DETAILED DESCRIPTION
[0025] The present invention will be further described below in conjunction with the accompanying drawings.
[0026] The orientations mentioned in this specification are based on the orientation of the intelligent rapid tunneling device for high-level rock strata with coordinated dust removal of the present invention during normal operation, and do not limit the orientation during storage and transportation. They only represent relative position relationships, not absolute position relationships.
[0027] Embodiment 1:
[0028] like Figure 1 , Figure 2 and Figure 3 As shown together, an intelligent rapid excavation device for high-level rock tunnels with coordinated dust removal includes a machine body 1, a spray dust removal device 2 installed on the machine body 1, an electrostatic dust removal device 3 and a control system.
[0029] The spray dust removal device 2 includes a water storage device 21 fixed on the machine body 1, a nozzle 22 installed on the machine body 1 and spraying in the direction of the tunneling head, and a water pipeline and a water pressure regulating device connecting the nozzle 22 and the water storage device 21. The signal of the water pressure regulating device is connected to the control system.
[0030] The water storage device 21 is installed inside the tunnel boring machine to store the clean water for spraying to ensure that the spray dust suppression device has sufficient water supply. The water storage device 21 is made of corrosion-resistant and pressure-resistant materials, such as stainless steel or high-density polyethylene (HDPE), and is equipped with a water level indicator to prevent insufficient water from affecting use.
[0031] The water pipeline transports the water in the water storage device 21 to the nozzle 22. The water pipeline adopts high-strength, corrosion-resistant pipes (such as stainless steel or reinforced PVC), and the interior is smooth to reduce water flow resistance. The nozzle 22 is fixed on the tunneling rod 11, and sprays water mist in the direction of the tunneling head to achieve dust reduction effect. The nozzle 22 adopts a precision-machined atomizing nozzle to ensure that the water mist is fine and uniform. In order to achieve uniform spraying, in this embodiment, a spray pipe is arranged around the circumference of the tunneling rod 11, and a plurality of nozzles 22 are evenly installed on the circumference of the spray pipe, thereby increasing the coverage area of the spray.
[0032] The water pressure regulating device includes a dust concentration sensor 23 and a hydraulic pump which are respectively connected to the control system signal. The dust concentration sensor 23 is fixedly installed around the tunneling head, detects the dust concentration in real time, and transmits the dust concentration to the control system. The control system receives the detection signal of the dust concentration sensor 23, calculates and outputs the control signal to the hydraulic pump, and the hydraulic pump control signal adjusts the water pressure.
[0033] In order to realize real-time monitoring and feedback of water pressure, a water pressure sensor and a flow regulating valve are also provided on the water pipeline; the water flow pressure is monitored and adjusted in real time to ensure that a stable water pressure is obtained at the nozzle 22 .
[0034] When the tunneling head starts working, a large amount of dust will be generated; at this time, the spray dust removal device 2 is started, and the water in the water pipe flows through the nozzle 22 under the action of the adjusted water pressure. The nozzle 22 is specially designed to refine the water flow into tiny water mist particles; these water mist particles are sprayed towards the tunneling head at a certain angle and speed under the spraying action of the nozzle 22. After the water mist contacts the dust particles in the air, it will quickly adsorb and wrap the dust particles, increase their weight and lose their suspension ability, and then these dust particles wetted by the water mist will settle to the ground under the action of gravity. During the operation of the spray dust removal device 2, the dust concentration sensor 23 will continuously monitor the changes in dust concentration near the tunneling head. If the dust concentration is still high, the control system will further adjust the water pressure and increase the water spraying intensity; conversely, if the dust concentration sensor 23 has dropped to an acceptable range, the water pressure will be appropriately reduced to save water resources and energy consumption.
[0035] The electrostatic precipitator 3 is arranged at the front bottom of the machine body 1, and includes a discharge electrode 31 and a dust collecting electrode 32 arranged above and below, and a high-voltage power supply system arranged on the machine body 1.
[0036] The discharge electrode 31 is made of metal wire and metal plate, and is connected to the negative pole of the high-voltage power supply system; the dust collecting electrode 32 is made of metal plate and metal grid, and is connected to the positive pole of the high-voltage power supply system. A high-voltage electric field is formed between the discharge electrode 31 and the dust collecting electrode 32.
[0037] The high-voltage power supply system includes components such as a control box, a step-up transformer and a rectifier, which are used to generate and maintain the high-voltage electric field required by the discharge electrode 31 and the dust collecting electrode 32. The output voltage of the high-voltage power supply system has an important influence on the dust removal efficiency and is usually maintained at 40kV to 100kV or more to ensure effective ionization and dust capture.
