Description
Technical field
The utility model is related to a kind of feeding device of hazardous waste processing technology field, more particularly to a kind of with anti-
The material-pulling device of returning charge function.
Background technology
Material-pulling device is a kind of device for being usually used in waste incineration and dangerous waste burning rotary kiln end charging, generally by outer
Shell, material pushing box and hydraulic cylinder composition, material pushing box are moved forward and backward and material are pushed into kiln repeatedly by Driven by Hydraulic Cylinder in shell
Burn.In order to ensure that material pushing box is moved flexibly in shell, it would generally be left during design between shell and material pushing box certain
Gap, but this design can make material pushing box take back a small amount of material in return.Although the material taken back every time is seldom, with
Material pushing box ceaselessly reciprocal, material is understood after material pushing box and both sides bulk deposition after extruding repeatedly, to a certain extent can be right
Equipment causes abrasion, accordingly, it would be desirable to through frequently with manual cleaning.Due to often carrying poisonous, harmful and stench in rubbish and dangerous waste
Material, manual cleaning not only increases the work load of operator, and certain infringement can be also caused to health of human body.
Utility model content
To overcome the shortcomings of the existing technology, the utility model provides a kind of material-pulling device with revert prevention function, structure
Simply, environmental protection and economy, can prevent material from returning, and reduce the abrasion to material pushing box and shell, improve the service efficiency of equipment, reduction
The labor intensity of workman.
In order to achieve the above object, the utility model is realized using following technical scheme：
A kind of material-pulling device with revert prevention function, including scraper, shell, material pushing box and drive device, it is special
Levy and be, the top and both sides at the nearly feeding mouth end of the shell are provided with scraper, and material pushing box is in the driving dress being hinged with it
It can be moved back and forth in the presence of putting along the inside of shell.
The scraper is made up of material scraping plate, housing, spring and cover plate, and wherein material scraping plate is arranged in housing, with shell
Body is slidably connected；The spring one end is connected with cover plate, the other end and material scraping plate are connected, and spring makes material scraping plate lower end always be close to
Material pushing box；The cover plate spiral-lock on housing, between be bolted.
The preferred high elasticity abrasion-proof duroplasts material of material scraping plate.
The scraper is designed as being always in the reciprocating extreme position of material pushing box, i.e. scraper always position
Between the front and back ends of material pushing box.
Compared with prior art, the beneficial effects of the utility model are：
1) it is greatly reduced from the inventory that gap is taken back between material pushing box shell, after preventing that the solid accumulation being brought back from hardening
Extra abrasion is caused to material pushing box and shell, the service efficiency of equipment is improved, maintenance cost is reduced；
2) workload of manual cleaning maintenance is substantially reduced, labor strength is reduced, and prevent having in scale removal process
Malicious harmful waste is to human body and environmental pollution；
3) it is simple in construction, environmental protection and economy.

Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in figs 1 to 6, a kind of material-pulling device with revert prevention function described in the utility model, including scraper dress
2, shell 3, material pushing box 4 and drive device 5 are put, the top and both sides at the nearly feeding mouth end of the shell 3 are provided with scraper 2,
Material pushing box 4 can be moved back and forth in the presence of the drive device 5 being hinged with it along the inside of shell 3, under gravity pusher
Case 4 has certain interval with the lower contacts of shell 3 and the top and both sides of shell 3, it is ensured that material pushing box 4 moves spirit in shell 3
It is living.
The scraper 2 is made up of material scraping plate 7, housing 6, spring 8 and cover plate 9, and wherein material scraping plate 7 is arranged on housing 6
It is interior, it is slidably connected, upper and lower can moves in the housing with housing 6；Described one end of spring 8 is connected with cover plate 9, the other end and scraper
Plate 7 is connected, and under the effect of spring 8, material pushing box 4 is always close in the lower end of material scraping plate 7, is played sealing and backgauge effect, is prevented from returning
Material；The spiral-lock of cover plate 9 on housing 6, between be bolted.
The preferred high elasticity abrasion-proof duroplasts material of material scraping plate 7.
The scraper 2 is designed as being always in the reciprocating extreme position of material pushing box 4, i.e., scraper 2 is total
It is between the front and back ends of material pushing box 4, it is ensured that material pushing box 4 is always close in the lower end of material scraping plate 7, and playing sealing prevents returning charge
Purpose.
Operation principle：
By taking the work of the top material scraping plate 7 of shell 3 as an example.
During pusher (as shown in Figure 4), the material pushing box 4 reaches and pushed away to left movement (pusher) in the presence of drive device 5
During the extreme position of material, the end of nearly drive device 5 of material pushing box 4 is located at the right of feeding mouth 1 and scraper 2, blocks feeding mouth 1
In material it is deposited in the top of material pushing box 4, the left side of material scraping plate 7, now, material scraping plate 7 is not stretched out outside material pushing box 4 yet,
I.e. material pushing box 4 is always close in the lower end of material scraping plate 7；
During return (as shown in Figure 5), i.e., it is deposited in material pushing box when material pushing box 4 is moved right in the presence of drive device 5
The partial material of 4 tops can be moved right with material pushing box 4 in the presence of frictional force, material scraping plate 7 in the presence of spring 8 all the time
It is close to the top of material pushing box 4 and wipes the material being brought back off, it is stayed at feeding mouth 1.Material pushing box 4 reaches the extreme position of return
When, the end of remote drive device 5 of material pushing box 4 is located at the left side of scraper 2, and now, material scraping plate 7 is not stretched out outside material pushing box 4 yet, i.e.,
Always it is close to material pushing box 4 in the lower end of material scraping plate 7.
The operation principle of the both sides material scraping plate 7 of shell 3 work is ibid.
Further, when material scraping plate 7 weares and teares, material scraping plate 7 can be in the presence of spring 8 along the downward fortune of 2 shell of scraper 6
It is dynamic, continue to be close to the top of material pushing box 4, it is ensured that play the purpose of scraper effect.
It is described above, only the utility model preferably embodiment, but protection domain of the present utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model is disclosed, according to this practicality
New technical scheme and its utility model design are subject to equivalent substitution or change, should all cover in protection model of the present utility model
Within enclosing.
