Description

Technical Field

[0001] The utility model relates to the field of biomass fuel processing, in particular to a biomass pressing device. Background Art

[0002] Biomass includes plants, animals and microorganisms. In a broad sense, biomass includes all plants, microorganisms, animals that feed on plants and microorganisms, and their waste products. Representative biomass includes crops, crop waste, wood, wood waste and animal manure.

[0003] Biomass pellet fuel is actually the direct combustion of biomass energy, which is the processing and utilization of biomass. Direct combustion methods can be divided into four types: stove combustion, boiler combustion, garbage combustion and solid fuel combustion. Among them, solid fuel combustion is a newly promoted technology. It solidifies biomass into a shape and then uses traditional coal-fired equipment to burn it. Its advantages are that it makes full use of biomass energy to replace coal, reduces CO2 and SO2 emissions, is beneficial to environmental protection and controls greenhouse gas emissions, slows down climate change, and reduces the occurrence of natural disasters. In the process of biomass pellet fuel production, a compaction device is required.

[0004] Prior art such as publication number: CN215551148U discloses a compacting device for biomass pellet fuel processing. In order to solve the problem that the compacting device generally only performs compression from top to bottom during use, so that the compressed material will be squeezed outward, resulting in insufficient compression and affecting the processing of biomass pellet fuel, hydraulic push rods and push plates are arranged on both sides of the workbench. When the raw materials are compressed inside the workbench, part of the raw materials are compressed to the edge of the workbench. The hydraulic push rod pushes the push plate, the return spring and the baffle to push the raw materials to the middle of the workbench for re-compression.

[0005] In the above-mentioned prior art, although the baffle pushed by the hydraulic push rod can push and compact the raw materials scattered on both sides of the workbench inward, the holding plate that moves downward to compact the material will also be affected by the height of the baffle when falling and cannot fall to the bottom, affecting the compaction of the biomass material. For this reason, we propose a biomass pressing device. Utility Model Content

[0006] The purpose of the utility model is to provide a biomass pressing device to solve the problems raised in the above background technology.

[0008] Further: the compacting mechanism includes a base plate, which is fixedly connected to the movable end of the hydraulic cylinder B, a spring is fixedly connected to the bottom of the inner wall of the base plate, and a movable plate is fixedly connected to the upper end of the spring, and the cross-sectional shape of the movable plate is an inverted U shape.

[0010] Furthermore: a material storage bin is arranged at the bottom of the frame on the lower side of the rotating shaft, and a material retrieval bin door connected to the material storage bin is arranged on the outer wall of the frame close to the bottom.

[0011] Furthermore, the length of the bottom plate and the length of the movable plate close to the inner side of the pressing frame are matched with the width of the inner wall of the pressing frame.

[0012] Furthermore: side panels are provided on both sides of the outer wall of the inner frame near the bottom, and rounded corners are provided on the inner wall edge where the inner frame contacts the pressure frame.

[0013] Furthermore: the length of the side panel matches the height of the inner frame.

[0015] 1. In the utility model, when the pressing platform is pressed down, the movable plate can move down and will not become an obstacle to the descent of the pressing platform. When the pressing platform leaves the pressing frame, the movable plate can be reset under the action of the spring in the bottom plate.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 , the figure shows a preferred embodiment of the utility model, a biomass pressing device, including a frame 1, a hydraulic cylinder A2 is fixedly installed on the top of the frame 1, the movable end of the lower end of the hydraulic cylinder A2 is fixedly connected to the pressing platform 3, the inner side of the frame 1 is fixedly connected to the pressing frame 4 below the pressing platform 3, hydraulic cylinders B5 are fixedly installed on both sides of the outer wall of the pressing frame 4, the movable end of the hydraulic cylinder B5 is provided with a compacting mechanism 6 for pushing materials on both sides inward, and the inner side of the pressing frame 4 is provided with a movable mechanism 7 for assisting material discharge.

[0023] Specifically, the compacting mechanism 6 includes a base plate 8, which is fixedly connected to the movable end of the hydraulic cylinder B5. A spring 9 is fixedly connected to the bottom of the inner wall of the base plate 8, and a movable plate 10 is fixedly connected to the upper end of the spring 9. The cross-sectional shape of the movable plate 10 is an inverted U shape. When the press platform 3 is pressed down, the movable plate 10 can move downward and will not become an obstacle to the descent of the press platform 3.

[0024] Specifically, the movable mechanism 7 includes an inner frame 11, the bottom of the inner frame 11 is fixedly connected to a rotating shaft 12, the rotating shaft 12 is rotatably connected to the inside of the frame 1, and one end of the rotating shaft 12 extends from the inside of the frame 1 and is fixedly connected to a turntable 13; after the pressing is completed, when the pressing table 3 and the compacting mechanism 6 are away from the pressed material, the inner frame 11 is flipped over by the turntable 13 and the rotating shaft 12, and the pressed material can be taken out. It should be noted that a counterweight block is provided at the bottom center of the inner frame 11, so that the upper side of the inner frame 11 that matches the pressing frame 4 can be located on the upper side and stacked with the pressing frame 4 without external force.

[0025] Among them, a storage bin is set at the bottom of the frame 1 on the lower side of the rotating shaft 12 for storing the pressed materials that fall down after the inner frame 11 is turned over, and a material retrieval bin door 14 connected to the storage bin is set on the outer wall of the frame 1 near the bottom for subsequent material retrieval.

[0026] The length of the bottom plate 8 and the length of the movable plate 10 close to the inner side of the pressing frame 4 are matched with the inner wall width of the pressing frame 4, so that when the compacting mechanism 6 moves toward the material, the material can be completely pushed inward.

[0027] Among them, side panels are provided on both sides of the outer wall of the inner frame 11 near the bottom to block the path of the inner frame 11 when it is flipped and prevent debris from falling into the storage bin. Rounded corners are provided on the inner wall edge where the inner frame 11 contacts the pressure frame 4 to make the compacting mechanism 6 smoother when passing through the intersection.

[0028] The length of the side panels matches the height of the inner frame 11, making the structure of the device more stable.

[0029] In this embodiment, the biomass material to be pressed is placed on the upper surface of the inner frame 11 inside the pressing frame 4. When pressing, the hydraulic cylinder A2 and the hydraulic cylinder B5 are started to compress the material downward and inward respectively to compact the material. Compared with the prior art, when the pressing platform 3 is pressed down, the movable plate 10 can move down and will not become an obstacle to the descent of the pressing platform 3. When the pressing platform 3 leaves the pressing frame 4, the movable plate 10 can be reset under the action of the spring 9 in the bottom plate 8. The relative movement of the two sets of compacting mechanisms 6 combined with the downward movement of the movable plate 10 enables the device to complete the pressing of the material when the material is small, and is not affected by the amount of material, so that the storage material can be pressed more fully.

[0030] After the pressing is completed, when the pressing table 3 and the compacting mechanism 6 are away from the pressed material, the inner frame 11 is flipped through the turntable 13 and the rotating shaft 12, so that the pressed material can be poured into the storage bin for storage. After releasing the turntable 13, the inner frame 11 is reset under the action of the counterweight block. When taking out the materials in batches, it is only necessary to open the bin door 14.
