Description

Technical Field

[0001] This utility model relates to the field of mining machinery and equipment, specifically to a device for upgrading ilmenite. Background Technology

[0002] Ilmenite, an oxide mineral of iron and titanium, also known as titanomagnetite, is the main ore for titanium refining and is associated with enstatite, plagioclase, and other minerals. In existing ilmenite beneficiation processes, spiral sluices are frequently used. A slurry feed pipe is typically installed above the spiral sluice. To improve the beneficiation effect and efficiency, an additional water supply pipe is usually added to replenish the slurry. This water supply reduces the slurry density, preventing mineral particle stratification difficulties due to excessive concentration, and also reduces slurry viscosity, facilitating particle dispersion within the spiral sluice and improving beneficiation accuracy. Furthermore, a cutter at the bottom of the spiral sluice further enhances beneficiation accuracy by intercepting the concentrate and tailings. However, the slurry and water supplied by the existing feed and water supply pipes above the spiral sluice are not adequately mixed, resulting in uneven slurry distribution and affecting beneficiation performance. Additionally, the position of the existing cutter is difficult to adjust, leading to a higher impurity content in the beneficiated concentrate and lower concentrate quality. Therefore, there is an urgent need for equipment that can improve the quality of ilmenite sorting. Utility Model Content

Detailed Implementation

[0016] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0017] Example 1: Reference Figures 1 to 5 This utility model provides an ilmenite upgrading device, including a mounting frame and a spiral chute, a uniform feed cylinder, and a mixing cylinder mounted on the mounting frame. The uniform feed cylinder is located above the spiral chute and is connected to several feed pipes that supply material to the spiral chute. The mixing cylinder is located above the uniform feed cylinder, with a feed pipe and a water inlet pipe connected to one end of the mixing cylinder, and a discharge pipe for supplying material to the uniform feed cylinder connected to the other end of the mixing cylinder. A mixing mechanism is provided on the mixing cylinder. A ore cutter is detachably mounted on the spiral chute, and an adjustment mechanism for adjusting the angle and position of the ore cutter is provided on the spiral chute.

[0018] The raw ore slurry is supplied with water through the feed pipe and water inlet pipe, respectively. The mixing mechanism in conjunction with the feed pipe and water in the mixing cylinder is used to stir the raw ore slurry and water evenly to obtain a uniform slurry. This uniform slurry flows to the uniform distribution cylinder through the discharge pipe. The uniform distribution cylinder is then evenly distributed to the spiral chute by several feed pipes for mineral processing. This effectively reduces the problem of poor separation effect caused by uneven slurry mixing, which is conducive to improving the mineral separation quality. The angle and position of the cutter can be adjusted as needed to achieve separation of different slurry concentrations, which helps to further improve the quality of ilmenite obtained after slurry separation.

[0019] Specifically, the cutter consists of an outer side plate, an inner side plate, and a connecting block. One end of the inner side plate is connected to one end of the outer side plate to form a pointed structure, and the other end of the inner side plate is open to the other end of the outer side plate. The connecting block is used to connect the inner side plate and the outer side plate.

[0020] The pointed structure formed by the outer and inner side plates can be used to divert the slurry flowing to the tail end of the spiral chute, and guide the diverted slurry along the inner and outer side plates to separate the concentrate and tailings.

[0021] Specifically, the connecting block is provided with a connecting cylinder, and the spiral chute is provided with a circular hole for the connecting cylinder to be inserted.

[0022] The connecting cylinder and the round hole are connected by a plug-in joint. After the connecting cylinder is inserted into the round hole, it can rotate relative to the round hole. By rotating it to the designated position and cooperating with the adjustment mechanism, the angle of the cutter can be adjusted.

[0023] Example 2: Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 In conjunction with the technical solution of Embodiment 1, in this embodiment, the adjusting mechanism includes a screw and a threaded sleeve. The connecting block is provided with an installation groove for the threaded sleeve to be inserted into. The bottom of the threaded sleeve abuts against the bottom of the installation groove. The connecting cylinder and the connecting block are provided with through holes for the screw to pass through. The through holes through which the screw passes are threadedly connected to the threaded sleeve. The end of the screw is provided with a handle. The diameter of the handle is larger than the diameter of the circular hole. The upper end of the handle abuts against the bottom of the spiral chute.

