Description

Technical Field

[0001] This utility model relates to a discharge device for viscous materials (such as non-magnetic materials in a slurry pretreatment magnetic separator), and belongs to the field of conveying equipment technology. Background Technology

[0002] In industrial production processes, pipelines are frequently used to discharge or transport materials with a certain degree of viscosity. For example, in the operation of a magnetic separator (a device that separates materials based on the principle that magnetic and non-magnetic materials experience different forces in a magnetic field), after the slurry flows into the tank through the feed box, the mineral particles enter the feed area of ​​the tank in a loose state under the action of water flow from the feed spray pipe. Under the influence of the magnetic field, the magnetic particles magnetically aggregate to form "magnetic clusters" or "magnetic chains." These "magnetic clusters" or "magnetic chains" are attracted to the magnetic poles by the magnetic force in the slurry and are adsorbed onto the cylinder. Then, as the cylinder rotates, the magnetic and non-magnetic materials are separated, with the magnetic materials being discharged and the non-magnetic materials being discharged through the discharge pipe under the action of water flow. Because some non-magnetic materials become sticky when wet, they easily adhere to the inner wall of the discharge pipe during discharge, causing blockage and reducing discharge efficiency. Therefore, how to smoothly discharge or transport sticky materials has always been a difficult problem for relevant technicians. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a discharge device for viscous materials, thereby preventing viscous materials from clogging the discharge pipe and ensuring the normal operation of the equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A discharge device for viscous materials includes a vibrating base, a discharge pipe assembly, and a pneumatic unblocking device. The discharge pipe assembly includes a discharge pipe mounted on the vibrating base. Both the inlet and outlet ends of the discharge pipe are provided with flexible connecting mechanisms. The pneumatic unblocking device includes an air pump and an air outlet pipe. One end of the air outlet pipe is connected to the airflow output end of the air pump, and the other end communicates with the inner cavity of the discharge pipe through an air inlet on the side wall of the discharge pipe.

[0005] The above-mentioned discharge device for viscous materials includes a flexible connection mechanism comprising a corrugated pipe and a flange, wherein one end of the corrugated pipe is connected to the end of the discharge pipe and the other end is connected to the flange.

[0006] The discharge device for the above-mentioned viscous material includes two symmetrical semi-circular tubular clamping shells, which are spliced ​​together to form a circular tube and fixedly fitted onto the outside of the discharge pipe. The vibration base is connected to the discharge pipe through the lower clamping shell, and a protective shell is fixedly connected to the top of the upper clamping shell. The top of the protective shell has multiple ventilation holes, and the air pump is installed inside the protective shell.

[0007] The above-mentioned discharge device for viscous materials includes two air pumps, which are symmetrically installed on both sides of the inner side of the protective shell. The air outlet pipes of the two air pumps are connected to different parts of the inner cavity of the discharge pipe.

[0008] The aforementioned discharge device for viscous materials has a hollowed-out clamping shell, and the two clamping shells are fixedly connected by bolts.

[0009] The aforementioned discharge device for viscous materials includes a vibrating base comprising a main shell. A U-shaped connecting frame is fixed to the upper part of the bottom plate of the main shell. Two pairs of symmetrical transverse sliding rods are provided on the two vertical arms of the U-shaped connecting frame. Each pair of transverse sliding rods is arranged vertically and parallel to the bottom crossbeam of the U-shaped connecting frame. Each transverse sliding rod slides through a horizontal guide hole on the vertical arm of the U-shaped connecting frame. A swaying bracket is fixedly connected between the two pairs of transverse sliding rods. A transverse buffer spring is sleeved on each transverse sliding rod. The two ends of the transverse buffer spring respectively abut against the swaying bracket and the U-shaped connecting frame. On the shaped connecting frame; two vertical sliding rods are symmetrically fixed on both sides inside the swing bracket. Vertical buffer springs are slidably fitted on the outside of each of the two vertical sliding rods. Each of the two vertical buffer springs has a sliding block in the middle that is slidably connected to the vertical sliding rod. A drive housing is fixed between the two sliding blocks. A dual-axis motor is fixedly connected inside the drive housing. Multiple eccentric blocks are fixedly connected to a pair of output ends of the dual-axis motor. A support rod is fixedly connected to the upper end of the drive housing. The upper end of the support rod passes through a rectangular hole at the top of the main housing and is connected to the clamping housing.

