Description

Technical Field

[0001] This utility model relates to the field of ingredient preparation technology, specifically to a quantitative feeding system for powdered materials. Background Technology

[0002] In the production of refractory bricks, different raw materials need to be batched. Traditional batching methods often involve installing a baffle plate at the bottom of the feeding pipe; the baffle plate is opened during feeding and closed when not feeding. This method is highly unstable and makes it difficult to control the accurate quantity of raw materials fed. Since refractory bricks are produced by mixing different raw materials in varying proportions, any error in the quantity fed will affect the yield rate of subsequent products. Therefore, we propose a quantitative feeding system for powdered materials. Utility Model Content

[0003] The purpose of this invention is to provide a quantitative feeding system for powdered materials to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quantitative feeding system for powdered materials, including two silos, each silo having a guiding mechanism fixedly connected to its bottom, and the output ends of the two guiding mechanisms being fixedly connected to a discharge mechanism;

[0005] The material guiding mechanism includes a combined feeder, the input end of which is fixedly connected to the output end of the hopper via a connecting pipe, the output end of which is fixedly connected to the input end of the discharge mechanism via a connecting pipe, and a first pneumatic butterfly valve is fixedly installed between the combined feeder and the discharge mechanism.

[0006] Preferably, a manual slide valve is fixedly installed between the combined feeder and the hopper.

[0007] Preferably, the combined feeder includes a first housing and a second housing, which are fixedly connected. An impeller is rotatably connected inside the first housing, and an auger is rotatably connected inside the second housing. A drive motor is fixedly mounted on the side wall of the second housing. The output end of the drive motor is fixedly connected to the end of the auger. A first drive gear is fixedly mounted on the output end of the drive motor, and a second drive gear is fixedly mounted on the end of the impeller. A transmission chain meshes with the outer walls of the first and second drive gears.

[0008] Preferably, the discharge mechanism includes a top fixing body, the top of which is integrally formed with a feeding port, the bottom of which is inserted with a metering hopper, a weighing sensor is fixedly mounted between the top fixing body and the metering hopper, and a second pneumatic butterfly valve is fixedly mounted at the bottom of the metering hopper.

[0009] Preferably, the number of weighing sensors is at least four sets, and the four sets of weighing sensors are evenly distributed in a circle around the center of the weighing hopper.

[0010] Preferably, a pneumatic hammer is fixedly mounted on the side wall of the metering hopper.

[0011] Preferably, a limiting component is fixedly assembled between the top fixing body and the measuring hopper. The limiting component includes a limiting block, which is fixedly connected to the four corners of the top fixing body. A limiting frame is fixedly connected to the four corners of the measuring hopper, and the limiting frame passes through the limiting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: a quantitative feeding system for powdered materials. This system is equipped with two sets of guiding mechanisms. During use, by opening the guiding mechanisms respectively, the materials in the corresponding bins can enter the metering hopper for weighing. After reaching the set weight, the materials in the two bins can be batched. This utility model can realize the proportioning of different materials by weight, reduce feeding errors, and improve the yield of products produced from the materials.

[0013] Compared to granular feeding systems, this system is primarily used for feeding powdered materials. It employs a combined feeder as the main material guiding device, which is fully sealed to effectively prevent dust overflow and ensure a safe working environment. A pneumatic butterfly valve further seals the guiding mechanism. Due to the low weight of powdered materials, a flapper butterfly valve effectively controls the opening and closing of the guiding mechanism. If a gate valve were used, dust would accumulate in the gap between the gate and the valve body over time, preventing the valve from opening and affecting material feeding.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a technical solution: a quantitative feeding system for powdered materials, including two silos 1. The silos 1 are used to store powdered refractory brick production materials. The bottom of each of the two silos 1 is fixedly connected to a guiding mechanism 2. The outlet of the silo 1 is fixedly connected to the input end of the guiding mechanism 2. The output ends of the two guiding mechanisms 2 are fixedly connected to a discharge mechanism 3. The two silos 1 are used to store different types of powdered refractory materials. When it is necessary to perform batching operations, the guiding mechanism 2 guides the powdered materials entering the discharge mechanism 3. The discharge mechanism 3 can weigh the materials entering it. After the set material ratio weight is reached, the materials can be discharged.

[0021] like Figure 1 As shown, the material guiding mechanism 2 includes a combined feeder 21. The input end of the combined feeder 21 is fixedly connected to the discharge port of the hopper 1 through a connecting pipe, and the output end of the combined feeder 21 is fixedly connected to the discharge mechanism 3 through a connecting pipe. A first pneumatic butterfly valve 22 is fixedly installed between the combined feeder 21 and the discharge mechanism 3. In this material guiding mechanism 2, the first pneumatic butterfly valve 22 is used to seal the space between the combined feeder 21 and the discharge mechanism 3. Compared with the feeding system for granular materials, the pneumatic butterfly valve replaces the pneumatic slide gate valve. The pneumatic butterfly valve is in the form of a flap. If a slide gate type pneumatic slide gate valve is used, dust will be sealed between the slide gate and the valve body after long-term use, thus affecting the opening and closing of the valve.

