Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of filtering equipment, in particular to a filtering device for adhesive production. BACKGROUND

[0002] In the early days, simple filter screen filtering was a common means. This method can only intercept larger obvious impurity particles, and has little effect on fine impurities such as small colloidal aggregates generated in the production process, dust particles carried by raw materials, and small insoluble substances left over by chemical reactions. These fine impurities that have not been effectively filtered mixed into the finished adhesive can significantly reduce the bonding performance and stability of the adhesive. In application scenarios such as electronic component precision bonding and high-end furniture manufacturing that are sensitive to adhesive quality, product quality problems are extremely likely to occur, and subsequent sedimentation filtration method uses gravity to make impurities naturally settle, but it takes a very long time, greatly slowing down the production rhythm and unable to adapt to the high-efficiency production needs of modern industrialization. Moreover, during the sedimentation process, some impurities with high viscosity are easy to re-mix with the main body of the adhesive, which also affects the quality of the final product.

[0028] The circulating filtering assembly 3 further comprises a vacuum cavity shell 321, a scraper 322, a guide plate 323 and a suction groove 324, the vacuum cavity shell 321 is fixedly installed at the bottom of the circulating pump body 306, the bottom of the vacuum cavity shell 321 is fixedly installed with the scraper 322, one side of the scraper 322 is fixedly connected with the guide plate 323, and the suction groove 324 is arranged at the connection position of the scraper 322 and the guide plate 323.

[0029] The second partition cavity 305 comprises two cleaning grooves which are symmetrically arranged with the axis of the cleaning cavity shell 303 as the center, and the first partition cavity 304 comprises two liquid inlet holes which are symmetrically arranged with the axis of the cleaning cavity shell 303 as the center.

[0030] The first filtering hole 314 is in communication with the first partition cavity 304, the second partition cavity 305 is in communication with the second filtering hole 315, the worm wheel 312 is movably installed between the cleaning cavity shell 303 and the shunt cavity shell 316 through the rotating shaft, the top and the bottom of the worm wheel 312 are provided with the sealing rings 313, and the worm wheel 312 is movably connected with the cleaning cavity shell 303 and the shunt cavity shell 316 through the sealing rings 313.

[0031] One side of the circulating pump body 306 is in communication with the second partition cavity 305, and the other side of the circulating pump body 306 is in communication with the shunt pipe 308.

[0032] It is further explained that the circulating filtering assembly 3 is described in detail as follows:

[0033] The cooperation of the liquid inlet funnel 301, the liquid inlet groove 302 and the cleaning cavity shell 303: the liquid inlet funnel 301 is located at the top of the top plate 2, and the large opening design facilitates the reception of the adhesive production raw material liquid from the outside, can effectively collect the liquid under different conveying modes, and avoid the liquid splashing and the like. The liquid inlet groove 302 at the bottom plays a transition and guiding role, and the liquid flowing from the liquid inlet funnel 301 is more uniformly and smoothly introduced into the inside of the cleaning cavity shell 303, which lays a foundation for subsequent partition filtering and the like in the cleaning cavity shell 303. The cleaning cavity shell 303 is a key component for containing and limiting the liquid flow space, and through the first partition cavity 304 and the second partition cavity 305 penetratingly arranged at the top, the flowing liquid is preliminarily distributed according to certain paths and rules, and the subsequent more delicate filtering link is prepared.

[0034] The functions and features of the first partition cavity 304 and the second partition cavity 305: The first partition cavity 304 comprises two liquid inlet holes symmetrically arranged around the axis of the cleaning cavity shell 303. The symmetrical design can ensure that the liquid uniformly enters the area where the first filter hole 314 is located, avoiding the situation that the local liquid flow is too large or too small, so that the filtering process is more stable and efficient. The second partition cavity 305 also adopts a symmetrical design of two cleaning grooves, which is in communication with the circulating pump body 306. Under the action of the circulating pump, the liquid can be temporarily stored and mixed in this cavity, and through the communication with the second filter hole 315, a reasonable liquid flow path is provided for the subsequent re-filtering process. The two partition cavities work together to realize the preliminary regulation of the liquid flow direction and flow.

