Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to an explosion-proof dust collector. Background Art

[0002] Explosion-proof dust collectors are increasingly used in industries involving flammable and explosive dust, such as chemical processing, mineral processing, grain manufacturing, metalworking, spraying, sandblasting, and polishing. These industries generate large amounts of combustible dust, such as flour dust, aluminum powder, and magnesium powder, during production. The use of explosion-proof dust collectors effectively reduces explosion risks and ensures production safety. With businesses increasingly prioritizing production safety and the strengthening of national environmental protection and safety regulations, market demand for explosion-proof dust collectors is on the rise. More and more companies are recognizing the importance of explosion-proof dust collectors and are actively purchasing and installing them.

[0003] The principle of an explosion-proof dust collector is typically to install a filter cartridge, which filters air through the filter cartridge and separates combustible dust from the air through physical interception. Existing explosion-proof dust collectors often install the filter cartridge vertically inside the dust collector, making replacement and maintenance relatively inconvenient. During dust removal, if a combustible mixture forms inside the dust collector due to dust accumulation and ignites, it may cause excessive pressure inside the dust collector, causing it to rupture and damage. Therefore, an explosion-proof dust collector is proposed. Utility Model Content

[0004] The main purpose of the utility model is to provide an explosion-proof dust collector, which solves the problem that the filter cartridge of the existing explosion-proof dust collector is often installed vertically inside the dust collector, which is inconvenient to replace and maintain. When the explosion-proof dust collector is removing dust, when a combustible mixture is formed inside the dust collector due to dust accumulation and other reasons and is ignited, the pressure inside the dust collector may be too high, causing the dust collector to rupture and damage.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] 14. The filter bag of claim 13, wherein the filter bag is mounted on a plurality of support members, each of which is adapted to engage with a plurality of filter cartridges and a plurality of filter cartridges connected thereto.

[0007] Furthermore, an air inlet is fixedly connected to the upper side of the box body, an ash hopper is fixedly connected to the lower side of the box body, a dust collecting bucket is movably installed below the ash hopper, a base is abutted against the lower side of the dust collecting bucket, a support bracket is fixedly connected to the upper side of the base, the upper side of the support bracket is fixedly connected to the box body, and one side of the support bracket is fixedly connected to an electrical box mounting plate.

[0008] Furthermore, a connecting air duct is fixedly connected to one side of the box body, a thermistor sensor is fixedly installed on the inner side of the connecting air duct, a fan is fixedly connected to one side of the connecting air duct, and a muffler is fixedly connected to the upper output end of the fan.

[0009] Furthermore, two explosion relief plates are fixedly installed at equal distances on both sides of the box.

[0010] Furthermore, connecting ball valves are fixedly installed on both sides of the upper part of the connecting air duct, a pressure regulating valve is fixedly connected to one side of the supporting bracket, the air outlets of the two connecting ball valves are fixedly connected to hoses, the two hoses are fixedly connected to the pressure regulating valves, and a negative pressure differential gauge is installed on the outside of the box.

[0011] Furthermore, a clean room door is fixedly installed on one side of the box body, a cooling nozzle is fixedly installed on the upper side of the box body, and two slow flow plates are fixedly connected to the inner side of the box body at equal distances, and the inner sides of the two slow flow plates are fixedly connected to partitions.

[0012] Furthermore, an air bag tube is fixedly installed on the outer side of the partition, and six pulse valves are fixedly installed at equal intervals on the outer side of the air bag tube, and the nozzles of the six pulse valves are respectively aligned with the positions of the six venturi tubes.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The utility model provides a skeleton pull rod, which facilitates the replacement and maintenance of the filter cartridge and improves work efficiency. When in use, the clean room door is opened and the fixing bolts are removed. At this time, the filter cartridge cover can be pulled outward, and the filter cartridge cover drives the skeleton pull rod and the filter cartridge to leave the box from the installation hole. At this time, the filter cartridge can be repaired and replaced. At the same time, the filter cartridge is installed in the box at an angle, so that the air can contact the filter cartridge more fully, thereby improving the filtration efficiency. Through such a setting, the replacement and maintenance of the filter cartridge is convenient, and the work efficiency is improved.

[0015] 2. The utility model provides a cooling nozzle to facilitate automatic cooling of the dust collector and prevent dust from spontaneous combustion and explosion. When the thermistor sensor senses that the air temperature in the box is too high, the dust collector automatically starts the cooling nozzle, which sprays water into the box to cool the air and prevent dust combustion. This setting facilitates automatic cooling of the dust collector and prevents dust from spontaneous combustion and explosion.

