Description

Technical Field

[0001] This utility model relates to the field of degassing equipment, and in particular to a dual-pressure degassing equipment. Background Technology

[0002] A degassing device is a piece of equipment used to remove air bubbles from various materials. It is widely used in many industries, such as the production of coatings, inks, adhesives, and emulsions. The presence of air bubbles can affect the appearance, stability, and performance of the products. Degassing devices can ensure product quality.

[0003] Traditional degassing technology involves placing the product in a sealed space and pressurizing the internal air bubbles with compressed air. Smaller bubbles shrink to invisible levels due to the pressure, and the adhesive force of the glue on the product structure further contributes to degassing. However, since it only compresses the bubbles with pressure, some bubbles will remain inside the structure. Some products that are not completely degassed cannot be reworked, inevitably leading to losses in product yield, production efficiency, and cost. Therefore, a dual-pressure degassing device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dual-pressure degassing device, which aims to improve the problem in the prior art that "traditional degassing machines only achieve degassing by applying pressure, and cannot completely remove the air bubbles present in the product".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dual-pressure degassing device, comprising a base, a support assembly provided on the inner wall of the base, a storage tank placed at the top of the support assembly, a heating ring fixedly connected to the top of the base, a sealing cover fitted onto the top of the storage tank, a sealing ring fixedly connected to the bottom of the sealing cover, a sealing sleeve installed at the top of the sealing cover, a connecting pipe installed at the right end of the sealing sleeve, a control assembly installed at the other end of the connecting pipe, the control assembly comprising a solenoid valve, the output end of the solenoid valve installed at the bottom of the connecting pipe, a vacuum pump installed at the front end of the solenoid valve, a pneumatic pump installed at the rear end of the solenoid valve, and an observation assembly provided at the top of the sealing cover.

[0006] As a further description of the above technical solution:

[0007] An electric telescopic rod is installed at the top of the base, and the top of the output shaft of the electric telescopic rod is fixedly connected to the right end of the closed cover.

[0011] The bottom end of the support platform is provided with a receiving groove, and a return spring is fixedly connected to the top end of the inner wall of the receiving groove, and the bottom end of the return spring is fixedly connected to the inner wall of the base.

[0012] As a further description of the above technical solution:

[0013] The observation component includes an observation window, which is located at the top of the closed cover.

[0014] As a further description of the above technical solution:

[0015] The observation window is provided in multiple sets, and the multiple sets of observation windows are symmetrically arranged with the center line of the closed cover as the axis of symmetry.

[0016] As a further description of the above technical solution:

[0017] A pressure gauge is installed at the top of the sealed cover.

[0018] As a further description of the above technical solution:

[0019] The right end of the electric telescopic rod is fixedly connected to a support frame, which is sleeved on the outer wall of the connecting pipe.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by setting up control components, a vacuum is first formed inside the storage tank by using a solenoid valve. Under the premise of ensuring that the product structure is not damaged, the air inside the pressure tank is emptied and heated to the set temperature.

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.

[0029] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a dual-pressure degassing device, including a base 1 for supporting the entire device. A support assembly for supporting a storage tank 3 is provided on the inner wall of the base 1. The storage tank 3 for storing products is placed at the top of the support assembly. A heating ring 2 for heating the storage tank 3 is fixedly connected to the top of the base 1. A sealing cap 4 for closing the top opening of the storage tank 3 is fitted onto the top of the storage tank 3. A sealing ring 5 for increasing the sealing between the storage tank 3 and the sealing cap 4 is fixedly connected to the bottom of the sealing cap 4. A sealing ring 5 for connecting the sealing cap 4 is installed at the top of the sealing cap 4. The sealing sleeve 7 of the cover 4 and the connecting pipe 8 is provided. The right end of the sealing sleeve 7 is equipped with a connecting pipe 8 for gas to pass through. The other end of the connecting pipe 8 is equipped with a control component 9 for controlling the extraction and inflation of gas. The control component 9 includes a solenoid valve 93. The output end of the solenoid valve 93 is installed at the bottom end of the connecting pipe 8. The front end of the solenoid valve 93 is equipped with a vacuum pump 92 for extracting excess air from the inside of the storage tank 3. The rear end of the solenoid valve 93 is equipped with a pneumatic pump 91 for injecting high-pressure gas into the inside of the storage tank 3. The top of the sealed cover 4 is provided with an observation component 6 for the operator to easily observe the degassing progress.

[0030] Reference Figure 1 - Figure 3The top of the base 1 is equipped with an electric telescopic rod 10 for moving the closed cover 4. The top of the output shaft of the electric telescopic rod 10 is fixedly connected to the right end of the closed cover 4. The closed cover 4 can be moved up and down by adjusting the electric telescopic rod 10. The support assembly includes a support platform 12 for supporting the storage bucket 3. The support platform 12 is slidably connected to the inner wall of the base 1. The support platform 12 can move vertically up and down on the inner wall of the base 1. The bottom end of the support platform 12 is provided with a receiving groove 14 for accommodating the reset spring 13. The top of the inner wall of the receiving groove 14 is fixedly connected to the reset spring 13 for moving the support platform 12 upward and resetting. The bottom end of the reset spring 13 is fixedly connected to the inner wall of the base 1. The reset spring 13 will push the support platform 12 upward at all times. The observation assembly 6 includes an observation window 62 for the operator to conveniently observe the internal condition of the storage bucket 3. The observation window 62 is located at the top of the closed cover 4.

[0031] Reference Figure 1 - Figure 3 Multiple sets of observation windows 62 are provided, and the multiple sets of observation windows 62 are symmetrically arranged with the center line of the closed cover 4 as the axis of symmetry. The multiple sets of observation windows 62 can facilitate the operator to observe the inside of the storage tank 3 from different positions. A pressure gauge 61 for measuring the internal pressure value of the storage tank 3 is installed at the top of the closed cover 4. A support frame 11 for supporting the connecting pipe 8 is fixedly connected to the right end of the electric telescopic rod 10. The support frame 11 is sleeved on the outer wall of the connecting pipe 8. By using the support frame 11 to support the connecting pipe 8, it can be prevented from bending arbitrarily.

[0032] Working principle: When degassing is required, the product is first placed inside the storage tank 3, and then the storage tank 3 is placed on top of the support platform 12. The electric telescopic rod 10 is then activated to move the sealing cover 4 downwards, covering the top of the storage tank 3. As the sealing cover 4 continues to move downwards, the storage tank 3 will press down on the support platform 12, causing it to move downwards. The support platform 12 will then compress the return spring 13, causing it to retract. Simultaneously, the support platform 12 will move into the base 1, at which point the storage tank 3 will be inserted into the heating ring 2. Then, the vacuum pump 92 and the solenoid valve 93 can be adjusted via the connecting pipe 8. The air inside the storage tank 3 is extracted, creating a vacuum inside. Simultaneously, the heating ring 2 is activated to heat the storage tank 3, activating the product. Under vacuum, the microbubbles inside the product are amplified and then burst. Because the product structure is flat, the broken bubbles will form channels to escape. After maintaining this state for a period of time, the solenoid valve 93 is adjusted, and the air pump 91 is used to inject high-pressure air into the storage tank 3 to further degas the product. By using both high and low pressure methods to degas the product, a better degassing effect can be achieved during use.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
