Description

Technical Field

[0001] This utility model relates to the field of heating mechanism technology, and in particular to a thickener heating mechanism. Background Technology

[0002] In the field of chemical wastewater treatment, thickeners, as a commonly used solid-liquid separation device, are widely used in the treatment of various industrial wastewaters. They can effectively concentrate and clarify wastewater, improving resource recovery and utilization rates. Yellow phosphorus wastewater generated during yellow phosphorus production contains a large amount of residual yellow phosphorus. Direct discharge of this wastewater not only wastes resources but also causes serious environmental pollution. Therefore, the recovery and utilization of yellow phosphorus from yellow phosphorus wastewater has significant economic and environmental implications.

[0003] Currently, a significant technical challenge exists in treating yellow phosphorus wastewater using thickeners. Yellow phosphorus has a melting point of only 44.1℃, and it readily solidifies at room temperature, making it difficult to effectively separate and recover from the wastewater within the thickener. Traditional thickeners cannot provide a stable and suitable temperature environment for the yellow phosphorus wastewater, resulting in the yellow phosphorus remaining in a solidified state, severely impacting the efficiency of yellow phosphorus recovery and increasing subsequent treatment costs and process complexity. Therefore, this invention proposes a thickener heating mechanism. Utility Model Content

[0004] The purpose of this invention is to address the problem in the background art that when traditional thickeners treat yellow phosphorus wastewater, they cannot provide a stable and suitable temperature environment, making it difficult to effectively separate and recover yellow phosphorus, which has a low melting point and is easily solidified, thus affecting recovery efficiency and increasing treatment costs and process difficulty. The invention proposes a thickener heating mechanism.

The two sets of connecting plates are located on the side of the two sets of positioning frames that are far apart from each other. A combination plate is provided on the side of the two sets of connecting plates near the rotating shaft. Multiple sets of first screws are fixedly connected to the combination plate. The first screws pass through the connecting plate and are threaded with a first nut.

[0008] Optionally, the fixing assembly further includes a fixing plate disposed on the side of the combination plate near the rotating shaft. The fixing plate is fixedly connected to the rotating shaft. Multiple sets of second screws are installed on the side of the fixing plate. The second screws pass through the combination plate and the connecting plate and are threadedly connected to a second nut.

[0009] Optionally, the centralizing mechanism includes two concentrically arranged centralizing boxes. The centralizing boxes are circular and hollow.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This invention employs a serpentine symmetrical arrangement of heating tubes that rotate synchronously with the shaft. This allows the high-temperature heating medium to exchange heat with the yellow phosphorus wastewater in the tank with a larger contact area during circulation. During rotation, the heating tubes can cover different areas of the tank, avoiding localized heating blind spots. Combined with the fixing components for the stable installation of the heating tubes, this ensures their stable position during rotation, further enhancing the uniformity of heating and keeping the yellow phosphorus in the wastewater in a continuously molten state, creating favorable conditions for subsequent recycling.

[0016] Furthermore, through the rotating connection design of two sets of concentric central boxes, baffle rings and inlet and outlet pipes, stable diversion and return of heating medium are achieved. Even if the central box rotates with the rotating shaft, the inlet and outlet pipes can be kept in a fixed position by the fixed frame to ensure that the medium circulation path is not affected by rotation.

[0017] In summary, this invention efficiently and uniformly heats yellow phosphorus wastewater, keeping the yellow phosphorus in a liquid state, thereby improving recovery efficiency, reducing treatment costs, and simplifying the process. Attached Figure Description

[0032] Example

[0033] like Figure 1 and Figure 2 As shown, the thickener heating mechanism proposed in this utility model includes a thickener body 1, which includes a tank 11. A crossbeam 12 is installed on the top of the thickener body 1, and a servo motor 13 is provided on the top of the crossbeam 12. The output end of the servo motor 13 passes through the crossbeam 12 and is fixedly connected to a rotating shaft 14. Multiple rake mechanisms 15 are fixedly connected to the outer ring of the rotating shaft 14. All of the above are existing technologies and will not be described in detail here.

[0034] Furthermore, the heating mechanism also includes multiple sets of heating tubes 2 disposed on the outside of the rotating shaft 14. The heating tubes 2 are arranged in a serpentine pattern and are symmetrically arranged with the rotating shaft 14 as the center. When the high-temperature liquid circulates in the heating tubes 2, it heats the wastewater in the tank 11, so that the yellow phosphorus is in a molten state.

