Description

Technical Field

[0001] This utility model belongs to the field of tube mill technology, and in particular relates to a tube mill compartment device with adjustable ventilation efficiency. Background Technology

[0002] In the cement production process, the tube mill is a key piece of equipment, and its performance directly affects the cement output and quality. The tube mill is usually divided into multiple chambers, each equipped with different grinding media (such as steel balls, steel forgings, ceramic balls, etc.) to meet the material grinding needs at different stages.

[0003] However, the compartmentalization device of traditional tube mills has many shortcomings, especially in terms of ventilation efficiency;

[0004] Traditional tube mill compartment devices mostly use double-layer or single-layer compartment plates. While double-layer compartment plates can control the material flow rate to a certain extent, they often lead to uneven airflow distribution. For example, the airflow in the steel ball compartment and the steel forging compartment is insufficient, while the airflow in the ceramic ball compartment is too fast. This not only affects the grinding effect, but also easily causes problems such as dust emission from the grinding head and blockage of the compartment plate grate. On the other hand, although single-layer compartment plates have a simple structure, the material flow rate is too fast and the grinding time is insufficient, resulting in increased circulating load, reduced output, and increased power consumption. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the prior art by providing a tube mill compartment device with flexibly adjustable ventilation efficiency.

[0006] To achieve the above objectives, the utility model employs the following technical solution: a tube mill compartment device with flexibly adjustable ventilation efficiency, comprising a plate frame installed on the tube mill, an inner ring sleeve on the plate frame, a plurality of mounting frames between the plate frame and the inner ring sleeve, a partition plate on each mounting frame, the partition plate dividing the mounting frame into two compartments, namely a first placement compartment and a second placement compartment, a plurality of crossbeams on the inner sides of the first placement compartment and the second placement compartment, a threaded column installed on the middle crossbeam, a grate plate connecting to the threaded column on the inner side of the mounting frame, a pressure plate on the threaded column for limiting and fixing the grate plate, and a ventilation screen plate on the inner ring sleeve.

[0007] By adopting the above technical solution, this device, through its unique design, allows for flexible adjustment of the ventilation efficiency inside the tube mill, thereby optimizing the material flow rate and grinding effect within the mill. This design improves grinding efficiency, reduces energy consumption, and extends the service life of the equipment.

[0008] Optionally, each of the mounting frames is provided with a pair of mounting seats, and each pair of mounting seats is provided with a mounting hole, which is connected to the plate frame by fixing bolts.

[0009] By adopting the above technical solution, the design of the mounting base and fixing bolts enables the mounting frame to be firmly fixed on the plate frame, ensuring the stability and reliability of the entire compartment device. At the same time, this connection method is also easy to disassemble and replace, reducing maintenance costs.

[0010] Optionally, some of the beams and partitions are arc-shaped, and a pair of positioning posts are installed on each of the beams and partitions, with the pair of positioning posts being symmetrically distributed.

[0011] By adopting the above technical solutions, the arc-shaped crossbeam and partition design can better adapt to the internal shape of the tube mill, reduce friction and wear, and the addition of positioning columns ensures the accuracy of the grate plate pressure plate during installation, preventing them from shifting or deforming.

[0012] Optionally, a threaded cylinder is connected to the end of the threaded column away from the middle crossbeam, and the outer side of the threaded cylinder is provided with anti-slip texture.

[0013] By adopting the above technical solution, the design of the threaded column and threaded cylinder makes it easy to install and disassemble the grate plate. At the same time, by rotating the threaded cylinder, the grate plate can be easily installed and disassembled, and the anti-slip texture design makes the rotation operation simpler and more reliable.

[0014] Optionally, the grate component includes a first grate and a second grate, the first grate and the second grate are respectively located in the first placement chamber and the second placement chamber, and the first grate and the second grate are provided with a plurality of grate holes, which are equidistantly distributed.

