Abstract

The utility model discloses a long-distance conveying device for white carbon black products. The long-distance conveying device comprises a Roots blower (1), a discharge device (2), a butterfly valve (3), a feeding bin (4), a powder return pipe (5), a long-distance conveying pipe (6), a large arc elbow (7), a material collecting bin (8) and a cloth bag collector (9). The powder return pipe (5) is arranged between the discharge device (2) and the feeding bin (4), a mounting clearance a between a discharge device blade (2-10) and a casing (2-3) is 0.10-0.20mm, and the bending external radius R of the connecting elbow (7) on the conveying pipe is no smaller than 10DN. The diameter of the conveying pipe and fan motor power can be reduced, and one-time investment and operating costs of the conveying device are remarkably reduced.

Description

The remote feedway of white carbon product

Technical field

The utility model relates to material transfer equipment, is specifically related to the remote feedway of white carbon product.

Background technology

Precipitated silica is a kind of widely used fine chemical product, is mainly used in fields such as rubber, silaatic, plastics, coating, printing ink, agricultural chemicals, papermaking, food, medicine, feed.Because the white carbon finished product is attritive powder, light specific gravity is about 0.2-0.3, therefore collects in the course of conveying at the white carbon finished product, what usually adopt is that negative pressure device is carried, so have that the pipeline diameter of negative pressure device is big, blower motor power is big, plant investment and the high defective of over-the-road expense.

Summary of the invention

The purpose of this utility model provides a kind of remote feedway of white carbon product little, that over-the-road expense is low of investing.

For realizing above purpose, the remote feedway of the utility model white carbon product comprises Roots blower, Blowing stopper, butterfly valve, feed storehouse, returns powder flexible pipe, remote delivery pipe, large radius elbow, rewinding storehouse and cloth bag storage, the powder retrieving pipe road is located between Blowing stopper and the feed storehouse, the assemblage gap precision of Blowing stopper intra vane and housing is a=0.10-0.20mm, the crooked outside radius R 〉=10DN of the connecting bend on the pipeline.

The remote feedway of said structure white carbon product has carried out particular design according to the products characteristics of white carbon to discharging opening Blowing stopper structure, the assemblage gap precision of Blowing stopper intra vane and housing becomes 0.10-0.20mm more than original 2mm, can effectively control back the powder amount increases, and by setting up a powder retrieving pipe road, the fine powder white carbon that utilizes the negative pressure of feed Cang Ding that Blowing stopper inside is failed to transfer out in time returns in the storehouse, has avoided this fraction fine powder to influence feed storehouse blanking amount; Because white carbon product pellet hardness height, for reducing the white carbon powder to the wearing and tearing of pipeline, the connecting bend radius of curvature R 〉=10DN(transfer line external diameter on the pipeline is adopted in design).

Adopt the remote feedway of the utility model white carbon product, can reduce feed line diameters and blower motor power, can significantly reduce feedway one-time investment and over-the-road expense.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 ~ shown in Figure 4, the remote feedway of the utility model white carbon product comprises Roots blower 1, Blowing stopper 2, butterfly valve 3, feed storehouse 4, returns powder flexible pipe 5, remote delivery pipe 6, large radius elbow 7, rewinding storehouse 8 and cloth bag storage 9, return powder flexible pipe 5 and be connected to feed storehouse 4 from returning powder mouth 2-7, Blowing stopper blade 2-10 and housing 2-3 assemblage gap a=0.10-0.20mm, the connecting bend 7 radius of curvature R 〉=10DN(on the transfer line refers to the transfer line external diameter).

The power of motor of Roots blower 1 is 18.5kW, and Blowing stopper 2 powers of motor are 1.5kW, and pipe diameter is DN150, and fed distance is 300m.By nearly 6 months actual test, this feedway operation is normal, former employing negative pressure transportation device, and equipment drops into needs 600,000 yuan, and year needs 350,000 yuan of over-the-road expenses; After adopting new equipment, equipment drops into needs 200,000 yuan, and year needs 150,000 yuan of over-the-road expenses.

Claims

1. remote feedway of white carbon product, comprise Roots blower (1), Blowing stopper (2), butterfly valve (3), feed storehouse (4), remote delivery pipe (6), large radius elbow (7), rewinding storehouse (8) and cloth bag storage (9), it is characterized in that: between Blowing stopper (2) and feed storehouse (4), set up a powder retrieving pipe road (5), Blowing stopper blade (2-10) and housing (2-3) assemblage gap a=0.10-0.20mm, the crooked outside radius R 〉=10DN of the connecting bend on the transfer line (7).
