Description

Technical Field

[0001] This utility model relates to the field of dust removal and deodorization ventilation technology, specifically a dust removal and deodorization ventilation device. Background Technology

[0002] In today's society, with the acceleration of industrialization and the continuous improvement of people's living standards, indoor air quality has received increasing attention. The large amounts of dust- and odor-laden gases generated during industrial production, as well as the odors emitted from daily environments such as garbage disposal sites, public toilets, and restaurants, not only pose potential threats to people's health, such as causing respiratory diseases and allergic reactions, but also seriously affect their comfort and quality of life. Therefore, developing efficient dust and odor removal ventilation equipment to improve air quality has become an urgent task.

[0003] Early dust removal equipment primarily used mechanical filtration, intercepting dust particles through filters. However, this method was ineffective at filtering fine particles, and the filters were prone to clogging, leading to increased equipment resistance, reduced airflow, and the need for frequent filter replacements, thus increasing maintenance costs and workload. As for odor control, ventilation dilution was commonly used in the past. This method might be effective at low odor concentrations, but its effectiveness was extremely limited for high-concentration, continuously emitted odors, failing to address the problem at its root.

[0004] Therefore, a dust removal and deodorization ventilation device is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, some early dust removal equipment primarily used mechanical filtration, intercepting dust particles through filter screens. However, this method is ineffective at filtering fine particles, and the filters are prone to clogging, leading to increased equipment resistance, reduced airflow, and the need for frequent filter replacements, thus increasing maintenance costs and workload. Regarding odor control, the traditional method of ventilation dilution may be effective at low odor concentrations, but its effectiveness is extremely limited for high-concentration, continuously emitted odors, failing to fundamentally solve the problem.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The dust removal and deodorization ventilation equipment of this utility model includes a gas collection and filtration assembly.

[0012] Preferably, the deodorizing filter body and the filter slot form an engaging structure, and the filter slot and the support plate are integrated. The support plate forms a sliding structure with the slider, the groove and the support rod. The limiting rod forms an elastic structure with the metal shell through the first spring, and the limiting rod and the metal shell are arranged to coincide with the vertical central axis.

[0013] The advantages of this utility model are: 1. This utility model, through the integration of a gas collection and filtration component, a unique gas collection height adjustment component, and a replaceable deodorizing component, provides powerful functional integration for the device. The gas collection height adjustment component allows for flexible adjustment of the gas collection height according to different usage scenarios and needs, enabling the device to accurately capture the gases requiring treatment. Whether it's odors near the ground or dust-laden gas at higher altitudes, it can effectively collect them, greatly improving the device's applicability and specificity.

[0014] 2. This utility model features a gas collection height adjustment component, the core of which lies in its ingenious lifting structure. A motor is installed at the top of the support column and cleverly connected to a gear, allowing the motor's rotation to precisely drive the gear's rotation. The meshing of the gear and rack cleverly converts the motor's rotational motion into the rack's linear motion. The rack's up-and-down movement is transmitted to the retaining ring via a moving rod, thus achieving the ring's lifting and lowering. This design is not only compact but also highly efficient, enabling quick and smooth adjustment of the gas collection height. The ingenuity of this lifting structure lies in its height flexibility and precision. Precise motor control allows for fine-tuning of the retaining ring's lifting and lowering according to actual needs, easily accommodating both minor adjustments and larger height changes. This flexibility allows the equipment to adapt to various complex operating environments, from low-lying spaces near the ground to higher gas collection positions, ensuring the equipment is always in the optimal gas collection position, improving its applicability and working efficiency. Furthermore, the stability of this structure is also commendable. The tight meshing of gears and racks ensures the stability and reliability of the transmission process, maintaining good working condition even under long-term operation and frequent adjustments. This stable lifting structure provides strong support for the long-term stable operation of the equipment, reducing downtime caused by mechanical failures and improving the reliability and service life of the equipment. Furthermore, this design offers excellent maintainability and scalability. The installation and connection methods of key components such as motors and gears make maintenance and replacement simple and quick. If upgrades or functional expansions are needed, this structure can be easily adjusted and improved, providing ample room for future development of the equipment.

