Abstract
Description
Technical Field
[0001] This application relates to the technical field of sintering furnaces, and in particular to a sintering furnace for preparing lithium iron manganese phosphate. Background Art
[0002] The raw material used in lithium iron manganese phosphate batteries, lithium iron manganese phosphate, needs to go through a series of steps during processing, such as kiln sintering, crushing to make slurry, and drying after the slurry is made.
[0003] The quality of lithium iron manganese phosphate has a great relationship with temperature control. Since the sintering process of lithium iron manganese phosphate generally requires strict temperature control, and at the same time, considering factors such as energy conservation and preventing the working environment temperature from being too high, the sintering furnace for preparing lithium iron manganese phosphate usually requires a relatively enclosed sintering space during heating. At the same time, automated feeding operations also need to be considered. Therefore, when continuously producing, how to open the sintering furnace in time during feeding and how to close the sintering furnace in time after feeding are also issues that need to be considered. Summary of the Invention
[0004] The purpose of this application is to provide a sintering furnace for preparing lithium iron manganese phosphate.
[0005] To achieve the above object, the technical solution adopted in this application is: a sintering furnace for preparing lithium iron manganese phosphate, including a sintering furnace body and a feeding mechanism. An identification mechanism is provided between the feeding mechanism and the sintering furnace body. The sintering furnace body is provided with a feed baffle with an electric control switch. The identification mechanism is electrically connected to the feed baffle. When the feeding mechanism transports the material box close to the sintering furnace body, the material box acts on the identification mechanism to electrically control the opening of the feed baffle.
[0006] As a preference, the identification mechanism includes a shaft rod elastically installed near the feed baffle and a travel structure for triggering electric control. The shaft rod includes two ends. One end acts on the approaching material box, and the other end faces the travel structure. The material box approaches and finally acts on one end of the shaft rod, causing the shaft rod to rotate around the axis and elastically compress. When the shaft rod rotates, the other end acts on the travel structure, and the travel structure is triggered to open the feed baffle.
[0007] As a preference, an outer frame body is provided on the outside of the sintering furnace body. The outer frame body forms a travel cavity. One end of the shaft rod is inserted into the travel cavity. The travel structure is arranged on one side wall surface of the travel cavity. When the shaft rod rotates elastically and compresses, the end of the shaft rod inserted into the travel cavity acts on the travel structure.
[0008] Further preferably, the stroke structure includes two mutually sleeved boxes, and a spring is arranged between the two boxes, and the outer wall surface of the box closer to the shaft rod is an inclined surface.
[0009] As another preference, the recognition mechanism includes a pressure sensor arranged on the feeding mechanism.
[0010] As a preference, a driving mechanism for driving the feeding baffle to lift is arranged on the sintering furnace body, and the driving mechanism is electrically connected with the recognition mechanism.
[0011] Further preferably, the driving mechanism includes a fixing frame fixedly installed on the sintering furnace body, a transmission rod is arranged inside the fixing frame, the transmission rod is connected to a slider, the slider is slidably arranged in the inner cavity of the fixing frame, and the slider is connected to the feeding baffle.
[0012] Further preferably, the transmission rod is a lead screw, the fixing frame is provided with a motor for rotating the lead screw, and the slider is threadedly connected to the lead screw.
[0013] Further preferably, the slider is provided with a hinge part, the hinge part is rotatably installed on the slider, when installed, the hinge part rotates on the side closer to the feeding baffle, and a fixing part is arranged to detachably fix the hinge part to the feeding baffle.
[0014] Further preferably, the fixing part is a bolt limited at the end of the hinge part, and a threaded hole is opened at a set position on the feeding baffle, and the bolt is in fit connection with the threaded hole during fixing.
