Description

Technical Field

[0001] This utility model belongs to the field of cleanroom technology, specifically an indoor cleanroom ventilation and fireproof structure. Background Technology

[0002] As living standards improve, people are paying increasing attention to indoor air quality. In ordinary residences, clean air is fundamental to creating a comfortable living environment. In workplaces, good ventilation can improve employee productivity and health. For special functional spaces, the requirements are even more stringent. For example, in electronic chip manufacturing workshops, dust particles can cause chip short circuits and performance degradation, requiring an extremely clean environment. Therefore, there is an urgent need in the market for an indoor cleanroom ventilation and fireproof structure.

[0003] Meanwhile, the patent specification with application number CN218328497U discloses an indoor dust-free ventilation and fireproof structure, "including a ventilation pipe, a positioning groove on the bottom inner wall of the ventilation pipe, a clamping plate installed on the top inner wall of the ventilation pipe, a rectangular frame on one side wall of the ventilation pipe, a positioning block installed at the bottom of the rectangular frame, and the positioning block and the positioning groove are engaged, a dust filter is installed on one side wall of the rectangular frame, a sliding rod is fixedly installed on one side wall of the rectangular frame, and a first L-shaped plate and a second L-shaped plate are slidably connected on the side wall of the sliding rod, with the second L-shaped plate located on one side of the first L-shaped plate. Through the positioning groove, clamping plate, rectangular frame, dust filter, sliding rod, first L-shaped plate, second L-shaped plate, spring, pull ring and positioning block, the dust filter can be quickly disassembled, making it more convenient to disassemble. Timely disassembly and cleaning will also improve its dustproof effect, improve the user experience and have good practicality."

[0004] Existing indoor ventilation devices often have filters with a single structure, which cannot effectively classify and filter pollutants of different particle sizes, resulting in unsatisfactory indoor air purification effects. Furthermore, most lack reasonable cleaning assistance designs. Manually cleaning the filter frame not only requires tedious disassembly but also makes it difficult to thoroughly remove stubborn dust from gaps and corners, thus greatly reducing the filtration effect.

[0005] Therefore, an indoor dust-free ventilation and fireproof structure is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an indoor dust-free ventilation and fireproof structure, which greatly improves the efficiency and convenience of cleaning dust from the filter rack and effectively purifies indoor air, significantly improving indoor air quality and creating a fresher and healthier indoor environment for users.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an indoor dust-free ventilation and fireproof structure, comprising a ventilation duct, an air supply fan installed on the inner surface of the ventilation duct, and a dustproof mechanism installed on the inner surface of the ventilation duct. The dustproof mechanism includes three filter frames, which are arranged parallel to each other at intervals along the length of the ventilation duct. The three filter frames are in contact with and slidably connected to the inner circumferential wall of the ventilation duct. The inner surfaces of the three filter frames are provided with filter layers of different materials, which are, in order, a primary filter layer, a medium-efficiency filter layer, and a high-efficiency filter layer, starting from the side closest to the air supply fan. The three filter frames are arranged at an angle. The inner bottom wall of the ventilation duct and the bottom side of the filter frames are provided with dust collection boxes. The dust collection boxes are provided in three sets and correspond one-to-one with the filter frames.

[0008] Preferably, the material of the primary filter layer is non-woven fabric, the material of the secondary filter layer is activated carbon, and the material of the high-efficiency filter layer is glass fiber.

[0010] Preferably, a protective net is fixedly connected to the opening of the ventilation duct near the blower, and the protective net is made of aluminum alloy.

[0011] Preferably, the upper inner wall of the ventilation duct has a rectangular groove, and two long rods are fixedly connected to the inner walls of both sides of the rectangular groove. The inner surfaces of the three filter frames are slidably sleeved with the outer surfaces of the two long rods. Three springs are wound around the outer surfaces of the two long rods, and the corresponding two springs are fixedly connected to one of the filter frames. A cam is provided on one side of each of the three filter frames. The top of each of the three cams passes through the ventilation duct and is fixedly connected to a sprocket.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses three different filter frames made of different materials. The different filter layers work together to filter the air in an all-round and multi-level manner, effectively purifying indoor air, significantly improving indoor air quality, and creating a fresher and healthier indoor environment for users.

[0016] 2. This utility model, by setting up a dustproof mechanism, causes the filter frame to slide back and forth on the long rod under the action of the rotating cam of the power motor and the action of the spring. The dust attached to the surface of the filter frame is affected by the vibration and falls off. The fallen dust slides down to the dust collection box below.

[0028] 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.

[0029] like Figures 1 to 5As shown, this utility model provides an indoor dust-free ventilation and fireproof structure, including a ventilation pipe 1, a blower 47 installed on the inner surface of the ventilation pipe 1, and a dustproof mechanism 4 installed on the inner surface of the ventilation pipe 1.

