Description

Technical Field

[0001] The invention belongs to the technical field of slaughterhouse waste treatment, and relates to a waste treatment device, in particular to a slaughterhouse waste mixing treatment reaction device. Background Art

[0002] Slaughterhouse waste must be treated harmlessly and recycled, and direct landfilling or incineration is prohibited. However, the industry faces three major pain points: complex composition (the coexistence of blood, feathers, bones, and fat), high pathogen risk (for example, the African swine fever virus can survive for 30 days at room temperature), and poor equipment adaptability (traditional equipment has a failure rate of over 30%). These factors lead to low processing efficiency and high costs, resulting in an annual loss of over 5 million tons of usable resources, urgently requiring technological innovation and breakthroughs.

[0003] Existing technologies suffer from deficiencies such as substandard key parameters (mixing uniformity ≤ 70%, bone fragmentation particle size > 20mm) and excessively long processing cycles (pretreatment > 1 hour), failing to meet the demand for efficient resource utilization. Faced with a massive market of over 20,000 slaughterhouses nationwide and 30 million tons of waste annually, there is an urgent need to develop an integrated device that combines multiple mechanical fields (high shear cutting + ultrasonic emulsification + microwave sterilization) with intelligent control. This device can overcome the complexity of ingredients, achieve the core goals of high pathogen inactivation rates and high resource conversion returns, and fill the technological gap in the industry.

[0004] Therefore, we propose a mixed treatment reaction device for slaughterhouse waste. Summary of the Invention

During the lifting process, the primary spiral body can filter water synchronously, and discharge the free liquid in the material from several primary filtrate pipes and discharge it into one of the premixing mechanisms.

The steam generated by the mixing steam tank can enter the sealed base frame through the connecting hole to heat and insulate the premixing tank.

[0024] Compared with the existing technology, the slaughterhouse waste mixed treatment reaction device has the following advantages: Efficient and thorough grading: The three-stage crushing system adapts to wastes of different hardness / sizes, ensuring a small final particle size to meet the requirements of the maturation reaction; Vibration screening + spiral filtrate simultaneously achieves solid-liquid separation, and waste liquid is centrally recovered and processed to avoid equipment clogging; Premixing dual-channel design: solid and liquid waste are premixed separately, and enzyme preparations / acid-base regulators are added in a targeted manner to significantly improve the degradation efficiency of insoluble substances.

[0025] Thermal energy cycle saves significant energy: Steam direct injection mixing roller: high-temperature steam directly contacts the material through the outlet holes of the mixing steam roller, improving heat transfer efficiency; Cascade utilization of waste gas: the residual steam generated by aging is used to preheat the materials in the screw elevator through the steam guide pipe, thus reducing the total steam consumption; Premixing tank steam insulation: The hot steam from the mixing steam tank heats the premixing mechanism through the connecting hole to maintain the mixing temperature.

[0026] Modular maintenance is convenient: quick-open maintenance design: the flap of the slitting mechanism is opened and closed by an electric push rod with one button, supporting rapid replacement of the knife roller; the arc-shaped hole of the strip cutting mechanism allows the saw blade group to be removed for maintenance as a whole; sealing and leak-proof guarantee: the premixing tank discharge sealing flap is hydraulically controlled, and zero leakage is achieved during mixing; the rotating steam adding joint is matched with the limit connecting rod to ensure the safety of high-temperature steam transportation.

[0027] The steam curing stage maintains a high temperature and high pressure environment to completely kill pathogens; Full recycling of waste liquid: filtrate and waste liquid are uniformly collected into the premixing mechanism for treatment, achieving zero wastewater discharge.

[0056] The material premixed by the premixing mechanism 7 is injected into the mixing steam tank 69 through the connecting hole, and the steam generated by the external steam generating equipment enters the hollow shaft of the mixing steam roller 67 by rotating the steam adding joint 73. The steam is ejected from the air outlet of the mixing steam roller 67 and directly contacts the material.

During mixing, the discharge sealing flap 63 is closed. During discharging, the flap electric push rod 64 drives the discharge sealing flap 63 to open, and the material falls directly into the mixing steam tank 69 from the connecting hole through the sealing base frame 55. The steam generated by the mixing steam tank 69 can enter the sealing base frame 55 through the connecting hole to heat and keep the premixing tank 60 warm.

[0059] Working principle of the present invention: Step 1: Waste sorting The output shaft of the sorting motor 17 drives the rotating mounting shaft to rotate, thereby driving the vibrating eccentric block 14 to rotate, and then driving the sorting box 15 to vibrate on several groups of vibrating springs 16, pouring the slaughterhouse waste into the sorting box 15, and the large material discharge screen 13 slides the larger waste (such as bones and even large pieces of carcass) along the screen surface to discharge it to the side end; the small material discharge screen 12 slides the smaller waste (minced meat, offal) along the screen surface to discharge it to the side end, and the extremely small waste mixed with the waste liquid flows into the waste liquid discharge hopper 18 through the screen holes for collection.

