[0004] During the connection or disassembly of the conveying pipe and the guide pipe, traditional bolt or flange connection methods require special tools, the disassembly and assembly steps are cumbersome, and the connection parts gradually loosen due to vibration after long-term operation of the equipment. This leads to problems such as long maintenance time, increased risk of coolant leakage, and unstable coke oven gas cooling effect. Summary of the Invention

[0005] The purpose of this invention is to solve the shortcomings of the existing technology in the process of connecting or disassembling the conveying pipe and the guide pipe. Traditional bolt or flange connection methods require special tools, the disassembly and assembly steps are cumbersome, and the connection parts gradually loosen due to vibration after long-term operation of the equipment. This leads to long maintenance time, increased risk of coolant leakage, and unstable coke oven gas cooling effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-stage cooling coupled deep impurity removal device for coke oven gas, comprising a body, a connecting device, and a locking device. An inlet pipe is provided on one end surface of the body, an outlet pipe is provided on one end surface of the body, a guide pipe is provided inside the body, and a conveying pipe is fixedly connected to the input end of the guide pipe via the connecting device. A coolant tank is rotatably connected to one end of the conveying pipe, a motor is provided on one end surface of the coolant tank, a condenser is provided on one end surface of the body, and several carbon adsorption layers are provided on one end surface of the body. The connecting device is located at the conveying pipe... The connecting device includes a fixed plate, one end of which is fixedly connected to the arc surface of the conveying pipe. The fixed plate has an "L" shaped cross-section. A connecting ring is fixedly connected to the arc surface of the inlet end of the guide pipe. The connecting ring has a "C" shaped cross-section. The surface of the fixed plate is slidably connected to the surface of the opening of the connecting ring. A sliding groove is provided on the arc surface of the connecting ring. A sliding block is fixedly connected to the surface of the long arm end of the fixed plate. The sliding block is an iron block. A sliding rod slides through the upper surface of the connecting ring. A fixed ring is threadedly connected to the arc surface of the bottom end of the sliding rod.

[0007] The effects achieved by the above components are as follows: by setting up a connecting device, utilizing the sliding fit between the fixed plate and the connecting ring, and the locking effect between the sliding rod and the fixed ring, quick assembly and disassembly between the delivery pipe and the guide pipe are realized, improving the assembly efficiency and sealing stability of the coolant delivery path, and facilitating maintenance and replacement.

[0008] Preferably, a magnetic block is fixedly connected to the inner wall of the sliding groove, and one end surface of the magnetic block is attracted to one end surface of the sliding block.

[0009] The effect achieved by the above components is as follows: by setting magnetic blocks in the sliding groove, the sliding blocks are automatically attracted and fixed after insertion, which enhances the positioning reliability during connection, prevents the sliding blocks from accidentally coming off due to working vibration, and improves the shock resistance of the connection device.

[0010] Preferably, a guide block is fixedly connected to the upper surface of the sliding block, a guide groove is formed on the inner wall of the sliding groove, and the surface of the guide block is slidably connected to the inner wall of the guide groove.

[0011] The effect achieved by the above components is as follows: through the sliding cooperation between the guide block and the guide groove, the movement path of the sliding block is limited and guided, avoiding installation deviation, ensuring accurate alignment between the fixed plate and the opening of the connecting ring, and making the connection process smoother and more stable.

[0012] Preferably, a friction pad is fitted onto the bottom arc surface of the sliding rod, one end surface of the friction pad abuts against one end surface of the connecting ring, and the other end surface of the friction pad abuts against one end surface of the fixing ring, wherein the friction pad is a rubber pad.

[0013] The effect achieved by the above components is as follows: by fitting a rubber friction pad at the bottom of the sliding rod and pressing it against the surface of the connecting ring by the fixing ring, the friction of the contact surface is increased, effectively preventing the fixing ring from loosening due to vibration and improving the anti-loosening ability of the threaded connection.

