Description
Technical Field
[0001] The invention relates to the technical field of devices for preparing lithium manganate, and in particular to a device for continuously preparing lithium manganate by a high-temperature solid phase method. Background Art
[0002] The high-temperature solid-phase method is a process in which solid raw materials such as lithium source and manganese source are mixed evenly in a certain proportion, and then calcined at a high temperature to cause a solid-phase reaction between the raw materials to generate lithium manganate.
[0003] When using a high-temperature furnace to calcine and prepare lithium manganese oxide, a uniformly stirred mixture of manganese source particles and lithium source particles is usually poured into a feed hopper, and then loaded into the interior of the high-temperature furnace for calcination and preparation to form lithium manganese oxide. The prepared lithium manganese oxide is discharged from a discharge pipe. When loading, if too much mixture of manganese source particles and lithium source particles is put in, the mixture at the top of the feed hopper will squeeze the mixture at the bottom of the feed hopper, so that the gap between the manganese source particles and the lithium source particles in the mixture is reduced to form a whole, thereby stacking and blocking at the bottom outlet of the feed hopper, affecting the loading speed of the mixture of manganese source particles and lithium source particles, and reducing the loading efficiency and the production efficiency of preparing lithium manganese oxide. Summary of the invention
[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a device for continuously preparing lithium manganate by a high-temperature solid phase method.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a device for continuously preparing lithium manganate by a high-temperature solid phase method, comprising a high-temperature furnace and a feed hopper, the outer surface of the high-temperature furnace is provided with a discharge pipe, the outer surface of the high-temperature furnace is provided with a controller, one side of the controller is provided with a display screen, one side of the controller is provided with a plurality of control keys, an anti-blocking device is provided between the top inlet of the high-temperature furnace and the outlet of the feed hopper, one side of the controller is provided with a protective device, the anti-blocking device comprises an anti-blocking cover, the two ends of the anti-blocking cover are respectively fixedly connected to the top of the high-temperature furnace and the bottom of the feed hopper, the inner wall of the anti-blocking cover is symmetrically penetrated with an impeller, one end of the impeller is fixedly connected to a worm gear, and one side of the anti-blocking cover is symmetrically fixedly connected to a first support A worm is connected between one side of the two first brackets, and the spiral teeth at both ends of the worm are in opposite directions. The outer surface of the worm is meshed with the outer surface of the worm wheel, one end of the worm is fixedly connected to a motor, one side of the motor is fixedly connected to one side of one of the first brackets, one end of the impeller is fixedly connected to a fan gear, and the second brackets are symmetrically fixedly connected on both sides of the anti-blocking cover, a knocking hammer is connected between one side of the two second brackets, one end of the knocking hammer is fixedly connected to a circular gear, the outer surface of the circular gear is meshed with the outer surface of the fan gear, and a torsion spring is sleeved on the outer surface of one end of the knocking hammer, and the two ends of the torsion spring are respectively fixedly connected to one side of one of the second brackets and one side of the circular gear.
[0006] The effect achieved by the above components is: by setting the anti-blocking device, when using a high-temperature furnace to calcine lithium manganese oxide, the evenly stirred mixture of manganese source particles and lithium source particles is usually poured into the feed hopper, and then the motor is started to drive the worm to rotate on the first bracket, and then drive the two worm wheels to rotate in opposite directions, so that the two impellers can be driven to rotate in opposite directions in the inner wall of the anti-blocking cover, and the mixture of manganese source particles and lithium source particles falling on the inner wall of the anti-blocking cover is stirred and discharged at intervals, so that the mixture at the outlet of the feed hopper is in a state of motion and is not easily squeezed and then stopped to cause blockage, which is convenient for loading. At the same time, when the impeller rotates, it will drive the fan gear to rotate, and then drive the circular gear to rotate. The rotation of the circular gear can drive the percussion hammer to rotate on the second bracket and knock one end of the hammer on the feed hopper. The outer surface causes the inner wall of the feed hopper to vibrate, which can prevent the mixture from piling up at the outlet of the feed hopper for a second time, thereby improving the feeding speed of the mixture of manganese source particles and lithium source particles and the production efficiency of preparing lithium manganese oxide. When the striking hammer rotates, the torsion spring will be deformed. When the fan gear is completely disengaged from the circular gear, the torsion spring will drive the striking hammer to reset, making it convenient to rotate and strike the outer surface of the feed hopper next time, thereby achieving the effect of reciprocating striking. The hammer is then loaded into the interior of the high-temperature furnace, and the high-temperature furnace is started for heating by operating the control keys on the controller. The controlled time and temperature will be displayed on the display screen. After the high-temperature furnace is started, the internal manganese source particles and lithium source particles will be calcined and prepared to form lithium manganese oxide, which is then discharged from the discharge pipe.

[0009] Preferably, one side of each of the two first brackets and the second bracket is fixedly connected with a bearing, and the inner rings of the two pairs of bearings are fixedly connected to the outer surfaces of both ends of the worm and the striking hammer respectively.
[0010] The effect achieved by the above components is that by arranging the bearings, the rotational wear between the worm and the percussion hammer and the first bracket and the second bracket respectively can be reduced, thereby increasing the service life of both.
[0011] Preferably, a protective cover is fixedly connected to one side of one of the first brackets, and the motor is arranged in the inner wall of the protective cover.

In this way, it is not easy to accidentally touch the control keys when not in use or after control, affecting the use of the high-temperature furnace. At the same time, it is also not easy to hit the display screen, causing damage, thereby increasing the service life of the controller and the high-temperature furnace.
[0015] Preferably, a handle block is fixedly connected to one side of the protective cover, and a cross-section of the handle block is U-shaped.
[0016] The effect achieved by the above components is: by providing the handle block, the contact area of one side of the protective cover can be increased, and when the protective cover needs to be removed or installed, it is convenient to manually grasp one side of it.
[0017] Preferably, a limiting block is symmetrically fixedly connected to one side of the controller, and the limiting block is fixed on one side of the entrance of the card slot in an inclined manner.
[0018] The effect achieved by the above components is: by setting the limit block, the area at the entrance of the card slot can be increased, so that the two ends of the protective cover can be quickly aligned and inserted.
[0019] Preferably, a sponge block is fixedly connected to one side of the protective cover, and the sponge block is arranged on a side of the protective cover away from the handle block.
[0020] The effect achieved by the above components is: by setting the sponge block, when the two ends of the protective cover are slid up and down in the two card slots to be removed or installed, the sponge block will move back and forth on the surface of the display screen to wipe off the dust attached to its surface, making it convenient for daily maintenance.
[0021] Compared with the prior art, the advantages and positive effects of the present invention are: In the present invention, by arranging an anti-blocking device, when a high-temperature furnace is used to calcine and prepare lithium manganese oxide, the rotation of the two impellers can make the mixture at the outlet of the feed hopper in a moving state and not easily squeezed and then stopped to cause blockage, which is convenient for feeding.
