Description

Technical Field

[0001] The utility model belongs to the technical field of extrusion dehydration, and specifically provides a duckbill type dehydration extruder. Background Art

[0002] With the continuous development of garbage disposal technology, related technical solutions use extrusion dehydration to compress organic materials or garbage into denser blocks. During the compression process of the materials or garbage, their own extrusion dehydration will be achieved simultaneously to reduce the water content of the compressed materials as much as possible.

[0003] In the related technical solution, a spiral extrusion device is used to dehydrate the material. The discharge end of the spiral extrusion device is provided with a conical stopper, which can slide and be fixed along the axial direction of the spiral extrusion device, thereby realizing the blocking and opening of the discharge end of the spiral extrusion device. When the conical stopper is blocked at the discharge end of the spiral extrusion device, the material moves in the direction close to the discharge end and is continuously compressed and dehydrated; when the conical stopper is separated from the discharge end of the spiral extrusion device, the compressed material is separated from the discharge end.

[0004] However, in the above technical solution, the direction of movement of the shielding member is the same as the axial direction of the screw extruder. In order not to hinder the compressed material block discharged from the discharge end, the shielding member needs to be axially far away from the discharge end. In addition, the electric push rod or hydraulic push rod that drives the conical stopper also needs to occupy a longer size. That is, the cooperation between the conical stopper and the electric push rod in the above technical solution will cause the length of the entire duckbill dehydration extruder to be larger, which is not convenient for realizing the miniaturization design of the extrusion dehydration equipment. Utility Model Content

[0005] The utility model aims to provide a duckbill dehydration extruder, which can at least solve one of the above technical problems.

[0006] In order to solve the above-mentioned problems in the prior art, one or more embodiments of the utility model provide a duckbill dehydration extruder, including a frame, on which a horizontally placed screw conveying mechanism is installed, the two ends of the screw conveying mechanism respectively form a feeding end and a discharging end, the outer wall of the screw conveying mechanism is provided with a water filter hole, and the frame is provided with a discharging barrel connected to the inner cavity of the screw conveying mechanism near the discharging end, and two pressing plates are rotatably installed in the discharging barrel, one end of the pressing plate is rotatably connected to the discharging barrel and the rotation axis is vertically arranged, and the other end of the pressing plate forms a free end, and the upper and lower end surfaces of the pressing plate can respectively fit with the inner wall surface of the inner cavity of the discharging barrel; the two pressing plates can be rotated until the two free ends abut to block the discharging barrel, or the two pressing plates can be rotated under the drive of the hydraulic push rod until the two free ends are away from each other to open the discharging barrel.

[0007] Beneficial effects of one or more of the above technical solutions:

[0008] Compared with the method of directly filling a conical stop block at the end of the discharge end of the screw conveying mechanism in the prior art: in this solution, a discharge barrel is set at the end of the screw conveying mechanism, and two pressure plates are rotatably installed in the discharge barrel. The upper end surface and the lower end surface of the pressure plate can respectively fit with the inner wall surface of the discharge barrel; the two pressure plates can rotate with each other to open or close the discharge barrel. That is, the two pressure plates in this solution can form an openable and closable structure similar to a duckbill through the rotation of the two pressure plates. This arrangement method is convenient for reducing the space occupied by the pressure plate and the driving mechanism that drives the pressure plate to rotate in the axial length direction of the extrusion dehydration equipment, can avoid the situation where the pressure plate hinders the discharge of the material compression block, and is convenient for realizing the miniaturized design of the entire extrusion dehydration equipment.

[0018] like Figure 1-Figure 4 As shown, a duckbill dehydration extruder provided in this embodiment includes a frame 1, on which a horizontally placed screw conveying mechanism is installed, and the two ends of the screw conveying mechanism respectively form a feeding end and a discharging end, and the outer wall of the screw conveying mechanism is provided with a water filter hole, and the frame 1 is provided with a discharging barrel 5 connected to the inner cavity of the screw conveying mechanism near the discharging end, and two pressing plates 7 are rotatably installed in the discharging barrel 5, one end of the pressing plate 7 is rotatably connected to the discharging barrel 5 and the rotation axis is vertically arranged, and the other end of the pressing plate 7 forms a free end, and the upper and lower end surfaces of the pressing plate 7 can respectively fit with the inner wall surface of the inner cavity of the discharging barrel 5; the two pressing plates 7 can be driven by a hydraulic push rod 71 to rotate until the two free ends abut to block the discharging barrel 5, or the two pressing plates 7 can rotate until the two free ends are away from each other to open the discharging barrel 5.

[0019] Specifically, the horizontal arrangement of the screw conveying mechanism here means that the rotating shaft of the screw conveying mechanism and the screw conveying space are both arranged horizontally. The feeding end of the screw conveying mechanism inputs materials, and the discharging end outputs materials; the outer wall of the screw conveying mechanism is evenly provided with water filter holes, which are preferably circular holes. In some other embodiments, the water filter holes can also be square holes or elliptical holes.

[0020] Specifically, the inner cavity of the discharge barrel forms a discharge port 6, and the discharge port 6 connects the discharge end of the spiral conveying mechanism with the external space. When the free ends of the two pressing plates 7 abut against each other, the two pressing plates enclose a compression space 72 between the discharge port and the discharge end of the spiral conveying mechanism. At this time, the compression space 72 is a space separated from the external environment by the inside of the discharge port 6. More specifically, the compression space 72 is a triangular space.

