Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying oven technology, and in particular to a particle drying oven. Background Technology
[0002] An oven is a commonly used drying device for drying various substances, such as granular samples. However, most existing ovens use a direct-flow method to blow hot air onto the surface of the granular samples for drying. Because granular objects are lightweight, dust can easily accumulate inside the oven, reducing drying efficiency. Furthermore, some airborne dust can enter the oven with the hot airflow and mix with the granular samples, thus lowering the drying quality. To address these issues, a solution is proposed below. Utility Model Content
[0003] The purpose of this invention is to provide a particle drying oven that has the advantages of preventing dust, high drying efficiency, and good drying quality.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0005] A particle drying oven includes a box body. A support column is fixedly mounted on the bottom of the box body. A placement seat is fixedly mounted on the upper end of the support column. A drying cylinder is placed on the upper end of the placement seat. A clamping mechanism is also provided on the placement seat and cooperates with the drying cylinder. A fixed seat is fixedly mounted on the upper end of the box body. A rotatable hollow tube is also passed through the upper end of the box body and is rotatably connected to the fixed seat. A turntable is provided inside the box body, and the lower end of the hollow tube is fixedly connected to the turntable and communicates with the interior of the turntable. The lower end of the turntable... The enclosure is connected to two conveying pipes, each with several blowing ports on one side. The blowing ports are all inclined. A motor is installed on the top of the enclosure, and a main gear is fixed to the output shaft of the motor. A moving gear is fixed to the hollow tube, and the main gear meshes with the moving gear. A hot air box is installed at the top of the enclosure. An air supply pipe is connected to one side of the hot air box, and the other end of the air supply pipe passes through the upper end of the hollow tube. An air inlet pipe is connected to the other side of the hot air box, and a removable filter screen is installed inside the air inlet pipe.
[0006] Preferably, the clamping mechanism includes two clamping blocks, the upper end of the placement seat is provided with two grooves, each groove is fixed with a sliding rod, a sliding slider passes through the sliding rod, the two clamping blocks are respectively fixed at the upper end of the clamping blocks, a retaining spring passes through the sliding rod, and the two ends of the retaining spring are respectively connected between the inner wall of the groove and one end of the slider.
[0007] Preferably, a number of fixing posts are provided on the outer side of the air intake pipe, the top ends of the fixing posts are respectively located inside the filter screen, and a return spring is provided on each fixing post, with the two ends of the return spring connected between the outer wall of the air intake pipe and the tail end of the fixing post.
[0008] Preferably, the surface of the drying cylinder is provided with a plurality of ventilation holes, all of which are inclined, and a support ring is fixedly provided on the inner side of the drying cylinder, on which a drying net is placed.
[0009] Preferably, the front end of the box is provided with a double-opening door, and the bottom of the box is equipped with several casters.
[0010] The beneficial effects of this utility model are as follows:
[0011] 1. The clamping mechanism can clamp and fix the drying cylinder, thus securing it to the placement seat for drying. The operator can place the particle sample at the bottom of the drying cylinder, then place the drying mesh on the top of the support ring, and continue placing particle samples on top of the drying mesh to increase the number of particle samples to be dried. The heat inside the chamber can then enter the drying cylinder through several ventilation holes, thereby increasing the drying efficiency of the particle samples inside the drying cylinder. Furthermore, since the ventilation holes are all inclined, hot airflow can be prevented from directly blowing onto the particle samples and causing them to be blown away.
[0012] 2. The rotation of the motor drives the main gear, which in turn drives the drive gear, which in turn drives the hollow tube. The rotation of the hollow tube drives the turntable, which in turn drives the two conveying pipes to rotate simultaneously. This, in turn, drives several blowing ports to rotate simultaneously. Since the blowing ports are all inclined, it can prevent the hot airflow from being directly blown onto the surface of the particle sample. Furthermore, the simultaneous rotation of several blowing ports can evenly distribute the hot airflow inside the chamber, making the heating inside the chamber more uniform and further ensuring the drying efficiency of the particle sample.
[0013] 3. The hot air box generates hot airflow during operation, which is then delivered to the hollow tube via the air supply pipe. The hot airflow is then delivered to the turntable through the hollow tube and finally blown out through several blowing ports. At the same time, the filter screen blocks dust from the air to prevent dust from entering the chamber with the hot airflow, thus ensuring the quality of particle sample drying.

[0020] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model's concept should be protected. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.
[0021] like Figures 1 to 5 As shown, a particle drying oven includes a box body 1. A support column 2 is fixedly provided at the bottom of the box body 1. A placement seat 3 is fixedly provided at the upper end of the support column 2. A drying cylinder 4 is placed at the upper end of the placement seat 3. A clamping mechanism 5 is also provided on the placement seat 3. The clamping mechanism 5 cooperates with the drying cylinder 4. The drying cylinder 4 can be clamped and fixed by the clamping mechanism 5, so that the drying cylinder 4 can be fixed on the placement seat 3 for drying.
