Description

Technical Field

[0001] The utility model relates to the technical field of ash discharge equipment, in particular to a rubber ash discharge valve for a cyclone separator. Background Art

[0002] In the production process of fertilizers, the cyclone separator can effectively separate gas and solid impurities based on the centrifugal principle to ensure that the useful components in the raw materials are retained. The ash discharge valve at the bottom of the cyclone separator controls and discharges the separated dust or solid particles. The ash discharge valve is usually located at the bottom of the cyclone separator and is connected to the ash discharge pipe to ensure that the dust thrown to the cylinder wall by centrifugal action during the operation of the cyclone separator can be discharged smoothly and effectively.

[0003] Generally, a cyclone separator generally adopts an electric ash discharge valve with a sealing plate driven by a motor or a rubber ash discharge valve, such as the Chinese utility model patent disclosed by publication number CN206366462U: Cyclone separator rubber automatic ash discharge valve. This application sets a flexible baffle with a lower hardness at the bottom of the trapezoidal rubber skin, and uses a rubber pressure block to compress the overlapping part between the two in the length direction, thereby avoiding the situation where the lower part of the rubber skin rolls inwards and is sucked into the channel of the cyclone separator under the action of negative pressure, and at the same time reduces the size of the lower bottom opening. The flexible baffle has a tendency to roll inwards under the action of negative pressure, and fits more tightly. It is easy to seal the bottom, which reduces the air leakage during dust removal and reduces the load absorbed by the gravity settling chamber in the subsequent process. However, the rubber material of the trapezoidal rubber sheet and the rubber pressure block will age after a period of use. In addition, the bottom opening of the rubber duckbill valve will be subjected to repeated friction and wear during use, especially when the medium contains particulate matter. The wear is more serious, which eventually leads to a larger gap, thereby affecting the effect of the ash discharge valve. At the same time, the constant expansion pressure of the application may not be able to meet the needs of different working conditions, resulting in a decrease in the flexibility and stability of the system operation.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 5 As shown, the utility model provides a rubber ash discharge valve for a cyclone separator, comprising a rubber duckbill valve 1, a first connecting flange 2 and a second connecting flange 3. The first connecting flange 2 is inserted and installed on the outside of the rubber duckbill valve 1. A flat ash discharge port 9 is fixedly installed at the bottom of the rubber duckbill valve 1. Metal patches 6 are fixedly installed on both sides of the flat ash discharge port 9. Two mounting plates 4 are fixedly installed at the bottom of the second connecting flange 3. Adjustment shafts 5 are movably installed at the lower positions of the two mounting plates 4, and one side of the two adjustment shafts 5 is also movably connected to the corresponding metal patches 6.

[0023] like Figure 2-Figure 3As shown, a fixing flange 7 is fixedly installed on the top of the rubber duckbill valve 1, and the fixing flange 7 and the rubber duckbill valve 1 are integrally injection molded. A plurality of fixing bolts 16 are inserted and connected between the mounting plate 4 and the second connecting flange 3, the first connecting flange 2, and the fixing flange 7, that is, the first connecting flange 2 is fixedly installed on the bottom of the fixing flange 7 by the fixing bolts 16, and the mounting plate 4 is fixedly installed on the bottom of the second connecting flange 3 by the fixing bolts 16. The second connecting flange 3 is fixedly installed at a position below the first connecting flange 2 and is located outside the flat ash discharge port 9 by the fixing bolts 16. A filling ring 8 is inserted and installed between the first connecting flange 2 and the rubber duckbill valve 1. With the help of the setting of the filling ring 8, the gap between the first connecting flange 2 and the rubber duckbill valve 1 can be filled, thereby ensuring the installation stability of the upper part of the rubber duckbill valve 1, and preventing the gap with the first connecting flange 2 from causing repeated friction between the outer side of the rubber duckbill valve 1 and the first connecting flange 2, thereby reducing the service life;

[0024] like Figure 2 , Figure 4-Figure 5 As shown, a fixing seat 10 is fixedly installed on one side of the bottom of the mounting plate 4, and the mounting plate 4 and the fixing seat 10 are arranged at the bottom of the second connecting flange 3, which can provide basic conditions for the pulling and drawing of the adjusting shaft 5, a fixing ring 11 is fixedly installed on the outer side of the adjusting shaft 5, a knob 12 is fixedly installed on one end of the adjusting shaft 5, and a screw groove 13 is opened at the other end of the adjusting shaft 5, and the adjusting shaft 5 is inserted and installed in the corresponding fixing seat 10, and the adjusting shaft 5 between the fixing seat 10 and the fixing ring 11 is provided with a compression spring 15, and a screw rod 14 is fixedly installed at the center position of one side of the metal patch 6, and the screw rod 14 is threadedly connected with the screw groove 13 at one end of the corresponding adjusting shaft 5. With the help of the setting of the fixing seat 10, the metal patch 6 and the screw rod 14, the expansion pressure of the flat ash discharge port 9 can be adjusted, so as to be adjusted according to production needs. At the same time, the adjusting shaft 5 can also cooperate with the mounting plate 4 and the metal patch 6 to manually expand the flat ash discharge port 9, so that the residual dust in the cyclone separator 17 can be removed after the production is completed.

[0025] It should be noted that the utility model is a rubber ash discharge valve for a cyclone separator. When adjusting the expansion pressure of the flat ash discharge port 9, the knobs 12 at one end of the two adjusting shafts 5 can be manually rotated respectively, so that the screw groove 13 at the other end of the adjusting shaft 5 rotates on the corresponding screw 14, so that the adjusting shaft 5 can also move horizontally in the fixed seat 10, thereby cooperating with the fixing ring 11 to adjust the compression degree of the compression spring 15 on the outer side of the adjusting shaft 5, that is, when the overall length of the compression spring 15 on the outer side of the adjusting shaft 5 becomes shorter, the force acting on the fixing ring 11 becomes greater, so that The greater the pressure exerted by the adjusting shaft 5, the screw 14 and the metal patch 6 on the flat ash discharge port 9, conversely, when the overall length of the compression spring 15 increases, the force exerted on the fixing ring 11 decreases, thereby reducing the pressure exerted by the adjusting shaft 5 on the screw 14, the metal patch 6 and the flat ash discharge port 9. When the dust in the cyclone separator 17 accumulates to a certain weight, the weight of the accumulated dust is used to expand the flat ash discharge port 9, so that the dust can be discharged through the rubber duckbill valve 1 and the flat ash discharge port 9. When the dust is discharged, the flat ash discharge port 9 is automatically closed, and subsequent ash storage and discharge can be carried out.
