Description

Technical Field

[0001] This utility model relates to the field of recycling devices, specifically an industrial waste heat recovery device. Background Technology

[0002] Industrial waste heat refers to the underutilized heat generated during industrial processes such as manufacturing, power generation, chemical production, and refining. These processes typically involve energy conversion or the use of heat to perform specific operations. However, the processes do not fully utilize all the energy input; a portion is released as heat, forming waste heat. This waste heat actually contains a significant amount of energy waiting to be discovered and utilized. An industrial waste heat recovery device is a device that can collect and reuse the waste heat generated during industrial production.

[0003] However, most existing industrial waste heat recovery devices on the market currently use hot air to rise through water pipes to heat the water inside the pipes, thereby achieving heat recovery and reuse. As the hot air rises, its temperature drops, resulting in a decrease in the effectiveness of heat recovery. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an industrial waste heat recovery device that has the advantages of maintaining the temperature during heat recovery, thereby improving the heat recovery effect. It solves the problem that the heat recovery effect deteriorates because the temperature of the hot air decreases as it rises through the water pipe to heat the water inside the pipe and thus achieve heat recovery and reuse.

[0006] (II) Technical Solution

[0007] To achieve the goal of maintaining the temperature during heat recovery and thus improving the heat recovery effect, this utility model provides the following technical solution: An industrial waste heat recovery device, comprising a wastewater tank, a conveying pipe, and a purification pipe. An inlet pipe is fixedly connected to the top of the wastewater tank, and an outlet pipe is fixedly sleeved on the top of the wastewater tank. A winding rod is fixedly connected to the inner wall of the wastewater tank, and a winding tube is fixedly wound around the outer wall of the winding rod. One end of the winding tube is fixedly connected to a first connecting pipe, which is fixedly sleeved with the wastewater tank. The other end of the winding tube is fixedly connected to a second connecting pipe, which is fixedly sleeved with the wastewater tank. The second connecting pipe has a water valve on its outer wall. A winding pipe is fixedly wound around the outer wall of the winding rod. One end of the winding pipe is fixedly connected to a first connecting pipe, which is fixedly sleeved with the wastewater tank. The other end of the winding pipe is fixedly connected to a second connecting pipe, which is also fixedly sleeved with the wastewater tank. The outer wall of the second connecting pipe has a water valve. Domestic water can enter the winding pipe through the first connecting pipe and then exit from the second connecting pipe by opening the water valve. Since the wastewater is hot, the domestic water will be heated when passing through the winding pipe, thus achieving heat recovery without temperature drop and improving the heat recovery effect.

[0008] As a preferred technical solution of this utility model, the outer wall of the conveying pipe is provided with a threaded surface, and the inner wall of the purification pipe is provided with a mesh plate. Water will pass through the purification pipe before entering the wastewater tank, and then enter the purification pipe through the mesh plate. The inside of the purification pipe is filled with activated carbon, which can filter the wastewater.

[0009] As a preferred embodiment of this utility model, an installation tube is fixedly connected to one side of the purification tube, and a groove is provided on one side of the installation tube. A spring is fixedly connected to the inner wall of the groove, and a movable tube is fixedly connected to one end of the spring. The movable tube can move into the groove, thereby shortening the distance between the movable tube and the purification tube.

[0010] As a preferred technical solution of this utility model, the outer wall of the moving tube is slidably connected to the inner wall of the groove, and one end of the moving tube is fixedly connected to a bearing. Since the distance between the moving tube and the purification tube can be shortened, it is convenient to disassemble and install the purification tube.

[0011] As a preferred embodiment of this utility model, the outer ring of the bearing is fixedly connected to a rotating tube, and the inner wall of the rotating tube is provided with a threaded groove, so that the rotating tube can be rotated by the bearing.

[0012] As a preferred technical solution of this utility model, the rotating tube is threadedly connected to the threaded surface, thereby ensuring that the purification tube will not detach from the water inlet pipe and the delivery pipe.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides an industrial waste heat recovery device, which has the following beneficial effects:

[0015] 1. A winding tube is fixedly wound around the outer wall of a winding rod. One end of the winding tube is fixedly connected to a first connecting pipe, which is fixedly sleeved with a wastewater tank. The other end of the winding tube is fixedly connected to a second connecting pipe, which is also fixedly sleeved with the wastewater tank. A water valve is provided on the outer wall of the second connecting pipe. Domestic water can enter the winding tube through the first connecting pipe, and then exit from the second connecting pipe by opening the water valve. Since the wastewater is hot, the domestic water will be heated when passing through the winding tube, thus achieving heat recovery without temperature drop, thereby improving the heat recovery effect.

[0016] 2. By rotating the tube and connecting it to the threaded surface, the purification tube will not detach from the inlet and delivery tubes. The moving tube can move into the groove, thereby shortening the distance between the moving tube and the purification tube. This facilitates the disassembly and installation of the purification tube, further meeting the usage requirements of the device and providing auxiliary functions. Therefore, it is worth promoting.
