Description

Technical Field

[0001] The invention relates to the technical field of material conveying, and in particular to an upward-pulling silo pump system. Background Art

[0002] Pneumatic conveying is a technology that uses the energy of airflow to transport granular materials along the airflow direction in a closed pipeline. Pneumatic conveying uses the dynamic pressure and static pressure of air to suspend material particles in the airflow or form a mass and transport them along the pipeline. Pneumatic conveying is divided into dilute phase conveying and dense phase conveying. Dense phase conveying is more suitable for pipeline transportation of powder and granular materials because of its longer conveying distance and less material wear.

[0003] The conventional steps of pneumatic conveying are to introduce the materials in the raw material bin into the dense phase conveying device, and then the dense phase conveying device starts to work and pressurizes the incoming materials so that the incoming materials can be discharged under high pressure and enter the subsequent processing equipment;

[0004] However, when receiving materials from the raw material bin, the dense phase conveying device of the prior art needs to separately supply gas to the raw material bin and the dense phase conveying device. Each time the dense phase conveying device conveys, it needs to wait for the materials in the raw material bin to flow in before the dense phase conveying device is pressurized. This makes the process flow longer and the material conveying efficiency is very low.

[0005] Moreover, when transporting materials, since some materials have a certain viscosity (such as wet coal powder, wet slag and other materials), after long-term use, agglomerated impurities will form on the inner wall of the transmission tank of the dense phase conveying device. On the one hand, the presence of impurities reduces the capacity of the transmission tank. On the other hand, when the material is transported, the impurities will be shaken off by the vibration of the device during operation and fall into the transported material. Since the impurities are agglomerated, they are more likely to block the transmission pipeline during transmission, greatly affecting the transmission efficiency. In addition, the agglomerated impurities increase the difficulty of subsequent processing of the material and affect the production efficiency. Summary of the invention

[0006] In order to overcome the shortcomings of low material conveying efficiency of dense phase conveying devices in the prior art and the generation of agglomerated impurities on the inner wall of the transmission tank, the present invention provides an upward-pulling silo pump system.

DETAILED DESCRIPTION

[0032] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] Example 1

[0034] A top-lift silo pump system, such as Figure 1-11 As shown, it includes a bin body 1, a bin cover 2, a hollow connecting strip 3, a feed pipe 4, a discharge pipe 5, an upper boost pipe 7, an exhaust pipe 8 and a material level monitor 9; the bin body 1 is fixedly connected with the hollow connecting strip 3; the hollow connecting strip 3 is fixedly connected with the bin cover 2, and the bin cover 2 is provided with an air pressure monitor; the bin cover 2 is connected with the feed pipe 4; the bin cover 2 is fixedly connected with the discharge pipe 5, and the discharge pipe 5 is located in the bin body 1; the bin cover 2 is connected with the upper boost pipe 7; the bin cover 2 is connected with the exhaust pipe 8, and the exhaust pipe 8 is provided with a valve; the bin cover 2 is provided with a material level monitor 9;

[0035] It also includes a lower boost pipe 6; the bottom of the warehouse body 1 is connected to the lower boost pipe 6, and the lower boost pipe 6 is provided with a switch valve.

[0036] It also includes a hollow rotating wheel 101, leaves 102, a breaking and cleaning component, a hollow rotating ring 106 and an air valve 107; the bin body 1 is rotatably connected to the hollow rotating wheel 101, and the hollow rotating wheel 101 is rotatably connected to the bin cover 2; a plurality of leaves 102 are fixedly connected to the outer ring surface of the hollow rotating wheel 101; two breaking and cleaning components are fixedly connected to the inner ring surface of the hollow rotating wheel 101, and all the breaking and cleaning components are rotatably connected to the bin body 1 through the rotating ring; the discharge pipe 5 is rotatably connected to the hollow rotating ring 106, and each breaking and cleaning component is connected to the hollow rotating ring 106; the hollow connecting bar 3 is fixedly connected to the air valve 107, and the hollow connecting bar 3 is provided with an exhaust hole.

[0037] The scattering cleaning components on the left side of the device include an adapter 103, a hollow cleaning bar 104, and a hollow rotating sheet 105; the inner ring surface of the hollow rotating wheel 101 is connected to the adapter 103; the adapter 103 is connected to the hollow cleaning bar 104, and the hollow cleaning bar 104 is in contact with the warehouse body 1; the hollow cleaning bar 104 is connected to the hollow rotating sheet 105, and the hollow rotating sheet 105 is fixedly connected to the hollow rotating ring 106, and the hollow rotating sheet 105 is rotatably connected to the warehouse body 1 through the rotating ring.

