Description

Technical Field

[0001] The utility model relates to the technical field of mineral mining equipment, in particular to a closely arranged nozzle structure device for ore dressing. Background Art

[0002] After the intelligent transformation, modern ore dressing equipment has the function of ore visual intelligent identification and screening. After the ore is selected and identified, the ore falling trajectory can usually be jetted through an air or water jet array to make the ore fall into the corresponding collection device to complete the ore sorting. The following materials are retrieved for ore jet sorting devices in the prior art:

[0003] Intelligent mineral sorting system and method; 202110058852.6; The present invention is based on online coal quality detection technology, visual recognition, and positioning technology to detect the properties and positions of minerals, and uses water jets to sort minerals according to the category of minerals. The fine process of the present invention for identifying each individual material and sorting them one by one is particularly suitable for sorting materials into multiple categories of products, greatly improving the accuracy of sorting. The sorting execution system of the present invention uses water jet technology. Compared with the existing dry sorting and blowing technology, the energy carried by the water jet is greater and more concentrated, and large pieces of materials that are difficult to sort with the existing technology can be sorted; the time used for water jet shooting at the target material is shorter and more efficient than that of dry sorting and blowing technology; the current dry sorting technology uses high-pressure gas to blow materials, which causes the airflow to interfere with the running trajectory of non-target materials, and even the defects of inaccurate blowing, thereby improving the sorting accuracy; there is no coal dust caused by the existing dry sorting technology blowing materials, and no supporting dust removal equipment is required.

[0004] A high-pressure air jet type ore separation device; 202310406336.7; A high-pressure air jet type ore separation device, comprising a rotating rod, the outer surface of the rotating rod is symmetrically fixedly connected with two groups of brackets, a movable net bag is hingedly connected between one group of brackets, the outer surface of the rotating rod is symmetrically fixedly connected with two fixed net bags, and the two ends of the rotating rod are provided with positioning mechanisms for limiting its unidirectional rotation. The advantage of the present invention is that by setting a material receiving mechanism and a positioning mechanism, the jet force of the jet assembly can be reduced during use, so that some large ores fall on the movable net bag close to the first outlet side, and then some small ores fall on another movable net bag, and then the ore can be buffered by the first net bag. When the weight of the accumulated small ores is greater than the weight of the accumulated large ores, the rotating rod will be prompted to rotate, so that the screened large ores and small ores can be discharged through the second outlet.

[0005] However, the jet ore sorting device in the prior art has a nozzle density that is not dense enough, resulting in the trajectory of the jet-controlled ore falling being not precise enough. Summary of the invention

[0006] The utility model aims to provide a closely arranged nozzle structure for mineral processing, which is installed at the conveyor belt terminal of intelligent mineral processing equipment and cooperates with a visual intelligent mineral processing system to utilize closely arranged nozzles to spray and classify the falling ore, and enter the material distribution funnel for accurate classification and transmission.

[0007] In order to achieve the above object, the technical solution of the utility model is as follows:

[0008] A closely arranged nozzle structure for mineral processing, the nozzle is installed at the end of a conveyor belt, horizontal injection ports are evenly distributed on the front of the nozzle, a plurality of planes with different inclined directions are arranged on the back of the nozzle, a plurality of air inlets are arranged on each plane, and each air inlet is connected to a injection port channel.

[0009] The nozzles are coordinated with the visual intelligent mineral processing equipment system. When each ore reaches the end of the conveyor belt, the nozzle corresponding to the position of the ore sprays the fluid to intervene in the trajectory of the ore falling, so that it falls to the designated collection frame to achieve the purpose of mineral processing and screening. Since the nozzles are arranged closely, the diameter is only 3mm, the hole spacing is 6mm, but the diameter of the air inlet and the air inlet pipe is 8mm, the air inlet is alternately arranged on each plane on the back, so that the nozzle opening can be closely arranged.

[0010] The nozzle is installed above or below the end of the conveyor belt. When the nozzle is installed below the conveyor belt, the ore to be separated is blown forward or upward to enter the dividing frame far away from the conveyor belt, and the unsorted ore falls freely into the dividing frame close to the conveyor belt; when the nozzle is installed above the conveyor belt, the ore to be separated is blown downward to enter the dividing frame close to the conveyor belt, and the unsorted ore falls freely to enter the dividing frame far away from the conveyor belt.

[0011] The threaded rods at both ends of the nozzles pass through the long holes on the pillars and are anchored with nuts to achieve horizontal fixation of the nozzle array.

[0012] The two ends of the nozzle are also connected to the lower end of the vertical screw rod, and the upper end of the screw rod passes through the through hole of the horizontal plate at the upper end of the column and the thread hole of the nut. The screw rod suspends the two ends of the nozzle array, and the vertical displacement adjustment of the nozzle array is achieved by screwing the nut and moving the screw rod vertically.

[0013] A material dividing funnel is arranged below the end of the conveyor belt, and a material dividing plate is arranged in the middle of the material dividing funnel to divide the funnel into two parts, and the lower end of each part of the funnel is connected to a different discharging belt. Different material discharging parts of the funnel correspond to different discharging belts, and the ends of different discharging belts correspond to qualified ore collection boxes or waste boxes.

[0014] The bottom of the distribution plate is hinged to the side wall of the distribution funnel, an arc guide groove is arranged in the middle of the side wall of the distribution funnel, matching bolts are arranged on both sides of the middle of the distribution plate to pass through the guide groove, and the distribution plate is fixed at an angle by butterfly nuts. When the overall density of the ore changes, the position of the ore falling can be made more accurate by adjusting the inclination angle of the distribution plate. There is no need to change the air intake of the injection array.

[0015] A plurality of electromagnetic valves are arranged below the conveyor belt, and the electromagnetic valves are matched with each air inlet in the nozzle in a one-to-one correspondence, and the electromagnetic valves are installed on the electromagnetic valve bracket.

[0016] Advantages of utility models
