Description

Technical Field

[0001] This utility model relates to the field of iron concentrate, specifically to a pressure filtration device for dehydrating iron concentrate. Background Technology

[0002] Iron concentrate, also known as iron powder or iron ore concentrate, is a mineral powder produced from iron ore containing iron elements or iron compounds through crushing, grinding, and beneficiation. Iron concentrate dewatering is the process of separating solid materials from water to reduce the moisture content of wet materials. The moisture content of concentrate is one of the standards for measuring concentrate quality. The use of pressure filtration devices in the iron concentrate dewatering process can significantly improve dewatering efficiency, enhance dewatering effect, adapt to different particle sizes, save energy and protect the environment, and increase the degree of automation. These advantages have led to the widespread application of pressure filtration devices in the field of iron concentrate dewatering.

[0003] A search revealed a disc pressure filter for dewatering iron concentrate, with publication number CN217526505U. Specifically, this filter includes a filter body with a feed cylinder fixedly connected to its outlet. A rotating drum, driven by a first motor, is located above the feed cylinder. A reciprocating fixed rod is located inside the rotating drum, and multiple crushing blades are fixedly connected around the outside of the fixed rod. The advantages of this invention are: two discharge cylinders are fixedly connected below the feed cylinder, both communicating with it and tilted outwards in a V-shape, allowing material to slide out from different directions. A lifting cylinder is located in the middle of the bottom surface of the feed cylinder, with a sealing plate at its output end. The sealing plate can seal the two discharge cylinders, facilitating material control. The up-and-down movement of the sealing plate can clear the material, preventing accumulation and blockage.

[0004] Existing pressure filtration devices for iron concentrate dehydration simply rely on the rotation of a drum carrying the iron concentrate to complete the dehydration process. This method is time-consuming, inefficient, and results in insufficient dryness of the iron concentrate, affecting subsequent processing and usage. Furthermore, the pressure filtration devices for iron concentrate dehydration in the aforementioned comparative case also lack methods to enhance the pressure filtration effect. Consequently, the equipment has poor adaptability under long-term use, making it unable to handle iron concentrate with different particle sizes and moisture contents, thus limiting the equipment's applicability and flexibility.

[0005] Therefore, it is necessary to invent a pressure filtration device for dehydrating iron concentrate to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a pressure filtration device for dehydrating iron concentrate. By employing a hot air pressure pump, an impurity filter screen, a telescopic cylinder, a dehydration plate, a vacuum conveying pump, a dehydration filter barrel, and a centrifugal filter cartridge, the overall pressure filtration effect of the iron concentrate dehydration device is enhanced. The combined action of the pressurized hot air, the dehydration plate, and the centrifugal filter cartridge makes it easier to remove moisture from the iron concentrate, resulting in a higher degree of dryness in the final iron concentrate. Furthermore, this design enhances the adaptability of the equipment, enabling it to handle iron concentrate with different particle sizes and moisture contents. It exhibits strong adaptability and flexibility, and can significantly improve... The goal is to improve dehydration efficiency and quality, reduce energy consumption and costs, and address the shortcomings of existing pressure filtration devices for iron concentrate dehydration. These devices rely solely on rotating a drum carrying the iron concentrate to achieve dehydration, resulting in long dehydration times, low efficiency, and insufficient dryness of the iron concentrate, impacting subsequent processing and use. Furthermore, the pressure filtration devices in the aforementioned comparative case lack methods to enhance pressure filtration, leading to poor adaptability and an inability to handle iron concentrates of varying particle sizes and moisture contents over long-term use, thus limiting the equipment's applicability and flexibility.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pressure filtration device for dehydrating iron concentrate, comprising a pressure filtration body and a main body for pressure filtration of iron concentrate for dehydration;

[0008] A hot gas pressurizing pump is installed above the pressurizing filter body to provide pressurized hot gas. An input pipe is fixedly installed at one end of the hot gas pressurizing pump. A pressure gauge is fixedly installed above the pressurizing filter body. A fixing bolt passes through the outside of the pressurizing filter body. An impurity filter screen is movably connected to one end of the fixing bolt. A telescopic cylinder is installed above the impurity filter screen. A dehydration plate is fixedly installed at one end of the telescopic cylinder.

[0009] A vacuum feed pump is installed outside the pressure filter body to extract iron concentrate from the filter screen. A feed pipe is fixedly installed at one end of the vacuum feed pump. A dewatering filter barrel is installed below the pressure filter body. A drive motor is installed at the bottom of the dewatering filter barrel. A centrifugal filter cylinder is fixedly installed at the output end of the drive motor.

[0010] Preferably, a support rod is fixedly installed on the top of the pressure filter body, a feed cylinder is fixedly installed inside the support rod, a servo motor is provided outside the feed cylinder, and a dispersing roller is fixedly installed at the output end of the servo motor.

