Detailed Description

In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings.

It should be noted that in the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those described herein. Accordingly, the scope of the present invention is not limited by the specific embodiments disclosed below.

As shown in fig. 1, the present application provides an apparatus for wrapping an electric tracing band outside a reactor, including a roller press 100, a rotating shaft 200, and a support frame 300. Wherein the roller 100 has a cylindrical shape, and the roller 100 is rotatable around the axial direction thereof. Specifically, the rolling cylinder 100 is rotatably sleeved on the rotating shaft 200, and one end of the rotating shaft 200 is fixed on the supporting frame 300. It can be understood that the limit stopper 210 is disposed at the end of the rotating shaft 200 after penetrating out of the roller 100 to prevent the roller 100 from being removed from the rotating shaft 200. The rolling cylinder 100 is prevented from being provided with a first limit stop ring 410 and a second limit stop ring 420 at a spacer, and a position between the first limit stop ring 410 and the second limit stop ring 420 for the electric trace heating tape to smoothly pass through and stabilize the electric trace heating tape, so that an axial distance between the first limit stop ring 410 and the second limit stop ring 420 should be not less than a width of the electric trace heating tape, preferably close to the width of the electric trace heating tape, so as to be just embedded between the first limit stop ring 410 and the second limit stop ring 420.

When the equipment provided by the application is used for wrapping the electric tracing band outside the reactor, the following steps are carried out:

(1) cleaning the bottom of the reactor, and using tools such as a rust remover to treat and clean rust, dust and oil stains on the surface of equipment, so as to ensure that the contact part of the electric tracing band and the bottom of the reactor is clean and free of impurities;

(2) as shown in fig. 2, the end of the electric trace band 500 is wound from above the roller 100 to below the roller 100, and it is required that the electric trace band 500 passes through the annular gap between the first and second limit stop rings 410 and 420;

(3) pressing the rolling cylinder 100 to press the electric tracing band to the surface of the reactor and fix the end of the electric tracing band at the starting point of the reactor where the electric tracing band is wound;

(4) while the electric tracing band is continuously discharged from the wire coil, the rolling cylinder 100 is pushed in the direction of the arrow in fig. 2 to spirally travel around the outer circumferential surface of the reactor, and the rolling cylinder 100 draws the electric tracing band 500 out of the spiral winding to the surface of the reactor during the travel of the rolling cylinder 100.

It should be particularly noted that after the first spiral winding of the electric tracing band is completed, in the process of continuously pushing the rolling cylinder 100 to advance, the position of the rolling cylinder 100 is controlled to make the outer end face of the second limit stop ring 420 on the rolling cylinder 100 abut against the side face of the wound first electric tracing band, so that a stable distance (which is equal to the axial width of the second limit stop ring 420) can be maintained between the second electric tracing band and the first electric tracing band, and the electric tracing band is wound regularly to ensure uniform heating (as shown in fig. 5).

In order to allow the surface of the roller tube 100 to be adhered to the surface of the electric trace band during the winding process of the electric trace band to apply force to the electric trace band to be pressed to the surface of the reactor, it can be understood that the radial thickness of the first and second stopper rings 410 and 420 should be not more than the thickness of the electric trace band, preferably, approximately the thickness of the electric trace band.

Referring to fig. 1 again, in another embodiment, the apparatus for wrapping an electric tracing band provided by the present application further includes a plurality of adjustment stop rings 430, the adjustment stop rings 430 and a second limit stop ring 420 are sleeved on the roller 100 side by side, and the adjustment stop rings 430 are detachably connected to the second limit stop ring 420. The arrangement is such that the winding distance of the electric tracing band can be conveniently changed, and the sum of the widths of the adjusting baffle ring 430 and the second limit baffle ring 420 determines the spiral winding distance of the electric tracing band.

If it is necessary to increase the winding distance of the electric tracing band, one or more adjustment rings 430 are added to the outside of the second limit stop 420. When the electric tracing band is wound, the end surface of the added adjusting baffle ring 430 abuts against the side surface of the corresponding wound electric tracing band of the previous circle, so that the change of the winding distance is realized.

In order to fix the adjusting stop ring 430 and the second limit stop ring 420 and prevent them from falling off the roller tube 100 or moving randomly, the end surfaces of the adjusting stop ring 430 and the second limit stop ring 420 can be selected to be attracted by magnetic force. In this embodiment, when the adjustment stopper 430 is added, the adjustment stopper 430 is fitted from the end of the roller 100 to the roller 100, and the adjustment stopper 430 is moved to be sucked to the end surface of the second limit stopper 420. When the adjustment baffle ring 430 needs to be added, the next adjustment baffle ring 430 is attracted to the end face of the previous adjustment baffle ring 430.

