Description

Technical Field

[0001] This utility model relates to the field of drying oven technology, and in particular to a circulating air drying oven. Background Technology

[0002] Drying ovens are divided into two main categories based on the type of material being dried: electric heating forced-air drying ovens and vacuum drying ovens. Electric heating forced-air drying ovens, also known as "baking ovens," use electric heating to circulate air for drying.

[0003] Drying ovens are used in various industries such as chemical, pharmaceutical, casting, automotive, food, machinery, and construction engineering. For example, before conducting tests on cement strength, mortar and concrete compressive strength, tensile strength, or the water absorption rate of stone, the samples need to be thoroughly dried to the standard moisture content to ensure the accuracy of the test results. Drying ovens provide precise temperature and humidity control, ensuring the standardization of the drying process.

[0004] A search revealed that Chinese utility model patent CN219415600U discloses a closed-loop circulation dryer, including a base plate. A nitrogen tank, a fan, and a drying chamber are sequentially arranged on the base plate, connected in sequence. A heating chamber with heating wires is located inside the drying chamber. The heating chamber and the fan are connected via an air inlet pipe. An air outlet pipe connected to the heating chamber is located at the bottom of the drying chamber, and at least one air outlet hood is installed on the air outlet pipe. A feed inlet is located at the top of the drying chamber, and a conveyor belt is located below the feed inlet inside the drying chamber. This application utilizes a conveyor belt to apply hot airflow to the material during transport to achieve material drying. However, the conveyor belt can obstruct the airflow, making it difficult for the material to fully contact the airflow, thus affecting the drying efficiency. Utility Model Content

[0005] In view of the above-mentioned prior art, the present invention provides a circulating air drying box, which mainly solves the technical problem of how to ensure the drying efficiency of materials.

[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0007] A circulating air drying oven includes a box body, a fan, and heating wires. The box body is equipped with a driving mechanism and a turning mechanism. The turning mechanism includes several mesh cylinders for holding materials. The driving mechanism drives the mesh cylinders to rotate, and the mesh cylinders turn the materials by rotating themselves. The box body is equipped with a drying mechanism, which includes pipes and a drying chamber. The fan and heating wires circulate hot air into the box body through the pipes, and the drying chamber is used to dehumidify the airflow in the pipes.

[0008] Furthermore, a sliding hole is provided on one side of the box, and a connecting rod is slidably connected to the box at the sliding hole. A handle is fixedly connected to one end of the connecting rod outside the box. A claw frame is rotatably connected to the other end of the connecting rod and the inner wall of the other side of the box. A locking pin is fixedly connected to each claw of the two claw frames. A material outlet is provided on one side of the box, and a door is rotatably connected to the box at the material outlet.

[0009] Furthermore, the number of clamps on the two claw frames is the same and they correspond to each other on the left and right. The net cylinder is set between the two corresponding clamps on the left and right. The net cylinder includes a cylinder body and a cylinder cover. The cylinder cover is threaded to the outside of one end of the cylinder body. The cylinder body and the cylinder cover are provided with a clamping groove on the side away from each other. The clamping groove is adapted to the clamp.

[0010] Furthermore, a driven wheel is connected to the outside of the claw holder away from the handle via a key. A circular through hole is provided at the bottom end of the driven wheel on the side of the housing away from the handle. A housing is fixedly connected to the outside of the circular through hole. The drive mechanism includes a motor, which is fixedly connected inside the housing. One end of the motor's output shaft extends into the inside of the housing through the circular through hole. A drive wheel is connected to one end of the motor's output shaft via a key. The drive wheel meshes with the driven wheel, and the diameter of the drive wheel is smaller than the diameter of the driven wheel.

[0011] Furthermore, the drying chamber is fixedly connected to the top center of the box body. Air outlets are provided on both sides of the drying chamber and at the top of both sides of the box body. Covers are fixedly connected to both the box body and the drying chamber at the air outlets. There are two pipes, which are located on both sides of the drying chamber, and the ends of the two pipes are fixedly connected to four covers respectively.

[0012] Furthermore, the drying oven includes an outer shell and a mesh box. The outer shell is fitted onto the bottom outer side of the mesh box and is fixedly connected to the box body.

