Technical Field

[0001] The invention relates to the technical field of mining operations, and in particular to a spray cooling device for mining operations. Background Art

[0002] A mine refers to an independent production and operation unit that mines ores with a certain mining area. A mine mainly includes one or more mining workshops and some auxiliary workshops. A mining workshop is also called a pit mouth, mine shaft, or open-pit mine.

[0003] Open-pit mines are mines where the loose soil and surrounding rock covering the top of the ore body and its surroundings are stripped off, and the waste rock is transported to the spoil dump, where ore is mined directly from the exposed ore body. During the operation of open-pit mines, a large amount of dust is generated in the air, and fog cannons are generally used to spray and reduce dust and temperature. During the process of fog cannons spraying and reducing dust and temperature in open-pit mines, a high-pressure pump is used to pump external water through a water pipe to the nozzle and spray it out through the nozzle. Generally speaking, the water source for fog cannons can be tap water, groundwater, well water and other water sources. For some coastal areas or areas with water shortages, river water and other water sources are also an option.

[0059] The clean water tank 200 is divided into a filter chamber 210 and a collection chamber 250 by an inclined partition plate 240, and the filter layer assembly 220 is fixed in the filter chamber 210;

[0060] The filter layer assembly 220 includes an activated carbon filter layer 221, a sand filter element 222 and a honeycomb ceramic filter element 223 which are sequentially arranged from the water inlet end;

[0061] The cleaning assembly 230 is movably connected in the filter chamber 210;

[0062] The cleaning assembly 230 includes a return cover 231;

[0063] Scraping teeth 232 and roller brushes 233 are connected to both sides of the inner part of the circular cover 231.

A power source 237 is fixed on the circular cover 231.

[0064] Further specific description: the power source 237 adopts a hydraulic cylinder, which is fixed on the clean water tank 200, and the free end of the hydraulic cylinder can be movably inserted into the clean water tank 200 and fixedly connected to the circular cover 231; the top two sides of the clean water tank 200 are sealed with box doors, and the interior of the clean water tank 200 can be checked and inspected by opening the box doors; the scraper teeth 232 and the roller brush 233 are respectively fixed on the inner side of the circular cover 231.

[0065] Specifically, Figure 1 to Figure 2 As shown, a nozzle brush 300 is also included. A nozzle is fixed at one end of the fog cannon body 100, and the nozzle brush 300 is used to clean the nozzle;

[0066] It also includes a filter screen brush 400. A protective screen is fixed to one end of the fog cannon body 100 away from the nozzle, and the filter screen brush 400 is used to clean the protective screen.

[0067] Further specific explanation: During the actual use of the fog cannon, since it is in an open-pit mine environment for a long time, the fog cannon itself is easily blocked by dust, which affects the spraying and cooling operation, so a nozzle brush 300 and a filter brush 400 are designed; the nozzle brush 300 and the filter brush 400 are respectively connected to the two ends of the fog cannon body 100, and the nozzles and protective nets at both ends of the fog cannon body 100 are brushed and cleaned to improve the spraying and cooling effect.

[0068] Specifically, Figure 1 , Figure 2 , Figure 14 to Figure 15 , Fig.18 , Fig. 20 As shown, the fog cannon machine body 100 includes a fog cannon barrel 110, a nozzle and a protective net are respectively fixed at two ends of the fog cannon barrel 110, and the nozzle brush removal member 300 includes a T-shaped arc plate 310, the T-shaped arc plate 310 and the fog cannon barrel 110 are movably connected, and a No. 1 cleaning brush 320 is fixed on the T-shaped arc plate 310, and the No. 1 cleaning brush 320 is movably connected to the nozzle;

[0069] Further specific description: In the initial stage, the No. 1 cleaning brush 320 on the T-shaped arc plate 310 and the nozzle spacing design will not form an obstruction to the nozzle and will not affect the nozzle spraying and cooling. The No. 1 cleaning brush 320 is used to brush away dirt and dust on the nozzle.

[0070] A power assembly is fixed on the T-shaped arc plate 310 , and the power assembly is used to drive the T-shaped arc plate 310 to rotate around the fog cannon barrel 110 .

[0071] To further explain in detail: driven by the power assembly, the T-shaped arc plate 310 drives the No. 1 cleaning brush 320 to rotate around the fog cannon barrel 110 to brush the nozzle at one end of the fog cannon barrel 110.

