[0003] Once the heterogeneous fluid transportation is interrupted, it is necessary to disassemble the blocked section for dredging, which not only affects the continuity of production, but also increases the labor cost and reduces the transportation efficiency of the heterogeneous fluid.

Along the air blowing direction of the air flow, the cross-sectional area of the air flow passage of the air blowing pipe member gradually decreases, so as to blow out the material in the second channel section when the material in the first channel section falls into the second channel section.

[0010] Further, along the air blowing-in direction of the air flow, the cross-sectional area of the air flow passage of the extended channel section gradually increases; the air flow in the air blowing assembly is blown into the second channel section through the extended channel section.

[0011] Further, the second channel section includes: a connecting channel section, the first end of which is communicated with the first channel section; a blowing-out channel section, the second end of which is communicated with the blowing-out channel section.

[0028] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0029] Please refer to Figures 1 to 6 , the present invention provides a conveying device, including: a first reaction kettle 1; a second reaction kettle 2, communicating with the first reaction kettle 1; a transition component 3, arranged below the first reaction kettle 1, the transition component 3 includes a transition channel 30, both ends of the transition channel 30 are respectively communicated with the first reaction kettle 1 and the second reaction kettle 2, and a vent port 301 is further arranged on the transition channel 30; a blowing component 4, communicating with the vent port 301 and blowing air flow into the transition channel 30, and blowing the materials in the transition channel 30 in the direction of the second reaction kettle 2 through the blowing component 4.

[0030] According to the conveying device provided by the present invention, it includes a first reaction kettle 1, a second reaction kettle 2, a transition assembly 3 and a blowing assembly 4. The first reaction kettle 1 is communicated with the second reaction kettle 2. After the materials react in the first reaction kettle 1, they are transferred to the second reaction kettle 2 for continuous reaction. The transition assembly 3 is arranged below the first reaction kettle 1. The transition assembly 3 includes a transition channel 30. The two ends of the transition channel 30 are respectively communicated with the first reaction kettle 1 and the second reaction kettle 2. An air vent 301 is also arranged on the transition channel 30. The blowing assembly 4 is communicated with the air vent 301 and blows air into the transition channel 30, and blows the materials in the transition channel 30 towards the direction of the second reaction kettle 2. During actual use, since the volumes of both the first reaction kettle 1 and the second reaction kettle 2 are relatively large, the first reaction kettle 1 and the second reaction kettle 2 are usually arranged side by side and communicated through pipelines. By arranging the transition assembly 3 below the first reaction kettle 1, when the materials in the first reaction kettle 1 fall into the transition channel 30 under the action of gravity, the blowing assembly 4 is used to blow air into the transition channel 30 to provide power for the flow of the materials and prevent the materials from settling at the bottom of the transition channel 30.

[0031] Specifically, the transition channel 30 includes: a first channel section 31, which is communicated with the first reaction kettle 1 and extends in the vertical direction; a second channel section 32, which is respectively communicated with the first channel section 31 and the second reaction kettle 2, and the second channel section extends in the horizontal direction. At least part of the air vent 301 is arranged on the second channel section 32. Among them, the second channel section 32 has a discharge port, and the air vent 301 is arranged opposite to the discharge port. In this way, the air flow in the air vent 301 blows the materials along the extension direction of the second channel section 32, and during the process of the materials falling from the first channel section 31 to the second channel section 32, it avoids the materials from depositing at the bottom of the second channel section 32.

[0032] During specific implementation, along the falling direction of the materials, the cross-sectional area of the material flow section of the first channel section 31 gradually increases. This is to reduce the flow rate of the materials so that the materials can be more easily blown; and / or, along the blowing direction of the materials, the cross-sectional area of the material flow section of the second channel section 32 gradually decreases. Such a setting is to increase the flow rate during the process of the materials being blown out, so that the materials can be transported to the second reaction kettle 2 more quickly.

[0033] Among them, the discharge port of the second channel section 32 is communicated with the second reaction kettle 2 through a material conveying pipeline 6.

[0034] In the first embodiment provided by the present invention, as Figure 2As shown, the transition channel 30 further includes: an extending channel section 33, which is in communication with the ventilation port 301, and the extending direction of the extending channel section 33 is the same as that of the second channel section 32; at least a part of the blowing assembly 4 is in communication with the extending channel section 33. Among them, the extending channel section 33, the first channel section 31 and the second channel section 32 form a tee structure. When the material falls from the first channel section 31 into the second channel section 32, the air flow blows out from the extending channel section 33.

[0035] Further, the blowing assembly 4 includes: a blowing pipe member 40, at least a part of the blowing pipe member 40 is arranged in the extending channel section 33, and along the blowing direction of the air flow, the cross-sectional area of the air flow passage of the blowing pipe member 40 gradually decreases, so as to blow out the material from the second channel section 32 when the material in the first channel section 31 falls into the second channel section 32. Such a setting can directly sleeved the extending channel section 33 on the blowing pipe member 40, playing a certain protective role for the blowing pipe member 40. Gradually reducing the cross-sectional area of the air flow passage of the blowing pipe member 40 can increase the flow velocity of the air flow during the blowing process of the air flow, and further increase the power exerted by the air flow on the material.

