Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology for bio-fermented feed, and in particular to an exhaust gas treatment device for bio-fermented feed. Background Technology

[0002] Waste gas treatment during bio-fermentation feed production is a crucial environmental protection step, aiming to reduce the emission of malodorous gases during the production process and protect the environment and human health. The production of bio-fermented feed generates a large amount of malodorous waste gas containing harmful substances such as organic matter and sulfides. If released directly into the atmosphere without treatment, it will cause serious harm to the environment and human health. Therefore, effective waste gas treatment is an essential part of the bio-fermentation feed production process.

[0003] For example, the patent application number published on the China Patent Network is 202320102350.3, and the patent name is: Bio-fermentation Feed Tail Gas Treatment Device. It includes a treatment cylinder, with support legs evenly and equidistantly fixed at the lower end of the treatment cylinder, a cylinder cover snapped onto the upper end of the treatment cylinder, a waste gas pipe slidably installed inside the cylinder cover, a gas collection hood fixedly installed on the side wall of the waste gas pipe, and threaded rings symmetrically threaded on the surface of the waste gas pipe. Two threaded rings are located at both ends of the cylinder cover, and a pipe groove is opened at the upper end of the cylinder cover. The waste gas pipe is slidably installed in the pipe groove. An annular groove is opened in the inner wall of the treatment cylinder, and a filter mechanism is set inside the treatment cylinder. The filter mechanism includes a fixing ring located inside the treatment cylinder. A first sliding groove is symmetrically opened on the side wall of the fixing ring, and a second sliding groove is opened in the inner wall of each of the two first sliding grooves. An inner groove is symmetrically opened in the inner wall of the fixing ring. This makes it easier to install and disassemble the activated carbon adsorption plate during use, and the connection method facilitates the replacement of the activated carbon adsorption plate.

[0004] However, existing equipment mainly relies on activated carbon stored inside the equipment for adsorption and filtration. Since the activated carbon is relatively stationary, the uniformity of contact between the upper activated carbon and the exhaust gas is affected during continuous airflow, resulting in resource waste when users replace the equipment uniformly. Utility Model Content

[0005] The purpose of this invention is to solve the problem of poor uniformity of activated carbon adsorption at different levels in the prior art, and to propose a biological fermentation feed exhaust gas treatment device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A biological fermentation feed exhaust gas treatment device, including a tank;

[0008] A filter box located inside the tank body;

[0009] Activated carbon particles filling the inside of the filter box;

[0010] The front and back of the tank are movably connected to a transmission rod via bearings. The inner end of the transmission rod passes through the tank and extends into its interior. A rotating wheel is fixedly connected to the inner end of the transmission rod. Sleeves are fixedly connected to both sides of the filter box. A sliding rod located inside the sleeve is fixedly connected to the inner side of the rotating wheel. The sliding rod is slidably connected to the sleeve. During the rotation of the rotating wheel, the sliding rod can squeeze the sleeve to make it carry the filter box and vibrate vertically. An air intake structure is provided at the bottom of the tank, which can transport the feed fermentation exhaust gas into the interior of the tank.

[0011] As a preferred technical solution of this application, the air intake structure includes a fan disposed on one side of the tank body, the output end of the fan is connected to a connecting pipe, and the side of the connecting pipe away from the fan is connected to the bottom of the tank body.

[0012] As a preferred technical solution of this application, the output shaft of the fan is fixedly connected to a shaft rod, and pulleys are fixedly connected to both ends of the shaft rod and the outer end of the transmission rod. The pulleys drive each other through a belt.

[0013] As a preferred technical solution of this application, both sides inside the filter box are movably connected to support rods via bearings, and guide plates are fixedly connected to the surface of the support rods. The guide plates can guide the activated carbon particles to distribute them evenly.

[0014] As a preferred technical solution of this application, the outer end of the support rod extends through to the outside of the filter box and is fixedly connected to a fork. Limiting rods are fixedly connected to both sides of the inner wall of the tank. The end of the limiting rod away from the tank extends into the interior of the fork and is slidably connected to the fork.

[0015] As a preferred technical solution of this application, the bottom of the filter box is fixedly connected to a connector, the bottom end of which extends into the interior of the connecting pipe and slides against the connecting pipe.

[0016] Compared with the prior art, this utility model provides a biological fermentation feed exhaust gas treatment device, which has the following beneficial effects:

[0017] 1. This bio-fermented feed exhaust gas treatment device achieves vertical oscillation of the filter box through the coordinated use of components such as transmission rods, rotating wheels, sleeve plates, and sliding rods. This solves the problem of poor uniformity of activated carbon adsorption in existing technologies. Through the oscillation of the filter box, activated carbon particles can be more evenly distributed in the filter box, thereby improving the treatment efficiency and effect of exhaust gas and ensuring that harmful substances in the exhaust gas are more effectively adsorbed and removed.

[0018] 2. This bio-fermented feed exhaust gas treatment device, by setting up a fan, connecting pipe and a connecting part at the bottom of the tank, can effectively transport the feed fermentation exhaust gas into the tank, providing the necessary conditions for subsequent exhaust gas treatment. The use of the fan ensures that the exhaust gas can continuously and stably enter the treatment device, improving the continuity and stability of the entire treatment process.

[0019] 3. This bio-fermented feed exhaust gas treatment device simplifies the operation process and reduces energy consumption by using components such as a fan output shaft, shaft, transmission rod, and pulley. Through the transmission of the pulley, the fan can drive the transmission rod to rotate while running, thereby causing the filter box to vibrate. No additional power source is required, which not only improves the overall efficiency of the equipment but also reduces operating costs.

[0020] 4. This bio-fermented feed exhaust gas treatment device, through the design of internal support rods and guide plates in the filter box, further improves the uniform distribution of activated carbon particles. The guide plates can guide the activated carbon particles to distribute them along a specific path, avoiding the accumulation and aggregation of particles in the filter box, which helps to extend the service life of activated carbon and improve the treatment effect of exhaust gas.

[0021] 5. This bio-fermented feed exhaust gas treatment device, through the design of the outer end of the support rod fork and the inner wall limit rod of the tank, ensures the stability and reliability of the filter box during the vibration process. The sliding connection between the fork and the limit rod limits the shaking range of the filter box, preventing equipment damage or the scattering of activated carbon particles due to excessive vibration, which helps to improve the durability and safety of the equipment.

[0022] 6. The exhaust gas treatment device for this bio-fermented feed features a sliding connection between the bottom insertion pipe and the connecting pipe of the filter box, which facilitates the disassembly and replacement of the filter box. When the activated carbon granules reach saturation or need to be replaced, the filter box can be easily removed and replaced simply by pulling the insertion pipe out of the connecting pipe, thus improving the ease of equipment maintenance and reducing maintenance costs.

An air intake structure 8 is provided at the bottom of tank 1. The air intake structure 8 can transport the feed fermentation exhaust gas into the interior of tank 1. Through the coordinated use of components such as transmission rod 4, rotating wheel 5, sleeve 6, and sliding rod 7, the vertical vibration of filter box 2 is achieved, solving the problem of poor uniformity of activated carbon adsorption in the prior art.
