Proportion-adjustable feeding device and mixing machine

Abstract

A proportion-adjustable feeding device is disclosed in the invention, and comprises a machine frame, the machine frame comprises a base, a supporting column and a top plate, the base is further provided with a driving cylinder and at least two quantifying mechanisms, the driving cylinder comprises a driving cylinder base and a driving rod, and each quantifying mechanism comprises an upper sliding block, a lower sliding block, a cylinder body and a piston rod. Each cylinder body comprises a material storage cavity, a feeding port, a discharging port and a reversing valve, and the lower end of the piston rod is arranged in the material storage cavity. The quantifying mechanisms with the adjustable position are utilized, and then the strokes of the piston rods are different when the quantifying mechanisms are located at different positions, so different feeding amounts are obtained, and finally proportion adjustment is achieved. Due to the fact that the multiple quantifying mechanisms can be placed on the same machine frame, the multiple quantifying mechanisms can achieve proportional adjustment through the same mechanism, and the structure is simpler. Meanwhile, the invention further provides a mixing machine.

Description

technical field [0001] The invention relates to chemical production equipment, especially mixing equipment for feeding materials in fixed proportions. Background technique [0002] In chemical processing and production, it is often necessary to stir and mix various fluid raw materials. In some processing techniques, the proportion of raw materials is fixed, while in some processes, the ratio of raw materials needs to be adjusted frequently. In order to achieve accurate mixing in proportion, metering pumps are used in the prior art to achieve quantitative feeding, but the adjustable range of the metering pumps in the prior art is not large, and the adjustment mechanism is complicated. , just need a plurality of adjusting mechanisms, thereby making the structure of the whole feeding device more complicated, and the purchase cost of corresponding equipment is higher. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide...
