Definitions

  • the invention relates to a method and a device for X-ray controlled raw material separation and can be used for the preparation of mineral raw materials, secondary metal raw materials etc.
  • a method for X-ray controlled cutting of usable minerals (SU, A, 952384) is known, according to which pieces of a raw material to be separated are passed in front of an X-ray source, the fluorescent X-ray radiation and the X-ray radiation scattered by a piece are measured simultaneously, the intensity ratio of the fluorescent X-ray radiation to the determining usable component and the scattered radiation of each piece is determined and can be separated according to the value of the said ratio by comparing it with a predetermined threshold value.
  • the intensity of the scattered radiation is recorded in an energetic range that corresponds to a photo tip of this radiation.
  • the method is carried out by a device (SU, A, 952384) which contains an isotope housed in a collimator and X-ray detectors which are designed as proportional counter tubes and are arranged on both sides of the isotope. Pieces of the raw material to be separated are passed in front of the isotope and in front of the counter tubes in free fall.
  • a device SU, A, 952384
  • a disadvantage of this method or this device is that pieces of raw material pass the isotope and the detectors along different drop curves, therefore one has to arrange these elements and adjusting mechanisms with the help of which pieces of raw material are separated at a sufficient distance from the mean movement path of the pieces so that the latter do not touch any of these elements. This leads to the increased performance of the adjusting mechanisms, which reduces the economics of the method, as well to reduce sensitivity when recording the secondary radiation.
  • the sensitivity of the recording of the secondary X-ray radiation is also reduced by the fact that pieces of raw material that pass the isotope and the proportional counter tubes in free fall are randomly oriented towards them, i.e. they can face both wide and narrow edges. Since the pieces are only exposed to X-rays for a very short time, this arbitrary orientation of the pieces with respect to their direction of movement can cause a piece whose content of useful components exceeds a threshold value to face the isotope with a narrow edge is judged to be inferior and ends up in waste. All of this lowers the effectiveness of a divorce.
  • a method for X-ray-controlled raw material separation is also known, which is described in the scientific and technical information collection "Obogaschenie rud" No. 3 (178), 1985 (Leningrad), A, P.Chernov and others. "Rudosortirowochnyi avtomat dlya pokuskovogo obogaschenia mineralnogo syrya", p.31 to 33) described facility is carried out.
  • the method consists in arranging the pieces of the raw material to be separated on a conveying surface in a monolayer in a stable position, as a result of which these pieces move progressively on the transport surface in stabilized paths without tipping over or separating from this surface.
  • pieces are irradiated by X-ray radiation, the secondary X-ray radiation that passes through the pieces is measured and high-quality pieces are picked out according to an intensity value of the secondary radiation.
  • the device contains the sequentially arranged along the direction of movement of a raw material: a loading bunker, a transport device consisting of a weakly inclined high-speed feeder and a belt conveyor, as well as pneumatic actuating mechanisms.
  • a stabilizer arranged in the form of a brush conveyor, which presses the pieces against the belt and brings them into a stable position.
  • X-ray radiation sources distributed uniformly over the entire bandwidth and coaxially with them above the belt are arranged under the conveyor belt in the direction of movement of raw material.
  • the latter also function as a coordinate system by determining the dimensions of the pieces and their position on the belt.
  • There is also a computer the inputs of which are connected to the outputs of the detectors and the outputs of which are connected to adjusting mechanisms.
  • the x-ray radiation sources and detectors form individual viewing zones over the width of the moving raw material flow, and adjusting mechanisms are arranged in each of the said viewing zones at discharge sections from the conveyor belt.
  • the chute bottom of the high-speed vibratory feeder has a stepped acceleration profile, which increases the speed of movement of the raw material pieces, the height of the flow of the raw material decreases accordingly, and pieces move in a monolayer at the feeder exit.
  • raw material pieces are pressed against the belt surface by means of stabilizer brushes and then set on edges, which ensure a stable position of pieces during the movement.
  • detectors When pieces of raw material pass by X-ray sources, detectors record the intensity of the secondary radiation that has passed through the pieces, the computer processes detector signals which are proportional to the content of the pieces of usable components and issues commands to switch on the corresponding actuating mechanisms for picking up the usable pieces. A number of the actuating mechanisms that are switched on correspond to the dimensions of the pieces to be harvested.
  • pieces are arranged on the conveyor in the stable position, they face the X-ray sources with an edge, although it does not have a maximum area, but are sufficiently large, thereby eliminating measurement errors inherent in the method and the device according to SU, A, 952384 are. Nevertheless, the above-described method and device do not have a high effectiveness in cutting, since detectors record X-rays that have passed through pieces and this radiation has only a weak dependence on the concentration of usable components in pieces. With regard to the concentration of usable components in a raw material, their secondary fluorescence X-ray radiation is more meaningful.
  • the invention has for its object to develop a method for X-ray controlled raw material separation and to create a corresponding device with the help of which a secondary fluorescent X-ray radiation of the raw material pieces can be measured without interference from background radiation, the pieces being passed through in front of X-ray radiation sources and detectors and before Setting mechanisms, with the help of which usable pieces are harvested, are guaranteed in stabilized paths, which increases effectiveness of the divorce and the energy expenditure for the work of the adjusting mechanisms are reduced.
  • This object is achieved in a method for X-ray-controlled raw material cutting, which consists in placing pieces of a raw material to be separated on a transport surface in a monolayer, arranging them in a stable position, determining the dimensions of the pieces and their position over the width of the monolayer, and irradiating the pieces by X-radiation are, the secondary X-ray radiation is measured from each piece and the usable pieces are extracted based on the measurement results, solved according to the invention in that the pieces are conveyed in a monolayer while maintaining their position in relation to the direction of movement without support, and the Determination of the dimensions of pieces and their position over the monolayer width, the irradiation by X-rays, the measurement of the secondary radiation and the harvesting of usable pieces in the course of said further transport of the pieces without support be carried out.

  • the effectiveness of the separation is increased in the method according to the invention and the corresponding device in that the secondary fluorescent X-ray radiation of usable components in pieces and a scattered radiation of pieces without interference from background radiation can be registered with a movement of the raw material without support, as in the method according to SU, A, 952384 .

With further movement of the pieces on the transport surface, each of them is in a stable position, i.e. on such an edge that it continues to support this edge (even if only in three points) without rolling while constantly resting this edge.

This increases the sensitivity of the measurements, as a result of which raw materials with a usable component content can be separated down to 0.5% and reduces the energy expenditure for valve work.
  • compressed air valves can be arranged at a distance of 1 to 2 cm from pieces, while in the known method when the pieces are unstabilized in the arrangement area of the compressed air valves, this distance must be at least 5 to 8 cm. Accordingly, an air throughput for compressed air valves in the method according to the invention is reduced by 15 to 20 times because the impact force of an air jet decreases inversely proportional to the square of the distance between a valve and a piece of raw material.
  • the invention is intended for the preparation and sorting of raw material pieces in a large range of 15 to 200 mm, in which usable components with an atomic number of not more than 20 are contained.
