Technical Field

[0001] The present invention relates to the technical field of diesel generators, and particularly to a diesel generator with a supply filtering device. Background Art

[0002] A diesel generator set is a power mechanical system composed of a diesel engine, a generator, a control system, and auxiliary devices such as a fuel tank, a battery, and a protection device. Its core function is to convert the chemical energy of diesel into electrical energy. Depending on the application scenario, it may also include components such as a muffler, a coupling, and a common base.

[0003] Traditional filtering structures are mostly single-layer filter screens or single filter materials, which are difficult to handle impurities of different particle sizes in diesel, resulting in incomplete filtration, easy to cause injector blockage or a decrease in combustion efficiency, and the filtering device needs to be frequently shut down and disassembled for cleaning or filter element replacement, significantly increasing the maintenance time and labor cost, especially having a serious impact on scenarios that require continuous power supply. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a diesel generator with a supply filtering device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A diesel generator with a supply filtering device includes a diesel power generation module. On one side of the diesel power generation module, there is an installation seat. An oil pump is arranged on the installation seat for delivering diesel to the diesel power generation module. The oil pump pumps out diesel from the fuel tank. Between the connecting pipe of the oil pump and the fuel tank, a flow splitting module is symmetrically arranged, and diesel filtering pipes are symmetrically installed between the flow splitting modules.

[0007] The flow splitting module includes a flow splitting mechanism and a flow splitting ball valve. The flow splitting mechanism is used to split the diesel flowing in the flow splitting ball valve. The flow splitting mechanism is installed on both sides of the installation frame located on the installation seat, and the flow splitting ball valve is arranged between the oil pump and the diesel filtering pipe, and between the fuel tank and the diesel filtering pipe.

[0008] One side of the diesel filtering pipe connected to the flow splitting module is installed on the filtering pipe connecting frame of the driving mechanism. The driving mechanism is arranged on the top of the installation frame. The driving mechanism is used to drive the installed diesel filtering pipe to displace horizontally. A liquid collecting mechanism is arranged below the driving mechanism on the installation frame. The liquid collecting mechanism is used to collect the diesel dripping from the diesel filtering pipe. A cleaning module is arranged on the installation frame for cleaning the diesel filtering pipe installed on the driving mechanism.

[0009] In addition, a preferred structure is that a rotating cavity is formed inside the flow splitting ball valve. A flow splitting mechanism is arranged above the shell of the rotating cavity of the flow splitting ball valve. Auxiliary transmission pipes are symmetrically arranged on both sides of the flow splitting ball valve and are used to connect diesel filter pipes. A main transmission pipe is arranged on one side of the auxiliary transmission pipe.

[0010] In addition, a preferred structure is that the flow splitting mechanism includes a motor. The motor is arranged on the top of the shell of the flow splitting ball valve. The output end at the bottom of the motor is equipped with a rotating shaft, and the bottom of the rotating shaft extends and is connected to a flow splitting ball arranged inside the rotating cavity;

[0011] The flow splitting ball is used to block the auxiliary transmission pipe, and a flow groove is formed on the flow splitting ball.

[0012] In addition, a preferred structure is that the driving mechanism includes a servo electric cylinder. The servo electric cylinder is horizontally installed on the top of the mounting frame. A piston rod is assembled at one end of the servo electric cylinder away from the diesel power generation module, and a filter pipe connecting frame is assembled and connected to the end of the piston rod;

[0013] Sliders are symmetrically arranged on the filter pipe connecting frame and are slidably matched with slide rails arranged at the bottom of the mounting frame.

[0014] In addition, a preferred structure is that the filter pipe connecting frame includes a main frame body. The top of the main frame body is assembled and connected to the end of the piston rod. First clamping rings are symmetrically arranged on one side surface of the main frame body away from the diesel power generation module. Second clamping rings are symmetrically installed on one side of the first clamping rings, and a diesel filter pipe is installed between the first clamping rings and the second clamping rings.

[0015] In addition, a preferred structure is that limiting blocks are symmetrically arranged up and down at both ends of the outer wall of the diesel filter pipe and are used for positioning the first clamping rings and the second clamping rings. A cavity for filtering diesel is formed inside the diesel filter pipe, and a screen, filter sand, and hollow ceramic microspheres are arranged in sequence in the internal cavity of the diesel filter pipe.

[0016] In addition, a preferred structure is that the cleaning module includes a pulse pump. The pulse pump is installed on the mounting seat, and the output end of the pulse pump is arranged on one side of the liquid collecting mechanism.

[0017] In addition, a preferred structure is that the liquid collecting mechanism includes a liquid collecting frame. The liquid collecting frame is located below the diesel filter pipe installed on the driving mechanism. An installation socket is arranged at the bottom of the liquid collecting frame, and a waste oil collecting box is horizontally inserted at the installation socket. An impurity cleaning baffle is arranged on the other side of the liquid collecting frame away from the output end of the pulse pump.

