Description

Technical Field

[0001] The utility model relates to the field of biomass particle production, in particular to a biomass particle production dust removal device. Background Art

[0002] Biomass pellets are made of agricultural and forestry waste, such as wood chips and straw, and are made into fuel that can be directly burned through processes such as crushing, mixing, extrusion, and drying. It is a clean fuel that can replace coal. During processing, the biomass raw materials are first crushed, and then the crushed biomass raw materials are conveyed to a screening machine, where the coarse materials and impurities are separated, and then the fine materials are conveyed to the biomass fuel processing unit through a biomass raw material conveyor belt. However, in the existing biomass pellet preparation process, the biomass pellets contain a large amount of dust. If the dust is not screened and processed, it is easy to cause equipment blockage and damage the equipment, and the dust floating in the air will have a certain impact on the human respiratory system.

[0003] In a Chinese patent, a dust removal device for biomass pellet production is disclosed, and its patent number is CN216323378U. In the patent, a dust removal device for biomass pellet production includes: a shell, an S-shaped hollow plate, an electric fan, an exhaust fan, a filter bin, a filter screen and a water tank. The shell is provided with an S-shaped hollow plate, the upper end of the S-shaped hollow plate is connected with a feed pipe, and the end of the feed pipe away from the S-shaped hollow plate is provided with a feed hopper, and the feed hopper is connected with an exhaust pipe on the side close to the S-shaped hollow plate. The biomass pellets poured into the feed hopper will undergo the first dust removal. The S-shaped hollow plate in the dust removal device can make the biomass pellets have a longer falling stroke and a larger diffusion area during the dust removal process, so as to more effectively remove the dust in the biomass particles. The electric fan at the bottom of the dust removal device can blow the dust impurities in the biomass pellets to the upper part of the device, and the exhaust fan at the top of the device will extract the dust impurities, and after being filtered in the filter bin, they will enter the water tank for further filtration, and then enter the air, which will not cause pollution to the environment.

[0004] The above-mentioned published patents have the following disadvantages:

[0005] (1) In the prior art, when the number of biomass particles inside the equipment is too large, they will accumulate inside, and some dust contained in the biomass particles is difficult to be screened out, and will eventually be discharged from the equipment together with the biomass particles, affecting the dust removal effect of the dust removal equipment.

[0006] (2) In the prior art, the dust collected together will adhere to the inner wall of the collection box because some particles are relatively fine, and need to be manually cleaned. If it is not cleaned for a long time, it will accumulate on the inner wall and affect the subsequent normal use of the equipment. Utility Model Content

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 6 As shown, a biomass particle production dust removal device includes a shell 1, and a support leg 2 is fixed on the bottom surface of the shell 1 to support the shell 1. The biomass particles enter the shell 1 through the feed port 3 fixed on the upper surface of the shell 1, so that they can fall on the receiving plate 401 at the bottom of the supporting frame 4 just below the feed port 3. The discharge pipe 403 arranged on the surface of the receiving plate 401 can facilitate the discharge of the biomass particles. The vibration component 5 on the bottom surface of the receiving plate 401 is provided with a driving motor 502 to drive the connecting rod 503 to rotate, so that the rotating member 504 at the middle position of the connecting rod 503 can rotate eccentrically, and the connecting tube 505 at the upper end of the rotating member 504 can make The linkage rod 1 506 on the inside drives the linkage rod 2 508 above to vibrate up and down, so that the receiving plate 401 at the upper end of the linkage rod 2 508 can vibrate the biomass particles to disperse them, and the two blowers 6 located on both sides of the vibration component 5 can blow the dust vibrated upwards, and the discharge port 7 located on one side of the surface of the shell 1 is provided with a valve body 701 to control the discharge of the biomass particles, and the dust collecting component 8 fixedly connected to the upper end of the surface of the shell 1 is provided with a dust extractor 804 so that the dust can pass through it into the inside of the connecting pipe 803, and then enter the dust collecting box 802 inside the connecting frame 801 at the other end through the connecting pipe 803 for unified collection.

[0028] A plurality of air holes 402 arranged in a circular array are arranged around the receiving plate 401 with a high surrounding surface and a low slope in the middle.

[0029] Through the above technical solution, under the setting of the slope structure, the biomass particles can be concentrated in the middle position of the receiving plate 401 as much as possible to facilitate subsequent vibration, and under the setting of the air hole 402, the wind blown by the hair dryer 6 can blow the dust upwards through it for easy collection.

[0030] The circumferential diameter of the discharge pipe 403 located inside the discharge port 7 is smaller than the circumferential diameter of the discharge port 7 .

[0031] Through the above technical solution, the discharge pipe 403 located at one side of the supporting frame 4 can discharge the biomass particles when the supporting frame 4 vibrates up and down, so that it can be connected with the discharge port 7 to avoid leakage of the biomass particles.

[0032] The vibration component 5 is set to a fixed frame 501 fixed on the inner side of the shell 1, so that the driving motor 502 can drive the connecting rod 503 to rotate, so that the spring 507 can be fixed between the semicircular structure at the bottom end of the linkage rod 1 506 and the connecting tube 505, and the linkage rod 2 508 slides on the inner side of the fixing ring 509 on the surface of the fixed frame 501.

[0033] Through the above technical solution, under the drive of the driving motor 502, the connecting tube 505 can drive the linkage rod 1 506 to move up and down under the elastic force of the spring 507, so that the linkage rod 1 506 can drive the biomass particles on the surface of the receiving plate 401 to vibrate through the linkage rod 2 508 at its upper end.

[0034] The dust collecting box 802 slidably connected inside the connection frame 801 fixedly connected to the surface of the shell 1 can drive the dust collecting net 823 on the surface to rotate by the rotation rod 821 inside the limiting ring 822.

[0035] Through the above technical solution, the dust collecting net 823 can be driven to rotate under the drive of the rotating rod 821, ensuring that the dust collecting net 823 can collect dust particles that enter the dust collecting box 802 through the connecting pipe 803.

[0036] The multiple ventilation holes on the surface of the dust collecting net 823 can easily collect internal dust, and one end of the dust collecting net 823 is a conical structure that fits the inner wall of the dust collecting box 802.

[0037] Through the above technical solution, with the setting of the conical structure at one end of the dust collecting net 823, it can be used to scrape off the dust particles adhering to the inner wall of the dust collecting box 802, making it more convenient and quick for the user to clean the dust collecting box 802.

[0038] When in use, when the user uses the biomass particle production dust removal equipment, the user puts the biomass particles into the inner side of the shell 1 through the feed port 3 so that they can fall on the receiving plate 401, starts the driving motor 502, and through the rotation of the connecting rod 503, the eccentrically connected rotating member 504 can drive the connecting cylinder 505 to vibrate up and down during the rotation process, so that under the control of the elastic force of the spring 507, the linkage rod 1 506 can drive the linkage rod 2 508 to vibrate up and down to ensure that the surface of the receiving plate 401 is smooth. The material particles can vibrate and shake out the dust inside them, and cooperate with the hair dryer 6 on the surface of the fixed frame 501 to allow the wind to blow out through the air vents 402, causing the dust to float upward and be absorbed by the dust extractor 804, enter the inner side of the dust box 802 through the connecting pipe 803, and be adsorbed by the dust collecting net 823. After the adsorption work is completed, the dust box 802 is pulled out from the inner side of the connecting frame 801, and the adhering dust is cleaned by rotating the rotating rod 821 and using one end of the dust collecting net 823 attached to the inner wall of the dust box 802.
