Description

Technical Field

[0001] This utility model relates to the field of CO2 capture equipment technology, specifically a CO2 capture equipment with easy filter replacement. Background Technology

[0002] Since the world entered the industrial age, the large-scale use of fossil fuels has led to a rapid increase in carbon dioxide emissions. The increase in greenhouse gases has caused various climate changes that are detrimental to human survival. In order to avoid catastrophic climate events, carbon dioxide emission reduction has become one of the most important environmental issues in the world. Therefore, a capture device is needed to collect and process carbon dioxide.

[0003] A search revealed a user-friendly CO2 capture device with publication number CN223112606U. The device involves filtering CO2 through a filter box and then allowing it to enter the collection tank via an inlet pipe. When the filter plate becomes dirty, a lever is moved to one side, causing a retaining plate to disengage from its slot. At this point, a spring plate, under the action of two No. 1 springs, moves forward, pushing the filter plate out of the filter box. A new filter plate is then inserted into the filter box for replacement. This device can filter particulate dust in the exhaust gas, preventing it from affecting subsequent liquefaction processes, and also facilitates quick replacement of the filter plate.

[0004] However, this existing technology has a significant drawback: the fixing and ejection of its filter plates rely entirely on the preload of springs for limiting and driving. While this design may function in a static environment, it inevitably encounters vibrations, impacts, or shaking from the external environment during actual industrial applications or equipment transportation. These external forces can easily cause unexpected compression or deformation of the springs, leading to the failure of the locking mechanism between the plate and the slot, resulting in the filter plates loosening or even automatically detaching. This not only interrupts the collection process and affects the continuous and stable operation of the equipment, but may also cause unfiltered exhaust gas to directly enter subsequent precision treatment units, causing equipment damage or reduced efficiency, posing significant safety and stability risks. Utility Model Content

[0005] The purpose of this invention is to provide a CO2 capture device with an easy-to-replace filter element, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CO2 capture device that facilitates filter replacement, comprising a capture tank, a base installed at the bottom of the capture tank, an air outlet installed at the right end of the capture tank, a filter box installed at the left end of the capture tank, an air inlet installed on the left side of the filter box, a filter plate inserted inside the filter box, a handle fixed to the outer surface of the filter plate, and a connecting component and a limiting component provided on the outer surfaces of the filter box and the handle;

[0007] The connection component includes:

[0008] Fixed frame one, fixed frame one is used to stabilize the internal mechanisms;

[0009] Fixed frame two is used to connect with fixed frame one.

[0010] A clamping plate is used in conjunction with a clamping hole to achieve a limiting position.

[0011] Preferably, the first fixing frame is fixed to the outer surface of the handle, and the outer surface of the first fixing frame has a movable hole. The outer surface of the filter box is fixed to the second fixing frame, and the outer surface of the second fixing frame has a locking hole. A connecting rod is slidably connected to the inner wall of the first fixing frame, and a spring is fixed to the outer surface of the connecting rod. The end of the spring away from the connecting rod is fixed to the inner wall of the first fixing frame. A receiving groove is formed on the outer surface of the connecting rod, and a fixing rod is fixed to the inner wall of the receiving groove. A locking plate is rotatably connected to the inner wall of the receiving groove. The fixing rod passes through the locking plate, and a spiral spring is fixed to the outer surface of the fixing rod. The end of the spiral spring away from the fixing rod is fixed to the inner side of the locking plate. A short rod is fixed to the outer surface of the connecting rod. The end of the short rod away from the connecting rod passes through the first fixing frame, and the short rod is slidably connected to the connecting rod. A pressure plate is fixed to the end of the short rod away from the connecting rod. The first fixing frame is inserted into the second fixing frame, so that the inner wall of the second fixing frame contacts the side of the locking plate away from the plane, pushing the locking plate to flip into the receiving groove. At the same time, the spiral spring rewinds and stores force. When the locking plate moves to align with the locking hole, the spiral spring releases energy, driving the locking plate to reverse and reset, locking into the locking hole. At this point, the flat side of the locking plate is in contact with the inner wall of the locking hole, achieving mutual restraint and facilitating installation and fixation. Under vibration or external interference, the elasticity of the spiral spring maintains the locking state, preventing accidental disengagement. When the plate is pressed, the short rod and connecting rod move accordingly, causing the side of the locking plate away from the flat surface to contact the inner wall of the locking hole, pushing the locking plate to flip and retract into the receiving slot. At this point, the fixing frame can be pulled out by pulling the groove on the handle, achieving disassembly.

