Description

Technical Field

[0001] This invention relates to the field of gas treatment technology, specifically to a gas purification and treatment device for factory processing. Background Technology

[0002] Gas purification devices for factory processing are typically used to purify gases generated during processing in factories, with the aim of minimizing the direct emission of harmful gases that could pollute the environment.

[0003] Patent publication number CN217549471U relates to a hazardous gas treatment device for chemical plants, comprising a housing, a partition fixedly connected to the inner wall of the housing, an air inlet on the left side of the housing, an air outlet on the right side of the housing, a drain pipe connected to the bottom of the right side of the housing, and a disassembly port on the left side of the top of the housing. This patent, through the cooperation of the housing, partition, air inlet, air outlet, drain pipe, disassembly port, sealing cover, vertical plate, suction fan, ventilation pipe, connecting pipe, positioning plate, mounting block, filter element, connecting block, insertion rod, telescopic rod, push plate, and spring, realizes a hazardous gas treatment device for chemical plants. It avoids the conventional method of installing the sealing cover with bolts and nuts, allowing workers to easily remove the filter element and working mechanism from the housing with minimal time and effort. This facilitates filter element replacement and suction fan maintenance and repair, reducing the workload of workers.

[0004] The aforementioned patent achieves a relatively ideal effect through a simple structure, allowing the filter element to be easily removed from the device and replaced. However, if the device operates continuously for a long time, the inner wall of the device may accumulate dust due to the processing of dusty gas. If it is not cleaned in time, it may lead to a decrease in the processing quality during subsequent work. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a gas purification and treatment device for factory processing, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gas purification and treatment device for factory processing, comprising a treatment tank, an inlet pipe fixedly installed at the rear of the treatment tank, an exhaust pipe fixedly installed at the front of the treatment tank, a motor fixedly installed at the rear of the treatment tank, a filter plate fixedly installed inside the treatment tank, a spiral scraper slidably installed inside the treatment tank, a reciprocating screw fixedly connected to the output end of the motor, a threaded connection between the top of the spiral scraper and the reciprocating screw, a rotating connecting rod rotatably installed at the bottom of the spiral scraper, a filter plate scraper slidably installed on the inner wall of the treatment tank, and a section of the rotating connecting rod away from the spiral scraper. The end is rotatably connected to the rear of the filter plate scraper. Two one-way doors are rotatably installed at the bottom of the treatment tank. A trapezoidal top block is fixedly installed on the top of each of the two one-way doors. A dust box is fixedly installed at the bottom of the treatment tank. The reciprocating screw drives the circular scraper and the filter plate scraper to move, thereby scraping off the accumulated dust on the inner wall of the device and the surface of the filter plate. This prevents the surface from accumulating dust over a long period of time, which would affect the processing quality in subsequent processes. At the same time, the sliding of the circular scraper drives the one-way door to rotate through the trapezoidal top block, thereby indirectly opening the ash discharge port and collecting the scraped dust into the dust box, preventing dust from being generated inside the device when air enters through the air inlet pipe.

[0007] According to the above technical solution, the front part of the filter plate scraper contacts the rear part of the filter plate, the bottom of the treatment tank is provided with a ash discharge port, the trapezoidal top block is located on the movement trajectory of the spiral scraper, and a spiral spring is provided between the one-way door and the treatment tank. The one-way door rotates downwards in one direction to avoid the ash discharge port being open for a long time, thereby causing dust to rise inside the device.

[0008] According to the above technical solution, two inner partitions are fixedly installed inside the treatment tank, and an activated carbon plate is slidably installed between the two inner partitions. A replacement handle is fixedly installed on the top of the activated carbon plate. A small gear is fixedly installed on the circumferential surface of the front end of the reciprocating screw. A rotating wheel is rotatably installed on the top of the inner wall of the treatment tank, and a small gear is fixedly installed on the bottom of the rotating wheel. A limit buckle is slidably installed on the top of the inner wall of the treatment tank. An anti-pull groove is provided at the rear of the replacement handle. The replacement of the activated carbon plate is realized through the replacement handle. The rotation of the reciprocating screw drives the limit buckle to contact the anti-pull groove through the small gear and the rotating wheel, thereby forming a limit. That is, when the device is in operation, the activated carbon plate cannot be replaced, avoiding danger caused by operator error.

