Technical Field
[0001] This utility model relates to the field of pipe cutting technology, and in particular to a dust negative pressure collection device for cutting phosphogypsum pipes. Background Technology
[0002] In the field of pipe cutting technology, due to the material characteristics of phosphogypsum pipes, a large amount of dust and debris are easily generated during the cutting process. Traditional phosphogypsum pipe cutting operations mostly adopt an open operation mode, lacking effective dust control and collection methods, which causes the dust generated during cutting to spread directly into the working environment.
[0003] These dust particles not only pollute the air, but also harm the health of operators when inhaled, and long-term exposure can easily lead to respiratory and other related diseases. At the same time, dust adhering to the surface of cutting equipment will affect the normal operation accuracy and service life of the equipment, and increase the maintenance cost of the equipment. To address these issues, we propose a negative pressure dust collection device for phosphogypsum pipe cutting. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] like Figures 1-5 As shown, the present invention proposes a negative pressure dust collection device for cutting phosphogypsum pipes, including a side pipe 1, a side pipe 2, an annular box 7, a base plate 10, a motor 11, and a motor 2 14. The side pipe 1 and the side pipe 2 are arranged above the base plate 10. A closed cover 3 is provided at one end of the side pipe 2. A negative pressure pipe 4 connected to a negative pressure dust removal device is embedded inside the closed cover 3. An annular box 7 is provided on one side of the side pipe 1. Inner pipes 28 arranged in a ring array are embedded in the inner wall of the annular box 7. A guide rail 8 is symmetrically distributed at the upper end of the base plate 10. A slider 13 is slidably installed on the outer wall of the guide rail 8 at the lower end of both the side pipe 1 and the side pipe 2. A screw hole 12 is opened inside the slider 13. A motor 11 is provided at the upper end of the base plate 10. A screw rod 9 with relatively distributed threads on the outer wall and threadedly inserted into the screw hole 12 is provided at the output end of the motor 11. A hydraulic rod 6 is installed inside the upper end of the side tube, and a bracket 16 is installed at the lower end of the hydraulic rod 6 inside the upper end of the side tube. A motor 15 is installed inside the bracket 16, and a cutting wheel 5 is installed at the output end of the motor 15. Multiple sets of oil pipes 17 for internal pressure regulation are provided at one end of the ring box 7. A guide rail 18 is provided on one inner wall of the side tube 1, and a slider 19 is provided at one end of the ring box 7 and is slidably installed on the outer wall of the guide rail 18. A motor 14 is installed on one inner wall of the side tube 1, a nut 21 is installed at one end of the slider 2 19, and a screw 20 is installed at the output end of the motor 2 14 and threadedly inserted into the nut 21. The inner tube 28 is equipped with a sliding piston 22, one end of which is provided with a stopper rod 24, and the other end of the stopper rod 24 is provided with a clamping block 27. The inner wall of the inner tube 28 is provided with symmetrically distributed support rings 25. A sealing ring 26 is embedded in the support ring 25. The piston rod 24 is slidably installed inside the sealing ring 26. A spring 23 is provided between the support ring 25 and the piston 22 and sleeved on the outside of the piston rod 24.
[0017] Based on the implementation steps of Embodiment 1: Start motor 11. Motor 11 drives the screw to rotate. Since the threads on the outer wall of the screw are relatively distributed and respectively engage with the threaded holes 12 of the lower sliders 13 of side tube 1 and side tube 2, the rotation of the screw will drive side tube 1 and side tube 2 away from each other along the guide rail 8, making the device open and facilitating the operator to place the phosphogypsum pipe. Pass one end of the phosphogypsum pipe to be cut through the inside of the ring box 7. Adjust the pipe diameter through the oil pipe 17 at one end of the ring box 7. The pressure inside the joint ring box 7 changes, which pushes the piston 22 in the inner tube 28 to move. The piston 22 drives the piston rod 24 and the clamping block 27 to move towards the pipe until the clamping block 27 is tightly attached to the outer wall of the pipe. At the same time, the spring 23 between the support ring 25 and the piston 22 in the inner tube 28 is compressed. The reaction force of the spring 23 further enhances the clamping force of the clamping block 27 on the pipe, realizing the stable fixation of the phosphogypsum pipe. Moreover, the clamping blocks 27 distributed in a ring array can ensure that the pipe is subjected to uniform force and avoid the deformation of the pipe during the clamping process.
[0018] Motor 14 is started, driving screw 20 to rotate. Screw 20 engages with nut 21 at one end of slider 19, driving slider 19 to move along guide rail 18. This, in turn, moves ring box 7 and the clamped phosphogypsum pipe. The operator, by observing or using the positioning marks on the equipment, adjusts the position of the pipe to be cut directly below cutting wheel 5, achieving precise positioning. Motor 15 is then started, driving cutting wheel 5 to rotate at high speed. Subsequently, hydraulic rod 6 is extended, pushing bracket 16, motor 15, and cutting wheel 5 downwards. Cutting wheel 5 contacts phosphogypsum pipe, initiating the cutting operation. During the cutting process, the extension speed of hydraulic rod 6 can be finely adjusted according to the cutting progress to ensure a smooth cutting process. Simultaneously, the external negative pressure dust removal equipment connected to negative pressure pipe 4 is activated. Negative pressure is generated in the relatively enclosed space formed by side pipe 1, side pipe 2, and closed cover 3 within negative pressure pipe 4. Dust and debris generated during cutting are drawn into negative pressure pipe 4 under negative pressure and then transported to external dust removal equipment for collection and treatment, thus preventing dust from spreading into the working environment.
