As shown in fig. 1, 2 and 3, a sealing and isolating baffle device comprises a barrel body 1, a supporting plate 2, a baffle 3, a connecting seat, a rocker arm 4 and a rotating shaft 5, wherein the barrel body 1 is of a hollow cylindrical structure with an upper end and a lower end open, the supporting plate 2 is annular, the supporting plate 2 is horizontally arranged on the inner surface of the barrel body 1, the central axis of the supporting plate 2 is superposed with the central axis of the barrel body 1, the baffle 3 is circular, the baffle 3 is positioned on the upper surface of the supporting plate 2, the central axis of the baffle 3 is superposed with the central axis of the supporting plate 2, the connecting seat is arranged on the upper surface of the baffle 3 and comprises two connecting ear plates 7 which are arranged in parallel from left to right, the two connecting ear plates 7 are connected through a pin shaft 9, the rear end of the rocker arm 4 is pivoted on the pin shaft 9, a spring 10 is connected between the, the rotating shaft 5 is fixedly connected with the rocker arm 4, and the center line of the mounting hole is positioned on the front side of the central axis of the pin shaft 9; the rotary shaft 5 for driving the rocker arm 4 to rotate is arranged in the barrel 1, two ends of the rotary shaft 5 are respectively pivoted on the barrel 1, two ends of the rotary shaft 5 are arranged on the barrel 1 in a bilateral symmetry mode, and the center of the rotary shaft 5 is not located on the central axis of the barrel 1.
In order to facilitate the installation of the spring 10, the side surface of the front end of the rocker arm 4 is an arc surface with a forward arc opening, the upper end of the spring 10 is connected to the upper side of the arc surface, the lower end of the spring 10 is connected to the upper surface of the baffle plate 3, and the spring 10 can be avoided by arranging the arc surface, so that the installation of the spring 10 is simpler and more convenient; preferably, connecting plates are provided on both the lower side of the front end of the rocker arm 4 and the upper surface of the shutter 3, and the upper and lower ends of the spring 10 are connected to the corresponding connecting plates.
The working principle of the invention is as follows: in an initial state, the baffle is positioned on the upper surface of the supporting plate, the spaces on the upper side and the lower side of the supporting plate in the cylinder are not communicated, and at the moment, the spring is in a stretching state; when the baffle needs to be opened, the rotating shaft rotates, the rotating shaft drives the rocker arm to rotate, the rocker arm drives the connecting seat and the baffle to rotate through the pin shaft, and the stretched spring can gradually contract, so that the front end of the baffle can gradually rotate upwards, the sealing ring is firstly separated, the rocker arm continues to rotate, after the rocker arm is contacted with the baffle, the rear end of the baffle begins to separate from the sealing ring, the rocker arm continues to rotate, and the baffle is gradually and completely opened around the rotating shaft;
if baffle 3 need close, pivot 5 rotates to the opposite direction, and rocking arm 4 drives baffle 3 and rotates, and the rear end of baffle 3 contacts with sealing washer 8 earlier, and rocking arm 4 continues to rotate, and baffle and rocking arm begin to break away from, and along with the rotation of rocking arm, the right-hand member of baffle compresses tightly the sealing washer downwards gradually to accomplish the closed condition.
In the present invention, the diameter of the baffle plate is larger than the inner diameter of the support plate, and the diameter of the baffle plate and the inner diameter of the support plate need to be arranged according to actual use conditions.
In order to prevent the lower ends of the rocker arms from deflecting in the process of pressing the baffle plates downwards, the invention is preferably characterized in that the number of the rocker arms is two, the two rocker arms are arranged on the baffle plates in a bilateral symmetry manner, the two connecting lug plates are positioned between the two rocker arms, and the left ends of the two rocker arms are respectively and correspondingly pivoted on the pin shafts.
In order to further improve the sealing effect of the present invention, an annular sealing ring is disposed between the baffle plate and the support plate, and the sealing ring is preferably made of rubber.
Preferably, the lower surface of the rocker arm and the upper surface of the rocker arm are parallel inclined planes, and when the rocker arm rotates to the state that the lower end of the rocker arm is in contact with the baffle, the upper surface and the lower surface of the rocker arm are both in a horizontal state.
In order to realize the stable contact of the rocker arm and the baffle, the boss is arranged on the lower surface of the rocker arm and is of an integrated structure, the lower surface of the boss is an inclined plane with the upper surface and the lower surface of the rocker arm at the same inclination angle, so that when the baffle is in the first stage, the lower surface of the boss is attached to the upper surface of the baffle, and the boss is in surface contact with the baffle.
