Description

Technical Field

[0001] This utility model relates to the field of biomass waste treatment and sanitation equipment technology, and in particular to a biomass waste pressing equipment. Background Technology

[0002] Biomass waste includes kitchen waste, food waste, feces, and waste cooking oil. Compared with household waste, biomass waste is characterized by high viscosity, fine particle size, easy decomposition, and high moisture content. In existing technologies, waste compactors primarily operate by using hydraulic cylinders to push and compress waste. This type of compaction equipment mainly consists of the compressor body, hydraulic cylinders, and a pusher structure. During operation, waste enters the feed inlet, and the extension and retraction of the hydraulic cylinders drives the pusher to push and compress the waste into the transfer container.

[0003] Existing waste compaction equipment, when processing biomass waste, has gaps between the reciprocating pusher head and the left and right sides and bottom of the compressor body. Wastewater flows to the rear of the pusher head, and when the pusher head retracts, it scrapes the fine debris in the gaps to the rear, thus greatly increasing the labor intensity of manual cleaning. At the same time, existing waste compactors lack drainage structures and have poor water-draining performance, making them unsuitable for easily perishable and high-moisture biomass waste.

[0004] Therefore, there is an urgent need for a biomass waste pressing equipment to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a biomass waste pressing equipment for pressing biomass waste, thereby reducing the labor intensity of manual cleaning operations.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model provides a biomass waste compression equipment, which includes: an installation base, a compression box, a screw conveyor compression assembly, a drive assembly, and a transfer box. A mounting base is provided for installation; a pressing box is installed on the mounting base; the pressing box extends along a first direction; the first direction is horizontal; a filter hole is provided at the bottom of the pressing box; the pressing box includes an inlet box and a conveying box arranged and connected along the first direction; an inlet is provided at the top of the inlet box; an outlet is provided at the end of the conveying box; the opening direction of the outlet is parallel to the first direction; a screw conveying compression assembly is disposed in the pressing box along the first direction; in a second direction, the screw conveying compression assembly is at least partially located below the inlet; the second direction is at an angle to the first direction; a drive assembly is drivenly connected to the screw conveying compression assembly and is capable of driving the screw conveying compression assembly to screw convey the waste from the inlet to the outlet; a transfer box is capable of docking with the outlet to receive the waste discharged from the outlet.

[0008] In some embodiments, the helical conveying and compression assembly is a shafted helical conveying and compression assembly, including a rotating shaft and helical blades helically wound around the rotating shaft.

[0009] In some embodiments, the rotating shaft is a variable diameter shaft.

[0010] In some embodiments, the helical blades have a constant outer diameter structure.

[0011] In some embodiments, the spiral conveying and compression assembly consists of variable pitch spiral blades that extend spirally along the first direction.

[0012] In some embodiments, the variable pitch helical blades located within the feed box have a greater pitch at the feed end than at the discharge end.

[0013] In some embodiments, a feeding funnel is provided at the opening of the feed inlet; the opening size of the feeding end of the feeding funnel is larger than the opening size of the discharging end of the feeding funnel, and the discharging end of the feeding funnel is connected to the interior of the feed box.

[0014] In some embodiments, a liquid receiving tank is provided on the lower side of the pressing box; in the second direction, the opening of the liquid receiving tank is positioned directly opposite the water filter hole.

[0015] In some embodiments, the biomass waste pressing equipment further includes a push-pull assembly disposed on the lower side of the pressing box; the push-pull assembly can pull the transfer box so that the transfer box fits against the discharge port.

[0016] In some embodiments, the biomass waste pressing equipment further includes a locking hook assembly disposed on both sides of the pressing box; a locking groove is provided at one end of the transfer box near the pressing box; the locking hook assembly can be engaged with the locking groove to lock the transfer box and the pressing box together.

