Description

Technical Field

[0001] This invention relates to the field of flame retardant production equipment technology, and in particular to an automated proportioning and mixing device for brominated epoxy flame retardants. Background Technology

[0002] Brominated epoxy flame retardants are highly efficient and environmentally friendly bromine-containing flame retardant materials with advantages such as high flame retardant efficiency, good thermal stability, and excellent compatibility. They are widely used in plastics, rubber, coatings, electronic packaging materials, and other fields. In the production process of brominated epoxy flame retardants, the precise ratio and uniform mixing of solid and liquid raw materials are the core processes that determine the flame retardant performance and stability of the product, directly affecting the bromine content, dispersion uniformity, and storage stability of the finished product.

[0003] Based on the above, traditional brominated epoxy flame retardant mixing equipment relies heavily on manual labor for raw material weighing and proportioning, resulting in extremely low automation levels. Manual operation is affected by subjective judgment, operator skill, and human negligence, making it difficult to guarantee weighing accuracy. This easily leads to imbalances in the ratio of solid powder to liquid raw materials, directly causing the finished product to fail to meet flame retardant performance standards and inconsistent product quality across batches, significantly reducing the product qualification rate. At the same time, the entire process of manual proportioning requires a large investment of manpower and resources, which is not only labor-intensive and inefficient but also significantly increases the company's production labor costs, hindering the large-scale, standardized, and stable production of flame retardants. Summary of the Invention

[0004] In view of this, the present invention provides an automated mixing device for brominated epoxy flame retardants. Through the setting of a quantitative component, a first motor, in conjunction with a lead screw drive, drives the transfer cylinder to move laterally, automatically completing quantitative feeding and precise dispensing. Combined with a flow meter to monitor the liquid feed flow rate in real time, it can accurately control the solid-liquid ratio of the brominated epoxy flame retardant raw materials, effectively replacing manual mixing operations, avoiding mixing errors caused by manual operation, ensuring consistent mixing parameters for each batch of products, and improving product quality and stability from the source. Through the setting of the mixing component, a second motor drives a third bevel gear to rotate, simultaneously driving the first and second bevel gears to rotate in opposite directions, thereby driving the third... The first and second stirring rods rotate in opposite directions, creating a multi-directional shearing force that accelerates the fusion of brominated epoxy solid and liquid materials, resulting in a more uniform distribution of material composition and concentration, and effectively improving the quality of the finished flame retardant. Through the design of the bonding components, the stirring components synchronously drive the cleaning scraper to rotate, allowing it to scrape away highly viscous brominated epoxy materials adhering to the inner wall of the tank in real time. This prevents material adhesion, accumulation, solidification, and deterioration, maintaining the cleanliness of the tank. Simultaneously, the clamping spring provides continuous elastic clamping force, automatically compensating for the distance between the scraper and the inner wall of the mixing tank, ensuring the cleaning scraper remains tightly fitted to the tank wall and guarantees stable operation.

[0008] Furthermore, a retaining sleeve is rotatably mounted on the outer side of the drive shaft, and a second bevel gear is fixedly connected to the top outer side of the retaining sleeve.

[0010] Furthermore, a connecting top frame is fixedly connected to the top of the mixing tank, a second motor is fixedly installed on one side of the connecting top frame, and a third bevel gear is fixedly connected to the drive end of the second motor. The third bevel gear meshes with the first bevel gear and the second bevel gear respectively.

[0011] Furthermore, the side of the arc-shaped frame is provided with a bonding component, which includes a movable sliding hole, a pressing groove and a tightening spring. The arc-shaped frame is provided with a movable sliding hole, and the inside of the second stirring rod is provided with a pressing groove, in which a tightening spring is provided.

[0012] Furthermore, the side of the arc-shaped frame is provided with a cleaning scraper. One side of the cleaning scraper is in contact with the inner wall of the mixing tank.

[0013] The automated mixing device for brominated epoxy flame retardants provided by this invention has the following beneficial effects.