[0014] Preferably, a collection device is provided on one end surface of the machine body at the position corresponding to the output end of the guide pipe by means of a locking device. The collection device includes a collection box, which is disposed on one end surface of the machine body. Four rollers are rotatably connected to the bottom surface of the collection box. A clamping assembly is provided on one side of the upper surface of the collection box. The clamping assembly includes a fixing frame, the bottom surface of which is fixedly connected to the upper surface of the collection box. Rotating rods are threaded through both ends of the fixing frame. A clamping plate is rotatably connected to one end surface of the rotating rod. The clamping plate has a "C" shaped cross section, and one end surface of the clamping plate abuts against the arc surface of the output end of the guide pipe.

[0015] The effect achieved by the above components is as follows: by setting up a collection device, using a collection box with rollers and a rotating rod and C-shaped clamp in the clamping assembly, the collection box can be quickly fixed at the output end of the guide pipe, realizing the centralized collection of impurities or liquids precipitated after cooling, which is convenient for subsequent processing.

[0016] Preferably, a handle is fixedly connected to one end surface of the collection box, the handle has a "U" shaped cross section, and an anti-slip sleeve is fitted on the arc surface of one end of the handle.

[0017] The effect achieved by the above components is as follows: by setting a U-shaped handle and covering it with an anti-slip sleeve at one end of the collection box, it is easy for operators to push and pull the collection box. The anti-slip sleeve increases the hand friction, preventing slippage in wet and slippery environments, and improving the comfort and safety of operation.

[0018] Preferably, a plurality of anti-slip patterns are formed on the arc surface of one end of the rotating rod, and the plurality of anti-slip patterns are evenly distributed on the arc surface of one end of the rotating rod.

[0019] The effect achieved by the above components is as follows: by evenly opening multiple anti-slip textures on the arc surface of the rotating rod, the friction between the fingers or tools and the rotating rod is increased, making it easy to rotate by hand, clamping or loosening without additional tools, and improving the convenience of adjustment.

[0020] Preferably, the locking device is disposed on one end surface of the body, and the locking device includes two auxiliary plates, which are respectively fixedly connected to the two end surfaces of the collection box. A rod is slidably inserted through one end surface of the auxiliary plate, and a spring is sleeved on the arc surface of the rod. The two ends of the spring are respectively fixedly connected to one end surface of the rod and one end surface of the auxiliary plate. The arc surface of the rod is slidably inserted into one end surface of the body. Limiting blocks are fixedly connected to both sides of one end surface of the body. Limiting grooves are formed on both sides of one end surface of the collection box. The surface of the limiting block is slidably connected to the inner wall of the limiting groove. Limiting plates are fixedly connected to both sides of one end surface of the body, and the upper end surface of the limiting plate abuts against the bottom end surface of the collection box.

[0021] The effect achieved by the above components is as follows: by setting a locking device, using a spring-driven plug rod to connect with the machine body, combined with the guiding effect of the limit block and the limit groove, and the support of the limit plate on the bottom of the collection box, the collection box can be quickly positioned and released for locking, preventing displacement during operation, and facilitating disassembly and emptying.

[0022] Preferably, a guide block is fixedly connected to the bottom surface of the insertion rod, and the cross-section of the guide block is conical.

[0023] The effect achieved by the above components is as follows: by setting a pointed cone-shaped guide block at the bottom of the insertion rod, it can automatically center and guide when the corresponding hole on the body surface is inserted, reducing the difficulty of alignment. Even if there is a slight deviation, it can be inserted smoothly, improving the convenience of locking operation.

[0024] Preferably, a pull ring is rotatably connected to one end surface of the insertion rod, and the pull ring is a hard alloy ring.

