Description
INTELLIGENT MODULAR PNEUMATIC CONVEYING DEVICE
This application relates to the field of fluid transport, in particular to an intelligent modular pneumatic conveying device.
During transport of fluids through the conveying pipeline, there are sometimes particles of relatively large weight in the fluids, and the friction between these particles is also relatively large, so that the resistance between the fluids and the conveying pipeline is correspondingly increased.
When there is a large number of fluids, the method of transferring the fluids through a transfer pump or the like in the prior art obviously cannot meet the actual production demand. Specifically, because the transfer pump can provide limited conveying force, it cannot efficiently convey a large number of fluids, and based on the specific structure of the transfer pump, during the fluid conveying process, it is very likely that the fluids or fine particles in the fluids will enter the transfer pump along the conveying pipeline, thereby causing damage to the transfer pump, which is not conducive to the smooth operation of the fluid conveying process.
In addition, the end of the conveying pipeline is generally connected to a filtering device for separating liquid and solid in the fluids. In order to improve the solid-liquid separation efficiency of the fluids, multiple filtering devices are generally provided, and the multiple filtering devices are likely to be located at different positions based on different equipment layout requirements. In this case, most of the existing conveying equipment cannot achieve the effect of conveying the fluids in multiple directions, and therefore cannot meet the requirement of reprocessing the fluids by the filtering devices provided at multiple positions.
In view of this, the fluid conveying device in the prior art needs to be further improved.
The present invention provides an intelligent modular pneumatic conveying device to solve at least one of the above technical problems.
To achieve the above objective, the present invention provides an intelligent modular pneumatic conveying device, including an air compressor, a thickener and a silo pump; the silo pump is provided with an air inlet, an air outlet, and a plurality of material inlets and outlets; the air inlet is connected to the air compressor, the air outlet is connected to external equipment, and the material inlets and outlets are separately connected to the external equipment and the thickener; the thickener is configured to convey materials to the silo pump, and the air compressor is configured to deliver compressed air generated thereby to the silo pump through the air inlet; when the materials enter the silo pump from at least one of the material inlets and outlets, the materials can be pushed to any of the material inlets and outlets under the action of the compressed air and conveyed to the external equipment.
In this application, the air compressor and the air inlet and air outlet of the silo pump are provided so that the air compressor can deliver the compressed air generated thereby to the silo pump through the air inlet, and the materials are conveyed under the action of the compressed air to the external equipment. In this application, pumping high-pressure air into the silo pump through the air compressor can provide the pneumatic conveying device with a larger conveying force, so as to realize the high-efficiency transmission of a large amount of ore pulp, thereby improving the conveying efficiency of ore pulp. In this application, a plurality of material inlets and outlets are provided in the silo pump, and when the materials enter the silo pump from at least one of the material inlets and outlets, the materials can be pushed to any of the material inlets and outlets under the action of the compressed air, so as to realize that the materials enter the silo pump through the plurality of material inlets and outlets, and can flow out from the plurality of material inlets and outlets, thereby enabling multiple directional conveyance of the materials and filtering of the materials by filtering devices provided at multiple positions.

As shown in Figs. 1-5, the present invention provides an intelligent modular pneumatic conveying device, including an air compressor 1, a thickener 3 and a silo pump 4; the silo pump 4 is provided with an air inlet 402, an air outlet 403, and a plurality of material inlets and outlets 401; the air inlet 402 is connected to the air compressor 1; the air outlet 403 is connected to external equipment 5, and the material inlets and outlets 401 are separately connected to the external equipment 5 and the thickener 3; the thickener 3 is configured to convey materials to the silo pump 4; the air compressor 1 is configured to deliver compressed air generated thereby to the silo pump 4 through the air inlet 402; when the materials enter the silo pump 4 from at least one of the material inlets and outlets 401, the materials can be pushed under the action of the compressed air to any of the material inlets and outlets 401 and conveyed to the external equipment 5.
In the actual use of the pneumatic conveying device, the thickener 3 1s connected to a slurry pump (not shown), under the action of the slurry pump, the thickener 3 conveys materials from any of the material inlets and outlets 401 to the silo pump 4; under the action of the air compressor 1, compressed air is delivered to the silo pump 4 from the air inlet 402; under the action of the compressed air, the materials in the silo pump 4 can be pushed to the external equipment 5 by any of the material inlets and outlets 401 for filtering.
From the above description, it can be seen that the present invention achieves the following technical effects.
