Description

Technical Field

[0001] The utility model relates to the technical field of combustion engine equipment, in particular to a plate-shaped filter element installation mechanism for combustion engines. Background Art

[0002] A gas turbine is an internal combustion power machine that uses a continuously flowing gas as a working fluid to drive the impeller to rotate at high speed, converting the energy of the fuel into useful work. The gas turbine has very high requirements for air cleanliness. The air intake system is the only line of defense for external air to enter the gas turbine. It provides the gas turbine with clean air that meets the requirements through filtering, dehumidification and other measures to ensure the normal operation of the gas turbine. After the air passes through the dewatering and demisting device of the air intake system, it will enter the filter chamber and pass through the plate-shaped air filter with a filtration grade of G4 for primary filtration. The plate-shaped air filter mainly filters dust, sand or oil and water in the air to ensure that clean air enters the subsequent filtration device and gas turbine.

[0003] In the prior art, the plate filter element of the gas turbine needs to be cleaned and maintained regularly after long-term operation. Dust and gravel will accumulate on the surface of the common plate filter element structure after long-term operation, which causes certain inconveniences when disassembling the filter plate, thereby reducing the maintenance efficiency of the filter plate.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2In this embodiment, a plate-shaped filter element installation mechanism for a fuel engine includes a chassis 1, at least two clamping plates 2, at least two filter plates 3 and a locking assembly 4; at least two clamping plates 2 are vertically installed on the inner bottom wall of the chassis 1, at least two filter plates 3 are respectively slidably connected to the inside of the at least two clamping plates 2, and at least two square openings are opened on the inner top wall of the chassis 1 to allow the at least two filter plates 3 to move up and down respectively. The locking assembly 4 is installed on the chassis 1 to lock the at least two filter plates 3.

[0023] During the actual setting, the two filter plates 3 are inserted from the inside of the square opening inside the chassis 1, and the bottom ends of the filter plates 3 extend into the card plate 2. At the same time, the two card plates 2 are locked by the locking assembly 4, so that the card plates 2 are fixed inside the card plate 2.

[0024] It should be noted that the shape of the clamping plate 2 is U-shaped, and a sliding groove for the filter plate 3 to be embedded is provided on the inner side of the clamping plate 2 .

[0025] See also Figure 3 In order to facilitate the fixing of the card plate 2, the locking assembly 4 in this embodiment includes at least two side plates 401, and at least the two side plates 401 are respectively installed on the left and right sides of the chassis 1. A screw 402 is rotatably connected between the opposite sides of at least the two side plates 401 through a bearing, and the outer surface of the screw 402 is threadedly connected to two driving blocks 403. The bottom of the two driving blocks 403 is installed with a locking plate 404, and the locking plate 404 is slidably connected to the chassis 1.

[0026] During actual use, the two filter plates 3 are respectively inserted into the interior of the two card plates 2, and the screw 402 is rotated to drive the two driving blocks 403 on the outside thereof to move toward each other. At the same time, the two driving blocks 403 respectively drive the two locking plates 404 to move toward each other, so that the two locking plates 404 are respectively embedded in the grooves on both sides of the filter plate 3, thereby fixing the filter plate 3 in the card plate 2 and making the filter plate 3 located inside the chassis 1.

[0027] It should be noted that in order to enable the locking plates 404 to be effectively embedded in the interior of the filter plate 3, the opposite sides of the two locking plates 404 are arranged in an inclined shape, and corresponding to the two locking plates 404, grooves for the locking plates 404 to be embedded are opened on both sides of the filter plate 3; the two grooves are located on the same horizontal line.

[0028] In actual use, the two locking plates 404 move toward each other and are respectively embedded in the grooves on both sides of the filter plate 3, so as to fix the filter plate 3.

[0029] In addition, when the filter plate 3 needs to be disassembled, the two driving blocks 403 can be driven to move backwards by rotating the screw rod 402 in the opposite direction, so that the two locking plates 404 are respectively moved out from the inside of the two filter plates 3. At this time, the filter plate 3 can be moved out from the inside of the chassis 1.

[0030] Furthermore, in order to ensure that the two driving blocks 403 can move towards or away from each other when the screw 402 rotates, two thread grooves are opened on the outer surface of the screw 402, and the thread directions of the two thread grooves are opposite, and the two driving blocks 403 are symmetrically distributed on the left and right sides of the outer surface of the screw 402.

[0031] Furthermore, in order to facilitate driving the screw rod 402 to rotate, one of the side panels 401 is internally rotatably connected to a knob 405 having one end drivingly connected to the screw rod 402 . In actual use, the screw rod 402 can be driven to rotate by rotating the knob 405 .

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
