Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of kilns, and more specifically to a roll-up fire-blocking kiln. Background Art
[0002] A kiln is a heating equipment used in industrial production, and is widely used in metallurgy, chemical industry, building materials, ceramics, glass, electronics, food and other industries. A direct cooling section and a slow cooling section are provided in the kiln to cool the product after firing; the slow cooling section may use a spray gun or other heating equipment to maintain or slightly increase the temperature to achieve a specific heat treatment effect or prevent defects such as cracks in the product during the cooling process; the slow cooling section is an area with a relatively high temperature and a slow cooling speed, while the direct cooling section refers to an area where a cooling medium (such as water or air) is directly used to quickly reduce the temperature of the product. In order to maintain the respective processing temperatures of the slow cooling section and the direct cooling section, a fire baffle is usually used to isolate the slow cooling section from the direct cooling section. This design helps to accurately control the cooling process and ensure that the product achieves the expected physical properties during the cooling process.
[0003] In current kilns, the height of the fire baffle is adjusted manually to adjust the height of the passageway between the slow cooling section and the direct cooling section. Most of the fire baffles currently used in kilns are integrated structures, and the height of the passage cannot be flexibly adjusted during the operation of the kiln. However, during the transportation of materials in the kiln, abnormal conditions such as height abnormalities or accumulation may occur. In this case, the height of the materials will be higher than the height of the passageway, resulting in the inability of the materials to safely pass through the fire baffle, causing the passageway to be blocked; if not handled in time, the next row of materials will also be unable to pass through and will be repeatedly accumulated, aggravating the blockage and creating safety hazards. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings and deficiencies in the prior art and to provide a roll-up fire-blocking kiln; the kiln can not only achieve temperature isolation between the slow cooling section and the direct cooling section, but also can cope with the situation of abnormal material height or accumulation, flexibly adjust the passage height of the passage opening, ensure the safe passage of materials, avoid material accumulation, reduce production interruptions or efficiency reduction caused by material accumulation and blockage, and improve the safety of kiln operation.

[0006] The utility model kiln adopts a roll-up fire-blocking structure between the slow cooling section and the direct cooling section, and the fire-blocking plate is divided into multiple layers of plates, which are connected by hinges to achieve a movable lower layer. When there is no abnormality in the material, the roll-up fire-blocking plate is in a vertical downward state as a whole under the action of its own gravity;

This not only ensures the safe passage of the current material and avoids the accumulation of materials in front of the fire baffle, but also avoids affecting the passage of the rear material, reducing production interruptions or efficiency reductions caused by material accumulation and blockage.

The rollable fire damper and the fire damper bracket adopt a simple structural method to achieve height adjustment, which is easy to implement.
[0009] Preferably, the fire stop bracket is respectively provided with mounting holes 2 that match the mounting positions of the rollable fire stop plates; screw connectors are arranged in the mounting holes 1 and 2 to fix the rollable fire stop plates to the fire stop bracket.

[0011] Preferably, the articulated member is a hinge; and the rollable fire baffle has hinges between two adjacent layers of the plate body to achieve rotatable connection.
[0012] Preferably, an elastic element is used between two adjacent layers of plate bodies to achieve flexible turning.

[0014] Preferably, a handle is provided on the top of each rollable fire baffle.
[0015] Preferably, an installation gap is provided above the passage opening between the slow cooling section and the direct cooling section of the kiln; each rollable fire baffle extends from the installation gap into the passage opening between the slow cooling section and the direct cooling section of the kiln.
