Description

Technical Field

[0001] This utility model relates to the production of quartz sand deep processing washing and beneficiation operations, specifically to an automated testing device for the washing and beneficiation production process. Background Technology

[0002] In the quartz sand washing and beneficiation process, a certain mass of quartz sand (the material to be washed) is placed in a production tank (fluidized bed for washing and beneficiation). A reagent (washing medium) prepared in a specific ratio flows repeatedly within the production tank, ensuring thorough contact between impurities on the quartz sand surface and the reagent. The temperature within the production tank is maintained to preserve the reagent's activity. The continuous relative flow between the quartz sand and the reagent allows impurities generated during the washing reaction to be rapidly removed. The appropriate reagent composition ratio and ambient temperature are crucial technical means to accelerate the reaction process, reduce washing time, improve processing efficiency, and decrease production costs.

[0003] Currently, during the experiment, the prepared quartz sand and reagents are placed into sample bottles according to the production ratio. The sample bottles are then placed in a water bath at a set temperature. Due to the long testing time (8-48 hours), to prevent the washed quartz sand and impurities from caking, personnel are arranged to shake the sample bottles periodically (once per hour) to simulate the production process and improve the test results. Currently, the test is generally used as a preliminary judgment on whether newly supplied quartz sand can be used; it is a rough test method.

[0004] In the washing and beneficiation process, how to select the appropriate reagent composition and ratio, maintain the reaction temperature and time, reduce environmental protection costs, and lower overall production costs is a major issue requiring continuous improvement. To address this, the applicant proposes an automated testing device to achieve continuous relative movement between quartz sand and reagents during the experiment, thereby reproducing the washing and beneficiation process and eliminating data deviations caused by manual operation. Utility Model Content

[0005] The purpose of this invention is to provide an automated testing device for quartz sand washing experiments. This device eliminates manual operation while ensuring the timed and quantitative flipping of the sample tray. By effectively controlling the up-and-down swinging motion of the sample tray, it achieves full contact between the quartz sand and the reagent in the sample bottle and allows the impurities from the washing reaction to be quickly removed. This accurately reproduces the washing process and provides more accurate data support for production guidance.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An automated test apparatus for quartz sand washing and beneficiation includes a water tank and a heater installed inside the water tank for heating the water in the tank. It also includes a sample tray, a support, a sample bottle, and a swing drive mechanism. The support is fixedly installed at the bottom of the water tank, the sample tray is located above the support, and the sample bottle is placed on the sample tray. The left end or near the left end of the sample tray is rotatably connected to the top of the support, and the swing drive mechanism is connected to the right end or near the right end of the sample tray. The swing drive mechanism causes the sample tray to swing up and down around the top of the support, causing the sample bottle inside the sample tray to roll left and right.

[0007] Furthermore, the swing drive mechanism includes a motor located outside the water tank and above the sample tray. The output shaft of the motor is connected to a crank. The other end of the crank is rotatably connected to the upper end of the connector, and the lower end of the connector is rotatably connected to the right end or near the right end of the sample tray.

[0008] Furthermore, the connector is a flexible connection structure.

[0009] Furthermore, the connecting member is a rigid linkage structure.

[0010] Furthermore, it also includes a control device, which is connected to the motor control.

[0011] Furthermore, the control device includes a timer to periodically issue commands to the motor.

[0012] Furthermore, it also includes a temperature measuring element installed inside the water tank. The temperature measuring element is used to measure the water temperature inside the water tank and send the detected signal to the control device, which then sends a command to the heater.

[0013] Furthermore, the sample vial is cylindrical.

[0014] Furthermore, the sample bottle is provided in two or more parts.

[0015] Furthermore, the water level in the tank is higher than the highest point of movement of the sample bottle.

[0016] The beneficial effects of this utility model are: 1. The experimental device of this utility model reproduces the quartz sand washing and beneficiation production process. The combination of water tank and heater can maintain the temperature to simulate the production environment. The sample bottle simulates a fluidized bed. The quartz sand and reagents in the bottle are configured according to the experimental ratio requirements. The swing drive mechanism controls the sample tray to swing up and down, so that the sample bottle rolls at time and in quantity, which enables the reagents and sand samples to be effectively mixed and soaked, improving the contact efficiency between the quartz sand sample and the reagent medium, and achieving the purpose of high-efficiency purification and cost saving.

[0017] During the rolling of the sample bottle, the quartz sand inside the bottle sinks due to gravity and moves relative to the reagent, causing the impurities generated by the reaction to flow away. At the same time, this avoids the quartz sand and impurities from hardening during long-term testing, thus reducing solidification.

