Description

Technical Field

[0001] The present invention relates to the technical field of ship valve processing, in particular to a multi-process integrated processing center for ship valves. Background Art

[0002] Hull valves are key control components in ship piping systems, used to control the flow direction, pressure, flow rate, or temperature of fluids (such as seawater, fresh water, fuel oil, lubricating oil, steam, compressed air, etc.) in ship systems. They can control the flow of fluids in ship pipelines, such as oil tank top valves, fuel system, and gas tank top valves, to meet the diverse needs of ship systems. By rotating the ball or changing the position of the gate (valve plate), the flow direction of the fluid can be changed to meet the specific needs of the ship system. The pressure and flow of the fluid can be adjusted to adapt to the changing needs of the ship system. Check valves can prevent the backflow of media or fluids, thereby protecting the normal operation of pipeline equipment. On modern large passenger ships, sewage treatment equipment has become indispensable equipment. For sewage treatment equipment to function properly, various types of valves of different specifications and sizes are required to assist the sewage treatment control system.

[0003] Hull valve materials include cast iron, carbon steel, alloy steel, copper alloy, aluminum alloy, titanium alloy, stainless steel, and non-metals. They need to pass the -46°C low-temperature impact test, and the hardness of the STL alloy welded on the sealing surface must reach HRC45 or above to ensure erosion resistance at a flow rate of 6m / s. In the existing technology, a cutting device for valve production is required in the production process of valves. When processing cylindrical materials, they are cut by the cutting device. However, the existing cutting device for valve production cannot effectively clean the debris generated during the cutting of valve metal materials. Therefore, it is particularly important to improve the existing integrated processing center and design a new multi-process integrated processing center for hull valves to solve the above-mentioned technical defects and improve the practicality of the overall integrated processing center.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, through the design of the dust suction device, the dust suction device mainly includes a connecting ring, a guide cylinder, a bellows, a fixed pipe and other parts fixedly connected to the milling head of the CNC milling device. When the cylindrical material is milled, the air pump is started to generate an adsorption force inside the guide cylinder through the fixed pipe and the bellows. This adsorption force guides the waste chips and exhaust gas generated during the milling process into the interior of the fixed pipe, and then into the interior of the connecting box for treatment, effectively collecting the waste chips and exhaust gas generated during the milling process, keeping the working environment clean, improving the processing efficiency and processing quality, and avoiding the damage of waste chips to the equipment and workpiece.

[0021] 2. In the present invention, through the design of the processing component, the processing component mainly includes a connecting box, a water storage tank, a filter screen, an air pump, a guide pipe, a nozzle, a delivery pipe and other parts. The exhaust gas enters the bottom of the water storage tank through the connecting box, contacts with the filtrate inside the water storage tank for filtration, and at the same time, the water pump is started to introduce the filtrate into the interior of the nozzle through the delivery pipe to spray the exhaust gas. The treated exhaust gas is discharged through the guide fan. The filter liquid and spraying treatment effectively remove harmful substances in the exhaust gas, meet the environmental emission standards, and improve the overall practicality and environmental performance of the equipment.

[0022] 3. In the present invention, through the design of the cleaning brush, the cleaning brush is mainly connected to the movable frame through the connecting plate, sliding rod, sliding block, guide rod, second compression spring and other parts. When the movable frame is displaced, the sliding block and guide rod are driven to displace by the second compression spring, so that the connecting plate and the cleaning brush are attached to the surface of the filter screen for cleaning, effectively removing the waste debris attached to the filter screen, ensuring the filtering effect of the filter screen, and improving the stability and service life of the equipment.

[0023] 4. In the present invention, through the design of the clamping assembly, the clamping assembly mainly includes a support frame, a fixed plate, a clamping rod, a clamping block, a driving gear, a first telescopic cylinder and other parts. After the cylindrical material is placed on the top of the movable platform, the first telescopic cylinder is started to drive a group of clamping rods to rotate, and the driving gears on the outside of this group of clamping rods will drive another group of meshing driving gears to rotate, thereby causing the two groups of clamping blocks to displace and clamp the cylindrical material, thereby achieving stable clamping of the cylindrical material, preventing loosening or offset during processing, improving processing accuracy and efficiency, and ensuring processing quality.

[0024] 5. In the present invention, through the design of the closing plate, the closing plate is mainly connected to the connecting box through the moving rod, the rotating rod, the sleeve, the first compression spring and other parts. When the moving frame is displaced, the moving rod is driven to displace by the guide frame, and the moving rod then drives the rotating rod to rotate, so that the closing plate opens or closes the collection slot, realizing the automatic collection and discharge of waste chips, simplifying the operation process, and improving the degree of automation and practicality of the equipment.
