Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, and in particular to a dust-blocking device between the frames of a fully mechanized coal mining face. Background Technology

[0002] Dust pollution is a long-standing and urgent problem to be solved during coal mining operations. With the continuous expansion of coal mining scale and the continuous improvement of mining efficiency, the amount of dust generated at coal mining faces is also increasing day by day.

[0003] During coal mining, the operation of machinery and equipment, as well as the crushing and transportation of coal, generate a large amount of dust. This dust not only permeates the work area, severely deteriorating the working environment, but also poses a great threat to the health of workers. Long-term exposure to high concentrations of dust can easily lead to respiratory diseases such as pneumoconiosis, causing irreversible damage to the health and lives of workers.

[0004] Currently, the dust control methods commonly used in coal mine fully mechanized mining faces have many shortcomings. Traditional simple shielding devices, such as ordinary canvas curtains, cannot effectively block the spread of dust and lack flexibility, making it difficult to easily deploy and retract them according to actual mining needs. While some water spraying dust suppression measures can reduce the dust content in the air to a certain extent, their dust suppression effect is limited due to the lack of systematic design, and they cannot fundamentally solve the dust pollution problem.

[0005] At the same time, existing dust-blocking equipment also has shortcomings in terms of cleaning and maintenance. Most of them require frequent manual cleaning, which not only consumes a lot of manpower and resources, but also makes it difficult to guarantee the cleaning effect, causing the dust-blocking performance of the equipment to gradually decline with the increase of usage time.

[0006] Therefore, how to provide a dust-blocking device between the supports in a fully mechanized coal mining face is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] One objective of this invention is to provide a dust-blocking device between the frames of a fully mechanized coal mining face. This invention utilizes a winding roller, a servo motor, a belt drive system, and atomizing nozzles to achieve convenient opening and closing of the dust curtain and double dust blocking, thereby improving the working environment, protecting personnel health, facilitating equipment inspection and maintenance, and automatically cleaning the dust curtain through fan-shaped nozzles and cleaning brush rollers, reducing manual maintenance costs and ensuring the long-term effective use and dust-blocking performance of the dust curtain.

[0008] A dust-blocking device between the frames of a fully mechanized coal mining face according to an embodiment of the present utility model includes a storage base, a dust-blocking curtain, and a water spray pipe.

[0009] The storage base has a rotatable take-up roller inside, and the dust curtain is wound around the take-up roller with one end extending through the bottom of the storage base. A drive box is fixedly installed on one side of the rear wall of the storage base, and a servo motor is fixedly installed inside the drive box. A first pulley is driven and installed on the output shaft of the servo motor. A second pulley is fixedly installed on the outer wall of one side of the take-up roller. The first pulley and the second pulley are arranged parallel to each other, and a belt for transmission is installed on the first pulley and the second pulley. Brackets are symmetrically welded to both sides of the front wall of the storage base. Both ends of the water spray pipe are fixedly installed in the brackets, and several sets of atomizing nozzles are installed at the front end of the water spray pipe. A support is fixedly installed at the bottom of the storage base and in front of the dust curtain. A cleaning brush roller is rotatably installed in the internal groove below the support. Several sets of fan-shaped nozzles are embedded and installed above the support. A high-speed motor is fixedly installed below the side wall of the support, and the output shaft of the high-speed motor is driven and connected to the rotating shaft of the cleaning brush roller.

[0010] Furthermore, the number of atomizing nozzles is five groups, and the five groups of atomizing nozzles are evenly distributed on the outer wall of the sprinkler pipe, and each group of atomizing nozzles is connected to the sprinkler pipe.

[0011] Furthermore, several sets of water supply pipes are installed at the bottom of the sprinkler pipe, and the other end of each set of water supply pipes is connected to each set of fan-shaped spray heads.

[0012] Furthermore, the number of fan-shaped nozzles and water supply pipes are three sets, and the three sets of fan-shaped nozzles are evenly distributed on the inner side of the support, with the water outlet of each set of fan-shaped nozzles facing the dust curtain.

