Description

Technical Field

[0001] This utility model relates to the technical field of centrifugal dewatering equipment, specifically to a centrifugal dewatering device for antimony ore flotation concentrate. Background Technology

[0002] In the field of antimony ore beneficiation, dewatering of flotation concentrate is a crucial step. The effectiveness of concentrate dewatering directly affects the efficiency and cost of subsequent smelting and processing, and also has significant implications for environmental protection. Currently, common methods for dewatering antimony ore flotation concentrate include centrifugal dewatering, filtration dewatering, and pressure filtration dewatering. Among these, centrifugal dewatering technology is widely used in mining, metallurgy, and chemical industries due to its advantages such as large processing capacity, high efficiency, and simple operation.

[0003] In the dewatering process of antimony ore flotation concentrate, a small amount of flotation foam in the slurry easily forms in parts such as the feed pipe. Furthermore, solid matter in the slurry tends to accumulate and cause blockages at the connection between the feed pipe and the dewatering device, affecting normal feeding and consequently impacting the normal operation and dewatering efficiency of the dewatering unit. Therefore, developing a centrifugal dewatering device for antimony ore flotation concentrate that can effectively solve the feed pipe cleaning problem and optimize the foam flushing process is of significant practical importance. Utility Model Content

[0004] The purpose of this utility model is to provide a centrifugal dewatering device for antimony ore flotation concentrate, in order to solve the problem mentioned in the background art that during the dewatering process of antimony ore flotation concentrate, due to the presence of a small amount of foam and a high solid content in the slurry, blockage and foam overflow are prone to occur in parts such as the feed pipe, which affects the normal feeding of the dewatering device.

[0005] To achieve the above objectives, this utility model provides a centrifugal dewatering device for antimony ore flotation concentrate, including a feed pipe. One end of the feed pipe is connected to different centrifuge tanks through several discharge hoses. A flushing port is provided at the upper part of one end of the feed pipe. A water supply pipe is provided above the feed pipe. A foam flushing pipe is installed at one end of the water supply pipe near the flushing port. A diversion pipe is connected to one side of the foam flushing pipe. A flushing pipe is connected to the lower end of the diversion pipe. The lower end of the flushing pipe is aligned with the inside of the flushing port.

[0006] This setup achieves batch processing by diverting feed to multiple centrifuge tanks via a feed pipe, while simultaneously utilizing branched water pipes to form a dual cleaning structure of foam flushing pipe and rinsing pipe: the foam flushing pipe cleans up the foam accumulated at the feed pipe, and the rinsing pipe reaches directly into the feed pipe through the rinsing port to remove solid matter accumulated in the slurry.

[0007] Preferably, a first valve is installed on the foam flushing pipe, and a second valve is installed on the diversion pipe.

[0008] This setup includes a first valve that controls the flow and interruption of water in the foam flushing pipe, and a second valve that regulates the amount of water from the diversion pipe to the flushing pipe.

[0009] Preferably, a discharge valve is installed on the discharge hose.

[0010] This setting allows for independent control of the opening and closing of each discharge hose via a discharge valve.

[0011] Preferably, the centrifuge tank is equipped with a cover plate on top, and a feed pipe is installed in the middle of the cover plate. The upper end of the feed pipe is connected to the discharge hose, and the lower end of the feed pipe is connected to a drain bend.

[0012] This feature includes a cover plate to seal the centrifuge tank and prevent slurry splashing. The feed pipe, in conjunction with the diversion bend, guides the slurry to flow along the side wall of the filter bag inside the centrifuge tank. The outlet of the diversion bend faces the side wall of the filter bag inside the centrifuge tank. During feeding, the filter bag rotates with the centrifugal disc, ensuring that the slurry is fed evenly along the filter bag.

[0013] Preferably, the water pipe is inclined, with an angle of 5-10° with the horizontal direction.

[0014] This setting involves tilting the water pipe at a 5-10° angle to utilize gravity to assist water flow.

[0015] Preferably, the flushing pipe is inclined from top to bottom.

[0016] This feature involves a flushing pipe that slopes downwards to create a directional water flow.

[0017] Preferably, the centrifuge tank is equipped with a centrifuge disc, which is driven to rotate by a motor.

[0018] This feature uses a motor to drive a centrifugal disc to rotate at high speed, using centrifugal force to separate water from the concentrate.

[0019] Preferably, the outer wall of the centrifuge tank is wrapped with a sound insulation layer, which is made of polyurethane foam material and has a thickness of 3-5 cm.

