Description

Technical Field

[0001] This utility model relates to the field of mud applicator technology, specifically a mud applicator mechanism. Background Technology

[0002] A sludge distributor is a device that can uniformly disperse sludge and is widely used in sludge treatment. However, existing sludge distributors can only distribute sludge on the surface of a flat filter cloth in actual use, and cannot distribute sludge in the folded and closed filter cloth cavity. In the pressing cage, the flat filter screen is repeatedly folded and distributed with sludge. Since each layer of the flat filter screen is not a closed cavity, during the pressing and dewatering process, as the pressure increases, some of the wet sludge on the flat filter cloth will be squeezed out of the filter cloth and overflow into the upper part of the pressing plate along the gap between the pressing plate and the pressing cage. Only part of the sludge is pressed and dewatered, resulting in low sludge treatment capacity and efficiency. In addition, the internal cavity structure of the sludge distributor is simple, which leads to different pressures and different sludge outputs at each sludge outlet. The sludge distribution thickness on the filter cloth surface is also inconsistent and uneven. Therefore, to address the above problems, a sludge distribution mechanism is designed to better meet the actual needs. Utility Model Content

[0003] The purpose of this invention is to provide a mud-spreading mechanism to solve the problems mentioned in the background art, such as the inability to spread mud in a folded, closed filter cloth cavity and the uneven thickness of the mud spread.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mud-distributing mechanism, including a connecting flange fixed to the mud inlet on the right side of a mud-distributing pipe; the right end of the mud-distributing pipe is connected to a mud storage silo, the mud-distributing pipe and the mud storage silo forming a "U"-shaped structure; an arc-shaped plate is fixed to the lower side of the mud storage silo; the filter cloth is folded into three layers and installed such that the upper layer of filter cloth is above the mud-distributing pipe, the middle layer of filter cloth is in contact with the upper surface of the mud storage silo, and the lower layer of filter cloth is in contact with the arc-shaped plate, with the mud outlet on the arc-shaped plate located between the lower and middle layers of filter cloth; a first anti-scratch support rod is fixed to the upper surface of the mud-distributing pipe, a second anti-scratch support rod is fixed to the left side of the mud-distributing pipe, and reinforcing plates are symmetrically fixed to the front and rear of the mud-distributing pipe; one end of a connecting rod is fixed to the reinforcing plate, and the other end of the connecting rod is fixed to a push-cloth steering rod, which is in contact with the filter cloth.

[0005] Preferably, a reinforcing rib is fixed on the mud inlet on the right side of the mud conveying pipe, and the reinforcing rib is installed at an angle. The mud conveying pipe and the mud storage bin form a "U" shape. Through the action of the reinforcing rib, deformation and damage at the mud inlet of the mud conveying pipe can be avoided. The "U" shape formed by the mud conveying pipe and the mud storage bin can provide basic protection for the folding of the filter cloth.

[0006] Preferably, the first anti-scratch support rods are symmetrically distributed about the center line of the mud conveying pipe, and the upper end of the first anti-scratch support rods has an arc surface structure. The first anti-scratch support rods can slide in contact with the filter cloth, and the upper filter cloth can be supported by the first anti-scratch support rods, thereby providing a basic guarantee for the folding and mud-closing of the filter cloth.

[0007] Preferably, the mud storage bin is also fixed with horizontal plates at equal intervals, and vertical plates are evenly arranged between multiple sets of horizontal plates. The horizontal and vertical plates divide the internal space of the mud storage bin into a mud storage space that is larger at the top and smaller at the bottom. At the same time, the upper and lower mud storage spaces are connected by through holes. Through the action of the horizontal and vertical plates, a proportional flow guiding mechanism can be formed in the mud storage bin, thereby providing a basic guarantee for achieving uniform mud distribution.

[0008] Preferably, the sludge storage bin is also symmetrically fixed with arc-shaped third anti-scratch support rods, and the third anti-scratch support rods can slide in contact with the filter cloth. Through the action of the third anti-scratch support rods, the folded position of the filter cloth can be supported to ensure the normal movement of the filter cloth.

[0009] Preferably, the arc-shaped plate is positioned directly below the mud storage silo, and the arc-shaped plate is also provided with equally spaced arc-shaped mud outlets. Through the action of the arc-shaped plate and the mud outlets, uniform mud distribution can be achieved.

[0010] Preferably, the connecting rods are evenly distributed on the reinforcing plate, and the connecting rods are perpendicular to the reinforcing plate and the fabric pushing steering rod. The stability of the fabric pushing steering rod can be ensured through the action of multiple connecting rods.