In addition, the adjusting stop ring 430 and the second limit stop ring 420 may be connected by a bolt 431. Specifically, the second limit stop ring 420 and the adjusting stop ring 430 are respectively provided with a threaded hole 432, the threaded hole 432 on the adjusting stop ring 430 penetrates through two end faces of the adjusting stop ring 430, and the second limit stop ring 420 and the adjusting stop ring 430 are connected through a bolt 331 which simultaneously penetrates through the threaded holes 432 on the second limit stop ring 420 and the adjusting stop ring 430. When the adjusting stop ring 430 is added, the adjusting stop ring 430 is sleeved on the roller tube 100, so that the threaded hole 432 on the adjusting stop ring 430 is aligned with the threaded hole 432 on the second limiting stop ring 420, and then the two can be fixed by screwing the bolt 431. In order to prevent the head of the bolt 431 from protruding out of the end surface of the adjustment stopper 430 and the end surface of the adjustment stopper 430 from smoothly abutting against the side surface of the electric trace ribbon, a counter bore 433 may be provided at the end of the bore of the bolt 431 for the head of the bolt 431 to sink into. When the adjustment ring 430 is removed, the adjustment ring 430 can be removed by loosening the corresponding bolt 431.

Generally, two threaded holes 432 are formed in the second limit stop ring 420, and a counter bore 433 for sinking the head of the bolt 431 is not required. While the adjustment collar 430 is generally provided with four threaded holes 432, as shown in fig. 4, two of the threaded holes 432 are provided with counterbores 433 at the ends thereof, and the other two threaded holes 432 are not provided with counterbores 433. Two threaded holes 432 provided with counterbores 433 are used for connecting the adjusting stop ring 430 with the second limiting stop ring 420 or the previous adjusting stop ring 430, and two threaded holes 432 not provided with counterbores 433 are used for connecting the adjusting stop ring 430 with the next adjusting stop ring 430.

The first limit stop ring 410 mainly functions to limit the electric tracing band, and its axial width does not generally need to be changed.

As shown in fig. 1, in one embodiment, the support frame 300 is an L-shaped structure formed by connecting a cross bar 310 and a longitudinal bar 320, the longitudinal bar 320 is connected perpendicular to the rotation shaft 200, and the cross bar 310 is parallel to the axis of the roller 100 and is close to the surface of the first limit stop ring 410 or the second limit stop ring 420. With such an arrangement, the interference of the support frame 300 on the rolling cylinder 100 and the electric tracing band can be avoided as much as possible.

Further, a handle 330 may be disposed on the cross bar 310, and the handle 330 is vertically connected to the cross bar 310 to facilitate pushing the roller 100 to travel. Further, a non-slip structure 331 may be disposed on the handle 330, and the non-slip structure 331 includes, but is not limited to, a non-slip protrusion, a non-slip mat, and may be a sweat pad.

Further, in order to distribute the force applied to the connection point of the handle 330 and the cross bar 310, the handle 330 is further connected to the cross bar 310 by means of the diagonal brace 332.

In order to guide the traveling path of the electric tracing band during the winding process, as shown in fig. 3, in another embodiment, guide rollers 340 are provided on the cross bar 310, the guide rollers 340 are rotatably installed on the cross bar 310, and the guide rollers 340 are disposed parallel to the axis of the roller press 100 and adjacent to the surface of the first stopper ring 410 or the second stopper ring 420.

When the electric tracing band passes between the cross bar 310 and the roller cylinders 100, the electric tracing band is in rolling contact with the guide rollers 340, thereby preventing the electric tracing band from being scratched. In practice, if the electric tracing band is not suitable for excessive bending due to its high hardness, the distance between the cross bar 310 and the roller 100 may be increased appropriately.

As shown in fig. 3, the roller 100 may be configured as a hollow cylinder 110, two ends of the cylinder 110 are sealed by end caps 120, and the rotation shaft 200 is rotatably connected to the end caps 120. It will be appreciated that the near solid construction of roller 100 shown in fig. 1 may reduce the force of the builder pressing down on the roller to some extent.

In addition, in order to ensure the heating effect, a double-loop electric tracing band is usually adopted for laying, and two coils of electric tracing bands are respectively placed on a pay-off reel during construction and are respectively responsible for laying for one loop. When the wrapping equipment is applied to double-loop laying of the electric tracing bands, the number of the adjusting baffle rings 430 is determined according to the spiral winding distance of a single electric tracing band, for example, three adjusting baffle rings 430 are needed to be added to control the spiral winding distance of a first electric tracing band to be 20cm, after the three adjusting baffle rings 430 are installed on the rolling cylinder 100, the first electric tracing band is wound according to the steps, and the electric tracing band with the length of about 60m is generally needed for a reactor with the diameter of about 3 m.

After the first electric tracing band is wound, the two adjusting baffle rings 430 are taken down, the second electric tracing band is wound according to the method, and the final spiral winding distance of the electric tracing band outside the reactor is controlled to be 10 cm.

After the two electric tracing bands are wound, adhering and fixing the electric tracing bands on the surface of the reactor by using aluminum foil tapes at intervals of 20 cm; the tail end of the electric tracing band is sealed by a tail end box, and the head end of the electric tracing band is connected with a power line through a power supply box.