[0038] The hollow rotating piece 105 is twisted, and the twisted hollow rotating piece 105 can break up the materials when rotating.

[0039] Before using the device, the upper boost pipe 7 is connected to the external air pump, the discharge end of the raw material bin is connected to the feed pipe 4 through the opening and closing valve, and the discharge pipe 5 is connected to the external material receiving device. After that, when the device needs to work, the opening and closing valve is opened, and the material in the raw material bin enters the inside of the transmission tank composed of the bin body 1, the bin cover 2 and the hollow connecting strip 3 from the feed pipe 4 until the height of the material accumulated at the bottom of the transmission tank exceeds the lower end opening of the discharge pipe 5;

[0040] And because the discharge pipe 5 is set long, in order to ensure the stability of the discharge pipe 5 during operation and prevent shaking, the discharge pipe 5 is connected with a hollow rotating ring 106, and the hollow rotating ring 106 is connected with a hollow rotating sheet 105, and the hollow rotating sheet 105 is rotatably connected to the warehouse body 1 through the rotating ring, so that the hollow rotating ring 106 and the hollow rotating sheet 105 play a function of stabilizing the discharge pipe 5;

[0041] After that, the external air pump starts to work, and the air is introduced into the transmission tank through the upper boost pipe 7. The pressure in the transmission tank increases to form high-pressure air. At this time, the material in the transmission tank is squeezed by the high-pressure air and enters the discharge pipe 5, so that the dense phase transmission of the material can be realized. After the work of this device is completed, the valve of the exhaust pipe 8 is opened to discharge the internal air, so that the device can carry out the subsequent work normally;

[0042] The device is provided with a material level monitor 9. When the material accumulation height in the transmission tank is lower than the lower opening of the discharge pipe 5, the opening range of the opening and closing valve is controlled to increase, so that the material can be replenished into the transmission tank in time.

[0043] However, when the material is transported in this way, both the raw material warehouse and the transmission tank of the device need to be supplied with gas separately. When the transmission tank is transporting, it must first wait for the material in the raw material warehouse to flow in, and then pressurize the transmission tank. This results in that the transport work is not carried out continuously, so the transport process is longer, resulting in low material transport efficiency.

[0044] Therefore, the bin cover 2 of the device is provided with an air pressure monitor, and the exhaust pipe 8 is connected to the raw material bin. When the material in the raw material bin enters the transmission tank composed of the bin body 1, the bin cover 2 and the hollow connecting strip 3 from the feed pipe 4, the valve of the exhaust pipe 8 is opened, so that the high-pressure air in the transmission tank can enter the raw material bin, so that the air pressure in the raw material bin and the transmission tank can be balanced, and the material can directly fall into the transmission tank normally from the feed pipe 4, so that the high-pressure air in the transmission tank will not support the material in the raw material bin, thereby causing the material in the raw material bin to be unable to be normally transmitted;

[0045] The air pressure monitor provided on the bin cover 2 monitors the air pressure in the transmission tank at all times. When the air pressure in the transmission tank becomes low and the material cannot be transported from the discharge pipe 5, the opening and closing valve connected to the feed pipe 4 is closed, and then the air pressure monitor sends a signal to control the external air pump connected to the upper boost pipe 7 to increase the output power, thereby maintaining the continuous material transportation operation of the device;

[0046] Since the materials are accumulated at the bottom of the transmission tank and can be transported out of the discharge pipe 5 only when squeezed by high-pressure air, the materials will be squeezed into blocks in actual work, which will cause the output materials to be stuck in the discharge pipe 5 during transportation, affecting the subsequent production of the materials.

[0047] Therefore, the device is provided with a lower boost pipe 6. Before the device works, the switch valve of the lower boost pipe 6 is opened, and the external pump is connected to the lower boost pipe 6. Then, while the external air pump connected to the upper boost pipe 7 is working, the external pump connected to the lower boost pipe 6 starts to work, and the air is introduced into the transmission tank from the lower boost pipe 6. The external pump connected to the lower boost pipe 6 works regularly and intermittently, and the air pressure output by the external pump when working is greater than the high-pressure air in the transmission tank. In this way, the material in the transmission tank will be impacted by the air output by the external pump and dispersed, so that the material in the prior art is avoided from being squeezed into blocks in actual work, which leads to the problem that the output material will be stuck in the discharge pipe 5 during transportation, and the subsequent production of the material will be affected on the one hand.

