Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to a filtration device for waterborne polyurethane processing. Background Technology

[0002] Waterborne polyurethane is a novel polyurethane system that uses water instead of organic solvents as the dispersion medium. It is also called water-dispersible polyurethane, water-based polyurethane, or water-based polyurethane. Waterborne polyurethane uses water as a solvent and has advantages such as being pollution-free, safe and reliable, having excellent mechanical properties, good compatibility, and being easy to modify. While certain toxic solvents are used in the synthesis of polymer materials, their recycling and the reduction of their residue in the product can be ensured. This is also a research topic in the green synthesis of polymers. The synthesis of waterborne polyurethane resin is a typical example of this. The generated waterborne polyurethane products will contain a certain amount of waterborne polyurethane particles, skins, etc. To obtain a uniform and stable product, filtration is necessary.

[0003] A filtration device (CN217489985U) for waterborne polyurethane processing is available, comprising a base, a mounting frame, and a mounting assembly. A filter bag is detachably mounted on the lower end of the inner wall of the mounting frame via the mounting assembly. Rotating rods are movably mounted on both sides of the mounting frame, and an elliptical extrusion disc is fitted onto the surface of each rotating rod. A transmission assembly is installed inside the base, and a receiving box is located at the middle of the upper end of the base. The user places material onto the filter bag through the material inlet, facilitating filtration. The motor output drives a rotating ring to rotate via a meshing gear and a meshing toothed ring. The rotating ring, in turn, drives the rotating rod to rotate via a transmission gear and a transmission toothed ring. As the rotating rod rotates, it drives the elliptical extrusion disc to rotate, thus extruding the filter bag.

[0004] However, the aforementioned new type of filter uses a squeezing method during use, which cannot filter while feeding, resulting in low processing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a filtration device for waterborne polyurethane processing, which aims to solve the problem that existing devices filter by extrusion during use, cannot filter while feeding, and have low processing efficiency.

[0006] To achieve the above objectives, this utility model provides a filtration device for waterborne polyurethane processing, including a housing and a filtration assembly. The filtration assembly includes a support frame, a rotating component, a filter cylinder, a filter bag, a water outlet component, a housing cover, and a water inlet pipe.

[0007] The support frame is fixedly connected to the housing and located at the bottom of the housing. The rotating component is connected to the housing and located on one side of the housing. The filter cartridge is connected to the rotating component and located on one side of the rotating component. The filter bag is detachably connected to the filter cartridge and located inside the filter cartridge. The water outlet component is connected to the housing and located outside the housing. The housing cover is slidably connected to the housing and located at the top of the housing. The water inlet pipe is connected to the housing and located at the top of the housing.

[0008] The rotating component includes a motor and a turntable. The motor is fixedly connected to the housing and located on one side of the housing. The turntable is fixedly connected to the output end of the motor and rotatably connected to the housing, and located inside the housing.

[0009] The water outlet component includes a water outlet pipe and a control valve. The water outlet pipe is connected to the housing and located on one side of the housing. The control valve is connected to the water outlet pipe and located on one side of the water outlet pipe.

[0010] The filter assembly further includes a limiting groove and a protective shell. The limiting groove is fixedly connected to the box cover and located at the bottom of the box body. The filter cartridge is slidably connected to the limiting groove and located inside the limiting groove. The protective shell is detachably connected to the box body and located outside the box body.

[0011] The filtration assembly further includes a collection box and a filter plate. The collection box is located on one side of the water outlet pipe, and the filter plate is detachably connected to the collection box and located inside the collection box.

[0012] This utility model discloses a filtration device for processing waterborne polyurethane. A support frame supports the housing, and a housing cover is slidably mounted on the top of the housing. Waterborne polyurethane to be filtered is added to the filter bag inside the filter cartridge via the inlet pipe. The filter cartridge is then rotated by a rotating component, causing the filter bag inside the cartridge to rotate as well. During rotation, the waterborne polyurethane permeates through the filter bag and the filter cartridge during centrifugation and is discharged through the outlet component on the housing. Particulate impurities in the waterborne polyurethane are isolated by the filter belt during centrifugal filtration. The filter bag is detachably connected to the filter cartridge and can be periodically removed for replacement or cleaning. This device solves the problem of low processing efficiency in existing devices that filter by compression, cannot filter while feeding, and have low processing efficiency.

Figure 2 This is a cross-sectional schematic diagram of a filtration device for waterborne polyurethane processing according to the present invention.