[0020] This feature involves wrapping the centrifuge tank with a 3-5cm polyurethane foam sound insulation layer, utilizing its porous structure to absorb sound waves.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: In this antimony ore flotation concentrate centrifugal dewatering device, a combination of water supply pipes, foam flushing pipes, and rinsing pipes allows for targeted flushing of the feed pipe and surrounding area. The foam flushing pipes effectively remove flotation foam buildup near the feed pipe, while the rinsing pipes directly flush the inside of the feed pipe through the rinsing port. This significantly reduces blockages caused by foam buildup and solid matter accumulation in the slurry, lowers equipment maintenance frequency, and improves continuous operation stability.

[0022] The configuration of the first valve, the second valve, and the discharge valve allows for flexible control of the on / off state and flow rate of each pipeline according to actual production needs. It can perform foam cleaning or internal rinsing independently, or operate in concert to adapt to cleaning and discharge requirements under different working conditions, thereby improving the operational flexibility of the device.

[0023] The centrifuge tank, in conjunction with the internal motor-driven centrifugal disc, can efficiently dewater concentrate. The guide bend at the lower end of the feed pipe can guide the slurry smoothly into the centrifuge tank and distribute it evenly, avoiding splashing and uneven distribution caused by direct impact, and ensuring uniform and stable centrifugal dewatering effect. At the same time, the discharge pipe is connected to different centrifuge tanks through multiple sets of discharge hoses, which can realize batch or parallel processing and improve the overall processing efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a centrifugal dewatering device for antimony ore flotation concentrate, such as... Figure 1 , Figure 2As shown, it includes a discharge pipe 1, one end of which is connected to different centrifuge tanks 4 through several discharge hoses 3. A flushing port 11 is provided at the upper part of one end of the discharge pipe 1. A water supply pipe 2 is provided above the discharge pipe 1. A foam flushing pipe 21 is installed at one end of the water supply pipe 2 near the flushing port 11. A diversion pipe 22 is connected to one side of the foam flushing pipe 21. A flushing pipe 23 is connected to the lower end of the diversion pipe 22. The lower end of the flushing pipe 23 is aligned with the inside of the flushing port 11.

[0027] Antimony ore flotation concentrate is diverted to multiple centrifuge tanks 4 via feed pipe 1 for batch processing. Simultaneously, a foam flushing pipe 21 and a flushing pipe 23 connected via a diversion pipe 22 are installed on the water supply pipe 2, forming a dual cleaning structure: the foam flushing pipe 21 cleans up the foam accumulated at the feed pipe, and the flushing pipe 23 reaches directly into the feed pipe through the flushing port to remove solid matter accumulated in the slurry. This achieves a combination of concentrate dispersion and dewatering and targeted cleaning, which improves processing efficiency through multiple centrifuge tanks 4 and reduces the risk of blockage in feed pipe 1, ensuring smooth feed flow.

[0028] In this embodiment, as Figure 2 As shown, a first valve 211 is installed on the foam flushing pipe 21, and a second valve 221 is installed on the diversion pipe 22.

[0029] The first valve 211 controls the flow and interruption of water in the foam flushing pipe 21, while the second valve 221 regulates the water volume from the diversion pipe 22 to the flushing pipe 23. The flushing function can be activated individually or in combination according to actual working conditions, flexibly adapting to different cleaning needs and saving water resources.

[0030] Specifically, such as Figure 1 As shown, a discharge valve 31 is installed on the discharge hose 3.

[0031] The discharge valve 31 independently controls the opening and closing of each discharge hose 3. This enables feed control of different centrifuge tanks 4, and allows for the independent start / stop of a single centrifuge tank 4 for maintenance or adjustment of processing capacity, improving the operational flexibility of the equipment.

[0032] Furthermore, such as Figure 3 As shown, a cover plate 41 is installed on the top of the centrifuge tank 4, and a feed pipe 42 is installed in the middle of the cover plate 41. The upper end of the feed pipe 42 is connected to the discharge hose 3, and the lower end of the feed pipe 42 is connected to the drain bend 43.

[0033] The cover plate 41 seals the centrifuge tank 4 to prevent slurry splashing, and the feed pipe 42, together with the guide bend 43, guides the slurry to flow along the side wall of the filter bag inside the centrifuge tank. This ensures a clean working environment and avoids uneven distribution caused by direct impact of slurry on the internal components of the centrifuge tank 4, thereby improving the uniformity and efficiency of centrifugal dewatering.

[0034] Furthermore, such as Figure 1As shown, water pipe 2 is installed at an angle of 5-10° with the horizontal direction.

[0035] The water supply pipe 2 is set at an angle of 5-10° to utilize gravity to assist water flow. This increases the water pressure and enhances the water flow impact force of the foam flushing pipe 21 and the rinsing pipe 23, thereby optimizing the cleaning effect.

[0036] Furthermore, such as Figure 2 As shown, the flushing pipe 23 is inclined from top to bottom.