In this application, the air compressor 1 and the air inlet 402 and air outlet 403 of the silo pump 4 are provided so that the air compressor 1 can deliver the compressed air generated thereby to the silo pump 4 through the air inlet 402, and the materials are pushed under the action of the compressed air to the external equipment 5 for filtering. In this application, pumping high-pressure air into the silo pump 4 through the air compressor 1 can provide the pneumatic conveying device with a larger conveying force, so as to realize the high-efficiency transmission of a large amount of ore pulp, thereby improving the conveying efficiency of ore pulp. In this application, a plurality of material inlets and outlets 401 are provided in the silo pump 4, when the materials enter the silo pump 4 from at least one of the material inlets and outlets 401, the materials can be pushed to any of the material inlets and outlets 401 under the action of the compressed air, so as to realize that the materials enter the silo pump 4 through the plurality of material inlets and outlets 401, and can flow out from the plurality of material inlets and outlets 401, thereby enabling multiple directional conveyance of the materials and filtering of the materials by the external equipment provided at multiple positions.
In one embodiment, the material inlets and outlets 401 include a feed port and a discharge port, and one of the feed port and the discharge port is provided in the top of the silo pump 4, the other of the feed port and the discharge port is provided in the bottom of the silo pump 4, so that the pneumatic conveying device has a first conveying position for upper feeding and lower discharging, as shown in Fig. 2, where the solid line represents feeding and the dashed line represents discharging; and has a second conveying position for lower feeding and upper discharging, as shown in Fig. 3, where the solid line represents feeding and the dashed line represents discharging. Through the arrangement of the first conveying position and the second conveying position, the pneumatic conveying device realizes the material conveying state of upper feeding and lower discharging and the material conveying state of lower feeding and upper discharging. In specific implementation, the silo pump 4 can also be provided with a radar level gauge (not shown) to control the amount of the materials fed and discharged; of course, those skilled in the art can understand that the silo pump can also be provided with a safety valve (not shown) to monitor the pressure in the silo pump 4 in real time. When the pressure in the silo pump 4 is too high, the safety valve can relieve the pressure of the silo pump 4 in time to prevent the silo pump 4 from exploding due to excessive pressure, thereby improving the safety and stability of the operation process of the silo pump 4.
In one embodiment, a plurality of silo pumps 4 are provided; the pneumatic conveying device further includes a first material conveying main pipe 6 and a second material conveying main pipe 7 that are provided at the upper end and the lower end of the plurality of silo pumps 4, respectively, and first ends of the first material conveying main pipe 6 and the second material conveying main pipe 7 are both connected to the thickener 3 and second ends thereof are both connected to the external equipment 5; the pneumatic conveying device further includes a plurality of first material conveying branch pipes 601 and a plurality of second material conveying branch pipes 701, and the first material conveying branch pipes 601 are separately connected to the material inlets and outlets 401 and the first material conveying main pipe 6; the second material conveying branch pipes 701 are separately connected to the material inlets and outlets 401 and the second material conveying main pipe 7. By providing a plurality of silo pumps 4, mass conveyance of materials can be achieved, and control on the pneumatic conveying device to achieve a plurality of feeding and discharging ways of materials is facilitated by the arrangement of the first material conveying main pipe 6, the second material conveying main pipe 7, the first material conveying branch pipes 601 and the second material conveying branch pipes 701. Of course, those skilled in the art can understand that control valves can be provided at the first material conveying branch pipes 601 and the second material conveying branch pipes 701, and the radar level gauges and the control valves cooperate with each other; when the radar level gauge detects the level of the materials in the silo pump 4 is higher than the preset value, the control valve that controls the materials entering the silo pump 4 is closed, and the thickener 3 stops inputting materials into the silo pump 4; when the radar level gauge detects that the level of the materials in the silo pump 4 is lower than the preset value, the control valve that controls the materials entering the silo pump 4 is opened, and the thickener 3 inputs materials into the silo pump 4. In specific implementation, it may be further preferable to make the first material conveying main pipe 6 and the second material conveying main pipe 7 inclined at an angle of 3°-5°, so that the materials can be separately conveyed to a plurality of silo pumps 4 by gravity to prevent material deposits.
In the specific operation, as shown in Fig. 1, for example, four silo pumps 4 can be provided, and the four silo pumps 4 can be labeled silo pump one, silo pump two, silo pump three, and silo pump four in turn from right to left. In specific implementation, the four silo pumps 4 can be arranged side by side, and the tops of the four silo pumps 4 are on the same plane; in addition, silo pump one, silo pump two, silo pump three and silo pump four may also be arranged in a descending manner from right to left to facilitate the conveying of materials by gravity. During the operation of the pneumatic conveying device, although a plurality of silo pumps 4 are provided, the silo pumps 4 in any quantity can be operated according to actual conditions, and the silo pumps in any quantity 4 can simultaneously achieve upper feeding and lower discharging; or, lower feeding and upper discharging; or, upper feeding and upper discharging; or lower feeding and lower discharging, etc.
During the operation of the pneumatic conveying device, other forms of feeding and discharging of materials can also be realized. When only silo pump one and silo pump two are operated, either silo pump one or silo pump two is fed and the other discharges materials. When silo pump one is fed from above, silo pump two discharges materials from above or below; or when silo pump one is fed from below, silo pump two discharges materials from above or below; or when silo pump two is fed from above, silo pump one discharges materials from below; or when silo pump two is fed from below, silo pump one discharges materials from above. Of course, those skilled in the art can understand that it is also possible to operate only silo pump one and silo pump three or only silo pump two and silo pump four or only silo pump three and silo pump four, that is, any two silo pumps in the pneumatic conveying device.
