Description

Technical Field

[0001] This utility model belongs to the field of corn fermentation tank discharge technology, specifically relating to a novel discharge guiding device for corn fermentation tanks. Background Technology

[0002] In the corn deep processing and bio-fermentation industry, the discharge guidance of high-solids-content corn fermentation materials has always been a technical bottleneck restricting production efficiency. Traditional guidance devices adopt a fixed tilt angle design, which generally suffers from problems such as material flow stagnation and severe sidewall adhesion when processing corn fermentation materials with a solid content exceeding 30% and a viscosity greater than 5000 cP. In existing technologies, gravity-fed self-flowing guide channels lack auxiliary power, resulting in the formation of a stagnant layer of high-viscosity materials in the tank; mechanical scraper-type guide devices can improve flowability, but have drawbacks such as complex structure and easy contamination of materials. Especially when processing corn materials that have been fermented for more than 72 hours, their unique non-Newtonian fluid characteristics will exhibit significant thixotropy with changes in shear rate, and the rigid structure of conventional guide devices cannot adapt to this rheological characteristic change. Therefore, this utility model proposes a novel discharge guidance device for corn fermentation tanks to solve the above-mentioned technical problems. Utility Model Content

[0003] The purpose of this invention is to provide a novel discharge guiding device for corn fermentation tanks, which can solve the above-mentioned technical problems.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] This utility model provides a novel discharge guiding device for a corn fermentation tank, including a base frame and a guide frame set above the base frame. The bottom surface of the guide frame is provided with a movable support mechanism connected to the base frame. A support platform located on the bottom surface of the guide frame is installed on the base frame. A pulse gas distribution mechanism is provided on the support platform. A controller for controlling the pulse gas distribution mechanism is installed on the support platform.

[0006] The guide frame includes an expanding part and a contracting part, and multiple air nozzles are installed on the side plates of the expanding part and the contracting part;

[0007] The pulse gas distribution mechanism includes a pressure-increasing buffer tank and a pulse valve. A distribution pipe is provided above the support platform. The distribution pipe is cross-shaped and its four ends are respectively connected to two first gas diffusers, a second gas diffuser, and the pulse valve. The pulse valve, the two first gas diffusers, and the second gas diffuser are all mounted on the support platform. A connecting pipe is installed at the inlet end of the pulse valve and is connected to the pressure-increasing buffer tank. The pressure-increasing buffer tank is mounted on the support platform.

[0008] Preferably, the pulse air distribution mechanism further includes two sets of first air distribution pipes and two sets of second air distribution pipes. The upper sides of the two sets of first air distribution pipes are respectively connected to the air nozzles on the two side plates of the expansion portion, and the lower sides of the two sets of first air distribution pipes are respectively installed on two first air diffusers.

[0009] Preferably, the upper sides of the two sets of second air distribution pipes are connected to the air nozzles on the two side plates corresponding to the contraction section, and the lower sides of the two sets of second air distribution pipes are installed on the second air diffuser.

[0010] Preferably, the movable support mechanism includes a support frame, a through pin shaft, and a power device. The support frame is detachably installed on one side of the base frame. Two perforated ear plates are fixed at both ends on one side of the bottom surface of the expanded portion of the guide frame. The two perforated ear plates are located between the upper side of the support frame. The through pin shaft passes through the upper side of the support frame and forms a rotatable connection with the two perforated ear plates.

[0011] Preferably, the upper side of the power device is rotatably mounted on the bottom surface of the guide frame contraction section via a hinge seat, and the lower side of the power device is rotatably mounted on the base frame via a hinge seat.

[0012] Preferably, the adjustable angle range of the guide frame by the movable support mechanism is 30-60°.

[0013] Preferably, the pressure buffer tank is connected to the output end of an external air compressor via an installed input pipe.

[0014] The beneficial effects are:

[0015] This invention utilizes the coordinated operation of the guide frame, the movable support mechanism, and the pulse gas distribution mechanism. The first and second gas distribution pipes of the pulse gas distribution mechanism respectively apply pulsed airflow to the side walls of the expanding and contracting parts of the guide frame, effectively enhancing the flowability of the corn fermentation material.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figure 1-3 As shown, a novel discharge guiding device for a corn fermentation tank includes a base frame 1 and a guide frame 3 set above the base frame 1. The bottom surface of the guide frame 3 is provided with a movable support mechanism connected to the base frame 1. A support platform 6 located on the bottom surface of the guide frame 3 is installed on the base frame 1. A pulse gas distribution mechanism is provided on the support platform 6. A controller 12 for controlling the pulse gas distribution mechanism is installed on the support platform 6.

[0023] The flow guide frame 3 includes an expanding part 31 and a contracting part 32. The inner angle of the expanding part 31 is 55° and the inner angle of the contracting part 32 is 35°. Multiple air nozzles 33 are installed on the side plates of the expanding part 31 and the contracting part 32. The flow guide frame 3 is made of stainless steel welded as a whole, and the inner surface is plasma sprayed with an Al2O3 coating (thickness 50μm).