[0013] Furthermore, both sides of the sprinkler pipe are integrally formed with joints, and the outer walls of both sets of joints are provided with external threads.

[0014] Furthermore, the top two sides of the storage base are symmetrically fixedly welded with fixing frames, and the top of both sets of fixing frames are vertically through-holes.

[0015] Furthermore, a counterweight is fixedly installed at the bottom of the dust curtain, and the counterweight consists of an outer plastic shell and an inner counterweight iron rod.

[0016] Furthermore, the dust curtain is made of fire-resistant and anti-static canvas, which can effectively prevent safety accidents caused by sparks generated by static electricity.

[0017] The beneficial effects of this utility model are:

[0018] This utility model uses a winding roller, servo motor, and belt drive system to easily unfold and retract the dust curtain, effectively isolating dust generated during mining. In addition, it works with the atomizing nozzles on the spray pipe to achieve double dust blocking, which can greatly reduce the spread of dust in the working area, significantly improve the working environment, and protect the health of workers. The dust curtain can be raised and lowered freely, facilitating the entry and exit of workers and making it easier for the later maintenance and repair of mining equipment.

[0019] This invention achieves automatic cleaning of dust curtains through fan-shaped spray nozzles and cleaning brush rollers. Water from the sprinkler pipe is delivered to the fan-shaped spray nozzles through the water supply pipe, spraying the water in a fan shape onto the dust curtain for rinsing. At the same time, a high-speed motor drives the cleaning brush rollers to rotate and scrub the dust curtain, effectively removing dust adsorbed on the surface of the dust curtain. This ensures the long-term effective use and dust-blocking performance of the dust curtain, reducing the workload and cost of manual cleaning and maintenance. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] refer to Figure 1-4 A dust-blocking device between the frames of a fully mechanized coal mining face includes a storage base 1, a dust-blocking curtain 10, and a water spray pipe 3;

[0029] A take-up roller 14 is rotatably installed inside the storage base 1. A dust curtain 10 is wound around the take-up roller 14, and one end of the dust curtain 10 passes through the bottom of the storage base 1. A drive box 8 is fixedly installed on one side of the rear wall of the storage base 1. A servo motor 20 is fixedly installed inside the drive box 8. A first pulley 13 is driven on the output shaft of the servo motor 20. A second pulley 15 is fixedly installed on one side of the outer wall of the take-up roller 14. The first pulley 13 and the second pulley 15 are arranged parallel to each other. A belt 16 for transmission is installed on the first pulley 13 and the second pulley 15.

[0030] The dust curtain 10 has a counterweight 11 fixedly installed at the bottom, and the counterweight 11 consists of an outer plastic shell and an inner counterweight iron rod.

[0031] Secondly, the top two sides of the storage base 1 are symmetrically fixedly welded with fixing brackets 6, and the top of both sets of fixing brackets 6 are vertically through-holes 7.

[0032] It should be noted that the dust curtain 10 is made of fireproof and antistatic canvas, which can effectively prevent safety accidents caused by sparks generated by static electricity.

[0033] In this embodiment, when the dust curtain 10 needs to be unfolded, the servo motor 20 is started. The servo motor 20 drives the first pulley 13 to rotate. Through the transmission action of the belt 16, the second pulley 15 drives the take-up roller 14 to rotate, thereby releasing the dust curtain 10 from the storage seat 1. After unfolding, it can play a role in isolating dust during the mining process. Since the dust curtain 10 is equipped with a counterweight 11 at the bottom, it can ensure that the dust curtain 10 can be unfolded vertically downward. The storage seat 1 can be installed on the hydraulic support using the mounting holes 7 on the fixing frame 6. The fireproof and antistatic canvas dust curtain 10 is safer and more reliable when used in the coal mine fully mechanized mining face.

