Description

Technical Field

[0001] This utility model relates to the field of biomass fuel processing technology, specifically to a dust removal device for a biomass fuel production workshop. Background Technology

[0002] Biomass fuel is made from materials such as wood chips, straw, waste wood, branches, and bark. It can be used as fuel for boilers for power generation and heating. Actively utilizing biomass fuel has significant social and economic benefits. However, dust is generated during biomass fuel production activities such as crushing, conveying, and pelleting. This dust permeates the workshop, resulting in a harsh working environment.

[0003] A patent document with publication number CN219880885U discloses a workshop dust removal device, including a dust collection hood and a suspension frame for adjusting the dust collection hood. The suspension frame includes a fixed frame, a transverse screw is rotatably mounted inside the fixed frame, a crossbar is threaded onto the transverse screw, a longitudinal screw is rotatably mounted at the bottom of the crossbar, a movable seat is threaded onto the longitudinal screw, an electric push rod is fixedly mounted at the bottom of the movable seat, and the dust collection hood is fixedly mounted at the lower end of the electric push rod.

[0004] However, the above-mentioned device has the following problems when in use;

[0005] When existing dust collection devices are used inside workshops, the dust collection hoods are generally conical and non-removable, resulting in a fixed absorption area. This makes it impossible to optimize the arrangement for different types of biomass raw materials and the characteristics of dust during processing, thereby reducing the efficiency of dust capture. Furthermore, the fixed-size dust collection hoods may not be able to effectively cover all pollution sources, causing some dust to escape into the environment without being captured, affecting the use of the equipment. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the prior art. It proposes a dust removal device for a biomass fuel production workshop. The size of the dust collection hood can be adjusted by simply moving the two moving plates closer or further apart. This allows for a tighter coverage of the pollution source, reducing dust dispersion, improving dust capture efficiency, adapting to different processing conditions and dust characteristics, and enhancing the flexibility of the entire dust removal system.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A dust removal device for a biomass fuel production workshop includes a body, on which a corrugated hose is installed;

[0009] An adjustment tube is provided at the other end of the corrugated hose, and an installation plate is fixedly installed at the other end of the adjustment tube;

[0010] A support column is fixedly installed on the mounting plate, and a fixing frame is fixedly installed on the other end of the support column. A dust collection pipe is fixedly installed on the fixing frame, and the dust collection pipe is connected to the corrugated hose.

[0011] Both sides of the fixed frame are fixedly installed with accordion covers, and each end of the two accordion covers opposite to the fixed frame is fixedly installed with a movable plate.

[0012] The fixed frame is equipped with a drive mechanism that allows the movable plate to move, and a drive mechanism that is compatible with the drive mechanism.

[0013] Preferably, the driving mechanism includes two fixed blocks, two racks and a driven gear. The fixed blocks are fixedly mounted on the movable plate and are fixedly connected to the racks. The driven gear is rotatably mounted on the fixed frame and is meshed with both racks.

[0014] Preferably, the drive device includes a drive gear, which is rotatably mounted on a fixed frame. A connecting rod is fixedly mounted at the center of the drive gear, and a handwheel is fixedly mounted on the connecting rod.

[0015] Preferably, the driving gear and the driven gear are in a meshing relationship.

[0016] Preferably, limit blocks are fixedly installed on both sides of the two movable plates, and sliders are fixedly installed on the side of the limit blocks facing the fixed frame. The support column has a groove at the corresponding position for the slider to move.

[0017] Preferably, the machine body is provided with a support member, which is adapted to the corrugated hose.

[0018] Preferably, casters are fixedly installed at the bottom of the machine body.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention incorporates an organic body, corrugated hose, adjusting pipe, mounting plate, support column, fixing frame, dust collection pipe, accordion hood, moving plate drive mechanism, and driving mechanism. By simply moving the two moving plates closer or further apart, the accordion hood can be retracted or expanded. Consequently, the length of the entire structure (i.e., dust collection hood) consisting of the fixing frame, moving plate, and accordion hood can be varied, and the size of the dust collection hood can be adjusted according to actual needs. This allows for tighter coverage of the pollution source, reduced dust dispersion, improved dust capture efficiency, adaptation to different processing conditions and dust characteristics, and enhanced flexibility of the entire dust removal system.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Please see Figures 1 to 5 A dust removal device for a biomass fuel production workshop includes a body 1, on which a corrugated hose 3 is installed. The corrugated hose 3 can be easily bent and is suitable for dust removal activities that require frequent changes in direction. The corrugated hose 3 can be extended or shortened within a certain range, providing greater flexibility for dust removal operations.

[0029] An adjusting tube 5 is provided on the other end of the corrugated hose 3, and an mounting plate 6 is fixedly installed on the other end of the adjusting tube 5.