[0038] Under the action of the high-voltage electric field, the discharge electrode 31 can emit a large number of electrons, ionize the surrounding gas molecules, and generate a large number of electrons and ions; these electrons and ions will move toward the two poles under the action of the electric field force; during the movement, the electrons and ions will collide with the dust particles in the airflow, causing them to be charged and deposited on the dust collecting electrode 32.
[0039] In order to avoid excessive dust on the dust collecting electrode 32, the electrostatic dust removal device 3 also includes a vibration cleaning device 4. The vibration cleaning device 4 is used to regularly remove the dust deposited on the dust collecting electrode 32 to prevent excessive dust accumulation and affect the dust removal effect. The vibration cleaning device 4 can be driven by mechanical or electromagnetic means to vibrate the dust collecting electrode 32, so that the dust falls off and falls into the dust collecting groove 321 at the bottom thereof.
[0040] The electrostatic precipitator 3 also includes a shell covering the outside of the discharge electrode 31 and the dust collecting electrode 32. The shell is installed on the body 1, and one end of the shell facing the forward direction of the body 1 is open, so as to facilitate the entry of dust. The shell adopts a steel structure, which is light and easy to install and maintain. An insulation layer is provided inside the shell to prevent thermal stress or condensation when the equipment works in a high or low temperature environment; the insulation layer usually adopts insulation cotton and a colored steel plate protective layer to ensure the stable operation of the equipment and extend its service life.
[0041] Embodiment 2:
[0042] like Figure 4 , Figure 5 and Figure 6 As shown in common, the dust collecting electrode 32 in Example 1 needs to be cleaned regularly with a low cleaning frequency, and the dust collecting electrode 32 is a flat structure, and the end located outside the opening absorbs more dust, while the inner side absorbs less dust, so its surface is not fully utilized; therefore, the dust removal effect is not good.
[0043] In this embodiment, the dust collecting electrode 32 includes a base 320 fixed to the bottom of the front end of the body 1 and located at the bottom of the discharge electrode 31, and a dust collecting groove 321 opening upward is fixedly installed on the base 320, and a dust collecting cylinder 322 is rotatably installed in the dust collecting groove 321; the dust collecting cylinder 322 is connected to the positive pole of the high-voltage power supply system. A driving device 323 for driving the dust collecting cylinder 322 to rotate is fixedly installed on the base 320; in this embodiment, the driving device 323 is a motor, and a main pulley is fixedly installed on the output shaft of the motor, and a slave pulley is fixedly installed on the central axis of the dust collecting cylinder 322, and the main pulley and the slave pulley are connected by a belt drive. In order to reduce the rotation speed of the dust collecting cylinder 322, the diameter of the main pulley in this embodiment is smaller than the diameter of the slave pulley. A vibrating and cleaning device 4 is installed in the dust collecting groove 321; the vibrating and cleaning device 4 intermittently knocks the bottom of the dust collecting cylinder 322. In this embodiment, the vibrating and dust-cleaning device 4 includes an air hammer fixedly installed in the dust collecting tank 321, and the air hammer intermittently strikes the bottom of the dust collecting cylinder 322. In actual applications, vibrating and dust-cleaning devices 4 with other structures can also be used.
[0044] When the upper surface of the dust collecting cylinder 322 absorbs enough dust, the driving device 323 drives the dust collecting cylinder 322 to rotate slowly to realize the switching of the surface of the dust collecting cylinder 322; and the side of the dust collecting cylinder 322 that absorbs the dust rotates into the dust collecting groove 321, and then the dust collecting cylinder 322 is knocked by the vibration cleaning device 4, so that the dust falls into the dust collecting groove 321, and the cleaning is realized, thereby making full use of the surface area of the dust collecting electrode 32 and improving the dust collecting effect.
[0045] When the vibrating cleaning device 4 strikes the lower surface of the dust collecting cylinder 322, in order to prevent the upper surface of the dust collecting cylinder 322 from being subjected to large vibrations and affecting its cleaning effect, the dust collecting cylinder 322 in this embodiment includes a rotating shaft 324 and a drum frame 325 rotatably mounted on the rotating shaft 324, and a plurality of arc plates 326 are mounted on the drum frame 325; all the arc plates 326 form a cylinder structure; in this embodiment, four arc plates 326 are preferably provided, and each arc plate 326 is a 1 / 4 arc structure; in actual applications, three or two plates can also be used, and this embodiment does not limit this.