[0022] like Figure 4As shown, the combined feeder 21 includes a first housing 211 and a second housing 212, which are fixedly connected. An impeller 213 is rotatably connected inside the first housing 211, and an auger 214 is rotatably connected inside the second housing 212. A drive motor 215 is fixedly mounted on the side wall of the second housing 212. The output end of the drive motor 215 is fixedly connected to the end of the auger 214 via a coupling. The drive motor 215 is electrically connected to an external power supply and an external controller. The drive motor 215 can drive the auger 214 to move within the second housing 212, thus feeding the powder. The powdered material is transported. The output end of the drive motor 215 is fixedly equipped with a first drive gear 216, and the end of the impeller 213 is fixedly equipped with a second drive gear 217. The outer walls of the first drive gear 216 and the second drive gear 217 are sleeved with a transmission chain 218 that meshes with them. When the output end of the drive motor 215 is activated, the impeller 213 can be activated within the first housing 211 through the transmission of the first drive gear 216, the second drive gear 217 and the transmission chain 218. The action of the impeller 213 can achieve uniform feeding of the powdered material.

[0023] A manual slide valve 23 is fixedly installed between the first housing 211 and the hopper 1. The manual slide valve 23 is used to seal the hopper 1 to prevent the material in the hopper 1 from continuing to flow downwards and causing blockage to the lowered combined feeder 21 when the power is off.

[0024] like Figure 2 As shown, the discharge mechanism 3 includes a top fixing body 31. The top of the top fixing body 31 has integrally formed inlet ports 32 symmetrically distributed on the left and right sides. The inlet ports 32 are used to connect and fix to the discharge end of the guiding mechanism 2. A metering hopper 33 is inserted into the bottom of the top fixing body 31. Material enters the metering hopper 33 through the inlet ports 32. Weighing sensors 34 are fixedly mounted on the side wall of the top fixing body 31. There are four sets of weighing sensors 34, which are evenly distributed circumferentially around the center of the metering hopper 33. The input end of the weighing sensor 34 is fixedly connected to the side wall of the weighing hopper 33, and the output end of the weighing sensor 34 is connected to the external controller for electrical signal. When the material enters the weighing hopper 33, the weight of the material can be weighed by the weighing sensor 34. When the material reaches the set feeding value, the weighing sensor 34 sends an electrical signal to the external controller. The external controller controls the first pneumatic butterfly valve 22 to close and stop feeding. The external controller can be an integrated controller such as a computer or a microcontroller, which can control the opening and closing of each device separately.

[0025] A second pneumatic butterfly valve 35 is fixedly installed at the bottom of the metering hopper 33. The input end of the second pneumatic butterfly valve 35 is electrically connected to an external controller. The opening and closing of the second pneumatic butterfly valve 35 can be controlled by the external controller. When the second pneumatic butterfly valve 35 is opened, the material in the metering hopper 33 can be discharged downward from the discharge port at the bottom.

[0026] A pneumatic hammer 36 is fixedly mounted on the side wall of the metering hopper 33. The pneumatic hammer 36 is electrically connected to an external controller. When the metering hopper 33 discharges material, the external controller can control the pneumatic hammer 36 to open. The vibration generated by the metering hopper 33 after the pneumatic hammer 36 is opened can prevent the material from being blocked at the second pneumatic butterfly valve 35, making it easier for the metering hopper 33 to discharge material.

[0027] like Figure 1 and Figure 3 As shown, a limiting component 4 is installed between the top fixed body 31 and the measuring hopper 33. The limiting component 4 limits the movement stroke between the measuring hopper 33 and the top fixed body 31, preventing the assembly position of the measuring hopper 33 and the top fixed body 31 from shifting after the air hammer 36 is opened, thus affecting the weighing accuracy of the load cell 34. The limiting component 4 includes a limiting block 41, which is welded and fixed at the four corners of the top fixed body 31. A limiting frame 42 is welded and fixed at the four corners of the measuring hopper 33. The limiting frame 42 passes through the limiting block 41 and is slidably connected to the limiting block 41. The limiting frame 42 is I-shaped. Through the cooperation of the limiting block 41 and the limiting frame 42, the assembly position between the measuring hopper 33 and the top fixed body 31 can be effectively limited, while not affecting the material entering the measuring hopper 33. The measuring hopper 33 moves along the vertical direction, which facilitates the weighing process of the load cell 34.

[0028] Working Principle: This system is mainly used for batching powdered refractory brick production raw materials. The specific batching process is as follows: First, the first pneumatic butterfly valve 22 in the material guiding mechanism 2 is opened, and then the corresponding combined feeder 21 is opened. After the combined feeder 21 is opened, the powdered material in the hopper 1 enters the first housing 211. Through the rotation of the impeller 213, the material is evenly fed into the second housing 212. Then, the auger 214 transfers the material in the second housing 212, allowing the material to enter the discharge mechanism along the bottom discharge port. Material is discharged from the metering hopper 33. After entering the metering hopper 33, the material is weighed by the weighing sensor 34. Once the specified weight is reached, the first pneumatic butterfly valve 22 is closed. Then, the above steps are repeated for the discharge of material from the other side hopper 1. This can complete the batching of two different powdered materials in the metering hopper 33. After the batching is completed, the second pneumatic butterfly valve 35 is opened to allow the material to be conveyed from the bottom of the metering hopper 33 to the next processing stage. At the same time, the air hammer 36 is opened to vibrate the metering hopper 33 and accelerate the downward discharge of material from the metering hopper 33.
