[0062] By rotating the hand-cranked pusher 3, the multiple plate frames 2 and the pressure plates on both sides are pressed against each other to form a closed structure. After the filtration is completed, the hand-cranked pusher 3 is rotated in the opposite direction to separate the multiple plate frames 2 and the pressure plates on both sides, and the filtered waste residue is discharged;

[0063] In this embodiment, the number of plate frames 2 is seventeen;

[0064] The top surface of the plate frame 2 is designed to be open, and filter plates 8 are longitudinally inserted on both the left and right sides of the inner cavity of the plate frame 2;

[0065] The outer wall of the plate frame 2 is located between the filter plates 8 on both sides and the lower end is fixedly connected with an oil outlet pipe, which is used to discharge the oil filtered by the filter plates 8 on both sides;

[0068] The lower ends of the vertical rods 54 are respectively threadedly connected to the top surfaces of the corresponding filter plates 8, and the two are screwed together for easy installation and removal;

[0069] When it is necessary to replace the filter plate 8, the filter plate connecting handle rod 5 is lifted up to disengage from the clamping of the round rod elastic clamping parts 4 on both sides, thereby driving each filter plate 8 to rise and disengage from the upper end opening of the plate frame 2 for disassembly, so that the filter plate 8 can be disassembled separately from the plate frame 2, unscrewed and replaced with a new filter plate 8; reverse the operation, insert each new filter plate 8 back into the corresponding plate frame 2, and insert the filter plate connecting handle rod 5 back and snap it into the round rod elastic clamping parts 4 on both sides, so that multiple filter plates 8 can be disassembled and replaced at the same time, reducing time consumption and improving work efficiency.

[0070] In some embodiments, in order to manually lift and lower the filter plates 8 to facilitate simultaneous replacement of multiple filter plates 8, the filter plate connecting handle 5 includes:

[0071] The crossbar 51 has support rods 52 fixed vertically on both sides of the middle of its upper surface, and handle rods 53 fixed on the upper ends of the support rods 52 on both sides;

The grasping groove 55 facilitates grasping the handle rod 53, and the anti-slip cover 56 plays an anti-slip role.

[0074] In some embodiments, in order to elastically clamp and limit the two ends of the inserted filter plate connecting handle rod 5 and facilitate the removal of the filter plate connecting handle rod 5 by applying an upward force when necessary, the round rod elastic clamping member 4 includes:

[0075] an elastic metal semi-cylinder 41 with its opening facing upward;

[0076] Notches 42 are evenly formed along the length of the front and rear edges of the elastic metal semi-cylinder 41;

[0077] The height of the elastic metal semi-cylinder 41 is greater than the length of its radius. The elastic metal semi-cylinder 41 is made of spring steel. The uniform opening of the upper edge notches 42 increases the elastic deformation capacity of the front and rear edges of the elastic metal semi-cylinder 41. When the filter plate connecting handle rod 5 is inserted or withdrawn, it can be deformed and opened. After the filter plate connecting handle rod 5 is inserted, the elastic metal semi-cylinder 41 resets to clamp it.

[0078] In some embodiments, in order to manually control the compression of the plurality of plate frames 2 and the pressure plates on both sides to form a closed structure for filtering the oil, the hand-cranked pusher 3 includes:

[0079] A screw 32 is screwed to the outer wall of the mounting bracket 1 away from the plate frame 2;

[0080] The screw rod 32 is located on one end of the outer side of the mounting bracket 1 and is fixedly mounted with a circular plate 31. The upper end of the outer wall of the circular plate 31 is fixedly connected with a hand crank 34 to facilitate manual rotation of the screw rod 32.

[0081] The screw rod 32 is located inside the mounting bracket 1 and one end thereof is fixedly sleeved with a bearing 33 , and the bearing 33 is fixedly connected to the outer wall of the adjacent pressure plate through a connecting flange. The rotation of the screw rod 32 pushes and pulls the adjacent pressure plate to slide horizontally on the mounting bracket 1 .

[0082] In some embodiments, in order to simultaneously supply the oil to be filtered between the two filter plates 8 in each plate frame 2 from the front and rear sides, so that the replacement cycle of multiple filter plates 8 is the same and they can be replaced at the same time, the mounting bracket 1 is equipped with a sliding oil inlet pipeline 6 on the side close to the plate frame 2, which includes:

[0083] There are two slide grooves 63, which are respectively opened transversely at the front and rear edges of the upper end of the inner wall of the mounting bracket 1 close to the plate frame 2;

[0085] The inner end of the oil inlet pipe 65 is integrally formed with one end of the cross pipe 61, and the other end of the cross pipe 61 is sealed;

[0086] The bottom surface of the horizontal pipe 61 is fixedly connected to the filter plates 8 on both sides of each plate frame 2 with a drainage pipe 62;

[0087] A strip-shaped horizontal plate 66 is fixedly mounted on the lower end of the outer wall of the sliding groove 63 , and a sliding groove matching the sliding block 64 is formed along the length direction of the strip-shaped horizontal plate 66 .

