Description

Technical Field

[0001] This utility model relates to a degassing device, and more particularly to a continuous material passing type vibration degassing device. Background Technology

[0002] Currently, in industries such as chemicals and electronic pastes, some pastes that require degassing are unsuitable for vacuum degassing due to the high temperature and easy evaporation of solvents. Otherwise, the solvent would easily evaporate, leading to paste denaturation. In such cases, natural settling degassing is generally used. However, natural settling degassing has problems such as long degassing time, large production space occupation, and the need for heat preservation during the long settling process, resulting in high energy consumption and low product production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a material continuous passing vibration degassing device. This device can be installed on the feeding pipeline in the material conveying process. The material continuously passes through this device to achieve degassing, which greatly improves production efficiency, stabilizes product quality, and reduces the loss of space occupation and slurry insulation energy consumption.

[0004] The technical solution to the above technical problem is: a continuous material passing type vibration degassing device, comprising N sets of vibration degassing tank assemblies. Each vibration degassing tank assembly includes a tank body and a vibration degassing component. The upper part of the tank body has a feed inlet and an exhaust return port, and the lower part of the tank body has a discharge port. Each vibration degassing component includes a vibration device and a vibration element connected to the vibration device and located inside the tank body. The vibration device is a vibration motor or an ultrasonic generator. The value of N is 1 to 10. When N > 1, the discharge port of the vibration degassing tank assembly is connected to the feed inlet of the tank body of the next set of vibration degassing tank assemblies.

[0005] A further technical solution of this utility model is: the vibration device is a vibration motor, the vibration element includes a transmission shaft and a plurality of vibration plates mounted on the transmission shaft, the vibration plates are arranged vertically on the transmission shaft, the vibration plates are composed of above-liquid vibration plates and below-liquid vibration plates, and the transmission shaft is connected to the vibration motor.

[0006] Furthermore, the uppermost liquid-based vibrating plate is umbrella-shaped.

[0007] Furthermore, the vibrating plate is a perforated plate.

[0008] Another further technical solution of this utility model is: the vibration device is an ultrasonic generator, the vibration element is a vibrating rod, and the vibrating rod is connected to the ultrasonic generator.

[0009] Furthermore, when N > 1, the feed inlet of the first set of vibrating degassing tank assemblies is higher than the exhaust return port, while the feed inlet of the remaining sets of vibrating degassing tank assemblies is lower than the exhaust return port.

[0010] Furthermore, the exterior of the tank is provided with an insulation layer.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects:

[0012] 1. Improved product quality.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Example 1: A continuous material flow type vibration degassing device, such as Figure 1 As shown, the device includes three sets of vibrating degassing tank assemblies. Each vibrating degassing tank assembly includes a tank body 1 and a vibrating degassing component. The upper part of the tank body has a feed inlet 11 and an exhaust return port 12, and the lower end of the tank body has a discharge port 13. The vibrating degassing component includes a vibrating device and a vibrating element connected to the vibrating device and located inside the tank body. The vibrating device is a vibrating motor 2. The vibrating element includes a drive shaft 3 and multiple vibrating plates 4 mounted on the drive shaft. The drive shaft 3 and the vibrating plates 4 are located inside the tank body. The top end of the drive shaft 3 extends out of the tank body and is connected to the vibrating motor 2. The vibrating plates 4 are arranged vertically on the drive shaft 3. The vibrating plates are composed of an above-liquid vibrating plate 41 and a below-liquid vibrating plate 42. The upper vibrating plate is mainly responsible for vibrating the slurry entering the tank from the feed inlet 11 to begin preliminary gas-liquid separation. Under the action of vibration, the slurry flows down along the tank wall, reducing the air bubbles inside the slurry, and is also responsible for vibrating and eliminating the air bubbles floating in the lower part of the slurry. The lower vibrating plate mainly vibrates the slurry below the liquid surface in the tank, causing the air bubbles to rise rapidly and the liquid slurry to sink, thus quickly achieving gas-liquid separation.

[0023] The tanks of the three sets of vibrating degassing tanks are connected in series, that is, the discharge port of the first set of vibrating degassing tanks is connected to the inlet of the second set of vibrating degassing tanks, and the discharge port of the second set of vibrating degassing tanks is connected to the inlet of the third set of vibrating degassing tanks.

[0024] In this embodiment, the uppermost liquid-supported vibrating plate 41 of the first set of vibrating deaerator tank components is umbrella-shaped. The tank inlet 11 is located above this umbrella-shaped liquid-supported vibrating plate, and the exhaust return port 12 is located below it. Using an umbrella-shaped vibrating plate allows the slurry to flow more evenly and smoothly down the tank wall through vibration, thus avoiding the formation of new bubbles. The inlets 11 of the second and third sets of vibrating deaerator tank components are lower than the exhaust return port 12. This design aims to reduce and avoid the impact caused by the slurry flowing down, which could lead to the formation of new bubbles.

