Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction, and more particularly to a spraying device in a shield machine cabin. Background Art

[0002] A shield machine is a special engineering machinery for tunnel excavation. Existing shield machines have functions such as excavating and cutting soil, transporting soil and slag, assembling tunnel linings, measuring and guiding, and correcting deviations. They involve multiple disciplines and technologies such as geology, civil engineering, mechanics, mechanics, hydraulics, electricity, control, and measurement. They must be designed and manufactured "tailor-made" according to different geological conditions, and have extremely high reliability requirements.

[0003] During operation, a lot of dust often spreads into the shield machine's chamber. In order to better reduce dust in the shield machine chamber, dust reduction operations such as spraying are required. However, there is no location for installing dust reduction equipment on the equipment in the shield machine chamber. To solve this problem, a shield machine dust reduction bracket with announcement number CN219654732U in the prior art is provided. Through the stacked staggered connection of the first support rod and the second vertical rod, the distance adjustment and fixing structure, as well as the angle tilt adjustment structure and the fixing structure, it not only achieves fixation in the complex environment of the shield machine body, but also can achieve stable spray dust reduction through this fixing method. Although the prior art can spray dust reduction in the shield machine chamber, directly spraying dust reduction in the chamber will cause high humidity in the chamber, affecting the health of workers. In addition, by spraying directly into the chamber, due to the large space in the chamber, it is easy to affect the dust reduction effect and cause serious waste of water resources.

[0004] In response to the above problems, some solutions have been provided in the prior art. For example, the Chinese invention application with publication number CN119435098A discloses a fully automatic pole-changing dust collector for a shield machine; as the first nozzle and the second nozzle rotate back and forth, the water sprayed from the first nozzle and the second nozzle can spray and clean the dust removal plate, thereby improving the dust reduction effect while reducing the loss of water resources. However, the prior art uses the dust removal plate to adsorb and filter the dust. Due to the large amount of dust in the bin, it is easy for the dust removal plate surface to have too much dust, which seriously affects the dust removal effect. In addition, the water flow after spraying will directly drive the dust into the sewage pipe, which will still cause a waste of water resources. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This solution sets up a spray assembly, and water flows through the nozzle to the spray box, so that the dust entering the spray box through the air inlet pipe can be treated by dust reduction. In the process of air flow to the spray box, the air flow will impact the impeller and drive the impeller to rotate. Then, in the process of impeller rotation, the air flow can be broken up, so that the dust in the air flow is fully in contact with the water mist, thereby improving the dust reduction effect. The water mist combined with the dust will fall downward. At this time, the filter plate can filter the dust in the water flow, and then the filtered water flow can flow to the spray plate again through the water pump, thereby realizing the recycling of water flow, which plays a role in improving the dust removal effect and reducing the loss of water resources.

[0020] (2) This solution sets a mesh plate. When the airflow moves toward the filter, the mesh plate can capture water mist and dust, while also reducing water resource loss. When the impeller rotates, the mounting ring drives the inclined block to rotate, and when the inclined block rotates, the push rod drives the mesh plate to move. Then, when the mesh plate shakes back and forth, the water droplets on the mesh plate drive the dust to break away from the mesh plate and merge with the water flow in the spray box, thereby improving the capture effect of the mesh plate and further improving the dust removal effect.

[0021] (3) This solution uses a cleaning plate. During the compression of the elastic pad, the airflow in the cavity above the elastic pad flows into the pneumatic telescopic rod through the first air pipe, causing the output end of the pneumatic telescopic rod to extend. The cleaning plate is then driven to move during the extension of the output end of the pneumatic telescopic rod. During the movement of the cleaning plate, the dust particles on the top wall of the filter are driven to move into the sedimentation box, thereby avoiding clogging of the filter and affecting the dust removal effect. There is no need for users to stop dust removal to clean the dust on the top wall of the filter, which further improves the dust removal effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 7 A shield machine chamber spray device includes a spray box 1, an air inlet pipe 2 is inserted into the side wall of the spray box 1, an exhaust port 3 is opened on the side wall of the spray box 1, and a spray assembly 4 is provided in the spray box 1;

[0042] The spray assembly 4 includes a filter plate 401 fixedly installed in the spray box 1, a water pump 402 whose input end is connected to the spray box 1 is fixedly installed on the side wall of the spray box 1, and a first water pipe 403 is connected to the output end of the water pump 402. A spray plate 404 is fixedly installed on the inner wall of the spray box 1, and nozzles 405 are evenly fixedly installed on the spray plate 404, and the end of the first water pipe 403 away from the water pump 402 is connected to the nozzle 405. A filter screen 406 for secondary filtering of dust is provided in the spray box 1, and a first cylinder 407 is fixedly installed on the top wall of the spray box 1, and a mounting ring 408 is rotatably mounted on the first cylinder 407, and an impeller 409 is fixedly mounted on the mounting ring 408.

