Description

Technical Field

[0001] This invention relates to the field of gas-powder mixing technology, specifically a flat brush mixing and powder feeding device with mixing concentration control function. Background Technology

[0002] In gas-powder mixing equipment, the gas introduced helps to mix powder materials. Introducing gas during powder mixing can diffuse particles, improve mixing efficiency, increase uniformity, reduce the risk of dust explosions, and improve flowability. These advantages effectively improve the efficiency and quality of the mixing process, hence the widespread use of gas in powder material mixing. Secondly, introducing gas can also help improve the uniformity of powder material mixing.

[0003] However, most existing gas-powder mixing equipment is single-powder feeding and gas mixing. In addition, it has the following disadvantages: using vibrating powder feeding, it is not possible to quantitatively detect and control the concentration of gas powder; the raw material powder is prone to agglomeration, forming large particles, which affects the quality of powder-gas mixing; the powder cannot participate in the gas mixing reaction at the bottom of the reaction tank, resulting in low raw material utilization efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a flat brush mixing and powder feeding device with mixing concentration control function to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A flat grinding brush mixing and feeding device with mixing concentration control function is disclosed. The mixing and feeding device includes a machine body, a coated motor module, a flat grinding brush module, a feeding component, a screw lifting module, and an air supply component. The machine body is fastened to the coated motor module, the flat grinding brush module, the screw lifting module, and the air supply component. The coated motor module and the flat grinding brush module are fastened to each other. The coated motor module and the air supply component are connected by a pipeline. There are two sets of feeding components. The two sets of feeding components are fastened to the flat grinding brush module. The flat grinding brush module and the air supply component are connected by a pipeline. The feeding component and the screw lifting module are fastened to each other.

[0007] The motor coating module, the flat grinding brush module, the screw lifting module, and the air supply component are fixed on the machine body. The motor coating module and the air supply component are connected, and the air supply component can deliver gas into the motor coating module. The flat grinding brush module and the air supply component are also connected, and the air supply component can deliver gas into the flat grinding brush module. Since the motor coating module and the flat grinding brush module are connected in the middle, the internal pressure of the two is consistent, thus forming a stable flow. The screw lifting module pushes the feeding component to make the powder enter the flat grinding brush module. The crushed powder and the gas in the flat grinding brush module are mixed and then output to the outside of the machine body.

[0008] Furthermore, the machine body includes a frame, a motor maintenance door panel, a barrel replacement door panel, and a protective door panel. The frame is fastened to the motor covering module, the flat grinding brush module, the lead screw lifting module, and the air supply assembly, respectively. The frame is hinged to the motor maintenance door panel, the barrel replacement door panel, and the protective door panel, respectively. The motor maintenance door panel and the barrel replacement door panel are located on the side closer to the motor covering module. The motor maintenance door panel is located above the barrel replacement door panel, and the protective door panel is located on the side closer to the lead screw lifting module.

[0009] The frame is used to fix the coating motor module, the flat grinding brush module, the lead screw lifting module and the air supply component. The motor maintenance door is used to protect the coating motor module and part of the flat grinding brush module. The material cylinder replacement door is used to maintain another part of the flat grinding brush module and the feeding component. The protection door is used to protect the lead screw lifting module.

[0010] Furthermore, the encapsulated motor module includes a motor housing, a high-speed motor, a connecting cylinder, a motor coupling, and an air pipe connector. The upper end of the motor housing is fastened to the frame. The motor housing and the air pipe connector are connected by a pipe. The air pipe connector and the air supply component are connected by a pipe. A high-speed motor is installed inside the motor housing. The motor housing and the connecting cylinder are fastened to each other. The output end of the high-speed motor passes through the motor housing. The output end of the high-speed motor is fastened to the motor coupling. The motor coupling is placed inside the connecting cylinder. The motor coupling and the surface brush module are fastened to each other.

[0011] The high-speed motor is placed inside the motor housing. The output torque of the high-speed motor drives the motor coupling to rotate. The motor coupling is protected by a connecting cylinder. The connecting cylinder is placed between the motor housing and the flat brush module. The motor housing is fixed on the frame. The air pipe connector below the motor housing is connected to the air supply component, so the air supply component delivers gas to the inside of the motor housing.

