Description

Technical Field

[0001] The present invention relates to the technical field of dust detection, and particularly to a dust detection device for stone processing. Background Art

[0002] The dust generated during the stone processing process will cause serious damage to the human body. Especially the free silica contained in the dust may lead to silicosis, which is a kind of pneumoconiosis with rapid progression and serious harm. Therefore, it is very necessary to detect the dust generated during the stone processing process. The purposes of the detection include evaluating whether the dust concentration exceeds the national standard and the content of free silica in the dust, so as to take corresponding protective measures to protect the health of the staff.

[0003] The published patent No. CN 217484122 U discloses a new type of dust detection device. Through the inner tube with a bending structure, the heating time of the dust gas in the heating part can be increased, the dehumidification effect on the dust gas can be improved, and the accuracy of the detection result can be improved. In order to adapt to the inner tube with the above bending structure, the specific heating mechanism is a heating wire, and the heating wire is wound around the outer wall of the heating tube. In this way, the comprehensive heating of the inner tube can be ensured, and the heating effect on the inner tube can be improved. However, the following problems still exist in the actual use of this patent:

[0004] Although the new type of dust detection device can increase the heating time of the dust gas in the heating part through the inner tube with a bending structure, improve the dehumidification effect on the dust gas, and improve the accuracy of the detection result, during the dehumidification process of the dust, the extraction amount of the dust cannot be controlled, and the drying time cannot be controlled either, thus affecting the drying effect. When conducting the detection, the gas in the gas storage chamber cannot be discharged, resulting in some dust remaining inside the gas storage chamber, thus affecting the subsequent dust detection effect.

[0005] Therefore, a dust detection device for stone processing is proposed to solve the problems raised above. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: For the dust detection device for stone processing, during the downward movement of the extraction piston, it will drive the rotating sealing block and the drying bracket to descend. Under the elastic force of the opening and closing spring, the opening and closing sliding sleeve can move relative to the opening and closing sliding rod, and at the same time drive the opening and closing rotating rod to rotate inside the opening and closing chute, so as to unfold the drying heating plate. Start the second rotating motor to drive the rotating sealing block and the drying bracket to rotate, so as to fully dry the sucked dust. Utilize the elastic force of the sealing spring to make the sealing sliding sleeve drive the sealing sliding plate and the sealing connecting rod to move. By virtue of the characteristic that the sealing rubber block is engaged with the air inlet, the air inlet can be blocked, preventing dust from entering the top of the exhaust piston during the upward movement of the exhaust piston, thus affecting the dust detection. The specific content is as follows:

[0022] 1. By setting up the drying mechanism, not only can the first rotating motor be used to drive the rotating worm to rotate, and due to the meshing connection between the rotating worm and the rotating worm gear, the extraction screw rod can threadedly rotate inside the rotating worm gear. Under the limiting action of the positioning sliding rod, the extraction piston moves inside the drying box. Under the elastic force of the valve spring inside the first one-way valve and the second one-way valve, the valve piston fits with the sealing protrusion, thus realizing the closure of the first one-way valve and the second one-way valve. Since the directions of the first one-way valve and the second one-way valve are opposite, the sealing protrusion inside the first one-way valve is set away from the drying box, and the sealing protrusion inside the second one-way valve is set close to the drying box. Therefore, when the extraction piston moves downward, the dust generated by stone processing can be sucked into the drying box. At the same time, when sucking the dust, the sealing protrusion of the second one-way valve fits with the valve piston, realizing the closure of the second one-way valve. During the downward movement of the extraction piston, it will drive the rotating sealing block and the drying bracket to descend. Under the elastic force of the opening and closing spring, the opening and closing sliding sleeve can move relative to the opening and closing sliding rod, and at the same time drive the opening and closing rotating rod to rotate inside the opening and closing chute, so as to unfold the drying heating plate. Start the second rotating motor to drive the rotating sealing block and the drying bracket to rotate, so as to fully dry the sucked dust. The water vapor generated by drying is absorbed by the dehumidifying block through the through hole. Reverse-start the first rotating motor, and the dried dust can be pressed into the detection box through the second one-way valve and the exhaust pipe. While the extraction piston moves upward, under the action of the inclined surface at the top of the opening and closing conical block, the opening and closing conical block drives the drying heating plate to contract, thus pressing the drying heating plate into the first protective cover, which can protect the drying heating plate. By controlling the descending depth of the extraction piston, the amount of dust extraction can be controlled, so as to facilitate the quantitative detection of dust and improve the accuracy of detection data;

