Description

Technical Field

[0001] This utility model relates to the technical field of material storage and discharging equipment, and in particular to a negative pressure material storage and discharging device with lighting. Background Technology

[0002] A negative pressure storage and discharge device is a type of equipment that utilizes the principle of negative pressure for material storage, conveying, and discharge. Its working principle includes: negative pressure formation, where air is extracted from the storage device using vacuum pumps, Roots blowers, or other negative pressure power equipment, creating a negative pressure state within the device and a pressure difference with the external atmospheric pressure.

[0003] Material is drawn in from the feed inlet into the conveying pipe under the action of pressure difference, and a material-air mixture is formed in the pipe, which is then transported to the storage device along with the airflow.

[0004] In the process of gas-material separation and discharge, after the material enters the storage device, it undergoes gas-material separation through a filtration device, etc. The air is extracted, and the material falls to the bottom of the device for storage due to gravity. When discharge is required, the valve of the discharge port is opened, and the material flows out from the discharge port under the action of gravity.

[0005] Traditional material storage devices have the following technical problems:

[0006] 1. There are blind spots in observation. After the lighting components have been used for a long time, the lampshade of the conventional window will become contaminated. In low-light environments, it is not possible to clearly observe the material accumulation state, which can easily lead to problems such as bridging and clumping.

[0007] 2. There is a cleaning defect. Its internal lighting components are easily covered by dust. Traditional wiping methods require stopping the machine to disassemble, which affects continuous production.

[0008] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] To address the aforementioned shortcomings, the purpose of this utility model is to provide a negative pressure material storage and discharging device with lighting, which can ensure that the negative pressure flowing gas can be used as the driving force to clean the lampshade by setting up a structure that automatically cleans the lampshade of the lighting structure.

[0010] To achieve the above objectives, this utility model provides a negative pressure storage and discharging device with lighting, comprising: a storage tank with a discharge port at the bottom; a cover plate disposed on the top of the storage tank, the cover plate having a feed port and a negative pressure port, an lighting element disposed at the bottom of the cover plate, a cleaning element for cleaning the outside of the lighting element being sleeved on the outside of the lighting element, and an active driving element being rotatably connected inside the negative pressure port, the active driving element rotating to drive the cleaning element to clean the lighting element.

[0011] According to the present invention, the active driving component of the negative pressure storage and discharging device with illumination includes:

[0012] Rotate the drive fan blades connected inside the negative pressure port;

[0013] A drive gear ring rotates synchronously with the drive fan blades. The bottom of the drive gear ring engages with the cleaning component. The rotation of the drive gear ring causes the cleaning component to rotate.

[0014] According to the present invention, the cleaning component of the negative pressure storage and discharging device with illumination includes:

[0015] A rotating sleeve is rotatably connected to the lampshade of the lighting component. The outer side of the rotating sleeve is provided with a driven gear ring, which cooperates with the driving gear ring.

[0016] The driven gear ring has a scraper inside, and the scraper is in close contact with the bottom of the lampshade.

[0017] According to the present invention, in the negative pressure storage and discharging device with illumination, the driving fan blade and the driving gear ring are connected by a connecting shaft, and the driving gear ring and the connecting shaft are connected by a connecting rod.

[0018] According to the present invention, the cover plate is provided with a filter screen corresponding to the negative pressure port on the inner side of the storage tank, and the filter screen is sleeved on the bottom of the negative pressure port.

[0019] According to the present invention, the negative pressure storage and discharging device with illumination has an opening on the top side wall of the filter screen, and the driving gear ring is correspondingly arranged with the opening, and the driving gear ring and the driven gear ring mesh at the opening.

[0020] In summary, the technical effects achieved by this utility model are:

[0021] 1. By setting up a filter structure to filter the negative pressure port, the material sucked in under negative pressure can be effectively filtered, ensuring the separation of gas and material, and achieving the effect of negative pressure feeding.

[0022] 2. By setting up a structure for cleaning the lampshade, it is ensured that during use, the active drive component can be driven to rotate by the negative pressure gas flow, thereby driving the cleaning component to rotate and further clean the lampshade, ensuring the cleanliness of the lampshade and optimizing the lighting effect.

[0031] See Figure 1 and Figure 2This utility model provides a negative pressure storage and discharging device with illumination. The device includes a storage tank 5 with a discharge port 5 at its bottom, ensuring that powdered material inside the tank can be discharged. A cover plate 1 is located on top of the storage tank 5, with an inlet 3 and a negative pressure port 2. The negative pressure port 2 is connected to a negative pressure mechanism, ensuring that during use, negative pressure is introduced through the mechanism, drawing the material connected to the inlet 3 into the storage tank 5, completing the automatic feeding process. An illumination element is located at the bottom of the cover plate 1, facilitating subsequent illumination within the storage tank 5. The storage tank 5 has a viewing cover on its side wall, which allows observation of the material inside and provides lighting for observation. It also provides an ultraviolet disinfection lamp to disinfect the material inside the storage tank 5, thereby reducing resource waste during steam disinfection. The lighting element is covered with a cleaning element 9 to clean the outside of the lighting element. The cleaning element 9 cleans the lamp cover 6 of the lighting element. The negative pressure port 2 is rotatably connected to an active drive element 7. The active drive element 7 rotates to drive the cleaning element 9 to clean the lighting element. The active drive element 7 drives the cleaning element 9, reducing the increased cost caused by setting up a separate drive element.

