Abstract

The material receiving device comprises a material receiving groove body, a positioning frame body, an inductive switch, a container, a first pipeline and a second pipeline. The material receiving groove body is configured with a material receiving port for receiving liquid. The positioning frame body is independently arranged with the material receiving groove body. A telescopic tray is movably connected in the positioning frame body. An elastic member is arranged between the telescopic tray and the positioning frame body, and the positioning frame body can support the telescopic tray through the elastic member. The inductive switch is arranged below the telescopic tray and can be triggered by the telescopic tray. The container is placed on the telescopic tray and cooperates with the gap of the peripheral wall of the positioning frame body. The first pipeline has an inlet and an outlet, which are in communication with the material receiving groove body. A liquid pumping pump is arranged on the first pipeline. The second pipeline is arranged in parallel with the first pipeline and is in communication with the container. In this way, on the one hand, the detection accuracy can be improved; on the other hand, the inductive switch is prevented from directly contacting the strongly corrosive liquid, and expensive high-protection contact switches are not needed, thereby effectively controlling the cost.

Description

Technical Field

[0001] This utility model belongs to the technical field of experimental equipment, and in particular relates to a material receiving device. Background Technology

[0002] In the testing and handling of highly corrosive liquids, the inherent corrosive properties of the liquid itself mean that any leakage or seepage can pose a serious threat to equipment, the environment, and personnel safety. Therefore, it is essential to equip the system with dedicated receiving devices to catch any potential leaks, effectively preventing spills and avoiding corrosive damage, environmental pollution, or safety accidents.

[0003] Currently, most common material receiving devices use non-contact inductive switches to detect changes in the liquid level inside the container, thereby determining whether to activate the receiving or alarm function. However, this detection method has significant drawbacks in practical applications: on the one hand, the inductive switches are susceptible to interference from liquid splashes, leading to false triggering and unreliable detection results; on the other hand, in some situations, due to factors such as liquid flow patterns, container structure, or installation location, the inductive switches may fail to trigger properly, resulting in the risk of missed detections. While using high-protection-level contact inductive switches that can directly contact the liquid can improve reliability to some extent, its manufacturing and maintenance costs increase significantly, making it less economical in scenarios requiring frequent use or large-scale deployment. Utility Model Content

[0004] In view of this, it is necessary to provide a receiving device for solving the above-mentioned technical problems.

[0005] A receiving device, comprising: The receiving tank has a receiving port for receiving liquids. A positioning frame is set independently of the receiving trough. A telescopic tray is movably connected inside the positioning frame. An elastic element is provided between the telescopic tray and the positioning frame, and the positioning frame can support the telescopic tray through the elastic element. An inductive switch is located below the telescopic tray and can be triggered by the telescopic tray; The container is placed on the telescopic tray and fits with the peripheral wall of the positioning frame with a clearance. The first pipeline has an inlet and an outlet, and the inlet and the outlet are simultaneously connected to the receiving tank. A liquid pump is installed on the first pipeline. The second pipeline is arranged in parallel with the first pipeline, and the second pipeline is connected to the container; The receiving device has a first state and a second state. When the receiving device is in the first state, the liquid pump can pump the liquid in the receiving tank into the container through the second pipeline. When the receiving device is in the second state, the telescopic tray closes the second pipeline and triggers the induction switch, and the liquid pump returns the liquid drawn from the receiving tank to the receiving tank.

[0006] In one embodiment, the telescopic tray is provided with a flow-blocking protrusion, which can squeeze the portion of the second pipeline located in the positioning frame under the action of the telescopic tray to close the second pipeline.

[0007] In one embodiment, the second conduit is configured as a hose.

[0008] In one embodiment, the telescopic tray is provided with a top rod, and the telescopic tray can trigger the inductive switch through the top rod; The elastic element is fitted onto the top rod.

[0009] In one embodiment, the elastic element is configured as a compression spring.

[0010] In one embodiment, the first pipeline is connected to the second pipeline and a connection point is formed therebetween; The first pipeline is equipped with a damping valve at the location between the connection point and the outlet.

[0011] In one embodiment, the positioning frame is provided with legs, and the positioning frame can be placed flat on the ground by means of the legs; The positioning frame is connected downward to a support frame, which is housed within the area where the support leg is located, and is used to house the inductive switch.

