Description

Technical Field

[0001] The utility model relates to the technical field of cement plant equipment, in particular to an energy-saving control device for a high-temperature fan in a cement plant. Background Art

[0002] The high-temperature fan of a cement plant is the power source of the firing system. It is mainly responsible for providing power for gas flow and maintaining the negative pressure environment of the system. It plays a vital role in cement production. It not only ensures the effective flow of gas during the production process, but also has an important impact on environmental protection and system stability. In actual use, high-temperature fans are equipped with control devices for use. However, when the existing high-temperature fan energy-saving control device is in use, the control device lacks a fixing mechanism for the control line, which makes the control line easy to loosen.

[0003] In order to address the above problems, a Chinese patent with the existing announcement number CN220151584U proposes an energy-saving control device for a high-temperature fan in a cement plant. The device presses down the lifting frame so that the lifting frame drives the two clamps to move relatively close to each other, and clamps and fixes the control line through the arc-shaped clamp. Then, the same positioning block is inserted into the positioning groove to fix the lifting frame, thereby fixing the control line.

[0004] However, although the above-mentioned energy-saving control device for high-temperature fans in cement plants can drive the two clamps to move relatively close to each other through a lifting frame to clamp and fix the control line, the positioning slot of the energy-saving control device for high-temperature fans in cement plants is fixed, so that the clamps can only clamp and fix control lines of specified sizes, thereby causing the problem of reduced application scope of the device. Therefore, the utility model provides an energy-saving control device for high-temperature fans in cement plants to meet the needs. Utility Model Content

[0005] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes an energy-saving control device for high-temperature fans in cement plants.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A cement plant high temperature fan energy-saving control device, comprising:

[0009] The fan body, the waste heat air pipe, the vector inverter, the controller and the control line, the controller has two clamping plates that rotate relative to each other, the clamping plates are provided with clamping grooves relative to each other, the controller has support plates relatively to each other along the clamping plates, a half gear is provided at the bottom of the clamping plate, the half gear is rotatably connected to the support plate through a rotating shaft 1, a torsion spring is sleeved on the rotating shaft, a guide plate that extends outward and is an arc-shaped structure is integrally formed on the top of the clamping plate, and the guide plates on the two clamping plates are arranged relative to each other.

[0010] Preferably, the distance between adjacent guide plates is smaller than the distance between two clamping grooves, and a rubber pad is fixedly connected in the clamping groove.

[0011] Preferably, the clamping plate is fixedly connected to a curved rod on one side away from the clamping groove, a fixed block is fixedly connected inside the controller, a spherical block is fixedly connected to one end of the curved rod away from the clamping plate, the spherical block is slidably connected to the fixed block, a sliding groove is provided in the fixed block for the spherical block to slide, and a spring fixedly connected to the spherical block is provided in the sliding groove.

[0012] Preferably, the arc-shaped rod and the slide groove are both matching arc-shaped structures.

[0013] Preferably, the width of the spherical block is greater than the width of the arc-shaped rod.

[0014] Preferably, it also includes a limit block, which is a semi-cylindrical structure and is rotatably arranged between the clamping plate and the guide plate through a second rotating shaft. The clamping plate is provided with a rotating groove for the limit block to rotate, and a limit groove that is connected to the rotating groove and can limit the limit block.

[0015] Preferably, the limiting block is located at the bottom of one side of the rotating groove and is fixedly connected with a counterweight block.

[0029] like Figures 1 to 7As shown, an embodiment of the utility model provides an energy-saving control device for a high-temperature fan in a cement plant, comprising a fan body 1, a waste heat air pipe 2, a vector inverter 3, a controller 5 and a control line 4, two clamping plates 7 are relatively rotated in the controller 5, and clamping grooves 17 are relatively provided on the clamping plates 7, and support plates 13 are relatively provided along the clamping plates 7 of the controller 5, and a half gear 12 is provided at the bottom of the clamping plate 7, and the half gear 12 is rotatably connected to the support plate 13 through a rotating shaft 15, and a torsion spring 9 is sleeved on the rotating shaft, and a guide plate 14 extending outward and having an arc-shaped structure is integrally formed on the top of the clamping plate 7, and the guide plates 14 on the two clamping plates 7 are relatively arranged.

[0030] Specifically, by embedding the control line 4 along the guide plate 14, the control line 4 squeezes the guide plate 14, so that the guide plate 14 drives the clamping plate 7 to rotate, and the clamping plate 7 drives the two half gears 12 to rotate relative to each other and squeeze the torsion spring 9, so that the control line 4 enters the clamping groove 17, and the elastic force of the torsion spring 9 enables the two clamping plates 7 to clamp the control line 4, thereby preventing the control line 4 from loosening. At the same time, it is also possible to clamp control lines 4 of different diameters, thereby improving the use range of the device. Similarly, when the control line 4 needs to be taken out, it is only necessary to use external force to rotate one of the clamping plates 7 so that the two clamping plates 7 move relative to each other, thereby facilitating the removal of the control line 4, thereby solving the problem that the positioning groove of the existing energy-saving control device of the high-temperature fan in the cement plant is fixed, so that the clamping plate can only clamp and fix the control line 4 of a specified size, thereby reducing the application range of the device.

