Description

Technical Field

[0001] This invention relates to the field of carbon source preparation technology, and in particular to a carbon source preparation system for aquatic and kitchen waste. Background Technology

[0002] Carbon source refers to the source of carbon elements required for the growth, reproduction, and metabolic activities of microorganisms. Microbial carbon source preparation devices are mainly used to convert organic waste into carbon sources that can promote the growth and metabolism of microorganisms, thereby improving efficiency in biological treatment processes. The aquatic product processing industry (such as eel farms and seafood processing plants) generates a large amount of high-protein, high-oil waste (such as dead eels) every day. This type of waste is prone to decay and odor, and breeds bacteria. If it is directly landfilled or incinerated, it will not only waste organic resources, but also pollute the soil, water bodies, and atmosphere. Existing carbon source preparation systems have significant defects: the position accuracy of manually adjusted baffles is low, the oil layer is easy to mix with water, and the purity of recovered oil is poor; static stirring blades are difficult to adapt to changes in material viscosity; fixed-volume fermenters are difficult to adapt to fluctuating feed rates of waste, which can easily cause equipment to be unloaded or overloaded.

[0034] The working principle of this invention is as follows: In use, aquatic waste (such as dead eels) is sorted and impurities are removed, and mixed with household kitchen waste (after sorting and removing impurities such as plastic and glass) in a certain proportion. The mixture is then placed into the feed inlet 104. Then, the drive motor 111 is started. The drive motor 111 drives the drive gear 112 to rotate, the drive gear 112 drives the internal gear ring 113 to rotate, the internal gear ring 113 drives the conical gear 115 to rotate, and the conical gear 115 drives the feed inlet bevel gear 117 and the feed baffle 118 to rotate. The feed baffle 118 is opened, and the waste enters the housing 102. The waste is crushed by the crushing head 108. Then, water is added to the waste, and the waste is heated by the heating tube. The grease in the waste enters the upper layer.

[0035] Then, the lifting motor 133 is started. The lifting motor 133 drives the lifting gear 135 to rotate, which in turn drives the lifting gear 136 and the lifting nut 137 to rotate. The lifting nut 137 drives the oil baffle 131 and the oil baffle 142 to rise and fall via the lifting screw 132, adjusting the oil baffle 142 to below the grease layer. Then, the conical gear 115 continues to rotate until it meshes with the bevel gear 121. The bevel gear 121 drives the bevel gear 116 to rotate, which in turn drives the indexing gear 122 to rotate. The indexing gear 122 drives the indexing gear 123 to rotate. The lifting rod 129 and the second oil baffle 142 rotate 90 degrees, so that the first oil baffle 131 and the second oil baffle 142 are in a crossed state. The second oil baffle 142 is pulled by the spring 141 to a state where it is flush with the top surface of the first oil baffle 131, thus isolating the grease layer from the water. The inner gear ring 113 continues to drive the outer gear ring 114 to rotate. The outer gear ring 114 drives the valve plate gear 124 and the valve plate screw 125 to rotate. The valve plate screw 125 drives the valve plate 128 to rise, opening the opening of the oil outlet pipe 103. The second oil baffle 142 and the first oil baffle 131 continue to rise, and the grease on the upper layer of waste flows out through the oil outlet pipe 103, collecting the grease.

[0036] Then, the sealing plate 107 is rotated by the motor, and the waste enters the fermentation tank 201. The regulating motor 203 is started, which drives the regulating gear 1 205 to rotate. The regulating gear 1 205 drives the regulating gear 2 206 and the regulating nut 207 to rotate. The regulating nut 207 drives the regulating screw 208 and the regulating plate 212 to rise and fall, thereby adjusting the volume of the fermentation tank 201. While the regulating plate 212 moves, the stirring blade 213 is pulled by the rotating ring 215 and the limiting ring 214. The stirring blade 213 drives the slider 216 to move through the connecting rod 217. The slider 216 moves synchronously through connecting rod 1 218 and connecting rod 219, thereby causing multiple stirring blades 213 to move synchronously and changing the distance between the stirring blades 213, thus better stirring the material to facilitate the preparation of carbon source. During stirring, the stirring motor 209 is started, which drives the rotating plate 1 210 and the sliding rod 211 to rotate. The sliding rod 211 drives the rotating plate 3 221, slider 216, stirring blades 213, rotating ring 215 and rotating plate 220 to rotate, and the stirring blades 213 stir the material.

The lifting unit drives the oil baffle plate (131) to rise and fall. A sleeve (139) is fixedly installed on the oil baffle plate (131), and an end plate (140) is rotatably installed on the sleeve (139). The end plate (140) is connected to the oil baffle plate (142) via a spring (141). A valve plate gear (124) is fixedly installed on the lifting rod (129).

2. The carbon source preparation system for aquatic and kitchen waste as described in claim 1, characterized in that, The lifting rod (129) is a hollow structure. A hole is provided on the circumference of the bottom of the lifting rod (129). The hole at the bottom of the lifting rod (129) is connected to the oil baffle plate (142). The side wall at the top of the lifting rod (129) is connected to the water inlet pipe (138). The water inlet pipe (138) is connected to the water tank through a water pipe.

3. The carbon source preparation system for aquatic and kitchen waste as described in claim 2, characterized in that, The switching assembly includes a valve plate (128), which is an L-shaped plate. One end of the valve plate (128) is matched with the oil outlet pipe (103). The valve plate (128) is slidably mounted on the valve plate limit rod (127). A valve plate nut (126) is also fixedly mounted on the valve plate (128). The valve plate nut (126) and the valve plate screw (125) are threadedly mounted. A valve plate gear (124) is fixedly mounted at the end of the valve plate screw (125).

4. The carbon source preparation system for aquatic and kitchen waste as described in claim 3, characterized in that, The drive assembly includes an internal gear ring (113), which is coaxially and fixedly mounted with an external gear ring (114). The internal gear ring (113) drives the external gear ring (114) to rotate. The external gear ring (114) meshes with a valve plate gear (124). A conical tooth (115) is also fixedly mounted on the internal gear ring (113). The conical tooth (115) meshes with a feed inlet bevel gear (117). The conical tooth (115) also meshes with a bevel gear (121). The bevel gear 1 (121) and bevel gear 2 (116) are meshed and installed together. The bevel gear 2 (116) and index gear 1 (122) are coaxially fixed and installed together. The index gear 1 (122) and index gear 2 (123) are meshed and installed together. The valve plate nut (126) has a circular hole at its center. A slider is provided on the circular hole at the center of the valve plate nut (126). The slider on the circular hole at the center of the valve plate nut (126) is slidably installed along the length of the lifting rod (129).
