Description

Technical Field

[0001] This utility model relates to a feeding device for 5-acetylacetaminobenzimidazole, belonging to the technical field of feeding equipment. Background Technology

[0002] 5-Acetylacetaminobenzimidazole is commonly used in the synthesis of pharmaceuticals, pesticides, pigments, and specialty materials, and is also used as a pigment intermediate in petrochemicals. Activated carbon is required in the production of 5-acetylacetaminobenzimidazole, and a feeding device is needed to add the activated carbon. Current feeding devices feed the activated carbon into the reaction tank through a feeding port. When the activated carbon particles enter the reaction tank, they tend to concentrate in a fixed area, which is not conducive to mixing with other materials, affecting the production efficiency of 5-acetylacetaminobenzimidazole. Furthermore, the activated carbon particles sometimes clump together, which is also detrimental to their usability if directly added to the reaction tank. Utility Model Content

[0003] This invention provides a 5-acetylacetaminobenzimidazole feeding device, which solves the problem that in current devices, activated carbon particles tend to concentrate in a fixed area when entering the reaction tank, which is not conducive to mixing activated carbon particles with other materials and prevents the activated carbon particles from clumping together, thus affecting production efficiency.

[0004] This utility model relates to a feeding device for 5-acetylacetamidobenzimidazole, comprising a reaction tank, a stirring shaft inside the reaction tank, a stirrer fixed on the stirring shaft, and a stirring motor fixed on the top of the stirring shaft. The device is characterized by: a feeding hopper fixed on the top of the reaction tank, feed pipes at both the front and rear of the top of the feeding hopper, a feed pipe fixed at the bottom of the feeding hopper, a distribution cone fixed on the upper part of the stirring shaft, the bottom outlet of the feed pipe facing the top of the distribution cone, a screen fixed inside the feeding hopper, a crushing rod above the screen, a crushing shaft rotatably mounted on the feeding hopper fixedly connected to the crushing rod, a driven pulley fixedly fixed at the top of the crushing shaft passing through the feeding hopper, a driving pulley connected to the driven pulley via a belt, and the driving pulley fixed on the stirring shaft.

[0005] As a preferred option, multiple material-distributing plates are evenly fixed on the top of the material-distributing cone, which can better distribute the material.

[0006] As a preferred embodiment, a bag-breaking box is fixed to the top of the feed pipe. Multiple support rods are fixed horizontally inside the bag-breaking box. The top of the bag-breaking box has a bag-dispensing opening, and a box cover is provided to close the bag-dispensing opening. A pair of sprockets are provided on the lower front and rear sides of each support rod. A rotating shaft is fixedly connected between the pair of sprockets on the same side. Corresponding sprockets on the front and rear sides are connected by chains. Support plates are fixed on the chains on the left and right sides. Multiple blades are fixed on the top of the support plates. The top of the blades is above the top of the support rods. By rotating the rotating shaft, the sprockets and chains are rotated, thereby moving the blades to cut the material bags placed on the support rods for sealed feeding.

[0007] As a preferred embodiment, one end of one of the rotating shafts extends out of the bag-breaking box and is fixed with a rocker arm to facilitate the rotation of the rotating shaft.

[0008] As a preferred embodiment, the top of the front and rear ends of the middle support rod is fixed with piercing nails. When the material bag is placed on the support rod, the piercing nails can pierce the material bag, hook the material bag, and prevent the material bag from falling down after feeding.

[0009] As a preferred embodiment, the bottom outer side of the lid is provided with a limiting flange, which is fastened to the top outer side wall of the bag-breaking box.

