Description

Technical Field

[0001] This utility model relates to the field of steam heater technology, and in particular to a waterless heater for storage tanks. Background Technology

[0002] A steam heater for storage tanks is a key piece of equipment used to heat the liquid inside the tank. Its main purpose is to increase the temperature of the medium inside the tank through the heat transfer effect of steam to meet the transportation, storage, or process requirements in industrial production. Efficient heat exchange is achieved through convection and conduction between the steam and the liquid inside the tank.

[0003] In practical applications, steam heaters can effectively solve temperature control problems in various industrial scenarios. For high-viscosity liquids (such as heavy oil, asphalt, resins, etc.), heating can significantly reduce viscosity, ensuring good pumpability and flowability of the fluid; for easily solidified media (such as waxes, certain chemicals), heating can prevent crystallization or solidification, ensuring production continuity; in the petrochemical field, steam heating can also promote certain process reactions or maintain the stability of raw materials.

[0004] In existing technologies, when high-temperature steam enters the heating coil, it quickly condenses into water upon encountering the cold liquid. If the condensate cannot be discharged in time, the steam will push the accumulated water to flow at high speed, impacting the pipe wall or valve and causing water hammer. Long-term water hammer can cause severe vibration of the pipeline, leading to loosening or fatigue fracture of the supporting structure. Therefore, we propose a water hammer-free heater for storage tanks to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waterless heater for storage tanks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A waterless heater for a storage tank includes a storage tank body. A water storage pipe is fixedly embedded in the bottom of the storage tank body. A hollow top plate is fixedly connected to the inner wall of the storage tank body. Multiple steam heating pipes are fixedly interconnected between the water storage pipe and the top plate. A steam inlet pipe is fixedly interconnected to the outer wall of the water storage pipe. A circular hole is opened at the top of the storage tank body. A steam outlet pipe is fixedly connected to the inner wall of the circular hole. The bottom of the steam outlet pipe is fixedly interconnected with the top of the top plate. A support rod is fixedly connected inside the water storage pipe. A sliding hole is opened on the outer wall of the support rod. A vertical pipe is slidably connected to the inner wall of the sliding hole. A metal float is fixedly connected to the top of the vertical pipe. A sleeve is fixedly connected inside the water storage pipe. A drainage component is provided inside the sleeve.

[0008] Preferably, the drainage assembly includes a hollow metal piston, the inner wall of the sleeve is slidably connected to the outer wall of the metal piston, a traction rope is fixedly connected to the top of the metal piston, the top of the traction rope is fixedly connected to the bottom of the vertical pipe, and multiple strip-shaped drainage holes are opened on the outer wall of the sleeve, so as to discharge condensate by setting the drainage assembly.

[0009] Preferably, the outer wall of the storage tank body is provided with a through hole, the inner wall of the through hole is fixedly connected to the outer wall of the steam inlet pipe, and a steam generator is fixedly connected to one end of the steam inlet pipe. The steam generator uses fuel or other energy to heat water to a high temperature to generate steam.

[0010] Preferably, the top of the sleeve is provided with a docking hole, and the inner wall of the docking hole is slidably connected to the outer wall of the traction rope, so that the metal piston can be moved by setting the traction rope.

[0011] Preferably, a condensate outlet pipe is fixedly connected to the bottom of the water storage pipe, and a glass tube is fixedly connected to the outer wall of the water storage pipe. The outer end of the glass tube is sealed. When the condensate is not discharged, the condensate level rises, causing condensate to remain in the glass tube, which can prompt the operator to perform timely maintenance on the water storage pipe.

