Abstract
The utility model discloses a constant volume baiting device which comprises a tube and a cylinder. A piston is arranged on a cylinder push rod and is provided with a sealing flute, and the tube is provided with a material inlet opening. An inner sleeve is arranged in the lower part of the material inlet opening of the cylinder, and the upper end of the inner sleeve is provided with a section of boss ring which can be inserted into the sealing flute. The bottom end opening of the tube is provided with a barrier awl, the barrier awl is arranged on a straight rod, and the straight rod is arranged under the piston and is connected to the push rod. Owing to the sealing form of the utility model being the inner sleeve inserting piston sealing groove form, sealing effect is very good, and the utility model has the advantages of no material leakage and high charging precision.
Description
The utility model relates to the constant-volume blanking device that is used for the constant volume blanking in a kind of factory, particularly a kind of electrolytic aluminium plant that is applicable to when producing electrolytic aluminium, reinforced constant-volume blanking device in electrolytic bath.
At present, constant-volume blanking device of the prior art, the general piston that all adopts conventional structure, the constant-volume blanking device of this employing conventional structure piston, its major defect is relatively poor, the easy leakage material of sealing effectiveness and makes epicoele returning charge of constant-volume blanking device cylindrical shell and material stock easily, so its result of use is not ideal, and in use, also need often cylindrical shell to be returned air blowing, use very inconvenient.
The purpose of this utility model is: a kind of good seal performance is provided, does not leak material, the higher constant-volume blanking device of charging precision.
The utility model is to constitute like this: it comprises cylindrical shell (1) and cylinder (2), the push rod (3) of cylinder (2) is inserted in the cylindrical shell (1), piston (4) is housed on push rod (3), and on piston (4), be provided with a circle sealed groove a, on cylindrical shell (1), be provided with inlet point b, interior cover (5) is equipped with in the below of inlet point b in cylindrical shell (1), and be provided with one section boss circle c that can inject among the sealed groove a in the upper end of interior cover (5), bottom nozzle at cylindrical shell (1) is provided with retaining awl (6), and retaining awl (6) is contained on the straight-bar (7), and straight-bar (7) is located at the below of piston (4) and is connected on the push rod (3).
Owing to adopted technique scheme, the utility model is compared with existing unloader, the advantage that the utlity model has good seal performance, do not leak material, charging precision is high.When using the utility model, the utility model vertically is installed in the hopper, makes inlet point b be positioned at the hopper bottom, when inlet point b opens, material flows in the constant volume chamber of cylindrical shell (1) bottom by deadweight, when reinforced, cylinder (2) is action downwards, promotes piston (4) and moves downward, the boss circle c of interior cover (5) is injected among its sealed groove a, thereby b closes with inlet point, by straight-bar (7) bottom retaining awl (6) is pushed open simultaneously, has so promptly realized reinforced process.Because seal form of the present utility model is the seal groove form that interior cover embeds piston, makes sealing effectiveness fine, thereby guaranteed not leak material, the not returning charge of cylindrical shell epicoele, material stock not, thereby also do not returned air blowing, improved work efficiency greatly with regard to not using.
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment of the present utility model: it comprises that cylindrical shell (1) and cylinder (2) all can adopt structure of the prior art, and the push rod (3) of cylinder (2) is inserted in the cylindrical shell (1), on push rod (3), load onto piston (4), when making piston (4), on piston (4), produce a circle sealed groove a, on cylindrical shell (1), open two inlet point b then, cover (5) in one is adorned in the below of inlet point b in cylindrical shell (1), and produce one section boss circle c that can inject among the sealed groove a in the upper end of interior cover (5), establish a retaining awl (6) at the bottom nozzle of cylindrical shell (1), and will keep off awl (6) and be contained on the straight-bar (7), and straight-bar (7) will be contained in the below of piston (4) and be connected push rod (3) and go up.
Claims (1)
1, a kind of constant-volume blanking device, it comprises cylindrical shell (1) and cylinder (2), the push rod (3) of cylinder (2) is inserted in the cylindrical shell (1), it is characterized in that: piston (4) is housed on push rod (3), and on piston (4), be provided with a circle sealed groove a, on cylindrical shell (1), be provided with inlet point b, interior cover (5) is equipped with in the below of inlet point b in cylindrical shell (1), and be provided with one section boss circle c that can inject among the sealed groove a in the upper end of interior cover (5), bottom nozzle at cylindrical shell (1) is provided with retaining awl (6), and retaining awl (6) is contained on the straight-bar (7), and straight-bar (7) is located at the below of piston (4) and is connected on the push rod (3).