[0012] Furthermore, the motor housing includes an upper cover plate, a covering cylinder, a lower cover plate, and a sealing gasket. There are two sets of sealing gaskets, which are respectively fastened to the upper cover plate and the lower cover plate. The covering cylinder is placed between the two sets of sealing gaskets and is fastened to the two sets of sealing gaskets. A high-speed motor is mounted on the lower cover plate, and the output end of the high-speed motor passes through the lower cover plate. The lower cover plate is fastened to the connecting cylinder, and the air pipe connector passes through the lower cover plate.

[0013] The motor housing consists of an upper cover plate, a sealing gasket, a covering cylinder, a sealing gasket, and a lower cover plate from top to bottom. The two sets of sealing gaskets improve the sealing between the covering cylinder and the upper and lower cover plates, preventing the exchange of air with the outside. The lower cover plate and the high-speed motor are fixed together, providing better protection for the high-speed motor. The air supply component delivers gas through the air pipe connector, passing through the lower cover plate into the motor housing.

[0014] Furthermore, the surface grinding brush module includes a cavity cover plate, a mixing cavity, a base cover plate, a connecting block, a brush disc, a spray pipe, brush bristles, an air vent block, and an air inlet connector. The cavity cover plate and the connecting cylinder are fastened together. The cavity cover plate and the mixing cavity are fastened together. The mixing cavity and the base cover plate are fastened together. An air inlet connector is provided below the base cover plate. The air inlet connector is connected to the air supply component pipe. The base cover plate and the feeding component are fastened together. One end of the connecting block is fastened together with the motor coupling. The other end of the connecting block is fastened together with the brush disc. The mixing cavity contains a brush disc. Brush bristles are provided below the brush disc. The spray pipe is placed between the mixing cavity and the base cover plate. One end of the spray pipe passes through the frame. An air vent block is provided above the base cover plate. The air vent block is placed below the brush disc.

[0015] The cavity cover and connecting cylinder are fixed. A motor coupling is installed inside the connecting cylinder, and the coupling block is fixed to the brush disc. The brush disc is installed inside the cavity. The motor coupling and coupling block are fixed. A high-speed motor provides rotational power, causing the motor coupling to drive the brush disc to rotate. An air vent block is fixed to the base cover and positioned between the base cover and the brush disc. The feeding assembly pushes powder into the base cover. The rotating brush disc causes the bristles to contact and break the powder, causing it to adhere to the air vent block. Through the connection between the air supply assembly and the air inlet connector, the air supply assembly inputs gas to the air vent block, mixing the gas with the powder and carrying away powder particles from the bristles. The mixed powder and gas are then blown out of the cavity. When the input gas enters the flat grinding brush module through the air supply assembly, because the flat grinding brush module and the covered motor module are connected by pipes, the gas simultaneously enters the motor housing from the air pipe connector, ensuring a consistent pressure difference between the flat grinding brush module and the covered motor module. This prevents the relative flow of dust and gas due to pressure differences from clogging the motor.

[0016] Furthermore, the feeding assembly includes a feeding cylinder, a feeding push rod, a feeding pressure block, and a sealing block. One end of the feeding push rod is fastened to the lead screw lifting module, and the other end of the feeding push rod is inserted into the feeding cylinder. The feeding cylinder and the feeding push rod are slidably connected. The feeding cylinder and the feeding pressure block are fastened together. The feeding cylinder passes through the feeding pressure block. The feeding cylinder and the base cover plate are connected by a pipe. The feeding pressure block and the base cover plate are fastened together. A sealing block is provided on the feeding push rod, and the sealing block is slidably connected to the feeding cylinder.

[0017] The lead screw lifting module controls the up-and-down movement of the feeding push rod by fixing it to the feeding cylinder and the feeding pressure block, as well as the feeding pressure block and the base cover plate. The rising feeding push rod feeds the base cover plate. Since there are two sets of feeding components, two sets of powder can be fed. The mixing ratio of the two powders can be determined by the ratio of the inner diameters of the two feeding cylinders. When the gas is mixed with the powder by the gas supply component, the concentration of the powder can be controlled by the lifting speed of the feeding push rod. The sealing block is made of elastic and wear-resistant silicone pad, fixed on the feeding push rod, and in close contact with the wall of the feeding cylinder to form a seal.