In the case where silo pump one, silo pump two and silo pump three are operated, when silo pump one is fed from above, silo pump two and silo pump three discharge materials from above or below; or, when silo pump one is fed from below, silo pump two and silo pump three can discharge materials from above or below; or, when silo pump one and silo pump two are both fed from above, silo pump three can discharge materials from above or below; or, when silo pump one and the silo pump two are both fed from below, silo pump three can discharge materials from above or below. Of course, those skilled in the art can understand that it means operating any three silo pumps in the pneumatic conveying device.
For example, when silo pump one, silo pump two, silo pump three, and silo pump four are operated, silo pump one and silo pump two are fed from above, and silo pump three and silo pump four discharge materials from below; or, silo pump one and silo pump two are fed from below, silo pump three and silo pump four discharge materials from above. Or, silo pump one and silo pump three are fed from above at the same time, silo pump two and silo pump four discharge materials from below at the same time; or silo pump one and silo pump three are fed from below at the same time, silo pump two and silo pump four discharge materials from above at the same time. Of course, those skilled in the art can understand that it means operating any four silo pumps in the pneumatic conveying device. Of course, the number of the silo pumps 4 of the pneumatic conveying device is not limited to four, and the conveying position of each silo pump 4 is not limited to the manner described herein if it is convenient for actual production.
In one embodiment, the feed port and the discharge port are both provided in the top of the silo pump 4, so that the pneumatic conveying device has a third conveying position for upper feeding and upper discharging, as show in Fig 4, where the solid line represents feeding and the dash line represents discharging; or the feed port and the discharge port are both provided in the bottom of the silo pump 4, so that the pneumatic conveying device has a fourth conveying position for lower feeding and lower discharging, as show in Fig 5, where the solid line represents feeding and the dash line represents discharging. In this application, through the arrangement of the third conveying position and the fourth conveying position, the pneumatic conveying device realizes the material conveying state of upper feeding and upper discharging and the material conveying state of lower feeding and lower discharging.
In one embodiment, the air inlet 402 and the air outlet 403 are both provided in the top of the silo pump 4, so that the pneumatic conveying device has a first air delivery position for air intake from above and air exhaust from above; or the air inlet 402 and the air outlet 403 are provided in the bottom of and in the top of the silo pump 4, respectively, so that the pneumatic conveying device has a second air delivery position for air intake from below and air exhaust from above. In this application, through the arrangement of the first air delivery position and the second air delivery position, the pneumatic conveying device realizes the air conveying state of top in and top out and the air conveying state of bottom in and top out. Since the materials have certain gravity, the materials accumulate at the lower part of the silo pump 4, if the pneumatic conveying device has a state of air exhaust from below, the materials are prone to blocking the air outlet 403 in the bottom of the silo pump 4 or blocking the air outlet branch pipe 901.

Thus, by means of the pneumatic conveying device being networked to the cloud, the opening and closing of the pneumatic delivery device can be controlled in real time, the operating conditions of the pneumatic delivery device can be observed in real time, and the feeding and discharging of materials and the delivery of compressed air for each of the silo pumps 4 can be controlled in real time according to production needs, and operations such as clearing of the silo pumps 4 and pipelines can be achieved by the mobile terminal.
In specific implementation, a silencer (not shown) is provided between the air outlet main pipe 9 and the external equipment 5. In this application, the arrangement of the silencer has a noise reduction effect on the pneumatic conveying device and reduces noise pollution.
Finally, the intelligent modular pneumatic conveying device provided by this application uses positive pressure to convey fluids in the pipeline; in the prior art, negative pressure conveying is mostly used; compared with negative pressure conveying, positive pressure conveying uses "pressure" to drive materials, while negative pressure conveying generally uses "suction" to drive fluids. In comparison, the driving force generated by positive pressure conveying is much greater than that of negative pressure conveying. In fact, compared to a negative pressure conveying system in the prior art, the pneumatic conveying device provided herein has a conveying efficiency that is tens, or even hundreds, of times higher than that of the negative pressure conveying system, and the two conveying efficiencies are in different orders of magnitude.
In addition, with regard to the adjustment of the fluid flow during the conveying process, in the prior art, hydraulic-actuated diaphragm pumps adopting the methods of oil and water are mostly used, and no matter which the method mentioned above is adopted, it is necessary to provide a corresponding diaphragm pump to control the fluid flow. In the intelligent modular pneumatic conveying device provided by this application, a diaphragm pump is eliminated, so that fluids in the pipeline can be conveyed and the fluid flow can be adjusted by compressed air and silo pumps, thereby greatly improving the conveying efficiency of fluids, and realizing precise and intelligent control of fluids.
