The discharge pipeline 9 is also connected with a charging hose 19, and the storage tank 4 is provided with a feed pipeline 8 (hose). the

Described frame body 1 is provided with program control box 10, and the bottom of frame body 1 is provided with castor, and storage tank 4 is provided with observation window 100, electric contact vacuum meter 11,12. the

The feed pipeline 8 is provided with a negative pressure guarantee valve 81, feed valves A2, B2, and the feed valves A2, B2 are electric butterfly valves. the

Signal devices 200 and 201 are provided on the bearing spring 13 . the

The discharge pipeline 9 is provided with discharge valves A3, B3, the discharge valves A3, B3 are electric butterfly valves, and the lower end of the discharge valves A3, B3 is provided with a guide bin 14. the

The front end of the dust collection bag 18 is provided with an airflow regulating valve 17, and the front end of the airflow regulating valve 17 is provided with a filter bin 15, the filter bin 15 is provided with a filter screen 16, and the upper end is connected with a filling hose 19. The program control box 10 controls the work of negative pressure cut-off valves A1, B1, feed valves A2, B2, discharge valves A3, B3, nozzle valve C1, positive pressure intake valves C2, C3. the

This program is implemented through the following steps:

Press the SB1 start switch on the program control box 10, the air compressor 3 starts to work, until the pressure of the air storage tank is 1.0Mpa; at the same time, the negative pressure vacuum pump 2 operates (when filling, there is no no-load), and the A and B storage tanks 4 Carry out evacuation to negative pressure, at this time, the working status of each valve is as follows:

Table I

Because the vacuum degree lower limit of the A tank vacuum gauge of the storage tank 4 is set to: -0.0055Mpa, the vacuum degree of the B tank (11B) is set to: 0.0065Mpa. When the vacuum degree of the A tank of the storage tank 4 drops to When -0.0055Mpa, the working status of each valve is as follows:

Table II

That is: the negative pressure guarantee valve 81 is opened, and the feed valve A2 is opened. At this time, the feed pipe 8 is inserted into the raw material barrel 400. Under the action of negative pressure, the raw materials (molecular sieve, alumina, etc.) are sucked into the storage tank 4 At this time, the vacuum degree of the B tank of the storage tank 4 is more difficult to reach 0.0065Mpa; when the feed of the A tank of the storage tank 4 makes the pressure spring 13 compressed to ① and ③ of the signal device 200 are connected At this time, basically the feed of tank A of storage tank 4 is full (the pressure switch is adjustable), and the switching status of each valve is as follows:

Table 3

Because the negative pressure cut-off valve A1 is closed, the feed valve A2 is closed, and the intake valve C2 is opened, the air storage tank quickly inflates the A tank of the storage tank 4 to about 0.8Mpa, and the discharge valve A3 is also opened at the same time, and the storage tank The molecular sieve in tank A of feed tank 4 flows out to the guide bin 14 through the discharge pipeline 9 under the thrust of its own gravity and 0.8Mpa air pressure. A slide plate like a pattern is designed in the guide chamber. At this time, the 0.65Mpa air pressure from the pressure reducing valve 300, with the help of the nozzle solenoid valve C1, pushes the molecular sieve to the filter chamber 15 with a large air flow (because the pressure on the filter chamber is the lowest) After the dust is filtered out through the filter chamber 15, it is filled into the adsorption device 500 by the filling hose 19 under the action of air pressure. the

During this period, the feeding of the B tank of the storage tank 4 makes the pressure spring 13 compressed until the ① and ③ of the signal device 201 have been connected, but since the ① and ② of the signal device 200 have not been reset, the A of the storage tank 4 will After the raw materials in the tank are discharged, the pressure spring 13 under the A tank of the storage tank 4 is gradually restored, so that the ① and ② of the signal device 200 are connected, and after a delay of 2 seconds, the valves are switched as follows:

Table 4

Now, the vacuum degree of the A tank of the storage tank 4 has not yet dropped to the lower limit value, and the negative pressure guarantee valve 81 is closed. When the vacuum degree of the A tank of the storage tank 4 drops to -0.0055Mpa, the negative pressure Guaranteed valve 81 is opened, and tank A begins to suck raw material again. the

At the same time, because the negative pressure cut-off valve B1 is closed, the feed valve B2 is closed, the intake valve C3 is opened, the air storage tank quickly inflates the B tank to about 0.8Mpa, the discharge valve B3 is also opened, and the storage tank Molecular sieve in tank B of 4 is driven by its own gravity and 0.8Mpa air pressure, and flows out to the guide warehouse 14 through the discharge pipeline 9. As mentioned above, a slide plate such as a pattern is designed in the guide warehouse 14. The 0.65Mpa air pressure of the valve 300, with the help of the nozzle solenoid valve C1, pushes the molecular sieve to the filter chamber 15 (because the pressure of the filter chamber is the lowest) with the help of the nozzle solenoid valve C1. The tube 19 is filled to the adsorption device 500 under the action of air pressure. the

During this period, the feeding of the A tank of the storage tank 4 makes the pressure-bearing spring 13 compressed until ① and ③ of the signal device 200 have been connected, but because ① and ② of the signal device 201 have not been reset, waiting for the ① and ② of the signal device 201 to be turned on The raw material of tank B goes out, and the bearing spring 13 under the tank B of material storage tank 4 recovers gradually, makes 1. and 2. connect of signal device 201, and after delaying 2 seconds equally, the state of each valve returns again as: ( Table three), the A tank discharge of the storage tank 4, the B tank feed of the storage tank 4, start the next round of circulation. the

Upturned filter screen 16 is designed in the filter chamber 15, and the smooth surface is conducive to upward flow, and the filter screen is used for filtering dust. The regulating valve 17 is used to control the micro air volume to drive the dust into the dust bag 18 . the

The electric contact vacuum gauges 11 and 12 control the negative pressure guarantee valve 81. When the pressure in tank A of the storage tank 4 and tank B of the storage tank 4 is lower than the set lower limit negative pressure, the negative pressure guarantee valve 81 is closed . Reduce the load of negative pressure vacuum pump 2, and save energy. the

SB3 on the program control box 10 is an emergency switch, and after being pressed at any time, the discharge valves A3 and B3 are closed, and the filling stops. Press it again, and the filling resumes. the

The filling speed of the machine depends on the size of the negative pressure vacuum pump 2 and the related supporting valves, pipelines, and the displacement of the air compressor 3. For example: a vacuum pump with a suction pressure of 0.008Mpa and a pumping rate of 70L/S, equipped with a 50mm feed valve and suction pipe; equipped with a 40mm discharge valve and pipe, equipped with an exhaust volume of 1.0m3/ min air compressor, it can fill about 80 kg of molecular sieve in 10 minutes. Especially for some large-scale adsorption equipment, several tons of molecular sieves are needed for one machine, and the filling port of the equipment is as high as 3-4 meters, so it needs lifting equipment and multiple people to work. The utility model saves labor and time, is several times faster than manual filling at present, and is simple and safe to operate. the

Similarly, it is also suitable for the replacement of old equipment raw materials. Promptly use feed pipeline 8 to suck out the raw material of old equipment. For most of the factories where the equipment is installed on the top floor of the 5th and 6th floors, the old raw materials after replacement can be directly discharged to the downstairs by lengthening the filling hose 19 for processing, and the effect of saving time and effort is more obvious. the

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope . the