[0048] And because some materials are sticky, this will cause the transmission tank to form agglomerated impurities after long-term use of the device. The presence of impurities reduces the capacity of the transmission tank. On the other hand, when the material is transmitted, the impurities will be shaken off by the vibration of the device during operation and fall into the transmitted material. Since the impurities are agglomerated, they are more likely to block the transmission pipeline during transmission, greatly affecting the transmission efficiency. The agglomerated impurities increase the difficulty of subsequent material processing and affect the production efficiency.

[0049] Therefore, before the device is operated, the air valve 107 is also connected to the external air pump. When the device is transmitting, the external air pump simultaneously introduces air into the hollow connecting strip 3 through the air valve 107, and the air entering will flow out from the exhaust hole of the hollow connecting strip 3. At this time, the air in the hollow connecting strip 3 flows in the cavity in the hollow connecting strip 3, and the flowing air drives the leaf piece 102 to exert force on the hollow rotating wheel 101, so that the hollow rotating wheel 101 starts to rotate. When the hollow rotating wheel 101 rotates, it drives the connected adapter 103 and the hollow cleaning strip 104 to rotate in turn, and the hollow cleaning strip 104 drives the connected hollow rotating piece 105 to rotate, and the hollow rotating piece 105 drives the hollow rotating ring 106 to rotate around the center of the discharge pipe 5.

[0050] During the rotation process, the hollow cleaning strip 104 scrapes the inner wall of the bin body 1, so that when the device is conveying, the material stuck to the inner wall of the bin body 1 will be scraped off, and when the twisted hollow rotating piece 105 rotates, the material at the bottom of the transmission tank is stirred, thereby further breaking up the material; in this way, the transmission tank will not have the problem of forming agglomerated impurities, and the hollow rotating piece 105 further breaks up the material when rotating, making it less likely to clump.

[0051] Example 2

[0052] On the basis of Example 1, Figure 6-Figure 8 As shown,

[0053] It also includes an air inlet hole 1011 and an air jet hole 1041 ; the hollow rotating wheel 101 is provided with an air inlet hole 1011 ; and each hollow cleaning strip 104 is provided with a plurality of air jet holes 1041 .

[0054] like Figure 8As shown, when the material is accumulated to the position of the accumulation height schematic line 12, the lower boost pipe 6 will form an air mass 61 when conveying air into the transmission tank. However, since the air mass 61 needs to have a relatively large pressure, the diameter of the lower boost pipe 6 cannot be set too large, otherwise too much air will enter the transmission tank, which will cause the pressure of the device to be too high and unable to operate. However, when the diameter of the lower boost pipe 6 is small, it is impossible to fully impact the material in the transmission tank, and it can only impact and stir the middle part of the material. When the hollow rotor 105 rotates and stirs the material, it is also impossible to stir the material in all areas, and it can only stir the material in contact with the surrounding of the hollow rotor 105. Therefore, the material will have an empty stirring area 13 in actual work, and the material in the empty stirring area 13 will still be squeezed into blocks by high-pressure air.

[0055] Therefore, an air inlet 1011 is provided on the hollow rotor 101. When the external air pump is working to introduce air from the air valve 107 into the hollow connecting bar 3 to drive the hollow rotor 101 to rotate, a part of the air enters the inner cavity of the hollow rotor 101 from the air inlet 1011, and the air in the inner cavity of the hollow rotor 101 enters the adapter 103, and the adapter 103 introduces the air into the hollow cleaning bar 104. Thereafter, the air entering the hollow cleaning bar 104 will be ejected from the jet hole 1041 to impact and stir the material in the air stirring zone 13, and the hollow cleaning bar 104 rotates when performing material conveying work. During the rotation process, the hollow cleaning bar 104 can comprehensively impact and stir the material in the air stirring zone 13, thereby avoiding the problem that when conveying materials, there will be an air stirring zone 13 in actual work, and the material in the air stirring zone 13 will still be squeezed into blocks by high-pressure air.

[0056] Example 3

[0057] On the basis of Example 2, Figure 9-11 As shown,

[0058] It also includes a connecting tube 1051, a hollow elastic tube 201, a rotating pull tab 202, and a limit strip 203; each hollow rotating tab 105 is connected to the connecting tube 1051, and each connecting tube 1051 passes through the hollow rotating ring 106; the discharge tube 5 is embedded with the hollow elastic tube 201, and the discharge end of the discharge tube 5 is fixedly connected to the hollow elastic tube 201; the lower end of the hollow elastic tube 201 passes through the discharge tube 5, and the lower end of the hollow elastic tube 201 is provided with an extension portion; a rotating pull tab 202 is rotatably connected in the hollow rotating ring 106 through a torsion spring, and the rotating pull tab 202 is located behind the extension portion of the hollow elastic tube 201; a limit strip 203 is fixedly connected in the discharge tube 5, and the limit strip 203 is located in the cavity surrounded by the hollow rotating tab 105 and the hollow rotating ring 106, and the limit strip 203 is located behind the rotating pull tab 202.

