Description

Technical Field

[0001] This utility model belongs to the field of heat transfer oil cooling technology, specifically, it relates to a heat transfer oil circulating cooling device. Background Technology

[0002] Thermal oil circulating pumps are high-temperature fluid transport equipment, transporting fluids with temperatures up to 320°C. The shaft seals and drive shaft bearings of thermal oil circulating pumps require lubricating oil or lubricating fluid as lubricants during operation to meet the lubrication needs of the shaft seals or bearings. The working temperature of the lubricant should not be too high, generally less than 70°C. Therefore, a cooling device needs to be installed in the thermal oil circulating pump to cool the lubricant.

[0003] Existing technologies generally use industrial circulating cooling water to cool the lubricant of heat transfer oil circulating pumps. However, industrial circulating cooling water has a high salt content and particulate matter content. When the temperature is above 45°C, it is easy to form scale and block the cooling water flow channel, which in turn leads to excessively high temperature of the shaft seal lubricant of the heat transfer oil circulating pump, shaft seal failure, and fluid leakage. At the same time, excessively high temperature will also affect the working quality and service life of the bearing. In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figures 1 to 5 This utility model provides a technical solution: a heat transfer oil circulation cooling device, including a hot oil circulation pump body 1, a bearing 3, a cooling jacket 2, a coolant tank 6 and a pretreatment tank 9. The output shaft of the hot oil circulation pump body 1 is fitted with a drive structure. The cooling jacket 2 is provided inside the housing of the drive structure. The middle part of the cooling jacket 2 is provided with a reserved groove for the bearing 3 to be placed. The bearing 3 is fitted outside the output shaft of the hot oil circulation pump body 1. The cooling jacket 2 has a cooling cavity inside. The inlet pipe 4 and the outlet pipe 5 are respectively connected to the two sides of the cooling cavity. The inlet pipe 4 is connected to the liquid storage cavity inside the coolant tank 6 at the upper end of the drive structure housing.

[0029] The inlet pipe 4 is connected to the output end of the first micro circulation pump 7 inside the coolant tank 6. The other end of the first micro circulation pump 7 passes through the horizontal plate in the middle of the coolant tank 6 through a pipe and extends into the interior of the liquid storage chamber. One side of the liquid storage chamber is connected to the pre-treatment box 9 at the upper end of the hot oil circulation pump body 1 through the recovery pipe 8. The interior of the pre-treatment box 9 is divided into multiple chambers by a cross partition 10. One of the chambers is equipped with multiple filter pipes 11. The multiple filter pipes 11 are connected to each other through a C-shaped pipe 12. The top of the outermost filter pipe 11 is connected to a water inlet pipe 13. The upper end of the innermost filter pipe 11 is connected to a second micro circulation pump 14 through a pipe. The output end of the second micro circulation pump 14 passes through the coolant tank 6 through the liquid exchange pipe 15. The middle of the liquid exchange pipe 15 is equipped with a first control valve 16.

[0030] Each filter tube 11 has a symmetrically fixed positioning ring 17 inside, and a filter element 18 is provided between every two positioning rings 17. Each positioning ring 17 has a reserved hole in the middle for liquid flow, and a filter screen 19 is provided in the middle of each reserved hole. Considering that industrial circulating cooling water is generally used to cool the lubricant of the heat transfer oil circulating pump, but the industrial circulating cooling water has a high salt content and particulate matter content, and when the temperature is higher than 45°C, it is easy to form scale and block the cooling water flow channel, which will lead to the shaft seal lubricant temperature of the heat transfer oil circulating pump being too high, shaft seal failure and fluid leakage. At the same time, the high temperature will also affect the working quality and service life of the bearing 3. This utility model will use a pre-treatment box 9 to pre-treat the industrial circulating water entering the device, thereby filtering out salt particles and other particulate matter in the circulating water, thus avoiding the blockage of the circulating pipeline. That is, the cooling circulating water enters the device and passes through multiple filter tubes 11, and will be fully filtered by multiple filter screens 19 and filter elements 18 inside the filter tubes 11.

[0031] The upper end of the pretreatment box 9 is fixed with a cover plate 21 by a limiting bolt 20. A sealing ring 22 is sleeved on the outer side of the cover plate 21 and the lower end, and the sealing ring 22 abuts against the inside of the cover plate 21 and the pretreatment box 9. The sealing performance between the cover plate 21 and the pretreatment box 9 is improved by setting the sealing ring 22.

[0032] One of the chambers inside the pretreatment tank 9 is used to hold waste liquid. A liquid level sensor 23 is installed on one side of the upper end of the cross-shaped partition 10, and the detection end of the liquid level sensor 23 extends through to the lower end of the cross-shaped partition 10 and is located in the chamber used to hold waste liquid. By setting up the liquid level sensor 23, the user can easily know the liquid level in the chamber used to hold waste liquid, which is beneficial for subsequent discharge. Discharge will be carried out using the drain valve connected to the front of the chamber. (See reference...) Figure 2 Know the location of the drain valve.

[0033] Among them, a third micro circulation pump 24 is provided on one side of the liquid level sensor 23. The liquid outlet of the third micro circulation pump 24 is connected to the cavity for holding waste liquid through a pipe. The negative pressure end of the third micro circulation pump 24 is connected to the recovery pipe 8. A third control valve 25 is provided in the middle of the recovery pipe 8. By setting the recovery pipe 8 in conjunction with the third micro circulation pump, the coolant in the coolant tank 6 can be replaced periodically.

[0034] An infrared temperature sensor 26 for detecting the temperature of bearing 3 is fixed on one side of the cooling jacket 2. The infrared temperature sensor 26 is used to detect the working temperature of bearing 3.

[0035] The upper end of the horizontal plate is fixed with a cooling conductor. The bottom of the cooling conductor extends through to the lower end of the horizontal plate and is located inside the liquid storage chamber. The upper end of the cooling conductor is attached to the cooling end of the semiconductor cooling chip through thermal grease. The heating end of the semiconductor cooling chip is attached to the heat dissipation fins through thermal grease. A mounting bracket is provided above the heat dissipation fins. Multiple cooling fans are installed in the middle of the mounting bracket. A dustproof net 31 is provided above the cooling fans and is installed on the top of the coolant tank 6. By setting up the semiconductor cooling chip and the cooling conductor to work together, the cooling circulating fluid in the coolant tank 6 is cooled, thereby ensuring that the temperature of the coolant is lower than the temperature transmitted to the bushing when the bearing 3 is working, so as to ensure the cooling effect of the bearing 3 and avoid the bearing 3 overheating and affecting the normal use of the lubricant.

[0036] The semiconductor cooling chip is equipped with an implantable temperature sensor and a water quality detector 33 on both sides. The detection ends of the implantable temperature sensor and the submersible liquid level sensor 23 are located inside the liquid storage chamber. The water quality detector 33 is used to detect the water quality of the circulating water. When the result is abnormal or there is a risk of clogging the pipes due to the impact on circulation, the circulating water will be discharged through the recovery pipe 8 and then new circulating water will be injected through the liquid replacement pipe 15 for use.

[0037] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
