Description
Technical Field
[0001] This utility model belongs to the field of dust suppressant mixing technology, and in particular, a dust suppressant mixing device for railway coal transportation. Background Technology
[0002] Railway coal transportation requires spraying dust suppressants onto the coal surface. Before application, the dust suppressant powder needs to be mixed with water using a mixing device. Existing mixing devices often use direct mixing without considering the position of the dust suppressant powder and water introduced into the mixing tank. This results in the dust suppressant and water not coming into rapid and uniform contact, reducing the mixing efficiency of the mixing device.
[0003] A search of related technologies revealed a Chinese patent document (authorization announcement number CN214811839U) entitled "Immediate Mixing and Spraying Device for Dust Suppressant in Railway Coal Transportation," which includes an immediate mixing device and a spraying device. The immediate mixing device is used to immediately mix water and powder and transmit them to the spraying device. The spraying device, connected to the immediate mixing device, receives the dust suppressant transmitted by the immediate mixing device and sprays it to a designated location. Compared with existing technologies, this invention eliminates the need for a traditional storage mixing tank, achieving immediate spraying through simultaneous mixing and spraying. However, this device does not consider controlling the position of the dust suppressant powder and water introduced into the mixing tank, resulting in insufficient rapid and uniform contact between the dust suppressant powder and water when introduced into the mixing tank, thus reducing the mixing efficiency of the mixing device for the dust suppressant powder and water. Utility Model Content
[0004] The purpose of this invention is to provide a dust suppressant mixing device for railway coal transportation to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust suppressant mixing device for railway coal transportation, comprising:
[0006] A mixing tank for dust suppressants used in railway coal transportation, wherein the inner cavity of the mixing tank is equipped with several mixing plates for dust suppressants used in railway coal transportation.
[0007] A dust suppressant guiding assembly for railway coal transportation includes two hollow mounting rods and two inclined nozzles. The top wall of the mixing tank is rotatably connected to the two mounting rods via bearings. The outer periphery of the nozzles is connected to the mounting rods. Toothed rings are fitted onto the sides of the mounting rods. The top surfaces of the two mounting rods are respectively connected to conduit one and conduit two via bearings. Toothed rings mesh with toothed plates. Connecting plates are welded to adjacent sides of the two toothed plates. T-shaped connectors are welded to the sides of the connecting plates. The moving part of a linear motor is bolted to the side of the connectors.
[0008] Preferably, the fixed end of the linear motor is connected to the mixing tank by bolts, and the lower part of both the first and second conduits is provided with a bracket.
[0009] Preferably, the bottom surfaces of the two supports are welded to the mixing tank, and a rotary motor and a discharge port with a solenoid valve are respectively installed on the bottom and side surfaces of the mixing tank.
[0010] Preferably, the output shaft of the rotary motor is connected to a hollow rotating rod via a coupling, and the inner wall of the rotating rod is rotatably connected to several pairs of vertically arranged connecting rods via bearings.
[0011] Preferably, each pair of connecting rods is welded to the stirring plate on the opposite side, and a bevel gear is welded to the adjacent side of each pair of connecting rods.
[0012] Preferably, two bevel gears mesh with a second bevel gear, and a fixed rod is rotatably connected to the top surface of the rotating rod via a bearing.
[0013] Preferably, the top surface of the fixing rod is welded to the mixing tank, and the bottom surface of the fixing rod is connected to a transmission rod.
[0014] Preferably, the two top surfaces of several bevel gears are all embedded and fixedly connected to the transmission rod.
[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0016] This railway coal transportation dust suppressant mixing device introduces dust suppressant powder and water into the mixing tank through conduit one and conduit two, respectively, so that the dust suppressant powder and water are mixed in the mixing tank. A linear motor provides power, and with the connection of the connecting parts and connecting plates, the two toothed plates move laterally. Under the meshing of the toothed plates and toothed rings, the two mounting rods rotate, which in turn drives the rotation of the inclined nozzles. This increases the position of the dust suppressant powder and water sprayed by the two nozzles in the mixing tank, realizes the rapid and uniform mixing of dust suppressant powder and water, and improves the mixing efficiency of the mixing device for dust suppressant powder and water.
[0017] This railway coal transport dust suppressant mixing device uses a rotary motor for power. The output shaft of the motor rotates, driving a rotating rod, which in turn rotates several mixing plates around the rotating rod. This provides conditions for mixing the dust suppressant powder and water in the mixing tank. With a fixed connection between the fixed rod and the transmission rod, each bevel gear II meshes with two bevel gear I, causing several pairs of connecting rods to rotate. This allows several mixing plates to rotate around the rotating rod, and simultaneously, the mixing plates can rotate around the connecting rod, achieving the mixing and tumbling of the dust suppressant powder and water inside the mixing tank, thus improving the mixing effect of the dust suppressant powder and water.

The moving part of the linear motor 13 moves, and under the connection of the connector 12 and the connecting plate 11, the two toothed plates 10 move synchronously and in the same direction. During the transmission process, the two nozzles 5 can rotate and move, increasing the range of dust suppressant powder and water sprayed, so that the dust suppressant powder and water are mixed quickly, and improving the mixing efficiency of the mixing device for the dust suppressant powder and water.
[0032] The fixed end of the linear motor 13 is connected to the mixing tank 1 by bolts. Both the first guide tube 7 and the second guide tube 8 are equipped with supports 9 at their lower parts. Each support 9 is formed by a combination of a support rod and a U-shaped support plate. The top surface of the support rod is welded to the support plate, and the inner wall of the support plate abuts against either the first guide tube 7 or the second guide tube 8, thus supporting and fixing the first guide tube 7 and the second guide tube 8. The bottom surfaces of the two supports 9 are welded to the mixing tank 1. A rotary motor 16 and a discharge port 14 with a solenoid valve are respectively installed on the bottom and side surfaces of the mixing tank 1.
