Description

Technical Field

[0001] The invention relates to the technical field of molecular sieve pressing devices for pressure swing adsorption nitrogen making equipment, in particular to a solid material cylinder pressing method and device. Background Art

[0002] In the field of nitrogen production by pressure swing adsorption, most of the nitrogen production carbon molecular sieves are currently used for filling on the market. During the transportation or operation of the filled filling tank, the molecular sieves collide with each other due to the impact of the airflow, resulting in breakage or even gradual pulverization. The volume of the molecular sieves gradually decreases and the service life is shortened. At the same time, the gaps between the molecular sieves gradually increase, resulting in intensified collisions of the molecular sieves, which causes serious pulverization of the molecular sieves, and finally causes the molecular sieves to sink, and the overall stack volume is reduced, resulting in a decrease in gas production and a decrease in gas purity. When the molecular sieve sinks beyond the cylinder stroke, the cylinder cannot play a compacting role, resulting in pulverization of the molecular sieve. In severe cases, the molecular sieve even fails, causing the equipment to fail to operate normally.

[0003] The cylinder pressing methods and devices currently on the market have the following shortcomings: the degree of pressing cannot be accurately judged during cylinder pressing, and excessive pressing can easily lead to material breakage and reduced material performance; the pressing speed of the cylinder pressing process cannot be effectively controlled, which affects the pressing effect and the service life of the device; the cylinder rod cannot be automatically lifted when the molecular sieve sinks beyond the cylinder stroke, making material addition difficult and the degree of automation low; the excess gas in the stuffing tank cannot be discharged to balance the device pressure, and the safety is low.

[0004] A new type of cylinder clamping device (CN 214437732 U) is only provided with an alarm system when the molecular sieve sinks beyond the cylinder stroke, but no automatic control of the cylinder clamping device by the air path system is provided, resulting in that the clamping speed of the cylinder clamping process cannot be effectively controlled, thereby affecting the clamping effect and the service life of the device; when the molecular sieve sinks beyond the cylinder stroke, the cylinder rod cannot be automatically lifted, making it difficult to add materials and the degree of automation is low.

[0005] A molecular sieve cylinder compression device for large-scale nitrogen production equipment (CN 212142038 U) is only provided with a balance detection device when the cylinder is compressed, but no compression degree judgment device and exhaust pipe are provided, resulting in the inability to accurately judge the compression degree when the cylinder is compressed, and it is easy to over-compress and cause the material to break, resulting in reduced material performance, and the excess gas balance device pressure in the filling tank cannot be discharged, which will cause safety hazards during the operation of the equipment.

Furthermore, the air circuit system controls the pushing speed of the cylinder pressing device to ensure that the solid material is tightly pressed to form a stable structure and extend the service life of the device. When the material sinks beyond the cylinder stroke, the alarm system and the air circuit system are jointly controlled to reduce the difficulty of material adding, improve the degree of automation of the device, and effectively solve the technical problems of material collision and crushing caused by material sinking during transportation and operation, as well as excessive material gaps and reduced structural stability.

[0049] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features; in addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0050] The following is combined with Figure 1-6 The present invention is described in further detail.

[0051] like Figures 1 to 6 As shown, a solid material cylinder compacting method and device, comprising:

[0052] The cylinder 1 has a solid material feeding bin 20 disposed on the top of the cylinder 1; the solid material is transported to the feeding bin 20 through a filling pipe 19;

[0053] An exhaust pipe 4, wherein the exhaust pipe 4 is arranged outside the filling pipe 19;

[0054] The gas circuit system is arranged outside the cylinder 5; the gas circuit system controls the start and stop and the lifting speed of the cylinder lifting system;

[0055] A cylinder lifting system, which is arranged at the top of the filling pipe 19;

[0056] A compacting system, which is arranged at the inlet end of the stuffing pipe 19; the compacting system compacts the solid material through the cylinder lifting system;

[0057] A visual positioning system, which is arranged on the top of the cylinder lifting system, and determines the compaction of the solid material by positioning the screw, so as to accurately determine whether the solid material is compacted tightly;

[0058] The alarm and gas direction control system is arranged on the outside of the cylinder 5; the alarm and gas direction control system operates after being connected to the magnetic piston 6 through the magnetic switch 14 on the outside of the cylinder 5.

