Vacuum uniform drying device

Abstract

This utility model relates to the field of drying equipment technology, and in particular to a vacuum uniform drying device, including a vacuum chamber. The vacuum chamber is a hollow rectangular shell structure. A suction pipe with multiple air inlets and one air outlet is located at the top of the vacuum chamber. The multiple air inlets are evenly distributed at the top of the vacuum chamber, and each air inlet communicates with the interior of the vacuum chamber. Multiple layers of flow dividers are stacked inside the vacuum chamber. The air inlets adopt a one-to-four distribution structure, dividing the entire chamber into four evenly distributed vacuum chambers. All connections between pipes use specially designed elbows to ensure that the distance from the main suction port to the four flow dividers is consistent, thereby guaranteeing the uniformity of the suction flow rate. Simultaneously, the vacuum chamber contains multiple layers of detachable flow dividers. By adjusting the thickness of the flow dividers, the distribution of the holes, and the number of layers, the uniformity of internal suction can be achieved.

Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a vacuum uniform drying device. Background Technology

[0002] The vacuum chamber has only one vacuum extraction port. When the product is dried inside the vacuum chamber, the drying time of the parts will vary. The parts closer to the vacuum extraction port will dry faster, while the parts farther away from the vacuum extraction port will dry slower, which will affect the overall structural performance of the product.

[0003] Currently, existing vacuum chambers have only one main vacuum extraction port, which directly draws vacuum from the product, making it impossible to control the uniformity of the drying effect. With only one vacuum extraction port, the drying time for parts varies during the drying process inside the chamber; parts closer to the vacuum extraction port dry faster, while those farther away dry more slowly, thus affecting the overall structural performance of the product. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum uniform drying device to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A vacuum uniform drying device includes a vacuum chamber, which is a hollow rectangular shell structure. The top of the vacuum chamber is provided with a suction pipe, multiple air inlets and an air outlet. The multiple air inlets are evenly distributed on the top of the vacuum chamber, and each air inlet is connected to the interior of the vacuum chamber. The interior of the vacuum chamber is stacked with multiple layers of flow dividers.

[0007] By adopting the above technical solution, the air inlet (exhaust port) uses a one-to-four distribution structure, dividing the entire cavity into four evenly distributed vacuum chambers. All connections between pipes use specially designed elbows to ensure that the distance from the main exhaust port to the four distribution ports is consistent, thereby guaranteeing uniform airflow velocity. Simultaneously, the vacuum chamber contains multiple layers of removable flow dividers. By adjusting the thickness of the flow dividers, the distribution of holes, and the number of layers, the uniformity of internal air extraction can be achieved, making it suitable for the rapid and uniform drying of different types and specifications of products.

[0008] In a further embodiment, the bottom of the vacuum chamber is completely open, the flow divider includes a frame, a first sealing ring and a filter plate, the filter plate is provided with densely packed powder filter holes, the inner wall of the frame is provided with a receiving groove, the first sealing ring is sleeved on the filter plate, and the filter plate is fixedly installed inside the frame.

[0009] By adopting the above technical solution, to be precise, the frame is a rectangular frame, and the inner top and inner bottom of the frame are provided with concentric extensions. The extensions are used to cover the periphery of the filter plate, and then the first sealing ring is used to seal the contact surface between the periphery of the filter plate and the inner wall of the frame.

[0010] In a further embodiment, the top periphery and the bottom periphery of the filter plate are both provided with grooves, and a second sealing ring is provided in the groove.

[0011] By adopting the above technical solution, more precisely, the frame is a rectangular frame with a concentric extension at the bottom inner side. During installation, a second sealing ring with a rectangular frame structure is first placed on the extension. Then, the filter plate with the first sealing ring on its periphery is placed inside the frame from top to bottom, so that the second sealing ring is fully inserted into the groove. Then, a second sealing ring with a rectangular frame structure is also placed in the groove at the top of the filter plate. Finally, a rectangular piece is welded to the top inner side of the frame, so that the rectangular piece constitutes the extension of the top inner side of the frame.

[0012] In a further embodiment, each splitter plate has a threaded hole on its outer periphery, and the vacuum chamber has a through hole corresponding to the threaded hole.

[0013] By adopting the above technical solution, bolts are locked into the threaded holes, and the position of the bolts is adjusted, so as to adjust the position of the filter plate inside the diverter plate. The end of the bolt located inside the frame only needs to be in contact with the periphery of the filter plate.

[0014] In a further embodiment, a mounting hole is provided at the top inner part of the vacuum chamber, and a vacuum pressure gauge is fixedly installed in the mounting hole.

[0015] The above technical solution is used to detect the vacuum level inside a vacuum chamber.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. The air inlet (exhaust port) adopts a one-to-four distribution structure, dividing the entire cavity into four evenly distributed vacuum chambers. All connections between pipes use specially designed elbows to ensure that the distance from the main exhaust port to the four distribution ports is consistent, thereby guaranteeing uniform airflow velocity. Simultaneously, the vacuum chamber contains multiple layers of removable flow dividers. By adjusting the thickness of the flow dividers, the distribution of holes, and the number of layers, consistent internal airflow can be achieved, making it suitable for the rapid and uniform drying of different types and specifications of products.

[0024] Example 1:

[0025] like Figures 1-3As shown, a vacuum uniform drying device includes a vacuum chamber 1, which is a hollow rectangular shell structure. A suction pipe 2 is provided at the top of the vacuum chamber 1, with multiple air inlets and one air outlet. The multiple air inlets are evenly distributed at the top of the vacuum chamber 1, and each air inlet communicates with the interior of the vacuum chamber 1. Multiple layers of flow dividers 3 are stacked inside the vacuum chamber 1, and the distance between each air inlet and the air outlet is consistent. The bottom of the vacuum chamber 1 is completely open. The flow dividers 3 include a frame 31, a first sealing ring 32, and a filter. The filter plate 33 is provided with densely distributed powder filter holes. The inner wall of the frame 31 is provided with a receiving groove.

[0026] Specific implementation process: The air inlet (exhaust port) adopts a one-to-four distribution structure, dividing the entire cavity into four evenly distributed vacuum chambers. All connections between pipes use special elbows to ensure that the distance from the main exhaust port to the four distribution ports is consistent, thereby guaranteeing uniform airflow velocity. Simultaneously, the vacuum chamber contains multiple layers of removable distribution plates. By adjusting the thickness of the distribution plates, the distribution of holes, and the number of layers, uniform internal airflow can be achieved.

Then, the filter plate with the first sealing ring on its periphery is placed inside the frame from top to bottom, so that the second sealing ring is fully engaged in the groove. Next, a second sealing ring of the rectangular frame structure is also placed in the groove at the top of the filter plate. Finally, a rectangular piece is welded to the inner top of the frame, forming the inner top extension of the frame.