[0025] The effect achieved by the above components is that by rotating a pull ring made of hard alloy at one end of the insertion rod, it is easy to hook the pull ring with a finger to overcome the spring force and pull out the insertion rod. The hard alloy ring is wear-resistant and has high strength, and can be reused for a long time.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, a connecting device is used to provide initial guidance for the assembly of the delivery pipe and the guide pipe by sliding an L-shaped fixing plate with a C-shaped connecting ring opening. Simultaneously, a guide block on the sliding block engages with a guide groove on the inner wall of the sliding groove to ensure the sliding block does not deviate during insertion. A sliding rod passes through the connecting ring and is threaded to the fixing ring, with a rubber friction pad fitted at the bottom of the sliding rod, pressing the fixing ring tightly against the friction pad on the connecting ring surface, effectively preventing loosening due to vibration. Furthermore, the magnetic block on the inner wall of the sliding groove and the iron sliding block attract each other, further enhancing the reliability of temporary positioning after installation. These structures collectively achieve a quick, precise, and secure connection between the guide pipe and the delivery pipe, significantly improving the assembly and disassembly efficiency and sealing stability of the coolant delivery path, and reducing maintenance difficulty.

[0027] 2. In this invention, a collection device is installed on the machine body surface at the position corresponding to the output end of the guide pipe, with a collection box equipped with four rollers for easy movement and replacement. The upper end of the collection box is equipped with a clamping assembly consisting of a fixed frame, a rotating rod, and a C-shaped clamping plate. By rotating the rotating rod, the clamping plate can be tightly pressed against the arc surface of the guide pipe output end, thereby quickly fixing the collection box at the guide pipe outlet, achieving reliable clamping even with different pipe diameters. The evenly distributed anti-slip texture on the rotating rod facilitates hand operation, while the U-shaped handle and anti-slip sleeve at one end of the collection box facilitate pushing and pulling by the operator. This device can effectively collect condensate or solid impurities precipitated from coke oven gas after multi-stage cooling, preventing leakage and environmental pollution, while also facilitating periodic emptying and improving the continuous operation capability of the impurity removal device.

[0028] 3. In this invention, a locking device is used. Auxiliary plates are fixed at both ends of the collection box. A sliding insertion rod is mounted on the auxiliary plates, and a spring is fitted onto the rod. A pointed cone-shaped guide block is provided at the bottom of the insertion rod, allowing it to smoothly insert into the corresponding hole in the machine body for quick locking. The spring always provides a preload force to the insertion rod towards the machine body, preventing it from coming loose due to vibration. Simultaneously, limiting blocks fixedly connected to both sides of the machine body slide in a vertically engaged manner with limiting grooves on both sides of the collection box. When the collection box is placed from top to bottom, the limiting blocks vertically insert into the limiting grooves, providing vertical guidance and lateral limitation for the installation direction of the collection box, ensuring that the collection box does not shift horizontally. The limiting plates on the machine body surface provide support for the bottom of the collection box, ensuring that the collection boxes are at the same height when connected. When disassembly is required, simply pull the pull ring at one end of the insertion rod to overcome the spring force and pull it out. The pull ring is made of hard alloy, which is wear-resistant, high-strength, and can be reused for a long time. This locking device enables rapid positioning, reliable locking, and one-button unlocking of the collection box on the machine body, significantly reducing the auxiliary time for replacing the collection box and ensuring the positional stability of the collection box during long-term operation.

[0031] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0033] like Figure 1-11 As shown, the present invention provides a multi-stage cooling coupled deep impurity removal device for coke oven gas, including a body 1, a connecting device 7, and a locking device 9. An air inlet pipe 2 is provided on one end surface of the body 1, an air outlet pipe 10 is provided on one end surface of the body 1, a guide pipe 5 is provided inside the body 1, a conveying pipe 6 is fixedly connected to the input end of the guide pipe 5 by means of the connecting device 7, a coolant tank 3 is rotatably connected to one end of the conveying pipe 6, a motor 4 is provided on one end surface of the coolant tank 3, a condenser 11 is provided on one end surface of the body 1, a plurality of carbon adsorption layers 12 are provided on one end surface of the body 1, the connecting device 7 is provided on the arc surface of one end of the conveying pipe 6, and a collection device 8 is provided on one end surface of the body 1 corresponding to the output end of the guide pipe 5 by means of the locking device 9. The locking device 9 is provided on one end surface of the body 1.

[0034] The specific configuration and function of its connecting device 7, collecting device 8 and locking device 9 will be described in detail below.