[0059] Specifically, in this embodiment, the exhaust pipe is arranged on the outside of the stuffing tube 19; the exhaust pipe is arranged on the outside of the stuffing tube; the exhaust pipe 4 is connected to the outer ring pipe 3 of the stuffing tube; the lower end of the outer ring pipe 3 of the stuffing tube is provided with a sieve plate 2. It should be noted that when the solid material sinks, the gas source switch 12 is started to output gas to the cylinder 5 to push the cylinder clamping device 18 downward, which causes the closed volume at the upper end of the cylinder 1 to decrease, and the corresponding gas pressure to increase, that is, the excess gas inside the device enters the outer ring pipe 3 of the stuffing tube through the sieve plate 2, and then is discharged through the exhaust pipe 4 to balance the device pressure and ensure the safe operation of the equipment. It should be noted that the aperture of the sieve plate 2 is smaller than the solid material, so as to avoid carrying the solid material when the excess gas is discharged, and to ensure the quantity of the solid material.

[0060] Specifically, in this embodiment, the gas circuit system includes an air source switch 12, a reversing valve 13, and a flow regulating valve 11; the gas circuit system controls the cylinder lifting system; the gas source switch 12 is connected to the cylinder 5 through the gas circuit; the flow regulating valve 11 is arranged beside the air inlet at the upper and lower ends of the cylinder 5. It should be noted that the flow regulating valve 11 is used to adjust the lifting speed of the lifting cylinder, and is adjusted and set according to the sinking degree of the solid material and the movement amplitude of the positioning screw 7, that is, when the cylinder rod 17 pushes the pressing device 18 to press the solid material, when the pressing device 18 contacts the surface of the solid material, the flow regulating valve 11 at the upper air inlet of the cylinder 5 is adjusted to reduce the speed of the gas entering the cylinder 5, and gradually and slowly press the solid material to avoid the cylinder rod 7 pushing too fast and causing the solid material to be crushed. When the cylinder rod is lifted, a fixed opening of the flow regulating valve 11 is set to prevent the cylinder rod 17 from being damaged due to excessive speed during the ascent. It should be noted that the working principle of the flow control valve 11 is to change the position of the valve core through the signal of the electric actuator. When the electric actuator receives an opening signal, the valve core opens more and the flow rate increases; when it receives a closing signal, the valve core opens less and the flow rate decreases.

[0061] Specifically, in this embodiment, the cylinder lifting system includes a cylinder 5, a cylinder rod 17, and a magnetic piston 6; the cylinder is arranged at the outer top end of the stuffing tube 19; the cylinder rod 17 and the magnetic piston 6 are arranged inside the cylinder 5; the top end of the cylinder rod 17 is connected to the magnetic piston 6, and the bottom end is connected to the cylinder plate 18-1 of the clamping system; the magnetic piston 6 is connected to the visual positioning system; the magnetic piston 6 is connected to the alarm and gas direction control system through the magnetic switch 14. It should be noted that the reversing valve 13 and the alarm 15 can only be started when the magnetic piston 6 is connected to the magnetic switch 14.

[0062] Specifically, in this embodiment, the clamping device 18 includes a cylinder plate 18-1, a clamping plate 18-2, a wire mesh 18-3, and a fiber mat 18-4; the upper surface of the cylinder plate 18-1 is connected to the cylinder lifting system, and the lower surface is connected to the clamping plate 18-2; the lower surface of the clamping plate 18-2 is provided with the wire mesh 18-3; the lower surface of the wire mesh 18-3 is connected to the fiber mat 18-4; the bottom of the fiber mat 18-4 is connected to the wire mesh 18-3; the clamping plate 18-2, the wire mesh 18-3, and the fiber mat 18-4 are assembled according to the above positions to form a clamping device. It should be noted that the wire mesh 18-3 is used to fix the fiber mat 18-4 to form a stable structure to prevent the cylinder 5 from deforming when pushing the material to be compressed and reducing the compression effect, and the aperture of the wire mesh 18-3 is smaller than the solid material to prevent the solid material from being embedded in the fiber mat 18-4 during the compression process to prevent the structure of the clamping device 18 from being damaged.

