Description

Technical Field

[0001] The utility model relates to the technical field of filtration and dust removal, in particular to a vacuum filtration material collection device. Background Art

[0002] A vacuum drying oven is a drying device designed specifically for drying heat-sensitive, easily decomposable, and easily oxidizable substances. It can be filled with inert gas inside and is especially suitable for quickly drying items with complex components.

[0003] When drying materials in a vacuum drying oven, it is necessary to use a vacuum device to extract the vaporized moisture in the materials. Some tiny materials will be sucked away by the vacuum device along with the water vapor. Over time, these tiny materials will deposit in the pipeline and the vacuum device, thus affecting the normal operation of the vacuum device and even causing damage to the vacuum device in severe cases. Summary of the Utility Model

[0004] In order to reduce the materials deposited in the vacuum device during the vacuum pumping process, the present application provides a vacuum filtration material collection device.

[0005] A vacuum filtration material collection device provided by the present application adopts the following technical solutions:

[0006] A vacuum filtration material collection device includes a housing. A chamber is provided inside the housing. An air suction pipe communicating with the chamber is provided on the housing. An exhaust pipe and multiple filter elements are provided on the housing. One end of the filter element is connected to the housing, and the other end of the filter element penetrates through the housing and extends into the exhaust pipe. A filtering through hole for the filter element to pass through is provided on the housing, and the filtering through hole communicates with the exhaust pipe. Tiny filter holes for materials to pass through are provided on the surface of the filter element. A material cylinder communicating with the chamber is further connected to the bottom of the housing. A control member for controlling the opening and closing of the material cylinder and the chamber is provided on the housing.

[0007] By adopting the above technical solutions, during the vacuum pumping process by the vacuum device, tiny materials will enter the chamber along with the water vapor through the air suction pipe. The gas entering the chamber is filtered by the filter element and then discharged from the exhaust pipe. The materials following the water vapor into the chamber will be filtered by the filter element and slide down from the filter holes to the bottom of the chamber. The control member is used to make the materials falling to the bottom of the chamber fall into the material cylinder for collection, so that the chamber is not likely to accumulate materials and it is convenient to collect these materials. In addition, through the setting of the filter holes on the filter element, the filter element is not likely to accumulate materials, effectively extending the service life of the device.

[0008] Preferably, an anti-blowing air bag is provided on the exhaust pipe. A blowing air pipe corresponding to the filter element is connected and communicated with the anti-blowing air bag. The end of the blowing air pipe away from the anti-blowing air bag penetrates through the exhaust pipe and extends into the exhaust pipe.

[0009] By adopting the above technical solution, blowing gas into the chamber through the back-blowing air bag can remove the materials attached to the surface of the filter element and extend the service life of the filter element.

[0010] Preferably, both the filter element and the blowing pipe are inclined, the blowing pipe is located on the extension line of the filter element, and the end of the filter element far from the exhaust pipe is lower than the end of the filter element close to the exhaust pipe in the vertical direction.

[0011] By adopting the above technical solution, due to the inclined setting of the filter element, during the vacuum pumping process, the materials filtered by the filter element are not easily accumulated at the end of the filter element close to the exhaust pipe, enabling the normal use of the device and extending the service life of the device.

[0012] Preferably, the inner diameter of the chamber at the connection between the housing and the cartridge decreases sequentially in the direction towards the cartridge.

[0013] By adopting the above technical solution, the materials falling to the bottom of the chamber can move along the inner wall of the chamber and accumulate above the cartridge, facilitating the subsequent collection of the materials.

[0014] Preferably, a sealing ring is embedded at the end of the filter element close to the exhaust pipe, and the sealing ring is in tight contact with the inner wall of the filtering through-hole.

[0015] By adopting the above technical solution, through the setting of the sealing ring, the sealing performance of the device is improved, so that the materials are not easily moved from the gap between the filter element and the filtering through-hole to the exhaust pipe, and there is no easy accumulation of materials at the exhaust pipe.

[0016] Preferably, a heating chamber is further provided on the wall thickness of the housing, a feed pipe connected and communicated with the heating chamber is provided at one end of the housing close to the cartridge, and a discharge pipe connected and communicated with the heating chamber is provided at one end of the housing far from the cartridge.

[0017] By adopting the above technical solution, the heating medium enters the heating chamber from the feed pipe and is then discharged from the discharge pipe. Through the setting of the heating medium located in the heating chamber, the water vapor inhaled into the chamber is not easily liquefied, and the stability of the exhaust performance of the device is improved.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1. The materials following the water vapor into the chamber will be filtered by the filter element, slide down from the filter holes to the bottom of the chamber, and can be moved out of the chamber through the cartridge for collection, so that the chamber is not easily filled with materials and it is convenient to collect these materials. In addition, through the setting of the filter holes on the filter element, there is no easy accumulation of materials on the filter element, effectively extending the service life of the device;

[0020] 2. By setting the filter element obliquely, during the vacuum pumping process, the materials filtered by the filter element are not easily accumulated at one end of the filter element close to the exhaust pipe, enabling the normal use of the device, further reducing the accumulation of materials, and prolonging the service life of the device.

