Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter cloth production technology, specifically a cotton collection box for making filter cloth for silt drainage and consolidation. Background Technology
[0002] The cotton collection box is one of the core pieces of equipment in the preparation process of filter cloth for sludge drainage consolidation. Its core function is to evenly spread and initially shape short fiber raw materials such as polyester filament and polypropylene filament, providing a stable fiber layer foundation for subsequent processes such as needle punching and hot melting. The device is usually composed of a fiber input system, an airflow control module, an extrusion molding device, and a discharge conveying mechanism. During use, the blower blows the short fibers into the box at a specific wind speed, and the suspended fibers form a stable flow field inside the box. When discharging, the flat layer is squeezed by the pressure rollers, which enhances the friction and mechanical interlocking force between the fibers, forming a fiber web with initial strength.
[0003] For example, Chinese patent CN115748097A, entitled "A Filter Cloth for Silt Drainage Consolidation and a Method for Preparing a Double-Sided Percolation Drainage Body," includes laying polyester and polypropylene filaments, which are then blown into a cotton collection box by a blower. After being extruded from the cotton collection box, the filaments enter a cylinder. The cylinder has several serrations, and the serrations have several notches facing the exit side. The polyester and polypropylene filaments are 5-8 mm in length. The drainage support frame includes a flat plate and protrusions perpendicular to the surface of the plate located on both sides of the plate. The protrusions and the plate form a harmonica-like structure, and the length direction of the protrusions is parallel to the length direction of the plate. A layer of filter cloth is arranged on both sides of the drainage support frame and heated by a second roller group to obtain the finished double-sided percolation drainage body. The heating temperature of the second roller group is 170-220°C, and there are two sets of the second roller group.
[0004] While the aforementioned existing technologies can achieve the production of filter cloth, in practical use, on the one hand, the thickness of a single filter cloth is difficult to adjust. Usually, the thickness of a single filter cloth is fixed after extrusion, which means that multiple filter cloths need to be extruded to form filter cloths of different thicknesses, thus reducing the efficiency of filter cloth production. On the other hand, raw material accumulation is prone to clumping. Usually, a large amount of raw material enters the box through the feed pipe, which leads to the accumulation and clumping of raw materials if they are not processed in time, thus affecting the production of filter cloth. Therefore, it does not meet the current needs. In response, we propose a cotton collection box for making filter cloths for sludge drainage consolidation. Utility Model Content
[0005] The purpose of this invention is to provide a cotton collection box for making filter cloth for silt drainage and consolidation, so as to solve the problems mentioned in the background art, such as the difficulty in adjusting the thickness of a single filter cloth and the easy formation of clumps when raw materials are stockpiled.

[0007] Preferably, a second motor is fixedly installed at the rear end of the lower part of the box body. The output shaft of the second motor extends into the box body and is rotatably connected to the box body. The output shaft of the second motor passes through the extrusion cylinder and is fixedly connected to the extrusion cylinder. Observation windows are provided at the center positions of the front and rear ends inside the box body, and the observation windows correspond to the positions of the extrusion cylinder.
[0008] Preferably, a third motor is fixedly installed on one side of the outer side of the fixed base, the output shaft of the third motor passes through and extends to the other side of the fixed base, and the output shaft of the third motor is fixedly connected to the fixed rod.
[0009] Preferably, airflow distribution plates are provided on both sides of the upper interior of the box, and air inlet pipes are provided on the upper sides of both exterior sides of the box. One end of the air inlet pipe extends into the interior of the box and communicates with the airflow distribution plates. The air inlet pipe located inside the box is a retractable structure.
[0010] Preferably, a first motor is fixedly installed on both the front and rear ends of the outer side of the housing, and the output shaft of the first motor extends into the interior of the housing and is fixedly connected to the airflow distribution plate.
[0011] Preferably, a frame is fixedly installed at the lower end of the box body outside the fixed base, and a fixed frame is fixedly installed at the upper end of the frame. Hydraulic telescopic devices are fixedly installed at both the front and rear ends of the upper end of the fixed frame. The lower end of the telescopic end of the hydraulic telescopic device extends to the bottom of the fixed frame. An extrusion plate is fixedly installed at the lower end of the telescopic end of the hydraulic telescopic device, and the extrusion plate corresponds to the position of the conveyor belt.
[0012] Preferably, a feed pipe is fixedly provided at the upper end of the box cover, the feed pipe is connected to the box body, and the feed pipe has a strip-shaped structure.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model can adjust the thickness of fiber raw material production by using an extrusion cylinder and a conveyor belt. When filter cloth is produced, the raw material has been evenly distributed. At this time, the second motor and the third motor are turned on by an external controller, so that the output shaft of the second motor drives the extrusion cylinder to rotate clockwise inside the box. The raw material is squeezed by the protrusion on the extrusion cylinder and falls onto the conveyor belt. At the same time, the output shaft of the third motor drives the fixed rod to rotate, and the fixed rod drives the belt roller to rotate, so that the belt roller drives the conveyor to move until the raw material is sent out from the discharge port. The operator controls the rotation of the second motor and the third motor through the controller to adjust the thickness of fiber raw material production, thereby improving the diversity of filter cloth production.
[0015] (2) This utility model can blow up fiber raw materials through the observation window and airflow distribution plate. When filter cloth is produced, the external air pump is turned on by the external controller. At this time, the airflow generated by the air pump enters the airflow distribution plate through the air inlet pipe, so that the airflow inside the box is generated at an angle. When the raw material enters the box through the feed pipe, the angled airflow will blow the raw material, so that the raw material forms a uniform suspension state in the box, avoiding local accumulation or voids. At the same time, the operator can check the state of the raw material through the observation window. If it is necessary to adjust the angle of the airflow distribution plate, the first motor is turned on by the controller, so that the output shaft of the first motor drives the airflow distribution plate to rotate inside the box until the airflow distribution plate is adjusted to a suitable angle, thereby improving the dispersion effect of the raw material.
