Description

Technical Field

[0001] The utility model relates to the field of dust control in production workshops and occupational health engineering regulation and control, and in particular to dust removal equipment for cone crushers. Background Art

[0002] Cone crushers, which perform the primary ore crushing task in the mineral processing process, are key equipment for processing incoming materials in large and medium-sized mines. They are widely used in crushing operations. During operation, the incoming ore at the crusher's feed port carries a significant amount of dust into the crusher. Due to the significant height difference between the crusher's upper feed port and lower discharge port, the material falls to a considerable height. Furthermore, the rotation of the internal moving components creates induced airflow, which, in turn, causes the airflow to circulate through the crusher's various outlets, carrying significant amounts of dust. This causes significant dust dispersion and escape into the crushing area. Excessive dust concentrations in the workplace pose an occupational health hazard to workers, impacting their health and safety. Furthermore, dust deposits on the motor surface and enters the coils, increasing motor heat generation, shortening the equipment's lifespan and increasing operating and maintenance costs. Therefore, it is necessary to develop an efficient dust extraction and purification system for cone crusher discharge to ensure that dust concentrations within the crushing area meet national standards, prevent occupational hazards, protect the health and safety of workers, and improve equipment efficiency.

[0003] In the prior art, the dust removal and purification method for cone crushers is usually to set up dust extraction devices at the feed and discharge ports of the equipment, and uniformly purify the sucked dust to achieve the purpose of dust removal; however, due to the accumulation of crushed materials at the crushing cone inside the cone crusher during operation, the resistance to dust suction increases, affecting the suction and purification effect; at the same time, the large height difference between the feed and discharge ports, coupled with the continuous and uninterrupted swinging motion of the crushing cone, will also cause turbulence in the airflow inside the equipment, making it difficult for the airflow at the upper and lower collection points of the crushed materials to coordinate, and may even lead to the formation of local positive pressure in the crusher, causing dust to escape and unsatisfactory dust control effect.

[0004] Existing suction devices also have a common problem, that is, during the feeding process, the crushed material itself carries a large amount of dust. When it falls from a height and the speed continues to increase, a pressure difference will be formed between the upper and lower surfaces of the material, driving the airflow on the surface of the material to follow the movement of the material. Part of the air is surrounded by the particulate material, forming a mixed flow of material and air; the other part of the airflow is outside the core area of ​​the material, and is subjected to the drag force of the particles to form an orderly flow. The particle flow formed by the particles entraining the airflow gradually expands. When encountering obstacles or collisions, it will suddenly change the direction of movement and release the entrained dust-laden air at the same time, causing the dust in the nearby space to diffuse and escape.

[0005] In view of the shortcomings of the existing technology, there is an urgent need for a control mechanism and device that can perform limited sealing at the feed port and achieve upper and lower coordination of the feed and drop dust collection points, so as to break through the dust suppression and collection problems of the cone crusher from the source, effectively control the spread of dust, and improve the working environment. Summary of the Invention

[0006] The purpose of the utility model is to provide a dust removal device for a cone crusher, which can perform limited sealing on the feed port of the crusher, effectively suppress the diffusion of dust, and at the same time efficiently and collaboratively capture the dust generated by the feed and discharge ports from the upper and lower parts, and dynamically seal the airflow for the dust leakage phenomenon in the gap between the bottom of the crusher and the ground under high-frequency vibration, thereby improving the dust control efficiency and extending the service life of the crusher. The device includes a swirl air curtain soft sealing system, a dust collection and treatment system for the crushed material feed port, a dust collection and treatment system for the crushed material discharge port, and a bottom dynamic airflow sealing device.

[0007] The swirl air curtain soft sealing system is located at the upper feed port of the cone crusher, and includes multiple air curtain generators. The air curtain generators are connected to the air supply fan. The air curtain generators are provided with an air supply trough structure. A top dust cover is provided above the air curtain generator, and side dust covers are provided around the air curtain generators. The air curtain generators are arranged around the dust-generating area of ​​the feed port, and the generated air curtains are connected end to end to form an "invisible transparent barrier" to isolate the dust-generating area from the outside air.

