Abstract

This utility model belongs to the field of sulfur raw material technology, specifically disclosing a sulfur raw material feeding device to prevent blockage. It includes a conveying shell, with a vibration assembly installed at the top of the conveying shell to break up sulfur bridging. The vibration assembly includes a vibration motor fixedly connected inside a support column; a cam is fixedly connected to the output end of the vibration motor; a rotating shaft is movably mounted on the surface of the support column; a transmission plate is fixedly connected to the outer side of the rotating shaft, located on the side of the cam; and a striking column is fixedly connected to the side of the transmission plate. This utility model uses the vibration motor to drive the cam to rotate, causing the transmission plate to move back and forth around the rotating shaft, thereby driving the striking column to strike the surface of the raw material hopper.

The fluidization component further facilitates smoother material flow and reduces blockage.

Description

Technical Field

[0001] This utility model belongs to the field of sulfur raw material technology, specifically a sulfur raw material feeding device that prevents clogging. Background Technology

[0002] Sulfur, especially in powder or small lump form, is prone to problems such as arching, bridging, sticking to walls, and clogging during storage and transportation due to its physical properties (hygroscopicity, static electricity generation, and poor flowability). This can lead to uneven feeding or even interruption of production, severely impacting subsequent processes (such as sulfuric acid production and rubber vulcanization). Therefore, a dedicated anti-clogging feeding device is crucial.

[0003] A search revealed a screw feeder with anti-clogging and anti-bridging publication number CN205034671U, comprising a hopper, a feeding housing, a feeding screw, a pusher motor, a transmission sprocket and chain, a splined shaft, a trapezoidal screw, and a crank handle. The pusher motor, connected to the splined shaft via the transmission sprocket and chain, drives the feeding screw to rotate and feed material through the feeding housing. The feeding screw is fixed to the splined shaft, which has a screw fixing joint inside. One end of the trapezoidal screw is mounted on the screw fixing joint, and the other end is connected to the crank handle. The rotation of the trapezoidal screw pushes the splined shaft to move horizontally along the axial direction, thereby causing the feeding screw to move horizontally along the discharge direction. This device eliminates the need to disassemble equipment parts, can clear blockages online, reduces labor intensity, and increases efficiency. Overall, it lowers production costs and brings significant economic value.

[0004] While the aforementioned technical solutions can clear blockages online with low labor intensity and high efficiency, they are not perfect in terms of sulfur storage and transportation. Especially during transverse stirring within the hopper, sulfur raw materials can adhere to the inner wall, making it difficult for the material to flow out and requiring manual cleaning when blockages occur. Therefore, a device is needed to automatically clean the adhering substances from the inner wall, facilitating the smooth flow of raw materials from the hopper. Utility Model Content

[0005] To address the above technical problems, this utility model provides a device that can automatically clean the adhering substances on the inner wall, thereby facilitating the smooth flow of raw materials in the hopper. This solves the problems of existing feeding devices having poor material flow, easily adhering to the inner wall of the hopper, and being prone to clogging.

[0006] To solve the above technical problems, the technical solution of this utility model is as follows: a sulfur raw material feeding device for preventing blockage, comprising a conveying shell, a support column and a raw material bin fixedly connected to the top of the conveying shell, the support column being located on one side of the raw material bin, a vibration assembly fixedly connected to the support column, the vibration assembly including a servo motor fixedly connected to the support column, a cam fixedly connected to the output end of the servo motor, a rotating shaft fixedly connected to the side wall of the support column, a transmission plate rotatably connected to the rotating shaft, a striking column fixedly connected to the lower side of one side of the transmission plate, and the upper part of the other side contacting the cam, a fluidizing assembly fixedly connected to the outer side and the inner side of the raw material bin, a stirring motor fixedly connected to the top of the raw material bin, a stirring shaft rotatably connected inside, the output end of the stirring motor fixedly connected to the upper end of the stirring shaft, a conveying motor fixedly connected to the side wall of the conveying shell, a discharge port opened on the other side, and an auger conveyor rotatably connected inside, one end of the auger conveyor fixedly connected to the output end of the conveying motor.

