Description

Technical Field

[0001] This application relates to the technical field of underground filling in mines, and in particular to a cementitious powder production equipment. Background Technology

[0002] Mine backfilling is a crucial part of underground production, and its quality directly affects the safety of the entire mine. Traditional backfilling systems rely on conventional instruments to control the proportion of backfill paste, which involves a lot of human error, high labor intensity for workers, and various degrees of backfilling quality problems.

[0003] The strength and cost of cemented backfill are mainly determined by factors such as the properties of the tailings themselves, the concentration of the backfill slurry, and the selection of cementing materials. Therefore, it is crucial to conduct in-depth research on different types of tailings and select appropriate cementing materials. Furthermore, as the backfilling process changes, the formulation of the cementing powder must also be adjusted to improve the quality of the backfill.

[0004] After the change in mine backfilling process, the backfill particles are significantly finer. Currently, the cementing materials used for mine backfilling are mainly gypsum, cement, and slag. In the current production technology, the cementing material preparation device uses sensors to monitor the concentration of the material in the feed hopper and compares it with a preset value. If the concentration is higher than the preset value, water is added; if the concentration is lower than the preset value, more material is added. This cycle continues until the concentration of the material in the feed hopper meets the expected concentration requirement, at which point it is stirred and mixed before backfilling. Therefore, the preparation device for cementing materials in the existing technology has a long preparation cycle and cannot quickly achieve effective cementation of fine-particle tailings paste. Summary of the Invention

[0005] In view of this, this application provides a cementitious powder production equipment to solve the problem that existing cementitious material preparation devices have long preparation cycles and cannot quickly achieve effective cementation of fine-particle paste tailings.

[0006] This application provides a cementitious powder production apparatus, comprising: The material weighing assembly includes a first weighing bin, which is used to acquire a set weight of material. The first screw conveyor is used to transport the material in the first weighing bin to the mixing bin; The first pneumatic conveyor is used to transport materials in the mixing bin to the first belt conveyor; The first belt conveyor is used to transport the material on it to the weighing belt; The weighing belt is used to transport the material on it to the second belt conveyor; The second belt conveyor is used to transport the materials on it to the finished product warehouse.

[0007] By adopting the above technical solution, the material weighing component can obtain the set weight of material, ensuring the accuracy of the amount of material input into production; the first screw conveyor transports the material to the mixing bin for subsequent material mixing processing; the first pneumatic conveyor transports the material in the mixing bin to the first belt conveyor for further material transfer; the first belt conveyor transports the material to the weighing belt, which then transports the material to the second belt conveyor, and finally the second belt conveyor transports the material to the finished product bin. The entire process realizes the orderly transportation of materials from acquisition to final storage as finished products. This cementitious powder production equipment can directly obtain the weight of the material before mixing and the weight of the material after mixing, and can quickly achieve the proportion of each material in the cementitious powder without multiple adjustments. This enables rapid and effective cementation of fine-grained paste tailings, meeting the filling strength requirements of fine-grained tailings and improving the quality of the filling body.

[0008] Preferably, the first weighing bin includes: The first compartment has a feed inlet at the top and a discharge outlet at the bottom; The first gate is hinged to the inner wall of the first chamber and is used to block the discharge port; The first hydraulic cylinder is hinged to the first gate and the first chamber body respectively, and is used to open or close the first gate.

[0009] By adopting the above technical solution, the first chamber of the first weighing chamber is fed through the inlet and discharged through the outlet. The first gate is hinged to the first chamber. The first hydraulic cylinder can control the opening and closing of the first gate to control the timing of the material in the first chamber being discharged from the outlet.

[0010] Preferably, the first weighing bin further includes a first weighing sensor, which is disposed on the top of the first gate and is used to obtain the weight of the material inside the first bin.

[0011] By adopting the above technical solution, the material weighing component can obtain the set weight of material. The first hopper stores the material. A first weighing sensor is set on the top of the first gate to accurately obtain the weight of the material in the first hopper. The opening and closing of the discharge port is controlled by the first gate and the first hydraulic cylinder to deliver the set weight of material to the mixing hopper, thereby satisfying the requirement of delivering the set proportion of material to the mixing hopper.