[0035] For further details, please refer to Figure 3 and Figure 4The heating mechanism also includes multiple sets of fixing components 3. The fixing components 3 are used to fix the heating tube 2 to the side of the rotating shaft 14, so that when the rotating shaft 14 rotates, it drives the heating tube 2 to rotate synchronously, thereby improving its heating efficiency. The fixing components 3 include positioning frames 31 set on both sides of the heating tube 2. Multiple sets of fasteners 32 are connected between the two sets of positioning frames 31. The fasteners 32 are located at the bend and bottom of the heating tube 2. The positioning frames 31 are fixed to both sides of the heating tube 2 by the fasteners 32. At the same time, after the positioning frames 31 are fixed in position, the position of the heating tube 2 is limited by the fasteners 32. Two sets of positioning frames 31 are fixedly connected to a connecting plate 33 on the side near the rotating shaft 14. The two sets of connecting plates 33 are located on the side of the two sets of positioning frames 31 that are far apart. A combination plate 34 is provided on the side of the two sets of connecting plates 33 near the rotating shaft 14. Multiple sets of first screws 35 are fixedly connected to the combination plate 34. The first screws 35 pass through the connecting plate 33 and are threaded with a first nut 36. The connecting plate 33 is fixed to the side of the combination plate 34 by the first screws 35 and the first nut 36, forming a whole. This whole can be disassembled and installed for easy maintenance. The fixing assembly 3 also includes a fixing plate 37 disposed on the side of the combination plate 34 near the rotating shaft 14. The fixing plate 37 is fixedly connected to the rotating shaft 14. Multiple sets of second screws 38 are installed on the side of the fixing plate 37. The second screws 38 pass through the combination plate 34 and the connecting plate 33 and are threadedly connected to the second nut 39. The position of the fixing plate 37 is fixed. The combination plate 34 is fixed to the side of the fixing plate 37 by the second screws 38 and the second nut 39, thus completing the installation. This allows the heating tube 2 to rotate when the rotating shaft 14 rotates.

[0036] Specifically, such as Figure 3 and Figure 5As shown, the heating mechanism includes a centralizing mechanism 4 disposed at the top of multiple sets of heating tubes 2. The centralizing mechanism 4 is used for the entry and exit of the heating medium from the multiple sets of heating tubes 2. The centralizing mechanism 4 includes two concentrically arranged central boxes 41. The central boxes 41 are annular and hollow. Multiple sets of connecting pipes 42 are fixedly connected to the bottom of the central boxes 41. The connecting pipes 42 below the two sets of central boxes 41 are respectively connected to both ends of the heating tubes 2. After the heating medium enters the central boxes 41, it communicates with the multiple sets of heating tubes 2. Two sets of retaining rings 43 are provided on the top wall of the central boxes 41. Both sets of retaining rings 43 have an L-shaped cross-section. A retaining ring 44 is rotatably connected between the two sets of retaining rings 43, and the top of the central boxes 41 is sealed by the retaining ring 44 and the retaining rings 43. A rubber gasket is provided between the retaining ring 44 and the retaining ring 43 to enhance the sealing performance. An inlet / outlet pipe 45 is fixedly connected to the top of the retaining ring 44. The inlet / outlet pipe 45 is rotatably connected to the top of the collection box 41. The inlet / outlet pipe 45 can remain in its original position when the collection box 41 rotates due to the retaining ring 44. Thus, the heating medium can circulate in multiple heating tubes 2 through the inlet / outlet pipes 45 on the two sets of collection boxes 41 to heat the wastewater in the tank 11. A fixing frame 46 is fixedly connected to the bottom of the crossbeam 12. The fixing frame 46 is L-shaped. Both sets of inlet / outlet pipes 45 pass through the fixing frame 46 and are fixed therein, so that the positions of the two sets of inlet / outlet pipes 45 are fixed. Multiple sets of synchronous plates 47 are fixedly connected to the outer ring of the rotating shaft 14. Both sets of collection boxes 41 are fixedly connected to the synchronous plates 47. When the rotating shaft 14 rotates, it drives the two sets of collection boxes 41 to rotate synchronously.

[0037] Furthermore, the heating mechanism also includes a heat exchanger and a water pump. The heat exchanger and the water pump are connected to two sets of inlet and outlet pipes 45 through pipes. The water pump is used to drive the heating medium to circulate, and the heat exchanger is used to heat the heating medium after it flows to the outside of the heating pipe 2, so as to ensure that the temperature of the heating medium flowing into the heating pipe 2 is high enough to heat the wastewater in the tank 11.

[0038] In this embodiment, the water pump is first started, driving the heating medium to flow out of the heat exchanger and into the collection box 41 of the collection mechanism 4 through the inlet and outlet pipes 45. Since the connecting pipe 42 at the bottom of the collection box 41 is connected to both ends of multiple sets of heating tubes 2, the heating medium can be evenly distributed to each heating tube 2.

[0039] In the heating tubes 2, which are arranged in a serpentine pattern and symmetrically distributed around the rotating shaft 14, they rotate synchronously with the rotating shaft 14. During the rotation, the high-temperature heating medium exchanges heat fully with the yellow phosphorus wastewater in the tank 11 through the tube wall, transferring heat to the wastewater. This ensures that the yellow phosphorus in the wastewater remains in a molten state, thus creating favorable conditions for subsequent solid-liquid separation and yellow phosphorus recovery.

[0040] The positioning frame 31 cooperates with the fastener 32 to firmly clamp the heating tube 2. The connecting plate 33 and the combination plate 34 are connected into a whole by the first screw 35 and the first nut 36, and then connected to the fixing plate 37 and fixed on the rotating shaft 14 by the second screw 38 and the second nut 39, ensuring that the heating tube 2 can rotate reliably with the rotating shaft 14, effectively improving the heating efficiency and uniformity.

[0041] Two concentrically arranged central boxes 41 are sealed at the top by the cooperation of baffle rings 44 and retaining rings 43. The inlet and outlet pipes 45 are connected by the rotation of baffle rings 44, and remain in a fixed position when the central boxes 41 rotate with the rotating shaft 14, ensuring that the heating medium can flow in and out stably. After the heating medium completes heat exchange in the heating tube 2, it flows back to the central box 41 through the connecting pipe 42, and returns to the heat exchanger through the inlet and outlet pipes 45 for reheating, forming a continuous circulating heating system.

[0042] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