[0088] When the filter plate 8 needs to be replaced, the oil inlet pipe 65, the transverse pipe 61 and the drain pipe 62 are pulled outwards. The slider 64 on the outer wall of the oil pipe 65 slides outwards on the slide groove 63 and the strip-shaped transverse plate 66, so that the transverse pipe 61 and the drain pipe 62 are separated from the top of the filter plate 8 and will not hinder the lifting and lowering of the filter plate 8.

[0089] After the filter plate 8 is replaced, the sliding oil inlet pipeline 6 is reset, and the oil to be filtered is supplied through the oil inlet pipe 65. The oil enters between the filter plates 8 on both sides of each plate frame 2 along the cross pipe 61 and the drain pipe 62, realizing simultaneous oil supply.

[0090] In some embodiments, in order to increase the friction force when the round rod elastic clamp 4 clamps and limits the filter plate connection handle rod 5, rubber pads 7 are laterally glued and fixed to the front and rear side walls of the cross bar 51, and the outer wall of the rubber pad 7 fits with the inner wall of the round rod elastic clamp 4.

[0091] In some embodiments, in order to stably support the device and provide a device mounting position, the mounting bracket 1 includes:

[0092] There are two side panels 11 arranged parallel to each other.

[0093] The front and rear sides of the inner sides of the side panels 11 are fixedly mounted with transverse panels 12;

[0094] The plate frame 2 and the front and rear side walls of the pressure plate are fixedly connected to the corresponding horizontal plate 12 on the same side with an L-shaped plate, and the L-shaped plate is slidably sleeved on the upper end of the horizontal plate 12 on the same side;

[0095] The bottom surface of the side panel 11 is evenly and fixedly equipped with supporting legs 13 .

[0096] In some embodiments, in order to assist in limiting the position of the filter plate 8 inserted into the plate frame 2 , an auxiliary clamping structure 9 is installed between the lower ends of the front and rear side walls of the filter plate 8 and the inner wall of the plate frame 2 .

[0097] In some embodiments, in order to assist in limiting the position of the filter plate 8 inserted into the plate frame 2 and improve the stability of the positioning of the filter plate 8 in the plate frame 2, the auxiliary clamping structure 9 includes:

[0098] The clamping grooves 92 are symmetrically arranged at the lower ends of the front and rear side walls of the filter plate 8;

[0099] The inner wall of the plate frame 2 is provided with a mounting groove 91 corresponding to the clamping groove 92 on the same side;

[0100] One end of a spring 93 is fixedly connected transversely in the mounting groove 91, and the other end of the spring 93 is fixedly connected to a clamping block 94;

[0101] The card block 94 is clamped in the clamping groove 92 on the same side, and the edge of the inner side end of the card block 94 is designed with an arc chamfer; the spring 93 pushes the card block 94 to clamp in the clamping groove 92, realizing auxiliary limiting between the filter plate 8 and the plate frame 2. If disassembly is required, the filter plate 8 is lifted up to overcome the elasticity of the spring 93, and the arc chamfer of the card block 94 contacts the inner wall edge of the clamping groove 92. The card block 94 is squeezed by the force to squeeze the spring 93 to contract, and the card block 94 retracts into the installation groove 91, and the filter plate 8 can be smoothly pulled out of the plate frame 2.

[0102] Working principle:

[0103] By rotating the hand-cranked pusher 3, the multiple plate frames 2 and the pressure plates on both sides are pressed against each other to form a closed structure. The oil to be filtered is supplied between the filter plates 8 on both sides of the plate frame 2. The oil outlet pipe is used to discharge the oil filtered by the filter plates 8 on both sides. After the filtration is completed, the hand-cranked pusher 3 is rotated in the opposite direction to separate the multiple plate frames 2 and the pressure plates on both sides, and the filtered waste residue is discharged;

[0104] When it is necessary to replace the filter plate 8, the filter plate connecting handle rod 5 is lifted up to disengage from the clamping of the round rod elastic clamping parts 4 on both sides, thereby driving each filter plate 8 to rise and disengage from the upper end opening of the plate frame 2 for disassembly, so that the filter plate 8 can be disassembled separately from the plate frame 2, unscrewed and replaced with a new filter plate 8; reverse the operation, insert each new filter plate 8 back into the corresponding plate frame 2, and insert the filter plate connecting handle rod 5 back and snap it into the round rod elastic clamping parts 4 on both sides, so that multiple filter plates 8 can be disassembled and replaced at the same time, reducing time consumption and improving work efficiency.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
