Abstract
An air-shutting discharging device capable of adjusting a gap comprises a casing with a cylindrical cavity. A rotating impeller is arranged in the casing, two ends of a transmission shaft of the rotating impeller are arranged in central holes of end covers on two sides of the casing through a bearing respectively, the upper portion and the bottom of the casing are provided with a feeding mouth piece and a discharging mouth piece respectively, an arc-shaped plate block with radian identical with that of an upper wall of a casing inner cavity is arranged between the upper wall of the casing inner cavity and an end of the rotating impeller, a hole matched with the feeding mouth piece is arranged in the middle of the arc-shaped plate block, a circular T-shaped groove hole is arranged on a plate body on two sides of the hole, a T-shaped end of a screw is movably connected with the inside of the circular T-shaped groove hole in matching mode, and an upper end of the screw penetrates out of the casing upwards to be threaded with a threaded hole on a casing body. The air-shutting discharging device is simple in structure, simple and fast to operate, large in adjusting range and reliable in working and effectively achieves the purposes of prolonging service life, improving production efficiency and saving cost.
Description
Technical field
The present invention relates to a kind of device for discharging for pneumatic conveying loose unpacked material device.
Background technology
Close the wind discharger generally by impeller, the housing and the end cap thereof that are provided with inlet point and discharging opening form, do not leak out when guaranteeing discharging, its requirement on machining accuracy is very high, require housing man-hour adding, the axial line three line unifications of impeller and end cap thereof, and set the gap between impeller and housing according to the size of discharging product particle, therefore, a kind of pass wind discharger of typing can only be applicable to the discharging product of fixing certain granules diameter range, and when the damage in impeller that closes the wind discharger and and the gap between housing while surpassing set index, discharging will be leaked out in a large number and can't be worked on, or gap can not be turned round impeller by feed blocking, now this pass wind discharger can only be scrapped and more renew machine.In order to overcome the existing above-mentioned shortcoming that the wind discharger exists of closing, application number is CN 200520032991.8, patent a kind of " air sealer that gap is adjustable " proposed, it comprises housing, impeller (rotor) and end cap, housing is provided with inlet point, and impeller is installed on end cap by rotating shaft, and end cap is installed on housing with bolt, on end cap and housing end face relevant position is provided with dowel hole, and end cap is located by the locating dowel pin more than two.It utilizes hold-down bolt and the gap between hold-down bolt hole on end cap suitably to regulate coordinating of end cap and housing, thereby reach the adjusting along with gap between the synchronization-moving impeller of end cap and housing upper inlet inwall, effectively extend the service life of closing the wind discharger.But it is very limited that this structure is regulated the amplitude in gap, only limits to the minim gap distance between the hold-down bolt hole on hold-down bolt and end cap, and also need to fix with pin troublesome poeration after regulating.
Summary of the invention
The pass wind discharger that the purpose of this invention is to provide a kind of simple in structure, easy and simple to handle, adjustable clearance that the range of regulation scope is large.
Realize that the above-mentioned purpose technical solution is: a kind of pass wind discharger of adjustable clearance, comprise the casing with cylindrical cavity, rotary blade is installed in casing, the transmission shaft two ends of rotary blade are installed in the centre hole of casing both sides end cap by bearing respectively, charging mouth piece and discharging mouth piece are established respectively in casing top and bottom, be provided with the arc plate consistent with chassis cavity upper wall radian between described chassis cavity upper wall and rotary blade end, the middle part of described arc plate offers the hole matched with the charging mouth piece, offer round T slot hole on the plate body of hole both sides, the T shape end activity of screw rod is coupled in described round T slot hole, the upper end of screw rod upwards passes casing, and with engine housing on the screw bolt.
As preferably, be installed with the jam nut joined with the casing appearance on described screw rod.
As preferably, described rotary blade surface coating has the abrasion resistant paint layer.
The invention has the beneficial effects as follows: owing to being provided with the arc plate of movable lifting between chassis cavity upper wall and rotary blade end, substitute fixing chassis cavity upper wall as and the rotary blade end between sealing surface, thereby while when the operation abrasion of rotary blade end, increasing seal clearance, recover appropriate seal clearance by the lift adjustment arc plate and keep normal production, effectively realized extend closing wind discharger service life, enhanced productivity and cost-saving purpose.The present invention is simple in structure, easy and simple to handle, quick, and the range of regulation scope is large, reliable operation.