[0017] The beneficial effects of this utility model are:

[0018] This invention provides a biomass waste pressing device. A pressing box is installed on a mounting base, with a filter hole at the bottom. The pressing box is divided into an inlet box and a conveying box. An inlet is located at the top of the pressing box, and an outlet is located at the end of the conveying box. A screw conveying compression assembly is installed inside the pressing box along a first direction, and a drive assembly is connected to the screw conveying compression assembly. The screw conveying compression assembly is driven to convey the waste from the inlet of the pressing box to the outlet. A transfer box is also provided to connect with the outlet of the pressing box to receive the waste discharged from the outlet. This allows for convenient pressing and transfer of waste when necessary. Waste can be fed into the pressing box through the inlet, the drive assembly drives the screw conveying compression assembly, and the screw conveying assembly conveys the waste from the inlet to the outlet, from where it is discharged into the transfer box for subsequent transfer processing. In the aforementioned process of compressing and transferring waste, a screw conveyor compression assembly is used to continuously convey the waste, eliminating the need for repeated pushing. This avoids the waste being carried out of the compression box by the pushing assembly during repeated pushing, thus preventing environmental pollution. Furthermore, it eliminates the need for extensive manpower for cleaning, saving labor and improving the efficiency of waste compression and transfer. Simultaneously, during this process, wastewater contained in the waste can be discharged through the filter holes at the bottom of the compression box, preventing indiscriminate spread and discharge of wastewater. This eliminates the need for subsequent manual cleaning, further saving manpower and ensuring environmental hygiene. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0030] Combination Figure 1 , Figure 2 As shown, this embodiment provides a biomass waste compression equipment, which includes: a mounting base 1, a compression box 4, a screw conveyor compression assembly 3, a drive assembly 5, and a transfer box 10.

[0031] The aforementioned mounting base 1 can be, for example, a mounting frame assembled from multiple crossbeams and longitudinal beams, or a mounting structure formed by a mounting plate and multiple support members. This mounting base 1 is used to provide an installation location.

[0032] like Figure 2 As shown, the aforementioned press-fit box 4 is mounted on the mounting base 1. The press-fit box 4 is, for example, cylindrical in shape. The press-fit box 4 extends along a first direction X1, where X1 is horizontal. A filter hole 6 is provided at the bottom of the press-fit box 4. It is readily understood that there can be multiple filter holes 6, evenly spaced at the bottom of the press-fit box 4. Furthermore, it is easy to understand that in some embodiments, such as... Figure 2 As shown, a liquid receiving tank 7 is also provided on the lower side of the pressing box 4. In the second direction X2, the opening of the liquid receiving tank 7 is directly opposite the filter hole 6. In other words, the position of the orthographic projection of the filter hole 6 in the second direction X2 is within the outer contour of the orthographic projection of the liquid receiving tank 7 in the second direction X2. This ensures that the wastewater discharged from the filter hole 6 can be collected by the liquid receiving tank 7, preventing wastewater from spreading and being discharged indiscriminately, thereby ensuring environmental hygiene.

[0033] The aforementioned pressing box 4 includes a feeding box and a conveying box arranged and connected along the first direction X1. The feeding box has an inlet at its top, and the conveying box has an outlet at one end. Figure 1 Taking the shown perspective as an example, the pressing box 4 includes a feeding box and a conveying box arranged on the left and right sides, and a discharge port is provided on the right side wall of the conveying box. The opening direction of the discharge port is parallel to the first direction X1, so that the waste fed in by the feeding port of the pressing box 4 can be easily discharged from the discharge port.

[0034] like Figure 1 As shown, the aforementioned screw conveyor compression assembly 3 is disposed on the pressing box 4 along the first direction X1. In the second direction X2, the screw conveyor compression assembly 3 is at least partially located below the inlet opening at the top of the feeding box. Here, the second direction X2 forms an angle with the first direction X1 mentioned above, for example, 90°. In other words, viewed from the second direction X2, at least a portion of the screw conveyor compression assembly 3 is exposed above the inlet opening at the top of the feeding box, allowing waste fed through the inlet to fall onto the screw conveyor compression assembly 3 for conveying.

