Description

Technical Field

[0001] This utility model relates to the field of electronic powder drying technology, specifically to an electronic powder hot air drying device. Background Technology

[0002] "Electronic powder" is a broad category, generally referring to various high-performance ceramic powders used in the manufacture of electronic components (such as MLCC multilayer ceramic capacitors, varistors, magnetic components, etc.). Drying these powders is a crucial step in the production process, directly affecting the performance and yield of the final product. Hot air drying equipment is required for the drying of electronic powders.

[0003] Patent application number 202420444499.4 discloses a hot air drying device. One end of the air supply pipe located inside the drying tank is rotatably connected to the air conveying pipe. The air supply pipe and the air conveying pipe are connected. A drying air outlet blade is fixedly connected to one side of the air conveying pipe. The bottom of the drying air outlet blade is connected to the bottom end of the air conveying pipe. A silicone scraper is fixedly connected to the side of the drying air outlet blade near the inner wall of the drying tank.

[0004] The aforementioned hot air drying device uses an air outlet pipe to discharge water vapor. However, the air convection generated between the air inlet pipe and the air outlet pipe causes the powder to float in the air and be discharged from the air outlet pipe. It is difficult to control the discharge of the powder during the drying process, resulting in the powder being carried out by the air after drying, and the drying effect is poor.

[0006] In view of the problems existing in the above and / or existing electronic powder hot air drying devices, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a hot air drying device for electronic powder. When drying electronic powder, the breathable mesh and filter bag intercept and block the electronic powder during the drying process, which greatly reduces the escape of electronic powder with the air and improves the drying effect of electronic powder.

[0008] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0009] A hot air drying device for electronic powder, comprising:

[0010] A drying cylinder, one end of which is integrally formed with a hot air channel, and a drive mechanism is installed on the drying cylinder. A finned heater and a fan are respectively installed in the hot air channel.

A filter bag with a conical structure is fixed to the side wall of the air outlet channel. A connecting rod is fixed at the center of the filter bag. Multiple rigid fixing rods that are fixed to the inner wall of the air outlet channel are welded to the outer wall of the connecting rod.

[0012] A rotating cylinder is embedded in a drying cylinder, and bearings connected to the drying cylinder are fixed at both ends of the rotating cylinder. A toothed ring is fixedly sleeved at the center of the rotating cylinder. Electronic powder storage boxes are installed in a ring array in the rotating cylinder through a support mechanism. A breathable mesh with a pore size smaller than that of the electronic powder is bonded and fixed to the inner wall of the electronic powder storage box.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: When drying electronic powder, the fan draws in external air, which is heated by the finned heater and flows in the rotating drum. During the flow, the hot air dries the electronic powder in the electronic powder storage box through the breathable mesh. The breathable mesh can reduce the escape of electronic powder with the air flow. At the same time, the cone-shaped filter bag in the air outlet channel intercepts a small amount of escaped electronic powder. Meanwhile, the airflow blows the electronic powder on the surface of the cone-shaped filter bag toward the end plate, avoiding the accumulation of electronic powder on the surface of the filter bag and causing blockage. The breathable mesh and filter bag intercept and block the electronic powder during drying, greatly reducing the escape of electronic powder with the air and improving the drying effect of electronic powder.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0033] This utility model provides a hot air drying device for electronic powder. When drying electronic powder, the breathable mesh 501 and filter bag 304 intercept and block the electronic powder during drying, which greatly reduces the escape of electronic powder with the air and improves the drying effect of electronic powder.

[0034] Figures 1-6 The diagram shown is an overall structural schematic of one embodiment of the electronic powder hot air drying device of this utility model. Please refer to [link / reference]. Figures 1-6 This embodiment of an electronic powder hot air drying device includes:

[0035] The drying cylinder 100 has a hot air channel 200 integrally formed at one end, and a drive mechanism is installed on the drying cylinder 100. A finned heater 201 and a fan 203 are respectively installed in the hot air channel 200.

[0036] End plate 300 is detachably fixed to the other end of drying cylinder 100, and an air outlet channel 301 is fixed on the end plate 300. A filter bag 304 with a conical structure is fixed to the side wall of the air outlet channel 301. A connecting rod 303 is fixed at the center of the filter bag 304. Multiple rigid fixing rods 302 that are fixed to the inner wall of the air outlet channel 301 are welded to the outer wall of the connecting rod 303.

