Description

Technical Field

[0001] The invention relates to the technical field of filter element detection, in particular to a filter element detection device for an air filter. Background Art

[0002] An air filter is a device that can filter particulate impurities in the air. The working principle of an air filter is to use filter media (such as filter paper) as the main filtering means. When air passes through the filter, the filter paper will block and absorb dust, sand and other impurities in the air, thereby purifying the air. This process can effectively prevent mechanical equipment from inhaling air with impurities during operation, which will aggravate the wear of parts.

[0003] To ensure the quality of air filters and improve product competitiveness, air filters are generally tested for their filtering capacity during production. However, when testing air filters, a single air filter can only test one type of air, while the types of pollution are different. Testing multiple pollution sources through multiple air filters not only lacks rigor in the experimental results, because performance differences between different filters, inconsistency in testing conditions and other factors may introduce errors, but this method also leads to a huge waste of resources, including filter materials, testing time, labor costs, etc. Summary of the invention

Cigarette smoke generators mainly produce solid particulate matter released when cigarettes burn; dry ice smoke generators actually produce tiny water droplets; liquid smoke generators produce tiny droplets formed by the evaporation and condensation of smoke oil; and electronic smoke generators produce aerosol particles formed by the evaporation of smoke oil.

When the conical tube 104 and the top of the inner cavity of the air filter body 5 are fitted, the conical tube 104 can be tightly fitted to the surface of the air filter body 5 under the action of the adjusting hose 105 and the first spring 103, thereby improving the sealing performance when the smoke suction tube 8 and the air filter body 5 are connected.

In this embodiment, through the arrangement of the engaging rod 121, the second spring 122 and the first fixed block 123, under the action of the first fixed block 123, the engaging rod 121 and the second spring 122 can be stably maintained at the specified position, thereby providing limitation and support for the operation of the transmission mechanism 11.

[0047] The transmission mechanism 11 includes a top block 111 fixed to one side of the surface of the driving block 7 and a threaded rod 114 sliding on the surface of the meshing rod 121.

The surface of the threaded rod 114 is meshed with a driving gear 115. Both sides of the surface of the driving gear 115 are slidably provided with a limit member 112. The other end of the limit member 112 is fixed to the surface of the support column 1. In this embodiment, by setting the top block 111, the limit member 112, the force head 113, the threaded rod 114 and the driving gear 115 When the driving block 7 drives the smoke suction tube 8 upward and enters the specified position, the top block 111 and the force-bearing head 113 can be fitted together, and then under the action of the force-bearing head 113, the threaded rod 114 is moved, and under the limit of the meshing rod 121, the threaded rod 114 and the driving gear 115 are meshed. Because the threaded rod 114 is in a restricted state, the driving gear 115 can be rotated under the action of the thread meshing force.

[0049] The thread lead angle of the threaded rod 114 is greater than the equivalent friction angle, so that the threaded rod 114 does not have self-locking properties, and then under the action of the second spring 122, the threaded rod 114 can move downward to achieve a reset effect.

[0050] The one-way mechanism 14 includes a plurality of placement blocks 141 fixed to the inner cavity of the driven gear 131, the surface of the placement block 141 is connected to an action sheet 142 through a spring shaft, the surface of the action sheet 142 is attached to a one-way wheel 143, the surface of the one-way wheel 143 is fixed to a fourth transmission rod 144, the other end of the fourth transmission rod 144 is provided with a rotating block 145 through transmission of the transmission rod, and the air filter body 5 is placed on the surface of the rotating block 145. In this embodiment, the placement block 141, the action sheet 142, the one-way wheel 143, the fourth transmission rod 144 and the rotating block 145 are connected to the one-way wheel 143. The setting of the moving block 145 is that when the driven gear 131 rotates, the multiple placement blocks 141 fixed to the inner cavity of the driven gear 131 can rotate, and then under the action of the spring shaft, the action piece 142 pushes the one-way wheel 143 to rotate, and the fourth transmission rod 144 fixed to the surface of the one-way wheel 143 can drive the rotating block 145 to rotate through the transmission shaft, and because the meshing between the action piece 142 and the one-way wheel 143 is unidirectional, the transmission between the driven gear 131 and the fourth transmission rod 144 is also unidirectional.

