Description

Technical Field

[0001] The utility model relates to the technical field of slurry distribution, in particular to a slurry flow distributor used for connecting a cyclone and a large magnetic separator. Background Art

[0002] Slurry spreading refers to the process of evenly distributing slurry on the equipment of the next process through specific equipment and methods during mineral processing or related industrial processes to ensure processing efficiency and product quality. Slurry spreading technology is widely used in wet mineral processing operations, coal, steel, chemical and other industries, and plays an important role in improving production efficiency and product quality. Reasonable spreading technology can not only improve production efficiency, but also reduce environmental pollution, such as reducing dust and wastewater emissions.

[0003] In existing mineral processing plants, when slurry is beneficiated, the slurry passes through a cyclone and then a large magnetic separator for beneficiation. The cyclone and the large magnetic separator are mostly connected by wear-resistant pipes. Since the pipeline transports slurry, the discharge pressure of the cyclone is relatively high, and the slurry flow rate in the pipeline is fast, so the pipeline wears quickly and is prone to holes. Once a hole occurs in the pipeline, the slurry will leak and cause pollution to the surrounding environment. At the same time, the discharge end of the wear-resistant pipe is mostly located in the middle of the magnetic separator, so that the slurry in the middle of the magnetic separator is relatively concentrated, and the slurry in the magnetic separators at both ends is less. There are problems such as low efficiency in magnetic separator beneficiation and easy leakage in the slurry flow pipe. Therefore, it does not meet the existing needs. In this regard, a slurry flow distributor for connecting the cyclone and the large magnetic separator is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a slurry flow distributor for connecting a cyclone with a large magnetic separator. By arranging a guide plate between the cyclone discharge pipe and the magnetic separator feed box, and arranging a first diverter plate and a second diverter plate on the guide plate, the slurry flows along the guide plate to the interior of the magnetic separator feed box, wherein the first diverter plate and the second diverter plate cooperate to evenly divide the slurry, so that the slurry flows evenly into the interior of the magnetic separator, thereby improving the ore dressing efficiency and solving the problems in the prior art.

[0012] 1. The utility model arranges a guide plate between the cyclone discharge pipe and the magnetic separator feed box, and arranges a first diverter plate and a second diverter plate above the guide plate. The slurry falls from the cyclone discharge pipe onto the guide plate, then flows along the guide plate, passes through the first diverter plate and the second diverter plate in sequence, and falls into the magnetic separator feed box.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In order to solve the problems of low efficiency of magnetic separator and leakage of slurry flow pipes, please refer to Figure 1-4 The utility model provides an embodiment: a slurry flow distributor for connecting a cyclone and a large magnetic separator, comprising a guide plate 101, and also comprising a first diverter plate 2 and a second diverter plate 3. The first diverter plate 2 and the second diverter plate 3 are both arranged on the side of the guide plate 101. The guide plate 101 has a trumpet-shaped structure, one end of the guide plate 101 is a wide mouth, and the other end of the guide plate 101 is a narrow mouth. A bottom plate 102 connected to the guide plate 101 is provided at the wide mouth, and a cyclone discharge pipe 8 is provided above the narrow mouth, a first support plate 5 and a second support plate 6 are provided above the first diverter plate 2, a third support plate 7 is provided above the second diverter plate 3, and a magnetic separator feed box 4 is provided below the bottom plate 102.

[0021] A base 1 is provided under the guide plate 101, and baffles 103 are provided on the guide plate 101 and the bottom plate 102. The narrow opening of the guide plate 101 is higher than the wide opening. Slurry is provided inside the cyclone discharge pipe 8. Along the flow direction of the slurry, the slurry passes through the first diverter plate 2, the second diverter plate 3 and the magnetic separator feed box 4 in sequence. There are at least two first diverter plates 2, at least four second diverter plates 3, and at least five magnetic separator feed boxes 4. The four second diverter plates 3 divide the wide opening of the guide plate 101 into five channels, and the outlets of the five channels correspond to the five magnetic separator feed boxes 4 respectively.

[0022] The slurry falls from the cyclone discharge pipe 8 onto the guide plate 101, then flows along the guide plate 101, passes through the first diverter plate 2 and the second diverter plate 3 in sequence, and falls into the inside of the magnetic separator feed box 4, wherein the first diverter plate 2 and the second diverter plate 3 cooperate to divide the slurry into five tributaries, and the five tributaries flow into the inside of the five magnetic separator feed boxes 4 respectively, so that the slurry can flow evenly into the inside of the magnetic separator, thereby improving the ore dressing efficiency; at the same time, compared with the traditional slurry flowing in the wear-resistant pipe, the slurry is evenly divided, which also reduces the speed at which the flow area is worn by the slurry, further improving the service life of the equipment.

[0023] The upper end of the second diverter plate 3 is connected to the third support plate 7, and the lower end of the second diverter plate 3 is connected to the guide plate 101. A column 201 is provided at one end of the first diverter plate 2, and a first turntable 202 and a fixed seat 203 are provided at the upper and lower ends of the column 201 respectively. The bottom of the first turntable 202 is axially connected to the column 201, and the top of the first turntable 202 is connected to the first support plate 5, and the fixed seat 203 is axially connected to the column 201. A slide 601 is provided inside the second support plate 6, and a slider 602 is provided inside the slide 601. A second turntable 603 is provided below the slider 602, and a clamping seat 604 is provided below the second turntable 603. The clamping seat 604 is connected to the first diverter plate 2, and the clamping seat 604 is axially connected to the second turntable 603.

[0024] When the clamping seat 604 moves along the slide 601, the first diverter plate 2 rotates with the column 201 as the center, which can change the opening and closing angle of the first diverter plate 2 and the vertical plane, and then change the flow rate of the slurry on both sides of the first diverter plate 2, thereby improving flexibility. At the same time, when the mineral material in the slurry is blocked between the first diverter plate 2 and the baffle 103, the opening and closing angle of the first diverter plate 2 can also be increased to release the blocked mineral material, thereby ensuring the normal flow of the slurry and further improving the subsequent mineral processing efficiency.

[0025] Working principle: The slurry flows along the guide plate 101, passes through the first diverter plate 2 and the second diverter plate 3 in sequence, falls into the inside of the magnetic separator feed box 4, and finally enters the inside of the magnetic separator to start material selection. The first diverter plate 2 and the second diverter plate 3 cooperate to divide the slurry into five tributaries, and the five tributaries flow into the inside of the five magnetic separator feed boxes 4 respectively, so that the slurry can flow evenly into the inside of the magnetic separator, thereby improving the mineral separation efficiency.
