Description

Technical Field

[0001] This utility model relates to the field of cement production equipment technology, specifically a cement production conveying device. Background Technology

[0002] In the cement production process, the conveying of cement or cement raw materials is a crucial step. Traditionally, screw conveyors are the primary method of conveying; however, existing screw conveyors have several problems. Taking utility model patent CN202320773031.5 as an example, this patent discloses a cement screw conveyor with a dust removal structure. While this conveyor solves problems such as dust generation during cement input and cement ash clogging in the input device through a dust removal unit and a vibration unit, its conveying distance is limited and cannot meet the needs of ultra-long-distance conveying.

[0003] In actual cement production, especially in large cement plants or construction sites, it is often necessary to transport cement or cement raw materials from one distant location to another. Existing screw conveyors, due to their structural limitations, struggle to achieve continuous transport over extremely long distances. Furthermore, existing screw conveyors are prone to insufficient power and low conveying efficiency during long transport distances. When driving long screw blades over long distances, the motor often becomes overloaded, leading to insufficient motor power and affecting conveying efficiency. Simultaneously, the lack of effective support and sealing structures in existing screw conveyors makes them susceptible to material leakage and dust spillage, resulting in material waste and environmental pollution.

[0004] In order to solve the above-mentioned problems in the existing technology, this utility model proposes a cement production conveying device. Through innovative design, it achieves technical effects such as ultra-long distance conveying, improved conveying efficiency, and prevention of material leakage and dust spillage.

[0015] (III) Beneficial Effects This utility model provides a cement production conveying device, which has the following beneficial effects: 1. By using a series of pipe components, ultra-long-distance conveying of cement or cement raw materials can be achieved. The conveying distance is extended by utilizing individual pipe segment assemblies. A drive assembly is installed at each pipe segment assembly to achieve segmented conveying; each segment is conveyed continuously, ultimately achieving ultra-long-distance conveying. Compared with existing technologies, this extends the conveying length of traditional screw conveyors. Simultaneously, this pipeline conveying method enables closed-loop conveying of cement or cement raw materials, avoiding the generation of large amounts of dust during conveying and preventing or reducing air pollution. Specifically, each first pipe body and each connecting pipe are arranged alternately to form an ultra-long conveying pipeline. Each pipe segment assembly is equipped with a drive assembly, ensuring that each pipe segment can be driven independently, avoiding insufficient power due to excessive conveying distance. Furthermore, by rationally designing the length and number of pipe segment assemblies, the conveying distance can be flexibly adjusted according to actual needs to meet the conveying requirements of different scenarios.

[0016] 2. This utility model significantly improves conveying efficiency and effectively prevents material leakage and dust spillage by optimizing the design of the drive and support components. First, the motor in the drive component is connected to the rotating shaft via a reducer and transmission shaft. This transmission method ensures that the motor's power is efficiently transmitted to the rotating shaft, driving the spiral blades to rotate and convey the material. Compared with existing technologies, this transmission method better adapts to the needs of long-distance conveying and avoids insufficient power due to excessive motor load. Second, the design of the support component provides stable support for the rotating shaft, ensuring its stability during high-speed rotation and thus improving conveying efficiency. The combined use of the support plate, first support column, second support column, and bearings effectively distributes the load on the rotating shaft, reduces wear, and extends the equipment's service life. Furthermore, the protective cover and rubber sealing strip effectively prevent material leakage and dust spillage. The protective cover protects the rotating shaft and support components from external environmental influences, while the rubber sealing strip ensures a tight seal between the rotating shaft and the protective cover, preventing material leakage from gaps. This sealing design not only reduces material waste but also minimizes environmental pollution, meeting environmental protection requirements. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0022] Please see Figures 1 to 7 The present invention provides a technical solution: a cement production conveying device, including a pipe string component and a feed hopper 3, wherein the feed hopper 3 is fixedly installed at one end of the pipe string component.

[0023] The pipe string component includes multiple pipe segment assemblies and multiple drive assemblies. The pipe segment assemblies are arranged sequentially and fixedly installed. The pipe segment assemblies are connected sequentially to form a long conveying channel.

[0024] The pipe segment assembly includes a first pipe body 1 and a connecting pipe 4, with the connecting pipe 4 fixedly installed at one end of the first pipe body 1.

[0025] The drive assembly is mounted on the pipe section assembly.

[0026] The drive assembly includes a motor 6 and a conveyor. The conveyor is rotatably installed inside the first pipe body 1, and the motor 6 is fixedly installed on the outer side wall of the connecting pipe 4. The motor 6 is connected to the conveyor for transmission, and the motor 6 drives the conveyor to rotate.

