[0039] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0040] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0041] Example 1

[0042] Existing methods for preparing mud balls are still mainly manual or semi-mechanized, which suffer from problems such as low efficiency, unstable quality, and high labor intensity, making it difficult to meet the needs of large-scale and standardized production.

[0043] To address the aforementioned problems in the prior art, this embodiment provides a mud ball preparation system for preparing plugging mud balls used in industrial silicon smelting. This mud ball preparation system automates the entire production process from raw material preparation to finished mud balls, improving production efficiency and reducing labor intensity. Please refer to... Figures 1-4 The mud ball preparation system mainly includes: a first conveying unit 100, a mixing unit 200, an extrusion ball-making unit 300, a second conveying unit 400, and a control unit, etc.

[0044] The first conveying unit 100 is used to convey the raw materials used in preparing mud balls from the raw material storage area to the preparation system. For example... Figure 1 , Figure 2As shown in the figure, the raw materials used to prepare the mud balls in this embodiment mainly include graphite and yellow clay. The first conveying unit 100 needs to input the two raw materials from two raw material storage areas. Therefore, the first conveying unit 100 mainly includes a first conveying module for conveying graphite raw materials and a second conveying module for conveying yellow clay raw materials. Among them, the first conveying module mainly consists of a single beam crane 110, a first bucket elevator 120, a first hopper 130, and a first screw conveyor 140. A single-girder overhead crane 110 is positioned between the graphite raw material storage area and the first bucket elevator 120. It transports the graphite raw material to the bottom of the first bucket elevator 120. After receiving the graphite raw material, the first bucket elevator 120 lifts it to the top. The upper part of the first bucket elevator 120 connects to the inlet of the first hopper 130, allowing the graphite raw material to enter. The outlet of the first hopper 130 connects to the inlet of the first screw conveyor 140, continuing to feed the graphite raw material into the first screw conveyor 140. The first screw conveyor 140 can control the feeding speed, transporting the graphite raw material into the mixing unit 200. Meanwhile, the second conveying module mainly consists of a second bucket elevator 150, a second hopper 160, and a second screw conveyor 170. Between the yellow clay raw material storage area and the second bucket elevator 150, a loader 180 transports the yellow clay raw material to the bottom of the second bucket elevator 150. Upon receiving the raw material, the second bucket elevator 150 lifts it to the top, where its upper part connects with the inlet of the second hopper 160, allowing the yellow clay raw material to enter. The outlet of the second hopper 160 connects with the inlet of the second screw conveyor 170, continuing to feed the raw material into the second screw conveyor 170. The second screw conveyor 170 allows for controlled feeding speed, conveying the yellow clay raw material into the mixing unit 200. In this embodiment, by setting up the first screw conveyor 140 and the second screw conveyor 170, the speed at which graphite and yellow clay raw materials are fed into the mixing unit 200 can be freely adjusted, thus facilitating the adjustment of the ratio of the two raw materials to adapt to different production needs.

[0045] The mixing unit 200 is used to thoroughly mix graphite and yellow clay raw materials with water or other additives to form a homogeneous slurry. The mixing unit 200 mainly includes a mixer 210. The upper part of the mixer 210 is roughly cylindrical, and the lower part is roughly conical, thus forming a larger upper inlet for connecting to the outlet ends of the first screw conveyor 140 and the second screw conveyor 170, allowing the graphite and yellow clay raw materials to be fed in together; and a smaller lower outlet for connecting to the extrusion pelletizing unit 300 to output the mixed slurry, preventing splashing. Simultaneously, an industrial water supply pipe 220 is provided on one side of the mixer 210, connecting to its interior, for supplying water and other additives into the mixer 210. Furthermore, a stirring blade 214 is provided inside the mixer 210. The stirring blade 214 is sleeved on one end of the stirring shaft 213 that extends into the mixer 210. The other end of the stirring shaft 213 is connected to the output end of the first motor 212 provided on the upper part of the mixer 210. The first motor 212 drives the stirring shaft 213 and the stirring blade 214 to rotate, so as to fully mix the graphite and yellow clay raw materials inside the mixer 210 with water or other additives to form a uniform slurry.

[0046] The extrusion pelletizing unit 300 is used to extrude, dehydrate, and shape the mixed slurry into mud balls. In this embodiment, the extrusion pelletizing unit 300 mainly includes an extruder 310. The inlet of the extruder 310 is connected to the outlet of the mixer 210, and the outlet of the extruder 310 is connected to the second conveying unit 400. The extruder 310 is generally tubular in structure, capable of extruding the mixed slurry from one end to the other, dehydrating and compacting it, and cutting it into several mud balls at the outlet using a cutter (not shown in the figure). The mud balls then enter the second conveying unit 400. In one or more other embodiments, the extrusion pelletizing unit 300 may also employ a hydraulic device with a mold or other mechanical pressure device, all of which can press the slurry into mud balls of a specified size and shape.

