Description

Technical Field

[0001] The utility model belongs to the field of ore dressing and separation, and relates to a wear-resistant ore separation box switched by a hydraulic cone valve. Background Art

[0002] There may be a need for ore separation in many links of the mineral processing process. At present, ore separation boxes are usually cylindrical and rectangular. There is a large demand for ore separation in the mining field. Generally, there is a need for ore separation in the slag removal and screening link, such as high-frequency fine screens, filters, magnetic separators, etc.

[0003] For details on the cylindrical ore box structure, see Figure 1 It includes a feeding pipeline, a cylindrical ore separation box body, a discharge valve, a discharge pipeline and a screen. The cylindrical ore separation box includes an inlet box, a discharge box, a partition barrel and a discharge short circuit. A barrel is used to separate the inlet box from the discharge box, and three discharge ports are made on the barrel, corresponding to the three discharge outlets of the discharge box. The discharge box uses steel plates welded on the surface of the barrel to separate the three discharge outlets. The discharge short circuit is connected to the bottom side of the discharge outlet of the discharge box, and the discharge valves are respectively installed on the discharge short circuit and the discharge pipeline to lead the slurry to the corresponding screen. There are several problems with the use of this ore separation box:

[0004] 1. Ore separation box problem: The original design of the ore separation box is a φ3000 cylinder. The bottom lining cannot be fully laid due to its shape. During use, due to the impact of particles of different particle sizes and many edges in the slurry, wear and leakage will occur. This is a necessary link in production, and failure will cause the entire line to stop production.

[0005] 2. Difficulty in switching the screen machine when it fails: The slag removal screen is configured on site as 2 on and 1 off. The screen machine needs to be switched for daily maintenance and regular inspections. The regular inspection cycle is 15 days. It is basically impossible to switch the gate valve due to the difficulty in operation. Even the screen machine will be shut down due to the gate valve failure, which will affect the continuity of production. Through analysis, the gate valve used on site is installed on the discharge pipe. Due to the space on site, only the knife gate valve can be used, but it is greatly affected by the feed particle size. Large particles (feed particle size is 0-11mm) are easily stuck in the sealing position of the knife gate valve, and the gate plate cannot be pushed or is difficult to push, which leads to difficulty or inability to switch the screen machine when it fails.

[0006] 3. The failure rate of knife gate valve is high, and the maintenance cost and operating cost are also high: This link mainly deals with magnetic tail, the total amount of slurry is large, and the knife gate valve used is also relatively large. The gate valve needs to be replaced when it fails, and the maintenance cost is high. In addition, production needs to be stopped during maintenance, which has a great impact on production. As we all know, the operation process of the grinding and flotation process is relatively long, and it takes a long time to start and stop, and the operating cost caused by the start and stop is very high.

[0007] There are problems such as high failure rate, difficult operation, and high maintenance cost; in particular, the slag removal and screening link affects the overall operation of the grinding and flotation workshop, and once a failure occurs, it will cause a complete shutdown.

[0031] Rectangular ore separation boxes are used to separate the ore. At the same time, in order to solve the problem of the knife gate valve being affected by large particles, hydraulic cone valves and other methods are used to comprehensively transform it.

[0032] The technical solution of this application is clearly and completely described below in conjunction with the accompanying drawings.

[0033] like Figure 2 As shown, a wear-resistant ore separation box is switched using a hydraulic cone valve, an overflow plate and a box body are used to form a sand settling box, and a discharge pipe is extended upward to the inside of the sand settling box, so that ore will be stored under the sand settling box. The purpose is to grind the ore after the slurry passes through the overflow plate, thereby improving the service life of the equipment.

[0034] A wear-resistant ore separation box that is switched by a hydraulic cone valve includes a sand box with a discharge port at the bottom; a feed wear-resistant buffer box, which is formed by multiple overflow plates arranged at the bottom of the sand box, and the height of the overflow plate is lower than the height of the sand box; the discharge port is located at the periphery of the feed wear-resistant buffer box. Preferably, multiple overflow plates are located in the middle of the sand box to form a feed wear-resistant buffer box. The ore coming into the feed pipeline is fast, and a feed wear-resistant buffer box is made in the middle of the sand box for two purposes: one is to reduce the speed, and the other is to grind the ore to achieve wear resistance. The ore slurry in the sand box comes from the feed wear-resistant buffer box through the overflow plate, and the speed has been greatly reduced at this time.

[0035] An ore feeding pipeline is arranged above the ore feeding wear-resistant buffer box;

[0036] A wear-resistant cone valve, wherein the axis thereof coincides with the central axis of the discharge port; the wear-resistant cone valve can slide along the central axis and can block the discharge port during the sliding process; when the screen machine needs to be opened, the wear-resistant cone valve is driven by the hydraulic cylinder to slide upward to open the discharge port, and when the screen machine needs to be shut down for maintenance, the wear-resistant cone valve is driven by the hydraulic cylinder to slide downward to close the discharge port. The wear-resistant cone valve is driven to slide by the hydraulic cylinder. In order to ensure that the wear-resistant cone valve can be automatically controlled, the hydraulic cylinder is installed on a hydraulic cylinder fixing frame; the hydraulic cylinder fixing frame is located above the sand settling box.