[0010] This invention utilizes a vibrating base to drive the discharge pipe to vibrate, causing the sticky material on the inner wall of the discharge pipe to fall off.

[0014] In order to overcome the shortcomings of the prior art, this utility model provides a discharge device for viscous materials, which effectively solves the problem of easy blockage in the discharge pipe in the prior art.

[0015] See Figures 1-5 This utility model mainly includes a discharge pipe assembly 4, a vibrating base 2, and a pneumatic unblocking device 3.

[0016] The vibration base 2 includes a main shell 201. A U-shaped connecting frame 202 is fixedly connected to the upper part of the base plate of the main shell 201. Two pairs of symmetrical transverse sliding rods 203 are slidably connected to the two vertical arms of the U-shaped connecting frame 202. Each pair of transverse sliding rods 203 is arranged vertically and parallel to the bottom crossbeam of the U-shaped connecting frame 202. Each transverse sliding rod 203 slides through a horizontal guide hole on the vertical arm of the U-shaped connecting frame 202. A swaying bracket 205 is fixedly connected between the two pairs of transverse sliding rods 203, that is, the swaying bracket 205 is fixedly connected to the opposite ends of the two pairs of transverse sliding rods 203. A transverse buffer spring 204 is sleeved in the middle of each transverse sliding rod 203. The two ends of the transverse buffer spring 204 rest on the swaying bracket 205 and the U-shaped connecting frame 202, respectively.

[0017] The main housing 201 provides mounting support for the internal components. The U-shaped connecting bracket 202 limits the sliding trajectory of the transverse sliding rod 203, allowing the swaying bracket 205 to vibrate laterally together with the transverse sliding rod 203. The transverse buffer spring 204 is used to absorb the impact force of transverse vibration, playing a transverse buffering role and preventing the equipment from shifting or being damaged due to transverse vibration.

[0018] like Figures 1 to 3As shown, two vertical sliding rods 206 are symmetrically fixedly connected to the two sides inside the rocking bracket 205. Vertical buffer springs 207 are slidably fitted on the outside of the two vertical sliding rods 206. The two ends of the two vertical buffer springs 207 are connected to the rocking bracket 205. A sliding block 208 is provided in the middle of the two vertical buffer springs 207. The sliding block 208 is slidably connected to the vertical sliding rod 206.

[0019] The swaying bracket 205 provides a fixed base for the vertical sliding rod 206. The vertical sliding rod 206 guides the sliding block 208 to slide up and down. When the sliding block 208 slides up and down, the vertical buffer spring 207 is compressed or stretched, thereby absorbing the vertical vibration impact force and playing a vertical buffering role, ensuring the effective transmission of vibration while protecting the safety of the components.

[0020] like Figures 1 to 3 As shown, a drive housing 209 is fixedly connected between the two sliding blocks 208. A dual-axis motor 210 is fixedly connected inside the drive housing 209. Multiple eccentric blocks 211 are fixedly connected to a pair of output ends of the dual-axis motor 210. A support rod 212 is fixedly connected to the upper end of the drive housing 209. The upper end of the support rod 212 is connected to the discharge pipe assembly 4.

[0021] The drive housing 209 provides mounting support for the dual-axis motor 210. The dual-axis motor 210 drives the eccentric block 211 to rotate at high speed to generate centrifugal force, causing the drive housing 209 to vibrate. The support rod 212 transmits the vibration to the discharge pipe assembly 4, providing high-frequency micro-vibration to the discharge pipe 401 to shake off the sticky material.

[0022] like Figure 2 As shown, the discharge pipe assembly 4 includes a discharge pipe 401, both ends of which are fixedly connected to a corrugated pipe 402, and the far end of each corrugated pipe 402 is fixedly connected to a flange 403.