[0018] The beneficial effects of the present invention are as follows: By sequentially arranging a screen, filter sand, and hollow ceramic microspheres inside the diesel filter pipe, the present invention forms a gradient filtration system, which can intercept large particulate impurities, colloids, and tiny suspended matters step by step, significantly improve the fuel cleanliness, extend the service life of the generator set, and the driving mechanism and the cleaning module work together. The diesel filter pipe is driven by a servo electric cylinder to move horizontally to the output end of the pulse pump, and the filter material is reversely flushed by high-pressure air flow to achieve cleaning without shutting down the machine, reduce manual intervention and ensure power supply continuity. The shunt module controls the rotation of the shunt ball through a motor to quickly block or open the secondary transmission pipe, realizing seamless switching of the double filtration channels. The standby diesel filter pipe can take over the work during the cleaning of the main channel to ensure zero interruption of fuel supply. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] Refer to Figures 1-10 , a diesel generator with a supply filtering device, including a diesel power generation module 01. A mounting seat 1 is arranged on one side of the diesel power generation module 01. An oil pump 02 for delivering diesel to the diesel power generation module 01 is arranged on the mounting seat 1. The oil pump 02 pumps out diesel from the fuel tank 06. Shunt modules 03 are symmetrically arranged between the connecting pipes of the oil pump 02 and the fuel tank 06. Diesel filter pipes 05 are symmetrically installed between the shunt modules 03. The shunt module 03 includes a shunt mechanism 4 and a shunt ball valve 3. The shunt mechanism 4 is used to shunt the diesel flowing in the shunt ball valve 3. The shunt mechanism 4 is installed on both sides of the mounting bracket 2 located on the mounting seat 1. The shunt ball valve 3 is arranged between the oil pump 02 and the diesel filter pipe 05, and between the fuel tank 06 and the diesel filter pipe 05. The fuel tank 06 is used to store diesel.

[0032] Among them, one side of the diesel filter pipe 05 connected to the shunt module 03 is installed on the filter pipe connection frame 7 of the driving mechanism 5. The driving mechanism 5 is arranged on the top of the mounting bracket 2. The driving mechanism 5 is used to drive the installed diesel filter pipe 05 to move horizontally. A liquid collection mechanism 6 is arranged below the driving mechanism 5 on the mounting bracket 2. The liquid collection mechanism 6 is used to collect the diesel dripping from the diesel filter pipe 05. A cleaning module 04 for cleaning the diesel filter pipe 05 installed on the driving mechanism 5 is arranged on the mounting bracket 2. The driving mechanism 5 can effectively drive the diesel filter pipe 05 for automatic cleaning.

[0033] In addition, a rotating cavity 31 is provided inside the flow-dividing ball valve 3. A flow-dividing mechanism 4 is arranged above the housing of the flow-dividing ball valve 3 located in the rotating cavity 31. Auxiliary transmission pipes 33 are symmetrically arranged on both sides of the flow-dividing ball valve 3. The auxiliary transmission pipes 33 are used to connect the diesel filter pipe 05. A main transmission pipe 32 is arranged on one side of the auxiliary transmission pipe 33. The flow-dividing mechanism 4 includes a motor 41. The motor 41 is arranged on the top of the housing of the flow-dividing ball valve 3. The output end of the bottom of the motor 41 is equipped with a rotating shaft 42. The bottom of the rotating shaft 42 extends and is connected to a flow-dividing ball 43 arranged in the rotating cavity 31. The flow-dividing ball 43 is used to block the auxiliary transmission pipe 33. A flow groove 431 is provided on the flow-dividing ball 43. The flow-dividing ball 43 is used to block one side of the auxiliary transmission pipe 33.

[0034] Moreover, the driving mechanism 5 includes a servo electric cylinder 51. The servo electric cylinder 51 is horizontally installed on the top of the mounting frame 2. A piston rod 52 is assembled at the end of the side of the servo electric cylinder 51 away from the diesel power generation module 01. The end of the piston rod 52 is assembled and connected to a filter pipe connecting frame 7. Sliders 53 are symmetrically arranged on the filter pipe connecting frame 7. The sliders 53 are slidably engaged with a slide rail 21 arranged at the bottom of the mounting frame 2. The piston rod 52 is used to drive the diesel filter pipe 05 to move, so as to facilitate cleaning by the pulse pump 041.

