Description

Technical Field

[0001] The utility model relates to the technical field of feeding control, in particular to a feeding metering device and mixing equipment. Background Art

[0002] In various industrial processing processes, it is often necessary to use automatic feeding equipment such as functional feeding machines to automatically feed materials, realize processing automation, save workers' labor intensity, and reduce labor costs. In many cases, materials need to be weighed with metering equipment before feeding to ensure the accurate proportion of various materials used in processing. In response to this, some devices specifically used for feeding, weighing and metering have appeared on the market.

[0003] However, the existing feeding and weighing devices are very likely to cause the discharge port to be blocked, and there are problems such as the material adhering to the bottom plate of the silo, making it difficult to bridge and discharge the material. For example, in the lithium iron phosphate industry, lithium iron phosphate is usually prepared by carbon thermal reduction. After polyethylene glycol (PEG) carbon source is mixed with iron phosphate and lithium carbonate, it is sintered in a nitrogen atmosphere to form a stable carbon-coated lithium iron phosphate. Since PEG as a carbon source requires precise weighing, and PEG is generally in the form of 2-5mm flakes, its fluidity is very poor. Using conventional feeding and weighing devices for metering and weighing, problems such as blockage and difficulty in discharging are more serious. Utility Model Content

[0036] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0037] Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. The various technical features in the utility model can be combined interchangeably without conflicting with each other.

[0038] First, refer to Figures 1 to 5 The embodiment of the utility model proposes a feeding metering device, which can weigh materials, and its discharge port is not prone to blockage, material feeding difficulties, etc., so that the material can smoothly pass through the discharge port into the downstream device.

[0039] The feeding and metering device of this embodiment includes a feeding assembly 100, an activation assembly 200 and a weighing component 300. The feeding assembly 100 is arranged above the activation assembly 200. The feeding assembly 100 is mainly used to fluidize the material to avoid the formation of bridges and the difficulty of feeding; the activation assembly 200 is mainly used to activate the material to avoid the occurrence of material blockage and the like; the weighing component 300 is used to obtain the weight information of the feeding assembly 100 and the activation assembly 200, including the structural weight of the feeding assembly 100 and the activation assembly 200 and the weight of the material located in the feeding assembly 100 and the activation assembly 200.

[0040] The feeding assembly 100 includes a silo 110, a silo door 120 and a fluidizing structure 130. The silo 110 is hollow and has a feeding cavity, and is provided with a feeding port 123, the feeding port 123 is connected to the feeding cavity, the silo door 120 is movably connected to the silo 110, and the silo door 120 is used to open or close the feeding port 123. The fluidizing structure 130 is connected to the silo 110, and can pass flowing gas into the feeding cavity to increase the fluidity of the material and prevent the occurrence of bridging.

[0041] After the door 120 is opened, workers can put materials into the feeding chamber through the feeding port 123. When the door 120 is closed, it can prevent the leakage of materials from the feeding port 123, which may cause incorrect weighing and environmental pollution. In particular, when the fluidized structure 130 is used to introduce flowing gas into the feeding chamber, material dust will flow in the feeding chamber, and it is even more necessary to use the door 120 to close the feeding port 123 to prevent material dust from being discharged from the feeding port 123.

[0042] The activation assembly 200 includes a hopper 210, a vibration component 230, a connecting component 240 and a first valve 220. The upper end of the connecting component 240 is connected to the silo 110, and the lower end is connected to the hopper 210, and a soft connection between the silo 110 and the hopper 210 is realized by the connecting component 240. The hopper 210 is hollowly provided with a discharge cavity, and the discharge cavity is connected with the feeding cavity, and a discharge port is provided at the lower end of the discharge cavity. The first valve 220 is connected to the hopper 210, and the first valve 220 is used to open or close the discharge port. The vibration component 230 is connected to the hopper 210, and it can provide vibration power for the hopper 210.

[0043] The weighing component 300 is connected to the silo 110. In this embodiment, the weighing component 300 includes four weighing modules 310, which are respectively arranged on the front, rear, left and right sides of the silo 110, and can support the entire feeding and metering device.

[0044] When no material is added, the weighing component 300 can weigh other components of the feeding and metering device. At this time, the weight information obtained by the weighing component 300 is the component weight. When the feeding and metering device of this embodiment is used for feeding and weighing, the first valve 220 is closed first, and then the door 120 is opened, and the material is added to the feeding chamber, and then the weighing component 300 performs the weighing action. The weight obtained minus the component weight is the weight of the material added to the feeding chamber, and the material weight is set as M1.