[0035] like Figure 2 , Figure 3 Figure 4 and Figure 5As shown, the connecting device 7 includes a fixing plate 703. One end surface of the fixing plate 703 is fixedly connected to the arc surface of one end of the conveying pipe 6. The cross-section of the fixing plate 703 is "L"-shaped. A connecting ring 701 is fixedly connected to the arc surface of one end of the guide pipe 5. The cross-section of the connecting ring 701 is "C"-shaped. The surface of the fixing plate 703 is slidably connected to the surface of the opening of the connecting ring 701. A sliding groove 702 is provided on the arc surface of the connecting ring 701. A sliding block 704 is fixedly connected to one end surface of the long arm end of the fixing plate 703. The sliding block 704 is an iron block. The upper surface of the connecting ring 701 slides through... A sliding rod 708 is threaded onto the bottom arc surface of the sliding rod 708, and a fixing ring 710 is threaded onto it. By setting up a connecting device 7, and utilizing the sliding fit between the fixing plate 703 and the connecting ring 701, as well as the locking action between the sliding rod 708 and the fixing ring 710, quick assembly and disassembly between the delivery pipe 6 and the guide pipe 5 are achieved. This improves the assembly efficiency and sealing stability of the coolant delivery path, and facilitates maintenance and replacement. A magnetic block 707 is fixedly connected to the inner wall of the sliding groove 702. One end surface of the magnetic block 707 is attracted to one end surface of the sliding block 704. By setting the magnetic block inside the sliding groove 702... 707 allows the sliding block 704 to automatically adhere and fix itself after insertion, enhancing the positioning reliability during connection, preventing accidental dislodgement of the sliding block 704 due to operational vibration, and improving the shock resistance of the connecting device 7. A guide block 705 is fixedly connected to the upper surface of the sliding block 704, and a guide groove 706 is formed on the inner wall of the sliding groove 702. The surface of the guide block 705 is slidably connected to the inner wall of the guide groove 706. Through the sliding cooperation between the guide block 705 and the guide groove 706, the movement path of the sliding block 704 is limited and guided, avoiding installation misalignment and ensuring the connection between the fixing plate 703 and the connecting ring 701. Precise alignment at the opening makes the connection process smoother and more stable. A friction pad 709 is fitted on the bottom arc surface of the sliding rod 708. One end surface of the friction pad 709 abuts against one end surface of the connecting ring 701, and the other end surface of the friction pad 709 abuts against one end surface of the fixing ring 710. The friction pad 709 is a rubber pad. By fitting a rubber friction pad 709 at the bottom of the sliding rod 708 and pressing it against the surface of the connecting ring 701 by the fixing ring 710, the friction of the contact surface is increased, effectively preventing the fixing ring 710 from loosening due to vibration and improving the anti-loosening ability of the threaded connection.

[0036] like Figure 6 and Figure 7As shown, the collection device 8 includes a collection box 81, which is disposed on one end surface of the body 1. Four rollers 82 are rotatably connected to the bottom surface of the collection box 81. A clamping assembly 85 is disposed on one side of the upper surface of the collection box 81. The clamping assembly 85 includes a fixing frame 851, the bottom surface of which is fixedly connected to the upper surface of the collection box 81. Rotating rods 852 are threaded through both ends of the fixing frame 851. A clamping plate 853 is rotatably connected to one end surface of the rotating rod 852. The clamping plate 853 has a "C" shaped cross section, and one end surface of the clamping plate 853 abuts against the arc surface of the output end of the guide pipe 5. By setting up the collection device 8, using the collection box 81 with rollers 82 and the rotating rod 852 and C-shaped clamping plate 853 in the clamping assembly 85, the collection box 81 can be quickly fixed to the output end of the guide pipe 5, thereby realizing the collection of impurities precipitated after cooling. The collection of substances or liquids facilitates subsequent processing. A handle 83 is fixedly connected to one end of the collection box 81. The handle 83 has a "U"-shaped cross-section, and an anti-slip sleeve 84 is fitted on the arc surface of one end of the handle 83. By setting a U-shaped handle 83 and a non-slip sleeve 84 on one end of the collection box 81, it is easy for the operator to push and pull the collection box 81. The anti-slip sleeve 84 increases the hand friction, preventing slippage in wet and slippery environments, and improving the comfort and safety of operation. Several anti-slip patterns 854 are evenly distributed on the arc surface of one end of the rotating rod 852. By evenly opening multiple anti-slip patterns 854 on the arc surface of the rotating rod 852, the friction between the fingers or tools and the rotating rod 852 is increased, making it easy to rotate by hand. It can clamp or release without additional tools, improving the convenience of adjustment.

