Description

Technical Field

[0001] The utility model relates to the field of sludge dehydration filter press equipment, in particular to a sludge filter press cleaning mechanism. Background Art

[0002] For sludge carbonization treatment, drying and dehydration before the sludge enters the carbonization furnace is a key step. Currently, sludge dehydration is mostly performed through plate and frame filter presses. Existing plate and frame filter presses occupy a large area and require chemical adjustment during the filtration process, increasing treatment costs.

[0003] Patent application number 202010077042.0 discloses a deep sludge filter press dewatering shaft and dewatering method. This method utilizes multiple stations to perform different operations on the filter press drum, utilizing a vertical hydraulic cylinder for ultra-high-pressure filtration. During the filter cloth operation, a retractable filter drum support plate is installed at the bottom of the drum. This method requires repeated movement of the drum and installation and removal of the filter cloth, resulting in a complex process.

[0004] Based on the aforementioned background, the applicant has proposed an ultra-high-pressure filter press device capable of continuous operation at a single station. The device folds a filter cloth into an S-shape within a fixed filter cage, spreading the sludge to be filtered between the cloths. The upper end of the filter cloth is wound around a filter cloth drum outside the filter cage, while the lower end is fixed to the bottom wall of the filter cage. After the filtration is completed, the filter cloth is reeled in by the filter cloth drum, removing the sludge from the filter cloth surface. The applicant has provided a reversing roller and a scraper 16 within the filter cage to scrape off the sludge from the filter cloth surface before the filter cloth is reeled out of the filter cage. However, sludge still remains on the filter cloth surface when it is reeled into the filter cloth drum, which can easily cause the filter cloth drum to stick after reeling. Therefore, the applicant has proposed a sludge filter press cleaning mechanism to further clean the remaining sludge from the filter cloth before reeling. Utility Model Content

[0023] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

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

[0025] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] In this utility model, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integration; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or an interaction between two components. However, the phrase "direct connection" indicates that the two connected entities are not connected through an intermediate structure, but are connected to form a whole through a connecting structure. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0027] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0028] In this utility model, if Figure 1-4 As shown, a cleaning mechanism for sludge filter press is provided, including a cleaning water tank 1, a cleaning roller 2 is provided on the inner side of the cleaning water tank 1, and the cleaning water tank is formed with a first side wall 101 and a second side wall 102. The filter cloth 3 can be introduced into the cleaning water tank 1 through the first side wall 101 and then bypass the lower side of the cleaning roller 2 and be led out of the cleaning water tank 1 through the second side wall 102, so that when the water in the cleaning water tank 1 reaches the set liquid level, the filter cloth 3 on the lower side of the cleaning roller 2 can be immersed in water for cleaning.

[0029] The cleaning mechanism of the present invention is shown in the figure. When in use, as shown in the figure, the filter cloth drum 4 drives the filter cloth 3 to move upward after bypassing the reversing roller 15 when it is rewound upward. The scraper 16 scrapes the sludge on the surface of the filter cloth 3 at the position of the reversing roller 15. After the filter cloth 3 passes through the first side wall 101 of the cleaning tank and is introduced into the cleaning tank 1, the cleaning roller 2 makes the filter cloth 3 be located below the water surface in the cleaning tank 1, thereby removing the sludge remaining on the filter cloth 3 through the water in the cleaning tank 1. After the filter cloth 3 is drawn out, it is rewound onto the filter cloth drum 4, thereby reducing the possibility of the filter cloth drum 4 sticking.

[0030] In the embodiment shown in the figure, a further optimized arrangement of the present invention is that a cleaning brush 5 is provided on the lower side of the cleaning roller 2. As shown in the figure, by providing the cleaning brush 5, the cleaning effect can be further improved.

[0031] In the illustrated embodiment, a further optimized setting of the present invention is that a support rod 6 is provided on the lower side of the cleaning roller 2, and the support rod can support the filter cloth 3; the support rod is connected to the cleaning roller through a connecting bracket 7, and the connecting bracket 7 is configured to be liftable.