[0045] It is understandable that the discharge port is used to discharge materials and connect to downstream devices. When the first valve 220 is opened, the material enters the feeding chamber through the feeding port 123, falls into the material chamber, and is finally discharged from the discharge port. Since the fluidizing structure 130 is provided in this embodiment, the fluidizing structure 130 introduces flowing gas into the feeding chamber, which can increase the fluidity of the material to prevent bridging, thereby allowing the material to fall more smoothly into the discharge chamber. And since a vibration component 230 is provided, the vibration component 230 can vibrate the hopper 210 to prevent the material from blocking the discharge port.

[0046] In this embodiment, the vibration component 230 is a vibration motor, which drives the hopper 210 to vibrate, thereby achieving the effect of assisting material discharge and effectively avoiding material blockage and incomplete material discharge.

[0047] After the material is discharged, it is weighed again by the weighing component 300. The weighed weight minus the component weight is the weight of the material remaining in the feeding chamber and the discharging chamber at this time. Suppose the material weight is M2. When M2 is less than a certain range, it can be considered that the discharge is complete. Suppose the actual discharged material weight is m. Through the simple formula m=(M1-M2), the actual discharged material weight can be accurately obtained.

[0048] In some embodiments, the connecting member 240 includes an upper connecting ring 241, a lower connecting ring 242 and a spring 243. The upper end of the spring 243 is connected to the upper connecting ring 241, which is connected to the silo 110, and the lower end of the spring 243 is connected to the lower connecting ring 242, which is connected to the hopper 210.

[0049] By realizing a soft connection between the hopper 210 and the silo 110 through the upper connecting ring 241, the lower connecting ring 242 and the spring 243, the influence of the vibration of the hopper 210 on the silo 110 can be reduced, thereby avoiding the influence of the vibration of the hopper 210 on the weighing component 300, improving the weighing accuracy, and protecting the weighing component 300. At the same time, it can strengthen the vibration of the hopper 210 and further avoid material blockage.

[0050] In this embodiment, the vibration component 230 is connected and installed on the lower connection ring 242. The connection component 240 formed by the spring 243, the upper connection ring 241, and the lower connection ring 242 has a simple structure and can provide support for the silo 110 and the hopper 210. Moreover, the connection between the upper connection ring 241 and the lower connection ring 242 is realized by the spring 243, so that the soft connection between the silo 110 and the hopper 210 is realized, and the vibration of the hopper 210 has a small effect on the vibration of the silo 110, thereby avoiding the influence of the vibration of the hopper 210 on the weighing component 300, and at the same time, the vibration of the hopper 210 can be strengthened to further avoid the situation of material blockage.

[0051] In this embodiment, the silo 110 and the hopper 210 are connected by bolts, and the bolts are passed through the upper connecting ring 241 and the lower connecting ring 242. The upper and lower ends of the bolts are locked by nuts respectively. When the hopper 210 vibrates up and down, the lower connecting ring 242 can vibrate up and down under the restriction of the bolts without causing the upper connecting ring 241 to vibrate. By setting the bolts, the connection component 240, the silo 110 and the hopper 210 can be prevented from falling off.

[0052] In this embodiment, rubber pads are respectively provided between the nut and the hopper 210 and between the nut and the silo 110, which can further realize the soft connection between the hopper 210 and the silo 110 and further reduce the impact of the vibration of the hopper 210 on the silo 110. The rubber pads can be made of rubber, latex or other materials and have good elasticity.

[0053] In some embodiments, the connecting component 240 also includes a positioning rod 244, the lower end of the positioning rod 244 is connected to the lower connecting ring 242, the upper connecting ring 241 is provided with a limiting hole, the positioning rod 244 is passed through the limiting hole, and a locking block is provided at the upper end of the positioning rod 244, each locking rod is configured with two locking blocks, and the two locking blocks are respectively provided on the upper and lower sides of the upper connecting ring 241.

[0054] It is understandable that the setting of the positioning rod 244 provides a guarantee for the connection between the upper connecting ring 241 and the lower connecting ring 242, and avoids the failure of the hopper 210 falling off from the silo 110 due to aging or damage of the spring 243. The locking block can be a nut. When installing, the nut as the locking block should not be tightened, and a certain gap should be left between the upper connecting ring 241, which will not affect the soft connection between the hopper 210 and the silo 110, and can also play a role in ensuring safety.