[0012] Preferably, it also includes a buffer component, which comprises: A buffer chamber is located between the weighing belt and the second belt conveyor; The conveyor track is located above the buffer chamber, with one end hinged to the support of the second belt conveyor and the other end being a free end; The second hydraulic cylinder is hinged to the support of the conveying track and the second belt conveyor respectively. The second hydraulic cylinder can drive the free end to connect with the weighing belt, or the free end to separate from the weighing belt. The material on the weighing belt is conveyed to the second belt conveyor after passing through the conveying track.

[0013] By adopting the above technical solution, when the cementitious powder production equipment is working normally, the second hydraulic cylinder connects its free end to the weighing belt, and the material on the weighing belt is conveyed to the second belt conveyor after passing through the conveying track. When the cementitious powder production equipment malfunctions and stops, the second hydraulic cylinder separates its free end from the weighing belt, and the weighing belt conveyor conveys the material on it to the buffer bin, avoiding blockages caused by the material being continuously conveyed by the second belt conveyor. By setting up the buffer bin, the second hydraulic cylinder, and the conveying track, stable material conveying is maintained.

[0014] Preferably, the buffer assembly further includes a second pneumatic conveyor for conveying the material in the buffer chamber to the mixing chamber.

[0015] By adopting the above technical solution, the second pneumatic conveyor can transport the material in the buffer bin to the mixing bin again, avoiding excessive material accumulation in the buffer bin. In addition, when the material on the weighing belt is not mixed evenly, the material on the weighing belt can be transported to the buffer bin, and then from the buffer bin to the mixing bin for further mixing.

[0016] Preferably, it also includes a screw mixer, installed on the mixing chamber, for stirring the materials in the mixing chamber.

[0017] By adopting the above technical solution, the material in the mixing chamber is stirred by the spiral mixer installed on the mixing chamber, which can make the material mix more evenly. Then the material is transported to the finished product silo in sequence by the first pneumatic conveyor, the first belt conveyor, the weighing belt, and the second belt conveyor, which can ensure that the quality of the material entering the finished product silo is better.

[0018] Preferably, it also includes a first striking component, which comprises: The first housing is fixedly connected to the outer wall of the material conveying pipe of the first pneumatic conveyor; The first electromagnet is fixedly connected to the inner wall of the first housing. The first armature is disposed opposite to the first electromagnet and is slidably connected to the inner wall of the first housing; The first spring has its two ends fixedly connected to the inner wall of the first housing and the first armature, respectively.

[0019] By adopting the above technical solution, the first weighing bin of the material weighing component can obtain the material of a set weight. The first screw conveyor transports the material from the first weighing bin to the mixing bin. The first pneumatic conveyor then transports the material in the mixing bin to the first belt conveyor. After that, the material is transported sequentially through the first belt conveyor, the weighing belt, and the second belt conveyor to the finished product bin. At the same time, the first housing of the first striking component is fixedly connected to the outer wall of the conveying pipe of the first pneumatic conveyor. When the first electromagnet is energized and attracts the first armature, and when the first armature is reset by the first spring after de-energization, it can strike the conveying pipe to prevent the material from blocking the conveying pipe and ensure smooth material conveying.

[0020] Preferably, it also includes a second striking component, which comprises: The second housing is fixedly connected to the outer wall of the conveying pipe of the second pneumatic conveyor; The second electromagnet is fixedly connected to the inner wall of the second housing. The second armature is disposed opposite to the second electromagnet and is slidably connected to the inner wall of the second housing; The second spring has its two ends fixedly connected to the inner wall of the second housing and the second armature, respectively.

