Technical Field
[0001] The utility model relates to the technical field of sewage pumps, in particular to a pipeline sewage pump with an oil cooling system. Background Technique
[0002] A sewage pump is a pump product in which the pump and the motor are integrated and work underwater at the same time. Compared with general horizontal pumps or vertical sewage pumps, sewage pumps have a compact structure, a small floor area, are convenient for installation and maintenance. Large sewage pumps are generally equipped with an automatic coupling device for automatic installation, and the installation and maintenance are quite convenient, and the continuous operation time is long; because the pump and the motor of the sewage pump are coaxial, the shaft is short, and the weight of the rotating parts is light, so the load (radial) borne by the bearing is relatively small, and the service life is much longer than that of general pumps. There are no problems such as cavitation damage and filling with water, especially the latter point brings great convenience to the operators, with small vibration and noise, low motor temperature rise, and no pollution to the environment; according to different sewage discharge methods, sewage pumps can be divided into self-priming sewage pumps, submersible sewage pumps, sewage pumps with knife type, and automatic stirring sewage pumps.
[0003] A pipeline sewage pump is a sewage pump that can carry out sewage treatment on pipelines. It is found that the existing pipeline sewage pumps have a high temperature during operation, so it is necessary to cool them down to ensure the stability of operation. However, the existing sewage pumps do not have corresponding heat dissipation structures, so the heat dissipation effect is limited. For this reason, we propose a pipeline sewage pump with an oil cooling system. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide a pipeline sewage pump with an oil cooling system to solve the technical problems mentioned in the above background.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A pipeline sewage pump with an oil cooling system, including a sewage pump, the sewage pump includes a pump body, and a support seat for supporting the entire sewage pump is installed below the pump body. A liquid inlet is opened on one side of the pump body, and a liquid outlet is opened on the other side of the pump body. A driving part for driving the sewage pump to operate to achieve sewage discharge of the pipeline is installed above the pump body, and a cooling box is arranged outside the driving part to realize oil cooling and temperature reduction of the driving part.
[0006] By adopting the above technical solution, the driving part of the sewage pump can be cooled by oil, thereby achieving an efficient temperature reduction effect on the driving part and ensuring the stable operation of the sewage pump.
[0007] The utility model is further arranged such that a cavity is opened inside the cooling box, and a cooling pipe wound around the outer wall of the driving part is installed in the cavity, and an oil liquid for cooling is filled in the cooling pipe.
[0008] By adopting the above technical solution, the oil cooling and temperature reduction effect on the driving part is achieved.
[0009] The utility model is further arranged such that a small pump is installed at the bottom end inside the cooling box, and a liquid outlet pipe connected to the end of the cooling pipe is connected to the output end of the small pump. The input end of the small pump is connected in a communicating manner with a liquid inlet pipe extending upward, and the top end of the liquid inlet pipe is connected in a communicating manner with a circulation box. A connecting part connected to the other end of the cooling pipe is provided at the top end of the circulation box.
[0010] By adopting the above technical solution, the liquid supply effect on the cooling pipe is achieved.
[0011] The utility model is further arranged such that an oil cavity for storing oil liquid is provided inside the circulation box, and the liquid inlet pipe and the connecting part are both communicated with the oil cavity.
[0012] By adopting the above technical solution, the circulating effect of the glaze liquid is assisted.
[0013] The utility model is further arranged such that a liquid expansion box is connected in a communicating manner to the bottom end inside the circulation box below the connecting part. The top end of the liquid expansion box is provided with a narrow opening and the bottom end is provided with a wide opening. A filter screen fixed on the inner wall of the circulation box is provided below the liquid expansion box.
[0014] By adopting the above technical solution, the heat dissipation and filtering effect of the oil liquid are achieved.
