Description

Technical Field

[0001] The utility model relates to a Roots blower, in particular to a water-cooled Roots blower oil tank. Background Art

[0002] Roots blower is a positive displacement blower that mainly relies on the relative movement of two blade-shaped rotors in the cylinder to compress and transport gas, thereby achieving gas compression and transportation. It has a simple structure and is easy to manufacture. It is widely used in aquaculture oxygenation, sewage treatment aeration, cement transportation and other fields.

[0003] During the long-term operation of the Roots blower, the temperature of the whole machine will increase significantly. Excessive temperature will directly shorten the service life of the internal parts of the Roots blower. At present, the heat dissipation problem of the Roots blower is usually solved by a combination of passive heat dissipation and active heat dissipation. Passive heat dissipation is to circulate lubrication of the internal parts of the blower through the lubricating oil in the oil tank. During the circulating lubrication process, part of the heat on the internal parts of the blower will be taken away to achieve passive heat dissipation. Active heat dissipation is to install a cooling fan on the outside of the oil tank to cool the oil tank with air, thereby reducing the temperature of the lubricating oil in the oil tank, thereby ensuring the efficiency of passive heat dissipation of the lubricating oil. However, since active heat dissipation mainly acts on the external shell of the oil tank, it is impossible to quickly dissipate and cool the lubricating oil in the oil tank, and the heat dissipation efficiency is low. Ultimately, it is difficult to meet the rapid heat dissipation needs of the internal parts of the Roots blower. In addition, installing a cooling fan will increase the floor space of the blower. Utility Model Content

[0004] In view of the above technical problems, the utility model provides a water-cooled Roots blower oil tank. The water-cooled Roots blower oil tank can achieve rapid water cooling of the oil tank as a whole and the lubricating oil in the oil tank by opening a circulating water channel inside the oil tank outer shell, thereby extending the service life of the internal parts of the blower. Moreover, since no external cooling fan or other heat dissipation facilities are required, the floor space of the blower will not be increased.

[0005] To this end, the technical solution of the utility model is a water-cooled Roots blower oil tank, which is provided with an oil tank body, the oil tank body comprising an oil tank inner cavity and an oil tank outer shell, the oil tank inner cavity is filled with lubricating oil, the top end of the oil tank body is provided with an oil filling port, the bottom end of the oil tank body is provided with an oil discharge port, the oil filling port and the oil discharge port are respectively communicated with the oil tank inner cavity;

[0006] A circulating water channel is provided inside the outer shell of the fuel tank, and the circulating water channel includes a circulating water channel water inlet and a circulating water channel water outlet, the circulating water channel water inlet and the circulating water channel water outlet are respectively located at two ends of the circulating water channel, and the circulating water channel water inlet and the circulating water channel water outlet penetrate to the outside of the fuel tank body;

[0027] The utility model is further described below in conjunction with embodiments.

The oil tank inner cavity 101 is filled with lubricating oil. An oil filling port 11 is provided at the top of the oil tank body 1, and an oil discharge port 12 is provided at the bottom of the oil tank body 1. The oil filling port 11 and the oil discharge port 12 are respectively connected with the oil tank inner cavity 101. Before the blower is operated, the lubricating oil is injected into the oil tank inner cavity 101 from the oil filling port 11 to lubricate and cool the internal components of the blower. When the lubricating oil needs to be discharged, the lubricating oil is discharged to a designated position through the oil discharge port 12 to complete the discharge of the lubricating oil.

[0029] A circulating water channel 9 is provided inside the oil tank outer shell 102, and the circulating water channel 9 includes a circulating water channel water inlet 903 and a circulating water channel water outlet 904, which are respectively located at the two ends of the circulating water channel 9, and the circulating water channel water inlet 903 and the circulating water channel water outlet 904 penetrate to the outside of the oil tank body 1, and cooling water flows in from the circulating water channel water inlet 903, and then flows out from the circulating water channel water outlet 904 through the circulating water channel 9, and the effect of continuously reducing the temperature of the lubricating oil in the oil tank outer shell 102 and the oil tank inner cavity 101 is achieved through the circulation of cooling water.

[0030] A guide camber 901 is provided on the bottom end surface of the circulating water channel 9 near the circulating water channel water inlet 903, and the bending direction of the guide camber 901 is toward the direction of the circulating water channel water inlet 903. A rounded corner 902 is provided on the top position of the circulating water channel 9 near the circulating water channel water inlet 903. By setting the guide camber 901, after the cooling water flows into the circulating water channel water inlet 903, the cooling water can be quickly guided to the inside of the circulating water channel 9 through the guiding effect of the guide camber 901, thereby improving the smoothness of the cooling water flowing in the circulating water channel 9 and avoiding After the cooling water enters from the circulating water channel water inlet 903, it impacts the position on the circulating water channel 9 located at the front end of the circulating water channel water inlet 903. Long-term impact will cause varying degrees of damage to the surface of the circulating water channel 9, and ultimately reduce the smoothness of the flow of cooling water in the circulating water channel 9. At the same time, the noise of the blower during operation will also increase significantly. The function of the rounded corners 902 is also to increase the smoothness of the flow of cooling water in the circulating water channel 9, play a certain role in guiding and draining, and reduce the resistance of cooling water when passing through the circulating water channel water inlet 903.

