Description

Technical Field

[0002] Before, during and in the subsequent environmental monitoring phase of landfilling hazardous waste, in order to ensure that the landfill operation complies with relevant standards and effectively protects environmental quality, it is necessary to conduct detailed sampling and analysis of the hazardous waste itself and the surrounding environment of the landfill. This requires us to conduct strict testing of the waste landfill environment and the hazardous waste itself before burial.

[0003] First, due to the internal structural design of the waste detection sample mixing sample preparation device, these sample preparation devices are prone to poor results, uneven mixing, and even agglomeration when mixing samples. This may seriously affect the representativeness of the sample and the accuracy of the test results. Secondly, the removal steps of the existing sample preparation device after collecting environmental samples are too cumbersome, which increases the complexity of the operation. At the same time, in the process of removing soil samples, it is easy for samples to fall or scatter, which may not only cause sample loss, but also cause secondary pollution to the environment, resulting in the existing waste detection sample mixing sample preparation device being difficult to quickly put into the mixing sample preparation instrument after sampling, which reduces work efficiency to a certain extent.

[0015] A method for using a sample mixing sample preparation device for backfilling a hazardous waste cave comprises the following steps: S1. When in use, the device needs to be moved to the position to be detected, and then the conical barrel is inserted into the designated position and the motor is started. The motor is operated to gradually drill into the ground, and the sampling is completed after sufficient underground samples are obtained; S2. When sampling is required, the conical barrel needs to be inserted into the ground, and the control component is adjusted to loosen the connection with the bottom of the sample preparation component. Then, the power component is driven by the operation of the motor and the outer cylinder and the conical barrel are synchronously driven to rotate. At this time, the outer cylinder will drive the control component, the adjustment component and the inner cylinder to rotate in the same direction through the gear block, so that the device gradually drills into the ground and collects the sample soil. After the collection is completed, the device needs to be taken out from the ground. When sampling is required, the locker and the door panel need to be opened to place the external sample preparation instrument with the entrance facing downward in the inner tank. At this time, the conical barrel is vertically upward and the control component is adjusted to be fixed under the sample preparation component. At this time, the motor is started. At this time, the motor will drive the outer cylinder and the gear block to rotate, and the gear block will drive the control component to rotate. At the same time, the control component will drive the first gear to rotate in the opposite direction, so that the spiral blade rotates in the opposite direction and gradually pushes the collected soil into the external sample preparation instrument below; S2.1. When sampling is required, the conical barrel needs to be inserted into the ground, and the control component needs to be adjusted to loosen the connection with the bottom of the sample preparation component. Then, the power component is driven by the operation of the motor and the outer barrel and the conical barrel are driven to rotate synchronously. At this time, the outer barrel will drive the second gear and the inner barrel to rotate through the gear block. Since the mounting seat can slide outside the slide plate, the second gear will drive the lower seat to move in a circle under the gear block and synchronously drive the first gear and the outer barrel to rotate in the same direction. At this time, the outer barrel, the inner barrel and the spiral blades will rotate in the same direction while collecting and punching holes downward to collect sample soil; S2.2. When sample preparation is required, the locker and door panel need to be opened to place the external sample preparation instrument with the inlet facing downwards in the inner tank. At this time, the conical barrel should be placed vertically upwards and the positioner should be adjusted to fix it under the sample preparation tube to prevent the slide from sliding under the sample preparation tube. At this time, the motor will drive the outer tube and the gear block to rotate. At the same time, since the positioner will fix the position of the mounting seat, the second gear cannot make a circular motion and can only rotate on its own. Therefore, while the gear block drives the second gear to rotate, the second gear will also drive the first gear to rotate in the opposite direction, so that the first gear will discharge the material into the sample preparation tube through the spiral blade when it rotates.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is designed with an adjustment component, a control component and a spiral blade. When sampling is required, the conical barrel needs to be inserted into the ground, and the control component is adjusted to loosen the connection with the bottom of the sample preparation component. Then, the power component is driven by the operation of the motor and the outer cylinder and the conical barrel are synchronously driven to rotate. At this time, the outer cylinder drives the control component, the adjustment component and the inner cylinder to rotate in the same direction through the gear block, so that the device gradually drills into the ground and collects the sample soil. After the collection is completed, the device needs to be taken out from the ground. When sampling is required, the locker and the door panel need to be opened to place the inlet of the external sample preparation instrument in the inner tank downward. At this time, the conical barrel is vertically upward and the control component is adjusted to be fixed under the sample preparation component. At this time Start the motor, and the motor will drive the outer cylinder and the gear block to rotate. The gear block will drive the control component to rotate, and the control component will drive the first gear to rotate in the opposite direction, so that the spiral blades will rotate in the opposite direction and gradually push the collected soil into the external sample preparation instrument below. This allows the device to not only avoid leakage of soil when it is pulled out during soil collection, but also quickly discharge the collected sample soil into the external sample preparation instrument. On the one hand, this can avoid soil leakage and environmental pollution. On the other hand, the above solution can quickly take out the sample soil and directly send it to the external sample preparation instrument, thereby improving the working efficiency of the device.

[0017] 2. The present invention also designs a control component and a movable component. When sampling is required, the conical barrel needs to be inserted into the ground, and the control component is adjusted to loosen the connection with the bottom of the sample preparation component. Then, the power component is driven by the operation of the motor and the outer cylinder and the conical barrel are driven to rotate synchronously. At this time, the outer cylinder will drive the second gear and the inner cylinder to rotate through the tooth block. Since the mounting seat can slide outside the slide plate, the second gear will drive the lower seat to move in a circle through the tooth block and synchronously drive the first gear and the outer cylinder to rotate in the same direction. At this time, the outer cylinder, the inner cylinder and the spiral blades will rotate in the same direction while collecting the sample soil by punching holes downward, so that the device can collect the soil in the inner cylinder while the spiral blades rotate in the same direction as the outer cylinder when in use, avoiding the soil in the inner cylinder from falling when the device is pulled out, avoiding secondary pollution to the environment by the device, and reducing the difficulty of using the device.

[0018] 3. The present invention also designs a control component, a sampling component and a spiral blade. When sampling is required, the locker and the door panel need to be opened to place the external sample preparation instrument with the inlet facing downward in the inner tank. At this time, the conical barrel is vertically upward and the positioner is adjusted to fix it under the sample preparation tube to prevent the slide plate from sliding under the sample preparation tube. At this time, the motor is started. At this time, the motor will drive the outer tube and the gear block to rotate. Since the positioner will fix the position of the mounting seat, the second gear cannot make a circular motion and can only rotate on its own. Therefore, while the gear block drives the second gear to rotate, the second gear will also drive the first gear to rotate in the opposite direction, so that the first gear discharges the material into the sample preparation tube through the spiral blade when rotating. On the one hand, the device can complete the collection and discharge of materials by only controlling the placement angle and the start and close of the positioner, thereby reducing the difficulty of using the device and improving the popularization of the device. On the other hand, the device can inject the collected materials into the external sample preparation instrument, which can prevent personnel from directly contacting the sample soil and hazardous waste, thereby playing a role in ensuring the safety of personnel.
