Description

Technical Field

[0001] The utility model relates to the technical field of dust treatment, in particular to a dust treatment system. Background Art

[0002] In the process of rubber processing, it is necessary to go through processes such as plastication, mixing, calendering or extrusion (i.e. extrusion), molding and vulcanization. Each process has different requirements for various products and a number of auxiliary operations. In the process of rubber processing, dust is often generated. The dust floats around the processing area, polluting the surrounding environment, seriously affecting the health of workers, and may even cause explosions. Therefore, dust collection equipment needs to be installed at each workstation to prevent dust from floating in the production workshop.

[0003] For multiple workstations in a workshop, the existing technology often sets up a separate dust treatment device for each workstation, and configures a suction fan for each workstation, which takes up too much space. There are also some dust treatment systems that set up dust hoods for each workstation, and then connect the dust hoods through pipes, and then use the same exhaust fan equipment to exhaust the pipes to achieve the effect of collecting dust from multiple workstations at the same time. However, with such a design, when the fan is turned on, the dust hoods on each workstation will work at the same time. When some workstations are not in use, their corresponding dust hoods will also perform suction. Due to the dispersion of wind force by a large number of dust hoods, there may be a problem of insufficient wind force for the workstations that need dust collection, resulting in poor dust collection effect.

[0014] As a further improvement of the above technical solution, the dust collection assembly further includes a weight block connected to the lower end of the dust curtain. The weight block can keep the dust curtain drooping, and during the dust collection process, the dust curtain can be prevented from being sucked into the workstation in the dust collection space and causing a safety accident.

[0015] As a further improvement of the above technical solution, the filter assembly includes a compressor, a conveying chamber, a dust hopper, a support frame and an adsorption filter.

[0033] Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. The various technical features in the utility model can be combined interchangeably without conflicting with each other.

[0034] Reference Figures 1 to 5 The embodiment of the utility model proposes a dust treatment system, which can collect dust from a single or multiple workstations and has a good dust collection effect.

[0035] In this embodiment, the dust treatment system includes a dust collecting component 100, a dust collecting pipe 200, a filter component 300 and a suction fan 400. The dust collecting component 100 is connected to the inlet of the dust collecting pipe 200, the outlet of the dust collecting pipe 200 is connected to the inlet of the filter component 300, the inlet of the suction fan 400 is connected to the outlet of the filter component 300, and the outlet of the suction fan 400 is connected to the outdoors. When the suction fan 400 is started, the dust collecting component 100 can collect dust from the indoor workstations, and the dust enters the dust collecting pipe 200 through the dust collecting component 100, and after being filtered by the filter component 300, the clean air is discharged to the outdoors through the suction fan 400.

[0036] Specifically, the dust collecting assembly 100 is provided with a plurality of Figure 2Each dust collecting assembly 100 includes a dust collecting hood 110, a connecting pipe 120, a diverter fan 130 and a valve 140. The dust collecting hood 110 is provided with a dust collecting chamber, the upper and lower ends of the dust collecting chamber are both opened, the lower end of the connecting pipe 120 is connected to the upper end of the dust collecting hood 110, the diverter fan 130 is arranged in the connecting pipe 120, the air inlet of the diverter fan 130 is arranged downward, and the valve 140 is arranged at the upper end opening of the dust collecting hood 110. When the valve 140 is opened, the dust collecting chamber is connected to the connecting pipe 120; when the valve 140 is closed, the dust collecting chamber and the connecting pipe 120 are blocked.

[0037] It is understandable that the arrangement of the dust collection duct 200 can be adjusted according to the specific location of each workstation in the workshop, and one or more dust collection assemblies 100 can be correspondingly arranged at each workstation.

[0038] When one or several workstations need to be used, dust is collected for the workstations to be used, and the shunt blower 130 and valve 140 in the dust collection assembly 100 corresponding to the one or several workstations are turned on, and the shunt blower 130 and valve 140 in the dust collection assembly 100 corresponding to other unused workstations are turned off. In the dust collection assembly 100 with the shunt blower 130 and valve 140 turned on, dust is sucked into the dust collection hood 110 from the lower end of the dust collection hood 110 along with the air, and enters the dust collection duct 200 through the connecting pipe 120, and flows through the dust collection duct 200 to the filter assembly 300 for filtration and collection.

[0039] It is understandable that the split flow fan 130 can improve the suction efficiency of air and dust and improve the dust collection effect. Since the split flow fan 130 in the corresponding dust collection component 100 can be turned on or off, the use of the split flow fan 130 can be reduced, thereby reducing energy consumption.

[0040] It can be understood that since each dust collecting component 100 is provided with a valve 140, for the unused workstation, the valve 140 of the corresponding dust collecting component 100 is closed, which can reduce the dispersion of wind force in the dust collecting duct 200, allowing the wind force of the dust collecting component 100 at other workstations to meet the dust collection requirements and improve the dust collection effect.

