Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to a dye pressure filtration device. Background Technology

[0002] In fabric processing, to achieve rich and lasting color effects, dyes are typically applied through physical or chemical bonding with fibers. Existing dyeing and printing equipment often proceeds directly to the drying process after dyeing without effectively treating excess dye liquor remaining on the fabric surface. This leads to dye liquor dripping during fabric movement and drying, resulting in dye waste, increased production costs, and potential contamination of equipment and the workshop environment, impacting on-site cleanliness and production safety.

[0003] A search revealed that patent CN222854836U discloses a dye pressure filtration device for fabric processing. This device features a pressing component that automatically adjusts to the thickness of the dyed fabric. A scraping component removes residual dye from the pressing component and the filter conveyor belt, preventing contamination of new fabric. A limiting component restricts the scraping component, facilitating its disassembly and assembly, and allowing for easy cleaning of the collected dye.

[0004] However, the above-mentioned device has the following drawbacks: the pressing element 201 relies on the first spring 201d to provide pressure. Long-term operation in dye and humid environments makes the spring prone to fatigue and corrosion, leading to changes in its elastic coefficient (k value). This causes the pressure applied to the fabric to gradually become unstable, or even fail. For thick fabrics, insufficient pressure may result in inadequate filtration, while for thin fabrics, excessive pressure may cause stretching or damage. Secondly, the device cannot filter the extruded dye liquor, which contains lint, affecting its recycling. Therefore, further improvements are needed. To this end, we propose a dye pressure filtration device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dye pressure filtration device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dye pressure filtration device, comprising a housing, a top cover fixed to the top of the housing, multiple support rollers horizontally rotatably connected inside the top cover, an extrusion assembly disposed above the multiple support rollers, a hydraulic telescopic rod fixed to the upper surface of the top cover, a pressure monitoring assembly connected between the bottom telescopic end of the hydraulic telescopic rod and the extrusion assembly, a filter assembly horizontally disposed at the top of the housing, and a reduction motor for driving the filter assembly to rotate installed on the outer wall of the housing, an opening on one side of the top of the housing, a vertical scraper fixed near the opening inside the housing, a filter screen fixedly connected between the scraper and the inner wall of the housing, a drain pipe installed on one side of the bottom of the housing, and a controller disposed on the surface of the housing.

[0007] Furthermore, the extrusion assembly includes a U-shaped plate with its opening facing downwards, and multiple extrusion rollers are rotatably connected inside the U-shaped plate, with the multiple extrusion rollers respectively located above multiple support rollers.

[0008] Furthermore, the pressure monitoring component includes a cylinder fixed to the telescopic end of the hydraulic telescopic rod, and a sliding rod is slidably connected inside the bottom end of the cylinder. The bottom end of the sliding rod is fixedly connected to a U-shaped plate. A pressure sensor is fixed to the top wall inside the cylinder. Both the pressure sensor and the hydraulic telescopic rod are electrically connected to the controller.

[0009] Furthermore, a sealing ring is fitted onto the surface of the slide rod, a threaded groove is provided on the outer wall of the slide rod, a strip-shaped opening is provided at the bottom end of the side wall of the cylinder, and a screw is slidably connected inside the strip-shaped opening, and the screw is rotatably connected inside the threaded groove, and a knob is fixed at the other end of the screw.

Filter cloth is fitted onto the surfaces of both the drive shaft and the driven shaft, and the output end of the geared motor is fixedly connected to the drive shaft.

[0011] Furthermore, the top of the scraper is attached to the lower surface of the filter cloth.

[0012] Furthermore, support plates are fixed to both the scraper surface and the inner wall of the box, and the filter screen is fixed to the surface of the support plates by bolts.

[0013] The beneficial effects of this utility model are:

[0014] 1. In use, this utility model includes a box, a top cover, several support rollers, an extrusion assembly, a hydraulic telescopic rod, and a pressure monitoring assembly. The dyed fabric passes between the support rollers and the extrusion assembly. The hydraulic telescopic rod drives the extrusion assembly to descend, thereby extruding the fabric through the support rollers and the extrusion rollers of the extrusion assembly, squeezing out the dyeing liquid from the fabric.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4 As shown, a dye pressure filtration device is disclosed, comprising a housing 1, a top cover 2 fixed to the top of the housing 1, multiple support rollers 3 horizontally rotatably connected inside the top cover 2, an extrusion assembly 4 disposed above the multiple support rollers 3, a hydraulic telescopic rod 5 fixed to the upper surface of the top cover 2, a pressure monitoring assembly 6 connected between the bottom telescopic end of the hydraulic telescopic rod 5 and the extrusion assembly 4, a filter assembly 7 horizontally disposed at the top of the housing 1, and a reduction motor 8 for driving the filter assembly 7 to rotate installed on the outer wall of the housing 1, an opening 101 opened on one side of the top of the housing 1, a vertical scraper 9 fixed inside the housing 1 near the opening 101, a filter screen 10 fixedly connected between the scraper 9 and the inner wall of the housing 1, a drain pipe installed on one side of the bottom of the housing 1, and a controller disposed on the surface of the housing 1.

