Description

Technical Field

[0001] This utility model relates to the field of dyeing and printing wastewater treatment technology, and in particular to a wool filter machine. Background Technology

[0002] The dyeing and printing industry is one of my country's traditional advantageous industries, occupying an important position in the national economy. However, the dyeing and printing production process generates a large amount of wastewater with complex components, containing dyes, auxiliaries, and fiber impurities shed from fabrics, especially suspended solids such as cotton lint. These cotton lint impurities mainly originate from the mechanical friction and chemical treatment of fabrics during the dyeing and finishing process, and their size ranges from short fibers at the micrometer level to fiber bundles at the centimeter level, forming a stable suspended system in the wastewater.

[0003] Currently, the traditional treatment method commonly used by dyeing and printing enterprises is to first discharge production wastewater into large wastewater ponds for natural sedimentation. This method has many drawbacks: First, wastewater ponds occupy a large area, have high construction costs, and have low sedimentation efficiency, requiring several hours or even tens of hours to achieve initial solid-liquid separation; second, the sludge and cotton lint accumulated at the bottom of the sedimentation pond are rich in organic matter, which can produce a large amount of flammable and explosive gases such as biogas under anaerobic conditions, creating serious safety hazards, and poisoning, explosions, and other safety accidents may occur every year when cleaning the wastewater pond; third, the natural sedimentation method has limited effectiveness in removing fine cotton lint, and a large amount of suspended solids will still enter the subsequent treatment system, resulting in a persistently high chemical oxygen demand (COD) in the wastewater treatment system, increasing the burden on subsequent biological treatment and the consumption of reagents.

[0004] With increasingly stringent environmental protection requirements and growing awareness of water resource recycling, the dyeing and printing industry faces enormous pressure to reduce emissions and demand for water reuse. High COD not only increases wastewater treatment costs but also restricts water reuse rates. Cotton fibers and other impurities are significant sources of COD, making their effective removal a crucial step in dyeing and printing wastewater treatment. While existing filtration equipment such as bar screens and sieves can remove some large particles, they are prone to clogging and inconsistent treatment results when dealing with the large quantities of cotton fibers in dyeing and printing wastewater, making it difficult to meet the needs of continuous production. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a filter press with a reasonable structure and good filtration effect, which can effectively remove impurities such as cotton fibers from dyeing and printing wastewater, reduce COD, realize the recycling of wastewater or create favorable conditions for subsequent treatment.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A filter press includes a housing, with a partition plate fixed to the left end of the housing, the partition plate dividing the interior of the housing into a clear liquid chamber and a turbid liquid chamber arranged on the left and right sides; a filter cartridge is rotatably connected in the turbid liquid chamber, the inner cavity of the filter cartridge is connected to the clear liquid chamber; the filter cartridge is connected to a first motor that drives it to rotate, the first motor is fixed to the outside of the housing. The box is equipped with an inlet pipe that communicates with the turbid liquid chamber and an outlet pipe that communicates with the clear liquid chamber.

[0007] Wastewater from dyeing and printing containing impurities such as cotton fibers enters the turbid liquid chamber through the inlet pipe. The lower part of the filter cartridge is immersed in the wastewater, while the upper part is above the wastewater level. A first motor drives the filter cartridge to rotate. After filtration, impurities such as cotton fibers are trapped on the outside of the filter cartridge, and the relatively clear water enters the inside of the cartridge, then flows into the clear liquid chamber and is discharged through the outlet pipe for recycling or further wastewater treatment. The filter cartridge significantly reduces impurities and COD in the wastewater.

[0008] Furthermore, the filter cartridge is provided with a brush roller at the upper front side, and an inclined discharge plate is provided below the brush roller; the brush roller is connected to a second motor that drives it to rotate, the second motor is fixed on the housing, the discharge plate is fixed in the side slot of the housing, and both the first motor and the second motor are electrically connected to the controller.

[0009] The second motor drives the brush rollers to rotate, and the brush rollers brush away the lint and other impurities attached to the surface of the filter cartridge, thereby ensuring the filtration effect of the filter cartridge. The lint and other impurities brushed off by the brush rollers are thrown onto the discharge plate under the action of centrifugal force and gravity, and then discharged through the discharge plate.

