Description

Technical Field

[0001] The utility model relates to the technical field of generator oil tank structures, in particular to a box-type diesel generator set oil tank with a heat preservation structure. Background Art

[0002] At present, when diesel generator sets work in winter, it is difficult to start due to the low external temperature. Even some oils will become muddy or waxy due to the low temperature. One of the important reasons for the above situation is that the fuel tank does not have the performance of cold and antifreeze, so that the generator set cannot operate normally. Chinese patent application No. 201920484048.2 discloses a cold and antifreeze box-type diesel engine, which uses a layer of cavity inside the insulation shell to allow cold air to pass through a layer of buffer in the cavity. If the external cold air is too strong, the oil inside the engine tank will be frozen. First, hot water is injected into the cavity through the water inlet pipe to raise the temperature of the entire insulation shell, thereby heating the oil inside the engine tank and thawing the oil so that the engine can be used normally. This method is cumbersome to operate and requires manual addition of hot water to the cavity for thawing. It takes a long time to operate and cannot prevent the oil from becoming muddy or waxy before it becomes muddy or waxy, which affects the use of the generator set.

[0003] Therefore, it is necessary to provide a new box-type diesel generator oil tank with a thermal insulation structure to solve the above-mentioned technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a box-type diesel generator oil tank with a heat preservation structure.

[0005] The box-type diesel generator oil tank with a heat preservation structure provided by the utility model comprises an oil tank, on which a liquid storage tank for storing a pour point depressant and a liquid dropper for driving the liquid storage tank to drop the pour point depressant are installed;

[0006] The liquid dropper comprises a mounting tube, which is horizontal and fixedly mounted on the top of the oil tank through a bracket, and a threaded pipe and a liquid discharge pipe which are symmetrically arranged and coaxially distributed up and down are fixedly mounted on the mounting tube, a cylindrical valve core for blocking the threaded pipe and the liquid discharge pipe is inserted in the mounting tube, and a liquid drop hole which is radially arranged and penetrates the cylindrical valve core is opened on the cylindrical valve core;

[0007] The liquid dropper also includes a cylinder, which is fixedly mounted on the top of the oil tank through a mounting frame, and the output end of the cylinder is inserted into the mounting tube and fixedly connected to the connecting end of the cylindrical valve core;

[0008] The threaded pipe is threadedly fixedly connected to the liquid outlet of the liquid storage tank, and the drain pipe passes through the top of the oil tank and is in communication with the oil tank;

[0009] An interlayer cavity is arranged in the oil tank, and a heating pipe is installed in the interlayer cavity and is filled with heating liquid.

[0010] Preferably, a spring is also installed in the installation cylinder, one end of the spring is fixedly connected to the inner cylinder wall of the installation cylinder, and the other end of the spring is fixedly connected to the column head of the columnar valve core away from the cylinder.

[0011] Preferably, a stirring assembly is installed on the oil tank, and the stirring assembly includes a servo motor, and the servo motor is fixedly installed on the top of the oil tank through a frame, and the output end of the servo motor is fixedly connected to a stirring rod arranged in the oil tank.

[0012] Preferably, a pressure relief hole is provided at the top of the interlayer cavity.

[0013] Preferably, an explosion-proof temperature sensor for monitoring the oil temperature is installed in the oil tank, and a controller connected to the explosion-proof temperature sensor, the servo motor, the cylinder and the heating tube is installed on the oil tank.

[0014] Preferably, the outer walls of the oil tank and the liquid storage tank are covered with cold-proof felt, and an oil inlet valve is installed on the top of the oil tank.

