Abstract
A mill and slag discharge device, which comprises a slag discharge outlet, a frame body, a slag discharge chamber, a millstone holder and an air inlet, is characterized in that the slag discharge outlet is arranged on the outer part of the frame body; the slag discharge outlet is communicated with the slag discharge chamber; the slag discharge chamber is fixed in the frame body; the lower part of the slag discharge chamber is fully sealed; the upper part of the slag discharge chamber and the upper part of the concentrically arranged millstone holder form a matching clearance and can have relative rotation; In working state, the lower section of the slag discharge chamber is connected with the air inlet and is in total seal state, the upper part of it is connected with the milling chamber of the mill and the air inlet is fixed at the outer section of the frame body which connect directly with the slag discharge chamber. The bottom plate of the slag discharge chamber inclines to an angle of repose which is greater than or equal to slag. The slag discharge chamber can store slag on a period basis and the slag can be taken away on a period basis. In the utility model, scraper is omitted, completely closed slag discharge chamber is adopted, storage space of the slag discharge chamber is increased, the bottom plate structure of the slag discharge chamber is used to discharge slag automatically, which can not only save large amount of investment and reduce costs, but also make it an extremely reliable mill and slag discharge device.
Description
(1) technical field
The utility model relates to a kind of grinding machine, especially relates to the slag-draining device in the grinding machine.
(2) background technology
Miller residue discharging device is the important component part of grinding machine, and its effect is that the waste residue that milling chamber internal cause wind can't be held is caught, discharged, and also can be used as the inlet air that enters grinding machine milling chamber simultaneously and distributes passage.At present, common grinding machine discharge device is to adopt and abrasive disk seat one and the synchronous scraper that rotates, and waste residue is scraped to slag-drip opening, enters in the dreg discharging box then.Scraper is installed in the sidewall of the abrasive disk seat that is used to support mill.Because the action request of scraper, can't be need one by the required gap of rotation that forms between dreg discharging box bottom and the abrasive disk seat that rotates with avoiding, thereby also just must bring the problem of two aspects, one of its problem is that scraper just rotates naturally as long as grinding machine rotates, and makes the serious wear of scraper, lost efficacy easily, and the replacing difficulty after losing efficacy, deslagging chamber are blocked full, cause accident easily; Two of its problem is because the existence of above-mentioned rotary gap causes dust, granule waste residue to discharge grinding machine from above-mentioned gap easily, pollutes, and also causes the gap to be strengthened gradually easily, forms vicious circle.The method of head it off all concentrates on shape, the material that changes scraper now, improve in the measures such as sealing means, though these methods can improve the life-span of scraper to a certain extent, improved the sealing effectiveness of dreg discharging box, but but can't change the serious problem of blade wears, the leakage ash phenomenon that also can't avoid occurring has increased installation difficulty and equipment investment simultaneously.
(3) summary of the invention
In order to solve the technical problem that above-mentioned prior art exists, the utility model provides a kind of no scraper type miller residue discharging device, and this device can realize that not only dreg discharging box seals fully, and has the function of interim storage waste residue and interim deslagging.
The technical scheme that adopts is:
Miller residue discharging device, comprise slag-drip opening, support body, dreg discharging box, abrasive disk seat, air inlet, it is characterized in that described slag-drip opening is arranged in the support body outside, slag-drip opening is communicated with dreg discharging box, dreg discharging box is fixed in the support body, the dreg discharging box lower end seals fully, the dreg discharging box upper end forms fit clearance with the abrasive disk seat upper end of arranged concentric, and can relatively rotate, in the dreg discharging box work lower end except that be in complete sealing state air inlet is connected, the upper end directly links to each other with grinding machine milling chamber, and air inlet is fixed in the outside of support body, directly is connected with dreg discharging box.The dreg discharging box base plate tilts to be the angle of repose more than or equal to waste residue, and dreg discharging box can interimly be stored waste residue, and waste residue can interim taking away from slag-drip opening.
Operation principle: wind enters dreg discharging box by air inlet, and through entering the work of milling chamber after the uniform distribution, in the work, because the waste residue that wind can't be held can fall into dreg discharging box, waste residue slips to slag-drip opening by deadweight along the slag case base plate in the milling chamber.
The utility model has solved the problem of blade wears, also solved simultaneously gap between dreg discharging box and the abrasive disk seat because of wearing and tearing and made the problem of sealing actual effect, the utility model cancelled scraper, adopt that dreg discharging box is totally-enclosed, the memory space that increases dreg discharging box, utilize the dreg discharging box base arrangement to carry out automatic discharge, not only can save great amount of investment, reduce cost, and be extremely reliable miller residue discharging device.
(4) description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
(5) specific embodiment
Please refer to figure one, miller residue discharging device of the present utility model, comprise slag-drip opening 1, support body 2, dreg discharging box 3, abrasive disk seat 4, nozzle ring 5, packing seal 6, pressing plate 7, milling chamber 8, mill 9, air inlet 10, slag-drip opening 1 is located at support body 2 outsides, slag-drip opening 1 is communicated with dreg discharging box 3, dreg discharging box 3 is fixed in the support body 2, dreg discharging box 3 lower ends seal fully, nozzle ring 5 is established in exit, dreg discharging box 3 upper end, nozzle ring 5 is fixed on the inboard of support body 2, and there is pressing plate 7 upper end of nozzle ring 5, and abrasive disk seat 4 upper ends of dreg discharging box 3 upper ends and arranged concentric form fit clearance, and can relatively rotate, gap location is established packing seal 6, abrasive disk seat 4 upper fixed mills 9, and mill 9 tops and support body 2 form milling chamber 8, air inlet 10 is fixed in the outside of support body 2, directly is connected with dreg discharging box 3.Wind enters dreg discharging box 3 by air inlet 10, after process nozzle ring 5 evenly blows out, 8 work in the milling chamber, in the work, the waste residue that can't hold owing to wind in the milling chamber 8 can fall into dreg discharging box 3, waste residue slips to slag-drip opening 1 by deadweight along dreg discharging box 3 base plates and stores, and regularly takes waste residue away from slag-drip opening 1.Its characteristics are dreg discharging box 3 cancellation scrapers, and dreg discharging box 3 lower ends seal fully, waste residue enters dreg discharging box 3 backs and slips to slag-drip opening 1 by deadweight, the base plate of dreg discharging box 3 is in tilted layout, its inclination angle is the angle of repose more than or equal to waste residue, dreg discharging box 3 can interimly be stored waste residue, and waste residue can interim taking away from slag-drip opening 1.
