Description

Technical Field

[0001] This utility model belongs to the technical field of waste cooking oil treatment equipment, specifically a filtration and fermentation device for waste food oil. Background Technology

[0002] By filtering and fermenting waste cooking oil, its environmental pollution can be effectively reduced. Untreated waste cooking oil, if discharged directly, will cause serious pollution to soil and water bodies. After being treated by this device, harmful substances in the waste cooking oil are decomposed, reducing its environmental impact.

[0003] The products of fermentation can be further utilized. For example, the short-chain fatty acids produced can be used to produce bioplastics or biofuels, realizing the resource recycling of waste cooking oil and improving resource utilization.

[0004] Currently, waste cooking oil is poured into the inlet of the filtration container and filtered through multiple layers of filter screens. First, larger impurities are intercepted by the outermost filter screen, and as the oil permeates, smaller impurities are removed by the inner filter screens. The filtered oil then enters the fermentation tank through the outlet.

[0005] In summary, the problem with the existing technology is that the filtration is not thorough. Although a filter screen is installed, it may not be able to completely and effectively filter out some tiny impurities. These residual impurities may have an adverse effect on the growth and metabolism of microorganisms during the fermentation process after entering the fermenter.

[0006] Therefore, this utility model designs a filtration and fermentation device for waste food oil, solving the technical problems existing in the prior art. Utility Model Content

[0021] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figure 1-3 The detailed description of the embodiments will clearly demonstrate this. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0022] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0023] Example 1: A filtration and fermentation device for waste food oil, comprising a filter box 1 and a stirring box 2, characterized in that: the filter box 1 is located at the upper end of the stirring box 2, a first filter box 3 is detachably connected inside the filter box 1, both the first filter box 3 and the filter box 1 are provided with filter holes 4, and the filter box 1 is provided with a feeding hopper 17.

[0024] The mixing tank 2 is rotatably connected to two sets of stirring paddles, which are driven by a power unit. The mixing tank 2 is equipped with a liquid outlet pipe 5 and an exhaust pipe 7. When a sealed fermentation environment is required, the exhaust pipe 7 is equipped with a one-way valve, a pressure gauge, and a pressure sensor. When the pressure inside the mixing tank 2 is too high, the one-way valve exhausts gas to the outside to ensure that the pressure inside the mixing tank 2 does not become too high, thereby avoiding risks.

[0025] The internal structure is equipped with a pH meter 6, a microbial delivery pipe 8 on the side wall, a heating block 9 and a cooling block 10 at the bottom, and a second filter box 11 located on the upper side of the stirring paddle is detachably connected to the inner side wall of the stirring box 2.

[0026] The filter box 1 is equipped with a squeezing device at its upper end.

[0027] As an optional embodiment of Example 1, the power unit includes two sets of electric motors 12 fixedly connected to the mixing tank 2. The two sets of mixing blades are driven by the electric motors 12 respectively, and the two sets of electric motors 12 are electrically connected to the controller.

[0028] As an optional embodiment of Example 1, the stirring paddle includes a stirring shaft 13 and stirring blades 14, and the stirring shaft 13 is provided with a plurality of stirring blades 14 in the circumferential direction.

[0029] As an optional embodiment of Example 1, the stirring blade 14 is arranged in an arc shape.

[0030] As an optional embodiment of Example 1, both the first filter box 3 and the second filter box 11 are provided with sealing rings.

[0031] As an optional embodiment of Example 1, the extrusion device includes a hydraulic telescopic rod 15, the extended end of which is provided with a pressure block 16 that cooperates with the first filter box 3, and the hydraulic telescopic rod 15 is electrically connected to the controller.

[0032] In practical applications, the extrusion equipment is either installed separately or integrated into the filter box 1 or the mixing box 2. This means the hydraulic telescopic rod 15 is either fixed to the wall or attached to the filter box 1 or the mixing box 2 via a connecting bracket. By driving the hydraulic telescopic rod 15, the pressure block 16 can be moved downwards. The maximum size of the pressure block 16 does not exceed the size of the first filter box 3.

[0033] During filtration, waste cooking oil (waste cooking grease) enters the first filter box 3 inside the filter box 1 through the feeding hopper 17. The hydraulic telescopic rod 15 is continuously driven, and the pressure block 16 compresses the waste cooking oil. The liquid grease enters the mixing box 2 through the filter holes 4 set in the mixing box 2 and the first filter box 3. The extrusion equipment can speed up the filtration of waste cooking oil, and impurities remain in the first filter box 3.

[0034] After filtration through the second filter box 11, the filtration quality is further improved, preventing excessive impurities from entering the mixing tank 2 and thus affecting the fermentation process.

[0035] The pH meter 6 and temperature sensor inside the mixing tank 2 can be used to monitor the inside of the mixing tank 2 in real time. Microorganisms are put into the filter box 1 through the microbial delivery pipe 8. The motor 12 drives the two sets of stirring paddles to rotate inside the mixing tank 2, so as to mix the fermentation microorganisms and the liquid evenly. The temperature detector detects the internal temperature abnormality, and the temperature inside the mixing tank 2 is controlled by the heating block 9 and the cooling block 10 set at the bottom.

[0036] If the pH value inside the mixing tank 2 is too high, the internal pH value can also be adjusted by adding medicine through the microbial dosing pipe 8;

[0037] Fermentation does not necessarily require a completely sealed space; this depends on the type of fermentation and the needs of the microorganisms. When conducting anaerobic fermentation, such as using anaerobic bacteria to treat waste cooking oil, it is necessary to create an oxygen-free, sealed environment as much as possible. This is because anaerobic bacteria can only grow and metabolize normally under anaerobic conditions. For aerobic fermentation, microorganisms need oxygen for respiration, thereby decomposing organic matter. For example, when using aerobic bacteria to treat waste cooking oil, air needs to be continuously supplied to the fermentation space.

[0038] When sealing is required, the hydraulic telescopic rod 15 is driven to place the pressure block 16 inside the first filter box 3, thus forming a sealed space. When sealing is not required, the hydraulic telescopic rod 15 is driven, and the pressure block 16 does not engage with the first filter box 3. This application is applicable to different fermentation conditions, has a simple structure, and is easy to adjust. The first filter box 3 and the second filter box 11 can be cleaned periodically.

[0039] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