[0009] According to the above technical solution, a rotating base is slidably installed between the two inner partitions, a rotating partition is rotatably installed at the bottom of the rotating base, a telescopic partition is rotatably installed at the front of the rotating base, and a sliding base is slidably installed at the bottom of the inner wall of the treatment tank. The ends of the rotating partition and the telescopic partition away from the rotating base are rotatably connected to the sliding base. The rotating partition and the telescopic partition are used to form an isolation inside the treatment tank during the replacement of the activated carbon plate to prevent gas leakage when the device is replaced after it has stopped working.

[0010] According to the above technical solution, the first pinion meshes with the second pinion, the limiting buckle is located on the movement trajectory of the rotating dial, the anti-pull groove is located on the movement trajectory of the limiting buckle, a return spring is provided between the rotating base and the inner partition, and a return spring is provided between the limiting buckle and the processing tank. The return spring is used so that when the device stops working, the limiting buckle can return to its initial position under its rebound force, thereby releasing the limitation between the limiting buckle and the anti-pull groove.

[0011] According to the above technical solution, an auxiliary ash discharge device is provided inside the treatment tank. The auxiliary ash discharge device includes a door opening lever and a sliding door. The door opening lever is rotatably installed at the bottom of the inner wall of the treatment tank. A telescopic connecting rod is rotatably installed at the rear of the door opening lever. The sliding door is slidably installed at the front of the dust box. The rear of the telescopic connecting rod is rotatably connected to the front of the sliding door. The door opening lever and the sliding door are moved by the process of replacing the activated carbon plate, so that the sliding door automatically opens when the operator replaces the activated carbon plate, thereby discharging the dust collected in the dust box.

[0012] According to the above technical solution, the auxiliary ash removal device further includes a rack, a large gear, a large gear, a rack, and a U-shaped scraper. The rack is fixedly installed on the side of the sliding base. The large gear is rotatably installed on the bottom of the inner wall of the treatment tank. The large gear is rotatably installed on the bottom of the treatment tank. The large gear is fixedly connected to the large gear through a gear shaft. The rack is slidably installed on the bottom of the treatment tank. The U-shaped scraper is fixedly installed on the rear of the rack. The movement of the sliding base drives the U-shaped scraper to slide through the gears and rack, thereby scraping off the dust adhering to the inner wall of the dust box. This prevents dust from accumulating inside the dust box after the device has been working for a long time, which could cause the dust to flow back into the device.

[0013] According to the above technical solution, a spiral spring is provided between the door opening lever and the treatment tank. The top of the door opening lever contacts the bottom of the rotating base. The rack is engaged with the large gear, and the large gear is engaged with the rack. The U-shaped scraper is in contact with the inner wall of the dust box. A telescopic scraper is slidably installed at the bottom of the U-shaped scraper. The bottom of the telescopic scraper contacts the top of the inner wall of the dust box. A return spring is provided between the telescopic scraper and the U-shaped scraper. Since the bottom of the dust box is inclined, the telescopic scraper is used to expand the scraping range of the U-shaped scraper on the inner wall of the dust box, thereby maximizing the scraping efficiency.

[0014] This invention provides a gas purification and treatment device for factory processing. It has the following beneficial effects:

[0015] (1) This invention uses a reciprocating screw to drive the circular scraper and the filter plate scraper to move, thereby scraping off the dust accumulated on the inner wall of the device and the surface of the filter plate. This avoids dust accumulation on the surface due to long-term operation, which would affect the processing quality in subsequent processes. At the same time, the sliding of the circular scraper drives the one-way door to rotate through the trapezoidal top block, thereby indirectly opening the ash discharge port and collecting the scraped dust into the dust box, thus avoiding dust generation inside the device when the air intake pipe is inlet.

