Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
Referring to fig. 1, fig. 2 and fig. 3, the present embodiment provides a three-phase separating device with a crushing and squeezing function for separating three phases of kitchen swill and separating solid garbage, waste water and grease. Wherein, this swill three-phase separator includes support body 1, letter sorting system, broken system, extrusion system and oil-water separation system, still includes the pan feeding system.
The frame body 1 is formed by splicing a plurality of square tubes, and the splicing mode can be welding, clamping, screwing and the like, and can be integrally formed. The bottom of support body 1 can set up structures such as pulley to support body 1 removes on ground. Simultaneously, the bottom of support body 1 also can set up limit structure, and limit structure can restrict support body 1 and remove subaerial, guarantees that support body 1 places stably in required fixed position. Certainly, the surface of the frame body 1 can be coated with oil-resistant and corrosion-resistant coating, so that the kitchen swill can be prevented from corroding the square pipe. The material of square pipe can be hard materials such as stainless steel or carbon steel, and its quantity is decided according to the overall structure of support body 1, can guarantee holistic fastness as far as possible. Of course, in this embodiment, a pulley and other components may be further disposed at the bottom of the frame body, so that the frame body 1 may slide on the ground as a whole.
In this embodiment, the feeding system is used for conveying the kitchen waste to be subjected to three-phase separation to the sorting system, and the feeding system comprises the elevator 4. The lifting machine 4 is installed on the frame body 1 and is used for lifting the garbage bin 5 used for containing the kitchen waste, so that the bin mouth of the garbage bin 5 faces the sorting system. The lifting machine 4 can adopt the existing lifting machine, and can directly lift the garbage can 5 from a low position to a high position so as to reduce the labor intensity of workers, and the garbage can 5 is rotated by a certain angle, for example, by 90 degrees, after the garbage can 5 is lifted to the high position, so that the kitchen swill/kitchen waste in the garbage can 5 is dumped into the sorting system.
The sorting system is used for sorting and separating the kitchen waste to remove hard foreign matters and obtain solid wet waste and liquid oil-water mixture. Wherein, letter sorting system includes letter sorting platform 2 and otter board 3. The sorting platform 2 is installed on the frame body 1 and used for containing kitchen swill. Sorting platform 2 can be funnel-shaped, and it can hold the kitchen swill/kitchen garbage of empting from garbage bin 5. The screen plate 3 is arranged on the sorting platform 2 and is used for solid-liquid separation of kitchen swill. In this embodiment, the mesh plate 3 is disposed at the lowest point of the sorting platform 2, so that the liquid in the kitchen swill/kitchen garbage can flow out, and the solid and part of the liquid adhered to the solid can be left on the sorting platform 2.
Referring to fig. 4 and 5, the crushing system is used for crushing the wet garbage to obtain a crushed product with a particle size meeting a predetermined particle size standard. Wherein the crushing system comprises a crushing roller 32, a crushing motor 33, a crushing shell 48, a flushing mechanism, a statistical mechanism and a crushing controller.
Both the upper and lower ends of the crushing shell 48 are open ends. The number of crushing rollers 32 is at least two and the crushing rollers 32 are rotatably mounted on the frame body 1, i.e. in the crushing shell 48. The two crushing rolls 32 are arranged in parallel in the axial direction, and the two ends of the two crushing rolls are aligned and separated by a preset rolling space. Wherein, wet rubbish enters from the same side of two crushing rollers 32, and leaves from the same side of two crushing rollers 32 after rolling through the preset rolling space. In this embodiment, the crushing roller 32 is rotatably mounted in the crushing shell 48, and the roller surface of the crushing roller 32 may be provided with a wear-resistant coating, which ensures a long-term use of the roller surface. In other embodiments, the roll surface of the crushing roller 32 may be provided with a convex structure, which can cut the meal or other solid composition in the kitchen waste, so that the kitchen waste can be sufficiently rolled and decomposed.
A crushing motor 33 is mounted on the frame body 1 and is used to drive the crushing roller 32 to rotate. The crushing motor 33 can be connected with the crushing roller 32 through a gear box, and can provide large torque for the crushing roller 32, so that the two crushing rollers 32 can sufficiently roll kitchen swill. Of course, the crushing motor 33 may also be arranged directly outside the crushing shell 48, with its output shaft inserted into the crushing shell 48 and coaxially connected with one of the crushing rollers 32. The working power of the crushing motor 33 can be selected according to the actual crushing requirements, i.e. when the crushing system is a small crushing device, the crushing motor 33 can be a low-power motor, and when the crushing system is a large crushing device, the crushing motor 33 needs to be replaced by a high-power motor.
The flushing mechanism comprises a plurality of spray heads 34, the spray heads 34 being mounted on the cartridge body 1. The spray head 34 is located on the same side of the two crushing rollers 32, and is used to spray washing water onto the roller surfaces of the crushing rollers 32. The washing mechanism can realize the cleaning function of the crushing roller 32, so that the roller surface can be kept clean, dirt generated in the long-term use process of the crushing roller 32 can be prevented from being accumulated, and the rolling efficiency of the crushing system is improved.
