Description

Technical Field

[0001] The present invention belongs to the technical field of mineral delivery equipment, and specifically relates to a suspended vibrating feeder. Background Art

[0002] A vibrating feeder is a device widely used in fields such as mining, ore dressing, and ore crushing. It uses the vibration principle to evenly feed ores from the ore pile into subsequent processes such as crushing, grinding, and ore dressing.

[0003] Since the vibrating feeder generates regular vibrations of the hopper through a vibrating motor during operation, causing the minerals to move forward, when the dust content of the conveyed minerals is relatively high, a large amount of dust is easily generated during the up-and-down vibration of the minerals, thereby polluting the environment and the surrounding workers. To prevent dust pollution during the vibrating feeding process, dust reduction equipment is usually installed in the feeding trough and discharging trough of the vibrating feeder. By settling or collecting the dust, the effect of reducing dust pollution is achieved.

[0004] For example, the Chinese patent with the authorization announcement number CN219990601U discloses a vibrating feeder with a dust reduction structure for sulfur concentrate. In this solution, the dust suction trough of the vibrating feeder forms a vertical lifting structure with a water storage tank through a telescopic arm under the action of an electric push rod, and the dust suction trough forms a suction structure with a dust collection box through a dust suction pipe and an L-shaped air extraction pipe under the action of a fan, so as to lift the dust suction trough according to the height of the sulfur ore, so that the dust suction trough can be close to the surface of the sulfur ore for dust suction, thereby avoiding increasing the diffusion range of dust. The spray head of the device forms a communication structure with a water source through a spray arm and a water inlet pipe, and the water storage tank forms a supporting structure with the sewage formed by the spray head and the dust, so as to collect the sewage generated after dust reduction through the water storage tank. However, it is found in the actual application process that since the dust emission rate and dust emission position of the vibrating feeder are not constant during actual operation, the dust reduction mechanism with a constant power cannot be adjusted in real time according to the dust emission situation during actual use. Therefore, when the power of the dust reduction mechanism is large, there is a serious energy consumption problem, and when the power of the dust reduction mechanism is low, there is a problem of poor dust reduction effect.

[0042] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0043] As Figures 1 to 9 shown, a suspension vibrating feeder according to the present invention includes a feeder main body 1, and a cantilever 11 is installed on the feeder main body 1. The cantilever 11 is used to connect with a suspension device so as to suspend and install the feeder;

[0044] It further includes a dust suppression mechanism, which is installed on the feeder main body 1 and is used to suppress the dust emitted by the feeder main body 1 to the outside;

[0045] The dust suppression mechanism includes a baffle 2, an atomizing head 23, a negative pressure head 24 and a circulation pump 25;

[0046] The baffle 2 is fixedly installed on the feeder main body 1. The baffle 2 and the feeder main body 1 cooperate to form a feeding trough 21 and a discharging trough 22. The baffle 2 is detachably installed above the feeder main body 1 to block the opening of the feeder main body 1. Since the length of the baffle 2 is less than the length of the feeder main body 1, the baffle 2 and the feeder main body 1 cooperate to form the feeding trough 21 and the discharging trough 22 at both ends of the feeder main body 1, which are respectively used to receive the ore falling from the hopper and make the ore be evenly transported under the vibration action;

[0047] Uniformly distributed atomizing heads 23 are installed at the feeding trough 21 and the discharging trough 22. The atomizing heads 23 are all externally connected to a water supply pipeline. Due to the structure of the atomizing heads 23 themselves, the water flow is quickly sheared and dispersed under the action of high-pressure gas and is sprayed out in the form of water mist. The action mechanism of the atomizing heads 23 is common knowledge in conventional technologies and will not be described in detail here;

[0048] A negative pressure head 24 is installed in the feeder main body 1. The negative pressure head 24 is connected to the input end of the circulation pump 25 through a pipeline, and the output end of the circulation pump 25 is connected to the atomizing head 23 to provide compressed gas for the atomizing head 23.

[0049] When using a vibrating feeder to transport ore, due to the vibration and the impact generated by the movement of the ore, the finer powder in the ore will be carried by the air flow and then diffuse into the air. And the top opening area of a conventional vibrating feeder is relatively large, so that the dust diffusion channel is relatively wide, which is not convenient for suppressing dust. In order to facilitate dust suppression in the present invention, a dust suppression mechanism is provided on the feeder main body 1, and the convenience of dust suppression operation is enhanced by fixing the position of the channel opening and reducing the opening area.