[0032] As shown in the figure, by configuring the cleaning roller 2 and the supporting rod to be liftable, the cleaning roller 2 can be lowered below the liquid level in the cleaning water tank 1 to clean the filter cloth 3 when the filter cloth reel 4 rewinds the filter cloth 3. When the filter cloth reel 4 lowers the filter cloth 3, the cleaning roller 2 and supporting rod 6 can be raised upward to lift the filter cloth 3 out of the cleaning water tank 1, thereby separating the filter cloth 3 from the cleaning brush 5 when the cleaning brush 5 is installed. Furthermore, by lifting the filter cloth 3 upward, the contact between the filter cloth 3 and the water in the cleaning water tank 1 is reduced when the filter cloth 3 is lowered. Preferably, the connecting bracket can be driven up and down by an oil cylinder.

[0033] In the illustrated embodiment, more specifically, as shown in the figure, the cleaning mechanism further includes a water outlet member arranged on the upper side of the second side wall 102, and the water outlet member is provided with a downward-facing water outlet 8.

[0034] As shown in the figure, before the filter cloth 3 moves outward from the second side wall 102 , the filter cloth 3 can be cleaned by spraying water through the water outlet 8 , thereby further reducing the sludge residue on the surface of the filter cloth 3 .

[0035] In the illustrated embodiment, for the structure of the present invention, to be more specific, the second side wall 102 is configured as a water guide section 1011 inclined outward from bottom to top at least in the upper portion, and the water outlet is arranged on the upper side of the water guide section 1011.

[0036] As shown in the figure, when the filter cloth 3 moves out of the water surface toward the second side wall 102, the filter cloth 3 can automatically drain water before being sprayed by the water outlet, thereby discharging the sludge and water remaining on the surface of the filter cloth 3. This can further improve the efficiency of the water spraying cleaning process when the water outlet 8 sprays water. At the same time, the water sprayed from the water outlet 8 can slowly flow along the inclined second side wall 102 into the liquid surface of the cleaning tank 1 after passing through the filter cloth 3, reducing the turbidity caused by the impact of the spraying water on the liquid surface.

[0037] In the illustrated embodiment, more specifically, as shown in the figure, an arc-shaped guide plate 9 is provided at the upper end of the water guide section 1011. As shown in the figure, the arc-shaped guide plate 9 can be used to support the filter cloth 3 and can also assist the filter cloth 3 in scraping off residual spray water after the arc-shaped guide plate 9 contacts the filter cloth 3.

[0038] In the embodiment shown in the figure, a further optimized configuration of the present invention is that the arc-shaped guide plate 9 is provided with a drainage protrusion 10. The drainage protrusion 10 can further promote the scraping effect of the arc-shaped guide plate 9 on the residual water of the filter cloth 3.

[0039] In the illustrated embodiment, for further specific description of the present invention, the water outlet component includes a water outlet box 11, a necking section 12 is formed at the bottom of the water outlet box 11, and a water outlet 8 extending along the length direction of the water outlet box 11 is formed at the top of the necking section 12.

[0040] As shown in the figure, the water outlet 8 can be distributed in a linear long strip shape, so that the water outlet 8 can spray water more evenly when spraying downward.

[0041] In the illustrated embodiment, a further optimized configuration of the present invention is that a sludge discharge pipe 13 is provided at the bottom of the cleaning tank 1. This allows for regular discharge of sludge deposited in the cleaning tank 1. As shown in the figure, the sludge discharge pipe 13 is provided with a regulating valve, which can be opened to discharge the sludge.

[0042] In the illustrated embodiment, more specifically, the cleaning water tank 1 is provided with a sedimentation chamber 14 below the cleaning roller 2, and the sludge discharge pipe 13 is disposed at the bottom of the sedimentation chamber 14. As shown in the figure, this ensures that there is sufficient water depth below the cleaning roller 2 to deposit sludge, further reducing the turbidity effect caused by the filter cloth 3 and the water fluctuations in the cleaning water tank.

[0043] The various embodiments in this specification are described in a progressive manner. Similar parts between the various embodiments can be referred to in conjunction with each other. Each embodiment focuses on the differences between the other embodiments. In particular, the system embodiments are generally similar to the method embodiments, so the description is relatively simple. For relevant parts, refer to the description of the method embodiments.

[0044] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