[0015] Compared with the related art, the box-type diesel generator oil tank with thermal insulation structure provided by the utility model has the following beneficial effects:

[0016] 1. When the explosion-proof temperature sensor detects that the oil temperature is lower than the preset temperature, the cylinder opens and pushes the cylindrical valve core to slide into the installation tube. At this time, the liquid drop hole corresponds to the threaded pipe and the drain pipe, so the liquid storage tank automatically adds a pour point depressant to the oil tank. Adding an appropriate amount of pour point depressant to the oil can reduce its freezing point, thereby preventing freezing;

[0017] 2. When the explosion-proof temperature sensor of the utility model detects that the oil temperature is lower than the preset temperature, the heating tube starts to heat the heating liquid, and the heating liquid transfers the heated temperature from the oil tank to the stored oil, thereby heating the oil and accelerating the rate of preheating and thawing of the oil.

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0025] See also Figures 1 to 4 The utility model embodiment provides a box-type diesel generator oil tank with a thermal insulation structure, and the box-type diesel generator oil tank with a thermal insulation structure includes an oil tank 1, a liquid dropper 3 and a liquid storage tank 4.

[0026] In the embodiments of the present invention, please refer to Figures 1 to 4 , an explosion-proof temperature sensor 12 for monitoring the oil temperature is installed in the oil tank 1, a liquid storage tank 4 for storing a pour point depressant and a liquid dropper 3 for driving the liquid storage tank 4 to release the pour point depressant are installed on the oil tank 1, specifically, the liquid dropper 3 includes a mounting tube 31, the mounting tube 31 is horizontal and fixedly installed on the top of the oil tank 1 through a bracket, and a threaded pipe 32 and a drain pipe 33 that are symmetrically arranged and coaxially distributed are fixedly installed on the mounting tube 31, and the threaded pipe 32 and the liquid outlet of the liquid storage tank 4 are connected to each other. The outlet pipe 33 is fixedly connected with the oil tank 1 by a threaded connection, the drain pipe 33 passes through the top of the oil tank 1 and is communicated with the oil tank 1, a cylindrical valve core 34 for sealing the threaded connection pipe 32 and the drain pipe 33 is inserted in the installation tube 31, and a radially arranged liquid drop hole 34a is opened on the cylindrical valve core 34 and passes through the cylindrical valve core 34, and the liquid dropper 3 also includes a cylinder 35, the cylinder 35 is fixedly installed on the top of the oil tank 1 through a mounting frame, and the output end of the cylinder 35 is inserted into the installation tube 31 and fixedly connected to the connecting end of the cylindrical valve core 34.

[0027] It should be noted that: under normal circumstances, the cylinder 35 is in a closed state, at which time the liquid drop hole 34a on the cylindrical valve core 34 is in a misaligned state with the threaded pipe 32 and the liquid discharge pipe 33, so the threaded pipe 32 and the liquid discharge pipe 33 are in a sealed state;

[0028] When the explosion-proof temperature sensor 12 detects that the oil temperature is lower than the preset temperature, the cylinder 35 opens and pushes the cylindrical valve core 34 to slide into the mounting tube 31. At this time, the liquid drop hole 34a corresponds to the threaded pipe 32 and the drain pipe 33, so the liquid storage tank 4 automatically adds a depressant to the oil tank 1. Adding an appropriate amount of depressant to the oil can lower its freezing point, thereby preventing freezing.

[0029] Furthermore, in order to improve the stability of the cylindrical valve core 34 when it slides in the mounting cylinder 31, a spring 36 is also installed in the mounting cylinder 31, one end of the spring 36 is fixedly connected to the inner cylinder wall of the mounting cylinder 31, and the other end of the spring 36 is fixedly connected to the column head of the cylindrical valve core 34 away from the cylinder 35. Therefore, when the cylinder 35 pushes the cylindrical valve core 34 to slide in the mounting cylinder 31, the other end of the cylindrical valve core 34 has the resistance force of the spring 36, thereby greatly improving the sliding stability of the cylindrical valve core 34.

