Description

Technical Field

[0001] This utility model relates to the technical field of dust removal devices for green plastering mortar production, and in particular to a dust removal device for green plastering mortar production. Background Technology

[0002] For example, CN223351307U describes a dust removal device for green plastering mortar production. It uses a double-headed suction pipe to suck up dust generated during raw material pouring and mixing, and combines this with water spraying to suppress dust from the filter screen. However, it has the following problems: 1. The dust that is inhaled is generated when the raw materials are poured in and when the mixture is stirred at the feed inlet. The vast majority or even all of it is dust raised by the raw materials. After being suppressed by water spraying, it is difficult to reuse it. 2. Spraying water on the filter screen during the dust removal process can cause the collected raw materials to stick to it, making the filter screen difficult to clean. 3. Although the filter cylinder can be easily disassembled and assembled, the device cannot work during disassembly and assembly, which affects work efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a dust removal device for green plastering mortar production to address the aforementioned technical problems.

[0004] To achieve the above objectives, this utility model provides a dust removal device for green plastering mortar production, including a frame, a turntable rotatably mounted on the frame, a plurality of filter screens slidably engaged on the turntable, a drive block rotatably mounted on the filter screens, the drive block having a drive groove, a movable frame slidably engaged on the frame, a rotary drive device mounted on the movable frame, a square block mounted on the output end of the rotary drive device, the square block cooperating with the drive groove, a stirring component mounted on the drive block, a ratchet mounted on the turntable, a drive wheel rotatably mounted on the turntable, a pawl mechanism mounted on the drive wheel, and the square block being drively connected to the pawl mechanism.

[0005] Preferably, an arc-shaped baffle is installed on the turntable, and when the filter cylinder rotates to the position directly below the spraying mechanism, the arc-shaped baffle is located directly above the filter cylinder.

[0006] Preferably, it also includes a suction pipe, which is mounted on the frame and has a sealing plug installed on it. The sealing plug is slidably connected to the end of the filter cylinder away from the drive block.

[0007] Preferably, the ratchet mechanism includes an elastic element and an abutment element. The elastic element is mounted on the drive wheel, and the abutment element is rotatably mounted on the drive wheel. The output end of the elastic element abuts against the abutment element.

[0008] Preferably, a gear reducer is installed on the frame, a drive wheel is installed inside the gear reducer, a square block is slidably engaged with the drive wheel, and the output end of the gear reducer is connected to the pawl mechanism for transmission.

[0009] Preferably, a shaped component is installed inside the filter cylinder, and the end of the stirring component away from the drive block is rotatably mounted on the shaped component.

[0010] Compared with existing technologies, this technical solution has at least one of the following beneficial effects: 1. The rotating drive device drives the stirring component to rotate, so that the collected raw materials can be continuously stirred, thus avoiding the problem that the raw materials on the outer side are constantly sprayed with water and are easy to stick together and cannot be reused. 2. By setting up several filter cylinders on the turntable, the collected filter cylinders can be rotated to other positions for disassembly and recycling, while another filter cylinder can continue to perform dust removal work. 3. By using a ratchet and pawl mechanism, the rotary drive can drive the mixing component and the turntable to rotate separately, thus reducing production costs. Attached Figure Description

Detailed Implementation

[0012] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0013] Please see Figures 1 to 3This application provides a dust removal device for green plastering mortar production, including a frame 1. A turntable 2 is rotatably mounted on the frame 1. The turntable 2 is a cylindrical structure composed of two discs and several fixed rods connecting the two discs. Several filter cylinders 3 are slidably engaged on the turntable 2. The filter cylinders 3 can be slidably engaged with the turntable 2 through a slot-block structure. A circular through hole is provided at a corresponding position on the frame 1. When the filter cylinder 3 rotates to this position, it can connect to the dust suction pipe. A drive block 4 is rotatably mounted on the filter cylinder 3. The drive block 4 has a drive groove 5. A movable frame 6 is slidably engaged on the frame 1. A rotary drive device 7 is fixedly mounted on the movable frame 6. The rotary drive device 7 can be customized to a lower cost. A servo motor with a rotational speed and connected to an external signal processor has a square block 8 fixedly installed at the output end of a rotary drive device 7. The square block 8 is configured to cooperate with the drive groove 5. An agitator 9 is fixedly installed on the drive block 4. The agitator 9 is preferably a plurality of alternately arranged inclined scrapers as described in this application. The inclined scrapers can be set to a fixed inclination angle to collect dust to the middle of the filter cylinder 3. The agitator 9 in the middle can be scraped without setting an angle. The agitator 9 needs to be in contact with the inner wall of the filter cylinder 3. A ratchet 10 is fixedly installed on the turntable 2. A drive wheel 11 is rotatably installed on the turntable 2. A plurality of pawl mechanisms 12 are installed on the drive wheel 11. The square block 8 is always connected to the pawl mechanism 12 in a transmission.

