A method for protecting the equipment environment of sand and gravel system

Abstract

The present application discloses a method for protecting the environment of sand and gravel system equipment, including: a dust sensor senses dust particles in a vortex cover that can generate a vortex, a controller of the sand and gravel system dust reduction system controls the delayed power-off relay to close, so that the solenoid valve is energized to open, and the atomizing nozzle sprays atomized water, which has the effect of reducing dust in the environment of the sand and gravel system equipment. When dust is generated in the sand-making environment of the sand and gravel system equipment, the dust enters the vortex cover of the funnel through the upper and lower openings of the vortex cover to generate a vortex, and the dust sensor wrapped in the vortex cover senses the dust particles. When crosswind occurs, the vortex cover prevents the crosswind from blowing the dust particles to easily block the sensing port of the dust sensor, thereby solving the problem that the crosswind blowing the dust particles easily blocks the sensing port of the dust sensor.

Description

Technical Field

[0001] The invention relates to a method for protecting the environment of sandstone system equipment and belongs to the technical field of sandstone production. Background Art

[0002] When the machine-made sand and gravel production process system is running, the crusher and other equipment will generate dust when crushing, which will affect the environment of the sand and gravel system equipment. In order to achieve green construction, dust reduction is required in the sand and gravel production environment.

[0003] The prior art (see Chinese patent publication number CN207993073U) receives environmental dust through a dust sensor and then sprays to reduce dust. In mountainous areas with crosswinds, the crosswinds can easily block the dust sensor ports. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a method for protecting the equipment environment of a sand and gravel system.

[0005] The present invention is achieved through the following technical solutions.

[0006] The present invention provides a method for protecting the environment of sandstone system equipment, comprising:

[0007] The dust sensor senses the dust particles in the vortex cover that can generate a vortex. The controller of the sand and gravel system dust reduction system controls the delayed power-off relay to close, so that the solenoid valve is energized to open, and the atomizing nozzle sprays out atomized water, which has the effect of reducing dust in the environment of the sand and gravel system equipment.

[0008] The sand and gravel system dust reduction system comprises:

[0009] A dust sensor senses dust particles, a signal output terminal of the dust sensor is electrically connected to a signal input terminal of a controller, and the dust sensor is mounted on a support rod; a rigid pull rod is fixedly mounted on the top of the support rod, and a vortex cover is fixedly connected to the rigid pull rod.

[0010] The number of the rigid braces is three and distributed around the circumference.

[0011] The vortex cover is in a funnel shape, the bottom of the vortex cover is open to be spaced apart from the support rod, and the dust sensor is located in the middle of the support rod wrapped by the vortex cover.

[0012] The bottom of the support rod is conical.

[0013] The sand and gravel system dust reduction system also includes a water pipe for providing water, a solenoid valve is installed in the middle of the water pipe, the solenoid valve is connected to the power supply through a delayed power-off relay, and an atomizing nozzle is installed at the outlet of the water pipe.

[0014] The signal input end of the time-delay power-off relay is electrically connected to the control signal output end of the controller.

[0015] The beneficial effect of the present invention is that when dust is generated in the sand-making environment of the sand and gravel system equipment, the dust enters the vortex cover through the upper and lower openings of the vortex cover and generates a vortex in the vortex cover of the funnel. The dust sensor wrapped in the vortex cover senses the dust particles. When crosswind occurs, the vortex cover prevents the crosswind from blowing the dust particles to block the sensing port of the dust sensor, thereby solving the problem that the crosswind is likely to block the sensing port of the dust sensor.

[0019] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0020] like Figure 1 to Figure 2 shown.

[0021] A method for protecting the environment of a sand and gravel system equipment in the present application includes:

[0022] The process of using the sand and gravel system dust reduction system to protect the sand and gravel system equipment environment from dust.

[0023] The sand and gravel system dust reduction system comprises a water pipe 1 for providing water, a solenoid valve 2 is installed in the middle of the water pipe 1, the solenoid valve 2 is connected to a power source through a delayed power-off relay 3, and an atomizing nozzle 4 is installed at the outlet of the water pipe 1.

[0024] The signal input end of the delayed power-off relay 3 is electrically connected to the control signal output end of the controller 5 .

[0025] The sand and gravel system dust reduction system also includes a dust sensor 6 for sensing dust particles, the signal output end of the dust sensor 6 is electrically connected to the signal input end of the controller 5, and the dust sensor 6 is installed on the support rod 7; a rigid pull bar 71 is fixedly installed on the top of the support rod 7, and there are three rigid pull bars 71 distributed circumferentially, and the rigid pull bars 71 are fixedly connected to a vortex cover 8; the vortex cover 8 is funnel-shaped, and the bottom of the vortex cover 8 is an opening to be spaced from the support rod 7. The dust sensor 6 is located in the middle of the support rod 7 wrapped by the vortex cover 8.

[0026] The bottom of the support rod 7 is conical, so it is easy to insert into the soil for fixation.

[0027] When dust is generated in the sand-making environment of the sand and gravel system equipment, the dust enters the vortex cover 8 through the upper and lower openings of the vortex cover 8 and generates a vortex in the vortex cover 8 of the funnel. The dust sensor 6 wrapped in the vortex cover 8 senses the dust particles. When crosswind occurs, the vortex cover 8 prevents the crosswind from blowing the dust particles to block the sensing port of the dust sensor 6, thereby solving the problem that the crosswind is likely to block the sensing port of the dust sensor.

[0028] The dust sensor 6 transmits the signal obtained by sensing the dust particles to the controller 5, and the controller 5 controls the delayed power-off relay 3 to close, so that the solenoid valve 2 is energized to open, and the atomizing nozzle 4 sprays out atomized water, which has the effect of reducing dust in the environment of the sand and gravel system equipment and protects the construction environment from being disturbed by dust. Since the dust generates a vortex in the vortex cover 8 and will hover for a certain period of time, the delayed power-off relay 3 delays the disconnection of the power supply of the solenoid valve 2, so as to achieve a better spray dust reduction effect under the low-density dust state of the sand and gravel system equipment environment.

[0029] The dust sensor 6 and the atomizing nozzle 4 can be installed at multiple points in the machine-made sand and gravel environment.
