Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mineral transportation, in particular to dust reduction equipment for a belt conveyor. Background Art
[0002] A belt conveyor is a mechanical device that uses friction to continuously transport materials. It can be used to convey materials along a specific conveyor line, from the initial feed point to the final discharge point, creating a continuous material flow. It can transport both bulk materials and finished items.
[0003] Belt conveyors are used to transport minerals during mining. Due to the height difference in mining, multiple belt conveyors are usually required to cooperate. At the height difference, a large amount of dust will be generated when the ore falls. Spray mechanisms are usually set on the left and right sides of the belt conveyor to reduce dust through water mist. However, the water mist will cover the belt conveyor, causing the metal parts of the belt conveyor to come into contact with water too much, accelerating corrosion. For this reason, we propose a belt conveyor dust reduction device. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a belt conveyor dust reduction device, which can effectively solve the problems in the background technology by leading the generated dust out of the belt conveyor and then spraying and settling it, thereby slowing down the corrosion of the belt conveyor.
[0005] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: a belt conveyor dust reduction device, comprising a dust cover;
[0006] Dust cover: There is a skylight on the upper end. The upper end of the front skylight is connected to the feed pipe by bolts, and the upper ends of the other skylights are connected to the dust reduction pipe by bolts. The left side of the dust reduction pipe is fixedly connected to the inside with a spray pipe, and the lower ends of the spray pipes are fixedly connected with connecting pipes. The generated dust is led out of the belt conveyor and then sprayed and settled, which slows down the corrosion of the belt conveyor.
[0007] Furthermore, the lower end of the left side of the dust reduction pipe is connected to a wastewater collection trough by bolts, and the wastewater collection trough is used to collect wastewater.
[0008] Furthermore, a control switch is included. The left side of the dust cover is provided with a control switch. The input end of the control switch is electrically connected to an external power supply to control the fan to turn on.
[0009] Furthermore, it also includes a negative pressure mechanism, which includes an exhaust duct and a fan. The exhaust duct is arranged on the front side of the wastewater collection tank at the front side. The front side of the exhaust duct is fixedly connected to the fan. The input end of the fan is electrically connected to the output end of the control switch to create a negative pressure environment inside the wastewater collection tank.
[0010] Furthermore, the negative pressure mechanism also includes a sedimentation plate. The lower end of the vertical pipe of the exhaust duct is fixedly connected with the sedimentation plates symmetrically distributed front and back. The sedimentation plates are all located inside the exhaust duct to reduce the erosion of water mist on the fan.
[0011] Furthermore, the rear side of the dust cover is connected with evenly distributed shielding strips through bolts, and the lower ends of the shielding strips located on the same dust cover form an inverted trapezoidal structure to block dust.
[0012] Furthermore, sealing plates are fixedly connected to the inner walls on both sides of the dust cover, and cooperate with the two ends of the belt to perform sealing.
[0013] Furthermore, an observation window is hingedly provided on the right side of the dust cover to facilitate observation of the internal situation of the dust cover.
[0014] Compared with the prior art, the beneficial effects of the present invention are: the dust reduction equipment for belt conveyors has the following advantages:
[0015] The belt conveyor dust reduction equipment is installed on the belt conveyor at the lower end of the drop position. The ore transported by the belt conveyor falls from the feed pipe into the belt conveyor at the lower end. Most of the raised dust is inside the dust cover. The fan exhausts air to form a negative pressure environment inside the wastewater collection tank. The dust is sucked into the wastewater collection tank from the dust reduction pipe. At the same time, a part of the dust floating on the upper end of the feed pipe is also sucked in, reducing the dust floating outside the drop position. The spray pipe sprays water mist, and the water mist combines with the dust and falls into the inside of the wastewater collection tank. The dust is removed by leading the dust out of the upper end of the belt conveyor, which avoids excessive contact between the belt conveyor and the water mist, slows down the corrosion of various components, and extends the service life.

The lower ends of the shielding strips 5 located on the same dust cover 1 form an inverted trapezoidal structure. The inner walls on both sides of the dust cover 1 are fixedly connected with sealing plates 8. The right side of the dust cover 1 is hinged with an observation window 1 by a hinge 0, the dust is sucked into the wastewater collecting tank 3 from the dust suppression pipe 2, and the dust floating on the upper end of the feed pipe 7 is also partially sucked in, reducing the dust floating outside the drop position, and the spray pipe 4 sprays water mist, which combines with the dust and falls into the inside of the wastewater collecting tank 3. A water diversion trough can be opened at the water outlet position of the wastewater collecting tank 3 to collect wastewater. The left and right ends of the belt of the belt conveyor are respectively pressed on the upper ends of the adjacent sealing plates 8 to achieve the sealing of the left and right ends of the belt to prevent dust from being blown out from the lower end of the dust cover 1.
