Description

Technical Field

[0001] This utility model relates to the technical field of coal storage facilities and is a dust suppression device for air-supported coal sheds. Background Technology

[0002] In recent years, with increasing environmental awareness and stricter requirements from enterprises for coal mining and storage environments, air-supported membrane coal sheds, as a modern coal storage facility, have been widely used. Air-supported membrane coal sheds are characterized by their simple structure, low cost, and portability. They can also effectively protect coal from adverse environmental factors such as atmospheric moisture, rainfall, and ultraviolet radiation by controlling the internal pressure of the air membrane.

[0003] During the coal truck's journey out of the coal yard, the tire treads carry coal sludge and coal dust, which accumulate at the coal yard exit. This requires continuous cleaning by sweepers, which involves a large cleaning area and high labor intensity. The vehicles also generate dust during their journey, polluting the surrounding environment. Furthermore, some coal dust will fall onto the outer top of the air-supported coal shed with the air, which over time will cause the outer side of the air-supported coal shed to turn blackish-gray.

[0004] In existing technologies, air-supported coal sheds are generally equipped with spray systems to reduce dust inside the shed and ensure that the working environment inside meets standards. However, effective dust removal and cleaning cannot be carried out on the outside of the air-supported coal shed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a dust suppression device for air-supported coal sheds, so as to effectively remove dust and clean the outer surface of the air-supported coal shed.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A dust suppression device for air-supported coal sheds includes a connecting seat and multiple sets of arched frames; The connecting seats are fixed on both sides of the air-supported coal shed along its length. The two ends of each set of arched frames are connected to the connecting seats and located on the outside of the air-supported coal shed. Multiple spray heads are fixed on the arched frame, and a water supply channel communicating with the spray heads is provided inside the arched frame. A quick-connect plug is fixed at one end of the arched frame. The quick-connect plug is connected to the water supply channel and is used to connect a water supply device so as to spray and wash the outside of the air-supported coal shed through the spray heads.

[0007] The beneficial effects of this utility model are: by spraying the outside of the air-supported coal shed with spray heads on multiple sets of arched frames, the dust is effectively removed and cleaned; in addition, the design also carries out dust reduction treatment in areas outside the air-supported coal shed, reducing the dust generated by coal trucks and cleaning vehicles.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, a first slide rail is fixed on the connecting seat, and a sliding seat is fixed at both ends of each set of arched frames. A first pulley is fixed at the bottom of the sliding seat, and the first pulley is slidably connected in the first slide rail.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the sliding connection between the arched frame and the connecting seat is realized by the first slide rail and the first pulley, which can reduce the number of arched frames and clean the air-supported coal shed by moving the arched frames.

[0011] Furthermore, a drive motor is fixed inside the sliding seat. The drive motor is connected to the first pulley and is used to drive the first pulley to move along the first slide rail.

[0013] Furthermore, arched auxiliary frames are fixed at both ends of the connecting seat, and an auxiliary rod is fixed between the tops of the two sets of auxiliary frames, with the top of the arched frame suspended on the auxiliary rod.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the second pulley and the second slide rail guide the movement of the arch frame, and together with the first slide rail and the first pulley, make the displacement of the arch frame more stable.

[0017] Furthermore, the spray heads are tilted and fixed at equal intervals on the arched frame.

[0018] The beneficial effect of adopting the above-mentioned further scheme is that the arched frame is set on the outer top of the air-supported coal shed, and the inclined sprinkler heads can directly act on the air-supported coal shed.

[0019] Furthermore, the two adjacent spray heads on the arched frame are tilted in opposite directions.

[0020] The beneficial effect of adopting the above-mentioned further scheme is to expand the spraying range of each set of arched frames and improve the cleaning effect on the air-supported coal shed.

[0029] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0030] according to Figure 1 and Figure 2 As shown, this utility model provides a dust suppression device for air-supported coal sheds, including a connecting seat 1 and multiple sets of arched frames 2.

[0031] The connecting seat 1 is fixed on both sides of the air-supported coal shed along its length. The two ends of each set of arched frames 2 are connected to the connecting seat 1 and are located on the outside of the air-supported coal shed.

[0032] Multiple spray heads 5 are fixed on the arched frame 2, and a water supply channel communicating with the spray heads 5 is provided inside the arched frame 2. A quick connector 4 is fixed at one end of the arched frame 2. The quick connector 4 is connected to the water supply channel and is used to connect the water supply device so as to spray and wash the outside of the air-supported coal shed through the spray heads 5.

[0033] This utility model uses multiple sets of spray heads 5 on the arched frame 2 to spray the outside of the air-supported coal shed, effectively removing dust and cleaning it; in addition, this design also carries out dust reduction treatment for areas outside the air-supported coal shed, reducing the dust generated by coal trucks and cleaning vehicles.

[0034] Based on the above technical solution, the present invention can be further improved as follows.

[0035] Preferably, in this embodiment, a first slide rail is fixed to the connecting seat 1, and sliding seats 3 are fixed to both ends of each set of arched frames 2. A first pulley 8 is fixed to the bottom of the sliding seat 3, and the first pulley 8 is slidably connected to the first slide rail. The sliding connection between the arched frame 2 and the connecting seat 1 is achieved through the first slide rail and the first pulley 8, which reduces the number of arched frames 2 and allows for cleaning of the air-supported coal shed by moving the arched frames 2. In the prior art, air-supported coal sheds generally occupy a large area. If comprehensive external cleaning is required, multiple sets of arched frames 2 are needed to cover all external areas, resulting in relatively high time and cost during construction. Therefore, this embodiment changes the arched frame 2 and the connecting seat 1 to a sliding connection, reducing the number of arched frames 2 and achieving mobile cleaning.

