Description

Technical Field

[0001] This utility model relates to the field of experimental materials technology, specifically a waste liquid treatment device for natural drug chemical experiments. Background Technology

[0002] In pharmaceutical chemistry experiments, the waste liquid from the experiments cannot be reused due to the presence of impurities and harmful components. Direct discharge of this waste liquid would cause serious environmental pollution. To solve this problem, a dedicated waste liquid treatment device needs to be designed. This device first uses a primary filtration system to effectively separate solid impurities and some harmful substances from the waste liquid, laying the foundation for subsequent advanced treatment. This pretreatment not only reduces the environmental burden but also improves the efficiency of waste liquid treatment, meeting laboratory environmental protection requirements. Through preliminary filtration, the pollution risk of the waste liquid can be significantly reduced, creating conditions for safe discharge or further purification.

[0003] Currently, most existing wastewater treatment devices employ static filtration or centrifugal separation technologies, which are insufficient to meet the gradient separation requirements of complex components in natural medicinal wastewater. Traditional sorting equipment typically uses fixed screens or filter membranes, which are prone to clogging and unable to distinguish between solid wastes of different particle sizes. Furthermore, the constant flow velocity of the wastewater within the device leads to incomplete separation of fine particles from the liquid, affecting subsequent treatment efficiency. While some devices attempt dynamic separation, their complex structures and inability to achieve variable-speed flow of the wastewater reduce sorting efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a waste liquid treatment device for natural product chemistry experiments.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A waste liquid treatment device for natural product chemistry experiments, comprising:

[0007] A horizontally placed liquid storage basin, with a sorting component detachably mounted on its inner bottom surface, the sorting component comprising:

[0008] The sorting barrel is located inside the liquid storage basin and is spaced a distance from the bottom surface of the liquid storage basin. Its periphery is provided with sorting holes that allow liquid waste to pass through.

[0009] The spiral separation mechanism includes a spiral plate and a mesh baffle assembly. The spiral plate is fitted onto the inner wall of the sorting barrel in a variable pitch manner, wherein the axis coincides with the central axis of the sorting barrel, and the pitch of the spiral plate decreases non-linearly from the opening of the sorting barrel downwards.

[0010] The mesh baffle group consists of several mesh baffles, each mesh baffle being fixed to the surface of the spiral plate at different acute angles of inclination.

[0011] The variable pitch design of the spiral plate enables the waste liquid to generate variable speed spiral flow under the action of gravity, thereby achieving gradient separation of solid waste.

[0012] Preferably, the spiral plate is inclined downward from a position near its central axis toward a position near the inner wall of the sorting barrel.

[0013] Preferably, the sorting hole is located on the circumferential side of the sorting barrel near its bottom.

[0015] Preferably, a guide plate is fixed on the surface of the sorting barrel. The guide plate is funnel-shaped and gradually expands outward from the position near the opening of the sorting barrel.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model, by setting a variable pitch spiral plate, enables the waste liquid to generate a variable speed spiral flow. Combined with mesh baffles with different inclination angles and apertures, it can simultaneously achieve the graded separation of solids with different particle sizes, thereby improving the separation efficiency.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] Example

[0028] like Figure 1 As shown, a waste liquid treatment device for natural drug chemical experiments includes a horizontally placed storage basin 1. A sorting component 2 is detachably installed on the bottom surface of the storage basin 1. The sorting component 2 is used to separate the liquid and solid in the waste liquid. After the separation is completed, the solid remains inside the sorting component 2 and the liquid remains inside the storage basin 1.

[0029] Several guide shafts are fixed to the bottom surface of the liquid storage basin 1. A baffle is fixed coaxially to the side of the guide shaft near its top. The diameter of the baffle is larger than the diameter of the guide shaft. It is used to position and support the sorting component 2. The sorting component 2 is detachable for easy cleaning and maintenance.

