The embodiment provides a serial-type material shutting valve, and the serial-type material shutting valve is particularly suitable for being applied to the blanking process of powdery materials in lithium battery raw materials in the lithium battery industry.

The series material shutting valve of this embodiment includes material shutting valves connected in series with each other, and this embodiment specifically includes two material shutting valves connected in series with each other, that is, a first material shutting valve 1 and a second material shutting valve 2. Specifically, as shown in fig. 2-3, the first material shutting valve 1 sequentially includes, from top to bottom, a first material inlet 1-1, a first valve body 1-2, a first material discharging hopper 1-3, and a first material discharging outlet 1-4; the second material closing valve 2 sequentially comprises a second feeding hole 2-1, a second valve body 2-2, a second discharging hopper 2-3 and a second discharging hole 2-4 from top to bottom. Wherein, the first blanking hopper 1-3 and the second blanking hopper 2-3 are both in a funnel shape which gradually shrinks from top to bottom. In this embodiment, the cross-section of the first valve body 1-2 and the second valve body 2-2 is preferably rectangular, and correspondingly, the cross-section of the first hopper 1-3 and the second hopper 2-3 is also rectangular. In order to facilitate monitoring of the quantitative blanking process, a window assembly 7 capable of observing the internal condition of the valve body can be arranged on the front side of the first valve body 1-2 and the second valve body 2-2.

As shown in fig. 1-3, a first discharge port 1-4 of the first material shutting valve 1 is butted with a second feed port 2-1 of the second material shutting valve 2, so that the first material shutting valve 1 and the second material shutting valve 2 are connected in series to form a series material shutting valve of the embodiment. The first material closing valve 1 is provided with a material closing mechanism capable of controlling the opening and closing of the first feed port 1-1, and the second material closing valve 2 is provided with a material closing mechanism capable of controlling the opening and closing of the second feed port 2-1. In this embodiment, the material closing mechanisms on the material closing valves have the same structure. The material closing mechanisms on the material closing valves are mutually independent to control the opening and closing of the feed inlets of the material closing valves.

As shown in fig. 2 to 4, the preferred structure of the material closing mechanism in this embodiment includes a driving device, a rocker arm 4, a material closing door rotating shaft 9, and a material closing door assembly. The driving device is mainly used for providing driving force for the rotation of the rocker arm 4, and a cylinder, a motor and the like in the prior art can be used as the driving device, but in order to improve the stability of controlling the quantitative blanking process, the cylinder 3 is preferably used as the driving device in the embodiment. In this embodiment, the cylinder body of the cylinder 3 is fixed to the side surface of the valve body through the cylinder mounting seat 8. The rocker arm 4 is a connecting rod of a crank structure, one end of the rocker arm 4 is hinged with a piston rod of the air cylinder 3, and the other end of the rocker arm 4 is fixedly connected with a rotating shaft 9 of the material closing door. Specifically, the material closing door rotating shaft 9 is perpendicular to the plane where the air cylinder 3 and the material closing door rotating shaft 9 are located, one end of the material closing door rotating shaft 9 is fixedly connected with the other end of the rocker arm 4 through the tensioning sleeve 5, and the other end of the material closing door rotating shaft 9 movably penetrates through the side wall of the valve body and extends into the valve body. Specifically, the material closing door rotating shaft 9 is rotatably connected with the side wall of the valve body through a bearing 10 and an oil seal 11, and the oil seal 11 is closer to one side of the valve body 1 relative to the bearing 10, so that the material can be prevented from entering the bearing 10 and damaging the bearing 10.

In this embodiment, the material closing door assembly is mounted on the material closing door rotating shaft 9 extending into the valve body, and the material closing door assembly can close or open the feeding hole along with the rotation of the material closing door rotating shaft 9. Preferably, the material closing door assembly comprises a material blocking plate 6 and a support rod 12, one end of the support rod 12 is fixedly connected to the rotating shaft 9 of the material closing door, and the material blocking plate 6 is installed on the support rod 12. It can be understood that, in order to achieve a better blocking effect, the size of the blocking plate 6 should be larger than that of the feeding hole, as shown in fig. 4, so that the blocking plate 6 can completely block the corresponding feeding hole in the closed state of the valve.

In order to further improve the stability of quantitative blanking control, the material closing mechanisms can be arranged on both sides of the valve body. When the above-mentioned material mechanism that closes of bilateral symmetry installation of valve body, two structures of closing the material mechanism are the same, but close bin gate pivot 9 and only need set up one (can understand that two are closed bin gate pivot 9 and dock into one), and close bin gate pivot 9's both ends and the valve body and correspond the lateral wall and pass through bearing and oil blanket rotation connection.

In the blanking process, corresponding material closing valves are regularly opened and closed according to the preset quantitative blanking requirement, and the switching of opening of a group of valves is closed through a group of valves, so that the quantitative blanking of the raw materials is realized. The opening or closing method of the material closing valve comprises the following steps: the oil cylinder on the corresponding material closing valve works, and a piston rod of the oil cylinder drives the rotating shaft of the material closing valve to rotate through the driving rocker arm, so that the material closing door assembly can be driven to open or close the feeding hole. When the piston rod of the oil cylinder moves reversely, the corresponding material closing valve can be changed from opening to closing/closing to opening.

According to the content of this embodiment, the purpose of the present invention can also be achieved by a serial material-closing valve with a plurality of material-closing valves connected in series, which is not described herein again.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