[0050] Specifically, in the present invention, the baffle plate 2 seals the top opening of the ore feeder main body 1, resulting in a significant reduction in the conduction area between the ore feeder main body 1 and the outside world. At the same time, the conduction position is fixed, effectively increasing the difficulty of dust escaping into the air and fixing the escape position. Meanwhile, the atomizing heads 23 installed at the ore feeding trough 21 and the ore discharging trough 22, with the support of the water supply pipeline and the circulating pump 25, break the water using compressed air and spray it in the form of water mist at the ore feeding trough 21 and the ore discharging trough 22. The water mist captures the dust dispersed in the air and finally settles under the action of gravity. At the same time, the negative pressure head 24 installed inside the ore feeder main body 1 continuously extracts the air inside the ore feeder main body 1 under the negative pressure of the circulating pump 25 until the outside air flows into the ore feeder main body 1 through the ore feeding trough 21, the ore discharging trough 22 or the gaps of the ore feeder main body 1, thereby effectively reducing the degree of dust diffusion to the outside. It should be noted that in order to prevent dust from damaging the circulating pump 25, an air flow filtering device is installed between the negative pressure head 24 and the circulating pump 25 in the present invention to filter the dust in the extracted air. Finally, the circulating pump 25 pumps the extracted air into the atomizing head 23 for forming water mist.

[0051] By setting the dust suppression mechanism in the present invention, the opening of the ore feeder main body 1 is blocked, resulting in a significant reduction in the conduction area between the ore feeder main body 1 and the outside world. At the same time, the conduction position is fixed to facilitate the centralized water mist sprayed by the atomizing head 23 and enhance the suppression effect on the escaping dust. At the same time, negative pressure suction is combined with atomizing dust reduction, causing the air, water mist, and dust to form a directional flow, further reducing the degree of dust dispersion in the air.

[0052] It further includes an efficacy adjustment mechanism. The efficacy adjustment mechanism is installed on the ore feeder and is used to adjust the efficacy of the dust suppression mechanism;

[0053] The efficacy adjustment mechanism includes a baffle plate 26 and a control valve 3;

[0054] Baffle plates 26 are rotatably installed in both the ore feeding trough 21 and the ore discharging trough 22. The baffle plates 26 are installed obliquely and are located on the movement path of the minerals. The presence of the baffle plates 26 can not only buffer the impact force of the ore falling but also further block the ore feeding trough 21 and the ore discharging trough 22 to reduce the probability of dust escaping;

[0055] Support rods 27 are hingedly installed in both the ore feeding tank 21 and the ore discharging tank 22. The support rods 27 are all spring telescopic rods. The support rods 27 are all hingedly connected to the baffle 26. The support rod 27 is composed of a fixed end, a sliding rod and a spring. When the length of the support rod 27 decreases or increases, the volume of the rodless cavity of the fixed end decreases or increases, thereby pressurizing or depressurizing the hydraulic oil inside the support rod 27. Utilizing the flow of the hydraulic oil, the transmission between the support rod 27 and the hydraulic pipe 4 is realized;

[0056] The control valve 3 is installed on the flow blocking plate 2. An opening knob 31 is installed on the control valve 3. The opening knob 31 is in transmission connection with the support rod 27 through a transmission member. The control valve 3 is located between the atomizing head 23 and the water supply pipeline. The control valve 3 is used to control the water supply speed.

[0057] The control valve 3 is a ball valve control valve 3. The rotation angle of the opening knob 31 is positively correlated with the opening size of the water flow channel inside the control valve 3. In the present invention, the ball valve spool inside the control valve 3 and the opening knob 31 are integrally arranged. When the opening knob 31 rotates, the hole grooves on the spool are aligned or misaligned with the hole grooves of the control valve 3, thereby increasing or decreasing the cross-sectional area of the water flow channel inside the control valve 3 to achieve the effect of controlling the water flow rate.

