Description

Technical Field

[0001] This invention relates to the field of air purification technology in feed mills, specifically to an odor treatment device for biological feed processing. Background Technology

[0002] Feed is a general term for the food of animals raised by all people. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten kinds of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. During the drying and stacking cooling process, feed processing plants will produce odors and foul gases due to anaerobic fermentation and other effects. Therefore, odor treatment devices are needed to treat them.

[0003] Chinese patent discloses an odor treatment device for feed processing, publication number CN210495860U. The technical solution disclosed in this patent document is as follows: it includes a base, and the top of the base is connected by screws to a shell, a water tank, a UV photolysis purifier and an activated carbon adsorption tower from left to right. One end of the air inlet pipe is provided at the top left side of the shell, and the other end of the air inlet pipe is connected to an external feed processing device. A suction fan is installed in the inner cavity of the air inlet pipe.

[0004] To address the issue that existing devices cannot comprehensively purify and treat odors according to actual conditions, current technology uses a combination of UV photolysis purifiers and activated carbon adsorption towers to treat odor gases more comprehensively. However, this method still fails to provide filtration and protection for the suction fan. During operation, the suction fan is prone to accidentally sucking in impurities such as feed residue. These impurities move into the inner cavity of the suction fan, which can significantly affect its lifespan. Summary of the Invention

[0017] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0018] 1. This invention provides an odor treatment device for biological feed processing. Through the design of the air intake pipe and the cylindrical suction fan, the air drawn by the cylindrical suction fan can flow through the inner cavity of the iron filter box. During this process, the design of the ceramic fiber filter cover completes the initial filtration of the air, filtering out larger impurities in the air. This avoids the problem of large impurities easily causing blockage inside the cylindrical suction fan, extending the service life of the cylindrical suction fan and improving the reliability of this structure.

[0019] 2. This invention provides an odor treatment device for biological feed processing. Through the connection design of the internal threaded receiving pipe and the external threaded pipe, as well as the connection design of the iron filter box and the plug-in frame, the user can disassemble the external threaded pipe and the plug-in frame. Then, the user can operate the cylindrical suction fan to work in reverse, delivering air into the inner cavity of the iron filter box. The airflow can drive the ceramic fiber filter cover to rotate at the bottom of the fixed ring by the driven blades, thereby completing the automatic cleaning of the outer surface of the ceramic fiber filter cover by centrifugal force. At the same time, the thrust of the air can further improve the centrifugal cleaning effect, avoiding the problem of the user manually cleaning the outer surface of the ceramic fiber filter cover, improving the convenience of the structure and reducing the consumption of manpower.

[0020] 3. This invention provides an odor treatment device for biological feed processing. By using a No. 2 ultraviolet germicidal lamp and a No. 1 ultraviolet germicidal lamp in combination, the device emits ultraviolet light after operation to irradiate and sterilize odor gases, thereby reducing the intensity of the odor. At the same time, through the design of reflective lenses and reflective coatings, the light emitted by the No. 2 and No. 1 ultraviolet germicidal lamps can be reflected, thereby increasing the light intensity of the germicidal lamps and further enhancing the sterilization and odor removal effect.

[0021] 4. This invention provides an odor treatment device for biological feed processing. Through the design of a plastic bend, odorous air can flow through its inner cavity. Simultaneously, the activated carbon material inside the plastic bend adsorbs and purifies the odorous air, improving the efficiency of odor purification. A monitoring sensor detects the force exerted by the flowing air inside the cylinder on the wind resistance plate; continuous force indicates continuous airflow through the inner cavity of the plastic bend. A timer keeps track of the time; once a preset value is reached, the device automatically activates an illumination ring to emit warning light, prompting the user to replace the activated carbon material inside the plastic bend in a timely manner, thus ensuring the effectiveness of odor purification.

[0040] Example 4

[0041] like Figure 1-8As shown, based on Embodiment 3, the present invention provides a technical solution: Preferably, the adsorption purification unit includes a hollow diversion cylinder 39, a bottom support 392 is fixedly installed at the bottom of the hollow diversion cylinder 39, the bottom support 392 is movably connected to the top of the processing workbench 1, a protruding tube 391 is fixedly connected to the outer wall of the hollow diversion cylinder 39, and an insertion tube 393 is movably inserted into the end of the protruding tube 391 away from the hollow diversion cylinder 391, and the end of the insertion tube 393 away from the protruding tube 391 is fixedly connected to...

The air flowing inside the monitoring cylinder 396 will exert a thrust on the wind deflector 3963, and the pressure sensor 3962 will simultaneously monitor this force. If the force continues, it means that the air continues to flow through the inner cavity of the plastic bend 394. At the same time, the timer 3964 will keep track of the time.

Control the cylindrical suction fan 271 to operate, which can absorb the odor. The odorous gas first flows through the inner cavity of the iron filter chamber 21, where it undergoes initial filtration by the ceramic fiber filter cover 266. The odorous gas then flows through the inner cavity of the curved glass tube 36. The user can simultaneously control the operation of the first ultraviolet germicidal lamp 323 and the second ultraviolet germicidal lamp 371 to sterilize and remove odors from the gas. Finally, the odorous gas passes through the plastic... The material flows through the inner cavity of the plastic bend tube 394, and the activated carbon material inside the plastic bend tube 394 completes the adsorption and purification of odorous gases. When this structure is not in use, if it is necessary to clean the ceramic fiber filter cover 266, remove the external threaded tube 273 from the internal threaded receiving tube 272, and then remove the plug frame 25 from the bottom of the iron filter box 21.
