Description

Technical Field

[0001] This utility model relates to the field of flooring production and processing technology, specifically a self-rotating jet dust removal device for flooring dust removal, mainly used to solve the problem that dust covering the flooring during painting after sanding affects the quality of the flooring. Background Technology

[0002] Sanding is a crucial step in flooring production, aiming to create a smooth and even surface that provides a good foundation for subsequent painting. However, sanded floors often retain a significant amount of dust. If this dust is not removed promptly, it will be covered during the painting process, leading to defects such as particles, bubbles, and pitting on the floor surface, severely impacting the floor's appearance and lifespan.

[0003] Currently, common methods for floor dust removal mainly include manual sweeping and mechanical blowing. Manual sweeping is not only inefficient and labor-intensive, but also struggles to thoroughly remove fine dust from the floor texture, resulting in inconsistent dust removal performance. Traditional mechanical blowing devices often employ linear reciprocating or multi-nozzle fixed structures, which have the following problems:

[0004] High energy consumption: Reciprocating purging devices require a drive motor to drive the nozzles to reciprocate, resulting in high energy consumption;

[0005] High air consumption: To achieve full coverage, multiple nozzles need to be installed (e.g., 8-10 nozzles are needed for a 600mm width), resulting in high compressed air consumption.

[0006] Uneven dust removal: The nozzles are fixed in arrangement, and the blowing path is repeated or missed, making it difficult to achieve uniform coverage;

[0007] Severe dust dispersion: During the purging process, dust easily spreads into the workshop, affecting the working environment and workers' health;

[0008] Low level of intelligence: It lacks real-time monitoring and adjustment of parameters such as airflow, pressure, temperature and humidity, making it difficult to adapt to different floor materials and dust residue.

[0009] Therefore, there is an urgent need for a floor dust removal device with a reasonable structure, low energy consumption, high dust removal efficiency, and strong adaptability to meet the comprehensive requirements of modern floor production lines for cleanliness, efficiency, and environmental protection.

Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0034] Please refer to Figure 1-5 , Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 for Figure 1 Structural diagram; Figure 3 This is a schematic diagram of an air knife purging device; Figure 4 for Figure 3 Internal diagram; Figure 5 for Figure 3 A schematic diagram showing the addition of a pressure sensor, flow sensor, temperature sensor, and humidity sensor.

[0035] This utility model provides a self-rotating jet dust removal device for floor dust removal. It uses the air pressure of the air knife nozzle to push the air knife back, causing it to rotate rapidly. During the conveying process, the floor is continuously and repeatedly swept by the air knife in a spiral pattern, thereby completely removing residual dust within the floor texture and directing it into the dust collection pipe. This solves the problem of dust accumulation affecting floor quality during painting after sanding. The device includes a floor conveying device 1 for conveying the floor, an air knife blowing device 2 located at the middle of the floor conveying device 1, and a dust removal device 3 connected to the air knife blowing device 2. The floor conveying device 1, air knife blowing device 2, and dust removal device 3 are electrically connected to a control cabinet 4.

[0036] The floor conveying device 1 includes a horizontally arranged conveying support 11, a conveying frame 12 horizontally arranged on the top of the conveying support 11, a conveying shaft 13 at each end of the conveying frame 12, and a rotatable conveying belt 14 arranged between the two conveying shafts 13. One end of one of the conveying shafts 13 is connected to a conveying motor 15 mounted on the conveying support 11 via a sprocket and chain drive. The conveying motor 15 drives the conveying belt 14 to rotate and convey the floor at a uniform speed. The conveying motor 15 is electrically connected to the control cabinet 4.

[0037] The surface of the conveyor belt 14 is provided with anti-slip texture, which can effectively prevent the floor from slipping during conveying and cleaning, ensuring the stability of the floor during the conveying process. In addition, the bottom of the conveying bracket 11 is provided with adjustable support feet 16. By adjusting the height of the support feet 16, the levelness of the floor conveying device 1 can be ensured to adapt to different ground conditions.

[0038] The air knife purging device 2 includes a purging protective cover 201 mounted on the conveying frame 12. The bottom edges of the two opposite side walls of the purging protective cover 201 are respectively provided with protective cover slots 202 that match the front and rear frames of the conveying frame 12, for securing the purging protective cover 201 to the conveying frame 12. A dust removal outlet pipe 203 is provided at the center of the top wall of the purging protective cover 201 and connected to the dust removal device 3 via a dust removal pipe. Purging mounting pipes 204 are respectively provided on both sides of the dust removal outlet pipe 203 on the top wall of the purging protective cover 201, and locking bolts 205 are provided through the side walls of the purging mounting pipes 204. A purging metal pipe 206 passes through the purging mounting pipe 204. The top end of the sweeping metal pipe 206 is connected to an air compressor via a control valve and an air source pipe to provide continuous compressed air for purging. The bottom end of the sweeping metal pipe 206 is connected to a rotating nozzle 208 via a rotating connector 207. The rotating nozzle 208 has multiple radially extending nozzle branches 209 evenly distributed in a ring. The end of each nozzle branch 209 is provided with a purging nozzle 210. The air outlet of the purging nozzle 210 is not vertically downward, but is deflected at the same angle to the vertical direction. Thus, during the purging process, the airflow from the purging nozzle 210 pushes the rotating nozzle 208 to rotate in a ring, thereby performing dust removal on the upper surface of the floor conveyed on the material conveyor belt 14. The control valve is electrically connected to the control cabinet 4.