[0036] In the second embodiment provided by the present invention, as Figure 3 shown, along the blowing-in direction of the air flow, the cross-sectional area of the air flow passage of the extending channel section 33 gradually increases; the air flow in the blowing assembly 4 is blown into the second channel section 32 through the extending channel section 33. In this embodiment, the blowing assembly 4 includes a blowing pipe member 40, and the blowing pipe member 40 is in communication with the air inlet of the extending channel section 33. After the blowing pipe member 40 blows the air flow into the extending channel section 33, under the action of the change of the cross-sectional area of the air flow passage in the extending channel section 33, the flow velocity of the air flow decreases, but the air flow rate gradually increases, and thus the pressure gradually increases, which can push the material out of the second channel section 32.

[0037] In the third embodiment provided by the present invention, as Figure 4 shown, the second channel section 32 includes: a connecting channel section 321, the first end of the connecting channel section 321 is in communication with the first channel section 31; a blowing-out channel section 322, the second end of the connecting channel section 321 is in communication with the blowing-out channel section 322, the connecting channel section 321 extends along an arc track, the blowing-out channel section 322 extends along the horizontal direction, and the blowing-out channel section 322 is in communication with the second reaction kettle 2. Since the connecting channel section 321 extends along an arc track, when the material falls from the first channel section 31, it falls into the blowing-out channel section 322 under the guiding action of the arc inner wall surface of the connecting channel section 321.

[0038] Further, the ventilation opening 301 is provided on the blowing channel section 322 and is located below the outlet end of the connecting channel section 321. The blowing assembly 4 includes: a blowing pipe member 40, and the air outlet of the blowing pipe member 40 is communicated with the ventilation opening 301. By arranging the ventilation opening 301 below the outlet end of the connecting channel section 321 and on the blowing channel section 322, when the material falls out from the connecting channel section 321, the air flow is blown out from the ventilation opening 301 below. Under the action of the air flow, the material is prevented from directly falling on the bottom of the blowing channel section 322.

[0039] In the fourth embodiment provided by the present invention, which is different from the third embodiment, the ventilation opening 301 is provided on the connecting channel section 321. The blowing assembly 4 includes: a blowing pipe member 40, and at least a part of the blowing pipe member 40 extends into the blowing channel section 322 through the ventilation opening 301. Wherein, multiple groups of blowing hole groups 401 are arranged on the pipe wall of the blowing pipe member 40, and the multiple groups of blowing hole groups 401 are arranged at intervals along the circumferential direction of the blowing pipe member 40. Each group of blowing hole groups 401 includes multiple blowing holes, and the multiple blowing holes are arranged at intervals along the axial direction of the blowing pipe member 40. In this way, when the air flow flows in the blowing pipe member 40, the air flow is blown out in a divergent manner towards the inner wall surface of the blowing channel section 322 through each blowing hole in each group, and the material rolls under the action of the air flow, avoiding deposition.

[0040] Wherein, there is an included angle between the extending direction of the blowing hole and the axis direction of the blowing pipe member 40, and the center line of the blowing hole is inclined towards the outflow direction of the air flow in the blowing pipe member 40. In this way, when the air flow is blown out from the blowing hole, the included angle with the flowing direction of the material becomes smaller, improving the efficiency of blowing out the material.

[0041] Preferably, as Figure 4 and Figure 5 shown, the blowing pipe member 40 extends in the horizontal direction, or the blowing pipe member 40 extends along a spiral track. Such an arrangement is to make the material roll when the air flow is blown out, and can also blow out the material deposited on the inner wall surface of the blowing channel section 322 together.

[0042] In this application, as Figure 1 shown, the blowing assembly 4 further includes: a first air supply pipeline 41, communicated with the transition channel 30; a second air supply pipeline 42, communicated with the feed inlet of the first reaction kettle 1; a third air supply pipeline 43, communicated with the feed inlet of the second reaction kettle 2. Such an arrangement utilizes the air flow in the second air supply pipeline 42 to provide pressure to the material in the first reaction kettle 1, which is beneficial to the discharge of the material from the first reaction kettle 1. Similarly, the air flow in the third air supply pipeline 43 is utilized to provide pressure to the feed inlet of the second reaction kettle 2, which is beneficial to the discharge of the material from the second reaction kettle 2.

[0043] Furthermore, the air inlet of the second air supply pipeline 42 is communicated with the air inlet end of the first air supply pipeline 41. The blowing assembly 4 further includes: a boosting component 44 disposed on the first air supply pipeline 41; a circulation branch 45, one end of the circulation branch 45 is communicated with the gas outlet end of the boosting component 44, and the other end of the circulation branch 45 is communicated with the gas inlet end of the boosting component 44. Preferably, the boosting component 44 is a gas compressor. During use, after the air flow in the first air supply pipeline 41 is pressurized by the boosting component 44, if further pressurization is required, the air flow uses the circulation branch 45 to flow to the gas inlet end of the boosting component 44 and mixes with the air flow just entering the first air supply pipeline 41 to continue pressurization to reach a predetermined air flow pressure value. A fourth pressure control valve 450, i.e., PV4 shown in the figure, is disposed on the circulation branch 45 to control the gas pressure in the circulation branch 45.

