Description

Technical Field

[0001] This utility model relates to the field of automated machinery, and in particular to a dustproof observation window for use in vacuum dust environments. Background Technology

[0002] When the nano-silicon powder production equipment is running, it is necessary to set up an observation window to observe the situation inside the furnace. Because the equipment is in a vacuum dust mixing environment, the quartz glass of an ordinary observation window will soon be covered by dust, making it impossible to observe effectively and affecting its use.

[0003] This invention provides an integrally sealed observation window with a dustproof partition. The cleanliness of the quartz glass is ensured by opening and closing the dustproof partition, which meets the requirements for observation in a vacuum dust environment. Utility Model Content

[0004] The main purpose of this invention is to provide a dustproof observation window for use in vacuum dust environments.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dustproof observation window for a vacuum dust environment includes a sealing base and a sealing cover. The sealing cover is fixedly installed on the sealing base. The sealing base and the sealing cover have corresponding observation windows. An installation groove is formed between the sealing base and the sealing cover. A dustproof partition is slidably installed in the installation groove. An opening is formed on one side of the installation groove, which extends to the outside of the sealing base. A partition rod is slidably installed in the opening and is fixedly connected to the dustproof partition. An observation window flange is fixedly installed on the outside of the observation window of the sealing cover. The observation window flange covers and fixes a quartz glass plate at the observation window.

[0007] Furthermore, a dustproof sleeve is fixedly installed in the mounting groove, and the dustproof sleeve fits tightly against the dustproof partition.

[0008] Furthermore, the dustproof sleeve is made of POM plastic to provide minimal deformation space.

[0009] Furthermore, a guide sleeve is fixedly installed at the end of the opening. The guide sleeve has a guide hole and is slidably fitted onto the outer ring surface of the partition rod through the guide hole. A sealing ring is provided between the guide sleeve and the sealing base.

[0010] Furthermore, the guide hole of the guide sleeve is an irregular circle, and the cross-sectional shape of the guide rod is the same as the shape of the guide hole.

[0011] Furthermore, a sealing ring is fixedly provided between the quartz glass and the observation window flange and sealing cover plate.

[0012] Furthermore, a small gap is provided between the dustproof base and the dustproof partition, and a small gap is also provided between the dustproof partition and the dust cover. The gap between the dustproof partition, the dustproof cover, and the sealing base is 0.1mm.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention reduces the time dust is in contact with the quartz glass and prolongs the clear viewing experience by closing the partition when not observing, opening the partition when observing, and closing the partition after observation. Attached Figure Description

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0020] See Figure 1-2 As shown, a dustproof observation window for a vacuum dust environment includes a sealing base 1 and a sealing cover 2. The sealing cover 2 is fixedly installed on the sealing base 1. The sealing base 1 and the sealing cover 2 are provided with observation windows in corresponding positions. An installation groove is opened between the sealing base 1 and the sealing cover 2. A dustproof partition 5 is slidably installed in the installation groove. An opening is opened on one side of the installation groove, and the opening extends to the outside of the sealing base 1. A partition rod 6 is slidably installed in the opening. The partition rod 6 is fixedly connected to the dustproof partition 5. An observation window flange 3 is fixedly installed on the outside of the observation window of the sealing cover 2. The observation window flange 3 covers and fixes a quartz glass plate 8 at the observation window.

[0021] A guide sleeve 7 is fixedly installed at the end of the opening. The guide sleeve 7 has a guide hole. The guide sleeve 7 is slidably sleeved on the outer ring surface of the partition rod 6 through the guide hole. A sealing ring 9 is provided between the guide sleeve 7 and the sealing base 1.

[0022] The guide hole of the guide sleeve 7 is an irregular circle, and the cross-sectional shape of the guide rod is the same as the shape of the guide hole.

[0023] A sealing ring 9 is fixedly provided between the quartz glass 8, the observation window flange 3, and the sealing cover plate 2.

[0024] The dustproof observation window body is formed by the sealing base 1, sealing cover 2, observation window flange 3, quartz glass 8, and sealing ring 9. The sealing ring 9 ensures vacuum sealing at all points. A dustproof sleeve 4 is installed inside, which provides a small deformation space for the POM plastic material to prevent the dustproof partition 5 from being clamped when opened / closed. The dustproof partition 5 and the partition rod 6 are connected by screws. The partition rod 6 extends out of the observation window body and is restricted in axial direction by the guide sleeve 7. Axial sealing is achieved by the sealing ring 9.

[0025] The gap A between the dustproof partition 5, the dustproof sleeve 4, and the sealing base 1 is set to 0.1 mm. This gap can ensure that the dustproof partition 5 can open / close smoothly and prevent dust from seeping in. Because of the vacuum environment, this gap is set to balance the pressure of the vacuum dust chamber 10 and the observation window body.

[0026] When using, such as Figure 1 As shown, the dustproof partition 5 is closed, isolating the vacuum dust environment to ensure the cleanliness of the quartz glass 8. No observation is performed at this time.

[0027] like Figure 2 As shown, during observation, pulling the partition rod 6 outward moves the dustproof partition 5 to open the observation channel. At this time, there is no obstruction between the quartz glass 8 and the vacuum dust chamber 10, allowing for effective observation. After observation, pushing the partition rod 6 inward moves the dustproof partition 5 to close the observation channel, restoring it to a closed state. By reducing the time the quartz glass 8 is exposed to the vacuum dust environment, the clear viewing effect is extended.

[0028] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
