Abstract
The invention discloses a conveying hopper. The conveying hopper comprises a chute with the diameter reduced from top to bottom, an upper connecting piece communicating with an opening in the top of the chute as well as a lower connecting piece communicating with an opening in the bottom of the chute; air holes for introducing air into the chute are formed in the position where the chute and the upper connecting piece are connected; and the conveying hopper further comprises a stop ring for controlling the air to flow downwards along the inner wall of the chute. Pulverized coal is attached to the inner side wall of the chute, the air is controlled to pass through the air holes to be injected into the chute, the stop ring limits an air flow to flow downwards along the inner side wall of the chute, and the pulverized coal attached to the inner side wall of the chute is blown down. With the structural design, the pulverized coal attached to the inner side wall of the chute is blown down timely, the condition that a conveying pipeline is blocked finally due to large particle accumulation caused by small particle attachment is avoided, and the probability of the coal accumulation phenomenon is greatly reduced.
Description
Technical field
A kind of the present invention relates to material transportation technical field, more particularly, it relates to conveyor hopper.
Background technology
No matter the colliery obtaining on mining site and other places is by experiment and detects that being also by initial processing is required for by conveying
System is conveyed, and generally comprises the conveyor hopper being easy to that colliery is transported from eminence toward lower in induction system.
Gathering and processing integration assembly line work is the trend of coal property test industry development.Generally, gathering and processing
Streamline has the participation work of multiple stage (covering) equipment.Under normal circumstances, coal dust is when conveyor hopper, due to coal dust lighter in weight,
Easily attachment is deposited on the inclined-plane of conveyor hopper, causes long-pending coal phenomenon.Long-pending coal phenomenon can further result in coal dust and block transport
Passage, and then lead to cross-contamination, the normal work of impact induction system.
In order to prevent long-pending coal phenomenon, typically take the mode installing vibrator at present, but chute in full-automatic sample-preparing system
A lot, installing vibrator additional leads to noise very big, easily weld seam is shaken simultaneously and splits.
In sum, how to efficiently solve the problem that long-pending coal phenomenon is easily occurred on conveyor hopper, be current this area skill
Art personnel's urgent problem.
Content of the invention
In view of this, it is an object of the invention to provide a kind of conveyor hopper, the structure design of this conveyor hopper can have
Effect ground solves the problems, such as easily to occur long-pending coal phenomenon on conveyor hopper.
In order to achieve the above object, the present invention provides following technical scheme：
A kind of conveyor hopper, the upper connection connect including caliber elephant trunk tapered from top to bottom and with the open top of elephant trunk
The lower connector that part is connected with the bottom opening of elephant trunk, the junction of elephant trunk and upper connector is provided with for logical to the inside of elephant trunk
Enter the pore of gas, also include for controlling gas along the back-up ring of the inwall circulation downwards of elephant trunk.
Preferably, in above-mentioned conveyor hopper, the junction of elephant trunk and upper connector is provided with multiple pores, and pore is along elephant trunk
Side wall is uniformly distributed.
Preferably, in above-mentioned conveyor hopper, upper connector be specially and elephant trunk the first flange that matches of top profile,

Preferably, in above-mentioned conveyor hopper, first flange and second flange all connect with elephant trunk sealing welding.
Preferably, in above-mentioned conveyor hopper, first flange is provided with and is used for the bolt connecting hole of early-stage work machine connection, the
Two flanges are provided with the bolt connecting hole for connecting with downstream working machine.
Preferably, in above-mentioned conveyor hopper, at pore, be all welded with the valve connecting with pore, valve all by trachea and
Outside air injection equipment connects.
Preferably, in above-mentioned conveyor hopper, elephant trunk is specially inverted cone elephant trunk, and back-up ring is specially and inverted cone elephant trunk
The cooperation of medial wall gap inverted cone back-up ring, the top of inverted cone back-up ring and first flange are welded to connect.
The conveyor hopper that the present invention provides, connects including caliber elephant trunk tapered from top to bottom with the open top of elephant trunk
The lower connector that connects with the bottom opening of elephant trunk of upper connector, the junction of elephant trunk and upper connector is provided with for slipping
It is passed through the pore of gas inside pipe, also include for controlling gas along the back-up ring of the inwall circulation downwards of elephant trunk.
During the conveyor hopper that the application present invention provides, at coal dust moves to elephant trunk through upper connector from early-stage work machine,
Most of coal dust moves to downstream working machine through lower connector, and part coal dust is attached on the medial wall of elephant trunk, controls gas
Spray into inside elephant trunk through pore, and air-flow is limited to the downwardly direction along elephant trunk medial wall by back-up ring, will be attached to elephant trunk
The coal dust of medial wall blows off.Using said structure design, the coal dust that timely will be attached on elephant trunk medial wall blows off, it is to avoid
Little particle attachment in turn results in bulky grain and piles up the situation finally making conveyance conduit blocking so that amassing the probability that coal phenomenon occurs
Substantially reduce.This conveyor hopper has perfect circuit design simultaneously, and the pipeline of material conveying and gas injection will not the row of generation
Impact on cloth position, simultaneous gas injection blow off coal dust effect very good.
Meanwhile, the conveyor hopper that the present invention provides avoids the structure design adding vibrator, it is to avoid induction system
Weld seam is shaken and is split, and also greatly optimizes the effect that coal dust drops simultaneously.
