Description

Technical Field

[0001] This invention relates to the field of quartz waste gas treatment technology, specifically to an environmentally friendly treatment device for treating waste gas from quartz production. Background Technology

[0002] Quartz stone, as we commonly refer to it, is a new type of artificial stone made of over 90% quartz crystals, resin, and other trace elements. It is produced by pressing large-format slabs under specific physical and chemical conditions using specialized machinery. Its main material is quartz, a mineral that easily liquefies when heated or under pressure. It is also a fairly common rock-forming mineral, found in all three major rock types. Because it crystallizes last in igneous rocks, it usually lacks complete crystal faces, mostly filling the spaces between other pre-crystallized rock-forming minerals. Natural quartz crystals are typical refractory materials with a melting point exceeding 1300 degrees Celsius. Quartz stone, made from 94% natural quartz, is completely flame-retardant and will not burn upon contact with high temperatures. It also possesses high-temperature resistance properties unmatched by artificial stone countertops. Industrial processing of quartz stone involves multiple steps, including crushing, chemical reactions, and combustion, generating a large amount of quartz waste gas during these processes.

[0003] Quartz exhaust gas is treated by filtering it with filter media in daily operations. Ordinary pipes are vertical, with short filtration strokes and poor filtration effect. Moreover, the filter media needs to be replaced after a long period of filtration. However, to determine whether the filter media needs to be replaced, emissions need to be stopped and the filter media needs to be disassembled and inspected, which will affect the normal operation efficiency. There is a lack of a device for real-time monitoring of the filtration effect of the filter media. Summary of the Invention

[0004] The problem this invention aims to solve is that the filtration effect of the internal filter components of quartz stone exhaust gas is not ideal when it is discharged through the pipeline, and the filter material is overused and cannot be monitored in real time.

A plug-in shell is provided on the bottom of one side of the locking block. The front of the horizontal tube is provided with an outer shell.

[0012] Preferably, the control structure includes a water tank, a toothed plate, a connecting rod, a rotating handle, a fan, a protective plate, a bracket, and gears. A protective plate is provided at the bottom of one side of the main pipe, and a toothed plate extends through one side of the protective plate. A cavity is opened inside the toothed plate, and a water tank is provided on one side of the top of the toothed plate. A water leakage hole is provided at the bottom of the water tank.

The auxiliary wheel is adapted to the connecting rope. The other side of the connecting rope passes through the main pipe and the movable door in sequence and extends to the outside of the movable door. A pull ring is provided on one side of the connecting rope.

[0016] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0017] (1) The U-shaped pipe composed of the main pipe, secondary pipe and horizontal pipe increases the travel distance when exhausting the exhaust gas compared to the straight pipe. The increased travel distance allows for more filtration processes and more thorough exhaust gas treatment. The horizontal pipe and secondary pipe are equipped with a filtration structure and a monitoring structure. The filtration structure can be used in conjunction with the monitoring structure. The filtration structure uses three different filter media to efficiently filter the exhaust gas. The filter media can also be disassembled by the cooperation between the clip and the clip rod. When the filter media has been used for a long time and the filtration effect is poor, it can be quickly replaced. When the filter media has been used for a long time, the filtration effect inside will deteriorate. At this time, the filtration effect of the filter media can be monitored in real time by the adsorption block on the monitoring structure. When in use, some impurities in the exhaust gas will adhere to the adsorption block. When the impurities on the adsorption block reach a certain level, it will make the weight heavier. When the adsorption block becomes heavier, it means that it has been used for a period of time. As time goes on, more and more impurities accumulate. When it reaches a certain weight, it will control a series of linkages to make the alarm sound to remind the staff that the filter media needs to be replaced.

[0018] (2) The main pipe is equipped with a control structure. The control structure can complete two controls through the toothed plate. First, it can perform dust suppression treatment when the exhaust gas enters the pipe. The toothed plate has a cavity inside, which is connected to the water tank and the fan. After the water droplets in the water tank leak into the cavity, they will be blown into the main pipe by the strong wind of the fan to form water mist for dust suppression. Second, the toothed plate can also be controlled to move left and right by rotating gears. The exhaust gas emission can be controlled according to the actual use needs. The larger the distance it moves, the smaller the opening and the less exhaust gas is emitted. Conversely, the larger the distance, the greater the controllability of the device. It can be freely adjusted as needed. The connecting rod is equipped with a rotating handle to save effort and make it more convenient for the user to shake.