[0012] Preferably, the bottom of the storage tank body is fixedly connected to multiple legs, and the top of the storage tank body is fixedly connected to a material pipe, with the multiple legs supporting the storage tank body.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] This solution ensures timely drainage of condensate by setting up a water storage pipe, support rod, vertical pipe, metal float, sleeve, metal piston, traction rope, strip-shaped drainage hole and condensate outlet pipe. This prevents water hammer caused by steam pushing high-speed water flow to impact the pipe wall due to water accumulation. Furthermore, it requires no additional power and achieves automatic drainage by relying on changes in condensate level and gravity. The structure is simple, easy to maintain, and operates stably and reliably. Attached Figure Description

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1-4 As shown, a waterless heater for a storage tank is disclosed, comprising a storage tank body 1, a water storage pipe 2 fixedly embedded in the bottom of the storage tank body 1, a hollow top plate 3 fixedly connected to the inner wall of the storage tank body 1, a plurality of steam heating pipes 4 fixedly interconnected between the water storage pipe 2 and the top plate 3, the steam in the steam heating pipes 4 heating the medium in the storage tank body 1, a steam inlet pipe 5 fixedly interconnected to the outer wall of the water storage pipe 2, a through hole opened on the outer wall of the storage tank body 1, the inner wall of the through hole being fixedly connected to the outer wall of the steam inlet pipe 5, and a steam generator (WDR) fixedly interconnected to one end of the steam inlet pipe 5.

[0023] The top of the storage tank body 1 has a round hole, and a steam exhaust pipe 6 is fixedly connected to the inner wall of the round hole. The bottom of the steam exhaust pipe 6 is fixedly connected to the top of the top plate 3. The steam after heat exchange is discharged from the top plate 3 and the steam exhaust pipe 6. A support rod 7 is fixedly connected inside the water storage pipe 2. A sliding hole is opened on the outer wall of the support rod 7. A vertical pipe 8 is slidably connected to the inner wall of the sliding hole. A metal float 9 is fixedly connected to the top of the vertical pipe 8. The metal float 9 moves up and down through the vertical pipe 8 and the sliding hole.

[0024] The water storage pipe 2 is fixedly connected to the sleeve 10. The top of the sleeve 10 has a docking hole. The inner wall of the docking hole is slidably connected to the outer wall of the traction rope 12. The bottom of the water storage pipe 2 is fixedly connected to the condensate outlet pipe 14. The outer wall of the water storage pipe 2 is fixedly connected to the glass tube 17. The glass tube 17 serves as a warning and reminder to ensure timely maintenance and avoid equipment damage.

[0025] The casing 10 is equipped with a drainage assembly, which includes a hollow metal piston 11. The metal piston 11 moves up and down along the casing 10. The inner wall of the casing 10 is slidably connected to the outer wall of the metal piston 11. A traction rope 12 is fixedly connected to the top of the metal piston 11. The top of the traction rope 12 is fixedly connected to the bottom of the vertical pipe 8. Multiple strip-shaped drainage holes 13 are opened on the outer wall of the casing 10. The multiple strip-shaped drainage holes 13 are arranged in a ring. When the metal piston 11 moves upward, the condensate in the water storage pipe 2 enters the casing 10 through the multiple strip-shaped drainage holes 13. Multiple legs 15 are fixedly connected to the bottom of the storage tank body 1. A material pipe 16 is fixedly connected to the top of the storage tank body 1.

[0026] Working principle: When the medium inside the storage tank 1 needs to be heated, the steam generator operates to deliver steam to the inside of the steam inlet pipe 5, and then from the steam inlet pipe 5 into the water storage pipe 2. The steam enters from the top into the inside of multiple steam heating pipes 4, and transfers heat with the storage tank 1 to heat the medium. The steam after heat exchange is discharged from the top plate 3 and the steam discharge pipe 6. The condensate produced during the cooling process flows downward by its own gravity and accumulates inside the water storage pipe 2. As the condensate inside the water storage pipe 2 rises, it drives the metal float 9 to move upward. The upward movement of the metal float 9 drives the metal piston 11 to move upward through the traction rope 12. The upward movement of the metal piston 11 exposes multiple strip-shaped drain holes 13. The condensate in the water storage pipe 2 enters the sleeve 10 from the multiple strip-shaped drain holes 13, and is then discharged from the condensate outlet pipe 14. As the liquid level of the condensate drops, it drives the metal float 9 to descend, and the metal piston 11 re-blocks the multiple strip-shaped drain holes 13 by its own gravity.
