Description

Technical Field

[0001] The present invention relates to the field of gas filters, and particularly to a dual - fan three - stage electrolytic gas filter. Background Art

[0002] With the development of technology, 3D printers and laser engraving machines are widely used in various industries. However, during their operation, they often release a large amount of harmful gases, including volatile organic compounds (VOCs), odors, and particulate matter. These pollutants not only affect the working environment but may also pose a hazard to the health of operators. Therefore, it is particularly important to develop an efficient gas filter.

[0003] The existing gas filtration technologies mainly rely on physical interception or adsorption methods to remove particulate matter and some gaseous pollutants in the air. These traditional filters usually intercept pollutants through means such as filter meshes, macromolecular filter cotton, or activated carbon. Although they can achieve a certain degree of purification, their removal effects on some volatile organic compounds (VOCs) and odors are limited. In addition, the existing filters are prone to performance degradation in humid environments. Especially, activated - carbon - based filter materials are likely to become saturated in moisture and lose their adsorption function. At the same time, when traditional filters work in high - humidity or high - pollution environments, the filtration effect may decline, and bacteria, molds, and other microorganisms may even grow, leading to secondary pollution and affecting the long - term operation effect of the equipment. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the present invention provides a dual - fan three - stage electrolytic gas filter, which solves the problems that traditional filters have limited effects in removing volatile organic compounds (VOCs) and odors, are prone to failure in humid environments, and cause secondary pollution.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A dual - fan three - stage electrolytic gas filter, comprising: An upper shell and a lower shell that are interconnected; A cavity one and a cavity four that are independent of each other are arranged inside the upper shell, a cavity two, a cavity three, and a connection cavity are arranged inside the lower shell, and the cavity one, the cavity two, the connection cavity, the cavity three, and the cavity four are connected in sequence; Macromolecular filter cotton, which is located inside one side of the upper shell and is connected to the cavity one; A fan one and a fan two, which are respectively installed in the cavity one and the cavity four; An electrolytic air inlet cylinder and an electrolytic rod are installed on one side of the bottom of the upper shell, and both are located in the cavity two. The electrolytic air inlet cylinder is used to guide the airflow output by the fan one into the cavity two, and water is arranged in the cavity two; An activated carbon air outlet cylinder is installed on the other side of the bottom of the upper shell and is located in Chamber III. The second fan is used to extract the gas in Chamber III along the activated carbon air outlet cylinder to Chamber IV and discharge it.

The partition is located between Chamber I and Chamber IV. The first fan and the second fan are installed on both sides of the top surface of the bottom plate. The electrolytic air inlet cylinder and the activated carbon air outlet cylinder are respectively installed on both sides of the bottom surface of the bottom plate.

[0013] The present invention provides a double-fan three-stage electrolytic gas filter. It has the following beneficial effects: 1. In the present invention, the first fan can transport external gas along Chamber I to the electrolytic air inlet cylinder and discharge it to Chamber II. The second fan can extract the gas in Chamber II to the connection chamber, enter the activated carbon air outlet cylinder along Chamber III, and finally enter Chamber IV and be discharged. Therefore, the air flow can pass through the macromolecular filter cotton, the electrolytic air inlet cylinder, the electrode rod, and the activated carbon air outlet cylinder in sequence, so as to intercept particulate matter, electrolytically decompose, and adsorb harmful gases in the gas, achieving the effect of three-stage filtration, effectively improving the gas purification efficiency, extending the service life of the equipment, and reducing the filter material replacement frequency.

[0014] 2. In the present invention, by installing a reverse osmosis molecular membrane inside the connection chamber, the gas entering Chamber III through the connection chamber can be finely filtered to remove tiny particles, dissolved gases, and harmful substances therein, thereby further improving the purity of the gas.

[0015] 3. The present invention separates the upper shell from the lower shell, so that the electrolytic air inlet cylinder and the activated carbon air outlet cylinder can be removed from the bottom plate, and the reverse osmosis molecular membrane can also be taken out from the connecting cavity, so it can be quickly disassembled and replaced.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the specification 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 creative efforts shall fall within the protection scope of the present invention.

