Description

Technical Field

[0001] This utility model relates to the field of converter sealing technology, specifically to a sealing device for an activated carbon converter. Background Technology

[0002] Activated carbon converters often refer to a type of production equipment used to manufacture activated carbon. Activated carbon is a porous adsorbent material that has undergone special processing. Due to its unique pore structure, it has strong adsorption properties and is widely used in water treatment, air purification, food industry, medicine, chemical industry and many other fields. The carbon converter is a device that carbonizes raw materials at high temperatures using physical or chemical methods, and then produces activated carbon through oxidation, water washing, drying and other processes.

[0003] In the existing technology, most converter sealing connections use flange connections. Since the flange faces are usually sealed by sealing rings, the gas pressure load inside the activated carbon converter will cause the flange faces to move, resulting in poor sealing effect and causing the gas generated inside the activated carbon converter to escape.

[0004] Therefore, a sealing device for activated carbon converters is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing device for activated carbon converters in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An activated carbon converter sealing device includes a support base and an activated carbon converter body fixedly installed on the top of the support base. Both ends of the activated carbon converter body are provided with flanges. The end face of the flanges is fitted with pipe connection flanges, and bolts are provided in the pipe connection flanges and flanges. The end faces of the flanges and pipe connection flanges are provided with active sealing components and passive sealing components to seal the end faces of the flanges and pipe connection flanges.

[0008] Furthermore, the end face of the flange is provided with a first threaded groove, and the end face of the pipe connection flange is provided with a second threaded groove, and the internal threads of the first threaded groove and the second threaded groove are inserted with external threaded stepped collars.

[0009] Furthermore, the active sealing assembly includes annular grooves respectively opened on the end faces of the flange and the pipe connection flange, a sealing ring is placed inside the annular groove, and a cavity is opened inside the sealing ring, and several sets of support rings are embedded in the sealing ring.

[0010] Furthermore, the passive sealing assembly includes an annular groove on the end face of the flange, an airtight groove corresponding to the annular groove on the end face of the pipe connecting flange, a sealing ring inside the airtight groove, an L-shaped gas channel on the surface of the pipe connecting flange and the end face of the airtight groove, an air injection port on the surface of the pipe connecting flange and corresponding to the end of the L-shaped gas channel, and a valve on the surface of the air injection port.

[0011] Furthermore, the cross-section of the external threaded stepped collar is convex, and the outer walls at both ends of the external threaded stepped collar are respectively fitted to the inner walls of the flange and the pipe connection flange.

[0012] Furthermore, the sealing ring has an elliptical cross-section, is made of elastic rubber material, and has an internal support ring made of spring steel.

[0013] The beneficial effects of this utility model are as follows:

[0014] The activated carbon converter body is supported and placed by a support base. The pipe connection flange and flange are fixedly connected by bolts. The active sealing component has an elastic structure, which can be compressed to actively seal the gap between the pipe connection flange and flange. By applying gas pressure to the passive sealing component, the sealing part of the passive sealing component moves under pressure to passively seal the gap between the pipe connection flange and flange.

[0015] After the external threaded stepped collar is inserted into the internal thread of the first threaded groove, the second threaded groove on the end face of the pipe connection flange is threaded onto the surface of the external threaded stepped collar, which increases the strength of the connection between the flange and the pipe connection flange, and at the same time increases the sealing performance of the gap at the joint between the flange and the pipe connection flange.

[0025] like Figures 1 to 4As shown, an activated carbon converter sealing device includes a support base 1 and an activated carbon converter body 2 fixedly installed on the top of the support base 1. Both ends of the activated carbon converter body 2 are provided with flanges 3, and pipe connection flanges 4 are fitted to the end faces of the flanges 3. Bolts 5 are installed inside the pipe connection flanges 4 and flanges 3. Active sealing components 7 and passive sealing components 8 are provided on the end faces of the flanges 3 and pipe connection flanges 4 to seal the end faces of the flanges 3 and pipe connection flanges 4. More specifically, the activated carbon converter body 2 is supported and placed by the support base 1, and the pipe connection flanges 4 and flanges 3 are fixedly connected by bolts 5. The active sealing component 7 has an elastic structure, allowing it to be compressed to actively seal the gap where the pipe connection flanges 4 and flanges 3 are fitted. By applying gas pressure to the passive sealing component 8, the sealing part of the passive sealing component 8 moves under pressure, achieving passive sealing of the gap where the pipe connection flanges 4 and flanges 3 are fitted.

