Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of flotation machine auxiliary equipment, specifically to a device for efficiently eliminating foam in flotation concentrate. Background Technology
[0002] Flotation is a mineral processing method that selectively alters the hydrophobicity and hydrophilicity of mineral surfaces by adding reagents, or utilizes the natural floatability of minerals, causing them to selectively adhere to the froth surface and float to the surface of the slurry. Flotation plays a crucial role among various mineral processing methods and has a wide range of applications. It can process not only non-ferrous and ferrous metal minerals such as copper, cobalt, iron, and manganese, but also non-metallic minerals such as mica, feldspar, fluorite, and graphite. However, with certain frothing agents and frothers, the froth generated after the flotation concentrate is separated from the flotation separation equipment is difficult to break up for a considerable period. If it is not collected and treated in time, it can cause serious pollution and even corrosion of the operating platform. The traditional method of treatment is to flush the froth into the collection tank with large amounts of water, which undoubtedly increases workload and production costs. Therefore, it is essential to design a highly efficient froth removal device for flotation concentrates to simultaneously achieve solid-liquid separation of the defoamed slurry. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a device for efficiently eliminating froth in flotation concentrate, so as to overcome the shortcomings of the prior art.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0005] A flotation concentrate foam elimination device includes: a tank body, a neck-shaped inlet at the top of the tank body, the neck-shaped inlet being connected to the flotation machine foam collection tank via a pipe, a defoaming liquid spray pipe connected to a pump being fixed below the neck-shaped inlet inside the tank body, a multi-hole conical funnel being fixed below the defoaming liquid spray pipe inside the tank body, each nozzle of the defoaming liquid spray pipe being directly opposite the inner conical surface of the multi-hole conical funnel, and a vacuum port being opened on the inner wall of the tank body below the multi-hole conical funnel, the vacuum port being connected to a vacuum pump via a pipe.
[0006] Based on the above technical solution, the present invention can be further improved as follows.
[0007] Furthermore, the defoaming liquid spray nozzle is located at the lower edge of the neck-shaped inlet.
[0008] Furthermore, the defoaming liquid spray nozzle is a ring-shaped nozzle.
[0009] Furthermore, a drain port is opened on the inner wall of the tank below the vacuum port, and a drain valve is provided on the drain port.
[0010] Furthermore, a level gauge is installed outside the tank. The low-level port and the high-level port of the level gauge are connected to the inner cavity of the tank. Valves are installed on the low-level port and the high-level port respectively. The lower edge of the low-level port is flush with the upper edge of the drain port.
[0011] Furthermore, a sand discharge port is opened at the bottom of the tank, and a sand discharge valve is installed on the sand discharge port.
[0012] Furthermore, the bottom of the tank is conical, and the sand discharge port is located at the lowest point of the tank bottom.
[0013] Furthermore, the porous conical funnel is made of stainless steel.
[0014] Furthermore, the neck-shaped inlet has large diameter ends at the top and bottom, and narrows inward in the middle.
[0015] Furthermore, the ratio of the narrowed diameter to the tank diameter is between 0.5 and 0.75.
[0016] The beneficial effects of this utility model are:
[0017] This device integrates three different defoaming mechanisms into one unit. By using vacuum negative pressure traction, the foam concentrate scraped off by the flotation machine is promptly drawn into the inlet of the device and efficiently eliminated. Furthermore, after defoaming, solid-liquid separation of the flotation concentrate can be achieved, significantly reducing the extra workload of employees and effectively improving the overall working efficiency of the production line.

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0022] Example 1
[0023] like Figure 1As shown, a flotation concentrate foam elimination device includes: a tank 1, the top of the tank 1 is provided with a neck-shaped inlet 2, and the neck-shaped inlet 2 is connected to the flotation machine foam collection tank via a pipe;
[0024] Inside the tank body 1, below the neck-shaped inlet 2, is a defoaming liquid spray pipe 3 connected to a pump. The pump can pump the defoaming liquid into the defoaming liquid spray pipe 3.
[0025] Inside the tank 1, below the defoaming liquid spray pipe 3, a porous conical funnel 4 is fixed. The porous conical funnel 4 is preferably made of stainless steel, but other materials are not excluded. This is just an example. Each nozzle of the defoaming liquid spray pipe 3 is directly opposite the inner conical surface of the porous conical funnel 4. The defoaming liquid sprayed from each nozzle of the defoaming liquid spray pipe 3 can hit the inner conical surface of the porous conical funnel 4.