[0015] By adopting the above technical solutions, the design of the grate plate can be adjusted to single or double layers according to actual needs, providing more options for different grinding stages. At the same time, the grate holes opened on the grate plate can precisely adjust the flow rate of materials in the mill, meeting the specific requirements of different materials for the grinding environment.

[0016] Optionally, the pressure plate is provided with a connecting hole and a positioning hole on the first grate plate and the second grate plate respectively, and the position of the connecting hole is aligned with the threaded post.

[0017] By adopting the above technical solution, the pressure plate is designed to limit and fix the grate plate, ensuring that the grate plate will not shift or fall off during rotation and adjustment. The setting of the connecting hole and positioning hole realizes the reliable connection and fixation between the pressure plate and the threaded column.

[0018] Optionally, there are two ventilation screens, each connected to the inner ring sleeve. A pair of fixed seats are provided on the ventilation screen, and a handle is installed between the pair of fixed seats.

[0019] By adopting the above technical solution, the design of the ventilation screen plate enhances the ventilation efficiency of the compartment device. At the same time, the double-layer structure makes the ventilation screen plate more robust and durable, and the setting of the fixed base and handle makes it easy for operators to take the upper ventilation screen plate.

[0020] Optionally, the plate frame can be detached from the inner ring sleeve by fixing bolts, or the inner ring sleeve can be connected to the plate frame by stiffening plates. There are several stiffening plates, and the several stiffening plates are arranged in a ring array with the center point of the inner ring sleeve as the base point. The mounting frame is between two of the stiffening plates.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This device divides the interior of the tube mill into multiple independent chambers through the design of several mounting frames and partitions. Each chamber can be flexibly arranged according to actual needs. This design allows for precise control of the material flow rate within the mill, thus achieving a reasonable match between the material and the ceramic balls. When the airflow of the mill tail blower remains constant, adjusting the structure and layout of the partition device ensures a more uniform airflow distribution within each chamber, avoiding the uneven airflow distribution problem that may occur with traditional double-layer partition plates; 2. The grate components and threads in this device... The column design allows for flexible adjustment of the ventilation efficiency of the compartment device. By rotating the threaded cylinder, the grate can be adjusted to single or double layers according to processing requirements. This single or double layer adjustment function provides more options for different grinding stages. At the same time, the threaded column and threaded cylinder allow for the replacement of grate plates with different sizes of grate holes. Different materials may require different ventilation volumes and flow rates during the grinding process. By replacing grate plates with different sizes of grate holes, the flow rate of the material in the mill can be adjusted, thereby meeting the specific requirements of different materials for the grinding environment.

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] like Figure 1 As shown in Figure 5, the specific solution of the embodiment is as follows: A tube mill compartment device with adjustable ventilation efficiency includes a plate frame 1 installed on the tube mill. The plate frame 1 is provided with an inner ring sleeve 102. The plate frame 1 is detached from the inner ring sleeve 102 by fixing bolts, or the inner ring sleeve 102 is connected to the plate frame 1 by stiffening plates 101. There are several stiffening plates 101, and these stiffening plates 101 are arranged in a circular array with the center point of the inner ring sleeve 102 as the base point. The mounting frame 2 is connected to two of the stiffening plates 101. Between 1, the plate frame 1 serves as the basic framework of the entire compartment device. The plate frame 1 provides a stable support structure to ensure that other components can be correctly installed and function. Between the plate frame 1 and the inner ring sleeve 102, there are several mounting frames 2. Through the mounting frames 2, components such as the partition 3 and the crossbeam 6 can be fixed together to form an independent compartment. The design of the mounting frames 2 allows the layout of the compartment to be flexibly adjusted according to actual needs. The several mounting frames 2 are distributed in a ring array with the center point of the plate frame 1 as the base point.

[0032] Each of the mounting frames 2 is provided with a pair of mounting seats 201, and each pair of mounting seats 201 is provided with mounting holes 202. The mounting holes 202 are connected to the plate frame 1 by fixing bolts. The mounting holes 202 on the mounting seats 201 are used to connect the mounting frame 2 and the plate frame 1 by fixing bolts. This connection method is not only firm and reliable, but also easy to disassemble and replace. As a key component connecting the mounting frame 2 and the plate frame 1, the fixing bolts ensure the stability and integrity of the entire compartment device.