[0016] (2) This invention realizes the replacement operation of activated carbon plate by changing the handle. The rotation of the reciprocating screw drives the limit buckle to contact the anti-pull groove through the pinion 1, pinion 2 and rotating dial to form a limit, that is, the activated carbon plate cannot be replaced when the device is in operation, avoiding the danger caused by the operator replacing the activated carbon plate during the operation of the device. At the same time, when replacing the activated carbon plate, the rotating base and sliding base drive the rotating partition and telescopic partition to move, realizing that the two partitions form a partition inside the device during the replacement of the activated carbon plate, minimizing gas leakage when replacing the activated carbon plate.

[0017] (3) In this invention, the process of replacing the activated carbon plate drives the door opening lever and the sliding door to move, so that the sliding door opens automatically when the operator replaces the activated carbon plate, thereby discharging the dust collected in the dust box. At the same time, the movement of the sliding base drives the U-shaped scraper to slide through the gear rack, thereby scraping off the dust attached to the inner wall of the dust box, thus avoiding the accumulation of dust inside the dust box after the device has been working for a long time, which may cause the dust to flow back into the device.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-7A gas purification device for factory processing includes a treatment tank 1, an inlet pipe 2 fixedly installed at the rear of the treatment tank 1, an exhaust pipe 3 fixedly installed at the front of the treatment tank 1, a motor 4 fixedly installed at the rear of the treatment tank 1, a filter plate 5 fixedly installed inside the treatment tank 1, a spiral scraper 801 slidably installed inside the treatment tank 1, a reciprocating screw 802 fixedly connected to the output end of the motor 4, a threaded connection between the top of the spiral scraper 801 and the reciprocating screw 802, a rotating connecting rod 803 rotatably installed at the bottom of the spiral scraper 801, a filter plate scraper 804 slidably installed on the inner wall of the treatment tank 1, and a rotatably connected end of the rotating connecting rod 803 away from the spiral scraper 801 to the rear of the filter plate scraper 804. Two one-way doors 805 are rotatably installed at the bottom of the treatment tank 1. Each one-way door 805 has a trapezoidal top block 806 fixedly installed on its top. A dust box 807 is fixedly installed at the bottom of the treatment tank 1. The reciprocating screw 802 drives the circular scraper 801 and the filter plate scraper 804 to move, thereby scraping off the dust accumulated on the inner wall of the device and the surface of the filter plate 5. This prevents the surface from accumulating dust over a long period of time, which would affect the processing quality in subsequent processes. At the same time, the sliding of the circular scraper 801 drives the one-way door 805 to rotate through the trapezoidal top block 806, thereby indirectly opening the ash discharge port and collecting the scraped dust into the dust box 807, preventing dust from being generated inside the device when the air inlet pipe 2 is inlet.

[0028] The front part of the filter plate scraper 804 contacts the rear part of the filter plate 5. The bottom of the treatment tank 1 is provided with a ash discharge port. The trapezoidal top block 806 is located on the movement trajectory of the spiral scraper 801. A spiral spring is provided between the one-way door 805 and the treatment tank 1. The one-way door 805 rotates downwards in one direction to avoid the ash discharge port from being open for a long time, thereby causing dust to rise inside the device.

[0029] The treatment tank 1 has two internal partitions 6 fixedly installed inside, and an activated carbon plate 7 is slidably installed between the two internal partitions 6. A replacement handle 10 is fixedly installed on the top of the activated carbon plate 7. A small gear 901 is fixedly installed on the circumferential surface of the front end of the reciprocating screw 802. A rotating wheel 902 is rotatably installed on the top of the inner wall of the treatment tank 1. A small gear 903 is fixedly installed on the bottom of the rotating wheel 902. A limit buckle 904 is slidably installed on the top of the inner wall of the treatment tank 1. An anti-pull groove is opened at the rear of the replacement handle 10. The replacement operation of the activated carbon plate 7 is realized by the replacement handle 10. The rotation of the reciprocating screw 802 drives the limit buckle 904 to contact the anti-pull groove through the small gear 901, the small gear 903 and the rotating wheel 902, thereby forming a limit. That is, when the device is in operation, the activated carbon plate 7 cannot be replaced, avoiding the danger caused by operator error.

