Detailed description of the invention
Below in conjunction with the accompanying drawings and the present invention is specifically described by embodiment.
Fig. 1 show the structural representation front view of the present invention.
Fig. 2 show the structural representation left view of the present invention.
The present invention include feed hopper 1, upper sealing valve 2, middle sealing valve 3, hold ball device 4, falling sphere pipe 5 and seal air interface 6,
Lower sealing valve 7, connecting tube 8.
Described bucket of scoring 1 has upper sealing valve 2 with holding to be connected between ball device 4, holds in being connected between ball device 4 with falling sphere pipe 5 and having
Seal valve 3 and lower sealing valve 7, described middle sealing valve 3 and lower sealing valve 7 to be connected by connecting tube 8.
Described upper sealing valve 2 is pneumatic operated valve, seals whole ball adding device before and after for ball adding；
Described middle sealing valve 3 is electrodynamic valve, for carrying the falling impacts of steel ball；
Described lower sealing valve 7 is pneumatic operated valve, the sealing of pipeline when ball adding.
Inside described feed hopper 1, buffer board is installed, is used for slowing down the speed that steel ball declines.
The described ball device 4 that holds, for carrying steel ball, is provided with buffer board inside it, be used for slowing down the speed that steel ball declines.
It is provided with the buffering inclined tube of 40 °-50 ° in the middle part of described falling sphere pipe 5, is provided with bottom falling sphere pipe 5 and fits with raw coal inlet
The inclined tube joined.
Described feed hopper 1 upper end is connected by expansion bolt and two layers of basis, and falling sphere pipe 5 lower end is with raw coal inlet even
Connect, enter to install and seal air interface 6 falling sphere pipe 5 and raw coal inlet are attached.
The operation principle of the present invention and work process:
1) first, connect and seal air interface 6, lead to sealing air to raw coal porch；
2) then, open upper sealing valve 2 and whole ball adding device is sealed, ready steel ball is entered through bucket 1 of scoring
Entering to hold ball device 4, middle sealing valve 3 carries the falling impacts of steel ball, but long-time use can make the deformation of middle sealing valve 3 cause sealing effect
The most undesirable, lower sealing valve 7 make up sealing valve 3 and seal bad problem；
3) after steel ball has loaded, closing upper sealing valve 2, open lower sealing valve 7, middle sealing valve 3 successively, steel ball is through falling sphere
Pipe 5 enters raw coal inlet, the incline structure of falling sphere pipe 5 effectively slow down the falling speed of steel ball, it is to avoid to coal pulverizer import
Impact；
4), after ball adding completes, seal valve 3, lower sealing valve 7 in turning off successively, simultaneously turn off sealing air.
Owing to pneumatic operated valve can not carry large impact, but pneumatic operated valve seals fast, and electrodynamic valve can carry large impact, but seals
Slowly.Therefore, first beat pneumatic operated valve-lower sealing valve 7 during unlatching to avoid lower sealing valve 7 to carry large impact；First close during closedown electrodynamic valve-
Middle sealing valve 3, it is to avoid lower sealing valve 7 is impacted by remaining steel ball.
Falling sphere pipe of the present invention is connected with raw coal inlet, it is achieved online ball adding, at bucket of scoring, holds increasing between ball device and falling sphere pipe
Add connecting tube and sealed valve, it is ensured that the long-time sealing used.The present invention has simple in construction, it is easy to adjusts and ties up
Protect, economize on resources, improve production efficiency.
The embodiment above of the present invention, is merely illustrative, and is not only, all within the scope of the present invention or equivalent this
Change in the range of invention is all surrounded by the present invention.
