Abstract
Description
Technical Field
[0001] This invention relates to a double-layer ash discharge valve, specifically a double-layer ash discharge valve plate cleaning device. Background Technology
[0002] Currently, sintering machines used in the metallurgical industry are equipped with dust collectors at the machine head. These dust collectors are typically divided into electrostatic precipitators or bag filters. The dust collected by the dust collector falls onto the conveying mechanism below through pipes. To effectively control ash discharge, a double-layer ash discharge valve is installed between the pipes and the conveying mechanism. Because the ash discharge valve has good sealing properties, it isolates materials and air, and is used to open or cut off the pipes for ash discharge. Therefore, in addition to the material dust falling and being discharged through the valve plate, the material dust contains micron-sized particles smaller than 1mm, which are easily airborne and have strong adhesion, adhering to the valve plate surface and unable to detach on their own. At ambient temperature, these particles absorb moisture, causing adhesion and resulting in incomplete valve sealing and air leakage. This vicious cycle leads to increasing ash accumulation on the valve plate, and in severe cases, even damage to the valve plate. Manual cleaning of the ash discharge valve plate is required to restore normal sealing, which is time-consuming and labor-intensive due to the harsh working environment. Given this situation, it is imperative to develop a cleaning device that can remove accumulated dust from adhesive valve plates without the need for operators, which has become an urgent problem to be solved. Summary of the Invention
[0003] In view of the above situation, the purpose of this utility model is to provide a valve plate cleaning device for a double-layer ash discharge valve. By using the valve plate cleaning device to clean the ash accumulated on the valve plate, the cleaning work of the operator is avoided, and the valve plate of the double-layer ash discharge valve can be guaranteed to have good sealing performance.
[0004] The technical solution of this utility model is: a double-layer ash discharge valve plate cleaning device, including a double-layer ash discharge valve body and upper and lower valve plates inside; wherein, upper and lower valve plate cleaning mechanisms are respectively provided on one side of the double-layer ash discharge valve body at the adjacent positions of the upper and lower valve plates; the upper and lower valve plate cleaning mechanisms can clean the material dust adhering to the surface of the alternately opened upper and lower valve plates.
[0005] In this invention, the upper valve plate cleaning mechanism includes an upper cleaning reduction motor, an upper cleaning arm is fixed to one end of the output shaft of the upper cleaning reduction motor, and an upper cleaning body is mounted on the upper cleaning arm. The upper cleaning body can swing and clean within a 90° range.
[0006] In this invention, the lower valve plate cleaning mechanism includes a lower cleaning reduction motor, a lower cleaning arm is fixed to one end of the output shaft of the lower cleaning reduction motor, and a lower cleaning body is mounted on the lower cleaning arm. The lower cleaning body can swing and clean within a 90° range.
[0007] Furthermore, the upper and lower cleaning bodies are either wire brushes or elastic metal scraper blades. Therefore, through the upper and lower wire brushes or elastic metal scraper blades in the upper and lower valve plate cleaning mechanism, there is a certain amount of clamping force between them and the upper and lower valve plates. Utilizing the flexibility of the upper and lower wire brushes, after cleaning the valve plates, the wires return to their vertical position, shaking off the dust. Similarly, the scraping is performed using the reciprocating deformation of the elastic scraper blades.
[0008] The beneficial effects of this utility model are as follows: The upper and lower valve plate cleaning mechanisms installed on the upper and lower valve plates can effectively clean the material dust adhering to them, thus solving the problem of air leakage caused by poor sealing due to the material dust adhering to the upper and lower valve plates. Furthermore, the self-cleaning function of the upper and lower valve plate cleaning mechanisms eliminates the need for manual cleaning and reduces labor intensity. Attached Figure Description
[0009] Figure 1 is a view of the present invention;
[0010] Figure 2 This is a side view of Figure 1;
[0011] Figure 3 This is the rear side view of Figure 1. Detailed Implementation
[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0013] See Figure 1 to Figure 3 The double-layer ash discharge valve plate cleaning device shown includes an upper valve plate 4 and a lower valve plate 10 respectively located at the upper and lower ash discharge ports on the inner side of the double-layer ash discharge valve body 1. The upper valve plate 4 and the lower valve plate 10 control the alternating discharge of material from the upper and lower ash discharge ports. The upper valve plate 4 and the lower valve plate 10 are respectively mounted on the upper rotating shaft 3 and the lower rotating shaft 7, and are connected to their respective upper reduction motor 2 and lower reduction motor 9 through the lead-out ends of the upper rotating shaft 3 and the lower rotating shaft 7. The upper reduction motor 2 and the lower reduction motor 9 alternately control the opening or closing of the upper valve plate 4 and the lower valve plate 10. In this embodiment, an upper valve plate cleaning mechanism A and a lower valve plate cleaning mechanism B are respectively provided on the inner side of the cavity of the double-layer ash discharge valve body 1 at the adjacent positions of the upper valve plate 4 and the lower valve plate 10. The upper valve plate cleaning mechanism A and the lower valve plate cleaning mechanism B can clean the material dust adhering to the surface of the alternately opened upper valve plate 4 and the lower valve plate 10.
