AI Technical Summary
During the production of concrete water-reducing agents, the water-reducing agent powder particles tend to accumulate on the filter screen during the spray drying process, which prevents the subsequent atomized water-reducing agent from adhering effectively and affects the production effect.
By periodically opening the solenoid valve, compressed air from the external air compressor is instantly introduced into the housing through the split air blow pipe, blowing off the water-reducing agent powder particles on the filter screen. By adjusting the height of the filter screen, accumulation is avoided, ensuring that the water-reducing agent powder particles adhere evenly.
This effectively prevents the accumulation of water-reducing agent powder on the filter screen, ensuring the effective adhesion of the subsequent atomized water-reducing agent and improving production efficiency.

Description
Technical Field
[0001] This utility model relates to the technical field of concrete water-reducing agent production equipment, and in particular to a spray drying filter screen anti-accumulation device for concrete water-reducing agent production. Background Technology
[0002] In the production process of concrete water-reducing agents, the spray drying process is a key step in converting the water-reducing agent solution into a powder product. The atomized water-reducing agent solution adheres to the filter screen, which is then dried at high temperature, removing the moisture and leaving the water-reducing agent powder particles on the screen. However, with prolonged use, the water-reducing agent powder particles will accumulate on the filter screen, preventing subsequent atomized water-reducing agent from effectively adhering to the screen and hindering the processing of the water-reducing agent powder. Therefore, a spray drying filter screen anti-accumulation device for concrete water-reducing agent production is provided. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

An atomizing component is installed on one side of the box body 1, and a high-temperature pipe component is provided on the other side of the box body 1. A blow-off component is provided below the high-temperature pipe component. A top cover 2 is provided at the top of the box body 1. A lifting mechanism is provided at the upper end of the top cover 2. A bracket is connected to the lifting mechanism. The lower end of the bracket extends into the interior of the box body 1 and is connected to an inclined filter screen plate 15. An exhaust hole 20 is provided at the top of one side of the box body 1.
[0021] The blow-off assembly includes branch air pipes 14 that are equidistantly connected to the housing 1, and one end of each branch air pipe 14 is connected to the main air pipe 10. A solenoid valve 9 is installed on the main air pipe 10, and one end of the solenoid valve 9 is connected to the air compressor.
[0022] The atomizing assembly includes an atomizing nozzle 19 connected to the middle of one side of the housing 1. The spray end of the atomizing nozzle 19 is located inside the housing 1. One end of the atomizing nozzle 19 located outside the housing 1 is connected to a feeding pipe 18. One end of the feeding pipe 18 is connected to the material pump body.
[0023] The bracket includes an L-shaped bracket 5 fixed to the upper end of the top cover 2. An electric push rod 4 is fixed to the lower end of the horizontal section of the L-shaped bracket 5, and a crossbar 3 is connected to the lower end of the electric push rod 4.
[0024] The bracket includes two vertical rods 17 connected to both sides of the lower end face of the horizontal section of the crossbar 3. The two vertical rods 17 are movably inserted into the top cover 2, and the two vertical rods 17 extend into the interior of the box 1 and are connected to a U-shaped connecting plate 16. The filter screen 15 is installed obliquely on the U-shaped connecting plate 16.
[0025] The high-temperature pipeline assembly includes hot air distribution pipes 6 fixed at equal intervals on the housing 1, and one end of each hot air distribution pipe 6 is connected to the main hot air pipe 7. The main hot air pipe 7 is provided with a connector 8, and one end of the connector 8 is connected to the air outlet of the high-temperature fan.
[0026] The bottom of the box 1 is provided with a material collection hopper 12, and the lower end of the material collection hopper 12 is connected to a sealing cover 13.

The external controller coordinates and controls the temperature and wind speed of the high-temperature fan to ensure that the moisture is dried to a greater extent.
[0028] Working principle: An external material pump pumps the water-reducing agent solution, causing the atomizing nozzle 19 to spray the solution in a mist onto the filter screen 15. An external high-temperature fan blows hot air into the housing 1 to dry the moisture on the filter screen 15, leaving the water-reducing agent powder on the screen. Some of the water-reducing agent falls into the collection hopper 12 and accumulates. Simultaneously, the electric push rod 4 can be intermittently raised and lowered to adjust the filter screen 15 to different heights, facilitating the spraying of the atomized water-reducing agent solution onto the screen. The filter screen 15 is designed to collect water-reducing agent powder particles uniformly at different locations. By periodically opening the solenoid valve 9, compressed air from the external air compressor enters the housing 1 instantly through the split air pipe 14, blowing off the water-reducing agent powder particles attached to the filter screen 15. The height of the filter screen 15 is continuously adjusted to prevent the water-reducing agent powder particles from accumulating on the filter screen 15, ensuring that the subsequent atomized water-reducing agent can effectively adhere to the filter screen 15, thereby improving the production effect of the water-reducing agent. The water-reducing agent powder can be discharged by unscrewing the sealing cap 13.
