Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a feeding device for fumed silica. Background Technology

[0002] Fumed silica is one of the most important high-tech ultrafine inorganic new materials. Due to its small particle size, it has a large specific surface area, strong surface adsorption force, large surface energy, high chemical purity, good dispersion performance, and unique properties in terms of thermal resistance and electrical resistance.

[0003] To reduce dust pollution from precipitated silica and improve its flowability and storage, precipitated silica is granulated using a granulator. However, when feeding precipitated silica, the packaging bag is usually opened and the material is poured out. Because the particle size of precipitated silica is very small, it tends to disperse easily like flour during the pouring process, causing dust pollution. If the dispersed precipitated silica is inhaled, it can be harmful to the human body. Therefore, a feeding device for fumed silica is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, fumed silica tends to disperse easily like flour during the pouring process, causing dust pollution. The dispersed fumed silica can be inhaled and cause harm to the human body. Therefore, this invention proposes a fumed silica feeding device.

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

[0006] A feeding device for fumed silica includes a bag-removing box with a sealing cover hinged to its top. The outer and inner walls of the bag-removing box near the bottom are provided with grooves. A cutting assembly is provided inside the grooves. An outer shell is fixedly connected to the opening at the bottom of the bag-removing box. A conveying roller is rotatably mounted inside the outer shell. A metering groove is provided on the surface of the conveying roller. A rotating handle is fixedly connected to the center of the conveying roller. The rotating handle is rotatably connected to the side wall of the outer shell. A discharge pipe is fixedly connected to the discharge port at the bottom of the outer shell.

[0007] Preferably, the contact surface between the sealing cap and the top of the unpacking box is provided with a magnetic rubber sticker, and a powder pump is installed on the side wall of the unpacking box, with one end of the powder pump connected to the unpacking box through an air extraction pipe.

[0008] Preferably, the other end of the powder pump is fixedly connected to an exhaust pipe, the exhaust pipe is equipped with a one-way valve, and one end of the exhaust pipe is threadedly connected to a filter bag through a threaded joint.

[0009] Preferably, a clamping screw is rotatably provided on one side wall of the bag-unpacking box opposite to the cutting component, and one end of the clamping screw is rotatably connected to a push plate.

[0010] Preferably, the cutting assembly includes an inner magnetic block and an outer magnetic block that are slidably connected to the inside of the groove, respectively. A blade is fixedly connected to the surface of the inner magnetic block, and the inner magnetic block and the outer magnetic block are magnetically attracted to each other.

[0011] Preferably, the outer wall of the bag-removing box is rotatably provided with a drive screw at the slide groove, and the surface of the drive screw is threadedly connected with a nut block that is fixedly connected to the outer magnetic block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-6 A feeding device for fumed silica includes a bag-removing box 1, a sealing cover 2 hinged to the top of the bag-removing box 1, and a magnetic rubber sticker on the contact surface between the sealing cover 2 and the top of the bag-removing box 1.

[0025] It should be noted that the magnetic rubber sticker can enhance the seal between the sealing cap 2 and the top of the unpacking box 1, preventing the leakage of white carbon black diffused inside the unpacking box 1.

[0026] The outer and inner walls of the bag-removing box 1 are provided with grooves 101 near the bottom. A cutting assembly is provided inside the groove 101. The cutting assembly includes an inner magnetic block 13 and an outer magnetic block 15 that are slidably connected inside the groove 101. A blade 14 is fixedly connected to the surface of the inner magnetic block 13. The inner magnetic block 13 and the outer magnetic block 15 are magnetically attracted to each other. Furthermore, a drive screw 3 is rotatably provided on the outer wall of the bag-removing box 1 at the groove 101. A nut block 4 that is fixedly connected to the outer magnetic block 15 is threadedly connected to the surface of the drive screw 3.

[0027] It should be noted that when the white carbon black is placed inside the unpacking box 1, the nut block 4 on the surface of the drive screw 3 is moved along the drive screw 3 by rotating the drive screw 3, which in turn drives the outer magnetic block 15 connected to the nut block 4 to move. The outer magnet drives the inner magnet to move through magnetic attraction, and the inner magnet drives the blade 14 to move, which can cut open the packaging bag containing white carbon black, so that the white carbon black inside the packaging bag is automatically poured into the unpacking box 1.

[0028] The advantage of taking the above operation is that opening the white carbon black packaging bag inside the unpacking box 1 can prevent the white carbon black that is dispersed during the unpacking process from leaking into the external environment and causing dust pollution.

[0029] The bottom opening of the bag-removing box 1 is fixedly connected to the outer shell 5. The inner side of the outer shell 5 is rotatably equipped with a conveying roller 12. The surface of the conveying roller 12 is provided with a metering groove 1201. The center of the conveying roller 12 is fixedly connected to a rotating handle 6. The rotating handle 6 is rotatably connected to the side wall of the outer shell 5. The discharge port at the bottom of the outer shell 5 is fixedly connected to a discharge pipe 7.

[0030] It is worth noting that the outer shell 5 is made of transparent material, which makes it easy to observe the specific location of the metering groove 1201 on the surface of the conveying roller 12.