[0035] The upper drive assembly 5 is connected to the screw conveyor compression assembly 3 via a transmission connection. This drive assembly 5 is, for example, a rotary motor. The output shaft of the drive assembly 5 can be directly connected to the screw conveyor compression assembly 3, or it can be connected to the screw conveyor compression assembly 3 via other transmission components (such as couplings, reduction gear sets, or pulleys). For example, using… Figure 1 Taking the shown perspective as an example, the drive assembly 5 is located on the left side of the aforementioned pressing box 4, and the drive assembly 5 is directly connected to the screw conveyor compression assembly 3 of the pressing box 4. This drive assembly 5 can drive the aforementioned screw conveyor compression assembly 3 to screw convey the waste fed in from the inlet to the outlet.

[0036] like Figure 1 As shown, the aforementioned transfer box 10 has, for example, a cuboid structure. This transfer box 10 can connect with the discharge port of the aforementioned pressing box 4 to receive waste discharged from the discharge port of the pressing box 4. It is easy to understand that a feed port is also provided on the side wall of the transfer box 10, and the opening direction of this feed port is parallel to the opening direction of the discharge port of the pressing box 4, that is, parallel to the first direction X1. The feed port of the transfer box 10 can connect with the discharge port of the pressing box 4.

[0037] Therefore, the biomass waste pressing equipment provided in this embodiment is provided by setting a pressing box 4 on the mounting base 1, opening a water filter hole 6 at the bottom of the pressing box 4, dividing the pressing box 4 into a feeding box and a conveying box, setting a feeding port at the top of the pressing box 4, setting a discharge port at the end of the conveying box, setting a spiral conveying compression assembly 3 in the pressing box 4 along the first direction X1, and setting a drive assembly 5 to drive the spiral conveying compression assembly 3 to convey the waste from the feeding port of the pressing box 4 to the discharge port of the pressing box 4. In addition, a transfer box 10 that can dock with the discharge port of the pressing box 4 is also provided to receive the waste discharged from the discharge port of the pressing box 4. This allows for efficient waste handling during pressurization and transfer. Waste is fed into the pressurization box 4 through the inlet, and the screw conveyor compression assembly 3, driven by the drive assembly 5, is used to convey the waste from the inlet to the outlet. From there, it is discharged into the transfer box 10 for further processing. During this process, the screw conveyor compression assembly 3 continuously conveys the waste, eliminating the need for repeated pushing and preventing waste from being carried out of the pressurization box 4 and causing environmental pollution. This also reduces the need for extensive cleaning, saving manpower and improving the efficiency of waste pressurization and transfer. Furthermore, wastewater contained in the waste can be discharged through the filter holes 6 at the bottom of the pressurization box 4, preventing indiscriminate spillage and discharge, further saving manpower and ensuring environmental hygiene.

[0038] In some embodiments, the aforementioned screw conveying and compression assembly 3 is a shafted screw conveying and compression assembly 3. The screw conveying and compression assembly 3 includes a rotating shaft and helical blades wound around the rotating shaft. The rotating shaft is drively connected to the aforementioned drive assembly 5.

[0039] For example, the aforementioned rotating shaft is a variable diameter shaft. The aforementioned helical blades have a constant outer diameter structure. Specifically, the diameter of the rotating shaft located inside the aforementioned feed box is larger than the diameter of the rotating shaft located inside the aforementioned conveying box. In other words, with Figure 1 Taking the shown perspective as an example, the rotating shaft has a tapered structure, with the diameter of its left end being larger than that of its right end. This design enhances the bending strength of the shaft's feed end, resisting lateral loads caused by waste accumulation and reducing shaft deflection. Simultaneously, it concentrates axial tensile force at the high-strength feed end, avoiding the risk of breakage due to stress concentration at the discharge end. Furthermore, setting the feed end of the rotating shaft to a large diameter reduces the filling space at the feed end of the screw conveyor compression assembly 3, thereby increasing axial thrust and suppressing waste backflow. Conversely, setting the discharge end of the rotating shaft to a small diameter increases the effective conveying volume at the discharge end of the screw conveyor compression assembly 3, preventing blockages caused by waste accumulation. Of course, the rotating shaft can also be arranged in a stepped structure, as long as the diameter of the rotating shaft within the feed box is larger than the diameter of the rotating shaft within the conveying box.

