Problems solved by technology

[0006] Technical problem 1: Silica sand is widely used. In different application occasions, the requirements for the particle size (mesh number, particle size) of the sand are also different, and the requirements for the particle size concentration ratio of each brand of silica sand are also different, especially in the scale In the process of mass production, the demand for quantity may be greater than the requirement for precision
[0007] Technical problem 2: In the process of separating sand by hydraulic classification, firstly, the sand in the water production line is divided into three categories, namely floating layer, suspended layer and sinking bottom layer, which occupy the upper, middle and lower layers of the sorting container
The disadvantage is: hydraulic classification is based on the characteristics of water flow to achieve the sepa

Embodiment 1

[0100] A petroleum fracturing proppant production line includes a feeding system, a pretreatment system, a primary sorting system, and a secondary sorting system. The feeding system is used to continuously supply mortar raw materials from The mortar raw materials supplied by the feeding system include but are not limited to dehydration, concentration, impurity removal, scrubbing, and lifting operations. The primary sorting system is used to sort the coarse products of the mortar processed by the pre-treatment system. The secondary sorting system It is used for fine product sorting of mortar after being sorted by a sorting system; the coarse product is a silica sand product with a mesh number in the range of 40-100, and the fine product is a silica sand product with a mesh number in the range of 70-200 Silica sand products within. The mortar refers to a mixture with water and sand as the main components, which may contain a small amount of impurities such as mud, dirt, and garb...

Embodiment 2

[0144] Such as figure 2 As shown, on the basis of the above-mentioned embodiments, the primary sorting system described in this embodiment is provided with two sets of parallel primary classifiers, and there are two sub-machines, two sub-machines, three sub-machines, and four sub-machines;

[0145] There is a first distributor between the two sub-machines and the second impurity screen. The first distributor has a three-way structure, and a mixing chamber is provided at the intersection of the three-way. The mixing chamber is used for mixing evenly by the first The impurity sieve enters the mortar of two one-extension machines;

[0146] The outlets of the two sub-units share the first product pool, the overflow outlets share the second product pool, and the outlets of the two four-unit machines share the second product pool.

[0147] The secondary sorting system is provided with two sets of parallel secondary classifiers, and the five-point machine and the six-point machine ...

Embodiment 3

[0153] On the basis of the above-mentioned embodiments, the primary classifier described in this embodiment is shaped as a drum, and the bottom of the drum is provided with an inverted conical shell 1, such as Figure 4 As shown, a plurality of water inlet holes 101 are annularly distributed on the side of the conical shell 1, so that the annularly distributed water inlet holes 101 have multiple layers, and the upper edge of the conical shell 1 is welded together with the inner surface of the drum. The lower edge is welded to the bottom surface of the drum, and the drum is divided into upper and lower cavities by the conical shell 1, the upper cavity is the settlement space 2, the lower cavity is the water inlet space 3, and the side of the water inlet space 3 is A water inlet pipe 301 is provided on the wall; a discharge port 302 is provided below the conical shell 1; the discharge port 302 is connected with the bottom surface of the drum, and a valve is provided in the discha...

Abstract

The invention relates to the technical field of wet solid-solid separation equipment and methods, and particularly relates to a petroleum fracturing propping agent production line and a petroleum fracturing propping agent production process. The production line comprises a feeding system, a pretreatment system, a primary sorting system and a secondary sorting system; the feeding system is used forcontinuously supplying mortar raw material to a sorting device from a mortar source, the pretreatment system is used for carrying out operations including but not limited to dehydration, concentration, impurity removal, swaging and lifting on the mortar raw material supplied by the feeding system, the primary sorting system is used for carrying out coarse product sorting on the mortar treated bythe pretreatment system, the secondary sorting system is used for carrying out fine product sorting on the mortar sorted by the primary sorting system. The production line and the production process have the beneficial effects that the water flow direction is improved according to different requirements, independent hydrocyclone separation or settling separation is realized, and a separation modeof combining the hydrocyclone separation and the settling separation can also be realized, and the machine has multiple functions, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of wet solid-solid separation equipment and methods, in particular to a production line and production process of a proppant for oil fracturing. Background technique [0002] In recent years, silica sand (quartz sand) has been widely used in glass, foundry and other industrial sectors, but before application, it generally needs to be classified or deslimed. Quartz sand is an important industrial mineral raw material, widely used in glass, casting, metallurgy, chemical industry, abrasives and other industrial fields. The production of quartz sand is mostly obtained by crushing and grading quartzite ore. Of course, in areas rich in natural sand resources, the sand source can be directly mined. The production process of quartz sand has two kinds of wet production and dry production. Quartz sand as glass raw material is mainly produced by wet process. Wet process production has the following advantages: high ...
