Description

Technical Field

[0001] This utility model relates to the field of vacuum chamber technology, and in particular to an isolation plate type negative pressure vacuum chamber based on negative pressure vacuum technology. Background Technology

[0002] A negative pressure vacuum chamber is a sealed container that uses mechanical equipment to extract internal air, making its internal pressure lower than the external atmospheric pressure. The chamber must be highly sealed to maintain the low-pressure state inside. The system includes: an air extraction system (equipped with a vacuum pump or fan) to extract air and create a negative pressure / vacuum environment; pressure control and monitoring (featuring pressure sensors and a control system for precise control and monitoring of the internal pressure); and safety interlocks (usually equipped with safety devices to ensure the chamber door cannot be easily opened while the internal negative pressure is still present, preventing "explosion" (a shock wave generated by instantaneous pressure equilibrium) or damage to the seal).

[0003] Traditional negative pressure vacuum chambers often employ a fixed chamber structure, or while they may have isolation plates, they lack reliable anti-contamination and quick-disassembly designs. Some equipment uses only simple clips or multiple sets of bolts to connect the isolation plates. On the one hand, bolted connections require tightening each bolt individually during disassembly, which is cumbersome and time-consuming, especially in scenarios where the isolation plates need to be frequently opened for material replacement or internal maintenance, significantly reducing work efficiency. On the other hand, under negative pressure conditions, the isolation plates are prone to loosening due to pressure differences, which may not only cause internal contaminant leakage, threatening the health of operators and the safety of the surrounding environment, but also disrupt the vacuum environment and affect the normal operation of the equipment. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing an isolation plate type negative pressure vacuum chamber based on negative pressure vacuum technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A negative pressure vacuum chamber based on negative pressure vacuum technology includes a chamber body, and an isolation plate is provided on the top of the chamber body.

[0007] The upper side wall of the silo is fixedly connected to a feeding device for material to enter the silo, and the bottom center of the silo is fixedly connected to a draining device for discharging waste from inside the silo.

[0008] Two mounting seats are symmetrically fixed to the outer peripheral wall of the silo body.

The plug rod can be inserted into the socket in the vertical direction, and the side wall of the plug rod has a limit hole.

[0009] The side wall of the mounting base is equipped with a limiting device. The limiting end of the limiting device can be inserted into the socket and cooperate with the limiting hole to realize the positioning of the plug rod in the socket and to detachably lock the isolation plate to the top of the compartment.

[0010] A sealing device is fixed at the bottom edge of the isolation plate. The sealing device is closed along the circumference of the isolation plate to achieve a sealing fit between the isolation plate and the silo body when the isolation plate is locked in place.

[0011] A vacuum device is installed on one side of the chamber. The vacuum device's suction end is connected to the interior of the chamber and is used to extract gas from the chamber to reduce the gas pressure inside the chamber, thereby creating a negative pressure vacuum environment inside the chamber.

[0012] Preferably, the limiting device includes a mounting opening on one side of the mounting base and a limiting rod slidably disposed within the mounting opening. A spring is provided on the outer periphery of the limiting rod, and the two ends of the spring are respectively connected to the interior of the mounting opening and the outer periphery of the limiting rod.

[0013] Preferably, one side of the limiting rod is provided with an inclined surface, which extends from the side near the limiting hole toward the bottom of the limiting rod.

[0019] Preferably, the bottom of the silo body is provided with a discharge hopper, a discharge port is provided on one side of the discharge hopper, and a discharge valve is provided on one side of the discharge port.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This invention, by installing an isolation plate on the top of the chamber, can prevent pollutants from flowing out of the chamber. The outer mounting base, plug-in rod, and limiting device form a stable isolation plate mounting structure, which is more efficient for assembly and disassembly compared to traditional bolt connections. The vacuum device creates negative pressure inside the chamber.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figure 1-6 A negative pressure vacuum chamber based on negative pressure vacuum technology includes a chamber body 1, and an isolation plate 2 is provided on the top of the chamber body 1.

[0031] A feeding device for material to enter the silo 1 is fixedly connected to the upper side wall of the silo 1, and a sewage discharge device for discharging sewage from the silo 1 is fixedly connected to the center of the bottom of the silo 1.

