Description

A relay transfer and feeding device for toxic and hazardous substances Technical Field

[0001] This invention relates to the field of experimental apparatus, and more specifically, to a relay transfer and feeding device for toxic and hazardous substances. Background Technology

[0002] In modern chemical production and laboratory experiments, there is often a need for the precise and safe transfer of solid and liquid materials, toxic and hazardous materials, and pollutants. Related material transfer technologies have wide applications in laboratories and chemical production, especially in the handling of toxic and hazardous chemicals, where high standards are placed on the sealing, corrosion resistance, and ease of operation of the transfer equipment.

[0003] However, common technologies on the market, especially for the transfer of solid and granular materials, have the following drawbacks: traditional feeding devices have poor sealing performance, which can easily lead to the leakage of toxic and harmful materials. If material transfer is achieved by manual dumping or squeezing, the operation is risky and endangers the health of operators and the safety of the environment. There is also the risk of cross-contamination: non-disposable structures need to be cleaned repeatedly. If the cleaning is not thorough, material residue can easily occur, causing cross-contamination and affecting subsequent production. Although automated feeding systems with robotic arms can reduce manual operation, they are expensive, have complex structures, and are inconvenient to maintain.

[0004] There are currently no good solutions on the market to address the above problems, and there is an urgent need for a new type of relay feeding module to meet the requirements of automation, safety, precision and pollution prevention. Summary of the Invention

[0005] In view of the above-mentioned technical problems in related technologies, the present invention proposes a relay transfer and feeding device for toxic and hazardous substances, which can overcome the above-mentioned shortcomings of the prior art.

[0006] To achieve the above-mentioned technical objectives, the technical solution of the present invention is as follows:

[0007] A relay transfer and feeding device for toxic and hazardous substances includes a housing, a storage bin inserted into the upper part of the housing, a downward-opening base inserted into the lower part of the housing, a feeding hose connected between the storage bin and the base, and the storage bin, the base, and the feeding hose are interconnected.

[0008] The outer casing sidewall is provided with a flow control component that cooperates with the discharge hose.

[0009] Preferably, the flow control assembly includes two symmetrically arranged feeding arms, and the left and right side walls of the housing are provided with insertion interfaces for sliding connection of the feeding arms. The inner end of the feeding arm is inserted into the housing through the insertion interface.

[0010] Preferably, the flow control assembly further includes compression springs and hose clamps symmetrically arranged front and rear; all the compression springs and hose clamps are located within the space enclosed by the storage bin, the outer shell, and the base; the compression spring is clamped between the corresponding side wall of the outer shell and one end of the hose clamp, and the other end of the hose clamp is in close contact with the discharge hose. For example, the compression spring located on the front side is located between the front side wall of the outer shell and the front hose clamp, and the compression spring located on the rear side is located between the rear side wall of the outer shell and the rear hose clamp.

[0011] Preferably, the inner end of the unloading arm is provided with a first inclined surface corresponding to the hose clamp, and the hose clamp is provided with a second inclined surface or trapezoidal island corresponding to the first inclined surface. In implementation, as the unloading arm is inserted deeper into the insertion interface, the first inclined surface will approach and press against the adjacent second inclined surface or trapezoidal island, causing the hose clamps on the front and rear sides to move towards the side wall of the outer casing—that is, away from the unloading hose—thereby loosening the pressure of the hose clamps on the unloading hose.

[0012] Preferably, the unloading arm is provided with several inverted trapezoidal latches corresponding to the insertion interface. Each inverted trapezoidal latch provides a depth gradient for the unloading arm to insert into the housing, but only allows the unloading arm to extend into the insertion interface to a greater depth in a unidirectional manner step by step, and does not allow the unloading arm to be pulled out of the housing through the insertion interface.

[0013] Preferably, the unloading arm is provided with three levels of inverted trapezoidal buckles, corresponding to three levels of insertion depth of the unloading arm relative to the housing. The three levels of insertion depth, from smallest to largest, correspond to the clamped state, throttling state, and fully conductive state of the unloading hose, respectively. When the unloading arm is at the first level of insertion depth, only one inverted trapezoidal buckle is inserted into the connector. At this time, the first inclined surface does not press against the hose clamp, so the unloading arm is fixed to the housing. Moreover, the compression spring and the hose clamp fully press against the unloading hose, so the unloading hose 5 is completely closed and in a clamped state. When the unloading arm is at the second level of insertion depth, two inverted trapezoidal buckles are inserted into the connector. At this time, the first inclined surface partially presses against the hose clamp, and the compression spring and the hose clamp partially press against the unloading hose, so the unloading hose is partially closed and in a throttling state. When the feeding arm is at the third insertion depth, all three inverted trapezoidal buckles are inserted into the insertion interface. At this time, the first inclined surface fully presses the hose clamp. The compression spring, hose clamp and feeding hose are disengaged, and the feeding hose is completely unobstructed and in a fully conductive state.

