Description

Technical Field

[0001] This invention relates to the field of pipeline heating furnace technology, specifically to a skid-mounted pipeline heating furnace for crude oil transportation. Background Technology

[0002] Pipeline heaters are widely used in the petrochemical industry, playing an important role in heating and transporting crude oil, heavy oil, and other oil products. However, with current technology, descaling and maintaining the heating elements of pipeline heaters requires dismantling and moving them to a maintenance location with sufficient space because the existing heaters are in a fixed position. This results in the fixed position affecting the maintenance space and reducing the stability of operation during subsequent maintenance. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a skid-mounted pipeline heater for crude oil transportation, which solves the problem that the fixed position of a single heater affects the maintenance space during subsequent repairs and reduces the stability of operation after maintenance.

[0006] Preferably, a motor is fixedly connected to the outer wall of the support frame, and a transmission rod is fixedly provided at the output end of the motor. The outer wall of the transmission rod is rotatably connected to the inside of the support frame.

[0007] Preferably, a crank is fixedly connected to the outer wall of the transmission rod, a positioning plate is provided on the outer wall of the crank, a buffer groove is provided inside the positioning plate, and the outer wall of the crank is set on the inner wall of the buffer groove.

[0008] Preferably, the outer wall of the positioning plate is slidably connected to a guide rail, and the outer wall of the guide rail is fixedly connected to the inner wall of the support frame.

[0009] Preferably, a top rod is fixedly connected to the upper surface of the positioning plate, the outer wall of the top rod is slidably connected to the inside of the protective shell, a movable plate is fixedly connected to the top end of the top rod, the outer wall of the movable plate is slidably connected to the inner wall of the protective shell, and a slot is formed inside the movable plate.

[0010] Preferably, the outer wall of the limiting block is disposed on the inner wall of the slot.

[0011] Preferably, a fixing plate is fixedly connected to the lower surfaces of both sides of the movable frame, and a connecting plate is rotatably connected to the outer wall of the fixing plate.

[0012] Preferably, a transmission block is rotatably connected to the outer wall of the connecting plate, and a composite plate is fixedly connected to the upper surface of the transmission block.

[0013] Preferably, the lower surface of the composite plate is disposed on the upper surface of the protective shell, a guide plate is fixedly connected to the lower surface of the composite plate, a limiting groove is formed inside the protective shell, and the outer wall of the guide plate is slidably connected to the inner wall of the limiting groove.

[0014] Working principle: When the heating furnace is needed, the main body of the skid-mounted pipeline heating furnace is started to start heating by connecting the inlet and outlet liquid channels to the outside of the main body of the furnace. When the main body of the skid-mounted pipeline heating furnace needs to be inspected and repaired, the equipment is first shut down and the connections of each pipe are disconnected. Then the hydraulic cylinder is activated. The output end of the hydraulic cylinder can push the moving frame to slide upward on the inner wall of the protective shell. The moving frame can drive the fixed plate to move upward. Through the connecting plate, the plate on the upper surface of the transmission block is pushed to move to both sides, thereby opening the inside of the protective shell and facilitating the inspection and repair of the main body of the skid-mounted pipeline heating furnace.

[0015] Simultaneously, as the moving frame moves upward, it can synchronously drive the inclined plate upward. At this time, the second spring rebounds, pushing the slider to slide outward inside the protective shell. This causes the inclined plate to fit against the inner wall of the protective shell and slide outward, sliding the skid-mounted pipeline heating furnace body out of the inner wall of the protective shell. At this time, the limit block slides to the inner wall of the slot, and the motor is turned on. The output end of the motor can drive the transmission rod to rotate, which in turn drives the crank to rotate synchronously. Through the buffer groove, the positioning plate moves back and forth up and down on the outer wall of the guide rail. At this time, the top rod drives the movable plate to slide up and down synchronously on the inner wall of the protective shell. Through the limit block in the slot, the moving frame moves up and down as a whole. This causes the first spring to drive the vibrating plate to vibrate up and down on the inner wall of the fixed frame. Through the support, the skid-mounted pipeline heating furnace body vibrates. This achieves the effect of vibrating the skid-mounted pipeline heating furnace body during maintenance, so that the dirt attached to the inner wall of the skid-mounted pipeline heating furnace body and other component surfaces are subjected to impact force and shearing, achieving the effect of removing dirt and checking internal blockages.

[0016] When maintenance is completed, the hydraulic cylinder is activated to move the moving frame downwards. At this time, the pressure between the inclined plate and the inner wall of the protective shell causes the slider to gradually slide inwards inside the moving frame, thereby causing the limit block to disengage from the inner wall of the slot and causing the clamping block to move inwards until the skid-mounted pipeline heating furnace body moves into the interior of the protective shell. Then, the clamping block contacts the outer wall of the skid-mounted pipeline heating furnace body, thereby achieving fixed clamping of the skid-mounted pipeline heating furnace body and ensuring the stability of the skid-mounted pipeline heating furnace body during operation. At the same time, the fixing plate moves downwards, and the connecting plate can drive the closing plate to close the upper surface of the protective shell, ensuring the protective effect of the skid-mounted pipeline heating furnace body during use.

[0017] This invention provides a skid-mounted pipeline heating furnace for crude oil transportation. It has the following beneficial effects:

[0018] 1. This invention drives the moving frame downward by opening the hydraulic cylinder. The inclined plate presses against the inner wall of the protective shell, causing the slider to gradually slide inward within the moving frame. The clamping block moves in the center and contacts the outer wall of the heating furnace, thus fixing and clamping it to ensure stability during operation. At the same time, when the moving frame moves upward, it can move the heating furnace to the upper surface of the protective shell, causing the clamping block to detach from the outer wall of the heating furnace, thereby expanding the maintenance space.

[0019] 2. This invention activates the hydraulic cylinder, pushing the movable frame to move the inclined plate upwards. The second spring rebounds, causing the slider to slide outwards, thus sliding the skid-mounted pipe heating furnace body out. After the limit block enters the slot, the motor is turned on. The motor drives the transmission rod and crank to rotate, causing the positioning plate to slide up and down on the guide rail. This, via the top rod and movable plate, drives the movable frame, which in turn causes the vibrating plate to vibrate through the first spring, thereby causing the heating furnace body to vibrate, removing dirt and checking for internal blockages.

[0020] 3. This invention activates the hydraulic cylinder, whose output end pushes the moving frame to slide upward, causing the fixed plate to rise. The connecting plate pushes the connecting plate on the transmission block to open to both sides, moving the skid-mounted pipe heating furnace above the protective shell for easy maintenance of the skid-mounted pipe heating furnace body. At the same time, the hydraulic cylinder activates the fixed plate to slide downward, and the connecting plate drives the connecting plate to close the upper surface of the protective shell, ensuring the protective performance of the equipment during use.
