(2) between inlet pipe and outlet pipe, be provided with the snubber of a large space in addition.
Large-scale aluminum electrolytic cell hopper high charge level gas barrier of the present utility model laterally also can be opened a clean-up port or a purge tube is set near an end of outlet pipe at snubber.In case when snubber cavity inner product has been deposited the powder of some amount, can clear up it by this clean-up port or purge tube.Clean-up port (or pipe) has sealing of lid at ordinary times; Only just can be when needs are cleared up with covered opening.
Large-scale aluminum electrolytic cell hopper high charge level gas barrier of the present utility model, the relative position between the shape of the inlet pipe of its vapor pipe, the relative position of outlet pipe, snubber and it and the vapor pipe can be by a plurality of designs.Slightly lifting numerical example below is illustrated:
(1) to be placed in the top of hopper one side be right cylinder to snubber.The snubber below is connected with the inlet pipe of flange with hopper top vapor pipe; Top one side of snubber connects the outlet pipe of vapor pipe, and the top of outlet pipe is higher than the top of lower inlet pipe.
(2) to be placed in the top of hopper one side be right cylinder to snubber.The snubber below is connected with the inlet pipe of flange with hopper top vapor pipe; One side of flange has a small sircle hole, wherein inserts and fix the outlet pipe of a vapor pipe, and the top of outlet pipe is higher than the top of lower inlet pipe.
(3) snubber is placed in the top of hopper one side, and its front view is the combination of a rectangle and a right-angled trapezium, and snubber one end below is connected with the inlet pipe of flange with hopper top vapor pipe; The other end of snubber is promptly settled the outlet pipe of vapor pipe near one end bottom, trapezoidal top, the top of this outlet pipe is higher than the top of the inlet pipe of opposite side.
(4) snubber is placed in the top of hopper one side, its front view be a rectangle and about two right-angled trapezium combine.Below, snubber middle part is connected with the inlet pipe of flange with hopper top vapor pipe; The bottom, two ends, the left and right sides of snubber respectively is provided with the outlet pipe of a vapor pipe, and the top of two outlet pipes is higher than the top of centre inlet pipe.
Large-scale aluminum electrolytic cell hopper high charge level gas barrier of the present utility model is compared with the same device that now can see, and its structure possesses following feature:
(1) venting port is big with the material level difference between the opening for feed;
(2) distance between venting port and the opening for feed;
(3) opening at low material level place is big;
(4) flow velocity of exhaust ports air-flow is low.
The feature of comprehensive said structure, as can be seen, the utility model possesses following advantage:
(1) vapor pipe can save production cost to material is few in addition;
(2) device itself is simple in structure, reduced investment;
(3) in use, security is good, maintenance free;
(4) system's feed time weak point, save energy.