[0032] Two mounting seats 3 are symmetrically fixed to the outer peripheral wall of the silo body 1. The outer peripheral wall of the isolation plate 2 is fixed with a plug rod 4 corresponding to the mounting seat 3. Each mounting seat 3 has a socket 5 adapted to the plug rod 4 at its top. The plug rod 4 can be inserted into the socket 5 in the vertical direction. The side wall of the plug rod 4 has a limit hole 6.

[0033] The side wall of the mounting base 3 is equipped with a limiting device. The limiting end of the limiting device can be inserted into the socket 5 and cooperate with the limiting hole 6 to realize the positioning of the plug rod 4 in the socket 5 and to detachably lock the isolation plate 2 to the top of the compartment 1.

[0034] A sealing device is fixed at the bottom edge of the isolation plate 2. The sealing device is closed along the circumference of the isolation plate 2 to achieve a sealing fit between the isolation plate 2 and the compartment 1 when the isolation plate 2 is locked to the compartment 1.

[0035] A vacuum device 25 is provided on one side of the chamber 1. The vacuum device 25 is connected to the interior of the chamber 1 and is used to extract the gas inside the chamber 1 to reduce the gas pressure inside the chamber 1 and create a negative pressure vacuum environment inside the chamber 1.

[0036] When in use, this device prevents pollutants from flowing out of the chamber 1 by setting an isolation plate 2 on the top of the chamber 1. The outer mounting base 3, plug rod 4 and limiting device form a stable installation structure for the isolation plate 2, which is more efficient in assembly and disassembly compared to traditional bolt connections. The vacuum device 25 creates a negative pressure inside the chamber 1. As the negative pressure is formed, the solenoid valve opens quickly, and the excrement is sucked into the vacuum chamber through the feed port 12 under the action of strong adsorption force. The sealing device effectively fills the gap between the isolation plate 2 and the chamber 1, preventing external air from entering or pollutants from flowing out of the chamber 1.

[0037] In the example of this application, the limiting device includes a mounting port 7 disposed on one side of the mounting base 3 and a limiting rod 8 slidably disposed in the mounting port 7. A spring 9 is disposed on the outer periphery of the limiting rod 8, and the two ends of the spring 9 are respectively connected to the interior of the mounting port 7 and the outer periphery of the limiting rod 8.

[0038] As a preferred example of this utility model, the mounting port 7 and the sliding limit rod 8 cooperate to form a telescopic limit structure. During operation, simply pushing the limit rod 8 is sufficient to fix or unlock the plug rod 4. Compared with traditional snap-fit ​​or threaded connections, the operation steps are simpler, greatly improving the efficiency of disassembly and assembly of the isolation plate 2. The outer spring 9 can automatically reset the limit rod 8 using its own elasticity. When the plug rod 4 is inserted into the socket 5, the spring 9 can push the limit rod 8 to automatically engage with the limit hole 6, eliminating the need for manual alignment and further simplifying the operation process. At the same time, the elasticity of the spring 9 can always keep the limit rod 8 and the limit hole 6 in close contact, effectively improving the structural reliability of the isolation plate 2 after installation.

[0039] In the example of this application, an inclined surface 26 is provided on one side of the limiting rod 8, and the inclined surface 26 extends from the side near the limiting hole 6 toward the lower part of the limiting rod 8.

[0040] As a preferred example of this utility model, when the plug rod 4 is inserted into the limiting hole 6 and aligned with the limiting rod 8, the return force of the spring 9 will push the limiting rod 8 to slide along the mounting opening 7. At this time, the reverse angle of the inclined surface 26 can guide the limiting rod 8 to be accurately embedded in the limiting hole 6. During the process of the inclined surface 26 contacting the inner cavity of the limiting hole 6, the contact between the slope structure and the inner wall of the limiting hole 6 will generate a slight downward force. This force can help the isolation plate 2 to further adhere to the top of the compartment 1.

[0041] In the example of this application, the sealing device includes a sealing ring 10 disposed below the isolation plate 2, and a groove 11 is provided on the top of the chamber 1, the groove 11 being adapted to the sealing ring 10.

