Description

Technical Field

[0001] The utility model belongs to the technical field of screening equipment and accessories thereof, in particular to a novel sealing joint device of a floating frame of a vibrating relaxation screen. Background Art

[0002] There are many kinds of screening equipment now, and vibrating flap screen is one of the representative screening equipment. Vibrating flap screen is widely used in the screening operation of fine-grained materials in the coal industry. This type of screen has the characteristics of high screening rate, good screening effect and excellent anti-blocking performance, and is therefore recognized by the majority of users. It drives the screen body to vibrate through the vibration motor, and then when the material falls on the screen body, it will be shaken and thrown by the vibration to achieve the screening effect.

[0003] A Chinese patent application (or patent) with publication number CN208786874U discloses a synchronously driven vibrating tension screen, comprising an active screen frame, a floating screen frame, a polyurethane screen surface, a vibration exciter, a drive device, a support device, and a synchronization device. The screen utilizes a dual-exciter structure, with two exciters positioned perpendicular to the screen surface, one above and one below. The two exciters are each connected to a diverter via a petal-type coupling. The diverter is connected to a universal joint at one end and to a motor via an elastic pin coupling at the other. The motor drives the diverter, which indirectly drives the two exciters, causing them to vibrate in opposite directions. The inertial forces of the two exciters cancel each other out perpendicular to the screen surface, while their inertial forces parallel to the screen surface are combined. The screen only moves in a linear motion parallel to the screen surface. This results in low overall vibration, strong stability, a long lifespan, high screening efficiency, and low dynamic load on the foundation.

[0004] The above-mentioned synchronously driven vibrating relaxation screen is provided with an active screen frame and a floating screen frame. The bottom of the active screen frame is provided with a square opening for installing the floating screen frame, that is, the floating screen frame is installed inside the active screen frame, and there is a certain installation gap between them. At the same time, due to the gap between the two screen frames, the material will flow out of the gap, thereby causing the problem that the unscreened material enters the screened material; and the active screen frame and the floating screen frame are arranged alternately, and because the floating screen frame and the active screen frame are subjected to different vibrations, the fluctuation amplitudes are also different, which causes the slot between the two to intermittently increase or decrease due to the progress of the screening work, which also causes the problem that the sealing operation between the two screen frames is difficult to achieve. To this end, we provide a new type of vibrating relaxation screen floating frame sealing joint device to solve the above-mentioned problems. Utility Model Content

By utilizing a hard plate, rubber plate one, rubber plate two and rubber plate three, the gap between the floating frame and the active frame can be blocked and shielded to prevent material from flowing out of the gap. By utilizing elastic parts, elastic rods, rotating part one and rotating part two, the device can better cooperate with the floating frame and the active frame for vibration screening, thereby solving the problems of the above-mentioned synchronously driven vibrating relaxation screen.

[0011] The utility model is further configured such that the rubber plate three is configured in a hollow structure, and connecting rings are bonded to both ends of the rubber plate three, and the rubber plate three is connected to the hard plate through the connecting rings.

[0012] The utility model is further configured such that a rotation groove is provided on an outer wall of the hard plate facing the rubber plate three, and rotation holes are provided on the left and right side walls of the rotation groove, and a rotating member one is provided in the rotation groove.

[0017] The utility model provides a connecting assembly, which includes a rubber plate 1, a rubber plate 2 and an elastic member for connecting the straight plate and the hard plate. The rubber plate 1, the rubber plate 2 and the elastic member are elastic themselves and can be stretched and elastically deformed when they are subjected to force.

Two elastic rods are provided in the rubber plate three. The elastic rods are used to extend or retract in coordination with the fluctuations of the floating frame and the active frame, so that the device can restore to its initial state when the vibrating relaxation screen stops. At the same time, the two elastic rods are connected by a rotating member two, and the other axial end of the elastic rod is connected to the hard plate through a rotating member one, thereby allowing the two elastic rods and the elastic rod and the hard plate to rotate at a certain angle in the vertical direction, so that they can better cooperate with the floating frame and the active frame of the vibrating relaxation screen to perform screening work.

[0029] Specifically, a connecting frame 101 for connecting rubber plate 1 202 and rubber plate 2 203 is adhered to the outer wall of the hard plate 1, and a circular hole 102 for installing the elastic member 205 is opened inside the connecting frame 101, and a straight plate 201 is also adhered to the other end of the rubber plate 1 202 and the rubber plate 2 203, and the straight plate 201 is connected to the side wall of the floating frame through a connecting bolt 204.

[0031] The operation process of this embodiment is as follows: when in use, the connecting bolts 204 are removed, and the straight plate 201 is attached to the side wall of the floating frame. Then, the connecting bolts 204 are inserted from one side of the floating frame and exit from one side of the straight plate 201 to achieve the effect of fixing the straight plate 201 to the side wall of the floating frame. When the floating frame vibrates, the rubber plate 1 202, the rubber plate 203 and the elastic member 205 all vibrate accordingly. The rubber plate 1 202, the rubber plate 203 and the elastic member 205 are all elastic and can be deformed in coordination with the vibration action of the vibrating screen. Example 2

[0032] See also Figure 4 On the basis of Example 1, a rubber plate 3 is further provided, through which the two hard plates 1 are connected. By utilizing the rotating member 1 302, the elastic rod 303 and the rotating member 2 304, when the rubber plate 3 is subjected to a vibration force, the hard plates 1 on both sides thereof can also vibrate with different amplitudes.

[0033] Specifically, connecting rings 301 for connecting to the hard board 1 are adhered to both ends of the rubber plate 3, and a rotating groove 103 for installing the rotating part 1 302 is provided on the side wall of the hard board 1. A rotating hole 103a for rotating connection to the rotating shaft 1 302b is provided on the inner wall of the rotating groove 103. The rotating shaft 1 302b is rotatably connected to a rod seat 302a, and the rod seat 302a is connected to one end of the elastic rod 303. The other end of the elastic rod 303 is also installed with a rotating part 2 304, and the elastic rod 303 is rotatably connected to another elastic rod 303 through the rotating part 2 304.

The rod sleeve 2 304c is fixedly sleeved on the small round rod 303c of the other elastic rod 303.

[0035] The operating process of this embodiment is as follows: when in use, the two ends of the rubber plate three 3 are respectively connected to different hard plates 1, and the two hard plates 1 are respectively used to connect the floating frame and the active frame, thereby achieving the effect of closing the gap between the floating frame and the active frame. When the active frame or the floating frame is vibrated and vibratory screening is performed, the elastic rod 303 and the rubber plate three 3 will be stretched or compressed accordingly, so that the gap between the active frame and the floating frame is always in a closed state, and through the rotating part 1 302 and the rotating part 2 304, when the floating frame and the active frame are subjected to force vibration, the two elastic rods 303 and the elastic rod 303 and the hard plate 1 can be rotated at a certain angle in the vertical direction, so that they can better cooperate with the floating frame and the active frame of the vibrating relaxation screen to perform screening work.
