Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and more specifically to a hot air drying device for precipitated silica. Background Technology

[0002] Silica is a white powder. - The term "radiation-induced amorphous silica and silicate products" mainly refers to precipitated silica, fumed silica, and ultrafine silica gel, as well as powdered synthetic aluminum silicate and calcium silicate. Silica, as an environmentally friendly and high-performance additive, is hygroscopic and therefore requires drying before packaging.

[0003] A search revealed an existing patent (publication number: CN221944713U) that discloses a drying device for silica production. In its operation, silica raw material is added to the filter cylinder through a feed pipe. A hot air blower is activated to discharge hot air for drying the raw material. Then, a forward-starting motor drives a screw to rotate, causing a vertical block to move backward. The vertical block, through a rack, drives a semi-circular gear ring to rotate in the opposite direction. The semi-circular gear ring then drives the filter cylinder to rotate in the opposite direction. The continuous forward and reverse operation of the motor drives the filter cylinder to rotate in both directions, causing the raw material to tumble. The hot air ensures uniform drying of the raw material. The raw material slides into a guide hood and is discharged through a discharge pipe. This design gives the silica drying device a material-tumbling function, enabling uniform drying and improving drying efficiency. However, in the process of realizing this utility model, the inventors discovered the following problems with the prior art: When drying silica, the above-mentioned drying device simply puts the silica raw material into the filter cylinder and drives the filter cylinder to rotate to perform the material turning action. However, silica powder tends to harden after being exposed to moisture. When drying the agglomerated silica powder, it is difficult to crush the agglomerated silica, making it difficult to dry the inside.

[0004] In view of this, the present invention proposes a hot air drying device for precipitated silica to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a hot air drying device for precipitated silica to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a hot air drying device for precipitated silica, including a base frame, an mounting frame provided on the inner surface of the base frame, a drying cylinder rotatably connected to the inner wall of the mounting frame, drying holes evenly opened on the outer wall of the drying cylinder, a material port reserved at the end of the drying cylinder, a drive motor fixedly mounted on the surface of the mounting frame, a drive gear fixedly mounted on the output shaft surface of the drive motor, a driven gear ring fixedly mounted on the surface of the drying cylinder, the drive gear meshing with the driven gear ring, a hot air blower fixedly mounted at the bottom end of the mounting frame, an air supply pipe fixedly mounted at the air outlet end of the hot air blower, the air supply pipe extending into the interior of the drying cylinder and evenly opened with several air outlet holes, and an extrusion assembly provided on the surface of the air supply pipe;

[0007] The extrusion assembly includes two mounting plates fixedly installed on the surface of the air supply pipe. Each of the two mounting plates has a telescopic groove at the end away from the air supply pipe. Telescopic plates are slidably connected inside the two telescopic grooves. An extrusion roller is rotatably connected between the two telescopic plates. The extrusion roller is in contact with the inner wall of the drying cylinder.

[0008] Furthermore, a control panel is fixedly mounted on the surface of the base frame, and the control panel is electrically connected to an external power source via wires.

[0009] Furthermore, the base frame has four mounting holes on its surface, which are arranged in a rectangular array at the four corners of the base frame.

[0010] As a further description of the above technical solution: by setting mounting holes and inserting external screws into the mounting holes, the purpose of installing the base frame and the external structure can be achieved.

[0011] Furthermore, the air inlet of the hot air blower is equipped with a dust filter.

[0012] As a further description of the above technical solution: by setting up a dust filter, the air entering the hot air blower can be filtered to prevent dust in the air from mixing with the raw materials and causing pollution.

[0013] Furthermore, an ejector spring is fixedly installed on the inner wall of the telescopic groove, and the other end of the ejector spring is fixed to the end of the telescopic plate.

[0014] As a further description of the above technical solution: by setting an ejector spring, the telescopic plate can be driven to move outside the telescopic groove of the mounting plate, ensuring the pressing effect between the extrusion roller and the raw material. When the raw material is too hard, the ejector spring can retract, allowing the extrusion roller to avoid the raw material and prevent damage to the extrusion roller.

[0015] Furthermore, two shafts are symmetrically fixedly mounted on the surface of the mounting frame. The two shafts are rotatably connected to the base frame, and a deflection discharge assembly is provided between the base frame and the shafts. The deflection discharge assembly includes a drive box fixedly mounted on the surface of the base frame. The shafts are rotatably connected to the drive box. The shafts extend into the interior of the drive box and are fixedly mounted with a gear plate. A hydraulic rod is embedded in the surface of the drive box. The telescopic end of the hydraulic rod extends into the interior of the drive box and is fixedly mounted with a rack. The rack meshes with the gear plate.