[0014] In this embodiment, the ratchet 10 on the turntable 2 and the pawl mechanism 12 on the drive wheel 11 enable the rotary drive device 7 to drive the pawl mechanism 12 via the square block 8, thereby driving the entire turntable 2 to rotate. This allows several filter cylinders 3 on the turntable 2 to be rotated to suitable positions. When one of the filter cylinders 3 rotates to the appropriate dust removal position, the moving frame 6 can drive the rotary drive device 7 to move forward, allowing the square block 8 to be inserted into the drive groove 5 in the drive block 4 on the filter cylinder 3. Afterward, the rotary drive device 7 drives the drive block 4 to rotate in the opposite direction, so that the pawl mechanism 12 can no longer drive the ratchet 10 and the turntable 2 to rotate, but the stirring component 9 can be driven to rotate via the drive block 4. The agitator 9 continuously tumbles the collected raw material dust, preventing the outermost material from constantly contacting the filter cylinder 3. This reduces the likelihood of the material condensing when exposed to water mist, facilitating recycling and making the filter cylinder 3 easier to clean. Once the filter cylinder 3 is collected, the moving frame 6 drives the rotary drive device 7 and the square block 8 to retract and separate from the drive block 4. When the rotary drive device 7 drives the agitator 9 to agitate, it continuously drives the drive wheel 11 to rotate. To facilitate precise rotation of the turntable 2 by the drive wheel 11, the drive wheel 11 needs to be rotated to the initial position at the start of agitation. Regular maintenance can be performed to determine the accuracy of the drive wheel 11's rotation position.

[0015] In some embodiments, to further prevent material adhesion within the filter cylinder 3, an arc-shaped baffle 13 is fixedly installed on the turntable 2. When the filter cylinder 3 rotates to a position directly below the spray mechanism, the arc-shaped baffle 13 is positioned directly above the filter cylinder 3. This allows the water mist sprayed by the spray mechanism to be blocked by the arc-shaped baffle 13, while dust escaping from the filter cylinder 3 with the airflow will dissipate from the bottom of the arc-shaped baffle 13. This further prevents adhesion and does not affect dust suppression. Filter cylinders 3 in other positions can still be radiated by water mist, but less water mist will adhere to them.

[0016] In some embodiments, a suction pipe 14 is provided to facilitate dust removal. The suction pipe 14 is mounted on the frame 1, and a sealing plug 20 is fixedly installed on the suction pipe 14. The sealing plug 20 can be a rubber plug, and it is slidably connected to the end of the filter cylinder 3 away from the drive block 4. Thus, before dust removal, the sealing plug 20 can be slid into the filter cylinder 3, and the dust is then transported into the filter cylinder 3 by the suction pump through the suction pipe 14. When replacing the filter cylinder 3, the sealing plug 20 can be removed and rotated for replacement. The end of the filter cylinder 3 away from the rotary drive device 7 is in an open state that abuts against the inner wall of the frame 1. The dust collected therein may enter the gap between the frame 1 and the turntable 2, but the turntable 2 only needs to be able to rotate relative to the frame 1 and be supported by the frame 1. It does not require extremely high rotational precision, so it will not cause a significant impact. The water level in the frame 1 should be below the turntable 2.

[0017] In some embodiments, to achieve engagement between the ratchet 10 and the pawl mechanism 12, the pawl mechanism 12 includes an elastic element 15 and an abutment element 16. The elastic element 15 may be a spring, and it is fixedly mounted on the drive wheel 11. The abutment element 16 is rotatably mounted on the drive wheel 11, and the output end of the elastic element 15 abuts against the abutment element 16. Thus, the elastic element 15 can push the abutment element 16 out to engage with the ratchet 10, while in the reverse rotation, the abutment element 16 will compress the elastic element 15.

[0018] In some embodiments, to ensure that the rotary drive device always drives the pawl mechanism 12 to rotate, a gear reducer 17 is fixedly mounted on the frame 1. A drive wheel 18 is rotatably mounted inside the gear reducer 17. The square block 8 is slidably engaged with the drive wheel 18, and the output end of the gear reducer 17 is drive-connected to the pawl mechanism 12. Therefore, regardless of whether the square block 8 is engaged in the drive slot 5, the square block 8 is always rotating, driving the rotating wheel 18 to rotate, thus ensuring that the gear at the output end of the gear reducer 17 is always drive-connected to the pawl mechanism 12.

[0019] In some embodiments, to facilitate the stable rotation of the agitator 9, a shaped component 19 is fixedly installed inside the filter cylinder 3, and the end of the agitator 9 away from the drive block 4 is rotatably mounted on the shaped component 19. The collected dust can pass through the gaps in the shaped component 19.

[0020] The fixed connection and rotating installation in the above embodiments can all be achieved by welding, screw fasteners and other forms in the prior art, and the rotating installation can be achieved by bearings, circular rotating blocks and circular grooves. All of the above components are standard parts, and those that are not standard parts can also be specially customized, so the inventor will not elaborate further.

[0021] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0022] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
