A kind of material handling channel seal structure
Technical field
The present invention relates to the sealing configuration field of material handling passage, relate in particular to a kind of sealing and the material handling channel seal structure that reduces suction air volume that is applied to the raising production line of Treatment of Metal Surface production line.
Background technique
At some Treatment of Metal Surface production lines, like tunnel type wire acid cleaning production line, need the Abgasabsaugung in the whole production line be handled, will guarantee relative sealing.But in order to guarantee the handling of material, it is longer just to have a length, the handling passage of certain opening width; If can not this channel seal or sealing effect is poor; Even use the very big suction air volume of an one magnitude can not waste gas be siphoned away, and loss to production line pollutes working environment.Like present domestic stainless steel tunnel type wire acid cleaning production lines of much having built, be employed on the middle opening of handling passage hairbrush is set, thereby play the effect of sealing; But working life is short, fragile; Cause effect relatively poor, Production Regional has acid mist to overflow, and haves much room for improvement.
Summary of the invention
The present invention is directed to the deficiency of existing technology, a kind of good sealing effect is provided, long service life effectively prevents the material handling channel seal structure that waste gas escapes.
The present invention is for solving the problems of the technologies described above; Following technological scheme is provided: a kind of material handling channel seal structure, comprise handling passage, handling appliance, described handling appliance is installed on the handling passage; Leave one tunnel opening that is used for to held suspension line cable in the middle of the handling passage; It is characterized in that the handling appliance rear and front end respectively is provided with a sealing system, described sealing system is made up of takers-in, pressure roller, corrosion-resistant belt, and described takers-in, pressure roller are arranged at handling appliance end, corresponding described handling passage middle opening one on the other; Corrosion-resistant belt one end is fixed on the takers-in, and the other end is walked around pressure roller and is fixed in handling passage one end.
For better explaining technological scheme of the present invention; Below introduce working principle of the present invention in detail: the sealing system that a cover is made up of takers-in, pressure roller, corrosion-resistant belt respectively is installed in the rear and front end of handling appliance; Corrosion-resistant belt one end is fixed on the takers-in; The other end is walked around an end that is fixed in handling appliance behind the pressure roller, by pressure roller corrosion-resistant belt and handling passage is adjacent to.When handling appliance at handling passage one end when the other end is advanced; The corrosion-resistant belt of the sealing system of handling appliance one end slowly launches to be covered on the middle opening of handling passage along with advancing; The corrosion-resistant belt of the sealing system of the handling appliance the other end is along with advancing slowly rolling-in on takers-in; Make the handling passage utilize corrosion-resistant belt to seal, negative line feed is as the same.
Beneficial effect of the present invention: the present invention is through respectively being provided with a sealing system in the handling appliance rear and front end; Utilize corrosion-resistant belt to carry out rolling-in or sprawl with advancing of handling appliance; Reached the purpose of sealing handling passage, prevented that effectively waste gas from escaping, significant sealing affection.

Embodiment
Below in conjunction with accompanying drawing and embodiment material handling channel seal technology of the present invention is described further:
A kind of material handling channel seal structure; Comprise handling passage 001, handling appliance 002; Described handling appliance 002 is installed on the handling passage 001; Leave one tunnel opening 011 that is used for to held suspension line cable in the middle of the handling passage 001; Handling appliance 002 rear and front end respectively is provided with a sealing system 003, and described sealing system 003 is made up of takers-in 031, pressure roller 032, corrosion-resistant belt 033, and described takers-in 031, pressure roller 032 are arranged at handling appliance 002 end, corresponding described handling passage 001 middle opening 011 one on the other; Corrosion-resistant belt 033 1 ends are fixed on the takers-in 031, and the other end is fixed in handling passage 001 1 ends after walking around pressure roller 032.
Like Fig. 1, shown in 2: described sealing system 003 comprises that two cover takers-ins 031, two overlap pressure rollers 032, the corrosion-resistant belt 033 of two covers, at the handling appliance 002 forward and backward cover that respectively is provided with.One cover takers-in 031 is fixed on handling appliance 002 upper front end, and pressure roller 032 is fixed on handling appliance 002 front end bottom, and pressure roller 032 lower roll surface and handling passage 001 upper surface distance are greater than the thickness of corrosion-resistant belt 033.At first corrosion-resistant belt 033 1 ends are fixed on the takers-in 031, when the length of corrosion-resistant belt 033 will guarantee the big ultimate range of handling appliance 002 walking, on takers-in 031, also remain with the corrosion-resistant belt 033 of three circles at least.After corrosion-resistant belt 033 was walked around pressure roller 032, the fixed position of the other end was greater than handling appliance 002 maximum distance apart of on handling passage 001, walking.Takers-in 031 is an active roll, can clockwise and anticlockwise, and make corrosion-resistant belt 033 be in tensioning state all the time.The sense of rotation of forward and backward takers-in 031 is identical all the time; And it is opposite with the direction of travel of handling appliance 002; When handling appliance 002 walking; The anterior takers-in 031 of direction of travel is constantly batching corrosion-resistant belt 033, and the takers-in 031 at the direction of travel rear portion of handling appliance 002 is constantly being sprawled corrosion-resistant belt 033.Corrosion-resistant belt 033 is no matter be to roll up or sprawl, and the speed of travel of linear velocity and handling appliance 002 is synchronous.