[0018] Furthermore, the feeding cylinder has a cavity inside, and a through hole is provided below the base cover plate. One end of the cavity is connected to the through hole pipe. The feeding push rod is inserted into the cavity, and the cavity is slidably connected to the feeding push rod and the sealing block respectively.

[0019] The raw material powder in the cavity of the feeding cylinder is lifted and sent to the through hole by the feeding pusher, and then reaches the bottom of the brush plate through the through hole. The brush plate and brush bristles rotate to break the powder into powder, and the powder is then mixed with the input gas and output.

[0020] Furthermore, the lead screw lifting module includes a lifting base, a lifting motor, a first roller, a second roller, a belt, a support frame, a lifting lead screw, a slider, and a slide rail. The support frame is fastened to the machine frame, the support frame is fastened to the lifting motor, the output end of the lifting motor is fastened to the first roller, the first roller is in frictional contact with the belt, the belt is in frictional contact with the second roller, the second roller is fastened to the lifting lead screw, the lifting lead screw is threaded to the slider, the slider is slidably connected to the slide rail, one end of the lifting base is fastened to the feeding push rod, and the other end of the lifting base passes through the machine frame and is fastened to the slider.

[0021] The screw lifting module is fixed to the machine body by the support frame and the frame. The lifting motor outputs torque to drive the first roller to rotate. The second roller also rotates due to the friction between the belt and the first roller and the second roller respectively. The second roller is fixed to the lifting screw and the lifting screw is connected to the slider. The slider moves up and down on the slide rail. The lifting base is fixed to the slider and the lifting base is fixed to the feeding push rod. When the slider rises, it provides the feeding power to the feeding push rod and controls the feeding speed, thereby controlling the concentration of the mixed gas.

[0022] Furthermore, the air supply assembly includes a flow meter, an air inlet pipe, a first branch pipe, and a second branch pipe. The air inlet pipe is fastened to the frame, and a flow meter is installed on the air inlet pipe. The air inlet pipe is connected to the first branch pipe and the second branch pipe respectively. The first branch pipe is connected to the air pipe connector pipe, and the second branch pipe is connected to the air inlet connector pipe.

[0023] The flow meter controls the flow rate of the gas entering the inlet pipe, and then the gas is delivered to the air pipe joint and the air inlet joint through the first branch pipe and the second branch pipe respectively. After the gas enters the air inlet joint, it mixes with the crushed powder and is then sprayed out through the nozzle. The gas entering the air pipe joint is connected to the connecting cylinder and the cavity cover plate to ensure consistent internal pressure, thus forming a stable flow.

[0024] Compared with the prior art, the beneficial effects of the present invention are: 1. It can simultaneously mix and feed two different powders. By controlling the inner diameter ratio of the two feeding cylinders, the ratio of the two powders can be controlled at the same lifting and feeding speed.

[0025] 2. Using a flat brush disc, the high-speed rotating crusher lifts the fed powder, reducing the impact of powder compression and agglomeration, and greatly improving the utilization rate of raw material powder;

[0026] 3. The lifting motor, lead screw and track are used to fix the material, which can improve the lifting and feeding speed, precisely control the amount of powder fed, and control the gas flow rate through the flow meter, so as to quantitatively control and calculate the concentration of the mixed gas.

[0027] 4. At the same time, the motor module chamber is connected to the input gas pipeline to ensure that the pressure difference between the motor module chamber and the flat brush module chamber is consistent, so that the relative flow of dust and gas due to pressure difference will not block the motor.

[0042] like Figure 2 As shown, the motor module 2 includes a motor housing 21, a high-speed motor 22, a connecting cylinder 23, a motor coupling 24, and an air pipe connector 25. The upper end of the motor housing 21 is fastened to the frame 11. The motor housing 21 and the air pipe connector 25 are connected by a pipe. The air pipe connector 25 is connected to the air supply component 6 by a pipe. The high-speed motor 22 is installed inside the motor housing 21. The motor housing 21 and the connecting cylinder 23 are fastened together. The output end of the high-speed motor 22 passes through the motor housing 21. The output end of the high-speed motor 22 is fastened to the motor coupling 24. The motor coupling 24 is placed inside the connecting cylinder 23.