[0072] Specifically, Figure 1 , Figure 2 , Figure 16 to Figure 17 , Fig.19 As shown, the filter screen brush removal member 400 includes a C-shaped plate 410 movably connected to one end of the fog cannon barrel 110, a second cleaning brush 420 is fixed to the inner side of the C-shaped plate 410, the second cleaning brush 420 is movably connected to the protective net, and the C-shaped plate 410 is connected to the end of the fog cannon barrel 110 in a cross-arrangement;

[0073] To further specify: the central axis of the C-shaped plate 410 and the fog cannon barrel 110 are on the same straight line.

[0074] A power component is fixed to the end of the C-shaped plate 410 , and the power component is used to drive the C-shaped plate 410 to rotate around the fog cannon barrel 110 .

[0075] To be further described in detail: driven by the power component, the C-shaped plate 410 rotates circumferentially at the end of the fog cannon barrel 110, thereby synchronously driving the No. 2 cleaning brush 420 to rotate. The No. 2 cleaning brush 420 is in contact with the protective net, thereby achieving rotational cleaning of the protective net by the No. 2 cleaning brush 420.

[0076] Specifically, Figures 1 to 3 , Figures 14 to 17 As shown, the power assembly and power components include an inner gear ring rotatably connected to the outer surface of the fog cannon barrel 110 and an outer gear ring movably arranged above the fog cannon barrel 110. The inner gear ring is meshed with the outer gear ring on the same side, and the outer gear ring is arranged on the inner side of the inner gear ring on the same side. Power parts are fixed on the outer gear ring.

[0077] Further specific description: the T-shaped arc plate 310 is fixedly connected to the outer surface of the inner gear ring on the same side, and the C-shaped plate 410 is fixedly connected to the outer surface of the inner gear ring on the same side; the power parts are all motors, the motor drives the outer gear ring to rotate slowly, the outer gear ring is meshed with the inner gear ring on the same side, and the inner gear ring rotates slowly, and the two inner gear rings respectively drive the T-shaped arc plate 310 and the C-shaped plate 410 to rotate around the fog cannon barrel 110, and then synchronously drive the No. 1 cleaning brush 320 and the No. 2 cleaning brush 420 to rotate around the fog cannon barrel 110, and brush off dust and dirt from the nozzles and protective nets at both ends of the fog cannon barrel 110; in addition, the inner gear ring and the fog cannon barrel 110 are rotatably connected. In order to maintain the stability of the inner gear ring, an annular groove can be opened on the inner gear ring, and a support rod is fixed on the fog cannon barrel 110, and the end of the support rod is slidably connected in the annular groove. On the one hand, the support rod supports the inner gear ring, and on the other hand, the sliding connection of the support rod in the annular groove does not affect the rotation of the inner gear ring.

[0078] Specifically, Figures 5 to 7 , Figure 11 to Figure 12 , Figure 21 to Figure 22As shown, the bottom end surfaces of the activated carbon filter layer 221, the sand filter element 222 and the honeycomb ceramic filter element 223 are fixedly connected to the inclined partition plate 240;

[0079] To be further explained in detail: the top surface of the activated carbon filter layer 221, the top surface of the gravel filter element 222, and the top surface of the honeycomb ceramic filter element 223 are respectively sealed and fixedly connected to the top of the inner wall of the filter chamber 210, which can enhance the filtering effect on water sources such as river water; river water and other water sources are pumped into the water purification tank 200 from the left side, and are filtered in turn through the activated carbon filter layer 221, the gravel filter element 222 and the honeycomb ceramic filter element 223. First, a large amount of impurities and silt will adhere to the activated carbon filter layer 221, and some will adhere to the gravel filter element 222. A small amount will adhere to the side of the honeycomb ceramic filter element 223 close to the gravel filter element 222. Finally, the amount adhering to the side of the honeycomb ceramic filter element 223 away from the gravel filter element 222 is very small. The impurities and silt on the activated carbon filter layer 221, the gravel filter element 222 and the honeycomb ceramic filter element 223 can be scraped off by the cleaning component 230.

[0080] There are three return-shaped covers 231, which are movably mounted on the activated carbon filter layer 221, the sand and gravel filter element 222 and the honeycomb ceramic filter element 223 respectively. Two adjacent return-shaped covers 231 are fixedly connected by a reinforcement 234. A connecting piece 235 is commonly fixed at the top of the three return-shaped covers 231, and the connecting piece 235 is fixedly connected to a power source 237.