[0023] 2. By detecting the exhaust mechanism, not only can the exhaust motor drive the sprocket transmission assembly and the exhaust double-threaded rod to rotate, enabling the exhaust thread sleeve to move relative to the exhaust double-threaded rod while driving the exhaust rotating rod to rotate, and driving the exhaust piston to move inside the detection box through the rotating support, but also the detected dust can be discharged through the third one-way valve, avoiding the influence of residual dust on subsequent detections. During the downward movement of the exhaust piston, due to the elastic force of the blocking spring, the blocking sliding sleeve drives the blocking sliding plate and the blocking connecting rod to move. Taking advantage of the characteristic that the blocking rubber block is snap-connected to the air inlet, the air inlet can be blocked, preventing dust from entering the top of the exhaust piston during the upward movement of the exhaust piston, thus affecting the dust detection. Through the characteristic that the second protective cover is threadedly connected to the detection box, the installation of the second protective cover can be realized, facilitating the protection of the dust detection probe. At the same time, the second protective cover can be removed, facilitating the maintenance and replacement of the dust detection probe. BRIEF DESCRIPTION OF THE DRAWINGS

A detection and exhaust mechanism 2 is provided on one side of the top of the drying mechanism 1, and a second protective cover 204 is provided at the bottom of the detection and exhaust mechanism 2. The drying mechanism 1 includes a drying box 101. On one side of the center of the bottom of the drying box 101, rotating brackets 102 are symmetrically installed. A first rotating motor 103 is fixedly installed on the outside of the rotating brackets 102. Among them, the output end of the first rotating motor 103 is fixedly connected to a rotating worm 104. A rotating worm wheel 105 is meshed and connected to one side of the rotating worm 104. The rotating worm wheel 105 is rotatably connected to the drying box 101. Among them, an extraction threaded rod 106 is threadedly connected inside the rotating worm wheel 105. The top of the extraction threaded rod 106 is rotatably connected to an extraction piston 107. Positioning sliding rods 108 are symmetrically installed at the bottom of the extraction piston 107. A limiting bottom plate 109 is fixedly installed at the bottom of the extraction threaded rod 106. A number of buffer springs 110 are fixedly installed on the top of the limiting bottom plate 109. The top of the buffer springs 110 is fixedly connected to a buffer ring 111. A second rotating motor 112 is fixedly installed inside the extraction piston 107. The output end of the second rotating motor 112 is fixedly connected to a rotating sealing block 113. A drying bracket 114 is fixedly installed on the top of the rotating sealing block 113. An opening and closing sliding groove 115 is opened inside the drying bracket 114. Opening and closing sliding rods 116 are fixedly installed around the inside of the opening and closing sliding groove 115. An opening and closing spring 117 is fixedly installed in the middle of the opening and closing sliding rods 116. Opening and closing sliding sleeves 118 are symmetrically installed at both ends of the opening and closing spring 117. An opening and closing rotating rod 119 is rotatably connected to the outside of the two opening and closing sliding sleeves 118. Drying heating plates 120 are rotatably connected to the ends of the two opening and closing rotating rods 119. An opening and closing conical block 121 is fixedly installed on the top of the drying heating plates 120. An opening and closing connecting rod 122 is fixedly installed on the top of the opening and closing conical block 121. A limiting sliding sleeve 123 is fixedly installed on the top of the opening and closing connecting rod 122. A limiting sliding rod 124 is slidably connected inside the limiting sliding sleeve 123. A limiting turntable 125 is fixedly installed on the outside of the limiting sliding rod 124. A through hole 126 is opened at the center position inside the limiting turntable 125. A second sealing block 127 is rotatably connected to the top of the limiting turntable 125. A dehumidifying block 128 is fixedly installed inside the second sealing block 127. A first one-way valve 129 and a second one-way valve 130 are respectively fixedly installed on both sides of the top of the drying box 101. By driving the rotation of the rotating worm 104 with the first rotating motor 103, and using the meshing connection between the rotating worm 104 and the rotating worm wheel 105, the extraction threaded rod 106 is threadedly rotated inside the rotating worm wheel 105. Under the limiting action of the positioning sliding rod 108, the extraction piston 107 moves inside the drying box 101. Under the elastic force of the valve spring 134 inside the first one-way valve 129 and the second one-way valve 130,The valve piston 135 is fitted and connected to the sealing projection 131, thereby closing the first one-way valve 129 and the second one-way valve 130. Since the directions of the first one-way valve 129 and the second one-way valve 130 are opposite, the sealing projection 131 inside the first one-way valve 129 is arranged away from the drying box 101, and the sealing projection 131 inside the second one-way valve 130 is arranged close to the drying box 101. Therefore, when the extraction piston 107 moves downward, the dust generated by stone processing can be sucked into the interior of the drying box 101. At the same time, when sucking the dust, the sealing projection 131 of the second one-way valve 130 fits with the valve piston 135 to close the second one-way valve 130.,