[0011] Preferably, a feed pipe is fixedly installed at the bottom of the feed cylinder, a threaded rod passes through the outside of the feed pipe, and a spacer plate is provided outside the threaded rod.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model is equipped with a hot air pressurization pump, an impurity filter screen, a telescopic cylinder, dehydration plates, a vacuum conveying pump, a dehydration filter barrel, and a centrifugal filter cylinder. When using this pressurized filtration device for dehydrating iron concentrate, after the iron concentrate falls onto the impurity filter screen, a certain amount of pressurized hot air is introduced into the pressurized filter body through the hot air pressurization pump. This increases the internal temperature and pressure of the machine body, which helps to accelerate the evaporation and discharge of moisture in the iron concentrate. Then, the telescopic cylinder pushes two sets of dehydration plates to squeeze the iron concentrate back and forth on the impurity filter screen, which helps to evenly distribute and filter the iron concentrate. Finally, the iron concentrate that has been initially pressurized and filtered... The iron concentrate is drawn out by a vacuum pump and then fed into the centrifugal filter cartridge of the dewatering filter barrel. The high-speed rotation of the centrifugal filter cartridge performs secondary spun-dry filtration on the iron concentrate. This combination enhances the overall pressure filtration effect of the pressure filtration device for iron concentrate dewatering. The combined action of pressurized hot air, dewatering plates, and centrifugal filter cartridges makes it easier to remove moisture from the iron concentrate, resulting in iron concentrate with higher dryness. Moreover, this design enhances the adaptability of the equipment, enabling it to handle iron concentrate with different particle sizes and moisture contents. It has strong adaptability and flexibility, which can significantly improve dewatering efficiency and quality, and reduce energy consumption and costs.

[0017] 2. This utility model is equipped with a support rod, a feeding cylinder, a servo motor, a dispersing roller, a discharge pipe, a threaded rod, and a partition plate. When using this pressure filtration device for dehydrating iron concentrate, the iron concentrate containing moisture can be first fed into the feeding cylinder. It is then dispersed by the rotation of the dispersing roller inside the feeding cylinder. Then, the angle of the partition plate inside the discharge pipe can be adjusted by twisting the threaded rod to control the flow rate and velocity of the iron concentrate entering the pressure filter body. In this way, the pressure filtration device for dehydrating iron concentrate can first disperse the iron concentrate to prevent it from sticking together, which helps to distribute the moisture more evenly in the subsequent dehydration process, thereby improving the dehydration efficiency. Moreover, the adjustable flow rate discharge pipe allows the feeding speed of the iron concentrate to be adjusted according to actual needs, thereby further controlling the dehydration process and ensuring the stability of the dehydration quality.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5 The pressure filtration device shown includes a pressure filter body 1, which is the main body for pressure filtration of iron concentrate for dehydration.

[0028] A hot gas pressurizing pump 9 is installed above the pressurizing filter body 1 to provide pressurized hot gas. An input pipe 10 is fixedly installed at one end of the hot gas pressurizing pump 9. A pressure gauge 11 is fixedly installed above the pressurizing filter body 1. A fixing bolt 12 passes through the outside of the pressurizing filter body 1. An impurity filter screen 13 is movably connected to one end of the fixing bolt 12. A telescopic cylinder 14 is installed above the impurity filter screen 13. A dehydration plate 15 is fixedly installed at one end of the telescopic cylinder 14.

