Description

Technical Field

[0001] The present invention relates to the technical field of pneumatic conveying, and particularly relates to a dense-phase conveying tank structure. Background Art

[0002] Gas dense-phase transportation refers to a transportation process in which hydrocarbons such as ethane, propane, and butane produced in a gas field are kept in a gaseous state and transported through a single-phase pipeline together with methane in a gaseous state all the time. It is a kind of wet natural gas pipeline transportation process containing condensate. Most gas pipelines transport dry natural gas, that is, the above-mentioned heavy hydrocarbons (referred to as condensate) are removed at the gas field to avoid their condensation during transportation, so as to always maintain single-phase transportation, which can save energy consumption compared with two-phase transportation. However, for this purpose, a fractionation device for removing condensate needs to be built at the gas field, and the condensate also needs to be transported to the consumption area;

[0003] There is also dense-phase transportation in the pneumatic transportation of solids. Fixed dense-phase transportation refers to a way of closely transporting bulk materials in a pipeline. In dense-phase transportation, the product will not be suspended in the air because the transported material is either too heavy or highly abrasive, and a relatively high air flow velocity needs to be maintained. This means that the product will be transported in the form of "waves", "plugs" or "strands", resulting in less wear. Therefore, dense-phase transportation is more suitable for fragile products. Existing products need to be pressurized in the tank before transportation, and then transported through a pipeline, usually from the bottom end of the tank;

[0004] However, in the actual application process, the bottom end of the dense-phase transportation tank is conical. Due to the sharp change in pressure at the tip of the cone, condensation is likely to occur. If dense-phase transportation is carried out during condensation, it will cause wear on the inner wall of the pipeline. Moreover, if the solid material itself has high viscosity, there will also be a risk of pipeline adhesion, which greatly reduces the efficiency of dense-phase transportation. Summary of the Invention

[0005] The present invention aims at the deficiencies in the prior art and provides a dense-phase conveying tank structure.

[0006] In order to solve the above technical problems, the present invention is solved by the following technical solutions

[0007] The present invention provides a dense-phase conveying tank structure, including a tank body and a connecting pipe. The lower end of the tank body is clamped with the connecting pipe. An isolation barrel is slidably fitted in the tank body. The isolation barrel is provided with a plurality of cavities. A partition plate is arranged in the cavity. The partition plate is spiral. A limiting column is slidably fitted at the center of the isolation barrel. The connecting pipe is respectively communicated with a first conveying pipe and an installation pipe. The first conveying pipe is communicated with the discharge end. The inner wall of the installation pipe is slidably fitted with the limiting column. The lower end of the installation pipe is communicated with a second conveying pipe. The top end of the second conveying pipe is connected with a three-way pipe. The other two ends of the three-way pipe are respectively communicated with the tank body and a pressure device.

[0008] Furthermore, a pressure bin is provided at the lower end of the installation tube, and the pressure bin is connected to the pressure device through a second conveying pipe. A limit valve is provided at the upper end of the pressure bin, and the limit valve is in contact with the lower end surface of the limit column, and the limit valve is provided with an air vent. By providing the pressure bin, the air pressure in the installation tube can be controlled, and the limit column can be controlled to float up and down by the air pressure in the installation tube. The up and down floating of the limit column blocks or releases the isolation barrel, thereby realizing the opening and closing of the raw materials inside the tank body. The limit valve is then provided, so that the descending position of the limit column can be controlled, and when the limit column descends, the upper end of the limit column is just at the same level as the bottom end of the first conveying pipe, so that the raw materials in the tank body are sent to the outside through the first conveying pipe, that is, the discharge at the discharge end is realized.

[0009] Furthermore, the isolation barrel is divided into multiple cavities by multiple concentric barrels, and the partition is fixedly connected to the concentric barrels; by setting up the concentric barrels, the raw materials in each cavity are stored separately, which effectively reduces the phenomenon of raw material agglomeration, and makes the raw materials in each cavity small enough, so that the raw materials can be driven to rotate by the partition, thereby further reducing the phenomenon of raw material agglomeration and effectively improving the efficiency of dense phase conveying.

