Description

Technical Field

[0001] This utility model relates to the field of filter bag detection technology, specifically a filter bag detection device. Background Technology

[0002] Dust collector filter bags are key filtration elements used in baghouse dust collectors. They are mainly used to capture dust particles generated during industrial production processes to reduce air pollution, protect the environment, and improve working conditions. Dust collector filter bags are widely used in heavy industries such as steel, cement, power, chemical, and metallurgy. They are an important component of modern industrial dust removal technology. Their main principle is that the fibrous structure on the surface of the filter material blocks airborne particles and deposits them on the surface of the filter bag, thereby achieving the effect of air purification.

[0003] Filter bag inspection mainly includes the following aspects: visual inspection, checking for damage, wear, deformation, clumping, or chemical corrosion on the surface of the filter bag; dimensional measurement, ensuring that the size of the filter bag meets the design requirements to avoid installation problems or reduced filtration efficiency due to dimensional deviations; and filtration efficiency testing, testing the filtration efficiency of the filter bag to ensure that it can effectively capture dust particles.

[0004] Among the aforementioned testing aspects, filter bag filtration testing is the most important. Traditional filtration efficiency testing requires workers to place the filter bag on the air jet and then measure the dust concentration in the gas before and after filtration to calculate the filtration efficiency. However, this method not only requires manual operation but is also inefficient. Therefore, a more efficient testing device needs to be designed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a filter bag detection device to solve the technical problem of low efficiency in traditional detection methods.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filter bag detection device, comprising a main body, a conveyor belt installed inside the main body, a rotating motor installed inside the main body, first extension arms rotatably connected to both ends of the conveyor belt inside the main body, and limit wheels rotatably connected to the ends of the first extension arms, two output ends of the rotating motor being connected to the corresponding limit wheels through the first extension arms, one output end of the rotating motor being connected to a first rotating shaft, and a second extension arm being connected to the outer side of the first rotating shaft, the outer end of the second extension arm being connected to an air jet nozzle that cooperates with the limit wheel, an air jet device installed inside the main body, and an air pipe connected to the output end of the air jet device, the other end of the air pipe being connected to the air jet nozzle, and a dust detection device cooperating with the air jet nozzle being installed inside the main body.

[0007] By adopting the above technical solution, the conveyor belt feeds the filter bag into the interior of the main body. At this time, the first extension arm rotates downward so that the limiting wheel contacts the track. Then, the two limiting wheels rotate towards the middle, causing folds to form at the opening of the filter bag, thus creating an opening. Subsequently, the first rotating shaft rotates through the second extension arm so that the air jet nozzle extends into the interior of the filter bag through the opening. Then, the air jet device sprays dust-containing gas into the interior of the filter bag through the air pipe and the air jet nozzle. Then, the dust detection device detects the dust content in the air, thereby detecting the performance of the filter bag. After the detection is completed, the above steps are repeated in reverse to discharge the filter bag.

[0008] The present invention is further configured such that one of the output ends of the rotating motor is connected to a second rotating shaft, and a third extending arm is connected to the second rotating shaft, and the end of the third extending arm is connected to a locking block that cooperates with the jet nozzle.

[0009] By adopting the above technical solution, after the air jet is inserted into the filter bag, the second rotating shaft causes the locking block to rotate above the air jet via the third extension arm, thereby fixing the filter bag. Then the limiting wheel rotates in the opposite direction to tighten and close the bag opening of the filter bag, thereby preventing the filter bag from detaching from the air jet and preventing dust from leaking out of the filter bag opening.

[0010] The present invention is further configured such that an exhaust fan is installed inside the main body.

[0011] By adopting the above technical solution, after the test is completed, the exhaust fan is started to remove the dust from the main body to avoid affecting subsequent tests.

[0012] The present invention is further configured such that the conveyor belt is provided with a plurality of limiting grooves.

[0013] By adopting the above technical solution, the limiting groove is used to guide the track on the conveyor belt, prevent the filter bag from running off-center, and increase the friction between the conveyor belt and the filter bag.