[0008] The feed inlet dust collection and processing system includes a feed inlet suction port, a feed inlet dust collection pipe, and a feed inlet dust collector, wherein the feed inlet suction port is arranged at the center position above the dust generating area, that is, the upper center of the swirl air curtain soft sealing system, and is connected to it, and the dust-containing air within the soft sealing range is sucked into the feed inlet dust collector through the feed inlet dust collection pipe for purification, and the dust-containing air is continuously diluted.

[0009] The drop port dust collection and treatment system is arranged at the drop port position at the bottom of the cone crusher, and includes a drop port sealing groove, multi-layer soft sealing materials, a drop port suction port, a drop port dust collection pipe, and a drop port dust collector to achieve the sealing of the drop port dust-generating area and the dust suction and purification. The drop port sealing groove is made of steel material and has a long strip structure. It is connected to the side structure of the drop port belt to seal the entire drop port area (including the drop port and the drop port belt) to achieve the sealing of the drop port area; a drop port suction port is set on the drop port sealing groove. The dust-laden air at the material drop is sucked and enters the material drop dust collector through the material drop dust collecting pipe. A multi-layer soft sealing material structure is set at the outlet of the sealing groove of the material drop to increase the limited sealing resistance, thereby increasing the suction resistance of the dust equipment at the material drop to the outside air, so as to achieve the component balance of the suction airflow inside and outside the equipment. The multi-layer soft sealing material structure is in the shape of a curtain and is installed on the outlet end face of the sealing groove, including a damping curtain, a mounting base plate, a mounting pressure arm, a quick-release handle, etc., which can be quickly installed, disassembled and replaced, and is convenient for daily maintenance.

[0010] The bottom dynamic airflow sealing device is installed between the chassis of the cone crusher and the ground. It has a disc-shaped structure and includes an air inlet, a base, a panel, an air suction port and a sealing rubber strip. The base and the panel are combined to form a circular structural frame of the sealing device. The interior of the frame is hollow and serves as a closed channel for dynamic airflow. An air suction port is set on one side of the channel to connect to a dust collector. During operation, the dust collector sucks through the air suction port to collect and process the dust leaked during the high-frequency vibration grinding of the cone crusher through the dynamic airflow closed channel. A sealing rubber strip is set on the contact surface between the top panel of the sealing device and the chassis of the cone crusher to increase the sealing performance of the panel and the chassis of the cone crusher.

[0011] Preferably, it also includes an air distribution box, an air distribution duct, and an air distribution duct interface. The air distribution box is connected to the air supply fan, and the air distribution duct is connected to the air distribution box through the air distribution duct interface to achieve stable air supply to the air curtain generator.

[0012] In order to achieve control, the dust removal equipment of the cone crusher includes a dust collection and processing control system at the feed port and a dust collection and processing control system at the discharge port. The air exhaust volume of the feed suction port is controlled by the dust collection and processing control system at the feed port, and the air exhaust volume of the discharge suction port is controlled by the dust collection and processing control system at the discharge port.

[0013] The swirl wind curtain soft sealing system is an important component of the present invention. The high-pressure fan is adjusted by the frequency converter to provide an appropriate amount of air to enter the wind curtain generator. The wind curtain generator has an air supply trough structure inside. The air supply trough structure of the wind curtain generator is provided with a wind curtain generator guide blade structure. The air volume is blown out after passing through the air supply trough and guide blades of the wind curtain generator to form a plane jet wind curtain. The present invention can adopt 4 cylindrical wind curtain generators, which are arranged in a square. The generated wind curtains are connected end to end to achieve soft sealing of the dust-producing area. Compared with the traditional method of extracting dust without sealing at the feed inlet, it solves the problem of outward diffusion of dust in the sealed space and effectively suppresses the diffusion of dust at the feed inlet.

