Description

Technical Field

[0001] The utility model relates to the technical field of open mixing mills, in particular to a dust removal device for open mixing mills. Background Art

[0002] Mixing is the process of using a rubber mixer to evenly disperse softeners, stearic acid, carbon black and other compounding agents in raw rubber or plasticizing to make mixed rubber through mechanical action. It is the most important production process in rubber processing. Rubber mixers are mainly divided into two types according to their structure: open type and closed type, and open mixer is the abbreviation of open mixer. The open mixer generates shear force to mix the rubber by two rollers moving relative to each other at different speeds. Due to its open structure, various powders mixed are easy to fly everywhere, which seriously affects the air quality of the production workshop and has the hidden danger of dust explosion, and also endangers the health of operators.

[0003] At present, for the dust pollution problem in the mixing process, an air intake pipe or an exhaust fan is generally used to take the flying dust away from the mixing mill. The exhaust fan can only quickly disperse the high-concentration dust in the mixing mill into the surrounding air. Although it can solve the problem of high local dust concentration in the mixing mill, it will expand the scope of dust pollution in the workshop, so it can only be used temporarily. In addition, many harmful gases such as sulfur compounds and dust pollutants will be generated during the mixing process. These substances are very harmful to human health. Therefore, there is an urgent need for a dust removal device that can be used for a long time, has a good dust removal effect, and can also handle harmful gases to reduce the harm to human health.

[0024] Example

[0025] like Figure 1 As shown, a dust removal device for an open mill includes an open mill body 7, a dust collection assembly is provided above the open mill body 7, a dust collection and processing assembly is provided on one side of the open mill body 7, and the dust collection assembly includes a dust hood 2, a baffle 3, a dust curtain 5, and a counterweight rod 6. Hooks 18 that cooperate with the counterweight rod 6 are provided on both sides of the dust curtain 5. The baffle 3 is located around the top of the open mill body 7, the dust hood 2 is located above the baffle 3, and the dust hood 2 and the baffle 3 cooperate to enclose a sealed space at the top of the open mill body 7 to reduce the pollution range of the workshop dust.

[0026] An opening is provided on the baffle plate 3 corresponding to the feed port 17 of the open mill body 7, and a dust curtain 5 is provided at the opening. A counterweight rod 6 is provided at the bottom of the dust curtain 5, and hooks 18 corresponding to the counterweight rod 6 are provided on the baffle plates 3 on both sides of the dust curtain 5. The inner side of the dust curtain 5 is in close contact with the outer surface of the baffle plate 3. The dust curtain 5 is made of soft material. When it is necessary to feed the open mill, the counterweight rod 6 at the bottom of the dust curtain 5 is lifted to the hook 18, and the hook 18 hooks the two ends of the counterweight rod 6, and the dust curtain 5 is folded to leave space for feeding, which is convenient for feeding. After feeding, the counterweight rod 6 is immediately lowered to cover the opening to reduce the range of dust flying. The function of the counterweight rod 6 is to prevent the dust curtain 5 from being sucked by the exhaust fan 8 when sucking dust, so as to prevent the dust curtain 5 from being unable to cover the opening under the action of suction. Under the action of the weight of the counterweight rod 6 itself, the dust curtain 5 can block the opening to the greatest extent to prevent the expansion of the range of dust flying.

[0027] The dust cover 2 is provided with a filter material layer 1 inside. The filter material layer 1 can be an activated carbon filter material layer 1. The coconut shell activated carbon particles have a well-developed pore structure, a large specific surface area, strong adsorption performance, stable chemical properties, and are easy to regenerate. While adsorbing dust, it can also purify other pollutants in the air and improve the dust removal effect. The filter material layer 1 is detachably connected to the dust cover 2. The dust cover 2 is provided with a rubber sealing ring 21 (such as Figure 3 The outer side of the filter material layer 1 is provided with a convex edge 22, and the inner side of the rubber sealing ring 21 is provided with a groove 20 corresponding to the convex edge 22. When installed, the convex edge 22 of the filter material layer 1 is located in the groove 20. By utilizing the elastic performance of the rubber sealing ring 21, the filter material layer 1 can be disassembled through the cooperation between the convex edge 22 and the groove 20, which is convenient for replacing the filter material layer 1 (as shown in FIG. Figure 4 shown).

[0028] The dust collection and processing assembly includes an exhaust fan 8 and a dust collection box 11 . A liquid storage box 15 is provided above the dust collection box 11 , and a spray head 13 , a collection bucket 12 , and a waste liquid tank 10 are provided inside the liquid storage box 15 .

[0029] An exhaust fan 8 is provided between the mixing mill body 7 and the dust collecting box 11, and a pipe 19 connected to the exhaust fan 8 is provided on the top of the dust hood 2 and one side of the baffle 3, and the air outlet of the exhaust fan 8 is connected to the dust collecting box 11 through a connecting pipe 9. The dust above the feed port 17 of the mixing mill body 7 is sucked away into the dust collecting box 11 through the dust hood 2, and the dust near the feed port 17 is sucked into the exhaust fan 8 through the pipe 19 on the baffle 3 and enters the dust collecting box 11 for treatment.

[0030] The liquid storage tank 15 is connected to the dust collecting box 11 through the liquid infusion pipe 16. A liquid dispensing pipe 14 is provided at the bottom of the liquid infusion pipe 16. A plurality of evenly distributed spray heads 13 are provided at the bottom of the liquid dispensing pipe 14. The spray heads 13 are respectively connected to the liquid dispensing pipe 14. A collecting bucket 12 is provided below the spray head 13. A communicating waste liquid tank 10 is provided at the bottom of the collecting bucket 12. The exhaust fan 8 absorbs the harmful sulfide gas generated during the rubber mixing process while sucking dust. The harmful sulfide gas enters the dust collecting box 11 together with the dust. The liquid storage tank 15 is provided with a liquid for absorbing harmful sulfide gas. The liquid enters the liquid dispensing pipe 14 in the dust collecting box 11 through the liquid infusion pipe 16 and then sprays through the spray head 13. The dust and harmful sulfide gas absorbed by the exhaust fan 8 enter the dust collecting box 11. Under the action of spraying, the harmful gas is absorbed and the dust is wetted. The wet dust and the liquid for absorbing harmful gas enter the waste liquid tank 10 through the collecting bucket 12 for centralized treatment.

[0031] like Figure 2 As shown, a perspective window 4 is provided on the baffle plate 3 on one side of the top of the mixing mill body 7 to facilitate observation during operation.

[0032] When in use, hook the counterweight rod 6 with the hook 18, add material at the opening, and quickly put down the counterweight rod 6 after adding material. The dust flying above the feed port 17 of the open mill body 7 is filtered through the filter material layer 1 and then enters the dust collecting box 11. The dust around the feed port 17 of the open mill body 7 enters the dust collecting box 11 through the pipe 19 on the side of the baffle 3. The spray head 13 sprays the dust and harmful gas entering the dust collecting box 11, and enters the waste liquid tank 10 through the collecting bucket 12 for treatment.

[0033] Therefore, the utility model adopts the above-mentioned dust removal device for the mixing mill to reduce the scope of dust pollution in the workshop, can be used for a long time, improve the dust removal effect, and can also process harmful gases to reduce the harm to human health.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
