DETAILED DESCRIPTION

[0021] The invention discloses an intelligent deflocculation device for an air inlet of a ventilation system. The deflocculation device is installed indoors and is close to the position of a louver of the ventilation system.

[0022] The deflocculation device is composed of five parts: a deflocculation device bracket 1, a filter screen 2, a cleaning mechanism 3, a collection mechanism 4, and a control system 5. The deflocculation device bracket 1 is welded or bolted as a whole by steel pipes, supporting the cleaning system, effectively improving stability, and reducing the space occupied by the device. The filter screen 2 is fixed to the deflocculation device bracket 1 through a filter screen quick-connect structure 6, which can be replaced conveniently and quickly, and a filter screen rear end detection instrument 7 is arranged on it. The cleaning mechanism 3 is composed of a cleaning brush 8, a cleaning motor 9, a moving motor 10, and a guide rail 11, which is used to clean the flying fluff and make the flying fluff separate from the filter screen 2, and can move up and down along the guide rail 11. The collecting mechanism 4 is composed of a U-shaped collecting trough 12, a collecting manifold 13, a collecting main pipe 14, a connecting hose 15, a collecting box 16, a collecting bag 18, a collecting detector 17, a negative pressure fan 19, etc.; a toothed baffle 12-1 is provided on the U-shaped collecting trough 12 to prevent the flying catkins on the cleaning brush 8 from staying in the U-shaped collecting trough 12; the collecting main pipe 14 and the collecting box 16, and the collecting box 16 and the negative pressure fan 19 are connected by a connecting hose 15 to form a passage.

[0023] When the device is not in operation, the cleaning mechanism 3 is located at the top / bottom of the deflocculation device support 1;

[0024] Working unit: the cleaning motor 9 in the cleaning mechanism 3 works, driving the cleaning brush 8 in the cleaning mechanism 3 to rotate, and at the same time the negative pressure fan 19 in the collecting mechanism 4 works to generate negative pressure; then the moving motor 10 works, driving the cleaning mechanism 3 and the collecting mechanism 4 to move along the guide rail 11, the flying fluff on the filter screen 2 is cleaned away from the filter screen 2 by the cleaning brush 8, and the flying fluff on the cleaning brush 8 is scraped away by the toothed baffle 12-1 of the U-shaped collecting groove 12 and remains in the U-shaped collecting groove 12, and then the flying fluff enters the collecting main pipe 14 along the collecting manifold 13 through the negative pressure, and finally is sucked into the collecting bag 18 through the connecting hose 15. After the moving motor 10 drives the cleaning mechanism 3 to complete the up and down movement, it returns to the initial position of the deflocculation device bracket 1, and this process is a working unit of the deflocculation device.

[0025] Working principle: When the flying flocs block the filter 2 and the value of the filter rear end detection instrument 7 reaches the cleaning setting value, the control system 5 issues a cleaning command, and the deflocculation device starts working and completes a working unit. If the value of the filter rear end detection instrument 7 does not reach the stop setting value, the deflocculation device proceeds to the next working unit; until the value of the filter rear end detection instrument 7 reaches the stop setting value, the control system 5 will issue a stop working command, and the cleaning mechanism 3 will complete the ongoing working unit along the guide rail 11, and after returning to the initial position of the deflocculation device bracket 1, the cleaning mechanism 3 and the collecting mechanism 4 will stop working.

[0026] When the value of the collection detector 17 in the collection box 16 reaches the alarm setting value, the control system 5 alarms to prompt the collection bag 18 to be cleaned.

[0027] When the deflocculation device fails, the side baffle 20 is removed, and then the filter screen 2 is quickly replaced through the filter screen quick connection structure 6 to ensure the ventilation quality and further ensure the normal operation of the ventilation system.

[0028] The innovations of this application are mainly reflected in the following aspects:

[0029] Innovation 1: Intelligent cleaning

[0030] The present invention achieves the effect of intelligent cleaning by setting a detection instrument at the rear end of the filter screen, and the control system controls the start and stop of the deflocculation device according to the setting value of the detection instrument, without a fixed cleaning frequency. In the season with high incidence of flying catkins, flying catkins will quickly accumulate on the filter screen. This design avoids the situation where the filter screen is blocked by flying catkins during the regular cleaning work interval; when flying catkins are sparse, it takes a long time for the filter screen to be covered with flying catkins. This design avoids the situation where the filter screen has not accumulated flying catkins but the device is working, thereby reducing energy consumption.

[0031] Preferably, the back-end detection instrument of the filter can be replaced with a pressure sensor, a flow sensor, a flow velocity sensor or other measurement and detection instruments;

[0032] Preferably, the number of detection instruments at the rear end of the filter can be adjusted according to actual conditions;

[0033] Innovation 2: Cleaning and collection integration

[0034] The present invention combines a cleaning brush, a U-shaped collecting trough, a collecting manifold and a collecting main pipe to form an overall mobile structure, thereby realizing the integration of cleaning and collecting. The cleaning process and the collecting process are seamlessly connected, avoiding the problem of secondary flying of the cleaned catkins during the cleaning process, and ensuring the cleaning effect of the device.

[0035] Preferably, the collection manifold mechanism can be replaced by a slit on the collection main pipe;

[0036] Preferably, the outlet of the collecting main pipe can be changed to multiple.

[0037] Innovation 3: Negative pressure collection

[0038] The present invention arranges a negative pressure fan in the collection mechanism to generate a negative pressure airflow, which drives the flying catkins into the collection bag through the collection manifold and the collection main pipe, thereby completing the collection of the catkins. The flying catkins will not accumulate in the collection trough, and the collection efficiency is high and the effect is good, thus avoiding the problem of the flying catkins being cleaned flying again during the cleaning process.

[0039] Innovation 3: Toothed baffle design

[0040] The U-shaped collecting trough of the present invention is provided with a toothed baffle, which can scrape the flying catkins on the rotating cleaning brush and leave them in the U-shaped collecting trough, thus solving the problem that the flying catkins on the cleaning brush are difficult to separate, making the catkin removal more thorough and ensuring the cleaning effect.

[0041] Preferably, the toothed baffle can be replaced with other structures that scrape and clean the flying catkins of the brush;

[0042] Preferably, the toothed baffle can be located at any position of the U-shaped collecting trough.

[0043] Innovation 5: Automatic alarm when the collection bag is full

[0044] The present invention arranges a collection detector in the collection mechanism to transmit a signal to the control system. When the set value is reached, the control system controls to issue an alarm prompt to remind the staff to clean the collection bag, thereby avoiding the situation where the staff neglects to clean the collection bag and the resulting weakening of the negative pressure suction effect, thereby improving the reliability of the device.

[0045] Preferably, the collection detector can be replaced by a pressure sensor, a flow sensor, a flow velocity sensor or other measuring and detecting instruments.

[0046] Innovation 6: Convenient filter replacement

[0047] The present invention fixes the filter on the device bracket by adopting a filter quick-connect structure. When the device fails, the side baffle is removed and the deflocculation filter is quickly replaced through the quick-connect structure to ensure ventilation quality without affecting the operation of the ventilation system, thereby greatly improving the reliability of the device.

[0048] Preferably, the filter screen quick-connect structure can be replaced by a quick-install structure, a quick-disassemble structure, etc.
