Description

Technical Field

[0001] The invention relates to the technical field of green production, and in particular to a novel dust removal and powder control system. Background Art

[0002] In mining production, a large amount of dust will be generated during the operation of various crushing, screening and conveying equipment, which seriously affects the production environment and also seriously pollutes the surrounding environment. Therefore, the traditional configuration system of "powder selector + bag dust collector" is often used to basically solve the pollution problem.

[0003] In the traditional configuration system of "powder selector + bag filter", the bag filter uses the negative pressure working principle and must overcome the influence of a series of factors such as pipeline pressure loss and bag filter pressure loss, so it consumes a lot of power. If the environment is humid or the moisture content of the material exceeds 1.5%, it will seriously affect the working efficiency of the dust collector.

[0004] In the traditional configuration system of "powder selector + bag dust collector", the powder selector mainly adopts a material distribution mechanism, a fan dust raising mechanism, etc., and is then used in combination with a bag dust collector to achieve the production purpose of powder selection and dust removal, so the power consumption is quite large.

[0005] The traditional configuration system of "powder selection machine + bag dust collector", taking the windproof collection valve (10) 0T / H fine material production line as an example, the power consumption of its dust removal and powder selection system is generally above 375KWH, causing serious energy consumption and also greatly increasing production costs.

[0006] Based on the above reasons, under the premise of ensuring the powder selection and dust removal functions, simplifying the production process and reducing energy consumption have become urgent practical needs. Therefore, it is necessary to propose a new solution to the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide a novel dust removal and powder control system to solve the technical problems raised in the background technology.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new type of dust removal and powder control system, including a crusher body, a crusher rotor, a dust collection device, a powder selector, a vortex cyclone mechanism, a cyclone collection mechanism and a bag dust collector, a crusher rotor is arranged on the inner side of the crusher body, the bottom end of the crusher body is connected to the dust collection device, the top of one side of the dust collection device is connected to the vortex cyclone mechanism and the cyclone collection mechanism in sequence, one side of the dust collection device is connected to the powder selector, and the top of one side of the vortex cyclone mechanism is arranged with a drainage fan. The top of the drainage fan and the top of the cyclone collection mechanism are both connected to a pipeline, the side of the powder selector away from the dust collection device is connected to a three-way valve, and the powder selector is connected to the pipeline and the bag dust collector through the three-way valve.

[0009] Preferably, a grid adjustment mechanism is fixedly connected to the inner side of the vortex cyclone mechanism, and the grid adjustment mechanism separates coarse particles in the dust.

[0010] Preferably, a windproof collection valve is provided at the bottom end of the vortex cyclone mechanism close to the drainage fan, and the windproof collection valve is used to recover coarse particle materials.

[0011] Preferably, the top end of the induced draft fan is connected to the cyclone collection mechanism via a pipeline.

[0013] Preferably, one side of the cyclone is connected to a drainage fan.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention retains the original collecting mechanism and adds a vortex cyclone and a drainage fan to form a vortex cyclone + drainage fan combination. At the same time, a grid adjustment mechanism and a windproof collection valve are added to the vortex cyclone. The following effects are achieved through the combination of the grid adjustment mechanism and the windproof collection valve: by adjusting the grid adjustment mechanism and utilizing the above-mentioned air flow force, coarse particle materials in the dust can be effectively recovered (Note: in crushing production, this coarse particle material is a rare high-quality finished product). The combination of the grid adjustment mechanism and the windproof collection valve can control the dust emission to be reduced by more than 40%, and has lower energy consumption, so it is more green and energy-saving.

[0016] The present invention adds a cyclone collection mechanism in the system. The cyclone collection mechanism C3 is composed of a cyclone, a windproof collection valve, a vertical exhaust bag and a windproof collection valve, so as to better discharge clean air that meets the national standard requirements, so that the overall clean air volume exceeds 50%, and the secondary coarse particles in the dust can be collected again, and more than 20% of the secondary coarse particle materials can be recovered.

[0023] See also Figure 1 - Figure 3 A novel dust removal and powder control system includes a crusher body 1, a crusher rotor 2, a dust collection device 3, a powder selector 4, a vortex cyclone mechanism 5, a cyclone collection mechanism 7 and a bag dust collector 8. A crusher rotor 2 is arranged inside the crusher body 1, a dust collection device 3 is connected to the bottom end of the crusher body 1, a vortex cyclone mechanism 5 and a cyclone collection mechanism 7 are sequentially connected to the top of one side of the dust collection device 3, a powder selector 4 is connected to one side of the dust collection device 3, and a drainage fan 6 is arranged at the top of one side of the vortex cyclone mechanism 5. The top of the drainage fan 6 and the top of the cyclone collection mechanism 7 are both connected to a pipeline, a three-way valve is connected to the side of the powder selector 4 away from the dust collection device 3, and the powder selector 4 is connected to the pipeline and the bag dust collector 8 through the three-way valve.

[0025] A windproof collection valve 10 is provided at the bottom end of the vortex cyclone mechanism 5 close to the drainage fan 6, and the windproof collection valve 10 is used to recover coarse particle materials.

[0026] The top end of the drainage fan 6 is connected to the cyclone collection mechanism 7 through a pipeline.

[0027] The cyclone collection mechanism 7 includes a cyclone 11, a windproof collection valve 12, a vertical exhaust bag 13 and a windproof collection valve 14. The bottom ends of the windproof collection valve 12 and the bottom ends of the windproof collection valve 14 are both connected to the dust collection device 3, and a cyclone 11 is provided at the top of the windproof collection valve 12.

[0028] One side of the cyclone 11 is connected to the induced draft fan 6 .

[0029] The present invention retains the traditional configuration system of "crusher body 1+crusher rotor 2+powder selector 4+bag dust collector 8".

[0030] Adding a vortex cyclone mechanism 5 and a drainage fan 6 to form a vortex cyclone mechanism 5 and a drainage fan 6 combination (such as Figure 2 At the same time, in the vortex cyclone mechanism 5, a grid adjustment mechanism 9 and a windproof collection valve 10 are added to form a grid adjustment mechanism 9 and a windproof collection valve 10 combination (as shown in FIG. Figure 2 shown).

[0031] The grid adjustment mechanism 9 is used to effectively control the movement of high-speed air flow by adjusting the angle and gap of the grid plate, so as to achieve grading and stratification of coarse and fine particles in the dust.

[0032] The grid adjustment mechanism 9 separates the coarse particles in the dust, and the recovery rate can reach more than 40%.

[0033] The separated coarse particle materials enter the windproof collection valve 10 and are recycled into the finished product materials.

[0035] Add cyclone collection mechanism 7 (such as Figure 3 shown).

[0036] The cyclone 11 utilizes the vortex air + centrifugal force. Since the mass of the secondary coarse particles is greater than that of the air and fine particles, the secondary coarse particles move along the outer wall, and under the action of friction, they fall down at a reduced speed and enter the windproof collection valve 12, and then are recycled. The air and fine particles enter the vertical exhaust bag 13 through the discharge port.

[0037] After the air and fine particles enter the vertical exhaust bag 13 through the exhaust port, the clean air that meets the national standard requirements is exhausted by the fine holes of the vertical exhaust bag 13, and the exhaust volume can reach about 50% of the dusty air. (Note: The key to the vertical exhaust bag is the vertical layout, which avoids material blockage). The main function of the windproof collection valve 14 is to collect part of the sediment and recycle it.
