[0030] Embodiments

[0031] Reference Figures 1-5 The present embodiment provides an anti-clogging air lock, comprising a casing 110, a discharging assembly 120 and a vibration assembly 130. The casing 110 comprises a discharging bin 111. The discharging assembly 120 comprises a hollow rotating drum 121 movably connected in the discharging bin 111. The outer wall of the hollow rotating drum 121 is provided with a plurality of blades 122 in annular array around the axis of the hollow rotating drum 121, and the end of the blade 122 is attached to the inner wall of the discharging bin 111. The vibration assembly 130 comprises a vibrator 131 arranged in the hollow rotating drum 121. The vibrator 131 is connected with a plurality of vibration pieces 132 penetrating through the hollow rotating drum 121. At least one vibration piece 132 is arranged between adjacent blades 122.

[0032] In the present embodiment, the conventional rotor is improved into the structure of the hollow rotating drum 121, and the vibrator 131 is arranged in the hollow rotating drum 121. When the hollow rotating drum 121 rotates to drive the blade 122 to discharge the material, the plurality of vibration pieces 132 can be vibrated simultaneously under the action of the vibrator 131. Since at least one vibration piece 132 is arranged between adjacent blades 122, the material in the lattice space between each adjacent blade 122 can be excited. The excitation of the vibration piece 132 to the material is ensured, and the risk of clogging of the material at the position of the blade 122 and the hollow rotating drum 121 is reduced, thereby improving the discharging effect.

[0033] It should be noted that the vibrator 131 can use an existing exciter or a vibration motor or other devices that can generate an excitation effect. The exciter is a device attached to some machines and equipment to generate excitation force. It is an important component of mechanical vibration. The exciter can make the excited object obtain a certain form and size of vibration. The vibration motor is provided with a set of adjustable eccentric blocks at both ends of the rotor shaft. The excitation force is obtained by using the centrifugal force generated by the high-speed rotation of the shaft and the eccentric blocks.

[0034] As an optional implementation, the hollow rotating drum 121 can adopt a detachable structure, which comprises a drum body and end covers detachably connected to both sides of the drum body through fasteners such as screws, facilitating assembly and disassembly, and when the internal vibrator 131 fails, the hollow rotating drum 121 can be easily disassembled to remove the vibrator 131 for repair or replacement.

[0035] As an optional implementation, the vibration plate 132 has a gap with the blade 122, so that the vibration of the vibration plate 132 mainly acts on the material, and at the same time, the gap can leave a certain vibration space for the amplitude of the vibration plate 132, ensuring the vibration effect on the material.

[0036] As an optional implementation, the hollow rotating drum 121 is provided with a movable groove matched with the corresponding vibration plate 132, and the movable groove is sealingly provided with an elastic sealing sleeve 140 sleeved on the corresponding vibration plate 132.

[0037] In the embodiment, the vibration plate 132 needs to penetrate the hollow rotating drum 121, and the movable groove can penetrate the vibration plate 132, and considering the problem of material leakage into the hollow rotating drum 121 through the movable groove, the elastic sealing sleeve 140 is also filled in the movable groove here to prevent material leakage, and the elastic sealing sleeve 140 has a certain elastic effect and can cooperate with the vibration effect of the vibration plate 132 without affecting the vibration effect, thereby meeting the feasibility of the vibration effect. The elastic sealing sleeve 140 can be made of rubber material to meet the use requirements.

[0038] As an optional implementation, the thickness direction of the vibration plate 132 is parallel (such as Figure 1 ) or perpendicular (such as Figure 2 ) to the axis of the hollow rotating drum 121, and the arrangement of the vibration plate 132 is not limited, which is generally parallel or perpendicular.

[0039] As an optional implementation, the vibration plate 132 can adopt a flat plate or a wave plate structure, which is better for exciting the material.

[0040] As an optional implementation, a plurality of connecting columns 150 are connected between the outer wall of the vibrator 131 and the inner wall of the hollow rotating drum 121, and the plurality of connecting columns 150 are all elastic.

[0041] In the embodiment, the vibrator 131 can be suspended in the hollow rotating drum 121 by the plurality of connecting columns 150, and the vibrator 131 can generate vibration on the connecting columns 150. The connecting columns 150 are elastic, so that the vibrator 131 can better transmit the vibration frequency to the vibrating sheet 132, and the connecting columns 150 also transmit part of the vibration frequency to the hollow rotating drum 121, further improving the exciting effect on the material. The connecting columns 150 can also be made of rubber.

[0042] As an optional embodiment, the hollow rotating drum 121 is connected with a bearing seat 160 and a driving motor 170 at two ends through movable shafts, respectively. The bearing seat 160 and the driving motor 170 are arranged on the two outer sidewalls of the discharge bin 111. The driving motor 170 can drive the hollow rotating drum 121 to rotate, and the bearing seat 160 can support the hollow rotating drum 121 and cooperate with the hollow rotating drum 121 to rotate.

[0043] It should be noted that the driving motor 170 can be a stepping motor or a servo motor. The stepping motor is an electric motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. Every input pulse signal can make the rotor rotate an angle or move forward by a step. The output angular displacement or linear displacement is proportional to the input pulse number, and the rotation speed is proportional to the pulse frequency. The servo motor can control the speed and has very accurate position accuracy. It can convert the voltage signal into torque and speed to drive the control object. Both the above-mentioned motors can meet the use requirement of accurately controlling the rotation speed.

[0044] As an optional embodiment, the machine shell 110 further comprises a feeding hopper 112 and a discharging hopper 113. The feeding hopper 112 is connected to the top of the discharge bin 111, and the discharging hopper 113 is connected to the bottom of the discharge bin 111. The material can enter the discharge bin 111 from the feeding hopper 112 and finally quantitatively discharge from the discharging hopper 113.

[0045] As an optional embodiment, the feeding hopper 112 and the discharging hopper 113 are both provided with a connecting flange 114 at the other end. The entire air lock can be assembled into the equipment for conveying the material through the connecting flange 114, which has strong versatility.

[0046] It should be noted that the connecting flange 114 can be integrally formed with the feeding hopper 112 and the discharging hopper 113 by welding, which is structurally firm and not easy to loosen, and meets the use requirement.

[0047] The above is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields is also included in the patent protection scope of the present application.
