Description

Technical Field

[0001] The utility model relates to the technical field of vacuuming, in particular to a vacuuming device for auxiliary feeding. Background Art

[0002] After the production of highly viscous fluids such as rubber and paint, or even paste-like materials, in the production workshop, the storage container is generally not directly aligned with the discharge port of the material production reactor to directly pour the material into the storage container for storage. The reason is that on the one hand, the discharge port of the material production reactor is located at a high position, making it difficult to directly store the storage container. On the other hand, there are still raw materials that have not yet reacted completely in the material production reactor, and it is possible to transfer the raw materials that have not yet reacted completely to the storage container. Therefore, the discharge port of the material production reactor is generally connected to a transportation pipeline, through which the materials in the material production reactor are transported and poured into the storage container for storage. When the storage container for viscous materials has only one port available, the need for vacuuming and feeding can be met.

[0003] However, due to the slow flow rate of viscous materials, during the process of material infusion and storage, the speed at which the materials flow from the material production reactor into the transport pipeline and the flow rate in the transport pipeline are both very slow, which results in a long time for the materials to be transferred to the storage container. This not only consumes a lot of extra time, but some specific types of materials may also oxidize and deteriorate if exposed to the air for a long time, affecting the quality of the materials. Utility Model Content

[0004] The utility model provides a vacuum pumping device for auxiliary feeding to solve the problem that the flow rate of viscous materials is slow and a lot of time is wasted in the process of transferring viscous materials to a storage container with only one opening in the above-mentioned prior art solution. The vacuum pumping device in the solution can make the receiving storage container of the viscous material perform material filling and vacuuming work at the same time, can reduce the air pressure in the storage container, and thus speed up the filling speed of the viscous material.

[0005] The technical scheme adopted by the utility model is: a vacuum pumping device for auxiliary feeding, comprising a material conduit, a vacuum conduit and a vacuum pump, one end of the material conduit is used to communicate with a material conveying pipeline, and the other end is used to extend into the inner cavity of a storage container, the vacuum conduit is sleeved on the material conduit, a branch pipe is provided on the side wall of the vacuum conduit, one end of the branch pipe is communicated with the inner cavity of the vacuum conduit, and the other end is communicated with the vacuum pump, a mounting portion for blocking the vacuum conduit is provided on the material conduit, one end of the vacuum conduit is fixedly connected to the mounting portion, and the other end is used to be connected to a feeding port of the storage container.

[0006] Before material filling and storage, first connect one end of the material conduit to the material conveying pipeline, and extend the other end into the inner cavity of the storage container. Then adjust the position of the storage container so that one end of the vacuum conduit can be fixedly connected to the mounting portion, and the other end is connected to the feed port of the storage container. After all connections are completed, discharge the material so that the material can flow along the material conveying pipeline to the inner cavity of the storage container. After discharging, turn on the vacuum pump, which will extract the air in the storage container through the branch pipe and the vacuum conduit. After the air in the storage container is extracted, the pressure in the storage container decreases. After the pressure in the storage container decreases, the pressure difference will accelerate the filling speed of the material in the material conveying pipeline into the storage container, shortening the time required for the material to be filled into the storage container, so that the storage container with only one port available can be vacuumed and fed at the same time.

[0007] The auxiliary feeding vacuum device in the present scheme can realize vacuuming the inner cavity of the storage container while the viscous material is being poured into the storage container with only one opening, thereby reducing the pressure in the storage container. The speed of pouring the viscous material into the storage container is accelerated by the pressure difference between the inside and outside of the storage container, saving the pouring time of the viscous material when storing it, and realizing the storage container with only one opening being used while vacuuming and feeding. At the same time, it can also reduce the contact between the material and the air, and avoid the material being exposed to the air for a long time, which may cause the material to oxidize and deteriorate, affecting the quality of the material.

[0008] Preferably, the shortest distance d between the outer wall of the material conduit and the inner wall of the vacuum conduit is 3mm-5mm. During vacuuming, the gas in the storage container enters the vacuum pump along the gap between the outer wall of the material conduit and the inner wall of the vacuum conduit. The size of the gap between the outer wall of the material conduit and the inner wall of the vacuum conduit will affect the efficiency of vacuuming. The larger the gap, the higher the vacuuming efficiency. However, the larger the gap, the easier it is to draw sticky materials into the gap. Experiments have shown that when the shortest distance d between the outer wall of the material conduit and the inner wall of the vacuum conduit is between 3mm-5mm, it will not affect the vacuuming efficiency and can also prevent sticky materials from entering the gap. The shortest distance d between the outer wall of the material conduit and the inner wall of the vacuum conduit can be selected according to actual applications.

[0009] Preferably, the shortest distance m between the inner side wall of the branch pipe and the end of the material conduit connected to the feed port of the storage container in the axial direction of the material conduit is 25mm-50mm. The shortest distance n between the inner side wall of the branch pipe and the end of the vacuum conduit connected to the mounting portion in the axial direction of the material conduit is 0-15mm. The distance between the inner side wall of the branch pipe and the end of the material conduit connected to the feed port of the storage container will directly affect the vacuuming effect of the vacuum pump. When the distance is too long, the vacuuming effect is poor, but when the distance is too short, it will be easy to draw the viscous material into the branch pipe. It has been confirmed by experiments that when the shortest distance m between the inner side wall of the branch pipe and the end of the material conduit connected to the feed port of the storage container in the axial direction of the material conduit is between 25mm-50mm, it can not only ensure a good vacuuming effect, but also prevent the viscous material from being drawn into the branch pipe. The specific example can be selected according to actual needs. When the distance between the inner wall of the branch pipe and the end of the vacuum duct connected to the mounting portion is too long, the vacuuming effect will also be affected. Experimental measurements have shown that the vacuuming effect will not be affected when the shortest distance n between the inner wall of the branch pipe and the end of the vacuum duct connected to the mounting portion in the axial direction of the material duct is between 0-15mm. The specific example can be selected according to actual needs.