The statistical mechanism comprises a first detection component, a second detection component and a calculation module. The detection assembly I is used for detecting the first accumulated amount of the wet garbage entering the preset rolling space within a preset time period. The second detection assembly is used for detecting the second accumulation amount of the wet garbage leaving the preset rolling space in the preset time period. The calculation module is used for calculating the accumulated difference between the first accumulated amount and the second accumulated amount. Wherein the accumulated difference is the difference obtained by subtracting the accumulated amount two from the accumulated amount one. In this embodiment, the first detecting component can measure the garbage entering the rolling space through a device such as a flowmeter, and similarly, the second detecting component can also measure the rolled garbage through a device such as a flowmeter. Since there may be some dust adhering to the roll surface during rolling, the amount of dust remaining in the rolling space can be determined by determining the difference between the two measurements, and the crushing roll 32 can be cleaned using this information.
The crushing controller is configured to determine whether the cumulative difference is greater than a first preset crushing amount and not greater than a second preset crushing amount, and if so, drive the spray head 34 to spray the cleaning water. When the accumulated difference is between the first preset crushing amount and the second preset crushing amount, the situation that part of garbage is adhered to the roller surface at the moment is shown, and the roller surface needs to be cleaned, so that the crushing controller can drive the flushing mechanism to clean the roller surface. The crushing controller is also used for judging whether the cumulant difference is larger than a second preset crushing amount and not larger than a third preset crushing amount, if so, the spray head 34 is driven to spray cleaning water, and the rotating speed of the crushing motor 33 is increased according to the difference value of the cumulant difference and the third preset crushing amount. Wherein the increase in the rotational speed is positively correlated with the difference. When the accumulated difference is between the second preset crushing amount and the third preset crushing amount, the amount of the garbage adhered to the roller surface is very large, and the roller surface is required to be washed and the rolling speed is required to be increased so as to treat the garbage accumulated in the rolling space. The crushing controller is also used for judging whether the accumulated difference is larger than a preset crushing amount three, and if so, driving the crushing motor 33 to stop rotating. When the accumulated difference is larger than the preset crushing amount three, which indicates that the amount of garbage in the grinding space reaches the upper limit, if the crushing motor 33 continues to rotate, the crushing motor 33 and other equipment may be damaged, and thus the crushing controller stops the rotation of the crushing motor 33.
Referring to fig. 6-11, the extrusion system is used for extruding and dehydrating the crushed product, and obtaining extruded water and extruded material with water content reaching a preset dry humidity. The extrusion system comprises an extrusion shell 52, a screw rod 54, an extrusion motor 55, a locking mechanism and a water outlet pipe.
The crush can 52 is mounted on the frame 1, which in other embodiments may be integrally formed with the frame 1. The pressing chamber 53 is provided in the pressing shell 52, and the number of the pressing chambers 53 is at least two, and the pressing chambers 53 communicate with each other. The extrusion cavities 53 are connected together to form an extrusion channel, and the kitchen swill is extruded and dehydrated in the extrusion channel. The extruding shell 52 is also provided with a water outlet 56, and the number of the water outlets 56 is at least one. The squeezing cavity 53 near one end of the squeezing shell 52 is used for receiving kitchen swill, while the squeezing cavity 53 far away from one end of the squeezing shell 52 is used as a cavity for discharging liquid, and the liquid content in the mixture contained in the squeezing cavity is the highest, so that an oil scraping source can be provided for the follow-up process.
In this embodiment, the crush can 52 includes a housing 69 and a screen 70. The housing 69 includes a feed housing 71, a baffle 72, and a sump housing 73. The top of the feeding shell 71 is provided with a feeding hole for receiving kitchen swill, and the bottom of the feeding shell 71 is higher than the bottom of the water tank shell 73. The top opening of the feeding shell 71 is relatively large, and can be used for receiving sufficient kitchen swill. The partition 72 is disposed between the feeding shell 71 and the water tank shell 73, and has a plurality of through holes 74 communicating the feeding shell 71 and the water tank shell 73. Thus, the liquid in the feeding housing 71 can also directly flow into the water tank housing 73 through the through hole 74 for collection. The partition 72 is further provided with a discharge port 75, and the discharge port 75 is used for conveying kitchen swill to the sieve tube 70 described later. The sieve tube 70 is positioned in the water tank shell 73, and the side wall of the sieve tube is provided with a plurality of water permeable holes which can allow the liquid positioned in the sieve tube 70 to flow out. The screen 70 has one end capped at the outlet 75 and the other end capped at the end of the circular channel 60 adjacent to the sump housing 73. Thus, the kitchen waste in the feeding shell 71 can enter the sieve tube 70 through the discharge hole 75 and is located in the extrusion chamber 53 in the sieve tube 70. Wherein the screw rod 54 is arranged in the sieve tube 70, and the locking shell 57 and the end of the water tank shell 73 far away from the partition plate 72 are arranged.
A screw 54 is rotatably mounted in the extrusion housing 52 and extends through all of the extrusion chambers 53.