[0043] During use, the air flow carrying dust in the bin body flows into the spray box 1 through the air inlet pipe 2. At the same time, the water pump 402 drives the water flow in the spray box 1 to pass through the first water pipe 403, the spray plate 404, and the nozzle 405 to spray into the spray box 1, so that the dust in the air flow can be combined with the water mist to achieve the effect of preliminary dust reduction. The air flow with preliminary dust reduction is filtered again through the filter screen 406, and then the filtered air flow flows to the outside through the exhaust port 3. In the process of the air flow flowing to the spray box 1, the air flow will impact the impeller 409 and drive the impeller 409 to rotate. Then, in the process of the impeller 409 rotating, the air flow can be broken up, so that the dust in the air flow is fully in contact with the water mist, thereby improving the dust reduction effect. The water mist combined with the dust will fall downwards. At this time, the filter plate 401 can filter the dust in the water flow, and then the filtered water flow can be again flowed to the spray plate 404 through the water pump 402, thereby realizing water circulation, which improves the dust removal effect and reduces water resource loss.

[0044] like Figure 2 、 Figure 4 As shown, a U-shaped mounting plate 501 is fixedly mounted on the side wall of the spray box 1, a mesh plate 502 for catching water droplets is slidably mounted on the side wall of the spray box 1, and an elastic pad 503 is installed between the mesh plate 502 and the mounting plate 501, a push rod 504 is fixedly mounted on the mesh plate 502, and an inclined block 505 is fixedly mounted on the mounting ring 408.

[0045] A sedimentation box 601 is installed on the side wall of the spray box 1, and a collection port connected to the sedimentation box 601 is provided on the spray box 1. A mounting block 602 is fixedly installed on the top wall of the filter plate 401, and a pneumatic telescopic rod 603 is installed on the mounting block 602. A cleaning plate 604 for cleaning the filter plate 401 is fixedly installed on the output end of the pneumatic telescopic rod 603. A cavity 605 is provided on the elastic pad 503, and a first air pipe 606 connected to the pneumatic telescopic rod 603 is inserted into the cavity 605.

[0046] By adopting the above technical solution, in the process of the air flow moving toward the filter 406, the mesh plate 502 can capture water mist and dust, further improving the dust reduction effect, and at the same time reducing the loss of water resources. In the process of the impeller 409 rotating, the mounting ring 408 is driven to rotate, and then the inclined block 505 is driven to rotate in the process of the mounting ring 408 rotating. In the process of the inclined block 505 rotating, it gradually contacts the push rod 504, and then the inclined surface of the inclined block 505 applies a thrust to the push rod 504. Under the action of the thrust, the push rod 504 drives the mesh plate 502 to move. At this time, the elastic pad 503 is compressed and has a tendency to recover. When the inclined block 505 is out of contact with the push rod 504, the elastic pad 503 stretches and drives the mesh plate 502 to reset. Then, in the process of the mesh plate 502 shaking back and forth, the water droplets on the mesh plate 502 drive the dust to break away from the mesh plate 502 and merge with the water flow in the spray box 1, thereby improving the capture effect of the mesh plate 502 and further improving the dust removal effect.

[0047] During the compression of the elastic pad 503, the airflow in the cavity 605 on the elastic pad 503 flows into the pneumatic telescopic rod 603 through the first air pipe 606, and causes the output end of the pneumatic telescopic rod 603 to extend. Then, during the extension of the output end of the pneumatic telescopic rod 603, the cleaning plate 604 is driven to move. During the movement of the cleaning plate 604, the dust particles on the top wall of the filter 406 are driven to move into the sedimentation box 601, thereby avoiding the blockage of the filter 406 affecting the dust reduction effect, and there is no need for users to stop dust reduction to clean the dust on the top wall of the filter 406, which further improves the dust removal effect.