[0014] Preferably, each of the inverted trapezoidal buckles includes two inverted trapezoidal buckles symmetrically located at the upper and lower parts of the unloading arm.

[0015] Preferably, one end of the hose clamp is provided with a spring slot corresponding to the compression spring, one end of the compression spring extends into the spring slot and the other end presses against the inner side wall of the corresponding housing.

[0016] Preferably, the outer end of the unloading arm is provided with a clamping end.

[0017] Preferably, the outer end of the unloading arm is provided with a baffle, the size of which is larger than the size of the insertion interface. The baffle can prevent the unloading arm from being excessively inserted into the insertion interface, and can also prevent the inner end of the unloading arm from touching and affecting the unloading hose.

[0018] Preferably, the storage silo is a cone-shaped structure that is wider at the top and narrower at the bottom, or a funnel-shaped structure.

[0019] Preferably, the combination of the storage bin, base, and discharge hose is hourglass-shaped.

[0020] Preferably, the feeding hose extends downward into the base. This allows material to be directly fed into the base, and because the base opens downward, it avoids material leakage caused by the feeding hose potentially detaching from the top of the base.

[0021] Preferably, the base includes an open base plate with a discharge bin on the base plate. The discharge bin has a positioning hole for inserting the discharge hose, and the opening of the discharge bin faces downwards. In implementation, the discharge hose can be directly inserted into the discharge bin to connect with the outside, or it can be connected to the outside through the positioning hole of the discharge bin. Toxic and harmful substances, pollutants, and especially chemical substances can be directly transferred and discharged through the storage bin, discharge hose, discharge bin, and base plate.

[0022] The beneficial effects of this product are as follows: This product solves the problems of poor sealing, non-adjustable flow rate, low automation adaptability, and easy cross-contamination in existing technologies, enabling safe, accurate, and efficient operation of discharging toxic and hazardous materials. The overall structure of this product has high sealing performance and safety, with tight fit between components and a sealed outer shell design, effectively preventing the transfer and leakage of toxic and hazardous materials in chemical production or experiments. It ensures a safe operating environment and is suitable for the transfer, transit, and discharging of various liquids, solids, synthetic materials, and reactive materials.

[0023] In this product, the storage silo can be injection molded from a corrosion-resistant material to ensure the purity of the material contact parts. Its shape can be a cone-shaped structure (wider at the top and narrower at the bottom) or a funnel-shaped structure. When the storage silo is cone-shaped or funnel-shaped, its tapered bottom structure allows for seamless connection with the discharge hose. This facilitates the natural convergence of materials to the bottom of the storage silo under gravity and their natural discharge through the hose, reducing the risk of material residue remaining in the storage silo.

[0024] The feeding hose can be made of corrosion-resistant elastic material, which can withstand compression or adapt to a certain degree of bending. The feeding hose is connected to the storage bin and the base to form the feeding path of the material.

[0025] The flow control component can be implemented using existing technology or the preferred solution of this product. It can be formed by the cooperation of a hose clamp and a compression spring, which utilizes the elasticity of the spring on the hose clamp to enable the hose clamp to apply pressure to the discharge hose, thereby achieving the purpose of sealing the discharge hose.