[0047] The second conveying unit 400 is used to receive the mud balls produced by the extrusion pelletizing unit 300 and transport them to a designated location. Then, the mud ball products are manually packed into boxes or pallets for transfer. The second conveying unit 400 mainly includes a belt conveyor 410, one end of which is connected to the discharge port of the extruder 310, and the other end of which is located in the unloading area.

[0048] The control unit is used to automate the entire preparation process and adjust parameters. The control unit is an integrated unit combining multiple PLC controllers and a DCS control system; and it is signal-connected to the first conveying unit 100, the mixing unit 200, the extrusion pelletizing unit 300, and the second conveying unit 400. In this embodiment, the signal connection between the control unit and the first conveying unit 100, the mixing unit 200, the extrusion pelletizing unit 300, and the second conveying unit 400 is a wired electrical connection; in one or more other embodiments, wired fiber optic connection or wireless signal transmission may also be used.

[0049] One specific working method of this embodiment is as follows:

[0050] First, graphite raw materials and yellow clay raw materials are obtained from the raw material storage area by a single-beam overhead crane 110 and a loader, respectively. Then, the graphite raw materials and yellow clay raw materials are transported into the mixer 210 of the mixing unit 200 through the first conveying module and the second conveying module, respectively. In the mixer 210, the graphite raw materials and yellow clay raw materials are mixed with water and other additives to obtain a slurry mixture. Then, the slurry mixture is fed into the extruder 310 of the extrusion pelletizing unit 300, where it is extruded and dehydrated to become mud ball products. Afterward, the mud ball products are transported to the unloading area through the second conveying unit 400 for subsequent loading, unloading and transfer.

[0051] In this embodiment, the mud ball preparation system automatically acquires graphite raw materials and yellow clay raw materials by setting up a first conveying module and a second conveying module, respectively. Then, through a mixing unit 200, an extrusion ball-making unit 300, and a second conveying unit 400 connected in sequence, the mixing of raw materials, the production of mud balls, and the transfer of mud ball products are automatically completed. The entire process is controlled and regulated by a control unit that is connected to the first conveying unit 100, the mixing unit 200, the extrusion ball-making unit 300, and the second conveying unit 400. This achieves efficient and rapid fully automated production, solving the problems of low efficiency, unstable quality, high labor intensity, and difficulty in meeting the needs of large-scale and standardized production in the traditional mud ball preparation method of the prior art, which is mainly based on manual or semi-mechanized operation.

[0052] Furthermore, in the first conveying module of the first conveying unit 100 in this embodiment, a first manual controller 111 is also provided on the drive motor of the single-beam trolley 110, so that manual adjustment can be performed in case of remote signal control failure. A second manual controller 121, a first operating status table 122, and a first current indicator 123 are provided on the drive motor of the first bucket elevator 120, so that the operating status of the first bucket elevator 120 can be comprehensively monitored and timely adjustments can be made. Simultaneously, a first gravity transmitter 131 and a first gravity DCS alarm 132 are installed on the first hopper 130 to monitor the weight of the raw materials inside the first hopper 130. A second operating status meter 141 and a second current indicator 142 are installed on the drive motor of the first screw conveyor 140. The control unit is equipped with an interlock between the drive motor of the first screw conveyor 140 and the first gravity DCS alarm 132. When the weight of the raw materials in the first hopper 130 is too high or too low, the drive motor of the first screw conveyor 140 can be stopped in time. When the weight is too low, the timely stopping of the drive motor can save energy; when the weight is too high, the timely stopping of the drive motor can prevent the drive motor from overloading and protect the system. Furthermore, in the second conveying module, a third manual controller 151, a third operating status meter 152, and a third current indicator 153 are also installed on the drive motor of the second bucket elevator 150, so as to comprehensively monitor the operating status of the second bucket elevator 150 and make timely adjustments. Meanwhile, a second gravity transmitter 161 and a second gravity DCS alarm 162 are also installed on the second hopper 160 to monitor the weight of the raw materials in the second hopper 160; a fourth operating status meter 171 and a fourth current indicator 172 are installed on the drive motor of the second screw conveyor 170; and the control unit is equipped with an interlock between the drive motor of the second screw conveyor 170 and the second gravity DCS alarm 162, so that the drive motor of the second screw conveyor 170 can be stopped in time when the weight of the raw materials in the second hopper 160 is too high or too low.