[0026] The end face of flange 3 has a first threaded groove 31, and the end face of pipe connecting flange 4 has a second threaded groove 41. An externally threaded stepped collar 6 is inserted into the internal threads of both the first and second threaded grooves 31. More specifically, after the externally threaded stepped collar 6 is inserted into the internal threads of the first threaded groove 31, the surface threads of the second threaded groove 41 on the end face of pipe connecting flange 4 are fitted onto the externally threaded stepped collar 6. This increases the connection strength between flange 3 and pipe connecting flange 4, and simultaneously improves the sealing performance of the gap at the mating point of flange 3 and pipe connecting flange 4.

[0027] The active sealing assembly 7 includes annular grooves 701 corresponding to the end faces of the flange 3 and the pipe connection flange 4. A sealing ring 702 is placed inside the annular groove 701, and a cavity 703 is formed inside the sealing ring 702. Several sets of support rings 704 are embedded in the sealing ring 702. More specifically, by installing the sealing ring 702 in the annular grooves 701 on the end faces of the flange 3 and the pipe connection flange 4, and connecting the pipe connection flange 4 and the flange 3 with bolts 5, the sealing ring 702 and the support rings 704 are compressed. The sealing ring 702 is compressed, and the elasticity of the support rings 704 makes the sealing ring 702 fit tightly against the surface of the annular groove 701, thus achieving active sealing.

[0028] The passive sealing assembly 8 includes an annular groove 801 on the end face of the flange 3, an airtight groove 802 on the end face of the pipe connecting flange 4 corresponding to the annular groove 801, a sealing ring 803 movable in the airtight groove 802, an L-shaped gas passage 804 on the surface of the pipe connecting flange 4 and the end face of the airtight groove 802, an air injection port 805 on the surface of the pipe connecting flange 4 and corresponding to the end of the L-shaped gas passage 804, and a valve 806 on the surface of the air injection port 805. More specifically, the flange 3 and the pipe connection flange 4 are fixed together by bolts 5, so that the airtight groove 802 and the annular groove 801 correspond. The air injection port 805 is opened and the air pump is connected to the air injection port 805. The air pump pressurizes the inside of the airtight groove 802 through the air injection port 805 and the L-shaped gas channel 804, so that the sealing ring 803 moves in the airtight groove 802 and the end of the sealing ring 803 is inserted into the inside of the annular groove 801, thereby passively sealing the gap between the flange 3 and the pipe connection flange 4. When disassembling, the air pump is used to evacuate the airtight groove 802 through the air injection port 805 and the L-shaped gas channel 804, so that the sealing ring 803 moves in the opposite direction in the airtight groove 802 and is retracted into the airtight groove 802. Then the valve 806 is closed, at which time the sealing ring 803 is located in the airtight groove 802.

[0029] The external threaded stepped collar 6 has a convex cross-section, and the outer walls at both ends of the external threaded stepped collar 6 are fitted to the inner walls of the flange 3 and the pipe connection flange 4, respectively. More specifically, by fitting the outer walls at both ends of the external threaded stepped collar 6 to the inner walls of the flange 3 and the pipe connection flange 4, the gap between the flange 3 and the pipe connection flange 4 is sealed.

[0030] The sealing ring 702 has an elliptical cross-section and is made of elastic rubber material. Its internal support ring 704 is made of spring steel. More specifically, by using elastic materials for both the sealing ring 702 and the support ring 704, the sealing ring 702 can be compressed. After compression, the surface of the sealing ring 702 fits tightly against the surface of the annular groove 701 under its own elastic force.

[0031] In summary: The activated carbon converter body 2 is supported and placed by the support base 1, and the pipe connection flange 4 and flange 3 are fixedly connected by bolts 5. The active sealing component 7 has an elastic structure, which can be compressed to actively seal the gap between the pipe connection flange 4 and flange 3. By applying gas pressure to the passive sealing component 8, the sealing part of the passive sealing component 8 moves under pressure, thereby passively sealing the gap between the pipe connection flange 4 and flange 3.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
