Description

Technical Field

[0001] The invention relates to the technical field of dust explosion early warning, in particular to a dust explosion detection and early warning device. Background Art

[0002] In industrial production environments, dust explosions are a major hidden danger that threatens personnel safety and equipment stability. When dust concentration exceeds the standard, it is very easy to cause an explosion when exposed to open flames or high temperatures. Especially in the fields of chemical industry, metallurgy, and food processing, the rapid diffusion and local aggregation characteristics of dust make it difficult for traditional monitoring methods to capture risk sources in real time. Existing dust monitoring devices mostly use a fixed installation structure, which has the following technical bottlenecks: First, the installation process of traditional devices is complicated and requires the use of fasteners such as bolts to achieve positioning, which is difficult to adapt to frequent maintenance or rapid deployment needs; second, the single-point dust concentration detection unit has a limited coverage range and cannot effectively capture the direction of dust diffusion, resulting in delayed warnings or misjudgments; third, the dust treatment module and the detection unit are designed separately, resulting in insufficient dust adsorption, filtration and collection efficiency, making it difficult to quickly reduce local dust concentrations when risks are detected.

[0003] Furthermore, existing dust treatment devices have high maintenance costs. For example, clogged dust filters require complete disassembly and cleaning, which is cumbersome and prone to secondary dust generation. The connection between the dust collection bin and the treatment device lacks airtightness, making it prone to leakage under vibration or impact, affecting treatment effectiveness.

[0037] During installation, the dust handling device 3 is held by the operating handle 12 and moved closer to the quick mounting seat 1, so that the mounting block 2 at the upper end of the dust handling device 3 is inserted into the mounting hole 110. During this process, the first sliding groove 118 needs to be aligned with the guide block 109 respectively, and then the mounting block 2 enters the mounting hole 110, and the guide block 109 slides along the first sliding groove 118. Then, the mounting block 2 is rotated to make the guide block 109 slide horizontally along the second sliding groove 119 on one side, and then the locking groove 120 corresponds to the locking hole 116. In addition, the mounting block 2 drives the trigger block 117 at the upper end to move upward, so that the trigger The block 117 is plugged into the trigger hole 111, and the trigger rod 201 in the trigger hole 111 is slidably connected to the sliding groove 214 on the outer periphery of the trigger block 117.

The first guide slot hole 209 drives the sector gear 202 to rotate through the gear groove 213, and the sector gear 202 drives the toggle rod 203 to rotate. The end of the toggle rod 203 contacts the operating rod 205 and pushes the operating rod 205 to a certain direction. The first spring 207 pushes the limit rod 204 to move in the opposite direction, and the limit rod 204 drives the operating rod 205 to return to the initial position. During this process, one end of the limit rod 204 initially contacts the limit block 216. As the limit rod 204 moves, the limit block 216 separates from the limit rod 204. At this time, the elastic force of the coil spring 106 drives the rotating sleeve 204 to rotate. 105 rotates, and the rotating sleeve 105 drives the first rotating disk 103 and the second rotating disk 104 to rotate respectively. In the first rotating disk 103, the limit block 216 and the limit rod 204 are staggered and separated from each other, and the end of the limit rod 204 slides from one end of the inner guide groove 218 to the other end. The second rotating disk 104 drives the guide rod 107 to move along the guide groove 115. The two ends of the guide rod 107 respectively drive the locking rod 108 to move along the locking hole 116. After passing through the locking hole 116, the locking rod 108 is directly plugged into the locking groove 120. The installation and fixation of the mounting block 2 and the entire dust processing device 3 are achieved through the locking rod 108 and the locking groove 120;

[0038] When disassembly is required, the rotating sleeve 105 is rotated, and the rotating sleeve 105 drives the first rotating disk 103 and the second rotating disk 104 to rotate respectively. The second rotating disk 104 drives the guide rod 107 to move through the arc guide slot hole 114, and the guide rod 107 drives the locking rod 108 to move, so that the locking rod 108 is pulled out from the locking slot 120 and retracted into the locking hole 116, and the second rotating disk 104 drives the inner guide slot 218 and the limit block 216 to rotate, so that the limit rod 204 The stopper 216 slides along the inner guide groove 218 until the stopper 216 contacts the stopper rod 204. At this time, the stopper 216 slides into the stopper hole 219 through the inclined guide surface, so that the stopper rod 204 and the stopper 216 intersect each other. Then, the stopper 216 extends outward under the elastic force of the second spring 215, and then the rotating sleeve 105 is released. At this time, although the coil spring 106 exerts a rotational force on the rotating sleeve 105, the stopper 216 and the stopper rod 204 are in contact. The first spring 208 pushes the trigger rod 201 to move toward the center hole, and the trigger rod 201 drives the sector gear 202 to rotate in the opposite direction through the gear groove 213. The sector gear 202 drives the toggle rod 203 to rotate. The toggle rod 203 first contacts the operating rod 205, and then pushes the operating rod 205 to rotate until the toggle rod 203 and the operating rod 205 pass each other. After that, the operating rod 205 is reset under the elastic force of the torsion spring, which is convenient for ensuring smooth triggering of the device during the next installation. Finally, the installation block 2 is directly removed downward to complete the disassembly operation. In this process, the guide block 109 slides outward along the first sliding groove 118.
