Description

Technical Field

[0001] The invention belongs to the technical field of organic solid waste treatment, and in particular relates to an organic solid waste treatment device. Background Art

[0002] There are many types of organic solid waste that need to be separated into dry and wet types, such as kitchen waste (leftovers, fruit peels, cores, bones, eggshells, etc.), livestock and poultry manure (including pig manure, cow manure, chicken manure, etc.), garden waste (branches, leaves, grass clippings, etc.), etc.

[0003] At present, in the field of organic solid waste dry-wet separation technology, inclined screen dry-wet separators, auger dry-wet separators or a combination of the two are often used to achieve the purpose of separation. The inclined screen dry-wet separator includes a machine body, a sieve plate is fixedly connected to the machine body through a spring, a screen is fixedly connected between the sieve plates, the sieve plate and the screen are both inclined, a vibration motor is connected to the sieve plate, and the vibration motor drives the screen and the sieve plate to vibrate; a feed hopper is also provided on the top of the machine body, and the discharge end of the feed hopper is located directly above the top of the screen, and a liquid collection tank is provided in the machine body, and the liquid collection tank is located directly below the screen. Taking the dry-wet separation of feces as an example, after the feces enters from the feed hopper, under the action of the vibration motor, the liquid part passes through the screen and flows into the liquid collection tank below, and the solid part slides along the surface of the screen, and finally falls from the discharge end of the screen into the solid collection device.

[0004] The above-mentioned inclined screen type dry-wet separator has a simple structure and can quickly achieve dry-wet separation of organic solid wastes such as feces. However, for organic solid wastes with high viscosity such as livestock and poultry manure, the solid part can easily block the mesh holes of the screen, and the liquid can only be separated from the solid part by vibration and gravity, resulting in unsatisfactory separation effect and more water easily remaining in the solid part. Summary of the invention

[0005] The present invention aims to provide an organic solid waste treatment device to improve the dehydration rate of organic solid waste with high viscosity such as livestock and poultry manure.

[0006] An organic solid waste treatment device in the present scheme comprises an inclined screen type dry-wet separator, which comprises a machine body, a sieve plate is fixedly connected to the machine body through a spring, a sieve mesh is fixedly connected between the sieve plates, the sieve plate and the sieve mesh are both inclined, and a vibration motor is connected to the sieve plate; a liquid collecting tank is arranged in the machine body, and the liquid collecting tank is located directly below the sieve mesh; a diamond-shaped telescopic frame is arranged on the machine body, the telescopic direction of the diamond-shaped telescopic frame is consistent with the length direction of the sieve mesh, the bottom of the diamond-shaped telescopic frame is in contact with the sieve mesh, an electric-controlled telescopic rod for pushing the diamond-shaped telescopic frame to be telescopic is fixedly connected to the machine body, and when the diamond-shaped telescopic frame is retracted to the maximum extent, both sides of the diamond-shaped telescopic frame are in contact with the sieve plate or leave a gap of 0.1 to 10 mm.

[0007] The working principle and beneficial effects of this scheme: Taking the treatment of feces with high adhesion as an example, the feces enters the top of the screen of the inclined screen type wet-dry separator. The vibration motor drives the screen plate and the screen to vibrate, so that part of the liquid flows into the liquid collection tank through the screen under the action of gravity and vibration. At the same time, the electric telescopic rod can push the diamond telescopic frame to perform telescopic movement. When the electric telescopic rod is extended, the diamond telescopic frame extends along the length direction of the screen. During this process, the distance between the two sides of the diamond telescopic frame is reduced, and the gap between the diamond telescopic frame and the screen plates on both sides is increased. The feces moves to the sides of the diamond telescopic frame and enters the gap on both sides of the diamond telescopic frame. After the diamond telescopic frame extends to the top, the electric telescopic rod controls it to retract, so that the gap between the sides of the diamond telescopic frame is reduced, and the feces are squeezed. After the feces are squeezed, a large amount of liquid in the feces is discharged and falls from the screen into the liquid collection tank below. After that, the feces that have undergone preliminary dry-wet separation are discharged from the discharge end of the screen. This solution achieves multiple extrusion dehydration of organic solid waste while ensuring continuous dry-wet separation of organic solid waste through the setting of diamond-shaped telescopic frames, greatly improving the dehydration rate of organic solid waste, especially organic solid waste with high viscosity such as livestock and poultry manure.