[0030] In the embodiments of the present invention, please refer to Figures 1 to 4 A stirring assembly 2 is installed on the oil tank 1, and the stirring assembly 2 includes a servo motor 21. The servo motor 21 is fixedly installed on the top of the oil tank 1 through a frame, and the output end of the servo motor 21 is fixedly connected to a stirring rod 22 arranged in the oil tank 1.

[0031] It should be noted that: when the explosion-proof temperature sensor 12 detects that the oil temperature is lower than the preset temperature, the controller 6 drives the servo motor 21 to turn on, thereby driving the stirring rod 22 to stir the oil, thereby accelerating the mixing of the falling pour point depressant and the oil, greatly reducing the freezing point of the oil. At the same time, the stirring rod 22 can also reduce the rate at which the oil becomes muddy or waxy due to low temperature.

[0032] In addition, the stirring rod 22 is made of plastic material.

[0033] In the embodiments of the present invention, please refer to Figures 1 to 4 The oil tank 1 is provided with an interlayer cavity 1a, and a heating pipe 5 is installed in the interlayer cavity 1a and is filled with heating liquid. A pressure relief hole 1b is opened at the top of the interlayer cavity 1a.

[0034] It should be noted that: when the explosion-proof temperature sensor 12 detects that the oil temperature is lower than the preset temperature, the heating pipe 5 starts to heat the heating liquid, and the heating liquid transfers the heated temperature from the oil tank 1 to the stored oil, thereby heating the oil and accelerating the rate of preheating and thawing of the oil;

[0035] In this embodiment: the specific setting temperature of the explosion-proof temperature sensor 12 is adjusted according to the actual environment, and this embodiment does not limit it;

[0036] The heating liquid may be a supersaturated sodium acetate solution or other solution, which is not limited here. At the same time, the interlayer cavity 1a may not be filled with a heating liquid as required, which is selected according to the specific needs.

[0037] Furthermore, the outer walls of the oil tank 1 and the liquid storage tank 4 are covered with cold-proof felt, and the oil tank 1 and the liquid storage tank 4 are protected from cold by the cold-proof felt. An oil inlet valve 11 is installed on the top of the oil tank 1, and the oil tank 1 is refueled later.

[0038] The oil tank 1 is provided with a controller 6 which is electrically connected to the explosion-proof temperature sensor 12, the servo motor 21, the cylinder 35 and the heating tube 5. The controller 6 can automatically control the opening and closing of the servo motor 21, the cylinder 35 and the heating tube 5.

[0039] The working principle of the box-type diesel generator oil tank with thermal insulation structure provided by the utility model is as follows:

[0040] Under normal circumstances, the cylinder 35 is in a closed state. At this time, the liquid drop hole 34a on the cylindrical valve core 34 is in a misaligned state with the threaded pipe 32 and the drain pipe 33, so the threaded pipe 32 and the drain pipe 33 are in a sealed state; when the explosion-proof temperature sensor 12 detects that the oil temperature is lower than the predetermined temperature, the cylinder 35 opens and pushes the cylindrical valve core 34 to slide into the mounting tube 31. At this time, the liquid drop hole 34a corresponds to the threaded pipe 32 and the drain pipe 33, so the pour point depressant in the liquid storage tank 4 falls into the oil tank 1, and adding an appropriate amount of pour point depressant to the oil can reduce its freezing point, thereby To prevent freezing, at the same time, the controller 6 drives the servo motor 21 to start, thereby driving the stirring rod 22 to stir the oil, thereby accelerating the mixing of the falling pour point depressant and the oil, greatly reducing the freezing point of the oil, and at the same time, the stirring rod 22 can also reduce the rate at which the oil becomes muddy or waxy due to low temperature. When the explosion-proof temperature sensor 12 detects that the oil temperature is lower than the preset temperature, the heating tube 5 starts and heats the heating liquid, and the heating liquid transfers the heated temperature from the oil tank 1 to the stored oil, thereby heating the oil and accelerating the rate of preheating and thawing of the oil.

[0041] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0042] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
