[0024] As shown in the drawings, a special dustproof device for the outlet of a slag remover comprises: Figures 1-2

[0025] (1) The outer shell 1 is a hollow structure with an open end, which is used to connect with the outlet of the slag remover. The outer shell 1 is made of stainless steel, which is firm and corrosion-resistant, and can withstand a certain impact force and the influence of harsh environment. The shape of the outer shell 1 can be designed according to the shape of the outlet of the slag remover, and it is commonly rectangular or circular.

[0026] (2) The dust collecting cover 2 is arranged inside the outer shell 1 near one side of the outlet of the slag remover, and is funnel-shaped. The dust suction port (large end) of the dust collecting cover 2 faces the direction of the outlet of the slag remover, which can preliminarily gather the waste slag and dust discharged from the slag remover, and facilitate the collection and treatment of the dust. The dust collecting cover 2 is made of plastic-coated steel plate, which can prevent the waste slag from causing rapid wear, and facilitate the sliding of the dust.

[0027] (3) The dust guide channel 3 is connected to the outlet end (small end) of the dust collecting cover 2, and is "V"-shaped. The moving direction of the dust in the dust guide channel 3 is first downward and then upward. The downward inclined pipeline of the dust guide channel 3 is the settling section 9, which is in communication with the dust collecting cover 2, and can guide the gathered dust to slide downward by gravity. The inside of the dust guide channel 3 can be provided with a smooth ceramic lining to reduce the adhesion of the dust. The manhole door 8 is arranged at the turning position of the dust guide channel 3, which is used to clean and discharge the deposited dust layer and accumulated water in the pipeline.

[0028] (4) The dust collecting box 4 is located below the end of the settling section 9, and is used to collect the dust that slides downward by gravity. The dust collecting box 4 can be detached from the whole device, which is convenient for regular cleaning of the dust. The top of the dust collecting box 4 is provided with a sealing cover to prevent the dust from scattering again during the collection process.

[0029] (5) The air filter assembly 5 is arranged at the end of the upward inclined pipeline of the dust guide channel 3. The air filter assembly 5 includes a coarse filter screen, an activated carbon filter screen and a high-efficiency filter screen arranged along the moving direction of the dust, which can filter the dust-containing air escaping from the outlet of the slag remover, so that the discharged air meets the environmental protection standard and reduces the pollution to the environment.

[0030] ​(6), the air induction fan 6: installed in one side of the outer shell 1, the air induction fan 6 air inlet is connected with the dust guide channel 3 outlet, the air induction fan 6 air outlet is connected with the outside, the air induction fan 6 can accelerate the air flow in the outer shell 1, so that the dust is more easily sucked into the dust guide channel 3 and discharged after being filtered by the air filter assembly 5, ensure that the internal pressure of the outer shell 1 is balanced, facilitate the dustproof work to continue efficiently.

[0031] (7), the honeycomb plate 7: set the dust suction port of the dust collecting hood 2, the arc shape is recessed into the dust collecting hood 2, as shown in Figure 2 The honeycomb plate 7 is uniformly provided with a plurality of through holes, and the local air flow rate of the through hole is accelerated, which is conducive to the dust rising and being sucked into the inside of the dust collecting hood 2. The hollow rate of the honeycomb plate 7 is 20%-30% of the area of the entire honeycomb plate 7, so that a local negative pressure chamber is formed in the dust collecting hood 2, the flow rate of the dust sucked into the dust collecting hood 2 is effectively improved, the dust removal effect is effectively improved, and the situation that the dust is dispersed due to the too low flow rate of the dust is reduced. The honeycomb plate 7 is detachably connected with the dust collecting hood 2 through the reinforcing rib 10.

[0032] The working process of the device will be described in detail in combination with the drawings in the embodiments.

[0033] 1. Installation process: first, the open end of the outer shell 1 is tightly fixed with the slag removal machine outlet by welding, bolt connection or flange connection and other appropriate methods, to ensure that the connection is sealed well and prevent dust from escaping from the gap.

[0034] Next, the air induction fan 6 is installed on one side of the outer shell 1 according to the designed position, and the electrical circuit and other related connections are completed, to ensure that the air induction fan 6 can operate normally.

[0035] Then, check whether the connection between the dust guide channel 3, the dust collecting hood 2 and the dust collecting box 4 is stable, to ensure that the dust can smoothly fall from the dust collecting hood 2 into the dust collecting box 4 through the dust guide channel 3.

[0036] Finally, the air filter assembly 5 is installed at the outlet of the dust guide channel 3, to ensure that it is firmly installed and tightly sealed.

[0037] 2. Working process: when the slag removal machine starts to work and discharges slag, the waste slag and the dust generated are first introduced into the dust collecting cover 2 in the outer shell 1, the dust collecting cover 2 and the honeycomb plate 7 gather them, the dust and part of the small particle waste slag slide along the inclined dust guide channel 3 into the dust collecting box 4 under the action of gravity and the suction force generated by the induced draft fan 6 and are collected. The remaining dust-containing air in the outer shell 1 flows to the air outlet of the dust guide channel 3 under the action of the induced draft fan 6, when passing through the air filter assembly 5, the dust in the air is intercepted and filtered by each layer of filter screen, and finally the clean air is discharged to the outside environment through the air outlet of the dust guide channel 3, so that the good dustproof effect of the slag removal machine outlet is realized. After being used for a period of time, the slag removal machine can be regularly closed, the dust collecting box 4 is disassembled and the collected dust is cleaned, and the filter screen in the air filter assembly 5 is checked and replaced, so that the dustproof performance of the device is maintained.

[0038] The above is only a preferred embodiment of the utility model creation, and is not used to limit the utility model creation, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model creation should be included in the protection scope of the utility model creation.
