Description

Technical Field

[0001] This utility model relates to the technical field of beam scrapers, and in particular to a structure of a fixed-aperture water-cooled beam scraper for vacuum applications. Background Technology

[0002] In existing scraper structures, the water-cooling structure of the scraper mainly consists of a water-cooling ring wound around a stainless steel tube, or an adjustable scraper plate as the main body, with the water-cooling ring placed around the scraper plate.

[0003] This structure does not effectively reduce the heat generated by the scraper plate during the scraping process in a short time. Moreover, when the scraping aperture changes significantly, the water cooling ring cannot change accordingly. It can only change the aperture within a limited space, and the water cooling efficiency is low, while the adjustment structure is costly. Utility Model Content

[0004] In view of the above-mentioned problems of existing scrapers, the aim is to provide a vacuum fixed-aperture water-cooled scraper structure that improves water cooling efficiency and reduces cost.

[0005] The specific technical solution is as follows:

[0006] A fixed-aperture water-cooled scraper structure for vacuum applications includes: a main body and a scraper plate, wherein the main body has an opening, and the scraper plate is coaxially installed in the opening;

[0007] The main body has a cooling channel inside, which surrounds the outside of the hole. The main body has a coolant inlet and a coolant outlet that communicate with the cooling channel.

[0008] As a further improvement and optimization of this solution, the main body is made of oxygen-free copper.

[0009] As a further improvement and optimization of this solution, an inlet connector is connected to the coolant inlet, and an outlet connector is connected to the coolant outlet.

[0010] As a further improvement and optimization of this solution, the inlet connector and the coolant inlet, and the outlet connector and the coolant outlet are all connected by vacuum brazing.

[0011] As a further improvement and optimization of this solution, the cooling channel includes: a plurality of liquid cooling channels, which are distributed along the axial direction of the orifice, and adjacent liquid cooling channels are connected by at least one connecting channel, and the coolant inlet and the coolant outlet are respectively connected to one of the liquid cooling channels.

[0012] As a further improvement and optimization of this solution, the liquid cooling channels are arranged in a square structure.

[0013] As a further improvement and optimization of this solution, the connecting channel is parallel to the axial direction of the hole.

[0014] As a further improvement and optimization of this solution, it also includes: two vacuum connecting pipes, one end of each of the two vacuum connecting pipes being connected to both ends of the orifice, and the other end of each being connected to a vacuum slip flange.

[0015] As a further improvement and optimization of this solution, a first assembly groove is coaxially provided at one end of the hole, a second assembly groove is coaxially provided at the bottom of the first assembly groove, and a third assembly groove is coaxially provided at the other end of the hole.

[0016] One end of one of the vacuum connecting tubes is coaxially connected to the first assembly groove, and one end of the other vacuum connecting tube is coaxially connected to the third assembly groove.

[0017] The scraper plate is coaxially mounted on the bottom of the second assembly slot.

[0018] As a further improvement and optimization of this solution, the scraper plate is made of tungsten.

[0019] The positive effects of the above technical solution compared with the existing technology are:

[0020] In this invention, coolant (such as water) can be pumped into the cooling channel through the coolant inlet and out through the coolant outlet. When the coolant flows in the cooling channel, it will exchange heat with the heat generated by the scraping beam in the hole, which greatly improves the water cooling efficiency. At the same time, there is no need to adjust the hole diameter multiple times. Only the beam diameter to be scraped needs to be calculated to realize the one-time forming process of the scraping plate, reducing production costs. Attached Figure Description
