Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment equipment, specifically a sludge-laying moving bed for plastic sludge. Background Technology

[0002] Sludge treatment equipment refers to a series of mechanical devices that can dewater, dry, incinerate, or utilize the solid matter (i.e., sludge) separated from sewage. These devices are widely used in municipal, industrial, and agricultural fields. When treating sludge by filter press, the sludge is usually evenly spread on a single layer of filter cloth. Below the filter cloth is typically a porous support plate or filter screen to support the sludge and guide the filtrate out. While this equipment is simple in structure, low in cost, and easy to install and operate, sludge easily penetrates the filter cloth or accumulates unevenly, leading to localized "sludge run-out." Furthermore, the dewatering efficiency is low, and the filter cloth experiences unilateral stress and rapid wear. Therefore, we propose a moving bed for plastic sludge to address these issues. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides a sludge-laying moving bed for plastic sludge, solving the problems mentioned in the background section.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A sludge-laying moving bed for plastic sludge includes a support base, a bracket fixed to the top of the support base, slide rails fixed to the inner walls of both sides of the support base, reciprocating horizontal plates slidably connected inside the grooves of the slide rails, a filter plate fixed between two reciprocating horizontal plates, and racks fixed to the bottom of each reciprocating horizontal plate. A rotating shaft is rotatably connected between the inner walls of both sides of the support base via bearings, and two transmission gears are fixed to the surface of the rotating shaft, each transmission gear meshing with a corresponding rack. A sludge pump is mounted on the top of the two reciprocating horizontal plates, and a moving base is fixed to the top of the two reciprocating horizontal plates. A drive roller is rotatably connected between the inner walls of both sides of the moving base via bearings, a pressure traction roller assembly is provided on the moving base, and a cloth roller assembly is provided inside the support base.

[0008] Furthermore, the pressure traction roller assembly includes a U-shaped plate that slides on a movable seat. A roller body is rotatably connected between the inner walls of the two sides of the U-shaped plate via bearings. A cylinder is fixed to the top of the movable seat. The top end of the cylinder slides through the movable seat and extends below it, and is fixedly connected to the U-shaped plate. Two guide rods slide through the top of the movable seat, and the bottom ends of the guide rods are fixedly connected to the U-shaped plate.

[0009] Furthermore, the fabric roller assembly includes a lower fabric roller and an upper fabric roller rotatably connected inside the support base via bearings.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a sludge-laying moving bed for plastic sludge, which has the following beneficial effects:

[0015] This invention involves evenly spreading the conditioned sludge between two layers of filter cloth using a sludge pump, while simultaneously advancing the upper and lower filter cloths in the cloth roller assembly. This creates a "filter cloth-sludge-filter cloth" sandwich structure, preventing sludge leakage during filtration. The reciprocating horizontal plate drives the moving seat to move back and forth. By employing a forward-backward-forward spreading method, the sludge sandwiched between the two filter cloths enters the vertical porous filter chamber of the filter press on one side of the bed in a Z-shape. Because the sludge is subjected to uniform force during compression, water is discharged along the gap between the two filter cloths, resulting in high dewatering efficiency. Furthermore, the use of double-sided filter cloth reduces the load on a single layer, extending its service life. Attached Figure Description