[0030] Preferred, such as Figure 1-3 As shown, sorting component 2 includes:

[0031] The sorting barrel 3 is set inside the liquid storage basin 1 and is spaced a distance from the bottom surface of the liquid storage basin 1. A fixing ring is fixed on the side of the sorting barrel 3 near the bottom. Several guide grooves are opened through the surface of the fixing ring. The guide grooves are inserted and matched with the top of the guide shaft. The diameter of the guide grooves is the same as the diameter of the guide shaft. When the sorting component 2 is installed, the guide grooves are inserted and matched with the guide shaft, so that the sorting barrel 3 is fixed inside the liquid storage basin 1. The distance between the bottom surface of the sorting barrel 3 and the bottom surface of the liquid storage basin 1 is equal to the distance between the surface of the baffle plate and the bottom surface of the liquid storage basin 1.

[0032] The sorting barrel 3 has a sorting hole 4 that allows liquid waste to pass through its sides. The sorting hole 4 is located on the sides of the sorting barrel 3 near its bottom. When the waste liquid is poured in from the opening at the top of the sorting barrel 3, the solids are sorted first. The waste liquid that has been filtered out of the solids is now only liquid, which flows out from the sorting hole 4 at the bottom and into the liquid storage basin 1, thus achieving solid-liquid separation.

[0033] Preferred, such as Figure 2 As shown, the spiral separation mechanism includes a spiral plate 5 and a mesh baffle assembly;

[0034] The spiral plate 5 is attached to the inner wall of the sorting barrel 3 in a variable pitch manner, wherein the axis coincides with the central axis of the sorting barrel 3, and the pitch of the spiral plate 5 decreases non-linearly from the opening of the sorting barrel 3 downwards. The variable pitch spiral plate 5 design enables the waste liquid to generate a variable speed spiral flow, thereby realizing the gradient separation of solid waste.

[0035] The spiral plate 5 tilts downward from a position near its central axis toward a position near the inner wall of the sorting barrel 3, causing solids to accumulate toward the position near the inner wall of the sorting barrel 3.

[0036] The mesh baffle assembly consists of several mesh baffles 6, each fixed to the surface of the spiral plate 5 at different acute angles. Starting from the surface of the spiral plate 5, the angle between the mesh baffles 6 and the surface of the spiral plate 5 increases as it goes down, and the angle ranges from 45° to 90°. The first layer of mesh baffles 6 has an angle of 45° with the surface of the spiral plate 5, and the angle increases sequentially in the lower layers. The mesh aperture of the mesh baffles 6 decreases sequentially from top to bottom, achieving particle size gradient separation. The upper layer of mesh baffles 6 faces the direction of waste liquid flow, which is more conducive to intercepting solids and preventing solids from rolling off the mesh baffles 6 with the liquid.

[0037] The waste liquid flows downward along the spiral plate 5 under the action of gravity. Due to the non-linear decrease of the pitch (larger at the top and smaller at the bottom), the flow velocity becomes more and more gentle as it goes down, forming a variable speed spiral flow. At the top, most of the solids can be intercepted by the mesh baffle 6. Near the bottom, a small part of the solids with small volume flow with the gentle waste liquid, which is more conducive to being separated by the mesh baffle 6 at the bottom.

[0038] Larger solid particles (such as drug residues) are thrown towards the inner wall of the sorting tank 3 due to their greater inertia during the spiral flow, and slide down the mesh baffle 6 to the lower mesh baffle 6. Smaller solid particles (such as catalyst particles) are intercepted by the mesh baffle 6 with smaller mesh size. Solid-liquid separation of waste liquid does not require an additional power device and relies only on gravity to achieve separation, resulting in low energy consumption.

[0039] Preferred, such as Figure 2 As shown, a guide plate 7 is fixed on the surface of the sorting tank 3. The guide plate 7 is funnel-shaped and gradually expands outward from the position near the opening of the sorting tank 3. The guide plate 7 is funnel-shaped with the opening end facing upward. The outer diameter is slightly smaller than the inner diameter of the liquid storage basin 1 to ensure that the waste liquid flows smoothly into the sorting tank 3 along the guide plate 7 when poured in, avoiding splashing and reducing reagent loss.

[0040] Preferred, such as Figure 1 As shown, a connecting shaft 8 is fixed inside the spiral plate 5. The central axis of the connecting shaft 8 coincides with the central axis of the spiral plate 5, and the connecting shaft 8 is inserted into the bottom of the sorting barrel 3.

[0041] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
