Horizontal type vibratory stirring machine with spiral vibration exciter

Abstract

The invention discloses a horizontal type vibratory stirring machine with a spiral vibration exciter. The horizontal type vibratory stirring machine comprises a vibration power device, a stirring power device, a stirring drum, a stirring device, a frame and the spiral vibration exciter. The stirring device is arranged in the stirring drum, the two ends of the stirring device penetrate through holes in the two end covers of the stirring drum to be supported to the frame, the spiral vibration exciter is arranged at the center of the stirring device, the spiral vibration exciter is connected witha vibratory power device through a connecting shaft, and one end of the stirring device is connected with the stirring power device; the spiral vibration exciter is a polygonal shaft with the cross section being provided with N smooth bulges, the spiral lead angle is 0-90 degrees, and N is larger than or equal to 1; and the vibration excitation frequency can be changed by changing the number of the bulges, the vibration excitation amplitude can be adjusted by changing the height of each bulge, the material moving direction can be changed by changing the spiral lead angle of the spiral vibration exciter, and different vibration effects are achieved. According to the horizontal type vibratory stirring machine with the spiral vibration exciter, the defects of an eccentric type vibration exciter are overcome, the horizontal type vibratory stirring machine and the stirring device jointly act, vibration stirring is achieved, and improving of the stirring quality and efficiency is facilitated.

Description

technical field [0001] The invention belongs to the field of forced stirring equipment, in particular to a horizontal vibrating mixer with a spiral vibrator. Background technique [0002] Cement concrete occupies an extremely important position in modern engineering construction, and is widely used in road traffic, bridge tunnels, housing construction, etc. For this reason, the performance of cement concrete must meet the increasingly high performance requirements in current engineering construction. A large number of studies have shown that the interface between the aggregate and cement stone inside the concrete is a weak link in the concrete, and improving the interface bond strength by strengthening the mixing process or optimizing the mixing process is one of the important ways to improve the strength of concrete. At present, the mixer widely used in engineering applications at home and abroad is a forced mixer. Its working principle is to make the raw materials circula...

AI Technical Summary

Problems solved by technology

The exciter of the existing vibrating mixer adopts the eccentric principle to generate vibration, the sealing effect of the shaft end is not good, the bearing is not in a good state of stress, and materials are easily mixed in between the shaft and the bearing, and it is easy to generate heat under high-speed rotation, which aggravates the bearing At the same time, the actual working conditions are complicated, the force of the exciter is not easy to balance when it is working, the vibration energy cannot fully act on the work object and it is easy to generate noise pollution, which makes the construction conditions on site harsh, which does not meet the requirements of our country. The current environmental protection requirements may even affect the health of construction workers
