Abstract
Description
Technical Field
[0001] This utility model relates to the field of flux drying technology, and in particular to a flux drying box that provides uniform drying. Background Technology
[0002] The descriptions in this section provide background information relating to this disclosure and do not constitute prior art.
[0003] Flux is a granular welding material used to provide wettability and protection to the weld joint. It is composed of various chemical components, including resins, activators, fluxes, and flow agents. However, when flux is exposed to air or stored for an extended period, its components or additives may contain hygroscopic substances such as sodium chloride and ammonium chloride. These substances are hygroscopic and will absorb moisture from the surrounding environment. Alternatively, when the flux is exposed to a humid environment, they will absorb moisture from the surrounding environment, resulting in a certain amount of water in the flux.
[0004] During the welding process, the flux contains a certain amount of moisture. When the flux is heated, the moisture evaporates to form water vapor, which can cause defects such as porosity during the welding process and have a significant impact on the welding quality. Therefore, the flux needs to be dried before use. However, during the drying process, the flux accumulates together, making it difficult for hot air to blow evenly into the flux and making it difficult to dry the flux evenly. Summary of the Invention
[0005] The purpose of this invention is to provide a flux drying box with uniform drying. The multi-stage airflow extends the drying path, and the hot air distribution structure, combined with the inclined guide plate, ensures the material slides down while drying it. During the sliding process, the flux is dispersed due to the order of its fall, preventing it from piling up. The hot air evenly dries the dispersed flux, solving the technical problem of flux piling up in traditional flux drying boxes, which makes it difficult for hot air to blow evenly into the flux and dry it evenly.

[0011] As a further optimization, to facilitate the even distribution of material on the inclined plate, expel unconsolidated flux, and remove consolidated flux through the rectangular window, a material even distribution component is inserted into the space between the top surface of the inner cavity of the drying oven and the upper end of the inclined plate. This component includes: A long rod is inserted into the space between the top surface of the inner cavity of the drying oven body and the upper end of the inclined plate; A grating head is fixedly fitted to the end of the long rod away from the rectangular window.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a flux drying oven for uniform drying, comprising: The main body of the drying oven 1 has its feeding section located at the top and its discharging section located at the bottom. An inclined agglomerated flux screening structure 2 is installed at the upper end of the inner cavity of the drying oven body 1, with its inclined upper end located below the feed section of the drying oven body 1. The main body 1 of the drying oven is equipped with a multi-stage flux conveying and drying structure 3 in the middle of its inner cavity, and its lower output end is located above the discharge section of the main body 1 of the drying oven. The flux multi-stage conveying and drying structure 3 includes: The first inclined guide plate 31, the second inclined guide plate 32 and the third inclined guide plate 33 are fixedly assembled in the middle of the inner cavity of the drying oven body 1 from top to bottom and left to right. A hot air distribution structure 34 is installed on the outer wall of the main body 1 of the drying oven, corresponding to the upper extension direction of the first inclined guide plate 31, the second inclined guide plate 32 and the third inclined guide plate 33. A moisture discharge structure 35 is installed on the outer wall of the drying oven body 1, corresponding to the lower extension direction of the first inclined guide plate 31 and the second inclined guide plate 32.
[0024] Specifically, in this embodiment, the main body 1 of the drying oven is made of stainless steel and is specifically processed into a rectangular shape; Furthermore, an inclined agglomerated flux screening structure 2 is used to screen the flux to be dried fed into the main body of the drying chamber 1 to remove flux that has agglomerated due to moisture. During the fall of the screened flux, it is guided and conveyed by a multi-stage flux conveying and drying structure 3. The first inclined guide plate 31, the second inclined guide plate 32, and the third inclined guide plate 33 extend the drying path through three stages of flow. The hot air distribution structure 34 provides hot air to cooperate with the inclined surface of the guide plate to ensure the material slides down while drying the material. More specifically, the hot air distribution structure 34 outputs uniformly dispersed hot air. The hot air blows along the inclined surface of the guide plate, causing the screened flux to disperse during the sliding process due to the order of falling, preventing it from piling up. The hot air plays a role in uniformly drying the dispersed flux. Understandably, the moisture exhaust structure 35 is used to exhaust hot air carrying moisture, so as to avoid the moisture not being discharged in time and affecting the drying efficiency of the flux.
[0025] In some embodiments, the inclined angle of the inclined agglomerated flux screening structure 2, the first inclined guide plate 31, the second inclined guide plate 32 and the third inclined guide plate 33 is 15 degrees, so that the material can be guided and conveyed downward by the hot air in conjunction with the inclined angle of the first inclined guide plate 31, the second inclined guide plate 32 and the third inclined guide plate 33.

