Description

Technical Field

[0001] This utility model relates to the field of flame retardant production technology, and more specifically, to a vibrating hopper for a flame retardant feeding machine. Background Technology

[0002] Flame retardants are chemical additives used to improve the combustion performance of combustible materials, enhancing their safety by preventing, delaying, or terminating flame propagation. They are widely used in construction, textiles, electronics, and transportation, primarily working through physical or chemical means to reduce fire risk during combustion. The transportation of raw materials (such as flame retardant powders and granules) is a fundamental step in the production of flame retardants or flame-retardant materials.

[0003] The height of existing vibrating unloading hoppers is generally fixed. When vehicles of different heights drive under the vibrating unloading hopper to catch the material falling from the hopper, the vibrating unloading hopper cannot meet the needs of vehicles of different heights well, making it very inconvenient to use. At the same time, because the width distance between the two legs of the fixed frame is not very large, it is difficult for vehicles to drive between the two legs of the fixed frame. The vehicles are very likely to hit the fixed frame, causing damage to the fixed frame and affecting the use of the vibrating unloading hopper.

[0004] A search revealed that Chinese patent CN208439729U discloses a built-in vibrating unloading hopper. The vibrating unloading hopper includes a hopper, a vibrating motor, a hopper fixing frame, and a support. The hopper fixing frame and the support are vertically connected, and the overall height of the vibrating unloading hopper is adjustable. It can adapt to vehicles and other tools of different heights for receiving goods, and has a wide range of applications and is easy to use.

[0005] In actual use, the flame retardant powder in the above-mentioned built-in vibrating unloading hopper is prone to static electricity due to friction, collision or separation during production, conveying or stacking. Static electricity accumulation may cause the powder to be adsorbed on the hopper wall or equipment, resulting in production interruption or unstable material flow, thereby affecting production efficiency and product quality. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a vibrating hopper for a flame retardant feeder to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The vibrating hopper of the flame retardant feeder includes a support frame, an auger conveyor installed inside the support frame, a hopper connected to the top of the auger conveyor, and an anti-static component and a vibration mechanism installed inside the hopper.

[0009] The static eliminator includes a first hopper, which is fixedly connected to the interior of the hopper. A vibrating box is installed inside the hopper. Two fixed outer shells are fixedly connected inside the vibrating box. A guide cone is fixedly connected to the top of the vibrating box. A dual-axis motor is installed inside one of the fixed outer shells. Threaded rods are fixedly connected to both output ends of the dual-axis motor. A threaded ring is threaded to the outer side of the threaded rod. A metal sweeping rod is fixedly connected to one side of the threaded ring. Multiple static elimination brushes are fixedly connected inside the metal sweeping rod. A slip ring is fixedly connected to one side of the metal sweeping rod. A guide rod is slidably connected inside the slip ring. The guide rod is fixedly connected to the interior of the other fixed outer shell.

[0010] By adopting the above technical solution, the sweeping action of the metal sweeping rod can bring the powder surface into contact, effectively neutralizing or dispersing static charge and ensuring electrostatic safety during the production process.

[0011] As a further description of the above technical solution: the vibration mechanism includes a filter screen, which is fixedly connected to the inside of the vibration box. Two feeding ramps are fixedly connected inside the vibration box. Two second feeding hoppers are connected to the bottom of the vibration box. A connecting shell is fixedly connected to the bottom of the vibration box. A vibration motor is installed inside the connecting shell and is fixedly connected to the bottom of the vibration box. Two limiting posts are fixedly connected to the bottom of the vibration box. Limiting sleeves are slidably connected to the outside of the limiting posts and are fixedly connected to the inside of the hoppers. Multiple springs are fixedly connected to the bottom of the vibration box. A fixing plate is fixedly connected to the bottom of each spring and is fixedly connected to the inside of the hoppers.

[0012] By adopting the above technical solution, the vibration of the connecting box can effectively break up powder bridging and prevent agglomeration and blockage.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up an antistatic component, compared with the existing technology, the reciprocating sweeping of two metal sweeping rods can use their conductivity to conduct away the static electricity generated on the powder surface in time. Multiple static elimination brushes can increase the contact area with the powder, effectively neutralize or conduct away the static charge, and the reciprocating sweeping can further loosen the combustion aid powder, reduce the accumulation and blockage of powder in the hopper, and ensure smooth material flow.

[0015] 2. By setting up a vibration mechanism, compared with the existing technology, the two limiting columns can provide guidance for the vibration of the vibration box, which can destroy the static friction between the combustion aid powder, reduce the formation of arched structures or adhesion of powder to the wall in the hopper, and effectively break powder bridging, reduce agglomeration and blockage, which is conducive to improving conveying efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The embodiments disclosed in this application are as follows: Figure 1-6 The vibrating hopper of the flame retardant feeder shown includes a support frame 1, an auger conveyor 2 installed inside the support frame 1, a hopper 3 connected to the top of the auger conveyor 2, and an anti-static component and a vibration mechanism installed inside the hopper 3.

