Description

Technical Field

[0001] This utility model relates to a filtration device, specifically a multi-stage filtration device for epoxy resin production. Background Technology

[0002] Epoxy adhesives, due to their excellent adhesion, chemical resistance, and mechanical properties, are widely used in electronics, electrical engineering, construction, aerospace, and other fields. In the production process of epoxy adhesives, the filtration process is a crucial step in ensuring their purity and product quality. However, existing filtration devices mostly use single-stage filters or multi-layer filters with fixed structures, which have the following shortcomings:

[0003] First, single-stage filters must simultaneously perform the dual functions of trapping large particles and achieving high-precision filtration, making them extremely prone to clogging. Filter clogging not only reduces filtration efficiency and increases energy consumption, but also frequently causes production downtime, resulting in high maintenance costs and shortened filter lifespan.

[0004] Secondly, even if some equipment adopts a multi-layer filtration structure, the fixed connection method between each filter screen and the inconvenience of disassembly and assembly often lead to the need to completely disassemble the equipment when replacing, cleaning and repairing the filter screen, which is time-consuming and labor-intensive and seriously affects the continuity of production.

[0005] Furthermore, single-stage or inflexible multi-stage filtration methods make it difficult to simultaneously ensure filtration efficiency and accuracy when handling high impurity loads, which may result in residual minute impurities in the epoxy resin finished product, affecting the product's quality stability and performance.

[0006] Therefore, there is an urgent need to provide an epoxy resin production filtration device with a reasonable structure, easy layer-by-layer disassembly and maintenance, and capable of multi-stage filtration, in order to solve the above-mentioned technical problems. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a multi-stage filtration device for epoxy resin production, so as to solve the problems existing in the background art.

[0008] This utility model of a multi-stage filtration device for epoxy resin production is achieved through the following technical solution, including a lower device base, a first filter base, a second filter base, and a cover plate.

[0009] A first sealing seat is provided below the first filter seat, and a second sealing seat is provided below the second filter seat;

[0010] The first filter seat is disposed above the lower seat of the device via a first sealing seat, and the second filter seat is disposed above the first filter seat via a second sealing seat; the cover plate covers the second filter seat and is provided with a feed inlet on the cover plate.

[0011] As a preferred technical solution, a first electric telescopic rod is provided on both sides of the lower base of the device, and the output shaft of the first electric telescopic rod is connected to the first sealing seat of the first filter seat, thereby realizing the opening and closing of the first filter seat and the lower base of the device.

[0012] As a preferred technical solution, a second electric telescopic rod is provided on both sides of the first sealing seat, and the output shaft of the second electric telescopic rod is connected to the second sealing seat of the second filter seat, thereby realizing the opening and closing of the second filter seat and the first sealing seat.

[0013] As a preferred technical solution, a third electric telescopic rod is provided on both sides of the second sealing seat, and the output shaft of the third electric telescopic rod is connected to the cover plate, so that the cover plate can be opened and closed by the third electric telescopic rod.

[0014] As a preferred technical solution, a fine filter screen is provided on the first filter seat, and a coarse filter screen is provided on the second filter seat; the epoxy resin enters through the feed port of the cover plate and undergoes multi-stage filtration through the coarse and fine filter screens.

[0015] As a preferred technical solution, a discharge port is provided below the lower part of the device, and a discharge valve is provided at the discharge port for discharging the epoxy resin after filtration.

[0016] As a preferred technical solution, a control panel is also included, which is connected to control the first electric telescopic rod, the second electric telescopic rod, the third electric telescopic rod, and the discharge valve.

[0017] The beneficial effects of this utility model are:

[0018] This invention uses electric telescopic rods to connect and drive each filter unit, enabling each level of the device to open and close independently and quickly. This significantly improves the convenience of cleaning, replacing, and maintaining the filter screen, avoids overall disassembly, greatly improves maintenance efficiency, reduces equipment downtime, and ensures the continuity and stability of production.

[0019] This invention incorporates coarse and fine filters, allowing materials to undergo coarse and fine filtration sequentially from top to bottom. This effectively distributes the filtration load, with the coarse filter effectively intercepting larger particles and protecting the fine filter from clogging, while the fine filter ensures the final filtration accuracy. This multi-stage filtration structure not only significantly improves filtration effect and efficiency and reduces the risk of clogging of single-layer filters, but also extends the service life of the filters, ensuring that the epoxy resin product has higher purity and quality stability.

[0020] In addition, the electric telescopic rod and discharge valve are centrally controlled through the control panel, realizing the automated operation of the device and further improving production efficiency and operational safety. Attached Figure Description

Detailed Implementation

[0028] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0029] like Figures 1 to 4 As shown, the present invention relates to a multi-stage filtration device for epoxy resin production, comprising a lower device 1, a first filter seat 2, a second filter seat 3, and a cover plate 4, the overall structure being arranged sequentially from bottom to top.

[0030] The lower base 1 is the foundation of the entire device. It is made of metal and has high structural strength and stability. It supports the filter seats and related components above and ensures that the entire filtration device does not shift or vibrate during operation.

[0031] In this embodiment, a first sealing seat 9 is provided below the first filter seat 2, and a second sealing seat 11 is provided below the second filter seat 3.