[0042] As a preferred example of this utility model, the sealing device adopts a structural design in which the sealing ring 10 and the groove 11 are adapted to each other. Compared with the planar seal, the groove 11 can play a positioning role for the sealing ring 10, preventing the sealing ring 10 from shifting during installation or use, and ensuring accurate sealing position. The sealing ring 10 itself has good elastic deformation capability. When the isolation plate 2 is closed, the sealing ring 10 will tightly fill the groove 11 under the pressure of the isolation plate 2, and at the same time form a multi-faceted fit seal with the bottom of the isolation plate 2 and the inner wall of the groove 11, which greatly improves the sealing area and sealing strength. It can effectively block external air, dust and other impurities from entering the chamber, and prevent the internal vacuum environment from leaking, ensuring a stable and lasting negative pressure state in the chamber. At the same time, during the process of the inclined surface 26 contacting the inner cavity of the limiting hole 6, the contact between the slope structure and the inner wall of the limiting hole 6 will generate a slight downward component force. This component force can help the sealing ring 10 be pressed tightly, improving the sealing performance of the isolation plate 2 and the groove 11.

[0043] In the example of this application, the feeding device includes a feed port 12 opened on one side of the hopper 1, and a pneumatic ball valve 13 is provided on the feed port 12.

[0044] As a preferred example of this utility model, the feeding device adopts a design combining the feed inlet 12 and the pneumatic ball valve 13. The pneumatic ball valve 13 has the characteristics of fast opening and closing speed and good sealing performance. Compared with manual valves, it can achieve automated operation through pneumatic control. It can be linked with the control system of the production line to achieve precise control of the feeding process. For example, the valve can be automatically opened or closed according to the amount of material in the bin to avoid excessive material conveying and causing contaminant blockage.

[0045] In the example of this application, the sewage discharge device includes a discharge head 14 disposed at the bottom of the silo body 1, and a one-way check valve 15 is disposed on one side of the discharge head 14.

[0046] As a preferred example of this utility model, the sewage discharge device achieves directional discharge of waste material in the silo through the cooperation of the discharge head 14 and the one-way check valve 15. The structural design of the discharge head 14 can guide the waste material or sewage to flow in a designated direction, avoiding spillage or residue during the discharge process. The core function of the one-way check valve 15 is to prevent external media from flowing back into the silo. During sewage discharge, the pressure inside the silo can push the check valve to open, completing the sewage discharge operation. After the sewage discharge is completed, the check valve will automatically close under its own structure or external pressure, effectively preventing external air, sewage or impurities from entering the silo through the discharge port.

[0047] In the example of this application, a cleaning device is provided below the isolation plate 2. The cleaning device includes a support input pipe 17 provided below the isolation plate 2 for connecting to an external water source. A connecting pipe 18 is provided at the bottom end of the support input pipe 17. A plurality of water outlet pipes 19 are provided on the outer periphery of the connecting pipe 18. A plurality of nozzles 20 are provided on each of the plurality of water outlet pipes 19.

[0048] As a preferred example of this utility model, the water source is connected to the external water source through the connecting pipe 18, and the water flow can be transformed into a columnar water flow through the nozzles 20 on the several water outlet pipes 19 set around the outer periphery of the connecting pipe 18. The high-pressure water flow can effectively wash away stubborn stains and residual materials attached to the inner wall of the chamber, improve the cleaning effect, and at the same time, the water mist cleaning can reduce water consumption and reduce water resource consumption.

[0049] In the example of this application, a vacuum pressure gauge 21 is provided on the isolation plate 2, and the detection end of the vacuum pressure gauge 21 is located inside the chamber 1.

[0050] As a preferred example of this utility model, the vacuum pressure gauge 21 installed on the cover plate can display the vacuum pressure value inside the chamber in real time and intuitively. Operators do not need to obtain pressure data through complex testing equipment or indirect calculations. They can quickly grasp the pressure status inside the chamber and promptly determine whether the vacuum environment meets the usage requirements.

[0051] In the example of this application, a discharge bin 22 is provided at the bottom of the bin 1, a discharge port 23 is provided on one side of the discharge bin 22, and a discharge valve 24 is provided on one side of the discharge port 23.

[0052] As a preferred example of this utility model, the discharge hopper 22 added to the bottom of the hopper 1 provides a transition space for the storage and discharge of materials, avoiding the problem of blockage or uneven discharge when pollutants are discharged directly from the bottom of the hopper 1; the discharge port 23 on one side of the discharge hopper 22 cooperates with the discharge valve 24 to realize the controllable discharge of materials. The operator can control the discharge speed and discharge amount of pollutants by adjusting the opening of the discharge valve 24 according to production needs.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
