Description

Technical Field

[0001] The utility model relates to the technical field of battery material processing equipment, in particular to a feeding pipe component and a reaction kettle. Background Art

[0002] The production and processing of positive electrode materials for batteries is continuous production. One of the indicators for the production of positive electrode materials is that the concentration of metal particles is less than 30ppm. The generation of magnetic foreign matter needs to be reduced during the production process. Reactors are used in the production and processing of positive electrode materials for batteries. In the current reactors, the metal feeding tube is impacted by the rotation of the material during the production process. The feeding tube is subjected to impact loads in the reactor. Due to the low structural stability of the feeding tube, the feeding tube will break after a period of use. Magnetic foreign matter and metal particles will be generated at the fracture, affecting the normal production and processing of positive electrode materials for batteries. Utility Model Content

The terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated, that is, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In addition, unless otherwise specified, "multiple" means two or more.

[0027] like Figure 1-3 As shown, the feeding pipe assembly of the first embodiment of the utility model is used to add materials into the kettle body 1, and includes a feeding pipe 2, a first sleeve 3, a second sleeve 4, a support frame 5 and a shock-absorbing sleeve 6. The feeding pipe 2 includes a feed port and a discharge port, the feed port is located outside the kettle body 1, and the discharge port is located inside the kettle body 1; the first sleeve 3 is sleeved on the outer wall of the feeding pipe 2, and the upper end of the first sleeve 3 extends out of the kettle body 1; the second sleeve 4 is sleeved on the discharge port of the feeding pipe 2, and is arranged below the first sleeve 3 at intervals; the support frame 5 is arranged in the kettle body 1, and the second sleeve 4 is fixedly connected to the inner wall of the kettle body 1 through the support frame 5; the shock-absorbing sleeve 6 is fixed to the outer wall of the feeding pipe 2, and is arranged between the first sleeve 3 and the second sleeve 4, the upper end of the shock-absorbing sleeve 6 is connected to the first sleeve 3, and the lower end of the shock-absorbing sleeve 6 is abutted against the second sleeve 4. Among them, the feeding pipe 2, the first sleeve 3, the second sleeve 4 and the support frame 5 are made of stainless steel.

[0028] When in use, since the first sleeve 3 and the second sleeve 4 are both sleeved on the outer wall of the feeding tube 2, they play a protective role; the feeding tube 2 slides downward under the action of gravity, and the shock-absorbing sleeve 6 is fixed to the outer wall of the feeding tube 2. The shock-absorbing sleeve 6 moves with the feeding tube and abuts against the second sleeve 4 to reinforce the feeding tube 2. Based on the above arrangement, when the feeding tube 2 is subjected to an impact load, the shock-absorbing sleeve 6 can play a shock-absorbing and buffering role, maintain structural stability, and reduce damage during use.

[0029] like Figure 1 As shown, in one embodiment, at least two fixing modules 7 are further included, and the fixing module 7 includes a jacket 71 and a fixing frame 72. The jacket 71 is fixed to the outer wall of the first sleeve 3, and the jacket 71 is fixedly connected to the inner wall of the kettle body 1 through the fixing frame 72. Through the structural arrangement of the jacket 71 and the fixing frame 72, the first sleeve 3 can be fixed, so that the structural position of the first sleeve 3 is stable.

[0030] In one embodiment, the axes of the sheath 71, the first sleeve 3, the second sleeve 4 and the feeding pipe 2 are on the same straight line. Such an arrangement facilitates the first sleeve 3 and the second sleeve 4 to be sleeved on the outer wall of the feeding pipe 2, and the sheath 71 to be fixed on the outer wall of the first sleeve 3.

[0031] like Figure 1 and 2 As shown, in one embodiment, the shock absorbing sleeve 6 includes a sleeve body 61, a first opening provided at the upper end of the sleeve body 61, a second opening provided at the lower end of the sleeve body 61, and a filling layer 62 provided in the sleeve body 61, the first opening is installed on the outer wall of the first sleeve 3, and the filling layer 62 is provided on the outer wall of the feeding tube 2. Specifically, the filling layer 62 is made of elastic plastic or rubber material, so as to have a buffering effect.

[0032] Specifically, in one embodiment, the shock-absorbing sleeve 6 further includes a fixing bolt 63, one end of which passes through the sleeve body 61 and is installed in the filling layer 62. The sleeve body 61 is made of stainless steel, and the side wall has a threaded hole for installing the fixing bolt 63. When one end of the fixing bolt 63 is screwed through the threaded hole and tightly abuts against the filling layer 62, the filling layer 62 can be fixed to the outer wall of the feeding pipe 2.

[0033] Specifically, in one embodiment, the shock absorbing sleeve 6 further includes a buffer ring 64, which is sleeved on the outer wall of the feeding tube 2 and sealed in the second opening, and the buffer ring 64 abuts against the upper end of the second sleeve 4. The buffer ring 64 is fixed to the filling layer 62 with glue, and the buffer ring 64 has a protective function for the filling layer 62, and the buffer ring 64 is made of stainless steel. When the buffer ring 64 is squeezed by the second sleeve 4, the squeezing force will be transmitted to the buffer layer 62, so as to achieve the effect of buffering and shock absorption.

[0034] In one embodiment, the feeding pipe 2 is inclined from top to bottom in a direction away from the inner wall of the kettle body. Specifically, the discharge port of the feeding pipe 2 is close to the stirring rod of the reactor, which is conducive to stirring the materials evenly.

[0035] Specifically, in one embodiment, a sleeve hole 41 is provided in the second sleeve 4, and the top of the sleeve hole 41 is conical. The above structure allows the bottom end of the feeding tube 2 to slide into and be installed in the sleeve hole 41 of the second sleeve 4.

[0036] Specifically, in one embodiment, the side wall of the second sleeve 4 is provided with a groove 42, which is connected to the sleeve hole 41. During operation, the material discharged from the discharge port of the feeding pipe 2 can be discharged from the groove 42 along the sleeve hole 41, which is conducive to stirring and homogenizing the material.

[0037] The reactor of the second embodiment of the utility model comprises a reactor body 1, a stirring rod 8 and the above-mentioned feeding pipe assembly. The stirring rod 8 is installed in the reactor body 1 to stir and homogenize the material input by the feeding pipe assembly. The setting of the feeding pipe assembly makes the internal structure of the reactor stable and reduces the damage during use.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