[0022] 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.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, an embodiment of this utility model proposes a sludge-laying moving bed for plastic sludge, including a support base 1, a bracket 2 fixed to the top of the support base 1, slide rails 3 fixed to the inner walls of both sides of the support base 1, reciprocating horizontal plates 4 slidably connected inside the grooves of the slide rails 3, a filter plate 5 fixed between the two reciprocating horizontal plates 4, and a rack 6 fixed to the bottom of each reciprocating horizontal plate 4. A rotating shaft 7 is rotatably connected between the inner walls of both sides of the support base 1 via bearings, and two transmission gears 8 are fixed to the surface of the rotating shaft 7. The transmission gears 8 are respectively meshed with the corresponding racks 6. A sludge pump 9 is installed on the top of the two reciprocating horizontal plates 4, and a scraper 16 is fixed at the sludge outlet of the sludge pump 9. The scraper 16 can be used to scrape the sludge discharged by the sludge pump 9. The moving bed is designed to maintain a consistent thickness. A movable seat 10 is fixed to the top of the two reciprocating horizontal plates 4. Two connecting plates 14 are fixed to one side wall of the movable seat 10. An auxiliary roller 15 is rotatably connected between the two connecting plates 14 via bearings. This auxiliary roller 15 guides the two layers of filter cloth after the drive roller 11 has moved, further assisting in folding the upper and lower filter cloths into a Z-shape after the sludge is laid. The drive roller 11 is rotatably connected between the inner walls of both sides of the movable seat 10 via bearings. A pressure traction roller assembly 12 is installed on the movable seat 10, and a cloth roller assembly 13 is installed inside the support base 1. During the process of using this plastic sludge moving bed, after placing the equipment in a suitable position, the plastic sludge conveying pipe can be connected and fixed to the inlet pipe of the sludge pump 9. Start-up... The cloth roller assembly 13 unfolds the upper and lower layers of filter cloth. At this time, the sludge discharged from the sludge pump 9 will be located between the upper and lower layers of filter cloth. Then, the motor is started to drive the drive roller 11 to rotate, which can drive the upper and lower layers of filter cloth after the sludge is placed forward. The pressure traction roller assembly 12 can squeeze the sludge under the two layers of filter cloth to the upper limit, so as to make the sludge spread evenly. At the same time as spreading the sludge, the forward and reverse motor can be started to drive the rotating shaft 7 to rotate. After the rotating shaft 7 rotates, it will drive the two transmission gears 8 to rotate. After the two transmission gears 8 rotate, they will drive the two racks 6 to move back and forth. When the two racks 6 move, they will drive the two reciprocating horizontal plates 4 to move, which will drive the sludge pump 9 and the moving seat 10 to move back and forth. At this time, forward movement can be achieved. The sludge-laying method involves two layers of filter cloth, one in reverse and one in forward motion, which are then folded into multiple Z-shaped structures as shown in the diagram. Since a filter press is located on one side of the moving base 10 to press the sludge-laying filter cloth, the two Z-shaped layers of filter cloth are laid into the vertical porous filter chamber of the filter press. Finally, the filter is pressed, reducing sludge leakage and preventing overturning of the filter press due to uneven sludge distribution. Furthermore, during sludge laying, the plastic sludge discharged from the sludge pump 9 still contains some moisture. When the sludge is discharged onto the filter cloth by the sludge pump 9, the moisture in the plastic sludge can pass through the lower layer of filter cloth and fall onto the filter plate 5.The sludge then falls through filter plate 5 into the collection area of ​​support base 1. A drain hole is located on the back of support base 1, allowing the collected sludge and water to be discharged.

[0025] like Figure 2 As shown, in some embodiments, the pressure traction roller assembly 12 includes a U-shaped plate 1201 that slides on the movable seat 10. A roller body 1202 is rotatably connected between the inner walls of both sides of the U-shaped plate 1201 via bearings. A cylinder 1203 is fixed to the top of the movable seat 10. The top end of the cylinder 1203 slides through the movable seat 10 and extends below it, and is fixedly connected to the U-shaped plate 1201. Two guide rods 1204 slide through the top of the movable seat 10. The bottom ends of the guide rods 1204 are fixedly connected to the U-shaped plate 1201. In use, the roller body 1202 can be used to provide upper limit traction for the two layers of filter cloth after the sludge is laid, so as to make the sludge spread evenly. Activating the cylinder 1203 can adjust the height of the U-shaped plate 1201, thereby realizing the adjustment of the height of the roller body 1202 as needed. The guide rods 1204 can provide guidance and support for the U-shaped plate 1201, so as to make it more stable during the up and down movement.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the fabric roller assembly 13 includes a lower fabric roller 1301 and an upper fabric roller 1302 rotatably connected to the support base 1 via bearings. Both the lower fabric roller 1301 and the upper fabric roller 1302 have sprockets 1306 fixed to their surfaces. The two sprockets 1306 are connected by a chain 1307, allowing the lower fabric roller 1301 and the upper fabric roller 1302 to rotate synchronously under the action of a single motor, thus saving production costs. Two lower guide rollers 1303 are rotatably connected to the support base 1 via bearings on one side of the lower fabric roller 1301. Two transverse supports 1304 are fixed on the bracket 2. Two transverse frames 1304 are equidistantly connected by bearings to an upper guide roller 1305. In use, the filter cloth rolls can be placed on the lower cloth roller 1301 and the upper cloth roller 1302 respectively. The two are detachably connected. The lower guide roller 1303 and the upper guide roller 1305 provide support and guidance for the unfolded filter cloth on the lower cloth roller 1301 and the upper cloth roller 1302. In addition, an upper adjustment mechanism for guiding the upper filter cloth is provided on the two transverse frames 1304, and a lower adjustment mechanism for guiding the lower filter cloth is provided on the support base 1. However, the upper and lower adjustment mechanisms are not shown in the figure.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
