Abstract
The utility model discloses a gas spray screen-cleaning device for a vibrating screen. The gas spray screen-cleaning device for the vibrating screen comprises a shell and is characterized in that a pipe shaft is vertically arranged in the shell by a bearing pedestal; the middle part of the pipe shaft is hermetically connected with the shell; the shell is communicated with a gas inlet connector; at least one high-pressure spray pipe is connected with the upper end of the pipe shaft and the bottom surface of the screen in parallel; gas nozzles are uniformly distributed on the spray pipes and above the moving direction of taking the pipe shaft as the center; a fixed disc is arranged on the side wall of the lower part of the shell; and the high-pressure spray pipes are distributed uniformly in the straight-line shape or cross shape. The gas spray screen-cleaning device for the vibrating screen sprays and blows the screen by the high-pressure gas so as to effectively prevent or reduce mesh blockage which can influence the screening efficiency and the yield. The gas spray screen-cleaning device for the vibrating screen finishes rotation action by the reacting force of gas spray to achieve the effect of completely cleaning the screen without power. The gas spray screen-cleaning device for the vibrating screen has the advantages of simple structure, low cost and wide application range.
Description
Technical field:
The utility model relates to screening, particularly a kind of be used to be installed in below the screen cloth will glue with gases at high pressure get lodged in the jet clear net arrangement of oscillating riddle that the light material on the screen cloth cleans out.
Background technology:
Existing vibratory sieve, its clear net mode mainly are with the elasticity of ball screen cloth to be produced vibration, and sticking light material and the irregular particle that gets lodged on the screen cloth shaken, and move away with the material that did not have to net, and reach anti-blocking purpose.The problem that exists is the influence that receives equipment operation form and dress mesh number because of ball, and it is not ideal enough to net effect clearly, rolls net clearly if use brush instead; Then need change the internal structure of equipment; And the increase power source, character and the requirement of explosion proof to the screening material increased difficulty again simultaneously, not only influences screening efficiency; Also increase cost, also limited the scope of application simultaneously.
Summary of the invention:
The purpose of the utility model provides a kind of simple in structure, the jet clear net arrangement of oscillating riddle that screening efficiency is high, cost is low.
The technical scheme of the utility model is accomplished as follows; It includes a casing, it is characterized in that: in casing, be vertically installed with a tubular axis up and down with bearing block, the middle part of tubular axis is connected with the casing inner sealing; Be communicated with an inlet suction port on the casing; Parallelly with the screen cloth bottom surface in the upper end of tubular axis being connected with at least one high-pressure nozzle, is that the center is evenly equipped with puff prot respectively in direction of motion back upper place with the tubular axis on the jet pipe, on the lower sides of casing, is provided with a fixed disk.High-pressure nozzle is that in-line or cross are evenly arranged.
The utility model reaches the purpose that effectively prevents or reduce mesh congestion affects screening efficiency and output through gases at high pressure winding-up screen cloth.And accomplish rotatablely moving of self by jet reaction force, obtain exempting from the clear comprehensively net effect of power.Has advantage simple in structure, that cost is low, applied widely.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing; The utility model is in a casing 4, to be vertically installed with a tubular axis 3 up and down with bearing block 7; The middle part of tubular axis is connected with the casing inner sealing, is communicated with an inlet suction port 5 on the casing, the parallel high-pressure nozzle 2 that is fixedly connected with a cross layout with the screen cloth bottom surface in the upper end of tubular axis; Be that the center is evenly equipped with puff prot 1 respectively in the back upper place of the direction of motion with the tubular axis on the jet pipe, on the lower sides of casing, be provided with a fixed disk 6.During installation, as long as this device is installed on the sieve lattice below the screen cloth, inlet suction port is connected with high-pressure pump, promptly available gases at high pressure carry out net clearly.Jet pipe is accomplished rotation automatically during clear the net under jet reaction force promotes, and reaches comprehensive clear net, can prevent or reduce the obstruction of screen cloth effectively, improves screening efficiency, and is applied widely.
