Description

Technical Field

[0001] The utility model relates to the field of heating urea pipes, in particular to a vibration type heating urea pipe assembly. Background Art

[0002] The vibration heating urea pipe assembly is a device used in the exhaust purification system of diesel vehicles. It is designed to prevent the urea solution from crystallizing in a low temperature environment and improve the mixing uniformity of the urea solution by means of vibration and heating.

[0003] The existing patent CN215719041U discloses an anti-interference vibration type heating urea pipe. Compared with the prior art, the utility model has the following beneficial effects: by turning on the circuit switch of the vibration plate, the vibration plate starts to vibrate, and through the transmission effect of the telescopic vibration rod, the vibration is transmitted to the pipe body, driving the liquid to vibrate, and at the same time, through the joint vibration effect of the side buffer spring, the whole pipe body vibrates more violently, and the outside personnel can also loosen the locking threaded part to separate the locking threaded part from the outer surface of the vibration frame, driving the vibration plate to move, and the vibration plate can change during the movement. After the vibration amplitude of the pipe body moves to the designated area, the locking threaded part is tightened to complete the fixing effect. The vibration amplitude can be changed according to different vibration requirements to achieve a better liquid mixing effect. The external connecting piece is embedded in the semicircular clamping ring, and then the tightening belt is directly pulled. During the pulling process, the clockwork spring is driven to deform. After the clockwork spring is deformed, it can generate elastic force to tighten the tightening belt, and then the tightening belt is wrapped around the external connecting piece, and finally fixed in the tie rod, which can make the connection between the connecting piece and the connecting component more stable, and at the same time, the installation of the pipe body can be better completed.

[0004] The above technical solution sets a vibration component. When the vibration plate vibrates, the telescopic vibration rod transmits the vibration generated by the vibration plate to the tube body, causing the tube body itself to vibrate, thereby heating the solution inside the tube body. By controlling the position of the vibration plate, the vibration amplitude of the tube body is adjusted to achieve a better liquid mixing effect. However, the above solution still has the problem of a single vibration direction of the tube body. Specifically, when the vibration plate vibrates, the telescopic vibration rod can only drive the tube body to vibrate left and right, resulting in a single vibration direction, which is not conducive to promoting heat convection in the solution and causes uneven heat distribution. Therefore, the utility model proposes a vibration-type heating urea tube assembly. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings in the prior art and provide a vibration type heating urea pipe assembly.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a vibration-type heating urea pipe assembly, comprising a urea pipe body, a heating assembly, and a fixing assembly, wherein connecting pipes are arranged at both ends of the urea pipe body, the heating assembly is arranged on the urea pipe body, a rotating assembly is arranged on one side of the urea pipe body close to the heating assembly, and the fixing assembly is arranged on one side of the urea pipe body close to the heating assembly;

[0007] The heating assembly includes a shell and a transmission block. The shell is arranged on the urea tube body. A driven wheel is arranged inside the shell. The urea tube body is movably inserted inside the driven wheel. A rotating shaft is rotatably connected to a side of the shell close to the driven wheel. An eccentric block is fixedly connected to an end of the rotating shaft away from the driven wheel. The transmission block is fixedly connected to a side of the urea tube body close to the eccentric block. The urea tube body is transmission-connected to the eccentric block via the transmission block.

[0008] As a preferred implementation, a motor is fixedly connected to the housing, a driving wheel is fixedly connected to the output end of the motor, and a transmission belt is transmission-connected between the driving wheel and the driven wheel.

[0009] The technical effect of adopting the above further solution is: starting the motor so that the motor drives the driving wheel to rotate, and then the driving wheel drives the driven wheel to rotate through the transmission block.

[0011] The technical effect of adopting the above further solution is: rotating the driven wheel will drive the rack inside it to rotate, the rack drives the shaft to rotate through the gear, and then the shaft drives the eccentric block to rotate, so that the eccentric block pushes the transmission block to move.

[0012] As a preferred embodiment, the rotating assembly includes a slider and a slide groove, the slider is fixedly connected to the driven wheel, the slide groove is opened on a side of the housing close to the slider, and the housing is rotatably connected to the housing through the slider and the slide groove.

[0013] The technical effect of adopting the above further solution is: the slider is fixed on the driven wheel, and the slider is arranged inside the slide groove, so that the driven wheel rotates along the slide groove through the slider, thereby increasing the stability of the housing during rotation.