[0081] Further specific explanation: The design of the connecting piece 235 is to further enhance the connection stability between the three circular covers 231. In addition, the connecting piece 235 adopts a long plate design, and the bottom end of the long plate is fixedly connected to the top surface of the circular cover 231. In order to facilitate the mobility of the long plate, a through groove 236 for the long plate to move through is provided on the sand and gravel filter 222. In addition, the portion of the long plate passing through the through groove 236 is smaller in width than the width of other portions, which can reduce the width of the adapted through groove 236, thereby reducing the passage of impurities and sediment.

[0082] Specifically, Figure 7 , Figure 11 to Figure 12 As shown, the bottom end of the activated carbon filter layer 221 and the bottom end of the gravel filter element 222 are both horizontally penetrated with a return port 224, the height of the return port 224 at the bottom end of the activated carbon filter layer 221 is greater than the height of the return port 224 at the bottom end of the gravel filter element 222, and triangular cones 225 are fixed at equal intervals between the top end of the inner wall of the return port 224 and the top end surface of the inclined partition plate 240, and the tip side of the triangular cone 225 faces the honeycomb ceramic filter element 223.

[0083] Further specific description: through the design of the reflux port 224, the impurities and sediments retained between the activated carbon filter layer 221, the gravel filter element 222 and the honeycomb ceramic filter element 223 can be returned to the bottom end of the inclined partition plate 240. The honeycomb ceramic filter element 223 is not provided with a reflux port 224, which is the last protection against impurities in water sources such as river water. In addition, the design of the triangular cone 225 is such that the tip of the triangular cone 225 faces the direction of the honeycomb ceramic filter element 223, and the tip of the triangular cone 225 and The contact area of ​​impurities and silt is small, and there is a gap between the triangular cones 225, which is convenient for impurities and silt to flow back from the tip from right to left. However, the contact area between the side surface corresponding to the tip of the triangular cone 225 and the impurities and silt is large, which can play a good blocking role on impurities and silt, reduce the passage of silt and impurities from left to right through the reflux port 224, and then make the impurities and silt flow back to the left side of the inclined partition plate 240, which is convenient for centralized cleaning; the top surface of the inclined partition plate 240 is from low to high from left to right.

[0084] Specifically, Figure 5 to Figure 6 , Figure 11 to Figure 12 As shown, the front and rear sides of the activated carbon filter layer 221, the gravel filter element 222 and the honeycomb ceramic filter element 223 are provided with gaps with the front and rear sides of the inner wall of the clean water tank 200, and the front and rear sides of the activated carbon filter layer 221, the gravel filter element 222 and the honeycomb ceramic filter element 223 are fixed with blocking brushes 226, and the other side of the blocking brush 226 is movably fitted and connected with the inner wall of the clean water tank 200;

[0085] Further specific description: a gap is set between the activated carbon filter layer 221, the sand and gravel filter element 222 and the honeycomb ceramic filter element 223 and the inner wall of the clean water tank 200 to facilitate the movement of the return cover 231. The blocking brush 226 is made of elastic material to block impurities. During the up and down movement of the return cover 231, the return cover 231 contacts and squeezes the blocking brush 226. After the return cover 231 moves through, the blocking brush 226 elastically returns to its original position to continue blocking impurities, thereby achieving the effect of filtering water sources such as river water.

[0086] A discharge port 280 is provided at the top of the inclined partition plate 240 near the activated carbon filter layer 221 , and a discharge sealing door 282 is hinged on the discharge port 280 . A driving source 281 is fixed between the discharge sealing door 282 and the inner wall of the clean water tank 200 .

[0087] To be further specific, the driving source 281 is a hydraulic cylinder, which is fixed to the inner wall of the clean water tank 200 , and the free end of the hydraulic cylinder is fixedly connected to the top of the discharge sealing door 282 .

[0090] Further specific explanation: a handle is provided on the switch door, and after the switch door is opened, impurities and silt can be easily discharged from the collecting chamber 250; in addition, a baffle is rotatably connected to the outer surface of the clean water tank 200, and the baffle and the switch door are slidably fitted, and the baffle can block the switch door. Before opening the switch door, the baffle is flipped upwards to not block the switch door, thereby facilitating the opening of the switch door; one end of the water inlet pipe 270 is connected to an external water source such as river water, and water from the water source such as river water is pumped into the clean water tank 200 through a water pump 271.