[0048] like Figure 2 、 Figure 3 、 Figure 4 As shown, a sleeve 701 is fixedly mounted on the top wall of the spray box 1, a piston plate 702 is slidably mounted in the sleeve 701, a first vertical rod 703 is fixedly mounted on the bottom wall of the piston plate 702, a cleaning rod 704 is fixedly mounted on the bottom end of the first vertical rod 703, a sliding groove is provided on the mounting block 602, a push plate 705 is slidably mounted in the sliding groove, a first spring 706 is jointly installed between the push plate 705 and the sliding groove, a magnet block 707 is embedded on the push plate 705, an electromagnet 708 cooperating with the magnet block 707 is embedded on the mounting block 602, and the electromagnet 708 is electrically connected to the water pump 402, and a second air pipe 709 connected to the sleeve 701 is inserted on the sliding groove.

[0049] By adopting the above technical solution, when construction is stopped and dust reduction is not required, the electromagnet 708 is powered off. At this time, the first spring 706 contracts and drives the push plate 705 to move. During the movement of the push plate 705, the airflow in the space on the side of the push plate 705 close to the first spring 706 in the slide groove is squeezed and flows into the sleeve 701 through the second air pipe 709. Then, under the action of the airflow, the piston plate 702 drives the cleaning rod 704 to move downward through the first vertical rod 703, and during the downward movement of the cleaning rod 704, the dust on the filter 406 can be cleaned, thereby avoiding the accumulation of dust on the filter 406 affecting the dust removal effect in the warehouse, further improving the dust removal effect.

[0050] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, a baffle 801 is fixedly installed on the side wall of the push plate 705, and a water spray component 802 for cleaning the filter 406 is provided on the spray box 1.

[0051] The water spray assembly 802 includes a second cylinder 8021 fixedly mounted on the side wall of the spray box 1, and the second cylinder 8021 is rotatably matched with the mounting ring 408, a fixing rod 8022 is fixedly mounted on the mounting ring 408, an auger 8023 is fixedly mounted on the fixing rod 8022, a water storage tank 8024 is fixedly mounted on the top wall of the spray box 1, a second water pipe 8025 connected to the first cylinder 407 is inserted on the top wall of the water storage tank 8024, and the bottom wall of the piston plate 702 is fixedly mounted. A second vertical rod 8026 is provided, a water spray plate 8027 is fixedly installed on the second vertical rod 8026, a water spray chamber 8028 is provided on the water spray plate 8027, a water spray trough is provided on the side wall of the water spray chamber 8028, and a third water pipe 8029 is connected to the bottom wall of the water storage tank 8024, a connecting component 9 is provided on the spray box 1, and the third water pipe 8029 is connected to the water spray chamber 8028 through the connecting component 9, and a filter box 80210 is fixedly installed on the bottom end of the second cylinder 8021.

[0052] The connecting assembly 9 includes a horizontal groove provided on the spray box 1, a horizontal plate 901 is slidably installed in the horizontal groove, a second spring 902 is installed between the horizontal plate 901 and the horizontal groove, a vertical hole 903 connected to the third water pipe 8029 is provided on the horizontal plate 901, a fourth water pipe 904 connected to the vertical hole 903 is inserted into the water spray chamber 8028, an inclined groove 905 is provided on the horizontal plate 901, and a connecting rod 906 cooperating with the inclined groove 905 is fixedly installed on the top wall of the water spray plate 8027.

[0053] By adopting the above technical solution, during the rotation of the mounting ring 408, the auger 8023 is driven to rotate by the fixing rod 8022, and during the rotation of the auger 8023, the water in the spray box 1 is driven to flow through the filter box 80210, the second cylinder 8021, the mounting ring 408, and the first cylinder 407 to the second water pipe 8025 and the water storage tank 8024. When the piston plate 702 drives the cleaning rod 704 to move downward through the first vertical rod 703 and cleans the filter screen 406, the second vertical rod 8026 drives the water spray plate 8027 to move downward. At this time, the water in the water storage tank 8024 flows through the third water pipe 8029 and the connecting assembly 9 to the spray box 1. The water in the water chamber 8028 is sprayed through the water trough on the water spray chamber 8028 to the filter 406 being cleaned by the cleaning rod 704, effectively preventing the dust from floating again and adhering to the surface of the filter 406 again, further improving the dust removal effect, and in the process of the first spring 706 contracting and driving the push plate 705 to move, the push plate 705 drives the baffle 801 to move and disengage from the mesh plate 502. At this time, the water flow sprayed out of the water spray chamber 8028 can drive the dust to flow to the top of the filter plate 401, thereby preventing the dust from adhering to the surface of the filter 406 again, and causing the user to frequently stop the dust removal to clean the filter 406, further improving the dust removal effect.

