Description

Technical Field

[0001] The invention relates to the technical field of detection devices, in particular to detection equipment for producing environmentally friendly dust removal filter bags. Background Art

[0002] The filter bag is a key part of the operation of the bag filter. Usually, the cylindrical filter bag is hung vertically in the dust collector. After the dust filter bag is produced, it needs to be tested in many aspects to ensure its quality, including the test of its breaking strength; however, there are still some problems in the use of the existing strength testing device, as follows:

[0003] During the existing detection device's process of testing the tensile strength of the dust filter bag, the force applied to the dust filter bag becomes increasingly greater. When the applied force reaches a critical value and causes the dust filter bag to break, the dust filter bag and the fixing structure will instantly collapse. The structure used to fix the dust filter bag in the detection device will experience a relatively violent collision. Long-term use will greatly accelerate the damage of the structure and reduce its fixing effect on the dust filter bag, resulting in unsatisfactory use of the existing detection device.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are only examples. The environmentally friendly dust filter bag production detection equipment involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0033] See also Figure 1-3 , a detection device for environmental protection dust filter bag production, comprising a bottom plate 1, a vertical wall 2 is fixedly installed on one side of the top of the bottom plate 1, a horizontal plate 3 is fixedly installed on the vertical wall 2, an outer frame 4 is movably installed on the horizontal plate 3, a support rod 5 is fixedly installed on the bottom end of the outer frame 4, a clamping assembly 6 is fixedly installed on the outer frame 4, a first hydraulic push rod 7 is fixedly installed in the outer frame 4, a locking assembly 8 is fixedly installed on the first hydraulic push rod 7, a vertical rod 9 is fixedly installed on the bottom plate 1, a secondary clamping head 10 is fixedly installed on the top of the vertical rod 9, a support member 11 is fixedly installed on the bottom plate 1, a second hydraulic push rod 12 is fixedly installed on the top of the support member 11, and a buffer assembly 13 is fixedly installed between the vertical wall 2 and the outer frame 4;

[0034] Compared with the prior art, the present application is provided with a locking assembly 8, and utilizes the inner block 82 to drive the pressing structure 83 to expand outward under the push of the first hydraulic push rod 7, thereby squeezing and fixing the dust filter bag wound and attached to the roller body 81. At the same time, combined with the vacuum effect of the buffer assembly 13, the connection of the inner tube 85 is utilized to form a negative pressure suction force between the end of the pressing structure 83 attached to the dust filter bag and the dust filter bag, thereby further ensuring the clamping stability of the dust filter bag, and in this way, no penetrating damage is caused to the dust filter bag, thereby ensuring the original strength of the dust filter bag, and thus ensuring the accuracy of the subsequent strength test results. At the same time, by installing a buffer assembly 13 between the outer frame 4 and the vertical wall 2, suction can be generated inside the locking assembly 8 through the air pump 131, and the gas will be discharged into the corrugated buffer hose 133 through the first air guide pipe 132. Under normal conditions The gas will maintain a relatively stable air pressure inside the corrugated buffer hose 133, and the excess gas will be discharged from one end of the corrugated buffer hose 133, thereby forming a buffering and non-rebound structure at one end of the outer frame 4. In this way, when the dust filter bag breaks during the strength test, the presence of the corrugated buffer hose 133 can not only form a buffering support for the outer frame 4, but also prevent the outer frame 4 from carrying the dust filter bag to collide violently back and forth, thereby ensuring the service life of the entire device. At the same time, the huge impact force generated at the time of breakage will guide the gas inside the corrugated buffer hose 133 from another outlet thereof through the exhaust pipe 134 into the airbag 63, thereby causing the airbag 63 to expand rapidly. The expanded airbag 63 will quickly clamp the dust filter bag to avoid violent rebound after the dust filter bag breaks, thereby protecting the service life of the device.

[0036] In this embodiment, it should be noted that when the dust filter bag is subjected to strength testing, the positioning rod on the outer frame 4 is moved in the horizontal groove on the horizontal plate 3 to ensure that the moving direction of the outer frame 4 is constant, thereby ensuring the accuracy of the dust filter bag strength test results.

[0037] See also Figure 1-3 , an environmentally friendly dust filter bag production detection equipment, including a bottom plate 1, bottom grooves are respectively opened at both ends of the upper surface of the bottom plate 1, a straight plate and a roller are arranged at the bottom end of a support rod 5, and the straight plate is arranged in the bottom groove, and the telescopic end of a second hydraulic push rod 12 is fixedly installed on an outer frame 4;

[0038] In this embodiment, it should be noted that under the telescopic action of the second hydraulic push rod 12, the support rod 5 can be used to ensure the overall stable movement of the outer frame 4. Combined with the positioning rod on the side of the outer frame 4, it can further ensure that the structure of this part can effectively fix the dust filter bag and perform subsequent inspections, thereby ensuring the accuracy of the inspection results.

