Description

Technical Field

[0001] This utility model belongs to the field of coke reactive furnaces and relates to a coke reactive furnace that is easy to disassemble. Background Technology

[0002] The coke reactive furnace is a core piece of equipment for achieving a high-temperature reaction environment and ensuring stable production processes. The sealing performance and ease of disassembly and assembly of the furnace are directly related to production efficiency, equipment maintenance costs, and operational safety.

[0003] Currently, traditional coke reactive furnaces generally use flange connections to seal the furnace ports, that is, by fitting a flange plate and flange cover together, and then securing it with multiple bolts and nuts. However, this structure has many limitations in practical applications: Low disassembly and assembly efficiency: To ensure the sealing effect, the furnace port usually needs to be evenly distributed with 6 or more bolts. When disassembling manually, each bolt needs to be tightened one by one. The operation steps are cumbersome and time-consuming. Especially in scenarios where the furnace needs to be opened frequently for material replacement, internal maintenance or reaction parameter adjustment, it seriously restricts the continuity of production. Significant safety hazards: The internal temperature of the furnace is extremely high during operation. Even after the machine is shut down, the flange cover and surrounding components remain at high temperatures for a short period of time. When manually removing bolts or directly touching the flange cover, burns can easily occur, posing a threat to the personal safety of operators. Utility Model Content

[0004] The technical problem this utility model aims to solve is that manual disassembly requires tightening each bolt individually, which is cumbersome and time-consuming, especially in scenarios where the furnace needs to be frequently opened for material replacement, internal maintenance, or reaction parameter adjustment, severely restricting production continuity. Furthermore, the flange cover and surrounding components remain at high temperatures during disassembly, and manual bolt removal or direct contact with the flange cover can easily lead to burns, posing a threat to the personal safety of operators. The system includes a base, a furnace chamber mounted on its upper surface, a flange fixedly mounted at the furnace chamber's port, six nuts annularly mounted on the outer surface of the flange, a flange cover mounted on its upper surface, and six bolts annularly threaded through the outer surface of the flange cover. The six bolts are threaded through the flange and connected to the six nuts. A switching unit for adjustment is provided on the upper surface of the base. The outer surface of the connecting plate in the switching unit is equipped with a twisting unit for quickly removing the bolts, and a clamping unit for gripping and opening the flange cover. The torsion unit includes gear two, and there are six gear two. A connecting rod one is fixedly installed on the outer surface of the connecting plate. A housing is fixedly installed on one end surface of the connecting rod one. The six gear two are distributed in a ring in the inner cavity of the housing and are all rotatably connected. Torque sleeves for torsioning the bolt are welded and installed on the lower surface of each of the six gear two. The clamping unit includes a first clamp and a second clamp. A second connecting rod is fixedly installed on the outer surface of the connecting plate. A sliding shell is fixedly installed on one end surface of the second connecting rod. An electric threaded rod is fixedly installed on one side surface of the sliding shell. The working end of the electric threaded rod is located inside the sliding shell and is threadedly connected to the first clamp and the second clamp respectively.

[0005] A servo motor is fixedly installed on the upper surface of the outer shell of this utility model. The working end of the servo motor is fixedly installed with a gear one in the inner cavity of the outer shell. The gear one is meshed with six gears two.

[0006] The flange cover of this utility model has two locating pins welded and installed on its lower surface, and the two locating pins are engaged with the grooves opened on the upper surface of the flange.

[0007] The first clamp of this utility model is connected to the working end of the electric threaded rod in the forward thread, and the second clamp is connected to the working end of the electric threaded rod in the reverse thread.

[0008] The outer surfaces of both the first and second grippers of this invention are welded with positioning pins, and the outer surface of the flange cover has two positioning pin grooves.

[0009] The switching unit of this utility model includes a rotator, which is fixedly installed on the upper surface of the base. An electric push rod is fixedly installed at the working end of the rotator, and a connecting plate is fixedly installed at the working end of the electric push rod.

[0010] A stabilizing frame is fixedly installed on the upper surface of the base of this utility model, wherein the stabilizing frame is sleeved on the outer surface of the electric push rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By installing the bolts in the six torque sleeves of the torsion unit, starting the servo motor drives gear one to rotate, which in turn drives the six meshing gear twos to rotate simultaneously. This causes the six torque sleeves to rotate and disassemble the six bolts from the nuts. This achieves rapid disassembly of the six bolts, improving work efficiency. By aligning the positioning pin two of the clamping unit with the positioning pin groove, the electric threaded rod is activated to drive the clamping hands one and two to slide relative to each other on the sliding shell, thereby allowing the clamping hands one and two to clamp and release the flange cover. This avoids the flange cover, which is in a high-temperature state, from causing injury to people during manual disassembly, thus achieving a protective effect. Attached Figure Description

[0014] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.

[0015] like Figures 1 to 7As shown, a coke reactive furnace that is easy to disassemble includes a base 1, a furnace 2 installed on the upper surface of the base 1, a flange 4 fixedly installed at the port of the furnace 2, six nuts 5 annularly installed on the outer surface of the flange 4, a flange cover 6 installed on the upper surface of the flange 4, six bolts 7 annularly installed through the outer surface of the flange cover 6, the six bolts 7 threadedly connected to the flange 4 and the six nuts 5, a switching unit 3 for switching and adjusting is provided on the upper surface of the base 1, a torsion unit 8 for quickly disassembling the bolts 7 is provided on the outer surface of the connecting plate 34 in the switching unit 3, and a clamping unit 9 for clamping and opening the flange cover 6 is provided on the outer surface of the connecting plate 34 in the switching unit 3. Connecting rod 1 81 and connecting rod 2 91 are mounted opposite each other on connecting plate 34, and connecting plate 34 ensures the stability of the connection between connecting rod 1 81 and connecting rod 2 91.

