Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a hot air circulating drying oven. Background Technology

[0002] Hot air circulating ovens are a common type of drying equipment widely used in various industries such as food, chemical, and pharmaceutical. Their working principle involves a fan sending air into a heating device; the heated air then circulates within the oven, thus drying the materials placed inside.

[0003] When using a hot air circulating oven to dry medicinal herbs and other materials, it is usually necessary to open the oven door and turn the materials over during the drying process to ensure uniform drying. However, frequent opening of the oven door leads to a significant loss of heat inside the oven, increasing energy consumption, prolonging drying time, reducing production efficiency, and causing large fluctuations in the temperature field inside the oven, affecting the drying quality of the materials. Furthermore, operators may suffer burns from the high temperatures while turning the materials over, posing a certain safety hazard.

[0004] The reason for this problem is that the degree and duration of contact between the material and the hot air vary during the drying process. Materials located in the upper layers or near the air outlets experience smoother hot air circulation and more thorough heat exchange, resulting in faster drying. However, materials in the lower layers or corners are difficult for the hot air to reach, leading to insufficient and uneven drying. Therefore, we propose a hot air circulating oven to solve this problem. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a hot air circulating drying oven. This solves the problem of excessive heat loss from the oven interior due to frequent opening of the oven door, which not only increases energy consumption and prolongs drying time, reducing production efficiency, but also causes significant temperature fluctuations within the oven, affecting the drying quality of the materials. Furthermore, the process of opening the door to turn over materials poses a safety hazard as operators may suffer burns from the high temperatures.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a hot air circulating oven, including a box body, wherein a uniform drying unit for drying raw materials is provided inside the box body, and the uniform drying unit includes a drying box, a vibration motor and synchronous vibration;

[0007] The drying boxes are arranged in a vertical array inside the box body, and the drying boxes are hollow structures. The vibration motor is located at the bottom of the box body. The synchronous vibration components are located on both sides of the vibration motor. The synchronous vibration components are connected to the drying boxes for driving, and the vibration motor drives the drying boxes to vibrate synchronously through the synchronous vibration components.

[0008] Preferably, the synchronous vibration component includes a connecting rod and a transverse groove;

[0009] The transverse grooves are respectively formed in the inner wall of the connecting rod and the box body.

[0010] Preferably, the synchronous vibration component further includes a slider and a support plate;

[0011] The slider is slidably disposed inside the transverse groove; the support plate is disposed below the drying box, and the support plate is fixedly assembled with the slider.

[0012] Preferably, the synchronous vibration component further includes a slide, a movable block, and a spring;

[0013] The slide groove is formed inside the support plate and is distributed in a rectangular array; the movable block is fixedly assembled at the bottom of the support plate and slidably connected inside the slide groove; the spring is disposed inside the slide groove, one end of the spring is fixedly assembled with the movable block and the other end of the spring is fixedly assembled with the slide groove.

[0014] Preferably, the vibration motor has a rotating shaft inside, and irregularly shaped blocks are provided on both sides of the vibration motor, and the irregularly shaped blocks are fixedly assembled with the rotating shaft.

[0015] Preferably, the vibration motor is provided with protective shells on both sides, and a connecting block is fixedly assembled on one side of the protective shell, and the connecting block is fixedly assembled with the connecting rod.

[0016] Preferably, a bottom plate is provided at the bottom of the box, and a support leg is provided at the bottom of the box, with a rubber block provided between the support leg and the bottom plate.

[0017] This utility model discloses a hot air circulating drying oven, which has the following beneficial effects: The device drives the drying box to vibrate through a vibration motor in the uniform drying unit, so that the material moves continuously inside the drying box. There is no need to open the oven door to turn the material, which avoids heat loss, reduces energy consumption, shortens drying time, and improves production efficiency. The continuous vibration of the material inside the drying box can ensure that all parts of the material are in full and uniform contact with the hot air, ensuring the uniformity of drying and improving the drying quality of the material.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This application provides a hot air circulating oven, which solves the problem that frequent opening of the oven door leads to significant heat loss, increasing energy consumption, prolonging drying time, reducing production efficiency, and causing large fluctuations in the temperature field inside the oven, affecting the drying quality of the materials. Furthermore, the process of opening the door to turn over materials poses a safety hazard as operators may suffer burns from the high temperature.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] This utility model provides, for example Figure 1-4 The hot air circulating oven shown.

