[0032] The following is combined with Figure 1 to Figure 6 The utility model is further described in detail, but it is not intended to limit the utility model.

[0033] like Figure 1As shown, in one embodiment of the utility model, the battery slurry pushing device comprises a container 1, a pusher 2 and a buffer 3; a storage cavity 11 is provided in the container 1; a discharge port 104 connected to the storage cavity 11 is also provided on the container 1; the pusher 2 is arranged in the storage cavity 11, and the pushing direction of the pusher 2 is the same as the depth direction of the storage cavity 11; the buffer 3 is connected to the inside of the storage cavity 11, and is arranged in the pushing direction of the pusher 2. Figure 1 As shown, the pushing direction of the pushing body 2 and the depth direction of the storage cavity 11 are both from top to bottom.

[0034] The technical solution of the utility model uses a buffer body 3 to buffer and decompose the impact force caused by the downward movement of the pushing body 2, and can gradually reduce the movement speed of the pushing body 2, thereby effectively protecting the pushing body 2 itself and the inner wall of the containing body 1 from damage by the impact force, thereby increasing the service life of the pushing body 2 and ensuring the stability and safety of the movement; and can also reduce the cost of spare parts and reduce the pressure of storage inventory.

[0035] Among them, one end of the pushing body 2 away from the buffer body 3 is used to be connected to the air compressor; driven by the air compressor, the pushing body 2 is pushed out at a pressure of 0.3MPa of compressed air.

[0036] Specifically, in some embodiments, Figure 1 and 2 As shown, the container 1 includes an input pipe 101, a discharge pipe 102 and a main pipe 103; the input pipe 101 is connected to one end of the main pipe 103; the discharge pipe 102 is connected to the side end of the main pipe 103; and the discharge port 104 is arranged on the discharge pipe 102; the pushing body 2 can move from the input pipe 101 to the main pipe 103.

[0037] Specifically, in some embodiments, Figure 1 As shown, a sealing plate 12 is provided inside the main pipeline 103; the projection surface of the sealing plate 12 toward the horizontal plane is greater than or equal to the projection surface of the storage cavity 11 toward the horizontal plane; and the buffer body 3 is arranged on the sealing plate 12. This structure can realize that the container 1 has only an inlet and a side outlet through the sealing plate 12 at the bottom, thereby ensuring the smoothness of transportation.

[0038] Specifically, in some embodiments, Figure 1 and 2As shown, the buffer body 3 includes a contact buffer 31 and an extrusion buffer 32; the contact buffer 31 is in contact with and connected to the pusher 2; the extrusion buffer 32 is connected to one side end of the contact buffer 31 and is arranged opposite to the pusher 2; and the extrusion buffer 32 is connected to the inner bottom of the accommodating body 1. This structure can reduce the impact force brought by the pusher 2 in high-speed movement to a greater extent through the dual buffering effect of the contact buffer 31 and the extrusion buffer 32, thereby improving the stability and safety of the operation.

[0039] Specifically, in some embodiments, the contact buffer 31 is a silicone pad or a rubber pad; the silicone pad or the rubber pad effectively performs a preliminary buffering and decomposition effect on the impact force, thereby improving the safety of use.

[0041] Specifically, in some embodiments, Figure 2 and 3 As shown, the extrusion buffer 32 includes at least one elastic member 322 and at least two connecting plates 321; all the connecting plates 321 are arranged side by side; and the elastic member 322 is arranged between two adjacent connecting plates 321; the uppermost connecting plate 321 is connected to the contact buffer 31; and the lowermost connecting plate 321 is connected to the containing body 1 (the sealing plate 12). Figure 3 and 4 As shown, there are two connecting plates 321, which are arranged side by side; there are three elastic members 322, which are all arranged between two connecting plates 321; and an angle α is set between two adjacent elastic members 322; the angle α is 100° to 120°, preferably 120°. By forming an angle of 120° between the intermediate elastic members 322, the smoothness of the extrusion, contraction and rebound activities can be guaranteed.

[0042] The connecting plate 321 is provided with a second mounting hole 3213; the contact buffer 31 is also provided with a first mounting hole 312; and the first mounting hole 312 and the second mounting hole 3213 are connected as a whole via a fixing rod 33 (fixing rod 33 and screw).

[0043] Specifically, a reinforcing inner rod 3211 is provided in the connecting plate 321; a buffer cavity 3212 is provided between the reinforcing inner rod 3211 and the body of the connecting plate 321. The reinforcing inner rod 3211 is a herringbone reinforcing inner rod.

[0044] Specifically, in some embodiments, Figure 3 and 4 As shown, the elastic member 322 includes a spring 3222 and at least two limit blocks 3221; both side ends of the spring 3222 are respectively connected to two adjacent limit blocks 3221; and the limit blocks 3221 are connected to the connecting plate 321. Figure 4 and 5 As shown, the limiting block 3221 includes a first mounting block 32211 and a second mounting block 32212 connected to each other; and the first mounting block 32211 passes through the connecting plate 321 and is connected to the second mounting block 32212; and a limiting groove 32213 is provided between the first mounting block 32211 and the second mounting block 32212; the connecting plate 321 is arranged in the limiting groove 32213. Further, the first mounting block 32211 is a Y-shaped mounting block; and the second mounting block 32212 is a cylindrical mounting block.

[0045] Specifically, in some embodiments, Figure 1 and 6 As shown, the pusher 2 includes a connecting shaft 22 and a sphere 21 connected to at least one side end of the connecting shaft 22; the sphere 21 is disposed toward the buffer body 3. Figure 6 As shown, at least one side membrane 23 is provided on the outer surface of the connecting shaft 22; the outer side wall of the side membrane 23 is closely arranged on the inner wall of the storage cavity 11. Furthermore, there are two balls 21, which are relatively arranged at the two side ends of the connecting shaft 22. Through the positioning and guiding effect of the side membrane 23, the trajectory of the pusher 2 can be kept as consistent as possible during the movement, and the ball 21 can impact and move toward the buffer body 3.

[0046] Principle: The slurry is transported from the input pipe 101 into the storage chamber 11, and the pusher 2 moves downward and pushes the slurry into the discharge pipe 102 and into the transfer tank with a compressed air pressure of 0.3 MPa; at the same time, the pusher 2 hits the contact buffer 31 and the extrusion buffer 32 at the inner bottom of the storage chamber 11 to achieve double-acting buffering.
