Description

Technical Field

[0001] This utility model is a distillation and separation device for steel-based alloy powder waste liquid, belonging to the technical field of distillation and separation equipment. Background Technology

[0002] Traditionally, wastewater containing heavy metal ions and organic solvents is often directly discharged into the environment, causing serious pollution problems and wasting valuable metal resources. To address this challenge, distillation separation has been introduced as an effective physicochemical method into the field of wastewater treatment. Steel-based alloy powder wastewater distillation separation equipment is one such method, used to recover useful components from wastewater containing metal powders and to remove or concentrate harmful substances. These devices are commonly used in industries such as metal processing, electroplating, and electronics manufacturing, and are particularly important when processes involving liquid media such as cutting fluids, cleaning agents, and electrolytes generate large amounts of wastewater containing heavy metal ions and organic solvents. Through distillation separation technology, these wastewaters can be effectively treated, reducing environmental pollution while recovering valuable metal materials and solvents.

[0003] However, in the existing technology, the distillation of steel-based alloy powder waste liquid only uses heating equipment to separate it, which is inefficient. There is an urgent need for a steel-based alloy powder waste liquid distillation and separation device to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a distillation and separation device for steel-based alloy powder waste liquid, thereby solving the problems mentioned in the background section. This invention employs a combined structure of filtration, stirring, and heating distillation, which enables efficient distillation and separation of steel-based alloy powder waste liquid.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a steel-based alloy powder waste liquid distillation and separation device, comprising a distillation tank and a condenser. A waste liquid inlet pipe is installed through the upper left side of the distillation tank, and a filter element is inserted into the waste liquid inlet pipe. A first filter plate and a second filter plate are horizontally fixed inside the filter element. A spiral heating wire is provided on the annular side of the distillation tank, and a ceramic heating rod is provided at the lower end of the distillation tank. A stirring motor is installed at the upper end of the distillation tank, and a stirring shaft is longitudinally arranged inside the distillation tank, with the upper end of the stirring shaft being drivenly connected to the stirring motor. Multiple sets of high-strength aluminum alloy blades are installed on the annular side of the stirring shaft, and a rectangular stirring blade is longitudinally fixed at the lower end of the lowest set of high-strength aluminum alloy blades. A distillation discharge pipe is connected to the upper right side of the distillation tank. The condenser is located on the right side of the distillation tank, and the other end of the distillation discharge pipe is inserted into the condenser. The upper and lower ends of the condenser are divided into a cooling liquid chamber and a liquid storage chamber by a partition plate. A fine filter screen is horizontally fixed in the liquid storage chamber.

[0006] Furthermore, an external threaded ring is fixed at the upper end of the waste liquid inlet pipe, and a threaded sealing cap is screwed onto the external threaded ring.

[0007] Furthermore, the spiral heating wire and the ceramic heating rod are provided with an insulating cover.

[0008] Furthermore, the heat-insulating outer cover is connected to the front end of the distillation tank via bolts and sealing plates, and a maintenance door, a temperature controller, and a pressure gauge are installed thereon. The detection ends of the temperature controller and the pressure gauge are both located inside the distillation tank.

[0009] Furthermore, a drain pipe and valve are installed at the lower end of the condenser.

[0010] Furthermore, the discharge end of the distillation discharge pipe passes through the coolant chamber and is located in the liquid storage chamber, which is sealed and filled with coolant.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a distillation and separation device for steel-based alloy powder waste liquid. Because this utility model adds a filter element, a first filter plate, a second filter plate, a spiral heating wire, a ceramic heating rod, a stirring motor, a stirring shaft, high-strength aluminum alloy blades, a rectangular stirring plate, a distillation discharge pipe, and a condenser, our design improvements and actual use have shown that this device has a reasonable structure. It adopts a combined structure of filtration, stirring, and heating distillation, which can achieve efficient distillation and separation of steel-based alloy powder waste liquid. Stirring ensures that the components in the steel-based alloy powder waste liquid are fully mixed, preventing particles from settling to the bottom of the container and forming a difficult-to-remove sediment layer. This ensures a more uniform temperature distribution inside the liquid, avoiding local overheating or uneven cooling, and helps to accelerate the evaporation rate and reduce the formation of unevaporated residues. Furthermore, stirring enhances the mass exchange between the liquid and vapor interfaces, accelerating the transfer of solvents and other low-boiling-point components from the liquid phase of the steel-based alloy powder to the gas phase, thereby improving separation efficiency.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a steel-based alloy powder waste liquid distillation and separation device, including a distillation tank 1 and a condenser 19. A waste liquid inlet pipe 2 is installed through the upper left side of the distillation tank 1. A filter element 5 is inserted into the waste liquid inlet pipe 2. A first filter plate 6 and a second filter plate 7 are horizontally fixed inside the filter element 5. A spiral heating wire 8 is provided on the annular side of the distillation tank 1. A ceramic heating rod 10 is provided at the lower end of the distillation tank 1. A stirring motor 14 is installed at the upper end of the distillation tank 1. A stirring shaft 15 is arranged longitudinally inside the distillation tank 1, and the upper end of the stirring shaft 15 is connected to the stirring motor 14. The annular side of the stirring shaft 15... Multiple sets of high-strength aluminum alloy blades 16 are installed on the surface. The lower end of the lowest set of high-strength aluminum alloy blades 16 is longitudinally fixed with rectangular stirring blades 17. A distillation discharge pipe 18 is installed on the upper right side of the distillation tank 1. The condenser 19 is located on the right side of the distillation tank 1, and the other end of the distillation discharge pipe 18 is inserted into the condenser 19. The upper and lower ends of the condenser 19 are divided into a cooling liquid chamber 20 and a liquid storage chamber 22 by a partition plate. A fine filter screen 21 is horizontally fixed in the liquid storage chamber 22. This design solves the problem of low efficiency in the existing technology of distilling steel-based alloy powder waste liquid by only using heating equipment to heat and separate it.