[0044] During the specific implementation process, a first pressure detection component 410 and a first pressure control valve 411 are disposed on the first air supply pipeline 41 for detecting the pressure in the first air supply pipeline 41 and adjusting the pressure value in the first air supply pipeline 41; a second stop valve 412 is disposed at the gas inlet end of the boosting component 44, and a third stop valve 413 is disposed at the gas outlet end of the boosting component 44 to achieve the purpose of pressure regulation and throttling. Among them, the first pressure detection component 410 is a first pressure sensor, PT3 is the first pressure sensor in the figure, PV3 is the first pressure control valve, HV2 is the second stop valve, and HV3 is the third stop valve.

[0045] A second pressure detection component 420 and a second pressure control valve 421 are disposed on the second air supply pipeline 42. The pressure value of the air flow in the second air supply pipeline 42 is detected by the second pressure detection component 420, and the pressure in the second air supply pipeline 42 is adjusted by the second pressure control valve 421. Among them, the second pressure detection component 420 is a second pressure sensor, PT1 is the second pressure sensor in the figure, and PV1 is the second pressure control valve.

[0046] A third pressure detection component 430 and a first shut-off valve 432 are provided on a third gas supply pipeline 43. The pressure inside the third gas supply pipeline 43 is detected by the third pressure detection component 430, and the gas pressure inside the third gas supply pipeline 43 is adjusted by the first shut-off valve 432. Among them, the blowing assembly 4 further includes a main gas supply line. The first gas supply pipeline 41, the second gas supply pipeline 42, and the third gas supply pipeline 43 are all connected to the main gas supply line. A third pressure control valve 431 is provided on the main gas supply line. The third pressure control valve 431 is located between the air inlet of the second gas supply pipeline 42 and the air inlet of the third gas supply pipeline 43. The intake air flow rate inside the third gas supply pipeline 43 and / or the intake air flow rate inside the first gas supply pipeline 41 is adjusted by the third pressure control valve 431. Among them, the third pressure detection component 430 is a third pressure sensor. In the figure, PT2 is the third pressure sensor, PV2 is the third pressure control valve, and HV1 is the first shut-off valve; FT1 is a flow sensor, and FV1 is a flow control valve. The flow sensor and the flow control valve are both provided on the discharging channel of the first reaction kettle 1. The discharging amount of the material inside the first reaction kettle 1 is controlled by the flow sensor and the flow control valve. According to the reflected discharging amount, the pressure of the conveying air flow of the boosting component 44 is controlled proportionally, providing a basis for the pressure regulation of the entire pipeline system and ensuring the stable conveying of the material. Among them, a filter 5 is provided at the intake end of the third gas supply pipeline 43 to filter the air flow inside the third gas supply pipeline 43.

[0047] Preferably, the gas pressure inside the third gas supply pipeline 43 is controlled between 0.2 MPa and 0.4 MPa, and the gas pressure inside the second gas supply pipeline 42 is controlled between 0.2 MPa and 0.4 MPa; the gas pressure at the inlet end of the boosting component 44 is between 0.2 MPa and 0.4 MPa.

[0048] In this application, the air flow is an inert gas, which can avoid chemical reactions with the material. In the entire device, the first gas supply pipeline 41, the second gas supply pipeline 42, and the third gas supply pipeline 43 are used to realize air flow circulation, effectively reducing energy consumption and improving the high-efficiency utilization of the recycled gas. Through the cooperation of the blowing pipe member 40 and the transition channel 30, the problems of maintenance or replacement caused by the settlement of the solid dispersed phase during the transportation of the heterogeneous fluid material are effectively reduced, and the maintenance intensity and cost of the device are reduced.

[0049] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0050] The conveying device provided by the present invention includes a first reaction kettle 1, a second reaction kettle 2, a transition assembly 3 and a blowing assembly 4. The first reaction kettle 1 is communicated with the second reaction kettle 2. After the material reacts in the first reaction kettle 1, it is transferred to the second reaction kettle 2 for continuous reaction. The transition assembly 3 is arranged below the first reaction kettle 1. The transition assembly 3 includes a transition channel 30. Both ends of the transition channel 30 are respectively communicated with the first reaction kettle 1 and the second reaction kettle 2. An air vent 301 is also arranged on the transition channel 30. The blowing assembly 4 is communicated with the air vent 301 and blows air into the transition channel 30, and the material in the transition channel 30 is blown towards the direction of the second reaction kettle 2 through the blowing assembly 4. During the actual use process, since the volumes of both the first reaction kettle 1 and the second reaction kettle 2 are relatively large, the first reaction kettle 1 and the second reaction kettle 2 are usually arranged side by side and communicated through pipelines. By arranging the transition assembly 3 below the first reaction kettle 1, when the material in the first reaction kettle 1 falls into the transition channel 30 under the action of gravity, the blowing assembly 4 is used to blow air into the transition channel 30 to provide power for the flow of the material and prevent the material from settling at the bottom of the transition channel 30.
