Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a centrifugal device for processing food waste with an anti-overflow function. Background Art

[0002] In the current food waste treatment industry, impurity removal pulping machines play an important role in the pretreatment of food waste. The impurity removal pulping machines widely used in the market currently mostly adopt the principle of combining mechanical pulping with centrifugal separation. The food waste is crushed and pulped by high-speed rotating blades, effectively removing large impurities and providing convenience for subsequent biodegradation or resource utilization. However, in this treatment process, the impurity removal pulping machine under the traditional design is not reasonable in the design of the entire exhaust structure. The position and structure of the exhaust port are often relatively arbitrary, and the odor characteristics generated by the food waste during the pulping process are not fully considered, including its physical properties (such as humidity, viscosity), temperature, component density and the aerodynamic effects caused by the rotation of the blades. Specifically, the high-speed rotating blades not only crush the material, but also strongly stir the gas inside the cavity, forming a significant positive pressure environment. When this positive pressure accumulates to a certain level, exceeding the negative pressure generated by the exhaust system through the exhaust port, the odor cannot be promptly and effectively drawn into the associated deodorization system. Consequently, the odor overflows, directly polluting the workshop air and adversely affecting the health of workers and the overall working environment. Therefore, there is an urgent need for a centrifugal food waste treatment device with an anti-overflow function. Utility Model Content

[0007] As described above, in a centrifugal device for processing food waste with an anti-overflow function, the junction of the return pipe and the air inlet bin forms an inlet end air port. When the gas discharged from the exhaust bin partially flows back to the inlet end air port through the return pipe, the wind pressure at the outlet end air port is reduced.

[0010] In the above-mentioned centrifugal device for processing food waste with an anti-overflow function, the caliber of the return pipe is consistent with the caliber of the second air duct.

[0011] In the above-mentioned centrifugal device for food processing with an anti-overflow function, the air outlet duct is bent to form an inclined section and a vertical section, and one end of the inclined section away from the vertical section is connected to the first air duct via a flange.

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1: Please refer to the attached Figure 1 To the attached Figure 2The present embodiment provides a centrifugal device for processing food waste with an anti-overflow function, comprising a pulping machine body 1, an exhaust mechanism 2 and a reflux mechanism 3 provided on the pulping machine body 1, the pulping machine body 1 comprising a processing chamber 11, an exhaust chamber 12 and an air intake chamber 13 connected to the processing chamber 11, the exhaust mechanism 2 comprising an exhaust main pipe 21 connected to the exhaust chamber 12, an end of the exhaust main pipe 21 away from the exhaust chamber 12 being connected to an external exhaust device, the reflux mechanism 3 comprising at least a reflux pipe 31, one end of the reflux pipe 31 being connected to the air intake chamber 13, an end of the reflux pipe 31 away from the air intake chamber 13 being connected to the exhaust main pipe 21 at the side of the reflux pipe 21, for diverting part of the gas transported in the exhaust main pipe 21 to the air intake chamber 13, so as to maintain a negative pressure in the processing chamber 11. The food waste treatment centrifugal equipment of this embodiment adopts the setting of adding a reflux mechanism 3 to the pulping machine body 1, and adopts the cooperation of the reflux mechanism 3 and the exhaust mechanism 2, so that when the external exhaust equipment extracts the waste gas generated in the processing chamber 11 through the exhaust main pipe 21, part of the waste gas will be diverted to the air inlet chamber 13 through the reflux pipe 31, and finally circulate back to the processing chamber 11 and be extracted again, thereby achieving the effect of maintaining a negative pressure state inside the processing chamber 11 during the entire exhaust process, and is not easily affected by the rotation of the blades inside the processing chamber 11, thereby avoiding the overflow of waste gas in the processing chamber. At the same time, the setting of the reflux mechanism is simple and easy to implement, and only a circulating reflux pipeline needs to be added to prevent the overflow of odor at a very low cost, thereby achieving a good deodorization effect.

[0021] The exhaust main pipe 21 includes a bifurcated pipe 211 and an outlet pipe 212. The bifurcated pipe 211 is provided with a first air duct 2111 and a second air duct 2112 arranged in a Y-shape. The junction of the first air duct 2111 and the second air duct 2112 forms an outlet air port 213. The outlet air duct 212 is connected to the first air duct 2111, and the return pipe 31 is connected to the second air duct 2112 to distribute the air volume passing through the outlet air port 213. The exhaust gas passing through the outlet air port 213 is split by the bifurcated pipe 211, and is respectively extracted through the exhaust main pipe 21 and returned to the air inlet bin 11 through the return pipe 31, thereby preventing air leakage from the pulping machine body 1.

[0022] Preferably, the diameters of the first air duct 2111 and the air outlet duct 212 are both larger than the diameter of the return duct 31, so that there is a difference between the exhaust air pressure and the return air pressure, ensuring the pressure reduction effect of the return mechanism 3, and the difference can be maintained during the exhaust process.

[0023] The junction of the return pipe 31 and the air inlet bin 13 forms an inlet end air port 311. When the gas discharged from the exhaust bin 12 partially flows back to the inlet end air port 311 through the return pipe 31, the wind pressure at the outlet end air port 213 is reduced. The setting of the return pipe 31 buffers the positive pressure generated in the processing bin 11 by circulating part of the exhaust gas, thereby reducing the wind pressure at the outlet end air port 213.

[0024] Preferably, in the optimization of the structure, the second air pipe 2112 is vertically arranged, the return pipe 31 is horizontally arranged, the return pipe 31 is connected to the second air pipe 2112 by being bent downward near one end of the second air pipe 2112, and the return pipe 31 is connected to the air inlet chamber 13 by being bent near one end of the air inlet chamber 13. Further, preferably, the return pipe 31 is connected to the air inlet chamber 13 by a flange near one end of the air inlet chamber 13, so that the connection of the return pipe 31 is more stable and firm, and air leakage is less likely to occur.

[0025] Preferably, in the optimization of the structure, the caliber of the return pipe 31 is consistent with the caliber of the second air pipe 2112.

[0026] Preferably, the air outlet pipe 212 is arranged by being bent to form an inclined section 2121 and a vertical section 2122, and the inclined section 2121 is connected to the first air pipe 2111 by a flange at one end away from the vertical section 2122, so that the connection of the air outlet pipe 212 and the first air pipe 2111 is more stable and firm, and air leakage is less likely to occur.

[0027] Preferably, in the optimization of the structure, the caliber of the inclined section 2121 and the vertical section 2122 is consistent with the caliber of the first air pipe 2111.

[0028] Preferably, in the optimization of the structure, the vertical section 2122 is arranged in parallel with the second air pipe 2112.

[0029] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
