Description

Technical Field

[0001] This utility model belongs to the technical field of drying devices for enamel processing, specifically a drying device for enamel processing with uniform heating. Background Technology

[0002] Enamel products are composite materials formed by coating a metal substrate with a vitreous glaze and sintering at high temperature. The processing flow mainly includes substrate pretreatment, glaze coating, drying and sintering. Among them, the drying process aims to remove moisture and organic solvents from the coated glaze. If the drying is not thorough and sintering is done directly, it will lead to glaze bubbles, peeling or substrate oxidation, which will seriously affect the strength and appearance quality of enamel products.

[0003] Existing drying equipment typically uses static heating, with the trays fixed in place. This results in a single heated surface for enamel products, especially when multiple layers are stacked. Lower-layer enamel products are easily blocked by upper layers, leading to large local temperature differences, which can cause glaze cracking or color variations, thus affecting drying quality. Furthermore, since the spacing between trays is usually fixed, it cannot be flexibly adjusted according to the height of the enamel products. When small enamel products are stacked, heat radiation is obstructed, while for large products, the excessive spacing prolongs the drying time, resulting in low drying efficiency. Summary of the Invention

Multiple slots are opened on both sides of the support rod, and two limiting components are installed at the lower ends of the multiple loading trays. The two limiting components are symmetrically arranged.

[0008] As a preferred embodiment of the above technical solution, the limiting component includes a limiting block, which is fixedly connected to the lower end of the loading tray.

A toggle block is slidably connected in the opening of the sliding groove. The toggle block is fixedly connected to one side of the movable plate.

[0009] As a preferred embodiment of the above technical solution, the hot air assembly includes an air inlet chamber and an exhaust chamber, both of which are located inside the housing.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Please see Figures 1-5 As shown, this utility model provides a technical solution: a drying device for enamel processing with uniform heating, including a protective box 1 and casters 2 for movement. Four casters 2 are provided and fixedly installed at the four corners of the lower end of the box 1. A loading component 3 for placing objects is installed on the inner wall of the box 1, and a hot air component 4 for drying is installed inside the box 1.

[0018] Furthermore, by setting up a rotatable carrier component 3, the various surfaces of the enamel products on the carrier component 3 are alternately impacted by hot airflow, eliminating local temperature differences caused by airflow obstruction during static drying. The spacing of the carrier component 3 can be freely adjusted according to the height of the enamel products, ensuring that the products on both the upper and lower layers receive sufficient heat radiation when multiple layers of enamel products are placed, significantly improving heat utilization rate, shortening the drying cycle and improving drying quality. The hot air component 4 ensures that the hot air is covered without dead angles inside the chamber 1 through bidirectional airflow circulation. At the same time, the hot air component 4 can recover and utilize the heat of the exhaust gas, which not only improves drying efficiency and drying quality but also reduces production costs.

[0019] A heat-insulating door is hinged to one side of the chamber 1. During drying, closing the heat-insulating door creates a sealed space inside the chamber 1, effectively preventing the leakage of internal heat. A temperature sensor is installed inside the chamber 1 to monitor the internal temperature. The temperature sensor monitors the internal temperature of the chamber 1 in real time and feeds the data back to the control device. Combined with the sealed structure of the heat-insulating door, a precise temperature control environment is formed. The universal wheels 2 at the bottom of the chamber 1 facilitate the movement of the device, improving its portability. The universal wheels 2 are equipped with a self-locking component, which allows the device to be fixed after being moved to a designated position, ensuring that the device can perform drying operations stably.

[0020] As one implementation method in this embodiment, please refer to Figure 3 and Figure 4 As shown, the loading component 3 includes a first bevel gear 301 and a motor 302. The first bevel gear 301 is rotatably connected to the middle of the bottom of the inner wall of the housing 1. The motor 302 is fixedly installed on the lower side wall of the housing 1. The output end of the motor 302 passes through the housing 1. The output end of the motor 302 is fixedly connected to a second bevel gear 303. The first bevel gear 301 and the second bevel gear 303 mesh with each other. The upper end of the first bevel gear 301 is fixedly connected to a support rod 304. Multiple loading trays 305 are slidably sleeved on the outside of the support rod 304. Multiple slots 306 are opened on both sides of the support rod 304. Two limiting components are installed at the lower end of the multiple loading trays 305. The two limiting components are symmetrically arranged.

[0021] Furthermore, during the drying process, the motor 302 drives the second bevel gear 303 to rotate through the output shaft, which meshes with the first bevel gear 301 located at the bottom of the housing 1, thereby driving the support rod 304 and the tray 305 to rotate at a uniform speed, so that each surface of the enamel product is alternately impacted by the hot airflow, eliminating the local temperature difference caused by airflow obstruction during static drying. This not only shortens the drying cycle but also further improves the drying quality. In addition, the tray 305 is provided with multiple ventilation holes to ensure that the airflow flows evenly between each tray 305.

[0022] As one implementation method in this embodiment, please refer to Figure 3 and Figure 4As shown, the limiting component includes a limiting block 307, which is fixedly connected to the lower end of the loading tray 305. A sliding groove 308 is provided on one side of the limiting block 307. A spring 309 is fixedly connected to the inner wall of the sliding groove 308 away from the support rod 304. A movable plate 310 is slidably connected in the sliding groove 308. The movable plate 310 is fixedly connected to the end of the spring 309 near the support rod 304. A locking block 311 is fixedly connected to the side of the movable plate 310 away from the spring 309. The locking block 311 passes through the limiting block 307 and engages with the locking groove 306. A toggle block 312 is slidably connected in the groove of the sliding groove 308. The toggle block 312 is fixedly connected to one side of the movable plate 310.

