Description

Technical Field

[0001] This utility model belongs to the technical field of exhaust gas purification devices, specifically relating to a diesel engine exhaust gas purification device with high sealing performance. Background Technology

[0002] In sectors such as industrial production and transportation that rely on diesel engine power, diesel engine exhaust purification devices play an indispensable and crucial role as core equipment for controlling pollutant emissions. Through internal catalytic conversion and particulate capture technologies, they can efficiently remove harmful components such as nitrogen oxides, particulate matter, and carbon monoxide from diesel engine exhaust, strictly controlling the concentration of exhaust pollutants within the normal emission standards stipulated by the state and industry. They are an essential supporting facility for achieving green operation of diesel engines.

[0003] However, in actual installation and application, the clamps used to connect and fix the diesel engine and the purifier have a significantly insufficient bottom height. This height deficiency directly results in the clamp's bottom failing to form a stable and effective supporting contact with the connection between the diesel engine and the purifier after installation, leaving the clamp's bottom suspended and unable to bear the weight and fixation of the connected equipment. This unstable support state will cause frequent friction and loosening between the clamp and the connection during diesel engine operation due to equipment vibration. Long-term use may lead to clamp breakage, loosening of the mating ends, and other hidden dangers. In severe cases, it may even affect the normal operation of the diesel engine, increasing equipment maintenance costs and the risk of failure. Utility Model Content

[0004] The purpose of this invention is to provide a diesel engine exhaust gas purification device with high sealing performance. This addresses the problem that a high degree of sealing directly leads to the clamp's bottom failing to form a stable and effective supporting contact with the connection between the diesel engine and the purifier after installation, causing the clamp bottom to be suspended and unable to bear the weight and fixation of the connected equipment. This unstable support state will cause frequent friction and loosening between the clamp and the connection during diesel engine operation due to equipment vibration. Long-term use may lead to clamp breakage, loosening of the mating end, and other potential problems. In severe cases, it may even affect the normal operation of the diesel engine, increasing equipment maintenance costs and the risk of failure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a diesel engine exhaust gas purification device with high sealing performance, including an exhaust gas purifier, a flange connecting pipe installed at the bottom of one end of the exhaust gas purifier, an exhaust pipe installed at the top of the other end of the exhaust gas purifier, detachable clamps symmetrically installed on the surface of the exhaust gas purifier, and two base plates symmetrically welded to the bottom of the clamps.

[0006] The bottoms of the two base plates are welded to the surfaces at both ends of the horizontal plate. The bottom of the center end of the horizontal plate is movably connected to the top of the screw. The bottom of the screw is screwed into the inside of the docking post. The bottom of the docking post is welded to the surface of the mounting plate. The two ends of the mounting plate are movably in contact with the bottom of the adjusting strip. The top of the adjusting strip is welded to the outer wall of one end of the horizontal plate.

[0007] In order to maintain a stable connection structure between the mounting plate and the horizontal plate, as a diesel engine exhaust gas purification device with high sealing performance according to this utility model, preferably, a fixing plate is welded to the outer wall of each end of the mounting plate, and two positioning strips are symmetrically welded to the outer wall of one side of the fixing plate. The bottom of the adjusting strip is movably set in the area enclosed by the fixing plate and the positioning strip.

[0008] In order to lock the adjusting strip and the fixing plate together with the bolt through the nut, as a diesel engine exhaust gas purification device with high sealing performance according to this utility model, preferably, a first through-slot is opened at the longitudinal midline of the fixing plate, and a second through-slot is opened at the longitudinal midline of the adjusting strip, and the second through-slot and the first through-slot are arranged opposite to each other.

[0009] A bolt is provided through one side of the second groove, one end of the bolt is screwed to a nut, and one side of the nut is movably mounted on the outer wall of the fixing plate.

[0010] To prevent the nut from rotating due to the rotation of the bolt, thereby improving the ease of connection between the nut and the bolt, as a diesel engine exhaust gas purification device with high sealing performance according to this utility model, preferably, two T-shaped sliders are symmetrically welded on the outer wall of the bolt-fixed plate connection end. Each T-shaped slider is slidably installed in a corresponding T-shaped groove. The T-shaped groove is opened inside the fixed plate, and the two T-shaped grooves are symmetrically arranged about the longitudinal midline of the fixed plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When the installation height of the exhaust gas purifier needs to be adjusted, the screw is adjusted from the inside to the outside of the connecting column. This screw will push the horizontal plate upward. As the horizontal plate moves upward, it will also move the adjusting strip upward, thus allowing the height of the exhaust gas purifier to be adjusted to suit the installation requirements.

