acid making. By adjusting the production load of the smelting furnace and increasing the pre-conversion absorption and the primary conversion absorption production load, a standby pump is turned off when the secondary conversion absorption does not bear the production load, continuous and stable operation of a production organization is ensured, the production load of the smelting furnace can be gradually recovered when the standby pump normally operates, the operation rate of a production system is ensured, equipment idling and system temperature rise electric energy consumption are completely prevented, and the relevant standard requirements of clean production, energy conservation and consumption reduction are met.

The invention discloses a device and method for an anti-tipping clamping groove type traction thickener. The device comprises two access channels, a supporting structure and a moving mechanism , wherein the two access channels are arranged below the thickener, are positioned on the same axis and are respectively positioned on two sides of a central column; the supporting structure is used for supporting the thickener and comprises a plurality of pairs of upright posts arranged at equal intervals along the access channels, and each pair of upright posts is respectively positioned on two sides of the access channels; the tops of the upright posts are fixed with the bottom of a pool body, and a cross beam is fixedly connected between each pair of upright posts; the moving mechanism completes movement of the thickener through the supporting structure and comprises two carrier vehicles and a plurality of clamping grooves which are formed in vehicle plates of the carrier vehicles through lifting structures and used for clamping the cross beams; and each clamping groove is formed in the width direction of the vehicle plates. The device is simple in structure and convenient to move, rapid movement of the thickener can be achieved, construction of a full-modular movable separation plant of an open-air iron-rich mine is promoted, the raw ore transportation cost and the road construction cost are reduced, and repeated utilization of ore separation facilities is achieved.

The invention provides a rail-mounted mobile thickener, which comprises a thickener body erected on the ground through steel supporting columns, wherein paired steel columns are arranged on the lower portion of the pool body of the thickener body along one diameter of the pool body at equal intervals, the paired steel columns are symmetrical about the diameter, a rotating shaft is connected between the lower portions of the two steel columns of each pair of steel columns, wheels are connected to the two ends of each rotating shaft, a rectangular rail foundation pit is dug in the ground below the pool body, a sinking rail is arranged in the rail foundation pit, the wheels are arranged on the sinking rail, a traction locomotive is connected to the paired steel columns at the edge of the pool body, an earth surface track is arranged between the sinking track and a moving destination, and the traction locomotive travels on the earth surface track. According to the invention, the difficulty in moving the thickener with small and medium diameters is solved.

The invention discloses a rotary RTO rotating valve and a heat storage type organic waste gas incineration furnace. The rotary RTO rotating valve comprises a stator, a rotor and an air separation area; an inner cylinder of the stator and an inner cylinder of the rotor are connected through an inner cylinder seal soft connecting module; and an outer cylinder of the stator and an outer cylinder of the rotor are connected through an outer cylinder seal soft connecting module.