[0037] In order to ensure the stability of the operation of the wear-resistant cone valve, a wear-resistant cone valve guide assembly is also included; the wear-resistant cone valve guide assembly includes

[0038] A wear-resistant cone valve guide rail parallel to the center axis of the wear-resistant cone valve;

[0039] A wear-resistant cone valve guide frame, one end of which is fixed to the hydraulic telescopic rod of the hydraulic cylinder, and the other end of which is fixed to the wear-resistant cone valve guide rail;

[0040] The wear-resistant cone valve limit control end has one end fixed on the wear-resistant cone valve guide frame and the other end sliding between the upper limit position of the peripheral device and the lower limit position of the peripheral device.

[0041] The working principle of the wear-resistant cone valve guide assembly is that when the hydraulic cylinder works, the hydraulic telescopic rod drives the wear-resistant cone valve guide frame to move, and the movement process is limited by two structures to avoid deviation. One limitation is that the wear-resistant cone valve guide rail limits the wear-resistant cone valve guide frame; the other is that the wear-resistant cone valve limit control end is driven by the wear-resistant cone valve guide rail to slide between the upper limit position and the lower limit position of the peripheral. These two limitations have both sliding position limitations and sliding direction limitations, which comprehensively realize that the wear-resistant cone valve can stably open and close the discharge pipe.

[0042] In order to ensure the service life of the ore discharge pipe, the ore discharge port is installed with a wear-resistant and detachable sleeve, and the ore discharge pipe is connected to the wear-resistant and detachable sleeve.

[0043] The discharge pipe is connected to the discharge port and can extend upward to the inside of the sand box. The function is that the port of the discharge pipe is higher than the bottom of the sand box, and a sand layer can be formed at the bottom of the sand box during use.

[0044] In order to ensure the flow rate of ore separation, a bracket is provided at the bottom of the sand settling box, and the bracket can ensure that the sand settling box is at a necessary height to achieve ore separation.

[0045] In order to ensure rapid ore separation, there are multiple ore discharge ports.

[0046] Production plan for three discharge ports:

[0047] Step 1: Use steel plates to make a rectangular / circular box, weld two overflow plates 3 at the bottom, and weld the overflow plates 3 and the side plates on both sides to form a buffer area;

[0048] Step 2: Weld wear-resistant lining plates on four sides of the buffer area to form a feed wear-resistant buffer box 2;

[0049] Step 3: Make discharge pipes 5 on both sides of the box body. The discharge pipes 5 go deep into the ore separation box to a certain height. The purpose of going deep into the certain height is to form a sand settling box 4, thereby protecting the rectangular box body;

[0050] Step 4: Make a wear-resistant detachable sleeve 6 and install it on the ore discharge pipe 5 to prevent the slurry from wearing the ore discharge pipe 5. The flange on the wear-resistant detachable sleeve 6 has two purposes: one is to fit closely with the ore discharge pipe 5, and the other is to facilitate replacement and lifting. The wear-resistant detachable sleeve 6 protects the inner wall of the ore discharge pipe, and it is installed on the ore discharge pipe. If the ore discharge pipe does not go deep into the ore separation box to a certain height, the wear-resistant detachable sleeve cannot be installed first. The most important thing is that the ore discharge pipe 5 goes deep into the sand settling box before sand can be set. The ore discharge pipe 5 has a certain height, and the bottom of the sand settling box can store materials to achieve ore grinding. At the same time, the sand settling below the sand settling box can protect the outer wall of the ore discharge pipe.

[0051] Step 5: Install the hydraulic cylinder 7, use channel steel to weld on the box to form its hydraulic cylinder fixing frame 8, and fix the cylinder flange of the hydraulic cylinder 7 on the top of the hydraulic cylinder fixing frame 8 with bolts;

[0052] Step 6: Test-install the wear-resistant cone valve 9 and the wear-resistant cone valve guide frame 10. After confirming the position of the wear-resistant cone valve guide frame slide rail 11, install the wear-resistant cone valve 9 and the wear-resistant cone valve guide frame 10 in sequence on the wear-resistant cone valve guide frame slide rail 11 inside the box body;

[0053] Step 7: Weld the wear-resistant cone valve limit control rod 12 above the wear-resistant cone valve guide frame 10, start the hydraulic oil station system 15, drive the wear-resistant cone valve 9 to open and close, confirm the positions of the lower limit 13 and the upper limit 14, and then install the lower limit 13 and the upper limit 14.

[0054] Step 8: Debug the wear-resistant cone valve 9 and the wear-resistant detachable sleeve 6 without materials. After everything is correct, debug with materials.

[0055] Further explanation on the sixth step of the wear-resistant cone valve 9, the wear-resistant cone valve guide frame 10, and the wear-resistant cone valve guide frame slide rail 11: Considering that the wear-resistant cone valve 9 is relatively long, in order to avoid it from running off due to the impact of the slurry during the opening and closing process, the present application adds a wear-resistant cone valve guide frame 10 and a wear-resistant cone valve guide frame slide rail 11, and one end of the wear-resistant cone valve guide frame 10 is a flange structure, the purpose of which is to be installed synchronously with the flange in the wear-resistant cone valve 9 to achieve synchronous operation.

[0056] Explanation on the lower limit 13 and upper limit 14 of step 7: The purpose of installing the limit is to ensure that the hydraulic cone valve is fully closed without generating downward pressure, and fully opened without damaging other auxiliary equipment.

[0057] After this method was put into use, good results were achieved, as follows:

[0058] 1. The ore separation box is designed by ourselves. It can be designed in combination with the existing production ore feeding volume, ore feeding slurry splashing range, etc., so as to better carry out internal wear-resistant measures;

[0059] 2. The discharge pipeline uses a hydraulic cone valve for switching, which can avoid the gate valve switching problem caused by large particle materials.