A mesh plate 341 is fixedly connected to the outer side of the air inlet 343, and a hot air blower 342 is fixedly assembled at its outer end. An arc-shaped cover 344 is fixedly installed at the inner edge of the inner wall of the air inlet 343, with its protrusion facing the inner side of the drying oven body 1. The outer wall of the arc-shaped cover 344 is evenly provided with exhaust vents 345.
[0027] Specifically in this embodiment, the hot air blower 342 is connected to an external power source, and the hot air blower 342 provides hot air that passes through the mesh plate 341 and the air inlet 343 into the drying oven body 1. Furthermore, the hot air passes through the exhaust vents 345 that are evenly distributed on the outer wall of the arc-shaped cover 344 and enters the main body of the drying chamber 1, so as to dry the flux to be dried more evenly with hot air. More specifically, the dispersed hot air blows along the inclined direction of the corresponding guide plate, which, while drying the material, also has the function of blowing the material down.
[0028] In some embodiments, the moisture venting structure 35 includes: The exhaust vent 353 is located on the outer wall of the drying oven body 1 at the lower extension direction of the first inclined guide plate 31 and the second inclined guide plate 32. A gas collection hood 351 is fixedly installed inside the exhaust vent 353, with its opening facing the inside of the drying oven body 1. An air extraction connection pipe 352 is fixedly connected to the middle of the outer side of the air collection hood 351.
[0029] Specifically in this embodiment, the air collecting hood 351 is used to collect the hot air with moisture blown down along the inclined direction of the guide plate, and the hot air is discharged to the outer wall of the drying oven body 1 along the exhaust connection pipe 352. Furthermore, the exhaust connection pipe 352 is connected to an external exhaust device to extract the hot air carrying moisture that blows over the first inclined guide plate 31 and the second inclined guide plate 32 and discharge it to the outside of the drying oven body 1. More specifically, the material discharged along the third inclined guide plate 33 falls above the discharge hopper 14 and is discharged from the discharge hopper 14.
[0030] In some embodiments, the inclined agglomerated flux screening structure 2 includes: Inclined plate 21 is fixedly assembled to the upper end of the inner cavity of the drying oven body 1; The top surface of the inclined plate 21 is evenly provided with discharge through holes 22; A rectangular window 24 is provided on the upper right side of the main body 1 of the drying oven, and a guide plate 23 is fixedly installed on the bottom surface of its inner cavity. The lower end of the inclined plate 21 extends to the upper surface of the guide plate 23.
[0031] Specifically in this embodiment, the inclined plate 21 uses the discharge through holes 22 evenly opened on its top surface to screen out the lumps in the lumpy material falling on it, so as to avoid affecting the use of flux. Furthermore, the sifted agglomerated material slides along the inclined plate 21 and is discharged from the rectangular window 24; More specifically, the agglomerated material that slides out along the inclined plate 21 is discharged along the guide plate 23.
[0032] In some embodiments, a material distribution member 25 is inserted into the space between the top surface of the inner cavity of the drying oven body 1 and the upper end of the inclined plate 21, which includes: Long rod 251 is inserted into the space between the top surface of the inner cavity of the drying oven body 1 and the upper end of the inclined plate 21; A puller head 252 is fixedly mounted on one end of the long rod 251 away from the rectangular window 24.
[0033] Specifically in this embodiment, the long lever 251 facilitates hand operation of the material spreading member 25. The long lever 251 controls the spreading head 252 to spread the material on the inclined plate 21 evenly, making it easier to discharge unclumped flux and to scrape out the clumped flux from the rectangular window 24.
[0034] In some embodiments, the drying oven body 1 includes: A rectangular box 11 has a feed hopper 12 fixedly connected to its top left side; A discharge hopper 14 is fixedly connected to the left side of the bottom surface of the rectangular box 11; A conical guide groove 15 is provided at the top of the inner cavity of the rectangular box 11, corresponding to the discharge hopper 14. The upper end of the feed hopper 12 is fitted with a cover plate 13.
[0035] Specifically in this embodiment, the feed hopper 12 is used for feeding materials, which are then screened, dried, and discharged along the discharge hopper 14. Furthermore, the material falling towards the upper end of the discharge hopper 14 enters the discharge hopper 14 along the conical guide channel 15, resulting in better material discharge; More specifically, the cover plate 13 shields the upper part of the feed hopper 12 to prevent dust and impurities from entering.
[0036] In some embodiments, support column structures 4 are installed at the four corners of the bottom surface of the drying oven body 1; Support column structure 4 includes: Corner code 41, which is wrapped around the four corners of the bottom surface of the main body 1 of the drying oven; Angle bracket 41 is fixedly fitted with connecting bolt 42 at the lower end of the outer wall of the drying oven body 1; Anchor 41 has a column 43 welded to its bottom surface.

More specifically, the four side columns 43 support the main body 1 of the drying box, so as to leave space for the discharge hopper 14 to discharge materials.