[0037] like Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the locking device 9 includes two auxiliary plates 91, which are fixedly connected to the two end surfaces of the collection box 81. A rod 92 slides through one end surface of each auxiliary plate 91. A spring 93 is fitted onto the arc surface of the rod 92. The two ends of the spring 93 are fixedly connected to one end surface of the rod 92 and one end surface of the auxiliary plate 91, respectively. The arc surface of the rod 92 slides into one end surface of the body 1. Limiting blocks 96 are fixedly connected to both sides of one end surface of the body 1. Limiting grooves 97 are formed on both sides of one end surface of the collection box 81. The surface of the limiting blocks 96 slides into the inner wall of the limiting grooves 97. Limiting plates 98 are fixedly connected to both sides of one end surface of the body 1. The upper surface of the limiting plates 98 abuts against the bottom surface of the collection box 81. By setting the locking device 9, the rod 92 driven by the spring 93 engages with the body 1, thus locking the rod 92. The guiding function of the positioning block 96 and the limiting groove 97, as well as the support of the limiting plate 98 for the bottom of the collection box 81, realize the quick positioning and releaseable locking of the collection box 81, preventing displacement during operation and facilitating disassembly and emptying. A guide block 95 is fixedly connected to the bottom surface of the insertion rod 92. The cross-section of the guide block 95 is conical. By setting the conical guide block 95 at the bottom of the insertion rod 92, it can automatically center and guide when the corresponding hole on the surface of the body 1 is inserted, reducing the difficulty of alignment. Even if there is a slight deviation, it can be inserted smoothly, improving the convenience of locking operation. A pull ring 94 is rotatably connected to one end of the insertion rod 92. The pull ring 94 is a hard alloy ring. By rotatably connecting the pull ring 94 made of hard alloy to one end of the insertion rod 92, it is easy for the finger to hook the pull ring 94 to overcome the force of the spring 93 and pull out the insertion rod 92. The hard alloy ring is wear-resistant and has high strength, and can be reused for a long time.

[0038] The overall working principle is as follows: When connecting the input end of the delivery pipe 6 to the guide pipe 5, the operator first holds the L-shaped fixing plate 703 at the end of the delivery pipe 6, aligns the sliding block 704 at the long arm end of the fixing plate 703 with the opening of the C-shaped connecting ring 701 at the input end of the guide pipe 5, and inserts the sliding block 704 into the opening so that it enters the internal space of the connecting ring 701; then, along the direction of the sliding groove 702 that is consistent with the arc surface of the connecting ring 701, the sliding block 704 is pushed to move in an arc within the sliding groove 702. As the sliding block 704 moves deeper along the arc-shaped sliding groove 702, the guide block 705 on the upper surface of the sliding block 704 is simultaneously embedded in the guide groove 706 on the inner wall of the sliding groove 702, ensuring that the sliding block 704 moves along the arc trajectory without deviating. When the sliding block 704 slides to the predetermined position within the sliding groove 702, the magnetic block 707 on the inner wall of the sliding groove 702 attracts the iron sliding block 704, temporarily fixing the sliding block 704 in place. At this time, the L-shaped arm of the fixing plate 703 and the C-shaped opening of the connecting ring 701 form a preliminary engagement. Next, the operator inserts the sliding rod 708 downward through the through hole on the upper surface of the connecting ring 701. At this time, the arc surface of the sliding rod 708 abuts against one end surface of the sliding block 704, thereby restricting the reverse movement of the sliding block 704 within the arc-shaped sliding groove 702. Then, a rubber friction pad 709 is fitted onto the arc surface at the bottom end of the sliding rod 708, and the fixing ring 710 is tightened. During the tightening of the retaining ring 710, the friction pad 709 is pressed between the retaining ring 710 and the lower surface of the connecting ring 701, and the arc surface of the sliding rod 708 always abuts against the end face of the sliding block 704. The high coefficient of friction of the rubber and the pressure of the contact surface work together to prevent the threads and the sliding block 704 from loosening due to vibration. When disassembly is required, the operator first loosens the retaining ring 710 in the opposite direction, removes the friction pad 709, and then pulls the sliding rod 708 upward, so that the arc surface of the sliding rod 708 is separated from the end face of the sliding block 704. Then, overcoming the attraction force of the magnetic block 707, the sliding block 704 is slid out from the opening of the connecting ring 701 along the opposite direction of the arc-shaped sliding groove 702, thus completing the separation.

