Description
Technical field
The invention belongs to heat exchange equipment technical field.
Background technology
Pipe heat exchanger, it is most typical dividing wall type heat exchanger, and its application industrially has long history, and the most still occupies leading position in all heat exchangers.Pipe heat exchanger is mainly made up of housing, tube bank, tube sheet and envelope first class sections, and how rounded housing is, and internal equipped with parallel tube bank, tube bank two ends are fixed on end plate.Being rotatably connected to spiral band (also known as twist iron, flow-disturbing band, twisted flat bar etc.) in tube bank, spiral band is mainly used in improving heat exchanger effectiveness.When fluid enters in heat exchanger tube, spiral band enters turbulent condition so that fluid, breaks tube wall retention layer, increase the contact area (i.e. improve heat exchange efficiency) of fluid and pipe wall of heat exchange pipe, and tube wall dirt can be washed away by the fluid of disorder.
The process equipment of existing spiral band includes roller machine, bead cutter, fixing roller, apparatus for baking, circumgyration stretch device, automatic gas cutting machine, air cooling equipment etc., stalloy material is delivered to bead cutter from roller machine, thin steel is cut into the sheet material meeting Rack by bead cutter, sheet material enters apparatus for baking after fixing roller, sheet material is carried out heat treatment, through the sheet material of Overheating Treatment, through circumgyration stretch device, (i.e. sheet material one end is fixed again, the other end is rotated by circumgyration stretch device) form spiral band, (being i.e. cut into the spiral band of specific length) is cut off by air cooling equipment sizing cooling again through automatic gas cutting machine.
The shortcoming of this spiral band is: when 1, circumgyration stretch device is rotated, the pitch of sheet material is formed to be affected by factors such as circumgyration stretch device rotary speed, turn secondary, sheet material transporting velocities, some pitch (being functionally equivalent to flow-disturbing unit hereafter) of the spiral band ultimately formed are incomplete same, after such spiral band is arranged in tube bank, the flow-disturbing dynamics that in tube bank, diverse location fluid is subject to is different, causes heat exchange uneven；Or circumgyration stretch device arranges unreasonable, when turning time too much, sheet material can be made to be twisted into two parts；When 2, cutting off spiral band, automatic gas cutting machine is along the cross-sectional direction feeding cutting knife of spiral band, and cutting knife is easily destroyed the spiral-shaped of spiral band, causes waste product.
Summary of the invention
The invention is intended to provide that a kind of flow-disturbing element length is identical, the flow-disturbing band process equipment of flow-disturbing cell configuration will not be destroyed when cutting off.
This programme flow-disturbing band process equipment, it is divided into trimming mechanism, heat treatment mechanism, twist mechanism and air cooling mechanism according to sheet material conveying direction, prewire cutting mechanism it is provided with between described heat treatment mechanism and twist mechanism, this prewire cutting mechanism includes two groups of all vertical with sheet material conveying direction cutting knife and controls the actuating unit that cutting knife moves up and down, and includes two cutting knife being not in contact with each other but be located along the same line with in group cutting knife；Described twist mechanism includes two grip blocks being parallel to each other, and is connected and controls the gear mechanism that grip block rotates with grip block, and the opposite face of said two grip block is provided with the groove parallel with sheet material conveying direction.
Beneficial effect: actuating unit controls cutting knife and moves down crush-cutting sheet material formation prewire, owing to two cutting knife in same group are not in contact with each other, so not connecting with group two prewires of two cutting knife crush-cuttings, additionally, cutting knife is all vertical with sheet material conveying direction, and two prewires gone out with interior two the cutting knife crush-cuttings of group are located along the same line and vertical with sheet material conveying direction；And forming flow-disturbing unit between two groups of cutting knife crush-cuttings out prewire of 4, the length of all flow-disturbing unit is identical；The groove of grip block blocks the edge of the flow-disturbing unit of sheet material, and gear mechanism drives grip block to rotate so that flow-disturbing unit reverses.First, this programme uses prewire to carry out the length of specification flow-disturbing unit, and the flow-disturbing element length of finished product flow-disturbing band is identical, after flow-disturbing band is arranged on tube bank so that the flow-disturbing dynamics that in tube bank, the fluid of diverse location is subject to is identical, and heat exchange is more uniform；Secondly, this programme eliminates traditional circumgyration stretch device, avoid the situation that the sheet material occurring tradition circumgyration stretch mode to cause is twisted off, this programme uses grip block carry out flow-disturbing unit spacing and reverse, the torsion of single flow-disturbing unit does not affect remaining position of sheet material, i.e. can control windup-degree and the torsional direction of flow-disturbing unit by controlling the motion mode of gear mechanism；Again, owing to cutting knife crush-cutting sheet material defines cross section, the overall surface area of final sheet material increases so that the flow-disturbing band after molding is through air cooling mechanism, bigger with the contact area of cold wind, improves the cooling effect of flow-disturbing band；Finally, when final cut-out flow-disturbing band, manual or automatic cutting machine is used to cut at prewire, owing to the connecting portion of adjacent flow-disturbing unit is narrower, cutting workload is less, the efficiency of cutting is compared traditional mode and is also improved a lot, and will not destroy the shape of flow-disturbing unit in cutting process.
Further, described twist mechanism also includes two supports, be rotatably assorted on each support swivel becket, two grip blocks are respectively positioned between the swivel becket of two supports, the termination of each grip block is fixing with the swivel becket of its homonymy to be connected, grip block rotates under the drive of gear mechanism, rotates the bad rotation to grip block and carries out spacing, it is ensured that the slewing area of grip block is without departing from the slewing area of swivel becket.
Further, described gear mechanism includes driving gear and driven gear, and driven gear is half gear, half flank of tooth of driven gear engages with driving gear, the non-flank of tooth of driven gear and two fixing connections of grip block, driving gear drives half pinion rotation, half gear then to drive grip block to rotate.
Further, described is 2cm with the distance organized between interior two cutting knife, and this distance is more suitable, the connecting portion between adjacent flow-disturbing unit can be avoided to rupture, also allow for the final cutting of flow-disturbing band after flow-disturbing band molding before flow-disturbing band molding.
Further, heat treatment mechanism include being positioned at same vertical on upper heat conduction roller, lower heat conduction roller, form the heating gap passed through for sheet material between upper heat conduction roller and lower heat conduction roller so that sheet material is heated, it is simple to cutting knife cuts.
Further, described air cooling mechanism includes forced air cooled tube and air-cooler, and air-cooler delivery outlet is by being connected with forced air cooled tube communicating pipe, and the flow-disturbing band in forced air cooled tube can be cooled down by the cold wind that air-cooler is sent.
Further, described actuating unit is telescopic cylinder, and cost is relatively low, and telescopic cylinder drives cutting knife to move down crush-cutting sheet material.
