Description

Technical Field

[0001] The utility model relates to the field of construction waste treatment, in particular to a mobile dust collecting device for a jaw crusher. Background Art

[0002] In urban construction, the generation of construction waste is inevitable. When dealing with construction waste, a crusher is needed to crush large-volume construction waste multiple times before recycling it. Common crushers include jaw crushers and cone crushers. The jaw crusher consists of two jaw plates, a movable jaw and a static jaw, to form a crushing chamber, which simulates the movement of the two jaws of an animal to complete the material crushing operation. It is mainly used as a coarse crusher and a medium crusher. When the jaw crusher commonly used in the domestic construction waste treatment industry is used, large pieces of construction waste such as sieved stones are transported to the top entrance of the jaw crusher and put into the jaw crusher. After being crushed by the jaw crusher, it is output from the bottom. Jaw crushers generate a lot of dust during crushing and discharging. For dust capture, considering the cost and difficulty of construction, the common practice in the industry is to set a suspended collection hood just above the construction waste inlet on the top of the jaw crusher. However, in actual use, this suspended collection hood has the following problems: 1. The suspension between the collection hood and the jaw crusher greatly weakens the dust suction power of the collection hood, resulting in increased air suction volume and energy consumption during operation, and a negative impact on the dust suction effect; 2. When there are bridging, jamming and other faults in the jaw crusher, a crane is required for maintenance, and the collection hood must be removed. However, the suspended collection hood is usually large in size and weight, and it is difficult to install and reset once it is dismantled. Summary of the invention

[0003] The utility model is a mobile dust collecting device for a jaw crusher, which is proposed to solve the problems of large air suction volume, high energy consumption and inconvenience of large-scale maintenance of the suspended dust collecting hood currently used for the jaw crusher.

DETAILED DESCRIPTION

[0025] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed description is given in conjunction with the embodiments.

[0026] Please refer to Figure 1-Figure 3 A mobile dust collecting device for a jaw crusher comprises a slide rail 1, a collecting hood 2, a sealing curtain 3 and a suction pipe 4; the slide rail 1 is arranged on both sides of a conveyor belt 101 at the entrance of the jaw crusher 100, the collecting hood 2 comprises a collecting port 21 and a suction port 22, the edge of the collecting port 21 is mounted on the slide rail 1, the suction port 22 is detachably connected to the suction pipe 4, and a sealing curtain 3 is further arranged around the collecting port 21, the tail end of the sealing curtain 3 is freely hanging and encloses a closed space between the collecting hood 2, the slide rail 1 and the jaw crusher;

[0027] The capture hood 2 slides along the slide rail 1; in the first use state of the capture hood 2, the capture hood 2 moves to the inlet of the jaw crusher 100 and seals and covers the top of the inlet of the jaw crusher 100; in the second use state of the capture hood 2, the capture hood 2 moves to the side of the inlet of the jaw crusher 100 and opens the inlet of the jaw crusher 100.

[0028] The mobile dust collecting device of the utility model is used for a jaw crusher 100. The inlet of the jaw crusher 100 is usually located at the top of the jaw crusher 100. A conveyor belt 101 which moves obliquely upward is provided beside the inlet to transport the construction waste from the bottom to the top. After being put into the jaw crusher 100 from the inlet, the construction waste is transported out from the outlet at the bottom by the conveyor belt after being crushed. When using the mobile dust collecting hood 2 of the utility model, firstly, slide rails 1 are arranged on both sides of the conveyor belt 101 at the entrance of the jaw crusher 100, and the collecting hood 2 moves along the slide rails 1. At this time, there is still a gap between the collecting hood 2 and the slide rails 1. Therefore, a sealing curtain 3 is installed around the collecting port 21 at the bottom end of the collecting hood 2, which can completely seal the positions where the gaps may appear at the bottom end of the collecting hood 2, and at the same time will not affect the transportation of stones; the top suction port 22 of the collecting hood 2 is connected to the suction pipe 4, and the suction pipe 4 can be connected to other suction power devices, such as fans, to provide negative pressure suction wind force in the collecting hood 2, so that all dust within the sealed coverage range of the collecting hood 2 is captured and sucked.