[0014] In summary, the present invention has the following main advantages:

[0015] This invention uses a conveyor belt to feed the filter bag into the main body. At this time, two limiting wheels rotate towards the center, causing folds to form at the opening of the filter bag, thus creating an opening. Then, the first rotating shaft rotates and, through the second extending arm, allows the air jet nozzle to extend into the filter bag through the opening. Then, the air jet device sprays dust-containing gas into the filter bag through the air pipe and the air jet nozzle. Subsequently, the dust content in the air is detected by a dust detection device, thereby detecting the performance of the filter bag. This process requires manual assistance, saving manpower.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] A filter bag detection device, such as Figure 1-4 As shown, the device includes a main body 1, inside which a conveyor belt 2 is installed. A rotary motor is also installed inside the main body 1. First extension arms 3 are rotatably connected to both ends of the conveyor belt 2 inside the main body 1, and limit wheels 4 are rotatably connected to the ends of the first extension arms 3. Two output ends of the rotary motor are respectively connected to the corresponding limit wheels 4 via the first extension arms 3. One output end of the rotary motor is connected to a first rotating shaft 5, and a second extension arm 7 is connected to the outer side of the first rotating shaft 5. An air nozzle 9, which mates with the limit wheel 4, is connected to the outer end of the second extension arm 7. An air jet device is installed inside the main body 1, and the output end of the air jet device is connected to an air pipe 11. The other end of the air pipe 11 is connected to the air nozzle. The main body 1 is connected to the air nozzle 9. A dust detection device 12 that works with the air nozzle 9 is installed inside the main body 1. The conveyor belt 2 sends the filter bag into the main body 1. At this time, the first extension arm 3 rotates downward so that the limiting wheel 4 contacts the track. At this time, the two limiting wheels 4 rotate towards the middle, causing the filter bag opening to fold, thus creating an opening. Then, the first rotating shaft 5 rotates through the second extension arm 7 so that the air nozzle 9 extends into the filter bag through the filter bag opening. Then, the air jet device sprays dust-containing gas into the filter bag through the air pipe 11 and the air nozzle 9. Then, the dust detection device 12 detects the dust content in the air, thereby detecting the performance of the filter bag. After the detection is completed, the above steps are repeated in reverse to discharge the filter bag.

[0024] One of the output ends of the rotating motor is connected to a second rotating shaft 6, and a third extension arm 8 is connected to the second rotating shaft 6. The end of the third extension arm 8 is connected to a locking block 10 that cooperates with the air jet 9. After the air jet 9 is inserted into the filter bag, the second rotating shaft 6 causes the locking block 10 to rotate above the air jet 9 through the third extension arm 8, thereby fixing the filter bag. Then the limit wheel 4 rotates in the opposite direction to tighten and close the bag opening of the filter bag, thereby preventing the filter bag from falling off the air jet 9 and preventing dust from leaking out of the opening of the filter bag.

[0025] An exhaust fan is installed inside the main body 1. After the test is completed, the exhaust fan is turned on to remove the dust from the main body 1 so as not to affect subsequent tests.

[0026] The conveyor belt 2 is provided with several limiting grooves 13. The limiting grooves 13 are used to guide the track on the conveyor belt 2, prevent the filter bag from running off-center and increase the friction between the conveyor belt 2 and the filter bag.

[0027] Working principle: The conveyor belt 2 feeds the filter bag into the body 1. The limiting groove 13 guides the track on the conveyor belt 2, preventing the filter bag from deviating and increasing the friction between the conveyor belt 2 and the filter bag. At this time, the first extension arm 3 rotates downward so that the limiting wheel 4 contacts the track. The two limiting wheels 4 then rotate towards the center, causing folds to form at the opening of the filter bag, thus creating an opening. Subsequently, the first rotating shaft 5 rotates through the second extension arm 7, causing the air nozzle 9 to extend into the filter bag through the opening. The second rotating shaft 6, through the third extension arm 8, causes the locking block 10 to rotate to... Above the air jet nozzle 9, the filter bag is fixed in place. Then, the limiting wheel 4 rotates in the opposite direction to tighten and close the bag opening, thereby preventing the filter bag from detaching from the air jet nozzle 9 and preventing dust from leaking out of the filter bag opening. Then, the air jet device sprays dust-containing gas into the filter bag through the air pipe 11 and the air jet nozzle 9. Then, the dust detection device 12 detects the dust content in the air, thereby detecting the performance of the filter bag. After the test is completed, the above steps are repeated in reverse to discharge the filter bag. Then, the exhaust fan is started to discharge the dust from the main body 1 to avoid affecting subsequent tests.