[0025] The antistatic assembly includes a first hopper 4, which is fixedly connected to the inside of a hopper 3. A vibrating box 5 is installed inside the hopper 3. Two fixed housings 6 are fixedly connected inside the vibrating box 5. A guide cone 7 is fixedly connected to the top of the vibrating box 5. A dual-axis motor 8 is installed inside one of the fixed housings 6. Threaded rods 9 are fixedly connected to both output ends of the dual-axis motor 8. A threaded ring 10 is threadedly connected to the outer side of the threaded rod 9. A metal sweeping rod 11 is fixedly connected to one side of the threaded ring 10. Multiple static elimination brushes 14 are fixedly connected inside the metal sweeping rod 11. A slip ring 12 is fixedly connected to one side of the metal sweeping rod 11. A guide is slidably connected inside the slip ring 12. The guide rod 13 is fixedly connected to another fixed housing 6. The two output ends of the dual-axis motor 8 drive the threaded rod 9 to rotate, so that the threaded rod 9 can drive the threaded ring 10 to move through the thread, so that the threaded ring 10 can drive the metal sweeping rod 11 to move. The guide rod 13 can provide guidance for the movement of the metal sweeping rod 11. The wavy surfaces on both sides of the metal sweeping rod 11 cooperate with multiple static elimination brushes 14 to contact the surface of the combustion aid powder. The conductivity of the brushes can conduct away the static electricity generated on the powder surface in time, thereby reducing the static electricity inside the combustion aid powder and reducing the accumulation and blockage of powder in the hopper.

[0026] Reference Figure 3 and 4 As shown, the vibration mechanism includes a filter screen 15, which is fixedly connected to the inside of the vibration box 5. Two feeding ramps 16 are fixedly connected inside the vibration box 5. Two second feeding hoppers 17 are connected to the bottom of the vibration box 5. A connecting shell 18 is fixedly connected to the bottom of the vibration box 5, and a vibration motor 19 is installed inside the connecting shell 18. The vibration motor 19 is fixedly connected to the bottom of the vibration box 5. Two limiting posts 20 are fixedly connected to the bottom of the vibration box 5. Limiting sleeves 21 are slidably connected to the outer sides of the limiting posts 20, and the limiting sleeves 21 are fixedly connected to the inside of the hoppers 3. Multiple springs 22 are fixedly connected to the bottom of the box 5. A fixing plate 23 is fixedly connected to the bottom of the springs 22. The fixing plate 23 is fixedly connected to the inside of the hopper 3. Under the action of the vibration motor 19, the vibration box 5 can be driven to vibrate. The extension and contraction of the multiple springs 22 can assist the vibration box 5 to vibrate. The limiting post 20 is slidably connected to the inner side of the limiting sleeve 21, which can provide guidance for the vibration of the vibration box 5. Thus, the vibration box 5 can destroy the static friction between the combustion aid powder through vibration, reducing the formation of an arched structure or adhesion of the powder to the wall in the hopper.

[0027] Working principle of this utility model: This utility model designs a vibrating hopper for a flame retardant feeding machine, the specific structure of which is shown in the attached instruction manual. Figure 1-6As shown, in this technical solution, through the cooperation of various structures, when it is necessary to convey the combustion accelerator powder, the combustion accelerator is first placed inside the hopper 3, and then the vibration motor 19 is started. Under the action of the vibration motor 19, the vibration box 5 can be driven to vibrate. The extension and contraction of multiple springs 22 can assist the vibration box 5 in vibrating. The limiting post 20 is slidably connected to the inner side of the limiting sleeve 21, which can provide guidance for the vibration of the vibration box 5, so that the vibration box 5 can vibrate stably. Thus, the combustion accelerator powder can be screened through the filter screen 15. The guide cone 7 can disperse the falling combustion accelerator powder into two parts. While the vibration box 5 is vibrating, the dual-axis motor 8 is started. The two output ends of the dual-axis motor 8 drive the threaded rod 9 to rotate. The threaded rod 9 can rotate through the thread. The threaded ring 10 is driven to reciprocate. The inner side of the slip ring 12 is slidably connected to the guide rod 13, so that the metal sweeping rod 11 can be stably swept above the filter screen 15 to sweep the combustion-supporting powder. The wavy surface on both sides of the metal sweeping rod 11 can increase the contact area with the combustion-supporting powder and drive multiple static elimination brushes 14 to contact the combustion-supporting powder to reduce the static electricity of the combustion-supporting powder. At the same time, the two metal sweeping rods 11 continuously sweep above the filter screen 15, so that the vibration box 5 can screen the combustion-supporting powder when vibrating, so that the powder can quickly pass through the filter screen 15. The filtered powder can be transported into the auger conveyor 2 through the two second discharge hoppers 17. Then, the auger conveyor 2 is started to complete the feeding of the combustion-supporting powder.