[0013] After adjusting the height of the exhaust purifier, tighten the bolt. When the bolt rotates inside the nut, the nut will not rotate with the bolt due to the cooperation of the T-shaped slider and the T-shaped groove. In this way, the bolt can smoothly complete the locking operation with the nut, making it more convenient to fix the adjustment strip on the fixing plate. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 The present invention provides the following technical solution: a diesel engine exhaust gas purification device with high sealing performance, including an exhaust gas purifier 1, a flange connecting pipe 2 installed at the bottom of one end of the exhaust gas purifier 1, an exhaust pipe 3 installed at the top of the other end of the exhaust gas purifier 1, and detachable clamps 4 symmetrically installed on the surface of the exhaust gas purifier 1, with two bottom plates 5 symmetrically welded to the bottom of the clamps 4.

[0022] In use, connect the flange connecting pipe 2 at one end of the exhaust gas purifier 1 to the flange on the diesel engine exhaust pipe. Then, mount the exhaust gas purifier 1 onto the diesel engine block using two sets of mounting plates 9. The exhaust gas emitted from the diesel engine's exhaust pipe will enter the exhaust gas purifier 1. The exhaust gas purifier 1 will treat the diesel engine's exhaust gas through its internal filter element, and the treated, compliant gas will be discharged through the exhaust pipe 3. After the flange connecting pipe 2 and the flange on the diesel engine's exhaust pipe are connected, a good sealing structure is formed at the connection end, which can prevent untreated diesel engine exhaust gas from leaking at the connection end of the flange connecting pipe 2.

[0023] The bottom of the two base plates 5 are welded to the surfaces of both ends of the horizontal plate 6. The bottom of the center end of the horizontal plate 6 is movably connected to the top of the screw 7. The bottom of the screw 7 is screwed into the inside of the docking post 8. The bottom of the docking post 8 is welded to the surface of the mounting plate 9. The two ends of the mounting plate 9 are in movable contact with the bottom of the adjusting strip 96. The top of the adjusting strip 96 is welded to the outer wall of one end of the horizontal plate 6.

[0024] Preferably, a fixing plate 91 is welded to the outer wall of each end of the mounting plate 9, and two positioning strips 95 are symmetrically welded to the outer wall of one side of the fixing plate 91. The bottom of the adjusting strip 96 is movably set in the area enclosed by the fixing plate 91 and the positioning strips 95.

[0025] Preferably, a first through-slot 92 is provided at the longitudinal midline of the fixed plate 91, and a second through-slot 97 is provided at the longitudinal midline of the adjusting strip 96, with the second through-slot 97 and the first through-slot 92 being arranged opposite to each other.

[0026] In practical use, when adjusting screw 7, bolt 93 is loosened first, so that screw 7 will push the horizontal plate 6 upward during adjustment. When the horizontal plate 6 moves upward, it will drive the adjusting bar 96 upward. When the adjusting bar 96 moves upward, it will move within the area enclosed by the fixed plate 91 and the positioning bar 95 under the constraint of bolt 93 and nut 94, thus ensuring the stability of the adjusting bar 96 during movement.

[0027] Preferably, a bolt 93 is provided through one side of the second strip groove 97, one end of the bolt 93 is screwed to a nut 94, and one side of the nut 94 is movably mounted on the outer wall of the fixing plate 91.

[0028] Preferably, two T-shaped sliders 941 are symmetrically welded to the outer wall of the mating end of the bolt 93 and the fixing plate 91. Each T-shaped slider 941 is slidably installed in a corresponding T-shaped groove 942. The T-shaped groove 942 is opened inside the fixing plate 91, and the two T-shaped grooves 942 are symmetrically arranged about the longitudinal midline of the fixing plate 91.

[0029] When bolt 93 is tightened, it adjusts along the threaded path inside nut 94. Nut 94, with the cooperation of T-shaped slider 941 and T-shaped groove 942, will not rotate with bolt 93. This allows bolt 93 to smoothly complete the tightening operation with nut 94, thereby pressing and tightening adjusting strip 96 and fixing plate 91 together. Furthermore, with the cooperation of screw 7 and connecting post 8, it can be stably supported at the bottom of horizontal plate 6.

[0030] In practical use, when it is necessary to adjust the installation height of the exhaust gas purifier 1, the screw 7 is adjusted from the inside to the outside of the docking column 8. This screw 7 will push the horizontal plate 6 upward. When the horizontal plate 6 moves upward, it will drive the adjusting strip 96 upward, so that the height of the exhaust gas purifier 1 can be adjusted to suit the installation requirements.

[0031] After adjusting the height of the exhaust gas purifier 1, tighten the bolt 93. When the bolt 93 rotates inside the nut 94, the nut 94 will not rotate with the bolt 93 due to the cooperation of the T-shaped slider 941 and the T-shaped groove 942. In this way, the bolt 93 can smoothly complete the locking operation with the nut 94, which makes it more convenient to fix the adjusting strip 96 on the fixing plate 91.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