[0008] Furthermore, the diamond-shaped telescopic frame includes a diamond frame and two groups of support parts, the diamond frame is composed of multiple upper support rods, lower support rods and hinged rods, both ends and middle parts of the upper support rods and the lower support rods are connected with hinged rods, and multiple upper support rods and the lower support rods are hingedly connected to form a diamond frame through the hinged rods, and the support parts include a connecting rod and two support rods, one end of the two support rods is hinged together through the connecting rod, and the free ends of the two support rods of the two groups of support parts are respectively hinged to the upper support rods and the lower support rods at both ends of the diamond frame; one of the connecting rods is fixedly connected to a horizontal plate perpendicular to it, and both ends of the horizontal plate are fixedly connected to the machine body; the telescopic rod of the electric control telescopic rod is fixedly connected to an adjusting rod, and the other end of the adjusting rod is provided with a through hole perpendicular to its length direction, and one of the hinged rods in the middle of the diamond frame is rotatably connected in the through hole. Taking the separation of dry and wet feces as an example, when the lifting and retracting rod of the electric telescopic rod is extended, it drives the adjusting rod to move toward the feed end of the screen, thereby driving the diamond-shaped telescopic frame to extend. During this process, the two ends of the upper support rod and the lower support rod move closer to the middle hinged rod, so that the angle between the hinged upper support rod and the lower support rod increases, and a large amount of feces enters the angle; and when the electric telescopic rod drives the diamond-shaped telescopic frame to retract, the angle between the hinged upper support rod and the lower support rod decreases, thereby squeezing the feces, thereby squeezing the liquid in the feces.

[0009] Furthermore, the through hole of the adjusting rod is connected to the hinge rod at the bottom and in the middle of the rhombus frame, which helps to reduce the length of the adjusting rod.

[0010] Further, the screen is made of stainless steel, and the lower surfaces of the upper support rod, the lower support rod and the support rod are provided with steel brushes or nylon brushes. The provision of steel brushes or nylon brushes helps to improve the cleaning of the screen mesh and avoid clogging.

[0011] Furthermore, a baffle for shielding the diamond-shaped telescopic frame is detachably connected to the sieve plate, and the baffle is located between the vibration motor and the diamond-shaped telescopic frame. The setting of the baffle helps to prevent organic solid waste from flying out.

[0012] Furthermore, a feed hopper is provided on the top of the machine body, and a discharge end of the feed hopper is located directly above the screen, so that the organic solid waste can be evenly placed on the screen.

[0013] Furthermore, a storage tank is provided in the machine body, and the storage tank is located directly below the discharging end of the screen, so as to collect the solid part after the preliminary separation by the inclined screen type dry-wet separator, so as to facilitate the subsequent processing or transportation.

[0014] Furthermore, the sieve plate is detachably connected with a fixing plate, the vibration motor is mounted on the fixing plate, and the fixing plate is located above the diamond-shaped telescopic frame, so as to facilitate the installation, disassembly and maintenance of the vibration motor.

