Description

Technical Field

[0001] This utility model relates to the field of dehydrator technology, specifically to a dehydrator for a Venturi dust collector. Background Technology

[0002] With industrial development, the increase in pollutant emissions has caused significant damage to the atmospheric environment, making the control of air pollution an urgent matter. A dust collector is a device that separates dust from dust-laden gas. Depending on the cleaning method, dust collectors can be categorized as dry dust collectors, semi-dry dust collectors, and wet dust collectors. General dust collectors (such as inertial dust collectors and cyclone dust collectors) can separate dust particles (through a dehydration process), purifying the airflow. However, they have low efficiency in removing fine dust particles as small as 1µm, making it difficult to meet environmental requirements in situations with stringent regulations. Therefore, this paper proposes improvements to the structure of the dehydrator in existing Venturi dust collectors to enhance their dust removal efficiency.

[0003] To address the aforementioned technical problems, Chinese Patent No. CN206198914U discloses a novel dewatering device for a Venturi dust collector, comprising a dewatering device body, a primary separation chamber, a coalescing layer, a backwash pipe, and a drain outlet for the dewatering device body. The primary separation chamber is assembled at the bottom of the dewatering device body and connected to it. The coalescing layer is assembled inside the dewatering device body and uses a fiber coalescing filter element to remove fine droplets and dust from the gas. The backwash pipe is connected to the dewatering device body.