[0019] After cutting, first control the hydraulic rod 6 to retract, driving the cutting wheel 5 upward to detach from the pipe. Turn off the motor 15, and the cutting wheel 5 stops rotating. Then, adjust the internal pressure of the ring box 7 through the oil pipe 17, causing the piston 22 to reset under the action of the spring 23, driving the stopper rod 24 and the clamping block 27 away from the pipe, releasing the clamp on the pipe, and the operator can remove the cut pipe. Finally, motor 11 is started, driving side tube 1 and side tube 2 to move away from each other along guide rail 8, returning to the initial open state, preparing for the next cutting operation. With the cooperation of motor 214, screw 20, slider 219 and guide rail 218, the ring box 7 and the pipe can be moved smoothly and accurately. The pipe cutting position can be quickly adjusted to be directly below the cutting wheel 5, with high positioning accuracy, effectively ensuring the accuracy of the cutting size, reducing cutting errors, and improving the quality of pipe cutting. The hydraulic rod 6 can flexibly adjust the up and down movement speed and position of the cutting wheel 5 to adapt to the cutting needs of phosphogypsum pipes of different thicknesses and hardnesses. Moreover, the cutting wheel 5 driven by motor 315 has a stable rotation speed and high cutting efficiency, which can quickly complete the pipe cutting operation and improve the overall work efficiency.
[0020] The clamping structure, consisting of an inner tube 28, piston 22, stopper rod 24, and clamping block 27 arranged in a ring array, works in conjunction with the pressure adjusted by the oil pipe 17 and the reaction force of the spring 23 to apply clamping force evenly from all sides of the pipe, ensuring its stable fixation and preventing displacement or shaking during cutting. Simultaneously, the sealing ring 26 ensures the sealing of the inner tube 28, guaranteeing the stability of pressure regulation and further enhancing clamping reliability. Excessive clamping force will not cause pipe deformation, protecting the pipe's appearance and structural integrity. Side tubes 1 and 2 can close together under the drive of motor 11 and the screw, forming a relatively sealed cutting space with the closing cover 3, reducing dust diffusion channels. The negative pressure pipe 4 connects to the external... When used in conjunction with dust collection equipment, a stable negative pressure is generated in a confined space, which can comprehensively and quickly suck up and collect the dust and debris generated during cutting. The dust collection rate is high, effectively improving the air quality of the working environment and reducing the impact of dust on the health of operators. The operation of the entire device is achieved by controlling the start, stop and movement of motor 11, motor 24, motor 315 and hydraulic rod 6. The operation process is simple and easy to understand. Operators can become proficient in operating the device after simple training, reducing the difficulty of operation and labor intensity. The clamping range of the clamping structure can be adjusted to adapt to the cutting of phosphogypsum pipes of different diameters. Furthermore, the height and moving speed of the cutting wheel 5 can be flexibly adjusted according to the characteristics of the pipe, making it widely applicable and able to meet various cutting needs.
[0021] Traditional phosphogypsum pipe cutting operations are mostly carried out in open environments. The large amount of dust generated during cutting spreads into the surrounding work environment, polluting the air and being inhaled by operators, seriously endangering their health. Furthermore, dust adhering to the equipment surface can affect the normal operation and lifespan of the equipment. This embodiment uses side pipe 1, side pipe 2, and a closed cover 3 to form a relatively enclosed space. Combined with the negative pressure collection function of the negative pressure pipe 4, dust is quickly collected, effectively solving the dust diffusion problem, protecting the working environment and the health of operators, and reducing the adverse effects of dust on the equipment. In traditional cutting methods, operators often rely on experience to manually adjust the pipe cutting position. Low positioning accuracy easily leads to deviations in cutting dimensions, resulting in a high scrap rate of pipes, wasting raw materials, and increasing production costs. This embodiment uses an adjustment mechanism composed of motor 214, screw 20, slider 219, and guide rail 218 to achieve precise adjustment of the pipe cutting position. The positioning error is small, which greatly improves the accuracy of the cutting dimensions, reduces the scrap rate of pipes, saves raw materials, and reduces production costs. In the traditional cutting process, the fixing method of the pipe is relatively simple, often using simple clamps or manual support. The fixing is not firm, and the pipe is prone to displacement and shaking during cutting, resulting in an uneven cutting surface, affecting the subsequent use of the pipe, and may even cause safety accidents. The ring array clamping structure of this embodiment can clamp the pipe uniformly from multiple directions, with stable and reliable clamping force. It effectively avoids pipe deviation and shaking during the cutting process, ensures a flat cutting surface, improves pipe quality, and reduces the risk of safety accidents. The height of the cutting wheel 5 is automatically adjusted by the hydraulic rod 6, and the motor drives the automatic positioning of the pipe and the stable rotation of the cutting wheel 5. The various operation links are smoothly connected, reducing manual operation time and significantly improving cutting efficiency, which can meet the needs of large-volume phosphogypsum pipe cutting operations.