[0039] When it is necessary to collect condensate or solid impurities precipitated after coke oven gas cooling, the operator first pushes the collection box 81 to below the output end of the guide pipe 5 using the four rollers 82 at the bottom of the collection box 81. Then, the operator holds the rotating rod 852 in the clamping assembly 85 on the upper side of the collection box 81. The rotating rod 852 is threaded through both ends of the fixing frame 851, and one end of the rotating rod 852 is rotatably connected to a C-shaped clamp 853. The operator rotates the rotating rod 852 with anti-slip texture 854 by hand, causing the rotating rod 852 to move forward and push the C-shaped clamp 853 gradually closer to the arc surface of the output end of the guide pipe 5. The rotating rods 852 on both sides are adjusted to make the two clamps 853 symmetrically move towards the middle from the left and right sides until the inner wall of the clamp 853 is tightly against the arc surface of the output end of the guide pipe 5, thereby fixing the collection box 81 at the outlet of the guide pipe 5. Meanwhile, the operator can hold the U-shaped handle 83 with anti-slip sleeve 84 at one end of the collection box 81 to assist in adjusting its position. During the coke oven gas cooling and impurity removal process, the condensate or impurities flowing out from the output end of the guide pipe 5 fall directly into the collection box 81. When it is necessary to empty the collection box 81, the operator rotates the rotating rod 852 in the opposite direction to loosen the clamp 853 from the output end of the guide pipe 5, and then pulls the collection box 81 out and removes it using the handle 83 and roller 82.

[0040] When the collection box 81 needs to be installed onto the body 1, the operator first aligns the limiting grooves 97 at both ends of the collection box 81 with the limiting blocks 96 fixed on both sides of the body 1, and then lowers the collection box 81 vertically downwards. As the collection box 81 moves downwards, the limiting blocks 96 slide vertically into the limiting grooves 97, providing vertical guidance and horizontal limitation for the collection box 81; at the same time, the bottom of the collection box 81 gradually approaches the limiting plate 98 on the surface of the body 1. When approaching the lowest position, the pointed conical guide block 95 at the bottom of the insertion rod 92 first contacts the edge of the corresponding insertion hole on the surface of the body 1. Because the guide block 95 has an inclined conical surface, as the collection box 81 continues to descend, the guide block 95 is squeezed by the edge of the insertion hole, forcing the insertion rod 92 to overcome the elastic force of the spring 93 and move outwards, causing the insertion rod 92 to retract. When the collection box 81 is fully lowered to its lowest position and its bottom end abuts against the upper surface of the limiting plate 98, the insertion rod 92 is aligned with the insertion hole of the machine body 1. At this time, the elastic force of the spring 93 pushes the insertion rod 92 to return to its original position, and the end of the insertion rod 92 extends and locks into the insertion hole of the machine body 1, thereby preventing the collection box 81 from lifting upward and coming out. When it is necessary to disassemble the collection box 81, the operator manually pulls the pull ring 94 at the end of the insertion rod 92, causing the insertion rod 92 to retract outward again against the elastic force of the spring 93, releasing the locking state, and then lifts the collection box 81 upward until the collection box 81 is completely separated from the machine body 1.