[0058] The transmission member includes a hydraulic pipe 4, a transmission rack 42 and a transmission wheel 43;

[0059] The hydraulic pipe 4 is fixedly installed on the flow blocking plate 2. A rod-shaped piston 41 is hermetically and slidably installed inside the hydraulic pipe 4. The hydraulic pipe 4 is connected to the support rod 27 through a pipeline. The hydraulic pipe 4 and the support rod 27 are filled with hydraulic oil;

[0060] The rod-shaped piston 41 is fixedly installed with a transmission rack 42. The transmission rack 42 extends outside the hydraulic pipe 4. The opening knob 31 is fixedly installed with a transmission wheel 43. The transmission rack 42 is in meshing transmission with the transmission wheel 43.

[0061] In order to improve the water-saving effect of the equipment while ensuring the dust suppression effect and making the equipment conform to the environmental protection concept of green environmental protection, a power adjustment mechanism is also provided in the present invention. When the ore feeder is in normal use, since the speed of unloading ore in the hopper is not uniform, and sometimes even leads to the interruption of ore feeding, there is also a probability of interruption during the operation of the ore feeder. In order to reduce the energy consumption during interruption, when the ore falls from the hopper into the feeding chute 21 or the ore in the main body 1 of the ore feeder is output from the ore unloading chute 22, under the action of gravity and thrust, the ore impacts the baffle 26 in the feeding chute 21, causing the baffle 26 in the feeding chute 21 to deflect. Since the baffle 26 is supported by the support rod 27, when the baffle 26 deflects, the length of the support rod 27 composed of the spring telescopic rod changes accordingly. Then, under the transmission action of the hydraulic oil filled in the support rod 27 and the hydraulic pipe 4 together, the rod-shaped piston 41 moves in the hydraulic pipe 4, and the transmission rack 42 fixedly installed on the rod-shaped piston 41 moves synchronously. Under the meshing transmission action, the linear movement of the transmission rack 42 will cause the transmission wheel 43 to rotate, forcing the water flow channel in the control valve 3 to change, and finally realizing the adjustment of the spraying efficiency of the atomizing head 23. Specifically, when the ore feeding amount of the hopper is large, the feeding speed is fast, and the ore unloading amount of the main body 1 of the ore feeder is large, at this time, the amount of dust generated is large. Under the impact of the ore, the deflection angle of the baffle 26 will increase. Under the transmission effect of the transmission parts, the cross-sectional area of the water flow channel in the control valve 3 increases, and the spraying efficiency of the atomizing head 23 increases, thereby increasing the suppression and settlement of dust. When the ore feeding amount of the hopper is small, the feeding speed is slow, and the ore unloading amount of the main body 1 of the ore feeder is small, at this time, the amount of dust generated is small. At this time, the impact of the ore on the baffle 26 decreases, and then the baffle 26 is reset under the action of the support rod 27. As the reset degree of the baffle 26 increases, the opening degree of the control valve 3 gradually decreases, and then the spraying efficiency of the atomizing head 23 decreases to achieve the purpose of saving water flow.

[0062] By setting the baffle 26, the support rod 27 and the control valve 3, in the actual transportation of ore, the change in the ore supply rate is used as the condition for the change in the water supply rate of the atomizing head 23, so that the spraying efficiency of the water mist is positively correlated with the ore supply efficiency. Thus, while maintaining the dust suppression effect, the input of water flow is effectively saved, which can not only reduce the waste of water resources, but also reduce the probability of problems such as the surface of the ore feeder being wet and muddy caused by excessive spraying of water mist.

[0063] As a preferred embodiment of the present invention, the power adjustment mechanism further includes a scissor-type telescopic frame 5;

[0064] On one side of the baffle 2 close to the ore feeder main body 1, a scissor-type telescopic frame 5 is installed. The scissor-type telescopic frame 5 is located at both ends of the baffle 2. The negative pressure heads 24 are designed in plural and are evenly distributed on the scissor-type telescopic frame 5. A plurality of negative pressure heads 24 are connected through pipes and are finally conducted to the input end of the circulating pump 25. When the circulating pump 25 operates, negative pressure is transmitted to the negative pressure heads 24. In the initial state, both groups of the scissor-type telescopic frames 5 are in the extended state, and the negative pressure heads 24 are evenly distributed on the baffle 2. By default, it is considered that there is no ore in the initial state.

