Description

Technical Field

[0001] This utility model belongs to the field of water-based emulsion coating adhesive technology, and in particular relates to a filter device for unloading water-based emulsion coating adhesive. Background Technology

[0002] High-value-added acrylic adhesives are a type of water-based emulsion coating adhesive. They refer to acrylic-based adhesives that possess high performance, special functions, or high application value through technological improvements, formulation optimization, or functional design. Some high-value-added acrylic adhesives contain methyl methacrylate (MMA), which easily emits a pungent odor.

[0003] In the existing technology, high value-added acrylic adhesives require filtration using filter bags during production and processing. However, the installation and removal of filter bags is time-consuming, resulting in long downtime of the entire equipment and affecting processing efficiency. Furthermore, some high value-added acrylic adhesives have a pungent odor, which can easily affect the surrounding working environment when they are replaced.

[0004] Therefore, we propose a filtration device for unloading water-based emulsion coated adhesives. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the time-consuming installation and disassembly of filter bags, which leads to long downtime of the overall equipment and affects processing efficiency, and the fact that some high-value-added acrylic adhesives have a pungent odor that can easily affect the surrounding working environment when replaced. Therefore, this invention proposes a water-based emulsion coated adhesive unloading filter device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A filtration device for unloading water-based emulsion coated adhesive includes:

[0008] The box body has a door hinged to one side. The surface and bottom of the box body are respectively fixedly connected by an inlet pipe and an outlet pipe. A control valve is fixedly installed on the outer wall of the inlet pipe. A connecting sleeve is threaded to the bottom of the inlet pipe. A connecting pipe is installed between the connecting sleeve and the outlet pipe. A positioning ring is fixedly installed on the inner wall of the connecting pipe. Two inserts are fixedly installed on the outer wall of the connecting pipe.

[0009] It also includes an installation ring placed inside the connecting pipe. The outer wall of the installation ring has a third connecting groove, which cooperates with the positioning ring. A filter bag is fixed at the bottom of the installation ring.

[0010] An adjustment mechanism, located inside the housing, is used to adjust the position of the connecting pipe;

[0011] An air extraction mechanism is provided on the surface of the housing and is used to extract gas from the housing.

[0012] In one possible design, the adjustment mechanism includes an inverted U-shaped guide rail, which is fixed to the inner wall of one side of the housing. A sliding plate is slidably connected to one side of the guide rail. Two through holes are opened through the surface of the sliding plate. A connecting pipe passes through the through holes. Slots are opened on both sides of the through holes. The slots and plugs are used together.

[0013] In one possible design, the air extraction mechanism includes a fan fixed to the surface of the housing, with one end of the fan inlet connected to an air inlet pipe, the other end of the air inlet pipe passing through the surface of the housing, and the fan outlet connected to an exhaust pipe.

[0014] In one possible design, a mounting bracket is fixed to the top inner wall of the housing, and a filter box is inserted into the mounting bracket. The filter box is located below the air inlet pipe and is filled with activated carbon.

[0015] In one possible design, the bottom of the connecting sleeve is provided with a first connecting groove, the top of the connecting tube abuts against the top inner wall of the first connecting groove, and the bottom of the connecting tube is provided with a second connecting groove, the top of the discharge tube abuts against the top inner wall of the second connecting groove.

[0016] In one possible design, the inner wall of the connecting sleeve, the inner wall of the first connecting groove, and the inner wall of the second connecting groove are all provided with sealing grooves, and sealing rings are fixedly embedded in the sealing grooves.

[0017] In one possible design, an adjusting ring is fixed to the outer wall of the connecting sleeve, a collection tray is placed on the bottom inner wall of the box, and a clearance opening is provided on one side of the collection tray.

[0018] In this application, during filtration, the material enters the connecting pipe from the feed pipe and is discharged from the discharge pipe after being filtered by the filter bag.

[0019] When replacing the filter bag, open the box door, place the collection tray on the bottom inner wall of the box, place the filter bag to be replaced into the clean connecting pipe, place the installation ring on the positioning ring so that the positioning ring aligns with the third connecting groove, then place the clean connecting pipe into the through hole of the slide plate so that the insert block enters the slot, then adjust the control valve to close the feed pipe, start the fan to extract the gas inside the box, so that the gas is discharged to another location through the filter box, the air inlet pipe and the exhaust pipe, then use the adjusting ring to rotate the connecting sleeve so that the connecting sleeve disengages from the connecting pipe, then move the slide plate to slide along the direction of the guide rail, so that the slide plate rises, moves horizontally and downwards. The connecting pipe is lowered to quickly replace it. Then, the adjusting ring is rotated in the opposite direction to lower the connecting sleeve and connect it with the new connecting pipe, pressing it tightly. At the same time, the connecting sleeve presses against the installation ring to prevent the filter bag from shaking or shifting. This allows the top of the connecting pipe to enter the first connecting groove and the top of the discharge pipe to enter the second connecting groove. Then, the control valve is reopened to facilitate material flow and filtration. The replaced connecting pipe and filter bag are then stored in a sealed bag, along with the collection tray. The box door is then closed, and the stored connecting pipe, filter bag, and collection tray are transferred elsewhere for cleaning or replacement, ready for the next use.

[0020] Beneficial effects: The filter device for unloading water-based emulsion coating adhesive described in this utility model, through the setting of multiple structures such as sliding plate, insert block and connecting pipe, can quickly replace filter bags, reduce equipment downtime and improve processing efficiency;

[0021] In this utility model, the filter device for unloading water-based emulsion film adhesive, through the arrangement of multiple structures such as a fan, mounting frame and filter box, can remove odorous gas from the box during filter bag replacement, thereby reducing the impact on the surrounding working environment.

[0022] This invention allows for quick replacement of filter bags, reducing equipment downtime and improving processing efficiency. It also allows for the removal of odorous gases from the chamber during filter bag replacement, minimizing the impact on the surrounding working environment. Attached Figure Description