[0041] In this embodiment, the side wall of the dust collecting cover 110 is inclined, and the cross section of the dust collecting cover 110 gradually increases from top to bottom and is tapered. Such a configuration can be more conducive to the inhalation of dust into the dust collecting cover 110, thereby improving the dust inhalation effect.

[0042] In some embodiments, the dust collection assembly 100 also includes a control switch 150, and the valve 140 and the diversion fan 130 are electrically connected to the control switch 150 respectively. The operator can directly control the opening or closing of the corresponding valve 140 and the diversion fan 130 through the control switch 150.

[0043] In this embodiment, the control switch 150 is arranged below the dust collecting cover 110. Specifically, the control switch 150 extends to the bottom of the dust collecting cover 110 through an electric wire, and such arrangement is more conducive to the operation of the operator.

[0044] In some embodiments, the dust collection assembly 100 further includes a dust curtain 160, the upper end of which is connected to the outer periphery of the dust collection cover 110 and extends downward, and the dust curtain 160 and the dust collection cover 110 together form a dust collection space.

[0045] It is understandable that the workstation that needs to collect dust is set in the dust collection space. By setting the dust-proof curtain 160, the side of the workstation can be surrounded to prevent dust from flying, and the dust collection effect of the dust collecting hood 110 can be further improved.

[0046] In some embodiments, the dust collection assembly 100 also includes a weight block, which is connected to the lower end of the dust curtain 160, allowing the dust curtain 160 to remain drooping. During the dust collection process, the dust curtain 160 can be prevented from being sucked into the workstation in the dust collection space and causing a safety accident.

[0047] In this embodiment, the dust curtain 160 is composed of a plurality of strip-shaped plastic belts, and the upper end of the plastic belt is connected to the dust collecting cover 110. The operator can enter the dust collecting space between any two plastic belts to facilitate the use of equipment in the workstation in the dust collecting space.

[0048] It is understandable that the length of the plastic belt can be adjusted according to the actual structure of the equipment in the workstation. For example, for equipment equipped with a conveyor belt, the conveyor belt needs to extend out of the dust collection space, and the length of the plastic belt above the conveyor belt can be shortened to facilitate the conveyor belt to transport items.

[0049] In some embodiments, the filter assembly 300 includes a compressor 310, a conveying chamber 320, a dust collecting hopper 330, a support frame 340 and an adsorption filter 350. Figure 3 and Figure 4 .

[0050] The upper end of the support frame 340 is connected to the outer wall of the dust hopper 330, and can provide support for the dust hopper 330 and other components, and the lower end thereof is grounded. The upper end of the dust hopper 330 is connected to the outlet of the dust collecting duct 200, and the lower end is connected to the conveying chamber 320. The dust flowing out of the dust collecting duct 200 with the air can enter the dust hopper 330, and most of the dust flows downward to the conveying chamber 320 under the action of gravity. A dust port is provided on the side wall of the conveying chamber 320, and the compressor 310 is connected to the conveying chamber 320 and is arranged toward the dust port. The compressor 310 can blow compressed air to the dust port, so that the dust in the conveying chamber 320 is blown out from the dust port to facilitate the collection of dust.

[0051] The inlet of the adsorption filter 350 is connected to the side wall of the dust hopper 330, and the outlet of the adsorption filter 350 is connected to the inlet of the suction fan 400. The air flowing out of the dust collection duct 200 can enter the dust hopper 330, and enter the suction fan 400 after being adsorbed and filtered by the adsorption filter 350. The adsorption filter 350 can adsorb the dust remaining in the air to prevent the dust from entering the suction fan 400.

[0052] In this embodiment, the adsorption filter 350 adsorbs dust in the air through activated carbon.

[0053] In this embodiment, the dust hopper 330 and the adsorption filter 350 are connected via an air duct 390, the upper end of the air duct 390 is connected to the dust hopper 330, and the lower end of the air duct 390 is connected to the adsorption filter 350, and the adsorption filter 350 can be placed stably on the ground.

[0054] It can be understood that the connection position between the air duct 390 and the dust hopper 330 is located at the upper end of the dust hopper 330, so as to increase the distance between the air outlet position and the dust outlet position of the dust hopper 330, reduce the outflow of dust from the connection position between the air duct 390 and the dust hopper 330, and reduce the amount of dust entering the adsorption filter 350, so as to improve the adsorption performance and service life of the adsorption filter 350.

[0055] In this embodiment, the bottom surface of the dust hopper 330 is tilted downward from the periphery to the middle, an opening is provided at the middle of the lower end of the dust hopper 330 for dust to pass through, and the conveying chamber 320 is installed at the middle of the lower end of the dust hopper 330. In this way, dust can slide down along the bottom surface of the dust hopper 330 into the conveying chamber 320.

