Abstract

The utility model belongs to the technical field of ore pulp sampling and detection, particularly relates to a flotation concentrate sampler. The flotation concentrate sampler consists of a guardrail ring and a spherical screen, wherein the guardrail ring is provided with an operation handle. A clamping device consists of a hanging ring which is fixedly connected with the upper part of the spherical screen, a bolt that is fixedly connected with the bottom of the guardrail ring, a long strip-shaped pressure plate which is sheathed on the bolt, and a fastening nut that is in threaded connection with the bolt, wherein the long strip-shaped pressure plate leans against and is connected with the hanging ring. The hanging ring is provided with a U-shaped through hole; the height of the U-shaped through hole is greater than the length of the long strip-shaped pressure plate by 2-5mm; and the width of the U-shaped through hole is smaller than the length of the long strip-shaped pressure plate by 8-15mm. When concentrate samples are poured out from the flotation concentrate sampler, granule residual is little, the correctness of concentrate sample granularity is improved and the on-site production can be instructed rapidly in time.

Description

Flotation concentrate sampler

technical field

The utility model belongs to the technical field of pulp sampling and detection, in particular to a flotation concentrate sampler.

Background technique

In mining, among the quality factors of concentrate, the particle size of flotation concentrate is particularly important. Under normal circumstances, workers often use traditional sample spoons to intercept the concentrate, and then observe whether the particle size of the flotation concentrate is normal by naked eyes and hands. However, due to the large flow rate, the flow rate of the slurry is slow and unstable, and the particles in the slurry are easy to flow away when the slurry is clarified. And when pouring the ore slurry, because the inner wall of the sample spoon is rusty and uneven, many particles hang on the inner wall of the sample spoon. It is difficult to select the pulp in this way to reflect the actual situation.

If you want to reflect the concentration and particle size of the ore sample more accurately, the ore sample needs to be dried for a long time before you can measure the particle size of the ore sample. This takes a long time, and the timeliness of guiding the scene is poor.

Contents of the invention

The purpose of the utility model is to provide a flotation concentrate sampler, which detects the particle size of the concentrate pulp, and responds to the change of the concentrate index in time, so as to provide a reliable basis for workers to control the flotation equipment.

The purpose of this utility model is achieved through the following technical solutions:

The flotation concentrate sampler of the utility model is characterized in that it is composed of a guardrail ring, a spherical screen mesh that abuts against the bottom of the guardrail ring through a group of evenly distributed clamping devices, and the guardrail ring is provided with There is an operating handle, and the clamping device is composed of a hanging ring fixedly connected to the upper part of the spherical screen, a bolt fixedly connected to the bottom of the guardrail ring, and a strip-shaped pressing plate set on the bolt, It is composed of fastening nuts threadedly connected with the bolts, and the strip-shaped pressing plate abuts against the hanging ring.

The hanging ring is provided with a U-shaped through hole, and the height of the U-shaped through hole is 2-5mm larger than the length of the strip-shaped pressing plate, and the width of the U-shaped through-hole is wider than the length of the strip-shaped pressing plate. The length is 8-15mm smaller.

Advantage of the utility model:

When the pulp passes through the screen, most of the water flows away through the screen, which can reduce the impact of the pulp on the sampler-sample spoon, and cooperate with the correct sampling method to keep the particles in the mineral on the surface of the screen. Since the sample spoon adopts a spherical screen structure, when the ore sample is poured out, there are few particles remaining, which improves the accuracy of the particle size of the ore sample;

Experienced on-site operators do not need to pour out the ore samples, and can directly judge the particle size in the sampling sieve to guide the operation. It can guide on-site production in time and quickly. the

Detailed ways

The specific embodiment of the utility model is described below in conjunction with accompanying drawing.

As shown in Figures 1, 2, and 3: the flotation concentrate sampler of the present invention is characterized in that the guardrail circle 1 is connected to the bottom of the guardrail circle 1 through a group of evenly distributed clamping devices 2 The spherical screen 3 is composed of an operating handle 4 on the guardrail ring 1, and the clamping device 2 is composed of a hanging ring 2-1 fixedly connected to the upper part of the spherical screen 3, and the Bolt 2-4 fixedly connected to the bottom of the guardrail ring 1, a strip-shaped pressure plate 2-2 set on the bolt 2-4, and a fastening nut 2-3 threaded with the bolt 2-4 are formed. The elongated pressing plate 2-2 abuts against the hanging ring 2-1.

The hanging ring 2-1 is provided with a U-shaped through hole, and the height of the U-shaped through hole is 2-5 mm larger than the length of the elongated pressing plate 2-2. The U-shaped through hole is The width is 8-15mm smaller than the length of the strip platen.

The utility model is a detachable structure up and down. In the overall structure, the strip-shaped pressing plate 2-2 is placed horizontally, that is, the strip-shaped pressing plate 2-2 is pressed on the surface of the hanging ring 2-1 across the U-shaped through hole, and the guardrail Ring 1 and spherical screen 3 are fixedly connected together; when splitting is required, loosen the fastening nut so that the strip-shaped pressing plate 2-2 is vertically placed, and the strip-shaped pressing plate 2-2 is connected from the hanging ring 2-1 Deviate from in the U-shaped through-hole, guardrail ring 1 and spherical screen cloth 3 separate immediately.
