Description

Technical Field

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

[0002] For sludge carbonization, drying and dehydration before the sludge enters the carbonization furnace is a critical step. The applicant has proposed a novel filter press solution. This involves stacking filter cloths in an S-shape within a filter cage, spreading the sludge to be filtered between the cloths, and then using a vertical compression component (a hydraulic cylinder driving a pressure block) to press the cloths downward, achieving ultra-high-pressure filtration. This is exemplified by the filtration method used in a sludge filter press device for a deep sludge filter press dehydration system, as disclosed in patent application number 202010077038.4.

[0003] When feeding sludge to be filtered onto the filter cloth, the applicant inserts the sludge into the upper side of the filter cloth through a slurry supply pipe. During the sludge discharge process, the sludge is gradually withdrawn from the slurry supply pipe, making the sludge more evenly distributed on the filter cloth. The sludge is spread horizontally after entering the filter cloth. Since the sludge spreads horizontally with a certain degree of randomness, it tends to be biased to one side. Based on this, the applicant has proposed a spreading mechanism to ensure a more even movement of the sludge when spreading horizontally on the filter cloth. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a distribution mechanism for a sludge filter press, which can promote more uniform spreading of sludge on the filter cloth, effectively solving the problems existing in the prior art.

[0005] In order to solve the above problems, the utility model provides a distribution mechanism of a sludge filter press, wherein the distribution mechanism includes a distribution pipe arranged at the discharge end of the slurry supply pipe, and side discharge ports are respectively provided on both sides of the distribution pipe. The distribution pipe is provided with a main discharge port in the direction where the side discharge port is away from the slurry supply pipe, and the projections of the two side discharge ports in the axial direction of the distribution pipe are located on both sides of the main discharge port.

[0006] Furthermore, the material distribution pipe is provided with a guide plate on the lower side of the side discharge port.

[0007] Furthermore, the guide plate extends obliquely outward and downward.

[0008] Furthermore, the top wall of the distribution pipe at a section of the side discharge port away from the slurry supply pipe is gradually inclined outward and downward.

[0009] Furthermore, the cross-section of the distribution pipe at the position of the side discharge port is circular, and at least a portion of the side discharge port is located below the center line of the distribution pipe.

[0010] Furthermore, the bottom wall of the material distribution pipe at the main material outlet position is provided with a plurality of discharge notches, and the discharge notches penetrate the end of the material distribution pipe away from the slurry supply pipe.

[0011] Furthermore, the width of the discharge notch gradually increases in a direction away from the slurry supply pipe.

[0012] Furthermore, the material distribution pipe and the slurry supply pipe are separate structures.

[0013] Furthermore, the material distribution pipe and the slurry supply pipe are connected through a flange.

[0014] Furthermore, the slurry supply pipe is provided with a screw conveyor, and the material distribution pipe is provided as a plastic material distribution pipe.

[0015] The beneficial effect of the utility model is that it can promote the sludge to be spread more evenly on the filter cloth, and effectively solves the problems existing in the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] In this utility model, if Figure 1-4As shown, a distribution mechanism of a sludge filter press is provided, which includes a distribution pipe 2 arranged at the discharge end of a slurry supply pipe 1, and side discharge ports 3 are respectively provided on both sides of the distribution pipe 2. The distribution pipe 2 is provided with a main discharge port 4 in the direction where the side discharge port 3 is away from the slurry supply pipe 1, and the projections of the two side discharge ports 3 in the axial direction of the distribution pipe 2 are located on both sides of the main discharge port 4.

[0028] When the cloth structure of the present invention is in use, as shown in the figure, when the slurry supply pipe 1 discharges sludge outward, the sludge is first discharged onto the filter cloth through the side discharge ports 3 on both sides of the cloth pipe 2, so that the side discharge ports 3 form two sludge discharge areas on the filter cloth. Since the slurry supply pipe 1 is gradually withdrawn outward in a direction away from the cloth pipe 2, the discharge position of the main discharge port 4 lags behind the side discharge port 3. The sludge discharged from the main discharge port 4 promotes the lateral spreading of the sludge discharged from the side discharge port 3 when paving horizontally. Accordingly, the sludge discharged from the side discharge port 3 forms a certain degree of resistance to the lateral spreading of the sludge discharged from the main discharge port 4, thereby reducing the degree of paving deviation caused by the rapid paving of the sludge discharged from the main discharge port 4 to one side.

[0029] In the illustrated embodiment, a further optimization of the present invention is that, as shown, the distribution pipe 2 is provided with a guide plate 5 below the side discharge port 3. As shown, the guide plate 5 prevents sludge flowing out of the side discharge port 3 from adhering to the surface of the distribution pipe 2. The guide plate 5 also allows for greater lateral spacing of the sludge, further improving sludge paving uniformity.

[0030] In the embodiment shown in the figure, a further optimization of the present invention is that the guide plate 5 extends outwardly and obliquely downwardly. As shown in the figure, this can promote the rapid sliding of sludge on the surface of the guide plate 5 and reduce the residual sludge on the guide plate 5.

[0031] In the illustrated embodiment, a further optimization of the present invention is that the top wall of the distribution pipe 2 at the section facing away from the slurry supply pipe 1 at the side discharge port 3 gradually slopes downward outward. As shown in the figure, an inclined discharge plate is provided within the distribution pipe 2, forming the top wall of the inner cavity of the distribution pipe 2 near the main discharge port 4. This reduces the flow diameter of the distribution pipe 2 when the sludge flows to the discharge plate, increasing the sludge pressure and promoting its discharge from the side discharge port 3.

[0032] In the illustrated embodiment, for the structure of the present invention, more specifically, the cross-section of the distribution pipe 2 at the position of the side discharge port 3 is circular, and at least a portion of the side discharge port 3 is located below the center line of the distribution pipe 2.

[0033] In the illustrated embodiment, a further optimized configuration of the present invention is that the bottom wall of the distribution pipe 2 is provided with a plurality of discharge notches 6 at the location of the main discharge port 4. The discharge notches 6 penetrate the end of the distribution pipe 2 on the side away from the slurry supply pipe 1. As shown in the figure, the provision of the discharge notches 6 allows the main discharge port 4 to discharge sludge simultaneously with the discharge notches 6. The discharge notches 6 disperse the discharged sludge, making the discharge of sludge from the main discharge port 4 smoother. The discharge notches 6 also allow the sludge discharged from the discharge notches 6 to be more evenly spread laterally after landing on the filter cloth.

[0034] In the illustrated embodiment, a further optimization is that, as shown in the figure, the width of the discharge notch 6 gradually increases in a direction away from the slurry supply pipe.

[0035] In a preferred embodiment, as shown in the figure, the structure of the present invention is further specifically described as follows: the distribution pipe 2 and the slurry supply pipe 1 are separate structures. This allows the distribution pipe 2 to be processed separately, making it easier to process the side discharge port 3 and guide plate 5 of the distribution pipe 2.

[0036] In an alternative embodiment, the material distribution pipe 2 and the slurry supply pipe 1 can also be provided integrally.

[0037] In the illustrated embodiment, with respect to the structure of the present invention, to be more specific, the material distribution pipe 2 is connected to the slurry supply pipe 1 via a flange 7 .

[0038] In the illustrated embodiment, more specifically, the slurry supply pipe 1 is provided with a screw conveyor 8 , and the material distribution pipe 2 is provided as a plastic material distribution pipe 2 .

[0039] 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.

[0040] 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 changes 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.
