Description

Technical Field

[0001] The utility model belongs to the technical field of screw conveyors, and in particular relates to a screw conveyor capable of reducing dust. Background Art

[0002] During the ex situ thermal desorption process for remediation of contaminated soil, the exhaust gas from the rotary kiln needs to pass through a cyclone dust removal device to remove fine soil particles in the exhaust gas. Since the contaminated soil becomes completely dry after being burned in the rotary kiln, the exhaust gas contains a large number of extremely fine soil particles that need to be collected by a screw conveyor.

[0003] However, there are some problems with the existing technology: when the existing screw conveyor collects and transports the soil particles removed from the exhaust gas by the cyclone dust collector, due to the fine and dry particle size of the soil particles, a large amount of dust will be generated at the conveyor outlet, causing air pollution. When the screw conveyor on the construction site generates a large amount of dust, in order to avoid serious air pollution, it is sometimes necessary to suspend the equipment and stop production and use manual dust reduction and cleaning to reduce production efficiency and increase resource and manpower costs. Therefore, we propose a screw conveyor that can reduce dust. Utility Model Content

[0004] In response to the problems existing in the existing technology, the purpose of this utility model is to provide a spiral conveyor that can reduce dust. By opening the air particle monitoring equipment and the water pipe valve, the monitoring equipment will automatically monitor the particle concentration at the outlet of the spiral box. When it exceeds the set value, the nozzle will be controlled to automatically spray to reduce the smoke and dust concentration in the box. When it reaches below the set value, the nozzle will be automatically controlled to close.

[0030] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 6 As shown, an embodiment of the present invention provides a spiral conveyor capable of reducing dust, comprising:

[0032] The conveyor body 1 is composed of a motor 101, a screw rod 102, a spiral blade 103 and a spiral shell box 104. The spiral blade 103 is fixedly sleeved on the surface of the screw rod 102. The screw rod 102 is rotatably arranged in the spiral shell box 104, and the screw rod 102 is connected to the output shaft of the motor 101. The spiral shell box 104 is cylindrical. An air particle monitoring device 9 is provided above the discharge port of the spiral shell box 104. Two sets of first rotating seats 2 are fixedly installed at both ends of the surface of the spiral shell box 104. , both groups of first rotating seats 2 are rotatably provided with jackets 3, one group of jackets 3 is fixedly installed with a first connecting plate 4, and the other group of jackets 3 is fixedly installed with a second connecting plate 10, the upper surface of the first connecting plate 4 is provided with a snap assembly 5, and the upper surface of the second connecting plate 10 is fixedly installed with a fixing block 6, and the snap assembly 5 is used to fix the fixing block 6; water pipe 7, the water pipe 7 is arranged between the two groups of jackets 3, and three groups of nozzles 8 are fixedly connected to the surface of the water pipe 7, and three groups of water inlet holes are opened on the surface of the spiral shell box 104, and the three groups of nozzles 8 are respectively located in the three groups of water inlet holes.

[0033] Soil particles enter from the feed port at the protruding end of the spiral housing box 104, and the output shaft of the motor 101 rotates to drive the screw rod 102 to rotate, and the rotation of the screw rod 102 drives the spiral blade 103 to rotate, so that the soil particles are transported to the outlet, and the smoke concentration of the soil particles is monitored in real time by the air particle monitoring device 9 arranged above the outlet of the spiral housing box 104. After reaching the set value, the nozzle 8 is automatically controlled to start spraying inside the spiral housing box 104, thereby reducing the smoke concentration in the spiral housing box 104. When the smoke concentration at the outlet of the screw conveyor drops to the limit value, the nozzle 8 is automatically closed. The present invention can effectively reduce the smoke generated by the cyclone dust removal auger screw conveyor during operation by ectopic thermal desorption, prevent the equipment from generating secondary pollution, and can greatly improve the production efficiency of the equipment and reduce resource and labor costs;

[0034] When it is necessary to fix the nozzle 8 in the water inlet hole, the water pipe 7 is set in the two groups of jackets 3 and drives the nozzle 8 to be inserted into the water inlet hole, and then the two groups of jackets 3 are rotated relative to each other by the first rotating seat 2 to clamp the water pipe 7, and the rotation of the two groups of jackets 3 also brings the first connecting plate 4 and the second connecting plate 10 together. When they are fitted together, the snap assembly 5 is then operated to fix the fixing block 6 by the snap assembly 5, thereby preventing the two groups of jackets 3 from separating, thereby achieving the effect of fixing the position of the water pipe 7 by the jacket 3, and the water pipe 7 is fixed by the jacket 3, thereby achieving the effect of the nozzle 8 being fixed in the water inlet hole, so that the nozzle 8 can spray water into the spiral shell box 104 through the water inlet hole, and the jacket 3 is conveniently fixed in the position of the water pipe 7 through the snap assembly 5, and water is introduced into the nozzle 8 through the water pipe 7, and the nozzle 8 is an atomizing nozzle 8.

[0035] A through slot is provided on the upper surface of the fixing block 6 , and a buckle slot is provided at one end of the through slot.

[0036] Specifically, the snap assembly 5 includes a fixed frame 501, the lower surface of the fixed frame 501 is fixedly mounted on the upper surface of the first connecting plate 4; two groups of sliding rods 502 are fixedly mounted in the fixed frame 501; a slider 503, one end of the slider 503 is provided with two groups of sliding holes, and the two groups of sliding holes are slidably sleeved on the surfaces of the two groups of sliding rods 502; a push rod 508 is fixedly mounted on one side of the slider 503, and the other end of the slider 503 is elastically connected to two groups of return springs 505, and one end of the two groups of return springs 505 are jointly fixedly mounted on one end of the fixed frame 501; a second rotating seat 504 is fixedly mounted on the upper surface of the slider 503, and a third connecting plate 507 is rotatably arranged in the second rotating seat 504, and a snap block 506 is fixedly mounted on one side of the protruding end of the third connecting plate 507, and the protruding end of the third connecting plate 507 is inserted into the through slot, and the snap block 506 is inserted into the snap slot.

[0037] The staff pushes the push rod 508 toward the fixed block 6, thereby driving the slider 503 to slide on the surface of the slide rod 502. The sliding of the slider 503 drives the return spring 505 to compress and drive the third connecting plate 507 to move above the through-slot opening. When the third connecting plate 507 moves above the through-slot opening, the third connecting plate 507 then rotates toward the through-slot through the second rotating seat 504. After the protruding end of the third connecting plate 507 is inserted into the through-slot, it also drives the buckle block 506. When the locking block 506 is in alignment with the locking groove, the staff will loosen the pull rod. Due to the force of the reset spring 505, one end of the locking block 506 will be inserted into the locking groove to fix the fixed block 6. The staff will push the push rod 508 toward the fixed block 6 again to move the locking block 506 out of the locking groove. Then, the third connecting plate 507 will be rotated to drive the locking block 506 to move out of the through slot, so that the fixed block 6 will not be fixed.