[0007] Furthermore, the fluidization assembly includes a porous fluidizing plate fixedly connected to the inner wall of the raw material silo and an air conveying plate fixedly connected to the bottom of the outer side of the raw material silo. The porous fluidizing plate is fixedly connected to an air conveying pipe, and the other end of the air conveying pipe is connected to the air conveying plate. An air inlet is fixedly connected to the air conveying plate.

[0008] Furthermore, a door opening and closing assembly is installed between the raw material silo and the conveying shell. The door opening and closing assembly includes a movable groove, which is formed on the top wall of the conveying shell. A movable plate is slidably connected inside the movable groove.

[0009] Furthermore, a movable plate is fixedly connected to the top of the movable plate, and an electric push rod is fixedly connected to the upper surface of the conveying shell. The output end of the electric push rod is fixedly connected to one side of the movable plate.

[0010] Furthermore, a feed inlet is fixedly connected to the top of the raw material silo, and the feed inlet is located on one side of the stirring motor.

[0011] Furthermore, a stirring arm is fixedly connected to the upper part of the stirring shaft.

[0012] This utility model has the following advantages compared with the prior art:

[0013] 1. This utility model uses a servo motor to drive a cam to rotate, which causes the transmission plate to move back and forth around the rotating shaft. This causes the striking column to strike the surface of the raw material bin, generating high-frequency, low-amplitude vibrations that break up the newly formed arch bridge. The stirring motor drives the stirring shaft and stirring arm to crush the hardened raw material inside the bin, thus preventing blockage and ensuring normal supply. Dry, stable, low-pressure air is injected into the air pipe on the support plate, allowing the air to enter the interior of the raw material bin through the porous fluidizing plate. This creates an air film between the sulfur particles, giving it excellent fluidity and preventing blockage.

[0014] 2. This utility model uses an electric push rod to move a movable plate, which in turn moves a movable plate back and forth inside the movable trough, thereby closing and opening the raw material silo to ensure the dryness and stability of the raw material silo. The conveyor motor drives the auger conveyor to rotate, thereby discharging the falling raw materials from the discharge port, thus supplying the raw materials. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figures 1 to 5The illustrated anti-clogging sulfur feeder includes a conveying shell 1. A support column 4 and a raw material hopper 2 are fixedly connected to the top of the conveying shell 1. The bottom of the raw material hopper 2 is connected to the top of the conveying shell and is connected to the movable groove 51 through the cooperation of a movable plate 52. The support column 4 is located on one side of the raw material hopper 2. A vibration assembly is fixedly connected to the support column 4. The vibration assembly includes a servo motor 41 fixedly connected to the support column 4. A cam 42 is fixedly connected to the output end of the servo motor 41. A rotating shaft 44 is fixedly connected to the side wall of the support column 4. A transmission plate 45 is rotatably connected to the rotating shaft 44. A striking column 43 is fixedly connected to the lower side of one side of the transmission plate 45, and the upper part of the other side contacts the cam 42. The other side of the striking column 43 contacts the side wall of the raw material hopper 2. The rotation of the servo motor 41 drives the cam 42 to rotate. During rotation, the cam contacts the upper end of the transmission plate 45, causing the transmission plate 45 to swing around the rotating shaft 44. Under the action of the weight of the striking column 43, it strikes the side wall of the raw material bin 2, breaking up the arch bridge formed by the raw material inside. The outside and inside of the raw material bin 2 are fixedly connected to a fluidizing component 7. The fluidizing component 7 can make the raw material inside fall more easily, which facilitates discharge and prevents blockage. The top of the raw material bin 2 is fixedly connected to a stirring motor 21, and the inside is rotatably connected to a stirring shaft 22. The output end of the stirring motor 21 is fixedly connected to the upper end of the stirring shaft 22. The side wall of the conveying shell 1 is fixedly connected to a conveying motor 6, and the other side is provided with a discharge port 8. The inside is rotatably connected to an auger conveyor 9. One end of the auger conveyor 9 is fixedly connected to the output end of the conveying motor 6. The output end of the auger conveyor 9 coincides with the discharge port 8, which facilitates better discharge.

