Description

Technical Field

[0001] This utility model relates to the field of gas filtration technology, and in particular to a novel gas filtration device for environmental protection equipment. Background Technology

[0002] Gas filters are widely used in metallurgy, chemical industry, petroleum, papermaking, pharmaceutical, food, mining, power, and urban water supply. Meanwhile, with the increase in the number of cars in cities, air quality is inevitably affected. In order to ensure indoor air quality, a new type of environmentally friendly gas filtration device has been proposed.

[0003] Existing equipment, such as CN218190270U, ​​is a novel gas filtration device for environmental protection. It includes a main body with a pulverizing mechanism inside. The pulverizing mechanism comprises a housing, a motor, pulverizing blades, a barrier net, a pressure plate, and an electric push rod. The housing is fixedly connected to the left inner surface of the main body. The electric push rod is fixedly connected to the inner top of the housing. The pressure plate is fixedly connected to the movable end of the electric push rod. The barrier net is fixedly connected to the inner surface of the housing. The pulverizing blades are fixedly connected to the output end of the motor. The lower surface of the barrier net contacts the upper surface of the pulverizing blades. A fixing rod is fixedly connected to the inner surface of the housing, and the fixing rod, away from the inner surface of the housing, is fixedly connected to the surface of the motor. This structure can pulverize inhaled debris, such as hair and lint, helping to prevent debris accumulation and thus affecting airflow efficiency.

[0004] The aforementioned equipment is insufficient in filtering various harmful pollutants in the gas. It cannot effectively purify harmful gases and tiny dust particles in the air, making it difficult to meet the high standards of indoor and outdoor air quality. With continuous use of the filtration device, impurities will gradually accumulate on the filter components, reducing filtration efficiency and even clogging the filter channels. The aforementioned equipment is not equipped with a self-cleaning device and requires manual disassembly and cleaning periodically, which is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to solve the problems of limited filtration effect and lack of self-cleaning function of existing devices, and to propose a new type of gas filtration device for environmental protection equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel gas filtration device for environmental protection equipment, comprising a filter box, a mounting groove, a filter device, a self-cleaning device, and a gas detector. The mounting groove is formed on the inner wall of the filter box. The filter device is fixedly connected to the inner wall of the mounting groove. The self-cleaning device is fixedly connected to the bottom of the filter device. The gas detector is fixedly connected to the inner wall of the filter box. The filter device includes a fixing frame. The left and right sides of the fixing frame are fixedly connected to clamping plates. The clamping plates are clamped to the inner wall of the mounting groove. The surface of the fixing frame has three clamping slots. The inner walls of the clamping slots are clamped to filter screens. There are three filter screens with different filter aperture sizes.

[0007] Furthermore, an adsorption rack is fixedly connected to the inner wall of the filter box, and an activated carbon filter layer and an alkaline filter layer are fixedly connected to the inner wall of the adsorption rack.

[0008] Furthermore, the self-cleaning device includes circular grooves formed on the upper and lower surfaces of the card plate, and a damping spring is fixedly connected to the inner wall of the circular groove.

[0009] Furthermore, the bottom of the damping spring is fixedly connected to the inner wall of the mounting groove, and an electromagnetic vibrator is fixedly connected to the bottom of the fixing frame.

[0010] Furthermore, a spring is fixedly connected to the bottom wall of the electromagnetic vibrator, and the bottom of the spring is fixedly connected to the inner bottom wall of the groove.

[0011] Furthermore, the groove is formed on the inner wall of the filter box, and the inner bottom wall of the filter box is provided with a slot, and a protective cylinder is fixedly connected to the inner bottom wall of the slot.