[0031] A guiding arc surface 901 is provided on the bottom end surface of the circulating water channel 9 near the circulating water channel outlet 904, and the bending direction of the guiding arc surface 901 is toward the direction of the circulating water channel outlet 904. A rounded corner 902 is provided at the top position of the circulating water channel 9 near the circulating water channel outlet 904. The function of the guiding arc surface 901 is the same as that of the guiding arc surface 901 on the side of the circulating water channel inlet 903, both of which are guiding functions, which can ensure that the cooling water flowing out of the circulating water channel 9 can smoothly flow out of the circulating water channel outlet 904, thereby avoiding the cooling water from causing impact damage to the side wall of the circulating water channel 9.

[0032] An oil filling port connecting flange 2 is fixedly provided at the position of the oil filling port 11 on the outside of the oil tank body 1, and the oil filling port connecting flange 2 is connected to the oil filling port 11; an oil discharge port connecting flange 3 is fixedly provided at the position of the oil discharge port 12 on the outside of the oil tank body 1, and the oil discharge port connecting flange 3 is connected to the oil discharge port 12; an inlet connecting flange 4 is fixedly provided at the position of the circulating water channel inlet 903 on the outside of the oil tank body 1, and the inlet connecting flange 4 is connected to the circulating water channel inlet 903; a water outlet connecting flange 5 is fixedly provided at the position of the circulating water channel outlet 904 on the outside of the oil tank body 1, and the water outlet connecting flange 5 is connected to the circulating water channel outlet 904.

In addition, according to the actual needs of the blower, a cooling device is installed at the water inlet connecting flange 4 or the water outlet connecting flange 5 to cool the cooling water, so as to increase the cooling effect of the blower. In addition, an oil drain connecting flange 3 is set at the position of the oil drain port 12, so that the lubricating oil can be discharged to a designated area or a designated container for storage, so as to avoid the lubricating oil being discharged into the external environment and polluting the external environment.

[0034] The oil filling port 11 is located in the middle of the top of the oil tank body 1, and the circulating water channel water inlet 903 and the circulating water channel water outlet 904 are respectively located on both sides of the oil filling port 11. This structural arrangement can reduce the difficulty of processing the circulating water channel 9 and avoid interference in the processing position. It can also ensure that the circulating water channel 9 has sufficient coverage of the oil tank outer shell 102, thereby increasing the cooling effect of the cooling water on the oil tank outer shell 102.

[0035] Lifting seats 6 are fixedly provided on both sides of the outside of the oil tank body 1 near the upper end. The lifting seats 6 are respectively located outside the circulating water channel inlet 903 and the circulating water channel outlet 904. Through the lifting seats 6, the blower can be hoisted, which is convenient and quick to operate with high work efficiency.

[0036] Positioning seats 7 are fixedly provided on both sides of the outside of the oil tank body 1 near the middle, and positioning holes 701 are provided on the positioning seats 7. By setting the positioning seats 7, the oil tank body 1 and the wall panel can be quickly positioned and installed. Specifically, when installing the oil tank body 1 and the wall panel, first align the positioning seats 7 on the oil tank body 1 with the corresponding positioning seats on the wall panel, and pass the locking screws through the positioning holes 701 to preliminarily position the oil tank body 1 and the wall panel. Then, the oil tank body 1 and the wall panel are subsequently assembled, which shortens the operation time and improves work efficiency.

[0037] An oil mark window 8 is provided on the oil tank body 1, through which the remaining amount and cleanliness of the lubricating oil in the oil tank inner cavity 101 can be checked in real time.

[0038] A filter screen 10 is fixedly provided between the water inlet connecting flange 4 and the circulating water inlet 903, and a filter screen 10 is fixedly provided between the oil filling port connecting flange 2 and the oil filling port 11. By setting the filter screen 10, impurities in the cooling water and the lubricating oil can be filtered to ensure that the cooling water and the lubricating oil are of sufficient cleanliness.

[0039] The oil filling port connecting flange 2, the water inlet connecting flange 4, the water outlet connecting flange 5, the oil drain port connecting flange 3, the lifting seat 6 and the positioning seat 7 are fixed to the tank body 1 by welding, which can increase the impact strength of the corresponding positions and improve the overall rigidity of the tank body 1.

[0040] The water-cooled Roots blower oil tank has a circulating water channel 9 provided inside the oil tank outer shell 102, in which cooling water circulates. During the circulation of the cooling water, most of the heat on the oil tank outer shell 102 is taken away, and the oil tank outer shell 102 is continuously cooled down. After the oil tank outer shell 102 is cooled down, the lubricating oil in the oil tank inner cavity 101 is also cooled down rapidly. At this time, while the lubricating oil circulates and lubricates the internal parts of the blower, most of the heat on the internal parts of the blower is taken away. The cycle of this cooling method will continuously reduce the temperature of the blower outer shell 102, the internal parts and the internal related chambers, thereby ensuring that the blower is continuously in the optimal operating temperature range, further ensuring the stability of the blower for long-term operation, and extending the service life of the internal parts of the blower.