[0016] The torsion unit 8 includes gear 2 85, and there are six gear 2 85. A connecting rod 1 81 is fixedly installed on the outer surface of the connecting plate 34. A housing 82 is fixedly installed on one end surface of the connecting rod 1 81. The six gear 2 85 are distributed in a ring in the inner cavity of the housing 82 and are all rotatably connected. Torque sleeves 86 for torsioning the bolt 7 are welded and installed on the lower surface of each of the six gear 2 85. Six gears 85 are arranged in a ring in the inner cavity of the outer casing 82 and are rotatably connected. Torque sleeves 86 are installed on the lower surface of each of the six gears 85. The torque grooves of the torque sleeves 86 match the bolts 7 and can magnetically hold the bolts 7 in place.

[0017] The clamping unit 9 includes a first clamp 94 and a second clamp 95. A second connecting rod 91 is fixedly installed on the outer surface of the connecting plate 34. A sliding shell 92 is fixedly installed on one end surface of the second connecting rod 91. An electric threaded rod 93 is fixedly installed on one side surface of the sliding shell 92. The working end of the electric threaded rod 93 is located inside the sliding shell 92 and is threadedly connected to the first clamp 94 and the second clamp 95 respectively.

[0018] Clamp 1 94 and clamp 2 95 are driven by electric threaded rod 93 to slide in sliding shell 92, and the clamping surface formed by clamp 1 94 and clamp 2 95 fits against flange cover 6.

[0019] like Figure 4 , Figure 5 and Figure 6 As shown, a servo motor 83 is fixedly installed on the upper surface of the housing 82. The working end of the servo motor 83 is fixedly installed with a gear 84 in the inner cavity of the housing 82. The gear 84 meshes with six gears 85.

[0020] Servo motor 83 drives gear 1 84 to rotate, which in turn drives six gears 2 85 to rotate. The gear ratio between gear 1 84 and the six gears 2 85 is 6:1.

[0021] like Figure 3 As shown, two locating pins 87 are welded and installed on the lower surface of the flange cover 6, and the two locating pins 87 are engaged with the grooves opened on the upper surface of the flange 4.

[0022] Two locating pins 87 engage in the grooves on the upper surface of the flange 4, ensuring that the flange cover 6 does not wobble when the torque sleeve 86 is disassembled and installed on the bolt 7, making the installation more stable.

[0023] like Figure 4 and Figure 7 As shown, clamp 1 94 is connected to the working end of electric threaded rod 93 by a forward thread, and clamp 2 95 is connected to the working end of electric threaded rod 93 by a reverse thread.

[0024] The electric threaded rod 93 can drive the first clamp 94 and the second clamp 95 to slide relative to each other in the sliding shell 92.

[0025] like Figure 3 , Figure 4 and Figure 7 As shown, locating pins 96 are welded and installed on the outer surfaces of clamp 1 94 and clamp 2 95, and two locating pin grooves 97 are opened on the outer surface of flange cover 6.

[0026] The locating pin 2 96 engages in the locating pin groove 97, making the clamping of the flange cover 6 more stable.

[0027] like Figure 1 As shown, the switching unit 3 includes a rotator 31, which is fixedly installed on the upper surface of the base 1. An electric push rod 32 is fixedly installed at the working end of the rotator 31, and a connecting plate 34 is fixedly installed at the working end of the electric push rod 32.

[0028] The rotator 31 consists of a motor, a differential, and a chassis. It can drive the electric push rod 32 to rotate. The electric push rod 32 can drive the torsion unit 8 and the clamping unit 9 to rise and fall, thereby ensuring the normal operation of the torsion unit 8 and the clamping unit 9.

[0029] like Figure 1 As shown, a stabilizer 33 is fixedly installed on the upper surface of the base 1, wherein the stabilizer 33 is sleeved on the outer surface of the electric push rod 32.

[0030] The stabilizer 33 ensures the stable operation of the electric push rod 32.

[0031] Working principle: To remove bolts 7, firstly, the rotation of the rotator 31 drives the electric push rod 32 to rotate, so that the outer shell 82 at one end of the connecting rod 81 is above the flange cover 6. The electric push rod 32 is started to lower the outer shell 82 until all six bolts 7 are installed in the grooves of the six torque sleeves 86. At this time, the servo motor 83 is started to drive the gear 84 to rotate, which in turn drives the six gears 85 to rotate, so that the six torque sleeves 86 rotate to disengage the six bolts 7 from the nuts 5. Then, the electric push rod 32 is started again to raise the outer shell 82. The six bolts 7 will be magnetically attracted in the six gears 85, thus detaching from the flange 4 and the flange cover 6. After detaching from flange 4, the electric push rod 32 is rotated by turning the rotator 31 so that the sliding shell 92 at one end of connecting rod 2 91 is above flange cover 6. The electric push rod 32 is then activated to lower the outer shell 82 until the positioning pin 2 96 is aligned with the positioning pin groove 97. At this time, the electric thread rod 93 is activated to drive the clamp 1 94 and clamp 2 95 to slide relative to each other on the sliding shell 92, thereby allowing the clamp 1 94 and clamp 2 95 to clamp and detach flange cover 6.

[0032] The above description is only a preferred embodiment of the present utility model.