[0055] In some embodiments, the fluidization structure 130 includes a fluidizer 131, a first air pipe 132, a first air bag 134, and a second valve 133. The fluidizer 131 is disposed in the feeding chamber, the first air pipe 132 is connected to the fluidizer 131, and a portion thereof extends out of the feeding chamber, the first air bag 134 is disposed outside the silo 110, and the rest of the first air pipe 132 extending out of the feeding chamber is connected, and the second valve 133 is disposed between the first air bag 134 and the first air pipe 132. When the second valve 133 is opened, the first air bag 134 can supply air to the first air pipe 132, so that the flowing gas is blown out through the fluidizer 131 inside the feeding chamber, so as to realize the fluidization of the material inside the fluidization chamber, avoid the bridging phenomenon, and facilitate the discharge of the material.

[0056] Preferably, the fluidizing structure 130 is installed at a bottom position of the silo 110 .

[0057] It is understandable that the first air pipe 132 can be fixed to the silo 110 through a U-shaped slot. In this embodiment, the first air pipe 132 is annular in the feeding chamber, and the annular portion of the first air pipe 132 is provided with a plurality of exhaust ports, which are evenly arranged along the annular portion of the first air pipe 132. A plurality of fluidizers 131 are provided, and the positions of the fluidizers 131 and the exhaust ports correspond one by one to achieve uniform fluidization of the material in the feeding chamber.

[0058] In some embodiments, the fluidizer 131 includes an upper fluidizer 131 and a lower fluidizer 131. The upper fluidizer 131 and the lower fluidizer 131 are respectively installed at the annular part of the first air pipe 132 through hoses. The hose connected to the lower fluidizer 131 is extended downward, so that the lower fluidizer 131 can be set below the upper fluidizer 131. Through the joint action of the upper fluidizer 131 and the lower fluidizer 131, the fluidization effect of the material is further improved, the material can be discharged smoothly, and abnormal situations such as bridging and blockage can be avoided.

[0059] Specifically in this embodiment, 6 upper fluidizers 131 are provided and 6 lower fluidizers 131 are provided. The upper fluidizers 131 and the lower fluidizers 131 are arranged alternately and installed at the annular part of the first air pipe 132, which effectively avoids problems such as blockage of the silo 110 and incomplete material discharge, allowing the material to enter the discharge chamber from the feeding chamber more smoothly.

[0060] It is understandable that the specific number and arrangement of the fluidizers 131 are not specifically limited here, and the number and arrangement of the fluidizers 131 can be optimized according to actual conditions, such as the volume of the feeding chamber.

[0061] In some embodiments, an air hammer 140 is further provided at the lower end of the silo 110. The air hammer 140 uses the principle of air power to strike the lower end of the silo 110, which can assist the material to flow from the feeding cavity to the discharging cavity, and prevent the material from adhering to the feeding cavity, causing material blockage or bridging. It is understandable that the vibration generated by the silo 110 being struck by the air hammer 140 is small, and is not likely to affect the weighing of the weighing component 300.

[0062] In some embodiments, the feeding metering device also includes a dust removal component 400, which can prevent the material from raising dust and polluting the surrounding environment. In this embodiment, the dust removal component 400 includes a filter 420 and a fan 410. The filter 420 is connected to the silo 110, the inlet end of the filter 420 is connected to the feeding chamber, and the outlet end is connected to the fan 410. The fan 410 can evacuate the feeding chamber, and the extracted gas is discharged after being filtered by the filter 420. The feeding chamber is in a negative pressure state, which can effectively prevent dust from being discharged and polluting the surrounding environment during the feeding process.

[0063] In some embodiments, the dust removal assembly 400 further includes a back-blowing component 430, which is provided with an air outlet, which is connected to the outlet end of the filter 420 and can blow air to the filter 420, so as to make the powdery material adhering to the filter 420 fall off, and avoid the material on the filter 420 being too thick and affecting the air extraction effect of the fan 410. It is understandable that during the entire dust removal process, the bin door 120 is in a closed state to prevent dust from polluting the surrounding environment during the dust removal process.