[0032] The first filter seat 2 is detachably mounted above the lower seat 1 of the device via the first sealing seat 9, while the second filter seat 3 is detachably mounted above the first filter seat 2 via the second sealing seat 11. Both the first sealing seat 9 and the second sealing seat 11 employ an elastic sealing ring structure, enabling a reliable sealing fit between the filter seats to prevent material leakage. Simultaneously, it facilitates the separation and reassembly of the components, meeting the dual requirements of sealing and maintainability during device operation.

[0033] On both sides of the lower base 1 of the device, a first electric telescopic rod 8 is respectively provided, and the output shaft of the first electric telescopic rod 8 is fixedly connected to the first sealing seat 9 of the first filter seat 2. The first electric telescopic rod 8 adopts an electric drive method, and the first filter seat 2 can be raised and lowered relative to the lower base 1 of the device through electric telescopic action;

[0034] When it is necessary to clean, repair or replace the fine filter screen inside the first filter seat 2, the first electric telescopic rod 8 can be operated through the control panel to raise the first filter seat 2 to a preset height, leaving enough space for the operator to perform maintenance. When the device is working normally, the first filter seat 2 can be lowered to a position that fits tightly with the lower seat 1 of the device to ensure the sealing effect and normal operation of the device.

[0035] On both sides of the first sealing seat 9, a second electric telescopic rod 10 is symmetrically arranged, and the output shaft of the second electric telescopic rod 10 is fixedly connected to the second sealing seat 11 of the second filter seat 3. Through the electric drive of the second electric telescopic rod 10, the second filter seat 3 can also be raised and lowered relative to the first sealing seat 9. Therefore, when it is necessary to clean, disassemble, or replace the coarse filter screen inside the second filter seat 3, the second electric telescopic rod 10 can be driven through the control panel to raise the second filter seat 3 to a position that is easy to operate, improving the maintenance efficiency of the device and reducing downtime caused by overall disassembly.

[0036] A third electric telescopic rod 12 is symmetrically arranged on both sides of the second sealing seat 11, and the output shaft of the third electric telescopic rod 12 is fixedly connected to the cover plate 4. Driven by the third electric telescopic rod 12, the cover plate 4 can be raised or lowered relative to the second filter seat 3. Before operation, the cover plate 4 can be lifted by the third electric telescopic rod 12, exposing the feed inlet 7 above the second filter seat 3, facilitating the feeding of epoxy resin or the material to be filtered into the device. After feeding, the cover plate 4 is lowered by controlling the third electric telescopic rod 12 via the control panel, sealing the top of the second filter seat 3 to prevent material leakage during filtration and effectively preventing external impurities from entering the device, ensuring the cleanliness of the production environment.

[0037] In order to achieve a multi-stage filtration effect for epoxy resin, in this embodiment, a fine filter screen 13 is provided inside the first filter seat 2. The fine filter screen 13 is made of high-precision stainless steel wire mesh or other precision filter materials resistant to chemical corrosion. It has a small pore size and is mainly used to intercept tiny particles or impurities to ensure the final purity of the epoxy resin.

[0038] The second filter seat 3 is equipped with a coarse filter 14. The coarse filter 14 is made of stainless steel mesh with relatively large pores or other durable materials. Its main function is to perform preliminary filtration of the epoxy resin entering the device, intercept larger particulate impurities, and prevent the fine filter 13 from clogging prematurely.

[0039] After the epoxy resin enters the device through the feed port 7 on the cover plate 4, it first undergoes primary filtration through the coarse filter screen 14. The coarse filter screen 14 traps larger impurity particles, allowing the preliminarily purified material to enter the first filter seat 2 and undergo more refined filtration through the fine filter screen 13, achieving a multi-stage filtration effect of progressive purification from coarse to fine.

[0040] This multi-stage filtration structure not only effectively distributes the load on each filtration layer, but also greatly reduces the risk of clogging of the fine filter screen, thereby extending the service life of the filter screen and improving filtration efficiency and product quality.

[0041] In order to facilitate the discharge of epoxy resin after filtration, in this embodiment, a discharge port 15 is provided below the lower seat 1 of the device, and a discharge valve is installed at the discharge port 15.

[0042] The discharge valve is controlled by electric or manual means. By opening and closing, it can achieve quantitative discharge of filtered epoxy resin, which not only ensures the cleanliness and smoothness of the discharge process, but also facilitates the connection of subsequent production processes.

[0043] In terms of operation and control, in order to improve the intelligence and convenience of the entire device, this utility model also includes a control panel. The control panel integrates multiple control circuits and display modules, and controls the opening and closing operations of the first electric telescopic rod 8, the second electric telescopic rod 10, the third electric telescopic rod 12 and the discharge valve through electrical connections.

[0044] Operators can precisely control the movement of each component through the touch buttons or knobs on the control panel, realizing the automatic lifting and lowering of each filter seat and cover plate, as well as the precise opening and closing of the discharge valve, thereby greatly improving the ease of operation and the level of intelligence of the device operation, and reducing the intensity of manual labor.

[0045] The multi-stage filtration device for epoxy resin production described in this utility model uses stacked coarse and fine filter screens 14 and 13 to perform multi-stage filtration of epoxy resin. Each filter seat and cover is driven by an electric telescopic rod to achieve rapid lifting and separation, which significantly improves the device's maintenance convenience, filtration efficiency, and product purity. It effectively solves the problems of easy clogging of filter screens, difficult maintenance, and difficulty in ensuring filtration accuracy in the prior art, and is suitable for the high-purity and high-efficiency filtration requirements in epoxy resin production.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
