Description

Technical Field

[0001] This utility model relates to the technical field of aluminum liquid processing equipment, specifically a quantitative furnace trough aluminum liquid gas jet cleaning device. Background Technology

[0002] In the processing and production process, the flow channel of a quantitative furnace is a crucial component for conveying molten aluminum. However, during operation, after the aluminum liquid is pumped out of the furnace and the probe descends to stop feeding, some molten aluminum cannot be quickly cut off. This portion of molten aluminum remains in the flow channel, forming aluminum dross and impurities. These deposits not only affect the smooth flow of the molten aluminum, reducing production efficiency and decreasing the sensitivity of the quantitative furnace probe, but may also lead to a decline in the quality of the molten aluminum, causing product defects. Currently, the cleaning of the flow channel of a quantitative furnace mainly employs two methods: manual cleaning and mechanical cleaning. Manual cleaning is labor-intensive, inefficient, and the cleaning effect is difficult to guarantee. While mechanical cleaning improves efficiency to some extent, it still has limitations in cleaning the complex internal structure of the flow channel and may also damage the inner wall of the flow channel. Therefore, developing an efficient, convenient, and effective cleaning device that can protect the flow channel is of significant practical importance. Utility Model Content

[0003] In view of this, the present invention aims to propose a gas jet cleaning device for aluminum liquid in a quantitative furnace trough, which can solve the problems of high labor intensity, low efficiency, poor cleaning effect and easy damage to the trough in the existing quantitative furnace trough cleaning methods.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A gas jet cleaning device for aluminum liquid in a quantitative furnace trough includes a gas supply system, which includes a high-pressure gas source connected to a control valve via a pipeline. Two jetting units are installed at the trough opening at the end of the trough. Each jetting unit includes a mounting base and a jetting pipe. The mounting base is installed on the outer wall of the trough, and the jetting orifice of the jetting pipe extends into the trough opening. The control system is connected to the quantitative furnace signal and is used to receive the electrical signal from the falling probe of the quantitative furnace and trigger the control valve, causing the gas from the high-pressure gas source to be sprayed onto the inner wall of the trough through the jetting pipe.

[0006] In some embodiments, two injection units are symmetrically distributed on both sides of the flow channel opening.

[0007] In some embodiments, the end of the jet pipe extending into the flow channel is provided with two inclined jet holes, the direction of which forms an impact angle with the inner wall of the flow channel.

[0008] In some embodiments, the mounting base and the flow channel are fixedly connected by bolts or welding.

[0009] In some embodiments, a sealing connection is provided between the injection pipe and the fixed base.

[0010] In some embodiments, the control valve is a control solenoid valve.

[0011] In some embodiments, the gas supplied by the high-pressure gas source is compressed air or nitrogen. Attached Figure Description

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] The following is for reference. Figures 1 to 2 The quantitative furnace trough 8 aluminum liquid gas jet cleaning device of this utility model is described in conjunction with the embodiments.

[0020] Gas Supply System: This device includes a high-pressure gas source 2, which is connected to a gas control valve via a pipeline. The high-pressure gas source 2 provides gas with sufficient pressure, preferably compressed air, nitrogen, or other inert gases, which can achieve efficient cleaning without chemically reacting with the molten aluminum and its deposits. The gas control valve controls the two injection units to inject gas, ensuring that the inlet 3 of the flow channel 8 is cleaned by blowing air, so that the flow of molten aluminum into the flow channel 8 is quickly cut off and the flow into the pressure chamber is cut off.

[0021] Injection Units: Two injection units are distributed along the left and right sides of the flow channel opening 3. Each injection unit includes a fixed base 1 installed on the outer wall of the flow channel 8 and an injection pipe 5 extending into the flow channel 8. The injection pipe 5 is provided with two injection holes at one end inside the flow channel 8. The direction and angle of the injection holes are carefully designed to allow the gas to be injected onto the inner wall of the flow channel 8 at a specific angle and range, thereby effectively impacting the residual aluminum liquid and causing it to flow into the pressure chamber along the flow channel 8.

[0022] Control system: The metering furnace outputs a signal. When the metering furnace probe falls, the furnace sends an electrical signal, automatically controlling solenoid valve 6 to trigger the gas injection system to start the cleaning operation. This achieves automated operation of the entire cleaning process.

[0023] Installation and debugging:

[0024] First, determine the installation position of the injection unit based on the structure of the metering furnace flow channel 8 and the metering furnace outlet. Securely install the fixing base 1 onto the flow channel opening 3 using bolts or welding.

[0025] Then, connect the injection pipe 5 to the fixed base 1 via the sealing connector 4, ensuring a good seal at the connection to prevent gas leakage. Connect the high-pressure gas source 2 to the solenoid valve signal line.

[0026] Finally, turn on the power supply of the control system, debug the output pressure of the high-pressure gas source 2 and the solenoid valve signal connection, and set appropriate initial parameters according to the actual situation of the flow channel 8.

[0027] Cleanup operation:

[0028] When the quantitative furnace is performing the feeding operation, after the aluminum liquid passes through the flow channel 8, the quantitative furnace sends a signal to trigger the gas injection system to start and carry out the cleaning operation. The control system controls the high-pressure gas source 2 to output gas with a certain pressure according to the preset parameters and distributes it to the two injection units.

[0029] The injection pipe 5 of the injection unit injects gas through the injection hole at a specific angle and pressure onto the inner wall of the flow channel 8. The impact force of the high-pressure gas acts on the attached aluminum slag and impurities, causing them to fall off from the inner wall of the flow channel 8, thereby cutting off the aluminum liquid in the flow channel 8.

[0030] During the cleaning process, the operator can adjust the output pressure of the high-pressure gas source 2 and the gas output of the gas distributor in real time through the control system according to the cleaning status of the flow channel 8, so as to achieve the best cleaning effect.

[0031] Maintenance and care:

[0032] Regularly check whether the pressure of high-pressure gas source 2 is normal and whether there are any leaks in the gas pipeline. If a leak is found, repair or replace the relevant parts in a timely manner.

[0033] Check if the mounting bracket 1 of the spray unit is loose and if the spray pipe 5 is damaged. If there is a problem, tighten or replace it in time.

[0034] Regularly clean impurities from the gas distributor and the inside of the injection pipe 5 to prevent blockage and affect the gas injection effect.

[0035] Regularly maintain the control valves to ensure that their control functions are normal and the parameter settings are accurate.

[0036] Compared with existing technologies, the quantitative furnace flow channel 8 aluminum liquid gas jet cleaning device of this utility model has the following advantages:

[0037] High-efficiency cleaning: Utilizing the impact force of high-pressure gas, it can quickly and effectively remove aluminum slag and impurities adhering to the inner wall of the flow channel, greatly improving cleaning efficiency. Compared with manual cleaning and traditional mechanical cleaning, the cleaning time can be greatly shortened, and cleaning can be carried out without stopping the machine.

[0038] Protecting the flow channel: The gas jet cleaning method does not cause physical damage to the inner wall of the flow channel, effectively extending the service life of the flow channel and reducing equipment replacement and maintenance costs.

[0039] Easy to operate: The cleaning process can be precisely controlled through the control system, eliminating the need for operators to perform complex operations, reducing labor intensity, and minimizing the impact of human factors on the cleaning effect.

[0040] Highly adaptable: The number, position, and gas injection parameters of the injection units can be flexibly adjusted according to the quantitative furnace flow channels of different specifications and structures, making it widely applicable.