[0012] Furthermore, a fan is fixedly connected to the inner bottom wall of the protective cylinder, and an isolation net is fixedly connected to the air outlet end of the inner wall of the protective cylinder.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a filtration device and utilizing the cooperation of a fixing frame and a clamping plate, the filtration device can be conveniently and quickly installed in the mounting slot inside the filter box. The three filter screens with different pore sizes in the three slots can sequentially perform multi-stage filtration of the gas. The large-pore filter screen first intercepts larger particles of dust, debris, and other impurities, and then the smaller-pore filter screen further filters out tiny particles, achieving fine initial filtration of the gas. The activated carbon filter layer on the adsorption frame effectively adsorbs odors, organic pollutants, and some harmful gases in the gas; the alkaline filter layer neutralizes acidic pollutants in the gas, converting them into harmless or less harmful substances. Through the synergistic effect of the multi-stage filter screens, activated carbon filter layer, and alkaline filter layer, the gas filtration effect is greatly improved, effectively purifying various harmful pollutants and meeting the high standard requirements for gas purification in different scenarios.

[0015] 2. In this utility model, a self-cleaning device is set up, which uses a circular groove on the card plate connected to a damping spring. The bottom of the damping spring is fixed to the inner wall of the mounting groove, which can effectively buffer and absorb the vibration generated during the self-cleaning process, ensuring stable operation of the equipment. The electromagnetic vibrator at the bottom of the fixed frame generates high-frequency vibration after being energized, which is transmitted to the filter screen, causing the impurities attached to the filter screen to fall off. The spring on the bottom wall of the electromagnetic vibrator is connected to the groove on the inner wall of the filter box. The protective cylinder protects the fan. After the fan is started, it generates a strong airflow, which cleans the impurities in the filter device by wind. The self-cleaning device realizes automatic cleaning of the filter screen, reduces the frequency of manual cleaning, ensures that the filter device always maintains good filtration performance, and improves the working efficiency and service life of the equipment.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a novel gas filtration device for environmental protection equipment, comprising a filter box 1, an installation groove 2, a filter device 3, a self-cleaning device 4, and a gas detector 5. The installation groove 2 is formed on the inner wall of the filter box 1, the filter device 3 is fixedly connected to the inner wall of the installation groove 2, the self-cleaning device 4 is fixedly connected to the bottom of the filter device 3, and the gas detector 5 is fixedly connected to the inner side wall of the filter box 1.

[0024] The following section will describe in detail the specific setup and function of its filter device 3 and self-cleaning device 4.

[0025] In this embodiment: the filter device 3 includes a fixing frame 31, and the left and right sides of the fixing frame 31 are fixedly connected with the clamping plates 32. The clamping plates 32 are clamped to the inner wall of the mounting groove 2. The surface of the fixing frame 31 is provided with three slots 33. The inner wall of the slots 33 is clamped to a filter screen 34. There are three filter screens 34 with different filter hole sizes.

[0026] The effect achieved by the above-mentioned components is as follows: by setting three slots 33, installation positions are provided for filter screens 34 with different filter pore sizes. The three filter screens 34 have different filter pore sizes, which can filter the gas in multiple stages in sequence. First, the larger pore size filter screen 34 filters out the larger particulate impurities in the gas. Then, the smaller pore size filter screen 34 filters out the smaller particulate pollutants in the gas, thereby achieving fine filtration of the gas and improving the filtration effect.

[0027] Specifically, an adsorption rack 35 is fixedly connected to the inner wall of the filter box 1, and an activated carbon filter layer 36 and an alkaline filter layer 37 are fixedly connected to the inner wall of the adsorption rack 35.

[0028] The effects achieved by the above components are as follows: by setting up the adsorption rack 35, an installation carrier is provided for the activated carbon filter layer 36 and the alkaline filter layer 37. The activated carbon filter layer 36 can adsorb odors, organic pollutants and some harmful gases in the gas; the alkaline filter layer 37 can neutralize acidic pollutants in the gas and convert them into harmless or less harmful substances.

[0029] Specifically, the self-cleaning device 4 includes a circular groove 41 formed on the upper and lower surfaces of the card plate 32, and a damping spring 42 is fixedly connected to the inner wall of the circular groove 41.

[0030] The effect achieved by the above components is as follows: by setting the damping spring 42, it has the function of buffering and shock absorption. When the self-cleaning device 4 is working, the filter device 3 will generate a certain vibration. The damping spring 42 can effectively absorb and buffer these vibrations, reduce the impact of vibration on the filter box 1 and other components, and ensure the overall stability of the equipment.