[0039] See also Figure 2-3 , a detection device for environmentally friendly dust filter bag production, including a clamping assembly 6, the clamping assembly 6 includes a supporting short rod 61, a clamping block 62 is fixedly installed on the top of the supporting short rod 61, and an air bag 63 is fixedly installed inside the clamping block 62;

[0040] In the present embodiment, it should be noted that the clamping block 62 is U-shaped and is arranged on the side of the dust filter bag, the airbag 63 is connected through the buffer assembly 13, and an infrared rangefinder is fixedly installed on the support short rod 61 on the side where the auxiliary clamping head 10 is located. In this way, when the dust filter bag breaks, the airbag 63 can be quickly inflated with the help of the buffer assembly 13, so that it can expand quickly and then clamp the dust filter bag to ensure that the dust filter bag will not break and swing excessively at the moment of breaking, thereby avoiding damage to the device by the dust filter bag. At the same time, the infrared rangefinder can also be used to record the stretching distance and tensile strength during the strength test, so that the test result is more comprehensive and accurate; and a sensor is provided on the clamping block 62 for detecting the force applied at the moment of the dust filter bag breaking.

[0041] See also Figure 3-8 , a detection device for environmentally friendly dust filter bag production, including a locking assembly 8, the locking assembly 8 includes a roller body 81, an inner block 82 is movably installed inside the roller body 81, a pressing structure 83 is embedded and movably installed on the roller body 81, a pressing plate 84 is fixedly installed outside the roller body 81, an inner tube 85 is fixedly installed inside the roller body 81, an air guide port 86 is opened in the roller body 81, and a limiting guide rod 87 is fixedly installed inside the roller body 81;

[0042] In this embodiment, it should be noted that the roller body 81 is an annular structure and an annular groove is provided in the middle of the outer surface. A dust filter bag is provided in the annular groove of the roller body 81. One end of the inner block 82 is fixedly connected to the telescopic end of the first hydraulic push rod 7. The limiting guide rod 87 is fixedly installed in the inner ring of the roller body 81. One end of the pressing structure 83 located inside the roller body 81 is movably arranged with the inner block 82. The number of the pressing structure 83 and the pressing plate 84 are both two and they are arranged in pairs at 90 degrees on the roller body 81. The inner tube 85 is The two ends are respectively sealed and fixedly connected to the pressing structure 83, and the air guide port 86 passes through the inner tube 85 and is sealed therewith, so that the extension and contraction of the first hydraulic push rod 7 can drive the inner block 82 to move in the roller body 81, and the movement of the inner block 82 will cause the pressing structure 83 to expand outward, thereby driving the dust filter bag to press against the bottom surface of the pressing plate 84, thereby clamping the dust filter bag. Such a clamping method can ensure that the dust filter bag itself is not damaged, thereby ensuring the accuracy of the test results during the tensile strength test.

[0043] See also Figure 8-9 , a detection device for environmentally friendly dust filter bag production, including an inner block 82, the inner block 82 includes a base roller 821, a straight groove 822 is provided on the base roller 821, and a limiting groove 823 is evenly provided on the base roller 821 in a circumferential direction, and an inclined block 824 is fixedly installed in the straight groove 822, the number of the straight groove 822 is two and they are arranged at 90 degrees corresponding to the positions of the two pressure plates 84, the limiting groove 823 is movably inserted on the limiting guide rod 87, and the inclined block 824 is arranged on the side where the bottom of the pressure structure 83 is located;

[0044] In this embodiment, it should be noted that when the first hydraulic push rod 7 starts to push the base roller 821 to move, it will drive the inclined block 824 to move to the bottom end of the pressing structure 83, and then extend the pressing structure 83 outward from the roller body 81, and then push the dust filter bag attached to the annular groove of the roller body 81 toward the pressing plate 84 for pressing and clamping. In this way, the dust filter bag can be fixed without being damaged while ensuring the fixing effect of the dust filter bag, thereby ensuring the accuracy of the subsequent dust filter bag strength test results.

[0045] See also Figure 7-9 , a detection device for environmentally friendly dust filter bag production, including a pressing structure 83, the pressing structure 83 includes a central rod 831, a resisting block 832 is fixedly installed on the top of the central rod 831, a spring 833 is movably sleeved and installed on the central rod 831, a ventilation groove is provided in the central rod 831, a first notch 834 is provided on one side of the central rod 831, a second notch 835 is provided on the resisting block 832, a slope structure adapted to the inclined block 824 is provided at the bottom end of the central rod 831, the spring 833 is arranged to fit the outer surface of the roller body 81, the first notch 834 and the second notch 835 penetrate the ventilation groove inside the central rod 831, and the first notch 834 penetrates the inner tube 85;

[0046] In this embodiment, it should be noted that the movement of the inner block 82 can cause the inclined block 824 to abut against the bottom of the center rod 831, and then the inclined surface can be used to make the abutment block 832 extend from the top, thereby pushing the dust filter bag to the bottom of the pressure plate 84. At the same time, the buffer assembly 13 will generate suction, so that the abutment block 832 is only adsorbed on the bottom surface of the dust filter bag, further improving the clamping and fixing effect of the dust filter bag.