[0025] In this embodiment, the vibrating plate 4 is a perforated plate (such as...). Figure 2 As shown, the slurry can be better degassed when passing through the mesh; and the rising bubbles can also be discharged through the mesh, increasing the bubble discharge channel.

[0026] Degassing method of Example 1: The device described in Example 1 is installed on the slurry conveying pipeline. During operation, the vibration motor is started, and driven by the vibration motor, the vibration plates inside the tank vibrate through the transmission shaft. This vibration breaks up the slurry passing through the device, achieving gas-liquid separation and degassing. Specifically, the slurry is pumped into the tank through the upper inlet. As the slurry passes through multiple stages of vibration plates, the bubbles in the slurry are vibrated, rapidly agglomerating and collapsing. Because the bubbles are lighter, they continue to rise, quickly reaching the upper part of the liquid surface. The bubbles at the liquid surface continuously collapse under the vibration of the upper vibration plates, thus achieving thorough gas-liquid separation. The heavier slurry, however, continues to sink.

[0027] The slurry, after being degassed by the first-stage vibratory degassing tank assembly, continues to enter the next-stage vibratory degassing tank assembly for further degassing. The gas after gas-liquid separation and some remaining air bubbles are discharged through the exhaust return port and flow back to the upper-stage material tank. The degassed slurry flows out from the discharge port.

[0028] Example 2: A continuous material flow type vibration degassing device, such as Figure 3 As shown, it includes three sets of vibration degassing tank assemblies. Each vibration degassing tank assembly includes a tank body 1 and a vibration degassing component. Each vibration degassing component includes a vibration device and a vibration element connected to the vibration device and located inside the tank body. The structure and series connection of the tank body 1 are the same as in Embodiment 1. The difference is that the vibration device is an ultrasonic generator 5, and the vibration element is a vibrating rod 6. The vibrating rod 6 is located inside the tank body, and the top of the vibrating rod 6 extends out of the tank body and is connected to the ultrasonic generator 5.

[0029] The degassing method of Embodiment 2 of this utility model is as follows: The device described in Embodiment 2 is installed on the slurry conveying pipeline. During operation, the ultrasonic generator 5 is started, and the ultrasonic generator drives the vibrating rod 6 to vibrate, transmitting ultrasonic waves into the slurry. The ultrasonic waves vibrate and break up the slurry passing through the device, thereby achieving gas-liquid separation and degassing.

[0030] As a variation of the various embodiments of this utility model, if the slurry needs to be kept warm, an insulation layer can be added to the outside of the tank to keep the temperature of the slurry stable.

[0031] As a variation of the various embodiments of this utility model, the number of vibration degassing tank components can be increased or decreased according to the actual situation. The tank body can be single-stage or multi-stage, that is, the number of vibration degassing tank components can be 1 group, 2 groups, 4 groups, 5 groups or more groups. Multiple groups of vibration degassing tank components are connected in series to achieve a faster and more thorough degassing effect on the slurry.

[0032] Trial Experiment 1: The device described in Embodiment 1 of this utility model is installed on a slurry conveying pipeline. The slurry conveyed in the pipeline is a ceramic slurry, which flows in the pipeline at a speed of 300L / min. The slurry enters the device described in Embodiment 1. The device has a volume of 60L, which means that the slurry residence time is 12 seconds. After the slurry continuously passes through the device described in Embodiment 1 of this utility model, the air bubbles in the slurry discharged from the outlet are basically removed, and it can be directly used in the next process without further settling and degassing.

[0033] Comparative Test 1: This utility model was not installed on the slurry conveying pipeline. Other conditions were the same as in Trial Test 1. After the slurry was conveyed to the material tank, it still needed to be left to stand for degassing. After standing for about 6 hours, the bubbles were basically removed and it could be used in the next process.

[0034] Trial Test 2: The device described in Embodiment 2 of this utility model was installed on a slurry conveying pipeline. The slurry conveyed in the pipeline was a gel, and the slurry flowed in the pipeline at a speed of 150L / min. The slurry entered the device described in Embodiment 2. The device has a volume of 60L, that is, the slurry stays in the device for 24 seconds. After the slurry continuously passed through the device described in Embodiment 2 of this utility model, the air bubbles in the slurry discharged from the outlet were basically removed, and it can be directly used in the next process without further settling and degassing.

[0035] Comparative Test 2: This utility model was not installed on the slurry conveying pipeline. Other conditions were the same as in Trial Test 2. After the slurry was conveyed to the material tank, it still needed to be left to stand for degassing. After standing for about 24 hours, the bubbles were basically removed and it could be used in the next process.
