Description

Technical Field

[0001] This utility model relates to the field of heater technology, specifically a vertical heater. Background Technology

[0002] Electric heaters are used to heat, maintain, and maintain the temperature of flowing liquid and gaseous media. When the heating medium passes through the heating chamber of the electric heater under pressure, the enormous heat generated by the electric heating element is uniformly carried away by the principle of fluid thermodynamics, so that the temperature of the heated medium reaches the user's process requirements.

[0003] In related technologies, in order to improve the utilization rate of heater heat, insulation material is installed on the outer ring of the heater so that the heat is retained inside the heater as much as possible. However, after the heating medium enters the heater, it needs a certain amount of time to heat up before it can be sent out of the heater after reaching the specified temperature, which greatly reduces the heating efficiency of the heating medium. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a vertical heater that solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution:

[0006] This utility model discloses a vertical heater, including a heating cylinder and a heating part assembled at the top of the heating cylinder by bolts.

[0007] The inner conduit is spirally installed inside the heating cylinder;

[0008] The inlet port is fixedly connected to one end of the inner conduit. The heating cylinder has an installation hole corresponding to the position of the inner conduit, so that the end of the inlet port away from the inner conduit extends to the outside of the heating cylinder.

[0009] Outlet port one is fixed at the end of the inner conduit furthest from the inlet port;

[0010] The outer conduit is spirally wound around the outer wall of the heating cylinder, and one end of the outer conduit is connected to the inlet port;

[0011] The second outlet is fixed at the end of the external conduit furthest from the inlet port and is located in a different orientation from the first outlet port;

[0012] A three-way valve is installed at the connection point between the external conduit and the inlet port.

[0013] Furthermore, the bottom of the heating cylinder is fixed to the top of the base plate, and several rollers are installed on the bottom of the base plate to facilitate the movement of the heater.

[0014] Furthermore, the outer walls of the top and bottom of the heating cylinder are welded with supporting slide rails, and the supporting slide rails have several sets of sliding grooves inside.

[0015] Furthermore, mounting frames are installed inside the grooves supporting the slide rails.

[0016] Furthermore, the internal connection of the mounting frame has a mesh-like support frame.

[0017] Furthermore, both sides of the support frame are covered with thermal insulation panels.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This utility model installs an inner conduit inside the heating cylinder and an outer conduit around the outer ring of the heating cylinder. One end of the outer conduit is connected to the inner conduit through an inlet port. A three-way valve is installed inside the connection point. By adjusting the three-way valve, the flow direction of the heating medium can be changed, allowing the heating medium to be sent from outlet end two into the outer conduit. The outer conduit absorbs heat from the outer wall of the heating cylinder, thereby preheating the heating cylinder. After the preheated heating medium enters the inner conduit, it can quickly rise to the specified temperature, thereby reducing the residence time of the heating medium inside the heating cylinder and improving heating efficiency.

