Description
Technical Field
[0001] The utility model relates to the technical field of gas throttling devices, and particularly relates to a pneumatic ash conveying throttling device. Background Art
[0002] With the gradual improvement of the national environmental protection intensity and standards, problems such as dust environmental pollution are common in industries such as metallurgy, cement, and building materials. To further control dust pollution problems, various conveying and transportation methods have emerged. The dust collector collects fine dust materials, and the collected dust is transported to a designated location through a transfer method. During the collection and transportation of dust, a pneumatic ash conveying device or a pneumatic ash conveying system is required for ash conveying. Among them, a throttle or a throttling device needs to be used in the pneumatic ash conveying system. The throttling device can reduce the flow rate of compressed air, reduce pipeline wear, and extend the service life. However, the existing ash conveying system mainly uses large-diameter and large-flow compressed air pipelines to achieve gas transportation. The existing throttling device cannot be quickly adapted to large-diameter and large-flow air pipelines for use, and the existing throttling device cannot adjust the flow rate of the conveyed gas, reducing the overall practicability of the throttling device. Content of the Utility Model
[0003] In order to overcome the defects existing in the prior art, the utility model provides a pneumatic ash conveying throttling device.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a pneumatic ash conveying throttling device, including a first throttle plate and a second throttle plate. A connecting flange is arranged on one side of the first throttle plate. A regulating plate is movably arranged on the side of the connecting flange away from the first throttle plate. A second throttle plate is arranged on the side of the regulating plate away from the connecting flange. First through holes are formed in the first throttle plate and the second throttle plate. A second through hole is formed in the connecting flange. A third through hole is formed in the regulating plate. The first through hole, the second through hole, and the third through hole are located on the same center line and are interconnected. The diameter of the first through hole is larger than that of the second through hole and the third through hole.
[0005] In a further description of this solution, first screw holes are formed in the upper and lower parts of the side surface of the first throttle plate away from the connecting flange, and second screw holes are formed in the left and right parts of the side surface of the first throttle plate away from the connecting flange. The first screw holes and the second screw holes extend to one side and penetrate through the connecting flange, the regulating plate, and the second throttle plate. A first fastening screw and a second fastening screw are respectively arranged in the first screw holes and the second screw holes.
[0006] Specifically, an annular sliding groove is formed on one side of the connecting flange close to the adjusting plate. A convex column is arranged on one side of the adjusting plate close to the connecting flange. The convex column is movably arranged in the annular sliding groove. Strip-shaped holes are formed at the upper and lower ends of the adjusting plate.
[0007] More specifically, the strip-shaped holes are in sliding fit with the first fastening screws, so that the adjusting plate can swing by cooperating with the first fastening screws through the strip-shaped holes.
[0008] In a further description of this solution, a first sealing gasket is arranged between the first throttle plate and the connecting flange, and a second sealing gasket is arranged between the second throttle plate and the adjusting plate.
[0009] Specifically, fourth through holes are formed inside the first sealing gasket and the second sealing gasket. The fourth through holes are located on the same center line as the first through hole, the second through hole, and the third through hole and are interconnected with each other. The diameter of the fourth through hole is the same as that of the first through hole.
[0010] The beneficial effects of the present utility model are as follows:
[0011] 1. When this throttle device is in use, it can be first connected to the air pipeline, so that the first through holes inside the first throttle plate and the second throttle plate are respectively communicated with the air pipeline, so that the gas in the subsequent air pipeline can first enter the second through hole inside the connecting flange from the first through hole of the first throttle plate, and then enter the third through hole inside the adjusting plate, and finally be discharged to the outside through the first through hole inside the second throttle plate. The diameter of the first through hole is larger than that of the second through hole and the third through hole. In this way, when the gas enters the second through hole and the third through hole from the first through hole, the gas flow rate can be reduced. By reducing the gas flow rate, the wear of the inner wall of the pipeline caused by excessive gas flow can be avoided, and thus it can quickly adapt to large-diameter and large-flow air pipelines for use.
[0012] 2. And an adjusting plate is arranged in this throttle device. By adjusting the position of the adjusting plate, the third through hole can be moved, so as to realize the intersection of the third through hole and the second through hole, and thus the flow rate of the transported gas in the throttle device can be adjusted through adjustment, so as to improve the overall practicability of the throttle device.

Specific embodiments
[0018] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0019] As shown in Figure 1 , 2 , 3 and 4, a pneumatic ash conveying throttling device provided by the present utility model includes a first throttle plate 1 and a second throttle plate 2. A connecting flange 3 is arranged on one side of the first throttle plate 1. An adjusting plate 4 is movably arranged on the side of the connecting flange 3 away from the first throttle plate 1. A second throttle plate 2 is arranged on the side of the adjusting plate 4 away from the connecting flange 3. A first through hole 5 is opened inside the first throttle plate 1 and the second throttle plate 2. A second through hole 6 is opened inside the connecting flange 3. A third through hole 7 is opened inside the adjusting plate 4. The first through hole 5, the second through hole 6 and the third through hole 7 are located on the same center line and communicate with each other. The diameter of the first through hole 5 is larger than that of the second through hole 6 and the third through hole 7.