[0010] Furthermore, the plurality of drums are fixedly connected by a first connecting block, and a discharge port is provided at the lower end of the drum, and the discharge port cooperates with a limiting column; by providing the first connecting block, the plurality of drums become a whole, and when one of the drums rotates, the isolation barrel starts to rotate as a whole, so that the discharge of the isolation barrel is in a rotating state, thereby reducing the agglomeration of raw materials and effectively improving the efficiency of dense phase conveying.

[0011] Furthermore, a second limit block is provided at the upper end of the outer wall of the drum, and the second limit block is slidably matched with the inner wall of the tank body; by providing the second limit block, the isolation barrel will not separate from the tank body when it rotates, and the rotation of the isolation barrel will also remove the raw materials remaining on the inner wall of the tank body, effectively avoiding the agglomeration of the raw materials in the tank body and effectively improving the efficiency of dense phase conveying.

[0012] Furthermore, a first limiting groove is provided on the inner wall of the tank body, a roller is provided in the first limiting groove, and a slip ring is slidably fitted on the upper end surface of the roller; by providing the first limiting groove, the roller and the slip ring, the sliding of the slip ring is faster and more stable, and the roller reduces the wear of the slip ring, thereby further preventing the raw materials in the tank body from being contaminated, and effectively achieving a better dense phase conveying effect.

[0013] Further, the inner wall of the slip ring is fixedly connected to the second limiting block; by setting the slip ring to be fixedly connected to the second limiting block, when the isolation barrel rotates, the slip ring cooperates with the roller, making it more convenient for the isolation barrel to rotate, and the rotation of the isolation barrel will not generate large metal debris, thus preventing the raw materials in the tank from being contaminated and effectively improving the dense-phase conveying effect.

[0014] Further, a second connecting block is provided at the lower end of the tank body. A connecting pipe is slidably fitted inside the second connecting block, and fixing holes are provided on the side wall and the lower end of the second connecting block; by providing the second connecting block, the fixed connection between the connecting pipe and the tank body is realized, and by providing the fixing holes, the connection of the connecting pipe is made more stable.

[0015] Further, the fixing hole is fixedly connected to the connecting pipe by a thread. A first limiting block is provided on the outer wall of the connecting pipe. The first limiting block is the same size as the second connecting block, and the first limiting block is provided with a mating hole communicating with the fixing hole; by providing the first limiting block, the connection of the connecting pipe is made more stable, and the first limiting block limits the connection length of the connecting pipe, so that the raw materials in the isolation barrel will not be blocked, and thus the dense-phase conveying is made more stable.

[0016] Further, a valve is provided in the middle section of the tee pipe, and the valve controls the air pressure connection of the second delivery pipe; by providing the valve, the air pressure in the air pressure chamber can be controlled by the valve, so that the limiting column can float up and down through the air pressure control in the installation pipe. The up and down floating of the limiting column blocks or releases the isolation barrel, thereby realizing the opening and closing of the raw materials inside the tank body.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] By providing a limiting column controlled by a pneumatic device, the present device realizes the function of the valve, greatly reducing the time for opening and closing the valve during operation and effectively improving the efficiency of dense-phase conveying. By providing a rotatable isolation barrel, the raw materials are discharged by rotation, effectively reducing the phenomenon of raw material caking and effectively improving the efficiency of dense-phase conveying.

It is only for the convenience of simplifying the description of the present invention, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.

[0030] It will be understood that the term "a" should be construed as "at least one" or "one or more". That is, in one embodiment, the number of an element may be one, while in other embodiments, the number of the element may be more than one. The term "a" should not be construed as a limitation on the number.