[0016] 3. The utility model provides a pressure-regulating valve to facilitate automatic pressure release, avoiding the normal operation of the dust collector being affected by excessive pressure. When the pressure in the box is too high, the pressure is transmitted to one side of the pressure-regulating valve through the air through the connecting ball valve and the hose. The pressure-regulating valve adjusts the opening according to the air pressure to control the flow rate, so that the pressure in the box is maintained at a preset value. Through such a setting, automatic pressure release is facilitated, avoiding the normal operation of the dust collector being affected by excessive pressure.

[0017] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-Figure 5 As shown, an explosion-proof dust collector includes a box body 1, six mounting holes are equidistantly opened on the outside of the box body 1, filter cartridges 16 are movably sleeved in the six mounting holes, filter cartridge covers 22 are fixedly connected to the outsides of the six filter cartridges 16, the inner sides of the six filter cartridge covers 22 are all against the outer wall of the box body 1, the outer sides of the six filter cartridges 16 are movably sleeved with partitions 18, the sides of the partitions 18 are fixedly connected to the inner wall of the box body 1, the inner sides of the six filter cartridge covers 22 are fixedly connected to mounting plates, and three skeleton tie rods 19 are equidistantly installed on the inner sides of the six mounting plates, and three skeleton tie rods 19 are arranged in a group on each mounting plate, and six groups of skeleton tie rods 19 are arranged in a group. 9 are movably mounted with Venturi tubes 20 on the outside, the inner sides of the six Venturi tubes 20 are all against the partition 18, and the outer sides of the eighteen skeleton tie rods 19 are all threadedly connected with fixing bolts 21. Three adjacent fixing bolts 21 form a group, and the inner sides of the six groups of fixing bolts 21 are respectively against the six Venturi tubes 20. By adopting the above technical solution, a number of support rings are fixedly sleeved at equal distances on the outer side of each group of skeleton tie rods 19. The outer sides of these support rings are against the inner walls of the adjacent filter cartridges 16, which can support the filter cartridges 16 and keep the filter cartridges 16 in the maximum filtering state. At the same time, the support rings can strengthen the structural strength of each group of skeleton tie rods 19;

[0026] One end of the outer side of the skeleton tie rod 19 is processed by a tapping process, and one end of the skeleton tie rod 19 can be threadedly connected to the fixing bolt 21;

[0027] When the filter cartridge 16 is sleeved in the partition 18, a sealing device is installed on the side of the venturi tube 20 to seal and fix the side of the filter cartridge 16, so that the air can pass through the partition 18 and enter the venturi tube 20 only after being filtered by the filter cartridge 16;

[0028] When the fixing bolt 21 is threadedly connected to one end of the skeleton tie rod 19, the fixing bolt 21 drives the side of the venturi tube 20 to abut against the partition 18. At this time, the fixing bolt 21 is limited so that the filter cartridge 16 will not fall out of the mounting hole.

[0029] A sealing rubber ring is installed inside the filter cartridge cover 22 to prevent air leakage.

[0030] like Figure 1-Figure 3 As shown, an air inlet 2 is fixedly connected to the upper side of the box body 1, an ash hopper 6 is fixedly connected to the lower side of the box body 1, a dust collecting bucket 7 is movably installed below the ash hopper 6, and a base 9 is abutted against the lower side of the dust collecting bucket 7. A supporting bracket is fixedly connected to the upper side of the base 9, and the upper side of the supporting bracket is fixedly connected to the box body 1. An electric box mounting plate 8 is fixedly connected to one side of the supporting bracket. By adopting the above technical solution, an electric box is installed on the outer side of the electric box mounting plate 8, which can control the electronic equipment on the dust collector;

[0031] A valve is installed at the lower end of the ash hopper 6. After the valve is opened, the dust in the ash hopper 6 falls into the dust collecting bucket 7 under the action of gravity.

[0032] like Figure 1-Figure 3 As shown, one side of the box body 1 is fixedly connected to a connecting air duct 3, the inner side of the connecting air duct 3 is fixedly installed with a thermistor sensor 13, one side of the connecting air duct 3 is fixedly connected to a fan 4, and the upper output end of the fan 4 is fixedly connected to a muffler 5. Through such an arrangement, the fan 4 draws the filtered air in the dust collector and discharges it when in use, and the muffler 5 can silence the noise of the fan 4 drawing air.

