Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of spray drying, and in particular to a spray drying device. Background Technology
[0002] In the industrial production field, the drying process after spraying plays a key role in ensuring the appearance quality and coating performance of products. For example, automotive parts, precision instrument housings and other products all require efficient and uniform drying to ensure the adhesion and durability of the coating.
[0003] However, existing spray drying equipment has significant structural design flaws: traditional drying racks are mostly arranged in a straight line or in a simple, dispersed layout. This arrangement not only fails to make full use of space but also makes it difficult to achieve uniform drying of items from all angles, easily leading to localized over-drying or under-drying, severely affecting product quality stability. At the same time, the unreasonable layout results in a lack of systematic fan configuration, making it difficult to create an efficient circulating drying airflow, leading to increased energy consumption, prolonged drying time, and low production efficiency. Utility Model Content

[0024] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0025] The spraying and drying apparatus of this utility model embodiment will now be described with reference to the accompanying drawings.
[0026] like Figures 1-4 As shown, the spray drying device of this utility model embodiment includes:
[0027] The equipment frame 1 is provided with a first base 101 and a second base 102. The equipment frame 1 is also provided with a ventilation duct 103. The equipment frame 1 is the main support structure of the device. It is made of metal profiles such as steel pipes and aluminum alloys, welded or bolted together, and has sufficient strength and rigidity to bear the weight of each component and the vibration load during operation.
[0028] The equipment frame 1 is used to install core components such as drive motors, heating devices, and control systems (not shown in the figure), or to integrate auxiliary structures such as shock-absorbing pads and leveling bolts to reduce vibration transmission.
[0029] The drying rack assembly includes multiple drying racks 3 arranged in a ring array around the equipment frame 1, and the air duct 103 is connected to each drying rack 3.
[0030] The annular center of all the drying racks coincides with the geometric center of the equipment frame 1, and the distance between adjacent drying racks is equal, forming a 360° drying area without dead angles. This ensures that all parts of the workpiece surface receive equal airflow, solving the "drying blind spot" problem of traditional linear layouts.
[0031] Airflow connectivity: Each drying rack 3 is connected to the air duct 103 through an independent air duct or branch pipe. The ventilation duct can be a rigid pipe or a flexible hose. The hot air or normal temperature airflow in the air duct is distributed to each drying rack after being diverted, forming a distributed air supply system with uniform air pressure.
[0032] The fan 4 installed on each air drying rack 3 is preferably an axial flow fan or a centrifugal fan. The inner wall of the fan cavity is adapted to the fan shell to form a sealed or semi-sealed airflow channel, reducing air leakage and guiding the airflow to directional output.
[0033] After being powered on, the blower 4 operates at high speed, drawing in and accelerating the airflow from the air duct 103, and then blowing it onto the workpiece to be dried through the outlet of the drying rack. When the blowers in the ring array work synchronously, a surrounding airflow field can be formed around the workpiece, which is especially suitable for all-round drying of cylindrical and irregular curved workpieces, avoiding local over-drying or under-drying caused by traditional single-sided air supply.
[0034] In one embodiment of this application, the air drying rack 3 is provided with a fan cavity 5, and the fan 4 is installed in the fan cavity 5, with the fan cavity 5 and the fan 4 being adapted to each other.
[0035] Specifically, the fan cavity 5 on the drying rack 3 is a dedicated mounting cavity for the fan 4. Its inner wall shape and size are precisely matched with the fan shell to form a stable mounting structure. The fan cavity 5 not only provides positioning support for the fan, but also guides the airflow output by the fan to flow evenly to the drying area through adaptive design, reducing airflow leakage and resistance.
[0036] In one embodiment of this application, the air drying rack 3 is provided with a mesh plate 6, which is located on the air outlet side of the fan 4.
[0037] Specifically, the mesh plate transforms the high-speed airflow from the fan into a uniform low-speed airflow, which, combined with the circular array of drying racks, significantly improves drying uniformity. Simultaneously, the mesh plate's support simplifies the workpiece clamping process, making it suitable for rapid loading and unloading in automated production lines.
[0038] The evenly distributed small holes on the mesh plate divide the concentrated high-speed airflow blown out by the fan into multiple fine streams. Each stream of air diffuses outwards after passing through the small holes, forming a radial flow.
[0039] In one embodiment of this application, a crossbeam 7 is provided on the equipment frame 1, the crossbeam 7 is connected to the frame plate 8, the frame plate 8 is configured in cooperation with the folding plate 9, and the folding plate 9 is spaced apart from the frame plate 8.
[0040] Specifically, the rack 8 and the folding plate 9 work together to form multiple placement spaces, which can be used to place items to be dried in an orderly manner.
[0041] In one embodiment of this application, the fan 4 is connected to the air duct 103 via an air duct.
[0042] Specifically, the fan 4 is connected to the air duct 103 through the air duct, forming the core airflow transmission path of the spray drying device. Its function is to efficiently transport the hot air or normal temperature airflow in the air duct to each drying rack 3.
[0043] In one embodiment of this application, the center of the ring of a plurality of air drying racks 3 arranged in a ring array coincides with the center of the equipment frame 1, and the spacing between adjacent air drying racks 3 is equal.
[0044] Specifically, multiple drying racks 3 are evenly distributed in a ring around the center of the equipment frame 1, with equal spacing between adjacent racks. This symmetrical layout ensures that the airflow evenly covers the workpiece 360°, eliminating drying blind spots, and the air supply pressure of each drying rack is consistent, improving drying uniformity and equipment space utilization.
[0045] In summary, the spraying and drying device of this utility model embodiment can efficiently complete the drying operation of sprayed workpieces, can be flexibly placed according to the shape of the workpiece, and the airflow covers the entire process during drying, effectively ensuring the uniformity of the drying effect; it can maintain stability during operation and reduce external interference; it is convenient to clean and maintain after the operation is completed; and it has good flexibility in applicable scenarios, which can meet the drying needs of workpieces of different sizes and types.
