Description

Technical Field

[0001] This utility model relates to the field of heating furnace technology, specifically to an energy-saving heating furnace door opening control device. Background Technology

[0002] In the metallurgical industry, a heating furnace is a device (industrial furnace) used to heat materials or workpieces (usually metals) to the rolling or forging temperature. Heating furnaces are widely used in many industries, including petroleum, chemical, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, and pharmaceuticals.

[0003] During production, the opening degree of the furnace doors for steel inlet and outlet should be appropriate. Excessive opening may lead to excessive intake of cold air and leakage of internal heat, resulting in heat loss. When adjusting the furnace door opening, the overall thermal efficiency of the furnace should be considered to avoid unnecessary heat loss and ensure complete combustion of fuel. The sealing performance of the furnace door also affects the furnace's heat preservation. Utility Model Content

[0021] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Please see Figures 1 to 6 As shown, this application embodiment provides an energy-saving furnace door opening control device, applied to a furnace body 1 and a furnace door 2 installed at the front end of the furnace body 1. The upper end of the furnace door 2 is connected to an opening control mechanism. The opening control mechanism includes a set of hydraulic cylinders 3, a set of guide wheels 4, a set of steel wire connecting ropes 5, a set of mounting plates 6, a set of fixed slide rails 7, a sliding frame 8, and two sets of connecting rods 9. A set of hydraulic cylinders 3 is installed at the top front end of the furnace body 1. A set of guide wheels 4 are movably installed on the telescopic end of a set of hydraulic cylinders 3. A set of steel wire connecting ropes 5 are fitted on a set of guide wheels 4, and one end is fixed to the furnace body 1. A set of mounting plates 6 are installed on both sides of the front end of the furnace body 1. A set of fixed slide rails 7 are installed at the front end of a set of mounting plates 6. The sliding frame 8 is slidably installed on a set of fixed slide rails 7, and its upper end is connected to the other end of a set of steel wire connecting ropes 5. One end of each of the two sets of connecting rods 9 is hinged to the sliding frame 8, and the other end is hinged to the furnace door 2.

[0023] In this embodiment, a set of hydraulic cylinders 3 work synchronously, and servo valves are used to control the oil supply and discharge ports of the hydraulic cylinders 3 to achieve higher precision stroke control. This is the prior art. When the furnace door 2 is opened, the telescopic end of a set of hydraulic cylinders 3 extends, and the stroke is adjustable. This drives a set of guide wheels 4 to move upward, and through a set of steel wire connecting ropes 5, it pulls the sliding frame 8 upward. The sliding frame 8 drives the furnace door 2 to a suitable opening degree through two sets of connecting rods 9, which can prevent excessive cold air from being drawn in or heat from overflowing from the inside of the furnace body 1.

[0024] In some embodiments, a set of L-shaped mounting plates 10 are installed on both sides of the front end of the heating furnace body 1. A set of servo cylinders 11 are hinged to the rear end of the set of L-shaped mounting plates 10. A set of pressure plates 12 are hinged to the telescopic ends of the set of servo cylinders 11. When the telescopic ends of the set of hydraulic cylinders 3 retract, the furnace door 2 can be automatically closed. Then, the telescopic ends of the set of servo cylinders 11 extend, driving the set of pressure plates to press the sides of the furnace door 2 to increase sealing and heat preservation. Figure 6 As shown, the deflection angle of a set of pressure plates 12 is 0-90°.

[0025] In some embodiments, a set of pressure plates 12 are movably hinged to the front end of the corresponding L-shaped mounting plate 10 via a rotating shaft 13, which facilitates the deflection of the set of pressure plates 12. When the set of pressure plates 12 are opened, the set of fixed slide rails 7 will not cause interference.

[0026] In some embodiments, a set of mounting plates 6 are respectively provided with guide grooves 14. The upper outer side of the furnace door 2 is slidably mounted in the guide grooves 14 by a set of pulleys 15, which serve as guides. The bottom of the guide grooves 14 is provided with grooves 16. When the furnace door 2 is closed, when a set of pulleys 15 moves to the grooves 16, the furnace door 2 can be made to fit against the heating furnace body 1, which is convenient for the subsequent pressing of a set of pressure plates 12. When the furnace door 2 is opened, when a set of pulleys 15 disengages from the grooves 16, the two sets of connecting rods 9 deflect, such as Figure 5 As shown.

[0027] In some embodiments, the sliding frame 8 is slidably mounted on a set of fixed slide rails 7 via two sets of sliding blocks 17 on both sides, which facilitates the up and down movement of the sliding frame 8.

[0028] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
