[0002] Cone crusher is a common crushing equipment in the construction waste treatment industry. It is mainly used to crush construction waste of medium hardness and medium brittleness. The material is crushed into the required particle size through the impact of the rotating cone crushing cavity and the hammer head. A lot of dust will be generated during the use of the cone crusher. The country has strict requirements on the dust concentration in the working environment. Therefore, the cone crusher must be equipped with a dust capture device to capture dust synchronously when the cone crusher is working and reduce the dust in the working environment to below the standard concentration.

[0003] The entrance of the cone crusher is set at the top. The dust collection device currently equipped in the industry is a dust collection hood directly suspended above the entrance. There is a certain space between the collection hood and the entrance. Construction waste is put in from the top entrance and crushed and transported out from the bottom exit. At the same time, the collection hood absorbs the dust dispersed at the entrance and inside the equipment. However, a fan is installed in the middle of the cone crusher. The fan blows air into the equipment, which seriously interferes with the dust suction airflow of the top dust collection hood, resulting in high energy consumption and low efficiency of dust collection. In view of the above situation of the cone crusher, a dust collection hood is needed that can weaken the interference of the fan's lateral air supply to the inside of the equipment.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0024] Please refer to Figure 1 and Figure 2An energy-saving dust side suction hood for a cone crusher is installed on the top of the cone crusher 100. The energy-saving dust side suction hood includes a slide rail 1, a side suction collection hood 2, a sealing curtain 3, and a suction pipe 4. The slide rail 1 is arranged on both sides of a conveyor belt 102 at a top entrance 101 of the cone crusher 100. The side suction collection hood 2 is installed on the slide rail 1. The side suction collection hood 2 includes a dust inlet 201 arranged at the bottom, a feed port 202 and a suction port 203 arranged at the front and rear sides, and the feed port 202 is located at the side suction hood. The sealing curtain 3 is installed on the bottom periphery of the side suction collection hood 2 at one side of the conveyor belt 102 near the top inlet 101 of the cone crusher 100, and freely hangs on the cone crusher 100. The suction port 203 is located on the side of the side suction collection hood 2 near the top inlet 101 of the cone crusher 100. The suction port 203 is detachably connected to the suction pipe 4, and the suction pipe 4 is connected to an external negative pressure device. The external negative pressure device can be a dust removal device, etc., with a fan, which can generate a negative pressure airflow for sucking dust;

[0025] The side suction collecting hood 2 moves on the slide rail 1. When collecting dust, the side suction collecting hood 2 moves to the dust inlet 201 and covers the top inlet 101 of the cone crusher 100, and the suction pipe 4 is connected to the suction port 203. When not collecting dust, the side suction collecting hood 2 moves to the side of the top inlet 101 of the cone crusher 100, the top inlet 101 is open, and the suction port 203 and the suction pipe 4 are in a disassembled and separated state.

[0026] The use process of the energy-saving dust side suction hood protected by the utility model is as follows: when the cone crusher 100 is ready to work and needs to capture dust synchronously, the side suction collection hood 2 is moved along the slide rail 1 to the top inlet 101, and the dust inlet 201 of the side suction collection hood 2 is made to face the top inlet 101 of the cone crusher 100, the suction port 203 of the side suction collection hood 2 is connected to the suction pipe 4, and the external negative pressure device provides a negative pressure suction airflow to suck the dust inside the cone crusher 100 into the side suction collection hood 2. When the cone crusher 100 is ready for maintenance, the suction pipe 4 and the side suction collection hood 2 are disassembled and separated, and the side suction collection hood 2 is moved along the slide rail 1 to the side of the top entrance 101, so that the top entrance 101 is exposed and open, and maintenance personnel or large maintenance equipment such as cranes can enter the cone crusher 100 from the top entrance 101 for operation. After the maintenance is completed, it is only necessary to move the side suction collection hood 2 along the slide rail 1 to the top entrance 101 and connect the suction pipe 4 to the suction port 203 of the side suction collection hood 2.

[0027] The suction port of the traditional dust collection hood is located at the top, and the negative pressure airflow is sucked vertically upward. The fan of the cone crusher 100 supplies air from the outside of the equipment to the inside of the equipment, so that there is a horizontal airflow in the cavity of the cone crusher 100. The direction of this horizontal airflow is perpendicular to the vertical upward negative pressure airflow, which greatly interferes with the negative pressure suction airflow and weakens the suction force of the negative pressure airflow, thereby greatly reducing the dust collection efficiency.