[0012] Preferably, the limiting component includes a slide groove, which is formed on the outer surface of the handle. An annular groove is formed on the inner side of the slide groove, and a vertical groove is formed on the inner wall of the slide groove. A slide plate is slidably connected to the inner wall of the slide groove. A spring is fixed to the outer surface of the slide plate, and the end of the spring away from the slide plate is fixed inside the slide groove. A circular block is rotatably connected to the side of the slide plate away from the spring. A baffle is fixed to the outer surface of the circular block. A rotating rod is fixed to the side of the circular block away from the slide plate. The end of the rotating rod away from the circular block passes through a pressure plate, and the rotating rod is rotatably connected to the pressure plate. A movable groove is formed on the side of the circular block away from the rotating rod. A movable column is slidably connected to the inner wall of the movable groove. A spring is fixed to the outer surface of the movable column, and the end of the spring away from the movable column is fixed to the inner wall of the movable groove. A stabilizing groove is formed on the side of the slide plate away from the spring. After installation, the baffle is inserted into the annular groove, and its outer surface fits against the inner wall of the annular groove, limiting the circular block, rotating rod, and pressure plate, thus enhancing overall stability. Rotate the lever to align the baffle with the vertical groove; at the same time, the movable column enters the stabilizing groove to prevent the round block and the lever from rotating on their own. At this time, the pressure plate can be pressed down normally for operation.

[0013] Preferably, the end of the card plate away from the fixing rod is provided with a flat side, which can be used with the card hole to achieve limiting.

[0014] Preferably, the outer surface of the handle has a groove to facilitate gripping.

[0015] Preferably, the end of the movable column away from the second spring is set in an arc shape. When the circular block rotates, the movable column abuts against the inner wall of the stabilizing groove, allowing the movable column to enter the movable groove without affecting the normal rotation of the circular block.

[0016] Compared with the prior art, this utility model provides a CO2 capture device with easy filter replacement, which has the following advantages:

[0017] 1. This CO2 capture device, which facilitates filter replacement, uses a connecting assembly. When installation is required, fixing frame one is inserted into fixing frame two. The inner wall of fixing frame one pushes a retaining plate to flip into the receiving groove, and a spiral spring coils up to store energy. When the retaining plate aligns with the retaining hole, the spiral spring releases energy, driving the retaining plate to flip and engage with the retaining hole, with its flat side fitting against the hole wall for locking and securing. Even under vibration, the spring force maintains the engagement, preventing loosening. For disassembly, pressing the plate, along with the short rod and connecting rod, flips the retaining plate back into the receiving groove, allowing fixing frame one to be pulled out from the groove for easy disassembly and cleaning.

[0018] 2. This CO2 capture device, which facilitates filter replacement, utilizes a limiting component. When the filter plate is installed, the baffle is engaged in the annular groove, with its outer surface fitting against the groove wall, restricting the movement of the circular block, rotating rod, and pressure plate, thus further enhancing stability. During cleaning, rotating the rotating rod aligns the baffle with the vertical groove; the circular block rotates synchronously, pushing the movable column back into the movable groove, compressing the second spring. When the movable column aligns with the stabilizing groove, the second spring pushes it into the groove and locks it in place, preventing rotation. At this point, the pressure plate can be pressed down. Attached Figure Description

[0027] like Figures 1-7As shown, this utility model provides a technical solution: a CO2 capture device with easy filter replacement, including a capture tank 1, a base 2 installed at the bottom of the capture tank 1, an air outlet 3 installed at the right end of the capture tank 1, a filter box 4 installed at the left end of the capture tank 1, an air inlet 5 installed on the left side of the filter box 4, a filter plate 6 inserted inside the filter box 4, a handle 7 fixed on the outer surface of the filter plate 6, and a connecting component 8 and a limiting component 9 provided on the outer surfaces of the filter box 4 and the handle 7; the connecting component 8 includes: a first fixing frame 80, a movable hole 81, a locking hole 82, a connecting rod 83, a receiving groove 84, a locking plate 85, a fixing rod 86, a spiral spring 87, a second fixing frame 88, a short rod 89, a pressure plate 800, and a third spring 801.

