Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen preparation, in particular to nitrogen making equipment with a rapid cold start function. Background Art

[0002] There are three main types of nitrogen manufacturing processes, namely cryogenic air separation, molecular sieving and membrane air separation. Cryogenic air separation is to liquefy compressed air and then distill it, and separate nitrogen through the principle of different boiling points between gases. In the preparation process of nitrogen, in order to ensure the purity of the air, various equipment is usually used to remove dust, moisture, etc. from the air. Among them, the cold dryer condenses and discharges the moisture in the air through cooling, thereby achieving the effect of drying the air.

[0003] A compressed air dehydration cold dryer with application number 202322609338.4 comprises a cold dryer body, and a baffle is arranged between the inner walls of the cold dryer body; the utility model rotates a rotating head, and the rotation of the rotating head drives the rotating rod to rotate, and the rotation of the rotating rod drives the rotating disk to rotate, and the rotation of the rotating disk drives the transmission rod to move, and the movement of the transmission rod drives the connecting rod to move, and the movement of the connecting rod drives the connecting rod to move, and the movement of the connecting rod causes the connecting rod to disengage from the inner wall of the cold dryer body, and the baffle is removed for maintenance, which can achieve the purpose of facilitating maintenance, reducing workload and improving maintenance efficiency. The utility model drives the tightening mechanism to rotate by the rotation of the motor, and the rotation of the tightening mechanism drives the rotating block to rotate, and the rotation of the rotating block drives the brush to rotate, and the brush rotates to clean the filter, which can achieve the purpose of filtering and cleaning, reducing the amount of maintenance and ensuring the efficiency of the cold dryer.

[0004] This technical solution uses an electric motor to drive the brush to rotate to clean the dust net, but the friction between the brush and the dust net is relatively large when working. First, it is easy to aggravate the wear of the brush, thereby affecting the service life of the brush. Second, the brush is usually made of plastic bristles, which are relatively fine. The pressure applied by the second spring can easily cause the bristles to pass through the dust net. Once the bristles break, they will enter the inside of the cold dryer. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a nitrogen production equipment with a rapid cold start function to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a nitrogen production equipment with a rapid cold start function, including a cold dryer, a bracket is fixed on the top of one side of the cold dryer, and one side of the inside of the bracket is connected to a striking frame through a buffer sealing pad, a second dustproof net is installed inside the striking frame, an electromagnet is installed on the other side of the bracket, a striking rod is connected to the inside of the bracket, and a spring is sleeved on the outside of the striking rod.

[0007] By adopting the above technical solution, when the dust-proof net is blocked, the electromagnet opens and closes several times. After the electromagnet is started, it attracts the striking rod, causing the striking rod to move away from the struck frame and compress the spring. After the electromagnet is closed, the spring drives the striking rod to displace, causing the striking rod to collide with the struck frame. Since one end of the striking rod and the struck frame are both made of high-strength steel, the structural strength is relatively high, effectively avoiding the occurrence of damage. Then, the struck frame and the dust-proof net vibrate under the influence of the impact force. And because the dust-proof net is inclined, the dust on the dust-proof net falls off and separates from the dust-proof net under the dual action of gravity and vibration force. And through the setting of the buffer sealing pad, on the one hand, it avoids the struck frame transmitting force to the bracket, and on the other hand, it avoids dust entering from the gap between the struck frame and the bracket.

[0008] Furthermore, the buffer sealing pad is made of nitrile rubber.

[0009] By adopting the above technical solution, on the one hand, it avoids the struck frame transmitting force to the bracket, and on the other hand, it avoids dust entering from the gap between the struck frame and the bracket.

[0010] Furthermore, one end of the striking rod is spherical, and one end of the striking rod and the struck frame are both made of high-strength steel.

[0011] By adopting the above technical solution, since one end of the striking rod and the struck frame are both made of high-strength steel, the structural strength is relatively high, effectively avoiding the occurrence of damage.

[0012] Furthermore, the other end of the striking rod is in a "T" shape, and the other end of the striking rod is made of iron material.

[0013] By adopting the above technical solution, after the electromagnet is started, it attracts the striking rod, causing the striking rod to move away from the struck frame and compress the spring.

[0014] Furthermore, the striking rod is slidably connected to the bracket and abuts against the struck frame.

[0015] By adopting the above technical solution, after the electromagnet is closed, the spring drives the striking rod to displace, causing the striking rod to collide with the struck frame.

[0016] Furthermore, the second dust-proof net is inclined.

[0017] By adopting the above technical solution, due to the inclination of the second dust-proof net, the dust on the second dust-proof net falls off and separates from the second dust-proof net under the dual action of gravity and vibration force.

[0018] Furthermore, a control panel is installed above the outer surface of the cold dryer, a maintenance door is connected below the outer surface of the cold dryer, an air inlet and an air outlet are respectively connected to both sides of the top of the cold dryer, a liquid discharge port is connected below one side of the cold dryer, and a first dust-proof net is installed above the other side of the cold dryer.