[0019] (3) A baffle tube is also installed inside the main pipe. The baffle tube can effectively block the dust in the exhaust gas. Since the baffle tube needs to be placed in the pipe for a long time, it also needs to be cleaned or replaced after a long period of use. Ordinary baffle tubes require the user to reach into the pipe to pick them up, which is very inconvenient to work inside the pipe. In this invention, a movable door is used in conjunction with a connecting rope to control its movement. When the user opens the movable door, the baffle tube can be pulled down along the pipe by the connecting rope until it is completely loosened and taken out for replacement or cleaning.

[0045] A fan 705 is provided on one side of the toothed plate 702, a bracket 707 is provided at the bottom of one side of the main pipe 5, a gear 708 is provided on one side of the bracket 707, the gear 708 meshes with the toothed plate 702, a connecting rod 703 is provided on the front of the gear 708, and a rotating handle 704 is provided at the bottom of the front of the connecting rod 703.

[0046] One side of the main pipe 5 is connected to a movable door 6 via a hinge. Inside the main pipe 5 is a barrier cylinder 9, inside the barrier cylinder 9 is a partition net 10. Limiting springs 11 are provided on both sides of the top and bottom of the barrier cylinder 9, and a top plate 8 is provided on one side of the limiting spring 11.

[0047] The top plate 8 is used to fix the barrier cylinder 9 inside the main pipe 5. A connecting rope 12 is provided on one side of the bottom of the barrier cylinder 9. An auxiliary wheel 14 is provided at the bottom of one side of the inner wall of the main pipe 5. The auxiliary wheel 14 is adapted to the connecting rope 12. The other side of the connecting rope 12 passes through the main pipe 5 and the movable door 6 in sequence and extends to the outside of the movable door 6. A pull ring 13 is provided on one side of the connecting rope 12.

[0048] The working principle and usage process of this invention: When using the device, the user needs to open the movable door 6 and place the barrier cylinder 9 into the main pipe 5. Simply push it upwards during placement; the top plate 8 on the barrier cylinder 9 will fix it inside the main pipe 5. After placement, close the movable door 6 to allow the quartz exhaust gas to be discharged from the bottom of the main pipe 5. The exhaust gas will pass through the main pipe 5, the horizontal pipe 4, and the secondary pipe 1 before being discharged. As the exhaust gas passes through the main pipe 5, it will pass through the barrier cylinder 9, where dust will be intercepted. Before interception, the user can also turn on the fan 705. The fan 705, in conjunction with the water dripping from the water tank 701, will discharge water mist from the cavity inside the toothed plate 702. The discharged water mist can further clean the dust in the exhaust gas. The system performs initial dust suppression and also controls the amount of exhaust gas discharged into the pipe. When the user needs to reduce the amount of exhaust gas discharged or shut down the pipe, they can hold the rotating handle 704 to rotate the connecting rod 703. The connecting rod 703 will drive the gear 708 to rotate. The gear 708, through its cooperation with the toothed plate 702, controls its movement to one side, thus controlling the size of the air inlet inside the pipe. After passing through the toothed plate 702 and the baffle cylinder 9, the exhaust gas will pass through the horizontal pipe 4. The horizontal pipe 4 is equipped with three different filter media 309 to further filter the exhaust gas and achieve the best filtration effect. Finally, the exhaust gas will be discharged outward through the secondary pipe 1. After long-term use, the baffle cylinder 9 and the filter media 309 will become visibly filtration-reduced. The effect gradually deteriorates, requiring replacement. This is because some impurities remain in the exhaust gas after the three-stage filtering process. These impurities are adsorbed onto the surface of the adsorption block 206. As more impurities are adsorbed, the block becomes heavier. This increased weight causes the adsorption block 206 to move downwards via the control line 205. The control line 205 then rotates the movable plate 209 around its connection point with the rotating shaft 208. This rotation compresses the return spring and, through the pull rope, disengages the barrier plate 211 from the contact head 210, connecting the battery compartment 202 to the contact head 210. Once connected, the alarm 201 connects to the battery compartment 202, triggering the alarm. After the alarm sounds, the user can... To replace or clean the filter media 309 and the barrier cylinder 9, when replacing the filter media 309, pull the push button. The push button will cause the insert block 306 to disengage from the insert housing 305. After disengagement, rotate the locking block 304 to disengage it from the locking rod 303. Then, hold the handle 301 to pull the filter media 309 upward from the horizontal tube 4. After pulling it out, choose to clean or replace it according to the actual situation. When the barrier cylinder 9 needs to be replaced, before opening the movable door 6, you can first close the main pipe 5 through the toothed plate 702, and then pull the pull ring 13. The pull ring 13 will pull the barrier cylinder 9 downward through the connecting rope 12. After pulling down the entire barrier cylinder 9, open the movable door 6 to take it out for cleaning or replacement.