[0010] This utility model has the following beneficial effects:

[0011] By installing a screen in the feeding hopper and a crushing rod above the screen, the material that has become lumpy and enters the feeding hopper can be crushed by the crushing rod. The crushing shaft is driven to rotate by the stirring shaft, eliminating the need for a separate power component and reducing costs. In addition, the material entering the reaction tank through the feeding pipe will flow onto the distribution cone, and then be distributed by the rotation of the distribution cone, resulting in a more uniform material distribution and ensuring the production efficiency of 5-acetylacetaminobenzimidazole.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example 1, as Figures 1 to 5 As shown, this utility model is a feeding device for 5-acetylacetamidobenzimidazole, including a reaction tank 1, a stirring shaft 2 inside the reaction tank 1, a stirrer 3 fixed on the stirring shaft 2, a stirring motor 11 fixed on the top of the stirring shaft 2, a feeding bin 7 fixed on the top of the reaction tank 1, feeding pipes 10 at the front and rear of the top of the feeding bin 7, a feeding pipe 6 fixed at the bottom of the feeding bin 7, a distribution cone 4 fixed on the upper part of the stirring shaft 2, the bottom outlet of the feeding pipe 6 facing the top of the distribution cone 4, a screen 8 fixed inside the feeding bin 7, a crushing rod 9 above the screen 8, a crushing shaft 14 fixedly connected to the crushing rod 9 and rotatably mounted on the feeding bin 7, a driven pulley 15 fixedly fixed through the top of the crushing shaft 14 through the feeding bin 7, a driving pulley 12 connected to the driven pulley 15 through a belt 13, and the driving pulley 12 fixed on the stirring shaft 2.

[0020] In use, the stirring motor 11 is started, which drives the stirring shaft 2 to rotate, thereby driving the agitator 3 to stir. It also drives the crushing shaft 14 to rotate through the driving pulley 12, belt 13 and driven pulley 15. The activated carbon granules enter the feeding bin 7 from the feed pipe 10. When they fall onto the screen 8, the un-clumped activated carbon granules pass through the screen 8 and fall into the feeding pipe 6. The clumped material is blocked by the screen 8 and then crushed by the crushing rod 9. The material entering the feeding pipe 6 is conveyed to the top of the distribution cone 4 and then thrown to the sides by the rotating distribution cone 4 to distribute the material. The activated carbon granules are then evenly distributed in the reaction tank 1 and quickly mixed with other materials under the stirring of the agitator 3.

[0021] Example 2: Based on Example 1, multiple material feeding plates 5 are evenly fixed on the top of the material feeding cone 4.

[0022] A bag-breaking box 23 is fixed to the top of the feed pipe 10. Multiple support rods 21 are fixed horizontally inside the bag-breaking box 23. A bag-dispensing opening is located at the top of the bag-breaking box 23, and a box cover 20 is provided to close the bag-dispensing opening. A pair of sprockets 22 are located on the lower front and rear sides of each support rod 21. A rotating shaft 16 is fixedly connected between the pair of sprockets 22 on the same side. Corresponding sprockets 22 on the front and rear sides are connected by chains. Support plates 17 are fixed to the chains on both sides. Multiple blades 18 are fixed to the top of the support plates 17, with the tops of the blades 18 positioned above the tops of the support rods 21. A heating jacket is provided outside the reaction vessel 1, connected to a heating agent inlet pipe and a heating agent outlet pipe. A temperature sensor is located inside the reaction vessel 1. A discharge pipe with a valve is located at the bottom of the reaction vessel 1.

[0023] One end of one of the rotating shafts 16 extends out of the bag box 23 and is fixed with a rocker arm 24.

[0024] Piercing nails 19 are fixed to the top of the front and rear ends of the middle support rod 21.

[0025] The bottom outer side of the lid 20 is provided with a limiting flange, which is fastened to the top outer side wall of the bag-breaking box 23.

[0026] Before feeding, remove the box cover 20, then place the activated carbon granule material bag from the bag opening onto the support rod 21, with the piercing nails 19 on both sides penetrating both ends of the activated carbon granule material bag. Then, close the box cover 20, and rotate the rocker arm 24, thereby driving the rotating shaft 16 to rotate. Through the sprocket 22 and chain, the blade 18 on the support plate 17 cuts open the bottom of the activated carbon granule material bag, thus sealing the bag for feeding and preventing dust. After feeding for a period of time, the box cover 20 can be opened to remove the damaged activated carbon granule material bag.
