Description

Technical Field

[0001] The utility model belongs to the field of filtering equipment, and particularly relates to a filtering device with a layered filtering structure. Background Art

[0002] The pharmaceutical water filtering device is used to filter and purify the water used in the pharmaceutical process. The current pharmaceutical water filtering device has many defects without a layered filtering structure. Due to the lack of layering, it is impossible to perform grading treatment on impurities with different particle sizes and properties, resulting in a large amount of impurities remaining in the filtered water and the water quality purity being difficult to reach high standards. This is because the single filtering mode cannot accurately classify and intercept the impurities in the water. For this situation, the conventional solution is to increase the number of filtering processes and increase the filtering pressure. However, increasing the number of filtering processes will increase the floor area of the equipment, raise the investment cost and operating cost, and problems are likely to occur in the connection of multiple processes, affecting the stability and continuity of filtering; increasing the filtering pressure can enhance the filtering effect to a certain extent, but it will accelerate the wear and aging of the equipment, shorten the service life of the equipment, increase the maintenance cost, and may also damage the filtering medium due to excessive pressure, affecting the filtering effect and reliability. The adoption of a layered filtering structure is to accurately intercept in layers according to the characteristics of impurities to achieve efficient filtering. For other filtering structures, such as the meandering filtering structure, the advantage is that it can extend the water flow filtering path and increase the filtering contact area. However, compared with the layered filtering structure, the meandering filtering cannot perform layered treatment according to the characteristics of different impurities, has poor filtering pertinence, and is prone to local accumulation of impurities, reducing the filtering efficiency and increasing the maintenance cost, and cannot accurately and effectively improve the water quality purity like the layered filtering structure. Therefore, a new structure is needed to solve the above technical problems. Summary of the Utility Model

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 to 2 , the present invention provides a technical solution: a filtering device with a layered filtering structure, including: a bracket 100, a filtering box 200, and a filtering component. The filtering box 200 is installed inside the bracket 100. A box cover 220 is clamped on the upper side surface of the filtering box 200. A filtering component is installed inside the filtering box 200. The filtering component includes: an activated carbon filtering element, a first filter screen, a second filter screen, and a third filter screen 270. The activated carbon filtering element is installed inside the filtering box 200. The first filter screen is installed below the activated carbon filtering element. The second filter screen is installed below the first filter screen. The third filter screen 270 is installed below the second filter screen. A discharge pipe is installed on the lower side surface of the filtering box 200. A water outlet pipe 260 is installed through the outer side surface of the filtering box 200. A box door 210 is installed on the outer side surface of the filtering box 200 by means of a damping hinge.

[0019] Please refer to Figure 1 , Figure 2 , as the first embodiment of the present invention: the inner wall inside the bracket 100 is connected to the outer side surface of the filtering box 200. The upper side surface of the filtering box 200 is designed to be open. The lower half of the filtering box 200 is designed in a conical structure. The box cover 220 is hermetically clamped at the opening of the upper side surface of the filtering box 200;

[0020] The activated carbon filtering element includes: a filtering frame 230, activated carbon particles 240, and a hook frame 250. The activated carbon particles 240 are filled inside the filtering frame 230. A hook frame 250 is symmetrically installed on the left and right edges of the upper side surface of the filtering frame 230 respectively. The filtering frame 230 is fixed inside the filtering box 200 through the hook frame 250;

[0021] When in use, the user first opens the lid 220, and then introduces pharmaceutical water into the interior of the filtration tank 200 through the opening on the upper surface of the filtration tank 200. At this time, the pharmaceutical water will first be filtered by the activated carbon particles 240 inside the filter frame 230, and then enter the surface of the first filter screen from the filter frame 230 for filtration, thus achieving a multi-layer stratified filtration effect. After using for a period of time, the user can remove the filter frame 230 from the interior of the filtration tank 200 through the hook rack 250, and then replace the filter particles inside the filter frame 230 to avoid affecting the subsequent filtration effect (the specific replacement time needs to be selected according to the actual situation). Since the activated carbon particles 240 have a rich microporous structure and a large specific surface area, they can effectively adsorb harmful substances such as organic pollutants, odor substances, residual chlorine, and some heavy metal ions in the pharmaceutical water, significantly improving the purification effect of the water. At the same time, not limited to the activated carbon particles 240, the user can fill different types of filter particles (such as zeolite, ion exchange resin, etc.) in the filter frame 230, and can flexibly select according to the specific water quality and filtration requirements of the pharmaceutical water to achieve targeted removal of specific pollutants and improve the accuracy and efficiency of filtration.

[0022] Please refer to Figure 1 、 Figure 2 As the second embodiment of the present utility model: The outer surface of the filter frame 230 abuts against the inner wall of the filtration tank 200. The lower surface of the filter frame 230 is installed with a first filter screen at an inclination of 25 degrees with the left side lower and the right side higher. The lower surface of the first filter screen is installed with a second filter screen at an inclination of 25 degrees with the left side higher and the right side lower. The lower surface of the second filter screen is installed with a third filter screen 270 at an inclination of 25 degrees with the left side lower and the right side higher;

[0023] The pore diameter of the first filter screen is larger than that of the second filter screen, and the pore diameter of the second filter screen is larger than the diameter of the third filter screen 270. Two water outlet pipes 260 are installed through the right side surface of the filtration tank 200, and one water outlet pipe 260 is installed through the left side surface of the filtration tank 200. The water outlet pipe 260 is connected to the high-pressure water supply equipment through a hose;

[0024] A box door 210 is damping-hinged to the right side surface of the filtration tank 200, and two box doors 210 are damping-hinged to the left side surface of the filtration tank 200. A sealing ring is provided at the abutting position between the box door 210 and the filtration tank 200;

[0025] When in use, when the pharmaceutical water enters the surface of the first filter screen through the activated carbon filter element, the first filter screen conducts the first filtration at this time, and then enters the second filter screen through the first filter screen for the second filtration, and then enters the third filter screen 270 through the second filter screen for the third filtration. After the filtration of the third filter screen 270 is completed, the filtered pharmaceutical water will enter the bottom inside the filter box 200, and then be discharged through the discharge pipe for subsequent processing and use. After the first filter screen, the second filter screen, and the third filter screen 270 are used for a period of time, the user can open the corresponding box door 210, and then start the external water supply device to make the water outlet pipe 260 spray water to wash the surfaces of the first filter screen, the second filter screen, and the third filter screen 270, so as to prevent the mesh holes of the first filter screen, the second filter screen, and the third filter screen 270 from being blocked, resulting in a reduction in the filtration effect. Since the first filter screen, the second filter screen, and the third filter screen 270 have different pore sizes, they can sequentially filter out pollutants such as particulate impurities of different sizes, realizing the deep filtration and purification of pharmaceutical water, and significantly improving the purity and cleanliness of the water quality.

[0026] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