[0022] The clamping mechanism 5 includes two clamping blocks 18. The upper end of the placement seat 3 is provided with two grooves 19. A slide rod 20 is fixed in each of the two grooves 19. A slidable slider 21 passes through the slide rod 20. The two clamping blocks 18 are fixed in the upper end of the clamping blocks 18. A clamping spring 22 passes through the slide rod 20. The two ends of the clamping spring 22 are respectively connected between the inner wall of the groove 19 and one end of the slider 21. By pushing the two clamping blocks 18 outward, the two clamping blocks 18 can be moved away from each other. At this time, the clamping blocks 18 can drive the slider 21 to slide along the slide rod 20, so that the clamping spring 22 is compressed and generates elastic force. When the drying cylinder 4 is placed in the upper end of the placement seat 3, it can be driven back to the initial position by the reset action of the clamping spring 22, so that the clamping blocks 18 can be driven to fit against both sides of the drying cylinder 4. Finally, the drying cylinder 4 can be clamped and fixed to ensure the stability of the drying cylinder 4 during drying.
[0023] The surface of the drying cylinder 4 has several ventilation holes 25, all of which are inclined. A support ring 26 is fixed inside the drying cylinder 4, and a drying net 27 is placed on the support ring 26. The operator can place the particle sample at the bottom of the drying cylinder 4, and then place the drying net 27 on the top of the support ring 26. Particle samples can be placed on the top of the drying net 27 to increase the number of particle samples to be dried. Then, the heat inside the chamber 1 can enter the drying cylinder 4 through the ventilation holes 25, thereby increasing the drying efficiency of the particle samples inside the drying cylinder 4. Furthermore, since the ventilation holes 25 are inclined, hot air can be prevented from blowing directly onto the particle samples and causing them to be blown away.
[0024] A fixed base 6 is fixedly installed at the upper end of the housing 1. A rotatable hollow tube 7 is also installed through the upper end of the housing 1, and the hollow tube 7 is rotatably connected to the fixed base 6. A turntable 8 is provided inside the housing 1, and the lower end of the hollow tube 7 is fixedly connected to the turntable 8 and communicates with the interior of the turntable 8. Two conveying pipes 9 are connected to the lower end of the turntable 8. Several blowing ports 10 are connected to one side of each conveying pipe 9. The blowing ports 10 are all inclined. A motor 11 is installed on the top of the housing 1. A main gear 12 is fixedly installed on the output shaft of the motor 11. A moving gear 13 is fixedly installed on the hollow tube 7, and the main gear 12 and the moving gear 13 are connected. The meshing mechanism allows the main gear 12 to rotate via the rotation of motor 11, which in turn drives the drive gear 13 to rotate, ultimately rotating the hollow tube 7. The rotation of the hollow tube 7 drives the turntable 8 to rotate, which in turn drives the two conveying pipes 9 to rotate simultaneously. This, in turn, drives several blowing ports 10 to rotate simultaneously. Since the blowing ports 10 are all inclined, it prevents the hot airflow from being directly blown onto the surface of the particle sample. Furthermore, the simultaneous rotation of the blowing ports 10 allows the hot airflow to be evenly distributed inside the chamber 1, resulting in more uniform heating inside the chamber 1 and further ensuring the drying efficiency of the particle sample.
[0025] A hot air box 14 is installed at the upper end of the chamber 1. One side of the hot air box 14 is connected to an air supply pipe 15, and the other end of the air supply pipe 15 passes through the upper end of a hollow tube 7. The other side of the hot air box 14 is connected to an air inlet pipe 16, and a removable filter screen 17 is installed inside the air inlet pipe 16. The hot air box 14 generates a hot airflow, which is delivered to the hollow tube 7 via the air supply pipe 15. The hot airflow is then delivered to the turntable 8 through the hollow tube 7 and finally blown out through several blowing ports 10. Simultaneously, the filter screen 17 blocks dust from entering the chamber 1 along with the hot airflow, further ensuring the quality of the dried particle samples. The structure and operation of the hot air box 14 are existing technologies and will not be described in detail.
[0026] Several fixing posts are installed on the outside of the intake pipe, with the tops of each post located inside the filter screen. Each fixing post is equipped with a return spring, and the two ends of the return spring are connected between the outer wall of the intake pipe and the tail end of the fixing post. By pulling the fixing posts, the tops of the fixing posts can be dislodged from the filter screen. At this time, the return spring is stretched and generates elastic force, which allows the filter screen to be removed and cleaned to remove the dust attached to the filter screen. Afterwards, the filter screen can be installed back in its initial position, and the return spring will drive the fixing posts back to their initial positions, so that the tops of the fixing posts can be pushed back into the filter screen to fix the filter screen.
[0027] The front of the chamber is equipped with a double-opening door, and the bottom of the chamber is equipped with several casters. By opening the door, the drying cylinder can be easily removed and placed, thus enabling the drying of particle samples. The casters also facilitate the movement and fixation of the entire device.
[0028] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