[0015] Furthermore, an auger-type dry-wet separator is connected to the storage tank, and the feed end of the auger-type dry-wet separator is located directly below the discharge end of the screen. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The machine body 2 is provided with a rhombus-shaped telescopic frame 14, the telescopic direction of the rhombus-shaped telescopic frame 14 is consistent with the length direction of the screen 9, and the bottom of the rhombus-shaped telescopic frame 14 is in contact with the screen 9. More specifically: the rhombus-shaped telescopic frame 14 is as shown in the attached Figure 4As shown, it includes a diamond frame and two groups of support parts. The diamond frame is composed of five upper support rods 141, five lower support rods 142 and seventeen hinged rods 143. The upper support rods 141 and the lower support rods 142 are connected to the hinged rods 143 at both ends and the middle part. The upper support rods 141 and the lower support rods 142 are hinged to form a diamond frame through the hinged rods 143. The support parts include a connecting rod 144 and two support rods 145. One end of the two support rods 145 is hinged together through the connecting rod 144. The free ends of the two support rods 145 of the two groups of support parts are respectively hinged to the upper support rods 141 and the lower support rods 142 at both ends of the diamond frame. The lower surfaces of the upper support rods 141, the lower support rods 142 and the support rods 145 are provided with steel brushes; a connecting rod 144 away from the feed hopper 1 is fixedly connected with a vertical A horizontal plate 10, both ends of which are fixedly connected to the machine body 2; a mounting plate 6 is detachably connected to the machine body 2, an electrically controlled telescopic rod is mounted on the mounting plate 6, a hydraulic cylinder 7 is selected for the electrically controlled telescopic rod, and an "L"-shaped fixed rod 5 is fixedly connected to the telescopic rod of the electrically controlled telescopic rod, and an adjusting rod 13 is fixedly connected to the other end of the fixed rod 5; the other end of the adjusting rod 13 is provided with a through hole perpendicular to its length direction, and a hinged rod 143 at the bottom and in the middle of the rhombus frame is rotatably connected to the through hole of the adjusting rod 13; when the rhombus telescopic frame 14 is retracted to the maximum, a gap of 0.1 to 0.5 mm is left between the two sides of the rhombus telescopic frame 14 and the sieve plate 12; a baffle 11 for shielding the rhombus telescopic frame 14 is detachably connected to the sieve plate 12, and the baffle 11 is located between the vibration motor 4 and the rhombus telescopic frame 14.

[0025] Xinjie Electric PLC controller XD3 is selected to control the on and off of the hydraulic cylinder 7 and the vibration motor 4, and to control the extension and retraction of the hydraulic cylinder 7 and the operation of the vibration motor 4.

[0026] The specific implementation process is as follows: Taking livestock and poultry manure treatment as an example, first, the livestock and poultry manure enters the inclined screen type wet-dry separator from the feed hopper 1 and falls on the top of the screen 9. At this time, the PLC controller controls the vibration motor 4 to start, driving the screen plate 12 and the screen 9 to vibrate. Under the dual effects of gravity and vibration, part of the liquid passes through the screen 9 and flows into the liquid collection tank.

[0027] At the same time, the PLC controller controls the electric telescopic rod to start working, and the telescopic rod stretches, driving the adjustment rod 13 to move toward the feeding end of the screen 9. Due to the connection between the diamond frame and the adjustment rod 13, the diamond telescopic frame 14 begins to stretch along the length direction of the screen 9, and the ends of the upper support rod 141 and the lower support rod 142 move closer to the middle hinge rod 143, so that the angle between the hinged upper support rod 141 and the lower support rod 142 increases. In this process, the feces moves to the two sides of the diamond telescopic frame 14 and enters the gradually increasing gap between the two sides of the diamond telescopic frame 14 and the screen plate 12.

[0028] When the diamond-shaped telescopic frame 14 is extended to the top, the telescopic rod of the electric telescopic rod retracts, driving the diamond-shaped telescopic frame 14 to retract. At this time, the angle between the upper support rod 141 and the lower support rod 142 is reduced, squeezing the feces entering the gaps on both sides thereof, squeezing a large amount of liquid in the feces, and the liquid passes through the screen 9 and falls into the liquid collecting tank.

[0029] During the whole process, the steel brush moves on the upper surface of the screen 9 with the movement of the diamond-shaped telescopic frame 14, cleaning the mesh of the screen 9 to prevent feces from clogging the mesh. The baffle 11 plays a blocking role to prevent feces from flying out of the body 2 during the vibration and movement of the diamond-shaped telescopic frame 14.

[0030] Embodiment 2 is basically as attached Figure 5 As shown, the only difference from Example 1 is that an auger-type dry-wet separator 15 is connected to the storage tank 8 , and the feed end of the auger-type dry-wet separator 15 is located directly below the discharge end of the screen 9 .