[0027] This technical solution enables ultra-long-distance transportation of cement or cement raw materials through the arrangement of pipe string components. The transportation distance is extended by utilizing individual pipe segment components, and segmented transportation is achieved by setting a drive component at each pipe segment component; continuous transportation of each segment ultimately achieves the goal of ultra-long-distance transportation. Compared with existing technologies, this extends the transportation length of the drive screw conveyor; at the same time, this pipeline transportation method enables closed-loop transportation of cement or cement raw materials, avoiding the generation of large amounts of dust during transportation and preventing or reducing air pollution.

[0028] In the entire device, each first pipe body 1 and each connecting pipe 4 are arranged alternately in sequence to form an ultra-long conveying pipeline.

[0029] The feed hopper 3 is fixed at one end of the pipe string component and serves as the input inlet for cement materials. It can conveniently receive external materials, prevent materials from scattering during feeding, provide a stable source for the material conveying of the pipe string component, and ensure a smooth start to the conveying process.

[0030] The pipe string component includes multiple pipe segment assemblies and a drive assembly. The pipe segment assemblies are arranged in sequence and fixed and connected to form a long conveying channel, which can meet the needs of long-distance conveying and solve the problem of short conveying distance in existing devices. The drive assembly provides power for conveying and ensures that the material moves continuously in the channel.

[0031] In the pipe segment assembly (first pipe body 1, connecting pipe 4), the first pipe body 1 is the main channel for material conveying and accommodates the operation of the conveying components; the connecting pipe 4 is fixed at one end of the first pipe body 1, which not only realizes the connection between adjacent pipe segment assemblies and ensures the continuity of the channel, but also provides an installation carrier for the motor 6, so that the drive assembly can be stably assembled.

[0032] In the drive assembly (motor 6, conveyor), motor 6 provides power for conveying; the conveyor is driven to rotate by motor 6, and the rotational force pushes the material to move along the first tube 1, thereby achieving efficient material conveying.

[0033] Specifically, the two ends of the first tube 1 are respectively inserted into the two connecting tubes 4, and the first tube 1 and the connecting tubes 4 are fixedly installed.

[0034] The fixing and installation between the first pipe body 1 and the connecting pipe 4 includes, but is not limited to, detachable installation, fixed connection, welding and other installation methods. Bolts can also be used for fixing as needed. The insertion and fixing of the first pipe body 1 and the connecting pipe 4 not only ensures a tight and leak-proof connection of the pipe section components, but also facilitates disassembly and maintenance, ensuring the stability of the long conveying channel.

[0035] More specifically, the conveying component includes a rotating shaft 12 and a helical blade 16, with the helical blade 16 mounted on the outer side wall of the rotating shaft 12 and the two fixedly connected.

[0036] The rotating shaft 12 drives the fixed set of spiral blades 16 to rotate, and the spiral structure pushes the material to move, so as to realize the stable conveying of cement in the first pipe body 1.

[0037] More specifically, the drive assembly also includes a reducer 5 and a drive shaft 14. The reducer 5 is fixedly mounted on the connecting pipe 4, and the motor 6 is fixedly mounted on the reducer 5. The output shaft of the motor 6 is fixedly mounted on the power input end of the reducer 5, and the power output end of the reducer 5 is fixedly mounted coaxially with the drive shaft 14. The drive shaft 14 is connected to the rotating shaft 12 for transmission, and the drive shaft 14 drives the rotating shaft 12 to rotate.

[0038] The reducer 5 is fixed to the connecting pipe 4, providing a stable mounting base for the motor 6; the output shaft of the motor 6 is connected to the input end of the reducer 5. After the reducer 5 adjusts the power, it is transmitted to the rotating shaft 12 through the coaxially fixed transmission shaft 14, realizing power adaptation and stable transmission, and ensuring the efficient operation of the conveying component.

[0039] More specifically, the power output end of the drive shaft 14 is fitted with a second bevel gear 15 and the two are fixedly connected, and one end of the rotating shaft 12 is fitted with a first bevel gear 13 and the two are fixedly connected, with the first bevel gear 13 meshing with the second bevel gear 15.

[0040] The second bevel gear 15 meshes with the first bevel gear 13 for transmission; this structure realizes the conversion of power direction, ensures that power is stably transmitted to the rotating shaft 12, ensures the continuous operation of the conveyor, and improves the reliability of the drive.

