Description

Technical Field

[0002] The powder collecting tube is used to collect the hot metal powder from the smelting and powder making device, which will inevitably generate a lot of waste heat. If the temperature of the collecting tube is too high, it may cause the internal conductivity of the collecting tube to fail and become ineffective. If it is not discovered in time, the equipment may be ineffective for a long time, which is not conducive to removing the ultrafine suspended metal powder produced by the fifth-generation supersonic medium-frequency induction melting atomization equipment for copper chromium zirconium (CuCrZr) powder making and screening. Summary of the invention

[0003] In view of the problems existing in the above-mentioned prior art, the present invention provides a cooling structure for a powder collecting cylinder, which can cool the powder collecting cylinder and ensure long-term stable operation of the equipment.

[0004] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a cooling structure of a powder collection cylinder, including a cooling device main frame bracket, a control panel, a powerful heat dissipation fan, an air guide plate, a cooling agent spraying device, a heat conducting plate, a water and electricity supplement interface and an inspection window, the upper part of the cooling device main frame bracket is provided with a control panel and a powerful heat dissipation fan for enhancing the heat dissipation efficiency of the heat conducting plate, two rectangular through holes of different sizes are opened on the surface of one side of the cooling device main frame bracket, and the water and electricity supplement interface and the inspection window are respectively installed for replenishing water-based coolant and power supply for the equipment, and a group of air guide plates, a group of cooling agent spraying devices and a group of heat conducting plates are respectively connected to the upper part of the cooling device main frame bracket through bearings, so that a group of air guide plates, a group of The cooling agent spray device and a group of heat conducting plates can adjust the angles according to the needs to adapt to powder collection tubes of various specifications. The control panel is respectively connected to a group of cooling agent spray devices and a group of heat conducting plates through pipes and wires; the cooling device main frame bracket is composed of a support equipment box, a water-based cooling agent storage box, a cooling agent pressurized injection pump and a cooling device angle adjustment device. The support equipment box, the water-based cooling agent storage box, the cooling agent pressurized injection pump and the cooling device angle adjustment device are respectively fixed by the bracket inside the cooling device main frame bracket. The support equipment box is respectively electrically connected to the water-based cooling agent storage box, the cooling agent pressurized injection pump, the cooling device angle adjustment device, the cooling agent spray device, the water and electricity supplement interface and the heat conducting plate, for Receive various signals collected and sent back by these devices to help the 51 single-chip computer control the equipment for fine-tuning as needed. The coolant pressurized injection pump is connected to the water-based coolant storage tank and the coolant spraying device through pipelines. The water-based coolant storage tank is connected to the water and electricity replenishment interface through pipelines. The device combination supplies water-based coolant to the equipment. The cooling device angle adjustment device is connected to a group of air guide plates, a group of coolant spraying devices and a group of heat conduction plates through bearings; the heat conduction plate is composed of an angle adjustment shaft mounting groove, a heat conduction substrate, heat dissipation capacity enhancing fins, a temperature sensor, a heat conduction substrate coupling and a heat conduction substrate radian converter. The two sides of more than two heat conduction substrates are respectively connected to each other through the heat conduction substrate coupling to form a heat dissipation system. Hot plate, this device can change the curvature to match powder collection tubes of different specifications, so that the heat sink is close to the surface of the powder collection tube to improve the heat dissipation efficiency. The two ends of the heat sink are welded to the angle adjustment shaft mounting grooves, and the upper and lower ends of the heat sink are fixedly installed with the heat conductive substrate curvature converter. Each heat conductive substrate surface is provided with more than two heat dissipation capacity enhancing fins to further enhance the heat dissipation efficiency.

Among the metal thermal conductivity, gold and silver are the materials with the best thermal conductivity, but the disadvantage is that they are too expensive and it is not realistic to be widely used. The heat dissipation effect of pure copper is second, but it is already very excellent, but the copper sheet also has its own disadvantages: high cost, heavy weight, corrosion resistance, poor plasticity, etc. In addition, the oxidizability of copper is the biggest drawback of copper itself. Once copper is oxidized, the thermal conductivity and heat dissipation will be greatly reduced. Therefore, most heat sinks are now made of light and strong aluminum materials, among which aluminum alloy has the best thermal conductivity, so the heat conducting plate is made of aluminum alloy.

[0007] To further describe the present invention, the number of thermally conductive substrates constituting the heat conductive plate is not less than eight, each thermally conductive substrate is not less than ten centimeters wide and has a certain curvature. Engineers calculated that eight pieces can maximize the number of different powder collection tubes. Too many pieces will increase the cost, and too few pieces will reduce the heat dissipation efficiency due to too few fitting surfaces.

[0008] To further describe the present invention, the heat-conducting substrate curvature converter is made of rubber with a built-in motor and a shrink wire, which drives the heat dissipation plates connected by multiple heat-conducting plates to fit the powder collection tube as closely as possible.

[0009] To further describe the present invention, the heat dissipation enhancement fins are of a multi-piece structure and have an unfolded length of no less than six centimeters, a size that can maximize heat dissipation without hindering the movement of other devices.

[0010] By means of the above scheme, the present invention has at least the following advantages: compared with conventional heat dissipation methods, the present device can ensure that the powder collecting tube will not fail due to overheating during continuous operation, and ensure that the metal powder production efficiency will not be reduced.