[0030] The angle of the adjusting pipe 5 can be changed so that the dust collection hood installed on it can be changed at the same angle and can be stably positioned at the corresponding angle, which can be used for different application needs.

[0031] A support column 7 is fixedly installed on the mounting plate 6. A fixing frame 8 is fixedly installed on the other end of the support column 7. A dust collection pipe 9 is fixedly installed on the fixing frame 8. The dust collection pipe 9 is connected to the corrugated hose 3. The dust inside the dust collection hood is absorbed through the dust collection pipe 9 and then transported to the inside of the machine body 1 through the corrugated hose 3 to realize the dust treatment activity.

[0032] Both sides of the fixed frame 8 are fixedly installed with accordion covers 10, and each end of the two accordion covers 10 away from the support column 7 is fixedly installed with a movable plate 11.

[0033] By moving the two movable plates 11 closer to or further apart from each other, the accordion cover 10 can be retracted or expanded. As a result, the length of the whole (i.e., the dust collection cover) consisting of the fixed frame 8, the movable plates 11 and the accordion cover 10 can be changed. That is, the size of the dust collection cover can be adjusted according to actual needs, making it more convenient for daily use.

[0034] The fixed frame 8 is equipped with a drive mechanism that allows the movable plate 11 to move and a drive mechanism that is compatible with the drive mechanism.

[0035] The drive mechanism allows the two movable plates 11 to move closer or further apart to achieve adjustment, and the driving mechanism enables the drive mechanism to operate normally.

[0036] The driving mechanism includes two fixed blocks 12, two racks 13 and a driven gear 14. The fixed blocks 12 are fixedly mounted on the movable plate 11 and are fixedly connected to the racks 13. The driven gear 14 is rotatably mounted on the fixed frame 8 and is meshed with both racks 13.

[0037] By rotating the driven gear 14, which meshes with both racks 13, the rotation of the driven gear 14 can smoothly drive the two racks 13 to move closer or further apart, thereby allowing the two movable plates 11 to move synchronously. This enables the bellows cover 10 to retract or expand, facilitating daily use.

[0038] The drive unit includes a drive gear 16, which is rotatably mounted on a fixed frame 8. A connecting rod 17 is fixedly mounted at the center of the drive gear 16, and a handwheel 18 is fixedly mounted on the connecting rod 17.

[0039] The driving gear 16 and the driven gear 14 are in a meshing relationship.

[0040] When the handwheel 18 is manually rotated, the rotation of the handwheel 18 causes the drive gear 16 to rotate synchronously. In turn, the drive gear 16, through meshing, causes the driven gear 14 to rotate normally, thus completing the drive mechanism.

[0041] Limiting blocks 15 are fixedly installed on both sides of the two movable plates 11. Slider blocks 19 are fixedly installed on the side of the limiting blocks 15 facing the fixed frame 8. The support column 7 has a groove 20 at the corresponding position for the sliding block 19 to move.

[0042] When the movable plate 11 moves, the slider 19 moves synchronously inside the slide groove 20. The presence of the limiting block 15 ensures that the movable plate 11 can only move in one direction, and also ensures the consistency and stability of the moving plate 11's running direction.

[0043] The body 1 is provided with a support member 4, which is adapted to the corrugated hose 3. The support member 4 can deflect synchronously with the adjustment of the corrugated hose 3 to ensure the stability of the bending of the corrugated hose 3. Since it is existing technology and has been implemented on the corresponding equipment, the disclosure is sufficient, so it is not described in detail here.

[0044] The bottom of the machine body 1 is fixedly equipped with casters 2, which allow the equipment to be moved as a whole, so that it can be used in different locations in the workshop.

[0045] The working process of this utility model is as follows: First, the equipment is pushed to the corresponding position, and then the size of the dust collection hood is adjusted according to actual needs.

[0046] The handwheel 18 is manually rotated, which causes the drive gear 16 to rotate synchronously. The drive gear 16 then meshes with the driven gear 14, which rotates normally. The rotation of the driven gear 14 smoothly drives the two racks 13 to move closer or further apart, thus moving the two movable plates 11 synchronously. This allows the bellows cover 10 to retract or expand. As a result, the length of the whole structure (i.e., the dust collection cover) consisting of the fixed frame 8, the movable plates 11, and the bellows cover 10 can be changed, meaning the size of the dust collection cover can be adjusted according to actual needs, making it more convenient for daily use.

[0047] Then, by operating the corrugated hose 3 and the adjusting pipe 5, the angle of the dust collection hood installed on it is changed synchronously, so that the whole (i.e., the dust collection hood) consisting of the fixed frame 8, the moving plate 11 and the bellows cover 10 is stably in the optimal angle. The dust inside the dust collection hood is absorbed by the dust inlet pipe 9 and then transported to the inside of the machine body 1 through the corrugated hose 3, thus realizing the dust treatment activity.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
