[0001] The present disclosure relates to the technical field of isolation sand paving, and in particular, to an isolation sand paving auxiliary part and an isolation sand paving assembly. Background Art
[0002] At present, the mainstream methods for growing sapphire single crystals in the world are as follows: guided mold method, pulling method, heat exchange method and kilosynthesis method. The kilosynthesis method is conducive to growing large-size, low-defect-density, high-quality sapphire single crystals, so it has greater advantages. In the actual use of the equipment, the crucible tray and the crucible are easily connected together after high-temperature firing, so a layer of isolation sand (such as zirconium oxide sand) needs to be laid between the crucible and the crucible tray to prevent the crucible and the crucible tray from being connected together. However, in the process of laying the isolation sand, the isolation sand is usually scraped flat by manual means, and it is difficult to keep the upper surface of the isolation sand level with the crucible tray, that is, the upper surface of the isolation sand is parallel to the horizontal plane, and the isolation sand is also easy to fall into the equipment during the scraping process, which is very troublesome to clean.

[0027] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0028] In the description of the present disclosure, it should be understood that the terms "upper", "lower", "top", and "bottom" are usually defined by the "upper", "lower", "top", and "bottom" of the crucible tray 300 in a normal use state. In addition, the terms "inside and outside" refer to the inside and outside of the corresponding structural contours. In addition, the terms "first", "second", etc. are only used to distinguish one element from another element, and do not have order and importance.
[0029] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.
[0030] In order to solve the defects that the existing isolation sand 400 laid on the crucible tray 300 is difficult to lay flat and easy to fall into the inside of the equipment, the present disclosure provides an isolation sand laying auxiliary part 100 on one hand, which is used to cooperate with the scraper 200 to lay the isolation sand 400 flat on the crucible tray 300 of the sapphire single crystal furnace.
[0031] like Figures 1 to 7 As shown, the isolation sand leveling auxiliary member 100 includes a positioning portion 110, a through hole 120, and a collecting portion 130. The positioning portion 110 is used to be placed on the crucible tray 300. The positioning portion 110 has a first surface 111 and a second surface 112 opposite to each other in the vertical direction. The first surface 111 and the second surface 112 are both planes parallel to the horizontal plane. The second surface 112 is used to contact the top surface of the crucible tray 300. The through hole 120 is formed on the positioning portion 110 and penetrates the first surface 111 and the second surface 112 in the vertical direction. The aperture of the through hole 120 is set to be smaller than the diameter of the crucible tray 300. The through hole 120 is used to allow the isolation sand 400 to pass through so that the isolation sand 400 can be laid on the top surface of the crucible tray 300. The first surface 111 is used to contact the scraper 200 when the scraper 200 is scraping the isolation sand 400. The collecting portion 130 is connected to the positioning portion 110 and has a collecting groove 131 . The collecting groove 131 is located outside the through hole 120 and is configured to collect the fallen isolation sand 400 when the scraper 200 scrapes the isolation sand 400 .
[0032] Through the above technical solution, when it is necessary to lay isolation sand 400 on the crucible tray 300, the second surface 112 of the positioning portion 110 of the isolation sand leveling auxiliary component 100 can be placed on the top surface of the crucible tray 300 so that the second surface 112 is parallel to the top surface of the crucible tray 300, and the isolation sand 400 is poured into the through hole 120 to lay the isolation sand 400 on the top surface of the crucible tray 300. After the isolation sand 400 is accumulated to overflow the through hole 120, the isolation sand 400 is leveled by the scraper 200. In the process of the scraper 200 leveling the isolation sand 400, the scraper 200 contacts the first surface 111 of the positioning portion 110, and the first surface 111 plays a positioning role in the movement of the scraper 200 to ensure that the upper surface of the isolation sand 400 can be flush with the first surface 111 of the positioning portion 110, that is, parallel to the horizontal plane, thereby achieving the effect of quickly leveling the isolation sand 400. When the scraper 200 is used to scrape the isolation sand 400, the excess isolation sand 400 is scraped by the scraper 200 to the collecting portion 130 for collection, thereby preventing the isolation sand 400 from falling into the device. After the isolation sand 400 is leveled, the isolation sand leveling auxiliary member 100 can be moved vertically upward to complete the operation of laying the isolation sand 400 on the crucible tray 300.
[0033] In addition, since the aperture of the through hole 120 is smaller than the diameter of the crucible tray 300, when in use, one end of the through hole 120 can be covered by the top surface of the crucible tray 300, so that the isolation sand 400 poured from the through hole 120 will not fall from the through hole 120 to the bottom of the crucible tray 300.