[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The receiving device claimed in this application achieves multiple functions by placing a container filled with liquid on a telescopic tray supported by an elastic element. Specifically, when the liquid in the container reaches a preset weight, the elastic element is compressed, causing the telescopic tray to sink, which triggers the sensor switch below and activates an alarm, while also shutting down the second pipeline. This avoids the false triggering and missed detection problems caused by liquid splashing and ambient light, which are common with traditional non-contact sensor switches, thus improving detection accuracy. Furthermore, since the sensor switch is located below the container, it avoids direct contact with highly corrosive liquids, eliminating the need for expensive, high-protection-level contact switches and effectively controlling costs. Simultaneously, after the alarm is triggered, the liquid pump automatically returns the liquid in the receiving tank through the first pipeline, forming a self-circulation system. This not only promptly eliminates the risk of overflow but also allows the receiving device to continue operating without interrupting drainage, improving equipment continuity and operational safety.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] The receiving device 100 claimed in this application is used to receive liquids generated during testing and processing, which are highly corrosive liquids, such as concentrated sulfuric acid.

[0020] like Figure 1 As shown, the receiving device 100 provided in this application includes a receiving tank 10, a positioning frame 20, a sensor switch 30, a container 40, a first pipeline 50, and a second pipeline 60. The receiving tank 10 is equipped with a receiving port 11 for receiving liquids (not shown in the figure). The positioning frame 20 is set independently of the receiving tank 10. A telescopic tray 21 is movably connected inside the positioning frame 20. An elastic element 22 is provided between the telescopic tray 21 and the positioning frame 20, and the positioning frame 20 can support the telescopic tray 21 through the elastic element 22. The sensor switch 30 is located below the telescopic tray 21 and can be triggered by the telescopic tray 21. The container 40 is placed on the telescopic tray 21 and is fitted with the peripheral wall 201 of the positioning frame 20. The first pipeline 50 has an inlet 501 and an outlet 502, both of which are connected to the receiving tank 10. A liquid pump 51 is installed on the first pipeline 50. The second pipeline 60 is connected in parallel with the first pipeline 50 and is connected to the container 40. The receiving device 100 has a first state and a second state. When the receiving device 100 is in the first state, the liquid pump 51 can pump the liquid in the receiving tank 10 to the container 40 through the second pipeline 60. When the receiving device 100 is in the second state, the telescopic tray 21 closes the second pipeline 60 and triggers the induction switch 30, and the liquid pump 51 returns the liquid drawn from the receiving tank 10 to the receiving tank 10.

[0021] As can be seen from the above, the receiving device 100 of this application achieves multiple functions by placing the liquid-containing container 40 on the telescopic tray 21 supported by the elastic element 22. Specifically, when the liquid in the container 40 reaches a preset weight, the elastic element 22 is compressed, causing the telescopic tray 21 to sink, which triggers the lower inductive switch 30 and alarms, and also shuts down the second pipeline 60. In this way, on the one hand, the problems of false triggering and missed detection caused by liquid splashing and ambient light in traditional non-contact inductive switches can be avoided, thus improving the detection accuracy; on the other hand, since the inductive switch 30 is located below the container 40, it avoids direct contact with highly corrosive liquids, eliminating the need for expensive high-protection-level contact switches and effectively controlling costs; at the same time, after the receiving device 100 triggers the alarm, the liquid pump 51 can automatically return the liquid in the receiving tank 10 through the first pipeline 50 to form a self-circulation, which can not only eliminate the risk of overflow in time, but also allow the receiving device 100 to continue to operate without interrupting the liquid discharge, which is conducive to improving the continuity of equipment use and operational safety.

[0022] It should be noted that the receiving device 100 of this application is designed with a preventive triggering mechanism. When the liquid level in the container 40 reaches more than half of its capacity, it will drive the telescopic tray 21 to trigger the induction switch 30 and issue an alarm to prevent overflow accidents caused by overfilling when the liquid in the container 40 is manually recovered later. In addition, the receiving device 100 fully considers the actual working conditions: on the one hand, the amount of liquid dripping from the receiving port 11 into the receiving tank 10 is usually limited and the accumulation rate is slow, providing sufficient time for operators to calmly complete the recovery and replacement of the full container 40; on the other hand, the liquid pump 51 adopts an intermittent working mode (i.e., it starts and works for a period of time at intervals), and this energy-saving and reasonable design further ensures the reliability and continuity of the entire system operation.

