A continuous furnace with convenient furnace arrangement

Abstract

The utility model relates to a continuous furnace which is convenient for furnace discharge. An upper furnace body is designed in sections along a glass traveling direction. A section of the upper furnace body with an upper furnace door is connected to a lifting motor reducer and a lifting chain. When the furnace needs to be discharged, only the part of the upper furnace body with the furnace door installed needs to be quickly lifted separately. This can prevent glass from being blocked at the furnace door and causing it to stick to the furnace, and can also reduce energy consumption and protect the upper furnace body from being damaged by high temperature. At the same time, the opening design of the upper furnace door can be reduced, so as to effectively prevent cold wind from flowing back and improve the quality of glass tempering.

Description

Technical Field

[0001] The utility model relates to the technical field of glass tempering furnaces, in particular to a continuous furnace which is convenient for furnace arrangement. Background Art

[0002] At present, the existing continuous furnace body (such as Figure 1 ) When making glass normally, the upper furnace door needs to be opened to allow the glass to pass through. The opening size of the upper furnace door is set in advance and cannot be adjusted during use. The opening size is also related to the furnace discharge. When the furnace needs to be discharged, if the upper furnace door is opened too small, the glass is easily blocked on the furnace door and difficult to discharge, resulting in sticking to the furnace and causing serious accidents. In order to solve the problem of furnace discharge in the prior art, the solution of raising the upper furnace body for furnace discharge is adopted. However, raising the upper furnace body as a whole will increase energy consumption on the one hand, and the high temperature in the furnace will easily damage the upper furnace body on the other hand; if the opening of the upper furnace door is enlarged, the cold air in the high-pressure section will easily flow back into the heating furnace body, lowering the glass temperature and affecting the quality of glass tempering; in addition, the maximum opening of the furnace door is limited, and even if it is maximized, it is still not conducive to furnace discharge. Utility Model Content

[0003] In view of the defects of the prior art, the purpose of the utility model is to provide a continuous furnace which is convenient for furnace discharge. The upper furnace body adopts a segmented design. When the furnace needs to be discharged, only the part of the upper furnace body where the furnace door is installed needs to be quickly raised to avoid glass blocking the furnace door and causing the furnace to stick. It can also reduce energy consumption and protect the upper furnace body. At the same time, the opening design of the upper furnace door can be reduced to avoid cold air backflow.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A continuous furnace with convenient furnace arrangement comprises an upper furnace body. The upper furnace body is designed in sections along the direction of glass travel, and is divided into multiple sections from one section. An upper furnace door is installed on the section of the upper furnace body located at the end of the glass travel direction, and the upper furnace body of this section can be raised independently and quickly.

[0006] Furthermore, the section of the upper furnace body where the upper furnace door is installed is defined as the upper end furnace body, and the upper end furnace body is installed on the upper furnace body through a lifting motor reducer, a lifting chain, a guide shaft, a guide sleeve, a lifting plate, and a connecting plate.

[0007] Furthermore, a connecting plate and a lifting plate are fixed on the upper end furnace body, the other end of the connecting plate is connected to a guide sleeve, the guide sleeve is arranged outside the guide shaft, the other end of the lifting plate is connected to a lifting chain, the lifting motor reducer is fixed on another section of the upper furnace body adjacent to the upper end furnace body, the output end of the lifting motor reducer is connected to the lifting chain, and the upper end furnace body is quickly lifted by the lifting chain.

[0008] In a preferred embodiment, the elevation range of the upper end furnace body is 0-500 mm.

[0009] Preferably, the length of the upper end furnace body ranges from 10 to 2000 mm.

[0010] Preferably, the upper furnace body is divided into two sections along the glass traveling direction.

[0011] Preferably, the upper furnace door can be closed or raised, and the raised height is designed to be any value between 5-30 mm.

[0012] Beneficial effect: The utility model is a continuous furnace which is convenient for furnace discharge. The upper furnace body is divided into two sections, and the section of the upper furnace body where the furnace door is installed can be quickly raised separately to meet the needs of furnace discharge. At the same time, the opening of the upper furnace door can be reduced, which not only avoids the backflow of cold air from the high-pressure section into the furnace body, but also only the upper end of the furnace body can be quickly raised when the furnace needs to be discharged, thereby reducing energy consumption and avoiding high temperature damage to equipment.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] As attached Figure 2-3 As shown, a continuous furnace for convenient furnace discharge of the utility model comprises an upper furnace body and a lower furnace body. The original upper furnace body 1 is designed in sections and divided into two parts along the direction of glass travel. The section of the upper furnace body with the upper furnace door 2 is named the upper end furnace body 3. The upper end furnace body 3 is installed on the upper furnace body 3 by a lifting motor reducer 4, a lifting chain 5, a guide shaft 6, a guide sleeve 7, a lifting plate 8, and a connecting plate 9, and can be lifted separately for convenient furnace discharge.

[0020] Specifically, a connecting plate 9 and a lifting plate 8 are fixed on the upper end furnace body 3, the other end of the connecting plate 9 is connected to the guide sleeve 7, the guide sleeve 7 is arranged outside the guide shaft 6, the other end of the lifting plate 8 is connected to the lifting chain 5, the lifting motor reducer 4 is fixed on another section of the upper furnace body 1 adjacent to the upper end furnace body 3, the output end of the lifting motor reducer 4 is connected to the lifting chain 5, and the upper end furnace body 3 is quickly lifted by the lifting chain 5, and the state after lifting is as shown Figure 3 shown.

[0021] The upper furnace body 1 can be divided into multiple sections along the glass traveling direction as needed. The section of the upper furnace body 1 where the furnace door 2 is installed, that is, the length of the upper end furnace body 3 is generally 10-2000mm, and the lifting height is 0-500mm. In this way, there is no need to lift the entire upper furnace body 1 when discharging the furnace, which can reduce energy consumption and meet the furnace discharging requirements.

[0022] The utility model designs the upper furnace body 1 in sections, which solves the problem of furnace door opening when discharging the furnace. Therefore, compared with the prior art, the utility model can reduce the design of furnace door opening, and does not need to enlarge the furnace door opening to meet the needs of discharging the furnace. When making glass normally, the opening of the upper furnace door 2 is designed to be an arbitrary value between 5-30mm, which can reduce the backflow of cold wind from the high-pressure section into the furnace body and improve the quality of glass tempering. When discharging the furnace is required, the section of the furnace body where the upper furnace door 2 is installed can be raised separately by lifting the motor reducer 4 and the lifting chain 5, and the glass can be quickly discharged to prevent the glass from blocking the door and sticking to the furnace, which is convenient for discharging the furnace.

[0023] The utility model improves the structure of the continuous furnace and designs the upper furnace body in sections. Only part of the furnace body needs to be lifted when the furnace is discharged. Compared with the prior art, it can reduce energy consumption and avoid damage to the upper furnace body caused by the high temperature in the furnace due to the overall lifting of the upper furnace body. At the same time, the furnace door opening design can be reduced (the furnace door opening in the prior art is 460mm, and the utility model is designed to be between 5-30mm to meet the requirements), thereby preventing cold water backflow to the greatest extent and ensuring the quality of glass tempering. It can be said that it kills two birds with one stone and has good application value.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