[0054] As the water spray plate 8027 moves downward, it drives the connecting rod 906 to move downward. As the connecting rod 906 moves downward, it gradually loses contact with the inclined groove 905. At this time, the second spring 902 stretches and drives the horizontal plate 901 to move. As the horizontal plate 901 moves, it drives the vertical hole 903 to connect with the third water pipe 8029. At this time, the water flow in the water tank 8024 can flow into the water spray chamber 8028 through the third water pipe 8029, the vertical hole 903, and the fourth water pipe 904, and spray the filter screen 406 of the box 1 that is being cleaned. That is, through the cooperation of the horizontal plate 901 and the connecting rod 906, the filter screen 406 will be sprayed only when the cleaning rod 704 cleans the filter screen 406, thereby improving the dust removal effect.

[0055] like Figure 3 、 Figure 7 As shown, the cleaning rod 704 is provided with an installation groove, a rotating rod 101 is rotatably installed in the installation groove, bristles 102 are evenly fixedly installed on the rotating rod 101, a clockwork 103 is installed between the rotating rod 101 and the cleaning rod 704, a connecting rope 104 is wrapped around the rotating rod 101, and the end of the connecting rope 104 away from the rotating rod 101 is fixedly connected to the spray box 1.

[0056] By adopting the above technical solution, when the cleaning rod 704 moves downward, the cleaning rod 704 drives the rotating rod 101 to move downward, and in the process of the rotating rod 101 moving downward, the connecting rope 104 is pulled by the spray box 1 and moves outward of the cleaning rod 704, and in the process of the connecting rope 104 moving outward of the cleaning rod 704, it drives the rotating rod 101 to rotate, and then in the process of the rotating rod 101 rotating, the clockwork 103 gradually accumulates force, and in the process of the rotating rod 101 rotating, it drives the bristles 102 to rotate, and in the process of the bristles 102 rotating, the stains on the surface of the filter 406 can be cleaned, thereby ensuring that the dust can be separated from the filter 406 and combined with the water flow, further improving the dust removal effect.

[0057] like Figure 2 、 Figure 4 As shown, a vertical groove is provided on the bottom wall of the collecting port, a linkage plate 111 is slidably installed in the vertical groove, a blocking plate 112 is fixedly installed on the linkage plate 111, and a third air pipe 113 connected to the slide groove is inserted into the vertical groove.

[0058] By adopting the above technical solution, in the process of the first spring 706 driving the push plate 705 to move, the pressure in the space on the side of the push plate 705 away from the first spring 706 in the slide groove is reduced, and air is sucked from the vertical groove through the third air pipe 113, thereby forming a negative pressure in the vertical groove, and then under the action of pressure, the linkage plate 111 drives the sealing plate 112 to move upward. In the process of the sealing plate 112 moving upward, the collection port can be blocked. At this time, the user can deal with the stains in the sedimentation box 601 through the drain pipe 13 on the sedimentation box 601, which makes it easier for the user to deal with dust particles.

[0059] When the dust removal work starts, as the water pump 402 is energized, the electromagnet 708 is energized and generates an electromagnetic field. Then, under the action of the electromagnetic field, the magnet block 707 drives the push plate 705 to move and stretches the first spring 706. In the process of the movement of the push plate 705, the baffle 801 is reset. At the same time, in the process of the movement of the push plate 705, the air flow in the space on the side of the push plate 705 away from the first spring 706 in the slide groove is driven to flow into the vertical groove, and the linkage plate 111 drives the blocking plate 112 to disengage from the collection port. At the same time, the space in the slide groove on the side of the push plate 705 close to the first spring 706 is sucked in from the sleeve 701 through the second air pipe 709, and the piston plate 702 drives the first vertical rod 703 and the second vertical rod 8026 upward. When the second vertical rod 8026 moves upward, it drives the connecting rod 906 to move upward. When the connecting rod 906 moves upward, it gradually contacts the inclined groove 905 and drives the horizontal plate 901 to move along the horizontal groove through the inclined groove 905. At this time, the second spring 902 is compressed and has a tendency to recover. When the horizontal plate 901 moves, it drives the vertical hole 903 to disengage from the third water pipe 8029 again, thereby preparing for work again.