[0060] Step 2: Slice the large material Larger waste falls into the upper end of the horizontal feed roller group 21 of the feeding area 20. According to the specific size of the larger waste, the two lifting electric push rods 29 drive the lifting connecting rod 24 to move up and down, thereby driving the lifting frame 23 to move up and down, and then adjusting the distance between the inclined feed roller group 22 and the horizontal feed roller group 21, that is, adjusting the size of the trumpet shape between the inclined feed roller group 22 and the horizontal feed roller group 21, so as to ensure that the inclined feed roller group 22 and the horizontal feed roller group 21 can stably clamp and transport larger waste. This process can be adjusted manually or by designing visual sensors. After the device or infrared sensor determines the size of the larger waste, it automatically adjusts, the output shaft of the horizontal feeding motor drives the rotating shaft of the horizontal feeding roller group 21 to rotate slowly, and the output shaft of the inclined feeding motor drives the rotating shaft of the inclined feeding roller group 22 to rotate slowly, and the larger waste is transported to the arc-shaped rotary blade plate 30, and the output shaft of the knife roller motor drives the rotating shaft of the rotary slicing knife roller 25 to rotate rapidly, and the rotary slicing knife roller 25 contacts the arc-shaped rotary blade plate 30, and cooperates with each other to slice the larger waste, and the large slices after slicing fall out from the bottom between the feeding area 20 and the knife roller area.

[0061] Step 3: Slice into thin strips The positioning electric push rod 35 is extended and retracted, pushing the articulated frame 33 to rotate around the rotating seat 34, and the saw blade mounting shaft 36 slides along the avoidance arc hole 38 to change the inclination angle of the saw blade group and adjust the distance between the slitting saw blade 32 and the inner wall of the material guide slicing bin 31 to meet the cutting size requirements; the output shaft of the slicing motor 37 drives the saw blade mounting shaft 36 to rotate at high speed between one end of the two articulated frames 33, that is, drives the slitting saw blade 32 to rotate at high speed, and the thin slice material output by the slicing mechanism 3 falls into the top opening of the material guide slicing bin 31. After the material falls into the inside of the material guide slicing bin 31, the high-speed rotating slicing saw blade 32 cuts the thin slice into parallel strips with smooth incisions and no burrs. The strip material falls from the bottom of the material guide slicing bin 31 to the inside of the crushing mechanism 5 below.

[0062] Step 4: Crush the pieces The strip materials cut by the strip cutting mechanism 4 fall from the bottom of the material guide and slicing bin 31 to the inside of the crushing hopper 49 below. The output shaft of the crushing motor 48 drives the rotating shaft of the crushing spiral roller to rotate. The crushing spiral roller conveys the cut strip materials to the crushing cutter head tube 50. The crushing cutter head tube 50 cuts the strip materials into pieces and extrude them. The speed of the crushing motor 48 is adjusted by the electrical control box 47.

[0063] Step 5: Material lifting and filtrate recovery Smaller wastes fall into the primary feed hopper 42 located in the small material discharge area 19 and enter the primary spiral body 41 from the feed end. The primary spiral body 41 lifts the smaller wastes to the discharge end and conveys them from the primary discharge hopper 40 to the inside of another premixing mechanism 7. During the lifting process, the primary spiral body 41 can simultaneously filter water and discharge the free liquid in the material from several primary filtrate pipes 43 and discharge it into one of the premixing mechanisms 7. The shredded waste from the pulverizing mechanism 5 falls into the secondary feed hopper 51 and enters the secondary spiral body 52 from the feed end. The secondary spiral body 52 lifts the shredded waste to the discharge end and conveys it to another premixing mechanism 7 from the secondary discharge hopper 53. During the lifting process, the secondary spiral body 52 can filter water simultaneously, discharging the free liquid in the material from several secondary filtrate pipes 54 and discharging it into one of the premixing mechanisms 7. Step 6: Premixing The injection pipe 61 of one of the premixing mechanisms 7 is connected to the primary filtrate pipe 43, the secondary filtrate pipe 54 and the waste liquid outlet hopper 18 through a water pipe. The liquid waste is injected into the premixing tank 60 of one of the premixing mechanisms 7 through the injection pipe 61 by a liquid adding pump. The material guide flow valve 45 is used to control the flow rate. The injection pipe 61 of the other premixing mechanism 7 is connected to the primary discharge hopper 40 and the secondary discharge hopper 53 through a material guide pipe, and the solid waste is injected into the premixing tank 60 of the other premixing mechanism 7. The auxiliary material addition tank 44 is connected to both premixing mechanisms 7 through a water pipe and a liquid adding pump. The liquid auxiliary materials are injected into the two premixing tanks 60 through the injection pipe 61, and the output shaft of the premixing motor 57 drives the premixing main shaft 58 to rotate, thereby driving the two stirring frames 62 to rotate synchronously in opposite directions through the driving transmission gear pair 59, stirring and mixing the materials inside the premixing tank 60. During mixing, the discharge sealing flap 63 is closed. During discharging, the flap electric push rod 64 drives the discharge sealing flap 63 to open, and the material falls directly into the mixing steam tank 69 from the connecting hole through the sealing base frame 55. The steam generated by the mixing steam tank 69 can enter the sealing base frame 55 through the connecting hole to heat and keep the premixing tank 60 warm.