[0032] In one exemplary embodiment, the storage tank 4 adopts a double-layer 304L stainless steel cylinder (inner diameter Φ800mm±5mm, effective volume 1.2m³), the inner wall is mirror polished (roughness Ra≤0.4μm), the outer wall is sandblasted with an anti-stick layer (thickness 50μm), and the bottom is equipped with a 60° conical guide structure (cone surface tilt angle tolerance ±1°), which is seamlessly connected to the pneumatic butterfly valve (DN50, ISO5211 standard flange) of the discharge port 5.

[0033] Preferably, in one exemplary embodiment of this example, combined with Figure 3 The active drive component 7 includes:

[0034] The drive fan blade 72 is rotatably connected inside the negative pressure port 2. By setting the drive fan blade 72, which can be made of titanium alloy and has a 6-blade oblique flow design (tilt angle 45°, blade tip gap ≤0.5mm), negative pressure is provided in the negative pressure port 2. When air is discharged from the negative pressure port 2, the flowing gas at this time pushes the drive fan blade 72 to rotate, thereby realizing the rotation of the drive fan blade 72 without drive.

[0035] The drive gear ring 73 rotates synchronously with the drive fan blade 72. The bottom of the drive gear ring 73 engages with the cleaning component 9. The rotation of the drive gear ring 73 drives the cleaning component 9 to rotate. The drive gear ring 73 is fixedly connected to the drive fan blade 72. When the drive fan blade 72 is subjected to force and rotates, it drives the drive gear ring 73 to rotate synchronously, which facilitates the subsequent driving of the cleaning component 9, thereby completing the cleaning process of the lamp cover 6.

[0036] Additionally, in one exemplary embodiment, combined with Figure 4 Cleaning component 9 includes:

[0037] A rotating sleeve is rotatably connected to the lampshade 6 of the lighting component. The outer side of the rotating sleeve is provided with a driven gear ring 91. The driven gear ring 91 cooperates with the driving gear ring 73 to ensure that the driven gear ring 91 rotates synchronously through the rotation of the driving gear ring 73.

[0038] The driven gear ring 91 has a scraper 92 inside. The scraper 92 can be made of food-grade silicone material (Shore hardness 65A, contact pressure 0.15N / mm²). The scraper 92 is in close contact with the bottom of the lamp cover 6. While the driven gear ring 91 drives the scraper 92 to rotate, it scrapes and washes the surface of the lamp cover 6, thereby completing the cleaning process of the lamp cover 6.

[0039] Furthermore, in one exemplary embodiment of this example, the drive fan blade 72 and the drive gear ring 73 are connected by a connecting shaft 74, and the drive gear ring 73 and the connecting shaft 74 are connected by a connecting rod. The drive fan blade 72 and the drive gear ring 73 are connected by the connecting shaft 74, ensuring that the drive gear ring 73 can be directly made on the driven gear ring 91. At the same time, the outer limiting ring 71 of the drive fan blade 72 can be directly replaced by the drive gear ring 73, and the drive fan blade 72 can be directly set at the position of the driven gear ring 91, reducing the need for the connecting shaft 74.

[0040] In one exemplary embodiment, the cover plate 1 is provided with a filter screen 8 corresponding to the negative pressure port 2 on the inner side of the storage tank 4. The filter screen 8 is sleeved on the bottom of the negative pressure port 2 and is configured as a filter cylinder structure to ensure that it can directly cover and block the negative pressure port 2. At the same time, the top side wall of the filter screen 8 is provided with an opening, and the drive gear ring 73 is correspondingly provided with the opening. The drive gear ring 73 and the driven gear ring 91 mesh at the opening to ensure that the driven gear ring 91 inside the filter screen 8 can mesh with the drive gear ring 73 to complete the transmission process.

[0041] Further, see Figure 2To ensure the gas and solid separation effect of filter 8, filter 8 can adopt a multi-layer composite filtration structure: outer layer: 316L stainless steel woven mesh (mesh count 100, porosity 42%); middle layer: PTFE microporous membrane (pore size 0.5μm, air permeability >10L / cm²·min); inner layer: titanium alloy support skeleton (honeycomb structure, porosity 85%), to ensure the separation effect of gas and solid.

[0042] When using, combine Figures 1-4 The material is connected to the negative pressure supply mechanism through the negative pressure port 2. Then, the negative pressure supply mechanism supplies negative pressure to the inside of the storage tank 5. At this time, the material connected to the feed port 3 is directly sucked into the inside of the storage tank 5 under the pressure of the negative pressure gas. After the material enters the inside of the storage tank 5, the gas is sucked away from the filter screen 8 under the action of negative pressure. Then, the material and gas are separated under the action of the filter screen 8. The material falls into the inside of the storage tank 5. At the same time as the gas passes through the negative pressure port 2, the gas flow acts on the drive fan blade 72. The drive fan blade 72 is pushed to rotate by the reaction force. At the same time as the drive fan blade 72 rotates, it drives the drive gear ring 73 and the driven gear ring 91 to rotate, cleaning the surface of the lamp cover 6, thereby ensuring that the lighting component can provide sufficient illumination to the inside of the tank.

[0043] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
