DETAILED DESCRIPTION
[0019] The utility model will be further described below in combination with the drawings and embodiments.
[0020] Please refer to Figs. 1 to 3The quick-open end cover sealing structure of low-pressure container is designed compactly, mainly composed of a cylinder 19, an end cover 10 and a clamp 7 connecting the two. The edge of the end cover 10 is provided with a first wedge-shaped ring flange 8, and the lower plane and the upper inclined plane form a unique sealing surface. Correspondingly, the upper edge of the cylinder 19 is equipped with a second wedge-shaped ring flange 9, and the upper plane and the lower inclined plane are matched with the first wedge-shaped ring flange 8, and a rubber sealing ring 22 is ingeniously embedded between the two planes to ensure excellent sealing performance.
[0021] The clamp 7 is composed of a left clamping plate 7a and a right clamping plate 7b, both of which are designed as a side "U" shaped cross section, with a wide mouth and a narrow bottom to tightly clamp the flange. The two ends of the left clamping plate 7a are respectively fixed with a support ear 15 and a locking ear 5, and the right clamping plate 7b is correspondingly provided with a support ear 16 and a locking ear 1. The support ear 15 and the support ear 16 are hinged by a bolt shaft 2, and the bolt shaft 2 is further stably fixed on the cylinder 19 by a support plate 17, providing a reliable support point for the clamp.
[0022] In terms of locking mechanism, one end of the locking ear 5 is hinged to the connecting plate 2 through the bolt shaft 1a, and one end of the locking ear 1 is connected to the locking wrench 6 through the bolt shaft 1b. The middle part of the locking wrench 6 is further hinged to the end of the connecting plate 2 through the pin shaft 3, forming a flexible and firm locking system. By rotating the locking wrench 6 clockwise or counterclockwise, the opening and closing of the left clamping plate 7a and the right clamping plate 7b can be easily controlled, so as to realize the quick opening and tight closing of the end cover 10.
[0023] In addition, in order to facilitate operation and maintenance, the side wall of the cylinder 19 is further fixed with a lifting arm support 18, and a rotating arm 13 is rotatably connected to the lifting arm support 18. The top of the end cover 10 is provided with a lifting arm lead screw 12, and the top end of the lifting arm lead screw 12 is equipped with a lifting arm hand wheel 11. By rotating the lifting arm hand wheel 11, the lifting arm lead screw 12 can be driven to rise or fall, and then the end cover 10 can be easily lifted or lowered through the rotating arm 13.
[0024] It is worth mentioning that the filter element 20 is also installed in the cylinder 19 to meet the specific process requirements. At the same time, four supporting plates 21 are provided on the side wall of the cylinder 19, which are evenly distributed on the same plane, and play an effective supporting and limiting role on the left clamping plate 7a and the right clamping plate 7b in the open state. This not only prevents the clamp from being misaligned when it is opened, but also ensures that the clamp can remain in a horizontal position when it is locked next time, thereby greatly simplifying the operation process and improving the work efficiency.
[0025] In Fig. 1The edge of the end cover 10 is provided with a first wedge-shaped ring flange 8, the lower surface of which is flat and the upper surface is inclined. A second wedge-shaped ring flange 9 is provided on the cylinder 19, the upper surface of which is flat and the lower surface is inclined. A rubber sealing ring 22 is provided between the two flat surfaces to enhance the sealing effect. The radial section of the left and right clamping plates 7a and 7b is in the shape of a side "U" with a large opening and a small base.
[0026] As shown in Fig. 2 , 3 , the right ends of the left and right clamping plates 7a and 7b are connected through the support ears 15 and 16 and the bolt shaft 14, and the left ends are hingedly connected through the locking ears 4, the bolt shaft 1a, the locking ears 5, the pin shaft 3, the bolt shaft 1b, the connecting plate 2, and the locking wrench 6.
[0027] The left and right clamping plates 7a and 7b are pivoted on the bolt shaft 14, and the locking wrench 6 can be rotated clockwise to open them. The first wedge-shaped ring flange 8 of the end cover 10 is separated from the "U"-shaped opening of the left and right clamping plates 7a and 7b. When the locking wrench 6 is moved in the counterclockwise direction, the two half-ring-shaped left and right clamping plates 7a and 7b tightly clamp the first and second wedge-shaped ring flanges 8 and 9 together, which can withstand a pressure of 1.5 MPa. A hoist arm support 18 is provided on the upper right part of the cylinder 19, and a hoist arm lead screw 12 is provided on the middle part of the upper part of the end cover 10, which is connected through the hoist arm hand wheel 11 and the rotating arm 13. Four supporting plates 21 are provided on the cylinder 19 corresponding to the positions of the left and right clamping plates 7a and 7b. When it is necessary to open the end cover 10, the locking wrench 6 is rotated clockwise to open the left and right clamping plates 7a and 7b, then the end cover 10 is lifted by rotating the hoist arm hand wheel 11 through the hoist arm lead screw 12, and the rotating arm 13 is rotated to one side, so that the end cover 10 can be opened, and the filter element 20 inside the container can be replaced or maintained. The four supporting plates 21 support and limit the opening of the left and right clamping plates 7a and 7b, and are evenly distributed on the same plane to prevent the left and right clamping plates 7a and 7b from being misaligned when they are opened, and to keep the horizontal position of the left and right clamping plates 7a and 7b unchanged when they are locked next time.
[0028] The locking ears 4 and 5, the connecting plate 2, and the locking wrench 6 are all connected through the pin shaft 3 and the bolt shafts 1a and 1b. The lower ends of the support ears 15 and 16 and the bolt shaft 14 are fixed to the cylinder 19 through the supporting plate 17.
[0029] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which are made by using the content of the present application specification and drawings, are also included in the patent protection scope of the present application.