[0034] refer to Figure 1 The front wall of the storage base 1 is symmetrically fixed and welded with brackets 2. The two ends of the water pipe 3 are fixedly installed in the brackets 2. Several sets of atomizing nozzles 4 are installed at the front end of the water pipe 3.

[0035] Among them, there are five sets of atomizing nozzles 4, and the five sets of atomizing nozzles 4 are evenly distributed on the outer wall of the sprinkler pipe 3, and each set of atomizing nozzles 4 is connected to the sprinkler pipe 3.

[0036] Secondly, both sides of the sprinkler pipe 3 are integrally formed with joints 9, and the outer walls of both sets of joints 9 are provided with external threads.

[0037] In this embodiment, the water spray pipe 3 is fixed to the front wall of the storage base 1 by the bracket 2. The water spray pipe 3 can be easily connected to an external water source through the connector 9. When the water source is connected, water flows into the water spray pipe 3 and is then atomized and sprayed out through five evenly distributed atomizing nozzles 4, forming an atomized area in front of the dust curtain 10, which can effectively adsorb and settle dust in the air. Combined with the dust curtain, it can effectively improve the dust blocking effect.

[0038] refer to Figure 1 and Figure 5 A support 12 is fixedly installed at the bottom of the storage base 1 and in front of the dust curtain 10. A cleaning brush roller 17 is rotatably installed in the inner groove below the support 12. Several sets of fan-shaped spray nozzles 19 are embedded in the upper part of the support 12. A high-speed motor 18 is fixedly installed below the side wall of the support 12. The output shaft of the high-speed motor 18 is connected to the rotating shaft of the cleaning brush roller 17.

[0039] Among them, several sets of water supply pipes 5 are installed at the bottom of the sprinkler pipe 3, and the other end of each set of water supply pipes 5 is connected to each set of fan-shaped spray heads 19 respectively.

[0040] Secondly, there are three sets of fan-shaped nozzles 19 and three sets of water pipes 5. The three sets of fan-shaped nozzles 19 are evenly distributed inside the support 12, and the water outlet of each set of fan-shaped nozzles 19 faces the dust curtain 10.

[0041] In this embodiment, water in the sprinkler pipe 3 is delivered to the fan-shaped spray nozzles 19 through the water supply pipe 5. The three sets of fan-shaped spray nozzles 19 spray water in a fan shape onto the dust curtain 10. Therefore, when the dust curtain 10 is retracted, it can be started to rinse the dust curtain 10. At the same time, the high-speed motor 18 is started, which drives the cleaning brush roller 17 to rotate. The cleaning brush roller 17 contacts the surface of the dust curtain 10 and brushes the dust curtain 10, which can effectively remove the dust adsorbed on the surface of the dust curtain 10 and ensure the dust blocking performance of the dust curtain 10.

[0042] Working principle: When using this inter-frame dust blocking device in a fully mechanized coal mining face, the storage base 1 is first installed between the frames through the mounting holes 7 on the fixed frame 6. When the dust curtain 10 needs to be unfolded, the servo motor 20 is started. The servo motor 20 drives the winding roller 14 to rotate through the first pulley 13, the belt 16, and the second pulley 15, so that the dust curtain 10 unfolds vertically downward under the action of the counterweight 11, thus blocking dust. At the same time, the water spray pipe 3 is connected to an external water source through the connector 9. After the water flows into the water spray pipe 3, it is atomized through the atomizing nozzle 4. The spray forms an atomized area in front of the dust curtain 10 to adsorb and settle dust. When maintenance is required or the dust curtain 10 is not needed, the servo motor 20 can reverse the direction to raise and retract the dust curtain 10. During this process, to ensure the dust-blocking performance of the dust curtain 10, water in the sprinkler pipe 3 is delivered to the fan nozzle 19 through the water supply pipe 5. The fan nozzle 19 sprays water onto the dust curtain 10 for rinsing. At the same time, the high-speed motor 18 drives the cleaning brush roller 17 to rotate and brush the dust curtain 10 to remove dust from its surface.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