[0014] The dust collection and treatment system for the crushed material inlet is another important component of the utility model. The inlet suction port of the dust collection and treatment system for the crushed material inlet is arranged at the center position above the swirl air curtain soft sealing system, guiding the dust-laden air within the soft sealing range of the air curtain into the dust collection pipe of the inlet under the negative pressure of the suction airflow, and finally reaching the dust collector of the inlet for purification.

[0015] The dust collection and treatment system for the crushed material drop-out port is located around the drop-out port of the cone crusher, and is provided with a drop-out port sealing groove, which is installed and connected to the suction equipment to suck the dust from the drop-out port and enter the drop-out port dust collector through the drop-out port dust collection pipe to complete the air suction and purification at the drop-out port; in addition, multiple layers of soft sealing materials are designed and installed at the outlet position of the guide trough to increase the suction resistance of the drop-out port dust collection equipment to the external air, so as to achieve a weight balance of the suction airflow inside and outside the equipment, and achieve better dust suction and purification effect.

[0016] Preferably, the bottom dynamic airflow sealing device is installed in the gap between the bottom surface of the cone crusher and the ground. A dynamic airflow channel is provided inside the sealing device. An air suction port is provided at one end of the channel and is connected to the dust collector. An air inlet is provided at the other end. During operation, the dust collector is turned on, and the dust leaked from the high-frequency grinding of the vibrating part of the cone crusher enters the bottom dynamic airflow sealing device under the action of suction, passes through the dynamic airflow channel therein, and enters the dust collector for purification, thereby realizing the control of the dust leakage from the high-frequency grinding of the vibrating part.

[0017] The method for determining the closed channel area and dynamic sealing air volume is as follows:

[0018]

[0019] Among them, Q represents the dynamic sealing air volume, is the flow coefficient of the dynamic sealing section, A is the dynamic sealing cross-sectional area, is the gas density, is the static pressure of the dynamic sealing channel;

[0020] The flow coefficient of the dynamic sealing section is the ratio of the flow rate of gas passing through the dynamic sealing section when the dynamic sealing device is in operation to the theoretical flow rate, and is calculated by measuring the actual flow rate and the theoretical flow rate.

[0021] The application of the upper and lower dust-catching airflow control strategy of the feed port and the drop port is another major feature of the utility model. By studying the coupling law of the suction airflow of the upper feed port and the lower drop port, and according to the material accumulation situation inside the cone crusher, the upper and lower dust-catching suction airflows are adjusted to a specific proportion, so that the suction airflows of the feed and the drop port dust collection can achieve pressure balance, so that the interior of the crusher is in a negative pressure state, forming a coordinated operation of the upper and lower dust-catching suction airflows. Compared with the single suction purification method of the upper feed port and the lower drop port, it can effectively reduce the probability of dust escape and improve the dust purification efficiency.

[0022] The discharge of the cone crusher will generate a large amount of impact airflow. The impact airflow is related to the material flow rate, material density, material particle size, drop height, etc. In the typical link of the cone crusher, the impact airflow can be calculated according to the following formula:

[0023]

[0024] in Q Indicates the impact gas flow rate; μ is the air flow viscosity; D is the barrel diameter of the cone crusher; ρ g and ρ p are gas and material densities respectively; m p is the material mass flow rate; d p is the material particle size, h is the material falling height; g is the acceleration of gravity; A and b are empirical constants related to the position and structural parameters of the cone crusher rolling rod, among which the cone crusher rolling rod position coefficient can be determined according to the ratio of the distance L between the highest position of the cone crusher and the material falling to the lower belt. When the cone crusher rolling rod is located in the upper 1 / 3 area of ​​L, the value of A is 2; when the cone crusher rolling rod is located in the middle 1 / 3 area of ​​L, the value of A is 1.5; when the cone crusher rolling rod is located in the lower 1 / 3 area of ​​L, the value of A is 1; the cone crusher rolling rod structural parameters are determined by the ratio of the rolling rod diameter to the transparent area at the rolling rod. When the ratio is 5-8, b is 1.5; when the ratio is 3-4, b is 1.2; when the ratio is 1-2, b is 1. If the ratio is not an integer, it can be rounded up. The air volume Q of the upper feeding suction port 25 上 , the air volume Q of the lower feeding suction port 26 下 , and its relationship with the falling material impact airflow is as follows:

