Description

Technical Field

[0001] The present invention relates to the technical field of spray devices, and in particular to a mine-used automatic backwashing spray device. Background Art

[0002] The mine operation environment is complex. Especially during underground mining, problems such as dust, high temperature, and harmful gases are prominent. There are dust hazards, a large amount of inhalable particulate matter is generated in processes such as drilling, blasting, and transportation. Long-term exposure is likely to cause occupational diseases such as silicosis. There are high temperature and gas risks. In deep well mining, geothermal heat and mechanical heat generation lead to high temperatures. At the same time, the accumulation of gas may cause an explosion. There is a need for dust suppression. The traditional sprinkler dust suppression has low efficiency. The spray technology can adsorb dust through water mist and improve air quality.

[0003] In the early stage, most mine spray devices were fixed or manually controlled, with obvious defects. High-concentration dust and impurities easily blocked the nozzles, and frequent manual cleaning was required, which affected the continuity of operations. Fixed installation was difficult to dynamically adjust the spray range, resulting in dust suppression blind spots. Summary of the Invention

The bottom of the water inlet pipe is located between the top of the convex filter screen and the bottom of the concave filter screen, thereby extracting the filtered water and air and realizing the mixed atomization spraying of air and water.

The air and water are mixed and sprayed out through the gap between the arc-shaped diversion plate and the first diversion pipe, thereby performing atomized spraying. The arc-shaped diversion plate rotates relative to the edge of the first diversion pipe through the self-rotation of the arc-shaped rotating seat, thereby reducing the possibility of dust blockage at the spray outlet.

[0011] The present invention provides a mine-use automatic backwashing spray device, which has the following beneficial effects: 1. The mine automatic backwashing spray device is provided with an air extraction vortex fan. The air extraction vortex fan drives air to pass through the inside of the inclined air inlet, through the inside of the air extraction vortex fan, and through the intake check valve. The intake check valve guides the air into the inner wall of the filter box body, so as to send the air into the water, directly mixing dust and other impurities with the water body, thus preventing dust from entering the inside of the introduction device. The air passes through the filtering action of the arc-shaped holes and reaches the top of the convex filter net from the bottom of the convex filter net. The impurities are left below the convex filter net. The convex design of the convex filter net increases the contact area, thus extending the service time and reducing the maintenance frequency. The inclined air inlet, through its design, avoids extracting air from the bottom and side, thus reducing the probability of dust being extracted.

[0012] 2. The mine automatic backwashing spray device is provided with a concave filter net. The water body falls on the top of the concave filter net, thus filtering the water body entering the inside. The impurities are left on the top of the concave filter net, thus completing the filtration of the water body. The filtering handle is used to take out the whole filter box, thus facilitating maintenance and replacement. The flow splitting block is used to split the water body, avoiding the water body falling and hitting the plane to cause splashing and affecting the filtering effect. The concave design of the concave filter net increases the contact area between the water body and the concave filter net, thus extending the service life of the concave filter net and reducing the maintenance frequency. And the water body introduced by the water inlet joint does not directly fall on the lowest point of the concave filter net. The impurities are concentrated at the lowest point of the concave filter net under the action of gravity, thus avoiding the problem of filter blockage caused by impurity accumulation.

[0013] 3. The mine automatic backwashing spray device is provided with a water pump. The water pump drives the water inlet pipe to pump water. The partition plate inside the water inlet pipe separates water and air. Water is extracted through the bottom of the water inlet pipe, and air is extracted through the bottom of the air inlet plate, thus mixing and extracting air and water and sending them into the inside of the atomization device for diffusion. The bottom of the water inlet pipe is located between the top of the convex filter net and the bottom of the concave filter net, thus extracting the filtered water and air, and realizing the mixed atomization spraying of air and water.

[0014] 4. The mine automatic backwashing spray device is provided with a first motor. The drive shaft of the first motor drives the atomization assembly to rotate. The rotation of the atomization assembly drives the backwashing assembly to move, thus completing the multi-angle spraying of water mist. The inlet pipe guides water and air. The inclined design of the dust-proof cover reduces the possibility of dust falling on the atomization assembly, thus reducing the possibility of blockage. The T-shaped bracket enhances the support strength through the T-shaped design, thus enhancing the usability of the equipment. The backwashing assembly automatically cleans the periphery of the spray outlet of the atomization assembly, thus avoiding blockage.

[0015] 5. The mine-use automatic backwashing spray device is provided with a water outlet pipe to introduce air into the inside of the rotary joint. The air and water enter the inside of the first diversion pipe through the rotary joint, pass by the side of the first vane, reach the side of the arc-shaped diversion plate through the side of the first vane, and passively generate rotation through the arc-shaped design of the first vane and the arc-shaped diversion plate to drive the rotating pipe to rotate along the spray support. The air and water are mixed and ejected through the gap between the arc-shaped diversion plate and the first diversion pipe, thereby performing atomized spraying. And through the self-rotation of the arc-shaped rotating seat, the arc-shaped diversion plate and the edge of the first diversion pipe rotate relatively, thereby reducing the possibility of dust clogging at the spray outlet. And the pneumatic fan blade drives the air to flow, thereby spreading the coverage area of the atomized water spray.

[0016] 6. The mine-use automatic backwashing spray device is provided with a second diversion pipe. The water body and air flow through the inside of the second diversion pipe. The water body passes through the inside of the second diversion pipe, passes through the inner wall of the diversion box, and is ejected through the backwashing spray head. The backwashing spray head drives the diversion box to rotate. The rotation direction of the diversion box is opposite to the rotation direction of the arc-shaped diversion plate, so as to automatically backwash the edge of the arc-shaped rotating seat during atomized ejection, thereby performing automatic cleaning and reducing the possibility of clogging during the atomization process. At the same time, the air and water overflowing from the edge of the diversion box pass through the radian inside the arc-shaped rotating seat to synchronously clean the dust, thereby reducing the possibility of clogging.

The shunt block 505 is used to shunt the water body to avoid the water body splashing when it falls and touches the plane, which affects the filtering effect. Through the concave design of the concave filter net 503, the contact area between the water body and the concave filter net 503 is increased, so as to extend the service life of the concave filter net 503, thus reducing the maintenance frequency. And the water body introduced by the water inlet joint 6 does not directly fall on the lowest point of the concave filter net 503.