[0028] A first fixed frame 80 is fixed to the outer surface of the handle 7. A movable hole 81 is provided on the outer surface of the first fixed frame 80. A second fixed frame 88 is fixed to the outer surface of the filter box 4. A locking hole 82 is provided on the outer surface of the second fixed frame 88. A connecting rod 83 is slidably connected to the inner wall of the first fixed frame 80. A third spring 801 is fixed to the outer surface of the connecting rod 83. The end of the third spring 801 away from the connecting rod 83 is fixed to the inner wall of the first fixed frame 80. A receiving groove 84 is provided on the outer surface of the connecting rod 83. A fixing rod 86 is fixed to the inner wall of the receiving groove 84. A retaining plate 85 is rotatably connected to the inner wall of the receiving groove 84. The fixing rod 86 passes through the retaining plate 85, and a spiral spring 87 is fixed to the outer surface of the fixing rod 86. The end of the spiral spring 87 away from the fixing rod 86 is fixed to the inner side of the retaining plate 85. A short rod 89 is fixed to the outer surface of the connecting rod 83. The end of the short rod 89 away from the connecting rod 83 passes through the fixing frame 80, and the short rod 89 is slidably connected to the connecting rod 83. The end of the short rod 89 away from the connecting rod 83 is fixed. A pressure plate 800 is provided, and the end of the clamping plate 85 away from the fixing rod 86 is provided with a flat side. The first fixing frame 80 is inserted into the second fixing frame 88, so that the inner wall of the second fixing frame 88 contacts the side of the clamping plate 85 away from the flat side, pushing the clamping plate 85 to flip and enter the receiving groove 84. At the same time, the spiral spring 87 winds up and stores energy. When the clamping plate 85 moves to align with the clamping hole 82, the spiral spring 87 releases energy, driving the clamping plate 85 to reverse and reset and clamp into the clamping hole 82. At this time, the flat side of the clamping plate 85 and the clamping hole 82 are aligned. The inner walls fit together, allowing for mutual positioning of the first fixed frame 80 and the second fixed frame 88, facilitating installation and fixation. When vibration or external interference causes displacement of the connecting rod 83, the elasticity of the spiral spring 87 maintains the engagement of the locking plate 85 and the locking hole 82, effectively preventing accidental disengagement and improving connection stability. When the pressure plate 800 is pressed, the short rod 89 and the connecting rod 83 move accordingly, causing the side of the locking plate 85 away from the plane to contact the inner wall of the locking hole 82, pushing the locking plate 85 to flip and retract into the receiving groove 84. At this point, by pulling outwards through the groove on the gripping handle 7, the first fixed frame 80 can be pulled out of the second fixed frame 88 for disassembly and cleaning. After releasing the pressure plate 800, the third spring 801 releases its elastic force, resetting all related mechanisms and preparing for subsequent reinstallation.