[0047] See also Figure 1-4 , a detection device for environmentally friendly dust filter bag production, comprising a buffer assembly 13, the buffer assembly 13 comprises an air pump 131, both ends of the air pump 131 are respectively fixedly mounted with a first air guide pipe 132, the end of the first air guide pipe 132 is fixedly connected with a corrugated buffer hose 133, and the upper part of the corrugated buffer hose 133 is fixedly connected with an exhaust pipe 134;

[0048] In the present embodiment, it should be noted that the other end of the first air duct 132 is sealed and connected to the air duct port 86, the two ends of the corrugated buffer hose 133 are respectively fixedly connected to the vertical wall 2 and the outer frame 4, and one end of the exhaust pipe 134 is sealed and connected to the airbag 63. In this way, under the action of the pressure applied during the detection process, the corrugated buffer hose 133 is always in a relatively stable internal pressure, thereby ensuring that after the dust filter bag breaks, the outer frame 4 can be buffered as a whole under the action of the corrugated buffer hose 133, and because the corrugated buffer hose 133 is filled with gas and can be discharged, the corrugated buffer hose 133 can avoid excessive rebound during the buffering process of the outer frame 4, thereby ensuring a smooth buffering effect.

[0049] See also Figure 4-5 , a detection device for environmentally friendly dust filter bag production, including a corrugated buffer hose 133, the corrugated buffer hose 133 includes a tube body 1331, exhaust ports 1332 are respectively opened on both sides of the top of the tube body 1331, an air inlet 1333 is opened in the middle of one end of the tube body 1331, and an air valve 1334 is movably installed in the exhaust port 1332 at one end;

[0050] In the present embodiment, it should be noted that the exhaust port 1332 at one end of the air valve 1334 is sealed and connected with the exhaust pipe 134, and the air inlet 1333 is sealed and connected with the first air guide pipe 132. The air valve 1334 is provided with an opening pressure threshold, and the threshold is less than the maximum impact force threshold that can be generated at the moment of the dust filter bag breaking. In this way, when the dust filter bag is not broken, the air pump 131 is used to generate suction at the second notch 835, thereby improving the fixing effect of the dust filter bag through negative pressure adsorption, and the gas is discharged into the interior of the tube body 1331. Since the exhaust port 1332 at one end of the air valve 1334 is not provided, the air inlet 1333 is sealed and connected with the first air guide pipe 132. The air valve 1334 is provided with an opening pressure threshold, and the threshold is less than the maximum impact force threshold that can be generated at the moment of the dust filter bag breaking. In this way, when the dust filter bag is not broken, the air pump 131 is used to generate suction at the second notch 835, and then the fixing effect of the dust filter bag is improved through negative pressure adsorption, and the gas is discharged into the interior of the tube body 1331. The existence of 332 can continuously and slowly discharge the gas, so that a relatively stable air pressure is always maintained inside it, thereby preparing to buffer the instantaneous impact force caused by the dust filter bag breaking. When the dust filter bag breaks, the internal pressure of the tube body 1331 increases instantly due to the instantaneous high-pressure impact, and the exhaust port 1332 cannot release the pressure in time, so that the air valve 1334 can be opened, allowing the gas to enter the airbag 63, and then the airbag 63 can be quickly inflated. In this way, the broken dust filter bag can be clamped in time to avoid damage to the device caused by the broken dust filter bag, thereby greatly ensuring the service life of the device.

[0051] Working principle: one end of the dust filter bag is passed through the clamping assembly 6 and the auxiliary clamping head 10, and fits into the annular groove of the roller body 81, and then the first hydraulic push rod 7 is started. The first hydraulic push rod 7 drives the base roller 821 to move horizontally inside the roller body 81, so that the inclined block 824 squeezes the bottom of the spring 833, so that the second notch 835 expands outward from the roller body 81 to the bottom of the dust filter bag, until the dust filter bag is pressed against the bottom end of the pressure plate 84, and at the same time the air pump 131 is started, the air pump 131 will form a negative pressure adsorption effect at the second notch 835, and the other end will fill the gas into the tube body 1331, and the gas will slowly and continuously be discharged from the exhaust port 1332 at one end, so that a relatively stable pressure is maintained inside the tube body 1331, so that the dust filter bag is fixed;

[0052] Start the second hydraulic push rod 12, which will drive the outer frame 4 to move laterally, forming a pulling force on the dust filter bag, thereby realizing strength testing. Various data are recorded during the testing process until the moment the dust filter bag breaks, and the value of the force applied by the second hydraulic push rod 12 at this time is recorded. The outer frame 4 will also generate a very large pressure on the tube body 1331 when it breaks, thereby causing the internal pressure of the tube body 1331 to increase instantly, thereby causing the air valve 1334 to be opened, and the gas enters the airbag 63 through the exhaust pipe 134, causing the airbag 63 to inflate quickly and expand, thereby clamping the dust filter bag to prevent it from being swung significantly to damage the detection device.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