[0029] Example 1: Includes a box 1, and the inside of the box 1 is provided with a uniform drying unit 2 for drying raw materials. The uniform drying unit 2 includes a drying box 21, a vibration motor 22 and a synchronous vibration component 23.

[0030] The drying boxes 21 are arranged in a vertical array inside the box 1, and the drying boxes 21 are hollow structures. The vibration motor 22 is located at the bottom of the box 1. The synchronous vibration element 23 is located on both sides of the vibration motor 22. The synchronous vibration element 23 is connected to the drying box 21 for driving. The vibration motor 22 drives the drying box 21 to vibrate synchronously through the synchronous vibration element 23.

[0031] The synchronous vibration component 23 includes a connecting rod 231 and a transverse groove 232. The transverse groove 232 is respectively opened in the inner wall of the connecting rod 231 and the housing 1. The synchronous vibration component 23 also includes a slider 233 and a support plate 234. The slider 233 is slidably disposed inside the transverse groove 232. The support plate 234 is disposed below the drying box 21 and is fixedly assembled with the slider 233. The synchronous vibration component 23 also includes a sliding groove 235, a movable block 236 and a spring 237. The sliding groove 235 is opened inside the support plate 234 and is distributed in a rectangular array. The movable block 236 is fixedly assembled at the bottom of the support plate 234 and is slidably connected inside the sliding groove 235. The spring 237 is disposed inside the sliding groove 235, with one end of the spring 237 fixedly assembled with the movable block 236 and the other end of the spring 237 fixedly assembled with the sliding groove 235.

[0032] In this embodiment, during equipment operation, the power generated by the vibration motor 22 after startup is transmitted to the drying box 21 through the synchronous vibration components 23 on both sides. The connecting rod 231 in the synchronous vibration component 23, the transverse groove 232 on the inner wall of the box 1, and the slider 233 form a sliding connection structure. When the vibration motor 22 operates, it drives the connecting rod 231 to move, and the slider 233 slides within the transverse groove 232, thereby driving the support plate 234, which is fixedly mounted to the slider 233, to move, thus causing the drying box 21 to vibrate. Simultaneously, the sliding groove 235, the movable block 236, and the spring 237 inside the support plate 234 function. The movable block 236 slides within the sliding groove 235, and the spring 237 provides cushioning, ensuring the drying box 21 remains stable during vibration and preventing excessive vibration amplitude from affecting the drying effect and equipment performance.

[0033] This utility model discloses a hot air circulating oven. More specifically, based on Embodiment 1, it is provided according to the appendix... Figure 1 , 5 As shown.

[0034] Example 2: Includes a box 1, and the inside of the box 1 is provided with a uniform drying unit 2 for drying raw materials. The uniform drying unit 2 includes a drying box 21, a vibration motor 22 and a synchronous vibration component 23.

[0035] The drying boxes 21 are arranged in a vertical array inside the box 1, and the drying boxes 21 are hollow structures. The vibration motor 22 is located at the bottom of the box 1. The synchronous vibration element 23 is located on both sides of the vibration motor 22. The synchronous vibration element 23 is connected to the drying box 21 for driving. The vibration motor 22 drives the drying box 21 to vibrate synchronously through the synchronous vibration element 23.

[0036] The vibration motor 22 has a rotating shaft inside. The vibration motor 22 has irregularly shaped blocks 24 on both sides. The irregularly shaped blocks 24 are fixedly assembled with the rotating shaft. The vibration motor 22 has protective shells 25 on both sides.

A bottom plate is provided at the bottom of the box body 1. Support legs are provided at the bottom of the box body 1. Rubber blocks are provided between the support legs and the bottom plate.

[0037] In this embodiment, the rotating shaft inside the vibration motor 22 begins to rotate, and the irregularly shaped blocks 24 fixedly mounted on both sides of the rotating shaft rotate accordingly. Due to the special shape of the irregularly shaped blocks 24, a vibration effect is generated during rotation. The protective shells 25 on both sides of the vibration motor 22 are fixedly mounted to the connecting rods 231 through connecting blocks 26. While protecting the vibration motor 22, they also stably transmit the vibration generated by the vibration motor 22 to the drying box 21 through the synchronous vibration component 23. In addition, the bottom plate, bottom support legs, and rubber blocks between the support legs and the bottom plate provided under the box 1 can effectively reduce the vibration and noise generated by the vibration motor 22 during operation, ensuring the stability of equipment operation.
