Description

Technical Field

[0001] This utility model belongs to the field of chemical production technology, and in particular relates to a vibration drying device for chemical crystallizing particles. Background Technology

[0002] Crystallization refers to the process by which a solute precipitates out as crystals when a hot saturated solution is cooled, as the solubility of the solute decreases and the solution becomes supersaturated. During this process, the surface of the precipitated crystals remains moist. When processing these crystals, appropriate drying techniques are needed to quickly dry the moist crystal particles.

[0003] Chinese patent CN118168310B discloses a drying system for crystalline chemical particles, including a hot air furnace. A support is fixedly connected to the upper outer surface of the hot air furnace, and a feeding pipe is fixedly connected to the upper outer surface of the support. A feeding assembly is provided inside the feeding pipe to smoothly feed the moist chemical particles. A circulation assembly is provided on the upper side of the feeding pipe. By setting up the circulation assembly, the hot airflow simultaneously conveys the chemical particles during its flow. During conveying, the chemical particles come into full contact with the hot airflow, utilizing the heat of the airflow to dry them. Furthermore, the chemical particles collide with the inner wall of the conveying pipe during operation, loosening and breaking up any agglomerated particles. By increasing the contact area between the chemical particles and the hot air, the drying efficiency of the chemical particles can be effectively improved.

[0004] Several other patents, including the aforementioned patent, failed to consider the differences in crystal particle size when drying crystals. Larger crystals have lower drying efficiency, while smaller crystals have higher drying efficiency. The entire drying process did not distinguish between large and small crystals, resulting in smaller, already dried crystals following larger, undried crystals throughout the drying process, thus limiting drying efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a vibration drying device for chemical crystal particles. This device can perform separate drying of different particle sizes during the drying process, thereby improving drying efficiency and facilitating collection after drying, thus increasing production efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A vibratory drying device for chemical crystalline particles includes a support frame, a drying disc rotatably connected inside the support frame, and fixed plates symmetrically arranged inside the drying disc. A drying inner chamber is rotatably connected to the two fixed plates. A rotating shaft is connected to one end of the drying inner chamber, and a first servo motor is connected to the other end of the rotating shaft. The first servo motor is fixed to the side of the drying disc. An inlet pipe and an outlet pipe are fixed to the top and bottom of the drying disc, respectively. Electric shut-off valves are fixed to the outside of both the inlet and outlet pipes. A vent pipe is fixed to the drying inner chamber opposite to the first servo motor, and an electric air valve is fixed to the outside of the vent pipe. A heating element is fixed inside the drying disc. A leakage hole is provided on the side of the drying inner chamber, and the internal area of ​​the drying inner chamber communicates with the external area of ​​the drying inner chamber through the leakage hole.

[0008] Furthermore, the heating element includes a heat-conducting plate fixed to the inner wall of the drying tray. The heat-conducting plates are symmetrically arranged, and each heat-conducting plate has a heating rod inside. The heating rod is annular, and all the heating rods are electrically connected to a power module, which is installed on the outside of the drying tray.

[0009] Furthermore, a first damping rod and a second damping rod are respectively provided at both ends of the drying tray. The first damping rod is fixedly connected to the drying tray, and the second damping rod abuts against the drying tray. A first horizontal plate is fixed to the end of the first damping rod away from the drying tray, and a second horizontal plate is fixed to the end of the second damping rod away from the drying tray. A vibration motor is also screwed and installed on the side of the drying tray.

[0010] Furthermore, a drive shaft is rotatably connected to the bottom of the first horizontal plate. One end of the drive shaft is connected to a second servo motor mounted on the bracket, and the other end of the drive shaft is rotatably connected inside the bracket.

[0011] Furthermore, a fixing rod is fixed to the side of the first horizontal plate. The fixing rod slides along the inside of the bracket. A semi-circular groove is provided inside the bracket for the fixing rod to move.

[0012] Furthermore, a cylinder is connected to the top of the second horizontal plate, and the cylinder is mounted on the bracket.

[0013] Furthermore, an insulation cotton board is adhered to the inner wall of the drying tray, and the same insulation cotton board is adhered to the opposite sides of the two fixing plates.

[0014] Furthermore, a spiral rod is fixed to the outside of the drying inner liner, and several spiral rods are arranged along the circumference of the drying inner liner.

[0015] In summary, the beneficial technical effects of this utility model are as follows:

[0016] 1. The drying inner liner is driven to rotate by a first servo motor. At the same time, a spiral rod is fixed on the outside of the drying inner liner. Several spiral rods are arranged along the circumference of the drying inner liner. As the drying inner liner rotates, the particles entering the drying inner liner can rotate and pass back and forth between the inside and outside of the drying inner liner. Due to the continuous leakage, there is a height difference during the movement, which increases the contact area with heat and increases the contact time with heat. This allows smaller particles to be dried separately. At the same time, as the drying inner liner rotates, the external spiral rods act as stirring rods to stir the particles, which can also increase the heat contact area. Thus, the drying efficiency of particles in both areas is improved.

[0017] 2. The pressure relief pipe can control the opening and closing of the electric gas valve at any time during the heating process to avoid damage to the drying tray due to excessive internal pressure.