[0024] The pulse gas distribution mechanism includes a pressure-concentrating buffer tank 7 and a pulse valve 8. A distribution pipe 9 is provided above the support platform 6. The distribution pipe 9 is cross-shaped, and its four ends are respectively connected to two first gas diffusers 10, a second gas diffuser 11, and the pulse valve 8. The pulse valve 8, the two first gas diffusers 10, and the second gas diffuser 11 are all installed on the support platform 6. A connecting pipe is installed at the inlet end of the pulse valve 8, and the connecting pipe is connected to the pressure-concentrating buffer tank 7. The pressure-concentrating buffer tank 7 is installed on the support platform 6. The pulse frequency of the pulse valve 8 is 0.5-2Hz.

[0025] As an optional implementation, the pulse gas distribution mechanism further includes two sets of first gas distribution pipes 10a and two sets of second gas distribution pipes 11a. The upper sides of the two sets of first gas distribution pipes 10a are respectively connected to the air nozzles 33 on the two side plates of the expansion section 31, and the lower sides of the two sets of first gas distribution pipes 10a are respectively installed on two first gas diffusers 10. In this way, the first gas distribution pipes 10a can collect corn fermentation material while using pulse airflow to blow and gather the material, ensuring the smooth flow of corn fermentation material from the expansion section 31 to the contraction section 32.

[0026] Furthermore, the upper sides of the two sets of second air distribution pipes 11a are respectively connected to the air nozzles 33 on the two side plates corresponding to the contraction section 32, and the lower sides of the two sets of second air distribution pipes 11a are installed on the second air diffuser 11. In this way, the second air distribution pipes 11a can be blown by pulse airflow to ensure the smooth flow of corn fermentation material in the contraction section 32.

[0027] See attached document Figure 2 and attached Figure 3 The movable support mechanism includes a support frame 2, a through pin 4, and a power device 5. The support frame 2 is detachably installed on one side of the base frame 1. Two perforated ear plates 34 are fixed at both ends of the bottom side of the expansion portion 31 of the guide frame 3. The two perforated ear plates 34 are located between the upper sides of the support frame 2. The through pin 4 passes through the upper side of the support frame 2 and forms a rotatable connection with the two perforated ear plates 34. A pin is threaded through the free end of the through pin 4, so that the through pin 4 can prevent it from falling out while providing a rotation fulcrum for the guide frame 3.

[0028] Furthermore, the upper side of the power device 5 is rotatably mounted on the bottom surface of the contraction part 32 of the guide frame 3 via a hinge seat, and the lower side of the power device 5 is rotatably mounted on the base frame 1 via a hinge seat. The power device 5 is an electric push rod or a hydraulic push rod, thereby realizing the angle adjustment of the guide frame 3 through push-pull movement.

[0029] Furthermore, the angle of the guide frame 3 is adjustable from 30 to 60° by the movable support mechanism, so that the tilt angle can be adjusted in real time according to the discharge requirements of the corn fermentation tank to ensure the smooth flow of the fermented material.

[0030] Furthermore, the pressure-reducing buffer tank 7 is connected to the output end of an external air compressor via an installed input pipe. The output airflow pressure range of the air compressor is 0.2-0.5MPa. In this way, through the cooperation of the air compressor and the buffer tank, the air compressor is protected from overload when the pulse valve 8 is frequently opened and closed, while maintaining stable air pressure after the pulse.

[0031] Using the above structure, the intermittent high-pressure airflow generated by the pulse air distribution mechanism acts on the air nozzles 33 of the expanding part 31 and the contracting part 32 of the guide frame 3 through the first air distribution pipe 10a and the second air distribution pipe 11a, respectively, forming periodic airflow shock waves. This effectively destroys the adhesion layer formed on the inner wall of the guide frame 3 by the high-solids content corn fermentation material. At the same time, the movable support mechanism, through the precise pushing and pulling of the power device 5, allows the guide frame 3 to achieve stepless angle adjustment within the range of 30-60°. This dynamic adjustment mechanism can change the guide angle in real time according to the material viscosity, combined with the working pressure of 0.2-0.5MPa and the pulse airflow of 0.5-2Hz. The pulse frequency forms a composite flow guiding mode of "airflow impact + gravity assistance", which is particularly suitable for corn fermentation materials with high solid content and viscosity. It can improve the flow guiding efficiency by more than 40% and control the residual amount to within 5%. The 55° tilt angle of the expansion section 31, combined with the 0.3MPa pulse airflow, can achieve the initial dispersion of materials. The 35° tilt angle of the contraction section 32, combined with the 0.4MPa pulse airflow, ensures the accelerated discharge of materials. The entire system achieves the optimal matching of airflow parameters and mechanical angles through the coordinated control of the controller 12, which completely solves the problems of flow stagnation and wall adhesion when traditional flow guiding devices are used to process high viscosity fermentation materials.