[0043] The high-speed motor 22 is placed inside the motor housing 21. The output torque of the high-speed motor 22 drives the motor coupling 24 to rotate. The motor coupling 24 is protected by a connecting cylinder 23. The connecting cylinder 23 is placed between the motor housing 21 and the flat brush module 3. The motor housing 21 is fixed on the frame 11. The air pipe connector 25 below the motor housing 21 is connected to the air supply component 6, so the air supply component 6 supplies gas to the inside of the motor housing 21.

[0044] like Figure 2 As shown, the motor housing 21 includes an upper cover plate 211, a covering cylinder 212, a lower cover plate 213, and a sealing gasket 214. There are two sets of sealing gaskets 214, which are respectively fastened to the upper cover plate 211 and the lower cover plate 213. The covering cylinder 212 is placed between the two sets of sealing gaskets 214 and is fastened to the two sets of sealing gaskets 214. A high-speed motor 22 is provided on the lower cover plate 213. The output end of the high-speed motor 22 passes through the lower cover plate 213. The lower cover plate 213 is fastened to the connecting cylinder 23.

[0045] The motor housing 21 is composed of an upper cover plate 211, a sealing gasket 214, a covering cylinder 212, a sealing gasket 214, and a lower cover plate 213 from top to bottom. The two sets of sealing gaskets 214 improve the sealing between the covering cylinder 212 and the upper cover plate 211 and the lower cover plate 213, preventing the exchange of air with the outside.

Since there are two sets of feeding components 4, two sets of powder can be fed. The mixing ratio of the two powders can be determined by the ratio of the inner diameters of the two feeding cylinders 41. When the gas is mixed with the powder by the gas supply component 6, the concentration of the powder can be controlled by the lifting speed of the feeding push rod 42. The sealing block 44 is made of elastic and wear-resistant silicone pad, fixed on the feeding push rod 42, and in close contact with the tube wall of the feeding cylinder 41 to form a seal.

[0054] like Figure 7 As shown, the air supply assembly 6 includes a flow meter 61, an air inlet pipe 62, a first branch pipe 63, and a second branch pipe 64. The air inlet pipe 62 is fastened to the frame 11. The flow meter 61 is installed on the air inlet pipe 62. The air inlet pipe 62 is connected to the first branch pipe 63 and the second branch pipe 64 respectively. The first branch pipe 63 is connected to the air pipe connector 25, and the second branch pipe 64 is connected to the air inlet connector 39.

[0055] The flow meter 61 controls the flow rate of the gas entering the inlet pipe 62, and then the gas is delivered to the gas pipe joint 25 and the inlet joint 39 through the first branch pipe 63 and the second branch pipe 64 respectively. After the gas enters the inlet joint 39, it mixes with the crushed powder and is then sprayed out through the nozzle 36. The gas entering the gas pipe joint 25 is connected to the connecting cylinder 23 and the cavity cover plate 31 to ensure consistent internal pressure, thereby forming a stable flow.

[0056] Working principle of the invention:

[0057] The lifting base 51 moves up and down controlled by the lifting motor 52, providing power for the feeding push rod 42 and controlling the feeding speed, thereby controlling the concentration of the mixed gas. The raw material powder in the feeding cylinder 41 is fed to the part brush plate 35 and brush bristles 37 by the feeding push rod 42. The high-speed motor 22 controls the motor coupling 24 to rotate, which in turn drives the brush plate 35 and brush bristles 37 to rotate, crushing the raw material powder into powder. The flow meter 61 controls the input gas to enter the flat grinding brush module 3 through the air inlet connector 39. The powder mixes with the input gas and is output. Since the flat grinding brush module 3 and the covered motor module 2 are connected by pipelines, the gas simultaneously enters the motor housing 21 from the air pipe connector 25, ensuring that the pressure difference inside the flat grinding brush module 3 and the covered motor module 2 is consistent, and the relative flow of dust and gas due to the pressure difference will not block the motor.
