Description

Technical Field

[0001] The utility model relates to an evaporator head structure and belongs to the technical field of evaporator tools. Background Art

[0002] The evaporator is a shell-and-tube heat exchanger. The tube side is used for the inflow and outflow of liquid, and the shell side is used for heating steam. The liquid material enters from the top of the evaporator, enters the heating tube through the distributor, and flows down along the heating tube. It is evaporated during the heating process, and the concentrated liquid and gas are separated. At the same time, an air inlet pipe is also provided on one side of the feed pipe at the upper end of the evaporator, and a film plate is provided under the feed pipe. Existing technologies such as Figure 3 As shown, during use, the applicant found that with the feeding and air intake process, a siphon phenomenon would occur around the feed pipe and the air intake pipe. In this way, after the material or gas contacts the membrane disk, the rebound and the siphon phenomenon will cause the gas to carry the slurry to impact the top surface of the evaporator. After the previous use, the top surface of the evaporator is prone to penetration, which seriously affects the stable operation of the evaporator and the entire production line.

[0003] Therefore, a structure is now needed that can avoid wear of the top of the evaporator, that is, the evaporator head, which is beneficial to increasing the service life of the evaporator and maintaining the stability of system operation. Summary of the invention

[0004] In view of this, the purpose of the utility model is to provide an evaporator head structure, which is beneficial to improving the service life of the evaporator and maintaining the stability of system operation, and can overcome the shortcomings of the prior art.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] The utility model discloses an evaporator head structure, which comprises an evaporator body, a slurry feed pipe and an air inlet pipe are arranged at the upper end of the evaporator body, a discharge pipe is arranged at the lower end of the evaporator body, a film cloth disk is arranged below the slurry feed pipe, and a trumpet-shaped baffle with an opening facing downward is arranged at the lower end of the slurry feed pipe, the trumpet-shaped baffle is located between the air inlet pipe and the film cloth disk, and the lower end of the trumpet-shaped baffle is located on the upper side of the film cloth disk.

[0007] As mentioned above, a feed outlet communicated with the slurry feed pipe is provided at the upper end of the trumpet-shaped baffle, and a butt joint pipe butted with the slurry feed pipe is provided on the feed outlet.

[0008] The trumpet-shaped baffle and the butt-joint pipe, and the butt-joint pipe and the slurry feed pipe are welded and fixed.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The utility model provides a trumpet-shaped baffle with an opening downward at the lower end of the slurry feed pipe, and the trumpet-shaped baffle is located between the air inlet pipe and the film cloth disk, and the lower end of the trumpet-shaped baffle is located on the upper side of the film cloth disk. Such a structure can, when in use, when the slurry is discharged or the air inlet pipe is intaken, the trumpet-shaped baffle can not only shield the inner top surface of the evaporator, thereby avoiding the impact of gas or slurry on the inner top surface of the evaporator during siphoning, but also can disperse part of the gas along the upper surface of the trumpet-shaped baffle when the air inlet pipe is intaken, thereby reducing the strength of the siphoning, thereby indirectly protecting the inner top surface of the evaporator, which is beneficial to increasing the service life of the evaporator and maintaining the stable operation of the system.

[0011] 2. A feed port connected to the slurry feed pipe is provided at the upper end of the trumpet-shaped baffle, and a docking tube docking with the slurry feed pipe is provided on the feed port. In this way, the distance between the trumpet-shaped baffle and the top surface of the evaporator can be increased through the docking tube, thereby increasing the space and gap for air intake through the air intake pipe and facilitating the installation of the trumpet-shaped baffle and the slurry air intake pipe.

[0012] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and will be apparent to those skilled in the art based on the following examination and research, or can be taught from the practice of the present invention to some extent. The objectives and other advantages of the present invention can be achieved and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.

[0019] like Figure 1-Figure 2As shown, the utility model discloses an evaporator head structure, which is used to protect the inner top surface of the evaporator body 1. Specifically, a slurry feed pipe 2 and an air inlet pipe 3 are provided at the upper end of the evaporator body 1, a discharge pipe 4 is provided at the lower end of the evaporator body 1, a film cloth plate 5 is provided below the slurry feed pipe 2, and a trumpet-shaped baffle 6 with an opening downward is provided at the lower end of the slurry feed pipe 2. The slurry is fed into the trumpet-shaped baffle 6, and the trumpet-shaped baffle 6 is located between the air inlet pipe 3 and the film cloth plate 5 and below the trumpet-shaped baffle 6. The end is located on the upper side of the film disk 5. With such a structure, when the slurry is discharged from the slurry feed pipe 2, even if siphoning occurs, the trumpet-shaped baffle 6 can block it, thereby reducing the impact of the slurry or gas on the inner top surface of the evaporator body 1, avoiding damage to the inner top surface of the evaporator body 1. At the same time, when the air inlet pipe 3 takes in air, the upper surface of the trumpet-shaped baffle 6 can also play a role in dispersing the gas. The dispersed gas is also conducive to reducing the generation of siphoning or weakening the strength of siphoning, and can also indirectly protect the evaporator body 1.

[0020] Furthermore, a feed port connected to the slurry feed pipe 2 is provided at the upper end of the trumpet-shaped baffle 6, and a docking tube 7 docked with the slurry feed pipe 2 is provided on the feed port. During installation, the trumpet-shaped baffle 6 and the docking tube 7, as well as the docking tube 7 and the slurry feed pipe 2 are welded and fixed. In this way, adding the docking tube 2 not only facilitates the installation of the trumpet-shaped baffle 6, but also helps to increase the distance between the air inlet of the air inlet pipe 3 and the trumpet-shaped baffle 6, thereby avoiding air intake obstruction.

[0021] The above is only a preferred embodiment of the utility model, and does not limit the confidentiality of the utility model in any form. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still falls within the scope of the technical solution of the utility model.