[0030] A rotating base 905 is slidably installed between two inner partitions 6. A rotating partition 906 is slidably installed at the bottom of the rotating base 905. A telescopic partition 907 is slidably installed at the front of the rotating base 905. A sliding base 908 is slidably installed at the bottom of the inner wall of the treatment tank 1. The ends of the rotating partition 906 and the telescopic partition 907 away from the rotating base 905 are slidably connected to the sliding base 908. The rotating partition 906 and the telescopic partition 907 are used to form an isolation inside the treatment tank 1 during the replacement of the activated carbon plate 7 to prevent gas leakage when the device is replaced after it has stopped working.

[0031] Pinion 1 901 meshes with pinion 2 903. Limiting buckle 904 is located on the movement trajectory of rotating dial 902. Anti-pull groove is located on the movement trajectory of limiting buckle 904. A return spring 1 is provided between rotating base 905 and inner partition 6. A return spring 2 is provided between limiting buckle 904 and processing tank 1. The return spring 2 is used to allow limiting buckle 904 to return to its initial position under its rebound force when the device stops working, thereby releasing the limitation between limiting buckle 904 and anti-pull groove.

[0032] The treatment tank 1 is equipped with an auxiliary ash discharge device, which includes a door opening lever 1101 and a sliding door 1102. The door opening lever 1101 is rotatably installed on the bottom of the inner wall of the treatment tank 1. A telescopic connecting rod is rotatably installed at the rear of the door opening lever 1101. The sliding door 1102 is slidably installed at the front of the dust box 807. The rear of the telescopic connecting rod is rotatably connected to the front of the sliding door 1102. The door opening lever 1101 and the sliding door 1102 are moved by the process of replacing the activated carbon plate 7, so that the sliding door 1102 automatically opens when the operator replaces the activated carbon plate 7, thereby discharging the dust collected in the dust box 807.

[0033] The auxiliary ash removal device also includes rack 1103, large gear 1104, large gear 2 1105, rack 2 1106, and U-shaped scraper 1107. Rack 1103 is fixedly installed on the side of sliding base 908. Large gear 1104 is rotatably installed on the bottom of the inner wall of treatment tank 1. Large gear 2 1105 is rotatably installed on the bottom of treatment tank 1. Large gear 1104 and large gear 2 1105 are fixedly connected by a gear shaft. Rack 2 1106 is slidably installed on the bottom of treatment tank 1. U-shaped scraper 1107 is fixedly installed on the rear of rack 2 1106. The movement of sliding base 908 drives U-shaped scraper 1107 to slide through the gear rack, thereby scraping off the dust adhering to the inner wall of dust box 807. This prevents dust from accumulating inside dust box 807 after long-term operation, which could cause dust to flow back into the device.

[0034] A spiral spring is installed between the door opening lever 1101 and the treatment tank 1. The top of the door opening lever 1101 contacts the bottom of the rotating base 905. The rack 1103 meshes with the large gear 1104, and the large gear 2105 meshes with the rack 221106. The U-shaped scraper 1107 contacts the inner wall of the dust box 807. A telescopic scraper is slidably installed at the bottom of the U-shaped scraper 1107. The bottom of the telescopic scraper contacts the top of the inner wall of the dust box 807. A return spring is installed between the telescopic scraper and the U-shaped scraper 1107. Since the bottom of the dust box 807 is in an inclined state, the telescopic scraper is used to expand the scraping range of the U-shaped scraper 1107 on the inner wall of the dust box 807, thereby maximizing the scraping efficiency.