[0023] The discharge pipe 401 serves as a non-magnetic conveying channel, the flange 403 enables the discharge pipe 401 to connect with external equipment, and the corrugated pipe 402 is used to adapt to the vibration of the discharge pipe 401, ensuring the sealing of the slurry conveying and preventing the pipe from breaking due to vibration.

[0024] like Figure 5 As shown, the pneumatic unblocking device 3 includes two symmetrical semi-circular tubular clamping shells 301. The two clamping shells 301 are spliced ​​into a circular tube and fixedly fitted onto the outside of the discharge pipe 401. The lower end of the lower clamping shell 301 is fixedly connected to the upper end of the support rod 212. The top of the upper clamping shell 301 is fixedly connected to a protective shell 302. Two mutually symmetrical air pumps 303 are fixedly connected to the inside sides of the protective shell 302. The output ends of the two air pumps 303 are connected to an air outlet pipe 304. The end of the air outlet pipe 304 away from the air pump 303 is connected to the inner cavity of the discharge pipe 401.

[0025] The clamping housing 301 connects to the support rod 212 and fixes the discharge pipe 401. The protective housing 302 is used to protect the air pump 303. The air pump 303 is used to generate high-pressure airflow. The air outlet pipe 304 delivers the airflow into the discharge pipe 401. The disturbance of the airflow promotes the flow of materials and impacts the sticky materials.

[0026] like Figure 5 As shown, the two clamping shells 301 are fixedly connected by bolts. The upper and lower clamping shells 301 are fixed by bolts, which facilitates subsequent disassembly and maintenance.

[0027] like Figure 5 As shown, both clamping shells 301 are hollowed out. The hollowed-out structure can reduce the weight of the clamping shells 301 themselves, reduce the load on the vibration base 2, and at the same time enable air circulation in the clamping area, improve vibration transmission efficiency and avoid local overheating.

[0028] The top of the protective housing 302 has multiple ventilation holes, which provide an air supply channel for the air inlet of the air pump 303 inside the protective housing 302, and facilitate the heat dissipation of the air pump 303, preventing the air pump 303 from being damaged due to high temperature overload.

[0029] Two air outlet pipes 304 are connected to different parts of the inner cavity of the discharge pipe 401, so that the high-pressure airflow can disturb the material at different parts (both ends) of the discharge pipe 401, ensuring the airflow disturbance effect. Its working principle is as follows: When discharging material through the discharge pipe 401, only one air pump 303 needs to be turned on. After the material is discharged, both air pumps 303 are turned on at the same time, and two air outlet pipes 304 blow air to both ends of the discharge pipe 401. The two air outlet pipes 304 correspond to the two corrugated pipes 402, and high-pressure airflow is used to clean the two corrugated pipes 402 to further enhance the cleaning effect and prevent material from settling inside the corrugated pipes 402.

[0030] like Figures 1 to 4 As shown, the top of the main body shell 201 has a rectangular hole corresponding to the support rod 212. The rectangular hole provides room for the support rod 212 to move, so as to avoid the support rod 212 being blocked by the main body shell 201 when transmitting vibration, and to ensure that the vibration can be effectively transmitted to the discharge pipe 401.

