Description

Technical Field

[0001] This utility model belongs to the technical field of sealing installation structure of ash discharge valve, and specifically relates to a sealing installation structure of ash discharge valve. Background Technology

[0002] As a core component of material conveying and ash silo discharge systems in industrial production, the ash discharge valve is widely used in power, building materials, chemical, metallurgical, and environmental protection industries. It is particularly indispensable in baghouse dust collectors, electrostatic precipitators, and the storage and conveying of powdery materials such as fly ash, cement, and mineral powder. Its core function is to connect the bottom of the ash silo to the downstream conveying pipeline. Through the rotation of the impeller inside the valve body or the opening and closing of the valve, it achieves quantitative and stable discharge of ash material while maintaining pressure balance within the ash silo. This prevents excessive positive pressure within the silo from causing dust leakage through silo gaps, and also avoids excessive negative pressure from causing a large influx of outside air, which could disrupt the normal operation of the dust collection or conveying system. To improve the connection sealing of the ash discharge valve, an elastic rubber strip is press-fitted at the interface, and bolt assemblies are used for tightening and fixing.

[0003] The existing sealing installation structure of the ash discharge valve installs an elastic rubber strip at the ash discharge interface of the ash discharge valve and then uses a bolt assembly for locking installation. However, it has the following defects: (1) In actual operation, the bolt assembly used for sealing and locking installation is easily affected by the pressure fluctuation in the ash silo, which causes the upper and lower flange bolts of the ash discharge valve to loosen from time to time. The gap between the interfaces of the ash discharge valve cannot be sealed in time, and the ash leakage phenomenon occurs from time to time. Therefore, we propose a sealing installation structure for the ash discharge valve. Utility Model Content

[0004] The purpose of this utility model is to provide a sealing installation structure for an ash discharge valve, so as to solve the problem mentioned in the background art that the sealing installation structure of the ash discharge valve is prone to loosening and thus affects the sealing effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing installation structure for an ash discharge valve, comprising an ash discharge valve body and a connecting pipe, wherein the connecting pipe is disposed at the interface of the ash discharge valve, and an elastic rubber strip is provided between the ash discharge valve body and the connecting pipe; a stud passes through the connection between the ash discharge valve body and the connecting pipe, one end of the stud is threadedly connected to a nut, and the other end of the stud is welded to an assembly cylinder; a movable block is slidably connected inside the assembly cylinder, and an insertion hole is provided at the other end of the movable block; a retaining plate is slidably connected inside the insertion hole; a toothed ring is welded to the outer wall of the nut, and one end of the retaining plate is engaged with the toothed ring.

[0006] Preferably, a tension spring is connected between one end of the movable block and the assembly cylinder.

[0007] Preferably, the surface of the card plate has a side groove, and the inside of the side groove is fixed with a barbed hook and loop fastener by adhesive. The side of the insertion hole is installed with a plug through it, and one end of the plug is fixed with a rough hook and loop fastener by adhesive. The rough hook and loop fastener and the barbed hook and loop fastener are fixed by adhesive.

[0008] Preferably, the side wall of the movable block is provided with a limiting groove, and a limiting block is provided inside the limiting groove. The limiting block is fixed to the inner wall of the assembly cylinder by welding.

[0009] Preferably, the longitudinal section of the card plate is L-shaped, and one end of the card plate has a triangular pyramidal structure.

[0010] Preferably, both the movable block and the assembly cylinder have rectangular cross-sections, and the movable block and the assembly cylinder are fitted together with a clearance.

[0011] Preferably, the longitudinal section of the insert is rectangular, and the cross section of the insert is T-shaped.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) Using the designed toothed ring, assembly cylinder, movable block, and clamping plate, the movable block with the clamping plate is connected to the stud via the assembly cylinder. The toothed ring is installed on the nut. After the stud and nut are screwed together to tighten the sealing structure, the movable block is pulled to adjust the horizontal position of the clamping plate. Then the clamping plate is pulled up and down to adjust the vertical position to ensure that one end of the clamping plate is inserted into the tooth groove of the toothed ring for engagement. The nut and stud are clamped and fixed together to prevent them from loosening due to pressure fluctuations in the ash hopper, which would cause the seal to fail and result in ash leakage. The designed tension spring is used to further secure the connection. The tension spring, in its stretched state, constantly applies elastic traction to the movable block, causing one end of the clamping plate to be locked into the tooth groove of the toothed ring under traction. Through the designed side groove, barbed hook and loop fasteners, rough hook and loop fasteners, and insert blocks, the height of the clamping plate is adjusted. After one end of the clamping plate is locked into the tooth groove of the toothed ring, the insert block is inserted, causing the rough hook and loop fastener at one end of the insert block to adhere to the barbed hook and loop fastener, thereby locking the height position of the clamping plate. Through the designed limiting groove and limiting block, the limiting block blocks inside the limiting groove, thereby limiting the movable block and preventing it from falling out of the assembly cylinder.

The toothed ring 10 is installed on the nut 9. After the stud 4 and nut 9 are screwed together to tighten the sealing structure, the movable block 6 is pulled to adjust the horizontal position of the clamping plate 2. Then, the clamping plate 2 is pulled up and down to adjust the vertical position to ensure that one end of the clamping plate 2 is inserted into the tooth groove of the toothed ring 10 for engagement. The nut 9 and stud 4 are clamped and fixed together to prevent them from loosening due to pressure fluctuations in the ash hopper, which would cause the seal to fail and result in ash leakage. The movable block 6 and the assembly cylinder 5 are fitted with a clearance.

[0022] In this embodiment, preferably, a tension spring 16 is connected between one end of the movable block 6 and the assembly cylinder 5. Through the designed tension spring 16, the tension spring 16 in the stretched state applies elastic traction to the movable block 6 at all times, so that one end of the clamping plate 2 is clamped in the tooth groove of the toothed ring 10 under the traction.