[0035] In addition, the filter pipe connecting frame 7 includes a main frame body 71. The top of the main frame body 71 is assembled and connected to the end of the piston rod 52. First clamping rings 72 are symmetrically arranged on the surface of the side of the main frame body 71 away from the diesel power generation module 01. Second clamping rings 73 are symmetrically installed on one side of the first clamping rings 72. The diesel filter pipe 05 is installed between the first clamping rings 72 and the second clamping rings 73. Limiting blocks 051 are symmetrically arranged up and down at both ends of the outer wall of the diesel filter pipe 05. The limiting blocks 051 are used for positioning the first clamping rings 72 and the second clamping rings 73. A cavity for filtering diesel is provided inside the diesel filter pipe 05. A screen 052, filter sand 053, and hollow ceramic microspheres 054 are arranged in sequence in the internal cavity of the diesel filter pipe 05. This multi-stage filtering of the screen 052, filter sand 053, and hollow ceramic microspheres 054 can effectively filter diesel.

[0036] Meanwhile, the cleaning module 04 includes a pulse pump 041. The pulse pump 041 is installed on the mounting seat 1. The output end of the pulse pump 041 is arranged on one side of the liquid collecting mechanism 6. The liquid collecting mechanism 6 includes a liquid collecting frame 61. The liquid collecting frame 61 is located below the diesel filter pipe 05 installed on the driving mechanism 5. An installation socket 62 is provided at the bottom of the liquid collecting frame 61. An oil waste collecting box 63 is horizontally inserted at the installation socket 62. An impurity cleaning baffle 64 is arranged on the other side of the liquid collecting frame 61 away from the output end of the pulse pump 041. The impurity cleaning baffle 64 is used to collect impurities blown out of the diesel filter pipe 05 by the pulse pump 041.

[0037] In this embodiment, when the diesel power generation module 01 is operating, diesel is pumped out of the fuel tank 06 by the fuel pump 02 and then transported to the diesel power generation module 01 for use. During this process, the diesel will pass through the secondary transfer pipe 33 connected to the fuel tank 06, then enter the rotating gun 31, and then enter the diesel filter pipe 05 through the main transfer pipe 32 and be transported to the diverter valve 3 on the other side. During this process, the diesel passes through the screen 052, filter sand 053, and hollow ceramic microspheres 054, which can effectively filter the impurities in the diesel, ensuring that the diesel input into the diesel power generation module 01 is purer and free of impurities. The filtered diesel then enters the diverter valve 3 connected to the fuel pump 02 and is input into the diesel power generation module 01 through the fuel pump 02.

[0038] After the diesel filter pipe 05 has been used for a long time, it is necessary to clean its interior to ensure its filtration efficiency. At this time, the fixing components on the flanges on both sides of the diesel filter pipe 05 installed on the filter pipe connecting frame 7 are unscrewed, and the drive mechanism 5 is started. The servo cylinder 51 pushes the piston rod 52 to move the diesel filter pipe 05 to one side of the output end of the pulse pump 041 blowing. At this time, the pulse pump 041 blows out high-pressure air, so that some of the impurities attached to the screen 052, filter sand 053, and hollow ceramic microspheres 054 are blown out of the diesel filter pipe 05 along with the diesel, and these impurities are blown onto the impurity cleaning baffle 64 to prevent them from splashing to the outside. The impurities and waste oil are collected by the waste oil collection box 63. After the cleaning is completed, the drive mechanism 5 is reset, and the diesel filter pipe 05 is reinstalled to ensure its connectivity.

[0039] When cleaning the diesel filter pipe 05 installed on the filter pipe connecting frame 7, in order to ensure that the operation of the diesel power generation module 01 is not suspended, the other spare diesel filter pipe 05 can be used for filtration. First, the flow is divided through the flow dividing mechanism 4. The motor 41 drives the rotating shaft 42 to rotate, and the diverter ball 43 rotates in the rotating cavity 31, thus blocking the secondary transfer pipe 33 connected to the diesel filter pipe 05 installed on the filter pipe connecting frame 7 and enabling the secondary transfer pipe 33 on the other side, thereby realizing the switching of the diesel pipeline and using the spare diesel filter pipe 05 for filtration. Since the spare diesel filter pipe 05 has been used for a short time, it does not need to be cleaned frequently. After each stop of the diesel power generation module 01, it can be disassembled and cleaned.

[0040] In the present invention, a gradient filtration system is formed by sequentially arranging a screen 052, filtration sand 053 and hollow ceramic microspheres 054 inside a diesel filtration pipe 05, which can intercept large particle impurities, gum and tiny suspended substances step by step, significantly improve the fuel cleanliness, extend the service life of the generator set, and the driving mechanism 5 and the cleaning module 04 work together. The diesel filtration pipe 05 is driven by a servo electric cylinder 51 to move horizontally to the output end of a pulse pump 041, and the filter media is reversely flushed by high-pressure air flow to achieve cleaning without shutdown, reduce manual intervention and ensure power supply continuity. The flow splitting module 03 controls the rotation of a flow splitting ball 43 through a motor 41 to quickly block or open a secondary transmission pipe 33, realizing seamless switching of double filtration channels. The standby diesel filtration pipe 05 can take over the work during the cleaning of the main channel to ensure zero interruption of fuel supply.

[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