[0020] For a better understanding of the present invention, the above content will be described in detail below in conjunction with specific embodiments.

[0021] Please refer to the attached Figure 1 - attached Figure 9 An embodiment of the present invention provides a dual-fan three-stage electrolytic gas filter, including: an upper shell 1 and a lower shell 2 that are interconnected; a cavity one 101 and a cavity four 102 that are independent of each other are provided inside the upper shell 1, and a cavity two 201, a cavity three 202, and a connection cavity 203 are provided inside the lower shell 2, and the cavity one 101, the cavity two 201, the connection cavity 203, the cavity three 202, and the cavity four 102 are connected in sequence; a macromolecular filter cotton 10, which is located inside one side of the upper shell 1 and is connected to the cavity one 101; a fan one 3 and a fan two 4, which are respectively installed in the cavity one 101 and the cavity four 102; an electrolytic air inlet cylinder 5 and an electrolytic rod 8 are installed on one side of the bottom of the upper shell 1, and both are located in the cavity two 201. The electrolytic air inlet cylinder 5 is used to guide the air flow output by the fan one 3 into the cavity two 201, and water is provided in the cavity two 201; an activated carbon air outlet cylinder 6 is installed on the other side of the bottom of the upper shell 1 and is located in the cavity three 202. The fan two 4 is used to extract the gas in the cavity three 202 along the activated carbon air outlet cylinder 6 to the cavity four 102 and discharge it.

[0022] In this embodiment, the external gas can be drawn into the device by the fan one 3, and the gas in the device can be extracted to the outside by the fan two 4. After the gas enters the device, it will flow sequentially along the cavity one 101, the cavity two 201, the connection cavity 203, the cavity three 202, and the cavity four 102. Therefore, the air flow can pass through the macromolecular filter cotton 10, the electrolytic air inlet cylinder 5, the electrode rod, and the activated carbon air outlet cylinder 6 in sequence. After adding water to the inside of the cavity two 201, the gas can be intercepted for particulate matter, electrolytically decomposed, and harmful gas adsorbed in sequence at this time, so as to achieve the effect of three-stage purification.

[0023] Please refer to the attached Figures 1 - 3 On both sides of the top surface of the upper shell 1, filter meshes 9 are installed. The electrolytic rod 8 is located inside the cavity two 201 close to the connection cavity 203.

[0024] In this embodiment, by installing filter meshes 9 on both sides of the upper shell 1, the filter mesh 9 close to the cavity one 101 can preliminarily filter the particulate matter in the gas entering the outer shell, and the filter mesh 9 close to the cavity two 201 can filter the gas discharged from the cavity four 102. Therefore, the gas purification effect can be further improved.

[0025] Please refer to the attached Figures 2 - 4 , a reverse osmosis molecular membrane 7 is provided in the middle of the lower shell 2, and the reverse osmosis molecular membrane 7 is installed inside the connection cavity 203.

[0026] In this embodiment, by installing the reverse osmosis molecular membrane 7 in the connection cavity 203, the gas flowing through the inside of the connection cavity 203 can be filtered and purified with high precision again, effectively intercepting the fine particles, soluble harmful substances and odor molecules that the previous-stage electrolytic filtration failed to completely remove, and further improving the depth and reliability of the overall gas purification.

[0027] Please refer to the attached Figure 3 , Figure 6 and Figure 7 , a bottom plate 103 is fixedly connected to the bottom of the upper shell 1, a partition plate 104 is fixedly connected to the middle of the top surface of the bottom plate 103, the partition plate 104 is located between the cavity one 101 and the cavity four 102, the first blower 3 and the second blower 4 are installed on both sides of the top surface of the bottom plate 103, and the electrolytic air inlet cylinder 5 and the activated carbon air outlet cylinder 6 are respectively installed on both sides of the bottom surface of the bottom plate 103.

[0028] In this embodiment, by using the bottom plate 103, a relatively sealed space can be formed for the upper shell 1, and by using the partition plate 104, the space inside the upper shell 1 can be divided, so as to form relatively independent cavity one 101 and cavity four 102.

