Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, specifically to a heater equipped with laser positioning. Background Technology

[0002] An loading arm (or arm for loading and unloading liquids) is a type of liquid handling equipment used in industries such as petroleum and chemical processing. It features a telescopic, tubular structure and is primarily used to replace traditional hoses for safe and efficient liquid transfer; it is also known as a fluid loading / unloading arm. Currently, high-viscosity crude oil transported by tanker trucks requires loading arms for unloading. To reduce oil viscosity, loading arms are often equipped with heat exchangers at their front end to heat the crude oil. However, during the heating process, the flow of oil and the heat exchange medium induces fluid vibrations. These vibrations can impact the heat exchanger body, causing the heat exchanger shell to collide with the tank opening, thereby threatening the structural integrity and sealing of the heat exchanger shell. Utility Model Content

[0003] This utility model addresses the problems mentioned above by specifically designing a heater equipped with laser positioning. It adds a support base to the oil tank opening, locks the assembly state of the heat exchanger body and the oil tank opening, reduces the impact of fluid impact and vibration on the heat exchanger body, and prevents collision between the heat exchanger body and the oil tank opening.

[0004] To achieve the above objectives, this utility model provides a heater equipped with laser positioning, including a submersible pump, an loading arm, and a heat exchanger body. The submersible pump and the loading arm are connected by the heat exchanger body. The heater also includes a frame, a three-way switching valve, and a support base. The loading arm is movably connected to the frame via a lifting transmission assembly. A three-way switching valve is provided at the connection between the heat exchanger body and the loading arm. One passage of the three-way switching valve is connected to the loading arm, and the other passage is connected to a circulation pipe. The circulation pipe leads into the opening of the oil tank. The support base is located at the opening of the oil tank and movably clamps the heat exchanger body. A laser positioning module is provided between the opening of the oil tank and the loading arm.

[0005] Furthermore, the oil tank opening is detachably equipped with a positioning plate, and the support base is installed at the oil tank opening via the positioning plate.

[0006] Furthermore, the support base includes an annular chassis, and drive cylinders and arc-shaped clamping blocks symmetrically arranged on both sides of the annular chassis. The annular chassis is fixedly connected to the positioning plate, and the cylinder body end of the drive cylinder is fixedly connected to the annular chassis, while the piston part is driven and connected to the arc-shaped clamping block.

[0007] Preferably, the arc-shaped clamping block is fixedly connected to an elastic pad.

[0008] Furthermore, the annular chassis is symmetrically provided with vertical through holes, and support legs are movably inserted into the vertical through holes.

[0009] Furthermore, the support leg includes a support column, and a limiting plate and a foot plate respectively fixed at both ends of the support column. The support column has multiple sets of transverse through holes in a linear array. A positioning pin is movably inserted into the transverse through hole, and the positioning pin is engaged with the annular chassis.

[0010] Furthermore, the bottom of the foot plate is provided with an arc-shaped groove that is adapted to the tank body of the oil tank.

[0011] Furthermore, the laser positioning module includes a laser detector and multiple signal transmitters. The signal transmitters are arranged in a circular array on the positioning disk, and the lasers of the signal transmitters converge at the center point of the oil tank opening. The laser detector is mounted on the loading arm via a mounting plate.

[0012] In summary, this utility model has the following advantages and beneficial technical effects: 1. This utility model adds a support base at the opening of the oil tank and uses a drive cylinder to drive an arc-shaped clamp to hold the heat exchanger body, locking the assembly state of the heat exchanger body and the oil tank opening, reducing the impact of fluid impact and vibration on the heat exchanger body, preventing the shell of the heat exchanger body from colliding with the oil tank opening, and thus preventing leakage or structural damage to the heat exchanger body.

[0013] 2. In this utility model, the submersible pump is used for efficient pumping of oil in the tank; the heat exchanger body is used to heat the oil and reduce its viscosity; the three-way switching valve can switch the oil delivery state, closing passage one and opening passage two to achieve internal circulation of the oil in the tank. After raising the oil temperature in the tank to the required temperature, passage one is opened and passage two is closed to achieve oil unloading. The laser positioning module adopts the triangulation principle and uses photoelectric recognition technology to quickly and accurately capture the target, effectively controlling positioning errors and ensuring that the submersible pump and heat exchanger body accurately extend into the oil tank.

[0014] 3. In this utility model, the support legs connect the annular chassis to the outer wall of the oil tank, improving the stability of the annular chassis assembly. The arc-shaped groove at the bottom of the foot plate increases its adaptability to the tank body.