[0021] By adopting the above technical solution, the first weighing bin of the material weighing component can obtain the material of a set weight, which is then conveyed to the mixing bin by the first screw conveyor, and then to the first belt conveyor by the first pneumatic conveyor. Afterwards, it is conveyed sequentially to the finished product bin via the weighing belt and the second belt conveyor. The first gate and the first hydraulic cylinder of the first weighing bin work together to control the opening and closing of the discharge port, and the first weighing sensor can obtain the weight of the material in the first bin. The buffer bin of the buffer component is located between the weighing belt and the second belt conveyor. The conveying track and the second hydraulic cylinder work together to convey the material from the weighing belt to the second belt conveyor, and the second pneumatic conveyor can convey the material in the buffer bin back to the mixing bin. The screw mixer can agitate the material in the mixing bin. The first striking component can act on the conveying pipe of the first pneumatic conveyor. A second striking component is added; when the second electromagnet is energized, it attracts the second armature to compress the second spring. When the power is off, the second armature, under the action of the second spring, strikes the second housing and the connected conveying pipe of the second pneumatic conveyor, preventing material from accumulating and blocking in the conveying pipe of the second pneumatic conveyor, and ensuring smooth material conveying.

[0022] Preferably, the material weighing assembly also includes a second screw conveyor and a third screw conveyor. The material weighing assembly further includes a second weighing bin and a third weighing bin. The second screw conveyor is used to transport the material in the second weighing bin to the mixing bin, and the third screw conveyor is used to transport the material in the third weighing bin to the mixing bin.

[0023] By adopting the above technical solution, adding a second screw conveyor, a third screw conveyor, a second weighing bin, and a third weighing bin, the weighing acquisition methods and conveying channels for materials can be increased. This enables the independent weighing and separate conveying of various materials, thereby improving the diversity and flexibility of material supply in the production process of cementitious powder and helping to produce cementitious powder products that better meet the needs.

[0027] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0031] This application discloses a cementitious powder production equipment, such as... Figures 1 to 4 As shown, the system includes a material weighing assembly, a first screw conveyor 201, a first pneumatic conveyor 300, a first belt conveyor 401, a weighing belt 402, a second belt conveyor 403, a mixing silo 104, and a finished product silo 105. After the material weighing assembly acquires a set weight of material, the first screw conveyor 201 transports the material to the mixing silo 104. The first pneumatic conveyor 300 then transports the material from the mixing silo 104 to the first belt conveyor 401. The first belt conveyor 401 then transports the material to the weighing belt 402, which in turn transports the material to the second belt conveyor 403. Finally, the second belt conveyor 403 transports the material to the finished product silo 105. This series of conveying processes is carried out in an orderly manner, efficiently completing the production and conveying process of the adhesive powder and improving production efficiency.

[0032] Specifically, the material weighing assembly includes a first weighing chamber 101. For example... Figure 4As shown, the first weighing chamber 101 includes a first chamber body 1011, a first gate 1012, and a first hydraulic cylinder 1013. The first chamber body 1011 has a feed inlet 10111 at its top for easy material entry and a discharge outlet 10112 at its bottom for material discharge. The first chamber body 1011 is generally made of a robust and durable metal material and is typically cylindrical or cuboid in shape to ensure sufficient capacity for material storage. The first gate 1012 is hinged to the inner wall of the first chamber body 1011 and can block the discharge outlet 10112. The first gate 1012 can be a flat plate structure, rotating through a hinge point with the inner wall of the first chamber body 1011 to control the opening and closing of the discharge outlet 10112. The first hydraulic cylinder 1013 is hinged to both the first gate 1012 and the inner wall of the first chamber body 1011, and is used to open or close the first gate 1012. When the piston rod of the first hydraulic cylinder 1013 extends or retracts, it drives the first gate 1012 to rotate around the hinge point, thereby opening and closing the discharge port 10112. The first hydraulic cylinder 1013 can also be replaced by an electric push rod or similar device, which can still drive the first gate 1012. The first weighing bin 101 also includes a first weighing sensor 1014, which is located on top of the first gate 1012. It can acquire the weight of the material inside the first bin 1011 in real time. The first weighing sensor 1014 typically uses a piezomagnetic force gauge, which can accurately measure the weight of the material. When the material inside the first bin 1011 reaches the set weight, a signal is transmitted to the control unit, which can be a central control platform, a host computer, a computer, or a microcontroller.