[0014] By setting up the mixing components, the second motor drives the third bevel gear to rotate, which in turn drives the first and second bevel gears to rotate in opposite directions. This, in turn, drives the first and second stirring rods to rotate in opposite directions, so that the two sets of stirring rods form an all-round, multi-directional shearing force, which accelerates the fusion speed of brominated epoxy solid-liquid materials, makes the material composition and concentration distribution more uniform, and effectively improves the quality of the finished flame retardant.

[0015] By setting up the bonding components, the cleaning scraper is rotated synchronously by the stirring components, which can scrape off the highly viscous brominated epoxy material adhering to the inner wall of the tank in real time, avoiding material adhesion, accumulation, solidification and deterioration, and maintaining the cleanliness of the production inside the tank. At the same time, the clamping spring provides a continuous elastic clamping force, which can automatically compensate for the distance between the scraper wear and the inner wall of the mixing tank, so that the cleaning scraper is always in close contact with the inner wall of the mixing tank and can ensure stable operation of the cleaning scraper.

[0019] Example 1: Please refer to Figures 1 to 8 : This invention proposes an automated mixing device for brominated epoxy flame retardants, comprising: a mixing tank 1 and a metering component 2; The mixing tank 1 is fixedly connected to the top of a solid feed inlet 101, and a liquid feed inlet 1011 is provided on one side of the top of the mixing tank 1. The bottom of the mixing tank 1 is fixedly connected to a discharge port 102, and a control valve 1021 is installed on the discharge port 102. The mixing tank 1 is provided with a metering component 2, which includes the following components: Fixed carrier 201: Fixedly connected to one side of mixing tank 1, the top of fixed carrier 201 is fixedly connected to connecting bracket 2011, the bottom of connecting bracket 2011 is fixedly connected to connecting bottom frame 2012, and a reinforcing corner block 2013 is fixedly connected between connecting bottom frame 2012 and connecting bracket 2011. Guide rod 202: It is fixedly connected to the inside of the connecting base frame 2012. A lead screw 2021 is provided on the opposite side of the guide rod 202. One end of the lead screw 2021 passes through the connecting base frame 2012 and is fixedly connected to the driven pulley 2022 on the outside. 204: Located on the top of the connecting bracket 2011, the connecting base frame 2012 has a movable carrier plate 2041 inside, and a fixed vertical plate 2042 is fixedly connected to the bottom of the movable carrier plate 2041. The fixed vertical plate 2042 is provided with threaded holes 2043 and guide sliding holes 2044 respectively. Transfer cylinder 205: It is fixedly connected to the movable carrier plate 2041. A hinge shaft 2051 is provided on one side of the bottom of the transfer cylinder 205. A cover 2052 is provided at the bottom of the transfer cylinder 205. The cover 2052 is hinged to the hinge shaft 2051 through a hinge ear 2053. Valve body 206: Located on one side of liquid inlet 1011, valve body 206 is equipped with electric actuator 2061, and flow meter 2062 is provided on one side of electric actuator 2061.

[0020] The hybrid component connecting bracket 2011 has an assembly carrier plate 203 on one side. The bottom of the assembly carrier plate 203 is fixedly connected to a support block 2031. The top of the assembly carrier plate 203 is fixedly installed with a first motor 2032. The drive end of the first motor 2032 is fixedly connected to a drive pulley 2033. The drive pulley 2033 is rotatably connected to the driven pulley 2022 through a transmission belt 2034.