[0060] like Figure 3 As shown, a cleaning plate 12 cooperating with the bristles 102 is fixedly installed in the installation groove.

[0061] By adopting the above technical solution, when the rotating rod 101 drives the bristles 102 to rotate and clean the filter 406, the bristles 102 will hit the cleaning plate 12, and then the stains on the bristles 102 will be separated from the cleaning plate 12 under the action of inertia, thereby effectively preventing the stains adhered to the bristles 102 from adhering to the surface of the filter 406 again.

[0062] Instructions for use: When in use, the airflow in the bin that drives the dust flows into the spray box 1 through the air inlet pipe 2. At the same time, the water pump 402 drives the water flow in the spray box 1 to pass through the first water pipe 403, the spray plate 404, and the nozzle 405 to spray into the spray box 1, so that the dust in the airflow is combined with the water mist to achieve the effect of preliminary dust reduction. The airflow with preliminary dust reduction is filtered again through the filter 406, and then the filtered airflow flows to the outside through the exhaust port 3. In the process of the airflow flowing to the spray box 1, the airflow will impact the impeller 409 and drive the impeller 409 to rotate. Then, in the process of the impeller 409 rotating, the airflow can be broken up, so that the airflow The dust in the air is fully in contact with the water mist; in the process of the air flow moving toward the filter 406, the mesh plate 502 can capture the water mist and dust, and in the process of the impeller 409 rotating, the mesh plate 502 is driven to move by the mounting ring 408, the inclined block 505, and the push rod 504. Then, in the process of the mesh plate 502 shaking back and forth, the water droplets on the mesh plate 502 drive the dust to break away from the mesh plate 502 and merge with the water flow in the spray box 1; in the process of the elastic pad 503 being compressed, the air flow in the cavity 605 on the elastic pad 503 flows into the pneumatic telescopic rod 603 through the first air pipe 606, and causes the output end of the pneumatic telescopic rod 603 to extend, Then, in the process of extending the output end of the pneumatic telescopic rod 603, the cleaning plate 604 is driven to move, and in the process of moving the cleaning plate 604, the dust particles on the top wall of the filter 406 are driven to move into the sedimentation box 601; when construction is stopped and dust reduction is not required, the electromagnet 708 is powered off. At this time, the first spring 706 contracts and drives the push plate 705 to move. In the process of moving the push plate 705, the air flow in the space on the side of the push plate 705 close to the first spring 706 in the slide groove is squeezed and flows into the sleeve 701 through the second air pipe 709. Then, under the action of the air flow, the piston plate 702 drives the cleaning rod 704 downward through the first vertical rod 703. The cleaning rod 704 moves downward, and the dust on the filter 406 can be cleaned during the downward movement of the cleaning rod 704. When the piston plate 702 drives the cleaning rod 704 to move downward through the first vertical rod 703 and cleans the filter 406, the second vertical rod 8026 drives the water spray plate 8027 to move downward. At this time, the water in the water tank 8024 flows into the water spray chamber 8028 through the third water pipe 8029 and the connecting component 9, and is sprayed onto the filter 406 that has been cleaned by the cleaning rod 704 through the water spray trough on the water spray chamber 8028, effectively preventing the dust from floating again and adhering to the surface of the filter 406 again, thereby further improving the dust removal effect.As the first spring 706 drives the push plate 705 to move, the pressure in the space within the chute on the side of the push plate 705 away from the first spring 706 decreases, and air is drawn from the vertical chute via the third air pipe 113, creating a negative pressure within the chute. The pressure then causes the linkage plate 111 to move the blocking plate 112 upward. As the blocking plate 112 moves upward, the collection port is blocked. At this point, the user can remove the dirt within the sedimentation tank 601 through the drain pipe 13 on the sedimentation tank 601.
