Description

A dust removal device for the main duct of the IVC cage air supply and exhaust duct Technical Field

[0001] The invention relates to a dust removal device for main pipelines of air supply and exhaust pipes of an IVC cage frame. Background Art

[0002] In the history of human life science development, experimental animals are an important part of life science research. The dedication of experimental animals has accelerated the process of human exploration of the mysteries of life and revealing the mechanisms of diseases. They have made important contributions to human health and scientific development. According to incomplete statistics, in 2021, my country used more than 52 million experimental animals each year, of which rodents and mice accounted for more than 90% of the total usage, and the usage increased by about 15% each year. The level of microbial control of rodent experimental animals (mice and mice) is crucial to the development of scientific research, and the level of microbial control is closely related to the cleaning and disinfection of our daily feeding equipment. At present, the mainstream feeding equipment for feeding mice in the industry is the IVC feeding equipment system, which consists of three parts: IVC host, cage rack and cage box. The IVC host is the power and control device that provides clean air to the cages on the cage rack. The air in the barrier environment becomes cleaner after being efficiently filtered by the host and is transmitted to each individual cage through the air supply pipe of the IVC cage rack. The cage rack is a stainless steel frame structure used to support the placement of the cages. The cage rack is equipped with a cage air intake and exhaust pipe system, which can be set to a rack with different cage numbers according to needs. The cages are made of stainless steel, polyphenylene sulfone resin and high-temperature resistant plastic products. The cage inlet and outlet holes can be connected to the inlet and outlet terminals of each cage on the cage rack to ensure that the gas is evenly delivered to the cages. After the air flow circulates in the cage, the exhaust gas in the cage is discharged through the cage box and cage rack exhaust pipe. In this way, the entire IVC system forms a one-way air flow, and the air in the cage remains clean, ensuring the breeding environment of SPF mice and rats.

[0003] In addition to the main unit, the cages and boxes of the above IVC breeding equipment systems need to be regularly replaced, cleaned, and disinfected to ensure that the microbial control level of experimental mice and rats reaches the SPF level. For the cleaning of the long strip supply and exhaust ducts about 1-2 meters long on the cages, especially the exhaust ducts, the facility managers currently do not have special and efficient tools to fully clean the ducts. If this continues for a long time, the consequences may affect the animal microbial control level, shorten the service life of the equipment, and increase hidden dangers to the normal operation of the experimental animal facilities. Technical issues

[0004] To solve the above technical problems, the present invention proposes a dedicated IVC cage supply and exhaust air duct main duct dust removal device, which can efficiently treat the dust accumulated in the supply and exhaust air ducts for a long time, ensuring that the subsequent disinfection effect meets the standards, thereby ensuring that the microbial control level of experimental animals meets the requirements, maintaining the safe operation of animal facilities, and ensuring the smooth progress of scientific research.

The telescopic rod assembly 2 comprises at least two rods, with adjacent rods secured in place by a fixing assembly. In this embodiment, the telescopic rod assembly 2 comprises three hollow rods, namely a first rod 21, a second rod 22, and a third rod 23, which are arranged in a sequentially arranged manner. The diameters of the first rod 21, the second rod 22, and the third rod 23 decrease in order. Referring to FIG2 , the first rod 21 and the second rod 22 are each provided with two rows of symmetrically arranged through holes 28. The second rod 22 and the third rod 23 are each provided with a fixing assembly, which includes an elastic member 24. Referring to FIG3 , the elastic member 24 is an arched structure, with a buckle 25 fixed at each end of the elastic member 24. The buckle 25 includes a base 26 and a support section 27. Both the base 26 and the support section 27 are cylindrical structures. The support section 27 is fixed to the base 26 and arranged concentrically. The end of the support section 27 is configured as a hemispherical structure to facilitate entry into the through hole of the rod. The outer diameter of the support section 27 is smaller than the diameter of the through hole 28 of the corresponding rod, while the outer diameter of the base 26 is larger than the diameter of the through hole 28 of the corresponding rod.

[0036] Referring to Figure 1, a fixing component is fixed in the second rod 22, and its two clips 25 extend from the through holes corresponding to the first rod 21 and the second rod 22 respectively, so as to achieve the positioning of the first rod 21 and the second rod 22; a fixing component is set in the third rod 23, and its two clips 25 extend from the through holes corresponding to the third rod 23 and the second rod 22 respectively, so as to achieve the positioning of the third rod 23 and the second rod 22.

[0037] The cleaning end assembly 3 includes a first fastening section 31 and a second fastening section 32. The first fastening section 31 and the second fastening section 32 are both cylindrical structures. The diameter of the first fastening section 31 is smaller than the diameter of the second fastening section 32. The two are fixedly connected and concentrically arranged; one end of the first fastening section 31 away from the second fastening section 32 is connected to the telescopic rod assembly 2.