[0023] It should be noted that in this embodiment, the servo motor 41, stirring motor 21, conveying motor 6, and electric push rod 54 are all electrically connected to an external power source to provide sufficient power to the device.

[0024] In order to fill the raw material silo 2 with gas, an air film is added between the raw materials to prevent blockage and make the raw materials flow more smoothly. The fluidization component 7 includes a porous fluidizing plate 73 fixedly connected to the inner wall of the raw material silo 2 and an air conveying plate 71 fixedly connected to the bottom of the outer side of the raw material silo 2. The porous fluidizing plate 73 is connected to the inner wall of the bottom of the raw material silo 2. An air conveying pipe 72 is fixedly connected to the porous fluidizing plate 73. The other end of the air conveying pipe 72 is connected to the air conveying plate 71. An air inlet 74 is fixedly connected to the air conveying plate 71. The air conveying pipe 72 first sends the gas into the inner wall space of the raw material silo 2, and then sends it into the interior of the raw material silo 2 through the porous fluidizing plate 73. The air inlet 74 is connected to an external air pump, which can fill the interior with dry low-pressure air.

[0025] In order to facilitate the control of the feeding time of raw materials in the raw material silo 2, and to facilitate the temporary storage of raw materials in the raw material silo 2 for stirring and crushing, a door opening and closing assembly 5 is installed between the raw material silo 2 and the conveying shell 1. The door opening and closing assembly 5 includes a movable groove 51, which is opened on the top wall of the conveying shell 1. A movable plate 52 is slidably connected inside the movable groove 51.

[0026] In order to control the door opening and closing assembly 5, a movable plate 53 is fixedly connected to the top of the movable plate 52, and an electric push rod 54 is fixedly connected to the upper surface of the conveying shell 1. The output end of the electric push rod 54 is fixedly connected to one side of the movable plate 53.

[0027] In order to facilitate the addition of raw materials into the raw material silo 2, a feed inlet 3 is fixedly connected to the top of the raw material silo 2, and the feed inlet 3 is located on one side of the stirring motor 21.

[0028] In order to improve the mixing efficiency, a mixing arm 23 is fixedly connected to the mixing shaft 22. The mixing arm 23 is cylindrical and is set on the entire mixing shaft 22.

[0029] The specific working process of this utility model is as follows:

[0030] In use, raw materials are added to the inside of the raw material bin 2 through the feed inlet 3. The stirring motor 21 is then started, which drives the stirring shaft 22 and the stirring arm 23 to rotate, thereby mechanically breaking up arches and clumps. The raw material bin 2 adopts a conical bucket design: it uses a large cone angle (usually greater than 70°) or a parabolic / hyperbolic bucket shape. This shape can reduce the squeezing and shearing forces between materials, making it easier for the materials to slide down naturally under gravity. The inner wall of the raw material bin 2 is polished to achieve a mirror finish, which greatly reduces the coefficient of friction and prevents sulfur from adhering. Dry, stable, low-pressure air is injected into the air supply pipe 72 on the air supply plate 71, allowing the air to enter the interior of the raw material bin 2 through the porous fluidizing plate 73. This creates an air film between the sulfur particles, giving it excellent fluidity. The servo motor 41 on the support column 4 is activated, driving the cam 42 to rotate. This causes the transmission plate 45 to move back and forth around the rotating shaft 44, which in turn drives the striking column 43 to strike the surface of the raw material bin 2. This generates high-frequency, low-amplitude vibrations, breaking up the newly formed arch bridge and preventing the raw material from clogging. When the mixing is finished and the raw material needs to be transported out, the electric push rod 54 is activated. The electric push rod 54 drives the moving plate 53 to move, which in turn drives the movable plate 52 to move back and forth inside the movable trough 51, thereby closing and opening the raw material bin 2. After opening, the raw material inside the raw material bin 2 can fall into the interior of the conveying shell 1. The conveying motor 6 is activated, driving the auger conveyor 9 to rotate, thereby discharging the falling raw material from the discharge port 64.
