Description

Technical Field

[0001] The utility model relates to the technical field of livestock and poultry manure treatment, in particular to an organic waste separation device. Background Art

[0002] With the large-scale development of the livestock farming industry, livestock farms generate large amounts of organic wastewater mixed with organic matter (feces, fertilizer, feed, feathers, etc.) during production. Currently, the comprehensive utilization rate of these organic wastes in livestock farming remains low. If these organic wastes are not effectively treated and recycled, they will not only result in the waste of usable organic waste but also cause serious environmental pollution.

[0003] In the existing organic waste separation devices in the field of livestock and poultry manure treatment technology, most of them automatically separate the wastewater and waste residue of organic waste by gravity through a filter. However, the degree of mixing of the liquid and residue in the organic waste is high, and it is difficult to separate them completely by gravity or other single filtration methods alone. Therefore, the separation of organic waste and organic wastewater is not thorough enough and the separation effect is poor. The existing organic waste separation devices for livestock and poultry manure are difficult to achieve efficient separation in the separation process, which makes it difficult to fully utilize the available resources.

[0004] Therefore, it is of great significance to obtain an organic waste separation device that can improve the solid-liquid separation ability of organic waste such as poultry and livestock manure. Utility Model Content

[0005] The main purpose of the utility model is to provide an organic waste separation device, aiming to solve the problems of insufficient separation capacity and low utilization rate of organic waste from livestock and poultry manure.

[0028] The present utility model proposes an organic waste separation device 1000, comprising: a shell 100; a rolling screen assembly 200, which is arranged inside the shell 100 along the central axis of the shell 100; a push rod assembly 300, which is arranged inside the rolling screen assembly 200 along the axial direction of the rolling screen assembly 200, and the push rod assembly 300 is connected to the rolling screen assembly 200; a vibrating screen assembly 400, which is arranged inside the shell 100 below the rolling screen assembly 200; and a reaction bed assembly 500, which is arranged inside the shell 100 below the vertical projection of the vibrating screen assembly 400, and at least one end of the reaction bed assembly 500 is connected to the inner wall of the shell 100.

[0029] In one embodiment, Figure 1 As shown, the organic waste separation device 1000 includes a shell 100, a rolling screen assembly 200, a push rod assembly 300, a vibrating screen assembly 400, and a reaction bed assembly 500. A volume space is formed inside the shell 100. The rolling screen assembly 200, the push rod assembly 300, the vibrating screen assembly 400, and the reaction bed assembly 500 are all arranged in the volume space. The rolling screen assembly 200 is located above the vertical projection of the vibrating screen assembly 400. The vibrating screen assembly 400 is located above the vertical projection of the reaction bed assembly 500. The rolling screen assembly 200 has a cavity. The push rod assembly 300 is arranged in the cavity of the rolling screen assembly 200. The push rod assembly 300 can move the rolling screen assembly 200 and the rolling screen assembly 200. 0 abuts against the inner wall of the cavity, the push rod assembly 300 can move relative to the rolling screen assembly 200 to push the organic waste. During operation, the operator passes the organic waste into the shell 100, and the organic waste is first screened by the rolling screen assembly 200 to perform a preliminary screening, and the liquid and solid in the organic waste are initially separated to obtain liquid and viscous residue. The viscous residue is then pushed out of the cavity of the rolling screen assembly 200 by the push rod assembly 300 and falls onto the vibrating screen assembly 400. The vibrating screen assembly 400 separates the viscous residue again and separates the viscous residue into liquid and dry residue. The dry residue and liquid are converted through the reaction bed assembly 500 to obtain solid fertilizer and liquid fertilizer respectively after conversion.

[0030] In detail, the rolling screen assembly 200 is a shaftless rolling screen. The rolling screen assembly 200 includes a screen frame, a motor, and a transmission wheel. The motor is arranged on the lower side of the two ends of the central axis of the drum and is abutted against the screen frame through the transmission wheel. The transmission wheel is abutted against the two ends of the central axis of the screen frame. The screen frame is rotated by the transmission wheel driven by the motor. The screen frame is provided with an adjustable inclination angle to facilitate further separation or utilization of the viscous material residue after solid-liquid separation.