[0051] The driving mechanism 15 includes an action shell 151 fixed to one side of the surface of the driving block 7 and a first connecting air pipe 157 arranged in the inner cavity of the support column 1, the inner cavity of the action shell 151 is fixed with a second slide rod 152, the surface of the second slide rod 152 is slidably provided with a head 153, the second slide rod 152 limits the position of the head 153 by a spring, one end of the first connecting air pipe 157 is connected with a first piston tube 156, the inner cavity of the first piston tube 156 is slidably provided with a first piston head 155, the other end of the first piston head 155 is fixed with a driving head 154, the driving head 154 limits the position of the driving head 154 by a spring, in this embodiment, through the action shell 151, the second slide rod 152, the head 153, the driving head 154, the first piston head 155, the first piston tube The arrangement of 156 and the first connecting air pipe 157 allows the top head 153 and the driving head 154 to fit together after the driving block 7 drives the working shell 151 to enter the specified height, and under the action of the spring on the surface of the second slide rod 152, the driving head 154 first drives the first piston head 155 to move. At this time, the top head 153 is stationary relative to the working shell 151. After the driving head 154 fits on the surface of the first piston tube 156, the top head 153 can slide relative to the working shell 151. When the driving head 154 moves, the first piston head 155 can slide in the inner cavity of the first piston tube 156, thereby changing the air pressure in the inner cavity of the first piston tube 156, and under the action of the first connecting air pipe 157, the fixing mechanism 16 works.

[0052] The fixing mechanism 16 includes an action air pipe 161 connected to one end of the first connecting air pipe 157, one end of the action air pipe 161 is connected to the second connecting air pipe 162, the other end of the second connecting air pipe 162 is rotated and connected to the third connecting air pipe 163, the other end of the third connecting air pipe 163 is connected to a plurality of second piston tubes 164, the inner cavity of the second piston tube 164 is slidably provided with a second piston head 165, one side of the surface of the second piston head 165 is fixed with a push rod 166, the other end of the push rod 166 is fixed with a second fixing block 167, and the second piston tube 164 is provided with a second piston head 165. In the inner cavity of the rotating block 145, in this embodiment, through the setting of the working air pipe 161, the second connecting air pipe 162, the third connecting air pipe 163, the second piston tube 164, the second piston head 165, the push rod 166 and the second fixed block 167, after receiving the pressure change of the first connecting air pipe 157, the pressure in the inner cavity of the second piston tube 164 can be changed under the transmission of the working air pipe 161, the second connecting air pipe 162 and the third connecting air pipe 163, so that the second piston head 165 drives the push rod 166 and the second fixed block 167 to move.

[0053] The specifications of the second fixing block 167 are consistent with the specifications of the inner side of the air filter body 5. In this embodiment, through this arrangement, the surface of the second fixing block 167 is better fitted to the inner cavity of the air filter body 5, thereby improving the fixing ability of the fixing mechanism 16 to the air filter body 5.

[0054] The deflation mechanism 17 includes a through hole 171 fixed to the inner cavity of the working air pipe 161, a plurality of limiting rods 172 are fixed to the surface of the through hole 171, a blocking block 173 is slidably provided on the surface of the limiting rod 172, a return spring 174 is sleeved on the surface of the limiting rod 172, one end of the return spring 174 is fixed to the surface of the through hole 171, the other end of the return spring 174 is fixed to the surface of the blocking block 173, a pull rod 175 is fixed to one side of the surface of the blocking block 173, and a pulling head 176 is fixed to the other end of the pull rod 175. In this embodiment, the through hole 171, the limiting rod 172, the blocking block 173, the return spring 174 and the return spring 174 are sleeved on the surface of the limiting rod 172. 74. The arrangement of the pull rod 175 and the pulling head 176 is such that when the gas passes through the working air pipe 161, the gas can cause the block 173 to slide on the surface of the limiting rod 172. When no gas passes through the inner cavity of the first connecting air pipe 157, the block 173 can be pressed against the surface of the through hole 171 under the action of the reset spring 174, thereby achieving the one-way purpose. In addition, the staff can make the pulling head 176, and under the drive of the pulling head 176, the pull rod 175 pulls the block 173 to move, thereby releasing the gas in the inner cavity of the fixing mechanism 16, so that the staff can remove the air filter body 5 conveniently.