[0063] Specifically, in this embodiment, the clamping device 18 is connected to the cylinder rod 17. It should be noted that the clamping device 18 compresses the solid material at any time through the push of the cylinder rod 17, so that the solid material is kept in a close contact state in the cylinder body 1, and the solid material is prevented from being crushed due to excessive friction caused by excessive gaps during transportation and production, thereby ensuring the performance of the solid material and the operation efficiency of the device.

[0064] Specifically, in this embodiment, the visual positioning system includes a positioning screw 7, a visual measuring tool 8, a length detector 9, and a controller 10; the visual measuring tool 8 is arranged at the top of the cylinder 5; the positioning screw 7 is arranged inside the visual measuring tool 8; the length detector 9 is located outside the visual measuring tool 8; the length detector 9 is connected to the positioning screw 9 detector; the controller 10 is located outside the visual measuring tool 8. It should be noted that the inner surface of the visual measuring tool 8 is provided with scale lines and scale line control points for observing the movement of the positioning screw 7, and at the same time, for observing the stable position and stable time of the positioning screw 7, so as to realize the accurate determination of the tight compression of the solid material.

[0065] Specifically, in this embodiment, the controller is connected to the length detector 9, the highest scale line control point of the visual measuring tool 8, and the air source switch 12. It should be noted that when the positioning screw 7 moves a certain length in the visual measuring tool 8, the detector on the top of the positioning screw 7 contacts the scale line control point in the visual measuring tool 8, thereby generating an electrical signal, which is fed back to the length detector 9, and then the controller 10 can transmit a signal to the air source switch 12, start the air circuit to supply air to the cylinder to push the cylinder rod 17 so that the clamping device 18 clamps the material, thereby reducing the gap between the solid materials. When the positioning screw 7 no longer moves and stabilizes at a certain value for 3 minutes, the solid material is compressed to a tight and structurally stable state.

[0066] Specifically, in this embodiment, the alarm and gas control system includes an automatic controller 16, an alarm 15, a reversing valve 13, and a magnetic switch 14; the alarm 15 is connected to the automatic controller 16 through a line; the automatic controller 16 is connected to the magnetic switch 14 and the reversing valve 13 through a line; it should be noted that the alarm 15 is used to remind the staff to prepare for adding solid materials when the solid materials sink too much. When the solid materials sink too much and cannot be compacted, the magnetic piston 6 is connected to the magnetic switch 14, and an electrical signal is generated, which is then transmitted to the automatic controller 16, so that the alarm 15 is activated to achieve a warning effect, reminding the staff to add solid materials and preventing the cylinder compacting device from being damaged due to air compression.

[0067] Specifically, in this embodiment, the reversing valve 13 is connected to the alarm 15 and the automatic controller 16 of the gas control system through a line. It should be noted that the reversing valve 13 is used to control the lifting and lowering of the cylinder rod 17, and the reversing valve 13 can be switched at any time according to the sinking degree of the solid material and the contact between the magnetic piston 6 and the magnetic switch 14. When the solid material sinks too much and cannot be pressed, the magnetic piston 6 is connected to the magnetic switch 14, and an electrical signal is generated, and then the electrical signal is transmitted to the automatic controller 16, thereby controlling the reversing valve 13 to adjust the direction of the gas path, so that the gas is transported to the air inlet at the lower end of the cylinder through the gas path, and then enters the closed area at the lower end of the magnetic piston 6 in the cylinder, so that the gas pressure in this area is greater than the pressure in the closed area at the upper end of the magnetic piston 6, and the cylinder rod 17 moves upward. When the positioning screw in the visual measuring tool 8 reaches the highest scale line, the positioning screw detector is fixed to the scale line control point in the visual measuring tool 8, and then the signal is transmitted to the gas source switch through the controller to close the gas source switch, so as to facilitate the staff to add solid materials to the filling tube. It should be noted that the working principle of the reversing valve 13 is to use the suction force of the electromagnet to manipulate the valve core to change position. There is an electromagnet and a centering spring at each end of the valve. The valve core is in the middle position under normal conditions. When gas is input into the upper port of the cylinder, the upper electromagnet is energized and attracted, and the armature pushes the valve core to the lower end through the push rod, and the airflow passes through the upper end of the reversing valve 13; conversely, when the lower electromagnet is energized and attracted, the airflow passes through the lower end of the reversing valve 13.

