Detailed Description
The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present invention, based on the embodiments of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution:
examples:
as shown in fig. 1 to 3, a rural solid waste treatment device comprises a cleaning tank 1 and a soil-film separation mechanism 2, wherein the soil-film separation mechanism 2 is arranged in the cleaning tank 1;
the soil film separating mechanism 2 is horizontally arranged, the soil film separating mechanism 2 comprises a separating cylinder 3, a soil crushing roller 4 and a connecting piece 5, the separating cylinder 3 is rotationally connected with the cleaning tank 1 through the connecting piece 5, the soil crushing roller 4 is rotationally connected inside the separating cylinder 3 through the connecting piece 5, the axis of the soil crushing roller 4 and the axis of the separating cylinder 3 are arranged in parallel at intervals, a plurality of soil outlet holes 6 are formed in the cylinder wall of the separating cylinder 3, and a feeding cover 7 is detachably connected to the separating cylinder 3;
the soil-film separating mechanism 2 is driven to rotate by a driving device 8;
the bottom of the cleaning tank 1 is provided with a soil outlet 9.
The connecting piece 5 comprises a first rotating shaft 10, a second rotating shaft 11 and a driving wheel 12, one end of the first rotating shaft 10 is in transmission connection with the driving device 8, the other end of the first rotating shaft 10 is connected with the driving wheel 12, one end of the second rotating shaft 11 is fixedly connected with the driving wheel 12, the second rotating shaft 11 is eccentrically connected with the driving wheel 12, and the other end of the second rotating shaft 11 is fixedly connected with the soil breaking roller 4;
the driving wheel 12 is disposed in the separating cylinder 3, the separating cylinder 3 is fixedly connected with the first rotating shaft 10, and the axis of the first rotating shaft 10 is coaxial with the axis of the separating cylinder 3.
The driving device 8 is a stepping motor.
The feeding cover 7 is connected with the separating cylinder 3 in a plug-in connection.
Working principle: the feeding cover 7 is opened, and the agricultural film with soil is put into the separating cylinder 3, wherein the putting amount of the agricultural film is 60-85% of the capacities of the separating cylinder 3 and the soil crushing roller 4. After the feeding cover 7 is closed, the driving device 8 is started, the driving device 8 drives the first rotating shaft 10 to rotate, and the first rotating shaft 10 drives the separating cylinder 3 and the driving wheel 12 to rotate. The driving wheel 12 drives the second rotating shaft 11 to synchronously rotate, and the second rotating shaft 11 rotates to drive the soil crushing roller 4 to rotate. When the soil breaking roller 4 rotates, the second rotating shaft 11 is deviated from the axle center of the driving wheel 12, so that the soil breaking roller 4 can rotate relative to the separating drum 3. When the soil crushing roller 4 rotates, the agricultural film with soil is pressed, and the projections on the agricultural film are crushed. The crushed soil particles are separated from the agricultural film and are in a free state in the separating cylinder 3.
When the separating cylinder 3 rotates, the crushed soil particles fly out of the soil outlet 6 and enter the cleaning tank 1 under the action of centrifugal force. The crushed soil particles are accumulated at the bottom of the cleaning tank 1. In the rotation process of the soil breaking roller 4, because the axis of the soil breaking roller 4 is spaced from the axis of the separating cylinder 3, when the soil breaking roller 4 moves, as shown in the figure, the distance x1 between the lower side of the soil breaking roller 4 and the separating cylinder 3 is smaller than the distance x2 between the upper side of the soil breaking roller 4 and the separating cylinder 3 (the diameter of the x1+x2+the soil breaking roller 4 is equal to the inner diameter of the separating cylinder 3), and the lower side of the soil breaking roller 4 also has the function of fixing a film when the soil-carrying film is extruded. The movement of the broken soil particles in the space with the larger side is intense, and the shielding of the agricultural film to the soil outlet 6 can be reduced due to the limitation of the displacement of the agricultural film, so that the broken soil particles can smoothly fly out of the soil outlet 6. When the soil breaking roller 4 continues to displace, the agricultural film rolled by the soil breaking roller 4 is loosened, and the soil breaking particles are separated from the agricultural film under the action of centrifugal force.
