Continuous, quantitative and rotary feeder

Abstract

The invention provides a continuous, quantitative and rotary feeder which comprises a bin, a central shaft, a rotating block, an upper sealing plate and a lower sealing plate. The rotating block is provided with vertically through quantitative holes. The upper sealing plate is provided with a feeding port and is located at the bottom of the bin. The lower sealing plate is provided with a discharging port. The rotating block is arranged between the upper sealing plate and the lower sealing plate and is driven by the central driving shaft to rotate, and the quantitative holes are intermittently communicated with the feeding port or the discharging port in the rotating process of the rotating block. The phenomena of port blockage and material accumulation do not occur, the continuous, quantitative and rotary feeder can perform accurate feeding, effectively prevents moisture from entering the material bin, effectively prevents materials from being affected with damp and is simple in structure, convenient to manufacture, low in cost and low in failure rate.

Description

[0001] 【Technical field】 [0002] The invention relates to a feeder. [0003] 【Background technique】 [0004] In the field of sewage treatment, solid-liquid separation of sewage is required, which is to add flocculant into sewage to make sewage coagulate into solids, and then perform solid-liquid separation. The flocculant (also called agent) needs to be mixed with water before use. When mixing, it has a certain ratio of raw materials and a uniform mixing requirement. Therefore, it is necessary to rely on the feeder to accurately feed the mixer. [0005] Such as figure 1 As shown, the traditional feeder has a material bin 1', a feeding screw 2', and a vibrator. When the feeding screw 2' rotates, by adjusting the rotation speed of the feeding screw 2', the medicine can be quantitatively output. to Instant Pot 3'. But this feeder has the following disadvantages: [0006] 1. Because the medicine is easy to be affected by moisture, it is easy to block the screw when it is wet, ...

AI Technical Summary

Problems solved by technology

[0006] 1. Because the medicine is easy to be affected by moisture, it is easy to block the screw when it is wet, resulting in inaccurate measurement;

[0007] 2. Moisture is also easy to enter through the gap of the conveying screw, making the material damp;

[0008] 3. In order to prevent materials from being piled up, a vibrator needs to be installed, which will lead to complex equipment, cumbersome manufacturing, high cost and high failure rate