[0068] Specifically, in this embodiment, the selection of the alarm 15, the flow control valve 11, and the reversing valve 13 are selected according to the single granular solid material compression requirements and stability. The solid material cylinder compression device of the present invention can be customized and manufactured according to different sizes, different working conditions, and different requirements.

[0069] Specifically, in this embodiment, a solid material cylinder compaction method is characterized by comprising the following steps:

[0070] Step S1, start the gas source switch 12 to energize, adjust the reversing valve 13 to connect the connecting gas path of the air inlet at the upper end of the cylinder, set the flow regulating valve 11, input gas into the cylinder 5, push the cylinder rod 17 to move downward, prompt the clamping device 18 to push the solid material to reduce the gap between the solid materials, and at the same time, the excess gas enters the exhaust pipe through the sieve plate 2 and is discharged to balance the pressure of the device.

[0071] Step S2, observe the movement of the positioning screw 7. When the movement amplitude decreases, adjust the flow control valve 11 to reduce the air supply, and slowly push the clamping device 18 to prevent excessive airflow from pushing the clamping device 18 to over-squeeze the solid material and cause the solid material to be crushed, until the positioning screw 7 stabilizes on the same scale line for a certain period of time, so as to achieve close contact between the solid material and increase the material density to form a stable structure.

[0072] Step S3, when the solid material moves down a long distance, causing the clamping system to be unable to further clamp, and the magnetic piston 6 is connected to the magnetic switch 14, the automatic controller 16 is turned on, adjusting the reversing valve 13, connecting the air path of the air inlet 9 at the lower end of the cylinder 5, and pushing the cylinder rod 17 to move upward. When the positioning screw 7 moves up to the highest scale line, the controller transmits a signal to the air source switch to close the air source switch 12. At the same time, the automatic control switch activates the alarm 15 through the line to remind the staff to add solid materials to the feed pipe, thereby ensuring the safe operation of the device.

[0076] The cylinder pressing method of the present invention is implemented using the above-mentioned material pressing device, and specifically comprises the following steps:

[0077] Step S1, start the gas source switch 12 to energize, adjust the reversing valve 13 to connect the connecting gas path of the air inlet 10 at the upper end of the cylinder, set the flow regulating valve 11, input gas into the cylinder 5, push the cylinder rod 17 to move downward, prompt the clamping device 18 to push the solid material to reduce the gap between the solid materials, and at the same time, the excess gas enters the exhaust pipe through the sieve plate 2 and is discharged to balance the pressure of the device.

[0078] Step S2, observe the movement of the positioning screw 7.

When the positioning screw 7 moves up to the highest scale line, the controller transmits a signal to the air source switch to close the air source switch 12. At the same time, the automatic control switch activates the alarm 15 through the line to remind the staff to add solid materials to the feed pipe, thereby ensuring the safe operation of the device.

[0081] Second embodiment

[0082] The solid material cylinder clamping method and device proposed in the present invention includes five systems, including: an air circuit system, a cylinder lifting system, a clamping system, a visual positioning system, an alarm and air direction control system. The air circuit system includes an air source switch 12, a reversing valve 13, and a flow regulating valve 11; the cylinder lifting system includes a cylinder 5, a cylinder rod 17, and a magnetic piston 6; the clamping system includes a cylinder plate 18-1, a clamping plate 18-2, a screen 18-3, and a fiber mat 18-4; the visual positioning system includes a positioning screw 7, a visual measuring tool 8, a length detector 9, and a controller 10; the alarm and air direction control system includes an automatic controller 16, an alarm 15, a reversing valve 13, and a magnetic switch 14.