[0064] In this embodiment, the back-blowing component 430 includes a second air bag 432 and a second air pipe 431. The outlet end of the second air pipe 431 is the air outlet, the second air bag 432 is connected to the other end of the second air pipe 431, and the second air bag 432 is provided with a third valve 433. When the third valve 433 is opened, the second air bag 432 supplies air to the second air pipe 431, and the gas is blown from the second air pipe 431 to the filter 420.

[0065] It is understandable that the door 120 can be opened manually or automatically.

[0066] In some embodiments, the bin door 120 includes a door body 121 and a telescopic component 122, the door body 121 is hinged to the silo 110, one end of the telescopic component 122 is hinged to the door body 121, and the other end is hinged to the silo 110. It can be understood that the telescopic component 122 is used to drive the door body 121 to rotate relative to the silo 110, thereby opening or closing the feeding port 123. The door body 121 is turned over by the drive of the telescopic component 122, and there is no need for workers to open it manually, which further reduces the labor intensity of workers.

[0067] In this embodiment, the feeding port 123 is arranged on the side wall of the upper part of the silo 110, and the upper end of the door body 121 is hinged to the silo 110 through a hinge, and when the door body 121 is opened upward around the hinge, the feeding port 123 is opened, and vice versa, the feeding port 123 is closed. It is understandable that the silo 110 can also be hinged to the lower end, right end or left end of the door body 121.

[0068] In this embodiment, the telescopic component 122 is a cylinder, which is provided with a telescopic rod. When the telescopic rod is converted from a retracted state to an extended state, the door body 121 is flipped open and the feeding port 123 is opened, which can effectively prevent the door body 121 from automatically closing due to gravity during the feeding process, thereby affecting the manual feeding process; when the telescopic rod is converted from an extended state to a retracted state, the door body 121 is flipped in the opposite direction and the feeding port 123 is closed.

[0069] In this embodiment, the side surface of the feeding port 123 provided on the upper part of the silo 110 is an inclined surface, which is inclined from bottom to top toward the opposite side wall surface. The feeding port 123 is in a state of being inclined upwardly opened, which is more convenient for workers to feed materials into the feeding chamber through the feeding port 123.

[0070] In some embodiments, the door body 121 is provided with a sealing strip. When the door body 121 covers the feeding port 123 and is connected to the silo 110, the sealing strip can seal the gap between the door body 121 and the silo 110, further preventing the material in the feeding chamber from leaking out and affecting the surrounding environment, and can improve the accuracy of weighing.

[0071] In this embodiment, a support plate 150 is also installed on the side of the silo 110. The support plate 150 is located at the lower side of the feeding port 123, and can support the material bag filled with materials when feeding. The bag mouth of the material bag is extended into the feeding cavity through the feeding port 123 to realize feeding. During the feeding process, workers do not need to lift the material bag for a long time, which further reduces the labor intensity of the workers and facilitates feeding.

[0072] In some embodiments, the feeding metering device further includes a control component, which includes a display component and a controller. The display component and the weighing component 300 are electrically connected to the controller respectively. The weighing component 300 is configured to obtain weight information and send it to the controller, so that the controller controls the display component to display the weight information. Such a setting can allow workers to more intuitively understand the amount of materials used.

[0073] In some embodiments, the feeding component 100 also includes a sensor 160, which is connected to the silo 110, and its sensing end is set toward the feeding port 123. The sensor 160 is electrically connected to the controller, and can obtain the status information of the feeding port 123 and send the status information of the feeding port 123 to the controller. The controller controls the weighing component 300 to operate according to the obtained status information of the feeding port 123.

[0074] Specifically, during the feeding process, the sensor 160 detects that the feeding port 123 remains in the open state, and the weighing component 300 does not work; when the feeding is completed, the bin door 120 is closed, and the sensor 160 detects that the feeding port 123 is converted from the open state to the closed state, and the controller controls the weighing component 300 to weigh, thereby automatically obtaining M1.

[0075] In this embodiment, the sensor 160 is an infrared sensor 160, which senses whether the feeding port 123 is blocked by infrared rays, thereby obtaining status information of the feeding port 123. The sensor 160 may also be a contact sensor 160, a grating, etc., which is not specifically limited here.

[0076] In this embodiment, when the sensor 160 senses that the feeding port 123 is switched from an open state to a closed state, the controller controls the display component to display information such as "feeding completed" to provide operation prompts for the workers.