[0023] like Figure 1 As shown, in one embodiment, the positioning frame 20 is provided with a support leg 202, and the positioning frame 20 can be placed flat on the ground by the support leg 202 to achieve the purpose of supporting the positioning frame 20.

[0024] Here, the number of support legs 202 is configured to be four. The four support legs 202 are located at the four corners of the positioning frame 20 and are tilted outward relative to the positioning frame 20 to improve the stability of the positioning frame 20 when it is placed on the ground.

[0025] like Figure 1 As shown, in this embodiment, the positioning frame 20 is connected downward to a support frame 203, which is housed within the area where the support leg 202 is located, and is used to house the inductive switch 30. That is, the inductive switch 30 is specifically placed inside the support frame 203 of the positioning frame 20, so as to facilitate the installation of the inductive switch 30 into the positioning frame 20.

[0026] Here, the inductive switch 30 can be a limit linear switch, a proximity switch, or a micro switch, etc., which will not be elaborated here.

[0027] like Figure 1 As shown, in one embodiment, the telescopic tray 21 is provided with a flow-blocking protrusion 211, which can squeeze the portion of the second pipeline 60 located inside the positioning frame 20 under the action of the telescopic tray 21 to close the second pipeline 60.

[0028] Specifically, as the liquid in container 40 continues to accumulate, its overall weight gradually increases, continuously exerting downward pressure on the telescopic tray 21 below, causing the telescopic tray 21 to compress the elastic element 22 at the bottom and sink downward; during this process, the telescopic tray 21 drives the intercepting protrusion 211 on it to gradually squeeze the second pipe 60, causing the channel for liquid flow in the second pipe 60 to continuously narrow until the liquid flow path is completely blocked.

[0029] Here, the flow-stopping protrusion 211 can use its arc surface to compress the second pipe 60. To achieve precise flow control, a groove (not shown) corresponding to the flow-stopping protrusion 211 can be provided in the positioning frame 20; when the telescopic tray 21 sinks, the flow-stopping protrusion 211 first presses the second pipe 60 into the groove, and then the arc surface and the groove work together to compress the pipe wall of the second pipe 60, ultimately cutting it off completely to achieve closure.

[0030] In this embodiment, the flow-blocking protrusion 211 and the telescopic tray 21 adopt an integrated structure, ensuring the integrity and reliability during linkage. At the same time, the second pipeline 60 is designed as a rubber hose, which, by utilizing its unique elastic deformation capability, can meet the usage requirements of being repeatedly squeezed and cut by the flow-blocking protrusion 211 and elastically returning to its original position after the pressure is removed.

[0031] like Figure 1 As shown, in one embodiment, the telescopic tray 21 is provided with a top rod 212, and the telescopic tray 21 can trigger the inductive switch 30 through the top rod 212. An elastic element 22 is fitted onto the top rod 212. This serves two purposes: firstly, the top rod 212 provides radial restraint for the elastic element 22, ensuring it can continuously and stably apply elastic support force to the telescopic tray 21; secondly, it allows the telescopic tray 21 to accurately trigger the inductive switch 30 below through the top rod 212 during movement.

[0032] Here, the elastic element 22 is configured as a compression spring. Of course, in other embodiments, the elastic element 22 may also be configured as a rubber pad, packing, etc., which will not be elaborated here.

[0033] like Figure 1As shown, in one embodiment, the first pipeline 50 is connected to the second pipeline 60 and forms a connection point 101; wherein, a damping valve 52 is provided on the first pipeline 50 at the location between the connection point 101 and the outlet 502.

[0034] Here, the damping valve 52 presets a certain flow resistance in the first pipeline 50 for the path of liquid flowing to the outlet 502. Therefore, when the second pipeline 60 is unobstructed, the liquid drawn by the pump 51 from the receiving tank 10 will preferentially flow to the second pipeline 60, which has less resistance; once the second pipeline 60 is cut off, the pressure in the pipeline system increases, and the liquid will overcome the resistance of the damping valve 52, causing it to open, thereby forming a circulation path that returns to the receiving tank 10 through the first pipeline 50.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
