Description

Technical Field

[0001] The invention relates to the technical field of waste gas dust removal, and in particular to energy-saving waste gas purification and environmentally friendly dust removal equipment. Background Art

[0002] Most of the existing waste gas is passed through the filter plate of the dust removal equipment to remove particulate matter in the waste gas. However, when the filter plate in the current dust removal equipment is replaced, it is mostly necessary to stop the injection of waste gas and shut down the dust removal equipment for replacement.

[0003] The Chinese invention patent with publication number CN118634589A discloses an energy-saving waste gas purification and environmentally friendly dust removal equipment, which relates to the field of waste gas dust removal technology and has the advantage of not having to stop the waste gas injection when replacing the filter plate. The key points of the technical solution are: it includes a mounting barrel and an exhaust pipe connected to the bottom end of the mounting barrel, the mounting barrel is provided with a cover plate for closing the barrel mouth of the mounting barrel, a baffle ring is rotatably connected to the inner wall of the exhaust pipe, a baffle plate is provided on the inner wall of the baffle ring, a partition plate is provided on the top of the baffle plate to divide the mounting barrel into a right filtering area and a left filtering area, two filter plates respectively located in the right filtering area and the left filtering area are vertically slidably connected on the partition plate, a disassembly mechanism for removing one of the filter plates from the mounting barrel is provided on the cover plate, a U-shaped air guide pipe connecting the right filtering area with the left filtering area is provided on the mounting barrel, a stop valve is provided on one end of the air guide pipe close to the right filtering area, an air inlet pipe is connected to the air guide pipe, and a driving member for driving the baffle ring to rotate is provided on the mounting barrel.

[0004] However, the above patent still has the following shortcomings in actual use: 1. This patent can replace the filter plate without stopping the injection of exhaust gas. When installing a new filter plate, the filter plate needs to be placed in the box body first, and then the arc plate on the top of the filter plate needs to be installed in the slide groove at the bottom of the embedded plate. Then the embedded plate, the arc plate, and the filter plate are driven by the electric cylinder to move downward synchronously. During the downward movement, the slide on the side wall of the filter plate needs to be installed on the slide seat of the partition plate. Therefore, the installation position of the filter plate must be precise. However, the embedded plate cannot position the filter plate. Once the filter plate is offset, it cannot be installed on the partition plate. The replacement method of this patent cannot ensure that the filter plate can be replaced stably; 2. When replacing the filter plate, although the right filter area is in a closed state, there is still some exhaust gas in the right filter area. Once the embedded plate moves up, this part of the exhaust gas will also enter the box body. Once the door body is opened, the exhaust gas in the box body will flow into the outside air, causing invisible pollution. Summary of the invention

[0005] In order to make up for the above shortcomings, the present invention provides an energy-saving exhaust gas purification and environmentally friendly dust removal equipment to solve the problems raised in the above background technology on how to stably replace the filter plate and how to avoid the exhaust gas from accidentally flowing into the outside air during the replacement of the filter plate.

A cover body 71 for closing the opening is hingedly installed on the top, a magnetic layer is provided at the bottom of the cover body 71, an adsorption layer cooperating with the magnetic layer is provided on the top of the box body 7, an extraction mechanism 8 for extracting air from the box body 7 is provided at the head end of the box body 7, a first electric push rod 72 arranged horizontally is also provided at the head end of one of the box bodies 7, an output end of the first electric push rod 72 is fixedly connected to one end of the translation plate 2, a locking mechanism 9 for selectively locking the cover body 71 is also provided at the top of the head end of the slide frame 6, a connecting foot 34 is provided at the bottom of the filter box 3 and the two box bodies 7, and a water tank 4 is provided with a partition 41, which divides the interior of the water tank 4 into a first water area 42 and a second water area 43. A water outlet pipe 44 and a water inlet pipe 45 are provided on both sides of the water tank 4. A solenoid valve 46 is provided on the water outlet pipe 44 and the water inlet pipe 45. A switching mechanism 10 is provided in the first water area 42 for selectively discharging the gas discharged from the air outlet pipe 32 into the first water area 42 or the second water area 43. All connecting legs 34 are fixedly connected to the top of the water tank 4. The air outlet pipe 32 passes through the top of the water tank 4 and extends into the first water area 42. The air outlet pipe 32 is connected to the switching mechanism 10.

