Description

Technical Field

[0001] This utility model relates to the field of waste removal technology, specifically to a liquid storage tank welding base fixture for removing welding residues by blowing air. Background Technology

[0002] The receiver-drier is a crucial component of an air conditioning system, primarily installed at the compressor's suction end. Its core function is to prevent liquid refrigerant from flowing into the compressor, thus avoiding damage caused by liquid slugging. During air conditioning system operation, the refrigerant exiting the evaporator may not be completely vaporized. The receiver-drier separates the liquid refrigerant into gas and liquid components, storing the liquid refrigerant at the bottom of the tank while the vaporized refrigerant enters the compressor through the outlet, ensuring the compressor's safe operation. Furthermore, the receiver-drier also functions to filter impurities, buffer pressure pulsations, and recover lubricating oil.

[0003] A liquid receiver typically consists of components such as a pipe body, upper cover, lower cover, straight pipes, curved pipes, a separator plate, and a filter screen. The pipe body is the main part of the receiver, used to hold the refrigerant; the upper and lower covers seal both ends of the pipe body; the straight and curved pipes connect to other components in the air conditioning system, allowing refrigerant flow; the separator plate separates the refrigerant from the liquid, ensuring that the liquid refrigerant settles at the bottom; and the filter screen filters impurities from the refrigerant, preventing them from entering the compressor. This structural design enables the receiver to efficiently perform functions such as gas-liquid separation, impurity filtration, and lubricant recovery.

[0004] Currently, welding is commonly used to connect the various components of liquid receivers during manufacturing. However, welding generates welding waste, which remains inside the tank, causing internal contamination. This welding residue not only affects the performance and reliability of the liquid receiver but also reduces its yield rate.

[0005] To address the aforementioned issues, a liquid reservoir welding base fixture is proposed, which uses air blowing to remove welding residues. This fixture supports the liquid reservoir tube for welding to the upper or lower cover, while also helping to remove welding residues from the welding process, thereby improving the yield and reliability of the liquid reservoir. Summary of the Invention

[0006] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a liquid storage tank welding base fixture for blowing out welding residues. It is highly functional and can support the pipe body of the liquid storage tank so that it can be welded to the upper or lower cover. At the same time, it can also help to clean the welding residues during the welding process, thereby improving the yield and reliability of the liquid storage tank.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A welding base fixture for a liquid reservoir for removing welding residue by blowing air includes a mounting base. The upper end face of the mounting base has a groove, and the lower end of the groove has a sliding groove communicating with the groove. The longitudinal section of the sliding groove is crescent-shaped. The sliding groove has a waste port and multiple air blowing ports. The waste port is located at the center of the sliding groove, and the multiple air blowing ports are distributed in a ring array around the periphery of the waste port.

[0009] Furthermore, a waste channel is provided inside the mounting base, one end of which is connected to the waste outlet, and the other end of which is connected to the outside.

[0010] Furthermore, the liquid reservoir welding base fixture for removing welding residue by blowing air also includes a first blowing device located on one side of the mounting base. The mounting base has multiple air passages, the upper end of which is connected to the corresponding air inlet, and the lower end of which is connected to the first blowing device.

[0011] Furthermore, the ventilation channel gradually approaches the axis of the slide groove from top to bottom.

[0012] Furthermore, the mounting base has multiple mounting channels that extend laterally through the base along the diameter direction. The lower ends of two air channels located on the same plane are connected to the side of the corresponding mounting channel. At least one of the mounting channels is connected to the first air blowing device at its end, and the ends of the remaining mounting channels are provided with threaded holes.

[0013] Furthermore, the diameter of the ventilation channel is smaller than the diameter of the installation channel.

[0014] Furthermore, the waste channel is located above the installation channel.

[0015] Furthermore, the liquid reservoir welding base fixture for blowing away welding residues also includes a second blowing device located on one side of the mounting base, with the air outlet of the second blowing device located on the upper end face of the mounting base.

