Problems solved by technology

When one or two screw rods rotate in the silo, due to the circular motion of the screw rods, it is easy to cause the dry powder agent to bridge and block the cavity of the silo. This phenomenon is also called "shelf", which leads to uneven feeding. , or even no cutting and other issues
The quality of water treatment will be seriously affected due to inaccurate dosage of dry powder

Embodiment Construction

[0010] The present invention is described in detail below in conjunction with accompanying drawing:

[0011] figure 1 Shows the case where the quantitative delivery unit consists of one or two screw rods. When one or two screw rods 6 rotate in the feeder box 5, since the screw rods 6 cannot clean the powder sticking to the screw blades during the working process, it is easy for the dry powder agent to bridge to form the silo cavity 11. The phenomenon is also called "shelf", which leads to problems such as uneven cutting or even no cutting. The quality of water treatment will be seriously affected due to the inaccurate quantity of the dry powder agent.

[0012] figure 2 It is a schematic diagram of the multi-screw high-precision quantitative feeding device of the present invention. The screw blades of the screw feeding mechanism have the same helix angle and blade diameter, and the rotation direction of the adjacent screw rods 6 is opposite, and a part is embedded in each o...

Abstract

The invention relates to a multi-spiral high-precision quantitative feeding device, which comprises a base, wherein a motor is sequentially connected with a gearcase on the base through a speed reducer; and one end of a spiral feeding mechanism arranged at the lower part of a feeding case is connected with a driving shaft in the gearcase, and the other end of the spiral feeding mechanism extends into a discharging mechanism. The multi-spiral high-precision quantitative feeding device is characterized in that at least three spiral rods are arranged in the spiral feeding mechanism in parallel, spiral blades of the spiral rods are consistent in spiral angle and diameter, and every two adjacent spiral rods are different in rotating direction and are embedded to each other. According to the invention, five spiral rods are arranged in the spiral feeding mechanism in parallel. The multi-spiral high-precision quantitative feeding device has the beneficial effects that a dry powder agent with unchanged dosage is conveyed after being distributed to a plurality of spiral rods, so that the powder agent in a storage bin can be prevented from being crosslinked and the problems of uneven feeding, even no feeding and the like are solved, and therefore high-precision quantitative feeding of the dry powder agent is achieved.

Description

technical field [0001] The design of the present invention relates to a powder or granular material conveying equipment. Background technique [0002] As an important means of water treatment process, various dry powder configuration and dosing play a very important role in the whole water treatment process. Widely used in municipal water supply and sewage treatment, also suitable for petroleum, chemical, paper, electric power, coal, pharmaceutical, food and other industries. At present, there are two common methods of dry powder dosing; one is wet dosing, that is, the dry powder is configured into a slurry with a certain concentration, and is added to the point of use by a metering pump; the other is dry dosing, that is, the dry powder is The dosing equipment discharges the material to the water ejector, and the water ejector dissolves and transports the dry powder to the place of use. [0003] Both of these process methods require the use of dosing systems for quantitati...
