Description

Technical Field

[0001] This utility model relates to the field of adhesive filtration technology, and in particular to an adhesive filter. Background Technology

[0002] Adhesive solutions are high-viscosity liquids widely used in industrial production, chemical processing, and electronics manufacturing. During production and storage, they often become contaminated with solid impurities, particles, or lumps, affecting the stability of subsequent processes and the quality of the finished product. To ensure the purity and performance of the adhesive solution, filtration is usually required. Commonly used adhesive filtration equipment includes mesh filters, plate and frame filters, and centrifuges. While these devices can achieve a certain degree of solid-liquid separation, they are prone to problems such as low filtration efficiency, frequent clogging, and difficulty in cleaning and maintenance when handling high-viscosity adhesive solutions.

[0003] Existing adhesive filtration equipment generally suffers from the following shortcomings: First, the feeding structure is relatively simple, leading to unstable flow of the adhesive upon entering the separation chamber and resulting in low centrifugal separation efficiency. Second, most filtration units are single-stage structures, limiting their effectiveness in removing fine impurities. Third, the discharge and cleaning processes of some equipment rely on manual operation, resulting in low automation and impacting production continuity. Therefore, there is an urgent need for an adhesive filter with a reasonable structure, high filtration accuracy, high separation efficiency, and easy maintenance to improve adhesive treatment quality and production efficiency.

[0004] Therefore, a glue filter was proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a glue filter.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a glue filter, comprising a filter body, wherein the filter body comprises, in sequence, a centrifuge tank, a storage tank and a base. The centrifuge tank has a feed inlet at its top, and the inner wall of the feed inlet has a spiral guide groove, the end of which extends to the inner wall of the centrifuge hopper. A ring-shaped electric guide rail is fixed to the top of the inner wall of the centrifuge tank. The centrifuge hopper is rotatably connected to the bottom of the centrifuge tank through a bearing and is driven to rotate by the ring-shaped electric guide rail. The centrifuge hopper is funnel-shaped, and the inner wall of the centrifuge hopper is provided with an anti-stick coating. The storage tank is connected to the centrifuge tank through a flange, and a multi-stage filtration structure is provided at the connection. The base is connected to the storage tank, and the bottom of the base is provided with a discharge port.

[0007] As a preferred embodiment of this invention, the spiral guide groove is used to tangentially guide the adhesive entering the centrifugal hopper to improve centrifugal separation efficiency.

[0008] As a preferred embodiment of this utility model, the inner side of the annular electric guide rail is provided with a toothed transmission belt, and the outer wall of the centrifugal bucket is provided with a gear ring that meshes with the toothed transmission belt.

[0009] As a preferred technical solution of this utility model, the multi-stage filtration structure includes: an upper layer of stainless steel wire mesh and a lower layer of polypropylene meltblown filter element.

[0010] As a preferred technical solution of this utility model, the base is provided with a discharge pump, which is connected to the discharge port for discharging the adhesive liquid.

[0011] As a preferred embodiment of this utility model, the storage tank is equipped with a liquid level sensor, and the outer wall of the storage tank is equipped with a constant temperature water jacket, which is connected to a heating device for constant temperature control of the adhesive liquid in the storage tank.

[0012] The beneficial effects of this utility model are reflected in: This invention utilizes a spiral guide channel at the centrifuge tank inlet to create tangential flow of the incoming adhesive solution. Combined with a centrifuge bucket driven by a ring-shaped electric guide rail, this achieves highly efficient centrifugal separation, significantly improving solid-liquid separation efficiency and reducing impurity residue. The anti-stick coating on the inner wall of the centrifuge bucket effectively prevents adhesive adhesion, facilitating cleaning and maintenance. A multi-stage filtration structure between the storage tank and the centrifuge tank enables progressively fine filtration of the adhesive solution, ensuring the purity of the output liquid. An integrated discharge pump structure in the base stably delivers the purified adhesive solution to subsequent processes, improving production continuity. The overall structure is compact, highly automated, and has excellent sealing performance, significantly improving the efficiency, quality, and stability of adhesive solution filtration while reducing manual intervention and maintenance costs. It is suitable for various industrial production scenarios. Attached Figure Description

[0015] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. 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 scope of protection of the present utility model.

[0016] Please see Figure 1-2 This utility model discloses a glue filter, including a filter body 1, which includes a centrifuge tank 2, a storage tank 5 and a base 6 in sequence.

[0017] The centrifuge tank 2 is provided with a feed inlet 201 at the top. The inner wall of the feed inlet 201 is machined with a spiral guide groove. The end of the spiral guide groove extends to the inner wall of the centrifuge bucket 203, which is used to tangentially guide the incoming adhesive into the centrifuge bucket 203, so that the adhesive can obtain an initial rotation speed when it enters, thereby improving the efficiency of subsequent centrifugal separation.

[0018] A ring-shaped electric guide rail 202 is fixed to the top of the inner wall of the centrifuge tank 2. A toothed drive belt is provided on the inner side of the ring-shaped electric guide rail 202. A gear ring that meshes with the toothed drive belt is fixed to the outer wall of the centrifuge bucket 203. The ring-shaped electric guide rail 202 is connected to an external control unit, and the speed of the centrifuge bucket 203 is controlled by adjusting the speed of the drive motor. The centrifuge bucket 203 is rotatably connected to the bottom of the centrifuge tank 2 via a bearing 204. The bucket is funnel-shaped, with a larger top area than bottom area, and its inner wall is coated with a polytetrafluoroethylene (PTFE) anti-stick coating to prevent adhesive residue from adhering and facilitate cleaning.

[0019] Storage tank 5 is connected to the bottom flange of centrifuge tank 2 via flange 3, and a sealing ring is provided at the flange connection to prevent leakage. A multi-stage filtration structure 4 is installed at the connection between storage tank 5 and centrifuge tank 2. This multi-stage filtration structure 4 includes an upper stainless steel wire mesh and a lower polypropylene melt-blown filter element. The stainless steel wire mesh is used for preliminary filtration of large particulate impurities, and the polypropylene melt-blown filter element is used to further remove fine particles to ensure the purity of the adhesive solution.

[0020] The storage tank 5 is equipped with a liquid level sensor inside to monitor the level of the adhesive in the storage tank 5 in real time. The outer wall of the storage tank 5 is equipped with a thermostatic water jacket 501, which is connected to an external heating device. The thermostatic water jacket 501 achieves constant temperature heating by circulating hot water or heating medium, and works with the temperature control system to maintain the temperature of the adhesive within the set range to prevent the performance of the adhesive from deteriorating due to temperature changes.

[0021] The base 6 is installed at the bottom of the storage tank 5 and serves to support the filter body 1. The bottom of the base 6 is provided with a discharge port 7, which is connected to the discharge pump inside the base 6 for outputting the filtered adhesive to subsequent storage or production processes.

[0022] With the above structural design, in actual use, the adhesive enters through the inlet 201 and is tangentially guided into the centrifugal hopper 203 via the spiral guide channel. Driven by the annular electric guide rail 202, the centrifugal hopper 203 rotates at high speed, throwing impurities in the adhesive against the inner wall of the hopper 203, which then slides down to the bottom and is discharged. The adhesive then enters the storage tank 5 through the bottom outlet channel, where it is further purified through the multi-stage filtration structure 4. The purified adhesive is stored in the storage tank 5 and then pumped out through the outlet 7 by the discharge pump for external use.
