Description

Technical Field

[0001] This utility model relates to the field of coal mine cleaning machine technology, and in particular to a coal mine cleaning machine with dust reduction function. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas. Coal slime refers to the semi-solid material formed by coal powder containing water. It is a product of the coal production process. Depending on the type and formation mechanism, its properties and usability vary greatly. There are many types of coal slime with a wide range of uses. Large amounts of coal slime often accumulate underground. Currently, coal slime is manually shoveled onto mine carts and transported directly to the surface. This manual cleaning is not only labor-intensive but also inefficient, time-consuming, and costly. Cleaning machines effectively replace manual cleaning, greatly reducing labor intensity and shortening the coal slime cleaning cycle.

[0003] Existing coal mine cleaning machines generate a lot of dust when cleaning coal. Since the interior of a coal mine is relatively enclosed, the dust not only pollutes the surrounding environment but is also inhaled by workers, which can have a certain impact on their health. Utility Model Content

An air inlet pipe is connected to the air inlet end of the fan, and an air outlet pipe is connected to the air outlet end of the fan. A collection frame is inserted inside the dust collection box, and a filter plate is provided at the upper end of the collection frame. A sealing component is provided on one side of the outer wall of the dust collection box. An air inlet component is connected to the end of the outer wall of the dust collection box away from the fan. The air inlet component includes... The system includes a sleeve inserted into the outer wall of the dust collection box, an adjusting pipe inserted into the middle of the sleeve, a baffle plate at the end of the adjusting pipe away from the main body of the cleaning machine, a dust suppression component at the upper end of the main body of the cleaning machine away from the dust collection element, the dust suppression component including a water tank fixed to the outer wall of the main body of the cleaning machine, a water pump at the bottom of the water tank, a water pump outlet pipe, a water distribution tank at the upper end of the water pump outlet pipe, a dust suppression box at the lower end of the water distribution tank, several sets of nozzles connected to the lower end of the water distribution tank, and a water outlet pipe connected to the lower end of the dust suppression box.

[0008] As an improved technical solution, the collection frame and filter plate are movably inserted into the dust collection box, and the outer wall of the dust collection box has a groove that matches the collection frame and filter plate. The collection frame and filter plate can be pulled out from the inner wall of the dust collection box along the groove.

[0009] As an improved technical solution, the sealing assembly includes two sets of symmetrical slide rails fixedly disposed on the outer wall of the dust collection box. A sealing plate is movably inserted into the middle of the slide rails. A sliding sleeve is fixedly disposed on the upper end of the outer wall of the sealing plate. A sliding rod is movably inserted into the middle of the sliding sleeve. The lower end of the sliding rod is fixedly connected to the dust collection box. A spring is movably sleeved on the upper end of the sliding sleeve. The upper and lower ends of the spring are fixedly connected to the sliding rod and the sliding sleeve, respectively. The grooves opened on the outer wall of the sealing plate and the dust collection box fit together.

[0010] As an improved technical solution, the sleeve is fixedly inserted into the dust collection box, the adjusting tube is movably inserted into the sleeve, the baffle plate is movably sleeved on the outer wall of the adjusting tube, the outer wall of the adjusting tube is provided with two sets of symmetrical positioning pins, and the inner wall of the baffle plate is provided with slots that cooperate with the positioning pins.

[0011] As an improved technical solution, a fixing plate is fixedly provided at the lower end of the regulating pipe, and a cylinder is hinged to the lower end of the fixing plate.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. This utility model involves starting the fan, allowing dust to enter the dust collection box through the sleeve and regulating pipe. The dust is then filtered through a baffle plate and a filter plate to remove solid particles. The filtered dust then enters the dust settling box. Starting the water pump allows water from the tank to spray onto the dust in the settling box, dissolving the dust in the water. Wastewater is discharged from the outlet pipe. The purified gas in the settling box is then discharged through the air outlet. This system quickly absorbs dust generated during the cleaning machine's operation, preventing dust pollution of the surrounding environment and avoiding excessive dust inhalation by workers, thus protecting their health.

[0016] 2. In the dust suppression process, the cylinder can be activated, the cylinder extension end extends, and the fixing plate drives the adjusting tube to slide along the inner wall of the sleeve, thereby adjusting the length of the adjusting tube. This allows for rapid absorption of the main dust-covered areas and spaces during the dust suppression process, increasing the efficiency of dust suppression. Attached Figure Description

[0030] The collection frame 25 and the filter plate 26 are movably inserted into the dust collection box 21. The outer wall of the dust collection box 21 has a groove that matches the collection frame 25 and the filter plate 26. The collection frame 25 and the filter plate 26 can be pulled out from the inner wall of the dust collection box 21 along the groove.