[0014] As a preferred embodiment, a limiting plate is fixedly connected to one side of the urea tube body close to the shell, a limiting groove is provided on one end of the shell close to the limiting plate, the limiting plate is movably connected to the limiting groove, and the diameter of the limiting plate is smaller than the diameter of the limiting groove.

[0015] The technical effect of adopting the above further scheme is: a limit plate is installed on the urea tube body, and when the eccentric block drives the urea tube body to vibrate, the limit plate moves inside the limit groove following the urea tube body, and after the urea tube body moves a certain distance, the outer side of the limit plate contacts the inner wall of the limit groove, and then the urea tube body is limited by the limit plate, so as to prevent the transmission block on the urea tube body from always keeping in contact with the eccentric block.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] 1. By setting a heating component, by inserting the urea tube body into the shell and rotating the shaft, the eccentric block can be driven to rotate. Due to the eccentric structure of the eccentric block and the different directions thereof, during the rotation process, the eccentric block can push the urea tube body to continuously deviate inside the shell through the transmission block. This deviation causes the urea tube body to vibrate in different directions inside the shell, thereby heating the solution inside it from multiple directions, thereby effectively promoting heat convection in the solution, which is conducive to making the heat distribution more uniform, achieving a more uniform heating effect, and improving the overall heating efficiency.

[0020] 2. By setting a fixing component, by sleeve-mounting the sleeve on the urea tube body, and fixing the fixing plate 1 on the external device, when the urea tube body vibrates, the urea tube body drives the fixing plate 2 to vibrate through the sleeve.

This design can effectively avoid reducing the vibration effect of the urea tube body, thereby improving the working efficiency and service life of the urea tube body.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] like Figure 1-Figure 6As shown, this embodiment provides a technical solution: a vibration-type heating urea pipe assembly, comprising a urea pipe body 1, a heating assembly 2, and a fixing assembly 3, wherein connecting pipes 4 are arranged at both ends of the urea pipe body 1, the heating assembly 2 is arranged on the urea pipe body 1, a rotating assembly 5 is arranged on one side of the urea pipe body 1 close to the heating assembly 2, and the fixing assembly 3 is arranged on one side of the urea pipe body 1 close to the heating assembly 2;

[0036] like Figure 2-Figure 5 As shown, the heating assembly 2 includes a shell 21 and a transmission block 25. The shell 21 is arranged on the urea tube body 1. A driven wheel 24 is arranged inside the shell 21. The urea tube body 1 is movably inserted inside the driven wheel 24. A rotating shaft 27 is rotatably connected to one side of the shell 21 close to the driven wheel 24. An eccentric block 26 is fixedly connected to one end of the rotating shaft 27 away from the driven wheel 24. The transmission block 25 is fixedly connected to one side of the urea tube body 1 close to the eccentric block 26. The urea tube body 1 is transmission-connected to the eccentric block 26 through the transmission block 25. The urea tube body 1 is inserted into the shell 21, and the rotating shaft 27 is rotated. The rotating shaft 27 drives the eccentric block 26 to rotate. Since the eccentric block 26 is an eccentric structure and the eccentric block 26 faces different directions, the eccentric block 26 pushes the urea tube body 1 to continuously deviate inside the shell 21 through the transmission block 25, so that the urea tube body 1 vibrates in different directions inside the shell 21, so that the urea tube body 1 heats the solution inside from multiple directions, thereby solving the problem of promoting heat convection in the solution and causing uneven heat distribution.

[0037] Furthermore, Figure 2 As shown, a motor 22 is fixedly connected to the housing 21, a driving wheel 23 is fixedly connected to the output end of the motor 22, a transmission belt 6 is connected between the driving wheel 23 and the driven wheel 24, and by starting the motor 22, the motor 22 drives the driving wheel 23 to rotate, and then the driving wheel 23 drives the driven wheel 24 to rotate through the transmission block 25.

[0038] Furthermore, Figure 4 As shown, a gear 28 is fixedly connected to one end of the rotating shaft 27 away from the eccentric block 26, and a rack 29 is fixedly connected to the side of the driven wheel 24 close to the gear 28. The gear 28 is meshed with the rack 29. The rotating shaft 27 is connected to the driven wheel 24 through the gear 28 and the rack 29. By rotating the driven wheel 24, the driven wheel 24 will drive the rack 29 inside it to rotate, and the rack 29 drives the rotating shaft 27 to rotate through the gear 28, and then the rotating shaft 27 drives the eccentric block 26 to rotate, so that the eccentric block 26 pushes the transmission block 25 to move.