[0026] The outer end of the unloading arm may be equipped with a clamping end, which may have a guide groove to facilitate control by an external robotic arm. This could include gripping and holding the entire unloading arm, inserting it into the guide groove for transport and assembly into the product, or inserting it into the guide groove to push the unloading arm into the housing. Alternatively, the unloading arm can be pushed into the housing manually or by other means. The unloading arm may have several levels of inverted trapezoidal clips to control the depth to which the unloading arm extends into the housing through the insertion interface, thereby controlling the degree of compression of the unloading arm against the hose clamp. The outermost first-level inverted trapezoidal clip secures the unloading arm, while the other inverted trapezoidal clips adjust the diameter of the unloading hose, thus controlling the material flow rate. The clamping design can be customized for different applications. By pushing the hose clamps to both sides through the trapezoidal island at the inner end of the discharge arm, the compression spring and the clamp's tightness on the discharge hose can be adjusted, thus precisely controlling the clamping force and changing the flow cross-sectional area of ​​the discharge pipe to regulate material flow. Testing in different discharge scenarios showed that the flow rate is maximized when pushed to the final stage. The upper part of the outer shell connects to the storage hopper, and the lower part connects to the base. The connections between the outer shell and the storage hopper / base can be sealed with corrosion-resistant and acid / alkali-resistant sealants to further reduce the risk of leakage.

[0027] The base can be made of thick plastic injection molding to ensure stability on the operating table. The base can also be aligned with the positioning hole of the feeding hose, which can be inserted directly downwards into the positioning hole and into the base, making it easier for the robotic arm to be quickly positioned and installed during experiments.

[0028] Compared to existing technologies, this product has the following advantages: (A) Precise flow control: By adjusting the combination of the compression spring and the hose clamp, the material flow can be flexibly and precisely controlled to meet different process requirements. (B) Automated and efficient collaboration: The adaptable design of the base and the robotic arm enables fully automated operation, completely avoiding manual contact with toxic and harmful materials, reducing operational risks while significantly improving production efficiency and automation levels. (C) Elimination of cross-contamination: Its single-use nature means it is directly discarded after use, completely eliminating the traditional model of repeated use requiring cleaning. This fundamentally eliminates the risk of material residue and cross-contamination caused by incomplete cleaning, providing a reliable solution for the strict handling of toxic and harmful materials. (D) Avoidance of cross-contamination: This product can be designed for single use. After completing one material feeding task, it is directly moved by the robotic arm to a dedicated recycling device without cleaning, completely avoiding cross-contamination.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0041] As shown in Figures 1-10, in order to facilitate understanding of the above technical solutions of the present invention, the following describes the above technical solutions of the present invention in detail through specific usage methods.

[0042] A relay transfer and feeding device for toxic and hazardous substances includes a housing 2, a storage bin 1 inserted into the upper part of the housing 2, a downward-opening base 4 inserted into the lower part of the housing 2, a feeding hose 5 connected between the storage bin 1 and the base 4, and the storage bin 1, the base 4, and the feeding hose 5 are connected in communication.

[0043] The outer casing 2 has a flow control component on its side wall that cooperates with the discharge hose 5.

[0044] In one possible embodiment, the flow control assembly includes two symmetrically arranged feeding arms 3, and the left and right side walls of the housing 2 are provided with insertion interfaces 201 for sliding connection of the feeding arms 3. The inner end of the feeding arm 3 is inserted into the housing 2 through the insertion interface 201.

[0045] In one possible embodiment, the flow control assembly further includes compression springs 7 and hose clamps 6 symmetrically arranged front and rear; all the compression springs 7 and hose clamps 6 are located within the space enclosed by the storage bin 1, the outer shell 2, and the base 4; the compression spring 7 is clamped between the corresponding side wall of the outer shell 2 and one end of the hose clamp 6, and the other end of the hose clamp 6 is in close contact with the discharge hose 5. For example, the compression spring 7 located on the front side is located between the front side wall of the outer shell 2 and the front hose clamp 6, and the compression spring 7 located on the rear side is located between the rear side wall of the outer shell 2 and the rear hose clamp 6.

[0046] In one possible embodiment, the inner end of the unloading arm 3 is provided with a first inclined surface 301 corresponding to the hose clamp 6, and the hose clamp 6 is provided with a second inclined surface or trapezoidal island 601 corresponding to the first inclined surface 301. In practice, as the unloading arm 3 is inserted deeper into the insertion interface 201, the first inclined surface 301 will approach and press against the adjacent second inclined surface or trapezoidal island 601, causing the hose clamps 6 on the front and rear sides to move towards the side wall of the outer casing 2—that is, to move away from the unloading hose 5, thereby loosening the pressure of the hose clamps 6 on the unloading hose 5.