[0030] The dustproof mechanism 4 includes three filter frames 48, which are arranged parallel to each other along the length of the ventilation duct 1. The three filter frames 48 are in contact with and slidably connected to the inner circumferential wall of the ventilation duct 1. The inner surface of each of the three filter frames 48 is provided with a filter layer of different materials, which are arranged sequentially from the side closest to the blower 47 as a primary filter layer 432, a medium-efficiency filter layer 433, and a high-efficiency filter layer 434. The three filter frames 48 are arranged at an angle. The bottom wall of the ventilation duct 1 and the bottom side of the filter frames 48 are provided with dust collection boxes 3. There are three sets of dust collection boxes 3, which correspond one to one of the filter frames 48. The angle of the filter frames 48 facilitates the natural sliding of dust into the dust collection boxes 3 during the cleaning process. The filter layers of different materials can filter dust and impurities of different particle sizes in the air in a graded manner.

[0031] Specifically, the pre-filter layer 432 is made of non-woven fabric. Non-woven fabric has a low cost and a certain filtration capacity, making it suitable as a pre-filter material. It can initially intercept large dust particles. The medium-efficiency filter layer 433 is made of activated carbon. Activated carbon has a rich porous structure and a strong adsorption capacity for odors, harmful gases, and fine particles. As the medium-efficiency filter layer 433, it can effectively purify the air. The high-efficiency filter layer 434 is made of glass fiber. Glass fiber has extremely small pores and can efficiently filter extremely fine particles. As the high-efficiency filter layer 434, it ensures the final air filtration quality. The synergistic effect of multiple materials comprehensively improves the air filtration effect.

[0032] like Figures 1 to 5 As shown, the inner walls on both sides of the ventilation pipe 1 are provided with sliding grooves 43, one end of each of the three dust collection boxes 3 is coated with magnetic coating 31, and iron sheets are installed on the inner surfaces of the ventilation pipe 1 and the three dust collection boxes 3 that are in contact with each other.

[0033] Furthermore, a protective net 2 is fixedly connected to the opening of the ventilation duct 1 near the blower 47. The protective net 2 is made of aluminum alloy. The protective net 2 can prevent large foreign objects from entering the ventilation duct 1, avoid damaging the internal structure of the blower 47, and extend the service life of the equipment. The aluminum alloy material has good strength and corrosion resistance, and can play a stable role for a long time while ensuring the protective function.

[0034] like Figures 1 to 5As shown, a rectangular groove 41 is provided on the upper inner wall of the ventilation duct 1. Two long rods 50 are fixedly connected to the inner walls of both sides of the rectangular groove 41. The inner surfaces of three filter frames 48 are slidably sleeved with the outer surfaces of the two long rods 50. Three springs 49 are wound around the outer surfaces of the two long rods 50. The corresponding two springs 49 are fixedly connected to one of the filter frames 48. A cam 42 is provided on one side of each of the three filter frames 48. The top of each of the three cams 42 passes through the ventilation duct 1 and is fixedly connected to a sprocket 45. The outer surfaces of the three sprockets 45 are meshed with a chain 46. A heat insulation box 5 is fixedly connected to the top of the ventilation duct 1. A power motor 44 is fixedly connected to the upper inner wall of the heat insulation box 5. The output end of the power motor 44 is fixedly connected to one of the sprockets 45. This structural design allows for regular cleaning of the filter frames 48, preventing the filter frames 48 from becoming clogged due to dust accumulation and ensuring its continuous and efficient filtration performance.

[0035] It is worth noting that the inner walls on both sides of the ventilation pipe 1 are provided with sliding grooves 43, and the two ends of the three filter frames 48 are fixedly connected with sliders 431 that cooperate with the sliding grooves 43, so that the cleaning process of the filter frames 48 can be carried out smoothly, reducing the occurrence of jamming and other phenomena, and improving the reliability of equipment operation.

[0036] like Figures 1 to 5 As shown, the ventilation duct 1 is made of stainless steel. Stainless steel has good strength, corrosion resistance and fire resistance. In the ventilation and fireproof structure, it can ensure that the ventilation duct 1 is not easily damaged during long-term use, and can effectively prevent the spread of fire through the ventilation duct 1 in the event of a fire, thereby improving indoor safety.

[0037] The power motor 44 and the blower 47 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0038] Working principle and process: When indoor air supply is required, the blower 47 is started, introducing outside air into the ventilation duct 1. The air passes through the primary filter layer 432, the medium-efficiency filter layer 433, and the high-efficiency filter layer 434 in sequence. Dust and impurities of different particle sizes are intercepted and filtered by each level of filter layer. The power motor 44 starts periodically, and its output end drives the sprocket 45 connected to it to rotate. Through the chain 46, the other two sprockets 45 rotate synchronously, which in turn drives the cam 42 to rotate. The cam 42 squeezes the filter frame 48, causing it to slide on the long rod 50 against the elastic force of the spring 49. When the cam 42 rotates away from the filter frame 48, the spring 49 resets, causing the filter frame 48 to spring back. During this process, the dust on the filter frame 48 is shaken off into the dust collection box 3. The protective net 2 can effectively prevent large foreign objects from entering the ventilation duct 1. The stainless steel ventilation duct 1 ensures structural strength, corrosion resistance, and fire resistance, thereby achieving the function of indoor dust-free ventilation and fire prevention.
