Problems solved by technology

[0003] The traditional ball-milling mineral slurry (such as coal-water slurry) crushing technology has high power consumption, mainly due to high internal friction; at the same time, the controllability of the crushing particle size in mineral slurry (such as coal-water slurry) is poor, and the loss of steel balls is large; in addition , the bulk of the overall device

Embodiment 1

[0025] Embodiment 1: a kind of thinning device of mineral slurry, such as figure 1 As shown, it includes a housing 1 with a material inlet 7 and a material outlet 8. Two deflector plates 20, 21 are arranged in the housing 1. The edges of the guide discs 20, 21 are arc-shaped, and the There are valve bodies 30, 31 with high wear resistance on the top of the surface, and the outer surfaces of the valve bodies 30, 31 form frictional impact surfaces; the deflector plates 20, 21 and the surfaces of the valve bodies 30, 31 arranged oppositely form mineral slurry The jet cavity 4; a guide plate 21 and its valve body 31 have a through hole, the through hole forms a slurry channel 5; the area where the slurry channel 5 communicates with the jet cavity 4 forms an impact cavity 6.

[0026] The first valve body 30 on the first deflector plate 20 is connected to the driving mechanism, and the first valve body 31 on the second deflector plate 21 is fixed to the second deflector plate 21 . ...

Embodiment 2

[0031] Embodiment 2: a kind of thinning device of mineral slurry, such as figure 2 and image 3 As shown, a guide plate 21 and its valve body 31 are provided with a plurality of through holes, and the plurality of through holes form a plurality of slurry channels 5 . All the other structures are the same as in Embodiment 1

Embodiment 3

[0032] Embodiment 3: a kind of thinning device of mineral slurry, such as figure 1 , figure 2 , Figure 4 , Figure 6 , Figure 8 and Figure 10 As shown, the valve body on the guide plate and the main body of the corresponding guide plate are separate structures.

Abstract

The invention relates to a device provided with a diversion plate and an adjustable valve body, which is suitable for matching with complete equipment for processing mineral slurry. It includes a housing with a material inlet and a material outlet. There are at least two deflectors in the housing. The surface forms a frictional impact surface; the surface of the guide plate and its valve body arranged oppositely forms a jet cavity for mineral slurry; at least one guide plate and its valve body are provided with a through hole, and the through hole forms a slurry channel; The area where the feed channel communicates with the jet cavity forms an impact cavity. The beneficial effect of the present invention is that: the deflector plate can guide the path where the mineral slurry enters, and the valve body provided on it can not only change the volume of the impact chamber, but also provide space for material fragments. By adjusting the distance between the corresponding valve bodies through the driving mechanism, the jet pressure entering the cavity can be changed, and the crushing particle size can be effectively controlled.

Description

【Technical field】 [0001] The invention relates to a refining device for mineral slurry, in particular to a device equipped with a deflector plate and an adjustable valve body, which is suitable for matching with complete equipment for processing mineral slurry. 【Background technique】 [0002] The large-scale production of mineral slurry (such as coal water slurry) has so far mostly been carried out by using the wet ball milling technology of the ball vibrating rod mill. The traditional technology is to use a jaw crusher to crush the raw ore (such as coal) or selected ore (such as coal) to 20-30mm particles, remove the iron in the ore (such as coal) through the iron remover, and then pass through the hammer The crusher crushes the particles below 3-5 mm, adds water and additives in proportion to form mineral primary slurry, and enters the ball mill, and obtains mineral slurry (such as coal water slurry) under the action of ball milling in the ball mill. After filtering, a st...