[0020] 2. In this invention, a heat insulation plate is installed on the outer ring of the heating cylinder and the outer conduit via a support slide rail, so that a heat insulation cavity is formed between the heating cylinder and the heat insulation plate. This can reduce the risk of being burned by high temperature and ensure that the outer conduit can receive the most sufficient heat in the heat insulation cavity. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6The heating element comprises a heating cylinder 1 and a heating section 2 assembled from the top of the heating cylinder 1 by bolts. A sealing ring is placed between the heating cylinder 1 and the heating section 2 to reduce heat loss inside the heating cylinder 1. The heating tubes of the heating section 2 are S-shaped bends, and the heating tubes are arranged at equal intervals to ensure uniform heating inside the heating cylinder 1. An inner conduit 8 is spirally installed inside the heating cylinder 1, close to the heating tubes of the heating section 2. The spiral inner conduit 8 extends the heat absorption time of the heating medium inside the heating cylinder 1. Several support rods are fixed to the inner wall of the heating cylinder 1. The inner conduit 8 is inserted into the heating cylinder 1 from the top by rotation. When the inner conduit 8 is downward, its outer wall can be flush with the heating cylinder 1. The support rods abut against each other, and as the inner conduit 8 rotates, the contact points between the inner conduit 8 and the support rods continuously change, allowing the inner conduit 8 to move downwards normally. After the inner conduit 8 moves to the appropriate position, the support rods continue to support the inner conduit 8. The inlet port 9 is fixedly connected to one end of the inner conduit 8, and the heating cylinder 1 has a mounting hole corresponding to the position of the inner conduit 8, so that the end of the inlet port 9 away from the inner conduit 8 extends to the outside of the heating cylinder 1. The outlet port 10 is fixed to the end of the inner conduit 8 away from the inlet port 9. The medium to be heated is fed into the inner conduit 8 through the inlet port 9. The heating medium absorbs heat along the inner conduit 8 inside the heating cylinder 1 and is sent out of the heating cylinder 1 through the outlet port 10. The outer conduit 11 is spirally wound around the outer wall of the heating cylinder 1. One end of the outer conduit 11 is connected to the inlet port 9, allowing the heating medium to flow inside the outer conduit 11. The outer conduit 11 absorbs heat from the outer wall of the heating cylinder 1, thus heat-treating the heating medium. The outlet end 12 is fixed at the end of the outer conduit 11 away from the inlet port 9 and is located in a different orientation from the outlet port 10. A three-way valve 13 is installed at the connection between the outer conduit 11 and the inlet port 9. The three-way valve 13 can change the flow direction of the heating medium entering the inlet port 9. Adjusting the three-way valve 13 connects the inner conduit 8 and the outer conduit 11, allowing the inlet end to flow through the inner conduit 8. One side of port 9 is closed, and outlet end 2 12 serves as the inlet of the outer conduit 11. After the heating medium enters the outer conduit 11 from outlet end 2 12, it flows to the three-way valve 13. The three-way valve 13 transfers the heating medium to the inner conduit 8. The inner conduit 8 causes the heating medium to be heated again inside the heating cylinder 1. When the heating medium is inside the outer conduit 11, the outer conduit 11 absorbs the heat emitted by the heating cylinder 1 to preheat the heating medium, so that the heating medium is heated in advance. This makes it easier for the heating medium to quickly reach the specified temperature after entering the inner conduit 8, thereby accelerating the flow of the heating medium, reducing the residence time of the heating medium inside the heating cylinder 1, and improving the heating efficiency of the heater.

[0030] The bottom of the heating cylinder 1 is fixed to the top of the base plate 3. Several rollers are installed on the bottom of the base plate 3 to facilitate the movement of the heater.

[0031] Support rails 4 are welded to the outer walls of the top and bottom of the heating cylinder 1. Several sets of grooves are opened inside the support rails 4. Mounting frames 5 are installed in the grooves of the support rails 4. A mesh-like support frame 6 is connected inside the mounting frame 5. The support frame 6 is located outside the outer conduit 11. Several mounting frames 5 are arranged in a staggered ring, so that the support frame 6 protects the outside of the heating cylinder 1 and the outer conduit 11, reducing contact between people and the heating cylinder 1 and the outer conduit 11, and reducing the risk of burns from high temperature. Both sides of the support frame 6 are covered with heat insulation plates 7. After the mounting frame 5 forms a staggered ring, the heat insulation plates 7 surround and seal the outer ring of the outer conduit 11, forming a heat insulation cavity between the heat insulation plates 7 and the heating cylinder 1, further reducing the heat loss of the heating cylinder 1. The heat in the heat insulation cavity can provide higher heat to the outer conduit 11, making the preheating of the heating medium faster. When the outer conduit 11 is inspected, the mounting frame 5 is moved along the groove opened in the support slide rail 4, so that the inspection position is quickly exposed.

[0032] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