[0059] It also includes an air jet tube 2011 , and the hollow elastic tube 201 is connected to a plurality of air jet tubes 2011 .

[0060] The jet pipe 2011 is convexly arranged on the surface of the hollow elastic tube 201, and is obliquely arranged with the left side lower and the right side higher when viewed from the front of the device; the oblique arrangement of the jet pipe 2011 increases the contact surface between the hollow elastic tube 201 and the material, making it easier to pull the clumped material evenly.

[0061] The principle of dense phase conveying device for conveying materials is that when the airflow pressure reaches a certain value, the materials will be pushed out in a mass. As the airflow pressure decreases, the material discharge speed slows down until the next pressure peak arrives and the materials are discharged in a mass again. Therefore, the materials are conveyed in a Fig.11 As shown, the material 11 in the discharge pipe 5 is discharged in a clustered state at intervals, which results in the agglomerated material being more easily stuck in the discharge pipe 5 (especially the bent portion of the discharge pipe 5) during actual operation of the device.

[0062] Therefore, when the external air pump connected to the air valve 107 drives the hollow rotating wheel 101, the hollow rotating wheel 101 rotates counterclockwise from a top-down perspective. When the hollow rotating wheel 101 rotates, it drives the hollow rotating ring 106 to rotate, and the hollow rotating ring 106 drives the rotating pull tab 202 to move. Fig.10 As shown in the figure, the rotating pull tab 202 will hook the extended portion of the hollow elastic tube 201 during the movement, and the rotating pull tab 202 will pull the hollow elastic tube 201 during the movement. After the hollow elastic tube 201 is pulled, it will slide on the discharge tube 5, and the hollow elastic tube 201 is embedded in the discharge tube 5, so it will not lose contact with the discharge tube 5, and at this time, the hollow elastic tube 201 will be pulled in the pulling direction 10, and at this time, the hollow elastic tube 201 is as shown in FIG. Fig.11 As shown, the hollow elastic tube 201 will move along the pulling direction 10. When the hollow elastic tube 201 moves, there is friction between the part in contact with the material. When the hollow elastic tube 201 moves, it will drive the contacted material to move. At this time, the part in contact with the agglomerated material and the hollow elastic tube 201 will flow to the empty area obliquely below, so that the material can be transported more evenly, avoiding the problem of the material being easily stuck when transporting the material in the prior art.

[0063] When the hollow rotating ring 106 drives the rotating pull tab 202 to rotate counterclockwise, the rotating pull tab 202 moves to the preset position and contacts with the limiting strip 203. Since the rotating pull tab 202 is continuously rotating and the rotating pull tab 202 is rotatably connected to the hollow rotating ring 106 through the torsion spring, the rotating pull tab 202 rotates toward the outer ring surface of the hollow rotating ring 106 under the pressure of the limiting strip 203. At this time, the rotating pull tab 202 releases the pulling of the hollow elastic tube 201. Due to the elasticity of the hollow elastic tube 201, the hollow elastic tube 201 will return to its initial state. The rotating pull tab 202 is driven by the hollow rotating ring 106 to separate from the limiting strip 203. At this time, the rotating pull tab 202 will also return to its initial state. In this way, the rotating pull tab 202 completes a working cycle.

[0064] Furthermore, the device is also provided with a connecting pipe 1051. When the external air pump connected to the air valve 107 drives the hollow rotary wheel 101, due to the setting of the connecting pipe 1051, the connecting pipe 1051 connects the cavity of the hollow rotating plate 105 and the cavity of the hollow rotating ring 106. The air in the hollow cleaning strip 104 will pass through the hollow rotating plate 105, the connecting pipe 1051 and the hollow rotating ring 106 in turn, and then enter the hollow elastic tube 201. The air entering the hollow elastic tube 201 will be ejected from the jet pipe 2011. In this way, when the hollow elastic tube 201 drives the agglomerated material to be conveyed more evenly, the air ejected from the jet pipe 2011 further assists in impacting the agglomerated material, making the agglomerated material easier to be in a uniform state, and also reduces the friction between the agglomerated material and the discharge pipe 5, so that the friction loss of the material and the discharge pipe 5 is smaller.