[0016] Furthermore, the surface of the mounting base is provided with a TD coating.

[0017] The beneficial effects of this utility model are as follows: The liquid storage tank welding base fixture for removing welding residue by blowing air has a simple structure and is easy to use. Air is blown into the inner wall of the liquid storage tank tube through the air blowing port, forming a turbulent flow field. The welding residue attached to the inner wall of the tube is blown off and enters the slide groove through the groove. The longitudinal section of the slide groove is crescent-shaped. The welding residue is blown by the airflow and slides along the inner wall of the slide groove towards the waste port. The airflow carries the welding residue into the waste port, thus achieving the removal of welding residue. The operation is simple. This utility model has strong functionality. It can support the liquid storage tank tube so that it can be welded to the upper or lower cover. At the same time, it can also help clean the welding residue residue during the welding process, thereby improving the yield and reliability of the liquid storage tank. Attached Figure Description

[0023] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0024] like Figure 1-3 As shown, a welding base fixture for a liquid reservoir for removing welding residue by blowing air includes a mounting base 1. The upper end face of the mounting base 1 has a groove 2, and the lower end of the groove 2 has a sliding groove 3 communicating with the groove 2. The longitudinal section of the sliding groove 3 is crescent-shaped. The sliding groove 3 has a waste port 31 and a plurality of air blowing ports 32. The waste port 31 is located at the center of the sliding groove 3, and the plurality of air blowing ports 32 are distributed in a ring array along the periphery of the waste port 31.

[0025] This utility model relates to a welding base fixture for a liquid reservoir that removes welding residue by blowing air. It has a simple structure. In use, the reservoir tube is placed on the upper surface of the mounting base 1. The opening at the lower end of the reservoir tube covers the groove 2. The upper end of the reservoir tube is welded to the upper or lower cover. During welding, molten metal droplets from the flux, tube, and upper or lower cover splash onto the inner wall of the tube. After cooling, these droplets form solid welding residue. At this time, air is blown through the air outlet 32 ​​onto the inner wall of the tube, creating a turbulent flow field that adheres to the residue. Welding residue on the inner wall of the container is blown off and enters the chute 3 through the groove 2. The longitudinal section of the chute 3 is crescent-shaped. The welding residue is blown by the airflow and slides along the inner wall of the chute 3 toward the waste port 31. The airflow carries the welding residue into the waste port 31, thus achieving the removal of welding residue. The operation is simple and the utility model is highly functional. It can support the tube of the liquid reservoir so that it can be welded to the upper or lower cover. At the same time, it can also help clean the welding residue residue during the welding process, thereby improving the yield and reliability of the liquid reservoir.

[0026] In this embodiment, the diameter of the air blowing port 32 is smaller than the diameter of the waste port 31 to prevent welding residue from clogging the air blowing port 32.

[0027] Furthermore, a waste channel 4 is provided within the mounting base 1. One end of the waste channel 4 communicates with the waste outlet 31, and the other end of the waste channel 4 communicates with the outside, resulting in a simple structure. In this embodiment, the waste channel 4 includes a vertical channel and a horizontal channel communicating with the vertical channel. The other end of the vertical channel, away from the horizontal channel, communicates with the waste outlet 31, facilitating the collection of waste materials that allow welding residues to flow to the outside.

[0028] Furthermore, the liquid reservoir welding base fixture for removing welding residues by blowing air also includes a first air blowing device located on one side of the mounting base 1. The mounting base 1 has multiple ventilation channels 5, the upper end of each ventilation channel 5 communicating with a corresponding air blowing port 32, and the lower end of each ventilation channel 5 connected to the first air blowing device. The airflow from the first air blowing device sequentially enters the slide groove 3 through the ventilation channels 5 and the air blowing ports 32, resulting in a simple structure.

