Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic vibrators, in particular to a shock-absorbing and wear-resistant electromagnetic vibrator with a cooling device. Background Art

[0002] The electromagnetic silo wall vibrator is a special equipment used to prevent and eliminate blockages such as material silos and arching in silos, tanks, chutes and tubular channels. It can also be used as a vibration source for vibrating feeders, vibrating conveyors, vibrating hoppers, vibrating chutes, etc. When a DC voltage is applied to the coil in the electromagnetic hammer vibrator, a magnetic field will be generated around the coil, and the vibrating rod will be attracted and lifted under the action of the magnetic field force. When it is lifted to a certain height, the coil will be immediately de-energized and the magnetic field will disappear. At this time, the vibrating rod will fall freely under the action of gravity and hit the vibrating rod. The vibrating force generated is transmitted to the internal cathode and anode systems or airflow distribution devices through the vibrating rod, thereby achieving the purpose of vibrating and cleaning.

[0003] For example, a patent document with the announcement number CN219424621U discloses an electromagnetic rapper, comprising: a rapper body, comprising a first rapping assembly and a second rapping assembly arranged at intervals, the first rapping assembly comprising a first sleeve and a first rapping rod arranged in the first sleeve; the second rapping assembly comprising a second sleeve and a second rapping rod arranged in the second sleeve, the first rapping rod and the second rapping rod being coaxially arranged; the first sleeve is grounded; a rapping assembly, connected to the end of the first rapping rod away from the second rapping rod, used for rapping the anode plate of the dust collector, the rapping assembly is connected to the first sleeve and grounded through a first grounding assembly; a second grounding assembly, one end of the second grounding assembly is connected to the first rapping rod, and the other end is connected to the first sleeve, the electromagnetic rapper arranges the second grounding assembly between the first rapping rod and the first sleeve, and the floating potential generated by the collision between the first rapping rod and the second rapping rod is discharged to the ground through the second grounding assembly, thereby reducing the situation where the floating potential causes a circuit short circuit in the electromagnetic rapper.

[0004] The above-mentioned electromagnetic rapper is connected to the junction box of the second sleeve through electric wires, and the junction box is connected to the electromagnetic coil in the second sleeve. When the power supply device energizes the electromagnetic coil in the second sleeve, direct current will be generated in the electromagnetic coil. The magnetic force generated by the direct current will drive the second rapping rod in the second sleeve to be lifted to a certain height, and then the power is cut off. The magnetic force in the second sleeve disappears, and the second rapping rod naturally falls due to gravity and hits the first rapping rod in the first sleeve to generate a rapping force. The rapping force is transmitted to the rapping head through the insulating rod, and the rapping head hits the anode plate or cathode frame at the bottom to complete a rapping step. A large amount of heat will be generated when the rapping rod is rapping, and the heat will be transmitted to the rapping device body through the rapping rod, which will affect the normal operation of the rapping device body. For this reason, we propose a shock-absorbing and wear-resistant electromagnetic rapper with a cooling device. Utility Model Content