[0077] In some embodiments, the fluidizing structure 130, the vibration component 230, and the first valve 220 are electrically connected to the controller respectively, and the entire weighing and discharging process is automatically controlled by the controller. Specifically, after the feeding is completed, the weighing component 300 transmits the weight information to the controller, and the display component displays the weight M1. After obtaining M1, the controller controls the first valve 220 to open, and controls the fluidizing structure 130 and the vibration component 230 to open. The fluidizing structure 130 automatically introduces compressed air into the feeding chamber, so that the material in the feeding chamber is fluidized and falls smoothly into the discharging chamber. The vibration component 230 makes the hopper 210 vibrate, and the material in the discharging chamber can smoothly leave from the discharging port.

[0078] In the embodiment in which the dust removal component 400 is provided, the fan 410 of the dust removal component 400 is electrically connected to the controller. When the fluidizing structure 130 is used to introduce compressed air into the feeding chamber, the controller controls the fan 410 to turn on. The fan 410 extracts the gas in the feeding chamber, and the inside of the feeding chamber is in a negative pressure state, thereby avoiding air leakage and powder leakage caused by the positive pressure in the feeding chamber.

[0079] In this embodiment, the control component also includes a control panel, which is electrically connected to the controller. Workers can control the opening or closing of components such as the fluidization structure 130, the vibration component 230, the first valve 220, and the fan 410 by operating the control panel.

[0080] The worker operates the control panel to let the controller control the weighing component 300 to perform weighing. The weighing component 300 transmits the weight information to the controller, and the controller controls the display component to display the weight M2. When M2 is less than a certain range, it can be considered that the material discharge is complete. The controller controls the display component to display statements such as "material discharge is completed" and "material batching is completed", and displays the actual weight of the discharged material m, m = M1-M2. Then, the controller automatically controls the first valve 220, the vibration component 230, the fluidization structure 130, and the fan 410 to close. In this way, the automatic control of material discharge can be achieved.

[0081] In the process of fluidizing the material in the feeding chamber, the controller can control the fluidizing structure 130 to open intermittently, that is, after controlling the fluidizing structure 130 to open for a first time, the fluidizing structure 130 is controlled to close for a second time, and then the fluidizing structure 130 is opened for the first time, and the cycle is repeated until the fluidization is completed. Such a setting can effectively reduce the amount of gas in the first air bag 134, play a role in saving gas, and at the same time can also shorten the working time of the fluidizing structure 130 and extend the service life of the feeding metering device. In this embodiment, the intermittent opening of the second valve 133 is specifically controlled by the controller.

[0082] Before feeding into the feeding port 123, the worker can first operate the control panel to let the controller control the fan 410 of the dust removal component 400 to turn on. The fan 410 extracts the gas inside the feeding chamber, so that the feeding chamber is in a negative pressure state, which can effectively avoid the dust of the material from being blown out during the feeding process. During the process of the fan 410 being turned on, the controller controls the third valve 433 to be opened regularly, and the back-blowing component 430 back-blows the filter 420 to make the powder adhering to the filter 420 fall off, so as to avoid the material on the filter 420 being too thick and affecting the dust removal and air extraction effect. It is understandable that during the dust removal process before feeding, the bin door 120 remains closed. After the dust removal is completed, the controller controls the bin door 120 to open, and the worker feeds the material. After the feeding is completed, the worker operates the control panel, and the controller controls the bin door 120 to close.

[0083] In this embodiment, the first valve 220 is a butterfly valve. Since the diameter of the butterfly valve is large, the cross-sectional area of ​​the discharge port matched therewith is large, which can well avoid the bridging of the material during the discharge process. The second valve 133 and the third valve 433 are both solenoid valves. The first valve 220, the second valve 133 and the third valve 433 can all be other types of valve structures, which are not specifically limited here.

[0084] In this embodiment, the silo 110 is divided into two parts, an upper silo body 112 and a lower silo body 111, and the lower end of the upper silo body 112 is connected to the upper end of the lower silo body 111. The dust removal assembly 400 is installed in the upper silo body 112, and the feeding port 123 is set in the upper silo body 112. The weighing component 300 is connected to the upper end of the lower silo body 111, and the fluidization structure 130 is installed at the lower end of the lower silo body 111.