A pad is provided at the bottom inside the mesh box, and the pad is made of sponge.

[0013] Furthermore, rubber feet are fixedly attached to the four corners of the bottom outer side of the box.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This device uses multiple mesh cylinders installed in the chamber. By driving the mesh cylinders to rotate, the material inside is tumbled. At the same time, the operation of the fan and heating wire generates a hot airflow, which applies hot air to the material. This ensures that the material is in full contact with the hot airflow, thus ensuring the drying efficiency of the device. Secondly, the pipeline allows the airflow to circulate, thus maintaining the cleanliness of the airflow. The drying chamber removes water vapor from the airflow during this process, thereby ensuring the drying efficiency of the material.

[0016] 2. By removing the mesh box from the outer shell and removing the cover plate from the baffle, it is easy to add or replace the desiccant in the mesh box. This allows the device to maintain its drying effect by replacing or adding the desiccant after a certain period of operation.

[0017] 3. The use of rubber feet increases the friction between the chamber and the ground or the platform on which the device is placed, thus enhancing the stability of the device during operation and ensuring a stable drying process. Attached Figure Description

Detailed Implementation

[0024] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the utility model.

[0025] Example 1

[0026] See attached document Figure 1-3 This application provides a circulating air drying box, including a box body 1, a fan and an electric heating wire. The box body 1 is provided with a driving mechanism and a turning mechanism. The turning mechanism includes several mesh cylinders 2, which are used to hold materials. The driving mechanism is used to drive the mesh cylinders 2 to rotate. The mesh cylinders 2 turn the materials by rotating themselves. The box body 1 is provided with a drying mechanism, which includes a pipe 9 and a drying chamber 11. The fan and the electric heating wire circulate hot airflow into the box body 1 through the pipe 9. The drying chamber 11 is used to dehumidify the airflow in the pipe 9.

[0027] Preferably, a sliding hole is provided on one side of the box body 1, and a connecting rod 12 is slidably connected to the box body 1 at the sliding hole. A handle 13 is fixedly connected to one end of the connecting rod 12 outside the box body 1. A claw frame 4 is rotatably connected to the other end of the connecting rod 12 and the inner wall of the other side of the box body 1. The claw frame 4 is a claw-shaped support with several claws. A locking pin 3 is fixedly connected to each claw of the two claw frames 4. A material opening is provided on one side of the box body 1, and a door is rotatably connected to the box body 1 at the material opening.

[0028] When using this device, you can first pull the handle 13 to move the connecting rod 12, so that the two claws 4 move away from each other. Then, remove the mesh cylinder 2, and after twisting the cylinder cover 202 to remove it, put the material to be dried into the cylinder 201.

[0029] Preferably, the number of stakes 3 on the two claw frames 4 is the same and they correspond to each other on the left and right. The net cylinder 2 is set between the two corresponding stakes 3 on the left and right. The net cylinder 2 includes a cylinder body 201 and a cylinder cover 202. The cylinder cover 202 is threaded to the outside of one end of the cylinder body 201. The cylinder body 201 and the cylinder cover 202 are provided with slots 203 on the opposite sides. The slots 203 are adapted to the stakes 3. The slots 203 and the stakes 3 have the same shape and diameter. When installing the net cylinder 2, the stakes 3 can be inserted into the slots 203 to provide temporary support for the net cylinder 2. Then, the stakes 3 on the other side can be adjusted to be inserted into the slots 203 on the other side of the net cylinder 2 to achieve stable support for the net cylinder 2.

[0030] After that, the cover 202 can be reinstalled onto the cylinder 201, the complete mesh cylinder 2 can be placed between the two claws 4, and finally the handle 13 can be pushed to bring the two claws 4 closer to each other until the two locking pins 3 enter the slots 203 on the cylinder 201 and the cover 202 respectively, thus completing the process of loading materials into the device.