[0029] Please refer to the attached Figure 3 and Figures 6 - 9 , a control electric box 11 is installed on the top of the partition plate 104, a water quality detection component 13 is arranged inside the cavity two 201, and the water quality detection component 13 is connected to the control electric box 11 through a connecting wire 12. The water quality detection component 13 includes a TDS conductivity sensor, a pH electrode sensor, an ORP sensor, an optical turbidity sensor and a water temperature sensor. An installation part 14 is arranged on one side of the top of the partition plate 104, and the control electric box 11 is fixed inside the installation part 14.

[0030] In this embodiment, the control electric box 11 can be installed through the installation part 14 on the partition plate 104, and the connecting wire 12 can transmit the information detected by the water quality monitoring component to the inside of the control electric box 11, so as to monitor the water quality in the chamber two 201 in real time. The detected information includes pH value, TDS value, conductivity, dissolved oxygen, ORP value, water temperature and turbidity. Therefore, the electrolysis parameters can be automatically adjusted according to the water quality change to ensure the stability and high efficiency of the electrolysis process, and avoid equipment operation failures or reduced purification effects caused by abnormal water quality; and the electrolysis rods 8 are set to two, one is the positive electrode and the other is the negative electrode, and the operating parameters of the first fan 3 and the second fan 4 can also be adjusted according to the results of water quality detection. Specifically, when the detected pH value, TDS value and water quality parameters decrease or the water temperature rises, the rotation speeds of the first fan 3 and the second fan 4 are increased to increase the air flow rate and improve the gas dissolution efficiency; on the contrary, when the detected water quality parameters increase or the temperature decreases, the fan rotation speed is adjusted to reduce the air flow rate to maintain a stable electrolysis environment.

[0031] Working principle: When in use, first separate the upper shell 1 and the lower shell 2, then add water into the chamber two 201, and the liquid level of the water needs to submerge the bottom ends of the electrode rods and the electrolysis air inlet cylinder 5, and then reassemble the upper shell 1 and the lower shell 2, and the assembly methods include but are not limited to snap connection, that is, the sealing performance between the upper shell 1 and the lower shell 2 is not affected; During operation, drive the first fan 3 and the second fan 4. The first fan 3 can draw external gas into the electrolysis air inlet cylinder 5 successively through the filter screen 9 and the macromolecule filter cotton 10, and then discharge from the bottom of the electrolysis air inlet cylinder 5 and enter the water in the chamber two 201. At this time, by the discharge action of the electrode rods, the gas entering the water can be subjected to an electrolysis reaction to promote the chemical reaction or dissolution of the gas and water, so as to effectively decompose harmful substances and improve the purification effect. The second fan 4 can extract the gas inside the chamber three 202. At this time, the gas after the hydrolysis reaction will enter the top of the chamber two 201 and enter the chamber three 202 through the connecting chamber 203. At this time, the gas will then enter the chamber four 102 along the activated carbon air outlet cylinder 6 and the fan, and finally pass through the filter screen 9 and be discharged from the device, so as to purify, filter and adsorb the harmful gas generated during the operation of the 3D printer or the laser engraver; And when the gas passes through the connecting chamber 203, the reverse osmosis molecular membrane 7 can finely filter and separate the fine particles, soluble harmful gases and volatile organic compounds in the electrolytically purified air to further remove the residual pollutants therein; At the same time, the water quality monitoring component 13 can be used to monitor the water in the chamber two 201 in real time. By detecting key parameters such as the pH value, TDS (total dissolved solids), turbidity, oxidation-reduction potential (ORP) and water temperature of the water, the water quality stability during the electrolysis process can be ensured, thereby improving the electrolysis efficiency and gas purification effect, and preventing performance fluctuations or equipment damage caused by water quality changes; And after use, by separating the upper shell 1 from the lower shell 2, at this time, the electrolytic air inlet cylinder 5, the semi-permeable molecular membrane, and the activated carbon air outlet cylinder 6 will be in an exposed state, and then the three of them can be replaced randomly.