[0065] One end of the scissor-type telescopic frame 5 is fixedly installed on the baffle 2. A connecting plate 56 is installed on the scissor-type telescopic frame 5, and the connecting plate 56 is fixedly connected with the transmission rack 42.

[0066] When the ore feeding amount is large, the dust accounts for a large proportion at the ore feeding port and the ore discharging port. When the ore feeding amount is small, the vibration effect of the ore inside the ore feeder main body 1 is good, so that the dust dispersion degree inside the ore feeder main body 1 is large. In order to flexibly collect the dispersed dust, when the baffle 26 deflects in the present invention, at this time, under the action of the support rod 27 and the transmission member, the transmission rack 42 drives the connecting plate 56 to move, and the connecting plate 56 pulls the node of the scissor-type telescopic frame 5 to move. Since the scissor-type telescopic frame 5 is composed of a plurality of crossed X-shaped mechanisms hinged together, and the position of one end of it is relatively fixed with respect to the baffle 2, when one of the nodes of the scissor-type telescopic frame 5 is pushed, it will cause the angle of the X-shaped structure of the scissor-type telescopic frame 5 to change, thereby making the scissor-type telescopic frame 5 extend or shorten. Therefore, when the ore feeding amount is large and the deflection angle of the baffle 26 is large, the transmission rack 42 and the connecting plate 56 push the distance between two adjacent nodes of the scissor-type telescopic frame 5 to decrease, thereby making the length of the scissor-type telescopic frame 5 shrink, so that the positions of the negative pressure heads 24 installed on the scissor-type telescopic frame 5 are concentrated towards the ore feeding trough 21 and the ore discharging trough 22, so as to suppress the dust generated at the ore feeding trough 21 and the ore discharging trough 22. When the ore feeding amount is small, at this time, the deflection angle of the baffle 26 decreases, the length of the scissor-type telescopic frame 5 increases, and thus the negative pressure heads 24 are dispersed inside the ore feeder main body 1, and the dust is collected in time during the generation of the dust.

[0067] By setting structures such as the scissor-type telescopic frame 5 in the present invention, taking the ore feeding amount as the adjustment condition, the device can automatically adjust the distribution position of the negative pressure heads 24 according to the size of the ore feeding amount, so as to flexibly collect the generated dust. It not only effectively improves the dust suppression effect, but also the self-adjustment effect of the device makes the device more convenient to use.

[0068] As a preferred embodiment of the present invention, a guiding strip 51 is fixedly installed on the baffle 2. The guiding strips 51 are all C-shaped structures. The scissor-type telescopic frame 5 is slidably installed on the guiding strip 51, and the guiding strip 51 is used to provide support for the scissor-type telescopic frame 5.

[0069] The surfaces of the guiding strips 51 are all smooth. A dust collection cover 53 and a filter screen 54 are sleeved on the negative pressure heads 24. The dust collection cover 53 is open on the side away from the negative pressure head 24. A conical plug 55 is detachably and fixedly installed at the opening of the dust collection cover 53. When the circulation pump 25 is started, negative pressure acts on the conical plug 55 through the negative pressure head 24, thereby causing the conical plug 55 to open, and the dust-containing air flows into the negative pressure head 24. Among them, the dust is directly filtered by the filter screen 54, and most of the large-particle dust is intercepted first.

[0070] Arc-shaped bumps 52 are fixedly installed on the guiding strips 51, and the arc-shaped bumps 52 are located on the telescopic path of the scissor-type telescopic frame 5. When the ore continuously moves into the main body 1 of the feeder, the non-constant feeding rate of the ore will cause the baffle 26 to swing reciprocally, thereby causing the scissor-type telescopic frame 5 to contract and extend frequently and slightly. During this process, the scissor-type telescopic frame 5 is guided by the arc-shaped bumps 52 and cooperates with the vibration of the main body 1 of the feeder to form a larger vibration. Due to the effect of the vibration, therefore, during long-term operation, every once in a while, the circulation pump 25 is turned off. Under the action of the vibration, at this time, the conical plug 55 is closed, and the filter screen 54 will drop the intercepted dust into the dust collection cover under the action of the vibration and gravity. It should be noted that in order to further improve the effect of the vibration on the filter screen 54, a plurality of impact balls are filled above the filter screen 54, and the filter screen 54 is made of an elastic material, thereby enhancing the effect of removing dust by vibration.

[0071] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