[0083] In particular, the solid material crushing situation in the cylinder 1 after using the compaction system and the air path system is compared with the device without using the above-mentioned subsystem. Under normal transportation and production conditions, the solid material crushing rate in the cylinder 1 reaches 26%, and the overall device performance efficiency is 87%. In this patent, the crushing rate of the solid material inside the cylinder is reduced to 14%, and the overall device performance efficiency is increased to 95%.

[0084] Analysis shows that the solid material crushing rate of the solid material compacting device using the compacting system, air path system and cylinder lifting system is reduced, and the overall performance efficiency of the device is improved. At the same time, the solid material compacting device using the alarm and air direction control system and the visual positioning system has a high degree of automation, and can achieve compaction at any time when the solid material gap fluctuates, and ensure the safe operation of the device. This shows that the above five subsystems play a key role and the overall performance of the device is improved.

[0085] Third embodiment

[0086] The solid material cylinder clamping method and device proposed in the present invention includes five systems, including: an air circuit system, a cylinder lifting system, a clamping system, a visual positioning system, an alarm and air direction control system. The air circuit system includes an air source switch 12, a reversing valve 13, and a flow regulating valve 11; the cylinder lifting system includes a cylinder 5, a cylinder rod 17, and a magnetic piston 6; the clamping system includes a cylinder plate 18-1, a clamping plate 18-2, a screen 18-3, and a fiber mat 18-4; the visual positioning system includes a positioning screw 7, a visual measuring tool 8, a length detector 9, and a controller 10; the alarm and air direction control system includes an automatic controller 16, an alarm 15, a reversing valve 13, and a magnetic switch 14.

[0087] In particular, the compaction of the solid material after using the length detector 9 is precisely controlled. When the solid material sinks due to the increase in the gap, the positioning screw 7 moves accordingly in the visual measuring tool. When the moving length of the positioning screw 7 reaches 0.5 meters, the detector at the top of the positioning screw 7 contacts the scale control point in the visual measuring tool, thereby generating an electrical signal. The signal is fed back to the length detector 9, and then the controller can transmit a signal to the air source switch 12, starting the air circuit to supply air to the cylinder 5 to push the cylinder rod 17 so that the clamping device 18 presses the material, thereby reducing the gap between the solid materials. When the positioning screw 7 no longer moves and stabilizes at a certain value for 3 minutes, the solid material is compacted to a tight and structurally stable state, thereby completing the precise control of the compaction of the solid material.

[0088] The granular solid material filling device and sample filling method provided by the present invention have the following beneficial effects:

[0089] The present invention sets a visual measuring tool at the top of the outer side of the cylinder to observe the movement of the positioning screw and tighten the cylinder in time. When the solid material sinks and causes the positioning screw to move, the air path system controls the cylinder lifting system to push the clamping device to reduce the gap between the solid materials and determine the degree of material compression to avoid excessive extrusion and crushing of the material, maintain the material performance and reduce the cost of use.

[0090] The present invention arranges an alarm and gas direction control system outside the cylinder, controls the gas path reversing valve and the alarm according to the contact between the magnetic piston and the magnetic switch inside the cylinder, achieves the effect of joint control, has a high degree of automation, and reduces manpower consumption.

[0091] The present invention arranges an air path system outside the cylinder, and the air supply flow rate can be set according to the compaction condition of the solid material, thereby ensuring that the solid material is compacted tightly, forming a stable structure, and extending the service life of the device.

[0092] The present invention arranges an exhaust pipe outside the filling pipe, so that excess gas can be discharged when the cylinder pressing device presses the solid material, thereby balancing the pressure of the device and ensuring the safe operation of the equipment.

[0093] The devices used in the present invention are all basic facilities produced on the market, which are cheap, simple to produce and process, and convenient to maintain and replace.

[0094] The material compacting device and method of the present invention can be applied to compacting solid materials such as various grains, beans, etc. in addition to being applied to solid materials for nitrogen production equipment, and has wide popularity and market applicability.
