The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and cannot be construed to the utility model
Limitation.
As shown in Figures 1 to 10, the embodiments of the present invention provide a kind of flue gas cut-off equipment, including doorframe 1, door
Plate 2 and driving device, doorframe 1 are welded by common channel steel, and door-plate 2 is formed using common steel or stainless steel and fashioned iron.Institute
The middle part for stating doorframe 1, which is run through, has cavity to form hollow structure, and 1 level of doorframe is horizontal to be fixed in vertical flue, leads to
The anti-flange arrangement and two side flues crossed in equipment weld, and 2 slip of door-plate is fixed in the doorframe 1, the door
It is fixed with demarcation plate 3 in the middle part of frame 1, the cavity is divided into fitting groove 4 and by slot 5 by the demarcation plate 3, and flue gas is from passing through
Pass through in slot 5, the doorframe 1 is fixed with sealing plate 24 in the two sides of the fitting groove 4 to form seal chamber, and seal chamber is mainly
In view of work condition environment compare it is severe, if running part be not added with protect, components are easy to rust, dust stratification, or even lead
Cause driving member stuck.The driving device is fixed in the seal chamber, and the output end of the driving device and the door-plate 2 connect
It connects, to drive the door-plate 2 in fitting groove 4 and by horizontal sliding between slot 5.
Further, the driving device includes drive lead screw 6, end bearing seat 7, middle part bearing block 8, pull rod 9, pull rod
Seal receptacle 10, hold-down support 11 and guide rail 12.
The end bearing seat 7 is fixed in the outside wall surface of the close fitting groove 4 of the doorframe 1, the middle part axis
Hold the end face close to 4 side of fitting groove that seat 8 is fixed on the demarcation plate 3, the end bearing seat 7 and the middle part axis
The axial line for holding seat 8 is overlapped with the axis of the doorframe 1, and the both ends of the drive lead screw 6 are nested in the end bearing respectively
In seat 7 and the middle part bearing block 8, speed reducer mounting flange 13 is fixed on the doorframe 1, speed reducer passes through on doorframe 1
Speed reducer mounting flange 13 is fixed, and speed reducer transmits torque to drive lead screw 6 when work, since the effect of two bearing blocks passes
Dynamic screw rod 6 only does rotary motion, does not do axial linear movement.When flue gas cut-off equipment realizes opening and closing, anti-work suffered by transmission shaft
Firmly mainly axial component, so all having selected thrust bearing 23 inside end bearing seat 7 and middle part bearing block 8.
Transmission pulling plate 14, the pull rod 9, the tie-rod sealing seat 10 and the fixation are bolted on the drive lead screw 6
There are two support 11 is all provided with, the two sides of the transmission pulling plate 14 are symmetrically set in, the hold-down support 11 is fixed on the door-plate 2
Side far from the end bearing seat 7, the tail end of the pull rod 9 are connect with the hold-down support 11, the tie-rod sealing seat
10 are fixed on the side away from the hold-down support 11 of the demarcation plate 3, and it is close that the middle part of the pull rod 9 penetrates through the pull rod
Seat 10 is sealed, to prevent flue gas along pull rod 9 to 6 place cavity internal leakage of drive lead screw, what is be arranged on pull rod 9 has tie-rod sealing seat
10, smoke spillage is prevented by way of packing seal, the head end of the pull rod 9 is fixedly connected with the transmission pulling plate 14, institute
It states there are two guide rail 12 sets, the both ends of the guide rail 12 are fixed with the doorframe 1 and the demarcation plate 3 respectively, the transmission drawing
The two sides of plate 14 are slidably matched with the guide rail 12 formation.Transmission pulling plate 14 is located in guide rail 12 through screw thread pair and drive lead screw
Rotary motion, is converted to the linear motion of transmission pulling plate 14 by 6 connections.Transmission pulling plate 14 is connected by pull rod 9 with door-plate 2,
The opening and closing function for overcoming force of rolling friction suffered by door-plate 2 that door-plate 2 can be driven to move in a straight line realization device when work.This dress
Set pull rod 9 and drive lead screw 6 in the same plane, it is ensured that 6 screw thread pair uniform force of drive lead screw, will not generate moment of flexure makes silk
Bar deformation.
Further, the inner wall of the doorframe 1 is provided with back-up roller wheel 15 in the bottom interval of the door-plate 2.Back-up roller
Wheel 15 is in the downside of door-plate 2, can guarantee that door-plate 2 is close to back-up roller wheel 15 always in this way, door-plate 2 opens or closes luck
It is dynamic steady.Driving device only needs to overcome the force of rolling friction of back-up roller wheel 15 when unlatching, without overcoming 2 gravity of door-plate, motor
Power can be much smaller, to reach energy-efficient purpose.
It is described by being provided with intermediate supports in slot 5 to prevent door-plate 2 from deforming middle position when 2 size of door-plate is larger
One end of wheel group 16, the intermediate supports wheel group 16 is fixedly connected with the doorframe 1, the other end and the fixed company of the demarcation plate 3
It connects.
The side for having back-up roller wheel 15 is leeward side, and the side of no back-up roller wheel 15 is inlet side, the design of 2 surrounding of door-plate
There is sealing device, use p-type sealing strip and seal trim strip two seals simultaneously on three directions, remaining direction design is
Seal groove 20.P-type sealing strip is a kind of silicone sealing strip resistant to high temperature, completely can with resistance to flue-gas temperature, while this material compared with
Soft to be tightly attached on door-plate 2, sealing effect is preferable.Seal trim strip is by corrosion resistant stainless steel material bending and molding, slightly
Some elasticity are installed but not compressible too tight close to door-plate 2, primarily serve the dust-proof effect without regard to abrasion door-plate 2.
As shown in fig. 6, the demarcation plate 3 is provided with the first p-type sealing strip 17 with 2, the door-plate, 2 leeward side of door-plate is close
Envelope is sealed using the first p-type sealing strip 17, is not washed away directly by flue dust since leeward side has door-plate 2 to keep off, so do not set herein
Set stainless steel seal trim strip.
As shown in fig. 7, be provided between the door-plate 2 and the inlet side of the sealing plate 24 first seal trim strip 18 and
Second p-type sealing strip 19.Being directly exposed in flue gas is the first seal trim strip 18, primarily serves dustproof effect, the first sealing
Play the role of sealing fume there are also the second p-type sealing strip 19 together in 18 rear of press strip.
As shown in figure 8, described one end by slot 5, which corresponds at the door-plate 2, is provided with seal groove 20.Door-plate 2 is closed
When can be inserted lower section seal groove 20, flue gas to leak from there need to by 90 ° twice steering, structure similar to one simply
Labyrinth-type excluder, so inleakage is smaller.
As shown in Figure 10, the second seal trim strip 21 is equipped between the doorframe 1 and the sealing plate 24 and third p-type is close
Strip of paper used for sealing 22, as can be seen from the figure the lower section of door-plate 2 is the back-up roller wheel 15 for supporting door-plate 2 to move, and the top of door-plate 2 is to be close to
The two seals of door-plate 2.Being directly exposed in flue gas is the second seal trim strip 21, primarily serves dustproof effect, the second sealing
21 rear of press strip is one of third p-type sealing strip 22, plays the role of sealing fume.
The structure, features, and effects of the present invention is described in detail based on the embodiments shown in the drawings, with
Upper described is only the preferred embodiment of the utility model, but the present invention does not limit the scope of implementation as shown in the drawings, it is all according to
Change or equivalent example modified to equivalent change made by conception according to the utility model, still without departing from specification and figure
When showing covered spirit, it should be within the protection scope of the present utility model.