[0025] (1) First, Q 下 Calculated from the range of Q value:

[0026] Q 下 = (1.3~1.8) Q

[0027] Among them, the value of 1.3~1.8 is determined by the hollow cross-sectional area S at the outlet of the guide trough. When the hollow cross-sectional area S=the cross-sectional area of ​​the guide trough, take 1.3; when S=0.5×the cross-sectional area of ​​the guide trough, take 1.8, and the intermediate interpolation calculation is performed.

[0028] (2) Secondly, Q 上 Calculated from the range of Q value:

[0029] Q 上 = (0.3~0.6) Q

[0030] The value of 0.3~0.6 is determined by the ratio of the maximum crushing section to the minimum crushing section of the crushing cone inside the cone crusher. When the ratio is 3~1.5, take 0.3; when the ratio is 1.5~1, take 0.6, and interpolation is used in between.

[0031] In summary, the dust extraction and purification method and device for cone crusher falling materials of the present invention have the advantages of high efficiency, environmental protection and low consumption. It can effectively suppress dust diffusion and realize efficient dust extraction and purification. It is suitable for cone crushing operations where dust diffusion is more serious.

DETAILED DESCRIPTION

[0043] The following is a detailed description of the technical solution of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention, but the present invention is not limited to the following embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] A method and device for extracting and purifying dust generated by falling materials of a cone crusher, such as Figure 1 As shown, the device includes a swirl air curtain soft sealing system 1, a crushed material inlet dust collection and treatment system 2, a crushed material outlet dust collection and treatment system 3 and a bottom dynamic airflow sealing device 4.

[0045] like Figure 2-3As shown, the swirl air curtain soft sealing system 1 is located at the upper feed port of the cone crusher 16, that is, at the crushed material feed end belt 21 shown in Figure 3, and is composed of four cylindrical air curtain generators 6 arranged in a square. The air curtain generator 6 is cylindrical in shape and has an air supply trough structure 23 on it. Each air curtain generator generates a plane jet air curtain at a certain angle and in the same rotation direction, isolating the dust-generating area of ​​the feed port from the outside air through an "invisible transparent barrier" connected end to end; a top shield is set above the air curtain. The dust cover 7 is surrounded by side dust covers 20 for sealing connection with the dust collection and processing system 2 at the crushing material inlet; the air curtain generator 6 is composed of an air supply fan 5, which is divided into four air distribution ducts 18 on the left and right sides through an air distribution box 17. Each air distribution duct 18 is connected to the air distribution box 17 through an air distribution duct interface 19, and the air is respectively sent into the four air curtain generators 6, realizing the function of converting the air outlet of the fan into the air supply outlet of the four air curtain generators, ensuring the stable air supply of the air curtain generator; such as Figure 4 As shown, the structure of the wind curtain generator 6 includes: a wind curtain generator main structure 22, an air supply trough structure 23 of the wind curtain generator and a wind curtain generator guide blade structure 24, wherein the angle and spacing of the guide blades are matched with the actual situation on site, so that the deflection of the wind curtain meets the on-site requirements, forming a uniform and stable soft-sealed cross-flow wind curtain, and an air distribution box sealing gasket is installed at the installation connection between the air supply fan 5 and the air distribution box 17, and a sealing connection mechanism is installed at the installation connection between the air distribution duct 18 and the wind curtain generator 6 to ensure the sealing and continuous stability of the air supply.