[0038] On one side inside both the first one-way valve 129 and the second one-way valve 130, a sealing projection 131 is fixedly installed. At one end inside the first one-way valve 129 and the second one-way valve 130 away from the sealing projection 131, a valve support 132 is fixedly installed. On one side of the valve support 132, a valve expansion link 133 is fixedly connected. The valve spring 134 is slidably connected to the outer side of the valve expansion link 133. The end of the valve spring 134 is fixedly connected to the valve piston 135. An exhaust pipe 136 is fixedly installed on the top of the second one-way valve 130. A first protective cover 137 is fixedly installed at the central position on the top of the drying box 101. During the process of the extraction piston 107 descending, it will drive the rotating plug 113 and the drying support 114 to descend. Under the elastic force of the opening and closing spring 117, the opening and closing sliding sleeve 118 can move relative to the opening and closing sliding rod 116, and at the same time drive the opening and closing rotating rod 119 to rotate inside the opening and closing chute 115, so that the drying heating plate 120 can be unfolded. Start the second rotating motor 112 to drive the rotating plug 113 and the drying support 114 to rotate, so as to fully dry the sucked dust. The water vapor generated by drying is absorbed by the dehumidifying block 128 through the through hole 126. Reverse-start the first rotating motor 103, and the dried dust can be pressed into the detection box 201 through the second one-way valve 130 and the exhaust pipe 136. While the extraction piston 107 moves upward, under the action of the inclined surface on the top of the opening and closing tapered block 121, the opening and closing tapered block 121 drives the drying heating plate 120 to contract, so that the drying heating plate 120 is pressed into the interior of the first protective cover 137, which can protect the drying heating plate 120. By controlling the descending depth of the extraction piston 107, the amount of dust extraction can be controlled, so as to facilitate the quantitative detection of dust and improve the accuracy of detection data.,

[0039] The detection exhaust mechanism 2 includes a detection box 201. An air inlet 202 is provided on one side of the bottom of the detection box 201. The air inlet 202 is fixedly connected to the exhaust pipe 136. A third one-way valve 203 is fixedly installed on the side of the detection box 201 away from the air inlet 202. The second protective cover 204 is threadedly connected to the detection box 201. A motor cover 205 is fixedly installed on one side of the top of the detection box 201. An exhaust motor 206 is fixedly installed on one side inside the motor cover 205. The output end of the exhaust motor 206 is fixedly connected to a sprocket transmission assembly 207. Exhaust double-threaded rods 208 are symmetrically connected to one side of the sprocket transmission assembly 207. Exhaust thread sleeves 209 are symmetrically and threadedly connected to both ends of the two exhaust double-threaded rods 208. The bottom of the exhaust thread sleeve 209 is rotatably connected to an exhaust rotating rod 210. The bottom of the exhaust rotating rod 210 is rotatably connected to a rotating support 211. An exhaust piston 212 is fixedly installed at the bottom of the rotating support 211. By driving the sprocket transmission assembly 207 and the exhaust double-threaded rods 208 to rotate with the exhaust motor 206, the exhaust thread sleeve 209 moves relative to the exhaust double-threaded rod 208 and drives the exhaust rotating rod 210 to rotate at the same time. The exhaust piston 212 is driven to move inside the detection box 201 through the rotating support 211, and the detected dust can be discharged through the third one-way valve 203, avoiding the influence of residual dust on subsequent detections. During the downward movement of the exhaust piston 212, due to the elastic force of the plugging spring 218, the plugging sliding sleeve 217 drives the plugging sliding plate 219 and the plugging connecting rod 220 to move. Due to the characteristic that the plugging rubber block 221 is snap-connected to the air inlet 202, the air inlet 202 can be plugged, avoiding dust entering the top of the exhaust piston 212 during the upward movement of the exhaust piston 212, thus affecting the detection of dust.