[0010] Furthermore, the filter cartridge includes a mandrel and a perforated roller arranged coaxially, with the outer side of the perforated roller covered with a wire mesh; the inner side of the perforated roller is attached to a plurality of circumferentially distributed axial support rods, and the axial support rods are connected to the mandrel through a radial support assembly. A baffle is fixed to the end of the perforated roller away from the clear liquid chamber. The baffle is inserted into and fixed on the spindle. One end of the spindle is connected to the first motor.

[0011] Furthermore, the radial support assembly includes a radial support rod fixedly connected to the axial support rod and a threaded sleeve fixedly connected to the mandrel. An adjusting screw is screwed onto the threaded sleeve, and the adjusting screw is fixedly connected to the inner end of the radial support rod. A locking nut is screwed onto the adjusting screw.

[0012] During the production and assembly of the roller, the adjusting screw and the radial support rod can rotate relative to each other. Because the perforated roller is made of rolled and welded iron plate, its roundness deviation is relatively large, making it difficult to insert the radial support assembly into the perforated roller in one go. Rotating the adjusting screw drives the radial support rod outward, which in turn drives the axial support rod outward, thus expanding the perforated roller outward. Simultaneously, the adjusting screw can be used to adjust the overall length of the radial support assembly, making the overall length of each radial support assembly as equal as possible, thereby making the perforated roller as circular as possible. After initial adjustment, rotating the locking nut, which rests against the end face of the threaded sleeve, initially locks the adjusting screw. Then, the adjusting screw and the radial support rod are welded together. By dividing the radial support assembly into multiple adjustable components, the installation of the perforated roller is facilitated.

[0013] Furthermore, a cylinder is fitted and fixed onto the isolation plate, the cylinder is inserted into the isolation ring, the isolation ring is fixed to one end of multiple axial support rods, and the other end of the multiple axial support rods is fixedly connected to the baffle. The inner diameter of the isolation ring is preferably set to be in clearance fit with the outer diameter of the cylinder.

[0014] After filtration, the water entering the filter cartridge passes through the cylinder into the clear water chamber, while the isolation ring acts as a barrier, reducing the amount of sewage from the turbid liquid chamber entering the filter cartridge.

[0015] Furthermore, a rubber ring is fixed to the isolation ring, and the rubber ring is attached to the outer wall of the cylinder. The rubber ring further enhances the isolation effect and prevents water in the turbid liquid chamber from entering the filter cartridge through the gap between the isolation ring and the cylinder.

[0016] Furthermore, the wire mesh is provided with multiple circumferentially distributed toothed racks, which are fixed to the perforated roller by screws.

[0017] The rack and pinion mechanism can lift larger impurities, such as strips, from the dyeing wastewater, thereby removing large impurities from the wastewater and further improving the decontamination and filtration effect.

[0018] Furthermore, the rack is V-shaped. The included angle between the two sides of the rack is 60-90°.

[0019] The outstanding effect of this utility model is: Compared with existing technologies, the rotary filter cartridge method can effectively remove impurities such as cotton fibers from dyeing and printing wastewater, significantly reduce COD, and create favorable conditions for wastewater reuse or subsequent treatment.

[0020] The combination of the brush rollers and the discharge plate enables the automatic removal and discharge of impurities from the surface of the filter cartridge, ensuring the continuous and stable operation of the equipment.

[0021] The adjustable design of the radial support assembly solves the problem of large roundness deviation of the perforated roller, simplifies the installation process, and reduces assembly difficulty.

[0022] The rack and pinion design enhances the ability to remove large impurities, further improving filtration efficiency. Attached Figure Description

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] The following is for reference Figures 1 to 6 The present invention will be described as follows: like Figure 1 , Figure 2 As shown, a filter press includes a housing 1. A partition plate 2 is fixed to the left end of the housing 1, dividing the interior of the housing 1 into a clear liquid chamber 101 and a turbid liquid chamber 102, arranged to the left and right respectively. A filter cartridge 3 is rotatably connected inside the turbid liquid chamber 102, and the inner cavity of the filter cartridge 3 communicates with the clear liquid chamber 101. The filter cartridge 3 is connected to a first motor (not shown in the figure) that drives its rotation, and the first motor is fixed to the outside of the housing 1. The housing 1 is provided with an inlet pipe 11 communicating with the turbid liquid chamber 102 and an outlet pipe 12 communicating with the clear liquid chamber 101.