[0064] Step 7: Cook and Mix The material premixed by the premixing mechanism 7 is injected into the mixing steam tank 69 through the connecting hole, and the steam generated by the external steam generating equipment enters the hollow shaft of the mixing steam roller 67 by rotating the steam adding joint 73. The steam is ejected from the air outlet of the mixing steam roller 67 and directly contacts the material. The steam is continuously introduced into the mixing steam tank 69 to increase the temperature and mature the internal material. The mature mixing motor 70 drives the two mixing steam rollers 67 to rotate synchronously in the opposite direction by driving the transmission gear pair 71, and promotes the high shear mixing of the material in the gap between the two mixing steam rollers 67, and performs simultaneous steam injection and stirring and mature mixing. The pathogenic microorganisms are killed by the high temperature of the steam, and at the same time, the material and the auxiliary materials undergo mixing reactions such as hydrolysis and lipolysis under high temperature and high pressure to degrade large molecular organic matter. The evaporated gas is transported to the primary screw elevator 9 and the secondary screw elevator 6 through the exhaust pipe 72 and the steam guide pipe to preheat the front-end material. After the reaction is completed, the discharge valve is opened and the mature material is discharged into the downstream process.

[0065] Step 9: Discharging After the aging is completed, the discharge valve on the side of the mixed steam tank 69 is opened; the degraded material is discharged into the downstream processing link (such as drying or fermentation).

[0066] In summary, the classification process is efficient and thorough: the three-stage comminution system (slicing → cutting → crushing) is suitable for wastes of different hardness / sizes, ensuring the final particle size is ≤5mm, meeting the requirements of the maturation reaction; Vibration screening + spiral filtrate simultaneously achieves solid-liquid separation, and waste liquid is centrally recovered and processed to avoid equipment clogging; Premixing dual-channel design: solid and liquid waste are premixed separately, and enzyme preparations / acid-base regulators are added in a targeted manner to significantly improve the degradation efficiency of insoluble substances (such as hair).

[0067] Intelligent adjustment and strong adaptability: Electric distance adjustment of the slicing mechanism: The horizontal / inclined roller spacing is dynamically adjusted by lifting the electric push rod 29 to accommodate the size differences from cattle bones to poultry; Adjustable strip cutting angle: The electric push rod 35 is adjusted to control the inclination angle and gap of the slitting saw blade 32, accurately controlling the specifications of the strip material; Frequency conversion control of the crushing motor: the electric control box 47 adjusts the speed of the crushing motor 48 to adapt to different material hardness.

[0068] Thermal energy cycle saves significant energy: Steam direct injection mixing roller: high-temperature steam directly contacts the material through the outlet holes of the mixing steam roller 67, improving heat transfer efficiency; Cascade utilization of waste gas: the residual steam generated by aging is used to preheat the materials in the screw elevator through the steam guide pipe, thus reducing the total steam consumption; Premixing tank steam insulation: The hot steam from the mixing steam tank 69 heats the premixing mechanism 7 through the connecting hole to maintain the mixing temperature.

[0069] Modular maintenance is convenient: quick-open maintenance design: the flap 26 of the slicing mechanism is opened and closed by the flip-up electric push rod 27 with one button, supporting rapid replacement of the knife roller; the arc-shaped hole 38 of the slitting mechanism avoids the saw blade group and allows for maintenance; sealing and leak-proof guarantee: the premixing tank discharge sealing flap 63 is hydraulically controlled, and zero leakage is achieved during mixing; the rotating steam adding joint 73 cooperates with the limit connecting rod 74 to ensure the safety of high-temperature steam transportation.

[0070] The high-pressure and high-temperature hot steam from the mixed steam tank 69 can inactivate pathogenic microorganisms, and the high-temperature and high-pressure environment maintained during the steam maturation stage can completely kill pathogens; Improved organic matter degradation rate: The enzyme preparation fully penetrates in the premixing stage, combined with high-temperature hydrolysis, to increase the efficiency of fat / protein degradation; Full recycling of waste liquid: The filtrate and waste liquid are uniformly collected in the premixing mechanism for treatment, achieving zero wastewater discharge.

[0071] Powerful processing capacity, continuous design, and improved equipment efficiency; reduced operating costs: thermal energy circulation + automated control reduces manual intervention and overall energy consumption; product resource utilization: the output meets the standards of organic fertilizer raw materials, achieving high-value waste conversion.

[0072] The four-fold design of graded crushing, intelligent control, thermal energy circulation and module maintenance solves the problems of uneven particle size, high energy consumption and pathogen residue in the treatment of slaughtering waste, and achieves high efficiency, economy and environmental compliance.
