Description

Technical Field

[0001] The utility model relates to the technical field of negative pressure sieving instruments, in particular to a negative pressure sieving instrument for autoclaved aerated concrete blocks. Background Art

[0002] Autoclaved aerated concrete blocks are a kind of porous concrete products made of fly ash, lime, cement, gypsum, slag and other raw materials, with appropriate amount of gas generating agent, regulator, bubble stabilizer, and through the process of batching, mixing, pouring, static stopping, cutting and high-pressure steaming.

[0003] The negative pressure sieving analyzer is a special instrument for sieving and testing. When the negative pressure sieving analyzer uses airflow as the motive medium for sieving, the whole system maintains a negative pressure state. The fine powder material to be tested in the sieve is in a fluid state under the action of the airflow ejected from the rotating air nozzle and moves with the airflow. The fine particles with a particle size smaller than the sieve mesh aperture are driven by the airflow to pass through the sieve and are sucked away, while the coarse particles with a particle size larger than the sieve mesh aperture remain in the sieve, thereby achieving the purpose of screening.

[0004] Negative pressure sieve analyzer usually consists of a sieve base, a micromotor, a vacuum cleaner, a cyclone and electrical control.

[0005] The negative pressure sieving instrument in the prior art sieves concrete powder and extracts small powder. During this process, small powder will continuously pass through the air flow pipe, among which some powder will adhere to the bends of the air flow pipe and accumulate to cause waste of raw materials. In addition, the bends of the pipe are difficult to clean, and excessive accumulation of powder will cause blockage of the pipe, affecting the screening effect. Utility Model Content

[0036] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] like Figure 1~Figure 4As shown, this embodiment proposes an autoclaved aerated concrete block negative pressure sieve analyzer, including a negative pressure sieve analyzer body 1, an airflow pipeline 2, a pipeline cleaning mechanism, a water pump 3, a pipeline drying mechanism and a ventilation sleeve 4, wherein the airflow pipeline 2 is connected to the negative pressure sieve analyzer body 1, the pipeline cleaning mechanism is installed in the negative pressure sieve analyzer body 1, the water pump 3 is fixedly connected to the negative pressure sieve analyzer body 1, the output end of the water pump 3 is connected to the airflow pipeline 2, the pipeline drying mechanism is installed in the negative pressure sieve analyzer body 1, and the ventilation sleeve 4 is provided. There are two air sleeves 4, which are rotatably connected to the two ends of the airflow pipe 2 respectively. When a large amount of small powders are accumulated in the pipe during the operation of the negative pressure sieving instrument, the water pump 3 is first turned on to suck water into the airflow pipe 2 to clean the airflow pipe 2, and then the waste water after cleaning is discharged. Finally, the water remaining in the pipe due to cleaning is dried by the pipe drying mechanism, and the negative pressure sieving instrument continues to work, which solves the problem that the bends of the airflow pipe are difficult to clean, and excessive accumulation of powder will cause blockage of the airflow pipe 2, affecting the screening effect.

[0038] Among them, the pipeline cleaning mechanism includes a support plate 5, a water tank 6, a water shut-off valve 7 and a water outlet pipe 8. The support plate 5 is fixedly connected to the negative pressure sieve analyzer body 1, and the water tank 6 is fixedly connected to the support plate 5. The water tank 6 is connected to the airflow pipeline 2 through a water supply pipe 13. The water shut-off valve 7 is connected to the water supply pipe 13. The water outlet pipe 8 is connected to the output end of the water pump 3. The output end of the water outlet pipe 8 is connected to the outside world. When working, the water shut-off valve 7 is opened, the water pump 3 is started, and the water in the water tank 6 is pumped into the airflow pipeline 2. The water flows through the airflow pipeline 2 to take away the powder in the airflow pipeline 2 and is discharged through the water outlet pipe 8 to clean the pipeline. At the same time, the cleaning machine is more efficient.

[0039] Secondly, the pipeline drying mechanism includes a heating block 9 and a ventilation assembly. There are multiple heating blocks 9, and each ventilation sleeve 4 is fixedly connected with multiple heating blocks 9. The ventilation assembly is installed on the airflow duct 2. The pipeline drying mechanism dries the inside of the duct by heating the airflow entering the airflow duct 2 through the ventilation mechanism, which has the advantages of low cost and high speed.

[0040] Again, the ventilation component includes ventilation holes 10 and exhaust fans 11. There are multiple ventilation holes 10, and multiple ventilation holes 10 are opened on the ventilation sleeve 4 and the airflow duct 2. The exhaust fan 11 is fixedly connected to the support plate 5. The exhaust fan 11 is communicated with the airflow duct 2. The ventilation holes 10 cooperate with the ventilation sleeve 4 to realize the opening and closing of the ventilation holes at any time. When drying is required, the ventilation sleeve 4 is rotated to open the ventilation holes, and the exhaust fan 11 is started to suck the air into the airflow duct 2 through the ventilation holes 10 for circulation. At the same time, the heating block 9 heats the air sucked in by the ventilation holes 10 to dry the air in the airflow duct 2.

[0041] Among them, each of the ventilation sleeves 4 is fixedly connected to a rotating handle 12, and the two ends of the airflow pipeline 2 are respectively connected to a sealing valve 14. The rotating handle 12 is used to facilitate the rotation of the ventilation sleeve 4, and the sealing valve 14 can ensure that the water flow pumped out by the water pump 3 can flow through the entire airflow pipeline 2.

[0042] Finally, the output end of the water outlet pipe 8 can also be connected to the water tank 6 to collect waste water.

[0043] In this embodiment, when cleaning the airflow duct 2, first close the two sealing valves 14, open the water shut-off valve 7, and then turn on the water pump 3. The water pump 3 is started to pump the water 3 in the water tank 6 into the airflow duct 2, and the water flow cleans the airflow duct 2 to bring out the powder. Then, rotate the handle 12 to overlap the vent holes on the ventilation sleeve 4 with the vent holes on the airflow duct 2 to allow air flow to enter, turn on the heating block 9 and the exhaust fan 11, and the exhaust fan 11 will suck the hot air heated by the heating block 9 into the airflow duct 2 to dry the residual moisture in the airflow duct 2. Finally, open the sealing valve 14, close the water shut-off valve 7, and the negative pressure sieve analyzer can continue to work. The cleaning time is short and the cleaning efficiency is high.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