[0033] After the material is weighed in the first weighing bin 101, the first screw conveyor 201 begins operation. The first screw conveyor 201 consists of a screw shaft, screw blades, and a casing. The screw shaft is typically a metal shaft with screw blades welded to its surface. The screw blades are arranged in a spiral pattern, and when the screw shaft rotates, the material is conveyed forward along the screw blades. The casing is generally a cylindrical structure, serving to protect and guide the material. The first screw conveyor 201 transports the material from the first weighing bin 101 to the mixing bin 104, allowing the material to be mixed centrally.

[0034] A screw mixer is also installed inside the mixing chamber 104. The screw mixer mainly consists of a stirring shaft, stirring blades, and a drive motor. The stirring shaft is vertically installed inside the mixing chamber 104, and the stirring blades are fixed on the stirring shaft. The drive motor drives the stirring shaft to rotate, causing the stirring blades to stir the material inside the mixing chamber 104. Through stirring, the material can be fully and evenly mixed, preparing it for subsequent transportation. The mixed material is conveyed to the first belt conveyor 401 via the first pneumatic conveyor 300. The first pneumatic conveyor 300 uses the power of airflow to transport the material and includes a conveying pipe and a blower. The conveying pipe connects the mixing chamber 104 and the first belt conveyor 401, and the airflow generated by the blower blows the material from the mixing chamber 104 onto the first belt conveyor 401. To prevent material from clogging in the conveying pipe, a first striking assembly is also provided. The first striking assembly includes a first housing, a first electromagnet, a first armature, and a first spring. The first housing is fixedly connected to the outer wall of the conveying pipe of the first pneumatic conveyor 300, generally by welding. The first electromagnet is fixedly connected to the inner wall of the first housing and generates magnetism when energized. The first armature is positioned opposite the first electromagnet and is slidably connected to the inner wall of the first housing. The two ends of the first spring are fixedly connected to the inner wall of the first housing and the first armature, respectively. When the first electromagnet is energized, it attracts the first armature, and the first spring is stretched. When the first electromagnet is de-energized, the first armature strikes the first housing under the action of the first spring, thereby causing the conveying pipe to vibrate and preventing material blockage. The first belt conveyor 401 consists of a conveyor belt, two pulleys spaced apart, and a drive device. The conveyor belt is wound around the two pulleys. The drive device can be a servo motor, which is electrically connected to the control unit. The drive device is connected to one of the pulleys, and drives the pulley to rotate, thereby making the conveyor belt run and conveying the material to the weighing belt 402. The weighing belt 402 also consists of a conveyor belt, two spaced pulleys, and a drive unit. Its belt drive structure is the same as that of the first belt conveyor 401, and will not be described again here. The weighing belt 402 is equipped with a weighing sensor; specifically, it is an electronic belt scale that can continuously weigh the materials on it. The weighing belt 402 can monitor the weight of the materials on the belt in real time to ensure that the weight meets the requirements. The weighed material is then conveyed by the weighing belt 402 to the second belt conveyor 403, and finally to the finished product silo 105. The finished product silo 105 is used to store the produced adhesive powder. Its structure can be designed according to actual needs, but generally, it must be well-sealed to prevent the material from getting damp.

[0035] The implementation principle of this embodiment is as follows: This cementitious powder production equipment accurately weighs the material through a material weighing component, and achieves efficient production of cementitious powder through multiple conveying links and mixing processes. The collaborative work of each component reduces human interference and improves the degree of automation in production. In particular, the spiral mixer and the percussion component ensure thorough mixing of the material, while the latter prevents blockage during conveying, significantly shortening the cementitious powder preparation cycle and improving production efficiency and product quality, representing a significant improvement over existing technologies.