[0011] Preferably, the pusher rods are symmetrically distributed about the center line of the mud conveying pipe, and the pusher rods can slide in contact with the filter cloth. Through the action of the pusher rods, the filter cloth can be limited, ensuring the stability of the filter cloth movement.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The sludge-laying mechanism adopts a U-shaped structure, which allows the device to lay sludge in the folded closed filter cloth cavity. These closed filter cloth cavities with sludge laid on them are repeatedly folded and stacked in the press cage, so that the wet sludge is completely in the closed cavity during the pressing and dewatering process. Therefore, the wet sludge will not be squeezed out of the filter cloth, which improves the sludge treatment capacity and efficiency. 2. The mud distribution mechanism, through the proportional flow guiding device composed of mud storage bin, horizontal plate and vertical plate, can ensure that the pressure of each mud outlet is the same and the mud output is the same, and the mud distributor distributes mud of the same thickness and uniformity on the filter cloth surface.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: a mud-distributing mechanism, including a connecting flange 1, which is fixed to the mud inlet on the right side of the mud conveying pipe 3; a first anti-scratch support rod 4 is fixed to the upper end face of the mud conveying pipe 3, a second anti-scratch support rod 5 is fixed to the left side of the mud conveying pipe 3, and reinforcing plates 6 are symmetrically fixed to the front and rear of the mud conveying pipe 3; the right end of the mud conveying pipe 3 is connected to the mud storage bin 7; an arc-shaped plate 9 is fixed to the lower side of the mud storage bin 7; one end of a connecting rod 10 is fixed to the reinforcing plate 6; and a cloth-pushing steering rod 11 is fixed to the other end of the connecting rod 10, which contacts the filter cloth 12.

[0017] A reinforcing rib 2 is fixed on the right side of the mud inlet of the mud conveying pipe 3, and the reinforcing rib 2 is installed at an angle. The mud conveying pipe 3 and the mud storage bin 7 form a "U" shaped structure. The first anti-scratch support rod 4 is symmetrically distributed about the center line of the mud conveying pipe 3, and the upper end of the first anti-scratch support rod 4 is an arc-shaped structure. The first anti-scratch support rod 4 can slide in contact with the filter cloth 12. The mud storage bin 7 is also symmetrically fixed with an arc-shaped third anti-scratch support rod 8, and the third anti-scratch support rod 8 can slide in contact with the filter cloth 12. The arc-shaped plate 9 is set directly below the mud storage bin 7, and the arc-shaped mud outlet 901 is opened at equal intervals on the arc-shaped plate 9. The connecting rod 10 is evenly distributed on the reinforcing plate 6, and the connecting rod 10 is perpendicular to the reinforcing plate 6 and the push cloth steering rod 11. The push cloth steering rod 11 is symmetrically distributed about the center line of the mud conveying pipe 3, and the push cloth steering rod 11 can slide in contact with the filter cloth 12. When using this filter cloth mechanism, first assemble the entire device with the folded filter cloth 12, as follows: Figure 2 and Figure 4 As shown, at this time, the upper filter cloth 12 contacts the first anti-scratch support rod 4 and the push cloth steering rod 11 to achieve guidance, the middle filter cloth 12 contacts the upper end surface of the sludge storage bin 7 to achieve guidance, and the lower filter cloth 12 contacts the arc plate 9 to achieve guidance. At this time, the sludge outlet 901 is located between the lower filter cloth 12 and the middle filter cloth 12. With the sliding action between the filter cloth 12 and the second anti-scratch support rod 5 and the third anti-scratch support rod 8, the filter cloth 12 can form a folded sealed cavity, thereby realizing the folding of the filter cloth 12 for sludge application. The mud storage bin 7 is also fixed with horizontal plates 701 at equal intervals, and vertical plates 702 are evenly arranged between multiple sets of horizontal plates 701. The horizontal plates 701 and vertical plates 702 divide the internal space of the mud storage bin 7 into a mud storage space that is larger at the top and smaller at the bottom. The upper and lower mud storage spaces are connected by through holes. The arc plate 9 is located directly below the mud storage bin 7, and the arc plate 9 is also provided with arc-shaped mud outlets 901 at equal intervals. When applying mud, such as Figures 1-4 As shown, by connecting the flange 1 to the sludge feeding pipe, wet sludge can enter the sludge conveying pipe 3. Through the guiding effect of the sludge conveying pipe 3, the wet sludge can enter the sludge storage bin 7. With the help of the horizontal plate 701 and the vertical plate 702, the internal space of the sludge storage bin 7 is distributed, so that the sludge can move evenly from top to bottom, thereby achieving the equal proportion of wet sludge guiding effect. This ensures that the sludge pressure at the lower outlet of the sludge storage bin 7 is the same. After the sludge is discharged, it is evenly distributed on the arc plate 9 and evenly discharged through the sludge outlet 901 onto the lower filter cloth 12, thereby realizing the folding and sludge-covering function of the filter cloth 12. At this time, the folding of the filter cloth 12 can achieve the sealing of the wet sludge, preventing the sludge from overflowing during subsequent pressing and dewatering, and ensuring the sludge processing capacity and efficiency. This is the working principle of the sludge-covering mechanism.