[0031] Specifically, the bottom of the damping spring 42 is fixedly connected to the inner wall of the mounting groove 2, and the bottom of the fixing frame 31 is fixedly connected to the electromagnetic vibrator 43.

[0032] The effect achieved by the above components is as follows: by setting up the electromagnetic vibrator 43, when the electromagnetic vibrator 43 is powered on, it will generate high-frequency vibration, which will be transmitted to the fixed frame 31 and the filter screen 34 connected thereto, causing the impurities attached to the filter screen 34 to fall off under the action of vibration. Through the vibration of the electromagnetic vibrator 43, the filter screen 34 is automatically cleaned, reducing the frequency of manual cleaning and improving the working efficiency of the equipment.

[0033] Specifically, a spring 44 is fixedly connected to the bottom wall of the electromagnetic vibrator 43, and the bottom of the spring 44 is fixedly connected to the inner bottom wall of the groove 45.

[0034] The effect achieved by the above components is as follows: by setting the spring 44, the vibration generated by the electromagnetic vibrator 43 is rebounded, so that the strong vibration generated by the electromagnetic vibrator 43 when it is working is directly transmitted to the filter box 1, and the filter screen 34 is cleaned by self-vibration.

[0035] Specifically, the groove 45 is formed on the inner wall of the filter box 1, and the inner bottom wall of the filter box 1 is provided with a slot 46, and a protective cylinder 47 is fixedly connected to the inner bottom wall of the slot 46.

[0036] The effect achieved by the above components is as follows: by setting the slot 46, an installation position is provided for the protective cylinder 47; the protective cylinder 47 can protect the internal fan 48 and prevent the fan 48 from being interfered with and damaged by external impurities.

[0037] Specifically, a fan 48 is fixedly connected to the inner bottom wall of the protective cylinder 47, and an isolation net 49 is fixedly connected to the air outlet end of the inner wall of the protective cylinder 47.

[0038] The effect achieved by the above components is as follows: by setting up the fan 48, when the fan 48 is started, a strong airflow will be generated. The generated airflow can clean the impurities in the filter device by wind power, and prevent the impurities from re-attaching to the filter device 3 or circulating in the filter box 1, thus affecting the gas filtration effect.

[0039] Working principle: By setting up the filter device 3 and utilizing the cooperation of the fixing frame 31 and the clamping plate 32, the filter device 3 can be conveniently and quickly installed in the mounting slot 2 inside the filter box 1. The three filter screens 34 with different pore sizes in the three slots 33 can sequentially perform multi-stage filtration of the gas. The large-pore filter screen 34 first intercepts larger particles of dust, debris and other impurities, and then the smaller-pore filter screen 34 further filters out tiny particles, achieving fine initial filtration of the gas. The activated carbon filter layer 36 on the adsorption frame 35 effectively adsorbs odors, organic pollutants and some harmful gases in the gas; the alkaline filter layer 37 neutralizes acidic pollutants in the gas, converting them into harmless or less harmful substances. Through the synergistic effect of the multi-stage filter screens 34, activated carbon filter layer 36 and alkaline filter layer 37, the gas filtration effect is greatly improved, which can effectively purify various harmful pollutants and meet the high standard requirements for gas purification in different scenarios.

[0040] By setting up a self-cleaning device 4, the circular groove 41 on the card plate 32 is connected to the damping spring 42. The bottom of the damping spring 42 is fixed to the inner wall of the mounting groove 2, which can effectively buffer and absorb the vibration generated during the self-cleaning process, ensuring stable operation of the equipment. When the electromagnetic vibrator 43 at the bottom of the fixing frame 31 is powered on, it generates high-frequency vibration, which is transmitted to the filter screen 34, causing the impurities attached to the filter screen 34 to fall off. The spring 44 on the bottom wall of the electromagnetic vibrator 43 is connected to the groove 45 on the inner wall of the filter box 1. The protective cylinder 47 protects the fan 48. After the fan 48 is started, it generates a strong airflow, which cleans the impurities in the filter device 3 by wind. The self-cleaning device 4 realizes the automatic cleaning of the filter screen 34, reduces the frequency of manual cleaning, ensures that the filter device 3 always maintains good filtration performance, and improves the working efficiency and service life of the equipment.