[0018] 3. The drying tray can be rotated and laid flat for easy maintenance or cleaning. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a vibratory drying device for chemical crystallizing particles, including a support 1, a drying disc 2 rotatably connected inside the support 1, a fixing plate 3 fixed inside the drying disc 2, the fixing plates 3 being symmetrically arranged, a drying inner liner 4 rotatably connected inside the two fixing plates 3, a rotating shaft 5 connected to one end of the drying inner liner 4, a first servo motor 6 connected to the other end of the rotating shaft 5, the first servo motor 6 being fixed to the side of the drying disc 2, a feed pipe 7 and a discharge pipe 8 fixed to the top and bottom of the drying disc 2 respectively, an electric shut-off valve 9 fixed to the outside of both the feed pipe 7 and the discharge pipe 8, a vent pipe 10 fixed to the side of the drying inner liner 4 opposite to the first servo motor 6, an electric air valve 11 fixed to the outside of the vent pipe 10, a heating element fixed inside the drying disc 2, and a leakage hole 12 provided on the side of the drying inner liner 4, the internal area of ​​the drying inner liner 4 communicating with the external area of ​​the drying inner liner 4 through the leakage hole 12.

[0028] Specifically, the heating element includes a heat-conducting plate 13 fixed to the inner wall of the drying tray 2. The heat-conducting plates 13 are symmetrically arranged, and each heat-conducting plate 13 has a heating rod 14 inside. The heating rod 14 is annular, and all the heating rods 14 are electrically connected to a power module 15. The power module 15 is installed on the outside of the drying tray 2. The heating rod 14 is a conventional single-ended heating tube, which is made into an annular shape and installed inside the heat-conducting plate 13. At the same time, all the single-ended heating tubes are connected in series and powered by the power module 15. The inner wall of the drying tray 2 is bonded with a heat-insulating cotton board 26, and the two fixing plates 3 are bonded with the same heat-insulating cotton board 26 on opposite sides. Thus, the heat emitted by the heating rods 14 stays inside the drying tray 2.

[0029] In this embodiment, the drying tray 2 is double-layered and divided by an inner drying liner. Since the inner drying liner is provided with a perforation 12, chemical crystal particles larger than the perforation 12 will remain in the area between the drying tray 2 and the inner drying liner, while chemical crystal particles smaller than the perforation 12 can enter the interior of the inner drying liner.

[0030] The drying inner liner is driven to rotate by the first servo motor 6. At the same time, a spiral rod 27 is fixed on the outside of the drying inner liner. Several spiral rods 27 are arranged along the circumference of the drying inner liner. As the drying inner liner rotates, the particles entering the drying inner liner can rotate and pass back and forth between the inside and outside of the drying inner liner. Due to the continuous leakage, there is a height difference during the movement, which increases the contact area with heat and increases the contact time with heat. This allows smaller particles to be dried separately. At the same time, as the drying inner liner rotates, the external spiral rods 27 act as stirring rods to stir the particles, which can also increase the heat contact area. Thus, the drying efficiency of particles in both areas is improved.

[0031] Based on this, a vibration motor 20 is installed. Specifically, a first damping rod 16 and a second damping rod 17 are respectively installed at both ends of the drying tray 2. The first damping rod 16 is fixedly connected to the drying tray 2, and the second damping rod 17 abuts against the drying tray 2. A first horizontal plate 18 is fixed to the end of the first damping rod 16 away from the drying tray 2, and a second horizontal plate 19 is fixed to the end of the second damping rod 17 away from the drying tray 2. The vibration motor 20 is also screwed and installed on the side of the drying tray 2. When the vibration motor 20 is turned on, the entire drying tray 2 vibrates. Since the drying tray 2 is limited in the horizontal direction, in the vertical direction, through the structure of the first damping rod 16 and the second damping rod 17, combined with the vibration generated by the vibration motor 20, a small reciprocating motion can be generated in the vertical direction, thereby shaking the particles inside in the vertical direction. Combined with the rotation of the drying inner liner, the particles will also move along the diameter of the drying tray 2 during the rotation process, further improving the drying efficiency.

[0032] The bottom of the first horizontal plate 18 is rotatably connected to a drive shaft 21. One end of the drive shaft 21 is connected to a second servo motor 22 mounted on the bracket 1, and the other end of the drive shaft 21 is rotatably connected inside the bracket 1. A fixing rod 23 is fixed on the side of the first horizontal plate 18. The fixing rod 23 slides along the inside of the bracket 1. A semi-circular groove 24 is provided inside the bracket 1 for the fixing rod 23 to move. The top of the second horizontal plate 19 is connected to a cylinder 25, which is mounted on the bracket 1.

[0033] The working principle of this utility model is as follows: Open the electric shut-off valve 9 on the feed pipe 7 to add crystalline particles into the feed pipe 7. After the crystalline particles are added, close the electric shut-off valve 9, while keeping the electric shut-off valves 9 on the discharge pipe 8 and the vent pipe 10 closed. Turn on the first servo motor 6. As the drying inner chamber rotates, particles of different sizes can be separated and dried through the vent hole 12 during the drying process. Power is supplied by the power module 15, and the heating rod 14 begins to heat the internal area of ​​the drying tray 2. During the heating process, the first servo motor 6 is kept in motion. After drying is completed, open the electric shut-off valve 9 on the discharge pipe 8 to collect the material.

[0034] The pressure relief pipe is designed to control the opening and closing of the electric air valve 11 at any time during the heating process, so as to avoid damage to the drying tray 2 due to excessive increase in internal pressure.

[0035] Meanwhile, a drive shaft 21 driven by a second servo motor 22 is provided at the bottom of the first horizontal plate 18. This shaft can be used to drive the rotation of the drying tray 2. When rotating, the cylinder 25 is opened, driving the second damping rod 17 to no longer contact the side of the drying tray 2. At the same time, the fixing rod 23 on the side of the first horizontal plate 18 slides along the semi-circular groove 24 to keep the rotation of the drying tray 2 stable. This allows the drying tray 2 to be laid flat, facilitating subsequent maintenance or cleaning. When in use, the drying tray 2 is driven to a vertical position again, and the cylinder 25 is opened, causing the second damping rod 17 to contact the side of the drying tray 2 again.