[0016] As a further description of the above technical solution: by setting up a deflection discharge component, after drying, the rack can be driven to move by controlling the extension and retraction of the hydraulic rod. Based on the meshing of the rack and the toothed disc, the shaft and the mounting bracket can be driven to deflect, so that the material outlet faces downward to achieve the purpose of rapid material discharge.

[0017] Furthermore, a driven rod is rotatably connected to the surface of the mounting bracket, and a transmission gear is fixedly installed at the end of the driven rod. The transmission gear meshes with the driven gear ring. A tension spring is fixedly installed on the surface of the driven rod, and a striking ball is fixedly installed at the other end of the tension spring. When the driven rod rotates, the striking ball strikes and vibrates the surface of the drying cylinder.

[0018] As a further description of the above technical solution: During the drying process of the raw material, the drying cylinder rotates continuously. By using the meshing of the transmission gear and the driven gear ring, the driven rod can be driven to rotate, so that the tension spring drives the striking ball to strike and vibrate the surface of the drying cylinder, so that the raw material can be released from the surface of the drying hole, avoiding the situation where the raw material gets stuck inside the drying hole and causes blockage. It also ensures that when the raw material is discharged later, the raw material can be completely released from the inside of the drying cylinder, avoiding the situation where the raw material gets stuck inside the drying hole and causes raw material residue.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] 1. Compared with the prior art, this hot air drying device for silica feeds silica raw materials into the drying cylinder through the feed inlet. Hot air is blown into the drying cylinder through the air supply pipe and air outlet by a hot air blower. Subsequently, the moisture is discharged to the outside through the drying hole, which can dry the raw materials. During the process, the drying cylinder is rotated by a drive motor, which can turn the raw materials. In addition, by setting up an extrusion component, the extrusion rollers are used to crush the agglomerated raw materials during the rotation of the drying cylinder, thereby ensuring the degree of drying of the raw materials and avoiding the situation where the raw materials are difficult to dry due to agglomeration.

[0021] 2. Compared with the prior art, this hot air drying device for silica can achieve the purpose of installing the base frame and external structure by setting mounting holes and inserting external screws inside the mounting holes; by setting dust filter screen, the air entering the hot air blower can be filtered to avoid dust in the air mixing with the raw materials and causing pollution; by setting ejection spring, the telescopic plate can be driven to move out of the telescopic groove of the mounting plate to ensure the pressing effect between the extrusion roller and the raw material, and when the raw material is too hard, the ejection spring can retract, so that the extrusion roller avoids the raw material and prevents damage to the extrusion roller.

[0022] 3. Compared with the existing technology, this hot air drying device for precipitated silica, by setting up a deflection discharge component, can drive the rack to move by controlling the extension and retraction of the hydraulic rod after drying. Based on the meshing of the rack and the toothed disc, it can drive the shaft and the mounting frame to deflect, so that the material outlet faces downward to achieve the purpose of rapid material discharge.

[0023] 4. Compared with the prior art, in the process of drying raw materials, the drying cylinder of this hot air drying device rotates continuously. The meshing of the transmission gear and the driven gear ring drives the driven rod to rotate, which causes the tension spring to drive the striking ball to strike and vibrate the surface of the drying cylinder. This allows the raw material to be released from the surface of the drying hole, avoiding the situation where the raw material gets stuck inside the drying hole and causes blockage. It also ensures that the raw material can be completely released from the inside of the drying cylinder when discharging the raw material, avoiding the situation where the raw material gets stuck inside the drying hole and causes raw material residue.

[0031] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The hot air drying device for precipitated silica involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Reference Figures 1 to 6 This utility model provides a hot air drying device for precipitated silica, including a base frame 1, a control panel 14 fixedly mounted on the surface of the base frame 1, and the control panel 14 electrically connected to an external power source through wires.

[0033] The base frame 1 has four mounting holes 15 on its surface, which are arranged in a rectangular array at the four corners of the base frame 1.

[0034] By setting mounting holes 15 and inserting external screws into the mounting holes 15, the purpose of installing the base frame 1 with the external structure can be achieved.

[0035] A mounting bracket 2 is provided on the inner surface of the base frame 1. A drying cylinder 3 is rotatably connected to the inner wall of the mounting bracket 2. Drying holes 9 are evenly opened on the outer wall of the drying cylinder 3. A material port is reserved at the end of the drying cylinder 3. A drive motor 4 is fixedly installed on the surface of the mounting bracket 2. A drive gear 5 is fixedly installed on the output shaft surface of the drive motor 4. A driven gear ring 6 is fixedly installed on the surface of the drying cylinder 3. The drive gear 5 and the driven gear ring 6 mesh. A hot air blower 7 is fixedly installed at the bottom end of the mounting bracket 2. An air supply pipe 8 is fixedly installed at the air outlet end of the hot air blower 7. The air supply pipe 8 extends into the interior of the drying cylinder 3 and is evenly opened with several air outlet holes 10.