[0053] Furthermore, in this embodiment, the mixing unit 200 is also equipped with a fourth manual controller 215, a fifth operating status meter 216, and a fifth current indicator 217 on the first motor 212, thereby enabling comprehensive monitoring of the operating status of the mixer 210 and timely adjustments. Additionally, the industrial water delivery pipe 220 is also equipped with a branch pipe section connected to the extruder 310, allowing industrial water to be introduced into the extruder 310 for unblocking or cleaning when needed. Simultaneously, a first ball valve 221 is installed on the main pipe section of the industrial water delivery pipe 220, and a second ball valve 222 and a third ball valve 223 are installed on its branch pipe sections. The first ball valve 221 and the third ball valve 223 respectively control the opening and closing of the main pipe section and the branch pipe section of the industrial water delivery pipe 220, while the second ball valve 222 is used for venting. In addition, a metal rotor flowmeter 224 is installed on the main section of the industrial water conveying pipe 220, and a flow display meter 225 is installed on the metal rotor flowmeter 224 to monitor and regulate the flow of the main section of the industrial water conveying pipe 220 in a timely manner, thereby controlling the amount of water added to the mixer 210 and adjusting the ratio of water and raw materials in a timely manner.

[0054] Furthermore, in the extrusion ball-making unit 300 of this embodiment, a fifth manual controller 311, a sixth operating status table 312 and a sixth current indicator 313 are also provided on the drive motor of the extruder 310, so that the operating status of the extruder 310 can be fully monitored and adjusted in a timely manner.

[0055] Furthermore, such as Figure 5As shown in the diagram, this embodiment also includes a dust collection unit 600. The dust collection unit 600 primarily collects dust from the first conveying unit 100 to prevent dust pollution from materials before mixing during transportation, thus protecting the on-site environment. The dust collection unit 600 mainly includes a dust collector 610, a dust collection fan 620, and a dust collection chimney 630. The dust collector 610's dust collection pipeline 612 has several dust collection inlets, respectively located near the bottom of the first bucket elevator 120, the bottom of the second bucket elevator 150, the inlet of the first hopper 130, and the inlet of the second hopper 160, targeting locations prone to dust generation during raw material transfer. The inlet of the dust collection fan 620 is connected to the dust collector 610 to provide negative pressure for dust collection. Simultaneously, the dust collection chimney 630 is connected to the outlet of the dust collection fan 620 to collect and treat residual dust in the exhaust gas. Furthermore, a first pressure gauge 613 is installed on the dust collection pipeline 612; a second pressure gauge 614 is installed on the pipeline connecting the dust collector 610 and the dust collection fan 620. The first pressure gauge 613 and the second pressure gauge 614 can monitor the negative pressure at the inlet of the dust collector 610 and the dust collection fan 620 in real time, so that timely adjustments can be made in the control unit system when the negative pressure is insufficient, ensuring the stability of dust collection and avoiding environmental pollution caused by negative pressure fluctuations. Next, a sixth manual controller 621, a seventh operating status meter 622, and a seventh current indicator 623 are also installed on the drive motor of the dust collection fan 620, so that the operating status of the dust collection fan 620 can be comprehensively monitored and adjusted in a timely manner. In addition, in one or more other embodiments, the dust collection unit 600 may be omitted, and other methods, such as a spray dust suppression device, may be used instead.

[0056] Furthermore, such as Figure 6As shown in the diagram, this embodiment also includes a wastewater recovery unit 700, which primarily recovers and reuses the wastewater generated by the extrusion pelletizing unit 300. The wastewater recovery unit 700 mainly includes a clarifier 710 and a submersible pump 720. The clarifier 710 is connected to the wastewater discharge pipeline of the extruder 310, used for natural sedimentation of the wastewater to recover residual raw materials. The submersible pump 720 is used to pump the upper clarified liquid from the clarifier 710 and transport it to the rainwater pipe network. Furthermore, a DCS remote controller 721 and a DCS remote operation status table 722 are installed on the drive motor of the submersible pump 720, allowing for comprehensive monitoring of the submersible pump 720's operating status and timely adjustments. Multiple level gauges 711 and multiple level alarms 712 are installed in the clarifier 710 to promptly detect situations where the liquid level in the clarifier 710 is too low or too high, ensuring a stable liquid level in the clarifier 710. Furthermore, the control unit is equipped with an interlock between the DCS remote controller 721 and the liquid level alarm 712. When the liquid level in the clarifier 710 is too low, the submersible pump 720 can be stopped in time to prevent the liquid level from dropping further. Alternatively, in one or more other embodiments, the wastewater recovery unit 700 may be omitted, and wastewater may be reintroduced into the mixing device for reuse instead.