[0046] In order to improve the cleaning efficiency and realize cleaning and adsorption at the same time, the arc plate 326 located above the opening of the dust collecting groove 321 in this embodiment is always in a power-on state; and the arc plate 326 located on the inner side of the dust collecting groove 321 is always in a non-power-on state; so that when cleaning the side of the dust collecting tube 322 located on the inner side of the dust collecting groove 321, it can easily shake off the dust without affecting the side of the dust collecting tube 322 located on the outer side of the dust collecting groove 321 to continue to adsorb dust.
[0047] In order to achieve this function, adjacent arc plates 326 are insulated from each other in this embodiment; the inner end surface of each arc plate 326 is provided with a conductive rod 327 extending toward the rotating shaft 324, and a conductive sheet 328 is fixed to one end of the conductive rod 327 located at the rotating shaft 324; a spring carbon brush 329 is installed on the rotating shaft 324, and the spring carbon brush 329 contacts any conductive sheet 328; the spring carbon brush 329 is electrically connected to the positive pole of the high-voltage power supply system. When the dust collecting cylinder 322 rotates, the spring carbon brush 329 can be switched to connect with different arc plates 326.
[0048] Because four arc-shaped plates 326 are preferably provided in this embodiment, two spring carbon brushes 329 are also provided, and the two spring carbon brushes 329 are always in contact with adjacent different conductive sheets 328. Of course, when two arc-shaped plates 326 are provided, only one spring carbon brush 329 is provided.
[0049] In order to facilitate the different conductive sheets 328 to smoothly contact with the spring carbon brush 329, arc-shaped transition slopes are respectively provided on both sides of the conductive sheet 328. When the conductive sheet 328 rotates around the rotating shaft 324, the transition slope first contacts with the spring carbon brush 329, and the transition slope ensures that the spring carbon brush 329 can smoothly enter the bottom of the conductive sheet 328 to form friction contact.
[0050] In order to increase the contact area between the dust and the dust collecting cylinder 322 , the opening of the dust collecting groove 321 is inclined toward the upper side of the machine body 1 .
[0051] Furthermore, a dust cleaning port is provided at the bottom of the dust collecting tank 321, and a negative pressure dust suction device is connected to the dust cleaning port. The negative pressure dust suction device can suck away the dust removed from the dust collecting cylinder 322, and at the same time generate a certain negative pressure in the dust collecting tank 321, so that more dust can float to the surface of the dust collecting cylinder 322, thereby improving the dust cleaning efficiency.
[0052] like Figure 4 , Figure 5 and Figure 6 The following is a working process of an intelligent rapid tunneling device for high-level rock tunnels with coordinated dust removal:
[0053] When the tunneling head starts to work, a large amount of dust will be generated; at this time, the spray dust removal device 2 is started, and the water in the water pipeline flows through the nozzle 22 under the action of the adjusted water pressure and sprays water mist in the direction of the tunneling head; after the water mist comes into contact with the dust particles in the air, it will quickly adsorb and wrap the dust particles, increase their weight and lose their suspension ability, and then these dust particles moistened by the water mist will settle to the ground under the action of gravity; during the operation of the spray dust removal device 2, the dust concentration sensor 23 will continuously monitor the changes in dust concentration near the tunneling head; if the dust concentration is still high, the control system will further adjust the water pressure to increase the water spraying intensity; conversely, if the dust concentration sensor 23 has dropped to an acceptable range, the water pressure will be appropriately reduced to save water resources and energy consumption. When the spray dust removal device 2 is started, the electrostatic dust removal device 3 is started, and a high-voltage electric field is generated between the discharge electrode 31 and the dust collecting electrode 32; and the driving device 323 drives the dust collecting cylinder 322 to rotate slowly, and the dust is adsorbed onto the surface of the arc plate 326, and then the arc plate 326 is transferred into the dust collecting trough 321, and the vibrating cleaning device 4 cleans the arc plate 326 in the dust collecting trough 321, thereby ensuring the dust collection effect.
[0054] The intelligent rapid tunneling device for high-level rock strata with coordinated dust removal of the present invention solves the technical problem in the prior art that a large amount of dust is generated during the operation of the tunneling machine, resulting in a poor working environment. The present invention combines spray dust removal with electrostatic dust removal to achieve efficient dust removal in the mine, thereby improving the working environment, protecting the health of workers and improving construction efficiency.
[0055] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