[0024] When it is necessary to adjust the angle of the cutter, loosen the handle to release the fastening of the cutter. Then, the cutter can be rotated to adjust the angle. After the cutter is rotated to the designated position, tighten the handle again. The upper end of the handle is pressed against the bottom of the spiral chute, and the bottom of the threaded sleeve is pressed against the top of the mounting groove, thereby connecting the connecting block and fixing the entire cutter to the spiral chute, realizing the angle adjustment of the spiral chute.

[0025] Specifically, the threaded sleeve is in the shape of a square column, and the mounting groove is in the shape of a square groove and is used to restrict the rotation of the threaded sleeve.

[0026] A square-shaped threaded sleeve is inserted into a square-grooved mounting slot. The mounting slot limits the rotation of the threaded sleeve, preventing it from rotating relative to the slot. When installing or adjusting the cutter, first insert the threaded sleeve into the mounting slot, pass the screw through the through hole, and turn the handle. The screw connects to the threaded sleeve. Using the mounting slot's rotation-limiting effect, hold the cutter in place to maintain the insertion of the threaded sleeve and prevent accidental rotation. Then, turn the handle to secure the cutter. No additional securing of the threaded sleeve is required, facilitating angle adjustments.

[0027] Specifically, the threaded sleeve is provided with an elastic spring wire in an L-shaped structure. A slot is provided at the upper end of the connection between the inner side plate and the outer side plate. The end of the spring wire is inserted into the slot and abuts against the bottom of the slot. The spring wire is used to press the connection between the inner side plate and the outer side plate against the spiral chute.

[0028] The spring wire is made of rust-resistant stainless steel spring material such as 304, 316 or 316L.

[0029] Using an L-shaped spring wire structure, when the cutter is fixed to the spiral chute by a screw handle and threaded sleeve, the threaded sleeve moves into the mounting slot as a whole. One end of the spring wire moves downward with the threaded sleeve, while the other end of the spring wire is limited by the bottom of the slot and cannot move further down. At this time, the spring wire deforms, and the other end of the spring wire abuts against the bottom of the slot, and the pointed structure formed by the inner and outer side plates abuts against the spiral chute, ensuring that the tip of the cutter fits against the spiral chute, which plays a certain role in preventing ore from escaping.

[0030] Specifically, the length of the connecting cylinder is less than the depth of the circular hole.

[0031] Setting the length of the connecting cylinder to be less than the depth of the hole effectively prevents the handle from directly contacting the connecting cylinder during the tightening process. This also prevents friction between the handle and the connecting cylinder from accidentally causing the connecting cylinder to rotate, reducing the force applied by the operator when holding the cutter during tightening and facilitating the tightening and adjustment of the cutter.

[0032] Example 3: Reference Figure 1 and Figure 2 In conjunction with the technical solutions of Embodiments 1 and 2, in this embodiment, the mixing mechanism includes a servo motor and a rotating rod. The rotating rod is rotatably mounted on the mixing cylinder, and a spiral blade is provided on the rotating rod. The servo motor is connected to the rotating rod and drives the rotating rod to rotate.

[0033] The servo motor is used in conjunction with a control box equipped with a PLC control panel to control its speed.

[0034] After the raw ore slurry and clean water are fed into the mixing cylinder through the feed pipe and water inlet pipe respectively, the servo motor drives the spiral blades to rotate, mixing and stirring the raw ore slurry and clean water. The uniformly mixed ore slurry is then guided to the discharge pipe. The uniformly mixed ore slurry is evenly distributed to various locations above the spiral chute through several feed pipes on the equalizing cylinder for mineral beneficiation. This effectively reduces the problem of poor separation effect caused by uneven mixing of ore slurry, and helps to improve the quality of mineral separation.

[0035] Specifically, valves are installed on both the feed pipe and the water inlet pipe.

[0036] The feed rates of raw ore slurry and clean water at the feed pipe and water inlet pipe can be adjusted by valves, facilitating slurry mixing.

[0037] The valves can be solenoid valves controlled by a control box with a PLC control panel. Flow meters can be installed at the feed pipe and water inlet pipe to monitor the flow rate. The flow meters can be V131 or CK-LDE models. The flow information detected by the flow meters is displayed on the PLC control panel, and the opening size of the solenoid valves at the feed pipe and water inlet pipe is controlled, thereby realizing the control of the feed rate of raw ore slurry and the feed rate of clean water.

[0038] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