[0040] The exhaust piston 212 is slidably connected to the detection box 201. A dust detection probe 213 is fixedly installed at the center of the bottom of the exhaust piston 212. A plugging support 214 is fixedly installed on one side of the top of the exhaust piston 212. Plugging sliding grooves 215 are symmetrically provided inside the plugging support 214. A plugging sliding rod 216 is fixedly installed inside the plugging sliding grooves 215. A plugging sliding sleeve 217 is slidably connected to the outside of the plugging sliding rod 216. A plugging spring 218 is fixedly connected to one side of the plugging sliding sleeve 217. A plugging sliding plate 219 is fixedly installed at the top of the plugging sliding sleeve 217. A plugging connecting rod 220 is fixedly installed on one side of the plugging sliding plate 219. A plugging rubber block 221 is fixedly installed at the end of the plugging connecting rod 220. The plugging rubber block 221 is snap-connected to the air inlet 202. Due to the characteristic that the second protective cover 204 is threadedly connected to the detection box 201, the installation of the second protective cover 204 can be realized, facilitating the protection of the dust detection probe 213. At the same time, the second protective cover 204 can be removed, facilitating the maintenance and replacement of the dust detection probe 213.

[0041] Working principle: Before using this dust detection device for stone processing, it is necessary to first check the overall condition of the device to ensure that it can work properly. According to Figure 1 - Figure 11 As shown in the figure, first, the first rotating motor 103 drives the rotating worm 104 to rotate. By utilizing the meshing connection between the rotating worm 104 and the rotating worm gear 105, the extraction threaded rod 106 rotates internally within the rotating worm gear 105. Under the limiting action of the positioning sliding rod 108, the extraction piston 107 moves inside the drying box 101. Under the elastic force of the valve spring 134 inside the first one-way valve 129 and the second one-way valve 130, the valve piston 135 is in close connection with the sealing protrusion 131, thereby realizing the closing of the first one-way valve 129 and the second one-way valve 130. Since the directions of the first one-way valve 129 and the second one-way valve 130 are opposite, the sealing protrusion 131 inside the first one-way valve 129 is arranged away from the drying box 101, and the sealing protrusion 131 inside the second one-way valve 130 is arranged close to the drying box 101. Therefore, when the extraction piston 107 moves downward, the dust generated during stone processing can be sucked into the drying box 101. At the same time, when sucking the dust, the sealing protrusion 131 of the second one-way valve 130 is in close connection with the valve piston 135, realizing the closing of the second one-way valve 130.

[0042] Secondly, during the downward movement of the extraction piston 107, it drives the rotating plug 113 and the drying bracket 114 to descend. Under the elastic force of the opening and closing spring 117, the opening and closing sliding sleeve 118 can move relatively on the opening and closing sliding rod 116, and at the same time drives the opening and closing rotating rod 119 to rotate inside the opening and closing chute 115, and can unfold the drying heating plate 120. Start the second rotating motor 112 to drive the rotating plug 113 and the drying bracket 114 to rotate, so as to fully dry the sucked dust. The water vapor generated during drying is absorbed by the dehumidifying block 128 through the through hole 126. Reverse-start the first rotating motor 103, and the dried dust can be pressed into the detection box 201 through the second one-way valve 130 and the exhaust pipe 136. When the extraction piston 107 moves upward, under the action of the inclined surface at the top of the opening and closing tapered block 121, the opening and closing tapered block 121 drives the drying heating plate 120 to contract, so as to press the drying heating plate 120 into the first protective cover 137, and can protect the drying heating plate 120. By controlling the descending depth of the extraction piston 107, the amount of dust extraction can be controlled, so as to facilitate the quantitative detection of dust and improve the accuracy of detection data.

[0043] Finally, the exhaust motor 206 drives the sprocket transmission assembly 207 and the exhaust bidirectional threaded rod 208 to rotate, causing the exhaust threaded sleeve 209 to move relatively on the exhaust bidirectional threaded rod 208 while driving the exhaust rotating rod 210 to rotate. The exhaust piston 212 is driven to move inside the detection box 201 through the rotating support 211, and the detected dust can be discharged through the third one-way valve 203, avoiding the influence of residual dust on subsequent detections. During the downward movement of the exhaust piston 212, due to the elastic force of the blocking spring 218, the blocking sliding sleeve 217 drives the blocking sliding plate 219 and the blocking connecting rod 220 to move. Utilizing the characteristic that the blocking rubber block 221 is snap-fitted with the air inlet 202, the air inlet 202 can be blocked, preventing dust from entering the top of the exhaust piston 212 during the upward movement of the exhaust piston 212, thereby affecting the dust detection. Through the characteristic that the second protective cover 204 is threadedly connected to the detection box 201, the installation of the second protective cover 204 can be achieved, facilitating the protection of the dust detection probe 213.