[0021] In this embodiment, the pressure plate is a square plate, which is arranged roughly vertically and perpendicular to the top and bottom walls of the discharge barrel. Therefore, the upper end of the square plate can fit the top wall of the inner cavity of the discharge barrel, and the lower end of the square plate can fit the bottom wall of the inner cavity of the discharge barrel.

[0022] In this embodiment, the discharge barrel 5 includes a top plate, a bottom plate 51 and two side plates, each of which is rotatably connected to a pressure plate 7. The bottom plate 51 is rotatably connected to the frame 1 at one end close to the screw conveying mechanism, and the rotation axis of the bottom plate 51 is horizontal and perpendicular to the axial direction of the screw conveying mechanism.

[0023] Specifically, when the top plate, the bottom plate and the two side plates are used to enclose the discharge barrel, the cross section of the discharge barrel perpendicular to its own conveying direction is a fixed cross section and the cross section is approximately square. The hydraulic housing of the hydraulic push rod 71 is rotatably connected to the inner wall surface of the side plate, and the driving end of the driving rod of the hydraulic push rod is rotatably connected to the outer wall of the pressing plate 7.

[0024] See also Figure 3 or Figure 4 The frame 1 includes a vertically arranged partition 12, the center of which has a circular hole, and the partition is used to separate the screw conveying mechanism and the discharge barrel along the axial direction of the extrusion dehydration device. More specifically, the side plate and the top plate of the discharge barrel are fixed to the side of the partition away from the screw conveying mechanism. In this embodiment, the partition and the outer shell of the screw conveying mechanism are a common plate member at the part close to the discharge barrel.

[0025] In this embodiment, a driving mechanism is installed between the frame 1 and the bottom plate 51, and the driving mechanism is used to drive the bottom plate 51 to rotate between a horizontal state and a tilted downward state.

[0026] It can be known that after the screw conveyor mechanism outputs the compressed material block from its own discharge end, the material is transported outward from the discharge barrel 5, and the material that is easily left at the discharge barrel is on the bottom plate 51 of the discharge barrel. At this time, the bottom plate 51 is rotated to make the end of the bottom plate 51 away from the screw conveyor mechanism tilted and removed to discharge the participating materials.

[0027] In this embodiment, the driving mechanism includes an electric push rod 52, the housing of the electric push rod 52 is rotatably connected to the frame 1, and the driving rod of the electric push rod is rotatably connected to the bottom wall of the bottom plate 51. In some other embodiments, the electric push rod can be replaced by a hydraulic push rod.

[0028] In this embodiment, the inner cavity of the screw conveyor mechanism is higher than the bottom plate 51 at the discharge end. When the discharge end is higher than the bottom plate 51 as a whole, there is a height difference between the bottom end of the inner cavity of the screw conveyor mechanism and the upper surface of the bottom plate, and the existence of this height difference can prevent the screw conveyor mechanism from accumulating materials that cannot be discharged at the discharge end.

[0029] In this embodiment, the spiral conveying mechanism includes a spiral blade shaft and a cylinder 8 sleeved on the outside of the spiral blade shaft, the cylinder 8 has a water filter hole, one end of the cylinder 8 forms a feed end, and the other end forms a discharge end. The feed end is connected to the hopper 31, and the hopper 31 has a feed port 3 set up upper and lower.

[0030] In this embodiment, one end of the spiral blade shaft extends out of the feed end of the barrel 8 and is connected to the power source, and the other end extends to be flush with the discharge end of the barrel 8. In this embodiment, the power source is a hydraulic motor 2. The conveying shaft of the hydraulic motor 2 is coaxially fixed with the spiral blade shaft through a coupling, and the housing of the hydraulic motor 2 is supported and fixed by the frame 1.

[0031] In this embodiment, a housing 4 is further included, which covers the outside of the screw conveying mechanism, and a gap 11 is formed between the housing 4 and the outer wall of the screw conveying mechanism. The lower part of the housing 4 has a drain port 91 connected to the gap 11. The gap 11 is arranged roughly around the cylinder 8, and the gap 11 can accommodate water flowing out of the coin filtering hole of the cylinder, and is concentrated at the bottom of the gap under the action of gravity.

[0032] Specifically, the upper end of the hopper 31 passes through the upper part of the outer shell of the screw conveying mechanism, and the lower end of the hopper 31 passes downward through the upper wall of the cylinder to communicate with the inner cavity of the cylinder.

[0033] In this embodiment, the lower part of the housing 4 forms a water collecting tank 9 which is wide at the top and narrow at the bottom, and the bottom of the water collecting tank 9 has the drain port 91. More specifically, the drain port 91 is provided with a valve which can be opened and closed.

[0034] So far, the technical solution of the present application has been described in conjunction with the preferred embodiments of the foregoing text, but it is easy for those skilled in the art to understand that the protection scope of the present application is not limited to the above preferred embodiments. Without departing from the technical principles of the present application, those skilled in the art may split and combine the technical solutions in the above preferred embodiments, and may also make equivalent changes or replacements to the relevant technical features, and any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principles of the present application will fall within the protection scope of the present application.