[0019] In the first embodiment of this utility model: an outer threaded ring 3 is fixed to the upper end of the waste liquid inlet pipe 2, and a threaded sealing cap 4 is screwed onto the outer threaded ring 3. The added threaded sealing cap 4 can be screwed onto the upper end of the outer threaded ring 3, thereby blocking the waste liquid inlet pipe 2. A heat-insulating cover 9 is provided on the outside of the spiral heating wire 8 and the ceramic heating rod 10. The added heat-insulating cover 9 can prevent the heat from the spiral heating wire 8 and the ceramic heating rod 10 from easily dissipating to the outside.

[0020] The insulation cover 9 and the front end of the distillation tank 1 are connected by bolts and sealing plates to a maintenance door 11, a temperature controller 12 and a pressure gauge 13. The detection ends of the temperature controller 12 and the pressure gauge 13 are both located inside the distillation tank 1. The added maintenance door 11 makes it easy to open the insulation cover 9 and the distillation tank 1 for maintenance. The temperature controller 12 and the pressure gauge 13 facilitate the inspection of the temperature and pressure inside the distillation tank 1.

[0021] The lower end of the condenser 19 is equipped with a drain pipe 23 and a valve. The discharge end of the distillation discharge pipe 18 passes through the coolant chamber 20 and is located in the liquid storage chamber 22. The coolant chamber 20 is sealed and filled with coolant. By adding coolant to the coolant chamber 20, the distillation discharge pipe 18 located in the coolant chamber 20 can be cooled and condensed, ensuring that the gas discharged from the discharge end of the distillation discharge pipe 18 can be condensed into liquid and stored in the liquid storage chamber 22.

[0022] As a second embodiment of this utility model: First, waste liquid containing steel-based alloy powder is added into the distillation tank 1 through the waste liquid inlet pipe 2. During this process, the filter element 5, the first filter plate 6, and the second filter plate 7 can filter the steel-based alloy powder in the waste liquid multiple times. Then, the threaded sealing cap 4 is screwed onto the upper end of the outer threaded ring 3. Next, the spiral heating wire 8 and the ceramic heating rod 10 are energized, which will heat the distillation tank 1, thereby heating and distilling the steel-based alloy powder waste liquid inside. At the same time, the stirring motor 14 is started, which drives the stirring shaft 15 to rotate. The stirring shaft 15 will drive multiple sets of high-strength aluminum alloy blades 16 and multiple rectangular stirring plates 17 to rotate, thereby rotating and uniformly heating the heated steel-based alloy powder waste liquid inside the distillation tank 1. During this process, stirring can make the steel-based alloy powder... The components in the alloy powder waste liquid are thoroughly mixed to prevent particles in the steel-based alloy powder waste liquid from settling to the bottom of the distillation tank 1 and forming a difficult-to-remove sediment layer. This ensures a more uniform temperature distribution inside the liquid, avoids local overheating or uneven cooling, helps to accelerate the evaporation rate of the steel-based alloy powder waste liquid, and reduces the formation of unevaporated residues. Stirring also enhances the exchange of matter between the liquid and vapor interfaces, accelerating the transfer of solvents and other low-boiling-point components from the liquid phase to the gas phase of the steel-based alloy powder, thereby improving separation efficiency. Then, the distilled gas is discharged through the distillation outlet pipe 18 to the condenser 19 for storage. The distillation outlet pipe 18 is cooled and condensed by passing through the cooling liquid chamber 20 filled with coolant, ensuring that the gas discharged from the outlet end of the distillation outlet pipe 18 can be condensed into liquid and stored in the liquid temporary storage chamber 22.
