Description

Technical Field

[0001] The utility model belongs to the technical field of diesel engine filters, and particularly relates to an integrated fuel and waste oil collector for medium-speed marine diesel engines. Background Art

[0002] A medium-speed marine diesel engine is an engine used to be installed on a ship's hull to provide power for the hull. During the operation of a medium-speed marine diesel engine, in order to maintain the cleanliness of the engine cylinder block, a filter needs to be installed on the diesel engine. The function of the filter is to pre-filter the diesel entering the engine cylinder block and remove impurities.

[0003] However, during the operation, since the filters of existing diesel engines are installed in a naked manner, such as being fixedly installed on the diesel engine by simple structures such as bolts and mounting brackets. Along with the high-intensity vibration of the diesel engine, the filter is extremely prone to looseness, and the sealing structure of the filter is easily damaged under high-intensity vibration, resulting in a decrease in sealing performance.

[0004] Therefore, during use, the filter is prone to oil leakage. And when there is no oil residue blockage of solid debris in the diesel engine, it further causes the filter to be prone to oil leakage. Specifically, after the high-pressure oil pump enters the filter, its sealing structure is loosened due to long-term vibration, and it is more prone to oil leakage under blockage.

[0005] Therefore, the leaked diesel is not only easy to spill and pollute the engine and electrical compartment, but also because there are many and complex electrical equipment, pipelines, and pipeline equipment installed at the position where the diesel engine is installed, it is more difficult to clean up the leaked and polluted diesel. Moreover, it increases the risk of fire in the engine and electrical compartment.

[0006] Therefore, during the actual operation process, first, it is necessary to strengthen the installation stability of the filter to reduce the defect that its sealing structure is easily damaged and leaks oil due to the vibration of the diesel engine during operation. Secondly, it is necessary to handle the leaked oil in case of oil leakage to avoid polluting the engine and electrical compartment. Content of the Utility Model

[0046] Embodiment 1

[0047] Such as Figure 1-6As shown in the figure, an integrated fuel oil and sludge collector for marine medium-speed diesel engines includes a mounting plate 1 detachably and fixedly installed on the diesel engine (specifically, a number of countersunk mounting screws 11 for installing on the diesel engine are threadedly connected to the mounting plate 1), and a filter installation mechanism is assembled and connected to the mounting plate 1. The filter 3 is installed on the mounting plate 1 through the filter installation mechanism. Specifically, by means of the mounting plate 1, it is avoided that the filter 3 is installed in a way that directly contacts the diesel engine, and through the blocking effect of the mounting plate 1, the amplitude of the high-intensity vibration of the filter 3 caused by the working vibration of the diesel engine is appropriately reduced. The filter 3 is protected.

[0048] According to the conventional method of the prior art, the back surface of the mounting plate 1 is fastened to the housing of the filter 3 through a countersunk screw (not shown in the figure), and the filter 3 is preliminarily fixed through the screw.

[0049] At the same time, in order to increase the fixing stability of the filter 3, the above-mentioned filter installation mechanism includes a mounting frame 41, and the shape of the mounting frame 41 is: the mounting frame 41 includes cross-arm parts arranged at intervals up and down, and the mounting frame 41 is elastically and fixedly installed on the mounting plate 1.

[0050] Specifically, a connecting column 43 is fixedly connected between the cross-arm parts, and the connecting column 43 is installed on the mounting plate 1 through a spring sliding structure. The spring sliding structure includes slide screws 431 arranged at intervals up and down and slidably connected to the connecting column 43, and the inner ends of the slide screws 431 are fixedly connected to the mounting plate 1; a telescopic spring 432 is sleeved on the slide screws 431, and both ends of the telescopic spring 432 are fixedly connected to the side walls facing each other with the mounting plate 1; the outer ends of the slide screws 431 are threadedly connected with nuts 433.

[0051] During the working process, when the nut 433 is screwed inward, at this time, the mounting frame 41 moves towards the mounting plate 1, and the telescopic spring 432 is in a compressed state.

[0052] In order to further lock the filter, both ends of the above-mentioned mounting frame 41 are respectively hinged with clamps 42 that are clamped on the outside of the filter 3 (the inner ends of the clamps 42 are respectively hinged to the cross-arm parts through pins at the top and bottom), and the free ends of the clamps 42 are locked and fixed to the mounting plate 1 through a locking structure.

[0053] The locking structure includes lock posts 421 elastically installed at the top and bottom positions of the outer ends of the clamps 42 respectively; a pair of locking seats 43 locked between the lock posts 421 are fixedly connected to the mounting plate 1; locking holes are respectively opened on the locking seats 43 (in the same way as the existing method, locking post grooves are respectively opened at the top and bottom of the outer ends of the clamps 42, and inner springs are fixedly connected between the lock posts 421 and the lock post grooves, and pressing the lock posts 421 realizes the elastic lifting of the lock posts 421).

[0054] Similar to the existing method, a curved portion is integrally formed at the outer end of the above-mentioned locking post 421.

After the clamp 42 is tightened, the locking post 421 is locked into the locking hole. When unlocking, press the locking post 421 to disengage the locking post 421 from the locking hole.

[0056] Then, turn the nut on the sliding screw rod 431 outwards. With the elastic force of the telescopic spring 432, at this time, the mounting bracket 41 disengages.

[0057] The filter 3 is locked in the above-mentioned manner. During the working process, under the tightening of the clamp 42, the filter 3 is kept stable under the high-intensity vibration of the diesel engine, thereby avoiding the occurrence of oil leakage and pollution caused by the loosening of the sealing structure of the filter 3.

Then, during the maintenance process by the operator, the sewage oil pipeline at the bottom of the filter 3 is opened (the oil inlet and outlet pipeline structures 31 of the filter 3 are located at the upper end of the filter 3). At this time, the dirty oil enters the sewage pipe, and under the action of the sewage pipe 44, the dirty oil is prevented from splashing. The dirty oil is discharged from the strip-shaped oil discharge holes 441 into the oil receiving shell 2.

[0062] An oil discharge hole is opened on the above-mentioned oil receiving shell 2, and a drain pipe 21 is connected to the bottom of the oil discharge hole, and a valve is installed on the drain pipe 21. Finally, the dirty oil is discharged from the drain pipe 21.

[0065] Specifically, having the same structure as the existing filter, the filter element 5 includes a filter screen base arranged at intervals up and down (the filter screen base is an annular base, and the filter screen base at the bottom is fastened to the edge of the oil drain hole by bolts for convenient disassembly and replacement), and a cylindrical filter screen (the cylindrical filter screen is a metal mesh) is fixedly connected between the filter screen bases. The waste oil enters the cylindrical filter screen cavity along the cylindrical filter screen and then enters the oil drain pipe through the oil drain hole for downward discharge.