[0035] Working principle of the circulating pump body 306 and its role in the entire assembly: The circulating pump body 306 is the power core of the entire circulating filter assembly 3. It is in communication with the second partition cavity 305 on one side, which can extract the liquid in the second partition cavity 305, and in communication with the shunt pipe 308 on the other side, thereby delivering the extracted liquid to the shunt pipe 308 for the next shunt operation. Through continuous operation, the circulating pump body 306 makes the liquid continuously circulate in the entire filter device, ensuring the continuity of the filtering process and overcoming the problem of stagnation that may occur due to resistance and other factors during the flow of the liquid. It is a key power component that maintains the orderly progress of the entire filtering process.

[0036] The relationship and functions of the positioning seat 307, the shunt pipe 308, and the bracket 309: The positioning seat 307 is fixedly installed on one side of the circulating pump body 306. Its main function is to accurately fix and communicate the shunt pipe 308, ensuring that the liquid output by the circulating pump body 306 can accurately enter the shunt pipe 308, avoiding liquid leakage or incorrect flow due to unstable connection or positional deviation. The bracket 309 is connected to the bottom of the positioning seat 307, providing stable support for the positioning seat 307. It is also fixedly installed on the inner wall of the shell body 1, so that the entire circulating pump body 306 and the components connected thereto can be stably installed inside the shell, ensuring that the device does not shake during operation and affecting normal work. At the same time, the bracket 309 also provides an installation position for the servo motor 310, realizing the integrated installation and cooperative work of multiple components.

[0037] Transmission mechanism of the servo motor 310, the worm 311, and the worm gear 312 and its influence on filtering:

[0038] The servo motor 310 is installed on one side of the support 309 as a power source, and the output end of the fixedly installed worm 311 rotates with the rotation of the motor. The worm 311 is in meshing transmission with the worm gear 312, and this transmission mode has a large transmission ratio, which can convert the high-speed rotation of the servo motor 310 into relatively slow but large-torque rotation of the worm gear 312. By controlling the rotation speed, rotation direction and other parameters of the servo motor 310, the rotation of the worm gear 312 can be accurately controlled. The first filter hole 314 and the second filter hole 315 are formed in the worm gear 312, and the rotation of the worm gear 312 can change the communication state of the filter holes and the corresponding separation chambers, realize selective filtration of impurities with different particle sizes and properties, and flexibly adjust the filtration mode according to the specific situation of the adhesive in actual production, greatly improving the adaptability and filtration effect of the filtration device.

[0039] The importance of the sealing ring 313 in the connection of the worm gear 312 and other components: the worm gear 312 is movably connected with the cleaning cavity shell 303 and the shunt cavity shell 316 through the sealing ring 313, and the sealing ring 313 plays a crucial sealing role here. During the filtration process, the liquid flows between the chambers according to a specific path, and if there is no good sealing, the liquid may leak from the connection between the worm gear 312 and the shell, which not only reduces the filtration efficiency, but also affects the pressure, liquid level and other parameters inside the whole device, thereby destroying the stability of the filtration process. The sealing ring 313 can effectively prevent such leakage, ensure that the liquid flows in an orderly manner from the first separation chamber 304 through the first filter hole 314, the second separation chamber 305 through the second filter hole 315, etc., and ensure the accuracy and reliability of the filtration operation.

[0040] Liquid shunting and collecting action of the shunt cavity shell 316, the liquid outlet branch pipe 317, the collection cavity shell 318, the impurity collection pipe 319 and the impurity collection tank 320: the shunt cavity shell 316 is located at the bottom of the worm gear 312, and the bottom is communicated with the liquid outlet branch pipe 317 and the impurity collection pipe 319. The liquid filtered by the worm gear 312 performs a key shunting operation here. The filtered clear liquid is transported to the collection cavity shell 318 through the liquid outlet branch pipe 317 for collection, realizing the collection and temporary storage of the clear liquid, which is convenient for subsequent unified use for the subsequent process of adhesive production. The impurities flow into the impurity collection tank 320 along the impurity collection pipe 319, and the impurity collection tank 320 can be cleaned regularly. This centralized collection of impurities avoids the accumulation of impurities in the device, prevents the impurities from affecting the performance of the filtration device, and facilitates the subsequent treatment and analysis of the impurities, so as to further optimize the production process.