[0010] Preferably, one end of the material conduit for communicating with the material conveying pipeline, one end of the vacuum conduit for communicating with the storage container, and one end of the branch pipe connected to the vacuum pump are all fixedly connected with a first flange connector. A first sealing ring is provided on the first flange connector, and the first sealing ring is fixedly connected to the first flange connector. The connection between the conduit and the material conveying pipeline, the vacuum pump, and the storage container is completed by the first flange connector, which can effectively ensure the strength and air tightness of the connection. The provision of the first sealing ring can further enhance the overall air tightness after the connection, so that the vacuuming effect is better.

[0011] Preferably, a second flange connector is provided at one end of the vacuum duct for connection with the mounting portion, and the mounting portion is fixedly connected to the second flange connector. A second sealing ring is provided on the second flange connector, and the second sealing ring is fixedly connected to the second flange connector, and the second sealing ring fits tightly with the mounting portion. The vacuum duct is fixedly connected to the mounting portion through the second flange connector. This connection method can not only improve the connection strength between the vacuum duct and the mounting portion, but also increase the airtightness between the vacuum duct and the mounting portion. The second sealing ring can further increase the airtightness between the vacuum duct and the mounting portion, avoiding air leakage when the vacuum machine is evacuating the vacuum.

[0012] Preferably, the axis of the material conduit is a straight line. When the axis of the material conduit is a straight line, it can effectively ensure that the viscous material in the material conveying pipeline can smoothly enter the storage container along the material conduit.

[0013] Preferably, the axis of the material conduit is L-shaped, and the L-shaped material conduit includes a horizontal section and a vertical section, the horizontal section is used to communicate with the material conveying pipeline, and the vertical section is used to extend into the inner cavity of the storage container, and the mounting portion and the vacuum conduit are both located on the vertical section. When the material conduit is L-shaped, the placement direction of the storage container can be changed, and it is more convenient to place the storage container vertically.

[0014] Compared with the prior art, the beneficial effect of the utility model lies in that the auxiliary feeding vacuum device in the present scheme can realize the vacuum operation of the inner cavity of the storage container while the viscous material is poured into the storage container with only one usable opening, thereby reducing the pressure in the storage container, accelerating the speed of pouring the viscous material into the storage container through the pressure difference, saving the pouring time of the viscous material when storing it, and realizing the vacuum feeding of the storage container with only one usable opening, and at the same time reducing the contact between the material and the air, avoiding the oxidation and deterioration of the material due to long-term exposure of the material to the air, affecting the quality of the material.

[0022] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0023] Example 1

[0024] like Figure 1-Figure 2 The embodiment 1 of a vacuum pumping device for auxiliary feeding is shown, comprising a material conduit 1, a vacuum conduit 2 and a vacuum pump 3. One end of the material conduit 1 is used to communicate with a material conveying pipeline 4, and the other end is used to extend into the inner cavity of a storage container 5. The vacuum conduit 2 is sleeved on the material conduit 1. A branch pipe 6 is provided on the side wall of the vacuum conduit 2. One end of the branch pipe 6 is communicated with the inner cavity of the vacuum conduit 2, and the other end is communicated with the vacuum pump 3.

One end of the vacuum conduit 2 is fixedly connected to the mounting portion 101, and the other end is used to connect to the feed port of the storage container 5. The storage container 5 is a material storage tank.

[0025] The working principle or working process of this embodiment is as follows: when the storage container has only one opening available, before material filling and storage, first connect one end of the material conduit 1 to the material conveying pipe 4, and extend the other end into the inner cavity of the storage container 5, and then adjust the position of the storage container 5 so that one end of the vacuum conduit 2 can be fixedly connected to the mounting portion 101, and the other end is connected to the feed port of the storage container 5. After all the connections are completed, discharge the material so that the material can flow along the material conveying pipe 4 to the inner cavity of the storage container 5. After discharging the material, turn on the vacuum pump 3, which will remove the air in the storage container 5 through the branch pipe 6 and the vacuum conduit 2. After the air in the storage container 5 is extracted, the pressure in the storage container 5 decreases.

[0026] The beneficial effects of this embodiment: the auxiliary feeding vacuum pumping device in this scheme can realize the vacuum pumping work on the inner cavity of the storage container 5 at the same time when the viscous material is poured into the storage container 5 with only one opening, thereby reducing the pressure in the storage container 5, and accelerating the speed of pouring the viscous material into the storage container 5 through the pressure difference, saving the pouring time of the viscous material when storing, and realizing the storage container with only one opening that can be used while vacuuming and feeding, and at the same time can also reduce the contact between the material and the air, avoiding the material from being exposed to the air for a long time, resulting in oxidation and deterioration of the material, affecting the quality of the material.

When the shortest distance m between the inner wall of the branch pipe 6 and the end of the material conduit 1 connected to the feed port of the storage container 5 in the axial direction of the material conduit 1 is between 25mm-50mm, it can not only ensure a good vacuuming effect, but also prevent the viscous material from being drawn into the branch pipe 6. When the shortest distance n between the inner wall of the branch pipe 6 and the end of the vacuum conduit 2 connected to the mounting portion 101 in the axial direction of the material conduit 1 is between 0-15mm, it will not affect the vacuuming effect. The connection between the conduit and the material conveying pipeline 4, the vacuum pump 3 and the storage container 5 is completed by the first flange connector 7, which can effectively ensure the strength and airtightness of the connection.