[0027] During operation, dyeing wastewater containing impurities such as cotton fibers enters the turbid liquid chamber 102 through the inlet pipe 11. The lower part of the filter cylinder 3 is immersed in the wastewater, while the upper part is above the wastewater level. The first motor drives the filter cylinder 3 to rotate. After the wastewater is filtered through the filter cylinder 3, impurities such as cotton fibers are blocked on the outside of the filter cylinder 3. The filtered clean water enters the inside of the filter cylinder 3, then enters the clear liquid chamber 101 and is discharged through the outlet pipe 12.

[0028] like Figure 3 As shown, a brush roller 41 is provided on the upper front side of the filter cartridge 3, and an inclined discharge plate 42 is provided below the brush roller 41. The brush roller 41 is connected to a second motor (not shown in the figure) that drives it to rotate. The second motor is fixed to the housing 1, and the discharge plate 42 is fixed in the side slot 13 of the housing 1. The second motor drives the brush roller 41 to rotate, brushing away impurities such as lint adhering to the surface of the filter cartridge 3. The brushed-off impurities are thrown onto the discharge plate 42 under the action of centrifugal force and gravity, and then discharged through the discharge plate 42.

[0029] like Figure 1-3 As shown, the filter cartridge 3 includes a core shaft 31 and a perforated roller 32 arranged coaxially. The outer side of the perforated roller 32 is covered with a wire mesh 33. The inner side of the perforated roller 32 abuts against multiple circumferentially distributed axial support rods 34, which are connected to the core shaft 31 via radial support components 35. A baffle 36 is fixed to the end of the perforated roller 32 away from the clear liquid chamber 101. The baffle 36 is inserted into and fixed to the core shaft 31. One end of the core shaft 31 is connected to a first motor. Both the first motor and the second motor are electrically connected to the controller.

[0030] like Figure 4 As shown, the radial support assembly 35 includes a radial support rod 351 fixedly connected to the axial support rod 34 and a threaded sleeve 352 fixedly connected to the mandrel 31. An adjusting screw 353 is screwed onto the threaded sleeve 352. The adjusting screw 353 is fixedly connected to the inner end of the radial support rod 351, and a locking nut 354 is screwed onto the adjusting screw 353. During installation, the overall length of the radial support assembly 35 can be adjusted by rotating the adjusting screw 353 to ensure that the lengths of each radial support assembly are equal, thus guaranteeing the roundness of the perforated roller 32. After adjustment, the locking nut 354 is used for initial tightening, and then the adjusting screw 353 is welded to the radial support rod 351 for fixation.

[0031] like Figure 5 As shown, a cylinder 21 is sleeved and fixed on the isolation plate 2. The cylinder 21 is inserted into the isolation ring 37, which is fixed to one end of a plurality of axial support rods 34. A rubber ring 38 is fixed on the isolation ring 37, which abuts against the outer wall of the cylinder 21, effectively preventing sewage in the turbid liquid chamber 102 from entering the filter cartridge 3.

[0032] like Figure 1 , Figure 6 As shown, the wire mesh 33 is provided with multiple circumferentially distributed toothed racks 39, which are fixed to the perforated roller 32 by screws. The toothed racks 39 are V-shaped, with the included angle between the two sides between 60-90°, and are used to remove large impurities from the sewage.

[0033] The working process of this utility model is as follows: Dyeing wastewater enters the turbid liquid chamber 102 through the inlet pipe 11. The filter cylinder 3 rotates under the drive of the first motor, and the wastewater is filtered through the wire mesh 33, with impurities blocked on the outer surface of the filter cylinder 3. The filtered clean water enters the interior of the filter cylinder 3, passes through the cylinder 21 into the clear liquid chamber 101, and is discharged from the outlet pipe 12. Simultaneously, the brush roller 41 rotates under the drive of the second motor, brushing off impurities from the surface of the filter cylinder 3. The impurities are discharged along the discharge plate 42. The rack 39 rotates with the filter cylinder 3, scooping up large impurities from the wastewater; these large impurities can also be brushed off by the brush roller.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