[0020] This utility model provides a filtration device for waterborne polyurethane processing, comprising a housing 101 and a filter assembly 102. The filter assembly 102 includes a support frame 103, a rotating component 104, a filter cartridge 105, a filter bag 106, a water outlet component 107, a housing cover 108, a water inlet pipe 109, a motor 110, a turntable 111, a water outlet pipe 112, a control valve 113, a limiting groove 114, a protective shell 115, a collection box 116, and a filter plate 117. This solution solves the problem of low processing efficiency in existing devices that filter by compression, cannot filter while feeding, and therefore require simultaneous filtration.

[0021] In this embodiment, the support frame 103 is fixedly connected to the housing 101 and located at the bottom of the housing 101; the rotating member 104 is connected to the housing 101 and located on one side of the housing 101; the filter cartridge 105 is connected to the rotating member 104 and located on one side of the rotating member 104; the filter bag 106 is detachably connected to the filter cartridge 105 and located inside the filter cartridge 105; the water outlet member 107 is connected to the housing 101 and located outside the housing 101; the housing cover 108 is slidably connected to the housing 101 and located at the top of the housing 101; the water inlet pipe 109 is connected to the housing 101 and located at the top of the housing 101; and the support frame 103 is used to support the housing 101 and hold the housing cover... The filter bag 106 is slidably installed on the top of the housing 101. The water-based polyurethane to be filtered is added to the filter bag 106 inside the filter cartridge 105 through the water inlet pipe 109. Then, the filter cartridge 105 is rotated by the rotating component 104, which drives the filter bag 106 inside the filter cartridge 105 to rotate. During the rotation, the water-based polyurethane passes through the filter bag 106 and the filter cartridge 105 during centrifugation and is then discharged through the water outlet component 107 on the housing 101. Particulate impurities in the water-based polyurethane are isolated by the filter belt during centrifugal filtration. The filter bag 106 is detachably connected to the filter cartridge 105 and can be removed and replaced or cleaned periodically. This solves the problem of low processing efficiency in existing devices that filter by squeezing and cannot filter while feeding.

[0022] The rotating component 104 includes a motor 110 and a turntable 111. The motor 110 is fixedly connected to the housing 101 and located on one side of the housing 101. The turntable 111 is fixedly connected to the output end of the motor 110 and rotatably connected to the housing 101, and located inside the housing 101. The turntable 111 is driven to rotate by the motor 110, and the filter cartridge 105 rotates on the turntable 111, thereby causing the filter bag 106 inside the filter cartridge 105 to rotate.

[0023] Secondly, the water outlet component 107 includes a water outlet pipe 112 and a control valve 113. The water outlet pipe 112 is connected to the housing 101 and is located on one side of the housing 101. The control valve 113 is connected to the water outlet pipe 112 and is located on one side of the water outlet pipe 112. The filtered water in the housing 101 is discharged through the water outlet pipe 112. The control valve 113 is used to control the opening and closing of the water outlet pipe 112, thereby controlling the water output.

[0024] Furthermore, the filter assembly 102 also includes a limiting groove 114 and a protective shell 115. The limiting groove 114 is fixedly connected to the box cover 108 and is located at the bottom of the box body 101. The filter cartridge 105 is slidably connected to the limiting groove 114 and is located inside the limiting groove 114. The protective shell 115 is detachably connected to the box body 101 and is located outside the box body 101. The limiting groove 114 restricts the end of the filter cartridge 105 away from the turntable 111, preventing the filter cartridge 105 away from the turntable 111 from shaking violently during rotation. The protective shell 115 is used to protect the motor 110 and prevent the motor 110 from being damaged.

[0025] Finally, the filter assembly 102 also includes a collection box 116 and a filter plate 117. The collection box 116 is disposed on one side of the water outlet pipe 112. The filter plate 117 is detachably connected to the collection box 116 and is located inside the collection box 116. The collection box 116 is used to collect the water-based polyurethane discharged after filtration, and the water-based polyurethane is subjected to secondary filtration through the filter plate 117.

[0026] In the filtration device for waterborne polyurethane processing according to this utility model, the support frame 103 supports the housing 101, and the housing cover 108 is slidably installed on the top of the housing 101. The waterborne polyurethane to be filtered is added to the filter bag 106 inside the filter cartridge 105 through the water inlet pipe 109. Then, the filter cartridge 105 is rotated by the rotating component 104, which drives the filter bag 106 inside the filter cartridge 105 to rotate. During the rotation, the waterborne polyurethane passes through the filter bag 106 and the filter cartridge 105 during centrifugation and is then discharged through the water outlet component 107 on the housing 101. Particulate impurities in the waterborne polyurethane are isolated by the filter belt during centrifugal filtration. The filter bag 106 is detachably connected to the filter cartridge 105 and can be removed and replaced or cleaned periodically. This solves the problem of low processing efficiency in existing devices that filter by squeezing and cannot filter while feeding.