[0037] A rotating cylinder 400 is embedded in the drying cylinder 100, and bearings 401 connected to the drying cylinder 100 are fixed at both ends of the rotating cylinder 400. A toothed ring 402 is fixedly sleeved at the center of the rotating cylinder 400. An electronic powder storage box 500 is installed in the rotating cylinder 400 in a ring array through a support mechanism. A breathable mesh 501 with a pore size smaller than that of the electronic powder is bonded and fixed to the inner wall of the electronic powder storage box 500. A cone-shaped filter bag 304 in the air outlet channel 301 intercepts a small amount of escaped electronic powder. At the same time, the airflow blows the electronic powder on the surface of the cone-shaped filter bag 304 toward the end plate 300, avoiding the accumulation of electronic powder on the surface of the filter bag 304 and causing blockage. The breathable mesh 501 and the filter bag 304 intercept and block the electronic powder during drying, greatly reducing the escape of electronic powder with the air and improving the drying effect of electronic powder.

[0038] Combination Figures 1-6 The specific operation of the electronic powder hot air drying device of this embodiment is as follows: When drying electronic powder, the fan 203 draws in external air, which is heated by the finned heater 201 and flows in the rotating cylinder 400. During the flow, the hot air dries the electronic powder in the electronic powder storage box 500 through the breathable mesh 501. The breathable mesh 501 can reduce the escape of electronic powder with the air flow. At the same time, the cone-shaped filter bag 304 in the air outlet channel 301 intercepts a small amount of escaped electronic powder. Meanwhile, the airflow blows the electronic powder on the surface of the cone-shaped filter bag 304 toward the end plate 300, avoiding the accumulation of electronic powder on the surface of the filter bag 304 and the blockage. The breathable mesh 501 and the filter bag 304 intercept and block the electronic powder during drying, greatly reducing the escape of electronic powder with the air and improving the drying effect of electronic powder.

[0039] Both ends of the drying cylinder 100 are fixedly fitted with support frames 101, and the ends of the drying cylinder 100 and the end plate 300 are provided with flanges. Bolts and nuts threaded onto the bolts are installed between the two flanges. When the nuts are unscrewed, the end plate 300 is separated from the drying cylinder 100. After removing the end plate 300, the electronic powder storage box 500 is pulled by the handle to slide out of the mounting frame 403. A fan 203 is embedded and fixed in the center of the hot air channel 200, and a dustproof plate 202 is fixed to the side wall of the hot air channel 200. The support mechanism includes mounting frames 403 that are welded and fixed to the inner wall of the rotating cylinder 400 in a ring structure, and connecting rods integrally formed between multiple mounting frames 403. Multiple receiving cavities 404 are opened in a ring array on the mounting frames 403. Multiple connecting rods support different positions of the electronic powder storage box 500. The electronic powder storage box 500 matches the receiving cavity 404. A sealing plate 502 is installed on the side wall of the electronic powder storage box. A handle is fixed to the side wall of the sealing plate 502. Both ends of the sealing plate 502 are equipped with knob bolts 503. Both knob bolts 503 pass through the sealing plate 502 and are threaded into the electronic powder storage box 500. After the electronic powder storage box 500 is removed from the mounting bracket 403, the knob bolts 503 are unscrewed and the sealing plate 502 is removed. After the sealing plate 502 is removed, the electronic powder in the electronic powder storage box 500 is poured out and new electronic powder to be dried is poured in. When drying the electronic powder, the storage volume in the electronic powder storage box 500 is less than three-quarters full, so that the electronic powder inside the electronic powder storage box 500 can be flipped during the rotation of the electronic powder storage box 500, so that the electronic powder in different positions corresponds to the breathable mesh 501. For this purpose, please refer to [link / reference needed]. Figures 1-6 In this embodiment, a motor 102 is fixedly installed at the top of the drying cylinder 100. Both ends of the motor 102 are equipped with bases fixed to the drying cylinder 100. A through groove 104 is opened at the top of the drying cylinder 100. A gear 103 is fixedly installed on the shaft of the motor 102. The gear 103 is embedded in the through groove 104, and the bottom end of the gear 103 passes through the through groove 104 and meshes with the gear ring 402.