[0031] Working principle and usage process of this utility model: First, complete the assembly and connection of this device. Through the flange 403 at the end of the corrugated pipe 402 in the discharge pipe assembly 4, connect one end of the discharge pipe 401 to the discharge port of the discharge equipment (taking the iron ore magnetic separator 1 as an example), and connect the other end to the external waste collection equipment. At the same time, ensure that the bottom of the main shell 201 in the vibration base 2 is placed stably. Enhance the adhesion to the ground through the anti-slip structure to avoid overall displacement during subsequent operation. After the iron ore magnetic separator 1 completes the magnetic separation operation, the non-magnetic materials enter the discharge pipe 401 with the slurry. At this time, the dual-shaft motor 210 inside the drive housing 209 in the vibrating base 2 is started. The pair of output ends of the dual-shaft motor 210 drive multiple eccentric blocks 211 to rotate at high speed. Because the center of mass of the eccentric block 211 deviates from the axis of rotation, a periodic centrifugal force is generated, causing the drive housing 209 to vibrate. The vibration of the drive housing 209 is transmitted to the sliding block 208 fixedly connected to it. The sliding block 208 slides up and down along the vertical sliding rod 206 inside the swaying bracket 205. During the process, a pair of vertical buffer springs 207 are compressed or stretched to absorb part of the vertical vibration impact force, which ensures effective transmission of vibration and avoids excessive vibration that could damage the components. At the same time, the swaying bracket 205 drives the horizontal sliding rods 203 on both sides to slide left and right with the vibration. The horizontal buffer springs 204 inside the U-shaped connecting frame 202 deform accordingly to absorb the horizontal vibration impact force and maintain the overall stability of the equipment. Vibration is transmitted through the support rod 212 at the top of the drive housing 209 to the clamping housing 301 of the pneumatic unblocking device 3, and then through the clamping housing 301 to the discharge pipe 401. The support rod 212 moves flexibly in the rectangular hole at the top of the main housing 201 to ensure that the vibration is transmitted to the clamping housing 301 below without obstruction, thereby causing the discharge pipe 401 between the clamping housings 301 to generate high-frequency micro-vibration, shaking off non-magnetic materials stuck to the inner wall of the discharge pipe 401 and preventing accumulation and blockage. Simultaneously, the air pump 303 inside the protective casing 302 is activated. The high-pressure airflow generated by the air pump 303 is delivered to the discharge pipe 401 through the outlet pipe 304 at the output end, and then flows along the discharge direction of the discharge pipe 401, forming airflow disturbance. On the one hand, this pushes non-magnetic materials to move quickly towards the discharge end, reducing their residence time on the pipe wall; on the other hand, it impacts materials that are about to stick, creating a synergistic anti-clogging effect with the vibration. The vent at the top of the protective casing 302 provides an air supply channel for the air inlet of the air pump 303, while also timely dissipating the heat generated by the air pump 303 during operation, preventing the air pump 303 from being damaged due to high temperature overload. Throughout the discharge process, the corrugated pipe 402, with its flexible characteristics, adapts to the vibration of the discharge pipe 401, preventing the rigid connection of the pipe from breaking, while ensuring the sealing of the slurry transport. If maintenance is required, the bolts connecting the clamping casing 301 can be unscrewed, the upper and lower clamping casings 301 can be disassembled, and maintenance can be performed on the discharge pipe 401 or the outlet pipe 304 without disassembling the entire equipment, making the operation convenient.After the material discharge operation is completed, first turn off the air pump 303. After the residual material in the discharge pipe 401 is emptied, turn off the dual-shaft motor 210 to complete one operation cycle. Subsequently, the speed of the dual-shaft motor 210 and the air pressure of the air pump 303 can be adjusted by the controller of the iron ore magnetic separator 1 according to the working conditions such as the viscosity of the slurry, to ensure efficient anti-clogging under different working conditions.

[0032] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model solves the problem of clogging by viscous materials from two dimensions: physical contact and fluid disturbance, through the synergistic design of "vibration and airflow". It effectively avoids the blockage of the discharge pipe caused by viscous materials, ensuring continuous and stable operation. The flexible characteristics of the corrugated pipe in the discharge pipe assembly can adapt to the vibration generated by the vibration base, preventing the pipe from breaking during vibration due to rigid connection. At the same time, the horizontal buffer spring and the vertical buffer spring can absorb the horizontal and vertical vibration impact forces respectively, reducing the wear of the overall structure of the equipment.

[0033] 2. The components of this utility model adopt a modular design. For example, the clamping shell can be detachably connected by bolts, and the discharge pipe and the corrugated pipe are independent components. The overall structure is compact. During installation, only the pipe connection needs to be completed through the flange. During maintenance, there is no need to disassemble the entire equipment. Only the corresponding components need to be disassembled, making maintenance and operation convenient.
