Description

Technical Field

[0001] This utility model relates to the field of Fenton oxidation reactor technology, specifically to the waste iron floc feeding structure in a Fenton oxidation reactor. Background Technology

[0002] A Fenton oxidation reactor is an advanced oxidation device for wastewater treatment. It utilizes the Fenton reaction principle to oxidize and decompose recalcitrant organic matter in wastewater. The core of the Fenton oxidation reactor, or simply Fenton reactor, lies in the Fenton reaction. Fenton reactors are particularly suitable for treating high-concentration, recalcitrant wastewater. They can be used as a biological pretreatment to improve water quality and enhance the biodegradability of wastewater, creating favorable conditions for subsequent advanced treatment. During operation, scrap iron flocs need to be added to the wastewater. This enhances the flocculation and trapping effect, effectively removing suspended solids and colloidal substances from the wastewater. The flocs adsorb suspended particles and colloidal substances, forming larger flocs, thus facilitating subsequent solid-liquid separation.

[0003] Currently, in order to save materials, and because the weight of accumulated scrap iron lint is relatively heavy, a scrap iron lint feeding structure is used when using a Fenton oxidation reactor. However, the current scrap iron lint feeding structure in the Fenton oxidation reactor cannot control or limit the amount fed, thus reducing the practicality of the scrap iron lint feeding structure in the Fenton oxidation reactor. Summary of the Invention

[0004] The purpose of this invention is to provide a waste iron flocculent feeding structure in a Fenton oxidation reactor, so as to solve the problem of low practicality of the current waste iron flocculent feeding structure in the Fenton oxidation reactor.

[0021] 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.

[0022] Example: Figure 1 - Figure 5As shown, this utility model provides a technical solution for the waste iron floc feeding structure in a Fenton oxidation reactor, including a device body 1, a feeding hopper 2 inside the device body 1, an installation groove 3 formed at the bottom opening of the feeding hopper 2, a limiting plate 4 rotatably connected to both inner walls of the installation groove 3, a threaded rod 5 rotatably connected to both inner walls of the installation groove 3, an adjusting rod 6 threadedly sleeved on the outer side of the threaded rod 5, a round rod 7 fixedly connected to the movable end of the adjusting rod 6, a sliding groove 8 provided on opposite sides of the two limiting plates 4, a wire groove evenly distributed on both inner walls of the sliding groove 8, the two ends of the round rod 7 sliding in the cavities of the two wire grooves respectively, a stabilizing rod fixedly connected to both sides of the adjusting rod 6, the end of the stabilizing rod having a semi-circular structure, and the end of the stabilizing rod contacting the side of the limiting plate 4;

[0023] A drive device for moving the device can be installed on the device body 1, or installed on the drive device, so as to facilitate moving the device body 1 and feeding materials; the drive device can be existing equipment and machinery such as drive vehicles, depending on actual needs.

[0024] Scrap iron flakes are fed into the feeding hopper 2 and discharged through the bottom opening of the feeding hopper 2. When it is necessary to limit the discharge of scrap iron flakes, simply rotate the threaded rod 5. The threaded rod 5 drives the adjusting rod 6 to rise and fall. The adjusting rod 6 pushes the limiting plate 4 to rotate, thereby causing the movable ends of the two limiting plates 4 to move closer or further apart. Thus, the limiting plates 4 are used to limit the space at the bottom opening of the feeding hopper 2, thereby achieving the effect of limiting the discharge.

[0025] like Figure 1 and Figure 2 As shown, a feeding hopper 9 is installed on the upper part of the device body 1, and a sliding plate 10 is fixedly sleeved on the bottom of the feeding hopper 9. The upper part of the feeding hopper 2 is slidably connected to the bottom of the sliding plate 10, and the feeding hopper 2 is slidably connected to the inside of the device body 1. A rotating mechanism that drives the feeding hopper 2 to reciprocate is provided on the device body 1.

[0026] like Figure 1 - Figure 3 As shown, the rotating mechanism includes a turntable 11 rotatably connected to the inner wall of the device body 1. A connecting rod 12 is rotatably connected to the off-axis center of the turntable 11. A reciprocating rod is rotatably connected to the movable end of the connecting rod 12. The end of the reciprocating rod is fixedly connected to the outer wall of one side of the feeding hopper 2.

[0027] The material is first fed into the feed hopper 9, and then fed from the feed hopper 9 to the feeding hopper 2. When feeding material into the feeding hopper 2, the turntable 11 is rotated, and the turntable 11 drives the feeding hopper 2 to slide back and forth through the connecting rod 12, thereby shaking the material inside the feeding hopper 2 to avoid material blockage.

[0028] like Figure 2 and Figure 3As shown, a servo motor 16 is installed on the inner wall of the device body 1, and the output end of the servo motor 16 is fixedly connected to the axis at the bottom of the turntable 11.

Two sleeves 14 are slidably sleeved on the outer side of the long rod 13. One end of the sleeve 14 has a through hexagonal cavity. A fixing plate 15 is rotatably sleeved on the outer side of the sleeve 14. The fixing plate 15 is fixedly connected to one side of the feeding hopper 2. A first pulley is rotatably connected to the fixing plate 15. A bevel gear 18 is fixedly installed on the upper part of the first pulley and the end of the sleeve 14. The two bevel gears 18 are arranged perpendicular to each other and mesh with each other. A second pulley is fixedly sleeved on the bottom end of the threaded rod 5. A chain belt 17 is connected between the second pulley and the first pulley.

[0031] By rotating the long rod 13, the long rod 13 drives the sleeve 14 to rotate, and the sleeve 14 drives the first pulley to rotate through two corresponding bevel gears 18. The first pulley drives the threaded rod 5 to rotate through the chain belt 17, thus causing the two threaded rods 5 to rotate together, and causing the adjusting rods 6 on the two threaded rods 5 to move in the same direction.

[0032] like Figure 1 - Figure 3 As shown, track grooves 21 are formed on both inner walls of the device body 1, and track rods 19 are fixedly connected to both sides of the feeding hopper 2. The track rods 19 slide in the cavity of the track grooves 21. The vertical cross section of the track rods 19 is a convex-shaped structure, and the vertical cross section of the track grooves 21 is a convex-shaped cavity.

[0033] The track rod 19 and track groove 21 can stabilize the feeding hopper 2 and limit the range of motion of the feeding hopper 2.