[0015] 3. This utility model features a convenient deodorizing component, the core of which lies in its unique sliding and engaging structure. The sliding groove at the top of the support rod, in conjunction with the slider, provides a stable lateral movement track for the support plate. This sliding structure allows users to easily pull out or push in the support plate, facilitating the replacement of the deodorizing filter element. At the top of the slider, the filter element slot engages with the deodorizing filter element body, ensuring not only a secure installation but also easy removal when needed. This engaging structure eliminates the need for complex tools or cumbersome steps in filter element replacement, allowing users to quickly complete the operation, reducing equipment downtime and improving maintenance efficiency. Furthermore, the elastic structure of the first spring and the limiting rod inside the metal shell provides additional protection for the filter element's fixation. The limiting rod, through the elastic action of the first spring, maintains close contact with the filter element, preventing it from loosening or shifting due to vibration during equipment operation. This elastic structure not only enhances the stability of the filter element but also accommodates filter elements of different sizes, improving equipment compatibility. Meanwhile, the aligning of the limiting rod with the vertical central axis of the metal shell ensures uniform force distribution and further enhances structural stability. The integrated design of the filter cartridge slot and support plate not only improves the overall structural strength but also reduces connection errors between components, making the entire assembly more compact and stable. This integrated design allows the equipment to maintain good working condition during long-term operation, reducing the risk of malfunctions due to loose or damaged components.

[0024] Working Principle: First, the gas collection and filtration assembly 1 is the core component of the equipment. Its horn-shaped air inlet 101 can extensively collect dust and odors from the air. The horn-shaped air inlet 101 is connected to the filter housing 102 via a threaded connection. This detachable structure facilitates cleaning and maintenance of the air inlet by the user. Gas enters the filter housing 102 through the horn-shaped air inlet 101. Under the action of the internal filter screen 103 and desiccant 104, dust is filtered and moisture is absorbed, thus achieving preliminary purification. The combined use of filter screen 103 and desiccant 104 not only improves dust removal efficiency but also effectively removes moisture from the air, preventing filter screen 103 from clogging and extending its service life. The gas that has undergone preliminary filtration enters the suction pump 106 through the air inlet pipe 105. The suction pump 106 provides power to extract the gas and discharge it through the air outlet pipe 107. The engaging structure between the air inlet pipe 105 and the filter housing 102 ensures a stable connection between the air inlet pipe 105 and the filter housing 102. Its expandable nature allows the device to adapt to different installation spaces and usage scenarios, improving its flexibility and adaptability. The gas collection height adjustment component 2 provides height adjustment functionality. A motor 202 at the top of the support column 201 drives a gear 203 to rotate. The gear 203 meshes with a rack 204, allowing the rack 204 to move up and down. The movement of the rack 204 is transmitted to the retaining ring 206 via a moving rod 205, thus raising and lowering the retaining ring 206. This lifting structure allows the device to flexibly adjust the gas collection height according to different usage scenarios and needs, ensuring the device is always in the optimal gas collection position, improving its applicability and working efficiency. The design for easy replacement of the deodorizing component 3 further enhances the ease of maintenance. The cooperation between the sliding groove 309 at the top of the support rod 301 and the slider 302 allows the support plate 303 to slide along the sliding groove 309. The filter cartridge slot 304 at the top of the support plate 303 and the deodorizing filter cartridge body 305 form an engaging structure. This design allows the deodorizing filter cartridge body 305 to be securely installed in the filter cartridge slot 304, while also facilitating quick filter cartridge replacement by the user. Inside the metal shell 306, the first spring 307 and the limiting rod 308 form an elastic structure. Through the elastic action of the first spring 307, the limiting rod 308 can maintain tight contact with the deodorizing filter cartridge body 305, preventing the filter cartridge from loosening or shifting due to vibration during equipment operation. This elastic structure not only enhances the stability of the filter cartridge but also accommodates filter cartridges of different sizes, improving the compatibility of the equipment.
