Description

Technical Field

[0001] This utility model relates to the field of water treatment, and in particular to a filtration device for purifying water preparation. Background Technology

[0002] Purified water is mainly used as a solvent for preparing common pharmaceutical preparations or as experimental water. It can also be used as an extraction solvent for medicinal materials used in sterilized preparations such as traditional Chinese medicine injections and eye drops, as well as as water for rinsing equipment used in non-sterile preparations.

[0003] Purified water is generally produced from raw water (drinking water) through processes such as filtration, adsorption, and purification. Raw water contains various impurities during production and transportation, including suspended impurities, colloidal impurities, and microorganisms. Current technologies typically require multiple independent filtration devices or complex processes to filter impurities of different particle sizes. These devices have large footprints, high investment costs, and low filtration efficiency, making it difficult to meet the demands for efficient and precise graded filtration. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a filtration device for purifying water preparation. By combining a multi-layer filter screen (each layer with a different pore size) with a vibrator of a specific frequency, impurities of different particle sizes are efficiently intercepted in the matched filter screen layers, thereby improving the filtration efficiency. At the same time, the overall structure of the device is relatively simple, the footprint is small, and the investment cost is low.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A filtration device for purifying water includes a housing, multiple layers of filter screens, and multiple vibrators. The housing has multiple inlets and outlets. The multiple inlets are evenly distributed on the top of the housing and communicate with the outlets. The multiple layers of filter screens are arranged sequentially from top to bottom inside the housing, and the pore size of the multiple layers of filter screens decreases from top to bottom. Each vibrator is connected to one of the filter screens, and the operating frequency of the multiple vibrators increases as the pore size of the corresponding filter screen decreases.

[0007] Furthermore, the vibration frequency f of the exciter and the aperture d of the filter screen satisfy the following relationship: f = k / d, where k = 1 × 10³ ~ 5 × 10⁻⁶. 4 Hz·μm.

[0008] Furthermore, there are three filters and three vibrators. The pore sizes of the three filters from top to bottom are 200μm, 50μm, and 1μm, respectively, and the vibration frequencies of the vibrators are 50Hz, 100Hz, and 500Hz, respectively.

[0009] Furthermore, the filtration device for preparing purified water also includes a plurality of excitation springs, one end of each excitation spring being connected to the vibrator and the other end being connected to the filter screen.

[0010] Furthermore, the material of the filter screen is selected from one or more of stainless steel, polyester, and ceramic.

[0011] Furthermore, the filtration device for preparing purified water also includes a control system, and the multiple vibrators are all communicatively connected to the control system. The control system can automatically adjust the vibration frequency and amplitude of each layer of the filter screen according to the influent water quality and flow rate.

[0012] Furthermore, the filtration device for purifying water preparation also includes an activated carbon adsorption plate, which is disposed between the last layer of the filter screen and the water outlet.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] 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 some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Figures 1-3 The present invention relates to a filtration device for preparing purified water, comprising a housing 10, a filter screen 20, and a vibrator 30.

[0022] In this embodiment:

[0023] The housing 10 is provided with multiple inlets 11 and outlets 12. The multiple inlets 11 are evenly distributed on the top of the housing 10 and communicate with the outlets 12, which are used to evenly deliver raw water (drinking water) into the housing 10, thereby improving the subsequent filtration accuracy. In other embodiments, only one inlet 11 can be provided on the top of the housing 10, and then a guide plate can be provided between the inlet 11 and the first layer of filter screen 20. By setting up a passage pipe on the guide plate, the raw water (drinking water) can be evenly delivered. This structure is more complex, but the subsequent filtration effect is better.

[0024] The multi-layer filter screens 20 are arranged sequentially from top to bottom inside the housing 10. The pore size of the multi-layer filter screens 20 decreases from top to bottom. The material of the filter screens 20 is selected from one or more of stainless steel, polyester, and ceramic.

[0025] Each vibrator 30 is connected to a filter screen 20. The operating frequency of the multiple vibrators 30 increases as the pore size of the corresponding filter screen 20 decreases. The vibration frequency of each vibration motor can be adjusted according to the pore size of the corresponding filter screen 20 and the characteristics of impurity interception. Specifically, low-frequency vibration energy is concentrated in inertial force, causing large particles to "jump" or "roll" on the filter screen surface, rather than penetrate the filter screen; high-frequency vibration energy is concentrated in Brownian motion enhancement, increasing the diffusion rate of small particles in the liquid. High-frequency vibration causes small particles to "micro-stir" in the micropores of activated carbon, increasing the probability of contact with the adsorbent material. In this embodiment, the vibrator 30 is a vibration motor or an eccentric block. The vibration frequency f of the vibrator 30 and the pore size d of the filter screen 20 satisfy: f = k / d, where k = 1 × 10³ ~ 5 × 10⁻⁶. 4 Hz·μm. There are three filters 20 and three vibrators 30. The pore sizes of the three filters 20 from top to bottom are 200μm, 50μm and 1μm, respectively. The vibration frequencies of the vibrators 30 are 50Hz, 100Hz and 500Hz, respectively.

[0026] Each excitation spring 40 is connected at one end to the vibrator 30 and at the other end to the filter screen 20. The excitation spring 40 converts the power of the vibrator 30 into the stable vibration of the filter screen 20 through elastic deformation, while protecting the equipment from impact damage.

[0027] The control system 50 is communicatively connected to multiple vibrators 30. The control system 50 can automatically adjust the vibration frequency and amplitude of each filter screen 20 according to the water quality and flow rate. For example, when the impurity content of the influent is high, the vibration frequency and amplitude are increased to improve the filtration efficiency; when the influent flow rate is low, the vibration frequency is reduced to save energy.

[0028] The activated carbon adsorption plate 60 is set between the last layer of filter screen 20 and the outlet 12 for deep treatment of effluent, reducing COD (chemical oxygen demand) and BOD (biochemical oxygen demand) and improving water quality.

[0029] The working process for this application is as follows:

[0030] Raw water (drinking water) is evenly distributed onto the first filter screen 20 through multiple inlets 11. The first filter screen 20 vibrates at 50Hz under the action of the corresponding first vibrator 30, intercepting larger particles of impurities. The water passing through the first filter screen 20 continues to the second filter screen 20, which vibrates at 100Hz under the action of the corresponding vibrator 30, intercepting medium-sized particles of impurities. The water passing through the second filter screen 20 continues to the third filter screen 20, which vibrates at 200Hz under the action of the corresponding vibrator 30, intercepting fine particles of impurities. The water filtered through the three filter screens 20 flows out of the device from the outlet 12.

[0031] In this application, by combining a multi-layer filter screen 20 (each layer with a different pore size) with a vibrator 30 of a specific frequency, impurities of different particle sizes are efficiently intercepted in the matched filter screen 20 layers, thereby improving filtration efficiency. At the same time, the overall structure of the device is relatively simple, occupies a small area, and has a low investment cost.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
