The embodiment relates to a thick liquids unloader, and on the whole constitution, this thick liquids unloader includes a plurality of thick liquids unloading subassemblies of interval arrangement from top to bottom. The slurry blanking assembly comprises two parallel arranged blanking rollers driven to rotate, and a first scraping unit 7 arranged corresponding to at least one of the blanking rollers.

And a discharging channel is formed between the two discharging rollers, the width of each discharging channel is gradually reduced along the direction from top to bottom, and slurry can flow through each discharging channel from top to bottom. The first scraping unit 7 has a first scraping portion for scraping the slurry adhered to the discharging roller, and the scraped slurry can flow into the discharging passage below the first scraping portion.

Based on the above general description, an exemplary structure of the slurry blanking device described in the present embodiment is shown in fig. 1. Two slurry blanking assemblies which are arranged up and down are indicated in the slurry blanking device so as to carry out secondary dispersion blanking on premixed slurry. Of course, in specific implementation, the number of the slurry blanking assemblies can be increased according to the use requirement.

For the convenience of the following description, in the present embodiment, the slurry blanking assembly disposed above is referred to as a first slurry blanking assembly, the slurry blanking assembly disposed below is referred to as a second slurry blanking assembly, and the blanking channels in the first slurry blanking assembly and the second slurry blanking assembly are referred to as a first blanking channel 100 and a second blanking channel, respectively.

The slurry blanking device in the embodiment further comprises a discharge pipe 12 and a material receiving box 11 which are arranged at intervals up and down, the premixed slurry flows out through a discharge hole of the discharge pipe 12, and the material receiving box 11 is used for receiving the dispersed slurry. The first slurry blanking component and the second slurry blanking component are arranged between the discharge port of the discharge pipe 12 and the material receiving box 11 at intervals. In order to improve the effect of the slurry flowing into the first feeding channel 100 from the discharge port, the discharge port in this embodiment extends along the length direction of the first feeding channel 100.

To illustrate the specific structure of the slurry blanking assembly, the first slurry blanking assembly is described below, with reference to fig. 1 and 2, in which two blanking rollers are rotatably disposed on the frame 3. For the sake of convenience of distinction, the two blanking rollers in this embodiment are referred to as a first blanking roller 1 and a second blanking roller 2, respectively. The first blanking roller 1 is located at the upper right of the second blanking roller 2, the discharge pipe 12 is located above the second blanking roller 2, and the premixed slurry is conveyed into the first blanking channel 100 through a discharge port on the discharge pipe.

The first blanking roller 1 includes a first roller body 102 and first roller shafts 101 respectively provided at both ends of the first roller body 102. The second blanking roller 2 includes a second roller body 202 and second rollers 201 respectively provided at both ends of the second roller body 202. The first blanking roller 1 and the second blanking roller 2 are respectively arranged on the frame 3 through a first roller shaft 101 and a second roller shaft 201 in a rotating way.

In addition, in the embodiment, the rotation speed of the first blanking roller 1 is greater than that of the second blanking roller 2, so that more slurry which cannot pass through the first blanking channel 100 can be adhered during rotation. For example, the rotation speed of the first blanking roller 1 is 3 to 5 times of the rotation speed of the second blanking roller 2, and in specific implementation, the rotation speed between the two can be adjusted according to the use requirement. The rotating speed of the first blanking roller 1 is greater than that of the second blanking roller 2, so that the blanking effect of the slurry can be facilitated. And in order to further improve the adhesion effect of the first blanking roller 1 to the slurry, the cross-sectional area of the first blanking roller 1 is larger than that of the second blanking roller 2.

In order to prevent the slurry from overflowing the first feeding passage 100, in the present embodiment, as shown in fig. 3, a radially outward protrusion 1021 is provided on the circumferential direction of the first roller 102, and a radially inward concave groove 2021 is provided on the circumferential direction of the second roller 202. The protrusion 1021 is disposed in the groove 2021, and a first blanking channel 100 is formed between the protrusion 1021 and the groove 2021.

The second blanking roller 2 can be moved away from or close to the first blanking roller 1 in a vertical direction so that the width of the first blanking channel 100 therebetween is adjustable. For example, the width of the first blanking channel 100 can be adjusted to any value from 10um to 2mm, for example, the width is 10um, 50um, 100um, 150um, 200um, etc. In specific implementation, the specific value of the width can be selected according to the use requirement.

The width of the first blanking channel 100 and the width of the second blanking channel can be determined according to the components of the slurry and the requirement of dispersion degree. The position of the discharge opening of the corresponding discharge pipe 12 and the discharge speed of the slurry can be adjusted according to the use requirements, as long as the use requirements are met.
