[0024] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present utility model is not limited by the specific embodiments disclosed below.

[0025] In addition, in the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present utility model.

[0026] In the present utility model, unless otherwise clearly defined and limited, the terms "installed", "connected", "connected", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be directly connected, or indirectly connected through an intermediate medium, and may be the internal communication of two elements or the interaction relationship between two elements. However, indicating a direct connection means that there is no connection relationship constructed through an excessive structure between the two connected main bodies, and only a connection structure is used to connect and form a whole. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] In the present utility model, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. In the description of this specification, the description referring to terms such as "one embodiment", "some embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0028] In the present utility model, as Figures 1 to 5As shown in the figure, an automatic opening and closing protective cover for a plate and frame filter press is provided, which can cover the top of the plate and frame filter press, including: a protective cover, including a flexible cover 2 and a lifting ring 3 provided at the top of the cover 2. The cover 2 is provided with a plurality of lifting areas at intervals in the length direction of the plate and frame filter press 1. At least two lifting rings 3 are provided at intervals in the width direction of the plate and frame filter press 1 within the lifting area of the cover 2; a driving assembly, including a driving rope 4 extending along the length direction of the plate and frame filter press and a driving part for driving the driving rope 4 to move horizontally. The driving rope 4 can pass through a plurality of lifting rings 3, so that when the driving rope 4 moves horizontally, it can drive the lifting rings 3 to move to drive the cover 2 to fold or unfold.

[0029] As shown in the figure, when the protective cover of the present utility model is in the folded state, it is stored at one end of the plate and frame filter press 1. When protection is required, the driving part drives the driving rope 4 to drive the lifting ring 3 to move towards the other end of the plate and frame filter press 1, thereby gradually unfolding the cover 2. When the lifting ring 3 is driven to the rightmost limit position where it can move, slipping occurs between the driving rope 4 and the lifting ring 3, and the driving rope 4 moves until the cover 2 is completely opened and then stops moving. When it is necessary to store the cover 2, the driving rope 4 can be moved in the reverse direction, and the driving rope 4 gradually drives the lifting ring 3 towards the left end direction of the plate and frame filter press 1 to complete the folding and storage of the cover 2. At this time, the upper side of the main body part of the plate and frame filter press 1 is open, reducing the occupation of the upper side space of the plate and frame filter press 1 by the protective cover, and facilitating maintenance operations on the upper side of the plate and frame filter press 1.

[0030] In the embodiment shown in the figure, two driving ropes are provided, and the two driving ropes respectively pass through a plurality of lifting rings. This is not a limitation to the present utility model. In an alternative embodiment, 1 or more than 2 driving ropes can also be used.

[0031] In a preferred embodiment, for the structure of the present utility model, a further optimized setting is that, as shown in the figure, the protective cover further includes a plurality of inner support rods 5 extending along the width direction of the plate and frame filter press 1. The inner support rods 5 are located in the lifting area, and the lifting rings 3 are respectively provided at both ends of the inner support rods 5. By providing the inner support rods, the cover 2 can be supported in the width direction of the plate and frame filter press 1, further stabilizing the shape of the cover 2, and also enabling the parts at both ends of the inner support rods to move approximately synchronously during the unfolding and contraction processes of the cover 2, so that the cover 2 can be unfolded and contracted smoothly.

[0032] In a preferred embodiment, for the structure of the present utility model, a further optimized setting is that both ends of the inner support rod 5 are bent downward and extended. This can further maintain the shape stability of the cover 2.

[0033] In a preferred embodiment, for the structure of the present utility model, a further optimized setting is that the protective cover further includes a supporting rod 6 extending along the length direction of the plate-frame filter press, and the driving rope 4 is arranged on the top surface of the supporting rod 6.

[0034] By providing the supporting rod 6, the height of the hanging ring 3 can be kept stable to prevent the middle part of the cover 2 from sagging when it unfolds.

[0035] In the illustrated embodiment, for the structure of the present utility model, more specifically, an arc-shaped groove 7 is provided on the top surface of the supporting rod 6, and the driving rope 4 is arranged in the arc-shaped groove 7. The top of the part of the driving rope 4 in the arc-shaped groove 7 is supported on the inner edge of the hanging ring 3. As shown in the figure, by providing the arc-shaped groove 7, the lateral movement of the driving rope 4 on the top of the supporting rod 6 can be restricted to further maintain the stability of the movement of the driving rope 4.

[0036] In the illustrated embodiment, for the structure of the present utility model, more specifically, the gap width between the hanging ring 3 and the side surface of the supporting rod 6 is smaller than the width of the driving rope 4.

[0037] As shown in the figure, the supporting rod 6 passes through the inside of the hanging ring 3. By controlling the gap between the side surface of the supporting rod 6 and the inner edge of the hanging ring 3, it is possible to prevent the driving rope 4 from slipping to the side of the supporting rod 6 during the process of driving the hanging ring 3 to move, and further prevent the driving rope 4 from being squeezed and stuck between the hanging ring 3 and the supporting rod 6.

[0038] In the illustrated embodiment, in order to further improve the structural stability of the supporting rod 6, a reinforcing pipe is further provided on one side of the supporting rod 6. The reinforcing pipe is connected to the supporting rod 6 through a connecting rib, and the hanging ring 3 is provided with a notch for the connecting rib to pass through at the position where the connecting rib passes.

[0039] In the illustrated embodiment, for the structure of the present utility model, more specifically, the width of the arc-shaped groove 7 is greater than the width of the driving rope 4.

[0040] As shown in the figure, this can reduce the contact area between the driving rope 4 and the groove wall of the arc-shaped groove 7 and reduce the resistance of the driving rope 4 moving on the top surface of the supporting rod 6.

[0041] In the illustrated embodiment, for the structure of the present utility model, more specifically, the top of the inner edge of the hanging ring 3 is coated with a wear-resistant layer 8. This can reduce the wear on the hanging ring 3 and the driving rope 4.

[0042] Preferably, the wear-resistant layer 8 can be a plastic wear-resistant ring to reduce the wear of the driving rope 4. After the wear-resistant layer 8 is worn, the plastic wear-resistant layer 8 can be replaced regularly.

[0043] In the illustrated embodiment, with respect to the structure of the present utility model, more specifically, guide wheels 9 are respectively provided at both ends of the supporting rod 6, and the driving rope 4 bypasses the guide wheels 9. As shown in the figure, by providing the guide wheels 9, the driving rope 4 can be guided to move at the end position of the supporting rod 6, so as to reduce the wear on the edge of the supporting rod 6.

[0044] In the illustrated embodiment, with respect to the structure of the present utility model, more specifically, the driving part includes a driving motor 10 and a driving wheel 11 connected to the driving motor, and the driving rope 4 bypasses the driving wheel 11.

[0045] As shown in the figure, two supporting rods 6 are provided at the top of the plate-and-frame filter press 1, and a driving rope 4 and a driving motor 10 are respectively provided at the positions of the two supporting rods 6. The driving motor 10 is arranged at the right end of the filter press, and a reversing wheel is arranged at the left end of the filter press. The driving rope 4 forms a rotating loop after bypassing the reversing wheel and the driving wheel 11. In a preferred embodiment, a tensioner may also be provided on the rotation path of the driving rope 4 to keep the driving rope 4 taut.

[0046] Each embodiment in the specification is described in a progressive manner. The same or similar parts among the embodiments can be referred to each other, and the key point of each embodiment is to illustrate the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can refer to the partial description of the method embodiment.

[0047] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