[0041] The mechanism of the vacuum cavity shell 321, the scraper 322, the guide plate 323 and the suction groove 324 in impurity cleaning: the vacuum cavity shell 321 is fixedly installed at the bottom of the circulating pump body 306, and a special environment created thereby can be a negative pressure environment and the like, which can help to improve the effect of impurity cleaning. The scraper 322 is installed at the bottom of the vacuum cavity shell 321, and in the process of liquid flowing, the scraper 322 can scrape off the impurities attached to the surface of the related components, so as to prevent the impurities from being attached for a long time to affect the filtration and liquid flowing. The guide plate 323 is connected with one side of the scraper 322, and can guide the scraped impurities to a specific direction. The suction groove 324 is arranged at the connection between the scraper 322 and the guide plate 323, and in combination with the special environment created by the vacuum cavity shell 321, the impurities can be more efficiently collected through the adsorption effect, so as to further enhance the cleaning capacity of the device for the impurities, keep the components inside the device clean, and ensure that the filtration device can be stably operated for a long time and continuously exert good filtration performance.

[0042] The working principle of the above embodiment is as follows:

[0043] 1. Liquid entering stage

[0044] The adhesive production raw material liquid enters the device through the liquid inlet funnel 301. The wide-mouth design of the liquid inlet funnel 301 facilitates the reception of the liquid, and the liquid flows smoothly into the cleaning cavity shell 303 along the liquid inlet groove 302 at the bottom.

[0045] In the cleaning cavity shell 303, the liquid enters the first partition cavity 304 and the second partition cavity 305 respectively. The two liquid inlet holes of the first partition cavity 304 uniformly distribute the liquid, so as to prepare for the subsequent filtration link; and the two cleaning grooves of the second partition cavity 305 start to participate in the liquid circulation under the action of the circulating pump body 306.

[0046] 2. Liquid circulation and power transmission stage

[0047] The circulating pump body 306 starts to work as a power source, which draws out the liquid in the second partition cavity 305, and then transmits the liquid to the shunt pipe 308 through the pipeline connected with one side of the circulating pump body 306.

[0048] At the same time, the positioning seat 307 ensures the stable connection of the shunt pipe 308, and the servo motor 310 on the support 309 starts to work to output power to drive the worm 311 to rotate.

[0049] The worm 311 drives the worm gear 312 engaged therewith to rotate, and the worm gear 312 is movably installed between the cleaning cavity shell 303 and the shunt cavity shell 316 through a rotating shaft, so that the rotating movement of the worm gear 312 starts to filter the liquid.

[0050] 3. Filtration stage

[0051] When the worm wheel 312 rotates, the first filter hole 314 at the top of the worm wheel 312 is in communication with the first partition cavity 304, and the second filter hole 315 is in communication with the second partition cavity 305. Under the action of the pressure difference and the circulating pump, the liquid is filtered through the first filter hole 314 and the second filter hole 315, respectively.

[0052] The sealing ring 313 plays a sealing role in the movable connection of the worm wheel 312 with the cleaning cavity shell 303 and the shunt cavity shell 316, ensuring that the liquid flows along the predetermined path, i.e., from the partition cavity through the filter hole into the shunt cavity shell 316, preventing liquid leakage and cross-flow, and ensuring the accuracy of the filtration.

[0053] 4. Liquid shunting and collecting stage

[0054] In the shunt cavity shell 316, the filtered liquid is shunted. The clear filtrate flows into the collection cavity shell 318 through the bottom-communicating liquid outlet branch pipe 317 for collection, which is convenient for subsequent use in adhesive production.

[0055] The part of the liquid containing impurities flows to the impurity collection tank 320 through the impurity collection pipe 319, realizing the separation and centralized collection of impurities, which is convenient for regular cleaning and treatment of impurities.

[0056] 5. Impurity cleaning stage

[0057] The scraper 322 at the bottom of the vacuum cavity shell 321 scrapes off the impurities attached to the surface of the related components during the operation of the device.

[0058] The scraped impurities are collected through the suction slot 324 at the connection between the scraper 322 and the guide plate 323 under the guidance of the guide plate 323. The negative pressure environment created by the vacuum cavity shell 321 helps to enhance the adsorption and collection effect of the impurities, maintain the cleanliness of the inside of the device, and prevent the residual impurities from having adverse effects on the filtration process.

[0059] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made in terms of structure, shape, and principle based on the present application should be covered within the protection scope of the present application.
