Description

Technical Field

[0001] This utility model relates to the field of diesel engine technology, specifically to an integrated fuel release and heat tracing tank for low-speed diesel engines. Background Technology

[0002] In marine low-speed diesel engine fuel drain systems, the amount of fuel drained needs to be monitored to determine the operating status of the main engine. The main principle is to introduce the drained fuel into a tank and monitor the amount of fuel drained using a level switch.

[0003] Marine low-speed diesel engines typically use heavy oil as fuel. At room temperature, heavy oil has high viscosity and poor fluidity, requiring heating before use. Currently, copper pipes carrying high-temperature steam are coiled around the surface of the venting tank to heat the released fuel. However, vibrations generated during diesel engine operation can cause these copper pipes to break over time, leading to high-temperature steam leakage and posing a significant hazard. Furthermore, during the heating process, steam condenses into water that remains inside the venting tank, impacting its lifespan.

[0004] Therefore, we propose an integrated heat tracing tank for fuel release in low-speed diesel engines. Utility Model Content

[0005] The purpose of this invention is to provide an integrated fuel release and heat tracing tank for low-speed diesel engines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated fuel release and heat tracing tank for low-speed diesel engines, comprising:

[0007] A fuel release tank, wherein a heat tracing tank is installed inside the fuel release tank, a high-temperature steam inlet pipe is fixedly connected to the top of the heat tracing tank, and a high-temperature steam outlet pipe is fixedly connected to the bottom of the heat tracing tank.

[0008] The cleaning mechanism is installed inside the heat tracing tank. The cleaning mechanism includes a drive gear. The drive gear is rotatably mounted on the back of the fuel drain tank. A first driven gear is mounted on the outside of the drive gear, and the outside of the first driven gear is meshed with the drive gear.

[0009] The recovery mechanism is installed on the back of the fuel drain tank. The recovery mechanism includes a sliding groove. The sliding groove is symmetrically opened on the back of the fuel drain tank, and a sliding block is slidably installed inside the sliding groove.

[0010] Preferably, the cleaning mechanism further includes a rotating rod, which is fixedly connected inside the first driven gear. The rotating rod passes through the interior of the heat tracing tank, and a drive gear is fixedly connected to the other end of the rotating rod. The operation of the rotating motor drives the drive gear to rotate, which in turn drives the first driven gear meshing with it to rotate. The rotation of the first driven gear drives the rotating rod to rotate, and the rotation of the rotating rod drives the drive gear to rotate.

[0011] Preferably, a first toothed ring is rotatably mounted on the inner wall of the top of the heat tracing tank, and a second toothed ring is rotatably mounted on the inner wall of the bottom of the heat tracing tank. The outer side of a drive gear meshes with both the first and second toothed rings, and a scraper is fixedly connected to the outer side of each of the first and second toothed rings. The rotation of the drive gear drives the meshing first and second toothed rings to rotate, which in turn drives the scraper to rotate. The rotation of the scraper cleans and removes the condensate that has formed on the inner wall surface of the heat tracing tank.

[0012] Preferably, a motor bracket is fixedly connected to the outside of the fuel drain tank, a rotating motor is installed on the outside of the motor bracket, and the output end of the rotating motor passes through the inside of the motor bracket and is fixedly connected to the drive gear.

[0013] Preferably, the recovery mechanism further includes a second driven gear, which is rotatably mounted on the back of the fuel drain tank. The outer side of the second driven gear meshes with the driving gear. A locking block is fixedly connected to the front end of the second driven gear, and a limiting frame is slidably mounted on the outer side of the locking block. An extension rod is fixedly connected to the bottom of the limiting frame. When the second driven gear rotates, it drives the locking block to move together. Since the locking block is inside the limiting frame, when the locking block moves, it drives the limiting frame to move together. The limiting frame moves up and down through the cooperation of a sliding groove and a sliding block. The movement of the limiting frame pulls the extension rod to move.

[0014] Preferably, a storage box is installed on the outer side of the bottom end of the extension rod, a filter plate is fixedly connected to the bottom of the extension rod, an air pump is installed on the back of the storage box, and the output end of the air pump is fixedly connected to the high-temperature steam outlet pipe. A scraper is fixedly connected to the outer side of the filter plate. The extension rod moves up and down inside the storage box, and the filter plate is used to filter and remove the condensate in the steam and store it in the storage box. When the heat tracing tank is no longer needed, the condensate in the storage box can play a role in subsequent cooling.

[0015] Preferably, a water pipe is fixedly connected to the front end of the storage tank, the other end of the water pipe is fixedly connected to the heat tracing tank, and exhaust pipes are installed on both sides of the storage tank.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: the cooperation of the active gear, the first driven gear, the rotating rod, the drive gear, the first gear ring, the second gear ring, and the scraper can promptly clean the condensate inside the heat tracing tank, effectively avoiding the decrease in thermal efficiency and energy waste caused by condensate accumulation, preventing equipment vibration, corrosion and leakage caused by water hammer effect or local overcooling, and reducing the risk of microbial growth; the cooperation of the sliding groove, the sliding block, the second driven gear, the locking block, the limiting frame, the extension rod, the storage box, and the filter plate can recover the condensate and reuse it in the cooling process, making full use of its low-temperature waste heat to replace fresh cooling water or low-temperature water source, significantly reducing the energy and water consumption of the industrial cooling system, while reducing the waste of water resources and thermal pollution caused by direct discharge of condensate.

The second driven gear 16 is driven to rotate, and the rotation of the second driven gear 16 drives the locking block 17 to move together. Since the locking block 17 is inside the limiting frame 18, when the locking block 17 moves, it drives the limiting frame 18 to move together. The limiting frame 18 moves up and down through the cooperation of the sliding groove 14 and the sliding block 15. The movement of the limiting frame 18 pulls the extension rod 19 to move.
