DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0020] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0021] Embodiment: A differential quick-opening fully automatic filter press, see attached Figure 1 and attached Figure 2 , including a frame, a thrust plate 3, a push plate 2, a filter plate 4, a hydraulic cylinder 9, a first transmission mechanism, a second transmission mechanism and an intermediate transmission mechanism; the thrust plate 3 is slidably connected to the frame; the push plate 2 is slidably connected to the frame; a plurality of filter plates 4 are provided and arranged between the push plate 2 and the thrust plate 3; the hydraulic cylinder 9 is used to push the push plate 2 to slide on the frame; the first transmission mechanism is transmission-connected to the push plate 2; the second transmission mechanism is connected to the thrust plate 3; the intermediate transmission mechanism is transmission-connected to the first transmission mechanism and the second transmission mechanism respectively to synchronously drive the thrust plate 3 to move when the push plate 2 moves. A chain is provided between two adjacent filter plates 4 to connect the two filter plates 4 together.

[0022] When the filter press is filtering, the hydraulic cylinder drives the push plate 2 to move toward the direction close to the thrust plate 3. During the movement of the push plate 2, the thrust plate 3 is driven to move toward the direction close to the push plate 2 by the first transmission mechanism, the second transmission mechanism and the third transmission mechanism, thereby accelerating the closing process of the filter plate 4. After the filtering is completed, when the filter plate 4 is opened, the hydraulic cylinder drives the push plate 2 to move away from the thrust plate 3. During the movement of the push plate 2, the thrust plate 3 is driven to move away from the push plate 2 by the first transmission mechanism, the second transmission mechanism and the third transmission mechanism, thereby accelerating the opening speed of the filter plate 4 and enabling all the filter plates 4 to be opened at once. By driving the push plate 2 and the thrust plate 3 to move together by the hydraulic cylinder, not only does it not need to add a new power source, but it can also shorten the stroke of the hydraulic cylinder and accelerate the closing and opening process.

[0023] Specifically, the first transmission mechanism includes a first transmission gear 51, a first transmission chain 52 and a first pull ear 53. The first transmission gear 51 is provided with two and is rotatably connected to the frame; the first transmission chain 52 surrounds the two first transmission gears 51 to form a closed loop; the first pull ear 53 is fixedly connected to the first transmission chain 52 and the push plate 2.

[0024] When the push plate 2 moves under the action of the hydraulic cylinder, it drives the first transmission chain 52 to rotate on the two first gears, and then drives the first transmission gear 51 to rotate through the meshing of the first transmission chain 52 and the first transmission gear 51.

[0025] Specifically, the second transmission mechanism includes a second transmission gear 61, a second transmission chain 62 and a second pull ear 63. The second transmission gear 61 is provided with two and is rotatably connected to the frame; the second transmission chain 62 surrounds the two second transmission gears 61 to form a closed loop; the second pull ear 63 is fixedly connected to the second transmission chain and the thrust plate 3.

[0026] When the second transmission gear 61 rotates, the second transmission chain 62 can be driven to rotate between the two second transmission gears 61 , thereby driving the thrust plate 3 to move through the second transmission chain 62 .

[0027] Specifically, the intermediate transmission mechanism includes an intermediate transmission gear 71 and an intermediate transmission chain 72. There are two intermediate transmission gears 71, and the two intermediate transmission gears 71 are respectively fixedly connected to one of the first transmission gears 51 and one of the second transmission gears 61; the intermediate transmission chain 72 surrounds the two intermediate transmission gears 71 to form a closed loop.

[0028] When the first transmission gear 51 rotates under the action of the first transmission chain 52, it will drive the intermediate transmission gear 71 connected to the first transmission gear 51 to rotate. The intermediate transmission gear 71 connected to the first transmission gear 51 drives the intermediate transmission gear 71 connected to the second transmission gear 61 to rotate through the intermediate transmission chain 72, thereby synchronously driving the second transmission gear 61 to rotate, and then the thrust plate 3 can be driven to slide through the second transmission chain 62.

[0029] Specifically, the present embodiment further comprises a locking mechanism 8 , which is disposed on the frame and is used to lock the position of the thrust plate 3 when the thrust plate 3 and the push plate 2 press the plurality of filter plates 4 .

[0030] The locking mechanism 8 is configured as a locking rod, which is arranged on the thrust plate 3 or the frame. When the locking rod is arranged on the thrust plate 3, a locking hole corresponding to the locking rod is arranged on the frame corresponding to the position where the thrust plate 3 presses the multiple filter plates 4; when the locking rod is arranged on the frame, the locking rod is arranged on the frame corresponding to the position where the thrust plate 3 presses the multiple filter plates 4, and a locking hole is arranged on the thrust plate 3. Both methods can lock the thrust plate 3 by inserting the locking rod into the locking hole when the thrust plate 3 presses the multiple filter plates 4.

[0031] Specifically, the frame includes a supporting end 12, a hydraulic support and a side frame 13. The supporting end 12 is provided with a thrust plate 3 away from the push plate 2; the hydraulic support is provided on the side of the push plate 2 away from the thrust plate 3; two side frames 13 are provided and are respectively arranged on both sides of the supporting end 12, and the two ends of the side frame 13 are respectively fixedly connected to the supporting end 12 and the hydraulic support.

[0032] Specifically, the two first transmission gears 51 of the first transmission mechanism are respectively arranged on the side of the push plate 2 close to the thrust plate 3 and the side away from the thrust plate 3 ; the arrangement direction of the two first transmission gears is arranged along the sliding direction of the push plate 2 .

[0033] The two second transmission gears 61 of the second transmission mechanism are respectively arranged on the support end 12 and the hydraulic support.

[0034] Specifically, in the intermediate transmission mechanism, the number of teeth of the intermediate transmission gear 71 connected to the first transmission gear 51 is greater than the number of teeth of the intermediate transmission gear connected to the second transmission gear 61. By the difference in the number of teeth of the intermediate transmission gear 71 in the intermediate transmission mechanism, the push plate 2 and the thrust plate 3 achieve differential movement.

[0035] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
