Description

Technical Field

[0001] This invention relates to metallurgical furnaces, and more specifically, to a binding and regulating system for a furnace. Background Technology

[0002] Metallurgical furnaces are used to process ferrous and non-ferrous ores in the form of smelting and / or melting. These furnaces are typically circular or rectangular and include a furnace chamber, rising walls made of refractory bricks, and a furnace roof. In the case of rectangular furnaces, the furnace chamber and walls are typically clad externally with a metallic cladding, and a row of spaced-apart external frame members are used to secure and support the furnace walls. The frame members are interconnected and secured in place by a combination of rigid members and a flexible binding system. This binding system typically includes multiple tie rod assemblies extending longitudinally from one end of the furnace to the opposite end below the furnace chamber and above the furnace roof. In the transverse direction, the binding system typically includes multiple sets of independent binding actuators fixed to the frame members and extending between the frame members and the furnace sidewalls.

[0003] During operation, the furnace walls, frame, tie rod assemblies, and individual actuators are subjected to considerable thermal and mechanical forces due to the smelting or melting process within the furnace. The tie rod assemblies and individual actuators include tensioning devices to maintain pressure on the furnace chamber and furnace walls.

[0004] The introduction of US 6,814,012 mentions the known use of compression spring assemblies as tensioning devices. Various disadvantages of compression spring assemblies are listed and discussed. One disadvantage is that known spring assemblies require manual adjustment to ensure that the pressure on the furnace and sidewalls remains relatively constant during furnace operation. US 6,814,012 then teaches against the use of spring assemblies and discloses a tie rod assembly including a fluid-pressurized tensioning device. The applicant argues that under certain operating conditions, it has been demonstrated that fluid-pressurized tensioning devices may not reliably maintain the intended force; therefore, the aforementioned fluid-pressurized tensioning devices are unsuitable, at least in certain applications.

[0047] The first adjustable spring-loaded actuator 22 is in Figure 5 As best shown, these actuators are mounted between adjacent frame members, such as frame members 20.3 and 20.4. The actuators include a cylinder 54 having a first end 56 and a second end 58. A compression spring 60 is located within the cylinder, having a first end and a second end. The first end of the compression spring abuts directly or indirectly (via optional other components) against a first movable piston 62, which extends beyond the first end of the cylinder to abut against the furnace sidewall 16.2. The second end of the compression spring abuts directly or indirectly (via optional other components) against a second movable piston 64, which extends beyond the second end of the cylinder and abuts directly or indirectly against a first adjusting structure 68 (in the form of an internally threaded nut in this exemplary embodiment) on the externally threaded portion of a first rod 70, which is securely mounted to the frame 20, via a first interlocking device 66 of an axially movable member.

The actuator 24 includes a compression spring 80 (in this embodiment, in the form of an elongated compression spring) located within a cylinder 82 having a first end 84 and a second end 86. The actuator also includes a movable piston 88 defining an orifice 90, a lever 34 extending through the cylinder and the orifice 90, the cylinder being mountable at one end 84 to a fixed frame member 20.1, the compression spring 80 directly or indirectly abutting against the movable piston 88, which extends beyond the second end 86 of the cylinder and directly or indirectly abuts against a second adjusting structure 94 via a second interlocking device 92 of an axially movable component. In this embodiment, the second adjusting structure 94 is in the form of an internally threaded nut on the externally threaded end 98 of the lever 34. The second interlocking structure 92 includes a second collar structure 96 adjacent to the nut 94, which is axially adjustable on the lever 34 to adjust the pressure in the compression spring. The second interlocking structure 92 also includes a first sensing device 28 having an output end 30. When actuated, nut 94 engages with the threaded portion of the pull rod and is used to adjust the compression of the spring, thereby adjusting the tension applied to the pull rod 34 during use.

[0049] like Figure 1 and Figure 4 As shown, electrical signal output terminals 30 and 52 are connected to a first local station 104 via wires 100 and 102, respectively. The first local station 104 is appropriately located near the furnace 12. The first station 104 can be in the form of a junction box. Figure 4 As best shown, the first station 104 communicates with the second station via signals or data, and the second station may be located in a control room 106. In this example embodiment, the control room 106 houses a remote computerized controller 32, which may include a computer system or server 108, a database 110 connected to the server, and a monitor 112 for use by an operator 114.