[0031] Preferably, a driven wheel 8 is connected to the outside of the claw holder 4 away from the handle 13 via a key. A circular through hole is opened at the bottom end of the driven wheel 8 on the side of the housing 1 away from the handle 13. A housing 7 is fixedly connected to the outside of the circular through hole of the housing 1. The drive mechanism includes a motor 6, which is fixedly connected inside the housing 7. One end of the output shaft of the motor 6 extends into the inside of the housing 1 through the circular through hole. One end of the output shaft of the motor 6 is connected to a driving wheel 5 via a key. The driving wheel 5 meshes with the driven wheel 8. The diameter of the driving wheel 5 is smaller than the diameter of the driven wheel 8. Therefore, the driving wheel 5 can achieve a deceleration effect when driving the driven wheel 8 to rotate. This ensures that the mesh cylinder 2 will not bring excessive centrifugal force to the material when it rotates. Therefore, it can ensure that the material will only roll and will not adhere to the inner wall of the mesh cylinder 2.

[0032] After all the mesh cylinders 2 have been filled with materials and installed in the box 1, the motor 6, fan and heating wire can be started. At this time, the fan and heating wire can generate a circulating hot airflow in the box 1 and the pipe 9. At the same time, the motor 6 drives the driven wheel 8 to rotate through the drive wheel 5. The driven wheel 8 can drive the mesh cylinder 2 to rotate through the claw frame 4 where it is located, thereby turning the material. This allows the material to come into full contact with the hot airflow, thereby achieving the effect of drying the material.

[0033] Preferably, the drying chamber 11 is fixedly connected to the top center of the chamber body 1. Air outlets are provided on both sides of the drying chamber 11 and at the top of both sides of the chamber body 1. Covers 10 are fixedly connected to both the chamber body 1 and the drying chamber 11 at the air outlets. There are two pipes 9, which are located on both sides of the drying chamber 11. The ends of the two pipes 9 are fixedly connected to four covers 10, that is, both ends of the two pipes 9 are fixedly connected to covers 10, and the two covers 10 on the same pipe 9 are fixedly connected to the chamber body 1 and the drying chamber 11 respectively.

[0034] Furthermore, during this process, the airflow passes through the drying chamber 11 as it flows through the pipe 9. At this time, the desiccant contained in the mesh box 1102 can dehumidify the airflow, thus maintaining the dryness of the airflow by removing water vapor, thereby ensuring the drying effect on the material.

[0035] Preferably, the drying chamber 11 includes an outer shell 1101 and a mesh box 1102. The outer shell 1101 is fitted onto the outer side of the bottom end of the mesh box 1102 and is fixedly connected to the chamber body 1. A baffle 15 is fixedly connected to the top of the outer side of the mesh box 1102. A cover plate 16 is provided at the top of the mesh box 1102. Connecting pieces are fixedly connected to the top of both sides of the outer shell 1101. Threaded through holes are provided on both sides of the cover plate 16, both sides of the baffle 15, and the connecting pieces. The cover plate 16, the baffle 15, and the connecting pieces are threadedly connected to the same bolt at the threaded through holes. A pad 14 is provided at the bottom of the inside of the mesh box 1102. The pad 14 is made of sponge. The sponge pad 14 can not only raise the desiccant so that it does not fall below the air outlet on the drying chamber 11, but also absorb the calcium chloride hydrate formed after the reaction of calcium chloride and water when using calcium chloride desiccant, thereby avoiding excessive accumulation of this substance in the drying chamber 11.

[0036] After the material is dried, the motor 6, fan and heating wire can be turned off, and the mesh cylinder 2 can be removed after the temperature in the chamber 1 drops. Then it can be disassembled to make it easier to take out the dried material.

[0037] As the device is used continuously, the desiccant in the mesh box 1102 will gradually become ineffective or be consumed. In this case, the cover plate 16 can be removed after loosening the bolts, and then desiccant can be added to the mesh box 1102. In addition, if it is necessary to replace the desiccant or clean the mesh box 1102, the mesh box 1102 can be removed from the outer casing 1101 by pulling the baffle 15 to facilitate the above operations.

[0038] Example 2

[0039] See attached document Figure 4 This application provides a circulating air drying oven. Compared with embodiment 1, in order to ensure the stable operation of this device, foot pads 17 are fixedly connected to the four corners of the bottom outer side of the box body 1. The material of the foot pads 17 is rubber.

[0040] The rubber foot pads 17 can increase the friction between the box 1 and the ground or the platform on which the device is placed, thereby maintaining the stability of the device during operation and ensuring the stable progress of the material drying process.