[0036] It is worth noting that in this hot air drying device for silica, silica raw materials are fed into the drying cylinder 3 through the feed inlet. Hot air is driven by the hot air blower 7 and blown into the drying cylinder 3 through the air supply pipe 8 and the air outlet 10. Then, the moisture is discharged to the outside through the drying hole 9, which can dry the raw materials. In addition, during the process, the drying cylinder 3 is driven to rotate by the drive motor 4, which can turn the raw materials to ensure the drying effect of the raw materials.

[0037] The air inlet of the hot air blower 7 is equipped with a dust filter 16.

[0038] By setting up the dust filter 16, the air entering the hot air blower 7 can be filtered to prevent dust in the air from mixing with the raw materials and causing pollution.

[0039] The surface of the air supply duct 8 is provided with an extrusion component.

[0040] The extrusion assembly includes two mounting plates 11 fixedly installed on the surface of the air supply pipe 8. Each of the two mounting plates 11 has a telescopic groove at the end away from the air supply pipe 8. A telescopic plate 12 is slidably connected inside the two telescopic grooves. An extrusion roller 13 is rotatably connected between the two telescopic plates 12. The extrusion roller 13 is in contact with the inner wall of the drying cylinder 3.

[0041] An ejector spring 17 is fixedly installed on the inner wall of the telescopic groove, and the other end of the ejector spring 17 is fixed to the end of the telescopic plate 12.

[0042] It is worth noting that by setting up the extrusion assembly, during the rotation of the drying cylinder 3, the extension spring 17 supports the telescopic plate 12, which can drive the telescopic plate 12 to move outside the telescopic groove of the mounting plate 11, ensuring the pressing effect between the extrusion roller 13 and the raw material. The extrusion roller 13 is used to extrude and crush the agglomerated raw material, thereby ensuring the degree of drying of the raw material and avoiding the situation where the raw material agglomerates and is difficult to dry.

[0043] Furthermore, when the raw material is too hard, the ejector spring 17 can retract, allowing the extrusion roller 13 to avoid the raw material and prevent damage to the extrusion roller 13.

[0044] Two shafts 18 are symmetrically fixedly mounted on the surface of the mounting frame 2. The two shafts 18 are rotatably connected to the base frame 1, and a deflection discharge assembly is provided between the base frame 1 and the shafts 18.

[0045] The deflection discharge assembly includes a drive box 19 fixedly mounted on the surface of the base frame 1, a shaft 18 rotatably connected to the drive box 19, the shaft 18 extending into the interior of the drive box 19 and a gear plate 20 fixedly mounted thereon, a hydraulic rod 21 embedded in the surface of the drive box 19, the telescopic end of the hydraulic rod 21 extending into the interior of the drive box 19 and a rack 22 fixedly mounted thereon, the rack 22 meshing with the gear plate 20.

[0046] It is worth noting that by setting up a deflection discharge component, after drying, the hydraulic rod 21 can be extended and retracted to drive the rack 22 to move. Based on the meshing of the rack 22 with the gear plate 20, the shaft 18 and the mounting bracket 2 can be deflected, so that the material outlet of the drying cylinder 3 faces downward to achieve the purpose of rapid material discharge.

[0047] A driven rod 23 is rotatably connected to the surface of the mounting bracket 2. A transmission gear 24 is fixedly installed at the end of the driven rod 23. The transmission gear 24 meshes with the driven gear ring 6. A tension spring 25 is fixedly installed on the surface of the driven rod 23. A striking ball 26 is fixedly installed at the other end of the tension spring 25. When the driven rod 23 rotates, the striking ball 26 strikes and vibrates the surface of the drying cylinder 3.

[0048] It is worth noting that in the process of drying raw materials, the drying cylinder 3 of this hot air drying device continuously rotates. The transmission gear 24 and the driven gear ring 6 mesh to drive the driven rod 23 to rotate, which causes the tension spring 25 to drive the striking ball 26 to strike and vibrate the surface of the drying cylinder 3. This allows the raw material to fall back into the drying cylinder 3 from the drying hole 9 at the top, avoiding the situation where the raw material gets stuck in the drying hole 9 and causes blockage of the exhaust channel. Furthermore, when the raw material is discharged, since the raw material can be completely removed from the inside of the drying cylinder 3, it can avoid the situation where the raw material gets stuck in the drying hole 9 and causes raw material residue.

[0049] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
