Description

Technical Field

[0001] This utility model relates to the field of soil pretreatment technology, and in particular to a soil pretreatment device for environmental monitoring that facilitates the removal of impurities. Background Technology

[0002] Soil sample pretreatment is a technical process that uses decomposition and extraction methods to ensure that the form and concentration of the components to be tested meet the detection requirements and to reduce coexisting interferences. Decomposition methods are used for elemental determination. They release elements by breaking down the soil mineral lattice and organic matter. Common methods include acid decomposition and autoclave closed decomposition. Acid decomposition uses a mixed acid system such as HCl-HNO3-HF-HClO4 and requires controlled heating conditions to avoid loss.

[0003] An existing soil pretreatment device for environmental monitoring that facilitates the removal of impurities results in significant splashing of the product during the screening process, making it difficult to provide effective protection during screening. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a soil pretreatment device for environmental monitoring that facilitates the removal of impurities.

[0005] This utility model is achieved by the following technical solution: a soil pretreatment device for environmental monitoring that facilitates the removal of impurities, including a soil pretreatment box, a supporting shell fixedly connected to the rear end of the soil pretreatment box, a drive motor snapped onto the top of the supporting shell, a transmission shaft fixedly connected to the output end of the drive motor, and a toggle plate fixedly connected to the surface of the transmission shaft.

[0006] A fixed support plate is fixedly connected to the top of the inner wall of the soil pretreatment box, and an impurity screening frame is fixedly connected to the bottom of the fixed support plate. The impurity screening frame has screening holes inside. A control cabinet is fixedly connected to the right end of the soil pretreatment box. A feed pipe is fixedly connected to the inside of the soil pretreatment box. A rotating seat is fixedly connected to the front of the impurity screening frame. A sealing cover plate is hinged inside the rotating seat. A blocking baffle is inserted into the front of the soil pretreatment box. A guide plate is fixedly connected to the inner wall of the soil pretreatment box.

[0007] Through the above technical solution, two fixed support plates symmetrically distributed on the left and right sides provide stable support for the screening frame, and the screening holes at the bottom of the frame, together with the stirring action of the agitator, enable continuous screening operation.

[0008] As a further improvement to the above solution, the number of fixed support plates is set to two, and the two fixed support plates are symmetrically distributed on the left and right sides with the impurity screening frame as the center. The impurity screening frame is located inside the soil pretreatment box.

[0009] As a further improvement to the above solution, the number of the actuating support plates is set to several, and the several actuating support plates are equidistantly distributed around the drive shaft, and the actuating support plates are located inside the impurity screening frame.

[0010] Through the above technical solution, the support plate is moved deep into the impurity screening frame to forcefully turn and break up the soil sample, so that the soil clods are fully separated from the impurities.

[0011] As a further improvement to the above solution, the feed pipe is fixedly connected to the top of the impurity screening frame, the feed pipe is located at the top of the actuating support plate, and the feed pipe is located at the top of the drive shaft.

[0012] Through the above technical solution, the modular combination of the fixed support plate and the screening frame supports the replacement of screens with different aperture sizes, adapts to diverse monitoring needs, greatly reduces operational complexity, and improves equipment utilization.

[0013] As a further improvement to the above solution, the rear end of the sealing cover plate contacts the front surface of the impurity screening frame, and the front surface of the guide plate contacts the front surface of the blocking baffle.

[0014] As a further improvement to the above solution, the blocking baffle is located on the front of the impurity screening frame, and the blocking baffle is located on the front of the sealing cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention features a sealing cover with a hinged rotating seat that is in close contact with the front of the impurity screening frame, forming an openable dust cover. When the cover is closed during operation, it effectively suppresses dust and protects the health of operators. When the machine is stopped, it is opened to facilitate cleaning of the screen. By setting a blocking baffle on the front of the screening frame, it works in conjunction with the guide plate to form a double barrier, preventing material from splashing out during processing. This not only meets laboratory environmental protection standards but also avoids cross-contamination that could affect test results.

[0017] This invention features a feed pipe vertically fixed to the top of the impurity screening frame, allowing materials to fall directly into the agitation area via the pipe, thus avoiding secondary pollution caused by manual feeding. The agitation support plate, located at the top of the drive shaft, creates a top-down spiral motion trajectory, extending the material's residence time in the screening area. A guide plate directs the undersize material out of the screen, forming a sealed channel with the baffle plate to prevent fine particles from scattering. This ensures that impurities of different particle sizes are collected in stages, meeting the stringent requirements for sample purity in environmental monitoring. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figure 1-4 This embodiment provides a soil pretreatment device for environmental monitoring that facilitates the removal of impurities. It includes a soil pretreatment box 1, a supporting shell 2 fixedly connected to the rear end of the soil pretreatment box 1, a drive motor 3 snapped onto the top of the supporting shell 2, a transmission shaft 4 fixedly connected to the output end of the drive motor 3, and a moving support plate 5 fixedly connected to the surface of the transmission shaft 4.