[0031] It should be noted that: by rotating the handle 6, the conveying roller 12 is driven to rotate. When the metering groove 1201 on the surface of the conveying roller 12 rotates to the opening at the bottom of the unpacking box 1, the silica inside the unpacking box 1 will automatically enter the metering groove 1201, so that the metering groove 1201 is filled, realizing the automatic metering function of silica, which makes it easy to control the granulation quantity of silica in a single batch.

[0032] The advantage of taking the above operation is that the outer shell 5 can ensure that the silica is in a closed environment during the pouring process, thus preventing the silica from leaking into the external environment and causing dust pollution.

[0033] Furthermore, a powder pump 10 is installed on the side wall of the bag removal box 1. One end of the powder pump 10 is connected to the bag removal box 1 through an air extraction pipe. Furthermore, an exhaust pipe is fixedly connected to the other end of the powder pump 10. A one-way valve 11 is installed on the exhaust pipe. A filter bag 9 is threadedly connected to one end of the exhaust pipe through a threaded joint 16.

[0034] It should be noted that after all the silica inside the bag opening box 1 has been emptied, the powder pump 10 is turned on (the powder pump 10 is existing technology, and its specific working principle will not be described here). The powder pump 10 draws the silica dispersed inside the bag opening box 1 into the inside of the filter bag 9, so as to prevent the silica dispersed inside the bag opening box 1 from being dispersed into the air when the bag opening box 1 is opened.

[0035] It is worth noting that by rotating the threaded joint 16, the threaded joint 16 (which is similar to an internally threaded pipe structure) can be separated from the exhaust pipe at one end of the powder pump 10, thereby enabling the removal of the filter bag 9 and facilitating the emptying and recycling of the white carbon black that has settled inside the filter bag 9.

[0036] Furthermore, a clamping screw 8 is rotatably provided on one side wall of the bag-removing box 1 opposite to the cutting component, and a push plate is rotatably connected to one end of the clamping screw 8.

[0037] It should be noted that before placing the white carbon black packaging bag inside the unpacking box 1, one end of the packaging bag should be held and shaken to allow the white carbon black inside the packaging bag to gather at the other end, creating a blank area at one end of the packaging bag. Then, the packaging bag is placed inside the unpacking box 1, ensuring that the end of the packaging bag with the gathered white carbon black contacts the bottom of the inner side of the unpacking box 1. By rotating the clamping screw 8, the push plate moves, working in conjunction with the inner wall of the unpacking box 1 to clamp and fix the other end of the packaging bag (the end with the blank area, where there is no white carbon black, and the push plate can clamp and fix the packaging bag), thus achieving the function of fixing the packaging bag inside the unpacking box 1.

[0038] When using this utility model, the feeding pipe 7 is attached to the feed inlet at the top of the granulator, and the blade 14 is moved to one end. Then, the packaging bag containing white carbon black is placed inside the unpacking box 1. Before this, one end of the packaging bag needs to be held and shaken so that the white carbon black inside the packaging bag gathers at the other end of the packaging bag, leaving a blank area at one end of the packaging bag. After the packaging bag is placed inside the unpacking box 1, the clamping screw 8 is rotated to move the pressure plate and cooperate with the inner wall of the unpacking box 1 to clamp and fix the packaging bag in the blank area, thereby fixing the packaging bag inside the unpacking box 1.

[0039] Then, the drive screw 3 is rotated, causing the nut block 4 on the surface of the drive screw 3 to move along the drive screw 3, which in turn drives the outer magnetic block 15 connected to the nut block 4 to move. The outer magnet drives the inner magnet to move through magnetic attraction, and the inner magnet drives the blade 14 to move, which can cut open the packaging bag containing white carbon black, so that the white carbon black inside the packaging bag is automatically poured into the bag opening box 1, ensuring that the white carbon black bag opening process is in a closed environment, and preventing the white carbon black dispersed during the bag opening process from leaking into the external environment and causing dust pollution.

[0040] By rotating the handle 6, the conveying roller 12 is driven to rotate. When the metering groove 1201 on the surface of the conveying roller 12 rotates to the opening at the bottom of the bag-removing box 1, the white carbon black inside the bag-removing box 1 will automatically enter the metering groove 1201, making the metering groove 1201 full. When the metering groove 1201 rotates to the feed inlet at the top of the granulator, the white carbon black inside the metering groove 1201 will automatically enter the feed inlet, automatically realizing the automatic metering function of white carbon black, which makes it easy to control the granulation quantity of white carbon black in a single batch. At the same time, the white carbon black is completely in a closed environment during the process of entering the feed inlet, avoiding the leakage of dispersed white carbon black into the external environment during the pouring process, which would cause dust pollution.

[0041] After the silica inside the bag opening box 1 is poured out, the powder pump 10 is turned on. The powder pump 10 draws the silica dispersed inside the bag opening box 1 into the inside of the filter bag 9, so as to prevent the silica dispersed inside the bag opening box 1 from being dispersed into the air when the bag opening box 1 is opened.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