[0033] Each of the mounting frames 2 is provided with a partition 3. The partition 3 is set so that the material can be ground in different chambers. This design helps to achieve a reasonable match between the material and the grinding media and improve the grinding efficiency. The partition 3 divides the mounting frame 2 into two chambers, namely the first placement chamber 4 and the second placement chamber 5. The design of the first placement chamber 4 and the second placement chamber 5 allows the first grate plate 801 and the second grate plate 802 to be disassembled and assembled separately. The number of chambers and the number of grate plate parts 8 can be varied according to the diameter of the frame 1.

[0034] The inner sides of the first placement chamber 4 and the second placement chamber 5 are respectively provided with several crossbeams 6. The crossbeams 6 not only enhance the structural strength of the chamber body, but also provide support for the installation of the threaded columns 7. The crossbeams 6 and the partition plate 3 are all arc-shaped. The arc-shaped crossbeams 6 design can better adapt to the internal shape of the tube mill, reduce friction and wear. Furthermore, a pair of positioning columns 601 are installed on the crossbeams 6 and the partition plate 3 respectively. The pair of positioning columns 601 are symmetrically distributed. The positioning columns 601 are used to ensure the accuracy of the grate plate 8 and the pressure plate 9 during the installation process and prevent them from being displaced or deformed.

[0035] A threaded post 7 is installed on the middle crossbeam 6. A threaded cylinder 701 is connected to the end of the threaded post 7 away from the middle crossbeam 6. The outer side of the threaded cylinder 701 is provided with anti-slip texture 702. The threaded post 7 is a key component connecting the grate plate 8 and the crossbeam 6. By rotating the threaded cylinder 701, the grate plate 8 can be easily disassembled and assembled. The anti-slip texture 702 design on the outer side of the threaded cylinder 701 makes the rotation operation simpler and more reliable. At the same time, the cooperation between the threaded cylinder 701 and the threaded post 7 also ensures the stability and firmness of the grate plate 8.

[0036] The inner side of the mounting frame 2 is provided with a grate plate 8 that connects with the threaded post 7. The grate plate 8 includes a first grate plate 801 and a second grate plate 802. The first grate plate 801 and the second grate plate 802 are located in the first placement chamber 4 and the second placement chamber 5, respectively. The first grate plate 801 and the second grate plate 802 are provided with a plurality of grate holes, which are equidistantly distributed. The grate holes on the grate plate are used to adjust the ventilation volume, thereby controlling the flow rate of the material in the mill. By replacing the grate plate 8 with grate holes of different sizes, the needs of different materials and grinding stages can be adapted.

[0037] The threaded post 7 is provided with a pressure plate 9 for limiting and fixing the grate plate 8. The pressure plate 9 is used to limit and fix the grate plate 8 to ensure that the grate plate 8 will not be displaced or fall off during rotation and adjustment. The connecting hole 901 and the positioning hole 902 on the pressure plate 9 are connected to the threaded post 7 and the positioning post 601 to achieve reliable connection and fixation. The pressure plate 9 and the first grate plate 801 and the second grate plate 802 are respectively provided with connecting holes 901 and positioning holes 902, and the position of the connecting hole 901 is connected to the threaded post 7.

[0038] The inner ring sleeve 102 is provided with a ventilation screen plate 10. The ventilation screen plate 10 has a double-layer structure and is connected to the inner ring sleeve 102. A pair of fixed seats 1001 are provided on the ventilation screen plate 10, and a handle 1002 is installed between the pair of fixed seats 1001. The ventilation screen plate 10 is located in the middle of the plate frame 1. Its double-layer structure design enhances ventilation efficiency. The design of the fixed seats 1001 and handle 1002 on the ventilation screen plate 10 allows the operator to easily adjust the position and angle of the ventilation screen plate 10 to adapt to different grinding needs.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
