Description

Technical Field

[0001] This utility model relates to the field of carbon black dust removal technology, and in particular to a dust removal device for discharging carbon black raw material tanks. Background Technology

[0002] Carbon black, also known as carbon black, is an amorphous form of carbon. It is a light, loose, and extremely fine black powder that is a product of the incomplete combustion or thermal decomposition of organic matter (natural gas, heavy oil, fuel oil, etc.) under insufficient air conditions. Carbon black is a raw material for this product.

[0003] Carbon black production raw materials (such as petroleum cracking heavy oil and coal tar) are prone to generating high concentrations of dust during storage and transportation. These dust particles are fine and highly mobile, easily forming explosive mixtures. In enclosed containers, they can easily ignite and explode upon contact with static electricity or sparks. my country's "Integrated Emission Standard for Air Pollutants" requires carbon black dust emission concentrations to be ≤30 mg / m³. Traditional open unloading methods lead to dust dispersion, making it difficult to meet the stringent limits on fugitive particulate matter emissions under current environmental regulations.

[0004] To address this issue, a dust removal device for discharging carbon black raw material tanks was proposed, which has the advantages of both discharging and dust removal, thereby solving the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dust removal device for discharging carbon black raw material tanks.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a carbon black raw material tank discharge and dust removal device, comprising a raw material storage tank, the bottom of which is welded with a conical portion, and the bottom of the conical portion is connected to a discharge cylinder via a flange. A geared motor is fixedly installed at one end of the discharge cylinder, and an auger is fixed to the output end of the geared motor via a coupling. An outlet nozzle is provided at the end of the discharge cylinder away from the geared motor, and an expansion shell is welded to the top surface of the discharge cylinder. The lower part of the raw material storage tank... A dust collection box is fixed to the surface of the part by screws, and a dust collection fan is fixedly installed on the top surface of the dust collection box. A filter cover is installed at the air intake of the dust collection fan and is connected to the top surface of the dust collection box. A dust collection pipe is connected to the top surface of the expansion shell, and the upper end of the dust collection pipe is connected to the dust collection box. A water tank is set below the outlet of the discharge cylinder, and a dust settling box is welded to the top surface of the water tank. The dust settling box covers the outside of the outlet of the discharge cylinder, and the side of the dust settling box away from the discharge cylinder is an open structure.

[0007] As a further description of the above technical solution: a water pipe is connected to the side of the water tank, and a water pump is installed on the surface of the water pipe. One end of the water pipe is connected to a branch pipe, and several L-shaped spray branch pipes are arranged in pairs on the surface of the branch pipe. The bottom of the spray branch pipe passes through the dust settling box and is connected to a nozzle. A drain trough is welded and installed at the edge of the bottom surface of the inner side of the dust settling box corresponding to the nozzle. An activated carbon filter screen is embedded in the bottom of the drain trough, and the drain trough is connected to the water tank.

[0008] As a further description of the above technical solution: an arc-shaped mounting plate is welded and installed on the left side wall of the dust collection box, and the arc-shaped groove of the arc-shaped mounting plate fits against the outer wall of the raw material storage tank. A maintenance panel is fixed to the side of the dust collection box by quick-release screws.

[0009] As a further description of the above technical solution: a blowpipe is installed through the side of the filter cover, and a pulse valve is installed on the surface of the blowpipe, and the blowpipe is connected to an external high-pressure air source.

[0010] As a further description of the above technical solution: a gate valve is installed on the lower surface of the conical part, and a connecting nozzle with a flange is installed at the connection between the conical part and the discharge cylinder.

[0011] As a further description of the above technical solution: the dust collection box has a clearance hole on the side facing the discharge cylinder, and the inner diameter of the clearance hole matches the diameter of the discharge cylinder.

[0012] As a further description of the above technical solution: the bottom of the raw material storage tank is welded with several support legs, and the discharge cylinder is fixed between two adjacent support legs by bolts.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, a discharge cylinder is connected to the bottom flange of the raw material storage tank, and a strip-shaped expansion shell connected to the dust collection pipe is provided on the top surface of the discharge cylinder. By starting the dust collection fan at the top of the dust collection box, the air inside the dust collection box is drawn through the filter cover by the suction port of the dust collection fan, so that the inside of the dust collection box is in a negative pressure state. At this time, by starting the deceleration motor of the discharge cylinder, the deceleration motor drives the auger at its output end to rotate, so that the carbon black raw material discharged from the raw material storage tank is pushed out by the auger. The expansion shell can provide a space for dust particles to be contained during the discharge stage of the carbon black raw material, and is sucked into the dust collection box by the negative pressure of the dust collection pipe, which greatly reduces the dust emission phenomenon generated by the carbon black raw material tank during the discharge stage.

[0015] In this invention, a water tank and a dust suppression box are installed at the outlet of the discharge cylinder. By activating the water pump on the surface of the water pipe, water in the water tank is introduced into the distribution pipe through the water pipe, and then sprayed out by the two sets of spray branches on the surface of the distribution pipe. This causes the sprayed water to form a water curtain on the left and right sides inside the dust suppression box. Combined with the clearance hole on the back of the dust suppression box corresponding to the discharge cylinder, the dust suppression box provides a relatively sealed dustproof space for the discharge end of the discharge cylinder. The water curtain enables spray dust suppression treatment before the discharge cylinder discharges, thereby significantly reducing the air dust content in the discharge area of ​​the carbon black raw material tank.

