[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] See Figures 1 to 3 The pausing device for the plate and frame filter press disclosed in this utility model includes a mounting plate 1, a rotating component 2, a pull rope 3, a reset spring 4, a proximity sensor 5, and a limit block 6.

[0030] Specifically, the aforementioned mounting plate 1 serves as the mounting base for the other components in the suspension device, aiming to act as a connecting link between the components and the plate and frame filter press. Its function is simply to support the components. Of course, it is not limited to using the mounting plate 1 as a support base; mounting frames or mounting seats can also be used to support the components.

[0031] Furthermore, in this embodiment of the present invention, a plurality of mounting holes 101 are provided around the mounting plate 1, and the pausing device disclosed in this invention is installed onto the frame of the plate and frame filter press by means of the mounting holes 101.

[0032] Regarding the aforementioned rotating component 2, in this embodiment of the invention, one end of the rotating component 2 is connected by a pull rope 3. The purpose is to pull the rotating component 2 by pulling the pull rope 3, causing it to rotate on the mounting plate 1. The pull rope 3 can be pulled manually by an operator or driven by an external drive device. The pull rope 3 can be made of steel wire, plastic, or nylon. The key is to ensure that the pull rope 3 will not break during the pulling process and will not affect the pause of operations.

[0033] In addition, in this embodiment of the present invention, a rope hole 201 is provided on the aforementioned rotating part 2 for the aforementioned rope 3 to pass through.

[0034] In this embodiment of the invention, a return spring 4 is also provided, which enables the aforementioned rotating component 2 to rotate and then reset on the mounting plate 1. A fixing bolt is also provided between the rotating component 2 and the return spring 4. Specifically, one end of the return spring 4 is fixed to the aforementioned mounting plate 1, and more specifically, the mounting plate 1 has a return spring mounting hole 401 for mounting the return spring 4. The other end of the return spring 4 is connected to the rotating component 2 in a manner that enables the rotating component 2 to reset and rotate.

[0035] Regarding how the reset spring 4 can enable the rotating part 2 to reset and rotate, specifically, in this embodiment of the utility model, a spring extension hook 402 extends from the reset spring 4 along the length direction of the aforementioned rotating part 2, and a reset screw 202 is simultaneously inserted on the rotating part 2, and the reset screw 202 is simultaneously inserted in the aforementioned spring extension hook 402.

[0036] When the rotating component 2 is pulled on the mounting plate 1 by the pull rope 3, the reset screw 202 will move accordingly with the rotating component 2. When the pulling force of the pull rope 3 on the rotating component 2 is removed, combined with the rebound force of the reset spring 4 itself, the rotating component 2 will then reset and rotate.

[0037] Regarding the position of the rotating component 2 on the mounting plate 1 at which a signal to pause operation of the plate and frame filter press can be triggered, this embodiment of the invention includes a proximity sensor 5 on the mounting plate 1 to monitor and sense the position of the rotating component 2. The output of the proximity sensor 5 is connected to the control terminal of the plate and frame filter press. Specifically, when the rotating component 2 is pulled on the mounting plate 1 by the pull rope 3, as the rotating component 2 rotates into the sensing range of the proximity sensor 5, the proximity sensor 5 sends a signal to the control terminal of the plate and frame filter press. At this time, the control terminal of the plate and frame filter press issues a command to pause operation.

[0038] Meanwhile, to prevent the pull rope 3 from pulling the rotating component 2 excessively or to prevent the rotating component 2 from resetting excessively, in this embodiment of the invention, a limit block 6 is provided on the mounting plate 1 to prevent the rotating component 2 from rotating or resetting excessively. Specifically, the limit block 6 includes a first limit block 601 and a second limit block 602, which are disposed on both sides of the rotating component 2. The first limit block 601 is used to prevent the rotating component 2 from rotating excessively when pulled by the pull rope 3, and the second limit block 602 is used to prevent the rotating component 2 from resetting excessively. Of course, the use of the limit block 6 is not limited to the use of other limiting structures such as limit baffles.

[0039] Furthermore, in this embodiment of the invention, the end connecting the aforementioned rotating member 2 and the pull rope 3 is bent downwards to form a bent portion 203. The formation of the bent portion 203 creates a receiving space between the mounting plate 1 and the rotating member 2, which can accommodate the aforementioned return spring 4, resulting in a reasonable space arrangement. Moreover, when the rotating member 2 rotates on the mounting plate 1, its bent portion can receive the corresponding guiding force provided by the mounting plate 1, enabling the rotating member 2 to maintain stable movement and prevent deflection during rotation.

[0040] Furthermore, in practice, the aforementioned bent portion 203 cooperates with the aforementioned limiting block 6, with the bent portion 203 abutting against the limiting block 6 to limit the rotating component 2. In specific configuration, it is necessary to ensure that the lower end of the bent portion 203 is lower than the upper end surface of the aforementioned limiting block 6 in order to achieve the limiting effect.

[0041] In summary, the pausing device for a plate and frame filter press disclosed in this utility model integrates a rotating component, a return spring, a proximity sensor, and a limit block. When the plate and frame filter press needs to be stopped urgently, the rotating component is pulled by a pull rope. When the rotating component is pulled to the proximity sensor, the proximity sensor sends a pausing signal to the plate and frame filter press. The return spring is used to reset the rotating component, and the limit block is used to limit the rotation of the rotating component. The device has a simple structure, can immediately reset, and will not pull or reset excessively, and the signal response is sensitive.

[0042] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