[0056] In some embodiments, the filter assembly 300 also includes an air hammer, which is installed on the outer wall of the dust hopper 330 and can provide vibration power to the inclined bottom surface of the dust hopper 330, so that the dust inside the dust hopper 330 can fall more smoothly along the bottom surface of the dust hopper 330 to the conveying chamber 320, thereby preventing the dust from sticking to the inner wall of the dust hopper 330.

[0057] In this embodiment, the compressor 310 is a variable frequency compressor 310 .

[0058] In some embodiments, the filter assembly 300 further includes a raised platform 360, the upper end of which is connected to the support frame 340, and the lower end of which is grounded. The raised platform 360 can be provided to lift the entire support frame 340, the dust hopper 330 connected to the support frame 340, the compressor 310 connected to the dust hopper 330, and other components upward by a certain distance, so that there is a sufficient distance between the lower end of the dust hopper 330 and the ground, so that the operator can enter under the dust hopper 330, which is conducive to collecting the discharged dust at the outlet position of the conveying chamber 320.

[0059] In some embodiments, the filter assembly 300 further includes a dust bag 370 for collecting discharged dust. The dust bag 370 is wrapped around the dust port of the conveying chamber 320 and can directly load the dust discharged from the dust port to facilitate subsequent recycling of the dust.

[0060] In this embodiment, the filter assembly 300 further includes a placement table 380 , which is disposed below the dust hopper 330 , and the dust bag 370 is disposed on the placement table 380 , and the dust bag 370 is detachably connected to the lower end of the dust hopper 330 . Figure 3 is a schematic diagram of the structure of the filter assembly 300 with the dust bag 370 installed. Figure 4 It is a schematic diagram of the structure of the filter assembly 300 with the dust bag 370 removed.

[0061] It is understandable that the dust bag 370 is connected to the lower end of the dust hopper 330, and the dust hopper 330 provides an installation position for the dust bag 370, so that workers do not need to support the dust bag 370 for a long time, thereby reducing the labor intensity of the workers. The placement table 380 provides an upward support force for the bottom of the dust bag 370, thereby reducing the burden of the dust bag 370 on the dust hopper 330 and preventing the dust hopper 330 from being damaged.

[0062] The connection between the dust bag 370 and the dust hopper 330 is detachable. When the dust bag 370 is full of dust, the worker disassembles and takes out the dust bag 370 from under the dust hopper 330, and after packaging, it can be transferred to a recycling point for recycling.

[0063] In this embodiment, a hook structure is provided at the lower end of the dust hopper 330, and a hanging ear is provided at the upper end of the dust bag 370. The dust bag 370 is directly hung on the hook structure of the dust hopper 330 through the hanging ear to achieve a detachable connection between the dust bag 370 and the dust hopper 330.

[0064] In some embodiments, the dust treatment system further includes an exhaust pipe 500, the lower end of which is connected to the outlet of the suction fan 400, and the exhaust pipe 500 is extended upward and opened upward. It is understandable that the exhaust pipe 500 is provided to guide the filtered air to be discharged upward.

[0065] In some embodiments, the dust handling system further includes a support pipe 600, the upper end of the support pipe 600 is connected to the middle of the exhaust pipe 500, and the lower end of the support pipe 600 is connected to the ground. It is understandable that the support pipe 600 can provide support force for the exhaust pipe 500, reduce the pressure of the exhaust pipe 500 on the suction fan 400, and prevent the exhaust pipe 500 from tipping over.

[0066] In some embodiments, the dust handling system also includes a rain cap 530, which includes an umbrella-shaped structure and a connecting rod, the lower end of the connecting rod is connected to the upper end of the exhaust pipe 500, the upper end of the connecting rod is connected to the umbrella-shaped structure, and the umbrella-shaped structure covers the upper end opening of the exhaust pipe 500.

[0067] It is understandable that there is a distance between the umbrella-shaped structure and the upper end of the exhaust pipe 500, and the air can be discharged from between the umbrella-shaped structure and the upper end of the exhaust pipe 500, and the setting of the umbrella-shaped structure will not have too much impact on the discharge of air. In rainy, snowy and other weather environments, the umbrella-shaped structure can prevent rainwater and snow water from entering from the upper end of the exhaust pipe 500, thereby preventing rainwater and snow water from damaging the suction fan 400.

[0068] In this embodiment, the exhaust pipe 500 is provided with an inclined section 510 at the lower portion and a vertical section 520 at the upper portion. The lower end of the vertical section 520 is connected to the upper end of the inclined section 510, and the lower end of the inclined section 510 is connected to the suction fan 400. The support pipe 600 is connected to the connection position between the inclined section 510 and the vertical section 520, and the support pipe 600 and the vertical section 520 are located on the same straight line.

[0069] Such an arrangement can further prevent rainwater and snow water from entering the suction fan 400. A small amount of rainwater and snow water that enters the exhaust pipe 500 can enter the support pipe 600 from the vertical section 520, flow through the support pipe 600 to the ground, and be absorbed by the ground.

[0070] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments.
