Description

Technical Field

[0001] This utility model relates to the technical field of metal powder making equipment, specifically to a self-overflowing exhaust device. Background Technology

[0002] In water atomization powder production systems, the atomizing cartridge is one of the core components, and its internal pressure control directly affects process stability and powder quality. During operation, the atomizing cartridge generates a massive amount of steam instantaneously due to the intense interaction between the high-pressure water flow and molten metal, creating a continuous positive pressure inside the cartridge. If venting is obstructed, the pressure will rise rapidly, leading to seal failure and even a chain reaction of malfunctions. Therefore, timely venting of the atomizing cartridge is crucial to ensure the normal operation of the entire system.

[0003] Currently, atomizing cartridges typically employ either "open exhaust" or "one-way valve" exhaust methods. However, both methods have some shortcomings. Open exhaust directly connects the cartridge cavity to the outside environment, resulting in rapid exhaust, but it lacks backflow prevention, allowing external air to easily enter the cavity, thus disturbing the atomization flow field and disrupting process stability. While one-way valves can prevent backflow, under conditions of slight negative pressure or drastic pressure fluctuations, the valve seal is prone to loosening, and the response is relatively slow. Furthermore, most existing atomizing cartridge exhaust devices lack real-time monitoring and adjustment functions, making it impossible to visually observe the exhaust status, affecting equipment controllability and maintenance convenience. Therefore, this application aims to provide a self-overflowing exhaust device for atomizing cartridges in water atomization powder production equipment. Utility Model Content

[0004] The purpose of this invention is to address at least one deficiency of the existing technology by providing a self-overflowing exhaust device that can be used to solve the exhaust problem of the atomizing cylinder in water atomizing powder making equipment.

[0005] The technical solution of this utility model is: a self-overflowing exhaust device, including an exhaust cylinder and an exhaust pipe; an exhaust cover is provided at the upper end of the exhaust cylinder, and the inner cavity of the exhaust cylinder is directly connected to the outside through the exhaust cover; a valve is provided at the lower end of the exhaust cylinder, and the valve controls the communication state between the inner cavity of the exhaust cylinder and the outside; the exhaust cylinder can be used to store liquid; the exhaust pipe penetrates the side wall of the exhaust cylinder, the outlet of the exhaust pipe is located in the inner cavity of the exhaust cylinder, and the inlet of the exhaust pipe is located on the outside of the exhaust cylinder; and the opening of the outlet of the exhaust pipe faces downward.

[0006] Furthermore, the lower end of the exhaust pipe has an inverted conical bottom, and the valve is located at the tip of the inverted conical shape.

[0007] Furthermore, a micro-pressure gauge is installed on the exhaust pipe to measure the air pressure inside the pipe.

[0008] Furthermore, an observation window is provided on the side wall of the exhaust pipe, which is used to directly observe the situation inside the cavity of the exhaust pipe.

[0009] Furthermore, the observation window is positioned to correspond to the exhaust outlet of the exhaust pipe, so as to focus on observing the situation at the exhaust outlet.

[0010] Furthermore, the observation window also includes an air blowing mechanism for blowing on the inner surface of the glass of the observation window.

[0011] Furthermore, the air blowing mechanism includes an air blowing pipe and a speed control connector. One end of the air blowing pipe is located inside the exhaust cylinder and corresponds to the inner surface of the observation window glass; the other end of the air blowing pipe is located outside the exhaust cylinder and is connected to the speed control connector; the speed control connector is used to connect compressed air.

[0012] Furthermore, the exhaust outlet of the exhaust pipe is located above the bottom of the inverted cone. This facilitates the placement of the observation window, as the observation window must correspond to the exhaust outlet; placing the observation window in the main body of the exhaust pipe is simpler than placing it at the bottom of the inverted cone.

[0013] Furthermore, the air inlet of the exhaust pipe also faces downwards, making the entire exhaust pipe in an inverted U-shape. Preferably, the exhaust pipe is made of a transparent material to facilitate observation of the internal conditions.