[0027] A fixed support plate 8 is fixedly connected to the top of the inner wall of the soil pretreatment box 1. An impurity screening frame 6 is fixedly connected to the bottom of the fixed support plate 8. Screening holes 7 are opened inside the impurity screening frame 6. A control cabinet 9 is fixedly connected to the right end of the soil pretreatment box 1. A feed pipe 10 is fixedly connected to the inside of the soil pretreatment box 1. A rotating seat 11 is fixedly connected to the front of the impurity screening frame 6. A sealing cover plate 12 is hinged inside the rotating seat 11. A blocking baffle plate 13 is inserted into the front of the soil pretreatment box 1. The inner wall is fixedly connected with a guide plate 14. The rear end of the sealing cover 12, which is hinged to the rotating seat 11, is in close contact with the front of the impurity screening frame 6, forming an openable dust cover. When working, closing the cover can effectively suppress dust and protect the health of operators. When stopping the machine, opening it makes it easy to clean the screen. The sealing baffle 13 is set on the front of the screening frame, which works with the guide plate 14 to form a double barrier to prevent material from splashing out during the process. This not only meets the laboratory environmental protection standards, but also avoids cross-contamination that may affect the test results.

[0028] Two symmetrically distributed fixed support plates 8 provide stable support for the screening frame, and the screening holes 7 at the bottom of the plates work in conjunction with the stirring action of the agitator to achieve continuous screening operation.

[0029] The number of fixed support plates 8 is set to two. The two fixed support plates 8 are symmetrically distributed on the left and right sides with the impurity screening frame 6 as the center. The impurity screening frame 6 is located inside the soil pretreatment box 1.

[0030] The number of actuating support plates 5 is set to several, and the several actuating support plates 5 are equidistantly distributed around the transmission shaft 4. The actuating support plates 5 are located inside the impurity screening frame 6.

[0031] The support plate 5 is pushed deeper into the impurity screening frame 6 to forcefully turn over and break up the soil sample, so that the soil clods are fully separated from the impurities.

[0032] The feed pipe 10 is fixedly connected to the top of the impurity screening frame 6. The feed pipe 10 is located at the top of the actuating support plate 5 and the top of the drive shaft 4.

[0033] The modular combination of the fixed support plate 8 and the screening frame allows for the replacement of screens with different aperture sizes, adapting to diverse monitoring needs, significantly reducing operational complexity, and improving equipment utilization.

[0034] The rear end of the sealing cover plate 12 contacts the front surface of the impurity screening frame 6, and the front surface of the guide plate 14 contacts the front surface of the blocking baffle 13. By setting the feed pipe 10 vertically fixed to the top of the impurity screening frame 6, the material falls directly into the agitation area through the pipe, avoiding secondary pollution caused by manual feeding. By setting the agitation support plate 5 at the top of the drive shaft 4, a spiral motion trajectory from top to bottom is formed, which prolongs the residence time of the material in the screening area. By setting the guide plate 14, the undersize material is guided to be discharged in a directional manner, forming a closed channel with the blocking baffle 13 to prevent fine particles from scattering, ensuring that impurities of different particle sizes are collected in stages, and meeting the stringent requirements of environmental monitoring for sample purity.

[0035] The blocking baffle 13 is located on the front of the impurity screening frame 6 and on the front of the sealing cover 12.

[0036] The implementation principle of the soil pretreatment device for environmental monitoring that facilitates the removal of impurities in this embodiment is as follows: A sealing cover 12 hinged to a rotating base 11 is in close contact with the front of the impurity screening frame 6, forming an openable dust cover. Closing the cover during operation effectively suppresses dust and protects the health of operators. Opening it when the machine is stopped facilitates cleaning of the screen. A sealing baffle 13 located on the front of the screening frame, in conjunction with the guide plate 14, forms a double barrier to prevent material splashing during processing. This meets laboratory environmental standards and avoids cross-contamination. To mitigate the impact on test results, the feed pipe 10 is vertically fixed to the top of the impurity screening frame 6, allowing materials to fall directly into the agitation area via the pipe, thus avoiding secondary contamination caused by manual feeding. The agitation support plate 5, located at the top of the drive shaft 4, forms a top-down spiral motion trajectory, extending the residence time of the material in the screening area. The guide plate 14 guides the undersize material to be discharged in a directional manner, forming a closed channel with the blocking baffle 13 to prevent fine particles from scattering. This ensures that impurities of different particle sizes are collected in stages, meeting the stringent requirements for sample purity in environmental monitoring.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
