Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dust purification devices, in particular to a dust purification device for construction and a purification method. BACKGROUND

[0002] Dust pollution of construction engineering construction refers to the pollution of atmospheric caused by dust particles generated in the production activities such as housing construction, road and pipeline construction, house demolition, material transportation, material stacking, road cleaning and bare land.

[0003] It should be noted that in the process of dust control in the construction site, a large amount of water mist is sprayed by the fog cannon machine to reduce dust in the air. When in use, the elevation angle of the cone barrel is adjusted, high-pressure water is supplied through the water inlet pipe, and water mist is sprayed through the multiple fixed water spray heads arranged on the cone barrel. At the same time, the movable support is rotated to swing the cone barrel, and the water mist is sprayed into the air. However, since the construction site has a large amount of dust, impurities, stones and other impurities, these impurities will be condensed or blown up by the stones and impurities when they come into contact with water, which will block the water spray heads, thereby resulting in poor atomization effect. In addition, if the cone barrel fails or is operated incorrectly, the position of the cone barrel will be lowered, which will immediately spray the dust and impurities on the ground, further aggravating the pollution of the construction site.

[0025] A method for purifying dust for construction, which is carried out according to the above-mentioned dust purification device for construction, comprises the following steps:

[0026] S1. Multiple sprinkler heads are clogged, causing the water pressure in the expansion tank to continue to increase, driving the expansion plate to move. The expansion plate drives the driving rod to move through the toggle frame, and the driving rod drives a toggle rod to move, so that the toggle rod drives the rotating disk to rotate;

[0027] S2. The rotating disk rotates to drive the multiple pop-up rods to be squeezed and retracted into the pop-up slots, and the rebound springs are stressed. The rotating disk rotates to drive the next group of water spouts to align with the multiple water outlet slots, and the multiple pop-up rods are snapped into the positioning slots at the corresponding positions, switching the water heads so that the water heads at the corresponding positions start spraying water;

[0028] S3. The rotating disk drives the sprinkler head into the water outlet trough at the corresponding position. Under the rebound force of the support spring, the driving tooth plate drives the extrusion rod to move. The extrusion rod enters the water outlet trough. The driving tooth plate moves and drives the gear to rotate. The gear drives the closing cover to rotate and open through the rotating shaft, and the sprinkler head is opened for use.

[0029] S4. The cone barrel rotates downward due to a malfunction, and the cone barrel squeezes the extrusion frame to move. The extrusion frame moves in the installation cylinder through the lower pressure rod.

[0030] The beneficial effects of the dust purification device and purification method for construction proposed by the present invention are:

[0031] In the present invention, through the setting of the rotation conversion mechanism, when multiple water heads are blocked, the water pressure in the expansion tank continues to increase, so that the toggle frame moves a toggle rod through the driving rod, and the toggle rod drives the rotating disk to rotate, thereby driving multiple water heads to rotate. At the same time, the rotation of the rotating disk drives the next group of water troughs to align with multiple water outlet troughs, and enables multiple pop-up rods to be stuck in the positioning grooves at the corresponding positions, so that the water heads at the corresponding positions can discharge water, thereby completing the automatic replacement of the water heads and ensuring the continuous dust removal work.

[0032] Furthermore, in the present invention, through the provision of a protective anti-blocking mechanism, when the rotating disk drives the water sprinkler head to enter the water outlet trough at the corresponding position, under the rebound force of the supporting spring, the driving tooth plate drives the extrusion rod to move, and the extrusion rod enters the water outlet trough, and the driving tooth plate moves to drive the gear to rotate, and the gear drives the closing cover to rotate and open through the rotating shaft, so that the water sprinkler head can be opened for use. Similarly, when the water sprinkler head does not need to spray water, the water sprinkler head is sealed and protected by the closing cover, so that the water sprinkler head can be prevented from being blocked by external dust or impurities when used outdoors, further ensuring the continuous dust removal work.

[0033] Further, in the present application, by setting the compression sealing mechanism, when the device malfunctions or is operated improperly, the angle of the cone barrel driving the water jet head is downward, at this time, the cone barrel extrudes the extrusion frame to move, the extrusion frame moves in the installation cylinder through the pressing rod, and the return spring is compressed, the pressing rod moves through a switching shaft to drive the switching rod to move, the switching rod drives the moving plate to move through another switching shaft, so that the moving plate drives the sealing plate to seal the water outlet hole, the purpose of blocking water inflow is achieved, and the problem of continuous water spraying when the angle of the cone barrel is downward is avoided.