[0021] Workers pre-load brominated epoxy solid powder into the silo 204, then connect the required liquid raw materials to the front end of the liquid inlet 1011. Next, the first motor 2032 is started, driving the drive pulley 2033 to rotate. The drive pulley 2033, via the transmission belt 2034, drives the driven pulley 2022 and the lead screw 2021 to rotate synchronously. The lead screw 2021 engages with the threaded hole 2043 of the fixed vertical plate 2042, and is guided by the guide rod 202 and the guide slide hole 2044, causing it to drive the moving carrier plate 2041 to move smoothly laterally along the connecting bottom frame 2012. This, in turn, causes the transfer cylinder 205 to precisely move to the bottom of the silo 204, thus discharging the material. When the transfer cylinder 205 is full, an internal sensor detects a signal, which is transmitted to the control terminal. The control unit controls the first motor 2032 to rotate in the reverse direction, which in turn drives the lead screw 2021 to rotate in the reverse direction. The lead screw 2021 then drives the fixed vertical plate 2042 to move away from the hopper 204. While moving, the moving carrier plate 2041 automatically seals the outlet of the hopper 204. When it moves to a certain position, the cover 2052 loses its limit, and the material falls freely, thus entering the mixing tank 1 through the solid feed inlet 101. The liquid is pumped to the valve body 206 by a pump (which is existing technology and therefore not shown in the figure). The electric actuator 2061 is controlled to open the valve body 206, and the liquid raw material enters the mixing tank 1 through the liquid feed inlet 1011. The flow meter 2062 monitors the liquid flow rate in real time to achieve automated and precise mixing of solid and liquid raw materials.

[0022] Example 2: Based on Example 1, wherein, as Figure 5 and Figure 6 As shown, the mixing component mixing tank 1 is equipped with a mixing component 3 inside. The mixing component 3 includes a drive shaft 301, a first stirring rod 3011 and a first bevel gear 3012. The drive shaft 301 is rotatably installed in the middle of the mixing component mixing tank 1. The first stirring rod 3011 is fixedly connected to the outside of the drive shaft 301, and the first bevel gear 3012 is fixedly connected to the top of the drive shaft 301.

[0023] A locking bushing 302 is rotatably mounted on the outer side of the hybrid component drive shaft 301, and a second bevel gear 3021 is fixedly connected to the top outer side of the locking bushing 302.

[0024] The two sides of the mixing component rotating sleeve 302 are fixedly connected with fixed inclined rods 3022, the ends of the fixed inclined rods 3022 are fixedly connected with arc-shaped frame 3023, and the inner side of the arc-shaped frame 3023 is fixedly connected with a second stirring rod 3024. The second stirring rod 3024 and the first stirring rod 3011 are in a staggered structure.

[0025] A connecting top frame 303 is fixedly connected to the top of the mixing tank 1 of the mixing component. A second motor 3031 is fixedly installed on one side of the connecting top frame 303. A third bevel gear 3032 is fixedly connected to the drive end of the second motor 3031. The third bevel gear 3032 meshes with the first bevel gear 3012 and the second bevel gear 3021 respectively.

[0026] By starting the second motor 3031, the third bevel gear 3032 is driven to rotate. The third bevel gear 3032 simultaneously meshes with the first bevel gear 3012 and the second bevel gear 3021, causing the first bevel gear 3012 to drive the drive shaft 301 to rotate in the forward direction. The drive shaft 301 then drives the multiple sets of first stirring rods 3011 on the outer side to rotate synchronously. Meanwhile, the second bevel gear 3021 drives the retaining sleeve 302 to rotate in the reverse direction. The retaining sleeve 302, through the fixed inclined rod 3022, drives the arc-shaped frame 3023 to revolve around the drive shaft 301 in the reverse direction. The second stirring rod 3024 on the inner side of the arc-shaped frame 3023 rotates with it, thereby forming a bidirectional shearing force on the material, which makes the brominated epoxy solid and liquid materials quickly blend and homogenize, greatly improving the mixing uniformity.

[0027] Example 3: Based on Examples 1 and 2, wherein, as shown in Example 3... Figure 7 and Figure 8 As shown, the side of the arc-shaped frame 3023 of the mixing component is provided with a bonding component 4. The bonding component 4 includes a movable sliding hole 401, a pressing groove 4011 and a top-pressing spring 4012. The arc-shaped frame 3023 of the mixing component is provided with a movable sliding hole 401. The second stirring rod 3024 is provided with a pressing groove 4011 inside. The pressing groove 4011 is provided with a top-pressing spring 4012.