[0050] Output signals or data from the first sensor 28 and the second sensor 36 on the multiple lever assemblies 16 and actuators 22 are processed under the control of a computer program, and the resulting data is displayed on a monitor, the computer program running on a computerized controller 32. This data enables operator 114 to instruct a second operator (not shown) to maintain the furnace and to manually operate the nuts 68, 48 of designated actuators 22, 24 using suitable tools (also not shown), thereby adjusting the compression of the associated compression springs and the force applied by the actuators 22, 24.

[0051] The second embodiment of the second type of actuator 24 is in Figures 7 to 9 As shown in the figure, and generally referred to as 120. A second embodiment 120 of the second actuator includes an actuator 24 (as referenced above). Figure 6 The aforementioned) and the remotely controllable hydraulic operating device 122 (in Figure 8 and Figure 9 (best shown in the diagram) and a remotely controllable nut operating device 124. The remotely controllable hydraulic operating device 122 is capable of releasing the nut 94 from the collar structure 96. It should be understood that the second embodiment 121 of the first type of actuator 22 (as shown in the diagram) Figure 11 (As shown) may include similar remotely controlled nut release devices and similar remotely controlled nut manipulation devices, which operate in a manner similar to that described below with respect to the second embodiment 120 of the second type of actuator.

[0052] Reference Figure 8 and Figure 9 The nut release device 122 includes a cylinder and a piston assembly 126. The piston assembly 126 includes a hydraulic cylinder 128 threadedly connected to a threaded end 98 of a pull rod 34. A mating cylindrical piston portion 130 has an end 132 defining an opening 134 large enough to allow a nut 94 to pass through. The piston portion 130 is coaxially mounted on the pull rod, with its end 132 abutting against a collar structure 96. The assembly 126 defines an annular chamber 136 for pressurizing fluid, preferably hydraulic fluid. A remotely controlled pump (not shown) controls the entry and exit of hydraulic fluid from the chamber 136 via a conduit 138.

[0053] In the first configuration or normal operating configuration of the tie rod assembly (e.g.) Figure 8 As shown, nut 94 abuts against collar structure 96 as described above. By allowing hydraulic fluid into chamber 136, the nut can be released from collar structure 96, which causes chamber 136 to expand, and the cylindrical piston 130, end 132 of cylindrical piston 130, collar structure 96, and the aforementioned second interlayer device (including first sensing device 28) between end 132 and movable piston 88 move in direction A away from nut 94, thereby releasing the nut from collar structure 96 and making nut 94 operable.

[0054] The nut operating device 124 includes a rotatable member 140 that defines a suitably shaped socket for receiving a nut 94. The member 140 can be selectively rotated clockwise or counterclockwise by a motor 142 via a shaft 144 and a gear train 146 housed in a gearbox 148.

[0055] As in Figure 10 and Figure 11The best illustration obtained is that the pumps and motors of the nut release device 122 and nut operating device 124 of the second embodiment 120 of the second type of actuator, and the pumps and motors of the nut release device and nut operating device of the second embodiment 121 of the first type of actuator, can all be controlled by control signal 150, which comes from remote computerized controller 32 in control room 106.

[0056] Therefore, in use, if the computerized controller 32 determines, based on signals 152 received from sensors 28, 36, that the compression springs 60, 80 of any of the plurality of actuators 120, 121 need to be adjusted, it generates the necessary control signal 152. First, the pump is driven with control signal 154 to release the relevant nuts 48, 68 (as described above), and then the motor is driven with control signal 156 to manipulate the released nuts in the desired direction. It should be understood that, utilizing... Figure 11 The second embodiment 120 of the first type of actuator and the second embodiment 121 of the second type of actuator shown, as well as bidirectional signal communication 152, 150, 154, 156, allow the second operator to operate the associated and specified nuts 48, 68 without manual operation.

[0057] Figures 12(a) and 12(b) show the first alternative and / or additional load sensing mechanism 200, and Figures 13(a) and 13(b) show the second alternative or additional load sensing mechanism 300.

[0058] Referring to the second type of actuator 24, the first mechanism 200 includes a measuring device for measuring the change in distance d1 between point 202 on cylinder 82 and fixed point 204 on pull rod 34, wherein point 202 abuts against frame member 20.1. The change in distance is proportional to the length of the compression spring, and therefore proportional to the compression of the spring. The change in force applied by spring 80 is calculated using the well-known formula F = Kd1.

[0059] Referring to Figures 13(a) and 13(b), the change in distance can be measured by proximity switches 302, 304 and 306 spaced apart on the lever 34.
