Description

Technical Field

[0001] This utility model belongs to the technical field of coal conveying systems, and specifically refers to a three-way device for coal conveying systems. Background Technology

[0002] In modern industry, coal conveying systems are crucial for energy conversion and transmission, and their efficiency and stability are paramount. Electric three-way valves, as an important component of these systems, are responsible for switching and distributing coal flows. However, traditional electric three-way valves often face the problem of excessive starting torque. This is because when coal flows through the valve, factors such as the coal's own weight, viscosity, and the frictional resistance of the pipeline require the electric actuator to overcome these resistances to operate normally. Furthermore, friction between mechanical components and the inertia of the electric actuator itself further increase the starting torque required.

[0003] Excessive starting torque not only increases equipment energy consumption and operating costs, but also may subject the equipment to impact loads due to the peak torque generated during startup, thereby accelerating the wear of vulnerable parts such as bearings and gears and shortening the equipment's service life. Furthermore, prolonged high-load startup can affect the accuracy and stability of the electric actuator, thus impacting the stability and reliability of the entire coal conveying system. In extreme cases, excessive starting torque may even prevent the electric actuator from starting properly, thus affecting the normal operation of the entire production line. Utility Model Content

[0004] The main purpose of this utility model is to provide a three-way device for coal conveying systems, which solves the problems existing in the prior art, effectively reduces the starting torque of the electric push rod, and realizes the optimization and upgrading of the three-way device. It can not only improve equipment performance, but also has significant advantages such as energy saving, emission reduction, cost reduction and efficiency improvement.

[0006] A three-way device for a coal conveying system includes a three-way body, a baffle, a drive device, and springs; the three-way body has one inlet and two outlets; the baffle is oscillatingly fitted within the three-way body to open and close the two outlets; a swing arm is provided at the end of the rotating shaft of the baffle; the drive device is kinetically connected to the swing arm to drive the swing arm to swing in conjunction with the baffle to achieve oscillation; the springs are connected between both sides of the swing arm and both sides of the three-way body; in the initial state, the baffle is in the middle state between the two outlets, and both springs are preset to be in a stretched state.

[0007] The inlet is located on the upper surface of the tee body, and the two outlets are located on the lower surface of the tee body, with the two outlets symmetrically arranged on the left and right sides below the inlet.

[0028] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0029] refer to Figure 1-7 As shown, this utility model discloses a three-way device for a coal conveying system, including a three-way body 1, a baffle 2, a driving device 3, and a spring 4;

[0030] The three-way body 1 is provided with one inlet 11 and two outlets 12;

[0031] The baffle 2 is oscillatingly fitted inside the tee body 1 to open and close the two outlets 12; the end of the pivot 21 of the baffle 2 is provided with a swing arm 22; here, since the baffle 2 is located inside the tee body 1, the baffle 2 is shown in perspective with dashed lines in the attached figure.

[0032] The drive device 3 is connected to the swing arm 22 in a transmission manner, and is used to drive the swing arm 22 to swing in conjunction with the baffle 2 to achieve the swing.

[0033] Springs 4 are connected between both sides of the swing arm 22 and both sides of the three-way body 1;

[0034] In the initial state, the baffle 2 is in the middle of the two outlets 12, and both springs 4 are preset to be in the stretched state.

[0035] Through the above-described scheme, the technical advantage of this patent application lies in utilizing the unique properties of the spring 4, namely, the spring 4 can store energy when stretched or compressed and quickly return to its original shape when the external force is released. This characteristic makes the spring 4 an ideal energy storage and release device. By combining the spring 4, which is preset to a stretched state, with the drive device 3, this utility model can absorb part of the starting torque in the initial stage of the drive device 3, thereby effectively reducing the starting torque of the drive device 3. This not only reduces costs and is easy to implement, but also has significant energy-saving effects and improved reliability. This utility model can also improve the response speed and stability of the drive device 3, and its application in coal conveying systems has significant implications for energy efficiency and environmental protection.

[0036] Reducing the starting torque of the electric three-way valve in the coal conveying system is of significant necessity and practical importance.

[0037] (1) Energy conservation and emission reduction

[0038] Reducing the starting torque can effectively reduce unnecessary energy consumption of equipment during the start-up phase, thereby reducing the energy consumption of the entire coal conveying system, which is of great significance for achieving green and low-carbon production.

[0039] (2) Reduce wear and extend equipment life

[0040] Reducing the starting torque can lessen the impact load during equipment startup, effectively reduce the wear rate of equipment components, and extend the service life of the equipment. This has a significant effect on reducing operating costs and improving the economic efficiency of equipment operation.

[0041] (3) Improve system stability and reliability

[0042] Reducing the starting torque can not only improve the starting performance of the equipment, but also enhance the stability and reliability of the entire coal conveying system. This is of great significance for ensuring production efficiency, reducing downtime due to malfunctions, and improving product quality.

[0043] The following are specific embodiments of the present invention.

[0044] The aforementioned inlet 11 is located on the upper surface of the tee body 1, and the two outlets 12 are located on the lower surface of the tee body 1, with the two outlets 12 symmetrically arranged on the left and right sides below the inlet 11.

[0045] Both ends of the rotating shaft 21 of the aforementioned baffle 2 extend out of the three-way body 1, and both ends of the rotating shaft 21 are provided with swing arms 22, that is, the number of swing arms 22 is designed to be two; the driving device 3 and the two springs 4 are respectively connected to the two swing arms 22, so that the driving device 3 and the two springs 4 are located outside the three-way body 1 and do not interfere with the swing of the internal baffle 2, and the driving device 3 and the springs 4 will not interfere with each other.

[0046] Furthermore, a connecting plate 23 is provided at the end of the swing arm 22 connected to the spring 4, and a spring 4 is connected to each side of the connecting plate 23; a connecting rod 13 is provided on the surface of the three-way body 1 for connecting and fixing the end of the spring 4.

[0047] The aforementioned drive device 3 is an electric push rod, and the output rod 31 of the electric push rod is rotatably connected to the swing arm 22.

[0048] Furthermore, the aforementioned three-way device also includes a mounting bracket 5 for mounting an electric push rod, which is oscillatingly connected to the mounting bracket 5 to accommodate the angle changes caused by the extension and retraction of the electric push rod and its output rod 31 to drive the swing arm 22.

[0049] The side of the aforementioned three-way body 1 is provided with a transparent observation window 14 to facilitate observation of the status of the internal baffle 2.

[0050] See Figure 4-5 With the side of the three-way body 1 equipped with the electric push rod as the front, the baffle 2 is in the right-side position.

[0051] If the electric push rod is activated to move the baffle 2 from right to left (i.e., the electric push rod is pushed out), because the two springs 4 are in different states (one is stretched and the other is compressed), the resultant force of the overall tension of the springs 4 will be in the same direction as the push of the electric push rod, thus absorbing part of the starting torque first. As the electric push rod continues to move, the springs 4 gradually release the absorbed energy, assisting in switching the direction of the coal flow.

[0052] See Figure 6-7 At this time, baffle 2 is in the left position.

[0053] If the electric push rod is activated and the baffle 2 is to be moved from the left to the right (i.e., the electric push rod is retracted), because the two springs 4 are in different states (one is stretched and the other is compressed), the resultant force of the overall tension of the springs 4 is in the same direction as the retraction of the electric push rod, and will still absorb part of the starting torque.

[0054] Therefore, regardless of the state of the three-way device, the two springs 4 and their combined force can always play a role in assisting starting and reducing starting torque.

[0055] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