[0028] The side of the arc-shaped frame 3023 of the mixing component is provided with a cleaning scraper 402. One side of the cleaning scraper 402 is in contact with the inner wall of the mixing tank 1. A connecting support rod 4021 is fixedly connected to the side of the cleaning scraper 402 near the arc-shaped frame 3023. The connecting support rod 4021 passes through the movable sliding hole 401 and is fixedly connected to the extrusion cam 4022 in the extrusion groove 4011. The outer wall of the extrusion cam 4022 is in contact with the inner wall of the extrusion groove 4011.

[0029] As the arc-shaped frame 3023 rotates with the rotating sleeve 302, it drives the outer cleaning scraper 402 to always slide and scrape the material against the inner wall of the mixing tank 1, thus removing the material adhering to the inner wall. At the same time, when the cleaning scraper 402 can no longer adhere to the inner wall of the mixing tank 1 due to wear, the elastic clamping force of the top spring 4012 ensures that the cleaning scraper 402 always adaptively adheres to the inner wall of the tank, automatically compensating for assembly gaps and stirring vibration deviations, and continuously scraping away the sticky brominated epoxy material adhering to the inner wall of the mixing tank 1.

[0030] The specific usage and function of this embodiment are as follows: In this invention, the operator first puts the brominated epoxy solid powder into the silo 204, and then connects the required liquid raw materials to the front end of the liquid inlet 1011. Next, the first motor 2032 is started to drive the drive pulley 2033 to rotate. The drive pulley 2033 drives the driven pulley 2022 and the lead screw 2021 to rotate synchronously through the transmission belt 2034. The lead screw 2021 rotates and engages with the threaded hole 2043 of the fixed vertical plate 2042, and is limited and guided by the guide rod 202 and the guide sliding hole 2044, so that it drives the moving carrier plate 2041 to move smoothly laterally along the connecting bottom frame 2012. This causes the transfer cylinder 205 to precisely shift to the bottom of the hopper 204, allowing material to fall. When the transfer cylinder 205 is full, an internal sensor detects a signal and transmits it to the control terminal. The control terminal then controls the first motor 2032 to rotate in the reverse direction, which in turn drives the lead screw 2021 to rotate in the reverse direction. The lead screw 2021 then drives the fixed vertical plate 2042 to move away from the hopper 204. Simultaneously, the moving carrier plate 2041 automatically seals the outlet of the hopper 204. When the material reaches a certain position, the cover 2052 loses its limit, allowing the material to fall freely and enter the mixing tank 1 through the solid feed inlet 101. The liquid is then pumped... (This is existing technology and therefore not shown in the figure) The liquid raw material is transported to valve body 206. The valve body 206 is opened by controlling electric actuator 2061, and the liquid raw material enters mixing tank 1 through liquid inlet 1011. The liquid flow rate is monitored in real time by flow meter 2062 to achieve automated and precise mixing of solid and liquid raw materials, effectively replacing manual mixing operations, avoiding mixing errors caused by manual operation, ensuring uniform mixing parameters for each batch of products, and improving product quality and stability from the source. Then, the second motor 3031 is started to drive the third bevel gear 3032 to rotate. The third bevel gear 3032 simultaneously meshes with the first bevel gear 3012 and the second bevel gear 3021. The first bevel gear 3012 drives the drive shaft 301 to rotate in the forward direction, and the drive shaft 301 drives the multiple sets of first stirring rods 3011 on the outside to rotate synchronously. Meanwhile, the second bevel gear 3021 drives the retaining sleeve 302 to rotate in the reverse direction. The retaining sleeve 302 drives the arc-shaped frame 3023 to revolve around the drive shaft 301 in the reverse direction through the fixed inclined rod 3022. The second stirring rod 3024 on the inner side of the arc-shaped frame 3023 rotates with it, thereby forming a bidirectional shearing force on the material, which makes the brominated epoxy solid and liquid materials quickly blend and homogenize, greatly improving the mixing uniformity. Finally, by opening the control valve 1021, the mixed material is discharged from the discharge port 102.
