Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and specifically provides a magnetic medium wet feeding silo. Background Technology

[0002] Magnetic separation wastewater treatment works by using magnetic media to adsorb pollutants in wastewater, causing the pollutants to form flocs with the magnetic media. These flocs then separate and enter a magnetic separation device, which adsorbs the magnetic media, separating both the magnetic media and the flocs bound to it from the wastewater. After separation, the magnetic media is recovered from the flocs in subsequent processes and reused in upstream processes. Therefore, the magnetic media is recycled throughout the entire wastewater treatment system.

[0003] However, some magnetic media in wastewater treatment systems are always not successfully recovered, and a certain proportion of magnetic media is always lost. To ensure sufficient magnetic media content in the wastewater treatment system, a feeding device is installed to replenish the magnetic media. Existing feeding methods can be divided into dry feeding and wet feeding. In wet feeding, because the magnetic media has a certain moisture content, in a closed environment and during flow, the moisture on the surface of the magnetic media will form water vapor. When the water vapor comes into contact with the low-temperature top cover, it will form condensate. The condensate drips into the magnetic media under the action of gravity. The moisture inherent in the magnetic media is usually evenly distributed or adsorbed inside / on the surface of the particles, forming a stable state. However, the condensate wetting of the magnetic media is a dynamic process. Repeated wetting-drying cycles will intensify the bonding strength between particles, causing the magnetic media to clump together, making it unable to flow and clogging the silo. Utility Model Content

[0004] This utility model provides a magnetic medium wet replenishment hopper to solve the problem that condensation will form on the top cover of the hopper in the wet replenishment method, and the condensation will drip into the magnetic medium and cause it to clump and become unable to flow, thus clogging the hopper.

[0005] The technical solution of this utility model is as follows:

[0006] A magnetic medium wet replenishment silo includes a silo body, a dehumidification device, and a heating device. The silo body has an internal cavity for containing magnetic medium. The heating device is located inside the silo body and is used to heat the inner surface of the silo body to prevent water vapor from condensing inside the silo body. The dehumidification device is located inside the silo body to remove water vapor from the silo body.

[0007] In this design, the heating device maintains a high temperature within the silo, preventing condensation. Water vapor evaporating from the silo is eliminated by a dehumidifier, preventing condensation due to excessive humidity and thus avoiding the problems of magnetic media caking and silo blockage. The dehumidifier condenses the water vapor inside the silo and then discharges the condensed liquid outside, effectively reducing humidity within the silo.

[0008] To facilitate the maintenance, cleaning, and addition of magnetic media to the silo, the silo body includes a hopper and a top cover. The hopper has an opening facing a certain direction, and the top cover is connected to the top of the hopper and is used to close the opening of the hopper.

[0009] In this solution, the top cover can be opened to perform maintenance, cleaning, and magnetic media addition to the hopper. After opening the top cover, magnetic media can be added into the hopper through the opening, and the inside of the hopper can also be maintained and cleaned.

[0010] To address the problem of damage to the heating device caused by friction between the magnetic medium and the side wall of the chamber, the heating device is installed on the top cover.

[0011] In this design, the contact area between water vapor and the top cover is larger, making it easier for condensation to form at the top cover. Therefore, the heating device is placed on the top cover so that it can be directly heated, preventing water vapor from condensing upon contact with the top cover. The inner side of the top cover is in contact with the hopper, and the heat from the top cover is conducted to the hopper, raising the temperature of the inner side of the hopper as well. This also prevents condensation from forming on the inner side of the hopper.

[0012] The size of the top cover is adapted to the size of the hopper. The top cover is usually large, making it difficult to open it to add magnetic medium. Therefore, the top cover is provided with a feeding port and a cover plate, which is used to close the feeding port.

[0013] In this design, a feeding port and a cover plate are installed on the top cover. When it is necessary to add magnetic media to the silo, the cover plate can be opened to add the magnetic media into the silo through the feeding port. Compared to opening the top cover, opening the cover plate is simpler, more convenient, and easier to operate.

[0014] Preferably, a sealing structure is provided between the top cover and the hopper, the sealing structure being used to seal the connection between the top cover and the hopper from the outside.

[0015] In this design, the sealing structure prevents external dust and other impurities from entering the chamber, thus avoiding the magnetic medium from hardening due to the presence of dust and other impurities.

[0016] The magnetic medium is located inside the silo. When the magnetic medium is needed, it needs to be taken out of the silo. If it is taken out directly from the top of the silo, it will consume manpower and the labor intensity of workers will be high. Therefore, the silo is provided with a discharge port, which is located at the bottom of the silo.

[0017] In this solution, the magnetic medium inside the silo can automatically flow to the outlet position and be discharged from the outlet under the action of gravity, eliminating the need for a mechanism to transport the magnetic medium inside the silo, thus simplifying the silo structure and reducing the cost of the silo.