[0017] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail as follows: like Figures 1-2 as well as Figure 4 As shown, this embodiment discloses a heater equipped with laser positioning, including a submersible pump 1, an loading arm 2, and a heat exchanger body 3. The submersible pump 1 and the loading arm 2 are connected by the heat exchanger body 3. It also includes a frame 4, a three-way switching valve 5, and a support base 6. The loading arm 2 is movably connected to the frame 4 through a lifting transmission assembly. The lifting transmission assembly is preferably a gear and rack lifter (not shown in the figure). The gear and rack lifter includes a gear, a rack, a drive motor, and a lifting platform. The rack is laid on the frame 4, and the loading arm 2 is installed on the lifting platform. When the drive motor outputs power, the drive gear rolls along the rack, and the lifting platform and the loading arm 2 rise and fall synchronously with the gear. The gear and rack lifter is existing technology, and its structure and transmission principle will not be described in detail here. A three-way switching valve 5 is provided at the connection between the heat exchanger body 3 and the loading arm 2. Passage 1 of the three-way switching valve 5 is connected to the loading arm 2, and passage 2 is connected to the oil inlet of the circulation pipe 7. The oil outlet of the circulation pipe 7 extends into the oil tank opening 10. The support base 6 is set at the oil tank opening 10 and is movably clamped to the outer wall of the heat exchanger body 3. A laser positioning module 9 is provided between the oil tank opening 10 and the loading arm 2.

[0018] like Figures 2-6As shown, a positioning plate 8 is detachably installed on the oil tank opening 10. The bottom of the positioning plate 8 has a groove that matches the oil tank opening 10. The positioning plate 8 is engaged with the oil tank opening 10 through the groove. The support base 6 is welded and fixed to the positioning plate 8. The support base 6 includes an annular base 61, and drive cylinders 62 and arc-shaped clamping blocks 63 symmetrically arranged on both sides of the annular base 61. The annular base 61 is welded and fixed to the positioning plate 8. The cylinder body of the drive cylinder 62 is fixed to the annular base 61 by screws, and the piston part is driven and connected to the arc-shaped clamping block 63 through a floating joint. An elastic pad 64 is glued to the inner wall of the arc-shaped clamping block 63. The central angle of the arc-shaped clamping block 63 is preferably 120°, and the curvature of the arc-shaped clamping block 63 matches the curvature of the outer wall of the heat exchanger body 3.

[0019] like Figure 4 as well as Figure 7 As shown, the annular base 61 has symmetrically arranged vertical through holes, and support legs 65 are movably inserted into the vertical through holes. Each support leg 65 includes a support column 651, and limiting plates 652 and foot plates 653 welded to both ends of the support column 651. The support column 651 has multiple sets of transverse through holes arranged in a vertical linear array. Positioning pins 654 are movably inserted into the transverse through holes, and the positioning pins 654 pass through the transverse through holes and engage with the annular base 61. The bottom of the foot plate 653 has an arc-shaped groove adapted to the tank body.

[0020] like Figure 1 as well as Figure 4 As shown, the laser positioning module 9 includes a laser detector 92 and four sets of signal transmitters 91. The signal transmitters 91 are embedded in the positioning disk 8 in a circular array, and the lasers emitted by the four sets of signal transmitters 91 converge at a single point, namely the center point of the tank opening 10. The laser detector 92 is mounted on the loading arm 2 via a mounting plate 93. The laser positioning module 9 uses triangulation, where the laser detector 92 detects the location of the converged laser point of the signal transmitters 91 at multiple heights. By applying the principles of trigonometric geometry to the distance to the tank opening 10, the heat exchanger body 3 and the submersible pump 1 are ensured to smoothly extend into the tanker truck. Triangulation is existing technology and will not be elaborated upon here.

[0021] The working principle of the heater equipped with laser positioning according to this utility model is as follows: During oil unloading, workers open the tanker truck cover, assemble the positioning plate 8 at the tank opening 10, and lower the outriggers 65 onto the tank body. When the foot plate 653 supports the surface of the tank body, workers insert the positioning pin 654 into the transverse through hole of the support column 651, so that the positioning pin 654 locks the annular chassis 61, limiting the relative displacement between the outriggers 65 and the annular chassis 61. Using the laser positioning module 9, the submersible pump 1 and the heat exchanger body 3 are vertically fed into the tanker truck from the tank opening 10. Then, the drive cylinder 62 is started, and the piston in the drive cylinder 62 drives the arc-shaped clamping block 63 to advance synchronously. The arc-shaped clamping blocks 63 on both sides lock the heat exchanger body 3. The submersible pump 1 delivers the oil in the tank to the heat exchanger body 3 for heat exchange. The passage of the three-way switching valve 5 is adjusted to close passage one and open passage two, so that the oil heated by flowing through the heat exchanger body 3 flows back to the tank through the circulation pipe 7, forming an internal circulation. Once the oil in the tank reaches the required temperature, open passage one of the three-way switching valve 5 and close passage two, then transport the oil through the heat exchanger body 3 to the loading arm 2 to unload the oil.

[0022] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