[0034] Since the isolation sand 400 is used to prevent the crucible from sticking to the crucible tray 300, the isolation sand 400 can be isolation sand that can withstand a temperature of 2200° C., that is, the melting point of the isolation sand is higher than 2200° C., such as isolation sand 400 made of particles of non-metallic material. Optionally, the isolation sand 400 can be zirconia sand made of zirconium oxide.
[0035] like Figures 2 to 4 As shown, in some optional embodiments, the isolation sand leveling auxiliary component 100 also includes a protrusion 140, which protrudes from the second surface 112 in a direction away from the first surface 111, and the protrusion 140 and the second surface 112 together define a receiving groove 141 for accommodating at least a portion of the crucible tray 300, and the protrusion 140 is used to abut against the outer peripheral surface of the crucible tray 300.
[0036] The convex portion 140 and the second surface 112 are provided to jointly define a receiving groove 141, so that after the receiving groove 141 abuts against the outer peripheral surface of the crucible tray 300, the isolation sand leveling auxiliary component 100 can be fixed on the crucible tray 300 and the horizontal movement of the isolation sand leveling auxiliary component 100 is restricted, thereby limiting the position of the through hole 120 to be consistent, and further making the position of the laid isolation sand 400 consistent.
[0037] It should be noted that the protrusion 140 may be composed of one or more components, as long as the protrusion 140 and the second surface 112 can define a receiving groove 141 , and the present disclosure does not make any specific limitation on this.
[0038] In some optional embodiments, after the isolation sand leveling auxiliary component 100 is fixedly installed on the crucible tray 300 through the receiving groove 141, the through hole 120 is colinear with the axis of the crucible tray 300, that is, the through hole 120 is located exactly at the center of the crucible tray 300, so that the laid isolation sand 400 can also be located at the center of the crucible tray 300.
[0039] In some optional embodiments, the convex portion 140 may be a side wall of the collecting portion 130 close to the positioning portion 110. The convex portion 140 is set as a side wall of the collecting portion 130 close to the positioning portion 110, so that the convex portion 140 can constitute both the side wall of the receiving groove 141 and the side wall of the collecting portion 130, playing a dual-purpose role, making the structure of the isolation sand paving auxiliary component 100 more compact.
[0040] In some optional embodiments, the convex portion 140 may be a bump formed on the second surface 112, and the collecting portion 130 is located on the side of the bump away from the through hole 120. This arrangement enables the collecting groove 131 of the collecting portion 130 to have a greater depth and volume to collect more isolation sand 400.
[0041] In some optional embodiments, the end surface of the collecting portion 130 close to the first surface 111 is flush with the first surface 111, and the notch of the collecting groove 131 is flush with the first surface 111. In this way, when the scraper 200 is used to scrape off the excess isolation sand 400, the isolation sand 400 can be easily scraped into the collecting groove 131 without being interfered by the collecting portion 130.
[0042] like Figure 1 As shown, in some optional embodiments, the collecting portion 130 surrounds the positioning portion 110, and the collecting groove 131 is formed as an annular groove surrounding the through hole 120. The collecting groove 131 is set as an annular groove, so that the isolation sand 400 can be collected when the scraper 200 scrapes off the excess isolation sand 400 from any direction, thereby improving the convenience of using the isolation sand paving auxiliary component 100.
[0043] In some optional embodiments, the through hole 120 is formed as a circular hole, and the collecting groove 131 is formed as an annular groove.
[0044] Of course, in some other embodiments, the collecting groove 131 may also be a square annular groove or an annular groove of other shapes, and the present disclosure does not make any specific limitation on this.
[0045] like Figure 5 As shown, in some optional embodiments, the groove wall of the collecting groove 131 close to the through hole 120 is formed as an inclined groove wall 132, and the distance between the end of the inclined groove wall 132 close to the first surface 111 and the axis of the through hole 120 is smaller than the distance between the end of the inclined groove wall 132 away from the first surface 111 and the axis of the through hole 120. In this way, the opening of the collecting groove 131 can be closer to the through hole 120, so that the scraped isolation sand 400 can fall into the collecting groove 131 faster.
[0046] In some optional embodiments, the isolation sand leveling auxiliary component 100 is manufactured in one piece, so that the isolation sand leveling auxiliary component 100 can be easily manufactured and formed into an integral structure, which has higher strength and is easy to carry.
[0047] Based on the above-mentioned isolation sand leveling auxiliary component 100, the present disclosure provides an isolation sand leveling component in another aspect, which is used to level the isolation sand 400 on the crucible tray 300 of the sapphire single crystal furnace, and the isolation sand leveling component includes a scraper 200 and the above-mentioned isolation sand leveling auxiliary component 100. By scraping the scraper 200 on the first surface 111 of the isolation sand leveling auxiliary component 100, the excess isolation sand 400 can be scraped off, and the isolation sand 400 can achieve a leveling effect.
[0048] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0049] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0050] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