[0004] Although the aforementioned existing technical solutions have a long service life and can be used not only for dust removal but also for demisting, their coalescing layer is directly installed inside the dewatering unit. When particulate impurities accumulate and clog the inside of the filter holes and are difficult to flush out by water flow, or when the coalescing layer ages and breaks, it is impossible to quickly remove it from the inside of the dewatering unit for cleaning and maintenance or to replace it directly.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0023] A dewatering device for a Venturi dust collector includes a dewatering device body 1. A primary separation chamber 2 is installed at the bottom inner side of the dewatering device body 1. A tangential air inlet pipe 3 extending to the outside of the dewatering device body 1 is installed on one side of the primary separation chamber 2. A rectifier cylinder 4 is installed at the top of the primary separation chamber 2. Multiple sets of drain pipes 5 are embedded at the bottom of the primary separation chamber 2. A filter flushing mechanism is installed on the dewatering device body 1 near the top. The filter flushing mechanism includes a flushing component, a linkage component, a replacement component, and a filter layer 6. The flushing component is used to rinse and brush the filter layer 6. The drive component is used to drive the flushing component to brush and wipe, and the replacement component is used to disassemble and install the filter layer 6. When in use, the device can use the flushing component to rinse and brush the filter layer 6, the linkage component drives the flushing component to brush and wipe, and the replacement component disassembles and installs the filter layer 6. The structure is simple and easy to operate. It can perform double-sided auxiliary brushing when rinsing the filter layer 6, so that the accumulated particles can be more easily flushed away. It can also quickly disassemble and install the filter layer 6 to facilitate timely maintenance, cleaning or direct replacement of the aged and damaged filter layer 6.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the flushing assembly includes a water tank 7 installed at one end of the top of the dehydrator body 1. A water inlet hopper 8 is embedded in the top of the water tank 7. A top cover is attached to the top of the water inlet hopper 8 by a locking clip. An observation window is embedded in the outer wall of the water tank 7. A corrugated pipe 9 is embedded in one side of the water tank 7. A drain pipe 10 is installed at one end of the corrugated pipe 9 that extends into the interior of the dehydrator body 1. Multiple sets of electric spray nozzles 11 are arranged at the bottom of the drain pipe 10. First, after large particles in the airflow are separated by the primary separation chamber 2, the gas carrying small particles can continue to rise and pass through the filter layer 6 for filtration before being discharged. After a period of use, the electric spray nozzles 11 can be activated to spray the water source in the water tank 7 that flows into the drain pipe 10 through the corrugated pipe 9 outward onto the filter layer 6.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, two sets of adjusting grooves are arranged on the inner wall of the dehydrator body 1 near the top. A threaded rod 12 is rotatably connected to the inner side of each adjusting groove, and an adjusting block 13 is threadedly connected to the outer side of the threaded rod 12. A connecting plate 14 is installed on the other side of the adjusting block 13. A brush 15 is installed on the side of the connecting plate 14 near the filter layer 6. A dust cover 16 is installed on one side of the outer wall of the dehydrator body 1. Two sets of connecting rods are rotatably connected to the inner side of the dust cover 16. A sprocket 17 is installed at the other end of each connecting rod. The two sets of sprockets 17 are connected by a chain. A first motor 18 is installed on one side of the outer wall of the dust cover 16, and the drive end of the first motor 18 extends to the dust cover 1. The inner side of the 6 is fixedly connected to one end of one set of sprockets 17, and the other end of the connecting rod extends to the inner side of the adjustment groove and is fixedly connected to one end of the threaded rod 12. Then, the first motor 18 is started to drive one set of sprockets 17 to rotate. When this set of sprockets 17 rotates, it can drive the other set of sprockets 17 to rotate with the chain. The two sets of connecting rods will also rotate, causing the two sets of threaded rods 12 to rotate as well, so that the adjustment block 13 slides in the inner side of the adjustment groove. At the same time, the connecting plate 14 also drives the brush 15 to brush on both sides of the filter layer 6. When the drive end of the first motor 18 is reversed, the brush 15 can be driven to brush back again to achieve the effect of reciprocating brushing.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, the replacement component includes a groove on the other side of the outer wall of the dehydrator body 1. An arc-shaped plate 19 is slidably connected to the inside of the groove. One side of the arc-shaped plate 19 is fixedly connected to one side of the filter layer 6. A sealing ring is embedded at the contact point between the inner wall of the groove and the arc-shaped plate 19. An extension plate is installed on the other side of the outer wall of the arc-shaped plate 19. A rubber pad 20 is installed at the other end of the extension plate. A pull handle 21 is installed on the outer wall of the extension plate. A through hole is opened at one end of the rubber pad 20. A pressure plate 22 is installed on the outer wall of the extension plate at the through hole. A connecting platform 23 is installed on the other side of the outer wall of the dust cover 16. A pressure groove is opened on one side of the outer wall of the connecting platform 23, which is slidably connected to the pressure plate 22. A limiting groove is opened on both sides of the pressure groove inside the connecting platform 23. The side-sliding connection has a limiting plate 24. Furthermore, if the filtration effect is still not good after the filter layer 6 has been cleaned and brushed, the operator can hold the hanging ring 27 to drive the sliding rod 26 to slide inside the connecting groove. At the same time, the limiting plate 24 will retract towards the inside of the limiting groove and squeeze the two sets of limiting springs 25. After the protruding ends of the two sets of limiting plates 24 are dragged away from the two ends of the pressure plate 22, the pressure on the rubber pad 20 will disappear. The rubber pad 20 can drive the pressure plate 22 to move back and pop out part of the arc plate 19. At this time, the pressure plate 22 is away from the connection between the pressure groove and the limiting groove. Even if the hanging ring 27 is released, it will not lock again. At this time, holding the pull handle 21 can drive the extension plate, arc plate 19 and filter layer 6 to be pulled out for more detailed cleaning and maintenance.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the inner side of the limiting groove is connected to the inner side of the pressing groove. The opposing ends of the limiting plate 24 and the pressing plate 22 are provided with mutually fitting guide surfaces. Two sets of limiting springs 25 are arranged and installed between one side of the outer wall of the limiting plate 24 and the inner wall of the limiting groove. A sliding rod 26 is installed on the other side of the outer wall of the limiting plate 24. An operating groove is provided on one side of the outer wall of the connecting platform 23. A connecting groove extending to the inner side of the limiting groove is provided on the inner wall of the operating groove. The connecting groove and the sliding rod 26 are slidably connected. A hanging ring 27 is rotatably connected to one end of the sliding rod 26 extending to the inner side of the operating groove. Furthermore, after the filter layer 6 is maintained, it can be pushed back into the inner side of the dehydrator body 1. Partial entry of the pressing plate 22 into the pressing groove... Inside the groove, the extension plate and rubber pad 20 are then squeezed, forcing the rubber pad 20 to retract while the pressure plate 22 begins to move continuously into the groove. When the pressure plate 22 contacts the limiting plate 24, their guide surfaces abut against each other, forcing the limiting plate 24 to squeeze the two sets of limiting springs 25 and slide them into the groove. After the pressure plate 22 is fully pushed into the groove, the limiting springs 25 can drive the limiting plate 24 to pop out into the groove, so that the protruding end of the limiting plate 24 can press against the protruding end of the pressure plate 22, achieving the effect of locking the position of the filter layer 6 again. After locking, the sealing ring can fit against the outer wall of the arc plate 19, effectively increasing the sealing performance of the joint after installation and preventing gas leakage.