A water tank 11 is provided below the outlet 17 of the discharge cylinder 4. A dust collection box 12 is welded to the top surface of the water tank 11. The dust collection box 12 covers the outer periphery of the outlet 17 of the discharge cylinder 4. The side of the dust collection box 12 away from the discharge cylinder 4 is an open structure. The expansion shell 6 can provide a space for dust particles during the discharge stage of carbon black raw materials, which is easy to remove dust and avoids the phenomenon of dust escaping caused by the traditional open discharge method. For the geared motor 5, the dust suction fan 9 and the water pump 14 described below, the control method of this utility model is to control them by manually starting and stopping the switch. The wiring diagram of the power components and the power supply are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring arrangement will not be explained in detail in this utility model.

[0025] In one embodiment, a water pipe 13 is connected to the side of the water tank 11, and a water pump 14 is installed on the surface of the water pipe 13. One end of the water pipe 13 is connected to a diversion pipe 15, and several L-shaped spray branch pipes 23 are arranged in pairs on the surface of the diversion pipe 15. The bottom of the spray branch pipe 23 passes through the dust settling box 12 and is connected to a nozzle 25. A drain trough 21 is welded and installed at the edge of the bottom surface of the inner side of the dust settling box 12 corresponding to the nozzle 25. An activated carbon filter screen 22 is embedded in the bottom of the drain trough 21, and the drain trough 21 is connected to the water tank 11. With the above structure, the dust settling box 12 provides a relatively sealed dustproof space for the discharge end of the discharge cylinder 4, reducing the interference of external dust on the discharge. Through several L-shaped spray branch pipes 23, the sprayed water forms a water curtain, and the spray dust settling treatment is achieved before the discharge cylinder 4 discharges, thereby significantly reducing the air dust content in the discharge area of ​​the carbon black raw material tank.

[0026] In one embodiment, an arc-shaped mounting plate 18 is welded and installed on the left side wall of the dust collection box 7, and the arc-shaped groove of the arc-shaped mounting plate 18 fits against the outer wall of the raw material storage tank 1. A maintenance panel is fixed to the side of the dust collection box 7 by quick-release screws. The arc-shaped mounting plate 18 facilitates the installation of the dust collection box 7, and the maintenance panel facilitates the disassembly and cleaning of the dust collection box 7.

[0027] In one embodiment, a blowpipe 19 is inserted into the side of the filter cover 10, and a pulse valve 20 is installed on the surface of the blowpipe 19. The blowpipe 19 is connected to an external high-pressure air source. By intermittently opening the pulse valve 20, the external high-pressure air source intermittently introduces high-pressure gas into the blowpipe 19, so that the blowpipe 19 blows the high-pressure gas onto the filter screen of the filter cover 10, thereby cleaning the filter screen of the filter cover 10. Regarding blowpipe dust removal, the contents not described in detail in this specification are prior art known to those skilled in the art and will not be elaborated further.

[0028] In one embodiment, a gate valve 3 is installed on the lower surface of the conical part 2, and a connecting nozzle with a flange is installed at the connection between the conical part 2 and the discharge cylinder 4. The gate valve 3 facilitates material discharge, and the connecting nozzle with the flange facilitates the connection between the conical part 2 and the discharge cylinder 4.

[0029] In one embodiment, the dust collection box 12 has a clearance hole 24 on the side facing the discharge cylinder 4, and the inner diameter of the clearance hole 24 matches the diameter of the discharge cylinder 4. By setting the clearance hole 24, the outlet nozzle 17 of the discharge cylinder 4 can extend to the inside of the dust collection box 12, providing a relatively sealed dustproof space for the discharge end of the discharge cylinder 4.

[0030] In one embodiment, the bottom of the raw material storage tank 1 is welded with several support legs, and the discharge cylinder 4 is fixed between two adjacent support legs by bolts. The support legs facilitate the support of the raw material storage tank 1 and provide an installation structure for the discharge cylinder 4.

[0031] Working principle:

[0032] In use, first open the gate valve 3 at the bottom of the conical part 2 to allow the carbon black material in the raw material storage tank 1 to enter the discharge cylinder 4. During this process, the dust collection fan 9 at the top of the dust collection box 7 is started, causing the air in the suction port of the dust collection fan 9 to be drawn from the inside of the dust collection box 7 through the filter cover 10, making the inside of the dust collection box 7 a negative pressure state. As the reduction motor 5 of the discharge cylinder 4 is started, the reduction motor 5 drives the auger 16 at its output end to rotate, so that the carbon black material discharged from the raw material storage tank 1 is pushed out by the auger 16. The expansion shell 6 can provide a space for dust particles to be contained during the discharge stage of the carbon black material, and the dust particles are sucked into the dust collection box 7 by the negative pressure of the suction pipe 8, realizing... During the dust removal process of carbon black raw material discharge, the water pump 14 on the surface of the water pipe 13 is activated to cause the water in the water tank 11 to be introduced into the diversion pipe 15 through the water pipe 13, and then sprayed out by the two sets of spray branch pipes 23 on the surface of the diversion pipe 15. This causes the sprayed water to form a water curtain on the left and right sides inside the dust settling box 12. Combined with the clearance hole 24 opened on the back of the dust settling box 12 corresponding to the discharge cylinder 4, the dust settling box 12 provides a relatively sealed dustproof space for the discharge end of the discharge cylinder 4. With the water curtain, the spray dust removal treatment is achieved before the discharge cylinder 4 discharges, reducing the air dust content in the discharge area of ​​the carbon black raw material tank and achieving low dust discharge of carbon black raw materials.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