[0020] When the throttling device needs to be used: it can be installed in the air pipeline of the pneumatic ash conveying equipment, so that the first through holes 5 inside the first throttle plate 1 and the second throttle plate 2 are respectively communicated with the air pipeline. In this way, the gas in the air pipeline can enter the throttling device through the first throttle plate 1, so that the gas can first enter the second through hole 6 inside the connecting flange 3 from the first through hole 5 of the first throttle plate 1, then enter the third through hole 7 inside the adjusting plate 4, and finally be discharged to the outside through the first through hole 5 inside the second throttle plate 2. The diameter of the first through hole 5 is larger than that of the second through hole 6 and the third through hole 7. In this way, when the gas enters from the first through hole 5 into the second through hole 6 and the third through hole 7, the gas can enter from the large-diameter through hole to the small-diameter through hole, so that the gas discharge flow can be reduced. By reducing the gas flow, the wear of the inner wall of the pipeline caused by excessive gas flow can be avoided, so that it can quickly adapt to large-diameter and large-flow air pipelines for use, and it can also prevent the air pipeline from being damaged during operation, avoiding affecting production and polluting the environment.
[0021] At the same time, an adjusting plate 4 is provided. The position of the adjusting plate 4 is adjusted by manual operation. By controlling the position of the adjusting plate 4, the position of the third through hole 7 can be changed, so that the second through hole 6 and the third through hole 7 can be prevented from being on the same center line, so as to realize the intersection of the third through hole 7 and the second through hole 6. In this way, the flow rate of the conveying gas in the throttling device can be adjusted by adjustment, so as to improve the overall practicality of the throttling device.
[0022] As shown in Figure 1 , 2 , 3 and 4, on the upper and lower parts of the side surface of the first throttle plate 1 away from the connecting flange 3, first screw holes 8 are opened, and on the left and right parts of the side surface of the first throttle plate 1 away from the connecting flange 3, second screw holes 9 are opened. The first screw holes 8 and the second screw holes 9 extend to one side and penetrate through the connecting flange 3, the adjusting plate 4 and the second throttle plate 2. And first fastening screws 10 and second fastening screws 11 are respectively arranged in the first screw holes 8 and the second screw holes 9, so that the first throttle plate 1, the second throttle plate 2, the connecting flange 3 and the adjusting plate 4 can be fastened by the first fastening screws 10 and the second fastening screws 11.
[0023] As shown in Figure 1 , 2 , 3 and 4, on the side of the connecting flange 3 close to the adjusting plate 4, an annular sliding groove 12 is opened. On the side of the adjusting plate 4 close to the connecting flange 3, a convex column 13 is arranged. The convex column 13 is movably arranged in the annular sliding groove 12. Strip-shaped holes 14 are opened at the upper and lower ends of the adjusting plate 4. Subsequently, the strip-shaped holes 14 are slidably matched with the first fastening screws 10, so that the adjusting plate 4 can swing by cooperating with the first fastening screws 10 through the strip-shaped holes 14.
[0024] When it is necessary to adjust the position of the third through hole 7 inside the adjusting plate 4: the adjusting plate 4 can be rotated by manual swinging. The left and right swinging of the adjusting plate 4 is achieved through the mutual cooperation of the strip-shaped hole 14 and the first fastening screw 10. When the adjusting plate 4 swings left and right, the mutual cooperation of the convex column 13 and the annular sliding groove 12 can achieve the guiding of the adjusting plate 4 during swinging, avoiding the situation of deviation when the adjusting plate 4 swings left and right. In this way, when the adjusting plate 4 swings left and right, the position of the third through hole 7 can be changed, so that the third through hole 7 and the second through hole 6 can be staggered, thereby adjusting the opening diameter of the third through hole 7 and realizing the adjustment of the gas flow rate.
[0025] As shown in Figure 1 , 2 , 3, and 4, a first sealing gasket 15 is provided between the first throttle plate 1 and the connecting flange 3, and a second sealing gasket 16 is provided between the second throttle plate 2 and the adjusting plate 4. By providing the first sealing gasket 15 and the second sealing gasket 16, the overall sealing performance of the throttling device can be improved.
[0026] Subsequently, a fourth through hole 17 is opened inside the first sealing gasket 15 and the second sealing gasket 16. The fourth through hole 17 is located on the same center line as the first through hole 5, the second through hole 6, and the third through hole 7 and is interconnected. The diameter of the fourth through hole 17 is the same as that of the first through hole 5. By providing the fourth through hole 17, the blocking of the gas by the sealing gasket can be avoided, ensuring the normal flow of the gas.
[0027] The above has described in detail the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principles and spirit of the present invention, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present invention.