[0037] The flushing pipe 23 slopes downwards, creating a directional water flow. This allows the flushing water to precisely enter the flushing port 11, enhancing the flushing force inside the feed pipe 1 and improving the efficiency of impurity removal.

[0038] Furthermore, a centrifuge disc is installed inside the centrifuge tank 4, and the centrifuge disc is rotated by a motor.

[0039] The motor drives the centrifugal discs inside centrifuge tank 4 to rotate at high speed, using centrifugal force to separate water from the concentrate. This mechanical centrifugal action achieves highly efficient dewatering, processing faster than traditional filtration methods and making it suitable for dewatering high-concentration slurries.

[0040] Furthermore, the outer wall of the centrifuge tank 4 is wrapped with a sound insulation layer made of polyurethane foam material with a thickness of 3-5cm.

[0041] A 3-5cm layer of polyurethane foam sound insulation is wrapped around the outer wall of the centrifuge tank 4, utilizing its porous structure to absorb sound waves. Effect: Significantly reduces noise generated by the motor and centrifuge operation, improves the working environment, and meets occupational health and safety standards.

[0042] The antimony ore flotation concentrate centrifugal dewatering device of this invention achieves efficient dewatering and anti-clogging through a synergistic mechanism of diversion conveying, centrifugal separation, and directional cleaning. The core principles include: Diversion and batch processing: The antimony ore flotation concentrate is diverted to multiple centrifuge tanks 4 using the feed pipe 1, and the processing capacity is increased by operating multiple tanks in parallel; the discharge hose 3 and discharge valve 31 enable independent control of each centrifuge tank 4, flexibly adapting to different working conditions. Centrifugal dehydration: The centrifugal disc inside centrifuge tank 4 is driven by a motor to rotate at high speed. With the help of centrifugal force, the water in the concentrate is separated from the solid particles. The water is filtered out through the filter bag inside the centrifuge tank, while the concentrate is retained in the tank. Targeted cleaning: Water supply pipe 2 provides a clean water source, forming a dual cleaning circuit through foam flushing pipe 21 and flushing pipe 23: foam flushing pipe 21 removes flotation foam from the upper part of feed pipe 1, making it easier to observe the feeding situation; flushing pipe 23 reaches the inside of feed pipe 1 through flushing port 11 to flush impurities. Combined with the inclined design of the pipeline, water supply pipe 2 is inclined at 5-10° and flushing pipe 23 is inclined from top to bottom to enhance the water flow impact force and reduce the risk of blockage. Auxiliary optimizations: Cover plate 41 prevents slurry splashing, and diversion bend 43 guides the slurry to flow smoothly into centrifuge tank 4 to ensure uniform dewatering; the 3-5cm polyurethane foam sound insulation layer on the outside of centrifuge tank 4 absorbs operating noise and improves the working environment. Work process Feed preparation: Open the discharge valve 31. The antimony ore flotation concentrate is transported through the feed pipe 1 and enters the centrifuge tank 4 through the discharge hose 3 and the feed pipe 42. The guide bend 43 guides the slurry to the side wall of the filter bag inside the centrifuge tank to avoid direct impact on the centrifuge disc and ensure uniform distribution of the slurry. Centrifugal dewatering: The motor is started to drive the centrifugal disc in the centrifugal tank 4 to rotate at high speed. Under the action of centrifugal force, the water in the slurry is separated and discharged through the filter bag in the centrifugal tank. The concentrate particles are deposited in the tank under the action of centrifugal force, completing the dewatering process. The cover plate 41 seals the tank opening to prevent slurry from splashing and polluting the environment. Cleaning and maintenance: When foam accumulates in the feed pipe 1, the first valve 211 is opened, and water in the water supply pipe 2 flows through the foam flushing pipe 21 and sprays out to remove surface foam in a directional manner. When blockage or scale buildup occurs inside the feed pipe 1, the second valve 221 is opened, and water flows through the diversion pipe 22 into the flushing pipe 23. The water then directly flushes the inside of the feed pipe 1 through the flushing port 11. The inclined design of the water supply pipe 2 enhances the water pressure and effectively removes the blockage. The first valve 211 and the second valve 221 can be opened individually or simultaneously as needed to flexibly adjust the cleaning intensity. Operation adjustment and shutdown: If maintenance is required on a centrifuge tank 4, the feeding of that tank can be stopped by closing the discharge valve 31 on the corresponding discharge hose 3, while other centrifuge tanks 4 can continue to operate; throughout the process, the sound insulation layer on the outside of the centrifuge tank 4 continuously reduces the noise generated by the motor and centrifugal operation, ensuring that the working environment meets the standards.

[0043] Finally, it should be noted that the electronic components in the centrifuge tank 4 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires.
