DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The quick-release pneumatic conveying anti-clogging rotary valve provides two technical solutions:

[0026] like Figure 1 , 3 Table 4 shows a first embodiment: comprising a valve body 1 and a rotating valve core 3, wherein the rotating valve core 3 is installed inside the valve body 1, the top and bottom of the valve body 1 are fixedly connected with a mounting disc 2, and a quick mounting mechanism is provided on the upper mounting disc 2, and the quick mounting mechanism comprises:

[0027] A plurality of locking components 4 are equidistantly arranged on the upper mounting disc 2, the locking components 4 comprising left and right baffles 41, the two baffles 41 are fixedly connected to the bottom of the mounting disc 2, a slide groove 42 is provided inside the two baffles 41, and a slider 43 is slidably connected to the inner surface of the two slide grooves 42, a return spring 44 is fixedly connected between the slider 43 and the top of the inner wall of the slide groove 42, an intermediate rod 45 is fixedly connected between the opposite sides of the two sliders 43, an arc-shaped buckle rod 46 is rotatably connected to the surface of the intermediate rod 45, and the arc-shaped buckle rod 46 is used to buckle the flange on the conveying pipeline, and the surfaces of the intermediate rod 45 on both sides of the arc-shaped buckle rod 46 are sleeved with torsion springs 47, one end of the torsion spring 47 is fixedly connected to the surface of the intermediate rod 45, and the other end of the intermediate rod 45 is fixedly connected to one side of the arc-shaped buckle rod 46.

[0028] The clamping assembly 5 is arranged below the upper mounting disc 2 and is used to increase the clamping force of the arc-shaped buckle rod 46. The clamping assembly 5 includes a ring 51, which is rotatably connected to the bottom of the upper mounting disc 2. A handle 53 is fixedly connected to the annular surface of the ring 51, and a plurality of top blocks 52 are fixedly connected to the bottom of the ring 51 at equal distances. The number of the top blocks 52 is the same as the number of the locking assembly 4, and one side of the top block 52 is formed into an inclined surface by beveling.

[0029] When installing the anti-clogging rotary valve on the conveying pipeline, the operation is performed through a quick installation mechanism. It is only necessary to dock the installation disc 2 with the flange on the conveying pipeline. One person can complete the operation and it can be quickly disassembled, which improves the practicality of the device when in use.

[0030] like Figure 1 and 2 A second embodiment is shown, which mainly differs from the first embodiment in that a sealing assembly 6 is arranged at the opening of the upper mounting disc 2 to ensure sealing after installation. The sealing assembly 6 includes a circular groove 61 opened at the top of the mounting disc 2. The annular inner surface of the circular groove 61 is slidably connected with a mounting ring 62 through a slider and a slide groove. A limiting spring 63 is fixedly connected between the mounting ring 62 and the bottom of the inner wall of the circular groove 61. A circular groove 64 is opened on the top of the mounting ring 62, and a sealing ring 65 is arranged inside the circular groove 64.

[0031] After the anti-clogging rotary valve and the delivery pipeline are installed, the two are sealed by the sealing assembly 6, thereby ensuring the sealing performance of the anti-clogging rotary valve after installation.

[0032] When in use, align the mounting disc 2 with the flange on the conveying pipeline, push the entire rotary valve upward, so that the conveying pipeline flange contacts the arc buckle rod 46, thereby pushing the arc buckle rod 46 to rotate. The rotation of the arc buckle rod 46 allows the flange to enter the interior of the multiple arc buckle rods 46, and the arc buckle rod 46 is reset under the action of the torsion spring 47, so that it is buckled on the top of the flange. At this time, the pre-installation has been completed, and finally the ring 51 is rotated by the handle 53 so that the top block 52 contacts the other end of the arc buckle rod 46, thereby pushing the arc buckle rod 46 to rotate, so that the arc buckle rod 46 is buckled to the top of the flange. When disassembling, the ring 51 is rotated so that the top block 52 is staggered with the arc buckle rod 46. In addition, the edge of the flange opening after installation contacts the sealing ring 65, and presses down so that the limit spring 63 is compressed. The reaction force of the limit spring 63 makes the sealing ring 65 close to the flange to increase the sealing effect.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