[0041] More specifically, a support assembly is fixedly installed inside the connecting pipe 4. The support assembly includes a support plate 8, a first support column 9, and a second support column 10. The support plate 8 is fixedly installed on the inner wall of the connecting pipe 4. The first support column 9 and the second support column 10 are both fixedly installed on the support plate 8. Bearings 11 are fixedly installed on the first support column 9 and the second support column 10. The end of the rotating shaft 12 passes through the bearing 11, and the rotating shaft 12 is rotatably mounted to the first support column 9 or the second support column 10 through the bearing 11.

[0042] The support plate 8 provides a stable foundation for the first support column 9 and the second support column 10. The bearings 11 on the first support column 9 and the second support column 10 support the rotating shaft 12, converting sliding friction into rolling friction, reducing resistance, ensuring smooth and efficient rotation of the rotating shaft, and improving equipment stability. The transmission shaft 14 passes through the support plate 8.

[0043] More specifically, the support assembly also includes a protective cover 7, which is fixedly mounted on the support plate 8, with the end of the rotating shaft 12 penetrating through the side wall of the protective cover 7. A rubber sealing strip is installed on the side wall of the protective cover 7 near the penetration point of the rotating shaft 12.

[0044] The protective cover 7 can enclose the precision components inside the support assembly, preventing cement dust from entering and causing wear, and protecting the components to extend their service life; the rubber sealing strip at the through-hole fits tightly against the rotating shaft 12, further enhancing the sealing performance, preventing dust leakage, reducing material waste and ensuring environmental cleanliness; preventing cement or cement raw materials from entering the protective cover 7, and avoiding interference with the transmission located inside the protective cover 7.

[0045] Specifically, a second tube body 2 is fixedly installed at one end of the tube string component and the two are connected, and a feed hopper 3 is fixedly installed on the second tube body 2 and the two are connected.

[0046] The second pipe body 2 is fixed to one end of the pipe string component and connected to it, forming a connecting bridge between the pipe string component and the feed hopper 3, ensuring a continuous material conveying channel. The feed hopper 3 is fixed to the second pipe body 2 and connected to it, facilitating the receipt of external cement materials, preventing spillage during feeding, and ensuring smooth operation at the beginning of the conveying process.

[0047] The connecting pipe 4 consists of a pipe body 401 and a mounting part 402. The mounting part 402 is a hollow quadrangular prism, and the reducer 5 is fixedly mounted on the mounting part 402 of the connecting pipe 4. The mounting part 402 serves as the mounting platform for the reducer 5, providing a stable mounting foundation.

[0048] Note that in actual implementation, all components in the drive assembly should be of the same size to avoid discontinuous transmission due to size differences and material conveying blockages caused by transmission imbalance. Motor 6 may include, but is not limited to, a servo motor or a stepper motor. All motors 6 should start synchronously and run at the same speed. Specifically, a programmable logic controller (PLC) can be used for overall control to ensure synchronous start and speed of all motors 6; details will not be elaborated here.

[0049] In use, the operator pours the cement material to be conveyed into the feed hopper 3. Since the feed hopper 3 is connected to the second pipe body 2, and the second pipe body 2 is connected to the pipe string component, the material slides along the inner wall of the feed hopper 3 into the second pipe body 2, and then smoothly enters the long conveying channel of the pipe string component, completing the initial material introduction.

[0050] The motor 6 installed on the connecting pipe 4 is started. The motor 6 outputs power to the reducer 5. After the reducer 5 adjusts the speed and torque of the power, it transmits the power to the coaxially fixed transmission shaft 14. The transmission shaft 14 drives the rotating shaft 12 to rotate through the meshing of the second bevel gear 15 at the end with the first bevel gear 13 at the end of the rotating shaft 12.

[0051] The rotating shaft 12 rotates smoothly under the stable support of the support components (support plate 8, first support column 9, second support column 10, bearing 11) inside the connecting pipe 4. The spiral blades 16 fixed on its outer wall rotate synchronously. Using the thrust of the spiral structure, the cement material in the first pipe body 1 is continuously pushed forward along the long conveying channel of the pipe string component to achieve long-distance conveying.

[0052] During the conveying process, the protective cover 7 prevents cement dust from entering the precision components inside the support assembly. The rubber sealing strip further prevents dust from leaking from the point where the rotating shaft 12 passes through the protective cover 7 or entering the support assembly. At the same time, each pipe section assembly is fixedly connected to the first pipe body 1 and the connecting pipe 4 to ensure that the conveying channel is sealed and stable until the material is output from the other end of the pipe string assembly, completing the entire conveying process.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
