Description

Technical Field

[0002] Electric heaters are an internationally popular type of electric heating device used to heat, insulate, and heat flowing liquid and gaseous media. When the heating medium passes under pressure through the heater's heating chamber, the principles of fluid thermodynamics evenly dissipate the enormous heat generated by the heating element. Skid-mounted heaters utilize separate heating tubes and heat sinks. Through the collaboration of temperature control devices and temperature sensors, the temperature is consistently maintained within the set range. These skid-mounted heaters offer energy-saving, high efficiency, easy installation, a compact footprint, and a long service life.

[0003] Existing skid-mounted heaters utilize a highly dense, flanged heating tube within a heating tube, controlled by a power distribution box. These heaters offer advantages such as rapid heating, uniform heating, good heat dissipation, and high thermal efficiency. However, they lack a pressure relief function. This causes a rapid increase in pressure within the heating tube after heating. If this pressure exceeds the compressive strength of the heating tube, there is a risk of explosion, and safety issues remain. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 3 The utility model provides a skid-mounted heater that can relieve pressure and is explosion-proof, comprising a support frame 2 and a heating tube 1 connected to the top of the support frame 2, the end of the heating tube 1 being connected to a heating head 3, and the heating head 3 being connected to a heating tube. A pressure relief port 5 is provided on the top of the heating tube 1, the pressure relief port 5 being connected to a pressure relief tube 4, the pressure relief tube 4 being connected to a blocking mechanism for blocking the pressure relief port 5, the blocking mechanism comprising a lifting column 13, a lifting disk 17, a spring 20, and a plug 21, the lifting disk 17 being movably connected to the pressure relief tube 4, the two ends of the spring 20 being connected to the lifting disk 17 and the plug 21, the plug 21 being pressed against the inner bottom end of the pressure relief tube 4, the plug 21 being able to block the pressure relief port 5, so that the interior of the heating tube 1 is in a closed environment, facilitating rapid heating. A knocking reminder mechanism is connected to the top of the lifting column 13, a driving mechanism for driving the lifting disk 17 to rise and fall is connected to the outer side of the pressure relief tube 4, and an exhaust port 6 is connected to the pressure relief tube 4.

[0020] When the internal pressure of the heating tube 1 rises to a certain value, the plug 21 can be lifted, and the gas can be transported into the pressure relief tube 4 and discharged from the exhaust port 6, thereby achieving the purpose of good pressure relief and preventing the risk of explosion. At the same time, the rise of the plug 21 synchronously drives the lifting column 13 to rise, and the spring 20 is compressed. When it reaches a certain deformation, it drives the plug 21 downward, synchronously driving the lifting column 13 downward, causing the lifting column 13 to perform a lifting action. Combined with the use of the rocker 12 and the torsion spring, the knocking head 15 repeatedly strikes the striking plate 16. As the air pressure increases, the knocking sound becomes more prominent, serving as a good reminder.

[0021] A sealing surface 22 is provided at the inner bottom end of the pressure relief cylinder 4 . The sealing surface 22 matches the plug 21 , thereby improving the sealing performance of the connection between the plug 21 and the pressure relief cylinder 4 .

[0022] A spring groove is provided on the top of the plug 21 , and both ends of the spring 20 are fixedly connected to the spring groove and the lifting plate 17 , and the spring 20 is sleeved on the lifting column 13 .

[0023] The knocking reminder mechanism includes a seesaw 12, a support plate 14, a knocking head 15, and a striking plate 16. The support plate 14 is used to support the seesaw 12. The knocking head 15 is connected to the end of the seesaw 12 and matches the striking plate 16. The top of the lifting column 13 is connected to the seesaw 12, and the bottom of the support plate 14 is fixedly connected to the top cover 11. The top of the support plate 14 is rotatably connected to the seesaw 12 via a torsion spring shaft. The torsion spring allows the seesaw 12 to fit the top of the lifting column 13. When the lifting column 13 rises, the top of the lifting column 13 slides on the seesaw 12, lifting one end of the seesaw 12. The knocking head 15 at the other end knocks the striking plate 16, and the torsion spring is further coiled. When the lifting column 13 descends, the torsion spring drives one end of the seesaw 12 downward, separating the knocking head 15 at the other end from the striking plate 16, causing the knocking head 15 to repeatedly knock the striking plate 16, thus providing a good reminder. When the air pressure is further increased, the lifting amplitude of the plug 21 increases, so that the striking force of the striking head 15 on the striking plate 16 increases and the striking frequency also increases, thereby enhancing the reminder effect.

[0024] The top of the pressure relief cylinder 4 is connected to the top cover 11 , the lifting column 13 passes through the lifting plate 17 and the top cover 11 , and the hitting plate 16 is connected to the top of the top cover 11 .

[0025] The driving mechanism includes a lifting seat 7, a mounting plate 8, a stud 9, a rotating handle 10, a connecting block 18, and a threaded groove 19. The lifting seat 7 is movably connected to the outside of the pressure relief cylinder 4. The connecting block 18 is fixedly connected to the lifting plate 17 and the lifting seat 7. The threaded groove 19 is set in the lifting seat 7 and is connected to the stud 9. The rotating handle 10 is used to drive the stud 9 to rotate. The stud 9 is rotatably connected to the mounting plate 8, and the mounting plate 8 is connected to the top cover 11. The rotatable rotating handle 10 drives the stud 9 to rotate. The stud 9 and the threaded groove 19 work together to achieve the lifting and lowering of the lifting seat 7. The lifting seat 7 can drive the lifting plate 17 to rise and fall, thereby controlling the deformation of the spring 20 and the pressure applied to the plug 21. This facilitates the adjustment of the pressure relief valve value and has strong applicability.

[0026] The turning handle 10 is connected to the end of the stud 9 , and the stud 9 is threadedly connected to the thread groove 19 .

[0027] Working principle: When the internal air pressure of the heating tube 1 rises to a certain value, the plug 21 can be lifted up to discharge the gas from the exhaust port 6 to achieve the purpose of pressure relief. When the plug 21 rises, the spring 20 is compressed. After being compressed to a certain amount, the plug 21 can be driven to move downward, that is, the lifting column 13 can perform a lifting action, and then combined with the use of the seesaw 12 and the torsion spring, the knocking head 15 can repeatedly hit the beating plate 16, and as the air pressure increases, the knocking sound becomes more obvious, which serves as a good reminder. The handle 10 can be manually rotated to drive the stud 9 to rotate, and then combined with the use of the threaded groove 19, the lifting seat 7 can be lifted and lowered, and the lifting disk 17 can be driven to lift and lower synchronously, so that the deformation of the spring 20 can be controlled, and pressure control is applied to the plug 21, which is convenient for adjusting the pressure relief valve value, and has strong applicability.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