[0016] (3) This utility model can flatten fiber raw materials by means of a hydraulic telescopic device and an extrusion plate. When filter cloth is produced, the raw materials are spread on the conveyor belt. The hydraulic telescopic device is activated by an external controller, so that the telescopic end of the hydraulic telescopic device extends. The extension of the hydraulic telescopic device drives the extrusion plate to move downward until the extrusion plate is moved to a suitable position. At this time, the raw materials on the conveyor belt of the extrusion plate are extruded. After one extrusion operation is completed, the working state of the hydraulic telescopic device is adjusted by the controller, so that the telescopic end of the hydraulic telescopic device retracts until the extrusion plate is separated from the raw materials. The above steps are repeated to flatten the raw materials multiple times, avoiding the need to add a compaction equipment in the traditional process, thereby shortening the production cycle.

A belt roller 18 is fixedly installed on the outside of the fixed rod 17. A conveyor belt 9 is sleeved on the outside of the belt roller 18. The lower part of the exterior of the housing 1... A second motor 16 is fixedly installed at the rear end. The output shaft of the second motor 16 extends into the housing 1 and is rotatably connected to the housing 1. The output shaft of the second motor 16 passes through the extrusion cylinder 15 and is fixedly connected to the extrusion cylinder 15. A third motor 19 is fixedly installed on one side of the outside of the fixed base 8. The output shaft of the third motor 19 passes through and extends to the other side of the fixed base 8. The output shaft of the third motor 19 is fixedly connected to the fixed rod 17. The fixed rods 17 on both sides provide the driving effect, and the remaining fixed rods 17 provide the supporting effect, which facilitates the adjustment of the production thickness of the filter cloth through the extrusion cylinder 15 and the conveyor belt 9.
[0025] Please see Figure 1 , Figure 2 and Figure 3Airflow distribution plates 14 are provided on both sides of the upper part of the box body 1. Air inlet pipes 5 are provided on the upper part of both sides of the outer side of the box body 1. One end of the air inlet pipe 5 extends into the interior of the box body 1 and communicates with the airflow distribution plate 14. The air inlet pipe 5 located inside the box body 1 is a telescopic structure. A first motor 4 is fixedly installed on both the front and rear ends of the outer side of the box body 1. The output shaft of the first motor 4 extends into the interior of the box body 1 and is fixedly connected to the airflow distribution plate 14. An observation window 6 is provided at the center of the front and rear ends of the inner side of the box body 1. The observation window 6 corresponds to the position of the extrusion cylinder 15, which facilitates the homogenization of the raw materials through the airflow distribution plate 14.
[0026] Please see Figure 1 and Figure 2 A frame 7 is fixedly installed at the lower end of the housing 1 outside the fixed base 8. A fixed frame 10 is fixedly installed at the upper end of the frame 7. A hydraulic telescopic device 11 is fixedly installed at both the front and rear ends of the upper end of the fixed frame 10. The lower end of the telescopic end of the hydraulic telescopic device 11 extends to the lower part of the fixed frame 10. An extrusion plate 12 is fixedly installed at the lower end of the telescopic end of the hydraulic telescopic device 11. The extrusion plate 12 corresponds to the position of the conveyor belt 9, so that the raw material can be flattened by the extrusion plate 12.
[0027] Working Principle: In operation, the external air pump is first activated via the external controller. The airflow generated by the pump enters the airflow distribution plate 14 through the air inlet pipe 5, creating an upward-sloping airflow inside the housing 1. When the raw material enters the housing 1 through the feed pipe 3, the upward-sloping airflow agitates the material, causing it to suspend evenly within the housing 1. Simultaneously, the operator observes the material's condition through the observation window 6. If the angle of the airflow distribution plate 14 needs adjustment, the first motor 4 is activated via the controller, causing its output shaft to rotate the airflow distribution plate 14 inside the housing 1 until the appropriate angle is achieved. During filter cloth production, the second motor 16 and the third motor 19 are activated via the external controller. The output shaft of the second motor 16 rotates the extrusion cylinder 15 clockwise inside the housing 1, squeezing the raw material through the protrusions on the extrusion cylinder 15 onto the conveyor belt 9. Simultaneously, the third motor... The output shaft of motor 19 drives the fixed rod 17 to rotate, and the fixed rod 17 drives the belt roller 18 to rotate, so that the belt roller 18 drives the conveyor to move until the raw material is sent out from the discharge port 13. The operator controls the rotation of the second motor 16 and the third motor 19 through the controller to adjust the thickness of the fiber raw material. At this time, the hydraulic telescopic device 11 is activated by the external controller, so that the telescopic end of the hydraulic telescopic device 11 extends. The extension of the hydraulic telescopic device 11 drives the extrusion plate 12 to move downward until the extrusion plate 12 is moved to a suitable position. At this time, the raw material on the conveyor belt 9 is extruded by the extrusion plate 12. After one extrusion operation is completed, and the conveyor belt 9 stops working during the extrusion operation, the working state of the hydraulic telescopic device 11 is adjusted by the controller, so that the telescopic end of the hydraulic telescopic device 11 retracts until the extrusion plate 12 is separated from the raw material. The above steps are repeated for multiple extrusions.