[0014] Furthermore, the valve is a manual ball valve, which allows workers to operate it quickly.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The self-overflowing exhaust device in this utility model can be connected to the inner cavity of the atomizing cylinder of the water atomizing powder making equipment through an exhaust pipe; when the atomizing cylinder is working, it will generate positive pressure, at which time the gas can be quickly discharged through the self-overflowing exhaust device, thereby maintaining the gas pressure balance inside the cylinder; and the exhaust device can also effectively prevent gas backflow. An observation window is provided to observe the condition inside the exhaust cylinder in a timely manner and adjust the water level inside the exhaust cylinder accordingly; the observation window also includes a blowing mechanism, which can be used to clean the inner surface of the observation window glass when it is contaminated.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to specific embodiments. Methods or functional components not specifically described in the embodiments are all prior art. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Example

[0018] like Figure 1-2 As shown, this embodiment is a self-overflowing venting device, including an venting cylinder 1 and an venting pipe 5. The upper end of the venting cylinder 1 is provided with an venting cap 2, and the inner cavity of the venting cylinder 1 is directly connected to the outside through the venting cap 2. The lower end of the venting cylinder 1 is an inverted conical bottom 3, and a valve 4 is provided at the tip of the conical bottom 3 to control the connection between the inner cavity of the venting cylinder 1 and the outside. The venting cylinder 1 can be used to store water. The venting pipe 5 penetrates the side wall of the venting cylinder 1, and the outlet 51 of the venting pipe 5 is located in the inner cavity of the venting cylinder 1, ensuring that the outlet 51 is located above the inverted conical bottom 3, and the opening of the outlet 51 faces downwards. The inlet 52 of the venting pipe 5 is located on the outside of the venting cylinder 1, and the inlet 52 of the venting pipe 5 also faces downwards, making the entire venting pipe 5 inverted U-shape.

[0019] In this embodiment, an observation window 7 is provided on the side wall of the exhaust cylinder 1. The observation window 7 is used to directly observe the situation inside the cavity of the exhaust cylinder 1. The position of the observation window 7 corresponds to the air outlet 51 of the exhaust pipe 5, so as to focus on observing the situation at the air outlet 51.

[0020] In this embodiment, the observation window 7 further includes an air blowing mechanism 8, which is used to blow clean the inner surface of the glass of the observation window 7. The air blowing mechanism 8 includes an air blowing pipe and a speed control connector. One end of the air blowing pipe is located inside the exhaust cylinder 1 and corresponds to the inner surface of the glass of the observation window 7; the other end of the air blowing pipe is located outside the exhaust cylinder 1 and is connected to the speed control connector; the speed control connector is used to connect compressed air.

[0021] In this embodiment, a micro pressure gauge 6 for measuring the air pressure inside the exhaust pipe 5 is installed on the exhaust pipe 5. The valve 4 on the conical bottom 3 is a manual ball valve, which is convenient for workers to operate quickly.

[0022] The working process and principle of the self-overflowing exhaust device in this embodiment are as follows: The air inlet 52 of the exhaust pipe 5 is connected to the atomizing chamber, the valve 4 on the inverted conical bottom 3 is closed, and water is sent into the exhaust cylinder 1 so that the water level submerges the air outlet 51 of the exhaust pipe 5 to a certain height. When the water atomizing powder making equipment is working, positive pressure is generated in its atomizing cylinder. After the gas in the atomizing cylinder enters the exhaust pipe 5, it enters the cylinder body from the air outlet 51 and is discharged from the exhaust cover 2. When the atomizing cylinder is at normal pressure or slightly negative pressure, since the water level in the exhaust cylinder 1 is above the air outlet 51, the water in the exhaust cylinder 1 will enter the exhaust pipe 5 through the air outlet 51 first, so as to prevent the gas in the exhaust cylinder 1 from entering the exhaust pipe 5 through the air outlet 51 and then flowing back into the atomizing cylinder. At the same time, the exhaust device in this embodiment is also equipped with an observation window 7, which can observe the water level in the exhaust cylinder 1 in time. If the water level is found to be too high, the valve 4 can be opened directly to drain the water. Conversely, water can be sent into the exhaust cylinder 1 through the exhaust cover 2. Furthermore, the observation window 7 also includes an air blowing mechanism 8, which can be used to clean the inner surface of the glass of the observation window 7 when it is contaminated. In addition, the self-overflowing exhaust device in this embodiment is equipped with a micro pressure gauge 6 on the exhaust pipe 5, which can detect the working air pressure inside the device at any time.

[0023] The above are only some embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various combinations and modifications of the aforementioned technical features. Any improvements, modifications, equivalent substitutions, or applications of the structure or method of the present utility model to other fields to achieve the same effect without departing from the spirit and scope of the present utility model shall fall within the protection scope of the present utility model.
