[0001] This utility model relates to the field of industrial pipeline auxiliary equipment technology, and in particular to an anti-clogging and dust prevention device for lime spraying pipelines. Background Technology

[0002] In industrial production, lime is often transported in powder form via pipelines for processes such as desulfurization and neutralization reactions.

[0003] However, existing lime spraying pipelines have some problems. When using lime spraying pipelines, workers first need to connect the lime connecting pipe to the spraying pipeline to facilitate the delivery of lime into the spraying pipeline. At the pipeline connection point, lime powder is prone to leakage, generating a large amount of dust, which not only pollutes the working environment and endangers the health of operators, but also causes material waste, poor sealing effect, and increases production costs. Therefore, an anti-clogging and dust prevention device for lime spraying pipelines is designed for improvement and upgrading. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5As shown in the figure, this embodiment provides a design for an anti-clogging and dustproof device for a lime spraying pipe, including a spraying conduit 1. A lime spraying head 2 is fixedly installed at one end of the spraying conduit 1. A connecting pipe 6 is fixedly inserted inside the spraying conduit 1. A lime connecting pipe 3 is installed above the connecting pipe 6. A sealing structure 5 is provided between the lime connecting pipe 3 and the connecting pipe 6. The sealing structure 5 includes a connecting seat 51 fixedly installed at the upper end of the connecting pipe 6. A sealing gasket 53 and a rubber sealing ring 54 are respectively installed inside the connecting seat 51. A snap ring 55 is fixedly installed at the bottom of one end of the lime connecting pipe 3. A first clamp 56 and a second clamp 57 are respectively fitted on the outer walls of the lime connecting pipe 3 and the connecting seat 51. A protrusion 58 is fixedly installed at one end of both the first clamp 56 and the second clamp 57. A fastening screw 582 is threadedly connected inside the two protrusions 58. A spiral conveying blade 71 is rotatably installed inside the spraying conduit 1, and a heating wire 8 is fitted inside the spraying conduit 1.

[0024] like Figures 3 to 4 As shown, a solenoid valve 61 is fixedly installed on the outer wall of the connecting pipe 6. A dustproof groove 52 is opened inside the connecting seat 51. The sealing gasket 53 and the rubber sealing ring 54 are both fixedly installed inside the dustproof groove 52. The snap ring 55 is adapted to the size of the dustproof groove 52. The lime connecting pipe 3 and the connecting seat 51 are pressed and aligned with each other. One end of the first clamp 56 is fixedly connected to a limit rod 59. The limit rod 59 is rotatably installed inside the second clamp 57. One end of the fastening screw 582 is fixedly installed with an anti-slip knob 581. A hexagonal nut 583 is fixedly installed on the outer wall of the protrusion 58 at one end of the second clamp 57. The fastening screw 582 is threadedly connected inside the hexagonal nut 583.

[0025] By setting a snap ring 55 at the bottom of the lime connecting pipe 3 to squeeze the sealing gasket 53 and rubber sealing ring 54 of the connecting seat 51 on the connecting pipe 6, the lime connecting pipe 3 and the connecting seat 51 are relatively sealed to prevent lime leakage. At the same time, a first clamp 56 and a second clamp 57 are set on the outside to lock and wrap the gap. Then, the fastening screw 582 is rotated in the hexagonal nut 583 to facilitate further locking and sealing of the connection part, improving the double sealing guarantee. Meanwhile, a dust curtain 41 is set on the outside of the maintenance flange 4. The dust curtain 41 is made of wear-resistant and dustproof canvas material, which can effectively block dust from overflowing, and will not affect the normal operation of valves and maintenance ports.

[0026] like Figure 5As shown, inspection flanges 4 are symmetrically fixed on the outer wall of the injection duct 1. Dustproof curtains 41 are fitted into the gaps of the outer walls of the two inspection flanges 4. Temperature sensors 9 are fixedly installed on the outer wall of the injection duct 1. A positioning shaft is fixedly installed in the middle of the spiral conveying blade 71, and one end of the positioning shaft is fixedly connected to the drive motor 7. The drive motor 7 is fixedly installed inside the injection duct 1. Heating wire 8 is spirally sleeved on the inner wall of the injection duct 1. One end of the heating wire 8 is fixedly installed on the control circuit board 10. The control circuit board 10 is fixedly installed on the outer wall of the injection duct 1.

[0027] The drive motor 7 rotates the spiral conveying blades 71 on the positioning shaft to push the lime, effectively preventing local accumulation and blockage. At the same time, the temperature sensor 9 monitors the pipe temperature. By connecting the power supply to the control circuit board 10, the heating wire 8 is activated to heat the inner wall of the pipe, effectively preventing the lime from drying out and clumping. Starting from one end of the pipe, the heating wire 8 is evenly and tightly wound around the outer wall of the pipe, maintaining a consistent winding direction to avoid crossing, overlapping, or messy situations. The power cord of the heating wire 8 is connected to the control circuit board 10. During the connection process, the electrical wiring diagram must be strictly followed to ensure that the live wire, neutral wire, and ground wire are connected correctly to prevent poor contact. The temperature sensor 9 is a commonly used thermocouple temperature sensor, which has advantages such as good linearity, large thermoelectric potential, high sensitivity, good stability and uniformity, strong oxidation resistance, and relatively low price.

[0028] The working principle and process of this utility model are as follows: First, when lime needs to be sprayed and conveyed, the operator aligns the clamping ring 55 at one end of the lime connecting pipe 3 with the connecting seat 51 on the connecting pipe 6, causing the clamping ring 55 to press against the rubber sealing ring 54 and sealing gasket 53 in the dustproof groove 52, thus causing the lime connecting pipe 3 and the connecting seat 51 to align and seal against each other. At the same time, by rotating the limiting rod 59 on the first clamp 56 within the second clamp 57, the gap between the connecting seat 51 and the lime connecting pipe 3 is locked and wrapped. Finally, by rotating the anti-slip knob 581, the fastening screw 582 is rotated within one of the protrusions 58, causing its extension end to lock and fix with the hexagonal nut 583 on the other protrusion 58, facilitating further sealing of the lime connecting pipe 3 and the connecting seat 51. To prevent lime leakage and pollution, dust curtains 41 are installed on the outer walls of both inspection flanges 4 to effectively prevent dust from overflowing. After the lime connecting pipe 3 and the connecting pipe 6 are sealed and connected, the spiral conveying blades 71 on the positioning shaft are rotated by the drive motor 7. The spiral blades push the lime powder towards the lime spray head 2. Even if local accumulation occurs, the agitation and pushing by the spiral blades can prevent blockage. While pushing the lime, the temperature sensor 9 on the spray pipe monitors the process. When the temperature sensor 9 detects that the temperature inside the pipe is lower than the set value, the external power supply is turned on, and the heating wire 8 is activated through the control circuit board 10 to heat the inner wall of the pipe, increase the temperature inside the pipe, prevent the lime from getting damp and clumping, and further reduce the possibility of blockage.