[0035] During operation: When the device enters the working state, the motor 4 is started first. The gas to be treated enters the processing tank 1 through the inlet pipe 2. After the motor 4 starts, it drives the reciprocating screw 802 to rotate. Since the reciprocating screw 802 is threadedly connected to the top of the spiral scraper 801, the rotation of the reciprocating screw 802 drives the spiral scraper 801 to slide back and forth, thereby scraping away the dust attached to the inner wall of the processing tank 1. When the spiral scraper 801 slides forward, it drives the rotating connecting rod 803 and its rotatably connected end to slide forward together. Since the end of the rotating connecting rod 803 away from the spiral scraper 801 is rotatably connected to the filter plate scraper 804 and the filter plate scraper 804 is slidably installed on the inner wall of the processing tank 1, the forward sliding of the spiral scraper 801 drives the end of the rotating connecting rod 803 away from the spiral scraper 801 and the filter plate scraper 804 to slide upward together, thereby scraping away the dust attached to the back of the filter plate 5. Meanwhile, during the sliding process, the bottom of the spiral scraper 801 contacts the trapezoidal top block 806, causing it to slide downwards. The sliding of the trapezoidal top block 806 causes the one-way door 805 to rotate downwards. After the one-way door 805 rotates, it opens the ash discharge port, thereby collecting the scraped dust into the dust box 807, preventing dust from accumulating inside the device and causing dust to be generated during operation.

[0036] The rotation of the reciprocating screw 802 drives the first pinion 901 to rotate, which in turn drives the second pinion 903 to rotate. The rotation of the second pinion 903 drives the rotating wheel 902 to rotate as well. During the rotation, the rotating wheel 902 will contact the limit buckle 904 due to centrifugal force and slide forward. After sliding forward, the limit buckle 904 will contact the anti-pull groove and form a limit, preventing the replacement handle 10 from sliding upward. This prevents the activated carbon plate 7 from being replaced by pulling the replacement handle 10 when the device is in working condition, i.e., when the motor 4 is rotating, thus avoiding the danger caused by operator error. When the motor 4 stops rotating, the rotating wheel 902 also stops rotating. After the rotating wheel 902 stops rotating, it disengages from the limit latch 904 and, under the rebound force of the return spring 2, returns the limit latch 904 to its initial state. This releases the limit between the limit latch 904 and the anti-pull groove, allowing the replacement handle 10 to slide to replace the activated carbon plate 7. During the replacement process, the operator pulls the replacement handle 10 to slide the activated carbon plate 7 upwards. After the activated carbon plate 7 slides upwards, the rotating base 905 slides upwards under the rebound force of the return spring 1. The rotating partition 906 and the telescopic partition 907 are moved together to slide upwards at the ends connected to the rotating base 905. Since the ends of the rotating partition 906 and the telescopic partition 907 away from the rotating base 905 are rotatably connected to the sliding base 908 and the sliding base 908 is slidably installed inside the treatment tank 1, the upward sliding of the rotating base 905 causes the sliding base 908 to slide backwards, so that the rotating partition 906 and the telescopic partition 907 are in a vertical state after the movement, thus forming an isolation inside the treatment tank 1, which minimizes the possibility of gas leakage during the replacement of the activated carbon plate 7 after the device stops working.

[0037] After the rotating base 905 slides upward, its bottom disengages from the top of the door opening lever 1101. After disengagement, the door opening lever 1101 rotates counterclockwise under the rebound force of the spiral spring 2. The rotation of the door opening lever 1101 drives the telescopic link to rotate downward. When the telescopic link rotates downward, it drives the sliding door 1102 to slide downward, thereby opening the dust box 807 so that the dust collected inside can be discharged in time. Simultaneously, the sliding of the sliding base 908 drives the rack 1103 to slide, which in turn drives the large gear 1104 to rotate. The rotation of the large gear 1104 drives the large gear 2 1105 to rotate through the gear connecting rod. The rotation of the large gear 2 1105 drives the rack 2 1106 to slide, which in turn drives the U-shaped scraper 1107 to slide. During the sliding process, the U-shaped scraper 1107 scrapes away the dust adhering to the inner wall of the dust box 807. Scraping away the dust accumulated on the inner wall of the dust box 807 prevents the dust from flowing back into the processing tank 1 during operation, thereby improving the processing efficiency of the device and enhancing the stability of the device during long-term operation.

[0038] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