[0046] like Figure 5 As shown, the dust collection and treatment system 2 for the crushed material feeding port has an inlet suction port 25 connected to the wind curtain generator 6 through a top dust cover 7, so as to realize dust suction at the center above the dust-producing area of ​​the feeding port. Under the negative pressure of the suction airflow, the dust-laden air within the soft sealing range is continuously diluted and taken away, so that the dust does not pass through the wind curtain, but directly passes through the dust collecting pipe 8 above the feeding port to the feeding port dust collector 9 for purification.

[0047] like Figure 6-7 As shown, the dust collection and treatment system 3 for the crushed material discharge port is located near the discharge port of the cone crusher on the negative first floor, wherein the discharge port sealing groove 11 is installed and fixed above the discharge belt and is connected to the side structure of the discharge belt, so that the discharge area sealed above the discharge belt is sealed as a whole, and a discharge suction port 26 is provided on the discharge port sealing groove 11 to suck the dust-containing air at the discharge location and enter the discharge port dust collector 14 through the discharge port dust collecting pipe 13. At the same time, multiple layers of soft sealing material 12 are added at the outlet position of the discharge port sealing groove 11 to increase the suction resistance of the lower discharge port dust collection equipment to the outside air, ensure the weight balance of the suction airflow inside and outside the equipment, and achieve better dust suction and purification effect.

[0048] like Figure 9-10 As shown, the dynamic airflow sealing device 4 at the bottom of the cone crusher is located in the gap between the cone crusher chassis 28 and the ground. Its top surface is in contact with the cone crusher chassis, and the sealing performance with the crusher chassis is increased by a sealing rubber strip 32. The bottom surface of the sealing device is placed on the ground and is sealed internally. The main structure of the dynamic airflow sealing device 4 at the bottom of the cone crusher is composed of an air inlet 27, a base 29, a panel 30, and an air suction port 31, forming a circular ring structure with a hollow interior and a dynamic airflow channel. At one end of the sealing device, a suction port 31 is provided to connect to the dust collector and extend out of the gap between the crusher and the ground. When the system is running, the bottom dynamic airflow sealing device allows the dust-laden air at the bottom of the cone crusher to enter the dust collector along the dynamic airflow channel through the air suction port under the suction of the dust collector, thereby achieving the suction and purification of the large amount of dust leaked from the bottom of the cone crusher when the cone crusher vibrates at high frequency.

[0049] In addition, the present invention has a mechanism for adjusting the ratio of the upper and lower dust-collecting suction airflows, that is, considering the accumulation of materials in the crushing chamber of the cone crusher, the coupling law of the suction airflows of the upper feed port and the lower drop port under different material amounts is studied respectively. When there is no material accumulation in the crushing chamber, the suction resistance is small, and the upper and lower dust-collecting suction airflows are used to suck and capture dust according to a specific ratio, interfering with the movement of dust in the cone crusher with the airflow; when there is a large amount of material accumulation in the crushing chamber, the suction resistance becomes larger, and the ratio of the upper and lower dust-collecting suction airflows is changed and adjusted, which can effectively avoid the formation of local positive pressure in the cone crusher and aggravate the dust escape phenomenon. In addition, when the crusher is not crushing materials, the device can also be turned on to blow and suck the residual dust inside the crusher to realize the dust cleaning function inside the crusher.

[0050] This utility model mining belt cleaning device can be used in various situations such as underground coal mines and coal mine surface conveying systems. Through reasonable design and configuration, each component can operate stably and long-term in harsh environments, improving the cleaning effect and service life of the conveying system, and reducing workers' labor intensity and dust pollution.

[0051] The embodiments of this utility model provide a detailed description of a method and apparatus for extracting and purifying dust generated by a cone crusher. However, the scope of protection of this utility model is not limited thereto. Any modifications, replacements, improvements, and equivalents within the spirit and principles of this utility model are intended to be included within the scope of protection of this utility model. For example, the number and arrangement of air curtains and dust removal systems can be adjusted based on the actual conditions of the crushing operation site, and the number and structure of the internal guide vanes of the air curtains can also be optimized based on specific circumstances to achieve optimal results.
