Description

Technical Field

[0001] This utility model belongs to the technical field of transportation diversion equipment, specifically relating to a high-efficiency negative pressure dust removal vibration material distribution device. Background Technology

[0002] Distributors are widely used in industries such as mining and metallurgy as transport and diversion equipment. They can control the transport direction of powder in different pipelines and dynamically adjust the transport path of powder.

[0003] Existing distributors have significant drawbacks when transporting powdery materials: during the falling process, the powder will collide with the distribution plate, inner wall, transport vehicle or belt, generating a large amount of dust; after the distributor switches the distribution plate and changes the transport direction, due to reasons such as poor sealing of the distribution plate and residual powder falling off the inner wall, some powder will fall to the ground when there is no vehicle below the discharge port, causing serious pollution to the working environment, vehicle exterior and transport route, and posing a threat to the health of the workers. Utility Model Content

[0004] This invention addresses the aforementioned problems and overcomes the shortcomings of existing technologies by providing a high-efficiency negative pressure dust removal vibration dispensing device. This invention can reduce the environmental pollution caused by residual particles and powder in the dispensing device and can suppress the generation and diffusion of dust.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] This utility model provides a high-efficiency negative pressure dust removal vibrating material distribution device, including a material distributor, a material distribution plate hinged inside the material distributor, and a push rod device connected to the outside of the material distributor. The material distribution plate and the push rod device form a crank-connecting rod structure, and the push rod device drives the material distribution plate to swing. The top of the material distributor is provided with a material inlet, and the bottom of the material distributor is provided with two material outlets. The device is characterized in that a vibration device is provided on the outer wall of the material distributor, which can drive the material distributor to vibrate. A negative pressure port is also provided on the side wall of the material distributor, and a negative pressure device is connected to the negative pressure port to provide a negative pressure environment inside the material distributor. Each material outlet of the material distributor is provided with a dust suppression nozzle assembly.

[0007] Furthermore, the negative pressure device includes a negative pressure hood, a negative pressure pipe, and an axial flow fan. The negative pressure hood is connected to the outer wall of the distributor corresponding to the negative pressure port. The two ends of the negative pressure pipe are respectively connected to the negative pressure hood and the axial flow fan. The axial flow fan is then connected to an external negative pressure dust treatment system.

[0008] Furthermore, the dust suppression nozzle assembly includes two inner large-diameter nozzles and two outer small-diameter nozzles, with the large-diameter nozzles pointing downwards towards the powder and the small-diameter nozzles pointing outwards towards the powder.

[0009] The beneficial effects of this utility model.

[0010] This invention can vibrate away particles and powders that are difficult to discharge from the distributor, preventing them from polluting the working environment. The negative pressure device can collect and treat fine dust remaining in the pipeline and dust generated by the collision of powder with mine cars or conveyor belts, reducing environmental pollution and material waste. The dust suppression device can further suppress the generated dust and settle suspended dust, inhibiting the generation and spread of dust from its source and throughout its diffusion process. Attached Figure Description

[0011] To make the technical problems solved, the technical solutions, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0012] Figure 1 This is a structural schematic diagram of the present invention in its initial state.

[0013] The markings in the diagram are as follows: 1 is the distributor, 2 is the distributor plate, 3 is the push rod device, 4 is the feed inlet, 5 is the vibration device, 6 is the negative pressure hood, 7 is the negative pressure pipeline, 8 is the axial flow fan, 9 is the negative pressure dust treatment system, 10 is the large diameter nozzle, 11 is the small diameter nozzle, 12 is the hopper, and 13 is the discharge port. Detailed Implementation

[0014] As shown in the accompanying drawings, this embodiment provides a high-efficiency negative pressure dust removal vibration distribution device, including a distributor 1, a distribution plate 2 hinged inside the distributor 1, and a push rod device 3 connected to the outside of the distributor 1. The distribution plate 2 and the push rod device 3 form a crank-connecting rod structure. The push rod device 3 drives the distribution plate 2 to swing, and the powder enters the distributor 1 from the hopper 12 and is distributed to different distribution hoppers through the distribution plate 2.

[0015] The top of the distributor 1 is provided with a feed inlet 4, which is used to receive the powder in the hopper 12 into the distributor 1. The bottom of the distributor 1 is provided with two discharge outlets 13, which correspond to different hoppers below.

[0016] A vibration device 5 is provided on the outer wall of the distributor 1. The vibration device 5 can drive the distributor 1 to vibrate. After the distributor 1 switches the discharge direction, the vibration device 5 is activated. The vibration will remove the residual powder on the inner wall of the distributor 1 and the distributor plate 2 in advance, so as to prevent the vibration generated when the distributor 1 is filling the other side of the material from being transmitted to the closed side, which would cause the powder on the closed side to fall uncontrollably and cause pollution.

[0017] A negative pressure port is also provided on the side wall of the distributor 1. A negative pressure device is connected to the negative pressure port. The negative pressure device includes a negative pressure hood 6, a negative pressure pipe 7, an axial flow fan 8, and a negative pressure dust treatment system 9. The negative pressure hood 6 is connected to the outer side wall of the distributor 1 corresponding to the negative pressure port. The two ends of the negative pressure pipe 7 are connected to the negative pressure hood 6 and the axial flow fan 8, respectively. The axial flow fan 8 is then connected to the negative pressure dust treatment system 9.

[0018] When the distributor 1 discharges material, the axial flow fan 8 is started to draw out the air and dust inside the negative pressure pipe 7 and the negative pressure hood 6 to form a negative pressure environment. This can draw the air and dust inside the distributor 1 and near the discharge port 13 into the negative pressure pipe 7 to prevent them from overflowing into the air. The negative pressure device collects the dust inside the distributor 1 and the dust near the discharge port 13 and discharges it to the negative pressure dust treatment system 9 for solid-gas separation, and then recovers the separated powder.

[0019] Each discharge port 13 of the distributor 1 is equipped with a dust suppression nozzle assembly, which is activated synchronously when the distributor 1 discharges material to suppress dust.

[0020] Each dust suppression nozzle assembly includes two inner large-diameter nozzles 10 and two outer small-diameter nozzles 11.

[0021] The large-diameter nozzle 10 points downwards towards the powder. The large-diameter nozzle 10 atomizes water into micron-sized particles. By utilizing the adsorption and agglomeration of droplets and dust particles, agglomerates of dust and water mist are formed. The agglomerates settle down under the influence of gravity.

[0022] The small-diameter nozzle 11 points to the outside of the powder below. The small-diameter water mist generated by the small-diameter nozzle 11 has a small diameter, and the droplets are subject to greater air resistance due to their small diameter. This results in a longer suspension time and better effect, which can form a dense water mist isolation layer on the top of the agglomerates to cover them and allow them to slowly settle, further preventing the agglomerates from overflowing, thereby achieving efficient dust suppression.

[0023] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
