Description

Technical Field

[0001] This utility model relates to the field of continuous melting furnace production technology for quartz products, specifically to a furnace mouth insulation device for continuous melting production of quartz tubes. Background Technology

[0002] The continuous melting production of quartz products requires extremely high furnace opening temperatures, which directly affect the forming of the tubes and thus the product quality. Furthermore, the continuous melting furnace process generates silicon oxides of various shapes and sizes. Personnel must perform regular cleaning operations under high-temperature conditions. When large pieces of oxide fall, there is a chance they will bounce back and cause varying degrees of damage such as impacts and scratches to the appearance of the quartz products, directly affecting their quality. Currently, continuous melting production of quartz tubes typically involves fixing an insulation sleeve below the furnace opening. However, this poses a risk of leakage under high-temperature conditions. Water leakage can contaminate the tubes, and prolonged high temperatures can cause scale buildup inside the sleeve, leading to pipe blockage and subsequent oxidation damage at the furnace opening, rendering it ineffective in protecting the furnace opening. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a furnace mouth insulation device for quartz tube continuous melting production, aiming to solve the problems existing in the background art.

[0004] To achieve the above objectives, the present invention proposes the following technical solution:

[0005] A furnace mouth insulation device for quartz tube continuous melting production includes a guide column and a support assembly; the support assembly is located on one side of the guide column and is connected to the guide column by a locking assembly provided on the guide column; an insulation assembly is provided on the support assembly; the insulation assembly is fixedly connected to the support assembly.

[0006] Furthermore, the locking assembly includes a locking sleeve and a locking bolt; the locking sleeve is sleeved on the guide post; the locking bolt is disposed on the locking sleeve and is used to fix the locking sleeve at different positions on the guide post.

[0007] Furthermore, the support assembly includes a support platform, a first support arm, and a second support arm; the support platform is fixedly connected to the locking sleeve; the first support arm and the second support arm are symmetrically arranged on both sides of the support platform; and one end is hinged to the support platform by a hinge screw, while the other end extends outward.

[0008] Furthermore, the insulation component includes a first insulation sleeve and a second insulation sleeve; both the first insulation sleeve and the second insulation sleeve are semi-circular, symmetrically arranged opposite each other, and respectively fixedly installed on the first support arm and the second support arm.

[0009] Furthermore, both the first insulation sleeve and the second insulation sleeve have grooves for installing high-temperature resistant rock wool.

[0010] The beneficial effects of the technical solution described in this utility model are as follows:

[0011] This invention fixes the insulation component to the support component and then uses a locking component to fix the support component to the guide column. The locking component can also fix the support component at different heights on the guide column, thus eliminating the need to directly fix the insulation component to the continuous melting furnace. This allows for temperature control, prevents damage due to high-temperature oxidation, and improves the service life of the insulation component. Attached Figure Description

Detailed Implementation

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings, but it is not limited thereto. Any modifications or equivalent substitutions to the technical solution of this utility model that do not depart from the spirit and scope of the technical solution of this utility model shall be covered within the protection scope of this utility model.

[0016] like Figure 1As shown, this utility model proposes a furnace mouth insulation device for quartz tube continuous melting production, which is composed of a guide column 1, a locking component 2, a support component 3 and an insulation component 4. The guide column 1 is cylindrical and welded to the lower end of the furnace body. The locking component 2 is sleeved on the guide column 1 and consists of a locking sleeve 21 and two locking bolts 22. The locking bolts 22 can fix the locking sleeve 21 at different height positions on the guide column 1, which is used to adjust the position of the support component 3 on the guide column 1 to achieve the purpose of temperature control. This can prevent the insulation sleeve from being damaged by high temperature oxidation and improve the service life of the insulation sleeve. The support assembly 3 is fixedly connected to the locking sleeve 21 and is composed of a first support arm 32, a second support arm 33 and a support platform 31. The support platform 31 is square in shape and has a semi-circular opening on the right side. The semi-circular opening is adapted to the locking sleeve 21 and is fixedly connected to the locking sleeve 21 by welding. The first support arm 32 and the second support arm 33 are symmetrically arranged and are located on both sides of the guide post 1. The right side of the first support arm 32 and the second support arm 33 are located on the support platform 31 and are hinged to the support platform 31 by hinge screws 34 to control the opening and closing degree of the two support arms to adapt to the specifications of the quartz tube continuous melting production furnace. The left side extends outward to form a support arm for supporting the heat insulation assembly 4. The insulation component 4 is fixedly installed on the support component 3 and is composed of a first insulation sleeve 41 and a second insulation sleeve 42. Both the first insulation sleeve 41 and the second insulation sleeve 42 are semi-circular and are fixedly installed on the first support arm 32 and the second support arm 33 respectively, arranged symmetrically. A groove 43 is opened on both the first insulation sleeve 41 and the second insulation sleeve 42. The groove 43 is filled with high-temperature resistant rock wool to avoid the risk of water leakage causing pipe contamination. It also avoids the insulation sleeve being directly exposed to the furnace opening and damaged by high-temperature oxidation, thus improving the service life of the insulation sleeve.

[0017] This invention fixes the insulation component 4 onto the support component 3 and the support component 3 onto the guide post 1 using the locking component 2. At the same time, the locking component 2 can fix the support component 3 at different heights on the guide post 1, thus eliminating the need to directly fix the insulation component 4 onto the continuous melting furnace. This allows for temperature control, avoids damage due to high-temperature oxidation, and improves the service life of the insulation component 4.
