[0034] In existing high-temperature furnaces, dust in the air leads to a low yield rate of workpieces. According to the inventors' observations, this defective product mainly originates from dust accumulation inside the furnace. Inside the furnace, dust settles on the bottom wall, but as the workpiece moves along the conveyor line and is affected by the hot airflow, this deposited dust can be stirred up, adhering to the tooling and causing poor paint quality, ultimately resulting in defective products. To solve this problem, the inventors have proposed a new high-temperature furnace design.
[0035] like Figure 1-3 As shown, a high-temperature furnace is used to heat sprayed workpieces on a conveyor line.
[0036] Specifically, the high-temperature furnace includes a furnace body 100. The furnace body 100 has a heating chamber, and a conveying track 200 is provided on the bottom wall of the heating chamber. The conveying track 200 has a conveying surface for conveying tooling and workpieces fixed on the tooling.
[0037] Typically, the conveyor track 200 inside a high-temperature furnace is S-shaped. The conveyor track 200 includes multiple alternating straight segments and semi-circular arc segments at the ends of the straight segments, with the ends of two adjacent straight segments connected by the semi-circular arc segments.
[0038] The conveying track 200 has a dust collection trough 300 on at least one side, and the dust collection trough 300 is recessed into the conveying surface.
[0039] For example, the dust collection trough 300 is located between two adjacent straight segments of the conveying track 200 and extends along the extension direction of the conveying track 200.
[0040] The effective design of the dust collection tank 300 allows for timely collection of deposited dust, preventing airborne dust from being re-entrained and reducing the risk of tooling contamination. Specifically, the depth design of the dust collection tank 300 ensures that the tank walls effectively block dust from being stirred up when workpieces pass through or hot air flows, guaranteeing that the tooling is not contaminated when in contact with the workpiece.
[0041] In some embodiments, the furnace body 100 includes a plurality of alternating long base plates 400. Each long base plate 400 has a length and a width, and is generally rectangular. Furthermore, the plurality of long base plates 400 are of identical dimensions, facilitating large-scale installation within the furnace body 100.
[0042] The multiple straight segments of the conveying track 200 are respectively set in the multiple gaps between the multiple long base plates 400, so that the workpiece can move smoothly when passing through the heating chamber, reducing the flow obstruction caused by structural limitations and ensuring that the workpiece can be heated evenly.
[0043] The dust collection trough 300 is disposed on the upper surface of one of the long base plates 400.
[0044] In some embodiments, the high-temperature furnace further includes a profile frame laid on the ground, the profile frame comprising a plurality of alternately arranged profiles located on a horizontal plane at the same height on the top of the profile frame. One side of each profile has a first gap, and the other side has a second gap, the spacing of the first gap being smaller than the spacing of the second gap. The first gap forms the conveying track. The spacing of the second gap is adapted to the dimensions of the long base plate. The long base plate has edges on both sides, the width of which is adapted to the width of the profile, and the two edges respectively rest on the corresponding profiles; at least one long base plate has a recess equal to the second gap, the recess being embedded in the second gap and forming the dust collection trough 300. This design greatly facilitates daily maintenance and cleaning; workers can easily remove the long base plate 400 and periodically remove the dust from the collection trough, thereby effectively preventing dust from being stirred up again and reducing the risk of tooling contamination.
[0045] For example, the bottom of the profile rack is equipped with lockable casters, making it simple and convenient to move or adjust the position of the profile rack when needed. After unlocking the casters, the position can be easily adjusted. This flexibility not only improves maintenance efficiency but also facilitates the layout adjustment of the furnace body 100.
[0046] In some embodiments, the extension length of the dust collection trough 300 is greater than the spacing of the straight segments of the conveying track 200. This design effectively improves the dust collection capacity, allowing more dust to be captured in a timely manner and preventing it from re-entering the air. By fully utilizing the space of the bottom wall of the furnace body 100, the overall utilization efficiency is improved.
[0047] In some embodiments, the side wall of the furnace body 100 has an opening 110, the width of which is greater than the width of the long base plate 400. One of the long base plates 400 is located between the two sides of the opening 110, and the gaps on both sides of the long base plate 400 respectively form the feed inlet and discharge outlet of the conveying track 200. The dust collection trough 300 is located near the opening 110 to facilitate timely cleaning of the dust collection trough 300 after dust accumulates to a certain level. Furthermore, the thickness of the dust in the dust collection trough 300 can be directly observed through the opening 110 for timely cleaning.
[0048] In some embodiments, the dust collection trough 300 is located on a long base plate 400 between the discharge port and the feed port. This design ensures that dust is effectively captured as all workpieces passing through the furnace body 100 move, reducing the risk of dust re-entrainment. Through a reasonable layout, dust can be effectively blocked as workpieces pass through, keeping the tooling clean.
[0049] In some embodiments, the furnace body 100 is provided with a plurality of vertically arranged partitions 120. The partitions 120 are arranged alternately along the length of the furnace body 100 and divide the heating chamber of the furnace body 100 into a plurality of interconnected chambers. For example, the length of the partitions 120 is less than the width of the furnace body 100. The partitions 120 are staggered to allow the multiple chambers to connect, or windows are opened on the partitions 120 to allow the conveyor rail 200 to pass through and connect all the chambers.
[0050] The spacing between two adjacent partitions 120 is adapted to the length of the long base plate 400. Each chamber has a dust collection trough 300 on its bottom wall.
[0051] In some embodiments, the furnace body 100 further includes a hot gas source inlet pipe 510 and a waste gas outlet pipe 520. The two outlets of the hot gas source inlet pipe 510 are respectively located on both sides of the heating furnace, and the dust collection tank 300 is located between the two outlets of the hot gas source inlet pipe 510. The opening 110 of the waste gas outlet pipe 520 is located above the dust collection tank 300, allowing the waste gas generated during heating to be quickly discharged, avoiding any impact on the workpiece. Furthermore, this layout design ensures that the waste gas does not cross-contaminate with newly input hot gas, further reducing the possibility of contamination.
[0052] Similarly, each chamber is equipped with a hot gas inlet pipe and an exhaust gas outlet pipe 520. This design ensures that the hot gas can be evenly distributed to each chamber, improving heating efficiency.
[0053] In some embodiments, the two outlets of the hot gas source input pipeline are respectively located opposite each other in the width direction of the furnace body 100 and extend along the length direction of the furnace body 100.
[0054] In some embodiments, the opening 110 of the exhaust gas discharge pipe 520 is projected into the dust collection tank 300. For example, Figure 3 As shown in the figure, the opening 110 of the exhaust pipe 520 is circular, and its orthographic projection is located at the bottom of the dust collection tank. The diameter of the opening is smaller than or equal to the width of the dust collection tank. Preferably, there is at least a 2cm gap between the projection of the opening and the wall of the dust collection tank.
[0055] In this way, when dust adheres to the inner wall of the opening and falls off, it can fall directly into the dust collection tank without contaminating the tooling and workpieces on the adjacent conveyor track.
[0056] In some embodiments, the depth of the dust collection trough 300 is at least 3 cm. Examples include 3 cm, 5 cm, 8 cm, etc.
[0057] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