[0093] Further specific explanation: the design of the driving component 262 is to drive the cleaning cone 261 to move left and right in the debris collecting chamber 250, so as to clean up the impurities accumulated in the debris collecting chamber 250 in a unified manner; in addition, the driving component 262 is used to drive the cleaning cone 261 to move left and right; the driving component 262 includes a fixed plate fixed on the cleaning cone 261 and a threaded rod rotatably connected in the debris collecting chamber 250, and a limiting rod is also fixed in the debris collecting chamber 250, the limiting rod and the fixed plate are slidably connected, the limiting rod and the fixed plate are sleeve-connected, the threaded rod and the fixed plate are threadedly connected, the threaded rod and the fixed plate are sleeve-connected, and a driving part is fixed at one end of the threaded rod, and the driving part on the fixed plate adopts a motor, and the motor can drive the threaded rod to rotate in forward and reverse directions, so that under the limiting action of the limiting rod, the fixed plate drives the cleaning cone 261 to move left and right in the lateral direction.

[0094] Limiting plates are laterally fixed on both sides of the inner wall of the debris collecting chamber 250, and limiting grooves are provided on both sides of the debris removing cone 261 corresponding to the positions of the limiting plates, and the limiting plates are slidably connected in the limiting grooves.

[0095] Further specific description: The design of the limiting plate and the limiting groove is to enhance the movement stability of the debris removal cone 261.

[0096] When the spray cooling device for mining operation of the embodiment of the present application is actually used: first, water sources such as river water are added to the water tank in the working box 120, and the operation is as follows: connect the water inlet pipe 270 to the water source, open the control valve (not shown) on the connecting pipe 130, start the water pump 271, and pump the river water into the clean water tank 200 through the water inlet pipe 270, and filter it in turn through the activated carbon filter layer 221, the sand and gravel filter element 222, and the honeycomb ceramic filter element 223, and the filtering effect is sufficient, and then enter the water tank in the working box 120 through the connecting pipe 130, so as to filter the river water source and reduce the blockage of the nozzle and the water pipe by impurities;

[0097] Then, the fog cannon body 100 is started, and the high-pressure pump allows the filtered water to enter the nozzle through the water spray pipe and spray out through the nozzle to achieve spray cooling of the open-pit mine.

[0098] After the river water source is filtered, the filter layer needs to be cleaned, and the operation is as follows: start the hydraulic cylinder of the power source 237, and the free end of the hydraulic cylinder drives the connecting piece 235 to move up and down, and the connecting piece 235 also synchronously drives the reinforcement piece 234 and the return cover 231 to move up and down, and the scraping teeth 232 and the roller brush 233 on the inner side of the return cover 231 move up and down, and the roller brush 233 contacts and squeezes the sides of the activated carbon filter mesh layer 221, the sand and gravel filter element 222, and the honeycomb ceramic filter element 223, and the scraping teeth 232 scrape off the impurities and dust on the activated carbon filter mesh layer 221, the sand and gravel filter element 222, and the honeycomb ceramic filter element 223, and the impurities and sediment fall down. In order to achieve a better cleaning effect, you can An appropriate amount of clean water is added into the clean water tank 200, and impurities and silt mixed with water flow through the reflux port 224 and slide down from the inclined partition plate 240, and the hydraulic cylinder of the driving source 281 is started synchronously, and the free end of the hydraulic cylinder pushes one side of the discharge sealing door 282 to tilt downward, and the impurities and silt fall into the collecting chamber 250; the motor in the driving assembly 262 is started, and the motor drives the threaded rod to rotate. Under the limiting action of the limiting slot plate and the limiting slot, the cleaning cone 261 pushes the impurities and silt from the right side to the left side, opens the switch door on the left side, and discharges the impurities and silt. The operation is convenient, which solves the problem that the filter layer in the prior art needs to be cleaned manually, and the filter layer must be taken out and cleaned before being installed, and cannot be cleaned quickly.

[0099] When the fog cannon body 100 needs to be cleaned, the motor of the power part is started, and the outer gear ring is driven by the motor to rotate slowly. The outer gear ring is meshed with the inner gear ring on the same side, and the inner gear ring rotates slowly. The two inner gear rings respectively drive the T-shaped arc plate 310 and the C-shaped plate 410 to rotate around the fog cannon barrel 110, and then simultaneously drive the No. 1 cleaning brush 320 and the No. 2 cleaning brush 420 to rotate around the fog cannon barrel 110, and brush off dust and dirt from the nozzles and protective nets at both ends of the fog cannon barrel 110. This solves the problem that during the actual use of the fog cannon, the fog cannon itself is easily blocked by dust due to being in an open-pit mine environment for a long time, affecting the spraying and cooling operation.