[0039] In the above solution, there is still a problem that the driven wheel 24 is not stable enough when rotating on the housing 21, such as Figure 3 and Figure 5As shown, the rotating component 5 includes a slider 51 and a slide groove 53. The slider 51 is fixedly connected to the driven wheel 24. The slide groove 53 is opened on a side of the shell 21 close to the slider 51. The shell 21 is rotatably connected to the shell 21 through the slider 51 and the slide groove 53. By fixing the slider 51 on the driven wheel 24 and arranging the slider 51 inside the slide groove 53, the driven wheel 24 can rotate along the slide groove 53 through the slider 51, thereby increasing the stability of the shell 21 during rotation.

[0040] In the above solution, there is still a situation where the urea tube body 1 slips during displacement, such as Figure 5 As shown, a limiting plate 52 is fixedly connected to one side of the urea tube body 1 close to the shell 21, and a limiting groove 54 is provided on one end of the shell 21 close to the limiting plate 52. The limiting plate 52 is movably connected to the limiting groove 54, and the diameter of the limiting plate 52 is smaller than the diameter of the limiting groove 54. By installing the limiting plate 52 on the urea tube body 1, when the eccentric block 26 drives the urea tube body 1 to vibrate, the limiting plate 52 moves inside the limiting groove 54 following the urea tube body 1. After the urea tube body 1 is displaced a certain distance, the outer side of the limiting plate 52 contacts the inner wall of the limiting groove 54, and then the urea tube body 1 is limited by the limiting plate 52, so as to prevent the transmission block 25 on the urea tube body 1 from always keeping in contact with the eccentric block 26.

[0041] In the above scheme, there is still a situation where the vibration effect is reduced after the urea tube body 1 is fixed, such as Figure 6 As shown, the fixing assembly 3 includes a fixing plate 1 31 and a sleeve 33. The sleeve 33 is sleeved on one end of the urea tube body 1 close to the shell 21. A fixing plate 2 32 is fixedly connected to one side of the sleeve 33. The fixing plate 1 31 is arranged on the side of the fixing plate 2 32 away from the sleeve 33. A damping telescopic rod 34 is arranged between the fixing plate 1 31 and the fixing plate 2 32. A spring 35 is sleeved on the damping telescopic rod 34. The spring 35 is fixedly connected between the fixing plate 1 31 and the fixing plate 2 32. By sleeve-mounting the sleeve 33 on the urea tube body 1 and fixing the fixing plate 1 31 on an external device, when the urea tube body 1 vibrates, the urea tube body 1 drives the fixing plate 2 32 to vibrate through the sleeve 33. When the fixing plate 2 32 vibrates, the damping telescopic rod 34 cooperates with the spring 35 to keep the urea tube body 1 vibrating, thereby avoiding reducing the vibration effect of the urea tube body 1.

[0042] Working principle: Figure 1-Figure 6 As shown:

[0043] When in use: first sleeve the sleeve 33 on the urea tube body 1, then fix the shell 21 and the fixing plate 31 on the external device, connect the connecting pipes 4 at both ends of the urea tube body 1 to the output end and the input end respectively, start the motor 22, the motor 22 drives the driving wheel 23 to rotate, the driving wheel 23 drives the driven wheel 24 to rotate through the transmission belt 6, and the driven wheel 24 rotates through the rack 29 inside it. Since the rack 29 is meshed with the gear 28, the rack 29 drives the gear 28 to rotate, so that the gear 28 drives the eccentric block 26 to rotate through the rotating shaft 27. When the eccentric block 26 rotates, it will push the transmission block 25 to deviate and rotate inside the shell 21, so that the transmission block 25 drives the urea tube body 1 to vibrate, and the solution inside the urea tube body 1 is heated. Since the urea tube body 1 vibrates in different directions, it can effectively promote the heat convection in the urea solution, so that the heat distribution is more uniform.

[0044] When the urea tube body 1 vibrates, the urea tube body 1 drives the second fixing plate 32 to vibrate through the sleeve 33, and then the damping telescopic rod 34 cooperates with the transmission block 25 to keep the urea tube body 1 vibrating, thereby avoiding reducing the vibration effect of the urea tube body 1.

[0045] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