[0031] like Figure 2As shown, the rolling screen assembly 200 is located vertically above the vibrating screen assembly 400, and the axial length direction of the rolling screen assembly 200 is perpendicular to the vibrating screen assembly 400, which is beneficial to saving device space.

[0032] In another embodiment, the number of vibrating screen assemblies 400 can be multiple, and the multiple vibrating screen assemblies 400 are arranged at an angle to each other. It can be understood that the filtration mesh numbers of the multiple vibrating screen assemblies 400 can be adjusted according to needs. In this embodiment, the filtration mesh numbers of the multiple vibrating screen assemblies 400 gradually increase from top to bottom in spatial position (that is, the filtration hole diameters of the multiple vibrating screen assemblies 400 are different, and the filtration hole diameters of the vibrating screen assemblies 400 from top to bottom become smaller and smaller), and the multiple vibrating screen assemblies 400 are arranged in a zigzag shape.

[0033] In one embodiment, the shell 100 further includes a feeding device 600 . The feeding device 600 is disposed above the shell 100 and is disposed above the reaction bed assembly 500 .

[0034] In detail, in the present invention, the feeding device 600 includes a feeding pipe group 610 and a cover. The cover is arranged on the end of the feeding pipe group 610 away from the shell 100, and the cover is rotatably connected to the feeding pipe group 610, so that the operator can achieve the airtight effect of the volume space inside the shell 100 by tightening the cover or loosen the cover to feed the shell 100.

[0035] It is understandable that the connection between the cover and the feeding pipe assembly 610 can also be an axial rotation connection or a plug-in connection.

[0036] In one embodiment, the feeding device 600 further includes a feeding pipe group 610 , which is disposed above the shell 100 and has a liquid sealing structure 611 , which is located at one end of the feeding pipe group 610 inside the shell 100 .

[0037] It can be understood that the feeding device 600 feeds microbial agents into the internal space of the shell 100 through the feeding pipe. The type of microbial agents can be one or more of the COD efficient degrading bacteria (mainly Bacillus subtilis, yeast, actinomycetes, etc.), nitrifying bacteria, aerobic nitrifying bacteria, and sulfiding bacteria currently on the market. It can be understood that the type of microbial agents does not affect the technical effect of the present invention.

[0038] In detail, the feeding pipe group 610 is provided with a U-shaped liquid seal structure 611 at one end close to the inner wall of the shell 100. The liquid seal structure 611 is used to prevent the overflow of methane or other harmful gases. At the same time, in order to prevent the microbial agent from dissolving in the liquid retained in the liquid seal structure 611, the operator can use the feeding air pump to guide the microbial agent into the interior of the shell 100 and evenly spray it into the slag and liquid. The feeding pipe group 610 can also be provided with a liquid tank, which is connected to the liquid seal structure 611. After the feeding air pump guides the microbial agent into the interior of the shell 100, the liquid in the liquid seal structure 611 will inevitably decrease. At this time, the liquid in the liquid seal structure 611 can be replenished through the liquid tank.

[0039] In one embodiment, the organic waste separation device 1000 also includes a liquid outlet component 700, which also includes a liquid pump 710 and a one-way pipe group 720. The one-way pipe group 720 is arranged through the shell 100 and at least one end of the one-way pipe group 720 is connected to the liquid pump 710. The liquid pump 710 is fixedly arranged on the outer wall of the shell 100.

[0040] The liquid fertilizer obtained after the liquid is converted by the reaction bed assembly 500 is discharged outward through a one-way pipe assembly 720 connected to the liquid pump 710. The one-way pipe assembly 720 is correspondingly provided with a valve on the shell 100. The operator turns the valve to discharge the liquid fertilizer from the shell 100 to the outside, which facilitates the collection and transfer of the liquid fertilizer.