[0047] In one possible embodiment, the unloading arm 3 is provided with several inverted trapezoidal latches 302 corresponding to the insertion interface 201. Each inverted trapezoidal latch 302 provides a depth gradient for the unloading arm 3 to insert into the housing 2, but only allows the unloading arm 3 to extend into the insertion interface 201 to a greater depth in a step-by-step unidirectional manner, and does not allow the unloading arm 3 to be pulled out of the housing 2 through the insertion interface 201.

[0048] In one possible embodiment, the unloading arm 3 is provided with three levels of inverted trapezoidal buckles 302, corresponding to three levels of insertion depth of the unloading arm 3 relative to the housing 2. The three levels of insertion depth, from smallest to largest, correspond to the clamped state, throttling state, and fully open state of the unloading hose 5, respectively. When the unloading arm 3 is at the first level of insertion depth, only one inverted trapezoidal buckle 302 is inserted into the insertion port 201. At this time, the first inclined surface 301 does not compress the hose clamp 6, so the unloading arm 3 is fixed to the housing 2, and the compression spring 7 and the hose clamp 6 fully press against the unloading hose 5, so the unloading hose 5 is completely closed and in a clamped state. When the unloading arm 3 is at the second level of insertion depth, two inverted trapezoidal buckles 302 are inserted into the insertion port 201. At this time, the first inclined surface 301 partially compresses the hose clamp 6, and the compression spring 7 and the hose clamp 6 partially press against the unloading hose 5, so the unloading hose 5 is partially closed and in a throttling state. When the feeding arm 3 is at the third insertion depth, all three inverted trapezoidal buckles 302 are inserted into the insertion interface 201. At this time, the first inclined surface 301 fully presses the hose clamp 6. At this time, the compression spring 7, the hose clamp 6 and the feeding hose 5 are disengaged, and the feeding hose 5 is completely unobstructed and in a fully conductive state.

[0049] In one possible embodiment, each of the inverted trapezoidal buckles 302 includes two inverted trapezoidal buckles 302 symmetrically located on the upper and lower parts of the unloading arm 3.

[0050] In one possible embodiment, one end of the hose clamp 6 is provided with a spring slot 602 corresponding to the compression spring 7, one end of the compression spring 7 extends into the spring slot 602 and the other end presses against the inner side wall of the corresponding housing 2.

[0051] In one possible embodiment, the outer end of the unloading arm 3 is provided with a clamping end 304.

[0052] In one possible embodiment, the clamping end 304 is provided with a guide groove 3041.

[0053] In one possible embodiment, the outer end of the feeding arm 3 is provided with a baffle 303, the size of which is larger than the size of the insertion interface 201. The baffle 303 can prevent the feeding arm 3 from being excessively inserted into the insertion interface 201, and can also prevent the inner end of the feeding arm 3 from touching and affecting the feeding hose 5.

[0054] In one possible embodiment, the storage silo 1 is a conical structure or funnel-shaped structure that is wider at the top and narrower at the bottom.

[0055] In one possible embodiment, the combination of the storage bin 1, the base 4, and the discharge hose 5 is hourglass-shaped.

[0056] In one possible embodiment, the feed hose 5 extends downward into the base 4. This allows material to be directly fed into the base 4, and because the base 4 is open downwards, it avoids potential material leakage caused by the feed hose 5 detaching from the top of the base 4.

[0057] In one possible embodiment, the base 4 includes a base plate 401 with an opening, on which a feeding hopper 402 is provided. The feeding hopper 402 has a positioning hole 4021 for the insertion of the feeding hose 5, and the opening of the feeding hopper 402 faces downward. In practice, the feeding hose 5 can pass through the positioning hole 4021 and be directly inserted into the feeding hopper 402 to connect with the outside, or it can be connected to the base 4 by connecting to the edge or inner wall of the positioning hole 4021. Toxic and harmful substances, pollutants, and especially chemical substances can be directly transferred and fed through the storage bin 1, the feeding hose 5, the feeding hopper 402, and the base plate 401.

[0058] In summary, through the aforementioned unique technical solutions, this product solves the problems of poor sealing, non-adjustable flow rate, low automation adaptability, and easy cross-contamination in existing technologies, achieving safe, accurate, and efficient operation for discharging toxic and hazardous materials. The overall structure of this product features high sealing performance and safety, with tight fit between components and a sealed outer shell design, effectively preventing the transfer and leakage of toxic and hazardous materials in chemical production or experiments. This ensures a safe operating environment and is suitable for the transfer, transit, and discharging of various liquids, solids, synthetic materials, and reactive materials.