[0029] First, the dust collection device of the utility model is designed and constructed according to the structural characteristics of the jaw crusher 100 itself. The entrance of the jaw crusher 100 is set at the top, and a conveyor belt 101 is set next to the entrance. There is a large unobstructed space directly above the entrance and directly above the side conveyor belts 101. Therefore, the slide rails 1 can be directly set on both sides of the conveyor belt 101 without the need to build additional high-altitude brackets. At the same time, the inclination angle of the slide rails 1 is consistent with the conveyor belt 101, which can also ensure that the collection hood 2 is perfectly covered above the construction waste when moving, avoiding bumps and scratches caused by inconsistent heights with the conveyor belt 101. Therefore, the dust collection device of the utility model is relatively easy to build and has a relatively low construction cost, and is suitable for all current jaw crushers 100 with entrances on the top.

[0030] Secondly, the traditional fixed and suspended collection hood 2 needs to be disassembled and carried down piece by piece by large machinery during major maintenance, and it is difficult to reinstall and reset after maintenance. Each major maintenance is equivalent to a complete dismantling and construction project, which is time-consuming and labor-intensive. However, the dust collection device of the utility model sets the collection hood 2 as a mobile structure. When the collection hood 2 needs to be removed to open the entrance for major maintenance, it is not necessary to disassemble the collection hood 2 and carry it separately, but only needs to quickly disassemble and separate the suction port 22 of the collection hood 2 and the suction pipe 4, and then move the collection hood 2 as a whole along the slide rail 1 to the side of the entrance. During the movement, the collection hood 2 is still intact, and after the later maintenance is completed, it can be directly moved along the slide rail 1 to the top of the jaw crusher 100 entrance, and the suction port 22 can be aligned with the suction pipe 4 and reinstalled. The whole process does not require large-scale lifting and dismantling machinery, which saves time and effort, and can be used repeatedly.

[0031] Thirdly, when the dust collecting device of the utility model is in the state of collecting dust, it does not need to be suspended in the air to leave a small space for observation and maintenance, and is directly covered with a seal on the inlet of the jaw crusher 100. Therefore, it is closer to the dust source, and the dust at the inlet is completely confined in the enclosed space covered by the collecting hood 2, so the dust capturing effect is better and the dust escape can be effectively prevented. At the same time, the sealed collecting space makes it possible to achieve the same dust collecting effect with less suction wind force and lower energy consumption, thereby improving work efficiency and reducing use costs.

[0032] In one embodiment, a pulley 23 is installed on the collection port 21, and the collection cover 2 slides on the slide rail 1 through the pulley 23, so that the collection cover 2 can be moved more easily and labor-savingly, which is convenient for the staff to operate, and the installation method between the pulley 23 and the slide rail 1 is lower in cost and more convenient for maintenance.

[0033] In one embodiment, the mobile dust collection device of the utility model further includes a locking mechanism 5, which is mounted on the collection hood 2 or on the slide rail 1, and is used to fix the collection hood 2 at any position of the slide rail 1. Since the collection hood 2 is directly mounted on the jaw crusher 100, the jaw crusher 100 itself will vibrate strongly when working, causing the collection hood 2 to jump on the slide rail 1, thereby affecting the sealing effect and causing the risk of the collection hood 2 derailing. After adding the mechanism, the jumping problem of the collection hood 2 can be effectively solved.

[0034] In a more preferred embodiment, the locking mechanism 5 is a mechanical lock, which is installed on the capture port 21 and locked on the slide rail 1, or the mechanical lock is installed on the slide rail 1 and locked on the capture port 21. Since the capture cover 2 itself is large in size and weight, the use of a mechanical locking structure can effectively ensure the locking safety and avoid locking failure caused by power failure or other faults. Similarly, other locking devices can also be matched, such as using a self-locking pulley 23, adding an electronic locking structure and connecting it to a central control device for control, etc.