[0015] Compared with the prior art, the beneficial effects of the present application are as follows:
[0016] Through the arrangement of the recognition mechanism, when the material box is sent by the feeding mechanism to be close to the feeding baffle of the sintering furnace body, the sintering furnace body automatically recognizes and opens the feeding baffle, so that the material box can enter the sintering furnace body in time, thereby realizing automatic feeding. The feeding process is simple and does not require manual operation.
[0017] As the material box advances, after the set shaft rod rotates to a certain angle, the material box will pass through the shaft rod. At this time, the shaft rod will elastically reset, and when the shaft rod rotates, it will complete the action on the stroke structure, thereby triggering the electric control to open the feeding baffle; as for the closing of the feeding baffle, it can be set to close after the feeding baffle is opened for a certain time, or it can be set to close the feeding baffle when the stroke structure trigger ends (that is, when the shaft rod starts to reset).

[0027] Embodiment:
[0028] Refer toFigures 1 to 4 , this embodiment provides a sintering furnace for preparing lithium iron manganese phosphate, including a sintering furnace body 7 and a feeding mechanism 1. As Figure 1 shown, there is also a discharging mechanism 8 on the left side of the sintering furnace body 7, and an inner conveying mechanism 9 is also provided in the sintering furnace body 7. These conveying mechanisms can all be set as the structure of a conveyor belt or a conveying roller, but the conveying mechanism located in the sintering furnace body 7 also needs to consider the heat-resistant working conditions. An identification mechanism 4 is arranged between the feeding mechanism 1 and the sintering furnace body 7. The sintering furnace body 7 is provided with a feeding baffle 6 with an electric control switch. The identification mechanism and the feeding baffle 6 are electrically connected. When the feeding mechanism 1 transports the material box 3 close to the sintering furnace body 7, the material box 3 acts on the identification mechanism to electrically control the opening of the feeding baffle 6. Through the setting of the identification mechanism 4, when the material box 3 is sent by the feeding mechanism 1 to be close to the feeding baffle 6 of the sintering furnace body 7, the sintering furnace body 7 automatically identifies and opens the feeding baffle 6, so that the material box 3 can enter the sintering furnace body 7 in time, thereby realizing automatic feeding. The feeding process is simple and does not require manual operation.
[0029] Specifically, the identification mechanism 4 includes a shaft rod 41 elastically installed near the feeding baffle 6 and a stroke structure 10 for triggering electric control. The shaft rod 41 includes two ends, one end of which acts on the nearby material box 3, and the other end is opposite to the stroke structure 10; the material box 3 approaches and finally acts on one end of the shaft rod 41, so that the shaft rod 41 rotates around the axis and is elastically compressed. When the shaft rod 41 rotates, the other end acts on the stroke structure 10, and the stroke structure 10 is triggered to open the feeding baffle 6. By setting the elastically installed shaft rod 41, obviously the shaft rod 41 is rotatably installed. The elastic installation means that it will be elastically compressed when an external force acts on the rotation of the shaft rod 41, and the shaft rod 41 can be reset when the external force is small, so as to meet the need for continuous feeding. This external force is the pushing force on one end of the shaft rod 41 when the material box 3 passes by. As the material box 3 advances, after the shaft rod 41 rotates to a certain angle, the material box 3 will pass through the shaft rod 41. At this time, the shaft rod 41 will elastically reset, and when the shaft rod 41 rotates (before resetting), it completes the action on the stroke structure 10, thereby triggering electric control to open the feeding baffle 6; as for the closing of the feeding baffle 6, it can be set to close after the feeding baffle 6 is opened for a certain time, or it can be set to close the feeding baffle 6 when the triggering of the stroke structure 10 ends (that is, when the shaft rod 41 starts to reset).
