Abstract
The utility model relates to a flow concentrating and damping device. Through the space design and layout of different coal dropping pipes, a flow concentrating and diversion damping plate is arranged repeatedly at different positions of conveying grooves in a coal conveying system, to ensure that when the materiel drops from the higher level of an adhesive tape to the lower level of the adhesive tape, the materiel in the conveying grooves can always flow in the influx flow state, and the induction wind is cut off thoroughly. The flow concentrating and diversion damping device is matched with a three-dimensional material dispersing and flow concentrating coal dropping pipe for use, thus the dust generated in the material conveying process is reduced greatly, the environment of the coal system is improved, the impulsion and the abrasion to the coal dropping pipe are reduced, and the service life of the device is enhanced.
Description
Affiliated technical field
The utility model relates to a kind of field coal chute systems (coal spout) such as power station, colliery that are used for and compiles the afflux damping arrangement that dispersed material cuts off the material induced air.
Background technology
In coal chute systems such as power station, colliery, because the flow at high speed of material is brought strong induced air, form malleation at material feeding point easily, cause dust to raise outward.The method that tradition is cut off induced air is in the middle of chute the buffering flapper to be set, and has certain reducing and induces wind action, but owing to material on the buffering flapper produces shar pounding usually, often cause flapper to damage, and be prone to big dust.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide the three-dimensional dispersed material afflux of a kind of cooperation coal spout spatial design layout to use, employing meets the afflux damping arrangement of coal spout structure, realizing that material compiles and cuts off induced air, and then improve the purpose of coal handling system environment.
The technical solution of the utility model is to be provided with afflux water conservancy diversion damping panel in the coal handling system chute, and afflux water conservancy diversion damping panel uses polyurethane elastomer or elastic caoutchouc to make.Make when swiftly flowing material drops down onto on the damping panel in the height fall scope in the chute, damping panel can play buffer action, with the control induced air, reduces the generation of dust.
The utility model compared with prior art, can guarantee that material is when the upper class adhesive tape drops down onto the next stage adhesive tape, in chute, can flow with the form law of compiling stream all the time, by repeat to be provided with the afflux damping arrangement at diverse location, thoroughly cut off induced air, reduce the generation of dust in the material conveying process greatly, improve the coal handling system environment, minimizing improves the service life of equipment to the impact wear of coal spout.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is the utility model structure diagram.
The specific embodiment
As shown in drawings, the utility model is porose at the diverse location of coal handling system chute 1, being convenient to afflux water conservancy diversion damping panel 2 inserts, damping panel 2 can be as required, diverse location at chute 1 repeats to be provided with, the inclination angle of the vertical direction of damping panel 2 and chute 1 is between 45 degree-60 degree, and thickness is the 15-30 millimeter, and being installed in chute (coal spout) afflux water conservancy diversion damping panel 2 can change from the outside easily; The material of damping panel 2 can use polyurethane elastomer or elastic caoutchouc to make.By at different coal spout spatial design layouts, adopt afflux water conservancy diversion damping panel 2, when can guarantee that material passes through smoothly, cut off the induced air more than 90%.
Claims (2)
1, a kind of afflux damping arrangement comprises chute (1), it is characterized in that: be provided with afflux water conservancy diversion damping panel (2) in the chute (1).
2, afflux damping arrangement according to claim 1 is characterized in that: described afflux water conservancy diversion damping panel (2) uses polyurethane elastomer or elastic caoutchouc to make.
