In order to facilitate the installation of the discharge mounting seat 7, a discharge mounting seat 7 is fixed on the side of the storage tank body 1, as shown in the attached figure. Figure 4As shown, the quantitative discharge seat 8 is fixedly installed on the lower side of the discharge mounting seat 7 by bolts, the driving electric cylinder 9 is a servo electric cylinder, and the driving electric cylinder 9 is fixedly installed on the upper side of the discharge mounting seat 7 by bolts. The discharge plug 10 is slidably fitted in the cavity set inside the quantitative discharge seat 8 to form a plug-type discharge structure. The driving electric cylinder 9 is located directly above the quantitative discharge seat 8, and the discharge plug 10 is fixedly connected to the push rod end of the driving electric cylinder 9. The discharge plug 10 moves in the inner cavity of the quantitative discharge seat 8 under the drive of the driving electric cylinder 9.

Figure 5 As shown, the feed through hole 14 is arranged on the side of the quantitative discharge seat 8, and the feed through hole 14 is connected with the interior of the storage tank body 1. The first valve plug 11 and the second valve plug 12 are both made of rubber material, and the first valve plug 11 and the second valve plug 12 have the same structure. In order to facilitate the communication and transportation of the electrolyte, material connecting holes 18 are arranged on the upper parts of the first valve plug 11 and the second valve plug 12.

After reaching the set stroke, the discharge plug 10 stops, and then the discharge plug 10 moves downward under the drive of the driving electric cylinder 9. Under the downward pressure of the discharge plug 10, the hydraulic conduction of the electrolyte pushes the spring 13, and the first valve plug 11 moves backward and resets and is tightly closed on the open side of the feed through hole 14. At the same time, the second valve plug 12 is pushed downward by the hydraulic force and separated from the open side of the discharge through hole 15, so that the electrolyte enters the discharge through hole 15 from the material connecting hole 18 of the second valve plug 12 and is discharged to the outside, completing the quantitative discharge of the electrolyte.

[0032] In summary, the storage device adopts a plug-type quantitative feeding structure, and a quantitative discharge seat 8 and a driving electric cylinder 9 are arranged on the discharge side of the storage tank body 1. The driving electric cylinder 9 is used to drive the discharge plug 10 in the quantitative discharge seat 8, and the liquid pulling pressure is used in conjunction with the first valve plug 11 and the second valve plug 12 to realize the connection switching control of the through holes on both sides. The first valve plug 11 and the second valve plug 12 are alternately connected to realize the suction and discharge operations of the electrolyte in the quantitative discharge seat 8, and the precise control of the electrolyte discharge amount can be achieved by controlling the displacement of the discharge plug 10. The structure is simple and the operation is reliable, and the electrolyte can be accurately and quickly quantitatively taken.