[0029] Furthermore, the ventilation channel 5 gradually approaches the axis of the slide groove 3 from top to bottom, that is, the ventilation channel 5 is inclined, so that multiple ventilation channels 5 form a funnel-shaped structure, which reduces the axial resistance of the airflow and reduces energy consumption.

[0030] Furthermore, the mounting base 1 has multiple mounting channels 6 extending laterally through the base along its diameter. These mounting channels 6 intersect at the center of the mounting base 1. The lower ends of two ventilation channels 5 located on the same plane are connected to the side of their corresponding mounting channels 6. At least one mounting channel 6 has its end connected to the first air blowing device, while the ends of the remaining mounting channels 6 are provided with threaded holes 61. These threaded holes 61 are used to install the mounting base 1 inside the resistance welding machine. In this embodiment, the axis of the mounting base 1 coincides with the axis of the slide 3. There are two mounting channels 6. One mounting channel 6 has a threaded hole 61 at one end and is connected to the first air blowing device at the other end. The other mounting channel 6 has threaded holes 61 at both ends.

[0031] Furthermore, the diameter of the ventilation channel 5 is smaller than the diameter of the installation channel 6. That is, the ventilation channel 5 has been narrowed. Air is accelerated into the installation channel 6 by the first air blowing device, and then the narrowing of the ventilation channel 5 further increases the speed, resulting in strong functionality and stable operation.

[0032] Furthermore, the waste channel 4 is located above the installation channel 6, and its structure is simple.

[0033] Furthermore, the liquid reservoir welding base fixture for removing welding residues by blowing air also includes a second air blowing device located on one side of the mounting base 1. The air outlet of the second air blowing device is located on the upper end face of the mounting base 1. In use, the opening at the lower end of the liquid reservoir tube covers the groove opening of the groove 2. When the airflow from the air outlet blows off the welding residues, a small portion of the welding residues will fall onto the upper end face of the mounting base 1. After the upper end of the liquid reservoir tube is welded to the upper or lower cover, the first air blowing device is closed or the airflow rate of the first air blowing device is reduced, and the second air blowing device is opened to blow the welding residues remaining on the upper end face of the mounting base 1 into the groove 2 and into the waste inlet 31 through the slide 3. The operation is stable.

[0034] Furthermore, the surface of the mounting base 1 is provided with a TD coating, that is, the upper end surface of the mounting base 1, the groove wall of the groove 1 and the groove wall of the slide 3 are provided with a TD coating, which gives the surface of the base fixture extremely high hardness, excellent wear resistance, and the ability to resist wear and extend the service life of the base fixture.

[0035] Specifically, the TD processing flow is as follows:

[0036] 1. Cleaning

[0037] Before TD treatment, the oil, dust and oxides on the surface of the base fixture must be removed to ensure that the surface is clean so that the TD coating can be fully absorbed onto the surface of the base fixture.

[0038] 2. Drying

[0039] The base fixture needs to be dried after cleaning to ensure that the surface is dry, and to avoid the damp surface affecting the adhesion of the paint;

[0040] 3. Coating

[0041] The coating is applied evenly to the surface of the base fixture by spraying or dipping. TD coating has excellent flow properties and can quickly fill the pores and micro-unevenness of the base fixture surface to form a thin and uniform coating.

[0042] 4. Curing

[0043] The coated base fixture is placed in a curing oven for heating. The curing time and temperature depend on the type and thickness of the coating, so that a TD coating is formed on the surface of the base fixture, that is, a TD coating is formed on the surface of the mounting base.

[0044] 5. Grinding and polishing

[0045] The surface of the cured base fixture has some defects, so as to grind and polish it to make the surface smooth and clean, in order to further enhance the hardness and wear resistance of the coating.

[0046] 6. Finally, check

[0047] The coating is inspected to ensure that its density, quality, and performance meet the requirements.

[0048] In step 3, the TD coating used is an existing TD coating.

[0049] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