[0036] Preferably, in this embodiment, a drive motor (not shown) is fixed inside the sliding seat 3. The drive motor is connected to the first pulley 8 and drives the first pulley 8 to move along the first slide rail. The sliding connection between the arched frame 2 and the connecting seat 1 is driven by the drive motor, improving the overall automation level. Since the air-supported coal shed occupies a large area, the corresponding size of the arched frame 2 is also relatively large. In this embodiment, the movement of the arched frame 2 is achieved by electric drive. At the same time, in the specific cleaning process, this embodiment can divide the air-supported coal shed into multiple areas equally. A partition is set at the end of the connecting seat 1 corresponding to each area. The arched frame 2 in this area only moves back and forth between two adjacent partitions, and the movement between each group of arched frames 2 is independent of each other. In addition, during implementation, in order to improve the overall level of intelligence, sensors or signal receivers can be installed at the partition, and a signal transmitter corresponding to the sensor or signal receiver is installed on the sliding seat 3. When the sensor or signal receiver at the partition detects the sliding seat 3, it transmits the received electrical signal to the background control system. The program in the background control system drives the drive motor in the sliding seat 3 to reverse, thereby causing the arch frame 2 to reciprocate. The program in the background control system is existing technology, and the specific program code will not be described in this utility model.

[0037] Preferably, in this embodiment, arched auxiliary frames 6 are fixed to both ends of the connecting seat 1, and an auxiliary rod 7 is fixed between the tops of the two sets of auxiliary frames 6. The top of the arched frame 2 is suspended on the auxiliary rod 7. As mentioned above, the air-supported coal shed occupies a large area, and the arched frame 2 is slidably connected to the connecting seat 1. Based on this, the stability of the arched frame 2 is somewhat problematic. To solve this problem, this embodiment uses the auxiliary frames 6 and the auxiliary rod 7 to suspend and support the arched frame 2, thereby improving its stability.

[0038] Preferably, in this embodiment, the bottom surface of the auxiliary rod 7 is provided with a second slide rail, and the extension direction of the first slide rail is consistent with the extension direction of the first slide rail; a second pulley 9 is fixed to the top of the arch frame 2, and the second pulley 9 is slidably connected in the second slide rail. The movement of the arch frame 2 is guided by the second pulley 9 and the second slide rail, and in conjunction with the first slide rail and the first pulley 8, the displacement of the arch frame 2 is made more stable.

[0039] Preferably, in this embodiment, the spray heads 5 are inclined and equidistantly fixed on the arched frame 2. The arched frame 2 is set on the outer top of the air-supported coal shed, and the inclined spray heads 5 can directly act on the air-supported coal shed.

[0040] Preferably, in this embodiment, the inclination directions of two adjacent spray heads 5 on the arched frame 2 are opposite. The spray range of the spray head 5 is normally a fan-shaped structure. In this embodiment, the spray range of each set of arched frames 2 is expanded with the arched frame 2 as the center of symmetry, thereby improving the cleaning effect on the air-supported coal shed.

[0041] Preferably, in this embodiment, the actual spraying range of the spray head 5 is mainly determined by its tilt angle and the water pressure. When the water pressure is controllable, the tilt angle of the spray head 5 needs to be set. If the tilt angle is too small, the spray direction of the spray head 5 directly corresponds to the air-supported coal shed, failing to form an effective atomized water curtain, and the spraying range is relatively small. If the tilt angle is too small, the parabola formed by the spray head 5 is relatively narrow, the water flow is vertical, the spraying range is relatively small, and there is also the possibility of the water being blown away by the airflow. Therefore, in this embodiment, the tilt angle of the spray head 5 is between 30° and 45°.

[0042] Preferably, in this embodiment, the water supply device includes a water supply pipeline 10 and a first water pump 12. The two ends of the water supply pipeline 10 are connected to a quick-connect plug 4 and a water storage tank 11, respectively. The first water pump 12 is connected to the water supply pipeline 10, and first shut-off valves 14 are connected to both sides of the first water pump 12 on the water supply pipeline 10. The first water pump 12 pressurizes the water flow, and the first shut-off valves 14 are used to shut off the water supply pipeline 10. In this embodiment, first shut-off valves 14 are provided on both sides of the first water pump 12 to ensure effective control of the water supply pipeline 10. One of the first shut-off valves 14 can be configured as a manually operated normally open valve, and the other can be configured as an electrically operated normally closed valve. When cleaning is required, the normally closed valve is opened through the background control system. When the water supply pipeline 10 malfunctions, the operator needs to close the normally open valve in a timely manner.

[0043] Preferably, in this embodiment, an auxiliary pipe 13 is connected in parallel to the water supply pipe 10. A second water pump 15 is connected to the auxiliary pipe 13, and second shut-off valves 16 are connected to both sides of the second water pump 15 on the auxiliary pipe 13. When the water supply pipe 10 malfunctions, the auxiliary pipe 13 can be activated; or when the water pressure is insufficient, both the water supply pipe 10 and the auxiliary pipe 13 can be activated simultaneously to increase the spray pressure. The two second shut-off valves 16 in the auxiliary pipe 13 can be the same as the two first shut-off valves 14 in the water supply pipe 10, or they can be two electrically operated normally closed valves that are opened only under specific circumstances by the background control system.