[0026] A vacuum port 110 is opened on the inner wall of the tank 1 below the porous conical funnel 4, and the vacuum port 110 is connected to a vacuum pump through a pipe.
[0027] The working principle is as follows:
[0028] Connect the neck inlet 2 to the flotation machine foam collection tank through a pipeline, close the sand discharge valve 131 and the liquid discharge valve 121, and vacuum the device under the premise of liquid seal (liquid seal can be achieved when the liquid level in tank 1 is higher than the liquid discharge port 120). Turn on the vacuum pump to vacuum tank 1.
[0029] Then open the flushing water valve at the end of the flotation machine foam collection tank. Under the impact of the water flow, the concentrate foam flotated by the flotation machine continuously gathers towards the neck inlet 2. Since the tank is under negative pressure, some of the concentrate foam will be squeezed and broken when it passes through the neck inlet 2 under the negative pressure, so as to achieve the first defoaming.
[0030] Turn on the pump that supplies the defoaming liquid. At this time, the defoaming liquid will be sprayed through the defoaming liquid nozzle 3 onto the inner conical surface of the porous conical funnel 4 to efficiently eliminate the foam trapped on the porous conical funnel 4, thereby achieving the second defoaming.
[0031] The remaining foam, under the traction of negative pressure and the impact of water flow, passes through the holes of the porous conical funnel 4. After being squeezed and cut radially by the holes, the foam can be defoamed for the third time.
[0032] At this point, the flotation concentrate powder is defoamed and deposited at the bottom of the tank, thus achieving solid-liquid separation.
[0033] Example 2
[0034] like Figure 1 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:
[0035] The defoaming liquid nozzle 3 is arranged at the lower edge of the neck-shaped inlet 2. In addition, the defoaming liquid nozzle 3 is preferably an annular nozzle.
[0036] Example 3
[0037] like Figure 1 As shown, this embodiment is a further improvement on embodiment 1 or 2, as detailed below:
[0038] A drain port 120 is provided on the tank wall below the vacuum port 110. A drain valve 121 is provided on the drain port 120. Observe the liquid level in the tank 1. When the liquid level is above the drain port 120 and rises rapidly, slowly open the drain valve 121 to achieve continuous and efficient removal of froth from the flotation concentrate. During the above operation, it is necessary to keep the liquid level in the tank 1 above the drain port 120. The purpose is to keep the area below the porous conical funnel 4 under negative pressure while vacuuming through the water seal, so that the foam generated during the flotation process can quickly pass through this defoaming device.
[0039] To facilitate liquid sealing and observation, a level gauge 5 is installed outside the tank 1, with its low-level port 510 and high-level port 520 connected to the inner cavity of the tank 1. The lower edge of the low-level port 510 is flush with the upper edge of the drain port 120. Valves 530 are installed on the low-level port 510 and the high-level port 520 respectively. By opening the valves 530 on the low-level port 510 and the high-level port 520 of the level gauge 5, the liquid level inside the tank 1 can be observed. When the liquid level is above the drain port 120 and rises rapidly, the drain valve 121 is slowly opened. When the liquid level in the level gauge 5 is stable and above the drain port 120 and no longer changes, continuous and efficient removal of froth from the flotation concentrate can be achieved.
[0040] Example 4
[0041] like Figure 1 As shown, this embodiment is a further improvement on embodiment 3, as detailed below:
[0042] The tank body 1 has a sand discharge port 130 at the bottom, and a sand discharge valve 131 is provided on the sand discharge port 130. When the concentrate powder at the bottom of the tank body 1 accumulates to a certain amount, the liquid discharge valve 121 is closed and the sand discharge valve 131 is opened to collect the concentrate powder.
[0043] Furthermore, the bottom of tank 1 is conical, and the sand discharge port 130 is located at the lowest point of the bottom of tank 1, which is conducive to the accumulation of concentrate powder and facilitates the collection of concentrate powder.
[0044] The porous conical funnel 4 is preferably made of stainless steel. Of course, other materials may be used in actual applications; this is just an example.
[0045] Example 5
[0046] like Figure 1 As shown, this embodiment is a further improvement on any one of embodiments 1 to 4, as detailed below:
[0047] The neck-shaped inlet 2 can be characterized by large diameter ends at the top and bottom, while narrowing inward in the middle, with the narrowing diameter being 0.5 to 0.75 times the diameter of the tank body.
[0048] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
