Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fuel filling pipelines, and particularly to a fuel filling pipeline device for a cooling tower. Background Art
[0002] In daily industrial production, a cooling tower is one of the common and even indispensable devices. The cooling tower plays a role in cooling the water temperature of industrial water. Since the motor fan bearings of the cooling tower run for 24 hours, the wear on itself is also large. Over time, it is easy to cause damage due to lack of oil in the motor and fan. Therefore, the cooling tower must be regularly inspected for oil level to prevent damage to its operation caused by lack of oil. The working principle of the cooling tower determines that it must be built at a height of more than ten meters or dozens of meters to create a water flow drop to achieve the purpose of cooling the water body.
[0003] Therefore, to ensure the normal operation of the cooling tower, when the oil level is insufficient, it is necessary to add oil in time. Adding oil to the top of the cooling tower has become a relatively heavy physical activity. Normally, a crane is used to lift the oil barrel onto the cooling tower, and then manually divided into small oil barrels and added to the fuel filling pipeline through a funnel. In addition, the fuel filling pipelines of the existing technologies are basically made of steel pipes, and it is impossible to directly see the oil level during the fuel filling process, which easily leads to oil spillage or inability to judge whether the appropriate oil level has been reached. Such an operation is not only cumbersome but also easily causes oil waste and consumes time.
[0004] In view of this, it is necessary to propose a fuel filling pipeline device for a cooling tower to solve or at least alleviate the above defects. Summary of the Utility Model
[0005] In order to solve the problems that the existing device is not easy to operate and is prone to oil waste, the utility model provides a fuel filling pipeline device for a cooling tower.
[0006] The utility model is implemented as follows:
[0007] A fuel filling pipeline device for a cooling tower includes a fuel filling pipeline. A vertical oil injection pipe is provided on the outer wall of the fuel filling pipeline. The top end of the vertical oil injection pipe is threadedly connected with a connection cover. The vertical oil injection pipe is connected with an extraction device through the connection cover. The extraction device includes a fuel pump, an oil outlet elbow, an oil inlet hose and a filter element. The output end of the fuel pump is communicated with the oil outlet elbow. One end of the oil outlet elbow penetrates through the connection cover and is communicated with an oil discharge pipe. A liquid level sensor is sleeved on the outer wall of the oil discharge pipe. An oil outlet hole is opened at the bottom end of the outer wall of the oil discharge pipe. The input end of the fuel pump is communicated with the oil inlet hose. One end of the oil inlet hose is connected with the filter element.
[0008] Further, the fuel filling pipeline includes a pipeline body, a docking seat and a rotary joint. One end of the pipeline body is provided with the docking seat. The pipeline body is rotationally communicated with one end of the rotary joint through the docking seat.
[0009] The beneficial effect of adopting the above further solution is that through the connection and use of the docking seat, while the pipeline body and the adapter pipe form a communication relationship, they can also rotate.
[0010] Further, the outer wall of the adapter pipe is communicated with the bottom end of the oil injection vertical pipe.
[0011] The beneficial effect of adopting the above further solution is that through the communication between the oil injection vertical pipe and the adapter pipe, the oil injection vertical pipe can swing circumferentially around the docking seat, thereby facilitating the adjustment of the angle.
[0012] Further, a sealing cover is provided at the top end of the oil injection vertical pipe. The sealing cover includes a cover body, a vertical rod and a scale line. The cover body is threadedly connected to the top end of the oil injection vertical pipe, and the vertical rod is connected to the bottom end of the cover body.
[0013] The beneficial effect of adopting the above further solution is that through the threaded connection of the cover body, the cover body can drive the vertical rod to be disassembled.
[0014] Further, one end of the vertical rod extends into the interior of the oil injection vertical pipe and a scale line is provided.
[0015] The beneficial effect of adopting the above further solution is that through the setting of the scale line, when the vertical rod touches the oil and adheres to the oil stain, the oil volume inside the oil injection vertical pipe can be detected.
[0016] Further, the connection cover includes an end cover, a square hole, a round hole and a filter screen. Square holes and round holes are respectively provided at the top end of the end cover.
[0017] Further, the interior of the round hole is combined with the outer wall of the oil outlet elbow pipe.
[0018] The beneficial effect of adopting the above further solution is that through the setting of the square hole, the end cover can complete the insertion and docking with the oil outlet elbow pipe.
[0019] Further, a filter screen is installed inside the square hole.
[0020] The beneficial effect of adopting the above further solution is that through the setting of the square hole, it provides space for the installation of the filter screen, thereby facilitating the maintenance of the stable air pressure inside and outside the oil injection vertical pipe.
[0021] Further, the liquid level sensor and the oil pump are respectively electrically connected to a controller and are controlled by the controller.
[0022] The beneficial effect of adopting the above further solution is that through the signal conversion of the controller, it can convert the signals between the liquid level sensor and the oil pump, so that once the liquid level sensor acts, it will directly cause the oil pump to stop operating.
[0023] The beneficial effects of the present utility model are as follows: Through the coordinated use of the oil injection vertical pipe, connection cover, extraction device, drain pipe, liquid level sensor, and oil outlet hole, the device can automatically stop adding oil when the required liquid level is reached, without causing waste due to uncontrollable overflow of oil and reducing labor. Among them, through the installation and use of the oil pump, the inlet hose can absorb oil from the inside of the oil barrel and cooperate with the filtering function of the filter element to reduce impurities in the oil. Then, through the use of the oil outlet elbow, it is convenient to transport the oil extracted by the oil pump into the drain pipe, until the oil is transported into the oil injection vertical pipe and flows into the fuel filling pipeline. Furthermore, through the installation and use of the liquid level sensor, it can detect the oil content inside the oil injection vertical pipe, and once the liquid level sensor operates, it will directly prompt the oil pump to stop operating.

The technical means that once the liquid level sensor 700 acts, it will directly cause the oil pump 4001 to stop operating is a mature technical means in the prior art and will not be elaborated here.
[0039] Specifically, the working principle of the fuel filling pipeline device for the cooling tower: During use, first, check whether the structure of the device is intact. After ensuring the integrity of the structure, then put it into use. Among them, by starting the oil extraction pump 4001, the output end thereof enables the oil inlet hose 4003 to absorb oil from the inside of the oil barrel, and cooperate with the filtering function of the filter element 4004 to reduce impurities in the oil. Then, by using the oil outlet elbow 4002, it is convenient to transport the oil extracted by the oil extraction pump 4001 into the inside of the drain pipe 600 until the oil is transported into the inside of the oil injection vertical pipe 200 and flows into the inside of the fuel filling pipeline 100. Then, by installing and using the liquid level sensor 700, it can detect the oil content inside the oil injection vertical pipe 200. Once the liquid level sensor 700 acts, it will directly cause the oil extraction pump 4001 to stop operating. And by using the connection of the docking seat 1002, while the pipeline body 1001 and the adapter pipe 1003 form a communication relationship, they can also rotate. At the same time, through the communication between the oil injection vertical pipe 200 and the adapter pipe 1003, the oil injection vertical pipe 200 can swing circumferentially around the docking seat 1002, so as to facilitate angle adjustment. Then, by setting the square hole 3002, it provides space for the installation of the filter screen 3004, so as to facilitate maintaining the stability of the air pressure inside and outside the oil injection vertical pipe 200.
[0040] It should be noted that the specific model specifications of the oil extraction pump 4001 and the liquid level sensor 700 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.
[0041] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