[0035] Furthermore, when the mechanical lock is installed on the slide rail 1, the number of mechanical locks is at least two sets, one of which is installed at the position of the slide rail 1 corresponding to the jaw crusher entrance, and the other is installed at the position of the slide rail 1 corresponding to the side of the jaw crusher entrance, so that the capture hood 2 can be effectively fixed in both the state of covering the jaw crusher entrance and moving to the side of the jaw crusher entrance. Mechanical locks can also be added at other positions according to actual conditions, thereby increasing the fixing points of the capture hood 2 on the slide rail 1. The mechanical lock can be any high-strength mechanical lock of suitable size and easy to install on the market, which can be a variety of locking methods such as buckle, latch, screw, winding, etc.

[0036] In one embodiment, a limit plate 6 is provided at one end of the slide rail 1 away from the entrance of the jaw crusher 100, and the collection hood 2 slides down along the slide rail 1 until it abuts against the limit plate 6 and stops. Since the entrance of the jaw crusher 100 itself is at the top, an inclined conveyor belt 101 is provided beside the entrance, and the slide rail 1 is provided on both sides along the conveyor belt 101, the slide rail 1 is also in an inclined state, and when the collection hood 2 moves on the slide rail 1, if the control is wrong, it is easy to slide down along the slide rail 1, and the collection hood 2 itself is heavy and has a large inertia. If it slides down to a lower height, the huge collection hood 2 will collide with other equipment or even staff, and even fall off the slide rail 1, resulting in serious consequences. Therefore, a limit plate 6 is provided on the slide rail 1, and the position and height of the limit plate 6 can be set according to actual conditions, which can effectively avoid the above-mentioned situation of the collection hood 2 being out of control and improve the safety of use.

[0037] In one embodiment, a camera is provided inside the capture hood 2, and the camera is connected to an external host and a display signal, and can transmit the working picture of the jaw crusher 100 inside the capture hood 2 in real time, so that the staff can view it conveniently, and can obtain relevant information in time when a fault occurs, which is convenient for maintenance. The signal of the camera can be transmitted to a mobile device, such as a mobile phone, a tablet, etc., through a central control device, so as to facilitate remote viewing.

[0038] Furthermore, an observation window 24 and an inspection door 25 are provided on the collection hood 2. The observation window 24 can help the staff to directly view the general internal condition of the jaw crusher 100, and the inspection door 25 can be opened when a small fault occurs inside the jaw crusher 100, so that the maintenance personnel can reach into the equipment through the inspection door 25 to carry out small inspections and maintenance, which is low-cost but easy to use.

[0039] In a preferred embodiment, the suction pipe 4 is formed by connecting multiple pipe sections together. If a major overhaul is required, the suction pipe 4 can be easily disassembled and can be quickly disassembled to leave operating space when a crane is needed for the major overhaul.

[0040] In a preferred embodiment, please refer to Figure 4 The sealing curtain 3 includes a plurality of curtain pieces 31, the top of which is fixed to the edge of the collection port 21, and the bottom of which is freely hanging down to connect with the jaw crusher or the slide rail 1. When the stones and other construction waste on the conveyor belt 101 are transported to the location of the collection hood 2, the sealing curtain 3 can be directly pushed open to enter the covering area of ​​the collection hood 2. The sealing curtain 3 is composed of a plurality of curtain pieces 31, so it is easy to be pushed open by the stones. When the construction waste is transported, the curtain pieces 31 of the sealing curtain 3 will fall down and close together under the action of gravity, so that the collection hood 2 returns to a sealed state, so that the area covered by the collection hood achieves a good sealing effect as a whole, effectively capturing dust and preventing dust from escaping.