[0018] Preferably, the hopper body is further provided with support legs, which are connected to the outer side of the hopper body and are used to support the hopper body so that the discharge port is suspended in the air.

[0019] In this design, the hopper is supported by legs, allowing the discharge port to be suspended in the air, which facilitates the processing of the magnetic medium discharged from the discharge port. For example, a screw conveyor mechanism can be installed below the discharge port.

[0020] To address the inconvenience of transferring and transporting materials from the silo, a skid-mounted platform is also included, with the bottom of the support legs fixedly connected to the skid-mounted platform.

[0021] In this solution, by setting up a skid-mounted platform, the entire platform and its hopper can be directly transported to the site during transport, eliminating the need for on-site assembly and installation, thus reducing construction costs. Furthermore, placing the hopper on the skid-mounted platform allows for factory assembly, eliminating the need for on-site assembly and splicing. The factory has complete processing equipment, resulting in lower processing difficulty and costs.

[0022] To address the issue of inconvenient handling of skid-mounted platforms, lifting lugs are provided on the skid-mounted platforms.

[0023] In this solution, after the skid-mounted platform is equipped with lifting lugs, it can be lifted and transported by cranes or other devices, making it easy to transfer the skid-mounted platform to a transport vehicle or to other locations.

[0024] The required magnetic media content in the silo varies depending on the scale of wastewater treatment. If a separate silo is designed for each wastewater treatment system, additional design costs are required. Therefore, the silo also includes at least one expansion module. The expansion module is a cylindrical structure. The bottom of the expansion module is detachably connected to the hopper, and the top of the expansion module is connected to the top cover.

[0025] In this solution, when the silo's capacity is insufficient, the capacity can be increased by adding expansion modules to meet usage requirements. Furthermore, this silo expansion method does not require separate design, reducing silo design costs.

[0026] The beneficial effects of this utility model are:

[0027] This invention prevents condensation inside the chamber by heating the interior of the chamber and removes evaporated water vapor inside the chamber through a dehumidification device, thus preventing excessive water vapor content inside the chamber from condensing into water droplets and preventing the magnetic medium from hardening.

[0034] The technical solution of this utility model will be clearly and completely described in conjunction with the accompanying drawings and through specific embodiments.

[0035] Example 1:

[0036] like Figure 1 As shown in the figure, this embodiment provides a magnetic medium wet replenishment silo, including a silo body 1, a dehumidification device 2, and a heating device 5. The silo body 1 has an internal cavity for containing the magnetic medium. The heating device 5 is located inside the silo body 1 and is used to heat the inner side of the silo body 1, thereby increasing the temperature of the inner side of the silo body 1 and preventing water vapor evaporated from the magnetic medium from condensing on the inner wall of the silo body 1. The dehumidification device 2 is located in the silo body 1 and is used to eliminate water vapor inside the silo body 1, preventing excessive water vapor levels from causing water droplets to condense on the inner wall of the silo body 1.

[0037] The hopper 1 includes a hopper 11 and a top cover 12. The top of the hopper 11 has an opening, and the top cover 12 is connected to the top of the hopper 11 to close the opening. A cavity for containing magnetic media is located in the hopper 11. After the magnetic media is loaded into the hopper 11, the top cover 12 closes the top of the hopper 11 to prevent external dust, impurities, and moisture from entering the hopper 11.

[0038] The dehumidification device 2 can be a semiconductor dehumidification box. The function of the semiconductor dehumidification box is to exhaust the water vapor in the chamber 1 to the outside of the chamber 1, thereby eliminating the water vapor in the chamber 1.

[0039] The heating device 5 is an electric heating wire, which is attached to the inner side of the top cover 12 by adhesive bonding to heat the inner side of the top cover 12. When moisture evaporates from the magnetic powder, it used to condense on the top cover 12. Now, the moisture can be evaporated by heating the top cover 12 without condensation. The evaporated water vapor is dehumidified by semiconductor condensation and discharged outside the box.

[0040] A sealing structure is provided between the top cover 12 and the hopper 11. The sealing structure can be a sealing ring or a sealing strip 6. The sealing ring or sealing strip 6 is provided on the contact surface between the top cover 12 and the hopper 11 to achieve sealing of the cavity.

[0041] The top cover 12 is shaped to fit the top of the hopper 11, and the edge of the top cover 12 is provided with a downwardly extending side strip that covers the outer side wall of the top of the hopper 11 from the outside. The side strip prevents the top cover 12 from moving horizontally relative to the hopper 11. A sealing structure may be provided on the inner side of the side strip or on the outer side wall of the top of the hopper 11.

[0042] Alternatively, a sealing strip 6 can be installed on the top of the hopper 11. When the top cover 12 is placed on the top of the hopper 11, the top cover 12 presses the sealing strip 6 under the action of gravity, thus sealing the inside of the hopper 11.