[0029] A vacuum feed pump 16 is installed outside the pressure filter body 1 to extract iron concentrate from the filter screen. A feed pipe 17 is fixedly installed at one end of the vacuum feed pump 16. A dewatering filter barrel 18 is installed below the pressure filter body 1. A drive motor 19 is installed at the bottom of the dewatering filter barrel 18. A centrifugal filter cylinder 20 is fixedly installed at the output end of the drive motor 19. The iron concentrate that has been initially pressurized and filtered inside the pressure filter body 1 is extracted by the vacuum feed pump 16 and then fed into the centrifugal filter cylinder 20 of the dewatering filter barrel 18. The high-speed rotation of the centrifugal filter cylinder 20 performs secondary spin-drying filtration on the iron concentrate. This combination enhances the overall pressurization and filtration effect of the pressure filter device for dewatering iron concentrate.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a support rod 2 is fixedly installed on the top of the pressure filter body 1. A feed cylinder 3 is fixedly installed inside the support rod 2. A servo motor 4 is installed outside the feed cylinder 3. A dispersing roller 5 is fixedly installed at the output end of the servo motor 4. The iron concentrate containing moisture is first fed into the feed cylinder 3. It is dispersed by the rotation of the dispersing roller 5 inside the feed cylinder 3 to prevent it from sticking together. This helps to distribute the moisture more evenly in the subsequent dewatering process, thereby improving the dewatering efficiency. A discharge pipe 6 is fixedly installed at the bottom of the feed cylinder 3. A threaded rod 7 passes through the outside of the discharge pipe 6. A partition plate 8 is installed outside the threaded rod 7. The angle of the partition plate 8 inside the discharge pipe 6 can be adjusted by twisting the threaded rod 7, thereby controlling the flow rate and velocity of the iron concentrate entering the pressure filter body 1.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, the impurity filter screen 13 is threadedly connected to the pressure filter body 1, and the dewatering plate 15 is fixedly connected to the telescopic cylinder 14. When iron concentrate falls onto the impurity filter screen 13, a certain amount of pressurized hot air is input into the pressure filter body 1 via the hot air pressurization pump 9. This increases the internal temperature and pressure of the machine, helping to accelerate the evaporation and discharge of moisture from the iron concentrate. Then, the telescopic cylinder 14 pushes the two sets of dewatering plates 15 to repeatedly squeeze the iron concentrate on the impurity filter screen 13, which helps to ensure the uniform distribution and filtration of the iron concentrate. The centrifugal filter cartridge 20 and the dewatering filter barrel 18... The dewatering filter barrel 18 is fixedly connected to the pressure filter body 1. The iron concentrate powder after initial pressure filtration is extracted by the vacuum feed pump 16 and then fed into the centrifugal filter cylinder 20 of the dewatering filter barrel 18. The iron concentrate powder is subjected to secondary spin-drying filtration by the high-speed rotation of the centrifugal filter cylinder 20. The dewatering filter barrel 18 is fixedly installed with a discharge pipe 21. The bottom of the dewatering filter barrel 18 is provided with a collection box 22. The iron concentrate powder after dewatering and spin-drying flows out through the discharge pipe 21 and enters the collection box 22 for unified storage, so as to facilitate external operators to take it out.

[0032] The working principle of this practical device is as follows: First, connect the external power supply and take out the iron concentrate powder to be dehydrated and pressure filtered. First, uniformly feed the iron concentrate powder into the feed cylinder 3. Then, turn on the servo motor 4, causing the servo motor 4 to drive the dispersing roller 5 to rotate. The iron concentrate powder is dispersed by the rotation of the dispersing roller 5 inside the feed cylinder 3. Next, the angle of the partition plate 8 inside the feed pipe 6 can be adjusted by twisting the threaded rod 7 to control the flow rate and velocity of the iron concentrate powder entering the pressure filter body 1. In this way, the pressure filter device for iron concentrate dehydration first disperses the iron concentrate powder to prevent it from sticking together, which helps to distribute the moisture more evenly in the subsequent dehydration process. The adjustable flow feed pipe 6 allows for adjustment of the iron concentrate feed speed according to actual needs, thereby further controlling the dehydration process and ensuring the stability of dehydration quality. The iron concentrate then enters the pressure filter body 1 and falls onto the impurity filter screen 13. The hot air pressurization pump 9 can be turned on, and according to the pressure gauge 11, a certain amount of pressurized hot air is input into the pressure filter body 1 via the hot air pressurization pump 9. This increases the internal temperature and pressure of the machine, helping to accelerate the evaporation and discharge of moisture from the iron concentrate. Subsequently, the telescopic cylinder 14 is turned on, pushing the two sets of dehydration plates 15 onto the impurity filter screen 13. The iron concentrate is repeatedly squeezed, which helps to evenly distribute and filter it. Then, the vacuum feed pump 16 is turned on, allowing the iron concentrate, which has been initially pressurized and filtered, to be drawn out by the vacuum feed pump 16 and the feed pipe 17 and fed into the centrifugal filter cylinder 20 of the dewatering filter tank 18. Next, the drive motor 19 at the bottom of the dewatering filter tank 18 can be turned on, and the iron concentrate is subjected to secondary spin-drying filtration by the high-speed rotation of the centrifugal filter cylinder 20. This enhances the overall pressurized filtration effect of the iron concentrate dewatering pressurized filtration device. The combined action of the pressurized hot air, the dewatering plate 15, and the centrifugal filter cylinder 20 makes it easier for the moisture in the iron concentrate to be discharged. The resulting iron concentrate has a higher degree of dryness. After dehydration, spin drying, and filtration, the iron concentrate flows out through the discharge pipe 21 and enters the collection box 22 for unified storage, making it convenient for external operators to retrieve. Finally, after completing the installation and use of the pressure filtration device for dehydrating iron concentrate according to the above operations, turn off the switch of the servo motor 4, the switch of the hot air pressure pump 9, the switch of the telescopic cylinder 14, the switch of the vacuum conveying pump 16, and the switch of the drive motor 19. If it is not used for a long time, simply disconnect the external power supply. In this way, the use of the pressure filtration device for dehydrating iron concentrate is completed.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
