Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of high-pressure vessel sight glass cleaning technical field, specifically to a kind of dirty scraping mechanism for high-pressure vessel sight glass. BACKGROUND

[0002] The dirty cleaning of the sight glass of the high-pressure pressure vessel in the prior art has been a problem difficult to solve in the industry, and the main reason is that the design and installation difficulty of the sight glass to be wiped and scraped to remove dirt under medium-high pressure and the guarantee of safety and reliability.

[0003] In the prior art, the dirty cleaning mechanism of most sight glasses achieves the effect of cleaning dirt by opening a hole in the sight glass and setting a rotating scraper, as mentioned in patents CN211217690U and CN210456019U, which all need to open a hole in the sight glass. These methods can be well applied in low-pressure containers, but for medium-high pressure applications, the sight glass opening will significantly reduce its structural strength and increase the risk of sight glass breakage due to the greater pressure and bending stress that the sight glass glass bears, making it difficult to be applied in medium-high pressure applications.

[0004] The self-cleaning device mentioned in patent CN221453506U does not open a hole in the sight glass, but its scraping drive mechanism has a large length size, and the pressure during scraping enters the motor, screw and shell side, which cannot achieve online dirt removal, and requires high strength for the shell and the support strength of the two sealing plates, so it is obviously not suitable for application in medium-high pressure pressure vessel applications.

[0005] In addition, the shaft needs to extend from the outside of the sight glass to the inside of the container side of the sight glass to drive the scraper. In theory, the container pressure will generate an axial force on the shaft. Under low pressure, the axial force generated by the shaft due to air pressure is small and can be ignored, but when applied in a medium-high pressure environment, the axial force generated at the shaft can reach a considerable magnitude. For example, the shaft diameter is φ15, the container pressure is 15MPa, and the axial force generated at the shaft can reach 270kgf. Under the action of this force, the scraper mechanism is difficult to work normally or even damage the scraper or the sight glass. UTILITY MODEL CONTENTS

[0047] The utility model discloses a kind of dirt scraping piece mechanisms for high pressure vessel sight glass, mainly applied in high pressure pressure vessel field.

[0048] In the embodiment, the high pressure pressure vessel design pressure is 1.6MPa (including) to 40MPa (including) application scenario.

[0049] A kind of for high pressure vessel sight glass, mainly including pivot 5, scraper 1, glass 2, glass 2 is installed on the mounting seat 6 connected to high pressure vessel 10, glass 2 is installed on mounting seat 6, and is compressed by flange 3.

[0050] Further, in actual use, static sealing device, such as sealing gasket, is arranged between mounting seat 6, glass 2 and flange 3.

[0051] The pivot 5 is installed on the mounting seat 6, and two groups of sealing devices 11 are arranged therebetween, and the pivot 5 can rotate and axially move relative to the mounting seat 6.

[0052] The inner diameters of the two groups of sealing devices 11 are equal in size, so that the axial force of the container pressure on the pivot 5 is avoided.The sealing device 11 comprises a guide cylinder installed on the mounting seat 6 and a sealing ring arranged between the guide cylinder and the pivot 5.

[0053] The pivot 5 is rigidly connected to the scraper arm 4, the scraper arm 4 is connected to the scraper 1 through a hinge, and the rotation of the pivot 5 can realize the swinging and scraping of the scraper 1 on the glass 2.

[0054] The mounting seat 6 is provided with a spring guide cylinder 8, and the adjusting cap 9 is connected to the spring guide cylinder 8 through thread connection or flange 3 connection, the relative position between the adjusting cap and the spring guide cylinder 8 can be adjusted to adjust the compression amount of the spring 7, and the elastic force is applied to the pivot 5, and finally the contact force between the scraper 1 and the glass 2 is adjusted.

[0056] For easy installation, the mounting seat 6 and the spring 7 guide cylinder are connected through flange 3, and are provided with sealing rings.

[0057] As an option, the two groups of sealing devices 11 arranged between the mounting seat 6 and the pivot 5 are detachable flange 3 type, and are rigidly connected and sealed through flange 3 screws and sealing rings.

[0058] In actual use, the scraper 1 mechanism is installed on the mounting seat 6 of the pressure vessel, and the two are rigidly connected through screws or strong clamps, and are provided with sealing rings therebetween.

[0059] When the container is working, if the glass 2 is not cleaned, the glass 2 will be blocked by the volatilized dirt, affecting the observation of the working state of the material in the container.

[0060] The scraper 1 is arranged on the pressure side of the glass 2, the scraper 1 can swing around the pivot 5, and the swinging range of the scraper 1 can be controlled by controlling the swinging range of the pivot 5, such as Figure 2As shown, the wiper 1 is in the middle state and the two limit stroke states respectively.

[0066] Further, the utility model is additionally provided with cooling measures, such as a circulating water cooling channel on the mounting seat 6, which can expand the temperature application range of the mechanism.

[0067] Further, 1 to several layers of glass 2 are additionally provided outside the flange 3, and cooling circulating water can be introduced between the glass 2 interlayers to increase the cooling effect, or the water pressure or air pressure between the glass 2 layers is controlled to achieve the effect of gradually reducing the pressure from the inside to the outside, which can further improve the temperature and pressure application range of the mechanism.

[0068] Compared with the prior art, the biggest advantage of the utility model and the prior art is that the rotating shaft 5 for driving the wiper 1 has an open structure at both ends. Further, the two ends of the rotating shaft 5 are outside the pressure environment, and the container pressure will not generate an axial force on the rotating shaft 5, so the contact force between the wiper 1 and the glass 2 can be accurately adjusted without being affected by the container pressure P, which is an advantage that the industry does not have at present, and can solve the pain point of online wiping and dirt removal of the sight glass of the high-pressure container 10.
