Abstract
The invention provides a sealing device of a wet type ball grinder head section in a thermal plant. The sealing device comprises sealing packing, a clamping apparatus, a radial locking device and an axial compressing device, wherein the sealing packing is fixed at the joint of the grinder head section and an inlet tube; the clamping apparatus is used for fixing and compressing the outside of the sealing packing; the radial locking device is used for locking the clamping apparatus; and the axial compressing device is used for fixing the inlet tube and compressing the clamping apparatus. According to the sealing device of the wet type ball grinder head section in the thermal plant provided by the invention, the joint face of the sealing packing and the ball grinder can be adjusted regularly, and mortar leakage at the inlet of the ball grinder is effectively prevented, so that the overhaul maintenance quantity is reduced.
Description
Technical field
The present invention relates to the wet ball mill technical field, particularly the sealing device of a kind of thermal power plant wet ball-milling machine head.
Background technology
Ball mill is after material is broken, the key equipment of pulverizing again.Formed by major parts such as feed portion, discharging portion, rotating part, driving sections.Ball mill is widely used in cement, silicate product, and production industries such as New Building Materials, refractory material, chemical fertilizer, black and non-ferrous metal ore and glass ceramics carry out dry type or wet type grinding to various ores and other grindability material.
The thermal power plant is equipped with flue gas desulfur device substantially at present, and wherein the lime stone grinding machine is most important equipment in the serum producing system.Generally the lime stone scheme of grinding of Cai Yonging has dry grinding and two kinds of wet-millings, and based on wet-milling, wet mill with horizontal ball mill in the highest flight.
In the use of wet ball mill, need with water with enter grinding machine after raw material mixes and carry out wet-milling, if the ball mill entrance can not obtain excellent sealing, the lime stone slurry that grinds will spill from the grinding machine porch, not only cause the waste of working medium, and bring unnecessary pollution to production environment, influence normal use and the healthy operation of ball mill.
In order to address the above problem, general wet ball mill entrance has all been installed sealing device.As shown in Figure 1, prior art generally adopts packing 101 as airtight and watertight padding, and its gland 103 is fixed in grinding machine staving entrance 102 and seals.Its shortcoming is: airtight and watertight padding gland 103 is in operation along with the ball mill staving rotates together, can not effectively compress filler to reach excellent sealing effect; When there was deviation at the center of inlet duct 102 and grinding machine entrance, the gap was inhomogeneous all around can to cause inlet duct and grinding machine entrance, adopted this moment packing_seal to tend to generation leakage phenomenon in place's bigger than normal in the gap.Taking place frequently of ball mill entrance spillage defective have a strong impact on the stable operation of equipment, and the repair and maintenance workload is big.
Summary of the invention
The invention provides the sealing device of a kind of thermal power plant wet ball-milling machine head, can regularly adjust airtight and watertight padding and ball mill composition surface, effectively prevented ball mill entrance spillage phenomenon.
To achieve these goals, the invention provides following technical scheme:
The sealing device of a kind of thermal power plant wet ball-milling machine head, it comprises: airtight and watertight padding, jig, radially locking device, axial pressing device, wherein:
The junction of grinding machine head and inlet tube is fixed in described airtight and watertight padding;
The airtight and watertight padding outside is fixed and compressed to described jig;
Described radially locking device is locked described jig;
Described axial pressing device is fixed in inlet tube place and screw clamp.
Preferably, described radially locking device comprise tie down screw radially and with this first nut of matching of tie down screw radially, described axial pressing device comprises axial compression screw rod and second nut that matches with this axial compression screw rod.
By implementing above technical scheme, has following technique effect: the sealing device of thermal power plant provided by the invention wet ball-milling machine head, jig and the inlet duct of this wet ball-milling machine head sealing device fix, can regularly adjust airtight and watertight padding and ball mill composition surface, effectively prevented ball mill entrance spillage phenomenon, the repair and maintenance amount is reduced, improve working medium waste and environmental pollution problems.Can use on the wet ball mill of all size.

The invention provides the sealing device of a kind of thermal power plant wet ball-milling machine head, as Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, it comprises: airtight and watertight padding 110, jig 120, radially locking device 130, axial pressing device 221, wherein:
Described airtight and watertight padding 110 can adopt felt to replace traditional packing, is fixed in grinding machine head and inlet tube 210 junctions.
Described jig 120 is used for fixing and compresses airtight and watertight padding 110, and described jig 120 can be inserted in its inside with airtight and watertight padding 110 during use.
Described radially locking device cooperates jig 120 to use, and by penetrating in first bolt hole 121 of jig 120 and second bolt hole 122, is used for locking jig 120.
Described axial pressing device 221 is fixed in the inlet tube place, is used for screw clamp to reach sealing effectiveness.
In above-described embodiment, preferably, described radially locking device comprise tie down screw radially and with this first nut of matching of tie down screw radially, described axial pressing device comprises axial compression screw rod and second nut that matches with this axial compression screw rod.
More than the sealing device of a kind of thermal power plant wet ball-milling machine head that the embodiment of the invention is provided be described in detail, for one of ordinary skill in the art, thought according to the embodiment of the invention, part in specific embodiments and applications all can change, in sum, this description should not be construed as limitation of the present invention.