[0030] As Figure 1 , Figure 2 shown, an outer frame body 11 is arranged outside the sintering furnace body 7. The outer frame body 11 forms a stroke cavity (that is, the inner cavity of the outer frame body 11). One end of the shaft rod 41 is inserted into the stroke cavity. As Figure 2 shown, the stroke structure 10 is arranged on one side wall surface of the stroke cavity ( Figure 2 is the left side wall surface). When the shaft rod 41 rotates for elastic compression, as Figure 2The rotation is counterclockwise. At this time, one end of the shaft rod 41 inserted into the stroke cavity rotates counterclockwise (i.e., Figure 2 rotates to the left), which will act on the stroke structure 10, thereby triggering the electric control to open the feeding baffle 6. As for how to rotate the shaft rod 41 and install it elastically, as Figure 2 shown, a torsion spring 42 can be set at the installation position of the shaft rod 41.
[0031] As Figure 2 shown, the stroke structure 10 includes two mutually sleeved boxes, and a spring is arranged between the two boxes. The outer wall surface of the box close to the shaft rod 41 is an inclined surface. The spring can ensure that after the action of the shaft rod 41 disappears, the two boxes return to their original state. The set inclined surface can cooperate with the end of the shaft rod 41 over a larger area, thereby ensuring the stability of the cooperation.
[0032] In order to ensure that the material box is in the middle position of the feeding mechanism 1 during feeding, guide frames 2 can be arranged on both sides of the feeding mechanism 1 as Figure 1 shown.
[0033] The identification mechanism of this embodiment can also be set as a pressure sensor. The feeding mechanism 1 can be set as a conveyor belt or a conveyor roller for feeding. The feeding mechanism 1 must be provided with a rotating shaft for rotation, and a pressure sensor can be set at the rotating shaft. In this way, when the material box 3 passes by, the rotating shaft will definitely be subjected to a pressure effect, so that it can sense and make a reaction. In some embodiments, it can also be simply replaced with other types of sensors such as a laser sensor, as long as it can identify the position of the material box 3 and make a reaction.
[0034] As Figure 1 、 Figure 3 shown, a driving mechanism 5 for driving the feeding baffle 6 to lift and lower is arranged on the sintering furnace body 7. The driving mechanism 5 is electrically connected to the identification mechanism 4. The driving mechanism 5 includes a fixed frame fixedly installed on the sintering furnace body 7. A transmission rod 51 is arranged inside the fixed frame. The transmission rod 51 is connected to a slider 52. The slider 52 is slidably arranged in the inner cavity of the fixed frame. The slider 52 is connected to the feeding baffle 6. Preferably, the transmission rod 51 is a lead screw. The fixed frame is provided with a motor for rotating the lead screw. The slider 52 is threadedly connected to the lead screw. After the identification mechanism identifies that the material box 3 reaches the specified position, the transmission rod 51 drives the slider 52 to lift and lower, and further enables the feeding baffle 6 to lift and lower, that is, the motor rotates to make the lead screw rotate, and further enables the slider 52 to drive the feeding baffle 6 to lift and lower. Of course, a similar structure of the lead screw slider 52 can also be replaced with a structure such as a cylinder that can perform lifting adjustment.
[0035] As Figure 3As shown, the slider 52 is provided with a hinge portion 53. The hinge portion 53 is rotatably mounted on the slider 52. When installed, the hinge portion 53 rotates close to the feeding baffle 6 and is provided with a fixing portion 54 to detachably fix the hinge portion 53 to the feeding baffle 6. When a failure occurs, structures such as the motor screw table structure and the cylinder may block the feeding baffle 6, making it difficult for manual operation to open the feeding baffle 6. In this embodiment, the connection between the feeding baffle 6 and the slider 52 is achieved through a hinge portion 53, and the connection between the hinge portion 53 and the feeding baffle 6 is detachable. Therefore, when a failure occurs, only by disconnecting the connection between the hinge portion 53 and the feeding baffle 6 can the feeding baffle 6 be manually lifted and lowered through the handle 12. For example, the fixing portion 54 is a bolt that is limited at the end of the hinge portion 53, and the feeding baffle 6 is provided with a screw hole at the set position. During fixation, the bolt is connected in cooperation with the screw hole.