[0031] It should be noted that the controller 5 is provided with a threading hole 8 for the control line 4 to enter, and an opening capable of supporting the control line 4 to be installed in the holding plate. At the same time, the two ends of the torsion spring 9 are fixedly connected to the half gear 12 and the support plate 13 respectively; further, the waste heat air pipe 2 is connected to the fan body 1, the pressure transmitter is installed in the waste heat air pipe 21 at the end of the kiln, the pressure transmitter circuit is connected to the controller 5, the controller 5 is connected to the vector frequency converter 3 through the control line 4, and the vector frequency converter 3 is connected to the drive motor of the fan body 1. This part can refer to the patent documents with publication numbers CN203500070 and CN220151584U, which are prior art and can be directly quoted.

[0032] like Figure 4 and Figure 5 As shown, in this embodiment, the distance between adjacent guide plates 14 is smaller than the distance between two clamping grooves 17 , and a rubber pad 16 is fixedly connected in the clamping groove 17 .

[0033] like Figure 2 and Figure 7As shown, in the present embodiment, the side of the clamping plate 7 away from the clamping groove 17 is fixedly connected with an arc rod 10, and a fixed block 11 is fixedly connected in the controller 5. The end of the arc rod 10 away from the clamping plate 7 is fixedly connected with a spherical block 23, and the spherical block 23 is slidably connected with the fixed block 11. A sliding groove 24 is provided in the fixed block 11 for the spherical block 23 to slide, and a spring 6 fixedly connected to the spherical block 23 is provided in the sliding groove 24. The arc rod 10 and the sliding groove 24 are both matching arc structures, and the width of the spherical block 23 is greater than the width of the arc rod 10. Specifically, when the clamping plate 7 rotates relatively away from each other, the clamping plate 7 drives the arc rod 10 to push the spherical block 23 to slide along the sliding groove 24, so that the spherical block 23 squeezes the spring 6. The clamping force at the top of the two clamping plates 7 can be increased by the spring 6, so as to avoid the control line 4 from escaping along the clamping groove 17, thereby improving the stability of the clamping of the control line 4.

[0034] like Figure 5 and Figure 6 As shown, in this embodiment, a limit block 18 is also included, which is a semi-cylindrical structure and is rotatably arranged between the clamping plate 7 and the guide plate 14 through a second rotating shaft 19. A rotation groove 20 for the limit block 18 to rotate is provided in the clamping plate 7, and a limit groove 21 is communicated with the rotation groove 20 and can limit the limit block 18. The limit block 18 is located at one side of the rotation groove 20 and is fixedly connected to a counterweight block 22 at the bottom. Specifically, the arc end face of the limit block 18 is located at the top, and the horizontal end face is located at the bottom. When the control line 4 enters the guide groove along the guide plate 14, the control line 4 will push the limit block 18 to rotate until the limit block 18 is limited in the limit groove 21. When the control line 4 enters the clamping groove, the limit block 18 is reset under the influence of the counterweight block 22. At this time, the horizontal end face of the limit block 18 is located at the bottom, and is matched with the rotating groove 20 to limit the control line 4 in the clamping groove 17, so as to prevent the control line 4 from moving along the clamping groove 17 toward the guide plate 14, thereby improving the limiting ability of the control line 4.

[0035] Working principle:

[0036] By embedding the control line 4 along the guide plate 14, the control line 4 squeezes the guide plate 14, so that the guide plate 14 drives the clamping plate 7 to rotate, and the clamping plate 7 drives the two half gears 12 to rotate relatively and squeeze the torsion spring 9, so that the control line 4 enters the clamping groove 17, and the elastic force of the torsion spring 9 makes the two clamping plates 7 clamp the control line 4, thereby preventing the control line 4 from loosening. At the same time, when the clamping plates 7 rotate relatively away from each other, the clamping plates 7 drive the arc rod 10 to push the spherical block 23 to slide along the slide groove 24, so that the spherical block 23 squeezes the spring 6, and the clamping force of the top of the two clamping plates 7 can be increased by the spring 6. Similarly, when the control line 4 needs to be taken out, only one of the clamping plates 7 needs to be rotated by external force, so that the two clamping plates 7 move relative to each other, thereby facilitating the removal of the control line 4, and solving the problem that the positioning groove position of the existing energy-saving control device of the high-temperature fan in the cement plant is fixed, so that the clamping plate can only clamp and fix the control line 4 of a specified size, thereby reducing the application range of the device.