[0025] In this embodiment, the controller is a screen-equipped controller, specifically a Siemens SIMATIC KP1200KP1212 Basic PN. The device is controlled by the controller's built-in program.

[0026] The extrusion assembly 4 includes a U-shaped plate 41 with its opening facing downwards. Multiple extrusion rollers 42 are rotatably connected inside the U-shaped plate 41, and the multiple extrusion rollers 42 are respectively located above multiple support rollers 3.

[0027] When the fabric passes between multiple support rollers 3 and multiple extrusion rollers 42, the dyeing liquid contained in the fabric can be squeezed out by using multiple extrusion rollers 42 and support rollers 3 to squeeze the fabric.

[0028] The pressure monitoring assembly 6 includes a cylinder 61 fixed to the telescopic end of the hydraulic telescopic rod 5, and a slide rod 62 is slidably connected inside the bottom end of the cylinder 61. The bottom end of the slide rod 62 is fixedly connected to the U-shaped plate 41. A pressure sensor 63 is fixed on the inner top wall of the cylinder 61. Both the pressure sensor 63 and the hydraulic telescopic rod 5 are electrically connected to the controller.

[0029] In this embodiment, the pressure sensor 63 is model EVTSENSOR EVT-12M-300N. When the hydraulic telescopic rod 5 is extended, it can drive the pressure monitoring component 6 and the extrusion component 4 to descend. After the extrusion roller 42 extrudes the fabric, the upward reaction force of the slide rod 62 acts on the pressure measuring end of the pressure sensor 63. The pressure sensor 63 feeds back the pressure signal to the controller. When the pressure value reaches the preset value of the controller, the controller controls the hydraulic telescopic rod 5 to stop extending, thereby facilitating the extrusion of fabrics of different types and thicknesses and ensuring a constant pressure value.

[0030] A sealing ring 64 is fitted onto the surface of the slide rod 62. A threaded groove 65 is provided on the outer wall of the slide rod 62. A strip-shaped opening 67 is provided at the bottom of the side wall of the cylinder 61. A screw 66 is slidably connected inside the strip-shaped opening 67. The screw 66 is rotatably connected inside the threaded groove 65. A knob is fixed at the other end of the screw 66.

[0031] The sliding of the screw 66 inside the slot 67 limits the movement of the slide rod 62, preventing it from detaching from the cylinder 61. The sealing ring 64 seals the top of the cylinder 61, providing good protection for the pressure sensor 63. When the sealing ring 64 needs to be replaced, the screw 66 is unscrewed from the threaded groove 65, allowing the slide rod 62 to be removed from the cylinder 61, thus facilitating the replacement of the sealing ring 64.

[0032] The filter assembly 7 includes a drive shaft 71 and a driven shaft 72. The drive shaft 71 and the driven shaft 72 are located on both sides inside the housing 1 and are rotatably connected to the housing 1 through bearings. The surfaces of the drive shaft 71 and the driven shaft 72 are covered with filter cloth 73. The output end of the geared motor 8 is fixedly connected to the drive shaft 71.

[0033] After the geared motor 8 starts, the drive shaft 71 drives the filter cloth 73 to rotate continuously. When the squeezed dyeing liquid falls on the surface of the filter cloth 73, the dyeing liquid is filtered through the filter cloth 73.

[0034] In this embodiment, an anti-slip structure is designed for the drive shaft 71 and the driven shaft 72. Specifically, the surface of the drive shaft 71 that contacts the filter cloth 73 is subjected to high-frequency quenching treatment to increase roughness and hardness. At the same time, high-strength bolts are used to fasten the two ends of the filter cloth 73 to the surface of the drive shaft 71, and tension rollers can be set to adjust the tension, thereby effectively preventing slippage.

[0035] The top of scraper 9 is attached to the lower surface of filter cloth 73.

[0036] When the filter cloth 73 rotates to the side of the scraper 9, the scraper 9 scrapes off the lint filtered from the surface of the filter cloth 73, and the lint falls onto the upper surface of the filter screen 10 along the surface of the scraper 9.

[0037] Support plates 11 are fixed to the surface of the scraper 9 and the inner wall of the housing 1, and the filter screen 10 is fixed to the surface of the support plates 11 by bolts. This makes the filter screen 10 removable, which is convenient for handling the lint on the surface of the filter screen 10.

[0038] Working principle: After dyeing, the fabric passes between multiple support rollers 3 and multiple extrusion rollers 42. The controller controls the hydraulic telescopic rod 5 to drive the extrusion assembly 4 to descend, and under the feedback of the pressure monitoring assembly 6, the extrusion force is controlled. The extruded dyeing liquid falls on the surface of the filter cloth 73 and is filtered through the filter cloth 73. At the same time, the reduction motor 8 drives the filter cloth 73 to rotate. When the filter cloth 73 rotates to the side of the scraper 9, the scraper 9 scrapes off the lint filtered from the surface of the filter cloth 73. The lint then falls along the surface of the scraper 9 onto the upper surface of the filter screen 10. After filtration, the dyeing liquid falls to the bottom of the box 1 for easy reuse.

[0039] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