[0031] The present invention provides a dense-phase conveying tank body structure. Referring to Figures 1-6 , it includes a tank body 1 and a connecting pipe 2. Preferably, both the tank body 1 and the connecting pipe 2 are made of metal, and both are aluminum alloy. The aluminum alloy can effectively prevent rusting inside the tank body 1 and the connecting pipe 2, thereby ensuring that the raw materials are not contaminated. The lower end of the tank body 1 is clamped with the connecting pipe 2. A separation barrel 3 is slidably fitted inside the tank body 1. Preferably, the material of the separation barrel 3 is the same as that of the tank body 1, thereby avoiding rusting. The separation barrel 3 is provided with a plurality of cavities 4. Preferably, the inner wall of the cavity 4 is provided with protrusions, so that when the raw materials in the separation barrel 3 descend, they are further disrupted, thereby further reducing the risk of raw material caking. A partition plate 5 is arranged inside the cavity 4. The partition plate 5 is spiral. Through the spiral partition plate 5, when the air pressure inside the tank body 1 increases and the raw materials inside the separation barrel 3 start to leak out, due to the downward pressure of the raw materials on the partition plate 5, the separation barrel 3 starts to rotate, and then the raw materials are discharged by rotation, thereby further preventing the raw materials from caking and effectively reducing the risk of blockage of the dense-phase conveying pipeline. A limiting column 6 is slidably fitted at the center of the separation barrel 3. The connecting pipe 2 is respectively communicated with a first conveying pipe 7 and an installation pipe 8. The first conveying pipe 7 is communicated with the discharge end. The inner wall of the installation pipe 8 is slidably fitted with the limiting column 6. The limiting column 6 can float up and down, thereby realizing the opening and closing of the connecting pipe 2, and further realizing the function of the discharge valve. The lower end of the installation pipe 8 is communicated with a second conveying pipe 9. The top end of the second conveying pipe 9 is connected with a three-way pipe 10. The other two ends of the three-way pipe 10 are respectively communicated with the tank body 1 and a pneumatic device.

[0032] Among them, referring to Figures 1-2 , an air pressure chamber 11 is arranged at the lower end of the installation pipe 8. The air pressure chamber 11 is communicated with the pneumatic device through the second conveying pipe 9. A limiting valve 21 is arranged at the upper end of the air pressure chamber 11. The limiting valve 21 is in contact with the lower end surface of the limiting column 6. The limiting valve 21 is provided with a ventilation hole 22. By arranging the air pressure chamber 11, the air pressure inside the installation pipe 8 can be controlled, so that the limiting column 6 can float up and down through the air pressure control inside the installation pipe 8. The up and down floating of the limiting column 6 blocks or releases the separation barrel 3, thereby realizing the opening and closing of the raw materials inside the tank body 1. By further arranging the limiting valve 21, the descending position of the limiting column 6 can be controlled, so that when the limiting column 6 descends, the upper end of the limiting column 6 is just at the same horizontal plane as the bottom end of the first conveying pipe 7, and then the raw materials inside the tank body 1 are sent to the outside through the first conveying pipe 7, that is, the discharge at the discharge end is realized.

[0033] Among them, referring to Figures 1-2, the isolation barrel 3 is divided into multiple cavities 4 by multiple concentric barrels 13, and the partition plate 5 is fixedly connected to the concentric barrels 13; by setting the concentric barrels 13, the raw materials in each cavity 4 are stored separately, effectively reducing the phenomenon of raw material caking, and making the raw materials in each cavity 4 small enough, so that the raw materials can be driven by the partition plate 5 to rotate, further reducing the phenomenon of raw material caking and effectively improving the efficiency of dense-phase conveying.

[0034] Among them, referring to Figures 1-2 , multiple barrels 13 are fixedly connected by the first connecting block 14, and a discharge port 12 is arranged at the lower end of the barrel 13, and the discharge port 12 cooperates with the limit post 6; by setting the first connecting block 14, multiple barrels 13 become an integral body. When one of the barrels 13 rotates, the isolation barrel 3 as a whole starts to rotate, so that the discharge of the isolation barrel 13 is in a rotating state, that is, the phenomenon of raw material caking is reduced, and the efficiency of dense-phase conveying is effectively improved.

[0035] Among them, referring to Figures 1-6 , a second limit block 15 is arranged at the upper end of the outer wall of the barrel 13, and the second limit block 15 is slidably matched with the inner wall of the tank body 1; by setting the second limit block 15, when the isolation barrel 3 rotates, the isolation barrel 3 will not break away from the tank body 1, and the rotation of the isolation barrel 3 will also cause the raw materials remaining on the inner wall of the tank body 1 to be removed, effectively avoiding the caking of the raw materials in the tank body 1 and effectively improving the efficiency of dense-phase conveying. A first limit groove 17 is arranged on the inner wall of the tank body 1, a roller 18 is arranged in the first limit groove 17, and a sliding ring 19 is slidably matched with the upper end surface of the roller 18; by setting the first limit groove 17 and the roller 18 and the sliding ring 19, the sliding of the sliding ring 19 is faster and more stable, and the roller 18 reduces the wear of the sliding ring 19, further avoiding the pollution of the raw materials in the tank body 1, effectively making the dense-phase conveying effect better. The inner wall of the sliding ring 19 is fixedly connected to the second limit block 15; by setting the sliding ring 19 and the second limit block 15 to be fixedly connected, when the isolation barrel 3 rotates, the sliding ring 19 cooperates with the roller 18, making the rotation of the isolation barrel 3 more convenient, and the rotation of the isolation barrel 3 will not generate large metal debris, thus avoiding the pollution of the raw materials in the tank body 1 and effectively making the dense-phase conveying effect better.