[0039] The air outlet deflection angle of the blowing nozzle 210 is 30° to 60°. After multiple experiments, this angle range has been verified to enable the airflow to form an optimal spiral trajectory during the blowing process, penetrating deep into the floor texture and effectively removing dust.

[0040] In addition, the rotation speed of the rotary nozzle 208 can be adjusted by regulating the airflow pressure through a control valve according to the floor conveying speed and dust residue, so as to achieve the best dust removal effect.

[0041] The dust removal device 3 includes a dust removal fan 31. The air inlet of the dust removal fan 31 is connected to the dust removal outlet pipe 203 through a dust removal pipe. The outlet end of the dust removal fan 31 is connected to a cyclone dust collector 32 through a pipe. A dust hopper 33 is provided at the bottom of the cyclone dust collector 32. The dust removal fan 31 is electrically connected to the control cabinet 4.

[0042] The dust removal fan 31 adopts a high-efficiency and energy-saving fan, which can reduce energy consumption while ensuring sufficient air volume and air pressure. The cyclone dust collector 32 is equipped with multiple layers of cyclone separation plates. Through multi-stage cyclone separation, the dust separation efficiency is further improved, ensuring that the purified air meets environmental emission standards. The ash hopper 33 is equipped with an automatic ash discharge valve at the bottom, which can periodically discharge the collected dust to prevent dust accumulation from affecting the dust removal effect.

[0043] In addition, the inner wall of the blow-off protective cover 201 is provided with a sound-absorbing material layer, which can effectively reduce the noise generated during the blow-off process and improve the working environment of the workshop. Transparent observation windows 211 are also provided on both sides of the blow-off protective cover 201, allowing operators to observe the blow-off process and the dust removal effect on the floor in real time.

[0044] The inlet and outlet ends of the floor conveying device 1 are respectively equipped with photoelectric sensors 17 electrically connected to the control cabinet 4, which are used to detect the entry and exit of the floor and realize automated control. When the photoelectric sensor 17 detects that the floor has entered the floor conveying device, the control cabinet 4 automatically controls the start of the conveying motor 15 and the dust removal device 3; when the floor is detected to have left the conveying device 3, the relevant equipment is automatically stopped, thereby improving the automation level and energy saving effect of the equipment.

[0045] The purging metal pipe 206 is also equipped with a pressure sensor 212 and a flow sensor 213 electrically connected to the control cabinet 4, which can monitor the airflow pressure and flow rate in real time and transmit the data to the control cabinet 4. The control cabinet 4 automatically adjusts the opening of the control valve based on the data fed back by the sensors to ensure that the airflow parameters are always in the optimal state, further improving the stability and reliability of the dust removal effect.

[0046] The top of the purge protective cover 201 is equipped with a temperature sensor 214 and a humidity sensor 215, which are electrically connected to the control cabinet 4, for real-time monitoring of the temperature and humidity of the purging environment. When the ambient temperature and humidity exceed the set range, the control cabinet 4 will issue an alarm and automatically adjust the operating parameters of the dust removal fan 31 to adapt to different environmental conditions and ensure that the dust removal effect is not affected.

[0047] The air knife purging device 2 also includes an adjustable airflow distributor connected to the top of the purging metal pipes. This distributor evenly distributes compressed air to each purging metal pipe. The airflow distributor can be manually or automatically adjusted according to the floor width and dust distribution to optimize the airflow distribution ratio and further improve dust removal efficiency.

[0048] The dust removal device 3 also includes an electrostatic dust removal module installed at the outlet end of the cyclone dust collector 32. The electrostatic dust removal module applies a high-voltage electric field to charge dust particles and adsorb them onto the electrode plates, further removing fine dust particles, improving dust removal efficiency, and ensuring the cleanliness of the exhaust air.

[0049] The ash hopper 33 is equipped with a dust compactor to compact the collected dust, reducing its volume and facilitating subsequent cleaning and processing. The dust compactor is automatically controlled; when the dust level in the ash hopper reaches a certain point, the compaction operation is automatically initiated to ensure full utilization of the ash hopper's capacity.

[0050] Although embodiments of the present invention have been shown and described, it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, it will be understood by those skilled in the art that all other embodiments obtained by making various changes, modifications, substitutions and alterations to these embodiments without departing from the principles and spirit of the present invention and without creative effort are within the scope of protection of the present invention.