[0036] like Figure 1 and 3As shown, the cementitious powder production equipment provided in this embodiment also includes a buffer assembly, which includes a buffer bin 501, a conveyor track 502, a second hydraulic cylinder 503, and a second pneumatic conveyor 504. The buffer bin 501 is located between the weighing belt 402 and the second belt conveyor 403, and is used to temporarily store materials, serving a buffering and regulating function. The buffer bin 501 is generally made of metal and has a certain capacity. The conveyor track 502 is located above the buffer bin 501, with one end hinged to the support of the second belt conveyor 403 and the other end being a free end. The conveyor track 502 is usually inclined to facilitate material sliding. The second hydraulic cylinder 503 is hinged to both the conveyor track 502 and the support of the second belt conveyor 403. The second hydraulic cylinder 503 can drive the free end to connect with or separate from the weighing belt 402. When the piston rod of the second hydraulic cylinder 503 extends, its free end connects to the weighing belt 402, allowing material to be conveyed to the second belt conveyor 403 via the conveying track 502. When the piston rod of the second hydraulic cylinder 503 retracts, its free end separates from the weighing belt 402. During normal operation of the cementitious powder production equipment, the second hydraulic cylinder 503 connects its free end to the weighing belt 402, and the material on the weighing belt 402 is conveyed to the second belt conveyor 403 via the conveying track 502. When the cementitious powder production equipment malfunctions and stops, the second hydraulic cylinder 503 separates its free end from the weighing belt 402, and the weighing belt 402 conveys the material to the buffer chamber 501, preventing blockages caused by continuous material conveying via the second belt conveyor 403. By setting up the buffer chamber 501, the second hydraulic cylinder 503, and the conveying track 502, stable material conveying is maintained. The structure of the second pneumatic conveyor 504 is similar to that of the first pneumatic conveyor 300, also including a conveying pipe and a blower, which will not be described in detail here. To prevent blockage of the conveying pipe of the second pneumatic conveyor 504, a second striking assembly is also provided. The second striking assembly includes a second housing, a second electromagnet, a second armature, and a second spring. Its working principle is the same as the first striking assembly; the electromagnet's on / off state controls the armature to strike the housing, causing the conveying pipe to vibrate and preventing material blockage. The buffer assembly makes the production process of the cementitious powder more flexible and stable. The buffer chamber 501 can adjust the material conveying speed, avoiding production stoppages caused by speed mismatch between preceding and following processes. The second pneumatic conveyor 504 transports the material in the buffer chamber 501 back to the mixing chamber 104, realizing material recycling and improving resource utilization. Simultaneously, the second striking assembly ensures smooth material conveying within the conveying pipe of the second pneumatic conveyor 504, further improving production efficiency and product quality, offering significant advantages compared to existing technologies.

[0037] like Figure 1 and 2As shown, the cementitious powder production equipment provided in this embodiment includes a second weighing chamber 102 and a third weighing chamber 103 as its material weighing components, as well as a second screw conveyor 202 and a third screw conveyor 203. The second screw conveyor 202 is used to transport the material in the second weighing chamber 102 to the mixing chamber 104, and the third screw conveyor 203 is used to transport the material in the third weighing chamber 103 to the mixing chamber 104. The structures of the second weighing chamber 102 and the third weighing chamber 103 are similar to those of the first weighing chamber 101, and will not be described in detail here. The structures of the first weighing chamber 101, the second weighing chamber 102, and the third weighing chamber 103 are capable of accurately weighing different materials. The structures of the second screw conveyor 202 and the third screw conveyor 203 are the same as those of the first screw conveyor 201, both consisting of a screw shaft, screw blades, and a casing, respectively transporting the material in their respective weighing chambers to the mixing chamber 104. By adding multiple weighing hoppers and screw conveyors, various materials can be weighed simultaneously and transported to mixing hopper 104 for mixing, enriching the formulation of the cementitious powder and improving its quality and performance. The setup of multiple weighing hoppers and screw conveyors allows for the mixing of various materials in cementitious powder production, enabling adjustments to the formulation according to different needs. The thorough mixing of different materials in mixing hopper 104 allows each material to leverage its own advantages, resulting in cementitious powder of higher quality and superior performance. This diversified production method meets the cementitious powder requirements of different mine filling processes, offering greater adaptability and market competitiveness compared to cementitious powder produced from a single material.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
