Description

Technical Field

[0001] This utility model belongs to the field of mineral processing and relates to a ore separation box for a flotation machine. Background Technology

[0002] Flotation machines are important mineral processing equipment. The function of the slurry distribution box is to uniformly and stably transport the slurry into the flotation machine, thus providing a good material distribution basis for the flotation process and indirectly affecting the flotation performance. However, traditional flotation machine distribution boxes have many problems in practical use.

[0003] Traditional flotation machines typically employ a single-box structure for the separation box. When the slurry falls from the feed pipe into the separation box, the significant impact force causes intense wear on the bottom of the box. This impact not only easily wears through the bottom of the box, leading to damage, but also causes excessively high slurry flow rates, disrupting the uniform distribution of the slurry and resulting in suboptimal separation. Furthermore, excessively high slurry flow rates can cause wear on the feed pipe, further affecting the flotation effect and significantly reducing flotation parameters, ultimately failing to achieve the desired mineral processing results.

[0004] To address these issues, a common method is to lay metal liners at the bottom of the ore distribution box to protect the base plate from impact and wear. However, this method also has significant drawbacks. Firstly, the metal liners will gradually wear down over time, requiring repair and replacement once they reach a certain wear level. The repair and replacement process for metal liners is complex, requiring substantial manpower, resources, and time, causing considerable inconvenience to equipment maintenance. Secondly, the relatively high price of metal liners increases equipment maintenance costs, placing a certain economic burden on the company's production and operations.

[0005] Therefore, how to solve the problems of large impact wear of slurry, uneven ore separation, and high maintenance and replacement costs in the traditional flotation machine's ore separation box has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] This application provides a flotation machine ore distribution box that can slow down the slurry flow rate, which is conducive to uniform ore distribution and improves the flotation effect; at the same time, it can grind ore, and the bottom plate will not be affected by the slurry impact after the modification.

[0007] To achieve the above technical objectives, the technical solution adopted in this application is as follows: a flotation machine ore separating box, including a T-shaped partition, wherein the T-shaped partition is installed in the separating box and divides the separating box into two parts: a feed box and a distribution box; the T-shaped partition includes a vertical plate perpendicular to the bottom surface of the separating box and a horizontal plate parallel to the bottom surface of the separating box and fixed to the top of the vertical plate; the length of the vertical plate is equal to the length of the separating box, and the height of the vertical plate is not greater than 1 / 2 of the height of the separating box; the length of the horizontal plate is equal to the length of the separating box.

[0008] As an improved technical solution of this application, it also includes a feed pipe, wherein the feed inlet is perpendicular to the bottom surface of the feed box.

[0009] As an improved technical solution of this application, the distance between the feed inlet and the bottom surface of the feed box is not less than 50cm and not more than 100cm.

[0010] As an improved technical solution of this application, it also includes a feeding pipe, which is installed on the bottom surface of the distributing box and arranged perpendicular to the distributing box.

[0011] As an improved technical solution of this application, the discharge port at the end of the discharge pipe is not less than 10cm and not more than 30cm above the bottom surface of the distribution box.

[0012] As an improved technical solution of this application, there are three feeding pipes, and the feeding ports of the three feeding pipes are distributed in an arc shape and are equidistant from the feeding port.

[0013] As an improved technical solution of this application, the feeding tube includes a rubber tube and an iron tube arranged coaxially, wherein the iron tube is located outside the rubber tube.

[0014] Beneficial effects

[0015] This application utilizes T-shaped baffles to divide the ore distribution box, slowing down the slurry flow rate, which is beneficial for uniform ore distribution and improves the flotation effect. At the same time, due to the obstruction of the vertical plate and the buffer of the horizontal plate, the ore can be ground after entering the ore distribution box, and the bottom plate is basically not impacted by the ore after the modification. In addition, this application optimizes the structure of the feed pipe, effectively improving the service life of the feed pipe. The vertical installation of the feed pipe also makes the feed pipe easy to maintain and shortens the maintenance time. Attached Figure Description

[0020] definition:

[0021] In the text, "mineral separation box" refers to the mineral separation box of the flotation machine.

[0022] like Figure 1-3 As shown, a flotation machine ore distribution box includes a T-shaped partition 3, which is installed in the ore distribution box and divides the ore distribution box into two parts: a feed box 4 and a distribution box 5.