[0055] Working principle: When in use, the staff can place the air filter body 5 to be tested on the surface of the bottom circular shell 2, and make the rotating block 145 in the inner cavity of the air filter body 5, and then first use the electric push rod 6. Under the action of the electric push rod 6, the driving block 7 moves upward. We call the distance moved at this time one unit of upward movement.

[0056] When the driving block 7 moves upward one unit, the top head 153 and the driving head 154 are fitted together first, and then, driven by the top head 153, the driving head 154 drives the first piston head 155 to slide in the inner cavity of the first piston tube 156, and then, under the action of the first connecting air pipe 157, the fixing mechanism 16 works, and under the connection of the acting air pipe 161, the second connecting air pipe 162 and the third connecting air pipe 163, the second piston head 165 in the inner cavity of the second piston tube 164 moves, and then, driven by the push rod 166, the second fixing block 167 acts on the inner cavity of the air filter body 5, and then, under the action of the second fixing block 167, the air filter body 5 is fixed, so that one side of the surface of the air filter body 5 is tightly fitted to the surface of the smoke casing 3.

[0057] At this time, since the air filter body 5 is attached to the surface of the smoke casing 3 and the flue gas can only pass through the designated position of the air filter body 5 due to the grooves on the surface of the smoke casing 3, the staff can use the electric push rod 6 again. Driven by the electric push rod 6, the smoke suction tube 8 drives the connecting mechanism 10 to move, and under the action of the conical tube 104, the smoke suction tube 8 and the inner cavity of the air filter body 5 are attached, thereby achieving the purpose of connecting the smoke suction tube 8 and the air filter body 5.

[0058] Then the staff can use the smoke generator body 4. Under the action of the smoke generator body 4, the smoke fills the inner cavity of the smoke shell 3. Then the staff can use the gas treatment device 18. Under the action of the gas treatment device 18, negative pressure is generated in the smoke suction tube 8. Under the action of the negative pressure, the air inside the smoke shell 3 passes through the air filter body 5 and the smoke suction tube 8, and finally reaches the gas detector, so as to make a report on the experiment through the gas detector. The comparative data of the experiment comes from the smoke generator body 4.

[0059] After completing an experiment, the staff can change the type of smoke generated by the smoke generator body 4, and then use the electric push rod 6 again. Under the action of the electric push rod 6, the driving block 7 drives the smoke suction tube 8 to move upward to a specified position. Here we call this movement two units upward, so that the transmission mechanism 11 can work. When the threaded rod 114 moves upward, the driving gear 115 and the driven gear 131 can be engaged, and then under the action of the first transmission rod 132, the second transmission rod 133, the third transmission rod 134 and the rotating disk 135, the brush 136 cleans the inner cavity of the smoke suction tube 8 to avoid the residue of smoke particles. It is worth noting that when the brush 136 cleans the smoke suction tube 8, blowing should be generated in the gas treatment device 18 to improve the cleaning effect of the brush 136 on the smoke suction tube 8.

[0060] When the driving block 7 moves upward by two units, the action shell 151 , the second sliding rod 152 and the internal spring can buffer the working range of the action shell 151 .

[0061] When the transmission mechanism 11 drives the driven gear 131 to work, during the upward movement of the transmission mechanism 11, the driven gear 131 drives the one-way wheel 143 to rotate, and during the downward movement of the transmission mechanism 11, due to the meshing characteristics of the one-way wheel 143 and the action plate 142, the driven gear 131 does not drive the one-way wheel 143 to rotate.

[0062] When the one-way wheel 143 rotates, the fourth transmission rod 144 can drive the rotating block 145 to rotate. At this time, the air filter body 5 is fixed to the surface of the rotating block 145 by the second fixing block 167, so that the air filter body 5 can be rotated, and under the setting of the transmission ratio, the air filter body 5 can perform a half-circle motion, so that the non-working area of ​​the air filter body 5 is in contact with the surface of the smoke shell 3.

[0063] After the smoke suction pipe 8 is reset, the air filter body 5 can be tested again.