[0043] The hopper 11 has at least three legs 3 on its side, which support the hopper 11 to the ground or other platform. The legs 3 can be profiles fixed to the side of the hopper 11, such as square steel or channel steel. The legs 3 can be fixed to the hopper 11 by welding or bolting.

[0044] The bottom of the hopper 1 has a discharge port that connects to the container cavity, allowing the magnetic medium inside the container to flow out under gravity. Support legs 3 on the side of the hopper 11 allow the discharge port to be suspended. When the discharge port is suspended, other conveying devices, such as screw conveyors or belt conveyors, can be installed below it. Containers such as buckets or basins can also be placed below the discharge port. A pipe can also be connected to the discharge port to transport the magnetic medium to the location where it needs to be replenished.

[0045] When it is necessary to add magnetic media to the bottom of the hopper 1, the top cover 12 needs to be opened, and then the magnetic media can be added or the interior of the hopper 11 can be inspected and maintained through the opening at the top of the hopper 11. The opening of the hopper 11 is relatively high, so a ladder 4 is provided on one side of the hopper 11. The operator can use the ladder 4 to move to the opening of the hopper 11, which makes it easier to add magnetic media into the hopper 11 or to inspect and maintain the interior of the hopper 11.

[0046] When the bottom of the support leg 3 is supported on the ground, the ladder 4 is also set on the ground. When the bottom of the support leg 3 is supported on another platform, the ladder 4 is also set on the corresponding platform. For example, the bottom of the support leg 3 is fixed to a skid-mounted platform 10, and the edge of the skid-mounted platform 10 can be provided with lifting lugs 9. When it is necessary to move it to a transport vehicle or other location, it can be moved by a crane or other lifting device. When the skid-mounted platform 10 is set, the medicine tank 8 can also be fixed on the skid-mounted platform 10. The discharge port of the hopper 11 is connected to the medicine tank through a pipe, and a valve can be set on the pipe to control the discharge of the hopper 11. After the magnetic medium is discharged from the hopper 11, it can be mixed with other medicines in the medicine tank 8.

[0047] An operating platform 7 is provided at the top of the ladder 4, and the platform is located on one side of the hopper 11. The top of the operating platform 7 is flat and wider than the width of the ladder 4, making it convenient for operators to stand and operate.

[0048] Example 2:

[0049] This second embodiment provides a magnetic medium wet replenishment hopper, which differs from the first embodiment in that the top cover 12 is different.

[0050] like Figure 2 As shown, the top cover 12 is provided with a feeding port and a cover plate 121. The feeding port is a hole that penetrates the top and bottom surfaces of the top cover 12, through which magnetic medium can be added to the hopper 11. When it is not necessary to add magnetic medium, the feeding port can be closed by the cover plate 121.

[0051] In this second embodiment, a feeding port and a cover plate 121 are provided, so that when the operator replenishes the magnetic medium, it is not necessary to remove the top cover 12, but only to remove the cover plate 121. Compared with moving the top cover 12, moving the cover plate 121 is simpler and more efficient.

[0052] The cover plate 121 and the top cover 12 can be connected by a hinge. A sealing strip can be provided on the edge of the cover plate 121. When the cover plate 121 closes the feeding port, a sealing effect is formed between the cover plate 121 and the top cover 12 through the sealing strip.

[0053] Similarly, the cover plate 121 can also be fixed to the top cover 12 by a hand-tightening nut. For example, a stud is provided on the top of the top cover 12, and a through hole is provided on the cover plate 121. When the cover plate 121 closes the feeding port, the stud passes through the through hole. Then, the hand-tightening nut is connected to the stud, and the hand-tightening nut is tightened so that the hand-tightening nut presses the cover plate 121 from the top, thereby fixing the cover plate 121.

[0054] The heating device 5 is not installed at the location of the feeding port on the top cover 12 to avoid obstructing the addition of the magnetic medium.

[0055] Example 3:

[0056] This embodiment three provides a magnetic medium wet replenishment hopper. Unlike embodiment one, the hopper 11 also includes an expansion module 111.

[0057] like Figure 3 As shown, the expansion module 111 is a cylindrical structure whose cross-sectional shape is adapted to the opening shape of the hopper 11. If the opening shape of the hopper 11 is square, then the expansion module 111 is a square tube structure with a square cross-section.

[0058] The hopper 11 has a horizontally extending flange at its opening, and the expansion module 111 also has flanges at both ends along its axial direction. After aligning the flanges of the hopper 11 opening with those of the expansion module 111, bolts can be used to pass through both flanges, and nuts and bolts can be used to fix the flanges of the hopper 11 and the expansion module 111, thus installing the expansion module 111 on top of the hopper 11 and achieving the effect of expanding the capacity of the hopper 11. Expansion modules 111 can also be connected to the top of the expansion module 111 to further increase the capacity of the hopper 11. With the expansion module 111 installed, the top cover 12 is connected to the uppermost expansion module 111, and a sealing structure is also provided on the expansion module 111.