[0035] The present invention drives the translation plate 2 to translate by the first electric push rod 72, so that the two filter plates 11 on the translation plate 2 can be switched. During translation, only a small amount of exhaust gas is retained in the rectangular frame 1. The retained exhaust gas can be extracted by the extraction mechanism 8 to avoid accidental flow of exhaust gas into the outside air, thereby improving environmental protection. The outer convex plate 12, the rectangular frame 1, and the filter plate 11 can be automatically separated from the installation groove by the telescopic mechanism 5, thereby facilitating removal and improving convenience. During installation, only the rectangular frame 1 needs to be inserted into the rectangular block 22. The installation is convenient and quick, and the filter plate 11 is prevented from shifting left and right.

[0036] The translation plate 2 separates the filter box 3. The exhaust gas enters the filter box 3 from the air inlet pipe 31, and then is filtered by the filter plate 11 located in the filter box 3. The exhaust gas then enters the lower part of the filter box 3 and is then discharged from the air outlet pipe 32. When the filter plate 11 located in the filter box 3 needs to be replaced, the first electric push rod 72 drives the translation plate 2 to move, and the translation plate 2 drives the two filter plates 11 to move synchronously. One of the two filter plates 11 is not replaced, and the other is replaced. The unreplaced filter plate 11 moves with the rectangular Frame 1 enters into the sliding frame 6 together, and then enters into the box body 7. Once the outer convex plate 12 is separated from the sliding frame 6, the telescopic mechanism 5 starts to work. The telescopic mechanism 5 includes a telescopic ring body 51 and a plurality of first springs 52. The bottom of the telescopic ring body 51 is provided with a built-in groove. The telescopic ring body 51 is slidably set in the rectangular ring groove 23. All the first springs 52 are evenly distributed in the rectangular ring groove 23, and the top of the first spring 52 is in contact with the top of the built-in groove, and the top of the telescopic ring body 51 is in contact with the outer convex plate 12.

[0037] When the outer convex plate 12 is separated from the sliding frame 6, the limiting abutment force is lost, so the elastic force of the first spring 52 can drive the telescopic ring body 51 to extend upward in the rectangular ring groove 23, and the telescopic ring body 51 abuts against the outer convex plate 12 and moves upward synchronously. The outer convex plate 12 drives the rectangular frame 1 and the unreplaced filter plate 11 to move upward synchronously. In order to prevent the telescopic ring body 51 from accidentally detaching from the rectangular ring groove 23, four rectangularly distributed guide blocks 511 are provided on the outer wall of the telescopic ring body 51, and four guide grooves 24 slidingly matched with the guide blocks 511 are opened on the groove wall of the mounting groove.

[0038] At the same time, when the other end of the translation plate 2 drives another outer convex plate 12 to enter the sliding frame 6, the first wedge surface 121 at the rear end of the outer convex plate 12 and the second wedge surface 61 of the sliding frame 6 cooperate to drive the outer convex plate 12 to move downward as a whole, and the outer convex plate 12 can drive the rectangular frame 1 and the replaced filter plate 11 to move downward synchronously, and all the first springs 52 are compressed, and then the outer convex plate 12 can be completely embedded in the installation groove. When the replaced filter plate 11 enters the filter box 3, the top of the inner sliding groove 33 can abut against the two side edges of the outer convex plate 12 to ensure that the outer convex plate 12 can be firmly fixed in the installation groove.

[0039] The rectangular frame 1 carries part of the waste gas, which can be extracted by the extraction mechanism 8. The extraction mechanism 8 includes two extraction components symmetrically arranged on the box body 7. The extraction component includes an extraction cylinder 81 and an extraction rod 82. An air outlet head 811 and an air inlet elbow 812 are arranged on the outer wall of the tail end of the extraction cylinder 81. An air outlet check valve is arranged in the air outlet head 811, and an air inlet check valve 813 is arranged in the air inlet elbow 812. A first sliding hole is opened at the head end of the extraction cylinder 81, and an abutment block 83 is installed at the tail end of the extraction rod 82. A limit plate 84 is arranged at the head end of the extraction rod 82, and a plug body 85 is arranged in the middle of the extraction rod 82. The head end of 82 is also sleeved with a second spring 86, and two connecting heads 35 connected to the interior thereof are provided on both sides of the filter box 3. Two second sliding holes slidably matched with the extraction rod 82 are provided on the outer wall of the head end of the box body 7. The extraction cylinder 81 is horizontally connected to the outer wall of the head end of the box body 7. The extraction rod 82 is slidably set in the first sliding hole and the second sliding hole. The abutment block 83 is located in the box body 7, and the plug body 85 is slidably set in the extraction cylinder 81. The two ends of the second spring 86 are respectively abutted against the box body 7 and the limit plate 84. The air outlet head 811 is connected to one of the connecting heads 35 through a pipeline, and the air inlet elbow 812 is connected to the interior of the box body 7.

