Abstract
The utility model relates to a desulphurization ball grinder, in particular to a feeding device with tight seal of desulphurization ball grinder. This feeder of the utility model, desulphurization ball grinder, is composed of a tilting feeder pipe, a rotary feed pipe at the outside of the low end of the feed pipe. The utility model is characterized in that a half-open structure with indentation is placed at the low end of the feed pipe; the inner wall of the feed pipe is arranged with a water split case in parallel in the terminal, and the terminal is spiral shape. The split case is a cylinder shaped cavity encircled with feed pipe. This effect of the utility model is tight without leakage, simple and compact, low cost for wide use range.
Description
(1) technical field under
The utility model relates to the desulfurization ball mill, particularly a kind of not desulfurization ball mill feed arrangement of spillage that seals tightly.
(2) background technology
At present, the power plant of China mainly is a thermal power plant, and thermal power generation must be with burning coal as the energy, a large amount of SO that produce during coal burning
2Can cause environmental pollution, health and vegeto-animal existence are constituted a threat to.Therefore, the SO of thermal power plant
2Control emission become the task of top priority.Wet flue gas desulfurization just is used widely as the effective ways of administering the thermal power generation smoke emissioning pollution.There is feeder spillage problem in the desulfurization ball mill at present as the capital equipment of flue gas desulfurization absorbent preparation, is difficult to solve always, has increased production cost to a certain extent.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, and a kind of tight not spillage, desulfurization ball mill feed arrangement simple and compact for structure of sealing is provided.
The utility model is achieved by the following technical solution:
Desulfurization ball mill feed arrangement of the present utility model comprises the charging elephant trunk of inclination, the outside that is socketed in charging elephant trunk lower end and the feed pipe that can rotate, and its special character is: the lower end of charging elephant trunk is the semi-open type structure that has breach; The inwall of feed pipe, its end have two branch water boxes side by side, and the end is spirality inwards, and described minute water box is the cylindrical cavity around the charging elephant trunk.
Desulfurization ball mill feed arrangement of the present utility model for sealing effectiveness reaches best, is fixed with securing member and seal between feed pipe and the charging elephant trunk, and described securing member and seal are respectively trim ring and rubber ring, asbestos packing.
The beneficial effects of the utility model are, sealing is not spillage, simple structure compactness tightly, and cost is low, is easy to promote the use of.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Fig. 1 is the charging elephant trunk, and Fig. 2 is a feed pipe, and Fig. 3 is a feed arrangement.
Among the figure, 1 charging elephant trunk, 2 trim rings, 3 rubber rings and asbestos packing, 4 feed pipes, 5 charging end caps, 6 fens water boxes.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Desulfurization ball mill feed arrangement of the present utility model comprises the charging elephant trunk 1 of inclination, the outside that is socketed in charging elephant trunk lower end and the feed pipe 4 that can rotate, and the lower end of charging elephant trunk 1 is the semi-open type structure that has breach; The inwall of feed pipe 4, its end have two branch water boxes 6 side by side, and the end is spirality inwards, and described minute water box is the cylindrical cavity around the charging elephant trunk.For sealing effectiveness reaches best, be fixed with securing member and seal between feed pipe 4 and the charging elephant trunk 1, described securing member and seal are respectively trim ring 2 and rubber ring, asbestos packing.
This method is a kind of stifled method of dredging combination.As shown in Figure 1 and Figure 2, charging elephant trunk 4 ends of desulfurization ball mill feed arrangement are designed to open architecture, feed pipe 1 adopts defeated material helix tube to add the structure that two branch water boxes link to each other, and utilizes the trim ring 2 that is installed on the feed pipe 1 that rubber ring and 3 of asbestos disks are fastened on the charging elephant trunk 1.When equipment was installed, the lower end of charging elephant trunk 1 was installed in the feed pipe 4, and feed pipe 4 is fixed on the charging end cap 5.During operate as normal, along with the rotation of ball mill, defeated material helix tube is accelerated material convey materials in mill, divides water box 6 to utilize the waterwheel principle, and the slurries that return are mentioned, and falls into the open-ended place of charging elephant trunk, gets back in the ball mill, has reduced the impact of slurries; Rubber ring and asbestos packing 3 hard-pressed bales live in to expect elephant trunk 1, stop slurries excessive, seal, as Fig. 3.
Claims (2)
1. desulfurization ball mill feed arrangement, comprise inclination charging elephant trunk (1), be socketed in the outside of charging elephant trunk lower end and the feed pipe (4) that can rotate, it is characterized in that: the lower end of charging elephant trunk (1) is the semi-open type structure that has breach; The inwall of feed pipe (4), its end have two branch water boxes (6) side by side, and the end is spirality inwards, and described minute water box is the cylindrical cavity around the charging elephant trunk.
2. desulfurization ball mill feed arrangement according to claim 1 is characterized in that: be fixed with securing member and seal between feed pipe (4) and the charging elephant trunk (1), described securing member and seal are respectively trim ring (2) and rubber ring, asbestos packing.