[0040] Of course, the aforementioned rotating shaft can also be a shaft of equal diameter. The aforementioned spiral blades have a structure of equal outer diameter. In the second direction X2, the inner diameter of the feed box of the aforementioned pressing box 4 is smaller than the inner diameter of the conveying box of the pressing box 4. By setting it in this way, the filling space at the feed end of the spiral conveying compression assembly 3 can be relatively reduced, thereby increasing the axial thrust and suppressing waste backflow; at the same time, the effective conveying volume at the discharge end of the spiral conveying compression assembly 3 can be increased, avoiding blockage caused by waste accumulation.

[0041] In some embodiments, the aforementioned screw conveying and compression assembly 3 is a variable-pitch helical blade extending helically along a first direction X1. This variable-pitch helical blade is connected to the aforementioned drive assembly 5. For example, a short-shaft flange is welded to one end of the variable-pitch helical blade, which is then connected to the reducer of the drive assembly 5 via high-strength bolts; alternatively, one end of the variable-pitch helical blade is rolled into a tapered sleeve, directly fitted onto the hollow output shaft of the reducer, and then fixed using a keyway and a lock nut. Those skilled in the art can flexibly configure it according to actual usage requirements, which will not be described in detail here.

[0042] The above-mentioned settings can further improve the anti-clogging and anti-winding capabilities of the screw conveyor compression assembly 3, and further improve the reliability of the above-mentioned biomass waste pressing equipment during use.

[0043] In some embodiments, the variable-pitch helical blades located in the feed box of the pressing box 4 have a larger pitch at the feed end (located below the feed port) than at the discharge end. This configuration increases the initial capacity at the feed end, reducing the risk of jamming due to waste impact; it also increases the linear velocity at the discharge end, enhancing waste discharge capacity and preventing blockage.

[0044] In some embodiments, such as Figure 1 , Figure 2 As shown, a feeding funnel 2 is provided at the opening of the feeding port of the aforementioned feeding box. The opening size of the feeding end of the feeding funnel 2 is larger than the opening size of the discharging end of the feeding funnel 2, and the discharging end of the feeding funnel 2 is connected to the interior of the feeding box. It is easy to understand that the upper end of the feeding funnel 2 is the feeding end, and the lower end is the discharging end. That is, the dimension of the upper end of the feeding funnel 2 in the first direction X1 is larger than the dimension of the lower end of the feeding funnel 2 in the first direction X1. In other words, the feeding funnel 2 has a structure that is larger at the top and smaller at the bottom, and the opening size (area) of the upper end is larger than the opening size (area) of the lower end.

[0045] With the above settings, waste can be easily fed into the pressing box 4, preventing waste from scattering outside the pressing box 4 during the feeding process, ensuring environmental hygiene, and improving the practicality of the above biomass waste pressing equipment.

[0046] In some embodiments, such as Figure 1 As shown, the above-mentioned biomass waste pressing equipment also includes a push-pull assembly 8. The push-pull assembly 8 is located on the lower side of the pressing box 4, and the push-pull assembly 8 can pull the transfer box 10 so that the transfer box 10 fits against the discharge port.

[0047] Furthermore, such as Figure 3 , Figure 4 As shown, the aforementioned biomass waste pressing equipment also includes a locking hook assembly 9. This locking hook assembly 9 is disposed on both sides of the pressing box 4. It is easily understood that there can be two locking hook assemblies 9, each disposed on opposite sides of the pressing box 4. A locking groove is provided at the end of the transfer box 10 near the pressing box 4, and the locking hook assembly 9 can engage with the locking groove to lock the transfer box 10 and the pressing box 4 together.

[0048] Through the above-described configuration, the push-pull assembly 8 and the locking hook assembly 9 can enhance the firmness of the connection between the transfer box 10 and the pressing box 4, preventing the transfer box 10 from separating from the pressing box 4 during the pressing and transfer of waste, thus improving the reliability of the biomass waste pressing equipment during use. As for the specific structure of the push-pull assembly 8 and the locking hook assembly 9, relevant technologies can be referenced for design. The core improvement of this embodiment does not lie in the specific structure of the push-pull assembly 8 and the locking hook assembly 9, therefore, it will not be described in detail here.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