[0028] The implementation principle of a dewatering device for a Venturi dust collector according to an embodiment of this application is as follows: After large particles in the airflow are separated by the primary separation chamber 2, the gas carrying small particles can continue to rise, pass through the filter layer 6, and be discharged. After a period of use, the electric spray head 11 can be activated to spray the water source in the water storage tank 7, which flows into the drain pipe 10 through the corrugated pipe 9, onto the filter layer 6. Then, the first motor 18 is activated to drive one set of sprockets 17 to rotate. When this set of sprockets 17 rotates, it can drive the other set of sprockets 17 to rotate in conjunction with the chain. The two sets of connecting rods will also rotate accordingly, so that the two sets of screws... The treading rod 12 also rotates, causing the adjusting block 13 to slide inside the adjusting groove. At the same time, the connecting plate 14 drives the brush 15 to brush both sides of the filter layer 6. Reversing the drive end of the first motor 18 will drive the brush 15 to brush back again, achieving a reciprocating brushing effect. If the filtration effect of the filter layer 6 is still not good after cleaning and brushing, the operator can fasten the hanging ring 27 to drive the sliding rod 26 to slide inside the connecting groove. At the same time, the limiting plate 24 will retract towards the limiting groove and squeeze the two sets of limiting springs 25, dragging the protruding ends of the two sets of limiting plates 24 away from the pressure plate 2. After the ends of 2 are removed, the pressure on the rubber pad 20 disappears, and the rubber pad 20 can drive the pressure plate 22 to move back, causing the arc plate 19 to pop out part of itself. At this time, the pressure plate 22 is away from the connection between the pressure groove and the limiting groove, and it will not lock again even if the hanging ring 27 is released. At this time, holding the pull handle 21 can drive the extension plate, the arc plate 19 and the filter layer 6 to be pulled out for more detailed cleaning and maintenance. After the filter layer 6 is maintained, it can be put back into the inside of the dehydrator body 1. Part of the pressure plate 22 enters the inside of the pressure groove, and then the extension plate and the rubber pad 20 are squeezed, forcing the rubber pad 20 to... As the pressure plate 22 retracts, it begins to move continuously toward the inside of the pressure groove. When the pressure plate 22 contacts the limiting plate 24, their guide surfaces abut against each other, forcing the limiting plate 24 to squeeze the two sets of limiting springs 25 and slide toward the inside of the limiting groove. After the pressure plate 22 is fully pushed into the inside of the pressure groove, the limiting springs 25 can drive the limiting plate 24 to pop out to the inside of the pressure groove, so that the protruding end of the limiting plate 24 can press against the protruding end of the pressure plate 22, achieving the effect of locking the position of the filter layer 6 again. After locking, the sealing ring can fit against the outer wall of the arc plate 19, effectively increasing the sealing performance of the joint after installation and preventing gas leakage.

[0029] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