[0023] Furthermore, the distance between the trays 305 can be adjusted according to the height of the enamel products. During adjustment, the actuating block 312 is pushed, the spring 309 retracts, and the moving plate 310 slides in the sliding groove 308, causing the locking block 311 to slide out of the locking groove 306. The locking block 311 releases the restriction on the trays 305. When the trays 305 are adjusted to the appropriate height, the actuating block 312 is released, the spring 309 returns to its original position, and the locking block 311 can move into the locking groove 306, thereby achieving the restriction and fixation of the trays 305. This allows the height between the trays 305 to be adjusted to accommodate enamel products of different heights, ensuring that both the upper and lower layers of products can receive sufficient heat radiation when multiple layers are placed. If drying an enamel jar with a height of 15 cm, adjusting the distance between the trays 305 to 25 cm can prevent the upper jar from blocking the hot airflow of the lower layer, significantly improving the heat utilization rate.

[0024] As one implementation method in this embodiment, please refer to Figure 5 As shown, the hot air assembly 4 includes an air inlet chamber 401 and an exhaust chamber 402. Both the air inlet chamber 401 and the exhaust chamber 402 are located inside the housing 1. The exhaust chamber 402 is located outside the air inlet chamber 401. An air inlet 403 is provided at the bottom of the inner wall of the air inlet chamber 401. An air intake fan 404 is fixedly installed on the inner wall of the air inlet 403. An exhaust fan 405 is installed on the top of the inner wall of the housing 1. The output end of the exhaust fan 405 is connected to the interior of the exhaust chamber 402. Multiple exhaust holes 406 are opened on both sides of the inner wall of the exhaust chamber 402. Multiple air inlets 407 are provided on both sides of the inner wall of the air inlet chamber 401. The multiple air inlets 407 are all connected to the inside of the housing 1. Multiple guide plates 408 are fixedly connected to the inner wall of the air inlet chamber 401. Multiple heating rods 409 are fixedly installed on the inner wall of the air inlet chamber 401.

[0025] Furthermore, during the drying process, external air enters through the air inlet 403, which is equipped with a dust filter at the lower end to prevent external dust from entering the air inlet chamber 401. After being pressurized by the air intake fan 404, the air flows through the heating rod 409 area and is heated. The guide plate 408 can prolong the residence time of the gas in the air inlet chamber 401, thereby ensuring uniform heating of the gas. Then, the hot air enters the interior of the chamber 1 through the air inlet 407, and the humid air is drawn into the exhaust chamber 402 by the top exhaust fan 405 and then discharged through the exhaust port 406, ensuring that the hot air is covered without dead corners inside the chamber 1. The residual heat of the gas discharged from the exhaust chamber 402 preheats the gas in the air inlet chamber 401, realizing heat recovery. This not only improves drying efficiency and drying quality but also reduces production costs.

[0026] Heating rod 409 is existing technology. Heating rod 409 is mainly composed of heating element, insulation layer and metal shell. Its working principle is based on resistance heating effect. When current passes through heating element, resistance material generates Joule heat due to electron collision. Electrical energy is converted into heat energy. Together with the temperature detector inside box 1, it realizes precise temperature control inside box 1. It will not be described in detail here.

[0027] Working principle: First, adjust the distance between the trays 305 according to the height of the enamel products. During adjustment, push the actuating block 312, the spring 309 retracts, and the moving plate 310 slides in the sliding groove 308, causing the locking block 311 to slide out of the locking groove 306. The locking block 311 releases the restriction on the trays 305. When the trays 305 are adjusted to the appropriate height, release the actuating block 312, the spring 309 returns to its original position, and the locking block 311 can move into the locking groove 306, thereby achieving the restriction and fixation of the trays 305. This allows the height between the trays 305 to be adjusted to accommodate enamel products of different heights, ensuring that the products on both the upper and lower layers receive sufficient heat radiation when multiple layers are placed, significantly improving heat utilization. After adjustment, place the enamel products on top of the trays 305. During drying, external air enters through the air inlet 403 and is heated by the air intake fan 404. After being compressed, the air flows through the heating rod 409 area and is heated. Then, the hot air enters the interior of the chamber 1 through the air inlet 407. The humid air is drawn into the exhaust chamber 402 by the top exhaust fan 405 and discharged through the exhaust port 406, ensuring that the hot air is covered without dead corners inside the chamber 1. The residual heat of the gas discharged from the exhaust chamber 402 can preheat the gas in the air inlet chamber 401, realizing heat recovery. This not only improves the drying efficiency and drying quality but also reduces production costs. During the drying process, the motor 302 drives the second bevel gear 303 to rotate through the output shaft. This gear meshes with the first bevel gear 301 located at the bottom of the chamber 1, thereby driving the support rod 304 and the tray 305 to rotate at a uniform speed. This allows each surface of the enamel product to be alternately impacted by the hot airflow, eliminating the local temperature difference caused by airflow obstruction during static drying. This not only shortens the drying cycle but also further improves the drying quality.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