[0018] 2. The swing drive mechanism of this utility model adopts a crank-connecting rod mechanism. The motor rotates or stops through a timed on / off control device, causing the cylindrical sample bottle placed on the sample tray to rotate and roll, thus achieving timed and quantitative rolling.

[0019] 3. This utility model heats the water in the water tank using a heater. After the temperature measuring element measures the temperature, the feedback control device sends a command to open and close the heater circuit to maintain a constant water temperature.

[0020] 4. This utility model eliminates the need for manual operation during operation, reducing labor intensity and preventing data deviations caused by human inertia.

[0021] 5. For different impurity compositions of incoming quartz sand, this utility model can easily adjust the ratio of reagent components, washing and screening environment temperature, and processing time to conduct multiple batch small-scale tests. The optimal production process can be selected and calculated from the big data of test results, providing important data support for guiding actual production. Attached Figure Description

[0022] Figure 1 This is a schematic diagram of the structure of this utility model.

[0023] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the present invention. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] like Figure 1 As shown, this embodiment provides an automated testing device for quartz sand washing and beneficiation experiments, including a water tank 1, a sample tray 3, a support 4, a sample bottle 5, a heater 6, a control device 7, a temperature measuring element 8, and a swing drive mechanism.

[0026] Water is filled into water tank 1 to the liquid level line 2, which must be higher than the highest movement position of the sample bottle. Heater 6 is installed inside water tank 1 to heat the water. A temperature sensing element 8 is also installed inside water tank 1 to measure the water temperature and send the detected signal to control device 7. Control device 7 then sends commands to the heater 6 circuit to control the water temperature.

[0027] The support 4 is fixedly installed at the bottom of the water tank 1, the sample tray 3 is located above the support 4, and the sample bottle 5 is placed on the sample tray 3. The left end of the sample tray 3 is rotatably connected to the top of the support 4, and the swing drive mechanism is connected to the right end of the sample tray. The swing drive mechanism drives the sample tray 3 to swing up and down around the top of the support 4, causing the sample bottle 5 inside the sample tray 3 to roll left and right, thereby turning over the quartz sand in the sample bottle.

[0028] In this embodiment, the swing drive mechanism includes a motor 9, a crank 10, and a connector 11. The connector 11 can be a rigid connecting rod or a soft rope. The motor 9 is located outside the water tank and above the sample tray 3. The output shaft of the motor 9 is connected to the crank 10. The other end of the crank 10 is rotatably connected to the upper end of the connector 11, and the lower end of the connector 11 is rotatably connected to the right end of the sample tray 3, thereby forming a crank-connecting rod mechanism.

[0029] The specific parameters of the swing drive mechanism are as follows: Motor 9 is a DC motor (10W, 2r / min); crank swing amplitude: ±30mm (up and down); heater: 220V, 1.5Kw.

[0030] The control device 7 includes a timer, which sends commands to the circuit opening and closing of the motor 9 by setting the timer period, controls the intermittent rotation of the motor 9, thereby causing the sample bottle 5 to roll periodically, thus improving the pickling effect.

[0031] In this embodiment, sample bottle 5 is cylindrical to improve the rotation and tumbling effect. The number of sample bottles can be set to two or more to improve testing efficiency.

[0032] This invention's experimental apparatus reproduces the quartz sand washing and beneficiation process. The combination of water tank 1 and heater 6 maintains the temperature to simulate the production environment. Sample bottle 5 simulates a fluidized bed, with quartz sand and reagents mixed according to experimental proportions. Motor 9 rotates, causing sample tray 3 to swing up and down, prompting sample bottle 5 to rotate periodically and quantitatively. This ensures effective mixing and soaking of the reagents and sand sample, improving the contact efficiency between the quartz sand sample and the reagent medium, achieving efficient purification and cost savings. During the rotation of the sample bottle, the quartz sand sinks due to gravity and moves relative to the reagents, causing impurities generated in the reaction to flow away. This also prevents the quartz sand and impurities from caking during long-term experiments, reducing solidification.

[0033] This invention allows for convenient adjustment of reagent composition ratios, washing and screening ambient temperature, and processing time to address different impurity compositions in incoming quartz sand. Multiple batches of small-scale tests can be conducted, and the optimal production process can be selected and calculated from the large dataset of test results, providing crucial data support for guiding actual production.

[0034] The experimental device of this invention requires no manual operation during operation, reducing labor intensity and eliminating data deviations caused by human inertia.