[0028] The energy-saving dust side suction hood of the utility model is that firstly, the side suction collecting hood 2 is directly installed on the slide rail 1, and the slide rail 1 is directly installed on the cone crusher 100, and a sealing curtain 3 is also installed at the bottom of the side suction collecting hood 2, so that the side suction collecting hood 2 and the cone crusher 100 are not only not installed in the air, but a semi-enclosed space is formed instead, which can effectively prevent dust from escaping without affecting the conveyor belt 102 to transport construction waste, enhance the suction force of the negative pressure airflow, improve the dust collection efficiency, and effectively reduce energy consumption. Secondly, the suction port 203 of the side suction collection hood 2 is installed on the side and opposite to the feed port 202. The negative pressure airflow forms a lateral airflow in the side suction collection hood 2, which effectively avoids the lateral airflow formed by the fan inside the cone crusher 100, so that the negative pressure suction airflow can be effectively utilized, and the dust collection efficiency is effectively improved. Even the negative pressure airflow sucked from the side may be connected and merged with the lateral airflow formed by the fan, which makes the lateral airflow formed by the fan become an enhancement factor of the negative pressure suction airflow, which is beneficial to the effective collection of dust inside the cone crusher 100.

[0029] In one embodiment, the side suction collection hood 2 includes a rectangular hood 21 and a trapezoidal hood 22. The rectangular hood 21 is attached to the top conveyor belt of the cone crusher 100 and extends downward along the direction of the conveyor belt. The trapezoidal hood 22 is formed by the top surface of the rectangular hood 21 near the top inlet 101 of the cone crusher 100 being tilted downward. The side suction collection hood 2 is flat and long as a whole, which will not occupy too much space on the top of the cone crusher 100, and facilitates the dust in the side suction collection hood 2 to move horizontally inside the hood along the negative pressure suction airflow; the rectangular hood 21 is a rectangular parallelepiped, which is convenient for production on the one hand, and on the other hand, the rectangular hood 21 is attached to the top of the conveyor belt beside the top inlet 101, and a regular-shaped channel is formed between the conveyor belt to facilitate the transportation of construction waste; the trapezoidal hood 22 is formed by the top surface of the rectangular hood 21 being tilted downward. Further, the longitudinal cross-sectional area of ​​the trapezoidal hood 22 is smaller on one side away from the rectangular hood 21. The cross-sectional area becomes smaller, so the negative pressure airflow in the side suction collection hood 2 is compressed when entering the trapezoidal hood 22 from the rectangular hood 21, and the suction force is enhanced. When entering the suction port 203 from the trapezoidal hood 22, the cross-sectional area becomes further smaller, and the suction force is further enhanced, and the suction and collection force for dust is gradually enhanced.

[0030] In a preferred embodiment, the suction port 203 is arranged on the side of the trapezoidal cover body 22 away from the rectangular cover body 21, and the suction port 203 is close to the top inlet 101 of the cone crusher 100. The closer to the suction port 203, the stronger the suction force, and the better the dust suction and capture effect. Therefore, setting the suction port 203 at the above position can obtain the best dust capture effect.

[0031] Furthermore, the suction port 203 is a conical port, the end with a larger opening of the conical port is connected to the trapezoidal cover body 22, and the end with a smaller opening of the conical port is connected to the suction pipe 4. The structure of the suction port 203 allows the suction force to gradually increase during the process of dust being sent from the suction port 203 to the suction pipe 4. In addition, the end with a larger opening of the conical port can be a circular port or a flat and long port. Under the same area, the flat port has a greater negative pressure suction force than the circular port.

[0032] In one embodiment, the length and width of the side suction collection hood 2 are respectively greater than the length and width of the top inlet 101 of the cone crusher 100, ensuring that the side suction collection hood 2 can completely cover the top inlet 101, effectively preventing excessive dust from escaping from the gaps to pollute the working environment, and even if the side suction collection hood 2 shakes or shifts slightly when the cone crusher 100 is working, it will not cause a large amount of dust to escape.

[0033] In one embodiment, a pulley 23 is provided at the bottom of the side suction collection hood 2, and the pulley 23 is located on the slide rail 1. The side suction collection hood 2 moves on the slide rail 1 through the pulley 23. Since the side suction collection hood 2 is large in size and heavy in weight, using the pulley 23 to move it saves time and effort.

[0034] In one embodiment, a locking and fixing device 24 is provided between the side suction collection hood 2 and the slide rail 1. The locking and fixing device 24 can be a buckle, a latch or other fixed locking structure in the prior art, which is used to fix the side suction collection hood 2 at a certain position on the slide rail 1; the cone crusher 100 will generate strong vibration during operation, and the side suction collection hood 2 can be effectively prevented from shifting under the action of vibration after being locked and fixed.

[0035] In one embodiment, a limit baffle 11 is provided at the bottom end of the slide rail 1. When the operator forgets to lock the side suction collection hood 2, or the locking device fails, the side suction collection hood 2 slides downward along the slide rail 1 under the action of gravity, and the limit baffle 11 can block the side suction collection hood 2.

[0036] In one embodiment, the sealing curtain 3 is composed of a plurality of curtain pieces, and the curtain pieces are in an independent lifted or drooped state, which will not affect the entry of construction waste from the feed port 202, and at the same time can achieve a better sealing effect.

[0037] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any changes and modifications made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