[0036] Among them, referring to Figures 1-4 , a second connecting block 20 is arranged at the lower end of the tank body 1, a connecting pipe 2 is slidably matched with the inner wall of the second connecting block 20, and fixing holes 23 are arranged on the side wall and the lower end of the second connecting block 20; by setting the second connecting block 20, the connection of the connecting pipe 2 and the tank body 1 is realized, and by setting the fixing holes 23, the connection of the connecting pipe 2 is made more stable.

[0037] Among them, referring to Figures 1-4, the fixing hole 23 is fixedly connected to the connecting pipe 2 by threads. The outer wall of the connecting pipe 2 is provided with a first limiting block 24. The first limiting block 24 is the same size as the second connecting block 20. The first limiting block 24 is provided with a matching hole 25 communicating with the fixing hole 23. By setting the first limiting block 24, the connection of the connecting pipe 2 is made more stable. And the first limiting block 24 limits the connection length of the connecting pipe 2, so that the raw materials in the isolation barrel 3 will not be blocked, and then the dense-phase conveying is made more stable.

[0038] Among them, referring to Figure 1 , a valve 16 is provided in the middle section of the tee pipe 10. The valve 16 controls the air pressure connection of the second conveying pipe 9. By setting the valve 16, the air pressure in the air pressure chamber 11 can be controlled by the valve 16. Furthermore, the limiting column 6 can float up and down through the air pressure control in the installation pipe 8. The up and down floating of the limiting column 6 causes the isolation barrel 3 to be blocked or released, and then the opening and closing of the raw materials inside the tank body 1 are realized.

[0039] Working principle: When the device works, first start and turn on the air pressure device, and at the same time toggle the valve 16 so that the air pressure device pressurizes the air pressure chamber 11. When the air pressure chamber 11 is pressurized, the limiting column 6 can float up through the air pressure control in the installation pipe 8. The upward floating of the limiting column 6 causes the isolation barrel 3 to be blocked, and then the closing of the raw materials inside the tank body 1 is realized. Then close the valve 16 so that the limiting column 6 remains in a fixed position. Then turn off the air pressure device, and then inject the raw materials into the tank body 1. When the raw materials reach the requirements, stop injecting the raw materials, and then turn off the air pressure device. And at the same time, open the valve 16 so that the air pressure chamber 11 is depressurized. By setting the limiting valve 21, the position where the limiting column 6 descends can be controlled. Furthermore, when the limiting column 6 descends, the upper end of the limiting column 6 is just at the same horizontal plane as the bottom end of the first conveying pipe 7. Then the raw materials in the tank body 1 are sent to the outside through the first conveying pipe 7, that is, the discharging at the discharging end is realized. The above actions are repeated to realize the dense-phase conveying. When the raw materials are discharged by air pressure, by setting the concentric circle barrel 13, the raw materials in each cavity 4 are stored separately, effectively reducing the phenomenon of raw material caking. And because of the downward pressure of the raw materials on the partition plate 5, the isolation barrel 3 starts to rotate, and then the raw materials are discharged by rotation. By setting the first connecting block 14, multiple round barrels 13 are integrated into a whole. When one of the round barrels 13 rotates, the isolation barrel 3 as a whole starts to rotate, and then the discharging of the isolation barrel 13 is in a rotating state, that is, the phenomenon of raw material caking is reduced, and the efficiency of dense-phase conveying is effectively improved. The device realizes the effect of the valve by setting the limiting column 6 controlled by the air pressure device, greatly reducing the time for opening and closing the valve during operation, effectively improving the efficiency of dense-phase conveying. By setting the rotatable isolation barrel 6, the raw materials are discharged by rotation, effectively reducing the phenomenon of raw material caking and effectively improving the efficiency of dense-phase conveying.

The object of the present invention has been fully and effectively achieved.