[0019] By adopting the above technical solution, the staff can turn on the cold dryer through the control panel. Compressed air enters the interior of the cold dryer through the air inlet. Inside the cold dryer, the compression refrigeration system cooperates with the heat exchange structure to reduce the temperature of the compressed air, so that the moisture in the compressed air condenses and is discharged from the drain port. Then, the dried compressed air rushes out of the air outlet, and the cooling air flow enters the interior of the cold dryer through the second dust-proof net and the bracket, and then is discharged from the first dust-proof net, thus facilitating the heat dissipation of the compression refrigeration system.

[0020] Furthermore, the electromagnet is electrically connected to the control panel.

[0021] By adopting the above technical solution, when the dust-proof net is blocked, the staff can open and close the electromagnet several times through the control panel. After the electromagnet is started, it attracts the striker rod, and after the electromagnet is turned off, the attraction to the striker rod ends.

[0022] Furthermore, a flow meter is installed at the top of the air inlet, and a temperature sensor is installed in the middle of the top of the cold dryer.

[0023] By adopting the above technical solution, when the container for storing nitrogen or liquid nitrogen is full, the entire nitrogen production system stops working, but the temperature of the heat exchange structure in the cold dryer is monitored through the temperature sensor. When the temperature of the heat exchange structure in the cold dryer rises, the cold dryer automatically starts to reduce the temperature of the heat exchange structure in the cold dryer, so that when the nitrogen in the container is consumed and the nitrogen production system restarts to produce nitrogen, there is no need to wait for the cold dryer to cool down again. Compressed air can be directly introduced for cold drying treatment, achieving the effect of cold start, reducing the waste of time, and the flow meter monitors the entry of compressed air to keep the cold dryer running, effectively avoiding the phenomenon that the temperature in the cold dryer rises after a short shutdown and waiting for the cold dryer to be precooled when starting nitrogen production again.

[0024] Furthermore, both the flow meter and the temperature sensor are electrically connected to the control panel.

[0025] By adopting the above technical solution, the temperature of the heat exchange structure in the cold dryer is monitored through the temperature sensor. When the temperature of the heat exchange structure in the cold dryer rises, the cold dryer automatically starts to reduce the temperature of the heat exchange structure in the cold dryer.

[0027] Through the settings of a buffer gasket, a struck frame, a second dust-proof net, a striking rod, a spring, and an electromagnet, when the dust-proof net is blocked, the electromagnet opens and closes several times. After the electromagnet is activated, it attracts the striking rod, causing the striking rod to move away from the struck frame and compress the spring. After the electromagnet is turned off, the spring drives the displacement of the striking rod, causing the striking rod to impact the struck frame. Since one end of the striking rod and the struck frame are both made of high-strength steel, the structural strength is relatively high, effectively avoiding the occurrence of breakage. After that, the struck frame and the dust-proof net vibrate under the influence of the impact force. And because the dust-proof net is inclined, the dust on the dust-proof net falls off and separates from the dust-proof net under the dual action of gravity and vibration force. And through the setting of the buffer gasket, on the one hand, it avoids the struck frame from transmitting force to the bracket, and on the other hand, it avoids dust from entering through the gap between the struck frame and the bracket; it is convenient to clean the dust-proof net, effectively avoiding blockage, and has a long service life.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.

[0034] The following will describe the embodiments of the present utility model according to the overall structure of the present utility model.

[0035] Embodiment 1:

[0036] A nitrogen production device with a fast cold start function, such as Figures 2 - 4As shown in the figure, it includes a refrigerated dryer 1. Above one side of the refrigerated dryer 1, a bracket 10 is fixed. Inside one side of the bracket 10, a struck frame 12 is connected through a buffer seal 11. The buffer seal 11 is made of nitrile rubber. One is to prevent the struck frame 12 from transmitting force to the bracket 10, and the other is to prevent dust from entering through the gap between the struck frame 12 and the bracket 10. Inside the struck frame 12, a second dust-proof net 13 is installed. The second dust-proof net 13 is inclined. The struck frame 12 and the dust-proof net vibrate under the influence of the impact force. And because the second dust-proof net 13 is inclined, the dust on the second dust-proof net 13 falls off and separates from the second dust-proof net 13 under the dual action of gravity and vibration force. On the other side inside the bracket 10, an electromagnet 16 is installed. The electromagnet 16 is electrically connected to the control panel 2. The other end of the striking rod 14 is in a "T" shape. The other end of the striking rod 14 is made of iron material. After the electromagnet 16 is started, it attracts the striking rod 14, making the striking rod 14 move away from the struck frame 12 and compress the spring 15. Inside the bracket 10, a striking rod 14 is connected. One end of the striking rod 14 is spherical. One end of the striking rod 14 and the struck frame 12 are both made of high-strength steel. The striking rod 14 is slidably connected to the bracket 10. The striking rod 14 abuts against the struck frame 12. A spring 15 is sleeved outside the striking rod 14. After the electromagnet 16 is turned off, the spring 15 drives the displacement of the striking rod 14, making the striking rod 14 impact the struck frame 12. Since one end of the striking rod 14 and the struck frame 12 are both made of high-strength steel, the structural strength is relatively high, effectively avoiding the occurrence of damage phenomena.

