Description

Technical Field

[0001] This utility model relates to the field of heat exchange device technology, specifically a self-cleaning heat exchange device for sewage treatment. Background Technology

[0002] A heat exchanger is a device used for heat exchange, which achieves efficient energy utilization by transferring heat from one fluid to another. Heat exchangers can be used to regulate the temperature of wastewater to meet the requirements of subsequent treatment processes. Heat exchangers can also perform functions such as heat recovery and mass transfer. There are various types of heat exchangers, among which shell-and-tube heat exchangers are commonly used in wastewater treatment. However, existing heat exchange devices have limitations in use. The inlet A does not have an anti-clogging structure, which makes it easy for wastewater to become clogged when it enters the tube box through inlet A. It is also inconvenient for workers to clean the inside of inlet A, thus affecting the heat exchange efficiency during wastewater treatment. Therefore, there are certain limitations in its use and room for improvement. Utility Model Content

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a self-cleaning heat exchanger for sewage treatment includes a shell 1. Pipe boxes 2 are symmetrically installed at both ends of the shell 1. An inlet A3 is fixed to the top surface of one pipe box 2, and a drain outlet B6 is fixed to the bottom surface of the other pipe box 2. An inlet B4 is installed at the top of one end of the shell 1, and a drain outlet A5 is installed at the bottom of the other end. A support 7 is symmetrically arranged at the bottom surface of the shell 1. A first functional component is provided at the opening of the inlet A3. The first functional component includes an installation pipe 8 located at the opening of the inlet A3. Multiple steel wires 9 are installed inside the installation pipe 8. The length of the steel wires 9 is greater than the width of the opening of the installation pipe 8. The installation pipe 8 is connected to the inlet A3 by bolts. Multiple through grooves 11 are formed on the surface of the installation pipe 8 for the steel wires 9 to pass through. A dense... The sealing plug 10 has multiple steel wires 9 inside the installation pipe 8 arranged in a staggered manner from top to bottom. The sealing plug 10 is made of rubber and has a threaded head 12 installed at one end. The end surfaces of the sealing plug 10 and the threaded head 12 have installation holes 13 for the steel wires 9 to pass through and engage. The threaded head 12 is screwed into the installation hole 13. The length of the threaded head 12 is less than the inner wall depth of the through groove 11. The inner wall of the through groove 11 has threads. The cross-section of the sealing plug 10 is an isosceles trapezoid. The side surface of one end of the sealing plug 10 is tightly fitted to the inner wall of the opening of the through groove 11, which facilitates the crushing of impurities in the sewage. This makes it less likely for sewage to become blocked when it enters the inlet A3 through the installation pipe 8, allowing sewage to quickly enter the pipe box 2 through the inlet A3. This improves functionality and has a better practical effect.

[0021] like Figure 1 and Figure 4As shown, a second functional component is provided on one side of inlet A3 and inlet B4. The second functional component includes flushing pipes 14 respectively installed on one side of inlet A3 and inlet B4. A solenoid valve 15 is fixed to one end of each flushing pipe 14. A fixing pipe 16 is provided between the two solenoid valves 15. A connecting water pipe 17 is snapped into the middle of one side of the fixing pipe 16. One end of the connecting water pipe 17 is connected to an external water pump, which facilitates the periodic flushing of the inside of the pipe box 2 and the shell 1. This prevents impurities from adhering to the inner wall of the pipe box 2 and the inner wall of the shell 1, thus avoiding the impact on the heat exchange efficiency of the heat exchange device. This makes it practical.

[0022] This utility model provides a self-cleaning heat exchange device for sewage treatment. The specific working principle is as follows: During the initial installation of the first functional component, steel wires 9 are first threaded through the through-groove 11 on the surface of the mounting pipe 8, so that multiple steel wires 9 are interlaced inside the mounting pipe 8, with both ends of the steel wires 9 outside the opening of the through-groove 11. Then, the through-groove 11 and the threaded head 12 are pushed towards the ends of the steel wires 9, allowing both ends of the steel wires 9 to pass through the mounting holes 13 on the surfaces of the sealing plug 10 and the threaded head 12. The sealing plug 10 is then rotated, causing the threaded head 12 to rotate into the through-groove 11 until the threaded head 12 is completely rotated into the through-groove 11. At this point, one side surface of the sealing plug 10 is pressed against the inner wall of the opening at one end of the through-groove 11, thus sealing the inside of the through-groove 11. The above steps can then be repeated to install other sealing plugs 10 and threaded heads 12 at the ends of the steel wires 9 until… After all the steel wires 9 are installed and positioned, the installation pipe 8 can be pushed towards the top of the opening of the inlet A3, so that one end of the installation pipe 8 is aligned with the end surface of the inlet A3. Then, the installation pipe 8 and the inlet A3 are fixedly connected by bolts. When sewage enters the inlet A3 through the installation pipe 8, the steel wires 9 inside the installation pipe 8 can break up the impurities in the sewage, so that the sewage will not cause blockage inside the inlet A3, thus improving functionality and practical effect. When it is necessary to clean the inside of the pipe box 2 and the shell 1, this utility model only needs to connect one end of the connecting water pipe 17 to the external water pump, and then start the two solenoid valves 15, so that the connecting water pipe 17 can deliver clean water to the two flushing pipes 14 through the fixed pipe 16. The two flushing pipes 14 can then flush the inside of the pipe box 2 and the shell 1 through the inlet A3 and the inlet B4 respectively, without the need for manual cleaning, thus avoiding the impact on the heat exchange efficiency of the heat exchange device, and thus having a good practical effect.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
