Description

Technical Field

[0001] This utility model relates to the field of laminar flow purification hood technology, and in particular to a laminar flow purification hood for improved frozen sperm operation to prevent contamination. Background Technology

[0002] In the wave of transformation and upgrading of modern animal husbandry, bull frozen semen improvement technology is a core tool for improving breeding efficiency. The genes of a superior breeding bull can significantly improve the meat yield of beef cattle and increase the milk production of dairy cows, making its frozen semen resources highly valued by farmers. However, every step from collection to use of bull frozen semen is fraught with challenges. After collection, the semen needs to undergo a series of processes including dilution, testing, and freezing. During dilution, the semen mixes with various nutrients, and if microorganisms or dust from the air are mixed in, it will contaminate the diluent, leading to sperm death. During testing, if contaminants adhere to the microscope slide, it will interfere with the technicians' judgment of sperm motility. During freezing, contaminated containers will also cause the sperm to lose activity at low temperatures. In contrast, operating rooms in the medical field and electronic chip manufacturing workshops have long used laminar flow purification technology to isolate contamination and ensure the safety of high-precision operations. By drawing on this mature technology and applying laminar flow purification hoods to bull frozen semen improvement operations, creating a localized clean space, the contamination problem can be solved at its source, allowing each batch of bull frozen semen to play its maximum value and promoting high-quality development of animal husbandry.

[0003] The structure of the anti-pollution laminar flow purification hood includes an air purification system, an operating chamber structure, a disinfection and sterilization system, auxiliary functional modules, and moving and fixed components. In traditional operating environments, dust, animal hair, and bacterial contaminants raised by personnel moving around in farms and laboratories are ubiquitous. Even with strict disinfection by operators, contaminants from the ordinary environment will still continuously invade the operating area, leading to a decline in frozen semen quality and causing direct economic losses to farmers. The anti-pollution laminar flow purification hood can purify the air through a top high-efficiency filter, removing dust and bacterial contaminants to create a clean operating space. This prevents external impurities from directly contacting the frozen semen and prevents the sperm from losing its activity due to contamination. Furthermore, it adopts a vertical unidirectional laminar flow design to block contamination and ensure that the thawing and packaging of frozen semen are not disturbed by external factors. However, the high degree of integration between the functional components and the main structure means that they cannot be disassembled independently, resulting in the need to affect the entire structure for local maintenance. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an improved laminar flow purification hood for frozen semen operation, which aims to improve the problem in the prior art where the high degree of integration between the functional components and the main structure makes them impossible to disassemble independently, resulting in the need to affect the entire structure for local maintenance.

[0010] As a further description of the above technical solution:

[0011] A support plate is rotatably connected to the top center of the purification shell. An air intake component is provided on the top of the support assembly.

[0012] As a further description of the above technical solution:

[0013] The suction assembly includes two suction fans. The bottom of each suction fan is mounted on the top of the second support plate. The bottom of each suction fan is fixedly connected to a mounting plate. The opposite side of the mounting plate is threaded with a bolt. The bottom of the bolt penetrates the mounting plate and engages with the top of the second support plate. The adjacent side of the mounting plate is threaded with a bolt. The bottom of the bolt penetrates the mounting plate and engages with the top of the second support plate.

Finally, the gas is transmitted through the support plate, meeting the requirements of uniform airflow during operation.

[0022] 2. In this utility model, when a lot of dust and impurities accumulate on the top of the support plate, the engagement between the sliding column and the hole can be canceled, thereby removing the support plate from the air guide plate. This makes it easy to clean. After cleaning and maintenance, the stability of the support plate's position is achieved through the sliding column, ensuring the stability of the equipment structure and the accuracy of the airflow channel. Finally, through the engagement of the second positioning column, it can withstand the airflow pressure during equipment operation and is not prone to displacement, thus ensuring the normal operation of the equipment.

[0040] Working principle: Rotating support plate 2064 provides support for mounting plate 2072.

Sliding U-shaped plate 204 horizontally fixes filter screen 201. Finally, the engagement of positioning post 205 and positioning hole 202 secures filter screen 201. This installation method allows for quick disassembly and replacement of the independent modules, shortening maintenance time. After installation, the air is drawn in by the suction fan 2071 and enters through the filter 1 201. The side air intake is protected by the filter 2 6 and the filter 3 7. After purification and disinfection through the purification shell 2061, the air is discharged to the filter plate 2062 and finally through the support plate 301 for gas transmission. The multi-filtration and sealing design prevents the leakage of harmful microorganisms and ensures that the airflow discharged from the air outlet is a low-turbulence unidirectional laminar flow, meeting the requirements of airflow uniformity during operation.

[0041] When a significant amount of dust and impurities accumulate on the top of the support plate 301, the engagement between the sliding column 306 and the hole 304 can be disengaged, allowing the support plate 301 to be removed from the air guide plate 4. This facilitates cleaning without the need for complex tools or cumbersome operations. After cleaning and maintenance, the sliding column 306 ensures the stability of the support plate 301's position, guaranteeing the stability of the equipment structure and the accuracy of the airflow channel. Finally, the engagement of the positioning column 3071 further enhances the stability of the support plate 301's position, enabling it to withstand airflow pressure during equipment operation and preventing displacement, thus ensuring the normal operation of the equipment.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