[0041] In one embodiment, the push rod assembly 300 includes fan blades 310 and a push rod 320. The push rod 320 is arranged inside the rolling screen assembly 200 along the axial direction of the rolling screen assembly 200, and the push rod 320 is arranged to rotate along the axial direction of the rolling screen assembly 200. There are multiple fan blades 310, and the multiple fan blades 310 are fixedly arranged at an angle along the circumference of the push rod 320.

[0042] Specifically, in this embodiment, the push rod assembly 300 is a spiral push rod 320 , which rotates to drive the fan blades 310 to rotate along the axis of the push rod 320 , thereby driving the viscous material residue in the screen frame of the rolling screen assembly 200 to be discharged outward.

[0043] It is understandable that in other embodiments, the push rod 320 can be a push plate. After the rolling screen assembly 200 completes the initial filtration and obtains the viscous residue, the push plate is used to push the residue out of the screen frame and make the residue fall onto the vibrating screen assembly 400.

[0044] In one embodiment, the organic waste separation device 1000 also includes a drying component 800, which is arranged inside the shell 100 along the circumference of the vibrating screen component 400. The drying component 800 also includes a heater 810 and a rolling roller 820. The rolling roller 820 is mounted above the vibrating screen component 400, and the rolling roller 820 is rotatably connected along the axial direction of the vibrating screen component 400. The heater 810 is arranged on the circumference of the vibrating screen component 400.

[0045] In one embodiment, the heater 810 can be a hot air blower, and in another embodiment, the drying component 800 can be an electromagnetic heating wire. It can be understood that the specific heating method of the heater 810 does not affect the technical effect of the present invention, and the corresponding heating method can be selected according to actual needs. At the same time, the heater 810 has a temperature control device to avoid dangerous accidents such as flash or fire of flammable and explosive gases generated during the separation process of organic waste.

[0046] In one embodiment, the organic waste separation device 1000 also includes a slag collecting device 900, at least one end of which is disposed inside the shell 100 and below the vertical projection of the corresponding vibrating screen assembly 400, and at least one end of the slag collecting device 900 is disposed through the shell 100.

[0047] In this embodiment, the slag collecting device 900 is sucked out from the inside of the shell 100 through an air pump. A one-way valve is provided on the side of the slag collecting device 900 away from the shell 100. After the operator starts the air pump, the one-way valve is opened, and the air pump generates negative pressure on the bottom of the shell 100 to suck out the solid fertilizer.

[0048] In another embodiment, the slag collecting device 900 includes a scraper and a scraper motor. The scraper motor and the scraper are electrically connected, and the scraper is in contact with the reaction bed assembly 500. When the slag needs to be discharged from the organic waste separation device 1000, the operator starts the scraper motor, and the scraper motor drives the scraper to discharge the solid fertilizer remaining at the bottom of the shell 100. It can be understood that the specific form and driving method of the scraper will not affect the technical effect of the present invention.

[0049] In another embodiment, the slag collecting device 900 further includes a quality sensor and an alarm device. The quality sensor is used to detect the quality of the solid fertilizer stored in the shell 100. When the solid fertilizer stored in the shell 100 reaches a threshold, the alarm device sounds an alarm and notifies the operator to discharge the solid fertilizer in time.

[0050] The utility model is provided with a multi-screen group organic waste separation device with a rolling screen assembly and a vibrating screen assembly. In the process of separating organic waste in the field of poultry and livestock manure treatment technology, the operator passes sewage mixed with poultry and livestock manure into the shell, and after initial screening by the rolling screen assembly, viscous material residue (poultry and livestock manure) and material liquid are obtained, and then the push rod assembly pushes the viscous material residue to the vibrating screen assembly for further separation to obtain dry material residue. The material residue and the material liquid are converted into liquid agricultural fertilizer by a reaction bed assembly with a microbial agent, and the obtained dry material residue is converted into solid agricultural fertilizer, thereby avoiding waste of available resources and serious environmental pollution, achieving efficient separation in the separation process, and further realizing full utilization of available resources.