[0029] The limiting component 9 includes a slide groove 90, which is formed on the outer surface of the handle 7. An annular groove 91 is formed on the inner side of the slide groove 90, and a vertical groove 92 is formed on the inner wall of the slide groove 90. A slide plate 93 is slidably connected to the inner wall of the slide groove 90. A spring 94 is fixed to the outer surface of the slide plate 93. The end of the spring 94 away from the slide plate 93 is fixed inside the slide groove 90. A circular block 95 is rotatably connected to the side of the slide plate 93 away from the spring 94. A baffle 96 is fixed to the outer surface of the circular block 95. A rotating rod 97 is fixed to the side of the circular block 95 away from the slide plate 93. The end of the rotating rod 97 away from the circular block 95 passes through a pressure plate 800, and the rotating rod 97 is connected to the pressure plate. The filter plate 800 is rotatably connected. A movable groove 98 is provided on the side of the circular block 95 away from the rotating rod 97. A movable column 99 is slidably connected to the inner wall of the movable groove 98. A second spring 900 is fixed to the outer surface of the movable column 99. The end of the second spring 900 away from the movable column 99 is fixed to the inner wall of the movable groove 98. A stabilizing groove 901 is provided on the side of the sliding plate 93 away from the first spring 94. The end of the movable column 99 away from the second spring 900 is arc-shaped. After installation, the baffle 96 is inserted into the annular groove 91, with its outer surface fitting against the inner wall of the annular groove 91, thus limiting the movement of the circular block 95, the rotating rod 97, and the pressure plate 800, enhancing overall stability. When cleaning the filter plate 6, the rotating rod 97 is rotated to align the baffle 96 with the vertical groove 92; simultaneously, the circular block 95 rotates to push the movable column 99, causing its outer surface to contact the inner wall of the stabilizing groove 901. The movable column 99 retracts into the movable groove 98, and the second spring 900 contracts under pressure. When the movable column 99 is aligned with the stabilizing groove 901, the spring 900 releases its thrust, pushing the movable column 99 into the stabilizing groove 901 to prevent the round block 95 and the rotating rod 97 from rotating on their own. At this point, the pressure plate 800 can be pressed down normally for operation. The outer surface of the handle 7 has a groove for easy gripping.

[0030] When filter plate 6 needs to be installed, insert filter plate 6 into filter box 4 so that handle 7 is in contact with the outer surface of filter box 4. At this time, fixing frame 1 80 enters fixing frame 2 88. The inner wall of fixing frame 2 88 abuts against the side of clamping plate 85 away from the plane, which allows clamping plate 85 to flip into receiving groove 84. At this time, spiral spring 87 is wound up. When the position of clamping plate 85 is parallel to clamping hole 82, spiral spring 87 is released, which drives clamping plate 85 to reverse and reset into clamping hole 82. At this time, the plane side of clamping plate 85 abuts against the inner side of clamping hole 82. The contact mechanism allows the fixed frame 80 and the fixed frame 88 to mutually limit each other, facilitating installation. When vibration or external factors cause the connecting rod 83 to move, the spiral spring 87 ensures that the locking plate 85 remains within the locking hole 82, preventing accidental disengagement and improving stability. Simultaneously, upon completion of installation, the baffle 96 enters the annular groove 91, with its outer surface abutting against the inner wall of the annular groove 91, thus limiting the circular block 95, the rotating rod 97, and the pressure plate 800, further enhancing the stability of the limiting mechanism. During use, it is connected via the air inlet 5. The exhaust gas is filtered through filter plate 6, allowing carbon dioxide gas to enter the collection tank 1 for collection. When filter plate 6 needs cleaning, the rotating rod 97 is rotated so that the baffle 96 is parallel to the vertical groove 92. Simultaneously, as the circular block 95 rotates, it drives the movable column 99 to move. At this time, the outer surface of the movable column 99 abuts against the inner wall of the stabilizing groove 901, causing the movable column 99 to move into the movable groove 98, compressing the spring 900. When the movable column 99 is parallel to the stabilizing groove 901, the spring 900 is released, which can then drive... When the movable column 99 enters the stabilizing groove 901, it can prevent the circular block 95 and the rotating rod 97 from rotating on their own. At this time, the pressing plate 800 can be pressed normally. At this time, the short rod 89 and the connecting rod 83 move. At this time, the clamping plate 85 is away from the plane and abuts against the inner wall of the clamping hole 82, so that the clamping plate 85 can enter the receiving groove 84. At this time, by pulling outward by the groove of the gripping handle 7, the first fixing frame 80 can be separated from the second fixing frame 88, which can be removed for easy cleaning. When the pressing plate 800 is released, the third spring 801 is released, which drives the mechanism to reset, which facilitates the subsequent installation work.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