[0024] The following is a further detailed description of the present utility model in conjunction with the attached Figure 1-2 drawings.

[0025] The embodiment of the present application discloses a vacuum filtering material collection device for reducing the materials deposited in a vacuum device during the vacuum pumping process. Referring to Figure 1 , it includes a housing 1. A chamber 11 is provided inside the housing 1. A maintenance pipe 2 communicating with the chamber 11 is fixedly provided on the housing 1. Maintenance personnel can enter the chamber 11 through the maintenance pipe 2 to clean the residual materials in the chamber 11 or perform maintenance on the vacuum device.

[0026] Referring to Figure 1 and Figure 2 , an air suction pipe 3 communicating with the chamber 11 is also fixedly provided on the housing 1. During the vacuum pumping process by a vacuum device, tiny materials will enter the chamber 11 along with water vapor through the air suction pipe 3. An exhaust pipe 4 and multiple filter elements 5 are fixedly provided on the housing 1. The multiple filter elements 5 are uniformly arranged along the height direction of the housing 1. In the embodiment of the present application, six filter elements 5 are provided. One end of the filter element 5 is fixed to the housing 1, and the other end of the filter element 5 penetrates through the housing 1 and extends into the exhaust pipe 4. A filtering through hole for the filter element 5 to pass through is provided on the housing 1. The filtering through hole communicates with the exhaust pipe 4. The gas entering the chamber 11 is filtered by the filter element 5 and then discharged from the exhaust pipe 4.

[0027] The filter element 5 used in this application is a new type of filter material with high strength and overall rigidity, which is made of multiple layers of metal sintered mesh. It is formed by special laminated pressing of multiple layers of stainless steel mesh and vacuum sintering. There are many tiny filter holes on its surface for the material to pass through. During the vacuum pumping process, the material that enters the chamber 11 along with the water vapor will be filtered by the filter element 5 and slide down from the filter holes to the bottom of the chamber 11, so that there is no easy accumulation of material on the filter element 5, effectively extending the service life of the device.

[0028] Referring to Figure 1 , both the filter element 5 and the blowing pipe 61 are inclined. The blowing pipe 61 is located on the extension line of the filter element 5. The end of the filter element 5 far from the exhaust pipe 4 is lower than the end of the filter element 5 close to the exhaust pipe 4 in the vertical direction. Then, during the vacuum pumping process, the material filtered by the filter element 5 is not easy to accumulate at the end of the filter element 5 close to the exhaust pipe 4, enabling the device to work properly and extending the service life of the device.

[0029] Referring to Figure 1 , a material cylinder 7 communicating with the chamber 11 is fixedly connected to the bottom of the housing 1. The material falling to the bottom of the chamber 11 can move to the material cylinder 7 for collection. A control member for controlling the opening and closing of the communication between the material cylinder 7 and the chamber 11 is provided on the housing 1. In the embodiment of this application, the control member is selected as a butterfly valve 71. Through the setting of the butterfly valve 71, when the vacuum device is working, the material cylinder 7 and the bottom of the chamber 11 can be kept in a closed state.

[0030] Referring to Figure 1 and Figure 2 , a reinforcing cylinder member 51 for strengthening the overall strength of the filter through-hole is fixedly provided on the inner wall of the filter through-hole. A sealing ring 52 is embedded at the end of the filter element 5 close to the exhaust pipe 4, and the sealing ring 52 abuts against the inner wall of the reinforcing cylinder member 51. Through the setting of the sealing ring 52, the sealing performance of the device is improved, so that the material is not easy to move from the gap between the filter element 5 and the filter through-hole to the exhaust pipe 4, and there is no easy accumulation of material at the exhaust pipe 4.

[0031] Referring to Figure 1 , an anti-blowing air bag 6 is provided on the exhaust pipe 4. A blowing pipe 61 corresponding to the filter element 5 is connected and communicated with the anti-blowing air bag 6. The end of the blowing pipe 61 far from the anti-blowing air bag 6 penetrates through the exhaust pipe 4 and extends into the exhaust pipe 4. The anti-blowing air bag 6 is used to inject compressed air into the filter element 5 through the blowing pipe 61, so as to be able to remove the material attached to the surface of the filter element 5 and extend the service life of the filter element 5.

[0032] Referring to Figure 1 , the inner diameter of the chamber 11 at the connection between the housing 1 and the material cylinder 7 gradually decreases in the direction towards the material cylinder 7. Then, the material falling to the bottom of the chamber 11 can move along the inner wall of the chamber 11 and accumulate above the material cylinder 7, facilitating the subsequent collection of the material.

[0033] Referring to Figure 1 , a heating chamber 12 is further provided on the wall thickness of the housing 1. One end of the housing 1 close to the barrel 7 is provided with a feed pipe 13 connected and communicated with the heating chamber 12, and one end of the housing 1 far from the barrel 7 is provided with a discharge pipe 14 connected and communicated with the heating chamber 12. The heating medium enters the heating chamber 12 from the feed pipe 13 and then is discharged from the discharge pipe 14. Through the arrangement of the heating medium in the heating chamber 12, the water vapor in the suction chamber 11 is not easily liquefied, and the stability of the exhaust performance of the device is improved.

[0034] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