Wherein, the movement of the soil breaking roller 4 relative to the separating cylinder 3 is as follows: the soil-crushing roller 4 rolls around the second rotation shaft 11 in the separating drum 3, so that the agricultural film with soil can be crushed comprehensively.
After the soil is separated from the film, a soil outlet 9 at the bottom of the cleaning tank 1 is opened, and the dried crushed soil particles are collected.
After the collection is completed, the soil outlet 9 is closed, water is injected into the cleaning tank 1, and the water amount is 1/2 of that of the separation barrel 3. In the process, the separating cylinder 3 rotates, so that all agricultural films in the separating cylinder 3 can be cleaned. The soil crushing roller 4 still continuously rolls the film in the separating cylinder 3, (the residual soil on the agricultural film becomes slurry after meeting water) so as to extrude the slurry out of the film, thereby realizing the final separation of the soil and the agricultural film and replacing manual cleaning. After the cleaning is finished, the soil outlet 9 is opened, the mixed solution of slurry and water is discharged from the soil outlet 9, the mixed solution is collected to a sedimentation tank, supernatant after sedimentation can be used for cleaning an agricultural film, and bottom sedimentation can return to a farmland after drying, so that soil loss is reduced.
In the water discharging process, the soil-film separation mechanism 2 continues to rotate. The rotation process of the separating cylinder 3 provides centrifugal force for the film in the separating cylinder 3, and the water in the agricultural film enters the cleaning tank 1 through the soil outlet 6 under the action of the centrifugal force. When the soil breaking roller 4 rotates, water in the agricultural film is extruded, so that the water in the agricultural film is separated in an accelerating way. The agricultural film is dehydrated through the rotation of the soil film separating mechanism 2, and the drying of the agricultural film after cleaning can be accelerated.
Wherein, in order to avoid the overflow of dust generated in the soil film separation process, a detachable sealing cover can be additionally arranged at the top of the cleaning tank 1.
The rural solid waste treatment device replaces the traditional manual agricultural film cleaning and soil-film separation in a mechanized mode, and the soil-film separation and cleaning are carried out in steps, so that the slurry amount during film cleaning can be reduced, and the soil loss caused by cleaning is avoided; the soil-film separation mechanism 2 has three functions, can be used for soil-film separation, film cleaning and dehydration after film cleaning, and has strong practicability.
Further, as shown in fig. 1 and 2, the feeding cover 7 is provided with a soil outlet 6. The arrangement can ensure that the crushed soil particles and water can be separated from the separating cylinder 3 from the feeding cover 7, so that the separating effect is improved.
Further, as shown in fig. 1, the bottom of the cleaning tank 1 has an inverted cone structure. The accumulation of convenient broken soil granule is so set up, can reduce simultaneously when putting soil, the deposit of broken soil granule in the cleaning tank 1 bottom.
Further, as shown in fig. 3, a water inlet hole is formed in the top of the cleaning tank 1, the water inlet hole is connected with a water source through a water pipe 13, and the bottom of the cleaning tank 1 is connected with a three-way valve 14 through a joint.
During cleaning, clean water is injected into the cleaning tank 1 through the water inlet holes for cleaning. After the soil film is separated, the three-way valve 14 is opened to a vertical communication state, so that the crushed soil particles can be discharged rapidly under the action of gravity. After the cleaning is finished, the three-way valve 14 is opened to an L-shaped communication state that the soil outlet 9 is communicated with the water outlet on the right side, so that water is conveniently discharged. This arrangement allows for separate collection of the crushed soil particles and the slurry.
Further, the soil breaking roller 4 is made of PETG material. PETG is the material of light in weight, hardness is big, intensity is enough, so sets up can alleviate the heavy burden of second pivot 11, guarantees second pivot 11 life.
Further, the soil breaking roller 4 is a cylindrical shell structure with two closed ends and hollow. Hollow soil breaking rolls may further reduce the weight of the soil breaking rolls.
The foregoing is merely a preferred embodiment of the invention, and it is to be understood that the invention is not limited to the form disclosed herein but is not to be construed as excluding other embodiments, but is capable of numerous other combinations, modifications and environments and is capable of modifications within the scope of the inventive concept, either as taught or as a matter of routine skill or knowledge in the relevant art. And that modifications and variations which do not depart from the spirit and scope of the invention are intended to be within the scope of the appended claims.
