Description

Technical Field

[0001] The utility model relates to the technical field of fly ash conveying equipment, in particular to a comprehensive experimental device for pneumatic conveying equipment. Background Art

[0002] In existing thermal power plants, slag is typically transported through fly ash conveying systems. Fly ash conveying systems are a common type of conveying system.

When in use, the compressed gas provided by the air source enters the machine body through the air inlet port, and then the compressed gas enters the ash conveying pipeline through the air outlet port. When the compressed gas passes through the material connection port, negative pressure is formed, and the powder in the powder silo enters the machine body and is blown into the ash conveying pipeline by the compressed gas.

[0006] After production, pneumatic conveyors are usually first tested for pressure tightness in air tightness test equipment, and then placed in corrosion performance test equipment for testing.

[0017] When conducting air tightness and corrosion resistance tests on pneumatic conveying equipment, workers first connect the air inlet end of the pneumatic conveyor to the air inlet pipe, then connect the air outlet end of the pneumatic conveyor to the air outlet pipe, and at the same time close the material connection port. Then, the worker clamps the positive electrode clamp on the pneumatic conveyor. After the connection is completed, the worker sinks the pneumatic conveyor into the electrolyte of the test pool. After the connection is completed, the worker turns on the air pump and the battery at the same time.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See Figure 1-2 As shown, a comprehensive experimental device for pneumatic conveying equipment includes a square body 1, in which a square test pool 11 with an open top is provided. The test pool is filled with an electrolyte. The electrolyte can meet the experimental conditions for corrosion resistance test and air tightness test. Electrolysis equipment and air supply equipment are arranged in the test pool 11, so that the test pool 11 can simultaneously perform air tightness test and corrosion resistance test of the pneumatic conveyor 9, thereby achieving the effect of improving the convenience of performing air tightness and corrosion resistance tests of the pneumatic conveyor 9.

[0025] The body 1 is provided with a placement cavity 2 at a position away from the test pool 11, and an air pump 21 is placed in the placement cavity 2. The air pump 21 is connected to an air intake pipe 3 made of rubber material. The air intake pipe 3 passes through the body 1 and is located in the test pool 11. The end of the air intake pipe 3 located in the test pool 11 is connected to an air intake connecting hose 31 made of rubber material. One end of the air intake connecting hose 31 is threadedly connected to the air intake pipe 3, and the other end extends out of the electrolyte. The end of the air intake connecting hose 31 extending out of the electrolyte is provided with an air intake connecting pile 311 made of rubber material.

[0026] An outlet pipe 4 is provided at a position opposite the test cell 11 and the air inlet pipe 3. The outlet pipe 4 passes through the body 1, and the end of the outlet pipe 4 away from the air inlet pipe 3 is located outside the test cell. A rubber outlet connection hose 41 is connected to the end of the outlet pipe 4 located in the test cell 11. One end of the outlet connection hose 41 is threadedly connected to the outlet pipe 4, and the other end extends out of the electrolyte. A rubber outlet connection post 411 is provided at the end of the outlet connection hose 41 extending out of the electrolyte. Rubber material has good corrosion resistance, thereby reducing the loss of the air inlet pipe 3, the air outlet pipe 4, the air inlet connection hose 31, and the air outlet connection hose 41 in the electrolyte, thereby increasing the service life of the air inlet pipe 3, the air outlet pipe 4, the air inlet connection hose 31, and the air outlet connection hose 41.

[0027] A square battery 5 is connected to the top of the test pool 11 through a fixing assembly 6. The fixing assembly 6 is used to fix the battery 5 on the top of the test pool 11. The fixing assembly 6 includes a long fixed beam 61 made of solid wood. Both ends of the fixed beam 61 are fixedly connected to the top of the test pool 11. The top of the fixed beam 61 is connected to a square fixing seat 62. The battery 5 is fixedly connected to the fixing seat 62. An air intake suspension hook 7 and an air outlet suspension hook 8 are fixedly connected to the side of the fixed beam 61 facing the test pool 11. The air intake suspension hook 7 is located at a position of the fixed beam 61 near the air intake pipe 3, and the air outlet suspension hook 8 is located at a position of the fixed beam 61 near the air outlet pipe 4. The end of the air intake connecting hose 31 extending out of the electrolyte is hung in the air intake suspension hook 7, and the end of the air outlet connecting hose 41 extending out of the electrolyte is hung in the air outlet suspension hook 8.

[0028] The battery 5 is connected to a positive electrode clamp 51 and a negative electrode clamp 52 through wires. The negative electrode clamp 52 holds a lead rod 53. The end of the lead rod 53 away from the negative electrode clamp 52 is inserted into the detection pool, and the end of the lead rod 53 abuts against the bottom wall of the detection pool.

[0029] A specific application of this embodiment is:

[0030] When testing the airtightness and corrosion resistance of the pneumatic conveying equipment, workers first seal the material connection port. They then remove the air inlet connection post 311, which rests on the air inlet hook 7. They then connect the air inlet end of the pneumatic conveyor 9 to the air inlet connection post 311. Finally, they connect the pneumatic conveyor 9 to the air outlet connection post 411, which rests on the air outlet hook 8. Finally, they clamp the positive electrode clamp 51 onto the pneumatic conveyor 9 and lower it into the electrolyte.

[0031] After the pneumatic conveyor 9 is sunk into the electrolyte, the worker starts the air pump 21 and the battery 5 at the same time. The startup time is 1 minute. The airflow generated by the air pump 21 enters the pneumatic conveyor 9 through the air inlet pipe 3, the air inlet connecting hose 31 and the air inlet connecting pile 311. Since the material connection port of the pneumatic conveyor 9 is closed, the airflow entering the pneumatic conveyor 9 passes through the air outlet pipe 4, the air outlet connecting hose 41 and the air outlet connecting pile 411 and is discharged. If the airtightness of the pneumatic conveyor is poor, rapidly rising bubbles will be generated in the electrolyte, and the results of the airtightness test will be obvious. After the battery 5 is started, the battery 5 supplies power to the lead rod 53 through the negative clamp 52, and the battery 5 supplies power to the pneumatic conveyor 9 through the positive clamp 51, and the electrolytic reaction is carried out with the electrolyte as the reaction site. After the battery 5 stops supplying power, the pneumatic conveyor 9 is immersed in the electrolyte for a period of time. The worker then removes the pneumatic conveyor 9 from the electrolyte and tests the corrosion resistance of the pneumatic conveyor 9 by observing the piles on the surface of the pneumatic conveyor 9. In summary, the above steps improve the convenience of testing the airtightness and corrosion resistance of the pneumatic conveyor 9.

[0032] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should fall within the scope of protection of the present invention.