[0023] The slurry falls from the feed pipe into the feed box 4. Due to the height of the T-shaped baffle 3, ore accumulates at the bottom of the feed box 4 and the distribution box 5. The T-shaped baffle 3 includes a vertical plate perpendicular to the bottom surface of the distribution box and a horizontal plate parallel to the bottom surface of the distribution box and fixed to the top of the vertical plate. The length of the vertical plate is equal to the length of the distribution box. If the baffle is too high, excessive ore accumulation will cause the distribution box to become overweight. The height of the vertical plate should not exceed 1 / 2 of the height of the distribution box. In practical applications, the height of the vertical plate is about 30cm. The length of the horizontal plate is equal to the length of the distribution box (meaning that the vertical plate is arranged along the length of the distribution box). The T-shaped baffle 3 slows down the slurry flow rate, which is beneficial for uniform ore distribution and reduces wear. When the slurry falls into the feed box 4, it will flow into the distribution box 5. The T-shaped baffle 3 reduces the slurry flow rate. The T-shaped baffle 3 has an additional horizontal plate compared to the traditional baffle (only vertical plate), which makes the effect of reducing the slurry flow rate more obvious, thereby reducing uneven ore distribution or wear caused by excessive slurry flow rate.

[0024] It also includes a feed pipe 1, the feed inlet of which is perpendicular to the bottom surface of the feed box 4. The feed inlet is at least 50cm away from the bottom surface of the feed box 4.

[0025] It also includes a discharge pipe 2, which is installed on the bottom surface of the distribution box 5 and arranged perpendicular to the distribution box 5. The discharge port at the end of the discharge pipe 2 is at least 10cm higher than the bottom surface of the distribution box 5. The discharge port is higher than the bottom plate of the distribution box 5, so that the bottom of the distribution box 5 can accumulate ore to prevent wear on the bottom plate. The T-shaped partition 3 allows the distribution box 5 to accumulate ore, but if the discharge port is not raised, the ore will flow out from the discharge port, so raising the discharge port is also to allow the distribution box 5 to accumulate a small amount of ore.

[0026] As an improved technical solution of this application, there are three feeding pipes 2, and the feeding ports of the three feeding pipes 2 are distributed in an arc shape and are equidistant from the feeding port. The arc-shaped distribution of the three feeding ports and their equal distance from the feeding port are beneficial for uniform ore distribution. Figure 3 As shown, the discharge port is the upper pipe opening (top pipe opening) of the discharge pipe 2. The point where the slurry falls from the feed port to the feed box 4 is called the discharge point. The discharge point is equidistant from the three discharge ports. Because the discharge ports are distributed in an arc shape, and the center of the circle is at the discharge point, the discharge point is equidistant from the three discharge ports. Equal distances are conducive to uniform ore distribution.

[0027] As an improved technical solution of this application, the feeding pipe 2 includes a rubber pipe and an iron pipe coaxially arranged, wherein the iron pipe is located outside the rubber pipe. A wear-resistant rubber sleeve is provided in the feeding pipe 2; when worn, it can be pulled out and a new one inserted, significantly reducing maintenance time.

[0028] Application examples

[0029] A flotation machine ore separating box, the device includes a separating box, a feed pipe 1, a discharge pipe 2, and a T-shaped partition 3. The T-shaped partition 3 is installed inside the separating box, dividing the separating box into two parts: a feed box 4 and a distributing box 5; the discharge pipe 2 is equipped with a wear-resistant rubber sleeve to protect the discharge pipe 2.

[0030] The ore distribution box measures 2.2m x 2m x 1m, with a T-shaped partition 3 in the middle. The T-shaped partition 3 is 30cm high, 20cm wide, and 2.2m long.

[0031] Among them, the feed pipe 1 has a diameter of 20cm, is placed vertically, and is 80cm away from the bottom plate of the feed box 4.

[0032] There are 3 feed pipes 2. The feed pipe 2 consists of two layers: an outer iron pipe and an inner wear-resistant rubber pipe. The inner diameter of the iron pipe is 24cm, and the inner diameter of the wear-resistant rubber sleeve is 20cm, the outer diameter is 24cm, and the thickness is 1.5cm, which facilitates maintenance and replacement. The feed pipe extends upward to 20cm above the bottom of the distribution box 5, so that the distribution box 5 can accumulate ore and reduce the wear of the bottom plate.

[0033] The feed pipe 1 is centered on the left and right sides, but is 30cm away from the front plate of the ore distribution box (the front plate of the ore distribution box is one side of the feed box relative to the vertical plate). The three discharge ports are distributed in an arc shape with the material points as the center, and the distance from the feed port is equal, all being 1.5m, so that the ore distribution is more uniform.