[0015] In summary, the utility model mainly has the following beneficial effects:
[0016] 1. By arranging the cooling box, the cooling pipe and the small pump, first of all, the driving part will start to drive the pump body to operate. After the pump body operates, sewage discharge inside the pipeline will be realized through the liquid inlet and outlet provided at both ends. During this process, a large amount of heat will be generated by the driving part, and the cooling box can perform oil cooling on the driving part. Specifically, the small pump will draw oil liquid from the circulation box through the liquid inlet pipe and discharge it to the cooling pipe through the liquid outlet pipe. By using the principle of heat transfer, the oil liquid in the cooling pipe can absorb the heat generated by the driving part, so as to achieve the effect of heat dissipation and temperature reduction;
[0017] 2. By setting up an oil expansion tank and a filter screen, under the action of a small pump, the oil in the cooling pipe will circulate with the oil in the circulation tank, thus realizing cyclic oil cooling and further improving the quality of oil cooling. After the oil enters the circulation tank through the connecting part, the oil will fall into the circulation tank under the action of the oil expansion tank. In this process, since the top of the oil expansion tank is narrow and the bottom is wide, when the oil is discharged from the oil expansion tank, the surface area of the unit oil volume in contact with the air will be greatly increased, thus realizing the cooling effect of the oil. And when passing through the filter screen, the oil will be filtered and purified, thus improving the quality of the oil and further enhancing the heat dissipation and cooling effect of the oil.

[0024] The embodiments of the present utility model will be described below according to its overall structure.
[0025] A pipeline sewage pump with an oil cooling system, as Figures 1-4As shown in the figure, it includes a sewage pump 1. The sewage pump 1 includes a pump body 101, and a support base 102 for supporting the entire sewage pump 1 is installed below the pump body 101. A liquid inlet 103 is provided on one side of the pump body 101, and a liquid discharge port 104 is provided on the other side of the pump body 101. A driving part 105 for driving the sewage pump 1 to operate to discharge sewage from the pipeline is installed above the pump body 101, and a cooling box 2 is arranged outside the driving part 105 to realize oil cooling and temperature reduction of the driving part 105.
[0026] Furthermore, in this embodiment, a cavity 3 is provided inside the cooling box 2, and a cooling pipe 4 wound around the outer wall of the driving part 105 is installed in the cavity 3. An oil liquid for temperature reduction is filled in the cooling pipe 4.
[0027] Please refer to Figure 3 , a small pump 5 is installed at the bottom end of the cooling box 2 inside the cooling box 2, and the output end of the small pump 5 is connected to a liquid outlet pipe 6 communicating with the end of the cooling pipe 4. The input end of the small pump 5 is connected in a communicating manner with an upward extending liquid inlet pipe 7, and the top end of the liquid inlet pipe 7 is connected in a communicating manner with a circulation box 8. A connecting part 9 communicating with the other end of the cooling pipe 4 is provided at the top end of the circulation box 8, realizing the liquid supply for the cooling pipe 4 and the overall circulation of the oil liquid.
[0028] Please refer to Figure 4 , an oil cavity 10 for storing oil liquid is provided inside the circulation box 8, and the liquid inlet pipe 7 and the connecting part 9 are both communicated with the oil cavity 10, realizing the circulation of the oil liquid.
[0029] Please refer to Figure 4 , a liquid expansion box 11 is connected in a communicating manner at the bottom end of the connecting part 9 inside the circulation box 8. The top end of the liquid expansion box 11 is provided with a narrow opening and the bottom end is provided with a wide opening. A filter screen 12 fixed on the inner wall of the circulation box 8 is arranged below the liquid expansion box 11, realizing the heat dissipation, temperature reduction, filtration and purification of the oil liquid.
[0030] The working principle of the present utility model is as follows: First, the driving part 105 is started to drive the pump body 101 to operate. After the pump body 101 operates, sewage discharge inside the pipeline is realized through the liquid inlet 102 and the liquid outlet 103 provided at both ends. During this process, a large amount of heat is generated by the driving part 105, and the cooling box 2 can perform oil cooling and temperature reduction on the driving part 105.

And when passing through the filter screen 12, the oil will be filtered and purified, so as to improve the quality of the oil and further enhance the heat dissipation and cooling effect of the oil.