[0014] In the above description, the upper valve plate cleaning mechanism A includes an upper cleaning reduction motor 12, a cleaning arm 5 fixed to one end of the output shaft of the upper cleaning reduction motor 12, and an upper cleaning body 6 mounted on the upper cleaning arm 5. In this embodiment, the upper cleaning body 6 is a wire brush, which can swing and clean the surface of the upper valve plate 4 within a 90° range.
[0015] As described above, the lower valve plate cleaning mechanism B includes a lower cleaning reduction motor 13, a lower cleaning arm 8 fixed to one end of the output shaft of the lower cleaning reduction motor 13, and a lower cleaning body 11 mounted thereon. In this embodiment, the lower cleaning body 11 is a wire brush, which can swing and clean the surface of the lower valve plate 10 within a 90° range.
[0016] In the above-mentioned components, besides the upper cleaning body 6 and the lower cleaning body 11 which use wire brushes, elastomeric metal scraper blades can also be used. The scraping is achieved through the reciprocating deformation of the elastomeric scraper blades. Its function and effect are the same as those of a wire brush.
[0017] In the above, there is a certain amount of clamping force between the upper cleaning body 6, the lower cleaning body 11 and the surfaces of the upper valve plate 4 and the lower valve plate 10. With the help of the wire brush's flexibility, after cleaning the valve plate, the wire brush returns to its vertical position and can shake off the material dust.
[0018] The upper cleaning arm 5 and the lower cleaning arm 8 are positioned parallel to the upper valve plate 4 and the lower valve plate 10, respectively; while the upper cleaning body 6 and the lower cleaning body 11 are perpendicular to the surfaces of the upper valve plate 4 and the lower valve plate 10 when they are in the open state. This ensures that the upper cleaning body 6 and the lower cleaning body 11 perform parallel cleaning with the surfaces of the upper valve plate 4 and the lower valve plate 10.
[0019] The double-layer ash discharge valve closing valve plate feeding and valve plate cleaning process:
[0020] 1. When loading materials, both the upper valve plate 4 and the lower valve plate 10 inside the double-layer ash discharge valve body 1 are in the closed state;
[0021] 2. Material is fed into the cavity closed by the upper valve plate 4 through the upper feeding port of the double-layer ash discharge valve body 1, and the material falls onto the upper valve plate 4;
[0022] 3. Stop feeding material from above, start the upper reduction motor 2 to open the upper valve plate 4, and the material falls onto the lower valve plate 10. During the material discharge time when the upper valve plate 4 is open, start the upper cleaning reduction motor 12 to control the upper cleaning body 6 to clean the material adhering to the surface of the upper valve plate 4. After cleaning is completed, the upper cleaning body 6 resets, the upper cleaning reduction motor 12 stops working, the upper valve plate 4 closes, and material is fed into the closed cavity of the upper valve plate 4.
[0023] 4. When discharging material into the double-layer ash discharge valve body 1, the lower valve plate 10 opens, and the material is discharged through the discharge port at the bottom of the ash discharge valve body 1. During the material discharge period while the lower valve plate 10 is open, the lower cleaning reduction motor 13 is started to control the lower cleaning body 11 to clean the material adhering to the surface of the lower valve plate 10. After cleaning is completed, the lower cleaning body 11 resets, the lower cleaning reduction motor 13 stops working, and the lower valve plate 10 closes. This process is repeated. In this way, the problem of poor sealing or even air leakage caused by material adhering to the upper valve plate 4 and the lower valve plate 10 is effectively solved by the upper valve plate cleaning mechanism A and the lower valve plate cleaning mechanism B.