[0085] In some embodiments, the upper part of the hopper 210 is designed as an inverted cone-shaped bucket body 211, and a discharge pipe 212 is arranged at the lower part. The lower end of the bucket body 211 is connected to the upper end of the discharge pipe 212, and the first valve 220 is installed at the discharge pipe 212. The lower end of the discharge pipe 212 is a discharge port, and the discharge pipe 212 is installed at the center of the bucket body 211, that is, the discharge port is arranged at the center of the bottom of the hopper 210, and the bottom surface of the bucket body 211 is inclined downward from the side wall of the bucket body 211 toward the center, which is conducive to the material sliding down along the bottom surface of the bucket body 211 to the discharge pipe 212.

[0086] In some embodiments, a soft connector 250, such as soft rubber, is provided at the lower end of the discharge pipe 212. The soft connector 250 at the lower end of the discharge pipe 212 is used to connect with a downstream device, and after the material flows out through the discharge pipe 212, it can directly enter the downstream device to complete the next process. Since the downstream device is connected to the hopper 210 through the soft connector 250, the vibration of the hopper 210 will not affect the downstream device, nor will it cause damage to the downstream device.

[0087] The working process of the feeding metering device of the utility model embodiment is as follows:

[0088] The worker operates the control panel and issues a feeding instruction. The controller controls the dust removal component 400 to open and perform dust removal work before feeding. The fan 410 is turned on, and the gas in the feeding chamber is filtered by the filter 420 and then extracted, and the feeding chamber is in a negative pressure state. At the same time, the controller controls the third valve 433 to open, and the second air bag 432 blows gas to the filter 420 through the second air pipe 431 to let the powder adhering to the filter 420 fall off, so as to ensure the exhaust effect of the fan 410.

[0089] After the dust removal work is completed, the controller controls the telescopic component 122 of the warehouse door 120 to change from the retracted state to the extended state, the door body 121 of the warehouse door 120 flips upward, and the feeding port 123 is exposed. The worker can feed the material into the feeding chamber through the feeding port 123 by manual feeding or feeding by automatic equipment such as a manipulator. After the feeding is completed, the worker operates the control panel and issues a stop feeding instruction. The controller turns off the dust removal component 400 and controls the telescopic component 122 to change from the extended state to the retracted state. The door body 121 of the warehouse door 120 flips downward and covers the feeding port 123. When the sensor 160 senses that the feeding port 123 is in a closed state, the controller controls the display component to display that the feeding is completed.

[0090] After the feeding is completed, the weighing component 300 transmits the weighing signal to the controller, and the display component displays the weight M1. The worker operates the control panel and issues an instruction to start the batching. The controller controls the first valve 220 to open, and controls the vibration component 230, the fluidization structure 130, and the air hammer 140 to start. The second valve 133 of the fluidization structure 130 is opened, and the fluidizer 131 blows air into the feeding chamber to fluidize the material in the feeding chamber. The air hammer 140 knocks on the side wall of the silo 110, allowing the material adhering to the side wall of the feeding chamber to fall into the discharge chamber. The vibration component 230 provides vibration power for the hopper 210, and the hopper 210 vibrates, allowing the material entering the discharge chamber to be discharged smoothly through the discharge port.

[0091] After the material is discharged, the weighing component 300 weighs and transmits the weighing signal to the controller, and the display component displays M2. When M2 is less than the predetermined range, the controller obtains the actual discharged material weight m according to M1 and M2 and the formula m=M1-M2, and displays m on the display component. Then, the controller controls the first valve 220 to close, and controls the vibration component 230, the air hammer 140 and the fluidization structure 130, and controls the display component to display that the material discharge is completed.

[0092] The material discharged from the discharge port of the feeding metering device of this embodiment can directly enter the downstream device. The feeding metering device can take into account the functions of material weighing and material unloading, with high weighing accuracy. Moreover, in the process of unloading, material bridging and blockage can be avoided.

[0093] On the other hand, the embodiment of the utility model also proposes a mixing device, which includes a feed metering device as proposed in any of the above embodiments. It can be understood that the mixing device also includes a mixing device for mixing, that is, the downstream device of the feed metering device is the mixing device. After the material is weighed and measured by the feed metering device, the material is directly discharged into the mixing device and mixed with other materials. For example, in the lithium iron phosphate industry, the PEG carbon source is added to the mixing device with iron phosphate and lithium carbonate through a mixing device with a feed metering device, and the mixing operation is performed in the mixing device.

[0094] Since the mixing equipment is equipped with a material metering device, workers can accurately control the usage ratio of various materials and prepare products with better and more stable quality.
