Abstract
The utility model provides a sealing device of a heat-engine plant wet-type ball grinding mill head. The sealing device comprises sealing padding, a clamping tool, a radial locking device and axial pressing devices, wherein the sealing padding is fixed at the connecting position of the ball grinding mill head and an inlet pipe, the outer face of the sealing padding is fixed and tightly pressed by the clamping tool, the clamping tool is locked through the radial locking device, and the axial pressing devices are fixed at the position of the inlet pipe and tightly press the clamping tool. According to the sealing device of the heat-engine plant wet-type ball grinding mill head, the jointed face of the sealing padding and a ball grinding mill can be adjusted at the fixed period, the slurry leakage phenomenon in an inlet of the ball grinding mill is effectively prevented, and overhauling and maintenance loads are reduced.
Description
Technical field
The utility model relates to the wet ball mill technical field, particularly the seal arrangement of a kind of thermal power plant wet ball-milling machine head.
Background technique
Pebble mill is after material is broken, the key equipment of pulverizing again.Formed by major components such as feed section, discharging portion, rotating part, transmission units.Pebble mill is widely used in cement, silicate product, and the production industries such as New Building Materials, refractory material, chemical fertilizer, black and non-ferrous metal ore and glass ceramic 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 limestone grinding machine is most important equipment in the serum producing system.The limestone that generally adopts grinds scheme two kinds of dry grinding and wet-millings, and take wet-milling as main, wet mill with horizontal ball mill in the highest flight.
In the use of wet ball mill, need to water with enter grinding machine after raw material mixes and carry out wet-milling, if the pebble mill entrance can not obtain excellent sealing, the lime stone slurry that grinds will spill from the grinding machine ingress, not only cause the waste of working medium, and bring unnecessary pollution to production environment, affect normal use and the healthy operation of pebble mill.
In order to address the above problem, general wet ball mill inlet has all been installed seal arrangement.As shown in Figure 1, prior art generally adopts packing 101 as stuffing box packing, and its Gland 103 is fixed in grinding machine staving entrance 102 and seals.Its shortcoming is: stuffing box packing gland 103 is in operation along with the pebble mill staving rotates together, can not effectively compress filler to reach excellent sealing effect; When there was deviation at the center of inlet pipe 102 and grinding machine entrance, the gap was inhomogeneous all around can to cause inlet pipe 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 pebble mill entrance spillage defective have a strong impact on the stable operation of equipment, and the repair and maintenance workload is large.
The model utility content
The utility model provides the seal arrangement of a kind of thermal power plant wet ball-milling machine head, can regularly adjust stuffing box packing and pebble mill mating face, has effectively prevented pebble mill entrance spillage phenomenon.
To achieve these goals, the utility model provides following technological scheme:
The seal arrangement of a kind of thermal power plant wet ball-milling machine head, it comprises: stuffing box packing, jig, radially locking device, axial pressing device, wherein:
The joint of grinder head and inlet duct is fixed in described stuffing box packing;
Described jig is fixed and press seal filler outside;
Described radially locking device is locked described jig;
Described axial pressing device is fixed in inlet duct place and screw clamp.
Preferably, described radially locking device comprise locking screw radially and with this first nut of matching of locking screw radially, described axial pressing device comprises axial compression screw rod and the second nut that matches with this axial compression screw rod.
By implementing above technological scheme, has following technique effect: the seal arrangement of thermal power plant's wet ball-milling machine head that the utility model provides, jig and the inlet pipe of this wet ball-milling machine head seal arrangement fix, can regularly adjust stuffing box packing and pebble mill mating face, effectively prevented pebble mill entrance spillage phenomenon, the repair and maintenance amount is reduced, improve the problem of working medium waste and environmental pollution.Can use on the wet ball mill of all size.