[0037] Refer to Figure 1 and Figure 2 In the above embodiment, a control panel 2 is installed above the outer surface of the refrigerated dryer 1 for convenient control of the opening and closing of the refrigerated dryer 1; a maintenance door 3 is connected below the outer surface of the refrigerated dryer 1 for convenient maintenance; on both sides of the top of the refrigerated dryer 1, an air inlet 6 and an air outlet 5 are respectively connected. Below one side of the refrigerated dryer 1, a drain port 4 is connected. Compressed air enters the inside of the refrigerated dryer 1 through the air inlet 6. Inside the refrigerated dryer 1, the compressed air temperature is reduced through the cooperation of the compressor refrigeration system and the heat exchange structure, so that the moisture in the compressed air condenses and is discharged from the drain port 4. Then the dried compressed air rushes out of the air outlet 5. Above the other side of the refrigerated dryer 1, a first dust-proof net 7 is installed. The heat dissipation air flow enters the inside of the refrigerated dryer 1 through the second dust-proof net 13 and the bracket 10, and then is discharged from the first dust-proof net 7, so as to facilitate the heat dissipation of the compressor refrigeration system.

[0038] Embodiment 2:

[0039] When the container storing nitrogen or liquid nitrogen is full, the entire nitrogen generation system including the cold dryer 1 stops working. At this time, affected by the external temperature, the temperature of the cold dryer 1 rises. When the nitrogen generation system starts working again, compressed air is input into the cold dryer 1. Since the temperature inside the cold dryer 1 has risen, the drying effect is reduced. Therefore, it is necessary to wait for a period of time for the cold dryer 1 to be precooled, resulting in a waste of time. To avoid the above phenomenon, based on the above-mentioned Embodiment 1, the following settings are now made.

[0040] Refer to Figure 1 and Figure 2 , in the above embodiment, a flow meter 8 is installed at the top of the air inlet 6. When the flow meter 8 monitors the entry of compressed air, the cold dryer 1 is started to keep running; a temperature sensor 9 is installed in the middle of the top of the cold dryer 1. Both the flow meter 8 and the temperature sensor 9 are electrically connected to the control panel 2. The temperature of the heat exchange structure inside the cold dryer 1 is monitored through the temperature sensor 9. When the temperature of the heat exchange structure inside the cold dryer 1 rises, the cold dryer 1 is automatically started to lower the temperature of the heat exchange structure inside the cold dryer 1.

[0041] The implementation principle of the present utility model is as follows: First, the staff turns on the cold dryer 1 through the control panel 2. Compressed air enters the inside of the cold dryer 1 through the air inlet 6. Inside the cold dryer 1, the compressed air temperature is lowered through the cooperation of the compression refrigeration system and the heat exchange structure, so that the moisture in the compressed air condenses and is discharged from the liquid discharge port 4. Then, the dried compressed air rushes out of the air outlet 5, and the heat dissipation air flow enters the inside of the cold dryer 1 through the second dust-proof net 13 and the bracket 10, and then is discharged from the first dust-proof net 7, thus facilitating the heat dissipation of the compression refrigeration system;

[0042] When the container storing nitrogen or liquid nitrogen is full, the entire nitrogen generation system stops working, but the temperature of the heat exchange structure inside the cold dryer 1 is monitored through the temperature sensor 9. When the temperature of the heat exchange structure inside the cold dryer 1 rises, the cold dryer 1 is automatically started to lower the temperature of the heat exchange structure inside the cold dryer 1. Thus, when the nitrogen in the container is consumed and the nitrogen generation system is restarted to start nitrogen generation, there is no need to wait for the cold dryer 1 to cool down again, and compressed air can be directly introduced for cold drying treatment, achieving the effect of cold start, reducing the waste of time, and the flow meter 8 monitors the entry of compressed air to start the cold dryer 1 to keep running, effectively avoiding the phenomenon that the temperature inside the cold dryer 1 rises after a short shutdown and waiting for the cold dryer 1 to be precooled when nitrogen generation starts again;

[0043] When the dust-proof net is blocked, the staff opens and closes the electromagnet 16 several times through the control panel 2. After the electromagnet 16 is activated, it attracts the striking rod 14, causing the striking rod 14 to move away from the struck frame 12 and compress the spring 15. After the electromagnet 16 is turned off, the spring 15 drives the striking rod 14 to displace, causing the striking rod 14 to collide with the struck frame 12. Since one end of the striking rod 14 and the struck frame 12 are both made of high-strength steel, the structural strength is relatively high, effectively avoiding the occurrence of damage. After that, the struck frame 12 and the dust-proof net vibrate under the influence of the impact force. And because the second dust-proof net 13 is inclined, the dust on the second dust-proof net 13 falls off and separates from the second dust-proof net 13 under the dual action of gravity and vibration force. And through the setting of the buffer sealing pad 11, first, it avoids the struck frame 12 from transmitting force to the bracket 10, and second, it avoids dust from entering through the gap between the struck frame 12 and the bracket 10.

[0044] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and are not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not make creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
