Description

Automatic collect rubbing crusher of incomplete appearance

Technical Field

The invention relates to a pulverizer for automatically collecting residual samples.

Background

The crushing operation of the sample is a key step of sample preparation, particularly, in the last step of sample crushing, the loss rate of the sample has a strict requirement, the existing crusher often has the problem that the sample is retained on a sieve sheet, and at the moment, a cover needs to be opened manually or the sample needs to be sucked away through negative pressure so as to prevent the pollution to the next sampling sample. But uncapping and cleaning not only increases the workload of workers and reduces the production efficiency, but also can cause the loss rate of samples to exceed the standard.

Disclosure of Invention

The invention aims to solve the defects of the prior art and provides a pulverizer for automatically collecting residual samples.

A pulverizer for automatically collecting residual samples comprises a pulverizer box body, wherein a pulverizing cavity is arranged above the pulverizer box body, a pulverizing disc is arranged inside the pulverizing cavity, an arc-shaped screen sheet is arranged below the pulverizing cavity, first micropores and second micropores are arranged on the surface of the screen sheet, and the diameter of the second micropores is larger than that of the first micropores; the side of crushing chamber is equipped with the cylinder, the tip of the cylinder push rod of cylinder even has movable layer board, the rear end of movable layer board is articulated mutually with the cylinder push rod, and the preceding terminal surface of movable layer board is the arcwall face that matches with the sieve piece, and when the cylinder push rod stretched out forward, the preceding terminal surface butt of movable layer board was in second micropore department.

Preferably, a detachable sample bottle is arranged inside the crusher box.

Preferably, the inside of the crusher box is provided with a sample bottle on a lifting tray at the tail end of a cylinder mandril.

Preferably, the end part of the crushing disc is connected with a motor through a main shaft assembly and a coupling.

Preferably, the feed inlet of the crushing cavity is positioned on a movable cover with the front surface of the crushing cavity capable of being opened, and the feed inlet extends upwards in an L shape.

Preferably, the pore size of the first micropores is 0.2 to 0.4 mm.

Preferably, the diameter of the second micro-holes is 2-8 mm.

Preferably, the distance between the first micropore and the second micropore is 20-40 mm.

Has the advantages that:

this device can be in the kibbling last link of sample through setting up the second micropore with first micropore matched with, and the loss rate of the sample that significantly reduces.

After crushing, the cylinder retreats, and the movable supporting plate leaves the sieve piece, and because the aperture of the second micropore is far greater than the aperture of the first micropore, the sample remained on the sieve piece falls into the sample bottle through the second micropore on the left side of the sieve piece in the process that the crushing disc continuously rotates.

Detailed Description

For the purpose of enhancing the understanding of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, which are only used for explaining the present invention and are not to be construed as limiting the scope of the present invention.

As shown in fig. 1-3, an automatic collect rubbing crusher of incomplete appearance, including rubbing crusher box 13, rubbing crusher box 13's top is equipped with crushing chamber 4, the inside in crushing chamber 4 is equipped with crushing dish 9, and the below in crushing chamber 4 is equipped with and is curved sieve piece 10, the surface of sieve piece 10 is equipped with first micropore and second micropore, and first micropore's aperture is 0.2-0.4mm, and the diameter of second micropore is 5mm, and the distance between first micropore and second micropore is 30 mm.

The diameter of the second micropore is larger than that of the first micropore; the side of crushing chamber 4 is equipped with cylinder 7, the tip of the cylinder push rod of cylinder 7 even has movable layer board, the rear end of movable layer board 8 is articulated mutually with the cylinder push rod, and the preceding terminal surface of movable layer board is the arcwall face that matches with the sieve piece, and when the cylinder push rod stretched out forward, the preceding terminal surface butt of movable layer board 8 was in second micropore department.

The crusher box 13 is internally provided with a sample bottle 12 on a lifting tray at the tail end of a cylinder mandril.

The end part of the crushing disc 9 is connected with the motor 1 through the main shaft assembly 3 and the coupling 2.

The feed inlet of the crushing cavity is positioned on the movable cover 5 of the crushing cavity, and the feed inlet extends upwards in an L shape.

When the air cylinder 7 is ventilated, the push rod of the air cylinder extends out slowly, and when the push rod reaches the end, the movable supporting plate 8 automatically aligns around the rotating shaft to be matched with the sieve sheet 10, so that the second micropores are shielded. After the crushing is finished, the cylinder push rod slowly withdraws from, and the movable supporting plate 8 rotates a certain angle around the rotating shaft, so that the residual sample falls into the sample bottle 12 through the second micropores.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
