Detailed description of the invention
The invention provides a kind of autoclave heat exchanger tube anti-vibration support, as shown in figures 1 to 6, comprise the vertical gripper shoe 1 arranged and be connected to the top of described gripper shoe and the pressing plate 2(of bottom or claim vibrationproof pressing plate) and gripper shoe support 3, described gripper shoe is provided with some pores 1.1, described gripper shoe adopts nonmetallic materials to make, such as PEEK, PTFE, RPTFE or ePTFE etc.The hardness number of the material of described gripper shoe, lower than the hardness number of the material of heat exchanger tube to be supported, therefore can be avoided exchanging heat pipe during poling and cause damage.Described pressing plate and gripper shoe support all can be made up of metal material, and preferably identical with the material of heat exchanger cylindrical shell or approximate.Described gripper shoe and the connected mode between described pressing plate and gripper shoe support are adjustable connecting mode that is nonmetal and metal.Because gripper shoe is all not identical with shape etc. with the material of heat exchanger tube, resonant frequency differs greatly, therefore gripper shoe exchange heat pipe resonance has obvious effectiveness in vibration suppression, and it is obviously different with heat exchanger tube from gripper shoe with size with the shape of pressing plate for the gripper shoe support of supported plate, material therefor and gripper shoe are also obviously different, thus while the enough support strengths of guarantee, the resonance of exchange heat pipe and gripper shoe produces further damping effect, simultaneously due to gripper shoe and all with bolts between gripper shoe support and pressing plate, can between gripper shoe and gripper shoe support, between gripper shoe and pressing plate, between gripper shoe and respective nut, the nonmetal damping pad (not shown) be enclosed within respective bolt is set between pressing plate and support panel respectively, utilize nonmetal damping pad and heat exchanger tube, gripper shoe, obvious resonant frequency difference between gripper shoe support and pressing plate, the transmission of further elimination heat exchanger tube resonance, through the vibration reducing measure of these resonance, brace foundation can be made substantially completely not by the impact of heat exchanger tube resonance.
Described pore is used for wearing heat exchanger tube, diameter preferably 0.1-0.3mm larger than the external diameter of heat exchanger tube to be supported, the more preferably large 0.2mm of described pore.This gap or interstice coverage are starkly lower than the gap value 0.7mm that existing national standard is recommended, and also lower than the gap value 0.4-0.8mm that Unite States Standard is recommended, therefore can retrain better, support heat exchanger tube, avoid heat exchanger tube to vibrate.Thus, deflection plate or gripper shoe spacing need not be reduced in order to make up the deficiency of original antihunt action, also would not affect heat transfer efficiency and fluid resistance is fallen.
The top of described gripper shoe can arrange slotted hole 1.2, and the bottom of described pressing plate also can relative set slotted hole, and the top of described gripper shoe is fixedly connected with double nut 5 by bolt 4 at corresponding slotted hole place with the bottom of described pressing plate.Adopt slotted hole can adjust relative position interior among a small circle between the two easily, also convenient adjustment assemblage gap.Double nut is adopted to play locking function.
Described pressing plate can have two, and the horizontal range between the lower end of two described pressing plates is less than the horizontal range between upper end, and the angle α between two described pressing plates is preferably 60-180 °, more preferably 150 °.Adopt this pressing plate that structure is set, the stable of described gripper shoe position can be kept better.
The bottom of described gripper shoe can arrange circular hole 1.3, and the upper end of described gripper shoe support also can relative set circular hole, and the bottom of described gripper shoe is fixedly connected with double nut 7 by bolt 6 at corresponding circular hole place with the upper end of described gripper shoe support.Double nut is adopted to play locking function.
Described gripper shoe support can have two, the bottom of two described gripper shoe supports gripper shoe described in vertical clamp standoff in parallel to each other.During use, described gripper shoe Bracket setting is in the bottom of autoclave heat exchanger.
Described gripper shoe support is preferably provided with opening up vertical groove, and the bottom of described gripper shoe just embeds in described groove, and the described circular hole on described gripper shoe support runs through the sidewall on the two sides of described groove.
Fig. 2 shows the shape of the preferred described gripper shoe of the present invention: described gripper shoe is roughly a cylinder " cup " shape component, the wall of " cup " is provided with breach, described breach extends to the bottom surface of " cup " always, and the line of the dual-side of described breach and the intersection point of bottom surface forms a unique straight flange on bottom surface.Described pore is arranged on described bottom surface, and during use, described bottom surface is vertically placed, and the straight flange on described bottom surface is placed horizontally at bottom and embeds in the groove of described gripper shoe support.