[0031] The sealing assembly 27 includes two sets of symmetrical slide rails 271 fixedly disposed on the outer wall of the dust collection box 21. A sealing plate 272 is movably inserted into the middle of the slide rail 271. A sliding sleeve 274 is fixedly disposed on the upper end of the outer wall of the sealing plate 272. A sliding rod 273 is movably inserted into the middle of the sliding sleeve 274. The lower end of the sliding rod 273 is fixedly connected to the dust collection box 21.

[0032] The sleeve 31 is fixedly inserted into the dust collection box 21, the adjusting tube 32 is movably inserted into the sleeve 31, and the baffle plate 33 is movably sleeved on the outer wall of the adjusting tube 32. The outer wall of the adjusting tube 32 is provided with two sets of symmetrical positioning pins 34, and the inner wall of the baffle plate 33 is provided with slots that cooperate with the positioning pins 34.

[0033] A fixing plate 35 is fixedly provided at the lower end of the regulating pipe 32. A cylinder 37 is hinged at the lower end of the fixing plate 35. The lower end of the cylinder 37 is hinged to the outer wall of the cleaning machine body 1. A bolt 36 is threaded into the upper outer wall of the regulating pipe 32. The lower end of the bolt 36 moves through the regulating pipe 32.

[0034] The air outlet pipe 24 is connected to the dust settling box 45. Several sets of air outlet holes 48 are opened at the upper end of the dust settling box 45, and the water outlet of the nozzle 46 is located inside the dust settling box 45.

[0035] The water tank 41 has an inlet 49 at the top.

[0036] When the cleaning machine generates dust during operation, the fan 23 can be started. The dust enters the regulating pipe 32 through the baffle plate 33. The baffle plate 33 can block larger impurities in the dust, preventing them from entering the fan 23 and causing damage. The dust in the regulating pipe 32 enters the dust collection box 21 through the sleeve 31. The filter plate 26 in the dust collection box 21 blocks smaller impurities in the dust. The blocked impurities fall into the collection frame 25 for easy subsequent cleaning. The dust filtered twice by the baffle plate 33 and the filter plate 26 enters the dust settling box 4 through the exhaust pipe 24. In step 5, the water pump 42 is started to draw water from the water tank 41 into the distribution tank 44 through the water pipe 43. The water in the distribution tank 44 is sprayed out through the nozzle 46 to spray the dust entering the dust settling box 45. The dust dissolves in the water, and the wastewater is discharged from the outlet pipe 47. The purified gas entering the dust settling box 45 is finally discharged through the air outlet 48. Through the above operation, the dust generated during the operation of the cleaning machine can be quickly absorbed, avoiding dust pollution of the surrounding environment and preventing excessive dust from being inhaled by workers, thus protecting their health. During the dust settling process, the cylinder 37 can be activated. The extension end 37 extends out, and the fixing plate 35 drives the adjusting tube 32 to slide along the inner wall of the sleeve 31, thereby adjusting the length of the adjusting tube 32. This allows for rapid absorption of dust in the main covered areas and spaces during dust suppression, increasing dust suppression efficiency. After dust suppression is complete, the bolt 36 can be rotated to unscrew the upper end of the barrier plate 33, and the barrier plate 33 can be pulled out along the positioning pin 34 for easy cleaning. This prevents excessive impurities from adhering to the ventilation holes of the barrier plate 33 and affecting its ventilation effect. When it is necessary to treat the dust particles and impurities accumulated in the collection frame 25... When the slide sleeve 274 is slid upward along the slide rod 273 and the spring 275 is compressed, the sealing plate 272 moves upward along the slide rail 271. Then the collection frame 25 and the filter plate 26 are pulled out from the groove on the front outer wall of the dust collection box 21 to clean the dust particles and impurities in the collection frame 25. Then the collection frame 25 and the filter plate 26 are reinserted into the dust collection box 21, the slide sleeve 274 is released, and under the reverse elastic force of the spring 275, the sealing plate 272 slides downward along the slide rail 271 to cover the groove on the outer wall of the dust collection box 21, preventing gas from flowing out of the groove during the dust removal process.
