Embodiment 1

[0025] Such as figure 1 As shown, the invention conveys ingredients for ultrafine powder, including a motor 1, a housing 4 and a screw conveyor, and the screw conveyor includes a left screw conveyor 5 and a right screw conveyor 6, and a left screw conveyor 5 and a right screw conveyor 6 are fixed in the casing 4 in parallel up and down, and their transmission directions are opposite. When the left screw conveyor 5 is running, it transmits powder to the left, and when the right screw conveyor 6 is running, it transmits powder to the right. The left screw conveyor 5 and the right screw A separation plate 7 is arranged between the conveying devices 6, the two ends of the separating plate 7 and the housing 4 form a cavity A8 and a cavity B9, the housing 4 on the upper part of the left screw conveying device 5 is provided with a material inlet 2, and the right screw conveying device 6 The shell 4 at the bottom is provided with a discharge port 3, the upper part of the feed port 2 i...

Embodiment 2

[0029] The difference from Embodiment 1 is that the angle formed by the baffle plate A and the baffle plate B and the housing 4 is 30 degrees, and the angle between the left screw conveying device 5 and the right screw conveying device screw 6 and the horizontal plane is 5 degrees when they are installed. , the other works in the same way.

[0030] The experimental situation of embodiment 2 is as follows:

[0031] Four inlets 2 and ten outlets 3 are adopted. The left screw conveying device 5 and the right screw conveying device 6 have a nominal diameter (mm) of DN150, a conveying length of 26 meters, and an ultrafine powder particle size of 0.8 μm. The operating environment temperature is 30°C, and the maximum rotation speed is 100 (rpm). After testing, the transmission volume of ultrafine powder is 12 m 3 / h.

Embodiment 3

[0033] The difference from Example 1 is that the angle formed by the baffle plate A and the baffle plate B and the housing 4 is 60 degrees, and the angle between the left screw conveying device 5 and the right screw conveying device 6 and the horizontal plane is 20 degrees when they are installed in a screw. , the other works in the same way.

[0034] Four inlets 2 and ten outlets 3 are used, the left screw conveying device 5 and the right screw conveying device 6 have a nominal diameter (mm) of DN200, a conveying length of 40 meters, and an ultrafine powder particle size of 4 μm. The ambient temperature is 25°C, and the maximum number of rotations is 100 (rpm). After testing, the amount of ultra-fine powder conveyed is 15 m 3 / h.

Abstract

The invention discloses a conveying and distributing device for ultrafine powder, which comprises a motor (1), feeding ports (2), discharging ports (3), a shell (4) and a spiral conveying device. The conveying and distributing device is characterized in that the spiral conveying device comprises a left spiral conveying device (5) and a right spiral conveying device (6), of which the conveying directions are opposite; the left spiral conveying device (5) and the right spiral conveying device (6) are fixed in the shell (4) in a vertical parallel form, wherein a separating plate (7) is arranged between the left spiral conveying device (5) and the right spiral conveying device (6); and a cavity A (8) and a cavity B (9) are formed between one of the separating plate (7) and the shell (4) and the other end of the separating plate (7) and the shell (4). The conveying and distributing device provided by the invention is provided with a plurality of feeding ports and discharging ports, so that the multi-point feeding and multi-point discharging conveying and distributing are realized. The conveying and distributing device provided by the invention has the characteristics of high conveying capacity, low energy consumption, small volume and low manufacturing cost.

Description

technical field [0001] The invention relates to a conveying and batching equipment, in particular to an ultrafine powder conveying and batching device. Background technique [0002] In the production process of ultrafine powder, according to the needs, the ultrafine powder powder of various specifications (particle sizes) on several production lines is switched and transported to different silos for storage. Therefore, multi-point feeding and multi-point feeding are required. Point out the conveying and batching device to solve the problem. [0003] At present, the conveying and batching devices capable of multi-point feeding and multi-point discharging of ultrafine powder mainly include pneumatic conveying and mechanical conveying and dosing devices, that is, pipe chain conveying and dosing devices. These two kinds of conveying and batching devices have certain disadvantages: the pneumatic conveying and batching device is more flexible, but the auxiliary equipment such as ...
