Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mechanism sand experimental auxiliary equipment, especially to a mechanism sand stone powder content test pretreatment device. BACKGROUND

[0002] The stone powder content can be used to represent the amount of powder produced in the production process of the mechanism sand. At present, the main steps of the mechanism sand stone powder content test in the laboratory are as follows: 500g of the dried sample is taken and placed in a container, water is injected to about 150mm above the sand surface, and after being fully mixed, it is soaked for 2h, then it is washed by hand in the water, the turbid liquid is poured into 1.25mm and 0.075mm square hole sleeve screen, and the particles smaller than 0.075mm are filtered out. Wash until the water is clear. The residual particles of the two screens and the washed sample in the washing container are poured into a porcelain plate and placed in a drying oven at (105±5)℃ to dry to constant weight, and the mass is weighed and accurate to 0.1g. The process needs to be repeatedly rubbed and washed by hand, which is complicated and time-consuming, and the test efficiency is low.

[0003] A method for quickly detecting the stone powder content of mechanism sand is disclosed in the publication No. CN118730834A on October 01, 2024, which belongs to the technical field of test detection. The method can solve the problem of long detection time of the existing mechanism sand stone powder content detection method. The test method is to inject a certain amount of water into the mechanism sand and shake it to make the stone powder on the surface of the sand float in the water. When it is stationary, the mechanism sand will first sink to the bottom of the graduated cylinder, and the stone powder in the mechanism sand will sink to the upper part of the sand, forming a visible boundary layer. The volume of the mechanism sand layer and the volume of the stone powder layer are recorded within a specified time. The ratio of the two volumes has a certain relationship with the stone powder content of the mechanism sand. Then, by multiplying the correction coefficient obtained by the standard method and the determination method of the invention, the stone powder content of the mechanism sand can be obtained. The above-mentioned method cannot stably remove the stone powder on the surface of the mechanism sand during work, and the stone powder content on the surface of the mechanism sand after the mechanism sand is removed is high, which leads to inaccurate results of the mechanism sand stone powder content detection and poor practicability.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] like Figures 1-2 As shown, the pretreatment device for testing the content of manufactured sand and gravel includes a box 1 and a cover plate 2 set on the box 1. The box 1 is equipped with a screen 11 for placing manufactured sand. The cover plate 2 is equipped with a water inlet pipe 3 and a stirring component for stirring the manufactured sand. Specifically, the water inlet pipe 3 is connected to a water tank. The water tank is equipped with a water pump connected to the water inlet pipe 3. The water pump works to deliver water to the box 1.

[0025] When in use, the manufactured sand is placed in the screen 11, and the water inlet pipe 3 on the cover plate 2 works to drain water into the box 1. The stirring component works to stir the manufactured sand in the screen 11 in the water, thereby cleaning the stone powder on the surface of the manufactured sand. This makes the stone powder content test results of the manufactured sand more accurate and more practical. The cleaned manufactured sand is taken out from the screen 11 for testing. The cleaning of the manufactured sand does not require manual stirring.

[0026] The stirring assembly comprises a motor 8 arranged on the cover plate 2, a rotating shaft 9 arranged at a power output end of the motor 8, the rotating shaft 9 penetrating through the cover plate 2 and extending into the box body 1, and a stirring blade 10 arranged in the box body 1 and connected with the rotating shaft 9.

Specifically, the ultrasonic vibrator 7 comprises an ultrasonic generator and a transducer. The ultrasonic generator generates high-frequency electric signals, and the signals are transmitted to the transducer through a cable. The transducer converts the high-frequency electric signals into mechanical vibrations, and transmits the vibrations to the entire box body and the water in the box body. The micro bubbles in the water produce violent vibration and burst phenomenon (i.e. “sonic cavitation effect”) under the action of the sound field, so as to generate strong impact force to collapse and clean the stone powder on the surface of the manufactured sand.