[0040] One end of the translation plate 2 gradually abuts against the abutment block 83, the abutment block 83 drives the extraction rod 82 to move, the extraction rod 82 drives the plug body 85 and the limit plate 84 to move synchronously, and the plug body 85 can generate an extraction force when moving in the extraction cylinder 81. Due to the arrangement of the air outlet check valve and the air inlet check valve 813, the extraction force can draw the gas and exhaust gas inside the box body 7 into the extraction cylinder 81, and the limit plate 84 can drive the second spring 86 to become a stretched state. At the same time, the other end of the translation plate 2 will gradually move away from the corresponding abutment block 8 3, the corresponding second spring 86 gradually recovers from the stretched state to the initial state, the tension of the second spring 86 can drive the limit plate 84 to move in the opposite direction, the limit plate 84 drives the extraction rod 82, the plug 85 and the abutment block 83 to move in the opposite direction, the plug 85 can generate an extrusion force when moving in the extraction cylinder 81, due to the setting of the outlet check valve and the inlet check valve 813, the extrusion force can squeeze the gas and the exhaust gas in the extraction cylinder 81 through the pipeline into the upper half of the filter box 3, thereby preventing the exhaust gas from entering the outside air.

[0041] Furthermore, a horizontally arranged auxiliary block 73 is provided on the inner wall of the head end of the box body 7, and an eighth wedge surface 731 is provided on the top of one end of the auxiliary block 73 away from the inner wall of the head end of the box body 7, and a ninth wedge surface 122 cooperating with the eighth wedge surface 731 is provided at the head end of the outer convex plate 12.

[0042] After the outer convex plate 12 moves upward, the bottom of the outer convex plate 12 is still attached to the top of the telescopic ring body 51. It is still difficult for workers to take out the outer convex plate 12. When the outer convex plate 12 moves simultaneously with the translation plate 2, the ninth wedge surface 122 can gradually approach the eighth wedge surface 731 on the auxiliary block 73. Then, the wedge surface cooperation can make the outer convex plate 12 move upward for a distance, so that a gap is generated between the outer convex plate 12 and the telescopic ring body 51. Workers can use this gap to find a force point for convenient removal of the outer convex plate 12, thereby improving the convenience of removing the outer convex plate 12, that is, facilitating the removal of the unreplaced filter plate 11.

[0043] When the air in the box body 7 is sucked out, the air in the box body 7 is sucked out of the box body 7, and the air in the box body 7 is sucked out of the box body 7. When the air in the box body 7 is sucked out, the air in the box body 7 is sucked out of the box body 7, and the air in the box body 7 is sucked out of the box body 7. When the air in the box body 7 is sucked out, the air in the box body 7 is sucked out of the box body 7, and the air in the box body 7 is sucked out of the box body 7. A vertical rod 95 is provided for sliding inside 92, a fourth wedge surface 951 is provided on the top of the vertical rod 95 for cooperating with the third wedge surface 941, a limiting convex plate 952 is provided on the upper part of the vertical rod 95, a fourth spring 953 is provided between the limiting convex plate 952 and the vertical sliding seat 92, a fifth wedge surface 954 is provided on one side of the bottom of the vertical rod 95, a round convex head 955 is provided on the other side of the bottom of the vertical rod 95, a plug-in groove 931 cooperating with the plug-in block 944 is provided on the side wall of the locking block 93, and both ends of the translation plate 2 are locked. A sixth wedge surface 25 cooperating with the round convex head 955 is provided on the top, and four embedding grooves 26 distributed in a rectangular shape and for the bottom of the vertical rod 95 to be embedded are provided on the translation plate 2. A seventh wedge surface 261 cooperating with the fifth wedge surface 954 is provided in the embedding groove 26. The horizontal sliding seat 91 is fixedly connected to the side wall of the vertical plate 62, one end of the third spring 943 is fixedly connected to the side wall of the vertical plate 62, the vertical sliding seat 92 is fixedly connected to the inner wall of the box body 7, and the locking block 93 is connected to the bottom of the cover body 71.

[0044] Reference Figure 4 , Figure 7-Figure 9When one end of the translation plate 2 enters the box body 7, the sixth wedge surface 25 on one end of the translation plate 2 gradually conflicts with the round convex head 955, and the sixth wedge surface 25 cooperates with the wedge surface of the round convex head 955 to drive the vertical rod 95 to move up on the vertical sliding seat 92. Then, the bottom of the vertical rod 95 conflicts with the top of the translation plate 2. After the vertical rod 95 moves up, it drives the limiting convex plate 952 to move up synchronously, and the fourth spring 953 is stretched.