[0033] like Figure 1-Figure 2 As shown, two explosion-proof plates 10 are fixedly installed at equal distances on both sides of the box body 1. Through such an arrangement, a cloth bag made of a flame-resistant material with a dense mesh is installed on the outside of the explosion-proof plate 10. When an explosion occurs in the box body 1 and the pressure increases instantly, the explosion-proof plate 10 will explode under the action of the pressure to release the pressure, and the cloth bag can collect the fragments of the explosion-proof plate 10.

[0034] like Figure 1-Figure 3 As shown, connecting ball valves 11 are fixedly installed on both sides of the upper part of the connecting air duct 3, a pressure regulating valve 12 is fixedly connected to one side of the supporting bracket, the air outlets of the two connecting ball valves 11 are fixedly connected to hoses, and the two hoses are fixedly connected to the pressure regulating valve 12. A negative pressure differential gauge 25 is installed on the outside of the box body 1. Through such a setting, the pressure regulating valve 12 can automatically adjust the pressure on both sides of the pressure regulating valve 12.

[0035] like Figures 1-4As shown, a clean room sealing door 15 is fixedly installed on one side of the box body 1, a cooling nozzle 14 is fixedly installed on the upper side of the box body 1, and two slow flow plates 17 are fixedly connected to the inner side of the box body 1 at equal distances. The inner sides of the two slow flow plates 17 are fixedly connected to the partition 18. Through such an arrangement, the slow flow plate 17 is arranged above the filter cartridge 16, which can prevent the filter cartridge 16 from being damaged by impact when air enters the box body 1. At the same time, the top of the slow flow plate 17 is inclined, which can make the deposited dust slide down and prevent dust accumulation.

[0036] like Figure 1-Figure 5 As shown, an air bag tube 23 is fixedly installed on the outside of the partition 18, and six pulse valves 24 are fixedly installed on the outside of the air bag tube 23 at equal intervals. The nozzles of the six pulse valves 24 are aligned with the positions of the six venturi tubes 20 respectively. Through this arrangement, the air bag tube 23 can inflate the venturi tube 20 through the pulse valve 24, and the air flow back through the venturi tube 20 to remove the dust on the outer surface of the filter cartridge 16.

[0037] It should be noted that when in use, the base 9 is installed on a horizontal plane, the external power supply is connected through the electrical box, the fan 4 is started to extract the air in the box body 1, and the air that needs to be removed is injected through the air inlet 2. The air passes through the filter cartridge 16 in the box body 1 and enters the venturi 20, and then the air enters the connecting air duct 3 and is finally discharged through the muffler 5.

[0038] When the filtered dust needs to be collected, the air bag tube 23 is started, and air is inflated into the venturi tube 20 through the pulse valve 24. The air flow backflows through the venturi tube 20 to separate the dust on the outer surface of the filter cartridge 16. The separated dust falls into the ash hopper 6 under the action of gravity. The valve of the ash hopper 6 is opened, and the dust falls into the dust collecting barrel 7 for collection.

[0039] When the filter cartridge 16 needs to be replaced and repaired, the clean room sealing door 15 is opened and the fixing bolts 21 are removed. At this time, the filter cartridge cover 22 can be pulled outward. The filter cartridge cover 22 drives the skeleton pull rod 19 and the filter cartridge 16 to leave the box body 1 from the installation hole. At this time, the filter cartridge 16 can be repaired and replaced. At the same time, the filter cartridge 16 is installed obliquely in the box body 1 so that the air can more fully contact the filter cartridge 16.

[0040] When the temperature inside the box 1 is too high, the thermistor sensor 13 senses that the air temperature inside the box 1 is too high, and the dust collector automatically starts the cooling nozzle 14, which sprays water into the box 1 to cool the air and prevent dust from burning.

[0041] When the pressure in the box body 1 is too high, the pressure is transmitted to the side of the pressure regulating valve 12 through the connecting ball valve 11 and the hose through the air. The pressure regulating valve 12 adjusts the opening according to the air pressure to control the flow rate, so that the pressure in the box body 1 is maintained at a preset value.

[0042] The utility model provides an explosion-proof dust collector, which solves the problem that the filter cartridge of the existing explosion-proof dust collector is often installed vertically inside the dust collector, which is inconvenient to replace and repair. When the explosion-proof dust collector is removing dust, when a combustible mixture is formed inside the dust collector due to dust accumulation and other reasons and is ignited, the pressure inside the dust collector may be too high, causing the dust collector to rupture and damage. It is more practical.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
